Description of the Prior Art While T-shaped locker handles have been widely used in lockers installed in gymnasiums and military installations, present handles include several significant disadvantages. One of the main disadvantages is that such handles have never been successfully used with a three-point latch system; that is, a system which latches a locker door at the top, bottom and mid-portions of the door and is operated by simple movement of the T- handle itself. In the past, most T-handle lockers have only had one point latching systems, and thus, lockers subject to heavy abuses such as those used in gymnasiums, have often been damaged or broken into because of the lack of effective latching at the top and bottom.
Another disadvantage of prior T-type handles is that, because of their construction, it had been virtually impossible or at least extremely difficult to gain access to the back of the locking means to open it or to obtain information from it in case an emergency requires access to the locker by authorized personnel. Any upward pivoting movement of the locking means was always obstructed by handles thereby preventing access to the back.
Finally, while prior T-type handles and latching mechanisms are relatively complex and therefore, expensive to manufacture, they have not proven to be rigid enough in either construction or mounting to withstand the abuse to which the lockers on which they are placed are constantly subjected.
SUMMARY OF THE INVENTION The present invention provides a novel T-shaped locker handle assembly which is securely mounted to a locker door or frame and operates a three-point latching system while being formed so as to offer easy access to the back of a locking means in locked condition. This T-type locker handle overcomes the disadvantages of the prior art and satisfactorily meets military requirements by a handle means which is disposed for rotation relative to a locker door in a hollow handle bearing means mounted on the door. The handle means includes an integrally formed gripping portion corresponding to the top of a T which is disposed generally transversely to a cylindrical stern portion corresponding to the stem of a T. The stem portion has an opening formed therein to receive the shackle of a locking means. The gripping portion is offset from the central axis of the stem portion so that when the stem portion is inserted into the handle bearing means and the handle is in operating condition, the locking means received through corresponding openings in the stem portion and handle bearing means may be pivoted upwardly to a horizontal position allowing easy access to information or secondary access locking means found at the back of the locking means.
The handle means has mounted for rotation with it, at the inward end of the stern portion, a key-shaped latching cam. This latching cam may be pivoted with the handle means to either enter cooperative openings formed in the door and the frame adjacent to it or be positioned on the opposite side of the frame flange from the door, to latch the door at its mid-point. The latching cam also has, pivotally mounted on it, opposite upper and lower connecting rods having latch means at outer ends movable into and out of cooperatively aligned openings in the door and the frame to engage or disengage the frame and prevent opening of the door. The door may thereby be latched at three points along its height to hold it securely in closed position and prevent damage due to bending of the door at the top or bottom.
The stem portion of the handle means is formed with an opening therethrough which may be cooperatively aligned with an opening formed in the handle bearing means mounted on the door so that when the gripping portion of the handle means is in generally horizontal position and the door is latched, a shackle of a locking means may be inserted through these openings to prevent rotation of the handle means and unlatching of the door. However, since the gripping portion of the handle means is offset with respect to the central axis of rotation of the stem portion, the entire locking means, though in locked condition, may be rotated forwardly and upwardly to allow access to its back. This permits authorized personnel to obtain information from the back of the lock or to open the lock by a secondary access locking means at its back thereby, in emergency situations, to gain access to the interior of the locker.
severe abuse.
It is another object of this invention to provide a locker handle assembly which is so formed to allow a locking means, in locked condition, to prevent movement of the handle, while being movable itself to a position permitting access to the back of the locking means.
It is a further object of this invention to provide a locker handle assembly including a latching means which is operable and effective to provide three-point or one-point latching of the locker door with respect to the locker frame.
It is still a further object of this invention to provide a locker handle assembly including a handle means mounted within and rotatable with respect to a handle bearing means, which is connected to a latching means designed to provide three-point latching of the locker door with respect to the locker frame.
