Definitions

  • the invention relates to a handle device for a hand-held power tool.
  • Anti-vibration handles with an elastic connection to the hammer also cause relative movements between the hammer and the handle itself as a side effect due to the required rigidity.
  • EP1303383B1 discloses a handle device according to the preamble of claim 1.
  • 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 that is attached to a machine housing so that it can move at least to a limited extent and which has at least one spring element relative to the Machine housing is at least partially vibration-decoupled and includes a switch actuator to start up the drive device, wherein the switch actuator can be switched both mono-stable and bi-stable between two switching positions.
  • the handle device has an intermediate plate which is provided in the machine housing and which accommodates at least the spring element on one side, and a control means via which the switch actuator interacts with the operating mode switching device in such a way that in certain operating modes the switch actuator is not switched bistable can be.
  • “mono-stable” is to be understood in particular as meaning that the switch actuator has only one stable switch position into which the switch actuator can be switched or into which the switch actuator preferably automatically falls back, while the switch actuator is in at least one other switch position of a operator must be kept in particular.
  • “bi-stable” is to be understood in particular as meaning that the switch actuator has two stable switch positions into which the switch actuator can be switched.
  • the switch actuator is preferably in the form of an on/off switch for the hand-held power tool.
  • the handle device according to the invention with the features of independent claim 1 solves the task in a way that is easy to assemble and inexpensive. It fulfills all the requirements placed on it.
  • control means be designed as a drawstring.
  • the drawstring is made of a plastic.
  • the drawstring preferably has an at least essentially rectangular cross-section with an at least essentially circular, in particular circular, central fiber. It is also conceivable that the central fibres, at least essentially, have a quadrilateral or hexagonal cross-section or another cross-section that a person skilled in the art deems appropriate.
  • the central fiber is preferably intended to serve at least partially as a filling channel, in particular in an injection molding process, and/or to form an advantageously narrow contact line with the leaf spring. As a result, an advantageously cost-effective configuration can be achieved.
  • the at least one spring element is formed by a leaf spring. In this way, in particular, a preferably cost-effective 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 effect and the handle device can be used in particular in larger and more powerful hand-held power tools.
  • the secondary spring element is loaded only after a certain compression travel. It is preferably proposed that the spring stiffness of the spring element formed by the leaf spring is adjusted in such a way that with a spring deflection of between 2 mm and 10 mm, preferably between 3 mm and 7 mm, particularly preferably between 4 mm and 5 mm, there are 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 volume of the elastomer spring element is deformed during deflection, the stiffer a characteristic curve of the secondary spring element becomes.
  • a volume compression of the elastomer spring element is designed in such a way that with an additional compression of 2 mm to 5 mm, in particular of 3 mm to 4 mm beyond a minimum operating pressure point, the elastomer spring element is compressed to 70% of its initial volume. With further deflection of 1 mm to 2 mm, virtually the entire volume of the elastomer spring element is acted upon, so that the spring stiffness increases relatively quickly. This has the advantage that if the anti-vibration handle falls, a great deal of energy can be absorbed, so that the components that are impacted are less stressed.
  • FIG figure 1 shows a schematic view of a rotary and/or chipping hammer as an example of a hand-held power tool 10 with a machine housing 20, a tool holder 54 which is movably arranged on the machine housing 20 for exchangeably receiving an insert tool 16 and with a drive device which is accommodated in the machine housing 20 and has a drive unit and a gear unit 14 for driving the application tool 16 in different operating modes.
  • the tool holder 54 is preferably rotatably arranged on an end face of the machine housing 20 .
  • a handle device is also provided.
  • the handle device comprises a switch actuator 24 for starting up the rotary and/or chipping hammer.
  • the switch actuator 24 can be switched both monostable and bi-stable between two switching positions.
  • an auxiliary handle device 56 is arranged on the machine housing 20 of the rotary and/or chipping hammer, in particular arranged adjustably.
  • the hand-held power tool 10 has an operating mode switching device 12 .
  • an operating lever for mode switching is arranged on the machine housing 20, with which an operator can choose between different drive types for the insertion tool 16 inserted in the tool holder 54 .
  • the handle device for handheld power tool 10 comprises a spring element 18 and a handle unit 22, which is attached to machine housing 20 so that it can move at least to a limited extent, which is vibration-decoupled from machine housing 20 via spring element 18 and comprises switch actuator 24 for starting drive device 14.
  • the handle unit 22 includes an anti-vibration handle 58.
  • the hand-held power tool device also has a control means 28 via which the switch actuator 24 interacts with the operating mode switching device 12 in such a way that the switch actuator 24 cannot be switched bistable in certain operating modes.
  • the control means 28 is designed as a drawstring 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 structure allows a number of options for the simple implementation of existing functions in the handheld power tool 10 formed by the hammer when using the anti-vibration handle 58 and a mechanical switch actuation with switching.
