Description

本発明は、斜面等に手軽に設置でき、安定した座り心地を提供できる腰掛けに関するものである。The present invention relates to a stool that can be easily installed on a slope or the like and can provide a stable sitting comfort.

斜面に設置することを目的とする腰掛け、椅子、及びそれらに類似するものは現在いくつかの種類がある。There are currently several types of stools, chairs, and the like that are intended to be installed on slopes.

下記の特許文献１には、斜面で使える折りたたみ椅子が開示されている。この折りたたみ椅子は、交差する前脚と後脚の一方の脚の中心点をずらす事によって、折りたたみ椅子の脚の接地面と坐面との角度が変えられるため、椅子を設置しようとする斜面の傾斜角に応じて坐面を水平に保つことが出来るように構成されている。
また、下記の特許文献２には、斜面等に座ることができる、前脚杆と後脚杆を枢支した折たたみ椅子が開示されている。この折たたみ椅子の脚杆の下部には、接地台部が揺動自在に設けられている。また、脚杆の下端は先鋭に形成されているとともに、接地台部より下方に進退自在に設けられている。Patent Document 1 below discloses a folding chair that can be used on a slope. In this folding chair, the angle between the ground contact surface and the seating surface of the folding chair leg can be changed by shifting the center point of one of the intersecting front and rear legs. It is configured so that the seating surface can be kept horizontal according to the angle.
Further, Patent Document 2 below discloses a folding chair that can sit on a slope or the like and pivotally support a front leg rod and a rear leg rod. A grounding base is swingably provided at the lower part of the leg rod of the folding chair. Further, the lower end of the leg rod is formed to be sharp and is provided so as to be able to advance and retract downward from the grounding platform.

特開２００５−２９６１８９号公報JP 2005-296189 A 実開平０７−２５８４９号公報Japanese Utility Model Publication No. 07-25849

上記特許文献１のタイプの折りたたみ椅子は、以下に述べる二つの理由から、斜面で使用される椅子としての安定性が十分でなかった。一つ目の理由は、このタイプの椅子は斜面に固定されるわけではなく、単に斜面の上に置かれるにすぎなかった。二つ目の理由は、地面から比較的に離れた位置に座面部があったことと、折りたたみ椅子が軽量であったことにより、着座した状態での重心の位置が高かった。The folding chair of the type described in Patent Document 1 has not been sufficiently stable as a chair used on a slope for the following two reasons. The first reason was that this type of chair was not fixed on the slope, but simply placed on the slope. The second reason was that the position of the center of gravity in the seated state was high because the seat surface part was located relatively far from the ground and the folding chair was lightweight.

特許文献２のタイプでは、脚杆の下部の形状からして、リュックやカバンに気軽に入れるほどコンパクトに折りたたむことは出来なく、携帯に不便だった。また、スポーツ等の観客で混雑した斜面において使用された場合、安定した座面部を提供するために張り出した後脚杆に周囲を歩く人が躓く危険性があった。The type of Patent Document 2 cannot be folded so compactly that it can be easily put in a backpack or a bag because of the shape of the lower part of the leg pad, which is inconvenient to carry. In addition, when used on a crowded slope by a spectator such as a sport, there is a risk that a person walking around the rear leg padding overhangs to provide a stable seating surface.

また、比較的に地面から離れた位置に座面部がある特許文献１と特許文献２のタイプでは、グリーン周りでのゴルフ観戦や外野席での野球観戦等に使用された場合、後ろに位置する観客の視界を妨げる恐れがあった。Further, in the types of Patent Document 1 and Patent Document 2 in which the seat surface portion is relatively far away from the ground, when used for golf watching around the green, baseball watching in an outdoor field seat, etc., the audience located behind There was a risk of obstructing the field of view.

総合的に見て、観戦者で込み合う傾斜地に手軽に持ち込み、周囲の観戦者の迷惑にならない状態で設置でき、なお且つ使用者に安定した座り心地を提供できる携帯用腰掛けは無かった。Overall, there was no portable stool that could be easily brought to an inclined place crowded with spectators, installed without disturbing the surrounding spectators, and provided a stable sitting comfort for the user.

本発明の目的は斯かる課題に鑑みてなされたもので、上記の課題を解決することが出来る腰掛けを提供することである。The object of the present invention has been made in view of such problems, and is to provide a stool that can solve the above problems.

