- Machine housing 20 movably arranged tool holder 54 for changeable receiving an insert tool 16 and with a received in the machine housing 20, a drive unit and a gear unit having drive device 14 for driving the insert tool 16 in different modes.
- the tool holder 54 is preferably rotatably arranged on an end face of the machine housing 20.
- a handle device is further provided in the example of Figure 1 further.
- the handle device comprises in the present example a switch actuator 24 for commissioning the drill and / or chisel hammer.
- the switch actuator 24 can be switched both monostable and bi-stable between two switching positions.
- an additional handle device 56 is arranged on the machine housing 20 of the drill and / or chisel hammer, in particular arranged adjustable.
- the hand tool 10 has an operating mode switching device 12.
- an operating lever for operating mode switching is arranged on the machine housing 20, with which an operator can choose between different types of drive for the insert tool 16 inserted in the tool holder 54.
- the handle device for the portable power tool 10 comprises a spring element 18 and a handle unit 22 which is attached to the machine housing 20 in a manner of limited mobility and which is vibration-decoupled from the machine housing 20 via the spring element 18 and comprises the switch actuator 24 for commissioning the drive device 14.
- the handgrip unit 22 comprises an anti-vibration handle 58.
- the handheld power tool device further comprises a control means 28, via which the switch actuator 24 cooperates with the mode changeover device 12 in such a way that in certain operating modes Switch actuator 24 can not be bi-stable switched.
- the control means 28 is designed as a drawstring 30.
- the assembly shown inter alia in Figure 2 is composed 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.
- the spring element 18 is clamped by the intermediate plate 26 in the anti-vibration handle 58 and fixed at the clamping point over a contour.
- the contour is preferably realized in a contact surface on the intermediate plate 26, on which the spring element 18 can be supported. The curve of this contour determines stiffness, bending line and paths of the
- the spring element 18 is formed as a leaf spring 32.
- intermediate plate 26 serves to receive or as a stop for one or more secondary spring elements 34, 34 ', 34 ", which can serve as damping elements
- pockets with supporting ribs 60 and a frame 62 additionally provide for the introduction of damping elements into the intermediate plate 26.
- the secondary spring elements 34, 34 ', 34 may preferably be made from this Foam, a cellular rubber, a sponge rubber, another synthetic or natural foam, elastomer, TPE, rubber, a gel or a similar elastic material may be formed.
- the degree of damping or suspension can also be adjusted via the volume of individual chambers.
- the frame 62 prevents jamming with other surrounding components.
- the particular embodiment of the intermediate plate 26 also allows improved guidance of the power tool 10 and in particular an improved transmission of operating forces on the anti-vibration handle 58 on the machine housing 20 of the power tool 10.
- Figure 5 are in the upper part of a handle housing 64 and at the connection to the one Motor support assembly comprising 14 support points and recordings of the intermediate plate 26 designed so that along the power flow from the anti-vibration handle 58 operating forces unfiltered or unsprung can be transferred to the power tool 10. This results in a good control of the hand tool 10.
- the intermediate plate 26 is provided in the machine housing 20 and receives the spring element 18 on one side. Finally, in the intermediate plate 26, the slide valve assembly is added The slide valve assembly consists of 6a to 6c of a slide 66, the drawstring 30 and a compensation spring 68. In addition to the intermediate plate 26 forms another important unit especially in the transmission of switching or Switching paths to the switch actuator 24.
- the control means 28 designed as a tension band 30 is made of plastic.
- the z-shaped, cranked slide switch 66 can be pushed into the intermediate plate 26 with a simple sliding movement and locked in place by means of a snap hook connection, not shown, in the intended installation position. It is also conceivable that the z-shaped, cranked slide switch 66 can rotate into the intermediate plate 26 with a simple pivoting movement.
- the aspect ratio of the guide surfaces ensures sufficient pre-centering during the entire pre-assembly. A wrong assembly is thereby excluded.
- plastic offers a great variety of variations in order to combine low friction values with good emergency running properties and low dust susceptibility. Therefore, a plastic is fundamentally a very suitable material for this application.
- a band cross section of the tension band 30 must be very flat in height and long in the width.
- a rectangular cross-section with an aspect ratio of 1: 10 combined with a substantially circle-like, in particular circular, middle fiber was chosen (see FIGS. 7a to 7c), but cross-sections with rounded corners and / or deviating aspect ratios, in particular in FIGS Range between 1: 2 to 1: 20, more preferably from 1: 5 to 1: 15 be advantageous.
- a buffer is created by the installation situation in the slide valve 66, which can compensate for any 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 slide valve 66 supports the compensation spring 68 on the opposite side and determines the measure of the compensation over the installation length.
- the path from the slide valve 66 is now transmitted force-dependent on the drawstring 30 and the switch actuator 24 (see Figures 8a and 8b).
- the coupling is no longer rigid but linear-elastic.
- the paths between the slide valve 66 and switching lever on the switch actuator 24, which forms a hammer switch, are designed so that a reserve is always kept in the compensation spring 68.
- This reserve from the length of the compensation spring 68 in operation can be used for tolerance compensation and compensation of thermal, elastic as well as plastic changes in length on the drawstring 30, which is made of plastic. It is an overload protection ensured and now defined by the compensation spring 68 tensile forces applied to the drawstring 30.
- a labyrinth 70 is further provided over the intermediate plate 26, which in order to cover the housing comprising a striking mechanism housing and a housing housing 20, the engine assembly comprising a drive device 14 and the anti-vibration handle 58 inwardly reaches (see Figure 9).
- 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 chipping hammers, 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 one of the leaf spring 32 with the anti-vibration handle 58.
- the screw 48, the leaf spring 32, the anti-vibration handle 58 and a strained bellows 72 form a fastening system, which is held together advantageously on form and frictional connection.
- 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 an overload of the leaf spring 32, the screw plates 48 have lateral contact surfaces, which are supported on the back of two, designed as rear plates back plates 38. 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 Tieback 30 must be able to slide smoothly on the leaf spring 32 and must not be jammed or pinched.
- Bellows 72 is chambered by the screw plates 48 in the anti-vibration handle 58. Furthermore, the screw 48 also form the end stop in the longitudinal and vertical direction of the anti-vibration handle 58.
- the lower Blattfederklemmung is in the screw system of the back plates
- 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 anti-vibration handle 20 and the rocker arms (not shown) 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 , In order to hold this position, two are in the back plates 38
- Snap hooks 46 integrated, which engage in the spring plate 40 and hold them in the mounting position.
- the thus pre-assembled complete, designed as a handle assembly handle device can then be applied in an assembly line on the core device.
- 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 also surrounds 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.
- FIG. 15 shows a cross-section through the upper region of the anti-vibration handle 58 with the leaf spring 32 and the secondary spring element 34.
- the screw plates 48 which surround the leaf spring 32, are designed to receive the one or the additional secondary spring elements 34 can.
- a foamed elastomer molding is inserted between the screw plate 48 or the leaf spring 32 and the spring plate 40.
- the elastomeric molded part 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 yet has to provide, so that the hand tool 10 formed by the rotary hammer has a regular and clean impact operation performs. This operating pressure is dependent on the power class of the power tool 10 and the particular application.
- the spring stiffness of the leaf spring 32 is adjusted so that with a compression travel between 2 mm and 10 mm, preferably between
- 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
