PATENT APPLICATION

Device for sliding on slippery surfaces

description

The present invention relates to a device for sliding on slidable surfaces, in particular on snow, water or earth.

Surfboards are known which are used for sliding on water, and so-called snowboards which are used for sliding on snow are known. However, both devices are used by the user in an upright posture. In addition, sleds are known which consist of a plastic molded shell (plastic sled) and which are mainly used by children as a sled replacement. These types of plastic sledges are kept in a shape and size that makes them unsuitable for growing children or adolescents. These well-known plastic sledges are also very simple and offer no user comfort. They do not offer directional stability when gliding on snow or water.

German Offenlegungsschrift DE 23 22 211 describes a sports device for use on snow or in water, which has approximately the shape of a disc-like or elongated floating disc, on the underside of which runners and on the top of which are provided seating or lying surfaces. This sports device consists of two closely connected shells, the cavity formed by the shells being filled with a plastic with closed cells. This makes the sports equipment buoyant.

This well-known sports device also has a limited area of application, offers little user comfort and, due to its disc-shaped shape, hardly guarantees any directional stability when gliding. The invention has for its object to provide a device of the type mentioned above, which is suitable for sliding on a wide variety of surfaces, offers a high level of user comfort with high dimensional stability and behaves directionally stable when sliding. In addition, the device should be suitable for children and adolescents as well as for adults.

This is achieved according to the invention in that the device has a dimensionally stable sliding shell with an underside forming a sliding surface and in that the sliding shell is provided with an elastic support firmly connected to it on its upper side.

The device according to the invention has the great advantage that it develops buoyancy due to the materials selected, that is to say it floats, and has extraordinarily good sliding properties on water, snow, ground or grass surfaces. In addition, it glides over wavy, bumpy and uneven surfaces, whereby the elastic pad mitigates unpleasant bumps and knocks. With the device according to the invention, it is even possible to jump over smaller hills and thereby achieve considerable distances. Its wide range of applications is also advantageous because it can be used by children and adolescents as well as adults in a lying, sitting, kneeling or standing posture.

Advantageous further developments result from the subclaims. The length of the device can be a multiple of its width, which favors manageability by allowing the user to lie, sit, kneel or stand comfortably on the device.

A particular comfort when using the device can be given in that the thickness of the support is a multiple of the thickness of the sliding shell. This cushion-like pad reliably absorbs shocks and bumps when sliding over uneven surfaces. In addition, at the points where the user lies, sits, kneels or stands, the support is pressed in in such a way that there are recesses which provide the user with a secure hold on the device. As a result, the device according to the invention is advantageously adapted to the physique of the respective user, so that it can be used by both children and adolescents can also be used comfortably by adults. This pillow-like support can be made of any elastic material, for example foam, air cushions, etc.

A quick and safe sliding can in particular also be ensured in that the sliding shell has an arched front wall and raised side walls. This design enables obstacles and unevenness to be handled particularly well by the device, the device remaining dimensionally stable.

In a further preferred embodiment, the support extends between the arched front wall, the raised side walls and the rear end of the sliding shell. This training gives the device a particularly compact body shape.

In a further advantageous embodiment, the side walls are provided with an elevation in the central region of the sliding shell. The increase can extend across the entire width of the sliding shell. This training gives the device a particularly high stability, especially in its middle area, so that it can also be used by heavy people without impairing its excellent sliding properties and its dimensional stability.

Furthermore, a bearing point for receiving a manually operable, preferably removable, and / or pivotable brake lever can be arranged in the area of the elevation in the side walls. Specifically, the brake lever can be a two-armed lever, one lever arm of which is designed as a handle and the other of which is designed as a braking element.

With the independently operated brake levers, the device can be steered particularly well and brought to a standstill. This ensures a comfortable directional orientation while gliding and even more reliable handling of the device.

A further advantageous embodiment according to the invention for steering the device consists in the fact that the sliding shell on its underside forming the sliding surface at least in the area its rear end is provided with one or more guide runners. Alternatively, it is also possible to provide the sliding shell with one or more guide grooves on its underside forming the sliding surface, at least in the area of its rear end.

