Description

The invention relates to a device connector receptacle of an electrical connection cable for a vacuum cleaner.

Such plug receptacles are known for electrical appliances. These form together with a plug in this plug a device-plug device that allows to solve an electrical device from its connecting cable. The plug receptacle is located on the connecting cable and the plug is firmly attached to the electrical appliance, so that the plug pins can not be live when unplugged. A device plug receptacle of the type in question for a vacuum cleaner is, for example, from the DE 196 08 245 A1 known.

The object of the invention is to develop such a connector receptacle in an advantageous manner.

To achieve the object, it is provided that the plug receptacle has a slot extending in the plugging direction, which separates the electrical area from a handle. According to this embodiment, a distinct, separate from the electrical area handle for plugging the plug receptacle is formed, which brings handling advantages with it. In addition, the extending between the electric area and the handle slot to guide the connector receptacle in the course of insertion serve the same. At the same time this situation orientation of the connector receptacle is given. Furthermore, it can be provided that in the inserted state of the electrical area and extending in extension of the same extension cable within an open, laterally arranged in the device handle groove are arranged almost in a hidden position and the separate handle protrudes laterally over the device handle. In addition, it is preferred that the electrical area of the plug receptacle has a rectangular cross-section. It is further provided that the handle projects beyond the electrical area of the plug receptacle in the longitudinal extension thereof. As handling-friendly also proves that the handle has a grip-friendly profiling and on the opposite side of the profiling an equally friendly, trough-like shape.

Furthermore, the invention relates to a device handle for a vacuum cleaner with a winding-Halterungsausformung for an electrical connection cable.

Device handles of the type in question are known in a variety of embodiments and are used to handle the vacuum cleaner as a hand-held device. It is also known to arrange on the device handle an electrical connection cable for powering the vacuum cleaner, this connection cable is space-saving wound on a correspondingly formed Halterungsausformung the device handle. In addition, solutions are known in which the electrical connection cable can be removed from the device handle, for direct placement of the same on the vacuum cleaner base unit.

With regard to the prior art described above, a technical problem of the invention is seen in designing a device handle of the type in question handling technology improved.

This problem is first and foremost solved by the subject matter of claim 4, wherein it is based on the fact that the device handle has over its length an insertion groove open to the outside, for receiving the connection cable. According to this embodiment of the invention is in the simplest way ensures a secure arrangement of the connection cable to the device handle. The connection cable is in this case in one, extending in the longitudinal extent of the device handle insertion groove, wherein preferably the depth of the insertion groove corresponds at least to the cable diameter, so that the latter does not protrude with its lateral surface over the contour of the device handle. The inventive solution also results in a simplified handling in Saugarbeiten without device handle, in which the connection cable is connected directly to the vacuum cleaner body. By receiving in the form of an insertion the connection cable is in the simplest way detachable from the device handle. In this case, it proves to be particularly advantageous if means are present in the insertion groove which hold the received connection cable, for example, in a latching manner. In this regard, an embodiment in which the insertion groove is partially closed by holding baffles is preferred. Such mounting baffles may be formed in the form of tongue-like extending over the groove opening device handle sections. According to this embodiment, the removal of the connection cable from the device handle only intentionally possible by the connection cable is pulled past the mounting baffles from the insertion. Furthermore, it is provided that the insertion groove opens to a narrow side of a device stem cross section. It also proves to be advantageous that two mounting baffles are arranged in the opposite direction projecting in the longitudinal direction of the insertion side by side, wherein between the mounting baffles an oriented on the diameter of the electric cable opening remains. Thus, the connection cable is inserted by looping the opposing projecting mounting baffles into the groove, after which the connection cable is secured by the mounting baffles against an automatic release of the device handle. The remaining between two opposing projecting mounting baffles opening is chosen so that a slight looping around the mounting baffles without kinking of the connecting cable can be achieved. If the insertion groove and the retaining baffles consist of a plastic material that protects the connection cable, the opening remaining between two retaining baffles can be equal to or slightly smaller than the cable diameter. The cross-section of the insertion groove, however, is preferably chosen to be larger than the cable diameter, so that in the course of the arrangement of the connection cable to the device handle the connection cable can be pulled through the insertion slot until the final positioning. Particularly advantageous is an embodiment in which the device remote end of the insertion a cable-friendly outlet opening is formed. Thus, it is provided that the insertion groove extends radially outward widening, whereby at the groove end a kink protection for the inserted connection cable is formed. In addition, it proves to be advantageous in terms of handling that the device handle has a grip area separate from the insertion slot.

