Description

[0001] The present invention relates to a suction cleaning attachment of a cleaning device for use in cleaning the interior of motor vehicles by means of a suction air flow. Furthermore, the present invention also relates to a stationary cleaning device for use in cleaning the interior of motor vehicles, comprising a suction cleaning attachment of the type according to the invention. The suction cleaning attachment is intended to be inserted and held in a holder of the cleaning device when not in use. Ultimately, the suction cleaning attachment can be removed from the holder for cleaning the interior of motor vehicles. Finally, the present invention also relates to the use of the suction cleaning attachment in a stationary cleaning device for cleaning the interior of motor vehicles and to the use of the stationary cleaning device for cleaning the interior of motor vehicles by means of the suction flow.

[0002] Stationary cleaning devices of the aforementioned type are also referred to as self-service or self-service vacuum cleaner systems, which are typically used in commercial areas, i.e., in gas stations, car washes, workshops, and the like. A characteristic of a stationary cleaning device is a central or stationary vacuum cleaner system or operating unit, which has the technical components necessary for operating the cleaning device, such as a blower device for generating negative pressure and, if necessary, control and / or regulating devices or electronic components. The central vacuum cleaner system or operating unit is "stationary," meaning it is essentially immobile or stationary during its operating period, arranged on a surface or property. Due to its "stationary design," no relocation or movement of the vacuum cleaner system or operating unit is possible for the majority of its operating period.Operating unit and / or blower device, with the exception of the hand-operated suction cleaning attachment, is positioned relative to the substrate.

[0003] The central vacuum cleaner system or operating unit is assigned at least one suction station or extraction point, preferably a plurality of suction stations or extraction points, for example in a car wash or a commercially used cleaning facility for cleaning the interior of vehicles in assigned suction stations or extraction points. The supply of the suction stations or

[0004] The suction air is supplied centrally to the stationary vacuum system or operating unit. Each vacuuming point is assigned a vacuum cleaning attachment, which is connected to the central vacuum system or operating unit via a hose. Dirt and / or particles can then be vacuumed from the vehicle interior via the vacuum cleaning attachment or vacuum nozzle. The vacuum cleaning attachment is usually designed to vacuum up dirt and / or particles from a surface, such as the seats and / or floor mats.

[0005] Vacuum cleaning attachments of the type in question comprise a housing with an internal suction channel for guiding the suction air flow. The housing has a handle with a gripping area and a housing nozzle with a suction opening at the end of the suction channel. This allows for the targeted and effective removal of dirt from the vehicle interior.

[0006] Against this background, stationary cleaning devices of the type described above are to be understood in contrast to mobile cleaning devices in the household sector, such as handheld vacuum cleaners, corded vacuum cleaners, robot vacuum cleaners, or small vacuum cleaners, which are operated as self-sufficient or compact cleaning units close to the body or mobile, i.e., mobile or tethered to the user. Corded vacuum cleaners typically have a movable operating unit on casters, whereas handheld vacuum cleaners or small vacuum cleaners are self-sufficient or independent vacuum units that are carried and operated by the user.

[0007] In practice, the use of stationary cleaning devices creates problems when cleaning the interior of motor vehicles. Many areas in the vehicle interior are either inaccessible or difficult to access, meaning that these areas cannot be cleaned at all or only inadequately. This applies, for example, to the area between the car seats, but also to areas that are narrow or difficult to access. Accordingly, efficient extraction of dirt particles in these areas is either impossible or very difficult. Furthermore, these narrow or difficult-to-access areas are often difficult to see, meaning that any dirt present in these areas is not even detected.

[0008] In practice, portable handheld or canister vacuum cleaners used in the home are known to have a floor nozzle with a light source on the front, so that the area in front of the nozzle is illuminated when the nozzle is moved across the floor. However, such illumination is only useful for cleaning flat floors in the home, but is not compatible with the intended use of cleaning motor vehicles and the aforementioned awkward or difficult-to-access areas in vehicle interiors.

[0009] In the case of vacuum cleaning attachments of the type mentioned above, it is also known to arrange a lighting device with a lamp inside the housing or in the suction duct. The power supply for the lamp is via a cable from the central or stationary vacuum cleaner system or operating unit. The disadvantage of this approach, however, is that the arrangement of the lamps inside the suction duct results in a high degree of soiling of the lamps. The cable-based power supply via the central vacuum cleaner system is also prone to errors and requires maintenance. The vacuum cleaning attachments must also be extensively modified to fit the lamps in the suction duct and to connect the power to the central vacuum cleaner system, which is time-consuming and costly. Furthermore, if the lamp is arranged inside the housing orThere is no longer any illumination of the suction area in the suction channel as soon as the suction opening is attached or the suction opening is inserted into particularly narrow areas.

[0010] US 6 792 645 B2 relates to a cleaning tool for a vacuum cleaner hose according to the preamble of independent claim 1. US 10 849 475 B1 relates to a vacuum cleaner attachment having a telescopic brush head on a semi-flexibly mounted base.

[0011] US 10 238 255 B2 relates to a vacuum accessory tool comprising a nozzle body with a first end and a second, spaced end and at least one density-emitting element.

[0012] US 2021 / 212532 A1 relates to a suction cleaning attachment of a cleaning device which is intended to be inserted and held in a holder when not in use.

[0013] The object of the present invention is to avoid the aforementioned disadvantages of the prior art or at least to substantially reduce them. In particular, the object of the present invention is to provide a vacuum cleaning attachment that enables user-friendly, improved, and efficient interior cleaning of motor vehicles.

[0014] The above-mentioned object is achieved according to the invention at least essentially in that the illuminant, which is directed at least partially, preferably essentially, in the direction of the suction opening, is arranged on the outside of the housing and in that the lighting device has at least one, in particular rechargeable, accumulator or an electrical storage device for electrically supplying the illuminant.

[0015] In other words, when the vacuum cleaning attachment is in use, the light source is exposed on the outside of the housing or is arranged outside the suction channel and is preferably firmly connected to the housing, preferably to the housing nozzle. By directing the light source or the light beams emitted by the light source in the direction of the suction opening, targeted and purposeful illumination of areas to be cleaned, in particular those that are difficult to access, is possible. The illumination of the areas to be cleaned is thus positively coupled to the suction opening, so that the areas illuminated by the light source are always coupled with the movement or orientation of the suction opening. The suction opening or the light source can thus be specifically directed at hard-to-reach areas, illuminating these areas while simultaneously cleaning them with the suction air flow.This significantly increases the cleaning efficiency of the cleaning device compared to the state of the art, as dirt in hard-to-reach or poorly lit areas can be registered and removed accordingly.

