According to the car of the present invention, when a worker or the like opens the ceiling shield plate, the ceiling shield plate is prevented from acceleratingly protruding into the car due to its own weight, and passengers and work in the car It is possible to improve the safety of the person. Issues, configurations, and effects other than those described above will be clarified by the explanation of the following examples.
以下、本発明の実施例を図面に基づいて説明する。
Hereinafter, examples of the present invention will be described with reference to the drawings.
図１から図３を用いて、本発明の実施例１に係る、エレベータ装置の乗りかごを説明する。
The car of the elevator device according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 3.
図１は、本実施例の乗りかご１の天丼側に設けた遮蔽板の閉状態を示す断面図である。ここに示すように、乗りかご１の天井２の下面には、複数の照明２ａとそれらを囲む取付枠３が固定されており、この取付枠３の下部開口が二枚の透光性の天井遮蔽板４，５で覆われている。また、天井２の略中央部には、天井救出口を塞ぐ救出口遮蔽板６が、連結部６ａによって開閉可能に連結されている。
FIG. 1 is a cross-sectional view showing a closed state of a shielding plate provided on the top bowl side of the car 1 of this embodiment. As shown here, a plurality of lights 2a and a mounting frame 3 surrounding them are fixed to the lower surface of the ceiling 2 of the car 1, and the lower opening of the mounting frame 3 is two translucent ceilings. It is covered with shielding plates 4 and 5. Further, a rescue outlet shielding plate 6 that closes the ceiling rescue outlet is connected to the substantially central portion of the ceiling 2 so as to be openable and closable by a connecting portion 6a.
このような構成の本実施例の乗りかご１では、エレベータ装置の運行時には閉状態の天井遮蔽板４，５を必要に応じて開状態にすることで、照明２ａの交換や、天井救出口を利用した人の出入を可能にする。以下、天井遮蔽板４，５を開状態にするために用いる構造を中心に、乗りかご１の詳細を説明する。
In the car 1 of the present embodiment having such a configuration, the ceiling shield plates 4 and 5 in the closed state are opened as necessary when the elevator device is in operation, so that the lighting 2a can be replaced and the ceiling rescue outlet can be replaced. Allows users to enter and exit. Hereinafter, the details of the car 1 will be described with a focus on the structure used to open the ceiling shielding plates 4 and 5.
図１に示すように、天井遮蔽板４，５の中央側端部は、連結部４ａによって互いに回転可能に連結されている。一方の天井遮蔽板４の外側端部には、取付枠３の一対の側面（図１の例では、紙面手前側と紙面奥側の二側面）に設けた一対のガイド３ａ内を、回転しながら移動する一対のローラ４ｂが設けられている。他方の天井遮蔽板５の外側端部には、天井遮蔽板５と取付枠３の外側端部を回転可能に連結する連結部５ａが設けられている。なお、ここでは、天井遮蔽板４の外側端部にローラ４ｂを設けた構成を例示したが、ローラ４ｂに代え、ガイド３ａ内を滑りながら移動するピン等の摺動体を設けても良い。
As shown in FIG. 1, the central end portions of the ceiling shielding plates 4 and 5 are rotatably connected to each other by the connecting portion 4a. At the outer end of one ceiling shield plate 4, a pair of guides 3a provided on a pair of side surfaces of the mounting frame 3 (two side surfaces on the front side and the back side of the paper surface in the example of FIG. 1) are rotated. A pair of rollers 4b that move while being provided are provided. The outer end of the other ceiling shield 5 is provided with a connecting portion 5a that rotatably connects the ceiling shield 5 and the outer end of the mounting frame 3. Although the configuration in which the roller 4b is provided at the outer end of the ceiling shielding plate 4 is illustrated here, a sliding body such as a pin that moves while sliding in the guide 3a may be provided instead of the roller 4b.
また、天井遮蔽板５の上面の中央側端部には、可動式のロック体５ｂが取り付けられており、このロック体５ｂが取付枠３の側面から突出する固定部３ｃと係合している。このロック体５ｂが係合状態のときは、天井遮蔽板４，５が閉状態に保持されている。しかし、作業者がロック体５ｂを操作し係合を解くと、天井遮蔽板４，５の自重により、ローラ４ｂがガイド３ａに案内されて図１の紙面左方向へ移動し、天井遮蔽板４，５の開動作が開始される。
A movable lock body 5b is attached to the central end of the upper surface of the ceiling shield plate 5, and the lock body 5b is engaged with a fixing portion 3c protruding from the side surface of the mounting frame 3. .. When the lock body 5b is in the engaged state, the ceiling shielding plates 4 and 5 are held in the closed state. However, when the operator operates the lock body 5b to disengage the engagement, the rollers 4b are guided by the guide 3a due to the weight of the ceiling shielding plates 4 and 5 and move to the left on the paper surface of FIG. 1, and the ceiling shielding plate 4 , 5 opening operation is started.
