Description

A DOOR LOCK Π7Τ7 Viyjn MUL-T-LOCK LTD., C: 13545 FIELD OF THE INVENTION The present Invention relates to locks generally.
BACKGROUND OF THE INVENTION There exist a great variety of locks, many of them having specialized purposes. Applicant has, In the past, developed locks, particularly suitable for locations In which vandalism Is possible, which are resistant to Inoperablllty caused by the Insertion of foreign matter Into the key slot. One example of such a lock Is described In Israel Patent 96954.
SUMMARY OF THE INVENTION The present inventions seeks to provide an improved door lock particularly suitable for key operation from one side only.
There is thus provided in accordance with a preferred embodiment of the present invention a door lock including a double cylinder housing, a cylinder plug having a key slot formed therein and being disposed in one side of the double cylinder housing, and a manually operable handle member disposed in a second side of the double cylinder housing and having a hollow interior communicating with the key slot of the cylinder plug, such that foreign material introduced into the key slot can be forced therethrough and into the hollow interior.
Additionally in accordance with a preferred embodiment of the invention there is provided a door lock including a double cylinder housing, a cylinder plug having a key slot formed therein and being disposed in one side of the double cylinder housing, and a hollow volume being located at a second side of the double cylinder housing communicating with the key slot of the cylinder plug, such that foreign material introduced into the key slot can be forced therethrough and into the hollow volume.
BRIEF DESCRIPTION OF THE DRAWINGS The present invention will be understood and appreciated more fully from the following detailed description, taken in conjunction with the drawings in which: Fig. 1 is a pictorial illustration of a door lock having foreign matter inserted in the key slot thereof; Fig. 2 is a sectional illustration of a door lock constructed and operative in accordance with a preferred embodiment of the present invention; Fig. 3 is an enlarged pictorial illustration of part of the apparatus of Fig. 2; Fig. 4 is a sectional illustration corresponding to Fig. 2, but showing foreign material being forced out through the key slot; and Fig. 5 is a sectional illustration taken along the lines V - V of Fig. 4.
DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT Reference is now made to Fig. 1, which illustrates a door lock cylinder 10 in the key slot 11 of which foreign matter, such as a matchstick 12, has be inserted, as by an act of vandalism. The present invention seeks to provide a door lock which enables the foreign matter, such as matchstick 12 to be conveniently cleared from the key slot 11, without requiring removal of the cylinder from the door or other disassembly.
Reference is now made to Figs. 2 - 5, which illustrate a door lock constructed and operative in accordance with a preferred embodiment of the present invention and including a two sided cylinder housing 20 having a lock cylinder 22 disposed in one side thereof and a manually operable lock handle assembly 24 disposed in engagement with the other side thereof.
Lock cylinder 22 may be any conventional lock cylinder suitable for disposition in a two-sided cylinder housing and has a key slot 26 with which communicate a plurality of locking pins 28.
Disposed at the interior end of lock cylinder 22 is a key operated locking assembly, which is seen particularly in Fig. 3 and includes a key engagement member 30, whose inward displacement is limited by a limiting bar 32, which is fixedly seated across the key slot 26 in lock cylinder 22. Key engagement member 30 is normally maintained in spaced relationship with respect to limiting bar 32 by a compression spring 34, as seen in Fig. 2.
Compression spring 34 is disposed between key engagement member 30 and an axial pin assembly 36, which includes an axially extending pin 38, a retaining ring 40 and a compression spring 42, normally retaining the pin 38 in a retracted position with respect to retaining ring 40, such that pin 38 does not normally operatively engage a yoke member 44. The relative positions of the various elements of key operated locking assembly in the absence of insertion of a key in key slot 26 are illustrated in Fig. 2, which also shows the presence of foreign matter such as a matchstick 46 in the key slot 26.
As seen in Fig. 2, the cylinder 22 is retained in cylinder housing 20 by means of a conventional retaining ring 48, while handle assembly 24 is retained therein by a conventional retaining ring 50. It is seen that handle assembly 24 operatively engages yoke 44 for rotation thereof by means of a protrusion 54 which engages a corresponding slot 56 in yoke 44.
It is a particular feature of the present invention that handle assembly 24 is formed with a generally hollow portion 52, which communicates with the interior of the key slot 26, so as to permit foreign matter which has been placed in the key slot 26 to be forced out through the key slot 26 into the interior of hollow portion 52, as illustrated generally in Fig. 4.
It may be appreciated from a consideration of Figs. 3 and 4, that when a key 60 is fully inserted into the key slot 26, as illustrated in Fig. 4, the forward edge of the key displaces key engagement member 30 axially until it engages limiting bar 32. This forward axial movement compresses spring 34 and forces pin 38 axially forward through retaining ring 40, while compressing spring 42. The extension of pin 38 axially forward brings it into operative engagement with a correspondingly shaped recess 66 (Fig. 3) formed in yoke 44, such that rotation of key 60 produces rotation of cylinder 22 and corresponding rotation of thus operatively engaged pin 38 and yoke 44, thereby providing locking operation.
Fig. 4 also illustrates how the forward edge of key 60 is operative to force foreign material such as matchstick 46 out of the key slot 26, alongside limiting bar 32 and into the hollow volume defined by hollow portion 52. It is noted that when necessary, accumulated foreign material inside portion 52 may be removed either by removing a handle element 68 therefrom or by removing handle assembly 24 from cylinder housing 20 as by disengagement of retaining ring 50.
It will be appreciated by persons skilled in the art that the present invention is not limited by what has been particularly shown and described hereinabove. Rather the scope of the present invention is defined only by the claims which follow:

Claims (5)