[0016] Due to its external placement on the housing, the lamp is designed independently of the suction channel or connected to the vacuum cleaning attachment. Connecting the lamp to the outside of the housing is very simple to implement.

[0017] In addition to arranging the illuminant on the exterior of the housing, the invention also provides for the lighting device to have at least one, in particular rechargeable, accumulator for electrically supplying the illuminant. Accordingly, the power supply to the illuminant is ensured by the vacuum cleaning attachment itself or by the accumulator connected to it, and is thus decoupled or independent of a central vacuum cleaner system or operating unit of the stationary cleaning device connected to the vacuum device attachment. An external power supply via a supply device connected to the vacuum cleaning attachment, for example, via the central or stationary vacuum cleaner system or the central operating unit, is thus unnecessary.

[0018] In this respect, the lighting device designed according to the invention can be flexibly and efficiently connected to existing vacuum cleaning attachments without the need for complex adaptations to the vacuum cleaning attachment itself or to other components of the stationary cleaning device. This has proven particularly advantageous in the commercial environment of car washes or large gas stations, where a large number of suction or extraction points are provided.

[0019] Preferably, the lighting device is arranged as a structural unit or the illuminant and the accumulator are arranged as a technically combined group on the outside of the housing, in particular the housing socket.

[0020] According to the invention, the lighting device has at least one lighting unit on the outside of the housing, preferably on the housing neck, which can be detached at least partially from the housing or is designed as a separate lighting unit which can be separated from the housing, preferably from the housing neck, in particular wherein the lighting unit comprises the accumulator, the lighting means and, particularly preferably, at least one circuit board electrically connected to the accumulator and / or to the lighting means.

[0021] Connecting the lighting device to the outside of the housing, preferably the housing socket, is structurally simple to implement, especially compared to the conventional solution in which the light source is connected inside the intake duct. Due to the free accessibility on the outside of the housing or the housing socket, installation is significantly simplified.

[0022] In other words, the lighting unit is arranged on the outside of the housing in a detachable and / or separately replaceable manner. In particular, the lighting device has a lighting unit that is completely detachable from the housing. The components of the lighting unit, preferably the battery and / or the illuminant and / or the circuit board, can be separated from one another or detached separately from the housing, preferably from the housing socket, for example in a form-fitting and / or force-fitting manner, in particular by screwing and / or locking. This enables the respective component of the lighting unit to be replaced as needed, for example for maintenance and / or repair purposes. This ensures reliable operation of the vacuum cleaning attachment according to the invention.

[0023] As an alternative to the separate removal of the components of the lighting unit, however, it can also be provided that the lighting unit is designed as a separate, self-contained unit that can be removed from the housing, preferably from the housing socket. In this embodiment, the components of the lighting unit, preferably the accumulator, the illuminant, and, particularly preferably, the circuit board, are combined as a separate or self-contained interchangeable unit in a common or compact housing or base body.

[0024] The lighting unit can then be removed from the vacuum cleaning attachment or the housing, preferably from the housing nozzle, as a reusable or self-sufficient unit, for example to charge the battery, and connected to a corresponding charging station.

[0025] In particular, a sufficient number of lighting units with charged batteries can be kept on hand at all times, which can be connected to the corresponding vacuum cleaning attachments as needed. Especially in industrial operations, this ensures that a sufficient number of operational vacuum cleaning attachments with charged batteries are always available. Furthermore, the design of the lighting system as a separately removable lighting unit simplifies the maintenance and operation of the stationary cleaning device.

[0026] Preferably, the lighting device or lighting unit has a cover that can be releasably connected to the housing, preferably to the housing socket, for covering the accumulator and / or the illuminant and / or the circuit board. This allows the illuminant and / or the accumulator and / or the circuit board to be easily accessible for maintenance and / or repair purposes as needed. The releasable connection of the cover to the housing can be implemented in a variety of ways known to those skilled in the art, for example, by snap-on and / or screw connections.

[0027] Particularly preferably, the lighting device has a circuit and / or is designed such that the light source remains permanently illuminated during the use of the vacuum cleaning attachment. This allows for easy handling and ensures that the areas or surfaces to be cleaned are adequately illuminated throughout the entire period of use or during the entire vacuuming process. However, it is also possible for the light source to be switched on or off by the user as needed during the use or in-use state.

[0028] The intended use state is during interior cleaning of the vehicle, in which the vacuum cleaning attachment is held by the user on the outside of the housing by the handle area and is guided by hand, with the suction opening leading, to clean the interior of the vehicle. The automatic and continuous activation or illumination of the lamp simplifies handling, while any switching devices for manually deactivating or activating the lamp are also eliminated, which contributes to the simple design of the vacuum cleaning attachment.

[0029] The lighting device can have at least two contacts for electrical interaction with mating contacts of the holder, preferably wherein the contacts are arranged on the outside and in particular on the top of the lighting device. Accordingly, the contacts are arranged or exposed in an accessible manner on the outside or top, so that when not in use, the contacts of the vacuum cleaning attachment are connected to the corresponding mating contacts of the holder, and the battery is charged when the vacuum cleaning attachment is not in use.

[0030] The non-use state is therefore intended before and after the interior cleaning of the motor vehicle. In particular, the vacuum cleaning attachment is arranged in the holder of the stationary cleaning device when not in use. The holder preferably has the corresponding mating contacts on the inside for electrical contact with the contacts, so that the battery is charged when not in use or when the vacuum cleaning attachment is in a charging state.

[0031] This ensures efficient charging of the battery and thus reliable illumination during use, since the time outside of the cleaning period, i.e. during non-use, is used specifically and efficiently to charge the battery.

[0032] In particular, in this context, it is provided that at least one recess is provided on the top side of the lid, starting from a contact and extending in the direction of the suction opening, preferably over the entire top side of the lid and / or in the direction of the suction opening to the end of the lid. The recess is provided in particular for engagement or for receiving an associated mating contact. This in particular ensures contact-free and frictionless interaction between the mating contact and the lid, whereby wear on the mating contact is avoided or at least reduced. This is particularly important when inserting or removing the suction cleaning attachment into or from thefrom the quiver is advantageous because the counter contact is arranged within the recess when inserted into the quiver or removed from the quiver, thus avoiding direct contact between the counter contact and the top of the lighting device or the cover.

