A portion 5c may be provided. In addition, although the elevator 1 according to the present embodiment has a configuration in which the hoisting machine 5 is arranged inside the machine room X2, the configuration is not limited thereto. For example, the elevator 1 may be configured such that the machine room X2 is not provided and the hoisting machine 5 is arranged inside the hoistway X1.
また、各図において、第１方向Ｄ１は、第１横方向Ｄ１であり、第２方向Ｄ２は、第１横方向Ｄ１と直交する横方向である第２横方向Ｄ２であり、第３方向Ｄ３は、各横方向Ｄ１，Ｄ２とそれぞれ直交する上下方向Ｄ３であり、かご２及び釣合錘４が昇降する昇降方向である。なお、特に限定されないが、乗客がかご２に出入りするために進む出入方向は、例えば、本実施形態のように、第２横方方向Ｄ２としてもよい。 Further, in each figure, the first direction D1 is the first horizontal direction D1, the second direction D2 is the second horizontal direction D2 that is orthogonal to the first horizontal direction D1, and the third direction D3. is an up-and-down direction D3 orthogonal to each of the lateral directions D1 and D2, which is the elevation direction in which the car 2 and the counterweight 4 are raised and lowered. Although not particularly limited, the direction in which passengers move to enter/exit the car 2 may be, for example, the second lateral direction D2 as in the present embodiment.
図２に示すように、釣合錘４は、例えば、錘９と、枠体１０と、錘９を枠体１０に取り付ける錘取付手段１１と、かごロープ３と枠体１０とを接続する接続部１２とを備えていてもよい。なお、釣合錘４に接続されるかごロープ３の本数は、特に限定されず、例えば、本実施形態のように、三本としてもよい。 As shown in FIG. 2 , the counterweight 4 includes, for example, a weight 9 , a frame 10 , weight attachment means 11 for attaching the weight 9 to the frame 10 , and a connection for connecting the cage rope 3 and the frame 10 . A portion 12 may be provided. The number of cage ropes 3 connected to the counterweight 4 is not particularly limited, and may be, for example, three as in the present embodiment.
かごロープ３は、例えば、変形可能なロープ本体（例えば、ワイヤロープ等）３ａと、ロープ本体３ａの端部に連結され、釣合錘４の接続部１２に接続されるロープ端部３ｂとを備えていてもよい。なお、特に限定されないが、ロープ端部３ｂは、例えば、ロープ本体３ａよりも、剛性を有していることが好ましい。 The cage rope 3 includes, for example, a deformable rope body (for example, a wire rope) 3a and a rope end 3b connected to the end of the rope body 3a and connected to the connection part 12 of the counterweight 4. may be provided. In addition, although not particularly limited, it is preferable that the rope end portion 3b has higher rigidity than the rope main body 3a, for example.
枠体１０は、例えば、本実施形態のように、第１横方向Ｄ１へ延びる上枠部１３と、第１横方向Ｄ１へ延び、上枠部１３よりも下方に配置される下枠部１４と、上下方向Ｄ３へ延び、上枠部１３と下枠部１４とを接続する縦枠部１５，１５とを備えていてもよい。これにより、枠体１０は、第２横方向Ｄ２視において、矩形の無端環状に形成されている。 For example, as in the present embodiment, the frame 10 includes an upper frame portion 13 extending in the first horizontal direction D1 and a lower frame portion 14 extending in the first horizontal direction D1 and arranged below the upper frame portion 13. and vertical frame portions 15 , 15 extending in the vertical direction D<b>3 and connecting the upper frame portion 13 and the lower frame portion 14 . Thereby, the frame body 10 is formed in a rectangular endless ring shape when viewed in the second lateral direction D2.
特に限定されないが、例えば、本実施形態のように、錘９は、板状の錘片９ａを複数備えており、複数の錘片９ａは、下枠部１４の上に、上下方向Ｄ３に積まれている、という構成でもよい。これにより、例えば、錘片９ａの個数が変更されることによって、錘９の重量、即ち、釣合錘４の重量を変更することができる。 Although not particularly limited, for example, as in the present embodiment, the weight 9 includes a plurality of plate-like weight pieces 9a, and the plurality of weight pieces 9a are stacked on the lower frame portion 14 in the vertical direction D3. The configuration may be such that it is included. Thus, for example, by changing the number of weight pieces 9a, the weight of the weight 9, that is, the weight of the counterweight 4 can be changed.
