Abstract: A release sleeve used with quick connect tube connectors includes a plurality of planar surfaces at an outer peripheral surface which bias retainer legs radially outwardly to allow removal of a tube. The use of planar surfaces provides a greater contact area than prior art release sleeves, thus reducing the amount of force necessary to allow tube removal. In a further feature of the present invention, the release sleeve has grooves at an outer peripheral surface which allow passage of indicator legs such that the release sleeve may be used in combination with an indicator used to give an indication that a tube is fully connected.

Abstract: A locking pin assembly for sliding members comprises a member having bifurcated portions insertable within a hole extending through the sliding members. The bifurcated portions are adapted to be cammed apart by a bar supported for slidable movement within the bifurcated portions thereby securely wedging the pin in the hole and locking the sliding members together. In one preferred embodiment, the bifurcated portions are supported in a sleeve and are joined to a handle portion extending through the other end of the sleeve. Actuation between a locked and unlocked position is effected by movement of the sleeve relative to the handle portion. In an alternative embodiment, the camming bar is omitted, and locking action is carried out instead by causing slidable movement of one wedging portion relative to another.

Abstract: A conversion apparatus has a magnetic latching solenoid equipped with a special plunger shaft and piston mechanism which can move independently of the plunger, allowing mechanical locks to operate with momentary battery power. The plunger shaft is bored to accept the piston which consists of an inner shaft and a locking pin. The locking pin and inner shaft are secured to the plunger shaft with a light spring. With this mechanism, the operation of locking and unlocking is complete, regardless of readiness of the locking device, since the locking pin will move to the intended position of locking/unlocking after momentary prevention such as premature twisting of the lock knob.
