Description

  The present invention relates to a folding portable chair that can be used outdoors such as camping and fishing. More specifically, the seat can be folded separately as well as the legs, and the transport box can be folded with the legs and seat folded. It is intended to provide a novel folding portable chair that can be transported at the same time.

  Conventional folding chairs are known as folding chairs that can be folded by attaching a seat portion to the tip of the X-shaped leg, but the seat portion of a small area because the width of the seat portion is limited by the X legs. I had to install it.

  As a chair for solving these problems, Japanese Utility Model Laid-Open No. 7-16646 “Kisekae Chair” discloses a “chair capable of detachably attaching a seat integrated with a back and a seat to a frame portion”. As described above, it is known to use a seat in which an openable / closable X-shaped leg, a back and a seat are integrated.

Utility Model No. 2505338 “Folding Chair” includes “a cloth constituting a seating portion and a backrest portion, one rear support base, two front support tools arranged on the left and right sides, and a seating portion of the cloth. Two connection support tools whose both ends are fixed, two support columns that are erected in parallel to the rear support leg at a predetermined interval and support the upper end of the backrest portion of the cloth at the upper end portion, It is arranged so as to straddle between the struts in the middle part of the struts, and includes a slide plate that is slidably supported by the two struts, and a slide plate that is slidably supported by the two struts, A slide chair and two front support tables, a rear support table and two connection supports, a connection support device, and a front support table on the opposite side are connected to each other via a bar-like leg.

  The above conventional folding chair can be folded by opening and closing the X-shaped rod-shaped leg fixed to the leg portion with a support base. I couldn't halve it.

  For this reason, it is possible to fold and fold the sheet part with the same width as that of the leg part, but in this case, the sheet part cannot be widened and is not sufficient as a sheet width in use. Therefore, there has been a demand for the development of a portable folding chair that has both a seat portion and a backrest portion, and a seat portion and a leg portion that can be folded compactly when not in use.

  The present inventor has intensively studied to solve such a problem. As a result, the seat and the backrest are sewn in a semicircular shape to facilitate folding, and an annular stitch is formed at the end of these sewing sheets. We have found that it is possible to secure a sufficient seating part and backrest part by manufacturing a folding seat part through which a foldable torus is inserted by providing a seating hole, and attaching this seat part with the leg part opened. The portable folding chair of the present invention could be provided.

  That is, the first of the present invention is an X-shaped foldable limb leg, a fixed base for fixing the limb leg tip, and a support leg extending from the fixed base, and the support A folding chair comprising a rod tip and a seat portion that can be locked to the folding leg leg tip, wherein the seat portion is a torus that passes through a sewing hole in a seat portion and a seat edge, And a ring member of the seat portion is fitted into the groove portion of the support rod tip, and the folding leg leg tip portion is inserted into the small hole of the catch portion. It is a portable chair for folding characterized by fixing a part.

  A second aspect of the present invention is the support in which the leg portion is extended from the rear fixing base when the leg portion is fixed to be opened and closed by a plurality of fixing bases that fix the distal end portions of the X-shaped foldable limb legs. The folding portable chair according to claim 1, wherein a plurality of upper fixing portions through which the rods are inserted are configured to be movable up and down along the support rods.

  A third aspect of the present invention is the folding portable chair according to claim 1 or 2, wherein a fixing portion provided with a U-shaped groove is attached to a support rod tip of the leg portion. .

  A fourth aspect of the present invention is that the torus of the seat portion is composed of a plurality of toruses and a fixture for fixing the tip of the torus, and the tip of the torus is freely forward and backward. The folding portable chair according to claim 1, wherein the annular body and the seat part are foldable by being fixed to the body.

  The folding portable chair of the present invention can be easily transported because the leg portion and the seat portion can be separately compactly folded and placed in the transport box.

  The seat and backrests are sewn in a semi-spherical shape to facilitate folding, and a folding seat portion is provided with an annular sewing hole at the end of these sewing seats and a foldable torus inserted therethrough. This makes it possible to sit comfortably during use, making it a chair that can withstand long-term use.

  Hereinafter, the present invention will be described in detail with reference to the drawings, but the scope of the present invention is not limited thereto.
