[Figure 39] FIG. 1 is a front view of an exemplary item, a spirit level. [Figure 40] FIG. 40 is a side view of the spirit level of FIG. 39. DETAILED DESCRIPTION OF THE INVENTION

[0021] Hereinafter, an article holder according to an exemplary embodiment of the present invention will be described with reference to the drawings.

[0022] In the following description, "upper" and "lower" refer to the state in which the item holder is worn by a user. For example, "upper side" refers to the upper side as seen from the perspective of a user wearing the item holder, and "lower side" refers to the lower side as seen from the perspective of a user wearing the item holder. "Front" and "back" also refer to the state in which the item holder is worn by a user. For example, "front side" refers to the side farther from the body of a user wearing the item holder, and "back side" refers to the side closer to the body of a user wearing the item holder. Furthermore, "left" and "right" also refer to the state in which the item holder is worn by a user. For example, "left side" refers to the left side as seen from the perspective of a user wearing the item holder, and "right side" refers to the side as seen from the perspective of a user wearing the item holder.

[0023] The article holder can be used when a user carries an article. The article holder can be attached to a belt worn by the user around the waist, for example. A bracket provided on the article to be carried can be removably attached to the article holder. This allows the user to removably carry various articles.

[0024] Portable items include, for example, tools used at construction sites, etc. Specific examples of construction tools include hammers, crowbars, ratchet wrenches, electric screwdrivers, tape measures, levels, saws, and other sharp tools. The item holder is effective for long items such as levels.

[0025] FIG. 39 shows a level 100 as an exemplary article from its front side. Here, the front side of the level 100 refers to the side that faces the user when the level 100 is in use, and the back side of the level 100 refers to the opposite side. The level 100 is a long tool equipped with a plurality of vials 110. The level 100 has a recess 112 recessed from the front side to the back side of the level 100 on the right side as viewed from the front of the level 100. The recess 112 has a metal fitting attachment portion 113. The level 100 also has a recess 114 recessed from the front side to the back side of the level 100 on the left side as viewed from the front of the level 100. A bracket 115 is provided in the recess 114. The bracket 115 includes a pillar portion 116 that passes through a through-hole 114a formed in the recess portion 114, and flanges 117 that are provided on both the front and rear ends of the pillar portion 116.

[0026] FIG. 40 shows the level 100 from the left side as viewed from the front of the level 100. The bracket 115 has an elastically deformable expanded diameter portion 116a on a post 116. The expanded diameter portion 116a is hooked and engaged so as to be able to ride over an edge 114e formed on a step 114 that defines the through-hole 114a. When the level 100 is in use, the front side of the bracket 115 protrudes toward the front side as shown by the solid line in the figure, and a flange 117 on the back side of the bracket 115 is housed inside the level 100 as shown by the dashed line. When the level 100 is carried, the front flange 117 of the bracket 115 is pushed toward the back side, causing the expanded diameter portion 116a of the post 116 to ride over the edge 114e formed on the step 114, and the flange 117 on the back side of the bracket 115 to protrude toward the back side as shown by the two-dot chain line. In this embodiment, the spirit level 100 can be attached to the bracket holder 2 by making the bracket 115 protrude from the rear side.

[0027] FIG. 1 shows an article holder 1A according to a first embodiment of the present invention. In FIG. 1, the front side of the article holder 1A is shown from the upper right side. In addition, FIG. 2 shows the back side of the article holder 1A of FIG. 1 from the left side. Furthermore, FIG. 3 shows the article holder 1A of FIG. 1 from the left side.

[0028] The article holder 1A includes a bracket holder 2 to which a bracket 115 provided on the level 100 can be attached and detached, and a belt holder 3 disposed on the back side of the bracket holder 2.

[0029] Referring to Figure 1, the bracket holder 2 has a mounting portion 24 for mounting a bracket 115 provided on the spirit level 100, and a stopper member 23 for removably fixing the bracket 115 attached to the mounting portion 24.

[0030] The mounting portion 24 includes a guide surface F2 extending in the lengthwise direction (vertical direction) and two guide flanges 25 also extending in the lengthwise direction. A gap is formed between the guide surface F2 and the two guide flanges 25 in the thickness direction (front-to-back direction) to accommodate a flange 117 of a bracket 115 provided on the level 100. In addition, the two guide flanges 25 are spaced apart in the widthwise direction (left-to-right direction). A column portion 116 of the bracket 115 provided on the level 100 can be passed between the two guide flanges 25 in the lengthwise direction. The mounting portion 24 has an attachment opening A24 for inserting the bracket 115 by opening one end (upper end) of the two guide flanges 25 in the lengthwise direction. In this embodiment, the attachment opening A24 is formed so as to open upward when the article holder 1A is suspended from the belt, for example, as shown in FIG. 1 . As a result, the bracket 115 provided on the spirit level 100 can be inserted into the mounting portion 24 using the two guide flanges 25 as a guide after passing through the mounting opening A24 from the top side of the item holder 1A while the item holder 1A is suspended.

[0031] In addition, the mounting portion 24 is provided with a bracket insertion limiting portion 27 for limiting the insertion of a bracket 115 provided on the level 100. In this embodiment, the bracket insertion limiting portion 27 is a protrusion that protrudes from the guide surface F2 toward the front side. The bracket 115 provided on the level 100 is guided into the mounting portion 24 along the two guide flanges 25, and then comes into contact with the bracket insertion limiting portion 27, thereby being positioned in the longitudinal direction relative to the mounting portion 24. As a result, the bracket 115, with the article holder 1A suspended therefrom, moves downward inside the mounting opening A24, as shown in FIG. 1, and is then positioned at a predetermined position inside the mounting opening A24.

[0032] In addition, the mounting portion 24 includes a connecting flange 26 that connects the other longitudinal end portions (lower end portions) of the two guide flanges 25 in the width direction. The connecting flange 26 reinforces the two guide flanges 25 and also protects the bracket insertion limiting portion 27 by covering it.

[0033] In this embodiment, the bracket holder 2 includes a base 21 extending in the longitudinal direction and a cover 22 that covers the front side of the base 21. In this embodiment, the guide surface F2 is a flat surface formed on the front side of the base 21. In this embodiment, the guide flange 25 and the connecting flange 26 are provided on the cover 22.

[0034] The stopper member 23 prevents the bracket 115 accommodated in the mounting opening A24 from coming off the mounting portion 24 by essentially narrowing the mounting opening A24. In this embodiment, the stopper member 23 is disposed in front of (above) the mounting opening A24 in the longitudinal direction. The stopper member 23 can slide in the width direction relative to the guide surface F2. In this embodiment, as shown in FIG. 1, the stopper member 23 can move diagonally downward and upward to the left while suspending the article holder 1A. In this embodiment, the stopper member 23 is biased diagonally upward and to the left by, for example, an elastic element such as a spring (not shown). As a result, the stopper member 23 essentially narrows the widthwise spacing of the mounting opening A24 in front of the mounting opening A24 in an initial state in which the stopper member 23 is not in operation. Therefore, when the stopper member 23 is in the initial state, the pillar portion 116 of the bracket 115 housed in the mounting portion 24 is held by the stopper member 23 so as not to come out of the mounting opening A24. Therefore, when the stopper member 23 is in the initial state, the level 100 can be attached to the bracket holder 2 without falling out. On the other hand, if the stopper member 23 is moved diagonally downward to the left against the biasing force (elastic force) of the elastic element, the mounting opening A24 can be opened. Therefore, the pillar portion 116 of the bracket 115 can be removed from the mounting portion 24 through the mounting opening A24 by pushing down the stopper member 23. Therefore, the level 100 can be removed from the bracket holder 2 by operating the stopper member 23.

[0035] According to the bracket holder 2, the level 100 can be moved downward toward the mounting opening A24 together with the bracket 115, guided by the guide surface F2. The bracket 115 then guides the two guide flanges 25 into the mounting portion 24 through the mounting opening A24 by the pillar portion 116 of the bracket 115 moving the stopper member 23 diagonally downward and left against the elastic force of the elastic element. However, after the pillar portion 116 of the bracket 115 passes through the stopper member 23, the stopper member 23 returns to its initial state due to the elastic force of the elastic element. In this way, the stopper member 23 essentially narrows the mounting opening A24, thereby preventing the bracket 115 from being removed from the mounting opening A24. Therefore, a user can attach the level 100 to the bracket holder 2 without it falling off by simply inserting the bracket 115 provided on the level 100 downward toward the mounting opening A24.

