Definitions

  • the invention relates to a protective and guiding device according to the preamble of claim 1 and to a device according to the preamble of claim 8.
  • Such a device and such a device are out DE 100 12 208 A1 known.
  • the device described herein has the function of machining objects mechanically. In particular, it is provided to saw selected objects, or otherwise separate.
  • machining with the device or its tool is understood as cutting, milling, grinding, planing or similar mechanical machining. In the following, only separation or grinding is used, in which case all the aforementioned processing methods are understood.
  • protection and guidance device is understood to mean a device which can be adapted as an adapter to a drive unit, for example to a hand-held machine tool the size of a hand drill.
  • the tool and drive unit form a unit which are movable relative to the protective and guide device.
  • the protective and guiding device serves to receive a tool, for example a cutting disc or a saw blade, this being completely enclosed.
  • the protective and guide device serves as a system and guide device, so that by moving the drive unit, the tool for separating, grinding or the like from the protective and guide device during the machining process can be brought out.
  • backdrop means means that cause the tool to move relative to the protection and guide means.
  • the backdrop may be a slot guide in the protective and guiding device is provided. The bearing of the rotating tool is guided along this slot guide.
  • the term “gate” is understood to mean a guide device on which slides are guided, for example.
  • window frames When renovating old buildings, it is known that window frames must be removed from the masonry, so that they can be replaced by new ones. For this purpose, it is necessary to remove the usually formed from wood frame by means of a separator of the masonry.
  • metal elements that fix the frame to the masonry to remove in a separate or the same step.
  • the method is characterized in that a frame of a window to be renovated is separated out with a device according to the invention.
  • Said device has a tool in the form of a cutting disc, which is arranged rotatably and pivotally on a fixing device.
  • the cutting disc in the corners of a window frame and in the corners, formed by window frames and masonry, can penetrate.
  • the separator penetrates obliquely, for example at an angle of 45 degrees.
  • the hand-held implement presented herein has a drive unit, wherein the drive unit is coupled to a protective and guide device.
  • a cutting disc is mounted within the protection and guide device.
  • the cutting disc is in turn directly coupled to the drive unit and is rotated by this.
  • Drive unit and cutting disc are movable relative to the protection and guide device.
  • the protective and guide device itself is designed such that in the idle state, the cutting disc is arranged directly in the housing. This avoids that the cutting disc is damaged in any way during transport and further avoids that people can be injured by improper handling of the manual tool.
  • the separating disk can be moved translationally in one direction in such a way that it emerges from the protective and guiding device via an outlet opening. If the entire hand tool is removed from the processing situation, then a return mechanism ensures that the cutting wheel is automatically guided back into the protective and guiding device.
  • the user usually attacks the manual tool on the drive unit, sets the manual tool together with the protection and guide device to the window frame and triggers the drive or the rotation of the tool.
  • a translational movement - caused by a manual movement - causes the rotating cutting disc to be fed with an advance and thus brought into a single predetermined defined direction.
  • the cutting disc exits the protective and guiding device, wherein the protective and guide device itself remains stationary.
  • the workflow process is repeated in such a way that the protective and guide device is newly set together with the drive unit.
  • the processing can only be done in one direction. Processing in the range of an angle, for example within a window corner, is not possible in this way.
  • the protective and guide device is set obliquely together with the drive unit in the corner of a window frame.
  • the danger is that the per se at right angles formed protective and guide device is not completely rests and thus only selectively loaded and the user is exposed to an increased risk of injury.
  • a good quality cut result is not to be expected in this way.
  • the user is exposed to a high dust load.
  • Another disadvantage of the known device is that the user must apply directly to the drive unit with its power guide, so that a torque is created, which means that the protection and guide device can not lie correctly flat at the preferred angle.
  • a protective housing for a saw blade of a circular saw known.
  • the saw blade is mounted centrally on a saw shaft, which in turn is mounted on a sliding saw carriage.
  • the saw blade can be guided along a slot gate in one direction to an outlet opening in the protective housing.
  • a protective housing in which a saw blade is mounted.
  • the protective housing is specially designed in its contour so that it can be attached to a corner formed at an angle of 90 degrees.
  • the saw blade can be guided from an exit opening into the angle. Again, the blade is feasible along a slot gate with a translational degree of freedom.
  • the device shown herein comprises a protective and guiding device for mounting on a drive unit, which consists of a substantially hollow housing with a rotating tool in the form of a milling or cutting disc. Furthermore, the device is developed in such a way that the tool passes through one of the housing-forming support plate through one or more open slots. Furthermore, the housing has a retractable part. The retractable part forms an outlet opening for the tool, which at least partially penetrates the tool.
