Abstract: A device is provided for use in actuating a locking lug in a cylindrical lockset. The device includes a mechanism for moving the locking device between door handle locking and unlocking positions. The moving mechanism includes a plunger having an axis, a locking-assist spring coupled to the plunger and the locking lug, and a mechanism for reciprocating the plunger along its axis in opposite directions. To lock the cylindrical lockset, the reciprocating mechanism moves the plunger along its axis in a locking direction against the locking-assist spring so that the locking-assist spring is moved toward the locking lug to urge the locking lug to its door handle-locking position. To unlock the cylindrical lockset, the reciprocating mechanism moves the plunger along its axis in an opposite, unlocking direction away from the locking lug so that the locking lug is allowed to move to its door handle-unlocking position.

Abstract: The security tag (10) has a housing (11) and a clasp (12), which can move longitudinally therein, in the manner of a padlock. In its closed position, a piston (20), which is prestressed by a spring (21), engages into a gap or interruption (15) in the clasp (12). In order to open the clasp (12), a reduced-pressure source, which raises the piston (20), is placed onto a projection (28), so that the said piston releases the clasp (12). The use of a reduced-pressure source exacerbates the unauthorized opening of the security tag.

Abstract: An infant-restraining protective seat (1) includes a seat back (3) tiltably attached to the body (7) of a seat portion via a turning shaft (20), with the seat portion (2) and seat back (3) being foldable. A torsion spring (54) is interposed between the body (7) of he seat portion and the seat back (3). The torsion spring (54) is adapted to assume a free state when an upper hook pin (52) is at an .alpha. position. Under these conditions, the seat back (3) is capable of tilting forward to .beta. under its own weight. When the seat back 3 is tilted in the direction of .beta., shock is mitigated by the torsion spring (54). When the seat back (3) is tilted toward .gamma. and .delta., half-latching and play in the back-and-forth direction are prevented. When the infant-restraining protective seat (1) is not in use, the protective seat is folded up to reduce its size and can then be stored. The seat (1) can be carried about and set up on a vehicle seat much more easily.
