Description

この発明は、踏板表面に滑り止めが設けられたマンコンベアの踏板に関するものである。   The present invention relates to a tread of a man conveyor having a slip stopper provided on a tread surface.

従来のマンコンベア用踏板では、表面に設けられたスリップ防止用凹部によって、表面の摩擦係数を高めて、乗客の履物の裏面と引っ掛かることにより、乗客の滑りを低減させる(例えば、特許文献1参照)。   In the conventional man-conveyor tread, the slip coefficient of the passenger is reduced by increasing the friction coefficient of the surface by the recess for preventing slip provided on the surface and being caught on the back of the footwear of the passenger (for example, see Patent Document 1). ).

特開平4−106090号公報JP-A-4-106090

上記のような従来のマンコンベア用踏板では、踏板上で停止している乗客の滑りを低減させていたが、踏板上を歩行する乗客も多く、乗客の歩行方向によって、乗客の踏板に掛ける力が異なるため、スリップ防止用凹部に乗客がつまずくことがあり、乗客の歩行の障害となることがあった。   In the conventional man-conveyor treads as described above, the slipping of passengers stopped on the treads is reduced, but there are many passengers walking on the treads, and the force applied to the passenger treads depending on the walking direction of the passengers Therefore, the passenger sometimes trips into the slip prevention recess, which sometimes obstructs the walking of the passenger.

この発明のマンコンベアの踏板は、鉛直面に対する傾斜角度が互いに異なる第1及び第2の傾斜面を含んだ溝によって、乗客の滑りを低減させることができるとともに、歩行する乗客がいた場合にも、歩行中の乗客のつまずきを低減させ、乗客の歩行方向に限らず、乗客が円滑に踏板上を歩行することができる。   The tread of the man conveyor according to the present invention can reduce the slip of the passengers by the grooves including the first and second inclined surfaces having different inclination angles with respect to the vertical surface, and also when there is a walking passenger It is possible to reduce the tripping of passengers while walking, and not only the walking direction of the passengers but also the passengers can smoothly walk on the tread.

以下、この発明を実施するための最良の形態について、図面を参照して説明する。
実施の形態1.
図1は、この発明の実施の形態1によるエスカレータのステップを示す斜視図である。
図において、フレーム(アングル)1の上面部には、踏板2が取り付けられている。また、フレーム1の正面部には、蹴上げ板3が取り付けられている。
The best mode for carrying out the present invention will be described below with reference to the drawings.
Embodiment 1 FIG.
1 is a perspective view showing steps of an escalator according to Embodiment 1 of the present invention.
In the figure, a tread plate 2 is attached to the upper surface of a frame (angle) 1. A kick-up plate 3 is attached to the front portion of the frame 1.

図2は、図1のステップの一部を拡大して示す斜視図である。踏板2の表面には、ステップの進行方向に平行な複数のクリート2aが設けられている。クリート2aは、エスカレータ乗降口に設けられたコム(図示せず)に係合される。クリート2aがコムに係合されることによって、エスカレータ乗降口で異物等が噛み込まれるのを防ぐ。踏板2のクリート2aの上面には、ステップの進行方向に直交する複数の溝2bが互いに間隔を置いて設けられている。   FIG. 2 is an enlarged perspective view showing a part of the steps of FIG. A plurality of cleats 2a are provided on the surface of the tread board 2 in parallel with the direction in which the step proceeds. Cleat 2a is engaged with a comb (not shown) provided at the escalator entrance. When the cleat 2a is engaged with the comb, foreign matter or the like is prevented from being caught at the escalator entrance. On the upper surface of the cleat 2a of the tread board 2, a plurality of grooves 2b orthogonal to the direction in which the step proceeds are provided at intervals.

図3は、図1のステップの断面図である。溝2bの断面形状は、略V字状である。溝2bの内壁は、第1及び第2の傾斜面2c,2dを含んでいる。第1の傾斜面2cは、蹴上げ板3側に位置している。第2の傾斜面2dは、反蹴上げ板3側に位置している。第1及び第2の傾斜面2c,2dは、踏板2が水平に置かれたときに鉛直面に対する傾斜角度θ1,θ2が互いに異なる。具体的には、鉛直面に対する第2の傾斜面の傾斜角度θ2は、鉛直面に対する第1の傾斜面の傾斜角度θ1よりも大きい(θ1<θ2)。   FIG. 3 is a cross-sectional view of the steps of FIG. The cross-sectional shape of the groove 2b is substantially V-shaped. The inner wall of the groove 2b includes first and second inclined surfaces 2c and 2d. The 1st inclined surface 2c is located in the kick board 3 side. The 2nd inclined surface 2d is located in the anti-kick-up board 3 side. The first and second inclined surfaces 2c and 2d are different from each other in inclination angles θ1 and θ2 with respect to the vertical surface when the tread 2 is placed horizontally. Specifically, the inclination angle θ2 of the second inclined surface with respect to the vertical surface is larger than the inclination angle θ1 of the first inclined surface with respect to the vertical surface (θ1 <θ2).

