Below, we will explain the belt attachment holder for carrying work equipment (hereinafter, simply referred to as the "holder") according to various embodiments of the present invention, with reference to the drawings. However, in the following explanation, the following definitions will be used:

"Top" and "bottom" are based on the view when the user wears the holder via a belt. Additionally, "front" refers to the direction in which the work equipment attachment part described below is provided, and refers to the side opposite the side that faces the user's body when the holder is worn by the user. Additionally, "rear" refers to the direction in which the belt attachment part described below is provided, and refers to the side that faces the user's body when the holder is worn by the user. Additionally, "left" and "right" are based on the view from the front (front), and refer to the circumferential direction of the body (around the torso or chest) when the holder is attached to a belt.

FIG. 1 shows a schematic front view of holder 1A according to a first embodiment of the present invention. FIG. 2 shows a schematic rear view of holder 1A.

Referring to FIG. 1, the holder 1A has a number of work tool attachment parts 2 on the front side to which work tools can be attached. Here, the work tools include, for example, tools (hammers, crowbars, ratchet wrenches, electric screwdrivers, tape measures, etc.), or bags and tool holders for storing the tools. The multiple work tool attachment parts 2 are spaced apart in the vertical direction as shown in FIG. 1.

The holder 1A is arranged vertically and has multiple bodies 10, each of which has a work tool attachment portion 2.

The main body 10 includes a base 11 and a front part 12. The front part 12 is attached to the front side of the base 11. In the holder 1A, the work tool attachment portion 2 is formed by a slot groove extending in the vertical direction. In the holder 1A, the slot groove is formed by the base 11 and the front part 12. The base 11 includes a work tool guide surface 13 extending in the vertical direction. In addition, in the holder 1A, the base 11 includes a guide side wall 14 arranged on the left side of the work tool guide surface 13. The guide side wall 14 protrudes forward from the work tool guide surface 13 and extends in the vertical direction along the left edge of the work tool guide surface 13. Furthermore, in the holder 1A, a left flange 14e protruding to the right is provided at the upper end (front end) of the guide side wall 14. The left flange 14e extends in the front-rear direction at a distance from the work tool guide surface 13. On the other hand, the front part 12 is a plate member. The front part 12 has a downwardly concave edge 12e when attached to the base 11 as viewed from the front as shown in FIG. 1. The edge 12e, together with the left flange 14e of the base 11, constitutes the left guide flange of the slot groove, and also constitutes the lower stopper flange and the right flange of the slot groove. That is, in the holder 1A, the slot groove, i.e., the work tool attachment part 2, is constituted by the work tool guide surface 13 of the base 11 and the guide side wall 14 having the left flange 14e, and the edge 12e of the front part 12. As a result, the work tool can be attached to the holder 1A by inserting a bracket provided on the work tool into the work tool attachment part 2 (slot groove) from the upper side to the lower side. The technology of attaching the work tool by inserting a bracket into the work tool attachment part 2 is described in Patent Document 4.

In addition, in the holder 1A, the main body 10 is provided with a stopper member 15 for removing the work tool. In the holder 1A, the stopper member 15 is a block material that constitutes the work tool mounting portion 2 (slot groove). The stopper member 15 engages the bracket of the work tool that is attached along the slot groove. This fixes the work tool in a positioned state on the work tool mounting portion 2. Meanwhile, in the holder 1A, the stopper member 15 can be slid diagonally downward to the right to release the engagement of the work tool with the bracket. By releasing the stopper member 15, the user can easily remove the work tool from the holder 1A simply by pulling the work tool upward.

Next, referring to FIG. 2, holder 1A has a belt attachment section 3 on the rear side to which a belt 100 can be attached. Here, belt 100 refers to a belt-shaped member for attachment to a user. Belt 100 is not limited to a horizontal belt that is wrapped around the waist of a user, but can also be a vertical belt that extends in a substantially vertical direction, such as the vertical belt portion of a harness-type safety belt. Because belt attachment section 3 is provided on the rear side, holder 1A can be attached to belt 100 with work tool attachment section 2 facing forward.

In the example of the holder 1A, the holder 1A has two main bodies 10, an upper main body 10A and a lower main body 10B. The upper main body 10A is the main body 10 arranged on the upper side. In the holder 1A, the belt attachment part 3 is provided on the upper main body 10A. In the holder 1A, the belt attachment part 3 has a belt holder 31 that holds the belt 100. The belt 100 can be attached to the upper main body 10A by passing it through the gap formed between the base 11 and the belt holder 31. In the holder 1A, the belt attachment part 3 has a rectangular belt frame 32. The belt frame 32 has two beam parts 32a spaced apart in the vertical direction. The upper and lower ends of the belt holder 31 are fixed between the base 11 and the beam parts 32a, respectively.

The lower body 10B is disposed directly below the upper body 10A. This allows the lower body 10B to be suspended from the belt 100 by attaching the holder 1A to the belt 100. In the holder 1A, the lower body 10B is provided with a safety rope attachment part 16. In the holder 1A, the safety rope attachment part 16 is made of a wire. By attaching a safety rope to the safety rope attachment part 16, the safety rope can be used as a lifeline. In the holder 1A, the lower body 10B does not have a belt attachment part 3. However, the lower body 10B may be provided with the belt attachment part 3.

The multiple bodies 10 are connected to each other so that they can swing in the front-to-rear direction (perpendicular to the paper in Figs. 1 and 2). In the holder 1A, the bodies 10 can be swung in the front-to-rear direction by the swinging mechanism 4.

The holder according to the present invention can include at least one rocking mechanism 4 between an upper body 10A arranged at the top of the multiple bodies 10 and a lower body 10B arranged directly below the upper body 10A, for rocking the upper body 10A and the lower body 10B in the front-to-rear direction. The rocking mechanism 4 allows the upper body 10A and the lower body 10B to rock (rotate) in the front-to-rear direction relative to each other in the circumferential direction around the axis O1.

The holder 1A is provided with multiple rocking mechanisms 4 between the upper body 10A and the lower body 10B. This allows the upper body 10A and the lower body 10B to be rocked back and forth in multiple stages in the vertical direction. Specifically, the holder 1A is provided with two rocking mechanisms 4. This allows the upper body 10A and the lower body 10B in the holder 1A to be rocked back and forth in two stages in the vertical direction.

In FIG. 3, the holder 1A is shown with some of the front parts 12 removed from the holder 1A. In FIG. 3, the front part 12 of the upper body 10A has been removed from the base 11. The front part 12 of the lower body 10B has also been removed from the base 11. Furthermore, the stopper member 15 of the lower body 10B has also been removed from the base 11. Reference numeral 15s denotes a spring that biases the stopper member 15 in an upward and leftward direction. As a result, when the stopper member 15 is pressed down in a downward and rightward direction and the downward force is released, the biasing force (restoring force) of the spring 15s allows the stopper member 15 to return to its initial position in the upward and leftward direction. As shown in FIG. 3, the safety rope attachment portion 16 is screwed to the base 11 by a fastening element T.

