Such carts include carts that are generally moved by human power (hereinafter referred to as "general carts") and AGVs (Automatic Guided Vehicles).

一般台車及びＡＧＶを含む台車のエレベーターのかご内への出入りのために、エレベーターのかご内と階層床つまりエレベーターが設けられた躯体の床面との間に渡し板をかけることが行われている。例えば特許文献１は、前面の荷物などを積み下ろしするための開口部に扉を有するエレベーターにおいて、自動スライド機構で、エレベーターと躯体の床面との空隙部を受け渡しする踏み板を動かすことを開示する。この自動スライド機構は、エレベーターの前面に沿って鉛直方向に設けられたガイドレールと、このガイドレールに沿ってガイドローラを介して設けられた支持棒と、この支持棒に設けられたエレベーターの開口部の幅と略等しい長さのアングルと、ガイドレールとアングルとに取付けられた踏み板昇降用シリンダーと、このアングルに設けられた踏み板取付用の蝶番と、踏み板を起倒させるためアングルに設けられた踏み板作動用シリンダーとからなっていて、踏み板は前述の蝶番に取付けられている。目的階にエレベーターを停止させると、自動スライド機構は、踏み板昇降用シリンダーを伸ばして踏み板を躯体の床面に合わせた位置に上昇させ、次に踏み板作動用シリンダーを収縮させ踏み板を倒して躯体の床面に接地させる。これにより、扉を開いて積み下ろしを行うことを可能にする。 In order to allow carriages including general carriages and AGVs to enter and exit the elevator car, a bridge board is placed between the inside of the elevator car and the upper floor, that is, the floor surface of the frame on which the elevator is installed. . For example, Patent Literature 1 discloses that in an elevator having a door at an opening for loading and unloading luggage on the front, an automatic slide mechanism moves a footboard that transfers a gap between the elevator and the floor surface of the frame. This automatic slide mechanism consists of a guide rail provided vertically along the front surface of the elevator, a support bar provided along the guide rail via a guide roller, and an elevator opening provided in the support bar. An angle with a length approximately equal to the width of the part, a tread lift cylinder attached to the guide rail and the angle, a tread plate mounting hinge provided on this angle, and a tread plate provided on the angle for raising and lowering the tread plate. and a treadplate actuating cylinder, the treadplate being attached to the aforementioned hinge. When the elevator is stopped at the destination floor, the automatic slide mechanism extends the tread lift cylinder to raise the tread to a position aligned with the floor surface of the frame, then retracts the tread plate operation cylinder to knock down the tread and lower the frame. Ground it on the floor. This allows the door to be opened for loading and unloading.

特許第３１５１５７５号公報Japanese Patent No. 3151575

上記特許文献１の自動スライド機構は、躯体の床面とエレベーターのかごの床面（以下、単に「床面」と称し得る。）が一致したことをセンサーで検出したとき、作動可能なものであり、更に踏み板を接地させるために２つのシリンダーを所定の順序で作動させることが必要である。 The automatic slide mechanism of Patent Document 1 is operable when a sensor detects that the floor surface of the building frame and the floor surface of the elevator car (hereinafter simply referred to as "floor surface") are aligned.

As shown in FIG. An elastic member 38 may be provided in the middle of the wire 40 . The arrangement and number of locking members 22 are not limited to this.

