Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to an improvement in the deck structure of a balustrade device for a passenger conveyor, particularly a balustrade device suitable for a curved escalator.

[Prior Art] Generally, the deck of a curved escalator is composed of a three-dimensional curved surface. Therefore, in order to make a deck with this three-dimensional curved surface, it is customary to make it by press working, but this method has drawbacks such as the high cost of the press mold.

Therefore, some proposals have been made to make the deck from thin sheets.

Figures 3 to 6 show a conventional parapet device for a curved escalator as disclosed in, for example, Japanese Utility Model Application Publication No. 59-83860. Reference numeral 2 denotes a parapet erected along the longitudinal edge of the main frame 1, 2a a panel forming the main part of the parapet 2, 2b a movable handrail movably engaged with the upper edge of the panel 2a, 2c is an inner deck forming the upper surface of the base of the parapet 2, 2d is an outer deck opposite to the inner deck 2c, and both decks 2c, 2d
is formed of a thin flat plate such as a stainless steel plate. Reference numeral 3 indicates a plurality of support stands disposed at arbitrary intervals in the longitudinal direction on the lower surface side of both decks 2c and 2d;
is Patsuking.

However, since the decks 2c and 2d made of thin flat plates have low rigidity and are easily deformed when a person stands on the decks 2c and 2d, a support stand 3 is provided to prevent this deformation.

[Problem that the invention seeks to solve]

In the conventional balustrade device having the above configuration, since the support base 3 is not continuous in the longitudinal direction,
The decks 2c, 2d are weak where there is no support 3, and therefore, in order to provide sufficient strength to the decks 2c, 2d, the supports 3 must be installed at fairly narrow pitches. However, it is not easy to center and mount the upper surface of the support stand 3 so as to follow the three-dimensional curved surface of the decks 2c and 2d, and this, together with the large number of support stands 3, increases the manufacturing cost. ing.

Furthermore, no matter how narrow the pitches of the support platforms 3 are, there are gaps between adjacent support platforms 3, and if a force is applied to these areas from above the decks 2c, 2d, the decks 2c, 2d may dent locally. There is a problem.

In addition, since the support base 3 is discontinuous in the longitudinal direction, if the dimension in the height direction is off at even one point, the 7th
As shown in the figure, since the support base 3 is mounted at a fairly narrow pitch, the decks 2c and 2d are distorted at that portion, resulting in a disadvantage in that the design is unsightly.

Furthermore, since the packing 4 is not fixed over its entire length, there is a drawback that it may partially cave in or come out.

This invention was made to solve this problem, and even when a thin flat plate is used as the deck, there will be no locally weak points, and the passenger conveyor has great effects in terms of safety and design. The purpose is to provide a balustrade device.

[Means for solving problems]

The balustrade device for a passenger conveyor according to the present invention has a support rail for supporting and fixing the deck disposed along the longitudinal direction between at least the lower edge of the balustrade main body side of the deck made of a thin flat plate and the upper surface of the support base. be.

[Effect]

In this invention, since the lower edge of the deck is continuously supported and fixed in the longitudinal direction by the support rail, there will be no locally weak spots even if the deck is made of a thin flat plate.

〔Example〕

FIGS. 1 and 2 show an embodiment of the present invention, and the same reference numerals as in FIGS. 3 to 7 indicate the same or corresponding parts. Reference numeral 3 denotes a support stand arranged on the underside of the inner deck 2c and the outer deck 2d made of thin flat plates such as stainless steel plates with a single straight cross section, which is different from the conventional ones shown in FIGS. 5 to 7. They are also arranged in wide pitches. 5 and 5' are support rails disposed continuously in the longitudinal direction between the upper surface of this support platform 3 and the lower surface of the edge of each deck 2c and 2d,
For example, it is made of an extrusion molded product of a light alloy such as aluminum. Further, the support rail 5' is used by rotating the support rail 5 by 90 degrees within the plane shown in FIG. 2, and has a cross-sectional shape devised so that it can be made from the same molded product as the support rail 5. That is, the support rails 5, 5' have an inclined surface 6 that supports the inner deck 2c, a horizontal surface 7' that supports the outer deck 2d,
Mounting surfaces 8 and 9' to the support base 3 are provided, respectively, and spaces for tapping screws are secured on each of these surfaces 6, 7, 8, and 9. Furthermore, grooves 11 and 10', into which the lower ends of the packing 4 are fitted and locked, are continuously provided in the vertical surfaces 9 and 8' of the support rails 5 and 5' in the longitudinal direction.

These support rails 5, 5' are continuous bodies with a certain length (usually 2 to 3 m) in the longitudinal direction, and need to be shaped so as to follow the lower surface of each deck 2c, 2d of the curved escalator. Therefore, the overall shape is a spiral curve, and decks 2c, 2
The surfaces 6, 7' supporting d are manufactured by twisting the entire surface to become a spiral surface or an inclined spiral surface.

In the balustrade device configured as above,
The lower edge of the inner deck 2c is supported by the support rail 5.
Further, the lower edge surfaces of the outer deck 2d are continuously supported in the longitudinal direction by the support rails 5'. For this reason, even if the decks 2c and 2d are made of thin flat plates, there is no possibility of locally weak points occurring.

In the above embodiments, the parapet device for a curved escalator has been described, but it can be similarly applied to a straight escalator and a moving walkway.

In addition, in the above embodiment, the inner deck 2c and the outer deck 2
Although the case where both d and d are made of a thin flat plate has been described, the same can be applied to a case where only one of them is made of a thin flat plate.

〔Effect of the invention〕

As explained above, in this invention, a support rail for supporting and fixing the deck is arranged along the longitudinal direction between at least the lower edge of the thin flat deck on the side of the parapet body and the upper surface of the support base. The deck is supported by the support rail over its entire length, and there are no locally weak spots, which is preferable from the viewpoint of safety and design. In addition, local distortion of the upper surface of the deck due to assembly errors is less likely to occur.

Moreover, by disposing the support rails, the number of support stands can be reduced, thereby reducing costs and assembly time.

Furthermore, if the support rails for the inner deck and the outer deck are common, the support rails can be manufactured using one mold, and the investment in mold costs can be reduced. Also, if the support rail is provided with a groove in the longitudinal direction for inserting and locking the packing,
The packing is supported over its entire length, preventing it from sinking in or falling out locally.
