- Elastomer spring element is formed. This allows a simple and inexpensive design of the handle device can be achieved.
- the secondary spring element is acted on only after a certain compression travel. It is proposed that the spring stiffness of the spring element formed by the leaf spring is adjusted so that with a compression travel between 2 mm and 10 mm, preferably between 3 mm and 7 mm, more preferably between 4 mm and 5 mm minimum operating pressure points for most important Use cases can be achieved. From this pressure threshold, the secondary spring element begins to act. The more the volume of the spring element
- Elastomer spring element is deformed at the deflection, the stiffer is a characteristic of the secondary spring element.
- Elastomer spring element is designed such that with an additional compression of 2 mm to 5 mm, in particular from 3 mm to 4 mm over a minimum operating pressure point beyond the elastomeric spring element is compressed to 70% of its original volume. In a further compression of 1 mm to 2 mm, virtually the entire volume of the elastomeric spring element is applied, so that the spring stiffness increases relatively quickly. This has the advantage that in a case on the Antivibrati- onshandgriff very much energy can be absorbed, so that the impact-like components are less loaded.
- Switch actuator comprises a commissioning of the drive device, wherein the
- Switch actuator can be switched both mono-stable and bi-stable between two switching positions.
- the term "bi-stableā is to be understood as meaning, in particular, that the switch actuator has two stable switching positions into which the switch actuator can be switched easy to assemble and cost design of the handle device can be achieved.
- the handle device comprises an intermediate plate which is provided in the machine housing and which accommodates at least the spring element unilaterally, and a control means by which the switch actuator cooperates with the mode switching device such that in certain operating modes the switch actuator is not bi-stable can be switched.
- the switch actuator only has a stable switching position, in which the switch actuator can be switched or in which the switch actuator preferably falls back automatically, while the switch operator in at least one other switching position of an operator in particular.
- control means is designed as a drawstring.
- the drawstring may preferably be made of a plastic or other material that appears appropriate to a person skilled in the art.
- the tension band preferably has an at least substantially rectangular cross section with an at least substantially circular-like, in particular circular middle fiber. It is also conceivable for the middle formers to have an at least essentially four- or hexagonal or another cross-section which appears expedient to a person skilled in the art.
- the middle fiber is preferably provided to serve at least partially as a filling channel, in particular during an injection process, and / or to form an advantageously narrow contact line with the leaf spring. As a result, an advantageous cost-effective design can be achieved.

- the u.a. shown assembly consists of the following functional units: an intermediate plate 26, the spring element 18 and a slide valve assembly.
- the intermediate plate 26 is the central component of this assembly. Their structure allows a number of possibilities for the simple implementation of existing functions in the hand tool 10 formed by the hammer when using the anti-vibration handle 58 and a mechanical switch operation with switching.
- One of the central tasks of the intermediate plate 26 is the receiving and guiding of the spring element 18, as shown in Figures 3a and 3b.

- a rectangular cross section with an aspect ratio of 1: 10 combined with a substantially circle-like, in particular circular, middle fiber was selected (see FIGS. 7a to 7c), but it is also possible for cross sections with rounded corners and / or deviating aspect ratios. in particular in the range between 1: 2 to 1: 20, particularly preferably from 1: 5 to 1: 15 be advantageous.
- the substantially circle-like, in particular circular portion serves to fill the mold in the manufacturing process and at the same time advantageously increases the strength.
- a buffer is created by the installation situation in the slide switch 66, which can compensate for all the blurring of manufacture and mechanical behavior of the tension band 30, which is made of plastic.
- the drawstring 30 must have a body for receiving the compensation spring 68 and safely taken up with the help of two rotational recordings in the slide valve 66 / performed.

