    description
    The invention relates to a parking brake device for a trailer, in particular a car trailer.
    For smaller trailers without overrun brakes wheel chocks are used as parking brake devices. However, these have the disadvantage that the trailer can move unintentionally after uncoupling until wheel chocks are placed on both sides of the trailer. This can lead to accidents and/or injuries, especially on sloping terrain.
    For larger trailers with overrun brakes, a parking brake is provided in part as an additional function. Components of the overrun brake are used here. Internal brake shoes are used for braking.
    It is therefore an object of the invention to provide a parking brake device and a trailer without overrun function, which / r in a simple and safe manner prevents a trailer from rolling away when parked.
    [0005] This object is achieved by the objects and the use of the independent claims.
    According to the invention, the parking brake device is suitable for a trailer, in particular a car trailer, without an overrun function.
    Such trailers without casserole function have not yet had a locking device that blocks the wheels when parking or parking.
    Trailers without a casserole function preferably have a maximum total weight of 750 kg. The payload can in particular be between 500 kg and 650 kg.
    The inner length can in particular be between 1 m and 3 m, preferably between 1.5 m and 2.5 m, for example 1.65 m, 2.05 m or 2.51 m.
    The inner width can in particular be between 0.5 m and 2 m, preferably between 1 m and 1.5 m, for example at 1.095 m, 1.1 m or 1.31 m.
    The loading height can in particular be between 0.1 m and 1 m, preferably between 0.4 m and 0.6 m, for example 0.495 m, 0.5 m, 0.51 m or 0.53 m.
    For example, the trailer may have two wheels mounted on a common axle. Alternatively, four, six or more wheels are conceivable, with two wheels being arranged on a common axle. Trailers with one axle or with two, three or more axles are conceivable.
    For example, only the front wheels, only the rear wheels or all wheels can be blocked. In particular, a parking brake device can be provided for the front and/or rear axle.
    In particular, conventional single-axle trailers and/or two-axle trailers can also be retrofitted with a parking brake device according to the invention.
    The parking brake device secures the trailer when parking or parking. If the trailer is connected to a vehicle, e.g. a car, the parking brake device is released and thus does not impede either the vehicle or the trailer while driving.
    The parking brake device is not used as an overrun brake, since an overrun brake is not necessary for these trailers due to their low weight.
    The parking brake device has two outer brake shoes assigned to different wheels of the trailer in the installed state.
    [0018] In particular, the two wheels are attached to a common axle of the trailer
    arranges.
    The parking brake device thus acts simultaneously on two wheels arranged on different sides of the trailer. This prevents the trailer from turning unintentionally.
    The outer brake shoes act on the wheels from the outside. This simplifies subsequent assembly compared to internal shoe brakes.
    The outer brake shoes can in particular have a friction-enhanced material, e.g. rubber material, and/or a friction-enhanced structure.
    A manually operable triggering device is provided. This can in particular be a handbrake lever. The triggering device can preferably be adjusted between a release position and a braking position. For example, the triggering device can lock in the respective positions in order to prevent unintentional adjustment.
    In particular, a safety device, e.g. a lock, can be provided in order to secure the triggering device in the release position and/or the braking position. The safety device can in particular serve as protection against theft and/or prevent unintentional triggering.
    The parking brake device comprises an adjusting device connected to the triggering device and a distributor device connected to the adjusting device. The adjusting means is designed in particular to pass on a force introduced at the triggering device to the distributor device.
    The parking brake device has an actuating device connected to the outer brake shoes.
    The distributor device is designed to adjust the actuating device between a release position and a braking position.
    In the release position the outer brake shoes are spaced from the tires of the wheels, while in the braking position the outer brake shoes are in contact with and e.g.
    [0028] Further developments of the invention can also be found in the dependent claims, the description and the accompanying drawings.
    According to one embodiment, the adjusting means comprises a pulling and/or pushing means or is designed as such. The pulling and/or pushing means can in particular be a rod, a flat bar, a cable and/or a Bowden cable. In particular, the rod can have a round or angular cross-section. In particular, the rod can be designed as a tube.
    In particular, a resetting device, e.g. a tension spring, can be provided, which is designed to reset the adjusting means. A restoring device is particularly advantageous in the case of a non-rigid means of traction and/or pressure, for example in the case of a cable and/or a Bowden cable.
    Preferably, the adjusting means comprises or is formed from a metal material, e.g., iron, steel and/or aluminium, a plastic and/or textile material.
    The actuating device can be designed in particular as a rod and/or flat bar. In particular, the rod can have a round or angular cross-section. In particular, the rod can be in the form of a tube, round iron or multi-edged iron.
    Preferably, the actuating device comprises or is formed from a plastics material and/or a metal material, for example iron, steel and/or aluminium.
    [0034] According to a further embodiment, the outer brake shoes are on a common
    men actuating unit of the actuating device arranged.
    In this case, the outer brake shoes are preferably rigidly connected to one another. The one-piece actuating device makes production cost-effective. Possible wear and tear is also minimized, as a result of which maintenance and/or repair costs are kept low.
    According to an alternative embodiment, the outer brake shoes are arranged on different actuating units of the actuating device, with the actuating units being designed to be movable relative to one another.
    The actuating device is consequently not designed in one piece. Each outer brake shoe is arranged on a different operating unit.
    The outer brake shoes can thus be moved independently of one another to a certain extent. For example, deviations in tire pressure or differently worn tire profiles can be compensated. Due to the fact that the outer brake shoes are moved individually via the respective actuating units, the same braking force can be provided on both sides even if the circumstances of the wheels are different.
