Heel Capable of Absorbing Shock for Footwear}

The present invention relates to a shoe heel, and more particularly, to a shoe heel that absorbs an impact applied to a foot, and more particularly, to a shoe heel that can cushion and damp a shock more flexibly.

Shoes vary greatly depending on their use and function. Among them, high-heeled heels make them look taller, smaller, and thinner, but they are more preferred for women. Deforms and toes, causing pain in the legs, causing a number of side effects.

Moreover, unlike other shoes, the heels of the heels are generally made of a hard material, which does not act as a shock absorber.

Accordingly, high heels have been proposed with a shock absorbing structure added to the heel, and examples thereof include 'shock absorbing structure of women's high heels' of the Korean Utility Model Registration No. 20-0169388 (published on February 15, 2000).

However, the shock absorbing structure of the elastic spring method applied to the conventional shoe heel including high heels has a limit that can not flexibly absorb the shock applied to the foot because the elastic spring acts rigidly in one direction.

In addition, the conventional shoe heel, such as high heels are practically no function to mitigate the shock applied to the foot in the lateral direction.

An object of the present invention is to cushion and dampen an impact applied to a foot through the heel of a shoe by providing a heel for a shoe that can absorb the shock more flexibly.

An object of the present invention is to provide an impact to a foot by mounting an elastic spring in a heel so as to overcome the limitation that the elastic spring acts rigidly in one direction with respect to a conventional shock absorbing heel that absorbs an impact. It is to provide a shock absorbing heel for shoes that can be more flexibly cushioned and damped.

The object of the present invention is that the use of high heels is suitable for applying to the heels of the high heels serious side effects as compared to other shoes, it is possible to more flexibly cushion and dampen the impact to the foot by the heels of the high heels It is to provide a shock absorbing heel for high heels.

It is an object of the present invention to provide a shoe heel which can absorb a shock applied in the transverse direction.

According to the invention, there is provided a shock absorbing heel for a shoe mounted on the heel of the shoe.

The shock absorbing heel for shoes according to the first embodiment of the present invention is a shock absorbing heel for shoes mounted on a heel of a shoe, and includes a support heel, an elastic heel, a support, an elastic spring, a diaphragm, beads, and a cushion member. .

Therefore, the shock absorbing heel for shoes according to the present invention has the effect of more flexibly cushioning and damping the shock applied to the foot when the shoes are worn. Particularly, when the heel of the present invention is applied to high-heeled high heels It is expected to be useful for solving the problem.

Hereinafter, with reference to the accompanying drawings will be described in more detail the shock absorbing heel for shoes according to the present invention. The following embodiments are merely illustrative of the shock absorbing heel for shoes according to the present invention, and are not intended to limit the scope of the present invention.

The heel 1 according to the invention is a heel that is mounted on the heel 3 of the shoe 2 and is particularly suitable for use as a heel of a high heel.

As shown in Figs. 1 to 4, the heel 1 of the present invention according to the first embodiment is a single article as a whole, but is structurally and functionally supported heel 10, elastic heel 20, support ( 30), the elastic spring 40, the diaphragm 50, the first beads (60a) and the cushion member 70 is configured to include.

The support heel 10 is a main part for holding the heel 1 of the present invention on the heel 3 of the shoe 2, and the nail and the adhesive on the heel 3 of the shoe 2 like the normal heel. It is firmly fixed by using.

The inside of the support heel 10 is not filled, but is a hollow chamber 11, and the entrance and exit hole 12 is formed through the lower surface 10a, that is, the lower surface of the chamber 11.

The elastic heel 20 is inserted into the up and down holes 12 of the support heel 10 so as to be movable up and down, and together with the support heel 10 to form the overall height of the heel 1 of the present invention. When the gong 22 is applied to the heel, the gong 22 is attached to the lower end of the elastic heel 20.

In the up-and-down movement in the state where the elastic heel 20 is inserted into the entry and exit hole 12 of the support heel 10, in the illustrated embodiment, the expansion and heel 20 is inserted into the entry and exit hole 12 during the vertical movement of the expansion heel 20 and The contacting waist portion 23 has a size corresponding to the diameter of the entry and exit hole 12, and the upper and lower portions except the waist portion 23 are larger than the diameter of the entry and exit hole 12, the entry and exit hole 12 By showing the restraint of the waist 23 by the elastic heel 20 is shown an example to be restrained up and down to the support heel 10.

