Abstract
A suction device (11) for a hammer drill (6) has a first end (12) with a securing device (14) for securing the suction device (11) to the hammer drill (6) and a second end (13) opposite first end (12) and which has a contact area (15) with which the suction device (11) contacts a constructional component, the suction device (11) further having a receiving space (20) which at least partially encloses a working tool (7) of the pick power tool (6), and being provided with a connection device (18) for a vacuum source. A retaining element (21) having a through-opening (22) for the working tool (7) and a plurality of suction openings (23) is provided in an area (19) of the second end (13).
Claims6
A suction device for a pick power tool (6), comprising a receiving space (20) which at least partially encloses a working tool (7) of the pick power tool (6);
- a securing device (14) provided at a first end (12) of the suction device (11) for securing the suction device (11) to the pick power tool (6);
- a contact area (15) provided at a second end (13) of the suction device (10) opposite the first end for contacting a constructional component, a connection device (18) for a vacuum source;
- and at least one retaining element (21;
- 31;
- 41;
- 51) having a through-opening (22;
- 32;
- 42;
- 52) for the working tool (7) and at least one suction opening (23;
- 33;
- 43;
- 53) provided in an area (19) of a second end (13) of the suction device (11) opposite the first end (12), wherein the retaining element (21) has a plurality of segments (26) extending from an outer circumference of the suction device (11) to the through-opening (22) for the working tool (7), wherein the segments (26) are arranged at a distance from one another to form the at least one suction opening (23), and wherein the segments (26) are trapezoidal in outline and are constructed so as to taper in direction of the through-opening (22).
A suction device for a pick power tool (6), comprising a receiving space (20) which at least partially encloses a working tool (7) of the pick power tool (6);
- a securing device (14) provided at a first end (12) of the suction device (11) for securing the suction device (11) to the pick power tool (6);
- a contact area (15) provided at a second end (13) of the suction device (10) opposite the first end for contacting a constructional component, a connection device (18) for a vacuum source;
- and at least one retaining element (21;
- 31;
- 41;
- 51) having a through-opening (22;
- 32;
- 42;
- 52) for the working tool (7) and at least one suction opening (23;
- 33;
- 43;
- 53) provided in an area (19) of a second end (13) of the suction device (11) opposite the first end (12), wherein the retaining element (31) is formed by a grating portion which has the through-opening (32) for the working tool and whose meshes (36) form the suction openings (33).
A suction device for a pick power tool (6), comprising a receiving space (20) which at least partially encloses a working tool (7) of the pick power tool (6);
- a securing device (14) provided at a first end (12) of the suction device (11) for securing the suction device (11) to the pick power tool (6);
- a contact area (15) provided at a second end (13) of the suction device (10) opposite the first end for contacting a constructional component, a connection device (18) for a vacuum source;
- and at least one retaining element (21;
- 31;
- 41;
- 51) having a through-opening (22;
- 32;
- 42;
- 52) for the working tool (7) and at least one suction opening (23;
- 33;
- 43;
- 53) provided in an area (19) of a second end (13) of the suction device (11) opposite the first end (12), wherein the retaining element (61) has a plurality of ribs (66) which are spaced apart from one another and extend from an outer circumference of the suction device (11) to the through-opening (62) for the working tool (7), wherein each of the ribs (66) has a contact edge (67) with which the suction device (11) contacts the constructional component, wherein the contact edges (67) lie in a plane (F).
