DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work gondola used for cleaning windows of buildings such as buildings.

[0002]

2. Description of the Related Art Conventionally, a working gondola of this type has a pair of left and right ropes suspended from a pair of gondola support arms fixed by the inventor of the present invention at portions near both upper ends of a building such as a building. A structure in which a gondola body on which a worker can ride is moved up and down and left and right by expanding and contracting each with a winch has been considered.

[0003]

A conventional work gondola capable of moving the main body of the gondola up, down, left and right has a guide member for guiding left and right ropes at an upper part of the main body of the gondola. When the main body is moved right and left, the gondola main body is inclined by the pulling force of the right and left ropes, and there is a drawback that the window glass cannot be safely cleaned.

The present invention has been made in view of the above-mentioned conventional drawbacks,
Even if the gondola body is moved in the left-right direction, the gondola body is always in the vertical position, and the window glass can be cleaned safely and efficiently, and the structure is simple and the manufacturing cost is low. It aims to provide a working gondola.

The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings. However, the drawings are for explanation only, and do not limit the scope of the present invention.

[0006]

In order to achieve the above object, the present invention provides a pair of gondola support arms fixed to a part near the upper end of a building such as a building or a part several meters away from the building. The left and right ropes suspended from the gondola support arm, and workers who can expand and contract the length of the left and right ropes and move vertically and horizontally to clean window glass etc. A work gondola comprising a work gondola main body, a gondola frame on which an operator can ride the work gondola main body, and a front end rotatably attached to a substantially central portion of the gondola frame so as to be rotatable left and right. A movable arm having a pair of guide rollers mounted thereon for guiding the left and right ropes in a crossing manner, Side guide rollers for guiding the left and right ropes from the pair of guide rollers of the movable arm attached to both sides downward, and the left and right ropes from the side guide rollers attached to the gondola frame expand and contract, respectively. A work gondola is constituted by a pair of rope vertical movement devices such as an electric winch and a winder that can be used.

[0007]

The work gondola constructed as described above operates the pair of rope up and down moving devices to extend and contract the left and right ropes in the same manner, whereby the body of the work gondola moves vertically. Also, by extending and contracting the left and right ropes so that the lengths are different, the work gondola body moves in the left and right direction. At this time, since the movable arm on which the pair of guide rollers is mounted rotates in the left-right direction, the gondola frame on which the operator is riding is always in a vertical state.