ここで、本実施例のガイド３ａには、天井遮蔽板４，５の開動作の初期に、ローラ４ｂの移動を一時的に制限するための、上り坂の勾配とした制限部３ｂが形成されている。なお、制限部３ｂの前後には、制限部３ｂよりも穏やか移動面が設けられているので、制限部３ｂの前後では、ローラ４ｂの移動が制限されることがない。
Here, in the guide 3a of the present embodiment, a limiting portion 3b having an uphill slope is formed to temporarily limit the movement of the rollers 4b at the initial stage of the opening operation of the ceiling shielding plates 4 and 5. ing. Since a gentler moving surface than the limiting portion 3b is provided before and after the limiting portion 3b, the movement of the roller 4b is not restricted before and after the limiting portion 3b.
このような構成の乗りかご１によれば、作業者がロック体５ｂの係合を解くとローラ４ｂがガイド３ａに沿って図示の右側から左側に移動するとともに、天井遮蔽板４，５を連結する連結部４ａが下方に移動する。この結果、天井遮蔽板４，５は連結部４ａを中心にして折り畳まれ、下方に凸となるＶ字状態となって開放される。
According to the car 1 having such a configuration, when the operator disengages the lock body 5b, the roller 4b moves from the right side to the left side in the figure along the guide 3a, and the ceiling shielding plates 4 and 5 are connected. The connecting portion 4a to be connected moves downward. As a result, the ceiling shielding plates 4 and 5 are folded around the connecting portion 4a and opened in a V-shaped state that is convex downward.
このため、特許文献１のように一枚構成の天井遮蔽板を使用した場合に比べ、開状態であっても天井遮蔽板が乗りかご１内に大きく突出することがなく、作業者や乗客が天井遮蔽板に衝突する可能性を抑制することができる。
Therefore, as compared with the case of using a single-sheet ceiling shielding plate as in Patent Document 1, the ceiling shielding plate does not protrude significantly into the car 1 even in the open state, and workers and passengers can use it. The possibility of collision with the ceiling shielding plate can be suppressed.
また、二枚の天井遮蔽板を使用する態様として、各天井遮蔽板の外側端部を可回転的に支持した観音開き方式とすることで、開状態時の各天井遮蔽板の突出寸法を小さくすることもできるが、この方式では、開放した二枚の天井遮蔽板が自重により自由落下で加速度的に乗りかご１内に倒れこんでくるため、乗りかご１内の乗客や作業者が天井遮蔽板を避けることができず、天井遮蔽板に当たる恐れもあった。
In addition, as a mode in which two ceiling shield plates are used, the protruding dimension of each ceiling shield plate in the open state is reduced by adopting a Kannon opening method in which the outer end of each ceiling shield plate is rotatably supported. However, in this method, the two open ceiling shields fall freely into the car 1 due to their own weight, so that passengers and workers in the car 1 can fall into the ceiling shields. Was unavoidable, and there was a risk of hitting the ceiling shield.
これに対し、図１に示した本実施例の構成では、ガイド３ａの制限部３ｂと天井遮蔽板４のローラ４ｂの相互作用により、開動作初期の天井遮蔽板の落下速度が抑制されるだけでなく、開動作初期の天井遮蔽板の落下量も制限されるため、観音開き方式のように二枚の天井遮蔽板が加速度的に乗りかご１内に突出してくることもなくなり、乗客や作業者が開動作中の天井遮蔽板に当たる可能性も極めて低くなる。この点については、図２、図３を用いて、さらに詳細に説明する。
＜天丼遮蔽板の開動作初期状態＞
図２は、乗りかご１の天丼遮蔽板の開動作初期状態を示す断面図である。 On the other hand, in the configuration of the present embodiment shown in FIG. 1, the falling speed of the ceiling shielding plate at the initial stage of opening operation is only suppressed by the interaction between thelimiting portion 3b of the guide 3a and the roller 4b of the ceiling shielding plate 4. In addition, since the amount of fall of the ceiling shield plate at the initial stage of opening operation is also limited, the two ceiling shield plates do not accelerately protrude into the car 1 as in the double door method, and passengers and workers do not. Is extremely unlikely to hit the ceiling shield during open operation. This point will be described in more detail with reference to FIGS. 2 and 3.
