However, in order to securely fix the connecting member and the seat plate, many screws, etc. are required, and
In order to withstand large loads, the number of reinforcing members increases, resulting in a large number of parts.
The drawbacks were that it took time to assemble and was expensive.

This invention was made in order to eliminate the above-mentioned drawbacks, and the purpose is to provide a bench that has a small number of parts, can be lowered in price, and is easy to assemble.

This invention will be explained in detail below with reference to the drawings.

FIG. 1 is an assembled perspective view of a bench that is an embodiment of this invention.

A bench that is an embodiment of this invention includes a cylindrical body 1 forming a seat part, a waist part 2, and a pair of block parts 33 connecting the seat part 1 and the leg parts 2.
It is comprised of a tightening tool 4 that tightens and integrates a pair of block parts and a seat part.

As shown in FIG. 1, the seat part is a cylindrical body 1 made of synthetic resin, which has an inner diameter d that is approximately the same as the outer diameter of the empty cans, and which houses a plurality of empty cans (not shown) in a row. It is composed of multiple wires strung across the block section. The length l of the cylindrical body 1 is an integral multiple of the length of the empty can in the axial direction, and there are a plurality of empty cans inside the cylindrical body 1 from one end opening to the other end opening. It's packed tightly. Therefore, the can lid of the empty can inside the cylindrical body 1 serves as a reinforcing member against loads applied from a direction orthogonal to the longitudinal direction of the cylindrical body 1.

As shown in Fig. 1, the legs are made of four synthetic resin containers that have an inner diameter d that is almost the same as the outer diameter of the empty cans, and which house a plurality of empty cans (not shown) in a row inside. It is composed of a bottom cylindrical body 2. Bottomed cylindrical body 2
The length L is an integral multiple of the length of the empty can in the axial direction, and is adjusted to an appropriate length that provides a comfortable sitting position on the bench. A plurality of empty cans (not shown) are tightly packed inside the bottomed cylindrical body 1 from the bottom of the bottomed cylindrical body 1 to the opening. Therefore, the circumferential side of the empty can inside the bottomed cylindrical body 1 and the can lid serve as reinforcing members against the load from the top in the longitudinal direction of the bottomed cylindrical body 2, thereby preventing buckling of the legs. Become.

The block part 3 is formed into a substantially L-shaped cross section by a horizontal part and an upright part, and has a cylindrical body 1 and a bottomed cylindrical body 2.
A pair of leg insertion portions 3A arranged at a predetermined interval, and a plurality of leg insertion portions, for example, 5
Five cylindrical body receiving parts 3B are arranged in parallel on the floor to bridge the cylindrical body 1 of the book, and support so that both ends of the cylindrical body 1 do not spring up when a load is applied to the seat part. 5 cylindrical body insertion portions 3C. The leg insertion portion 3A has an inner diameter that is approximately the same as or slightly smaller than the outer diameter of the bottomed cylindrical body 2, and is provided with an opening 3D on the lower surface into which the bottomed cylindrical body 2 is inserted, and an empty can (not shown) can be inserted into the leg insertion portion 3A. Stowed bottomed cylindrical body 2
By inserting the upper opening of the cylindrical body 2, the bottomed cylindrical body 2 can be tightly fitted. Therefore, once the bottomed cylindrical body 2 is tightly fitted into the leg insertion part 3A, the bottomed cylindrical body 2 does not easily fall off from the leg insertion part 3A. The depth of insertion of the bottomed cylindrical body 2 into the leg insertion part 3A is such that the bottomed cylindrical body 2 falls off due to friction between the outer peripheral surface of the inserted bottomed cylindrical body 2 and the inner peripheral surface of the leg insertion part 3A. In addition, it can be determined as appropriate so that the bottomed cylindrical body 2 can be held so that the bottomed cylindrical body 2 does not buckle at the insertion portion against a load from above. Cylindrical body receiving part 3B
is provided on the horizontal surface of the block portion,
It may have any shape as long as it can receive and support the cylindrical body 1, but for example, in the case of the one shown in FIG. 1, the cylindrical body receiving parts 3B1, 3B5
is a concave plate (notch) 3E cut out semicircularly so as to have the same diameter as the outer diameter of the cylindrical body 1, and the cylindrical body 1.
The cylindrical body 1 is supported by the opening 3F having the same inner diameter as the outer diameter of the cylindrical body 1, and the cylindrical body receiving parts 3B2 and 3B4
The cylindrical body 1 is supported by a plate-like body 3G cut out in a quarter-circular shape so as to have the same outer diameter as the outer diameter of the cylindrical body 1, an opening 3F, and a concave surface 3H having the same diameter as the outer diameter of the cylindrical body 1. The body receiving portion 3B3 supports the cylindrical body 1 with a concave surface 3I having the same diameter as the outer diameter of the cylindrical body 1. Moreover, a groove 3J for inserting a tightening tool is provided at the bottom of the cylindrical body receiving parts 3B2 and 3B4 from the end to the opening 3F. The cylindrical body insertion part 3C is provided inside the upright part of the block part, has a box shape as a whole and has an opening 3F, and by inserting the cylindrical body 1 into the opening 3F, it can be inserted into the seat part. This prevents the end of the cylindrical body 1 from jumping up due to such a load, and also hides the end of the cylindrical body 1.

