Description

The present invention relates to a mounting device for a hand machine, which can be used in the cleaning of an object used. Attachments may be arranged on the hand-held machine, preferably rigidly mounted to assist or carry out operations by the hand-held machine.

The present invention is preferably used in the field of civil engineering and it can be supported with the attachment according to the invention, the cleaning of formwork elements. In particular, it is used in the cleaning of frames of concrete formwork systems, preferably for walls and ceilings. With such frame elements, a factory-welded frame made of steel or aluminum is used.

After completion of a concreting with formwork elements, it is necessary that they are cleaned after removal within a short time of the adhering to these concrete residues. In a variety of formwork elements, a stationary cleaning is advantageous, the individual elements are brought to a central cleaning plant and then have to be transported back to the site for further use. There is thus the requirement to carry out the cleaning of formwork elements, in particular of frame formwork, on the site and to save in this way transport routes that would be incurred in a stationary cleaning.

Due to the tenacity with which concrete residues adhere to formwork elements, the use of a cup brush on a tubular manually operated holding element, as this example in the DE 20 2006 011 045 U1 is not possible. To the cleaning effect of industrial devices, such as this example in the DE 1759493 is described to achieve higher forces on the formwork elements necessary. These forces can be provided in manual operation of the cleaning devices, for example by scrapers or cup brushes on angle grinders on the formwork elements. However, it should be noted that the formwork elements, in particular the frame elements, are primed and have a paint that must remain when removing the concrete residues on the frame elements. Therefore, especially when using cup brushes and angle grinders, make sure that the brushes are adapted to the elements to be cleaned. Despite such an adjustment of the brushes, the angle grinders are guided by hand and it can not be ensured during prolonged use that the same contact pressure is maintained. Furthermore, fatigue phenomena occur in the user's arm and shoulder area, which also argue against the long-term use of this cleaning method.

In the DE 3942784 A1 is a device for the treatment of frames, provided in the corners and fitting elements of concrete formwork, in which a slider in a special angle grinder is provided, the sliding member is displaceable in an upper part perpendicular to the cleaning surface and the upper part is mounted on a guide frame with skids. The sliding part is adjusted via a threaded rod with respect to the upper part. Cutting discs, cup brushes or nylon brushes can be attached to the special angle grinder and the distance of this surface to be cleaned can be precisely adjusted. The use of this device is limited to the application of the top of the surfaces to be cleaned. A disadvantage is the high weight due to the large number of angle grinder holding frame parts.

It is the object of the present invention to provide a mounting device for a hand machine, in particular an electric hand machine, preferably an angle grinder, by means of which a flexible cleaning of formwork elements, in particular of frames of formwork elements, is made possible. It is advantageous to ensure substantially equal pressure points during the cleaning process for a large area and to counteract fatigue of the user despite an application in manual mode.

This object is achieved by a mounting device for a hand machine according to claim 1. Inventive developments are given in the dependent claims.

According to the invention, an attachment machine for a hand machine is presented which comprises: a base element which can be attached to the hand machine between the hand machine and a cleaning element that can be moved relative to the base element and driven by the hand machine, and at least one roller rotatably mounted on the base element an object to be cleaned is movable guided on at least one side, while the object to be cleaned can be cleaned at least in sections by the cleaning element movable relative to the base element. In this way, a guide of the hand machine and thus of the cleaning element can be ensured along the object to be cleaned, whereby an improved cleaning effect can be achieved and lower fatigue occurring in the user.

By the hand machine, a linear movement of the cleaning element with respect to the base element can be generated and due to this relative movement of the object to be cleaned can be subjected to the cleaning process. The advantage of the linear movement is the targeted moving out in two directions of the removed particles from the object to be cleaned.

According to the invention it is preferred if the hand machine has a rotary drive over which the cleaning element is rotatable. In this way, for example, conventional angle grinders can be used and a very intensive cleaning process can be achieved due to the constant high speed streaking due to the rotation. However, the invention is not limited thereto and it may also be a combination of rotational movement and linear movement generated by the hand machine on the cleaning element.

It is preferred if the axis of rotation of the at least one roller runs essentially parallel to the axis of rotation of the cleaning element. In this way, tilting during the movement process on the object to be cleaned be prevented and a uniform cleaning process can be ensured.

According to a preferred embodiment, the base element has a support plate for the hand machine and at least one side attachment for receiving the roller. The platen takes up the hand machine and the side mount establishes a rigid connection of the platen to the axis of rotation of the roll. In this way, the leadership function can be implemented in a hitch device according to the invention with little device complexity.

The side mount and / or the platen may be made of mild steel. In this way, a robust attachment can be implemented, which can withstand different weather conditions.