[0033] Furthermore, at least one contact can be designed as a spring-loaded ball which at least partially projects beyond the lighting device and / or the cover. When interacting with the mating contact, the contact can be displaced into the cover or towards the suction channel against the spring force. This creates secure contact between the contact and the mating contact and ultimately efficient charging of the battery as a result of the electrical contact between the contact and the mating contact within the holder. The spring loading of the ball is preferably achieved via a contact spring or another spring-loaded means, in particular wherein the contact spring or spring means is electrically conductive. The ball is connected to the circuit board in an electrically conductive manner via the contact spring or spring means.

[0034] Particularly preferably, the accumulator is arranged between the illuminant and the contacts on the circuit board. The illuminant is preferably oriented toward the suction opening, and the contact is oriented or arranged on the circuit board opposite the illuminant, i.e., toward the handle.

[0035] In other words, the contact is held on the upper side of the lid, preferably in a form-fitting and / or force-fitting manner, by means of the spring means or the contact spring, preferably in such a way that the contact protrudes as a pressure contact in the use state of the suction cleaning attachment with respect to the upper side of the lid in a spring-loaded manner.

[0036] It has proven expedient for the lighting device to be arranged on the housing connector, in particular in the transition area between the housing connector and the handle. In this context, it is particularly preferred that the lighting device be arranged on the housing connector such that the distance between the light source and the suction opening corresponds to at least 60%, preferably at least 70%, of the distance between the suction opening and the handle and / or the handle area. As a result, the majority of the housing connector is free of the lighting device, allowing the housing connector to penetrate hard-to-reach areas more easily from the suction opening. Therefore, the external connection of the lighting device or lighting unit does not impair the accessibility or handling of the vacuum cleaning attachment.

[0037] According to a further advantageous embodiment, the housing connector has two opposing flat sides, starting from the suction opening, preferably with the flat sides merging into a circular cross-section of the suction channel at a transition area to the handle. Particularly preferably, the lighting device is arranged on at least one flat side, preferably adjacent to a transition area to the handle. The flat side structurally provides a robust and practical support surface for the lighting device, thus enabling a correspondingly secure connection of the lighting device to the housing connector in this area.

[0038] According to a particularly preferred embodiment, at least two lighting devices are provided, preferably arranged opposite one another on the housing connector, in particular on opposite flat sides of the housing connector. This illuminates the area to be cleaned or the area of the suction opening from both sides. This, in turn, improves the illumination even in particularly hard-to-reach areas, which in turn leads to a further improved cleaning result when using the suction cleaning attachment according to the invention.

[0039] The material for the housing, the housing socket, and / or the handle is preferably a plastic, in particular a thermoplastic. Polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), and / or polystyrene (PS) are particularly preferred. The aforementioned components of the vacuum cleaning attachment can, in particular, be made of the aforementioned materials. The entire vacuum cleaning attachment is preferably made of plastic. The aforementioned plastics are characterized by high strength.

[0040] In general, it should be noted that the handle is preferably arranged so as to be detachable from and / or movable relative to, and preferably rotatable relative to, the housing socket. Accordingly, the housing is preferably designed in several parts, preferably with the lighting device being arranged on the housing socket, which is arranged so as to be movable relative to, and preferably rotatable relative to, and / or detachable from, the handle. This enables the housing socket or the lighting device to be decoupled from the handle as needed for maintenance and / or repair purposes. The handle is preferably locked to the housing socket. Alternatively or additionally, the handle cannot be removed from the housing socket without causing damage, particularly after it has been locked. The handle can be rotatable relative to the housing socket, but this does not have to be possible.

[0041] Particularly preferably, the housing has a mouthpiece that is detachably arranged from the housing nozzle, wherein the mouthpiece forms the suction opening. The mouthpiece can preferably be pushed onto the end of the housing nozzle. The mouthpiece preferably forms a wearing part, since in the area of the suction opening it is usually placed on the surfaces to be cleaned during operation and is thus subjected to frictional stress. After a certain amount of wear and tear, which can preferably be indicated by a marking applied to the mouthpiece, the mouthpiece can be replaced with an unused or new mouthpiece. This allows for simple, low-maintenance and / or easy maintenance of the suction cleaning attachment without the need for complex adjustments to the housing nozzle or the lighting device connected to it.

[0042] In particular, a stop designed as a step or a stop extending beyond the handle area and / or the lighting device is provided on the outside of the housing between the suction opening and the handle area to interact with an edge of the holder. When not in use, the suction cleaning attachment rests axially against the edge of the holder. This ensures easy and safe handling and ensures reliable axial alignment between the contacts and the mating contacts.

[0043] Furthermore, the present invention also relates to a stationary cleaning device for use in cleaning the interior of motor vehicles. The cleaning device has a vacuum cleaning attachment according to at least one of the previously described embodiments. Furthermore, the stationary cleaning device comprises at least one holder for holding the vacuum cleaning attachment when not in use or when charging—that is, before or after cleaning the interior of a vehicle. Preferably, the cleaning device has a central or stationary vacuum cleaner system or operating unit with a blower device for generating a negative pressure, wherein the blower device is assigned to the suction channel via a hose (suction hose). The blower device ultimately provides the suction air flow required for cleaning the interior of vehicles, which flow is guided along the suction channel.

[0044] The stationary cleaning device preferably has a plurality of vacuum cleaning attachments, in particular more than 5, particularly preferably more than 10, in particular more than 20, vacuum cleaning attachments, preferably with each vacuum cleaning attachment being assigned a suction point or a suction location, or vice versa. In this case, the vacuum cleaning attachments are connected to the central vacuum cleaner system or central operating unit of the cleaning device via corresponding hoses. In addition, a holder is also provided for each vacuum cleaning attachment. The holders are preferably powered by the vacuum cleaner system or the central operating unit, with the vacuum cleaner system having at least one corresponding control and / or regulating device for this purpose.

[0045] In this context, it is understood that all of the aforementioned preferred embodiments and the advantages of the invention also apply equally to the stationary cleaning device according to the invention. To avoid unnecessary repetition, these explanations are omitted and explicit reference is made to the preceding explanations.

[0046] According to the invention, the cleaning device has at least one mating contact arranged in the holder and connected to a power source for electrically contacting the contact of the vacuum cleaning attachment, so that the battery is charged when the vacuum cleaning attachment is not in use, i.e., when the holder is inserted in the holder and / or when the battery is in the charging state. In the present case, the non-use state thus refers to a charging state of the battery or the vacuum cleaning attachment.

[0047] When the vacuum cleaning attachment is inserted, there is electrical contact between at least one contact, preferably both contacts, of the vacuum cleaning attachment and a corresponding mating contact, preferably both corresponding mating contacts, of the holder. As a result of the electrical contact, the battery is charged. In other words, the holder functions as a charger for the battery of the vacuum cleaning attachment.

