  However, in the conventional metal fitting 7, there is a possibility that the hook 55 of the body rope 53 may be erroneously locked in the through hole 700 formed in the base plate 70, and there is room for improvement. Note that such a problem is not limited to metal fittings for hanging a tool, but is a problem existing in all wearing tools in which a through hole for inserting a waist belt is formed.

  Therefore, it is an object of the present invention to provide a wearing tool which can prevent hooks of a torso from being accidentally locked and which can be mounted on a wearing tool including the torso and a waist belt.

A wearing tool that can be worn by a wearing tool including a torso and a waist belt of the present invention includes a waist belt to be wound around a person's waist, a torso having a hook at an end and wound around a pillar, and the waist. A belt is inserted and is configured to be attachable to a wearing tool provided with an annular locking ring capable of locking the hook of the torso, and an insertion hole through which the waist belt can be inserted is a direction in which the waist belt is inserted. A pair of mounting main body portions that are spaced apart and opposed to each other, and the mounting main body portion includes a plate-shaped main body portion and both end portions in the length direction of the main body portion, and A pair of mounting portions formed so as to stand upright, the insertion hole is formed in the mounting portion, and the dimension of the insertion hole in the plate thickness direction is the same as or substantially equal to the thickness of the waist belt. It is formed so as to have the same size, of the inner circumferential surface forming the insertion hole, the plate thickness direction Wherein the back toward the peripheral surface formed toward the Oite back is formed in the mounting portion.

In the wearing tool having the above configuration, the waist belt can be inserted into the pair of insertion holes in order, so that the wearing tool can be worn with the main body facing the surface of the waist belt. Here, since the size of the insertion hole in the plate thickness direction (the opening size in the plate thickness direction) is the same as or substantially the same as the thickness of the waist belt, the opening edge portion that defines the waist belt and the insertion hole. There is no gap (play) for accidentally locking the hook of the rope. Therefore, it is possible to prevent the hook from being accidentally locked to the wearing tool.
Further, in the present invention, the attachment portion extends from a lengthwise end of the main body portion to a back surface side in the plate thickness direction of the main body portion, and a back surface of the attachment portion itself and a back surface of the main body portion. It may be configured to have a rising portion formed such that the angle formed by is an obtuse angle.

  In the present invention, the attachment portion connects a flat portion spaced apart in parallel with the main body portion in the plate thickness direction, a lengthwise end portion of the main body portion, and an end portion of the flat portion. In order to do so, a rising portion rising in the plate thickness direction is provided, and the insertion hole is formed from an end portion of the flat portion to an end portion of the rising portion so as to include a connection boundary between the flat portion and the rising portion. It is possible to adopt a configuration in which the dimension in the plate thickness direction of the opening formed at the end of the rising portion is the same as or substantially the same as the thickness of the waist belt. ..

  In the wearing tool having the above configuration, since the insertion hole is formed between the flat portion and the rising portion, the waist belt is utilized by utilizing the opening formed in the flat portion and the opening formed in the rising portion. It can be easily inserted into and removed from the insertion hole. Further, of the insertion holes, since the dimension of the opening formed in the rising portion in the plate thickness direction is the same as or substantially the same as the thickness of the waist belt, the hook of the trunk is erroneously inserted through the insertion hole. Can be prevented from being locked.

  According to the wearing tool that can be worn by the wearing tool including the torso and the waist belt according to the present invention, it is possible to prevent the hook of the torso from being accidentally locked.

  A mounting tool that can be mounted on a mounting tool including a torso and a waist belt according to an embodiment of the present invention will be described. First, a safety belt as a mounting tool to which the mounting tool of the present invention is mounted will be described. As shown in FIG. 6, the safety belt 5 includes a waist belt 50 having a length that can be worn around a person's waist, and a waist belt 50 in which the waist belt 50 is inserted through a belt loop 50a. Also, a wide waist support 51, the waist belt 50 are inserted, and a pair of locking rings 52, 52 are arranged at a predetermined interval in the length direction of the waist belt 50, and the length of the waist belt 50 is adjusted. And a trunk 53 having a hook 55 that can be locked to the locking ring 52 at an end thereof. In the region between the pair of locking rings 52, 52 of the waist belt 50, as shown in FIG. 7, a tool holder 6 for suspending a tool required for work on a column is provided. The tool holder 6 includes an annular hanging portion 60 that can be hung on the waist belt 50, and a tool holding portion 61 that is a bag body that is connected to the hanging portion 60. The suspending portion 60 is formed in an annular shape so that the waist belt 50 can be surrounded in the width direction thereof, and the annular inner opening (insertion annular portion) is inserted through the waist belt 50. It is mouth 600.

