    专利说明:

    The invention relates to a storage of a rotationally or translationally movable component of a work having a clock on a stationary component of the clock.
    For the storage of rotationally or translationally movable components, it is known to use roller bearings or plain bearings. In particular, when using rolling bearings, the disadvantage that the storage has a relatively high weight and in jerky movements of the movable member, as is the case with digital displays of the clock, clockwork parts heavily stressed and leads to damage.
    The object of the invention is therefore to provide a storage of the type mentioned, which has a low weight with low space requirement and in which the installation is simple and the adjustment effort is low.
    This object is achieved according to the invention in a first solution, characterized in that the movable member has one or more along its path extending edges constant cross-section in which a plurality of spaced apart bearing rollers with radially encircling grooves at their radially encircling circumference leader with axes perpendicular to the path of movement of the movable member, about which the bearing rollers are freely rotatably mounted, with eccentric bearing lugs adjoining axially on the axles, which are frictionally adjustably mounted with frictional resistance in corresponding bearing recesses of the stationary component of the watch.
    In a second solution, the object is achieved in that the fixed component has one or more along the path of movement of the movable member extending edges constant cross-section, in which a plurality of mutually spaced bearing rollers with radially encircling grooves at their radially encircling Surround intervene leader, with the path of movement of the movable member perpendicular extending axes about which the bearing rollers are freely rotatably mounted, with axially adjacent to the axes eccentric bearing lugs which are rotatably mounted under frictional resistance in corresponding bearing recesses of the movable member of the clock.
    By these solutions storage with low weight and low space requirement is achieved. In addition, the bearing friction is low, so that the braking torque generated by the bearing friction is low.
    During assembly, the bearing lugs are first rotated so that the axes and with them the bearing rollers are in a position spaced from the end position. Now, the component, in which the grooves of the bearing rollers are to engage, without obstruction by the bearing rollers are used so that it is in the same plane as the bearing rollers. By rotating the bearing lugs, the bearing rollers are now moved toward the component to be supported until the bearing rollers are in an optimum position to the component to be supported and engage the grooves of the bearing rollers in the edge or the edges of this component.
    The inventive storage require only a small space and are resistant to wear.
    Through the grooves of the bearing rollers is a low-heel leadership of the movable component.
    Has the cross section of the grooves of the bearing rollers on a V-shape, a particularly low-height play leadership of the movable component is achieved.
    For a rotary bearing, the fixed component may have a circular, radially encircling outer edge, in which engage the bearing rollers with their grooves.
    The translationally movable component may be a longitudinally extending lever, engage in the two longitudinal edges of the bearing rollers with their grooves and translationally store.
    A further improvement of the low-height play leadership of the movable member is achieved in that the along its movement path extending edge or the edges have a V-like cross-section.
    The movable component may have two mutually plane-parallel surfaces.
    If the stationary component is a circuit board of the movement of the clock and extends parallel at a distance from the plane-parallel surfaces of the movable component, so there is a dual function of the board and it is a space-saving construction achieved.
    For rotatable adjustment of the bearing lugs connected to the axes, the bearing lugs can have a rotary drive contour into which a tool for rotating the bearing lugs can be engaged.
    In a simple way, the rotary driving contour is a transverse to the axis extending slot in the free end face of the bearing lug, in which a screwdriver is inserted.
    The rotatably movable member may be a toothed ring which is rotatably supported by means of the bearing rollers on the circular peripheral edge of the fixed component, wherein concentrically with the toothed ring a numeric and / or dial a digital display of the clock can be connected.
    In a simple manner and easy to install while the toothed ring can be connected by means of a screw connection with the number and / or dial.
    A particularly small space is required when the toothed ring and the number and / or dial are arranged at a distance parallel to each other and the bearing rollers and the stationary component in the distance between the toothed ring and numeric and / or dial.
    In this case, the number and / or dial can be an hour disc of the digital display of the clock.
    Embodiments of the invention are illustrated in the drawings and will be described in more detail below. Show it<Tb> FIG. 1 <SEP> a plan view of a unit of a clock from toothed ring, hour disc and their rotational bearing on the toothed ring<Tb> FIG. 2 <SEP> a first section of the unit of FIG. 1 in cross section<Tb> FIG. 3 <SEP> a second section of the unit according to Fig. 1 in cross section<Tb> FIG. 4 <SEP> a third section of the unit of FIG. 1 in cross section<Tb> FIG. 5 <SEP> a plan view of a translationally mounted lever of a clock.
    The unit shown in FIGS. 1 to 4 has a toothed ring 1 with an internal toothing 2, which has six radially projecting flange sections 3 distributed uniformly on its outer circumference. In each flange portion 3, a circumferentially extending slot 4 is formed.
