The present invention generally relates to the field of mounting components to building surfaces and, more particularly, using a rail to mount components to a building surface.
Metal panels are being increasingly used to define building surfaces such as roofs and sidewalls. One type of metal panel is a standing seam panel, where the edges of adjacent standing seam panels of the building surface are interconnected in a manner that defines a standing seam. Standing seam panels are expensive compared to other metal panels, and building surfaces defined by metal panels may be more costly than other types of building surface constructions.
Other types of metal panels are commercially available and can be used to define a roofing surface. One such panel configuration is commonly referred to as a trapezoidal rib panel (e.g., formed from an appropriate metal alloy). Such a trapezoidal rib panel may include one or more trapezoidal ribs with a base section positioned on each side thereof, and furthermore may include one or more minor ribs (although some trapezoidal rib panels may in fact not use any minor ribs). In any case, an edge portion of one trapezoidal rib panel may be nested with an edge portion of an adjacent trapezoidal rib panel to collectively define a trapezoidal rib as well.
It is often desirable to install various types of structures on building surfaces, such as heating, air conditioning, and ventilation equipment. Photovoltaic or solar cells have existed for some time, and have been installed on various building roofs. A photovoltaic cell is typically incorporated into a perimeter frame of an appropriate material (e.g., aluminum) to define a photovoltaic module or solar cell module. Multiple photovoltaic modules may be arranged to define a photovoltaic module array, where rows of photovoltaic modules are typically disposed perpendicular to the pitch of a sloped roofing surface and where columns of photovoltaic modules are typically disposed along the pitch of such a sloped roofing surface (e.g., a row of photovoltaic modules of a photovoltaic module array may extend/be disposed perpendicular to the pitch of a pitched roofing surface; a column of photovoltaic modules of a photovoltaic module array may extend/be disposed along the pitch of a pitched roofing surface).
The present invention pertains to a rail or a rail assembly that is attachable to a building surface, with any appropriate component or combination of components being attachable to such a rail or rail assembly. Various of the following aspects of the present invention are characterized as a “rail assembly.” Each rail assembly addressed by this Summary utilizes at least a rail. If a given aspect does not require additional components for the rail assembly in its broadest terms, such an aspect of the present invention could then of course simply be referred to as a “rail.”
A rail assembly may be installed on building surface (e.g., a roofing surface) of any appropriate type/configuration (e.g., defined by a plurality of metal/metal alloy panels). The rail assembly may be directly attached to such a building surface or such a rail assembly may be secured relative to such a building surface by one or more intermediate structures. For instance, the building surface may include a plurality of protrusions (hereafter rib(s) and protrusion(s) may be used interchangeably) that are spaced from one another and that are disposed in at least substantially parallel relation to one another relative to the respective length dimensions. These protrusions may be of any appropriate type/configuration, for instance in the form of a standing seam, a seam rib (e.g., of a nail strip panel), a rib (e.g., trapezoidal), a crown of a corrugated panel, or the like. These protrusions may be incorporated by a panel, may be defined by nesting/interconnecting a pair of adjacent panels, or both.
One embodiment has the plurality of ribs being orientated such that the elevation of each rib progressively changes proceeding along their respective length dimension (e.g., the length of the various ribs may collectively define a pitch of a roofing surface). In any case, the rail assembly may be installed that that a length dimension of a rail extends across multiple ribs, including where the length dimension of the rail is orthogonal to the length dimension of the ribs of the building surface. A given rail may be secured to any appropriate number of ribs. One embodiment has a bottom of the rail (e.g., at least a portion thereof) being disposed directly on an upper end (e.g., a flat upper end) of multiple ribs.
A first aspect of the present invention is embodied by a rail assembly that is attachable to a building surface, and includes a rail, an adapter, a first assembly configuration, and a second assembly configuration. The adapter includes a coupling section and a mounting flange. The rail includes a rail top and a rail bottom that are spaced from one another in a vertical dimension, along with first and second rail sides that are spaced from one another in a lateral dimension. The rail top includes an attachment fastener slot that extends along an entire length of the rail, where the length of the rail is within a longitudinal dimension that is orthogonal to the noted lateral dimension. The first rail side includes a first rail channel that extends along the entire length of the rail, while the second rail side includes a second rail channel that also extends along the entire length of the rail. The first and second rail channels may be of a common configuration and may be the mirror image of one another. In any case, the attachment fastener slot is located between the first and second rail channels in the noted lateral dimension.
The rail assembly of the first aspect is disposable in each of a first assembly configuration and a second assembly configuration. The first assembly configuration entails a first coupling portion of the coupling section for the adapter being slidably disposable in the first rail channel (of the rail) and the mounting flange of the adapter being disposed beyond the first rail channel such that the first coupling portion within the first rail channel is located between the mounting flange and the attachment fastener slot (of the rail) in the lateral dimension. The second assembly configuration entails the first coupling portion of the coupling section being slidably disposable in the second rail channel and the mounting flange being disposed beyond the second rail channel such that the first coupling portion within the second rail channel is located between the mounting flange and the attachment fastener slot in the lateral dimension. That is, in the case of the first aspect the rail and adapter are configured such that an adapter may be disposed on the first rail side, or this same adapter may be disposed on the second rail side. Obviously the same adapter may only be interconnected with only one of the first rail side and the second rail side at a given point in time and in the above-noted manner.
A second aspect of the present invention is embodied by a rail assembly that is attachable to a building surface, and includes a rail, an adapter, a first mounting configuration, and a second mounting configuration. The adapter includes a coupling section and a mounting flange. The rail includes a rail top and a rail bottom that are spaced from one another in a vertical dimension, along with first and second rail sides that are spaced from one another in a lateral dimension. The rail top includes an attachment fastener slot that extends along an entire length of the rail, where the length of the rail is within a longitudinal dimension that is orthogonal to the noted lateral dimension. The first rail side includes a first rail channel that extends along the entire length of the rail.
The rail assembly of the second aspect may utilize each of a first mounting configuration and a second mounting configuration. The first mounting configuration entails a first coupling portion of the coupling section for the adapter being disposed within the first rail channel in a first orientation relative to the rail, with the mounting flange being disposed beyond the first rail channel such that the first coupling portion (within the first rail channel) is located between the mounting flange and the attachment fastener slot in the lateral dimension. The second mounting configuration entails a first coupling portion of the coupling section being disposed within the first rail channel in a second orientation relative to the rail, with the second orientation being different from the first orientation associated with the first mounting configuration, and with the mounting flange being disposed beyond the first rail channel such that the first coupling portion (within the first rail channel) is located between the mounting flange and the attachment fastener slot in the lateral dimension. Consider the case where the rail bottom (at least part thereof) is disposed on a reference plane. The mounting flange and this reference plane are separated by a first distance within the vertical dimension for the first mounting configuration, while the mounting flange and this reference plane are separated by a second distance within the vertical dimension for the second mounting configuration, with the first distance (associated with the first mounting configuration) being greater than the second distance (associated with the second mounting configuration). That is, in the case of the second aspect the rail and adapter are configured such that the adapter may be installed on the first rail side in two different orientations (e.g., by inverting the adapter). Obviously the same adapter may installed in only one of the two orientations at a given point in time and in the above-noted manner.
A third aspect of the present invention is embodied by a rail assembly that is attachable to a building surface, and includes both a rail and an adapter. The rail includes a rail top and a rail bottom that are spaced from one another in a vertical dimension, along with first and second rail sides that are spaced from one another in a lateral dimension. The rail top includes an attachment fastener slot that extends along an entire length of the rail, where the length of the rail is within a longitudinal dimension that is orthogonal to the noted lateral dimension. The first rail side includes a first rail channel that extends along the entire length of the rail and that is defined by first and second rail lips that are separated by a first slot that leads into the first rail channel. The adapter includes a coupling section and a mounting flange. The coupling section includes an inner coupling section and an outer coupling section, with the inner coupling section being disposed within the first rail channel, and with the outer coupling section being spaced from the inner coupling section such that each of the first and second lips of the rail are captured between the inner coupling section and the outer coupling section of the adapter. The mounting flange extends from the outer coupling section at a location that is between first and second ends of the outer coupling section that are spaced from one another in the vertical dimension (e.g., the first and second ends of the outer coupling section may be characterized as the upper and lower extremes of the outer coupling section). The mounting flange is offset from each of the first and second ends of the outer coupling section in the vertical dimension, while the coupling section is located between the mounting flange and the attachment fastener slot in the lateral dimension.
