FIG. 2 is a diagram of an elevator vibration isolator according to the first embodiment.
　図２に示されるように、実施の形態１における防振装置は、隅部防振具１３と中央防振具１４の２種類の防振具を備える。 As shown in FIG. 2, the vibration isolator according to the first embodiment includes two types of vibration isolators, a corner vibration isolator 13 and a central vibration isolator 14.
　例えば、複数の隅部防振具１３の各々は、振動を吸収する材料からなる。例えば、複数の隅部防振具１３の各々は、弾性体からなる。例えば、複数の隅部防振具１３の各々は、防振ゴムである。複数の隅部防振具１３の各々は、支持枠１２に取り付けられる。複数の隅部防振具１３の各々は、図示されないかご６の床の四隅の下方にそれぞれ設置される。例えば、複数の隅部防振具１３の各々は、支持枠１２の両端側に取り付けられる。複数の隅部防振具１３の各々は、締結具１５により支持枠１２に取り付けられる。 For example, each of the plurality of corner vibration isolators 13 is made of a material that absorbs vibration.

For example, when the weight M of the car 6 (not shown) acts from above, the position of the upper surface of the central vibration isolator 14 becomes the same height as the position of the upper surface of the corner vibration isolator 13 in the natural state. For example, when the weight M of the car 6 (not shown) acts from above, the height of the central vibration isolator 14 becomes equal to the height of the corner vibration isolator 13 in the natural state. For example, the central vibration isolator 14 is attached near the center of the support frame 12. For example, the central vibration isolator 14 is installed below the center of the side of the floor of the car 6 (not shown). The central vibration isolator 14 is attached so that the mounting height of the bottom surface is the same as the mounting height of the bottom surfaces of the plurality of corner vibration isolators 13. The central vibration isolator 14 is attached to the support frame 12 by the fastener 15.

　次に、図３を用いて、防振装置の設置方法について説明する。
　図３は実施の形態１におけるエレベーターの防振装置の設置方法を説明するための図である。 Next, a method of installing the anti-vibration device will be described with reference to FIG.
FIG. 3 is a diagram for explaining a method of installing an elevator vibration isolator according to the first embodiment.
　図３に示されるように、かご床枠１６は、支持枠１２に上方から隣接する。かご床枠１６は、かご６の下部を構成する。かご床枠１６は、かご床１７に下方から隣接する。かご床枠１６は、かご６を下方から支持する。かご床１７は、エレベーターの乗客が乗り込む床面である。 As shown in FIG. 3, the car floor frame 16 is adjacent to the support frame 12 from above. The car floor frame 16 constitutes the lower part of the car 6. The car floor frame 16 is adjacent to the car floor 17 from below. The car floor frame 16 supports the car 6 from below. The car floor 17 is a floor surface on which passengers of the elevator board.
　複数の隅部防振具１３の各々は、かご床枠１６に下方から隣接する。中央防振具１４は、かご床枠１６に下方から隣接する。かご６の重量Ｍは、中央防振具１４に鉛直方向上方から作用する。かご６の重量Ｍは、かご室の重量とかご床枠１６の和である。かご６の重量Ｍは、中央防振具１４と支持枠１２とを介して下枠１１に伝えられる。中央防振具１４の高さは、かご６の重量Ｍが鉛直方向上方から作用すると、隅部防振具１３の高さと同等になる。 Each of the plurality of corner vibration isolators 13 is adjacent to the car floor frame 16 from below. The central vibration isolator 14 is adjacent to the car floor frame 16 from below. The weight M of the car 6 acts on the central vibration isolator 14 from above in the vertical direction. The weight M of the car 6 is the sum of the weight of the car room and the car floor frame 16. The weight M of the car 6 is transmitted to the lower frame 11 via the central vibration isolator 14 and the support frame 12. The height of the central vibration isolator 14 becomes equal to the height of the corner vibration isolator 13 when the weight M of the car 6 acts from above in the vertical direction.