The invention further relates to a device handle for a vacuum cleaner with a remote-acting power controller. Such a device handle is from the DE 196 08 247 A1 known. There, a device handle is shown and described, which controls the suction motor in the basic unit by electrical means. In order to develop a device handle of the type in question in an advantageous manner, it is proposed that the remote action is realized mechanically by means of a remote control rod having a Kupplungsausformung, for coupling to a motor unit of the vacuum cleaner. In accordance with the invention, the power position of the motor unit integrated in the vacuum cleaner base housing is thereby achieved in a mechanical manner, by connecting a remote control rod passing through the device handle to a power controller arranged on the handle side in the appliance handle. Due to the intended Kupplungsausformung the Fernwirkungsstange the device stem is removable together with the Fernwirkungsstange from the vacuum cleaner base unit, after which the vacuum cleaner, as known from the aforementioned patent application, can be used as over-floor device for sucking in difficult to reach areas. Due to the mechanically executed remote effect of the electrical connection of the vacuum cleaner can be provided directly to the vacuum cleaner base unit regardless of the mode, ie whether or not with device stem. In a development of the subject invention, it is provided that the remote control rod is designed as a rotary rod. This preferably rotates about the device stem longitudinal axis or about an axis parallel thereto. The acting on the remote control rod power controller may be designed as a turntable for this purpose. However, an embodiment is preferred in which the rotary rod is coupled to the power controller via a worm gear. According to this embodiment, the power controller can be designed in the form of a user-friendly sliding plate. The sliding actuation of the power controller, which preferably takes place in device longitudinal extension, is converted via the worm gear into a rotary movement of the remote operation rod. In this regard, a solution is preferred in which the worm gear is formed by a worm rib formed on the remote action rod which cooperates with an associated groove of the power actuator. The mentioned Kupplungsausformung is formed in a preferred embodiment of the subject invention by a tubular formation of the device-side end portion of the remote control rod. It is further provided that a remote action extension is provided on the device side, which couples with the remote control rod when inserting the device handle. Thus, a triggered via the power controller of the device handle rotational movement of the remote control rod is transmitted to the remote action extension of the basic unit, via which the latter is the control of the motor unit. Remote action extension and Telecontrol rod are preferably rotatably coupled to each other, being retracted in the coupling position of the remote action extension in the telemetry rod. In order to enable the usual telescoping of the device handle also in conjunction with a mechanical remote effect, is provided in an advantageous development that between the remote action extension and the remote action rod a rotary coupling is achieved by interlocking a rod-side rib and a side groove. The rod-side rib in this case has a length measured in the longitudinal extension of the device handle length, which corresponds at least to the maximum Teleskopiermaß, so that regardless of the device handle extract position of the drehkuppelnde engagement of the rod-side rib is given in the extension-side groove. In order to ensure a targeted retraction of the rib in the groove even when not aligned with each other alignment, it is proposed that upstream of the groove on the Fernwirkungsfortsatz a guide ramp is formed. The latter causes by loading by the rod-side rib -with angular offset assignment of rib and groove- an automatic Drehrück- or Drehvorverlagerung of the groove having Fernwirkungsfortsatzes to a position in which the rib and the groove are aligned. Thus, the desired coupling of Fernwirkungsfortsatz and Fernwirkungsstange is independent of the position of the device handle side power controller achievable. Preferred in this regard is an embodiment in which the guide ramp is designed as a central rib with lateral guide surfaces, wherein the guide surfaces screw into the groove over the length of the wall. The central rib serves as a deflector for the rod-side rib, so that the latter slides on the left or right side of the rib on the associated guide surface, resulting in a corresponding rotational displacement of the Fernwirkungsfortsatzes to the insertion of the rib in the groove. According to this embodiment, a dead zone is avoided. As a particularly advantageous prove the features described above in an embodiment in which the remote action extension is connected to a device-side power controller. Thus, a finding of remote action extension and remote action rod is independent of the positions of the two power controller, preferably the device handle side power controller has priority. This means that preferably the position of the device handle side power controller when inserting the device handle in the basic unit on the base unit side power controller is transmitted by rotational displacement of the remote action extension in the course of the clutch and the consequent action by the rod-side rib. The device-side power controller preferably acts on the motor unit via electronics. It is also proposed that the device-side power controller is designed as a turntable with an axis of rotation extending in the direction of the stem axis. It is also conceivable here, however, an embodiment according to the coupling between gerätestielseitigem power controller and remote control rod by means of a worm gear so that the device-side power controller can be designed as a sliding plate. In the device-side, preferably designed as a turntable power controller of the remote action extension is preferably angularly movable, but recorded longitudinally rigid. Thus, the, associated with the turntable end portion of the Fernwirkungsfortsatz two between a groove leaving longitudinal ridges, which engage in a corresponding groove or the like of the turntable, which allows an elastic relative movement in the direction of rotation by deformation of the longitudinal webs. Thus, in the simplest way tolerances in the rotational paths of the individual, coupling components can be accommodated.

