Therefore, on the lower surface side of the mounting plate 5, leg portions 8 for raising the radial thickness of the string-shaped body 6 from the pit floor surface are provided. By providing the leg portion 8 on the mounting plate 5, when the string-shaped body 6 is arranged on the lower surface side of the mounting plate 5, the mounting plate 5 is not affected by the string-shaped body 6 and is stably placed on the pit floor. Installed on the surface.
また、紐状体６が貫通穴７ａ～７ｈに配置された状態で、貫通穴７ａと７ｂ、貫通穴７ｃと７ｄ、貫通穴７ｅと７ｆ、貫通穴７ｇと７ｈ、のそれぞれの間で取付板５の上面側に引き出された紐状体６によって屈曲部９ａ～９ｄが形成されている。屈曲部９ａ～９ｄは、紐状体６がコイルバネ４の素線に支持されたとき、アーチ形状１０ａ～１０ｄを形成可能なように配置されている。また、このアーチ形状１０ａ～１０ｄの高さは、コイルバネ４が支持される素線の高さに比例しており、アーチ形状１０ａ～１０ｄの順番に高くなっている。
Further, in a state where the string-shaped body 6 is arranged in the through holes 7a to 7h, a mounting plate is provided between the through holes 7a and 7b, the through holes 7c and 7d, the through holes 7e and 7f, and the through holes 7g and 7h, respectively. The bent portions 9a to 9d are formed by the string-like body 6 pulled out on the upper surface side of the 5. The bent portions 9a to 9d are arranged so that the arch shapes 10a to 10d can be formed when the string-shaped body 6 is supported by the wire of the coil spring 4. Further, the height of the arch shapes 10a to 10d is proportional to the height of the wire supporting the coil spring 4, and the heights of the arch shapes 10a to 10d are increased in this order.
また、紐状体６の長さは、現物合せによって予め調整する。すなわち、始めにコイルバネ４を自由長が垂直方向に向くように取付板５の上面に仮置する。紐状体６を貫通穴７ａ～７ｈに挿した状態で、コイルバネ４の下端部の素線端部を紐状体６の４カ所の屈曲部９ａ～９ｄに順次挿入しながら、コイルバネ４の巻方向と同じ方向にコイルバネ４を回転させる。
In addition, the length of the string-shaped body 6 is adjusted in advance by matching the actual product. That is, first, the coil spring 4 is temporarily placed on the upper surface of the mounting plate 5 so that the free length faces in the vertical direction. With the string-shaped body 6 inserted into the through holes 7a to 7h, the coil spring 4 is wound while the wire ends of the lower end of the coil spring 4 are sequentially inserted into the four bent portions 9a to 9d of the string-shaped body 6. The coil spring 4 is rotated in the same direction as the direction.
４カ所の屈曲部９ａ～９ｄにコイルバネ４の素線が挿入された状態で、コイルバネ４を回転させることにより、屈曲部９ａ～９ｄによってアーチ形状１０ａ～１０ｄが形成された時点で、紐状体６の両端部を互いに近接させて仮留めする。このとき、仮留めした長さは余裕代を含んでいるため、少なくとも仮留めした紐状体６の長さよりも少し短い長さが確保できるように紐状体６の長さを予め調整する。このように長さを調整した紐状体６を貫通穴７ａ～７ｈに順次挿入して、全ての貫通穴７ａ～７ｈに挿入された状態で、両端部を取付板５の下面側で本結びなどの容易に緩むことがないような結び方で接続する。
When the wire of the coil spring 4 is inserted into the four bent portions 9a to 9d and the coil spring 4 is rotated to form the arch shapes 10a to 10d by the bent portions 9a to 9d, the string-like body is formed. Both ends of 6 are brought close to each other and temporarily fastened. At this time, since the length temporarily fastened includes a margin, the length of the string-shaped body 6 is adjusted in advance so that at least a length slightly shorter than the length of the temporarily fastened string-shaped body 6 can be secured. The string-shaped bodies 6 whose lengths have been adjusted in this way are sequentially inserted into the through holes 7a to 7h, and in a state where they are inserted into all the through holes 7a to 7h, both ends are finally tied on the lower surface side of the mounting plate 5. Connect with a knot that does not loosen easily.
