Description

The present invention relates to clothes for preventing electric shock that protects a wearer's body from electric shock.
In this specification, the term “insulation” refers to electrical insulation and electrical insulation.

  Heretofore, at work sites where there is a risk of electric shock hazards, work has been carried out by wearing insulating clothes made of insulating materials in order to ensure the safety of workers. Such insulation clothing has a thicker fabric material than general work clothing in order to ensure electrical insulation that can be used safely against high voltages of several thousand volts. For this reason, the mobility of the operator was significantly reduced.

  A material with withstand voltage is used as an electric shock prevention clothing corresponding to the poor workability that is the problem of the conventional insulation clothing, and it is an insulation equipped with a work clothing provided with a ventilation part etc., and a main body formed by vacuum molding processing. Clothes have been proposed (see, for example, Patent Documents 1 and 2).

  On the other hand, clothes using conductive materials are also known as clothes for preventing electric shock (see, for example, Patent Document 3). Here, as in the case of the insulating clothes, the ease of work is an important point, and clothes for preventing electric shock that are easy to move are also proposed (see, for example, Patent Document 4).

  In the case of insulating clothing, the higher the voltage, the thicker it becomes. If you wear such insulation clothes and accidentally come in contact with the charging part during work, although the insulation property is secured but the ground current does not flow, the electric path of the charging part will not be interrupted and it will be charged and it will be dangerous. .

  On the other hand, if clothes using a conductive material are worn like the clothes for preventing electric shock described in Patent Documents 3 and 4, the electric path of the charging unit is cut off even if the charging unit is accidentally touched. Although it is superior to insulation clothes, there is room for improvement in terms of securing the safety of the wearer's human body by using the conventional conductive material for preventing electric shock.

  An object of the present invention is to provide an anti-electric-shock-resistant clothing which can prevent a wearer's electric shock or reduce damage to a human body at the time of an electric shock.

  The present invention is an electric shock preventing garment in which the entire surface layer is formed of a conductive material except for a specific range of the front body, wherein the specific range of the surface layer is formed of an insulating material, and the specific area The range is a position and a size that can cover a predetermined range centered on the heart in front view when worn.

  The electric shock-proof clothing of the present invention is characterized in that the size of the specific range is 5 to 10 times the size of the heart in front view.

In the clothes for preventing electric shock of the present invention, the specific range is a rectangular shape, and the position and size of the specific range are as follows in front view when worn.
(1) In the vertical direction, the upper side is the position of the clavicle, and the lower side is the position 30 cm from the upper side.
(2) The lateral direction is 15 cm to the right and 25 cm to the left with respect to the center line of the body.

  Further, in the clothes for preventing electric shock of the present invention, the material of the clothes for preventing electric shock is made of a single layer, and the whole single layer is the surface layer.

  Further, in the clothes for preventing electric shock of the present invention, the material of the clothes for preventing electric shock has a double-layered structure of two or more layers, and the outer layer of the multiple layers is the surface layer.

  According to the present invention, it is possible to provide a shockproof clothing that can prevent a wearer's electric shock or reduce damage to the human body at the time of a shock.

It is an external view of the clothes 1 for electric shock prevention of 1st Embodiment of this invention. It is the state figure which wore the electric shock prevention clothes 1 of FIG. It is an external view of the clothes 2 for electric shock prevention of 2nd Embodiment of this invention.

  FIG. 1 is an external view of the electric shock-preventing clothing 1 of the first embodiment of the present invention, and FIG. 2 is a state diagram of the first embodiment of the electric shock-preventing clothing 1 worn. In FIG. 1 and FIG. 2, a dot is attached to a specific range 31 of the front body 22 for easy understanding.

  The electric shock protective clothing 1 is a full-body integrated work clothing that prevents the wearer 101 from an electric shock or reduces the damage to the human body at the time of an electric shock. The form of the shockproof clothing 1 is the same as a conventional full-body integrated workwear in which a hood 11 for covering the head, an upper garment 12 for covering the upper body, and a lower garment 13 of a pants type covering the lower body are connected. The upper garment 12 includes a sleeve 21, a right front 22a, a left front 22b, and a back 24. The right front 22a and the left front 22b are openably connected by fasteners 25.

  The electric shock preventing garment 1 has a feature which is not in the prior art in the configuration of the front body 22 (22a, 22b), and more specifically, the configuration and arrangement of the material of the front body 22. Although the electric shock preventing clothing 1 is characterized by the composition and arrangement of the material of the front body 22, it has the same flexibility and flexibility as the conventional whole-body integral type protective clothing, and also the mobility of the wearer 101 There is no significant decline.

