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).

The present invention relates to the heel of shoes worn by men and women. In particular, the present invention relates to a shoe heel in which the heel of the shoe is in the form of a high heel or a conical wedge according to the fashion, and the shock is relieved when the heel is raised.

The present invention can bring about the best effect, especially for flat sport shoes. In other words, when the foot is double buffered action is less force on the human body, the impact load on the ankle joint is significantly reduced.

The top and bottom of the shoe heel of the present invention is closed, and the inside of the heel is made of wood or hard synthetic resin material without elasticity and elasticity, and contains a solid core made of hollow or hollow, so it is firm and stable. The heel envelope is made of soft elastic material and acts as a cushioning element. This is registered in the German design, ie G 9201.107.1 and German Patent No. p 42 19 15.1. PCT / DE 92/00563, Design Registration G 92 09 230.6. Design Registration G 92 09 302.9. PCT / DE 92/00845, etc.

Conventionally, a flat, wide and low heel is provided which cushions the bottom of the shoe proposed in German patent application DE 29 33 393, where the core is soft It is made of elastic material. The outer shell is closed at the bottom, made of a single body, and is made of elastic synthetic resin or rubber to impart buffering force.

In addition, the outer wall of the heel becomes a spring element, and the empty space inside the heel contains a cushioning element made of a foam material or a soft synthetic resin having a large self-buffering force.

In addition, there is an additional coil spring to play a buffer role. Here, the shell can also be a spring element, with the core as a cushioning element. This core has the same degree of elasticity as the outer spring element, and under the unloaded condition the same height as the spring element, but under the load the shell and the core are equally compressed. This allows the shell to squeeze to where it is deep under load.

However, when the heel is raised so that the tip of the heel is thin and the bottom surface is small, the core made of the soft elastic material will not have stability. This is because the core and the outer shell are made of soft ingredients, and the strength of the foot when it is tipped causes the thin heel to bend.

The height of the core made of soft elastic material is equal to the height of the shell of soft elastic material. Therefore, walking will not be maintained properly here.

German patent application DE 29 08 023 relates to a heel to be fashioned and shows a composite of several wedge-shaped pieces. The conical intermediate layers are made of a resilient material and are fixed at the upper and lower contact surfaces. And almost the same thickness throughout the heel cross section.

It is an object of the present invention to provide a shoe heel having sufficient elasticity and allowing the horizontal deformation of the lower heel to occur only within a very limited range. However, in order to achieve this purpose, the first and second segments face each other at both contact surfaces, the first segment is obliquely going from the top to the bottom in the traveling direction, and the second section is obliquely from the bottom to the opposite. In the prior art, since the heel has to be made up of a number of pieces to fit this method, the pieces are allowed to flow and friction over time due to deactivation and decompression. The structure has a problem in durability and a high cost.

In the heel described in patent number DE 23 12 038 C 2, a generally firm gap is attached to the inside of the heel of the contact surface with the ground, and a wedge-shaped cushion that is spring-pressed to the outside of the heel is attached. This wedge-shaped cushion spans the entire length of the heel, tapering toward the side that crosses the inside of the heel.

This feature of the heel constitutes a wedge-shaped cushion with the outside of the heel higher than the inside so that the top of the heel is at an acute angle to the contact surface with the ground when not under load, and the top of the heel touches the ground when under load The wedge-shaped cushion is compressible by the wearer's weight until it is generally parallel to the face. Such wedge-shaped cushions may protrude sideways convexly beyond the edges and joining surfaces of the face contacting the ground by compression.

The heel is flat and wide. This heel structure is not suitable when the height of the heel is more than 3 cm. Because in this case, the wedge shape is too narrow to cause a bonding action.

Therefore, an object of the present invention is to improve the shape of the conventional heel so that the surface of the heel contacting the ground is relatively small, the height is high and thin, but the stability of walking is secured and the cushioning effect is high.

In addition, the present invention constructs and manufactures the heel according to the present invention on the basis of the proper synthesis and combination of materials in the desired shape and better technical embodiment, and also develops the components of the materials to be advantageous in terms of manufacturing cost. There is also a purpose.

In order to achieve the above object, the present invention allows the top and bottom of the relatively high heels or conical wedge-shaped heel 22 to be closed (7), the elastic shell (6) formed in a single body and the core without elasticity ( It consists of 1). In addition, the object of the present invention can be achieved by using the outer cover 6 made of a stretchable synthetic resin or rubber material 4 as a cushioning element. The essence of the shoe heel according to the present invention is to arrange the stabilizing element and the cushioning element with a suitable material component so that the synthesis and placement of the material can be effective.

The object of the present invention is realized with the following configuration. In order to explain this, an embodiment according to the drawings will be described below.

