Japanese Utility Model Publication No. 55-160378

Next, problems of the conventional handrail entrance / exit device for a man conveyor configured as described above will be described.
When a child's hand or finger is caught in the gap 22 between the inlet rubber 9 and the rubber handrail 4 due to mischief or the like, the inlet rubber 9 is pushed in the direction of arrow A in FIG. The micro switch 17 is operated to stop the man conveyor. A sliding piece 21 is attached to the upper side portion of the inlet rubber 9 so that the sliding with the support metal fitting 19 is smooth and the operation of the micro switch 17 is ensured. The attachment of the inlet rubber 9 is adjusted so that the gap 22 between the rubber handrail 4 and the inlet rubber 9 is uniform, and the gap 22 is normally 2 to 4 mm. This gap 22 is set in consideration of some misalignment between the upper and lower sides and the left and right sides of the rubber handrail 4 depending on the hand and fingers of the child and the operating direction of the man conveyor.
If the gap 22 is too wide, it will be easy for children's hands and fingers to enter, impeding safety. If the gap 22 is too narrow, the inlet rubber 9 and the rubber handrail 4 will come into contact when the operation direction of the man conveyor is switched. When the micro switch 17 is activated, the man conveyor is stopped, and a user who is on the man conveyor may fall down. Therefore, this gap adjustment is an important installation / assembly item and also a maintenance item.
Next, a method of attaching the inlet rubber 9 will be described with reference to FIGS.
The handrail entrance 9 made of inlet rubber or the like is manufactured by a molding die and has the same shape for each product. Since the inlet rubber 9 is supported by the support fitting 19, the gap 22 is adjusted by the support fitting 19. 9 and 10 show a state where the inlet rubber 9 is removed. The support bracket 19 is temporarily attached to the balustrade frame 5 before attaching the rubber handrail 4 to the balustrade frame 5. Next, the rubber handrail 4 is fitted into the balustrade frame 5. The support bracket 19 is attached with a dimension B with the upper surface portion of the rubber handrail 4. This dimension B is performed at two locations on the front skirt 8 side and the front end side. The insertion part of the screw 20 of the support metal 19 is a long hole 23 for adjustment. The mounting of the support bracket 19 on the front side in the figure is relatively easy, but adjustment of the dimension B is very difficult because the outside (wall side) has a narrow building wall 18 made of concrete. In particular, it is difficult to work near the front skirt 8, and it takes a lot of time to tighten and loosen the screw 20 many times.

  The present invention has been made to solve the above-described problems. By eliminating the adjustment of the gap between the handrail inlet / outlet made of inlet rubber or the like and the rubber handrail, workability can be remarkably improved. A handrail doorway device for a conveyor is provided.

In the handrail entrance / exit device for the man conveyor according to the present invention, an inlet rubber is provided at the handrail entrance / exit portion of the man conveyor, and a clearance adjustment between the inlet rubber and the handrail is attached to a balustrade frame for supporting metal fittings supporting the inlet rubber. In order to fix the support bracket to the center portion, the height between both ends is the same as the height of the support bracket and the top surface of the handrail. A handrail entrance / exit attachment jig that is substantially U-shaped so that the fastener can be inserted, loosen the fastener a little, temporarily attach the support bracket to the balustrade frame, and the bottom surface of the handrail entrance / exit attachment jig in a state in which the support fitting is placed on the upper surface portion of the handrail positioned, and mounting the support bracket for supporting the inlet rubber on both end portions of the handrail entrance mounting jig and a fastener It is for fixing the support bracket to the railing frame with fit.

  According to the present invention, the handrail entrance / exit mounting jig is placed on the upper part of the handrail where the support fitting for supporting the handrail entrance made of inlet rubber or the like is located, and the support fitting is placed on the jig to depend on the dimensions. Since the gap adjustment is eliminated, there is an effect that workability can be remarkably improved.