A fourth aspect of the present invention is embodied by a rail assembly that is attachable to a building surface, and includes both a rail and an adapter. The rail includes a rail top and a rail bottom that are spaced from one another in a vertical dimension, along with first and second rail sides that are spaced from one another in a lateral dimension. The rail top includes an attachment fastener slot that extends along an entire length of the rail, where the length of the rail is within a longitudinal dimension that is orthogonal to the noted lateral dimension. The first rail side includes a first rail channel that extends along the entire length of the rail. The adapter includes a coupling section and a mounting flange. At least part of the coupling section is disposed within the first rail channel, while the mounting flange is disposed beyond the first rail channel such that the coupling section (while within the first rail channel) is located between the attachment fastener slot and the mounting flange in the lateral dimension. The mounting flange of the adapter includes first and second surfaces that are oppositely disposed and that are each substantially planar. The adapter includes a first projection that is adjacent to and protrudes relative to the first surface, with the first projection and the first surface facing or projecting in a common direction, and with the first projection being disposed between the rail and an entirety of the first surface in the lateral dimension.
A fifth aspect of the present invention is embodied by a rail assembly that is attachable to a building surface, and includes a rail (e.g., in the form of a one-piece body). The rail includes a rail top and a rail bottom that are spaced from one another in a vertical dimension, along with first and second rail sides that are spaced from one another in a lateral dimension. The rail top includes an attachment fastener slot that extends along an entire length of the rail, where the length of the rail is within a longitudinal dimension that is orthogonal to the noted lateral dimension. The first rail side includes a first rail channel that extends along the entire length of the rail, while the second rail side includes a second rail channel that also extends along the entire length of the rail. The rail further includes first, second, and third pockets. The first pocket has a closed perimeter and extends along the entire length of the rail, with a first rail bottom portion of the rail bottom defining a lower extreme of the first pocket, and with the first rail channel being adjacent to but isolated from the first pocket. The second pocket also has a closed perimeter and extends along the entire length of the rail, with a second rail bottom portion of the rail bottom defining a lower extreme of the second pocket, and with the second rail channel being adjacent to but isolated from the second pocket. The third pocket is disposed between the first pocket and the second pocket in the lateral dimension, and extends along the entire length of the rail. This attachment fastener slot extends to and intersects with the third pocket.
A sixth aspect of the present invention is embodied by a rail assembly that is attachable to a building surface, and includes a rail (e.g., in the form of a one-piece body). The rail includes a rail top, a rail bottom, a first rail side, a second rail side, and a pocket. The rail top includes an attachment fastener slot that extends along an entire length of the rail, where the length of the rail is within a longitudinal dimension. First and second cutouts intersect the attachment fastener slot to collectively define a rail mounting fastener access through the rail top.

The first rail side includes a first rail channel that extends along the entire length of the rail, while the second rail side includes a second rail channel that also extends along the entire length of the rail. The first and second rail sides are spaced from one another in a lateral dimension that is orthogonal to the noted longitudinal dimension. The pocket is located between the first rail channel and the second rail channel in the lateral dimension, is isolated from each of the first and second rail channels, and extends along the entire length of the rail. The attachment fastener slot extends to and intersects the pocket.
A number of feature refinements and additional features are separately applicable to each of above-noted of the present invention. These feature refinements and additional features may be used individually or in any combination in relation to each of the above-noted aspects. It should be appreciated that each of the noted aspects may be used in combination one or more of the other noted aspects.
A rail in accordance with the present invention may have a channel on at least one of its two sides (e.g., for interfacing with an adapter). A given rail channel of the rail may be disposed at least substantially parallel with an attachment fastener slot, including where each rail channel of the rail is disposed in at substantially parallel relation to one another. A rail may have first and second rail channels on the first and second rail sides, respectively. Such rail channels may be of a common configuration, may be the mirror image of one another, may be at least substantially parallel to one another, or any combination thereof. One embodiment has the rail being in the form of a one-piece body (e.g., of an integral construction; individual portions are not separately attached). One embodiment has the rail being of a low profile (e.g., where a ratio of a maximum width of the rail to a maximum height of the rail is at least about 2.6). A “width” dimension for the rail may correspond with a lateral dimension. A “longitudinal” dimension for the rail may correspond with a length of the rail and is orthogonal to the lateral dimension. A “vertical” dimension for the rail may correspond with a height of the rail, where the vertical dimension is orthogonal to a plane that contains the lateral and longitudinal dimensions.
The rail assembly in accordance with the present invention may utilize an adapter having both a coupling section and a mounting flange. One embodiment has this being an integral structure or in the form of a one-piece body (e.g., of an integral construction; individual portions are not separately attached). In any case, an adapter could be used with a rail that requires only a single rail channel (e.g., second, third, and fourth aspects), or could be used with a rail that requires a pair of rail channels (e.g., first, fifth, and sixth aspects). Multiple adapters may be interconnected with a first side of a rail, multiple adapters may be interconnected with a second side of a rail, or both (e.g., multiple adapters may be spaced along the length of the rail to for securement to spaced locations along the building surface, including where the location of each adapter corresponds with a standing seam, rib, or the like). In any case, an adapter may be slid along a corresponding rail channel of the rail to the desired/required position.
A first rail side of the rail may include a first rail channel that extends along the entire length of the rail, while a second rail side of the rail may include a second rail channel that also extends along the entire length of the rail. In such a case the rail assembly may be disposed in each of a first assembly configuration and a second assembly configuration in relation to such a rail and the above-noted adapter. The first assembly configuration entails a first coupling portion of the coupling section being slidably disposable in the first rail channel and the mounting flange being disposed beyond the first rail channel such that the first coupling portion (of the adapter) within the first rail channel (of the rail) is located between the mounting flange (of the adapter) and the attachment fastener slot (of the rail) in the lateral dimension. The second assembly configuration entails the first coupling portion of the coupling section being slidably disposable in the second rail channel and the mounting flange being disposed beyond the second rail channel such that the first coupling portion within the second rail channel is located between the mounting flange and the attachment fastener slot in the lateral dimension. That is, the rail and adapter may be configured such that the noted adapter may be disposed on the first rail side, or this same adapter may be disposed on the second rail side. Obviously the same adapter may only be interconnected with one of the first rail side and the second rail side at a given point in time and in the above-noted manner.
The rail assembly may utilize both a first mounting configuration and a second mounting configuration where the rail has at least one rail channel (e.g., a first rail channel, a second rail channel, or both) and where the rail assembly utilizes the above-noted adapter. The first mounting configuration entails a first coupling portion of the coupling section being disposed within the first rail channel in a first orientation relative to the rail, with the mounting flange being disposed beyond the first rail channel such that the first coupling portion (of the adapter) is located between the mounting flange (of the adapter) and the attachment fastener slot (of the rail) in the lateral dimension. The second mounting configuration entails a first coupling portion of the coupling section being disposed within the first rail channel in a second orientation relative to the rail, with the second orientation being different from the first orientation for the first mounting configuration, and with the mounting flange being disposed beyond the first rail channel such that the first coupling portion is located between the mounting flange and the attachment fastener slot in the lateral dimension.
Consider the case where the rail bottom (at least part of) is disposed on a reference plane. The mounting flange and this reference plane are separated by a first distance within the vertical dimension for the first mounting configuration, while the mounting flange and this reference plane are separated by a second distance within the vertical dimension for the second mounting configuration, with the first distance (associated with the first mounting configuration) being greater than the second distance (associated with the second mounting configuration), and where the measurement of the first and second distances from the noted reference plane may be to a common location on the mounting flange in the lateral dimension. That is, the rail and adapter may be configured such that the adapter may be installed on the first rail side in two different orientations (e.g., by inverting the adapter) and that changes the positioning of the mounting flange in the vertical dimension. One embodiment has the ratio of the first distance to the second distance being at least about 10. Obviously the same adapter may installed in only one of the two orientations at a given point in time and in the above-noted manner. Moreover, such an invertible adapter could be used with a rail having first and second oppositely disposed rail channels.