　続いて、かご６の据え付け手順について説明する。初めに、中央防振具１４が設置される。続いて、中央防振具１４の上方から、かご６が設置される。この際、中央防振具１４の上面には、かご床枠１６の下面が接する。中央防振具１４は、かご６の重量Ｍが作用することにより変形する。具体的には、中央防振具１４は、鉛直方向に縮む。次に、中央防振具１４が、締結具１５によりかご床枠１６に取り付けられる。その後、複数の隅部防振具１３の各々が、支持枠１２とかご床枠１６の間に設置される。最後に、複数の隅部防振具１３の各々が、締結具１５によりかご床枠１６に取り付けられる。 Next, the installation procedure of the basket 6 will be explained. First, the central anti-vibration tool 14 is installed. Subsequently, the car 6 is installed from above the central vibration isolator 14. At this time, the lower surface of the car floor frame 16 is in contact with the upper surface of the central vibration isolator 14. The central vibration isolator 14 is deformed by the action of the weight M of the car 6. Specifically, the central anti-vibration tool 14 contracts in the vertical direction. Next, the central vibration isolator 14 is attached to the car floor frame 16 by the fastener 15. After that, each of the plurality of corner vibration isolators 13 is installed between the support frame 12 and the car floor frame 16. Finally, each of the plurality of corner vibration isolators 13 is attached to the car floor frame 16 by the fastener 15.
　次に、図４を用いて、防振装置の設置位置について説明する。
　図４は実施の形態１におけるエレベーターの防振装置が適用されるエレベーターのかご床の平面図である。 Next, the installation position of the vibration isolator will be described with reference to FIG.
FIG. 4 is a plan view of the elevator car floor to which the elevator vibration isolator according to the first embodiment is applied.
　図４に示されるように、４つの隅部防振具１３の各々は、かご床１７の四隅の下方に設置される。２つの中央防振具１４の一方は、かご床１７の１つの辺部の中央付近の下方に設置される。２つの中央防振具１４の一方は、下枠１１の一端の上方に配置される。例えば、２つの中央防振具１４の一方は、水平投影面上において少なくとも一部が下枠１１と重なる位置に配置される。例えば、２つの中央防振具１４の一方は、水平投影面上において全体が下枠１１と重なる位置に配置される。２つの中央防振具１４の他方は、かご床１７の辺部のうち２つの中央防振具１４の一方が配置されている辺部に対向する辺部の中央付近の下方に設置される。２つの中央防振具１４の他方は、下枠１１の他端の上方に配置される。例えば、２つの中央防振具１４の他方は、水平投影面上において少なくとも一部が下枠１１と重なる位置に配置される。例えば、２つの中央防振具１４の他方は、水平投影面上において全体が下枠１１と重なる位置に配置される。 As shown in FIG. 4, each of the four corner vibration isolators 13 is installed below the four corners of the car floor 17. One of the two central vibration isolators 14 is installed below near the center of one side of the car floor 17. One of the two central vibration isolators 14 is arranged above one end of the lower frame 11. For example, one of the two central vibration isolators 14 is arranged at a position on the horizontal projection plane at least partially overlapping the lower frame 11. For example, one of the two central vibration isolators 14 is arranged at a position on the horizontal projection surface so as to be entirely overlapped with the lower frame 11. The other of the two central vibration isolators 14 is installed below the side portion of the car floor 17 near the center of the side portion facing the side portion where one of the two central vibration isolators 14 is arranged. The other of the two central vibration isolators 14 is arranged above the other end of the lower frame 11. For example, the other of the two central vibration isolators 14 is arranged at a position on the horizontal projection plane at least partially overlapping the lower frame 11. For example, the other of the two central vibration isolators 14 is arranged at a position on the horizontal projection plane so as to be entirely overlapped with the lower frame 11.
　以上で説明した実施の形態１によれば、中央防振具１４の上面は、かご６が設置される際に複数の隅部防振具１３よりも先にかご６の下面に接する。このため、かご６の重量Ｍは、中央防振具１４に作用し、隅部防振具１３に作用する荷重が軽減される。その結果、かご６を支える構造を簡易化できる。 According to the first embodiment described above, the upper surface of the central vibration isolator 14 comes into contact with the lower surface of the car 6 before the plurality of corner vibration isolators 13 when the car 6 is installed. Therefore, the weight M of the car 6 acts on the central vibration isolator 14, and the load acting on the corner vibration isolator 13 is reduced. As a result, the structure that supports the car 6 can be simplified.
