By providing a base shelf, the rear end of which is substantially the same as or slightly narrower than the space between the inner surfaces between the two columns, the rear end is fitted between the two columns, and the base shelf is erected. The lower end of the rear piece hanging down from the rear end of the base shelf is engaged with the front upward bent piece continuously connected to the lower end of the hanging piece hanging down along the front surface of the connecting rod in the locking tool straddling the rod. Let it.

(2) In the above item (1), a concave groove is provided on the upper surface of the connecting rod so as to face in the left-right direction, and the locking tool is fitted over the upright wall of the connecting rod in front of the concave groove.

(3) In the above item (2), the lower end of the back plate provided between the two columns is fitted into the concave groove of the connecting rod, and the front surface of the back plate and the front inner surface of the concave groove are engaged with each other. Hold the hanging piece behind the fastener.

(4) In the above item (1), a concave groove facing the left and right direction is provided on the upper surface of the connecting rod, and a concave portion which fits into the concave groove is provided on a horizontal piece on the upper part of the locking tool. The lower end of the back plate from above.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a merchandise display shelf (1) to which the present invention is applied. In the center of each of the pillars, rectangular pillars (3) and (3) are erected, and upper ends and lower ends of both pillars (3) and (3) are respectively connected to an upper connecting rod (4) facing left and right. ) And the lower connecting rod (5) are connected to each other, and a concave groove (6) is formed in the center of the upper surface of the lower connecting rod (5) so as to extend in the left-right direction over the entire length.

FIG. 3 shows important portions of the opposing surfaces of the columns (3) and (3).
A vertical support plate (8) is fitted into the concave groove (6) and both the support members (7) and (7). Has been supported.

A large number of vertically long locking holes (9) are formed on both front and rear surfaces of the columns (3) and (3). On both front and rear sides, a shelf for merchandise display is erected in multiple stages up and down with brackets whose rear ends are locked in right and left locking holes (9).
(3) On the front and rear legs (2) and (2), the base shelf
(10) is supported as follows.

As shown in FIGS. 1 and 5, the front base shelf 10 has a thin rectangular box shape with an open lower surface.
(3) A rectangular notch (11) is cut out at both rear corners in contact with (3), so that the rear end is almost the same as the space between the inner surfaces of the left and right columns (3) and (3). Or slightly narrower. The rear base shelf (10) has the same shape as the front one, which is symmetrical in the front-rear direction.

FIG. 4 shows a locking device (12) for locking the base shelf (10) to the lower connecting rod (5).
Horizontal pieces (12c) with the upper ends of two long and short hanging pieces (12a) (12b)
The upper part of the lower connecting rod (5) has a downward U-shape that can fit over the upright walls (5a) and (5b) forward and rearward of the concave groove (6) without gaps. A downwardly bent piece (12d) is connected to the lower end of the hanging piece (12a).

The vertical length of the long hanging piece (12a) is
The height from the upper surface of the leg rod (2) to the upper surface of the lower connecting rod (5) is substantially equal, and the vertical length of the short hanging piece (12b) is substantially equal to the depth of the concave groove (6). It is good to keep.

The front base shelf (10) has two notches (11) and (11).
Is fitted to the inner corners in front of the columns (3) and (3), so that the rear end is fitted between the columns (3) and (3).
The lower end of the rear piece (10a) placed on the leg (2) (2) in front of the two posts (3) (3) and hanging down from the rear end of the base shelf (10) is connected to the lower connecting rod. The front of the lower connecting rod (5) of the locking tool (12) having one at the center and two or three or more on both sides, which is fitted over the upright wall (5a) in front of (5) from above. By engaging with the bent piece (12d) provided at the lower end of the hanging piece (12a) hanging down, the left and right leg rods (2) (2)
And is immovable in the left-right direction.

The rear base shelf (10) has a structure which is symmetrical with the front one, and has both legs (3) and (3) behind the two columns (3).
(2) It is installed on (2).

As shown in FIG. 2, when the stopper (12) is fitted over the upright wall (5a) of the lower connecting rod (5), its short hanging piece
When the (12b) is sandwiched between the front and rear side surfaces of the back plate (8) fitted into the concave groove (6) and the inner surface of the concave groove (6), the locking device
(12) does not easily come off from the lower connecting rod (5).

The upper surface of the lower connecting rod (5) is connected to the two leg rods (2) and (2).
It is desirable to match the upper surface of the base shelf (10) erected on the base.

FIG. 6 shows a modification of the locking device. This locking tool (13) connects the upper ends of two long and short hanging pieces (13a) (13b)
A horizontal piece (13c) approximately the same as the front and rear length of the lower connecting rod (14)
And a bent piece (13d) folded in a U-shape is continuously provided at the lower end of the elongated hanging piece (13a).

Since the locking member (13) uses the upper downward U-shaped portion over the entire lower connecting rod (14), it is used as in the lower connecting rod (13) of the above-described embodiment. Recessed groove (6)
It is most suitable for the case where the lower connecting rod (14) having no support is used or the case where the back plate (8) is not provided. Note that the same members as those in the above-described embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted (the same applies to the modification illustrated in FIG. 7).

FIG. 7 shows another modification of the locking device. This locking device (15) is a short hanging piece (1) of two front and rear locking devices (12) (12) which are symmetrical to each other as shown in FIG.
2b) Same as the lower end of (12b) connected with a horizontal piece (15e). (15a) and (15b) are the above-mentioned hanging pieces (12
b) A long and short hanging piece corresponding to (12b), (15c) is a horizontal piece corresponding to the horizontal piece (12c), and (15d) is a bent piece (12
This is a bent piece corresponding to d).

The engaging member (15) is fitted into the lower connecting rod (5) having the concave groove (6) from above, and the front and rear short hanging pieces (15) are fitted.
b) A recess (16) formed by (15b) and a horizontal piece (15e)
When the lower end of the back plate (8) is fitted inside, there is an advantage that the locking tool (15) does not come off from the lower connecting rod (5).

[0024]

According to the first aspect of the present invention, there is no need to perform special processing on the base shelf, and the base shelf can be shared with other shelves, so that the manufacturing cost can be reduced.

Further, after the locking member is locked to the connecting rod, the base shelf can be easily mounted on the leg rod only by placing the base shelf on the leg rod, and the rear piece of the base shelf can be engaged. When engaging the bent piece of the stopper, the bent piece can be seen from above, the base shelf is almost horizontal, the notch abuts and the lower piece is locked simply by lowering it Since it is engaged with the bent piece of the tool, the assembling work is easy.

According to the second aspect of the present invention, the entire merchandise display shelf is symmetrical with respect to the center in the front-rear direction of the support column and the connecting rod, and the merchandise can be displayed on both front and rear sides. In addition, there is an advantage that the front and rear base shelves and the locking tool can be detached independently of each other.

According to the third aspect of the present invention, the hanging piece at the rear of the locking tool is sandwiched between the back plate and the inner surface in front of the groove, so that the locking tool is less likely to come off the connecting rod.

According to the fourth aspect of the present invention, the locking member is pressed by the back plate so that it does not come off the connecting rod, and the structure becomes strong.
