Table 10
First, the configuration of a table 10, which is one embodiment of a fixture according to the present invention, will be described with reference to Figures 1 and 2. The table 10 is mainly composed of a combination of members formed by bending steel plates or the like. In this specification, the table 10 will be used as an example of a fixture, but the present invention is not limited to tables and can be generally applied to fixtures such as cabinets and lockers that have a tabletop or shelf arranged to extend horizontally.

As shown in Figures 1 and 2, the table 10 according to this embodiment comprises two adjacent rectangular top plates 11, 11 and two rectangular side plates 12, 12 arranged parallel to each other. The side plates 12, 12 support the undersides of the opposing sides of the two top plates 11, 11. As shown in Figure 3, the top plate 11 is configured as a hollow plate-like member. In the table 10, the top plate 11 functions as an example of a "horizontally extending upper plate" according to the present invention.

The table 10 is configured so that two users can use the top plate 11 while facing each other. For this reason, of the two long sides of each top plate 11, the long side closest to the adjacent top plate 11 is located farther from the user of that top plate 11, and is therefore referred to as the "rear long side" in this specification. Similarly, of the two long sides of each top plate 11, the long side farther from the adjacent top plate 11 is located closer to the user of that top plate 11, and is therefore referred to as the "front long side" in this specification.

As shown in FIG. 2, the underside of the tabletop 11 has a number of tabletop slit holes 11s opened along the long side, which are used when providing drawers or the like in the table 10. Specifically, the tabletop slit holes 11s are opened along each of the long sides on the rear side and the long sides on the front side of the tabletop 11, with the direction perpendicular to the long sides of the tabletop 11 as the longitudinal direction.

As shown in FIG. 2, a duct 13 capable of accommodating wiring cables and the like is provided at the bottom between the tabletops 11 (between the long sides of the rear sides of each tabletop 11). The duct 13 comprises duct side plates 13a, 13a hanging downward from the long sides of the rear sides of each tabletop 11, and a duct bottom plate 13b connecting the lower ends of the duct side plates 13a, 13a. As shown in FIG. 2, a number of duct slit holes 13s are opened in the lower surface of the duct bottom plate 13b. In the table 10, the duct bottom plate 13b can also function as an example of a "horizontally extending upper plate" according to the present invention.

[Functional member 20]
1 and 2, the table 10 includes a functional member 20 attached to the bottom surfaces of the top plate 11 and the duct bottom plate 13b. In this embodiment, the functional member 20 can be attached to either the top plate 11 or the duct bottom plate 13b in the same manner. In this embodiment, the functional member 20 is made of a resin material.

As described above, a number of tabletop slit holes 11s are opened on the underside of the tabletop 11, and the periphery of any one or more of the tabletop slit holes 11s can be used as a mounting portion to which the functional member 20 is attached. As shown in Figures 1 and 2, in the table 10 according to this embodiment, the functional member 20 is configured to be attached to a tabletop slit hole 11s opened near the longitudinal center of the long side on the front side of one tabletop 11.

When the functional member 20 is attached to the underside of the duct bottom plate 13b, the periphery of one or more of the many duct slit holes 13s functions as a mounting portion to which the functional member 20 is attached. Below, the functional member 20 attached to the top plate 11 will be described with reference to Figures 3 to 8.

As shown in Figures 3 to 8, the functional member 20 has a base member 21 that engages with the top plate slit hole 11s of the top plate 11, and a hook 22, which is a functional part main body that can be attached so that its horizontal position relative to the base member 21 can be changed.

As shown in Figures 3 to 5, the base member 21 is formed by combining a base body 30 and a regulating member 40. The base body 30 is a member that supports the hook 22 with a main body portion 31 shaped like a square plate. An engagement portion 32 is formed on the top surface of the main body portion 31, extending to the opposite side to the regulating member 40. One end side of the main body portion 31 (the hook 22 side in Figure 5) is cut out to form an inserted portion 33, and a support portion 34, which is a spherical recess, is formed on the inside of the inserted portion 33.

