{IMPROVED DUST PROOF SHOES FOR CLEAN ROOM}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a room air conditioner for a clean room, and more particularly, to a room air conditioner having an ergonomic structure capable of improving comfort.

A clean room is a place where manufacturing of sensitive parts such as semiconductors and sensitive to the environment of the room is performed, and it is a working space where temperature, humidity, etc. are suitably man- ufactured and controlled in accordance with work processes and always maintained cleanliness.

In the FAB process performed in such a clean room, the dust generated in work clothes or shoes affects the parts to be manufactured. Therefore, workers in the clean room must wear the dustproof clothing and the fire protection inevitably.

Generally, in a clean room, a firearm worn by a worker is made of a material which does not generate static electricity due to the motion of the human body, and includes an upper which forms a space for receiving a foot, And a tight contact portion surrounding the calf portion. Techniques related to fire retardation are disclosed in Korean Patent Laid-Open Publication No. 2006-0046838 and Laid-Open Patent Publication No. 2001-0106026.

Japanese Laid-Open Patent Application No. 2006-0046838 discloses a sole for preventing the inner circumferential surface of the workpiece from coming into direct contact with the foot and improving the comfort and sweating by flowing air, A shoe upper having an air pad on its inner circumferential surface, and a tight fitting portion provided on an upper portion of the shoe upper to closely contact the calf.

Japanese Patent Laid-Open Publication No. 2001-0106026 is directed to minimizing the occurrence of accidents during the handling of heavy objects while being free from the effects of static electricity or dust in the workplace. A protective member for reinforcing the inner ceiling portion is provided on the inner front portion of the spark- And a protector that protects the heel of the foot is attached to the outer rear portion of the foot body, so as to protect the toe and the heel.

However, in the conventional spark arrester, the bottom of the sole which is joined to the lower part of the shoe upper, that is, the surface of the insole which directly contacts the sole of the human body in the sole has a simple flat structure, There is a vulnerability that is easily floating on the upper surface and is not comfortable to wear.

In addition, the conventional spark arrester has a structure in which a surface of an outsole contacting the ground surface of the sole is flat or a groove of a predetermined pattern is simply formed, so that when the forefoot is broken during walking, There is a problem in that a countermeasure is required.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a radiological apparatus for a clean room having a structure in which a foot of a human body is prevented from flowing to the insole,

It is another object of the present invention to provide a radiological apparatus for a clean room having a structure in which the resistance to the feet of a human body is alleviated from the outsole to improve the comfort.

In order to accomplish the above object, the present invention provides a surgical instrument comprising: an epidermis forming an internal space for receiving a foot of a human body; And a bottom portion coupled to a lower portion of the epidermis and having an insole providing a support surface for the foot of the human body and an outsole contacting the ground, wherein the support surface of the insole is centered at both widthwise edges The present invention provides a clean room fire protection system having a concave rounded structure.

The supporting surface of the bottom portion preferably has an arch structure.

Preferably, the outsole is formed with a plurality of bending grooves having at least three or more multi-tier structures extending at least in the transverse direction.

Preferably, the multi-layered structure having three or more layers is formed so as to gradually narrow the width of the inside of the groove for bending.

It is preferable that the interval between the adjacent bending grooves is gradually widened from the inside to the outside of the main ignition.

Preferably, an air hole may be formed in the heel of the bottom part.

The air hole may be communicated from a side of the heel to a lower portion of the insole.

The insole is preferably made of a breathable material.

The present invention may further include a tightening part extending from the upper part of the skin to cover the calf of the human body.

It is preferable that the periphery of the upper end opening of the tight contact portion is made of a cloth material having a larger number of layers than the other portions.

Preferably, the epidermis includes a support strap corresponding to the feet side of the human body and extending in the direction toward the upper end of the epidermis, wherein a plurality of the epidermis are arranged in the longitudinal direction to inhibit lateral movement of the foot.

And the maximum spacing between the plurality of support straps is gradually increased toward the rear of the spark arrester.

According to the present invention, since the structure of the insole is improved so as to have a round-shaped support surface, the sole of the human body can be stably held, so that the sole is prevented from flowing, thereby improving the comfort.

In addition, according to the present invention, a groove having a multi-layered structure of three or more layers formed on the outsole can relieve the resistance to the foot during walking by the operator, thereby improving the wearing comfort.

Further, the support strap contained in the skin of the cap prevents the lateral movement of the feet, and the breathability is imparted to the insole, thereby providing a comfortable feeling of comfort.

Therefore, when the present invention is applied, there is an advantage that it is possible to implement a vibration prevention having a comfortable wearing feeling as well as a sports walking, while having a dustproof function that can be used for working in a clean room.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary terms, and the inventor should appropriately interpret the concepts of the terms appropriately It should be interpreted in accordance with the meaning and concept consistent with the technical idea of the present invention based on the principle that it can be defined. Therefore, the embodiments described in this specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, It is to be understood that equivalents and modifications are possible.

FIG. 1 is a perspective view showing an appearance of a fire extinguisher for a clean room according to a preferred embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along line A-A 'of FIG. 1 in detail.

1 and 2, a clean room ventilator according to a preferred embodiment of the present invention includes a cap skin 100, a bottom 110, and a tight fitting part 120, And the support surface 111a provided in the main body 111 is substantially concave.

The skin 100 is processed in such a form as to cover the feet of the human body to form an internal space for receiving the human feet. It is preferable that the material of the cape skin 100 be made of a dense material so that the dust generated in the feet of the human body does not scatter to the outside of the fire extinguisher.

