BE2017 / 5149

Go-kart or go-kart.

The present invention relates to a go-kart or go-kart.

More specifically, the present invention relates to a go-kart or go-kart, which is provided with a chassis on which a number of wheels are mounted, as well as a steering device with a steering wheel that can be operated by a user for controlling the go-kart or go-kart .

Such a go-kart or go-kart is usually not really intended as a means of transport, but rather is used as a toy for children or young people, where it is not the intention to travel long distances with the go-kart or the go-kart.

Furthermore, such a go-kart or go-kart is typically driven by muscle power, for example using pedals or pedals or by pushing the feet off the ground.

Nevertheless, it is not excluded that the invention may also be applied to go-karts or go-karts that do serve as real means of transport and / or go-karts or go-karts that are provided with drive means, such as an electric motor or combustion engine.

Many types of such go-karts or go-karts are already known in the prior art, but they have a number of drawbacks.

BE2017 / 5149

A major disadvantage of the well-known go-karts or go-karts is that they are quite bulky, so that a lot of space is needed to store them, for example during periods where the go-kart or go-kart is not used.

Also, the well-known go-karts or go-karts often do not fit in the trunk of a car due to their size, making them easy to transport, which is often the case, for example, when such a go-kart or go-kart is taken on holiday. as a toy for the children and the like.

Yet another drawback of the known go-karts or go-karts related to this is that their shape is very impractical for storing them in a storage cabinet or the like or for stacking several such go-karts or go-karts.

The present invention therefore aims to provide a solution to one or more of the aforementioned or possible other disadvantages.

To this end, the invention relates to a go-kart or go-kart, which is provided with a chassis on which a number of wheels are mounted, as well as a steering device with a steering wheel that can be operated by a user for controlling the go-kart or go-kart, wherein the steering wheel of the steering system of the go-kart or go-kart is designed in such a way that it is adjustable between a position of use, in which position the go-kart or go-kart can be controlled by means of the steering wheel, and a

BE2017 / 5149 storage position, in which storage position the steering wheel is in a folded or retracted position.

A major advantage of such a go-kart or go-kart according to the invention is that its steering wheel can be brought into a retracted or folded state by adjusting the go-kart or the go-kart to the storage position, so that the size of the go-kart or go-kart is severely limited in this storage position.

Accordingly, such a go-kart or go-kart according to the invention can be stored much more easily, for instance in a trunk of a car, than is the case with the known go-karts or go-karts.

In a preferred embodiment of a go-kart or go-kart according to the invention, the go-kart or go-kart is additionally or alternatively provided with at least one seat with a backrest, the backrest being arranged on the chassis by means of one or more hinge connections and is adjustable between a position of use, in which position of use the backrest is brought into an upright position, and a storage position, in which storage position the backrest is folded down.

Such a preferred embodiment of a go-kart or go-kart according to the invention is even more interesting, since even less space is required for storing it than in the first embodiment with only a folding steering wheel, since in this embodiment the go-kart or go-kart in a storage position can be brought, with the backrest also folded down,

BE2017 / 5149, so that no storage space is required for the upright backrest.

In a further preferred embodiment of a go-kart or go-kart according to the invention, the steering wheel is mounted on a steering axle which can rotate in a support tube, the steering axle extending partly from the support tube to the steering wheel and the steering axle between the steering wheel and the support tube in this section have a hinge joint that connects an upper steering axle section to a lower steering axle section.

A neat version of a go-kart or go-kart is relatively easy to manufacture, while the hinge connection not only offers great convenience and guarantees safe operation of the steering during use of the go-cart or go-kart in the operating position, but with hinge connection, the go-kart or go-kart can also be very easily brought into the storage position, whereby the steering wheel is folded down.

Most preferably, the steering device in a go-kart or go-kart according to the invention is provided with blocking means for blocking the pivot connection in the steering axle or for unlocking it.

It is of course the intention here that the hinge connection is brought into the blocked state with the aid of the blocking means when it

BE2017 / 5149 steering wheel is placed in the operating position, so that the safe operation of the steering is guaranteed.

On the other hand, if the blocking means are manipulated so that the hinge connection is brought into the unlocked state, the steering wheel can be folded down to store the go-kart or go-kart.

In a preferred embodiment of a go-kart or go-kart according to the invention, the steering device is provided with blocking means which mainly consist of a sleeve, cap or screw which, on the one hand, can be placed over the hinge connection, or on the other hand, can be removed from it or can be moved over the steering axle away from the hinge joint, respectively to lock and unlock the hinge joint.

Such an embodiment of a go-kart or go-kart according to the invention is relatively simple to implement, is easy to handle and allows an aesthetic finish of the go-kart or go-kart.

