Bicycle pedal

The present invention relates to a bicycle pedal, in particular to a bicycle pedal that is easy to maintain and clean and can be manufactured at reduced costs.

Sports pedals usually have a device attached to them that helps to fix the foot on the pedal and allows the pedal to be pulled away from the foot during the upward movement. Initially, this was achieved using racing hooks. In modern pedals, shoes and pedals are equipped with a mechanism so that hooks mounted on the sole of the shoe can lock firmly onto the pedal. Such a design requires a large number of components and assembling them is not only relatively laborious and rather impractical, but also expensive to manufacture and assemble, and it would also be laborious to maintain and clean.

A conventional click pedal, where the shoe is connected to the pedal via a binding. The foot can be released again by a twisting movement. With click pedals, force can be exerted both when the foot moves downwards and upwards. As is well known, a conventional click pedal essentially consists of a hollow crank, a pedal axle, a front stop and a spring element, whereby the front stop is articulated on the inside of the crank and axially supported, a bolt is attached to the outside of the crank from front to back and a screw tube is additionally screwed to this bolt so that one end of the spring element can be attached to the screw tube and another end of the spring element can be attached to one end of the front stop in order to be able to move the connection downwards and upwards as required and the shoe can be connected to the pedal via this binding (clickies).

In the case of a conventional bicycle pedal as mentioned above, the crank must be hollow and the manufacturing costs are significantly higher due to the higher precision required. It is also more difficult to assemble the screw tube, front stop and spring element. In addition, the permanent bending strength of the movements of the spring element can lead to fatigue of the bicycle pedal and can affect the quality of the pedal construction.

Another conventional bicycle pedal, as shown in Fig. 2, essentially comprises a crank, an upper limit piece, a side limit piece and two spring elements, the upper limit piece being on top of the pedal body and the side limit piece being on one side of the pedal body, and two spring elements being additionally mounted between the upper limit piece and the side limit piece. The side limit piece can be moved elastically. With such a construction, the upper limit piece and the side limit piece must be precisely aligned during assembly. The high precision of these two components not only results in increased defective products but also in difficult assembly work. In addition, the side limit piece can be displaced due to permanent voluntary force absorption, which means that proper use of the pedal cannot be guaranteed, i.e. the side limit piece can only be adjusted outwards in one direction and is not suitable for adjusting inwards in another direction. A conventional bicycle pedal with the above construction is therefore disadvantageous.

The invention is therefore based on the important task of designing a bicycle pedal of the type described at the beginning in such a way that it essentially consists of a pedal body, a protective board and a spring device, with an insert part for receiving the protective board and the spring device on one side of the pedal body and the spring device consisting of a guide piece and two spring pieces and serving to elastically secure the protective board, so that the protective board and the spring device can be assembled with the pedal body quickly and easily. In addition, a bicycle pedal in this advantageous construction can be manufactured at reduced costs and can also be easily and effortlessly maintained and cleaned.

The stated problems are solved by the features specified in the protection claims.

A bicycle pedal essentially consists, as shown in Fig. 3, Fig. 4 and Fig. 5, of a pedal body (10), a protective board (20) and a spring device (30).

The pedal body (10) is designed in the form of an oval geometry and comprises a pedal axle (11) for connection to the bicycle body (not shown in the drawing). On one side of the pedal body (10) there is a recess (12) for the articulated axially mounted reception of the protective board (20) and the spring device (30). A through hole (121) is arranged at the appropriate position on each of the two sides of the recess (12), and one hole (121) of this can be arranged in a not completely externally drilled through version for screwing a bolt (41) into it. A closure piece (13) is additionally attached protrudingly at the appropriate location in the middle section of the inside of the recess (12). A projecting boundary surface (14) with an external bevel is formed on each of the two sides of the inside of the recess (12). To prevent the feet from slipping, a majority of anti-slip devices (15) have been installed on the pedals.

The protective board (20) is L-shaped and its upper edge opposite the pedal body (10) is designed in the form of an attachment part. Two parallel struts (22) are attached to the lower part of the protective board (20) so that these two struts (22) can be inserted exactly into the recess (12) of the pedal body (10) and can be firmly screwed to the pedal body by means of a bolt (41). The two surfaces of the struts (22) opposite the inside of the recess (12) are designed in the form of a bevel (221) with a corresponding radius.

The spring device (30) consists of a guide piece (31) and two spring elements (32). The guide piece (31) can be firmly screwed to the locking piece (13) of the pedal body (10).

Wow

The two spring elements (32) can be axially mounted in an articulated manner between the two through holes (121) of the pedal body (10) and between the two struts (22) of the protective board (20) by means of the bolt (41). A stop (321) can be attached in a protruding manner to both ends of the two spring elements (32), whereby one stop (321) can be pressed firmly and supported on the inside of the protective board (20) and another stop (32 V) on the rear wall of the guide piece (31) in order to secure the protective board (20) in a form-fitting manner.

As can be seen in Fig. 6, the interface (14) of the pedal body (10) and the surfaces of the two struts (22) of the protective board (20) are designed as a bevel. The bevels (221) of the two struts (22) are designed parallel to the bevels of the interface surfaces (14). After inserting the two struts (22) into the recess (12), the two struts (22) can come into contact with the two interfaces (14) and the protective board can only move in one direction, i.e. only along the radius of the two struts (22) and cannot move in the direction of the pedal body (10), thus preventing any adjustment of the protective board (10) and thus ensuring a stable arrangement of the protective board (20).

With the above-mentioned advantageous design, a bicycle pedal can be manufactured at reduced costs and can also be easily and effortlessly maintained and cleaned.

A bicycle pedal is described which essentially consists of a pedal body, a protective board and a spring device, characterized in that an insert part for receiving the protective board and the spring device is provided on one side of the pedal body, the spring device consisting of a guide piece and two spring pieces and serves to flexibly secure the protective board, so that the protective board and the spring device can be assembled with the pedal body quickly and easily. With this advantageous construction, a bicycle pedal can be manufactured at reduced costs and can also be easily and effortlessly maintained and cleaned.
