Abstract

1. Mounting- and closure device for shoe, characterized in that between the upper (1) and the sole of the shoe, a strap (3) is fixed at the level of the plantar hollow which constitutes in the foot, in extension, the place where the strains are transmitted, said strap (3) entirely gripping the upper (1) of the shoe, and one of the ends of the strap (3) having a buckle (4) in which is engaged the other end which is folded back and fixed on the strap (3) by connecting means, said buckel being slightly bent in order to allow by shifting of the folding part in one direction or the other, an anatomical adaptation to all insteps.

  Mounting and closing device for shoes.

  The present invention relates to a device for mounting and closing shoe and more particularly for

sports shoe.

  To highlight the various functions performed by the shoe, it was necessary to carry out the study

  anatomical problems, namely the study of the best adapta-

  foot to the shoe and its work surface.

  In particular, in the field of sports shoes, it is very important that the efforts developed by the athlete are transmitted with the minimum of deformation and, in the best conditions of physiological comfort for the foot. In addition,

  very often, the lightness of the shoe is an important element.

  The compromise therefore lies around the shoes suf-

  designed to prevent deformations from affecting mechanical transmissions and sufficiently flexible and light

  meet the requirements of the competition.

  The present invention aims to ensure total solidarity between the foot and the shoe while ensuring comfort

  and maximum safety at the least weight.

  According to the present invention, use is made of a mounting and closure device for shoes, characterized in that between the upper and the sole of the boot is fastened a strap at the level of the plantar hollow which constitutes in the foot in extension the place o are transmitted forces, said strap enclosing

  the upper of the boot and having a closure member

  ture ensuring the connection of the two ends of the strap.

  The return of the strap is done through a slightly curved loop, allowing by a shift of the

  part folding in one direction or the other an adaptation analog-

tomicles to all the instep.

  This strap also ensures the support of the plantar vape, thus avoiding the deformations of the foot structure (flat feet) noted by chiropodists, and reducing fatigue

following the effort.

  The front and back of the shoe can

  be assembled with all methods of assembly, with or without

  assembly or reinforcements (fins, ends)

hard, buttresses, hungers).

  The use of the radial mounting of the closing strap

  ture also eliminates conventional closures by giving the

  rage of the foot the maximum adjustment possibilities, the maintenance being

  guaranteed by the total dimensional stability of the strap.

  The weight reduction provided by the invention is also

  important because of the extreme simplification of the

  floor and closing and the removal of crushproof reinforcements

  usually used to overcome longitudinal deformations.

  The device according to the invention provides additional security that results from the removal of lacing and loops

  may occasion certain incidents, such as untimely opening

  the fall due to the shoelaces lying around, the important deformations

  aunts causing the heaving, the dysfunction of the foot in

  stress that can cause cramps or other discomfort.

  In the effort of the foot in extension (in most sports disciplines) and more particularly during the position

  (cycling) the deformation of the classic shoe is

  kills essentially longitudinally, the point of application of the force being at the heel while the point of contact with the

  ground, so resistance to effort, lies under the forefoot.

  The device according to the invention overcomes this inconvenience.

  deny to the extent that the tightening of the foot in the plantar hollow allows the application of the force on the entire radial strap,

  which increases the distribution area (hence less distortion

  same effort) and brings the pulling point closer to the point

of resistance.

  In addition, the coefficient of deformation of the strap itself is small, negligible at the level of the forces applied by

the athletes during the effort.

  In certain sports disciplines where the foot reaches high speeds, particularly cycling, the aerodynamics of the shoe is essential. The closure of the strap

  crocheted velvet makes it possible

  the hooks on the part with loops,

  excellent air penetration significantly higher than

conventional positive closure.

  Other features and advantages of the invention

  will be better understood by reading the following description

  of an embodiment and with reference to the accompanying drawings, in which: FIG. 1 is a top view of a shoe;

  according to the invention, mounted on a shape and with the strap in position

  open; Figure 2 is a similar view from above of the shoe with the strap in the closed position; and Figure 3 is a bottom view of the shoe

  according to the invention with the sole disassembled and the strap posi-

closure.

  In Figures 1, 2 and 3 there is shown a shoe and more particularly a sports shoe on which is fixed between the rod 1 and the sole 2, a strap 3 completely enclosing the rod 1 of the shoe. The strap 3 is fixed on the rod at the level

  of the plantar hollow which constitutes in the foot in extension the

  right o are transmitted efforts.

  One end of the strap 3 comprises a loop 4 in which is engaged the other end 3a of the strap which is folded over the upper part of the strap. To ensure the maintenance of the end 3a of the strap on the upper part of the latter, using a known closure means, but more particularly a pile velvet which has on the faces facing the strap, series of hooks which are engaged in

series of loops.

  The loop 4, slightly curved, allows by shift of

  the folding part in one direction or the other an adaptation

tomicles to all the instep.

  Of course, various modifications can be made.

  by the person skilled in the art to the device or process which has just been described by way of non-limiting example without departing from the

framework of the invention.
