Description

The invention relates to a surface treatment device with a base assembly which is movable in a functional position on a surface to be machined, and with a hinged to the base assembly guide member for manual control of the base assembly.

Such a surface treatment device is well known in the field of floor cleaning and soil care equipment. The known surface treatment apparatus is a scouring-suction machine, which is provided for the wet cleaning of floor surfaces. The scouring-suction machine has a guide part with at least one handle. The guide member is hinged to a base assembly which is movable in a functional position of the scouring-suction machine on a floor surface to be machined. The base assembly has at least one tool rotatable by means of a drive and a suction strip arrangement associated with the tool. For manual control of the base assembly, the guide member can be grasped and moved by hand by an operator.

The object of the invention is to provide a surface treatment device of the type mentioned, which allows improved handling over the prior art.

This object is achieved in that a sheet guide is provided on the base assembly, on which a carriage body connected to the guide member is linearly movable, which is supported by means of at least two along the sheet guide spaced apart support points at least in the radial direction of the sheet guide. By providing the sheet guide and the linearly movable on the bow guide carriage body improved mobility of the guide member relative to the base assembly is achieved. In particular, the guide member can be pivoted over a wide angular range relative to the base assembly and so easily swung out of a work area, for example. In this way, a particularly simple and precise handling is achieved. Otherwise hard-to-reach areas can therefore be approached easier and better cleaned. In addition, an improved introduction of force and / or torque from the guide part into the base arrangement is made possible by the support of the carriage body by means of at least two support points spaced apart along the arc guide at least in the radial direction. As a result of such radial support, in particular, a moment acting transversely to the radial direction, which can be effected by an operator by means of manual forces on the guide part, as it were a force couple introduced into the base assembly. In this way, a force acting between the base assembly and the surface to be machined can be easily and be influenced precisely, if such influence by the operator is desired. For example, as a result, individual regions of the base assembly can be selectively loaded and / or unloaded relative to the surface to be processed, which on the one hand can improve the achievable machining result and, on the other hand, the manual controllability of the base assembly. On the other hand, it has also been found that the solution according to the invention advantageously reduces undesirable force and / or momentary action, which otherwise can be caused, for example, by pulling or pushing on the guide part on the base arrangements, for example in the form of a pitching moment. In that regard, an undesirable influence of forces acting on the guide part forces can be reduced to the base assembly by the solution according to the invention. The base assembly may advantageously comprise at least one drive, a rotatable by means of the drive tool and / or a Saugleistenanordnung. The guide member may advantageously be formed in the form of a stem, a handle bar, a shaft or the like. The sheet guide can advantageously form a portion of the base assembly, so that, for example, further components of the base assembly, in particular a tool or a drive, can be arranged directly on the sheet guide. The sheet guide is advantageously provided with respect to the vertical direction with respect to a base surface of the base assembly, which is arranged in the functional position at least in sections relative to the surface to be machined, projecting upwards. The sheet guide may in particular have a rectangular, a round or an oval cross-section and be made for example of a flat or a round material. The carriage body may in particular be supported on the sheet guide by means of the support points in a sliding and / or rolling manner. The term "bases" in the context of the invention comprises a point, line and / or sheet-like support. For the purposes of the invention, "along the sheet guide" in the direction of the main extension means sheet guide and insofar in the direction of an arc-shaped curved track formed by means of the sheet guide, on which the carriage body is linearly movable. In addition, the direction "radial" refers to the arc shape or the radius of the bowing. Other directions such as longitudinal, transverse or vertical direction refer to a coordinate system of the surface processing device, which is arranged in the functional position on a flat horizontal surface.

In an embodiment of the invention, the bowing is curved steadily and rectified. In this way, a functionally correct and easy movability of the carriage body is achieved on the sheet guide. Advantageously, the sheet guide is convexly curved with respect to a viewing direction oriented in the transverse direction. Accordingly, advantageously, a vertex of the sheet guide may be disposed in an upper portion of the sheet guide.