[0036] On the other hand, when removing the spirit level 100 from the bracket holder 2, the user slides the stopper member 23 diagonally downward to the left against the elastic force of the elastic element, thereby essentially widening the mounting opening A24 and releasing the stopper member 23. This allows the user to easily remove the spirit level 100 from the bracket holder 2 by pulling up the spirit level 100 while pressing the stopper member 23 diagonally downward to the left.

[0037] On the other hand, the belt holder 3 has a belt attachment hole A3 for attaching to the belt. The belt attachment hole A3 opens to the right as shown in Fig. 1 and to the left as shown in Fig. 2. As a result, the belt attachment hole A3 penetrates the belt holder 3 in the width direction (left-right direction) as shown in Fig. 3. A user can attach the article holder 1A to the belt by attaching the belt to the belt attachment hole A3 provided in the belt holder 3.

[0038] In this embodiment, the belt holder 3 is made up of two parts.

[0039] In this embodiment, the belt holder 3 is composed of a front part 4 as a front part arranged on the back side of the bracket holder 2, and a back part 5 as a back part arranged on the back side of the front part 4. In this embodiment, the belt attachment hole A3 is formed between the front part 4 and the back part 5.

[0040] In addition, the bracket holder 2 is rotatably connected to the belt holder 3 so as to open toward the front side relative to the belt holder 3.

[0041] 1 and 2, the belt holder 3 has two boss protrusions 3a spaced apart in the width direction for rotatably connecting the bracket holder 2. The bracket holder 2 also has one boss protrusion 2a disposed between the two boss protrusions 3a for rotatably connecting the belt holder 3.

[0042] In this embodiment, the bracket holder 2 and the belt holder 3 are connected by a support shaft 6 so as to be rotatable relative to each other. The support shaft 6 penetrates one boss protrusion 2a provided on the bracket holder 2 and two boss protrusions 3a provided on the belt holder 3 so as to be rotatable relative to each other in the left-right direction. The boss protrusion 2a constitutes one longitudinal end of the bracket holder 2. In this embodiment, as shown in FIGS. 1 and 2, the boss protrusion 2a constitutes the upper end of the bracket holder 2 when the article holder 1A is suspended. The boss protrusion 3a also constitutes one longitudinal end of the belt holder 3. In this embodiment, as shown in FIGS. 1 and 2, the boss protrusion 3a also constitutes the upper end of the belt holder 3 when the article holder 1A is suspended.

[0043] 4, the bracket holder 2 is shown in a state where it is opened to the front side relative to the belt holder 3. Furthermore, in FIG.

[0044] As shown in Figures 4 and 5, when the bracket holder 2 is hanging the item holder 1A, it can be rotated relative to the belt holder 3 so as to open toward the front side relative to the belt holder 3, based on the support shaft 6 provided at the upper end of the item holder 1A.

[0045] Additionally, in the article holder 1A, the belt holder 3 is provided with a receiving portion 8 capable of receiving the bracket holder 2 therein.

[0046] In this embodiment, the storage section 8 is a step formed on the surface of the belt holder 3. In this embodiment, the storage section 8 is a step that is open on the top and both the left and right sides of the belt holder 3 when the article holder 1A is suspended. For example, as shown in FIG. 3 , according to the article holder 1A, the bracket holder 2 is exposed from the left and right sides of the storage section 8 even when it is stored in the storage section 8 formed in the belt holder 3. Therefore, even when the bracket holder 2 is stored in the storage section 8, the user can easily open and close the bracket holder 2 by holding the bracket holder 2 from the left and right sides of the storage section 8. Note that in this embodiment, the storage section 8 is provided on the surface of the front part 4.

[0047] In this embodiment, when the bracket holder 2 is opened relative to the belt holder 3, the opening angle of the bracket holder 2 can be fixed by an elastic member provided on either the bracket holder 2 or the belt holder 3, and a pressing protrusion provided on the other of the bracket holder 2 and the belt holder 3, which can be pressed by the elastic member.

[0048] Fig. 6 is an enlarged perspective view from the back side showing the relationship between the pressing protrusion provided on the bracket holder 2 and the elastic member provided on the belt holder 3. Fig. 6 shows only the front part 4 of the belt holder 3, with the back part 5 removed together with the support shaft 6. In this embodiment, as shown in Fig. 6, the boss protrusion 3a is a cylindrical boss protrusion formed with a shaft support hole h3 through which the support shaft 6 rotatably passes.

[0049] In this embodiment, the belt holder 3 includes a leaf spring 11 as an elastic member. Also, in this embodiment, the bracket holder 2 includes a pressing protrusion 12 that can press the leaf spring 11. The pressing protrusion 12 presses the leaf spring 11, thereby maintaining the bracket holder 2 in a closed position relative to the belt holder 3, while the pressing protrusion 12 overcomes the leaf spring 11 against the pressure of the leaf spring 11, thereby rotating the bracket holder 2 so as to open toward the front side relative to the belt holder 3.

[0050] In this embodiment, the pressing protrusion 12 is provided on the boss protrusion 2a. In this embodiment, the boss protrusion 2a is provided with two pressing protrusions 12 spaced apart in the width direction. Also, in this embodiment, the leaf spring 11 is disposed between the two boss protrusions 3a. The pressing protrusion 12 presses the pressing protrusion 12 in the length direction (up and down direction) when the bracket holder 2 is closed relative to the belt holder 3. As shown in FIG. 6 , with the article holder 1A suspended, the leaf spring 11 presses the pressing protrusion 12 upward when the bracket holder 2 is closed relative to the belt holder 3. As a result, the bracket holder 2 remains closed relative to the belt holder 3 until the pressing protrusion 12 overcomes the leaf spring 11 against the biasing force (elastic force) of the leaf spring 11.

[0051] 7 shows an enlarged view of the rear side of the bracket holder 2. In FIG. 7, only the bracket holder 2 is shown.

[0052] The pressing protrusion 12 has a first contact surface 12a that contacts the leaf spring 11 when the bracket holder 2 is closed relative to the belt holder 3, and a second contact surface 12b that contacts the leaf spring 11 when the bracket holder 2 is open to the front relative to the belt holder 3.

[0053] As shown in Fig. 7, the pressing protrusion 12 is disposed at a position below the rear side of the boss protrusion 2a. In this embodiment, the boss protrusion 2a is a cylindrical boss protrusion formed with a shaft support hole h2 through which the support shaft 6 rotatably passes, as shown in Fig. 7. The first contact surface 12a is oriented to face downward when the article holder 1A is suspended, as shown in Fig. 7. The second contact surface 12b is oriented to face the rear side when the article holder 1A is suspended, as shown in Fig. 7.

[0054] Fig. 8 shows an enlarged view of the back side of the front part 4 of the belt holder 3 together with the leaf spring 11. Fig. 9 shows an enlarged view of the front side of the front part 4 together with the leaf spring 11. However, in Figs. 8 and 9, the leaf spring 11 shown by the solid line is shown in a state where it is assembled between the bracket holder 2 and the front part 4 with the bracket holder 2 closed relative to the front part 4. Furthermore, Fig. 10 is a plan view showing the front part 4 from above. However, in Fig. 10, the leaf spring 11 has been removed.

[0055] Referring to FIG. 8 , in this embodiment, the leaf spring 11 is a flat leaf spring, as indicated by the dashed line. However, the leaf spring 11 is assembled between the bracket holder 2 and the front part 4 so that the leaf spring 11 is bent when the bracket holder 2 is closed relative to the front part 4. As indicated by the solid line in FIG. 8 , when the bracket holder 2 is assembled relative to the front part 4 in a closed state, the leaf spring 11 is an L-shaped leaf spring including a fixed portion 11a that is fixed to the front part 4, a pressing portion 11b that presses the pressing protrusion 12, and a bent portion 11c that is connected between the fixed portion 11a and the pressing portion 11b. In this embodiment, the bent portion 11c of the leaf spring 11 is formed by the pressing protrusion 12 provided on the bracket holder 2 pressing the leaf spring 11. However, the leaf spring 11 may be an L-shaped leaf spring in advance.

