Description

本発明は椅子に関する。   The present invention relates to a chair.

椅子は人が座る際に使う道具（家具）である。腰掛けとも謂われる。椅子は、天然木、合板、パーティクルボード、竹、籐、ステンレス鋼、アルミニウム、天然石、陶磁器などで作製されている。   A chair is a tool (furniture) used when a person sits down. Also called a stool. The chair is made of natural wood, plywood, particle board, bamboo, rattan, stainless steel, aluminum, natural stone, ceramics and the like.

ところで、平常時には，快適な長椅子として使用でき、緊急時には、２台の担架として使用できる機能を備えた担架兼用長椅子が提案（特許第４９２３３０７号）されている。すなわち、地震・火災・人命救助等の緊急使用時に担架として使用できる背もたれ部、及び、地震・火災・人命救助等の緊急使用時に担架として使用できる座面部とを長椅子本体に対して着脱可能とした担架兼用長椅子が提案されている。前記担架兼用長椅子が説明される。図５において、２１は担架兼用長椅子である。２２，２３は袖部である。２４は背もたれ部、２５は座面部である。背もたれ部２４及び座面部２５は、同一形状に形成され、担架兼用長椅子２１から分解した場合に、担架として機能する。背もたれ部２４及び座面部２５を２台の担架として機能させる為、背もたれ部２４の両端及び座面部２５の両端には、一対の担架握り手部が設けられている。   By the way, a stretcher combined chaise longue having a function that can be used as a comfortable chaise lounge during normal times and can be used as two stretchers in an emergency has been proposed (Japanese Patent No. 4923307). In other words, the backrest that can be used as a stretcher during emergency use such as earthquake, fire, and lifesaving and the seat that can be used as a stretcher during emergency use such as earthquake, fire, and lifesaving can be attached to and detached from the chaise longue body. A stretcher lounge has been proposed. The stretcher combined lounge is described. In FIG. 5, 21 is a stretcher combined chair. Reference numerals 22 and 23 denote sleeve portions. Reference numeral 24 denotes a backrest portion, and 25 denotes a seat surface portion. The backrest part 24 and the seat surface part 25 are formed in the same shape, and function as a stretcher when disassembled from the stretcher combined chair 21. In order for the backrest portion 24 and the seat surface portion 25 to function as two stretchers, a pair of stretcher grip portions are provided at both ends of the backrest portion 24 and both ends of the seat surface portion 25.

特許第４９２３３０７号Patent No. 4923307

さて、前記特許文献１の担架兼用長椅子は、地震・火災・人命救助等の緊急使用時に、担架として使用できる。   Now, the stretcher lounge of Patent Document 1 can be used as a stretcher during emergency use such as earthquake, fire, and lifesaving.

しかし、前記担架兼用長椅子一脚から提供される担架は２台に過ぎない。地震などの防災時に必要な担架は非常に多い。一台や二台では済まない。多数の担架が必要ならば、それに応じて、前記担架兼用長椅子を、Ｎ脚、用意しておけば済むかも知れない。とは言うものの、前記担架兼用長椅子は場所を取る。前記担架兼用長椅子を、一定の場所に、数多く、設置すると言うのは、非現実的である。   However, there are only two stretchers provided from the stretcher combined chair. There are a lot of stretchers necessary for disaster prevention such as earthquakes. One or two is not enough. If a large number of stretchers are required, it may be sufficient to prepare N legs as the stretcher and chaise longue accordingly. That said, the stretcher lounge takes up space. It is unrealistic to install a large number of stretcher lounge chairs in a certain place.

従って、本発明が解決しようとする課題は、複数の担架を簡単に用意できる椅子を提供することである。   Therefore, the problem to be solved by the present invention is to provide a chair capable of easily preparing a plurality of stretchers.

