Abstract

The invention relates to a skateboard comprising a board (1) and a pair of supports (3) that are each equipped with a pair of wheels (2), wherein each support (3) can tilt vertically and horizontally with respect to the board (1). Each of the supports (3) is coupled to the board (1) preferably by means of a ball joint (7) which is solidly connected to the board (1) and housed in a cavity (4) provided in the support (3). The skateboard is easier to handle than skateboards currently available, since the wheels can easily adapt to curved paths and uneven surfaces.

Description

Roller skate.

The present invention relates to a skate, whose wheels are tilting vertically and horizontally with respect to The skate board.

Background of the invention

The skates known today are mainly of two types, with the wheels in line and two wheels Front and two rear wheels.

The skates with four wheels, two front and two rear have more stability than inline skates and it traditionally used, for example in sports such as hockey skates or figure skating.

Current skates comprise a table in whose lower part the wheels are fixed. For the placement of skate by the user, the skate may comprise a boot solidarity with said table or it can be placed by straps and you close

The main drawback of skates currently known is that its wheels are not tilting, of so that its handling can be complicated, especially for beginners and does not adapt to the irregular terrain on the That skates.

Therefore, the need for a skate that is easier to handle, and also that in its position of Transport occupies a small space.

Description of the invention

With the skate of the invention are achieved solve the aforementioned problems, presenting other advantages that They will be described.

The skate of the present invention comprises a table and a pair of supports, each support being provided with a pair of wheels, and is characterized by the fact that each support is tilting vertically and horizontally with respect to said table.

Thanks to this feature, the skate of the present invention is easier to handle than known skates currently, since the wheels can easily adapt to curved paths and irregularities in the terrain. In addition, this tilt also allows the center of gravity of the skate to the present invention may be lower, increasing its stability.

Advantageously, the coupling between said table and each of the supports is made by a ball joint in solidarity with said table that is housed inside a cavity provided on said support.

Furthermore, said table preferably comprises a pair of projections, each of which is housed in a hole complementary provided in each of said supports, to control the tilting movement of each support with respect to the table.

Advantageously, the width of said holes Complementary is greater than the width of said projections.

Preferably, said projections extend down perpendicular to the upper surface of said table.

If desired, said table may comprise minus a folding portion. In this way, the skate of the present invention can be transported when not in use folded, occupying a small space.

Brief description of the drawings

For a better understanding of how much has been exposed Some drawings are accompanied in which, schematically and only to non-limiting example title, a case study of realization.

Description of a preferred embodiment

As can be seen in the figures, the skate of the present invention comprises a table 1 provided with four wheels 2, two front wheels and two rear wheels.

Rear wheels 2 and front wheels 2 they are joined together by a support 3, which in turn is coupled to said table 1.

The coupling between each support 3 and the table 1 is performed so that the support 3 can swing horizontally and vertically

In the embodiment shown, the coupling between table 1 and brackets 3 it is carried out using a ball joint 7 in solidarity with said table 1 which is housed in a complementary cavity 4 provided for said support 3.

In addition, table 1 also includes in its ends a protrusion 5, which extends downward perpendicular with respect to the upper surface of table 1. This projection 5 is it lodges in a hole 6 present in each support 3.

The dimensions of said hole 6 are larger that the dimensions defined by the cross section of said projection 5, as can be seen in figure 5. Of this way, said projection 5 can slide slightly inside of said hole 6.

It should be noted that the tilt movement of the supports 3 with respect to table 1 will be limited by this movement of the projection 5 inside said hole 6. Thus, as can be seen in figure 5, the movement of tilting will be reduced, but sufficient for the purpose intended by the skate of the present invention.

The presence of the kneecap 7 allows the support 3 can swing freely horizontally and vertically to the same time, so that the wheels 2 of the skate of the present invention may be rotated with respect to table 1 of the skate for take a curve, for example, and also inclined with respect to the skateboard table 1, for example to adapt to irregularities of the terrain on which it skates.

This tilt movement also allows lower the center of gravity of the skate, increasing its stability.

In the embodiment represented in the figures the skate of the present invention is formed by two pieces articulated with each other, defining a folding portion 1a, so that in its folded position (figure 6), the skate of the present The invention occupies a small space, facilitating its transport.

Preferably, said folding portion 1a is articulated with respect to the rest of table 1 by an axis of cross joint 8.

Although reference has been made to a Concrete embodiment of the invention is evident to an expert in the matter that the skate described is susceptible to numerous variations and modifications, and that all the details mentioned they can be replaced by technically equivalent ones, without depart from the scope of protection defined by the claims attached.

For example, it should be noted that you can insert an elastic shock absorber between the kneecap and the board to control the hardness and the turning path of the wheels.