A plurality of support straps (101) are provided at portions corresponding to the feet on both sides of the human body in the skin of the cape. The support strap 101 is elongated in the direction toward the upper end of the carapace, that is, the portion corresponding to the upper end of the foot of the human body, while a plurality of the support straps 101 are arranged at predetermined intervals in the longitudinal direction of the diaphragm to support both sides of the foot, As shown in FIG.

It is preferable that the maximum spacing between the plurality of support straps 101 is gradually increased toward the rear end of the main span so as to eliminate the inconvenience caused by the depression when the foot is broken during walking. For example, W1, W2, W3, and W4 corresponding to the maximum of the intervals between the support straps 101 may be arranged in the order of 1.0 cm, 1.1 cm, 1.2 cm, and 2.3 cm, respectively.

The bottom portion 110 is coupled to the lower portion of the carapace 100 and has an insole 111 that provides a supporting surface 111a for the foot of the human body and an outsole 112 that touches the ground.

The support surface 111a of the insole 111, that is, the upper surface thereof, is rounded to have a substantially concave shape centering at both edges of the insole 111 in the width direction. According to such a configuration, the sole of the human body does not flow to the support surface 111a but is closely contacted to provide a sense of stability and balance, thereby achieving a remarkable effect that the feeling of fit can be improved.

Considering a transverse arch structure formed on the sole portion of the human body, it is most preferable that the supporting surface 111a of the insole 111 has an arch structure in terms of improving the wearing comfort. In the arch structure of the support surface 111a, when both ends of the arch structure are raised up to an angle range of not more than 5 degrees with respect to the ground surface, the effect of preventing the side surface from being slipped is remarkable,

The insole 111 may be detachably coupled to the upper portion of the bottom portion 110 or may be attached by sewing or the like to be integrated with the bottom portion 110.

In addition, it is preferable that the support surface 111a of the insole 111 has a shape in which both ends of the insole 111 in the longitudinal direction are raised upward with respect to the ground surface. According to this configuration, it is possible to prevent the foot from being pushed forward or backward from inside of the spark arrester. Especially, when the front end portion of the support surface 111a of the insole 111 has a structure that is raised up to an angle range of 5 degrees or less with reference to the ground surface, the anti-skid effect is remarkable.

As shown in FIG. 3, the outsole 112 has a banding groove 113 having a multistage structure in the thickness direction of the bottom portion 110. The banding groove (113) provides a function that the anti-vibration can be comfortably bent when the forefoot of the human body is broken at the time of walking. To this end, the banding grooves 113 are formed to extend in a straight line or a curved shape in the lateral direction of the outsole 112, and a plurality of the grooves 113 are repeatedly formed along the longitudinal direction of the outsole 112.

In addition, as shown in FIG. 3, the outsole 112 further has grooves extending in the longitudinal direction so as to penetrate the plurality of bending grooves 113, thereby further enhancing the bending performance.

It is desirable that the width of the outsole 112 in Fig. 3 is configured to be larger than that of the existing spark to provide a comfortable fit. For example, the width of the outsole 112 may be configured such that the maximum of the front half portion is about 10.5 cm and the maximum of the back half portion is about 9.0 cm.

As shown in FIG. 4, the banding grooves 113 are formed in a stepped shape so as to have at least three layers of multi-layered structures 113a to 113c while decreasing their width gradually as they go inward. According to this configuration, when the forefoot of the human body is tilted during walking, a remarkable effect can be obtained in which the anti-vibration can be flexed while minimizing the resistance to the feet.

The spacing between the adjacent bending grooves 113 is gradually widened from the inside toward the outside of the main span so as to minimize the resistance factor caused by the outsole 112 when the foot is tilted when walking, desirable. That is, as shown in FIG. 3, W6 located outside is relatively larger than W5 located relatively inward with respect to the width direction of the main ignition.

It is preferable that air holes 114 are formed in both sides of the heel of the bottom portion 110 to provide a more comfortable cushion feeling when walking. Although not shown in the drawing, the air hole 114 may extend to the rear portion of the rear foot so as to have a substantially U-shape. Further, it is preferable that the air hole 114 is communicated from both sides of the heel to the lower portion of the insole 111. According to such a configuration, the insole 111, which is preferably made of a breathable material, is in direct contact with the air hole 114, so that the air permeability can be further improved.

In addition, it is preferable that a predetermined heel count is applied to the heel portion to protect the ankle.

In addition, it is preferable that a mesh-like cloth material is applied to the entire inner surface of the spark arrester so that sweat is effectively absorbed when moving, thereby improving comfort and comfort.

The adhered portion 120 is extended upward from the upper end of the cape skin 100 to cover the calf of the human body, thereby preventing scattering of dust. Preferably, the adhered portion 120 is made of a cloth material, and in particular, the perimeter 120a of the top opening is made of a cloth material having a larger number of layers than other portions. That is, when the tight contact portion 120 is formed of a single layer of cloth material, the upper opening perimeter 120a is made of, for example, two layers of cloth. According to this configuration, the dust scattering upward from the inside of the tight contact portion 120 can be effectively blocked by the dustproof structure of at least a double layer formed in the upper opening perimeter 120a.

In the clean room fire fighting as described above, since the soles of the foot are stably and balancedly adhered by the insole 111 having the round-type support surface 111a when the operator wears it, flow is prevented, thereby providing a comfortable fit .

In addition, at the time of walking of the operator, resistance to the feet can be alleviated by the bending grooves having at least three layers formed in the outsole 112 and the air holes 114 formed in the heel of the bottom portion 110, It is possible to alleviate the impact feeling and the fatigue which are applied to the feet.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not to be limited to the details thereof and that various changes and modifications will be apparent to those skilled in the art. And various modifications and variations are possible within the scope of the appended claims.
