【Example】

Example 1. 1 to 3 are views showing an embodiment of the present invention, FIG. 1 is an elevation view showing an arrangement state of passenger conveyors installed in a void space of a building, and FIG. 2 is II-II of FIG.
FIG. 3 is an enlarged view of an essential part of FIG. In the figure, (1) is a building where both ends are the edges of the floor (8)
The main frame of the passenger conveyor supported by, (9) is a fixed body that is arranged in the building (8) and is made up of columns that are erected at the lateral positions of the longitudinal middle portion of the main frame (1). . (10) is a steady rest fastened to the side of the main frame (1) by a bolt (12) via a scissor plate (11) for adjustment, and (13) is fastened to the fixed body (9) by a bolt (14). As shown in FIG. 3, the receiving member is arranged to face the side surface of the steady rest 10 with a slight gap G therebetween.

In the intermediate steady rest device of the passenger conveyor configured as described above, the side face of the main frame (1) is a steady rest device.
It is arranged so as to face the fixed body (9) via the (10) and the receiving tool (13). Then, by inserting and adjusting the scissors plate (11) having an appropriate thickness between the main frame (1) and the steady rest (10),
A slight gap G is formed between the steady rest (10) and the receiver (13) by absorbing an installation error between the main frame (1) and the fixed body (9). Then, when a load such as passengers acts on the main frame (1), the main frame
Bending occurs in (1) and the longitudinal middle portion is displaced downward.

However, since a slight gap G is formed between the steady rest (10) and the receiver (13), even if the main frame (1) is bent and the longitudinal middle portion is displaced downward, The load due to the downward displacement of the main frame (1) does not act on the tool (13) and the fixed body (9). As a result, the fixed body (9) and the receiver (13) do not have to bear a large bending moment due to the load of passengers or the weight of the main frame (1), and the structure can be made lighter and thinner, and can be manufactured at low cost. be able to.

When the main frame (1) is pressed in the direction of the fixed body (9) in the event of an earthquake or due to the wind load blowing into the blow-through space of the building, the displacement of the main frame (1) in the fixed body (9) direction. Is restrained within the range of the gap G between the steady rest (10) and the receiver (13). In addition, since a slight gap G is formed between the steady rest (10) and the receiver (13), the main frame is bent due to the bending.
Even if (1) is displaced in the vertical direction, steady rest (10) and receiver
(13) are not displaced by rubbing against each other, and no unpleasant noise is generated. Also, the steady rest (10) and the receiver (13)
It is possible to prevent the abrasion caused by the mutual rubbing against each other.

Further, since there is no supporting member arranged below the longitudinal middle portion of the main frame (1), the installation restriction caused by the obstacle in the space above the passengers is eliminated because of the low floor, Other passenger conveyors arranged under the main frame (1) can be easily installed. Further, by making the fixed body (9) a columnar body as shown in FIG. 1, the main frame (1) is provided to each of the plurality of passenger conveyors vertically arranged in the building (8) by one columnar body. It is possible to suppress the displacement in the direction of the fixed body (9) in (4), obtain the above-mentioned respective actions, and reduce the construction cost.

Example 2. FIG. 4 is a view showing another embodiment of the present invention and corresponds to the above-mentioned FIG. In the figure,

(0) is a steady rest fastened to the side of the main frame (1) by a bolt (12) via a scissor plate (11) for adjustment, and (13) is a fixed body
The receiving member is fastened to the (9) by a bolt (14) and is arranged to face the side surface of the steady rest (10) as shown in FIG.

Reference numeral (15) is a sliding piece mounted on the surface of the steady rest (10) facing the receiver (13), which is made of a synthetic resin material having a low coefficient of friction. (16) is a receiver slide piece similar to the slide piece (15), and is mounted on the surface of the receiver (13) facing the steady rest (10) so as to face the slide piece (15). It is arranged.

In the intermediate steady rest device of the passenger conveyor configured as described above, the side face of the main frame (1) is a steady rest.
It is arranged so as to face the fixed body (9) via the (10) and the receiving tool (13). Then, so that the sliding piece (15) and the receiving piece sliding piece (16) come into light contact with each other, a scissor plate (11) of an appropriate thickness is provided between the main frame (1) and the steady rest (10). ) Is adjusted. Then, when a load such as passengers acts on the main frame (1), the main frame (1) is bent and the longitudinal middle portion is displaced downward.

However, since the slide piece (15) between the steady rest (10) and the receiver (13) and the slide piece for the receiver (16) are slidably displaced relative to each other, the main frame (1) is Even if it bends and the longitudinal middle portion is displaced downward, the load due to the downward displacement of the main frame (1) does not act on the receiver (13) and the fixed body (9). In addition, the main frame (1) is fixed by the wind load that blows into the void space of the building during an earthquake.
When pressed in the direction (9), the main frame is passed through the slide piece (15) of the steady rest (10) and the receiver (13) and the slide piece (16) of the receiver.

0) and the sliding piece (15) between the receiving piece (13) and the receiving piece sliding piece (16)
Are slidingly displaced with respect to each other. However, since the sliding piece (15) and the receiver sliding piece (16) are made of a low-friction material, it is possible to prevent the generation of unpleasant noise and wear during sliding displacement.

Further, since the anti-fixing body (9) side of the main frame (1) has a good view, when the passengers concentrate on the anti-fixing body (9) side of the main frame (1), the main frame ( Twist occurs in 1). However, since the sliding piece (15) and the receiver sliding piece (16) are always arranged in contact with each other, the sliding piece (15) is not affected by the torsional displacement of the main frame (1) at this time. ) And the receiver sliding piece (16) are contacted with each other, and the amount of twist can be reduced. Also,
Since the sliding piece (15) and the receiving piece sliding piece (16) are always arranged so as to be in contact with each other, the sliding decorative piece (10) and the receiving piece (13) of the exterior decorative member provided to cover the steadying piece (10) The structure can be simplified and the manufacturing cost can be reduced.

It is adjusted by inserting a scissor plate (11) having an appropriate thickness between 0). Then, when a load such as passengers acts on the main frame (1), the main frame (1) is bent and the longitudinal middle portion is displaced downward.

However, since the slide piece (15) between the steady rest (10) and the receiver (13) and the receiver slide piece (16) are slidably displaced relative to each other, the main frame (1) is Even if it bends and the longitudinal middle portion is displaced downward, the load due to the downward displacement of the main frame (1) does not act on the receiver (13) and the fixed body (9). In addition, when the main frame (1) is pressed toward the fixed body (9) due to an earthquake or wind load blown into the void of the building, the main frame (1) is pushed through the steady rest (10) and the receiver (13). The displacement of the frame (1) toward the fixed body (9) is suppressed.

Further, the steady rest (10) and the receiver (13) are connected to each other via the excessive displacement prevention means (171). Further, in the embodiment of FIG. 8, the steady rest (10) and the receiver (1
Since 3) are arranged to face each other with one sliding piece (15) and one receiving piece sliding piece (16), only one facing surface is provided.
Therefore, although detailed description is omitted, it is obvious that the embodiment of FIG. 8 can also obtain the same operation as the embodiment of FIG. 4, the embodiment of FIG. 6, and the embodiment of FIG.