　また、中央防振具１４の高さは、かご６の重量Ｍが上方から作用した場合に隅部防振具１３の高さと同等になる。この結果、かご６の重量Ｍは、複数の隅部防振具１３に作用せず、エレベーターの乗客、荷物などの積載物の重量のみが作用する。隅部防振具１３の下方にはかご６の重量Ｍによる力が作用しない。このように、中央防振具１４と複数の隅部防振具１３との機能は、互いに分離される。このため、支持枠１２に作用する荷重が軽減される。 Further, the height of the central vibration isolator 14 becomes the same as the height of the corner vibration isolator 13 when the weight M of the car 6 acts from above. As a result, the weight M of the car 6 does not act on the plurality of corner vibration isolators 13, but only the weight of the load such as the passengers of the elevator and the luggage. The force due to the weight M of the car 6 does not act below the corner vibration isolator 13. In this way, the functions of the central vibration isolator 14 and the plurality of corner vibration isolators 13 are separated from each other. Therefore, the load acting on the support frame 12 is reduced.
　従来技術においてエレベーターの構造は、かご６の重量Ｍにより支持枠１２に生じる曲げモーメントに耐えるために、エレベーターの縦枠と支持枠１２の端部との間に斜め控えを取り付ける必要があった。一方、本実施の形態１において、エレベーターの縦枠と支持枠１２との間に斜め控えを設計する場合、以下の通りとなる。 In the prior art, in the structure of the elevator, in order to withstand the bending moment generated in the support frame 12 due to the weight M of the car 6, it was necessary to attach a diagonal holder between the vertical frame of the elevator and the end of the support frame 12. On the other hand, in the first embodiment, when the diagonal restraint is designed between the vertical frame of the elevator and the support frame 12, it is as follows.
　支持枠１２との間に斜め控えとがなす角度をθ、斜め控えに鉛直下方向に働く荷重をｂ１、支持枠１２の端部に鉛直下方向に働く荷重をｂ２、支持枠１２と縦枠の接続部から支持枠１２と斜め控えの接続部までの距離をｌとする。斜め控えと支持枠１２の分担する荷重ｂ′は、ｂ′＝ｂ１＋ｂ２となる。ｂが従来技術において斜め控えと支持枠１２の分担する荷重をｂとすると、ｂ′は、ｂ′＝１/３ｂとなる。なお、斜め控えに働く引っ張り荷重は、ｂ１／ｓｉｎθとなる。ｂ２により支持枠１２に働く曲げモーメントであるｂ２×ｌは、従来技術の場合に比べて１／３となる。このため、エレベーターの縦枠と支持枠１２の端部との間に斜め控えを備える場合であっても、斜め控えの剛性を低くすることができ、軽量化することができる。 The angle formed by the diagonal restraint with the support frame 12 is θ, the load acting vertically downward on the diagonal restraint is b 1 , the load acting vertically downward on the end of the support frame 12 is b 2 , and the support frame 12 Let l be the distance from the connection portion of the vertical frame to the connection portion between the support frame 12 and the diagonally reserved portion. The load b ′ shared by the diagonal restraint and the support frame 12 is b ′ = b 1 + b 2 . Assuming that the load shared by b is diagonally reserved and the support frame 12 in the prior art, b'is b'= 1/3 b. The tensile load acting diagonally is b 1 / sin θ. The bending moment b 2 × l acting on the support frame 12 by b 2 is 1/3 of that in the case of the prior art. Therefore, even when the diagonal restraint is provided between the vertical frame of the elevator and the end of the support frame 12, the rigidity of the diagonal restraint can be lowered and the weight can be reduced.
　また、隅部防振具１３の位置を下枠１１に近づけることで、支持枠１２に働く曲げモーメントは、さらに小さくなる。例えば、隅部防振具１３が、支持枠１２と縦枠の接続部から支持枠１２と斜め控えの接続部までの間の中点に位置ずれ、支持枠１２に働く曲げモーメントはｂ′×１／２になる。支持枠１２に生じる曲げモーメントが軽減されるため、斜め控えが不要になる、または部品を軽量化もしくは部品を削減した簡易な斜め控え、測枠とすることができる。その結果、かご６を支える構造の原価低減、輸送費低減、据付時間短縮を実現することができる。 Further, by moving the position of the corner vibration isolator 13 closer to the lower frame 11, the bending moment acting on the support frame 12 becomes further smaller. For example, the corner vibration isolator 13 is displaced at the midpoint between the connection portion between the support frame 12 and the vertical frame and the connection portion between the support frame 12 and the diagonally reserved portion, and the bending moment acting on the support frame 12 is b'×. It becomes 1/2. Since the bending moment generated in the support frame 12 is reduced, the diagonal restraint becomes unnecessary, or the parts can be made lighter or the parts can be reduced to be a simple diagonal restraint or measuring frame. As a result, it is possible to reduce the cost of the structure supporting the car 6, reduce the transportation cost, and shorten the installation time.
