Description of the embodiments

The hand tool (10) shown in the examples is an electrically operated hand tool. This has at least one drive device (12) comprising at least one electric motor (12a) with at least one motor shaft (12b) and at least one gear device (12c) coupled to the motor shaft (12b). In this case, the transmission device (12c) at least the implementation of a rotational movement of the motor shaft (12b) in a transverse movement along a machine axis defined by the axis (12d). The hand tool (10) can be designed as a chisel and / or hammer drill, wherein the drive device (12) for Actuation of a hammer impact mechanism (13) is used. Further examples of hand-held power tools (10) with at least one alternating drive between two end positions of a tool are impact wrenches, percussion drills, stab, foxtail or reciprocating saws.

In the FIG. 1 illustrated, hand tool (10) according to the invention comprises a machine housing (14) and a with the machine housing (14) connected to the handle (16). In the machine housing (14), the drive device (12) is arranged. The drive device (12) is indicated schematically here as a hammer impact mechanism (13). The handle (16) is connected via a spring element (18) with the machine housing (14). In further embodiments, the handle (16) additionally or alternatively via at least two spring elements and / or at least one, two or more damping elements with the machine housing (14) are connected.

In addition, the hand tool (10) according to the invention has a deflection system (20). The deflection system (20) comprises a first lever arm (22) and a second lever arm (24).

The first lever arm (22) is rigidly connected to the handle (16). Through an engagement opening (26) of the first lever arm (22) projects into the machine housing (14). In further embodiments, the first lever arm can also be connected elastically, rotatably and / or displaceably with the handle (16).

The second lever arm (24) of the deflection system (20) is arranged in the machine housing (14). In one, on the machine housing (14) supported pivot bearing point (28) of the second lever arm (24) is rotatably mounted. The movable compensating means (30) is designed as a counterweight (31). The counterweight (31) is arranged at the arm end (32) of the second lever arm (24) remote from the pivot point (28). The counterweight (31) is fixedly connected to the second lever arm (24).

The end of the first lever arm (22) reaching through the engagement opening (26) engages at a rotatable engagement point (34) on the second Lever arm (24) on. In this case, the rotatable engagement point (34) at a first distance A from the pivot bearing point (28) is removed.

In the following, the function of the hand tool (10) according to the invention will be explained. By the action of the drive device (16) acts as a repulsive force (35) designated reactive force (36) on the machine housing (14). The vibrations generated thereby preferably propagate along a major axis of vibration (38) in the machine housing (14).

By the spring element (18) of the handle (16) on the machine housing (14) is supported. The pivot bearing point (28) of the second lever arm (24) rigidly connected to the machine housing (14) follows a movement of the machine housing (14) directly. Due to its inertia, the movable compensating means (30) moves only delayed at the arm end (32) of the second lever arm (24) remote from the pivot point (28) of this movement. About the, at a second distance B from the movable compensating means (30) arranged, rotatable engagement point (34), the delayed movement is transmitted to the first lever arm (22). Since the first lever arm (22) is rigidly connected to the handle (16), a relative movement (40) is created between the handle (16) and the machine housing (14). By this relative movement (40) vibrations or vibrations with reduced amplitude are passed to the handle.

By dimensioning the movable compensating means (30), that is, the counterweight (31), a vote of the damping behavior with respect to the power tool (10) is possible.

About the division of the distances A and B, the effect of the movable compensating means (30) can be influenced during the design of the power tool (10). The distances A and B thus act as design parameters.

FIG. 2 shows a development of the hand tool of the invention (10) as a second embodiment. Same elements are the same name and provided with the same reference numbers. In this case, at a distance B from the rotatable engagement point (34), a third lever arm (42) rotatably connected to the arm of the pivot point (28) remote end (32) of the second lever arm (24). The third lever arm (42) is guided here two guide elements (44) parallel to the main axis of vibration (38). By varying the number of guide elements (44), in particular one, three or more guide elements (44), variants of the hand tool (10) according to the invention can be obtained. A development of the hand tool (10) according to the invention results from the use of bearing elements such as sliding, needle, roller or roller bearings to improve the friction properties of the guide elements (44).

The third lever arm (42) acts on the movable compensating means (30), designed here as a counterweight (31). According to a preferred embodiment, the counterweight (31) is fixedly connected to the third lever arm (42). In particular, in a further development of the portable power tool (10) according to the invention, the counterweight (31) and the third lever arm (42) can be made in one piece.

