Description

丸型ロープやフラットベルトなどの長尺の荷重支持部材には種々の用途が存在する。こうした用途の一つはエレベータシステムの荷重を懸垂することである。   There are various uses for a long load support member such as a round rope or a flat belt. One such application is to suspend loads in elevator systems.

荷重支持部材はエレベータシステムの駆動すなわち推進に使用される。丸形のスチールロープは長年に亘る業界標準である。最近になり、ジャケット内に実質的に保持された複数の引張部材コードを含むフラットベルトがエレベータシステムで使用されている。こうしたエレベータシステムのベルトに関連する多くの利点があるが、提示される多くの課題も存在する。   The load bearing member is used to drive or propel the elevator system. Round steel rope has been an industry standard for many years. More recently, flat belts including a plurality of tension member cords substantially retained within a jacket have been used in elevator systems. While there are many advantages associated with such elevator system belts, there are also many challenges presented.

国際公開第２００５／０９４２５５号International Publication No. 2005/094255

例えば、一部のエレベータベルトに提示される一つの課題は、ベルトの移動延いてはエレベータかごの移動を生じさせるベルトと駆動綱車との間に所望の割合の牽引力を実現することである。エレベータベルトの表面に特定の牽引特性を実現するための異なるアプローチが提案されている。一つのアプローチが特許文献１に示される。この文献では、ジャケットが、所望の摩擦特性を提供するための粗面を含む。   For example, one challenge presented to some elevator belts is to achieve the desired percentage of traction between the belt and the drive sheave that cause the movement of the belt and thus the movement of the elevator car. Different approaches have been proposed to achieve specific traction characteristics on the surface of the elevator belt. One approach is shown in US Pat. In this document, the jacket includes a rough surface to provide the desired friction properties.

その他の課題は、ジャケットをベルトに適用するために用いられる技術に関連する。一部のこうした技術により、エレベータ動作中のノイズの原因になると推定される特徴部が生じる。ジャケット層の追加により、コストおよび製造の複雑さが増大する。   Another challenge relates to the technique used to apply the jacket to the belt. Some such techniques result in features that are presumed to cause noise during elevator operation. The addition of a jacket layer increases cost and manufacturing complexity.

一例の長尺のエレベータ荷重支持部材が、その長さに沿って延在する複数の引張要素を含む。引張要素を横切る複数の織物繊維が引張要素とともに織り込まれて、それらの織物繊維が、複数の引張要素の互いに関する所望の間隔および配列を維持する。織物繊維は、引張要素を少なくとも部分的に被覆する。その織物繊維は露出して、荷重支持部材の外側の牽引面を構築する。   An example elongate elevator load bearing member includes a plurality of tension elements extending along its length. A plurality of textile fibers across the tensioning element are woven together with the tensioning elements so that the textile fibers maintain a desired spacing and arrangement of the plurality of tensioning elements with respect to one another. The textile fibers at least partially cover the tensile element. The fabric fibers are exposed to build the outer traction surface of the load bearing member.

A plurality of textile fibers are woven together with the tensile elements, thereby maintaining the desired spacing and arrangement of the plurality of tensile elements with respect to each other. Textile fibers at least partially cover the tensile element. The fabric fibers are exposed to build the outer traction surface of the load bearing member.

開示の実施例の様々な特徴および利点が以下の詳細な説明から当業者にとって明らかとなるであろう。詳細な説明に添付の図面を以下のように簡単に説明する。   Various features and advantages of the disclosed embodiments will become apparent to those skilled in the art from the following detailed description. The drawings that accompany the detailed description can be briefly described as follows.

一例のエレベータシステムの選択された部分を概略的に示す図。FIG. 2 schematically illustrates selected portions of an example elevator system. 引張要素とともに編み組まれた織物繊維を有する一例の荷重支持部材を概略的に示す図。1 schematically shows an example load bearing member having woven fibers braided with tensile elements. FIG. ２つ以上の方向に織物繊維を含む一例の織物パターンを概略的に示す図。The figure which shows schematically the example textile pattern containing a textile fiber in two or more directions. 織物ベルトに亘って分散された引張要素を含むその他の例を概略的に示す図。FIG. 6 schematically illustrates another example including tensioning elements distributed across a woven belt.

