A kind of preferred design according to the present invention, vacuum cleaner also has plastics tongue, this plastics tongue especially with handle tube accommodation portion Construction integration, wherein the handle tube lever by this plastics tongue with as clamp lever effect can coordinate with the additional soil fertility of this plastics tongue and/or friction fit be positioned in handle tube accommodation portion with being connected.By this structure of the vacuum cleaner of motorized motions, now it is likely to: on the one hand by braking or lock device, introduce the clamping force lock handle pipe in handle tube by means of lever on the other hand so that insert at each or extract position and can both seamlessly keep handle tube.As lock device, consider lock device separately here, the clamping of handle tube should be independent of by leverage by lock device separately.This lever and plastics tongue combined effect, the latter can with handle tube accommodation portion's Construction integration or be such as fastened at least in handle tube accommodation portion.Described lever design becomes in this case, make a pressure, that is the power on the direction in handle tube accommodation portion can import in plastics tongue so that handle tube is entered in handle tube accommodation portion by the pressure clamp of introducing plastics tongue and is therefore locked in handle tube accommodation portion.
Lever includes having driving lever in one embodiment the head shaped prejudicially and driving lever can be made to engage with lock device.The head shaped prejudicially on lever can with lever Construction integration or power formula and/or form fit formula be connected with lever.Therefore, in the sense of the present invention, the head of this shaping includes the shape of single-piece, for instance by the single-piece shape that injection molding technology manufactures, and this manifold manufacture by engaging in succession with lever.On eccentric head, shape driving lever in an advantageous manner so that lock device separately can and lever and plastics tongue between clamping independently operate.Especially this driving lever constructs on eccentric head as the extension of finger-shaped, the extension making this finger-shaped by eccentric head can describe a big radius and on the one hand therefore, it is possible to obtain big motion, big torque can be transmitted on the other hand, in order to there is a torque being enough to operate lock device.Additionally, the extension of the finger-shaped on eccentric head constitutes driving lever, use this driving lever extremely accurate to engage with lock device, thus reduce again the tolerance in lock device and therefore, it is possible to realize the solution of low cost.
Lock device includes kayser slide plate, location-plate and at least one spring clip in another embodiment, wherein kayser slide plate can be made to engage with location-plate by driving lever and kayser slide plate braking spring clip.Lock device with independently acted on by the clamping action of lever and plastics tongue.Contrary lock device is as the independent unit effect for lock handle pipe.By using and the coefficient kayser slide plate of location-plate, it is possible to braking spring clip.By using the kayser slide plate preferably extended along handle tube in handle tube accommodation portion to be likely to: not only locking handle tube in the region of lever point by point, and with the region of lever in realize the independent clamping device of handle tube dividually along the clamping device of handle tube.Spring clip is connected with handle tube to transmit retentivity.Being connected with handle tube to transmit power by spring clip, possibility exist that, by the locking of spring clip or fixing, handle tube is secured or locked in another point.By double locking handle tube in handle tube accommodation portion, it is possible to realize handle tube and be seamlessly maintained in handle tube accommodation portion.Carry out the clamping of the pointwise of handle tube according to prior art, be achieved in the support of the pointwise of handle tube.Especially when decreased food is big, say, that when extracting handle tube farther out from handle tube accommodation portion, the power big when having the especially floor of big frictional resistance acts on the locking device of handle tube.For seamlessly lock handle pipe in handle tube accommodation portion in this case, it is necessary to set up high accuracy and small gap in handle tube accommodation portion.By the other locking additionally support handle pipe in handle tube accommodation portion to handle tube used according to the invention so that even if also being able to reliably and seamlessly operate vacuum cleaner when extreme use vacuum cleaner.
If spring clip is a part for handle tube stopper, then produce another embodiment.The degree that kayser slide plate can extend along handle tube and advantageously extend in handle tube accommodation portion is so that handle tube stopper keeps engaging with kayser slide plate in each possible position of handle tube.In one embodiment, handle tube stopper can be formed as plastic member and by injection moulding process manufacture.Then, handle tube stopper can be connected with handle tube with power cooperation and/or friction fit and/or form fit formula.In one embodiment, handle tube stopper has such a shape so that handle tube at least can move in subregion and exceedes handle tube stopper and be at least shape-ordinatedly connected with handle tube simultaneously.Handle tube stopper is installed in the end of handle tube, and this end is inserted in handle tube accommodation portion.Spring clip constitute handle tube stopper a part and such as can with handle tube stopper Construction integration.Spring clip upwardly extends and can make to engage with kayser slide plate in the side of the kayser slide plate extended along handle tube accommodation portion in this case.If kayser slide plate moves by driving lever, then kayser slide plate moving axially at handle tube, wherein kayser slide plate engages with location-plate.Location-plate determines kayser slide plate not only in axially-movable, and can be raised by location-plate equally.The rising of kayser slide plate causes, and spring clip is clamped between kayser slide plate and handle tube accommodation portion or is seamlessly locked.Therefore between kayser slide plate, spring clip and handle tube accommodation portion, cause the locking that power coordinates and friction fit connects, this locking brake handle pipe plug or be located.By the region of the inner end at handle tube, i.e. gapless locking in the region of handle tube stopper, additionally fixed handle pipe, it is possible to realize the gapless locking of handle tube.In contrast to the prior art, being clamped in the region of plastics tongue by lever on the one hand and clamp handle tube, lock handle tube on the other hand in the region of handle tube stopper, this is realized by user rotating lever uniquely.Therefore, after clamping and locking, handle tube is fixed on its position doubly.Therefore, handle tube motion in handle tube accommodation portion is prevented by a kind of dual support.
