The present invention relates to a wheeled device for entertainment and/or sports, driven by a foot, and supporting structures, used with him. The preferred device for leisure time involving physical movement, are various designs of rolling on wheels and driven with the help of legs, of which the most popular in the decades around the world have received a traditional bike, which involves sitting in the saddle and putting it in motion through the pedals. In addition to the rental, which are relatively complex structures, there are many other, more simple wheeled devices smaller for entertainment powered by the legs, allowing sports such as roller skates, which are attached to the feet of the user, or a two-wheeled scooter that has handlebars like a Bicycle wheel, and a long thin plate to which the front and rear end attached wheels, and the user has one foot on the plate, driving the scooter with the other leg. Becoming increasingly widespread, the so-called skateboard which has four wheels of small diameter, and standing on it, the user sets it in motion as a scooter, and decl is authorized surface, the user can stand on the Board with both feet and roll forward using the body to maintain equilibrium. Finally, it was mentioned that there is a device for sports and entertainment, driven by pedals, which has one wheel with spokes of this type, as used in the rental, the use of which, however, requires the user art of balance, possessed by few people, so that such a device is not able to become a product that would be widely spread, even in the form of a stabilized servo motors, which, of course, increase production costs to a considerable extent.

In connection with the above skateboard it should be noted that although it is a very useful device for entertainment, it is quite slow and less maneuverable due to the very high resistance of its four small wheels. In addition, there is the objection of the skateboard from the point of view of safety, because if the user falls, for example, or for other reasons leave this sports vehicle, it can move freely and, for example, on an inclined road can go on and cause an accident.

The problem to be solved by using the present invention is to provide a wheeled device for entertainment or sports, driven movement is the foot, which makes movement and actuation similar way as is done with a skateboard, but which, however, is much faster and more maneuverable, easier to aim and more favourable from the point of view of security.

The basis of the present invention is the understanding that when using, for example, one of a spoked wheel with a rubber tire of such size as is used for rental, you can create a device that is actuated by the foot, as when using the scooter, the user can move with greater or lesser speed, until the wheel rotates with a fork, in which the bearings are installed, the axis of the wheel, and the plug has at least one supporting element for the legs, preferably one item at a time, continuing on each side is much below the wheel axis, close to the bridge, which is rolling the wheel or on one of which the user device is one foot, pushing at the same time, the device with the other leg. In addition, it was found that such a device can be equipped with two wheels located directly next to each other, is displaced in the lateral direction relative to each other, if the wheels are connected in the longitudinal direction and is installed in the lateral direction so that they can rotate relative to each other.

Based on this understanding of the task was solved using wheeled devices for entertainment and/or sports, driven by repulsion from the earth's surface, sidewalk leg corresponding to the present invention, which is characterized by the fact that:

has a wheel that can rotate around an axis, and the foot plates, the continued outward below the specified axis, with the wheel located between the two side plates fixed attached to the wheel axis, and the foot plates are formed as bent outward continuation of the side plates and rigidly attached to the lower end region of the side plates which are formed so that during normal use of the device they continue up above the knee of the user standing on one or both plates to the legs and to provide the function of the friction supports for the knees or shins. In the interests of increasing the resistance of the device practical, if the side plates are connected together in the form of a fork through the connecting rib or ribs, continuing along their edges.

In accordance with another example of the construction of the ends of the axle are fixed in thickened flat parts of the side plates and in the practical case installed in them.

In addition, preferably, if the reservoir is by foot located at the maximum distance from the axis of the wheel, ensuring the correct operation of the device is almost the distance from ground level in the working position of the device, which makes the operation possible, preferably at the same level.

Characteristic of another embodiment of exercise device is that the side plates are circular plates, the shape and size of which essentially correspond to the shape of the wheels, and curved, convex, as seen from the outside, the connecting rib continuously along the edges of the side plates except for the holes that allow protrusion of the wheel rim.

In accordance with an additional characteristic of the invention, the side plates are made so that they only partially cover the lateral side of the wheel, preferably in such a way that near the axis of the wheel width is the least of this area in the direction of up and down their width increases.

It may be the preferred form of construction, if it has a bearing housing surrounding the axle, and a wheel rim with a rubber pneumatic tire, and a wheel connected to the bearing housing by means of spokes; in addition, if the device has a steering rack that is directly or indirectly connected with the side plates.