図１は一例の牽引エレベータシステム２０の選択された部分を概略的に示す。図示の例は説明目的のためにすぎない。本発明の理解に不要なエレベータシステム２０の特徴部（例えば、ガイドレール、安全装置など）は図示も説明もしていない。本発明が種々のエレベータシステム構成に用いられ、この図に示される特定の例だけに用いられるのではないことが当業者にとって理解できるであろう。この例は、一つ以上の長尺のエレベータ荷重支持部材３０により１：１のローピング配置でカウンタウェイト２４と一体となったエレベータかご２２を含む。２：１またはそれ以上のその他のローピング配置が可能である。エレベータかご２２およびカウンタウェイト２４の重量が長尺のエレベータ荷重支持部材３０によって懸垂される。   FIG. 1 schematically illustrates selected portions of an example traction elevator system 20. The example shown is for illustrative purposes only. Features (e.g., guide rails, safety devices, etc.) of the elevator system 20 that are not necessary for an understanding of the present invention are not shown or described. It will be appreciated by those skilled in the art that the present invention may be used in various elevator system configurations and not only in the specific example shown in this figure. This example includes an elevator car 22 that is integral with the counterweight 24 in a 1: 1 roping arrangement with one or more elongated elevator load bearing members 30. Other roping arrangements of 2: 1 or more are possible. The weights of the elevator car 22 and the counterweight 24 are suspended by the long elevator load support member 30.

駆動綱車３１Ａにより長尺のエレベータ荷重支持部材３０を所望のように移動させて、昇降路内でのエレベータかご２２の所望の移動および配置を実現する。図示の例のエレベータシステム２０は、図１に示すように長尺のエレベータ荷重支持部材３０と係合するそらせ車３１Ｂを含む。その他の例はまた、かご２２上、カウンタウェイト２４上、またはその両方にある、長尺のエレベータ荷重支持部材３０と係合する一つ以上の遊び車またはダイバータプーリを含む（例えば、オーバスラングまたはアンダースラング式のローピング配置を提供するように）。   The long elevator load support member 30 is moved as desired by the driving sheave 31A to realize the desired movement and arrangement of the elevator car 22 in the hoistway. The elevator system 20 in the illustrated example includes a baffle 31B that engages with a long elevator load support member 30 as shown in FIG. Other examples also include one or more play wheels or diverter pulleys that engage the elongated elevator load bearing member 30 on the car 22, on the counterweight 24, or both (e.g., overslang or To provide an underslang roping arrangement).

図２は一例の長尺のエレベータ荷重支持部材３０を示す。この例は複数の引張要素３２を含む。図から認識できるように、引張要素３２は概ね互いに平行に配置されるとともに、この長尺のエレベータ荷重支持部材３０の長さ寸法を画定する長手方向に延在する。複数の織物繊維３４が引張要素３２とともに織り込まれる。この例では、織物繊維３４および引張要素３２が互いに織物内に織り込まれて、この織物が引張要素３２を互いに関して所望の方向に維持する。換言すれば、織物繊維３４は実質的に引張要素３２を所定の位置に保持する。文言「実質的に保持する」とは、使用時（例えば、長尺のエレベータ荷重支持部材３０が、潜在的に付加的な安全係数を有するエレベータシステム２０の使用時に発生する荷重に曝されたとき）に引張要素３２が織物から引き抜かれず、織物繊維３４に対して実質的に静止した状態となるように、織物繊維３４が引張要素３２と十分に係合することを意味する。この例の織物繊維３４は引張部材３２の長さすなわち長手方向に対して横方向の長さを有する。   FIG. 2 shows an example of a long elevator load support member 30. This example includes a plurality of tension elements 32. As can be appreciated from the figure, the tension elements 32 are disposed generally parallel to one another and extend in a longitudinal direction that defines the length dimension of the elongated elevator load bearing member 30. A plurality of textile fibers 34 are woven together with the tensile elements 32. In this example, fabric fibers 34 and tension elements 32 are woven together into the fabric, which maintains the tension elements 32 in the desired orientation with respect to each other. In other words, the fabric fiber 34 substantially holds the tension element 32 in place. The phrase “substantially hold” means in use (eg, when the long elevator load bearing member 30 is exposed to a load generated during use of the elevator system 20 with a potentially additional safety factor). ) Means that the fabric fibers 34 are sufficiently engaged with the tension elements 32 so that the tension elements 32 are not pulled out of the fabric and remain substantially stationary relative to the fabric fibers 34. The fabric fiber 34 in this example has a length in a direction transverse to the length of the tension member 32, that is, the longitudinal direction.

