PREFERRED EMBODIMENTFIGS. 1-4 show different footwear devices without impact with hidden fixing system, object of the present description.
FIG. 1 shows a shoe that incorporates a single damping device arranged in the posterior portion of the sole (1) and which it has provided a conventional template (6), the referred damping device consists of:
- A rigid bottom sheet (2), whose shape and dimensions are approximately equal to the shape and dimensions of the posterior portion of the sole in which it is located,
- A rigid (3) blade attached to the bottom blade, width less than the width of the bottom blade and of length greater than the length of the referred bottom blade, and is attached by means of fixing the sole,
- A top sheet (5) rigid whose shape and dimensions are approximately equal to the shape and dimensions of the bottom blade, one or more elements shock absorbers (4) preferably comprising springs and/or dampers, arranged between the bottom blade and top blade and one or more means of union between the bottom blade set—rigid blade with the shoe sole
The design of damping device options are as follows:
- The lower blade can be embedded in the shoe sole.
- The damping device can be incorporated in the plant of mounted and therefore to be manufactured beside this one and,
- The footwear can incorporate damping devices in its anterior, posterior, or central portion, or more than one of the concerned portions or whole sole, for example inFIG. 2 is shown a cross section of a heel feminine shoe, that incorporates two damping devices, one disposed in its posterior area and another in its previous area, can be arranged in the area of the heel.
Another example of the incorporation of the damping device is shown inFIG. 2, which shows a heel shoe, preferably feminine, in which it has arranged two damping devices, one in the back portion or area of the heel and the other in the previous or top portion, in this preferential realization the bottom blade of the two devices are incorporated in the plant of mounted and this is joins to the shoes subsequently.
FIG. 3 shows a cross section of a footwear that incorporates a plant of mounted support device (8), arranged in its anterior portion and two anchoring accessories devices (12). The support device of the plant of mounted consists of:
- An interior (9) area in an approximately equal shape to the shape of the sole shoe dimensions than the dimensions of the aforementioned sole, the above mentioned inner zone is attached at least by its perimeter to the aforementioned sole, this interior zone can be the mounting insole.
- An intermediate zone (10) of elastic material, whose inner perimeter is attached to the outer perimeter of the interior zone (9) and whose outer perimeter has a shape similar to the shape of the shoe sole and smaller than the dimensions of the aforementioned sole and
- A free zone (15) shaped by the same body of footwear and whose perimeter is overlaps and is attached by gluing or similar procedure, to the outer perimeter of the intermediate zone.
With this plant of mounted support device design, by introducing the foot in the shoe and supporting it on the ground, the foot expands and therefore expands the intermediate zone, only the material of the body of the shoe looks from outside and the intermediate zone is hidden, already all the intermediate area is in contact with the shoe sole,
An option of design of the support device of the plant of mounted is that the inner zone of the same one, is the plant of mounted of the footwear or that this inner zone is attached to the superior face of the plant of mounted.
FIGS. 3 and 4 show accessories anchorage devices, the accessories can be strings, strings or strips. These accessories anchoring devices are arranged in the inner part of the body of the shoe. Each of the above-named anchorage means may consist of two or more cuts (13) made in the interior of the footwear body material, these cuts may be reinforced in its edges and a piece of booster (14) is available in the area where it has made cuts. The incorporation of the anchoring devices enables on the one hand to incorporatesupplementary fixing10 means of the footwear and on the other hand to vary the aesthetics of the footwear, for example, according to the different garments with which you want to combined, without having to have a multitude of different models of footwear and also to convert, for example a shoe in a booty or even in a boot of high cane. In addition, cuts in which attachments are set to be on the inside of the shoe it is not appreciated on the outside of the body of the shoe.
The damping device has the function of cushioning the impacts or hits against the floor, is essential in high heel shoes, and therefore avoid the damages and pains in the joints. The concerned device produces great comfort in the march or in the race.
The plant of mounted support device and therefore of the fingers, allows the shoe body adapts to the foot that wears it, without pressing it, allowing that the device ensemble of plant of mounted support—body of the footwear widens.
Finally, being the accessories anchorage devices arranged in the inside of the body of the shoe material, these are not perceived on the outside of the shoe body. And these devices allow30 incorporate to the shoes, cords, ropes or strips in different ways, so it can incorporate additional removable shape, supplementary means of subjection of the footwear at the foot and different accessories that allow modifying the exterior aspect of the footwear, for example transforming a shoe into a booty or into a boot of high cane.
