Description

椅子Chair
　本発明は、背と座とを有する椅子であって、座を上方に跳ね上げた状態で前後方向に重ね合わせ（ネスティング）が可能な椅子に関する。 The present invention relates to a chair having a back and a seat, which can be overlapped (nested) in the front-rear direction with the seat flipped upward.
　従来、背と座とを有する椅子であって、座を上方に跳ね上げた状態で前後方向にネスティング可能な椅子が知られている。例えば、特許文献１に記載の椅子は、側面視で門形の前後脚を左右にそれぞれ有し、当該左右の脚間に水平な水平杆を架設してなる脚部であって、後脚をさらに上方へと延設して背を取り付けるとともに、座の後端を回動自在に軸支する構成である。そして、当該座の使用時において、座を水平に回動し、当該座の下面を水平杆で受ける構成である。 Conventionally, a chair having a back and a seat that can be nested in the front-rear direction with the seat flipped upward is known. For example, the chair described in Patent Document 1 is a leg portion having a gate-shaped front and rear legs on the left and right sides in a side view, and a horizontal horizontal ridge constructed between the left and right legs. Further, it is configured to extend upward and attach a back, and to pivotally support the rear end of the seat so as to be rotatable. And when using the said seat, it is the structure which rotates a seat horizontally and receives the lower surface of the said seat with a horizontal rod.
　このような椅子においては、脚部材を門形に成型すべく、脚パイプを略直角方向に大きく曲げる工程を要するため、成型工程が複雑で高コストといった欠点がある。特に、門形の脚部材のため使用するパイプ長が長く、パイプ材を多く使用するといった欠点がある。さらには、座を垂直方向に回動させてネスティングする際に、脚部全体が前方に大きく張り出した状態で露出するため、見栄えがよくないといった欠点があった。 Such a chair has a drawback in that the molding process is complicated and expensive because it requires a process of bending the leg pipe substantially in a substantially right-angle direction in order to mold the leg member into a gate shape. In particular, there is a drawback that the pipe length used for the gate-shaped leg member is long and a large amount of pipe material is used. Furthermore, when nesting is performed by pivoting the seat in the vertical direction, the entire leg portion is exposed in a state of protruding greatly forward, and thus there is a disadvantage that it does not look good.
　他方、特許文献２に記載の前後方向に積み重ね自在な椅子の構成は、側面視で前脚と後脚とが交わるようにそれぞれ傾斜させ、前脚をさらに上方に延長させるとともに当該前脚の上方に背凭れを取り付け、後脚を上方へと延長させるとともに当該後脚の上方に肘掛けを形成する構成である。この場合、左右の前脚と後脚との交差部分に水平杆を設けるとともに座を回動自在に軸支する構成であり、座の支持と回動部分とを１つの水平杆で行うため、強度の高い水平杆を要し、かつ、回動機構が座を水平に止めるためのストッパ機構を要する。 On the other hand, the configuration of the chair that can be stacked in the front-rear direction described in Patent Document 2 is tilted so that the front legs and the rear legs cross each other in a side view, and the front legs are further extended upward, and the backrest is placed above the front legs. Is attached, the rear leg is extended upward, and an armrest is formed above the rear leg. In this case, a horizontal rod is provided at the intersection between the left and right front legs and the rear leg and the seat is pivotally supported. The seat is supported and rotated by one horizontal rod. And a stopper mechanism for the rotating mechanism to stop the seat horizontally.
　また、上記何れの構成も、椅子の脚部が座の左右側面から垂下しているため、脚部の露出が大きく、脚杆に物がぶつかり傷等がつきやすいといった問題があった。また、通常のパイプ椅子との外見的な違いが小さいことから、意匠的な斬新さが感じられにくく、特に、使用者にとって座が回動自在でありネスティング可能であることが認識しづらいといった問題があった。 Also, in any of the above configurations, the leg of the chair hangs down from the left and right side surfaces of the seat, so that there is a problem that the leg is exposed to a large amount and objects are easily hit and damaged. In addition, since the difference in appearance from a normal pipe chair is small, it is difficult to feel the novelty of the design, and in particular, it is difficult for the user to recognize that the seat is pivotable and can be nested. was there.
　これに対して、垂直な支柱の下端より放射状に設けた脚からなる、ネスティング可能な椅子が開示されている。例えば、特許文献３に示す椅子は、座の下方から垂直に立設された支柱の下端から、放射状に等角度で５本の脚が均等に設けられ、２本の後脚の間に、後方の椅子における３本の前脚のうち中央の前脚を挿入する構成である。この場合、奇数本の脚を等角度で設けた構成であり、椅子の前後で脚の位置を異ならせしめ、複数の脚の間に１本の脚を入り込ませて、前後方向に重ね合わせる構成である。このため、当該構成においては脚同士がぶつかりやすく重ね合わせが難しいといった欠点がある。 On the other hand, a chair capable of nesting is disclosed, which is composed of legs provided radially from the lower end of a vertical column. For example, in the chair shown in Patent Document 3, five legs are evenly provided at equal angles radially from the lower end of a support column that is erected vertically from below the seat, and between the two rear legs, It is the structure which inserts the center front leg among the three front legs in the chair. In this case, an odd number of legs are provided at an equal angle, the positions of the legs are made different between the front and back of the chair, and one leg is inserted between a plurality of legs and overlapped in the front-rear direction. is there. For this reason, this configuration has the disadvantage that the legs collide with each other and it is difficult to superimpose them.