この例の荷重支持部材３０は、その少なくとも片側に外側の牽引面３６を含む。牽引面３６は露出した織物繊維３４によって画定される。大半の実施例では、「露出した」織物繊維３４が全長に沿って露出しているのではない。各織物繊維３４の一部が別の織物繊維３４または引張要素３２の下にあるように織物繊維３４が荷重支持部材３０の織物に織り込まれる。   The load support member 30 of this example includes an outer pulling surface 36 on at least one side thereof. The traction surface 36 is defined by exposed fabric fibers 34. In most embodiments, “exposed” fabric fibers 34 are not exposed along their entire length. The fabric fibers 34 are woven into the fabric of the load bearing member 30 such that a portion of each fabric fiber 34 is below another fabric fiber 34 or tension element 32.

図示の例では、全ての織物繊維３４が外側の牽引面３６に露出している。一部の例では、織物の複数の層または織物繊維３４の配置が、織物繊維３４の少なくとも一部をその他の織物繊維３４によって完全に覆われた状態にする。このような例では、一部の織物繊維のみが露出して外側の牽引面を画定する。   In the illustrated example, all the textile fibers 34 are exposed on the outer pulling surface 36. In some examples, the arrangement of multiple layers of fabric or fabric fibers 34 causes at least a portion of the fabric fibers 34 to be completely covered by other fabric fibers 34. In such an example, only some of the fabric fibers are exposed to define the outer traction surface.

引張要素３２はエレベータ荷重支持部材３０の主な荷重支持構造である。一部の例では、織物繊維３４はエレベータかご２２またはカウンタウェイト２４の重量を支持しない。それでもなお、織物繊維３４は荷重経路の一部を形成する。織物繊維３４は牽引面３６で露出するため、織物繊維３４は、駆動綱車３１とエレベータ荷重支持部材３０との間の牽引力を引張要素３２に直接伝達する。   The tension element 32 is the main load support structure of the elevator load support member 30. In some examples, the fabric fibers 34 do not support the weight of the elevator car 22 or counterweight 24. Nevertheless, the fabric fibers 34 form part of the load path. Since the fabric fibers 34 are exposed at the traction surface 36, the fabric fibers 34 directly transmit the traction force between the drive sheave 31 and the elevator load support member 30 to the tension element 32.

一部の例の織物繊維３４は、引張要素３２の、牽引面３６が係合するあらゆるコンポーネントに対する接触を防止する。例えば、荷重支持部材３０が駆動綱車３１の周りに少なくとも部分的に巻きつくため、引張要素３２は駆動綱車３１の表面に接触しない。織物繊維３４の寸法、織物繊維３４の材料、織物繊維３４のパターン、またはそれらの組合せが引張要素３２と牽引面３６との間に所望の間隔を保証するように選択されて、引張要素３２が駆動綱車３１などのコンポーネントと直接係合するのを防ぐ。織物繊維３４は一部の例では、牽引面３６と同じ方向に面した引張要素３２の５０％を越える表面領域を保護する。   Some example fabric fibers 34 prevent the tensioning element 32 from contacting any component with which the traction surface 36 engages. For example, the tensioning element 32 does not contact the surface of the drive sheave 31 because the load support member 30 wraps at least partially around the drive sheave 31. The dimensions of the woven fibers 34, the material of the woven fibers 34, the pattern of the woven fibers 34, or a combination thereof are selected to ensure the desired spacing between the tension element 32 and the pulling surface 36 so that the tension element 32 Prevents direct engagement with components such as the drive sheave 31. The woven fibers 34 in some instances protect over 50% of the surface area of the tensile element 32 facing in the same direction as the traction surface 36.

