    专利说明:

    Here, the term "vehicle" includes, but is not limited to, a snow or ice sled, or any other type of surface on which the vehicle can be driven. Here the term "with" includes, but is not limited to skis.
    The vehicle according to the invention can also be provided with slides in the form of wheels for surfaces other than snow or ice, such as conventional road surfaces.
    According to another aspect of the invention, the vehicle, which is typically a sled, has four slides arranged for steering with four slides. The runners can be arranged in two separate control systems, a front control system and a rear control system, or in a combined control system.
    In this way, a vehicle is steered with four runners, which typically have separate steering systems at the front and rear. The vehicle according to the invention, which is typically a sled, is particularly useful for slalom driving on a snow or ice surface.
    According to an embodiment of the invention, the front steering system is attached to the steering wheel, typically in that it is part of the former and the rear steering system is attached to the seat and actuates the latter, which can be tilted to steer. In this way, both the steering wheel and the seat can help each other and be controlled independently by a user to steer the carriage.
    According to another embodiment of the invention, the front steering system comprises steering equipment arranged to operate according to the Ackerman principle and the front runners are attached to struts at an angle to the frame so as to provide carving of the inner edges when pivoting. Typically, the struts are directed backwards. In this way, steering is improved even more compared to known sleds with only one with a device arranged for steering.
    According to another embodiment of the invention, the vehicle further comprises a plow brake device arranged and operated by the front runners. In this way, the braking effect is significantly improved by using plow braking compared to conventional braking of sleds that do not use the front runners for braking.
    Further advantages and features of embodiments of the invention will become apparent upon reading the following detailed description taken in conjunction with the drawings.
    BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows a perspective view from above of a vehicle in the form of a toboggan according to an embodiment of the invention.
    FIG. 2 shows the same sled as shown in FIG. 1 from below, FIG. 3 shows the same sled as shown in FIG. 1 and 2 from above, with the runners in the left turn position, FIG. 4 shows the same sled as shown in FIG. 3, positioned with the runners in the left turn position, from the rear, FIG. 5 shows a side view of a sled with a brake according to an embodiment of the invention, FIG. 6 shows the same sled as shown in FIG. 5 in a top view showing the position of the runners during braking, and FIG. 7 shows a side view of a sled with a brake according to another embodiment of the invention.
    DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION FIG. 1 shows a perspective view from above of a vehicle, here a toboggan 1, according to an embodiment of the invention. The sledge 1 comprises a frame 2 provided with a seat 3 thereon, a knob 4 arranged in a front part of the frame 2 and four slides 5a-d attached to the frame 2. The four slides 5a-d are arranged in two separate guide systems, a front control system 5 ', which includes a pair of front members 5a, b and a rear guide system 5 ", which includes a pair of rear members 5c, d.
    The sledge 1 shown in FIG. 1 is only a non-limiting embodiment of the invention.
    For example, the number of sliders may be three instead of four, where a front slider is part of the front control system and the two rear sliders are part of the rear steering system. Furthermore, according to a further alternative embodiment of the invention (which is not shown) only the rear feeders can be arranged for control. The front and rear control systems can also alternatively, without departing from the design, be combined in a common control system.
    Here, the term "forward" including "front" refers to a part of the sled 1 which is normally first in a forward direction during use.
    The runners can be designed as skis adapted for use on a snow or ice surface, but can also be adapted to any other type of surface such as a surface without snow or ice, including a road surface. The runners can then include wheels, or two-axle bogies for example. Referring again to FIG. 1 and the embodiment of the invention shown therein. The frame 2, which is typically made of galvanized steel, or aluminum tubes, includes longitudinal straight tubes 2a, typically having a larger diameter than the rest of the tubes. Attached thereto are two substantially U-shaped front legs 2b on each side thereof and two U-shaped rear legs 2c which are bent slightly downwards (seen in a normal position in use) to which the seat 3 is attached by means of fastening elements 2d such as bolts so that a sledge 1 provided. The diameter and thickness of the pipes are typically from 15-25 mm in diameter and up to 2 mm wall thickness, but can vary depending on the load and stiffness requirements.
    Typically, but not limited to, the frame 2 is made of separate pipe parts which may be partially inserted into each other and secured to provide a frame 2 made of pipe, for example to facilitate transport before mounting in flat cardboard packages. Some couplings may also be welded or riveted.
    The seat 3 is typically made of polymeric materials such as plastic, including foam, or sheet material coated with foam and plastic. The shape and size of the seat 3 can be any suitable for a sled carrying a child, an adult or even two people.
    Typically, the seat 3 is attached to the frame 2 by means of suitable fastening elements such as bolts, or screws, in a front part of the seat and with suitable flexibility so that it can return to its original position. The seat 3 can also be attached to the frame in some other way, provided that control with rear slides can be provided, without departing from the invention.
    The steering wheel 4 and the runners 5a-d can be made of plastic or some other suitable material, provided that requirements for rigidity, temperature and abrasion resistance, etc. can be met.
    The material, design and dimensions typically depend on the type of surface on which to drive.
