DETAILED DESCRIPTION OF THE INVENTION

[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An article holder attaching / detaching bracket and an article holder set, which are exemplary embodiments of the present invention, will be described below with reference to the drawings.

[0011] Figure 1 shows the item holder set 10 of the present invention, separated into an item holder attachment / detachment bracket 1 (hereinafter simply referred to as "bracket 1") and an item holder 2 (hereinafter simply referred to as "holder 2").

[0012] In the following description, the length direction refers to the direction in which the bracket is inserted and removed. In this embodiment, for convenience, the article holder set is used so that the length direction is the up-down direction. The width direction is the direction perpendicular to the length direction, and in this embodiment, it is the left-right direction when the article holder set is used. Furthermore, the thickness direction is the direction perpendicular to the length direction and the width direction, and in this embodiment, it is the front-to-back direction when the article holder set is used.

[0013] The article holder set 10 includes a bracket 1 and a holder 2. In FIG. 1, an arbitrary article M is fixed to the bracket 1. The bracket 1 can be attached to a mounting portion 21 provided on the holder 2 through an access opening A21 of the mounting portion 21. Conversely, the bracket 1 can be removed from the access opening A21 of the mounting portion 21. Therefore, the article M can be attached to and detached from the holder 2 via the bracket 1. Examples of the article M include tools used in construction work, electrical work, and other such work. Specific examples of the article M include rulers such as a convex (tape measure), a spirit level, a light (e.g., a flashlight), a tool holder, a rangefinder, and a finger ring. However, the article M may be any arbitrary article and is not limited to tools.

[0014] The holder 2 has an attachment portion 21 for attaching and detaching the bracket 1. In this embodiment, the attachment portion 21 has an access opening A21 that opens on the upper side of the holder 2. The attachment portion 21 has a slide surface F21 extending in the length direction, two guides 22 extending in the length direction and spaced apart in the width direction, and a reinforcing portion 23 that reinforces the two guides 22.

[0015] The guide 22 includes a guide wall (side wall) 22a extending longitudinally from the slide surface F21 and a guide hook (inward end) 22b extending widthwise inward from the front-side extending end of the guide wall 22a. In FIG. 1, the widthwise spacing between the two guides 22, i.e., the widthwise spacing between the two guide hooks 22b, is indicated by width W21. Specifically, width W21 is the widthwise dimension between the widthwise inner edges of the two guide hooks 22b. In this embodiment, width W21 is 20 mm. However, width W21, i.e., the widthwise dimension of the two guide hooks 22b, can be set appropriately. The slide surface F21 and the guide hooks 22b are spaced apart in the thickness direction (front-to-back direction). In FIG. 1, the thicknesswise spacing between the slide surface F21 and the guide hooks 22b is indicated by D21. Specifically, the distance D21 is the dimension between the slide surface F21 and the back surface F22b of the guide hook 22b in the thickness direction.

[0016] In this embodiment, the holder 2 includes a holder main body 2a and a holder cover 2b. In this embodiment, the holder cover 2b is a plate member fixed to the holder main body 2a by, for example, screws. In this embodiment, a recess that forms part of the mounting portion 21 is formed on the front side of the holder main body 2a. The holder cover 2b is fixed to the holder main body 2a so as to cover the recess that forms part of the mounting portion 21 formed in the holder main body 2a.

[0017] In this embodiment, the slide surface F21 is the bottom surface of the recess formed in the holder main body 2a. Furthermore, in this embodiment, the widthwise inner surface of the guide wall 22a is the side surface F22a of the recess. In contrast, in this embodiment, the guide hook 22b is formed by a notch formed in the holder cover 2b. In this embodiment, the thickness D22b of the guide hook 22b is the thickness of the holder cover 2b. In FIG. 1, the thickness of the holder cover 2b, i.e., the thickness of the guide hook 22b, is indicated by D22b. In this embodiment, the notch extends downward from the upper end of the holder cover 2b. Furthermore, in this embodiment, the reinforcing portion 23 is formed by the remaining portion of the holder cover 2b below the notch. In this embodiment, the back surfaces of the guide hook 22b and the reinforcing portion 23 are the back surfaces of the holder cover 2b.

