DETAILED DESCRIPTION
Before turning to the figures, which illustrate the exemplary embodiments in detail, it should be understood that the present disclosure is not limited to the details or methodology set forth in the description or illustrated in the figures. It should also be understood that the terminology is for the purpose of description only and should not be regarded as limiting. An effort has been made to use the same or like reference numbers throughout the drawings to refer to the same or like parts.
Referring to FIG. 6, in an embodiment illustrating one example of a conventional wall jamb 200, the wall jamb 200 is a rigid extrusion, asymmetrical about a centerline CL. A leg 210 of the wall jamb 200 located towards an outside of the showering enclosure is longer than a leg 211 located towards an inside of the showering enclosure. The leg 211 may not be part of the rigid extrusion, but a resilient material applied separately, as needed. A bumper 220 may be placed locally at a wall connection where the wall jamb 200 is anchored to a wall (not illustrated), or at other points along the wall jamb's length, to prevent shower door panels 230 from contacting the wall jamb 200 in order to prevent damage to the shower door panels 230. Water is contained within the showering enclosure by an overlap of the wall jamb legs 210 and 211 and the shower door panels 230. In such a configuration, shower door panels 230 that are disposed closer together, disposed closer to the wall jamb 200, and are more overlapped by the legs 210 and 211 of the wall jamb 200 provide better water containment.
Referring to FIG. 7, in another embodiment illustrating one example of a conventional wall jamb 300, the wall jamb 300 is a rigid extrusion, symmetrical about a centerline CL. A bumper 320 may be placed locally at a wall connection where the wall jamb 300 is anchored to the wall (not illustrated), or at other points along the wall jamb's length, to prevent the shower door panels 330 from contacting the wall jamb 300 in order to prevent damage to the shower door panels 330. Water is contained within the showering enclosure by an overlap of wall jamb legs 310 and the shower door panels 330. To help with water management, a detail with a sharp bend 340 may be present on outermost edges of the wall jamb 300, or protruding geometry may be present on the innermost edges of the wall jamb 300. The sharp bend 340 or protruding geometry prevents water from “wrapping” around the wall jamb 300 and exiting the showering enclosure. In such a configuration, shower door panels 330 that are disposed closer together, disposed closer to the wall jamb 300, and are more overlapped by the legs 310 of the wall jamb 300 provide better water containment. Other variations of the wall jamb 300 may include having a “bridge” of the H-shape wall jamb 300 be asymmetrical.
Referring generally to FIGS. 1-5, an exemplary embodiment relates to an improved resilient wall jamb seal for a shower door that provides a water barrier between the connection of the shower door and the wall and may also maintain the closed position of the shower door and decelerate it upon closing. The resilient wall jamb seal, described in further detail below, replaces a typically rigid wall jamb (see FIGS. 6 and 7) with a resilient wall jamb. The wall jamb resists the shower door from rolling open under the weight of the shower door. In addition, the configuration of the wall jamb reduces the size of the wall jamb required to provide a water barrier and may eliminate the need for installing a bumper to cushion the closing of the door at a location of the wall jamb.
Moreover, the installation method for the wall jamb described in further detail below eliminates the need for drilling holes and installing mechanical fasteners to walls of a showering enclosure. The installation method changes the order in which the shower door and the wall jamb are installed and reduces the installation time.
Referring to the figures more particularly, as illustrated in FIG. 1, an exemplary embodiment of a wall jamb 100 includes legs 110, a base 111 connecting the legs 110, and an adhesive 140 (e.g., a pressure sensitive adhesive) disposed at an exterior surface of the base 111. Optionally, a plurality of fins 112 that protrude from the base 111 may be included. In one embodiment, the legs 110, the base 111 and the fins 112 are preferably integrally formed. The legs 110 and the base 111 form a generally U-shaped wall jamb 100 having a bowed-in profile. In an exemplary embodiment, the wall jamb 100 is symmetrical about a center line drawn along a direction in which the shower door panel 130 is inserted, but may also be asymmetrical about its center line.
