STATE OF THE ART

In internal transport systems, which are used for the carriage of goods and material, are nowadays by means of drawbars detachable transport vehicles used, which are pulled by traction devices, such as Gabestablern, for example, from a warehouse to an assembly line. When coupling the trolleys with other vehicles or the traction devices, it is necessary for safety reasons to fix the trolleys on the ground, in particular a level floor, so that unintentional rolling away of the trolley is avoided. In order to achieve this condition nowadays wheel brakes are used in large numbers, which are mounted directly on the castor wheels of the trolleys, especially on the front two castors, and are operated by an employee with his foot, resulting in a high expenditure of time and a high material wear goes hand in hand, since the castors have a low overall height, in particular between 100 to 200 mm, and sit under the trolley and are not generally accessible in a simple manner.

WAYS FOR CARRYING OUT THE INVENTION

In the 1 to 5 is an embodiment of a device according to the invention 50 for fixing on a substrate U and coupling a movable transport device 60 shown.

In this case, a horizontal corridor is described with the term subsurface U, wherein the direction orthogonal to this direction is called vertical. The underside of the attribute is equivalent to the substrate U facing away on the upper side corresponding to the substrate U.

The device 50 stands with the transport device 60 in detachable connection and consists of a pivoting unit 10 , a frame connection unit 20 and a fixation unit 30 together. The swivel unit 10 is rotatable in the frame connection unit about a horizontal axis of rotation, which is indicated in the figures by the reference AB 20 stored present, which with the transport device 60 , in particular a frame of the transport device, in connection. The free end of the swivel unit 10 can in the pivoting direction, which is indicated in the Fig. With the reference numeral F1, is guided about the axis of rotation AB. In addition, the pivot unit 10 Also rotatably provided in the opposite direction pivoting, which is not shown in the Fig.

The swivel unit 10 is composed of an elongated drawbar 11 , a driver 12 and a detachable, in particular screw-on, coupling element 14 together and lies in a lower position, which in 1a is indicated by the reference symbol W, in particular the horizontal position, in addition, via a damper element 24 , damped stored at the top of the frame connection unit 20 at. In the vicinity of the damping element 24 is on the frame connection unit 20 a stop element 23 at the top of the frame connection unit, which is designed as a set screw and a minimum distance between the pivot unit 10 and the frame connection unit 20 , in particular between 20 and 50 mm guaranteed. At the frame connection unit 20 is a locking element 21 , which is designed, for example, as a pawl with spring pressure, available, which is designed so that it is the pivoting unit 10 in the upper position, the in 1b is indicated by the reference numeral O, in particular against the pivoting direction F1, fixed and by actuation of a switch 22 , in particular foot or hand switch, the swivel unit 10 releases.

Will the pivoting device 10 by pivoting in the pivoting direction F1 in the upper position, in particular the vertical position, the pivoting unit is guided 10 by means of the locking element 21 fixed in this position.

In a further, not dargestellen embodiment, it would also be conceivable that the underside of the pivoting unit 10 in the lower position W directly on the front side of a screw, which in the Rahmenanschlusseinheit 20 is screwed, rests and thus the lower position W of the swivel unit 10 is fixed by the adjusting screw, so that the adjusting screw, the swivel unit 10 opposite to the pivoting direction F serves as a stop.

In a further, not dargestellen embodiment, it would also be conceivable that the locking element 21 is designed so that the pivoting unit 20 stepwise or in all angular positions or the lower position W, in particular the horizontal position, can be fixed.

By pivoting the swivel unit 10 in the pivoting direction F1, which is on the drawbar 11 sitting takers 12 with a in the direction of displacement, which is indicated in the figures by the reference numeral V, the underground U opposite displaceable fixing unit 30 , in particular longitudinally displaceable fixation profile, brought into operative connection. The fixation unit 30 has a bottom-mounted stopper element 32 , which is formed for example of plastic and resiliently by means of a spring element 31 , in particular coil spring, on the frame connection unit 20 is arranged. The spring element 31 is for example between the top of the fixation unit 30 and the frame connection unit 20 arranged.

By pivoting the swivel unit 10 in the pivoting direction F1 this is with the fixing unit 30 brought into operative connection, whereby the fixation unit 30 in the direction of displacement V against the effective direction of the spring element 31 is guided against the underground U. This is the fixation unit 30 brought into operative connection with the substrate U (pressure contact), which is shown in detail 4b is illustrated and to a fixation of the device 50 , or the transport device 60 leads so that the transport device is secured in this position. Will the swivel unit 10 by actuating the locking unit 21 released again and brought into the lower position W, in particular horizontal position, is the fixing unit 30 by means of the spring element 31 from underground U upwards pushed and the transport device 60 released from the underground U for further transport.

For fixing and / or stopping is therefore only the pivoting of the Arritierelement 21 shared swing unit 10 from the lower position W, in particular horizontal position, in the fixed, upper position O, in particular vertical position and for the function of driving the pivoting of the pivoting unit 10 from the fixed, upper position O, in particular vertical position, in the lower position W, in particular horizontal position, necessary, without having to operate wheel brakes or other braking and / or fixing devices.

Stopping, or stopping the trolley by the use of the device described 50 , always takes place in that the operating personnel, the swivel unit 10 in a vertical position, or nearly vertical position, brings the fuser unit 30 is guided against the ground U, so that the safety of the operator is not by a horizontally standing in the room pivot unit 10 , in the form of a "horizontal trip-trap", is endangered.
