[0003]

[BRIEF DESCRIPTION OF THE INVENTION] Such a bench also
Since it is possible to sit down with a seat on the seat and a back on the back, there is no particular problem as a chair to be used when waiting for a train or the like or a chair to be used temporarily.
However, there are various problems or drawbacks as a leisure bench used on the beach, veranda, garden, etc. or a bench for 2-3 people for rest. For example, the sitting height varies depending on the height, but the conventional bench has a fixed height, so tall people must sit down in a cramped fashion,
In addition, the low person sits down with his feet floating from the ground, and is not suitable for a resting bench. Further, when the seat for sitting down is at an appropriate height and the back for carrying the back is at a predetermined angle with respect to the seat, it is possible to sit down with the posture corrected. On the other hand, when the seat portion is lowered and the person sits comfortably, it is desirable that the back portion has a small angle as if lying down. However, in the conventional bench, the height of the seat portion and the angle of the back portion with respect to the seat portion are fixed, so that the above requirements cannot be satisfied. Furthermore, since the legs, the seat, the back and the like are integrally formed, there is a drawback that the legs are heavy and cannot be carried to a campsite or the like. Therefore, in the present invention, the height of the seat portion is adjustable, and the angle of the back portion for carrying the back is changed,
Furthermore, it aims at providing the multistage bench which can be easily disassembled.

[Operation] A stool is attached to the pair of leg frames.
That is, a bench is assembled by tightening, for example, bolts and wing nuts, on the horizontal support members of the pair of leg frames, a seat portion for seating on the seat portion, and a back portion on which the upper portion of the first leg member is seated. In reverse order, disassemble into a pair of leg frames and a stool and carry. When assembled and installed, the bench bears a load, so that the stopper is locked to the upper edge of the through hole. Therefore, the first leg member 1 and the horizontal support member, and the horizontal support member and the second leg member are fixed to each other while being pivotally attached to each other. That is, sit at that height.
To adjust the height, the stopper is disengaged from the upper edge of the through hole. Then, if the crossing angle between the second leg member and the first leg member is changed so that, for example, the stopper located at the top is locked at the upper edge of the through hole, the seat portion of the stool portion becomes the lowest. . On the contrary, when the stopper located at the lowermost position is engaged with the upper edge of the through hole, the height becomes highest. Adjusting the height of the seat of the stool changes the angle of the first leg member,
The angle of the back to the back with respect to the seat also changes automatically.

31, ... These plate materials 31, 3
1, ... Are selected to have a length that allows two or three people to sit on them, and are connected by cloth bands or strings 32, 32 at a predetermined interval. Therefore, the stool K has a child-like shape. Plate materials 31, 31 formed in the shape of a cage
At both ends of the plate members 31, 31 corresponding to the through holes 5 and 5 of the first leg member 1 and the through hole 24 of the horizontal support member 20 at the time of assembly, holes 3 for inserting bolts are provided.
3, 33, ... Are formed. These holes 33, 3
The diameters of 3, ... Have two steps, and when the bolt is passed through, the head of the bolt does not appear on the surface of the plate members 31, 31 ,.

Next, the operation of the above embodiment will be described.
The leg frame F, as shown in FIGS. 1 and 3, is assembled as follows. In the shaft holes 7, 7 of the first leg member 1,
The shaft holes formed at the rear end of the horizontal support member 20 are aligned. Then, through the bolt shaft 9, use a wing nut to prevent the bolt shaft 9 from falling off. Thereby, the first leg member 1 and the horizontal support member 20 are pivotally attached to each other. First
The second leg member 10 is passed through the square through hole 8 formed in the leg member 1 so that the stoppers 14, 14, ... Are on the upper side, and the shaft hole formed at the tip end thereof is horizontally supported. Aligned with the shaft holes 22, 22 of the member 20, and the bolt shaft 2
Pass through 6 and tighten with wing nut. As a result, the second leg member 10 and the horizontal support member 20 are pivotally attached to each other, and the assembly of the one leg frame F is completed.

The other leg frame F is similarly assembled. The stool K is attached to the pair of leg frames F, F. That is, the pair of leg frames F, the through holes 5, 5, 2 of the F
4 are aligned with the holes 33, 33, ... Of the stool portion K, and the bolts 35, 35, 35 are passed from the front surface side of the plate members 31, 31 ,. Then, tighten the wing nuts 36, 36, ... to finish the bench assembly. The assembled state and the installed state are shown in FIG. Obviously, it can be disassembled into all the elements by the reverse procedure, but it can also be disassembled into the pair of leg frames F, F and the stool K and carried.

When assembled and installed as described above, since the bench is loaded, the stopper 14 is locked to the upper edge of the rectangular through hole 8 as shown in FIG. Therefore, the first leg member 1 and the horizontal support member 20, and the horizontal support member 20 and the second leg member 10 are
They are each pivotally connected to each other at 26, but are fixed.
That is, it is possible to sit down at that height. When the horizontal support member 20 is lifted or the ground contact portion 13 of the second leg member 10 is lowered to adjust the height, the stopper 14 is disengaged from the upper edge of the rectangular through hole 8. Therefore, the intersecting angle between the intermediate portion 12 of the second leg member 10 and the intermediate portion 4 of the first leg member 1 is changed so that, for example, the stopper 14 located at the top is locked to the upper edge of the rectangular through hole 8. By doing so, the seat portion 37 of the seating portion K becomes the lowest. On the contrary, when the stopper 14 located at the lowermost position is locked to the upper edge of the rectangular through hole 8, the height becomes the highest.

Even if the height is adjusted in this manner, the horizontal support member 20 is kept substantially horizontal because the intermediate portions 4 and 12 of the first and second leg members 1 and 10 intersect each other. Therefore, the stool K attached to the horizontal support member 20
The seat portion 37 of is also kept substantially horizontal. Also, the seat 3 of the stool K
When the height of 7 is adjusted, the angle of the first leg member 1 changes, so that the angle of the upper portion 2, that is, the back portion 38 for backing.
The angle with respect to the seat portion 37 also changes automatically. More specifically, if the seat portion 37 of the stool K is raised,
The angle of the back portion 38 with respect to the seat portion 37 is close to 90 degrees, and it is possible to sit down with a relatively correct posture. On the other hand, the lower the angle, the larger the angle, so that you can sit down like an easy chair.