  The whole of the electric shock preventing clothes 1 including the hood 11, the upper coat 12 and the lower coat 13 is made of a material of a two-layer structure of a surface layer (outer layer) 51 and a back layer (inner layer) 53. The entire surface layer 51 is made of a conductive material except for the specific range 31 of the left and right front bodies 22. On the other hand, the entire back layer 53 is made of an insulating material. The specific range 31 of the front body 22 is a predetermined range centering on the heart when the electric shock preventing garment 1 is worn.

  The magnitude of the damage caused by the electric shock is greatly affected by the magnitude of the current and the duration of the current, but even a slight current can cause death if it strikes the heart directly. In addition, if a current higher than the ventricular fibrillation current flows in the heart, the patient will die from electric shock, so it is necessary to prevent the current higher than the ventricular fibrillation current from flowing in the heart even when the charging unit is accidentally touched. .

  The electric shock preventing garment 1 uses the entire surface layer 51 as the conductive material except for the specific range 31 of the front body 22, and the ground fault current makes the surface layer 51 even when the wearer 101 accidentally contacts the charging portion. Make it flow. On the other hand, the specific region 31 of the front body 22 is made of an insulating material so that the ground current does not flow in the vicinity of the heart of the wearer 101.

  The human heart is the anterior lower part of the mediastinum in the thoracic cavity, and is located to the left but approximately in the center, and the size is said to be about the size of a fist. In order to prevent the ground current from flowing near the heart of the wearer 101, it is preferable to set the size of the specific range 31 of the front body 22 to about 5 to 10 times the size of the heart.

  In the clothes 1 for preventing electric shock, the specific range 31 of the front body 22 has a rectangular shape and is set so as to be in the following range in front view when worn. In the longitudinal direction of the specific range 31 of the front part 22, the upper side 32 is the position of the clavicle, and the lower side 33 is the position of 30 to 30 cm from the upper side. The lateral direction is 15 cm in the right direction and 25 cm in the left direction with respect to the center line of the body. That is, the right side 34 is 15 cm from the center line, and the left side 35 is 25 cm from the center line O. If the specific range 31 of the front body 22 is rectangular, manufacturing including sewing is facilitated.

  The surface layer 51 excluding the specific range 31 of the front body 22 is entirely formed of a conductive material. The conductive material is not limited to a specific material as long as it has conductivity enough to flow ground current.

  Examples of the conductive fabric include conductive fibers in which non-conductive fibers are coated with metal plating or the like, conductive metal wires, and fabrics containing metal fibers. Examples of conductive fibers in which non-conductive fibers are coated with metal plating etc. include chemical fibers such as cotton and polyester, and non-conductive fibers such as blended yarn of cotton and chemical fibers, such as gold, silver and copper. The thing coated by plating etc. is mentioned. Examples of the conductive metal wire and metal fiber include stainless steel, copper, aluminum, silver, metal wires including these alloys, and metal fibers.

  The surface layer 51 excluding the specific range 31 of the front part 22 may be replaced by a conductive cloth, and a known conductive sheet or conductive non-woven fabric may be used.

  The material of the specific range 31 of the front body 22 is made of an insulating sheet. The insulating sheet only needs to have the ability to shut off the ground current sufficiently, and is not limited to a specific sheet. The material of the specific range 31 of the front body 22 is, instead of the insulating sheet, an insulating fabric or insulating non-woven fabric formed of fibers coated with polyvinyl chloride on the surface of chemical fibers such as polyester. You may use it.

  The back layer 53 is made of a fabric having excellent insulating properties as a whole. Although the back layer 53 and the specific range 31 of the front body 22 both have insulation properties, the materials used therein may be the same or different.

  The surface layer 51, the specific range 31 of the front body 22, and the back layer 53 are sewn and joined. The bonding of the surface layer 51, the specific range 31 of the front body 22 and the bonding of the back layer 53 is not limited to sewing but may be an adhesive depending on the materials of the surface layer 51, the specific range 31 of the front body 22 and the back layer 53. Adhesion by welding, welding, or a combination thereof can be used.

  Since the entire surface layer 51 is made of a conductive material except for the specific range 31 of the front body 22, the electric shock preventing garment 1 having the above configuration is a case where the wearer 101 erroneously contacts the charging portion, However, the ground fault current flows through the surface layer 51 of the electric shock prevention clothing 1. At this time, since the insulating material is disposed on the surface layer 51 and the insulating material is disposed on the back layer 53 in the vicinity of the heart of the wearer 101, a ground fault current flows near the heart of the wearer 101. Can be prevented. Thereby, the wearer 101 can be prevented from electric shock or damage to the human body during electric shock can be reduced.

  In addition, the electric shock preventing clothes 1 have the same degree of flexibility and flexibility as conventional full-body integrated protective clothes, and are easy to use because they do not significantly reduce the mobility of the wearer 101.

