Reflector holder in bicycle pedals

Bicycle pecfele have to be almost worldwide with reflectors on both Sides of the pedal. This makes them more useful and the most inexpensive to assemble design is of particular importance.

For most of the steel pedal models on the European market are the reflectors on the outside of the pedal side parts with the help of screwed or riveted Boxes attached, these boxes being screwed, riveted or suspended with the pedal frame.

There are also known plastic sockets of the reflectors are placed on the pedal frame from the outside and by means of rear dovetail-shaped extensions on the bottom of the Reflector holding body are fixed there.

All externally attached reflectors have the disadvantage that they can easily be damaged or pushed off by the shoe heel when stepping on or by touching the floor.

Steel pedals are also known on the market, where the deepened attached reflectors in additional U-shaped troughs are stored, but do not hold the reflector itself, so that with the latter on lateral extensions that are behind the Place the pedal frame, cannot be compacted. This requires a method of assembly with a high level of technical effort Automation.

Other well-known steel pedal models with internal Reflectors can also not do without the extensions on the reflector and effect the adaptation of the reflector to the inside of the frame through differently angled and shaped frame pieces. Here, too, the disadvantage lies in the complicated tool design for manufacturing the pedal frame, which is difficult Installation of both reflectors simultaneously from the inside in the closed pedal frame, increased technical effort for reshaping the bends and bends formed from the pedal frame with the risk of not being backlash-free Final storage of the reflector or its damage during Installation with the necessary contact pressure in order to achieve a firm fit of the reflector despite the spring deflection.

The purpose of the present invention is to create a unit of reflector and fastening elements with the aim of an inexpensive installation option in the pedal frame that can be fully automated with minimal effort, while at the same time providing a deeper end storage of the reflector ^: within the pedal frame. The latter completely eliminates the risk of damage or repulsion and makes it possible to achieve a secure fit of the reflector element with a simple shape, since the reflector is not exposed to any pressure or impact stress in its end position.

The purpose of the invention of a

a) Inexpensive design of the reflector element

b) Storage of the same within the pedal frame

c) Fully automatic installation option by simply pushing in the reflector unit from the outside

was achieved as follows:

In the preferred solution, the reflector 1 gets on its bottom 2 welded to the reflector body on the side raised cheeks 3, optionally around the reflector or only on both narrow or both long sides. the the latter version is shown.

The reflector base, which is now formed in the shape of a VU profile due to the side cheeks, only requires a slightly higher amount of plastic material, whereby in the case of the cheeks which are only formed on two sides, as shown, an extruder process is also possible at low cost. The ultrasonic welding to the reflector is carried out in the same way as before. _;

The side cheeks have surrounding strips 5 or individual Stool 5 or segments trimmed on three sides, slightly angled towards the outside, which are positioned after the reflector has been pressed in hook behind the metal frame and prevent the reflector from falling outwards.

The locking of the reflector element at the desired height and protection against unintentional pushing in of the reflector cause the angles ή- formed from the side cheeks, around all four sides or only parts of them, the lie against the outside of the steel frame 6.

The pedal frame 6 can be provided with embossed beads 7, which form an additional protection of the reflector and the fastening elements.

The customary conicity ^ as shown in the drawing, can be used to create a space 11, whereby the side cheeks when the reflector is pressed in move from the outside towards the reflector and cause the desired snap effect when the strips o. q. 5 at Push in the reflector behind the inner edge of the frame window as soon as it is determined by the outer strips The final position for the reflector assembly has been reached.

When choosing a suitable material with inherent springiness or elasticity, the conicity of the reflector can be influenced be waived, especially if you accept a slightly larger window in the pedal frame.

The solution is also to use a reflector with a base that is already welded on, ■ ewdeg-lldingo-onfoll · » 4en — clerfeefHia ebp £ -, and these to be placed in a separate tub or a U-profile made of plastic or metal. This retaining element should be the same or have similar outer locking formations as prescribed, plus formations inward to the Reflector out, which insert into corresponding recesses in the reflector and prevent the latter from falling out. Since practically no outwardly acting forces can occur on the reflector fastened inside the pedal frame the clamping elements, which counteract such a direction of movement, are kept very small.

The reflector element 1, 2 and 3 and the multi-part design described above can also be used for so-called block pedals can be used as shown in part B of the drawing. The advantage here is that the reflector is in the pedal block can also be used retrospectively with support plates 10 that have already been installed. With the commercially available reflector version with relatively long formations on the narrow sides of the reflector, the assembly is the pedal block + Reflector + profile sheet because of the necessary deformation (bending) of the pedal block for inserting the reflector problematic and prone to failure in automatic operation.

A widening or lengthening of the welded-on reflector base is conceivable with over the reflector delimitation to provide laterally protruding resilient segments, strips or the like, which also a Falling out of the reflector and still easy assembly prevent by taking advantage of conicity or elasticity. The possibility of impressing the reflector would then be to be switched off by the fact that the reflector body also has protruding strips on its upper edge, which, as shown in the drawing similar to A-, on the edge of the pedal frame. The fact of the deepened, shock-protected storage would then still be due to the existing beads 7 given on the steel frame.
