FR2713578A3 - Handhold structure for e.g. motorcycle handgrip or vehicle steering wheel - Google Patents

Abstract

The handhold structure comprises at least an elongated tubular member, made of a suitable material, mounted on a steering wheel or handgrip. A number of projections, made of a suitable material, are uniformly distributed on the tubular member. The projections are formed in a shape having a rounded top end to contact and massage to hand holding the handhold structure. A longitudinal slit extending along the length of the tubular member and is used for mounting the tubular member to the steering wheel. An opening formed on an end of the tubular allows the tubular member to be fit over the handgrip.

Description

The invention relates generally to an envelope structure

  operating member such as a motorcycle handle or a motor vehicle steering wheel, and in particular an envelope structure having hand massage reliefs, intended to massage the hand holding the envelope

  lop when driving the motorcycle or car.

  Driving for a long time is a very tiring task. For professional long-distance drivers, relaxation of both physical and mental tensions is absolutely necessary after a long driving period to subsequently ensure

driving safely.

  It is therefore advantageous to produce an envelope structure for an automobile steering wheel or a motorcycle handlebar, which comprises several reliefs intended to contact and massage the muscles of the hand which holds it, in order to release the muscular tension due to a long duration of contraction. The present invention thus relates to an envelope structure for a motor vehicle steering wheel or two-wheel vehicle handle, which comprises several rounded reliefs of suitable size and / or shape, formed on a tubular element mounted on the steering wheel or the handle so as to contact and thus massage the hand (s) holding the

steering wheel.

  In particular, the reliefs will have a desired shape with rounded end, such as an arcuate, hemispherical, semi-ellipsoidal or conical shape with round end, these reliefs being preferably distributed uniformly to contact and massage the hand or hands holding the envelope. Other objectives and advantages of the invention

  will appear on reading the following description of modes

  preferred embodiments of the invention in correspondence with the attached figures, o: - Figure 1 is a perspective view showing a first embodiment of the invention on which is shown an automobile steering wheel fitted with a envelope according to the invention; - Figure 2 is a perspective view of a second embodiment of the invention, on which is shown an automobile steering wheel of another type equipped with an envelope according to the invention; - Figure 3 is a sectional view showing the structure of the automobile steering wheel of Figure 1 or 2; Figure 4 is a perspective view showing a third embodiment of the invention, on which is shown a motorcycle or bicycle handle envelope structure according to the invention; and - Figure 5 is a sectional view of the motorcycle or bicycle handle equipped with the casing structure

according to figure 4.

  With reference to the figures and in particular to Figures 1 and 3, o a first embodiment of the

  operating device shell structure 10 according to the invention

  tion usable with a car steering wheel 40 is shown, the envelope structure of the operating member 10 of the invention comprises an elongated tubular element 11 formed so as to be mounted on a steering wheel. Several reliefs or protrusions 12, of desired shapes and / or sizes, provided with ends

  rounded, are uniformly distributed over the external surface

  of the tubular element 11 to contact and massage a

  hand 90 (see Figure 3) gripping the handwheel 40.

  The suitable forms of the reliefs 12 can be semi-cylindrical, hemispherical, semi-ellipsoidal or conical with a rounded end. Other shapes with one end

  may also be used.

  Preferably, the tubular element 11 and the reliefs 12 are produced from a flexible material of suitable elasticity, in a single block. This material can be

rubber or plastic.

  In this case, the tubular element 11 comprises an elongated slot 13 formed along the latter, allowing the adaptation of the tubular element 11 to different flywheels 40. In FIG. 2, a second embodiment of the invention is presented. It is an application of the operating member shell structure, designated by the reference 20, to a steering wheel 50 of another type comprising two separate segments 51 and 52. In this embodiment, the operating device shell structure 20 of the invention comprises two tubular elements 21 and 22 mounted on the two segments 51 and 52, each of the tubular elements 21 and 22 comprising several rounded reliefs 23 having the same structure as the reliefs 12 of the first embodiment shown in Figures 1 and 3, and uniformly distributed. The sectional view of Figure 3 is obviously also applicable to the second embodiment shown in Figure 2. The invention can also be used on a

  motorcycle or bicycle handle (not shown),

  mement to the third embodiment shown on the

Figures 4 and 5.

  In accordance with these figures, the envelope structure

  actuator body lobe, designated by the reference 60, comprises a tubular element 31 having an open end 32 allowing a fitting on a handle 30 of a motorcycle or

  bicycle. Several reliefs 33 having desired shapes

  tees, such as those described above, are uniform

  evenly distributed on the tubular element 31 such that, by grasping the envelope structure of the operating member 60 of the invention, the hand 90 ′ is contacted and

  massed by rounded reliefs 33.

  Of course, even if the invention has been described in correspondence with the preferred embodiments, those skilled in the art can make changes to certain details of the preferred embodiments, without

  deviate from the spirit and scope of the invention.