To achieve a particularly high lubricity and dimensional stability, the sliding shell consists of a wear-resistant, slidable hard plastic, preferably a polyacrylate. It is also conceivable that the sliding shell consists of a material that has a mixture or a layer structure made of glass, ceramic, plastic and / or metal. An excellent alternative is to manufacture the sliding shell from a material that is formed from nanoparticles.

The support can advantageously consist of a polyurethane or an EVA plastic. It is extremely useful to provide the pad with an anti-slip surface layer. Such training significantly increases the stability of the user on the device.

Finally, a comfortable and safe handling of the device can also be achieved in that at least one holding means is provided in the area of the front wall of the sliding shell. The at least one holding means can be a hanger, a band, a cord or the like, which the user of the device can hold on to in a lying, kneeling, sitting or standing posture.

In a further advantageous embodiment according to the invention, the side walls and the front wall of the sliding shell form a U-shaped peripheral frame. This design of the sliding shell gives the device an extremely high torsional stiffness and thus better stability, which results in safe steering properties.

Furthermore, between the guide runners, concavely shaped guide grooves can be provided, which extend over half the length of the device, each guide runners tapering in a wedge shape in the sliding direction of the device. In an advantageous development, the guide grooves can extend approximately up to half the length of the device and in their width from guide skid to guide skid. The end faces of the guide grooves facing the front wall can rise to the underside of the sliding shell.

This advantageous design of the sliding shell also serves for better and safer guidance and steering of the device.

Finally, convenient and safe handling of the device can also be improved in that the two opposite longitudinal edge regions of the underside of the sliding shell each have an inclined surface which extends at an acute angle from the underside to the respective side wall.

This training enables the user to safely steer the device through sensitive and skillful body movements.

In detail, the inclined surfaces can be arranged at an angle of 5 ° to 20 °, preferably 10 °, to the plane of the sliding surface. The inclined surfaces in the sliding direction of the device can extend approximately to the beginning of the arched front wall, starting broadly at the rear end of the sliding shell and tapering to the area of the front wall.

The further features and advantages can be found in the description of exemplary embodiments of the invention illustrated in the following drawings. Show it:

As shown in FIG. 1, the device 10 according to the invention consists of an essentially rectangular, dimensionally stable sliding shell 11 with a front wall 12 raised in an arcuate manner in its front area and laterally raised side walls 13. On its underside 14 forming a sliding surface are in the area of the rear End 19 of the sliding shell 1 1 formed three keel-like runners 15, which serve to give direction and control of the device 10 while sliding. The sliding shell 1 1 consists of a wear-resistant n hard plastic, such as polyacrylic, or a mixture of glass, ceramic, plastic and / or metal. The sliding shell 11 can also consist of a material which is formed from nanoparticles.

On the top of the sliding shell 1 1, an elastic, almost flat support 17 is applied, which is firmly connected to the sliding shell 1 1, for example directly foamed or glued to the sliding shell 1 1 and has a thick, cushion-like height. Edition 17 extends between the raised front wall 12, the raised side walls 13 and the rear end 19 over the entire surface of the device 10.

The pad 17 consists for example of a PU foam or an EVA foam. The surface of the pad 17 is provided with an anti-slip surface 18, which can be applied directly to the pad 17, for example with a spray adhesive. The non-slip surface of the device 10 designed in this way significantly increases the lying, sitting, knee and standing safety of the user of the device 10.

In the central area, the sliding shell 11 has an elevation 16. In the area of the elevation 16, starting from the outer surfaces of the side walls 13, bearing points 29 in the form of threaded bores 20 are introduced transversely to the longitudinal direction of the device 10, in each of which a threaded bearing bush 21 is seated. A bearing journal 22 is screwed into each of the threaded bearing bushes 21, and a brake lever 30 in the form of a two-armed lever 24 is pivotably mounted on the end 23 projecting into the open. The brake lever 30 has a lever arm designed as a handle 25 and as a brake element 26. Each of the two-armed levers 24 is held on the bearing pin 22 in a pivotable manner by means of locking washers 27. However, both levers 24 can be removed from the device 10 at any time, for example when using the device in water instead of in snow. This two-armed lever 24 serves both to steer the device 10 during the sliding phase and to brake in order to bring the device 10 to a standstill.