　なお、支持枠１２の剛性を、曲げモーメントｂ′×ｌに耐え得るようにすれば、斜め控え、コーナーポストを設置する必要はない。 If the rigidity of the support frame 12 can withstand the bending moment b'× l, it is not necessary to install a corner post diagonally.
　なお、隅部防振具１３の弾性係数は、中央防振具１４の弾性係数よりも大きくてもよい。この場合、隅部防振具１３に作用する鉛直上方向からの力を小さくできる。 The elastic modulus of the corner vibration isolator 13 may be larger than the elastic modulus of the central vibration isolator 14. In this case, the force acting on the corner vibration isolator 13 from the vertically upward direction can be reduced.
　なお、隅部防振具１３の弾性係数は、中央防振具１４の弾性係数と同じでもよい。 The elastic modulus of the corner vibration isolator 13 may be the same as the elastic modulus of the central vibration isolator 14.
　なお、締結具１５は、あらかじめ定められた重量以上の荷重が中央防振具１４に鉛直方向下向きから作用した場合に、中央防振具１４の縮みを規制するようにしてもよい。この場合、エレベーターの非常止めが作動した場合、緩衝器が衝突した場合などの非常時であっても、衝撃荷重が中央防振具１４に作用しない。 Note that the fastener 15 may regulate the shrinkage of the central vibration isolator 14 when a load equal to or greater than a predetermined weight acts on the central vibration isolator 14 from downward in the vertical direction. In this case, the impact load does not act on the central vibration isolator 14 even in an emergency such as when the emergency stop of the elevator is activated or when the shock absorber collides.

FIG. 5 is a diagram of an elevator vibration isolator according to the second embodiment. The same or corresponding parts as those of the first embodiment are designated by the same reference numerals. The explanation of the relevant part is omitted.
　図５に示されるように、実施の形態２のエレベーターの防振装置は、隅部防振具１３と中央防振具１４が同じ高さであり、調整体１８を備える点が実施の形態１と異なる。 As shown in FIG. 5, in the vibration isolator of the elevator of the second embodiment, the corner vibration isolator 13 and the central vibration isolator 14 have the same height, and the adjusting body 18 is provided. Different from.
　調整体１８は、平板状の部材である。例えば、調整体１８は、金属の板状の部材である。例えば、調整体１８の厚みは、中央防振具１４に図示されないかご６の重量Ｍが上方から作用した場合に、中央防振具１４が上下方向に縮む高さと同一の高さである。調整体１８は、中央防振具１４の下面に接するように取り付けられる。調整体１８は、支持枠１２と中央防振具１４との間に挟み込まれる。例えば、調整体１８は、中央防振具１４とともに締結具１５により支持枠１２に取り付ける。 The adjusting body 18 is a flat plate-shaped member. For example, the adjusting body 18 is a metal plate-shaped member. For example, the thickness of the adjusting body 18 is the same as the height at which the central vibration isolator 14 contracts in the vertical direction when the weight M of the car 6 (not shown) acts on the central vibration isolator 14 from above. The adjusting body 18 is attached so as to be in contact with the lower surface of the central vibration isolator 14. The adjusting body 18 is sandwiched between the support frame 12 and the central vibration isolator 14. For example, the adjusting body 18 is attached to the support frame 12 by the fastener 15 together with the central vibration isolator 14.

FIG. 6 is a diagram for explaining a method of installing an elevator vibration isolator according to the second embodiment.
　図６に示されるように、エレベーターのかご６の重量Ｍが鉛直方向上方から作用すると、中央防振具１４の高さと調整体１８の厚みの和は、隅部防振具１３の高さと同等になる。 As shown in FIG. 6, when the weight M of the elevator car 6 acts from above in the vertical direction, the sum of the height of the central vibration isolator 14 and the thickness of the adjusting body 18 is equivalent to the height of the corner vibration isolator 13. become.
　以上で説明した実施の形態２によれば、調整体１８は、かご６の重量が上方から作用した場合に中央防振具１４が鉛直方向に縮む高さと同一の厚みである。このため、隅部防振具１３の高さと中央防振具１４の高さを同一にすることができる。その結果、隅部防振具１３と中央防振具１４とを共通の部材とすることができる。 According to the second embodiment described above, the adjusting body 18 has the same thickness as the height at which the central vibration isolator 14 contracts in the vertical direction when the weight of the car 6 acts from above. Therefore, the height of the corner vibration isolator 13 and the height of the central vibration isolator 14 can be made the same. As a result, the corner anti-vibration tool 13 and the central anti-vibration tool 14 can be made into a common member.
