Abstract
A locking handle includes a base and a handle rotatably mounted to the base. A well is formed in the handle, and this well communicates with a key opening in a front portion of the handle and a loading opening in a rear portion of the handle. A shaft is mounted in the well via the loading opening to rotate with the handle, and this shaft forms a recess adjacent the key opening. A lock cylinder including a key receiving slot and a locking element is positioned in the recess to rotate in unison with the handle, with the key slot aligned with the key opening. The lock is dimensioned to pass through the loading opening, and the locking element passes outside of the shaft to releasably engage the base and thereby selectably lock the handle against rotation with respect to the base.
Claims9
In a locking handle of the type comprising a base mountable to a mounting surface and a handle rotatably mounted to the base, the improvement comprising:
- a well formed in the handle, said well communicating with a key opening in a front portion of the handle and a loading opening in a rear portion of the handle;
- a shaft mounted in the well via the loading opening to rotate with the handle, said shaft comprising a first part which extends out of the base and a second part which forms a recess adjacent the key opening, said first and second parts of the shaft formed to rotate at all times as a unit;
- a lock comprising a key receiving slot and a locking element;
- said lock positioned in the recess to rotate in unison with the handle with the key slot aligned with the key opening, said lock dimensioned to pass through the loading opening but not the key opening for assembly, said locking element passing outside of the shaft to releasably engage the base and thereby selectably lock the handle against rotation with respect to the base.
In a locking handle of the type comprising a base mountable to a mounting surface and a handle rotatably mounted to the base, the improvement comprising:
- said handle comprising a cylindrical wall extending generally parallel to and spaced from an axis of rotation of the handle, said wall forming a first recess centered on the axis, said first recess communicating with a key opening in a front portion of the handle, said wall comprising a rear surface which forms a loading opening communicating with the first recess;
- a lock comprising a key receiving slot and a locking element;
- a shaft mounted in the recess via the loading opening to rotate with the handle about the axis, said shaft comprising a first part which extends out of the base and a second part which forms a second recess adjacent the key opening, said first and second parts of the shaft formed to rotate at all times as a unit;
- said lock positioned in the first and second recesses, between the handle and the shaft, to rotate in unison with the handle and the shaft, with the key slot aligned with the key opening, said lock dimensioned to pass through the loading opening but not the key opening for assembly, said locking element passing outside the second recess to engage the base and thereby selectably lock the handle against rotation with respect to the base.
