Locking apparatus for floor mount connector

摘要

Apparatus for blocking the release of a surgical table from engagement with a floor bracket is provided. In a surgical table having a foot lever which actuates a bar to cause the release of connecting means from a tongue of a floor bracket, a vertical pin is provided on the bar. A base plate having a slot therein is provided on the lower portion of the surgical table adjacent to the pin. A blocking plunger of a first pulling solenoid may be extended across the slot to block the movement of the pin to prevent the displacement of the bar and the release of the connecting means from the tongue. The extension of the blocking plunger is caused by the retraction of an extension plunger of a second solenoid, which extension plunger is parallel to but disposed above the blocking plunger and is connected to the blocking plunger by a connecting block. The extension of the blocking plunger causes a cam surface on the connecting block to engage a cam follower to actuate a microswitch which produces a signal indicating the blocking of the pin. The blocking plunger may be retracted from its blocking position by being retracted by the first solenoid to free the pin and allow release of the surgical table from the floor bracket.