  The mounting tool according to the present invention is configured to be mountable on a mounting tool such as the safety belt 5 that is mounted around a waist of a human body. In this embodiment, as shown in FIG. 2, the wearing tool 1 is applied as a cover of a tool holder 6 attached to a waist belt 50 of a safety belt 5. As shown in FIGS. 1 and 2, in the cover 1 according to the present embodiment, a pair of insertion holes 111 through which the waist belt 50 can be inserted are formed so as to face each other while being separated in the insertion direction of the waist belt 50. The mounting body portion 1A includes a mounting body portion 1A, and the mounting body portion 1A includes a body portion 10 and a pair of mounting portions 11 and 11 extending from both ends of the body portion 10. In the present embodiment, in the cover 1, the pair of mounting portions 11 and 11 are raised to the back surface side of the main body 10 in the front-back direction (plate thickness direction) to form the recess 10a on the back surface side. The hanging portion 60 of the tool holder 6 suspended by the waist belt 50 is housed in the recess 10a and covered. In other words, the waist belt 50 to which the cover 1 is attached does not have the hook 55 of the trunk 53, except for the hook ring 52.

  The body portion 10 is formed in a rectangular flat plate shape having a predetermined constant dimension in the length direction and the width direction, is formed in substantially the same shape as the hanging portion 60 of the tool holder 6, and the surface of the hanging portion 60. Is located in. The main body 10 has substantially the same shape as the suspending portion 60 because, for example, if the main body 10 is smaller than or larger than the suspending portion 60, the suspending portion 60 protrudes from the main body 10. Alternatively, when the main body portion 10 protrudes from the hanging portion and the hook 55 of the rope 53 may be mistakenly locked to the protruding portion, the main body portion 10 having substantially the same shape as the hanging portion 60 is suspended. By arranging it on the hanging portion 60, the hanging portion 60 is covered by the body portion 10 without forming a protruding portion between the body portion 10 and the hanging portion 60, and the hook 55 of the body rope 53 is formed. It is possible to prevent the wrong locking. In short, the main body 10 may have any shape as long as the hook 55 of the trunk 53 cannot be locked between the main body 10 and the hanging portion 60.

  As shown in FIGS. 1A to 1C, the pair of attachment portions 11 and 11 are provided at both ends in the longitudinal direction of the main body portion 10 so as to cover the insertion opening 600 of the suspension portion 60. A rising portion 110 extending from the portion and a flat portion 112 extending from the end portion of the rising portion 110 along the length direction are provided.

  As shown in FIG. 1C, the rising portion 110 is raised from the longitudinal end of the main body portion 10 toward the back surface direction of the main body portion 10 in the thickness direction (front and back direction) of the main body portion 10. It is configured so as to be inclined outward in the longitudinal direction toward the back surface side. Specifically, in order that the corner portion (connecting portion) R1 formed by the main body portion 10 and the rising portion 110 does not become the locking portion of the hook 55 of the body rope 53, the back surface side of the main body portion 10 and the rising portion 110 is The angle formed is obtuse. Further, as shown in FIG. 1A, the rising portion 110 has the same width dimension as the width direction dimension H1 of the main body portion 10 at the end portion (one end portion) on the connection side with the main body portion 10, and the other end portion. It is configured such that the width direction dimension H2 becomes smaller toward the portion side (the end portion on the side connected to the flat portion 112 described later).

  As shown in FIG. 1C, the flat portion 112 is continuously provided in the lengthwise outward direction from the other end of the rising portion 110, and is directed to the back side in the front-back direction (plate thickness direction) with respect to the main body portion 10. The main body 10 and the main body 10 are spaced apart from each other by a predetermined distance, and the lengthwise direction is parallel to the widthwise direction. As shown in FIGS. 1A to 1C, the flat part 112 has a connection end (one end) connected to the other end of the rising part 110 connected to the other end of the rising part 110 to form a connection boundary. The connecting portion (corner portion) R2 is included, and the connecting angle between the flat portion 112 and the rising portion 110 (the angle on the back surface side of the connecting portion) is an obtuse angle. In this way, when the connection angle between the flat portion 112 and the rising portion 110 is an obtuse angle, when the worker wears the waist belt 50, the pressure on the waist portion X of the worker by the corner portion R2 can be alleviated ( (See FIG. 3).

