Abstract

The figure shows a highly raised heel with a comparatively thin, narrow underside, of the high heel type (22); an inelastic hard core component as a stabilising component (1) with a straight surface (1c) on the inner surface of the closable cover (9) of the one-piece soft flexible envelope (6) which surrounds the core (4) and is made of a layer of elastic material with high inherent damping coefficient as the damping component. When the heel sole is manufactured separately, the envelope has its maximum no-load thickness at the envelope cover (5a). When the heel sole is manufactured as part of the heel, the envelope has its maximum no-load thickness at the sole (5). The envelope is parallel (21) to the outer faces of the core and extends round all sides of the heel. The heel is attached to the surface (2) of the cover and the outer, higher envelope external wall -- compared to the core height -- by securing the upper surface (22) by a screw, nailing in the hard core (3), the screw being given stability by a hard plastic ring (10). The soft outer envelope is placed or applied by extrusion loosely with no attachment to all the inner envelope walls and is higher than the inelastic core (7a in the no-load state).

Description

Shoe heel, cushioned, fashionably increased for women's and men's footwear, in the form of a stiletto or a conical wedge

The invention relates to a shoe heel, fashionably increased for footwear in a high-heel or conical wedge shape, with a heel closed at the top and in the bottom, in which a hard, unyielding, inelastic solid or hollow core piece made of wood or hard plastic is arranged as a stabilizing element and an outer shell made of soft elastic material as a damping element, according to utility model G 9201.107.1, German Patent No. P 42 19 152.1, PCT / DE 92/00563, utility model G 92 09 230.6, utility model G 92 13 302.9, PCT / DE 92 / 00845 ... There are inventions and findings:

Patent No. DE 2933393 is a molded sole with a flat, wide shoe heel with a low height, which is damped from impact, and a soft-elastic core with high self-damping and a downwardly closed, one-piece, spring-elastic outer shell made of flexible plastic or rubber material as a damping element . The outer shoulder wall forms the spring element, while in the inner cavity of the shoulder there is also a damping element consisting of a foam or plastic with high inherent damping (= soft). An additional spring element forms an internally arranged helical spring which is filled with gas. Here, the outer shell also forms the spring element and has a core as a damping element which is as flexible as the outer spring element and, in the unloaded state, has the same height as the spring element and, under load, the outer shell and the core are equally compressed. This makes it possible for the outer jacket to be compressed to the core under load. For flat, sporty footwear, this invention is an optimal solution., The double impact damping, in which the body can save energy and the ankles are extremely relieved. For an increased heel of shoes of greater height, in which the heel end becomes thinner and the heel increases ¬ reduced footprint, there would be no stability with a soft-elastic core, since the impact force of the component, soft core and soft shell, can break away the thin heel laterally. The height of the soft elastic core is equal to the soft elastic outer shell. There would be no performance tour. Offenleguπgsschrift 2908023 shows a fashionable, raised heel, which is composed of different wedge parts. The cone intermediate layers are made of elastic material, which are attached to an upper and a lower contact surface and preferably have approximately the same thickness over the entire heel cross section. The invention is based on the object of specifying a shoe heel of a type in which there is sufficient suspension property, but a horizontal displacement of the lower part of the heel is kept within narrow limits. According to the invention, this object is to be achieved in that the two contact surfaces face each other. have projecting first and second sections, of which the first run obliquely in the running direction from top to bottom, the second opposite run obliquely. Since with this method the heel consists of several parts and these parts are permanently exposed to a high degree of mobility and friction due to compensation and decompression, this construction in terms of wearing properties will have to deal with problems of durability and are difficult to implement in almost all fashionably increased sales forms, since a high cost factor must also be taken into account here.

