The invention relates to roof attachment systems and methods of using same during the installation, maintenance, or repair of a roof on a commercial or residential building structure. The roof attachment systems and methods includes multiple components that function together to provide an anchor point that a person, such as an installer, can couple a safety harness to during the installation, maintenance, or repair of the roof.
Conventional roofs for commercial buildings and residential structures (e.g., single-family homes and multi-family units like condominiums and townhomes) vary in design and composition. Nonetheless, conventional roofs suffer from a number of shortcomings. For example, conventional roofs can be difficult and in some circumstances, dangerous to install, maintain, or repair, especially in inclement weather conditions (e.g., rain, snow, cold, hail, high humidity, high winds or combinations thereof) because by their very nature, roofs are elevated a significant distance above the ground. Thus, conventional roofs can be dangerous to install, maintain, or repair because they present appreciable fall and injury risks to installers and maintenance personnel. Because the fall and injury risks are appreciable, local, state and federal regulatory bodies have enacted stringent codes and regulations to address and minimize these risks. Compliance with these codes and regulations by architects, developers, builders and the installation crew requires careful consideration starting at the planning and design stages of the building structure. Furthermore, compliance with the codes and regulations, including in the field during the construction process, requires of expensive design and installation resources, which are necessary to avoid detrimental actions from the regulatory bodies. Accordingly, there is an unmet need for a roof attachment system that an installer or maintenance worker may use aid in the installation and/or maintenance of the roof.
The description provided in the background section should not be assumed to be prior art merely because it is mentioned in or associated with the background section. The background section may include information that describes one or more aspects of the subject of the technology.
The present disclosure provides a roof attachment system and methods of using same during the installation of a roof on a commercial or residential building. The systems and methods can also be used during maintenance and repair of the roof over its lifetime. The roof attachment system and the related methods of using and implementing the system include an anchor or internal support assembly, and a hook or securement assembly. The roof attachment system enables the installer to utilize at least one internal support assembly during the process of installing the roof. The roof attachment system also enables the installer to utilize at least one internal support assembly and the securement assembly to install the roof, where the securement assembly is useful after the initial installation stages of the roof.
Upon completion of the installation process, the roof includes at least one, and typically multiple, concealed internal support assemblies that provide anchor points arranged a distance apart along the ridgeline of the roof where the anchor points couple with a safety line affixed to the installer. When the roof requires maintenance or repair, the securement assembly can be removably coupled to the internal support assembly to provide another set of anchor points for a safety line affixed to the technician. In this manner, the anchor points facilitate the installation, maintenance or repair by an installer or technician while also helping to reduce the chances that the installer or technician experiences a fall from the roof. Indicia or a marking can be placed on the ridge cap to indicate the location of the internal securement structure, thereby facilitating engagement of the securement assembly to the concealed internal securement structure.
Other features and advantages of the roof attachment system and methods of using same will be apparent from the following disclosure taken in conjunction with the following figures.
The drawing figures depict one or more implementations in accord with the present teachings, by way of example only, not by way of limitation. In the figures, like reference numerals refer to the same or similar elements.
In the following detailed description, numerous specific details are set forth by way of examples in order to provide a thorough understanding of the relevant teachings. However, it should be apparent to those skilled in the art that the present teachings may be practiced without such details. In other instances, well-known methods, procedures, components, and/or circuitry have been described at a relatively high-level, without detail, in order to avoid unnecessarily obscuring aspects of the present disclosure.
While this disclosure includes a number of embodiments in many different forms, particular embodiments will be described in greater detail with the understanding that the present disclosure is to be considered as an exemplification of the principles of the disclosed methods and systems, and is not intended to limit the broad aspects of the disclosed concepts to the embodiments illustrated. As will be realized, the subject technology is capable of other and different configurations, several details are capable of modification in various respects, embodiments may be combine, steps for installation may be omitted or performed in a different order, all without departing from the scope of the subject technology. Accordingly, the drawings and detailed description are to be regarded as illustrative in nature and not as restrictive.
