Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a handrail support and guide device for man-con hair, which uses a handrail panel to support and guide the handrail.

As shown in FIGS. 1 and 2, the conventional handrail support and guide device has a notch 1a in the upper end of a handrail panel 1 made of transparent tempered glass or the like, and a notch 2a in a U-shaped packing 2. Cover the upper end of the balustrade panel 1 with the gasket 2 so that the notch 1a of the balustrade panel 1 faces, and fit the guide frame 3 having the U groove 3a over it,
After inserting the screws 4 into the notches la and 2a and firmly fastening the balustrade panel 1 and the guide frame 3 with the nuts 5, fit the guide 6 into the groove 3b provided above the guide frame 3. configured.

In such a conventional handrail support and guide device, notches for screwing must be provided at the upper end of the balustrade panel, and there is a risk of damage to the balustrade panel due to over-tightening of the screws, resulting in extremely poor assembly efficiency. Furthermore, in order to construct a handrail support and guide device with excellent design by installing the guide frame 3 within the inner periphery of the handrail 7 in a limited space, extremely small screws must be used, making handling difficult. They are also a pair.

The present invention has been made in view of this point, and it is an object of the present invention to provide a handrail support and guide device for a passenger conveyor that can be easily and reliably assembled and has an extremely compact overall structure.

FIG. 3 is a cross-sectional view of a handrail support and guide device showing an embodiment of the present invention. In the figure, numeral 11 indicates a handrail panel made of transparent tempered glass, etc., and numeral 12 indicates a handrail panel formed so as to have grooves on the upper and lower sides, respectively. The frame is made of a thin plate of stainless steel or the like, and the upper end of the balustrade panel 11 is loosely fitted into the lower groove of the frame 12 so as to cover the upper end of the balustrade panel 11 with a cushioning material 13 in between. Reference numeral 14 is a short member made of extruded aluminum or the like, which has a box-shaped cross section with one side open and the inside slightly wider. This member 14
The balustrade panel 11 and the frame 12 are integrally constructed by the member 14. This member 14 reliably clamps the frame 12 at the open end a, so that the connection is extremely strong. 15 is a gap for releasing the reaction force from the corner of the frame 12 when the member 14 is installed; 1
Reference numeral 6 denotes a guide rail made of, for example, synthetic resin, which directly supports and guides the handrail 7, and is sequentially inserted and attached to both ends of the frame 12. 17 is a gap to facilitate insertion of the guide rail 16 into the frame 12, and 18 is a gap to reduce contact resistance between the hand rail 7 and the guide rail 16, which rotate in synchronization with a step (not shown). .

With the configuration described above, there is no need to provide a notch for screwing at the top end of the balustrade panel, and even if there is a manufacturing error or molding error in the balustrade panel or frame, there is no need to make a cut in the top end of the balustrade panel. Since the member 14, whose interior is wider than the open end a, is inserted into the groove above the frame 12 through the cylindrical material, the cushioning material does not protrude and impair the design of the balustrade panel. It is possible to obtain a hand rail support and guide device in which the frame and frame are integrated.

In addition, with the support and guide device according to the present invention, it is possible to change the size of the frame as shown in FIG. 4, and to make the frame protrude from the lower surface of the handrail as appropriate to bring about a change in design.

Claims (1)

[Scope of Claims] The upper edge of the balustrade panel is loosely fitted into the lower groove of a frame made of a thin plate formed to have grooves on the upper and lower sides, via a cushioning material, wherein the left and right sides of the balustrade panel A member having a box-shaped cross section with one side open and the inside being slightly wider is fitted into a groove above the frame located at the top of the frame, so that the parapet panel is integrated with the frame. A handrail support and guide device for passenger conveyors.
