Definitions

  • This invention relates to footwear with its sole provided with a cushioning device.
  • Sports footwear is Known m which the sole is provided with a pneumatic cushioning device interposed between the plantar and the tread.
  • This cushioning device consist s substantially of an air cushion which because of its compressibility attenuates the impact of the f oot during walking or running.
  • This known footwear offers considerable comfort to a sportsman but at the same time is limited in its use because it cannot be adapted to the individual person either to take account of physical characteristics or to take account of the particular manner in which it is used.
  • Sports footwear is also known provided with a cushioning device consisting of a gel cushion which operates not on the principle of air compressibility but on the principle of displacement of the incompressible gel mass. Diff erent cushioning effects can be obtained depending on the gel viscosity, but the effect is fixed for each type of footwear and is unable to var y as conditions vary during use.
  • a further drawback of known sports footwear provided with a cushioning device is that the cushioning effect is not only fixed but can be influenced by external environmental factors such as temperature, altitude, pressure etc. without any correction being possible.
  • An object of the invention is to provide footwear with its sole provided with a cushioning device having characteristics adaptable to the individual person.
  • a further object of invention is to provide footwear in which the cushioning effect can be adjusted in an extremely rapid and simple manner.
  • footwear with its sole provided with a cushioning device, characterised in thet said cushioning device comprises a first reservoir with deformable but inextensible walls, interposed between the plantar and tread and containing a substantially incompressible hydraulic fluid, and a second reservoir communicating with the first through a fir st passage of adjustable cross-section and a second unidirectional passage from the second reservoir to the first reservoir.
  • Figure l is a diagr ammatic side view of a first embodiment of an article of sports footwear with its sole provided with the cushioning device accor ding to the inv ention;
  • Figure 2 is a schematic view of its hydraulic adjustment circuit;
  • Figure 3 is a partial representation of a different embodiment thereof in the same view as Figure 1;
  • Figure 4 is a modification shown in the same view as Figure
  • the sports footwear according to the invention comprises, interposed between the plantar 1 and tread 2, a cushion 3 consisting of a flat reservoir with deformable but inextensible walls filled with an incompressible fluid, preferably oil.
  • a further reservoir 4 with elastically deformable walls is provided inside the article of footwear not below the plantar 1, but in a region not exposed to the impact of the foot. It can for example be provided in the side portion of the vamp or m the heel region and communicate with the first reservoir 3 through two conduits 5 and 6.
  • a flow regulator valve 7 is connected into the conduit 5 and is adjustable from the outside for example by means of a screw 8 provided with a pointer mobile along a graduated scale 10.
  • a non-return valve it, ie a valve which exerts practically no resistance to oil transfer from the reservoir 4 to the reservoir 3, but prevents its transfer in the opposite direction.
  • the two conduits 5 and 5 may consist in fact of a single conduit provided with a non-return valve in which a constriction adjustable from the outside is provided.
  • the operation of the footwear according to the invention is as follows: during use, each time the sportsman's foot presses on the Plantar 1 it compresses the cushion 3 which, because of the def ormability of its inextensible walls and the incompressibility of the oil contained within it, causes the oil to be forcibly transferred from the reservoir 4 and through the flow regulator valve 7, which in this stage is the only passage allowed. This transfer takes place at a greater or lesser rate depending on the adjustment of said valve 7, to correspond to a greater or lesser accentuate d cushioning effect in response to the impact of the sportsman's foot.
  • the assembly consisting of the reservoir 3 , the reservoir 4, the two conduits 5 and 6 and the valves and 11 form a sort of hydraulic damper which effectively attenuates the impact of the sportsman's foot on the plantar while at the same time allowing its effect to be adjusted to adapt it to the sportsman's requirements and the conditions under which it is used.
  • the embodiment shown in Figure 3 differs from the embodiment shown in Figure 1 in that the compensation reservoir 4 is fitted external to the vamp and is visible from the outside.
  • This embodiment which is operationall identical to the preceding, may be preferred in those case s in which it is required to give the footwear a "technical appearance.
  • Elastic means are inserted into the reservoir 4 to cooperate with the reservoir walls and thus obtain a more rapid and effective elastic return of the oil from the reservoir 4 to the reservoir 3 when the pressure on this latter ceases, and for adjusting this elasticity.
  • These elastic means can consist for example of a spring 12 housed in the reservoir 4 and arranged to elastically oppose the expansion of its wall, which is preferably of bellows shape (see Figure 4).
  • a screw device 13 is provided for adjusting the preloading of said spring 12.
  • the reservoir 4 consists in reality of a cylinder 14 containing in its interior a piston 15 which divides it into two chambers 16, 17, one of which, 16, communicates with the conduits 5 and 6 and houses the oil originating from the reservoir 3, while the other 17, which is completely closed, is filled with compressible fluid such as air.
  • the elastic means which oppose the filling of the reservoir 4 are represented by the compressed ai r contained in the chamber 17,
  • the air pressure in the chamber 17 is adjustable to allow adjustment of the elastic reaction to the entry of oil into the reservoir 4. This can be done by varying the volume of said chamber, and specifically by displacing its head i ⁇ by an adjustment screw 19, or by varying the quantity of air fed into the chamber by means o f a valve mot showni.
  • the footwear according to the invention is extremely advantageous in that not only does it attenuate the impact of the foot during walking or running as in the case of known footwear provided with a cushioning device, but in contrast to this latter it allows the cushioning effect to be adapted to the individual person in an extremely rapid and simple manner on the basis of the specific characteristics and conditions of use.

Abstract

La chaussure décrite comporte une semelle pourvue d'un dispositif amortisseur, lequel se caractérise en ce qu'il comprend un premier réservoir (3) aux parois déformables mais inextensibles, interposé entre la plante (1) du pied et la face inférieure (2) de la semelle et contenant un fluide sensiblement incompressible, ainsi qu'un second réservoir (4) communiquant avec le premier réservoir par un premier passage (5) de section transversale réglable et par un second passage unidirectionnel (6) allant du second réservoir (4) au premier réservoir (3).
