Adjustable, releasable binding fastener
First Claim
1. A releasable fastener for binding a stack of paper, comprising:
- a female fastener portion having a first planar base including an aperture therethrough, and further having an arcuate shaped collar extending perpendicularly from said first planar base, said collar comprised of a pair of opposing, parallel collar halves positioned on opposing sides of the aperture, each of the collar halves including a vertical, first series of ratchet teeth facing the aperture; and
a male fastener portion having a second planar base, and a rod-like post extending perpendicularly from said second planar base, said post having an exterior surface having two vertical oppositely disposed second series of ratchet teeth oriented to engage said first series of ratchet teeth when said post is inserted between said arcuate shaped collar and towards said aperture, in a ratchet manner when the first and the second series of ratchet teeth are mutually engaged.

Abstract
A fastening device has male and female portions, the male portion having a base and a downwardly extending post with two vertical series of horizontal ratchet teeth, one on each side of the post, and two convex lobes extending outwardly in diametrically opposing positions between the two vertical series of ratchet teeth. The female portion has a base and an upwardly extending collar consisting of two curved halves. Each collar half has a series of horizontal ratchet teeth on its inner surface. The circular space defined by the collar halves continues through an aperture in the base. The ratchet teeth may also continue on the inside wall of the aperture. To assemble the fastener the collar of the female portion is placed into a binding hole in a stack of paper, and the post of the male portion is placed into the opposite side of the binding hole, with its base mutually aligned with the base of the female portion. The post is pushed manually into the collar, where its teeth lock with the teeth in the collar. To disassemble the fastener, the opposing bases are rotated until the teeth disengage, and the portions can be withdrawn from each other and removed from the stack.

20. A releasable fastener for binding a stack of paper, comprising:
-
a female fastener portion having a first planar base including a slot of extended length therethrough, and a collar including a pair of sides extending perpendicularly from said first planar base, said pair of sides in opposing relationship and separated by said slot, each of the sides including a vertical, first series of parallel ratchet teeth sloping toward the slot; a male fastener portion having a second planar base, and a post extending perpendicularly from said second planar base, said post having a pair of oppositely disposed exterior surfaces each having a vertical second series of parallel ratchet teeth oriented to engage said first series of parallel ratchet teeth when said post is inserted between said pair of sides of said collar in a ratchet manner when the first and the second series of ratchet teeth are parallel and are mutually engaged. - View Dependent Claims (21, 22, 23, 24)

25. A releasable fastener for binding a stack of paper, comprising:
-
a male portion having a first planar base and a plurality of male posts perpendicularly supported by said first planar base, each post having an exterior surface having two vertical, oppositely disposed first series of ratchet teeth; and a plurality of female fastener portions, each having a second planar base including an aperture therethrough, and having a female collar perpindicular to said planar base, each female collar including a pair of collar halves, the collar halves positioned on opposing sides of said aperture, each of the collar halves including a vertical, second series ratchet teeth facing the series of ratchet teeth on the other collar half and on opposite sides of said aperture, and oriented to engage said first series of ratchet teeth of one of said male posts when one of said male posts and said collar are engaged.
