Description

The present invention relates to a floor cover for a passenger conveyor.

BACKGROUND ART Conventional floor covers for passenger conveyors are known in which easy-to-see floor characters are formed by directly processing the surface of the floor cover in a embossed manner in order to call passengers' attention. A similar purpose but different structure is the floor cover with an embedded indicator.

For example, when the direction of operation of one passenger conveyor is reversed depending on the time of day, etc., there is a desire to always display upright floor number characters from either direction in accordance with the line-of-sight direction of passengers according to the direction of operation. There is

In order to meet this demand, it is necessary to have a display function that can appropriately change floor characters on the floor cover of the doorway of the passenger conveyor. In order to realize this, it is known to arrange an electronic image display on the passenger conveyor floor cover and control the display contents by an electronic drive circuit (for example, Patent Document 1).

Japanese Patent Application Laid-Open No. 2004-99198

However, a floor cover with floor characters carved on its surface needs to be replaced in order to change the display. On the other hand, the electronic image display device disclosed in Patent Document 1 can change the display content instantaneously as required, such as by changing the character direction in conjunction with the running direction of the passenger conveyor. It has the drawback of disappearing. That is, the electronic image display not only increases the total weight of the floor cover by the amount of the display, but also requires a dedicated control device and wiring, and also has problems such as power consumption.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object thereof is to provide a passenger conveyor floor cover that can change the display of the floor cover according to the driving direction without exchanging the floor cover. to provide.

The present invention for solving the above problems is a floor cover for a passenger conveyor that serves as both floors at both end portions in the conveying direction and a machine room top cover in which a driving device is arranged at least one of the both end portions, It has multiple grooves that intersect with the direction of travel and multiple display areas for each line of sight with respect to the sides of the grooves. be.

According to the present invention, it is possible to provide a floor cover for a passenger conveyor that can change the display of the floor cover without exchanging the floor cover when changing the driving direction.

BRIEF DESCRIPTION OF THE DRAWINGS It is a schematic block diagram for demonstrating the application object of the floor cover for passenger conveyors (henceforth "this floor cover") which concerns on this embodiment. 1. It is a schematic explanatory drawing which shows the difference according to the entrance and exit according to the top and bottom of a driving|running direction about the inclination angle (slope angle) of the groove side surface with respect to the groove bottom face of the floor cover shown in FIG. . FIG. 3 is a schematic explanatory diagram showing the difference in line of sight of a passenger that makes the slope angle shown in FIG.

An embodiment will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram of a passenger conveyor for explaining application targets of the floor covers 12A and 12B. The upper floor lid 12A and the lower floor lid 12B are collectively referred to as the floor lid 12 when they are not distinguished from each other. As shown in FIG. 1, an escalator 1, which is one form of a passenger conveyor device, includes a frame body 2, a plurality of steps 4, a machine room 5, a drive device 6, a pair of left and right handrails 7, and an endless A handrail 8 , a control device 9 , a drive chain 10 and a terminal gear 11 are provided.

The frame 2 is installed in a building structure and spanned between one floor and the other floor. The frame body 2 also includes an upper horizontal frame 2A, a lower horizontal frame 2B, and an intermediate inclined portion frame 2C. A machine room 5 is provided in the upper horizontal frame 2A.

A plurality of steps 4 are accommodated in the frame 2 and are endlessly connected to cyclically move between the upper entrance/exit 3A and the lower entrance/exit 3B. A drive device 6 is provided in the machine room 5 and drives the step 4 . Details of the driving device 6 will be described later. A pair of left and right handrails 7 are erected on the frame body 2 along the moving direction of the step 4 . An end rail 8 is guided along the periphery of the balustrade 7 and driven synchronously with the steps 4 .

The terminal gear 11 is driven by the driving device 6 via the drive chain 10 . A control device 9 is installed in the machine room 5 and controls the drive device 6 . When the driving device 6 is driven under the control of the control device 9, the output of the driving device 6 is transmitted to the step 4 and the handrail 8 via the drive chain 10 and the terminal gear 11, and the step 4 and the handrail 8 perform the circular motion. It moves upwards or downwards as it accompanies.

The step 4 moves in synchronism with the handrail 8, and conveys passengers from the upper doorway 3A to the lower doorway 3B when the elevator is descending, and from the lower doorway 3B to the upper doorway 3A when the elevator is ascending. transport passengers to

Next, the configuration and function of the floor lid 12 will be described with reference to FIGS. 2 and 3. FIG. FIG. 2 shows the inclination angle (slope angle) of the groove side surface with respect to the groove bottom surface (see 24 in FIG. 3) of the floor covers 12A and 12B shown in FIG. FIG. 10 is a schematic explanatory diagram showing the difference according to the mouth. As shown in FIG. 2, the line of sight of the passenger looking at the floor cover 12 differs depending on whether the escalator 1 is in ascending operation (UP operation) or descending (DN operation).

FIG. 3 is a schematic explanatory diagram showing the difference in the passenger's line of sight that makes the gradient angles α, β, and γ shown in FIG. be. As shown in FIG. 3, the floor cover 12 can change the indicia depicted on its surface 22 according to different viewing angles. That is, the contents displayed uniformly on only one side of the groove can be seen only on one side depending on the viewing direction.

