Figure 2 is an exploded perspective view showing a high heel according to a first embodiment of the present invention, Figure 3 is a side view showing a coupling state of FIG. High heels 100 according to the first embodiment of the present invention is largely as shown in Figures 2 and 3, the sole 110, the pivot shaft 120, the heel heel 130, the elastic member 140 and the auxiliary elastic member And 150. The sole 110 and the heel heel 130 are made of hard synthetic rubber or synthetic resin, which is commonly used for high heels.

Sole 110 is composed of a bottom portion 111 and the inclined portion 112 is inclined from the bottom portion 111 to be in contact with the ground, as in the conventional general high heels. At this time, the inclined portion 112 has a slightly slower inclination than the rear side where the heel is located. The upper surface 102 of the sole 110 is formed to surround the wearer's foot. Meanwhile, the sole 110 has a pair of pivot shaft support parts 113 protruding to support both ends of the pivot shaft 120 at the middle of the lower surface of the inclined portion 112. At this time, the rotation shaft support portion 113 may be properly positioned on the inclined portion 112 in consideration of the height of the heel heel 130 is designed, the separation space between the heel heel 130 and the sole 110. In addition, the pivot shaft support part 113 may be formed to be integral with the heel guide part 116 to be described later, as shown in FIG. 2.

Both ends of the pivot shaft 120 are inserted into and supported in the through holes 113a formed in the pivot shaft support 113, and are fixed to the pivot shaft support 113 by being screwed into the pivot shaft fixing member 122.

The heel heel 130 has a pivot shaft insertion hole 134 is formed in the front upper end portion 131, the front upper end 131 is hinged to the pivot shaft 120 has a foldable structure. At this time, the top surface 132 of the heel heel 130 has a gentle bend so as to be in close contact with the rear side lower surface 112a of the inclined portion 112. In addition, the heel heel 130 is in an extended state, that is, when the upper surface 132 is spaced apart from the rear lower surface 112a of the inclined portion 112 by a predetermined angle α, the front lower surface of the inclined portion 112. A locking surface 138 in contact with 112b is formed at the front upper end portion 131. As a result, the heel heel 130 may be folded within a predetermined angle α based on the unfolded state. At this time, it is preferable that the predetermined angle α forms approximately 10 ° to 45 °. On the other hand, the heel heel 130 is provided with a heel 136 to be in contact with the ground at the lower end, the heel 136 has a curved shape of the front side so as to be in continuous contact with the ground as it is folded from the expanded state.

The elastic modulus of the elastic member 140 may be appropriately selected in consideration of the impact absorption rate of the high heel 100.

Looking at the structure of the elastic member 140 according to the present embodiment in detail, as shown in Figure 2 extending from the torsion coil spring 142 and the torsion coil spring 142, respectively, to form a predetermined angle (α) It consists of a sole support 144 and a heel support 146. Torsion coil spring 142 is fitted to the pivot shaft 120, the sole support 144 and the heel support 146, respectively, the rear side lower surface 112a and the top surface of the heel 130 of the inclined portion 112 It extends from torsional coil spring 142 to support 132. At this time, the sole support 144 and the heel support 146 has a "c" shape. On the contrary, the elastic member 140 may be made of a leaf spring in which the sole support 144 and the heel support 146 are integrally formed. Therefore, the heel heel 130 described above is in an unfolded state spaced apart by a predetermined angle α in a state in which the elastic force of the elastic member 140 is released.

Meanwhile, the sole support part accommodating groove 114 is formed at the rear side lower surface 112a of the inclined part 112 of the sole 110, and the heel support part accommodating groove 133 is formed at the top surface 132 of the heel heel 130. Is formed. That is, the elastic member 140 may be more firmly fixed by receiving the sole support 144 and the heel support 146 in the sole support receiving groove 114 and the heel support receiving groove 133, respectively.

The auxiliary elastic member 150 is made of a material having an elastic force such as synthetic rubber, and has a plate shape. In addition, the auxiliary elastic member 150 is bonded to the rear lower surface 112a of the inclined portion 112 or the upper surface 132 of the heel heel 130. When the heel heel 130 is folded to touch the rear lower surface 112a of the inclined portion 112 to assist the shock absorbing function of the elastic member 140, it is to prevent the noise is generated.

Meanwhile, the high heels 100 according to the first embodiment are designed to form an acute angle with the ground in the unfolded state as shown in FIG. 3. That is, the conventional general high heels take a form different from having a heel heel perpendicular to the ground. The high heels 100 according to the first embodiment may implement a new type of design in accordance with the needs of consumers who pursue unique and individual designs.

Hereinafter, the operation of the high heels having the foldable heel according to the first embodiment of the present invention having the configuration described above with reference to FIGS. 4 to 6 will be described.

4 illustrates an initial landing state of the high heels 100 when walking with high heels. The high heels 100 are in an unfolded state because they are not under load before landing. Then, when landing, the heel 130 is in contact with the ground before the bottom 111. The heel heel 130 begins to elastically fold in the direction of the arrow as the load of the pedestrian is gradually loaded. At this time, the heel 136 having a curved shape allows the heel 130 to be naturally folded while maintaining a constant contact area with the ground. Therefore, the high heel 100 is the impact force received by the heel heel 130 in the initial landing state is converted to the elastic force of the elastic member 140, the impact at the time of landing is absorbed. In addition, the heel heel 130 is not only prevented from being easily damaged, there is an advantage to enable natural walking.

Next, FIG. 5 illustrates the medium landing state of the high heels 100. As the load of the pedestrian is loaded, the heel heel 130 is completely folded, and the maximum load of the pedestrian is supported by the bottom 111 and the heel heel 130 of the high heel. At this time, the load of the pedestrian is distributed to the bottom 111 and the heel 130 as shown by the arrow shown in the drawing. Since the heel heel 130 forms an acute angle with the ground, the heel heel 130 receives less load of the pedestrian than the conventional high heel, thereby improving durability of the high heel 100. In addition, due to the effect of lowering the height of the heel heel 130 there is an advantage that can prevent the pedestrian from spraining the ankle.

Finally, Figure 6 shows the late landing state of the high heels 100. As shown in the figure, as the load of the pedestrian moves to the heel, the rear side of the high heels 100 is lifted. At this time, the heel heel 130 is unfolded in the direction of the arrow by the elasticity of the elastic member 140.
