Abstract

<P>PROBLEM TO BE SOLVED: To provide an elevator car, capable of easily limiting compression deformation of a vibration control means 7 to support a car floor 11 due to load weight on a car, and preventing generation of stress concentration due to the load weight in limiting compression deformation of the vibration control means 7. <P>SOLUTION: In this elevator car, transmission of vibration to the car floor 11 is reduced by installing the vibration control means 7 between a car floor support frame 5 supported by a car frame 1 suspended by a main cable 16, and extended in the horizontal direction, and the car floor 11 forming a floor surface of a cage 14. Between the car floor support frame 5 and the car floor 11, flat spacers 17 are provided, so that the spacers 17 are pressed to let the load weight shared by the vibration control means 7 and the spacers 17 when the vibration control means 7 is compressed by the load weight to narrow the interval between the car floor support frame 5 and the car floor 11. The load is thus shared to limit compression deformation of the vibration control means 7. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

この発明は、かご室を支持する防振手段の圧縮変形を制限するようにしたエレベータのかごに係るものである。   The present invention relates to an elevator car that restricts the compressive deformation of vibration isolating means that supports a car room.

エレベータのかごは、かご枠から伝達される振動を軽減するために、防振手段を介して支持されている。図５及び図６は、特許文献１に記載されたエレベータのかご床装置と同様の構成を有する従来のエレベータのかごを示す。
図５は、従来のエレベータのかごの概要を示す側面図である。かごの左右には、縦枠２が垂設されている。この縦枠２の双方の上端部は上枠３によって連結されている。上枠３には主索１６が係止されている。また、縦枠２の双方の下端部は下枠４によって連結されている。この下枠４には水平方向へ延設された方形のかご床支持枠３５が取り付けられている。このかご床支持枠３５は、ブレース１５によって縦枠２にも係止されている。かご床支持枠３５の各角部には防振ゴム３７が取り付けられている。この防振ゴム３７に支持されてかご床枠３６が取り付けられている。防振ゴム３７に隣接してジャッキボルト４１が立設されている。 The elevator car is supported through vibration isolation means in order to reduce vibrations transmitted from the car frame. 5 and 6 show a conventional elevator car having the same configuration as that of the elevator car floor apparatus described in Patent Document 1. FIG.
FIG. 5 is a side view showing an outline of a conventional elevator car. Vertical frames 2 are suspended from the right and left sides of the car. Both upper ends of the vertical frame 2 are connected by an upper frame 3. A main rope 16 is locked to the upper frame 3. Further, both lower ends of the vertical frame 2 are connected by a lower frame 4. A square car floor support frame 35 extending in the horizontal direction is attached to the lower frame 4. The car floor support frame 35 is also locked to the vertical frame 2 by the brace 15. Anti-vibration rubber 37 is attached to each corner of the car floor support frame 35. A car floor frame 36 is attached to the anti-vibration rubber 37. A jack bolt 41 is erected adjacent to the vibration isolating rubber 37.

図６は、図５に示すエレベータのかごの要部を拡大した側面図である。即ち、防振ゴム３７とかご床枠３６の間にはかご床枠３６を水平にするためにスペーサ４０が介挿されている。このスペーサ４０の介挿作業は、かご床枠３６側のボルト３８及びナット３９を緩めた後、ナット４２を螺合させてジャッキボルト４１によってかご床枠３６を押し上げる。防振ゴム３７とかご床枠３６との間に生じた隙間に必要数のスペーサ４０を挿入する。次に、ボルト３８及びナット３９を締めつけて、かご床枠３６と防振ゴム３７とを固定する。ナット４２を緩めてジャッキボルト４１を下降させて防振ゴム３７を有効にする。更に、ジャッキボルト４１の上端とかご床枠３６の下面との間隔を、防振ゴム３７の許容たわみとなる寸法δ１に設定した後、ナット４２を締め付けてジャッキボルト４１を固定する。   6 is an enlarged side view of a main part of the elevator car shown in FIG. In other words, the spacer 40 is interposed between the anti-vibration rubber 37 and the car floor frame 36 in order to make the car floor frame 36 horizontal. The spacer 40 is inserted by loosening the bolt 38 and the nut 39 on the car floor frame 36 side, and then screwing the nut 42 and pushing up the car floor frame 36 by the jack bolt 41. A necessary number of spacers 40 are inserted into a gap formed between the vibration isolating rubber 37 and the car floor frame 36. Next, the bolt 38 and the nut 39 are tightened to fix the car floor frame 36 and the vibration isolating rubber 37. The nut 42 is loosened and the jack bolt 41 is lowered to activate the anti-vibration rubber 37. Further, after setting the distance between the upper end of the jack bolt 41 and the lower surface of the car floor frame 36 to a dimension δ1 that allows the vibration isolating rubber 37 to be allowed, the nut 42 is tightened to fix the jack bolt 41.

