Summary of the Invention

Problems to be Solved by the Invention

[0004] According to the prefabricated pole hanger disclosed in Patent Document 1, square columnar connection chips are inserted and arranged in the longitudinal direction of a round bar, and the lower inner curved portion of a U-shaped protruding fitting is inserted into a circumferential groove formed at the mutual contact portion of the connection chips, and the protruding fitting is held outside the connection chips. At the same time, both side slits of the U-shaped piece in the holding fitting facing the opposite side of the protruding fitting are locked to tongue pieces protruding from both sides of the protruding fitting to fix the holding fitting to the protruding fitting, and then a pressing lid is provided on the uppermost connection chip. However, according to such a configuration, the number of components is large, and it is difficult to attach to a rod-shaped member easily and surely. Further, for example, when there is a rod-shaped member extending in the vertical direction from the ceiling surface to the floor surface, in the technique disclosed in Patent Document 1 described above, it is necessary to remove the rod-shaped member from the state where it is arranged between the ceiling surface and the floor surface once and then insert the connection chip, and the attachment work becomes complicated.

[0005] One of the objectives is to provide a fixture that can be easily and surely attached to a rod-shaped member.

BEST MODE FOR CARRYING OUT THE INVENTION

[0009] [Description of Embodiments of the Present Disclosure] First, embodiments of the present disclosure will be listed and described. The attachment tool according to the present disclosure is attached to the outer surface of a rod-shaped member. The attachment tool includes a first portion including a first holding portion having a first inner surface shaped along a part of the outer surface of the rod-shaped member and a first protruding portion extending outward from a part of the first holding portion, a second portion including a second holding portion having a second inner surface shaped along a part of the outer surface of the rod-shaped member and a second protruding portion extending outward from a part of the second holding portion, and being configured to be rotatable with respect to the first portion about a shaft portion as a rotation center axis, a connecting portion including the shaft portion and connecting the second portion rotatably with respect to the first portion so that a closed state in which the interval between the first protruding portion and the second protruding portion is narrow and an open state in which the interval between the first protruding portion and the second protruding portion is wider than the closed state can be taken, and a closed state maintaining portion for maintaining the closed state.

[0010] The mounting fixture of this disclosure is rotatably connected by a connecting portion including a shaft portion, such that the first portion and the second portion can be in an open state and a closed state when viewed from the direction in which the rotational axis extends. For mounting the mounting fixture, first, the rod-shaped member is placed inside with the first portion and the second portion in an open state. Then, the outer surface of the rod-shaped member is sandwiched between the first portion and the second portion to create a closed state. Finally, the closed state of the first portion and the second portion is maintained by a closed state maintenance portion. With this mounting method, the risk of the mounting work becoming complicated can be reduced. In particular, when mounting the mounting fixture to a rod-shaped member that extends from the ceiling surface to the floor surface, the mounting fixture can be attached from the outer surface side of the rod-shaped member, so that the mounting fixture can be attached while the rod-shaped member remains positioned between the ceiling surface and the floor surface. Therefore, work efficiency can be greatly improved. Furthermore, if it is desired to change the mounting position of the mounting fixture after it has been attached to the rod-shaped member in the longitudinal direction of the rod-shaped member, the closed state maintained by the closed state maintenance part can be released, the mounting position can be changed from the closed state to the open state, the mounting fixture can be moved to the desired position, and then the closed state can be maintained again by the closed state maintenance part. Therefore, it is easy to change the mounting position on the rod-shaped member. In addition, since the first inner surface and the second inner surface each have a shape that follows a part of the outer surface of the rod-shaped member, a wide contact area can be secured between the first inner surface and the second inner surface and the outer surface of the rod-shaped member, allowing the mounting fixture to be attached to the rod-shaped member more stably. Moreover, by utilizing the first and second protrusions, it becomes easy to provide various functional components such as trays and boxes on the mounting fixture. As described above, such a mounting fixture can be easily and reliably attached to a rod-shaped member.

[0011] In the above-described mounting device, the first projection may include a first opposing surface that faces the second projection when closed, and a first end surface that intersects with the first opposing surface. The first end surface may be provided with a first recess. By doing so, a functional component can be attached to the mounting device using the first recess provided on the first end surface of the first projection. Therefore, the convenience of the mounting device can be improved.

[0012] In the above-described mounting device, the second projection may include a second opposing surface that faces the first projection when closed, and a second end surface that intersects with the second opposing surface. The second end surface may be provided with a second recess. In this way, in addition to the first recess, the second recess provided on the second end surface of the second projection can be used to attach a functional component to the mounting device. In this case, since both the first recess and the second recess can be used, the functional component can be attached stably. Therefore, the convenience of the mounting device can be further improved.

[0013] In the above-described mounting fixture, the first recess may penetrate in a direction perpendicular to the first end face. The second recess may penetrate in a direction perpendicular to the second end face. By doing so, even if the mounting fixture is installed upside down, the first and second recesses can be effectively utilized to attach the functional component. Therefore, it becomes possible to use it in a more versatile manner.

[0014] In the above-described mounting device, a sheet-like anti-slip member having a coefficient of friction greater than that of the first inner surface and the second inner surface may be attached to at least one of them. By doing so, the anti-slip member attached to either the first inner surface or the second inner surface reduces the risk of the mounting device rotating relative to the outer surface of the rod-shaped member or moving from its mounting position. Therefore, the mounting device can be attached more stably.

[0015] In the above-described mounting device, at least one of the first inner surface and the second inner surface may be provided with a protrusion that is positioned adjacent to the anti-slip member and rises inward. By doing so, even if the anti-slip member attempts to move from its mounting position, the protrusion can restrict the movement of the anti-slip member. This reduces the risk of the anti-slip member shifting position or falling off the inner surface. Therefore, the mounting device can be attached more stably over a long period of time.

