Fastener for holding items to a perforated wall

A method for mounting an item holder to the front surface of a perforated wall having front and rear surfaces and having spaced holes therein, the item holder having a base with front and rear surfaces and with a rear hook-like member extending therefrom, a rear projection having a displaceable portion, and a camming member having at least a portion extending along, and rotatable about, an axis oriented in a front-to-rear direction relative to said base, said method comprising:

• placing the item holder on the wall by inserting the hook-like member into a first hole of a perforated wall to which said item holder is to be mounted;
• inserting the rear projection into a second hole of the perforated wall to which said item holder is to be mounted;
• and
• rotating the camming member about said axis to effect displacement of the displaceable portion of the rear projection to move it laterally of the second hole.

A method for mounting an item holder to the front surface of a perforated wall having front and rear surfaces and having spaced holes therein, the item holder having a base with a rear hook-like member extending therefrom, a rear projection having a displaceable portion, and a rotatable camming member comprising a shaft, said method comprising:

• placing the item holder on the wall by inserting the hook-like member into a first hole;
• inserting the projection into a second hole;
• selectively rotating the shaft to effect displacement of the displaceable portion of the rear projection to move it laterally of the second hole;
• and
• selectively rotating the shaft to release displacement of the displaceable portion for removal of the projection from the second hole.

An item holder in combination with a perfboard having regularly spaced holes, said item holder comprising:

• a base having a front side and a rear side;
• an item holding component on said front side;
• a fastener projecting from said base rear side, said fastener insertable into and removable from one of said holes in said perfboard, said fastener having spaced fingers each including a proximal portion closest to said base and a distal displaceable end portion adapted to be movable laterally relative to said proximal portion, said fastener having a passageway extending axially of said projecting fastener;
• and
• a shaft rotatable in said passageway, said shaft comprising an end portion for engaging and moving said displaceable end portions laterally relative to said proximal portions upon rotation of said shaft.

An item holder in combination with a perfboard having regularly spaced holes, said item holder comprising:

• a base having a front side and a rear side;
• an item holding component on said front side;
• a fastener projecting from said base rear side, said fastener adapted to be inserted into and removed from one of said holes in said perfboard, said fastener having a portion thereof adapted to extend beyond the hole of the perfboard, said projection portion being displaceable laterally of the hole to resist movement of said fastener and said base in a rear-to-front direction, said fastener having a passageway extending axially of said projecting fastener;
• and
• a shaft rotatable in said passageway for engaging and moving said displaceable projection portion laterally upon rotation of said shaft.
