Mounting arrangement for bicycle shoe brakes

The invention relates to an arrangement for the assembly of Shoe brakes on bicycles of all kinds. With the new one Assembly or mounting arrangement should do the job be released, bicycle shoe brakes or rim brakes centered in their relabiv to the wheels to be braked To hold on securely.

It is known that shoe or rim brakes are exposed to shock loads and vibrations during assembly and during their use, which can cause an angular change in the centered position provided for the brakes. Even if the pin supporting the two jaws and holding the entire brake on the bicycle frame is installed precisely and carefully, this jeopardizes safety when driving the bicycle equipped with the brake and adversely affects the

Brake efficiency due to incorrect centering of the brake shoes in relation to the wheels poor or delayed braking and wear and tear on those in the disengaged position Brake shoes can result. Occasionally this can also lead to the brake unintentionally with other than the parts of the bath having the braking surfaces comes into contact, which leads to a fall or to injury to the person using the bicycle.

All of these inconveniences are addressed in the present invention Fastening arrangement excluded by the fact that a disk made of hard between the head piece of the pin and the bicycle frame on the pin Material is placed, the opposite end faces with it in the head piece and the Frame cutting projections are provided.

An embodiment of the invention is described below Part of the description described with reference to the drawings. In the drawings shows:

1 and 2 in front view and top view

a shoe brake attached to the front fork of a bicycle;

Fig. 3 in view and section of a washer which is used in the fiction is appropriately provided with incisive devices; and

Fig. 4 is a plan view of the better te mounting arrangement for bicycle shoe brakes using the disc shown in FIG.

The illustrated in Fig. 1 and 2, designated as a whole with 1 bicycle shoe brake has in known Way two with brake pads 4 provided jaws 2 and 3 on. The two jaws are mounted on the pin 5, which is fastened to the bicycle frame 6 by means of the nut 7. With the conventional fastening method the head piece 8 of the pin 5 is supported directly or under the brakes that have been customary up to now Interposition of the concave disk 9 on the frame. Obviously need to achieve an even Braking the brake pads 4 from the tire or from the rim 10 of the wheel have the same distance and it is therefore essential that the pin 5 supporting the brake does not move after it has been fastened may be adjusted more angularly relative to frame 6, but this is often the case with prolonged use of the brake.

According to the invention is now the attachment of Brake on the frame with the help of an additional component that consists of a special disc 11 of the in the type shown in FIG. This disk 11 has a hardened circumferential toothing, which by a rolling process is generated in such a way that also on the opposite end faces of the disc along the entire circumference of which sharp, blade-like projections are formed. This disc is between the head piece 8 of the pin 5 and the bicycle frame 6 placed on the pin. Usually is, as shown in the drawing, still the concave disk 9 between the disk 11 and the frame 6. The concave disk can also be omitted. During assembly, if after centering the brake pads 4- the nut

7 is tightened, the special disk 11 between the Head piece 8 and the concave disc (or the frame) pressed together. Ba the protrusions or Elevations of the disc 11 harder than the usual ones for the head piece 8 and for the frame 6 or the concave disc 9 are materials used, they penetrate at least partially into these parts and remain firmly connected to them. In this way they cause a rigid connection, so that without Loosening the nut 7 a change in the mounted position of the brake is practically impossible. on in this way a relative pivoting of the brake relative to the bicycle frame is prevented with certainty.

The fastening arrangement described can be in many Respect. In particular, the shape of the disk 11 and that provided on it incisive holding devices on one side or the other end face of the disk is also designed differently than in the illustrated embodiment be. For example, the retaining devices can be designed in the shape of a point or a wedge.

The mounting arrangement according to the invention, although described above in connection with the fastening of bicycle brakes is described, advantageously in other areas of the Technology find application on which a designer must deal with the problem as described in the described application corresponding way a mutual angular adjustment of can prevent two parts connected by means of a pin or pin.