[0016] In the above-described mounting device, the first inner surface and the second inner surface may each include an arc-shaped surface. By doing so, when the rod-shaped member is cylindrical, the outer surface can be properly fitted to the first inner surface and the second inner surface, allowing the mounting device to be attached. Therefore, the mounting device can be attached more stably.

[0017] In the above-described mounting device, the connecting portion may have a hinge structure. This allows for easy switching between the open state and the closed state while maintaining proper connection between the first and second portions. Therefore, the mounting device can be constructed more simply.

[0018] In the above-described fastening device, the second projection may be provided with a fastening through-hole that penetrates from the second opposing surface. The first projection may be provided with a fastening recess that is recessed from the first opposing surface and has a screw groove formed therein. The closed state maintenance part may include a bolt having a head and a body extending from the head. The closed state maintenance part may maintain the closed state by inserting the body through the fastening through-hole and fastening the body to the fastening recess. In this way, the first and second parts of the closed state can be fastened by the bolt included in the closed state maintenance part using the fastening through-hole and the fastening recess. Therefore, the risk of the closed state becoming open can be further reduced by fastening with the above-described closed state maintenance part.

[0019] In the above-described mounting device, the closed state maintenance portion may include a hooking member formed by bending a cylindrical member. The closed state maintenance portion may maintain the closed state by inserting one end of the hooking member into the first recess and the other end of the hooking member into the second recess. In this way, the closed state can be maintained using the hooking member. Therefore, the closed state can be maintained more easily.

[0020] In the above-described mounting device, the hooking member may include a first functional component. The first functional component may include at least one of a box, a tray, and a hook. By doing so, the first functional component included in the hooking member can be used to improve user convenience.

[0021] In the above-described mounting device, the closed state maintenance portion may include a stopper member having portions that are inserted into the first recess and the second recess. The stopper member may include a rod-shaped first insertion portion that can be inserted into the first recess, a rod-shaped second insertion portion that extends in the same direction as the first insertion portion, is positioned at a distance from the first insertion portion, and can be inserted into the second recess, and a connecting portion that connects one end of the first insertion portion and one end of the second insertion portion. In this way, the closed state of the first and second portions can be maintained using the stopper member. In this case, a stopper member with a relatively simple structure can be used, thus simplifying the configuration and improving productivity.

[0022] In the above-described mounting device, the connecting portion may extend in a direction intersecting the direction in which the first and second insertion portions extend. By doing so, the structure of the stopper member can be further simplified. Therefore, productivity can be further improved.

[0023] In the above-described mounting device, at least one of the other end of the first insertion portion and the other end of the second insertion portion may taper towards the tip. This makes it easier to insert the first insertion portion and the second insertion portion into the first recess and the second recess, respectively. Therefore, it becomes easier to maintain the closed state.

[0024] In the above-described mounting device, the first insertion portion and the second insertion portion may each be solid cylindrical. This makes it easier to maintain high rigidity in the first and second insertion portions. Therefore, it becomes easier to reliably maintain a closed state over a long period of time.

[0025] In the above-described mounting device, the connecting portion may be flat. By doing so, when the first insertion portion and the second insertion portion are inserted into the first recess and the second recess, respectively, to maintain the closed state, the risk of the stopper member becoming bulky in the insertion direction can be reduced. Therefore, the risk of the stopper member coming off the first and second portions can be reduced, and the appearance can be improved.

[0026] In the above-described mounting fixture, a second functional component may be attached to the first and second parts. The second functional component may include at least one of a panel, a table, a hook, a hanger pole, and a bar. By doing so, the user's convenience can be improved by utilizing the second functional component attached to the first and second parts.

[0027] In the above-described mounting device, the second functional component may be provided with a first insertion hole and a second insertion hole. The second functional component may be mounted by inserting the first insertion part into the first insertion hole so as to contact the first end face and the second end face, respectively, and then inserting the second insertion part into the second insertion hole. By doing so, it becomes easy to properly mount the second functional component to the first and second parts while maintaining the closed state by using the stopper member. Therefore, it becomes easy to achieve efficient mounting of the second functional component and maintenance of the closed state.

[0028] [Details of the embodiments of this disclosure] Next, embodiments of the mounting fixtures of this disclosure will be described with reference to the drawings. In the following drawings, the same or corresponding parts are denoted by the same reference numerals, and their descriptions will not be repeated.

[0029] (Embodiment 1) A mounting device according to Embodiment 1 of this disclosure will now be described. Figure 1 is a schematic perspective view showing the appearance of the mounting device and the rod-shaped member to which the mounting device is attached in Embodiment 1. Figure 2 is a schematic front view of the rod-shaped member shown in Figure 1. Figure 2 is a view of the rod-shaped member shown in Figure 1 in the direction indicated by arrow II in Figure 1. Figure 3 is a schematic rear view of the rod-shaped member shown in Figure 1. Figure 3 is a view of the rod-shaped member shown in Figure 1 in the direction indicated by arrow III in Figure 1. Figure 4 is a schematic perspective view showing the rod-shaped member shown in Figure 1 with the mounting device removed. For ease of understanding, in the following description, the direction indicated by arrow Z will be referred to as upward, and the direction indicated by arrow Y will be referred to as forward (front-facing). Also, the direction indicated by arrow X or its opposite will be referred to as left-right direction.

