Description

Handles, power controls and appliance sockets for vacuum cleaners

technical field

The invention firstly relates to a handle bar for a vacuum cleaner with a wrap-around profile for an electrical connection cable.

Background technique

Handles of this type are known in a wide variety of embodiments and are used to operate vacuum cleaners as hand tools. It is also known that an electrical connection cable for supplying electrical energy to the vacuum cleaner is arranged on the handle bar, for which connection cable there is a fixed molding that can be wound around a suitably formed handle bar in a space-saving manner. department. Also known are solutions in which the electrical connection cable can be detached from the handle bar in order to be placed directly on the base suction device.

Contents of the invention

The technical problem underlying the present invention is to design a handle bar of the stated type in order to improve the grip with respect to the prior art described above.

This problem is first and foremost solved by the subject-matter of claim 1 based on the fact that the handle bar has, over its length, an insertion slot open in the outward direction, which slot is intended to receive the connecting cable . This structure according to the present invention can easily ensure that the connecting cable is securely arranged on the handle bar. Here, the connection cable is arranged in an insertion groove extending longitudinally along the handle bar, the depth of which preferably corresponds at least to the diameter of the cable, so that the cable does not protrude beyond the contour of the handle bar with its lateral surface .

The solution according to the invention also leads to simplified handling of the vacuuming operation without a handle bar, in which case the connecting cable is connected directly to the vacuum cleaner base. As a result of the mounting structure in the form of an insertion slot, the connecting cable can be detached from the handle bar extremely easily. It has proven to be particularly advantageous if the insertion slot has means for securing the received connecting cable, for example with latching means. In this regard, a preferred structure is a structure in which the insertion groove is partially closed by the fastening bent portion. Such a fastening bend can be provided in the form of an integral part of the handle rod, which extends in a tongue-like manner over the opening of the slot. As a result of this construction, the connecting cable can only be detached intentionally from the handle bar by pulling it out of the insertion slot through the fastening bend. In addition, it is recommended that the insertion groove is open in the direction of the narrow side of the cross-section of the handle rod. It has also proved to be advantageous if the two fastening bends are arranged one next to the other in the longitudinal direction of the insertion slot, so that they protrude in opposite directions, an opening corresponding to the cable diameter remains in the fastening bend between sections. Therefore, the connection cable is inserted into the groove and clamped by the fastening bent portion protruding in the opposite direction, so that the connecting cable is clamped by the fastening bent portion to prevent automatic falling off from the handle bar. Here the opening held between the two fastening bends protruding in opposite directions is chosen such that the connecting cables can be easily snapped off by the fastening bends without tangling. If the insertion slot and the fastening bends are made of a plastic material that protects the connecting cable, the opening remaining between the two fastening bends can be equal to or slightly smaller than the diameter of the cable. In contrast, the cross-section of the insertion groove is preferably selected to be greater than the diameter of the cable, so that during the operation of placing the cable on the handle rod, the connecting cable can also be pulled through the insertion groove until it is finally positioned . A particularly advantageous configuration has proven to be the one in which a cable protection outlet opening is formed at the end of the insertion groove facing away from the device. The insertion slot is thus rounded in such a way that it widens radially outwards, so that a snag preventer for the inserted connecting cable is formed at the end of the slot. Furthermore, it is advantageous from an operational point of view if the handle lever has a grip area separate from the insertion slot.

