DETAILED DESCRIPTION OF THE INVENTION
[0015] 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.
[0016] 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").
[0017] 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.
[0018] 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.
[0019] 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.
[0020] 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 inner widthwise spacing between the two guide hooks 22b, is indicated by width W21. Specifically, width W21 is the widthwise dimension between the widthwise 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 D2 is the dimension between the slide surface F21 and the back surface F22b of the guide hook 22b in the thickness direction.
[0021] 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.
[0022] 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.
[0023] 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.
[0024] 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 shaft 12 side.
[0025] As shown in FIG. 2 , in this embodiment, the insertion portion 11 has a rectangular outer edge contour shape in a plan view. In this embodiment, the insertion portion 11 has two widthwise side surfaces F1 spaced apart in the width direction and two lengthwise side surfaces F2 spaced apart in the lengthwise direction. As a result, in this embodiment, the insertion portion 11 has a rectangular outer edge contour shape as shown in FIG. 2 . In this embodiment, the corner surface F3 between the widthwise side surfaces F1 and the lengthwise side surfaces F2 is configured as an outwardly protruding curved surface. That is, in this embodiment, the insertion portion 11 has a rectangular outer edge contour shape with outwardly curved corners. When the corner surface F3 of the insertion portion 11 is configured as a curved surface, as in this embodiment, the insertion portion 11 can be easily inserted into and removed from the mounting portion 21. However, between the width direction side surface F1 and the length direction side surface F2, an edge (right-angled outer edge contour shape) can be formed by directly connecting the width direction side surface F1 and the length direction side surface F2, rather than by a corner surface F3.
[0026] In addition, as shown in Fig. 2, the insertion portion 11 has an area larger than the area of the shank 12. In this embodiment, as shown in Fig. 2, the area surrounded by the outer edge contour shape of the insertion portion 11 is larger than the area surrounded by the outer edge contour shape of the shank 12.
[0027] As shown in FIG. 2, in this embodiment, the shank 12 also has a rectangular outer edge contour. In this embodiment, the shank 12 has two widthwise side surfaces F5 spaced apart in the width direction and two lengthwise side surfaces F6 spaced apart in the lengthwise direction. As a result, as shown in FIG. 2, the shank 12 has a rectangular outer edge contour. Similar to the insertion portion 11, a corner surface F7 formed by an outwardly protruding curved surface is connected between the widthwise side surface F5 and the lengthwise side surface F6. That is, in this embodiment, the shank 12 also has a rectangular outer edge contour with outwardly curved corners. When the corner surface F7 of the shank 12 is formed by a curved surface, as in this embodiment, the shank 12 can be easily inserted into and removed from the attachment portion 21. However, as with the insertion portion 11, the area between the widthwise side surface F5 and the lengthwise side surface F6 can also be formed into an edge (a right-angled outer edge contour shape) by directly connecting the widthwise side surface F5 and the lengthwise side surface F6 rather than using a corner surface F7.
[0028] As shown in FIG. 2, in this embodiment, the area enclosed by the outer edge contour shapes (F1, F2, F3) of the insertion portion 11 is larger than the area enclosed by the outer edge contour shapes (F5, F6, F7) of the shank 12. In FIG. 2, reference symbol W11 denotes the width between the two widthwise side surfaces F1 of the insertion portion 11. Specifically, the width W11 is the widthwise dimension between the two widthwise side surfaces F1 of the insertion portion 11. Furthermore, reference symbol L11 denotes the vertical (lengthwise) length of the insertion portion 11. Specifically, the length L11 is the vertical dimension between the two lengthwise side surfaces F2 of the insertion portion 11. In contrast, reference symbol W12 denotes the width between the two widthwise side surfaces F5 of the shank 12. Specifically, the width W12 is the widthwise dimension between the two widthwise side surfaces F5 of the shank 12. Furthermore, reference symbol L12 is the vertical (lengthwise) length of the shank 12. Specifically, the length L12 is the vertical dimension between the two longitudinal side surfaces F6 of the shaft portion 12.