[0056] In this embodiment, the fixing portion 11a of the leaf spring 11 is fixed to a spring fixing portion 4c provided on the front part 4. As shown in FIG. 10, in this embodiment, the spring fixing portion 4c is a slit hole formed in the front part 4. The spring fixing portion 4c is disposed between two boss protrusions 3a. As shown in FIG. 8, the fixing portion 11a of the leaf spring 11 is fixed to the front part 4 by being inserted into the spring fixing portion 4c through an insertion port A41 formed in the front part 4. In this embodiment, a through hole A42 opening to the back surface of the front part 4 is formed in the spring fixing portion 4c. Similarly, as shown in FIG. 9, in this embodiment, a through hole A42 opening to the front surface of the front part 4 is also formed in the spring fixing portion 4c. That is, in this embodiment, the spring fixing portion 4c is open to the outside on both the front and back surfaces. Therefore, in this embodiment, the fixing portion 11a of the leaf spring 11 is exposed to the outside from the spring fixing portion 4c, i.e., the front part 4, through these through holes A42.

[0057] 11 shows an enlarged view of the relationship between the pressing protrusion 12 provided on the bracket holder 2 and the leaf spring 11 provided on the belt holder 3. FIG. 11 corresponds to FIG. 3, and shows the bracket holder 2 in a closed state relative to the belt holder 3.

[0058] 11, when the bracket holder 2 is closed relative to the belt holder 3 with the article holder 1A suspended, the pressing portion 11b of the leaf spring 11 provided on the belt holder 3 presses upward the first contact surface 12a of the pressing protrusion 12 provided on the boss protrusion 2a of the bracket holder 2 by the bending stress of the leaf spring 11, i.e., the restoring force (elastic force) of the leaf spring 11. Therefore, the bracket holder 2 is maintained in a closed state relative to the belt holder 3 as shown in FIG. 11 (FIG. 3) until the first contact surface 12a of the pressing protrusion 12 overcomes the pressing portion 11b of the leaf spring 11.

[0059] 12 shows the bracket holder 2 in an open state relative to the belt holder 3. Fig. 12 also shows a state in which first contact surface 12a of pressing protrusion 12 provided on boss protrusion 2a of bracket holder 2 has overcome pressing portion 11b of leaf spring 11 against the pressing force (elastic force) received from said pressing portion 11b. When article holder 1A is suspended, for example, a force toward the front side is applied to bracket holder 2, causing first contact surface 12a of pressing protrusion 12 to overcome pressing portion 11b of leaf spring 11 as shown in Fig. 12, and thereafter, bracket holder 2 can be freely opened toward the front side relative to belt holder 3. On the other hand, after the first contact surface 12a of the pressing protrusion 12 has overcome the pressing portion 11b of the leaf spring 11, the pressing portion 11b of the leaf spring 11 provided on the belt holder 3 can support the second contact surface 12b of the pressing protrusion 12 provided on the boss protrusion 2a of the bracket holder 2 at an angle facing upward on the front side. Therefore, after the first contact surface 12a of the pressing protrusion 12 has overcome the pressing portion 11b of the leaf spring 11, the bracket holder 2 is maintained in an open state with respect to the belt holder 3, as shown in Fig. 12 (Fig. 4).

[0060] FIG. 13 shows the bracket holder 2 in its most open state relative to the belt holder 3. As described above, after the first contact surface 12a of the pressing protrusion 12 overcomes the pressing portion 11b of the leaf spring 11, the bracket holder 2 can freely open toward the front side relative to the belt holder 3. However, the opening angle of the bracket holder 2 is limited by the contact of the back surface of the upper end of the bracket holder 2 with the upper end of the belt holder 3. In this embodiment, the back surface of the upper end of the bracket holder 2 is the back surface F21 of the upper end of the base 21. Also, in this embodiment, the upper end of the belt holder 3 is the upper end 5e of the rear part 5. For example, referring to FIG. 11, the upper end 5e of the rear part 5 is inclined downward as it approaches the rear side when the article holder 1A is suspended. This allows the bracket holder 2 to be opened to the maximum angle possible without interfering with the worker.

[0061] Incidentally, as a tool holder, one possible type is one in which the case body to which the tool is attached swings widthwise (left and right) relative to the belt holder, as in Patent Document 1, so that the tool does not interfere with the user's daily activities.

[0062] However, in the case of the sheath described in Patent Document 1, for example, when a user works with a blade tool attached to a waist belt, the blade tool swings along the direction in which the waist belt extends, i.e., the blade tool swings around the user's waist. In this case, the swinging blade tool blocks the user's movement, which can result in the blade tool getting in the way of the work. In addition, when working with multiple blade tools attached in the direction in which the belt extends, the swinging of at least one of the blade tools can cause adjacent tools to interfere with each other.

[0063] In contrast, with the item holder 1A, even if the user crouches down and an item (e.g., spirit level 100) attached to the item holder 1A comes into contact with the ground, the bracket holder 2 to which the item is attached opens by bending toward the front side relative to the belt holder 3, so that the item attached to the bracket holder 2 is less likely to interfere with the user's movements to get up or down. Furthermore, with the item holder 1A, the bracket holder 2 can be moved relative to the belt holder 3, so that external forces input through the bracket holder 2 can be released by the movement of the bracket holder 2. Therefore, the item holder 1A can prevent damage to the item holder 1A as a product.

[0064] In addition, with the article holder 1A, the bracket holder 2 to which the article is attached opens toward the front side relative to the belt holder 3, so that, for example, when the article holder 1A is attached to a user's waist belt, the article does not swing around the user's waist. Therefore, even when the bracket holder 2 and the article are opened relative to the belt holder 3, the article is less likely to obstruct the user's movement. Also, when working with multiple articles attached around the waist belt, the multiple articles are less likely to interfere with each other.

[0065] Therefore, the article holder 1A is easy to use and does not interfere with daily activities. Furthermore, the article holder 1A allows an article such as the spirit level 100 to be attached using a bracket 115. Therefore, unlike the sheath described in Patent Document 1, the article holder 1A does not require a case body to accommodate a long article. Therefore, unlike the sheath described in Patent Document 1, the article holder 1A does not increase in size in proportion to the size of the article to be accommodated in the case body.

[0066] Furthermore, the sheath described in Patent Document 1 may swing together with the sharp tool due to vibrations, for example, while walking. In this case, if the case tilts relative to the support, the sharp tool housed in the case may fall. In addition, the swinging of the case may make it difficult to insert the sharp tool into the case.

[0067] In contrast, with the article holder 1A, as shown in FIG. 11 , the bracket holder 2 is maintained in a closed position relative to the belt holder 3 by the pressing protrusion 12 provided on the bracket holder 2 pressing against the leaf spring 11 provided on the belt holder 3. Meanwhile, the pressing protrusion 12 overcomes the leaf spring 11 against the pressure of the leaf spring 11, causing the bracket holder 2 to rotate so as to open toward the front side relative to the belt holder 3. The article holder 1A can prevent the bracket holder 2 from opening unintentionally by the user. This can prevent tools and other articles from falling out due to the bracket holder 2 accidentally opening. Furthermore, in this case, the bracket holder 2 is maintained in a closed state, making it easy to attach tools and other articles.

[0068] In this embodiment, the article holder 1A can be used by opening the bracket holder 2 relative to the belt holder 3 in advance. Alternatively, the article holder 1A can be used by closing the bracket holder 2 relative to the belt holder 3 in advance.

[0069] In article holder 1A, leaf spring 11, which serves as an elastic member, can be provided on either bracket holder 2 or belt holder 3. Correspondingly, pressing protrusion 12 can be provided on the other of bracket holder 2 and belt holder 3. Therefore, leaf spring 11, which serves as an elastic member, can be provided on bracket holder 2, and pressing protrusion 12 can be provided on belt holder 3.

