Description

[0001] The present invention relates to a device for sports and / or games, in particular a sports and / or games device for practicing roller sports activities.

[0002] Roller sports such as roller hockey and figure skating evolved from sports originally practiced only in winter, such as ice hockey and figure skating. Appropriate training equipment, such as roller skates and inline skates, has been developed for these summer-oriented roller sports. These training devices enjoy widespread popularity not only in sports but also in games.

[0003] In addition, summer training equipment has also been developed for the classic winter sport of cross-country skiing. Roller skis and roller skis exist, as disclosed, for example, in DE 198 394 17 A1 or DE 20 2015 105 891 U1.

[0004] Many sports and play equipment for roller sports require a surface that is as smooth as possible, especially paved, for movement. Use on planted areas, such as lawns, would result in the plants wrapping around the rollers. Use on rocky ground is also not possible, as there is a high risk of falling. The same applies to surfaces contaminated with leaves, branches, or similar debris. Manhole covers or bitumen embedded in the road surface also pose a fall hazard.

[0005] It is an object of the present invention to provide a device for sports and / or games, in particular a sports and / or games device for practicing roller sports activities, with which it is possible to move safely even on uneven surfaces, such as grass or stony ground.

[0006] The object is achieved according to the invention by a device for sport and / or play, comprising a housing, a chassis and a binding device, wherein the chassis has at least two rollers arranged one behind the other, each with a rotational axis and a closed band, the rotational axes of the at least two rollers are aligned parallel to each other and the closed band comprises the at least two rollers, wherein the at least two rollers are arranged at least partially in the housing and are each rotatably mounted and wherein the housing has an upper side and the

[0007] Binding device is attached to the top of the housing.

[0008] A binding device is understood here as a device that allows a secure connection to be established between the user and the device for sports and / or play. In an exemplary binding device, the binding device may have a receptacle into which a user's shoe can be fastened. Alternatively, the binding device may already have a shoe into which the user can slip their foot.

[0009] Preferably, the closed belt spans the at least two rollers in a close fitting manner, and the at least two rollers function as track rollers and usually have a cylindrical basic shape with a running surface. In this arrangement, the belt spanning the track rollers is driven, whereby the belt spanning the track rollers in turn drives the track rollers. The track rollers are therefore free-running and not self-driven. The spanning belt is driven, for example, by a deliberate sliding movement of the user. The rollers can be rotated in two directions, so that movement of the belt is possible in a clockwise and counterclockwise direction. This allows a user to move forwards and backwards.

[0010] The invention is based on the idea of ​​providing a sports or play device which, like a tracked or caterpillar vehicle, is provided with a chain or a belt and rollers.

[0011] The provision of a running gear comprising a circulating belt with rollers rotating within it has the advantage over the use of simple wheels in that the chassis is all-terrain and offers good tracking. Sports or play equipment equipped in this way can therefore be used even on uneven surfaces, while simultaneously minimizing the risk of falls.

[0012] It is advantageous that the at least two rollers have the same diameter, so that a flat surface is formed both on the upper side of the chassis, where the binding device is located, and on the underside of the chassis, which rests on the ground. This increases the stability of the chassis and thus the stability of the sports and / or play equipment, and also the smooth running of the chassis, since the at least two rollers can be rotated at the same angular speed by means of the driven belt.

[0013] In a preferred embodiment, a plurality of rollers arranged one behind the other are provided, each having a rotational axis, with the rotational axes aligned parallel to one another, and the belt encompasses the plurality of rollers arranged one behind the other. Here, too, it is particularly advantageous for the belt to tightly encompass the plurality of rollers arranged one behind the other. The more rollers provided, the greater the stability, stability, and tracking of the device for sports and / or games.

[0014] Preferably, the individual rollers of the numerous rollers arranged one behind the other have the same diameter, so that the underside and top of the chassis are flat. This also allows for gliding and makes it possible to achieve characteristics comparable to classic cross-country skis on non-snow-covered surfaces.

[0015] It is preferably provided that the plurality of rollers is arranged in multiple rows, preferably in two rows, with at least two rollers being mounted one behind the other in each row.

[0016] It is advantageous if a stabilizing roller is provided between two adjacent rollers. The stabilizing roller has an axis of rotation that is aligned parallel to the axis of rotation of the at least two rollers, wherein the diameter of the stabilizing roller is smaller than the diameter of the two adjacent rollers. The axis of rotation of the stabilizing roller can lie outside, in particular below, a plane spanned by the two axes of rotation of the two adjacent rollers. If more than two adjacent rollers are present in the chassis, several stabilizing rollers can also be provided, each arranged between two adjacent rollers. In particular, when more than two rollers arranged one behind the other are provided, the stabilizing roller ensures that the device for sports and / or games has good off-road capability and a stable stand.

[0017] In a preferred embodiment, one or all of the wheels of the chassis are spring-mounted. However, particularly when using the device for sports and / or games on uneven surfaces, this can lead to unwanted vibrations of the chassis wheels. To prevent unwanted vibrations on uneven surfaces, it is particularly advantageous to provide a shock absorber on at least one wheel or to provide a common shock absorber for all wheels of the chassis. This allows the user to move more comfortably on uneven surfaces.