[0030] Referring to Figures 1, 2, 3, and 4, in this embodiment, the rod-shaped member 10a to which the mounting fixture is attached is installed so that its longitudinal direction is vertical, i.e., the top-down direction. In this embodiment, the rod-shaped member 10a is a tension rod. That is, it is installed between the floor surface and the ceiling surface under tension so that its longitudinal direction is vertical. The rod-shaped member 10a includes a first cylindrical portion 11a, a second cylindrical portion 12a, and a joint portion 13a. The first cylindrical portion 11a includes a first end portion 14a that contacts the ceiling surface or floor surface when installed. The second cylindrical portion 12a includes a second end portion 15a that contacts the floor surface or ceiling surface when installed. When the first end portion 14a contacts the ceiling surface, the second end portion 15a is installed so that it contacts the floor surface, and when the first end portion 14a contacts the floor surface, the second end portion 15a is installed so that it contacts the ceiling surface.

[0031] The inner circumference of the first cylindrical portion 11a can accommodate a portion of the second cylindrical portion 12a. The joint portion 13a is attached to the first cylindrical portion 11a. The joint portion 13a includes a sleeve portion 16a and a knob portion 17a. A spring (not shown) as an elastic member is provided inside at least one of the first cylindrical portion 11a and the second cylindrical portion 12a. The rod-shaped member 10a adjusts the length of the second cylindrical portion 12a that is accommodated on the inner circumference of the first cylindrical portion 11a, and is positioned between the ceiling surface and the floor surface such that the first end portion 14a and the second end portion 15a are in contact with the ceiling surface, respectively. Then, using the biasing force of the spring, the rod-shaped member 10a is pushed out by tightening the knob portion 17a by rotating the joint portion 13a, pressing it against the ceiling surface and the floor surface. In this way, the rod-shaped member 10a is installed while maintaining tension between two opposing surfaces, in this embodiment, between the ceiling surface and the floor surface.

[0032] Various first functional components are attached to the rod-shaped member 10a. Specifically, the rod-shaped member 10a is fitted with a hook 21a as a first functional component, a deep box 22a as a first functional component, a shallow box 23a as a first functional component, and a tray 24a as a first functional component. The hook 21a can be used to hang and store items such as bags or hats that have a string-like portion. The boxes 22a and 23a each have through holes, allowing items to be stored by placing them inside. The tray 24a has a flat, dish-like portion on which items can be placed. The hook 21a, boxes 22a and 23a, and tray 24a are each attached to the rod-shaped member 10a via a mounting fixture 40a.

[0033] Next, the configuration of the mounting fixture 40a in Embodiment 1 will be described. Figures 5 and 6 are schematic perspective views of the mounting fixture 40a in Embodiment 1, respectively. Figure 5 shows the mounting fixture 40a in a closed state, and Figure 6 shows the mounting fixture 40a in an open state. Figure 7 is a schematic plan view of the mounting fixture 40a in the closed state shown in Figure 5. Figure 8 is a schematic plan view of the mounting fixture 40a in the open state shown in Figure 6. Note that the closed state maintenance part is not shown in Figures 5 to 8. Referring to Figures 5, 6, 7 and 8, the mounting fixture 40a is attached to the outer surface 18a of the rod-shaped member 10a.

[0034] The mounting fixture 40a includes a first part 41a, a second part 42a, a connecting part 43a, and a closed state maintaining part 44a (see Figure 10, described later). The connecting part 43a includes a shaft part 45a. The second part 42a is configured to be rotatable relative to the first part 41a with the shaft part 45a as the rotational axis. This will be described later. The first part 41a includes a first holding part 51a and a first protruding part 52a. The second part 42a includes a second holding part 61a and a second protruding part 62a. The configuration of the closed state maintaining part 44a will be described in detail later.

[0035] The first retaining portion 51a has a first inner surface 53a that conforms to a part of the outer surface 18a of the rod-shaped member 10a. The first inner surface 53a includes an arc-shaped surface. In this embodiment, the first inner surface 53a is semi-arc-shaped. The first retaining portion 51a also has a semi-arc shape when viewed from the Z direction. An anti-slip member (first anti-slip member 54a) is attached to the first inner surface 53a. The first anti-slip member 54a is in the form of a sheet. In this embodiment, the first anti-slip member 54a is attached to a part of the first inner surface 53a. The coefficient of friction of the first anti-slip member 54a is greater than the coefficient of friction of the first inner surface 53a. The material of the first anti-slip member 54a is synthetic rubber.

[0036] The first inner surface 53a is provided with a protrusion (first protrusion 55a) that rises inward. The first protrusion 55a is positioned adjacent to the first anti-slip member 54a. In this embodiment, the first protrusion 55a is provided in a band shape that extends circumferentially in the region on the upper end side of the first inner surface 53a. The protruding length of the first protrusion 55a is such that it does not interfere with the outer surface 18a of the rod-shaped member 10a when it is closed. The same applies to the second protrusion 65a, which will be described later.

[0037] The first projection 52a extends outward from a part of the first retaining portion 51a. In this embodiment, the first projection 52a extends outward from a region including the circumferential end of the semi-circular first retaining portion 51a. The first projection 52a includes a first opposing surface 56a that faces the second projection 62a when closed, and an upper first end surface 57a and a lower first end surface 58a that intersect with the first opposing surface 56a and are orthogonal in this embodiment. The lower first end surface 58a is orthogonal to the first opposing surface 56a and is provided to be parallel to the upper first end surface 57a with a gap in the Z direction. The first opposing surface 56a and the upper first end surface 57a are both planar. A first recess 59a is provided on the upper first end surface 57a. The first recess 59a is a round hole that penetrates in the Z direction. Specifically, the first recess 59a penetrates from the upper first end face 57a to the lower first end face 58a.