  • the object of the invention is to develop the protective and guiding device and a device with such a device such that at least one disadvantage of the prior art is avoided.
  • the invention is based on one of the significant advantages that acute angle, but also obtuse angles can be achieved equally by the two translational movements of the tool, which is arranged in its initial position within the protective and guiding device. For this it is not necessary, the protection and guide device together with the drive unit in a not for it create provided angle. It is sufficient if the protective and guiding device is arranged flat on a support, for example on a window sill or on a window frame.
  • the drive unit for example by a arranged on the drive unit handle, a relative movement between the protective and guide means and the drive unit can be exercised, the movements being predetermined by arranged scenes. It can be provided that the relative movement against a predetermined force, such as a spring force, must be exercised.
  • a predetermined force such as a spring force
  • the protection and guide device is guided against a stop and predetermined by guiding the drive unit, the direction of the tool.
  • the links formed as linear guides are arranged perpendicular to each other, so that either either the tool in a direction translational or in the other direction can be moved translationally, as needed. Due to the fact that two translational degrees of freedom are provided, the tool can be positioned as desired within the plane defined by linkages (in this case linear guides).
  • the scenes extend perpendicular to the longitudinal extent of the regions of the outlet opening, wherein the two regions of the outlet opening almost correspond to the side walls of the cuboid protective and guide device.
  • the respective adjacent side walls form this outlet opening.
  • first guiding the device along the one link for example spatially horizontally
  • second guiding the device along the further link for example spatially vertically
  • the tool is movable so that it can at least partially escape at least at two mutually adjacent areas of an outlet opening of the preferably cuboidal protection and guide device.
  • the invention proposes to form the two levels like a slide and each to be provided with linear guides, which are arranged perpendicular to each other. Optionally, any position can be locked in one direction.
  • the protective and guiding means comprise side walls which are removable from the protective and guiding means. In this way, a quick tool change can be done.
  • the device according to the invention has a drive unit and a protective and guide device, wherein the drive unit comprises a motor having a drive spindle.
  • the drive spindle can be coupled to the drive shaft of the tool, which is arranged within the protective and guide device.
  • the drive spindle, the drive unit and the drive shaft of the protection and guide device are not coaxially.
  • these are optionally arranged with an offset in horizontal alignment and / or an offset in vertical alignment with each other.
  • Another significant advantage of the invention is that the user does not have to perform the relative movements by gripping the drive unit, comparable to the prior art. It is envisaged that in the region of the wall of the protective and guide device, coupled with the drive unit, a special grip device is provided, which allows the device to handle directly opposite to the cutting plane. This has considerable ergonomic advantages and in particular means that the tool can be guided in the defined directions easily and accurately and work safely.
  • a preferred embodiment of the housing device provides that the respective areas of the outlet opening are covered by flaps. These flaps open automatically as soon as the tool wants to emerge from the outlet opening. When not in use, the corresponding flaps offer a respective protection against injury and destruction of the tool.
  • a special embodiment provides that upon exit of the tool from the outlet openings, the respective position of the tool can be locked. This ensures that no additional force is required for further propulsion of the tool in only one direction, since working against the spring force caused by the safety device in the protective and guide device, eliminated. As soon as the inventive device is raised, the lock automatically releases, so that any regulations are taken into account by moving the tool back into the protective and guide device when lifting the device from a working surface. In a corresponding overrun the tool is thus completely surrounded by the housing device and not accessible to the user.
  • At least one suction device is provided opposite the respective regions of the outlet opening.
  • the suction device is advantageously designed such that one known from the prior art Vacuum cleaner tube can be plugged in a simple manner. This can also remove the dust generated by the processing.
  • the protective and guide device is provided with a flange, via which the drive unit can be coupled to the protective and guide device. Further, a rotational degree of freedom between the drive unit and the flange may be provided, which arbitrarily includes each angle. Locking in a defined position is also possible.
  • the drive unit can be arranged at different angles to the protection and guide device, so that depending on the application, the arrangement can be made accordingly.
  • different drive units for example in different lengths or even in different performances, can be coupled to the protective and guide device.
  • the protective and guiding device or the device comprises a laser pointer. This offers the advantage that during processing the user can be shown the optimum cutting guidance, for example in the form of a processing line or in the form of a target point.
  • the invention also has the advantage that the distance between the tool and a lateral stop, usually formed by the protective and guiding device, is extremely low. This makes it possible to perform the processing very close to the stop.