The support plate and the at least one side attachment may be joined together by welding, whereby a simple and inexpensive connection method for producing the attachment device can be implemented.

If the roll has a plastic coating, the hitch can be moved along the object to be cleaned with little abrasion during the cleaning process.

The roller is preferably attached via a threaded rod to a side mount, so that at low axial length of the roller an effective guiding operation can take place and the side attachment with the roller can be easily connected.

In the embodiment according to the invention, two rollers fixed to the base element, between which the object to be cleaned can be guided, are provided at a predetermined distance. In this way, a limitation of the movement between the hitch and primitive to the direction of movement in both directions can be limited, whereby a safe cleaning process can be implemented.

According to a preferred embodiment, the object to be cleaned can be guided by the rollers during cleaning on its opposite side surfaces. In this way, in particular frame elements of formwork can be cleaned with high accuracy.

In the invention, the axis of rotation of the cleaning element may be outside a plane defined by the axes of rotation of the two rollers. In this way, a mutual influence of cleaning process and leadership process can be prevented and a safe material discharge of the material to be cleaned removed material can be implemented.

It is preferred if the distance between the two rollers is changeable, since in this way adaptation to different objects to be cleaned is possible.

At least one of the two rollers may be mounted in a slot in at least one of the side fasteners of the base member, so that only the attachment of the rollers must be relaxed and a displacement of the axle must be made to make the adaptation to other frame members.

At least one of the side fasteners of the base member may have at least two holes for receiving a roll in two different positions. This is advantageous if two different transverse dimensions of the frame members that are to be cleaned, are present and thus an accurate adjustment of the distance in the transverse direction of the roles makes sense.

According to the invention, the geometric design of the base element can be adapted to the cleaning of frames of concrete formwork. In this case, further features of the formwork elements can be taken into account, such. B. further inclined surfaces, may be provided for the guide elements, such as. B other rollers with inclined axes.

In at least one side attachment, a recess for receiving a fastening means may be provided, via which the hand-held machine can be rigidly fastened to the base element. In this way, the hand machine does not have to be specially adapted to the cleaning process, but existing .Ausnehmungen can be used on the hand machine for attachment of the hitch.

In a preferred embodiment, a recess on the base member is arranged in such a manner that in this a fastening means for fixing the base member with respect to a receiving element of a handle for the hemp machine can be introduced. Since multiple recesses are provided for handles typically on angle grinders, a secure attachment of the hitch can be implemented using these recesses.

Between the hand machine on the one hand and the roller and the cleaning element on the other hand, a cover can be provided by the ejection of previously adhering to the object to be cleaned material in the axial direction of the rotary drive of the hand machine can be prevented. This increases the safety of the user.

The cover may be U-shaped, so that ejection of previously adhering to the object to be cleaned material perpendicular to the axial direction of the rotary drive and perpendicular to the direction of movement of the object to be cleaned can be prevented. In this way, the movement is not hindered on the object to be cleaned.

The cover is preferably made of Plexiglas or other translucent material. This allows the cleaning process to be closely monitored.

In the case where the cover is formed of sheet metal, preferably center sheet, or other metallic material, a cover with high durability can be implemented with low production costs.

The sheet is preferably made of aluminum, so that a cost-effective production is possible.

The cleaning element is a brush, preferably a cup brush, so that the cleaning process can be carried out with low production costs and high efficiency. When using a cupped pot brush, a longer service life than with other Topbürstenarten be implemented.

The diameter of the cup brush is preferably greater than 10cm and less than 20cm to account for formwork elements, in particular frame elements used in construction.

The hand machine is preferably an electric hand machine, since in this way with high efficiency and low weight cleaning process can be performed. The hand machine is more preferably an angle grinder, because due to the angular gear, the thickness of attachment to the hand machine can be made small and thus a compact cleaning device can be implemented.

It is preferred that a cleaning element is attached to this working device, in which a relative movement, for example with respect to the housing of the implement, can be generated, this relative movement is used for cleaning. The hand machine is preferably an electric hand machine, but can be driven in any other way, such. B. also by a gasoline engine. It is particularly advantageous if the electric hand machine has an angle gear, so that the drive axis preferably extends at right angles to the housing axis and thus in a compact device, a rotary drive of a tool is possible.

However, the present invention is not limited to a rotary drive, for example, linear drive movements and other drive movements can be generated. For an electric hand machine with bevel gear below the term "angle grinder" is used, this is synonymous with "cut-off" used here.