[0018] The bracket 1 includes an insertion portion 11 and a shaft portion 12. The insertion portion 11 can be inserted into the attachment portion 21 from above and below because its movement in the width direction is restricted by two guide walls 22a provided on the holder 2, and its movement in the thickness direction is restricted by a slide surface F21 and two guide hooks 22b. The shaft portion 12 has an end portion on one thickness side that is connected to the insertion portion 11, and an end portion on the other thickness side that can be fixed to the article M, and is movable through a gap C21 formed between the two guide hooks 22b. In this embodiment, the bracket 1 can be fixed to the article M, for example, with a screw.

[0019] FIG. 2 shows a detachable article holder bracket 1A (hereinafter also referred to as "bracket 1A") according to a first embodiment of the present invention, viewed from the side of the insertion portion 11. In this embodiment, the central axis of the insertion portion 11 and the central axis of the shaft portion 12 are both coaxial with the central axis O of the bracket 1A. FIG. 3 is a left side view of FIG. 2. FIG. 4 is a plan view of FIG. 2. FIG. 5 is a rear view of FIG. 2.

[0020] As shown in FIG. 2, in this embodiment, the insertion portion 11 has a circular outer edge contour shape in a plan view. In this embodiment, the insertion portion 11 has an annular side surface F1. In this embodiment, the side surface F1 of the insertion portion 11 has a circular outline shape centered on the central axis (O) of the insertion portion 11 in a plan view, as shown in FIG. 2. Specifically, as shown in FIG. 2, the side surface F1 has a true circular outer edge contour shape with a diameter R1. As a result, in this embodiment, the insertion portion 11 has a circular outer edge contour shape as shown in FIG. 2.

[0021] In addition, as shown in Fig. 2, insertion portion 11 has an area larger than the area of ​​shank portion 12. In Fig. 2, the outer edge contour shape of shank portion 12 is shown by a dashed line. In this embodiment, as shown in Fig. 2, the area surrounded by the outer edge contour shape of insertion portion 11 shown by a solid line is larger than the area surrounded by the outer edge contour shape of shank portion 12 shown by a dashed line.

[0022] The diameter R1 of the outer edge contour shape of the insertion portion 11 is 18 mm or more and 25 mm or less, i.e., 18 mm ≦ R1 ≦ 25 mm, when the width W21 of the two guide hooks 22b provided on the holder 2 is 14 mm or more and 21 mm or less, i.e., 14 mm ≦ W21 ≦ 21 mm. More preferably, the diameter R1 is 18 mm or more and 24 mm or less, i.e., 18 mm ≦ R1 ≦ 24 mm. Furthermore, when the width W21 of the two guide hooks 22b provided on the holder 2 is 20 mm, the diameter R1 is greater than 20 mm and less than 24 mm, i.e., 20 mm ≦ R1 ≦ 25 mm. <R1≦24mmである。

[0023] As shown by the dashed line in FIG. 2, in this embodiment, the shank 12 also has a circular outer edge contour shape. In this embodiment, the shank 12 has an annular side surface F2. In this embodiment, the side surface F2 of the shank 12 has a circular outline shape centered on the central axis (O) of the shank 12 in a plan view, as shown in FIG. 2. Specifically, as shown in FIG. 2, the side surface F2 has a truly circular outer edge contour shape with a diameter R2. As a result, in this embodiment, the shank 12 has a circular outer edge contour shape, as shown in FIG. 2.

[0024] In addition, as shown in FIG. 2, the shank 12 is disposed relative to the insert portion 11 so that the outer edge of the insert portion 11 forms an endless flange 11a over the entire periphery.

[0025] Specifically, the outer edge contour shapes (side surfaces F1, F2) of the insertion portion 11 and the shank 12 are similar to each other. Furthermore, in this embodiment, the central axis of the insertion portion 11 and the central axis of the shank 12 are the same central axis O. As a result, the flange 11a protrudes outward from the shank 12 by an equal width (Δ11) around the entire circumference of the central axis O.