4. Patent No. DE 2312038 C 2 describes a heel in which a substantially rigid spacer is arranged on the inner tread side of the tread and a resiliently compressible cushion wedge is arranged on the outer heel side and extends over the entire length of the heel stretches and tapers in the transverse direction towards the inner heel side, characterized in that the cushioning is dimensioned such that in the unloaded state it gives the heel a greater height on the outside than on the inside, so that in the unloaded state the top of the heel is arranged at an acute angle to the tread, and that the cushioning wedge can be compressed under load by the body weight of the wearer until the top of the heel is aligned substantially parallel to the tread. The upholstery wedge can be expanded laterally by pressing it over the edge of the tread and the connecting surface. The heel is flat and wide. This design is certainly not suitable for heels of greater height above 3 cm, since the wedges would be too narrow to to produce an effect. The present invention is based on the object of further developing the already known heel forms to the extent that even with a thin heel of greater height, with a comparatively small tread area, the stability of the tread guide is ensured and a damping effect is nevertheless achieved to a high degree and To find components of materials which, owing to their composition and arrangement with respect to one another, permit the desired further development and even better technical designs of the inventive paragraph in production and configuration and can be produced extremely cost-effectively.

According to the invention, the object is achieved in that the claimed increased heel of greater height in a stiletto or conical wedge shape (22), closed at the top and bottom (7), with a core (1) and a one-piece, spring-elastic outer shell (6), consists of flexible plastic or rubber material (4) as a damping element. The essence of the shoe heel according to the invention lies in the arrangement of a suitable material component of the stabilizing element and damping element, the composition of the materials and arrangement having an effect on one another. This is achieved in that the raised heel in the form of a stiletto or conical wedge consists of two different materials, closed at the top and bottom (7), in different heights and widths, with a hard, inelastic, unyielding core piece (1) made of light, solid (12) or hollow (12a) wood or hard plastic, as a stabilizing element and a resilient, elastic outer shell (6) made of rubber-flexible material (4), which can be changed in its Shore hardness, as a damping element. The outer shell (6) is made in one piece, for example polyurethane, thermal rubber, thermoplastic rubber, other soft plastic materials, which can also be changed in the degree of shore hardness, so that the heel has a vertical part which can be elastically compressed in the direction of its longitudinal axis. which dampens the weight when treading, and is higher when unloaded than the inelastic core (7a). The soft outer shell has its greatest strength due to different shapes, corresponding to those of the hard core on the bottom (5), top (5a) and side walls (5b). The shape of the heel is variable in height, width, depth and shape. The heel spot (17) is molded in one piece with the walls of the outer shell (6) or is specially made for assembly, or as a repair spare part at normal height (18) and for leg length adjustment, at special height (18 a). It consists of the same material of the outer shell with one or more pins made of hard plastic, which are inserted into the pilot bores of the core lower surface during repairs. The inelastic core (1) and the soft outer shell (6) correspond exactly to each other on the inner walls. The outer wall determines the prepared mold for the spraying process. By changing the shape of the upper surface and upper outer edge of the core (16 rounded gradation, lb, 16a hook pointed or straight, lc surface total straight or ld, 16b flattened on the outside) it is achieved that after removal of the Heel can be removed from the shaft by the outer opening being correspondingly (16 rounded, 16a pointed or straight) attached to the gradation of the core (la, lb, lc) and 2. The removable cover by a snap lock of the outer casing flanging (16b) is achieved with a corresponding laterally flattened surface of the core (Id) without having to detach the entire shoulder from the shaft. The sleeve is also clamped when mounting on the shaft. The sleeve (6) can be pushed onto the core (1) in one operation, or the core (1) is already inserted into the mold before the injection process. There is no fixed connection (6a) between the core (1) and the outer shell (6). It is attached to the upper by screwing, gluing, nailing (3), pressure pin and nails (13) or in some other way. In this case, the closure of the shoulder pointing upward towards the shaft consists of the core surface (2) and the higher side walls of the outer casing (2a) = (3a).