以下、図面を参照して、本発明の一実施形態を説明する。Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

本発明の第１の実施形態を説明する。図１、図２に示すように、腰掛け１は、平面視略矩形状の接地面部形成板２と、平面視略矩形である座面部形成板３と、支持部材５とを有する。接地面部形成板２と座面部形成板３とは、互いに後縁で連結部材４によって開閉可能に結合されている。支持部材５は、一端に形成されたヒンジ状の支持部材上部連結部５ａで、座面部形成板３の下面に開閉可能に連結しており、支持部材５の他端が接地面部形成板２の上面に形成された溝状の支持部材係止ミゾ部６に係止されることにより、接地面部形成板２と座面部形成板３との二つの面で作る角度が所定の角度αに保持される。A first embodiment of the present invention will be described. As shown in FIGS. 1 and 2, the stool 1 includes a ground surface portion forming plate 2 having a substantially rectangular shape in plan view, a seat surface portion forming plate 3 having a substantially rectangular shape in plan view, and a support member 5. The ground surface portion forming plate 2 and the seat surface portion forming plate 3 are coupled to each other at the rear edge by a connecting member 4 so as to be opened and closed. The support member 5 is a hinge-like support member upper connecting portion 5 a formed at one end, and is connected to the lower surface of the seat surface portion forming plate 3 so as to be openable and closable, and the other end of the support member 5 is the ground surface portion forming plate 2. The angle formed by the two surfaces of the ground surface portion forming plate 2 and the seat surface portion forming plate 3 is maintained at a predetermined angle α by being locked to the groove-like support member locking groove portion 6 formed on the upper surface. The

支持部材５が支持部材係止ミゾ部６に係止された状態を確実に保持するために、図２で示すように、面ファスナーによる留め具材７が、接地面部形成板前縁１１の留め具材結合部７ａに結合され、留め具材係止部７ｂが座面部形成板前縁１１′に形成されている。In order to reliably hold the state in which the support member 5 is locked to the support member locking groove portion 6, as shown in FIG. Coupled to the material coupling portion 7a, a fastener material locking portion 7b is formed on the seat surface portion forming plate front edge 11 '.

図３に示すように、接地面部形成板２と座面部形成板３との面で作る角度αを支持部材５が保持した状態で、斜面に腰掛け１を設置すると、略水平状態の座面部形成板３に腰を掛ける事が出来る。As shown in FIG. 3, when the stool 1 is installed on the slope in a state where the support member 5 holds the angle α formed by the surfaces of the ground surface portion forming plate 2 and the seat surface portion forming plate 3, the seat surface portion is formed in a substantially horizontal state. You can sit on the board 3.

支持部材係止ミゾ部６にはミゾが複数形成されており、異なったミゾに支持部材５を係止することで、座面部形成板３と接地面部形成板２とを異なる角度で固定することが可能となり、結果的に勾配の異なった斜面に対応して、座面部形成板３がより水平に近い状態になるように調節して腰掛け１を設置する事が出来る。支持部材係止ミゾ部６のミゾの断面の形状は、図２（ｂ）で示すように、鋸の歯のような略三角形状でも良いし、また図２（ｃ）で示すように略四角形状でも良い。
接地面部形成板２と座面部形成板３とは、合成樹脂で形成され、支持部材５と連結部材４とは、薄くても必要な強度が得られるように、金属で形成されている。A plurality of grooves are formed in the support member locking groove portion 6, and the seating surface portion forming plate 3 and the ground surface portion forming plate 2 are fixed at different angles by locking the support member 5 to different grooves. As a result, it is possible to install the stool 1 by adjusting the seat surface portion forming plate 3 so as to be in a more horizontal state corresponding to slopes having different slopes. The shape of the cross section of the groove of the support member locking groove portion 6 may be a substantially triangular shape such as a saw tooth as shown in FIG. 2 (b), or a substantially square shape as shown in FIG. 2 (c). It may be in shape.
The ground surface portion forming plate 2 and the seat surface portion forming plate 3 are made of synthetic resin, and the support member 5 and the connecting member 4 are made of metal so that necessary strength can be obtained even if they are thin.

