Abstract
Abstract On strap connectors wherein the prongs of a male member are inserted into pockets of the female member and are held in place by a rocking shaft in notches in the prongs, which rocking shaft is cut away so that it can be turned out of said notches into an out of the way position for releasing the prongs, and wherein a manipulating lever is provided for rocking said shaft into and out of the notches of said prongs, and wherein also gas pressure actuated means are provided for rocking the shaft into prong releasing position, and wherein a locking lever is provided to prevent the manipulation of said manipulating lever, a gas actuated plunger having a projection bearing against said locking lever and actuated simultaneously with the gas actuated rocking of said shaft, for pushing the locking lever into releasing position.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
199 words
In a strap connector having a female member with a transverse hole in which a rocking shaft is rockable into and out of releasing position relatively to male prongs of a male member inserted into said female member so as to intersect said hole, said rocking shaft being adapted to release said prongs when rocked from an initial locking position into a releasing position, and having a manipulating lever for manually rocking said rocking shaft and having a locking lever to lock said manipulating lever in prong locking position, a device actuated by a pressure medium for rocking said shaft into releasing position, and means to conduct said pressure medium to said device, the improvement of an anxiliary pressure actuated device for moving said locking lever into releasing position comprising, an element in said female body related to said locking lever and being movable to shift said locking lever from locking position into releasing position, and means actuated by the same pressure medium which actuates said pressure actuated shaft rocking means to move said movable member for shifting said locking member into releasing position substantially simultaneously with the pressure actuated rocking of said rocking shaft into prong releasing position.
Claim 2
Dependent Claim
199 words
In a strap connector having a female member with a transverse hole in which a rocking shaft is rockable into and out of releasing position relatively to male prongs of a male member inserted into said female member so as to intersect said hole, said rocking shaft being adapted to release said prongs when rocked from an initial locking position into a releasing position, and having a manipulating lever for manually rocking said rocking shaft and having a locking lever to lock said manipulating lever in prong locking position, a device actuated by a pressure medium for rocking said shaft into releasing position, and means to conduct said pressure medium to said device, the improvement of an anxiliary pressure actuated device for moving said locking lever into releasing position comprising, an element in said female body related to said locking lever and being movable to shift said locking lever from locking position into releasing position, and means actuated by the same pressure medium which actuates said pressure actuated shaft rocking means to move said movable member for shifting said locking member into releasing position substantially simultaneously with the pressure actuated rocking of said rocking shaft into prong releasing position.
Claim 3
Dependent Claim
28 words
The device specified in claim 1, and said movable member being a reciprocating element, and said gas actuated auxiliary means being a plunger to reciprocate said movable element.
Claim 4
Dependent Claim
74 words
The device specified in claim 1, and said movable member being a plunger stem bearing against said locking lever in locking position, said auxiliary pressure medium actuated device including a plunger on said stem reciprocable in a cylinder chamber in said female member, an intake in the end of said cylindrical chamber adjacent said plunger, and means to connect said intake with the pressure medium supply to said pressure medium actuated shaft rocking device.
