Fastener receptacle having press-in mounting

Claim 2

An improved fastener receptacle which is useful in providing protection against dust, weather and radiofrequency leakage for use in a quick release fastener of the type having an interengageable fastener receptacle and fastener stud with the stud having a head and a dependent shank with a spiral cam slot formed with a locking shoulder extending inwardly from the lower end thereof, said fastener receptacle comprising: an enclosing casing having a cylindrical side wall formed with a serrated toothed shoulder and a groove and rib immediately adjacent thereto providing a self-clinching press-in mounting at the inner end of the cylindrical wall, said casing having a sealing cap enclosing the outer end of the cylindrical wall; and locking means engageable with the spiral cam slot of the stud disposed within the casing and shiftable longitudinally thereof and normally urged towards the upper end thereof by means of a helical spring disposed within the casing whereby the locking means may shift downwardly against the force exerted by the spring when it is engaged by the spiral cam slot of a fastener stud.

Claim 3

An improved fastener receptacle which is useful in providing protection against dust, weather and radiofrequency leakage for use in a quick release fastener of the type having an interengageable fastener receptacle and fastener stud with the stud having a head and a dependent shank with a spiral cam slot formed with a locking shoulder extending inwardly from the lower end thereof, said fastener receptacle comprising: an enclosing metallic casing having a cylindrical side wall with a pair of diametrically opposed longitudinal extending slots formed therein near the outer end thereof and with a serrated toothed shoulder and a groove and rib immediately adjacent thereto providing a self-clinching press-in mounting at the inner end of the cylindrical wall, said casing having a sealing cap enclosing the outer end of the cylindrical wall and extending over the slots formed therein; locking means having projecting portions disposed in the slots in the wall so as to be shiftable longitudinally of the slots when engaged by the spiral cam slot of a fastener stud; and a helical spring disposed within the casing and extending between the shoulder in the side wall and the locking means to normally press the locking means toward the outer end of the slots whereby the locking means may shift downwardly in the slots against the force exerted by the spring when the locking means is engaged by the spiral cam slot of a fastener stud.

Claim 4

An improved fastener receptacle which is useful in providing protection against dust, weather and radiofrequency leakage for use in a quick release fastener of the type having an interengageable fastener receptacle and fastener stud with the stud having a head and a dependent shank with a spiral cam slot formed with a locking shoulder extending inwardly from the lower end thereof, said fastener receptacle comprising: an enclosing metallic casing having a cylindrical side wall with a pair of diametrically opposed longitudinal extending slots formed therein near the outer end thereof and with a serrated toothed shoulder and a groove and rib immediately adjacent thereto providing a self-clinching press-in mounting at the inner end of the cylindrical wall, said casing having a sealing cap enclosing the outer end of the cylindrical wall and extending over the slots formed therein; locking means having projecting portions disposed in the slots in the wall so as to be shiftable longitudinally of the slots when engaged by the spiral cam slot of a fastener stud; and a helical spring disposed within the casing and extending between the shoulder in the side wall and the locking means to normally press the locking means toward the outer end of the slots whereby the locking means may shift downwardly in the slots against the force exerted by the spring when the locking means is engaged by the spiral cam slot of a fastener stud.

Claim 5

An improved fastener receptacle as set forth in claim 2 in which spacing means are provided between the top of the cap and the cylindrical side wall to provide clearance for the end of a fastener stud when it is rotated between locked and unlocked positions.

Claim 6

An improved fastener receptacle as set forth in claim 3 in which the slots in the cylindrical side wall extend to the upper end thereof and the spacing means consists of a ring disposed around the inside of the cap beyond the cylindrical wall so as to close the ends of the said slots.

Claim 7

An improved fastener receptacle as set forth in claim 2 in which the slots in the cylindrical side wall terminate in enlarged openings in the outer end of the wall and the top of the cap is formed with indentations which are disposed in the enlarged openings and close the end of the slots, the indentations serving as guides to indicate the rotary orientation of the receptacle.

Claim 8

A quick release fastener useful in providing protection against dust and weather and radiofrequency leakage which comprises: (a) a spiral slot fastener stud having a head and a dependent shank with a spiral cam slot having a locking shoulder extending inwardly from the lower end thereof; and (b) a fastener receptacle for interengagement with the fastener stud and having (i) an enclosing metallic casing having a cylindrical side wall with a pair of diametrically opposed slots extending longitudinally near the outer end thereof and with a serrated toothed shoulder and a groove and rib immediately adjacent thereto providing a self-clinching press-in mounting at the inner end of the cylindrical wall, said casing having a sealing cap enclosing the outer end of the cylindrical wall and extending over the slots formed therein; (ii) a locking pin extending diametrically across the cylindrical wall with its ends disposed in the slots in the wall so as to be shiftable longitudinally of the slots when engaged by the spiral cam slot of the fastener stud; (iii) and a helical spring disposed within the casing and extending between the shoulder in the side wall and the locking pin to normally press the pin toward the outer end of the slots whereby the pin may shift downwardly in the slots against the force exerted by the spring when the pin is engaged by the spiral cam slot of the fastener stud.

Claim 9

A quick release fastener useful in providing protection against dust and weather and radiofrequency leakage which comprises: (a) a spiral slot fastener stud having a head and a dependent shank with a spiral cam slot having a locking shoulder extending inwardly from the lower end thereof; and (b) a fastener receptacle for interengagement with the fastener stud and having (i) an enclosing metallic casing having a cylindrical side wall with a pair of diametrically opposed slots extending longitudinally near the outer end thereof and with a serrated toothed shoulder and a groove and rib immediately adjacent thereto providing a self-clinching press-in mounting at the inner end of the cylindrical wall, said casing having a sealing cap enclosing the outer end of the cylindrical wall and extending over the slots formed therein; (ii) a locking pin extending diametrically across the cylindrical wall with its ends disposed in the slots in the wall so as to be shiftable longitudinally of the slots when engaged by the spiral cam slot of the fastener stud; (iii) and a helical spring disposed within the casing and extending between the shoulder in the side wall and the locking pin to normally press the pin toward the outer end of the slots whereby the pin may shift downwardly in the slots against the force exerted by the spring when the pin is engaged by the spiral cam slot of the fastener stud.