特開２００２−３６２８５７号公報（段落番号１６、１７、図１）JP 2002-362857 A (paragraph numbers 16 and 17, FIG. 1)

従来のエレベータのかごは、上記のとおり構成されており、過重な積荷がかごに積載されて防振ゴム３７が圧縮されたとしても、ジャッキボルト４１の上端がかご床枠３６の下面に突き当るので、かご床支持枠３５とかご床枠３６の間隔は寸法δ１を越えて減少することはない。このため、防振ゴム３７は許容たわみを越えて圧縮変形することはない。
しかしながら、ジャッキボルト４１のねじ込みにより上記寸法δ１を設定するので、その設定作業に時間がかかる、という問題があった。
また、ジャッキボルト４１の上端がかご床枠３６の下面に突き当るのは、防振ゴム３７の許容たわみ量を越える大きな荷重がかご床枠３６に作用した場合である。この場合は、上記荷重の一部がジャッキボルト４１の上端にかかり、狭い面積で上記荷重を受けることになる。このため、かご床支持枠３５及びかご床枠３６に応力集中が生じる、という問題もあった。 The conventional elevator car is configured as described above, and even if an excessive load is loaded on the car and the anti-vibration rubber 37 is compressed, the upper end of the jack bolt 41 hits the lower surface of the car floor frame 36. Therefore, the distance between the car floor support frame 35 and the car floor frame 36 does not decrease beyond the dimension δ1. For this reason, the anti-vibration rubber 37 does not compress and deform beyond the allowable deflection.
However, since the dimension δ1 is set by screwing the jack bolt 41, there is a problem that the setting work takes time.
The upper end of the jack bolt 41 abuts against the lower surface of the car floor frame 36 when a large load exceeding the allowable deflection amount of the vibration isolating rubber 37 acts on the car floor frame 36. In this case, a part of the load is applied to the upper end of the jack bolt 41, and the load is received in a small area. For this reason, there is also a problem that stress concentration occurs in the car floor support frame 35 and the car floor frame 36.

この発明は、上記問題点を解決するためになされたものであり、かごの積載荷重によってかご床を支持する防振手段の圧縮変形を容易に制限することができるエレベータのかごを得ることを目的とする。
また、応力集中を生じさせることなく上記防振手段の圧縮変形を制限することができるエレベータのかごを得ることを目的とする。 The present invention has been made to solve the above-described problems, and an object of the present invention is to obtain an elevator car that can easily limit the compression deformation of the vibration isolating means that supports the car floor by the load of the car. And
It is another object of the present invention to provide an elevator car that can limit the compression deformation of the vibration isolating means without causing stress concentration.

主索に吊持されたかご枠に支持されて水平方向へ延設されたかご床支持枠とかご室の床面を形成するかご床との間に防振手段を取り付けて上記かご床への振動の伝達を軽減するようにしたエレベータのかごの上記かご床支持枠と上記かご床との間に平板状のはさみ金を介在させて積載荷重によって防振手段が圧縮されてかご床支持枠とかご床との間隔が狭められると、はさみ金が挟まれて押圧されて積載荷重が防振手段とはさみ金によって分担されることにより防振手段の圧縮変形を制限するようにしたものである。   Anti-vibration means is installed between the car floor support frame that is supported by the car frame suspended from the main rope and extends in the horizontal direction, and the car floor that forms the floor of the car room. A flat plate liner is interposed between the car floor support frame and the car floor of the elevator car designed to reduce vibration transmission. When the distance from the floor is narrowed, the liner is sandwiched and pressed, and the load is shared by the vibration isolator and the liner to limit the compression deformation of the vibration isolator.

この発明によれば、かご床支持枠とかご床との間に平板状のはさみ金を介在させる、という簡単な作業によって、防振手段の圧縮変形を容易に制限することができる、という効果を奏する。
また、はさみ金を平板状にしたので、広い面積で荷重を受けることになる。このため、はさみ金が積載荷重を分担しても応力集中は生じない、という効果も併せて奏する。 According to this invention, the effect that the compression deformation of the vibration isolating means can be easily limited by a simple operation of interposing a flat liner between the car floor support frame and the car floor. Play.
Further, since the liner is formed into a flat plate shape, the load is received in a wide area. For this reason, there is also an effect that stress concentration does not occur even if the liners share the load.

