Description

Name: surfboard scooter

Description: The invention relates to a surfboard scooter, consisting from a frame provided with wheels.

Since it is usually not possible to use the motor vehicle directly To drive to a lakeshore, a surfboard and its accessories often still have to be be transported over a relatively long distance before being launched into the water can be. Both because of the dimensions and because of the relatively high With a weight of about 30 kg, this causes some difficulties, especially in many cases access to the water due to the nature of the soil (sand, scree meadow or the like) is relatively impassable. Because of these conditions, a significant Relief result if the surfboard is provided with a chassis in this way can be, such a chassis because of the heavy weight must have a high dimensional stiffness with a low dead weight and also save space must be collapsible.

They are small ones with two wheels for transporting paddle boats provided frames known that by means of straps in the area of the boat bow with the Paddle boats were connected so that the paddle boat pushed or pulled over land could be. However, these known transport racks are for the transport of a Surfboard because of its much larger dimensions and its much larger Unsuitable weight.

The invention is therefore based on the object of a surfboard scooter to create that with low dead weight and high dimensional rigidity even on difficult A comfortable transport of a surfboard is permitted on the terrain.

This object is achieved according to the invention in that the frame consists of two frame-shaped frame parts, both with one side through one common axis connected to each other and pivotable about this against each other formed and on its (upper) side facing away from the axis by at least one flexible connecting means are connected to each other that at least one frame part with a stand is provided and that the wheels with a wide Tread are provided. A surfboard scooter designed in this way has a row of advantages. Due to the pivotable connection of the two frame-shaped Frame parts these can be folded flat so that the scooter itself can be easily transported. Due to the arrangement of the flexible connecting means The surfboard scooter can easily be placed between the two frame parts by unfolding the two frame-shaped frame parts ready for operation move, as no special assembly measures are required. By the arrangement a stand can be the surfboard scooter according to the invention in the unfolded state stand upright despite the arrangement of only two wheels, d. H. so in working order State so that it can be loaded without another Person needs to hold the surfboard scooter during the loading process. The order of wheels with a wide tread gives the surfboard scooter when loaded good rolling properties, so that the surfboard despite its relatively high weight even in poor soil conditions, such as sand, gravel, scree, moist meadow soil, can be transported easily.

In a preferred embodiment of the invention is provided see, that the first frame part is designed as a closed frame, with one frame side forms the axis and has lateral extensions and that the second frame part is bow-shaped and with its two free ends with the lateral Extensions of the first frame part is pivotally connected and that the wheels-on the lateral extensions of the first frame part are stored. This frame shape offers a high degree of stiffness with low weight and allows the surfboard scooter fold flat. In addition, this offers a particularly simple frame shape the advantage of simple and inexpensive manufacture.

In an advantageous embodiment of the invention it is provided that the The (upper) sides of both frame parts facing away from the axis are trough-shaped are. Because of the large lever arm that acts on the surfboard scooter when it is in place This results in surfboard between surfboard scooter and surfboard, supported due to the relatively high weight of the surfboard, practically a "form-fitting" Connection between the two parts so that the fastening straps that hold the surfboard is lashed to the surfboard roller, should not be subjected to excessive stress.

It is particularly advantageous if the two frame parts the end Pipes are produced, as this creates a particularly favorable ratio between Weight, resilience and dimensional stability is given.

In an advantageous embodiment of the invention, it is also provided that the flexible connecting means by a belt, preferably made of textile material is formed.

In a further advantageous embodiment of the invention, there are two Straps are provided, each on the raised corner areas of the upper sides of the frame parts and are attached to cross each other. As a result, the two lie Crossing straps with an unloaded surfboard Rolley in one level that is above which is defined by the top two sides of the frame. Will Now put the surfboard on, so the two crossing straps are down pressed and at the same time the two upper sides of the frame parts slightly against each other emotional.

As soon as the surfboard rests firmly in the hollow, this results a firm tension, as the two straps are under tension. As soon as that Surfboard with the surfboard scooter using appropriate fastening straps is connected, the result is a very dimensionally stable and easy to maneuver unit, especially because of the large effective lever arm between the surfboard scooter on the one hand and the free to wear the end of the surfboard on the other hand is of great importance.

In an advantageous further embodiment of the invention it is provided that on the upper sides of the two frame parts in the support area for the surfboard elastic support pieces are arranged. Such support pieces from an elastic Materials such as rubber, plastic or the like not only protect the sensitive ones Surface of the surfboard against scratching, but also improve through this static friction to be achieved is the stiffness of the connection between the surfboard roller and a surfboard.

It is particularly useful if a frame part with a tubular Sleeve is provided in which a stator rod can be displaced and secured with securing means is kept determinable.

The invention is based on schematic drawings of an embodiment explained in more detail. 1 shows a side view of a surfboard scooter; Fig. 2 is a front view; Fig. 3 is a plan view.

Like the views of the exemplary embodiment shown in FIGS. 1, 2 and 3 can be seen, the surfboard roller consists essentially of two frame-shaped Frame parts 1 and 2. The first frame part 1 is closed by a Frame formed, the lower frame side 3 has lateral extensions 4. The second frame part 2 is essentially bow-shaped and at its both free ends with sleeves 5 firmly connected to the extensions 4 of the Frame side 3 of the first frame part 1 are pushed on. Because of this arrangement the two frame parts can be pivoted against one another in the direction of the double arrows 6, 7 will. In addition, there are wheels 8 on the extensions 4 of the first frame part pushed on and fastened with appropriate securing means. The wheels are expediently with pneumatic tires and should have as wide a running surface as possible. Wheels with the dimensions 260 x 85 are particularly cheap. When choosing the diameter the wheels a compromise must be made, as for unfavorable soil conditions The largest possible diameter are advantageous, while for the transport of the surfboard scooter Wheel diameters as small as possible are desirable in the folded state.

As the plan view in Fig. 3 shows, the upper sides 9, 10 of the two frame parts 1, 2 inserted in a trough-shaped manner to support the surfboard. At the corner areas of both of them that are created in this way and that stand up in relation to the trough Frame parts are flexible connecting means 11, 12 attached, which in the illustrated Embodiment attached crossing each other at opposite corners are. In the support area of the upper sides of the two frame parts are also elastic support pieces 13 are arranged.

Preferably on the frame-shaped frame part 1 is also in a sleeve 14 is attached to a corner area, in which a stand bar 15 can be displaced and is held fixable with securing means not shown in detail. To the When loaded, the stand bar 15 is pushed down in the sleeve 14 and through the Securing means, for example a pin, a clamping screw or the like set so that the scooter can stand freely in the position shown in FIG. After loading and lashing the surfboard on the surfboard scooter Belts not shown in detail, the securing means is released and the stand rod 15 shifted so far up and fixed again by the securing means, that there is sufficient ground clearance to move the surfboard.

With regard to the dimensions, the specified wheel size of 260 x 85 a track width of about 700 mm is considered appropriate. The overall width of the frame at the top should be about 800 mm, so that the laid Surfboard is held securely and is still within the track width of the wheels. With a total height of around 600 to 700 mm, there is sufficient security against tipping over given. In addition, the surfboard can be handled well at this height, with sufficient "ground clearance" for the mast boom, even on hilly terrain results.