ここで、溝2bの加工方法の一例について説明する。溝2bの形状が形成された踏板2のアルミダイキャスト(鋳型鋳造)用の金型によって、踏板2の完成時に、踏板2の表面に溝2bが形成される。また、他の加工方法の一例では、アルミダイキャスト、又は鋼板の折り曲げによって完成された踏板2に機械加工等を施すことによって、踏板2の表面に溝2bが形成(付加)される。   Here, an example of the processing method of the groove 2b will be described. A groove 2b is formed on the surface of the tread 2 when the tread 2 is completed by a die for aluminum die casting (mold casting) of the tread 2 in which the shape of the groove 2b is formed. In another example of the processing method, a groove 2b is formed (added) on the surface of the tread plate 2 by machining or the like on the tread plate 2 completed by aluminum die casting or bending of the steel plate.

上記のようなエスカレータのステップでは、乗客の歩行方向を考慮し、鉛直面に対する傾斜角度が互いに異なる傾斜面を含んだ溝2bを踏板2の表面に設けたので、踏板2の表面の摩擦係数を乗客の歩行方向に対応させることができる。   In the escalator step as described above, the groove 2b including the inclined surfaces having different inclination angles with respect to the vertical surface is provided on the surface of the tread plate 2 in consideration of the walking direction of the passenger. This can correspond to the walking direction of the passenger.

また、図4は、踏板2に対する乗客の下降方向への歩行動作を示す説明図である。下降方向に進行しているステップ上を下降方向へ歩行する乗客が、下段のステップに片足を踏み出し、着地した(踏ん張る)際に、踏板2の上面と乗客の足との接触点に乗客の体重が掛かることによって、蹴上げ板3方向に力10が発生される。そして、第1の傾斜面2cに乗客の履物の裏面が引っ掛かることによって、摩擦力が生じ、発生した力10が打ち消される。   FIG. 4 is an explanatory view showing the walking motion of the passenger in the descending direction with respect to the tread board 2. When a passenger walking in a descending direction on a step moving in a descending direction steps out on one step in the lower step and lands (stretches), the weight of the passenger is at the contact point between the upper surface of the tread board 2 and the passenger's foot. As a result, a force 10 is generated in the direction of the kick-up plate 3. And when the back surface of a passenger's footwear catches on the 1st inclined surface 2c, a frictional force arises and the generated force 10 is negated.

さらに、図5は、踏板2に対する乗客の上昇方向への歩行動作を示す説明図である。上昇方向に進行しているステップ上を上昇方向へ歩行する乗客が、上段のステップに一方の足を踏み出した際に、一方の足の履物の裏面は、上段の踏板2の表面の第2の傾斜面2dに引っ掛かりにくく、乗客が溝2bにつまずきにくい。さらにまた、下段の踏板2の上面と他方の足との接触点に乗客の体重が掛かることによって、蹴上げ板3方向に力11が発生される。そして、下段の踏板2の第1の傾斜面2cに乗客の履物の裏面が引っ掛かることによって、摩擦力が生じ、発生した力11が打ち消される。   Furthermore, FIG. 5 is explanatory drawing which shows the walk operation | movement to the rising direction of the passenger with respect to the tread board 2. FIG. When a passenger walking in the upward direction on the step traveling in the upward direction steps out one foot in the upper step, the back of the footwear on one foot is the second of the surface of the upper footboard 2 It is difficult to get caught on the inclined surface 2d, and it is difficult for passengers to trip into the groove 2b. Furthermore, when the passenger's weight is applied to the contact point between the upper surface of the lower tread 2 and the other foot, a force 11 is generated in the direction of the kick-up plate 3. Then, when the back surface of the footwear of the passenger is caught on the first inclined surface 2c of the lower tread 2, a frictional force is generated, and the generated force 11 is canceled out.