[0026] In this embodiment, the diameter R2 of the outer edge contour of the shaft portion 12 may be a dimension that allows the width W21 of the two guide hooks 22b provided on the holder 2 to pass through. For example, when the width W21 of the two guide hooks 22b provided on the holder 2 is 14 mm or more and 21 mm or less, i.e., 14 mm≦W21≦21 mm, the diameter R2 is 14 mm or more and 21 mm or less, i.e., 14 mm≦R2≦21 mm. More preferably, when the width W21 of the two guide hooks 22b provided on the holder 2 is 20 mm or less, the diameter R2 is 20 mm or less, i.e., R2≦20 mm. Furthermore, when the width W21 of the two guide hooks 22b provided on the holder 2 is 20 mm, the diameter R2 is preferably less than 20 mm, i.e., R2<20 mm.

[0027] The bracket 1 has a circular side surface F1 (outer edge contour shape) of the insertion portion 11, so that when attached to the holder 2, the item M can be carried or stored while being rotatable relative to the holder 2. Therefore, even if a load is unexpectedly applied to the item M, such as a tool, with the bracket 1, the load can be released by rotation via the bracket 1. Furthermore, the circular side surface F1 of the insertion portion 11 can prevent the holder main body 2a from contacting the guide wall 22a unevenly, which can occur when a corner is provided on the side surface F1 of the insertion portion 11. This improves the durability of the bracket 1, and therefore the holder main body 2a and the set 10. Furthermore, the circular side surface F1 of the insertion portion 11 with the bracket 1 prevents the holder main body 2a from contacting the guide wall 22a unevenly, making it easy to attach and detach the bracket 1 and, therefore, the item M.

[0028] Furthermore, with bracket 1, by setting diameter R1 of insertion portion 11 to 18 mm≦R1≦25 mm, it is possible to provide bracket 1 that has excellent tensile strength and a comfortable feel when attaching and detaching to holder 2, and article holder set 10 that includes bracket 1 and holder 2. Furthermore, if R1 is set to 20 mm≦R1≦24 mm, there is an excellent improvement in tensile strength when bracket 1 is attached to holder 2 and pulled from holder 2.

[0029] Therefore, according to this embodiment, it is possible to provide a bracket 1 that has excellent tensile strength and is easy to use when attaching and detaching from the holder 2, and a set 10 that includes the bracket 1 and the holder 2.

[0030] In FIG. 2, symbol A1 denotes a screw hole penetrating the bracket 1 in the thickness direction. The screw hole A1 is a screw hole for fixing the bracket 1 to the article M. In this embodiment, the bracket 1 can be firmly fixed to the article M using a fastening element such as a screw. As shown in FIGS. 3 and 4, in this embodiment, the bracket 1 further includes a base 13 fixed to the article M as the other end portion in the thickness direction that can be fixed to the article M, and the shaft portion 12 connects the insertion portion 11 and the base 13. Also, as shown in FIG. 5, in this embodiment, a plurality of recesses 13a are formed in the base 13. The recesses 13a can function as lightening portions for reducing the weight of the bracket 1A. In this case, the reduced weight of the bracket 1A makes it easier to attach and detach the bracket 1A, and therefore the article M, to and from the holder 2.

[0031] Figure 6 shows a schematic diagram of an exemplary item M attached to a worker's belt 30 using an item holder set 10A (hereinafter simply referred to as "set 10A"), which is a first embodiment of the present invention.

[0032] As shown in FIG. 6 , the set 10A includes a bracket 1 to which an article M is fixed and a holder 2 having an attachment portion 21. In this embodiment, the holder 2 is attached to a belt 30 worn by a worker. In this embodiment, the belt 30 is a shoulder belt worn vertically (up and down). However, the holder 2 may also be a waist belt or the like worn horizontally (left and right). In this embodiment, an access opening A21 of the attachment portion 21 provided on the holder 2 opens at the upper end of the holder 2. This allows the worker to insert the bracket 1 through the access opening A21 formed at the upper end of the holder 2, thereby holding the article M on the belt 30 via the holder 2. In addition, the worker can remove the bracket 1 fixed to the article M from the attachment portion 21 through the access opening A21, thereby separating the article M from the holder 2 attached to the belt 30 and, ultimately, from the worker.

