Abstract:
A portable public restroom stall door holding device for holding a stall door closed when the lock is broken or inoperative. The device is an elongated C-shaped member which has a pair of gripping edges which may be placed over the top of the stall door and the top or edges of the door post so that the user may temporarily keep the door closed. The device is retained by the user.

Description:
BACKGROUND OF THE INVENTION 
     The field of the invention is door closures and the invention relates more particularly to devices for holding stall doors of restrooms closed when the locking system provided is inoperative. 
     Anyone who has travelled very much realizes that the maintenance of public restrooms is sporadic at best and it is not at all uncommon that the restroom door lock is inoperative. Since the restroom doors tend to have a biasing action which moves them into an open position, the stall becomes essentially unusable when the door will not stay closed. 
     One device is patented relating to this problem and that is shown in U.S. Pat. No. 5,253,908. In this device a pair of disk-like members are held on a nylon line and may be tightened at the intersection of the door and the door jam. This device is somewhat cumbersome to use and is also not particularly compact for storage in a purse or in one&#39;s pocket. 
     BRIEF SUMMARY OF THE INVENTION 
     It is an object of the present invention to provide a device for holding a stall door closed when the latch is inoperative, which device is compact and easy to operate. 
     The present invention is for a portable public restroom stall door holding device. The device is an elongated generally C-shaped member having a first end, a second end, and a body which spans more than about 180° around the C-shaped portion thereof. The C-shaped member terminates in a pair of parallel gripping edges which are slightly flexible and which can be placed over the stall door and the top of the front panel. If the front panel extends above the top of the stall door top, then the device has a pair of outwardly extending gripping edges which permit the device to be placed over the top of the stall door and slid toward the front panel so that the gripping edges surround the front and back of the front panel. The invention is also for the process of using the holding device.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The stall door holding device is shown in perspective view in FIG. 1 and indicated generally by reference character 10. Holder 10 has a body 11 with a first end 12 and a second end 13. Body 11 is an elongated generally C-shaped member oriented so that the open portion of this C is pointed downwardly as shown in FIG. 1. This is done for ease of description and, of course, the device need not be in this position to be operated. 
     Body 11 has a pair of parallel gripping edges 14 and 15 which are preferably rounded. The body is fabricated from stiff but flexible material, preferably a polymer such as polyvinyl chloride. The device need only be about 4&#34; long and 11/4&#34; in diameter and, thus, may be readily stored in a purse or pocket. It can even be used to hold a packet of facial tissues or other objects so that it takes up almost no room at all. 
     Preferably, door holder 10 has a recess 16. Recess 16 extends from about half way up first end 12 to an upper recess end 17 along the top of the body. This recess permits the device to be slid forwardly to surround the surfaces of a front panel in the event the top of the stall door is not at the same level as the top of the front panel. The recess 16 forms a pair of extending arms 18 and 19 which surround a central elongated opening 20. The device is shown in front view in FIG. 2 and can be seen to suspend an arc of approximately 310°. Since the device is made from a stiff but flexible material, this permits the parallel gripping edges 14 and 15 to flex outwardly so that they extend over essentially all public restroom stall doors. A bisecting line 21 passes through the center of the curved inner surface. Preferably, the thickness of the polymer above the bisecting line indicated by reference character 22 is thinner than the thickness of the polymer below that point. This is because it is desired that the device flex over this thin portion 22 and be more rigid below this. In this way the flexure is spread out over approximately 180° distance. Gripping edges 14 and 15 are preferably rounded as shown best in FIG. 2 to facilitate the placement of the device over the top or up onto the bottom of a stall door. 
     The device is shown in side view in FIG. 3 where the shape of the recess can be seen to pass from approximately the mid-point of first end 12 up to recess end 17 which is approximately half way between the first and second ends. 
     A top view of the device is shown in FIG. 4 where the generally parallel gripping edges 14 and 15 may be seen as is the elongated opening 20. 
     Turning now to FIG. 5, the device is shown affixed to the top edge 23 of a public restroom stall door 24. Stall door 24 has an outer edge 25 which when the door is closed is adjacent the door edge 26 of front panel 27. Front panel 27 is shown to have a top edge 28 which is significantly higher than the top edge 23 of door 24. 
     The stall door holder 10 is inserted over the top edge 23 so that its parallel gripping edges 14 and 15 abut the inner and outer surfaces 29 and 30 of door 24. The extending arms 18 and 19 pass over door edge 26 and abut the inner and outer surfaces 31 and 32 of front panel 27. It is to be understood that in the event the top edge 23 is at the same height as top edge 28, stall door holder 10 may be inserted directly downwardly over the intersection of the door and the panel. 
     While it is generally most convenient to use the door holder on the top of the door, it is, however, possible to use it over the bottom edge 33 of door 24 wherein it would be inverted 180° with respect to the position shown in FIG. 5. 
     Preferably, the device is injection molded and formed with a flat face 34 which may be marked with indicia such as the word &#34;occupied.&#34; Preferably, the device is fabricated from a bright plastic so that it is highly visible from outside of the stall. 
     The result is a highly portable, very easy to use device. It is inexpensive to fabricate and intuitive to use. 
     The present embodiments of this invention are thus to be considered in all respects as illustrative and not restrictive; the scope of the invention being indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are intended to be embraced therein.
