FR2471755A2 - SPORTS SHOE EQUIPPED WITH A DYNAMIC TONGUE - Google Patents

Abstract

A sport shoe (1, 50, 70) having a tongue assembly (15, 30, 55, 76) comprising an upper section (16, 31, 56, 85) and a lower section (17, 32, 57, 86). The upper and lower sections (16, 17, 31, 32, 55, 56, 85, 86) are movably coupled so that, as the upper section (16, 31, 55, 86) is moved toward the toe of the sport shoe, the lower portion of the upper section (16, 31, 56, 85) and the lower section (17, 32, 57, 86) press a foot rearwardly and downwardly toward a heel cup (5, 79) of the sport shoe (1, 50, 70).

Description

247 1755

  This addition relates to footwear systems for sports shoes in general

  and in particular a new shoe fitting system

ski sures or the like.

  A classic shoe currently in use

  for downhill skiing has a lower shank or upper

  very rigid and a top of the rod or bracelet as well as a relatively soft lining. The upper and the strap are intended to provide mechanical protection and support

at the foot, ankle and lower part of the leg

  be, while constituting a stable device for fixing the boot in a removable manner to a ski. The vamp and bracelet are frequently hinged together near the ankle. Shoes made with a swivel strap generally provide protection against excessive ankle friction, both laterally and backward, while allowing limited friction of the leg forward relative to the foot. It happens more

  rarely that shoes are made without bra-

pivoting eyelet and that their forward bending is limited or authorized by the presence of a separate front part of the bracelet. In addition to providing mechanical support, the relatively rigid upper and strap must limit, with the relatively soft lining, movement of the foot upward, forward, backward

  and laterally, This limitation is advantageous for mini-

bet on the lack of comfort and fatigue resulting from

repeated pressure on certain areas of the foot and a

vement of the latter in the shoe. It is also

  Also necessary to master the skis during execution

  various maneuvers during a descent and in various

its terrain and snow conditions. In addition, it is essential to minimize the movement of the foot in order to maximize the transmission of energy between the foot and the

  safety fastening in the event of a dangerous fall.

In practice, the degree of limitation necessary

  re from one movement to another varies according to the changes

conditions for skiing and maneuvers at

  execute. Theoretically, the shoe must ensure a shoe-

  comfortable, well-adjusted but not too tight so as not to impede blood circulation and warming of the foot during the straight line skiing phase, while

  ensuring at least one momentarily tighter fit

during the phase of negotiating a turn or others

  maneuvers requiring the exercise of a certain force.

With the exception of certain forms of realization

  tion of the prior art, ski boots of conventional design do not adequately compensate for

dynamic conditions prevailing during a descent.

  With conventional shoes, when negotiating a turn while skiing on packed snow, forward bending at the ankle is usually accompanied by a tendency of the rear part of the foot to lift and the front part of the foot to perform a lateral movement since the control of the ski and the execution of a turn are usually carried out by applying a downward force

and laterally at the front edges of the skis. In the snow for

dreuse, the front edges are held in the high position to slide on the snow surface, the front part of the foot

tending to perform an upward and lateral movement.

When it comes to maneuvering in snow of different consistencies or on bumpy terrain, the skier frequently and quickly changes position between bending forward and bending backward in the boots. As a result of this movement, mastery of skis is very reduced. During most falls which cause injuries, excessive movement of the foot in a shoe also reduces the transmission of energy between

the foot and the fixing.

Because of the high cost of manufacturing the molds,

  rods it has been common practice to provide a limited number of rod dimensions. Manufacturers have

  then resorted to hooks allowing many re-

complex glages and linings of various configurations

  tions and constructions to ensure tight, comfortable and warm footwear, to compensate for the very numerous

foot dimensions and shapes and get the required outfit

  sit up. However, these footwear systems are generally not satisfactory. The use of

hooks for many complex adjustments work

  usually results in an uncomfortable fit. Closing the hooks to ensure a tight fit is

  also usually translated by areas of pressure

  comfortable due to the resulting form of the em-

  relatively rigid comb. In addition, the conventional systems

  that using hooks does not properly prevent the foot from making lateral movements both at the rear

than at the front.