[0038] The second holding portion 61a has a second inner surface 63a that conforms to a part of the outer surface 18a of the rod-shaped member 10a. The second inner surface 63a includes an arc-shaped surface. In this embodiment, the second inner surface 63a is semi-arc-shaped. When the first portion 41a and the second portion 42a are closed, the first inner surface and the second inner surface are configured to form an arc shape when viewed in the Z direction. The second holding portion 61a has a semi-arc shape when viewed in the Z direction. An anti-slip member (second anti-slip member 64a) is attached to the second inner surface 63a. The second anti-slip member 64a is in the form of a sheet. In this embodiment, the second anti-slip member 64a is attached to a part of the second inner surface 63a. The coefficient of friction of the second anti-slip member 64a is greater than the coefficient of friction of the second inner surface 63a. The material of the second anti-slip member 64a is synthetic rubber, the same as the first anti-slip member 54a.

[0039] The second inner surface 63a is provided with a protruding portion (second protrusion 65a) that rises inward. The second protrusion 65a is positioned adjacent to the second anti-slip member 64a. In this embodiment, the second protrusion 65a is provided in a band shape that extends circumferentially in the region on the upper end side of the second inner surface 63a.

[0040] The second projection 62a extends outward from a part of the second retaining portion 61a. In this embodiment, the second projection 62a extends outward from a region including the circumferential end of the semi-circular second retaining portion 61a. The second projection 62a includes a second opposing surface 66a that faces the first projection 52a, specifically the first opposing surface 56a, when closed, and an upper second end surface 67a that intersects with the second opposing surface 66a and is perpendicular in this embodiment, and a lower second end surface 68a. The lower second end surface 68a is perpendicular to the second opposing surface 66a and is provided to be parallel to the upper second end surface 67a with a gap in the Z direction. The second opposing surface 66a and the upper second end surface 67a are both planar. A second recess 69a is provided on the upper second end surface 67a. The second recess 69a is a circular hole that penetrates in the Z direction. Specifically, the second recess 69a penetrates from the upper second end face 67a to the lower second end face 68a. Furthermore, the radial position where the second recess 69a is provided is aligned with the radial position where the first recess 59a is provided.

[0041] The connecting portion 43a includes the shaft portion 45a as described above and connects the first portion 41a and the second portion 42a. The shaft portion 45a is positioned so that its longitudinal direction is the Z direction. In this case, the connecting portion 43a connects the second portion 42a to the first portion 41a so that it can rotate around the shaft portion 45a as the axis of rotation. Specifically, the connecting portion 43a connects the first end portion 46a of the first portion 41a and the second end portion 47a of the second portion 42a. In this embodiment, the first end portion 46a is the circumferential end portion of the first holding portion 51a of the first portion 41a. Two first end portions 46a are provided, separated in the Z direction. The second end portion 47a is the circumferential end portion of the second holding portion 61a of the second portion 42a. The second end portion 47a is provided so as to be located between the two first end portions 46a, which are provided separated in the Z direction. The second end portion 47a is provided to fit into the first end portion 46a. The shaft portion 45a is fitted into a first shaft portion fitting hole 48a that penetrates in the Z direction and is provided in the first end portion 46a, and a second shaft portion fitting hole (not shown) that penetrates in the Z direction and is provided in the second end portion 47a, thereby making the second portion 42a rotatable.

[0042] The connecting portion 43a rotatably connects the second portion 42a to the first portion 41a so that it can take on a closed state in which the distance between the first protrusion 52a and the second protrusion 62a is narrow when viewed from the direction in which the rotational axis extends (Z direction), and an open state in which the distance between the first protrusion 52a and the second protrusion 62a is wider than in the closed state. The connecting portion 43a, including the shaft portion 45a, allows the mounting fixture 40a to take on both a closed and an open state. That is, with the shaft portion 45a as the rotational axis, the second portion 42a is supported so as to be rotatable by a predetermined angle relative to the first portion 41a. The connecting portion 43a has a hinge structure composed of the shaft portion 45a, the first shaft portion fitting hole 48a, and the second shaft portion fitting hole.

[0043] A fastening through hole 71a is provided on the second opposing surface 66a of the second projection 62a. The fastening through hole 71a is provided so as to penetrate straight through in a direction perpendicular to the second opposing surface 66a. A fastening recess 72a with a screw groove formed inside is provided on the first opposing surface 56a of the first projection 52a. The fastening recess 72a is provided at a position on the extension of the fastening through hole 71a in the penetrating direction when the bolt is closed, i.e., when the distance between the first projection 52a and the second projection 62a is narrow. The closed state maintenance part 44a includes a bolt 73a having a head 74a and a body 75a extending from the head 74a. The closed state maintenance part 44a maintains the closed state by inserting the body 75a through the fastening through hole 71a and fastening the body 75a to the fastening recess 72a.

[0044] The closed state maintenance part 44a includes a hook member 81a. Figure 9 is a schematic perspective view of the hook member 81a. The hook member 81a shown in Figure 9 corresponds to the hook 21a shown in Figures 1 to 3. Figures 10 and 11 are schematic perspective views showing the hook member 81a attached to the mounting fixture 40a. For ease of understanding, the state in which the hook member 81a is attached to the mounting fixture 40a is referred to as the mounting unit 80a. Figures 10 and 11 are schematic perspective views from different angles. Figure 12 is a schematic front view of the mounting unit 80a shown in Figure 10. Figure 12 is a view in the direction indicated by arrow XII in Figure 10. Figure 13 is a schematic rear view of the mounting unit 80a shown in Figure 10. Figure 13 is a view of the mounting unit 80a shown in Figure 10 in the direction indicated by arrow XIII. Figure 14 is a schematic side view of the mounting unit 80a shown in Figure 10. Figure 14 is a view of the mounting unit 80a shown in Figure 10, as indicated by arrow XIV. Figure 15 is a schematic bottom view of the mounting unit 80a shown in Figure 10. Figure 15 is a view of the mounting unit 80a shown in Figure 10, as indicated by arrow XV.