The fastener 4 includes, for example, a metal rod such as a reinforcing bar 4C having a flange 4A at one end and a bolt 4B at the other end, and a nut such as a thumbscrew 4D that is screwed into the bolt 4B, and has a pair of block portions 3C. By inserting the reinforcing bar 4C into the groove 3J and screwing the thumbscrew 4D into the bolt 4B, the end face of the spanned cylinder 1 is connected to the rear wall surface (block) of the cylinder insertion part 3C provided in the block part 3. 3 back plate)
The two are tightened when they are in contact with each other.
In the drawing, two fasteners 4 are arranged at a predetermined interval.

Next, the assembly of the bench having the above configuration will be explained.

First, five cylindrical bodies 1 and four bottomed cylindrical bodies 2
Then, two block parts 3, two sets of tightening tools 4, and a plurality of empty cans (not shown) are prepared. Next, a plurality of empty cans (not shown) are housed in each cylindrical body 1 from the opening at one end to the opening at the other end. Also,
Each bottomed cylindrical body 2 also stores a plurality of empty cans (not shown) from its bottom to its opening. The two block parts 3 are arranged at a predetermined interval so that the cylindrical body receiving parts 3B face each other, and the reinforcing bars 4
C is inserted into the groove 3J of the block portion 3, and the flange 4A is locked at one end of the groove 3J, as shown in FIG. Note that the bolt 4B of the reinforcing bar 4C that is inserted into the groove 3J of the other block 3 still has a thumbscrew 4D.
Leave them unscrewed. Next, one end of the five cylindrical bodies 1 for storing empty cans is inserted into each cylindrical body insertion part 3C of the block part 3, and the outer periphery of the end of the five cylindrical bodies 1 is placed on each cylindrical body receiving part 3B. place By inserting the other end of each cylindrical body 1 into each cylindrical body insertion part 3C of another block part 3 and placing the outer periphery of the end of each cylindrical body 1 in each cylindrical body receiving part 3B of another block part 3. , five cylindrical bodies 1 are bridged over block parts 3 disposed opposite to each other. Thereafter, the thumbscrew 4D is screwed into the bolt 4B of the reinforcing bar 4C which has already been inserted into the groove 3J of the opposing block portion 3. When tightened with thumbscrew 4D, as shown in Figure 2,
Both end surfaces of the cylindrical body 1 are pressed by the back plate 3K of the block part 3, and the five cylindrical bodies 1 and the pair of block parts 3

Prevented. Moreover, since the end of the cylinder 1 is inserted and held in the cylinder insertion part 3C of the block part 3 and is in contact with the upper wall surface thereof, the end of the cylinder 1 can be inserted with the cylinder receiving part 3B as a fulcrum. The generated upward load is dispersed and eliminated by the cylindrical body insertion portion 3C, and even if a person sits on the seat, the end of the cylindrical body 1 is prevented from jumping up. In addition, the load applied to the seat part is
It is dispersed by B, and finally by four legs. In that case, the block part 3 comrades are connected to the cylindrical body 1.
Since the leg parts 2 are firmly connected by the two fasteners 4 while being held in place, even if a load is applied to the legs 2, no lateral sway occurs at all. Further, the cylindrical body 1
Both of the cylindrical body 2 serving as the leg portions are reinforced by the lid and the peripheral side of the empty can, and the cylindrical body can be prevented from buckling.
