Description

Technical Field

[0001] The present invention relates to a surface processing apparatus having an apparatus housing and a handle pivotally supported on the apparatus housing via a joint, wherein the joint has an apparatus part belonging to the apparatus housing and a handle part belonging to the handle, wherein the apparatus part and the handle part are fixable relative to each other in at least two different positions by a fixing element, wherein the fixing element, the apparatus part, and the handle part are designed as cylindrical and coaxially arranged with respect to at least a sub-region in which they interact to provide the function of the joint, wherein the handle part is rotatably supported on the apparatus part, and wherein the fixing element is designed, in particular by utilizing the restoring force of a spring element arranged in the middle, to press the handle part against the apparatus part such that the rotatability of the handle part is reversibly prevented. Background Technology

[0002] Surface treatment equipment is well known in the prior art. These surface treatment devices typically have a pivotally supported handle to allow the user to perform different treatment tasks, for example, in areas of a floor surface or in areas of a surface above the ground. For example, the handle may be oriented in an extension of the device housing on one hand, or pivoted close to the device housing on the other hand, to provide, for example, a more compact surface treatment device for surface treatment above the ground. To secure the desired position, the handle is held in place by a fixing element, wherein locking or pressing connections are known to be used.

[0003] For example, patent document EP 2 220 986 B1 discloses a vacuum cleaner with a handle that can pivot 180 degrees, the handle forming an extension of the device housing in a first position and pivoting substantially parallel to the device housing in a second position. Patent document DE 10 35 330 B also discloses, for example, a handheld vacuum cleaner with a pivotable handle. A sub-region of the handle can be pivoted on the base device, thereby positioning the handle at a distance relative to the base device and adapting it as a handle. A locking device is provided on the base device for securing the handle in the pivoted position. Summary of the Invention

[0004] Based on the aforementioned prior art, there is a need to provide a surface treatment device with the advantageous possibility of securing a handle. The pivoting system of this handle is particularly preferably operable intuitively.

[0005] To address the aforementioned technical problems, it is suggested that the handle and the device be designed as hollow cylindrical bodies with respect to their cylindrical sub-regions, wherein the handle is inserted into the device in at least one axial segment, and wherein the fixing element is circumferentially surrounded by a spring element that is axially supported on a stop of the fixing element on one side and on a stop of the handle on the other side.

[0006] The joint for the handle essentially consists of three mechanically connected components: the device component, the handle component, and the fixing element. The handle component is rotatable relative to the device component, allowing the handle to pivot relative to the device housing. The fixing element optionally secures the handle component to the device component in one of at least two defined positions to ensure that the handle does not unintentionally pivot relative to the device housing when the user uses the surface processing device. The force required to secure the handle component relative to the device component is preferably provided by a spring element acting on a sub-region of the fixing element and on a sub-region of the handle component. For example, the spring element can be a helical spring extending between the radial protrusions of the fixing element and the handle component. The spring element of the fixing element thus acts indirectly on the device component through the handle component. Particularly preferably, a sub-region of the device component, such as a radial shoulder, can be clamped between another sub-region of the handle component and the fixing element, wherein the clamping force is provided by the spring element. Particularly preferably, the fixing element can be designed, for example, as a substantially cylindrical member, which preferably has radial protrusions on its end sides, i.e., in the region on its end sides, which serve as end stops for the spring element and the handle or device component. Thus, relative to the axial direction, a sub-region of the spring element on one side and the handle or device component on the other side lies between the end stops. To subsequently release the handle from the fixed position, the user can overcome the restoring force to compress the spring element and provide an axial distance between the handle and device component, which allows the handle to rotate relative to the device component.