[0045] Referring to Figures 9 to 15, the hooking member 81a is formed by bending a cylindrical member. For ease of understanding, the configuration of the hooking member 81a shown in Figure 9 will be explained using the directions of arrows X, Y, and Z when the hooking member 81a is attached to the mounting fixture 40a. In this embodiment, the hooking member 81a is formed by bending a solid cylindrical member. The material of the hooking member 81a is metal. Specifically, the hooking member 81a is formed by bending a single metal round bar into a hook shape. The hooking member 81a includes a pair of claw portions 82a, 83a provided at positions corresponding to both ends of the round bar, a pair of extension portions 84a, 85a provided to extend straight for hooking objects, and a central portion 86a provided to connect the pair of extension portions 84a, 85a. Each pair of claw portions 82a and 83a are provided to extend straight in the Z direction with a gap in the X direction. The pair of claw portions 82a and 83a are provided to be parallel to each other. Each pair of extension portions 84a and 85a are provided to extend straight in the Y direction with a gap in the X direction. The pair of extension portions 84a and 85a are provided to be parallel to each other. The hooking member 81a includes a bent portion 87a that is bent to connect the claw portion 82a and the extension portion 84a, and a bent portion 88a that is bent to connect the claw portion 83a and the extension portion 85a.

[0046] The hooking member 81a is attached by inserting the claw portion 82a into the first recess 59a provided on the first projection 52a, and the claw portion 83a into the second recess 69a provided on the second projection 62a. Since the claw portions 82a and 83a extend in the Z direction and are connected to the bent portions 87a and 88a, they catch on the first projection 52a and the second projection 62a, respectively, at the bent portions 87a and 88a, and are locked in place.

[0047] Furthermore, the boxes 22a, 23a and tray 24a shown in Figures 1 to 3 above are provided with parts corresponding to the claw portions 82a and 83a described above. The boxes 22a, 23a and tray 24a are attached using the mounting fixture 40a, utilizing the claw portions 82a and 83a.

[0048] Next, an example of the procedure for attaching the mounting fixture 40a to the rod-shaped member 10a will be described. Figure 16 is a schematic perspective view of the case when the mounting fixture 40a is attached to the rod-shaped member 10a. Note that in Figure 16, some parts of the rod-shaped member 10a are omitted from the illustration. Referring to Figure 16 as well, first, with the first part 41a and the second part 42a in an open state, advance in the direction indicated by the arrow V1 in Figure 16. Then, the outer surface 18a of the rod-shaped member 10a is pressed against the area where the connecting part 43a is located. That is, with the first part 41a and the second part 42a in an open state, the rod-shaped member 10a is positioned inside. After that, the outer surface 18a of the rod-shaped member 10a is sandwiched between the first part 41a and the second part 42a to create a closed state. In this case, the first inner surface 53a of the first retaining portion 51a and the second inner surface 63a of the second retaining portion 61a come into contact with the outer surface 18a of the rod-shaped member 10a. In this case, the first anti-slip member 54a attached to the first inner surface 53a and the second anti-slip member 64a attached to the second inner surface 63a mainly come into contact with the outer surface 18a of the rod-shaped member 10a.

[0049] After achieving this state, the body portion 75a of the bolt 73a included in the closed state maintenance portion 44a is inserted through the fastening through hole 71a, and the body portion 75a is rotated to fasten the bolt 73a to the fastening recess 72a which has a screw groove. In this way, the closed state is maintained by the closed state maintenance portion 44a. Subsequently, the claw portions 82a and 83a of the hooking member 81a are hooked onto the first recess 59a and the second recess 69a, and the hooking member 81a is attached to the mounting fixture 40a. In this way, the mounting fixture 40a and the hooking member 81a are attached to the outer surface 18a of the rod-shaped member 10a.

[0050] With this type of mounting device 40a, the first part 41a and the second part 42a are rotatably connected by a connecting part 43a including a shaft part 45a, so that they can be in an open state and a closed state when viewed from the direction in which the rotational center axis extends. To install the mounting device 40a, first, the rod-shaped member 10a is placed inside with the first part 41a and the second part 42a in an open state. Then, the outer surface 18a of the rod-shaped member 10a is sandwiched between the first part 41a and the second part 42a to create a closed state. Finally, the closed state of the first part 41a and the second part 42a is maintained by the closed state maintenance part 44a. With this type of mounting, the risk of the installation work becoming complicated can be reduced. In particular, when attaching the mounting fixture 40a to a rod-shaped member 10a that extends from the ceiling to the floor, the mounting fixture 40a can be attached from the outer surface 18a side of the rod-shaped member 10a. Therefore, the mounting fixture 40a can be attached while the rod-shaped member 10a remains positioned between the ceiling and the floor. This significantly improves work efficiency. Furthermore, if it is desired to change the mounting position of the mounting fixture 40a after it has been attached to the rod-shaped member 10a in the longitudinal direction of the rod-shaped member 10a, the closed state maintained by the closed state maintenance unit 44a can be released, the mounting position can be changed from the closed state to the open state, the mounting fixture 40a can be moved to the desired position, and then the closed state can be maintained again by the closed state maintenance unit 44a. Therefore, changes to the mounting position on the rod-shaped member 10a can be easily accommodated. Furthermore, since the first inner surface 53a and the second inner surface 63a each have a shape that follows a part of the outer surface 18a of the rod-shaped member 10a, a large contact area can be secured between the first inner surface 53a and the second inner surface 63a and the outer surface 18a of the rod-shaped member 10a, allowing the mounting fixture 40a to be attached to the rod-shaped member 10a more stably. In addition, by utilizing the first protrusion 52a and the second protrusion 62a, it becomes easy to provide various first functional components such as trays 24a and boxes 22a and 23a on the mounting fixture 40a. As described above, such a mounting fixture 40a can be easily and reliably attached to the rod-shaped member 10a.

