DE20214940U1 - Device for fixing/driving a brush body arranged on the drive shaft of a cleaning machine comprises a receiving element or an insertion element arranged on the drive shaft - Google Patents

Abstract

Device (1) for fixing and/or driving a brush body arranged on the drive shaft of a cleaning machine comprises a cylindrical receiving element (2) and an insertion element (3). For form-locking force transfer at least one protrusion (9) is provided on the insertion element and/or on the receiving element and at least one corresponding recess (10) on the receiving element and/or on the insertion element. The receiving element or the insertion element is arranged on the drive shaft so that it pivots at an angle to the axis of rotation against a restoring force. Preferred Features: The receiving or insertion element is held by a curved, especially meandering suspension (6).

Description

The invention relates to a device for fastening and / or driving one on the drive shaft a cleaning machine arranged brush body, with a substantially hollow cylindrical Receiving element and an insertable element which can be inserted therein, being for positive power transmission at least one projection on the insertion element and / or the receiving element and at least one corresponding recess on the receiving element and / or the insertion element is provided.

Devices of this type are known in practice, in which the slide-in device permanently arranged on the cleaning machine or receiving element provided rigidly with unchangeable orientation is and the opposite End of the brush body a separate fastener in the cleaning device inserted state is fixable.

The disadvantage here is that at often due to the assembly of the brush body the spatial installation position and the shape of the case the cleaning machine is tilted into its installation position and then is brought into the intended orientation, whereby the connecting elements are exposed to high loads and can be damaged.

The object of the invention is that to avoid the aforementioned disadvantages and a device for attachment and / or for driving according to the preamble to specify of claim 1 with which an assembly or a replacement of the brush body easily and without any damage causing loads can be carried out.

This task is solved by a device of the type mentioned, wherein the receiving element or the insertion element against a restoring force to the axis of rotation is angularly deflectable on the drive shaft. hereby is a lateral tilting of the brush storage possible, so that both assembly and disassembly or replacement of a brush body clearly easier possible is.

Preferably, it can be deflected at an angle Arrangement of the receiving or insertion element from an arcuate, in particular meandering trained suspension be held so that a flexible deflection with integrated Restoring force in a simple manner without complex construction and a high number of separate components possible is.

The suspension can circumferentially distributed holding arms or from a rotating one Retaining ring consist and in particular of plastic or another suitable material.

According to the insertion element be conically tapered at least in the region of its free end, so that a particularly simple insertion is possible and preferred the receiving and / or inserting element when establishing the connection automatically positioned in a correspondingly centered deflection can be.

The receiving element can also be used for this an expanding at least in the area of its free end Have recording cross-section.

The insertion element can advantageously a circumferential outer jacket formed from rectangular surfaces and have a polygonal cross section and the receiving element an adapted to this, with the inserted insert element with the outer sheath in flat Have contact inner jacket so that when inserting inevitably centering in the direction of rotation around the longitudinal axis and the number of protrusions engages in the corresponding number of recesses.

In a preferred embodiment of the Invention can the receiving or insertion element in one in about the end cavity of the brush shaft the cleaning machine can be provided so that one in the brush shaft integrated brush storage is provided.

The following is one in the drawing illustrated embodiment of the invention explained. Show it:

1 sections of the insertion element of an embodiment of a device according to the invention,

2 sections of the receiving element of an embodiment of a device according to the invention and

3 the objects according to the 1 and 2 in an interconnected state.

In all the figures are the same or similar components matching Reference numerals used.

1 shows a device 1 for fastening and / or driving a brush body arranged on the drive shaft of a cleaning machine. The device has an essentially hollow cylindrical receiving element 2 and an insertable insertable element 3 on. The receiving element 2 is in the illustrated embodiment in an end cavity 4 the brush shaft 5 integrated into the cleaning machine.

For angular deflectability is the receiving element in the illustrated embodiment 2 from a meandering suspension 6 held.

The insert element 3 is tapered in the region of its free end and has a circumferential outer jacket formed from rectangular surfaces and having a polygonal cross section 7 on, which is in surface contact with the insertion element with the adapted and in the assembled state inner jacket 8th of the receiving element 2 corresponds.

For the power transmission required for driving the insertion element arranged on the drive shaft 3 to on the brush shaft 5 arranged receiving element 2 have insertion element 3 and receiving element 2 protrusions each 9 or corresponding recesses 10 on.

Of course, the arrangement of the receiving element 2 and insertion element 3 can also be provided vice versa, it being advantageous if the movable suspension 6 is provided in the part exchanged when the brush is changed, that is to say insofar as a brush-side fastening means.