In a further embodiment of the invention, the sheet guide extends in a circular arc over an angle of at least substantially 90 °. With such an angular extent sufficient mobility of the guide member relative to the base assembly can be achieved with low overall volume. Preferably, the sheet guide may be arcuately extending over an angle of at least substantially 120 °. With such an angular extent, a further improved mobility of the guide part relative to the base arrangement can be achieved with a simultaneously moderate construction volume. Particularly preferably, the sheet guide may be circular arc extending over an angle of at least substantially 180 °. At such an angular extent, a nearly optimal mobility of the guide member relative to the base assembly can be achieved. For example, the guide member can advantageously be easily pivoted from one side of the base assembly to an opposite side, without the base assembly has to be repositioned for this purpose. In this way, the guide part can be folded down substantially flat on both sides and to that extent parallel to the surface to be machined. As a result, the base assembly can be easily controlled under an obstacle or the like, for example.

In a further embodiment of the invention, the sheet guide extends over the base assembly. Advantageously, the sheet guide may each be connected at the front end with a front and a rear portion of the base assembly, so that the sheet guide extends substantially over a longitudinal extent of the base assembly.

In a further embodiment of the invention, the sheet guide is mounted pivotably about a pivot axis on the base assembly, which is at least largely in a management level of the sheet guide. In this sense, "management level" means an imaginary plane spanned by end points of the sheet guide and a point located between these end points on the sheet guide. In other words, the pivot axis may advantageously be oriented coaxially or parallel to an axis connecting the front end points of the sheet guide. In this way, a further improved manual handling of the surface processing device is achieved. In particular, therefore, an on-the-spot rotation of the base assembly can be effected at the same time with respect to the base assembly obliquely, ie folded down from the vertical direction, guide member. This is because the sheet guide forms together with the carriage body and the pivot axis as it were a kind of universal joint arrangement. Accordingly, the base assembly can be rotated on the spot substantially independently of the angular position of the guide member relative to the base assembly by means of a torque acting on the guide member on the surface to be machined.

In a further embodiment of the invention, the pivot axis is substantially parallel to a base surface of the base assembly extends. In particular, the pivot axis can also be arranged directly above the base assembly. The base surface of the base assembly is understood to be that surface which, in the functional position, is arranged at least in sections relative to the surface to be processed and, to that extent, is oriented essentially parallel to it. By such parallel extent of the pivot axis can be achieved in a flat, in particular almost horizontal, angular position of the guide member relative to the base assembly on-the-off-turning the base assembly. If the pivot axis is immediately above the base assembly, i. is arranged at a small distance to the surface to be machined, a low point of application of the transferable between the guide member and the base assembly forces can be achieved. By means of this embodiment of the invention, it is possible to further reduce an unwanted moment influence on the base arrangement caused by the guide part. In particular, such an undesirable pitching moment can be reduced.

In a further embodiment of the invention, the carriage body has at least one supported in the radial direction of the sheet guide support member, in particular in the form of a sliding or rolling element, which forms at least a first of the bases. The support member may be point, line and / or sheet-shaped supported on the sheet guide and thus form the first of the bases. The sliding element may be in the form of a sliding block, a sliding block or the like. The rolling element may be in the form of a ball, roller, needle, or barrel-shaped rolling element. In that regard, the sheet guide can have a complementary to the shape of the support member formed guide portion, for example in the form of a correspondingly complementary guide rail, for cooperation with a sliding or rolling element designed in this way. In this way, a low-friction running of the carriage body is achieved on the sheet guide. It is particularly advantageous if a plurality of support elements are arranged along the sheet guide.

In a further embodiment of the invention, the carriage body has at least one counter-support element which is supported in the radial direction in opposite directions on the sheet guide, in particular in the form of a counter-sliding or counter-rolling element which forms at least one second of the support points. Accordingly, the carriage body in the radial direction on both sides, or in other words: radially inwardly and radially outwardly, be supported by means of the support and the counter-support member on the sheet guide. In this way, a pair of forces can be introduced into the sheet guide, at the same time a low-friction running of the carriage body is achieved. The counter-support element can point, line and / or sheet be supported on the bow guide and so far form the second of the bases. The counter-sliding element can be designed in particular in the form of a sliding block, a sliding block or the like. The counter-rolling element can be designed in particular in the form of a ball, roller, needle or barrel rolling element. In that regard, the sheet guide may have a complementary to the shape of the mating support element counter-guide portion, for example in the form of a correspondingly complementary counter-guide track, for cooperation with a thus configured Gegengleit- or Gegenwälzelement. In this way, a particularly low-friction running of the carriage body is achieved on the sheet guide. It is particularly advantageous if a plurality of counter-support elements are arranged one behind the other along the sheet guide.