The invention also relates to a handle bar for a vacuum cleaner having a remotely operated power control. Such a handle bar is known from DE 196 08 247 A1. This document shows and describes a handle lever that electrically controls the suction motor in the basic device. In order to advantageously develop a handle lever of said type, it is proposed that said remote operation is realized mechanically by means of a remote operating lever having a coupling structure for coupling to a motor unit of a vacuum cleaner. According to the invention, the power control of the motor unit integrated on the base housing of the vacuum cleaner is thus mechanically realized in that the remote operating lever passing through the handle bar is connected to the power on the grip part provided in the handle bar. controller. The conceived coupling of the remote operating lever allows the handle lever together with the remote operating lever to be removed from the basic vacuum cleaner, whereby the vacuum cleaner can be used as an above-floor device as known from the above patent application, For vacuuming in hard-to-reach places. Thanks to the remote operation of the mechanical structure, the electrical connection of the vacuum cleaner can be provided directly on the basic vacuum cleaner device, regardless of the mode of operation, ie whether it is operated via a handle bar. In a development of the subject matter of the invention, it is proposed that the remote operating lever is formed as a rotary lever. This operating lever preferably rotates about the longitudinal axis of the handle lever or about an axis extending parallel thereto. For this purpose, the power control acting on the remote joystick can be formed as a rotary control. However, a preferred construction is one in which the rotating rod is coupled to the power controller via a worm gear mechanism. As a result of this configuration, the power controller can be provided as a user friendly slide controller. The sliding actuation of the power control, preferably occurring in the direction of the longitudinal extension of the handle rod, is converted into a rotational movement of the remote operating rod via a worm gear mechanism. A preferred solution in this regard is one wherein said worm gear mechanism is formed by a helical rib formed on the remote control lever and interacting with an associated slot of the power controller. In a preferred configuration of the subject matter of the invention, the coupling structure is formed by the tubular structure of the device-side end region of the remote control lever. It is further proposed to provide a remote operation extension to be provided on the device, this extension being coupled with the remote operation rod when the handle rod is inserted. The rotation of the remote operating lever, induced via the power controller of the handle lever, is thus transmitted to the remote operating extension of the base unit, via which the motor unit is controlled. When the remote operation extension has been retracted into the remote operation lever in the coupled position, the remote operation extension and remote operation lever are preferably coupled to each other in a rotationally fixed manner. In order to also allow the usual retraction capability of the handle rod to be combined with mechanical remote operation, in an advantageous form of development it is proposed that the remote control extension and the remote control rod be realized by mutual engagement of ribs of the remote control rod and slots of the extension. rotating connection between. The length of the rib of the remote operating lever, measured here in the direction of the longitudinal extension of the handle rod, corresponds at least to the maximum telescoping distance, so that the rib of the remote operating lever engages in a rotationally coupled manner in the extension, regardless of the extended position of the handle rod. in the slot. In order to ensure accurate retraction of the rib into the groove even if the rib and groove are not aligned, it is proposed that a guide ramp be formed on the remote operation extension, in front of the groove. Through the action of the ribs of the remote lever - where the ribs and slots are offset from each other at an angle - the guide ramps cause automatic backward or forward rotation of the remote operating extension containing the slots into the ribs and slots relative to each other The aligned position. The intended coupling of the remote operation extension and the remote operation lever is thereby achieved regardless of the position of the power control located on the handle. A preferred configuration in this respect is one in which the guide ramp is designed as a central rib with lateral guide surfaces which transform into grooves over the length of the wall. Here the central rib acts as a deflector for the rib of the remote operating lever, so that the latter slides over the relevant guide surface to the left or right of the rib, which causes a corresponding rotation of the remote operating extension until the rib is introduced into the slot. This configuration avoids dead zones. The above features prove to be particularly advantageous in the configuration of the power controller in which the remote operation extension is connected to the device. The remote operation extension and the remote operation lever are aligned with each other regardless of the position of the two power controls, the power control on the handle preferably having priority. This means that when the handle bar is inserted into the base unit, the position of the power controller on the handle bar is preferably transferred to the base unit by the rotation of the remote operation extension and the concomitant action of the ribs of the remote operation lever during coupling on the power controller. A power controller on the device acts on the motor unit preferably via the electronics. It is also proposed that the power controller on the device is formed as a rotary controller whose rotation axis extends along the axis of the handle rod. However, it is also conceivable here to have a structure corresponding to the power control on the handle bar and the remote operating lever coupled by a worm gear mechanism, so that the power control on the device can also be formed as a slide control. The remote operation extension is preferably adapted for angular rather than longitudinal movement in the power controller, preferably formed as a rotary controller. The end of the remote operation extension associated with the rotary control has two longitudinal rails with a slot between them and engages in a corresponding slot or similar structure of the rotary control, which allows the deformation of the longitudinal rail by Elastic relative motion in the direction of rotation is produced. It is therefore very easy to accommodate tolerances in the rotational path of the individual coupling elements.

