Abstract
Description
- The invention relates to a vehicle for recreational use, for example on closed terrains with a relatively flat ground.
- In the market of recreation, game and leisure activities, vehicles play an important role. In this context, one can think of vehicles which are amusing to drive, for example because they have an unusual way of operating. Such recreation vehicles should have characteristics of manoeuvrability, should appeal to the adroitness of the driver and give him a sense of speed, because it is proven that good ingredients for amusement and relaxation are then present. For group arrangements, it can be desired that the vehicle is suitable to be able to create a game or match element, for example by being able to let multiple of said vehicles drive together or against each other.
- Several types of such recreation vehicles already exist.
- It is an object of the present invention to provide a new type of recreation vehicle. To that end, a recreation vehicle according to the invention has the features as described in
claim 1. A person can stand on the drive unit, and tilts the rotating drive member against the ground, by using his weight, whereby the vehicle displaces itself in a direction depending on the direction in which that person tilts the drive unit. - With a recreation vehicle according to the invention, one will be able to displace oneself standing upright with large manoeuvrability and with a large sense of speed. Further, such a vehicle will be easy to operate, and it can move on on practically any flat, relatively hard ground, such as for example concrete floors and asphalt or the like, but also on snow or ice.
- Hereinafter, the invention will be further explained with reference to the attached drawing, in which:
- figure 1
- shows a schematic longitudinal section of an embodiment of a recreation vehicle according to the present invention with the drive unit in the neutral position,
- figure 2
- shows a bottom view of the recreation vehicle of figure 1, and
- figure 3
- shows a longitudinal section of the recreation vehicle of figure 1 with the drive unit in several tilted positions.
- Figure 1 shows a longitudinal section of a
recreation vehicle 1 according to the present invention. Therecreation vehicle 1 comprises abase frame 2 resting on a number ofwheels base frame 2 may in principle have any contour, but preferably has a round shape, for example an elliptic or oval contour, as illustrated in figure 2. In this example, the number of wheels is equal to four. Preferably, onewheel 3 is fixedly mounted to thebase frame 2, and theremaining wheels 4 are swivelling rollers capable of swivelling fully (360°) about their vertical axis. Thebase frame 2 has a top surface suitable for at least one person to stand on. Preferably, abracket 6 or other supporting member is attached to thebase frame 2, to which supporting member the person or persons can hold themselves. - The
vehicle 1 is provided with adrive unit 10 to be operated by body weight. Thedrive unit 10 comprises amanipulation member 15, which in this example is a foot platform and extends above thebase frame 2, and adrive member 17 situated below thebase frame 2, which drive member is rotatable about arotation axis 16 relative to thefoot platform 15. Relative to thebase frame 2, thefoot platform 15 is fixed against rotation about therotation axis 16. Thedrive unit 10 can tilt about two mutually perpendicular horizontal axes relative to thebase frame 2. In a suitable embodiment, thedrive unit 10 is coupled to thebase frame 2 by means of aball joint 11. Thedrive member 17 is driven by amotor 18 which is mounted to thefoot platform 15. Preferably, themotor 18 is an electromotor which is supplied by batteries. Preferably, themotor 18 is positioned centrally on thefoot platform 15, and a driven motor shaft extends downward through theball joint 11, and thedrive member 17 is directly mounted on the motor shaft. - Figure 2 shows a view on the bottom side of the
recreation vehicle 1. Thevehicle 1 has acentre 13 and avertical centre plane 14 defining a longitudinal direction of thevehicle 1. Thefixed wheel 3 has a wheel rotation axis 3a perpendicular to thecentre plane 14, and is located at an end of thebase frame 2 which will be indicated as rear end. Theball joint 11 is situated in thebase frame 2 and on therotation axis 16, wherein thecentre 13 is situated between theball joint 11 and thefixed wheel 3. - In a neutral position of the