That is, the heel of the present invention, which has a height of high heels or conical wedges, is composed of two different materials, and the top and bottom of the heel of the shoe are closed (7), and the length and width vary. In addition, the rigid and unstretched cores (1) made from cold wood or hard synthetic resin material (12) or hollowed (12a) are used as stabilizing elements, and the flexibility of the shore hardness can change. The outer shell 6 using the elastic outer shell 6 of the rubber material 4 as a cushioning element is, for example, polyurethane, terminal rubber, thermoplastic rubber, or other soft synthetic resin material that may change shore hardness. It is made of monolith.

In this way, the heels can be vertically squeezed with elasticity in their longitudinal axis. This part, which resiliently relieves the weight of the load when walking the loin, is a non-elastic core when not loaded. It is higher than (1) (7a).

The soft envelope may have different shapes depending on the shape of the solid core, which has its maximum thickness from the bottom (5), from the top (5a) and from the side (5b), respectively. The heel can be of various heights, depths, and shapes. The sole 17 of the heel is injection-molded to be integral with the wall of the shell 6, or separately made for assembly, and the leg length with the special height 18a when repaired to the normal height 18 as shown in FIG. It can be prepared for adjustment. It is made of the same material as the outer shell, which is fitted with one or several pins of hard synthetic resin material which are inserted into the preliminary hole 17a at the bottom of the core when repaired. The resilient core 1 and the soft shell 6 are tightly matched to each other on the inner wall.

The outer wall is determined by a mold prepared for injection molding. By changing the shape of the upper and outer edges of the core (1a · 16: the upper outer edge (1a) of the core is rounded off) 1b · 16a: the outer edge (1b) is formed in an acute or right angle bracket. 1c: The entire upper surface of the core is formed flat 1d · 16b: The upper outer edge of the core is formed flat 1d) The effect obtained is as follows.

First, the edges of the outer shell (16: bent round. 16a: bent at right angles or acute angles. 16b: flatly in contact with the core) are arranged in accordance with the core shape (1a, 1b, 1c), respectively. ), The heel can be removed from the upper (3), and then the outer shell (6) can be removed. Second, the outer shell snaps together with the core (1d) with the upper edge flat. ), So that the sheath can be removed without having to remove the entire heel from the upper. The outer shell is secured to the upper together when assembled. The shell 6 can be inserted into the core 1 in one work step, or the core 1 is placed in a mold prior to the injection molding process. The core 1 and the shell 6 are not firmly engaged 6a. Heels are attached to the upper of the shoe with screws, glue, nails (3) or compression pins (13) and nails or other methods. In this case, closing the upper heel on the upper side is achieved by the upper surface 2 of the core and the upper side wall 2a of the shell contacting the upper 3.

When a heel with a closed lid 9a or a locking nipple and a lid 9 which can be closed as a groove is produced, the rigid core 1 has one surface that is flat (1c) in its entirety, and The side wall 2a of the shell comes into contact with the upper 3 to close the heel 3b. The combination of the core 1 and the shell 6 is loose (6a) or firm (8a) depending on the application. The shell 6a fitted to the core is carried out separately in one work step, or is made by putting the core 1 into the mold before injection molding. Attaching the heel to the upper can be done using screws and nails (3) or other means, where the screws and nails (3) penetrate through the soft shell portions (9, 9a) serving as the core cover and into the solid core (1). Enter In order to stabilize the screw 3, a ring 10 of metal or hard synthetic resin surrounding the screw is inserted into the hole of the cover. The cover shells 9 and 9a are adhered to the core 1 or are loosely attached. That is, the outer shell with cover is made in a state of not being combined with the core 6a so as to be loose in the entire inner wall, or the lid is firmly adhered to the upper surface of the core without the core being coupled with the inner wall of the side or the upper side. It is produced in the state 8a.

In the case of the rear axle without the curved shell edges 16, 16a and 16b and the cover shells 9 and 9a, the soft shell 6 is firmly joined to the hard core (8). Screws and nails are used to attach to the upper of the shoe. In this case, the closure of the heel is made by the upper surface 2 of the core and the side wall 2a of the upper side slightly raised (3c). All outer sidewalls of the heel have conical grooves (11) or no (14), as in Figures 12 and 13, depending on the application.

The cushioning effect is higher than without this groove line and soft heel cover. This is because the deformation of the material is pushed into the groove when stepping on, so that the pressure is softened and gives more leap when the pressure is released. The soft shell is taller than the hard core in the unloaded form in any variation (7a).

Depending on the application, even in variants where the outer edges of the shell are bent, the outer shell cannot be firmly coupled to the core at the sidewalls (8), and even with the lid, the outer shell is firmly coupled to the top of the core. There may be 8a.

