1 Claim. (Cl. 160202) I The present invention relates to, a new and useful im- 'provement in shower stall installations, and more particularly to a sectional telescopic shower door assembly suitable for installation in combination-withatub or in a shower stall.

It is an object of the present inventionto provide a slid- Further objects or the invention and novel features of the; invention=wil-lbe-apparent 'nsm the' following specification and claims and in the accompanying drawings.

in the drawings:

Figure 1 is a view in elevation taken in front of or facing a tub and shower door assembly of the invention.

Figure 2 is a somewhat enlarged vertical transverse cross-sectional view taken along lines 2--2 of Figure 1.

Figure 3 is a somewhat enlarged horizontal cross-sectional view taken along lines 3--3 of Figure 1.

Figure 4 is a horizontal view corresponding to Figure 3 but with the door panels in open position.

Figure 5 is an enlarged vertical transverse cross section taken along lines 2--2 of Figure 1 illustrating the manner in which the panel sections are slidably positioned and the track structure.

Figure 6 is a vertical longitudinal view partly in cross section illustrating the position of one .of the panels of the sectional sliding door member.

Figure 7 is a horizontal view partly in cross section illustrating a modified form of the invention incorporated in a stall shower.

Referring to the drawings in detail wherein like reference characters denote like parts, Figures '1 and 2 show a tub 10 enclosed in a recess defined by side wall portions 11 and 12, rear wall portion 14 and ceiling 13. The tiled portion of wall 14 is shown at 15. Across the top of the recess positioned directly above the outer edge of the tub is positioned a track supporting member 16 in the form of an inverted U-channel. This channel member is fastened to the ceiling between the side walls of the recess by any suitable means, as by screws or the like. Within channel 16 are positioned a plurality of track members which support sliding sectional panels 20, 21, 22 and 23 which panels are slid to open or closed position by means of handle 28. The bottom edges of these panels are guided by guide tracks formed in another U-channel member 17 positioned on the top outer edge portion of the tub below and opposite the upper channel 16. Vertical channel members 18 and 19 are provided at the walls of the recess and serve to receive the outer edges of the outermost panels at each side of the door. These vertical channels extend between members 16 and 17. The panels engage each other through edge members 24, 25 and 26 which are described in greater detail in Figure 3.

United States Patent 0 T Figure 3 illustrates a horizontal cross section in which the relationshipof the vertical channels and the sections is illustrated in closed position. As shown, vertical channels 18 and 19 are positioned at each side of the recess between the upper and lower channels in which'the section panels are guided. Each panel is formed with its vertical edges having outwardly projecting longitudinal flanged portions. These may be in the form of integrally shaped or molded portions, or preferablyin the form of preformed strips as shown at- 24 and 24a on panel 20,25 and 25a on' panel 21, 26 and 26a on panel 22, and 27 and 27a on panel 23. These edge members permit interlocking engagement of the respective panels so that by pulling horizontally on handle 28 and sliding-the first panel in one direction the leading edge in that direction will engage a correspondingedge projection on the adjacentpanel and so on. In closing, .the satne thingwill occur. For example, the edgemember onpanel 20 will engage edge member 25 on panel21, with continuation of the horizontal'sliding movement of panels 20 'and '21 edge member 25 will engage member 26 on panel 22, and

when the door isfully open all of :thepanels will be lined up adjacent and Figure 4. J

In closing, the door handle 28 and panel 20. are slid horizontally to the closed position. In do in g so edge memberf24 engages member 25a" onpanel 21,.member 25 intrirnenga'ges memberv 26a on panel 21; The fully closedposition is illustrated in Figure 3. Another advantage of the arrangement shown in Figure 3 is that the spray head of the shower 29 is positioned so that'the shower spray will flow in a direction away from the junction of the respective edge members to minimize leakage. In opening the door from the inside handle 28a may be utilized. t

The structure of the upper and lower horizontal channel members and the respective track and guiding mem bers is illustrated in Figures 5 and 6. The tracks are formed of depending right angular members 31, 32, 33 and 34 welded or otherwise-fastened to the bottom of channel 16 with the horizontal legs thereby forming tracks. Slidable members 39, 40, 41 and 42 are attached to the respective door panels adjacent the top edges of each.. Preferably, these slidable members are in the form of strips bolted or riveted to the panels, but may be formed integrally therewith. The bottom surfaces of these strips bear against and are in sliding engagement with the upper surfaces of the horizontal tracks, as shown. The door panels 20, 21, Hand 23 are attached to these strips and depend therefrom being thereby slidably supparallel to. end panel 23 as shown in ported by the tracks. The bottom channel member 17, which is attached to the outer top edge of the tub, as

shown in Figure 2, or at the base ofa shower stall if desired, is provided with guiding channels "or grooves within which the bottom edges of thepanels are positioned and guided as shown at the bottom of Figure 5. One preferred manner of providing these channels is by the use of spacers 35, 36, 37 and 38 in the form of elongated right angled members as shown, although any other desirable type of spacing members may be provided. These spacers serve to hold the panels in a vertical linewhile they are being moved horizontally to open and close the door. The vertical channel 19 at one end is also shown in Figure 6, as well as bottom horizontal channel member 17. Since the bottom channel willtend to collect water, openings 43 are provided along its base opening toward the tub to permit drainage.

In Figure 7 is illustrated a modified form of the invention in combination with a stall shower. In this arrangement the walls of the stall are shown at 44, 44a and 44b. The opening to the stall is defined by posts 45 and 46. The panels of the sliding door are 47,48,

Patented Sept. 2, 1958 49 and 50. Handles 51 and 5'2. are provided forsliding the panels in either direction from either side. Edge members 53, 53a, 54, 54a, 55, 55a, 56 and 56a are provided to provide the interlocking arrangement similar to that shown in Figures 3 and 4. Although not shown, the panels slidein tracks supported in a channel, "and are guided by a bottom channehsimilar tothe 'membersil-i lustrated in Figure 5. l i r I Any suitable materials of construction may be utilized for fabricating the products of :nis'invention; 'T he door panels may be of glass, metal or plastic. Preferably, the panels are constructed of translucent plastic material such as polyester resin reinforced with glass fibers. The channel and track members may be of metal or plastic, but are preferably of aluminum Monel metal or stainless or plated steel. The edge engaging members are also preferably of similar metals. The sliding members which engage the tracks andsupport the panels may be of plastic, metal, or other suitable material. In place of the slidable strip, wheels may be used.

This invention is susceptible to various changes in form, proportions or construction, all of which fall within the scope ofthe invention as defined by the appended claim.