The invention also relates to a power controller in a device handle of a vacuum cleaner, wherein the power controller is designed as a sliding plate and includes several levels of performance. In order to improve a power controller of the type in question in particular handling technology, it is proposed that the power controller comprises at least three power levels, with an end power level is adjustable only after overcoming a mechanical obstacle. The power controller can act on both the electrical and mechanical ways on the base unit side motor unit. According to the invention, the first and second power levels can be set without major obstacles at three power levels. A usual detent is also conceivable between these first stages. These two performance levels are usually sufficient for the usual suction work. However, if an increased suction power is required, then the end power level can be reached after overcoming a clear obstacle. This obstacle is more difficult to overcome than the detent positions between the usual power levels, so that the user must overcome this obstacle before the end performance level willful. In this regard, an embodiment is preferred in which the obstacle is an outwardly projecting rib which is to be pushed under a device-side boundary of the power controller clearance. This rib, which is also visible on the upper side of the power controller, is to be pressed down in order to obtain the end power level such that a further displacement of the power controller is made possible.

Shown and described is first with reference to FIG. 1, a vacuum cleaner 1 with a, not shown, a motor unit having basic unit G, to which a filter chamber 2 is connected. The basic unit G has a cantilever over the filter chamber 2 boom 3, at the free end of a plug-in receptacle 4 is formed. In this plug-in receptacle 4, a device stem St is inserted, wherein the insertion portion of the device stem St is formed as an aluminum profile section 5. By contrast, the adjoining handling section 6 is preferably produced by the plastic injection method.

The device handle St is telescopically displaceable in the usual way in the arm 3 of the basic unit G, wherein the desired extension position of the device handle St is latched. For this purpose, the device handle St evenly distributed in the longitudinal extension of the same arranged recessed recesses 7 for the entry of a provided in the region of the plug-in receptacle 4 of the boom 3 locking pin 8 (see Fig. 19). This spring-loaded in the latching direction latching pin 8 is zurückverlagerbar by means of a rocker-like handle 9 to release the device handle St.

The electrical connection is made via a connection cable 10, which at one end has a standard electrical connector and at the other end a device connector receptacle 11. As can be seen in particular from the illustrations in FIGS. 3 and 4, the device connector receptacle 11 has a in Plug-in direction r extending slot 12, which separates an electric area 13 of a handle 14. The electrical region 13 in this case has a substantially rectangular cross-section. The arranged in this electrical area 13 tab receptacles 15 which are electrically connected and rearwardly connected to the connecting cable 10, open into a recessed to the free end face 16 of the electric area 13 receiving floor 17th

Furthermore, the electric area 13 extends essentially in the axial extension of the connection cable 10.

The handle 14 of the device connector receptacle 11 extends substantially parallel to the electrical area 13, the slot 12 provided between the electric area 13 and the handle 14 opening in the plug-in direction r. Furthermore, the handle 14 is provided on the upper side with a profiling 18 for improved handling. On the underside, the handle 14 has a concave shape 19.

