[Problems to be solved by the device]

  The conventional moving sidewalk device shown in FIG. 9 has a moving handrail side and a tread side which are different from each other. Since it is driven by the drive source, it is difficult to synchronize the movements of both. Move the handrail side In order to drive the handrail without slipping, do not bend the rotating part of the handrail. It is necessary to provide appropriate tension applying means, and a large resistance is generated at this bent portion. On the other hand, driving resistance must be increased and driving force must be increased. Railing side and tread Since the belt side is separated, a return roller and a support roller are required for each. However, there is a problem that the overall shape is high and elongated.

[0005]   The device disclosed in the above-mentioned Japanese Patent Laid-Open No. 2-276792 is a drive device for a moving handrail. Since the force is taken from the operation on the step side, it is effective in terms of synchronized movement, but It is not driven directly from the drive source, Driven by the frictional force between the traction roller and the handrail And between the traction roller and the driven link of the step. Especially transfer The moving handrail side receives driving force on the surface of the handrail, and the surface of the handrail is a moving sidewalk. Slip is liable to occur if the passenger's hands get dirty with oil or if they are rubbed with their hands or luggage. Become If you try to increase the frictional force during this time, the handrail will be There is a drawback that it bends like a bellows between the roller and the pressing roller on the back side of the handrail and the life is shortened. is there.

[0006]   The present invention solves the above-mentioned problems and reliably synchronizes the movement of the tread and the movement of the moving handrail. The handrail can be slid without applying special tension to the moving handrail. The risk of popping up is small, thus the life of the handrail is long and the overall bulkiness is high. It is to provide a moving walkway device that can be lowered.

[0007]

【Example】

  Next, embodiments of the present invention will be described with reference to the drawings. Figure 1 Implementation of the present invention FIG. 2 is a schematic side view of an example moving walkway device, FIG. 2 taken along line AA of FIG. 1. It is a partial front sectional view. The endless tread belt 4 on which a person rides is driven by the drive pulley 3a. And the driven pulley 3b, and is connected to the drive pulley 3a via the chain 2. The motor 1 is rotated to rotate. The upper rotating part of the tread belt 4 is attached to the device fixing part. It is supported by a plurality of support rollers 8 which are axially supported. Both edges of tread belt 4 On the outer surface adjacent to the section The part 5 is fixed all around. Move to enclose this tread belt 4 A rail 6 is rotatably endlessly laid between a pair of pulleys 10a and 10b. , The lower surface (outer surface) of the lower rotation part (return side of the tread belt) supports a plurality of The upper rotating part of the handrail 6 is supported by rollers 7 and is mounted as shown in FIG. It is supported by the tip of the plate-shaped handrail guide 11 held by the mounting and fixing part so that it can slide. It has become. In this embodiment, the rear surface of the lower rotating portion of the moving handrail 6 is provided with the tread belt 4 It is in contact with the rubber convex portion 5 on the outer surface of the lower rotating portion. Therefore, the lower rotation of the moving handrail 6 As shown in FIG. 2, the parts are a support roller 7 and a tread belt 4 which are axially supported by the device fixing part. The lower rotation portion of the tread belt 4 is sandwiched between the lower rotation portion and the rubber convex portion 5. It is pressed against the lower support roller 7 via the rubber convex portion 5 by its own weight. This The lower rotating part of the moving handrail 6 is pinched between the rubber convex part 5 and the support roller 7 as shown in FIG. As a result, when the tread belt 4 rotates, the moving handrail 6 causes friction with the rubber convex portion 5. The force causes the tread belt 4 to rotate in the same direction and at the same speed. The rubber protrusion 5 is a tread bell It is affixed to the cover 4 or is formed integrally therewith. Move with rubber protrusion 5 In order to more securely engage the lower rotating portion of the handrail 6 and to eliminate slip, As shown in Fig. 5, serrated irregularities 17 are formed on the front surface of the rubber convex portion 5 and the rear surface of the moving handrail. May be formed so as to be in tooth surface engagement with each other. In the embodiment shown in FIGS. The lower rotating part of the roller 6 is pressed by the rubber protrusion 5 on the tread belt side and the support roller 7 to rotate. The tread belt belt 4 does not slip even if tension is applied to the handrail so that it can be held securely. Since it can rotate in synchronism with the above, the running resistance is small and the life of the moving handrail is extended. Step on again Since the plate belt 4 completely enters the inside of the moving handrail, the overall height is smaller than that of the conventional one. The lower, lower support roller 7 supports both the tread belt 4 and the moving handrail. Therefore, the number of supporting rollers is small.

