The invention relates to a hand-held electrical device, in particular a cleaning device, with a housing and a handle arranged on the housing, which is displaceable relative to the housing, the handle being mounted on the housing by means of an annular holding device which holds the housing in at least the circumferential direction partially surrounds, wherein the housing and the holding device have corresponding electrical contacts, wherein at least the housing or the holding device has a plurality of electrical contacts, of which at least one electrical contact, depending on a displacement position of the holding device, with an electrical contact of the holding device or the housing is connectable.

State of the art

Hand-held electrical devices are known in the prior art, for example, as cleaning devices or electrical tools. An electrical device according to the preamble of claim 1 is from EP 2329923 A2 known. In particular, hand-held electrical appliances include vacuum cleaners, mopping devices, polishing devices, screwdrivers, drills, hammer drills and the like.

For example, drilling machines are known in the prior art which have a handle which is carried by a holding device rotatably mounted on the drilling machine and has a longitudinal extension in a radial direction to the annular holding device. The handle can be rotated about its longitudinal axis to the holding device on the drill to clamp. Such an electrical device, for example, reveals the DE 10 2009 000 598 A1 .

Furthermore, cleaning devices are known which are designed as battery-operated devices. These are preferably used for cleaning above-floor surfaces, with the user carrying the cleaning device in his hand. For this purpose, the cleaning device is carried using the handle arranged on the housing and guided over the surface to be cleaned.

The disclosure document DE 10 2015 118 621 A1 For example, discloses such an electrical device with a handle which can be pivoted as required from a rest position in which it is placed against the device housing into a use position in which the handle protrudes from the device housing and can be grasped by the user's hand. In the swung-out position of use, a linear displacement, rotation or telescoping extension of the handle takes place relative to the device housing in order to lock the swung-out position of use so that the handle does not undesirably swing back into the rest position and possibly pinch the user's hand.
The printed matter EP 2329923 A2 , DE 10 2013 202832 A1 and DE 10 2004 003202 A1 further disclose electrical devices with a handle which is held with an annular holding device on a defined peripheral area of the device housing. The holding device can be fixed in a desired rotational position.

Summary of the invention

Based on the aforementioned prior art, the object of the invention is to improve the manageability of a hand-held electrical device improve, in particular so that a user can use further variants of using the device.

To solve the aforementioned problem, it is proposed that the handle is pivotally mounted on the holding device relative to the holding device, namely in such a way that the handle is between a position in which the handle is aligned parallel to a longitudinal extension of the device and a position in which the handle is oriented orthogonally to the longitudinal extent of the device, can be pivoted, wherein the handle is pivotable about an axis which is oriented orthogonally to the longitudinal axis of the device and radially intersects the annular holding device, and wherein the holding device is additionally attached to the housing in Is mounted linearly displaceable in the direction of a longitudinal extent of the electrical device.

The housing and the holding device also have corresponding electrical contacts which, depending on the axial position or circumferential position of the holding device on the housing, provide an electrical connection between an electrical component of the electrical device and an electrical component of the holding device or the handle. Particularly preferably, the electrical contacts can also be integrated into the connecting elements described below, so that when two corresponding connecting elements are connected, electrical contacting also occurs at the same time.

The handle is pivotably mounted on the holding device. This not only allows a relative displacement of the holding device on the housing, but also a displacement of the handle relative to the holding device. The handle can be switched between a position in which the handle is aligned parallel to the longitudinal extent of the housing is, and pivoted to a position in which the handle is aligned orthogonally to the longitudinal extent of the housing. The handle can, for example, be set in various defined angular positions, preferably in 45° increments. This rotation can be made possible in that, for example, when an unlocking element of the handle is actuated, a clamping force between the handle and the holding device is canceled. Depending on which side a user wants to hold and operate the electrical appliance from, an individual position of the handle on the electrical appliance can be provided.

The holding device is also mounted on the housing of the electrical device in a linearly displaceable manner in the direction of a longitudinal extent of the electrical device. As a result, the handle can be moved in the axial direction of the electrical device in order to advantageously vary a gripping position for a user. The linear displaceability is preferably provided in a length range of at least 25 mm and up to 300 mm. For this purpose, the housing of the electrical device is advantageously cylindrical, at least with respect to an axial length section, so that a linear displacement on the housing is possible. The proposed design makes it possible to significantly vary the position of the handle relative to the center of gravity of the electrical device, so that comfortable device guidance via the handle is possible in different application situations. For example, the handle can be advantageously adjusted when changing from a floor application to an overhead application of the electrical device. In a floor application, for example, a position of the center of gravity close to the user's wrist is advantageous. When used in an area of a ceiling, a center of gravity between the user's elbow and wrist is advantageous. In other applications, the center of gravity can be between the hand and wrist be beneficial to the user. This results in a flexible adjustment of the position of the handle, which takes into account ergonomic aspects when handling the electrical device by reducing the torque and forces acting on the user's body, in particular his wrist.