弾性部材２０が設けられて係止部材２２で連結された第１板部材１６及び第２板部材１８の各表面には、図３及び図４に示すように、化粧板４２、４４が設けられている。化粧板４２は第１板部材１６にリベット等の接合手段により固定され、化粧板４４は第２板部材１８にリベット等の接合手段により固定されている。化粧板４２、４４を設けることで、図３に示すように、渡し板部材１０の表面を、エレベーター１４の床面１４ｓと実質的に同じ高さに位置付けて延ばすことが容易に可能になる。そして、化粧板４２、４４を設けることで、第１板部材１６の表面及び第２板部材１８の表面が滑らかになり、ＡＧＶなどの台車のより滑らかな走行が可能になる。化粧板４２、４４は、第１板部材１６と第２板部材１８とのいずれか一方にのみ、例えば第１板部材１６にのみ設けられてもよい。なお、図４では、理解を容易にするため化粧板４２、４４は離して設けられているが、それらの間の隙間は狭いほどよい。 As shown in FIGS. 3 and 4, decorative plates 42 and 44 are provided on the respective surfaces of the first plate member 16 and the second plate member 18, which are provided with the elastic member 20 and connected by the locking member 22. ing. The decorative plate 42 is fixed to the first plate member 16 by joining means such as rivets, and the decorative plate 44 is fixed to the second plate member 18 by joining means such as rivets. By providing the decorative plates 42, 44, as shown in FIG. 3, the surface of the bridge plate member 10 can be easily positioned and extended at substantially the same height as the floor surface 14s of the elevator 14. By providing the decorative plates 42 and 44, the surface of the first plate member 16 and the surface of the second plate member 18 are smoothed, so that the truck such as the AGV can run more smoothly. The decorative plates 42 and 44 may be provided only on either one of the first plate member 16 and the second plate member 18 , for example, only on the first plate member 16 . In FIG. 4, the decorative plates 42 and 44 are separated from each other for easy understanding, but the narrower the gap between them, the better.

図３には、躯体の目的階の床面Ｆｓにかかるように延びる展開状態の渡し板部材１０が示され、開いた状態の内扉２８の下側部分２８ｄの上端側が表されている。内扉２８の下側部分２８ｄが上下方向の矢印Ａ２に沿って上昇することで、内扉２８の下側部分２８ｄは上記第１板部材１６に直接的に作用し、よって渡し板部材１０を図２及び図５に示すように立たせることができる。したがって、第１板部材１６は所定強度以上の強度を有するとよく、ここでは鉄鋼材料製である。これに対して、第２板部材１８は第１板部材１６の先端３２側に設けられ、回動軸３１周りに大きく動かされる。そこで、第２板部材１８は軽量化を目的としてここではＭｇ合金製である。なお、第１板部材１６は鉄鋼材料以外の金属材料などの種々の材料で作製されてもよく、第２板部材１８もＭｇ合金以外の金属材料などの種々の材料で作製されてもよい。 FIG. 3 shows the spread plate member 10 extending over the floor surface Fs of the target floor of the frame, and shows the upper end side of the lower portion 28d of the inner door 28 in the open state. As the lower portion 28d of the inner door 28 rises along the vertical arrow A2, the lower portion 28d of the inner door 28 directly acts on the first plate member 16, thereby moving the bridge plate member 10. It can stand up as shown in FIGS. Therefore, the first plate member 16 preferably has a strength equal to or greater than a predetermined strength, and is made of steel material here. On the other hand, the second plate member 18 is provided on the tip 32 side of the first plate member 16 and is largely moved around the rotary shaft 31 . Therefore, the second plate member 18 is made of Mg alloy here for the purpose of weight reduction. The first plate member 16 may be made of various materials such as metal materials other than steel materials, and the second plate member 18 may also be made of various materials such as metal materials other than Mg alloys.

また、図６及び図７に示すように、渡し板部材１０が躯体の目的階の床面Ｆｓにかかっているとき、第１板部材１６の先端３２は床面Ｆｓ上にまで直接的に至るとよい。これにより、エレベーター１４のかご１２と目的階の床面Ｆｓとの間の隙間Ｇを、より高強度の第１板部材１６で確実に渡すことができる。なお、これは、第１板部材１６の先端３２が床面Ｆｓ上に到達し得ないことを排除するものではない。 Further, as shown in FIGS. 6 and 7, when the bridge plate member 10 is placed on the floor surface Fs of the target floor of the skeleton, the tip 32 of the first plate member 16 directly reaches the floor surface Fs. Good. Thereby, the gap G between the car 12 of the elevator 14 and the floor surface Fs of the destination floor can be reliably bridged by the first plate member 16 having higher strength. Note that this does not exclude the fact that the tip 32 of the first plate member 16 cannot reach the floor surface Fs.

