LV10757B - Support for bicycle with key - Google Patents

Abstract

This invention (Fig. 3) allows for the stable placement of a bicycle on any surface and theft prevention.The support consists of a body (1), a spoke (2) with supports (3), and a cable (4) with a holder (5) and a lock (6) with a double-arm lever (7) on an axis (8). The support is locked automatically by pulling out the supports (3), as double-arm levers (7) and knobs slide into the socket (12) of the spoke (12). The support is opened with the help of a key (14), which with its teeth (17) pulls the knobs out of a hitch with a spike (2).<IMAGE>

Description

BICYCLES WITH SWITCH

Description of the Invention.

The invention relates to bicycle accessories.

Brackets that help keep the bicycle upright in a slightly oblique position and consist of a spring-loaded and swiveling rod mounted on a bicycle frame are widely used in various bicycle models (USSR a.a. 1746897, SKI E05B35 / 04, 1992). However, such a support prevents the bicycle from being left unattended, as it can be misused. The object of the invention is to provide a bicycle against drowning. This is achieved by providing the support with a locking mechanism that automatically activates by placing the bicycle on the support. The locking mechanism consists of a series of double-lever levers that are individually spring-loaded and freely pivotable with axles, with various lengths at the ends, the levers being mounted in such a way that they can be removed from the coupling with a support using a key. Several variants of the locking mechanism are offered: the bicycle is placed on two spring-loaded sliding supports; the locking mechanism is fitted with a rope which is secured at the ends to holders which can be easily attached to the spokes.

The structure of the bicycle carrier described with the lock is shown in the drawings:

1. - overall view of the support on the bicycle in axonometry / support in the raised position while driving /

2. - overall view of bicycle support in axonometry / support in the lowered and locked position /,

FIG. - lock without top cover / lock open /,

4. - lock without top cover / lock locked,

5. - section A-A in fig. 4.

The proposed locking strut consists of a housing 1 with an inside spokes 2 with struts 3, ropes 4 with holders 5 and locks 6 with two-lever levers 7 per axle 8. Variants 2 are provided.

In variant 1, when the bicycle is parked for a short period of time and within sight, the bicycle is held by hand and pushed with the toe 9 pushing the supports 3 from the housing 1 to the ground level. With the help of spring 10, the supports 3 slide out and hold the bike steady. In addition, one of the bumps 11 of the two-lever arms 7 slides along the surface of the spokes 2 until they reach the seat 12. As a result of the action of the springs 13, the bumps 11 slide into the seat 12 and automatically lock the support.

To unlock and lift the stand, insert the key 14 into the key hole 16 on the shaft 15 and turn it. The key with its teeth 17 removes all the bumps 11 of the two-lever lever 7 from the seat 12 of the cane 2. Then, with the help of the foot or the hand 9, the cane 2 lifts the cane 2 with the support 3 in its upper starting position. Conversely, the bumps 19 of the double lever arms 7 serve the purpose of making it more difficult to open the key with the knob, since the bumps 11 tend to slide into the socket 20 and lock the spokes 2 when removing the cams 11 from the socket 12.

In variant 2, when the bicycle is left unattended for a prolonged period, the cable 4 is introduced between the bicycle wheel spokes or stationary frame and the cable 4 holders 5 are inserted into the opening 21 on the cane 2. Further, by pressing the foot 9 the rope holders retracted together with the spokes 2 in the housing 1, where they hold in the grooves 22. In this way, automatic and simultaneous locking of the supports 3 and the rope 4 takes place. To raise the strut and release the cable, use the key as described in the first version.

The use of the proposed device will significantly reduce the chances of stopping the bike and allow it to be placed securely on any surface.

Claims (3)

INVENTION FORMULA 1. Bicycle support, comprising a pivotable spring-loaded core, characterized in that, for safety reasons, it is equipped with a locking mechanism consisting of a series of double-lever arms which are individually spring-loaded and pivotable about the axle, with the arms mounted at different ends. such that, at the same time, all their bumps can be removed from the coupling with a support rod by means of a key. 2. Support after p. 1 differs in that the bike is positioned on two spring-loaded outriggers. 3. The strut according to claim 1, characterized in that it is equipped with a rope which is fastened at the ends in brackets which can be easily attached to the spokes.