The rail assembly may be attached to a building surface using each of the above-noted first and second mounting configurations for the noted adapter. In the case of the first mounting configuration, a mounting device (of appropriate configuration) is attached to the building surface, the mounting flange of the adapter is disposed over/above the mounting device, and at least one fastener secures the mounting flange to this mounting device (an indirect attachment of the mounting flange to the building surface). In the case of the second mounting configuration, the mounting flange of the adapter may be disposed over/above a first rib or protrusion (e.g., a flat upper end of the first rib) of the building surface, and at least one fastener secures the mounting flange to this first rib by passing through both the mounting flange and the first rib and including a flat upper end of the first rib (a direct attachment of the mounting flange to the building surface).
Yet another option for securing a rail to a building surface is for the rail top to include first and second cutouts that each intersect with the attachment fastener slot so as to collectively define a rail mounting fastener access through the rail top. An effective diameter of such rail mounting fastener access is larger than a width of an entirety of the attachment fastener slot outside of this rail mounting fastener access. An attachment fastener pocket may be aligned with both the attachment fastener slot and the rail mounting fastener access. As such, a threaded rail mounting fastener may be directed entirely through the rail mounting fastener access, through the attachment fastener pocket, and through a corresponding portion of the rail bottom, for instance where a head of this threaded rail mounting fastener remains within the attachment fastener pocket (including in engagement with an interior surface of the rail), and where a shaft of this threaded mounting fastener extends through the corresponding portion of the rail bottom and into engagement with an underlying structure (e.g., a rib of a building surface, such as by this shaft of the threaded mounting fastener extending through a flat upper end of such a rib).
The coupling section for the above-noted adapter (coupling section and mounting flange) may include an inner coupling section and an outer coupling section. Consider the case where a rail channel for the rail (e.g., a first rail channel, a second rail channel) is defined by first and second rail lips that are separated by a slot that leads into the rail channel. The inner coupling section of the adapter may be disposed within a corresponding rail channel, and with the outer coupling section being spaced from the inner coupling section such that each of the first and second rail lips for this rail channel are captured between the inner coupling section and the outer coupling section of the adapter. The mounting flange extends from the outer coupling section at a location that is between first and second ends of the outer coupling section that are spaced from one another in the vertical dimension (e.g., the first and second ends of the outer coupling section may be characterized as the upper and lower extremes of the outer coupling section). The mounting flange is offset from each of the first and second ends of the outer coupling section in the vertical dimension, while the coupling section is located between the mounting flange and the attachment fastener slot in the lateral dimension.
The mounting flange for the above-noted adapter (coupling section and mounting flange) may include first and second surfaces that are oppositely disposed and that are each at least substantially planar. The adapter may include a first projection that is adjacent to and protrudes relative to the first surface, with the first projection and the first surface facing or projecting in a common direction, and with the first projection being disposed between the rail and an entirety of the first surface in the lateral dimension. One embodiment has the first surface of the mounting flange and an apex of the first projection being separated by a space of at least 0.050″ in the vertical dimension (e.g., to accommodate a seal between the mounting flange and the flat upper end of the first rib for the above-noted second mounting configuration, and where the first projection may engage the flat upper end of the first rib). One embodiment has the first surface of the mounting flange and an apex of the first projection being separated by a space of no more than about 0.055″ in the vertical dimension (e.g., to accommodate the noted seal).
One configuration for the rail utilizes a first pocket, a second pocket and a third pocket (e.g., the third pocket may correspond with the noted attachment fastener pocket). The first pocket has a closed perimeter and extends along the entire length of the rail. The second pocket also has a closed perimeter and extends along the entire length of the rail. The third pocket is disposed between the first pocket and the second pocket in the lateral dimension, and extends along the entire length of the rail. The first pocket may be located between the first rail side and the third pocket in the lateral dimension (e.g., a first wall may be disposed between the first pocket and the third pocket), while the second pocket may be located between the second rail side and the third pocket in the lateral dimension (e.g., a second wall may be disposed between the second pocket and the third pocket).
A first rail bottom portion of the rail bottom may define a lower extreme of the first pocket, a second rail bottom portion of the rail bottom may define a lower extreme of the second pocket, and a third rail bottom portion of the rail bottom may define a lower extreme of the third pocket. A lower surface of the third rail bottom portion (associated with the third pocket) may be recessed in a direction of the rail top (e.g., to accommodate receipt of a seal) relative to a lower surface of each of the first rail bottom portion (e.g., associated with the first pocket) and the second rail bottom portion (e.g., associated with the second pocket). At least part of an upper surface of each of the first rail bottom portion, the second rail bottom portion, and the third rail bottom portion may be convex relative to the first pocket, second pocket, and third pocket, respectively.
An attachment fastener pocket (e.g., the noted third pocket) may include upper and lower sections, with the attachment fastener slot extending to the upper section such that the upper section of the attachment fastener pocket is located between the attachment fastener slot and the lower section of the attachment fastener pocket in the vertical dimension. One embodiment has the upper section of the attachment fastener pocket and the lower section of the attachment fastener pocket being of different widths. The upper section of the attachment fastener pocket may be of a first width, while the lower section of the attachment fastener pocket may be of a second width, with the second width being of a smaller magnitude than the first width (e.g., the upper section of the attachment fastener pocket may be wider in the lateral dimension compared to the lower section of the attachment fastener pocket). Consider the case where an attachment fastener is movable along the attachment fastener slot in the longitudinal dimension and includes a first head, a threaded shaft, and a second head. At least one of the first and second heads may be rotatable relative to the shaft. The first head of the attachment fastener may be disposed above the rail top of the rail, the second head of the attachment fastener may include a flange and a body and may be disposed within the attachment fastener pocket, and the shaft of the attachment fastener may extend from the first head, through the attachment fastener slot, and at least to the second head. A flange for the second head of the attachment fastener may be disposed and retained within the upper section of the third pocket, while a body of the second head for the attachment fastener may be disposed within the lower section of the third pocket.
At least one attachment fastener may be slid along the attachment fastener slot to the desired/required position to interconnect a component with the rail (including where multiple attachment fasteners are spaced along the attachment fastener slot to interconnect a single component with the rail, to interconnect multiple components with the rail, or both). The rail top of the rail could also incorporate at least one groove, and a self-tapping screw could be directed through such a groove to attach an appropriate structure to the rail. For instance, a first groove may extend along the entire length of the rail in alignment with the noted first pocket, a second groove may extend along the entire length of the rail in alignment with the noted second pocket, or both. Such a rail thereby provides multiple options for securing a given structure to the rail (e.g., using an attachment fastener and the noted attachment fastener slot; using one or more self-tapping screws that extend through the rail top within a corresponding groove).
Any feature of any other various aspects of the present invention that is intended to be limited to a “singular” context or the like will be clearly set forth herein by terms such as “only,” “single,” “limited to,” or the like. Merely introducing a feature in accordance with commonly accepted antecedent basis practice does not limit the corresponding feature to the singular (e.g., indicating that a rail assembly includes/utilizes “a rail channel” alone does not mean that the rail assembly includes/utilizes only a single rail channel). Moreover, any failure to use phrases such as “at least one” also does not limit the corresponding feature to the singular (e.g., indicating that a rail assembly includes/utilizes “a rail channel” alone does not mean that the rail assembly includes only a single rail channel). Use of the phrase “at least generally” or the like in relation to a particular feature encompasses the corresponding characteristic and insubstantial variations thereof (e.g., indicating that a surface is at least generally/substantially flat encompasses the surface actually being planar or flat). Finally, a reference of a feature in conjunction with the phrase “in one embodiment” does not limit the use of the feature to a single embodiment.

A recess 70 (e.g., a curved or arcuate surface that extends along the length of the rib 54) is disposed directly below the projection 68. In one embodiment, the distance between the recesses 60, 70 is at least about ½ inch (measured within the interior 76). In any case, a transition section 72 of the second sidewall 66 extends from the recess 70 at least toward the corresponding base section 78 of the panel 52. In the illustrated embodiment, the transition section 72 is a flat surface that extends all the way from the recess 70 to the corresponding base section 78.