一例では引張要素３２は第１の材料を備え、織物繊維３４は第２の異なる材料を備える。図示の例では、織物繊維３４は引張要素３２と比較して、はるかに小さい厚さすなわち断面寸法を有する。一例では、引張要素３２は引き抜き鋼（ｄｒａｗｎ ｓｔｅｅｌ）などの金属であり、織物繊維３４は例えばポリマなどの非金属材料を備える。図２に示す例の引張要素３２は、それぞれ巻き込まれたワイヤを備えた金属コードを備える。   In one example, the tension element 32 comprises a first material and the woven fiber 34 comprises a second different material. In the illustrated example, the woven fiber 34 has a much smaller thickness or cross-sectional dimension compared to the tensile element 32. In one example, the tensile element 32 is a metal such as drawn steel, and the woven fiber 34 comprises a non-metallic material such as a polymer. The tensile element 32 of the example shown in FIG. 2 comprises a metal cord with a wound wire each.

この例の製織処理の結果、織物繊維３４がその各々の長さに沿って様々な位置に配置される一方で、各引張要素３２はその長さに沿って概ね平面となる向きに維持される。織物繊維３４は引張要素３２に比べて軽量であり、この織物繊維３４は製織処理時に引張要素の外面の周りに適合するように操作される。織物繊維３４の各々は引張要素のうちの一つの（図面に基づく）頂部、隣接する引張要素３２の底部、およびその隣の引張要素の頂部に亘って部分的に巻き付けられる。一部の例では、引張要素３２は製織処理中に張力がかけられた状態に維持され、それにより織物繊維３４が織り込まれるその一部の長さに沿って引張要素３２を直線状に保つ。   As a result of the weaving process of this example, the fabric fibers 34 are positioned at various locations along their respective lengths, while each tensile element 32 is maintained in a generally planar orientation along its length. . The fabric fibers 34 are lighter than the tension elements 32, and the fabric fibers 34 are manipulated to fit around the outer surface of the tension elements during the weaving process. Each of the fabric fibers 34 is partially wrapped around the top of one of the tensile elements (based on the drawing), the bottom of the adjacent tensile element 32, and the top of the adjacent tensile element. In some examples, the tension element 32 is maintained in tension during the weaving process, thereby keeping the tension element 32 straight along the length of the portion of the fabric fiber 34 that is woven.

図示の例では、全ての引張要素３２が互いに概ね平行かつ概ね同一平面上の配列に揃えられる。この織物繊維３４は、エレベータ装置のシーブの周りで荷重支持部材３０が屈曲するのを可能にしながらその所望の配列を維持する。織物繊維３４は、荷重支持部材３０上にあらゆる外部コーティングやジャケットを必要とせずに、引張要素３２の所望の相対的な配向を維持する。   In the illustrated example, all tensioning elements 32 are aligned in a generally parallel and generally coplanar arrangement. The fabric fibers 34 maintain their desired alignment while allowing the load bearing member 30 to bend around the sheaves of the elevator apparatus. The woven fibers 34 maintain the desired relative orientation of the tensioning elements 32 without requiring any external coating or jacket on the load bearing member 30.

一部の例では、織物繊維３４は牽引面３６を構築するために有効なエラストマ材料を含むまたは備える。一例は、所望の材料の織物繊維３４を構築し、次いでその繊維をエラストマ材料で被覆するまたはエラストマ材料に含浸させることを含む。別の例は、複数のフィラメントから織物繊維３４の各々を形成し、その織物繊維３４の各々の内部に選択されたエラストマ材料で作られたフィラメントを含有させることを含む。一例のエラストマ材料はウレタンを備える。一例では熱可塑性ポリウレタンが用いられる。   In some examples, the fabric fibers 34 include or comprise an elastomeric material that is effective for constructing the traction surface 36. An example includes constructing a woven fiber 34 of the desired material and then coating or impregnating the fiber with an elastomer material. Another example includes forming each of the fabric fibers 34 from a plurality of filaments, and including within each of the fabric fibers 34 a filament made of a selected elastomeric material. One example elastomeric material comprises urethane. In one example, thermoplastic polyurethane is used.