FIG. 3 shows a shaft 41 and an intermediate member 43, which will be described later. Also, FIG. 4 shows a schematic representation of a portion that constitutes a part of the oscillating mechanism 4 provided in the holder 1A. FIG. 4 shows a hole 42, which will be described later. Furthermore, FIG. 5 shows a schematic representation of an intermediate member (block material) 43, which constitutes a part of the oscillating mechanism 4 provided in the holder 1A.

In holder 1A, the rocking mechanism 4 is composed of a shaft 41 and a hole 42 through which the shaft 41 passes. The rocking mechanism 4 rocks the upper body 10A and the lower body 10B in the front-rear direction by rotating the shaft 41 and the hole 42 relative to each other. Furthermore, in holder 1A, the rocking mechanism 4 includes an intermediate member 43 that includes the shaft 41 or the hole 42.

Referring to FIG. 3, in holder 1A, shaft 41 is formed by a rivet. Holder 1A has two shafts 41. In addition, holder 1A has a spacer 44, which will be described later. Spacer 44 is a cylindrical member through which shaft 41 passes.

Next, referring to FIG. 4, the upper body 10A has a hole 42. The hole 42 of the upper body 10A is configured as a through hole extending in the left-right direction. In the holder 1A, the upper body 10A has two downward protrusions 17. In the upper body 10A, the two downward protrusions 17 are integrally formed with the front part 12. Each of the two downward protrusions 17 extends downward from the front part 12. In the holder 1A, the two downward protrusions 17 are spaced apart in the left-right direction. In the holder 1A, a hole 42 is formed in each of the two downward protrusions 17.

The lower body 10B also has a hole 42. The hole 42 in the lower body 10B is also configured as a through hole extending in the left-right direction. In the holder 1A, the lower body 10B has one upward protrusion 18. In the holder 1A, the upward protrusion 18 is integral with the base 11. The upward protrusion 18 extends upward from the base 11. In the holder 1A, the hole 42 is formed in the upward protrusion 18.

Furthermore, referring to FIG. 5, the intermediate member 43 also has a hole 42. The hole 42 of the intermediate member 43 is also configured as a through hole. In the holder 1A, the intermediate member 43 is a block material formed by injection molding, casting, or the like. In the holder 1A, the intermediate member 43 has two holes 42. The two holes 42 are provided in an upper portion (one of the two extension direction ends of the intermediate member 43) and a lower portion (the other of the two extension direction ends of the intermediate member 43) of the intermediate member 43. The holder 1A has two intermediate members 43.

1, for example, the upper portions of the two intermediate members 43 are arranged on the left-right inner side of the two downward protrusions 17 of the upper body 10A. This allows one of the two shafts 41 to pass through the upper portions of the two intermediate members 43 and the two downward protrusions 17 of the upper body 10A. Meanwhile, the lower portions of the two intermediate members 43 are arranged on the left-right outer side of the upward protrusions 18 of the lower body 10B. This allows the other of the two shafts 41 to pass through the lower portions of the two intermediate members 43 and one upward protrusion 18 of the lower body 10B. In other words, in the holder 1A, the upper body 10A and the lower body 10B are connected by two swinging mechanisms 4 formed by the shafts 41 and holes 42. This allows the holder 1A to be swung forward and backward in two stages in the vertical direction by rotating the main body 10 relative to the shaft 41, or by rotating the intermediate member 43 relative to the shaft 41, or by both.

In the holder 1A, the multiple work tool attachment sections 2 are spaced apart in the vertical direction. This allows the holder 1A to attach multiple work tools while minimizing the space that the work tools occupy in the circumferential direction of the belt 100. Specifically, the user can attach and carry two or more work tools to one belt 100 using the belt width occupied by one holder 1A.

In addition, the holder 1A has a plurality of main bodies 10 arranged in the vertical direction, and the plurality of main bodies 10 are connected to each other so that they can swing. As a result, even if a plurality of work tools are hung at local positions on the belt 100 in the circumferential direction of the belt 100, the holder 1A can prevent the work tools from getting caught on the user's feet, etc., and is unlikely to interfere with the user's work. Therefore, the holder 1A can ensure the user's workability while carrying a plurality of work tools while reducing the space occupied by the belt 100. Specifically, in the holder 1A, the axis O1 is parallel to the direction in which the belt 100 passes. Therefore, the lower body 10B suspended from the upper body 10A can swing (rotate) in the front-rear direction, but cannot swing (rotate) in the left-right direction. In other words, the holder 1A does not twist the lower body 10B with respect to the upper body 10A. Due to such restrictions on the movable direction of the lower body 10B, it is easy to insert and remove work tools from the holder 1A. In addition, when the user carries the work equipment around with them, unnecessary movement (vibration and rattling) of the work equipment is reduced.

In addition, in the holder 1A, the rocking mechanism 4 is composed of a shaft 41 and a hole 42 through which the shaft 41 passes, and the upper body 10A and the lower body 10B are rocked in the front-to-rear direction by rotating the shaft 41 and the hole 42 relative to each other. In this case, the rocking of the upper body 10A and the lower body 10B can be achieved by simple means.

The holder 1A is also provided with a plurality of swinging mechanisms 4 between the upper body 10A and the lower body 10B, which swing the upper body 10A and the lower body 10B in the front-rear direction. In this case, the movable angle range of the lower body 10B relative to the upper body 10A can be secured wider. In other words, in this case, the degree of freedom of swing between the upper body 10A and the lower body 10B is increased. Specifically, when the work item attached to the lower body 10B comes into contact with the floor due to the user's movement such as crouching, the load (push-up force) from the floor is not directly applied to the belt attachment portion 3 (belt loop), and the plurality of swinging mechanisms 4 rotate upward to release the push-up force. In particular, by providing the holder 1A with a plurality of swinging mechanisms 4, the degree of freedom of swing between the upper body 10A and the lower body 10B can be secured to a range where the upper body 10A and the lower body 10B can be folded in half by, for example, facing each other in the front-rear direction via the intermediate member 43. This makes it easier for the user to work. As a specific example, the lower body 10B can be moved upward while maintaining a long work item such as a tool holder vertically. On the other hand, when the upper body 10A and the lower body 10B are directly connected, the force applied from the bottom to the top of the holder is difficult to release. Furthermore, according to the holder 1A, by providing a plurality of swing mechanisms 4, when the work item is pulled out from the lower body 10B, the lower body 10B is lifted vertically in the up-down direction parallel to the upper body 10A without the holder 1A swinging (swinging) with the belt 100 as the base point. Therefore, the holder 1A is easy to use when inserting and removing the work item. On the other hand, when the upper body 10A and the lower body 10B are directly connected, the long work item such as a tool holder is easily rotated so as to bounce up with the belt 100 as the base point. In addition, when holder 1A is not in use, the upper body 10A and the lower body 10B can be folded in half, reducing storage space.