  • One of the central tasks of the intermediate plate 26 is to accommodate and guide the spring element 18, as shown in FIGS Figures 3a and 3b shown.
  • the spring element 18 is clamped in 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 path of the spring element 18.
  • the spring element 18 is designed as a leaf spring 32.
  • the intermediate plate 26 serves to accommodate or as a stop for one or more secondary spring elements 34, 34', 34", which can serve as damping elements Figures 4a to 4c conceivable variants and configurations of the secondary spring elements 34, 34', 34" are shown Figures 4a to 4c Pockets with support ribs 60 and a frame 62 for the introduction of damping elements in the intermediate plate 26.
  • the secondary spring elements 34, 34', 34" can preferably be made of foam, cellular rubber, foam rubber, another synthetic or natural foam, elastomer, TPE , rubber, one Gel or a similar elastic material may be formed. The degree of damping or springing can also be adjusted via the volume of individual chambers.
  • the frame 62 prevents jamming with other surrounding components.
  • the special configuration of the intermediate plate 26 also enables improved guidance of the handheld power tool 10 and in particular improved transmission of operating forces on the anti-vibration handle 58 to the machine housing 20 of the handheld power tool 10.
  • 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, which includes a motor assembly, in such a way that operating forces can be transmitted unfiltered or unsprung to the hand-held power tool 10 along the flow of force from the anti-vibration handle 58. This results in good operator guidance for the handheld power tool 10.
  • the intermediate plate 26 is provided in the machine housing 20 and accommodates the spring element 18 on one side. Finally, the slide switch assembly is accommodated in the intermediate plate 26.
  • the slide switch assembly consists in accordance with the Figures 6a to 6c consists of a slide switch 66, the tie rod 30 and a compensation spring 68. In addition to the intermediate plate 26, it 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 tie rod 30 is made of plastic.
  • the z-shaped, cranked switch slide 66 can be pushed into the intermediate plate 26 with a simple sliding movement and latches in the intended installation position via a snap hook connection (not shown in detail). 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 length ratio of the guide surfaces to each other ensures sufficient pre-centering during the entire pre-assembly. This rules out incorrect assembly.
  • the material and geometry are particularly decisive for the design of the tie rod 30 .
  • plastic offers a wide range of variations in order to combine low coefficients of friction with good emergency running properties and low susceptibility to dust. 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 width.
  • a rectangular cross-section with an aspect ratio of 1:10 was combined with a substantially circular, in particular circular, central fibers are chosen (see Figures 7a to 7c ), but cross-sections with rounded corners and/or different aspect ratios, in particular in the range from 1:2 to 1:20, particularly preferably from 1:5 to 1:15, can also be advantageous.
  • Varying the surface area also helps between rigidity and flexibility.
  • the substantially circular, in particular circular portion is used to fill the mold in the manufacturing process and at the same time advantageously increases the strength.
  • the drawstring 30 must have a body to accommodate the compensation spring 68 and must be securely accommodated/guided in the switch slide 66 with the aid of two rotary receptacles.
  • the slide switch 66 supports the compensation spring 68 on the opposite side and determines the degree of compensation via the installation length.
  • a labyrinth 70 is also provided via the intermediate plate 26, which reaches inwards to cover the machine housing 20, which includes an impact mechanism housing and a housing cover, the drive device 14, which includes a motor assembly, and the anti-vibration handle 58 (see Fig figure 9 ).
  • the labyrinth 70 reaches into the surrounding parts at the transitions and, especially when switching over the switch actuator 24 formed by the hammer switch, effectively protects against dust and ensures safe operation. Additional sealing elements are therefore not required.
  • a further aspect of the disclosure relates to the fact that the above-described fixing of the leaf spring 32 between the anti-vibration handle 58 and the machine housing 20 is no longer sufficient for larger and more powerful handheld power tools 10, such as for example heavy drill and chisel hammers.
  • 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 keep the leaf spring 32 too soft in its position to support spring action.
  • the secondary spring elements 34 are each formed by an elastomer spring element 36 .
  • the leaf spring can only be loaded functionally or with forces on the back by means of a clamping piece and the screw plate. No holding or fixing functions or forces can be introduced on the side of the leaf spring facing the device side.
  • the disclosure thus constitutes an extension of that from the document DE 10 2006 029 630 A1 well-known solution to be able to implement the anti-vibration handle concept presented there in larger and more powerful handheld power tools.
  • the anti-vibration handle 58 held by the operator includes the switch actuator 24 designed as an on/off switch and is closed by screwing a grip shell of the anti-vibration handle 58 towards the rear.
  • the leaf spring 32 is clamped between the anti-vibration handle 58 and two screw plates 48 at the top.
  • 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 in all spatial directions except for the contact zone for the anti-vibration handle 58 . This ensures a permanent and stable enclosing of the leaf spring 32 .
  • Screw bosses 52 are located in the screw plates 48 and are used 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 braced bellows 72 form a fastening system which is advantageously held together by positive and non-positive locking.
