Description

Heel reinforcement shoes

The present invention reinforces the mounting structure of the detachable member 100 that is replaceably mounted on the heel body 200 of the shoe so as to be integral with the shoe as well as the durability of the detachable member 100 to be replaced when worn or damaged. It relates to a heel reinforcement structure shoes that also improved the durability of the impossible heel body 200.

Footwear with protruding lower heel is classified into various types such as shoes, dress shoes, high heels, shoes, and boots according to the use or shape, and the bottom of the heel which is easily worn by touching the ground is formed by a detachable heel member. It is also manufactured to be used only by replacing parts.

Looking at the removable heel member as shown in the Patent No. 10-1017789, a groove is formed in the bottom surface of the heel, the fixing pin is installed on the upper surface of the heel member, inserting the fixing pin into the groove to insert the bent member in the heel I can fix it. When the bent member is worn, the fixing pin may be pulled out of the groove to remove the bent member and install a new bent member. Therefore, the shoes can be worn for a long time only the easily worn heel member is replaced.

However, as the heel is formed of a hard synthetic resin material, the contact surface with the heel member, that is, the bottom of the heel may be worn. This is because the bent member is fixed to the heel by the fitting of the groove and the fixing pin, but the upper surface of the heel member and the bottom of the heel are in surface contact, so when a strong shock is applied to the heel member when walking shoes, The contact surface may be worn, especially the edges.

In addition, since the heel member is made smaller and thinner than the heel in order to emphasize the curvature of the heel of the shoe, the heel member is not worn from the bottom that touches the ground, but is easily damaged when subjected to a strong impact, and thus has to be frequently replaced.

Moreover, if a shoe is scratched in a heel that is difficult to replace because it is fashion-sensitive, such as a dress, the shoe will not be used for a long time as a new shoe is purchased for the desire to replace the shoe.

On the other hand, the applicant of the present invention patented the heel member to move the heel to touch the ground up and down in the configuration of the heel member detachable to the heel but to incorporate a buffer member to mitigate the shock applied to the heel with a buffer member Registered Patent No. 10-1201844. According to this, the detachable structure of the heel member forms a groove in the heel and forms an insertion portion (component corresponding to the fixing pin of Patent No. 10-1017789) on the upper surface of the heel member for insertion fixing. Not only can the easily be worn or easily damaged heels be removed and replaced from the bent member, but also the cushioning member, which has a reduced buffering capacity with prolonged use, can be easily removed and replaced from the bent member. The replacement also provides a cushioning shoe that can be used for a long time at low cost while partially replacing a component of the heel member that is easily removable to the heel.

However, Patent No. 10-1201844, to which the applicant of the present invention is registered, also has a structure for inserting and fixing a protrusion of the heel member in the groove of the heel in the same manner as the Patent No. 10-1017789 described above, and wears shoes. If you look at the bottom and corners of the heel there is a risk of easy wear or breakage, replaceable heel member was also likely to be easily broken.

Furthermore, as the heel member is detachably installed, cracks (outer traces of the contact portion) appearing as scratches appear on the site where the heel member is installed, which makes it difficult to see the overall shape of the heel.

The heel body 100 has a groove 110 is formed deep from the bottom, starting from the bottom, by inserting the insertion portion 210 protruding to the upper portion of the detachable member 200 to be described later into the groove 110 to remove the removable member ( After the 200 is mounted, it can be removed if necessary.

Looking at the specific shape of the groove 110, it is reduced than the lower space portion 111 and the lower space portion 111 formed on the lower side so that the lower step 115 is formed on the boundary between the lower space portion 111 The upper space portion 113 is formed on the upper side so that the bottleneck space portion 112 of the intermediate portion is formed, and the upper stepped portion 114 is formed on the boundary with the bottleneck space portion 112 to be larger than the bottleneck space portion 112. Has

At this time, in the first embodiment of the present invention, the upper space portion 113 is formed to penetrate the upper surface of the heel body 100, so that the groove 110 is formed to penetrate the heel body 100 up and down Is done. Accordingly, when the sole 3 is allowed to penetrate the position of the upper space 113 and the rear of the insole 2 can be lifted, the heel 100 is fixed to the rear bottom surface of the sole 3. In the long bolt 240 to be described later can be inserted through the upper space 113.

The detachable member 200 is inserted into and fixed to the groove 110 of the heel body 100 so that the detachable member 200 is detachably inserted into the heel body 100. The upper contact surface 220 is formed around the part 210 and is in close contact with the bottom surface of the heel body 100, and the heel window 250 directly contacts the ground.

In the first embodiment of the present invention, the detachable member 200 is provided with an inner space 217 having a lower opening, an interlocking elastic member 230 in the inner space 217, and separately manufactured the heel 250. After the upper portion of the heel 250 is inserted into the inner space 217 at the lower side to receive the elastic force by the elastic member 230 to move up and down like a piston.

