Abstract
Abstract This invention relates to a locking device comprising a latch arm of resilient stretchable material adapted to be pivotally mounted at one end to one element. The latch arm has a handle at its free end and has an enlarged portion positioned inwardly of such handle and formed integrally therewith, the enlarged portion being adapted releasably to engage a retaining portion formed integrally with a retainer bracket secured to another element adjacent the first element, a secure substantially vibration free connection of the two elements being formed when the resilient latch arm is stretched to enable the enlarged portion to engage the retaining portion.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
136 words
A locking device comprising a latch arm of resilient stretchable material having a hub at one end and a handle at its other end, a substantially U-shaped mounting bracket having a base and a pair of spaced parallel legs each with a hole therethrough, said holes being transversely aligned, said hub having a transverse bore therethrough, a pin extending through said bore and said holes pivotally to mount the hub end of said latch arm to said mounting bracket, a retainer member having a retaining portion, locking means formed integrally with said latch arm, releasably to engage said retaining portion, said hub having a radially projecting portion formed integrally therewith extending at right angles to the latch arm and of length such as to resiliently engage said base when said locking means engages said retaining portion.
Claim 2
Dependent Claim
136 words
A locking device comprising a latch arm of resilient stretchable material having a hub at one end and a handle at its other end, a substantially U-shaped mounting bracket having a base and a pair of spaced parallel legs each with a hole therethrough, said holes being transversely aligned, said hub having a transverse bore therethrough, a pin extending through said bore and said holes pivotally to mount the hub end of said latch arm to said mounting bracket, a retainer member having a retaining portion, locking means formed integrally with said latch arm, releasably to engage said retaining portion, said hub having a radially projecting portion formed integrally therewith extending at right angles to the latch arm and of length such as to resiliently engage said base when said locking means engages said retaining portion.
Claim 3
Dependent Claim
143 words
A locking device comprising a latch arm of resilient stretchable material having a hub at one end and a handle at its other end, a substantially U-shaped mounting bracket having a base and a pair of spaced parallel legs each with a hole therethrough, said holes being transversely aligned, said hub having a transverse bore therethrough, a pin extending through said bore and said holes pivotally to mount the hub end of said latch arm to said mounting bracket, a retainer member having a retaining portion, locking means formed integrally with said latch arm, releasably to engage said retaining portion, said hub having a radially extending portion trapezoidal in cross section extending at right angles to the latch arm and of length substantially equal to the distance between the axis of the bore of said hub and the adjacent surface of said base.
Claim 4
Dependent Claim
143 words
A locking device comprising a latch arm of resilient stretchable material having a hub at one end and a handle at its other end, a substantially U-shaped mounting bracket having a base and a pair of spaced parallel legs each with a hole therethrough, said holes being transversely aligned, said hub having a transverse bore therethrough, a pin extending through said bore and said holes pivotally to mount the hub end of said latch arm to said mounting bracket, a retainer member having a retaining portion, locking means formed integrally with said latch arm, releasably to engage said retaining portion, said hub having a radially extending portion trapezoidal in cross section extending at right angles to the latch arm and of length substantially equal to the distance between the axis of the bore of said hub and the adjacent surface of said base.
Claim 5
Dependent Claim
214 words
A locking device comprising a latch arm of resilient stretchable material having a hub at one end and a handle at its other end, a mounting bracket, means pivotally mounting the hub end of said latch arm to said mounting bracket an L-shaped retainer bracket having a mounting leg, means to mount said mounting leg to extend at right angles to the pivotal mount of said hub, said bracket having a retaining leg extending at right angles to said mounting leg, said retaining leg being conformed to define a socket and having a central rectangular slot extending downwardly from its upper edge through the central part of said socket, the lower edge of said slot defining an abutment, locking means comprising a ball conformation formed integrally with said latch arm adjacent the handle and adapted to be accommodated in said socket releasably to engage the latter, with the latch arm resting on said abutment defined by the lower edge of said slot, said latch arm having a pivot member formed integral therewith and extending outwardly from the inner surface thereof at right angles thereto, between the hub and the ball conformation, the free end of said pivot member engaging the mounting leg of said retainer bracket when the latch arm is in locked position.
Claim 6
Dependent Claim
214 words
A locking device comprising a latch arm of resilient stretchable material having a hub at one end and a handle at its other end, a mounting bracket, means pivotally mounting the hub end of said latch arm to said mounting bracket an L-shaped retainer bracket having a mounting leg, means to mount said mounting leg to extend at right angles to the pivotal mount of said hub, said bracket having a retaining leg extending at right angles to said mounting leg, said retaining leg being conformed to define a socket and having a central rectangular slot extending downwardly from its upper edge through the central part of said socket, the lower edge of said slot defining an abutment, locking means comprising a ball conformation formed integrally with said latch arm adjacent the handle and adapted to be accommodated in said socket releasably to engage the latter, with the latch arm resting on said abutment defined by the lower edge of said slot, said latch arm having a pivot member formed integral therewith and extending outwardly from the inner surface thereof at right angles thereto, between the hub and the ball conformation, the free end of said pivot member engaging the mounting leg of said retainer bracket when the latch arm is in locked position.
