DESCRIPTION:
BRIEF SUMMARY
The invention relates to a floor-sweeping machine consisting of a housing with a revolving brush which is mounted rotatably therein and is driven by running wheels and which is located between two dirt-collecting spaces, the two dirt-collecting spaces being formed by dirt-collecting containers which can be taken out of the housing upwards, and the dirt-collecting container having a resilient locking device which secures it in its operating position and which can be transferred by hand to its release position.
In this floor-sweeping machine, when it is used as intended, the dirt is swept, by the revolving brush driven by running wheels, into the particular dirt-collecting space located at the front in the direction of movement. Therefore, as seen by the operator, one dirt-collecting space is located in front of the revolving brush and one dirt-collecting space is located behind the revolving brush. Thus, each dirt-collecting space is formed by a separate dirt-collecting container which can be taken out of the housing upwards by itself. To empty the dirt-collecting containers, the operator must therefore take the two dirt-collecting containers out of the housing of the floor-sweeping machine individually and empty them. To take each dirt-collecting container out of the housing of the floor-sweeping machine, the operator has to loosen two resilient locking devices provided on opposite sides of the dirt-collecting container. It is consequently very complicated to take out the dirt-collecting containers and empty them.
To make it easier to take out the separate dirt-collecting containers, therefore, the locking devices have already been connected to one another by means of a clip which spans the dirt-collecting container, so as to transfer the two locking devices into the release position by pulling up this clip. However, the surface of the dirt-collecting container is impaired and the space required increased by the use of this clip engaging over the dirt-collecting containers.
The object on which the invention is based is to provide a floor-sweeping machine of the type explained in the introduction, in which such disadvantages are avoided and it is made substantially easier to operate it and especially to take out and empty the dirt-collecting containers.
This object is achieved, according to the invention, due to the fact that the two dirt-collecting containers are connected to one another and have a common top side in which there is, approximately in the centre, a part which is to be grasped by the operator and is to be moved to a limited extent in the lifting-out direction and which, when moved in the lifting-out direction, transfers the resilient locking device into the release position. By combining the two dirt-collecting containers into a constructional unit, the operator can, in a simple way, take the dirt-collecting containers out of the housing of the floor-sweeping machine together in one operation and empty them. At the same time, it is especially simple to take out and insert the two combined dirt-collecting containers.
A recess can be shaped in the common top side of the two dirt-collecting containers connected to one another, and located in this recess is a pivoting lever which covers the recess with the exception of an engagement orifice and which forms the part movable in the lifting-out direction. The part movable in the lifting-out direction is thus formed by a pivoting lever which is provided in a recess in the top side of the dirt-collecting container, so that, in the operating position, the pivoting lever does not project above the top side of the dirt-collecting container.
The pivoting lever can have an approximately U-shaped design, the crown part of which is made plate-shaped and covers the recess with the exception of an engagement orifice and is to be gripped underneath with the operator's fingertips, whilst the two legs of the approximately U-shaped pivoting lever engage through the upper wall of the dirt-collecting container and are mounted pivotably about a horizontal axle on the
