Abstract: An anti-theft device for computers and the like having a housing with side-walls. The device comprises a block-shaped casing having a front surface, a lock member selectively projectable or withdrawable from the front surface and a key-operated lockable device effective to lock the lock member in the projected position thereof. At least a first hook-shaped projection is provided at the front surface located at one side of the projectable lock member. A cable is fixable to the casing at one end, and to an immovable object at the other end thereof. The first hook-shaped projection is adapted to be inserted into a first opening formed in a side-wall of the housing and then displaced so that the locking device becomes hooked to the housing, in which position the projectable lock member is inserted into an opening formed in the side-wall to prevent the separation of the first projection from the computer housing. A pair of hook shaped projections may be employed.

Abstract: An improved locking device especially for portable computers of the type comprising a lock casing connectable on the one hand to an immovable object by a safety cable, and on the other hand to the protected object intermediate a designated slot formed in a side wall of the computer. The improvement consists of a yoke-member which comprises a first portion configured to be in the engaged state, entrapped between the lock casing and the side wall. A second portion of the yoke member bridges over the lock casing, forming an enclosed hollow thereunder through which electric cables of auxiliary equipment such as mouse and keyboard are passed.

Abstract: A method of storing a plurality of objects being of an identical prismatic shape and stored within an open top storage container in an up-right, compact side-by-side relationship. Each object is placed forming an acute angle with respect to both adjacent objects, so that one corner portion thereof projects from between the adjacent objects and hence is easily accessible for retrieval from the container. The container has a bottom, side-walls and an open top for storing objects having an identical prismatic shape. The bottom of the container is formed so as to staggerly recline each object in relative opposite directions.

Abstract: An arrangement for arresting a portable object, such as a desk computer, to a stationary object using a cable (40), one end of which is looped around the stationary object. The other end of the cable (40) is secured to a block-like cable-shoe body (44). An oblong circular cavity (46) is formed in the body (44) with an undercut portion (48) extending along about 180 degrees of one side thereof. Further provided is a lock member (10) having a ribbed attachment portion (24). The attachment portion (24) comprises a recess (26) defined between first and second ribs (28; 30) and is adapted to be inserted into the cavity (46) and shifted into engagement with the undercut portion (48), and then locked thereinside by push-in key operated device (50). Said lock member (10), with ribbed attachment portion (24) is affixed to a side wall of the portable object in various conventional manners.

Abstract: A screw having a screw-threaded shank and a circular head, the head being provided with three radially extending screwdriver tip receiving portions defined between three first, off central integrally formed projections designed to become shaved-off the screw head by a pre-set force applied during tightening of the screw, and three second, integrally formed projections designed to withstand a shear force greater than the pre-set force applied during slackening of the screw.

Abstract: An anti-theft device (10) for portable computers having a base casing (12) and a hingeable cover (14). One wall of the base casing (14) is formed with a dedicated slot (16). The device (10) is generally U-shaped, having two legs (20; 22), and a web portion (24). The device (10) comprises a rotatable locking mechanism (26) installed within the web portion (24), drivingly coupled to a T-shaped tip (28) adapted to be inserted into the slot (16) in one position of the mechanism and, by rotating the mechanism by less than 180°, the tip (28) becomes locked within the base casing (12) while the legs (20; 22) extend one (22) underlying the bottom surface of the base casing (12) and the other (20) overlying the top surface of the hingeable cover (14), thus preventing the opening of the cover. A cable is used for securing the device (10) to a stationary object (32).

Abstract: A screw (10) having a screw-threaded shank (14) and a circular head (12), the head being provided with three radially extending screwdriver tip receiving portions (16; 18; 20) defined between three first, off-central integrally formed projections (16a; 18a; 20a) designed to become shaved-off the screw head by a pre-set shear force applied during tightening of the screw, and three second, integrally formed projections (16c; 18c; 20c) designed to withstand a shear force greater than the said pre-set force applied during slackening of the screw.

Abstract: A locking arrangement for locking a portable article (16) such as miniature computer processor having a planar flat bottom surface to a stationary object such as table surface (10). At least a pair of first protrusions (22a-22d) are provided, each forming an undercut with respect to the bottom surface of the portable article (16), and an opening (24). A bar shaped locking substrate member (26) is provided comprising a bottom surface adapted to be placed on and fastened to the stationary object (10), and a top surface with at-least a pair of complementary undercut portions (32a-32d) configured to frictionally match the first protrusions (22a-22d) when the article is positioned overlapping the substrate member (26). Further provided is a key-operable rotatable lock member (36) carrying a projection (40) which is adapted to become inserted into the opening (24) in the overlapping position to thereby arrest the portable article (16) against the substrate member (10).

Abstract: A protection device (16) particularly for portable computers (10) having a Universal Serial Bus (USB) socket (12) and a standardized dedicated slot (14) formed in vicinity of the socket (12). A key or the like operable mechanism (18) is provided for rotating a T-shaped tip member (20) which is adapted to be inserted into and locked by the slot (14). Plug (22) may be either a “demo” or part of an active device, which functions to enable/disable the operation of the computer. The device (16) may further be provided with arresting means in the form of a cable (24), which can be tied to an immovable object such as table leg (26) for protecting the computer (10) against theft.
