Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to passenger conveyors such as escalators and electric roads, and is particularly suitable for improving workability and safety in assembling handrails using glass panels. Regarding the 1st composition.

[Conventional technology]

Passenger conveyors such as escalators are required to have improved design and ease of assembly, as well as to ensure passenger safety, in response to the trend toward fashionable building interiors and shorter construction periods. The configuration of recent passenger conveyors is disclosed in Japanese Patent Application Laid-Open No. 61-1869.
Although this example is disclosed in Japanese Patent No. 2, there is room for improvement in terms of ease of assembly and safety as described above.

[Problem that the invention seeks to solve]

In the conventional example described above, steps 1. It also consists of a moving part consisting of a moving handrail 2, and stationary bodies such as a handrail 3 and a main body frame 4, all of which are supported under the floor of the building. The details of the balustrade 3 are the transparent glass panel 5
A plurality of pieces are arranged parallel to the movement direction of step 1 in the entire length direction of the handrail 3, and a deck cover 6 is attached to the lower side of the railing, and a guide frame 7 is fixed with adhesive (adhesive 8) to the upper side of the handrail 3 to move the moving handrail 2. Guidance is on point. Note that the glass panel 5 is erected while adjusting the gap (δ) in the entire length direction of the parapet, and the guide frame 7 is installed with the gap L
b (r, b>δ) so as not to interfere with each other, and the joint plate 9 is fixed to the guide frame 7 with screws 10 at the joint portion. This joint plate 9 prevents the glass panel 5 from shifting laterally (indicated by the symbol Y in FIG. 4), and there is also an example in which the outer periphery of the guide frame 7 is covered with a guide 11 made of synthetic resin.

The conventional example shown here uses a joint plate 9 and screws 10 at the joint between the glass panel 5 and the guide frame 7, which has the disadvantage that the assembly work is complicated. That is, since the amount of the gap δ depends on the adjustment work, the position of the screw 10 in the longitudinal direction is not determined, and it is necessary to machine a screw hole for each unit of the glass panel 5. Therefore, even if the design is improved by making the guide frame 7 smaller (normally, the amount exposed from the movable handrail 2 as indicated by reference numeral 2 in Fig. 4 spoils the aesthetic appearance), it will be a bottleneck in terms of assembly work. Become.

On the other hand, in the example shown in FIG. 5, since there is a gap Lb between the guide frames 4, it is conceivable that the passenger's fingers may come into contact with the lower corner M of the gap Lb and be injured.

This is because the lower side of the guide frame 7 is exposed on the lower surface of the movable handrail 2, and passengers who bring their hands close to this area may be injured.

An object of the present invention is to provide a handrail for a passenger conveyor with excellent assembly ease and safety.6 [Means for solving the problems] This is achieved by providing a joint material between the guide frame having the same cross-sectional shape as the guide frame, and whose long sides are trapezoidal in shape.

[Effect]

The joint plate has the same shape as the guide frame, especially its lower side has the same plane when connected to the guide frame, and its longitudinal shape is a trapezoid with a short upper side and a long lower side. It is a shape that only needs to be removed (ground) by the length of the bottom side. This eliminates corners and simplifies assembly work.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, the glass panel 5° deck cover 6, guide frame 7, etc. have approximately the same structure as the conventional one, but in the joint structure of the glass panel 5 of the present invention, the gap L5 between the guide frame 7 The feature is that the joint material 12 is provided with a length Lh that is slightly longer than the length Lh. here,
Like the guide frame 7, the joint material 12 has grooves and protrusions, and is adapted to fit with the upper edge of the glass panel 5 and guide and support the moving handrail 2, and its longitudinal shape is trapezoidal. ing. And the interval between the guide frames 7 is Lh
If so, only Lh-Lb are matched and deleted. This amount of deletion is shown by cross-hatching in Figure 2.
For example, the amount of deletion in the height direction is reduced by hh compared to the case where the length is simply Lh instead of a trapezoid. After completing this deletion, as shown by the arrow P, it is fitted onto the upper edge of the glass panel 5 and glued, and attached as shown by the imaginary line R.

By doing this, during assembly work, the glass panels 5 can be connected by only removing a small portion of the joint material 12, and the conventional dangerous corner M is also eliminated, resulting in a flat lower side. is obtained.

〔Effect of the invention〕

According to the present invention, the assemblability and safety of the handrail of the passenger conveyor are improved.
