Abstract
Abstract A recessed slider mount is formed on the top of a support structure for holding a slider placed upside down with its pull tab received in a channel extending downwardly therefrom. A lever turnably supported between a pair of brackets formed on one side of the support structure includes a detent formed on its upper end to engage the opening of the pull tab and hence to lock the slider in position on the slider mount. Any accidental unlocking of the slider is prevented as by means including a second lever turnably supported adjacent the lower end of the first recited lever and urged by a spring to have one end thereof normally held opposite to an abutment formed on the support structure. Hence, unless the second lever is turned to move the said one end thereof away from its position opposite to the abutment, the first lever cannot be turned to unlock the slider.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
156 words
A device for holding a slider during assemblage of a fastener chain therethrough, wherein said slider includes a pull tab having an opening therein, said device comprising: a support structure including: a recessed slider mount formed on the top of said support structure, and a channel extending downwardly from said recessed slider mount, said channel being adapted to receive said pull tab of said slider placed upside down on said recessed slider mount; a lever supported by said support structure so as to be turnable between a first and a second position; a detent formed on the upper end of said lever and adapted to engage said opening of said pull tab when said lever is in said first position; spring means for yieldably urging said lever to said first position; and means for normally preventing said lever from turning to said second position where said detent is disengaged from said opening of said pull tab.
Claim 2
Independent Claim
156 words
A device for holding a slider during assemblage of a fastener chain therethrough, wherein said slider includes a pull tab having an opening therein, said device comprising: a support structure including: a recessed slider mount formed on the top of said support structure, and a channel extending downwardly from said recessed slider mount, said channel being adapted to receive said pull tab of said slider placed upside down on said recessed slider mount; a lever supported by said support structure so as to be turnable between a first and a second position; a detent formed on the upper end of said lever and adapted to engage said opening of said pull tab when said lever is in said first position; spring means for yieldably urging said lever to said first position; and means for normally preventing said lever from turning to said second position where said detent is disengaged from said opening of said pull tab.
Claim 3
Dependent Claim
139 words
A device for holding a slider as defined in claim 1, wherein said means comprises: a second lever supported adjacent the lower end of the first mentioned lever so as to be turnable between a first and a second position; an abutment formed on said support structure so as to face one end of said second lever with a spacing therebetween when the latter is in said first position; and second spring means for normally holding said second lever in said first position; said second lever being turnable to said second position against the tension of said second spring means to cause said one end thereof to move away from its position opposite to said abutment whereby the first mentioned lever is permitted to turn to said second position thereof against the tension of the first mentioned spring means.
Claim 4
Dependent Claim
29 words
A device for holding a slider as defined in claim 2, wherein the tension of said second spring means is smaller than that of the first mentioned spring means.
Claim 5
Dependent Claim
175 words
A device for holding a slider as defined in claim 1, wherein said means comprises: a stop member turnably supported at one end thereof adjacent the lower end of said lever, the other end of said stop member extending laterally from said lever and being positioned opposite to said support structure; a push rod slidably extending transversely of the lower end portion of said lever, said push rod including: a larger diameter portion formed on one end thereof and adapted to be received in an aperture formed transversely of said support structure, a smaller diameter portion formed intermediate between both ends of said push rod, and a sloping step formed between said larger and said smaller diameter portions; spring means for yieldably urging said other end of said stop member against said larger diameter portion of said push rod to prevent said lever from turning to said second position; and second spring means for normally holding said push rod in such a position that said larger diameter portion thereof is partly received in said aperture.
Claim 6
Dependent Claim
28 words
A device for holding a slider as defined in claim 4, including a knob formed on the other end of said push rod to manually press the same.
Claim 7
Dependent Claim
28 words
A device for holding a slider as defined in claim 4 wherein the tension of said second spring means is smaller than that of said first spring means.
