[0004] This document addresses the technical problem of providing a holding device for a suction device on which the different parts of the suction device, in particular the suction unit and one or more accessories, can be arranged in an efficient, flexible and stable manner.

[0005] The object is achieved by the subject matter of the independent patent claim. Advantageous embodiments are defined in particular in the dependent patent claims, described in the following description, or illustrated in the accompanying drawings.

[0006] According to one aspect, a holding device for a suction device, in particular for a cordless and / or hand-held (handheld) vacuum cleaner, is described. The suction device comprises a (cordless and / or hand-held) suction unit, to which an accessory from a number of different accessories can be attached. The suction unit is typically designed to be used alone (without an accessory) as a suction device. The different accessories can be designed for different applications. Example accessories are: a suction tube, a floor nozzle, a nozzle with a brush roller, a nozzle without a brush roller, a crevice nozzle, an upholstery nozzle, etc. The individual accessories can typically each be connected to the suction unit via a coupling.

[0007] The holding device comprises a base unit that is designed to be (directly) attached to a wall and that is designed to accommodate the suction unit. The base unit can, for example, have one or more holes, in particular bores, on a rear side, through each of which a screw can be passed in order to (directly) attach the base unit to a wall (in particular to be screwed to a wall). The base unit can preferably be attached so high that the (in particular all) parts of the suction device held by the holding device float above the floor (and are thus completely held by the holding device).

[0008] The base unit is preferably designed such that the suction unit of the suction device can be placed on the base unit along a transverse axis (and then held by the base unit). It can be provided that the base unit is attached to the wall of a room such that the transverse axis runs substantially perpendicular to the floor of the room.

[0009] The base unit can further be configured to charge the electrical energy storage device of the suction unit when the suction unit is arranged in the base unit. For this purpose, the base unit can be configured to be electrically connected to an electrical power supply network.

[0010] The holding device further comprises a rail for holding or retaining one or more accessories, wherein the rail is designed to be displaceably attached to the base unit. The rail can, in particular, be designed to be displaced relative to the base unit along a longitudinal axis that runs transversely to the transverse axis. It can be provided that the longitudinal axis runs parallel to the floor of the room in which the holding device is arranged.

[0011] The holding device is preferably designed such that the holding device is and / or can be attached to a wall solely via the base unit, and in particular not via the rail. Alternatively or additionally, the holding device is preferably designed such that the rail and one or more (in particular all) accessories attached to the rail are held (on a wall), in particular solely, by the base unit and, in particular exclusively, attached to a wall via the base unit.

[0012] Thus, a holding device is described that enables efficient, flexible, and stable storage of the various parts of a suction device. In particular, by providing a movable rail, the holding device enables flexible storage for left- and / or right-handed users.

[0013] The holding device can comprise at least one holding unit, which is designed to be attached to the rail and which is designed to hold one or more, in particular exactly two, accessories. The holding unit is preferably designed to be displaced along the rail. The holding unit can, in particular, be designed to be attached, in particular locked, at a plurality of different positions along the rail.

[0014] The rail can, for example, have a spring element (for a tongue and groove connection) on each of two opposite edges, running along the longitudinal axis of the rail. The holding unit can have guide elements designed to engage around the spring elements arranged on the opposite edges of the rail, so that the holding unit is attached to the rail so that it can be moved along the longitudinal axis. This enables particularly stable and flexible storage of one or more accessories on the rail.

[0015] The holding unit can have a (e.g., tubular) support element that extends along the transverse axis from a first (e.g., upper) end to a second (e.g., lower) end. The holding unit can be configured to receive a first accessory at the first end of the support element and a second accessory at the second end of the support element. Furthermore, the support element can have a fastening element, e.g., a locking element, at one or both ends, with which an accessory can be fastened to the respective end, such that the respective accessory is stably and releasably fastened to the holding unit.

[0016] The base unit can have a recess on the rear side facing the wall for receiving the rail, wherein the recess is preferably designed as a guide (along the longitudinal axis) for the rail. The rail can then be designed to be particularly stable and movable within the recess of the base unit.

[0017] The rail has a first end along the longitudinal axis and an opposite second end. The rail can have a length of 10 cm or more, in particular 15 cm or more, between the two ends. The rail can preferably be attached to the base unit so that it can be displaced along the longitudinal axis in such a way that a plurality of different points on the rail, in particular any point on the rail, can be placed between the first end and the second end of the rail on the base unit. The rail can in particular be designed such that the rail can be connected to the guide of the base unit from the first end. The rail can then be pushed further along the longitudinal axis through the guide of the base unit until the second end of the rail is arranged on the base unit. This enables a particularly flexible arrangement of the rail on the base unit.