In a further embodiment of the invention, the carriage body is supported in such a lateral direction on the sheet guide that a force acting about a longitudinal axis of the guide member torque on the carriage body on the sheet guide and thus on the base assembly is transferable. "In the lateral direction" means substantially transversely to the sheet guide and, to that extent, oriented substantially perpendicular to the radial direction of the sheet guide. Advantageously, the carriage body may be supported in the lateral direction by means of at least one sliding or rolling element. Consequently, a low-friction running of the carriage body in an on-the-spot rotation of the base assembly and thus a further improved handling of the surface processing apparatus can be achieved.

In a further embodiment of the invention, the sheet guide has a round cross section and the carriage body engages around the cross section, in particular by means of at least one bearing sleeve, at least in sections. The sheet guide is preferably made of a round material and may for example have a tubular hollow or a cylindrical solid cross-section. The carriage body engages around the cross section of the sheet guide in the manner of a sleeve. For this purpose, the carriage body may comprise at least one bearing sleeve. The bearing sleeve may be elongated over the substantially entire length of the carriage body, so that along the sheet guide full-surface storage is achieved at the cross section of the sheet guide. Alternatively, several, for example, two bearing sleeves, provided and arranged at opposite ends of the carriage body. In this case, only a regional storage of the carriage body is achieved at the cross section along the sheet guide. The bearing sleeve can be designed for example as a sliding sleeve. Of course, it is also possible that the at least one bearing sleeve is designed as such a basically known linear ball bearing in the form of a ball sleeve, which can also be referred to as a wave guide, so that a roller bearing guide of the carriage body is achieved at the round cross section of the sheet guide.

In a further embodiment of the invention, the guide member is connected by means of a joint member having a hinge axis with the carriage body, wherein the hinge axis is oriented substantially parallel to a guide plane of the sheet guide. In this way, a further improved manual controllability or handling of the surface processing device is achieved. For the purposes of this invention means "management level" an imaginary plane, which is spanned by end points of the sheet guide and arranged between these front end points on the sheet guide. In particular, therefore, turning the base assembly in place simultaneously with respect to the base assembly, i. be folded out of the vertical direction, guide part causes. This is because the sheet guide together with the carriage body and the joint element as it forms a kind of universal joint arrangement. Accordingly, the base assembly can be rotated on the spot substantially independently of the angular position of the guide member relative to the base assembly by means of a torque acting on the guide member on the surface to be machined. The joint element can be designed as an articulated joint, a double-sidedly movable hinge or the like.

The surface processing devices 1, 1a and 1b according to the invention are each provided in the form of a so-called scouring-suction machine for cleaning floor surfaces. Nevertheless, the solution according to the invention can, of course, also be used in connection with surface processing devices deviating from such a scouring-suction machine.

The embodiments of surface treatment devices 1, 1a and 1b according to the invention have a substantially identical construction with regard to the structural as well as functional features. Components and sections which are identical in the surface processing apparatuses 1 to 1b are provided with identical reference numerals in this respect. To avoid repetition, such identical components and portions are not separately explained in each of the embodiments. Functionally identical components and sections, which are different in their structural design, are denoted by the same reference numerals with the addition of lowercase letters.