The Figures disclose nine different embodiments of the internal support assembly 200, wherein each embodiment is configured to be used with the securement assembly 600. These and other components of the system 100 function together to provide an anchor point that an installer or a technician can couple his/her safety line 950 to during the installation, maintenance, or repair of the roof 12 and/or the structure 10. This is beneficial for at least the following reasons. First, the internal support assembly 200 is permanently attached to an extent of the building structure 10, namely the roof 12, which enables the installer or service technician to removably couple the securement assembly 600 to the internal support assembly 200 throughout the life of the structure 10. Second, the internal support assembly 200 is concealed underneath an extent of the roof 12, which provides a number of benefits to the roof system 100 in that the internal support assembly 200 does not detract from the aesthetic appearance of the roof 12, it does not require additional openings to be made in the roof 12 which may compromise the structural integrity of the roof 12, and it is not susceptible to premature wear and weathering over the life of the roof 12. Third, the internal support assembly 200 can be coupled to an extent of the roof 12 (e.g., an extent of a truss 20) prior to when that extent of the roof 12 is elevated above the ground and attached to the support frame, such as walls 14, of the structure 10, which: (i) eliminates the need to attach the internal support assembly 200 at a later time and (ii) minimizes the risks that the first person up on the roof 12 is exposed to when installing, maintaining, or working on the roof 12.
Fourth, the roof attachment system 100 meets regulation, requirements, or guidelines set forth by governing or regulating body. For example, the roof attachment system 100 meets Occupational Safety and Health Administration's (“OSHA”) requirements that are identified below and incorporated herein by reference. Fifth, the internal support assembly 200 provides an elevated anchor point for the roof attachment system 100, which: (i) helps ensure that the installer or technician will not make contact with the ground during a fall and (ii) allows the installer or technician to utilize a sufficiently long safety line 950, which reduces the number of times the installer or technician must detach and attach their safety line 950 while on the roof 12, which reduces down-time and increases the working efficiency of the installer/technician. Sixth, the internal support assembly 200 firmly secures the ridge cap 60 to the roof 12, which in turn increases the uplift force that is required to disconnect the ridge cap 60 from the roof 12. The resistance to damaging uplift increases the durability of the roof 12 and helps the roof 12 to better withstand severe weather, such as hurricanes, typhoons and tropical storms. Seventh, the number of different internal support assemblies 200 that a manufacturer must fabricate and a distributor must stock in inventory can be reduced because several of the disclosed embodiments of the internal support assembly 200 are adjustable such that they can be configured to match the pitch of most roofs and thus, the manufacturer does not need to expend unnecessary resources fabricating internal support assemblies 200 for the many various roof pitches. Finally, the roof attachment system 100, the internal support assembly 200, and securement assembly 600 provide other benefits and features over conventional roofs that are obvious to one of ordinary skill in the art.
In general terms, the internal support assembly 200 creates an elevated attachment point 110 that an installer or repair technician can removably couple his/her safety line 950 to during the installation, maintenance, or repair of the roof 12 and/or the structure 10. The elevated attachment point 110 provides two anchor points 112, 114 are available during the first portion or stage of the roof 12 installation by the internal support assembly 200. In particular, the first and second anchor point 112, 114, of the internal support assembly 200 are spaced apart and positioned on either side of the ridgeline, R of the roof 12. Additionally, in most scenarios, multiple support assemblies 200 are installed within the structure 10, which provide multiple elevated attachment points 110 that are spaced longitudinally apart (e.g., typically at least 8 feet and more typically about 16 feet) along the ridgeline, R or length of the roof 12. This configuration of multiple attachment points 110 along the roof 12 help ensure that the installer or repair technician can removably couple his/her safety line 950 for full working coverage of the area of the roof 12 during the installation, maintenance, or repair of the roof 12 and/or the structure 10. In summary, if the structure 10 includes multiple internal support assemblies 200, then the structure 10 will include multiple elevated attachment points 110 that are positioned: (i) on either side of the ridgeline (e.g., first and second anchor points 112, 114 are on opposite sides of the ridgeline) and (ii) along the length of the building 10.
