Connecting device for easy connection of separate casings for electric apparatus
First Claim
1. A connecting device for detachably connecting a first casing with a second casing, comprising:
- first and second wedges disposed on said first casing;
a third wedge secured to said second casing;
a fourth wedge slidably mounted on said second casing;
at least said second and fourth wedges being substantially parallel with each other when said first and second casings are in a mating position;
means for driving said fourth wedge on said second casing, said driving means comprising a link assembly which is operatively coupled with said fourth wedge; and
means for locking said fourth wedge at a locking position where said fourth wedge is engaged with said second wedge of said first casing;
wherein said link assembly comprises;
a first link rotatably mounted on said second casing; and
a second link connected, at one end thereof, with said first link and, at the other end thereof, with said fourth wedge;
wherein, when said first and second casings mate with each other and said link assembly is operated in one direction, said fourth wedge moves from a first position where said fourth wedge is located remotest from said second wedge, through a second position where said fourth wedge is located closest to said second wedge to be engaged therewith, into a third position where said fourth wedge is located between said first and second positions but still engaged with said second wedge.

Abstract
A connecting device for detachably connecting two separate casings, includes a first movable engaging member slidable on a first casing, a second stationary engaging member secured to the second casing, and a link assembly operatively connected to the first engaging member. An actuator handle is operatively connected to the link assembly. A stopper is provided for locking a movement of the actuator handle. When the actuator handle is operated in one direction, the first engaging member is moved through the link assembly toward the second engaging member so as to be engaged with the second engaging member. When the actuator handle is operated in the other direction, the first engaging member is moved through the link assembly remote from the second engaging member so as to be disengaged from the second engaging member.