A groove-shaped insertion groove 35 is formed on the other end side of the main body 31. Restriction protrusions 36, 36 are formed at the rear end of the insertion groove 35, protruding opposite each other. Two protruding ridges 37, 37 are formed protruding upward on the other end side of the top surface of the main body 31. As shown in Figures 7 and 8, a locking portion 38 is formed on the inner surface of the insertion groove 35, protruding toward the other end side of the main body 31.

The regulating member 40 is a member that is attached to the base body 30 and regulates the displacement of the base body 30. As shown in FIG. 5, the regulating member 40 is formed with a regulating main body portion 41, a second engagement portion 42, and an elastic piece 43. An inverted U-shaped elastic piece 43 is formed on one end side of the regulating main body portion 41 (the side of the base body 30 in FIG. 5). The elastic piece 43 is configured to be elastically deformable so as to move toward and away from the regulating main body portion 41.

The surface of the elastic piece 43 facing the base body 30 is formed with an engaged portion 44 that protrudes toward one end of the regulating member 40. As shown in Figures 7(b) and 8, the lower end of the tip side of the elastic piece 43 extends slightly from the lower end surface of the regulating body portion 41. In addition, the base end of the elastic piece 43 is formed with a regulated protrusion 45 that is widened in the width direction.

A second engagement portion 42 is formed on the upper surface of the regulating body portion 41, extending toward the other end opposite the base body 30. A curved surface portion 46 is formed on the regulating body portion 41 toward one end. Specifically, as shown in FIG. 7, the curved surface portion 46 is formed in an R-shape on the regulating body portion 41 so that it can be seen in a side view.

5, the hook 22 comprises a hook portion 22a formed in a bent hook shape, a cylindrical connecting portion 22b formed by protruding upward from the upper end surface of the hook portion 22a, and a hemispherical supported portion 22c formed at the upper end of the connecting portion 22b. The outer surface shape of the supported portion 22c is formed in a spherical shape that is substantially the same as the inner surface shape of the support portion 34 formed on the base body 30.

[Procedure for Assembly of Functional Member 20]
Next, the procedure for assembling the functional member 20 to the top plate 11 will be described with reference to Figures 6 to 8. When assembling the functional member 20 to the top plate 11, first, as shown in Figure 6(a), the hook 22 is attached to the base body 30. Specifically, as shown by the dashed-dotted arrow in Figure 6(a), the connecting portion 22b of the hook 22 is inserted into the inserted portion 33 of the base body 30, and the supported portion 22c is placed from above on the support portion 34. This causes the base body 30 and the hook 22 to engage with each other.

Then, as shown by the dashed arrow in FIG. 6(a), the engaging portion 32 of the base body 30 is inserted into the top plate slit hole 11s of the top plate 11 and slid to engage the engaging portion 32 with the top plate slit hole 11s. As a result, the base body 30 and the hook 22 are integrally assembled to the top plate 11 as shown in FIG. 6(b) and FIG. 7(a). In this state, the upward displacement of the hook 22 is restricted by the top plate 11. Also, the width dimension of the supported portion 22c of the hook 22 is larger than the dimension of the gap in which the inserted portion 33 is formed. Therefore, the hook 22 will not come out of the base body 30.

Furthermore, as shown by the dashed arrow in FIG. 6(b), the second engagement portion 42 of the regulating member 40 is inserted into the top plate slit hole 11s, and the regulating main body portion 41 is lifted toward the base main body 30 while rotating (see FIG. 7(a)). As a result, the second engagement portion 42 is inserted into the top plate slit hole 11s in the opposite direction to the engagement portion 32 of the base main body 30. At this time, by forming the curved surface portion 46 into an R-shape, it is possible to rotate the regulating main body portion 41 so that it does not interfere with the base main body 30.

