Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a folding chair, and provides a folding chair that is extremely convenient to carry when sketching or doing various other creative activities outdoors.

An embodiment of the present invention will be described below with reference to the drawings. 1
is a short hexagonal column, as shown in Figure 5.
Eight upper connecting pieces 2 are fixed to the upper outer periphery at different positions by 120 degrees and protruding in the radial direction, and eight lower connecting pieces 6 are also attached to the lower outer periphery in the axial direction with respect to the upper connecting pieces 2. They are shifted in position by 60 degrees in the circumferential direction so as not to overlap and are fixed in a state in which they protrude in the radial direction. It is preferable that the column 1 is integrally molded from a lightweight metal material such as an aluminum alloy, but as shown in FIG. 5, the upper connecting piece 2 and the lower connecting piece 6 are provided in different positions and protrude radially. Therefore, if it is difficult to integrally mold the upper half 1a and the lower half 1b, as shown in FIG. It is also possible to have a structure in which the two are integrated by inserting the two.

4 is the upper supporting leg, and 5 is the lower supporting leg, both of which are made by bending a metal plate into a U-shaped cross section.

It is bent so as to close the U-shaped opening on all sides except for a portion of the side connected to the column 1. The upper support leg 4 is
The lower end portion is pivotally and rotatably connected to the upper connecting piece 2 via a pin 6, and the upper end portion is processed to be flat and bent outward to form the support portion 7 of the seat 10. 'still,
The lower support leg 5 has an upper end pivotally connected to the lower connecting piece 3 via a pin 8 so as to be rotatable, and the lower end is processed to be flat and bent outward to form a grounding part 9 7. As best shown in FIG. 5, a step 2a is provided on the upper side of the earth connecting piece 2 as a closing stop, and the upper support leg 4 is attached to the column as shown in FIG. about 80 to the axis of
The stepped portion 2a rotates in the closing direction from the tilted fixed position.
In addition, the outer 1111 edge of the lower connecting piece 6 is formed into an inclined surface 6a that is approximately 30 degrees with respect to the axis of the column 1, and the inclined surface 3a is blocked by the lower supporting leg 5.
When the lower support leg 5 is rotated in the opening direction (i#) and opened to the normal position, the upper end of the lower support leg 5 comes into contact with the inclined surface 3a and acts as an opening stop means to prevent further rotation in the opening direction. It has become.

The seat 10 is made of a strong cloth such as canvas and has a triangular shape with each corner cut into a semicircular shape, and a bag-like body 11 is sewn to the back side of each corner, and the upper support leg 4 A latching portion is formed into which the support portion 7 is inserted and latched. The seat 10 may be made of cloth, leather, synthetic resin, or the like.

The folding chair according to the present invention having the above structure is assembled and used as shown in FIGS. 1 to 6.

That is, when the lower support leg 5 is opened to a fixed position and fixed, it rotates from the upper part to the upper part, and the supporting part 7 is inserted and latched into the seat seat 100 and the bag-shaped body 11, and the seat seat is fixed. 10
It is supported in a stretched state.

When storing or carrying, as shown in FIG. At the closed position of 5, the partial support leg 4 and the lower support leg 5 are bundled. The seat sheet 10 is wrapped around the upper support leg 4 and the lower support leg 5 that are bundled in this way, and the seat sheet 10 is stored or carried around.

Since the folding chair of the present invention has the above-mentioned configuration,
It can be folded into a very compact size, making it very convenient to store and carry. Particularly, as shown in the embodiment, when the supporting legs 4 and 5 are manufactured by bending a metal plate into a U-shaped cross section, the entire structure is extremely lightweight and strong.

Claims (1)

[Claims] 1. A short-axis-shaped column, and at least eight "two-part connecting pieces" fixed to the upper outer periphery of the column at approximately equal intervals and protruding in the radial direction. , at least eight lower connecting pieces fixed to the lower outer periphery of the pillar in a state of protruding in the radial direction at approximately 11 L intervals so as not to overlap with the upper connecting piece in the axial direction; at least eight two-part supporting legs having one end rotatably pivoted on the upper connecting piece and the other end having a support portion for supporting a seat; and one end rotatably pivoting on the lower connecting piece. comprising at least eight lower support legs that are supported and have a grounding part at the other end, and a cloth-like seat sheet that has a hook part on its peripheral edge that prevents the support part of the upper support leg from being detachable; The column has
A closing stop that prevents the upper supporting leg from rotating in the closing direction at a fixed position, and an opening stopper that prevents the -F support leg from rotating in the opening direction at the fixed position, and the seat seat The folding chair is characterized in that the two-part support leg detached from the base can be reversed to the lower support leg side and bundled together with the lower support leg at the closed position of the lower support leg. 2. The folding chair according to claim 1, wherein the upper support leg and the lower support leg are formed by bending a metal plate into a horizontal #1 side U-shape.