The invention also relates to a power control on the handle bar of the vacuum cleaner, which power control is formed as a slide control and has a plurality of power levels. In order to improve a power controller of said type, especially from an operational point of view, it is proposed that said power controller comprises at least three power levels, the final power level being able to be set only after mechanical obstacles have been overcome. The power controller can here act both electrically and mechanically on the motor unit in the basic device. In the case of three power levels, according to the invention, the first and second power levels can be set without major hindrance. It is also conceivable to provide specific locking means between these initial levels. These two power levels are usually sufficient for normal vacuuming. However, if increased pumping power is required, the final power level can be reached once a significant hurdle has been overcome. This obstacle is more difficult to overcome than the locked position between normal power levels, so that this obstacle before the final power level needs to be deliberately overcome by the user. A preferred construction in this regard is one in which the barrier is an outwardly projecting rib which is to be depressed below the device side edge of the power controller gap. In order to achieve the final power level, this rib, which is preferably visible on the upper side of the power controller, must be depressed in such a way as to allow further movement of the power controller.

Finally, the invention relates to a device socket for an electrical connection cable of a vacuum cleaner having a handle bar and a device part. Such sockets are known for electrical appliances. Each of these sockets together with a plug which can be inserted therein form an electrical device insertion means which allows the electrical device to be detached from its connection leads. In this case, the socket is arranged on the connecting lead, and the plug is firmly arranged on the appliance such that the plug pin is not under voltage in the unplugged state. A device socket of the type described for a vacuum cleaner is known, for example, from DE 196 08 247 A1. In order to advantageously develop a socket here, in particular from an operational point of view, it is proposed that the socket has a groove which extends in the direction of insertion and separates the electrical area from the handle. This configuration forms a defined handle, which is separate from the electrical area and onto which the socket can be plugged, which provides operationally related advantages. Additionally, the slot extending between the electrical area and the handle can be used to guide the receptacle when the receptacle is inserted. The socket is simultaneously oriented into place. In addition, it can be provided that, in the plugged-in state, the electrical region and the connecting cable extending in the direction of extension of the electrical region are substantially arranged in a recessed position in an open slot arranged laterally in the handle shaft, and the separate handle is laterally Protrudes beyond the handle bar. Furthermore, it is preferred that the electrical area of the socket has a rectangular cross-section. It is also proposed that the handle protrudes beyond the electrical region of the socket along the longitudinal extent of the socket. In addition, it has proven to be beneficial for handling if the handle has an easy-grip profile and has the same easy-grip, cavity-like structure on the side opposite the profile.

Detailed ways

A vacuum cleaner 1 with a base unit G having a motor unit (not shown) and to which a filter chamber 2 is connected is firstly illustrated and described below with reference to FIG. 1 . The basic device G has an extension arm 3 which protrudes freely beyond the filter chamber 2 and forms a receptacle 4 at its free end. A handle rod St is inserted into this receptacle 4 , the insertion part of which handle rod St is formed as an aluminum profile part 5 . Instead, the connecting grip portion 6 is preferably formed by plastic injection moulding.

The lever St is conventionally movable telescopically in the extension arm 3 of the basic device G, and the lever St can be locked in the desired extended position. For this purpose, the handle rod St has locking notches 7 distributed evenly along its longitudinal direction and into which locking studs 8 arranged in the region of the receptacle 4 of the extension arm 3 can be inserted (see FIG. 19 ). The locking stud 8, spring-loaded in the locking direction, can be retracted by means of a rocker-mounted handle 9 in order to release the handle rod St.

The electrical connection is made via a connection cable 10 having a conventional electrical plug at one end and a device socket 11 at the other end. As can be seen in particular from the representation in FIGS. 3 and 4 , the device socket 11 has a groove 12 extending in the insertion direction r and separating the electrical field 13 from the handle 14 . The electrical region 13 here has a substantially rectangular cross section. A flat plug socket 15 arranged in this electrical area 13 and electrically conductively connected at the rear to the connecting cable 10 is open on a receiving base 17 which is set back from the free end surface 16 of the electrical area 13 .

In addition, the electrical region 13 extends substantially along the direction of axial extension of the connecting cable 10 .

The handle 14 of the device socket 11 extends substantially parallel to the electrical area 13, the slot 12 provided between the electrical area 13 and the handle 14 being open in the insertion direction r. Furthermore, to improve the grip, the handle 14 is provided with a profile 18 on the upper side. The handle 14 has a recess 19 on the underside.

It can be seen in particular from the illustration in FIGS. 6 and 7 that the handle 14 protrudes beyond the electrical area 13 in the direction of insertion r.