[0051] In this embodiment, the first projection 52a includes a first opposing surface 56a that faces the second projection 62a when closed, and an upper first end surface 57a that intersects with the first opposing surface 56a. The upper first end surface 57a is provided with a first recess 59a. Therefore, the first functional component can be attached to the mounting fixture 40a by utilizing the first recess 59a provided on the upper first end surface 57a of the first projection 52a. Thus, the convenience of the mounting fixture 40a can be improved.

[0052] In this embodiment, the second projection 62a includes a second opposing surface 66a that faces the first projection 52a when closed, and an upper second end surface 67a that intersects with the second opposing surface 66a. The upper second end surface 67a is provided with a second recess 69a. Therefore, in addition to the first recess 59a, the first functional component can be attached to the mounting fixture 40a by utilizing the second recess 69a provided on the upper second end surface 67a of the second projection 62a. In this case, since both the first recess 59a and the second recess 69a can be utilized, the first functional component can be attached stably. Thus, the convenience of the mounting fixture 40a can be further improved.

[0053] In this embodiment, the first recess 59a penetrates the upper first end face 57a in a direction perpendicular to it. The second recess 69a penetrates the upper second end face 67a in a direction perpendicular to it. Therefore, even if the mounting fixture 40a is installed upside down, the first functional component can be attached by effectively utilizing the first recess 59a and the second recess 69a. Thus, more versatile use becomes possible.

[0054] In this embodiment, the first inner surface 53a and the second inner surface 63a are fitted with sheet-like first anti-slip members 54a and second anti-slip members 64a, each having a coefficient of friction greater than that of the first inner surface 53a and the second inner surface 63a, respectively. Therefore, the first anti-slip members 54a and second anti-slip members 64a fitted to the first inner surface 53a and the second inner surface 63a reduce the risk of the mounting fixture 40a rotating relative to the outer surface 18a of the rod-shaped member 10a or moving from its mounting position. Consequently, the mounting fixture 40a can be mounted more stably.

[0055] In this embodiment, the first inner surface 53a and the second inner surface 63a are provided with a first protrusion 55a and a second protrusion 65a that are positioned adjacent to the first anti-slip member 54a and the second anti-slip member 64a, respectively, and that protrude inward. Therefore, even if the first anti-slip member 54a and the second anti-slip member 64a attempt to move from their respective mounting positions, the first protrusion 55a and the second protrusion 65a restrict their movement. This reduces the risk of the first anti-slip member 54a and the second anti-slip member 64a shifting position or falling off the first inner surface 53a and the second inner surface 63a. Consequently, the mounting fixture 40a can be attached more stably over a long period of time.

[0056] In this embodiment, the first inner surface 53a and the second inner surface 63a each include an arc-shaped surface. Therefore, when the rod-shaped member 10a is cylindrical, the outer surface 18a can be properly fitted with the first inner surface 53a and the second inner surface 63a to attach the mounting fixture 40a. Consequently, the mounting fixture 40a can be attached more stably.

[0057] In this embodiment, the connecting portion 43a has a hinge structure. Therefore, the open state and the closed state can be easily switched while maintaining a proper connection between the first portion 41a and the second portion 42a. Consequently, the mounting fixture 40a can be constructed more simply.

[0058] In this embodiment, the second projection 62a is provided with a fastening through hole 71a that penetrates from the second opposing surface 66a. The first projection 52a is provided with a fastening recess 72a that is recessed from the first opposing surface 56a and has a screw groove formed therein. The closed state maintenance part 44a includes a bolt 73a having a head 74a and a body 75a extending from the head 74a. The closed state maintenance part 44a maintains the closed state by inserting the body 75a through the fastening through hole 71a and fastening the body 75a to the fastening recess 72a. Therefore, the first part 41a and the second part 42a in the closed state can be fastened by the bolt 73a included in the closed state maintenance part 44a using the fastening through hole 71a and the fastening recess 72a. Consequently, the risk of the closed state becoming open can be further reduced by fastening with the closed state maintenance part 44a.

[0059] In the above embodiment, the closed state maintenance part may include a hooking member formed by bending a cylindrical member. The closed state maintenance part may maintain the closed state by inserting one end of the hooking member into the first recess and the other end of the hooking member into the second recess. In this way, the closed state can be maintained using the hooking member. Therefore, the closed state can be maintained more easily.

[0060] (Embodiment 2) In Embodiment 1, the mounting device includes a hook member in the closed state maintenance section, but it is not limited to this configuration, and the closed state maintenance section may also include a stopper member. Figure 17 is a schematic perspective view showing the appearance of the mounting device and the rod-shaped member to which the mounting device is attached in Embodiment 2. Figure 18 is a schematic front view of the rod-shaped member shown in Figure 17. Figure 18 is a view of the rod-shaped member shown in Figure 17 in the direction indicated by arrow XVIII in Figure 17. Figure 19 is a schematic rear view of the rod-shaped member shown in Figure 17.

Figure 20 is a view of the rod-shaped member shown in Figure 17 in the direction indicated by arrow XX in Figure 17.

