Abstract

A lever lock is used for attaching first and second support elements in a display structure. The lever lock includes a body that attaches to a side of the first support element. A shaft extends from the body and is oriented to pass through the slot. A foot is disposed at an end of the shaft that is remote from the body and is configured to operatively engage a side of the second support element so as to provide a clamping force on the second support element against the first support element. A lever is coupled to the body and configured to rotate between first and second positions. A linkage connecting the lever with the shaft converts the rotation of the lever into a movement of the shaft through a translation and axial rotation so as to move the foot between engaging and disengaging positions.

Claims20

Dependent claims

A lever lock for attaching first and second support elements in a display structure, the first support element including a first side having a slot disposed therein and the second support element including a second side having another slot disposed therein, the lever lock comprising:

a body including an attachment for securing the body to the first side of the first support element;
a shaft extending from the body and oriented with respect to the attachment of the body to pass through the slot of the first support element;
a foot disposed at an end of the shaft that is remote from the body, the foot being configured to operatively engage the second side of the second support element so as to provide a clamping force on the second support element against the first support element;
a lever coupled to the body and configured to rotate between first and second positions;
and
a linkage connecting the lever with the shaft, the linkage being operable to convert the rotation of the lever between the first and second positions to a movement of the shaft through a translation along an axis of the shaft and a rotation about the axis of the shaft so as to move the foot between engaging and disengaging positions.

3 more elements

An assembly comprising:

a first support element including a first surface having a first slot disposed therein;
a second support element including a second surface having a second slot disposed therein;
and
a lever lock attaching the first and second support elements, the lever lock including a body with an attachment secured to the first side of the first support element about the first slot, a shaft extending from the body through the first slot of the first support element, a foot disposed at an end of the shaft that engages the second slot of the second support element and provides a clamping force on the second support element against the first support element, and a lever coupled to the body and configured to release the attachment of the second support element to the first support element by rotating the shaft and moving the foot of the shaft away from the second slot of the second support element upon movement of the lever to an open position.