The extending transversely to the longitudinal extension of the device 10 increase 16 also serves to stabilize and improve the ^'strength of the device 10, so that even a user with a high body weight, the device can use 10 without the sliding properties and the dimensional stability of the apparatus 10 affects are.

In Figure 4, the guide runners 15 shown in Figures 1 and 3 are shown in cross section. These guide runners 15 provided in the area of the rear end 19 of the device 10 on its underside 14 are triangular in cross section. However, the guide runners 15 can also have any other suitable cross-sectional shape, such as trapezoidal, semicircular or the like. 5 shows an alternative to the guide runners 15 in the form of longitudinally formed guide grooves 28 on the underside 14 of the device 10. These guide runners 15 or guide grooves 28 substantially improve the directional stability when steering the device 10 when sliding over water, snow or earth.

2 and 3 in the area of the front wall 12 also show holding means 31 which allow the user to hold himself on the device and to influence the steering of the device 10.

The device 10 according to the invention permits sliding movement processes on the water because, due to its buoyancy properties, it is buoyant and particularly easy to steer with the aid of the guide grooves 28 or guide runners 15. Therefore, it can be used as a surfboard for surfing, but also as a swimming aid. Due to its physical training and the provided guide runners 15 and the guide grooves 28, it can also be steered on snow and ground, so that it can also be used like a sled. This essentially differentiates the device 10 according to the invention from the devices known in the prior art. It does not sink deeply in snow and water due to its buoyancy properties, and it is particularly suitable for users of all ages and body weights.

The device 10 'shown in FIGS. 7 and 8 is in principle constructed in exactly the same way as already described with reference to FIGS. 1 to 6; therefore only the differences are shown below. The same reference numerals are used for the same components, which are only differentiated by a prime for the sake of understanding.

The device 10 'shown in FIGS. 7 and 8 has a different design of the sliding shell 11' than the device 10 described in FIGS. 1 to 6. First, to improve the overall stability of the device 10 ', the sliding shell 11' is provided with a U-shaped frame 41 which is formed from the opposite side walls 13 'and a corresponding design of the front wall 12'. Furthermore, the guide runners 15 ', which are triangular in cross section in the exemplary embodiment, extend over half the length of the device 10', the middle guide runners 15 'extending almost into the region of the arched front wall 1'.

The triangular shape of the guide runners 15 'can also be designed differently. Thus, in the exemplary embodiment, the middle guide skid 15 'is higher than the guide skids 15' arranged to the left and right of it and includes, for example, an angle of approximately 60 °, while the other two guide skids 15 ', for example, enclose an angle of approximately 90 °.

To improve the directional stability, concave guide grooves 28 'are formed between the guide runners 15'. In the exemplary embodiment, the. Guide grooves 28 'in their length approximately up to half the length of the device 10' and in their width from the guide skid 15 'to the guide skid 15'. This training additionally improves the stable straight running of the device 10 '.

Finally, an inclined surface 42 is provided on the underside 14 'of the sliding shell 11' in the region of the opposing longitudinal edges, which extends from the rear end 19 'of the sliding shell 11' to the region where the curved, raised front wall 12 'begins , The inclined surface 42 has a triangular shape, starting broadly at the rear end 19 'and ending in a point in the region of the front wall 12'. The angle of the inclined surface 42, which leads from below the underside 14 'of the sliding shell 11' to the side wall 13 ', is approximately 5 ° to 20 °. Experiments have shown that an angle of approximately 10 ° gives the device 10 'optimal steering properties through body displacement of the user. The steering and braking properties given by the individually actuated brake levers 30 'are of course fully retained.