In accordance with another characteristic of the invention at the height of the legs of the user is La, using the device has a support plate attached to each of the side plates parallel to the axis.

Another driven wheel leg device for entertainment and/or sports, with plate for feet, also is an object of the present invention, characterized in that

has two parallel wheels, separated by some distance, located offset relative to each other in side view, which are connected to each other via a connecting element, which prevents the movement of the wheels in the longitudinal direction relative to each other, but allows rotation of the wheels relative to each other;

the bearing housing of the axes of the wheels protrude from the plane of the wheels and these projecting parts of the bearing housing connected to the supporting elements;

the foot plates are connected with the lower parts of the supporting elements, and above them there are side plates attached to the support elements, continuing above the knees of the user when using the device. Practically, it is expedient if the device on the side view has a configuration in the form of an inverted V, and in the top view - Z-shaped configuration, the connecting element with an offset curved rods connected between a connecting edge located in the plane of the wheels,and in a practical case from the lower end of each of the rods is down vertical pin; these pins are mounted in bearings fixed in the side bearings of the axes of the wheels that protrude inward from the plane of the wheels. In addition, preferably, if the device has a curved supporting elements, which extend up to the upper area of the wheel. In accordance with another characteristic of the invention the wheels are displaced relative to each other to such an extent that the contour line of one wheel is located near the axis of the other wheel, in the practical case of separation, equivalent to 1-5% of the wheel diameter. Reasonably, if the wheels are connected to each other using one or more springs so that they can be rotated from each other, despite the force of the compression spring; and the device has blocks that prevent prevent contact of the wheels, which are moved back into their initial position by the spring or springs. In this case, preferably, if the springs are located on the lower and upper part of the device, while in the practical case, the upper edge of the side plates are connected by two springs and one spring is inserted between the plates for the feet. Can also be good, if on the inner side of the lower ends of the rods connecting elements are blocks; and, if there are blocks on the outer sides of the bearings receiving the vertical pins.

The object of this is to Britania also relates to support structures, designed for use with the above-mentioned device for entertainment and/or sports, to reduce friction between the user device and the side plates, the essence of which is that there is a design, type of carriage, which can be fixed on the knee of the user using the device, by means of redundant connections, and in this construction there are protruding rollers placed at the side facing the side plate, and the side opposite this side is a surface curved to fit the shape of the knee. The peculiarity of the case for supporting the design is that if the side design, type of carriage, has a rectangular - in this case, with rounded corners - base, in the region of the corners there are cavities formed in a flat surface, and in these cavities installed the axis of the rollers, and the opposite side has a curved shape. Virtually preferably, if the rollers are 1 to 3 mm, preferably from a flat surface, facing to the side plate. It may also be preferred if the design type of the cradle has a connection (connection), consisting of connecting elements type hook-loop.

Hereinafter the present invention will be detailed what about described with reference to the accompanying drawings, are examples of preferred structures of wheeled devices for entertainment and/or sports, driven by foot, and some constructive partial solutions. In the above drawings

The device for entertainment and/or sports in General illustrated in figure 1 and Figure 2, has a wheel, indicated by the reference number 1, which, for example, like the conventional Bicycle wheel with spokes or may be of a design similar to the design of the Bicycle wheel. In line with this it has a Central axis 3 and the bearing housing 6 surrounding it, which is connected by means of spokes 5, shown in dotted lines, with the rim 2A of the wheel, which has, as is known in itself, a pneumatic rubber tire 2 mounted on it (for clarity in figure 1 shows only a few of the spokes 5). The geometric axis of rotation of the wheel 1 is marked with the letter X.