Furthermore, it can be provided that the holding device is additionally mounted on the housing so that it can rotate in the circumferential direction of the electrical device. With this configuration, the holding device can not only be displaced in the longitudinal direction of the electrical device, but can also be rotated around the housing of the electrical device, so that the handle arranged on the holding device changes its position in the circumferential direction of the housing of the electrical device. This configuration allows the position of the handle to be adapted, for example, to the needs of left-handed or right-handed people. Depending on which attack side a user wants to guide the electrical device, the peripheral section of the housing can be selected on which the handle is positioned particularly advantageously. Likewise, the electrical device can also be gripped from above or below, for example, in relation to a usual direction of use of the electrical device.

The holding device can be designed in a closed annular shape, but alternatively it can also only span a partial peripheral area of the housing, so that an open C-shape of the holding device results. The holding device and thus also the handle can thus be moved over the outer surface of the housing and/or rotated around the housing. This makes it possible to set different handle positions relative to the center of gravity of the device according to a current work task, which makes handling easier.

Preferably, a sliding element is arranged between the outer wall of the housing and the inner wall of the holding device or a sliding layer is formed, which prevents damage or scratching of the housing by the holding device. In particular, the holding device can have a coating on the inside facing towards the housing, which prevents material abrasion on the housing of the electrical device. Such a sliding coating can be, for example, a sliding varnish, which reduces frictional forces between the housing and the holding device. Alternatively, however, the holding device can also be made, at least partially, from an elastomer, so that, for example, scratching of the housing is prevented.

It can be provided that the holding device holds the device housing relative to a center point orthogonal to the longitudinal extent of the Device level completely surrounds the device. However, the holding device can also be designed as a segmented element, which transmits a holding force to a fixed bearing of the holding device or the housing through peripheral segments lying opposite the center point.

It is proposed that the holding device is held on the housing in a positive and/or non-positive manner. In the case of a form-fitting holder, an inside of the holding device has a contour that corresponds to a contour of the outside of the housing, so that corresponding shaped elements of the holding device and the housing are suitable for fixing a set position of the holding device on the housing. Alternatively or additionally, it is possible for the holding device to be held non-positively on the housing. For this purpose, the holding device can be clamped onto the housing, for example. Particularly preferred is a combination of a positive and a non-positive holder, so that the position of the holding device and thus also the position of the handle can be fixed in defined positions. A clamping force of the holding device is preferably additionally supported by the positive holder, so that the clamping force can be reduced overall, for example to reduce damage to the housing or to make it easier for a user to loosen a clamping fastening.

In particular, it is proposed that a diameter of the annular holding device is reversibly variable, with the holding device being designed in particular as a clamp and/or as a snap ring acted upon by a restoring spring force. The rotational and/or translational movement of the holding device is made possible by a force connection between the holding device and the housing of the electrical device. The holding device is on the housing during a normal state clamped and is spread open to enable adjustment. The spreading can take place, for example, by means of an unlocking element which is driven in a wedge shape into an opening in the annular holding device. The holding device can consist of several concentrically arranged layers, with an outer layer forming a receiving element for an inner layer. The inner layer has clamping elements for connection to the housing of the electrical device, while the outer layer remains stationary relative to the housing. The holding device or its clamping function can be released by actuating an unlocking element, which, for example, spreads out a snap ring that is subjected to a restoring spring force and which, following the restoring force, fits positively and non-positively around the device housing. Furthermore, the holding device can also be a clamp, which is pulled against the housing, for example by means of a screw or ratchet mechanism.

Furthermore, it is proposed that the holding device can be displaced relative to the housing by means of a tongue-and-groove connection, with at least one groove being formed on the housing or the holding device in the axial direction or circumferential direction, into which a projection of the holding device or the housing engages . The groove forms a guide link for the corresponding projection. The groove can be formed either in the housing or the holding device or, accordingly, the projection either on the housing or the holding device. The groove can, for example, extend in the axial direction, so that a linear displacement of the holding device relative to the housing is made possible. Furthermore, a groove can be formed in the circumferential direction of the housing or the holding device, so that rotation of the holding device around the housing is made possible. It is also possible to form several grooves on the holding device or the housing, which intersect and one Specify a grid with defined displacement paths for the holding device on the housing.