図１で示すように、座面部形成板３の下面には、折り畳まれた支持部材５を収納するための、支持部材収納凹部５ｂが形成されている。支持部材５は比較的厚みの薄い金属で形成され、支持部材収納凹部５ｂの凹部は、座面部形成板３の強度を損なわないほどに浅く形成される。As shown in FIG. 1, a support member storage recess 5 b for storing the folded support member 5 is formed on the lower surface of the seat surface portion forming plate 3. The support member 5 is formed of a relatively thin metal, and the recess of the support member storage recess 5b is formed so shallow that the strength of the seat surface portion forming plate 3 is not impaired.

本実施形態によれば、支持部材５を座面部形成板３の下面に折り畳み、腰掛けを閉じ、留め具材７を留め具材係止部７ｂに係止すると、腰掛け１はノート型パソコン程のコンパクトな形状となり、携帯に便利であると同時に、観客で込み合うスペースにも手軽に運び込むことが出来る。According to this embodiment, when the support member 5 is folded on the lower surface of the seat surface portion forming plate 3, the stool is closed, and the fastener material 7 is engaged with the fastener material engagement portion 7b, the stool 1 is as large as a notebook computer. It is compact and convenient to carry, and at the same time it can be easily carried into a crowded space.

また、支持部材５は座面部形成板３の下面に開閉可能に連結しているので、接地面部形成板２を下にして座面部形成板３を上方に押し開くと、支持部材５の下端が重力によって自動的に接地面部形成板２の上面に形成された支持部材係止ミゾ部６近辺に位置するので使い勝手が良い。また、支持部材部５の一端が、腰掛け１の本体に連結しているので、構造的に安定するとともに、腰掛け１の設置および撤去がより簡単になり、また支持部材５の紛失を避ける事が出来る。Further, since the support member 5 is connected to the lower surface of the seat surface portion forming plate 3 so as to be openable and closable, when the seat surface portion forming plate 3 is pushed upward with the ground surface surface forming plate 2 down, the lower end of the support member 5 is Since it is located in the vicinity of the support member locking groove portion 6 formed automatically on the upper surface of the ground surface portion forming plate 2 by gravity, it is easy to use. In addition, since one end of the support member 5 is connected to the body of the stool 1, the structure is stable, and the installation and removal of the stool 1 can be simplified, and the loss of the support member 5 can be avoided. I can do it.

上記実施形態では、支持部材５は、一端が座面部形成板３の下面に連結し、他端が接地面部形成板２の上面に係止されることにより、接地面部形成板２と座面部形成板３との二つの面で作る角度を所定の角度αに保持していたが、支持部材５の連結、係止の形態はこの実施形態に限定されるものではなく、例えば一端が接地面部形成板２の上面に連結し、他端が座面部形成板３の下面に係止してもよいし、両端がそれぞれ接地面部形成板２の上面と座面部形成板３の下面とに形成されたミゾ部に係止し、留め具材７でこの係止状態を保持しても良い。また、接地面部形成板２と座面部形成板３とに形成されたミゾ部が蟻ミゾである場合は、両形成板の側面から紙芝居の紙を差し込む要領で両形成板に係止された支持部材５が、腰掛け１の使用中に外れるという恐れが無いので、留め具７を用い係止状態を保持する必要がない。
なお、ここで連結とは軸支や、枢支や、一定角度に固定すること、あるいは分離させる事の出来ない状態であることを意味し、使用する部品の例として、例えばヒンジのように回転自在に支持する部品や、断面Ｌ字型の金属板で支持部材と座面部形成板とをネジで固定する部品といった部品の例が挙げられる。In the above embodiment, the support member 5 has one end connected to the lower surface of the seat surface portion forming plate 3 and the other end locked to the upper surface of the ground surface portion forming plate 2, thereby forming the ground surface portion forming plate 2 and the seat surface portion. Although the angle formed by the two surfaces with the plate 3 is maintained at a predetermined angle α, the form of connection and locking of the support member 5 is not limited to this embodiment. It may be connected to the upper surface of the plate 2, and the other end may be engaged with the lower surface of the seat surface portion forming plate 3, and both ends are formed on the upper surface of the ground surface portion forming plate 2 and the lower surface of the seat surface portion forming plate 3, respectively. You may latch to a groove part and hold | maintain this latching state with the fastener material 7. FIG. Further, when the groove formed on the ground surface portion forming plate 2 and the seat surface portion forming plate 3 is a ant groove, the support locked to the both forming plates in the manner of inserting the paper from the side surfaces of both forming plates. Since there is no fear that the member 5 will come off during use of the stool 1, it is not necessary to use the fastener 7 to maintain the locked state.
In this case, the connection means that it is in a state where it cannot be fixed to a shaft support, a pivot support, a fixed angle, or separated, and as an example of a part to be used, for example, it rotates like a hinge. Examples include a part that is freely supported and a part that is a metal plate having an L-shaped cross section and that fixes the support member and the seat surface portion forming plate with screws.

