  • Patent number: 6105271
    Abstract: An arrangement for accommodating a scale (2) of a length measuring device in a positive-locking engagement has a profile base (1) and lateral profile legs (4, 5) which are connected with the profile base so as to project away from it. A scale (2) is arranged between the profile legs (4; 5). The profile legs (4; 5) are made of elastic material and the profile base (1) is made of a longitudinally stable, bendable material. The profile legs (4; 5) can contain elastic sealing slats.

  • Patent number: 5987768
    Abstract: In an arrangement for fastening a length measurement device at a guide rail for a guide slide which is movable in the longitudinal direction of the guide rail and has a measurement rod and a measuring head which is movable relative to the latter, wherein the measuring head is detachably connected with the guide slide, the measurement rod is coupled directly, or indirectly in a positive engagement via a measurement rod carrier body connected with it, directly to the guide rail (1)so as to be detachable. The measurement rod or the measurement rod carrier body can be inserted by its longitudinal edges into corresponding recesses arranged at the guide rail.

  • Patent number: 5924214
    Abstract: In a length measurement device for measuring the relative position of two objects in which a scale is connected with one object via retaining elements and the ruling of the scale is sensed by a sensing unit formed of a measurement head and a measurement carriage, wherein the sensing unit is coupled to the other object via a coupling point by drivers which are constructed as a deflectable, elastic coupling device. The coupling device is fastened to the measurement carriage at two connection locations, wherein the coupling point is arranged between these connection locations for coupling the sensing unit to the other object.