[0018] In the event that the device for sports and / or games is intended to move only forward, as in classic cross-country skiing, and reverse movement of the device for sports and / or games is not desired, a backstop is preferably provided. The backstop ensures that the at least two rollers rotate only in one direction, namely forward.

[0019] As stated above, in a preferred embodiment, the belt is provided so that it fits tightly against the at least two rollers. As the belt is driven, the at least two rollers are also driven. In the event that the closed, circulating belt is applied to the rollers with excessive or insufficient tension, it is advantageous to provide a tensioning device for the closed belt. In a preferred embodiment of a tensioning device, the position of at least one roller is horizontally adjustable.

[0020] If the at least two rollers are each essentially cylinder-like with a flat running surface, there is a risk that the belt will shift in the axial direction of the rollers. To prevent the belt from sliding off the rollers laterally, i.e. in the axial direction of the rollers, it is advantageous for at least one roller, in particular a cylinder-like roller, to be provided with an edge at each of its ends, which extends along the circumference of the roller and points radially outwards. The height of the edge is dimensioned such that the belt is guided between the edges, but projects beyond the edge in the radial direction of the roller, whereby the belt can still rest on the ground.

[0021] The edge can be part of the running surface, so that a groove is created on the running surface of at least one roller in which the belt can be guided.

[0022] Alternatively, the rim can be formed by a disc attached to the end of the roller and having a diameter larger than that of the roller.

[0023] In a further development in which a plurality of rollers is provided, it is advantageous that the plurality of rollers are provided with edges, whereby the height of the edge for all rollers should be selected such that the edge does not protrude beyond the belt in the radial direction of the roller.

[0024] In a preferred embodiment, the binding device is rigidly connected to the housing. This makes it possible to use the device for sports and / or play, similar to downhill skis on unsnowy slopes.

[0025] To use the device for sports and / or play in the sense of cross-country skiing, it is advantageous for the binding device to be pivotally attached to the top of the housing by means of a pivoting device, such as a joint connection. Preferably, the pivot axis of the pivoting device is aligned parallel to the rotational axis of the wheels, with the pivoting device being provided at the front in the running direction and thus in the front section of the housing.

[0026] Additionally, a locking element can be provided for the binding device, so that the binding device is immovably connected to the housing. The locking element is preferably located at the rear in the direction of travel and thus in the rear section of the housing. In this embodiment, the device can be used flexibly for sports and / or play. For example, the device can be used for sports and / or play both as a classic cross-country ski and as a classic downhill ski on a non-snowy surface.

[0027] In order to limit the deflection movement of the foot relative to the device for sports and / or games in the case where the binding device is pivotally attached to the top of the housing, it is advantageous that a stroke limiting element is provided between the housing and the binding device.

[0028] In a preferred embodiment, the binding device comprises a binding plate, wherein the binding plate is pivotally mounted on the top of the housing. Particularly for use of the device for sports and / or games such as cross-country skiing, it is advantageous that a pivoting device is provided for pivotally mounting the binding plate on the top of the housing. The pivoting axis of the pivoting device is aligned parallel to the rotational axis of the rollers. In particular, the pivoting device is located at the front in the running direction and thus in the front section of the housing.

[0029] The binding plate ensures that the user has a stable stance on the chassis or chassis.

[0030] To control the speed when using the device for sports and / or games, it is advantageous to provide a braking device. For example, the braking device can be mechanically actuated and comprise a brake lever, brake shoes, and a tension element that interact with at least one roller. The tension element can be a cable or Bowden cable. This pulls a brake lever upward, causing brake shoes to decelerate the rollers. Alternatively, the braking device can be electronically actuated and, in particular, remotely controlled.

[0031] In a preferred embodiment, the closed belt is a rubber chain, so that the device for sports and / or games does not leave any damage to the surface on which the device for sports and / or games is used.

[0032] Preferred embodiments are explained in more detail with reference to the accompanying drawings, in which: Fig. 1 a side view of the device for sports and / or games, Fig. 2 the chassis of the device for sports and / or games, Fig. 3 a braking device of the device for sports and / or games and Fig. 4 a cross section through the device for sports and / or games.

[0033] Fig. 1 shows a device for sports and / or games 10, comprising a housing 12, a chassis 14 with five similar rollers 16 and a closed belt 18 in the form of a rubber chain and a binding device 20. The housing 12 has a top 22 and two sides 24, so that the housing 12 has a U-shaped cross section (see Fig. 4 ). The housing 12 is open at its end faces, but can also be closed.

[0034] The five rollers 16 arranged one behind the other have a cylindrical basic shape with a running surface and each have a rotational axis 26, wherein the rotational axes 26 of the rollers 16 are aligned parallel to each other. The closed belt 16 tightly encompasses the five rollers 16 arranged one behind the other. Each roller 16 has a physical axis in the form of a pin 27 (see Fig. 4 ). The five rollers 16 and the belt 18 are thus part of the chassis 14 in the form of a track chain or caterpillar (see Fig. 2 ).