These and other objects of this invention will become evident from the following description of the drawings illustrating a preferred embodiment wherein:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings and in particular, to FIG. 1, the locker handle assembly of this invention is shown generally at 10. This locker handle assembly 10 is shown mounted on a locker door 12 which is hingedly mounted over an opening on a locker frame 14 to form a closure member for a locker assembly. While it is recognized that the locker handle assembly 10 of this invention could also be mounted on a double door type locker assembly wherein the numeral 14 would refer to the opposite door, the latching means operated by the locker handle will remain of the same construction and this invention will function in the same manner with the same result as in a single door assembly. It is also clear that'locker handle assembly 10 could be mounted on the frame 14 of the locker assembly by minor modifications of the embodiment shown. Again, however, the locker handle assembly 10 would function in the same manner to achieve the same result.
The locker handle assembly 10 is shown in FIG. 1 having a locking means or padlock 16 in locked condition with the shackle 17 of the padlock in cooperative engagement with the locker handle assembly 10 to prevent movement of the locker handle assembly 10 and subsequent opening of the door. The padlock 16 has a rear face 18, as shown in FIG. 3, which normally contains information such as a serial or master code number which must be obtained to open the lock. It may contain a secondary access lock of a key type to allow a master key to be used directly to open the locking means 16.
The locker handle assembly 10, as shown in FIGS. l-3, 5 and 8, includes a handle bearing means 20 having a generally flat plate portion 19 having upper and lower extensions through which fastening means 21 may be inserted through corresponding openings formed in the door 12 to maintain the entire locker handle assembly 10 is a secure and rigid position on the locker door 12. Fastening means 21 may consist of an unslotted screw threaded at its one end to engage a hexagonal nut with a lock washer interposed between the opposite side of the door 12, as shown in FIG. 2. The handle bearing means has, at its center, a sleeve portion 23 having a generally cylindrical exterior and hollow interior bore tapered very slightly toward its rear. This sleeve portion 23 extends from either side of plate 19 with the rearward portion extending through a corresponding opening 25 on door 12.
The sleeve portion 23 of the handle bearing means 20 has disposed within it, for rotation relative to it, a handle means shown generally at 22. Handle means 22 is generally shaped in the form of a T, thus giving rise to the name T-Type Handle." Handle means 22 includes a gripping or bar portion 26 which is integrally formed with a stem portion 24 disposed generally normally to it. Stem portion 24 has a central axis around which the handle means 22 is rotated. Stem portion 24 is tapered inwardly toward its rearward end to a degree corresponding to the taper of the interior of sleeve portion 23 of handle bearing means 19 so that handle means 22 may be inserted within the sleeve portion 23 for rotational movement.
As shown in FIG. 5, the handle means 22 is uniquely formed with the gripping or bar portion 26 offset from the central axis of stem portion 24. The shackle 17 of locking means 16 may be inserted through corresponding shackle openings 28 in the bearing means and 29 in the stem portion of the handle means 22 to a position shown by the heavy lines in FIG. 3. However, the configuration of the handle means noted above permits the padlock 16, in locked condition, to be pivoted upwardly on shackle 17, disposed through the openings 28 and 29, to the position shown by the dotted lines in FIG. 3. The maneuverability of the locking means 16 relative to the handle 22 allowed by the novel configuration of the handle means 22 permits authorized personnel to gain access to the information or secondary access means positioned on the back of the padlock 16.
As shown in FIG. 8, the stem portion 24 of handle means 22, has, at its inward or rearward end, a rectangular boss 30. This boss may be inserted into a corresponding rectangular hole 31 formed in a generally T- shaped latching cam 32. Latching cam 32 is fixedly mounted to handle means 22 over boss 30, in a singlepoint latching system, by a lock washer and cam fastener as shown in FIGS. 6 and 8. Fastening means 40 is inserted into a cored, threaded hole which is bored into the stem portion 24 of handle means 22, as shown in FIG. 5, to assure a positive connection.