  It is possible to work more safely if the lower coat portion 13 of the electric shock preventing clothes 1, for example, the hem 14 and the ground 201 are connected by a ground wire (not shown) when the electric shock preventing clothes 1 is worn it can. Other methods may be used for the short circuit to the ground 201 of the clothes 1 for preventing electric shock. The electric shock prevention clothes 1 may be worn on top of normal work clothes.

  FIG. 3 is a diagram showing a configuration of the electric shock prevention garment 2 according to the second embodiment of the present invention. The same code | symbol is attached | subjected to the structure same as the electric shock prevention clothes 1 of 1st Embodiment of this invention, and description is abbreviate | omitted. In FIG. 3, a dot is attached to a specific range 31 of the front body 22 for easy understanding.

  The clothes 2 for preventing electric shock are upper garments (outerwear). Similar to the electric shock preventing clothes 1, the electric shock preventing clothes 2 are also worn at the time of work to prevent the wearer 101 from electric shock or reduce damage to the human body at the time of electric shock. The basic form of the shockproof clothing 2 is the same as that of the conventional workwear, and has the same flexibility and flexibility as the conventional workwear.

  Similar to the electric shock preventing clothes 1, the electric shock preventing clothes 2 are also characterized in the material configuration and arrangement of the front body 22. The electric shock protective clothing 1 uses a material having a two-layer structure of a surface layer (outer layer) 51 and a back layer (inner layer) 53 as the material, but the electric shock protective clothing 2 is a single layer, and the left and right front body The whole is made of a conductive material except for 22 specific ranges 31.

  The material of the shockproof clothing 2 is configured in the same manner as the surface layer (outer layer) 51 of the shockproof clothing 1, and the specific areas 31 of the left and right front body 22 are also specific to the left and right front body 22 of the shockproof clothing 1. The same material, size, and arrangement as the range 31. If necessary, it can be considered that only the upper coat portion 12 is taken out of the electric shock preventing clothes 1 and the back layer 53 is removed. In the present embodiment, the electric shock preventing clothing 2 made of a single layer material is shown, but as in the electric shock preventing clothing 1, a material having a two-layer structure of a surface layer (outer layer) 51 and a back layer (inner layer) 53 is used. It is possible.

  Unlike the electric shock preventing clothes 1, the electric shock preventing clothes 2 are not provided with the pants (the lower coat portion 13) and the hood 11 unlike the electric shock preventing clothes 1. Therefore, the electric shock proof 2 is basically worn with conductive pants (not shown), a helmet and a conductive helmet cover (not shown). At this time, in order to flow the ground fault current to the ground 201, it is necessary to electrically connect the shockproof clothing 2 and the conductive pants, and the shockproof clothing 2 and the conductive helmet cover.

  For this reason, a conductive connector 61 for connecting to the conductive pants is attached to the electric shock preventing clothes 2 in the vicinity of the lower end. The connector 61 is composed of a conductive connecting band 62 and a conductive metallic suspender clip 63. The upper end of the connecting band 62 is sewn to the electric shock proof 2 and the suspender clip is connected to the lower end of the connecting band 62. 63 is attached. The conductive connector 61 may have another structure as long as it can be easily attached to and removed from the pants, and the clip may be another form of clip.

  When using the protective clothing 2, the conductive clip of the conductive connector provided on the conductive helmet cover is held by the suspender clip 63 and the conductive clip of the conductive helmet cover is also used for the protective clothing 2. Attach to the collar 15. Thereby, a helmet cover, the electric shock prevention clothes 2, and pants are electrically connected. The usage procedure of the shockproof clothing 2 and the function and effect of the shockproof clothing 2 are basically the same as the shockproof clothing 1.

  As described above using the clothes for preventing electric shock according to the first and second embodiments, the clothes for preventing electric shock according to the present invention can be used via the clothes for electric shock prevention even if it is accidentally in contact with the charging unit during work. Since it causes a ground fault, it can prevent the wearer 101 from an electric shock, or reduce the damage to the human body at the time of an electric shock, and can prevent a serious accident such as a current flow near the heart and death. In addition, compared to insulating clothing, there is no decrease in mobility when worn, and since a ground fault current flows easily, an operation of a relay that automatically cuts off the electric circuit can be expected.

  The clothes for preventing electric shock according to the present invention are not limited to the clothes for preventing electric shock of the first and second embodiments, and can be changed and used without changing the gist. Although the specific range 31 of the front body 22 is rectangular in the first and second electric shockproof clothings 1 and 2, the present invention is not limited to the rectangular shape. In the first embodiment, the material has a two-layer structure. However, the material may have a three-layer structure or a four-layer structure. In this case, the outer layer is formed entirely of conductive fabric except for the specific range 31 of the front part 22.

  While the preferred embodiments have been described above with reference to the drawings, those skilled in the art will readily recognize various changes and modifications within the obvious scope in view of the present specification. Therefore, such changes and modifications are interpreted as being within the scope of the invention defined by the claims.