It is further proposed that the housing and the holding device have corresponding connecting elements, possibly in conjunction with corresponding electrical contacts, wherein at least the housing or the holding device has a plurality of connecting elements and electrical contacts, of which at least one connecting element and / or an electrical Contact can be connected to a connecting element and/or an electrical contact of the holding device or the housing depending on a displacement position of the holding device. For example, the housing can provide a plurality of connecting elements, while the holding device only has a single corresponding connecting element. In the event of an axial displacement of the holding device or a rotation of the holding device, the individual connecting element of the holding device can engage in the connecting elements of the housing arranged one behind the other. This results in a gradual adjustment of the position of the holding device on the housing. Furthermore, it is also possible for both the housing and the holding device to have several connecting elements, so that the displacement range of the holding device can be additionally enlarged or a gradation of different positions of the holding device can be refined. It is also possible, conversely, for the housing to provide only a single connecting element and the holding device to provide a plurality of connecting elements. The connecting elements can, for example, be material recesses on the one hand and material projections on the other hand, which can engage in the corresponding material recesses. For example, the material projections are designed as locking bolts that can be displaced in the radial direction, preferably spring-loaded, and which enable the holding device to be displaced from a protruding one Position can be shifted into a recessed position in order to release the projection from the recess. Furthermore, it is also possible for the corresponding connecting elements to be part of an external toothing of the housing or internal toothing of the holding device. The corresponding teeth of the housing and the holding device can mesh in a variety of different rotational positions, with the toothing being able to be loosened either by spreading the annular holding device or by overcoming a breakaway torque. The material recesses can be designed as grooves in relation to an axial direction or circumferential direction, so that a continuous adjustment is possible in one direction and a gradual adjustment in a direction orthogonal thereto, which is predetermined by the distances between the material recesses or locking teeth. For example, in the circumferential direction of the housing, a toothing can be formed with teeth lying one behind the other in the circumferential direction, which form grooves in relation to the axial direction.

Furthermore, it is proposed that the holding device has two ring elements arranged concentrically one inside the other, of which a first radially inner ring element has an electrical contact rail which has an electrical connection to an energy source of the electrical device, and wherein a second radially outer ring element has a displaceable along the contact rail has an electrical current collector which maintains electrical contact with the contact rail during a displacement movement of the second ring element relative to the first ring element. The current collector is preferably permanently connected to the contact rail, so that energy is transferred regardless of the current position of the holding device relative to the housing. According to this embodiment, the electrical contact of the electrical device for the holding device is always stationary. The rotational and translational movement of the holding device can also be achieved via a frictional connection and/or positive connection take place. The electrical contact can preferably be integrated into the clamping mechanism of the holding device. In order to be able to maintain electrical contact even in the event of a linear displacement in the longitudinal direction of the electrical device, electrical contacts are arranged on the housing, preferably over a certain length, which allow a gradual connection to the holding device, in particular its annular contact rail.

Furthermore, it is proposed that the holding device and/or the handle has an electrical switch for controlling an electrical load of the electrical device. According to one embodiment, the electrical switch is, for example, an on-off switch for actuating an electrical load of the electrical device. For example, a motor-fan unit of the electrical device can be switched on and off using the electrical switch. The electrical switch can be designed as a removable element, so that it also allows remote control of the electrical device via a wireless communication connection. The switch can also have a wireless communication device for connecting to other electrical devices. In addition, due to the electrical connection between the housing of the electrical device and the holding device or the handle, it is also possible to form a display on the holding device or the handle on which information can be presented to a user and/or the user can make entries.