The guidance of the third lever arm (42) in the guide elements (44) ensures that the movable compensating means (30) is movable only in the direction of the main axis of vibration (38). As a result, it has a particularly efficient damping effect on vibrations along the main axis of oscillation (38).

A preferred further development of the hand tool (10) according to the invention is in FIG. 3 shown. The same elements are denoted the same and provided with the same reference numbers. At least two return (48) and / or damping elements (50) are arranged in the direction of the degree of freedom (46) of the movable compensating means (30). The restoring (48) and / or damping elements (50) thus act in the direction of the degree of freedom (46) on the movable compensating means (30). The return elements (48) are in FIG. 3 implemented in a particularly preferred form as spring elements (49).

Upon a deflection of the movable compensating means (30) from a rest position, the restoring elements (48) generate a restoring force FR on the movable compensating element (30). This tries to put the movable compensating means (30) in the rest position.

Damping elements (50), however, have a damping effect on the movements of the movable compensating means (30).

Variants of this exemplary embodiment of a handheld power tool (10) according to the invention result in particular by varying the number of reset (48) and / or damping elements (50), in particular to one, three, four or more reset (48) and / or damping elements (50 ). A particularly preferred variant results from the combination of at least one restoring (48) and at least one damping elements. Further embodiments result from varying the connection means of the restoring (48) and / or damping elements (50) to the movable compensating means or the machine housing. In particular, the restoring (48) and / or damping elements (50) can be firmly connected to the movable compensating means or the machine housing or rest only against them.

In FIG. 4 a further embodiment of a hand tool (10) according to the invention is shown, in which the movable compensating means (30) in the handle (16) is arranged. The same elements are denoted the same and provided with the same reference numbers. The handle (16) is supported on the machine housing via a first (18) and a second spring element (19).

Notwithstanding the preceding embodiments, the first lever arm (22) is rigidly connected to the machine housing (14). The handle (16) has a passage opening (52) through which the first lever arm (22) is guided into the handle (16).
The second lever arm (24) is pivotally mounted in a pivot bearing point (28) rigidly connected to the handle (16). The first lever arm (22) engages the second lever arm (24) in a rotatable engagement point (34). The rotatable engagement point (34) is arranged at a distance A to the pivot bearing point (28) on the second lever arm (24).

Variants arise in particular by selecting the connection of the first lever arm (22) with the machine housing and / or the second lever arm (24) with the handle. In particular, the connection can be made elastic, torsionally elastic and / or displaceable.

The movable compensating means (30) is disposed at an arm end (32) of the second lever arm (24) remote from the rotatable engagement point (34).

Analogous to the embodiments described above, the drive device (16) generates a reactive force (36) which sets the machine housing (14) in motion. The first lever arm (22), which is essentially rigidly connected to the machine housing (14), transmits this movement to the pivotably suspended second lever arm (24). Due to the arrangement of the rotatable engagement point (34) on the one hand and the movable compensating means (30) on the other hand, viewed from the pivot bearing point (28), the direction of movement on the movable compensating means (30) is reversed relative to the movement of the machine housing (14).

Deviating from the previous embodiment is in FIG. 5 an embodiment shown in which the second connection between the handle (16) and the machine housing (14) via a pivot axis (54) is realized. Further advantageous embodiments result from elastic mounting of the pivot axis.

This in FIG. 6 embodiment shown combines the embodiment FIG. 4 with two return (48) and / or damping elements (50). The reset (48) and / or damping elements (50) act in an analogous manner on the movable compensating means (30), as already in the exemplary embodiment FIG. 3 described. Also analogous developments of the hand tool of the invention (10) as in the description FIG. 3 possible.

In FIG. 7 is an embodiment according to FIG. 5 shown, which is supplemented by two restoring (48) and / or damping elements (50). The Operation of the return (48) and / or damping elements (50) is as previously described. In addition, the movable compensating means (30) is displaceably mounted on a rigid and straight guide rail (56). The second lever arm (24) engages a pivot bearing (58) on the movable compensating means (30). If the second lever arm (24) pivots about the pivot bearing point (34) due to a reactive force (36) acting on the first lever arm (22), the movable compensating means is displaced along the guide rail (56). Further developments of the guidance of the movable compensating means (30) are possible by means of special, for example hyperbolic or parabolic, and / or non-rigid guide rails (56).