The following embodiments of the internal support assembly 200 are shown in the Figures, wherein: (i)
All of the disclosed versions of the internal support assembly 200-8200 are designed to be used in a similar manor and as such, they have many overlapping components and functional aspects. Accordingly, the following description primarily focuses on the first embodiment of the internal support assembly 200 with the understanding that this disclosure will apply to the other embodiments of the internal support assemblies 1200-8200. As such, similar structures and components amongst these embodiments are identified by similar numbers that are separated by 1,000s. For example, the disclosure in connection with the first receiving structure 324a of the internal support assembly 200 applies to the first receiving structure 1324a of the internal support assembly 1200. Thus, multiple reference numbers for the second through the ninth internal support assemblies 1200-8200 are not included within this specification and instead one shall refer to the disclosure of similar structures for the first embodiment of the internal support assembly 200. This format of the disclosure is done for efficiency and should not be construed to limit the disclosure in any manner. In fact, it should be understood that any structure or feature that is shown within or pertaining to anyone of the disclosed embodiments can be added to, used in connection with, or used instead of a structure or feature of another one of the disclosed embodiments.
The first embodiment 200, third embodiment 2200, fourth embodiment 3200, seventh embodiment 6200 of the internal support assembly 200 can be adjusted to match the pitch of the roof 12, while second embodiment 1200, fifth embodiment 4200, sixth embodiment 5200, eighth embodiment 7200 and ninth embodiment 8200 embodiments of the internal support assembly 200 are fix and are not adjustable. The adjustable internal support assembly 200 provides many resource-related and cost benefits, including that the manufacture does not have to fabricate numerous specific internal support assemblies 200 for each roof pitch and/or installer does not have to stock specific internal support assemblies 200 for each roof pitch (see
All of the disclosed versions of the internal support assembly 200-8200 are designed to be used with the trim system that is described within U.S. Provisional Patent Application Nos. 62/890,005 and 62/916,196, both of which are fully incorporated herein by reference. In particular and as described in greater detail below, the installation order starts with: (i) coupling the internal support assembly 200 to an extent of the structure 10, namely a portion the roof 12, such as an extent of a truss 20 (ii) coupling the installer's safety line 950 to the internal support assembly 200, (iii) installing portions of the roof 12 on the support walls 14, (iv) installing the trim 18 of the roof 12, which includes installing the ridge cap 60 over the internal support assembly 200, (v) disconnecting the installer's safety line 950 from the internal support assembly 200, (vi) coupling the securement assembly 600 within an extent of the ridge cap 60 and the internal support assembly 200, (vii) coupling the installer's safety line 950 to the installed securement assembly 600, and (viii) installing the roofing panels 24 within or over the trim 18, while securing the installer's safety line 950 is connected to the securement assembly 600. This installation order helps ensure that the internal support assembly 200: (i) remains hidden from exterior view, when the roof 12 is installed, and (ii) is directly coupled to an extent of the structure 10 which increases the structural rigidity and durability of the system 100. It should be understood that this installation order is non-limiting and alternative installation orders and configurations (e.g., as described below) are contemplated by this disclosure.
As shown in
The truss attachment assembly 220 is configured to attach to an extent of a truss 20 and can be coupled to the truss 20: (i) prior to the installation of the truss 20 on the walls 14 of the structure 10 or (ii) after installation of the truss 20 on the walls 14 of the structure 10. Coupling the internal support assembly 200 to truss 20 prior to the installation of the truss 20, allows for the installer or builder to couple a safety line 950 to the highest point of the truss 20 before the truss 20 is installed on the structure 10. Once the truss 20 has been properly secured to the walls 14 of the structure 10 and the safety line 950 is coupled to the internal support assembly 200, an elevated attachment point 110 has been created that specifically includes two individual anchor points 112, 114. In particular, this elevated attachment point 110, including the two anchor points 112, 114, is in a raised vertical position relative to: (i) the ground, (ii) foundation of the structure 10, (iii) the upper extent of the walls 14, (iv) the apex 20a of the truss 20 and (v) typically a majority of the roof 12. The combination of the safety line 950 and this elevated attachment point 110 helps reduce the risks that are experienced by the first person up on the roof 12, which includes the risk of falling off the roof 12 and hitting the ground. Additionally, this elevated attachment point 110 is beneficial over an anchor point that is at the height of the upper extent of the wall 14 because this allows the installer to properly use a longer safety line 950. This longer safety line 950: (i) permits the installer to have a wider range of movement to continue installing, repairing, or maintaining the roof 12 and (ii) reduces the number of time the installer must disconnect and reconnect his safety line 950 to new anchor points. Although coupling the internal support assembly 200 to the truss 20 prior to its installation is not required for the use of the internal support assembly's 200, there are significant advantages (e.g., as discussed above) of coupling it prior to the truss' 20 installation.
