Description:

The solution according to the invention and the use of the holding device are explained in more detail using illustrations, showing:

Figure 1: a side view in section

Figure 2: a top view of the holding device

Figure 3: a schematic diagram of the dampening process

Fig. 1 shows the side view of the technical basic structure of the holding device in section. The center of the clamping element (K) is at a height of 120 cm, measured from the ground. The restraint barrier (B) is at ground level at a defined distance (A) measured from the center of the clamping element (K). The restraint barrier (B) prevents the rear wheel (H) from rolling back. The position of the restraint barrier is chosen so that the largest possible commercially available bicycle in an upright position cannot roll over backwards on its longitudinal axis. The largest permissible angle is 60° measured from the horizontal.

The usable clamping area (NH) for the front wheel (V) is designed so that bicycles of different sizes in length and height can be inserted with the respective angle of inclination.

Fig. 2 shows the holding device viewed from above. The example shows supporting walls (T1 and T2) that converge at an angle of 45°. Other arrangements of the supporting walls are possible without any problem.

The hard rubber pads (P1 and P2) are attached to the center. The gap depth (ST) of the hard rubber pads (P1 and P2) is designed so that standard bicycles with their front wheel (V) can be accommodated in them; the front wheel (V) can penetrate the wedge-shaped gap opening (S) with its defined gap depth (ST) into the gap (S) up to the middle of the wheel. The clamping effect of the hard rubber pads (P1 and P2) prevents the bicycle from tipping sideways.

A radial retaining barrier (B) at a distance (A) from the clamping element (K) blocks the rear wheel (H) and prevents it from rolling away from the parking position.

Continued Description

Fig. 3 shows the operating sequence.

To put any bicycle into its parking position, the bicycle (F) must be brought into the starting position (position 1).

The bicycle (F) is then lifted at the front wheel (position 2) and at the same time the rear wheel is positioned over the barrier (B) towards the holding device.
The front wheel is pushed into the clamping device (K) and held in the final position (parking position) by its clamping effect. The retaining barrier (B) in front of the rear wheel prevents the upright bicycle (F) from rolling away.

Claims (1)

QUADRA Product Design GmbH ·· · . .**..**. ."..·· Protection claim : Device for holding bicycles in an upright parking position, characterized in that a clamping element (K) in conjunction with a retaining bar (B) fixes any bicycle (F) at the front wheel (V) and secures the rear wheel (H) of the upright bicycle against rolling away. The clamping element (K) is located at a height of approx. 120 cm from the ground. It consists of two symmetrical hard rubber pads (P1 and P2), which are attached to the right and left of a supporting wall (T1 and T2). The arrangement results in a wedge-shaped gap (S). The selected opening width ensures that the front wheel fork or front wheel hub of any standard front wheel (V) can be accommodated. Due to the flexibility of the hard rubber pads (P1 and P2) in conjunction with the wedge-shaped gap (S), a clamping effect is achieved. The gap depth (ST) between the two hard rubber pads (P1 and P2) allows a front wheel (V) to be immersed above the front wheel hub and prevents the bicycle from tipping sideways (F). The distance (A) between the retaining bar (B) and the clamping element (K) as well as its vertical clamping height (SH) allow bicycles with different frame lengths to be positioned upright. The only thing that changes is the angle of inclination of the respective bicycle.
