Description

"Length-adjustable two-wheel support"

The innovation relates to a length-adjustable two-wheel support consisting of an upper part (support base) and a lower part which are slidably and lockably connected to one another.

With two-wheel supports of the aforementioned type, the total length of the supports can be adjusted to the respective height of the Adjust the bicycle frame or to different wheel diameters.

In known bicycle supports of this type, two displaceable parts with a compression fitting in the each desired length held. If the clamp fastening is loosened, the length of the column base can change and thus the stability of the parked two-wheeler can no longer be guaranteed.

The innovation is based on the task of training a two-wheel support of the aforementioned type so that the Durability of the set length is guaranteed in the long run, with the conditions for a Economic production should also be given the possibility of self-assembly by the user.

The solution to this problem results from the features of the protection claims.

When assembling this bicycle support, the tube sleeve is pushed onto the support base up to the length, whereby for one of the two recesses on the column base can be used to accommodate the indentation on the tubular sleeve. After reaching the desired length, the pipe sleeve is rotated a little until the indentation in the nearest one Notch into place. Tightening the self-tapping screw makes this setting secure against rotation. The permanent one Durability results from the fact that the connection does not even work after a possible loosening of the screw can be resolved because aie transferring the burden

The notch and the screw itself advises that the force is transmitted via the indentation is not directly involved. The elements provided for the connection on the column base can be used during casting can be produced so that a special operation is not required. The assembly of the two-wheel support after the innovation - in particular the adjustment to length - is so easy that it can also be used by the bicycle user can be carried out.

According to the further innovation, recesses are provided on both sides of the notches on the column foot, which creates a Receives cross-section, which requires a minimum of material in the production.

By a further measure according to the innovation, which consists in the fact that a conical recess in each notch is provided for receiving the screw tip, the durability of the anti-twist protection is even more special Dimensions secured. The connection between the column base and the pipe sleeve can be made particularly easy if necessary make sure that one provides several indentations on the pipe sleeve instead of one, in all to snap into place can be brought with a corresponding number of notches.

An embodiment of the innovation is described in more detail below with reference to the enclosed Drawings.

Fig. 1 is a side view of the operational one

Two-wheel support according to the innovation , with the

Connection area of the items is shown cut;

Fig. 2 is a cross section according to II-II of Fig. 1;

3 shows a longitudinal section through the tubular sleeve (lower part);

4 is a longitudinal section through the lower region of the support foot (upper part);

Fig. 5 is a plan view and a side view of the column foot in the area of a notch.

The two-wheel support consists of an upper part or support base 1 and a lower part, which is a tubular sleeve 4 is. At the top of the support base are elements for fastening to the bicycle frame. There is a surface at the bottom of the pipe sleeve Formed for installation on the floor. The column base is cast and partly inserted into the tubular sleeve.

On the support base 1, several notches 2 are formed at a constant distance on the side facing the two-wheeler. A small conical recess 2a is formed in the center of each notch (Fig. 5). Notches and co-

Recesses can be poured without additional work steps in the manufacture of the column base.

As can be seen from FIG. 2, two concave recesses 3 are shown over the lower half of the length of the support foot educated. The tubular sleeve 4 is attached so that it can be pushed onto this lower part of the support base. she owns at its upper end an indentation 5 which is formed towards the inside of the sleeve and which encapsulates the cast in the column base 1 Notches 2 is matched exactly. A punched hole 6 is provided on the tubular sleeve under the indentation.

During assembly, the sleeve 4 is pushed onto the support base 1 until the desired total length of the two-wheel support is reached. The indentation 5 can slide in one of the two recesses 3. The sleeve is pushed until the desired total length is reached. The sleeve is then rotated until the indentation 5 engages in the closest notch 2. By means of a self-tapping screw 7, received by the punched hole 6, the sleeve is secured against lateral rotation by being screwed in. The tip of the self-tapping screw 7 is received by the conical recess 2a.

The weight load exerted by the bike on the support is absorbed by the indentation and notch, so that even if the self-tapping screw is loosened, the length of the column base cannot change.