Description of the embodiments

Figure 1 shows an exemplary hand-held electrical device 1, namely here for example a cordless vacuum cleaner, which can be used both for cleaning floor surfaces and for cleaning above-floor surfaces. The electrical device 1 has a housing 2 with a suction mouth 23, which can be guided over a surface to be cleaned. The housing 2 of the electrical device 1 has a molded housing handle 24, which carries a switch 21 for switching a motor-fan unit (not shown) of the electrical device 1 on and off. The housing 2 of the electrical device 1 is essentially cylindrical, with a partial section of the housing 2 having a constant diameter in the direction of a longitudinal extent. The housing 2 carries a holding device 4 with a handle 3. The holding device 4 surrounds the housing 2 concentrically and can be displaced relative to the housing 2 both in the direction of the longitudinal extent of the housing 2 and in its circumferential direction. The holding device 4 consists of two concentrically arranged ring elements 17, 18, namely a radially inner ring element 17 and a radially outer ring element 18. The ring elements 17, 18 can, for example, be made of an elastomer and lie against one another and / or be made of a hard plastic . The outer ring element 18 is designed as a closed ring, while the inner ring element 17 has a C-shape with a ring opening 25. The inner ring element 17 is a spring ring with a restoring force, the restoring force of which is directed inwards in order to reduce the ring opening 25 to the smallest possible circumferential section. The handle 3 has an unlocking element 22 which engages in the ring opening 25. The unlocking element 22 reaches through a through opening 26 (see Figure 3 ) of the second ring element 18 and is pushed radially inwards into the ring opening 25 of the first ring element 17 when actuated. The free end region of the unlocking element 22 engaging in the ring opening 25 is designed in a wedge shape, so that the inner ring element 17 expands when the unlocking element 22 is actuated, ie here the unlocking element 22 is pressed down. The clamping force acting on the housing 2 through the holding device 4 is reduced or eliminated, so that the user can move and/or rotate the holding device 4 relative to the housing. The spreading of the first, inner ring element 17 is made possible, for example, by the elastic design of both ring elements 17, 18 or by a free annular gap between the two ring elements 17, 18. In addition, when the unlocking element 22 is actuated, a clamping force between the handle 3 and the second, outer ring element 18 of the holding device 4 is simultaneously reduced, so that the handle 3 can be displaced relative to the holding device 4 and the housing 2, namely here for example, can be rotated about an axis of rotation of the handle 3.

The holding device 4 and the handle 3 are thus displaceable relative to each other and also relative to the housing 2, so that a user of the electrical device 1 can make an individual adjustment of the position of the handle 3 on the housing 2. In particular, it is possible to move the handle 3 relative to a center of gravity of the electrical device 1 in such a way that advantageous and ergonomic operation and guidance of the electrical device 1 is possible for the respective floor or above-ground application. In order to protect the surface of the housing 2 from damage due to the displacement of the holding device 4, it can additionally be provided that the holding device 4 carries a sliding element or a sliding coating on the inside, ie on the inner wall of the inner ring element 17, which on the one hand, for example, carries a frictional force between the housing 2 and the holding device 4 are reduced and, on the other hand, a displacement of the holding device 4 is made possible relative to the housing 2.

The Figures 2 to 5 show different views of the in Figure 1 holding device 4 shown ( Figures 2 and 3 ) or enlarged partial sections of the holding device 4 ( Figures 4 and 5 ). The functioning of the clamping mechanism of the holding device 4 is explained in relation to Figures 3 to 5 explained in more detail.

The Figures 3 and 4 show a state of the holding device 4 clamped against the housing 2. The unlocking element 22 is still outside the ring opening 25 of the inner ring element 17, so that the inner ring element 17 is relaxed. By actuating the unlocking element 22, a user can then expand the inner ring element 17, which is designed as a snap ring. For this purpose, the unlocking element 22 is pressed into the holding device 4, the free end region of the unlocking element 22 initially passing through the through opening 26 of the second ring element 18, preferably without contact, and as the displacement continues, it contacts the inner ring element 17 and expands it against its restoring force. As a result of the spreading, the diameter of the inner ring element 17 changes, so that the clamping force of the holding device 4 on the housing 2 of the electrical device 1 is eliminated or at least reduced. This makes it possible for the user to move the holding device 4 relative to the housing 2, namely in the axial and/or circumferential direction of the housing 2. In addition, the handle 3 can preferably also be rotated relative to the holding device 4. The spread state of the inner ring element 17 shows Figure 5 . When the unlocking element 22 is then released again, the inner ring element 17 pushes together again following the restoring spring force, so that its diameter is reduced. As a result, the unlocking element 22 is pushed out of the ring opening 25. The inner ring element 17 then presses again against the housing 2 with a minimum diameter, so that there is a non-positive connection to the housing 2. The unlocking element 22 can preferably be mounted on the handle 3 via a restoring element (not shown), so that when the unlocking element 22 is released, the unlocking element 22 also moves out of the outer ring element 18.

