Description

[0001]

[0002]

[0003] The object of the present invention is therefore to provide an improved deflection device by means of which a desired resistance profile can be precisely generated in order to better meet the biomechanical requirements of fitness training.

[0004] This problem is solved by the features of claim 1, namely by a deflecting device of the type mentioned at the outset, in which at least one contour section is continuously adjustable and / or slidably mounted.

[0005] A first major advantage of the deflection device according to the invention is that it makes it possible to generate a desired resistance profile much more precisely than deflection devices from the state of the art.

[0006]

[0007] Axis of rotation has changed.

[0008] With an inventive deflection device, an individualized training effect can be generated for each trainee by individually adjusting at least one contour section. On the one hand, this increases the training effect by taking into account the fact that muscles are weaker or stronger at certain stretches, or that muscle strength decreases with fatigue.

[0010]

[0011] where the distance refers to an undisplaced state of the traction element.

[0012] The lever arm can also be a distance by which the at least one bolt of the traction element is deflected by the at least one contour section, the distance referring to the undeflected state of the at least one bolt.

[0013] In particularly preferred embodiments, the deflection device comprises a holder on which at least one contour section is continuously adjustable and / or slidably mounted.

[0014] Preferably, the base is attached to the bracket or the bracket encompasses the base.

[0015] The support may also be designed as a protective device or include a protective device, in particular to shield the deflection device and its interaction with the traction element from trainees.

[0016] Further advantageous embodiments of the invention are defined in the dependent claims.

[0017] It is particularly preferred that the base be designed as a pivot axis. This allows the deflection device to be used, for example, as a type of pulley or rope pulley.

[0018] In particularly preferred embodiments, the deflection device is rotatably mounted about the axis of rotation, wherein the at least one contour section is designed to deflect the traction element about the axis of rotation via the lever arm, wherein the at least one contour section is arranged at a distance from the axis of rotation and can be brought into different positions relative to the axis of rotation, wherein the at least one contour section is continuously adjustable and / or slidably mounted.

[0019] The axis of rotation can

[0020]

[0021] The training device must be equipped with at least one bearing for gentle storage.

[0022] It may be designed so that the base is fixed immovably to the training device. This means, in particular, that the deflection device as a unit can be attached to the training device in a non-slip manner, while at least one contour section is still adjustable and / or movable on the deflection device.

[0023] It is particularly intended that the least one control section Lt rsnnindest temporarily relatively nor base, especially rar rotation axis, can be fixed.1st.

[0024] It is also conceivable that at least one contour section is designed to change its position relative to the base, particularly to the axis of rotation, for example by being spring-mounted. In this way, for instance, a resistance profile can be created that depends, among other things, on the tensile force of the traction element.

[0025] The deflection device may be designed to have an anchor point for attaching one end of the pulling cord. This eliminates the need for an additional attachment point and any associated additional components on the training equipment.

[0026] It is conceivable that the position of the axis of rotation relative to at least one contour segment can be varied. Preferably, the relative position of the at least one contour segment can be further adjusted by means of an adjustable axis of rotation. This would further increase the adjustment options of the deflection device.

[0027] For example, the axis of rotation can be made adjustable by the fact that the deflection device has several possible prepared axes of rotation, of which one axis of rotation is actually used, e.g. connected to the training device, and around which the deflection device can then be rotated.

[0028] For example, the bracket can be designed with a variable axis of rotation.

[0029] In preferred embodiments, the at least one contour section comprises at least two contour sections which together form a contour for deflecting the traction element. This allows the resistance profile to be generated even more precisely.

[0030] Preferably, the contour comprises a multitude of contour sections, preferably spaced regularly apart from one another. This allows for the creation of a more uniform resistance profile.

[0031] In particularly preferred embodiments, the at least one contour segment, preferably the contour itself, lies in a plane, preferably one that is orthogonal to the axis of rotation. This generates a particularly simple and effective deflection device.

[0032] It is conceivable that several contour sections, preferably contours, arranged parallel to each other are provided, each of which is arranged in a plane.

[0033] In particular, it is conceivable that several contour sections, preferably K-, are arranged offset from each other along the axis of rotation.

[0034]

[0035] §

[0036] The resistance profile of sintered materials can be increased using a simple adjustment mechanism.

[0037] In particularly preferred embodiments, at least one contour segment is an endpoint of a slidably mounted and / or telescopically extendable element, in particular one that is mounted on the bracket. This allows, above all, the use of a simple mechanical adjustment mechanism.

[0038] For example, at least one element can be designed as a telescopic spindle and / or a telescopic rod, which can be fixed, for example, by means of a locking bolt. Examples include bed-raising fittings, locking fittings, or similar devices.

[0039] The deflection device can be designed so that at least one contour section is manually movable and / or adjustable. This eliminates the need for any additional energy.

[0040] Preferably, the deflection device is designed so that at least one contour section can be moved and / or adjusted mechanically, e.g., by motor and / or automatically. This allows for particularly rapid adjustment of the resistance profile.

[0041] In particularly preferred embodiments, the deflection device comprises at least one contact element designed to conform to the at least one contour section and / or to transmit a force generated by the traction element to the at least one contour section. This reduces or better distributes, for example, any point load on the traction element's surface. The contact element, which is preferably elastic, can fill any gaps in the contour between contour sections.

[0042]

[0043] In some embodiments, the traction element comprises at least one bar which is slidably mounted on the training device.

[0044] Preferably, at least one bar coincides with the first attachment point and / or the second attachment point on the training device.

[0045] A deflection device according to the invention can also be used in existing training equipment known in the prior art and can be retrofitted.

[0046] Furthermore, protection is sought for a method for operating a deflection device or a training device according to the invention, wherein the at least one contour section is brought into a desired position relative to the base and preferably fixed, so that a traction element is deflected by the deflection device.

[0047] Particularly preferably, at least one contour section is brought into a desired position relative to the axis of rotation and preferably fixed in order to generate a desired lever arm of the traction element around the axis of rotation.

[0048] In particularly preferred embodiments, the at least one contour section is moved from a first desired position to at least one further desired position, so that different resistance profiles can be generated successively.

[0049] Further advantages and details of advantageous variants of the invention will become apparent from the figures and the accompanying figure description. These show:

[0064] In this embodiment, the deflection device 1 is designed to be able to manually move and / or adjust at least one contour section 5.

[0065] Alternatively, at least one contour section 5 is designed to be movable and / or adjustable by machine, e.g. motorized and / or automatic.

[0072] In particular, the elements 10 and the directions 8, 9 are aligned centrally to the axis of rotation 4, so that the contour sections 5 are adjustable and / or displaceable radially to the axis of rotation 4, in particular telescopically copyable.

[0073] In Fig. 12, all elements 10 are in a medium state, with all contour sections 5 of the contour 7 forming a medium-sized circle. Symbolically, Fig. 12 also shows a contour 7 with the largest possible circle and a contour 7 with the smallest possible circle, representing states in which all elements 10, with the contour sections 5 arranged at their ends, are fully retracted and fully extended, respectively.

[0074] Fig. 13 shows three different states of the third embodiment of the inventive diaphragm steering device 1, showing that different positions of the contour sections 5 result in differently shaped contours 7.

[0076] Figures 14-16 show different views of a fourth embodiment of a deflection device 1 according to the invention. This differs from the third embodiment in particular in that it includes an attachment element 11.

[0077] In view of Fig. 14, it can be seen that the attachment element 11 is designed to conform to the contour sections 5.