When the regulating body portion 41 is rotated upward as described above, the elastic piece 43 of the regulating member 40 is inserted into the insertion groove 35 of the base body 30 (see FIG. 4). Then, the locked portion 44 comes into contact with the locking portion 38, causing the elastic piece 43 to elastically deform, and the locked portion 44 rides up the upper side of the locking portion 38. When the locked portion 44 is displaced above the locking portion 38, the elastic deformation of the elastic piece 43 is released, and the locked portion 44 is locked by the locking portion 38 as shown in FIG. 8. As a result, the regulating member 40 is assembled into the top plate slit hole 11s while being locked to the base body 30.

When the restricting member 40 is attached to the tabletop slit hole 11s, the displacement of the base body 30 is restricted by the restricting member 40, so that the engagement state between the engagement portion 32 and the tabletop slit hole 11s is maintained. In other words, the state in which the functional member 20 is engaged with the tabletop slit hole 11s can be stably maintained.

When the regulating member 40 is assembled in the top plate slit hole 11s, the regulated protrusion 45 is inserted inside the insertion groove 35 as shown in FIG. 4. The rear end of the insertion groove 35 is formed with regulating protrusions 36, 36, which regulate the displacement of the regulated protrusion 45 in the direction of coming out of the insertion groove 35. This prevents the regulating member 40 from displacing in the direction away from the base body 30, which would release the engagement between the locked portion 44 and the locking portion 38.

When removing the functional member 20 from the tabletop 11, a force is applied to the lower end of the tip of the elastic piece 43 on the opposite side of the base body 30, causing the elastic piece 43 to elastically deform. This releases the locked state of the locked portion 44 by the locking portion 38, making it possible to remove the regulating member 40 from the base body 30. After removing the regulating member 40 from the base body 30, the base body 30 and the hook 22 are removed from the tabletop slit hole 11s by sliding the base body 30 in a direction in which the engagement between the engagement portion 32 and the tabletop slit hole 11s is released.

In this embodiment, as shown by the dashed line L in FIG. 7(b), when the functional member 20 is attached to the top plate 11, the lower end of the tip side of the elastic piece 43 is configured to be aligned vertically with the lower end surface of the base body 30. This prevents other objects from getting caught on the lower end of the tip side of the elastic piece 43 while the functional member 20 is in use. In this way, in this embodiment, the restricting member 40 is prevented from coming off the base body 30 due to the user unintentionally elastically deforming the elastic piece 43.

[Function of Functional Member 20]
When the functional member 20 is attached to the top plate 11, it becomes possible to hang items used around the table 10, such as bags, small items, cables, etc., on the hook portion 22a of the hook 22. The outer shape of the supported portion 22c of the hook 22 and the inner shape of the support portion 34 of the base body 30 are formed to be substantially the same spherical shape. Therefore, the hook 22 is attached to the base body 30 so that the horizontal position of the hook 22 relative to the base member 21 can be freely changed. That is, the user of the table 10 can change the horizontal position by rotating the hook 22 depending on the usage mode of the functional member 20. This makes it possible to improve the usability of the functional member 20 on the table 10.

In addition, in this embodiment, the hook 22 is permitted to move in a direction other than horizontal rotation. Specifically, for example, if the outer shape of the supported portion 22c and the inner shape of the support portion 34 are formed in a conical shape (mortar shape), when a force is applied to the hook 22 in a direction different from the horizontal rotation (for example, a rocking direction with a horizontal axis of rotation), it is difficult for the hook 22 to smoothly displace in the direction of the force. In this embodiment, the outer shape of the supported portion 22c and the inner shape of the support portion 34 are made to be approximately the same spherical shape, so that the hook 22 can rock in a direction with a horizontal axis of rotation within the clearance range between the upper surface of the supported portion 22c and the lower surface of the attached portion on the top plate 11. Furthermore, the hook 22 can also rotate horizontally while slightly rocking.

