本考案はエレベータのかごの荷重を弾性支持装
置の変位によつて検出するエレベータ用荷重検出
装置の改良に関するものである。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an improvement of an elevator load detection device that detects the load of an elevator car by the displacement of an elastic support device.

As shown in Fig. 1, the structure of the elevator is such that a hoisting rope 3 is wound around a sheep 2 driven by a hoisting motor 1, a car frame 4 is connected to one end of this hoisting rope 3, and a car 6 is made of elastic material. It is supported by the car frame 4 by the body 5. Further, a counterweight 7 is coupled to the other end of the hoisting rope 3.

される。 The elastic body 5 absorbs vibrations transmitted from the outside through the hoisting rope 3 and the car frame 4, and
It is provided to improve the riding comfort inside. Since the deflection of the elastic body 6 changes depending on the increase or decrease of the load caused by the passengers in the car 6, a device (not shown) is provided to detect changes in this deflection. The output of this detection device is used for various purposes.

決するためには次のような対策方法の原理が一般
によく知られている。 In this case, it is required that the load versus deflection characteristics (hereinafter referred to as spring characteristics) of the elastic body 5 are always constant. Conventionally, vibration isolating rubber with good vibration damping properties has generally been used for this elastic body. However, since this anti-vibration rubber is an elastic body with non-linear spring characteristics, the above-mentioned characteristics when the load of the car 6 gradually increases and the above-mentioned characteristics when the load gradually decreases do not match, and it has a hysteresis phenomenon and a seasonal phenomenon. There were various problems such as the above-mentioned characteristics being different due to changes. For this reason, the deflection detection device needs to be adjusted from time to time.
Maintenance work was time-consuming. In order to solve this problem, the principle of the following countermeasure method is generally well known.

には次のような問題点がある。 That is, as shown in Fig. 2, the car frame 4 is
A car 6 for this purpose is arranged, and this car 6 is connected in series with a first elastic body 8 having vibration damping characteristics and a second elastic body 9 with linear spring characteristics of load versus displacement. supported on the car frame 4 by something,
It is known that it is sufficient to provide a device that detects the displacement of the second elastic body due to a change in the load inside the car 6. However, there are the following problems in embodying the structure using this method.

とである。 That is, in the above method, the first elastic body and the second
Since the elastic bodies are connected in series, the total length of the connected elastic bodies becomes long and cannot be accommodated within the conventional gap between the car frame and the car. To increase this distance,
This would require a fairly drastic modification, either by lengthening the car frame or shortening the length of the car.

The purpose of this invention is to address the above-mentioned problems, and to make it possible to install conventional car frames and cars without increasing their size.
It is an object of the present invention to provide a structure of a load detection device for an elevator that allows linear spring characteristics to be easily obtained.

The present invention provides a structure in which a first elastic body and a second elastic body are connected in series between a car frame and a car.
A vibration isolating rubber is used as the elastic body, and a leaf spring is used as the second elastic body, and the vibration isolating rubber is connected to the plate surface of the leaf spring, and the displacement direction of the leaf spring is determined by the displacement of the vibration isolating rubber. It has a structure that matches the direction.
以下、第３図に基づいて、本考案の一実施例を
説明する。
Hereinafter, one embodiment of the present invention will be described based on FIG.
図中、１１はばね特性が線形なる金属の板ばね
で、両端がかご枠４の突起部に支持されている。
この板ばね１１の長手方向の中間の板面には防振
ゴム１０の一端が連結されており、上記防振ゴム
１０の別端がかご６に連結されている。勿論、上