[0048] In particular, the quiver can have a coding device which is designed so that the suction cleaning attachment can only be inserted into the quiver, in particular in a defined rotational position, in such a way that the contact electrically contacts the counter contact.

[0049] The coding device, which can also be understood and / or designed as an insertion and / or positioning device, ensures that the suction cleaning attachment can only be inserted into the holder, or that the charging state is only achieved when fully inserted into the holder, when the contacts of the suction cleaning attachment are correctly aligned with the corresponding mating contacts of the holder. Therefore, the insertion or insertion of the suction cleaning attachment into the holder is only possible when the suction cleaning attachment, in particular the housing connector, is correctly rotated relative to the holder.

[0050] The coding device preferably has a coding opening which interacts with the suction cleaning attachment, preferably with the lighting device and / or with the housing socket in such a way that it is ensured that the suction cleaning attachment or the housing socket can only be fully inserted into the quiver in such a way that contacting of the contacts with the counter contacts in the quiver is ensured when not in use or when charged.

[0051] When not in use or when charging, the contacts of the vacuum cleaning attachment, on the one hand, and the mating contacts of the holder, on the other, are arranged or aligned opposite each other. The mating contacts are preferably designed as sliding contacts and / or as elastically reversibly deformable and / or spring-like mating contacts. In conjunction with the preferably spring-loaded, spherical contacts of the vacuum cleaning attachment, this enables robust and / or secure electrical contact through the force-locking contacts on the one hand and the mating contacts on the other.

[0052] Preferably, the coding opening or insertion and / or positioning opening is at least partially delimited by two opposing, preferably flat coding surfaces or insertion and / or positioning surfaces, wherein, preferably, at least two mating contacts are arranged on one, preferably on each, coding surface or insertion and / or positioning surfaces. The coding surfaces or insertion and / or positioning surfaces interact with the lighting devices, in particular with the covers or upper sides of the lighting devices, in such a way that the suction cleaning attachment or the housing nozzle is essentially free of play and / or non-rotatably and / or transversely fixed, i.e., is held in the quiver only in the axial direction in the direction out of the quiver, when not in use or when loaded.

[0053] According to a particularly preferred embodiment, the mating contact(s) is / are recessed relative to the coding surface or insertion and / or positioning surface, for example, by at least 0.2 mm. The contacts of the lighting device can then penetrate the associated coding surface under spring load and make electrical contact with the recessed mating contacts. With this solution, the previously described recesses on the cover of the lighting device can be omitted, since the inserted mating contacts do not come into contact with the cover of the lighting device. Even with this variant with the recessed mating contacts, there is no wear on the surface of the lighting device.

[0054] The holder can in particular have a holder socket and a holder section. The holder socket can be inserted into the holder section and in particular protrude beyond the holder section on the end face facing the vacuum cleaning attachment. The holder socket and the holder section can be connected to one another in a form-fitting and / or friction-fitting manner, in particular can be inserted into one another. The holder section can preferably be designed as a cylindrical hollow body, which is particularly preferably open at the end faces. The holder socket can in particular have the coding device and / or the mating contacts. The holder socket serves in particular for electrically contacting the lighting device. Because the holder socket and the holder section are optionally detachable from one another, the holder section can be equipped without electrical functionality, which can simplify the manufacture of the holder.

[0055] The mating contacts can be supplied with electrical power via cable guides. These cable guides can be routed through the interior of the quiver section if necessary, thus protecting them from external influences or damage.

[0056] The quiver section can be designed to accommodate at least part of the suction cleaning attachment.

[0057] In a further preferred embodiment, the holder can furthermore have a base section at its end opposite the open end designed to receive the vacuum cleaning attachment. The base section can particularly preferably be detachably connected to the holder section. Preferably, the holder section can be plugged onto the base section at least in part and thus connected to the base section in a form-fitting and / or friction-fitting manner. The base section can in particular form a closed end face of the holder. In particular, the base section projects above and / or away from the open end face of the holder section facing the base section or is arranged in alignment with the latter. Accordingly, the base section can in particular have a first tapered area for arranging and plugging on the holder section and a second area projecting away from the first area.

[0058] In the base section, in particular in the second region of the base section, charging electronics can be provided to supply power to the mating contacts. In particular, the cable guides connected to the mating contacts are also connected to the charging electronics. The charging electronics can in particular have a power connection located outside the holder for supplying the charging electronics. In particular, the charging electronics can be supplied with an electrical voltage of 230 V + / - 20% and / or 110 V + / - 20%. The voltage supply of the charging electronics can in particular depend on the respective power grid. The charging electronics can further be designed to supply the mating contacts and / or the accumulator of the lighting unit with the required electrical voltage.For this purpose, the charging electronics can, in particular, comprise a voltage converter, which converts the excessive voltage supplied to the charging electronics to lower voltage values for supplying the battery. This lower voltage can then be transmitted to the battery, in particular through the interaction between the contacts and the mating contacts.

[0059] In particular, the charging electronics are firmly connected, preferably by a material bond, to the base section. Accordingly, the charging electronics can be arranged in the base section in a captive manner.

[0060] Particularly preferably, the base section has a compensating means on its end face facing away from the quiver section for adaptation and / or arrangement on different surfaces. The end face facing away from the quiver section can be open or closed. The compensating means enables the quiver to be arranged on different surfaces, in particular, whereby unevenness on a flat surface can be compensated. The compensating means can be designed, in particular, to protect the charging electronics from external influences such as moisture, dirt, etc.

[0061] The compensating means preferably comprises a groove in the edge of the base section on the end face facing away from the quiver section and a seal that can be inserted or is inserted into the groove, in particular an annular seal, preferably made of silicone, natural rubber, and / or synthetic rubber. The seal can position the base section on a flat surface with uneven areas and, in particular, compensate for these uneven areas as needed.

[0062] Furthermore, the base section can have fastening receptacles, in particular screw receptacles, for fastening, in particular force-fitting, to a surface. The firm fastening of the base section to a surface can ensure the entire attachment of the holder to that surface. The holder section can be connected to the base section, and the holder support can be connected to the holder section. Accordingly, the base section can support the entire holder on a surface to which the base section is connected.