[0033] FIG. 7 shows a schematic diagram of an article M attached to a stationary object 40 using an article holder set 10B (hereinafter simply referred to as "set 10B") according to a second embodiment of the present invention.

[0034] As shown in FIG. 7, set 10B, like set 10A, includes a bracket 1 to which item M is fixed, and a holder 2 having an attachment portion 21. In this embodiment, holder 2 is attached to a fixed object 40 (e.g., a wall of a building, or a plumbing pipe installed indoors or outdoors). Holder 2 can be fixed to the fixed object by, for example, adhesive, screws, bolts, or clamp elements. In this case, holder 2 can be handled separately from the worker, so that item M can be stored away from the worker when not in use.

[0035] FIG. 8 schematically shows a state in which an article M is attached to a movable object 50 using an article holder set 10C (hereinafter simply referred to as "set 10C") according to a third embodiment of the present invention.

[0036] As shown in Fig. 8, the set 10C, like the sets 10A and 10B, includes a bracket 1 to which an item M is fixed, and a holder 2 having an attachment portion 21. In this embodiment, the holder 2 is attached to or integrated with a movable object (e.g., a cart, a box) 50. In this case, the holder 2 can be separated from the worker while moving with the worker, allowing the worker to carry and store the item M without wearing it on their body.

[0037] FIG. 9 shows holder 2A, an example of a holder 2 that can be used in set 10 of the present invention, from the side of mounting portion 21. In FIG. 9, holder 2A is shown in a locked state. FIG. 10 is a right side view of holder 2A. FIG. 11 is a rear view of holder 2A. FIG. 12 shows holder 2A in a plan view from the side of loading / unloading opening A21 of mounting portion 21. FIG. 13 shows holder 2A in a perspective view from the side of loading / unloading opening A21.

[0038] Referring to FIG. 9 , the holder 2A includes a locking member 24 that secures the bracket 1 accommodated in the mounting portion 21. The locking member 24 is accommodated between the holder main body 2a and the holder cover 2b so as to be swingable in the thickness direction. In this embodiment, the guide 22 is provided on the holder main body 2a. In contrast, in this embodiment, the slide surface F21 is formed on the holder cover 2b. In this embodiment, a guide hole A2 penetrating the holder cover 2b in the thickness direction is formed on the slide surface F21 of the holder cover 2b. In this embodiment, the guide hole A2 has an upper guide hole portion A2a and a lower guide hole portion A2b, and the lower end of the upper guide hole portion A2a is connected to the lower guide hole portion A2b. As a result, the surface of the locking member 24 is exposed to the outside through the guide hole A2. In this embodiment, the width of the lower guide hole portion A2b is set wider than the width of the upper guide hole portion A2a. In this embodiment, the upper end of the upper guide hole portion A2a is an open end or a notched end at the upper end of the holder cover 2b, but the upper end of the holder cover 2b may be closed without being an open end.

[0039] The locking member 24 is provided with a claw portion 24a that protrudes toward the front side on the surface of the lower portion of the locking member 24. In addition, the locking member 24 is provided with a pressing portion 24b that can be pressed downward on the upper portion of the locking member 24. Furthermore, the locking member 24 is formed with an auxiliary slide surface F24 between the claw portion 24a and the pressing portion 24b, which allows the back surface of the insertion portion 11 of the bracket 1 to slide together with the slide surface F21. In this embodiment, a mounting bracket 25 for attaching a safety rope or the like is attached to the lower end of the holder 2A so as to be swingable in the thickness direction.

