Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger conveyor such as an escalator, and more particularly to a passenger conveyor characterized by a height dimension of a support frame for movably storing steps.

[0002]

2. Description of the Related Art FIG. 4 is a perspective view showing the appearance of a conventional passenger conveyor such as an escalator. The escalator shown in FIG. 4 shows a state before being installed on the side of the stairs 50 of the station, for example, a state where the escalator is simply placed on the stairs 50.

The conventional escalator shown in FIG. 4 includes a plurality of steps (not shown) in a support frame 51 having an upper horizontal portion, an intermediate inclined portion, and a lower horizontal portion. This step performs a circular movement including a forward route for carrying passengers and a return route after returning from the passengers. A lower floor 52 that forms a passenger entrance / exit, for example, a passenger entrance is provided on an upper surface portion on the lower floor side of the support frame 51, and a lower machine room 53 is provided inside the support frame 51 below the lower floor 52. Is provided. In addition, an upper floor 54 that forms a passenger entrance / exit, for example, an exit, is provided on the upper floor side of the upper floor side of the support frame 51, and an upper machine room is provided inside the support frame 51 below the upper floor 54. 55 are provided. On the upper side of the support frame 51,
A skirt guard 56 extending upward from each of both sides of a step (not shown);
And a balustrade 58 to which a moving handrail 57 that moves in synchronization with a step (not shown) is mounted.

[0004] The escalator is an escalator conventionally provided in a department store, a station, or the like, and each step (not shown) has a passenger's foot positioned on the tread in the moving direction of the step. In this case, the depth of the tread is set in advance so as to be larger than the size of the foot of the passenger. In the following, this step is referred to as “normal-sized step”.

The dimensions of the main structure of the conventional escalator shown in FIG. 4 will be described. The height k of the support frame 51 at the lower entrance A in FIG.
1200 [mm]. The sum of the height h1 of the balustrade 58 at the lower entrance A and the height h3 of the skirt guard 56 from the tread surface of the step (not shown) to the lower end of the inner deck cover 59 is 850 to 950 [m
m].

[0006] Looking at the dimension of the intermediate inclined portion B in the direction orthogonal to the direction of movement of the steps, the height dimension k of the support frame 51 is 800 to 1200 [mm]. The sum of the height h1 of the balustrade 58 in the same direction and the height h3 of the skirt guard 56 from the tread surface of the step (not shown) to the lower end of the inner deck cover 59 is 700 to 8
00 [mm].

The height dimension k of the support frame 51 at the upper exit C is 1000 to 1200 [mm]. Also, the height dimension h of the balustrade 58 at the upper exit C
The sum of 1 and the height h3 of the skirt guard 56 from the tread surface of the step (not shown) to the lower end of the inner deck cover 59 is 850 to 950 [mm].

As can be seen from the above-described dimensions, in the conventional ordinary escalator shown in FIG. 4, the height dimension h1 of the balustrade 58 is located at any of the lower exit A, the middle inclined portion B, and the upper exit C. The height dimension k of the support frame 51 is set to be larger than that of.

As described above, the reason why the height dimension k of the support frame 51 is increased is that the forward orbit of the circulation path of the step (not shown) is located at the uppermost position, and the predetermined position is located below the front wheel orbit. The rear wheel track is located at an interval, the backward track of the step (not shown) after reversing at the terminal, the front wheel track is located at the lowest position, and the rear wheel track is located at a predetermined interval above it. Due to doing so.

That is, since the front wheel trajectory and the rear wheel trajectory are provided at a predetermined interval on both the forward and return paths, the vertical dimension of the circulating track is equal to the front wheel trajectory arranged at the uppermost position of the forward path. And the front wheel track disposed at the lowermost position of the return path, and has a large size defined by the front-wheel track. This is because the dimensions also increase.

[0011]

When the escalator shown in FIG. 4 is to be installed, the height of the support frame 51 may be smaller than that of the conventional escalator depending on the installation environment. May be requested. For example, in the case where a part of the stairs 50 of the station is removed and a new escalator is installed as shown in FIG. 4, the space between the tread of the steps and the ceiling is sufficiently secured. Therefore, it is necessary to install the escalator with as little removal of the stairs as possible. In order to realize this, as described above, it is necessary to consider that the height of the support frame 51 is made lower than that of the conventional escalator. Therefore, in recent years, development of a technology that meets such a demand has been expected.

Japanese Unexamined Patent Publication (Kokai) No. 55-151482 discloses that the depth of a tread of a step is set to about half of that of a normal step, and the step is reduced in size in this manner, thereby inverting the step in the terminal portion. An escalator has been proposed in which the radius of rotation of the escalator is made smaller than that of a normal escalator, whereby the height of the support frame can be reduced. However, this escalator is intended to position the passenger in a direction perpendicular to the direction of travel, that is, in a lateral direction, and to place the passenger's foot on each of the treads of two adjacent steps that generate a step. This is an escalator with a special transport form. In this escalator, while the passenger is being transported, the passenger is forced to take an unreasonable posture, and there is a problem in the safety at the time of getting on and off.Therefore, the technology described in this publication has a problem in practicality. .
Therefore, it cannot be applied to ordinary escalators that have been generally used.
