Description

  The present invention relates to an antistatic work boot made of a conductive material in a heel part and a shoe sole, and a method for manufacturing an antistatic work boot.

  For example, it is necessary to prevent dust and dust from being generated in a clean room such as a semiconductor manufacturing factory. Therefore, work shoes used in clean rooms have anti-static properties (electrostatic properties) in the soles, insole and heel (top) of the work shoes in order to prevent the generation of static electricity. It is constituted by. Examples of such antistatic work shoes include antistatic work boots having a cover portion formed so as to cover the lower part of the heel so that the upper edge is located slightly below the heel, and the upper edge. There are anti-static work boots and the like in which the heel portion and the leg trunk portion are formed so that the heel portion and the leg torso are in an arbitrary position between a position slightly above the heel and below the knee (for example, Patent Document 1). In particular, the latter antistatic work boots can prevent dust and dirt caused by clothes by placing the user's (wearer's) clothes in the antistatic work boots. It is spreading. As such an antistatic work boot, there is one in which a leg trunk (cylinder part) made of polyester or the like is stitched on the outer side or the inner side of the upper edge of the cover part of the antistatic work boot.

Japanese Patent Laid-Open No. 10-155501 (FIG. 1)

  However, the conventional antistatic work boots have a problem that a gap (step) is formed near the joint portion between the cover and the leg trunk, and dust or dust such as dust tends to accumulate in the gap. is there. As a method of joining the collar part and the leg body part, there are a method of joining so that the leg body part is outside the sheath part, and a method of joining so that the leg body part is inside the sheath part. is there. In the antistatic work boots made by the former method, between the outer surface (outer side) near the upper edge of the heel part and the leg body part, in the antistatic work boots made by the latter method, A gap is formed between the inner surface (inner side) near the edge and the leg trunk. For this reason, the conventional antistatic work boots have a problem that dust and dirt are likely to accumulate in a gap formed near the joint portion near the upper edge of the hood.

  In addition, since anti-static work boots are used in clean rooms that do not like generation of dust such as dust, dust is usually washed about once a week in order to remove dust and dirt. . However, it is difficult to remove dust and dirt collected in the gap formed in the vicinity of the joints described above by washing, and conversely, dust and dirt may accumulate in the gap by washing. As described above, the gap formed at the joint between the rim portion and the leg trunk portion near the edge portion of the heel portion of the antistatic work boots is dust or dirt generated due to the antistatic work boots. It was the cause.

  The present invention has been made in view of the above-described problems, and does not have the gap as described above at the joint portion between the cover portion and the leg body portion, and has antistatic performance with excellent dustproofness. It is an object of the present invention to provide a method for manufacturing an anti-static work boot and an antistatic work boot.

[Antistatic work boots]
Hereinafter, an embodiment of the antistatic work boots of the present invention will be described with reference to FIGS. 1 and 2. The antistatic work boots of the present invention include, for example, antistatic work boots, antistatic work boots, antistatic work shoes having leg trunks, and the like.
FIG. 1 is a side view showing an antistatic work boot according to an embodiment of the present invention, and FIG. 2 is a state in which a part of the antistatic work boot shown in FIG. It is the side view which showed the inner surface of the antistatic work boots of FIG. 1 in the state which cut off one part.

  As shown in FIGS. 1 and 2, the antistatic work boots 10 of the present embodiment include a heel part (a heel part) 1, a toe reinforcement part 2, a torso part (leg torso part) 3, a pad part 4, and a mouthpiece. A throttle part 5, a shoe sole 6 and a fastener 7 are provided.

The heel part 1 is of a shape that is low enough to cover the part of the foot (foot) from the heel and cover the metatarsals and ribs of the foot, and is waterproof such as a synthetic resin material, a synthetic leather material, or a rubber material. It is made of a material with excellent properties. The collar part 1 is good also as comprising with the raw material (antistatic material) which has antistatic property. If the bottom surface 1a of the heel part 1 is made of an antistatic material (electrically conductive material), by forming the shoe sole 6 from an antistatic material, static electricity generated in the heel part 1 It is possible to discharge (ground) to the floor surface via the. Moreover, if the whole collar part 1 is comprised with an antistatic material, it will become possible to make the earth of the static electricity which generate | occur | produced in the collar part 1 more reliable, and to discharge in air | atmosphere.
Examples of the antistatic material include antistatic (conductive, conductive, electrostatic) metal fibers or conductive carbon black such as the above-described materials, such as metals such as copper and aluminum, or alloys containing them. A material in which an antistatic material such as powder or fiber is mixed can be used.
The toe reinforcement part 2 is for protecting the toe part of the foot covered by the heel part 1 from an external impact. The strength is necessary and sufficient to prevent the operator from being crushed and injury to the foot. However, the antistatic work boots 10 of the present invention are not necessarily provided with the toe reinforcement part 2 and may be configured not to have the toe reinforcement part 2.