In accordance with the present invention the device has a plug 4, which transmits the load of the weight of the user 15 using the device, the circumference of the wheel 1 is much lower than the geometric axis x of rotation, which is on view in cross-section (Figure 2) has the shape of an inverted U, the element type of the box with the article is Minami, down, which in the case of this design is essentially circular, as viewed from the side, the flat side plates 7, 8. In this case, the side plates 7, 8 are only "essentially" round, because in the middle of their lower end part no part in the form of a sector of length h (Fig 1), which, as can be seen from Figure 3, has a height of m. When the side plates 7, 8 are connected to each other by a curved connecting ribs 14, the speaker, if you look on the outside, which continues along most of the periphery of the side plates 7, 8, in other words, it continues to the two end points of the cut out portion in the form of a sector, which we have already mentioned, when formed rigid fork 4, box type, on the lower part of which has a hole (see figure 1 and figure 2), which has length h, width b, the edge of which lies at a height of m above the level t of the ground, sidewalk, when the user 15, shown in figure 1 and figure 2, correctly uses the device. If the total height of the device above the level t of the earth is H, then the geometric axis x of rotation of the wheel 1 is located at a height H/2 above the level t of the earth. Axis 3 of the wheel 1 shown in figure 1 and figure 2, rigidly fixed to the thickened flat parts 7a, 8A of the side plates 7, 8 of its ends, and practical, if these thickened flat portion 7a, 8A of the plate location is us so, what geometric axis x of rotation passes through the center point. Axis 3 can typically be made of steel, and the plug 4 is made of polyester with fiberglass; and this material if its thickness is of sufficient magnitude, can provide reliable fixation of the axis 3.

The bottom plate 9, 10 foot, protruding on both sides, are directly connected to the side plates 7, 8, in the practical case formed as one piece with the fork 4, in other words, they are plates that provide support for one or for the other leg, and the user 15 using the device, is - based - one foot on one of them while the other leg pushes the device intermittent rhythmic movements from level t of the earth just as it is done when using the scooter. The support leg push and leg can even change roles during the movement. As can be seen in figure 1, in side view, plate 9, 10 for the legs are located in the circumference of the wheel 1, and to the extent possible under the geometric axis x of rotation. The height of the side plates 7, 8, in other words the plug 4, is selected such that its upper edge continues on lap 21 user 15 using the device when he/she correctly uses the device (Figure 1).

The stability of the device in the process used the I increases with increasing distance in other words, plates 9, 10 foot located below the x-axis of rotation, that is, the distance m between the level t of the earth, the surface of the pneumatic rubber tire 2, rolling on it, and the plates 9, 10 feet; and through the plug 4, the user device 15 pressurizes the axis 3 of the wheel 1 under the geometric axis x of rotation near the outer circumference of the wheel 1, almost touching the level t of the earth. We would like to point out that practical only if the plates 9, 10 foot starting from the longitudinal edges of the holes 11, in other words they are perpendicular to the geometric axis x of rotation and formed as bent outward continuation of the side plates 7, 8, or rigidly attached to the lower end region of the side plates, but of course they can be located above.

In this application it is mentioned that the device shown in Figures 1 to 3 has a plug 4, mainly for reasons of stability, the device has side plates 7, 8 and plate 9, 10 for the legs, which are crucial from the point of view of the device as a joint action between the user's foot 15 using the device, asymmetric loading device, and the wheel 1 is created by the force of friction between one of the side plates 7, 8 and tibia as a result of the horizontal reaction force torque, POPs Aviemore asymmetrical power load during variables (or unilateral) cycles support-pushing.

The plug 4 can also be supplemented steering rack 13, similar to the steering rack, used on bicycles, with a lower fork end, which also serves to higher stability in the plane of motion and balancing unbalanced loads, and this makes using the device safer, requiring, thus, less skill, so it is required mainly for beginners during their training. Similar can be said about the supporting plates 12 that are parallel to the geometric axis of rotation, on which the lower leg support leg may encounter in the process. The front plate 16 of the plates 9, 10 for the legs to prevent slippage of the feet forward, they are not required experienced user.

Plug 4, described in detail above, in addition to the holes 11 completely covers the wheel 1, but this is not essential. Partly to reduce the weight of the device, and partly to save material may be preferred application of the fork 4A, shown in Figure 4 and Figure 5, the side plates which are formed by cutting out a deep section of the side plates 7, 8, shown in Fig.1-3. In this case, the side plates have a minimum width e of the line of the geometric axis x of rotation, and above and below - projecting parts - the maximum width of f and is the raised convex, as can be seen above and below, and concave, as can be seen from two sides, and these elements are connected to each other by the connecting edge 18 at the top and two short connecting ribs 19 at the bottom. Width e, of course, must be selected such as to provide sufficient space for the frictional connection between the shank and the side plates 17.

