Abstract

A slidably lockable bracket having two levels and a keyhole aperture with a slot running from the upper level to the lower level and an enlarged aperture at the end of the slot at the upper level. A sliding member having a post and an enlarged head is engaged and locked in the bracket by inserting the head through the enlarged aperture, sliding the post along the slot, and dropping the head in the lower portion, thereby locking the head on the lower level. Preferably the lower level is configured to retain the head.

Claims

1. A slidably lockable bracket for a sliding member having a substantially cylindrical post having a post diameter and a head having a head height and a head diameter, attached to one end of said post, said head diameter being greater than said post diameter, comprising:

a base having a keyhole aperture, which keyhole aperture has;

a circular portion having a diameter greater than said head diameter; and

an elongated slot having a width intermediate between said post diameter and said head diameter extending away from said circular portion;

attachment means for attaching said base substantially parallel to a surface wherein said circular portion is spaced apart from said surface by a first distance greater than said head height; and

said base having a recess at a recessed end of said slot opposite said circular portion, said recessed end of said slot being recessed away from said surface by a second distance greater than said first distance and said recess being adapted to receive said head, wherein;

said base has a plurality of edges and said attachment means comprises a plurality of side members, each attached to one of said edges.

2. A bracket according to claim 1, wherein said recessed portion and said surface are parallel and define a maximum distance between said base and said surface, and wherein said side members have a height substantially equal to said maximum distance.

4. A bracket according to any one of claims, 1, 2 or 3, wherein:

said sides are integrally formed with said base.

5. A bracket according to any one of claims 1, 2 or 3, wherein:

said walls and sides are formed of metal.

3. A slidably lockable bracket for a sliding member having a substantially cylindrical post having a post diameter and a head having a head height and a head diameter, attached to one end of said post, said head diameter being greater than said post diameter, comprising:

a base having a keyhole aperture, which keyhole aperture has;

a circular portion having a diameter greater than said head diameter; and

an elongated slot having a width intermediate between said post diameter and said head diameter extending away from said circular portion;

attachment means for attaching said base substantially parallel to a surface wherein said circular portion is spaced apart from said surface by a first distance greater than said head height; and

said base having a recess at a recessed end of said slot opposite said circular portion, said recessed end of said slot being recessed away from said surface by a second distance greater than said first distance and said recess being adapted to receive said head, wherein;

said base has a first end adjacent to said circular portion of said keyhole aperture, a second end adjacent to said recess, and two elongated edges extending from said first end to said second end; and

said attachment means comprises;

first and second sides, each having a head portion of a first height and a recess portion of a second height, said first height being greater than said head height, said second height being greater than said first height, and said head portion of said first and second sides being attached to both of said edges near said first end and said recess portion of both of said sides being attached to both of said edges near said second end.