　また、見た目にもネスティングが可能な椅子であることが認識しづらく、さらに、前後方向に重ねた状態であっても、複数の脚部が複雑に絡み合うため、椅子の引き出し方が少しでも横にずれると、脚同士がぶつかってしまい上手く引き離せないといった問題がある。 In addition, it is difficult to recognize that the chair can be nested, and even if the chairs are stacked in the front-rear direction, the legs are intertwined in a complex manner, so the chair can be pulled out sideways even a little. If they are displaced, there is a problem that the legs collide with each other and cannot be separated well.
　さらに、特許文献４の構成は、座の下方に立設した垂直な支柱の下端から、放射状に水平方向の脚を有し、かつ前脚と後脚との高さを変えることにより、後方の椅子の前脚を、前方の椅子の後脚の下方に収納する構成である。この場合、支柱の下端から水平方向かつ放射状に設けた脚構成であり、さらには、支柱部分が回転自在なため、前後の椅子を重ねるためには、脚を正位置に戻す必要がある。 Furthermore, the configuration of Patent Document 4 includes a chair in the rear by having horizontal legs radially from the lower end of a vertical support column standing below the seat and changing the height of the front and rear legs. The front leg is stored below the rear leg of the front chair. In this case, the leg structure is provided horizontally and radially from the lower end of the support column. Furthermore, since the support column part is rotatable, it is necessary to return the leg to the normal position in order to overlap the front and rear chairs.
　何れにせよ、上記文献においては、座の下面に垂直に設けた支柱の外周から放射状に脚を設ける構成であり、支柱を介して脚が接地する構成のため、着座時における安定性が低く、脚を大きく広げて支柱を支持する必要がある。また、支柱から放射状に延設する複数の脚における隙間へと他方の椅子の脚を入れ込むため、ネスティングが難しいといった欠点がある。さらには、ネスティングが可能な椅子であることを脚の外観形状で認識しづらく、特に、前後の椅子を重ね合わせた状態で、椅子の脚が少しでも横方向にずれると、椅子を引き出す際に、脚同士がぶつかってしまい、後方の椅子の前脚が、前方の椅子の後脚の下方にはまり込んでしまうため、椅子を引き離すために、後方の椅子を持ち上げる必要があるといった手間を生じていた。 In any case, in the above document, the legs are provided radially from the outer periphery of the support column provided perpendicularly to the lower surface of the seat, and the legs are grounded via the support column, so the stability at the time of sitting is low, It is necessary to support the column with a wide leg. Moreover, since the leg of the other chair is inserted into the gaps in the plurality of legs extending radially from the support column, there is a drawback that nesting is difficult. In addition, it is difficult to recognize that the chair can be nested by the appearance of the legs, especially when the chair legs are slightly displaced laterally with the front and back chairs overlapped, The legs collided and the front legs of the chair in the back got stuck under the rear legs of the chair in the front. .
　また、上記文献においては、前後一方向からのネスティングを想定したものであり、椅子のネスティング時に、ネスティングする前後一方向へと脚部を揃えて並べる必要があった。 Also, the above document assumes nesting from one direction in the front and back, and when nesting a chair, it is necessary to align the legs in one direction before and after nesting.

　本発明の椅子１は、図２に示すように、座３０および背１０を支持する脚部２０における水平杆２３の略中央から、前方かつ左右に傾斜して設けられた前脚２１と、後方かつ左右に傾斜して設けられた後脚２２とを有し、それぞれの脚２１，２２の下端には、脚端具２６を介してキャスター２８が取り付けられる。特に、後脚２２の内側には、内方へと突出する当接部材２９が取り付けられ、後述する、複数の椅子１を前後方向に重ねた際に、後方の椅子１の前脚２１が、後脚２２に設けた当接部材２９に当接するため、前後の椅子１の位置決めを容易に行うことが可能である。 Below, the structure of the chair 1 of this invention is explained in full detail.
As shown in FIG. 2, the chair 1 according to the present invention includes a front leg 21 that is inclined forward and left and right from the approximate center of the horizontal rod 23 in the leg portion 20 that supports the seat 30 and the back 10, The caster 28 is attached to the lower ends of the legs 21 and 22 via the leg end devices 26. In particular, an abutting member 29 that protrudes inward is attached to the inner side of the rear leg 22, and when a plurality of chairs 1, which will be described later, are stacked in the front-rear direction, the front leg 21 of the rear chair 1 is Since it abuts against the abutting member 29 provided on the leg 22, the front and back chairs 1 can be easily positioned.
