1. Field of the Invention
This disclosure relates generally to portal closures and more particularly to a closure for a shower stall.
2. Description of the Related Art
Shower stall closures are generally doors of the conventional kind, that is, having hinges on one side of the door and a latch on the opposing side. The latch is often a magnetic latch, or a spring loaded conventional door latch. The prior art teaches such shower doors in: Lehman U.S. Pat. No. 1,944,440, Backman U.S. Pat. No. 2,627,327, Whitney U.S. Pat. No. 4,598,433, Doan U.S. Pat. No. 244,535, Lax U.S. Pat. No. 3,803,764, Lyons U.S. Pat. No. 5,123,129, Kiefer US2005/0166366, and especially Risk et al U.S. Pat. No. 3,335,784. Such shower doors have certain disadvantages. First of all, shower doors of the conventional type must be made of a structural type of glass that is resistant to being broken and such glass is relatively heavy. Therefore, the framing of a shower stall must be robust in order to support such a heavy door and the framing must be secured to wall panels in an equally robust manner. Such construction is heavy itself, relatively expensive, and generally more time consuming to install. Another disadvantage of such heavy shower doors is that they are difficult to operate, especially by children, older folks and the infirm and senile. An obvious disadvantage of using large glass doors is that they present a significant danger upon being broken.
The presently described invention provides a welcome solution to conventional construction providing light-weight shower door closures that are easy to operate, inexpensive to manufacture and install, durable, and, of course, prevent water from spraying out of the shower room or stall.
In one embodiment, the invention may be a rolling closure type shower door intended to be mounted in a shower stall doorway. The door may comprise multiple (often four or more) pivoted, side-by-side panels. The panels fit underneath a top a structural channel held rigidly in position by a frame with an opening of the channel facing upwardly. The door consists of a plurality of these vertical panels arranged in side-by-side positions, where each of the panels pivotally engaged by a hanger and the hangers engaged with the upper channel, thus holding the panels in an upright attitude. Further, there are a plurality of rods engaged with the hangers and with the panels so that the panels are able to mutually pivot between an open and a closed position. Thus the panels are able to either close-off the shower stall doorway in a closed position, and are alternately able to open the doorway as a pass through in an open position.
Alternatively or additionally, the invention may be a segmented door for a shower stall, built within a fixed structural frame with a horizontal upper and lower channel. The door is constructed using a plurality (often four or more) of vertically disposed, side by side arranged, moveable panels that are hung from the upper channel by a plurality of moveable and pivoting wheeled hangers engaged with this upper channel. These moveable panels are connected to each other by a plurality of pivotally joined horizontal rods, which enables the moveable panels to move as a group. Often one of the moveable panels is joined to the upper and lower channel by clamp-on hinges, so that this panel is only able to move by pivoting. The moveable panels are able to move between an open door configuration and a closed door configuration, and can be designed with slight overlap so as to prevent shower spray from going beyond the panels.
The above described drawing figures illustrate the apparatus and its method of use in at least one of its preferred, best mode embodiments, which is further defined in detail in the following description. It should be understood that what is illustrated is set forth only for the purposes of example and should not be taken as a limitation in the scope of the present device or apparatus and its method of use.
The present invention, a segmented closure for a shower stall entranceway 5, is described now, in detail. As shown in

In summary, then, we see that the first panel 10 (leftmost or rightmost) in this second embodiment, is always hinged to the channels 20, 50 using clamp-on hinges 90 and is hung from channel 20 in the manner described above for panel 10-1 using a hanger 100. Also, we see that the last panel 10 (rightmost or leftmost) is always mounted as described above for panel 10-4 using a short rod 80 and a hanger 100. Finally, we see that each of the remaining intermediate panels 10 that are mounted between the first panel 10 and the last panel 10 are mounted as described above for panels 10-2 and 10-3 using rods 70 and hangers 100. As shown in the figures, the top of each of the panels 10 are sandwiched within channel stock edgings 15. Assuming that the panels 10 are made of glass, as is preferable, such edgings 15 are necessary for pivotally mounting rods 70 and 80 and hangers 100. However, when the panels 10 are made of a material, such as plastic, wood or metal, where such materials are better able to receive pivotal hardware structural engagements, the edgings 15 may not be necessary. In either case, when we refer above to the distal, medial and proximal ends of the “edge 12,” we are referring to either the bare upper or lower edge surfaces of the panel 10 itself, or alternately, to the up-facing (

In some embodiments, in order to create a still firmer seal between adjacent panels when in the shut position, it may be advantageous to cover the vertical edges of the panels (often from top to bottom or at least a substantial amount, i.e. greater than 75%, of the length from top to bottom) with strips of a deformable material such as rubber or plastic (such as polyvinyl). This helps close any remaining openings between the panels, thus reducing the amount of water spray from the shower heads that can penetrate past the shower doorway.
The enablements described in detail above are considered novel over the prior art of record and are considered critical to the operation of at least one aspect of the apparatus and its method of use and to the achievement of the above described uses. The words used in this specification to describe the instant embodiments are to be understood not only in the sense of their commonly defined meanings, but to include by special definition in this specification: structure, material or acts beyond the scope of the commonly defined meanings. Thus if an element can be understood in the context of this specification as including more than one meaning, then its use must be understood as being generic to all possible meanings supported by the specification and by the word or words describing the element.
The definitions of the words or drawing elements described herein are meant to include not only the combination of elements which are literally set forth, but all equivalent structure, material or acts for performing substantially the same function in substantially the same way to obtain substantially the same result. In this sense it is therefore contemplated that an equivalent substitution of two or more elements may be made for anyone of the elements described and its various embodiments or that a single element may be substituted for two or more elements in a claim.
Changes from the described subject matter as viewed by a person with ordinary skill in the art, now known or later devised, are expressly contemplated as being equivalents within the scope intended and its various embodiments. Therefore, obvious substitutions now or later known to one with ordinary skill in the art are defined to be within the scope of the defined elements. This disclosure is thus meant to be understood to include what is specifically illustrated and described above, what is conceptually equivalent, what can be obviously substituted, and also what incorporates the essential ideas.
