摘要:
A triple-lock handcuff (20) of the type having a blade (40) pivotally joined to spaced-apart cheek plates (28, 30) for movement through a locking channel (54) includes several improvements. The lock assembly includes first and second pawl members (84, 86) resiliently urged toward the channel (54) independently of one another by separate springs (102, 104). A key operated extractor block (124) carries a yoke (126) for moving both pawl members (84, 86) simultaneously away from the channel (54) to open the handcuff. The first and second pawl members (84, 86) are spaced-apart within the locking channel (54). An elongate resilient cushion (150) is arranged along the inner edge (46) of the blade (40) so as to assume a first unloaded profile (150A) capable of passing between the cheek plates (28, 30) and, alternately, a second profile (150B) when bearing upon a limb, incapable of passing between the cheek plates (28, 30). A sleeve (152) detachably fastens the cushion (150) to the blade's inner edge (46) while leaving the blade's outer edge (48) free of overlay. When the cushion (150) is loaded, the sleeve (152) locks the cushion (150) on the edge (46) of the blade (40) by urging a pair of opposed feet (160A, B) into grooves (174) formed in the sides (50) of the blade (40).
摘要:
An "arrest" handcuff has the usual ratchet and pawl mechanism for closing the wrist aperture. In order to deadlock the pawl (10) a runner (16) is shifted by means of a manual push-button (22) extending from the back face of the runner so that a stump (19) on the runner then overlies the nose (23) of the pawl. To release the deadlocking and pivot the pawl clear of the ratchet the runner (16) must be shifted to the left, which movement is normally blocked by a lever pack (25) operating on the runner stump (21). A correct key, however, can lift the levers and turn the runner back. If the option to deadlock the pawl is not taken up in any particular arrest situation the pawl still remains engaged with the ratchet under its spring bias (13) and the correct key is still needed to perform a leftward movement of the runner to lift the pawl from the ratchet.
摘要:
Menotte composée d'un premier demi-bracelet (21) et d'un second demi-bracelet (11), et au moins un corps de menotte (1) comprenant des moyens de verrouillage (22, 41, 5, 7) et déverrouillage (4, 5, 9) de la menotte, le second demi-bracelet (11) étant solidaire ou non du corps de menotte. Selon une caractéristique principale, le premier demi-bracelet est monté pivotant autour d'un axe (100) situé dans le corps de menotte. La menotte comprend des moyens de commande (3, 6, 200, 24) permettant de mettre le premier demi-bracelet en mouvement autour de son axe de façon à permettre une préhension frontale du membre à entraver
摘要:
The invention relates to a handcuff consisting of a first half-bracelet (21) and a second half-bracelet (11), and at least one handcuff body (1) including a means for locking (22, 41, 5, 7) and unlocking (4, 5, 9) the handcuff, the first half-bracelet being pivotably mounted about a pin (100) located in the handcuff body and the second half-bracelet optionally being rigidly connected to the handcuff body. The handcuff also includes a means for locking the handcuff in an open position comprising a locking detent (6) pivotably mounted about a pin (103) attached to the handcuff body and the first half-bracelet comprises a notch (23) in which the locking detent is inserted by countering a return spring (203), which makes it possible to lock the first half-bracelet and to keep the handcuff in the open position in order to prevent the untimely closing thereof, as well as enabling the limb to be shackled to be gripped from the front.
摘要:
Disposable handcuffs comprising a flat strap (1) of flexible material forming adjustable loops and a box (2) for fixing the central section (14) of the flat strap and provided with passages (21, 22) for receiving the flat strap (1), each of the passages (21, 22) having a strap supporting wall and an opposite partially offset wall (23, 24) forming a cavity between said walls closed on the loop adjacent side of the box (2) and opened on the opposite site of the box (2). A rotational body (4) is located within each of the cavities for contact of the rotational surface thereof with the offset wall (23. 24) on one side and with the flat strap (1) on the other side, a boss including a sharp end extending from the rotational surface to engage the flat strap (1) in the area of the cavity adjacent to the opposite side of the box (2).
摘要:
A clamp, clamping means incorporating the clamp, and a method of clamping are disclosed. The clamp includes means for clamping a securing tie therein, together with means for attachment to a surface, and, in combination with a securing tie, provides a clamping means suitable for clamping objects to a fixed point.