In particular, in the holder 1A, the rocking mechanism 4 includes an intermediate member 43 with a hole 42. In this case, the degree of freedom of rocking between the upper body 10A and the lower body 10B can be increased with a simple configuration. The intermediate member 43 may include a protrusion instead of the hole 42. In this case, the protrusion is rotatably supported by the hole 42 formed in the upper body 10A and the lower body 10B. In this case, the shaft 41 as a separate member can be omitted. Also, according to the present invention, the hole 42 can be a closed hole with the depth side of the hole 42 closed, rather than a through hole. In this case, the shaft 41 can be a protrusion protruding from the main body 10 or the intermediate member 43, as described above.

Furthermore, in the holder 1A, the intermediate member 43 is made of a block material. In this case, the strength of the intermediate member 43 can be increased by simple means. Therefore, in this case, for example, the holder 1A can be made of a resin such as engineering plastic. However, the holder 1A can also be made of a metal such as an aluminum alloy.

In addition, in the holder 1A, a spacer 44 is disposed between the upper portions of the two intermediate members 43. This allows the upper portions of the two intermediate members 43 to be positioned appropriately in the left-right direction. Therefore, with the holder 1A, rattling in the left-right direction that may occur between the two intermediate members 43 is suppressed.

FIG. 6 shows a schematic left side view of holder 1A. As shown in FIG. 6, lower body 10B is located further forward than upper body 10A. The upward protrusion 18 of lower body 10B extends diagonally upward and rearward. This allows lower body 10B to be positioned farther away from the user when holder 1A is attached to a belt. Therefore, holder 1A makes it possible to prevent lower body 10B from getting in the way of the user's feet when holder 1A is suspended from belt 100.

7A shows another example of the intermediate member (block material) 43 constituting a part of the rocking mechanism 4, together with the upper body 10A and the lower body 10B. The intermediate member 43 in FIG. 7A is obtained by connecting two intermediate members 43 in FIG. 5 in the left-right direction. The intermediate member 43 has two upward projections 43a extending upward and two downward projections 43b extending downward. The two upward projections 43a and the two downward projections 43b are connected by a connecting portion 43c extending in the left-right direction. In this example, the two upward projections 43a and the two downward projections 43b are arranged at positions shifted in the left-right direction. In this case, as shown in FIG. 7A, the downward projection 17 of the upper body 10A and the upward projection 18 of the lower body 10B can be configured to be shifted in the left-right direction. FIG. 7B is a perspective view showing the intermediate member (block material) 43 in FIG. 7A in a schematic manner. In this example, the holes 42 are provided on the side of the upward protrusion 43a and the side of the downward protrusion 43b.

In FIG. 8, yet another example of an intermediate member (block material) is shown diagrammatically together with an upper body 10A and a lower body 10B. The intermediate member 43 in FIG. 8 has one upward protrusion 43a and two downward protrusions 43b. In this example, by using a spacer 44, the downward protrusion 17 of the upper body 10A and the upward protrusion 18 of the lower body 10B can be configured to be offset in the left-right direction, as shown in FIG. 8.

FIG. 9 shows a schematic example of an upper body 10A and a lower body 10B connected by multiple intermediate members (blocks) 43.

A plurality of intermediate members 43 can be arranged between the upper body 10A and the lower body 10B. In the example of FIG. 9, the upper body 10A and the lower body 10B are connected by using two intermediate members 43. In this case, the upward protrusion 43a of the lower intermediate member 43 of the two intermediate members 43 is arranged inside in the left-right direction of the two downward protrusions 43b of the upper intermediate member 43 of the two intermediate members 43. This allows the third shaft 41 to pass through one upward protrusion 43a of the lower intermediate member 43 and two downward protrusions 43b of the upper intermediate member 43. This allows the holder in FIG. 9 to be swung in the front-rear direction in the up-down direction by the upper intermediate member 43 rotating relative to the shaft 41, or by the lower intermediate member 43 rotating relative to the shaft 41, or by both. That is, in the holder of FIG. 9, in addition to the rocking mechanism 4 between the upper body 10A and the upper intermediate member 43, and the rocking mechanism 4 between the lower body 10B and the lower intermediate member 43, another rocking mechanism 4 is configured between the two intermediate members 43. That is, in the case of the holder of FIG. 9, the holder has three rocking mechanisms 4. Therefore, in the case of the holder of FIG. 9, the upper body 10A and the lower body 10B can be rocked in the front-back direction in three stages in the up-down direction. According to the holder of the present invention, by increasing or decreasing the number of rocking mechanisms 4 as in the holder of FIG. 9, the holder can be changed to the optimal position for each user, and as a result, the user's workability can be improved.

In this example, a spacer 44 can be placed between the downward protrusion 17 of the upper main body 10A and the upward protrusion 43a of the upper intermediate member 43. A spacer 44 can also be placed between the downward protrusion 43b of the upper intermediate member 43 and the upward protrusion 43a of the lower intermediate member 43. A spacer 44 can also be placed between the upward protrusion 18 of the lower main body 10B and the downward protrusion 43b of the lower intermediate member 43.

Furthermore, as shown in FIG. 1, for example, the holder 1A is provided with a safety rope attachment part 16 on the lower main body 10B, which is located at the lowest position among the multiple main bodies 10. In this case, the safety rope attachment part 16 can be swung (rotated) in the front-rear direction by the swinging mechanism 4. Therefore, with the holder 1A, even when the user bends forward with the holder 1A attached to the front of his/her body via the belt 100, the safety rope attachment part 16, which is located below the belt 100, is unlikely to come into contact with the body and will not hinder the user's movement.

FIG. 10 shows a schematic example of an upper body 10A and a lower body 10B connected by a number of other intermediate members (block materials) 43. In the example of FIG. 10, the upper body 10A and the lower body 10B are also connected by using two intermediate members 43. In this case, the upper body 10A and the lower body 10B can be swung forward and backward in three stages in the vertical direction.

In this example, the intermediate member 43 has two upward protrusions 43a and one downward protrusion 43b. In addition, in this example, the two upward protrusions 43a extend from the downward protrusion 43b.

