  • the invention relates to a handle device for a hand tool according to the preamble of claim 1 and as from DE 10 2006 029 630 A1 known.
  • Anti-vibration handles with an elastic connection to the hammer also cause relative movements between the hammer and the handle itself due to the required stiffness.
  • the invention is based on a handle device for a hand-held power tool, which has an operating mode switchover device and a drive device for driving an insert tool in different operating modes, with at least one spring element and with a handle unit which is attached to a machine housing at least to a limited extent and which can be moved across the at least one spring element the machine housing is at least partially vibration-decoupled, and with at least one screw plate which is provided to fix the spring element in a positive and non-positive manner.
  • the handle device according to the invention with the features of main claim 1 solves the problem in an easy to install and inexpensive manner. It fulfills all the requirements placed on it.
  • the screw plate encloses a clamping area of the spring element in all spatial directions except for a contact zone with the handle unit. In particular, this enables a stable, high-quality, compact and inexpensive design and connection of the handle device to the hand-held power tool.
  • the screw plate have at least one screw dome, which is provided for screwing the spring element to the handle unit.
  • the handle device comprises a switch actuator for starting up the drive device, the switch actuator being able to be switched between two switching positions both mono-stably and bi-stably.
  • “bi-stable” is to be understood in particular to mean that the switch actuator has two stable switching positions into which the switch actuator can be switched.
  • the switch actuator is preferably formed as an on-off switch of the hand machine tool.
  • the handle device comprises an intermediate plate which is provided in the machine housing and which at least receives the spring element on one side, and a control means via which the switch actuator interacts with the operating mode switchover device in such a way that in certain operating modes the switch actuator is not switched bi-stably can.
  • “mono-stable” is to be understood in particular to mean that the switch actuator only has a stable switching position into which the switch actuator can be switched or into which the switch actuator preferably falls back automatically, while the switch actuator in at least one other switching position Operator in particular must be kept. As a result, an easy-to-assemble and inexpensive configuration of the handle device can be achieved.
  • the control means be designed as a tension band.
  • the drawstring can preferably be made of a plastic or another, a specialist be made as a material that appears reasonable.
  • the drawstring preferably has an at least substantially rectangular cross section with an at least substantially circular-like, in particular circular, central fiber.
  • the middle fastener it is also conceivable for the middle fastener to have an at least essentially quadrangular or hexagonal cross-section or another cross-section that appears reasonable to a person skilled in the art.
  • the middle fiber is preferably provided to serve at least partially as a filling channel, in particular in a spraying process, and / or to form an advantageously narrow line of contact with the leaf spring. This enables an advantageously inexpensive configuration to be achieved.
  • the at least one spring element is formed by a leaf spring. In this way, in particular a preferably inexpensive implementation and an advantageously simple assembly of the handle device can be achieved.
  • the handle device has at least one secondary spring element which is formed by an elastomer spring element.
  • the spring element formed by the leaf spring can advantageously be supported in a spring action and use of the handle device, in particular in larger and more powerful handheld power tools, can be achieved.
  • the secondary spring element is only acted upon after a certain spring deflection. It is proposed that the spring stiffness of the spring element formed by the leaf spring be set so that with a spring deflection between 2 mm and 10 mm, preferably between 3 mm and 7 mm, particularly 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 elastomer spring element is deformed during the deflection, the stiffer a characteristic curve of the secondary spring element.
  • the volume compression of the elastomer spring element is designed in such a way that with an additional deflection of 2 mm to 5 mm, in particular 3 mm to 4 mm, beyond a minimal operating pressure point, the elastomer spring element is 70% of its initial volume is compressed. With a further compression of 1 mm to 2 mm, the entire volume of the elastomer spring element is applied, so that the spring stiffness increases relatively quickly. This has the advantage that in the event of a fall on the anti-vibration handle, a great deal of energy can be absorbed, so that the components which are subjected to impacts are less loaded.
  • the screw plate be provided to receive the at least one secondary spring element.
  • this enables a stable, high-quality, compact and inexpensive design and connection of the handle device to the hand-held power tool.
  • Figure 1 shows a schematic view of a hammer drill and / or chisel hammer as an example of a handheld power tool 10 with a machine housing 20, a tool holder 54 movably arranged on the machine housing 20 for exchangeably receiving an insert tool 16 and with a drive device accommodated in the machine housing 20 and having a drive unit and a gear unit 14 for driving the insert tool 16 in different operating modes.
