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 or maintaining window glass of a building such as a building, especially a building having an eaves ceiling.

[0002]

2. Description of the Related Art Conventionally, a work gondola of this type has a gondola support installed on the roof of a building such as a building by means of guide members attached to the center of both sides of a gondola body on which an operator can ride and work. It is configured to guide a pair of ropes suspended from the tip of the arm.

[0003]

In the conventional work gondola, the gondola main body is suspended by a pair of ropes via guide members attached to substantially central portions on both sides of the gondola main body. In the case of a building such as an own building, there is a drawback that a worker who gets into the gondola body cannot access the window glass due to the eaves ceiling and cannot clean the window glass.

The present invention has been made in view of the above-mentioned conventional drawbacks,
It is an object of the present invention to provide a work gondola that allows a worker who rides on a worker support frame of a gondola body to safely and easily perform cleaning work on window glass even in a building such as a building having an eaves ceiling.

The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in view of 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 gondola main body which allows an operator to ride on the window glass of a building such as a building to perform cleaning work and maintenance work. In a work gondola including a pair of ropes suspended from the tip of a pair of gondola support arms installed on the roof of a building such as the building where the body can be suspended, an operator rides the gondola body. An operator support frame that can be used for cleaning and maintenance work, a drive device for the pair of ropes attached to the rear of the operator support frame, and a weight for balancing the operator support frame. A support frame such as a drive device fixedly or movably attached, and a support frame for the drive device and the worker support frame; Work capable of always keeping the worker support frame horizontal with a guide member that guides the pair of ropes interposed in the drive device that is attached to the connection portion near the side or in the vicinity of the connection portion. Make up a gondola for.

[0007]

With the work gondola configured as described above, the operator support frame of the gondola body is located in front of the pair of ropes, and the operator support frame is supported even if the window glass is located at the part retracted by the eaves ceiling. The frame can be positioned at the retracted position, and the gondola body can be positioned in a stable horizontal state by the drive device and the weight of the support frame such as the drive device, so that the worker can safely perform the work.