[0029] In addition, as shown in FIG. 2, the shank 12 according to this embodiment is disposed relative to the inserting portion 11 so that the outer edge of the inserting portion 11 forms an endless flange 11a over the entire periphery.
[0030] As shown in Fig. 2, in this embodiment, the insertion portion 11 and the shaft portion 12 each have a square outer edge contour shape, so that the flange 11a in this embodiment is shaped as an endless regular square flange.
[0031] Specifically, the outer edge contour shapes 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.
[0032] The widthwise side surface F1 of the insertion portion 11 is a side surface corresponding to one side of the rectangular outer edge contour shape. The widthwise side surface F1 of the insertion portion 11 is a side surface that faces the inner surface F22a of the guide wall 22a when the insertion portion 11 is inserted into the attachment portion 21. Here, the width W11 between the two widthwise side surfaces F1 of the insertion portion 11 (hereinafter simply referred to as the "width W11 of the insertion portion 11") is the widthwise dimension between the two widthwise side surfaces F1 of the insertion portion 11. 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 width W11 of the insertion portion 11 is 18 mm or more and 25 mm or less, i.e., 18 mm ≦ W11 ≦ 25 mm. More preferably, it is 20 mm ≦ W11 ≦ 24 mm.
[0033] The bracket 1A has a rectangular outer contour shape for the insertion portion 11. This allows the item M to be carried or stored while maintaining a fixed orientation relative to the holder 2 when attached to the holder 2. Therefore, the bracket 1A is effective for holding an item M that must be used in a specific orientation (e.g., a directional tool or precision instrument). Furthermore, by preventing rotation relative to the holder 2, the item M can be prevented from having a large amount of play within the holder 2, which could cause the item M to wobble or become unstable. This improves safety and efficiency during work. Furthermore, preventing the item M from wobbling or becoming unstable reduces the load on the item M, which is expected to improve the durability of the item M. Furthermore, when the bracket 1A is attached to the holder 2, the orientation of the item M relative to the holder 2 is always fixed, allowing for smooth removal from the holder 2. This minimizes interruptions to work and supports efficient work.
[0034] The bracket 1 can be used to fix the item M, for example, when a precision instrument (e.g., a measuring instrument or an inspection instrument) is used as the item M. Examples of the item M that needs to be used in a specific orientation include a camera, a light, etc.
[0035] Furthermore, with bracket 1A, by setting the width W11 of insertion portion 11 to 18 mm≦W11≦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 W11 is set to 20 mm≦W11≦24 mm, the tensile strength is improved when bracket 1A is attached to holder 2 and pulled from holder 2.
[0036] As shown in Fig. 2, in this embodiment, the shank 12 is disposed relative to the insertion portion 11 so that the outer edge of the insertion portion 11 forms an endless flange 11a around the entire periphery. In this case, as shown in Fig. 2, not only can the two flanges 11a1 that face each other across the shank 12 in the width direction serve as guides for the two guides 22 provided on the holder 2, but also the two flanges 11a2 that face each other across the shank 12 in the length direction serve as guides for the two guides 22 provided on the same or different holders 2.
[0037] 2, in this embodiment, the insertion portion 11 and the shank 12 each have a square outer edge contour shape, and the flange 11a protrudes outward from the shank 12 by an equal width around the entire circumference of the central axis O. In this case, for the same holder 2, the two flanges 11a1 can serve as guides for the two guides 22 provided on the holder 2, and the two flanges 11a2 can also serve as guides for the two guides 22 provided on the holder 2.
[0038] FIG. 3 shows a detachable article holder bracket 1B (hereinafter simply referred to as "bracket 1B") according to a second embodiment of the present invention, viewed from the shaft 12 side of the bracket 1B, similar to FIG.
