Patented Jan. 26, 1954 UNITED STATES PATENT OFFICE FOLDING CLOSURE Solomon M. Collins, Detroit, Mich.
Application February 1, 1952, Serial No. 269,410
11 Claims.
This invention relates to a folding closure, particularly for use in doors of homes and commercial establishments.
It has been known to have folding doors of the wood panel type and also using collapsible plastic folds of the accordion type.
It is an object of the present invention to provide an attractive looking folding door which may be easily installed in a household openin without special built-in hardware and which can be prepared from easily available materials to provide an inexpensive but attractive door closure. Furthermore, the proposed construction provides a hingeless door, one that requires no expensive hand installations of inset hinges.
It is a further object of the invention to provide a particular construction for a folding door closure which lends itself particularly to the type of material being used and also provides a construction which may be adapted to many different types of material in the way of colors, designs and so forth.
The device may be used with fabrics or leather or synthetic plastic sheet materials with any number of combinations of patterns and colors. A simple and effective holding device makes it possible to mount the unit quickly and easily.
Briefly, the invention consists of double sheets of decorative material such as leather, plastic or fabric which are sewed into vertical pockets,
closed at the top, and in which is inserted a stiffening panel of inexpensive material provided with a supporting device which projects through the top of the pockets to co-operate with a slide.
Other details of the invention will be evident in the following description and claims.
Drawings accompany the specification, and the various views thereof may be briefly described as:
Figure 1, an elevation of a completed doorway showing the folding closure in position.
Figure 2, a sectional view on line 2-4 of Figure 1.
Figure 3, an enlarged perspective view Shrine: a joint between two pockets in the material.
Figure 4, a vertical section transversely of th closure member showing the supporting slide and the details of the holding means.
Figure 5, a sectional view on line 5-5 of Fierure 4.
Figure 6, a perspective view of the device showing the relationship of the supporting means to the folding pockets.
In Figure l of the drawings a completed folding door of the type to be described is shown in partially open position. The door frame has two vertical members and 22 and a lintel member 24.
As shown in Figures 2, 3, 4 and 5, the door panel consists of a double sheet of material 26 which is fastened at one edge by snap fasteners 30 to the vertical riser 20 of the door frame. The material 26 is fastened together at 32 to provide a stable hinging panel. At spaced intervals the material 26 is also fastened together to provide hinge areas. In Figure 2 these are shown at 34 and 3B.
A cord, member 38 is locked between seams 39 in the material to provide a neat appearing joint. If the material is a fabric, it may be stitched on either side of the cord member. If it is a plastic material, it may be welded either by the application of heat or the application of a solvent, depending on the nature of the plastic.
The formation of the seams at spaced intervals in the double material provides envelopes or pockets 40 which are closed at the top at 42, as shown best in Figure 6. This construction continues to the edge 44, which is the free edge of the panel.
The construction of the folding panel is completed by inserting within the envelopes 40 stiffener panels formed of thin plates of hard wood, pressed wood, plastic, light metal or similar equivalent material. These plates fill the pockets as shown in sectional drawings and extend substantially the full length of the pockets.
At the top of the plates 50 are inverted channels 52 which are riveted to the top edge of the plates and which have passing through the top wall thereof a supporting rivet 54. This supporting rivet passes through a slide block 56 having side grooves 58 which co-operate with inturned edges 60 of a channel member 62 fastened to the lintel 24 by screws 64, Figure 5.
There is an opening in the top closing edge 42 of the envelope which permits the passage of the slide blocks 56 through the top of the envelope as the plates are inserted. Each panel member, therefore, of the closure unit is supported independently and slidably, the rivets 54 being relatively rotatable so that there is free rotation with the block 56. Thus, the door panel may be opened and closed simply by sliding the blocks 56 and by manipulating them through the suspended panels as they appear in Figure 1.
The assembly of the slide blocks 56 into the track 62 can be accomplished before the entire device is suspended or it can be accomplished through a suitable opening provided at one end of the track.
It will thus be seen that there is disclosed an inexpensive envelope type of folding closure which is readily adaptable to many types of household materials which can be mounted in practically any vertical opening as an attractive and inexpensive closure member.
Iclaim:
1. A folding closure member for vertical openings such as doors which comprises a doubled sheet of flaccid material having a length substantially equal to the height of the opening to be closed and a width substantially equal to the width of said opening, said doubled sheet being joined together in vertical seams spaced along its width to form pockets extending substantially the length of the sheet, and stiffening means comprising panels of relatively rigid material compared to the sheet material slidable into said pockets substantially the full length thereof, fastening means on said panels adjacent the top of said closure member and passing freely through said sheet material, and means slidably associating said fastening means with the top of the opening to be closed to permit said pockets of the closure member to fold together and to extend horizontally.
2. A folding closure member for vertical openings such as doors which comprises a doubled sheet of flaccid material having a length substantially equal to the height of the opening to :e
be closed and a width substantially equal to the width of said opening, said doubled sheet being joined together in vertical seams spaced along its width to form pockets closed at the top except for a small central opening and extending substantially the length of the sheet, and stiffening means comprising panels of relatively rigid material compared to the sheet material slid.-
able into said pockets substantially the full length top of the opening to be closed to permit said L pockets of the closure member to fold together and to extend horizontally.
3.