[0063] Particularly preferably, the holder, in particular the base section, has a display means, in particular a light source, preferably an LED. The display means can display the inserted state of the vacuum cleaning attachment in the holder and / or an ongoing charging of the battery of the lighting device and / or the power supply of the charging electronics. The aforementioned states can be displayed in particular via a color, for example green and red. Particularly preferably, the display means provides the user with information about whether the battery of the lighting device is currently being charged. When the charging process of the battery of the lighting device is complete, this can particularly preferably be displayed to a user, for example by a color change of a light source of the display means.The user therefore receives preferential information about the charge level of the battery and can therefore use the vacuum cleaning attachment optimally.

[0064] Furthermore, in a particularly preferred embodiment, it is provided that the quiver and / or the vacuum cleaning attachment, preferably the circuit board, has a circuit for deactivating the illuminant when the vacuum cleaning attachment is not in use.

[0065] Furthermore, a control device can preferably be provided that has charging electronics to ensure deep discharge and / or overcharge protection. Overcharging of the battery can also be prevented accordingly thanks to the charging electronics.

[0066] The stationary cleaning device has a central vacuum cleaner system or a central operating unit in which all technical components necessary for the operation of the cleaning device, for example the blower device or control and / or regulating devices or related electronic components, are housed.

[0067] To supply the vacuum cleaning attachment with suction air, a hose connected to the central vacuum cleaner system or the blower unit is provided, preferably with the vacuum cleaning attachment being connected to the hose at an end facing away from the suction opening or at the handle. A positive and / or non-positive connection is preferably provided.

[0068] The blower device is particularly designed such that a negative pressure of between 0.3 and 0.8 bar, preferably between 0.4 and 0.6 bar, prevails in the suction channel during suction operation. This negative pressure ensures effective suction of the dirt particles.

[0069] Furthermore, in a particularly preferred embodiment, it is provided that the central vacuum cleaner system has a control device which supplies the charging current to the quiver for charging the accumulator.

[0070] Alternatively or additionally, the control device is designed to deactivate the lamp when not in use or when charging and / or when inserted into the holder. The control device for deactivating the lamp when not in use or when charging can be part of the holder or the vacuum cleaning attachment, in particular the lighting device, particularly preferably the circuit board.

[0071] Preferably, a plurality of vacuum cleaning attachments, preferably at least two, can be connected to the central vacuum cleaner system or to the blower device. It is understood that the energy supplied to the blower device can ultimately also be reduced as soon as at least one vacuum cleaning attachment is arranged in a holder. According to the invention, continuous suction operation can be provided, so that a pressure-tight seal between an edge of the holder and a stop on the vacuum cleaning attachment, which is preferably arranged on the handle, is advantageous in terms of energy and / or operating costs.

[0072] According to a further preferred embodiment of the present invention, it is provided that the quiver and / or the quiver section is formed as a hollow cylinder and in particular is closed at the end, preferably wherein the coding device is arranged at the open end of the quiver.

[0073] In particular, the holder is provided with an edge for interacting with the stop of the suction cleaning attachment when not in use, particularly preferably so that a pressure-tight seal is created between the suction cleaning attachment and the holder. The edge and the interacting stop ensure secure axial fixation of the suction cleaning attachment relative to the holder when not in use or when charging. This ensures secure alignment between the contacts and the mating contacts and facilitates handling.

[0077] Fig. 1shows a suction cleaning attachment 1 of a cleaning device 2 for use in cleaning the interior of motor vehicles using a suction air flow. The suction cleaning attachment 1 is designed to be inserted and held in a holder 3 when not in use.

[0078] A holder for the suction cleaning attachment 1 in the quiver 3 is in Fig. 10 The non-use condition ultimately occurs before and after the interior cleaning of the motor vehicles or when the suction cleaning attachment 1 is not used for In In this state, the suction cleaning attachment 1 can be inserted into the quiver 3, as shown Fig. 10 visible, used and maintained.

[0079] The suction cleaning attachment 1 has an internal suction channel 4 - as also Fig.10visible - for guiding the suction air flow. The suction channel 4 is formed within a housing 5 of the vacuum cleaning attachment 1, wherein the housing 5 has a handle 6 with a gripping area 7 and a housing nozzle 8, preferably arranged detachably from and / or movable relative to the handle 6, with an end suction opening 9 of the suction channel 4.

[0080] Fig. 1 shows that the suction cleaning attachment 1 has a lighting device 10.

[0081] Advantageously, a taper of the suction channel 4 in the housing socket 8 in the direction of the end-side suction opening 9 is provided, wherein the suction channel 4 has a substantially hollow cylindrical shape along the handle 6 and at the transition from the handle 6 to the housing socket 8 changes into an at least substantially slit-like shape, preferably continuously tapering in the direction of the suction opening 9, as can also be seen from Fig. 6 is evident.

[0082] In the illustrated and preferred embodiment, the lighting device 10 has two illuminants 11. However, it is also possible for only a single illuminant 11, for example in the form of a light strip, to be provided. More than two illuminants 11 or any desired number of illuminants 11 can also be provided. The illuminant 11 is preferably designed as an LED.

[0083] The light source 11 is directed at least partially in the direction of the suction opening 9. This enables the area to be cleaned or the area surrounding the suction opening 9 to be illuminated by the light beam or light cone emerging through the light source 11.

[0084] To prevent contamination of the lamp 11 or the LED, to maintain the luminosity of the LED, and / or to minimize mechanical stress, a protective device (not shown in detail), in particular an at least partially transparent cover, can be connected to the lamp 11. The lamp cover and / or the protective device can be replaced periodically. The protective device can also be detachably connected to the housing 5, in particular latched.

[0085] Preferably, the illuminants 11 can illuminate the surfaces in the vehicle interior to be vacuumed and / or cleaned in a targeted and purposeful manner. Advantageously, the illuminants 11 radiate beyond the suction opening 9 and are attached to the housing connector 8. This allows comparatively poorly illuminated areas in the vehicle interior, for example, between the vehicle seats, to be illuminated or illuminated by the illuminants 11.

[0086] The lighting device 10 and the lamps 11 are arranged on the outside of the housing 5 and the housing nozzle 8, respectively. This provides circumferential illumination of the housing nozzle 8 and the peripheral area of the suction opening 9.

[0087] As shown by Fig. 1As can also be seen, the suction cleaning attachment 1 has a mouthpiece 40, with the suction opening 9 being formed on or in the mouthpiece 40. The mouthpiece 40 is detachably connected to the housing socket 8, in particular can be pushed on linearly. The mouthpiece 40 is designed as a wearing part and is subject to increased wear in the area of the suction opening 9 due to friction or direct contact with the surfaces to be vacuumed or cleaned.

