Abstract
Abstract A rod received in a bore formed in the lock mechanism of a rental locked is pressed inwardly upon insertion of a key into a keyhole formed in the front panel of the locker, and a substantially crank-shaped lever is provided to convey this motion of the rod to a swingably mounted shutter, which then opens a coin slot formed in the front panel, the shutter being spring-energized to close the coin slot when the key is pulled out of the keyhole. In another embodiment of the invention, the shutter is made of magnetic material to be moved by an electromagnet which is connected to a switch operated by the aforesaid rod.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
144 words
In a rental locker having a door which can be locked by a key and lock mechanism upon insertion of a coin into a slot, said key being released from said lock mechanism when the door has been locked, the improvement comprising a shutter means mounted swingably within said locker, resilient means continuously urging said shutter means in a direction to close said slot, linkage means in operative contact with said shutter means and extending between said shutter means and said lock mechanism, and means operatively associating said lock mechanism with, said linkage means so that when said key is inserted into said lock mechanism said linkage means is operated to maintain said shutter means away from said slot and when said key is pulled out of said lock mechanism said linkage means is operated to permit said shutter means to close said slot.
Claim 2
Dependent Claim
144 words
In a rental locker having a door which can be locked by a key and lock mechanism upon insertion of a coin into a slot, said key being released from said lock mechanism when the door has been locked, the improvement comprising a shutter means mounted swingably within said locker, resilient means continuously urging said shutter means in a direction to close said slot, linkage means in operative contact with said shutter means and extending between said shutter means and said lock mechanism, and means operatively associating said lock mechanism with, said linkage means so that when said key is inserted into said lock mechanism said linkage means is operated to maintain said shutter means away from said slot and when said key is pulled out of said lock mechanism said linkage means is operated to permit said shutter means to close said slot.
Claim 3
Dependent Claim
75 words
The improvement according to claim 1, in which said linkage means comprises a rod having one end coupled via said operatively associating means to said lock mechanism so that said rod moves back and forth in unison with the movement of said key into and out of said lock mechanism, and a substantially crank-shaped turnable lever having one end thereof in contact with said rod and the other end in contact with said shutter means.
Claim 4
Dependent Claim
152 words
In a rental locker having a door which can be locked by a key and lock mechanism upon insertion of a coin into a slot, said key being released from said lock mechanism when the door has been locked, the improvement comprising a shutter means made of magnetic material mounted swingably within said locker, resilient means continuously urging said shutter means in a direction to close said slot, an electomagnet disposed adjacent said shutter means, switch means connected between said electromagnet and an electrical power supply, and switch-actuating means operatively associating said lock mechanism with said switch means so that when said key is inserted into said lock mechanism said switch means is operated to cause said said shutter means to be maintained away from said slot and when said key is pulled out of said lock mechanism said switch means is operated to permit said shutter means to close said slot.
Claim 5
Dependent Claim
152 words
In a rental locker having a door which can be locked by a key and lock mechanism upon insertion of a coin into a slot, said key being released from said lock mechanism when the door has been locked, the improvement comprising a shutter means made of magnetic material mounted swingably within said locker, resilient means continuously urging said shutter means in a direction to close said slot, an electomagnet disposed adjacent said shutter means, switch means connected between said electromagnet and an electrical power supply, and switch-actuating means operatively associating said lock mechanism with said switch means so that when said key is inserted into said lock mechanism said switch means is operated to cause said said shutter means to be maintained away from said slot and when said key is pulled out of said lock mechanism said switch means is operated to permit said shutter means to close said slot.
Claim 6
Dependent Claim
60 words
The improvement according to claim 3, in which said switch-actuating means comprises a lever swingably connected to a switch box for operating said switch means housed therein, and a rod mounted reciprocably between said lever and said lock mechanism and energized toward the latter, said rod being pressed toward said lever when said key is inserted into said lock mechanism.
Claim 7
Dependent Claim
52 words
The improvement according to claim 3, further comprising a second switch connected between the first mentioned switch and said electrical power supply, said second switch being closed upon closure of said door whereby said eLectromagnet is not energized when said key is inserted into said lock mechanism unless said door is closed.
