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 DE198 394 17 A1 or DE 20 2015 105 891 U1.

[0004] Furthermore, EP3815757 A1 discloses a downhill ski having a track device so that this downhill ski can be used even when there is no snow.

[0005] A training device that enables movement comparable to that of ice skating on a street surface, even without an ice surface, is described in JP 09019529.

[0006] Finally, EP0904809 B1 discloses a pivotable connecting device which can be used in a variety of sports equipment which are attached to the foot of a user, such as skis, roller skates or shoes for ice skating, in order to increase the performance of the user.

[0007] 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.

[0008] 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 sports activities in the sense of a cross-country ski, with which it is possible to move safely even on uneven surfaces, such as grass or stony ground.

[0009] The object is achieved according to the invention by a device for sport and / or play suitable for use in the sense of a cross-country ski on non-snow-covered ground, comprising a housing, a running gear and a binding device, wherein the running gear 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 one another and the closed band comprises the at least two rollers, wherein the at least two rollers are arranged at least in sections in the housing and are each rotatably mounted and wherein the housing has an upper side and the binding device is pivotally fastened to the upper side of the housing.

[0010] 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.

[0011] The invention is based on the idea of ​​providing a piece of sports or play equipment suitable for use as a cross-country ski on unsnowy surfaces, which is equipped with a track or chain and rollers, similar to a tracked or caterpillar vehicle. The provision of a chassis comprising a rotating belt with rotating rollers has the advantage over the use of simple wheels in that the chassis is suitable for all-terrain use and has good tracking. The sports or play equipment equipped in this way can thus also be used on uneven surfaces, while simultaneously minimizing the risk of falling.

[0012] 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 each other. The more rollers provided, the greater the stability, stability, and tracking of the device for sports and / or play. This also makes it possible to achieve riding characteristics comparable to classic cross-country skis on non-snow-covered surfaces.

[0013] 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.

[0014] It is advantageous to provide a stabilizing roller between two adjacent rollers. The stabilizing roller has a rotational axis aligned parallel to the rotational axis of the at least two rollers. Particularly when more than two rollers are arranged one behind the other, the stabilizing roller ensures that the device for sports and / or play has good off-road capability and a stable footing.

[0015] In the event that the sports and / or games device is intended to move only forwards and reverse movement of the sports and / or games device is not desired, a backstop is preferably provided. The backstop ensures that the at least two rollers rotate only in one direction, namely forwards.

[0016] 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 too much or too little 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.

[0017] Additionally, a locking element can be provided for the binding device, so that the binding device is immovably connected to 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 unsnowy surfaces.

[0018] 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.

[0019] In a preferred embodiment, the binding device comprises a binding plate, which is pivotally mounted on the top of the housing. This ensures stable positioning of the user on the housing or chassis.

[0020] 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 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.

[0021] 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.

[0022] 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.

[0023] 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 front ends.

[0024] The five rollers 16 arranged one behind the other 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).

[0025] As particularly in Fig. As can be seen in Figure 2, a stabilizing roller 28 is provided between each two adjacent rollers 26. The stabilizing rollers 28 each have a rotation axis 30, wherein the rotation axis 30 of the stabilizing rollers 28 is aligned parallel to the rotation axes 26 of the rollers 16.

[0026] Vertically aligned recesses 32 are provided in the housing 12, 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] In order to brake the device for sports and / or games 10 when necessary, it is possible to actuate the brake lever 38 by means of a cable actuated by the user, so that the brake shoes 40 brake the rollers 16.

[0037] Although not shown, the sports and / or game device 10 may include a roller 16 with a non-reverse mechanism to prevent the sports and / or game device 10 from accidentally moving rearward.

[0038] In embodiments not shown, more or fewer rollers may be provided.

[0039] 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. QUOTES CONTAINED IN THE DESCRIPTION
