Description
本発明は、らせん階段に関する。特に同じビル内の異なる階にある部屋を内部でつなぐためのらせん階段が普及しているのは主に、それらが極めて小さい平面積を有するためである。特にここ何十年もの間、そのことは、ますます増え続けている小規模住宅の要求を充分に満たしてきた。 The present invention relates to a spiral staircase. In particular, spiral stairs for connecting rooms on different floors in the same building are popular because they have a very small flat area. Especially over the last decades, it has satisfactorily met the growing demand for small housing.
知られているように、らせん階段は垂直の中心軸を有していて、前記軸に沿って段（steps）が供給され、前記段はその自由端の1つが前記軸に取り付けられている。一連の段は空中にらせんを規定し、前記軸の周囲を移動することにより、人が階段を昇降することができる。段の自由端は通常手すりを支え、前記手すりは階段に沿った動きを円滑にし、使用者をサポートしている。 As is known, a spiral staircase has a vertical central axis, and steps are provided along the axis, one of its free ends being attached to the axis. A series of steps define a helix in the air, and a person can move up and down the stairs by moving around the axis. The free end of the step usually supports the handrail, which facilitates movement along the stairs and supports the user.
上記全てを利用していて使用可能なスペースが限られているとき、標準体格の人にとって、段の幅が減らされた場合、より正確に言うと、階段の中心である中心軸と段の自由端との間の距離が減らされた場合、階段の昇降が多少困難になることは否定できない。 When all of the above are used and the available space is limited, for a standard physique, if the step width is reduced, more precisely, the central axis and the freedom of the step, the center of the stairs If the distance between the ends is reduced, it is undeniable that it is somewhat difficult to move up and down the stairs.
これらの使用は、以下の事実によってさらに困難になっている。コンパクトな面積を有する段を連結するという前記段の配置は、多くの場合、足底、特に階段を降りるときの内足の底、を維持できる表面が減らされるので、移動時に必要な安定性を保証できないことを意味している。 Their use is further complicated by the following facts. The arrangement of the steps, which connect steps with a compact area, often reduces the surface that can maintain the sole, especially the bottom of the inner foot when going down the stairs, so it provides the necessary stability when moving. It means that it cannot be guaranteed.
らせん階段の段の配置は、主に、階段の平面積とライザー（riser）、つまり２つの連続する段を隔てている高さとによると考えることが重要である。平面図において周角（３６０°）により隔てられている２つの段は、平均身長を有する人が高い方の段に頭をぶつけるリスクを冒さずに通過することのできるように、高さに関し、必要なスペース（約２メートル）により隔てられていなければならない。さらに、踊り場は大きな角度を占めるため、前記状況は階段の上端付近で重大な問題となっている。 It is important to consider the arrangement of the steps of the spiral staircase mainly due to the flat area of the staircase and the riser, that is, the height separating two consecutive steps. The two tiers separated by a circumferential angle (360 °) in the plan view, with respect to height, allow a person with average height to pass without risking hitting the higher tier, Must be separated by the required space (approximately 2 meters). Furthermore, since the landing occupies a large angle, the situation is a serious problem near the top of the stairs.
特に、平面積がコンパクトで、直径１３０／１４０ｃｍの円、あるいは、１辺が同様の長さを有する正方形に匹敵する場合、現在の解決策では、ライザーと踏み面との比率に相当する値が、一直線の傾斜により得られる場合と極めて異なり、外足と比較して内足にとって著しく都合が悪くなっている。 In particular, if the flat area is compact, comparable to a circle with a diameter of 130/140 cm, or a square with a similar length on one side, the current solution has a value corresponding to the ratio of riser to tread. This is very different from the case obtained by the straight inclination, which is significantly inconvenient for the inner foot compared to the outer foot.
段が異なる方法で形成されたらせん階段の同様の例がある：特許番号ＤＥ ３１ ４６ １３３は、２種類の段を有するらせん階段であって、各々の段は凹凸部を有しているものの内足をサポートすることのできる面を増やすために互いに補完はしていない、らせん階段を開示している。 There is a similar example of a spiral staircase in which the steps are formed in different ways: Patent No. DE 31 46 133 is a spiral staircase with two types of steps, each of which has an uneven portion. Discloses a spiral staircase that does not complement each other to increase the surface that can support the foot.
本発明はしたがって、上記欠点を排除することを目的としている。 The present invention is therefore aimed at eliminating the above drawbacks.
本発明は、特許請求の範囲に記載された特徴に基づいて、異なる形、且つ、互いに補完する形を有している２種の段を交互に配置することにより、前記目的を達成している。 The present invention achieves the above object by alternately arranging two stages having different shapes and shapes complementary to each other based on the features described in the claims. .
本発明の主な利点は、基本的に、らせん階段の昇降が著しく円滑になることである。特に、ある段から他の段への移動時に、内足をサポートすることのできる面が増え、使用者に一層の安定性およびバランスを保証していることである。 The main advantage of the present invention is basically that the raising and lowering of the spiral staircase is significantly smoother. In particular, when moving from one level to another level, the number of surfaces that can support the inner foot is increased, which ensures more stability and balance for the user.