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

The device socket 11 of the connection cable 10 for the electrical contact connection with the fan motor arranged in the basic device G is connected to a device plug 22 which is arranged in the receptacle 4 of the extension arm 3 of the basic device and has a flat pin 21 , this device plug 22 is inserted into the device socket 11 and the flat pins 21 engage in the correspondingly aligned flat pin receptacles 15 in an electrically conductive manner.

According to the plan view of the socket 4 shown in FIG. 5 , the device plug 22 of the basic device is associated with a side area. In the engaged position, the slot 12 formed between the electrical area 13 and the handle 14 of the device socket 11 accommodates the wall portion of the extension arm 3 adjacent to the device plug 22, and is defined by a correspondingly formed and positioned extension arm 3 wall slot 23. Ribs 20 of the engaged handle provide further guidance of the device socket 11 in the insertion direction r.

It can be seen from FIGS. 6 and 7 that the insertion capability of the appliance socket 11 does not depend on whether the handle rod St of the vacuum cleaner 1 has been inserted for the use of the vacuum cleaner 1 as a handle-operated vacuum cleaner, or whether it is not dependent on the use of the vacuum cleaner 1 as an above-the-floor appliance. (above-foor appliance) Whether the handle rod St has been removed.

If the handle rod St has been inserted into the socket 4, the device socket 11, in particular the electrical area 13 and the connected connecting cable 10, is arranged in the socket groove 24, which is on the narrow side of the handle rod cross-section. The direction is opened outwards, and its opening degree and diameter are adapted to the size of the electrical area of the device socket 11. This insertion groove 24 extends over the entire length of the handle rod St, the groove cross-section being reduced in the region of the grip part 6 . This results in a relative movement of the inserted device socket 11 and the handle rod St, in particular the aluminum profile part 5, during the longitudinal telescopic movement of the handle rod St.

The insertion slot 24 is partially closed in the region of the grip portion 6 by fastening the bent portion 25, which protrudes in a tongue-like manner from the opposite longitudinal edge of the insertion slot 24, in this case in the grip. The end of the insertion groove portion on the holding portion 6 is located on both sides, and in the first example of each case, two fastening bent portions 25 are provided one next to the other along the longitudinal direction of the insertion groove 24, so that they protrude in opposite directions. In each case, a slot-shaped opening 26 corresponding to the diameter of the connecting cable 10 remains between these pairs of fastening bends 25 .

These fastening bends 25 allow the connection cable 10 to be stopped in the insertion groove 24 . However, the connection cable 10 can be removed as desired by overcoming the fastening bend 25 . The reinsertion of the connection cable 10 is facilitated by the elastic structure of the fastening bent portion 25 .

As shown in the drawings, another central fastening bend 25 may be provided between the two end pairs of fastening bends 25 .

Arranged on the lower broad side of the grip part 6 is a wrap-around profile 27 on which the connecting cable 10 can be wound in a space-saving manner when the vacuum cleaner 1 is not in use.

A bow-shaped handle portion 28 separate but integrally connected to the grip portion 6 is formed on the broad side of the grip portion 6 facing away from the fastening profile 27 .

The end of the insertion slot 24 remote from the device incorporates a cable protection outlet 29 which is gently curved in the radially outward direction and partly extends into the gripping portion 28, as a result, providing a device-side connection for the connection cable 10. anti-tangle device.

When the vacuum cleaner 1 is used as an above-floor device, that is, with the handle bar St detached, the power control of the motor unit provided in the basic device G is controlled by the power control provided in the basic device G and formed as a rotary controller device 30. In the illustrated embodiment, this power controller 30 can be used to set 4 power levels, with the off level designated A, two successive power levels designated L1 and L2, and the final power level designated L3.

Connected to this power controller 30 is a remote operation extension 31 which extends through the extension arm 3 up to the receptacle 4 and whose longitudinal axis extends along the extension of the axis of rotation y of the power controller 30 and thus parallel to Axis x of the handle bar. The remote operation extension 31 is housed in such a way that it cannot move longitudinally on the power controller 30 . However, angular displacement capabilities relative to each other are provided. This is achieved by the remote operation extension 31 comprising two longitudinal crosspieces 33 of plastic material construction, leaving a slot 32 between them, engaging in corresponding slot holes of the power controller 30 and thus allowing elastic deformation.

