Description

Bicycle maintenance bracket for maintenance work

State of the art

1. Bicycle mounts as floor-standing devices

a) usually U-shaped stand placed on the ground, which is usually positioned under a wheel or at the bottom bracket.

• Maintenance work only possible in a crouched position

• Wheel/wheels are hardly accessible and cannot be moved freely, therefore no adjustment work on the gearshift is possible

• the entire device is extremely unstable - especially when loosening very tight screws or when working with both hands, the mounted bike tends to tip over along with the stand.

b) a device placed on the ground where the bicycle is usually hung/mounted at two points on the frame.

• Maintenance work only possible from one side, as the stand on the other side of the bike is in the way

• Working height too low

• The entire device takes up a lot of space because it tries to counteract its instability by making it heavy.

2. Bicycle holder mounted on the wall

a) in particular two brackets coming from the wall to which the bicycle is mounted

• Maintenance work only possible on one side

• only a bicycle of a certain size can be mounted here, as the bracket must be adapted to the corresponding bicycle when mounted on the wall. Families who have bicycles of different sizes and designs in particular cannot use the wall bracket once it has been mounted for all bicycles.

b) Device where the bicycle is placed on a rail mounted on the wall

• is for storage purposes only

3) Bicycle holder attached to the ceiling

a) a device mounted on a ceiling, from which three hooks usually go down, onto which the bicycle is hung by the handlebars and saddle

• Working height not adjustable

• too unstable (the bike rocks)

• mainly used for hanging bicycles

b) similar devices as a) for storage

Summary/Sources

A characteristic of all devices is that they are either only used for storage or are too unstable, take up too much space, have a working height that is too high or too low and attaching the bike is usually too difficult for one person.

problem

The invention specified in claim 1 is based on the problem of creating a rotatable and height-adjustable bicycle maintenance holder which is tilt-proof, guarantees a firm seat for the bicycle, takes up little space, enables working in an upright position and in which, due to the possibility of rotating the bicycle on its own axis, no frequent change of location is necessary for maintenance work.

Solution

This problem is solved with the features specified in claim 1.

Benefits achieved

The invention means that all bicycle parts and accessories can be reached with both hands, and everyone can set the optimal working position for themselves or change it at any time thanks to the ability to rotate the assembled bicycle around its own axis. The height adjustment means that both tall and short people can work in an upright position. In addition, the bicycle maintenance bracket can also be attached above a workbench, table or similar if space is tight. Wall mounting is also possible, with the bicycle hanging vertically from the floor. All bicycles available on the market can be attached to the maintenance bracket by inserting the spacer sleeve (Figure B) in the seat head sleeve (see the example below). This has the advantage that once the mounting plate (1) with welded-on pipe section (2) has been attached, bicycles of all different types can be hung on a pipe (4). In addition, the position of the pipe (4) at an angle of approx. 15 degrees ensures that the assembled bicycle is in a horizontal position.

Example

An embodiment of the invention is explained using Figure A. It shows the mounting plate (1) screwed to a ceiling with a welded pipe section (2) which has an internal thread.

The threaded sleeve (3) welded to the pipe (4) is screwed into the pipe section (2).

The tube (4) has the same diameter as the smallest bicycle seat post on the market. For bicycles with a seat head sleeve with a larger inner diameter, a corresponding spacer sleeve (Figure B) is inserted before assembly. The folded edge of the spacer sleeve (Figure B) prevents

Slipping through the bicycle frame. ...7

After dismantling the respective seat post (by loosening a nut or a
Depending on the diameter of the seat head sleeve, the bicycle can be pushed onto the tube (4) with or without a spacer sleeve and secured in the same way as the seat post (quick release).

Since the tube (4) can be pushed deep into the frame of all bicycles, the working height can be easily varied. By slightly bending the tube (4) to approx. 15 degrees, the assembled bicycle is placed in a horizontal position.

Claims (6)

1. Bicycle maintenance bracket for securing bicycles so that all maintenance and care work can be carried out with both hands, characterized in that the mounting plate ( 1 ) with welded-on pipe section ( 2 ) which has an internal thread is screwed to the ceiling of a basement, hobby room or similar, wherein the seat head sleeve of a commercially available bicycle is pushed onto the pipe ( 4 ), which is previously screwed into the pipe section ( 2) with the welded-on threaded sleeve (3 ) , and is fastened in the same way as the previously dismantled seat post of the bicycle. 2. Bicycle maintenance holder according to protection claim 1, characterized in that the mounted bicycle is continuously adjustable in height according to the length of the tube ( 4 ). 3. Bicycle maintenance holder according to protection claim 1 or 2, characterized in that the mounted bicycle can be rotated continuously in both directions according to the number of threads of the threaded sleeve ( 3 ) screwed into the pipe section ( 2 ) and welded to the pipe ( 4 ). 4. Bicycle maintenance holder according to one of the protection claims 1 to 3, characterized in that the tube ( 4 ) angled by approximately 15 degrees enables the mounted bicycle to be in a horizontal position. 5. Bicycle maintenance holder according to one of the protection claims 1 to 4, characterized in that the tube ( 4 ) with welded threaded sleeve ( 3 ) can be unscrewed from the mounting plate ( 1 ) with welded pipe section ( 2 ), so that there is no risk of injury from a rod hanging in the room. 6. Bicycle maintenance holder according to one of the protection claims 1 to 5, characterized in that any commercially available bicycle can be pushed onto the tube ( 4 ) of the bicycle maintenance holder by inserting a corresponding spacer sleeve (Figure B) into the seat head sleeve.