The use of linings of various confi-

gurations and constructions also usually results in a more comfortable fit. Because of the difficulty of making linings of configurations which match the very many different dimensions and shapes of the feet, for example a flat or wide forefoot, a wide plant,

flattened heel, square toe, bone prominences

  thresholds, lugs, a long longitudinal arch

  or a foot of a different dimension from the other, the dou-

  wounds are generally made so as to cover only a limited range of dimensions and shapes0 Manufacturers then rely on various constructions of linings for

obtain a tight and comfortable fit. Among the cons-

  tructions used, we can cite soft foam rubber

  sheet and sheet, urethane foam, wax, cork,

  plastic pellets and various other materials

  more fluid. The large number of materials used is

an indication of unsatisfactory results.

Despite the above footwear systems, conventional shoes do not allow a suitable fit for comfort and hold and it is necessary to have a relatively large stock of rods and linings of different configurations and constructions

to satisfy customers. In addition, a fitting footwear

doing when trying on in the store is still often unsatisfactory for downhill skiing, as the foot is not necessarily fitted to meet the conditions

a ski descent.

When examining the various possibilities, there seem to be three parts of a classic shoe that can provide a dynamic boot for a shoe

sports in general and a ski boot in particular.

  These parts are as follows: 1. A mobile bracelet; 2. A mobile platform supporting the 0-plantar arch; and 3. A movable tab as described in the

present brief.

In view of the above, the main subject of the present invention is a sports shoe and a footwear system, in particular sports shoes.

  ski, which reduces the number of stem sizes and con-

  figurations and constructions of linings necessary to ensure a narrow, comfortable and warm fitting, as well as the necessary holding of the foot for a large range of

  shoe sizes and shapes, while adjusting dynamic-

  the footwear of the shoe has a foot during all

the maneuvers carried out during skiing.

  The present invention also relates to a footwear system which requires only one adjustment for fitting the foot; which dynamically serves the boot of the boot when the skier leans forward and loosens it when he leans back; the main dynamic adjustment elements of the footwear of the shoe comprising a movable tongue consisting of an upper part and a lower part, a means intended to connect the lower part to the upper part in a mobile manner and a means intended to couple in a movable manner the upper part to the shoe; and that

includes a movable tongue as mentioned above,

both a means for coupling it in an adjustable manner to the shoe in order to adjust the fitting of the latter to

  feet of different dimensions.

In service, when tilting towards the

the upper part of the shoe. When the su-

  pivot swivels forward, the lower region of the

upper part and lower part pivot backwards

  back and down so as to press the foot back and down towards the heel. In a form of

realization, the upper and lower parts are re-

  movably linked along their lateral edges and, alternatively, the upper and lower parts are

articulated in their middle region.

The invention will be described in more detail below.

  We will now examine FIGS. 1 to 6 which, in accordance with the invention, represent a ski boot generally designated by 1. The boot 1 comprises a bottom of upper or upper 2 and a top of upper or bracelet 3. The upper 2 has a sole 4, a shoe

stage 5 and a front part 6 intended to cover and pro-

cover the front part and the fingers of one foot.

  Bracelet 3 is hinged to upper 2 by

a rivet or the like 7.

A lining generally designated by

  8, which extends inside the upper 2 and the bra-

celet 3, provides warming and comfort for the foot.

  The lining 8 consists of a front part 9 and a part

rear tie 10. The front 9 and rear 10 parts are se-

  trimmed along a lateral line generally designated by it to facilitate the introduction of the foot into the shoe. To guarantee warmth and a comfortable and tight fit, parts 9 and 10 of the lining

slightly overlap as indicated by a dotted line 12.

  Immediately behind the part of the shoe

  sure covering the kick is a tongue

bile generally designated by 15 and consisting of

an upper part 16 and a lower part 17.

  This lower part 17 is movably connected to

the upper part 16 at a first place 18 and at a

  cond place 19 located between said parts 16 and 17 and

  near their right and left side edges. The part

lower 17 has a configuration such that it covers a large part of the kick and forefoot so

minimize movement of the foot forward and to the sides.

  The upper and lower parts 16 and 17

  are coupled in places 18 and 19 by an elastic material

tick used for the manufacture of said parts. In

  variant, they can be articulated together by a ri-

vet by providing other appropriate means to ensure

the elastic joint of the two parts.

