Abstract
A device for connecting a spring to a band-like or cable-like transmission apparatus. The device being easy to assemble and in which the risk of fracture of the device is greatly reduced. The device provides a connecting part to be fitted on the transmission apparatus and a hook-in part to be connected onto the spring. The connecting part then being connected to the hook-in part to connect the transmission apparatus to the spring.
Claims9
A device for interconnecting a spring and a belt-shaped or rope-shaped transmission element, which comprises:
- a connecting part being substantially cuboid and having a longitudinal axis, a front portion, a middle portion and a rear portion;
- said connecting part having two recesses formed therein resulting in a substantially T-shaped cross-section at said front portion, a substantially H-shaped cross section at said middle portion, and a substantially rectangular cross section at said rear portion, the cross sections taken perpendicular to the longitudinal axis;
- and
- a hook-in part having two substantially L-shaped hooks, said hooks having ends facing each other, and said ends of said hooks formed to be hooked in said recesses.
A device for interconnecting a spring and a belt-shaped or rope-shaped transmission element, which comprises:
- a connecting part to be fixedly connected on the transmission element;
- a hook-in part to be mounted in and held by the spring, said connecting part being hooked into said hook-in part for connecting the spring to the transmission element;
- said hook-in part having a receiving region for said connecting part, said receiving region being formed with a centrally slotted eyelet and two hooks forming forward and lateral boundaries thereof, said hooks having ends projecting towards one another at a spacing;
- said connecting part being a flat plate having a longitudinal axis and being formed with two laterally spaced-apart regions at a given spacing, each of said spaced-apart regions having a recessed step formed therein, such that a cross-section taken perpendicularly to the longitudinal axis of said flat plate is substantially T-shaped, said recessed step being at least as deep as a protruding length of said hook-in part, and the given spacing at most equals the spacing between said ends of said hooks of said hook-in part;
- and
- a plate having an inner side covering a region of said connecting part at ends of said recessed step and disposed opposite said recessed step, at least a spacing equal to the thickness of said hook-in part remaining between said inner side of said plate and a surface of said recessed step.
