HANDLEBAR ANTIVIBRATIONS FOR BIKES AND SIMILAR VEHICLES

D E S C R I P C I O N

OBJECT OF THE INVENTION

The invention, as expressed in the statement of the present specification, refers to an antivibration handlebar for bicycles and similar vehicles that provides, to the function to which it is intended, advantages and characteristics, which are described in detail below, which assume an improvement of the current state of the art.

More specifically, the object of the invention is centered on a handlebar which, formed from a tubular part applicable to grip with hands and guide bicycles and other similar two-wheeled vehicles, has the particularity of having an improved structural configuration that provides vibration absorption means, which are specially studied in their configuration and arrangement to avoid or minimize to the maximum the effect that the vibrations produced by the irregularities of the ground in the arms of the user that hold it while driving can produce.

FIELD OF APPLICATION OF THE INVENTION

The field of application of the present invention is part of the sector of the industry dedicated to the manufacture of bicycles and similar vehicles, focusing particularly on the field of tube handlebars.

BACKGROUND OF THE INVENTION

As is known, bicycles and many other similar vehicles, usually two-wheeled, are usually handled with a handlebar formed simply from a metal tube bar that is attached directly to the chassis of the vehicle.

Therefore, the driving and handling of such vehicles, especially mountain bikes, but also others such as motorcycles or similar, depending on the type of terrain through which they pass and dependent on time, produce vibrations that, through the handlebar bar, impact on the arms can be very annoying; so much that, They may end up desensitizing the hands of the cyclist, with the corresponding risk of not responding adequately to a need to stop or other unforeseen action.

The object of the present invention is, therefore, to provide an improved type of tube handlebar for bicycles and other vehicles incorporating this type of handlebars, whose structure avoids or minimizes the action of such vibrations by interposing elements of absorption thereof. .

On the other hand, and as a reference to the current state of the art, it should be noted that, at least on the part of the applicant, the existence of no other handlebar that presents technical, structural and constituent characteristics that are the same or similar to those presented the one that is claimed here.

EXPLANATION OF THE INVENTION

The antivibration handlebars for bicycles and similar vehicles proposed by the invention makes it possible to satisfactorily achieve the aforementioned objectives, the details that make it possible being possible and which distinguish it conveniently included in the final claims that accompany the present description.

More specifically, what the invention proposes, as pointed out above, is a tube handle that has the particularity of having an improved structural configuration that provides means of absorbing the vibrations caused by irregularities of the ground on the arms of who handles it when circulating, which means of absorption are specially studied in their configuration and arrangement to avoid or minimize the effect of said vibrations.

For this, and more specifically, the handlebar, which, as has been said, is a tube handlebar, is divided into three parts by two points located between the end sections destined for the grips with which it is held by the hands and the section. central, where are incorporated elastic elements to join said three parts, so that the ends with the grips do not directly receive the vibrations of the ground that affect the central section of the handlebar through which is attached to the chassis.

Preferably, said two elastic elements consist of two steel springs of a certain thickness, which can also include two ball joints, to provide the necessary firmness to the ends of the handlebar with the gripping handles.

Furthermore, in the preferred embodiment, said springs are covered by respective ferrules formed by an inner filler and an outer coating of rubber or resistant rubber, providing greater resistance to the area.

DESCRIPTION OF THE DRAWINGS

To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, the descriptive specification is attached, as an integral part thereof, of a set of drawings in which, with illustrative character and not limiting the following has been represented:

Figure number 1 shows a schematic view in perspective of an embodiment of the handlebar object of the invention, appreciating the parts and elements comprising, as well as its configuration and arrangement, failing to include the protection caps.

Figure number 2 shows a perspective view of a steel spring, as a preferred example of vibration absorbing means provided by the handlebar, according to the invention.

Figure 3 shows a perspective view of a piece of rubber with which optionally the handlebar also counts as a protection cap.

Figure number 4 shows again a perspective view of the handlebar, in this case including the protection sleeves on the springs.

Figure number 5.- Shows a perspective view of the handlebar, in this case in an option that, in addition, includes a ball joint linked to an inner adjustment bolt, coupled on each side of the handlebar.

And figure number 6.- Shows a perspective view of the bolt with the ball joint that is included in the variant of the handlebar shown in figure 5.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the aforementioned figures, and in accordance with the numbering adopted, one can observe in them an example of non-limiting embodiment of the handlebar of the invention, which comprises the parts and elements that are indicated and described in detail below.

Thus, as can be seen in said figures, the handlebar (1) in question, formed in a known manner from a substantially straight tubular body that is attached by its central area to the chassis of the vehicle and at its ends has respective handles ( 2) for its attachment, has the particularity of being divided into three parts, a central (1a) and two lateral (1b), separated from each other by two spaces (1c), located next to the end sections with the handles ( 2), where it incorporates respective elastic elements (3) that join, on each side, both lateral parts (1b) with the central part (1a), absorbing the vibrations received by said central part (1c) through the chassis when circulating.

Preferably, the two elastic elements (3) incorporated in said separation spaces (1c) are identical and consist of two steel springs.

In addition, also preferably, the elastic elements (3) are covered by respective rubber or rubber protection bushes (4), which, more specifically, are formed by an inner filler and an external rubber or rubber coating. It should be noted that in Figure 1 the handlebar has been represented without incorporating said bushes (4), while in Figure 4 its position on the handlebar on the springs can be seen.

Optionally, as shown in figures 5 and 6, the handlebar further comprises a ball joint (5) together with each elastic element (3) which is incorporated in the end of a bolt (6) that is incorporated inside the tube of the handlebar (1) threaded by its thread area (6a), serving as a means of regulating said elastic element.

In the preferred embodiment, but without limitation, since the measurements can vary from one case to another, depending on the size and type of vehicle, for a conventional adult bicycle, the length (A) presented by the spaces (1c) of the handlebar (1) in which the springs (3) are incorporated is 15 mm; the width (B) of said spaces (1c) is 20 mm; the thickness (C) of the steel of the springs (3) is 7 mm; the diameter (D) of the protection bushes (4) is 25 mm; and the distance (E) from the end of the handles (2) up to the space of separation (1c) in which the springs (3) are incorporated is 185 mm.

Having sufficiently described the nature of the present invention, as well as the way of putting it into practice, it is not considered necessary to extend its explanation so that any expert in the field understands its scope and the advantages derived therefrom, stating that, within its essentiality, it may be carried out in other forms of realization that differ in detail from that indicated by way of example, and which will also achieve the protection that is sought provided that it is not altered, changed or modified its fundamental principle .