The FIGS. 8a and 8b show two embodiments of another embodiment of a hand tool of the invention (10). Notwithstanding the embodiments described above, the first lever arm (22) and the second lever arm (24) by at least one thrust-pivot gear device (60), in particular, for example, a rack-and-pinion gear or a push rod-friction gear, interacting with each other. In this case, the first lever arm (22) on a thrust element (62), in particular, for example, a Zahnungsstrecke or Reibstrecke on. This thrust element (62) is arranged on the side of the first lever arm (22) facing the movable compensating means (30). The second lever arm (24) is preferably fixed to a pivoting element (64), here in particular as a circular (64a, Fig. 8a ) or cycloids (64b, Fig. 8b ) Gear or friction wheel, connected. The pivoting element (64) is rotatably mounted about a fixed, preferably rigidly connected to the handle (16) pivot axis (66).

Analogous to the embodiments described above, the drive device (16) generates a reactive force (36) which sets the machine housing (14) in motion. The first lever arm (22) substantially rigidly connected to the machine housing (14) transmits this movement via the push-pivot gear device (60) to the second lever arm (24). By the pivot axis (66) opposite arrangement of the thrust-pivot gear device (60) on the one hand and the movable balancing means (30) on the other hand, the movement direction is on movable compensating means (30) relative to the movement of the machine housing (14) vice versa.

The damping effect of the movable compensating means (30) is in this arrangement, inter alia, by the distance B of the movable compensating means (30) from the pivot axis (66) and by the distance A between the pivot axis (66) and the effective range (68) of the thrust Swivel transmission device (60) determined. Furthermore, the effect of the movable compensation means (30) can be influenced by the design of a non-circular pivot member (64b).

Further developments of these embodiments result from additions and combinations with features of the preceding embodiments, in particular by combination with restoring (48) and / or damping elements (50), which act on the movable compensating means (30), and / or supplementing a third lever arm ( 46) and / or a guide rail Fig. 7 ,

In the FIGS. 9a and 9b is a further embodiment of a hand tool according to the invention with at least one thrust-pivoting gear device (60) between the first lever arm (22) and the second lever arm (24), wherein the movable compensating means (30) in the machine housing (14) is arranged. Here, the first lever arm (24) and the movable compensating means (30) on one and the same side of the pivot axis (66) are arranged. For this purpose, the thrust element (62) away from the movable compensating means (30). The second lever arm (24) is fixed, preferably rigidly connected to a pivoting element (64) of the push-pivot gear device (60). In this case, the pivoting element (64) has a circular (64a, Fig. 9a ), cycloids (64b, Fig. 9b ) or other shape.

In its operation, these embodiments correspond to the embodiments Fig. 8a and 8b ,

Further developments of these embodiments result from additions and combinations with features of the preceding embodiments, in particular by combination with restoring (48) and / or damping elements (50), which act on the movable compensating means (30), and / or supplementing a third lever arm (46) and / or a guide rail Fig. 7 ,

By further, alternative arrangements with at least two, preferably three or four, lever arms which effect a deflection of a reactive force acting on the machine housing (14) onto a movable compensating means (30) such that the movable compensating means (30) dampens the movement of the handle (16) acts, further advantageous developments and additions of the hand tool (10) according to the invention are possible.

In some cases, an arrangement similar to the embodiment may FIG. 7 with a not rigidly, but movably connected to the movable compensating means (30) second or third lever arm (24, 42) prove to be advantageous. In addition to the embodiment shown in this embodiment, further connection variants of the movable compensating means (30) with the second or third lever arm (24, 42) acting on the movable compensating means (30), such as a toothing or alternative form-fitting connection, are conceivable.

Alternatively or additionally, based on cable and / or Bowden cables and / or pneumatic and / or hydraulic elements, a suitable, inventive deflection system (20) build up.

