DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0058] FIGS. 1A and 1B show an exemplary embodiment of the jump height measuring device 1 according to the invention.

[0059] The jump height measuring device 1 forms a module with a base body 2 on which an arrangement of impact elements in the form of impact bars 3 is pivotably mounted. The identically formed impact bars 3 are arranged one above the other at identical distances from one another in the vertical direction on the base body 2.

[0060] The jump height measuring device 1 is mounted on a bracket, such as a post 4 standing on a ground, for example, such that the longitudinal axis of the base body 2 runs in the vertical direction. The longitudinal axes of the impact bars 3 runs in the horizontal direction, perpendicular to the longitudinal axis of the base body 2.

[0061] FIGS. 1A, 1B show the jump height measuring device 1 with the impact bars 3 in the base position, wherein the base position is the same for all impact bars 3, such that they are oriented in a vertical plane.

[0062] The jump height measuring device 1 is fitted to the bracket such that the impact bars 3 cover a jump height range. A person can train their jump behavior by jumping upward from the ground and impacting against the impact bars 2 with a hand, as indicated with the hand in FIGS. 1A, 1B. Depending on the jump height achieved, the person pivots a number of impact bars 3 with their hand. The pivoted impact bars 3 signal the jump height achieved by the person.

[0063] In the embodiment of the jump height measuring device 1, the impact bars 3 can be moved out of the base position into two end positions. In this context, the base position and the end positions are identical for all impact bars 3. In FIG. 2, the base position for an impact bar 3 is labeled with I. The two end positions are labeled with II and III.

[0064] To realize the pivot capability of the impact bars 3 between the base position and the end positions, a mounting arrangement is provided in the base body 2, said mounting arrangement having identical mounting units 5, wherein a mounting unit 5 is assigned to each impact bar 3. Such a mounting unit 5 with the assigned impact bar 3 is shown in FIG. 3.

[0065] Each mounting unit 5 has a mounting segment 6 that forms a pivot mount for the impact bars 3. Moreover, the mounting unit 5 has two stops 7a, 7b that limit the pivot movement of the impact bars 3 in the end positions.

[0066] As shown in FIG. 3, the mounting segment 6 has a rotationally asymmetrical cross- section with its essentially rectangular outer edges. The mounting segment 6 has one central segment and two outer segments that are connected by a crosspiece segment.

[0067] To this is adapted the free end of the impact bars 3 that is shown in FIG. 3. Said free end of the impact bars 3 is formed by two elastically deformable mirror-symmetrical arm segments 8a, 8b. The inner contours of the arm segments 8a, 8b are adapted to the outer contour of the mounting segment 6.

[0068] The outer sides of the two outer segments form contact surfaces 9a, 9b that are contacted by the inner sides of the arm segments 8a, 8b in the base position. The edges of the outer segments of the mounting segment 6 that adjoin the contact surfaces 9a, 9b are rounded.

[0069] The clear distance between the inner sides of the arm segments 8a, 8b in the non-deformed state is somewhat less than the distance between the contact surfaces 9a, 9b of the mounting segment 6.

[0070] In the base position (shown in FIGS. 4A and 4B), the inner sides lie in the contact surfaces 9a, 9b, wherein the arm segments 8a, 8b are elastically deformed and somewhat spread apart. A return force that holds the impact bars 3 in the base position is generated by the elastic deformation of the arm segments 8a, 8b.

[0071] If an impact is executed on the impact bars 3, they are pivoted against the return force and moved into an end position, wherein they then are in contact within a stop 7. In this end position, the mounting segment 6 lies in the recesses of the arm segments 8a, 8b without the arm segments 8a, 8b being elastically deformed (FIGS. 5A, 5B).

[0072] The impact bar 3 can be moved back to the base position by a reset device, or manually using a stick, or similar. Due to the shape of the mounting segment 6 that tapers toward the front, once the impact bar 3 is located in the vicinity of the base position, the base position is autonomously assumed.

[0073] FIGS. 6A, 6B show another exemplary embodiment for the jump height measuring device 1.

[0074] In this case as well, the impact bar 3 has two arm segments 8a, 8b that are pivotably mounted on a mounting segment 6, wherein again the inner contours of the arm segments 8a, 8b are adapted to the outer contour of the mounting segment 6. In the present case, the mounting segment 6 is circular-cylindrical in shape.

[0075] In the present case, the return force that holds the impact bars 3 in the base position is generated by a spring element in the form of a spring plate 10. The spring plate 10 is mounted with one end at the mounting unit 5 and with the other end in one of the arm segments 8a, 8b.

[0076] Due to this one-sided coupling of the spring plate 10 to an arm segment 8a, 8b, when the jump height measuring device 1 is used, each impact bar 3 is only pivoted in one direction. Accordingly, only one end position that is defined by the stop 7 is present.

[0077] FIGS. 7A, 7B show a variant of the embodiment according to FIGS. 6A, 6B. In this case as well, the return force for stabilizing the impact bar 3 in the base position is generated by means of a spring plate 10. The spring plate 10 is fixed to the outer side of an arm segment 8a, 8b. Due to the one-sided coupling of the spring plate 10 to an arm segment 8a, 8b, again the impact bar 3 can only be pivoted in one direction up to a stop 7′.