一部の例では、織物繊維３４は、周知ののり剤で処理された撚り糸を備える。一部の例のサイジングにより、引張要素３２と織物繊維とを一緒に織り込む能力が強化される。一部の例のサイジングにより、エレベータ装置の使用時の織物繊維のフレッチングまたは摩損を最小限に抑えるなど、織物繊維３４の摩耗特性が強化される。一部の例のサイジングにより、牽引面３６に所望の牽引特性が提供される。   In some examples, the woven fiber 34 comprises a twisted yarn that has been treated with a well-known glue. Some example sizing enhances the ability to weave the tension element 32 and the fabric fibers together. Some example sizing enhances the wear characteristics of the fabric fibers 34, such as minimizing fretting or abrasion of the fabric fibers when using the elevator system. Some example sizing provides the traction surface 36 with the desired traction characteristics.

織物繊維３４と引張要素３２とを互いに織り込むように種々の異なる織目が用いられうる。図２は織物繊維３４の一つのこうした例のパターンを示す。この例では、外側の牽引面３６に露出する織物繊維３４は概ね互いに平行に揃えられるとともに引張要素３２の長手方向に対して概ね垂直に揃えられる。   A variety of different textures can be used to weave the woven fibers 34 and the tensile elements 32 together. FIG. 2 shows one such example pattern of fabric fibers 34. In this example, the fabric fibers 34 exposed on the outer pulling surface 36 are aligned generally parallel to each other and aligned generally perpendicular to the longitudinal direction of the tension element 32.

図３は織物繊維３４の互いに関しての相対的な配列を示すように部分的に拡張された別の例の織目を概略的に示す（完成形のアセンブリは図２に示すものと同様に織物繊維３４と引張要素３２とが互いにずっと近い）。この例では、一部の織物繊維３４ａは引張要素３２の長手方向すなわちその長さに対して概ね垂直に配置される。その他の織物繊維３４ｂは、引張要素３２に対して概ね平行かつ織物繊維３４ａに対して概ね垂直に配置される。図２と図３とを比較することによって理解されるように、図３の例の織目は、織物繊維３４ｂが牽引面３６に露出する位置に含まれる場合に、牽引面３６に僅かに異なる特性を有する。別の例では、織物繊維３４ｂは引張要素３２の間の隙間のみに維持されるとともに、牽引面３６の外形すなわち織地に影響を及ぼさないように露出しない。   FIG. 3 schematically illustrates another example weave partially expanded to show a relative arrangement of the fabric fibers 34 with respect to each other (the finished assembly is a fabric similar to that shown in FIG. The fibers 34 and the tension elements 32 are much closer together). In this example, some of the fabric fibers 34a are arranged generally perpendicular to the longitudinal direction of the tension element 32, ie its length. The other fabric fibers 34b are arranged generally parallel to the tension element 32 and generally perpendicular to the fabric fibers 34a. As can be seen by comparing FIG. 2 and FIG. 3, the texture of the example of FIG. Has characteristics. In another example, the fabric fibers 34b are maintained only in the gaps between the tension elements 32 and are not exposed so as not to affect the contour of the traction surface 36, ie the fabric.