The functional member 20 has two protruding ridges 37, 37 formed on the top surface of the main body 31, protruding upward. When a bag or the like is hung on the hook 22, the protruding ridges 37, 37 come into contact with the underside of the top plate 11, preventing the functional member 20 from tilting and suppressing rattling between the functional member 20 and the top plate 11.

As described above, the table 10 according to this embodiment is configured so that the engaging portion 32 of the functional member 20 is inserted into and engaged with the tabletop slit hole 11s. This allows the base member 21 to be stably attached to the mounting portion where the tabletop slit hole 11s is opened.

The base member 21 in the functional member 20 includes a base body 30 having an engagement portion 32, and a regulating member 40 that regulates the displacement of the base body 30 so that the engagement between the top plate slit hole 11s and the engagement portion 32 is not released. This allows the base body 30 and the regulating member 40 to be attached to the top plate 11, respectively, making it possible to easily assemble the base member 21 to the top plate 11 and improving the ease of assembly of the base member 21.

In addition, in the functional member 20, the hook 22, which is the functional part main body, is attached to the base main body 30 that has the engagement part 32. This allows the engagement part 32, which supports the weight of a bag or the like hung on the hook part 22a, to be positioned close to the hook 22. In other words, the bending moment generated in the engagement part 32 can be reduced, making it possible to stably support the hook 22.

In addition, in the functional member 20, the restricting member 40 has a second engaging portion 42 that is inserted in the opposite direction to the engaging portion 32 and engages with the tabletop slit hole 11s. This allows the engaging portion 32 and the second engaging portion 42 to maintain their engagement with the tabletop slit hole 11s even if the base member 21 is displaced relative to the tabletop slit hole 11s, making it possible to stably support the functional member 20 on the tabletop 11.

In addition, in the functional member 20, the regulating member 40 has an engaged portion 44 that engages with the engaging portion 38 of the base body 30 when combined with the base body 30. This allows the combined state of the base body 30 and the regulating member 40 to be stably maintained.

In addition, when the functional member 20 is attached to the top plate 11, the upward displacement of the hook 22 is restricted by the top plate 11, so that removal of the hook 22 from the base member 21 is restricted. This prevents the hook 22 from coming off the base member 21 when the functional member 20 is attached to the top plate 11.

[Modification]
The above embodiment can be modified as appropriate as shown in the following modifications. Each modification may be applied in combination with other modifications as long as no contradiction occurs.

The functional member according to the present invention can be attached not only to tables, but also to any other furniture with a top or shelf, such as cabinets and lockers. It is also possible to assemble the functional member to a board material that extends in the up-down and left-right directions (a board material whose thickness direction is horizontal), such as a side panel or back panel that is different from a top or shelf.

For example, as shown in FIG. 9, functional member 20A, which is a first modified example of functional member 20, can be assembled to side plate slit hole 111s, which is an engaging portion opened in side plate 111. Functional member 20A according to this modified example has a base member 121 that engages with side plate slit hole 111s, and a hook 122, which is a functional part main body that can be attached so that its horizontal position relative to base member 121 can be changed.

As shown in FIG. 9, the base member 121 is configured by combining a base body 130 and a restricting member 40. In this modified example, the restricting member 40 has the same configuration as the restricting member 40 in the functional member 20, so a detailed description will be omitted.

The base body 130 is a member that supports the hook 122 with a main body portion 131 having a rectangular column shape. An engagement portion 132 extending to the opposite side to the restricting member 40 is formed on the back surface of the main body portion 131 (the surface on the side of the side plate 111). One end side of the main body portion 131 (the lower end side on the hook 122 side in FIG. 9) is cut out to form an inserted portion 133, and a support portion 134 that is a spherical recess is formed on the inside of the inserted portion 133.

A groove-shaped insertion groove 135 is formed on the other end (upper end) of the main body 131. Restriction protrusions 136, 136 are formed at the upper end of the insertion groove 135, protruding opposite each other. Two protrusions 137, 137 are formed protruding upward on the upper end side of the back surface of the main body 131. As shown in Figure 9, a locking portion 138 is formed on the inner surface of the insertion groove 135, protruding toward the upper end side of the main body 131.