On the other hand, the upper body 10A has one downward protrusion 17. The two upward protrusions 43a of the upper intermediate member 43 of the two intermediate members 43 are arranged on the left-right outer side of the downward protrusion 17 of the upper body 10A. This allows one of the three shafts 41 to pass through the one downward protrusion 17 of the upper body 10A and the two upward protrusions 43a of the upper intermediate member 43. In addition, the one downward protrusion 43b of the upper intermediate member 43 of the two intermediate members 43 is arranged on the left-right inner side of the two upward protrusions 43a of the lower intermediate member 43. This allows the other one of the three shafts 41 to pass through the one downward protrusion 43b of the upper intermediate member 43 and the two upward protrusions 43a of the lower intermediate member 43. Furthermore, the lower body 10B has two upward protrusions 18. Of the two intermediate members 43, one downward protrusion 43b of the lower intermediate member 43 is positioned inside in the left-right direction of the two upward protrusions 18 of the lower main body 10B. This allows the remaining one of the three shafts 41 to pass through one downward protrusion 43b of the lower intermediate member 43 and the two upward protrusions 18 of the lower main body 10B.

With the above three configurations, the holder in FIG. 10 also has a rocking mechanism 4 between the upper main body 10A and the upper intermediate member 43, and a rocking mechanism 4 between the lower main body 10B and the lower intermediate member 43, and further has another rocking mechanism 4 between the two intermediate members 43. In other words, the holder in FIG. 10 also has three rocking mechanisms 4, just like the holder in FIG. 9. Therefore, in the holder in FIG. 10 as well, the upper main body 10A and the lower main body 10B can be rocked in the front-back direction in three stages in the up-down direction.

In the holder of FIG. 10, the upper of the two intermediate members 43 has two upward protrusions 43a curved inwardly in the left-right direction so that they approach each other. Also, in the holder of FIG. 10, the lower of the two intermediate members 43 has two upward protrusions 43a inclined inwardly in the left-right direction so that they approach each other.

FIG. 11 shows a schematic front view of holder 1B according to a second embodiment of the present invention. FIG. 12 shows a schematic rear view of holder 1B.

In holder 1B, the intermediate member 43 is made of plate material.

Referring to FIG. 11, the holder 1B also has two main bodies 10, an upper main body 10A and a lower main body 10B, which are spaced apart in the vertical direction. The holder 1B also has a work tool attachment portion 2 on the front side of each of the upper main body 10A and the lower main body 10B. In the holder 1B as well, the work tool attachment portion 2 is formed by a slot groove extending in the vertical direction.

As shown in FIG. 11, in holder 1B, the slot groove is also formed by a base 11 and a front part 12. The base 11 has a work tool guide surface 13 extending in the vertical direction. On the other hand, the front part 12 is a plate member. The front part 12 also has a downward concave edge 12e formed when attached to the base 11 in a front view as shown in FIG. 11. In holder 1B, the front part 12 has a guide side wall 14 arranged on the left side of the work tool guide surface 13. The left flange 14e provided at the upper end (front end) of the guide side wall 14 constitutes the edge 12e of the front part 12. As in holder 1A, the edge 12e of the front part 12, together with the left flange (14e), constitutes the lower stopper flange of the slot groove and the right guide flange of the slot groove. That is, in holder 1B, the slot groove, i.e., the work tool attachment part 2, is formed by the work tool guide surface 13 of the base 11 and the front part 12. As a result, the work tool can be attached to holder 1B by inserting the bracket provided on the work tool from the top to the bottom of the work tool attachment part 2 (slot groove) in the same way as holder 1A.

Next, referring to FIG. 12, holder 1B also has a belt attachment portion 3 on the rear side of upper body 10A. In holder 1B, belt holder 31 is an inverted U-shaped member. In holder 1B, belt holder 31 is attached to base 11 so as to be able to swing back and forth circumferentially around axis O2. In other words, in holder 1B, belt holder 31 can be opened and closed circumferentially around axis O2 relative to base 11. Opening due to swinging of belt holder 31 can be prevented by a detachable fastening element T. Fastening element T can be, for example, a threaded shaft that fixes base 11 and belt holder 31 together.

In FIG. 13, the holder 1B is shown with some components of the front part 12 removed from the holder 1B. In FIG. 13, the front part 12 of the upper body 10A has been removed from the base 11. In the holder 1B, the upper body 10A has two downward projections 17. In the holder 1B, the two downward projections 17 are provided on the base 11. In the holder 1B, the front part 12 of the lower body 10B has also been removed from the base 11. In the holder 1B, the lower body 10B has one upward projection 18. In the holder 1B, the one upward projection 18 is provided on the base 11. Furthermore, the stopper member 15 of the lower body 10B has also been removed from the base 11. Reference numeral 15s denotes a spring that biases the stopper member 15 diagonally upward to the left.

Holder 1B also includes an intermediate member 43 with a shaft 41 or a hole 42. FIG. 12 shows the shaft 41 and intermediate member 43. Referring to FIG. 12, in holder 1B, shaft 41 is formed by a bolt. Shaft 41 is connected to main body 10 and intermediate member 43 by a nut 41n.

FIG. 14 also shows a schematic view of a portion that constitutes a part of the rocking mechanism 4 provided in the holder 1B. Referring to FIG. 14, the upper body 10A has a hole 42. The hole 42 in the upper body 10A is formed as a through hole. In the holder 1B, the upper body 10A has two downward protrusions 17. In the holder 1B, a hole 42 is formed in each of the two downward protrusions 17. The lower body 10B also has a hole 42. The hole 42 in the lower body 10B is also formed as a through hole. In the holder 1B, the lower body 10B has one upward protrusion 18. In the holder 1B, the hole 42 is formed in the upward protrusion 18.

15, the intermediate member 43 also has a hole 42. The hole 42 of the intermediate member 43 is also formed by a through hole. In the holder 1B, the intermediate member 43 is a plate material. In the holder 1B, the intermediate member 43 has two upward protrusions 43a extending upward and two downward protrusions 43b extending downward. The two upward protrusions 43a and the two downward protrusions 43b are connected by a connecting portion 43c extending in the left-right direction. In the holder 1B, the two upward protrusions 43a and the connecting portion 43c form a flat plate-like portion. Furthermore, in the holder 1B, the two upward protrusions 43a each have an upper bent portion 43d bent rearward from the upward protrusions 43a. Also, in the holder 1B, the connecting portion 43c has a lower bent portion 43e bent rearward from a part of the connecting portion 43c. Furthermore, the two downward projections 43b are bent downward from both the left and right sides of the lower bent portion 43e. In the holder 1B, the holes 42 are formed in the two upper bent portions 43d and the two downward projections 43b.