図３の例の一つの特徴は、引張要素３２の各々がコーティング４０を含むことである。一例では、コーティング４０は引張要素３２の材料の腐食を防ぐための保護コーティングである。別の例では、コーティング４０は、織物繊維３４と引張要素３２の外表面との適切な位置決めすなわちそれらの間の接合を容易にする接着剤を備える。さらに別の例のコーティング４０はエレベータ装置の使用時の引張要素３２の材料を保護するのに有効なエラストマを備える。エラストマコーティング４０は、例えば織物の構築後にそのコーティング４０が加熱される場合に、織物繊維３４を、引張要素３２に対して所定の位置に適切に位置決めすなわち接合するのに役立つ。   One feature of the example of FIG. 3 is that each of the tension elements 32 includes a coating 40. In one example, the coating 40 is a protective coating to prevent corrosion of the material of the tension element 32. In another example, the coating 40 comprises an adhesive that facilitates proper positioning of the fabric fibers 34 and the outer surface of the tensile element 32, ie, bonding between them. Yet another example coating 40 comprises an elastomer that is effective to protect the material of the tensile element 32 when the elevator apparatus is in use. The elastomeric coating 40 serves to properly position or bond the fabric fibers 34 in place with respect to the tensioning element 32, for example when the coating 40 is heated after the construction of the fabric.

図２の例では、各引張要素３２は、単一のコードに撚り合わされたストランド３２Ａを形成する複数のワイヤを備える。その例では、各引張要素３２は、例えば個々の複数の荷重支持ストランド３２Ａすなわち複数のワイヤを備える。図４に示す例では、引張要素３２は織物全体に亘って分散される。この例の引張要素３２は、図２の例に含まれる引張要素などの、撚り合わされたコート内の個々のワイヤまたはストランドと同様の寸法および特性を有する。図４のような例の引張要素３２はより寸法の大きいものでもよい。   In the example of FIG. 2, each tensile element 32 comprises a plurality of wires forming a strand 32A twisted into a single cord. In that example, each tension element 32 comprises, for example, an individual plurality of load bearing strands 32A, ie, a plurality of wires. In the example shown in FIG. 4, the tension elements 32 are distributed throughout the fabric. The tensile elements 32 in this example have similar dimensions and properties as the individual wires or strands in the twisted coat, such as the tensile elements included in the example of FIG. The tensile element 32 in the example as shown in FIG. 4 may have a larger dimension.

図４に示される一例の構成は、引張要素３２として離散した金属ワイヤを含む。こうした一例では、金属ワイヤは織物繊維３４の外径とほぼ等しい外径を有する。別の例では、織物繊維３４は、引張要素３２の織物繊維と比べてより小さい直径を有する。   The example configuration shown in FIG. 4 includes discrete metal wires as tensioning elements 32. In one such example, the metal wire has an outer diameter that is approximately equal to the outer diameter of the woven fiber 34. In another example, the woven fiber 34 has a smaller diameter compared to the woven fiber of the tensile element 32.

開示の例により、エレベータ荷重支持部材の基礎としての織物が提供される。それらにより、二次的な材料すなわちジャケット材料を適用する必要なく、複数の引張要素を有するエレベータ荷重支持部材を実現する能力が提供される。二次的なコーティングすなわちジャケットの必要性を排除することにより、一部の製造工程の経済性が高められ、エレベータ装置に使用される際に課題または障害の種として認識されるようになってきたジャケットの特徴が排除される。   The disclosed example provides a fabric as a basis for an elevator load bearing member. They provide the ability to realize an elevator load bearing member having a plurality of tension elements without having to apply a secondary or jacket material. By eliminating the need for secondary coatings or jackets, the economics of some manufacturing processes have been increased and have become recognized as a source of challenges or obstacles when used in elevator equipment. The jacket feature is eliminated.

開示の例の特徴の一つは、引張要素３２を互いに関して所望の位置に維持するためにジャケットを用いる代わりに織物を用いることにより、ウレタンジャケットに存在する粘弾性の性質に比べて、より優れたダンピング性がもたらされることである。ジャケットの代わりに織物を用いることでより優れたダンピング性を提供することにより、エレベータ装置の運転時のノイズレベルを低減することができる。   One feature of the disclosed example is superior to the viscoelastic nature present in urethane jackets by using a fabric instead of using a jacket to maintain the tension elements 32 in a desired position relative to each other. This is to provide a damping property. By using a woven fabric instead of the jacket, it is possible to reduce the noise level during operation of the elevator apparatus by providing better damping properties.

Various changes and modifications to the disclosed embodiments will become apparent to those skilled in the art without departing from the spirit of the invention. The scope of legal protection given to this invention can only be determined by studying the appended claims.
