Abstract

This invention serves in the field of water sports and recreational sports as an additional offer for physical strength-powered locomotion on SUP or surfboards. It is an easily transportable and easy to assemble box without additional tools, which after opening contains its own pedal boat mechanism with paddle wheels or drive screws . The mechanism can be put into operation by anyone with a few simple steps. This box does not affect the standard functions of a SUP or surfboard.

Description

This invention, the "flexibly mountable pedal boat mechanism" is a new, fun way of getting around on commercially available standard boards for water sports and recreational sports. It will serve to be able to use a SUP board or a surfboard at any time as a "pedal boat board" or as a simple "sailing board".

problem

Previous drive systems of this type for stand-up paddling board and surfboards are mostly firmly integrated mechanisms that intervene in the board itself. In other words, the systems are fastened or integrated in such a way that the board itself has to be machined, ie cut or drilled. In some cases, the boards can then no longer be used for their original purpose. Inflatable boards cannot be converted.
The systems are all bulky and not easy to transport.

solution

The fun box can now be mounted on any board as an independent element without having to change or destroy anything on the board. It can be easily assembled and disassembled again. It can be used on any board.
The mechanism can be folded up in a small space. The entire box is easy to transport with its dimensions of approx. 60x70x20 cm and a weight of approx. 5 kg. Furthermore, you can quickly switch from the paddling or surfing function to the “pedal boat mechanism” and back again at any time.

Function description

The flexibility is that before use, ie the entry into the water, a function box (fun box) is placed in the front area of the board, from which the desired functions (sailing or pedal boat) can be folded out at any time.
We give the athlete the opportunity to change the "drive type" at any time, even on the water.

The fun box is fixed firmly and non-slip by means of two elastic straps that are guided under the board. Due to the elasticity of the straps, no great effort is required. The straps on the underside of the board do not affect the handling characteristics of the board. (see drawing 1 and 2 )

Pedal boat function

The following steps can be carried out on the bank / jetty but also while sitting while using the board on the water with a few simple steps.
For the pedal boat function, the lid ( 2 ) the fun box ( 1 ) removed. The paddle wheels now visible from above ( 3 ) are removed and attached to both ends of the force axis ( 5 ) attached and locked. The blade plates ( 4th ) are inserted into the slots provided on the paddle wheels. The pedal axis ( 6 ) is folded up with one hand until the counter braces ( 7th ) are folded out and clamped into the fastening clip. The pedal function is ready. (see drawing 1 and 3 )
The pedal axis is operated via non-slip pedals. The transmission to the power axis, at both ends of which the paddle wheels are attached, takes place openly via a belt function with belt pulleys.

As an alternative to the drive via the paddle wheels, it can also be driven via propellers, which are also driven via the pedal function with the aid of a deflection gear. The screws are also located on both sides of the board (see also drawing no. 6)

The lid of the fun box can now be used as a seat back.

The support struts ( 11 ) expanded. On a cross brace ( 12 ) between the support bars is a seat mat ( 13 ) rolled up, which is pulled forward under the backrest part, whereby the entire construction is stable and does not slip. (see drawing 5 )

The two oars are removed from the fun box and inserted into the holes provided on the side of the fun box. The operation / control takes place via a rope. This is held loosely for driving straight ahead; depending on the direction you want, you pull left or right.

Sailing function

A functional unit that acts as a sailing mast is integrated in the fun box.
The mast is removed; the pull-out elements are extended to a height of approx. 2.00 m and the large boom is unfolded. Then the light sail is rolled up, which is pulled up on the mast and fastened at the top. In the lid of the fun box and in the bottom of the same there are mounting holes into which the mast is inserted.
The large tree is moved according to the wind via a handlebar attached to the end of the same. The rudder function is used with the other hand.

Special features / advantages achieved

The drive pulleys can be changed so that different speeds or power transmissions can be achieved with different gear ratios.

The force and the speed can also be varied by choosing different blade plates.

The fun box can be used on every type of board due to the pull-out power axis, i.e. Boards with different shapes and widths can be used.

In an alternative variant, two belt drives can be selected instead of the central drive. These then sit in the edge area directly next to the paddle wheels.

The seat function can also be used individually, e.g. when paddling the board. The seat on land can also be used as a lounger or reading chair.

The fun box can also be used on surfboards. In order to ensure stability on the slight curvature of the surfboards on the top, a preformed soft pad is fixed under the fun box before assembly.

The lid and the box are made of floatable materials and coated with synthetic resin. Metal parts are made of aluminum or stainless steel. All parts are suitable for water and salt water.

The shape of the fun box will be adapted to the rounded and dynamic appearance of the surf and SUP boards in the further development.

The "Fun-Box" is therefore an easily mountable additional element for a standard board, which can be taken and used at any time. If it is not used after all, the original functions of the board are possible at any time - even with the "Fun Box" attached - without restriction.

Claims (1)

Mobile, independent, ie not permanently connected to the Sup-Board or Surf-Board pedal function mechanism for the body-operated drive of SUP boards and surf boards, characterized by the following features: 1. The function mechanism can be folded up in a very small space in its own box and easily portable. 2. The box with the stored mechanism (the fun box) allows unhindered use of the board for its actual purpose when unopened; ie the SUP board can be used for stand-up paddling and the surf board can also be used for surfing. 3. The box with the integrated mechanism is easy to attach to a board and fasten without damaging this board. 4. The folded pedal boat mechanism is easy to fold out and can be used quickly after attaching the paddle wheels or the drive screws. 5. The cover to be removed can be used independently as a seat, also outside of the boat function. 6. By using different sizes of gear wheels, different forces can be transmitted to the paddle wheels, which are also variable in size. 7. The rudder stored in the function box can be mounted in the seated position and used for both the sailing and pedal boat functions for manual control. 8. A separate mast, which is stored in the function box, can be removed, extended and inserted into the box from above and used as a sailing mast. 9. All functions can be carried out and operated easily and without tools from the board in the water.