The use of the device for entertainment and/or sports, is shown in Figure 1-5, as follows:

The user 15 using the device, as we have already said, pushing the device through movements similar to the movements that make when using the scooter. One leg, the left leg in accordance with Figure 4, the load device being asymmetrically placed on the plate 9 to the leg, and right leg provides the pushing and after pushing off from the level t of the earth this leg, then put on the right plate for 10 feet (Figure 2) and then the left leg performs a pushing motion, as we can see in Figure 5. Thus, the forward movement occurs when alternating standing on plates 9, 10 foot and repulsion, but not necessarily to repulsion and standing always been different legs, multiple aftershocks can be done with one foot and then on the other side. Twisting force arising as a consequence t is Scania, balanced by the force applied in the opposite direction of the Shin of the user 15 using the device.

After reaching a higher speed, the user 15, using a device that can continuously stand on both plates 9, 10 for feet and move forward along a sinusoidal line, known of the movements of the users who use skateboards. At this time, the force required to move forward, can be realized by alternating left and right hips with steering and rocking her hips, in other words the actual control movements, including tremor hips. If the device is also equipped with a steering rack 13 (figure 1 and figure 2), the control of movement and maintenance of wheel 1 in the vertical plane is provided the steering rack 13 and the connecting rod, which forms part of it. Steering rack 13 provides the ability to install brakes and also the ability to slow down the device during movement, which can increase the resistance in the plane of the wheel 1. The brake can be block brake, as used in conventional bicycles, which can be installed in front of the upper section of the plug 4, which receives the wheel 1. Work the cable may lead to the capture of the steering rack belonging steering rack 13, which may free the bottom to hold in the hand.

Especially in the period of study product use the use of accessory design - slide insert - marked position 20, in General, it may be practical, which is designed to reduce the friction during the pushing device between the plug 4 and knees 21 user 15 using the device. The supporting structure 20 has a rectangular shape, preferably rectangular base 22, the inner surface 23 of which is related to the knee 21 has a concave curve, and the outer surface 24 on the plug 4 when using the device is a straight flat surface. In the four corners of the base 22, where it has the greatest width, as follows from Fig, there is a cavity 26 in the flat surface 22, in which the rollers 25, which can be rotated around the z axes fixed position, so that their surface protrudes from the plane of the surface 24 at a distance ofalmost amounting to 1-2 mm, for Example, the length h of the base 22 may be 10-12 cm, and its width s can be 4-6 see As a result of the construction described above, the supporting structure 20 is a structure of type carriage, which can roll on the other surface of the fork 4 and which can be attached to the knees is m 21 user through redundant connections, for example, through connections 27 type hook-loop 28. As is evident from Fig.6 and Fig, two parts 27A, 27b connections attached to each support structures in the field at the ends of the shorter edges of the base 22, which cover the knee 21 and attached to each other by means of hook and loop 28, and, thus, creates connections 27, shown in Fig.6.

On Fig.9-16 shows a further design of the device for entertainment and/or sports. This device has two wheels 31, 32 of the same diameter, located directly next to each other, is displaced in the lateral direction relative to each other, overlapping each other almost to the axes 45, 46; the outer surface of the tire 41, 42 is located at a minimum distance of 1, approximately 1-5% of the wheel diameter from the axis of the other wheel. Two wheels 31, 32 are connected on one side via a connecting element 33, as shown from Fig-16, obtained, for example, of rigid pipe, which in the transverse direction has the shape of an inverted V with curved rods 49A, which are offset in the transverse direction relative to each other in the top view, as shown in Fig, connected by short horizontal upper edge 49b, so that in the top view of the connecting element has a Z-shaped configuration, and the pins 38, 39 protrusion is t down from the upper end of the rods 49A, and towards the lower end of the rods 49A are blocks 54, 55, protruding inside; the role of these pins and blocks will be described below. The connecting member 33 covers the wheels 31, 32 with a distance of several millimeters from buses 41, 42, his rods 49A are in the plane of each of the wheels 31, 32 and they can be as wide as the tire. You must specify that in this case the wheels 31, 32 are Bicycle wheels, rim 41A of the wheel is not connected to the housings 47, 48 of the bearings by means of spokes, but through a solid, rigid plates 43, 44 to the wheel (Figure 10).