Another preferred aspect of a go-kart or go-kart according to the invention is to provide the steering wheel with an annular portion in the form of a circular arc, which is connected to the steering axle by means of radially extending portions to the steering axle.

A major advantage of such an embodiment of a go-kart or go-kart in accordance with the invention is that the steering wheel does not define a full circle, so that

BE2017 / 5149 it is possible to move the steering wheel further down in the stowed position than it would if a fully circular steering wheel was used.

This will be further illustrated in the text using figures.

According to the invention, however, it is not excluded to implement a go-kart or a go-kart with a circular steering wheel.

Another preferred aspect of a go-kart or go-kart according to the invention is to provide a tubular rail on either side of the go-kart or go-kart extending in the longitudinal direction of the go-kart or go-kart and on both sides of the backrest the go-kart or go-kart is provided with a bracket that is hinged at one end to the backrest and is slidably mounted at the other end over the corresponding tubular rail, in order to be able to move the backrest between a forward position and a backward position stand.

An advantage of this embodiment of a go-kart or go-kart according to the invention is that the distance between the steering wheel and the backrest can be easily adjusted and adjusted by sliding the respective ends of the brackets over the tubular rails.

Having the insight to better demonstrate the features of the invention is hereafter described as without limitation

BE2017 / 5149 character, describes a preferred embodiment of a go-kart or go-kart according to the invention, with reference to the accompanying figures, in which:

Figure 1 is a side view of a go-kart or go-kart according to the invention when it has been brought into the use position;

figure 2 shows in side view the go-kart or go-kart according to the invention from figure 1 when the blocking means has been brought into a non-blocking position;

figure 3 is a side view again showing the go-kart or go-kart according to the invention from figure 1 with the steering wheel folded down;

Figure 4 is a side view, finally, showing the go-kart or go-kart according to the invention from Figure 1 when it has been brought into the storage position by folding down the backrest during corrugation;

figure 5 shows in perspective a disassembled version of the steering axle, the hinge connection and the steering wheel of the go-kart or go-kart from figure 1; figure 6 shows in perspective the same parts as in figure 5 this time in assembled condition, and in the position of use of the go-kart or shelter as shown in figure 1;

figure 7 shows in perspective the assembled whole of figure 6 when the steering wheel is folded down according to the states of the go-kart or go-kart shown in figures 3 and 4; and, figures 8 and 9 illustrate in perspective how the steering axle is mounted in a support tube of the go-kart or go-kart and this respectively in a position

BE2017 / 5149 according to the positions shown in figures 6 and 7.

The go-kart according to the invention 1 shown in figures 1 to 4 is a vehicle with two pairs of wheels, a pair of front wheels 2 and a pair of rear wheels 3 respectively, which are mounted on a chassis 4 of the go-kart 1.

In the front 5 the go-cart 1 provided with a steering gear 6 by which a user of the go-cart 1 the position of the front wheels 2 from the go-cart 1 we can zzig ten relative to it chassis 4 to thus in the direction to

sets in which the go-kart or go-kart 1 moves.

As shown in more detail in Figures 8 and 9, the chassis 4 is mainly formed by a frame 7 of tubes 8 connected together.

The steering device 6 comprises a steering axle 9 which is mounted

in a slant upward and somewhat backwards oriented support tube 10 That is part of it tubular frame 7 • The steering axle 9 can röteren in the support tube 10 while the support tube 10 7. a permanent part forms of the tubular frame The lowest end 11 from the steering axle 9 sticks out the

support tube 10 and at the location of this lower end 11 the steering shaft is provided with a hook-shaped part 12.

BE2017 / 5149

With this hook-shaped part 12, a linkage connecting the front wheels 2 (and which is not further shown in the figures) can be controlled by turning the steering axle 9.

The position of the front wheels 2 with respect to the chassis 4 can thus be changed.

At the upper end 13 of the steering axle 9, a steering wheel 14 is provided with which a user can rotate the steering axle 9 in the support tube 10.

An important feature of the invention consists in that the steering wheel 14 of the steering device 6 is designed in such a way that it is adjustable between a position of use, shown in figure 1, and a storage position, which is shown in figure 4.

In the stowed position, the steering wheel 14 is in a folded down or retracted position, so that less space is needed to store the go-kart 1 than is the case with the known go-karts.

To make this possible, the steering shaft 9 extends with a part 15 from the support tube 10 to the steering wheel 14, the steering shaft 9 between the steering wheel 14 and the support tube 10 in this part 15 being provided with a hinge connection 16 which upper steering axle section 17 connects to a lower steering axle section 18.

This is shown in more detail in Figures 5 to 7.

BE2017 / 5149

The hinge connection 16 itself is adjacent to the support tube 10.

To this end, a first hinge section 19 is provided with a tens 20 which can rest on the upper end 21 of the support tube 10, while allowing a rotation of the steering shaft 9 in the support tube 10.

