Description

[Detailed explanation of the idea] The present invention relates to a bench seat assembly device.

In other words, the bench can be easily assembled by horizontally stacking the seats, which are integrally molded so that the seat and back are continuous, and if one of the seats is damaged, it can be easily replaced, and the bench is sturdy. Moreover, it can be made into a compact structure, easy to manufacture, and suitable for implementation.

Next, the embodiment shown in the drawings will be described.

Fig. 1 shows a perspective view of a part of the bench, and A is a seat, which is formed into a substantially L shape with a constant thickness so that the seat part 1 and the back part 2 are connected, and the front side of both sides of the seat part 1 and the Recesses 3 having a rectangular cross section and a constant depth are formed on both sides of the upper side of the back part 2, and are formed narrowly so that even several sheets A have the width for one person. It is also possible to form the sheet A to be wide enough to accommodate one person.

A front pipe 4 is provided on the lower side of the seat part 1 of each seat A.
, rear pipes 4 are arranged horizontally on the lower side of the back part 2, but both pipes 4,
4, each of which can be slidably fitted into the sheet A.
The support pipes 8, 8, each having the same length as the width of the support pipes 8 and 8, are integrally connected to each other.

Reference numeral 5 designates a lower support frame plate, which is formed so that it can come into contact with the lower surface of the sheet A and has the same length as the width of the sheet A. Side plate portions 5a, 5a are bent in the same way so as to be perpendicular to both ends thereof. Holes 9, 9 that can be slidably fitted into the pipe 4 are formed, respectively.

Reference numeral 6 denotes a side support frame plate, which is formed higher than the side plate portion 5a of the lower support frame plate 5, and has a short bent portion 6a formed at a right angle at its upper end to fit into the recess 3 of the sheet A. A hole 10 into which the pipe 4 can be slidably fitted is formed in the lower part.

Reference numeral 7 denotes a side support frame plate, which is formed to have the same height as the frame plate 6 and has a hole 11 at its lower part;
A bending section 7 similar to the bending section 6a is provided on both sides of the upper end.
Form a and 7a into a T-shape. 12 is a cap, and the end of the cap 12 that can be fitted into the end of the pipe 4 has a flange 12 having a diameter larger than that of the pipe 4.
form a.

Therefore, the side support frame plates 7 and the lower support frame plate 5 are alternately fitted to both pipes 4, 4 in order, the bent portion 7a of the side support frame plate 7 is fitted into the recessed portion 3 of the sheet A, and the upper surface of the lower support frame plate 5 is abutted against the lower surface of the sheet A, the support pipe 8 of the support leg B is fitted between the side support frame plates 7, 7 or between the side support frame plates 7 and 6 in the intermediate or end portions of both pipes 4, 4, the bent portion 6a of the side support frame plate 6 which fits into one end of the pipes 4, 4 is fitted into the recessed portion 3 on the outer side of the sheet A at one end,
When a cap 12 is fitted to the outer end of the side support frame plate 6 so that the flange portion 12a can support the side support frame plate 6, assembly can be completed as shown in Figs.

In this state, both the pipes 4, 4 are supported by the supporting legs B, the lower surface of each sheet A is supported by the lower support frame plate 5, and the side part of the sheet A is supported by the side support frame plate 7,
6, the sheets A are assembled in parallel to each other.

In addition, if one of the sheets A is damaged, by sliding the side support frame plates 6, 7 and the lower support frame plate 5 with respect to the pipes 4, 4,
By removing the bent portions 6a, 7a from the recesses 3, 3, the sheet A can be removed, and can be replaced by assembling a new sheet A in the same manner as described above. Since the frame plate 5 is a rectangular flat plate with a flat surface and a length that is the full width of the seat A, it can be supported extremely stably compared to the case where the round pipe 4 is used to support the seat surface and back surface. At the same time, since the end surface of the lower support frame plate is in full contact with the side surfaces of the side support frame plates 6 and 7, both of the side support frame plates 6 and 7 are stably held.

In this way, the present invention forms recesses on both sides of the seat and back of each seat, which are integrally molded so that the seat and back are continuous, and form recesses on the lower side of the seat and the lower side of the back of each seat. Both the front and rear pipes are installed so that they can be supported by support legs, and both pipes are equipped with lower support frame plates that can come into contact with the bottom surface of each seat and side support frames that can engage with the recesses of the seats. Since the plates are slidably fitted into each other, each side support frame plate that fits into both pipes is engaged with the recessed part of the seat, and the bottom of the seat is provided with a flat rectangular shape as described above. As a result of bringing the lower supporting frame plate into contact with the lower supporting frame plate, it is possible to achieve the most desired seat stability in this type of chair.Furthermore, by placing each seat side by side and bringing the supporting frame plate into contact with each other, each seat can be placed sideways. The benches can be easily assembled side by side, and even if one of the seats is damaged, it can be easily replaced by simply sliding the side support frame plate and the lower support frame plate onto the pipe.
The seat can be supported by each frame plate to have a robust structure, and can have a compact structure as a whole, and has features that are easy to manufacture and can be suitably implemented.
