In a shelf apparatus for a showcase, which is provided with a shelf support for supporting a shelf plate on which commodities are placed so as to be slidable in a depth direction, the shelf apparatus is constructed so that the shelf support is provided with a locking plate extending in a width direction of the shelf plate, and the shelf plate is provided with a hooking member which is formed with a steel rod member which extends in the depth direction and whose rear portion further extends along the locking plate on a back surface side of the shelf plate, and also which enables the rear portion to be locked to and unlocked from the locking plate by being swayed vertically. When the shelf plate is held on the shelf supports, the rear portion of the hooking member is locked to the locking plate. By doing this, the shelf plate does not slide forward. When the shelf plate is pulled out forward, the hooking member is unlocked from the locking plate by being swayed vertically. By doing this, the shelf plate can be pulled out forward.

An overrunning coupling assembly includes a notch plate and an annular coupling pocket plate positioned in face-to-face relationship with respect to each other along a common axis. The pocket plate has strut pockets disposed at angularly spaced positions about the common axis. The notch plate has notch recesses at angularly spaced positions about the common axis and positioned in juxtaposed relationship with respect to the strut pockets. Torque-transmitting struts are positioned in each of the strut pockets. Each strut has first and second ears at one edge thereof for enabling pivotal motion of the struts about an ear axis intersecting the ears. The opposite edge of each strut is movable between disengaged and engaged positions with respect to one of the notch recesses whereby one-way torque transfer may occur between the plates. A lubricant flows between the notch plate and pocket plate. A spring is positioned in each strut pocket and biases the respective strut toward the notch plate. Each spring engages the respective strut intermediate the ear axis and the opposite edge. Each strut pocket provides sufficient clearance forward of the respective opposite edge of the strut to allow forward sliding movement of the respective strut during overrunning to cause the engagement of the respective spring and strut to occur nearer the ear axis, thereby reducing the length of a moment arm about which the spring acts upon the strut which enables frictional forces of the flowing lubricant to hold the strut in its disengaged position to prevent the strut from slapping against the notch recesses as the notch plate and pocket plate are respectively counterrotated.

Locking and blocking devices for USB ports include a lock having a linear cam with a lock button at its back end, and a locking member pivotally connected at its back end to a retaining sheath such that forward sliding of the linear cam pivots the locking member outwards.

A firearm handguard having two identical halves, or half guards, can engage the barrel nut of certain firearms to thereby provide a mounting rail system. The barrel nut attaches the barrel to the receiver. The half guards can be separately positioned in engagement with the barrel nut before fastening them together. The fastening operation can cause the half guards to clamp onto the barrel nut. Alternatively, the front handguard cup of some firearms can prevent the handguard from slipping forward while the rear barrel nut engagement prevents handguard rotation. Free floating variants, however, must clamp onto the barrel nut.
