Description

マンコンベアの床板装置Man conveyor floor board equipment
　この発明は、エスカレータ、動く歩道などの乗降口の床部に設けられているマンコンベアの床板装置に関するものである。 The present invention relates to a floor plate device for a man conveyor provided on a floor of an entrance / exit such as an escalator or a moving walkway.
　従来のマンコンベアの床板装置では、工具が係合される凹部が櫛板のマンホール蓋受け部の幅方向中央部に設けられていた（例えば、特許文献１参照）。 In the conventional floor plate device for a man conveyor, a recess with which a tool is engaged is provided at the center in the width direction of the manhole cover receiving portion of the comb plate (see, for example, Patent Document 1).
　従来のマンコンベアの床板装置において、マンホール蓋を取り付けるには、まず、マンホール蓋を支持梁に支持させて櫛板側に移動させる。このとき、マンホール蓋の自重によりマンホール蓋の一端部が下がり、櫛板のマンホール蓋受け部に突き当たり、マンホール蓋の櫛板側への移動が阻止される。そこで、工具を凹部に差し込み、凹部の底面の角部を支点として着脱工具を回動し、マンホール蓋受け部に近づいたマンホール蓋を持ち上げる。この状態から、マンホール蓋を櫛板側に押し込み、マンホール蓋の先端を櫛板のマンホール蓋受け部に載せる。ついで、工具を引き抜き、マンホール蓋を櫛板側にさらに押し込んで、マンホール蓋を櫛板に取り付けていた。これにより、マンホール蓋は、その先端がマンホール蓋受け部に突き当たることなく、櫛板に取り付けられる。 In order to attach the manhole cover in the conventional man conveyor floor plate apparatus, first, the manhole cover is supported by the support beam and moved to the comb plate side. At this time, one end of the manhole cover is lowered due to the weight of the manhole cover, hits the manhole cover receiving part of the comb plate, and the manhole cover is prevented from moving toward the comb plate. Therefore, the tool is inserted into the recess, and the detachable tool is rotated with the corner portion of the bottom surface of the recess as a fulcrum, and the manhole cover approaching the manhole cover receiving part is lifted. From this state, the manhole cover is pushed into the comb plate, and the tip of the manhole cover is placed on the manhole cover receiving portion of the comb plate. Next, the tool was pulled out and the manhole cover was further pushed into the comb plate side to attach the manhole cover to the comb plate. Thereby, a manhole cover is attached to a comb board, without the front-end | tip striking a manhole cover receiving part.
特許第５０６８５１２号公報Japanese Patent No. 5068512
　従来のマンコンベアの床板装置では、凹部に差し込まれた工具を凹部の底面の角部を支点として回動させて、マンホール蓋の先端をマンホール蓋受け部に載せ、その後工具を引き抜いて、マンホール蓋を櫛板に取り付けていたので、マンホール蓋の取り付け作業が煩雑となるという課題があった。さらに、工具を過度に回動させ、あるいは工具を無理に引き抜いて、工具が櫛板の化粧板を変形させる恐れがあった。櫛板の化粧板が変形すると、櫛板の化粧板とマンホール蓋との表面に段差が生じ、利用者がつまずく原因となる。 In a conventional man conveyor floor plate device, the tool inserted in the recess is rotated with the corner portion of the bottom of the recess as a fulcrum, the tip of the manhole cover is placed on the manhole cover receiving part, and then the tool is pulled out. Was attached to the comb plate, and there was a problem that the work of attaching the manhole cover became complicated. Furthermore, the tool may be excessively rotated or the tool may be forcibly pulled out, causing the tool to deform the decorative plate of the comb plate. When the decorative plate of the comb plate is deformed, a step is generated on the surface of the decorative plate of the comb plate and the manhole cover, which causes the user to stumble.
　この発明は、上記課題を解決するためになされたもので、マンホール蓋のマンホール蓋取付部と櫛板のマンホール蓋受け部との突き当たりを回避する工具を不要とし、マンホール蓋を簡易に取り付けることができるとともに、櫛板用化粧板の変形を防止できるマンコンベアの床板装置を得ることを目的とする。 The present invention has been made to solve the above-described problem, and does not require a tool for avoiding the contact between the manhole cover mounting portion of the manhole cover and the manhole cover receiving portion of the comb plate, and can easily attach the manhole cover. An object of the present invention is to obtain a floor plate device for a man conveyor that can prevent deformation of a decorative plate for a comb plate.
　この発明のマンコンベアの床板装置は、乗降口に設けられた櫛板と、前記乗降口に設けられたマンホールに前記櫛板に隣接して設けられたマンホール蓋と、を備えている。前記櫛板は、櫛板用化粧板と、前記櫛板用化粧板の下部に、前記マンホール蓋の方向に突出した状態で前記櫛板用化粧板と一体に設けられた櫛板用裏板と、を備え、マンホール蓋受け部が前記櫛板用裏板の前記櫛板用化粧板から前記マンホール蓋の方向に突出した部分により構成され、前記マンホール蓋は、マンホール蓋用化粧板と、前記マンホール蓋用化粧板の下部に、前記マンホール蓋用化粧板と一体に設けられたマンホール蓋用裏板と、を備え、マンホール蓋取付部が前記マンホール蓋用裏板の前記櫛板の側の端部により構成され、前記マンホール蓋が、前記マンホール蓋取付部を前記マンホール蓋受け部に載置させて、前記マンホールに設けられており、面取り部が、前記マンホール蓋受け部の前記マンホール蓋の側の上側角部、および前記マンホール蓋取付部の前記櫛板の側の下側角部の少なくとも一方に形成されている。 The floor plate device for a man conveyor according to the present invention includes a comb plate provided at the entrance and a manhole cover provided adjacent to the comb plate at a manhole provided at the entrance. The comb plate includes: a comb plate decorative plate; and a comb plate back plate provided integrally with the comb plate decorative plate in a state of projecting toward the manhole cover at a lower portion of the comb plate decorative plate. The manhole cover receiving portion is configured by a portion of the back plate for the comb plate protruding from the comb plate decorative plate in the direction of the manhole cover. The manhole cover includes a manhole cover decorative plate and the manhole. A manhole cover back plate provided integrally with the manhole cover decorative plate at a lower portion of the cover decorative plate, and a manhole cover mounting portion is an end of the manhole cover back plate on the side of the comb plate The manhole cover is provided in the manhole by placing the manhole cover mounting portion on the manhole cover receiving portion, and a chamfered portion is provided on the manhole cover side of the manhole cover receiving portion.