9, the hook 122 comprises a hook portion 122a formed in a bent hook shape, a cylindrical connecting portion 122b formed by protruding upward from the upper end surface of the hook portion 122a, and a hemispherical supported portion 122c formed at the upper end of the connecting portion 122b. The outer surface shape of the supported portion 122c is formed in a spherical shape that is substantially the same as the inner surface shape of the support portion 134 formed on the base body 130.

When assembling the functional member 20A to the side plate 111, the hook 122 is assembled to the base body 130 in the same manner as the functional member 20. Specifically, the connecting portion 122b of the hook 122 is inserted from the back into the inserted portion 133 of the base body 130, and the supported portion 122c is placed from above on the support portion 134. This engages the base body 130 and the hook 122.

Then, the engaging portion 132 of the base body 130 is inserted into the side plate slit hole 111s of the side plate 111 and slid downward to engage the engaging portion 132 with the side plate slit hole 111s. This causes the base body 130 and the hook 122 to be integrally assembled to the side plate 111. In this state, the side plate 111 restricts the displacement of the hook 122 towards the side plate 111. Therefore, the hook 122 will not come out of the base body 130.

The second engagement portion 42 of the regulating member 40 is then inserted into the side plate slit hole 111s, and rotated toward the base body 130 while rotating the regulating body portion 41. As a result, the second engagement portion 42 is inserted into the side plate slit hole 111s in the opposite direction to the engagement portion 132 of the base body 130.

When the regulating body 41 is rotated as described above, the elastic piece 43 of the regulating member 40 is inserted into the insertion groove 135 of the base body 130. Then, the locked portion 44 comes into contact with the locking portion 138, causing the elastic piece 43 to elastically deform, and the locked portion 44 climbs over the locking portion 138. When the locked portion 44 climbs over the locking portion 138, the elastic deformation of the elastic piece 43 is released, and the locked portion 44 is locked by the locking portion 138 as shown in FIG. 9. As a result, the regulating member 40 is assembled into the side plate slit hole 111s while being locked to the base body 130.

When the restricting member 40 is assembled into the side plate slit hole 111s, the displacement of the base body 130 is restricted by the restricting member 40, so that the engagement state between the engaging portion 132 and the side plate slit hole 111s is maintained. In other words, the state in which the functional member 20A is engaged with the side plate slit hole 111s can be stably maintained.

When the regulating member 40 is assembled into the side plate slit hole 111s, the regulated protrusion 45 is inserted into the inside of the insertion groove 135 as shown in FIG. 9. The upper end of the insertion groove 135 is formed with regulating protrusions 136, 136, which regulate the displacement of the regulated protrusion 45 in the direction of coming out of the insertion groove 135. This prevents the regulating member 40 from displacing in the direction away from the base body 130, which would release the engagement between the locked portion 44 and the locking portion 138.

The method for removing the functional member 20A from the side plate 111 is substantially the same as the method for removing the functional member 20 from the top plate 11. That is, a force is applied to the tip of the elastic piece 43 on the opposite side of the base body 130, causing the elastic piece 43 to elastically deform. This releases the locked state of the locked portion 44 by the locking portion 138, making it possible to remove the regulating member 40 from the base body 130. After removing the regulating member 40 from the base body 130, the base body 130 and the hook 122 are removed from the side plate slit hole 111s by sliding the base body 130 in a direction in which the engagement portion 132 is released from the engagement with the side plate slit hole 111s.

When the functional member 20A is attached to the side plate 111, it becomes possible to hang a bag, small items, cables, etc. on the hook portion 122a of the hook 122. The outer shape of the supported portion 122c of the hook 122 and the inner shape of the support portion 134 of the base body 130 are formed to be approximately the same spherical shape. Therefore, the hook 122 is attached to the base body 130 so that its horizontal position relative to the base member 121 can be freely changed. In other words, the user can change the horizontal position by rotating the hook 122 depending on the usage mode of the functional member 20A. This makes it possible to improve the usability of the functional member 20A.