The truss attachment assembly 220 includes: (i) a first truss attachment segment 224a that forms part of the first internal support structure 202a and (ii) a second truss attachment segment 224b that forms part of the second internal support structure 202b. As such, the first and second truss attachment segments 224a, 224b are in an opposed relationship to one another about the internal support coupling mechanism 204 or the internal support assembly center line, IC. Each truss attachment segment 224a, 224b has a U-shaped configuration that is comprised of an arrangement of three segments 228a, 228b, 230a, 230b, 232a, 232b. In particular, the U-shaped configuration of the truss attachment segment 224a, 224b forms a trust receptacle 226a, 226b that is designed to receive an extent of the trust 20. These three segments 228a, 228b, 230a, 230b, 232a, 232b may have a substantially linear configuration and may be integrally formed with one another. The first segment 228a, 228b is: (i) substantially parallel to the third segment 232a, 232b and (ii) substantially perpendicular to the second segment 230a, 230b. Likewise, the second segment 230a, 230b is substantially perpendicular to both the first and third segments 228a, 228b, 232a, 232b. Finally, the third segment 232a, 232b is: (i) substantially parallel to the first segment 228a, 228b and (ii) substantially perpendicular to the second segment 230a, 230b. This arrangement of segments 228a, 228b, 230a, 230b, 232a, 232b is configured to surround an extent of the truss 20 and preferably on three sides of the truss 20.
Each segment 228a, 228b, 230a, 230b, 232a, 232b has at least one aperture 234 formed through said segments 228a, 228b, 230a, 230b, 232a, 232b, wherein each aperture 234 is designed to receive an extent of an elongated coupler 236 to aid in the coupling of the internal support assembly 200 to the truss 20. The number of apertures 234 that are formed within each of the segments 228a, 228b, 230a, 230b, 232a, 232b may be between 0 and 30, preferably between 0 and 10, more preferably between 1-5, and most preferably 4. There are multiple configurations for the location of these apertures 234, some non-limiting examples are disclosed below. The apertures 234 within the first segment 228a, 228b: (i) may be aligned with one another, and (ii) may not be centered along line Fc of the width of the segment 228a, 228b. Instead, the apertures 234 may be placed further away from the second segment 230a, 230b, which may reduce detachment failures because a larger extent of the truss must fracture before detachment occurs. Additionally, each aperture 234 contained within the first segment 228a, 228b: (i) may not be positioned within a plane that: (a) contains an aperture 234 formed within the second segment 230a, 230b and (b) extends substantially perpendicular to each of the three segments 228a, 228b, 230a, 230b, 232a, 232b, and (ii) may be positioned within a plane that: (a) contains at least one aperture 234 formed within the third segment 232a, 232b and (b) extends substantially perpendicular to each of the three segments 228a, 228b, 230a, 230b, 232a, 232b.
The apertures 234 within the second segment 230a, 230b are preferably aligned with one another and are centered along line SC of the width of the second segment 230a, 230b. The apertures 234 within the third segment 232a, 232b: (i) may be aligned with one another, and (ii) may not be centered along the width of the third segment 232a, 232b. Instead, the apertures 234 may be placed further away from the second segments 230a, 230b, which may reduce detachment failures because a larger extent of the truss must fracture before detachment occurs. Additionally, each aperture 234 contained within the third segment 232a, 232b: (i) may not be positioned within a plane that: (a) contains an aperture 234 formed within the second segment 230a, 230b and (b) extends substantially perpendicular to each of the three segments 228a, 228b, 230a, 230b, 232a, 232b, and (ii) may be positioned within a plane that: (a) contains at least one aperture 234 formed within the first segment 228a, 228b and (b) extends substantially perpendicular to each of the three segments 228a, 228b, 230a, 230b, 232a, 232b.