Preferably, the size of the stretched heel 20 is such that its diameter (the heel of the present invention does not have to be circular in cross section, but is expressed as a diameter for convenience) is such that the diameter of the support heel 10 is not smaller than that of the support heel 10. Steps on the connecting portion of the elastic heel 20 and to minimize.

The support heel 10 and the elastic heel 20 are made of a high strength material such as high strength plastic or metal that can withstand the load of the wearer.

The support 30 is a pillar member extending from the upper surface 10b of the support heel 10 toward the lower surface 10a, and supports the elastic spring 40 to be described later.

The support 30 has a length such that the lower end of the support 30 does not reach the upper end of the stretched heel 20 to be spaced a predetermined distance when the stretched heel 20 is inserted into the support heel 10 as much as possible.

The elastic spring 40 is inserted into the circumference of the support 30 to apply an elastic force toward the extension heel 20 is drawn out from the support heel 10. To this end, the upper end of the elastic spring 40 is fixed to the upper surface 10b of the support heel 10 or the upper end of the support 30, but the lower end of the elastic spring 40 is the elastic heel 20 is supported at the support heel 10 When it is pulled out as much as possible, it is extended to apply a slight elastic force to the upper end 21 of the elastic heel 20. Therefore, when the load of the wearer applied to the heel 1 of the present invention is removed, the elastic spring 40 applies the elastic force to the elastic heel 20 inserted into the support heel 10 to draw out the elastic heel 20 as much as possible. .

The diaphragm 50 is attached to the upper side 21 of the elastic heel 20 and the side surface 10c of the support heel 10 adjacent thereto so that the chamber 11 is connected to the upper chamber 11a and the lower chamber 11b. It is partitioned and made of elastic material. The diaphragm 50 is formed of an elastic material in order to prevent the presence of the diaphragm 50 from hindering the vertical movement of the elastic heel 20. Thus, the diaphragm 50 is formed of a material that does not break despite the stretching that continues during the life of the heel without disturbing the stretching of the expansion heel 20.

The lower chamber 11b of the chamber 10 has air vented into a gap between the inlet / outlet 12 and the waist 23, but the upper chamber 11a is filled with the beads 60. .

The beads 60 function to cushion and dampen the shock absorption of the elastic spring 40 when the elastic spring 40 absorbs the shock applied to the elastic heel 20.

Beads 60 is a granular member having strength and durability that is not easily broken even when colliding with the upper end 21 of the elastic heel 20, etc., preferably a spherical or elliptic spherical shape (eg, roughly grained rice). High strength ceramic beads, for example, have an average diameter on the order of 0.1mm to 2mm.

Ceramic beads 60 which are preferably applied to the present invention, 'the method of manufacturing small ceramic beads' of Republic of Korea Patent No. 0026141 (August 15, 2000), Republic of Korea Patent No. 10-0522460 (2005) 10. 19. can be manufactured by a variety of methods and devices applying the 'small ceramic beads molding apparatus', etc., and can be purchased by applying beads having physical properties suitable for the purpose of the present invention.

The beads 60 filled in the limited volume of the upper chamber 11a are pressurized by the upper end 21 of the elastic heel 20 as the elastic heel 20 is inserted into the support heel 10, where the beads ( 60) buffers and attenuates the load applied to the stretchable heel 20 in the same manner as buffering and damping an impact when an object falls into a bag filled with sand.

As the elastic heel 20 moves up and down, the beads 60 are exerted with an external force, so that the arrangement is changed. The upper chamber 11a filled with the beads 60 is a limited space, so the beads It is not possible to effectively accommodate the arrangement change of (60).

The cushion member 70 is a configuration for accommodating the arrangement change of the beads 60, the cushion member 70 is mounted on the upper chamber (11a) is mounted on top of the beads 60, stretch When the beads 60 relieve and attenuate the impact applied to the heel 20, the change in arrangement of the beads 60 is elastically accommodated.

