Problems solved by technology

[0003]The known part is not entirely satisfactory because the position of the shortening member and retainer pin results in a relatively large minimum value at which the chain can be shortened
The reason lies in the fact that due to the chain path created by the shortening member and the position of the retainer pin, between the end link of the chain and the chain link closest to said end link and able to hang into the shortening member Larger number of chain links required to form a chain loop

Embodiment Construction

[0019] The part shown in Figures 1 to 4 and formed in the form of a shortened hook has a base body 1 whose upper end is formed as a connector bow 2 with a socket 4 bridged by a retainer pin 3 and used for The connector body 6 is provided with a flat part 5, while the lower end of the part forms a shortening member 7 comprising a hook. One end of the retainer pin is held in the blind hole 8 , while its other end is located in a through hole 9 aligned with the blind hole 8 . The spring pin 10 fixes the retainer pin 3 in the hole 8, 9 accommodating the retainer pin. The end links 11 of a chain 12 are connected to the retainer pins 3, the chain 12 being only shown as a shorter part in the figure and being formed by a series of circular steel chains.

[0020] In order to shorten the chain 12 by the minimum amount possible, it is necessary to form a chain loop consisting of a total of 7 links as shown in FIG. 3 . In practice, this corresponds to shortening the chain 12 by an amoun...

Abstract

The invention relates to a component for shortening a chain (12), provided with a connector hook (2) which may be hung in a connector body (6) and a shortening body (7), with a security bolt for securing the position of the connector hook (2) in the connector body (6) which is also embodied as the retainer pin (3) for the end link (11) of the chain (12) for shortening.

Description

technical field [0001] The invention relates to a part for shortening a chain formed, in particular, of circular steel links, said part being provided with a connector bow which can be suspended into a connector body which Preferably a flat part is provided, the connector bow has an insertion opening which can be closed by a safety bolt, said part has a shortening member on the end below the connector bow for shortening the chain, by holding A retainer pin, the end link of the chain is captured and connected to the part. Background technique [0002] A component of the above-mentioned type is known from Figures 5 and 6 of WO 97 / 23405. In a known design, the safety bolt is arranged in the region of the insertion opening of the connector bow in such a way that the safety bolt can move against the action of a spring for the holder of the end link of the chain to be shortened The pin, together with the shortening member, is located at the lower end of the part at a distance fr...