  Further, as shown in FIG. 1A, the flat portion 112 has a width dimension H2 at one end that is substantially the same as the width dimension at the other end of the rising portion 110, and the width dimension H3 becomes closer to the other end. Is getting smaller. That is, the mounting portion 11 including the rising portion 110 and the flat portion 112 has a larger width dimension H1 at one end portion (the rising portion 110) connected to the main body portion 10 (substantially the same as the width dimension of the main body portion 10). ), The width dimension H3 is smaller toward the other end on the tip side. This makes it possible to reduce the portion protruding from the waist belt 50 in the state of being worn on the safety belt 5 as the wearing tool, and to effectively prevent the hook 55 of the torso 53 from being erroneously locked.

  As shown in FIGS. 1A to 1C, the attachment portion 11 is formed with an insertion hole 111 for inserting the waist belt 50. The insertion holes 111 are formed in the one mounting portion 11 and the other mounting portion 11, and are formed at substantially the same position in the thickness direction (front and back directions). Therefore, the pair of insertion holes 111, 111 are arranged to face each other in the length direction (the insertion direction in which the waist belt 50 is inserted). The insertion hole 111 is formed in the rising portion 110, and in the present embodiment, is formed between the rising portion 110 and the flat portion 112. Therefore, the insertion hole 111 is formed by allowing the opening 111a formed at the other end of the rising portion 110 and the opening 111b formed at one end of the flat portion 112 to communicate with each other. Therefore, the insertion hole 111 of the present embodiment is opened in the length direction at the opening 111a of the rising portion 110, and is opened in the thickness direction (front and back direction) by the opening portion 111b of the flat portion 112.

  As shown in FIGS. 1A to 1C, the inner peripheral surface of the insertion hole 111 has a back-side inner peripheral surface (a surface facing the back surface) 111c as an opening-shaped surface in the rising portion 110. In addition, it is a closed surface including an inward inner peripheral surface (a surface facing inward in the length direction) 111d as an opening forming surface in the flat portion 112. The insertion hole 111 has a dimension (opening dimension) L in the thickness direction (front and back directions) that is the same as or substantially the same as the thickness of the waist belt 50. As shown in FIGS. 1B and 1C, this dimension L is the thickness dimension of the opening that can be seen when the cover 1 as a mounting tool is viewed from the side in the length direction. Specifically, the dimension L in the thickness direction of the opening formed in the rising portion 110, which is the dimension in the thickness direction of the insertion hole 111, is the same as or substantially the same as the thickness of the waist belt 50. More specifically, the dimension L of the insertion hole 111 in the thickness direction is the dimension between the back-side inner peripheral surface 111c defining the insertion hole 111 and the surface of the flat portion 112.

  Next, a method of using the cover 1 according to this embodiment will be described. In the present embodiment, the pillars using the safety belt 5 are electric poles. A plurality of electric devices are arranged on the electric pole, and a plurality of scaffolding bolts for raising and lowering an operator are provided in a predetermined direction in the height direction of the electric pole so that inspection work for each electric device can be performed on the electric pole. It is provided so as to project radially outward at intervals.

  First, the worker mounts the tool holder 6 and the cover 1 on the waist belt 50 as shown in FIG. Specifically, the worker inserts the waist belt 50 into the insertion hole 111 of the one mounting portion 11 of the cover 1, and then inserts the waist belt 50 into the insertion opening 600 of the hanging portion 60 of the tool holder 6. .. Next, the worker inserts the waist belt 50 into the insertion hole 111 of the other mounting portion 11 of the cover 1. As a result, as shown in FIG. 3, the cover 1, the suspending portion 60, and the waist belt 50 are integrated in a state where the main body portion 10 of the cover 1 is superposed on the surface side of the suspending portion 60, and the suspending portion is integrated. The insertion opening 600 of 60 is covered by the pair of mounting portions 11, 11. At this time, since the angle of the corner R2 between the flat portion 112 and the rising portion 110 is an obtuse angle, the pressing of the worker's waist X by the corner R2 is alleviated.

  In this state, the main body portion 10 of the cover 1 and the pair of attachment portions 11, 11 cover the front surface and both side surfaces of the hanging portion 60 from the back surface side of the waist belt 50, so the hanging portion 60 and the main body portion of the cover 1 are covered. The hook 55 of the trunk 53 is prevented from being accidentally locked between the hanging portion 60 and the hanging portion 60 and the pair of mounting portions 11, 11.