[0018] The rail can have a stop at each of the first and / or second ends, particularly in the form of an end cap at the respective end, so that the rail cannot be displaced beyond the stop and thus detached from the base unit. This allows for a particularly secure attachment of the rail to the base unit.

[0019] The holding device is preferably designed such that the rail can be locked to the base unit at a plurality of different locations, in particular at any location along the longitudinal axis of the rail (so that the rail can no longer be moved). The locking mechanism is preferably designed to be releasable, so that the configuration of the holding device can be changed efficiently and flexibly.

[0020] The rail can, for example, have a groove running along the longitudinal axis of the rail, and the holding device can have a slot nut configured to be moved within the groove of the rail. The slot nut can have at least one threaded bore, and the base unit can have at least one hole on the rear side facing the wall.

[0021] The holding device can have at least one slot-block screw that can be guided through the hole in the rear of the base unit and screwed into the threaded hole of the slot-block, so that the rail is attached to the base unit so that it can be moved along its longitudinal axis. Tightening the slot-block screw can also lock the rail to the base unit at a location, in particular at any location, along its longitudinal axis. This allows a movable rail to be provided in a particularly efficient and stable manner.

[0022] The rail can optionally be designed to be mounted to a wall separately from the base unit (so that the rail and base unit do not touch), particularly via one or more holes in the rail. This can further increase the flexibility of storing the parts of a suction device.

[0023] According to a further aspect, a system is described that comprises a suction device, in particular a vacuum cleaner, with a (hand-held) suction unit and one or more accessories. Furthermore, the system comprises a holding device for the suction device, wherein the holding device is designed as described in this document.

[0024] It should be noted that any aspects of the holding device and the system described in this document can be combined in a variety of ways. In particular, the features of the patent claims can be combined in a variety of ways.

[0025] The invention will be described in more detail below with reference to exemplary embodiments illustrated in the accompanying drawings. Figure 1 shows a vacuum cleaner with a suction unit, a suction tube, and a nozzle (as an example of a suction device); Figures 2a to 2d show different views of a holding device for a vacuum cleaner; Figures 3a to 3c show different views of a system with a holding device and with parts of a vacuum cleaner attached thereto; and Figure 4 shows a separate arrangement of the rail and the base unit of a holding device.

[0026] As stated at the beginning, this document deals with the storage of the various parts of a vacuum cleaner in a compact, flexible, and stable manner. In this context, Fig. 1 an exemplary (handheld) vacuum cleaner 110 having a suction unit 110 with an electrical energy storage device 111. An accessory 120, 130 can be connected to the suction unit 110 via a coupling 121. In the example shown, the suction unit 110 is connected via a coupling 121 to a suction tube 120, which in turn is connected via a coupling 121 to a floor nozzle 130.

[0027] The Figuren 2a bis 2d show different views of a holding device 200 for a vacuum cleaner 100. The holding device 200 has a base unit 230 which is designed to be attached to a wall 240. As exemplified in Fig. 2d For this purpose, as shown, the base unit 230 may have one or more fastening holes 254 through which a screw 253 may be passed to fasten the base unit 230 to a wall 240.

[0028] The base unit 230 can have a first component 250 that can be attached to a wall 240. Furthermore, the base unit 230 can have a second component 260 that can be connected to the first component 250, in particular such that the one or more screws 253 are concealed by the second component 260. The second component 260 can, for example, be designed to be pushed onto the first component 250. The second component 260 can also be designed to be firmly (and optionally releasably) connected to the first component 250 via a snap-in connection.

[0029] The base unit 230 can be designed to support the (relatively heavy) suction unit 110 of a vacuum cleaner 100. For this purpose, the base unit 230, in particular the second component 260 of the base unit 230, can have a shape that is complementary to the shape of a portion of the suction unit 110, such that the suction unit 110 can be attached to the base unit 230 in a compact and stable manner and can be supported by the base unit 230. The base unit 230 is preferably designed such that the suction unit 110 can be inserted into the base unit 230 from one side, in particular from above. Furthermore, the base unit 230 can be designed such that an accessory part 120, 130 of the vacuum cleaner 100 can be attached to the opposite side, in particular on the lower side, of the base unit 230 and held by the base unit 230.For this purpose, a coupling 121 can be arranged on the base unit 230, to which an accessory part 120, 130 can be connected.

