Toggle clamp with locking mechanism

Abstract

The invention discloses a toggle clamp with a locking mechanism. According to the invention, a toggle clamp locking mechanism for selectively coupling a work piece. The mechanism includes a base structure; a primary locking system movement between a retaining position and a release position, the primary locking system having a handle member pivotally coupled to the base structure, an action for engaging the workpiece in the retaining position and releasing the workpiece in the release position, and a linkage system mechanically interconnecting the handle member with the action. A second locking system having an engagement member is provided having a cam follower cammingly engaging a first detent when the primary locking system is in the retaining position preventing the primary locking system from moving from the retaining position. The second locking system is actuatable to disengage the cam follower from the first detent to enable movement of the primary locking system to move from the retaining position.

The entire disclosure of the above application is incorporated herein by reference. technical field [0003] The present disclosure relates to toggle clamps, and more particularly, to toggle clamps having locking mechanisms. Background technique [0004] This section provides background information related to the present disclosure which is not necessarily prior art. [0005] Toggle clamps are used for various purposes such as holding and / or securing workpieces. A conventional toggle clamp includes a clamp body that can be secured to a workstation or other support structure. The retaining arm is pivotally connected to the clamp body to allow articulation of the retaining arm relative to the normally stationary clamp body. A c...

Problems solved by technology

However, traditional toggle locks have at least two major disadvantages

The first disadvantage is that excessive vibration or shock can cause the center pivot to move from its over center position, thus "not locking" the mechanism

A second disadvantage (and potentially more general) is that the gripper can be inadvertently actuated by inadvertently touching the actuator

They often require the operator to activate them through clumsy or inappropriate movements that cannot be integrated into normal and conscious grip activities