If handle tube accommodation portion includes recess and spring clip includes extension, wherein the extension of spring clip is visible in the region of recess under by card lock status, then realize another advantage.Spring clip moves along handle tube accommodation portion together with handle tube when extracting or insert handle tube.In case of locking, say, that when operating lever, spring clip raises by kayser slide plate and is fixed in its position between kayser slide plate and handle tube accommodation portion.If shaping now an extension on spring clip and simultaneously at one recess consistent with the Trajectory of spring clip of handle tube accommodation portion internal shaping, then this extension being visible in the region of this recess after being raised by kayser slide plate.Here the observability of the extension of spring clip or spring clip operator can be made to identify that whether lever deflects is sufficiently large, in order to realize the reliable locking of handle tube.Therefore user is existed to the control mode of a vision, thus make the operation of vacuum cleaner become easy.Recess shapes on the side that the side with lever in handle tube accommodation portion is corresponding and is advantageous for, therefore for operator when operating lever directly facing extension.
In another embodiment, kayser slide plate is extending in handle tube accommodation portion axially along handle tube, and axially can move back and forth by driving lever.If kayser slide plate moves axially by driving lever, then during the clamping of handle tube, between handle tube and kayser slide plate, produce a kind of relative motion.Lever rotation and by plastics tongue clamping lever pipe during clamping so that is handle tube can infinitely can be locked in handle tube accommodation portion in each possible position.By the clamping that the cooperation of the power of handle tube and/or friction fit connect, handle pipe is directly anchored in its position.This clamping of handle tube determines, handle tube directly and has also kept its position when clamping process starts.But lever rotates further, until it reaches a final turned position of lever.During whole rotation process, eccentric head and the driving lever being installed on the outer end of off-centre operation rotate further.Driving lever engages with kayser slide plate, thus makes kayser slide plate move during whole rotation process.Preferred dead man is arranged on the end that the axis about lever is opposed with lever.Therefore the motion of the balancing out motions kayser slide plate of lever.It is raised by the motion of kayser slide plate with either directly through the location-plate kayser slide plate engaged with kayser slide plate and brakes spring clip.Can working in coordination between kayser slide plate and location-plate according to desired load forces so that the different power on spring clip can be defined according to the length of the size of vacuum cleaner and weight and handle tube or the torque that applies on handle tube.Especially location-plate is extending axially along handle tube accommodation portion and preferred and handle tube accommodation portion Construction integration equally.
Location-plate can construct on bearing of trend axially as bumps.If location-plate constructs as bumps, then kayser slide plate can have recess, this recess and this projection combined effect.Position in the non-tensioning of lever, say, that in zero position, location-plate is positioned at the recess of kayser slide plate.If making lever rotation and making kayser slide plate move, then this recess is moved by described projection and location-plate, and not only moves axially, and raises by location-plate.Raise by kayser slide plate and be applied to the power on spring clip here less than the clamping force being applied to by lever on plastics tongue in axially-movable.Therefore the relative motion between the handle tube clamped and kayser slide plate is produced.Kayser slide plate moves in the axial direction during the whole angle of rotation of lever, and handle tube remains stationary as in its position.
Lever includes clamping curve controlled in another embodiment, and wherein, as long as especially more than one clamping point, lever just can shift from a clamped position to a zero position independently.If handle tube can regulate (insert or extract) in handle tube accommodation portion, then there is a zero position of lever.If the angle that lever rotation one can be prespecified and handle tube sandwich in handle tube accommodation portion, then arrive a clamped position.Lever has the stop dog position of a definition in zero position, wherein, lever is such as substantially perpendicular to handle tube accommodation portion's orientation in handle tube accommodation portion and abuts in handle tube accommodation portion, as long as and in the direction of the opening more than one clamping point just automatically spring into zero position.Therefore, clamping point is such a point by axial line distance, pressure spot, eccentric curve, angle of rotation and lever ratio definition, make it possible to realize independent the unclamping until zero position, frequent and clamped position the distance of clamping point is in this case so that is reliably prevented more firm clamping and especially inadvertently opens independently from clamped position.