なお、ＡＧＶは概して視野角の狭いセンサーを有し、自律走行する。そのセンサーを用いてのＡＧＶの自律走行で渡し板部材１０上を走行可能にするために、渡し板部材１０が、図６及び図７に示す使用状態のとき、最大で３０ｍｍ／１０００ｍｍ（１ｍで３ｃｍの傾斜）内の傾斜（傾き）を好適に有し続けるように、ここでは第１板部材１６の厚さ、第２板部材１８の厚さなどは設計されている。 AGV generally has a sensor with a narrow viewing angle and travels autonomously. In order to allow the AGV to travel on the bridge member 10 autonomously using the sensor, the bridge member 10 has a maximum of 30 mm/1000 mm (at 1 m) in the state of use shown in FIGS. Here, the thickness of the first plate member 16, the thickness of the second plate member 18, etc. are designed so as to preferably continue to have an inclination (inclination) within the inclination of 3 cm.

上記構成を有する渡し板部材１０の動きなどについて、図２、図５、図６及び図７に基づいて説明する。なお、図５、図６及び図７において外扉２６は省略する。 The movement of the bridge plate member 10 having the above configuration will be described with reference to FIGS. 2, 5, 6 and 7. FIG. 5, 6 and 7, the outer door 26 is omitted.

エレベーター１４では、内扉２８が閉じられているとき、図２及び図５に示すように、渡し板部材１０は内扉２８に、特にそれの下側部分２８ｄに寄りかかって立った状態にある。この状態で、エレベーター１４が目的階に到着して外扉２６が開き、内扉２８が開くと、下側部分２８ｄが下方に下がり（矢印Ａ２参照）、渡し板部材１０は第１板部材１６の基端３０の回動軸３１周りにその自重で回転し、目的階の床面Ｆｓにかかることができる。 In the elevator 14, when the inner door 28 is closed, the bridge member 10 stands against the inner door 28, particularly the lower portion 28d thereof, as shown in FIGS. . In this state, when the elevator 14 arrives at the destination floor, the outer door 26 is opened, and the inner door 28 is opened, the lower part 28d is lowered (see arrow A2), and the bridge plate member 10 moves from the first plate member 16 It rotates around the pivot shaft 31 at the base end 30 of the floor by its own weight, and can be applied to the floor surface Fs of the destination floor.

渡し板部材１０は第１板部材１６と第２板部材１８とが板バネ２０ｓと係止部材２２とで連結されていてその継ぎ目は柔軟に曲がることができる。したがって、図６に示すようにエレベーター１４の床面１４ｓに対して床面Ｆｓが適した高さ位置つまりほぼ同じ高さにある場合だけでなく、図７に示すようにエレベーター１４の床面１４ｓに対して目的階の床面Ｆｓが大きく下方にずれていたとしても、渡し板部材１０は床面Ｆｓにかかり、エレベーター１４の床面１４ｓと床面Ｆｓとを滑らかにつなぐことができる。したがって、目的階の床面Ｆｓを走行するＡＧＶなどの台車はエレベーター１４内に容易に入ることができ、またエレベーター１４内の台車は目的階の床面Ｆｓに容易に移動することができる。なお、この渡し板部材１０による床面１４ｓ、Ｆｓ間のつながりは、仮にエレベーター１４の床面１４ｓよりも目的階の床面Ｆｓが上方にずれたとしても、成立し得る。 In the bridge member 10, a first plate member 16 and a second plate member 18 are connected by a plate spring 20s and a locking member 22, and the joint can be flexibly bent. Therefore, as shown in FIG. 6, the floor surface Fs of the elevator 14 and the floor surface 14s of the elevator 14 are at a suitable height, that is, at approximately the same height. Even if the floor surface Fs of the destination floor deviates greatly downward, the bridge plate member 10 is applied to the floor surface Fs, and the floor surface 14s of the elevator 14 and the floor surface Fs can be smoothly connected. Therefore, a truck such as an AGV running on the floor surface Fs of the destination floor can easily enter the elevator 14, and the truck in the elevator 14 can easily move to the floor surface Fs of the destination floor. The connection between the floor surfaces 14s and Fs by the bridge member 10 can be established even if the floor surface Fs of the destination floor is shifted upward from the floor surface 14s of the elevator 14.

