Intermediate plate 26 wanting in task to receive and at spring element 18, shown at Fig. 3 a and 3b.Spring element 18 all intermediate plate 26 is clamped to shockproof in handle 58 and all profiles and is fixed on clamped position method.At this, described profile is preferably realized in the abutment face of intermediate plate 26 methods, and spring element 18 can be supported on described abutment face method.The curve of described profile is determined rigidity, sweep and the displacement of spring element 18.Spring element 18 is configured to leaf spring 32.
In addition, intermediate plate 26 for receive one or more secondary spring elements or as one or more secondary spring elements 34,34 ', 34 " backstop, described secondary spring element can be used as damping element.At secondary spring element 34,34 ', 34 shown in Fig. 4 a to 4c " medium-sized scheme and the configuration imagined.At this, according to Fig. 4 a to 4c, there is the bag portion of brace rod 60 and framework 62 additionally for damping element is being entered to intermediate plate 26.At this, secondary spring element 34,34 ', 34 " preferably can be formed by foamed material, sponge rubber, foam rubber, other foamed artificial or natural foam, elastomer, TPE, rubber, gel or similar elastomeric material.At this, vibration damping or flexible degree can be additionally the volume-adjustment of single chamber all.Framework 62 prevents with other members around stuck all.
Therefore, elasticity and vibration damping are will be all by spring element 18 and secondary spring element 34,34 ', 34 " mutually regulate in being received in intermediate plate 26.The assembly of product method compactness, is arranged for pre-assembled and all important members that influence each other for de-coupling is integrated mutually at assembly.Be used in the coordination of parts of de-coupling to such an extent that simply and in addition open up following possibility in principle: under the situation expending in all not having, leave out assembly, at the handle that there is no to obtain under the situation of changing the rigidity of handle unit 22.
In addition, the special configuration of intermediate plate 26 can be realized better at hand held power machine 10 and especially the shockproof operating physical force in handle 58 methods is delivered to better to the machine case 20 of hand held power machine 10.For this reason, according to Fig. 5 in handle housing 64Fa district neck and with the junction at device 14 of driving of institute of institute motor component, the supporting location of intermediate plate 26 and acceptance division configuration like this makes along can or not being delivered to hand held power machine 10 methods from shockproof by operating physical force illogical filter ground in handle 58 line of force out vibration damping.Thus, draw good the operating in of hand held power machine 10.
Intermediate plate 26 is arranged in machine case 20 and at a side joint and receives spring element 18.Finally, in intermediate plate 26, receive conversion sliding assembly.At this, form by changing sliding component 66, drawstring 30 and counterbalance spring 68 according to Fig. 6 a to 6c at conversion sliding assembly.Switch-or when transition shift, described conversion sliding assembly also forms another important unit except intermediate plate 26 transmitting to switch executor 24 especially.Be configured to the device 28 of control of drawstring 30 by the one-tenth of plastics.
Thus, the size-dependent method of operation transition shift of switch executor 24 being worked can be only adjusting in a member.Need very little structure space.Install simple.Prevent at a bearing of widening of conversion sliding component 66 methods and in the step portion/level in device that in couples dust from entering into cunning between face.Principle method can be avoided the wrong function causing owing to being clamped in conversion sliding component 66 methods thus.
Can be all simple slippage fortune of the bending conversion sliding component 66 of z shape sliding in intermediate plate 26 and the grab Connection Card not all being shown specifically be locked in the installation site of setting.In addition,, in can imagining, the conversion sliding component 66 of z shape bending can all simply be put in fortune and rotate in intermediate plate 26.During whole pre-installation, be used to sufficiently feel relieved in advance at the length relation each other at face.Get rid of thus the danger of wrong assembling.
According to document 197 20 947A1, in order to change relatively hammer switch with operation type, displacement and power mechanically must be delivered to the converter method of the switch operator in handle by operating lever interference-free, state clearly the disclosure of document in usage at this.Under the combined situation of handle, opening up the solution that is similar to publication DE10 2,010 038 753A1 with shockproof, wherein, drawstring is arranged in handle fortune in the fiber of the centre of device.
But, the middle shape of friction loss, spring element 18 and the logical journey aspect of making make in the realization in practice of this programme difficultly.