Regarding the gradient angles (here, simply called "angles") α, β, and γ of the groove side surface with respect to the horizontal plane, when applying the mathematical definition of "groove slope", they are usually acute angles. Although it is indicated by α, it may correspond to an obtuse angle 26 that is easy to measure. The acute angle α and the obtuse angle 26 are complementary angles, and the sum of the two angles is 180°.

The angles α, β, γ will be described in more detail with reference to FIGS. 2 and 3. FIG. The angle α is the angle with respect to the horizontal plane of the groove side surface facing the step at the escalator exit during DN operation. The angle β is the angle with respect to the horizontal plane of the side surface of the groove facing away from the step at the entrance of the escalator, regardless of whether the UP or DN direction is running.

On the other hand, the angle γ is the angle with respect to the horizontal surface of the groove side surface facing the step at the escalator exit during UP operation, and is closer to 90° than the angles α and β. In the case of using an obtuse angle 26 that is easy to measure, the angle of the groove side surface (see 25A in FIG. 3) with respect to the groove bottom surface (see 24 in FIG. 3) may be used. In that case, the bottom surface of the groove may be regarded as a horizontal plane, and there is no need to be strict.

In these definitions, the relative magnitudes of the angles α, β, and γ are α<β<γ. Here, if α≈β, it is preferable to set two types of slope angles as indicated by the magnitude relationship of α≈β<γ. This floor cover 12 is configured as described above, so that the display drawn on the surface 22 of the floor cover 12 can be changed to suit the line of sight of passengers without replacing the floor cover 12 when the driving direction is changed. It is possible to

As shown in FIG. 3, a convex portion 23 and a concave portion 24 are provided on the surface 22 of the floor lid 12, and character printed portions 25A and 25B (both of which are Together, they form a “display area 25”).

The character printing portion 25A is set at an inclination angle α perpendicular to the line of sight 27A from the left in FIG. The character printed portion 25B is set at a gradient angle β perpendicular to the line of sight 27B from the right side of FIG.

As described above, these floor characters 28A and 28B are visually recognized as erect characters in the line of sight determined by the direction of travel of the person viewing them. Since the floor cover 12 is constructed in this manner, it is possible to display the floor number characters that are always displayed in an upright state from either direction, conforming to the line-of-sight direction of the passenger according to the driving direction.

The passenger conveyor floor cover (main floor cover) 12 according to the embodiment of the present invention can be summarized as follows.
[1] This floor cover 12 is a passenger conveyor floor cover 12 that serves as both the floors of both ends in the conveying direction and the upper cover of the machine room 5 in which the driving device 6 is arranged at least one of the ends. It has a plurality of grooves intersecting with the traveling direction and a plurality of display areas 25 for each viewing direction with respect to the side surface of the groove, and the slope angles α, β, γ of the side surfaces having the display areas 25 are different from the passenger at both ends. is formed according to the line-of-sight direction of

The floor cover 12 is configured in this way, so that different displays are shown according to the direction of the line of sight of the passenger moving across the front and rear of the floor cover 12 at the doorway of the passenger conveyor. That is, the display of the floor cover 12 can be changed without exchanging the floor cover 12 when the driving direction is changed.

[2] For this passenger conveyor floor cover, it is preferable that two types of slope angles are set for each line-of-sight direction with respect to the groove. For example, at the exit during DN operation, the slope slope angle is set to α. At the entrance during UP/DN operation, the slope angle is set to β. At the exit during UP operation, the slope slope angle is γ.

First, at the exit during DN operation, passengers in the downward direction have a line of sight that looks down on the floor cover 12B below from a high viewpoint. Corresponding to this line of sight direction, a slope gradient angle α is set in order to clearly and easily see the characters drawn on the side surface of the groove on the surface of the floor cover.

In addition, at the entrance during UP/DN operation, the line of sight is such that the passenger looks down on the floor cover 12B from a viewpoint about his/her own height. In order to make the characters drawn on the side surface of the groove on the surface of the floor lid clearer and easier to see, the slope angle is set to β.

On the other hand, at the exit during UP operation, passengers in the ascending direction have a line of sight that looks up at the upper floor cover 12A from a low viewpoint. In order to make the characters drawn on the side surface of the groove on the surface 22 of the floor cover 12 clearer and easier to see, the slope angle is set to γ.

In these definitions, α<β<γ. Here, if α≈β, it is preferable to set two types of slope angles as indicated by the magnitude relationship of α≈β<γ. Since the floor cover is configured in this way, the display of the floor cover can be changed without exchanging the floor cover when changing the driving direction.

[3] In this passenger conveyor floor cover, it is preferable that two types of characters are drawn in the display area in an upright state corresponding to the direction of the line of sight to indicate the number of floors. Since the main floor cover 12 is configured in this manner, it is possible to display the floor number characters that are always displayed in an upright state from either direction, conforming to the line-of-sight direction of the passenger according to the driving direction. Therefore, when the driving direction is changed, the display of the floor cover can be changed without exchanging the floor cover.

In this way, the floor cover 12 can simplify the floor cover of a passenger conveyor in which an electric display capable of displaying the number of floors and the like is embedded, and can achieve the same function. That is, in the passenger conveyor, it is possible to display in an upright state and easily viewable from either direction in accordance with the line-of-sight direction of the passengers according to the up-and-down reversal of the operating direction.
