The present disclosure generally relates to a fenestration unit and, more particularly, relates to a weatherstrip carrier that removably attaches to a fenestration unit.
Fenestration units, such as sliding doors and windows, may include features for managing rainwater, snow runoff, sleet, water from nearby sprinkler systems, and/or other water. These features may help divert water and/or channel water away from the interior of the structure.
However, several challenges remain in this regard. For example, some of these features may fail when subjected to extreme conditions and allow for undesirable water intrusion. Also, for fenestration units with an active or movable panel (e.g., a sliding door or window), these water diversion features may disadvantageously increase the operating force that is necessary for moving the panel. Furthermore, these features may present manufacturing difficulties, for example, by increasing part count, by increasing assembly time, by decreasing manufacturability, etc.
Thus, it is desirable to provide improved water management features for a fenestration unit, including features that provide more robust water diversion and other weather resistance. It is also desirable to incorporate such features without significantly increasing necessary operating forces for moving panels of the fenestration unit. Furthermore, it is desirable to provide weather management features that provide increased manufacturing efficiencies. Other desirable features and characteristics of the present disclosure will become apparent from the subsequent detailed description and the appended claims, taken in conjunction with the accompanying drawings and this background discussion.
In one embodiment, a weatherstrip carrier for a fenestration unit is disclosed. The weatherstrip carrier includes a weatherstrip support configured to hold a weatherstrip. The weatherstrip carrier also includes a coupling member that is attached to the weatherstrip support. The coupling member is configured to removably attach to the fenestration unit. The coupling member includes a spine, a first projection, and a second projection. The first and second projections project from the spine in a common direction. The coupling member is resiliently flexible for movement between a neutral position and a flexed position. The first and second projections are biased toward each other when the weatherstrip carrier is in the flexed position. The second projection is configured to be removably received within the fenestration unit, with the weatherstrip carrier in the flexed position, and with the first and second projections cooperatively compressing against the fenestration unit to retain the weatherstrip carrier thereon.
In another embodiment, a method of manufacturing a weatherstrip carrier for a fenestration unit is disclosed. The method includes forming a weatherstrip support of the weatherstrip carrier. The weatherstrip support is configured to hold a weatherstrip. Moreover, the method includes forming a coupling member that is attached to the weatherstrip support. The coupling member is configured to removably attach to the fenestration unit. Forming the coupling member includes forming the coupling member to include a spine, a first projection, and a second projection. The first and second projections project from the spine in a common direction. The coupling member is resiliently flexible for movement between a neutral position and a flexed position. The first and second projections are biased toward each other when the weatherstrip carrier is in the flexed position. The second projection is configured to be removably received within the fenestration unit, with the weatherstrip carrier in the flexed position, and with the first and second projections cooperatively compressing against the fenestration unit to retain the weatherstrip carrier thereon.
In an additional embodiment, a fenestration unit is disclosed. The fenestration unit includes a frame and a panel that is supported by the frame. The fenestration unit also includes a weatherstrip system that is removably attached to the frame. The weatherstrip system includes a weatherstrip carrier and a weatherstrip. The weatherstrip carrier is configured to retain the weatherstrip against the panel. The weatherstrip carrier includes a spine, a first projection, and a second projection. The first and second projections project from the spine in a common direction. The weatherstrip carrier is resiliently flexible for movement between a neutral position and a flexed position. The first and second projections are biased toward each other when the weatherstrip carrier is in the flexed position. Also, the second projection is removably received within the frame, with the weatherstrip carrier in the flexed position, and with the first and second projections cooperatively compressing against the frame to retain the weatherstrip carrier thereon.
The present disclosure will hereinafter be described in conjunction with the following drawing figures, wherein like numerals denote like elements, and wherein:
The following detailed description is merely exemplary in nature and is not intended to limit the present disclosure or the application and uses of the present disclosure. Furthermore, there is no intention to be bound by any theory presented in the preceding background or the following detailed description.
Broadly, example embodiments disclosed herein include a weatherstrip carrier of a weatherstrip system for a fenestration unit, such as a window, door, sliding door, etc. The weatherstrip carrier may support, hold, and retain a weatherstrip against a passive or active panel of a sliding door or horizontally-sliding window in some embodiments. The weatherstrip carrier may also removably attach to the frame of the fenestration unit with an attached weatherstrip substantially sealed against the panel to thereby divert water away therefrom. The weatherstrip may be removably attached to the carrier in some embodiments so as to be replaceable. In some embodiments, the weatherstrip carrier may removably clip, clamp, or otherwise compress against a frame of the fenestration unit. The weatherstrip carrier may resiliently and elastically deform from a neutral position to a flexed position. First and second members of the weatherstrip carrier may be resiliently biased toward each other to cooperatively compress against the frame, thereby retaining the carrier on the frame with the weatherstrip substantially sealed against the panel of the fenestration unit.
Furthermore, the weatherstrip carrier may include a first compression member and a second compression member (i.e., a first jaw-like projection and a second jaw-like projection) that are attached by a spine of the weatherstrip carrier. The second compression member may be received in an aperture of the fenestration unit frame, the spine may overlap and cover an exterior surface of the frame, and the second compression member may cooperate with the first compression member to grip onto and clip to the frame. The weatherstrip carrier may be resiliently flexed when removably attached to the frame such that the compression members are biased together and such that the compression members cooperatively clip to the frame of the fenestration unit. In this position, the weatherstrip may be supported on and sealed against the panel of the fenestration unit and angled away therefrom to divert water.
The weatherstrip carrier may include these and/or other features that provide highly robust weather resistance. These features may be incorporated without significantly increasing necessary operating forces for moving the panels of the fenestration unit. Furthermore, one or more features of the present disclosure may provide manufacturing benefits, such as lower part count, increased manufacturing efficiency, and/or other advantages.