For in reason, for the enforcement of drawstring 30, particular importance in material and physical dimension.As material, plastics provide very multiple middleization, so that by unified to low friction valve and good emergency operating characteristic and low dust sensitiveness.Therefore, plastic base this law is for material most suitable in application.
In order fully to realize the rigidity for transmitting pulling force, and do not lose simultaneously spring element 18 all take flexibility, conclusive in cross section relation.
The band cross section of drawstring 30 must extend longways very flatly aspect height and for this reason aspect width.This structure in, there is side ratio and select in combination (seeing Fig. 7 a to 7c) at rectangular cross section and median fiber Basic Law sub-circular, especially circular of 1:10, but in, have the angle of rounding and/or different side ratio cross section also can there is advantage, described side ratio especially at 1:1 to 1:20, particularly preferably in the scope between 1:5 to 1:15.
Face percentage can be middle in the scope of the middle length of drawstring 30 regulate, but in, neutralization must be kept in balance.Thus, although use ring and transfer, but tension force in maintaining not in in drawstring 30.Can guarantee the uniform load of material.
In the changing of face percentage, be also conducive to rigidity and elasticity.Basic Law sub-circular, especially circular part for the logical journey of making fill mould and advantageously improve intensity simultaneously.
Due to the remarkable stream of making in tolerance, thermoelasticity length plastics while changing, shake in/recrystallization with at drawstring 30 stand under load in characteristic, in the time transmitting by the pulling force of drawstring 30 methods of the one-tenth of plastics and displacement, poor addition, described difference can only be guaranteed the function reliably and in full of switch executor 24 conditionally with mechanical approach.
See that by means of counterbalance spring 68(Fig. 6 a) can solve described difficulty simply.
Aspect the pretension of counterbalance spring 68, in conversion, the state that packs in sliding component 66 is realized buffer all, described buffer can compensate the one-tenth of free plastics drawstring 30 make and all inaccuracy of mechanical property.
For this reason, drawstring 30 must have body for receiving counterbalance spring 68 and by means of two rotation acceptance divisions conversion sliding component 66 reliably received/to.Conversion sliding component 66 make counterbalance spring 68 be supported on opposite side method and all installation length determine compensation degree.
Now, in the time of manipulation transforms device, displacement is from conversion sliding component 66 and power is delivered to drawstring 30 relatively and switch executor 24(is shown in Fig. 8 a and 8b).In described coupling no longer rigidity and neutral line-flexible.It forms hammer switch conversion sliding component 66 and switch executor 24() displacement between the shifter lever of method so designs, make in counterbalance spring 68 in keep certain deposit.Be in operation and can be used in during tolerance balancing and compensation change by hot, the length flexible and plasticity of drawstring 30 methods of the one-tenth of plastics by the deposit of the length composition of counterbalance spring 68.Logical carry that protection is guaranteed and all counterbalance spring 68 now to determine that pulling force is applied to drawstring 30 methods by mode.
In order installing simply, one opening to be set in device above and to give drawstring 30 in conversion sliding component method and arrange one once being connected, in also and be connected and (see Fig. 8 c).Drawstring 30 is coordinated mutually with the acceptance division of changing in sliding component 66 aspect width.Thus, drawstring 30 can changed to the acceptance division in sliding component 66 in break-through simply together with counterbalance spring 68.In the power of drawing direction method arranging, member is then moved to it by leisure and is packed in position and remain fixed in wherein all.
In addition, prevent dust in order there to be method, at intermediate plate, 26 method sides arrange labyrinth-type excluder 70, and it extends inward the driving at device and shockproofly see Fig. 9 at handle 58(of machine case 20, institute of institute motor sub-assembly of institute's beater mechanism housing and case lid for hiding).Labyrinth-type excluder 70 has been responsible for method in place of the logical portion of crossing extend into parts around and when the switch executor 24 being made up of hammer switch in conversion especially and has been prevented dust and move reliably.Thus, do not need additional potted component.
Another aspect of the present invention relates to the following situation, in the hand held power machine 10 of more medium-sized and middle power, as in heavy hammer drill and cutter hammer, it is fixing no longer enough that leaf spring 32 is described at shockproof normal plane between handle 58 and machine case 20.Here, as no longer enough as unique spring element in leaf spring 32.Also must between machine case 20 and leaf spring 32, pack additional secondary spring element 34 into, to support the spring action of logical soft leaf spring 32.Secondary spring element 34 is made up of elastomeric spring element 36 respectively.