As shown in FIG. 10, functional member 20B, which is a second modified version of functional member 20, can also be assembled to side plate slit hole 111s, which is an engaged portion opened in side plate 111. Functional member 20B according to this modified version is configured by combining hook member 230 and regulating member 40. In this modified version, regulating member 40 has the same configuration as regulating member 40 in functional member 20, so a detailed description will be omitted.

The hook member 230 is a member in which the base body 130 in the first modified example and the hook 122, which is the functional part body, are integrally formed. The hook member 230 includes a hook main body portion 231 having a rectangular column shape, an engagement portion 132 that extends on the rear surface of the hook main body portion 231 (the surface on the side of the side plate 111) opposite the restricting member 40, and a hook portion 233 that extends from the hook main body portion 231 to the opposite side of the side plate 111.

A groove-shaped insertion groove 235 is formed on the upper end side of the hook main body 231. Restriction protrusions 236, 236 are formed at the upper end of the insertion groove 235, protruding opposite each other. Two protrusions 237, 237 are formed protruding upward on the upper end side of the back surface of the main body 231. As shown in Figure 10, a locking portion 238 is formed on the inner surface of the insertion groove 235, protruding toward the upper end side of the hook main body 231.

When assembling the functional member 20B to the side plate 111, the hook member 230 is slid downward while the engagement portion 232 is inserted into the side plate slit hole 111s of the side plate 111, and the engagement portion 232 engages with the side plate slit hole 111s. This causes the hook member 230 to be assembled to the side plate 111.

The second engagement portion 42 of the regulating member 40 is then inserted into the side plate slit hole 111s, and rotated toward the hook member 230 while rotating the regulating body portion 41. As a result, the second engagement portion 42 is inserted into the side plate slit hole 111s in the opposite direction to the engagement portion 232 of the hook member 230.

When the restricting body 41 is rotated as described above, the elastic piece 43 of the restricting member 40 is inserted into the insertion groove 235 of the hook member 230. Then, the engaged portion 44 comes into contact with the engaging portion 238, causing the elastic piece 43 to elastically deform, and the engaged portion 44 climbs over the engaging portion 238. When the engaged portion 44 climbs over the engaging portion 238, the elastic deformation of the elastic piece 43 is released, and the engaged portion 44 is engaged by the engaging portion 238 as shown in FIG. 10. As a result, the restricting member 40 is assembled into the side plate slit hole 111s in a state where it is engaged with the hook member 230.

When the restricting member 40 is assembled into the side plate slit hole 111s, the displacement of the hook member 230 is restricted by the restricting member 40, so that the engagement state between the engaging portion 232 and the side plate slit hole 111s is maintained. In other words, the state in which the functional member 20B is engaged with the side plate slit hole 111s can be stably maintained.

When the regulating member 40 is assembled in the side plate slit hole 111s, the regulated protrusion 45 is inserted inside the insertion groove 235 as shown in FIG. 10. The upper end of the insertion groove 235 is formed with regulating protrusions 236, 236, which regulate the displacement of the regulated protrusion 45 in the direction of coming out of the insertion groove 235. This prevents the regulating member 40 from displacing in the direction away from the hook member 230, which would release the engagement between the locked portion 44 and the locking portion 238.

The method for removing the functional member 20B from the side plate 111 is substantially the same as the method for removing the functional member 20 from the top plate 11. That is, a force is applied to the tip of the elastic piece 43 on the side opposite the hook member 230, causing the elastic piece 43 to elastically deform. This releases the locked state of the locked portion 44 by the locking portion 238, making it possible to remove the regulating member 40 from the hook member 230. After removing the regulating member 40 from the hook member 230, the hook member 230 is slid in a direction in which the engagement between the engagement portion 232 and the side plate slit hole 111s is released, thereby removing the hook member 230 from the side plate slit hole 111s.