次に、上記のように構成された実施の形態１の動作について説明する。始めに、コイルバネ４を自由長が垂直方向に向くように取付板５の上面に仮置きする。紐状体６を貫通穴７ａ～７ｈに順番に通して、紐状体６によって取付板５の上面側で各一対の貫通穴７ａ～７ｈ毎に４カ所の屈曲部９ａ～９ｄが形成されるように取付板５に配置する。次に、コイルバネ４の下端部の素線端部を紐状体６の４カ所の屈曲部９ａ～９ｄに順次挿入しながら、コイルバネ４自体を取付板５上でコイルバネ４の巻方向と同じ方向に回転させる。コイルバネ４を回転させると、屈曲部９ａ～９ｄがコイルバネ４の素線に順次支持されながら、次第に上方へ引き上げられていく。
Next, the operation of the first embodiment configured as described above will be described. First, the coil spring 4 is temporarily placed on the upper surface of the mounting plate 5 so that the free length faces in the vertical direction. The string-shaped body 6 is passed through the through holes 7a to 7h in order, and the string-shaped body 6 forms four bent portions 9a to 9d for each pair of through holes 7a to 7h on the upper surface side of the mounting plate 5. It is arranged on the mounting plate 5 so as to. Next, while sequentially inserting the wire ends of the lower end of the coil spring 4 into the four bent portions 9a to 9d of the string-like body 6, the coil spring 4 itself is inserted on the mounting plate 5 in the same direction as the winding direction of the coil spring 4. Rotate to. When the coil spring 4 is rotated, the bent portions 9a to 9d are gradually pulled upward while being sequentially supported by the strands of the coil spring 4.
ここで、コイルバネ４を回転させると、屈曲部９ａ～９ｄがコイルバネ４の素線に支持されながら上方に引き上げられて、アーチ形状１０ａ～１０ｄが形成される。さらにコイルバネ４を回転させると、紐状体６は両端が接続されているため、アーチ形状１０ａ～１０ｄの高さが所定の高さに到達した時点で、紐状体６は長さの限界に達する。ここで、紐状体６の張り具合を確認する。紐状体６に余裕がある場合、さらにコイルバネ４をゆっくりと同じ方向に回転させる。コイルバネ４を回転させて、紐状体６の張り具合を確認したとき、紐状体６に余裕が無くなり、張り詰めた状態になった時点で、コイルバネ４の回転を止める。
Here, when the coil spring 4 is rotated, the bent portions 9a to 9d are pulled upward while being supported by the strands of the coil spring 4, and arch shapes 10a to 10d are formed. Further, when the coil spring 4 is rotated, both ends of the string-shaped body 6 are connected to each other. Therefore, when the heights of the arch shapes 10a to 10d reach a predetermined height, the string-shaped body 6 reaches the limit of length. Reach. Here, the tension of the string-shaped body 6 is confirmed. When the string-shaped body 6 has a margin, the coil spring 4 is further slowly rotated in the same direction. When the coil spring 4 is rotated and the tension of the string-like body 6 is confirmed, the rotation of the coil spring 4 is stopped when the string-like body 6 has no margin and becomes tense.
ここで、コイルバネ４を左右に動かしてみたとき、ぐらつかず、容易に動かない状態であれば、コイルバネ４の固定作業は完了する。また、コイルバネ４を前後左右に動かしてみたとき、コイルバネ４がぐらついたり、固定されていない場合には、さらにコイルバネ４を同じ要領で回転させて、取付板５上で容易に動かない状態になった時点で、コイルバネ４の固定作業は完了する。
Here, when the coil spring 4 is moved left and right, if it does not wobble and does not move easily, the fixing work of the coil spring 4 is completed. Further, when the coil spring 4 is moved back and forth and left and right, if the coil spring 4 is not fixed or wobbles, the coil spring 4 is further rotated in the same manner so that it cannot be easily moved on the mounting plate 5. At that point, the fixing work of the coil spring 4 is completed.