図３～図６に示すように、上枠部１３は、例えば、第２横方向Ｄ２で並べられる第１枠板１３ａ及び第２枠板１３ｂと、第１枠板１３ａ及び第２枠板１３ｂの各下端部に固定され、第１枠板１３ａと第２枠板１３ｂとを接続する接続枠板１３ｃとを備えていてもよい。接続枠板１３ｃは、例えば、溶接や固定材（例えば、ボルト・ナット）等によって、各枠板１３ａ，１３ｂに固定されていてもよい。 As shown in FIGS. 3 to 6, the upper frame portion 13 includes, for example, a first frame plate 13a and a second frame plate 13b arranged in the second horizontal direction D2, and a first frame plate 13a and a second frame plate 13b. A connection frame plate 13c may be provided which is fixed to each lower end of the frame plate 13a and connects the first frame plate 13a and the second frame plate 13b. The connection frame plate 13c may be fixed to each of the frame plates 13a and 13b by, for example, welding or fixing materials (for example, bolts and nuts).
接続部１２は、例えば、本実施形態のように、第２横方向Ｄ２で上枠部１３を挟む第１挟み部１６及び第２挟み部１７と、上枠部１３よりも上方に配置され、かごロープ３が接続されるロープ接続部１８と、上枠部１３に下方から引っ掛けられる引掛部１９と、かごロープ３をロープ接続部１８に取り付けるロープ取付手段２０とを備えていてもよい。 For example, as in the present embodiment, the connecting portion 12 is arranged above the first sandwiching portion 16 and the second sandwiching portion 17 sandwiching the upper frame portion 13 in the second lateral direction D2 and the upper frame portion 13, A rope connecting portion 18 to which the cage rope 3 is connected, a hooking portion 19 to be hooked on the upper frame portion 13 from below, and a rope mounting means 20 for mounting the cage rope 3 to the rope connecting portion 18 may be provided.
そして、接続部１２は、例えば、本実施形態のように、一対の挟み部１６，１７とロープ接続部１８と引掛部１９とによって、第１横方向Ｄ１視で、矩形状の無端環状に形成される環状部１２ａを備えていてもよい。これにより、ロープ接続部１８は、環状部１２ａの上部を構成し、引掛部１９は、環状部１２ａの下部を構成し、上枠部１３は、環状部１２ａの内部に配置される。 The connecting portion 12 is, for example, as in the present embodiment, formed into a rectangular endless ring as viewed in the first lateral direction D1 by a pair of sandwiching portions 16 and 17, a rope connecting portion 18, and a hook portion 19. An annular portion 12a may be provided. Thereby, the rope connecting portion 18 constitutes the upper portion of the annular portion 12a, the hook portion 19 constitutes the lower portion of the annular portion 12a, and the upper frame portion 13 is arranged inside the annular portion 12a.
したがって、引掛部１９が上枠部１３を下方から引っ掛けられることによって、枠体１０は、吊り上げられる。その結果、枠体１０とかごロープ３とは、接続部１２によって接続される。しかも、引掛部１９が上枠部１３に下方から引っ掛けられていることに対して、上枠部１３が環状部１２ａの内部に配置されているため、接続部１２が上枠部１３から取り外れることを抑制することができる。 Therefore, the frame body 10 is lifted by hooking the upper frame portion 13 from below with the hook portion 19 . As a result, the frame 10 and the car rope 3 are connected by the connecting portion 12 . Moreover, since the hook portion 19 is hooked on the upper frame portion 13 from below, the connecting portion 12 can be removed from the upper frame portion 13 because the upper frame portion 13 is arranged inside the annular portion 12a. can be suppressed.
接続部１２は、例えば、本実施形態のように、一対の挟み部１６，１７とロープ接続部１８とを固定する第１ネジ機構２１を備えていてもよい。そして、第１ネジ機構２１は、例えば、本実施形態のように、第１横方向Ｄ１視において、環状部１２ａの外部に配置されていてもよい。これにより、第１ネジ機構２１の操作を環状部１２ａの外部で行うことができるため、例えば、第１ネジ機構２１の操作を容易にすることができる。 The connection portion 12 may include, for example, a first screw mechanism 21 that fixes the pair of clip portions 16 and 17 and the rope connection portion 18 as in the present embodiment. And the 1st screw mechanism 21 may be arrange|positioned outside the annular part 12a, for example like this embodiment in the 1st horizontal direction D1 view. As a result, the operation of the first screw mechanism 21 can be performed outside the annular portion 12a, so that, for example, the operation of the first screw mechanism 21 can be facilitated.
