Abstract

The endless escalator handrail is made up of a thermoplastic resin member having a first and a second curved portions and a joint section; a flat woven fabric bonded to an inner surface of the thermoplastic resin member; a first patch cloth having a base portion and a divergent portion, for being placed on the first curved portion side in the joint section; and a second patch cloth having a base portion and a divergent portion, for being placed on the second curved portion side in the joint section. The divergent potion of the first patch cloth is bonded onto the flat woven fabric at an inward side of the first curved portion, and the divergent potion of the second patch cloth is bonded onto the flat woven fabric at an inward side of the second curved portion.

First claim

The invention claimed is:

1. An endless escalator-handrail comprising:
a thermoplastic resin member having a first and a second curved portions formed oppositely on both lateral sides of a flat portion of the member, and joined at a joint section by melting cut ends of the member;
a flat woven fabric bonded to an inner surface of the thermoplastic resin member to cover the flat portion and the first and the second curved portions;
a first patch cloth having a base portion and a divergent portion, for being placed on a first curved portion side in the joint section; and
a second patch cloth having a base portion and a divergent portion, for being placed on a second curved portion side in the joint section, wherein

the divergent potion of the first patch cloth is bonded onto the flat woven fabric at an inward side of the first curved portion, and the divergent potion of the second patch cloth is bonded onto the flat woven fabric at an inward side of the second curved portion.

2. The endless escalator-handrail of claim 1 , wherein the base portions of the first and the second patch cloths are bonded onto the flat woven fabric at the flat portion of the thermoplastic resin member.

3. The endless escalator-handrail of claim 2 , wherein the divergent portions of the first and the second patch cloths each have an acute angle corner, and the acute angle corner being formed in a round shape chamfer.

4. An escalator comprising:
a drive machine installed in a machine room;
steps connected in a loop and ascending/descending by the rotation of the drive machine; and
an endless escalator-handrail of claim 1 , turning around in synchronism with the ascending/descending of the steps.

5. An endless escalator-handrail comprising:
a thermoplastic resin member having a first and a second curved portions formed oppositely on both lateral sides of a flat portion of the member, and joined at a joint section by melting cut ends of the member;
a flat woven fabric bonded to an inner surface of the thermoplastic resin member to cover the flat portion and the first and the second curved portions;
a first patch cloth having a quadrilateral shape whose opposite lateral sides are inclined in the same direction, for being placed on a first curved portion side in the joint section; and
a second patch cloth having a quadrilateral shape whose opposite lateral sides are inclined in the same direction, for being placed on a second curved portion side in the joint section, wherein

the first patch cloth is bonded onto the flat woven fabric at an inward side of the first curved portion, and the second patch cloth is bonded onto the flat woven fabric at an inward side of the second curved portion.

6. The endless escalator-handrail of claim 5 , wherein the first and the second quadrilateral patch cloths each have an acute angle corner, and the acute angle corner being formed in a round shape chamfer.

7. An escalator comprising:
a drive machine installed in a machine room;
steps connected in a loop and ascending/descending by the rotation of the drive machine; and
an endless escalator-handrail of claim 5 , turning around in synchronism with the ascending/descending of the steps.
