Description

This addition relates to a device new assembly of a footwear item cut from a single piece piece. According to the invention described in Patent No. 89,16681. The device according to the addition includes according to A first characteristic. A delimited assembly strip. by two cuts made in one of the upper halves, comes to enter an assembly window made on the other half upper, a tongue of assembly cut in one piece one of the upper halves is used to key the device. The device according to the addition includes according to a second feature is an assembly clip which can to be made of different materials and which can reinforce or replace the assembly tab according to the first characteristic that. The device according to the addition includes according to a third characteristic, a delimited assembly strip by two cuts made in one of the upper halves, comes to enter through a window / tongue cut into the other half upper. According to a particular method of embodiment, the Fenè The tongue, larger than the assembly strip, is cut supported on only three of its sides, an internal tongue of The window ensures the locking of the device replacing the Assembly tongue according to the first characteristic. According to specific embodiments The orientation of the cuts, their dimensions, their arrangement for use: the joining strip, the joining tongue, The assembly window and / or the assembly clip can go rier in the upper halves where they are positioned and / or It is then stapled. The reference axes of the upper halves (2 and 3) are lines parallel to the median axis of the sole zone (1). These reference axes can move laterally to the median axis of the sole zone (1) throughout all zones (19 and 20). The angles of the various cuts will be determined with respect to these reference axes. According to the addition method, the footwear item may include several assembly windows and several Assembly strips. Depending on the addition method, the shapes of the cutouts in the assembly window(s), the assembly strip(s), and the assembly tongue are variable. straight, broken, or rounded shapes in the form of rectangles, squares, trapezoids, concave, convex, triangles, etc. The cutting angle of the assembly tongue can to be different from the cutting angles of the Benètres, or of the assembly strip(s). The attached drawings illustrate the addition: Figure 1 represents the device according to the first character characteristic of addition. Figure 2 represents the device according to the second character characteristic of addition. Figure 3 represents the device according to the third character characteristic of addition. With reference to these drawings, the device according to characteristics 1, 2, and 3 comprises a sole area (l) and two areas (2 and 3) representing the two upper halves. An assembly window (21) is made in one of the upper halves (2 or 3). Assembly strip (22) is made in the other half of the upper An assembly tab (23) is cut securely to one of the upper halves (2 or 3), indifferently on the window (21) side or Band(22). The Band(22) side seems more favorable. The reference axes (25 and 26) of the upper halves (2 and 3) are lines parallel to the median axis of the Sole zone (1). The reference axes (25 and 26) intersect perpendicularly the sections of the Window (21) and those of the Band (22). The axes (25 and 26) move laterally on either side of the axis of the Sole zone (l) throughout the entirety of the zones (19 and 20) From its axes (25 and 26), the angles and dimensions of the cuts of the Window (21), the Strip (22), and the tongue (23) will be determined. The cut angle (28) of the Window (21) and the cut angle (27) of the Strip (22) have values ​​between 0 and 180 degrees. Their most common values ​​are around 20 degrees. The cut angles (29 and 30) of the Tongue (23) have values ​​between 0 and 270 degrees, with the most common value being around 20 degrees. Angles (29 and 30) have values ​​such that, in the keyed position, the Tongue Usually, angle (23) must be inserted / perpendicular to the cuts of the strip (22). However, other angles are not excluded. The dimensions of the window (21) and the strip (22) will fit: for their minimum dimensions within a square of 0.5 centimeters per side, for their maximum dimensions within a square of 10 centimeters per side. All intermediate possibilities are common. The dimensions of the tab (23) must allow it to fit well within the strip (22). Its width will be between 0.5 and 10 centimeters, the most common width being around 4.5 centimeters. Its length will be between 2.5 and 15 centimeters, the most common length being around 10 centimeters. According to the addition method, the footwear item may include several Windows (21) and several Bands (22). The cutout shapes of the Window (21) of the Band (22) and the tongue (23) are variable. The most commonly used shapes are: triangular, rectangular, square, trapezoidal, concave, convex. They are made up of straight, broken, curved lines, etc. In the embodiment shown in Figure 2, a clip (24), which can be made of various materials, is added to or replaces the assembly tab (23). Its external shapes are variable. The dimensions of the clip's attachment tab (24) will be between 0.5 and 10 cm for its width, and between 1 and 12 cm for its length. The widest The standard length will be approximately 4.5 cm; the most commonly used length is located around 10cm. In the embodiment shown in Figure 3 The Assembly Window (21) is replaced by a Window / Tongue te(31)one of whose sides remains attached to the upper half(2 or 3) in which it is practiced, whatever form it may take of cutting retained. The Tab (23) according to the first and second characteristics is removed according to the third characteristic that. The keying according to the device of the third characteristic The seal is ensured by the internal tab of the window / tongue. te(31), which is introduced into the Band(22), either from bottom to up, either from top to bottom, or from right to left, or from left to right. The Renètre / Languette(31) and the Bande(22) according to the third characteristic are made in their respective half vamp(2et3) according to the first and second characteristics. Device according to the first, second and third characteristics, the dimensions and shapes of the window (21) of the band' (2?)cTe lat languette (73) of the fen:ètr.e / languet.te (31) can be independent of each other The device according to the addition concerns the realization of a footwear article cut from a single piece.
