Description

Footwear for recreational or sports use.

Technical field

The present invention concerns a shoe for recreational or sports use equipped with an elastic sole and oversized that provides a great bounce capacity over relatively hard floors, allows you to easily slide over smooth surfaces, sand, water, snow, ice and the like, provides an ascending force when immersed in water, and at the same time allows walking and running with almost total normal.

Background of the invention

The patent US-A-5261984 describes a shoe for fun that has a top sole, a bottom sole and a plurality of coil springs arranged between the sole upper and lower sole to give footwear an effect Rebound. The space between the upper sole and the lower sole where the coil springs are located is closed by a for elastic wrap. The upper sole has a means of retention to retain the foot of a user attached to the footwear. The bottom sole has a ground contact surface with anti-slip devices in the front and rear ends of it. An inconvenience of this footwear is that the bottom sole has approximately the same dimensions than the upper sole in contrast to a relatively great distance between the bottom sole and the top sole, and this It makes footwear difficult to handle. Also, with this shoe the bounce effect is incompatible with a slip effect due to the mentioned devices anti-slip

The patent GB-A-2384610 unveils a shoe for exercise and fun that has a superior sole, a sole lower and a swollen chamber arranged between the upper sole and the bottom sole to provide a rebound effect. The sole upper carries a retention means to retain the foot of a user attached to footwear. The bottom sole, the top sole and the swollen chamber are approximately equal views in plan and they generally have the shape and dimensions of the user's foot. A disadvantage of this shoe is that the contact surface with the ground is relatively small in relation to height relatively large swollen chamber, and this makes the bouncing effect is difficult to control and the footwear is not appropriate to provide a sliding effect on smooth surfaces, sand, water, snow, ice, among others.

The utility model CN-A-2925166Y describes a shoe sports suitable for water and land comprising a shoe and a inflatable and pressure resistant chamber fixed to the part bottom of the shoe. The inflatable chamber has a hole for the swollen. When walking fast on land the inflatable chamber provides a rebound effect and in the water creates a force ascensional A drawback of this shoe is that the surface of contact with the ground is relatively small in relation to the relatively large height of the swollen chamber, and this causes the rebound effect is difficult to control and the footwear is unsuitable to provide a sliding effect on smooth surfaces, water, snow, ice, among others. Also, given the relatively small volume of the inflatable chamber in relation to the shoe, the ascending force produced when it is submerged in The water is relatively small.

Exhibition of the invention

The present invention contributes to mitigate the previous and other inconveniences providing a shoe for use playful or sporty, comprising a sole configured to receive a foot of a user, whether bare or footwear, some elements of fastening to fasten said foot to said sole, and a member of elastic lift for contact with the ground attached to the sole. The mentioned elastic support member is capable of deform elastically with a high rebound capacity, and is oversized at least 150% in both length and width with respect to said sole, that is, the support member elastic is at least 50% longer and 50% wider than the sole. In general, the sole is approximately centered with respect to an upper surface of the elastic bearing member. Preferably, the elastic lift member has a height (from a ground contact surface to a upper surface adjacent to the sole) smaller than its width The elastic support member has a contact surface with curved, convex and smooth enough floor to provide slip on smooth surfaces, sand, water, Snow, ice, and the like.

Due to the relatively large dimensions of the elastic support member in relation to the sole, the footwear of the present invention exhibits a high capacity of bounce on relatively hard soils, such as pavements, land, sand and the like, provides a high capacity for sliding on smooth surfaces such as polished pavements, wet or waxed, sand, water, snow, ice, and the like, and provides a high ascending force when the footwear is submerged in water

In addition, due to the fact that the member of elastic lift is relatively flexible, the parts of the same that protrude in front and behind the sole is easily deform or bend, allowing the user to walk or run with almost total normality, since when making the step the footwear adapts to the anatomical need of the passage, contrary to what happens with skis, plates, or the like, that being rigid, they do not allow to walk with natural step, but they force the user to drag the feet, in the case of skis or similar, or to walk unnaturally, in the case of snow shovels, irons or similar

In one embodiment, the lift member Elastic comprises a closed chamber filled with a gas. Preferably, said chamber is defined by walls made of a polymeric material, such as an elastomer, and is provided of one or more inflation valves. The camera can have one or more interior partitions. Preferably, the sole and the camera are formed as a single molded piece, and more preferably this molded part also includes the aforementioned elements of subjection.

In another embodiment, the camera has a shape elongated annular tubular, with a front section, a section rear and two adjacent longitudinal sections, and the sole is formed separately and attached to the chamber, for example by welding or adhesive In this case, the camera can be formed as a molded part of a polymeric material, such as an elastomer, or as a tubular ring of a crushed elastomeric material laterally later to form the mentioned sections adjacent longitudinal. The sole and the fasteners they can be formed as another molded part of a material plastic.

In yet another embodiment, the member of elastic lift is solid and made of a material Foamed polymer closed cell. Also in this case the sole and the fasteners may be formed separately as a molded part of a plastic material or any other fashion and material. The sole is attached after the member of elastic lift, for example by welding or adhesive.

In general, sole has the form of a raised platform with respect to an upper surface of the elastic support member, although optionally the sole it can be at the same level as the upper surface of the member of elastic lift or integrated in a dimension plate greater than the sole and raised above the surface upper of the elastic support member. The elements of fastening can comprise laces, straps, adjustable straps, etc. In one embodiment, the fasteners comprise a elastic heel element and an elastic instep element similar to the fasteners used on skis aquatic

Whatever the basic embodiment of the elastic support member, the ground contact surface may be completely smooth or have one or more longitudinal ribs arranged along at least part of it. Alternatively, the floor contact surface of the elastic support member may have one or more longitudinal grooves disposed along at least part thereof. It is also provided that the floor contact surface of the elastic support member may have a combination of ribs and longitudinal grooves. These ribs and / or longitudinal grooves will be sized to help guide a slide of the elastic support member in a forward / backward direction and to contribute to slowing a slide of the elastic support member in a direction.