  • the tool holder 54 is preferably rotatably arranged on an end face of the machine housing 20.
  • the handle device comprises a switch actuator 24 for starting up the hammer drill and / or chisel hammer.
  • the switch actuator 24 can be switched both mono-stable and bi-stable between two switching positions.
  • an additional handle device 56 is arranged on the machine housing 20 of the hammer drill and / or chisel hammer, in particular is arranged to be adjustable.
  • Handheld power tool 10 has an operating mode switchover device 12.
  • an operating lever for an operating mode switchover is arranged on the machine housing 20, with which an operator can choose between different drive types for the insert tool 16 used in the tool holder 54.
  • the handle device for the handheld power tool 10 comprises a spring element 18 and a handle unit 22, which is attached to the machine housing 20 so that it can move at least to a limited extent, which is vibration-decoupled from the machine housing 20 via the spring element 18 and comprises the switch actuator 24 for starting up the drive device 14.
  • the handle unit 22 includes an anti-vibration handle 58.
  • the handheld power tool device also has a Control means 28 via which the switch actuator 24 interacts with the operating mode switchover device 12 in such a way that the switch actuator 24 cannot be switched bi-stably in certain operating modes.
  • the control means 28 is designed as a tension band 30.
  • the assembly shown is composed of the following functional units: an intermediate plate 26, the spring element 18 and a slide switch assembly.
  • the intermediate plate 26 is the central component of this assembly. Their construction enables a number of possibilities for the simple implementation of existing functions in the hand-held power tool 10 formed by the hammer when the anti-vibration handle 58 is used and a mechanical switch actuation with changeover.
  • One of the central tasks of the intermediate plate 26 is to accommodate and guide the spring element 18, as in FIGS Figures 3a and 3b shown.
  • the spring element 18 is clamped into the anti-vibration handle 58 by the intermediate plate 26 and fixed at the clamping point via 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 the rigidity, bending line and paths of the spring element 18.
  • the spring element 18 is designed as a leaf spring 32.
  • the 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 Figures 4a to 4c Possible variants and configurations of the secondary spring elements 34, 34 ', 34 "are shown Figures 4a to 4c Bags with support ribs 60 and a frame 62 additionally for introducing damping elements into the intermediate plate 26.
  • the secondary spring elements 34, 34 ', 34 " can preferably be made of foam, a cellular rubber, a foam rubber, another synthetic or natural foam, elastomer, TPE , Rubber, a gel or a similar elastic material
  • the degree of damping or suspension can additionally be adjusted via the volume of individual chambers, and the frame 62 prevents jamming with other surrounding components.
  • Suspension and damping are consequently adjusted to one another centrally via the accommodation of the spring element 18 and the secondary spring elements 34, 34 ', 34 "in the intermediate plate 26.
  • the result is the compact assembly which is provided for preassembly and which contains all the essential components for the operative connection of the decoupling united with each other.
  • the principle facilitates the coordination of the components for decoupling and, moreover, opens up the possibility of deriving a rigid handle of the handle unit 22 without switching over by simply omitting the assembly.
  • the special design of the intermediate plate 26 also enables improved guidance of the handheld power tool 10 and in particular an improved transmission of operating forces on the anti-vibration handle 58 to the machine housing 20 of the handheld power tool 10 Figure 5
  • support points and receptacles of the intermediate plate 26 are designed in the upper area of a handle housing 64 and at the connection to the drive device 14 comprising a motor assembly so that 58 operating forces can be transmitted unfiltered or unsprung to the handheld power tool 10 along the force flow from the anti-vibration handle. This results in good user guidance for the handheld power tool 10.
  • the intermediate plate 26 is provided in the machine housing 20 and receives the spring element 18 on one side. Finally, the slide valve assembly is accommodated in the intermediate plate 26.
  • the slide valve assembly consists according to the Figures 6a to 6c consisting of a slide switch 66, the tension band 30 and a compensation spring 68. In addition to the intermediate plate 26, it forms a further important unit especially for 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 in the intended installation position by means of a snap hook connection (not shown). It is also conceivable that the z-shaped, cranked slide switch 66 can be rotated into the intermediate plate 26 with a simple pivoting movement.