ロープ接続部１８は、例えば、本実施形態のように、かごロープ３に接続される板状の接続本体部１８ａと、接続本体部１８ａから上方へ突出する上突出部１８ｂ，１８ｂとを備えていてもよい。そして、第１ネジ機構２１は、例えば、本実施形態のように、挟み部１６，１７と上突出部１８ｂとに挿通される雄ネジ材２１ａと、雄ネジ材２１ａと螺合する雌ネジ材２１ｂとを備えていてもよい。 For example, as in the present embodiment, the rope connection portion 18 includes a plate-like connection body portion 18a connected to the cage rope 3, and upper projecting portions 18b, 18b projecting upward from the connection body portion 18a. may The first screw mechanism 21 includes, for example, as in the present embodiment, a male screw member 21a inserted through the clamping portions 16 and 17 and the upper protruding portion 18b, and a female screw member screwed together with the male screw member 21a. 21b.
なお、特に限定されないが、接続本体部１８ａは、例えば、本実施形態のように、薄い上板材の下に厚い下板材が固定されることによって、形成されていてもよい。例えば、本実施形態のように、上板材は、接続本体部１８ａ及び上突出部１８ｂ，１８ｂを備えており、下板材は、接続本体部１８ａのみを備えている、という構成でもよい。 Although not particularly limited, the connecting body portion 18a may be formed, for example, by fixing a thick lower plate member under a thin upper plate member, as in the present embodiment. For example, as in the present embodiment, the upper plate member may include the connecting body portion 18a and the upper projecting portions 18b, 18b, and the lower plate member may include only the connecting body portion 18a.
また、接続部１２は、例えば、本実施形態のように、一対の挟み部１６，１７と引掛部１９とを固定する第２ネジ機構２２を備えていてもよい。そして、第２ネジ機構２２は、例えば、本実施形態のように、第１横方向Ｄ１視において、環状部１２ａの外部に配置されていてもよい。これにより、第２ネジ機構２２の操作を環状部１２ａの外部で行うことができるため、例えば、第２ネジ機構２２の操作を容易にすることができる。 Moreover, the connection part 12 may be provided with the 2nd screw mechanism 22 which fixes a pair of clamp parts 16 and 17 and the hook part 19 like this embodiment, for example. Then, for example, the second screw mechanism 22 may be arranged outside the annular portion 12a as viewed in the first lateral direction D1, as in the present embodiment. As a result, the operation of the second screw mechanism 22 can be performed outside the annular portion 12a, so that, for example, the operation of the second screw mechanism 22 can be facilitated.
引掛部１９は、例えば、本実施形態のように、上枠部１３の接続枠板１３ｃに引っ掛けられる板状の引掛本体部１９ａと、引掛本体部１９ａから下方へ突出する下突出部１９ｂ，１９ｂとを備えていてもよい。そして、第２ネジ機構２２は、例えば、本実施形態のように、挟み部１６，１７と下突出部１９ｂとに挿通される雄ネジ材２２ａと、雄ネジ材２２ａと螺合する雌ネジ材２２ｂとを備えていてもよい。 For example, as in the present embodiment, the hook portion 19 includes a plate-like hook body portion 19a that is hooked on the connection frame plate 13c of the upper frame portion 13, and lower protruding portions 19b, 19b that protrude downward from the hook body portion 19a. and may be provided. The second screw mechanism 22 includes, for example, a male screw member 22a inserted through the clip portions 16 and 17 and the lower protruding portion 19b and a female screw member screwed together with the male screw member 22a, as in the present embodiment. 22b.
ところで、引掛部１９が上枠部１３に下方から引っ掛かることによって、引掛部１９は、上枠部１３に接続されている（即ち、完全に固定されていない）。したがって、引掛部１９が上枠部１３に対して位置ずれすることによって、接続部１２が上枠部１３に対して位置ずれする場合がある。 By the way, the hook portion 19 is connected to the upper frame portion 13 by hooking the hook portion 19 on the upper frame portion 13 from below (that is, it is not completely fixed). Therefore, the connection portion 12 may be displaced with respect to the upper frame portion 13 due to the positional displacement of the hook portion 19 with respect to the upper frame portion 13 .
