A security apparatus for securing a portable electronic device to an immovable object includes a locking head having a base and a compressible element supported by the base. The locking head is adjustable between an unlocked configuration, in which the compressible element is uncompressed and insertable into and removable from an opening of the portable electronic device, and a locked configuration, in which the compressible element is compressed and secured within the opening of the portable electronic device.

A lock comprises a male element, and a female element for receiving the male element enabling aligned copular engagement. The male element has a shoulder and the female element a catch for closing behind the shoulder to hold the male element therein. The catch and a lock casing are held in the female element with the axis of the lock casing inclined, normally at a right angle, to the line of engagement of the male and female elements. The lock casing and the female element have juxtaposed faces inclined to the line of engagement of the male and female elements. At least one face on the lock casing extends from the casing outwardly from the line of engagement contiguous with an inwardly facing complementary face on the female element. In this way longitudinal forces generated by attempted separation of the engaged male and female elements are resolved by said faces into a lateral force on the female element.

Examples of a computing system having a lock port for a cable-lock unit are described. In an example, a computing system includes a control unit, a receptacle electrically coupled to the control unit, a lock port to receive a cable-lock unit to lock the computing system at a location, a lock engagement member, and a plug coupled to the lock engagement member. The lock engagement member and the plug are to translate and form an electrical connection between the plug and the receptacle in response to receiving the cable-lock unit in the lock port. The control unit is to determine presence of the cable-lock unit in the lock port in response to formation of the electrical connection between the plug and the receptacle.

A lock for securing a portable device is disclosed. The lock can be inserted into a cavity. The cavity has a first sidewall and a second sidewall both of which extend away from an opening into the cavity with a gradually increasing distance between the two sidewalls for a section of the two sidewalls. The lock for securing a portable device comprises a lock body; a first engaging member projecting from the lock body and having an outside part outside the lock body, a cross-sectional area of the outside part of the first engaging member being substantially the same or become larger from a front end towards a rear end of the outside part of the first engaging member; and a second engaging member, connected to the lock body and configured to move along a side of or across the first engaging member to insert into the cavity for a locking status and to withdraw from the cavity for an unlocking status.

A security apparatus for securing a portable electronic device to an immovable object includes a head having a base. The head also includes a plurality of engagement elements extending from the base and configured to be inserted into an aperture of the portable electronic device. The plurality of engagement elements is movable relative to the body while inserted into the aperture to engage a portion of the portable electronic device. The head further includes a linear element positioned between the plurality of engagement elements. The linear element is movable relative to the plurality of engagement elements to push the plurality of engagement elements radially outward. The security apparatus also includes a security device attached to the head and configured to engage the immovable object.

The present invention relates to a bicycle lock comprising a lock body and set of arms. The lock body is mountable on the seat of the bicycle. The arms extend from the lock body and terminate in locking surfaces. The locking surfaces are secured together by a locking element. The lock body and arms comprise an integrated textile fabric and steel cable structure simultaneously resistant to common sawing and slicing attacks. The lock body secures the bicycle seat while the arms are threaded through and around bicycle components to attach to a stationary object.

A lock that is configured to be attached to electronic equipment requiring securing against theft and the lock comprising: a lock body; a locking element protruding from the lock body and having a forward distal section that is comparatively wider in cross-sectional size compared to a rear section thereof, the forward section being configured to be insertable into a cavity formed in the equipment, where the cavity is defined by an opening having a size and shape slightly larger than the cross-sectional size of the forward section of the locking element and an interior larger in cross-sectional size than the opening of the cavity; a slidable locking pin configured to slide alongside the locking element and into the cavity, after the locking element has been inserted into said cavity, to substantially fill a space of the cavity left unoccupied by the locking element; a sliding mechanism coupled to the locking pin and configured to slide the locking pin into and out of the cavity; and a locking mechanism to lock the locking mechanism within the lock body to prevent withdrawal of the locking element from the cavity.

A buckle comprising a male coupler including a bar portion with an external surface, a first flange protruding from the external surface, the first flange being adapted for connection of a strap thereto; a female coupler with a hollow body having an opening therein, the opening including an end part at a first axial end of the hollow body and a slot part extending generally axially from the end part of the opening, the slot part having opposing lips extending along the slot, the hollow body having an internal surface complementary to the external surface of the bar portion; a detent for releasably holding the bar portion in the hollow body; and wherein the lips extend reentrantly and each lip is adjacent a respective inwardly-extending face in the bar portion.

A helmet locking system utilizing an arrangement of two enlarged members, a pass-through locking member, and a length of cable. A fixed enlarged member is permanently mounted to the cable and a detachable enlarged member engages with the pass-through locking member which is positioned on the cable's end opposite to the fixed enlarged member. The locking system does not require keys or a combination. Pass-through locking member is threaded through the D-ring of a helmet. Detachable enlarged member is then then fixedly fitted onto the pass-through locking member. The detachable enlarged member is then placed into a motorcycle's storage compartment which is then closed and locked thereby securing the helmet to the motorcycle.

Embodiments of the present invention are directed to merchandise display systems and methods for displaying an article of merchandise. In one example, the system includes a sensor configured to be secured to the article of merchandise. The sensor includes a first engagement member. The system also includes a base configured to removably support the sensor thereon. The base includes a second engagement member configured to releasably engage the first engagement member such that the sensor is locked to the base. The sensor is configured to rotate with respect to the base while locked thereto.