11, the two upper bent portions 43d of the intermediate member 43 are arranged on the left-right outer side of the two downward protrusions 17 of the upper body 10A. This allows one of the two shafts 41 to pass through the two downward protrusions 17 of the upper body 10A and the two upper bent portions 43d of the intermediate member 43, just like the holder 1A. On the other hand, the one upward protrusion 18 of the lower body 10B is arranged on the left-right inner side of the two downward protrusions 43b of the intermediate member 43. This allows the other of the two shafts 41 to pass through the one upward protrusion 18 of the lower body 10B and the two downward protrusions 43b of the intermediate member 43, just like the holder 1A. In other words, in the holder 1B, the upper body 10A and the lower body 10B are connected by two swinging mechanisms 4, just like the holder 1A. This allows the upper body 10A and the lower body 10B of the holder 1B to be swung forward and backward in two stages in the vertical direction.

In holder 1B, intermediate member 43 is made of plate material. In this case, intermediate member 43 can be easily manufactured by bending processing such as press working. As a result, in holder 1B, intermediate member 43 can be formed from a metal such as an aluminum alloy. However, in holder 1B, intermediate member 43 can be formed from a resin such as engineering plastic. In other words, intermediate member 43 can be formed by injection molding or casting.

FIG. 16 shows a schematic left side view of holder 1B. As shown in FIG. 16, lower body 10B is located forward of upper body 10A, similar to holder 1A. The upward protrusion 18 of lower body 10B extends diagonally upward and rearward, similar to holder 1A. As a result, in holder 1B as well, lower body 10B is positioned farther away from the user when holder 1B is attached to belt 100. Therefore, similar to holder 1A, holder 1B also makes it possible to prevent lower body 10B from getting in the way of the user's feet when holder 1B is suspended from belt 100.

FIG. 17A shows a schematic diagram of another example of an intermediate member (plate material) 43. In this example, holes 42 are formed in each of two upward protrusions 43a and two downward protrusions 43b of the intermediate member 43. The upward protrusions 43a and the downward protrusions 43b are formed by bent portions that are bent in the front-rear direction from the connecting portion 43c. FIG. 17B shows a schematic diagram of one example of a manufacturing method for the intermediate member (plate material) 43 of FIG. 17A. The intermediate member 43 of FIG. 17A can be formed by bending a single plate material, as shown by the arrow in FIG. 17B.

18 shows another example of the intermediate member (plate material) 43 together with the shaft 41. In this example, the intermediate member (plate material) 43 is formed by bending the flat side of the plate material inward in the left-right direction. In this example, two oscillating mechanisms 4 can be configured in the vertical direction. For example, the upper shaft 41 of the two shafts 41 is connected to the upper part of the intermediate member 43 in a state of being hung between the intermediate members 43. The upper shaft 41 can be configured as an oscillating mechanism 4 by penetrating one downward protrusion 17 provided on the upper main body 10A, for example, as shown in FIG. 10. On the other hand, the lower shaft 41 of the two shafts 41 passes through a hole 42 formed in the lower part of the intermediate member 43. The lower shaft 41 can be configured as another oscillating mechanism 4 by being fixed or held by two upward protrusions 18 provided on the lower main body 10B, for example, as shown in FIG. 10.

Furthermore, FIG. 19 shows a schematic example of an intermediate member (plate material) 43 that constitutes part of the oscillating mechanism 4, which is connected via a shaft 41. In this example, three oscillating mechanisms 4 can be formed by using two intermediate members 43.

20 shows another example in which multiple intermediate members (plate material) 43 are connected via shafts 41 together with the lower body 10B. In this example, three intermediate members 43 are used. The three intermediate members 43 are formed by bending the flat side of the plate material inward in the left-right direction, similar to the intermediate member 43 in FIG. 18. Furthermore, in this example, the uppermost intermediate member 43 of the three has two upper bent portions 43d bent upward inward in the left-right direction. In this example, the upper bent portion 43d is a flat portion perpendicular to the front-rear direction (in FIG. 20, the direction perpendicular to the paper surface). Furthermore, the upper bent portion 43d has a mounting hole A43 penetrating in the front-rear direction. In this case, as will be described with reference to FIG. 3, the intermediate members 43 can be connected by using the configuration of the base 11 of the body 10 of the holder 1A. In other words, the uppermost of the three intermediate members 43 can be screwed to the base 11 of the upper body 10a with the fastening element T by using the mounting hole A43.

21 shows another example in which multiple intermediate members (plates) 43 are connected via shafts 41 together with the lower body 10B. In this example, three intermediate members 43 are used. As in the intermediate member 43 in FIG. 17A, the three intermediate members 43 have an upward protrusion 43a extending upward from the connecting portion 43c. The upper bent portion 43d is formed by a bent portion bent from the upward protrusion 43a along the front-rear direction. The downward protrusion 43b is formed by a bent portion bent from the connecting portion 43c along the front-rear direction. However, the uppermost intermediate member 43 of the three intermediate members 43 has a mounting hole A43 formed in the upward protrusion 43a. In this example, the upward protrusion 43a is a flat portion perpendicular to the front-rear direction (in FIG. 20, the direction perpendicular to the paper surface). The mounting hole A43 penetrates the upward protrusion 43a in the front-rear direction. In this example, similar to the example of FIG. 20, the uppermost intermediate member 43 of the three intermediate members 43 can be screwed to the base 11 of the upper body 10a with a fastening element T by using the mounting hole A43. Also, in the example of FIG. 21, the shaft 41 of the middle intermediate member 43 of the three intermediate members 43 and the lowermost intermediate member 43 is configured with a pin. The hole 42 is configured with a closed hole that rotatably holds the shaft 41. Also, a spacer 44 is interposed between the lowermost intermediate member 43 and the lower body 10B.

FIG. 22 shows an example of a combination of an intermediate member (block material) 43 and an intermediate member (plate material) 43 together with the lower body 10B. In this example, two intermediate members 43 are used. The upper intermediate member 43 of the two intermediate members 43 is an intermediate member 43 made of plate material. The upper intermediate member 43 can be screwed to the base 11 of the upper body 10a with fastening elements T by using mounting holes A43. The lower intermediate member 43 of the two intermediate members 43 is an intermediate member 43 made of block material. The lower intermediate member (block material) 43 can be connected to the shaft 41 (not shown) by making the downward projection 43b of the upper intermediate member 43 into a bent portion bent along the front-rear direction.

FIG. 23 shows a schematic front view of holder 1C according to a third embodiment of the present invention. FIG. 24 shows a schematic rear view of holder 1C.

In holder 1C, the intermediate member 43 is made of plate material.

