Definitions
- Dust hood extension device and system comprising such a dust hood extension device and an adapter
- the present invention relates to a dust hood extension device for use in connection with a dust hood for a grinding device, as well as a system comprising such a dust hood extension device and an adapter.
- the dust hood expansion device is particularly characterized in that an opening of the device is arranged eccentrically with respect to the central axis of the drive shaft.
- handheld electrical devices are known in the prior art, for example grinding devices such as angle grinders. These usually have an insert tool that can preferably be designed as an abrasive.
- the abrasive is usually matched to the surface to be processed and can, for example, be a cup wheel, which has segments with a diamond matrix, for example.
- dust is produced which in many cases can be hazardous to health and / or toxic to people, in particular the operator of the sanding device. In particular, the dust produced during grinding should not be inhaled and get into the respiratory tract of the operator of the grinding device.
- dust hoods are known in the prior art, which can be net angeord around the abrasive and are set up to Victoriafan conditions or to absorb the dust generated during grinding.
- Conventional dust hoods are used to avoid the spread of dust during grinding work in order to protect the health of a user of the grinding device.
- Such conventional dust hoods can preferably be connected to a vacuum cleaner, such as a vacuum cleaner or a dust extractor, the vacuum cleaner generating an air flow by generating a negative pressure with which the dust can be sucked out of the area of the dust hood.
- the dust hoods known in the prior art deliver good dust removal results in particular when the corresponding grinding devices to which the dust hoods are connected are used for processing flat surfaces.
- good suction performance is achieved with regard to that which occurs during grinding work Dust is reached when the dust hood lies flat on the surface to be processed.
- an opening in the dust hood is essentially completely on the surface on which the dust is generated, so that the dust can be optimally caught with the dust hood and vacuumed with the vacuum cleaner.
- the dust hoods known in the prior art can only absorb and divert a small proportion of the dust produced when the surface to be sanded is smaller than the diameter of the dust hood, which is usually a substantially circular one Has base area.
- This disadvantage of the conventional dust hoods comes to light in particular when bevels are to be created or ground, since the bevels are usually made much narrower than the diameter of a dust hood. If a bevel is to be ground or produced by grinding, a conventional dust hood usually no longer covers a sufficiently large portion of the surface to be processed to ensure effective suction of the dust that is produced.
- such a proposed cuboid device is often very difficult due to the metallic material, so that it can only be used to a limited extent for longer grinding work, for example when chamfers are to be created for a staircase, or when using large grinding devices.
- the proposed cuboid devices also often have an unwieldy, bulky shape, so that they are difficult to operate, especially for small operators with possibly low physical strength.
- the proposed solutions do not allow a simple change between the grinding of edges, bevels and / or (flat) surfaces, since the cuboid-shaped devices usually comprise a substantially right-angled recess, which allows the production of bevels, but not that Processing of smooth and even surfaces is possible.
- the practically complete encasing of the grinding area is also a easy changing of the abrasive not possible.
- a height adjustment is only possible through the complex and cumbersome screwing on of connecting means such as wing nuts.
- the opening of the cuboid device proposed in the prior art for receiving the dust generated during grinding is arranged centrally with respect to a central or rotational axis of the drive shaft of the grinding device, which often leads to tilting of the system and sub-optimal grinding results.
- the contact surface of the grinding means on the surface of a bevel to be ground is usually significantly smaller than the surface of the abrasive itself, so that large amounts of the dust produced can escape upwards and downwards.
- the dust particles that are released remain in the dust hood in order to be sucked off or removed from the area of the dust hood with the aid of a vacuum cleaner.
- the object of the present invention to overcome the disadvantages described above conventional dust hood and provide an extension device for a dust hood that offers improved suction for the dust generated during grinding work, especially when bevels are to be produced with the grinder.
- the device to be provided should enable simple handling and easy replacement of the grinding means of the grinding device.
- the expansion device to be provided would ensure a simple change between the processing of flat surfaces and the grinding of bevels and edges, would be uncomplicatedly adjustable in height and would not tend to tilt.
- a dust hood extension device for use in conjunction with a dust hood for a grinding device, the grinding device comprising a drive shaft for driving an abrasive, the abrasive rotating symmetrically around a central axis of the drive shaft during operation.
- the dust hood extension device is characterized in that it comprises a carrying device and an opening, the carrying device being set up to enclose the dust hood and, if necessary absorb emerging dust particles, the opening being arranged eccentrically with respect to the central axis of the drive shaft.