[0007] According to the invention, the handle is inserted into the device component in at least one axial section. This brings several advantages. On the one hand, the device component thus serves as a support for the handle and allows the handle to rotate relative to the device. On the other hand, this design allows the joint to be constructed particularly small and can be integrated into the device housing in a space-saving manner. Advantageously, this creates an overlap of sub-regions along the axial direction of the handle and the device. This overlap can preferably allow the handle to be inserted into the device with approximately two-thirds of its axial length. Due to the supporting function of the device, the handle and the device can also be oriented coaxially with each other particularly easily and without skewing when the handle rotates. Preferably, the cylindrical fixing element also overlaps axially relative to the handle, i.e., is at least partially located within the cylindrical handle, in order to achieve the aforementioned advantageous effects, i.e., coaxial orientation on the one hand and reduction of the axial length of the joint on the other. The fixing element can be particularly preferably, for example, a rotatable fixing pin located in the cylindrical sub-region of the handle.

[0008] Furthermore, the fixing element is circumferentially surrounded by a spring element, which is axially supported on both the stop of the fixing element and the stop of the handle. The spring element is preferably designed as a helical spring, which surrounds the fixing element and is supported on the stops at the mating ends of the fixing element and the handle.

[0009] It is proposed that the handle be movable both axially and circumferentially relative to the device. According to this design, the handle can therefore be moved axially to create a gap between the handle and the device, allowing the handle to rotate relative to the device. This axial movement is opposite to the restoring force of the spring element. The rotation of the handle is used to pivot the handle relative to the device housing of the face processing equipment, i.e., to the position required for the user to perform the current face processing task.

[0010] According to one embodiment, the fixing element is circumferentially immovable from the handle. With this design, the handle and fixing element thus form a component unit that can rotate together about a common cylindrical axis. The axial mobility of the handle relative to the fixing element remains unaffected. For example, the peripheral wall of the cylindrical fixing element may have a protrusion that engages in a fitting recess in the inner wall of the handle. The recess in the handle is preferably designed as a longitudinal groove extending in the axial direction, so that the protrusion of the fixing element can be moved axially relative to the handle. This allows the handle to move against the restoring force of the spring element of the fixing element, enabling the handle to be released and pivoted relative to the device housing.

[0011] Furthermore, it can be specified that the fixing element has a locking element for reversibly securing the fixing element in a defined end position relative to the device component. According to this design, the fixing element or handle component is thus secured in a specific rotational position not solely by the clamping force of the spring element but also by the proposed additional locking element.

[0012] For example, the locking element may be a pivotable stop pawl that engages in a fitting sub-region of the device component. The locking element may, for example, be arranged on the end side of the fixing element and point radially outward beyond the outer periphery of the end side of the fixing element so as to engage in a fitting recess in the device component. The locking element may be pivoted such that the engagement of the locking element can be released from the fitting sub-region of the device component and the locking element can rotate relative to the device component. The locking element is preferably associated with a spring element that typically holds the locking element in the locked position engaged in the sub-region of the device component. Only when the user acts on the locking element to release the engagement is the restoring force of the spring element counteracted by the applied force, and the lock can be released. For example, the mobility of the locking element may be limited to a defined pivot angle. For this purpose, a mechanical stop may be provided on the fixing element, limiting the pivot angle. For example, a maximum pivot angle of, for example, 20 degrees may be specified.

[0013] Alternatively, it is suggested that the locking element is a radially movable stop pin that engages in a suitable sub-region of the device component. In particular, the locking element may also have two opposing locking sub-elements connected to each other by a connector. In the locked position, the locking element engages in overlapping radially overlapping locking recesses in the device component and the handle component. A spring element associated with the locking element, for example, radially presses the locking element or locking sub-elements outward, such that the locking element or these locking sub-elements are securely seated in the locking recesses. This prevents rotational movement of the handle component relative to the device component. Only when the user acts on the locking element to disengage, the operating force counteracts the restoring force of the spring element and disengages the locking engagement by moving the locking element back from the locking recesses. For example, the connector arranged between the two opposing locking sub-elements may be designed to be flexible and deformable by applying a force orthogonal to the longitudinal extension of the connector, such that the distance between the opposing locking sub-elements (relative to the radial direction) is shortened and the locking sub-elements can be removed from the locking recesses. For example, by axial movement of the actuating element and contact with the connecting member, the restoring force of the spring element can be overcome to shorten the connecting member, allowing the connecting sub-element to retract from the locking recess and the fixed element, which is fixedly connected to the locking element, to rotate relative to the equipment component. Alternative modes of operation are possible. Other possible variations are described in detail below with reference to the accompanying drawings. The locking element or connecting member may, for example, have an actuating profile that converts the movement of the actuating element, particularly axial movement, into radial movement of the locking element.