前記第１軸Ａｋと前記第２軸Ｂｋとの間に架け渡されたシートＣｋは、前記第１軸Ａｋおよび前記第２軸Ｂｋが前記椅子に装着されている時（組立時）には、好ましくは、前記第１軸Ａｋおよび／または前記第２軸Ｂｋに巻かれている。本発明では、シートが用いられたことから、前記シートは前記第１軸Ａｋおよび／または前記第２軸Ｂｋへの巻回が可能になった。これによって、前記第１軸Ａｋおよび前記第２軸Ｂｋの数を多く出来る。すなわち、一脚の椅子から数多くの担架が得られる。前記シートＣｋは、好ましくは、記第１軸Ａｋおよび前記第２軸Ｂｋが前記椅子から取り外されている時（分解時）には、好ましくは、巻き解かれる。これによって、担架となる。担架使用時において、人はシート上に乗せられる。硬い板上に乗せられるのでは無いから、運ばれる患者の感触は良い。 The sheet C k which passed laid between the first axis A k and the second axis B k, when the first axis A k and the second axis B k are attached to the chair (Assembly the time), preferably, are wound around the first axis a k and / or the second axis B k. In the present invention, since the sheet is used, the sheet can be wound around the first axis Ak and / or the second axis Bk . Accordingly, the number of the first axis A k and the second axis B k can be increased. That is, many stretchers can be obtained from a single chair. The seat C k is preferably unrolled when the first axis A k and the second axis B k are removed from the chair (when disassembled). This becomes a stretcher. When using a stretcher, a person is placed on the seat. Since it is not placed on a hard board, the patient feels good.

好ましくは、前記第１軸および前記第２軸の端部には螺子溝が設けられてなり、前記左側枠部には前記第１軸および前記第２軸の左端部が挿入される孔が形成されてなり、前記右側枠部には前記第１軸および前記第２軸の右端部が挿入される孔が形成されてなり、前記孔に前記第１軸および前記第２軸の端部が、各々、挿入され、前記挿入された前記第１軸および前記第２軸の螺子溝に螺子が螺着され、前記第１軸および前記第２軸が前記左側枠部および前記右側枠部に取り付けられてなる。これにより、椅子への組立、及び椅子からの分解が、極めて、簡単になる。   Preferably, screw grooves are provided at end portions of the first shaft and the second shaft, and a hole into which the left end portions of the first shaft and the second shaft are inserted is formed in the left frame portion. A hole into which the right end portion of the first shaft and the second shaft is inserted is formed in the right frame portion, and the end portions of the first shaft and the second shaft are formed in the hole, Each is inserted, and screws are screwed into screw grooves of the inserted first shaft and second shaft, and the first shaft and the second shaft are attached to the left frame portion and the right frame portion. It becomes. This greatly simplifies assembly and disassembly from the chair.

前記第１軸および前記第２軸は、好ましくは、パイプである。これにより、軽量化が図れる。   The first shaft and the second shaft are preferably pipes. Thereby, weight reduction can be achieved.

以下、より具体的な実施形態が挙げられる。但し、本発明は以下の実施形態のみに限定されない。本発明の特長が大きく損なわれない限り、各種の変形例や応用例も本発明に含まれる。   Hereinafter, more specific embodiments will be mentioned. However, the present invention is not limited only to the following embodiments. Various modifications and application examples are also included in the present invention as long as the features of the present invention are not greatly impaired.

図１〜図４は本発明の一実施形態になる椅子の説明図である。図１は椅子の斜視図、図２は椅子のＸ−Ｘ線断面図、図３はＹ−Ｙ線断面図、図４は椅子が分解されて提供される担架の斜視図である。   1-4 is explanatory drawing of the chair which becomes one Embodiment of this invention. 1 is a perspective view of the chair, FIG. 2 is a sectional view taken along line XX of the chair, FIG. 3 is a sectional view taken along line YY, and FIG. 4 is a perspective view of a stretcher provided with the chair disassembled.