drive unit 10, as shown in figure 1, therotation axis 16 is directed vertically, and thebottom surface 19 of thedrive member 17 is situated at short distance of a ground on which thevehicle 1 stands. Since there is no contact between thedrive member 17 and the ground, thevehicle 1 will stand still or move straight on with constant speed. If thefoot platform 15 is tilted, thedrive member 17 tilts along and touches the ground with itsbottom surface 19. The tilting is illustrated in figure 3, in which the recreation vehicle of figure 1 is shown with the drive unit in two different tilted positions. The rotatingdrive member 17 then exerts a friction force on the ground; for a good friction contact with the ground, thedrive member 17 is provided at its bottom side, at least at its peripheral edge, with alining 12 of rubber or synthetic material. The material and the profile of thislining 12 may be adapted to the type of ground, for example concrete, ice etc. As reaction to the friction force, thevehicle 1 experiences a thrusting force, of which the direction depends on which part of thedrive member 17 touches the ground, and thus on the tilting direction of thefoot platform 15, which tilting direction can be influenced by the driver by displacing his weight. This is further illustrated in figure 2, in which thelining 12 is shown shaded. The direction of rotation of the drive member 7 is shown with a round arrow. The straight arrows represent the directions of the respective forces which are exerted on the vehicle when a part of thelining 12 touches the ground at the position of the origin of the arrow. - The particular characteristic of the recreation vehicle proposed by the present invention is therefore the way of driving, by means of the
tiltable drive disc 17, of which therotation axis 16 is substantially directed vertically in a neutral position. By tilting thedrive disc 17, a circumferential part of that disc comes into contact with the ground, and the reaction force drives the vehicle. - In the described embodiment, a
manipulation member 15 for manipulating the tilting of thedrive disc 17 is implemented in the form of a foot platform. The driver stands on that platform, and tilts thedrive disc 17 by means of a weight displacement on the platform. If desired, the driver can hold on to asupport 6 which is directed upward relative to the base frame. In an alternative embodiment, the driver might stand on the base frame, and a manipulation member could be implemented as a grip which is directed upward relative to the base frame, similar to thesupport 6, which grip is coupled to thedrive disc 17, so that the driver can tilt the grip with his hands and thus can tilt thedrive disc 17. - The drive direction depends on the tilting direction of the
drive disc 17. In the embodiment described, themanipulation member 15 is directly coupled to thedrive disc 17, so that a forward tilting of themanipulation member 15 corresponds to a forward tilting of thedrive disc 17, in which case a front part of thedrive disc 17 comes into contact with the ground and the reaction force is thus directed to the left or to the right, depending on the direction of rotation of thedrive disc 17. In an alternative embodiment, a coupling accommodated between themanipulation member 15 and thedrive disc 17 is provided, which coupling rotates the tilting direction of thedrive disc 17 90° relative to the tilting direction of themanipulation member 15. Themanipulation member 15 and thedrive disc 17 may for example be tiltably mounted to the base frame independent of each other, by means of respective ball joints or the like, and a system of cross- coupled bars couples themanipulation member 15 to thedrive disc 17. For example, four of such bars are provided. Each bar has a first end and a second end. The first end of a bar is pivotably coupled to themanipulation member 15, at certain distance from therotation axis 16. The second end of that bar is pivotably coupled to thedrive disc 17, also at certain distance from therotation axis 16, and at an angular position which is shifted 90° relative to the position of the first end. The said distances are preferably mutually equal. - In such an embodiment, a forward tilting of the
manipulation member 15 corresponds to a lateral tilting of thedrive disc 17, wherein a lateral part of thedrive disc 17 comes into contact with the ground and the reaction force is thus directed forward, depending on the direction of rotation of thedrive disc 17. - It will be clear to a person skilled in the art that the scope of the invention is not limited to the examples discussed in the preceding, but that several variations and modifications thereof are possible without diverting from the scope of the invention as defined in the attached claims.
- Instead of wheels, for example rolls, slide irons, skis, etc. may be implemented, in general to be indicated as guide members.
- In further variations, it is possible that the driver of the vehicle sits on the base frame, and operates the drive unit by hand by means of, for example, a joystick.
- It is further possible that the drive means are situated on the base frame and energize the drive unit by means of a transmission.