[0014] Furthermore, it is suggested that the device component has two locking recesses spaced 180 degrees apart circumferentially, which are used to accommodate at least one sub-region of the locking element. The positions of these two locking recesses correspond here to preferred positions of the handle relative to the device housing, namely, a first position in which the handle is oriented in the extension of the longitudinal extension of the base of the surface treatment device, and a second position in which the handle is pivoted on the base and oriented parallel to it in the opposite direction. Thus, the surface treatment device can be used, for example, on the one hand, such that it is supported on the surface to be treated, for example, as a surface treatment device that rolls on the surface to be cleaned, or on the other hand, as a surface treatment device that is lifted from the surface to be treated during surface treatment and can be guided as a compact unit, for example, along a surface higher than the ground.

[0015] Finally, it can be specified that the fixing element is equipped with an actuating element for manipulating the locking element, wherein the actuating element is guided from the locking element to the outer wall of the handle. According to one design, the actuating element can be, for example, a button, one end of which is fitted into the contour of the handle. By pressing the actuating element downward, the user can act on the locking element and release it from the fitted sub-area of ​​the device, thereby allowing the handle to be pivoted. For example, the actuating element can be pressed down a few millimeters to achieve movement of the locking element, particularly pivoting or radial movement. The actuating element can preferably be actuated only until the locking element strikes the end stop of the mechanism. Attached Figure Description

[0033] Figure 1 An exemplary surface treatment device 1 is shown, which is designed herein as a cleaning device, such as a handheld vacuum cleaner. The surface treatment device 1 has a base device 15 and an interface 16 for accessory devices (not shown). The accessory devices can be detachably connected to the base device 15 via the interface 16. The accessory devices can be, for example, a suction nozzle and / or a cleaning element such as a rotating brush roller. The operation of the surface treatment device 1 is possible with or without the accessory devices. For example, the surface treatment device 1 can be used to treat floor surfaces with the accessory devices, or it can be used, for example, for cleaning surfaces above the ground, such as vacuuming shelves, without the attached accessory devices. The base device 15 has a handle 4 on which the user can guide, for example, moving the surface treatment device 1 over the surface to be cleaned during normal operation. In this process, the user typically moves the surface treatment device 1 back and forth alternately in opposite directions. Switching elements (not shown in detail here), preferably power switches for the power consumption of the surface treatment device 1, such as motors for fans, cleaning elements, etc., can be arranged on the handle 4. In addition, a conversion device can be provided, through which the user can select the processing intensity for surface treatment. The surface treatment device 1 can be connected to a household power supply in a conventional manner via a power plug and / or has a battery for providing power to power-consuming appliances.

[0034] The handle 4 can pivot about the joint 3. The joint 3 is used to pivot the handle 4 relative to the device housing 2 to, for example, one of the two defined end positions. In principle, additional end positions can also be provided. Figure 1The first end position of the handle 4 is shown, in which the handle is pivoted out into the extension of the longitudinal extension of the base device 15 of the surface treatment device 1. The second end position is shown in dashed lines, in which the handle 4 is pivoted close to the base device 15. The handle 4 forms an extension in the aforementioned pivoted position, thus eliminating the need for the user to bend over towards the floor surface to be cleaned. In contrast, the second end position of the handle 4, shown in dashed lines, is pivoted at a 180-degree angle from the first end position, thus the handle 4 is pivoted close to the base device 15, i.e., the handle 4 is oriented parallel to the opposite side of the first end position. In this position, the user can preferably use the surface treatment device 1 for surface applications above the ground, where a compact device is advantageous, with its center of gravity close to the user's hand.