１は右側板である。２は左側板である。長椅子の側板であることを考慮すると、側板１，２の厚さ（幅）は、例えば１０ｃｍ程度は有る。右側板１や左側板２は、各々、２枚の板が組み合わされた中空構造体であっても良い。右側板１や左側板２は、厚さ（幅）が１０ｃｍ程度も有ることから、右側板１や左側板２は肘掛用の袖部としての機能を奏する。その他、椅子としての一般的な構造を具備する。右側板１の所定位置には、孔が、形成されている。左側板２の所定位置には、孔が、形成されている。右側板１と左側板２とを合わせた場合、右側板１の孔と左側板２の孔とは合致する。前記孔の数は、後述の軸３，４の数と同じである。勿論、前記孔の数の方が多くても良い。   Reference numeral 1 denotes a right side plate. 2 is a left side plate. Considering that it is a side plate of a chaise longue, the thickness (width) of the side plates 1 and 2 is, for example, about 10 cm. Each of the right side plate 1 and the left side plate 2 may be a hollow structure in which two plates are combined. Since the right side plate 1 and the left side plate 2 have a thickness (width) of about 10 cm, the right side plate 1 and the left side plate 2 function as armrest sleeves. In addition, it has a general structure as a chair. A hole is formed at a predetermined position of the right side plate 1. A hole is formed at a predetermined position of the left side plate 2. When the right side plate 1 and the left side plate 2 are combined, the hole in the right side plate 1 matches the hole in the left side plate 2. The number of the holes is the same as the number of shafts 3 and 4 described later. Of course, the number of the holes may be larger.

３は第１軸である。４は第２軸である。前記軸３，４は、本実施形態では、中空状のパイプである。長さは、例えば２ｍ程度である。勿論、これに限られないが、人の身長よりは長い。第１軸（パイプ）３及び第２軸（パイプ）４は、軽金属あるいは樹脂などの軽量素材で出来ている。勿論、パイプであるから、軽量である。前記パイプの形状は、断面円形である。尚、断面四角形であっても良い。但し、断面が非円形の場合でも、端部は円形である。前記軸（パイプ）３，４の数は、各々、例えば１０本である。勿論、これに限られない。２０本であっても良い。３０本であっても良い。前記軸３，４の端部の外周面には螺子溝（図示せず）が形成されている。   Reference numeral 3 denotes a first axis. Reference numeral 4 denotes a second axis. The shafts 3 and 4 are hollow pipes in the present embodiment. The length is about 2 m, for example. Of course, but not limited to this, it is longer than the height of the person. The first shaft (pipe) 3 and the second shaft (pipe) 4 are made of a lightweight material such as a light metal or a resin. Of course, since it is a pipe, it is lightweight. The pipe has a circular cross section. The cross section may be a quadrangle. However, even when the cross section is non-circular, the end is circular. The number of the shafts (pipes) 3 and 4 is 10 for example. Of course, it is not limited to this. 20 may be sufficient. 30 may be sufficient. A screw groove (not shown) is formed on the outer peripheral surface of the end portion of the shafts 3 and 4.

５は、第１軸３の端部（左端部および右端部）近傍の位置に形成された鍔である。６は、第２軸４の端部（左端部および右端部）近傍の位置に形成された鍔である。鍔５，６の外径は、前記板１，２に形成されている孔の内径より、大きい。   5 is a ridge formed at a position in the vicinity of the end portions (left end portion and right end portion) of the first shaft 3. 6 is a gutter formed at a position in the vicinity of the end portions (left end portion and right end portion) of the second shaft 4. The outer diameters of the flanges 5 and 6 are larger than the inner diameters of the holes formed in the plates 1 and 2.