そこで、接続部１２は、例えば、本実施形態のように、上枠部１３に上方から当たる上規制部２３を備えていてもよい。これにより、上規制部２３が上枠部１３の枠板１３ａ，１３ｂの上端に上方から当たるため、上枠部１３に対する接続部１２の下方向への変位が規制される。したがって、上規制部２３と引掛部１９とが上枠部１３を上下方向Ｄ３で挟んでいるため、接続部１２が上枠部１３に対して上下方向Ｄ３に変位することを抑制することができる。 Therefore, the connecting portion 12 may include, for example, an upper restricting portion 23 that contacts the upper frame portion 13 from above, as in the present embodiment. As a result, the upper restricting portion 23 hits the upper ends of the frame plates 13a and 13b of the upper frame portion 13 from above, so that the downward displacement of the connecting portion 12 with respect to the upper frame portion 13 is restricted. Therefore, since the upper restricting portion 23 and the hook portion 19 sandwich the upper frame portion 13 in the vertical direction D3, it is possible to prevent the connecting portion 12 from being displaced in the vertical direction D3 with respect to the upper frame portion 13. .
上規制部２３は、例えば、本実施形態のように、挟み部１６，１７から突出していてもよい。特に限定されないが、上規制部２３は、本実施形態のように、挟み部１６，１７と螺合する雄ネジ材（例えば、ボルト）で構成されていてもよい。 For example, the upper restricting portion 23 may protrude from the clip portions 16 and 17 as in the present embodiment. Although not particularly limited, the upper restricting portion 23 may be composed of a male screw material (for example, a bolt) that screws together with the clamping portions 16 and 17 as in the present embodiment.
さらに、接続部１２は、例えば、本実施形態のように、上枠部１３に第１横方向Ｄ１で当たる横規制部２４，２５を備えていてもよい。横規制部２４，２５は、例えば、本実施形態のように、上枠部１３の接続枠板１３ｃを第１横方向Ｄ１で挟むように、第１横規制部２４及び第２横規制部２５を備えていてもよい。 Furthermore, the connecting portion 12 may be provided with lateral restricting portions 24 and 25 that contact the upper frame portion 13 in the first lateral direction D1, for example, as in the present embodiment. The lateral restricting portions 24 and 25 are, for example, the first lateral restricting portion 24 and the second lateral restricting portion 25 so as to sandwich the connection frame plate 13c of the upper frame portion 13 in the first lateral direction D1 as in the present embodiment. may be provided.
これにより、横規制部２４，２５が上枠部１３の接続枠板１３ｃに第１横方向Ｄ１から当たるため、上枠部１３に対する接続部１２の第１横方向Ｄ１への変位が規制される。そして、第１横規制部２４と第２横規制部２５とが上枠部１３の接続枠板１３ｃを第１横方向Ｄ１で挟んでいるため、接続部１２が上枠部１３に対して第１横方向Ｄ１に変位することを抑制することができる。 As a result, the lateral restricting portions 24 and 25 abut against the connecting frame plate 13c of the upper frame portion 13 in the first lateral direction D1, thereby restricting the displacement of the connecting portion 12 with respect to the upper frame portion 13 in the first lateral direction D1. . Since the connecting frame plate 13 c of the upper frame portion 13 is sandwiched between the first lateral restricting portion 24 and the second lateral restricting portion 25 in the first lateral direction D<b>1 , the connecting portion 12 is positioned in the first lateral direction D<b>1 with respect to the upper frame portion 13 . Displacement in one lateral direction D1 can be suppressed.
横規制部２４，２５は、例えば、本実施形態のように、挟み部１６，１７から突出していてもよい。特に限定されないが、横規制部２４，２５は、本実施形態のように、挟み部１６，１７と螺合する雄ネジ材（例えば、ボルト）で構成されていてもよい。 For example, the lateral restricting portions 24 and 25 may protrude from the clip portions 16 and 17 as in the present embodiment. Although not particularly limited, the lateral regulating portions 24 and 25 may be composed of male screw members (for example, bolts) that screw together with the clamping portions 16 and 17 as in the present embodiment.
なお、本実施形態においては、接続部１２の挟み部１６，１７と上枠部１３との第２横方向Ｄ２の間に、僅かな隙間が存在しているが、特に限定されない。例えば、一対の挟み部１６，１７は、それぞれ上枠部１３に加圧して接触していてもよい。これにより、一対の挟み部１６，１７が上枠部１３に対して変位することを抑制することができる。 In addition, in the present embodiment, a slight gap exists between the clamping portions 16 and 17 of the connection portion 12 and the upper frame portion 13 in the second lateral direction D2, but the gap is not particularly limited. For example, the pair of pinching portions 16 and 17 may be in contact with the upper frame portion 13 under pressure. Thereby, it is possible to suppress the pair of pinching portions 16 and 17 from being displaced with respect to the upper frame portion 13 .
