s claims. (ci. zo-ss) r[his invention relates generally to an `in iprovernent in the means for resiliently holding a panel member,

usually glass or other translucent material, within a supporting frame. My particular adaptationv of my invention constitutes a novel glazing strip employed in the assembly of the translucent panels and supporting frame members forming the sliding vdoors of my Shower Bath Enclosure disclosed in my concurrent application, but it is obvious that the invention may be used for more general purposes.

Heretofore, putty has been generally` used in glazing sash, forming a relatively resilient meanslof `holding the fragile glass in the supporting frame and at the same time sealing the margins against leakage of air, water, etc. Pile fabric has been similarly used.y Putty tends -to harden, crack and disintegrate with age and pile fabric affords poor protection to the `leakage of water` or moisture. These disadvantages become quickly apparent when the sash or panel issubjected both to frequent movement and exposure to water or moisture.

An object of my invention'is to provide a resilient glazing strip, formed by extrusion, of a .plastic material, such as rubber, and constituting an effective seal against water, moisture, air and other elements.

A further object of my invention is' to provide a glazing strip'facilitating the assembly of the. panel being glazed and its supporting frame. l

A further object of my invention is to provide a glazing stnp of such form that its internal stresses hold the margins of said strip in tight contact with adjoining surfaces of the panel and frame members.

A further object of my inventionl is to provide a glazing strip which can be telescoped about theouter margins of the glass or translucent panel `and thereafter inserted into Xed channels in the supporting frame members, effecting insulation therebetween.

Further objects, advantages and novel features of the invention will be particularly mentioned or will become apparent from the further description herein.

In the drawings:

Figure 1 is a partial cross-sectional view of a shower bath enclosure showing my glazing strip disposed in the sliding doors.

Figure 2 is a front view of part of a shower door showing the corner assembly with corresponding crosssectional end views.

Figure 3 is a perspective view of a portion of my glazing strip with the end in cross-section showing the molded design before assembly.

Corresponding numerals of reference refer to like parts throughout the different views.

While I have shown and described herein, for illustrative purposes, a preferred embodiment of my invention, it should be understood that considerable variation in the details of construction may be employed, without departing from its spirit and scope.

Referring to Figure 3, my glazing strip, molded, prefnited States Patent O 2,853,748 Patented Sept. 30, 1958 ICC ` tively. Each of said side walls 11, 11, extends upwardly in spaced apart relationship from the opposite outer margins of the bottom 10, at an angle of inclination less than 90, for a part of its height, then inwardly, on a plane parallel with said bottom plane, forming the shoulders 13, 13, then continues upwardly at an angle of inclination greater than until the inner surfaces thereof contact each other centrally at 14, then ilares off in the outwardly extending lip portion 12, which lip portion lies in a flat plane on its bottom side 15 and slightly curved plane on its upper side 16, reducing in thickness so as to form a relatively sharp edge at its outer margin 17. The conformation of the side walls above described form the inner partial recess 18, 18, for the purpose hereinafter described, and the outer recess 19, 19, which is of a height and depth suflicient to accommodate thev adjoining surfaces of the frame member, as more particularly described hereafter.

The inner width of the bottom 10 should approximate the thickness of the panel of glass or other translucent material so that said strip will tit snugly against its outer margins. The thickness of the bottom and side walls varies with the weight of the panel being supported and should be such as to give sufficient strength to the strip to avoid breaking or tearing. By extending the upper portion of the side walls 11, 11 at an angle greater than normal, when the glazing strip is telescoped on the outer margins of the panel, the outer surfaces of the panel spread the said upper portions of the glazing strip apart from each other, thereby causing the outer edges 17, 17 of the lip portions 12, 12 to be pressed tightly against the adjacent surfaces of the frame members, preventing the entry of moisture 'or other elements.

While my improved glazing strip can be used for varying purposes, I have shown its adaptation to a sliding door in a shower bath enclosure in Figures 1 and 2. While not shown in complete detail, it is to be understood that said enclosure consists of two parallel, slightly overlapping, doors, supported in a surrounding frame upper rim of the bath tub 25', and are supported in position by the guide rails 26 and 27, respectively, on the upper horizontal member 28. The doors 20 and 21 are similar and comprise the panel 29 of glass or other translucent material and the supporting frame, which has the horizontal members 30, 30, and the Vertical side rails 31, 31. Both the horizontal members 30, 39 and the side rails 31, 31 are channeled, as shown, the channel side walls of each terminating in the inturned legs 32, 32.

In assembly, my glazing strip, designated generally as 33, is telescoped upon the outer margins of the panel 29, which enter and ll the channel formed by the bottom 10 and the side walls 11, 11. At the corners, I cut the strip 33 from the bottom to the shoulder 13, so that the corners are turned without bunching or otherwise disturbing the smooth continuity of the lips 12, 12. The horizontal members 30, 30 and vertical rails 31, 31 are then placed in position and fastened together, the inturned legs 32, 32 of the channel side walls engaging and conforming to the recesses 19, 19 of the glazing strip. In the above operation, when the panel 29, with the glazing strip 33 attached, is pushed into the channel formed by the side walls of said horizontal members and side rails, respectively, or vice versa, the recesses 18, 18 permit the compression of the shoulders 13, 13, allowing the inturned legs 32, 32 to pass` over the shoulders and engage the channelsl; 19 ofthe glazing strip 33, after which the shoulders=resume their normal posi-- tion as shown in Figures'Y 1V and 2. When'` so assembled the panel of glass or other material isinsulated and cushioned against the rigid frame members and with the lips-12,. 12 rmly pressing against the adjacent-surfaces of the frame members, an eiective seal against Water or other elements islcreated. l