　脚部２０における水平杆２３の左右には、さらに後方へと延設される左右杆２４を有し、左右杆２４の端部には、板状の取付部材２５が形成されている。そして、取付部材２５の外側へと背１０と肘掛け４０とを一体に取り付けるとともに、取付部材２５の内側へと、座３０を上下方向へと回転自在に軸支する構成である。 On the left and right sides of the horizontal rod 23 in the leg portion 20, there are left and right rods 24 extending rearward, and plate-like mounting members 25 are formed at the ends of the left and right rods 24. Then, the back 10 and the armrest 40 are integrally attached to the outside of the attachment member 25, and the seat 30 is rotatably supported in the vertical direction to the inside of the attachment member 25.
　すなわち、背１０の左右からは下方へと、板状の取付部１２が延設され、取付部１２の内面および外面にはそれぞれ凹部１３が形成されている。他方、肘掛け４０の下方には、内面に凸部４２が形成されるとともに外面に凹部４３が形成されている。そして、肘掛け４０の凸部４２を、背１０における取付部１２の外面における凹部１３に取り付け、さらに、背１０における取付部１２の内面における凹部１３を、脚部２０における左右杆２４に形成された取付部材２５へと取り付けて、ビス等により、これらを取付部材２５へと一体に固定する構成である。さらに、肘掛け４０の外面に形成された凹部４３へとカバー部材４５を取り付けることにより、ビス等の部品を覆い隠す構成である。 That is, a plate-like attachment portion 12 extends downward from the left and right sides of the spine 10, and concave portions 13 are formed on the inner surface and the outer surface of the attachment portion 12, respectively. On the other hand, below the armrest 40, a convex portion 42 is formed on the inner surface and a concave portion 43 is formed on the outer surface. And the convex part 42 of the armrest 40 was attached to the recessed part 13 in the outer surface of the attaching part 12 in the back 10, and also the recessed part 13 in the inner surface of the attaching part 12 in the back 10 was formed in the left and right collar 24 in the leg part 20. It is the structure which attaches to the attachment member 25, and fixes these to the attachment member 25 integrally with a screw etc. Further, the cover member 45 is attached to the concave portion 43 formed on the outer surface of the armrest 40 to cover the parts such as screws.
　また、座３０は、座面３１および座面３１を載置する座板３２とからなり、座板３２の左右後方には、上方へと突出する軸受け３４を有する。そして、左右杆２４の取付部材２５に形成された軸孔へと座３０における座板３２の軸受け３４を軸支することにより、図３に示すように、座３０の後方を軸に水平状態と垂直状態とに回動させることが可能である。 Further, the seat 30 includes a seat surface 31 and a seat plate 32 on which the seat surface 31 is placed, and has a bearing 34 projecting upward on the left and right rear sides of the seat plate 32. Then, by supporting the bearing 34 of the seat plate 32 in the seat 30 into the shaft hole formed in the mounting member 25 of the left and right rod 24, as shown in FIG. It is possible to rotate to a vertical state.
　すなわち、座３０の水平状態から上方へと回動し、座３０と背１０とが向き合い当接する位置において座３０の垂直状態となり、他方、座３０の垂直状態から下方へと回動し、座３０の下面における座板３２の窪み３３が、脚部２０の水平杆２３に載置される位置において、座３０が水平状態となる。そして、本発明の椅子１は、座３０を垂直状態に跳ね上げた状態で、図４に示すように、複数の椅子１を前後方向に重ね合わせる構成である。 That is, the seat 30 is rotated upward from the horizontal state, and the seat 30 is in the vertical state at the position where the seat 30 and the back 10 face each other, and on the other hand, the seat 30 is rotated downward from the vertical state. The seat 30 is in a horizontal state at a position where the recess 33 of the seat plate 32 on the lower surface of the seat 30 is placed on the horizontal rod 23 of the leg portion 20. And the chair 1 of this invention is the structure which piles up the some chair 1 in the front-back direction, as shown in FIG. 4, in the state which raised the seat 30 to the perpendicular state.
　次に、本発明の椅子１における前後方向へのネスティングについて詳述する。
　本発明の椅子１は、前面視において、図５Ａに示すように、前脚２１が後脚２２の内側に位置する構成である。すなわち、図５Ｂに示すように、脚部２０における左右一対の前脚２１を水平杆２３の中央付近から前方かつ左右方向へと延設し、他方、左右一対の後脚２２を、前脚２１の左右外方から後方かつ左右方向へと延設した構成である。特に、前脚２１における左右方向への傾斜角αと、後脚２２における左右方向への傾斜角βとは、水平杆に対する前脚２１の傾斜角αが大となる構成である。そして、前脚２１の傾斜角αが後脚２２の傾斜角βより大のとき、後脚２２の開きが大となる構成である。 Next, nesting in the front-rear direction in the chair 1 of the present invention will be described in detail.
