Abstract

In order to facilitate moving with a cleaner comprised, on one side, of two parallel brush-rollers (2, 3) secured to a frame (1) and actuated so as to rotate in opposite directions and, on the other side, of a push bar (8) attached to the frame (1), it is suggested by the invention that the push bar (8) be fixed at a distance from the frame (1) in the direction of the rotating axis of the brush-rollers (2, 3) and rotationally fixed to the frame (1) to enable a rotation following a cycle parallel to the axis of rotation.

Description

The invention relates to a cleaning device with two mounted parallel to each other on a frame, in opposite directions rotating brush rollers and with a push handle engaging on the frame, which in Direction of the axes of rotation of the brush rollers from that Frame protrudes and rotates one parallel to the axes of rotation of the brush rollers Direction is rotatably connected to the frame.

Such a cleaning device is from US-A-4,570,278 known.

With this type of cleaning, where the brush rollers rotating in opposite directions, the propulsive forces rise the two brush rollers onto the cleaning device, to move the cleaning device must therefore Thrust or tensile forces are exerted as the brush rollers do not contribute to this movement.

It is an object of the invention to provide a generic cleaning device to train so that the rotational movement of the Brush rollers for moving the cleaning device can be exploited.

This task is the beginning of a cleaning device described type solved according to the invention, that the push handle at its end remote from the frame arranged transversely to its longitudinal direction at a distance Has grip elements and that the grip elements in essentially symmetrical to one parallel to the axes of rotation of the brush rollers running between them lying vertical plane are arranged.

Such an arrangement makes it possible to use the cleaning device to tilt an axis between the two Brush lies and runs parallel to them. Thereby can be particularly easy with the push handle Torques are transmitted to the frame, which is optional one or the other of the two brush rollers burden more and then cause the whole Device alternates to the left or to the right.

In a preferred embodiment can be provided be that the push handle is at right angles to the direction of the Rotating axis pivotable with the frame connected is. This allows the push handle in its Height can be pivoted, if necessary also in different Angular positions are determined. A non-rotatable Connection is only necessary in one direction which runs parallel to the axes of rotation of the brush rollers.

According to a preferred embodiment, that the push handle between the brush rollers on the frame attacks, especially the point of attack of the push handle on the edge of the frame in the area of the ends the brush rollers.

In a particularly simple embodiment, the Push handle have the shape of a rod.

However, it is also possible to use the push handle in a manner known per se Form in the form of a U-shaped bracket.

In a further preferred embodiment, that the push handle is perpendicular to the Frame pivot axis pivotable in one position is in which it is perpendicular to the direction of the axes of rotation the brush rollers protrude from the frame. This is the one usual position of the push handle for a two-brush cleaning device, in this position the cleaning device in the conventional way by pushing and tractive forces are moved. This possibility of turning of the push handle thus enables the user optionally move the device in a conventional manner or by tilting the frame through the Let the movement of the brush rollers shift.

It is convenient if the push handle in his two positions in which he is towards the Axis of rotation of the brush rollers extends or transverse to it, is fixable.

Especially with such a configuration in which the Push handle also in a conventional, transverse to the axis of rotation the position of the brush rollers pivotable it is advantageous if the point of attack of the Push handle on the edge of the frame in the area of the ends of the brush rollers. This makes it for the user possible the frame with its the point of attack insert the opposite end under objects, for example under cupboards etc. without doing so the push handle attacking the frame is annoying.

In a preferred embodiment, that the push handle is divided into at least two sections which is connected to one another in a working position against it are fixed in a rest position are foldable.

It is particularly advantageous if the folded Sections of the push handle on top of the Frame can be placed.

Such a construction allows the push handle to save space and, if necessary, open it the top of the device so that overall a very compact structure is achieved when the device is not in use.

The cleaning device shown in the drawing includes a hood-shaped housing 1 which is open at the bottom, in which emerging from the housing 1 at a distance two brush rollers 2, 3 of the same type to one another rotatable about axes of rotation running parallel to one another are stored. The brush rollers are powered by a drive 4 and suitable transmission means, shown in Embodiment drive belt 5, 6, in opposite directions driven in rotation.

The type of storage of the brush rollers 2, 3 is in the Drawing not shown in detail, it is here about conventional technology. You can do this at a warehouse be arranged in a special frame or on the housing As part of this application, all of these parts that the Store brush rollers 2, 3, commonly referred to as "frames".