One of ordinary skill in the art will appreciate that FIGS. 1-5 are top end views and the wall jamb 100 (i.e., the legs 110, the base 11, the fins 112 and the adhesive 140) is elongated and extends along a majority of the entire height up to the entire height of the shower door panel 130 (i.e., a majority of the entire height up to the entire length of a side of the shower door panel 130 that abuts a wall 150 of the showering enclosure).
The wall jamb 100 is configured to receive the shower door panel 130 (see FIGS. 2-5) between the legs 110 when the shower door panel 130 is being closed or in a closed position such that the wall jamb 100 forms a wall jamb seal. The wall jamb 100 is made of a resilient material such as a rubber or other flexible and resilient material that allows for the shower door panel 130 to expand an opening 113 of the wall jamb 100. In an exemplary embodiment, the wall jamb 100 may further include a rigid material 114 such as a metal or a plastic, configured to help the wall jamb 100 maintain its shape. The rigid material 114 may be generally U-shaped and disposed in the base 111 and/or in at least a bottom portion of the legs 110.
When the shower door panel 130 is received in the wall jamb 100, an interference fit between the rigid shower door panel 130 and the legs 110 of the wall jamb 100 forces the opening 113 of the wall jamb 100 to widen, via a deformation of the legs 110 (see FIG. 3). As illustrated in FIG. 1, in an original state, a middle portion of the opening 113, defined by the bowed-in legs 110, is narrower than other portions (i.e., a front portion and a rear portion) of the opening 113. Thus, when the shower door 130 is received in the wall jamb 100, the bowed-in portion of the plurality of legs 110 (i.e., the portion disposed at the middle portion of the opening 113) is capable of, but not limited to, obtaining a clamp-like hold on the shower door panel 130, or a close fit. The clamp-like hold allows the wall jamb 100 to achieve better water containment and to maintain the closed position of the shower door panel 130 in the event that the shower door panel 130 is unevenly hung and prone to opening on its own. The bowed-in profile of the wall jamb 100 allows the shower door panel 130 to self-align with the wall jamb 100 as the shower door panel 130 is closed. The geometry of the wall jamb 100 also decelerates the shower door panel 130 in the event the shower door panel 130 is slammed shut. In other words, the wall jamb 100 provides a bumper-like cushion to the shower door panel 130.
The resilient material of the wall jamb 100 allows the opening 113 of the wall jamb 100 to return or recoil into its original configuration (see FIGS. 1 and 4) when the shower door panel 130 is opened (i.e., when the shower door panel 130 is not received between the legs 110 of the wall jamb 100). The geometry of the wall jamb 100 allows for a low input force required to open a shower door panel 130 (see FIGS. 2-5) and remove the shower door panel 130 from the wall jamb 100.
The pressure sensitive adhesive 140 is pre-applied to the exterior of the base 111 of the wall jamb 100. The pressure sensitive adhesive 140 is configured to withstand moisture and variations in temperature without losing adhesion strength. The pressure sensitive adhesive 140 may be, for example, double-sided tape.
Rather than installing the shower door panel 130 after installing the wall jamb 100, the wall jamb 100 is instead installed using the shower door panel 130 as a locating guide after the shower door panel 130 is installed in position. To install the wall jamb 100, the wall jamb 100 is placed onto the shower door panel 130, such that the shower door panel 130 is received between the legs 110 of the wall jamb 100. An adhesive backing material of the pressure sensitive adhesive 140 may then be incrementally or completely removed. For example, when the adhesive backing material of the pressure sensitive adhesive material is incrementally removed, a portion of the adhesive backing material is removed, and the shower door panel is pushed toward a wall 150 of the showering enclosure (i.e., the shower door panel 130 is closed) such that the portion of the wall jamb 100 from which the adhesive backing material was removed adheres to the wall 150. Then, an additional portion of the adhesive backing material can be removed such that an additional portion of the wall jamb 100 from which the additional portion of the adhesive backing material was removed may be adhered to the wall 150 of the showering enclosure. The process is repeated until the adhesive backing material is completely removed and the entire wall jamb 100 is adhered to the wall 150. Incremental removal of the adhesive backing provides control over the placement of the wall jamb 100 on the wall 150 in the event that the shower door panel 130 is not completely straight or plumb. Alternatively, the entire adhesive backing material may be removed in a single step such that the entire wall jamb 100 adheres to the wall 150 when the shower door panel 130 is closed.