The chair 1 of the present invention has a configuration in which the front leg 21 is positioned inside the rear leg 22 as shown in FIG. 5A in front view. That is, as shown in FIG. 5B, the pair of left and right front legs 21 in the leg portion 20 are extended from the vicinity of the center of the horizontal rod 23 to the front and left and right, while the pair of left and right rear legs 22 are It is the structure extended from the back to the back and the left-right direction. In particular, the inclination angle α of the front leg 21 in the left-right direction and the inclination angle β of the rear leg 22 in the left-right direction are such that the inclination angle α of the front leg 21 with respect to the horizontal heel is large. When the inclination angle α of the front leg 21 is larger than the inclination angle β of the rear leg 22, the rear leg 22 is greatly opened.
　これにより、図６に示すように、脚部２０における前脚２１が、前方の椅子１における後脚２２の間に入り込み、複数の椅子１を前後方向にネスティングすることが可能である。また、左右一対の後脚２２における、上方かつ内側には、内方へと突出する当接部材２９をそれぞれ有し、複数の椅子１を重ね合わせた際に、後方の椅子１における前脚２１が、前方の椅子１における後脚２２の当接部材２９に当接するため、前後の椅子１の間隔を調節することが可能である。 As a result, as shown in FIG. 6, the front legs 21 of the leg portions 20 enter between the rear legs 22 of the front chair 1, and the plurality of chairs 1 can be nested in the front-rear direction. In addition, the pair of left and right rear legs 22 has an abutting member 29 projecting inward on the upper side and the inner side, and when the plurality of chairs 1 are overlapped, the front legs 21 in the rear chair 1 are In order to contact the contact member 29 of the rear leg 22 in the front chair 1, the distance between the front and rear chairs 1 can be adjusted.
　すなわち、図７に示すように、複数の椅子１を前後方向に重ね合わせた際に、当接部材２９が、後方の椅子１における前脚２１の上方に当接して、前後方向に複数の椅子１を重ね合わせた際の椅子同士の間隔を決めることが可能であり、図８に示すように、複数の椅子１をネスティングさせた際に、最前方の椅子１の後脚２２の当接部材２９に、中央の椅子１の前脚２１が当接して、椅子同士の間隔が固定され、さらに、中央の椅子１の後脚２２の当接部材２９に、最後方の椅子１の前脚２１が当接して、これらの間隔が決まる構成である。 That is, as shown in FIG. 7, when the plurality of chairs 1 are overlapped in the front-rear direction, the contact member 29 abuts above the front leg 21 in the rear chair 1 and the plurality of chairs 1 in the front-rear direction. It is possible to determine the interval between the chairs when the chairs are overlapped. As shown in FIG. 8, when the plurality of chairs 1 are nested, the contact member 29 of the rear leg 22 of the foremost chair 1 is used. In addition, the front legs 21 of the central chair 1 come into contact with each other, the distance between the chairs is fixed, and the front legs 21 of the rearmost chair 1 come into contact with the contact members 29 of the rear legs 22 of the central chair 1. Thus, these intervals are determined.
　これにより、前後の椅子１の間隔を簡単に調整することが可能であり、さらには、脚杆同士が直接当接して脚２１，２２が傷付くことを防止する効果がある。さらには、前方の椅子１における後脚２２と、後方の椅子１における前脚２１とが、絡み合ってしまうことを防止することが可能であり、前後の椅子１を簡単かつ確実に引き離すことが可能である。さらには、前後の椅子１が決まった間隔をもって整然と整列するため、ネスティング時の見た目がきれいといった効果がある。 This makes it possible to easily adjust the distance between the front and rear chairs 1 and to prevent the legs 21 and 22 from being damaged by the direct contact between the leg rods. Furthermore, it is possible to prevent the rear legs 22 of the front chair 1 and the front legs 21 of the rear chair 1 from being entangled, and the front and rear chairs 1 can be easily and reliably separated. is there. Furthermore, since the front and rear chairs 1 are regularly arranged at a predetermined interval, there is an effect that the appearance at the time of nesting is beautiful.
　特に、本発明の椅子１は、座３０の下面を脚部２０の水平杆２３により受ける構成であり、かつ前後の脚２１，２２が略４５°の角度βをもって直線的に設けられるから、水平杆２３にかかる荷重を前後方向かつ左右方向にバランスよく均一に分散させることが可能である。さらには、直線状の脚２１，２２を用いることにより複雑な曲げ工程を要さず、低コストで脚部２０を成型することが可能である。 In particular, the chair 1 of the present invention is configured such that the lower surface of the seat 30 is received by the horizontal rod 23 of the leg portion 20 and the front and rear legs 21 and 22 are linearly provided with an angle β of approximately 45 °. It is possible to distribute the load applied to the ridge 23 uniformly in a well-balanced manner in the front-rear direction and the left-right direction. Furthermore, by using the straight legs 21 and 22, it is possible to mold the leg portion 20 at low cost without requiring a complicated bending process.
　そして、本発明の椅子１は、図９に示すように、複数の椅子１を前後方向に重ね合わせた際にも、前脚２１，２１同士および後脚２２，２２同士がきれいに整列するため見た目もよく、さらには、使用者にとって、前後方向に密に重なり合う椅子１の引き離し方向が容易に認識できる効果がある。 As shown in FIG. 9, the chair 1 of the present invention also has the appearance that the front legs 21 and 21 and the rear legs 22 and 22 are neatly aligned even when the plurality of chairs 1 are overlapped in the front-rear direction. Moreover, there is an effect that the user can easily recognize the pulling direction of the chair 1 that overlaps closely in the front-rear direction.