[0030] The base unit 230, in particular the first component 250 of the base unit 230, is designed such that a rail 210 can be fastened to the base unit 230, in particular to the first component 250 of the base unit 230, on which rail one or more holding units 220 can be arranged, wherein the individual holding units 220 are each designed to support one or more accessories 120, 130 of the vacuum cleaner 100. The rail 210 is preferably arranged on the base unit 230, in particular on the first component 250 of the base unit 230, in such a way that the rail 210 can be displaced relative to the base unit 230 (in particular in the horizontal direction and / or along a longitudinal axis of the rail 210). This makes it possible to place the base unit 230 at either end 212 of the rail 210 or at any location between the two ends 212 of the rail 210.

[0031] The base unit 230, in particular the first component 250 of the base unit 230, can have a recess 252 on the rear side facing the wall 240, in which the rail 210 can be arranged. The rear side of the base unit 230, in particular of the first component 250 of the base unit 230, can have, for example, one or more horizontally extending grooves within the recess 252, into which the rail 210, in particular into the one or more spring elements 214 of the rail 210, can be inserted from the side in order to fix the rail 210 to the base unit 230.

[0032] The mechanical connection between the base unit 230 and the rail 210 is preferably configured such that the rail 210 (and accessories 120, 130 attached thereto) is held in any arrangement of the rail 210 relative to the base unit 230. In particular, the mechanical connection between the base unit 230 and the rail 210 is preferably designed for the loading case in which the base unit 230 is arranged at one end 212 of the rail 210.

[0033] The rail 210 can have a groove 211 along the longitudinal axis of the rail 210 (i.e., along the horizontal direction). Furthermore, the base unit 230, in particular the first component 250 of the base unit 230, can have one or more sliding blocks 251 on the rear side, which can be pushed (from one end 212 of the rail 210) into the groove 211 of the rail 210 in order to connect the rail 210 and the base unit 230, in particular the first component 250 of the base unit 230. The one or more sliding blocks 251 can each be fixed within the groove 211 of the rail 210 using a sliding block screw 255. In this way, the rail 210 can be fixed and / or locked relative to the base unit 230 in an efficient and stable manner. Furthermore, a relative movement between the rail 210 and the base unit 230 can be reliably avoided (after fixation).

[0034] The base unit 230 also typically has a charging interface (not shown) which is electrically connected to a corresponding charging interface of the suction unit 110 when the suction unit 110 is arranged in the base unit 230, and via which the electrical energy storage device 111 of the suction unit 110 can be charged.

[0035] The rail 220 is designed such that one or more holding units 220 can be arranged and / or fastened to the rail 220. A holding unit 220 can be moved as desired along the rail 220, ie in the horizontal direction, as indicated by the double arrows in Fig. 2a For this purpose, a holding unit 220 can have one or more guide elements 221, wherein a guide element 221 is designed to engage around a corresponding spring element 214 of the rail 210.

[0036] In particular, a guide element 221 can form a groove running along the longitudinal axis of the rail 210, into which a corresponding spring element 214 of the rail 210 can be arranged. Fig. 2c In the example shown, the rail 210 has an upper spring element 214 and a lower spring element 214, wherein the two spring elements 214 are arranged on the side of a support 215 of the rail 210 facing away from the wall 240 (so that the two spring elements 214 and the support 215 form a T-shape or H-shape). Correspondingly, a holding unit 220 has an upper guide element 221 for the upper spring element 214 and a lower guide element 221 for the lower spring element 214. In this way, a holding unit 220 can be pushed onto the rail 210 in a comfortable and stable manner from one end 212 of the rail 210 and held by the rail 210.

[0037] Optionally, a holding unit 220 can have a fixing element (not shown) with which the holding unit 220 can be fixed at a desired position along the longitudinal axis of the rail 210. The fixing element can, for example, comprise a wear block that can be moved within the groove 211 of the rail 210 and fixed (e.g., using a wear block screw).

[0038] A holding unit 220 can be configured to support one or more accessories 120, 130 of the vacuum cleaner 100. For this purpose, the holding unit 220 can have a support element 226, which is, for example, tubular. The support element 226 is preferably configured such that at least one accessory 120, 130 can be plugged onto the support element 226 and then carried by the holding unit 220. The Fig. 2c The support element 226 shown is designed such that an accessory part 120, 130 can be attached to the upper side of the support element 226 and to the lower side of the support element 226. The support element 226 can have a coupling 121 or a locking element 227 at one or both ends, via which a fixed, detachable connection can be established between the support element 226 and an accessory part 120, 130, so that the accessory part 120, 130 is held stably by the holding unit 220.