Referring to FIG. 23, the holder 1C also has two main bodies 10, an upper main body 10A and a lower main body 10B, which are spaced apart in the vertical direction. The holder 1C also has a work tool attachment part 2 on the front side of each of the upper main body 10A and the lower main body 10B. In the holder 1C, the work tool attachment part 2 is also configured by a slot groove extending in the vertical direction. As shown in FIG. 23, in the holder 1C, the slot groove is also configured by a base 11 and a front part 12. The basic configuration of the slot groove is the same as in the holder 1B. As a result, like other holders, the work tool can be attached to the holder 1B by inserting a bracket provided on the work tool into the work tool attachment part 2 (slot groove) from the top to the bottom.

Next, referring to FIG. 24, holder 1C also has a belt attachment portion 3 of the same configuration as holder 1B on the rear side of upper body 10A. In addition, holder 1C has a belt attachment portion 3 of the same configuration as holder 1B on the rear side of lower body 10B. In holder 1C, belt holder 31 can be opened and closed in the circumferential direction around axis O2 relative to base 11, similar to holder 1B. And, opening of belt holder 31 due to swinging can also be prevented by detachable fastening element T, similar to holder 1B.

In FIG. 25, the holder 1C is shown with some components of the front part 12 removed from the holder 1C. In FIG. 25, the front part 12 of the upper body 10A has been removed from the base 11. In the holder 1C, the upper body 10A has a safety rope attachment 16 that functions as a shaft. In the upper body 10A, the safety rope attachment 16 is provided on the base 11. In the holder 1C, the front part 12 of the lower body 10B has also been removed from the base 11. In the holder 1C, the lower body 10B also has a safety rope attachment 16. In the lower body 10B, the safety rope attachment 16 is also provided on the base 11. Furthermore, the stopper member 15 of the lower body 10B has also been removed from the base 11.

The holder 1C is provided with two rocking mechanisms 4 between the upper body 10A and the lower body 10B, which rock the upper body 10A and the lower body 10B in the front-to-rear direction. In the holder 1C, the upper of the two rocking mechanisms 4 is composed of a shaft (16) and a fold 46 suspended from the shaft (16). By rotating the shaft (16) and the fold 46 relative to one another, the upper body 10A and the lower body 10B can be rocked in the front-to-rear direction.

In holder 1C, the shaft is safety rope attachment portion 16 provided on upper body 10A. In holder 1C, intermediate member 43 is composed of upper element 43A with fold 46 suspended from safety rope attachment portion 16, lower element 43B swingably connected to upper element 43A, and shaft 41.

In FIG. 26, the intermediate member (hanging) 43 of the holder 1C is shown in schematic form. In the holder 1C, the intermediate member 43 has an upper element 43A and a lower element 43B.

27 shows a schematic of the upper element 43A of the intermediate member 43. As shown in FIG. 27, the upper element 43A has a fold 46. In the holder 1C, the fold 46 has a shape in which a plate material is folded in the up-down direction. The fold 46 can be hooked to the safety rope mounting portion 16 of the upper body 10A to swing (rotate) in the circumferential direction around the safety rope mounting portion 16. That is, in the holder 1C, the upper swing mechanism 4 of the two swing mechanisms 4 is composed of the safety rope mounting portion 16 of the upper body 10A and the fold 46 of the upper element 43A. Furthermore, in the holder 1C, the upper element 43A has two folded side portions 47 on the left and right sides of the fold 46, which are folded along the front side or the rear side. In the holder 1C, one of the two folded side portions 47 is folded to the front side, and the other of the two folded side portions 47 is folded to the rear side. As a result, the two folded side portions 47 are positioned opposite each other in the left-right direction. A hole 42 is formed in each of the two folded side portions 47. In the holder 1C, the hole 42 penetrates the folded side portion 47 in the left-right direction.

28 shows a schematic of the lower element 43B of the intermediate member 43. In the holder 1C, the lower element 43B also has a shape formed by bending a plate material. The lower element 43B has a horizontal plate portion 48 for attachment to the belt attachment portion 3 of the lower main body 10B. The horizontal plate portion 48 extends in the left-right direction. The horizontal plate portion 48 can be sandwiched between the base 11 and the belt holder 31 of the lower main body 10B. This allows the lower element 43B to be attached to the belt attachment portion 3 of the lower main body 10B. In the holder 1C, the right side of the horizontal plate portion 48 is connected to an upward bypass portion 48a that forms a flat portion together with the horizontal plate portion 48. Furthermore, the upward bypass portion 48a is provided with an upward protrusion 43a that is bent rearward. On the other hand, in the holder 1C, the left side of the horizontal plate portion 48 forms a forward protrusion 48b that protrudes forward. Furthermore, the forward protrusion 48b also has an upward protrusion 43a that is bent rearward. Each of the two upward protrusions 43a has a hole 42 formed therein. In the holder 1C, the hole 42 penetrates the upward protrusion 43a in the left-right direction.

For example, referring to FIG. 23, the intermediate member 43 is constructed by connecting an upper element 43A and a lower element 43B via a shaft 41. That is, in the holder 1C, the lower of the two oscillating mechanisms 4 is constructed by the upper element 43A and the lower element 43B of the intermediate member 43 and the shaft 41 that connects them. This allows the lower oscillating mechanism 4 to be oscillated in the front-rear direction by the upper element 43A of the intermediate member 43 rotating relative to the shaft 41, or by the lower element 43B of the intermediate member 43 rotating relative to the shaft 41, or by both.

In addition, in the holder 1C, the upper swing mechanism 4 of the two swing mechanisms 4 is composed of the safety rope attachment part 16 of the upper body 10A and the fold 46 of the upper element 43A. As a result, the upper swing mechanism 4 can be swung in the front-rear direction by the upper body 10A rotating relative to the upper element 43A, or by the upper element 43A of the intermediate member 43 rotating relative to the upper body 10A, or by both. Therefore, the holder 1C can also be swung in the front-rear direction in two stages in the vertical direction, similar to the holders 1A and 1B. In particular, the fold 46 allows the upper body 10A and the lower body 10B to be swung in the front-rear direction without using the shaft 41. However, in the holder 1C, the safety rope attachment part 16 can also be a separate shaft 41 provided on the upper body 10A.

In addition, in the holder 1C, the intermediate member 43 is composed of an upper element 43A with a fold 46 that is suspended from the safety rope attachment portion 16, and a lower element 43B that is swingably connected to the upper element 43A. In this case, the holder 1C can be swung in two stages in the forward and backward directions in the up and down directions by simple means.

Furthermore, in holder 1C, upper element 43A and lower element 43B of intermediate member 43 are each made of plate material. In this case, upper element 43A and lower element 43B can be easily manufactured by bending processing such as press working. As a result, in holder 1C, upper element 43A and lower element 43B can be formed from metal such as aluminum alloy. However, in holder 1C, upper element 43A and lower element 43B can be formed from resin such as engineering plastic.