<Initial state of opening operation of the bowl shield plate>
FIG. 2 is a cross-sectional view showing an initial state of the opening operation of the bowl shield plate of the car 1.

図２は、乗りかご１の天丼遮蔽板の開動作初期状態を示す断面図である。 On the other hand, in the configuration of the present embodiment shown in FIG. 1, the falling speed of the ceiling shielding plate at the initial stage of opening operation is only suppressed by the interaction between the
<Initial state of opening operation of the bowl shield plate>
FIG. 2 is a cross-sectional view showing an initial state of the opening operation of the bowl shield plate of the car 1.
本実施例のガイド３ａには、天井遮蔽板４側の端部に平坦な移動面が設けられている。このため、作業者がロック体５ｂの係合を解いた直後は、天井遮蔽板４、５の自重により、ローラ４ｂはガイド３ａの端部の平坦な移動面を、滑らかに移動開始する。しかし、ガイド３ａの途中には上り坂の勾配とした制限部３ｂが形成されているため、開動作開始直後で速度の比較的遅いローラ４ｂは、制限部３ｂを乗り越えることができず、制限部３ｂの手前で一旦停止する。
The guide 3a of this embodiment is provided with a flat moving surface at the end on the ceiling shielding plate 4 side. Therefore, immediately after the operator disengages the lock body 5b, the roller 4b smoothly starts moving on the flat moving surface at the end of the guide 3a due to the weight of the ceiling shielding plates 4 and 5. However, since the limiting portion 3b having an uphill slope is formed in the middle of the guide 3a, the roller 4b having a relatively slow speed immediately after the start of the opening operation cannot get over the limiting portion 3b, and the limiting portion 3b cannot be overcome. It stops just before 3b.
この一旦停止状態となったとき、ロック体５ｂの係合を解いた作業者は、天井遮蔽板４，５を更に開く必要があるかや、天井遮蔽板４，５の可動範囲に乗客や他の作業者がいないかを判断する。例えば、天井遮蔽板４側の照明２ａだけを交換するのであれば、天井遮蔽板を半開き状態とすれば十分であるので、それ以上の開動作は不要と判断することもできるし、乗りかご１内に他の作業者や乗客がいる場合は、更なる開動作を行う前に、天井遮蔽板の突出を注意喚起することもできる。
When the lock body 5b is temporarily stopped, the worker who disengages the lock body 5b needs to open the ceiling shield plates 4 and 5 further, or passengers and others within the movable range of the ceiling shield plates 4 and 5. Determine if there are any workers. For example, if only the lighting 2a on the ceiling shielding plate 4 side is to be replaced, it is sufficient to open the ceiling shielding plate in a half-open state, so that it can be determined that further opening operation is unnecessary, and the car 1 If there are other workers or passengers inside, it is possible to call attention to the protrusion of the ceiling shield before performing further opening operations.
そして、天井遮蔽板４，５をさらに開く必要があると判断した場合は、作業者は、天井遮蔽板４をさらに左方向にスライドさせるか、連結部４ａをさらに下方に下げる。すると、ローラ４ｂが上り勾配の制限部３ｂを比較的簡単に乗り越え、開動作を継続することできる。
＜天丼遮蔽板の開動作終期状態＞
図３は、乗りかご１の天丼遮蔽の開動作終期状態を示す断面図である。 Then, when it is determined that the ceiling shield plates 4 and 5 need to be opened further, the operator slides the ceiling shield plate 4 further to the left or lowers the connecting portion 4a further downward. Then, the roller 4b can overcome the uphill limiting portion 3b relatively easily and continue the opening operation.

<End of open operation of Tendon shield plate>
FIG. 3 is a cross-sectional view showing the final state of the opening operation of the bowl shield of the car 1.
