Array of coils with at least one linear segment in each coil end between which a lacing wire is engaged

摘要

Spring and coil designs and reflexive systems or innersprings which utilise a plurality of springs or coils (10) are disclosed. Each of the coils (10) that are interconnected in array for use in an innerspring comprises a generally cylindrical body (12) with two or more helical turns (121-126) of wire which form a helical path about a longitudinal axis of the coil (10). There is a step (20) which extends between one of the ends (14) of the coil (10) and the coil body (12). This step (20) does not follow the helical path of the coil body (12). Each of the two ends (14 and 16) of the coil (10) has at least one linear segment. When the plurality of coils (10) are interconnected in array, a lacing wire is included in such a way that it extends between coils (10) and is engaged with linear segments of the coil ends (14 and 16).