In constructing a three-point latching system, on the other hand, an upper latching means or rod 42 and lower latching means or rod 46 are mounted directly on the upper and lower ears of the T-shaped latching cam 32, respectively. These rods are pivotally mounted with respect to the latching cam 32 by pins 39 which permit the latching cam to pivot with respect to the opposite rods 42 and 46, respectively. A cam plate 38 is interposed between the cam fastener 40 and the latching cam 32, before fastener 40 is inserted through opening 31 in latching cam 32 to engage handle means 22. This plate 38 also receives, at its upper and lower ends, the pivot pins 39 to assure that movement of latching cam 32 will always cause generally vertical movement of the upper and lower latching means 42 and 46.
The upper and lower latching means 42 and 46 also have, at their ends opposite the latching cam 32, means for engaging the locker frame 14 to effect a positive latch. For the sake of brevity, only one of these frame engaging latching means will be described in detail here, the opposite, but similar latching arrangement being denoted by prime numerals in the drawing, as shown in FIG. 9. The upper latch means or rod 42 passes through a guide means 45 disposed near its upperend which serves to track the latch means 42 toward a hole formed in the top flange 47 of the door 12. When the door 12 is in closed position, this hole in the flange 47 will be aligned with a corresponding hole formed in the flange 48 of the frame 14. Guided by the guide means 45, the rod passes through an eyelet 44 which is held in position, allowing for a certain amount of play, by a spring clip 43. This enables the connecting rod 42, which is usually displaced somewhat laterally due to the movement caused by rotation of the latching cam 32, to be maintained in a location permitting insertion of the end of the rod 42 through the corresponding aligned openings in the door flange 47 and frame flange ln the operation of the locker handle assembly of this invention with the locking means 16, the shackle 17 of the padlock 16 is removed from openings 28 and 29 to permit rotation of the handle means 22. The handle means 22 may then be turned to rotate the latching cam 32 about the central axis of the stem portion 24 of the handle means 22, causing the stem of the T-portion of the latching means 32 to be removed from corresponding openings formed in the vertical door flange and the frame flange into which it has been inserted to prevent movement of the middle of the door 12 relative to the frame 14. This movement also pulls upper rod 42 downwardly and moves lower rod upwardly to withdraw the ends of these rods into the eyelets 44 and 44' disposed adjacent the upper and lower door flanges 47. Such movement disengages all latching means from the frame and unlatches the door to permit its opening.
Conversely, the rotation of the handle means 22 in the opposite direction will cause the latching cam 32 and upper and lower latching means 42 and 46 to engage the frame 14 and latch the door in a closed position. The shackle 17 of the padlock 16 may then be in-- serted through openings 28 and 29, which are now in aligned position, to prevent further rotation of the handle means 22 and unlatching of the door 12. In such a position, the door will be latched at three points, its mid-portion, its top and its bottom, to securely and effectively maintain it in closed position. It therefore will be able to resist severe abuse and connot be pryed open at the top or bottom to prevent its proper closure, as often happens to present type T-type locker assemblies.
It is recognized that the locker handle assembly 10 of this invention is adaptable to permit use of simply the latching plate 38 and latching cam 32 alone, as described above, so that latching will occur at only the mid-point of the locker door 12. This would be particularly useful in smaller lockers or in those locations in which such lockers are not subject to abuse or attempted break ins.
It is also clear that the latching cam 32 shown in F IG. 2 could be formed so that the extended stem of the T,
when rotated to a latching position, would be positioned behind the flange of the frame 14 to engage the frame 14 and prevent opening of the door. A latching cam in such a reverse S-shaped configuration would effectively latch the door without the necessity of forming corresponding openings in the door and the locker frame.
The materials suitable for construction of the locker handle assembly of this invention include any material which may be easily formed, bored or milled to the required dimensions, but which will endure much abuse and withstand stresses. Such materials include steel and steel alloys, brass and iron.
While this invention has been described in relation to a preferred embodiment thereof, it will be apparent to those skilled in the art that various modifications may be made without departing from the principles of the invention embodied herein. Therefore, only such limitations should be imposed as are indicated by the spirit and scope of the appended claims.
