- FIGS. 1 and 2 are perspective views showing a first embodiment of the present invention. In each case, the leg members 1 and 1 are shown in an X-shaped open state.
- Figure 1 shows leg members 1 and 1 consisting of two pipes that are bent and formed in the same plane and open in an X-shape.
- the leg members 1 and 1 are attached to the connecting rod 3 with shaft bolts 2 and 2 so as to open and close in an X-shape on the same axis at the front and rear places.
- the cantilevered seating support frame 4, 4 which has a curved line that is slightly inclined toward the rear, Has formed.
- the upper rear portion is turned rearward for stepping, and then bent back to form rotating connecting portions 6, 6 for rotatably supporting the backrest supporting frames 5, 5.
- the backrest supporting frames 5, 5 have a configuration in which the lower portion is inserted, and the upper ends of the pivotally connecting portions 6, 6, which are rotatably and detachably mounted, are directed upward so as to form a backrest. ing.
- the fishing fulcrums 7, 7 provided at the free end of the cantilever support frames 4, 4 and the fishing fulcrums 8, 8, which are provided slightly below the backrest support frames 5, 5, can be easily attached and detached via the jungle members 9, 9. I support it.
- the fishing fulcrum 7, 7 may be arbitrarily provided at a position where the tilt angle of the backrest is appropriately set.However, if the fulcrum 7 is provided at a position aligned with the axis of the rotation connecting portions 6, 6, the backrest supporting frame 5, The distance between the fishing fulcrums 7, 7 and the fishing fulcrums 8, 8 is constant and does not change, regardless of the direction in which the fulcrum 5 rotates and tilts in any direction. On the other hand, it can be seen from the drawing that the distance between the left and right sides of the backrest support frames 5, 5 becomes narrowest in the vertical state, and becomes wider as the front or rear direction is inclined.
- FIG. 2 shows a state in which the seat sheet 10 and the back sheet 11 are used with the frame of FIG.
- the front end of the seat sheet 10 has a cylindrical shape that covers the position of the shaft bolt 2 that opens and closes in the X shape at the front of the leg member, and is attached so that it can be fitted from the free end of the cantilever. I have.
- the rear seat 11 is fitted from the upper free end into the backrest support frame attached through the holes 12 and 12 provided in the seat seat 10.
- the front edge of the seat sheet forms an effective rim by providing the left and right front end portions of the seat support frame with protrusions that are bent round toward the front.
- the seat sheet keeps a curved surface according to the intention of setting, and the rear seat becomes tensed and stabilizes with front and rear cushioning.
- the fishing member is easily attached to and detached from the fishing fulcrum with a string, and the outer surface is covered with an effective cover body 13 as an elbow rest.
- FIG. 3 is a perspective view showing a second embodiment of the present invention.
- the seat and back sheet are taken off, and leg members 1 and 1 are shown in an open state in an X shape.
- the cantilever free ends of the seat support frames 4, 4 with pipes with horizontal front and rear A cylindrical pipe piece is fixed at a position aligned with the axis of the connecting portions 6 and 6 to form support holes 14 and 14, and a protruding piece is provided at the rear to stably support the rear end of the seat sheet 10. Is being measured.
- a ring piece that plays a role of a stopper that is pressed down on the upper surface of the support hole provided in the seat support frame so that the seat surface and the back surface move in unison I have.
- the holes in the support holes have a reasonable margin.
- a state in which a coil spring is further added between the support hole and the rotation connection portion may be considered.
- the mutual separation between the cantilever free end of the seat supporting frame and the rotary connection portions 6 and 6 results in the free attachment and detachment of the seat seat and an appropriate cushioning effect when sitting.
- the pressure smoothly and integrally transitions from the seat to the back, or from the back to the seat.
- FIG. 4 is a perspective view showing a third embodiment of the present invention. It is a small one with lower backrest support frames 5, 5 to support the lower back. A part of the seat is cut away for easy understanding of the structure of the frame with the seat sheet 10 and the back sheet 11 attached.
- the support hole 14 is formed by press-molding a pipe, and the rest is the same as the embodiment of FIG.
- leg members can be considered in various ways. Although one pipe is formed by bending only, it is conceivable that the front part and the rear part are connected separately as separate members. Since the fishing member can be of a fixed length, it can be soft or hard as long as it can move freely at the fulcrum, and it is possible to use various materials. Industrial applicability
- the back seat becomes tensed to the left and right in response to the pressure of a person leaning on the seat, and together with the cantilever seat, a flexible front-back inclination and cushioning are involved.
- the backrest support frame is mounted so that it can be folded and rotated about an axis parallel to the X-shaped opening and closing direction of the leg members, so that the degree of freedom in the left, right, up and down directions in the open state is increased. It can be a tall, rich type of backrest.
- the mounting and dismounting of the legs is very easy, so various combinations of seat and back shapes are easy. It is also convenient for changing sheets and washing.
- the seat support frame has a cantilevered free end with a particular cushioning property, it is relatively small when integrally connected to and supported by the back support frame through a support member or through a support hole.
- a frame made of a simple member can cope with the support load of the seat. If the fishing member is provided so that the position of the jun supporting point on the seating support frame is aligned with the axis of the rotation connection part, the backrest support frame rotates and the seat can be tilted in any direction. The distance between the back fulcrums is constant and does not change. Therefore, the load applied to the seat is applied to the lower part of the leg and continuously and stably transmitted to the backrest supporting frame, and is concentrated on the lateral tension of the rear seat.
- the present invention is not only a basic system for constructing a chair, but also produces a chair of a new size, which has never existed before. Because it is presumed to be foldable, it can be used as a living style furniture based on so-called floor seats, which can be used immediately and put away to create a large space. It is convenient for organizing and storing, carrying and transporting. Although it has a very simple structure and advanced functions, it is also suitable for various forms, especially for developing the shape of the backrest while sharing the shape of the seat.
