  • Patent number: 5865282
    Abstract: In a system comprising at least two conductor rails, in particular composite sections each featuring a rail-shaped load-bearing section and at least one strip-shaped section of another metal of greater wear resistance joined to the matrix of the load-bearing section, the ends of pairs of neighbouring rails are connected electrically by at least one conductor of variable length. The ends of the conductor rails are bent out of the central axis (M) of the conductor rail and led parallel to and a distance (n) displaced from that axis, such that the strip-shaped section of one conductor rail end is approximately aligned with the strip-shaped section of the other conductor rail away from the rail end; the conductor rail ends are joined in such a manner that they can move with respect to each other along the axial direction.

  • Patent number: 4889281
    Abstract: The present invention relates to an improved sliding rail construction for rowing exercising machine, in which, the sliding rail for rowing exercising machine is formed by combining an upper sliding stripe made of aluminum alloy and a rail base made of ferrous metal together, and which permits the whole sliding rail construction to be more easily connected to the base rods while providing very good sliding ability for the seat pad placed thereon. Thus the present invention is capable of reducing the production cost, simplifying the manufacturing process and improving the quality of the rowing exercising machine.

  • Patent number: 4284181
    Abstract: A rigid trolley rail having a continuous unified structural body which is formed by continuously laying a plurality of short trolley rail bodies made of aluminum along the track of a travelling body and by mechanically connecting or welding confronting ends of adjacent trolley rail bodies to each other. Each of the plurality of aluminum trolley rail bodies consists of a base part attached to fixed support parts, a protruding middle part formed to protrude from the middle portion of the upper or lower face of the base part approximately into a T-shape; and a pair of protruding clamping strips positioned with the protruding middle part interposed between them. A long single sheet of stainless steel is bent to cover the protruding middle parts of the aligned rail bodies to form the continuous unified structural body and the ends of the two bent sides thereof are fixed in a gripping manner by bending the pair of protruding clamping strips inwardly to clamp the bent sides against the base part.