[0070] 11, when the bracket holder 2 is closed relative to the belt holder 3, the first contact surface 12a of the pressing protrusion 12 comes into contact with the pressing portion 11b of the leaf spring 11, thereby more reliably preventing the bracket holder 2 from opening unintentionally by the user. Also, when the bracket holder 2 is opened relative to the belt holder 3, the first contact surface 12a of the pressing protrusion 12 comes into contact with the pressing portion 11b of the leaf spring 11, thereby elastically maintaining the bracket holder 2 in an open state at a desired angle relative to the belt holder 3 even after the bracket holder 2 is opened.

[0071] Furthermore, according to the article holder 1A, the belt holder 3 is provided with two boss protrusions 3a spaced apart in the width direction for rotatably connecting the bracket holder 2, while the bracket holder 2 is provided with one boss protrusion 2a disposed between the two boss protrusions 3a for rotatably connecting the belt holder 3, and further, a pressing protrusion 12 is provided on one boss protrusion 2a, while a leaf spring 11 is disposed between the two boss protrusions 3a. In this case, the leaf spring 11 and the pressing protrusion 12 are efficiently housed inside the article holder 1A, thereby simplifying the external shape of the article holder 1A.

[0072] According to the article holder 1A, two boss protrusions are provided on the bracket holder 2 at a widthwise interval for rotatably connecting the belt holder 3, while one boss protrusion is provided on the belt holder 3 and is positioned between the two boss protrusions for rotatably connecting the bracket holder 2; furthermore, a pressing protrusion 12 is provided on the one boss protrusion 2a, while a leaf spring 11 can be positioned between the two boss protrusions 3a.

[0073] Claim 6 (Effect) Furthermore, the article holder 1A uses a leaf spring 11 as the elastic member. In this case, it is possible to compactly secure the space required for arranging the elastic member between the bracket holder 2 and the belt holder 3. Furthermore, the leaf spring can easily provide the biasing force (elastic force) required for the elastic member by simply assembling it between the bracket holder 2 and the belt holder 3 in a bent state.

[0074] Additionally, as shown in Fig. 1, for example, in the article holder 1A, the belt holder 3 has a storage section 8 capable of storing the bracket holder 2. In this case, when the bracket holder 2 is closed, the bracket holder 2 is efficiently stored in the storage section 8 of the belt holder 3, and the outer shape of the article holder 1A can be simplified so that the surface of the bracket holder 2 and the surface of the belt holder 3 form substantially the same surface, as shown in Fig. 1. Furthermore, storing the bracket holder 2 in the storage section 8 of the belt holder 3 allows the article holder 1A to be made compact.

[0075] Additionally, in the article holder 1A, the belt holder 3 has two parts, a front part 4 and a back part 5, which are rotatably connected so that one of the back part 5 and the front part 4 opens relative to the other of the back part 5 and the front part 4.

[0076] 1 and 2, the front part 4 has two boss protrusions 3a. Meanwhile, the rear part 5 has two boss flanges 5a spaced apart in the width direction for rotatably connecting the front part 4. In this embodiment, the boss flanges 5a have a plate shape formed by bending a portion of the rear part 5, and are provided with a shaft support hole (not shown) through which the support shaft 6 passes rotatably in the width direction (left-right direction).

[0077] In this embodiment, the front part 4 and the rear part 5 are connected by a support shaft 6 so as to be rotatable relative to each other. The support shaft 6 passes through a boss protrusion 3a provided on the front part 4 and a boss flange 5a provided on the rear part 5 in the left-right direction. The boss flange 5a forms one longitudinal end of the rear part 5. In this embodiment, the boss flange 5a forms the upper end of the rear part 5 when the article holder 1A is suspended, as shown in FIG. 1 or 2 . The two boss flanges 5a are each located widthwise outward of the boss protrusion 3a of the front part 4. In this embodiment, the support shaft 6 passes through the boss protrusions 3a and the two boss flanges 5a so as to be rotatable relative to each other in the left-right direction. As a result, the front part 4 and the rear part 5 are rotatably connected by the support shaft 6 so that one of the rear part 5 and the front part 4 opens relative to the other of the rear part 5 and the front part 4.

[0078] Additionally, in the article holder 1A, the belt holder 3 is provided with an opening prevention pin 7 that prevents one of the front part 4 and the rear part 5 from opening relative to the other of the front part 4 and the rear part 5.

[0079] In the belt holder 3, the front part 4 has two pin support protrusions 4b spaced apart in the width direction. The two pin support protrusions 4b each constitute the other longitudinal end of the front part 4. That is, the pin support protrusions 4b constitute the lower end of the front part 4 when the article holder 1A is suspended. In the belt holder 3, the rear part 5 has two pin support flanges 5b spaced apart in the width direction. The two pin support flanges 5b each constitute the other longitudinal end of the rear part 5. In this embodiment, as shown in FIGS. 1 and 2, the two pin support flanges 5b each constitute the lower end of the rear part 5 when the article holder 1A is suspended. The two pin support flanges 5b are each positioned outward in the width direction from the pin support protrusions 4b of the front part 4. In this embodiment, the opening prevention pin 7 penetrates in the left-right direction together with the pin support protrusions 4b and the pin support flanges 5b. As a result, the opening prevention pin 7 penetrates the pin support protrusion 4b and the pin support flange 5b, respectively, thereby preventing the front part 4 and the rear part 5 from opening relative to each other with the support shaft 6 as the base point.

[0080] However, in this embodiment, the stop pin 7 includes a head 7a and a nut 7b. As shown in FIG. 1 , the nut 7b is removably threaded onto one end of the stop pin 7. The nut 7b holds the stop pin 7 against the pin support flange 5b of the rear part 5 to prevent it from falling out from the left side. In addition, as shown in FIG. 2 , the stop pin 7 includes a head 7a at the other end of the stop pin 7. The head 7a holds the stop pin 7 against the pin support flange 5b of the rear part 5 to prevent it from falling out from the right side. Therefore, in this embodiment, the stop pin 7 is inserted through the pin support protrusion 4b and the pin support flange 5b, respectively, and then the nut 7b is attached, thereby reliably fixing the front part 4 and the rear part 5 in a closed state. Meanwhile, in this embodiment, the stop pin 7 can be removed from the left side by removing the nut 7b. By pulling out the opening prevention pin 7, the front part 4 and the rear part 5 can be opened relative to each other with the support shaft 6 as the base point.

[0081] Fig. 14 shows the article holder 1A with the opening prevention pin 7 removed. Fig. 15 shows the state in which the rear part 5 is opened from the front part 4 to the rear side. Fig. 16 shows the state in which the rear part 5 is opened from the front part 4 to the rear side.

[0082] As shown in Fig. 14, after removing the stop pin 7, the belt holder 3 can be easily positioned between the rear part 5 and the front part 4 by opening the rear part 5 backward relative to the front part 4, for example, as shown in Fig. 15 or 16. Then, after closing the rear part 5 backward relative to the front part 4 again, as shown in Fig. 14, the stop pin 7 is inserted and the nut 7b is attached, thereby attaching the belt to the belt holder 3. This allows the user to easily attach the article holder 1A to the belt even while wearing the belt.

[0083] That is, according to the article holder 1A, the belt holder 3 is configured as two parts that can be opened and closed, so that the article holder 1A can be easily attached to the belt.

[0084] Additionally, the belt holder 3 uses the stop pin 7 to prevent the front part 4 or the back part 5 from accidentally opening. Therefore, according to this embodiment, an article equipped with a bracket 115 can be stably carried via the article holder 1A. Furthermore, in this embodiment, the stop pin 7 includes a head 7a and a nut 7b, and the nut 7b is detachable from the stop pin 7. In this case, the stop pin 7 uses existing mechanical elements, namely a screw shaft with a head and a nut that can be screwed onto the screw shaft, thereby reducing the manufacturing costs of the article holder 1A.

[0085] Furthermore, the front part 4 and the rear part 5 are rotatably connected together with the bracket holder 2. In this embodiment, the front part 4 and the rear part 5 are rotatably connected together with the bracket holder 2 by a support shaft 6. In this case, the front part 4 and the rear part 5 are rotatably connected together with the bracket holder 2 by the support shaft 6 that is shared with the bracket holder 2, which allows the external shape of the article holder 1A to be simplified, for example, as shown in FIG. 14 . Furthermore, by sharing the support shaft 6, the article holder 1A can be made compact.

