Description

Detailed Description of the Invention

  The present invention relates to a folding portable chair that is mainly used for emergency disasters such as earthquakes, outdoor activities such as camping, and field work in factories.

  A conventional portable chair is known in which a seat is attached to a leg formed by bending a pipe so that the seat can be folded.

Problems to be solved by the invention

  In the conventional portable chair, the flatness is insufficient in the folded state, so when storing a large number of portable chairs, it must be stood side by side, and it is difficult for individuals to carry around was there.

  The present invention provides a portable chair that can be folded and stacked when storing a large number of items, and that can be easily stored in a bag or the like and can be easily carried in light of such problems of the prior art. It is an object.

Means for solving the problem

  In order to achieve the above object, the portable chair of the present invention comprises a substantially box-shaped pedestal, a pair of angled inner struts, a pair of outer struts, an inner strut support and an outer strut support, and the pedestal faces two sides facing each other. Pedestal slits on both sides of the inner struts, inner strut passages on both ends of one side, the inner struts have inner strut slits, and the upper ends of the inner struts and outer struts and the pedestal slits and pedestals The end is movably attached, the inner support and the outer support are fixed to the lower ends of the inner support and the outer support, and the inner support slit part and the central part of the outer support are attached movably.

  In addition, as a member constituting the portable chair, a metal steel plate bent into a box shape or an angle shape, or formed into a shape is used.

  Then, a seat seat that improves the comfort of sitting on the surface of the pedestal can be attached. In this case, it is preferable that a spacer corresponding to the thickness of the seat is attached to the inner support so that it can be stacked.

  In use, the portable chair configured as described above works so that the load is fixed and stable against the reaction force of all attachment points including the slit portion.

  When the pedestal or support is slid along the slit part, the inner support crosses the inner support passage part of the pedestal so that the portable chair becomes flat and can be stacked and folded into a box shape that is easy to carry. To do.

Embodiments of the present invention will be described based on examples with reference to the drawings.
1 to 3, the portable chair is composed of a substantially box-shaped pedestal 1, a pair of angled inner struts 2, a pair of outer struts 3, an inner strut receiver 4 and an outer strut receiver 5, and uses an iron plate or a stainless steel plate. These are formed by sheet metal processing or molding processing. The pedestal 1 has a pedestal slit portion 6 on two opposite sides of the pedestal 1, inner strut passing portions 8 at both ends of one of the two sides, and the inner strut 2 has an inner strut slit portion 7. The pedestal slit portion 6 is a portion where the inner support column 2 slides, the inner support column slit portion 7 is a portion where the outer support column 3 slides, and the inner support column passing portion 8 is a location where the inner support column 2 crosses the pedestal 1.

  And about an above described structure, the upper end part of the inner support | pillar 2 and the outer support | pillar 3, the pedestal slit part 6, and the end part of the pedestal 1 are movably attached using the rivet 11 together with the flat washer 13, and The column support 5 is fixed to the lower ends of the inner column 2 and the outer column 3 by welding, and the inner column slit portion 7 and the central portion of the outer column 3 are movably attached together with a flat washer 13 using a rivet 12.

  In the embodiment shown in FIG. 4, a rectangular seat 9 is fixed to the base 1 in FIGS. 1 to 3 with screws 14. In the embodiment, it is rectangular, but it may be circular, elliptical or the like. Further, for the purpose of horizontally stacking the folded portable chairs, a resin spacer 10 having the same thickness as that of the seat seat 9 is attached to the inner support 4.

  FIG. 5 shows a folding process of the portable chair.

  FIG. 6 shows a state where the portable chair of FIG. 3 is folded and stacked.

  FIG. 7 shows a state in which the portable chair attached with the seat of FIG. 4 is folded and stacked.

The invention's effect

  Since the present invention is configured as described above, the following effects can be obtained.

  In the portable chair according to claim 1, since the slit portion and the inner column passage portion are provided, it is possible to stack a bundled quantity by sliding the pedestal or the column, and it is folded into a box shape that is convenient for carrying. Can do. Furthermore, it can be used as an instant storage table if a plurality of pieces are placed side by side, and it can be easily manufactured by processing a metal plate into sheet metal or forming, and it is lightweight and externally visible. Even simple and excellent stability.

  Since the portable chair according to the second aspect is provided with a seat, the seating comfort can be improved.

  It is a front external view of a portable chair.   It is a side external view of a portable chair.   It is a figure which shows the state folded.   It is a bottom view which shows the state which attached the seat sheet and folded.   It is a figure which shows a folding process.   It is the figure folded and stacked.   It is the figure which attached the seat sheet | seat and folded and stacked | stacked.
