Abstract

Abstract A security device for protecting equipment such as typewriters, calculators and the like comprises a flexible pad bondable by adhesive to a mounting surface such as a table or desk, and a cover having depending lugs having holes adapted to register with corresponding loop devices protruding upward from the pad so that lock pins may be passed through the lugs and loops, from openings through the cover, to attach the cover to the pad. Locks are provided to be inserted into the openings after the lock pins have thus been introduced so that the pins cannot be retracted until the locks are unlocked by a key. Means is provided for bolting the equipment to the top of the cover from inside the cover before the cover is attached to the pad. Thus there is no access to the bolts holding the equipment until the locks are removed. The bonding adhesive is so strong in tension that a person cannot lift it off the mounting base. The pad can be removed from the mounting base however after the cover is unlocked and removed, by peeling the pad off the the base.

Claim 2
Dependent Claim 140 words
An equipment mounting security device comprising an adhesive pad adapted to be adhered to a mounting surface, a cover assembly adapted to cover the adhesive pad so that said pad is essentially exposed only to said mounting surface and the underside of said cover, means within the cover lockably attaching the cover assembly to the pad, means for attaching an equipment to the outside of said cover from a position within the cover between the cover and the pad and accessible only when said cover assembly is unlocked and separated from the pad, said adhesive pad when adhered to a mounting surface requiring many times the amount of force in tension or shear to separate the pad from the surface than the amount of force required to separate the pad from the surface by peeling the pad from the surface.
Claim 3
Dependent Claim 186 words
An equipment security device comprising: a pad having a top surface and a bottom surface; an adhesive layer attached to said bottom surface for adhering said pad to a mounting base; first fastening means secured to said top surface; a cover plate having an upper surface and a lower surface, adapted to cover said pad; equipment attaching means for attaching to said upper surface an equipment to be protected, said equipment attaching means being detachable from the equipment only from said lower surface; second fastening means secured to said lower surface; engaging means holding said first fastening means and said second fastening means together so that the cover cannot be removed from the pad; and lock means posiTioned at the cover plate to prevent disengagement of the engaging means when the lock means is locked, said adhesive layer being characterized by requiring, when adhered to such mounting base, many times the amount of force in tension and in shear to separate the pad from the base than the amount of force required to separate the pad from the base by peeling the pad from the base.
Claim 4
Dependent Claim 186 words
An equipment security device comprising: a pad having a top surface and a bottom surface; an adhesive layer attached to said bottom surface for adhering said pad to a mounting base; first fastening means secured to said top surface; a cover plate having an upper surface and a lower surface, adapted to cover said pad; equipment attaching means for attaching to said upper surface an equipment to be protected, said equipment attaching means being detachable from the equipment only from said lower surface; second fastening means secured to said lower surface; engaging means holding said first fastening means and said second fastening means together so that the cover cannot be removed from the pad; and lock means posiTioned at the cover plate to prevent disengagement of the engaging means when the lock means is locked, said adhesive layer being characterized by requiring, when adhered to such mounting base, many times the amount of force in tension and in shear to separate the pad from the base than the amount of force required to separate the pad from the base by peeling the pad from the base.
Claim 5
Dependent Claim 53 words
A device according to claim 2 in which the first fastening means comprises a loop means and the attaching means comprises a passage means which registers with the loop means when the cover plate covers said pad and the engaging means is a device which engages said loop means and said passage means.
Claim 6
Dependent Claim 60 words
A device according to claim 3 in which the engaging means comprises a pin means and the loop means comprises a first passageway means and the passage means comprises a second passageway means which registers with the first passageway means when the cover plate covers the pad, the pin being dimensioned to fit through said first and second passageway means.
Claim 7
Dependent Claim 34 words
A device according to claim 4 in which each passageway means comprises a plurality of passageways spaced apart and the pin means comprises as many pins as the number of passageways of the pad.
Claim 8
Dependent Claim 13 words
A device according to claim 2 in which the adhesive is heat sensitive.
Claim 9
Dependent Claim 16 words
A device according to claim 2 in which the adhesive is heat sensitive and pressure sensitive.
Claim 10
Dependent Claim 48 words
A device according to claim 2 in which said first fastening means comprises a plate secured to said top surface by adhesive having characteristics similar to the adhesive layer attached at said bottom surface of the pad and the loop means comprises loops rising from said plate means.