[0035] To enable the handle 4 to pivot to this 180-degree opposing position, the joint 3 has a device 5 and a handle 6, as shown in the figure below. The device 5 is, for example, a fixed component of the base device 15 and is constructed as a single piece to an adjacent sub-region of the device housing 2. For example, the device 5 can be formed onto the device housing 2 of the surface treatment device 1. Alternatively, the device 5 can be connected to the adjacent sub-region of the device housing 2 using connection techniques such as adhesive, screwing, or locking. Importantly, the device 5 cannot be moved relative to the base device 15. In contrast, the handle 6 of the joint 3 can pivot relative to the base device 15 after being unlocked by the operating element 13. The handle 6 is part of the handle 4 and is fixedly connected to the handle, for example, by a single-piece design.

[0036] As in Figure 2As shown in more detail, in addition to the device 5 and the handle 6, the joint 3 also has a fixing element 7 for securing the handle 6 relative to the device 5. The device 5, handle 6, and fixing element 7 are designed to be substantially cylindrical and arranged coaxially with each other, such that their cylindrical axes lie on a common straight line. To achieve a small structural size and a non-skewed function of the joint 3, the device 5 also serves as a support for the handle 6. The handle 6 itself, in turn, serves as a support for the fixing element 7. As shown here, the fixing element 7 can preferably be designed as a hollow cylindrical body with a cable channel 28, thereby allowing the cable to be routed from the handle 4, particularly the conversion device arranged there, to the base device 15 of the surface treatment equipment 1. Thus, the joint 3 serves, on the one hand, the pivotability of the handle 4 relative to the device housing 2, and on the other hand, the cable routing from the handle 4 to the base device 15 of the surface treatment equipment 1. The fixing element 7 also has two stops 9, which here project radially outward, for example, in the region on the end side of the fixing element 7. Therefore, the stop 9 has a larger outer diameter compared to the shaft section adjacent to the fixed element 7 in the axial direction a. A radially inwardly pointing stop 10 of the handle 6 and a protrusion 17 of the device 5 are fitted between the stops 9 on both ends of the fixed element 7. The protrusion 17 of the device 5 is supported on the stops 9 of the fixed element 7. The fixed element 7 is also equipped with a spring element 8, which is advantageously designed as a helical spring that surrounds the cylindrical fixed element 7 with respect to both the circumferential direction u and the axial direction a. The handle 6 and the device 5 are fixed to each other by the spring element 8 and the fixed element 7, such that relative movement in the circumferential direction u and the axial direction a is prevented by the restoring force of the spring element 8 and the friction between the device 5 and the handle 6.

[0037] The fixing element 7 has a locking element 11, which is designed here as a pivotable stop pawl relative to the fixing element 7. This stop pawl is held in the locked position as shown by the restoring force of the spring element 18. The spring element 18 is supported on the abutment area 26 of the fixing element 7. The locking element 11 is engaged in the locking recess 12 of the device 5. The locking recess 12 can be, for example, a groove on the inner wall of the device 5. Importantly, by engaging the locking element 11 in the locking recess 12, rotation of the fixing element 7 and the handle 6 fixedly connected thereto in the circumferential direction u can be prevented. To fix the fixing element 7 regarding rotation relative to the handle 6 in the circumferential direction u, the fixing element 7 is as follows: Figure 6 The figure shows two raised anti-torsion devices 20, which point radially outward on the outer wall of the fixing element 7. The anti-torsion devices 20 are respectively fitted into grooves 21 constructed on the inner wall of the handle 6 (see, for example, [reference needed]). Figure 8In this groove, the longitudinal extension is oriented parallel to the cylindrical axis of the fixing element 7, thus allowing the handle 6 to move axially relative to the fixing element 7, i.e., to move against the restoring force of the spring element 8. This movement is necessary to eliminate the frictional fit between the device 5 and the handle 6 and to allow the fixing element 7 and the handle 6 to rotate relative to the device 5. To determine the defined rotational position of the handle 6 relative to the device 5, the outer wall of the handle 6 is as follows: Figure 13 The device shown has positioning elements 30, which are spaced 180 degrees apart from each other circumferentially u, i.e., opposite each other about the axis of the column. Correspondingly, the inner wall of the device 5 has... Figure 9 The positioning element stops 22 shown are also opposite to the column axis of the device 5. Furthermore, the rotation of the handle 6 in the circumferential direction u is also secured by the locking element 11.