り、上記板ばね１１も上記防振ゴム１０の変位方
向と同じ方向に変位するようにしている。そして
既述のたわみ検出装置は、板ばね１１のたわみを
検出させるように構成されている。 In the figure, reference numeral 11 denotes a metal leaf spring with linear spring characteristics, and both ends are supported by protrusions of the car frame 4.
One end of a vibration isolating rubber 10 is connected to the intermediate plate surface of the leaf spring 11 in the longitudinal direction, and the other end of the vibration isolating rubber 10 is connected to the car 6. Of course, the vibration isolating rubber 10 is displaced in the vertical direction, and the leaf spring 11 is also displaced in the same direction as the vibration isolating rubber 10. The deflection detection device described above is configured to detect the deflection of the leaf spring 11.
このように、防振ゴム１０と板ばね１１を連結
して弾性支持装置を構成したもので、かご枠およ
びかごの寸法を大形化することなく、線形のばね
特性が得られる荷重検出装置を得ることができ
る。 In this way, an elastic support device is constructed by connecting the vibration isolating rubber 10 and the leaf spring 11, and a load detection device that can obtain linear spring characteristics without increasing the dimensions of the car frame and the car can be realized. Obtainable.
即ち、第１の弾性体である防振ゴム１０の圧縮
方向の厚さはかご６へ伝わる振動を防止するに必
要な厚さだけでよいので、荷重検出を行うに必要
な厚さ（たわみ量）ほと厚くする必要はない。一
方、第２の弾性体を板ばね１１としたので、必要
なたわみ量を得るためには板厚や長さを変えれば
良いので、高さ方向に占有する空間は少ない。こ
のため、第１、第２の弾性体を直列につないで配
置したとしても、かご６とかご枠４との間隔を従
来とほとんど変えずに設置することができる。ま
た、荷重対変位のばね特性もゴム材の圧縮でなく
板ばねのたわみとなるので、線形となり、特性が
安定する。 That is, the thickness of the vibration isolating rubber 10, which is the first elastic body, in the compression direction only needs to be the thickness necessary to prevent the vibrations transmitted to the car 6. ) There is no need to make it very thick. On the other hand, since the second elastic body is the leaf spring 11, the plate thickness and length can be changed in order to obtain the required amount of deflection, so that the space occupied in the height direction is small. Therefore, even if the first and second elastic bodies are connected and arranged in series, the distance between the car 6 and the car frame 4 can be installed almost unchanged from that in the conventional case. In addition, the spring characteristics of load versus displacement are linear and stable because they are caused by the deflection of the leaf spring rather than the compression of the rubber material.
また、この場合、防振ゴムと板ばねの接続を逆
にして、板ばねの両端をかごに、防振ゴムをかご
枠に装着しても同様の効果があることは明白であ
る。 Furthermore, in this case, it is clear that the same effect can be obtained even if the connection between the vibration isolating rubber and the leaf spring is reversed, and both ends of the leaf spring are attached to the car and the vibration isolating rubber is attached to the car frame.
次に第４図〜第１１図に基づいて他の実施例を
説明する。 Next, other embodiments will be described based on FIGS. 4 to 11.

で、防振ゴムをさらに小形化できる効果がある。 4 differs from FIG. 3 in that both ends of the leaf spring 11 are connected in series with vibration isolating rubbers 10 and 12. In this embodiment, the load applied to the anti-vibration rubbers 10 and 12 is shared, so there is an effect that the anti-vibration rubbers can be further downsized.
第５図において、第３図と異なるのは、環状形
板ばね１３を用いていることである。 5 differs from FIG. 3 in that an annular leaf spring 13 is used.
この実施例では、板ばねのばね特性の線形範囲

検出を正確に行ない得る効果がある。 In this embodiment, it is possible to widen the linear range of the spring characteristics of the leaf spring, and it is possible to detect the load accurately over a wider range.
第６図において、第３図と異なるのは、Ｕ字形
板ばね１４を用いていることである。 6 differs from FIG. 3 in that a U-shaped leaf spring 14 is used.
この実施例では、先の第５図で示した環状形ば
ねより低コストで製作できる効果がある。 This embodiment has the advantage that it can be manufactured at a lower cost than the annular spring shown in FIG. 5 above.
第７図において、第３図と異なるのは、曲がり
板ばね１５を用いていることである。 The difference between FIG. 7 and FIG. 3 is that a bent leaf spring 15 is used.
この実施例では、かご６とかご枠４の間隔を小
さくでき、かご枠４の長さを短かくできる効果が
ある。 In this embodiment, the distance between the car 6 and the car frame 4 can be reduced, and the length of the car frame 4 can be reduced.

必要がある。 Furthermore, in each of the above embodiments, it is clear that the same effect can be obtained even if the vibration isolating rubber and the leaf spring are connected in series in reverse. In any case, as shown in each of the above-mentioned embodiments, it is necessary to connect the vibration isolating rubber to the plate surface of the leaf spring and to make the displacement directions of the vibration isolating rubber and the leaf spring coincide with each other.