  • the aspect ratio The guide surfaces with each other ensure sufficient pre-centering during the entire pre-assembly. This prevents incorrect assembly.
  • the material and geometry are decisive for the design of the tension band 30.
  • plastic offers a wide range of variations to combine low friction values with good emergency running properties and low susceptibility to dust. Therefore, a plastic is essential for this application a very suitable material.
  • a band cross section of the tension band 30 must run very flat in height and therefore long in width.
  • a rectangular cross-section with an aspect ratio of 1:10 was combined with an essentially circular-like, in particular circular, central fiber (see Figures 7a to 7c ), but cross sections with rounded corners and / or different aspect ratios, in particular in the range between 1: 2 to 1:20, particularly preferably from 1: 5 to 1:15, can also be advantageous.
  • the variation of the surface proportions also helps between stiffness and flexibility.
  • the essentially circular-like, in particular circular, portion serves to fill the mold in the manufacturing process and at the same time advantageously increases the strength.
  • the installation situation in the slide switch 66 creates a buffer which can compensate for all blurring from the production and mechanical behavior of the tension band 30, which is made of plastic.
  • the tension band 30 must have a body for receiving the compensation spring 68 and must be securely received / guided in the slide switch 66 with the aid of two rotary receptacles.
  • the slide switch 66 supports the compensation spring 68 on the opposite side and determines the measure for the compensation over the installation length.
  • a labyrinth 70 is further provided over the intermediate plate 26, which reaches inwards to cover the machine housing 20 comprising a striking mechanism housing and a housing cover, the drive device 14 comprising a motor assembly and the anti-vibration handle 58 (see Figure 9 ).
  • the labyrinth 70 reaches into the surrounding parts at the transitions and provides effective dust protection and safe operation, especially when the switch actuator 24 formed by the hammer switch is switched over. Additional sealing elements are therefore not required.
  • Another aspect of the invention relates to the fact that in the case of larger and more powerful handheld power tools 10, e.g. in the case of heavy hammer drills and chisels, the above-described fixing 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 also be inserted between the machine housing 20 and the leaf spring 32 in order to support the spring force of the too soft leaf spring 32.
  • the secondary spring elements 34 are each formed by an elastomer spring element 36.
  • the leaf spring can only be functionally or applied with force by a clamping piece and the screw plate on the back. No holding or fixing functions or forces can be initiated on the side of the leaf spring facing the device side.
  • the invention thus represents an extension of that from the publication DE 10 2006 029 630 A1 known solution, in order to be able to implement the anti-vibration handle concept presented there also with larger and more powerful hand-held machine tools.
  • the anti-vibration handle 58 held by the operator contains the switch actuator 24 designed as an on-off switch and is closed off by screwing a grip shell of the anti-vibration handle 58 towards the rear.
  • the leaf spring 32 is clamped at the top between the anti-vibration handle 58 and two screw plates 48.
  • the two screw plates 48 are pushed onto the leaf spring 32 on both sides in the transverse direction.
  • the screw plates 48 thus enclose an upper clamping area 50 of the leaf spring 32 except for the contact zone to the anti-vibration handle 58 in all spatial directions. This ensures a permanent and stable enclosure of the leaf spring 32.
  • Screw domes 52 are located in the screw plates 48, which serve to screw the screw plates 48 and thus one of the leaf springs 32 to the anti-vibration handle 58.
  • the screw plates 48, the leaf spring 32, the anti-vibration handle 58 and a tensioned bellows 72 form a fastening system which is advantageously held together by positive and non-positive engagement.
  • the positive connection is formed by mutually supporting and penetrating holding domes and ribs, so that the positive connection has only a fixing function and the essential forces are absorbed by the positive connection of the components.
  • a major advantage of the screw plates 48 pushed on both sides is the creation of additional functional surfaces in front of an area and to the side of an area of the screw plates 48 of the leaf spring 32.
  • the screw plates 48 are designed such that they accommodate the additional secondary spring elements 34. In addition to spring mounts, the screw plates 48 also have additional functions. In order to prevent the anti-vibration handle 58 from being torn out and thus also to prevent the leaf spring 32 from being overloaded, the screw plates 48 have lateral contact 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 rear stop.