When the detachable member 200 is viewed in shape, the upper surface of the heel protection jaw 221 is formed as the upper contact surface 220 by forming the heel protection jaw 221 extending outward from the lower end of the insertion part 210. do. Here, the heel protection jaw 221 is in close contact with the bottom surface of the rim forming the periphery of the inlet 110 of the heel body 110 to protect the heel body 100 does not directly touch the ground.

In addition, the insertion portion 210 is formed on the hollow large diameter portion 211 and the large diameter portion 211 inserted into the lower space 111 of the groove 110, the bottleneck of the groove 110 It is composed of a hollow small diameter portion 212 is inserted into the space portion 112, it can be inserted into the groove 110.

At this time, the small diameter portion 212 is provided with a fixing jaw 213 formed to protrude outward the upper end, and also provided with a slot-long groove 214 formed to be cut in the lower portion starting from the upper end of the groove 110, Since it is inserted while retracting when inserted into the bottleneck space 112, exerts an elastic restoring force to expand again and is in close contact with the bottleneck space 112, the fixed jaw 213 is locked to the upper stepped 114 It shall not fall unless it is forcibly removed.

In addition, the inner lower end of the small diameter portion 212 is in communication with the inside of the large diameter portion 211, the bolt head seating jaw 216 protruding inwardly is formed.

In the case of the large diameter portion 211, the inner step 215 is formed at the boundary between the large diameter portion 211 and the small diameter portion 212, so that the inside of the large diameter portion 211 is defined as the inner space 217. As the elastic member 230 is accommodated in the inner space 217, the upper portion of the elastic member 230 comes into contact with the inner step 215, and the heel 250 is inserted through the lower opening of the inner space 217. The upper surface of the elastic member 230 is applied to the elastic restoring force to push out when the heel 250 is pushed into the inner space 217.

In addition, the elastic member 230 is the first shock absorbing material 232 mounted to be in direct contact with the inner end 215 of the large diameter portion 211, and the compression spring erected vertically so as to contact the upper end of the first buffer material (232). 231 and a second shock absorbing material 233 which surrounds the compression spring 231 along the outer circumference thereof. Accordingly, when the compression spring 231 and the second buffer 233 is simultaneously contracted when compressed by the heel 250, the elastic restoring force generated in each of the compression spring 231 and the second buffer 233. The first shock absorbing material 232 is also contracted by the contraction of the compression spring 231 and the second shock absorbing material 233, and the elastic restoring force is exerted.

Accordingly, the elastic member 230 is a double buffering action by the compression spring 231 and the second buffer member 233 and a multi-stage buffering effect by the addition of the first buffer member 232, thereby compressing the compression spring 231. It is possible to distribute the impact and to extend the life of the compression spring 231 than to install alone. In addition, in order to allow the long bolt 240 to be described later to pass through the compression spring 231, the diameter of the inner passage cross section of the compression spring 231 is larger than the outer diameter of the long bolt 240, the second Since the buffer member 232 surrounds the compression spring 231, the compression spring 231 maintains the upright state stably, and prevents the compression spring 231 and the long bolt 240 from contacting each other.

Here, since the rear sole 250 should not be detached from the detachable member 200, the insert 251 having a female thread is embedded in the upper surface of the rear sole 250. Then, the bolt head 241 is formed at the top and the male bolt 242 is formed in the lower outer peripheral surface to a predetermined height to insert the long bolt 240 into the small diameter portion 212 to penetrate the first buffer member 232, After passing through the inside of the compression spring 213, the lower end is inserted into the insert 251 to be screwed.

At this time, since the bolt head 241 spans the bolt head seating jaw 216 of the small diameter portion 212, the heel 250 is after the long bolt 240 is screwed into the insert 251. It is not to be separated from the removable member 200. In addition, the fastening depth of the long bolt 240 and the insert 251, that is, the lower length of the long bolt 240 inserted into the insert 251 in the state that no external force is applied to the heel 250 At least a portion of the upper portion of the heel 250 is to be adjusted to maintain the inserted state in the interior space 217 of the detachable member 200. In addition, the size of the initial elastic restoring force may be changed by adjusting the screwing depth of the long bolt 240 and the insert 251. For example, the elastic restoring force of the elastic spring 231 has a linear characteristic in the contraction length, and thus, by adjusting the contraction length of the elastic spring 231 in the state without external force, You can change the size.

As described above, the

heel

100 and 200 are configured by the heel body 100 and the detachable member 200, and the long heel 240 is moved to the detachable member 200 to move the heel 250 up and down. After installation, the detachable member 200 is detachably mounted on the bottom surface of the heel body 100, and when the component of the detachable member 200 is worn or broken, the heel body detachable member 200 occurs. After disassembly from the (100) by disassembling can replace only the worn or damaged components can be mounted on the heel body 100 after assembly.

Furthermore, according to the present invention, the reinforcement frame 10 which protects the heel body 100 while protecting the detachable detachable member 200 from being worn or damaged is mounted on the detachable member 200.