[0038] Figure 2 and Figure 3 The handle cover 23 of the handle 4 is also shown, in which the actuating element 13 for operating the locking element 11, i.e., the button here, is embedded. In the shown position, the actuating surface of the actuating element 13 is flush with the outer wall 14 of the handle cover 23. When the actuating element 13 is pressed down, contact occurs with the locking element 11, and the locking element 11 pivots against the restoring force of the spring element 18 until the adapted locking sub-region 31 of the pivoted locking element 11 strikes the end stop 24. The end stop 24 and the locking sub-region 31 here define a pivot angle of, for example, approximately 20 degrees, for the locking element 11. The spring element 18 is supported on the pivot axis 25 and at one end is supported on the abutment region 26 of the fixing element 7. The restoring force of the spring element 18 holds the locking element 11 in place. Figure 2 In the locked position shown, the pivoting of the handle 4 relative to the device housing 2 of the surface processing device 1 cannot be easily achieved.

[0039] Figure 4 and Figure 5 Showing in locked state ( Figure 4 During and unlocked status Figure 5 During the process, joint 3. In the locked pivot position of the fixing element 7, the spring element 8 presses the handle 6 against the protrusion of the device 5 in the axial direction a. The fixing element 7 holds the spring element 8 and the protrusion 17, which serves as a corresponding retainer. In order to reach Figure 5In the unlocked position shown, the user presses the operating element 13 a few millimeters toward the fixed element 7, causing the locking element 11 to pivot out of the locking recess 12 against the restoring force of the spring element 18. At this time, the locking sub-region 31 of the locking element 11 reaches the end stop 24 of the fixed element 7. By simultaneously pulling and rotating the handle 4, the user can then remove the handle 6 from the fixed position. After a defined pivoting motion, for example, a 180-degree rotation in the circumferential direction u, the locking element 11 engages in the opposite locking recess 12 of the device 5 and is pressed back into the locking position by the restoring force of the spring element 18. Under overload conditions in the circumferential direction u of the joint 3, the locking element 11 is subjected to significant shear stress. Therefore, it is advantageous to equip the locking element 11 with an exit ramp if necessary. Once the limit of the force is exceeded, these release ramps can slide out of the locking recess 12 of the device 5. Because there is no form fit between the locking element 11 and the locking recess 12 in this case but a sliding ramp, the mutual contact contours can be prevented from being destroyed.

[0040] Figures 6 to 8 The individual fixing element 7 is shown in detail in perspective view. Figure 6 ), and a fixing element 7 having arranged spring elements 8 ( Figure 7 ) and a fixing element 7 having a spring element 8 and a locking element 11. Figure 8 The fixing element 7 has a support 19 on its upper end side for the pivot shaft 25 of the locking element 11. In addition to the end stop 24 of the locking sub-region 31 for the locking element 11, the fixing element 7 also has a locking stop 27 that contacts the locking element 11 as an end stop when fully pivoted into the locking recess 12 of the device 5. Furthermore, the fixing element 7 has a cable channel 28 in the center for guiding the cable passing through the joint 3. The pivoting movement of the locking element 11 is also stabilized by a guide profile 29 of the fixing element 7, which is adjacent to the locking element 11 from two longitudinal sides and prevents the locking element 11 from tilting in the locking recess 12 of the device 5 under shear force along the circumferential direction u.