これにより、乗客の滑りを低減させることができるとともに、乗客がステップ上を上昇方向へ歩行する場合と、乗客がステップ上を下降方向へ歩行する場合とでは、踏板2表面の摩擦係数が異なるため、歩行する乗客がいた場合にも、乗客が円滑に踏板2上を歩行することができる。   As a result, the slip of the passenger can be reduced, and the coefficient of friction of the surface of the tread 2 is different between when the passenger walks in the upward direction on the step and when the passenger walks in the downward direction on the step. Even when there is a walking passenger, the passenger can smoothly walk on the tread 2.

なお、実施の形態1では、エスカレータのステップであるが、傾斜形の動く歩道の踏板に実施の形態1と同じ構成を施すことにより、同様の効果を得ることができる。   Although the first embodiment is an escalator step, the same effect can be obtained by applying the same configuration as the first embodiment to the step board of the inclined moving sidewalk.

実施の形態2.
次に、この発明の実施の形態2について説明する。図6は、この発明の実施の形態2によるエスカレータのステップを示す拡大図である。実施の形態1では、溝2bが表面に均一に配置されていたが、乗客に対して踏板2の境界を示す注意標識帯を形成するように踏板2の蹴上げ板3側近傍に、溝2bが集中して配置されている。即ち、溝2bの配置密度が蹴上げ板3側の端部近傍で高くなっている。他の構成は実施の形態1と同様である。
Embodiment 2. FIG.
Next, a second embodiment of the present invention will be described. FIG. 6 is an enlarged view showing steps of the escalator according to the second embodiment of the present invention. In Embodiment 1, the grooves 2b are uniformly arranged on the surface. However, the grooves 2b are formed in the vicinity of the kick-up board 3 side of the tread board 2 so as to form a warning sign band indicating the boundary of the tread board 2 to the passenger. It is concentrated. That is, the arrangement density of the grooves 2b is high in the vicinity of the end portion on the kick-up plate 3 side. Other configurations are the same as those in the first embodiment.

上記のようなエスカレータのステップでは、溝2bが乗客に対して踏板2の境界を示す注意標識帯を形成するように踏板2の蹴上げ板3側の端部近傍に集中して配置されているので、乗客の滑りを低減させることができるとともに、踏板2の境界の乗客に対する視認性を向上させることができる。   In the escalator step as described above, the groove 2b is concentrated in the vicinity of the end portion of the step board 2 on the side of the lift plate 3 so as to form a warning sign band indicating the boundary of the step board 2 with respect to the passenger. The slip of the passenger can be reduced, and the visibility for the passenger at the boundary of the tread board 2 can be improved.

なお、実施の形態2では、溝2bが踏板2の蹴上げ板3側の端部近傍に集中して配置されていたが、蹴上げ板側の端部近傍に限るものではなく、反蹴上げ板側の端部近傍、及び踏板の測端部近傍に集中して配置されてもよい。これにより、スカートガード及び上段ステップと踏板との境界の乗客に対する視認性を向上させることができる。   In the second embodiment, the grooves 2b are concentrated in the vicinity of the end of the tread plate 2 on the side of the kick-up plate 3. However, the groove 2b is not limited to the vicinity of the end on the side of the kick-up plate. You may concentrate and arrange | position in the edge part vicinity and the measurement part vicinity of a tread. Thereby, the visibility with respect to the passenger of the boundary of a skirt guard and an upper step, and a tread can be improved.

また、溝を乗客の注意を喚起させる色(例えば黄色)に着色させてもよい。これにより、乗客に対する踏板の境界の視認性をさらに向上させることができる。   Moreover, you may color a groove | channel (for example, yellow) which alerts a passenger's attention. Thereby, the visibility of the boundary of the tread board with respect to the passenger can be further improved.

さらに、実施の形態2では、踏板2の蹴上げ板3側の端部近傍にのみ溝2bが設けられていたが、踏板全体に溝を設けた上で、踏板の蹴上げ板側に対する溝の配置密度を高くしてもよい。   Further, in the second embodiment, the groove 2b is provided only in the vicinity of the end portion on the side of the kick-up plate 3 of the tread plate 2. However, after the groove is provided on the entire tread plate, the arrangement density of the grooves with respect to the side of the step-up plate is increased. May be raised.

さらにまた、実施の形態1,2では、溝2bの断面形状が略V字状であったが、略V字状に限るものではなく、例えば台形状など溝の内壁が第1及び第2の傾斜面を含んでいれば他の断面形状であってもよい。   In the first and second embodiments, the cross-sectional shape of the groove 2b is substantially V-shaped. However, the shape is not limited to the substantially V-shape, and the inner wall of the groove such as a trapezoidal shape is the first and second shapes. Other cross-sectional shapes may be used as long as they include an inclined surface.