[0040] The holder 2A can be attached to a belt (band) 30 that extends vertically, like a shoulder belt. As shown in FIG. 10 , in this embodiment, the holder 2A has two belt holders 26 arranged vertically at a distance from each other on the back surface of the holder 2A. As shown in FIG. 11 , in this embodiment, the upper of the two belt holders 26 is a belt holder ring 26a that spans the width direction, and the lower belt holder 26 is composed of two belt holder hooks 26b that are arranged at a distance from each other in the width direction. As shown in FIG. 12 , the belt holder ring 26a forms a belt loop hole A30 for passing a belt 30 through. As shown in FIG. 13 , in this embodiment, a stopper 21s is arranged on the reinforcement portion 23 side of the mounting portion 21. The stopper 21s contacts the insertion portion 11 of the bracket 1 to limit the amount of insertion of the bracket 1 into the mounting portion 21.

[0041] FIG. 14 is a cross-sectional view taken along the line AA in FIG. 9. As shown in FIG. 14, in this embodiment, the claw portion 24a includes an upper inclined surface F24a1 and a lower inclined surface F24a2. In this embodiment, the connection between the upper inclined surface F24a1 and the lower inclined surface F24a2 forms a tip portion (ridge line) P24a of the claw portion 24a that faces the front side. Furthermore, the holder 2A includes a biasing member 27 that elastically biases the locking member 24 upward. In this embodiment, the biasing member 27 is a coil spring. The biasing member 27 is disposed between the holder main body 2a and the holder cover 2b. In this embodiment, the biasing member 27 is disposed between the holder main body 2a and the locking member 24 so as to bias the locking member 24 upward relative to the holder main body 2a. Furthermore, in this embodiment, the biasing member 27 is assembled in a compressed state between the holder main body 2a and the locking member 24. As a result, when locking member 24 is pressed downward relative to holder main body 2a via pressing portion 24b, it can be moved downward relative to holder main body 2a against the biasing force (elastic force) of biasing member 27. Furthermore, when the downward pressure on pressing portion 24b is released, locking member 24 moves upward relative to holder main body 2a due to the restoring force (biasing force) of biasing member 27, and can be moved back to its initial position before being pressed.

[0042] 15 is a cross-sectional view taken along the line BB in FIG. 9. The locking member 24 has slide rotation shafts 24c on both sides of the auxiliary slide surface F24 in the width direction, each of which protrudes outward in the width direction from the side surface of the locking member 24 (the auxiliary slide surface F24 of the locking member 24 is not shown in FIG. 15). In this embodiment, the slide rotation shaft 24c has an upper slide rotation surface F24c1 and a lower slide rotation surface F24c2. In this embodiment, the lower slide rotation surface F24c2 is continuous with the lower end P24 of the upper slide rotation surface F24c1. In this embodiment, the lower end P24 is a peak continuous with the upper slide rotation surface F24c1 and the lower slide rotation surface F24c2. In this embodiment, the upper slide rotation surface F24c1 is a curved surface formed with a curvature radius r1. In addition, in this embodiment, the lower slide rotation surface F24c2 is a curved surface formed with a curvature radius r2. In this embodiment, the radius of curvature r2 is greater than the radius of curvature r1.

[0043] Meanwhile, the holder cover 2b is formed with a guide surface F2b on which the slide rotation shaft 24c provided on the locking member 6 is slidably disposed. The guide surface F2b is inclined downward toward the rear surface (holder main body 2a) of the holder 2A. The slide rotation shaft 24c of the locking member 24 can slide up and down while rotating on the guide surface F2b.

[0044] Figure 16 shows a state in which the holder 2A is unlocked, corresponding to the cross section BB in Figure 9. As shown in Figure 16, when the locking member 24 is pressed downward, the claw portion 24a of the locking member 24 swings around the slide rotation shaft 24c toward the rear surface of the locking member 24 (the holder main body 2a), and the claw portion 24a is accommodated through the guide hole A2 on the rear surface (the holder main body 2a) side of the locking member 24 relative to the slide surface F21. In contrast, when the pressure on the locking member 24 is released, the restoring force of the biasing member 27 causes the claw portion 24a of the locking member 24 to swing around the slide rotation shaft 24c toward the front surface of the holder 2A (the slide surface F21), and as a result, the claw portion 24a protrudes from the slide surface F21 to the front side through the guide hole A2, as shown in Figure 15.