The mounting body 102 for the mounting device 100 includes a base 104, a first leg 112, and a second leg 122 that collectively define a rib receptacle 150. The base 104, first leg 112, and second leg 122 are retained in a fixed position relative to one another. A reference plane 152 extends through this rib receptacle 150, and is oriented to contain both the height dimension and the length dimension of the rib 54 when the mounting device 100 is installed on the rib 54 (e.g., the reference plane 152 may be characterized as extending along the pitch P of the roofing surface 50a and perpendicularly to a reference plane that contains the base section(s) 78 of the panels 52 (or oriented perpendicularly to the pitch P)). A reference plane 154 may be positioned above the mounting device 100 and is perpendicular to the reference plane 152.
The base 104 of the mounting body 102 may be characterized as being disposed in overlying relation to the upper end 74 of the rib 54 when the mounting device 100 is installed on the rib 54. As shown in
The first leg 112 of the mounting body 102 may be characterized as extending from one side of the base 104, while the second leg 122 of the mounting body 102 may be characterized as extending from an opposite side of the base 104. In any case, the first leg 112 is disposed alongside at least an upper portion of the first sidewall 56 of the rib 54 when the mounting device 100 is installed on the rib 54. An included angle between the first leg 122 and the lower section 108 of the base 104 (measured within the rib receptacle 150) may be greater than 90° or in the form of an obtuse angle.
The first leg 112 of the mounting body 102 includes a free end 114 having a projection 116 (e.g., the first leg 112 may be characterized as a cantilever—being supported on only one end thereof (at the base 104)). The projection 116 may be defined by an arcuate or curved surface, and defines a pocket 118 on the inside surface of the first leg 112. A pad 120 having a higher coefficient of friction than the mounting body 102 may be positioned along the pocket 118, and may extend along the inside surface of the first leg 112 in the direction of the base 104 (e.g.,
The projection 116 for the first leg 112 may be characterized as extending at least generally in the direction in which the second leg 122 of the mounting body 102 is spaced from the first leg 112 of the mounting body 102 (or toward the reference plane 152), as extending at least generally in the direction in which the base 104 is spaced from the free end 114 of the first leg 112 (or toward the reference plane 154), or both. The projection 116 may be characterized as “pointing” both at least generally upwardly (or toward the reference plane 154) and toward the noted reference plane 152 when the mounting device 100 in installed on a rib 54 of the building/roofing surface 50a. In any case, the projection 116 is disposed within the recess 60 on the first sidewall 56 of the rib 54 (and directly below the projection 58 on the first sidewall 56 of the rib 54) when the mounting device 100 in installed on the rib 54 of the building/roofing surface 50a. Contact between the first leg 112 of the mounting body 102 and the rib 54 of the building/roofing surface 50a may be limited to the projection 116/pocket 118 and the recess 60/projection 58 (e.g., the remainder of the first leg 112 the mounting body 102 may be maintained in spaced relation to the rib 54).
The second leg 122 of the mounting body 102 is disposed alongside at least an upper portion of the second sidewall 66 of the rib 54 when the mounting device 100 is installed on the rib 54. A first section 124 of the second leg 122 extends from the base 104 in one orientation, while a second section 126 of the second leg 122 extends from the first section 124 in a different orientation. An included angle between the first section 124 of the second leg 122 and the lower section 108 of the base 104 (measured within the rib receptacle 150) may be greater than 90° or in the form of an obtuse angle. The second section 126 of the second leg 122 may be characterized as being disposed at least generally parallel with the reference plane 152.
The second leg 122 of the mounting body 102 is actually spaced from the second sidewall 66 of the rib 54 when the mounting device 100 is fully installed on the rib 54—no portion of the second leg 122 of the mounting body 102 contacts the second sidewall 66 of the rib 54 at this time. Instead, the insert 160 is used to contact the second sidewall 66 of the rib 54. The second leg 122 the mounting body 102 includes a number of features to accommodate the insert 160. One is that the inside or interior surface of the second leg 122 (that projects toward/interfaces with the rib receptacle 150) may be characterized as including an insert receptacle 128. An upper surface 130 and a side surface 132 collectively define this insert receptacle 128. Generally, the insert 160 may be positioned against the side surface 132 of the second leg 122 that collectively defines the insert receptacle 128 with the upper surface 130 (the insert 160 could also be positioned against the upper surface 130 (
The second leg 122 of the mounting body 102 may be characterized as a cantilever in that it is supported on only one end thereof—at its intersection with the base 104 (i.e., the second leg 122 includes the noted free end 134, which is spaced from the base 104). A rounded portion 136 is included on the free end 134 of the second leg 122. This rounded portion 136 defines at least part of the boundary for the recess 138 (which may receive the lip 179 of the insert 160). Moreover, this rounded portion 136 may be used to reposition the insert 160 during installation of the mounting device 100 on the rib 54.
A pair of threaded holes 140 extend completely through the second section 126 of the second leg 122 of the mounting body 102. The length dimension of each threaded hole 140 is identified by reference numeral 142, and is oriented orthogonally to the reference plane 152 in the illustrated embodiment. Each threaded hole 140 for the second leg 122 receives a single clamping fastener 180. Any appropriate number of threaded holes 140 may be incorporated by the second section 126 of the second leg 122 (including more than two threaded holes 140). Generally, one or more clamping fasteners 180 are directed through the second section 126 of the second leg 122, engage the insert 160, and move the insert 160 away from the second leg 122 when installing the mounting device 100 on a rib 54. As the insert 160 is engaged with the second sidewall 66 of the rib 54, this motion of the insert 160 may compress the rib 54 to a degree (in a lateral dimension coinciding with the dimension in which the first sidewall 56 of the rib 54 is spaced from its corresponding second sidewall 66).
Additional views for the insert 160 of the mounting device 100 are presented in
The projection 164 for the insert 160 may be characterized as extending at least generally in the direction in which the first leg 112 of the mounting body 102 is spaced from the second leg 122 of the mounting body 102 (or toward the reference plane 152), as extending at least generally in the direction in which the base 104 is spaced from the free end 134 of the second leg 122 (or toward the reference plane 154), or both. The projection 164 may be characterized as “pointing” both at least generally upwardly (or toward the reference plane 154) and toward the reference plane 152 when the mounting device 100 in installed on a rib 54 of the building/roofing surface 50a. In any case, the projection 164 is disposed within the recess 70 on the second sidewall 66 of the rib 54 (and directly below the projection 68 on the second sidewall 66 of the rib 54) when the mounting device 100 in installed on the rib 54 of the building/roofing surface 50a. Contact between the insert 160 and the rib 54 of the building/roofing surface 50a (when the mounting device 100 is completely installed on the rib 54) may be limited to the projection 164/pocket 166 and the recess 70/projection 68 (e.g., the remainder of the insert 160 may be maintained in spaced relation to the rib 54).
The insert 160 includes a number of additional features that facilitate installation of the mounting device 100. The insert 160 includes a first or alignment surface 162 (which may extend along the entire length of the insert 160). Prior to rotating or pivoting the mounting body 102 onto the rib 54 (to capture the insert 160 within the rib receptacle 150 of the mounting body 102), the alignment surface 162 of the insert 160 may be positioned against the transition section 72 on the second sidewall 66 of the rib 54 (adjacent to the recess 70).
The noted pocket 166 is located between the second projection 164 of the insert 160 and a third projection 168. This pocket 166 may be characterized as a concave surface on the exterior of the insert 160, and nonetheless provides an interface for the projection 68 on the second sidewall 66 of the rib 54 (e.g., at least part of this projection 68 on the second sidewall 66 of the rib 54 may be captured within this pocket 166). Both the pocket 166 and the third projection 168 may extend along the entire length of the insert 160.