6 to 7 show the elevator spring shock absorber according to the second embodiment of the present invention, FIG. 6 is a perspective view showing a main part of the elevator spring shock absorber of FIG. 1, and FIG. 7 is FIG. It is a top view which shows the main part of the spring shock absorber of an elevator. In the spring shock absorber of the elevator according to the second embodiment of the present invention, in addition to the pair of through
図において、取付板１１には、一対の貫通穴７ａ～７ｈに加えて、紐状体６の一端と他端とが取付板１１の下面側から挿入されて、上面側に引き出される一対の貫通穴１２ａ、１２ｂが形成されている。貫通穴１２ａ、１２ｂの形状は、貫通穴７ａ～７ｈと同等であり、紐状体６が挿入可能なサイズである。
In the figure, in addition to the pair of through holes 7a to 7h, one end and the other end of the string-shaped body 6 are inserted into the mounting plate 11 from the lower surface side of the mounting plate 11 and pulled out to the upper surface side. Holes 12a and 12b are formed. The shapes of the through holes 12a and 12b are the same as those of the through holes 7a to 7h, and the size is such that the string-shaped body 6 can be inserted.
次に、上記のように構成された実施の形態２の動作について説明する。紐状体６の長さは、現物合せによって調整する。すなわち、始めにコイルバネ４を自由長が垂直方向に向くように取付板１１の上面に仮置きして、紐状体６を貫通穴７ａ～７ｈに挿入する。次にコイルバネ４の下端部の素線端部を紐状体６の４カ所の屈曲部９ａ～９ｄに順次挿入しながら、コイルバネ４の巻方向と同じ方向にコイルバネ４を回転させる。コイルバネ４の素線が挿入された４カ所の屈曲部９ａ～９ｄによってアーチ形状１０ａ～１０ｄが形成された時点で、紐状体６の両端部を互いに近接させて仮留めする。このとき、仮留めした長さは余裕分を含んでいるため、少なくとも仮留めした紐状体６の長さよりも少し短い長さが確保できるように紐状体６の長さを予め調整する。
Next, the operation of the second embodiment configured as described above will be described. The length of the string-shaped body 6 is adjusted according to the actual product. That is, first, the coil spring 4 is temporarily placed on the upper surface of the mounting plate 11 so that the free length faces in the vertical direction, and the string-shaped body 6 is inserted into the through holes 7a to 7h. Next, the coil spring 4 is rotated in the same direction as the winding direction of the coil spring 4 while sequentially inserting the wire ends of the lower end of the coil spring 4 into the four bent portions 9a to 9d of the string-shaped body 6. When the arch shapes 10a to 10d are formed by the four bent portions 9a to 9d into which the wires of the coil spring 4 are inserted, both ends of the string-shaped body 6 are temporarily fastened close to each other. At this time, since the length temporarily fastened includes a margin, the length of the string-shaped body 6 is adjusted in advance so that at least a length slightly shorter than the length of the temporarily fastened string-shaped body 6 can be secured.
このように長さを調整した紐状体６の一端を取付板１１の下面側から貫通穴１２ａに挿入し、紐状体６の他端を取付板１１の下面側から貫通穴１２ｂに挿入する。次に、取付板１１の上面側に引き出した紐状体６の両端部を取付板５の上面側で接続する。
One end of the string-shaped body 6 whose length is adjusted in this way is inserted into the through hole 12a from the lower surface side of the mounting plate 11, and the other end of the string-shaped body 6 is inserted into the through hole 12b from the lower surface side of the mounting plate 11. .. Next, both ends of the string-shaped body 6 pulled out to the upper surface side of the mounting plate 11 are connected on the upper surface side of the mounting plate 5.