At the top of the case intervenes in the middle the two brush rollers 2 and 3 and in the immediate vicinity Near a side edge 7 of the housing 1 Push handle 8 on, with the housing 1 in from Drawing about an axis not clearly visible is rotatably connected, which is parallel to the axes of rotation the brush rollers 2, 3 runs. The push handle is against it 8 both a horizontal and a vertical pivot axis, both perpendicular to the The axes of rotation of the brush rollers 2, 3 are pivotable.

The pivoting about the horizontal pivot axis leads to the fact that the push handle 8 compared to that by the two Brush rollers 2, 3 spanned in a different plane Tilt angle can be pivoted by suitable, not shown in the drawing The push handle can optionally be in various ways Angular positions can be fixed.

A pivoting of the push handle 8 around the vertical Pivot axis means that the push handle 8 from a Position in which it is in the direction of the axes of rotation of the Brush rollers 2, 3 extends (in Figure 2 with extended Lines) can be pivoted into one position, in which it is transverse to the axis of rotation of the brush rollers 2, 3 extends (in Figure 2 in dash-dotted lines shown). Suitable means can also be provided here be the push handle described in both Determine positions.

In the position in which the push handle is transverse to The axis of rotation of the brush rollers 2, 3 extends (dash-dotted lines in Figure 2), the housing 1 by application be pushed by pushing and pulling forces press both brush rollers 2 and 3 with the same size Forces on a surface to be cleaned 9.

If the push handle 8 is pivoted into a position in which is in the direction of the axes of rotation of the brush rollers 2, 3 extends (solid lines in Figure 2), can a torque on the housing via the push handle 8 1 are exercised so that the housing 1 tilts can be. The axis of this tilt is parallel to the axes of rotation of the brush rollers 2 and 3 and lies between these.

To undertake such a tilting of the housing 1 can, the push handle 8 has at its free end a cross member 10 on a rod-shaped Section 11 in the manner described with the housing 1 is connected and at both ends at a distance grip elements 12, 13 arranged relative to one another wearing. By pressing one of the two handle elements 12 or 13 downwards, the housing 1 is tilted in such a way that one brush roller firmly against the one to be cleaned Surface 9 is pressed while the other of her is lifted off.

This is in Figures 3 and 4 for different Tilt directions shown. Because the brush rollers reciprocally are driven in rotation, this leads to the fact that the more firmly pressed brush roller its rotary movement transfers more to the surface 9 than that of the surface 9 lifted brush roller, and this leads to a displacement of the housing 1 relative to the surface 9. This shift results solely from the tilt, the user therefore only needs the power for that Spend tilt to shift the housing 1 to achieve the actual shift movement generated by the drive 4.

By pressing the handle elements 12 alternately and 13 can thus the housing 1 alternately in the tilt one way or the other, and this leads for an alternating displacement of the housing 1 in one way or the other.

By pivoting the push handle around the vertical The user can choose the swivel axis at any time whether he in a conventional manner, the housing 1 by sliding and want to move or move the move the housing only by tilting the housing trigger and then perform by driving the device want to leave.

FIGS. 5 and 6 show a modified embodiment shown a cleaning device that is constructed essentially the same as that of the figures 1 to 4. The same parts therefore have the same reference numerals.

In contrast to the exemplary embodiment in FIGS. 1 to 4 is in the cleaning device of Figures 5 and 6 the push handle 8 divided into one in its middle lower section 14 and an upper section 15 which about a transverse to the longitudinal axis of the push handle 8 Axis are pivotally connected. The two sections 14 and 15 can by a suitable Device not shown in the drawing is specified to be locked against each other, that a pivoting of the sections 14 and 15 against each other not possible.

The push handle 8 is on its storage on the housing 1 pivotable about a further axis that is parallel to the pivot axis of sections 14 and 15 and can also be determined if necessary.

This configuration makes it possible to use the push handle 8 space-saving on the top of the housing 1 to accommodate when the device is not in operation. For this purpose, the lower section 14 is parallel to the top of the housing 1 is pivoted, the upper section 15 turned 180 ° with respect to the lower section 14 and also placed on the top of the housing 1, as can be seen from Figure 5. This gives a very compact folding of the push handle on the top of the housing 1.