That is, when the elastic heel 20 is raised to press the beads 60, the cushion member 70 contracts to accommodate the change in arrangement of the beads 60, and conversely, the elastic heel 20 is lowered and the beads ( If the 60 is not pressed, the cushion member 70 expands to accommodate the arrangement change of the beads 60.

When walking with the shoe to which the heel 1 of the present invention is applied according to the first embodiment, the impact applied to the foot by the load applied to the heel 1 of the present invention is primarily applied to the elastic spring 40. The beads 60 are subjected to friction resistance (the frictional resistance between the beads and the frictional resistance between the beads and the support heel and the expansion heel) to the elastic heel 20 (particularly the head) inserted at the same time, Eventually, the beads 60 buffer and damp the shock absorption of the elastic spring 40 that acts rigidly in one direction, thereby allowing the heel 1 to absorb the shock more flexibly.

As shown in Figs. 5 and 6, the heel 1 according to the present invention of the second embodiment is a heel mounted on the heel 3 of the shoe 2, like the heel of the first embodiment, the upper heel ( 80), the lower heel 90 and the beads 60.

The upper heel 80 is a part mounted on the heel 3 when the heel is divided into two upper and lower parts, and the lower heel 90 is below the upper heel 80 at the heel separated into two upper and lower parts. This part is located in.

According to the features of the second embodiment, the upper heel 80 and the lower heel 90 are coupled to each other, so that the lower heel 90 moves with a play in the transverse direction with respect to the upper heel 80, the upper heel 80 The lower heel 90 is assembled to the uneven fit.

In the illustrated embodiment, an unevenness 81 is formed on the lower surface of the upper heel 80, and correspondingly, an unevenness 91 is formed on the upper surface of the lower heel 90. When fitting 91) is an example of the projections to each other to prevent the lower heels 90 to fall down against the upper heels (80).

In forming the unevenness (81, 91) in the upper heel 80 and the lower heel 90, the size of the unevenness is a gap (4) is formed in the uneven fitting assembly when fitted to the lower to the upper heel 80 The heel 90 is able to move in a transverse direction with a certain width (gap), wherein the beads 60 are filled in the gap (4) that generates the play.

Beads 60 of the second embodiment also function the same as the beads of the first embodiment. That is, the shock absorbing and attenuating effect generated in the transverse movement of the lower heel 90 relative to the upper heel 80.

Separately assembled upper heel 80 and the lower heel 90 assembly portion is preferably applied to the sealing material 5 of the elastic material to block the leakage of the beads (60).

As described above, in the second embodiment of the present invention, the heel 1 is divided into the upper heel 80 and the lower heel 90, while the upper and lower heels 80 and 90 are fitted with irregularities to have a transverse play. By assembling and filling the beads 60 in the gap 4 of the uneven fitting assembly, when walking and wearing the shoe to which the heel 1 of the present embodiment is applied, the shock applied to the transverse direction is the upper heel ( It is absorbed by the transverse movement of the lower heel 90 relative to 80 and the action of the beads 60 filled in the gap 4.

FIG. 7 applies both the configuration of the first embodiment and the configuration of the second embodiment to one heel so that the heel 1 of the present invention can alleviate and damp the transverse impact as well as the longitudinal direction.

In this way, when the heel structure of the first embodiment and the heel structure of the second embodiment are applied to the heel of the shoe, the longitudinal and lateral shocks applied to the foot through the heel when walking are effectively cushioned, so that high heels such as high heels It can significantly eliminate the inconvenience of shoes.

The oil 61 may be mixed with the beads 60 in the upper chamber 11a and the gap 4. The oil 61 is to provide fluidity that may be lacking in the beads 60 that are solid. As the oil 61 which can be applied, oil widely used for various hydraulic actuators such as a hydraulic cylinder can be used.

The mixing ratio of the oil 61 to the beads 60 may be selected in the range of 5: 1 to 1: 5, preferably 1-3: 1 by volume ratio, for example. In this case, if the content of the beads 60 is too high, the lubrication action of the oil 61 is insufficient and the fluidity thereof is too low, and if the content of the beads 60 is too low, the desired beads 60 The frictional resistance by) may be insufficient.
