The invention relates to a tension spring clamp in which the clip spring (2), which is bent out from a spring blade, is used for bracing an electric conductor against a conductor rail (1).
An extension spring linked between the slider and the shuttle abruptly pulls the shuttle to retract the pull wire after the slider is fully retracted.
First and second preferred embodiments of the invention are adapted for use with extension spring garage doors and torsion spring garage doors, respectively.
An elastic means (17) embodied as a tension spring is inserted into the pressure chamber (7), said elastic means counteracting the hydraulic pressure.
The annular tension spring (23) can carry out a rolling motion around the central axis (24) of the cable.
The jaws (9, 10) are acted upon by a draw spring (22) or spring clip (31), whose direction of force works near the fulcrum of the legs (1, 2) in the open position of the trap.
A reinforcement of the toothed belt acting as a tension string ensures that the necessary belt tension is maintained. .
A tensioning spring in the form of a ring serves as clip element and also serves as the locking element.
A draw spring (18) is arranged between the movable fixing board (3) and the motherboard (1).
The tension-spring elastic potential energy generating device is disposed inside the post (41).
A corresponding arrangement is provided for a piston in a tension gas spring.
A traction spring acts between both intermediate members (14, 16) pressing both intermediate members (14, 16) against the centering ball (58).
According to the invention, the spring (15) is embodied as a draw spring, in particular as a spiral draw spring.
A traction spring (48) permanently stresses on free end (36) of the clutch spring in the direction tightening said spring on the hub (16).