　なお、上記例では、前脚２１が後脚２２より内側に位置する例を示したが、これに限らず、図１０に示すように、後脚２２が前脚２１より内側に位置する構成であってもよく、すなわち、前脚２１の開きが大であってもよい。何れにせよ、複数の椅子１を前後方向に連続して重ね合わせることが可能な脚構成であれば、適宜脚構成を採用してもよい。 In the above example, the example in which the front leg 21 is positioned inside the rear leg 22 has been shown. However, the present invention is not limited to this, and the rear leg 22 is positioned inside the front leg 21 as shown in FIG. In other words, the opening of the front leg 21 may be large. In any case, any leg configuration may be adopted as long as it is a leg configuration capable of continuously superimposing a plurality of chairs 1 in the front-rear direction.
　この場合、前脚２１，２１における左右方向への傾斜角αと、後脚２２，２２における左右方向への傾斜角βは、前脚２１，２１の傾斜角αが大であり、前脚２１，２１間の幅Ｘが後脚２２，２２間の幅Ｙより広いため（Ｘ＞Ｙ）、着座者の足元の空間が広く取れる効果がある。 In this case, the inclination angle α of the front legs 21, 21 in the left-right direction and the inclination angle β of the rear legs 22, 22 in the left-right direction are large, and the inclination angle α of the front legs 21, 21 is large. Is wider than the width Y between the rear legs 22 and 22 (X> Y), so that there is an effect that a space for the feet of the seated person can be widened.
　よって、着座者が足を折り曲げて、座３０の下方に足元が入り込んでも、着座者の足が椅子の脚部２０にぶつかりにくい効果がある。また、この場合においても、図１１に示すように、椅子１の前脚２１，２１間に、重ねあわせる椅子１の後脚２２，２２が入り込み、複数の椅子同士を密に重ね合わせることが可能である。 Therefore, even if the seated person bends his / her foot and the foot enters the lower side of the seat 30, the seated person's foot is less likely to hit the leg 20 of the chair. Also in this case, as shown in FIG. 11, the rear legs 22 and 22 of the chair 1 to be overlapped enter between the front legs 21 and 21 of the chair 1 so that a plurality of chairs can be closely overlapped with each other. is there.
　さらには、脚部２０の水平杆２３より延設する後脚２２が、前脚２１の左右（外側）から延設する例を示したが、これに限らず、前脚２１の直後から後脚２２が延設してもよく、前脚２１における、左右方向への傾斜角と、後脚２２における、左右方向への傾斜角とを異ならせ、後脚２２または前脚２１の何れかの傾斜角を大とすることにより、前面視において、脚部２０の下方にかけて、後脚２２または前脚２１が外側に位置する構成であってもよい。 Furthermore, although the rear leg 22 extended from the horizontal rod 23 of the leg part 20 showed the example extended from right and left (outside) of the front leg 21, not only this but the rear leg 22 immediately after the front leg 21 is shown. The tilt angle of the front leg 21 in the left-right direction may be different from the tilt angle of the rear leg 22 in the left-right direction, so that either the rear leg 22 or the front leg 21 has a large tilt angle. By doing so, the rear leg 22 or the front leg 21 may be positioned outside the leg portion 20 in front view.
　以上のように、本発明の椅子１は、前後方向にスタッキングが可能な椅子１において、意匠性が高くかつ少ない部材構成により効率的かつ安定的な支持構成を有する椅子１を提供することが可能である。特に、脚部２０における前脚２１と後脚２２とが水平杆２３の略中央から下方にかけて放射状に延設することで、少ない部材で効果的に座３０を支持することが可能であり、さらには、水平杆２３の左右に背１０や座３０のみならず肘掛け４０等の各部材を効率的に支持することが可能である。また、最も荷重のかかる水平杆２３から脚部２０が放射状に延設されるため、着座時の安定性が高く、着座状態での椅子１の移動もスムースに行うことが可能である。 As described above, the chair 1 of the present invention is a chair 1 that can be stacked in the front-rear direction, and can provide the chair 1 that has an efficient and stable support configuration with a high design and a small number of member configurations. It is. In particular, the front leg 21 and the rear leg 22 in the leg portion 20 extend radially from the substantially center of the horizontal rod 23 to the lower side, so that the seat 30 can be effectively supported with a small number of members. The members such as the armrests 40 as well as the back 10 and the seat 30 can be efficiently supported on the left and right of the horizontal rod 23. Moreover, since the leg part 20 is extended radially from the horizontal rod 23 to which the most load is applied, the stability at the time of sitting is high, and the movement of the chair 1 in the sitting state can be performed smoothly.