The trunk | drum 3 wraps between a heel and a knee, and is comprised with the flexible cloth material which has antistatic property. Examples of the flexible cloth material having antistatic properties include, for example, a surface cloth in which fibers having antistatic properties such as carbon fibers are woven, or a material in which a surface cloth is bonded to a core cloth and laminated. Can do. More specifically, a dustproof fabric having an antistatic property, a dustproof fabric having an antistatic property, a back surface of a urethane sponge combined with a synthetic fiber, or a dustproof fabric having an antistatic property. A synthetic fiber mesh material bonded to the back surface of the substrate can be used.
Thus, since the trunk | drum 3 consists of the flexible cloth material (dust-proof cloth) which has antistatic property, it is hard to generate static electricity by friction etc. Therefore, the trunk portion 3 does not attract and adhere dust or dust due to the generation of static electricity, and is therefore particularly suitable for work involving clean rooms and clean rooms that are extremely hated from the presence of dust.
The antistatic work boots 10 of the present embodiment have a relatively short form in which the upper edge is in the vicinity of the heel and covers the heel, so the upper edge of the trunk portion 3 is in the vicinity of the lower part of the calf. It is the length which is located to the extent. When the antistatic work boots 10 have an upper edge located in the vicinity of the knee and cover the entire calf, the length of the torso 3 may be made to correspond to the length.

The pad portion 4 is formed inside the antistatic work boots 10 so as to cover the joint portion between the heel portion 1 and the trunk portion 3. Thus, by covering the gap formed by joining the heel part 1 and the body part 3 with the pad part 4, the heel part 1 and the body part 3 are integrated, that is, on the inner surface of the antistatic work boots 10. Since it can be made into the smooth shape in which the level | step difference is not formed in the junction part of the collar part 1 and the trunk | drum 3, it can prevent that the dust and dust resulting from the dust collected in the clearance gap generate | occur | produce in a clean room. .
The pad portion 4 is formed in a band shape along the inner surface of the upper edge portion of the flange portion 1 and is joined to the flange portion 1 and the trunk portion 3 on both sides of the band. As a result, the gap between the joints can be covered with the pad portion 4, and dust and dust can be prevented from being generated (dust-proof) from the gap corresponding to the covered gap. Thus, since the dust-proof effect by the pad part 4 is produced when the gap is covered by the pad part 4, it is not necessary to cover the entire gap by the pad part 4, and the labor required for manufacturing ( The optimal range should be covered in light of the relationship between the cost and the effect obtained. The material constituting the pad portion 4 may be a stretchable material excellent in cushioning properties (buffering properties). For example, a synthetic resin material or a synthetic leather material rich in stretchability can be used.

  The rubber pad (buffer material) 40 is provided between the heel part 1 and the pad part 4, and is covered with the pad part 4 inside the antistatic work boots 10. By providing a rubber pad 40 made of a stretchable material inside the pad portion 4, the comfort of the antistatic work boots 10 is improved, and fatigue of the wearer when worn for a long time is improved. Can be reduced. For example, when the work performed by bending the knee in the clean room is performed, the rubber pad 40 is provided, so that the antistatic work boots 10 are worn by the wearer (worker) along the upper edge of the heel part 1. ) And the feet in the anti-static work boots 10 can be prevented from floating from the bottom surface 1a of the heel part 1, so that operator fatigue can be reduced.

  The mouthpiece restricting portion 5 folds the trunk portion 3 at the upper edge of the trunk portion 3, puts an elastic material such as a rubber string in the folded portion, and puts the edge of the folded portion (the upper edge of the trunk portion 3 Is formed by sewing the body portion along the opposite side. With this configuration, the mouthpiece throttle part 5 expands and contracts within a certain range in the direction in which the diameter of the body part 3 expands and contracts. Thus, by providing the cuff throttle part 5 at the upper end of the trunk part 3, the wearer can easily move the foot 7 into the heel part 1 by opening the fastener 7, and the fastener In the state where 7 is closed, the mouthpiece throttle part 5 can be fitted to the leg. In addition, since the antistatic work boots 10 of this Embodiment are a thing of a comparatively short aspect, the upper edge, ie, the mouthpiece throttle part 5, fits a leg in the lower part of the calf of a leg.