[0086] Next, Fig. 17 shows an article holder 1B according to a second embodiment of the present invention from the front side. Fig. 18 shows the article holder 1B from the left side. However, in Fig. 18, the bracket holder 2 is shown in a state closed relative to the belt holder 3. In Fig. 19, the bracket holder 2 is shown in an open state relative to the belt holder 3. Furthermore, in Fig. 20, the bracket holder 2 is shown in its most open state relative to the belt holder 3.

[0087] In the article holder 1B, similarly to the article holder 1A, the bracket holder 2 is rotatably connected to the belt holder 3 by a support shaft 6 so as to open toward the front side relative to the belt holder 3.

[0088] As shown in Fig. 18, in the article holder 1B, the bracket holder 2 includes a linear member 14. Furthermore, referring to Fig. 19, in the article holder 1B, the belt holder 3 includes a locking protrusion 15 that can lock the linear member 14. As shown in Fig. 18, the bracket holder 2 is maintained in a closed position relative to the belt holder 3 when the linear member 14 is locked by the locking protrusion 15. On the other hand, as shown in Fig. 19 or 20, when the linear member 14 is released from the locking protrusion 15, the bracket holder 2 rotates to open toward the front side relative to the belt holder 3.

[0089] Fig. 21 shows the back side of the bracket holder 2 of the article holder 1B in a partially disassembled state. Fig. 22 shows the front side of the bracket holder 2 of the article holder 1B in a partially disassembled state. Furthermore, Fig. 23 shows the front part 4 of the belt holder 3 of the article holder 1B from the front side.

[0090] As shown in FIG. 21 , in the article holder 1B, the linear member 14 is provided on the back surface of the bracket holder 2. In this embodiment, as shown in FIG. 21 , the linear member 14 is provided at the lower end of the back surface of the bracket holder 2 when the bracket holder 2 (article holder 1B) is suspended. Specifically, the linear member 14 is provided at the lower end of the back surface of the base 21 of the bracket holder 2. In this embodiment, a widthwise groove 28 extending in the width direction (left and right direction) is provided at the lower end of the base 21. In this embodiment, the linear member 14 is housed in the widthwise groove 28.

[0091] Furthermore, as shown in FIG. 22, in the article holder 1B, the linear member 14 is a ring-shaped linear member wound around the back surface of the bracket holder 2. In this embodiment, the linear member 14 is an elastic member. A specific example of the linear member 14 is an O-ring. In this embodiment, the base 21, i.e., the bracket holder 2, has a notch 2c formed at the lower end of the bracket holder 2 when the bracket holder 2 (article holder 1B) is suspended, as shown in FIG. 22. This allows the linear member 14 to deform freely in the thickness direction (front-to-back direction) at the portion of the notch 2c. In this embodiment, the widthwise groove 28 is provided as an annular groove extending circumferentially around the lengthwise direction (up-down direction).

[0092] As shown in FIG. 23, in the article holder 1B, the locking protrusion 15 is provided in the storage section 8 of the belt holder 3. In this embodiment, as shown in FIG. 23, the storage section 8 is provided with a base portion 15a extending upward from a shelf surface 8a of the storage section 8 when the belt holder 3 (article holder 1B) is suspended. In this embodiment, as shown in FIG. 23, the locking protrusion 15 extends further upward from the base portion 15a when the belt holder 3 (article holder 1B) is suspended. In addition, a wall surface 8b extending in the length direction (upward) from the shelf surface 8a of the storage section 8 is provided with a groove portion 8c extending in the width direction (left-right direction). The groove portion 8c can accommodate the linear member 14 when the bracket holder 2 is closed. Furthermore, in this embodiment, a through window A4 is provided in the groove portion 8c on the back side of the locking protrusion 15. This allows the linear member 14 to be easily hooked onto the back side of the locking projection 15.

[0093] Fig. 24 shows an enlarged cross section of the upper end portion of the article holder 1B. Fig. 24 corresponds to Fig. 18, and in Fig. 24, the bracket holder 2 is shown in a state where it is closed relative to the belt holder 3.

[0094] In the article holder 1B, one of the bracket holder 2 and the belt holder 3 can be provided with an elongated hole 16, and the other of the bracket holder 2 and the belt holder 3 can be provided with a protrusion 17 that is accommodated in the elongated hole 16 and can move along the elongated hole 16. This allows the bracket holder 2 and the belt holder 3 to move relatively in accordance with the relative movement of the elongated hole 16 and the protrusion 17 so that the linear member 14 is locked by the locking protrusion 15 while the linear member 14 is released from the locking by the locking protrusion 15.

[0095] In this embodiment, the bracket holder 2 has an elongated hole 16. In the article holder 1B, the belt holder 3 has a protrusion 17 that is accommodated in the elongated hole 16 and is movable along the elongated hole 16.

[0096] As shown in FIG. 24, the elongated hole 16 and the protrusion 17 are provided at the upper end of the article holder 1B. In this embodiment, the elongated hole 16 is a shaft support hole h2 provided in the boss protrusion 2a. That is, in this embodiment, the elongated hole 16 is provided in the boss protrusion 2a. The elongated hole 16 extends in the length direction. That is, in this embodiment, the elongated hole 16 is a shaft support hole h2 that extends in the up-down direction when the article holder 1B is suspended as shown in FIG. 24. In contrast, in this embodiment, the protrusion 17 is the support shaft 6. As shown in FIG. 24, when the article holder 1B is suspended and the bracket holder 2 is closed, the support shaft 6 contacts the upper end of the shaft support hole h2.

[0097] Fig. 25 shows an enlarged cross section of the lower end of the article holder 1B. Fig. 25 also corresponds to Fig. 18, and in Fig. 25, the bracket holder 2 is shown in a closed state relative to the belt holder 3.

[0098] As shown in Fig. 25, the linear member 14 and the locking protrusion 15 are provided at the lower end of the article holder 1B. As shown in Fig. 25, when the article holder 1B is suspended and the bracket holder 2 is closed, the linear member 14 is caught on the back side of the locking protrusion 15 and thereby locked to the locking protrusion 15. This prevents the bracket holder 2 from opening to the front side relative to the belt holder 3.

[0099] Figure 26 also shows an enlarged cross-section of the upper end of the article holder 1B. However, in Figure 26, the bracket holder 2 is shown in a state raised relative to the belt holder 3. Figure 27 also shows an enlarged cross-section of the lower end of the article holder 1B. However, in Figure 26, the bracket holder 2 is also shown in a state raised relative to the belt holder 3.

[0100] In this embodiment, since the shaft support hole h2 is an elongated hole, when the article holder 1B is suspended, the bracket holder 2 can slide upward along the shaft support hole h2 relative to the belt holder 3, as shown in FIG. 26. The bracket holder 2 can be pulled up until the lower end of the shaft support hole h2 provided in the bracket holder 2 comes into contact with the support shaft 6 held by the belt holder 3, as shown in FIG. 26. Meanwhile, at the lower end of the article holder 1B, when the bracket holder 2 is pulled up relative to the belt holder 3, the linear member 14 is released from engagement with the locking protrusion 15, as shown in FIG. 27. In this embodiment, the back surface of the locking protrusion 15 has an inclined surface 15b that slopes upward toward the front side when the article holder 1B is suspended, as shown in FIG. 27. As a result, in this embodiment, the linear member 14 can be released from engagement with the locking protrusion 15 without having to pull the bracket holder 2 up relative to the belt holder 3 until it completely exceeds the upper end of the locking protrusion 15. However, the shaft support hole h2 may be an elongated hole that allows the linear member 14 to be pulled up until it completely exceeds the upper end of the locking projection 15.

[0101] According to the article holder 1B, the bracket holder 2 can be opened to the front side relative to the belt holder 3, using the support shaft 6 as a base point, by releasing the engagement between the linear member 14 and the engagement protrusion 15, similar to the article holder 1A.

[0102] Figure 28 also shows an enlarged cross-section of the article holder 1B. Figure 28 corresponds to Figure 19, and in this Figure, the bracket holder 2 is shown in an open state relative to the belt holder 3. Furthermore, Figure 29 also shows an enlarged cross-section of the article holder 1B. Figure 29 also corresponds to Figure 19, and in this Figure, the bracket holder 2 is shown in an open state relative to the belt holder 3, similar to Figure 28.