In particular, in the holder 1C, the lower element 43B has a horizontal plate portion 48. In the holder 1C, the intermediate member 43 can be attached to the lower main body 10B by sandwiching the horizontal plate portion 48 of the lower element 43B between the base 11 of the lower main body 10B and the belt retainer 31. In this case, when attaching the intermediate member 43 to the lower main body 10B, the existing belt attachment portion 3 can be used. In addition, the horizontal plate portion 48 can be provided with an anti-slip member. Examples of the anti-slip member include a porous resin body such as a sponge that can be attached to the horizontal plate portion 48, and an elastic tube such as a resin tube that penetrates the horizontal plate portion 48. Furthermore, in the holder 1C, the lower element 43B of the intermediate member 43 has an upward bypass portion 48a. In this case, the intermediate member 43 can be attached to the lower main body 10B without impairing the sliding function of the stopper member 15. Furthermore, in the holder 1C, the lower element 43B of the intermediate member 43 has a forward protrusion portion 48b. 23, in the holder 1C, the forward protrusion 48b comes into contact with the right side surface of the lower body 10B when the lower element 43B is attached to the lower body 10B. Therefore, in this case, the lower element 43B can be easily positioned in the left-right direction of the lower body 10B. However, the upward detour portion 48a and the forward protrusion 48b can be modified or deleted as appropriate to match the shape of the lower body 10B of the holder 1C.

FIG. 29 shows a schematic left side view of holder 1C. As shown in FIG. 29, the upward projection 43a of the lower element 43B of the intermediate member 43 is bent rearward. For this reason, in holder 1C, the lower body 10B is positioned further forward than the upper body 10A, similar to holder 1A and the like. As a result, in holder 1C as well, the lower body 10B is positioned farther away from the user when holder 1C is attached to the belt 100. Therefore, in holder 1C as well, when holder 1C is suspended from the belt 100, the lower body 10B is less likely to get in the way of the user's feet, similar to holder 1A and the like.

FIG. 30 shows a right side view, a rear view, and a left side view, which are schematic diagrams illustrating another example of the lower element 43B. In this example, the lower element 43B is composed of two parts 43B1 and 43B2. In this example, the two parts 43B1 and 43B2 are connected by a fastening element such as a rivet.

Figure 31 shows a schematic diagram of another example of the intermediate member (hanging) 43. In this example, the intermediate member (hanging) 43 is formed from a single plate material. In this way, the intermediate member (hanging) 43 can be easily formed by making cuts in a single plate material and bending each part along the cuts.

Figure 32 shows a schematic diagram of another example of the intermediate member (plate material) 43. In this example, the lower element 43B of the intermediate member 43 is connected to the downward projection 17 of the upper body 10A of the holder via a shaft 41 (not shown). In this case, there is one rocking mechanism 4 between the upper body 10A and the lower body 10B. In other words, in this example, the holder can be rocked in the front-rear direction at one location between the upper body 10A and the lower body 10B.

FIG. 33 shows a schematic rear view of a holder 1D according to a fourth embodiment of the present invention. FIG. 34 shows a schematic left side view of the holder 1D. In this example, instead of the swinging mechanism 4, the upper body 10A and the lower body 10B of the holder 1D are connected by a linear member 40. The linear member 40 is an endless member. In the holder 1D, the linear member 40 is connected through the belt attachment parts 3 of the upper body 10A and the lower body 10B. However, in this case, the linear member 40 can also be attached to the safety rope attachment part 6 of the upper body 10A. In either case, the upper and lower parts can be connected without adding any new attachment means.

The linear member 40 may be a string-like member having rigidity, such as a cord or rope. In this case, the end of the linear member 40 may be made into a ring shape, for example, by applying a heat welding process. A hook (such as a loop or shackle) may be provided at the end of the linear member 40 to connect the ends of the linear members 40 together. The end of the cord or rope may also be made into a loop shape and connected with a shackle or the like.

The linear member 40 may be a metallic member such as a wire. In this case, the ends of the wire may be welded together to form a rectangular or circular shape.

The linear member 40 may be a chain-like member. In this case, a hook (snap ring, shackle) or the like may be provided at the end of the chain to connect the ends together. Shackles may be provided at both ends of the chain, or the ends of the chain may be connected together with a single shackle.

The linear members 40 can also be connected with an elastic member. In this case, an elastic member such as rubber or a spring can be formed into a ring shape, and the ends of the elastic member can be connected together by welding or crimping.

In each of the above-mentioned holders, the work tool attachment portion 2 has a slot groove extending in the vertical direction. In this case, the work tool can be easily attached to each main body of the holder by inserting it from above. Also, when removing the work tool, it can be easily removed from each main body of the holder by pulling it up. FIG. 35 shows an example of a work tool 110 in a schematic manner. In FIG. 35, the work tool 110 is a tape measure. The work tool 110 is provided with a bracket 111 for inserting it into the work tool attachment portion 2. Note that items other than work tools can be attached to the work tool attachment portion 2. For example, instead of a work tool, a decorative plate can be attached. The decorative plate can be formed, for example, by a plate member equipped with a bracket 111. The decorative plate, for example, gives each of the above-mentioned holders a fashionable look or dust-proofness. Also, according to each of the above-mentioned holders, when worn by a user, the lower body 10B is positioned one step lower than a normal holder (existing holder). Therefore, even if a jacket is worn over each of the holders, the lower body 10B can be exposed from the bottom of the jacket. Therefore, with each of the holders described above, it is easy to take work items in and out of the lower body 10B. Furthermore, with each of the holders described above, the lower holder (10B) is positioned close to where the user's hands naturally hang down. Therefore, with each of the holders described above, it becomes easy to take tools in and out.

The decorative plate can also be used as a protective cover to protect the holder of the present invention.

In FIG. 36, a protective cover 50, which is an example of a protective cover that can be applied to the holder according to the present invention, is shown in a schematic perspective view from the rear side. The protective cover 50 can be used, for example, as a protective cover that protects the main body 10 of the holder 1A in FIG. 1.

As shown in FIG. 36, the protective cover 50 is provided with a plate member 51 that protects the front side of the main body 10 of the holder 1A. A bracket 111 is attached to the rear surface (back face) of the plate member 51. This allows the protective cover 50 to be removably attached to the main body 10 by inserting the bracket 111 into the work item attachment portion 2 of the holder 1A. Furthermore, the plate member 51 protects the front surface of the main body 10 by attaching the protective cover 50 to the main body 10 of the holder 1A. The outer shape of the plate member 51 is preferably shaped to cover the front surface of the main body 10. In this example, the plate member 51 has an outer shape that is roughly like a shuttlecock.

