Abstract: A toy vehicle in the form of a pickup truck on whose rear bed are mounted a pair of miniature dog houses in side-by-side relation, each having a triangular roof hinged to the rear wall of the house. Depending from the front end of each roof is a front wall having an arched opening defining the entry to the dog house which is occupied by a miniature puppy whose head projects through the entry. The puppy is otherwise confined within the doghouse and is removable therefrom only by lifting the roof. To discourage unauthorized removal of a puppy from its doghouse when the toy is on sales display, each roof is provided on its underside with a latching lug having a slot therein aligned with holes in the sidewalls of the dog houses. Insertable into these holes and going through the lugs is a disposable locking pin whose tip is so formed as to frictionally engage the side wall hole in which it is received. Hence to release the roofs and obtain access to the puppies, the pin has to be forcibly pulled out.

A detent is provided for removably maintaining the bolt in locking and releasing positions and a stop member cooperates with the bolt to provide limited movement of the bolt in a lug releasing direction. A manually engageable member is provided on the bolt for actuating the same.

Abstract: A latch for a warewasher effects manual movement of a bolt between a retracted position which permits the door to be fully closed and an extended position which either latchingly engages a keeper to secure the door in the closed position, or abuttingly engages the keeper to prevent the door from being inadvertently fully closed. In addition to manual operation, the latch is operated by gravity to extend the bolt from its retracted to its extended position as the door of the warewasher is moved from a horizontal opened position to a vertical position. In this way, the bolt of the latch is extended to abut the keeper of a warewasher if the door is simply moved from the horizontal opened position to the vertical position, but may be easily and quickly closed by manual operation of the latch to retract the bolt followed by complete closure of the door, and then extension of the bolt to secure the door in the fully-closed position.

Abstract: A locking device for a mobile filing and storage system comprises a reciprocable pin disposed in a rotatable handwheel. The pin is adapted to selectively engage or disengage locking apertures in a stationary plate mounted to the storage frame. The pin is formed with a pair of symmetrical frusto-conical surfaces having apexes that blend into concave surfaces that receive biasing means to retain the pin in the selected engaged or disengaged position against accidental reciprocation of the pin and to provide a tactile feel of proper location in and displacement from the engaged or disengaged position.

Abstract: A sliding door lock in which a bolt is longitudinally slidable by manual movement of a handle to which the bolt is connected so that the bolt is axially rotatable to prevent the cutting of the bolt when locked. The handle slides linearly along a base plate to move the bolt between opened and closed positions. A bullet latch in the handle engages detents on the base plate to hold the handle and bolt in the open and closed positions. A key-operated barrel lock has a barrel groove through which the bolt passes when the lock is in the unlocked position, and the bolt has a circumferential constriction which receives the barrel lock barrel when the barrel lock is rotated to its locked position, thereby preventing movement of the handle and bolt to the open position.

A latching lever, movable between operative and inoperative positions, is secured to a second wedging block which has a wedging surface engageable with the wedging surface of the first wedging block and a bearing surface engageable with the inside surface of the other window panel. In the operative position of the lever, the engagement of the wedging surfaces of the wedging blocks engages the bearing surfaces of the wedging blocks with the inside surfaces of respective window panels to wedge the panels against the bearing surfaces of the support blocks.

Abstract: A flush mountable door lock includes a recessed body member, a lock bolt slidably mounted on the body member, and a paddle-shaped operating handle for moving the bolt. The handle is movable between nested and projected positions. A bolt actuator extends from the handle into a receiving formation provided on the bolt for drivingly interconnecting the handle and the bolt to effect retracting and extending movements of the bolt when the handle is moved toward its projected and retracted positions. A torsion coil spring is interposed between the body member and the handle, and serves the several functions of biasing the handle toward its nested position, maintaining play-free engagement between the handle and the body member when the handle is nested, and maintaining a play-free driving connection between the handle and the bolt when the handle is projected.