As based on Fig. 1 it can be seen, the surface processing device 1 on a base assembly 2 and a hinged to the base assembly 2 guide part 3. The basic arrangement 2 is based on a Fig. 1 apparent functional position on a surface to be machined 4 movable. The base assembly 2 has a surface machining tool 6 which can be driven by means of a drive 5 in the form of a floor scouring roller. For the transmission of driving forces, the drive 5 via a power transmission element 7 in the form of a belt drive with the surface treatment tool 6 connected. The drive 5 is fixed to a unspecified but known as such manner on the base assembly 2. The surface treatment tool 6 is connected to the base assembly 2 by means of an elongate connecting element 8. Next, the base assembly 2 on a surface treatment tool 6 associated Saugleistenanordnung 9. The Saugleistenanordnung 9 may be provided for the extraction of a resulting in the wet cleaning of the bottom surface 4 wastewater liquor. In addition, the base assembly 2 has a in the functional position on the surface to be machined 4 supported end wheel 10. Incidentally, it will be readily apparent to one skilled in the art that, instead of the aforementioned components and components, the basic arrangement may alternatively or additionally be equipped with further components or components adapted to the respective processing purpose. For example, instead of the roller-shaped surface treatment tool 6 set against its circumference against the surface 4 to be machined, the base assembly 2 can have a plate-shaped surface treatment tool which can be set against its surface against the surface 4 to be machined. The presence of the Saugleistenanordnung 9 is far from mandatory.

The guide part 3 is configured in the form of an elongated shaft and provided for manual control of the base assembly 2. For this purpose, the guide member 3 at its not further apparent, the base assembly 2 facing away from Stirnendbereich at least one handle for manual guidance of the surface processing device 1 by an operator. In that regard, the base assembly 2 can be moved and positioned by a corresponding force and / or momentary action of the operator on the guide member 3 on the surface to be machined 4.

As further explained Fig. 1 it can be seen, a sheet guide 11 is provided on the base assembly 2. On this sheet guide 11 connected to the guide member 3 slide body 12 is linearly movable along a schematically indicated guide direction 13 of the sheet guide 11 linearly movable. The carriage body 12 is supported on the sheet guide 11 by means of at least two support points P1, P2 spaced apart from each other along the sheet guide 11, at least in the radial direction R. As a result of such linearly movable traversability of the carriage body 12 along the sheet guide 11, the guide member 3 arc-like from the basis Fig. 1 apparent angular position relative to the base assembly 2, for example in an angular position W1 and / or an angular position W2, both dashed in the representation of Fig. 1 are indicated, and any number of intermediate positions displaced. In order to achieve such a linearly movable traversability of the carriage body 12, this is to be explained in more detail and in particular with reference to the Fig. 4a to 5b apparent way sliding and / or roller bearings supported on the sheet guide 11.

As further explained Fig. 1 it can be seen, the sheet guide 11 is curved continuously and rectilinearly and extent circular arc extends over an angle of at least substantially 180 °. Nevertheless, a sufficient angular mobility of the guide member 3 relative to the base assembly 2 can be achieved even if the sheet guide 11 extends over an angle of at least substantially 120 ° or at least substantially 90 °.

Next, the sheet guide 11 is fixed at their respective end face end portions arranged on a front portion 15 of the base assembly 2 and at a rear portion 16 of the base assembly 2. In that regard, the sheet guide 11 via the base assembly 2, in particular over the length thereof, extends. Here, a vertex 17 of the sheet guide 11 is arranged substantially in relation to a longitudinal direction L centered between the front portion 15 and the rear portion 16 of the base assembly 2.

Based Fig. 2 is as a further embodiment, the surface processing device 1a can be seen that in terms of its structural design and the functional design substantially with the surface processing apparatus 1 according to Fig. 1 matches. In order to avoid repetition, only differences of the surface processing device 1a relative to the surface processing device 1 will be discussed below.