[0039] As shown in Fig. 3, in this embodiment, shank 12 is also disposed relative to insert portion 11 in a plan view such that the outer edge of insert portion 11 forms an endless flange 11a around the entire periphery, similar to bracket 1A. However, in bracket 1B, insert portion 11 and shank 12 each have a rectangular outer edge contour shape, as shown in Fig. 3. As a result, in this embodiment, flange 11a is shaped as a rectangular, endless flange.
[0040] Specifically, in this embodiment, the insert portion 11 and the shank 12 have similar outer edge contour shapes and are also positioned in the same longitudinal and lateral directions. Furthermore, in this embodiment, the central axis of the insert portion 11 and the central axis of the shank 12 are the same central axis O, as in the bracket 1A. As a result, the flange 11a protrudes outward from the shank 12 by an equal width around the entire circumference of the central axis O.
[0041] 3, in this embodiment, the insertion portion 11 and the shank 12 each have a rectangular outer edge contour shape, and the flange 11a protrudes outward from the shank 12 by an equal width around the entire circumference of the central axis O. In this case, for two different types of holders 2 in which the widthwise spacing W21 between two guide hooks 22b provided on the holders 2 is different, the two flanges 11a1 can serve as guides for the two guides 22 provided on one holder 2, and the two flanges 11a2 can also serve as guides for the two guides 22 provided on the other holder 2.
[0042] FIG. 4 shows a detachable article holder bracket 1C (hereinafter simply referred to as "bracket 1C") according to a third embodiment of the present invention, viewed from the side of the shaft 12 of the bracket 1C.
[0043] 4, in this embodiment, the shank 12 is arranged on the insertion portion 11 so that, in a plan view, parts of the outer edge of the insertion portion 11 form two flanges 11a facing each other across the shank 12. As a result, in this embodiment, the flange 11a is composed of two flanges 11a1 arranged in the width direction. Furthermore, each of the two flanges 11a1 is shaped as a rectangular flange extending in the vertical direction.
[0044] Specifically, in this embodiment, the insertion portion 11 has a square outer edge contour shape, and the shank 12 has a rectangular outer edge contour shape. As shown in FIG. 4, in this embodiment, the shank 12 is arranged so that the longitudinal direction of the shank 12 is parallel to the up-down direction. 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 in the bracket 1A. As a result, the two flanges 11a each protrude outward from the shank 12 by an equal width, sandwiching the shank 12 therebetween.
[0045] As shown in Fig. 4, in this embodiment, the shank 12 is arranged on the insertion portion 11 so that parts of the outer edge of the insertion portion 11 form two flanges 11a1 that face each other with the shank 12 in between. In this case, by reducing the vertical length of the bracket 1C, it is possible to achieve a more compact size in the vertical direction (longitudinal direction). In this embodiment, as shown in Fig. 4, the vertical length L11 of the insertion portion 11 and the vertical length L12 of the shank 12 are the same length, thereby achieving a further vertical reduction in size.
[0046] FIG. 5 shows a detachable article holder bracket 1D (hereinafter simply referred to as "bracket 1D") according to a fourth embodiment of the present invention, viewed from the side of the shaft 12 of the bracket 1D.
[0047] As shown in FIG. 5, in this embodiment, the shaft portion 12 is disposed on the insertion portion 11 so that a part of the outer edge of the insertion portion 11 forms a U-shaped flange 11b in a plan view.
[0048] Specifically, in this embodiment, the insertion portion 11 and the shank 12 each have a rectangular outer edge contour shape. Furthermore, as shown in FIG. 5, in this embodiment, the shank 12 is arranged so that the longitudinal direction of the shank 12 and the longitudinal direction of the insertion portion 11 are parallel to the up-down direction. However, as shown in FIG. 5, in this embodiment, the central axis O1 of the insertion portion 11 and the central axis O2 of the shank 12 are arranged at different positions in the up-down direction. This results in a U-shaped flange 11b formed by two vertical portions 11b1 spaced apart in the width direction and a connecting portion 11b2 connected to one end of these two vertical portions 11b1 in the width direction.
