Abstract

Footwear with helium camera. Composed of a shoe whose sole is composed of two horizontal layers, an interior joined to the instep and an outer one that supports the heel of the footwear. Both layers are polished by their interior and treated with antiporosity products. Between the two layers there is a camera. In the heel or other convenient place, depending on the type of footwear, there is a hole in which is embedded hermetically an inflation valve with exit to the interior of the chamber, through which the helium or other gas is introduced. Characteristics. The said hole is provided on the outside with a plug that closes the hole leaving inside the inflation valve. (Machine-translation by Google Translate, not legally binding)

Description

Footwear with helium chamber.

The present invention relates to the incorporation into the footwear of a helium chamber located in the plant that gives this greater flexibility, comfort and weight reduction

Based on the fact that helium is a less heavy gas that the air, which remains stable and harmless in small quantities, the present invention proposes to add this gas to the footwear, in airtight chamber, in order to lighten the weight of these.

Its field of application is framed in the footwear manufacturing industry and uniquely in the auxiliary shoe industry with air chamber.

They know each other in this industry sector Some models that do not contribute to the state of the art novel features proposed by the present invention. Thus, the Document ES 2 039 319 presents a sole for footwear that incorporates a wedge of flexible material, also document 2 145 893 proposes a type of sole for footwear that draws air from inside and he expels it abroad.

These documented models, presented to the proposed invention the following drawbacks:

The flexible wedge, although it may give a feeling of comfort, does not reduce weight to footwear, because it does not exist in manufacture no element lighter than air. The sole that it draws air from the inside and expels it to the outside, although it is appropriate to keep footwear odor free, it does not present any relief for diminished people, elderly and athletes.

Normal shoes have the disadvantage versus the one proposed by the present invention for less comfort, Little lightness and more fatigue when walking.

Given these inconveniences described, the present The invention brings innovative solutions to the state of the art, simple and easy to execute that result in the following advantages:

It has great utility in sports, because at Decreasing the weight of footwear increases the athlete's performance. Also the elderly or physically disabled can benefit from this footwear proposed by the present invention It helps you walk more comfortably and lightly. Increase the comfort, because the helium chamber pads the foot doing more nice walking. The helium introduced into the footwear acts during the march as a retractable and expansive element that Provides more comfort while walking.

All these conjugated elements give rise to a final result in which differentiating characteristics are provided significant compared to the state of the art.

Thus, the invention is constituted from the following elements: A shoe whose sole is composed of two horizontal layers, an interior, of a material appropriate to the manufacture of footwear, attached to the instep and heel by a means of adequate union. The second layer, exterior, is made based of a material with sufficient strength to withstand friction with the floor, supports the heel of the footwear.

Both layers are polished inside and treated with antiporosity products. The two layers before mentioned, are separated from each other by a rigid band or flexible, depending on the application the shoe is intended for, glued to the entire path of the edges of the two layers, forming Among them a camera. In the heel or other convenient place, according to the type of footwear, there is a hole in which it is located hermetically embedded an inflation valve with outlet to inside the chamber, where helium or other type is introduced Gas similar characteristics. The mentioned hole is provided on the outside of a plug that closes the hole leaving inside the inflation valve.

In a different embodiment a second chamber formed by two layers on the instep and heel of the footwear.

Alternatively the helium chamber occupies only the heel area or the toe of the footwear, for some sports or orthopedic applications.

In a different way the chamber formed by the two Layers remain tight and do not incorporate inflation valve.

For a better understanding of this memory Descriptive is accompanied by a drawing that by way of example does not limiting, describes a preferred embodiment of the invention:

A preferred embodiment of the invention proposal, is constituted from the following elements: A footwear (1) whose sole (2) is composed of two horizontal layers (3 and 4), an interior (3), of a material suitable for manufacturing of footwear, attached to the instep (5) and heel (6) by means of adequate union. The second outer layer (4) is made of a material with sufficient strength to withstand friction with the floor, supports the heel (7) of the footwear (1).

Both layers (3 and 4) are polished by their Inside and treated with anti-porosity products. The two layers (3 and 4) above, they are separated from each other by a band (8) rigid, attached to the entire path of the edges of the two layers (3 and 4), forming a chamber (9) between them. On the heel (7) there is a hole (10) in which it is embedded tightly an inflation valve (11) with outlet inside the chamber (9), where helium is introduced. Said hole (10) is provided on the outside of a plug (12) that close the hole (10) leaving the inflation valve inside (eleven).

Claims (4)

1. Footwear with a helium chamber consisting of a shoe (1) characterized in that the sole (2) is composed of two horizontal layers (3 and 4), an interior (3), of a material suitable for the manufacture of footwear, subject to the instep (5) and to the heel (6) by a suitable means of attachment. The second layer (4), exterior, is made of a material with sufficient strength to support the friction with the ground, supports the heel (7) of the footwear (1). Both layers (3 and 4) are polished inside and treated with anti-porosity products. The two layers (3 and 4) mentioned above are separated from each other by a rigid or flexible band (8), depending on the application to which the footwear (1) is intended, attached to the entire path of the edges of the two layers (3 and 4), forming between them a camera (9). In the heel (7) or other convenient place, depending on the type of footwear, there is a hole (10) in which an inflation valve (11) with outlet inside the chamber (9) is hermetically embedded, where Helium or another type of gas of the same characteristics is introduced. Said orifice (10) is provided on the outside of a plug (12) that closes the orifice (10) leaving the inflation valve (11) inside. 2. Footwear with helium chamber according to claim 1, characterized in that it incorporates another chamber formed by two layers in the instep (5) and heel (6) of the footwear. 3. Footwear with helium chamber according to claim 1, characterized in that the helium chamber (9) occupies only the heel area (7) or the toe of the footwear. 4. Footwear with helium chamber according to claim 1, characterized in that the chamber (9) formed by the two layers (3 and 4) remains hermetic and does not incorporate an inflation valve.