[0088] The nozzle 40 may have a wear indicator or marking (not shown in detail) to indicate when, due to progressive abrasion, replacement of the worn nozzle 40 is indicated. Without the nozzle 40, wear on the suction cleaning attachment, in particular on the housing nozzle 8, would result in the entire disposal of the nozzle, which, depending on the intensity of use, would be the case after a relatively short period of several weeks, for example, six weeks. This would affect the replacement or reconnection of the lighting devices 10 connected to the housing nozzle 8, which would be correspondingly time-consuming and costly if the entire housing nozzle 8 were to be replaced.

[0089] Fig. 2 shows that the lighting device 10 has an accumulator 12 for the electrical supply of the lighting means 11.

[0090] The accumulator 12 is preferably a lithium-ion accumulator or a lithium accumulator and / or has a flat design. In the illustrated and preferred embodiment, the accumulator 12 is designed in the shape of a flattened cuboid or rectangular.

[0091] The lighting device 10 is arranged on the outside of the housing socket 8 and has at least one lighting unit 13 which can be at least partially detached from the housing 5 or from the housing socket 8.

[0092] In the illustrated and preferred embodiment, the lighting unit 13 comprises the accumulator 12, the illuminating means 11, and a circuit board 14 electrically connected to the accumulator 12 and the illuminating means 11. The circuit board 14 is designed as a printed circuit board or signaling carrier for the accumulator 12 and the illuminating means 11. In particular, the circuit board 14 serves to electrically control the illuminating means 11, with the corresponding electrical supply being ensured via the accumulator 12. At the same time, the circuit board 14 also serves, in particular detachably, for the mechanical fastening of the accumulator 12 and the illuminating means 11 to the housing support 8.

[0093] In the illustrated and preferred embodiment, the lighting means 11 are arranged adjacent to the accumulator 12 on the circuit board 14.

[0094] The circuit board 14 is detachably connected to the housing socket 8, for example by screwing.

[0095] The lighting device 10 or the lighting unit 13 has a cover 15 which can be detachably connected to the housing socket 8 for covering the accumulator 12, the lighting means 11 and the circuit board 14.

[0096] As in Fig. 3As can be seen, the cover 15 has, on its front side or its side facing the suction opening 9, illumination openings 16 in which the illuminants 11 are at least partially received and / or held. In the use state, the illuminants 11 shine through the illumination openings 16 in the direction of the suction opening 9. At the same time, the illuminants 11 are held within the illumination openings 16 on the cover 15. The cover 15 engages with its front side and, preferably, with its two opposite side wall sections, over the accumulator 12 and the circuit board 14 or covers the accumulator 12 and the circuit board 14 at the front and / or sides, preferably completely and / or up to the housing socket 8.

[0097] As in Fig. 2As shown, the lighting device 10 has two contacts 17 for electrical interaction with mating contacts 18 of the holder 3. The contacts 17 are supported on the circuit board 14, preferably spring-loaded and / or by means of contact springs 19. The contact springs 19 are electrically connected to the circuit board 14. As a result, the contacts 17 are electrically conductively connected to the circuit board 14 via the contact springs 19. However, it is understood that instead of the contact springs 19, other connecting means having spring-elastic properties and being electrically conductive can also be provided for connecting the contacts 17 to the circuit board 14.

[0098] In the preferred embodiment shown, the contacts 17 are designed as spring-loaded balls, which at least partially protrude beyond the lighting device 10 and / or the cover 15, as shown in Fig. 6 illustrated.

[0099] The contacts 17 are arranged on a side of the circuit board 14 facing away from the lighting means 11, preferably with the accumulator 12 being arranged between the lighting means 11 and the contacts 17 on the circuit board 14, cf. Fig. 2 .

[0100] As shown by Fig. 3As can be seen, two contact openings 20 are provided on the upper side of the cover 15 for receiving the contacts 17, such that the contacts 17, as pressure contacts or points, partially protrude through the contact openings 20 relative to the upper side of the cover 15 in the use state, in particular under the action of the spring force or the contact springs 19. Accordingly, the contacts 17 are exposed and / or accessible on the upper side of the cover 15 in the use state. At the same time, the contact openings 20 form an axial stop for the contacts 17 in the use state or in the non-charging state. Accordingly, the contact openings 20 have a reduced diameter compared to the spherical contacts 17, at least in the region of the upper side of the cover 15.

[0101] As also in Fig. 3As shown, recesses 21, in particular groove-shaped, are provided on the upper side of the cover 15, starting from the contacts 17 and extending in the direction of the suction opening 9, preferably wherein the recesses 21 extend in the direction of the suction opening 9 and / or up to the front side of the cover 15.

[0102] It should be noted, however, that the recesses 21 are only one possible variant and are not to be seen as mandatory for implementing a smooth or low-wear connection between the contacts 17 and the mating contacts 18.

[0103] When the vacuum cleaning attachment 1 is inserted into the holder 3, the mating contacts 18 enter the recesses 21, preferably without contact or friction, starting from the front of the cover 15. In the fully inserted state or in the non-use and / or charging state, contact is then made between the mating contacts 18 and the contacts 17, after the mating contacts 18 have completely passed through or traversed the recesses 21 in the direction of the contacts 17.

[0104] When the suction cleaning attachment 1 is pulled out of the holder 3, the mating contacts 18 can then, starting from the contacts 17 or after the electrical connection to the contacts 17 has been broken, move over the cover 15 along the recesses 21 without contact or friction. This effectively prevents wear of the mating contacts 18 or the cover 15 as a result of rubbing against each other when inserting or removing the suction cleaning attachment 1 into or from the holder 3.

[0105] As shown by Fig. 4As can be seen, the cover 15 also has, starting from the contact openings 20, preferably cylindrical bearing sections 22 on the underside and / or projecting towards the circuit board 14 or the housing socket 8, for receiving the contact springs 19 and / or the contacts 17. When covered by the cover 15, the contacts 17 and the contact springs 19 engage on the underside in the bearing sections 22. As a result, the contacts 17 and the contact springs 19 are securely mounted axially by means of the bearing sections 22.

[0106] For the detachable fastening of the cover 15 to the housing socket 8, a hook section 23 is provided on the underside of the front side of the cover 15, which hook section interacts with a complementary hook section provided on the housing socket 8 and not shown in detail.

[0107] Accordingly, the cover 15 is hooked onto the housing socket 8 at its front side. However, it is understood that corresponding connecting sections, for example hook sections, can also be provided on at least one long side and / or on the rear of the cover 15 to enable the cover 15 to be connected to the housing socket 8. Other snap and / or clamp connections, which are familiar to those skilled in the art, can also be implemented to connect the cover 15 to the housing socket 8. Ultimately, the cover 15 can be connected to the housing socket 8 in a wide variety of ways.

