Abstract
A sole 10 formed, on an upper 11 comprises an outsole 12, insole 13, and intermediate body 14. A hermetically sealed chamber in the body 14 is divided into compartments 15a and 16a by a divider 17a having a small aperture 18a to restrict air flow between the compartments and provide damped elastic yielding properties when the wearer's heel applies force on the insole 13 above the chamber. <IMAGE>
Description
SPECIFICATION
A Footwear Multi-layer Sole
This invention relates to a footwear multi-layer sole of the kind comprising at least an insole and an outsole and a wedge-shaped intermediate body in the heel region and between the insole and the outsole, there being in said body a hermetically enclosed chamber substantially where the wearer's heel exerts most pressure when the footwear is in use, the cross-section of the chamber diminishing from the top downwards.
The invention is envisaged as applicable more particularly but not exclusively to soles for sports shoes.
The usefulness of a sports shoe is largely determined by its sole structure, especially by the flexibility of the sole and by its ability to give uniform shock-free support to the wearer's foot.
The sole structures of some known sports shoes have the drawback that since the sole must be comparatively solid in the heel region, this has resulted in fairly marked inflexibility of the sole in this part, whereby it has become poorly adaptable to various foot shapes, this in its turn entailing detrimental loading effects which manifest themselves e.g. in the form of fallen arches and of a bone spike developing on the wearer's heel.
Another detriment is painful toes, due to sliding of the foot towards the shoe tip, and sweaty feet.
For some prior proposals, reference may be made to German Patents No. 135.595 and 953.584, German Patent application texts No.

890.045 and 116.298, Danish Patent No.
57.400, and U.S. Patents No. 2,741,038 and 4,102,061. The present invention is intended to develop further the sports shoe disclosed in U.S.
Patent No. 4,102,061 putting to practical use such experiences as have been gained in practice.
It has been found that in the sports shoe sole design of U.S. Patent No. 4,102,061 the yielding properties afforded by the cavity placed centrally under the heel may be too elastic and not sufficiently damped.
According to the present invention, a sole of the kind referred to is characterised in that the chamber is divided into an upper compartment and a lower compartment by a divider which allows restricted flow of air from the upper compartment to the lower compartment to provide damped elastic yielding properties of the sole when the wearer's heel applies force on the insole above the chamber and increases the pressure in the upper compartment.
How the invention may be put in practice is described in more detail with reference by way of example to the accompanying drawings, in which:
Fig. 1 shows a shoe with a sole according to the invention, schematically, in section on the line I-I of Fig. 2, Fig. 2 shows the sole of Fig. 1, viewed from the underside,
Fig. 3A shows a detail view in central vertical section, equivalent to Fig. 1, through the shoe sole at the heel, with the sole compressed Fig. 3B shows a view in section on the line III IllofFig.3A, Fig. 4A shows, in like manner as Figs. 3A, as modification,
Fig. 4B is a view in section on the line IV--IV of Fig. 4A, Fig. 5A shows, in like manner as Figs. 3A and 4A, a further modification, and Fig. 5B is a view in section on the line V-V of Fig. 5A.
Fig. 1 shows a shoe with a sole 10 moulded on to an upper 11. The sole 10 comprises an outsole 12, an insole 13, and a wedge-shaped intermediate body 14. The components 1 2, 1 3 and 14 consist of suitable rubber or plastics materials and they are affixed to each other, e.g.
by moulding or cementing. The body 14 gives an appropriate shape to the sole 1 0. The components 12 and 13 may be substantially plate-like. The outsole 1 2 presents a reliefembossed wearing surface 1 9 and is extended into foxing strip 12a.
As shown in Figs. 1,2, 3A and 38, a hermetically enclosed chamber forms an air cavity disposed at the centre of the heel area, with an upper compartment 15a and a lower compartment 16a, shaped in the body 14, for example by boring. The compartments seal hermetically against the outsole 12 and against the elastic insole 1 3. The upper compartment 15a has the shape of an upwardly widening truncated cone, and the lower compartment 1 6a is substantially cylindrical. The shape of the upper compartment 1 5a endows the elastic inner sole 13 under the wearer's heel with suitable progressive elastic yielding characteristics, which are further improved by means of a divider 1 7a having in its centre a small-diameter flow aperture 18a.
The mode of operation of the elastic sports shoe sole of Figures 1 and 2 is described below, with reference to Figs. 3A and 3B. As shown in Fig. 3A, the elastic insole is in the position 1 3, indicated by dot-and-dash lines, when no load is acting on the shoe sole. When the shoe is pressed against the ground, the elastic insole 1 3 will yield elastically in the heel area, and to some extent also in the area of the arch, owing to the chamber.
In this connection, at first, in the compartment 15a the pressure P1 rises to surpass the pressure
P2 in the lower compartment 16a. The differential pressure AP=P1-P2 tends to become equalized somewhat, owing to the elasticity of the divider 1 7a, but mostly as a result of the damping air flow F passing through the small-diameter hole 1 8a in the divider 17a.
Such flow F continues to pass until P,=P2. In this manner, damped elastic yielding of the shoe sole in the heel area can be accomplished.
In Fig. 3A the inner sole 13 in its pushed-in extreme position is indicated with the reference numeral 13'. Similarly, the divider carries the reference 1 7a', and the compartments are indexed 1 5a' and 1 6a'. When the pressure of the wearer's heel against the insole ceases, the insole begins to rise towards the position 13, and then
P2 > P, and the flow through the aperture 1 8a is in the direction opposite to the arrow F.
In Figures 4A and 4B the upper compartment 1 sub is conical, and the lower compartment 1 6b is cylindrical. At the apex of the conical compartment 1 sub is a small-diameter aperture 1 8b, which operates as has been described. This embodiment of the invention presents no separate diaphragm, but the divider 1 7b is formed by the annular part of the body 14 entering between the compartments 1 sub and 1 6b.
As shown in Figures 5A and 5B, the upper compartment 1 sic has the shape of a truncated cone and presents in its lower part a shoulder at the transition to the cylindrical lower compartment 1 6c. Upon said shoulder rests a substantially rigid cylindrical disk forming a divider 1 7c consisting e.g. of rubber, plastics material or metal, having in its centre a smalldiameter hole 1 8c. The divider 1 7c operates like the divider 1 7a when the pressure is higher in the upper compartment. When the pressure in the lower compartment 1 6c is higher than the pressure in the upper compartment 1 sic, the disc divider 1 7c may rise and the said differential pressure is enabled to equalize very fast. In contrast, a differential pressure in the opposite direction is equalized only through the smalldiameter aperture 1 8c in a delayed fashion, whereby the desired damped elastic yielding properties of the sole can be achieved.
In the sole of the invention, the shape of the upper compartment in combination with the damped elastic yielding properties can produce a sports shoe sole which is comfortable and advantageous.
Various modifications are possible, within the scope of the following claims, for example the disk divider 1 7c may be restrained to act like a disk or flap valve, and the dividers may be wholly or partly foraminous-instead of having only one hole, and a metal plate or other stiffener may be arranged between the outsole 12 and the body
14 to prevent undue deflection of the outsole
12 or penetration of pointed articles into the chamber.
