Title:
OPERATION BOX DOOR OF WINDOW OPENING-CLOSING DEVICE
Document Type and Number:
Japanese Patent JP2002081256
Kind Code:
A
Abstract:

To cope with either left or right opening direction even if two machine models are not manufactured on a door conveniently openable in the left direction and the right direction and even if a double hinged structure such as a special hinge mechanism (a slide hinge) is not used in an operation box door of a window opening-closing device.

A face unit 4 is constituted to be rearrangeable in an opening part 1a of an operation box 1 by vertically reversing by superposing a face 2 and a base frame 3 of a vertically and laterally almost symmetrical shape. Thus, the opening-closing direction of the face 2 can be laterally quickly and easily changed only by vertically reversely rearranging the face unit 4 of a single machine model at an execution work site. The machine model is formed for general purpose, and a burden of maintenance/control is reduced. A structure is simple and cost-effective differently from arranging the complicated double hinged structure.