  The shoe sole 6 is fixed to the bottom surface of the heel part 1. The method of adhering the shoe sole 6 and the heel part 1 may be either a method using adhesion using an adhesive or the like, or a method of integrally molding the heel part 1 and the shoe sole 6 with the same material. If the shoe sole 6 is made of an antistatic material, it can be discharged to the floor through the shoe sole 6 (grounding). Examples of the material having antistatic properties include, for example, antistatic metal fibers such as metals such as copper and aluminum or alloys containing them in the above materials or antistatic objects such as antistatic carbon black powders and fibers. Can be used.

  As described above, since the antistatic work boots 10 according to the present embodiment are configured to include a material having antistatic properties, static electricity generated in the human body and work clothes through the antistatic material is discharged into the indoor atmosphere. It can be discharged inside or on the floor. In addition, since the gap formed by the flange portion 1 and the body portion 3 is covered with the pad portion 4, the generation of dust and dirt from the gap can be prevented. Dust and dust in the gap are difficult to wash away by washing and conversely accumulate during washing. Covering the gap with the pad portion 4 is an antistatic work that is frequently washed. This is particularly effective for preventing the generation of dust and dirt due to the boots 10. Thus, the antistatic work boots 10 of the present embodiment are very suitable for use in a clean room or the like that performs work that dislikes the presence of dust and dirt.

[Method of manufacturing anti-static work boots]
Hereinafter, based on FIG. 3, FIG. 4, the manufacturing method of the antistatic work boots 10 mentioned above is demonstrated.
FIG. 3 is a front view of an essential part showing a manufacturing method of the antistatic work boots of the present invention, and FIG. 4 is cut along a portion indicated by a one-dot chain line AB in FIG. It is principal part sectional drawing which shows the manufacturing method of the antistatic work boots which show a cross section. In FIG. 3, the state corresponding to the sewing process of the pad part 4 is shown using (a), (b) and (c), and in FIG. 4, using (a), (b) and (c) in FIG. The state corresponding to each shown process is similarly shown using (a), (b) and (c).

  3 and 4 are both for explaining the first joining process for joining the body part 3 and the pad part 4 to (a), and (b) for the pad part in the first joining process. 4 is a view for explaining a second joining step for joining the body portion 3 to which the body portion 4 is joined and the flange portion 1, and (c) is a pad portion 4 to which the body portion 3 is joined in the first joining step. It is for demonstrating the 3rd joining process which joins and the collar part 1. FIG.

As shown in FIG. 3A, in the first joining step, the pad portion 4 is sewn in advance on the back side of the trunk portion 3 (the side that becomes the inside of the antistatic work boots 10 when worn). . More specifically, the end portion 3a of the body portion 3 on the side to be joined to the flange portion 1 and the end portion 4a on the one side of the pad portion 4 are combined (the end portion 3a and the end portion 4a substantially overlap each other). In this manner, the body portion 3 and the pad portion 4 are stitched together at the stitched portion 3c and the stitched portion 4c located about 5 mm from the end portion 3a and the end portion 4a.
FIG. 4A shows a state where the body portion 3 and the pad portion 4 are joined (sewn) by the first joining step described above. As shown in the figure, the body 3 and the pad 4 are stitched together by the stitching part 3c and the stitching part 4c so that the end part 3a and the end part 4a substantially overlap each other. The pad portion 4 is joined to the right side of FIG. At this time, the end portion 4 b opposite to the end portion 4 a of the pad portion 4 is in a free state that is not stitched to the heel portion 1.