[0108] In the illustrated and preferred embodiment, a fastening opening 24 is provided on the side or rear side of the cover 15 opposite the front side, through which a fastening means 25, for example a screw, extends and is connected, in particular screwed, to the housing socket 8 in the fastened state.

[0109] At the Fig. 5 In the embodiment of the vacuum cleaning attachment 1 according to the invention shown, it is provided that the lighting device 10 is designed as a separate lighting unit 13 that can be separated from the housing socket 8. In other words, the lighting unit 13 is designed as a detachable or separately mountable and / or independently manageable interchangeable unit.

[0110] As an independent structural unit or lighting unit 13, the lighting unit 13 comprises according to Fig. 5thus all electrical or electrically operable components, in particular the lighting means 11, the accumulator 12 and the contacts 17 and / or circuit board 14. In the illustrated and preferred embodiment, the lighting unit 13 has a housing or a base body 26 which preferably encloses it on all sides and in which the lighting means 11, the accumulator 12, the circuit board 14 and the contacts 17 are accommodated.

[0111] The base body 26 of the lighting unit 13 can be detachably connected to the housing socket 8, in the illustrated example by a correspondingly indicated plug and / or snap connection 27, wherein the lighting unit 13 can be pushed linearly onto the housing socket 8 and then, for detachable fixing to the housing socket 8, can be correspondingly locked to the housing socket 8 by means of the plug and / or snap connection 7.

[0112] However, it is understood that the solution by means of the hook sections, as previously explained with regard to the first embodiment, can also be realized in the separately formed lighting unit 13.

[0113] As shown by the Fig. 6 As can be seen from the schematic side view shown, the lighting device 10 or the lighting unit 13 is arranged at the transition area of the housing socket 8 to the handle 6.

[0114] It is also evident that the distance of the illuminants 11 or the lighting device 10 and / or the lighting unit 13 from the suction opening 9 corresponds to at least 60%, preferably at least 70%, of the distance from the suction opening 9 to the handle 6 and / or the handle area 7. As a result, a large part of the housing socket 8, starting from the suction opening 9, is free of the lighting device 10 or the lighting unit 13 and is therefore not increased in its external dimensions. This does not impair the cleaning of hard-to-reach areas, preferably in the area of driver's seats, so that there is no need to worry about any loss of handling compared to conventional housing sockets 8 or vacuum cleaning attachments not equipped with a lighting device 10.

[0115] In the illustrated and preferred embodiment, it is also provided that the housing socket 8 has two opposite flat sides 28, 29 starting from the suction opening 9, preferably wherein the flat sides 28, 29 merge into a circular cross-section of the suction channel 4 at the transition area to the handle 6.

[0116] The flat sides 28, 29 are preferably designed to taper continuously towards the suction opening 9.

[0117] The lighting devices 10 are arranged on opposite flat sides 28, 29. This enables a robust connection and almost circumferential illumination of the suction opening 9.

[0118] Accordingly, in the illustrated and preferred embodiment, two preferably identically designed lighting devices 10 or lighting units 13 are provided, which are arranged opposite one another on the flat sides 28, 29 of the housing socket 8.

[0119] Fig. 7 shows a stationary cleaning device 2 for use in cleaning the interior of motor vehicles. The cleaning device 2 has a suction cleaning attachment 1 according to one of the previously described embodiments. A blower device 30 of the stationary cleaning device 2 is assigned to the suction channel 4 and serves to generate a negative pressure. The blower device 30 is connected to the suction channel 4 of the suction cleaning attachment 1 via a hose 31.

[0120] In particular, the hose 31 is connected to the connection end of the suction cleaning attachment 1 or the handle 6 facing away from the suction opening 9.

[0121] The blower device 30 is preferably stationary or, for most of its use, is fixedly or immovably connected to a surface. Accordingly, the stationary cleaning device 2 is to be understood as distinct from mobile cleaning or suction devices, such as those used in the household sector as portable or movable mobile cleaning devices.

[0122] Fig. 8 shows a quiver 3 of the cleaning device 2 for holding the suction cleaning attachment 1 when not in use.

[0123] The quiver 3 has mating contacts 18 for interacting with the contacts 17 of the lighting device 13. The mating contacts 18 are preferably designed as sliding contacts.

[0124] However, it is understood that, according to an embodiment not shown in detail, a reversed design of the contacts 17 and the mating contacts 18 can also be implemented, wherein the mating contacts 18 are designed as pressure points or pressure contacts and / or as spring-loaded contact balls and the contacts 17 are designed as sliding contacts.

[0125] When the vacuum cleaning attachment 1 is inserted into the holder 3, an electrical connection is established between the contacts 17 and the counter contacts 18, such that the accumulator 12 is charged when not in use or when the vacuum cleaning attachment 1 is charged. Accordingly, the holder 3 is connected to a power source (not shown in detail), which can preferably be part of the stationary control device 2 or the central vacuum cleaner system or operating unit.

[0126] The quiver 3 has a preferably cylindrical quiver housing 32, wherein the quiver housing 32 has an open end and a closed end, as in Fig. 9 The suction cleaning attachment 2 can be inserted or introduced into the quiver housing 32 via the open end.

[0127] Furthermore, the quiver 3 has, in particular at the open end of the quiver housing 32, a coding device 33 which is designed so that the suction cleaning attachment 1 can only be inserted into the quiver 3 in such a way that the contacts 17 electrically contact the counter contacts 18.

[0128] The coding device 33 has a coding opening 34 or coding geometry, which ensures that the housing socket 8, with the suction opening 9 first, can only be fully inserted into the quiver 3 in such a way that the contacts 17 are in the correct orientation or alignment with the mating contacts 18 in the inserted state.

[0129] The coding opening 34 is, as can be seen from Fig. 9 visible, at least partially delimited by two opposing, preferably flat, coding surfaces 35. The mating contacts 18 are arranged or held on the coding surfaces 35.

[0130] The mating contacts 18 are recessed into the coding surfaces 35 and exposed via corresponding openings on the coding surfaces 35, preferably by at least 2 mm. When the vacuum cleaning attachment 2 is inserted, the contacts 17 then snap into the associated coding surfaces 35 in the area of the mating contacts and thus contact the recessed mating contacts 18. The spherical contacts 17 are held in the openings on the coding surfaces 35 when snapped in.