[0009]   4 to 8 show another embodiment of the present invention. As shown in FIG. The upper belt support roller 8 is laid between the moving pulley 3a and a driven pulley (not shown). , The tread belt 4 supported by the lower belt support roller 15 and the snubb pulley 12 The lower rotating portion of the endless moving handrail 6 is arranged adjacent to the outer side portion of the. Transfer The moving handrail 6 is guided by a rail-shaped handrail guide 13 fixed to the device fixing portion. It slides on the guide 13. Is the handrail guide 13 an upper rotation part of the moving handrail 6? To the lower rotation part through the bent-back parts at both ends in the longitudinal direction of the handrail. Has been extended to. Does the handrail guide 13 reach the lower rotating part of the moving handrail 6? The outer surface of the guide gradually becomes closer to the end of the guide as shown in FIG. Biased to face outward. In FIG. 7, 18 extends from the device fixing portion. It is a handrail guide mounting bracket. The back side of the handrail 6 with a C-shaped cross section Comes into contact with the handrail guide 13, and from the vicinity of the end of the guide 13, the back surface of the handrail is The handrail guide 13 is twisted by 90 ° so as to face the side edge of the lower rotating portion of the belt 4. After the end of the rail, the back surface of the handrail is engaged with the side edge of the lower rotating portion of the tread belt 4. It has become. Note that due to the weight of the handrail 6, the C-shaped upper flange portion of the handrail has a tread plate. It is caught on the upper surface of the side edge of the belt 4 (see Fig. 6), which causes the moving handrail 6 to step on it. It does not fall off the plate belt 4. Contact area between moving handrail 6 and tread belt 4 The outer surface of the moving handrail 6 twisted 90 ° is pressed against the outer edge of the belt. Of the pressure roller 14 is axially supported by the device fixing portion, and the pressure roller 14 and the device fixing portion are A leaf spring 19 for pressing the roller 14 is provided between and. Press The shaft portion of the roller 14 is supported by being inserted into a long hole-shaped bearing portion of the device fixing portion. Be done. Therefore, the lower rotating portion of the moving handrail 6 is caused by the pressing spring 19 to move the tread bell. The handrail is pinched between the belt 4 and the pressing roller 14 and is moved by the rotation of the tread belt 4. 6 rotates in the same direction and at the same speed as the tread belt 4. In FIG. 6, the tread belt 4 The upper rotation part of the is a side guide roller that is axially supported from the device fixing part via a bracket. 20 prevents lateral meandering.

[0010]   Also in the embodiment of FIGS. 4 to 6, rubber convex portions are fixed to both side edges of the tread belt 4, A friction member such as canvas attached to the back surface of the moving handrail 6 is pressed against the rubber convex portion to make it large. Different frictional forces may be generated. Depending on the case, as shown in FIG. Saw-tooth-like irregularities 17 are formed on the side edges of the grate 4 and the back surface of the moving handrail 6 to form tooth surfaces So that the slip of the engaging portion between the tread belt 4 and the moving handrail 6 is caused. It may be possible to eliminate the gap. In this embodiment, the tread belt belt is used to clamp the moving handrail. Instead of the self-weight, the pressure roller 14 using the leaf spring 19 positively presses. Ensures a secure engagement without slipping, and can be used even when the tension of the moving handrail is small. The moving handrail can be rotated in synchronization with the plate belt 4. Implementation of FIGS. 4 to 6 In the example, the balustrade is simplified because no winding pulley for the handrail is required.
