Definitions

  • the invention relates to a holder for a hand belt sander for stationary operation, with a frame in which the hand belt sander can be detachably attached and which creates a vertical and a horizontal footprint for the hand belt sander.
  • the invention has for its object to provide a holder for a hand-held belt sander, which enables a stable mounting of a hand-held belt sander in stationary operation, which is easy to handle, enables simple attachment of the hand-held belt sander and which also does not impair the machining of large workpieces.
  • the invention is that an angle is provided as a frame, the two legs forming a right angle to each other each form a standing surface, the first leg, which forms the standing surface for vertical operation, is designed so that it does not have the working surface formed by the sanding belt protrudes when the hand belt sander is mounted.
  • a frame which is designed as an angle, can be swiveled from a horizontal to a vertical position simply by tilting and thus offers the possibility of placing the hand-held belt sander very easily in one of the two positions.
  • the angle can be designed to be stable and correspondingly heavy, so that it has a good stability when it is placed on a work surface or the like. offers.
  • the fact that the first leg, which is designed as a standing surface for vertical operation does not protrude beyond the working surface formed by the grinding belt, makes it possible to machine large surfaces without hindrance.
  • the hand-held belt grinder can essentially be held and supported solely by these support surfaces. It is then sufficient to provide only a screw to fix the position, so that the assembly of the hand-held sander in the holder is very simple.
  • the width of the legs corresponds approximately to the width of the hand-held belt sander and that two bearing jaws are provided on one leg (second leg) to support the motor housing.
  • These bearing jaws each advantageously form a support point for vertical and horizontal operation and are provided with rubber buffers or the like at the support points of the motor housing. Mistake. This supports the hand belt sander directly on its heaviest part, the motor housing and can therefore be stored reliably. The rubber buffers at the support points then serve to dampen vibrations. While the bearing jaws are formed in the second leg, it is sufficient to form a support that creates an indentation on the first leg as a support surface.
  • the hand strap ladder can lay down on this support, for example, with the front of its handle.
  • the fixing screw can then also establish the connection to the holder there.
  • the indentation is advantageously provided in such a way that it can accommodate the head of the fixing screw in such a way that it does not protrude beyond the contact surface formed by the first leg. This measure ensures that the head of the fixing screw does not hinder the installation for vertical operation.
  • At least one support for an additional device which can be screwed on and creates a stop surface on the grinding belt surface is provided on the bracket.
  • This removable stop surface can then be screwed to the angle, for example, so that it makes it possible to securely guide a workpiece to be machined over the working surface of the grinding belt.
  • this carrier is formed by an element which is molded onto the angle and protrudes laterally beyond the contour of the angle.
  • a plate that creates a work surface and surrounds the work surface of the grinding belt is pivotally attached to the free end of the first leg. This plate can then also be removably attached and can create a large work surface.
  • the angle itself in relation to a work surface.
  • the two legs are provided with bores and depressions for attaching a screw clamp, by means of which the angle can be clamped onto a work surface.
  • the bracket can be very firmly connected to a shelf.
  • FIG. 1 An embodiment of a holder according to the invention is generally designated 1 in FIG. 1. It can be seen that the holder 1 is designed as an angle and has two legs 2 and 3, which are integrally connected to one another.
  • the first leg 2 forms a support surface 2a when the hand-held belt grinder is suspended in the holder and is to be operated vertically
  • the second leg 3 forms the support surface 3a when the hand-held belt grinder is to operate in horizontal operation.
  • On legs 2 and 3 are 3 and 4, adapted to the contours of the hand-held belt grinder to be accommodated.
  • These bearing surfaces are essentially the support 5 and the bearing jaws 4, on which the hand-held belt grinder is supported in the recorded position both in vertical and in horizontal operation.
  • the width of the legs 2 and 3 corresponds approximately to the width of the hand-held belt grinder, so that the two bearing jaws 4a and 4b (cf. FIG. 2) can be provided at a suitable distance. Holes 7 are provided in each of these bearing jaws 4a and 4b, in which rubber buffers 15 can be clamped.
  • the area of the support 5 creates an indentation 10, into which a screw can be received in the manner described further below, with which the hand-held belt sander to be attached can be screwed to the support 5.
  • a carrier 6 Projecting laterally beyond the contour of the holder, a carrier 6 is formed in one piece with the holder, which can be used for screwing on an additional device. If there is to be a particularly stable fastening option for the additional device, a similar or identical carrier can also be formed on the side 3b opposite the carrier 6 shown in FIG. 2, which, for example, ribs away from the leg 2 at the height of the carrier 6 formed attachment point can extend, which then an additional device can be supported and attached on two sides and thus particularly stable.
  • the two legs 2 and 3 additionally connect a cross strut 25, which can also serve for locking and as a stop for the handle of a hand-held grinder.
  • FIG. 3 shows how a hand-held belt sander 14 is received in the holder according to the invention.
  • the bracket is shown in cross section.
  • the bearing jaws 4 form the support points 9a and 9b, with rubber buffers 15 damping the transmission of vibrations to the holder during operation of the hand-held belt sander.
  • the fixing screw 17 is provided, which is inserted in the area of the support 5 from the standing surface 2a (for the vertical operation shown in FIG. 4) into the indentation 10 created and there the handle 21 of the hand-held belt grinder against Support 5 braced.
  • the indentation 10 is designed such that the head 17a of the fixing screw 17 can be received in the indentation 10 such that it does not protrude beyond the surface 2a.
  • This working position shown in FIG. 3 corresponds to the operation in which the hand belt sander 14 creates a horizontal working surface.
  • it can be clamped with the aid of a clamping clip 12 which engages in a corresponding recess 8 (cf. also FIGS. 1 and 2).
  • the first leg 2 of the holder is designed such that it does not protrude beyond the working surface E-E formed by the grinding belt when the hand belt sander 14 is picked up. This ensures that parts of the bracket do not hinder the free movement of larger workpieces across the grinder belt surface.
  • a worktop 18 is provided in the embodiment shown in Fig. 3, which is pivotally attached to the free end of the first leg 2 and forms a recess for the grinding belt, so that the worktop 18 Sanding belt surrounds.
  • the worktop 18 is supported on the screw 19 at suitable points (hook 26 and slot 27) of the hand-held belt sander.
  • FIG. 4 shows the hand-held belt grinder accommodated in the holder according to the invention in a vertical working position, the configuration of the first leg 2 according to the invention also having an advantageous effect in this position, since longitudinal grinding of large surfaces is thus easily possible.
  • a device which is designated 22 as a stop, for the workpiece 23 is used it also enables different angles to be set, so that corresponding angles of inclination are also obtained on the workpiece.
  • This additional device 22 can also be unscrewed from the carrier 6 and anchored in a bore 27 on the hand belt sander, so that a stop surface is created transversely to that shown in FIG. 4. Then e.g. Process larger boards with a longitudinal guide.
  • the holder can be clamped on a work table 11 by means of a clamping clip 12.
  • a suitable bore 13 is provided for the clamp 12, which is attached to the free end of the first leg 2, into which the clamp engages.
  • Such holes are also provided at other suitable locations on the holder, so that there are various options for attaching the tensioning clip.
  • the center of gravity of the hand belt sander is held approximately in the central plane of the standing area formed by the first leg 2, so that a fairly stable condition can be achieved without the standing areas formed being very large have to.
  • This holder has the particular advantages that a hand-held belt sander can be easily picked up, that it is fixed at one point by a screw must and that a conversion from horizontal to vertical operation is possible in a very simple manner. Also parts of the holder do not hinder the movements of the workpieces to be carried out when grinding large-area workpieces, so that overall a handy and practical, stationary operation of a hand-held belt grinder with the holder according to the invention is made possible.