７はシートである。シート７は、例えば綿などの布製である。シート７の数は前記軸３（４）の数に等しい。シート７の幅は、シート７上に人を乗せることが可能な幅である。例えば、７０〜８０ｃｍである。シート７の一端側は第１軸３に取り付けられている。シート７の他端側は第２軸４に取り付けられている。従って、第１軸３と第２軸４とは、シート７を介して、繋がっている。シート７は第１軸３に巻かれている。シート７は、特に、第１軸３のみに巻回されている。椅子に座した時、人体は巻回シート７に、直接、触れる。シート巻回厚さが厚い方がクッション性に富む。従って、人体が接触する側に位置する第１軸３のみに、シート７は、巻かれたものとした。勿論、座した時に、人体が触れない個所に設けられている場合には、シート７は、その半分が第１軸３に巻かれており、残り半分が第２軸４に巻かれていても良い。強度上の観点から、第１軸３や第２軸４が設けられている個所にあっては、シート７は何れかにのみ巻回されなければならないと言う必然性は低い。前記巻回状態のシート７が巻き解かれると、第１軸３とシート７と第２軸４とで、一つの担架が、構成される（図４参照）。一つの椅子に、第１軸３及び第２軸４が、各々、２０本有るとすると、一つの椅子が分解されると、合計、２０個の担架が用意できることになる。   Reference numeral 7 denotes a sheet. The sheet 7 is made of a cloth such as cotton. The number of sheets 7 is equal to the number of the shafts 3 (4). The width of the seat 7 is a width that allows a person to be placed on the seat 7. For example, it is 70-80 cm. One end side of the sheet 7 is attached to the first shaft 3. The other end side of the sheet 7 is attached to the second shaft 4. Therefore, the first shaft 3 and the second shaft 4 are connected via the seat 7. The sheet 7 is wound around the first shaft 3. In particular, the sheet 7 is wound only on the first shaft 3. When sitting on a chair, the human body directly touches the wound sheet 7. A thicker sheet winding thickness provides more cushioning. Therefore, the sheet 7 is wound only on the first shaft 3 located on the side in contact with the human body. Of course, if the seat 7 is provided at a place where the human body does not touch when sitting, the half of the seat 7 is wound around the first shaft 3 and the other half is wound around the second shaft 4. good. From the viewpoint of strength, it is not necessarily necessary to say that the sheet 7 must be wound only in one place where the first shaft 3 and the second shaft 4 are provided. When the wound sheet 7 is unwound, the first shaft 3, the sheet 7, and the second shaft 4 constitute one stretcher (see FIG. 4). If there are 20 first shafts 3 and 2 second shafts 4 in one chair, when one chair is disassembled, a total of 20 stretchers can be prepared.

前記シート７が巻回状態の第１軸３及び第２軸４の右端部が、右側板１の孔に挿入される。前記シート７が巻回状態の第１軸３及び第２軸４の左端部が、左側板２の孔に挿入される。右側板１の孔から突出している第１軸３及び第２軸４の右端部の螺子溝には螺子８が螺着される。左側板２の孔から突出している第１軸３及び第２軸４の左端部の螺子溝には螺子９が螺着される。螺子８，９と鍔５，６によって、右側板１及び左側板２は挟持されているので、構造物は堅固である。右側板１及び左側板２に形成されている孔は、椅子の背板や座板に相当する個所に形成されている。従って、第１軸３及び第２軸４が右側板１及び左側板２の孔に挿入された場合、第１軸３及び第２軸４並びにシート７によって、背板や座板の機能が奏されるようになる。すなわち、第１軸３及び第２軸４が右側板１及び左側板２の孔に挿入された場合、これによって、椅子が構成される。   The right end portions of the first shaft 3 and the second shaft 4 where the sheet 7 is wound are inserted into the holes of the right side plate 1. The left end portions of the first shaft 3 and the second shaft 4 where the sheet 7 is wound are inserted into the holes of the left side plate 2. A screw 8 is screwed into the screw groove at the right end of the first shaft 3 and the second shaft 4 protruding from the hole of the right side plate 1. A screw 9 is screwed into the screw groove at the left end portion of the first shaft 3 and the second shaft 4 protruding from the hole of the left side plate 2. Since the right side plate 1 and the left side plate 2 are sandwiched by the screws 8 and 9 and the flanges 5 and 6, the structure is solid. The holes formed in the right side plate 1 and the left side plate 2 are formed at locations corresponding to the back plate and seat plate of the chair. Therefore, when the first shaft 3 and the second shaft 4 are inserted into the holes of the right side plate 1 and the left side plate 2, the functions of the back plate and the seat plate are achieved by the first shaft 3 and the second shaft 4 and the seat 7. Will come to be. That is, when the 1st axis | shaft 3 and the 2nd axis | shaft 4 are inserted in the hole of the right side board 1 and the left side board 2, a chair is comprised by this.