　本発明の実施例２の椅子１０１が好適に用いられる一例としては、図１２に示すように、背１１０と座１３０とを有し、背１１０と座１３０が左右方向に回転可能な椅子１０１であって、さらに、座１３０を上下方向に跳ね上げ自在な椅子１０１である。そして、この椅子１０１は、後述する、座１３０を上方に跳ね上げた状態で、水平方向に重ね合わせる（ネスティング）ことが可能な椅子１０１であり、特に、前後方向と左右方向との複数の方向から椅子１０１をネスティングすることが可能である。 As an example in which the chair 101 according to the second embodiment of the present invention is preferably used, as shown in FIG. 12, the chair 101 has a back 110 and a seat 130, and the back 110 and the seat 130 are rotatable in the left-right direction. Further, the chair 101 is a chair 101 that can freely flip up the seat 130 in the vertical direction. The chair 101 is a chair 101 that can be overlapped (nested) in the horizontal direction in a state in which a seat 130 is flipped upward, which will be described later, and in particular, a plurality of directions including a front-rear direction and a left-right direction. The chair 101 can be nested.
　以下に、本発明の椅子１０１の構成について詳述する。
　まず、本発明の椅子における脚部１２０は、図１３に示すように、楕円筒形の脚基部１２５から斜め下方へと放射状に延設される左右一対の前脚１２１，１２２と、左右一対の後脚１２３，１２４との計４本の脚を有し、それぞれの脚１２１，１２２，１２３，１２４の下端部分には、脚端具１２７を介してキャスター１２８が取り付けられる。 Below, the structure of the chair 101 of this invention is explained in full detail.
First, as shown in FIG. 13, the leg 120 in the chair of the present invention includes a pair of left and right front legs 121 and 122 extending radially downward from an elliptical cylindrical leg base 125 and a pair of left and right rear legs. The leg has a total of four legs 123 and 124, and a caster 128 is attached to a lower end portion of each leg 121, 122, 123, and 124 via a leg end tool 127.
　これら脚１２１，１２２，１２３，１２４は、後述する、非対称状に形成されており、前面視における、前後何れかの左右一対の脚（１２１，１２２または１２３，１２４）が、他の脚（１２３，１２４または１２１，１２２）の内方に位置し、左右何れかの前後一対の脚（１２１，１２３または１２２，１２４）が、側面視における、他の脚（１２２，１２４または１２１，１２３）の内方に位置することで、複数方向からのネスティングが可能である。 These legs 121, 122, 123, and 124 are formed in an asymmetrical shape, which will be described later, and when viewed from the front, either a pair of left and right legs (121, 122 or 123, 124) is the other leg (123). , 124 or 121, 122), and a pair of left and right front and rear legs (121, 123 or 122, 124) are connected to other legs (122, 124 or 121, 123) in a side view. By being positioned inward, nesting from a plurality of directions is possible.
　脚部１２０における脚基部１２５の略中央には、軸孔１２６が形成されており、軸孔１２６に、後述する、背板１１１および肘掛け１１５と座板１３５を支持する水平杆１３２が左右方向へと回動自在に軸支される。 A shaft hole 126 is formed substantially at the center of the leg base 125 in the leg 120, and a horizontal rod 132 that supports a back plate 111, an armrest 115, and a seat plate 135, which will be described later, in the shaft hole 126 in the left-right direction. And pivotally supported.
　水平杆１３２は、脚基部１２５の軸孔１２６へと軸支される支軸１３１を有し、さらには、水平杆１３２の左右より後方に向けて延設する左右杆１３３と、左右杆１３３の端部より立設する板状の取付板１３４とを有する。取付板１３４は、座板１３５を上下方向に傾倒自在に軸支するための軸孔１３９や背板１１１および肘掛け１１５を取り付けるための複数のねじ孔が形成されている。 The horizontal rod 132 includes a support shaft 131 that is pivotally supported by the shaft hole 126 of the leg base 125, and further includes a left and right rod 133 that extends from the left and right of the horizontal rod 132 toward the rear, and a left and right rod 133. And a plate-like mounting plate 134 erected from the end. The mounting plate 134 is formed with a shaft hole 139 for pivotally supporting the seat plate 135 in a tiltable manner in the vertical direction, and a plurality of screw holes for mounting the back plate 111 and the armrest 115.
　そして、後述する、座１３０を上下方向に傾倒自在に軸支すべく、水平杆１３２における左右の取付板１３４に形成された軸孔１３９へと、座板１３５の左右後端に形成された軸孔１３６をもって上下方向へと回動自在に軸支する構成である。また、座板１３５の上面にクッション性を有する座面１３７を固定する。 Then, a shaft formed at the left and right rear ends of the seat plate 135 to a shaft hole 139 formed in the left and right mounting plates 134 of the horizontal rod 132 in order to pivotally support the seat 130 to be tilted in the vertical direction, which will be described later. It is the structure which pivotally supports with the hole 136 so that rotation to an up-down direction is possible. Further, a seat surface 137 having cushioning properties is fixed to the upper surface of the seat plate 135.
