Abstract
The present invention relates to a cursor chain including a plurality of cursors joined together by divisible bridging pieces (30), and including a linking device at each end in order to interconnect the ends of two cursor chains so as to form a longer chain overall, characterised in that it includes attachment means which are not of cylindrical revolution.
Claims12
Cursor chain including a plurality of cursors joined together by divisible bridging pieces (30), and including a linking device at each end to interconnect the ends of two cursor chains in order to form a longer chain overall, characterised in that the linking devices include attachment means which are not of cylindrical revolution.
The chain according to the preceding claim, characterised in that the attachment means prevent any relative movement in rotation, or in longitudinal translation and/or transverse translation of the cursor chains when they are interconnected.
The chain according to any of the preceding claims, characterised in that the total thickness of the attachment means, once assembled, is of the order of that of the divisible bridging pieces (30) within a chain.
The chain according to any of the preceding claims, characterised in that the attachment means are divisible.
The chain according to any of the preceding claims, characterised in that it includes two tabs (1, 2) of complementary shape respectively at its ends.
The chain according one of the preceding claims, characterised in that the attachment means (3 to 10) are composed of at least one attachment element, with the attachment element including a projection (3, 6;
- 8, 10) and a cavity (4, 5, 7, 9).
The chain according to the preceding claim, characterised in that a projection (3, 6;
- 8, 10) is formed at one of the ends (1, 2), and that it is complementary to a cavity (4, 5, 7, 9), formed at the other end (1, 2).
The chain according to any of the preceding claims, characterised in that it is created by injection moulding in a plastic material, in particular of the polyoxymethylene or polyolefins type, such as high and low density polyethylene or polypropylene.