    The flange portions 3 have a greater thickness than the toothed ring 1, so that they project axially from the toothed ring 1 to one side.
    On the protruding end face of the flange 3 is an annular hour disc 5, the outer diameter is greater than the outer diameter of the flange 3 and the inner diameter is smaller than the diameter of the internal teeth 2 of the toothed ring 1. By the protrusion of the flange 3, an annular gap 12 is formed between the toothed ring 1 and the hourly dial 5.
    With the central regions of the slots 4 overlapping and having a diameter corresponding to the width of the slots 4 are formed in the hourglass 5 step-like through holes 6, the large step are located on the flange portions 3 side facing away from the hour disc 5.
    In the through holes 6 sockets 7 are inserted with an internal thread, which protrude into the slots 4 and at their ends facing away from the flange 3 radially outwardly projecting flanges 8, which are inserted into the large stages of the through holes 6.
    From the hour disc 5 side facing away screws 9 are guided through the through holes 6 and screwed into the internal thread of the sockets 7 until the screw heads 10 of the screws firmly against the hourglass 5 side facing away from the flange 3, so that the toothed ring 1 and hour disc 5 are firmly connected.
    Coaxially with the toothed ring 1, an hourly board 11 of the movement of the clock is arranged stationary, which projects through the interior of the hourglass 5 and at its free end has a radially projecting annular flange 13, which projects into the annular gap 12. The radially encircling edge 14 of the annular flange 13 has a V-like cross-section.
    Arranged uniformly on a concentric pitch circle of the toothed ring 1 are three bearing recesses 15 designed as bores, in which bearing projections 16 are inserted, which are rotatably adjustable by overcoming a frictional resistance in the bearing recesses 15.
    At the bearing lugs 16 axle bolts 18 are arranged, the axes 19 extend eccentrically to the longitudinal axes 17 of the bearing lugs 16 and project into the annular gap 12.
    On the axle 18 bearing rollers 20 are freely rotatably mounted, which have radially encircling grooves 21 on the outer circumference, whose cross-section has a V-shape corresponding to the V-like cross-section of the annular flange 13.
    To rotate the bearing lugs 16, these have on their free end face a cloverleaf-like recess 22 into which a corresponding tool can be inserted. By the tool, not shown, the bearing lugs 16 can be rotated about its longitudinal axis 17.
    Due to the eccentricity of the axes 19 of the axle 18 to the longitudinal axes 17 of the bearing lugs 16, the bearing rollers 20 between one of the peripheral edge 14 of the annular flange 13 spaced position (Fig. 3) and one with its circumferential grooves 21, the peripheral edge 14 of the annular flange 13 receiving position (Fig. 4) adjustable, in which the unit of hour disc 5 and the toothed ring 1 is rotatably mounted on the annular flange 13.
    When assembling the hour board 11 is first placed with its annular flange 13 on the hour wheel 5, before the toothed ring 1 is placed with the flange 3 on the hour wheel 5 and screwed with this. The bearing rollers 20 must be located in the spaced from the peripheral edge 14 of the annular flange 13 position.
    After screwing of the toothed ring 1 and hour disc 5 all three bearing lugs 16 must be rotated in succession in uniform steps and with them the bearing rollers 20 are moved toward the annular flange 13 out until only a minimal clearance between the grooves 21 and Edge 14 is present. Now the unit of hour disc 5 and toothed ring 1 is rotatably mounted on the annular flange 13.
    In the embodiment of Fig. 5, an arcuate lever 23 is mounted translationally movable along an arcuate path 24.
    The edges 14 at the radially outer end portions 25 and 26 and at the radially inner central region 27 corresponding to the edge 14 in Figs. 1 to 4 are formed.
    In the end regions 25 and 26 and the middle region 27 engage the bearing rollers 20 corresponding bearing rollers 20 in the edges 14 and store the lever 23 translationally movable.
    The bearing rollers 20 are rotatably mounted according to the embodiment of FIGS. 1 to 4 on axle, which are provided with bearing lugs. The axes of the axle bolts extend eccentrically to the longitudinal axes of the bearing lugs.
    The bearing lugs are rotatably mounted in bearing recesses in a stationary work plate 28 such that they are rotatably adjustable by overcoming a frictional resistance in the bearing recesses 15.
    During assembly, according to the embodiment of FIGS. 1 to 4 by turning the bearing lugs initially set the bearing rollers 20 at a distance from the edges 14 to hang the lever 23 on the work plate 28. Thereafter, the bearing lugs are rotated so that the bearing rollers 20 are moved to the lever 23 until only a minimal clearance between the grooves of the bearing rollers and the edges 14 is present. Now, the lever 23 is translationally movable and mounted with play on the work plate 28.