A fastener receptacle surface 172 is on the perimeter or exterior of the insert 160, and is disposed at least generally opposite of the second projection 164. A plurality of clamping fastener receptacles 174 are formed on the fastener receptacle surface 172 (two in the illustrated embodiment) and extend into the interior of the insert 160. There should be one clamping fastener receptacle 174 for each clamping fastener 180 to be used by the mounting device 100. A tapered surface 170 extends from the fastener receptacle surface 172 to the third projection 168. The tapered surface 170 and the alignment surface 162 are disposed in the same general orientation (e.g., having a common sign for their respective slopes, although the magnitude of their respective slopes may differ), but are not parallel to each other in the illustrated embodiment. The tapered surface 170 also may have a slight curvature (e.g., convexly-shaped).
Each clamping fastener receptacle 174 may be characterized as a “blind hole”—no clamping fastener receptacle 174 extends completely through the insert 160. In this regard, each clamping fastener receptacle 174 includes a closed end or base 176 (located within the interior of the insert 160) and an annular sidewall 178 that extends from this base 176 to the fastener receptacle surface 172 of the insert 160. The centerline of each clamping fastener receptacle 174 (e.g., coinciding with the above-noted length dimension 142 for the threaded holes 140 through the second leg 122 of the mounting body 102) may be at least generally aligned with the second projection 164 of the insert 160 (
Panels having different hollow rib configurations may be used with the mounting device 100 of
Another example of a panel configuration is commonly referred to as a trapezoidal rib panel (e.g., formed from an appropriate metal alloy). A representative trapezoidal rib panel is illustrated in
Each trapezoidal rib 204 may include an upper rib wall 206 in the form of a flat or planar surface. Each trapezoidal rib 204 may also include a pair of sides 208a, 208b. The sides 208a, 208b are spaced from each other and are disposed in non-parallel relation. Typically the sides 208a, 208b of a trapezoidal rib 204 will be the mirror image of each other in relation to their respective orientations. In any case, the upper rib wall 206 and the two sides 208a, 208b collectively define a hollow interior or open space 210 for the trapezoidal rib 204.
One embodiment of a mounting device that is adapted for use with trapezoidal rib panels is illustrated in
The mounting bracket 220 includes an upper wall or mounting surface 224 and a pair of side legs 228a, 228b that extend downwardly from the upper wall 224 when the mounting bracket 220 is installed on a trapezoidal rib 204. The upper wall 224 is the uppermost portion of the mounting bracket 220 when positioned on a trapezoidal rib 204, extends between a pair of open ends 222 of the mounting bracket 220, and is in the form of a single flat surface (rectangular in the illustrated embodiment). In one embodiment, the upper wall 224 provides a flat surface area, defined by a perimeter which in turn defines an area of at least 2.5 inches2, to provide an appropriate surface for supporting attachments of any appropriate type. In this regard, the upper wall 224 includes a mounting hole 226 that extends completely through this upper wall 224.
A single mounting hole 226 is shown in the illustrated embodiment (e.g., located equidistantly from the two ends 222, although such may not be required in all instances). Multiple mounting holes could be incorporated by the upper wall 224 if required by a particular application or if otherwise desired. Each given mounting hole 226 may be threaded or unthreaded. In the case of a threaded mounting hole 226, a threaded attachment fastener (e.g., a threaded stud or bolt) could have its threads engaged with the threads of a particular mounting hole 226 to secure at least one attachment relative to the mounting bracket 220. An attachment fastener could also extend through a particular mounting hole 226 without having any type of threaded engagement with the mounting bracket 220, and a nut could be threaded onto an end of this attachment fastener to secure at least one attachment relative to the mounting bracket 220.
Any appropriate configuration may be utilized by each mounting hole 226 through the upper wall 224 of the mounting bracket 220. Representative configurations for each mounting hole 226 include circular or round. A given mounting hole could also be in the form of a slot that is elongated in the dimension of the spacing between the two ends 222. Such an elongated slot allows the position of an attachment fastener to be adjusted relative to the mounting bracket 220, for instance after the mounting bracket 220 has already been anchored relative to a building surface and which may be of significant benefit for at least certain installations on a building surface (e.g., an attachment fastener can be moved to any position along the length of the mounting slot, and can then be secured relative to the mounting bracket 220 by the above-noted nut).
The bracket side legs 228a, 228b are spaced from one another, and will typically be the mirror image of each other with regard to their respective orientations (e.g., an included angle between the underside of the upper wall 224 and the inside surface 230 each of the side legs 228, 228b being greater than 90° as shown). The bracket side leg 228a is positioned along an upper portion of the side 208a of a trapezoidal rib 204 (
The mounting bracket 220 further includes a pair of rib offsetting members that are disposed within a hollow interior 248 of the mounting bracket 220 (e.g., the partially enclosed space collectively defined by the upper wall 224 and the pair of bracket side legs 228a, 228b). Only the rib offsetting member 246a for the side leg 228a being shown in
The underside of each rib offsetting member for the mounting bracket 220 is positioned on the upper rib wall 206 of the trapezoidal rib 204 to dispose the upper wall 224 of the mounting bracket 220 above and in spaced relation to the upper rib wall 206 of the trapezoidal rib 204 (
At least one fastener extends through the bracket side leg 228a (two being accommodated in the illustrated embodiment), and terminates within the hollow interior 210 of the trapezoidal rib 204 when securing the mounting bracket 220 to a trapezoidal rib 204 (e.g.,
Another example of a panel configuration is commonly referred to as a corrugated panel (e.g., formed from an appropriate metal or metal alloy). A representative corrugated panel is illustrated in
A corrugated panel 302 is defined by a plurality of panel crowns 304 and a plurality of panel valleys 308. In the illustrated embodiment, a panel valley 308 is disposed between each adjacent pair of panel crowns 304. The corrugated panel 302 may be of a sinusoidal or “sine wave” configuration in an end view. In any case, typically a corrugated panel 302 will be installed in a roofing application such that the length dimension of its panel crowns 304 and panel valleys 308 each extend along the roof pitch (e.g., the elevation of each panel crown 304 and each panel valley 308 may continually change proceeding along its length dimension). A “panel crown” 304 of a corrugated panel 302 may also be referred to as a “rib” or “the high.” A “panel valley” 308 of a corrugated panel 302 may also be referred to as a “trough” or “the low.”
One embodiment of a mounting device that is adapted for use with corrugated panels is illustrated in
The mounting bracket 310 includes what may be characterized as a valley section 314 that is positioned above a panel valley 308 when the mounting bracket 310 is positioned on a corrugated panel 302 (
A single mounting hole 318 is shown in the illustrated embodiment (e.g., located equidistantly from the two ends 312, although such may not be required in all instances). Multiple mounting holes could be incorporated by the upper wall 316 if required by a particular application or if otherwise desired. Each given mounting hole 318 may be threaded or unthreaded. In the case of a threaded mounting hole 318, a threaded attachment fastener (e.g., a threaded stud or bolt) could have its threads engaged with the threads of a particular mounting hole 318 to secure at least one attachment relative to the mounting bracket 310. An attachment fastener could also extend through a particular mounting hole 318 without having any type of threaded engagement with the mounting bracket 310, and a nut could be threaded onto an end of this attachment fastener (this end being disposed within an open space 342 of the mounting bracket 310, discussed below) to secure at least one attachment relative to the mounting bracket 310.
Any appropriate configuration may be utilized by each mounting hole 318 through the upper wall 316 of the mounting bracket 310. Representative configurations for each mounting hole 318 include circular or round. A given mounting hole could also be in the form of a slot that is elongated in the dimension that the ends 312 are spaced from one another. Such an elongated slot allows the position of an attachment fastener to be adjusted relative to the mounting bracket 310, for instance after the mounting bracket 310 has already been anchored relative to a building surface and which may be of significant benefit for at least certain installations on a building surface (e.g., an attachment fastener can be moved to any position along the length of the mounting slot, and can then be secured relative to the mounting bracket 310 by the above-noted nut).
The above-noted bracket ends 312 may be characterized as being spaced along a length dimension of the mounting bracket 310 (e.g., the spacing between the bracket ends 312 may define the length of the mounting bracket 310). When the mounting bracket 310 is positioned on a corrugated panel 302 (e.g.,
The mounting bracket 310 further includes a pair of bracket legs 320a, 320b. The bracket leg 320a extends from one side of the valley section 314 (the upper wall 316 in the illustrated embodiment), while the other bracket leg 320b extends from the opposite side of the valley section 314 (the upper wall 316 in the illustrated embodiment). Each bracket leg 320a, 320b may be characterized as extending both downwardly and away from its corresponding side of the valley section 314 when the mounting bracket 320 is in an upright position. Another characterization is that the bracket leg 320a extends from the valley section 314 at least generally in the direction of one panel crown 304 of a corrugated panel 302 on which the mounting bracket 310 is positioned, while the bracket leg 320b extends from the valley section 314 at least generally in the direction of another panel crown 304 of a corrugated panel 302 on which the mounting bracket 310 is positioned.