The surface treatment device 1a differs in this respect essentially in that the sheet guide 11a is mounted pivotably about a pivot axis 18 on the base assembly 2a. The pivoting wax 18 lies at least largely in a guide plane F of the sheet guide 11a, which is spanned by three along the sheet guide 11a thought arranged points, for example, front and rear end points and the apex 17. For this purpose, the sheet guide 11a is pivotally connected via a front articulated joint 19a and a rear articulated joint 19b with the other components of the base assembly 2a. In that regard, results in a pivoting movement of the sheet guide 11a, which is oriented transversely to the linearly movable traversability of the carriage body 12 along the sheet guide 11a. In this way, the sheet guide 11a forms together with the carriage body 12 and the pivot axis 18 and the front and rear articulated joint 19a and 19b, a kind of universal joint arrangement. This type of joint arrangement enables the base assembly 2a to be rotated on-the-spot by means of a torque D applied to the guide part 3, essentially independently of the respective angular position of the latter Guide part 3. If the torque D, for example, based on the in Fig. 2 indicated direction of rotation applied to the guide member 3, results in a planar rotation of the base assembly 2a about a vertical axis H according to a basis Fig. 2 apparent direction of rotation U. Such kinematics of the surface treatment device 1a is based on the Fig. 2a and 2b clarified in more detail. In one Fig. 2a In the apparent first position, the base assembly 2a is arranged substantially centered above an imaginary point P of the surface 4 to be processed. Here, the pivot axis 18 is horizontal to the surface to be machined 4 and - with respect to the plane of the Fig. 2a and b - vertically aligned. The bow guide 11a is opposite the imaginary vertical axis H (FIG. Fig. 2 ) is pivoted to the right in relation to the plane of the drawing and thus assumes an angular position of approximately 45 ° relative to the surface 4 to be machined. The carriage body 12 is positioned in the region of the rear articulated joint 19b on the sheet guide 11a, wherein the guide member with respect to the surface to be machined 4 obliquely upward and - with respect to the plane of the Fig. 2a and b - sticking out to the right. Starting from the basis Fig. 2a apparent initiation of the introduction of acting around the longitudinal axis of the guide member 3 torque D 'counteracts a rotation of the base assembly 2a counterclockwise or against Fig. 2 In this rotation, the guide member 3 remains in a substantially unchanged position relative to the surface 4 and rotates about 90 ° about its longitudinal axis. Due to the substantially unchanged position of the guide member 3 and the above-described rotation of the base assembly 2a, the torque D 'causes a relative movement between the guide member 3 and the carriage body 12 disposed on the guide member 3 with respect to the base assembly 2a and the sheet guide 11a. In this relative movement, the carriage body 12 travels along the sheet guide 11a. The sheet guide 11a, however, is tilted relative to the base assembly by about 90 ° about the pivot axis 18. Of course, an on-the-spot rotation of the base assembly 2 by more than the basis of the Fig. 2a and b apparent 90 ° possible.

Incidentally, the pivot axis 18 extends substantially parallel to the surface 4 to be machined. It is of course also possible to arrange the pivot axis 18 inclined relative to the surface 4 to be machined.

The basis Fig. 3 apparent surface processing device 1b differs from the surface processing devices 1 and 1a after the Fig. 1 or 2 essentially to the effect that the guide member 3b is connected by means of a hinge member 20 with the carriage body 12. The hinge element 20 has a hinge axis 21. The hinge axis 21 is substantially parallel to the guide plane F of the sheet guide 11, in which the carriage body 12 is linearly movable, oriented. The hinge element 20 is in the form of a hinged joint formed so that the guide part 3b with respect to the plane of the Fig. 3 out of this or hineinverschwenkbar in this is. In this way, the sheet guide 11 forms together with the carriage body 12 and the joint member 20 as it were a kind of universal joint arrangement. Regardless of the constructive differences to the hinge assembly of the surface processing apparatus 1a after Fig. 2 this joint arrangement essentially has a corresponding kinematic functionality. As such, as a result, the base assembly 2 of the surface processing apparatus 1b is rotatable in the same way as the base assembly 2a of the surface processing apparatus 1a.

Based on Fig. 4a to 6b Further details regarding the structural design of the support and linear movable movability of the carriage body 12 on the sheet guide 11 can be seen.

A first embodiment of this support is based on Fig. 4a and 4b seen. For the purpose of better representability, the carriage body 12a is only indicated by dashed lines. The carriage body 12a has a support element 22a supported in the radial direction R on the sheet guide 11a. The support element 22a is in the form of a rolling element 23. The rolling element 23 has a barrel-shaped configuration and is supported in the radial direction R against a guideway 24 of the sheet guide 11a which lies inwardly with respect to the radial direction R. In this way, the support member 22a forms the support point P1 of the carriage body 12a. Instead of the barrel-shaped configuration of the rolling element 23 may of course also be provided a spherical, conical, needle-shaped or similar configuration. Furthermore, the carriage body 12a has a counter-support element 25a supported in the radial direction R in the opposite direction to the support element 22a on the sheet guide 11a. The counter-support element 25a is configured as a rolling element 23 corresponding to the support element 22a and is supported on a guide surface 26 of the sheet guide 11a which lies on the outside in relation to the radial direction R. In that regard, the counter-support member 25a forms a second of the bases P1, P2, namely the base P2.