According to publication DE10 2,006 029 630A1, leaf spring all clamping element and spiral plate only loads at functional approach or with power at dorsal part.The side method towards utensil side at leaf spring can not enter maintenance or fixed function or power.Thus, in the present invention by the expansion of the disclosed solution of publication DE10 2,006 029 630A1, even if to also can realize the shockproof in handle scheme of suggestion there in the hand held power machine of more medium-sized and middle power.
Kept by operator shockproof 58 of handles the oco that is configured to close switch executor 24 and all the spiral of the shockproof handle shell at handle 58 connect to rear enclosed.
At normal plane, leaf spring 32 clamps between handle 58 and two spiral plates 48 shockproof.Two spiral plates 48 are pulled to leaf spring 32 methods in both sides in horizontal direction method.Thus, two spiral plates 48 towards shockproof at handle 58 the method pinch zones neck 50 at all direction in space methods institute coaming plate spring 32, except the district's neck that reclines.This guarantees lastingly and stably to surround leaf spring 32.In in spiral plate 48, at spiral cover 52, connect described spiral plate 48 and and then leaf spring 32 fixed at handle 58 with shockproof for spiral at spiral cover.Spiral plate 48, leaf spring 32, shockproofly form fixed system at handle 58 and clamped bellows 72, fixed system all sealed the and force closure of shape advantageously combine.Described shape sealed all each other supporting and the maintenance cover that penetrates and muscle form, thereby described force closure only has fixed function and the sealed reception of shape by member in the power of wanting.
Both sides by the obvious advantage of the spiral plate 48 of pushing manipulation in the spiral plate 48 Yi Ge districts necks of leaf spring 32 above and the side of Yi Ge district neck realize additional functional surfaces.
In the neck of forward region, spiral plate 48 is so constructed, and makes it can receive described additional secondary spring element 34.Except spring receives, spiral plate 48 also has additional function.For prevent shockproof handle 58 tear and and then also prevent that the logical of leaf spring 32 carry, spiral plate 48 has the abutment face of side direction, described abutment face is supported on two backboard 38 methods that are configured to housing backboard at dorsal part.Thus, shockproof have backstop stable and definite dorsal part at handle 58.In another function of spiral plate 48 with respect to the secondary spring element 34 being formed by elastomer laterally to the device 28 that hides the control that formed by drawstring 30.During cutter pricker, drawstring 30 blocks by oco and closes the switch executor 24 forming all, thus operator's push switch executor 24 constantly.Drawstring 30 must be reposefully leaf spring 32 method cunnings and do not allow be stuck or clamp.
In the time shifting together two spiral plates 48 onto leaf spring 32 method, drawstring 30 is by the well columnar structure of being trapped among spiral plate 48.Bellows 72 also all spiral plate 48 be trapped among shockproof in handle 58.In addition, spiral plate 48 also forms terminal backstop at the shockproof longitudinal direction at handle 58 and short transverse method.
Leaf spring clamping device below is advantageously integrated in the spiral connected system device of backboard 38 and machine case 20 (seeing Figure 14 a and 14b).The backboard of single type is divided into the backboard 38 of two mirror image symmetries before, to can meet desired all functions, good installability and the final molding of instrument.
As in publication DE10 2,006 029 630A1, when mounted, all two backboards 38 are pushed together, enclose being installed to the shockproof bellows 72 in handle 20 methods and dolly (not shown).Because needs make leaf spring 32 pretensions, leaf spring 32 is a little outstanding from the backboard 38 being made up of housing backboard.In order leaf spring 32 to be pressed in its run location simply when mounted, latch plate 40 keep with its two at normal plane muscle 42 be inserted into two corresponding maintenance grooves 44 of the backboard 38 that is configured to housing backboard in and then resist the direction method turning out backward of leaf spring tension force at backboard 38.In order to remain on position, integrated two grabs 46 in backboard 38, described grab snaps in latch plate 40 and by described latch plate and remains in installation site.Then, the complete door handle device that is configured to handle assembly of this pre-installation like this can be applied to core utensil method in hookup wire.