The FIGS. 1A to 1C show a basic element 1, which is attachable to the head of an angle grinder. The base element 1 has a support plate 2, on whose opposite sides to the same side of the support plate above side fasteners 4 and 6 are arranged. The basic element 1 is for attachment to a hand machine adapted, wherein the support plate 2 has a recess 8 into which a cylinder-like projection of the hand machine can be introduced. However, the present invention is not limited to a circular recess 8, but there may be any adjustment of the support plate to the hand machine, if a running of a drive axle is made possible by the support plate.

The support plate 2 need not be disc-shaped, but it may also be an adaptation to an outer contour of the hand machine. The outer contour of the support plate 2 is also preferably adapted to the housing design of the hand machine, wherein an arcuate outer edge 10 of the support plate 2 can extend substantially parallel to the housing of the hand machine and a straight outer edge 12 is provided to abut with a housing edge of the hand machine be. The shapes of the edges 10 and 12 may be adapted to the particular design of the hand machine.

The invention is not limited to the fact that the support plate 2 and the side fasteners 4 and 6 are attached to each other as separate components, but these may also be provided integrally in the production.

A side mount 6 is in plan view in FIG FIG. 2 shown. The side attachment 6 has a cylinder portion 18 and a flat portion 20, which terminates via an intermediate portion 22 to the cylinder portion 18. In the flat portion 20, which is preferably formed as a flat cuboid, a mounting recess 24 is introduced, via which the hand machine is attached to the side mount. It is preferred that in the recess 24, a screw can be introduced and this can be introduced into a receptacle for a handle of the hand machine.

In the cylinder portion 18, a rod recess 26 extends substantially perpendicularly to the central axis of the fastening recesses 24, via which a threaded rod 28, which in FIG FIG. 3 is shown in the side mount 6 can be fastened. The Threaded rod 28 can, as it is in Figure 1A is shown mounted over a lock nut 30 in the side mount, wherein the threaded rod 28 preferably around its projecting portion 28 a, the in Figure 1A is shown protruding from the side mount 6.

In the end face 32 of the threaded rod 28, a bore 34 is introduced, in which a roller 36 with the threaded rod 28 is connectable. The roller 36 is preferably rotatably attached to the threaded rod. The protruding section 28a is advantageous for the reason that a cleaning element can be provided in this area above the support plate 2.

According to the invention, it is possible that the rollers 36 are attached directly to the side mount. However, it is preferable that the rollers are arranged at a predetermined distance above the side mount, since they do not have a guide function below the predetermined distance, which will be described later.

The side attachment 4 is mirror-inverted to the side attachment 6 and to this a threaded rod 28 and a roller 36 are also attached. The side mounts 4 and 6 are provided in such a manner with respect to the platen 2 that the flat portions 20 of the side mounts 4 and 6 are connectable to the extension portions 14 and 16 of the platen 2.

The distance A of the side fasteners 4 and 6, which is also due to the attachment to the support plate 2 is due to the transverse dimension of the hand machine. It is not necessary that the distance between the side mounts 4 and 6A be parallel over the entire extent of the flat portions 20. Depending on the outer contour of the hand machine, the design of the side fasteners 4 and 6 may be adjusted accordingly.

The rollers 36 on the side mountings 4 and 6 are preferably secured to the threaded rods 28 via bolts 38, more preferably cylinder head bolts. In an advantageous embodiment according to the invention is in the threaded rods 28th a bore with Allen screw for introducing the screw 38 for the roller 36 is provided.

In this way, it is possible that an object to be cleaned between the rollers 36 is supported by its opposite side surfaces by the rollers 36 and can roll on them.

The material used for the side fasteners and the support plate is preferably mild steel, in particular S235JRG2 or the like, are used. The focus is here on a robust design for receiving the costs incurred during manual operation on the threaded rods 28 forces. As rollers 36 are preferably those with plastic coatings used. However, it can be used any role, wherein preferably elastic material is provided in the outer periphery.

In the outer shape of the support plate 2 and the side mountings 4 and 6 is preferably oriented to the outer design of the hand machine, wherein the height of the side fasteners 4, 6 in the axial direction of the threaded rods 28 can be determined by the thickness of the hand machines and the outer shape of the design arcuate outer edge 10 can be co-determined by the front portion of the hand machine adjacent to the rotary drive.

After the description of the basic element 1 with inserted threaded rods 28 and rollers 36 in the FIGS. 1A to 3 will be referred to the design of the hitch with a cover 40 below.

For the sake of intuition, in the FIGS. 4A to 4C the attached to the hand-held cleaning element, preferably in the form of a cup brush 42 shown. In FIG. 4A is located in the front view of the hitch the cleaning element 42 on a shaft 44 with the central axis B of the hand machine 46th In this front view of FIG. 4A is the cleaning element 42 between the rollers 36 above the recess 8 in the support plate. 2

The view from the left in FIG. 4B It can be seen that the shaft 44 parallel to the threaded rods 28, but offset in an axial direction X of the hand machine to this.

