Pedal for bicycles

The invention relates to a novel and particularly useful pedal for bicycles and other bicycles.

The aim of the present invention is to provide a simple yet useful pedal for bicycles and other bicycles which can easily be manufactured economically with the aid of automatic machines.

A pedal according to the invention consists of a pedal frame with side parts arranged at a distance in the longitudinal direction the pedals, a pedal bearing drum arranged symmetrically between the side parts and a pedal block on each side of the drum, which is adapted to the shape of the drum and the .jeitenteile.

The top parts preferably have one or more

Projections and recesses corresponding to the pedal blocks for their inclusion in order to facilitate their mutual position and attachment.

The invention will now be based on two exemplary embodiments to be described according to the accompanying drawing · It is.

Fig. 3 is a plan view of a pedal according to a second embodiment and

FIG. 4 shows a section along the line IV-IV in FIG. 3.

Fig. 5 is a partial view of a still slightly modified embodiment of the pedal frame.

According to Figures 1 and 2 of the drawing, a pedal according to the invention consists of a frame with spaced apart and side parts 11 parallel to each other, a bearing

drum 12 which extends in the longitudinal direction of the frame and is arranged symmetrically to the side parts 11, as well as from two pedal blocks 13, each of which is laterally of the storage drum or between the drum 12 and the side parts 11 is provided.

The pedal frame consists of a substantially U-shaped Component whose legs, which are arranged at a distance from one another, form the side parts 11, as well as an end plate 14 extending across the open end of the U-shaped Component extends and has slots 15 at the ends to receive inwardly stepped retaining tabs 16, which form the extensions of the side parts 11 and, after insertion, the slots 15 for holding the end plate in place 14 serve in the right position,

Each side part 11 has an inwardly open and substantially over the entire length extending channel, while the third side 17 of the U-shaped component the has the same shape as the end plate 14. The third side 17 and the end plate 14 both have openings to the To accommodate pedal bushings 18, which are supported by a pedal

The pedal blocks 13, seen in cross section, have a predominantly rectangular shape and of two opposite longitudinal · surfaces of these blocks has a recess in the form of a partial cylinder 20, which fits snugly against the bearing drum 12 applies, the other a contact surface 21 which fits into the channel-shaped side parts.

The pedal is held on its axis by means of an eccentric locking washer 22, which is in one on the circumference provided groove 23 at the end of the pedal axis 19 fits, the locking washer 22 within this annular groove through an end cap 24 flanged onto the end of the bearing bushing is held in the correct position.

According to a second embodiment according to Figures 3 and 4, the pedal frame has a predominantly rectangular shape and is made of strip-shaped material, with the ends 31 and 32 of the strip overlap as shown in the drawing. The side parts 33 have each has a recess 34 in the form of a partial cylinder, which extends along the outer sides and by shifting the

opposite outer edges 33 'emerged to the outside is.

The pedal blocks 35 have a recess 36 in the form a partial cylinder for receiving the bearing drum 37 similar to FIG. 1, while the opposite side deviates from the arrangement according to Figures 1 and 2 is also equipped with a recess 38 in the form of a partial cylinder, in order to be able to sit comfortably on the inside of the correspondingly shaped side part «

The pedal bearing bushes 39 are arranged as already described and here, too, the pedal is held on a pedal axis 40 with the aid of an eccentric locking washer 41, which is held in the correct position by an end cap 42.

In the 2Hammbau of the described pedal, the Storage drum, the length of which is essentially the same, but not greater than the corresponding Innenaass of the frame is brought between the pedal blocks, whereby it is inserted into the corresponding side panels. Thereon

The pedal blocks are then twisted out of the frame around their side parts, leaving room for insertion created the pedal drum and pressed the pedal blocks into this space. Then the bearing bushings inserted, the pedal axle is inserted, the locking washer is brought into the correct position and Finally, the end cap flanged onto the bearing bush. This completes the assembly.

Another embodiment for the pedal frame is shown in FIG Fig. 5 shown, after which the frame from a single strip of tape material in the form of Flg. 3 is bent. Instead of the overlap of such a tape strip in the vicinity of the pedal bearing bushings meet the adjacent ends of the tape strip at one corner of the pedal and are connected to one another by projections and depressions.

Of course, in the case of the pedal according to the invention, the parallel side parts can also be arcuate as any changes can be made, provided they are within the scope of the present invention lie.