While the above describes a first possible location of the apertures 234 within the three segments 228a, 228b, 230a, 230b, 232a, 232b, it should be understood that other possible locations for these apertures 234 are possible. In a first embodiment, the apertures 234 that are formed within the first and third segments: (i) could be moved to the center or closer to the second linear segment 230a, 230b or (ii) staggered from one another (e.g., not aligned). In a second embodiment, the apertures 234 formed in the second segment 230a, 230b may be staggered from one another (e.g., not aligned) or may be placed outside of the center of the width of the second segment 230a, 230b. In a third embodiment, none of the apertures 234 contained within the truss attachment assembly 220 may be aligned with one another. Finally, in a fourth embodiment, all of the apertures 234 contained within the truss attachment assembly 220 may be aligned with one another. In alternative embodiments, the combination of the aperture(s) 234 and elongated coupler(s) 236 may be replaced by any type of truss coupling means, which includes welding (e.g., spot or butt welds), projections that extend from the inner surfaces of the segments 228a, 228b, 230a, 230b, 232a, 232b and are received by the truss 20, ball-detent, rivets, or other mechanical or chemical couplers.
In alternative embodiments, the truss attachment assembly 220 may have other configurations without departing from the scope of this invention. For example, the truss attachment assembly 220 could: (i) only include the second segment 230a, 230b and omit the first and third segments 228a, 228b, 232a, 232b, (ii) include the first and second segments 228a, 230a for the first truss attachment segment 224a and include the second and third segments 230b, 232b for the second truss attachment segment 224b, (iii) include a fourth segment that is removably coupled between the first and third segments 228a, 228b, 232a, 232b and opposite of the second segment 230a, 230b, (iv) omit the second segment 230a, 230b, while keeping the first and third segments 228a, 228b, 232a, 232b, (v) include only the first segment 228a for the first the truss attachment segment 224a and include only the third segment 232a for the second truss attachment segment 224b, or (vi) other combination or method of attaching the other components of the internal support assembly 200 to the truss 20.
The purlin support assembly 270 includes: (i) a first purlin support structure 274a that forms part of the first internal support structure 202a and (ii) a second purlin support structure 274b that forms part of the second internal support structure 202b. As such, the first and second purlin support structures 274a, 274b are in an opposed relationship to one another about the internal support coupling mechanism 204 or the internal support assembly center line, IC. Each purlin support structure 274a, 274b has a plate like configuration that provides a mounting surface 272a, 272b that is configured to be directly coupled to an extent of the roof 12 (e.g., purlin 22). In particular, the purlin 22 runs across an extent of the length of the building and links the trusses to one another. The purlin support structure 274a, 274b is coupled to the second segment 230a, 230b of the truss attachment segment 224a, 224b and in some embodiments is integrally formed therewith. The mounting surfaces 272a, 272b of the purlin support structures 274a, 274b are positioned substantially perpendicular to the second segment 230a, 230b of the truss attachment segment 224a, 224b. This configuration positions an extent of the purlin 22 substantially perpendicular to the top surface 20b of the truss 20, when the purlin 22 is coupled to the purlin support structure 274a, 274b.
As best shown in
Each purlin support structure 274a, 274b includes at least one opening 278, and preferably more than a plurality of openings 278, that is designed to receive an elongated coupler 280. The elongated coupler 280 extends from the inner surface 276a, 276b of the purlin support structure 274a, 274b through the opening 278 into the purlin 22. It should be understood that the opening 278 may be omitted and the purlin 22 may be coupled to the purlin support structure 274a, 274b in any manner. For example, the combination of the opening(s) 278 and elongated coupler(s) 280 may be replaced by any type of purlin coupling means, which includes welding (e.g., spot or butt welds), projections that extend from the mounting surface 272a, 272b and are received by the purlin 22, ball-detent, rivets, or other mechanical or chemical couplers.
The receiving assembly 320 includes: (i) a first receiving structure 324a that forms part of the first internal support structure 202a and (ii) a second receiving structure 324b that forms part of the second internal support structure 202b. As such, the first and second receiving structures 324a, 324b are in an opposed relationship to one another about the internal support coupling mechanism 204 or the internal support assembly center line, IC. The first and second receiving structures 324a, 324b are configured to interact with the securement assembly 600 in order to provide the installer with another or third anchor point 116 after the ridge cap 60 has been installed thereover. Each receiving structure 324a, 324b has a J-shaped configuration that is comprised of an arrangement of three portions 328a, 328b, 330a, 330b, 332a, 332b. The three portions 328a, 328b, 330a, 330b, 332a, 332b may have a substantially linear configuration and may be integrally formed with one another. The first portion 328a, 328b has a surface 329a, 329b and is: (i) substantially parallel to the third portion 332a, 332b and (ii) substantially perpendicular to the second portion 330a, 330b. Likewise, the second portion 330a, 330b is substantially perpendicular to both the first and third portions 328a, 328b, 332a, 332b. Finally, the third portion 332a, 332b is: (i) substantially parallel to the first portion 328a, 328b and (ii) substantially perpendicular to the second portion 330a, 330b.