    According to a further embodiment, the actuation units are connected to one another by means of a link guide. The acknowledgment units are to some extent forced coupled.
    Preferably, at least one actuation unit comprises a groove, e.g. a slot, and the other actuation unit a sliding block. Alternatively, both actuation units can each have a groove, e.g. a slot. The grooves can be attached to one another using a sliding block, e.g. a screw or a bolt.
    In order to prevent the actuating units from breaking out upwards or downwards, one or more hold-down devices, e.g. a metal sheet, can be provided in particular.
    According to a further embodiment, the distributor device is connected to both actuating units.
    [0043] A force introduced at the triggering device is consequently forwarded via the distributor device to both actuating units, in particular in equal parts.
    For example, the distributor device can be connected to the two actuating units by means of a bolt, preferably with a cotter pin.
    According to a further embodiment, a mounting device for mounting the actuating device on the trailer, in particular on an axle of the trailer, is provided.
    The actuating device is preferably rotatably or pivotably mounted on the bearing device. The storage device can in particular have several, e.g. two, bearings.
    According to a further embodiment, a spring device is provided for the triggering device. In particular, a mechanical spring and/or gas pressure spring or gas pressure damper can be provided. The trigger device is thus supported, for example. The exertion of force by a user can be reduced in particular as a result. The braking value can be improved by the spring device, for example.
    The spring device can also ensure that the triggering device latches in the release position and/or the braking position.
    The invention also relates to the use of a parking brake device according to the invention for a trailer, in particular a car trailer, without an overrun function.
    The parking brake device according to the invention can already be installed at the factory in new trailers. It is also possible to retrofit existing trailers.
    Finally, the invention relates to a trailer, in particular a car trailer, without
    Overrun function with a parking brake device according to the invention.
    All of the aspects, embodiments and features of the invention described here can be combined with one another, in particular also detached from the specific embodiment in the context of which they are mentioned. In particular, all subject matter of the dependent claims can be combined with each other and with each subject matter of the independent claims.
    The invention is described below by way of example with reference to the drawings. Show it:
    Figures 1 to 4 are bottom views of different embodiments of a trailer according to the invention, and
    5 shows a side view of an embodiment of an actuating device of a parking brake device according to the invention.
    First, it should be noted that the illustrated embodiments are purely exemplary in nature. Individual features can be implemented not only in the combination shown, but also individually or in other technically sensible combinations. For example, the features of one embodiment can be arbitrarily combined with features of another embodiment.
    If a figure contains a reference number that is not explained in the directly associated descriptive text, reference is made to the corresponding preceding or following statements in the description of the figures. The same reference numbers are used for the same or comparable components in the figures and these are not explained again.
    1 shows a trailer without an overrun function, ie without an overrun brake, with two wheels 10 which are arranged on different sides of a common axis 12.
    A parking brake device has two outer brake shoes 14 assigned to the two wheels 10 of the trailer.
    The outer brake shoes 14 are arranged on two different actuating units 16 of an actuating device 18 .
    The actuating units 16 can be moved relative to one another and are connected to one another via a link guide 20 .
    In order to prevent a breaking out upwards or downwards, one or more hold-down device/s 22 can be provided, which is partially shown in dashed lines. The hold-down device 22 can be designed in particular as a sheet metal. This restricts the freedom of movement of the actuating units 16 in the vertical direction, ie in particular upwards or downwards.
    A distributor device 24 is provided on the actuating units 16 of the actuating device 18, which displaces the actuating device 18 between a release position and a braking position.
    For this purpose, the distributor device 24 can in particular have two strands which are each connected to one of the actuating units 16 .
    The distributor device 24 is connected to an adjusting means 26 . The adjusting means 26 is designed, for example, as a rod.
    If a force is exerted on the distributor device 24 via the adjusting means 26, the two actuating units 16 pivot relative to one another.
    For this purpose, the actuating units 16 are mounted pivotably on bearing devices 28 .
    The embodiment shown in FIG. 2 essentially corresponds to the embodiment
    shape according to FIG. 1. The adjusting means 26 is in this case, however, designed as a cable.
    In FIGS. 3 and 4 the actuating device 18 has only one actuating unit 16 which is connected to the distributor device 24 .
    If a force is exerted on the distributor device 24 via the adjusting means 26, the actuating unit 16 rotates, as a result of which it is adjusted between the release position and the braking position. The outer brake shoes 14 are pressed onto the wheels 10 by turning the actuating unit 16 so that the trailer is braked when stationary.
    [0072] The parking brake device is blocked or secured in particular in the braking position by the twisting beyond a tipping point.
    For this purpose, the actuating unit 16 is rotatably mounted on bearing devices 28 .
    In Fig. 5, a parking brake device with a manually operated release device 30 is shown.
    The triggering device 30 includes a handbrake lever 32, which can optionally be connected to a spring device 34 designed as a mechanical spring.
    Instead of the mechanical spring 34, a gas pressure spring 36 can be provided.
    The triggering device 30 is connected to an adjusting means 26 designed as a rod or cable. Alternatively, the adjusting means can be designed as a Bowden cable 38 .
    A force can be transmitted from the triggering device 30 to the distributor device 24 and from there via the actuating device 18 to the outer brake shoes 14 via the adjusting means 26 . The outer brake shoes 14 act on the wheels 10 from the outside and block them.
    In particular, the parking brake device is actuated before uncoupling from the vehicle.
    This prevents the trailer from rolling away in the parked state in a simple and harmless manner.