さらに段の形により、ライザーと踏み面との比率に相当する値を、外足と内足とで実質的に同じにすることができる。加えて踊り場の形により、段の数を増やし、ライザーを減らし、ライザーと踏み面との比率に相当する値を一直線の傾斜により得られる場合に近づけることができる。 Furthermore, the value corresponding to the ratio between the riser and the tread surface can be made substantially the same between the outer foot and the inner foot due to the shape of the step. In addition, depending on the shape of the landing, the number of steps can be increased, the number of risers can be reduced, and the value corresponding to the ratio between the risers and the treads can be brought closer to that obtained by a straight slope.
結果的に本発明の構造は、段の高さを調整し、如何なる平面図（円や正方形など）や回転方向（時計回り、あるいは反時計回り）も採用し、如何なる物質（木、鉄、アルミニウムなど）や色を用いて生産をするためのシステムにより、どんな高さにも対応するために必要な柔軟性を保証する。 As a result, the structure of the present invention adjusts the height of the step, adopts any plan view (circle, square, etc.) and rotation direction (clockwise or counterclockwise), and any material (wood, iron, aluminum) Etc.) and a system for production using colors, guarantees the flexibility necessary to accommodate any height.
本発明の更なる利点および特徴は、本発明の好ましく、且つ、非限定的実施例として描かれている添付の図面を参照しながら、下記実施形態により明らかとなる。
添付の図面によると、本発明はらせん階段に関する。前記らせん階段は、中心の支持部材（１）と、第１端部（２ａ）で前記支持部材（１）に連結している複数の段（２）とを有している。特に、図２および４に示すように、前記らせん階段は２種類の段（２１、２２）を有していて、第１の段（２１）は実質的に「Ｌ」の形を有していて、第２の段（２２）は実質的に矢の形を有している。前記２種の段は階段（１０）に沿って交互に配置されていて、その詳細は図３に示されている。 According to the accompanying drawings, the present invention relates to a spiral staircase. The spiral staircase has a central support member (1) and a plurality of steps (2) connected to the support member (1) at a first end (2a). In particular, as shown in FIGS. 2 and 4, the spiral staircase has two types of steps (21, 22), and the first step (21) has a substantially “L” shape. Thus, the second stage (22) has a substantially arrow shape. The two types of steps are arranged alternately along the stairs (10), the details of which are shown in FIG.
第１の段（２１）は少なくとも1つの凸部（２１ａ）と1つの凹部（２１ｂ）とを有していて、それらは、第２の段（２２）の少なくとも1つの凸部（２２ａ）と1つの凹部（２２ｂ）とを補完する。凸部（２１ａ、２２ａ）および凹部（２１ｂ、２２ｂ）は、段（２１、２２）の上に踏み場所（２１ｃ、２２ｃ）を形成している。踏み場所（２１ｃ、２２ｃ）は、本発明が提案する利点を達成するのに厳密には必要のない部位（２１ｄ、２２ｄ）とは離れている。このようにすることで、人が階段（１０）を昇降するときに、「Ｌ」型の段（２１）は外足のみをサポートし、一方、矢型の段（２２）は内足のみをサポートする。 The first stage (21) has at least one convex part (21a) and one concave part (21b), which are at least one convex part (22a) of the second stage (22). One recess (22b) is complemented. The convex portions (21a, 22a) and the concave portions (21b, 22b) form stepping places (21c, 22c) on the steps (21, 22). The stepping places (21c, 22c) are separated from the parts (21d, 22d) that are not strictly necessary to achieve the advantages proposed by the present invention. In this way, when a person moves up and down the stairs (10), the “L” -shaped step (21) supports only the outer leg, while the arrow-shaped step (22) supports only the inner foot. to support.
階段（１０）はまた踊り場（５）を有していて、踊り場（５）の端（５ａ）は２種類の段（２１；２２）のうちの1つと同様の形を有している。勿論、端（５ａ）の形によって、階段（１０）を使用する者は誰でも、踊り場（５）の端（５ａ）が矢型の段（２２）のような形であれば外足から踏み出さなければならず、踊り場（５）の端（５ａ）が「Ｌ」型の段（２１）のような形であれば内足から踏み出さなければならない。後者の場合、段（２）の数を増やし、ライザーを減らしても良い。 The staircase (10) also has a landing (5), and the end (5a) of the landing (5) has a shape similar to one of the two types of steps (21; 22). Of course, depending on the shape of the end (5a), anyone who uses the stairs (10) will step out from the outer leg if the end (5a) of the landing (5) is shaped like an arrow-shaped step (22). If the end (5a) of the landing (5) is shaped like an “L” shaped step (21), it must be stepped out from the inner foot. In the latter case, the number of stages (2) may be increased and the risers may be reduced.
全ての概説として、図１はまた、安全のために必要で、段（２）の第２端部（２ｂ）に連結している手すり（３）と、段（２）のライザーを規定するスペーサ部材（４）とを示している。 As an overview of all, FIG. 1 is also necessary for safety and includes a handrail (3) connected to the second end (2b) of the step (2) and a spacer defining the riser of the step (2) The member (4) is shown.
上述の本発明は、発明の概念の範囲から逸脱しない程度に、いくつかの修正や適合を加えても良い。さらに、本発明の全ての部材を技術的に同等の部材と置き換えても良い。 The present invention described above may be subject to some modifications and adaptations without departing from the scope of the inventive concept. Furthermore, all members of the present invention may be replaced with technically equivalent members.
勿論、下記特許請求の範囲内での実際の修正および／または改良は可能である。 Of course, actual modifications and / or improvements within the scope of the following claims are possible.
