Definitions
- the present invention relates to a device for securing vehicles against rolling, designed in such a way that two wedges are connected to one another for mutual support by means of a resilient thrust piece. Specifically, it relates to a device for securing vehicles against rolling, comprising two wheel chocks which are connected to one another by means of a resilient sliding and sliding piece, the wheel chocks being arranged either pointing towards one another or in opposite directions.
- Utility model G 83 18 481. A3 takes up this twist in its execution.
- a system which rotatably takes the wedges on a sliding piece with normal to the sliding direction of the spaced elements. For assembly, it is necessary to let the two wedges slide into one another behind the wheel with the sliding piece element attached to them in a captive manner. Subsequently, a toggle lever clamping element is attached to the wedges on the side opposite the sliding piece (in front of the wheel) and tensioned by means of a spring balancer.
- Both inventions mentioned above consist of several individual parts and are sometimes complex to assemble. Since the wedges are not directly connected to the sliding or spring elements, dangerous situations can arise when they are set or removed.
- the object of the invention is therefore to provide a compact embodiment which enables easy and safe handling.
- this object is achieved in that the wheel chocks are rotatably connected to the sliding and sliding piece about a respective axis of rotation.
- Rotatable here means that the wheel chocks can be pivoted at least a few degrees in relation to the sliding and sliding piece. It can be provided that this is possible by, for example, only 3 ° or 5 °, preferably at least 15 °. This ensures that the wheel chocks can be set up in an optimal angular position for application to a vehicle.
- the wheel chocks are preferably rotatable independently of one another.
- a connection around the axis of rotation means that a connection between the washer wedge and the sliding and sliding piece is provided in the area of the axis of rotation and essentially along the axis of rotation.
- This connection is preferably established via a shaft, whereby the rotatability can easily be achieved.
- the axis of rotation of the wheel chock is preferably parallel to a receiving surface of the wheel chock for resting on a wheel of a vehicle and especially preferably along an edge of the receiving surface.
- the sliding and sliding piece is preferably rigid along its main extent and is designed, for example, as a rod-shaped element.
- the present invention differs from the prior art in such a way that the wedges rotatably connected to the sliding piece are designed as one unit with this sliding piece.
- the application of the anti-roll protection is thus both much easier and safer, since the operator does not have to reach behind or under the wheel at any time to set the anti-roll protection.
- the fixed connection of the sliding element and wedge provides support when removing a wedge under load. Since the wedges are only supported around one pivot point, nestling against the wheel on uneven ground is more consistent than as described in utility model G 83 18481. A3, since here each wedge is assigned to one of the elements between the independently operating sliding element and tensioning element Pivot point is clamped. The combination of the folding axis of the hinged wedges and the axis of rotation of the wedge on the spring element enables space-saving stowage when the anti-roll device is not used.
- At least one wheel chock is secured against axial displacement by means of at least one stop on the respective axis of rotation. This secures the wheel wedge and requires a design with as few individual parts as possible.
- At least one wheel chock is designed as a hinged wedge, the respective axis of rotation for the rotatable mounting of the wheel chock at the same time representing the hinged axis for the wheel chock.
- a hinged wedge is understood to be a wedge that has a receiving element for receiving or to put on a wheel, at least one folding element for fixing the receiving element in a pivoted position about the folding axis and preferably a supporting element for supporting the ground, whereby the position of the folding element to the receiving element of the angle is adjustable in at least two Stel lungs.
- pivot pins running in the axes of rotation are provided, which rotatably connect the respective wheel wedge to the sliding and sliding piece.
- pivot pins are guided through the sleeves of the sliding and sliding piece and have handles for operating the device on the side of the sliding and sliding piece opposite the hinged wedges. Rotation around the axis of rotation can thus be carried out using the handles.
- the sliding and sliding piece can be telescopically extended and is preferably pretensioned in the direction of a contracted position.
- the sliding and sliding piece has at least two telescopic parts which are at least partially arranged one inside the other.
- the sliding and sliding piece for suspension has at least one spring element for biasing the sliding and sliding piece into a contracted position.
- the spring element is at least partially arranged in the interior of the sliding and sliding piece and that the spring element is preferably connected to at least one pivot pin, particularly preferably is suspended from at least one pivot pin.