The J-shaped configuration of the receiving structure 324a, 324b forms a securement channel 326a, 326b that is configured to receive: (i) an extent of the ridge cap 60, (ii) an extent of the securement assembly 600, and (iii) an extent of the roof panel 24. Additional details about the securement channel 326a, 326b, ridge cap 60, and securement assembly 600 will be disclosed below. As shown in
The coupling assembly 370 includes: (i) a first coupling member 374a that forms part of the first internal support structure 202a and (ii) a second coupling member 374b that forms part of the second internal support structure 202b. As such, the first and second coupling members 274a, 374b are in an opposed relationship to one another about the internal support coupling mechanism 204 or the internal support assembly center line, IC. The first and second coupling members 374a, 374b are configured to enable an installer to connect their safety line 950 to the internal support assembly 200 without the use of the securement assembly 600. As such, the first and second coupling members 374a, 374b create the first and second anchor points 112, 114, when the internal support assembly 200 is coupled to an installed truss 20.
The first and second coupling members 374a, 374b shown in the Figures are openings 378a, 378b that are formed within third portion 332a, 332b of the first and second receiving structures 324a, 324b. These openings 378a, 378b are designed to receive an extent of the safety line 950; specifically, an extent of the carabiner 952 that is coupled to the safety line 950, as shown in
The adjustment mechanism 420 includes: (i) a first adjustment structure 424a that forms part of the first internal support structure 202a and (ii) a second adjustment structure 424b that forms part of the second internal support structure 202b. As such, the first and second adjustment structures 424a, 424b are in an opposed relationship to one another about the internal support coupling mechanism 204 or the internal support assembly center line, IC. As best shown in
The openings 440a, 440b formed within the first and third extents 428a, 428b, 432a, 432b are configured to receive the internal support coupling mechanism 204, which is shown in the Figures as a pair of elongated fasteners 206a, 206b (e.g., bolt) having couplers 208a, 208b (e.g., nuts) connected thereto. The force exerted by the internal support coupling mechanism 204 on the first and third extents 428a, 428b, 432a, 432b should be sufficient to ensure that the first extents 428a, 428b and third extents 432a, 432b are coupled to one another without a significant amount of play, but is not overly sufficient to the point that the first and third extents 428a, 428b, 432a, 432b cannot be angularly displaced or pivot in relation to one another. This pivotal ability allows for the adjustability of the internal support assembly 200. As shown in
Due to the adjustment mechanism 420, the internal support assembly 200 of
Without this angular displacement capability, the internal angle (alpha) α is fixed and thus cannot me modified to match the angle of the truss 20. This is pivotal capability allows the installer to significantly reduce the number of parts that they must stock, which increases profitability and reduce waste. It should be understood that additional or other structures may be: (i) utilized with this pivotal capability or (ii) utilized instead of the current configuration to provide this pivotal capability. For example, the inner surfaces of the first and third extents 428a, 428b, 432a, 432b may include cooperatively dimensioned jagged projections or “saw teeth” in order to ensure that the internal angle α remains fixed. As described below, the adjustment mechanism 420
While a number of dimensions of the first embodiments have been discussed above, additional dimensions include: (i) width, WTA, of the truss attachment segments 224a, 224b, which may be between 0.5 and 8.5 inches, (ii) length, LTA, of the truss attachment segments 224a, 224b, which may be between 2 and 31 inches, (iii) channel 362a, 362b opening height, CH, which may be between 0.2 and 4.75 inches, (iv) length, LA, of the first extent 428a, 428b of the adjustable structure 424a, 424b, which may between 0.5 and 4.5 inches, and (v) width, WA, of the first extent 428a, 428b of the adjustable structure 424a, 424b, which may between 0.3 and 2.5 inches. Finally, the thickness, MT, of the material that may be used to form the internal support assembly 200 may be between 0.03 and 0.25 inches and preferably 0.13 inches.
