Lever lock for display structures

摘要

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.

1. 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; wherein the linkage includes a scotch yoke operable to convert the rotation of the lever into an axial translation, the scotch yoke including: a sliding yoke slidably disposed within the body, the sliding yoke including a pin slot extending in a direction perpendicular to an axis of the shaft; and a pin connected to the lever and extending parallel to an axis of rotation of the lever so as to move about an arc with the rotation of the lever, the pin being disposed in the pin slot of the sliding yoke and operable to move the sliding yoke through the translation as the pin moves about the arc.