[0049] As shown in FIG. 5 , in this embodiment, the shank 12 is disposed on the insertion portion 11 so that a portion of the outer edge of the insertion portion 11 forms a U-shaped flange 11b. In this case, when the bracket 1D is attached to the holder 2, the movement of the connecting portion 11b1 of the flange 11b in the thickness direction is further restricted by the reinforcing portion 23 of the mounting portion 21 provided on the holder 2 and the sliding surface F21, thereby further strengthening the attachment of the bracket 1 to the holder 2. In addition, as in this embodiment, an inwardly recessed recessed surface F4 can be formed in the outer edge contour shape of the connecting portion 11b1 of the flange 11b. In this case, with the bracket 1D attached to the mounting portion 21 of the holder 2, a positioning portion provided on the holder 2 can be fitted into the recessed surface F4, thereby positioning the bracket 1D relative to the mounting portion 21 in the width direction of the mounting portion 21.
[0050] FIG. 6 shows a detachable article holder bracket 1E (hereinafter simply referred to as "bracket 1E") according to a fifth embodiment of the present invention, viewed from the side of the shaft 12 of the bracket 1E.
[0051] In this embodiment, similar to the bracket 1D, the shank 12 is disposed on the insertion portion 11 so that a portion of the outer edge of the insertion portion 11 forms a U-shaped flange 11b. However, as shown in FIG. 6, in the bracket 1E, the corner surface F9 between the widthwise side surface F1 and the lengthwise side surface F2 of the insertion portion 11 is configured as a tapered surface that forms a linear outer edge contour shape that slopes inward in the width direction as it approaches the bottom in a plan view. Also, as shown in FIG. 6, the bracket 1E has an inclined surface F8 that slopes inward in the width direction from the widthwise side surface F1 toward the corner 3 between the widthwise side surface F1 and the corner 3. This allows the bracket 1E to be easily inserted into and removed from the mounting portion 21. Furthermore, in this embodiment, the shank 12 has multiple recesses 13 formed therein. The recesses 13 can function as lightening portions to reduce the weight of the bracket 1E. In this case, the reduced weight of the bracket 1E allows the bracket 1E, and therefore the article M, to be easily attached to and detached from the holder 2. Note that reference symbol A1 denotes a screw hole that penetrates the bracket 1E in the thickness direction. The screw hole A1 is a screw hole for fixing the bracket 1E to the article M. In this embodiment, the bracket 1E can be firmly fixed to the article M by using a fastening element such as a screw, similar to the bracket 1A.
[0052] Figure 7 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.
[0053] As shown in FIG. 7 , 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.
[0054] FIG. 8 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.
[0055] As shown in FIG. 8, 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 placed 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.
[0056] FIG. 9 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.
[0057] 9, set 10C, like 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, holder 2 is attached to or integrated with a movable object (e.g., a dolly, a box) 50. In this case, holder 2 can be separated from a worker while moving with the worker, allowing the worker to carry and store item M without wearing the item M on their body.
[0058] FIG. 10 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. 10, holder 2A is shown in a locked state. FIG. 11 is a right side view of holder 2A. FIG. 12 is a rear view of holder 2A. FIG. 13 shows holder 2A in a plan view from the side of loading / unloading opening A21 of mounting portion 21. FIG. 14 shows holder 2A in a perspective view from the side of loading / unloading opening A21.
[0059] Referring to FIG. 10 , the holder 2A includes a locking member 24 that secures the bracket 51 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.
[0060] 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.
[0061] The holder 2A can be attached to a belt (band) 30 that extends vertically, like a shoulder belt. As shown in FIG. 11 , in this embodiment, the holder 2A includes two belt holders 26 arranged vertically at a distance from each other on the back surface of the holder 2A. As shown in FIG. 12 , 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. 13 , the belt holder ring 26a forms a belt loop A30 through which the belt 30 is passed. As shown in FIG. 14 , in this embodiment, a stopper 21s is arranged on the reinforcing 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.
