The storage locker 100 comprises a housing 102 which defines a storage area 106 having an opening 104 at the front of the housing 102. The storage area 106 is shown further divided into a plurality of smaller storage areas used, for example, for storing mail for the multitude of residents in a geographical area. The residents have access to their specific storage area via one of a plurality of mail box doors 130 in the main door 108. Each one of the mail box doors 130 has its own lock. The main door 108 is used for covering the opening 104. In this embodiment, the main door 108 is hinged to the housing 102 with hinge 146. When the main door 108 is in a position where it covers the opening 104, the main door 108 is in the main door closed position.
The storage locker 100 further comprises a lock area 112 which is used to install hardware which will provide a locking function for the main door 108.
FIG. 1 shows the storage locker 100 without the main lock 116 installed in the lock area 112. For some clients, this is the configuration in which the storage locker 100 will be delivered. These clients normally wish to install the main lock 116 themselves.
FIGS. 1 to 3 further show a stop member 120 attached to the back plate 114. In this embodiment, the stop member 120 is a generally S-shaped bracket. A person skilled in the art will understand that the stop member 120 may assume various shapes. For example, the stop member 120 could also be an L-Shaped bracket having an edge welded to the back plate 114. The stop member 120 could also be a C-shaped channel that is either welded or bolted to the back plate 114.
There is further shown on FIGS. 1 to 3, a C-shaped channel 142 which comprises a first extension 122 and a second extension 124. The first extension 122 comprises a slot 138 through which the latch 118 of the lock 116 may travel. This is also shown in FIG. 6.
In FIG. 2, the lock 116 is shown installed on the lock door 126.
Now turning to FIG. 3, the main door 108 of the storage locker 100 is shown in a partially opened position. The lock door 126 for its part is shown approximately half-way to the lock door closed position.
In the embodiments of the invention shown on FIGS. 1 to 4, the lock door 126 is shown to be linked to the back plate 114 through a hinge 144. The lock door 126 is shown as a generally L-shaped channel. The larger surface of the L-shaped channel is for mounting the main lock 116 while the smaller surface of the L-shaped channel closes out the lock area 112 to provide protection from tampering with the main lock 116.
There is also shown on FIGS. 1 to 4 a lock lip 134 which extends from the smaller portion of the L-shaped channel of lock door 126. The lock lip 134 may be useful for interacting with the main door lock edge 110. A handle (not shown) may also be located at a lock edge 110 side of the main door 108. The handle is covered by the lock door 126 when in the lock door closed position.
FIGS. 1 to 4 also show a protection lip 132 which extends from the housing 102 to prevent access to all edges of the main door 108 except for the lock edge 110 which is protected by the lock door 126. The protection lip 132 also extends around a substantial portion of the edges of the back plate 114.
