DETAILED DESCRIPTION

[0033] The following description is merely exemplary in nature and is not intended to limit the present disclosure, its application or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

[0034] A cabinet, in accordance with a non-limiting example, is indicated at 10 in FIG. 1. Cabinet 10 includes a bottom wall 12, a top wall 14, a first side wall 16, a second or opposing side wall 18 and a third side wall 19. Third side wall 19 extends between and connects with first side wall 16 and second side wall 18. A door 20 including a latch 22 is pivotally mounted to cabinet 10. Together door 20, bottom wall 12, top wall 14, first side wall 16, second side wall 18, and third side wall 19 define a storage volume 23. A plurality of wheels indicated generally at 25 are mounted to bottom wall 12 so as to allow cabinet 10 to be mobile.

[0035] In accordance with a non-limiting example, cabinet 10 includes a lock opening 25 formed in second side wall 18 adjacent a door frame 28 as shown in FIG. 2. Lock opening 25 takes the form of a slot 30 having an upper end 32 and a lower end 34. While shown as a slot, it will become more fully evident herein that the geometry of lock opening 25 may vary. Cabinet 10 includes a locking system 38 including a lock element 40 and a lock mechanism 46 (FIG. 3). Locking system 38 allows a user to secure cabinet 10 with a cable 50 in a public space without the need for any additional keys. That is, lock mechanism 46 is only accessible from within storage volume 23. Thus, as long as the user can open door(s) 20, lock mechanism 46 can be accessed as will become more fully apparent herein.

[0036] As shown in FIG. 2, lock element 40 includes a generally rectangular cross-section having a substantially planar surface 56 defining an upper edge 58 and a lower edge 60. Substantially planar surface 56 defines a first side surface 62, while an opposing substantially planar surface (not separately labeled) defines a second, opposing side surface 64. Lock element 40 includes a latch receiver 68 that extends from upper edge 58 into first side surface 62 and second side surface 64 defining a notch (not separately labeled) the particular shape and dimensions of latch receiver 68 may vary. Upper edge 58 includes a first angled section 72 and lower edge 60 includes a second angled section 74. First angled section 72 and second angled section 74 facilitate insertion of lock element 40 into lock openings 25. Lock element 40 is further shown to include a cable opening 80 for connecting with cable 50.

[0037] Reference will now follow to FIG. 3 with continued reference to FIGS. 1 and 2 in describing lock mechanism 46 in accordance with a non-limiting example. Lock mechanism 46 includes a first guide element 90 arranged adjacent to upper end 32 of slot 30 and a second guide element 92 arranged adjacent to lower end 34 of slot 30. First guide element 90, and second guide element 92 together with first angled section 72 and second angled section 74 facilitate insertion of lock element 40 into slot 30. Lock mechanism 46 also includes a latch and release mechanism 98 that is mounted in storage volume 23 and selectively engages with lock element 40. Latch and release mechanism 98 includes a first end 102 which, in the non-limiting example shown, may be mounted to first guide element 90, a second, cantilevered end 104 defining a release handle (not separately labeled) and an intermediate portion 106. A lock pin 108 projects outwardly from intermediate portion 106 and may selectively rest in latch receiver 68. Lock pin 108 may extend through an opening 111 formed in a lock pin guide 112.

[0038] In a non-limiting example, cable 50 may include an end loop (not shown) and be passed around a post 55. Lock element 40 may be passed through the end loop and guided into slot 30. First end section 72 and/or second angled section 74 may interact with first guide element 90 and/or second guide element 92. As lock element 40 moves into slot 30, first angled section 72 acts on lock pin 108 to raise latch and release mechanism 98. With continued insertion, lock pin 108 will settle into latch receiver 68 effectively locking cabinet 10 to the post. Locking may occur with or without access to storage volume 23. To release, a user must access storage volume 23 and engage with latch and release mechanism 98 to raise lock pin 108 out from latch receiver 68. At this point, lock element 40 may be withdrawn from slot 30.

[0039] Reference will now follow to FIGS. 4 and 5, with continued reference to FIGS. 1 and 3 in describing a lock element 122 in accordance with another non-limiting example. Lock element 122 includes a generally rectangular cross-section having a substantially planar surface 124 defining an upper edge 128, and a lower edge 130. Substantially planar surface 124 defines a first side surface 132 while an opposing second substantially planar surface (not separately labeled) defines a second, opposing side surface 134. A latch receiver 138 extends from upper edge 128 into first side surface 132 and second side surface 134. Upper edge 128 includes a first angled section 140 and lower edge 130 includes a second angled section 142. A cable opening 146 extends through lock element 122.

[0040] In accordance with a non-limiting example, lock element 122 includes a lock opening cover or shield 148. Lock opening cover 148 projects outwardly of upper edge 128, lower edge 130, first side surface 132, and second side surface 134 as shown in FIG. 5. Lock opening cover 148 prevents unwanted access of lock opening 25 when lock element 122 is installed. In this manner, lock element 122 provides an added level of tamper-proof securing for locking system 38.

[0041] FIGS. 6 and 7 depicts a lock element 160 in accordance with another non-limiting example. Lock element 160 includes a substantially circular cross-section having an outer surface 162 that extends between a first end 164 and a second end 166. A latch receiver 168 is defined in outer surface 162. Latch receiver 168 may take the form of an annular recess 170. Second end 166 may include a taper 173 that facilitates insertion into a corresponding lock opening (not shown). First end 164 includes a cable support 179 that may connect with cable 50. A lock opening cover 182 projects radially outwardly of outer surface 162 between latch receiver 168 and cable support 179. Lock opening cover 182, in a manner similar to that described herein, prevents unwanted access of the lock opening when lock element 160 is installed.

[0042] At this point, it should be understood that the locking system is not limited to the examples shown. That is, in addition to a latch dropping under force of gravity to place a lock pin in a latch pin receiver, springs may be used to urge a latch upwardly or to one side or another. Further, the particular geometry of the lock opening and the lock elements may vary as well as the location of both the lock and lock opening may vary. The non-limiting examples shown present a system for locking a cabinet or other structure without the need for additional keys or to memorize combinations. The latch is only accessible once the cabinet doors are unlocked and open.

[0043] While the above disclosure has been described with reference to exemplary embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from its scope. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the disclosure without departing from the essential scope thereof. Therefore, it is intended that the present disclosure not be limited to the particular embodiments disclosed, but will include all embodiments falling within the scope thereof