The mounting bracket 310 further includes a third bracket leg 334a that extends from the first bracket leg 320a, along with a fourth bracket leg 334b that extends from the second bracket leg 320b. The bracket legs 334a, 334b may converge to define a panel valley engagement section 332. Stated another way, the intersection of the third bracket leg 334a and the fourth bracket leg 334b may define a panel valley engagement section 332 for the mounting bracket 310. This defines an included angle 336 between the third bracket leg 334a and the fourth bracket leg 334b. In the illustrated embodiment, the magnitude of this included angle 336 is less than 90°.
The panel valley engagement section 332 includes what may be characterized as a panel valley interface surface 338—the surface of the panel valley engagement section 332 that interfaces with a panel valley 308 of a corrugated panel 302 when the mounting bracket 310 is positioned on such a corrugated panel 302. In the illustrated embodiment, the panel valley interface surface 338 is convex or of a “rounded” configuration.
The upper wall 316 of the mounting bracket 310 may be characterized as being disposed in overlying relation to the panel valley engagement section 332. The upper wall 316 may also be characterized as being separated from the panel valley engagement section 332 by an open space 342 (the open space 342 being within or part of the hollow interior of the mounting bracket 310). In one embodiment, the vertical extent of this open space 342 (i.e., “vertical” being when the mounting bracket 310 is disposed in an upright position, and also coinciding with the dimension that is orthogonal/perpendicular to the pitch of a roofing defined by a corrugated panel 302 on which the mounting bracket 310 is positioned) is at least about 1 inch. That is, the underside of the upper wall 316 may be separated from the panel valley engagement section 332 by a distance of at least about 1 inch in at least one embodiment.
The mounting hole 318 in the upper wall 316 may be characterized as being aligned in the vertical dimension with the panel valley engagement section 332 when the mounting bracket 310 is disposed in an upright position. The open space 342 also therefore exists between the mounting hole 318 and the panel valley engagement section 332 (e.g., the mounting hole 318 may be aligned with the open space 342 in the vertical dimension; the open space 342 may be characterized as being below the mounting hole 318). As such, an attachment fastener may be directed within the mounting hole 318, may extend through the upper wall 316, and may terminate within the open space 342. That is, such an attachment fastener could extend beyond the underside of the upper wall 316 a distance of at least about 1″ in the noted embodiment before contacting another portion of the mounting bracket 310 (e.g., the side of the panel valley engagement section 332 that is opposite of the panel valley interface surface 338).
The mounting bracket 310 also includes a pair of panel crown engagement sections 324. Initially, each panel crown engagement section 324 is offset or spaced in the vertical dimension from the panel valley engagement section 332. Stated another way and when the mounting bracket 314 is disposed in an upright position, the panel valley engagement section 332 is disposed at a different elevation than each panel crown engagement section 324 (each panel crown engagement section 324 being disposed at a higher elevation than the panel valley engagement section 332). Moreover, the panel valley engagement section 332 is offset from each panel crown engagement section 324 in a lateral dimension that is orthogonal to the above-noted vertical dimension.
The first bracket leg 320a extends between one of the panel crown engagement sections 324 and the valley section 314. Similarly, the second bracket leg 320b extends between the other panel crown engagement section 324 and the valley section 314. One panel crown engagement section 324 of the mounting bracket 310 may be positioned on one panel crown 304 of a corrugated panel 302 (located on one side of a panel valley 308 engaged by the panel valley engagement section 332), while the other panel crown engagement section 324 may be positioned on a different panel crown 304 of a corrugated panel 302 (located on the opposite side of a panel valley 308 engaged by the panel valley engagement section 332). In the illustrated embodiment, each panel crown engagement section 324 engages the adjacent-most panel crown 304 to the panel valley 308 contacted by the panel valley engagement section 332 of the mounting bracket 310, although such may not be required in all instances.
Each panel crown engagement section 324 may engage a panel crown 304 of a corrugated panel 302 on which the mounting bracket 310 is positioned. In the illustrated embodiment, there may be two discrete zones of contact between each panel crown engagement section 324 and its corresponding panel crown 304. In this regard, each panel crown engagement section 324 may include a pair of rails, projections, or dimples 328 that may extend between the two ends 312 of the mounting bracket 310. If the spacing between the two ends 312 is characterized as the length dimension for the mounting bracket 310, each projection 328 may be characterized as extending along at least part of the length of the mounting bracket 310. Each projection 328 may be convex or rounded where engaged with a corresponding panel crown 304.
Each projection 328 may provide a discrete zone of contact (e.g., extending along a line or axial path) between the corresponding panel crown engagement section 324 and its corresponding panel crown 304 of a corrugated panel 302. Generally, the use of the projections 328 reduces the area of contact between the mounting bracket 310 and a panel crown 304 of a corrugated panel 302, which should reduce the potential for capillary entrapment (e.g., should reduce the potential of water “wicking” into interfacing surfaces of the mounting bracket 310 and a corrugated panel 302, which could lead to the development of corrosion and premature failure of a building surface 300 incorporating such a corrugated panel 302).
A gasket pocket or receptacle 326 is defined between the projections 328 on each of the panel crown engagement sections 324. At least one bracket fastener hole 330 extends through each of the panel crown engagement sections 324 and intersects the corresponding gasket pocket 326. In the illustrated embodiment, there are two bracket fastener holes 330 that are aligned with the gasket pocket 326 for each of the panel crown engagement sections 324. Any appropriate number of bracket fastener holes 330 may be utilized by each panel crown engagement section 324. In one embodiment, each bracket fastener hole 330 is un-threaded. An appropriate bracket fastener (e.g., threaded screw, rivet) may be directed through each bracket fastener hole 330 and through the aligned portion of a corrugated panel 302 to secure the mounting bracket 310 relative to the corrugated panel 302. Various options in this regard will be discussed in more detail below in relation to
A gasket of any appropriate type (e.g., an EPDM gasket—not shown) may be disposed within each of the gasket pockets 326. The projections 328 on each panel crown engagement section 324 should confine the corresponding gasket therebetween. In one embodiment, each gasket that is positioned within a gasket pocket 326 is thicker than the depth of its corresponding gasket pocket 326 prior to the mounting bracket 310 being secured relative to a corrugated panel 302. As such, the gaskets may be compressed between the mounting bracket 310 and the corresponding panel crown 304 as the mounting bracket 310 is secured relative to a corrugated panel 302. The above-described projections 328 may also provide the function of reducing the potential of these gaskets being “over-compressed” while securing the mounting bracket 310 relative to a corrugated panel 302.
Each gasket may be installed within its corresponding gasket pocket 326 prior to installing the mounting bracket 310 on a corrugated panel 302. Any appropriate way of maintaining a gasket within its corresponding gasket pocket 326 may be utilized (e.g., by being press fit within the corresponding gasket pocket 326; adhering a gasket 326 to an inner surface of its corresponding gasket pocket 326). When the mounting bracket 310 is secured relative to a corrugated panel 302, each gasket may compress to bring the above-noted projections 328 into contact with the corresponding panel crown 304 of the corrugated panel 302. However, the projections 328 should still at least substantially confine the corresponding gasket within its corresponding gasket pocket 326, and furthermore should reduce the potential for the gaskets being over-compressed during installation as noted.
