【Example】

Embodiment 1 FIG. 1 is an external perspective view showing the whole, FIG. 2 is an enlarged sectional view of a main part, FIG. 3 is a side view of one part of a load support, FIG. 4 is a perspective view of a fixture, and FIG. FIG. In the drawing, reference numeral 1 denotes a lower runner having a substantially U-shaped cross section mounted on a floor (not shown) in a substantially horizontal state, and 2 denotes a pair of horizontal runners mounted on the lower runner 1 at a predetermined interval. It is a vertical support having an L-shaped cross section, and its support surface 3 is provided with two rows of front and rear mounting holes 4 and 5 for detachably fixing a fixture 7 described later. Note that the height positions of the front-row mounting hole group 4 and the rear-row mounting hole group 5 are shifted by about 20 degrees so that the front-row mounting hole group 4 is located in the upper row.

Reference numeral 6 denotes an upper runner having a U-shaped cross section that connects the upper ends of the pair of columns 2. Reference numeral 7 denotes a cylindrical metal fixture whose outer surface and inner surface are substantially rectangular, and a pair of holes 73 and 74 through which fasteners 8 such as bolts penetrate are provided in an upper side 71 and a lower side 72 thereof. Have been. The holes 73 in the front row of the fixture 7 are fixed to the mounting holes 4 in the front row of the support 2, and the holes 74 in the rear row are fixed to the mounting holes 5 in the rear row of the support 2 by the fasteners 8.

In this manner, the fixture 7 is arranged such that the front end opening 75 thereof is higher than the rear end portion 76,
The support 2 is mounted obliquely at an arbitrary height at an angle of α ≒ 20 degrees with respect to a horizontal line. Experiments have confirmed that setting the mounting angle α of the fixture 7 to about 20 degrees is optimal in terms of both the workability of inserting the load support 9 described below and the effect of preventing falling off.

Reference numeral 76 denotes a flat portion formed at the front end protruding portion of the upper side 71 of the fixture 7, and 77 denotes a lower side 7 of the fixture 7.
2 is an arc-shaped notch formed in the front end projection 77A. By providing the flat portion 76 and the cutout portion 77 at the front end of the fixture 7, the decorative plate 1
It is possible to improve the appearance by reducing the diameter of the insertion slot 13 as much as possible.

Reference numeral 9 denotes a metal load supporting member having a substantially rectangular cross section and processed into a substantially rectangular shape. The load supporting device includes a horizontal portion 91 on which a shelf plate 10 made of glass or the like is mounted, and a rear end of the horizontal portion. A rod-shaped engaging portion 92 which is inserted into the hollow hole 78 of the fixing device 7 through a minute gap (0.5 to 1 mm) so as to be removable therefrom, and a horizontal portion 91. A cylindrical aluminum spacer 94 is provided over the outer periphery of the spacer through a square hollow hole 93, and a steel circular pipe-shaped load receiving portion 95 is press-fitted to the outside of the spacer.

When the load support 9 is attached to the fixture 7, the locking portion 92 is fixed with the load receiving portion 95 slightly raised from the horizontal position (slightly raised from FIG. 2). When linearly inserted into the hollow hole 78 of the tool 7,
Since the locking portion 92 and the hollow hole 78 are in a parallel state, the locking portion 92 can be inserted through a slight gap without any resistance.

When the hand is released in the inserted state, the load support 9 is lowered by its own weight, so that the rear upper edge 92A and the front lower edge 92B of the locking portion 92 are located on the inner surface of the hollow hole 78 of the fixture 7. The state is maintained by contact (state of FIG. 2).
Therefore, even if the column 2 vibrates in this state, the load support 9 does not fall off due to the frictional force between the locking portion 92 and the hollow hole 78, and is maintained in a horizontal state. The load support 9 is inserted such that the locking portion 92 is inserted into the hollow hole 78 and the hand is released (contact with the hollow hole 78 by its own weight) so that the load receiving portion 95 is substantially horizontal. Locking part 92
And the bending angle β of the load receiving portion 95 is set to about 161 degrees.

Reference numeral 11 denotes a hanger pipe integrally fixed to the load receiving portion 95 of the pair of lower load supports 9, and 12 denotes a decorative plate (partially cut away) attached to the front surface of the column 2. The front end flat 7 of the fixture 7 is inserted into the insertion opening 13.
6 and the protrusion 77A penetrate. The decorative board 12
The lower end edge 13A of the insertion opening 13 has a curved surface corresponding to the arc-shaped notch 77 of the fixture 7.

When the load support 9 is attached to the fixture 7, the locking portion 92 is held with the load receiving portion 95 slightly raised from the horizontal position (slightly raised from the state shown in FIG. 2). When the fixing member 7 is inserted into the hollow hole 78, the locking portion 92 and the hollow hole 78 are in a parallel state.
Can be easily inserted through a small gap.

If the user lifts his / her hand in the inserted state, the load support 9 tilts counterclockwise due to its own weight.
2, the rear upper edge 92A and the front lower edge 92B come into contact with the inner surface of the hollow hole 78 of the fixture 7 and are kept in that state (FIG. 2).
State).

Therefore, even if the support 2 vibrates in this state, or if the load support 9 is pulled out horizontally, the load support 9 falls off due to the frictional force between the locking portion 92 and the hollow hole 78. However, it is held in a horizontal state while being locked by the fixture 7. When the load support 9 is removed, the load support is slightly lifted and pulled forward, so that the locking portion 92 is parallel to the hollow hole 78 and can be easily pulled out without resistance.

Embodiment 2 FIG. FIG. 6 is a perspective view showing a load support 9 according to another embodiment of the present invention. According to this embodiment, the feature is that the load receiving portion 95 of the load support 9 is formed in a square shape.

Embodiment 3 FIG. 7 and 8 are cross-sectional views showing a fixing tool 7 according to another embodiment of the present invention and an attached state thereof. According to this embodiment, the notch 77 is formed only in the front end projection 77A of the lower side 72 of the fixture 7, and the upper side 71
No flat portion is formed on the protruding portion of FIG.
Although the insertion opening of the decorative board 12 is larger than that of the embodiment, the load resistance against the load supporting member 9 is increased, and the apparatus is suitable for a heavy-weight supporting device.

In the above-described embodiment, the load support 9 has the rod-shaped locking portion 92 and the load receiving portion 95 formed as separate components, but may be formed integrally .

[0022]

According to the present invention, there is provided a rod-shaped support for a load supporting member having a square cross-section, which is formed at a rear end of a load receiving portion at an inclined angle in a hollow hole of a fixing device which is attached to a support at an angle. Since the stop is configured to be inserted and removed linearly through a minute gap, after the load support is attached to the fixture, the load support is locked to the fixture by its own weight. In addition, by slightly lifting the load support, the load support can be easily pulled out of the fixture, which has an effect of being excellent in assembling workability and disassembling workability.

Further, since the locking portion of the load supporting device inserted into the hollow hole of the fixing device has a rod shape, there is also an effect that sufficient strength to withstand a load can be obtained.

Further, since it is not necessary to apply a special claw or the like to the rod-shaped locking portion, there is also an effect that the rod-shaped locking portion can be processed at low cost.
