Training hurdle

The invention relates to a training hurdle which is particularly suitable for children and young people who want to learn and practice the basic techniques of hurdling.

Training hurdles are already known that have two vertical supports arranged on the sides, between which a horizontal bar is provided. This bar is clipped into lateral support elements, each of which is attached to the vertical supports using a screw. To adjust the height of the bar, the screws must be loosened, the support elements moved up or down and then the screws tightened again. This procedure is cumbersome.

Furthermore, the vertical supports arranged on the sides of the well-known training hurdles extend far beyond the horizontal bar between them. This has the disadvantage that children and young people running or jumping over the bar during training can hit the supports with their arms and thereby knock over the entire hurdle.

Based on this prior art, the invention is based on the object of specifying a new training hurdle which is improved with respect to the disadvantages of known training hurdles described above.

This object is achieved by a training hurdle having the features specified in claim 1. Advantageous

&diams; « . I

Embodiments and developments of the invention emerge from the dependent claims.

The advantages of the invention are in particular that the bar running between the supports forms the upper end of the training hurdle. This ensures that trainees do not accidentally hit the side supports with their arms when running over or jumping over the hurdle and knock them over. Furthermore, adjusting the height of the hurdle is simplified. Such a height adjustment can be carried out advantageously by simply pressing on the pull-out part or pulling the pull-out part out of the respective tube. No tools are required and no screws need to be loosened or tightened.

Further advantageous properties of the invention will become apparent from its exemplary explanation with reference to the figures.

It shows:

Figure 2 is a sketch of the lower end region of an extension part of the training hurdle shown in Figure 1.

Figure 1 shows a sketch of a training hurdle according to the invention. The hurdle shown has two laterally arranged supports 1, 2. Between these supports there is a horizontally running bar 3 provided with a plastic or foam coating 3a, the end areas of which are connected to the supports. The side supports shown each have a base part 18, 19. Furthermore, they are each provided with a vertically running square tube 4, 5, within which a pull-out part 6, 7

is mounted in a height-adjustable manner. A receiving unit 8, 9 for the rod 3 is provided on the upper side of the respective extension part.

The rod 3 is preferably a round rod and is made of wood or plastic. It is preferably surrounded by a plastic or foam casing 3a in its area between the receiving units 8 and 9.

The receiving elements 8, 9 are tubular and are designed to receive the end areas of the rod 3. The end areas of the rod are fixed in the receiving elements

' units is carried out using one screw Sl, S2 each.

The vertically running square tubes of the side supports are connected to the base part 18, 19 on their underside as well as on their front and back sides via a weld seam. The base part runs in a direction perpendicular to the rod and has a round cross-sectional area. The base part also has a first area which runs in front of the square tube 4, 5 as seen in the running direction &khgr; and a second area which runs behind the square tube 4, 5 as seen in the running direction &khgr;. Both of the aforementioned areas each have a first section resting on the floor and a second section which is curved upwards and which is welded to the respective square tube in its end area.

The vertically running square tubes 4, 5 are each provided with holes L on their inner and outer sides, which serve to accommodate locking elements. Each of the square tubes mentioned has holes at different heights, whereby each of the square tubes has two holes arranged at the same height, whereby one of these holes is on the side of the hurdle facing the other square tube and the other hole is on the

from the side of the hurdle facing away from the other pipe.

Figure 2 shows a sketch of the lower end area of an extension part of the training hurdle shown in Figure 1. From Figure 2 it can be seen that the locking elements, which come to rest at a desired height in the holes of the square tubes 4, 5, are spring-loaded balls 10, 11. Each of the extension parts 6, 7 has two spring-loaded balls, one of which is provided on the side of the hurdle facing the other support and the other on the side facing away from the other support.

The spring-loaded balls 10, 11 are held in a cup-shaped bearing 12, 13, which is arranged in a through hole 14 of the respective extension part. This through hole 14 is located in the area of the lower end of the respective extension part. The respective cup-shaped bearing 12, 13 is provided with a flared edge 15, 16 in its outward-facing end areas.

A reduction in the height of the side supports 6, 7 of the hurdle shown in Figure 1 can be carried out in a simple manner by pressing the respective pull-out part downwards by hand. When this downward pressure is applied, the balls 10, 11 are pressed inwards against the force of the respective spring, so that the pull-out part can be moved downwards within the square tube. When the balls reach the next lower holes in the square tube during this pressure, the balls are pressed outwards into these holes by the force of the spring and are thus fixed in a lower position. From there, a further reduction in the height of the side supports can be carried out if necessary.

&bull; · t» i

If, however, the height of the hurdle and thus of the side supports is to be increased, the extension parts 6, 7 are pulled up by hand from the square tubes 4, 5. During this pulling, the balls 10, 11 are also pressed inwards against the force of the respective spring so that the extension part can be pulled up. If the balls then reach the next, higher holes in the square tubes during this pulling out, they are pressed into these holes by the force of the relaxing spring so that the respective extension part is fixed in a higher position than before. From there, the extension parts can then be pulled out of the square tubes further to raise the hurdle even further.

A hurdle according to the invention is therefore characterized in that, on the one hand, the lateral supports do not extend beyond the transverse bar 3 in terms of their height and that the height of the hurdle can be changed manually without it being necessary to loosen a screw and subsequently tighten the screw.

The side supports including the respective base section are preferably made of powder-coated aluminum. The balls 10, 11 and the springs acting on them are preferably stainless steel components. The cup-shaped bearings 12, 13 are preferably made of plastic or also of stainless steel.
30

For example, the distances of the holes L from the ground and the distances of the holes from each other are chosen so that the height of the training hurdle can be set to 3 0 cm, 3 5 cm, 40 cm, 45 cm or 50 cm.
35

Training hurdles according to the invention can be used not only for training hurdle running, but

·

for example during sprint training and also during training in other sports.

Furthermore, a training hurdle according to the invention can be disassembled quickly and easily and can be stored in an equipment cabinet to save space.

The length of the wooden stick 3 and thus the width of the hurdle

is preferably chosen so that it corresponds approximately to the width of a

an athletics career, i.e. in the area

from 90 - 100 cm.