A panel assembly may be defined by an edge portion of one panel being interconnected with an edge portion of an adjacent panel to define a standing seam, as noted above. Various types of standing seam configurations exist. One embodiment of a standing seam panel assembly is illustrated in

The right edge section 408 includes a sidewall 412b that extends upwardly when the corresponding panel 402 is horizontally disposed (e.g., disposed orthogonal to the pitch of the corresponding roofing surface; extending away from a reference plane that contains the main body of the corresponding panel 402), along with an end section 410b that extends downwardly when the corresponding panel 402 is horizontally disposed (extending toward a reference plane that contains the main body of the corresponding panel 402). The sidewall 412b and the end section 410b of the right edge section 408 are interconnected by an arcuate section, and with the end section 410b being disposed “outwardly” of the sidewall 412b in a lateral dimension. In the illustrated embodiment, the spacing between the sidewall 412b and its corresponding end section 410b is larger than the spacing between the sidewall 412a and its corresponding end section 410a.
Each panel 402 further includes a first lateral edge (the horizontal edge shown in
One embodiment of a mounting device that may be installed on a standing seam of a panel assembly (e.g., standing seam 404 shown in
One or more threaded holes 446 extend from at least one of the side surfaces 426 and to the slot 440 for securing the mounting device 420 to a corresponding standing seam. In the illustrated embodiment, multiple threaded holes 446 extend from each of the side surfaces 426 of the mounting device 420 and to the slot 440. Each threaded hole 446 on one of the slot sidewalls 444 is disposed in opposing relation to a threaded hole 446 on the other slot sidewall 444. However, the mounting device 420 could be configured such that only one of the slot sidewalls 444 has one or more threaded holes 446. Moreover, the mounting device 420 could be configured such that each threaded hole 446 on one slot sidewall 444 is not aligned with a threaded hole 446 on the other slot sidewall 444. One or more seam fasteners may be directed through a threaded hole 446 of the mounting device 420 and into the slot 440 to engage the standing seam and secure the same against the opposing slot sidewall 444. In one embodiment, each seam fastener only interfaces with an exterior surface of the standing seam. For instance, the end of the seam fastener that interfaces with the standing seam may be convex, rounded, or of a blunt-nosed configuration to provide a desirable interface with the standing seam.
The upper surface 422 of the mounting device 420 of
As should be appreciated, the elongated mounting slot 450 allows for adjustment of the location of an attachment fastener 470 relative to the mounting device 420, which may be of significant benefit for at least certain installations on a building/roofing surface. Even after the mounting device 420 is anchored relative to the building/roofing surface in the above-noted manner, the attachment fastener 470 can be moved to any position along the length of the mounting slot 450. The length of the mounting slot 450 accommodates a significant number of different positions of the attachment fastener 470 relative to the mounting device 420—the attachment fastener 470 may assume a number of different positions between the two ends 428 of the mounting device 420 and that is accommodated by the elongated mounting slot 450.
The attachment fastener 470 in the illustrated embodiment is in the form of bolt having a threaded shaft 472 that is fixed relative to and extends from a bolt head 474. The bolt head 474 is positioned on/above the upper surface 422 of the mounting device 420, while the threaded shaft 472 extends through the mounting slot 450 for engagement with a nut that is positioned within the receptacle 460. An attachment that is positioned between the bolt head 474 and the upper surface 422 of the mounting device 420 may then be anchored relative to the mounting device 420 by the attachment fastener 470. It should be appreciated that the bolt head 474 could instead be positioned in the receptacle 460, for instance by extending the mounting slot 450 to the two ends 428 of the mounting device 420. In any case, the shaft 472 would extend upwardly through the mounting slot 450 in this instance and a nut could be located externally of the mounting device 420 to secure an attachment relative to the mounting device 420.
One embodiment of a rail that may be secured relative to a building/roofing surface, and to which an attachment may be secured, is illustrated in
The rail 540 shown in
The rail top 560 includes an attachment fastener slot 562 that extends along the entire length of the rail 540 (the attachment fastener slot 562 extends from the rail end 610a to the rail end 610b). This attachment fastener slot 562 extends in the vertical dimension 546 to an open, interior space of the rail 540 that will be discussed in more detail below (third pocket 628). A first rail top section 564a is positioned on one side of the attachment fastener slot 562, while a second rail top section 564b is positioned on the opposite side of the attachment fastener slot 562. A first groove 566a extends along the entire length of the rail 540 on the rail top section 564a, while a second groove 566b extends along the entire length of the rail 540 on the rail top section 564b (each extends the entire distance from rail end 610a to rail end 610b). One or more appropriate fasteners, such as a self-tapping or self-drilling screws, may be directed through the first rail top section 564a within the first groove 566a (for termination within a first pocket 624, discussed in more detail below) and/or may be directed through the second rail top section 564b within the second groove 566b (for termination within a second pocket 626, discussed in more detail below) to secure an attachment relative to the rail 540. The attachment option may be employed in appropriate circumstances, including for the case of shorter rails 540. In any case and for the illustrated embodiment, the rail top sections 564a, 564b are the mirror image of one another. Each of the rail top sections 564a, 564b may be of any appropriate width, although typically the rail top sections 564a, 564b will be of a common width that is of a sufficient magnitude for the particular attachment application.
The first rail side 600a includes a first rail slot 602a and a corresponding first rail channel 604a that each extend along the entire length of the rail 540 (the first rail slot 602a and channel 604a each extend from the rail end 610a to the rail end 610b). The first rail channel 604a is defined by corresponding portions of the rail top 560 and rail bottom 580, along with a pair of rail lips 606a, 606b that are spaced from a first interior wall 622a that extends from the first rail top section 564a to the rail bottom 580 (the rail lips 606a and 606b on the first rail side 600a, along with the first interior wall 622a, all extend the entire length of the rail 540). The first rail side slot 602a may be characterized as being defined by the spacing between the rail lips 606a, 606b (on the first rail side 600a) in the vertical dimension 546, and which provides access to the first rail channel 604a. The first rail channel 604a may be characterized as being at least generally C-shaped.
The second rail side 600b includes a second rail slot 602b and a corresponding second rail channel 604b that each extend along the entire length of the rail 540 (the second rail slot 602b and channel 604b each extend from the rail end 610a to the rail end 610b). The second rail channel 604b is defined by corresponding portions of the rail top 560 and rail bottom 580, along with a pair of rail lips 606a, 606b that are spaced from a second interior wall 622b that extends from the second rail top section 564b to the rail bottom 580 (the rail lips 606a and 606b on the second rail side 600b, along with the second interior wall 622b, all extend the entire length of the rail 540). The second rail side slot 602b may be characterized as being defined by the spacing between the rail lips 606a, 606b (on the second rail side 600b) in the vertical dimension 546, and which provides access to the second rail channel 604b. The second rail channel 604b may be characterized as being at least generally C-shaped.
The rail bottom 580 is again spaced from the rail top 560 in the vertical dimension 546 for the rail 540, and may be characterized as including a first rail bottom portion 582a, a second rail bottom portion 582b, and a third rail bottom portion 582c, with the third rail bottom portion 582c being located between the first rail bottom portion 582a and the second bottom rail portion 582b in the lateral dimension 542 for the rail 540. The first rail bottom portion 582a is defined by an upper surface 584a and a bottom surface 586a that are spaced from one another in the vertical dimension 546 to define a thickness for the corresponding portion of the rail bottom 580, with at least part of the upper surface 584a being convex relative to the first pocket 624 (e.g., a portion thereof that extends from the interior wall 620a). The second rail bottom portion 582b is defined by an upper surface 584b and a bottom surface 586b that are spaced from one another in the vertical dimension 546 to define a thickness for the corresponding portion of the rail bottom 580, with at least part of the upper surface 584b being convex relative to the second pocket 628 (e.g., a portion thereof that extends from the interior wall 620b). The third rail bottom portion 582c is defined by an upper surface 584c and a bottom surface 586c that are spaced from one another in the vertical dimension 546 to define a thickness for the corresponding portion of the rail bottom 580, with at least part of the upper surface 584c being convex relative to the third pocket 624 (the entirety of the upper surface 584c being convex relative to the third pocket 624 in the illustrated embodiment). The bottom surface 586c of the third rail bottom portion 582c is spaced in the direction of the rail top 560 relative to both the first rail bottom portion 582a and the second rail bottom portion 582b to define a rail bottom recess 588. In the illustrated embodiment, the rail bottom recess 588 is centrally disposed in the lateral dimension 542 for the rail 540. An appropriate seal or gasket may be positioned within this rail bottom recess 588.