  • the form fit is formed by holding domes and ribs that support and penetrate one another, so that the force fit only has a fixing function and the main forces are absorbed by the form fit of the components.
  • a significant advantage of the screw plates 48 pushed on on both sides is the creation of additional functional surfaces in front of an area and on the side of an area of the screw plates 48 of the leaf spring 32.
  • the screw plates 48 are designed in such a way that they can accommodate the additional secondary spring elements 34 .
  • the screw plates 48 additional functions.
  • the screw plates 48 In order to prevent the anti-vibration handle 58 from being torn out and thus also an overloading of the leaf spring 32, the screw plates 48 have lateral contact surfaces which are supported on the rear 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.
  • Another function of the screw plates 48 is the lateral guidance and covering of the control means 28 formed by the tie rod 30 in relation to the secondary spring element 34 made of an elastomer , so that the operator does not have to constantly press the switch actuator 24.
  • the drawstring 30 must be able to slide easily on the leaf spring 32 and must not be jammed or pinched.
  • the drawstring 30 is chambered in a shaft of the screw plates 48.
  • the bellows 72 is also chambered in the anti-vibration handle 58 by the screw plates 48 .
  • the screw plates 48 also form the end stop in the longitudinal and vertical direction of the anti-vibration handle 58.
  • the lower leaf spring clamp has been advantageously integrated into the system of screwing the back plates 38 to the machine housing 20 (see Figures 14a and 14b ).
  • the previously one-piece back plate was divided into two mirror-symmetrical back plates 38 in order to be able to fulfill all the required functions, favorable assembly and tool end formability.
  • the bellows 72 and rocker arms (not shown) already mounted on the anti-vibration handle 20 are chambered during assembly by pushing the two back plates 38 together. Due to the required prestressing of the leaf spring 32, the leaf spring 32 then protrudes a little from the back plates 38 designed as housing back plates. In order to be able to simply press the leaf spring 32 into its operating position during assembly, a spring plate 40 is inserted at the top with its two retaining ribs 42 into two corresponding retaining grooves 44 of the rear plates 38 designed as housing rear plates and then folded backwards against a leaf spring tension in the direction of the rear plates 38 .
  • two snap hooks 46 are integrated in the back plates 38, which snap into the spring plate 40 and this in the hold assembly position.
  • the complete handle device, designed as a handle assembly, preassembled in this way 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 two openings and a fold 74 at its lower end as a positive fit.
  • 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 38 formed by the housing back plates.
  • the spring plate 40 also encompasses the two screw domes of the machine housing 20.
  • the fold 74 of the leaf spring 32 is braced between the back plates 38 and the spring plate 40.
  • the height contour of the spring plate 40 is such that the leaf spring 32 is clamped firmly at the bottom over approximately 25% of its length. The remaining length can freely protrude during compression.
  • a further 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, however, is only acted upon after a certain compression travel.
  • figure 15 shows a cross section through the upper area 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 at the front in such a way that they can still accommodate one or the additional secondary spring elements 34.
  • a foamed elastomer molding 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 moldings have the advantage of being inexpensive to manufacture using a continuous extrusion process with subsequent cutting to the required length. Furthermore, they act in almost all spatial directions, i.e. they do not have a preferred direction like e.g. a helical compression spring.
  • the advantageous secondary spring element 34 designed as an elastomer spring element 36, supports the leaf spring 32 under loads that are above an optimum operating pressure point.
  • the optimum operating pressure point is the minimum pressure that the operator just needs to apply so that the hand-held power tool 10 formed by the hammer drill carries out a regular and clean percussion operation. This operating pressure depends on the performance class of the hand-held power tool 10 and the respective application.
  • an at least two-stage spring characteristic is generated. Up to the operating pressure point, only the leaf spring 32 acts, so that a very good decoupling of the anti-vibration handle 58 can be achieved with a low level of vibration. Good decoupling is also achieved in this area primarily because the leaf spring 32 has a very low damping constant. In the event of excessive pressure or if the hand-held power tool 10 falls onto the anti-vibration handle 58, the elastomer spring element 36 then absorbs the majority of the loads.
  • the spring stiffness of the leaf spring 32 is adjusted so that the minimum operating contact pressure points for most important applications are achieved with a compression travel of 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 deflection, the stiffer the characteristic curve of the secondary spring element 34.
  • a volume compression of the elastomer spring element 36 be designed in such a way 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. With further deflection of 1 mm to 2 mm, virtually the entire volume of the elastomer spring element 36 is acted upon, so that the spring stiffness increases relatively quickly increases. This has the advantage that if the anti-vibration handle 58 falls, a great deal of energy can be absorbed, so that the components that are impacted are less stressed.
  • a deflection characteristic described can also be brought about or supported by a targeted shaping of the elastomer spring element 36 .
  • Tubular or other contours that can be produced in a strand process can also be installed.
  • 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.
