Abstract
A clamp device for securing the housing of PC's and similar equipment to a desk or table so that it can not be moved or stolen. The device is shaped to fit on the PC housing. Clamp pieces at the rear are made to grip the PC at its back by insertion of a wrench or screwdriver in sockets which drive threaded rods. Rotation of the rods causes the rear clamps to move forward or rearward. A key locking means at the front of the device, is used to block access to the clamp adjustment sockets, preventing the clamp from being removed from the PC. In addition, provision is made for insertion of blocking bars in the device frame, so that access to the PC disk drives can be denied.
Claims16
A clamp locking device comprising:
- a frame constructed from metal channel and formed to fit a PC, said frame having two parallel arms and a front portion, said parallel arms being made long enough to project along a PC housing side and beyond its back plane, said frame front portion being made long enough to enable said frame to fit snugly around a PC housing;
- a clamp adjusting means mounted inside each arm of said frame;
- a pair of clamp pieces, with each clamp piece operatively connected to said clamp adjusting means so as to be operated by said adjusting means, and projecting perpendicularly to said arms and in the plane of said arms;
- said clamp pieces mounted in a manner permitting longitudinal movement along said frame arms;
- a disk drive blocking means, said blocking means including a blocking rod which is inserted vertically in the front portion of said frame when required to block access to the PC disk drive;
- said blocking means alternately including a U-shaped bar which may be inserted vertically in the front portion of said frame;
- and
- a locking means mounted inside the front of said frame, said locking means when open, permitting access to said clamp adjustment means for tightening or loosening said clamp pieces;
- said locking means when closed, holding said disk drive blocking means secured and preventing access to said clamp adjustment means.

- a clamp adjusting means mounted inside each arm of said frame;
- a back clamp bar, operatively connected to said clamp adjusting means so as to be operated by said adjusting means, and projecting perpendicularly to said arms and in the plane of said arms;
- said back clamp bar connected at its ends and permitting only longitudinal movement along said frame arms;
- a disk drive blocking means, said blocking means including a blocking rod which is inserted vertically in the front portion of said frame when required to block access to the PC disk drive;
- said blocking means alternately including a U-shaped bar which may be inserted vertically in the front portion of said frame;
- and
- a locking means mounted inside the front of said frame, said locking means when open, permitting access to said clamp adjustment means for tightening or loosening said back clamp bar;
- said locking means when closed, holding said disk drive blocking means secured and preventing access to said clamp adjustment means.

A device for blocking access to disk drives, said device comprising:
- a frame constructed from metal channel;
- a locking means mounted inside said frame;
- and
- a disk drive blocking means;
- said frame having two holes bored vertically in it and located to accommodate said blocking means;
- said frame having adhesive means attached to one surface for attaching said frame to a PC housing;
- said disk drive blocking means including a rod which is inserted vertically in said frame when required to block said disk drives;
- said blocking means also including a U-shaped bar which may be inserted vertically in said frame;
- said locking means including a cylinder lock combined with a slide bar and return spring;
- said cylinder lock being fixedly secured to said frame, and having said slide bar located in said frame in a manner to bear against the projections of said lock and against said return spring;
- said slide bar having two cutout holes bored through it and spaced apart to accommodate the legs of said U-shaped blocking bar;
- said locking means being actuated by movement of a key in said cylinder lock, causing said lock projections to force said slide bar to slide in said frame a distance sufficient for the edge of each said cutout hole to engage and retain said blocking rod or said U-shaped blocking bar, locking it in place and blocking access to said disk drives.
