TOWBAR

The present invention relates to a car towbar comprising a runq, an axle with towbars, a lock and a vertical lock. The device according to the invention is suitable as a towbar for passenger cars or similar vehicles.

The number and use of passenger cars has been constantly growing. In addition to traditional passenger transport, the passenger car is increasingly being used as a towing vehicle, with the car being fitted with a towbar for the trailer. Usually, such a towbar is fixed to the car, extending to the outside of the car's bumper.

A towbar sticking out of the back of a car obscures the look of the car. In some car models, the towbar is located in front of the license plate, in which case the location of the plate must be moved and this causes additional costs as well as tarnishes the appearance of the car. Above all, the fixed towbar causes unnecessary damage in the rear, whereby the vehicle behind it collides with the towbar. In such a situation, the elastic buffer is not useful.

Towbars are already known which are equipped with a folding mechanism in which the hook is turned under the car. Such devices are expensive and cumbersome to use. The hook under the car is easily soiled and must be cleaned every time it is used.

The towbar according to the invention is characterized by what is stated in the claims below.

The towbar according to the invention can be removed, whereby the car retains its original shape. The construction of the towbar is dust-tight and dirt does not make it difficult to attach or detach the towbar. 3The buffer is available when the hook is switched off. The installation of a towbar according to the invention in a car does not require the transfer of the number plate.

The accompanying drawings illustrate a towbar according to the invention. Figure 1 illustrates the position of the towbar in the car.

Figure 2 shows the body part of the towbar.

Figure 3 shows the towbar shaft and knob.

Figure 4 shows a side view and a cross-section of the towbar.

In Figures 1 ... 4, the number 1 means the axis of the towbar and the knob to which the counterpart of the towed device is attached. The number 2 shows the body part of the towbar into which the axle is pushed. The number 3 indicates the oysty lock. The vertical lock is pressed into place by a spring 7 with a protective rubber 8 on it. At the opposite end of the Runqon 1 there is a dust cover 6. The body part is welded with mounting plates 3 which receive the tensile stress caused by the hook. The shaft end locking part 4 locks the hook in the vertical position by means of the vertical lock 3. When the towbar knob and the shaft 1 are removed, the body part 2 can be closed with a dust-tight plug 9.

The attachment and removal of the towbar is carried out as follows: The protective cap 9 of the body part is removed and the shaft 1 is pushed into the body part 2. The sides of the end of the shaft opposite the knob are milled straight so that the shaft can be pushed all the way past with the knob 5 of the mounting plates in a horizontal position. At the mounting plates, the shaft is thinned to allow it to rotate freely. When the knob is then turned to the vertical position, the spring 7 presses the vertical lock 3 into place, because the straight bevels in the body part 2 and the straight, surface surfaces of the shaft end lock part A are then in the same planes.

The hook is removed by pulling the sleeve-like vertical lock 3 off the body part and the shaft lock part and by turning the knob 90 °, so that the shaft can be pulled out of the body.

Claims (3)

72930 A detachable towbar or the like of a car, comprising a body part (2), locks (3, 4) and a shaft (1) which can be inserted into a tubular body part, one end of which acts as a towbar, characterized in that the opposite towbar of the shaft (1) the sides of the head are formed straight and the shaft (1) further comprises a thinning at the mounting plates (5) of the body part (2), the shaft (1) being locked in its longitudinal position by pushing the towbar horizontally into the body part (2) and then twisting the towbar to the vertical position when the fastening plates (5) are at the thinning in the shaft (1), and that the sleeve-like vertical lock (3) comprises planar surfaces in its bore and the towbar end (4) of the shaft (1) comprises planar surfaces and the body part (2) the head comprises planar surfaces, whereby the locking of the hook to the vertical position takes place by a sleeve-like vertical lock (3), which binds the planar surfaces at the end of the body part (2) and at the end (4) of the shaft (1) with their planar surfaces sa parallel. Detachable towbar according to Claim 1, characterized in that the vertical lock (3) is provided with a spring (8) which presses the vertical lock (3) into the bottom position when the hook is upright. Detachable towbar according to Claims 1 and 2, characterized in that the locking mechanism is dust-protected when the hook is closed by a dust cover (6), and that the body part can be protected by a plug (9) when the hook is removed.