In addition to their elastic articulation, the parts

upper and lower 16 and 17 are separated by an es-

empty space generally designated by 19A, along a line connecting the first and second locations 18, 19 passing over the kick. The upper parts

  and lower 16 and 17 are separated by a predefined distance

  ended along a line running through the middle of the bottom edge of the top and the middle also

  upper edge of the lower part, predeter distance-

mined which corresponds to the predetermined maximum movement with respect to the lower part 17.9 bringing the part closer

  upper 16 of the end of the shoe.

  In order to movably connect the tongue & the shoe 1, the upper part 16 is coupled

to the upper 2 by two studs 20 and 21 in the form of a rivet.

In order to adjust the position of the tongue 15 relative to the socket 5, the tenons 20 and 21 each have an internal head 21e and an external head 21B to secure the

  upper part 16 in a boutolulnnière designated in a fa-

  general lesson by 22o The buttonhole 22 has an oblong lower slot 23 and several shorter slots 24, 25 and 26 oriented generally upwards and vertically from the latter. Each of the slots 24, 25 and 26

  have two parts 27 and 28 of their edges which sail

  binds inward. As shown more clearly in Figure 4A, the projections 27 and 28 are intended

to fix the pins 20 and 21 in the slots 24.9 25 and 26.

  The heads 21B of the ends of the pins 20 and 21 prevent them from being pulled out of the slots 24 to 26 towards

inside the shoe.

  The upper and lower parts 16 and 17 of the tongue 15 are made with padding 16A in a relatively soft material similar to foam.

  the interior and a relatively rigid envelope 168 ex-

  inner, envelope to which the internal padding 16A

is fixed.

As seen in Figure 6, during

tilting forward, the upper part 16

  vote around the axis of tenons 20 and 21 towards the

  end of shoe 1. As shown in dotted lines, when

that the upper part 16 pivots towards the end of the shoe

247 1-755

on 1, the lower region of said upper part 16 and the lower part 17 pivot backwards and downwards so as to press the foot backwards and downwards

  towards the socket 5 at the lower rear end

  re of the vamp 2. When tilting backwards, the upper part 16 and the lower part 17 pivot

in the opposite direction to reduce the pressure imposed on the foot.

  The space 19A separating the upper and lower parts

16 and 17 form a play which allows said parts to pivot

  ter when tilting forward.

In order to adjust the tongue to feet of different dimensions, the pins 20 and 21 are moved from one of the slots 24 25 and 26 into another by pushing the pins beyond the protrusions 27 and 28 in the slot 23 When the desired fit is found, the pins are pushed back beyond the protrusions 27 and 28 in

the desired slot.

FIGS. 7 to 11 show in another embodiment of the present invention, a variant of the movable tongue which is generally designated by 30. For the sake of clarity, the elements of FIGS. 7 to 11 which are identical to those shown in Figures 1 to

6 have the same references.

  The tongue 30 consists of a top part

  31 and a lower part 32. The upper parts 6-

lower and lower 31 and 32 are elastically coupled in a movable manner in the middle of the upper edge of the lower part 32 and of the lower edge of the upper part

31. From the middle to their lateral edges, -the said upper parts-

  lower and lower are split so as to form two

paces 33 and 34 between them. Along their midline,

upper and lower parts 31 and 32 are coupled

Plastically bent by an elastic element 35. The latter is subject to the lower part 32 by one or more lower fixing elements such as a rivet 36. Also, the upper end of the element 35 is subject to the upper part 31 by a removable fixing element such as a spring screw 37. As can be seen in FIG. 10 above the spring screw 37 there is one or more holes 38. These are intended to allow the position to be moved of screw 37 to modify the force necessary to change the configuration of the element

elastic 35.

Like the tongue 5, the one designated by 30 has a padding 16A comprising an internal material similar to foam and a rigid outer envelope 16B to which the padding is fixed. To connect the upper part 31 to the upper 2, it has two pins 20 and 21 intended to fit in a buttonhole 22 formed for this purpose in the upper 2, as described above in

  referring to the embodiment of Figures 1 to 4.

  In service, except that the upper and lower parts 31 and 32 of the embodiment of Figures 7 to 11l move around an axis passing through the middle of the parts of the tongue rather than a passing axis by their lateral edges, a movement of the upper part 31 causes the corresponding movement back and down of the lower part 32 to press the foot down and back towards the casing 5 as is described it above for the form

of Figures 1 to 4.

  It goes without saying that many modifications can be made to the shoe described and represented.

without departing from the scope of the invention.