[0045] Next, an exemplary method of operating the holder 2A will be described.

[0046] [Installation of items] 14, for example, bracket 1 fixed to article M is inserted into mounting portion 21 from the top of holder 2A through inlet / outlet port A21. At this time, the movement of insertion portion 11 of bracket 1 in the width direction is restricted by guide wall 22a, and the movement in the thickness direction is restricted by guide hook 22b and slide surface F21. As a result, bracket 1 fixed to article M slides downward along the two guides 22.

[0047] Here, as shown in Fig. 14, in the initial state of the holder 2A before the bracket 1 is attached, the claw portion 24a of the locking member 24 protrudes from the slide surface F21 of the locking member 24. At this time, the slide rotation shaft 24c of the locking member 24 is located above the guide surface F2b formed on the holder cover 2b, as shown in Fig. 15. In contrast to this, referring to Fig. 14, when the bracket 1 slides from above along the guide 22, the insertion portion 11 of the bracket 1 passes through the auxiliary slide surface F24 of the locking member 24 and reaches the upper inclined surface F24a1 of the claw portion 24a, and then presses the upper inclined surface F24a1 of the claw portion 24a downward and toward the surface (slide surface F21) of the holder 2A. 16, the slide rotation shaft 24c of the locking member 24 slides downward while rotating on the guide surface F2b, causing the claw portion 24a of the locking member 24 to move downward relative to the holder main body 2a against the elastic force of the biasing member 27 and swing so as to sink closer to the holder main body 2a than the slide surface F21. As a result, the bracket 1, which has slid downward together with the article M, can pass through the claw portion 24a provided on the locking member 24 by sinking the claw portion 24a.

[0048] After the bracket 1 passes through the claw portion 24a, the bracket 1 is released from the locking member 24, and the locking member 24 is urged upward by the elastic force of the urging member 27. This causes the locking member 24 to return to its initial state, and the claw portion 24a of the locking member 24 can automatically protrude from the slide surface F21, as shown in FIG. 14. Furthermore, in this embodiment, the bracket 1 that has passed through the claw portion 24a comes into contact with the stopper 21s shown in FIG. 13. As a result, the bracket 1 is supported from below by the stopper 21s, while being prevented from coming off from above by the claw portion 24a provided on the locking member 24. Therefore, with the holder 2A, even if the article M is subjected to a large impact due to unexpected contact or the like, the bracket 1 can be prevented from falling off the holder 2A against the user's intention.

[0049] [Removal of items] When the article M is attached to the holder 2A, as shown in FIG. 14, the holder 2A (locking member 24) is in an initial state in which the claw portion 24a protrudes from the slide surface F21.

[0050] When removing the article M from the holder 2A, the pressing portion 24b of the locking member 24 is pressed downward relative to the holder main body 2a against the elastic force of the biasing member 27. In this case, too, the slide rotation shaft 24c slides downward while rotating on the guide surface F2b, so that the claw portion 24a of the locking member 24 sinks closer to the holder main body 2a than the slide surface F21, as shown in Fig. 16. This allows the article M to be removed together with the bracket 1 from the holder 2A by pulling the article M upward along the two guides 22.

[0051] After the bracket 1 is removed from the holder 2A, when the pressure on the pressing portion 24b of the locking member 24 is released, the locking member 24 is urged upward relative to the holder main body 2a by the elastic force of the urging member 27. This causes the locking member 24 to return to its initial state, and as shown in Fig. 14, the claw portion 24a of the locking member 24 can automatically protrude from the slide surface F21.

[0052] Therefore, with the holder 2A, the article M can be repeatedly attached and detached by automatically fixing it to the mounting portion 21 via the bracket 1 and then forcibly releasing the fixing by operating the locking member 24.

[0053] 17 shows a holder 2B, which is another example of an article holder that can be used in the article holder set 10 of the present invention, from the side of the attachment portion 21. However, in FIG. 17, the holder 2B is shown in a locked state.