[Other Modifications]
In this embodiment, the configuration for assembling the functional member 20 to the top plate 11 of the table 10 has been described, but as shown in Fig. 2, the functional member 20 can also be attached to the duct 13 provided in the table 10 in the same manner as the top plate 11. Specifically, the functional member 20 can be attached by engaging the engagement portion 32 and the second engagement portion 42 with one of the many duct slit holes 13s.

In addition, the engaged portion of the fixture with which the functional member 20 engages need only be a concave shape with which the engaging portion 32 of the functional member 20 can engage, and does not need to have a hole. Even if a hole is formed, the shape does not need to be a slit as in this embodiment, and it is also possible to assemble the functional member 20 into a hole of another shape, such as a circle or a rectangle.

The functional part main body of the functional member 20 can be a member having other functions such as a storage box, a hanger, etc., in addition to the hook 22 in this embodiment. When the functional member 20 is attached to the underside of the tabletop 11, and an infrequently used item such as a helmet or disaster prevention goods is to be hung on the hook 22, the functional member 20 is attached to the tabletop slit hole 11s that opens along the long side on the rear side of the tabletop 11, and the hook 22 is oriented in a horizontal direction so that it extends to the front side of the tabletop 11, which is preferable for the user to easily hang it on while crawling under the tabletop.

On the other hand, when hanging a frequently used item such as a bag on the hook 22, it is preferable to assemble the functional member 20 in the tabletop slit hole 11s that opens along the long side of the tabletop 11 on the near side, and orient the hook 22 horizontally so that the hook 22 extends toward the user. Since the posture that is easy to use (ease of attaching and detaching a bag, etc. to the hook 22) differs by 180 degrees when the hook 22 is located to the right of the user from when it is located to the left, the usability of the functional member 20 can be improved by changing the horizontal posture of the hook 22 to one that is easy to use for the user's position.

In this way, the location where the functional member 20 is to be attached can be selected appropriately depending on the application. In addition, the horizontal position of the functional part body (hook 22) can be changed so that it is most convenient for each application.

In this embodiment, the base member 21 is configured by combining the base body 30 and the regulating member 40, but it is also possible to configure the base member as an integral unit. In other words, as long as the engagement state between the engaging portion of the base member and the engaged portion is maintained when the base member is attached to the engaged portion, the base member can be configured without being divided into the base body and the regulating member.

The functional member 20 can be configured so that the functional part main body (hook 22 in this embodiment) is assembled to the regulating member 40. Also, if the configuration is such that the displacement of the base body 30 can be regulated, the regulating member 40 can be configured so that the second engagement portion 42 is not provided. Also, the functional member 20 can be configured so that the functional part main body can be removed from the base member 21 when the base member 21 is engaged with the top plate slit hole 11s.

The functional member 20 can be designed to have a sense of moderation that allows it to stop lightly at a certain angle when changing the horizontal orientation of the functional unit main body relative to the base member 21. For example, it is possible to form recesses and protrusions at predetermined angles (60 degrees, 90 degrees, 120 degrees, etc.) on the outer surface of the supported portion 22c and the inner surface of the support portion 34, and to configure the protrusions to be inserted into the recesses at those angles. This makes it easier to keep the horizontal orientation of the functional unit main body relative to the base member 21 in a predetermined position.

The functional member 20 can be configured to change the horizontal orientation of the functional body, and also to allow displacement in a direction intersecting the horizontal direction (swing displacement). For example, if the gap between the upper surface of the supported portion 22c and the lower surface of the tabletop 11 is made larger than in this embodiment, the hook 22 can be swung in the front-to-rear direction (longitudinal direction of the tabletop slit hole 11s) as seen by the user. Furthermore, if the opening shape on the lower side of the support portion 34 is made larger, the hook 22 can be swung in all directions.
