This invention discloses a high strength security lock cylinder. The lock cylinder includes a front lock housing, a front lock plug, a rear lock housing, a rear lock plug, a horizontal bar, and a lock cam. The front and rear lock plugs are connected with the lock cam and can drive the lock cam to rotate. An electronic locking mechanism is placed inside the front lock plug. The rear lock plug is connected with an axel, which is connected with a knob that contains a digital control board and an electrical power source. A signal transmission channel is formed along the horizontal bar for transmitting signals between the electronic locking mechanism and the digital control board. The lock cylinder is flexible, strong, and resistant to drilling and lock picking and it can be digitally controlled. This reduces the security risks caused by misplacement or unauthorized use of keys.

A vehicle assembly includes a vehicle body and a driver seat. The vehicle body defines a driver compartment having a first door with a first window and a second door with a second window. The driver seat is disposed within the driver compartment. When the driver seat is in a position that accommodates an operator being in a 95.sup.th male height percentile, the operator within the driver seat can see out of (i) the first window at a first angle relative to a forward looking direction that is parallel with a longitudinal axis of the vehicle body and (ii) the second window at a second angle relative to the forward looking direction. Each of the first angle and the second angle is at least 95 degrees.

A lock including a set of tumblers preserving their position after contact with a key to permit blocking of the keyhole during the opening process.

The invention relates to a key (1) for locking a lock, comprising at least one first surface (2) and at least one second surface (2′), with at least one sensing position (4) provided along the longitudinal extent of the key (1), at which sensing position on the first surface (2) at least one first code (3) is provided for reading in the lock and/or at least one second code (3′) is provided on the second surface (2′) for reading in the lock, wherein at least one code (3) of the first surface (2) differs at least at one sensing position (4) from the second code (3′) at the same sensing position (4). The invention furthermore relates to a lock for a key of this type, and a system made up of at least two locks or lock groups and at least one key according to the invention.

A key cylinder device includes a key cylinder attached inside a cylinder portion of a cylindrical mounting member and locked/unlocked by a mechanical key, and a packing insertion portion that is integrally formed on an outer surface of the key cylinder so as to have a shape without an undercut portion and includes an opening for insertion of a packing member in a vertical direction along the outer surface.

A key cylinder device includes a rotor resiliently mounting tumblers that are aligned by insertion of a mechanical key, a rotor case rotatably housing the rotor that is inserted in a direction opposite to an insertion direction of the mechanical key, and a cylindrical sleeve arranged around an outer peripheral surface of the rotor and fixed to an inner surface of the rotor case. The sleeve includes a hole that allows the tumblers to be disengaged when the mechanical key is inserted and to be engaged when the mechanical key is extracted.

The present invention discloses a trailer lock including a lock bar and a cylinder connected with the lock bar, wherein the cylinder includes an outer casing, a plug casing mounted at a front end of the outer casing and a plug provided in a middle of the plug casing, and further includes a bolt casing fixed in the outer casing and a cam accommodated in the bolt casing and connected with the plug, a telescopic core is provided in the cam, telescopic bolts for fixing the lock bar are provided at two sides of the bolt casing, the bolt has a front end connected with a rear end of the cam, and the lock bar has a front end provided with a press head having an annular neck where the bolt is clamped. The trailer lock designed in this way is convenient to use.

A weather resistant pin lock with an elongated body, defining a longitudinal axis includes a shell housing a rotatable core having a keyway. An elevated pinway projects upwardly from the shell to define a linear array of pin slots containing a set of lock pins. A hood is fastened to the pinway to hold the lock pins in the pin slots and to provide a water resistant barrier. A drainway provides a channel for water to flow outwardly from the interior of the shell, the rotatable core and the keyway within the core, to a drain below the pin lock. At the proximate end, an access door rotates adjacent the keyway at an elevated position, to provide a gap along the bottom edge of the access door.

The present disclosure provides for a lock cylinder having a rotatable spindle with at least one disc and at least one wafer housing rotatingly engaged therewith. A slidable wafer is carried on the wafer housing. A locking bar is operable to prevent rotation of the lock cylinder in a locked position and permit rotation of the lock cylinder in an unlocked position.

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 system also includes a base configured to removably support the sensor thereon. The base includes a lock mechanism configured to lock the sensor to the base.