[0039] Figuren 3a bis 3c show different views of a system 300 comprising a holding device 200 and a vacuum cleaner 100 with one or more accessories 120, 130, 330, e.g., a suction tube 120, one or more floor nozzles 130, and / or one or more special nozzles 330. The figures illustrate how the rail 210 of the holding device 200 can be flexibly positioned relative to the base unit 230 of the holding device 200.

[0040] The holding device 200 can be designed as shown for example in Fig. 4 It is shown that the rail 210 and the base unit 230 can be fastened separately from one another at different positions on a wall 240 or on different walls 240. For this purpose, the rail 210 can, for example, have one or more holes 411, which are each arranged within the groove 111 of the rail 210, and via which the rail 210 can be fastened directly to a wall 240 using one or more screws. This further increases the flexibility of arranging parts of a vacuum cleaner 100 on the holding device 200.

[0041] A wall mount 200 for a cordless vacuum cleaner 100 is thus described, which is designed to accommodate at least one accessory 120, 130, 330 (optionally directly on the base unit 230) in addition to the suction unit 110, and which has an expansion option (e.g. using the rail 210 and one or more holding units 220) for at least one standard accessory 120, 130 and one or more additional small accessories 330.

[0042] The described holding device 200 can be considered, in particular, as a combination of a wall charging station or base station (i.e., a base unit 230) for a cordless vacuum cleaner 100 and an adaptive rail 210 with one or more movable and removable accessory adapters (i.e., holding units 220) for storing one or more accessories 120, 130, 330. The base station 230 can, if necessary, be mounted to a wall 240 using two screws 253. The rail 210 can be slidably attached to the base station 230.

[0043] The position of the rail 210 can be individually adjusted depending on the available space and the number of accessories 120, 130, 330. The rail 210 can be fixed to the base station 230 using a slot nut 251 and one or more slot nut screws 255, so that no additional drilling in the wall 240 is required. If necessary, the rail 210 can be screwed directly to the wall 240 (as shown in the example in Fig. 4 shown).

[0044] The individual accessory adapters (i.e., holding units 220) can be moved along the rail 210, thus enabling the insertion of accessories 120, 130, 330 of different sizes. Two accessories 120, 130, 330 can preferably be arranged on each individual accessory adapter (i.e., holding units 220). The individual adapters (i.e., holding units 220) can be designed such that the adapters (i.e., holding units 220), together with the one or more accessories 120, 130, 330, can be completely removed from the rail 210. The rail 210 can be designed such that any rail end caps 216 at the ends 212 of the rail 210 do not need to be removed for this purpose.

[0045] In other words, a holder 230, in particular a base unit, for a handheld vacuum cleaner 100 is described, to which one or more rails 210 for holding accessories 120, 130, 330 can be fastened, wherein on the one hand the one or more rails 210 are movably fastened to the holder 230, and the accessories 120, 130, 330 are fastened to the one or more rails 210 via movable fastening elements 220 (ie holding units).

[0046] The base station 230 (i.e., the base unit) can be permanently mounted on a wall 240. A slide-in rail 210 can be moved relative to the base station 230. One or more accessory holders 220 (i.e., holding units) can be movably arranged on the rail 210 itself. This makes it possible to expand a base station 230 (possibly subsequently) with a rail 210. Furthermore, it is possible to arrange accessories 120, 130, 330 advantageously for left- or right-handed users.

[0047] Thus, a base station 230 is described with a fastening option for attaching the base station 230 to a wall 240. The base station 230 has a receptacle for a handheld cordless vacuum cleaner (i.e., in particular, for the suction unit 110 of a cordless vacuum cleaner). The rear of the base station 230 has a receptacle 252 for at least one accessory rail 210, wherein the rail 210 is arranged to be displaceable relative to the fixed base station 250. As a result, the holding device 200 is attached to a wall 240 only via the base station 230 (and not via the rail 210).

[0048] The one or more accessory carriers (i.e., holding units 220) are preferably displaceable relative to the base station 230 (on the rail 210). The rail 210 can optionally have a stop (e.g., in the form of an end flap 216) at at least one end 212, so that the rail 210 cannot be pushed out of the recess 252 of the base station 230 (without the stop being removed). Alternatively or additionally, the rail 210 can be designed to be locked to the base station 230. Alternatively or additionally, an accessory holder (i.e., a holding unit 220) can be designed to be locked to the rail 210. Alternatively or additionally, the rail 210 can be designed to be guided relative to the base station 230 by a sliding block 252 and, if necessary, to be locked at any desired location relative to the base station 230.

[0049] The present invention is not limited to the embodiments shown. In particular, it should be noted that the description and figures are intended only to illustrate the principle of the holding device 200 and / or the system 300. List of reference symbols