[0062] FIG. 15 is a cross-sectional view taken along the line AA in FIG. 10. As shown in FIG. 15, 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.
[0063] FIG. 16 is a cross-sectional view taken along the line BB in FIG. 10. 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. 16). 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 an apex 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.
[0064] 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.
[0065] Fig. 17 shows a state in which the lock of holder 2A is released, corresponding to the cross section BB in Fig. 10. As shown in Fig. 17, when locking member 24 is pressed downward, claw portion 24a of locking member 24 pivots around slide rotation shaft 24c as a base point toward the rear surface of locking member 24 (holder main body 2a), and claw portion 24a is accommodated through guide hole A2 on the rear surface (holder main body 2a) side of locking member 24 relative to slide surface F21. In contrast, when the pressure on locking member 24 is released, claw portion 24a of locking member 24 pivots around slide rotation shaft 24c as a base point toward the front surface of holder 2A (slide surface F21) due to the restoring force of biasing member 27, and as a result, claw portion 24a protrudes from slide surface F21 to the front side through guide hole A2.
[0066] Next, an exemplary method of operating the holder 2A will be described.
[0067] [Installation of items] 15, for example, bracket 1 fixed to article M is inserted into mounting portion 21 from the top of holder 2A through loading / unloading opening 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.
[0068] Here, as shown in Fig. 15, 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. 16. In contrast to this, referring to Fig. 15, 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. 17, 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.
[0069] 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. 15. 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. 4. 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, according to 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.
[0070] [Removal of items] When the article M is attached to the holder 2A, as shown in FIG. 15, the holder 2A (locking member 24) is in an initial state in which the claw portion 24a protrudes from the slide surface F21.
[0071] 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. 17. 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.
[0072] 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. 15, the claw portion 24a of the locking member 24 can automatically protrude from the slide surface F21.
[0073] 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.
[0074] 18 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. 18, the holder 2B is shown in a locked state.
[0075] 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. 18 ) 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.
[0076] [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.
[0077] Subjects: 30 in-house workers Sample: Five samples were used for the bracket, with the same insertion portion thickness (height of the insertion portion in the bracket central axis direction) D11 (D11 = 2 mm), shaft thickness (height of the shaft portion in the bracket central axis direction) D12 (D12 = 4.5 mm), and insertion portion protrusion amount from the shaft (flange width) Δ11 (Δ11 = 2 mm), but with different insertion portion widths W11. Samples 1 to 5 had W11 = 10 mm to 50 mm, respectively. Evaluation items: usability, tensile strength Evaluation method: 10-point rating (1: inappropriate → 10: optimal) 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 subjects rated the usability on a 10-point scale. Tensile strength: The protruding part (flange) of the bracket insertion part was pulled vertically (towards the central axis of the bracket) or in the torsional direction (around the central axis of the bracket), and the strength test results were evaluated on a 10-point scale. Brackets with W11 = 10mm to 50mm were used, similar to the usability test.
[0078] The following table summarizes the evaluation results for each of Samples 1 to 5.
[0079] [Table 1]
[0080] The graph in FIG. 19 shows the results of evaluating the usability and tensile strength of the article holder set in relation to the width of the insertion portion of the bracket.
[0081] As is clear from the table and the graph in Figure 19, the tensile strength increases as the width W11 of the insertion part increases, but conversely, the evaluation of the usability decreases. It was also found that the width W11 of the insertion part is suitable for use when the strength is between about 18 and about 21.
[0082] The above is a description of exemplary embodiments of the present invention, and various modifications can be made without departing from the scope of the claims. The various configurations employed in the above-described embodiments can be combined with each other. [Explanation of symbols]