At least
The first step in installing the internal support assembly 200 requires the installer to position an extent of the truss 20 within the trust receptacle 226a of the first truss attachment segment 224a. Once the truss 20 is properly seating within the trust receptacle 226a, the installer can secure the first truss attachment segment 224a to an extent of the truss 20 using the apertures 234 and elongated couplers 236. Once all, or at least some, of the apertures 234 have received elongated couplers 235, the installer rotates or pivots the second truss attachment segment 224b such that the truss 20 is properly seated within the trust receptacle 226b of the second truss attachment segment 224b. Once the truss 20 is properly seated within the trust receptacle 226b, the installer secures the second truss attachment segment 224b to the truss 20 using the apertures 234 and elongated couplers 236. Once the internal support assembly 200 is coupled to the truss 20, the truss can be installed on the walls 14 of the structure 10. During this installation process, the installer can secure himself to the internal support assembly 200 prior to when the truss 20 is installed on the structure 10. This configuration helps minimize the risk that is experienced by the installer who is first up on the roof/walls of the structure 10, as shown in
As the installer couples the ridge cap 60 to the roof 12, the installer will need to remove his safety line from the internal support assembly 200 because the internal support assembly 200 is positioned underneath the ridge cap 60 in order to conceal the internal support assembly 200. In other words, when the ridge cap 60 is installed it overlies and conceals the internal support assembly 200. Additionally, when the ridge cap 60 is in the installed position, the wall arrangement of the ridge cap 60 that defines a central cavity that receives an adjustment mechanism 420 of the internal support assembly 200. The installer can then couple his safety line 950 to the next or a second internal support assembly 200 and then disconnect their safety line 950 from the last or first internal support assembly 200. This allows the installer to continue installing the ridge cap 60, while being properly secured to at least one internal support assembly 200. Nevertheless, the installer can switch from being directly connected to the internal support assembly 200 (shown in
As described below and shown in at least
In other words, when the securement assembly 600 is coupled to the structure 10: (i) the receiving block 616a, 616b is positioned within: (a) an extent of the internal support assembly 200 and (b) more specifically within an extent of the receiving structures 324a, 324b, and (b) more specifically within the securement channels 326a, 326b, (ii) an extent of the ridge cap 60 is positioned within: (a) an extent of the securement assembly 600, (b) more specifically within an extent of the mounting member 614a, 614b, and (c) most specifically within the internal support receivers 628a, 628b, (iii) an extent of the internal support structure 200 is positioned within: (a) an extent of the securement assembly 600, (b) more specifically within an extent of the mounting member 614a, 614b, and (c) most specifically within the internal support receivers 628a, 628b, and (iv) an extent of the receiving structures 324a, 324b of the internal support structure 200 is positioned within: (a) an extent of the securement assembly 600, (b) more specifically within an extent of the mounting member 614a, 614b, and (c) most specifically within the internal support receivers 628a, 628b.
The above described positional relationship allows the installer to apply a force, FA (e.g., angular) on the coupling structure 638a, 638b in order to lower the retaining block 634a, 634b into engagement with the top surface 60a of the ridge cap 60. The installer will continue to apply this force on the coupling structure 638a, 638b until the retaining force, FR, that is exerted between the retaining block 634a, 634b and the receiving block 616a, 616b on the ridge cap 60 and third portion 332a, 332b of the receiving structures 324a, 324b is sufficient to keep the receiving block 616a, 616b from easily being dislodged from the securement channel 326a, 326b. In particular, this retaining force, FR, is sufficient if the receiving block 616a, 616b does not become dislodged from the securement channel 326a, 326b upon an accidental fall of an installer, wherein the installer's safety line 950 is nearly parallel with the front edge 617a, 617b of the receiving block 616a, 616b. To insure this retaining force, FR, is sufficient, the installer may tug on the safety line 950 after the mounting member 614a, 614b is coupled to the roof 12 or there may be a force indicator that will indicate when the retaining force, FR, has reached a sufficient level. It should be understood that the retaining force, FR, is not configured to be so great that it can withstand the installer falling in a direction that is: (i) substantially perpendicular to the front edge 617a, 617b and (ii) away from the frontal extent of the mounting member 614a, 614b and towards the rear extent of the mounting member 614a, 614b.