Referring initially to
In some embodiments, the fenestration unit 104 may be a sliding door, and the majority of the discussion will refer to the fenestration unit 104 as such as an example. However, it will be appreciated that the weatherstrip carrier 102 may be configured for a horizontally-sliding window, a swinging door or window, or another type of fenestration unit 104 without departing from the scope of the present disclosure.
As shown in
The sill 114 may be elongate and may extend in a longitudinal direction along a longitudinal axis 126. The cross-sectional profile of the side 114 may remain substantially constant along the axis 126. The rail 124 may support sliding movement of the panel 112 of the fenestration unit 104. More specifically, in embodiments in which the panel 112 is an active panel of a sliding door fenestration unit 104, the rail 124 may support sliding movement of the panel 112 along the axis 126 (e.g., using one or more roller elements, roller element bearings, etc.).
As shown in
The weatherstrip carrier 102 may generally include a spine 140 as shown in
The weatherstrip carrier 102 may further include a first projection 141. The first projection 141 may be wedge-shaped in cross section (
The leading end 154 may include an aperture, such as an elongate groove 155, a depth-direction of the groove 155 being directed laterally into the first projection 141. The groove 155 may receive the weatherstrip 106 in some embodiments, for example, for removably receiving the weatherstrip 106. Accordingly, the leading end 154 of the first projection 141 and the groove 155 therein may define the weatherstrip support 127 of the weatherstrip carrier 102.
The weatherstrip carrier 102 may additionally include a second projection 142. The second projection 142 may be a barbed or finned strip that projects laterally from the spine 140. The second projection 142 may project from the spine 140 from an area that is spaced away from the second edge 146 of the spine 140 so as to define a flange 180 between the second edge 146 and the second projection 142.
In some embodiments, the second projection 142 may include a base strip 160 that projects from the spine 140 laterally in the same direction as the first projection 141. The base strip 160 may include an upper surface 170 that faces toward the lower inner surface 152 of the first projection 141, and a lower surface 172 that faces in the opposite direction. The second projection 142 may also include a plurality (e.g., four) barbs 162. The barbs 162 may be elongate and relatively flat, planar strips that project from the base strip 160 at an angle (e.g., at an approximately forty-five-degree (45°) angle) relative to the lateral direction. At least one of the barbs 162 may be angled away from the upper surface 170 and back toward the spine 140, and at least one of the bars 162 may be angled away from the lower surface 172 and back toward the spine 140. The barbs 162 may be resiliently flexible for flexure relative to the base strip 160.
In some embodiments, the spine 140, the first projection 141, and the base strip 160 of the second projection 142 may be made of a first material, such as a first polymeric material, whereas the barbs 162 may be made of a second material, such as a second polymeric material. In some embodiments, the spine 140, the first projection 141, and the base strip 160 may be constructed from chlorinated polyvinyl chloride (CPVC) material, whereas the barbs 162 may me be constructed from a thermoplastic elastomer material of a higher flexibility. Thus, the material of the barbs 162 may have higher flexibility than the other portion of the carrier 102. These different portions constructed from different materials may be integrally connected, for example, via a co-extrusion process such that the weatherstrip carrier 102 may be unitary and monolithic.
The carrier 102 may exhibit a degree of flexibility so as to move from a neutral position (shown in
As shown in
Moreover, as shown in
With the weatherstrip 106 attached to the carrier 102, the coupling member 128 of the carrier 102 may be removably mounted on the frame 110 of the fenestration unit 104. More specifically, the second projection 142 may be inserted and received within an aperture 119 of the upstand 118 of the frame 110. The aperture 119 may be an elongate kerf that extends laterally into the upstand 118 and that extend longitudinally along the axis 126. The second projection 142 may be inserted manually, the barbs 162 may resiliently bend during insertion, and the barbs 162 may thereafter bias against the internal surface of the aperture 119 to remain frictionally engaged to the frame 110.
Furthermore, as the carrier 102 is advanced onto the frame 110 in the lateral direction, the surface 152 of the first projection 141 may slide over a horizontal upper lip surface 131 of the upstand 118. This may resiliently deflect the carrier 102 and slightly pivot the first projection 141 away from the second projection 142 to change the angle 153 and seat the first projection 141 onto the upper lip surface 131. The carrier 102 may continue to advance onto the frame 110 until the strip 130 abuts and resiliently flexes against the panel 112. The strip 130 is shown in solid lines in
When attached to the upstand 118 in the position shown in
The carrier 102 also retains the weatherstrip 106 for effectively diverting water runoff, etc. from the panel 112 and away from the gap 122 within the frame 110. Also, the sloped upper exterior surface 150 may be sloped away from the panel 112 and sloped relative to the direction of gravity to further divert water runoff, etc. away from the panel 112 and the gap 122 within the frame 110.
Referring now to
The coupling member 1128 of the carrier 1102 may include the spine 1140, the first projection 1141, and the second projection 1142. The coupling member 1128 may be configured to resiliently bias for compressing against a fenestration frame, similar to the embodiment of
Like the embodiments of
Moreover, the weatherstrip systems of
In additional embodiments of the present disclosure, the second projection 142, 1142 may vary from the illustrated embodiment. Instead of being integrally attached to the spine 140, 1140, the second projection 142, 1142 may be removably attached to the spine 140, 1140. For example, the second projection 142, 1142 may be a screw or other fastener that extends through the spine 140, 1140 to fasten to the panel 112. In addition, the first projection 141, 1141 may flex resiliently to compress against the panel 112, similar to the embodiments discussed above. Furthermore, it will be appreciated that the spine 140, 1140 or other portions may be adhesively attached (e.g., via double-sided tape), or otherwise attached to the panel 112 without departing from the scope of the present disclosure.