FIG. 3B shows the body 3 viewed from the opposite side (opposite surface) to FIG. As shown in FIG. 3 (b), in the second joining step, the operation of sewing the trunk portion 3 on the back side of the heel portion 1 (the side that becomes the inside of the antistatic work boots 10 when worn) From the front side of part 1. Reinforcing tape 11 is previously sewed on the end portion of the flange portion 1 on the side to be joined to the body portion 3 so as to cover both sides of the body portion 3 near the end portion with a width of about 3 mm to 5 mm for the purpose of reinforcement. It has been. The body portion 3 and the heel portion 1 are joined at the stitching portion 11c on the reinforcing tape 11 so that the overlap between the heel portion 1 and the body portion 3 is about 5 mm. Since this joining (sewing) is performed from the front side of the heel part 1, the sewing operator can perform an operation of running the sewing machine while visually checking the reinforcing tape 11 and the sewing allowance C. For this reason, in the part reinforced with the reinforcing tape 11 of the collar part 1, the collar part 1 and the trunk | drum 3 are sewed together (docking sewing), and joining of the collar part 1 and the trunk | drum 3 is performed reliably. it can. In addition, since the edge part formed by the overlap of the collar part 1 and the trunk | drum 3 is covered with the pad part 4 later, and dust and dust do not accumulate, the overlap of the collar part 1 and the trunk | drum 3 is Even if it is not about 5 mm, it is sufficient if it can be covered by the pad portion 4 later.
FIG. 4B shows a state in which the heel part 1, the body part 3, and the pad part 4 are stitched by the second joining step described above. As shown in the figure, the heel part 1, the body part 3, and the pad part 4 are joined to each other at a stitched part 11 c formed so that the seam is positioned on the reinforcing tape 11 of the heel part 1. Thereby, joining of the collar part 1, the trunk | drum 3, and the pad part 4 can be made reliable and strong.
By joining the pad part 4 to the body part 3 in advance in the first joining process described above, in the subsequent second joining process, the opposite side of the surface where the collar part 1 is in contact with the body part 3 is obtained. It is possible to sew the body 3 from the surface to the heel 1, that is, the sewing operator can sew the heel 1 and the body 3 while looking at the reinforcing tape 11 from the front side of the heel 1. For this reason, the collar part 1 and the trunk | drum 3 can be sewn on the reinforcement tape 11, and joining of the collar part 1 and the trunk | drum 3 can be strengthened. In addition, by this stitching, the shoe pad pad portion 4 that has been previously joined to the trunk portion 3 in the first joining step can be joined to the collar portion 1 by the stitching portion 11c on the reinforcing tape 11. The problem when the conventional method is used will be described later.

FIG. 3C shows the body 3 viewed from the same side as FIG. As shown in FIG. 3C, in the third bonding step, the pad portion 4 is turned over, and is shown by a dotted line in FIG. 3C between the pad portion 4 and the back side of the flange portion 1. While inserting the rubber pad 40, the pad portion 4 is sewn to the heel portion 1 at the stitching portion 4d near the end portion 4b. By the third joining step described above, the joint portion between the flange portion 1 and the trunk portion 3 can be covered with the pad portion 4, and the flange portion 1 and the trunk portion 3 can be integrated.
FIG. 4C shows a state in which the flange portion 1 and the trunk portion 3 are integrated. As shown in the figure, the pad portion 4 is joined to the heel portion 1 and the trunk portion 3 at the stitching portion 11c, and the pad portion 4 covers the heel portion 1 and the trunk portion 3 at the joint portion. And the rubber pad 40 arranged between the pad part 4 and the heel part 1 can make the antistatic work boots 10 have good fit and comfort.

  As described above, according to the manufacturing method of the antistatic work boots 10 of the present embodiment, the pad portion 4 is joined to the trunk portion 3 in advance in the first joining step, and then the bag is made. Since the 2nd joining process which joins the part 1 and the trunk | drum 3 can be performed from the surface side of the collar part 1, it joins (stitches) on the reinforcement tape 11 of the collar part 1, and implement | achieves reliable joining can do. And in the 3rd joining process made after the 2nd joining process, by joining pad part 4 joined to trunk part 3 to collar part 1, the joined part of collar part 1 and trunk part 3 Can be covered by the pad portion 4. Further, if the rubber pad 40 is inserted into the pad portion 4 in the third joining step, the cushioning property of the pad portion 4 can be improved and the comfort of the antistatic work boots 10 can be improved. it can.

