Description

Blade paddle.

Object of the invention

The present invention relates to a shovel of paddle, which has very structural characteristics individuals based on the independence of the different parties that constitute the whole of the shovel, allowing the user effect the change and / or replacement of any of them, as well how to establish combinations between them.

The object of the invention is to be able to change in any time the part that constitutes the driving core of the shovel with respect to the frame, as well as being able to make the combinations You want between the frame and the aforementioned drive core.

Background of the invention

Paddle blades are manufactured in such a way which generally constitute a monobloc body, which prevents replacement or replacement of its parts, in case of breakage and / or deterioration of any of them, or simply in those cases in which the user wants to make a change and form different combinations between the two fundamental parts of the shovel, such as the frame and the driving core.

In short, in conventional blades that they are manufactured for the practice of paddle, when the frame or the part that constitutes the driving core, is it is necessary to change the entire blade, which means a considerable expense for the user.

Description of the invention

The recommended blade has been designed to solve the problem described above, based on a Simple solution but no less effective.

Specifically, the blade of the invention is characterized in that the frame and impeller core are independent parts that can be assembled and disassembled without any problem or difficulty, based on pressure joining elements, sandwiched between them and easy to assemble. manipulate to establish the frame and core fixation
driving.

The joining elements allow the user of the racket, to be able to make said frame and drive core independent and with them replace, change and / or combine these elements with each other, either because some of them has broken, due to any deterioration, etc. , or by desire or whim of the own
Username.

The frame is preferably materialized by a tube that can be of any type of suitable material, the variable being equally variable.
weight.

For its part, the drive core can also be of various types of material and of variable weight, being attached to the frame through specific areas that provide buoyancy due to the special configuration of the elements of
Union.

In addition, between frame and drive core is set small air slots, which determines that when produces the beating, the shock wave flows throughout the core, allowing temporary deformation beyond its surface, mitigating the forces to which it is subjected by the beating.

As for the elements of union, the same are regularly distributed on the contour between frame and drive core and constitute tensioners that can be rigid or semi-rigid, being materialized by pairs of bodies truncated conical faces facing each other and held by a screw, pin, rivet, etc.

As a consequence of the characteristics commented, the shovel as a whole offers physical properties or different mechanics, as resistance or breakage torsion and flexibility.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows a representation according to an overview of a paddle shovel made according for the purpose of the present invention.

Figure 2.- Shows a perspective view of the frame corresponding to the blade represented in the figure previous, with the elements of union, being this racket devoid of the drive core.

Figure 3.- Shows a sectional view transversal at the level of one of the joining elements individualized

Preferred Embodiment of the Invention

As you can see in the referred figures, the blade of the invention comprises three mountable fundamental parts and detachable from each other. One of the parties is the corresponding frame (1) with its mooring handle (2), frame that is tubular and of an appropriate material.

The second part is the core impeller (3) that is inscribed in the frame (1), being able to also be constituted in diverse materials. Said drive core (3) has the corresponding perimeter flange (4) left concentric with the frame (1), as clearly seen in the figure one.

The third part is a plurality of connecting elements (5) tension determining factors that can be rigid or semi-rigid. In any case, said connecting elements (5) provide the drive core (3) with a buoyancy character in its assembly on the frame (1) of the racket, said core remaining impeller (3) mounted with point supports through said joining elements (5).

As can be seen in figures 2 and 3, the aforementioned joining elements (5) have a configuration determined by two trunk-conical parts facing one of their smaller bases, where the lateral surface of said trunk-conical parts rest on small concave depressions established for this purpose both inside the frame (1) and the outer flange part (4) of the core
impeller (3).

The commented elements of union, or better said the pair of conical trunk parts that form each of they establish pressure when they are mounted in the zones corresponding, between the frame (1) and the drive core (3), fixing each pair of those parts together conical trunk by means of a pin, screw or similar, through a hole (6) established in each of they.

In the case of fixing screws, You can easily assemble / disassemble quickly and easily, while when it comes to pins with prisoner, then the assembly will also be carried out quickly and easily, although in this case for disassembly it is necessary to break the joint and replace it with a new kit, logically, using both parts  conical trunk and the corresponding pin.

Claims (4)

1. Paddle paddle, characterized in that it comprises a frame, a driving core and a plurality of pressure joining elements that establish respective specific joint supports between the frame and the driving core, with the particularity that such joining elements allow for independence and corresponding change and / or combination of frame and drive core. 2. Paddle blade, according to claim 1, characterized in that the connecting elements determine rigid or semi-rigid tensioners and are constituted by two trunk-conical parts facing their smaller bases, and affected by an orifice for an anchoring pin, such as a screw, stud or similar. 3. Paddle blade, according to previous claims, characterized in that a plurality of concave depressions are provided on the internal part of the frame and external part of the perimeter flange of the drive core for supporting the lateral surface of the connecting elements, the subject being held drive core on the frame with floating character. 4. Paddle paddle, according to previous claims, characterized in that air slots are determined between the frame and the perimeter edge of the driving core that allow the temporary deformation of the driving core in the striking to minimize the stresses to which it is subjected.