以下、図面を参照して、この発明の実施の形態について説明する。なお、各図中、同一又は相当する部分には同一符号を付し、説明の重複を省いた。
実施の形態１．
図１及び図２は、この発明の実施の形態１を示す。
図１は、エレベータのかごの側面図で、かごの左右には、縦枠２が垂設されている。双方の縦枠２の上端部は上枠３によって連結されている。また、双方の縦枠２の下端部は下枠４によって連結されている。縦枠２と上枠３と下枠４は、方形に形成されてかご枠１を構成する。このかご枠１は、上枠３に係止された主索１６によって吊持されている。
下枠４の左右の縦枠２に接近した部位には、奥行方向へ向けて水平に一対のかご床支持枠５が延設されている。左右のかご床支持枠５の両端部は、連結枠６によって相互に連結されると共に、ブレース１５によって縦枠２にも係止されている。 Embodiments of the present invention will be described below with reference to the drawings. In addition, in each figure, the same code | symbol is attached | subjected to the part which is the same or it corresponds, and duplication of description was omitted.
Embodiment 1 FIG.
1 and 2 show Embodiment 1 of the present invention.
FIG. 1 is a side view of an elevator car, and vertical frames 2 are vertically provided on the left and right sides of the car. The upper ends of both vertical frames 2 are connected by an upper frame 3. Further, the lower ends of both vertical frames 2 are connected by a lower frame 4. The vertical frame 2, the upper frame 3, and the lower frame 4 are formed in a square shape to constitute the car frame 1. The car frame 1 is suspended by a main rope 16 locked to the upper frame 3.
A pair of car floor support frames 5 extend horizontally in the depth direction at a portion of the lower frame 4 that is close to the left and right vertical frames 2. Both ends of the left and right car floor support frames 5 are connected to each other by a connecting frame 6 and are also locked to the vertical frame 2 by braces 15.

かご床支持枠５の各端部には防振ゴム７が取り付けられている。この防振ゴム７に支持されてかご床枠８が取り付けられている。このかご床枠８は、かご床支持枠５と対峙して延設されていて、かご床板１０の左右を縁取っている。かごの奥行方向最後部には、かご床枠９が左右のかご床枠８間に跨設されていて、かご床板１０を縁取っている。かご床枠８、かご床枠９及びかご床板１０は、かご室１４の床面を形成するかご床１１を構成する。かご床枠８、９には、かご室側壁１２が立設されている。また、前面にはかご戸１３が設けられていてかご室１４を構成している。
かご床支持枠５の上面には自己の磁力によって相互に接着された平板状の磁気はさみ金１７が固着されている。 Anti-vibration rubber 7 is attached to each end of the car floor support frame 5. A car floor frame 8 is attached to the anti-vibration rubber 7. The car floor frame 8 extends opposite to the car floor support frame 5 and borders the left and right sides of the car floor plate 10. At the rearmost part in the depth direction of the car, a car floor frame 9 is straddled between the left and right car floor frames 8 and borders the car floor board 10. The car floor frame 8, the car floor frame 9, and the car floor board 10 constitute a car floor 11 that forms the floor surface of the car room 14. A car room side wall 12 is erected on the car floor frames 8 and 9. Further, a car door 13 is provided on the front surface to constitute a car room 14.
A flat magnetic liner 17 bonded to each other by its own magnetic force is fixed to the upper surface of the car floor support frame 5.

図２は、図１のＩＩ−ＩＩ線断面を矢視した縦断面図である。この図に基いて構成要素を更に詳述すると、かご床支持枠５は、断面がコ字状に屈曲されて開口をかごの中央部へ向けて延設されている。連結枠６は、かご床支持枠５の下部フランジ５ａの下面に、ボルト７ａによって取り付けられている。また、防振ゴム７はかご床支持枠５の下部フランジ５ａの上面に、ボルト７ａによって連結枠６と共に固定されている。かご床枠８は、断面がＳ字状に屈曲されて下部フランジ８ａ、中間棚部８ｂ及び上部フランジ８ｃからなっている。このかご床枠８は、下部の開口をかごの外側へ向け、下部フランジ８ａを防振ゴム７の上面に載せてボルト７ａによって固定されている。 2 is a longitudinal sectional view taken along the line II-II in FIG. The components will be described in more detail with reference to this figure. The car floor support frame 5 is bent in a U-shaped cross section and the opening extends toward the center of the car. The connecting frame 6 is attached to the lower surface of the lower flange 5a of the car floor support frame 5 with bolts 7a. Further, the anti-vibration rubber 7 is fixed to the upper surface of the lower flange 5a of the car floor support frame 5 together with the connecting frame 6 by bolts 7a. The car floor frame 8 is bent into an S shape in cross section, and includes a lower flange 8a, an intermediate shelf portion 8b, and an upper flange 8c. The car floor frame 8 is fixed by bolts 7 a with the lower opening facing the outside of the car and the lower flange 8 a placed on the upper surface of the vibration-proof rubber 7.

