Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement of a handrail support and guide device for a passenger conveyor that supports and guides a handrail using a parapet panel.

[Prior art]

As shown in FIGS. 1 and 2, the conventional handrail support and guide device has a notch 1a at the upper end of a balustrade panel 1 made of transparent tempered glass, etc., and a notch 2a provided in a U-shaped packing 2 and the balustrade. A gasket 2 is placed on the upper end of the balustrade panel 1 so that the notch 1a of the panel 1 faces, and a guide frame 3 having a U-groove 3a is fitted onto the gasket 2,
After inserting the screws 4 into the notches 1a and 2a and securely fastening the balustrade panel 1 and the guide frame 3 with the nuts 5, the guide 6 is fitted into the groove 3b provided above the guide frame 3. be done.

[Problems to be Solved by the Invention] However, in such a conventional handrail support and guide device, notches for screwing must be provided at the upper end of the balustrade panel, which prevents damage to the balustrade panel due to over-tightening of the screws. Due to this, the efficiency of assembly work is extremely low. 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. It's a moyatsu user.

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.

[Means for solving problems]

The present invention provides a cushioning material for a first groove having an opening facing downward and the upper edge of a balustrade panel, which is formed of a thin plate formed to have grooves having openings facing upward and downward, respectively. a second groove having an opening facing upwardly in the frame located on the left and right sides of the balustrade panel;
The parapet panel and the frame are constructed integrally by inserting a box-like cross-sectional member with one side open and the inside slightly wider.

[Effect]

With the configuration as described above, the balustrade panel and the frame can be reliably connected at the open end of the box-shaped cross-sectional member without being affected by the reaction force from the corner of the frame.

[Example] An example of the present invention will be described below with reference to the drawings.

FIG. 3 is a sectional view of a handrail support and guide device showing an embodiment of the present invention, in which reference numeral 11 indicates a handrail panel made of transparent tempered glass, etc., and 12 indicates grooves having openings facing upward and downward. A frame made of a thin plate of stainless steel or the like formed to have a first groove and a first groove having an opening toward the bottom of the frame 12 so as to cover the upper end of the balustrade panel 11 with a cushioning material 13 interposed therebetween. The upper end of 11 is loosely fitted. Reference numeral 14 is a short member made of, for example, extruded aluminum material, which has a box-shaped cross section with one side open and the inside slightly wider. The member 14 is fitted and the balustrade panel 11 and the frame 12 are integrally constituted by the member 14.
Since this member 14 reliably sandwiches the frame 12 at the open end a, the connection is extremely strong. 15 is a gap for releasing the reaction force from the corner b of the frame 12 when the member 14 is attached;
6 is a guide rail made of, for example, synthetic resin, which directly supports and guides the handrail 7;
It is installed by inserting it sequentially into both ends of 2. 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). .

〔Effect of the invention〕

With the configuration described above, there is no need to provide notches 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, cushioning material can be added to the top end of the balustrade panel in advance. After passing through the open end a
Since the wider member 14 is fitted into the second groove that has an opening facing upward of the frame 12, the parapet panel and frame are integrally constructed so that the cushioning material does not protrude and impair the design. It is possible to obtain a handrail support and guide device that has become more durable.

Furthermore, with the support and guide device according to the present invention, the size of the frame can be changed as shown in FIG. 4, and the frame can be made to protrude from the lower surface of the handrail as appropriate to give a different design.