　他方、水平杆１３２の取付板１３４へと、背板１１１の下方に延設する板状の取付部１１２の凹部１１３を係合し、さらに、背板１１１の取付部１１２の外面に形成された凹部１１４へと、肘掛け１１５の内面に形成された凸部１１６を係合し、これら背板１１１および肘掛け１１５を水平杆１３２の取付板１３４へとビス等により一体に固定した後、肘掛け１１５の外面に形成された凹部１１７へとカバー部材１１８を取り付けることでビス等の部品を覆い隠す構成である。 On the other hand, the concave portion 113 of the plate-like attachment portion 112 extending below the back plate 111 is engaged with the attachment plate 134 of the horizontal rod 132, and further formed on the outer surface of the attachment portion 112 of the back plate 111. A convex portion 116 formed on the inner surface of the armrest 115 is engaged with the concave portion 114, and the back plate 111 and the armrest 115 are integrally fixed to the mounting plate 134 of the horizontal rod 132 with a screw or the like. The cover member 118 is attached to the concave portion 117 formed on the outer surface to cover the parts such as screws.
　これにより、図１４に示すように、脚部１２０の上方において、背板１１１および肘掛け１１５と座板１３５とを、水平杆１３２とともに左右方向へと回動可能（図中、矢印ａ）である。また、座板１３５と背板１１１とが向かい合う垂直状態と、座板１３５の裏面に設けられた窪みからなる座受け１３８が水平杆１３２に載置される水平状態との間で、座板１３５を上下方向に傾倒可能（図中、矢印ｂ）である。 As a result, as shown in FIG. 14, the back plate 111, the armrest 115, and the seat plate 135 can be rotated in the left-right direction together with the horizontal rod 132 above the leg portion 120 (arrow a in the figure). . Further, the seat plate 135 is between a vertical state in which the seat plate 135 and the back plate 111 face each other and a horizontal state in which the seat receiver 138 formed of a depression provided on the back surface of the seat plate 135 is placed on the horizontal rod 132. Can be tilted in the vertical direction (arrow b in the figure).
　特に、本発明の椅子１０１は、脚部１２０が、座１３０の下部に位置する脚基部１２５より放射状かつ非対称に延設されており、座板１３５を垂直状態に起立させることで、図１５に示すように、複数の椅子１０１を前後方向または左右方向に重ね合わせることが可能である。 In particular, in the chair 101 of the present invention, the leg portion 120 is extended radially and asymmetrically from the leg base portion 125 located at the lower portion of the seat 130, and the seat plate 135 is erected in a vertical state, so that FIG. As shown, a plurality of chairs 101 can be overlapped in the front-rear direction or the left-right direction.
　すなわち、脚部１２０は、図１６に示すように、平面視において、脚基部１２５から傾斜して直線状の脚１２１，１２２，１２３，１２４がそれぞれ非対称に形成されており、かつ、前脚１２１，１２２は後脚１２３，１２４の内側に位置し、前後の右脚１２２，１２４は前後の左脚１２１，１２３の内側に位置する構成である。 That is, as shown in FIG. 16, the leg portion 120 is inclined from the leg base portion 125 in a plan view, and linear legs 121, 122, 123, 124 are formed asymmetrically, and the front legs 121, 122 is positioned inside the rear legs 123 and 124, and the front and rear right legs 122 and 124 are positioned inside the front and rear left legs 121 and 123.
　これにより、後述する、脚部１２０を前後方向（図中、Ｘ方向）に重ね合わせる場合と、左右方向（図中、Ｙ方向）に重ね合わせる場合との、２方向からのネスティングが可能である。このとき、所定のネスティングの方向へと図示しない背１１０および座１３０を回転させる必要があることはいうまでもない（図中、点線ａ）。 Thereby, nesting from two directions, which is described later, when the leg portions 120 are overlapped in the front-rear direction (X direction in the drawing) and in the left-right direction (Y direction in the drawing), is possible. . At this time, needless to say, it is necessary to rotate the spine 110 and the seat 130 (not shown) in a predetermined nesting direction (dotted line a in the figure).
　例えば、本発明の椅子１０１を前後方向（Ｘ方向）にネスティングする場合、図１７Ａに示すように、脚部１２０の前面視において、脚基部１２５に対する前脚１２１，１２２の傾斜角度αが後脚１２３，１２４の傾斜角度βより大（α＞β）であって、前脚１２１，１２２の略下半分が後脚１２３，１２４の内側に位置（ｘ＜ｘ’）するため、図１７Ｂに示すように、脚部１２０の平面視において、複数の椅子の前脚１２１，１２２の下半分を、複数の椅子の後脚１２３，１２４の間に挿入して順次ネスティングすることが可能である。よって、図１８に示すように、複数の椅子１０１を前後方向（Ｘ方向）にネスティングすることが可能である。 For example, when the chair 101 of the present invention is nested in the front-rear direction (X direction), as shown in FIG. 17A, the inclination angle α of the front legs 121 and 122 with respect to the leg base 125 in the front view of the leg 120 is the rear leg 123. , 124 is larger than the inclination angle β (α> β), and the substantially lower half of the front legs 121, 122 is positioned inside the rear legs 123, 124 (x <x ′), so that as shown in FIG. In plan view of the leg 120, the lower halves of the front legs 121, 122 of the plurality of chairs can be inserted between the rear legs 123, 124 of the plurality of chairs and sequentially nested. Therefore, as shown in FIG. 18, it is possible to nest a plurality of chairs 101 in the front-rear direction (X direction).