In addition, the protective cover 50 has a side plate 52 that is connected to the plate member 51. The side plate 52 extends from the plate member 51 toward the rear side. When the protective cover 50 is attached to the main body 10, the side plate 52 is positioned to cover at least one of the sides (top side, left and right side, and bottom side) of the main body 10 from the outside.

Referring to FIG. 36, for example, the upper plate 52a disposed on the upper side of the plate member 51 can cover the upper opening of the work tool attachment portion 2 (slot groove) provided on the main body 10 when the protective cover 50 is attached to the main body 10. This allows the upper plate 52a to prevent foreign matter such as dust and dirt from entering the inside of the work tool attachment portion 2 (slot groove). The entry of foreign matter may cause the holder 1A to break down or malfunction. For this reason, providing the upper plate 52a on the plate member 51, as in this example, is effective in preventing breakdowns or malfunctions.

Also, referring to FIG. 36, for example, left and right side plates 52b are arranged on at least one of the left and right sides of the plate member 51. The left and right side plates 52b can cover the side opening of the work tool attachment part 2 (slot groove) provided on the main body 10 when the protective cover 50 is attached to the main body 10. As a result, the left and right side plates 52b can also prevent foreign matter such as dust and dirt from entering the inside of the work tool attachment part 2 (slot groove) like the upper side plate 52a. The entry of foreign matter may cause failure or malfunction of the holder 1A. For this reason, as in this example, providing the left and right side plates 52b on the plate member 51 is effective in preventing failure or malfunction. In addition, the plate member 51 covering the front surface of the main body 10 can cover the stopper member 15 provided on the main body 10 from the front surface. In this example, the plate member 51 covers the front surface of the stopper member 15 to prevent the operation of the stopper member 15. This prevents erroneous operation, such as the user unintentionally pressing down the stopper member 15 on the main body 10, when the protective cover 50 is attached to the main body 10 of the holder 1A. Also, when the holder 1A is used without anything inserted into the work tool attachment portion 2, only the stopper member 15 is exposed, and there is a risk of the stopper member 15 being damaged, for example, if it is accidentally bumped or caught on something. For this reason, as in this example, providing the protective cover 50 on the plate member 51 when the protective cover 50 is attached to the main body 10 of the holder 1A is effective in preventing damage to the stopper member 15.

In this example, the lower end 111b of the bracket 111 has a tapered shape going downward. In this case, the bracket 111 can be easily inserted into the upper opening of the work tool attachment portion 2 (slot groove) provided on the main body 10. In addition, the left and right side plates 52b can also be positioned on the right side of the plate member 51 (in the embodiment of FIG. 1 etc., the left and right are defined based on the front) when the protective cover 50 is attached to the main body 10. This also prevents erroneous operation, such as the user unintentionally pressing down the stopper member 15 provided on the main body 10, when the protective cover 50 is attached to the main body 10 of the holder 1A.

Incidentally, in all holders according to this embodiment, such as holder 1A in FIG. 1, the stopper member 15 is located on the right side of the main body 10 (in the embodiment in FIG. 1 etc., left and right are defined based on the front). In such an embodiment, for example, as shown in FIG. 1, the work tool attachment portion 2 (slot groove) is located toward the left of the main body 10.

On the other hand, the stopper member 15 can also be placed on the left side to accommodate the dominant hand of the user (in the embodiment shown in FIG. 1 etc., left and right are defined based on the front). When the stopper member 15 is placed on the left side, the work tool attachment portion 2 (slot groove) is positioned toward the right of the main body 10.

Figures 37A to 37D show a schematic diagram of another example of a protective cover that can be used with the holder of the present invention, protective cover 60.

FIG. 37A shows another protective cover 60 from the front, and FIG. 37B shows the protective cover 60 from the back. Also, FIG. 37C shows the left side of the protective cover 60, and FIG. 37D shows the underside of the protective cover 60.

37A and 37B, in the protective cover 60, the bracket 111 is attached to the plate member 51 by the screw S. In this example, the plate member 51 has a plurality of through holes 51s arranged in one row in the vertical direction, and each row of through holes 51s has two rows in the horizontal direction. Specifically, two through holes 51s are arranged in one row in the vertical direction, and each row of through holes 51s has two rows in the horizontal direction. In this example, the bracket 111 has two screws S threaded through the through holes 51s in one row on the left side and screwed into the bracket 111. This allows the bracket 111 to be applied to a holder in which the stopper member 15 is arranged on the right side, as in the holder according to this embodiment. Also, in this example, the bracket 111 can have two screws S threaded through the through holes 51s in one row on the right side and screwed into the bracket 111. This allows the bracket 111 to be applied to a holder in which the stopper member 15 is arranged on the left side, as opposed to the holder according to this embodiment.

As described above, the position of the bracket 111 of the protective cover 60 can be changed by screwing. That is, the protective cover 60 can be applied to two types of holders with different positions of the stopper member 15. Therefore, the protective cover 60 has excellent cost benefits because one protective cover can be applied to two types of holders. Note that in this example, the left and right side plates 52b are omitted. However, even in this example, the left and right side plates 52b can be provided on at least one of the left and right sides of the plate member 51.

In this example, the lower end 111b of the bracket 111 also has a shape that tapers downward. Furthermore, in this example, the lower end 111b of the bracket 111 has a recess 111c that extends upward. In this case, the bracket 111 can be more easily inserted into the upper opening of the work tool attachment portion 2 (slot groove) provided on the main body 10.

The above is merely one embodiment of the present invention, and various modifications are possible within the scope of the claims.

When multiple intermediate members 43 are connected as described in FIG. 9 etc., by making one of the upper and lower sides of the intermediate members 43 wider in the left-right direction and making the other of the upper and lower sides of the intermediate members 43 narrower in the left-right direction, multiple intermediate members 43 can be arranged between the upper main body 10A and the lower main body 10B while suppressing the vertical dimension.

The upper body 10A and the lower body 10B can be connected by providing a hook on the top of the lower body 10B and hooking the hook onto the safety rope attachment part 16 of the upper body 10A. In this case, the hook can be replaced with a ring or carabiner. The upper body 10A and the lower body 10B can also be connected by embedding a hook in each of them.

Furthermore, a through hole can be provided in the upper part of the lower body 10B, and a key holder ring (carabiner) can be passed through the through hole and the safety rope attachment part 6 of the upper body 10A to connect it. In this case, the belt attachment part 3 of the upper body 10A and the lower body 10B can also be connected through the key holder ring.

A safety rope can also be attached to the shaft 41. Specifically, the safety rope attachment portion 16 can be swung back and forth relative to the main body 10. A loop or shackle for the safety rope can be attached to the shaft 41. The upper main body 10A and the lower main body 10B can also be directly connected by a shaft such as a pin or screw without using the intermediate member 43. The various configurations employed in each of the above-mentioned embodiments can be used in combination with each other.