　なお、他の構成は、上記実施の形態１と同様に構成されている。 The portion of the comb plate back plate 13 </ b> B that protrudes from the comb plate decorative plate 12 toward the tread plate 4 constitutes the comb attachment portion 14. A portion of the comb plate back plate 13 </ b> B protruding from the comb plate decorative plate 12 toward the first manhole cover 6 constitutes a base 33. The mounting recess 32 is formed by recessing the upper surface side of the end portion of the base portion 33 on the first manhole cover 6 side. The chamfering member 34 has a square surface 17, is mounted in the mounting recess 32, and is fastened and fixed to the base 33 by a screw 35. The base 33 and the chamfer member 34 constitute a manhole cover receiving portion 15B. A square surface 17 is formed at an upper corner portion of the manhole cover receiving portion 15B on the first manhole cover 6 side, that is, an upper corner portion of the chamfering member 34 on the first manhole cover 6 side. This square surface 17 is provided continuously over the entire region in the width direction of the comb plate 2B.
Other configurations are the same as those in the first embodiment.
　実施の形態３では、第１マンホール蓋６を取り付ける際に、第１マンホール蓋６のマンホール蓋取付部２０が櫛板２Ｂのマンホール蓋受け部１５Ｂに当接した後、第１マンホール蓋６を押し込むことで、マンホール蓋取付部２０の角面２１が、面取り部材３４の角面１７上をスライド移動し、マンホール蓋取付部２０がマンホール蓋受け部１５Ｂに乗り上がる。
　したがって、実施の形態３においても、上記実施の形態１と同様の効果が得られる。 In the third embodiment, when the first manhole cover 6 is attached, the first manhole cover 6 is pushed in after the manhole cover mounting portion 20 of the first manhole cover 6 contacts the manhole cover receiving portion 15B of the comb plate 2B. Thus, the corner surface 21 of the manhole cover mounting portion 20 slides on the corner surface 17 of the chamfer member 34, and the manhole cover mounting portion 20 rides on the manhole cover receiving portion 15B.
Therefore, also in Embodiment 3, the same effect as in Embodiment 1 can be obtained.
　ここで、角面１７の表面に傷が付くと、第１マンホール蓋６の取り付け作業における第１マンホール蓋６の押し込み力が増大する。この実施の形態３によれば、面取り部材３４が基部３３に着脱可能に取り付けられているので、角面１７の表面に傷が付けば、面取り部材３４を新しい面取り部材３４に簡易に交換することができる。そこで、第１マンホール蓋６の押し込み力の増大に起因する第１マンホール蓋６の取り付け作業性の悪化を抑えることができる。 Here, when the surface of the square surface 17 is scratched, the pushing force of the first manhole cover 6 in the mounting operation of the first manhole cover 6 increases. According to the third embodiment, since the chamfer member 34 is detachably attached to the base 33, the chamfer member 34 can be easily replaced with a new chamfer member 34 if the surface of the square surface 17 is damaged. Can do. Therefore, it is possible to suppress deterioration in workability of attaching the first manhole cover 6 due to an increase in the pushing force of the first manhole cover 6.
　また、面取り部材３４を、櫛板用裏板１３Ｂの基部３３および第１マンホール蓋用裏板１９の材料より硬い材料で作製すれば、角面１７に傷が付きにくくなり、面取り部材３４の寿命が長くなる。櫛板用裏板１３Ｂの基部３３および第１マンホール蓋用裏板１９は一般的に鉄製であるので、例えば、面取り部材３４をステンレス製とすればよい。 Further, if the chamfer member 34 is made of a material harder than the material of the base 33 of the comb plate back plate 13B and the first manhole cover back plate 19, the corner surface 17 is hardly damaged, and the life of the chamfer member 34 is increased. Becomes longer. Since the base 33 of the comb plate back plate 13B and the first manhole cover back plate 19 are generally made of iron, for example, the chamfer member 34 may be made of stainless steel.
　なお、上記実施の形態３では、角面１７が面取り部材３４に形成されているが、丸面３０が面取り部材３４に形成されてもよい。
　また、上記実施の形態３では、マンホール蓋受け部が基部と面取り部材とで構成されているが、マンホール蓋取付部が基部と面取り部材とで構成されてもよく、マンホール蓋受け部とマンホール蓋取付部の両者が基部と面取り部材とで構成されてもよい。 In the third embodiment, the square surface 17 is formed on the chamfer member 34, but the round surface 30 may be formed on the chamfer member 34.
In the third embodiment, the manhole cover receiving part is composed of a base part and a chamfering member. However, the manhole cover attaching part may be composed of a base part and a chamfering member. Both of the attachment portions may be composed of a base portion and a chamfer member.