Above the housing 47, 48 of the bearings should be almost done with bushings, width and load-bearing capacity which is greater than that of a regular Bicycle bearings, and on two sides of it protrudes from the plane of the wheels 31, 32 on the side surfaces of pneumatic rubber tires 41, 42, as seen in the vertical plane. From Figures 9, 11 and 12 it is obvious that a rigid curved support element 34, 35 is connected to each protruding end of the housings 47, 48 bearings, made of a solid (for example, metal or plastic) plate or rod and on one part of its function should provide the ability to attach the side plates 40 (figure 10 shows only one of the side plates for better understanding), and on the other side to their top to the Tsam 36, 37 plate attached to the legs, each upper end is located at a minimum height of m above the surface t of the earth, i.e. in this case the distanceunder the axes 45, 46 to the plates 36, 37 foot should be in practice as much as possible.

The bearing 52, 53 for receiving the vertical axes 38, 39 of the connecting element 33, protruding downward is connected with each end of the housings 47, 48 bearings - bushings - projecting inward. Thus, as shown in Fig, when the wheels 31, 32 are located next to each other, and the connecting element 33, which in the top view has a Z-shape, combined with the bearings 52, 53 their axes 38, 39, between the wheels 31, 32 are formed connection, where their longitudinal position shifted relative to each other in the transverse direction is fixed, and thus, the wheels can be moved close alongside each other and, at the same time, as follows from Fig, they can turn in the opposite direction relative to each other so that the device is easy to control and has the ability to change directions. However, although the device user can easily rotate the wheel 31, 32 to the outside, pressing his foot to the right, turning his back from the positions shown in Fig cannot be properly carried out only by force, which go active is devaysa leg, so in accordance with the invention in the lower part 51 of the connecting plates 36, 37 feet, built in the spring and two spring 50 is embedded in the upper portion for connecting the side plates 40 having the shape of a bone plums (Figure 10), overlapping curved support elements 34, 35 - their upper edges to provide possible and easier turning back wheels 31, 32 in their basic position shown in Fig. To stop the grip of the two wheels to each other in the result of application of force of the springs 50, 51 built above the blocks 56, 57 and 54, 55; blocks 56 and 54 and blocks 57 and 55 are adjusted relative to each other and prevent the adhesion of the wheels 31, 32 to each other.

Curved support elements 34, 35, plates 36, 37 foot, the housings 47, 48 of the bearings and the vertical axis 38, 39 device according to the invention, described above, form a rigid node on which you can rotate the wheels 31, 32.

The device for entertainment and/or sports shown on Fig.9-16, is used so that the user brings the device in action movements similar to the movements when using the scooter, and thus, the user can rotate the device to balance or change directions; rotation becomes possible by moving the plates 36, 37 feet from his legs. Due to the rotation of the front wheel left the device turns l is Oh, and thanks to the rotation of the rear wheels left the unit turns to the right. The main position, providing rectilinear motion, as described above, is provided by springs 50, 51.

Standing on the plates 36, 37 foot, the user asymmetrically load the device. As a result of the unbalanced load on the knees is formed a horizontal reaction force, which provides a joint operation of the device and the user's legs; and there is a reaction supports and runs on the device through the side plates 40.

The use of auxiliary structures 20 - small design, the type of carriage is shown in Fig.6-8, attached to the knee as a fulcrum, it is recommended mainly in the period of the training device for entertainment and/or sports. The position of the auxiliary structures 20 in use is shown in Fig.6, where the structural elements described above, indicated already used the reference positions. For simplicity, the use of auxiliary structures 20 are described only with reference to the device of figure 1-5, but, obviously, they can be used differently with the device shown in Figures 9-16. The user uses the device, standing with both feet on the plates 9, 10 for the legs in the position shown in Fig.6, maintaining against VI is CI 4 auxiliary structures 20, attached to the lap 21 user each of the two connections 27, and the user moves, rolling on the wheel 1. Bearing between the plug 4 and knees 21 provided by low friction - rolling - intermediate support structures 20 gives the user the ability to a lesser extent, to shift the center of gravity of his body forward or backward, making it easier balancing and increases stability during movement.

The advantage of the present invention is that the resistance of the device little - primarily due to the large diameter of the wheel - it is significantly less than the resistance of the other similar devices for entertainment and/or sports, such as skateboards, and the device can easily control small movements of the ankle. Due to the fact that in that case, when the user comes with this vehicle, it immediately breaks, stops rolling and remains lying on the ground, it is significantly less risk of accident than skateboards, which in this case roll freely in and of themselves. The advantage of supporting the design is that it simplifies the training in the use of the vehicle.