If the heel is made with a closed (9a) or a cover (9) which can be closed by means of locking nipples or ribs, the hard core (1) has an overall straight surface (1c), and the cover is closed on the shaft (9, 9a) and the Seitenwaπduπgen the outer shell (2a) = (3b). The connection from the core (1) to the outer shell is loose (6a) or fixed (8a) after use. The covering can be attached to the core (6a) in a separate operation, or the core (1) is made before the spraying process already inserted in the mold. It is attached to the shoe upper with screws and nails (3) or in some other way, the screw and nails (3) going through the soft outer cover (9,9a) into the hard core (1). To stabilize the screw (3), a HetaH or hard plastic ring (10) is placed around the screw in a corresponding recess in the cover. The outer cover (9, 9a) is glued or loosely attached to the core piece (l): the outer cavity with cover is loose on all inner walls, without connection to the core (6a), or with a fixed cover covering on the upper core surface, without connection on the side and bottom inner walls to the

Core (8a) manufactured.

If the heel is produced without flare (16, a b) and cover (9,9a), the soft outer cover (6) is firmly connected to the hard core (8). It is attached to the upper with screws and nails. In this case, the heel is closed with the core (2) and the slightly raised side walls (2a) = (3c) pointing towards the shaft. All outer side walls of the heel are made with (11) or without (14) conical grooves, depending on the type of use. With grooves and a soft heel cover, the degree of damping is higher than without grooves and a soft heel cover, as a result of which the compression when deflected can deform due to the deformation of the material in the grooves and gives more bounce during the decompression process. The soft outer cover is suitable for all Va - ianten in unloaded condition higher than the hard core (7a).

In the case of variants with outer casing flanging without a cover, the casing can also be firmly connected to the core on the side walls of the outer casing (8) or with a cover, the outer casing on the surface of the core (8a), depending on the form of use.

In another variant, the previously described paragraph is provided with a one-piece outer shell (6) and a hard core (1), which not only receives the pilot hole for the fastening screw towards the shaft but also pre-drilled holes (17) into the lower one Core surface, for a necessary repair. During the repair, the height of the heel piece of the one-piece cover is cut and a new heel spot made of the same material of the outer cover is inserted with hard plastic pins, in normal (18) or special height (18a). (17).

The heel is also to be manufactured in such a way that the sleeve around the heel core is sprayed with a slight layer on the lower surface of the core, and that the heel spot is mounted separately. The heel spot is also made of the same material as the outer shell and is embedded in the actual heel with hard plastic pins (17a). The non-elastic pins are foamed after the heel spot has solidified or inserted into the mold before the spraying process.

The fashionable appearance of the outer cover is achieved by coloring the material of the soft outer cover or an additional material is applied to the outer side walls of the heel.

All heels can be made as an independent part (19) or together with the sole as a unit (20). The material of the sole can be made of consist of the same material of the paragraph or a different material.

The differents forms out of the inelastic core to the lower surface, are: 1. a parallel conical taper (21) to the outer, higher side of the elastic outer sheath (2a), 2. own koni¬ specific rejuvenation ^'üngung (21a) and the third concave Taper with convex bulge (21b). With all forms of the heel, the height of the centerpiece can be shifted up or down to the surfaces, depending on the use (15, 15a).

By inserting the core into the mold prior to the injection process, it is achieved that the shrinkage points on the finished heel are avoided, which easily result when an independent casing is sprayed.

The outer, higher outer wall or cover is also clamped during assembly (3d).

This measure ensures that when wearing elegant footwear with an increased, slender heel shape, a relief of the intervertebral disc, hips and joints is achieved and the high energy savings make a contribution to maintaining health and performance.

The cover can be removed or fixed by a loose or firm connection to the hard core. The repair is made possible by attaching a new sales mark or by removing the entire casing. Leg length regulation can be carried out without difficulty by applying the correspondingly high heel spots. Due to the extremely simple manufacture, which is so inexpensive to manufacture due to its possible variations that sales can be used in all price groups of shoes. An embodiment is explained with reference to Figures 1 to 18.