  • a further function of the screw plates 48 is the lateral guiding and the covering of the control means 28 formed by the tension band 30 compared to the secondary spring element 34 formed from an elastomer the switch actuator 24 formed on the on-off switch is blocked during chiseling so that the operator does not have to continuously press the switch actuator 24.
  • the drawstring 30 must be able to slide smoothly on the leaf spring 32 and must not be jammed or jammed.
  • the tension band 30 is chambered in a shaft of the screw plates 48.
  • the bellows 72 is also chambered by the screw plates 48 in the anti-vibration handle 58.
  • the screw plates 48 also form the end stop in the longitudinal and vertical directions of the anti-vibration handle 58.
  • the lower leaf spring clamp has advantageously been integrated into the screw connection system of the back plates 38 to the machine housing 20 (see Figures 14a and 14b ).
  • the formerly one-piece back plate was divided into two mirror-symmetrical back plates 38 in order to be able to fulfill all the required functions, inexpensive assembly and tool formability.
  • a spring plate 40 is inserted at the top with its two retaining ribs 42 into two corresponding holding grooves 44 of the rear plates 38 designed as housing rear plates and then folded back towards the rear plates 38 against a leaf spring tension ,
  • two snap hooks 46 are integrated in the rear plates 38, which snap into the spring plate 40 and hold it in the assembly position.
  • the complete preassembled handle device designed as a handle assembly can then be applied to the core device in an assembly line.
  • both non-positive and positive elements are used to clamp the leaf spring 32.
  • the leaf spring 32 has at its lower end two openings and a fold 74.
  • the leaf spring 32, the spring plate 40 and the machine housing 20 are on two domes on the respective side of the Back plates 38 threaded back plates formed.
  • the spring plate 40 also encompasses the two screw domes of the machine housing 20.
  • the fold 74 of the leaf spring 32 is clamped between the rear plates 38 and the spring plate 40.
  • the height of the spring plate 40 is designed in such a way that the leaf spring 32 is firmly clamped at the bottom over approximately 25% of its length. The remaining length can freely cantilever when compressed.
  • 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 however only acted upon after a certain spring deflection.
  • Figure 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, with which the leaf spring 32 is enclosed, are designed to the front in such a way that they still take up one or the additional secondary spring elements 34.
  • a foamed molded elastomer part is introduced between the screw plate 48 or the leaf spring 32 and the spring plate 40.
  • the elastomer molded part is designed as the elastomer spring element 36 and forms the secondary spring element 34.
  • Foamed elastomer molded parts have the advantage of cost-effective production through a continuous extrusion process with subsequent cutting to the required length. Furthermore, they work in almost all spatial directions, i.e. they have no preferred direction, e.g. a helical compression spring.
  • the advantageous secondary spring element 34 which is designed as an elastomer spring element 36, supports the leaf spring 32 under loads which lie above an optimal operating pressure point.
  • the optimal operating pressure point is the minimum pressure that just has to be provided by the operator so that the handheld power tool 10 formed by the hammer drill performs a regular and clean impact operation. This operating pressure is dependent on the performance class of the handheld power tool 10 and on the respective application.
  • an at least two-stage spring characteristic is generated. Up to the operating contact point, only the leaf spring 32 acts, so that very good decoupling of the anti-vibration handle 58 can be achieved with a low vibration level. A good decoupling is achieved in this area primarily because the leaf spring 32 has a very low damping constant. If the hand-held power tool 10 is overpressed or falls onto the anti-vibration handle 58, the elastomer spring element 36 then absorbs the essential part of the loads.
  • the spring stiffness of the leaf spring 32 be set such that the minimum operating pressure points for most important applications are achieved with a spring deflection between 2 mm and 10 mm, preferably between 3 mm and 7 mm, particularly preferably between 4 mm and 5 mm , From this pressure threshold, the secondary spring element 34 begins to act. The more the volume of the elastomer spring element 36 is deformed during the deflection, the stiffer the characteristic curve of the secondary spring element 34. It is therefore further proposed that volume compression of the elastomer spring element 36 be designed such that with an additional deflection of 2 mm to 5 mm, In particular from 3 mm to 4 mm beyond the minimum operating pressure point, the elastomer spring element 36 is compressed to 70% of its initial volume.
  • the elastomer spring element 36 is preferably made of foamed elastomer (foam rubber), which is produced in a continuous extrusion process with subsequent cutting to length.