かご床枠９は、断面がコ字状に屈曲され、両端が左右のかご枠８の中間棚部８ｂに載置されて跨設されている。かご床枠８の上部フランジ８ｃの上面には、かご室側壁１２が立設されている。図示はしないが、かご床枠９も同様にコ字状に屈曲され、後部のかご室側壁１２が立設されている。
かご床支持枠５の上部フランジ５ｂの上面には磁化された平板からなる磁気はさみ金１７が相互に吸着し合って積み重ねられている。このため、緩衝ゴム１８が自在に伸縮できる距離は、磁気はさみ金１７の最上面からかご床枠８の中間棚部８ｂの下面までの寸法δ１となる。この寸法δ１は、防振ゴム７の許容たわみに等しい値に設定される。従って、過大な荷重がかご床１１に積載されても、防振ゴム７は許容たわみを越えて圧縮変形することはない。なお、かご床枠８の中間棚部８ｂの下面の磁気はさみ金１７が当接する部位には、緩衝ゴム１８が貼着されている。このため、磁気はさみ金１７が中間棚部８ｂ側へ転移することはない。 The car floor frame 9 is bent in a U-shaped cross section, and both ends are placed on and straddled on the intermediate shelf portion 8 b of the left and right car frames 8. A car room side wall 12 is erected on the upper surface of the upper flange 8 c of the car floor frame 8. Although not shown, the car floor frame 9 is similarly bent in a U shape, and a rear cab side wall 12 is erected.
Magnetic liners 17 made of magnetized flat plates are stacked on the upper surface of the upper flange 5b of the car floor support frame 5 while adsorbing each other. For this reason, the distance that the buffer rubber 18 can freely expand and contract is the dimension δ1 from the uppermost surface of the magnetic liner 17 to the lower surface of the intermediate shelf 8b of the car floor frame 8. The dimension δ1 is set to a value equal to the allowable deflection of the vibration isolating rubber 7. Therefore, even if an excessive load is loaded on the car floor 11, the anti-vibration rubber 7 does not compress and deform beyond the allowable deflection. A buffer rubber 18 is attached to a portion of the lower surface of the intermediate shelf portion 8b of the car floor frame 8 where the magnetic liner 17 abuts. For this reason, the magnetic liner 17 does not transfer to the intermediate shelf 8b side.

上記実施の形態１によれば、かご床支持枠５の上部フランジ５ｂ上に平板状の磁気はさみ金１７を吸着させて積み重ねたので、積載荷重によって防振ゴム７が圧縮されてかご床支持枠５とかご床枠８との間隔が狭められると、磁気はさみ金１７が挟まれて押圧される。このため、積載荷重が防振ゴム７と磁気はさみ金１７によって分担されて支持される。この荷重分担によって防振ゴム７の圧縮変形が制限される。
特に、磁気はさみ金１７からかご床枠８の中間棚部８ｂの下面までの距離を防振ゴム７の許容たわみである寸法δ１に設定したので、防振ゴム７が許容たわみを越えて圧縮変形することはない。
しかも、磁気はさみ金１７の取付けは、かご床支持枠５に吸着させて積み重ねる、という簡単な作業であるので、エレベータの据付け現場の実状に応じて防振ゴム７の圧縮変形を容易に制限することができる。
更に、磁気はさみ金１７を平板状にしたので、広い面積で荷重を受けることになる。このため、磁気はさみ金１７が積載荷重を分担しても応力集中は生じない。特に、各防振ゴム７に対して、それぞれ２組の磁気はさみ金１７を積み重ねて配置したので、荷重の分散を徹底させることができる。 According to the first embodiment, since the flat magnetic liners 17 are attracted and stacked on the upper flange 5b of the car floor support frame 5, the anti-vibration rubber 7 is compressed by the loaded load, and the car floor support frame. When the distance between the car 5 and the car floor frame 8 is narrowed, the magnetic liner 17 is sandwiched and pressed. For this reason, the loaded load is shared and supported by the vibration isolating rubber 7 and the magnetic liner 17. This load sharing restricts the compression deformation of the anti-vibration rubber 7.
In particular, since the distance from the magnetic liner 17 to the lower surface of the intermediate shelf portion 8b of the car floor frame 8 is set to the dimension δ1 which is the allowable deflection of the vibration isolating rubber 7, the vibration isolating rubber 7 is compressed and deformed beyond the allowable deflection. Never do.
In addition, since the magnetic liner 17 is simply attached to the car floor support frame 5 and stacked, the compression deformation of the anti-vibration rubber 7 is easily limited in accordance with the actual situation of the elevator installation site. be able to.
Further, since the magnetic liner 17 is formed into a flat plate shape, the load is received over a wide area. For this reason, even if the magnetic liner 17 shares the load, no stress concentration occurs. In particular, since two sets of magnetic liners 17 are stacked on each anti-vibration rubber 7, the load can be thoroughly distributed.