[0061] Referring to Figures 17, 18, 19, and 20, the configuration of the rod-shaped member 10b is the same as that of the rod-shaped member 10a in Embodiment 1, except for the configuration of the first end 14b, which has a pad attached to the member corresponding to the first end 14a, and the second end 15b, which has a pad attached to the second end 15a. Therefore, a description of the configuration is omitted. Various second functional components are attached to the rod-shaped member 10b. Specifically, the rod-shaped member 10b is fitted with a panel 21b as a second functional component, a table 22b as a second functional component, a hook 23b as a second functional component, a hanger pole 24b as a second functional component, and a bar 25b as a second functional component. The panel 21b is flat and has multiple through holes, and objects can be attached to the panel 21b using these multiple through holes. Objects can be placed on the table 22b. Furthermore, the table 22b has two tiers, and items can be placed between the two tiers of the table 22b in a concealed manner. The hook 23b is formed by shaping a round rod into an annular shape that is elongated in the Z direction, and can be used to hang and store items such as bags and hats that have string-like parts. The hanger pole 24b is formed by shaping a round rod into an annular shape that is elongated in the X direction, and can be used to hang and hold clothes and small items by attaching hangers to it. The bar 25b is a rod-shaped member that extends in the X direction, and items can also be hung and suspended from the bar 25b. The panel 21b, table 22b, hook 23b, hanger pole 24b, and bar 25b are each attached to the rod-shaped member 10b via mounting fixtures 40b.

[0062] Next, the configuration of the mounting fixture 40b in Embodiment 2 will be described. Figure 21 is a schematic front view of the stopper member 80b included in the mounting fixture 40b. Figure 21 is a view of the stopper member 80b in the opposite direction to that indicated by arrow Y. Figure 22 is a schematic top view of the stopper member 80b included in the mounting fixture 40b. Figure 22 is a view of the stopper member 80b in the opposite direction to that indicated by arrow Z. Figure 23 is a schematic side view of the stopper member 80b included in the mounting fixture 40b. Figure 23 is a view of the stopper member 80b in the opposite direction to that indicated by arrow X.

[0063] Referring together to Figures 21, 22, and 23, the closed state maintenance portion 44b of the mounting fixture 40b includes a stopper member 80b having portions that are inserted into the first recess 59a and the second recess 69a. The stopper member 80b includes a rod-shaped first insertion portion 81b that can be inserted into the first recess 59a, a rod-shaped second insertion portion 82b that extends in the same direction as the first insertion portion 81b, is spaced apart from the first insertion portion 81b, and can be inserted into the second recess 69a, and a connecting portion 83b that connects one end of the first insertion portion 81b and one end of the second insertion portion 82b. In this embodiment, when the mounting fixture 40b is installed, the first insertion portion 81b and the second insertion portion 82b each extend in the Z direction. The connecting portion 83b extends in a direction intersecting the direction in which the first insertion portion 81b and the second insertion portion 82b extend. Specifically, when the mounting fixture 40b is installed, the connecting portion 83b extends in the X direction. The first insertion portion 81b and the second insertion portion 82b are each solid cylindrical in shape. The first insertion portion 81b and the second insertion portion 82b each have a shape that tapers towards the tip of the other end. The connecting portion 83b is flat. The stopper member 80b is made of resin.

[0064] Figure 24 is a schematic perspective view showing the panel 21b as a second functional component mounted together with the mounting fixture 40b. For ease of understanding, the rod-shaped member 10b is omitted from the illustration in Figure 24. The same applies to Figures 24 and subsequent figures. Referring to Figure 24, the panel 21b includes two first flat plate sections 26b and 27b parallel to the XY plane, and a second flat plate section 28b parallel to the XZ plane. The first flat plate sections 26b and 27b are connected to the upper and lower ends of the second flat plate section 28b, respectively. The second flat plate section 28b is provided with a plurality of through holes penetrating in the Y direction. The first flat plate sections 26b and 27b are provided with a first insertion hole 84b and a second insertion hole 85b penetrating in the Z direction, respectively. The first insertion hole 84b and the second insertion hole 85b are spaced apart in the X direction. Furthermore, the first flat plate portions 26b and 27b are each provided with a notch 86b cut out along the outer surface 18a of the first cylindrical portion 11a.

[0065] The panel 21b is attached as follows: The first portion 41a and the second portion 42a are attached to the rod-shaped member 10b so that they are closed. Then, the first flat plate portion 26b is placed on the first end surface and the second end surface, with the first insertion hole 84b aligned with the position of the first recess 59a and the second insertion hole 85b aligned with the position of the second recess 69a. Then, the first insertion portion 81b is inserted into the first recess 59a by passing through the first insertion hole 84b, and the second insertion portion 82b is inserted into the second recess 69a by passing through the second insertion hole 85b. In this way, the panel 21b as a second functional component is attached to the first portion 41a and the second portion 42a by the stopper member 80b.

[0066] Figure 25 is a schematic perspective view showing the table 22b as a second functional component mounted together with the mounting fixture 40b. Referring to Figure 25, the table 22b includes two first flat plate portions 29b and 31b parallel to the XY plane, and a second flat plate portion 32b parallel to the XZ plane. The pair of first flat plate portions 29b and 31b are spaced apart in the Z direction. The upper and lower ends of the second flat plate portion 32b are connected to the first flat plate portions 29b and 31b, respectively. The upper first flat plate portion 29b is provided with a first insertion hole 87b and a second insertion hole 88b that penetrate in the Z direction, respectively.

The first flat plate portion 29b is also provided with a notch 89b cut out along the outer surface 18a of the first cylindrical portion 11a. The first flat plate sections 29b and 31b are supported by multiple support columns 33b.

[0067] The table 22b is attached as follows: The first portion 41a and the second portion 42a are attached to the rod-shaped member 10b so that they are closed. Then, the first flat plate portion 29b is placed on the first end surface and the second end surface, with the first insertion hole 87b aligned with the position of the first recess 59a and the second insertion hole 88b aligned with the position of the second recess 69a.

In this way, the table 22b as a second functional component is attached to the first portion 41a and the second portion 42a by the stopper member 80b.