[Conventional manufacturing method]
The problems that occur when the conventional manufacturing method is used will be described below. FIG. 5 is a main part front view showing a conventional method for manufacturing an antistatic work boot, and (a), (b), and (c) show the manufacturing method step by step in this order.
FIG. 5A shows a case where the body is formed on the inner side (back side) of the flange portion 101 by the second joining step shown in FIG. 3B without passing through the first joining step shown in FIG. The state which sewn the part 103 is shown. The docking sewing for docking the collar part 101 and the trunk part 103 is performed in a state where the reinforcing tape 112 is sewn to the end of the trunk part 103 on the collar part 101 side. And the trunk | drum 103 is sewn together with the collar part 101 in the stitching | suture part 111c in which a seam is located on the trunk | drum 103 near the reinforcement tape 112 so that the reinforcement tape 112 may be followed. For this reason, according to the conventional method, a gap is generated between the flange portion 101 and the trunk portion 103 (reinforcing tape 112). In FIG. 5A, a gap is formed between the back portion 101 of the reinforcing tape 112 of the body portion 103. The accumulation of dust and dirt in this gap (step) contributes to dust and dirt generated in the clean room.

Therefore, in order to eliminate the step between the flange portion 101 and the body portion 103 at the joint portion and to integrate both, it is necessary to cover the step portion with the pad portion 104. In order to cover the step with the pad portion 104, it is necessary to sew the pad portion 104 to the trunk portion 103 along one edge thereof and to sew the pad portion 104 to the collar portion 101 along the other edge. In order to securely join the pad portion 104 to the body portion 103 by the former sewing operation, it is not sufficient to sew the pad portion 104 to the body portion 103, and the seam overlaps the body portion 103. It is necessary to pass over the reinforcing tape 111 that reinforces the end of the flange 101. However, when the pad portion 104 is sewn after the body portion 103 is sewn to the back side (inside) of the collar portion 101, the pad portion 104 is sewn from the back side of the body portion 103. When working from the back side of the body part 103, since the end of the collar part 101 is hidden behind the body part 103, the operator sews the pad part 104 while looking at the reinforcing tape 111 at the end of the collar part 101. It is not possible. Here, since the reinforcing tape 111 that reinforces the end of the collar portion 101 is usually formed with a very narrow width of about 3 mm to 5 mm, the seam is located on the reinforcing tape 111 from the back side of the body portion 103. It is very difficult to sew on.
Therefore, when the operator joins the pad portion 104 without looking at the reinforcing tape 111 of the collar portion 101 from the back side of the trunk portion 103, the stitched portion 104 c (formed on the pad portion 104 when viewed from the back side of the trunk portion 103. Even when the stitching portion 103c) has a straight and straight seam as shown in FIG. 5B, when viewed from the front side of the trunk portion 103 (the front side of the collar portion 101), the stitching portion 103c As shown in FIG. 5C, the (sewn portion 104 c) is formed by undulation so as to go back and forth between the reinforcing tape 111 of the collar portion 101 and the trunk portion 103. As a result, the pad portion 104 is easily sewn to the heel portion 101 and the trunk portion 103, and there arises a problem that an antistatic work boot having a sufficient function cannot be manufactured.

  On the other hand, in the manufacturing method of the antistatic work boots of the present invention described above, the pad portion 4 is sewn to the trunk portion 3 in advance before the second joining step for stitching the heel portion 1 and the trunk portion 3 is performed. By attaching (see FIGS. 3 and 4), the operator can sew the collar part 1 and the body part 3 while looking at the reinforcement tape 11 from the front side of the collar part 1, so that the reinforcement tape 11 can be easily The collar part 1 and the trunk part 3 can be sewn so that the seam is located at the bottom. By this stitching, the pad portion 4 can also be joined to the heel portion 1. That is, the point of the present invention is that it includes a first joining step in which the shoe pad pad portion 4 is sewn to the heel portion 1 in advance. Accordingly, it is possible to sew the three cloths, that is, the heel part 1, the body part 3, and the shoelace pad part 4 by the same method as the sewing of the two cloths. In addition, according to a sewing method using a normal sewing machine that is currently used, it is not possible to sew three pieces of cloth apart. For this reason, when not using the 1st joining process which sews the pad part 4 to the trunk | drum 3 previously, the brim part 1, the trunk | drum 3, and the pad part 4 are bonded by adhesive etc. in these edge vicinity. An operation of pasting in advance is required. However, such work is not realistic and is almost impossible.

  INDUSTRIAL APPLICABILITY The present invention can be used as an antistatic work boot suitable for work in a clean room or the like and a method for manufacturing an antistatic work boot that prevent generation of dust and dust.