実施の形態２．
この実施の形態２は、磁気はさみ金１７に替えてＣ形はさみ金２５によって防振ゴム７の圧縮変形を制限するようにしたものである。
図３及び図４は、この発明の実施の形態２を示す。図３は、Ｃ形はさみ金２５を用いたエレベータのかごの要部を示し、図１のＩＩ−ＩＩ線相当断面を矢視した縦断面図である。図３において、かご床支持枠５の上部フランジ５ｂの直下の立上り部分に長手を水平方向へ向けたスリット５ｃが形成されている。平板をＣ字状に屈曲させて深溝が形成されたＣ形はさみ金２５を、外層のＣ形はさみ金２５の深溝内に順次挿入して積層する。
ここで、Ｃ形はさみ金２５の積層数について述べる。かご床１１が無負荷のときに、かご床支持枠５の上部フランジ５ｂの上面から中間棚部８ｂの下面までを寸法δ０とし、防振ゴム７の許容たわみを寸法δ１とすると、積層されたＣ形はさみ金２５の厚さ寸法δｃは、δｃ＝δ０−δ１となるように設定する。 Embodiment 2. FIG.
In the second embodiment, the compression deformation of the anti-vibration rubber 7 is limited by a C-shaped liner 25 instead of the magnetic liner 17.
3 and 4 show a second embodiment of the present invention. FIG. 3 is a longitudinal sectional view showing the main part of the elevator car using the C-shaped liner 25, as viewed from the section corresponding to the line II-II in FIG. In FIG. 3, a slit 5 c having a longitudinal direction in the horizontal direction is formed at a rising portion immediately below the upper flange 5 b of the car floor support frame 5. The C-shaped liner 25 having a deep groove formed by bending the flat plate into a C shape is sequentially inserted into the deep groove of the outer C-shaped liner 25 and laminated.
Here, the number of stacked C-shaped liners 25 will be described. When the car floor 11 is unloaded, it is assumed that the dimension from the upper surface of the upper flange 5b of the car floor support frame 5 to the lower surface of the intermediate shelf 8b is δ0, and the allowable deflection of the antivibration rubber 7 is δ1. The thickness dimension δc of the C-shaped liner 25 is set so that δc = δ0−δ1.

次に、図４に従って、積層されたＣ形はさみ金２５をかご床支持枠５に取り付ける手順について述べる。
図４（ａ）に示したとおり、Ｃ形はさみ金２５を積層する。図４（ｂ）に示すとおり、積層されたＣ形はさみ金２５の下部フランジ２５ｄをスリット５ｃに挿入貫通させて下部フランジ２５ｄをかご床支持枠５の背面側へ突出させる。このとき、かご床支持枠５の上部フランジ５ｂは最内層のＣ形はさみ金２５の深溝内に収納される。上部フランジ２５ｕはかご床支持枠５の上部フランジ５ｂの上位に位置して、かご床枠８の中間棚部８ｂの間に介在する。図４（ｃ）に示すとおり、かご床支持枠５の背面側へ突出した上部フランジ２５ｕ及び下部フランジ２５ｄの開放端を、金槌２６で打ち付けて下方へ曲げて上部フランジ５ｂを把持させてＣ形はさみ金２５を固着させる。 Next, a procedure for attaching the laminated C-shaped liner 25 to the car floor support frame 5 will be described with reference to FIG.
As shown in FIG. 4A, a C-shaped liner 25 is laminated. As shown in FIG. 4 (b), the lower flange 25 d of the laminated C-shaped liner 25 is inserted through the slit 5 c and the lower flange 25 d is projected to the back side of the car floor support frame 5. At this time, the upper flange 5 b of the car floor support frame 5 is accommodated in the deep groove of the innermost C-shaped liner 25. The upper flange 25u is located above the upper flange 5b of the car floor support frame 5 and is interposed between the intermediate shelves 8b of the car floor frame 8. As shown in FIG. 4 (c), the open ends of the upper flange 25u and the lower flange 25d protruding to the back side of the car floor support frame 5 are struck with a hammer 26 and bent downward to grip the upper flange 5b to form a C shape. The liner 25 is fixed.