[0041] Figure 9 and Figure 10 A top view of the device 5 is shown in perspective. For example, a protrusion 17 can be seen, which is designed as annular on the inner wall of the device 5 and serves to abut against the stop 9 of the fixing element 7 on one side and against the stop 10 of the handle 6 on the other. On the end side opposite to the protrusion 17, the device 5 also has a positioning element 30 for fixing the element 7 (see...). Figure 13Positioning element stops 22, which serve as rotation stops for the defined end positions of the handle 6 of the fixed element 7 or the handle 6 that is nonmovably connected to it, at circumferential intervals of 180 degrees.

[0042] Figure 11 A control element 13 with a control profile 32 is shown, which fits into a suitable area at the pivot axis 25 of the locking element 11.

[0043] at last, Figure 12 and Figure 13 The view shown is of handle 6, which has a groove 21 for an anti-torsion device 20 for securing element 7 and a positioning element 30 that points radially outward toward device 5, the positioning element being fitted into a matching positioning element stop 22 of device 5.

[0044] Figures 14 to 16 Another exemplary embodiment of the joint 3 with fixing element 7 is shown. Figure 14 First, a perspective view of a sub-region of the surface processing device 1, featuring a handle 4 pivotable around a joint 3, is shown. (As better...) Figure 15 and Figure 16 As can be seen, joint 3 has a device part 5 and a handle part 6 that can be fixed relative to each other by a fixing element 7. For this purpose, the fixing element 7 is connected to the handle part 6 in a rotation-resistant manner, but can be as described above regarding... Figures 1 to 13 As described in detail in the embodiment, it is moved relative to the handle 6 in the axial direction a. For this purpose, the fixing element 7 is clamped to the handle 6 by a spring element 8. The cylindrical fixing element 7 has opposing stops 9 on its end sides, between which a radially inwardly pointing stop 10 of the handle 6 is fitted on one side and a protrusion 17 of the device 5 is fitted on the other side. The protrusion 17 of the device 5 is supported on the stops 9 of the fixing element 7. The spring element 8 is also designed as a helical spring, which surrounds the cylindrical fixing element 7 in both the circumferential direction u and the axial direction a. The handle 6 and the device 5 are fixed to each other by the spring element 8 and the fixing element 7, such that the restoring force of the spring element 8 and the friction between the device 5 and the handle 6 prevent relative movement in both the circumferential direction u and the axial direction a.

[0045] The locking element 11, associated with the fixing element 7, has two locking sub-elements facing each other in the radial direction r. These two locking sub-elements are movably connected to each other in the radial direction r by a connector 34. Here, the locking sub-elements are connected to each other by two spring elements 33, which are designed, for example, as helical springs, and their restoring force acts, for example, inward in the radial direction r, i.e., their restoring force attempts to reduce the distance between the two facing locking sub-elements. Figure 15The actuating element 13, shown in more detail, has an actuating profile 32 that interacts with the locking element 11 when the actuating element 13 is pressed down. In the locked position of the locking element 11, the actuating profile 32 of the actuating element 13 engages between the two locking sub-elements and pushes them outward from each other. By pressing and thus lowering the actuating element 13, the locking sub-elements are released and move toward each other in the radial direction r according to the restoring force of the spring element 33, and are thus removed from the fitting locking recesses 12 of the device 5 and the handle 6. The connecting member 34 between the locking elements 11 is thus shortened, so that the locking elements 11 are no longer engaged in the locking recesses 12 and the fixing element 7 can rotate in the circumferential direction u. By rotating the handle 6, the fixing element 7, which is anti-rotatedly connected thereto, along with the locking elements 11, rotates within the device 5 until it reaches the next end position, which is also marked by the locking recesses 12 within the device 5 and the handle 6. Subsequently, the locking sub-element of the locking element 11 can move outward in the radial direction r according to the restoring force of the spring element 33, that is, move into the locking recess 12 and prevent the movement of the joint 3. Furthermore, the pivoting of the operating and handle 6 relative to the device 5 is performed as described above with respect to the first embodiment. This also applies in particular to the rotation stops of the defined end positions of the fixed element 7 or the handle 6 connected thereto, spaced 180 degrees apart circumferentially from each other.