[0103] According to the article holder 1B, when the article holder 1B is suspended, the bracket holder 2 is in a state where it is closed relative to the belt holder 3 and pressed downward along the shaft support hole h2, as shown in FIG. 24. In this case, as shown in FIG. 25, the linear member 14 provided on the bracket holder 2 is engaged with the engaging protrusion 15 provided on the belt holder 3. This maintains the bracket holder 2 in a closed position relative to the belt holder 3. On the other hand, when the article holder 1B is suspended, as shown in FIG. 26, if the bracket holder 2 is pulled upward relative to the belt holder 3 along the shaft support hole h2, the engaged state between the linear member 14 and the engaging protrusion 15 can be released, as shown in FIG. 27. Next, when the bracket holder 2 is rotated toward the front side relative to the belt holder 3 with the support shaft 6 in contact with the lower end of the shaft support hole h2, as shown in FIG. 28, the bracket holder 2 can be opened toward the front side relative to the belt holder 3, as shown in FIG. 29. As a result, like article holder 1A, article holder 1B can prevent tools and other articles from falling, which can occur when bracket holder 2 is accidentally opened. Also, in this case, like article holder 1A, bracket holder 2 is maintained in a closed state, making it easy to attach tools and other articles.

[0104] In this embodiment, like the article holder 1A, the article holder 1B can be used by opening the bracket holder 2 relative to the belt holder 3 in advance. Alternatively, the article holder 1B can be used by closing the bracket holder 2 relative to the belt holder 3 in advance.

[0105] Furthermore, according to the article holder 1B, the bracket holder 2 and the belt holder 3 move relative to each other in response to the relative movement of the elongated hole 16 and the protrusion 17, such that the linear member 14 is locked by the locking protrusion 15 while the linear member 14 is released from the locking protrusion 15. In this case, the simple mechanism of the elongated hole 16 and the protrusion 17 movably received in the elongated hole 16 can guide and limit the sliding of the bracket holder 2 relative to the belt holder 3. In particular, according to this embodiment, the shaft support hole h2 provided in the bracket holder 2 is the elongated hole 16, while the support shaft 6 rotatably connecting the bracket holder 2 and the belt holder 3 is the protrusion 17, thereby simplifying the external shape of the article holder 1B. Furthermore, the support shaft 6 serving as the protrusion 17 is received in the shaft support hole h2 formed in the boss protrusion 2a serving as the elongated hole 16, thereby enabling the article holder 1B to be made compact.

[0106] Furthermore, a linear member 14 having two separated ends and a straight line shape can be used as the linear member 14. In this case, the linear member 14 can be attached to the bracket holder 2 by fixing each of the ends of the linear member 14 to the bracket holder 2. In contrast, in this embodiment, the linear member 14 is an annular linear member. In this case, for example, as in this embodiment, the linear member 14 can be easily attached to the bracket holder 2 by the simple operation of simply accommodating the linear member 14 in a groove 28 provided in the bracket holder 2.

[0107] The linear member 14 can be made of metal (for example, wire) or resin (including rubber). However, the linear member 14 is preferably an elastic member. In this embodiment, the linear member 14 is an O-ring. In this case, the manufacturing cost of the article holder 1B can be reduced.

[0108] FIG. 30 schematically illustrates an article holder 1C according to a third embodiment of the present invention, with the cover 22 removed, together with a bracket 115 attached to a tool. The article holder 1C is similar to the bracket holder 2 of the article holder 1A and the article holder 1B, except that the stopper member 23 is replaced with a stopper member 230. Note that the bracket 115 is a rectangular bracket instead of the circular bracket 115 of the article holder 1A and the article holder 1B. In this embodiment, the bracket holder 2 is equipped with a foolproof (childproof) mechanism that prevents the bracket 115 attached to the bracket holder 2 from being easily removed. The foolproof mechanism according to this embodiment is a foolproof mechanism that prevents the stopper member 230 from being easily operated.

[0109] The foolproof mechanism according to this embodiment is provided in the stopper 230. The stopper member 230 includes a main body 231 for opening and closing the attachment opening A24, and an operating part 232 for operating the main body 231. As shown in FIG. 30, with the article holder 1A suspended, the stopper member 230 opens the attachment opening A24 by moving it diagonally downward to the left as indicated by arrow F3, and closes the attachment opening A24 by moving it diagonally upward to the left as indicated by arrow F1. FIG. 30 shows the attachment opening A24 in a closed state.

[0110] In the stopper member 230, the main body portion 231 is slidably held relative to the base 21. In this embodiment, the main body portion 231 can slide diagonally left relative to the base 21. A holding plate 231a that slidably holds the operation portion 232 is provided on the back surface of the main body portion 231. The operation portion 232 can slide diagonally left relative to the surface of the holding plate 231a provided on the main body portion 231. The operation portion 232 can also slide diagonally right relative to the surface of the holding plate 231a provided on the main body portion 231. The main body portion 231 and the operation portion 232 are provided with meshing portions 231c and 232c that mesh with each other, respectively. In this embodiment, the meshing portion 231c is provided on the side facing the operation portion 232. In this embodiment, the meshing portion 232c is provided on the side facing the main body portion 231. In this embodiment, the interlocking portion 231c provided on the main body portion 231 and the interlocking portion 232c provided on the operating portion 232 can be interlocked by bringing the operating portion 232 closer to the main body portion 231 at an angle to the right, and then bringing the operating portion 232 closer to the main body portion 231 at an angle to the left.

[0111] The inside of the stopper member 230 can be operated, for example, as follows.

[0112] 30 , first, as indicated by an arrow F1, the operation unit 232 is slid diagonally upward and left relative to the main body unit 231, thereby aligning the meshing portion 232c of the operation unit 232 with the meshing portion 231c of the main body unit 231 so that the meshing portion 232c of the operation unit 232 meshes with the meshing portion 231c of the main body unit 231. Next, as indicated by an arrow F2, the operation unit 232 is slid diagonally downward and right, thereby aligning the meshing portion 232c of the operation unit 232 with the meshing portion 231c of the main body unit 231 diagonally left. Thereafter, by sliding the operation unit 232 diagonally downward and left, the meshing portion 232c of the operation unit 232 meshes with the meshing portion 231c of the main body unit 231, and the main body unit 231 can be slid diagonally downward and left together with the operation unit 232. In this way, the stopper member 230 can open the attachment opening A24 only after a complicated operation. In this way, the stopper member 230 can exert a foolproof function that prevents the stopper member 230 from being easily operated. That is, in this embodiment, the foolproof mechanism is constituted by the stopper member 230 that includes a main body portion 231 and an operating portion 232, and in which the main body portion 231 and the operating portion 232 are provided with meshing portions (231c, 232c), respectively.

[0113] In addition, by operating the operating portion 232, the stopper member 230 can be automatically returned to the initial state shown in FIG. 30 by the elastic member after opening the attachment opening A24.

[0114] FIG. 31 shows a schematic diagram of a concrete example of a foolproof mechanism.

[0115] In the example of FIG. 31 , a coil spring 236 is provided between the main body 231 and the bracket holder 2. In this example, one end of the coil spring 236 is attached to the base 21 of the bracket holder 2. The other end of the coil spring 236 is attached to the main body 231. Additionally, in this example, the coil spring 236 is assembled so as to bias the main body 231 diagonally upward and to the left relative to the base 21. Furthermore, in this example, as shown in FIG. 31 , the main body 231 is provided with a stopper protrusion 231b protruding from a lower portion of the main body 231. As shown in FIG. 30 , the biasing force (elastic force) of the coil spring 236 causes the stopper protrusion 231b to come into contact with a stopper wall 29 provided on the base 21, thereby restricting movement of the stopper protrusion 231b diagonally upward and to the left relative to the base 21. Additionally, in the example of FIG. 31 , a coil spring 234 is provided between the operation unit 232 and the main body 231. In this example, one end of the coil spring 234 is attached to a holding plate 231a provided on the main body 231. The other end of the coil spring 234 is attached to the operating unit 232. In addition, in this example, the coil spring 234 is assembled so as to bias the operating unit 232 diagonally downward and to the left with respect to the main body 231. Furthermore, in the example of FIG. 31 , the operating unit 232 is provided with a coil spring 235 between it and the main body 231. In this example, one end of the coil spring 235 is also attached to a holding plate 231a provided on the main body 231. The other end of the coil spring 235 is attached to the operating unit 232. In addition, in this example, the coil spring 234 is assembled so as to bias the operating unit 232 diagonally upward and to the right with respect to the main body 231 by the biasing force (elastic force) of the coil spring 235.