[0054] The holder 2B includes a locking member 28 that is slidable diagonally up and down relative to the holder main body 2a. The locking member 28 can be moved outward in the width direction as it moves downward relative to the holder main body 2a. Conversely, the locking member 28 can be moved inward in the width direction as it moves upward relative to the holder main body 2a. In this embodiment, the locking member 28 is biased diagonally upward relative to the holder main body 2a by a biasing member (not shown) such as a coil spring. The gap between the two guides 22 of the loading / unloading opening A21 of the mounting portion 21 is narrowed by a locking protrusion 28a provided on the inner side of the locking member 28 in the width direction. As a result, in the initial state (state shown in FIG. 17 ) in which the locking member 28 is biased by the biasing member, the bracket 1 is fixed to the mounting portion 21. However, when the locking member 28 is pressed diagonally downward relative to the holder main body 2a against the biasing force of the biasing member, the bracket 1 can be removed from the mounting portion 21. When the locking member 28 is released from the depressed state, the locking member 28 can automatically return to its initial state due to the biasing force of the biasing member.

[0055] [Bracket evaluation] By changing the width W11 of the insertion portion of the bracket, an evaluation test was conducted on two items: the feeling of use when attaching and detaching the bracket to the holder 2, and the tensile strength of the bracket. The evaluation results are shown below.

[0056] Subjects: 30 in-house workers sample: (1) Bracket Five samples were used, each with the same insertion portion thickness (height of the insertion portion in the direction of the bracket central axis) D11 (D11 = 2 mm), shaft thickness (height of the shaft portion in the direction of the bracket central axis) D12 (D12 = 4.3 mm), and insertion portion protrusion from the shaft (flange width) Δ11 (Δ11 = 2 mm), but with different insertion portion diameters R1. Samples 1 to 5 had R1 = 10 mm to 50 mm, respectively, and R2 = 6 mm, 16 mm, 26 mm, 36 mm, and 46 mm, respectively. (2) Holder A different holder was used for each of bracket samples 1 to 5. For each of bracket samples 1 to 5, the width W21 of the guide hook was set to 6 mm, 16 mm, 26 mm, 36 mm, and 46 mm.

[0057] Evaluation items: usability, tensile strength Evaluation method: 5-point scale

[0058] Usability: Brackets with different insertion widths were attached to the same tool (tape measure), and each bracket was attached and detached to the same holder, and the subject evaluated the usability on a 5-point scale. The specific evaluation details are as follows:

[0059] [Table 1]

[0060] Tensile strength: The protruding portion (flange) of the bracket insertion portion was pulled vertically (towards the central axis of the bracket) or in a torsional direction (around the central axis of the bracket), and the strength test results were evaluated on a 5-point scale. As shown in Figure 18A, a tensile force F was applied to the flange 11a in a direction that pulled the bracket 1 away from the article M. Specifically, as shown in Figure 18B, the tensile force was applied from the back surface of the flange 11a located on both sides of the bracket 1 in the width direction toward the upper side. Samples 1 to 5, which were similar to those used for the brackets, were used. The specific evaluation details are as follows:

[0061] [Table 2]

[0062] The following table summarizes the evaluation results for each of Samples 1 to 5.

[0063] [Table 3]

[0064] The graph in FIG. 20 shows the results of evaluating the usability and tensile strength of the article holder set in relation to the diameter of the insertion portion of the bracket.

[0065] As is clear from Table 3 and the graph of FIG. 20, the best usability is achieved when the diameter R1 of the outer edge contour of the insertion portion is 20 mm. In contrast, the tensile strength of the bracket 1, particularly the tensile strength of the central portion of the insertion portion (see, for example, FIG. 18B), tends to be insufficient to support the tensile force F when the diameter R1 of the insertion portion 11 is small. Furthermore, when the diameter R1 is large, the flange 11a tends to bend, as shown in FIG. 19. Therefore, it was found that setting the radius R1 of the insertion portion to approximately 18 to approximately 25 mm provides excellent tensile strength and provides an excellent usability when attaching and detaching the insertion portion to the article holder, and that setting the diameter R1 of the insertion portion to greater than 20 mm is particularly preferable.