上記のように実施の形態２によれば、取付板１１には一対の貫通穴７ａ～７ｈに加えて、紐状体６の一端と他端とが取付板１１の下面側から挿入されて、上面側に引き出される一対の貫通穴１２ａ、１２ｂが形成されていることにより、コイルバネ４の組成は従来と同じものでありながら、熱の影響を受けることなくコイルバネ４を取付板１１に容易に固定できるエレベータのバネ緩衝器を提供することができる。
As described above, according to the second embodiment, in addition to the pair of through holes 7a to 7h, one end and the other end of the string-shaped body 6 are inserted into the mounting plate 11 from the lower surface side of the mounting plate 11. By forming a pair of through holes 12a and 12b drawn out on the upper surface side, the composition of the coil spring 4 is the same as the conventional one, but the coil spring 4 is easily fixed to the mounting plate 11 without being affected by heat. Elevator spring shock absorbers can be provided.
また、実施例１の場合は、取付板５にコイルバネ４が固定された後、紐状体６が伸びることにより、取付板５におけるコイルバネ４の固定が緩くなった場合、紐状体６の両端部は取付板５の下面側で固定されているため、紐状体６の長さを調整するには、取付板５をいったん昇降路のピット床から取り外す手間が発生する。実施例２では、取付板１１の上面側から紐状体６の長さを調整することができるので、取付板５をいったん昇降路のピット床から取り外すことなく最小限の手間で紐状体６の長さを調整することができる。
Further, in the case of the first embodiment, when the coil spring 4 is fixed to the mounting plate 5 and then the string-shaped body 6 is stretched to loosen the fixing of the coil spring 4 on the mounting plate 5, both ends of the string-shaped body 6 are loosened. Since the portion is fixed on the lower surface side of the mounting plate 5, it takes time to remove the mounting plate 5 from the pit floor of the hoistway in order to adjust the length of the string-shaped body 6. In the second embodiment, since the length of the string-shaped body 6 can be adjusted from the upper surface side of the mounting plate 11, the string-shaped body 6 can be adjusted with a minimum of effort without removing the mounting plate 5 from the pit floor of the hoistway. You can adjust the length of.
なお、実施の形態１では、一対の貫通穴７ａ～７ｈは４ヵ所（１カ所／２つ）に計８つ設けているが、必ずしも４か所または８つを設ける必要はない。すなわち、取付板５上に紐状体６を配置して、コイルバネ４を回転させて固定したとき、緩みが無く固定できればよく、貫通穴は４ヵ所より少なくまたは多く形成しても同様の作用・効果を奏することは言うまでもない。
In the first embodiment, a total of eight pairs of through holes 7a to 7h are provided at four locations (one location / two locations), but it is not always necessary to provide four or eight locations. That is, when the string-shaped body 6 is arranged on the mounting plate 5 and the coil spring 4 is rotated and fixed, it is sufficient that the coil spring 4 can be fixed without loosening, and the same effect can be obtained even if less or more through holes are formed. It goes without saying that it is effective.
また、実施の形態１～２では、貫通穴７ａ～７ｈは鉛直方向上部から見たとき、コイルバネ４の素線の長手方向に対して直角に交差する線上かつ素線の両側近傍に一対で形成しているが、必ずしも直角でなくても良い。すなわち、紐状体６がコイルバネ４の素線に支持されるように交差していれば良い。
Further, in the first and second embodiments, the through holes 7a to 7h are formed in pairs on the line intersecting at right angles to the longitudinal direction of the wire of the coil spring 4 and in the vicinity of both sides of the wire when viewed from above in the vertical direction. However, it does not have to be a right angle. That is, the string-shaped bodies 6 may intersect so as to be supported by the strands of the coil spring 4.
