Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a passenger conveyor system.

First, a conventional passenger conveyor system will be explained with reference to FIGS. 1 and 2.

In the figure, 1 is a fixed body consisting of the main frame of the passenger conveyor, 2 is an endless tread chain arranged on this,
Reference numeral 2a denotes an engager made of rack teeth provided on the inside of the endless annular shape of the treadle chain 2, 3 is a treadle, 3a is a shaft provided on this and both ends of which are inserted into the treadle chain 2, and 3b is the shaft 3a. Rollers 4 are pivotally connected to both ends of the rollers 3b and 4 provided on the fixed body 1, respectively.
5 is a drive shaft pivotally connected to the fixed body 1, 6 is a gear fixed to this and engaged with the engager 2a, and 7 is a rail provided on the fixed body 1 to connect the gear 6 and the engager 2a. A contact member 8 is fixed to the drive shaft 5 to prevent the tread chain 2 from rising due to the engagement of the rail 4.
A drive wheel 9 disposed on the outside is an endless moving handrail with a portion wrapped around the drive wheel 8.

That is, the tread chain 2 is driven, thereby the tread 3 is moved, and at the same time, the drive wheel 8 is rotated via the engager 2a and the gear 6, and the movable handrail 9 is moved by the frictional force of the drive wheel 8. There is. However, since the drive shaft 5 is disposed below the rail 4, the movable handrail 9 passes through the outside of the rail 4 and is wrapped around the drive wheel 8, which increases the width of the fixed body 1. Therefore, there was a problem in that a large space was required to install the passenger conveyor. Furthermore, since the drive mechanism for the moving handrail 9, such as the gear 6, is disposed below the footboard 3, there is a problem in that the installation and maintenance work thereof becomes complicated. Also, a gear 6 is provided below the engager 2a.
Since this is provided, an abutment body 7 to prevent the tread chain 2 from lifting up is required, which increases the number of parts, resulting in a complicated device.

The present invention aims to eliminate the above-mentioned drawbacks and to provide a passenger conveyor device in which the driving portion of the moving handrail can be easily installed and maintained.

An embodiment of the present invention will be described below with reference to FIGS. 3 and 4.

In the figure, the same reference numerals as in FIGS. 1 and 2 indicate corresponding parts, 2a is an engager made of rack teeth provided on the outside of the endlessly arranged tread chain 2, and 10 is a protrusion from the fixed body 1. An arm 11 is fixed to the tip of the shaft and hangs down, 5 is a shaft protruding from the lower end of the arm 11, and 6 is pivotally connected to the shaft 5 to connect the engager 2a.
12 is a second gear engaged with the first gear 6 and pivotally connected to the shaft 10; 8 is an integrally provided second gear and abuts against one side of the handrail 9. A driving rotating body consisting of a driving roller, 13 is a fixed body 1
14 is a shaft protruding from the bracket;
is a contact body consisting of an auxiliary roller pivotally attached to the shaft 14 and in contact with the other surface of the moving handrail 9.

That is, the operation of the treadle chain 2 causes the first gear 6, which is engaged with the engager 2a thereof from above, to rotate, and this rotation is transmitted to the second gear 12, causing the drive rotary body 8 to rotate. On the other hand, since the abutting body 15 is disposed facing the drive rotary body 8 via the moving handrail 9 and presses the movable handrail 9 by adjusting the bracket 13, the rotation of the drive rotary body 8 causes friction. The force drives the moving handrail 9. In this way, the movable handrail 9 is driven by the first gear 6, the drive rotating body 8, etc. arranged above the tread chain 2. Therefore, the moving handrail 9 can be placed above the rail 4,
It becomes possible to arrange the moving handrail 9 at an upper position corresponding to the length of the shaft 3a. Therefore, since the first gear 6, the driving rotary body 8, etc. are arranged above the rail 4, their installation and maintenance work can be facilitated, and their costs can be reduced. Along with this, a handrail 9 that moves in the width direction of the fixed body 1 is also provided.
A space for driving is not required, the width of the fixed body 1 can be reduced, and a passenger conveyor device that can be easily installed in a narrow space is obtained. Furthermore, due to the engagement between the engager 2a and the first gear 6, a load is applied to push down the tread chain 2, but since this load is supported by the rail 4 via the roller 3b, the tread chain 2 There is no need for a member to prevent the device from falling, and the number of parts is reduced, resulting in a simpler device configuration. In addition, since the engaging member 2a is made of rough teeth, it is possible to downsize the engaging member 2a to the extent that it can correspond to the driving force of the moving handrail 9. Therefore, the diameter of the first gear 6 can be reduced, and the depth dimension of the fixed body 1 can be reduced. Therefore, the installation space for the passenger conveyor can also be saved in the depth direction of the fixed body 1. Further, since the rack teeth can be formed simultaneously with the pressing of the links of the tread chain 2, manufacturing costs can be reduced.

Further, the driving rotary body 8 in this embodiment is made of a gear, and one surface of the moving handrail 9 facing the gear is provided with rack-shaped teeth that engage with the teeth of the driving rotary body 8. It is clear that the same effect can be obtained even if

5 and 6 show other embodiments of the present invention. In the figures, the same reference numerals as in FIGS. 3 and 4 indicate corresponding parts, and 2a is a pin of the link of the tread chain 2 or The engaging element is composed of a shaft 3a, and 6 is a first gear engaged with the engaging element.

That is, since the first gear 6, the drive rotating body 8, etc. are arranged above the rail 4 in this embodiment as well, it is clear that the same effect as in the embodiments shown in FIGS. 3 and 4 can be obtained.

FIG. 7 also shows another embodiment of this invention.
In the figure, the same symbols as in Figures 3 and 4 indicate corresponding parts,
6 is a first gear engaged with two second gears 12 arranged in parallel.

That is, in this embodiment as well, the first gear 6, drive rotating body 8, etc. are arranged above the rail 4, so that the same effect as in the embodiments shown in FIGS. 3 and 4 can be obtained. In addition, in this embodiment, as shown in FIG. 7, the space required for the first and second gears 6 and 12 along the depth direction of the fixed body 1 is small, so the installation space related to the depth of the passenger conveyor is reduced. can do. Furthermore, in this embodiment, the number of first gears 6 is reduced, the device is simplified, and manufacturing costs can be reduced.

As explained above, the present invention drives the movable handrail via the drive rotary body by the first gear engaged with the tread chain from above, and arranges the movable handrail, the drive rotary body, etc. above the rail of the tread. This is what I did. As a result, a passenger conveyor device is realized in which installation and maintenance of the driving portion of the moving handrail can be easily performed.