When the wall jamb 100 is installed, the fins 112 of the wall jamb 100 spread out and the exposed pressure sensitive adhesive 140 adheres to the wall 150. The fins 112 are thin and flexible, allowing the fins 112 to conform to a surface of the wall 150. When the shower door panel 130 is opened, the wall jamb 100 will remain adhered to the wall 150 (see FIG. 4). However, if desired, the installer may manually push the wall jamb 100 onto the wall 150, firmly along a length of the wall jamb 100, to ensure the pressure sensitive adhesive 140 is fully engaged with the wall 150. As a result, the wall jamb 100 is positively located, in-line with the shower door panel 130 on the wall 150.
The method of installing the wall jamb 100 described above eliminates the need for drilling holes or installing mechanical fasteners in the wall 150, as required in the methods for installing conventional wall jambs. In addition, by changing the order in which the shower door components are installed, the overall installation time can be reduced.
In an exemplary embodiment, installation may include an additional step of filling any voids between the wall 150 and the wall jamb 100 with a silicone sealant 160 (see FIG. 5). Specifically, the silicone sealant 160 may be used in any location where the fins 112 do not fully cover and seal the voids. One of ordinary skill in the art will appreciate that the addition of the silicone sealant 160 is optional and not required for water containment.
Although only one shower door panel 130 is illustrated in FIGS. 2-5, one of ordinary skill in the art will appreciate that a shower door typically comprises two shower door panels (i.e., double doors), as illustrated in FIGS. 6 and 7. When both shower door panels are in the closed position, a first shower door panel (e.g., an inside shower door panel) abuts a wall nearest to or upon which a shower head is mounted, and a second shower door panel (e.g., an outside shower door panel), abuts a wall opposite to the wall that the first shower door panel abuts. Thus, in one embodiment, the wall jamb 100 allows for a smaller wall jamb to be used, as compared to the wall jambs 200 and 300 of FIGS. 6 and 7, in that a single wall jamb 100 can be used to seal one side of each shower door panel. In other words, a first wall jamb 100 can be provided for the first shower door panel at the wall nearest to or upon which the shower head is mounted, while a second wall jamb 100 can be provided for the second door at the opposite wall. In contrast, the wall jambs 200 and 300 of FIGS. 6 and 7 receive both shower door panels 230, 330 within a single wall jamb 200, 300. In this embodiment, only one side of each shower door panel is received in the wall jamb 100 (i.e. a total of two wall jambs 100 are provided). Because one self-aligning wall jamb 100 is provided for each of the shower door panels, the wall jambs 100 may still be easily installed without cumbersome measurement or alignment steps, even if the shower door panels are not disposed perfectly parallel to each other.
In other embodiments, a wall jamb 100 may be provided on both sides of each shower door panel, such that the shower door panel is received in a wall jamb 100 when it is in a closed position (described above) and when it is in a full open position (i.e., when the first shower door panel abuts the opposite wall and the second shower door panel abuts the wall nearest to or upon which the shower head is mounted). In this embodiment, a total of four wall jambs 100 are provided.
The wall jamb 100 may be used with any shower door panel 130. As described above, the wall jamb 100 provides a bumper-like cushion to the shower door panel 130, eliminating the need to install a separate bumper. However, in other embodiments, the wall jamb 100 may be used with a shower door panel 130 having a bumper 120 integrally formed or separately formed and connected to the shower door panel 130. The bumper 120 is disposed between the shower door panel 130 and the wall jamb 100.
According to the embodiments described above, an aesthetically pleasing wall jamb for a shower door is provided. The wall jamb serves as a water barrier between the connection of the shower door and the wall and maintains the closed position of the shower door.