The rail 540 further includes a third interior wall 620a and a fourth interior wall 620b that each extend from the rail top 560 (more specifically, the first rail top section 564a and the second rail top section 564b, respectively) to the rail bottom 580. The first interior wall 622a and the third interior wall 620a are spaced from one another in the lateral dimension 542 for the rail 540, with a first pocket 624 being defined by these walls 622a, 620a and corresponding portions of the rail top 560 (more specifically the first rail top section 564a) and the rail bottom 580. The first pocket 624 is defined by a closed perimeter and extends the entire length of the rail 540 from the rail end 610a to the rail and 610b. The second interior wall 622b and the fourth interior wall 620b are similarly spaced from one another in the lateral dimension 542 for the rail 540, with a second pocket 626 being defined by these walls 622b, 620b and corresponding portions of the rail top 560 (more specifically the second rail top section 564b) and the rail bottom 580. The second pocket 626 is defined by a closed perimeter and extends the entire length of the rail 540 from the rail end 610a to the rail end 610b.
The first pocket 624 is isolated from a third pocket 628 by the third interior wall 620a, while the second pocket 626 is isolated from this same third pocket 628 by the fourth interior wall 620b, with the third interior wall 620a being spaced in the lateral dimension 542 from the fourth interior wall 620b. A lower extreme of the third pocket 628 is closed by the third rail bottom portion 582c, and as such the rail bottom recess 588 is aligned with the third pocket 628 in the vertical dimension 546 for the rail 540. The third pocket 628 is also aligned in the vertical dimension 546 with the attachment fastener slot 562, and includes an upper section 630 and a lower section 632. The upper section 630 is wider than both the attachment fastener slot 562 and the lower section 632, and furthermore is located between the attachment fastener slot 562 and the lower section 632 in the vertical dimension 546 for the rail 540.
In summary, features of the rail 540 include: a first rail top section 564a and associated first groove 566a; a second rail top section 564b and associated second groove 566b; an attachment fastener slot 562; a first rail side 600a and an associated first rail side slot 602a and first rail channel 604a; a second rail side 600b and an associated second rail side slot 602b and second rail channel 604b; a first pocket 624 and associated interior walls 622a and 620a; a second pocket 626 and associated interior walls 622b and 620b; a third pocket 628 and associated interior walls 620a and 620b; a first rail bottom portion 582a; a second rail bottom portion 582b; and a third rail bottom portion 582c. Each of these features of the rail 540 extend the entire length of the rail 540, namely from the rail end 610a to the rail and 610b.
The flange 694 for the attachment fastener 690 has a larger effective diameter than the head 692, and is disposed within the upper section 630 of the third pocket 628. The shaft 696 is fixed relative to each of the head 692 and the flange 694, and extends upwardly through the attachment fastener slot 562 (e.g., for engagement with an attachment, such as by passing through an aperture of any type in the attachment). A nut (e.g., nut 698, shown in
The flange 700 for the nut 698 has a larger effective diameter than the nut body, and is disposed within the upper section 630 of the third pocket 628. Again, the shaft 696 is fixed relative to each of the head 692 and the flange 694, but in this case the shaft 696 extends downwardly through the attachment fastener slot 562 (e.g., for engagement with an attachment, such as by first passing through an aperture of any type in the attachment) and then through the attachment fastener slot 562. The free end of the shaft 696 may then be threaded into the nut 698 to clamp a corresponding portion of the attachment between the fastener head 692 and the rail top 560.
Typically one or more attachment fasteners 690 in accordance with the foregoing will be used to secure an attachment to a rail 540, or one or more self-tapping or self-drilling screws may be used to secure an attachment to a rail 540 (e.g., using grooves 566a and/or 566b). However, there may be instances where one or more attachment fasteners 690 in accordance with the foregoing, along with one or more self-tapping or self-drilling screws (e.g., within grooves 566a and/or 566b), may be used to secure an attachment to a rail 540.
One embodiment of a mounting configuration for indirectly securing the rail 540 relative to a building/roofing surface is illustrated in
Additional details regarding the mounting adapter or clip 640 are presented in
The mounting flange 670 is at least generally in the form of a plate and has a first mounting flange surface 672 (e.g., planar or flat) and a second mounting flange surface 674 (e.g., planar or flat) that is spaced from the first mounting flange surface 672 in the vertical dimension 546. The mounting flange 670 may include an elongated mounting slot 678 (e.g., un-threaded) that extends entirely through the mounting flange 670 to facilitate interconnection of the adapter 640 with and underlying building/roofing surface (
The mounting adapter 640 not only may be installed on either the first rail side 600a or the second rail side 600b, but the mounting adapter 640 may be disposed in two different orientations relative to the rail 540 in order to accommodate two different mounting configurations. When the mounting adapter 640 is slidably interconnected with either the first rail channel 604a or the second rail channel 604b in the orientation shown in
It should be appreciated that the rail 540 need not be entirely supported by one or more mounting devices that are interconnected with a given rail 540 by a corresponding mounting adapter 640. At least certain spaced portions of the rail bottom 580 could also be positioned directly on the underlying building/roofing surface (e.g., on upper ends of ribs incorporated by the building/roofing surface). Consider the case where the rail bottom 580 is positioned on a reference plane 548 (e.g., the bottom surface 586a of the first rail bottom portion 582a and the bottom surface 586b of the second rail bottom portion 582b would be contained within this reference plane 548). The second mounting flange surface 674 (which is the portion of the mounting flange 670 that is closest to this reference plane 548 for this mounting configuration) is separated from this reference plane 548 by a distance D1 for the mounting configuration shown in each of
The mounting adapter 640 may also be directly attached to an underlying building/roofing surface. In this case, the mounting adapter 640 would be disposed in the orientation shown in
A seal 720 is disposed between the first mounting flange surface 672 and the underlying building/roofing surface for the illustrated embodiment. The seal 720 could actually be attached to the first mounting flange surface 672 at some point in time prior to installing the rail assembly 530 on a building/roofing surface. In any case, one or more mounting fasteners (e.g., screws) may be directed through the mounting flange 670 (e.g., slot 678, hole 676) and into the underlying building surface. Typically each such screw will extend through a flat upper end of an underlying rib of the building surface, and may terminate within a hollow interior of such a rib.
The mounting flange 670 for the rail assembly 530 is disposed or located between opposing ends 656a, 656b of the outer coupling section 654 in the vertical dimension 546 for the rail 540. Stated another way, the outer coupling section 654 includes a projection 658 that protrudes relative to the first mounting flange surface 672. This projection 658 is disposed adjacent to the first surface 672 of the mounting flange 670, and is located between this first surface 672 and the rail 540 in its lateral dimension 542. The apex of this projection 658 may be disposed within the above-noted reference plane 548, which again contains the bottom surface 586a of the first rail bottom portion 582a and the bottom surface 586b of the second rail bottom portion 582b. In any case, the first mounting flange surface 672 (which is the portion of the mounting flange 670 that is closest to this reference plane 548 for this mounting configuration) is separated from this reference plane 548 by a distance D2 for the mounting configuration shown in each of
A rail 540 may be mounted (indirectly) to a building surface using at least one mounting device, and more typically a plurality of mounting devices, using a corresponding mounting adapter 640, again where each such mounting device is mounted/secured to the building/roofing surface and where a mounting adapter 640 is mounted/secured to a mounting device. A rail may be adapted for direct attachment to a building surface. One such rail is disclosed in
A rail mounting fastener 710 (e.g., a screw, and including a self-tapping or self-drilling screw) may be directed through a mounting rail fastener access 572 on the rail top 560, may be directed through the third rail bottom portion 582c, and may be directed through an underlying portion of a building surface (e.g., a flat upper end of a rib). The rail mounting fastener 710 may include a head 712 and a shaft 714 that is fixed relative to and extends from this head 712. The head 712 could be configured so as to be entirely retained within the lower section 632 of the third pocket 628 for the rail 540 so as to not interfere with an attachment fastener 690 that is used to secure an attachment to the rail 540, although such need not always be the case. A rail seal 730 may be disposed within the rail bottom recess 588 such that the shaft 714 of the rail mounting fastener 710 would also extend through this rail seal 730.
