Description

[Detailed description of the invention] (Field of industrial application) The invention can be used to easily and easily form bench seats, table tops, etc. suitable for installation in parks and stadiums, for example. The present invention relates to an assembly type horizontal stand that is convenient for transportation and storage.

(Prior art) For example, the sectional bench is
There are some that are disclosed in the publication.

This has a semi-circular arc shape on both front and rear edges of a horizontally long bench board, with a central part protruding outward, and the opposing ends abut against the inner surface on the pillars. A plurality of support arms are arranged in pairs in the front and back and arranged on the left and right, and pipes are fitted to connect the slightly upwardly sloping outer ends of the support arms. By setting it in a horizontal state, the pipe is brought into pressure contact with the inner surface of the curved part of the bench board, and the bench is assembled.

Another example is disclosed in Japanese Utility Model Publication No. 54-28096.

In this case, the curved front and rear edges of the seat plate, similar to the first example, are attached to both the front and rear sides of the plurality of legs using mounting brackets, and the center of the seat plate is hung from the center of each leg. It is designed to be supported by the reinforcing tubes passed over it.

(Problem to be solved by the present invention) In the first example described above, when assembling, the curved part of the bench board must be slid from one end of the pipe, so if the bench board is long, the side of the pipe It requires a large space on both sides, is cumbersome to handle, and is prone to bending or warping in the center part of the bench board after long-term use.

In the second example, due to the reinforcing tube, the central portion of the seat plate does not bend or warp, but both the front and rear curved portions tend to bend or warp.

In both cases, the front and rear widths of the seat plates are constant, so they are perfect for constructing wide benches or tables that can be seated from both the front and back.

(Means for solving the problem) The present invention includes a plurality of support arms that face in the front-rear direction, are parallel to each other, and are bent so that both front and rear ends are above the center, and the same side of the support arms. A pair of front and rear support tubes that are parallel to each other are installed between the ends of the tube, and a pair of front and rear support tubes that are horizontal and curved downward from one end in the front and back direction, with the center part protruding outward. The arcuate curved portion is fitted onto the support tube above the support arm, and the upper parts of the hanging pieces hanging from the other end are brought into contact with each other to form a horizontal plate. a split plate in which engaging pieces facing in the direction opposite to the arcuate curved portion and tilted upward are provided at the lower end of the recessed portion facing the arcuate curved portion connected to the lower end and are opposed to each other in close proximity to each other; The above-mentioned problem is solved by having a horizontal base formed by a fastening fitting that extends over the joint piece from above and overlaps with the other, and a fastening member that fastens the fastening fitting to the support arm.

(Function) In the horizontal table of the present invention, after assembly, the hanging pieces and locking pieces provided on the dividing plate that also serve as reinforcement, as well as the support tubes that engage with the curved parts, prevent the horizontal plate from bending or warping. To prevent.

In addition, since the horizontal plate is divided into two parts at the center, by tilting the dividing plate and engaging the diagonally downward curved part with the support tube, and then making the dividing plate horizontal, on the support arm, Horizontal plates can be easily installed.

Furthermore, by providing a suitable foot or the like on the lower surface of the support arm, the horizontal table can be made to a desired height, and by providing an auxiliary plate between the two dividing plates, the front and rear width of the horizontal plate can be increased. I can do it.

(Example) Figures 1 and 2 show the horizontal platform of the present invention being placed on the stepped concrete base of the stadium.
This shows an example of forming a bench.

Anchor bolts 2 are mounted on the base 1, facing in the front-rear direction and lining up laterally.
A plurality of mutually parallel support arms 3 are fixed.

The support arm 3 has a central piece 3a fixed to the base 1.
, an inclined piece 3b that goes outward and upward from both the front and rear ends (right and left in FIG. 2), and a horizontal piece 3c that goes outward from the outer end. A support tube 4 is fixed to the end.

Reference numeral 5 denotes an oblong horizontal plate, which is divided into front and rear dividing plates 6 at the center in the front-rear direction.

At the front edge of the dividing plate 6 at the front (left side in Figure 2),
A curved part 6a having a semi-circular arc shape and a central part protruding forward is formed, and a hanging piece 6b whose lower part is recessed 6d in the direction of the curved part 6a is also provided at the rear edge, and a hanging piece 6b extends rearward and upward from the lower end. A locking piece 6c, which is inclined toward the front and whose tip is located slightly forward of the rear edge of the front split plate 6, is connected to the locking piece 6c.

The rear divided plate 6 is symmetrical with respect to the front divided plate 6, and the upper portions of the hanging pieces 6b of both divided plates 6 are in contact with each other.

On the upper surface of the locking piece 6c of both dividing plates 6, a fastening metal fitting 7 having an F-shaped side surface and the same width from side to side as the support arm 3 is overlapped, and a screw 8 is inserted into the center from above. is screwed onto the central piece 3a of the support arm 3, the two dividing plates 6 are drawn together, and the hanging pieces 6b come into pressure contact with each other, and both the curved parts 6a
is in pressure contact with the support tube 4.

9 is a screw 8 on the hanging piece 6b of both dividing plates 6.
This is a driver insertion hole consisting of both semicircular grooves cut above and facing in the vertical direction.

In order to place both dividing plates 6 horizontally on the support arm 3 as shown in the figure, for example, the curved portion 6a is fitted into the support tube 4 in the state in which the rear dividing plate 6 is shown,
Next, as shown by the imaginary line, the front dividing plate 6 may be tilted forward and downward, and after fitting the curved portion 6a into the support tube 4, it may be made horizontal.

Although not shown, the above-mentioned bench has support arms 3
By attaching appropriate pedestals to the lower surface of the bench in place of the base 1, it is possible to make a movable bench that is effective for use in parks and the like.

FIG. 3 shows an example in which a table is formed from the horizontal stand of the present invention, and the same members as described above are given the same reference numerals and their explanations will be omitted.

The center piece 51a of the support arm 51 shown in FIG.
is fixed with screws 54.

An auxiliary plate 55 as described below is interposed between the front and rear dividing plates 6 where the curved portion 6a fits into both support tubes 4, and a horizontal plate 56 wider than the horizontal plate 5 is formed. .

At both front and rear ends of the auxiliary plate 55, a hanging piece 55a and a locking piece 55b, which are similar to the hanging piece 6b and locking piece 6c of the dividing plate 6, are arranged in series, and the auxiliary plate 55 is at the same height as the dividing plate 6. I am doing it.

The auxiliary plate 55 is constructed by screwing a screw 58, which is inserted through the center piece 51a of the support arm 51 from below, into a tightening fitting 57 having the same shape as the above-mentioned tightening fitting 7, which overlaps the upper surfaces of the opposing locking pieces 6c and 55b. As a result, the hanging pieces 6b and 55a are attached to the support arm 51 by being brought into pressure contact with each other.

(Effects of the present invention) As mentioned above, the horizontal table of the present invention can be easily attached to the support arm even if the dividing plate is long.
Furthermore, when disassembled, the horizontal plate is divided into divided plates and becomes narrower, making it convenient for transportation and storage.

During use, both longitudinal ends and the center of the horizontal plate are reinforced by the support tube and the hanging pieces of each divided plate, so even after long-term use, the horizontal plate will not bend or warp. There is no.

Furthermore, by attaching appropriate base legs or leg rods to the underside of the support arm, or inserting an auxiliary plate between the two dividing plates, a bench or table of any height can be formed, which is extremely convenient. be.