The Figures 6 and 7 show a second embodiment in which a connecting element 12 of a holding device 4 designed as a spring pin engages in one of several available connecting elements 7 to 11 of the housing 2 of the electrical device 1. The connecting element 12 is designed in the manner of a locking bolt which, following a restoring force of an associated spring element 27, engages in a material recess in the housing 2, namely in a connecting element 9. The connecting element 12 can be released from the connecting element 9 by actuating an unlocking element 22 arranged on the handle 3. For this purpose, for example, there is a mechanical connection (not shown) guided by the holding device 4 between the unlocking element 22 and the connecting element 12 and / or the spring element 27, so that when the unlocking element 22 is actuated, a compression of the spring element 27 is caused and thus a loosening of the connecting element 12 from the connecting element 9 is made possible. For locking the holding device 4 on the housing 2, for example, five different positions are available here, which are defined by the connecting elements 7 to 11. The connecting elements 7 to 11 can be designed, for example, as essentially punctiform material recesses, or alternatively as grooves running in the axial direction of the housing 2. In the case of grooves, the clamping force for preventing axial displacement of the holding device 4 relative to the housing 2 is provided by the spring element 27 or the associated connecting element 12.

It can also be provided that the connecting elements 7 to 11 of the housing have electrical contacts via which energy can be transferred from an energy source of the electrical device 1 to the holding device 4 and/or the handle 3. For this purpose, the connecting element 12 of the holding device 4 can also be designed as an electrical contact. In addition to a power supply, such electrical contact can also be used, for example, to transmit an electrical pulse from a switch 21 of the handle 3 to the electrical device 1. The in Figure 6 Switch 21 shown can, for example, be an on-off switch of the electrical device 1, which effects control of an electrical consumer of the electrical device 1 via the connecting elements 7 to 12 designed as electrical contacts, for example switching a motor-fan unit on/off Electrical device 1. In addition, a display, an optical display device or the like arranged on the holding device 4 or the handle 3 can also be supplied with energy via such an electrical connection.

The Figures 8 and 9 show a further embodiment of a holding device 4. The holding device 4 is interlocked with corresponding connecting elements 7 to 11 of the housing 2 via a plurality of connecting elements 12 to 16. The connecting elements 7 to 16 engage with one another and lock the holding device 4 in the circumferential direction on the housing 2. A breakaway torque can be defined via the shape of the tooth contour, at which the corresponding connecting elements 7 to 16 can detach from one another and a rotation of the holding device 4 relative to the housing 2 is possible. This form fit thus defines a specific torque which is required for the rotation of the holding device 4. In this embodiment, an additional unlocking element 22 can be dispensed with.

Figure 10 shows a further embodiment in which the housing 2 of the electrical device 1 has a total of four connecting elements 7 to 10 designed as material recesses. The holding device 4 correspondingly has two connecting elements 12, 13, which can engage as material projections in the connecting elements 7 to 10 of the housing 2. In order to enable rotation of the holding device 4 relative to the housing 2, a portion of a handle 3 is inserted into an annular opening 25 of the holding device 4. The diameter of the holding device 4 is increased and the connecting elements 12, 13 of the holding device 4 can detach from the connecting elements 7, 9 of the housing 2. According to this embodiment, it can be provided, for example, that the connecting elements 7 to 10 are designed as elongated grooves in the axial direction of the housing 2 (i.e. perpendicular to the plane of the sheet). It is also possible for the holding device 4 and/or the housing 2 to have connecting elements 7 to 10 or 12, 13 lying one behind the other in relation to the axial direction, which enable the holding device 4 to be locked gradually on the housing 2 in the longitudinal direction of the housing 2 .

Figure 11 shows a further embodiment of a holding device 4, which has an inner ring element 17 and an outer ring element 18. The inner ring element 17 has a contact rail 19, which can be connected to a power supply of the electrical device 1 via a connecting element 12, which comprises an electrical contact element. For this purpose, there is preferably a corresponding connecting element (not shown) on the housing 2 of the electrical device 1, so that the contact rail 19 can be supplied with power. The inner ring element 17 sits stationary on the housing 2 of the electrical device 1, the outer ring element 18 being rotatable relative to the inner ring element 17 and thus also the contact rail 19. The outer ring element 18 has two current collectors 20, which are the contact rail 19 of the inner ring element 17 contact in a sliding manner. As a result, the current collectors 20 remain in contact with the contact rail 19 even when the outer ring element 18 rotates. The current collectors 20 can be connected by a line (not shown) guided in the outer ring element 18 to, for example, an electrical switch 21 of the handle 3, via which For example, an electrical consumer of the electrical device 1 can be controlled. For example, it is possible to transmit a control signal to a motor-fan unit of the electrical device 1 by pressing the electrical switch 21. Likewise, electronic display elements (not shown), such as a battery charge level indicator, a display or the like, can also be provided on the holding device 4, which are supplied with electrical energy from the electrical device 1 via the current collector 20 and the contact rail 19.

Although the invention has been illustrated in the figures using a cleaning device as an example, it is understood that the electrical device 1 can also be another device, for example a power tool such as a drill, a hammer drill or others.
