The present invention is directed to support members for assemblies of conductors, conduits, or other means of conveying energy, gases, or liquids. The invention has a series of non-interlocking solids disposed along the length of a flexible base material. The non-interlocking solids have motion-limiting portions that contact similar portions on adjacent solids to restrict the movement of the support member in one direction, while permitting the support member to curve or bend in an opposite direction. The invention is also directed to assemblies incorporating the support members.

When a cable support structure according to the present invention is applied to a slide door in a vehicle, a first support member (20) and a second support member (30) support one end portion and another end portion in a cable guide (1) in a state capable of swinging them in a vertical direction approximately perpendicular to a sliding direction (Q) of a slide door (SD). Accordingly, even in the case where an attitude angle of the slide door (SD) with respect to the vertical direction is changed in correspondence to the slide movement, or a vertical position is changed, it is possible to prevent an unreasonable force from being applied to the cable guide (1) on the basis of the above-described attitude or position change.

Breakage in a coupling portion of a side plate subjected to repeated flexure is prevented by using fatigue resistant resin materials in the side plate. The coupling portion of the side plate due is subjected to repeated flexure. Excellent fatigue resistance is realized. The fatigue resistant resin material is selected from the group of an elastomer- or rubber component- compounded polyamide resin and polybutylene terephthalate resin. The rubber component is selected from the group of ethylene-propylene rubber (EPDM), nitrile rubber (NBR) and butyl rubber (IIR).

The pin and center link of the invention is used in a rivetless chain. It is manufactured to contain a reservoir to receive a lubricant. The reservoir may be in the form of a hole or a groove of various configurations. The lubricant is inserted into the pin or center link to provide lubrication to the center link/pin interface for extending the life of the chain. The size and location of the reservoir are selected to optimize the overall balance between load bearing strength and lubricant surface area at the center link/pin interface. The lubrication system of the present invention will also prevent leakage of lubricant onto the product and provide a clean environment.

A cable management system for managing at least one cable extending through a support arm and through a hub, comprised of a spool disposed in a hub. The spool has an opening extending through a wall of the spool. A cable carrier is disposed within the support arm.

Provided is a cable or the like protection and guide device, which can suppress the sliding contact noise by reliably limiting a linear position and a bending position exhibited during the movement of the cable or the like, and at the same time, which can reduce a setting space by suppressing the impact noise and wear of a connecting pin piece on a connecting pin hole even if the height size of the link body is decreased. A connecting pin piece, convexly provided on a link body, which forms a cable or the like protection and guide device, includes stopper surfaces, which are parallel to the upper edge center portion and the lower edge center portion of the side plates and are oppositely disposed across a bending center point and a pair of front, and rear arc-shaped outer circumferential surfaces, which are oppositely disposed across the bending center point. Further a connecting pin hole, concavely provided in said link body, includes a pair of linear position maintaining surfaces, which are parallel to the upper edge center portion and the lower edge center portion of the side plate, and are oppositely disposed across the bending center point, bending position limiting surfaces, which are oppositely disposed across the bending center point in a plane symmetry, and a pair of arc-shaped inner circumferential surfaces oppositely disposed across said bending center point in a plane symmetry to be brought into sliding contact with said connecting pin pieces.

The plate body has a first side surface adapted to face an abutment plate, a second side surface opposite to the first side surface, and an annular peripheral surface interconnecting outer peripheries of the first and second side surfaces and having first and second ends opposite to each other in a longitudinal direction. The first wing extends integrally from the first end of the peripheral surface in the longitudinal direction, and has a first side surface facing the abutment plate. The distance between the first side surface of the first wing and the abutment plate is smaller than that between the first side surface of the plate body and the abutment plate.

In a deformable structure, connecting parts each of which has a base part are arranged longitudinally so that adjacent connecting parts are connected to each other. Respective first axes of the adjacent connecting parts are inclined to each other in a state that a spacer on one of the two adjacent base parts comes into contact with the other base part. When an external force is exerted on the deformable structure, the spacers restrain the deformable structure from being further curved into a radius of curvature smaller than a predetermined allowable radius of curvature. Most of the external force exerted on the deformable structure is born by the base parts and the spacers so that only a low force acts on the connecting parts. Thus the connecting parts do not break easily so that the deformable structure has a high strength.

According to the invention, at least one of the plates is firstly produced followed by the production of at least one of the cross-connecting elements while simultaneously forming a joint connection between one of the plates and one of the cross-connecting elements.