As can be seen in particular from the representations in FIGS. 6 and 7, the handle 14 projects beyond the electrical area 13 in the direction of insertion r.

In addition, the slot 12 facing inner edge of the handle 14 is provided with a rib 20 extending in the direction of insertion r.

The device connector receptacle 11 of the connection cable 10 is coupled for electrical contacting of the blower motor arranged in the basic unit G with a plug 22 in the receptacle 4 of the base device-side arm 3, flat plug 21 having device plug 22 coupled, said device plug 22 in the device Plug receptacle 11 dips and the tab 21 engage in the appropriately aligned tab receptacles 15 electrically conductive.

The device-side device connector 22 is associated with a plan view of the plug-in receptacle 4 as shown in FIG. 5 a lateral region. The formed between the electric area 13 and the handle 14 of the device connector receptacle 11 slot 12 takes in the coupled position to the device connector 22 adjacent wall portion of the boom 3, wherein by intervention of said handling-side rib 20 in a correspondingly shaped and positioned Wandungsnut 23 of the boom 3 is given a further guide the device connector receptacle 11 in the direction of insertion r.

As can be seen from the illustrations in FIGS. 6 and 7, the pluggability of the device connector receptacle 11 is independent of whether a device handle St is inserted for use of the vacuum cleaner 1 as a stick vacuum cleaner or whether this to use the vacuum cleaner 1 as an over-floor device is removed.

If the device handle St is plugged into the plug-in receptacle 4, then the appliance plug receptacle 11, in particular the electrical area 13 and the adjoining connecting cable 10, lie in an insertion groove 24 which opens outwards to a narrow side of the appliance stem cross-section and whose diameter and opening width adapted to the electrical range dimensions of the device connector receptacle 11. This insertion groove 24 extends over the entire length of the device stem St, wherein the groove cross section in the region of the handling section 6 is reduced. As a result, a relative displacement of plugged-device connector receptacle 11 and device stem St, in particular the aluminum profile section 5 is given in a telescopic longitudinal displacement of the device handle St.

The insertion groove 24 is partially closed in the region of the handling portion 6 by tongue-like protruding from the opposite longitudinal edges of the insertion groove 24 mounting baffles 25, wherein first two sides of the Einlegeutabschnittes in the handling section 6 two mounting baffles 25 are oppositely projecting in the longitudinal direction of the insertion groove 24 side by side. Between these pairs of mounting baffles 25 there remains one each on the diameter of the connecting cable 10 oriented, slit-shaped opening 26th

Due to the arrangement of these mounting baffles 25, the connecting cable 10 is caught in the insertion groove 24. However, removal of the connection cable 10 is made possible in a deliberate manner, overcoming the mounting baffles 25. Retrofitting of the connection cable 10 can be facilitated by an elastic configuration of the mounting baffles 25.

As shown in the drawings, 25 may be provided between the two end-side pairs of mounting baffles a further, central Halteschikane.

A lower broad side of the handling section 6 associated with Aufwickel Halterungsausformungen 27 are provided, around which the connection cable 10 can be wound to save space when not using the vacuum cleaner 1.

On the side facing away from Halterungsausformungen 27 broad side of the handling section 6 is a separate, but with the Handling section 6 of the same material connected, bow-shaped handle portion 28 formed.

The device-distal end of the insertion groove 24 merges into a cable-protecting, soft radially outwardly curved and partially in the handle portion 28 expiring outlet opening 29, whereby a device-side kink protection for the connecting cable 10 is provided.

The power control of the arranged in the base unit G motor unit is carried out when using the vacuum cleaner 1 as an over-floor device, d. H. In the illustrated embodiment, four power levels are adjustable, with an off-level with A, the two following power levels with L1 and L2 and a End power level is denoted by L3.

With this power controller 30 is a to the receptacle 4 extending through the boom 3 Fernwirkungsfortsatz 31 whose longitudinal axis extends in extension of the axis of rotation y of the power controller 30 and thus parallel to the Gerätestielachse x. This Fernwirkungsfortsatz 31 is longitudinally movably received rigidly on the power controller 30. However, there is a relative angular mobility to each other. This is achieved in that the Fernwirkungsfortsatz 31 consists of a plastic construction, wherein two between a groove 32 leaving longitudinal ridges 33 engage in a corresponding slot opening of the power controller 30 and thus allow an elastic deformation.