[0116] In the example of FIG. 31 , operating unit 232 can slide diagonally upward and to the left relative to main body 231 against the biasing force (elastic force) of coil spring 234. Operating unit 232 can also slide diagonally downward and to the right relative to main body 231 against the biasing force (elastic force) of coil spring 235. Operating unit 232 can also slide diagonally downward and to the left relative to main body 231 against the biasing force (elastic force) of coil spring 236. At this time, operating unit 232 engages with main body 231. This allows main body 231 to slide diagonally downward and to the left together with operating unit 232. Thus, in the example of FIG. 31 , the use of a coil spring can make stopper member 230 more difficult to operate. Furthermore, after the operation using operating unit 232 is released, the restoring forces (elastic forces) of coil springs 236, 235, and 234 can automatically return the stopper member 230 to the initial state of FIG. 30 . That is, in this example, the foolproof mechanism is configured to be a more functional foolproof mechanism by including elastic members (coil springs 234 to 236) in addition to the main body portion 231 and the operating portion 232.

[0117] Another embodiment of the foolproof mechanism is shown diagrammatically in FIG.

[0118] In the example of FIG. 32, an elastic deformation portion 237 provided on the operating portion 232 is used instead of the coil spring 235. The elastic deformation portion 237 is a connecting portion that connects the operating portion 232 to a slide piece 238 that is slidable along the main body portion 231. The elastic deformation portion 237, together with the slide piece 238, is disposed diagonally downward and to the left of the meshing portion 231c. The elastic deformation portion 237 can be moved diagonally downward and to the right relative to the main body portion 231 against the biasing force (elastic force) of the elastic deformation portion 237 by pressing the operating portion 232 diagonally downward and to the right. In this case, the stopper member 230 can be operated in the same manner as in the example of FIG. 31. That is, as in this example, by providing the elastic deformation portion 237 on at least one of the main body portion 231 and the operating portion 232, the foolproof mechanism can be simplified in configuration by omitting some of the elastic members (e.g., the coil spring 235).

[0119] Another embodiment of the foolproof mechanism is shown diagrammatically in FIG.

[0120] 33 uses a torsion spring 239 provided in the operating portion 232 instead of the coil spring 234. In the example of FIG. 33, the torsion spring 239 is provided between the operating portion 232 and the main body portion 231. In this example, one end of the torsion spring 239 is also attached to a holding plate 231a provided in the main body portion 231. The other end of the torsion spring 239 is attached to the operating portion 232. In addition, in this example, the torsion spring 239 is assembled so that the biasing force (elastic force) of the torsion spring 239 biases the operating portion 232 diagonally downward to the left with respect to the main body portion 231. In this case, the stopper member 230 can be operated in the same manner as in the example of FIG. 31 or 32. That is, as in this example, by replacing part of the elastic member (e.g., coil spring 234) with a torsion spring, the foolproof mechanism can be made into a foolproof mechanism that requires a more complex operation, in which a rotational operation is added to the operation of stopper member 230.

[0121] Fig. 34 schematically shows another example of the bracket holder 2 of the article holder 1D according to the fourth embodiment of the present invention. The bracket holder 2 in Fig. 34 shows another example of a foolproof mechanism that prevents the stopper member 23 from being easily operated.

[0122] In FIG. 34 , the stopper member 23 is restricted from being pushed diagonally downward to the left by a rotating member 51 serving as an auxiliary stopper member. In this embodiment, the rotating member 51 is disposed between the base 21 and the cover 22. The rotating member 51 is rotatably connected to the base 21 by a support pin 51 a. In FIG. 34 , the stopper member 23 is prevented from being pushed diagonally downward to the left by the rotating member 51. To operate the stopper member 23, for example, the rotating member 51 is rotated in the direction of the arrow. This moves the rotating member 51 to the position shown by the dashed line. This allows the stopper member 23 to be pushed diagonally downward to the left. In other words, in this embodiment, by using the rotating member 51 rotatably connected to the base 21 by the support pin 51 a, the foolproof mechanism can be configured to require more complex operations, including the operation of the rotating member 51 (auxiliary stopper member) separate from the stopper member 230, in addition to the operation of the stopper member 230.

[0123] Fig. 35 schematically shows yet another example of the bracket holder 2 of the article holder 1E according to the fifth embodiment of the present invention. The bracket holder 2 in Fig. 34 shows yet another example of a foolproof mechanism that prevents the stopper member 23 from being easily operated.

[0124] In FIG. 35 , the stopper member 23 is restricted from being pushed diagonally downward to the left by a slide member 52 serving as an auxiliary stopper member. In this embodiment, the slide member 52 is disposed between the base 21 and the cover 22. The slide member 52 is held between the base 21 and the cover 22 so as to be slidable in the width direction (left-right direction). In FIG. 35 , the stopper member 23 is prevented from being pushed diagonally downward to the left by the slide member 52. To operate the stopper member 23, for example, the slide member 52 is slid in the direction of the arrow. This moves the slide member 52 to the position shown by the dashed line. This allows the stopper member 23 to be pushed diagonally downward to the left. That is, in this embodiment, by using the slide member 52 slidably held relative to the bracket holder 2, the foolproof mechanism can be configured to require a more complex operation, in which operation of the slide member 52 (auxiliary stopper member) separate from the stopper member 23 is added in addition to operation of the stopper member 23.

[0125] Figure 36 is a perspective view equivalent to Figure 22 showing a modified example of the article holder 1B of Figure 17, which is provided with an example of a foolproof mechanism that prevents the bracket from being easily operated, among the foolproof mechanisms that prevent the bracket attached to the bracket holder 2 from being easily removed. In Figure 36, the cover 22 is shown by a dashed line.

[0126] As shown in FIG. 36 , the bracket holder 2 includes a swinging member 53 serving as an auxiliary locking member. The swinging member 53 is a seesaw-type auxiliary stopper member that is held so as to be swingable in the front-to-back direction relative to the base 21. The swinging member 53 is disposed in front of the mounting opening A24 (above the mounting opening A24). In this embodiment, a through-hole 54 is formed in the base 21 on the front side of the mounting opening A24. The swinging member 53 is swingably housed in the through-hole 54. The swinging member 53 is swingably connected to the base 21 behind the guide surface F2. The rotation axis (swing center axis) of the swinging member 53 extends in the width direction. For example, the rotation axis can be located closer to one longitudinal end (upper end) 53b of the swinging member 53 than to the other longitudinal end (lower end) 53a of the swinging member 53.

[0127] 36, when the upper end 53b of the swinging member 53 is pushed inward, it sinks inward beyond the through-hole 54 (guide surface F2). On the other hand, when the upper end 53b of the swinging member 53 is pushed inward, it can protrude outward beyond the through-hole 54 (guide surface F2).

[0128] In contrast, when the lower end 53a of the oscillating member 53 is pushed in toward the back, the upper end 53b of the oscillating member 53 moves toward the front, so that the surface 53f of the oscillating member 53 forms the same plane as the guide surface F2 of the base 21, or the lower end 53a of the oscillating member 53, together with the upper end 53b of the oscillating member 53, can be sunk to a position behind the guide surface F2 of the base 21.