In another embodiment, the flange 20 can be supported in the support tube 10 by means of a bearing.

The lower steering axle section 17 is fixedly connected to the first hinge section 19.

Transversely to the flange 20, an upright flank 22 is provided which can be fitted between two flanks 23 of a second hinge portion 24 appropriately.

Transverse sections 25 are provided transversely through the flanks 22 and 23 of the first hinge section 19 and the second hinge section 24 and the first hinge section 19 and the second hinge section 24 are hinged together by means of a rivet 26 or the like which pass through these passages 25 is applied.

The second hinge section 24 further has a tubular end 27 which can be fitted in an end 28 of the upper steering axle section 17, which in this case is made hay.

BE2017 / 5149

At the other end 13 of the upper steering axle section 17, the steering wheel 14 is fixed by means of a pair of screws 29.

The steering device 6 is also provided with blocking means 30 for blocking the hinge connection 16 in the steering shaft 9 or for unblocking it, respectively with the intention of preventing or allowing the hinges of the hinge connection 16 to be allowed.

In the embodiment shown, the blocking means 30 are designed as a sleeve, cap or screw 30 which, on the one hand, can be fitted over the hinge connection 16, which is shown, for example, in Figures 1 and 6, or, on the other hand, can be moved over the steering shaft 9 away from the hinge joint 16, as shown, for example, in Figures 2 and 7.

Obviously, in the position where the screw or sleeve 30 is slid over the hinge joint 16, the Hinging of the hinge joint 16 is prevented, while in the position where the screw or sleeve 30 is moved upwardly over the upper steering shaft portion 17 and the hinge connection 16 is left free, the hinge connection 16 is released and can hinge freely.

The screw or sleeve 30 can be made of a metal on which a plastic is applied on the outside, for instance with a ribbed surface so that the outside can be easily gripped with the hands.

BE2017 / 5149

In the locked position of the hinge joint 16, shown in Figures 1 and 6, the lower steering axle section 18 and the upper steering axle section 17 extend in line with each other, the steering wheel 14 being able to function without brakes for driving the go-kart or go-kart 1.

In the unlocked position of the hinge connection 16, the upper steering axle section 17 can be tilted downwards with the steering wheel 14.

This stand is very suitable for storing the go-kart or go-kart 1.

According to the invention, the blocking means 30 may be provided with a screw or clamp which must be unscrewed or loosened to unlock the blocking means 30 and which must be screwed or fastened to block or fasten the blocking means 30.

In the embodiment shown in the figures, the steering wheel 14 further comprises an annular portion 31 in the form of a circular arc, which is connected to the steering axle 9 by means of portions 32 extending radially to the steering axle 9.

The annular portion 31 in this case is more or less semi-circular and it forms the upper portion of the steering wheel 14 when the front wheels 2 are in a position

BE2017 / 5149 corresponding to the straight ahead position.

The advantage of a neat embodiment is that the steering wheel 14 can be turned further downwards against the chassis 4 of the go-kart 1 by Hinging with the hinge connection 16, than would be the case with a fully circular steering wheel 14.

This is illustrated, for example, in Figure 4.

As is also the case in the embodiment of the figures, a go-kart or go-kart 1 according to the invention preferably comprises a seat 33 with a backrest 34, wherein in particular the backrest 34 is designed such that it is adjustable between a operating position, which is shown in figure 1, for example, and a storage position, which is shown in figure 4.

In the storage position the backrest 34 is folded down, while in the in use position the backrest 34 is raised to an upright position.

To make this possible, the backrest 34 is mounted on the chassis 4 by means of hinge connections 35.

More specifically, in the example shown, a tubular rail 36 is provided on either side of the go-kart or go-kart 1, which extends in the longitudinal direction of the go-kart or go-kart 1, and a bracket 37 is provided on either side of the backrest 34, which one end 38 is hingedly connected to the backrest 34 on site

BE2017 / 5149 of the hinge joints 35 and with the other end 39 slidably arranged over the corresponding tubular rail 36.

Thus, the backrest 34 can be moved between a forward position and a backward position.

It is preferably ensured that the backrest 34 can only be rotated by a certain angular rotation.

To this end, the hinge connections 35 on the backrest 34 can be provided with one or more limiters which limit the rotation of the backrest 34 in the hinge connection 35 to the aforementioned angular rotation.

Additionally or alternatively, the backrest 34 may be formed in such a way that its rotation relative to the chassis 4 is limited to the aforementioned angular rotation.

The present invention is by no means limited to the exemplary embodiments of a go-kart or go-kart 1 according to the invention, but such go-kart or go-kart 1 can be made in many shapes and sizes without departing from the scope of the invention.