- the invention provides a technical solution which advantageously enables the user to produce or regrind bevels with a particularly low level of dust.
- the proposed dust hood extension device can be used to switch between the different sanding cases in a simple, quick and uncomplicated manner.
- the term "sanding cases” preferably denotes the different sanding situations, such as sanding (flat) surfaces or creating bevels, i.e. working on angular workplaces.
- the advantageous shape of the carrying device enables a material-saving production of the proposed dust hood extension device.
- the carrying device is designedate as a base carrier.
- the abrasive of the grinding device comprises a segment ring which is preferably arranged around the axis of rotation.
- the segment ring preferably comprises individual grinding segments which together form an annular device as a segment ring.
- these grinding segments are preferably also referred to as rotation segments.
- the segment ring has an inner distance to the axis of rotation in an area facing the axis of rotation and an outer distance to the axis of rotation in an area facing away from the axis of rotation.
- the carrying device of the dust hood extension device has an opening, this opening of the carrying device being arranged eccentrically.
- eccentric arrangement in relation to the axis of rotation preferably means in the context of the invention that the opening is arranged, for example, above the rotation segments or above the segment ring.
- the eccentric arrangement of the opening of the dust hood extension device or the carrying device is particularly advantageous because the dust generated during grinding can be sucked out of the dust hood directly at its point of origin in the area of the Rotationssegmen te when the dust hood is connected to a vacuum device.
- the carrying device assists that essentially the full vacuum suction flow generated by the vacuum suction device passes through the opening of the dust hood extension device or the carrying device is passed. As a result, improved suction of the dust generated in the entire area of the abrasive can advantageously be achieved.
- the opening of the dust hood extension device or the base support is arranged eccentrically to a central axis of the drive shaft, the central axis of the drive shaft in the context of the invention preferably also being referred to as the axis of rotation.
- the opening of the carrying device or of the adapter is preferably also positioned eccentrically to the axis of the insert tool or of the grinding means, for example the grinding segment ring. Due to the eccentric arrangement, a significantly improved grinding behavior can be achieved compared to conventional grinding devices, since, in contrast to a central arrangement, a larger area of the grinding wheel is in engagement with the substrate to be ground. As a result, tilting of the grinding means and / or the tool insert can be prevented particularly effectively. In addition, more efficient processing of the substrate is possible, since a larger area of the grinding wheel is in contact with or in engagement with the substrate.
- the carrying device of the proposed dust hood extension device is preferably set up to fit on a dust hood, ie to be able to be placed on a dust hood.
- the carrying device is designed to close any openings that may arise during bevel grinding, so that the dust produced during grinding is effectively prevented from escaping from the area of the dust hood and the grinding device. Rather, the dust that arises during bevel grinding can be extracted essentially completely on the basis of the proposed dust hood extension device, so that it no longer represents a health hazard for the operator.
- This advantage of the invention is achieved in particular that by closing the openings through the carrying device of the dust hood expansion device, the essentially complete air flow generated as a suction flow by a vacuum cleaner is passed through the openings in the dust hood expansion device.
- the dust hood can be connected to a vacuum cleaner device so that the dust that is created during sanding with the sanding device can be sucked up particularly easily, quickly and directly.
- the prompt removal of dust from the work area of the Grinding device, the health risk for the operator of the grinding device and bystanders can be further reduced considerably.
- the dust hood expansion device comprises a clip for attachment to the dust hood without tools.
- the tool-free assembly of the dust hood extension device on the dust hood, the handling of the proposed dust hood extension device is much easier because no additional tools must be carried to use the dust hood extension device together with a sander and a dust hood.
- the proposed dust hood extension device or the base support is so elastic in the area of the clip or comprises an elastic material that a clip mechanism for tool-free attachment to the dust hood is made possible.
- the material of the clip is just so elastic that the clip can easily be moved backwards without breaking off, but is also so stiff and / or firm that it moves back in the direction of the base support of the dust hood extension device when it is attached, in order to be effective
- the clip connection obtained can be released so that the grinding device can be easily dismantled, cleaned and / or serviced.
- the tool-free attachment of the dust hood with a clip to the dust hood extension device enables the user of the grinding device to switch back and forth between bevel and surface grinding in a particularly simple, uncomplicated and uncomplicated manner.
- the carrying device can be rotatably supported on the dust hood.
- the base support is rotatably mounted on the existing dust hood.
- the carrying device comprises a plastic, which can preferably be a thermoplastic or a polyamide.