[0068] Figure 26 is a schematic perspective view showing the hook 23b as a second functional component attached together with the mounting fixture 40b. Referring to Figure 26, the hook 23b includes a first ring-shaped portion 34b whose length in the Z direction is longer than its length in the X direction, and a first support portion 35b that supports the first ring-shaped portion 34b. The first support portion 35b is shaped by bending a single strip-shaped member. The first support portion 35b is provided with a first insertion hole 91b and a second insertion hole 92b that penetrate in the Z direction, and a notch 93b. The first insertion hole 91b and the second insertion hole 92b are spaced apart in the X direction.

[0069] The hook 23b is attached as follows: The first portion 41a and the second portion 42a are attached to the rod-shaped member 10b so that they are closed. Then, the first support portion 35b is placed on the first end surface and the second end surface, with the first insertion hole 91b aligned with the first recess 59a and the second insertion hole 92b aligned with the second recess 69a. Then, the first insertion portion 81b is inserted into the first recess 59a by passing through the first insertion hole 91b, and the second insertion portion 82b is inserted into the second recess 69a by passing through the second insertion hole 92b. In this way, the hook 23b, as a second functional component, is attached to the first portion 41a and the second portion 42a by the stopper member 80b.

[0070] Figure 27 is a schematic perspective view showing the hanger pole 24b as a second functional component attached together with the mounting fixture 40b. Referring to Figure 27, the hanger pole 24b includes a second ring-shaped portion 36b whose length in the X direction is longer than its length in the Y direction, and a second support portion 37b that supports the second ring-shaped portion 36b.

The first insertion hole 94b and the second insertion hole 95b are spaced apart in the X direction.

[0071] The hanger pole 24b is installed as follows: The first portion 41a and the second portion 42a are attached to the rod-shaped member 10b so that they are closed. Then, the second support portion 37b is placed on the first and second end faces, with the first insertion hole 94b aligned with the first recess 59a and the second insertion hole 95b aligned with the second recess 69a. Then, the first insertion portion 81b is inserted into the first recess 59a by passing through the first insertion hole 94b, and the second insertion portion 82b is inserted into the second recess 69a by passing through the second insertion hole 95b. In this way, the hanger pole 24b as a second functional component is attached to the first portion 41a and the second portion 42a by the stopper member 80b.

[0072] Figure 28 is a schematic perspective view showing the bar 25b as a second functional component mounted together with the mounting fixture 40b. Referring to Figure 28, the bar 25b includes a rod-shaped portion 38b extending in the X direction and a third support portion 39b that supports the rod-shaped portion 38b. The third support portion 39b is shaped by bending a single strip-shaped member. The third support portion 39b is provided with a first insertion hole 97b and a second insertion hole 98b, which penetrate in the Z direction, and a notch 99b. The first insertion hole 97b and the second insertion hole 98b are spaced apart in the X direction.

[0073] The installation of the bar 25b is as follows: The bar 25b is attached to the rod-shaped member 10b so that the first portion 41a and the second portion 42a are closed. Then, the third support portion 39b is placed on the first end surface and the second end surface so that the position of the first insertion hole 97b is aligned with the position of the first recess 59a and the position of the second insertion hole 98b is aligned with the position of the second recess 69a. Then, the first insertion portion 81b is inserted into the first recess 59a so as to pass through the first insertion hole 97b, and the second insertion portion 82b is inserted into the second recess 69a so as to pass through the second insertion hole 98b. In this way, the bar 25b as the second functional component is attached to the first portion 41a and the second portion 42a by the stopper member 80b.

[0074] In this embodiment, the closed state maintenance unit 44b includes a stopper member 80b having portions that are inserted into the first recess 59a and the second recess 69a. The stopper member 80b includes a rod-shaped first insertion portion 81b that can be inserted into the first recess 59a, a rod-shaped second insertion portion 82b that extends in the same direction as the first insertion portion 81b, is spaced apart from the first insertion portion 81b, and can be inserted into the second recess 69a, and a connecting portion 83b that connects one end of the first insertion portion 81b and one end of the second insertion portion 82b. Therefore, the closed state of the first portion 41a and the second portion 42a can be maintained by using the stopper member 80b. In this case, since a stopper member 80b with a relatively simple structure can be used, the configuration can be simplified and productivity can be improved.

[0075] In this embodiment, the connecting portion 83b extends in a direction intersecting the direction in which the first insertion portion 81b and the second insertion portion 82b extend. Therefore, the configuration of the stopper member 80b can be further simplified. Consequently, productivity can be further improved.

[0076] In this embodiment, the other end of the first insertion portion 81b and the second insertion portion 82b each taper towards the tip. Therefore, the first insertion portion 81b and the second insertion portion 82b can be easily inserted into the first recess 59a and the second recess 69a, respectively. Consequently, it is easier to maintain the closed state.

[0077] In this embodiment, the first insertion portion 81b and the second insertion portion 82b are both solid cylindrical shapes. Therefore, it is easy to maintain high rigidity in the first insertion portion 81b and the second insertion portion 82b. Consequently, it is easy to reliably maintain the closed state over a long period of time.

[0078] In this embodiment, the connecting portion 83b is flat. Therefore, when inserting the first insertion portion 81b and the second insertion portion 82b into the first recess 59a and the second recess 69a, respectively, and maintaining the closed state, the risk of the stopper member 80b becoming bulky in the insertion direction can be reduced. Consequently, the risk of the stopper member 80b coming off the first portion 41a and the second portion 42a can be reduced, and the appearance can be improved.

[0079] In this embodiment, a second functional component is attached to the first part 41a and the second part 42a. The second functional component includes at least one of the following: a panel 21b, a table 22b, a hook 23b, a hanger pole 24b, and a bar 25b. Therefore, by utilizing the second functional component attached to the first part 41a and the second part 42a, user convenience can be improved.