When the vacuum cleaner 1 is used as a hand-operated vacuum cleaner with a handle bar St, the remote operation extension 31 is used for the mechanical remote operation of the motor unit via a further power controller 34 which It is provided in the grip portion 28 of the handle bar St. This power control 34 is formed as a slide control by means of which the power level can be selected like the power control 30 on the device.

This sliding power control 34 acts on a remote operating lever 35 housed in the handlebar St. This remote operation lever is formed as a rotary lever and is installed in the tubular portion 36 of the handle lever St adjacent to the insertion groove 24 . Here the structural arrangement is chosen such that the remote operating lever 35 can be freely turned, but cannot be moved longitudinally in the tubular portion 36 .

The cooperation between the power controller 34 and the remote joystick 35 is achieved by means of a worm gear mechanism 37, as a result of which the linear motion of the power controller 34 is converted into a rotational movement of the remote joystick 35. As can be seen particularly from the schematic diagrams of FIGS. 12 and 21 , for this purpose the power controller 34 has a slider 39 which can slide in the guide window frame 38 and which at its end facing away from the power controller 34 The lower region has grooves 40 . The helical rib 41 provided at the end of the remote operating lever 35 engages in this groove by its T-shaped profile (see sectional view in FIG. 12 ). Through this interaction of the helical rib 41 and the slot 40 , the linear motion of the power controller 34 or its slider 39 is converted into a rotary motion of the remote operating lever 35 .

The end of the remote operating lever 35 facing away from the worm gear mechanism 37 ends at a certain distance from the corresponding free end of the handle rod St, which has an insertion hole 42 widening radially outwards at this end.

In addition, the remote operating lever 34 is formed in a tubular manner and has a radially inwardly extending rib 43 on the inner wall. The length of this axis-parallel rib 43 is adapted to the possible telescoping path of the handle rod St.

When the handle rod St is inserted into the receptacle 4 of the basic device G, the free end of the remote operation extension 31 of the basic device is first introduced through the insertion correlator 42 through the guide surface formed by the widened insertion hole 42 And then into the tubular remote control lever 35 . Finally, the rotational coupling between the remote operation extension 31 and the remote operation rod 35 is achieved by a rod rib 43 engaging in a radial groove 44 of the extension. Thereafter, the slide of the power controller 34 on the handle, which is converted by means of the worm gear mechanism 37, is transmitted to the power controller 30 on the device via the remote operation extension, and is transmitted to the power controller 30 via the electronic device. motor unit. The already described rotationally elastic coupling between the remote control extension 31 and the power controller 30 has proven to be advantageous here, since tolerances can thereby be accommodated in a non-destructive manner.

In order to align the remote control lever 35 and the remote control extension 31 with each other regardless of the position of the two power controls 30 and 34 in each case, a guide ramp 45 is formed on the remote control extension 31 in front of the slot 44 . This guide ramp is designed as a central rib 46 which extends perpendicularly to the axis of rotation and has guide surfaces 47 on both sides which transform into grooves 44 over the length of the wall. As a result of this configuration, in the different switching positions of the two power controls 30 and 34, the contact of the rib 43 of the guide rod with one of the two guide surfaces 47 and the subsequent continuous movement of the handle rod St in the insertion direction r This results in forward or rearward rotation of the remote operation extension 31 into slot 44 and rib 43 corresponding positions. Thus, the power control 30 on the device always assumes the position of the power control 34 when the handle rod St is inserted.

As mentioned above, the vacuum cleaner 1 shown and described has three active power levels L1 to L3. According to the invention, the final power level L3 can only be set after the mechanical obstacle has been overcome, in particular in the case of setting with the power control 34 on the handle bar. For this purpose, this power controller has a rib 49 which protrudes upwards in the direction of the actuating protrusion 48 of the power controller 34 and which abuts against the edge of the power controller actuating gap 51 when the power level L2 is reached. Peripheral edge 50 . When the power control 34 is activated with deliberate depression, the rib 49 runs under this barrier, thus reaching the desired final power level L3 (see FIG. 22 ). The obstacle chosen in this way can therefore only be overcome intentionally.

The disclosures of the related/accompanying priority documents (copies of earlier applications) are also included in their entirety in the disclosure content of the present application, and it is also intended that features of these documents be included in the claims of the present application .