In order to clamp described leaf spring 32, use the sealed element of not only force closure but also shape.Sealed as shape, leaf spring 32 has two Chuan Kou and a zigzag part 74 in its bottom method.Leaf spring 32, latch plate 40 and machine case 20 are strung in two cover methods of the respective side of the backboard 38 being made up of machine case.In addition also two spiral covers of the machine case of holding 20 of latch plate 40.The zigzag part 74 of leaf spring 32 is clamped between backboard 38 and latch plate 40.The backboard 38 being all made up of housing backboard is connected with the spiral of machine case 20, and all parts are clamped each other.Member is favourable mutually nested all, forms lasting connection, being connected to shaking in load in also sustaining in the hand held power machine 10 being made up of at instrument impact type electricity.
Even in spiral connects because sedimentation or the logical journey that gets loose occur that under the situation of pretension loss, described connection is also maintained based on described shape is sealed.Latch plate 40 is such configuration aspect its height profile, and leaf spring 32 approximately 25% method in its length is clamped below regularly.Remaining length can freely be stretched out in the time of compression.
In another aspect of the present invention as the combination of leaf spring 32 and at least one other secondary spring element 34 of elementary spring element, but in, be just loaded after certain compression displacement at secondary spring element.
Figure 15 illustrates the shockproof cross section at handle 58Fa Bu district neck with leaf spring 32 and secondary spring element 34.Spiral plate 48(is described spiral plate institute coaming plate spring 32 all) structure like this forward, make described spiral plate can also receive described one or described additional secondary spring element 34.In the embodiment illustrating, as between spiral plate 48 or leaf spring 32 and latch plate 40, put into the profiled elastomer element of a foaming.Profiled elastomer element is configured to elastomeric spring element 36 and forms secondary spring element 34.
The profiled elastomer element of foaming has advantages of the logical journey of all continuous extruding injection making inexpensively, is and then cut to the structure length needing.In addition, the profiled elastomer element of described foaming can almost work in all direction in space methods, also just in they unlike there is preferred orientations as helical compression spring.
In load, in best operating pressure point during with method, the favourable secondary spring element 34 that is configured to elastomeric spring element 36 is supported leaf spring 32.Minimum pressure in best operating pressure point, implements impact rule method and good and moves thereby must just apply by operator the hand held power machine 10 that makes to be made up of hammer drill in minimum pressure.Depend on power grade and the corresponding situation that uses of hand held power machine 10 at operating pressure.
Also with regard to middle theory, definite gap of elastomeric spring element 36 is set between abutment face all, product method is the spring indicatrix of two-stage at least.Before operating pressure point, only leaf spring 32 works, and has low shaking in the shockproof extraordinary decoupling zero at handle 58 of level thereby can realize.Because leaf spring 32 has low-down damping constant, therefore in district neck, also realize good decoupling zero in especially.Then, under the situation in pressure is logical or hand held power machine 10 with shockproof in the time that handle 58 falls, what elastomeric spring element 36 received load is wanting part.
Suggestion, the spring rigidity of leaf spring 32 is so set, and makes all between 2 millimeters and 10 millimeters, preferably between 3 millimeters and 7 millimeters, particularly preferably the compression displacement between 4 millimeters and 5 millimeters just can be for the important application situation minimal time operating pressure point of middle majority.From described pressure threshold, secondary spring element 34 starts to work.Elastomeric spring element 36 in the volume in when compression shape more in, the indicatrix of secondary spring element 34 steeper.Therefore suggestion in addition, the such configuration of volume compression of elastomeric spring element 36, makes additionally to compress 2 millimeters to 5 millimeters at super logical minimum operating pressure point, especially 3 millimeters to 4 millimeters time, the initial volume of elastomeric spring element 36 70% compressed.In the time further compressing 1 millimeter to 2 millimeters, the almost whole volume of elastomeric spring element 36 is loaded, thereby spring rigid phase is in increasing rapidly.This has advantage, with shockproof in the time that handle 58 falls, very many energy can be received, thus the member stand under load that the formula that is knocked loads is very little.Described compression property is the moulding targetedly of elastomeric spring element 36 product method or support all also.Therefore, also can build blown tubular or other can produce to push logical journey the profile of method.At this, the one-tenth of the preferred elastomer (foam rubber) by foaming of elastomeric spring element 36, it,, with the one-tenth of the continuous logical journey of extruding injection, is then cut off.