- the labyrinth 70 engages the transitions into the surrounding parts and, especially during the switching of the switch actuator 24 formed by the hammer switch, effectively ensures dust protection and safe operation. Additional sealing elements are not required.
- Another aspect of the invention relates to the fact that with larger and more powerful hand tool machines 10, such as e.g. in heavy drilling and
- the above-described fixation of the leaf spring 32 between the anti-vibration handle 58 and the machine housing 20 is no longer sufficient.
- the leaf spring 32 is no longer sufficient as the sole spring element.
- Additional secondary spring elements 34 must still be introduced between the machine housing 20 and the leaf spring 32 in order to support the too soft leaf spring 32 in its spring action.
- the secondary spring elements 34 are each formed by an elastomeric spring element 36.
- the leaf spring can be acted upon by a clamping piece and the screw plate only on the back side functionally or with forces. On the side of the leaf spring facing the device side, no holding or fixing functions or forces can be introduced.
- the invention thus represents an extension of the known from the document DE 10 2006 029 630 A1 solution to implement the presented there anti-vibration handle concept even with larger and more powerful hand tool machines can.
- the operator-held anti-vibration handle 58 includes the switch actuator 24 formed as an on-off switch, and is closed by screwing a handle of the anti-vibration handle 58 rearward.
- the leaf spring 32 is clamped between the anti-vibration handle 58 and two screw plates 48.
- the two screw plates 48 are pushed in the transverse direction on both sides of the leaf spring 32.
- the screw plates 48 thus enclose an upper clamping region 50 of the leaf spring 32 up to the contact zone to the anti-vibration handle 58 in all spatial directions. This ensures a durable and stable enclosure of the leaf spring 32.
- screw dome 52 which serve for screwing the screw 48 and thus an attachment of the leaf spring 32 with the anti-vibration handle 58.
- the screw plates 48, the leaf spring 32, the anti-vibration handle 58 and a strained bellows 72 form a fastening system, which is held together advantageous form and adhesion.
- the positive connection is formed by mutually supporting and penetrating retaining domes and ribs, so that the adhesion has only a fixing function and the essential forces are absorbed by the positive connection of the components.
- a significant advantage of the screw plates 48 pushed on both sides is the provision of additional functional surfaces in front of a region and laterally of a region of the screw plates 48 of the leaf spring 32.
- the screw plates 48 are formed so that they can accommodate the additional secondary spring elements 34.
- the screw 48 have additional functions.
- the screw plates 48 In order to prevent tearing out of the anti-vibration handle 58 and thus also overloading of the leaf spring 32, the screw plates 48 have lateral abutment surfaces which are supported on the back on two rear plates 38 designed as housing rear plates. As a result, the anti-vibration handle 58 has a stable and defined back stop.
- Another function of the screw 48 is the lateral guiding and covering the control means 28 formed by the tension band 30 relative to that of a
- Elastomer formed secondary spring element 34 With the drawstring 30 of the switch actuator 24 formed by the on-off switch is blocked during a M formulateeins so that the operator does not press the switch actuator 24 constantly. The drawstring 30 must be able to slide smoothly on the leaf spring 32 and must not be jammed or pinched.
- the tension band 30 is chambered in a slot of the screw 48.
- the bellows 72 is chambered by the screw plates 48 in the anti-vibration handle 58.
- the screw 48 also form the end stop in the longitudinal and vertical directions of the anti-vibration handle 58th
- the lower Blattfederklemmung has been integrated into the screw system of the back plates 38 to the machine housing 20 advantageously (see Figures 14a and 14b).
- the previously one-piece backplate was split into two mirror-symmetrical backplates 38 in order to fulfill all required functions, favorable mountability and mold endformability.
- the bellows 72 already mounted on the antivibration handle 20 and the rocker arms are chambered during assembly by pushing the two back plates 38 together. Due to the required bias of the leaf spring 32, the leaf spring 32 is then a bit of the back plates designed as housing rear plates 38 from.
- a spring plate 40 is inserted above with its two retaining ribs 42 in two corresponding retaining grooves 44 formed as housing rear plates back plates 38 and then folded against a leaf spring tension in the direction of the back plates 38 to the rear ,
- two snap hooks 46 are integrated in the back plates 38, which engage in the spring plate 40 and hold them in the mounting position.
- the leaf spring 32 For clamping the leaf spring 32 both positive and positive elements are used. As a positive connection, the leaf spring 32 has at its lower end two openings and a Abfalzung 74.
- the leaf spring 32, the spring plate 40 and the machine housing 20 are threaded onto two domes of the respective side of the back plates formed by the housing rear plates 38. Furthermore, the spring plate 40 engages around the two screw domes of the machine housing 20.
- the Abfalzung 74 of the leaf spring 32 is clamped between the back plates 38 and the spring plate 40.
- the spring plate 40 is designed in its contour height so that the leaf spring 32 is firmly clamped down to about 25% of its length. The remaining length can cantilever freely during compression.
- Another aspect of the invention is the combination of the leaf spring 32 as the primary spring element and the at least one further secondary spring element 34, which is acted upon only after a certain compression travel.
- Figure 15 shows a cross section through the upper portion of the anti-vibration handle
- the screw plates 48, with which the leaf spring 32 is enclosed, are forwardly formed so that they can still receive one or the additional secondary spring elements 34.
- a foamed elastomer molding is inserted between the screw plate 48 or the leaf spring 32 and the spring plate 40.
- Elastomer molding is formed as the elastomeric spring element 36 and forms the secondary spring element 34.
- Foamed elastomer moldings have the advantage of cost-effective production by a continuous extrusion molding process with subsequent cutting to the required length. Furthermore, they act in virtually all spatial directions, i. they have no preferential direction, e.g. a helical compression spring.
- the advantageous, formed as Elastomerfederelement 36 secondary spring element 34 supports the leaf spring 32 at loads that are above an optimal Radio Santikticians.
- the optimum operating pressure point is the minimum pressure that the operator just has to provide in order for the hand tool 10 formed by the hammer to perform a regular and clean impact operation. This operating pressure depends on the performance class of the hand-held power tool 10 and the particular application.
- the spring stiffness of the leaf spring 32 be set so that the minimum operating pressure points for most important applications are achieved with a compression travel between 2 mm and 10 mm, preferably between 3 mm and 7 mm, particularly preferably between 4 mm and 5 mm , From this Antikschwelle the secondary spring element 34 starts to act.
- a volume compression of the elastomeric spring element 36 is designed such that with an additional compression of 2 mm to 5 mm, in particular from 3 mm to 4 mm beyond the minimum operating contact point, the
- Elastomer spring element 36 is compressed to 70% of its original volume. With further compression of 1 mm to 2 mm, almost the entire volume of
- Elastomer spring element 36 acted upon, so that the spring stiffness increases relatively quickly. This has the advantage that in a case on the anti-vibration handle 58 a lot of energy can be absorbed, so that the impact-like components are less loaded. A described compression characteristic can also be effected or supported by a targeted shaping of the elastomer spring element 36. It is thus also possible to install tubular or other contours that can be generated in one extrusion process.
- the elastomer spring element 36 is preferably made of foamed elastomer (sponge rubber), which is produced in a continuous extrusion molding process with subsequent cutting to length