上記実施形態では、接地面部形成板２と座面部形成板３とが平面視略矩形の形状をしていたが、接地面部形成板２と座面部形成板３との形状は本実施形態に限定されるものではなく、例えば平面視略台形状であっても良い。また、支持部材５の形態も本実施形態の矩形状に限定されるものではなく、例えば一対の棒状支持部材が、接地面部形成板２の上面の前縁近くの左右に、長手方向（左右幅方向）内側に向かって折り畳み可能に枢着されている形態であっても良い。この場合、座面部形成板３の下面の左右には、棒状支持部材が係止する為の穴部が設けられている。また、接地面部形成板２の上面には、棒状支持部材の収納凹部が設けられている。また、複数対の棒状支持部材が、後縁に向かって平行に設けられており、使用する棒状支持部材の対を選択する事で、腰掛け１を設置する斜面の異なる傾斜角度に対応できるよう構成されている。
棒状支持部材は接地面部形成板２の上面に設けられているので、腰掛け１を設置するために接地面部形成板２を下にして座面部形成板３を開いた時、棒状支持部材がすぐに目に入り、適切な対の棒状支持部材を選び、収納凹部から引き出す事が容易で使い勝手が良い。In the above embodiment, the ground surface portion forming plate 2 and the seat surface portion forming plate 3 have a substantially rectangular shape in plan view, but the shapes of the ground surface portion forming plate 2 and the seat surface portion forming plate 3 are limited to the present embodiment. For example, it may have a substantially trapezoidal shape in plan view. Further, the form of the support member 5 is not limited to the rectangular shape of the present embodiment. For example, a pair of rod-like support members are arranged in the longitudinal direction (left and right width) near the front edge of the upper surface of the ground surface portion forming plate 2. (Direction) It may be a form pivoted so as to be foldable inward. In this case, on the left and right sides of the lower surface of the seat surface portion forming plate 3, holes for locking the rod-like support members are provided. In addition, on the upper surface of the ground surface portion forming plate 2, a storage recess for the bar-shaped support member is provided. Further, a plurality of pairs of rod-like support members are provided in parallel toward the rear edge, and can be adapted to cope with different inclination angles of the slope on which the stool 1 is installed by selecting a pair of rod-like support members to be used. Has been.
Since the rod-shaped support member is provided on the upper surface of the ground plane portion forming plate 2, when the seat plane portion forming plate 3 is opened with the ground plane portion forming plate 2 facing down to install the stool 1, the rod-shaped support member is immediately It is easy to use and easy to pull out from the storage recess by selecting an appropriate pair of rod-shaped support members.

図５に示すように、接地面部形成板２の下面には、滑り止め部材として、地面に差し込まれることで腰掛け１を斜面に固定することの出来る滑り止めピン８が、下方突出状態に複数配置されている。滑り止めピン８は、滑り止めピン８と接地面部形成板５の下面との作る角度βが０°〜９０°の範囲で、接地面部形成板前縁１１の方向のみに折り畳み可能に接地面部形成板２の下面に枢着されている。また、接地面部形成板２の下面には、滑り止めピン収納凹部８ａが設けられている。滑り止めピン８は錆びにくい金属で形成されている。 As shown in FIG. 5, a plurality of anti-slip pins 8, which can fix the stool 1 to an inclined surface by being inserted into the ground, are arranged on the lower surface of the ground contact surface forming plate 2 so as to protrude downward. Has been. The anti-slip pin 8 is foldable only in the direction of the front edge 11 of the ground surface portion forming plate so that the angle β formed by the anti-slip pin 8 and the lower surface of the ground surface portion forming plate 5 is in the range of 0 ° to 90 °. 2 is pivotally attached to the lower surface.