In alternative embodiments, the retaining structure 630a, 630b may be replaced by any known securement means. Such a securement means may be a ratcheting system, wherein the ratcheting system will force the mounting member 614a, 614b towards one another until receiving block 616a, 616b cannot be dislodged from the securement channel 326a, 326b. Alternatively, the ridge cap 60 may have projections that extend between the cap member 64 and the engagement member 62 and are positioned such that the distance between said projections is just larger than the width of the mounting member 614a, 614b. Further, the height HRB of the receiving block 616a, 616b, may be substantially equal to the opening height, CH, such that the installer must apply a force on the mounting member 614a, 614b to position them within the securement channel 326a, 326b. Finally, the retaining structure 630a, 630b may simply be omitted and the installer may attempt to avoid applying a force on the mounting member 614a, 614b that may dislodge it from the securement channel 326a, 326b.
The handle 640a, 640b is designed to receive: (i) a safety line 950 coupler 952 and (ii) a linking member 608. As shown in
The third anchor point 116 is also positioned on the side of the ridge cap 60 that is: (i) opposite of the working side, WS or (ii) on the non-working side, NWS. In other words, there is: (i) a connection side CS of the securement assembly 600 that is: (a) opposite of the working side WS of the roof 12 or (b) on the non-working side, NWS, (ii) a non-connection side CNS of the securement assembly 600 that is: (a) on the working side WS of the roof 12 or (b) opposite of the non-working side, NWS. If the safety line 950 is properly coupled to the connection side CS or opposite of the working side, WS, and the installer accidently falls, the locking 644a, 644b will fail (
While not desirable or ideal, the system 100 has been designed to help prevent the installer from falling, even if the installer happens to couple his safety line 950 to the working side WS or the non-connection side NCS. In particular, this is why the system 100 utilizes two members 614a, 614b that are coupled together by the linking member 608. Referring to the above example, if the installer accidently falls and is coupled to the incorrect members 614a, 614b, the force on the safety line 950 overcomes the retaining force, FR, and pulls the incorrect member 614a, 614b from the securement channel 326a, 326b. The force on the safety line 950 causes the locking means 644a, 644b to fail (
In alternative embodiments, the mooring element 639a, 639b may be replaced by any known mooring means. In particular, such mooring means may include an eyelet, opening, clip, or other mechanical structure that can securely receive an extent of the safety line 950. The members 614a, 614b may have the following dimensions: (i) the width, WRB, of the retaining block 634a, 634b may be between 0.75 and 6.15 inches, (ii) the width, WMM, of the mounting member 614a, 614b may be between 1 and 8 inches, (iii) the width, WH, of the handle 640a, 640b may be between 1.1 and 8.75 inches, (iv) the height, HH, of the handle 640a, 640b may be between 1.75 and 28 inches, (v) the length, LRB, of the retaining block 634a, 634b may be between 0.75 and 6.15 inches, (vi) the length, LMM, of the mounting member 614a, 614b may be between 1.38 and 10.25 inches, (vii) the height, HRB, of the receiving block 616a, 616b may be between 0.15 and 1.25 inches, (viii) the height, HISR, of the internal support receiver 628a, 628b may be between 0.4 and 3.5 inches, and (ix) the height, HSB, of the support block 624a, 624b may be between 0.4 and 3.5 inches. While other dimensions are contemplates, it should be understood that other dimensions are possible.
While the Figures disclose a first embodiment of a securement assembly 600, it should also be understood that other embodiments of the securement assembly 600 are contemplated by this disclosure. For example, the securement assembly 600 could be: (i) the securement assembly 600 that is disclosed within U.S. Provisional Patent No. 62/916,196, (ii) a simply hook or “J” shaped structure that can be received within the securement channel 326a, 326b, (iii) the system 100 may only utilize member 614a, 614b that is positioned on the opposite side of the ridge cap 60 from the working side WS, (iv) a combination of any of these structures.
While the installation procedure is described above in connection with each of the components of the system 100, a summary of such installation is provide here and is shown in

The internal support assembly 200 in connection with the ridge cap 60 increases the amount of force that is required to remove the ridge cap 60 from the roof 12. This is beneficial because it increases the durability of the roof 12 and helps the roof 12 to better withstand severe weather, such as hurricanes, typhoons and tropical storms. To quantify this increase, the test setup 998, including the test fixture 999, that is shown in