FIG. 10 shows a hand tool (10) according to the invention, in which the deflection system (20) is constructed on a cable pulling device (68). The cable pull device (68) comprises at least one, preferably two, three or more deflection rollers (70). The deflection rollers (70) are rotatably mounted in the handle via a respective axis of rotation (72), wherein the axes of rotation (72) are fixed, preferably rigidly connected to the handle. Furthermore, the cable pull device (68) comprises a tension element (74), here designed as a pull cable (74a). This is preferably firmly connected with its first cable end (76) with the machine housing (14). In the present example, the first end of the rope (76) attached to a mounting lug (78) on the machine housing (14). At a second end of the rope (80), the movable compensating means (30) is preferably fixedly connected.

In addition, the cable pull device (68) has a restoring element (82), designed here as a return spring (82a). The restoring element (82) is arranged between an inner end face (84) and the movable compensating element (30) such that upon the occurrence of a tensile force FZ on the traction cable a restoring force FR acts on the movable compensating means. In a preferred embodiment, the return element (82) is ideally biased so that when moving the machine housing (14) due to a reactive force (36), the movable compensating means (30) can perform a compensating movement in the opposite direction.

Extensions and / or alternative embodiments of the embodiment according to Fig. 10 arise by varying the attachment of the cable ends (76, 80), in particular with fastening hooks, fastening bushings and / or similar fasteners. In addition, modifications by varying the number of deflection rollers (70), in particular one, three, four or more deflection rollers (70), and / or the cable guide are possible.

When using a Bowden cable and / or a train-push chain as a tension element (74) can be dispensed with a return element (82).

Furthermore, a deflection system (20) according to the invention with a cable pulling device (68) analogous to the embodiment Fig. 10 to an arrangement of the movable compensating means (30) are used in the machine housing and / or with other hand concept shapes and / or - fasteners, in particular with the second spring element (19), as a variation of the example Fig. 10 to be obtained.

In FIG. 11 a further embodiment of a hand tool according to the invention with a deflection system (20) is shown, which is constructed as a pressure-body system (86). In the embodiment shown here is arranged the pressure-body system (86) in the handle (16). The pressure-body system (86) has a storage cylinder (90) and a pressure line (92). Furthermore, the pressure-body system comprises a compensating cylinder (94). The storage cylinder (90) encloses a storage volume (96). The balancing cylinder comprises a compensation volume (98). The storage volume (96) and the compensation volume (98) are connected to one another via the pressure line (92), the total volume being filled with a fluid (100), preferably a gas or a liquid, in particular hydraulic oil.

The storage volume (96) is limited on one side by an axially displaceable accumulator piston (102). The first lever arm (22) is preferably fixed, in particular in one piece, connected to the accumulator piston (102).

The compensating volume (98) is limited on one side by an axially displaceable compensating piston (104). This is fixed, preferably rigidly connected to the movable compensating means (30). In a preferred embodiment, the balance piston (104) is made in one piece with the movable compensation means (30).

On the compensating volume (98) opposite side of the balance piston (104) is a, preferably filled with air vent volume (106). This is connected to a throttle (108) with the environment.

If a reactive force (36) acts on the first lever arm (22) and thus on the accumulator piston (102) via the machine housing (14), the fluid in the accumulator volume (96) is compressed and displaced. The fluid deviates via the pressure line (92) into the compensation volume (98). As a result, the compensating piston (104) and thus the movable compensating means are displaced counter to the direction of movement of the machine housing (14). The air in the decreasing ventilation volume (106) can escape via the throttle (108). Similarly, a reversal of movement of the movable compensating means (30) relative to the machine housing (14) occurs in the event that a negative reactive force (36) acts on the machine housing (14). By selecting a suitable fluid (100), in particular a gas - for example air, or a liquid - for example an oil, the damping effect of a vibration damping according to the invention can be influenced. Furthermore, by dimensioning the volumes (96, 98, 106) and the pressure line (92) additional influence on the damping properties can be taken. In addition, the arrangement of a, in particular variable line throttle in the pressure line (92), the damping can be influenced. Finally, there is an additional tuning parameter in the dimensioning of the throttle (108). In particular, the throttle (108) can be made variable so that a control of the damping characteristic by users is possible.

Alternative embodiments of the embodiment according to Fig. 11 arise among other things by an arrangement in the machine housing. Combinations with other embodiments are also conceivable, in particular, at least one restoring (48) and / or damping elements (50), which acts on the movable compensating means (30), can be integrated in addition.

Further advantageous variants according to the invention can be obtained by dividing the movable compensating means (30) from preferably two, three, four or more partial elements (30, 31), in particular counterweights.
