Description

DESCRIPTION

WHEEL FOR SKATEBOARD AND SKATEBOARD

TECHNICAL SECTOR

The enunciated invention falls within the sector of the wheels used in the means of movement intended for personal mobility generated by the user's own effort.

Specifying the sector more specifically, the enunciated invention falls within the field of the wheels used in the aforementioned purpose and whose force generated for the displacement of the medium is carried out by the impulse of the user himself.

STATE OF THE ART

As a reference to the current state of the art, and in the specific sector mentioned above, it should be noted that the inventor knows different types of wheel used specifically in skateboards or scooters.

Although the concept composition is the same for both vehicles with respect to the wheels, a vertical rotating disk installed on a fixed horizontal axis, it should be mentioned that the composition of basic elements in them currently varies substantially between both models.

In the case of skateboards, the current composition of the wheels is based on a generally solid disk, and of considerable width, with a bearing inside which is coupled to an axle. Said composition is the product of the configuration of the vehicle, as it is made up of a wide platform with two front wheels and two rear wheels placed in parallel.

In the case of scooters, the current composition of the wheels is based on a rim mounted on a rim which in turn is coupled to an axle, the vehicle configuration being formed by a narrow platform which has one or two front wheels steerable by the user by means of a handlebar and a rear wheel.

With regard to the stated invention, the composition of the wheels, and with reference to the above, at least the inventor does not know the existence of any wheel with a similar composition and functionality intended for skateboard and scooter vehicles.

OBJECT OF THE INVENTION

As stated in the state of the art, skateboards and scooters are means of movement driven by the user himself by placing a foot on the ground.

Its mission is to take advantage of completely smooth surfaces, without bumps or bumps, to be able to maintain a constant speed.

In general, they tend to travel on firm surfaces without unevenness, and in the case of having unevenness that this is in descent, since on the rise the impulse is more expensive and the advance is minimal, the user having to carry the vehicle in the hands.

It is precisely in the descent where these vehicles present disadvantages, especially in the youngest users, since they lack experience to be able to slow down and thus avoid accidents.

In the field of scooters today there are some models which have a means of braking, either on the grip or on the back of the platform near the wheel, but the vast majority and especially on skateboards do not It has no means of braking.

The fact that scooters do not have any braking means is usually a matter of simplicity in functionality and a matter of originality.

In the case of skateboards, the issue is obvious, said vehicle lacks spaces for the installation of a brake actuator and for its coupling to the wheels.

It is for this reason that the enunciated invention is presented, solving said drawbacks and in turn respecting the design and originality of said vehicles.

For this purpose, the enunciated invention provides a wheel which has an integrated system of gradual speed regulation which acts without having to manually actuate any mechanical element.

DESCRIPTION OF THE INVENTION

Thus, the wheel for skateboard and scooter that the invention proposes is configured as a remarkable novelty within its field of application, the characterizing details that make it possible and that distinguish it from what is known today are conveniently collected in the indications that accompany the present description.

Specifically, what the invention proposes as previously stated is a wheel which prevents the vehicle from reaching risky speeds without having to actuate any element by the user.

The technique used for this purpose is based on the principle of eddy current or eddy current, which comes to say in a summarized way that as a circular metal plate moves through a region of constant magnetic field, with the same opposing magnetic poles, said plate tends to be retained product of the concentration of said magnetic field in the plate as a consequence of its deformation due to the confrontation of the poles.

In the case of the stated invention, said principle is applied, with the exception that the constant magnetic field is the one that moves when the circular metal plate is stopped.

Thus, and with the previous introduction made, the enunciated wheel consists of two halves joined together on the internal face of which and confronted with each other through the same poles a series of permanent magnets are arranged. Said permanent magnets are arranged individually in pieces, around the bearing, with the poles facing each other, and where both halves are placed in such a way that the magnets are placed interspersed between existing gaps.

Said joined halves make up a single wheel, and which in turn are coupled by means of separate bearings to the axle of the skateboard or scooter. In order to apply the above principle, both halves are separated inside by a low conductivity metal disc, preferably aluminum, which is kept fixed to the axis of the skateboard or scooter.

In order to be able to set the turning speed of the wheel based on the speed that the vehicle could reach, a non-metallic separating washer of a certain thickness is arranged between one of the halves that house the magnets and the metal disc.

The fact of having a magnetic field inside a wheel can lead to the adhesion of objects or metallic particles on the outside of it, specifically on the tread, a fact which could make it difficult for the vehicle to move forward. To avoid such inconvenience, there is a ring made of Mu-Metal material which surrounds the magnets and serves as an external shield for the magnetic field.

In this way, when the vehicle should reach a high speed as a result of a steep descent, the wheels themselves generate a lower vehicle speed which allows the user to control it better.

DESCRIPTION OF A PREFERRED EMBODIMENT

With reference to the attached figures, taking into account the numbering reflected therein, and in a preferred and non-limiting embodiment, the wheel for skateboards and scooters is made up of two vertical sections (1 and 1 ') with identical configuration joined between Yes.

The internal face (11 and 11 ') of each section (1 and 1') has a series of permanent magnets (12 and 12 ') arranged around a hole (13 and 13'), sandwiched between holes ( 15 and 15 '), and which houses a bearing (14 and 14') to be coupled to the shaft (4) of a skateboard or scooter, with the permanent magnets (12 and 12 ') facing each other by the same poles when the wheel is shaped.

Between both sections (1 and 1 ') and fixed to the shaft (4), a low conductivity metal disc (2) is arranged, preferably made of aluminum, not ruling out other metals with said properties.

Placed between the metal disc (2) and one of the sections (1 or 1 ') a non-metallic washer (3) is arranged, and surrounding the magnets there is a ring (16 and 16') made of Mu-Metal material with shielding functions for magnetic field.