作業者が天井遮蔽板４等を操作して、ローラ４ｂが上り勾配の制限部３ｂを乗り越えると、ローラ４ｂはガイド３ａの穏やかな下り勾配部分を左方向に移動することとなる。この結果、図３に示すように、天井遮蔽板５の連結部５ａにローラ４ｂが接近し、天井遮蔽板４，５が連結部４ａを中心にしてほぼ二つ折りにされたＶ字状態となる。このため、取付枠３の下部開口は、天井遮蔽板４，５によって覆われた図１の閉状態から、大きく開かれた図３の開状態になる。図３の開状態となれば、作業者は、天井遮蔽板４側の照明２ａだけでなく、天井遮蔽板５側の照明２ａも容易に交換することができる。
When the operator operates the ceiling shield plate 4 or the like and the roller 4b gets over the limiting portion 3b of the uphill slope, the roller 4b moves to the left on the gentle downhill slope portion of the guide 3a. As a result, as shown in FIG. 3, the roller 4b approaches the connecting portion 5a of the ceiling shielding plate 5, and the ceiling shielding plates 4 and 5 are substantially folded in half around the connecting portion 4a in a V-shape. .. Therefore, the lower opening of the mounting frame 3 changes from the closed state of FIG. 1 covered by the ceiling shielding plates 4 and 5 to the wide open state of FIG. When the state of FIG. 3 is opened, the operator can easily replace not only the lighting 2a on the ceiling shielding plate 4 side but also the lighting 2a on the ceiling shielding plate 5 side.
図３に示す開状態は、乗りかご１内の乗客をかご上から救出する救出経路を確保するときに特に効果的である。図３を兼用して説明すると、かご上の作業者が救出口遮蔽板６を図３に示すように開いた後、かご上からロック体５ｂの係合を手動で解く。このとき、かご上の作業者からは、乗りかご１内の状況や乗客を確認できないが、ローラ４ｂの移動がガイド３ａの制限部３ｂで一時的に制限されるため、天井遮蔽板４，５は、乗りかご１内にわずかに突出した図２に示す状態で一旦停止する。そこで、かご上の作業者はまず、乗りかご１内の乗客に声がけ等して、乗客を安全な位置（図１から図３の例では、天井遮蔽板４，５の可動範囲外となる、乗りかご１の右側等）に誘導する。
The open state shown in FIG. 3 is particularly effective when securing a rescue route for rescuing passengers in the car 1 from above the car. Explaining with reference to FIG. 3, after the operator on the car opens the rescue exit shielding plate 6 as shown in FIG. 3, the lock body 5b is manually disengaged from above the car. At this time, the operator on the car cannot confirm the situation in the car 1 and the passengers, but since the movement of the roller 4b is temporarily restricted by the limiting portion 3b of the guide 3a, the ceiling shielding plates 4 and 5 Temporarily stops in the state shown in FIG. 2 slightly protruding into the car 1. Therefore, the worker on the car first calls out to the passengers in the car 1 and puts the passengers in a safe position (in the examples of FIGS. 1 to 3, the ceiling shielding plates 4 and 5 are out of the movable range). , Right side of car 1 etc.).
乗客の安全な位置への移動を確認すると、かご上の作業者は、天井遮蔽板４や連結部４ａを押し下げ、ローラ４ｂに上り勾配の制限部３ｂを乗り越えさせる。ローラ４ｂが上り勾配の制限部３ｂを乗り越えると、ローラ４ｂは穏やかな下り勾配のガイド３ａを進み、最終的に、図３に示すように天井遮蔽板５の連結部５ａにローラ４ｂが接近し、天井遮蔽板４，５が連結部４ａを中心にしてほぼ二つ折りにされたＶ字状態となる。この一連の開動作時に、乗りかご１内の乗客等は、天井遮蔽板４，５の可動範囲を避けた安全な位置にいるので、天井遮蔽板４，５が乗客等に当たることがない。
After confirming that the passengers have moved to a safe position, the worker on the car pushes down the ceiling shield plate 4 and the connecting portion 4a, and causes the roller 4b to overcome the uphill limiting portion 3b. When the roller 4b gets over the limiting portion 3b of the uphill slope, the roller 4b advances on the guide 3a of the gentle downhill slope, and finally the roller 4b approaches the connecting portion 5a of the ceiling shielding plate 5 as shown in FIG. , The ceiling shielding plates 4 and 5 are folded in half around the connecting portion 4a to form a V-shape. During this series of opening operations, the passengers and the like in the car 1 are in a safe position avoiding the movable range of the ceiling shield plates 4 and 5, so that the ceiling shield plates 4 and 5 do not hit the passengers and the like.
以上で説明したように、本実施例の乗りかごによれば、天井遮蔽板を開放する際に、天井遮蔽板が自重により加速度的に乗りかご内に大きく倒れ込んでくることを防止して、乗りかご内の乗客や作業者の安全性の向上を図ることができる。
As described above, according to the car of the present embodiment, when the ceiling shield plate is opened, it is prevented that the ceiling shield plate is acceleratedly collapsed into the car due to its own weight, and the passenger rides. It is possible to improve the safety of passengers and workers in the car.