　なお、調整体１８は、中央防振具１４の上面に接するように取り付けられてもよい。この場合、調整体１８は、中央防振具１４とかご床枠１６の間に挟み込まれる。 The adjusting body 18 may be attached so as to be in contact with the upper surface of the central vibration isolator 14. In this case, the adjusting body 18 is sandwiched between the central vibration isolator 14 and the car floor frame 16.

FIG. 7 is a diagram for explaining a method of installing the vibration isolator of the elevator according to the third embodiment. The same or corresponding parts as those of the first embodiment are designated by the same reference numerals. The explanation of the relevant part is omitted.
　図７に示されるように、実施の形態３のエレベーターの防振装置は、調整ボルト１９を備える点が実施の形態１と異なる。 As shown in FIG. 7, the vibration isolator of the elevator of the third embodiment is different from the first embodiment in that the adjusting bolt 19 is provided.
　複数の調整ボルト１９の各々は、上下方向に伸長可能である。複数の調整ボルト１９の各々は、複数の隅部防振具１３の各々の上面に接するように取り付けられる。複数の調整ボルト１９の各々は、複数の隅部防振具１３の各々とかご床枠１６の間に挟み込まれる。 Each of the plurality of adjusting bolts 19 can be extended in the vertical direction. Each of the plurality of adjusting bolts 19 is attached so as to be in contact with the upper surface of each of the plurality of corner vibration isolators 13. Each of the plurality of adjusting bolts 19 is sandwiched between each of the plurality of corner vibration isolators 13 and the car floor frame 16.
　続いて、かご６の据え付け手順について説明する。初めに、中央防振具１４が設置される。続いて、中央防振具１４の上方から、かご６が設置される。この際、中央防振具１４の上面には、かご床枠１６の下面が接する。中央防振具１４は、かご６の重量Ｍが作用することにより変形する。具体的には、中央防振具１４は、上下方向に縮む。次に、中央防振具１４が、締結具１５によりかご床枠１６に取り付けられる。その後、複数の隅部防振具１３の各々が、支持枠１２とかご床枠１６の間に設置される。続いて、複数の調整ボルト１９の各々が、複数の隅部防振具１３の各々の上部に設置される。最後に、複数の調整ボルト１９の各々が、エレベーターのかご６の重量Ｍが鉛直方向上方から作用した状態の中央防振具１４の高さが、複数の隅部防振具１３の各々の高さと調整ボルト１９の高さの和が同等になるように調整される。 Next, the installation procedure of the basket 6 will be explained. First, the central anti-vibration tool 14 is installed. Subsequently, the car 6 is installed from above the central vibration isolator 14. At this time, the lower surface of the car floor frame 16 is in contact with the upper surface of the central vibration isolator 14. The central vibration isolator 14 is deformed by the action of the weight M of the car 6. Specifically, the central vibration isolator 14 contracts in the vertical direction. Next, the central vibration isolator 14 is attached to the car floor frame 16 by the fastener 15. After that, each of the plurality of corner vibration isolators 13 is installed between the support frame 12 and the car floor frame 16. Subsequently, each of the plurality of adjusting bolts 19 is installed above each of the plurality of corner vibration isolators 13. Finally, the height of the central vibration isolator 14 in a state where the weight M of the elevator car 6 acts from above in the vertical direction of each of the plurality of adjusting bolts 19 is the height of each of the plurality of corner vibration isolators 13. The sum of the height of the adjustment bolt 19 and the height of the adjustment bolt 19 are adjusted to be equal.
　以上で説明した実施の形態３によれば、調整ボルト１９は、隅部防振具１３の上面とかご６の下面の間に形成される間隙を調整する。このため、あらかじめかご６の重量Ｍを計算しなくとも、かご６から隅部防振具１３に作用する重量を作業現場で調整することができる。さらに、かご床１７の倒れを容易に修正することができる。 According to the third embodiment described above, the adjusting bolt 19 adjusts the gap formed between the upper surface of the corner vibration isolator 13 and the lower surface of the car 6. Therefore, the weight acting on the corner vibration isolator 13 from the car 6 can be adjusted at the work site without calculating the weight M of the car 6 in advance. Further, the collapse of the car floor 17 can be easily corrected.