上記実施の形態２によっても、かご床支持枠５の上部フランジ５ｂにＣ形はさみ金２５を固着させたので、積載荷重によって防振ゴム７が圧縮されてかご床支持枠５とかご床枠８との間隔が狭められると、Ｃ形はさみ金２５が挟まれて押圧される。このため、積載荷重が防振ゴム７とＣ形はさみ金２５によって分担されて支持される。この荷重分担によって防振ゴム７の圧縮変形が制限される。
特に、Ｃ形はさみ金２５からかご床枠８の中間棚部８ｂの下面までの距離を防振ゴム７の許容たわみである寸法δ１に設定したので、防振ゴム７が許容たわみを越えて圧縮変形することはない。
しかも、Ｃ形はさみ金２５の取付けは、金槌２６で打ち付けて上部フランジ５ｂに固着させる、という簡単な作業であるので、エレベータの据付け現場の実状に応じて防振ゴム７の圧縮変形を容易に制限することができる。
また、Ｃ形はさみ金２５を平板状にしたので、広い面積で荷重を受けることになる。このため、Ｃ形はさみ金２５が積載荷重を分担しても応力集中は生じない。 Also according to the second embodiment, since the C-shaped liner 25 is fixed to the upper flange 5b of the car floor support frame 5, the vibration isolating rubber 7 is compressed by the loaded load, and the car floor support frame 5 and the car floor frame 8 Is narrowed, the C-shaped liner 25 is sandwiched and pressed. For this reason, the loaded load is shared and supported by the anti-vibration rubber 7 and the C-shaped liner 25. This load sharing restricts the compression deformation of the anti-vibration rubber 7.
In particular, since the distance from the C-shaped liner 25 to the lower surface of the intermediate shelf portion 8b of the car floor frame 8 is set to the dimension δ1 which is the allowable deflection of the anti-vibration rubber 7, the anti-vibration rubber 7 is compressed beyond the allowable deflection. There is no deformation.
In addition, since the C-shaped liner 25 is attached by a hammer 26 and fixed to the upper flange 5b, it is easy to compress and deform the anti-vibration rubber 7 according to the actual situation of the elevator installation site. Can be limited.
In addition, since the C-shaped liner 25 has a flat plate shape, the load is received over a wide area. For this reason, even if the C-shaped liner 25 shares the load, no stress concentration occurs.

なお、上記実施の形態１では、磁気はさみ金１７の取付けは、磁力によってかご床支持枠５に吸着させて積み重ねるようにしたが、磁力に加えて接着剤を併用してもよい。これによって更に強固に固定することができる。
また、上記実施の形態１では、はさみ金を磁気はさみ金１７としたが、これに替えて磁気を帯びない非磁性材を接着剤で接着して積層して、かご床支持枠とかご床との間に介在させてもよい。これによって材料の入手が容易になる。
更に、上記実施の形態１及び２では、防振手段として防振ゴム７を使用するものとしたが、広く弾性体であればよく、例えば、ばねであってもよい。
更にまた、上記実施の形態１及び２では、はさみ金である磁気はさみ金１７及びＣ形はさみ金２５を、いずれもかご床支持枠５に取り付けるものとしたが、かご床１１側に取り付けてもよい。 In the first embodiment, the magnetic liner 17 is attached to the car floor support frame 5 by magnetic force and stacked. However, an adhesive may be used in addition to the magnetic force. Thereby, it can fix still more firmly.
Further, in the first embodiment, the magnetic liner 17 is used as the liner, but instead of this, a non-magnetic material that does not have magnetism is bonded and laminated with an adhesive, and the car floor support frame and the car floor You may interpose between.