　他方、図１９Ａに示すように、脚部１２０の側面視において、脚基部１２５に対する右脚１２２，１２４の傾斜角度α’が左脚１２１，１２３の傾斜角度β’より大（α’＞β’）であって、右脚１２２，１２４の略下半分が左脚１２１，１２３の内側に位置（ｙ＜ｙ’）するため、図１９Ｂに示すように、脚部１２０の平面視において、複数の椅子１０１の右脚１２２，１２４の下半分を、複数の椅子１０１の左脚１２１，１２３の間に挿入してネスティングすることが可能である。よって、図２０に示すように、複数の椅子１０１を左右方向にネスティングすることが可能である。 On the other hand, as shown in FIG. 19A, in the side view of the leg 120, the inclination angle α ′ of the right legs 122, 124 with respect to the leg base 125 is larger than the inclination angle β ′ of the left legs 121, 123 (α ′> β ′). ) And the substantially lower half of the right legs 122 and 124 is located inside the left legs 121 and 123 (y <y ′), and therefore, as shown in FIG. The lower half of the right legs 122 and 124 of the chair 101 can be inserted between the left legs 121 and 123 of the plurality of chairs 101 for nesting. Therefore, as shown in FIG. 20, a plurality of chairs 101 can be nested in the left-right direction.
　このように、本発明の椅子１０１は、前後方向のみならず左右方向へもネスティングすることが可能である。よって、ネスティング時に脚部１２０をネスティング方向に揃える手間を省き、複数の方向からネスティング可能な使用性の高い椅子１０１を提供することが可能である。 Thus, the chair 101 of the present invention can be nested not only in the front-rear direction but also in the left-right direction. Therefore, it is possible to provide a highly usable chair 101 that can be nested from a plurality of directions, without the need to align the legs 120 in the nesting direction during nesting.
　上記例では、前後方向のネスティングにおいて、前方の脚間ｘを後方の脚間ｘ’より小とした例（ｘ＜ｘ’）を示したが、前方の脚間ｘを後方の脚間より大（ｘ＞ｘ’）として、複数の椅子１０１を前後方向にネスティングする構成であってもよい。同様に、左右方向のネスティングにおいて、上記例では、右方の脚間ｙを左方の脚間ｙ’より小とした例（ｙ＜ｙ’）を示したが、右方の脚間ｙを左方の脚間ｙ’より大（ｙ＞ｙ’）として、複数の椅子を左右方向にネスティングする構成であってもよい。 The above example shows an example in which the front leg x is smaller than the rear leg x ′ in the front-rear direction nesting (x <x ′), but the front leg x is larger than the rear leg. (X> x ′) may be configured such that a plurality of chairs 101 are nested in the front-rear direction. Similarly, in the left-right nesting, the above example shows an example in which the right leg interval y is smaller than the left leg interval y ′ (y <y ′). A configuration may be adopted in which a plurality of chairs are nested in the left-right direction as being larger than the left leg y ′ (y> y ′).
　さらには、前方の脚間ｘと右方の脚間ｙとのそれぞれの距離を等しくし（ｘ＝ｙ）、かつ、後方の脚間ｘ’と左方の脚間ｙ’とのそれぞれの距離を等しくすることで（ｘ’＝ｙ’）、前後方向Ｘと左右方向Ｙとを区別なくネスティングすることが可能である。これにより、ネスティング時に脚部１２０をネスティング方向に揃える手間をさらに省くことが可能であり、複数の方向からネスティング可能な椅子１０１を提供することが可能である。 Further, the distance between the front leg x and the right leg y is made equal (x = y), and the distance between the rear leg x ′ and the left leg y ′ is made equal. Are equal (x ′ = y ′), the front-rear direction X and the left-right direction Y can be nested without distinction. Thereby, it is possible to further save the trouble of aligning the leg 120 in the nesting direction during nesting, and it is possible to provide the chair 101 that can be nested from a plurality of directions.
　何れにせよ、本発明の椅子１０１における脚部１２０の脚配置を非対称とし、椅子１０１の前面視において、前後何れかの、左右一対の脚が他の左右一対の脚の内方に位置し、かつ、椅子１０１の側面視において、左右何れかの、前後一対の脚が他の前後一対の脚の内方に位置することで、脚部同士を複数方向からネスティング可能な構成とすればよく、脚の形状や配置は特に限定されるものではない。 In any case, the leg arrangement of the leg portion 120 in the chair 101 of the present invention is asymmetrical, and in the front view of the chair 101, the pair of left and right legs is located inside the other pair of left and right legs, And in the side view of the chair 101, either the left or right pair of front and rear legs is positioned inside the other pair of front and rear legs, so that the legs can be configured to be nestable from a plurality of directions, The shape and arrangement of the legs are not particularly limited.