By arranging the rollers 36 with respect to the cup brush 42, preferably in the form of a cup brushed pot, it can be seen that with the embodiment of the invention by the arrangement of mounting device with base 1 and the rollers 36 and the cleaning element 42 between them a space H is created in which a in FIG. 4C shown elongate object 48 to be cleaned, preferably a formwork element, more preferably a frame element of a formwork, can be guided by the rollers 36, while a pointing to the cup brush 42 surface of the article 48 can be cleaned by the cup brush 42.

This cleaning process is directly above the cup brush 42 in the space H in the FIGS. 4A and 4B made, due to the rotation of the cup brush 42 from the object to be cleaned 48 separated parts are ejected. Since, due to the high rotational speed of manual machines, the temperature of the detached particles can be increased from the object, it is preferred if a cover 40, which in the view from the front in FIG. 4A has the shape of a U-shaped profile, provided in such a way that in the direction perpendicular to the longitudinal direction X of the hand machine transverse direction Y, in which the rollers 36 are arranged side by side, wall portions 40a and 40b are provided, which is an emergence of the detached particles from Prevent the object 48 in the direction Y. Between the wall sections 40a and 40b there is a base section 40c of the cover 40, in which both a recess for the rotary shaft of the cleaning element and / or the cleaning elements, preferably in the form of the cup brush 42, as well as recesses for the threaded rods 28 are introduced.

The cover 40 may be made of any material. In the case of the Plexiglas embodiment, there is the advantage that the cleaning effect can be examined more quickly. According to the invention, however, a sheet, preferably in the form of a center sheet with, for example, 3 mm thickness is preferred. In addition to the low production costs, this variant also has the advantage of a long service life.

In FIG. 4C For example, the object 48 to be cleaned is shown between the rollers 36, with the opposite side edges 48a and 48b not in abutment with both rollers 36 simultaneously. However, the distance of the rollers 36 may alternatively be chosen so that the object to be cleaned 48 is guided by both rollers simultaneously. The advantage here is a tighter fit. On the other hand, however, the contact pressure of the cleaning element on the surface to be cleaned can be made uniform only with great effort.

However, the present invention is not limited to the configuration of the basic element. The basic element has the function, on the one hand to hold the hand machine and thus to allow attachment of the cleaning element to the hand machine, and on the other hand provide a support for guide elements on the object to be cleaned. These guide elements are in the illustrated embodiment rollers 36. However, these can be inventively arbitrarily designed as long as a guide of the base element is to be cleaned on the object.

Furthermore, the invention is not limited to only one embodiment of the side fasteners 4 and 6. In an alternative, the recesses for introducing the threaded rods 28 may be formed in the side fastening elements 4 and 6 as slots, so that a different relative distance between the threaded rods for the rollers 36 is possible. In this way, with a basic element, the cleaning of a variety of different formwork elements, in particular frames, are made.

As an alternative to the elongated holes, a plurality of holes spaced transversely in the direction Y for receiving the threaded rods 28 may be provided in each side fastening element so that they can be arranged in different locations depending on the object to be cleaned.

Furthermore, the invention is not limited to that, as in FIG. 4C shown in both the axial direction X and in the transverse direction Y, a distance between the central axis of the shaft 44 and the axes Z of the threaded rods 28 is present. For example, the cleaning element 42 may be provided with its center axis B stronger between the rollers 36.

The diameter of the brush is preferably in the range between 10 and 20 cm, more preferably in the range between 120 and 125 mm including the range limits. In such an embodiment, a plurality of commercially available frame elements can be cleaned by the cleaning element.

Due to the inventive design, the attachment can be applied after attachment to the hand machine and the application of the cleaning element on a formwork element to be cleaned, preferably the frame, and this can be moved with little effort by the rollers 36 along the frame. This ensures that the cleaning element is in every moment in contact with the object to be cleaned and due to the attached rollers 36 slipping of the cleaning element is prevented from the surface to be cleaned.

By manual operation of the cleaning process can be controlled and can also, preferably in combination with a cover 40 made of Plexiglas, the primer or a paint on the frame elements are selectively removed.

The design of the hitch is also not limited to recesses in the side mounts for attachment to the hand machine. The base member, preferably the side fasteners, may be configured in such a manner that a plurality of recesses may be provided to accommodate different ones Types of handheld machines or the side mountings may be slidably provided on the platen to accommodate different width dimensions of various hand machines.
