FR2580553A1 - INNER TIRE WITHOUT INTERNAL BELT AND TOOTHED WHEEL ADJUSTMENT DEVICE FOR SAID BELT FOR EXAMPLE FOR BICYCLE - Google Patents

Abstract

THE TIRE, IN PARTICULAR FOR BICYCLES, IS CHARACTERIZED IN THAT IT INCLUDES AN INTERNAL VAULTED CAVITY 1 AND PRESENTING A SURFACE APPROXIMATELY FIFTY PERCENT OF THE TOTAL SURFACE OF THE INSIDE AND OUTER TIRE. A CUSHIONING AND FLEXIBILITY EFFECT WHEN RIDING IS OBTAINED WITHOUT THE NEED FOR ADDITIONAL AIR. A BELT 5 CAN BE ADJUSTED BY A DEVICE 6, 7 WITH A PINION AND RACK, IN THE CAVITY 1 AGAINST THE LIPS 2 CONSTITUTING THE BASE FOR SUPPORTING THE CAVITY 1 ON THE WHEEL RIM.

Description

The present invention relates to a new

  type of tire for wheels in general, pre-

  feeling a special arrangement and made of rubber

  cauldron in almost full form, without inner tube or accessories therefor, this tire does not need additional air for its inflation and retaining the flexibility and damping characteristics necessary for the

rolling function.

  It is a new type of tire

  without inner tube, having components

  particular characteristics which will be

  detailed below and have been developed to

  achieve a goal that has not been achieved so far

in the technique.

  It is obvious that there are pneumati-

  without tubes and unless they are

  full, they require accessories for their infla-

  and for the maintenance of air for their use-

  sation, and not to lose their essential characteristics. The tire of the invention, thanks to the fact that it does not need additional air and that it is self-sufficient by virtue of its shape, avoids the serious problems of punctures, bursting and

  deflation, thus always retaining its structural form

  to allow permanent rolling of the vehicle

  hicle without the inconvenience caused by a pneuma-

tick become abnormal.

  The object of the invention is to allow

  solve common problems on common vehicles

  countered so far, even in the case of tires-

the most sophisticated materials.

  To this end, the subject of the invention is a tire for a vehicle wheel, characterized in that it comprises an interior cavity in the shape of a vault and having an area approximately equal to fifty percent of the total area of the tire.

  interior and exterior, which provides an effect of-

  death and flexibility when riding, without

extra air care.

  Therefore, thanks to this arrangement, the

  new tire design has the features

following features:

  a) an interior cavity having a surface of

  about fifty percent of the total dimension of the

pneumatic; -

  b) this tire has in its base part two upper wavy lips, ending in

  rectilinear walls which form a mutual joint when

  that they bear on the surface of the rim, these lips being further arranged so as to support an adjustment belt; c) an adjustment belt making it possible to adjust the tire on the rim and shaped so as to

  marry the undulation of the base of its interior cavity

  re, this keel fixes and prevents its displacement out of

  the rim during rough or violent driving, the eff-

  strong adjustment that can be adjusted using a

  mechanical positive with rack.

  Other features and benefits of

  the invention will emerge from the description which follows

  vre of an example of a bicycle tire given-without limitation, with reference to the accompanying drawings in which:

  - Figure 1 is a section of the tire in ap-

  then on the rim, - Figure 2 is a perspective view of the

  tire adjustment belt, with its rack

  1st, - Figure 3 is a detail view of the toothed wheel driving the rack in the tire and the rack area, - Figure 4 is a perspective view on a larger scale of the metal capsule used

  to assemble the belt sprocket and the

Maillères,

  - Figure 5 is a section of the belt in ap-

  then on the wavy parts of the lips lying at

the base of the cavity.

  We see in Fig. 1 the internal cavity 1 having a profiled base and on which the adjustment belt will be fixed and supported, 2

  being a wavy lip of the support base, 3 the over-

  bearing face itself of the tire on the rim,

  4 the joint section between the lips, in their part

  straight tie, when the tire is pressed on the

  rim, and 5 the belt section when it adjusts

  te the wavy part of the tire lips (cons-

tituant the base of the cavity).

  Fig. 2 shows the planned racks 6

  at the ends of the belt and to be action-

  born by means of a toothed wheel 7 which drives these cre-

  mesh and protrudes from the rim, through

  to the inlet port normally used to pass the conventional valve. We can still see the body 8 of the belt and the metal capsule 9 used to

  assemble this belt. The belt 5 can be reset

  made of plastic, in massive form, it can also be constituted by a metal band, a special plastic cable or under any

other suitable form.

  We still see in Fig. 3 the tire

  10, the edge 11 of the rim, the locking device 12

  wearing of the toothed wheel, the body 13 of this toothed wheel

  tee, and the hexagonal head 14 of this wheel body den-

  tee, used to adjust, tighten or loosen, the rack. Tightening or loosening can

  be obtained using a small plastic lever

  than, metal or other material.

  We find in Fig. 5 the rigid body 8 of the belt, with parts 15 of force concentration of this belt on the base of the tire, in order to fix it on the edge of the rim, with in

  16 the section of the belt which works at the dilata-

  tion on the tire support lips on the tire

you.

Claims (4)

  1. Tire for vehicle wheel, charac-   terized in that it has an interior cavity (1)   in the shape of a vault and presenting an approximate surface   equal to fifty percent of the total surface of the interior and exterior tire, which provides a cushioning and flexibility effect   when driving, without the need for additional air.   2. Tire for vehicle wheel, charac-   terized in that it comprises, on the base (3) of the tire-   matic, lips (2) of special shape forming a mutual seal when placed on the rim, with,   in their upper part (lower base of the ca-   vity (1)), corrugations on which an adjustment belt (5) is put in place to exert its force.   3. Belt intended to be associated with the-   inner part of a tire, which can be removed   placed through the interior vault cavity (1) for an adjustment on the lips (2) constituting the support base of said cavity (1) on the rim, this belt (5) being for example of a material solid plastic, metal tape, cable special plastic material.   4. Gear adjustment device for a belt (5) disposed at the inlet   the valve of a pneumatic wheel and put mechani-   only energized by rotation using a pe-   tit lever: which can be achieved for example by plastic or metal.
