Abstract
Abstract A fastening clip for securing articles together, the clip including releasably connected male and female components. The male component comprises a pin and the female component comprises a retainer for releasably clamping the pin. When joined, the pin cannot be separated from the retainer except by a specially formed tool which is insertable in the retainer. Manipulation of the tool serves to condition the retainer for removal of the pin. In a modified form of the invention, the retainer is of magnetic material, and an actuating tool including an electromagnet is employed to actuate the retainer and permit removal of the pin.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
227 words
A fastening clip for securing two or more articles together comprising: a. a generally cylindrical housing the inner wall at one end of which is tapered to form a conical bore at such one end thereof, b. a retainer loosely received entirely within said housing, said retainer including an upper portion of reduced outer diameter, a central cylindrical section having a diameter slightly less than the inside diameter of said housing so as to guide said retainer during movement thereof, and a lower section formed with a conical exterior surface adapted to mate with said tapered wall of said housing, an axial bore extending entirely through said retainer, and at least one transverse opening formed in said lower section of said retainer, said opening being of relatively greater dimension than said axial opening, c. a plurality of retaining balls positioned in said transverse opening and adapted to engage said tapered wall and intersect said axial bore, d. spring means disposed around said upper portion of said retainer for resiliently biasing said retainer toward said tapered wall of said housing thereby biasing said balls toward said axial bore, and e. pin means extending upwardly into said axial bore and tightly frictionally engaged by said retaining balls, any attempted withdrawal of said pin from said retainer serving to increase the frictional force on said pin exerted by said balls.
Claim 2
Dependent Claim
227 words
A fastening clip for securing two or more articles together comprising: a. a generally cylindrical housing the inner wall at one end of which is tapered to form a conical bore at such one end thereof, b. a retainer loosely received entirely within said housing, said retainer including an upper portion of reduced outer diameter, a central cylindrical section having a diameter slightly less than the inside diameter of said housing so as to guide said retainer during movement thereof, and a lower section formed with a conical exterior surface adapted to mate with said tapered wall of said housing, an axial bore extending entirely through said retainer, and at least one transverse opening formed in said lower section of said retainer, said opening being of relatively greater dimension than said axial opening, c. a plurality of retaining balls positioned in said transverse opening and adapted to engage said tapered wall and intersect said axial bore, d. spring means disposed around said upper portion of said retainer for resiliently biasing said retainer toward said tapered wall of said housing thereby biasing said balls toward said axial bore, and e. pin means extending upwardly into said axial bore and tightly frictionally engaged by said retaining balls, any attempted withdrawal of said pin from said retainer serving to increase the frictional force on said pin exerted by said balls.
Claim 3
Dependent Claim
80 words
The fastening clip of claim 1 further including a retaining ring mounted in said housing adjacent the upper end thereof, the inner diameter of said ring being not greater than the inner diameter of said upper portion of said retainer to prevent effective access to the adjacent end of said retainer for manipulating the same relative to said housing, said resilient biasing means being disposed around said upper portion of said retainer and urging the latter downwardly in the housing.
Claim 4
Dependent Claim
27 words
The fastening clip of claim 1 wherein said retainer is constructed of magnetized material for actuation by a magnet positioned adjacent the upper end of the clip.
Claim 5
Dependent Claim
35 words
The fastening clip of claim 1 wherein said transverse opening formed in said lower section of said retainer extends transversely entirely through said retainer, with a pair of balls being disposed in such transverse opening.
