    Abstract: To provide a backlash-free rack simple in structure and small in size, still assuring that no backlash is caused in reciprocating a movable part in an electronic device toy, or watch et al, the rack structure comprises first and second toothed bars both integrally connected to each other by an intermediate joint made of a soft resin material to provide a linear toothed bar object. The linear toothed bar object is so folded about the intermediate joint that the first and second toothed bars are somewhat staggered and laid on each other with their teeth out of phase, thereby preventing the backlash which otherwise, would be caused between the teeth of the rack and those of the pinion.

    Abstract: The invention describes a focusing drive for optical instruments that has, in addition to a pinion (1) and toothed rack arrangement (1, 2), slide rods (4) as guidance means for continuously changing the relative position of optical assemblies with respect to one another. The toothed rack (2) has a plurality of support elements (3) that are arranged—for example in angled fashion—on either side of its longitudinal extent. The support elements (3) are designed so that they have a shallow S-shape in cross section. In addition, they are dimensioned in such a way that they touch the contact surface of the one housing module (5) only with their planar end regions (3a). The result is a resilient or flexing motion upon actuation of the pinion (1), thus achieving smooth and zero-backlash adjustment.

    Abstract: An apparatus (10) for use in turning steerable vehicle wheels includes a rack gear (14) and a sector gear (16) which are disposed in meshing engagement. A housing (30) encloses the rack and sector gears (14 and 16). A sector shaft (22) has an inner end portion (34) connected with the sector gear (16) and an outer end portion (36) disposed outside of the housing (30). A lash adjustment assembly (56) is operable to move the sector gear (16) and shaft (22) relative to the housing (30) to reduce clearance between teeth (18 and 20) on the rack and sector gears. The lash adjustment assembly (56) is manually actuatable at the outer end of the sector shaft (22). The lash adjustment assembly (56) includes an elongated member (60) which extends through the sector shaft (22) and the sector gear (16) into engagement with the housing (30).

    Abstract: In a condition responsive device, such as a load responsive weighing scale, a rotatably mounted pinion is engaged with a pivotably mounted balanced rack which is movable in response to change in the condition. A spring is provided for urging the rack into engagement with the pinion and for maintaining the meshing force between the rack and the pinion substantially constant during all positions of the rack.