- PA6GFXX or PA6GF30 is very particularly preferred.
- the base support can be made from PA6GFXX.
- the letter combination XX preferably stands for glass fibers, which can be present in the material in different proportions.
- PA6GFXX as the material of the carrying device, a particularly robust and at the same time light base carrier can be provided for the dust hood extension device.
- the materials PA6 or PA66, for example in conjunction with glass fibers, can be used without being restricted to them.
- the invention in a second aspect, relates to a system for grinding bevels that comprises a proposed dust hood extension device.
- the system comprises at least one adapter, the adapter having at least one surface for resting on a surface to be machined, and an opening, the size of which can be adapted to a desired composition of the bevel to be ground.
- the terms, definitions and technical advantages introduced for the dust hood extension device preferably apply analogously to the proposed kit.
- the adapter is designed as a wear part.
- the adapter can be produced in a different way, in particular more cost-effectively, than the base support of the proposed dust hood extension device.
- the adapter can be produced using mass production methods so that it can be produced quickly, easily and in large quantities. This is facilitated in particular by the fact that the adapter comprises polyoxymethylene (POM) or is formed from POM.
- POM polyoxymethylene
- the adapter is made from a tough thermoplastic or comprises one.
- adapters that comprise POM or are made of POM have proven to be particularly wear-resistant and resistant, and they nevertheless have the necessary sliding properties for grinding applications.
- a particularly light adapter can be provided for the dust hood extension device, so that the additional provision of the adapter does not make handling of the grinding device difficult or only to a very small extent due to additional weight.
- the use of POM is particularly preferred for the purposes of the invention, since POM is particularly wear-resistant.
- POM has low friction values and high toughness.
- the use of the adapter as a wear part advantageously leads to the fact that the dust hood extension device or the base support can be used for a longer period or are available for a longer period of use. This is particularly advantageous because the dust hood extension device or the base support is subject to increased wear due to the constant resting and / or grinding along rough surfaces.
- the adapter in particular has two support surfaces with which the adapter or the dust hood extension device rests on the material to be ground.
- the two bearing surfaces are preferably referred to as the first bearing surface and the second bearing surface.
- the two bearing surfaces of the adapter are substantially perpendicular, i. arranged orthogonally to one another.

- the inclined bevel surface in the material of the stair step forms an angle with the vertical front side and the horizontal top side of the stair step, the angle being able to assume an angle in a range of 135 ° with a uniform bevel. In the case of asymmetrical bevels, other angles can also be used between the bevel and the two starting edges of the material to be processed.
- the provision of the support surfaces preferably allows a particularly easy and simple application and alignment of the adapter or the proposed Staubhaubenerweit réellesvor direction to the corresponding edges, for example the vertical front or the horizon tal top when grinding a bevel.
- a particularly uniform bevel can advantageously be produced, which can then be further processed accordingly.
- the grinding segment, the segment ring is placed on the bevel surface through the opening of the proposed dust hood extension device or the base support or the adapter.
- the opening of the adapter which is preferably formed between the support surfaces of the adapter, can preferably be of different sizes.

- the different adapters can, for example, allow chamfers of different widths to be ground.
- the adapter which is connected to the dust hood extension device when the grinding device is in operation, can be exchanged in a particularly simple and uncomplicated manner.
- an adapter device adapted to the width of the bevel to be produced can be used.
- the different adapters can differ in particular in the size of their opening, wherein the size of the opening can be adapted in particular to the width of the bevel to be produced.
- the adapter comprises a clip for attachment to the dust hood without tools. It is preferred in the context of the invention that the clip for tool-free attachment of the adapter to the dust hood is arranged above the second support surface, ie for example above the horizontal surface of a step when the grinder is in use to create a bevel on a step . Preferably, the clip for tool-free attachment of the proposed dust hood extension device or the base support is above the dust hood the second bearing surface of the adapter arranged.
- the above statements regarding the preferably elastic nature of the clip material preferably apply analogously to the adapter clip.
- the system is designed to be height-adjustable.
- the kit from the base support adapter for fine adjustment in relation to the insert tool, for example the segment ring, can be changed in height. This ensures a particularly effective suction of the dust produced during grinding with different abrasives and different degrees of wear of the abrasive.
- the size of the bevel to be ground is between 5 and 200 mm, preferably between 10 and 100 mm. This is advantageously achieved in that adapters with openings of different sizes are provided.
- the size of the opening of the adapter is in a range from 5 to 200 mm, preferably in a range from 10 to 100 mm.
