Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a table with shelves having shelves provided substantially parallel to each other below a top plate.

[0002]

2. Description of the Related Art Various conventional tables with shelves of this kind are known, for example, by welding a metal pipe material or a plate material to a support member which can be fixed to the lower surface of a top plate. Some are stuck due to.

[0003]

However, in the case where metal pipes and plates are assembled by welding, it takes time to manufacture the shelves and the shelves are expensive. Further, since the shelves are stocked as parts after being subjected to surface treatment such as painting after welding, the size of the parts becomes large, and there is a drawback that a large space is required in a storage place and an assembly work.

In order to solve the above-mentioned various problems, the present invention makes the parts constituting the shelves have a shape which requires a small number of processing steps and is easy to stock, so that the space for storing the parts and the space required for the assembly work are minimized. The object is to provide a table with shelves that can be limited.

[0005]

According to the present invention, the above problems can be solved as follows. (1) In a table with shelves having shelves provided substantially parallel to the bottom of a top plate, mounting portions for the top plate are provided at the upper part of a pair of left and right shelf support members having inner side surfaces open, and the opposite inner side, provided with a tube <br/> shaped receiving portion for each end of the can fitted respectively facing the lateral direction of the plurality of shelves pipes arranged in the longitudinal direction, and the rear lower part of the shelf receiving material ,Top board
When folded, it acts as a cushioning material against the impact of the top plate.
The protruding portion is formed downward.

(2) In the above item (1), the shelf support member is integrally formed of a synthetic resin material to integrally form the mounting portion and the receiving portion.

(3) In the above item (1) or (2), a reinforcing rod facing the left-right direction is attached to the lower surface of the top plate, and the rear ends of the left and right shelf supports are brought into contact with the reinforcing rod. A rearward protruding piece that can be engaged is formed.

(4) In any one of the above items (1) to (3), the rearmost receiving portion is provided slightly above, and the rearmost shelf pipe of the plurality of shelf pipes arranged in the front-rear direction is Position above other shelf pipes.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings show an example in which the present invention is applied to a folding table (A) with shelves. The table (A) is a metal leg that is erected on a leg (1) with casters. The columns (2) are arranged on the left and right, and the top plate (3) is placed between the pair of left and right pedestals (2) from the horizontal use state shown in FIG.
It is foldably mounted in the vertical unused storage condition shown in.

The shelf (5) comprises a pair of left and right shelf supports (6) and a plurality of shelf pipes (7).

The pair of left and right shelf supports (6) are integrally molded of a synthetic resin material, and the overall shape is a box-like shape with an open inner side surface. It is described as the front). A rearward projecting piece (9) is formed at the rear end of each shelf receiving material (6) slightly below the upper end. Horizontal plate of the upper end of the shelf receiving material (6) has a mounting portion (11). Rear protruding piece (9) and mounting part
Mounting holes (10) and (8) are formed at appropriate places of (11).

On the inner surface of the lower part of the shelf support material (6), each shelf pipe is
Five tubular receiving parts (12) (13) into which the ends of (7) are fitted
However, they are integrally connected from the front part to the rear part at equal intervals. The receiving part (13) at the end is the other four receiving parts (1
It is formed at a position slightly higher than 2).

On the lower part of the rear part of the shelf support material (6), there is a protrusion (14).
Are formed so as to project downward. Although the protrusion (14) has a partition wall (15) in the middle thereof, most of the protrusion (14) is substantially hollow, and when the top plate (3) is folded, as shown in FIG. It acts as a cushioning material against the impact of the top plate (3).

FIG. 2 shows the right shelf support (6) and shelf pipe (7).
The right end portion of the shelf pipe member (6) having such a structure is made to face each other so that the receiving portions (12) and (13) face each other, and the shelf pipe (7 ), Both ends can be fitted together.

To attach the shelf (5) to the lower surface of the top plate (3),
First, the upper part of the rear surface of one shelf support (6) and the rearward projectionPieceOf (9)
Attach the bottom surface to the bottom surface of the top plate (3) as shown in Fig. 3.
Abutting against a reinforcing rod (4) having a rectangular cross section facing in the left-right direction.
In the state, protruding backwardPieceMounting holes for (9) and mounting part (11)(Ten)
Screw the wood screw inserted from (8) to the reinforcing rod (4) and top plate (3).
Fix by inserting.

Then, one end of the shelf pipe (7) is fitted into each receiving portion (12) (13) of the one shelf receiving material (6), and then the other end of the shelf pipe (7) is fitted. On the other end of the shelf
The receiving parts (12) and (13) of (6) are fitted, and the other shelf receiving material (6)
Is fixed to the reinforcing rod (4) and the top plate (3) in the same manner as above.

In the folding table with shelves (A) assembled in this way, the top plate (3) is in the horizontal state shown in FIG. 1 when in use, but when not in use, it is placed in the top position as shown in FIG. The plate (3) can be folded in a substantially vertical state. In this folded state, the protruding portion of the shelf support material (5)
Since (14) projects forward from the pedestal (2), the upper surface of the top plate (3) of the table (A) that is stored adjacent to it hits the lower projecting portion (14) having a cushioning action. Therefore, the top plate (3) is not directly damaged by hitting the metal pedestal (2).

[0018]

According to the present invention, the shelf is composed of left and right shelf supports and a plurality of shelf pipes, which are simple parts with few processing steps, and can be easily assembled below the top plate simply by assembling them. Since the shelves are formed in the racks, the number of manufacturing steps of the shelves is shortened and the shelves are inexpensive. In addition, since each of the parts used has a shape that can be easily stocked, it is possible to minimize the storage space and the space required for the assembly work.

According to the second aspect of the present invention, the shelf receiving material can be easily formed and the weight thereof can be reduced.

According to the third aspect of the present invention, when the left and right shelf support members are attached to the top plate, positioning in the front-rear direction can be easily performed and the shelves are reinforced.

According to the fourth aspect of the present invention, since the load put in from the front of the shelf comes into contact with the rearmost shelf pipe, the load can be prevented from dropping backward.