    The steering wheel 4, which is typically angled towards a user, is typically arranged to a guide component 4a which comprises guide rod 4b into which the guide shaft 4c runs. The guide shaft 4c is attached to the steering wheel 4 at one end 4c 'thereof and attached to link arms 4d by means of the guide plate 4e. The link arms 4d are connected to a respective one with 5a, b by means of a respective front guide link 4f, g so that the runners 5a, b can typically be guided according to the Ackermann principle by means of the steering wheel 4. The Ackermann principle means that an inner slide bar swings more than an outer slide bar when swinging to compensate for slipping of the sliding rods when turning. As this principle is well known to those skilled in the art of vehicle design, it will not be described in more detail in this publication. A vehicle without Ackermann steering is also conceivable. The front runners 5a, b are typically attached to the frame by means of struts 6 angled backwards (seen in a normal direction of travel N) so that they can swing up and down slightly to be able to follow uneven ground at high speed. When the struts 6 are angled, the runners 5a, b will be angled during pivoting, which means that the inner edges (in a turn) of the runners 5a, b are pressed downwards towards the ground, which gives better tracking. The struts 6 are attached to the frame 2, typically by means of fastening elements such as rivets and to the guide links 4f, g. The struts 6 and front left and right guide links 4f, g can be made as an integral part or be separate parts permanently joined.
    Reference is now also made to FIG. 2 showing further details of the front control components.
    The guide links (not shown in FIG. 2 when hidden by the sliders 5a, b) are attached to the front link arms 4d described above. The front link arms 4d are attached to the front guide plate 4e, which is attached to the guide shaft 4c. When a user turns the knob 4, to guide the front runners 5a, b, the guide shaft 4c rotates inside the guide rod 4b which passes through the central pipe part 2a of the frame 2.
    The rear runners 5c, d are also attached to the frame 2 by means of struts 6 (see FIG. 1) and angled forward (seen in the normal direction of travel N) in the manner described above in relation to the front runners 5a, b, with rear guide links 4h, i (see FIG. 1) which are attached to rear link arms 4i (see FIG. 2). The rear link arms 4i are attached to a guide plate 9 connected to a pivotable guide part 11 attached to the seat 3 so that it 11 can pivot around the central pipe part 2a of the frame 2 when the seat 3 is pivoted. In this way, the rear slides 5c, d can also be controlled, which facilitates control of the sledge 1.
    This is shown in more detail in FIG. 3, showing the same sled as shown in FIG. 1 and 2 in a plan view from the front, with the runners 5c, d in the position for turning to the left (seen in the normal direction of travel N) according to the Ackermann principle to improve tracking. The Ackermann principle means that the inner front member 5a is rotated more by an angle o1 than the outer front member 5b, which is rotated by an angle o2. It can also be seen that the rear runners 5c, d are positioned to steer slightly towards the front runners 5a, b as their guide angles are smaller than those of the front runners 5a, b. This improves tracking even more.
    FIG. 4 shows the same sled as shown in FIG. 3, with the runners 5a-d in position for turning to the left, from the rear side. It is clear how the runners 5a-d are positioned in relation to each other as described above. The seat 3 is angled when the rear runners 5c, d are in the position for turning to the left. Referring now to FIG. 5, which shows a side view of a sledge 1 with a brake according to an embodiment of the invention and to FIG. 6, which shows the same sled as shown in FIG. 5 in a view from above showing the position of the rear runners 5c, d during braking.
    The sledge 1 comprises a braking device 12 arranged to operate the rear runners 5c, d to be directed inwards (inwards relative to the normal direction of travel N) when braking such as plow braking is performed. The brake device 12 comprises a brake release link, or some other means (not shown) arranged to pull the guide plate (compare FIG. 2) forward to pull the guide links 4h forwards and inwards by means of the link arms 4i (seen in relation to the normal direction of travel N).
    The brake release link can be attached to a brake lever, or a brake pedal.
    Referring now to FIG. 7, which shows a perspective view from below of a sledge 1 with a braking device 12 according to an alternative embodiment of the invention.
    According to a further alternative embodiment of the invention, the front runners 5a, b may comprise a braking device 12. The braking device 12 has a plow-shaped profile arranged at a rear part 5a 'of said at least one front one with 5a, b so that a user can press the braking device against the surface by its foot. The plow brake 12 is similar to old snow plows, where a central line divides snow and transports the snow outwards. In this way, the brake is not blocked by snow, which otherwise impairs its function. The plow-shaped brake 12 may be made of the same material as the med and integrated with it, but may also be made separately to the same or of other material and fastened by means of conventional fastening elements such as screws. In light of this embodiment, the rider or runners with the brake 12 are typically made of more elastic plastic than the other components because the user pushes the rear portions down using his heel.
    By means of the plow brake 12, the braking effect is considerably improved compared to conventional technology by utilizing plow braking in relation to conventional brakes for sledges which do not use the front runners for braking. In addition, the design of the brake is greatly simplified compared to conventional mechanical brake mechanisms which require a number of mechanical links and other brake components, which can be complicated and expensive to manufacture.
    The embodiments shown in FIG. 7 also has some other control components. The front guide components include front guide links 4g, f, which may be ball joints attached to the front link arms 4d which are longitudinally adjustable as shown. The front link arms 4d are attached to the front guide plate 4e, which is attached to the guide shaft 4c. The rear guide links 4h can also be ball joints attached to rear link arms 4i which are adjustable in length. Other forms of the brakes, such as a number of extending pins, are also conceivable instead without departing from the uptake.
    According to an alternative embodiment of the invention (not shown), the vehicle has three slides, the rear slides d being arranged to provide control on a surface. The front sleeve can be designed without control on the same as in a conventional bobsled sled.
    According to a further embodiment of the invention (not shown), the steering wheel can be arranged so that the rear runners 5c, d can be steered by means of the steering wheel instead of by the seat.
    The invention is not limited to the preferred embodiments described above. Various alternatives, modifications and equivalents can be used. Therefore, the above embodiments should not be construed as limiting the scope of the invention, which is defined by the appended claims.