The Fernwirkungsfortsatz 31 serves the mechanical remote action of the motor unit by the arranged in the handle portion 28 of the device stem St further power controller 34 when using the vacuum cleaner 1 as a stick vacuum cleaner with a device handle St. This power controller 34 is designed as a sliding plate, by means of which the same power levels can be selected as with the device-side power controller 30.

The sliding power controller 34 acts on a telecontrol rod 35 accommodated in the equipment handle St. The latter is designed as a turning bar and held in a, the insertion slot 24 adjacent pipe section 36 of the device handle St. The arrangement is chosen so that the remote action rod 35 in the pipe section 36 is freely rotatable, but not displaced in the longitudinal direction.

The coupling between power controller 34 and remote action rod 35 via a worm gear 37, whereby the linear movement of the power controller 34 is converted into a rotational movement of the remote action rod 35. As can be seen in particular from the representation in FIG. 12 as well as from the schematic illustration in FIG. 21, the power controller 34 has a shoe 39 which can be displaced in a guide window 38 and which has a groove 40 in its end region facing away from the power controller 34 has. In this engages an end arranged on the remote control rod 35 screw rib 41 with its T-shaped profile (see Fig. Sectional view in Fig. 12). About this interaction of worm rib 41 and groove 40, the linear movement of the power controller 34 and its shoe 39 is converted into a rotational movement of the remote action rod 35.

The worm gear 37 remote from the end of the remote action rod 35 terminates at a distance from the associated free end of the device stem St, wherein the latter in this end portion has a radially outwardly widening plug opening 42.

The remote action rod 35 is further formed like a tube and has internally a radially inwardly extending rib 43. The length of this axially parallel extending rib 43 is adapted to the possible Teleskopierweg the device handle St.

In the course of insertion of the device stem St in the receptacle 4 of the basic unit G first causes the Einweiserfläche formed by the widening insertion opening 42 insertion of the free end of the base device remote action extension 31 through the insertion opening 42 and hereafter into the tubular remote control rod 35. Finally, a Rotary coupling between remote action extension 31 and remote action rod 35 achieved by the rod-side rib 43 engages in a radial groove 44 on the extension side (see Fig. 19). Thereafter, the converted by means of the worm gear 37 sliding movement of the handle side power actuator 34 is transmitted via the remote action extension to the device-side power controller 30 and via this optionally with the interposition of electronics to the motor unit. Here, the already described torsionally flexible coupling between remote action extension 31 and power controller 30 proves to be advantageous since this allows tolerances to be absorbed without destruction.

So that the remote action rod 35 and the remote action extension 31 can also be found independently of the respective position of the power controllers 30 and 34, a guide ramp 45 is formed on the remote action extension 31 in front of the groove 44. The latter is designed as a central rib 46, running perpendicular to the axis of rotation, with guide surfaces 47 on both sides, wherein the guide surfaces 47 to screw over the length of the wall in the groove 44. According to this embodiment causes at an unequal switch position of the two power controller 30 and 34, the impact of the guide rod-side rib 43 on one of the two guide surfaces 47 and thereafter further continued displacement of the device handle St in the insertion direction r Drehvor- or Drehrückverlagerung of the remote action extension 31 in the corresponding position of groove 44 and rib 43. Accordingly, the device-side power controller 30 always takes the position of the power controller 34 when inserting the device handle St.

As already mentioned, the vacuum cleaner 1 shown and described has three active power stages L1 to L3. According to the invention, it is provided that the end power stage L3 can be adjusted only after overcoming a mechanical obstacle, in particular at a setting via the power handle 34 on the device handle. For this purpose, this has a rib 49 projecting upwards in the direction of the actuating projection 48 of the power actuator 34 on reaching the power level L2 occurs against a boundary edge 50 of the power actuator Betätigungserviraumes 51. Upon conscious pressure actuation of the power controller 34, this obstacle is underrun by the rib 49, after which the desired end power level L3 is reached (see FIG. 22). The chosen obstacle can only be overcome by willpower.