- a device for securing vehicles against rolling can also be advantageous, which has two wheel chocks which are connected to one another by means of a resilient sliding and sliding piece, the wedges being arranged either towards one another or pointing in opposite directions, characterized in that the chocks on a respective normal to the sliding and sliding piece spaced mandrel with the sliding and sliding piece connected to each other and secured by means of a stop on the respective mandrel against axial displacement.
- pivot pins are arranged along the axes of rotation and the wheel chocks are each rotatably connected to the sliding and sliding piece via the pivot pin.
- Figure 1 an embodiment of the invention with two hinged wedges, directed towards each other, connected by means of sliding and sliding pieces, in a plan view;
- FIG. 2 a section along the line A-A of FIG. 1;
- FIG. 3 a section along the line B-B in FIG. 1;
- FIG. 4 oblique view of the embodiment in an opened active position
- FIG. 5 a detail from FIG. 4;
- FIG. 6 the embodiment in an oblique view in a collapsed position
- FIG. 7 the embodiment in an oblique view in a folded transport position and folded wheel chocks.
- chocks 4, 5 are connected to a sliding and sliding element 3 via their axis of rotation 6 by means of pivot bolts.
- the pivot pins bent to handles 1, 2 are passed through the sleeves of the sliding and sliding element 3 and the elements 9, 10, 11 of the hinged wedges 4, 5 are pushed onto this axis of rotation 6 and secured by means of adjustable stops 7, 8 on both sides.
- the hinged wedges 4, 5 each have a receiving element 9, which is at an angle to the ground in Ge use position and can thus prevent a wheel from rolling.
- the receiving element 9 is preferably designed as a stable plate element or grid and has a receiving surface which shows the wheel during use and can partially accommodate it.
- the receiving element 9 can be pivoted about the axis of rotation 6, one edge of the receiving element 9 preferably running along the axis of rotation 6.
- the hinged wedges 4, 5 have at least one movable hinged element 11 which is arranged between the receiving element 9 and the substrate and fixes the position of the receiving element 9 to the substrate.
- the angle at which the receiving element 9 is fixed can be set in two positions in this embodiment via the position of the folding element 11 relative to the receiving element 9 and the substrate.
- the folding elements 11 are at an angle to the receiving elements 9, lie conditions on these and support them from the ground.
- the receiving elements 9 have retaining lugs on the edge remote from the axis of rotation 6, which hold the folding elements 11 in their position.
- the folding elements 11 are rotatably fastened on the side opposite to the receiving elements 9 on support elements 10 of the hinged wedges.
- the support elements 10 are used for stable Ver connection and support on the ground.
- the folding elements 11 are essentially parallel to the receiving element 9 between the receiving element 9 and the supporting element 10, whereby the receiving element 10 can be pivoted about the axis of rotation 6 and can be brought into a flat position on the supporting element 9.
- the axis of rotation 6 thus also acts as a folding axis.
- the sliding and sliding piece 3 has two telescopic parts, one being inserted into the other and each washer wedge 4, 5 being arranged on a different telescopic part. Both are designed as tubes, with a spring element being arranged in their inner cavity, which is designed as a spiral spring, wherein it is hung on a pivot pin at each end.
- the spring element biases the telescopic parts into a pushed together position in which the device is as small as possible. This enables the device to be quickly incorporated into a compact one Transport position outside of use and requires pressing the wheel chocks 4.5 against the wheels of a vehicle during use. This creates a tight and stable arrangement on the vehicle and leaves as little room for maneuver as possible.
- the inner telescopic part can have one or more openings along its length through which a pin can be guided. In this way, the relative position between the telescope parts can be fixed in a position against the bias.
- the sliding and sliding piece 3 is pulled apart against the direction of the spring and placed against the wheel.
- the spring located in the sliding and sliding piece 3 pulls the hinged wedges 4, 5 towards the wheel, with possible freedom of movement of the wheel being restricted by further contraction of the sliding and sliding pieces 3.
- Inequalities in the ground are compensated for by the possibility of rotating a respective hinged wedge 4, 5 about the axis of rotation 6.
- Fig. 6 the embodiment is shown in which the hinged wedges are closed and receiving element 9, folding element 11 and support element 10 are substantially union parallel and compactly arranged one above the other.
- the embodiment can be brought into an even more compact form of transport, as can be seen in FIG.
- the receiving element 9, folding element 11 and support element 10, which can be rotated via the axis of rotation 6 to slide and slide piece 3, are folded inward.
