Claims

The invention relates to a device for attaching the seat support of grass mowers on their main frame, in which a weakening of the support by screw holes is avoided and the lower end of the support engages a slot in the main frame. In the known devices of this type if the fastening screw is heavily stressed by the pressure exerted on the support, whereby the fastening device will soon become loose. In addition, the necessary for attaching the support makes it difficult Approach the molding and pouring of the frame. According to the invention, the lower bent rests End of the seat support on the frame tube and is held behind the latter by an eyelet-like clamping piece, this is done by means of an adjusting screw reaching under the frame tube against the frame tube is supported. This attachment has the advantage that on the one hand the shaping of the Frame is not made difficult by bulky parts, on the other hand, loosening as a result of the force exerted by the driver cannot occur because this weight is the Fastening screw is not loaded, but relieved.

An exemplary embodiment of the subject matter of the invention is shown in the drawing.

Fig. Ι shows a front view of the fastening device,
Fig. 2 is a cross section,
Fig. 3 is a rear view.

Fig. 4 and s show in side view and plan the seat in connection with the Chassis of the mower.

A short, horizontal rag is cast on the main frame tube g and contains a slot h directed obliquely from top to bottom. The flat steel seat support / is bent at its lower end to match the shape of the frame tube and inserted into the slot Λ, where it rests against the wall of the slot Ii at the front and rests with the curved part on the attachment surface b of the main frame.

An eyelet-shaped clamping piece c made of malleable cast iron grips with its upper leg / over the seat support / and with a rag k under the frame tube g, with its front side / resting on a corresponding attachment surface m of the frame tube. In the flaps & is there any adjustment screw? with a square head inserted, the tip of which is inserted into a notch e in the frame tube. The seat support is held in place on the side by ribs.

It can be seen that the seat support / rests firmly against the two contact surfaces of the frame tube in the pressure direction indicated by an arrow ο. By tightening the Sdhraubei? the seat support is secured in its position against vibrations and adjustment by pulling it firmly downwards through the leg / bracket c. The force created by the load on the seat ο does not exert any stress on the screw, but can only relieve the screw so that loosening cannot occur due to the load on the seat.

It should also be emphasized that in the arrangement according to the invention, the seat support is not weakened by any drilling.
