Device for adjusting the height of the brush roller on sweepers, especially carpet sweepers

The innovation relates to sweepers, especially carpet sweepers with several running across the floor Wheels and a roller brush that conveys the rubbish into suitable containers, such as dustpans.

It is already known to adjust the vertical position of the brush roller to adapt to different heights of To make carpets and smooth floors. The well-known facilities for this purpose, however, are because of their complexity and cost as well as difficulty disadvantageous for repairs.

7602618 02.0976

In a known device, for example, a rotary cam used, which is connected to the zenlagerung Bürstenwal zenlagerung via a transmission. This transmission or translation converts the rotary movement into a linear vertical movement of the brush roller bearing and thus inevitably contains a large number of fasteners. Such translations are known from DT-PS 1,814,730, for example.

The object of the present innovation is to create a sweeping machine that can be operated in particular by hand, preferably a carpet sweeper provided with a roller brush with a vertical adjustment device, wherein however, the need for a complex translation between the manual control device and the brush mounting avoided is. Veiter, the invention is aimed at simplification the adjustment device and to a reduction in its cost and complexity of its structure.

According to the innovation, a linearly movable actuator is provided, the movement of which changes directly into a linear one Movement of the brush roller bearing is implemented.

According to a further feature of the innovation, the linear movement of the actuating member takes place in the plane of actuation the sweeper, i.e. generally horizontally. This horizontal movement is then transformed into a linear movement of the Brush mounting implemented, which is perpendicular to the working plane of the sweeper, i.e. generally vertical.

The result is a much simpler construction that also has significantly fewer operating errors is exposed.

7602618 02.09.76

The innovation is based on a device for height adjustment the brush roller on road sweepers, in particular Carpet sweepers, in which the brush roller sweeping across the floor is located in one between the side walls of the sweeping machine Chinenrahmens extending, relative to the sweeper frame is mounted in the height adjustable cross member, and is characterized in that between the cross member and a cover part of the frame in a straight line in the transverse direction Slidable slide is arranged to the frame, which via cam members arranged on it with the cross member seated cam members interacts and thereby the displacement movement of the slide in a height adjustment of the cross member transformed relative to the frame.

Further developments of the innovation are given in the subclaims.

The drawings show in

Fig. 2 is a partial exploded perspective view the height adjustment device;

Fig. 3 is a bottom view of the sweeper with removed

Refuse collection shovels and some broken ones. Divide;

Fig. 4 shows a cross section along the line IV-IV of Fig. 3;

FIG. 5 shows a representation similar to FIG. 4 for reproducing the brush roller in its lowered position; FIG. and in

7602618 02.09.76

FIG. 6 shows an enlarged section along the line VI-VI along FIG. 4.

According to Fig. 1, a carpet sweeping machine has a frame 1 with side walls 2 and end walls 3 and a cover 4, the contains a narrow bridge 5, which is between the side walls 2 extends approximately at their central parts. It can be attached using screws 6 (see FIG. 2). On A suitable bracket 7 is attached to the sweeper, to which a handle (not shown) can be attached. At the A plurality of running wheels 8 are attached to the frame, which have a centrally mounted, transversely extending elongated brush roller 9 drive.

The brush roller 9 has a central core 10 with tufts of bristles 11 protruding therefrom, end axle parts 12 and end wheels 13, which is rotated by the frictional engagement of the running wheels 8 during the movement of the sweeper over the ground be moved.

The brush roller 9 should be adjustable in the vertical direction relative to the wheels 8 in order to avoid them in this way To be able to adapt floor surfaces. In addition, the adjustment device should avoid any rotatable element and thus also the associated translations and transmission organs. Finally, the smallest possible number of parts should be used to achieve the desired result will.

For this purpose, the brush roller 9 is movably mounted in a cross member 14, which is an elongated cam plate 15 and downwardly facing end legs 16 contains. The end legs 16 are provided with recesses 17 into which the Brush shaft parts 12 can be snapped. Besides that

7602618 02.09.76

these end legs are slotted at 18, so that a sufficient Holding force on the axle parts is guaranteed.

The bridge 5 has a generally U-shaped profile downwards protruding side walls. Inside the bridge profile is the cam plate 15 and is up through the generally U-shaped central portions of a pair of retaining springs 20 are biased while legs are around the bridge walls 19 are laid and extend into holes 21 therein.

The cam plate 15 has at least one, in the reproduced. Exemplary embodiment, two ramps 22 running obliquely downward with surfaces 23. Both ramps extend in the same transverse direction. A plate-like control member 24 in The form of a slide valve is accommodated in the bridge channel and is located between the cam plate 15 and the bridge 5. The link 24 is shorter than the bridge and can be displaced in the bridge by manual actuation of a handle 25. The handle

25 extends upward through an elongated slot

26 in the top of the bridge. The bottom of the slider 24 has at least two downwardly protruding protrusions

27, which can slide on the ramps 22.

When the handle 25 is manually operated, the slide 24 moves in a straight line and horizontally across the direction of movement the sweeper within the bridge 5 · As a result, the projections 27 run along the ramps 22 to either the To push cross member 14 straight down against the springs 20 or to allow the cross member to be under the Effect of the springs to move upwards. Through the. Vertical movement of the cross member 14 is of course the brush roller 9 adjusted to the desired height.

The limits of the movement of the handle 25 and thus the limits of the vertical movement of the brush roller 9 are determined by the ends of the slots 26.

The whole brush roller height adjustment device can easily and. can be quickly removed for cleaning and repair by removing the roller brush 9 and the springs 20.

The brush roller height adjustment device is constructed in such a way ( that it is much simpler and less expensive than the known devices, not least because the complex translations of the adjustment devices according to the prior art are eliminated.