[0129] 36 , when the bracket 115 provided on the level 100 is set on the mounting portion 24, if the upper end 53b of the swinging member 53 is pushed back, the lower end 53a of the swinging member 53 will protrude further toward the front than the guide surface F2, and so when the level 100 is pulled out of the bracket holder 2, for example, the bracket 115 will abut against the lower end 53a of the swinging member 53. Therefore, when the bracket 115 provided on the level 100 is set on the mounting portion 24, if the upper end 53b of the swinging member 53 is pushed back, the bracket 115 cannot be removed from the mounting portion 24 by simply operating the stopper member 23. In contrast, if the lower end 53a of the swinging member 53 is pushed backward, the surface 53f of the swinging member 53 forms the same plane as the guide surface F2 of the base 21 or is positioned behind the guide surface F2 of the base 21, so that the bracket 115 can be removed from the mounting portion 24 simply by operating the stopper member 23. That is, in this embodiment, the foolproof mechanism is configured by the swinging member 53 that is swingably connected to the base 21. In other words, in this embodiment, by using the swinging member 53 that can swing relative to the base 21, the foolproof mechanism can be a foolproof mechanism that requires more complicated operations, such as operating the swinging member 53 (auxiliary stopper member) different from the stopper member 23 in addition to operating the stopper member 23. Note that, according to this embodiment, when setting the bracket 115 on the mounting portion 24, the bracket 115 can be easily set on the mounting portion 24 by pushing the lower end 53a of the swinging member 53 backward.

[0130] 37 is a plan view schematically showing another example of the bracket holder 2 of the article holder 1F according to the sixth embodiment of the present invention. In this embodiment, the bracket holder 2 is provided with another example of a foolproof mechanism that prevents the bracket attached to the bracket holder 2 from being easily removed, and that prevents the bracket from being easily operated.

[0131] As shown in FIG. 37, the bracket holder 2 includes a drawer member 55 serving as an auxiliary locking member. The drawer member 55 is held slidably in the front-to-back direction relative to the base 21. The drawer member 55 is disposed in front of the mounting opening A24 (above the mounting opening A24). In this embodiment, a guide hole 56 is formed in the base 21 on the front side of the mounting opening A24. The drawer member 55 is disposed inside the guide hole 56 so as to be slidable in the front-to-back direction (thickness direction). The drawer member 55 can be pulled out from the guide hole 56 to the front side of a guide surface F2 and can also be pushed into the guide hole 56 toward the same side as the guide surface F2 or toward the back side of the guide surface F2. In this embodiment, the drawer member 55 is disposed inside the guide hole 56 so as to form a gap S1 at one longitudinal end (upper end) of the guide hole 56, as shown in FIG. 37. For example, a user's finger can be inserted into the gap S1.

[0132] The drawer member 55 can be pulled out from the guide hole 56 to the front side of the guide surface F2 by inserting a finger into the gap S1 formed between the drawer member 55 and the guide surface F2. On the other hand, when the surface 55f of the drawer member 55 is pushed backward, the surface 55f of the drawer member 55 forms the same plane as the guide surface F2 of the base 21, or can be sunk until it is positioned behind the guide surface F2 of the base 21.

[0133] According to this embodiment, when the drawer member 55 is pulled outward while the bracket 115 is set in the mounting portion 24, the surface 55f of the drawer member 55 protrudes further outward than the guide surface F2. For example, when the level 100 is pulled out of the bracket holder 2, the bracket 115 abuts against the lower end 55a of the swinging member 55. Therefore, when the bracket 115 provided on the level 100 is set in the mounting portion 24 and the drawer member 55 is pulled outward, the bracket 115 cannot be removed from the mounting portion 24 by simply operating the stopper member 23. In contrast, when the drawer member 55 is pushed inward, the surface 55f of the drawer member 55 forms the same plane as the guide surface F2 of the base 21 or is positioned further back than the guide surface F2 of the base 21. This allows the bracket 115 to be removed from the mounting portion 24 by simply operating the stopper member 23. That is, in this embodiment, the foolproof mechanism is constituted by the drawer member 55 held slidably relative to the base 21. In other words, in this embodiment, by using the drawer member 55 slidable relative to the base 21, the foolproof mechanism can be made to be a foolproof mechanism that requires more complicated operations, in which operation of the drawer member 55 (auxiliary stopper member) different from the stopper member 23 is added in addition to operation of the stopper member 23. Note that, according to this embodiment, when setting the bracket 115 to the mounting portion 24, the bracket 115 can be easily set to the mounting portion 24 by pushing the drawer member 55 to the back side.

[0134] 38 is a plan view schematically showing another example of the bracket holder 2 of the article holder 1G according to the seventh embodiment of the present invention. In this embodiment, the bracket holder 2 is provided with yet another example of a foolproof mechanism that prevents the bracket attached to the bracket holder 2 from being easily removed, and that prevents the bracket from being easily operated.

[0135] This embodiment is a modified example of the foolproof mechanism of the article holder 1F. In this embodiment, too, the drawer member 55 is arranged inside the guide hole 56 so as to be slidable in the front-to-back direction. The drawer member 55 can be pulled out from the guide hole 56 to the front side of the guide surface F2, and can also be pushed into the guide hole 56 to the same position as the guide surface F2 or to the back side of the guide surface F2. However, in this embodiment, the drawer member 55 is arranged inside the guide hole 56 so as to form a gap S2 in the width direction (left-to-right direction) of the guide hole 56, as shown in FIG. 38 . For example, the user's fingers can be inserted into each of the two gaps S2.

[0136] The drawer member 55 can also be pulled out from the guide hole 56 to the front side of the guide surface F2 by inserting a finger into the gap S2 formed between the drawer member 55 and the guide surface F2. On the other hand, when the surface 55f of the drawer member 55 is pushed backward, the surface 55f of the drawer member 55 forms the same plane as the guide surface F2 of the base 21, or can be sunk until it is positioned behind the guide surface F2 of the base 21.

[0137] Note that Figure 38 shows the back side of the drawer member 55 removed from the base 21. In this embodiment, as shown in Figure 38, a plurality of guide protrusions 55a are provided on the back side of the drawer member 55. This allows the drawer member 55 to slide in the thickness direction (front-to-back direction) relative to the base 21 along the guide protrusions 55a. A plurality of guide protrusions (not shown) are also provided on the back side of the drawer member 55 in Figure 37. This allows the drawer member 55 in Figure 37 to also slide in the thickness direction (front-to-back direction) relative to the base 21 along the guide protrusions.

[0138] According to this embodiment, when the drawer member 55 is pulled outward while the bracket 115 is set in the mounting portion 24, the surface 55f of the drawer member 55 protrudes further outward than the guide surface F2. For example, when the level 100 is pulled out of the bracket holder 2, the bracket 115 abuts against the lower end 55a of the swinging member 55. Therefore, when the bracket 115 provided on the level 100 is set in the mounting portion 24 and the drawer member 55 is pulled outward, the bracket 115 cannot be removed from the mounting portion 24 by simply operating the stopper member 23. In contrast, when the drawer member 55 is pushed inward, the surface 55f of the drawer member 55 forms the same plane as the guide surface F2 of the base 21 or is positioned further back than the guide surface F2 of the base 21. This allows the bracket 115 to be removed from the mounting portion 24 by simply operating the stopper member 23. That is, in this embodiment, the foolproof mechanism is constituted by the drawer member 55 held slidably relative to the base 21. In other words, in this embodiment, by using the drawer member 55 slidable relative to the base 21, the foolproof mechanism can be made to be a foolproof mechanism that requires more complicated operations, in which operation of the drawer member 55 (auxiliary stopper member) different from the stopper member 23 is added in addition to operation of the stopper member 23. Note that, according to this embodiment, when setting the bracket 115 to the mounting portion 24, the bracket 115 can be easily set to the mounting portion 24 by pushing the drawer member 55 to the back side.

[0139] The above describes exemplary embodiments of the present invention, and various modifications can be made without departing from the scope of the claims. For example, the article holder may be any article that corresponds to the mounting portion 24 of the bracket holder 2, and the article attached to the article holder is not limited to tools. As described above, the belt holder 3 is preferably open in both the left and right directions, but it can be closed in either the left or right direction. Furthermore, although the stopper member 23 is disposed on the left side of the base 21, it may also be disposed on the right side of the base 21. Furthermore, the foolproof mechanism shown in FIGS. 30 to 38 is not limited to the article holder of the present invention and can be applied to an article holder in which the bracket holder 2 is integrated with the belt holder 3. In other words, the foolproof mechanism shown in FIGS. 30 to 38 can be applied to various article holders as long as they have a mounting portion 24 to which a bracket attached to an article can be detachably attached. Furthermore, in the article holder 1A, the leaf spring 11 and the pressing protrusion 12 can be replaced with a hook-and-loop fastener or a magnet.