In another design variant, the angle of rotation of lever includes one 20 to 60 °, it is preferable that the angle of 30 to 50 ° and more preferably include the angle of 35 ° to 45 °.By the angle of rotation less than 60 °, operator is made easily to operate lock handle pipe.If lever is positioned at the zero position of substantially vertical with surface, a handle tube accommodation portion position, then lever is that lock handle pipe such as only needs to rotate 45 °.In this orientation, a position optimized in human engineering for clamping and braking is existed for operator.If picking up lever in the zero position that substantially right angle represents between finger and thenar (muscle that thumb root palm is prominent), being then only thenar and be provided with clamping, the power by the arm on lever realizes optimizing that it is possible to imports.Especially for reaching clamped position, operator needs maximum power, and maximum power is by being readily incorporated in lever for operator's direct lever.In clamped position, lever and handle tube accommodation portion separate, and are thus also prevented from sandwiching the danger of the finger holding lever.
If lever include a lever segment flattened stretched out, substantially can describe as cylindrical shape, the axle accommodation portion with off-centre operation and the eccentric head shaped prejudicially, its axis accommodation portion includes clamping curve controlled device, then be capable of a kind of favourable extension of the present invention.By columnar axle accommodation portion, lever can an axle inner support.Based on columnar axle accommodation portion, lever includes off-centre operation, this off-centre operation when lever rotation with the plastics tongue combined effect in handle tube accommodation portion.By this off-centre operation, clamping force is introduced plastics tongue, for lock handle pipe.The head shaped prejudicially rotates also around the axle of support lever, but staggers setting with off-centre operation side so that the driving lever being installed on eccentric head can be engaged in the kayser slide plate that side, handle tube side is removably received by.
Advantageously clamping curve controlled device is directly and plastics tongue combined effect.The clamping Curve Design of off-centre operation becomes so that can be not more than the clamping force of 500 newton to handle tube transmission by the relatively short pivot region of the one of lever such as 40 °.
In another design variant, lever is in the position almost vertical with the axially extending direction of handle tube in its zero position.If the axially extending direction of handle tube is expressed as x-axis line, then an axis definition y-axis line that this x-axis line is directed sidewards and an axis being perpendicular to the direction that this x-axis line points to lever represent z-axis line.Therefore, clamping curve controlled device is applied on handle tube in a z-direction, and in this case, around the rotation of y-axis line, handle tube can move lever in x direction.
Advantageously lever is in the position almost vertical with the axially extending direction of handle tube in its zero position.Described zero position is denoted here as the lever position almost vertical with the axially extending direction of handle tube and is especially expressed as the position that the flat lever segment stretched out of lever substantially extends in z direction.
Plastics tongue and handle tube accommodation portion Construction integration in another embodiment, and cave on a large scale three sides.The Construction integration in plastics tongue and handle tube accommodation portion provides the advantage manufacturing plastics tongue at low cost.The large-scale depressed part such as forming the U-shape surrounding plastics tongue here enables to plastics tongue relative to the motion of handle tube accommodation portion.The motion of plastics tongue is in a z-direction, say, that points to towards handle tube or points to away from handle tube.
Plastics tongue includes reinforcement in the bonding pad to handle tube accommodation portion in another embodiment.By the structure of this definition of plastics tongue, plastics tongue supports the independent resilience of lever.Plastics tongue can in inner side in this case, say, that in the side facing handle tube, becomes rib-like or perforation configuration.In this case, this perforation or ribbing design according to the inner side of the profile of handle tube, and thus the lever face that is adjacent on plastics tongue is smooth in the axial direction.
It is further advantageous that, axle accommodation portion includes an axle and axle supported on both sides in support U-clamp, here U-clamp grasping member pipe accommodation portion on the side opposed with axle accommodation portion is supported so that clamping force can be introduced in handle tube accommodation portion in the clamped position as the lever of clamp lever.Support U-clamp and preferably use steel making.Support U-clamp in this case for power transmission and the stablizing of whole clamping region.Here support U-clamp makes it possible for the other component being substantially made of plastic and realizes being not more than the clamping force of 500 newton.Only axle and support U-clamp steel making, and handle tube accommodation portion and lever, handle tube stopper and kayser slide plate can be made of plastic.The excellent aluminium of handle tube and more preferably with aluminum continuous casting section bar manufacture.