[0131] When the suction cleaning attachment 2 is inserted into the quiver 3 or in the charging state, as shown in Fig. 10As can be seen, the covers 15 of the lighting devices 10 are opposite the coding surfaces 35. The distance between the opposite coding surfaces 35 is only slightly greater than the distance between the adjacent upper sides of the covers 15 of the lighting devices 10. This ensures that the lighting devices 10 and ultimately the housing socket 8 are held essentially free of play and / or rotationally fixed and / or transversely fixed to the opposite coding surfaces 35 and, preferably, is held movable in the axial direction. This in turn enables precise and reliable contact between the contacts 17 and mating contacts 18. In addition, the vacuum present in the holder 3 draws the suction cleaning attachment 1 into the inserted state or non-use state and / or positional state.

[0132] In the preferred embodiment shown, the vacuum cleaning attachment 1 has a stop 38 designed as a step, which preferably projects beyond the handle area 7 and / or the lighting device 10 and is provided or designed to interact with an edge 39 of the holder 3, preferably the coding device 33. The stop 38 is preferably provided at the transition area from the handle 6 to the housing socket 8 and / or adjacent to the lighting device 10.

[0133] Preferably, the coding device 33 can be inserted into the open end of the quiver housing 32. In addition to the coding surfaces 35, the coding opening 34 is delimited by circular sections that border the coding surfaces 35 and are preferably designed to complement the outer circumference of the housing socket 8 adjacent to the lighting devices 10. In this respect, the coding opening 34 is designed to be at least substantially complementary or precisely fitting to the circumferential shape of the housing socket 8 in the region of the lighting devices 10 connected thereto.

[0134] At the open end of the quiver housing 32, the coding device 33 can have an insertion section that is at least partially funnel-shaped.

[0135] The coding device 33 can have at least one funnel-shaped insertion section and / or guide section both at the open end of the quiver housing 32 and opposite thereto. This enables a defined insertion and withdrawal movement of the suction cleaning attachment 1 into or out of the quiver 3 and also prevents the nozzle 40 from being pulled off the housing connector 8.

[0136] In Fig. 9 It is also shown that at least one, in the illustrated example two, cable guides 36 are arranged in the quiver housing 32. The cable guides 36 serve to guide the power supply lines for the mating contacts 18 within the quiver 23 or quiver housing 32.

[0137] In the illustrated and preferred embodiment, the cable guides 36, starting from the coding device 33, are routed within the receptacle housing 32 and pass through the closed end of the receptacle housing 32 to a power source (not shown in detail). However, it is understood that other design solutions for routing cables inside the receptacle housing 32, for example, through ring channels or the like, can also be implemented. External cable routing outside the receptacle 3 or receptacle housing 32 for powering the mating contacts 18 is also possible.

[0138] At the Fig. 11The stationary cleaning device 2 shown illustrates that a plurality of suction cleaning attachments 1, preferably at least 5, particularly preferably at least 10, in particular at least 20, suction cleaning attachments 1 can be provided to correspondingly form a plurality of suction points or suction locations. In this case, the suction cleaning attachments 1 are connected to a central vacuum cleaner system 37 or a central operating unit of the cleaning device 2, wherein the vacuum cleaner system 37 preferably comprises at least the blower device 30. The power supply to the holders 3 is preferably via the vacuum cleaner system 37, wherein the vacuum cleaner system 37 has corresponding control and / or regulating devices for this purpose.

[0139] In Fig. 12 Another embodiment of a quiver 3 is shown in an exploded view. In the Fig. 12In the illustrated embodiment, the quiver 3 has a quiver socket 41, a quiver section 42 and a base section 43. The quiver socket 41 can be plugged onto the open end face of the quiver section 42 facing the suction cleaning attachment 1. Fig. 13 shows that in the assembled state, the quiver socket 41 can at least partially protrude beyond and / or protrude beyond the quiver section 42 or be aligned with it.

[0140] The quiver socket 41 can have the coding device 33 and the mating contacts 18. The mating contacts 18 can be supplied with electrical power via cable guides 36. The quiver socket 41 can have openings for the passage of the cable guides 36, such as the Fig. 12 schematically shows. In Fig. 14The cable guides 36 are not shown in detail, so that the openings or recesses of the quiver socket 41 for these cable guides 36 are clearly visible. The cable guides 36 can be designed in particular to be electrically conductive and particularly preferably as power lines.

[0141] The quiver section 42 can in particular be placed on the base section 43 and / or connected to the base section 43 in a form-fitting and / or friction-fitting manner. Fig. 13 shows that in the assembled state the base section 43 projects beyond the quiver section 42 or protrudes relative to it.

[0142] Fig. 12further shows that the quiver section 42 is also open on the end face facing the base section 43. The quiver section 42 can, in particular, be designed as a hollow cylinder and preferably serves to at least partially accommodate the vacuum cleaning attachment 1 in the loaded state. The quiver section 42 can, in particular, be functionally compared to the quiver housing 32, which was previously described in connection with another embodiment of the quiver 3.

[0143] The cable guides 36 can extend through the quiver section 42 and be connected to the base section 43.

[0144] Furthermore, the Fig. 12that the base section 43 has charging electronics 46. The charging electronics 46 can be supplied with electrical energy externally. The cable guides 36 are connected, in particular, to the charging electronics 46. The charging electronics 46 can have a voltage converter for providing the electrical voltage required to charge the battery pack 12.

[0145] Furthermore, the bottom section 43 can have a first, tapered region 44 and a second region 45 projecting from the first region 44, as shown in FIG. Fig. 12 schematically shows. The second region 45 serves in particular to accommodate the charging electronics 46. The first region 44 can be arranged in the quiver section 42 when the quiver 33 is in the assembled state. The second region 45 is preferably used for attachment to a surface, for example, a pipe or the like. Electrical contact is made, in particular, with the charging electronics 46 via this surface.

[0146] For fastening to a surface, fastening receptacles 48, in particular screw receptacles, can be arranged in the second area 45, as the Fig. 12 The fastening receptacles 48 can be designed to accommodate connecting means for a force-locking connection to the surface.

[0147] The Fig. 12 shows that the bottom section 43 is open at its end facing away from the quiver section 42. This end can be arranged on a surface, which is described in more detail in Fig. 13 is shown. For arrangement on this surface, the base portion 43 can have a compensating means 47. The compensating means 47 can, in particular, compensate for unevenness of an at least substantially straight surface and thus, in the assembled state of the quiver 3, protect in particular the charging electronics 46 from external influences.

[0148] It is not shown in more detail that the compensating means 47 can be formed by a groove provided in the base section 43, in particular in the circumferential edge of the end face facing away from the quiver section 42, and by a seal inserted into the groove. List of reference symbols:
