Definitions

  • the invention relates to an additional handle for a power tool, which can be clamped to a clamping neck of the power tool.
  • additional handles are used, for example, in impact drills and rotary hammers to make it easier to guide the machine.
  • a one-piece plastic additional handle is known from the AEG company, which can be fixed to or removed from the clamping neck by means of a screw. The machine must be put down to operate the screw. In any case, the screw cannot be operated with the hand holding the handle. By tightening the screw, a movable depth stop rod is fixed at the same time.
  • the longitudinal axis of the handle intersects the central axis of the neck.
  • the one-piece construction has a jagged contour for manufacturing reasons.
  • the object of the invention is to propose an additional handle that is inexpensive to manufacture and in which an adjustment of the handle position relative to the Power tool is possible without having to take your hand off the handle or the other hand is necessary for this.
  • the user with the hand holding the grip part can fix and detach the additional handle by turning the clamping neck and can change the grip position of the additional handle on the clamping neck. He does not have to put the machine down or use the other hand. Due to the two-part design of the upper part and middle part, which clamps the clamping neck, the additional handle can be securely and securely clamped with high clamping force. An expensive steel band is not necessary.
  • the three-part design (handle part, upper part, middle part) enables inexpensive production of a largely closed outer shape of the additional handle made of plastic.
  • the tension-causing screw-nut connection can be provided either between the upper part and the handle part or between the middle part and the handle part.
  • the upper part is pulled against the handle part and thus the tensioning neck during clamping, the central part being supported on the handle part.
  • the central part is pressed against the clamping neck and the upper part is held on the grip part.
  • the longitudinal axis of the handle part intersects the central axis of the clamping neck.
  • a receptacle is formed on the upper part and on the middle part, between which a depth stop rod can be clamped when the handle part is rotated. This ensures that when the additional handle is clamped on the clamping neck, the depth stop rod arranged on the additional handle is simultaneously clamped. When the tension is released, the seat of the depth stop rod also loosens so that it can then be adjusted.
  • the upper part preferably forms a closed ring which encloses the clamping neck and forms the clamping edge of the upper part on the upper side. A dimensionally stable design of the upper part is thereby achieved.
  • An electric machine tool (1) for example an impact drill or hammer drill, forms a clamping neck (2) with its housing. Its central axis is marked with M.
  • the additional handle (3) can be tightened on the neck (2).
  • the additional handle (3) has a handle part (4), a middle part (5) and an upper part (6).
  • the longitudinal axis of the handle part (4) is designated L (see Fig.1, Fig.2).
  • the longitudinal axis (L) and the central axis (M) intersect.
  • the handle part (4) is therefore not laterally offset with respect to the central axis (M) of the clamping neck (2).
  • the handle part (4) has a bead (7) at its upper end, in which a cylindrical recess (8) coaxial with the longitudinal axis (L) is formed with an annular rim (9).
  • a cylindrical extension (10) is formed on the central part (5) and fits into the depression (8).
  • the approach (10) goes over a stop edge (11) in the central part (5) in the rest.
  • the stop edge (11) is assigned to the ring edge (9).
  • the middle part (5) is rotatably guided in the recess (8) of the handle part (4) about the longitudinal axis (L), the middle part (5) with its stop edge (11) on the ring edge (9) of the Supported part of the handle (4) in the axial direction (L).
  • the central part (5) forms flat side walls (13) on both sides of its cavity (12), which end at the clamping edges (14).
  • the upper part (6) is ring-shaped (see FIG. 4) and forms a base (15) on the underside and a clamping edge (16) with webs (17) on the top.
  • the base (15) can be inserted into the cavity (12) of the central part (5) in the direction of the longitudinal axis (L), the base (15) then between the flat side walls (13) of the central part (5) about the longitudinal axis (L ) is guided non-rotatably.
  • a sheet metal nut (19) with a rectangular base (20) is pushed onto a base (18) of the base (15).
  • Guide stops (21) of the base (15) hold the sheet metal nut (19) on its rectangular base (20).
  • the sheet metal nut (19) in the upper part (6) is rotatably and axially fixed. In other versions, this can also be done in a corresponding manner.
  • a stiffening wall (22) is designed in the base (15) above the nut (19).
  • the nut (19) is assigned a screw (23) which extends in the longitudinal axis direction (L) through an opening (24) in the handle part (4), through the cylindrical extension (10) of the central part (5) and through an opening (25) of the bottom (18) to the mother (19).
  • the screw (23) it would also be possible to arrange the screw (23) on the upper part (6) and the nut (19) on the handle part (4).
  • Receptacles (26, 27) for a depth stop rod (28) are formed on the central part (5) and on the upper part (6), which protrude beyond the ring shape of the upper part (6).
  • a nose (29) is provided on the central part (5) and a corresponding recess (30) is provided on the upper part (6).
  • the clamping edges (14, 16) each extend almost 180 around the clamping neck (2) in order to be able to clamp it firmly. It would also be possible for the clamping edge (14) or the clamping edge (16) to extend by less than 180 and for the other clamping edge to engage around the clamping neck (2) at a correspondingly larger angle. Preferably, the clamping edges (14, 16) together should encompass the clamping neck (2) as much as possible by almost 360.
  • the handle part (4), the middle part (5) and the upper part (6) are each one-piece, easily manufactured plastic parts that can be connected with two simple metal parts, namely the nut (19) and the screw (23) are.
  • the assembly of the described additional handle is simple.
  • the nut (19) is inserted into the base (15) of the upper part (6) and the screw (23) is fixed in the handle part (4).
  • the handle part (4), the middle part (5) or the upper part (6) are put together and by turning the handle part (4) the screw (23) is screwed into the nut (19).
  • the depth stop rod (28) can then be pushed between the receptacles (26, 27).
  • the user pushes the additional handle (3) onto the clamping neck (2) of the power tool (1).
  • it rotates the handle part (3), the clamping edge (16) of the upper part (6) pressing against the clamping neck (2), which is supported on the clamping edge (14) of the grip part (4)
  • Middle part (5) presses.
  • the additional handle (3) is thus held against rotation on the clamping neck (2).
  • the user can easily change the position of the additional handle (3) relative to the power tool (1) or the position of the depth stop rod (28) by twisting it with the hand holding the handle part (4) so that the connection loosens and he Can perform adjustment. He can set the new position again by turning it accordingly.