図中、１０は右側板１に形成された適宜な模様の切欠部である。１１は、左側板２に形成された適宜な模様の切欠部である。   In the figure, reference numeral 10 denotes a notch having an appropriate pattern formed on the right side plate 1. Reference numeral 11 denotes a notch having an appropriate pattern formed on the left side plate 2.

上記構造の椅子に座った場合、人体はシート７に接触する。シート７は第１軸３に巻回されているから、適度なクッション性を持つ。従って、座した時の感触は良い。本実施形態の椅子にあっては、座板に相当する面は、シート７が巻回された第１軸３によって構成される。第１軸３の下側（後部側）に配置された第２軸４には、腰（背）が、直接、接することが無い。従って、シート７は第２軸４に巻回されていない。但し、第１軸３の下に第２軸４が設けられている構造によって、椅子としての機械的強度は確保されている。背板に相当する個所にあっても、第１軸３の後部側に第２軸４が配置されている。この個所にあっても、前部側の第１軸３にシート７は巻回されている。   When sitting on a chair having the above structure, the human body contacts the seat 7. Since the seat 7 is wound around the first shaft 3, it has an appropriate cushioning property. Therefore, the feeling when sitting is good. In the chair of the present embodiment, the surface corresponding to the seat plate is configured by the first shaft 3 around which the seat 7 is wound. The waist (back) does not directly contact the second shaft 4 disposed on the lower side (rear side) of the first shaft 3. Therefore, the sheet 7 is not wound around the second shaft 4. However, the mechanical strength as a chair is ensured by the structure in which the second shaft 4 is provided under the first shaft 3. Even in a portion corresponding to the back plate, the second shaft 4 is disposed on the rear side of the first shaft 3. Even in this place, the seat 7 is wound around the first shaft 3 on the front side.

緊急事態が起きて、多数の担架が必要な場合、螺子８，９が取り外される。椅子は、簡単に、分解される。椅子の分解が簡単と言うことは、逆に、組立も簡単と言うことである。椅子が分解されると、図４に示される担架が、数多く、提供される。本実施形態の場合であれば、一つの椅子から１０個の担架が提供される。従って、非常に、有効である。   If an emergency occurs and a number of stretchers are required, the screws 8 and 9 are removed. The chair is easily disassembled. The fact that the chair is easy to disassemble means that it is easy to assemble. When the chair is disassembled, a number of stretchers as shown in FIG. 4 are provided. In the case of this embodiment, ten stretchers are provided from one chair. Therefore, it is very effective.

上記実施形態にあっては、座板部に相当する個所において、第２軸４は第１軸３の下に設けられていた。しかし、第１軸３と第２軸４とは、前記実施形態の如く、上下位置ではなく、同じ高さ位置（前後位置）に設けられていても良い。但し、この場合、座板部における凹凸を少なくする為、シート７は、第１軸３と第２軸４とに等分に巻回される。又、背もたれ部においては、前記実施形態の如く、前後位置ではなく、上下位置に設けられていても良い。但し、この場合も、背もたれ部における凹凸を少なくする為、シート７は、第１軸３と第２軸４とに等分に巻回される。   In the above-described embodiment, the second shaft 4 is provided below the first shaft 3 in a portion corresponding to the seat plate portion. However, the 1st axis | shaft 3 and the 2nd axis | shaft 4 may be provided in the same height position (front-back position) instead of an up-down position like the said embodiment. However, in this case, the sheet 7 is wound equally around the first shaft 3 and the second shaft 4 in order to reduce unevenness in the seat plate portion. Further, the backrest portion may be provided not in the front-rear position but in the vertical position as in the above embodiment. However, also in this case, the sheet 7 is wound equally around the first shaft 3 and the second shaft 4 in order to reduce unevenness in the backrest portion.