In particular, in order to achieve a backlash-free and substantially direction-independent support of the carriage body 12a, this has further rolling elements 23 which are each supported along the radial direction R on the support member 22a and the counter-support member 25a remote areas of the sheet guide 11a. To this extent, these two rolling elements 23 form a further supporting element 27a or a further counter-supporting element 28a.

In addition, the carriage body 12a is supported on the sheet guide 11a in the lateral direction L, ie, transverse to a main extension of the sheet guide, in such a way that it is about a longitudinal axis of the guide part 3, 3b acting torque D ( Fig. 2 ) is transferable via the carriage body 12a to the sheet guide 11a and thus to the base assembly 2, 2a. For this purpose, the carriage body 12a has a plurality of guide elements 29a arranged one behind the other along the sheet guide 11a. The guide members 29a are supported on opposite outer surfaces of the sheet guide 11a along the lateral direction L and are each formed in the form of a barrel-shaped rolling element.

Another constructive embodiment of the linear movable mobility of the carriage body 12 on the sheet guide 11 is based on the Fig. 5a and 5b seen. The embodiment shown there differs from the basis of the Fig. 4a and 4b apparent configuration to the effect that the support elements 22b, 27b and the counter-supporting elements 25b, 28b are formed in the form of sliding elements 30. Accordingly, the guide elements 29b for the lateral support of the carriage body 12b are formed on the sheet guide 11b in the form of sliding elements.

Another constructive embodiment of the linear movable mobility of the carriage body 12 on the sheet guide 11 is based on the Fig. 6a and 6b seen. The embodiment shown there differs from the embodiments according to Fig. 4a and 4b or. Fig. 5a and 5b essentially in that a sheet guide 11c is provided which has a round cross-section. The sheet guide 11c is in this case made of a round material with a full cross-section. Of course, it is also possible to provide instead a tubular hollow cross-section in the sheet guide 11c. The sheet guide 11c is encompassed circumferentially by a carriage body 12c. As based on Fig. 6a can be clarified, a respect to the drawing level of the Fig. 6a lower portion of the carriage body 12c be considered as a support member 22c. Accordingly, an upper portion 25c of the carriage body 12c can be regarded as a counter support member 25c supported in the radial direction in the opposite direction to the support member 22c on the sheet guide 11c. As with the cross-sectional representation of Fig. 6b it can be seen, the carriage body 12c has a bearing sleeve 31. The bearing sleeve 31 completely surrounds the circular cylindrical cross section of the sheet guide 11c in the circumferential direction. Instead of such a complete Umgriffes can be provided, for example, only a partial turnaround. The latter is for example the case when the bearing sleeve 31 is slotted or divided into sub-elements, which is based on the Fig. 6b should be clarified by means of there schematically drawn part plane S. The bearing sleeve 31 extends along the sheet guide 11c continuously and substantially over the entire length of the carriage body 12c. Instead, it is also possible that two compared to the bearing sleeve 31 significantly shortened bearing sleeves are provided, wherein the bearing sleeves opposite to each other at the ends of the Carriage body 12c are arranged. The bearing sleeve 31 is presently provided as a separate and connected to the other components of the carriage body 12c machine element. Alternatively, the bearing sleeve 31 may be formed integrally with the carriage body 12c. The carriage body 12c is slidably mounted by means of the bearing sleeve 31 along the sheet guide 11c. The bearing sleeve 31 is formed in this respect as a sliding sleeve. Instead, the bearing sleeve 31 may also be designed as a basically known linear ball bearing, so that a roller bearing movability of the carriage body 12c results on the sheet guide 11c.