  Next, the worker winds and wears the waist belt 50 around the waist. At the time of mounting, the hook 55 on one side of the trunk 53 is locked to the one locking ring 52, and the hook 55 on the other side of the trunk 53 is locked to the other locking ring 52.

  Next, the worker stands at a position facing the utility pole, removes the hook 55 on one side of the torso 53 from the locking ring 52, winds the hook around the utility pole, and locks the locking ring 52 again.

  At this time, since the dimension L of the insertion hole 111 in the thickness direction is the same as or substantially the same as the thickness dimension of the waist belt 50, it is possible to prevent the hook 55 from accidentally entering and locking the insertion hole 111. .. Moreover, since the angle of the connecting portion (corner) R1 between the main body portion 10 and the rising portion 110 is an obtuse angle, it is possible to prevent the hook 55 from being accidentally locked to the rising portion 110. Furthermore, since the width dimension H2 of the attachment portion 11 is smaller toward the tip end side than the connection end portion with the main body portion 10, it is possible to suppress the attachment portion 11 from excessively protruding in the width direction with respect to the waist belt 50. At this point, the hook 55 is prevented from being accidentally locked.

  Next, the worker adjusts the length of the rope 53 with the length adjuster 54 so as to maintain an appropriate working posture. That is, a working space is secured between the telephone pole and the worker. Next, the worker raises the utility pole to a desired height while using the scaffolding bolt while turning one side of the body rope 53 around the utility pole.

  Next, the operator places one foot on one scaffold bolt and the other foot on the other scaffold bolt. In this state, the worker again adjusts the length of the torso 53 with the length adjuster 54 and deposits his or her weight on the waist rest 51. This allows the worker to take a stable work posture with respect to the utility pole.

  As described above, the cover according to this embodiment can reliably prevent the hook 55 of the trunk 53 from being erroneously locked.

  In addition, although the case where the wearing tool of the present invention is implemented as the cover 1 of the tool holder 6 has been described in the present embodiment, for example, the shoulder belt to be worn on the shoulder of the worker and the waist of the worker can be wrapped around the waist. It is also possible to implement it as a connecting tool for connecting the shoulder belt and the waist belt to the full harness type safety belt to be worn. In this case, for example, as shown in FIGS. 4A and 4B, the connector 4 has a main body portion 40 and a mounting portion 41, and the connection portion 420 of the shoulder belt 42 is connected to the main body portion 40. It has possible connections 400. Specifically, the connecting portion 400 of the main body portion 40 is a male connecting portion 401 that is provided so as to project from the end portion of the main body portion 40 on the upper side in the width direction. The connecting portion 420 of the shoulder belt 42 is a female connecting portion 421 connected to an end portion of the shoulder belt 42, and is a female connecting portion 421 configured so that the male connecting portion 401 can be inserted and connected. ..

  Alternatively, the mounting tool of the present invention can be implemented as a tool holder. For example, as the tool holder, a tool holding portion may be provided so as to hang from the lower end of the main body in the width direction.

  As described above, the wearing tool of the present invention is applicable as long as it is worn on the wearing tool by inserting the waist belt 50.

  It should be noted that the present invention is not limited to the above-described embodiments, but can be variously modified.

  In the above-described embodiment, the cover 1 of the present invention exemplifies the case where the mounting portion 11 includes the rising portion 110 and the flat portion 112. However, the mounting portion may be configured by only the rising portion. In this case, as shown in FIG. 5A, the main body 20 is overlapped with the hanging portion 60, and the pair of mounting portions 21 and 21 extending in the orthogonal direction from both ends of the main body 20 are provided. The cover 2 has a U-shape in plan view. Each attachment portion 21 is composed of only the rising portion 210, and an insertion hole 211 for the waist belt 50 is formed near the end portion of the rising portion 210 opposite to the main body portion 20. In short, when the wearing tool of the present invention is used as a cover, the shape of the cover is superposed on the surface of the hanging portion 60 of the tool holder 6 and can be connected to the waist belt 50. Any shape may be used as long as it can cover at least the insertion opening 600.

  Further, in the above-described embodiment, the cover 1 of the present invention exemplifies the case where the insertion hole 111 is formed from the rising portion 110 to the flat portion 112. However, as shown in FIG. 5B, the cover 3 may have the insertion hole 311 formed only in the rising portion 310. In the figure, reference numeral 31 is a mounting portion and 312 is a flat portion.