そして、エレベーター１４の開口部２４つまり内扉２８及び外扉２６が閉じるとき、内扉２８の下側部分２８ｄの上昇に伴って、第１板部材１６は回動軸３１で立つ方向（上下方向の上側）に動かされ、渡し板部材１０は内扉２８内に収容される。これにより、渡し板部材１０は図２及び図５に示す状態になる。 Then, when the opening 24 of the elevator 14, that is, the inner door 28 and the outer door 26 are closed, the first plate member 16 moves in the upright direction (vertical direction) along the rotation shaft 31 as the lower portion 28d of the inner door 28 rises. ), and the bridge plate member 10 is accommodated in the inner door 28 . As a result, the bridge plate member 10 is brought into the state shown in FIGS.

以上述べたように渡し板部材１０は簡易な構成を有し簡易な構成で動かされ、内扉２８の開閉に伴って、図２及び図５に示す収容状態と、図６及び図７に示す展開状態（使用状態）とになることができる。よって、渡し板部材１０によれば、目的階にエレベーターが到着したときに、内扉２８が開くことで、渡し板部材１０がその自重で自動的に躯体の床面Ｆｓに倒れかかることができ、エレベーターの床面と躯体の目的階の床面とを好適につなぐことが可能になる。特に、その際に、板バネ２０ｓと係止部材２２とにより第１板部材１６と第２板部材１８との間の相対的な関係が柔軟に変化することができるので、渡し板部材１０と躯体の床面との間の段差をより小さくすることができ、よってエレベーターの床面と躯体の目的階の床面とを台車がより滑らかに走行することが可能になる。 As described above, the bridge plate member 10 has a simple structure and is moved by a simple structure. It can be in a deployed state (used state). Therefore, according to the bridge member 10, when the elevator arrives at the destination floor, the inner door 28 is opened, so that the bridge member 10 can automatically fall on the floor surface Fs of the frame by its own weight. , the floor surface of the elevator and the floor surface of the target floor of the skeleton can be preferably connected. In particular, at that time, the relative relationship between the first plate member 16 and the second plate member 18 can be flexibly changed by the plate spring 20s and the locking member 22, so that the bridge plate member 10 and the A step between the floor surface of the frame and the floor surface can be made smaller, so that the truck can run more smoothly between the floor surface of the elevator and the floor surface of the target floor of the frame.

なお、上記エレベーター１４では、内扉２８が予め設けられていた。しかし、本開示の渡し板部材が適用されるエレベーターが内扉２８の下側部分２８ｄなどの下開きの扉部材を備えない場合、内扉２８も渡し板部材１０とともに設けられるとよい。 The elevator 14 is provided with an inner door 28 in advance. However, if the elevator to which the bridge member of the present disclosure is applied does not include a downward-opening door member such as the lower portion 28d of the inner door 28, the inner door 28 may also be provided together with the bridge member 10.

なお、渡し板部材１０では、第１板部材１６の先端３０側に第２板部材１８を設けたが、その第２板部材の先端側に更なる板部材（第３板部材）を設けてもよい。この場合、第２板部材と第３板部材との連結は、第１板部材と第２板部材との連結のように、弾性部材２０と係止部材２２とを用いて行われるとよい。 In the bridge member 10, the second plate member 18 is provided on the tip 30 side of the first plate member 16, but a further plate member (third plate member) is provided on the tip side of the second plate member. good too. In this case, the connection between the second plate member and the third plate member is preferably performed using the elastic member 20 and the locking member 22, like the connection between the first plate member and the second plate member.
