[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support mechanism used when a cross bar, a handle, a shelf, or the like is attached to a column.

[0002]

2. Description of the Related Art FIG. 9 is a perspective view showing an example of an assembly type shelf. In FIG. 9, reference numeral 11 is a support, and reference numeral 12 is
The shelf plate attached to the column 11, the reference numeral 13
Are cylindrical bodies provided at the corners of the respective sections. Shelf board 12
Is attached to the column 11 by passing the column 11 through the cylindrical body 13 and supporting the cylindrical body 13 on the column 11 via a sleeve 14 (see FIGS. 11 and 12) mounted on the column 11. Have been.

As shown in FIG. 10, a shelf plate 12 is formed by connecting a rectangular upper frame 15 and a lower frame 16 so as to be vertically separated from each other by a substantially corrugated reinforcing wire 17. , 16 are connected to a cylindrical body 13. Also, wires 18 and 19 are laid on the upper frame 15 so as to be orthogonal to each other.
The wires 18 and 19 enable the article to be placed on the shelf 12. On the other hand, on the surface of the support 11, a plurality of grooves 20 around the support 11 are formed at equal intervals along the longitudinal direction of the support 11.

[0004] As shown in an exploded view in FIG. 11, the sleeve 14 is composed of sleeve halves 14A and 14B each having a semi-cylindrical shape. These sleeve halves 14A, 14B
Before being mounted on the support 11, it is divided into two parts, and when mounted on the support 11, the support 11 is sandwiched from both sides to be assembled into a cylindrical shape. Also, the sleeve half 14A, 1
4B, opposite sleeve ends 14A, 14B
When assembling is performed, an engaging projection 14a and an engaging recess 14b are formed, respectively, for engaging with each other to restrict a displacement between the sleeve halves 14A and 14B.

Further, on the inner surfaces of the sleeve halves 14A and 14B, there are formed protruding ridges 14c which engage with the grooves 20 of the column member 11. In addition, the outer peripheral surface of the sleeve 14 is shown in FIG.
As shown in FIG. 2, it is formed in a conical shape whose diameter increases from one end to the other end. That is, in FIG.
If the outer diameter of the sleeve 14 is d0, the outer diameter of one end of the sleeve 14 is d1, and the outer diameter of the other end is d2, then (d0 <d1 <d2).

The cylindrical body 13 is a cylindrical member having a through hole 13A at the center. The inner peripheral surface of the through hole 13A corresponds to the outer peripheral surface of the sleeve 14 as shown in FIG. It is formed in a tapered shape whose diameter increases from the frame 15 side) to the other end (the lower frame 16 side). That is, the inside diameter of one end of the through hole 13A is d1, and the inside diameter of the other end is d2.

When assembling the shelf having the above structure, first, at the position where the shelf plate 12 is to be mounted, the column 11 is sandwiched between the sleeve halves 14A and 14B from both sides, and as shown in FIG. The sleeve 14 is mounted on the support 11 by engaging the ridge 14c with the support 11. As a result, the movement of the sleeve 14 along the longitudinal direction of the column 11 is prevented by the engagement between the ridge 14 d and the groove 20.

Next, one end of the sleeve 14 and the cylindrical body 1
The support 11 is inserted into the through hole 13A so that the other end of the support 3 faces the other end.
Is inserted, the support 11 is erected so that one end of the sleeve 14 faces upward, and the cylindrical body 13 and the shelf 12 are slid downward as shown by the arrow S in FIG. Here, since the inside diameter of the other end of the through hole 13A is d2 and the outside diameter of one end of the sleeve 14 is d1, when the tubular body 13 is moved downward, one end side of the sleeve 14 enters the through hole 13A. . However, since the outer peripheral surface of the sleeve 14 has a conical shape whose diameter increases toward the other end, and the inner peripheral surface of the cylindrical body 13 also corresponds to the outer peripheral surface of the sleeve 14, the inner peripheral surface of the cylindrical body 13 At the position where the outer peripheral surface of
Further downward movement of the tubular body 13 is prevented.

In this state, since the sleeve 14 is pressed inward from the cylindrical body 13 side, the ridge 14d is formed.
And the groove 20 are more strongly engaged. As a result, the tubular body 13 is supported at a desired position on the support 11 via the sleeve 14.

This operation is performed almost simultaneously with the cylindrical body 13 provided at the corner of the shelf 12, so that the lowermost shelf 12 is attached to the column 11. Further, the same operation is repeatedly performed, and the shelves 12 are attached to the columns 11 sequentially from the lower side, whereby a shelf as shown in FIG. 9 is completed.

[0011]

By the way, in this type of shelf, after assembling, some of the columns 11 are attached to a member such as a crossbar, a hanger rail, a handle, a small shelf, or a hook (hereinafter referred to as a hook). In some cases, the “assisting member” is attached using the tubular body 13 and the sleeve 14. However, in order to attach the tubular body 13 to the column 11 on which the shelf board 12 is attached above, it is necessary to remove all the shelf board 12 and the sleeve 14 above the attachment position. However, there is a problem that the operation is time-consuming and time-consuming.
Further, the same problem occurs when the auxiliary member once attached is removed or when the attachment position of the auxiliary member is changed.

The present invention has been made in view of the above-described problems, and has a support 11 on which a shelf plate 12 and the like are mounted.
It is an object of the present invention to enable easy and quick attachment and detachment of the auxiliary member having the tubular body 13 to and from the vehicle.

[0013]

According to the present invention, the following technical measures have been taken to achieve the above object. That is,
The present invention includes a sleeve formed in a conical shape whose outer peripheral surface increases in diameter downward, and a cylindrical body whose inner peripheral surface is formed in a tapered shape corresponding to the outer peripheral surface of the sleeve. A support mechanism for supporting the tubular body on the pillar via the sleeve by fitting the tubular body into the sleeve from above after mounting on the pillar, wherein the tubular body includes the A slit having a width larger than the outer diameter of the column and smaller than the maximum outer diameter of the sleeve is provided at both ends of the cylindrical body.