[0035] As particularly in Fig. 2As can be seen, a stabilizing roller 28 is provided between each two adjacent rollers 16, the diameter of the stabilizing roller 28 being smaller than the diameter of the two adjacent rollers 16. The stabilizing rollers 28 each have an axis of rotation 30, the axis of rotation 30 of the stabilizing rollers 28 being arranged below the axes of rotation 26 of the rollers 16 and being aligned parallel to the axes of rotation 26 of the rollers 16.

[0036] The housing 12 has 24 vertically aligned recesses 32 on both sides, through which the pins 27 of the rollers 16 engage. The rollers 16 are arranged at least partially in the housing 12 and are rotatably mounted on the housing 12. The recesses 32 are designed as slots open at the bottom, so that the housing 12 can be inserted from above over the pins 27 of the rollers 16.

[0037] Although not shown, corresponding bearings such as ball bearings are provided on the pins 27, on which the housing 12 rests, so that the pins 27 can rotate with little friction.

[0038] One of the recesses 32 on the housing 12 comprises a horizontal slot-like opening 34. The slot-like opening 34 is part of a tensioning device for the belt 18. With the help of the slot-like opening 34, the distance between two adjacent rollers 16 can be changed, whereby the belt tension of the belt 18 can be adjusted.

[0039] Furthermore, a braking device 36 is provided. The braking device 36 comprises a brake lever 38 and brake shoes 40. The brake shoes 40 are located inside the housing 12 and interact with the running surfaces of the rollers 16. The brake lever 38 is positioned on the outside of the side wall 24 of the housing 12. The brake shoes 40 and the brake lever 38 are connected to one another, with the brake shoes 40 being pivotally mounted about a rotation axis 41. Although not shown, the braking device 36 comprises a tension element, for example a cable, so that the brake lever 38 can be actuated by means of a cable pull.

[0040] The binding 20 is located on the top side 22 of the housing 12 and comprises a binding plate 42 and shoe holding elements in the form of straps 44.

[0041] The binding plate 42 is, for example, a metal or plastic plate. The binding plate 42 has a front side, which, in the operating state, is where the user's toes are located. The front side of the binding plate 42 is pivotally connected to the housing 12 by means of a hinge 46.

[0042] A lifting height limiter 48 is provided at the end of the binding plate 42 facing the heel. The lifting height limiter 48 is a joint with two articulated arms 49, with the free ends of the articulated arms 49 being attached in the heel area of ​​the binding plate 42, on the one hand, to the binding plate 42 and, on the other hand, to the upper side 22 of the housing 12.

[0043] In addition, a locking device 50 is located on the top side 22 of the housing in order to firmly connect the binding plate 42 to the housing 12 if necessary.

[0044] To use the sports and / or game device 10, the user inserts their foot, which is in a shoe 52, into the straps 44. Once the shoe 52 is firmly connected to the straps 44, the chassis 14 of the sports and / or game device 10 can be operated using muscle power. The user drives the belt 18, causing the rollers 16 located within the belt 18 to rotate.

[0045] In steep terrain, the binding plate 42 of the binding 20 is fastened in the locking device 50 so that the device for sports and / or games 10 can be used, for example, like a downhill ski.

[0046] On less steep terrain, the locking device 50 can be released, allowing the device 10 to be used for sports and / or play, similar to a cross-country ski. The lifting height limiter 48 ensures that the angle between the binding plate 42 and the housing 12 does not exceed a maximum value.

[0047] To slow down the sports and / or game device 10 when necessary, it is possible to actuate the brake lever 38 using a user-operable cable, so that the brake shoes 40 decelerate the rollers 16. Although not shown, the braking device can also be actuated electronically. In this case, a remote control is provided, in particular, to actuate the brake shoes.

[0048] Although not shown, the sports and / or play device 10 may include a roller 16 with a reverse lock to prevent the sports and / or play device 10 from accidentally moving backward. This is advantageous for a classic cross-country skiing style application.

[0049] The rollers 16 shown in the figures are cylindrical with a continuous, flat running surface. Alternatively, although not shown, a radially oriented circumferential edge can be provided at each end of the roller, so that the running surface has a groove in which the rotating belt is guided. The height of the edge is less than the thickness of the belt.

[0050] In embodiments not shown, more or fewer rollers may be provided.

[0051] In an embodiment not shown, the rollers 16 of the chassis 14 are spring-mounted. One or all of the rollers can have a shock absorber. Alternatively, a common shock absorber can be provided for all rollers.

[0052] The binding shape is only an example. There are many ways to attach a boot or foot to a binding plate. For example, a boot can be connected directly to the binding plate.

[0053] Likewise, the binding plate can be directly, in the sense of rigidly, connected to the housing.

[0054] The present invention also includes embodiments not shown, in which individual features of the illustrated embodiments have been omitted or in which features of different embodiments are combined.