Another variant of the heel, which has a monolithic outer shell 6 and a rigid core 1, described earlier, has not only a spare hole for the screw to secure the upper, but also for the case where repair is needed at the base of the core. The spare hole 17 is provided. When repairing, the heel sole part of the outer shell made of one piece is cut, and a pin made of the same material and made of hard synthetic resin fits the new heel sole, which is the normal height (18) or the special height (18a). It was made to have.

In addition, the outer shell is molded around the heel core so that the thickness of the outer skin layer of the bottom portion of the core is thin, and a heel that is made to attach a separately made heel sole can be made. Similarly, the heel sole is made of the same material as the outer shell and has a pin made of hard synthetic resin that can be fitted to the heel (17a).

These inelastic pins are lowered in the heel sole and then pre-saturated or pre-molded prior to injection molding. Coloring the soft skin material or coating additional material on the outer sidewalls of the heel can give the skin a fashionable appearance.

All types of heels may be made of a single piece 19 or may be made of a single piece 20 together with a shoe sole. The sole of the shoe can be made of the same material as the heel or a different material.

The shape of the inelastic core towards the bottom varies, firstly, as it is tapered into a cone parallel to the upper outer sidewall (2a) of the elastic shell (21) and secondly, as in FIGS. 5 and 10 (2). As in Fig. 7, it can be tapered into its own conical shape (21a), and as in Fig. 3, Fig. 6, and Fig. 8, it can be tapered as the core is penetrated inwardly so as to be convex (21b). In all types of heels, depending on the application, the position of the core can be placed close to the bottom 15 or the top 15a of the heel.

By inserting the core into the mold before injection molding, it is possible to prevent defects that are likely to occur when the skin is injection molded independently.

The upper outer sidewall or cover of the shell is tightly held together (3b) during assembly.

By using this method, you can reduce the impact on the disks, hips, and joints of the spine, and put less strain on the body when wearing stylish shoes with high and thin heel shapes, contributing to maintaining health and activity.

The sheath's sheath is loosely or firmly coupled to a solid core and can be detached or fixed. This can be done by attaching a new heel sole or replacing the entire skin. Leg length adjustment can be easily achieved by attaching a suitable height heel sole. The heel of the present invention can be produced in a variety of variations and can be made very simply at low cost and can be used in shoes of all prices.

EMBODIMENT OF THE INVENTION Hereinafter, one Embodiment of this invention is described based on attached drawing 1-18. In the figures, the heel is closed up and down (7), and a firm core (1) without elasticity and elasticity is used as a stable element. This core is made of solid synthetic resin or wood, either hollow (12) or hollow (12a), as shown in Figures 2 and 4. The upper surface of the core and the outer edges of the core form a variety of shapes (1a, 16: rounded ends, 1b, 16a: acute or right angled angles, 1c: the entire top of the core is flat, 1d, 16b: core The upper outer edge of the plate is obliquely flat). As the core descends toward the underside, the shape is also varied (21: tapered to a cone parallel to the skin, 21a: independent roux is also varied (21: tapered to a cone parallel to the skin, 21a: independent) Conical tapered, 21b: convex, convex, concave inward, tapered in. In the heel, the core is located close to the lower (15) or upper (15a) of the heel. A tough layer of soft material surrounds the core (4) and an envelope (6), which acts as a cushioning element and is higher than the inelastic core without load (7a) and in the form of a hard core. Correspondingly, its maximum thickness is taken at the lower 5, upper 5a, or side wall 5b areas, where the outer shell is loosely embedded in the core or the inner wall of the outer shell is not firmly coupled to the core. The sieve may be loose (6a), the core may be firmly coupled to the entire sidewall of the shell, and the top of the core may be firmly coupled to the inner wall of the sheath, but the side and bottom of the core may not be joined to the shell. The outer shell has a lid which can be closed (9) or closed (9a), which has a fixing ring surrounding the fixing screw (3).

At the upper end of the side wall of the shell is bent the edge according to the shape of the core (16: rounded, 16a: bent or right angled, 16b: snap lock). The outer surface of the outer sheath may have a groove line (11) or may not (14). The heel may be provided separately with a heel sole that is a repair part having a normal height (18) or a special height (18a) (17a), or a heel sole formed in an injection molding process together with the lower outer wall of the shell (6). (17). There are spare holes in the upper and lower parts of the core. The sole and the heel of the shoe are each formed of independent parts (19). It may also be formed as a single body (20).

The upper surface 2a of the upper outer wall of the shell is attached to the shoe upper by screws, nails, adhesive 3 or pressing pins and nails 13. The closure of the heel is made by the upper surface (2) of the core and the upper side wall (2a) of the shell contacting the upper (3a, 3c). The cover shells 2, 9 and 9a and the side walls 2a come into contact with the upper. These heels are relatively high in height and have the form of narrow heels or conical wedges (22). The upper sheath or cover sheath of the heel is tightly held together (3d) at the time of assembly.