The reinforcing frame 10 extends from the edge of the upper cover part 11 and the upper cover part 11 covering the upper contact surface 220 of the heel protection jaw 221 and bends downward as the heel protection jaw 221. Consists of the side cover portion 12 to cover the side of the), when mounted on the heel protection jaw 221 is to cover the edge at the edge of the upper contact surface 220 along the circumference.

In addition, by attaching the detachable member 200 mounted on the heel protection jaw 221 to the heel body 100 in this way, the upper cover part 11 of the reinforcement frame 10 is Interposed between the upper contact surface 220 of the heel protection jaw 221 and the bottom surface of the heel body 100 so that the upper contact surface 220 does not directly contact the bottom of the heel body 100, the reinforcing frame 10 The side cover portion 12 is bent downward from the edge side edge of the upper contact surface 220 to protect the side of the heel protection jaw 221.

In general, the heel is made of a hard synthetic resin material or because it is produced by pressing a multi-stacked leather laminated and then may be worn or damaged by an external impact, moreover, as in the present invention, the heel heel body 100 and the removable member 200 When the detachable member 200 is detachably mounted to the heel body 100, the detachable member 200 swings slightly with respect to the heel body 100 when subjected to external shock. Accordingly, the contact surface between the detachable member 200 and the heel body 100 is worn by the swing of the detachable member 200. On the contrary, according to the present invention, the upper cover part 11 of the reinforcing frame 10 is interposed between the bottom surface of the heel body 100 and the upper contact surface 220 of the detachable member 200 of the heel body 100.

In particular, when the heel 250 is strongly stepped on the ground with the heel or walked on the bumpy road enough to enter the inner space 217 of the detachable member 200, the heel protection jaw (221) may be damaged by hitting the ground Since the heel protection jaw 221 is protected by the reinforcing frame 10, the detachable member 200 may be used while only replacing the rear heel 250 which is easily worn or damaged. In addition, as shown in the figure, the reinforcing frame 10 is composed of the upper cover portion 11 and the side cover portion 12 is installed in the corner of the heel protection jaw 221, it is possible to attach and detach. Thus, the reinforcing frame 10 can also be used to replace when broken.

In the embodiment of the present invention, the reinforcing frame 10 is made of a metal material in order to minimize the wear of the heel body 100 and the wear or damage of the detachable member 200. This is because the metal material smoothes the surface to reduce the friction coefficient, and is higher than the heel body 100 and the detachable member 200 in strength.

In addition, since the side cover portion 12 of the reinforcing frame 10 is exposed to the outside, the reinforcing frame 10 is preferably coated in color, for example, gold plating in order to make the entire shape of the heel look beautiful. Looking at the heel before installing the reinforcing frame 10, the boundary line between the heel body 100 and the detachable member 200 is exposed to the outside so that the overall shape of the heel is not good, according to the present invention In installing (10), the shape of the heel can be made beautiful by installing the reinforcing frame 10 which can not be plated due to the characteristics of the material of the heel, but can be plated.

On the other hand, at least one notch (notch, 120) was formed at the lower end of the heel body 100. Here, the notch 120 is formed as a groove in the bottom surface of the heel body 100 has a form cut into a groove starting from the outer surface of the inner space 217 to the inner surface. If the thickness between the outer surface and the inner surface of the heeled body 100 is thick, starting from the outer surface and to the inner surface to be fired to a predetermined depth, but not to the inner surface in the form of grooves opened in the lower direction and the outer direction. Notch 120 may be provided.

Accordingly, when the detachable member 200 is mounted on the heel body 100, the upper cover part 11 of the reinforcing frame 10 is partially exposed to the lower portion of the notch 120, for example, a hook. When pulled downward into the notch 120, the detachable member 200 can be easily separated from the heel body 100. Here, the detachable member 200 is provided with the reinforcing frame 10 so that the hook is in contact with the top cover portion 11 of the reinforcing frame 10, the detachable member 200 is not damaged by the hook. Thus, in replacing the heel sole 250 that wear occurs most easily among the components of the detachable member 200, the heel sole 250 can be replaced without damaging the detachable member 200. The member 200 may be used for a long time.

In addition, the side cover portion 12 of the reinforcing frame 10 is mounted to protrude outward from the lower side of the heel body 100. In the embodiment of the present invention for this purpose, when the removable member 200 is mounted on the heel body 100 without mounting the reinforcing frame 10, the side of the removable member 200 and the side of the heel body 100 are smooth. After the detachable member 200 is manufactured to be continued, the reinforcing frame 10 is attached to the detachable member 200 so that the reinforcing frame 10 is lower than the heel body 100 by the thickness of the side cover part 12. It protruded outward from the side. Accordingly, although the reinforcing frame 10 does not cover the lower end of the heel body 100, but protrudes outward from the lower end of the heel body 100, the lower end of the heel body 100 even though the stone walks on the road. Can protect the In particular, by forming the groove 110 for inserting the insertion portion 210, the lower end of the heel 100 is easy to be damaged by an external impact, by installing the reinforcing frame 10, the heel 100 ) To protect the bottom.
