[0008] Finally, WO 2014 / 119130 A1 discloses a sprayer with a 36-volt specification, which is operated by connecting two rechargeable batteries with an 18-volt specification in series.

[0009] The invention is based on the object of proposing a spray device in which stability is ensured regardless of whether the container is filled and regardless of whether an energy storage device is coupled, or of proposing a hand-held power tool system in which stability is ensured regardless of whether the container is filled and regardless of which energy storage device is coupled.

[0010] This object is achieved on the basis of the features of the preamble of claim 1 and 2 by the characterizing features of claim 1 and 2, respectively. Advantageous and expedient developments are specified in the subclaims.

[0011] The spray device according to the invention comprises a machine body, a handle and an energy storage device, wherein the machine body is carried by the handle, wherein the handle comprises a coupling at the end opposite the machine body for mechanically and electrically coupling the energy storage device, wherein the spray device comprises a cage, wherein the cage is connected to the coupling in such a way that the coupling is integrated into a roof of the cage, wherein the cage comprises two U-shaped webs, wherein the U-shaped webs are arranged opposite one another and are each connected to the roof of the cage, wherein the energy storage device, in a coupled state, is accommodated in an interior of the cage in such a way that the U-shaped webs each protrude downwards over a housing of the coupled energy storage device into the space and provide the energy storage device with a lower opening, a left opening, a right opening,a front opening and a rear opening of the cage. By means of these openings, heat generated in the energy storage device during operation of the sprayer can be dissipated directly into the ambient air on five sides. This ensures reliable heat dissipation and prevents unwanted overheating. The sprayer according to the invention also provides for the sprayer to comprise a container for a liquid medium, a nozzle and an extractor, and in particular a fan. Such sprayers place great demands on the energy storage device and require good cooling of the energy storage device. The sprayer according to the invention also provides for the cage to be dimensioned in such a way thatthat the cage's base is level with the bottom of the container when the container is mounted. This significantly increases the sprayer's stability and ensures stability both when the container is full and when it is empty.

[0012] The handheld power tool system according to the invention comprises a spray device as well as a first energy storage device and at least one second energy storage device, wherein the spray device comprises a machine body and a handle, wherein the machine body is carried by the handle, wherein the handle comprises a coupling at the end opposite the machine body for the mechanical and electrical coupling of one of the energy storage devices, wherein the first energy storage device is designed as a large energy storage device and has a first cuboid-like housing with a maximum first width, a maximum first height and a maximum first depth, wherein the second energy storage device is designed as a small energy storage device and has a second cuboid-like housing with a maximum second width, a maximum second height and a maximum second depth, wherein the spray device comprises a cage, wherein the cage is connected to the coupling in such a way thatthat the coupling is integrated into a roof of the cage, wherein the cage comprises two U-shaped webs, wherein the U-shaped webs are arranged opposite one another and are each connected to the roof of the cage, wherein one of the energy storage devices is accommodated in the cage in a coupled state in such a way that the U-shaped webs each protrude downwards beyond the housing of the respectively coupled energy storage device into the space and the energy storage device is assigned a lower opening, a left opening, a right opening, a front opening and a rear opening of the cage, and wherein an interior of the cuboid-like cage is dimensioned in such a way,that it can alternatively accommodate each of the energy storage devices. By means of these openings, heat generated in the respective energy storage device during operation of the handheld power tool system can be dissipated directly into the ambient air on five sides, regardless of the size of the energy storage device. This ensures reliable heat dissipation and prevents unwanted overheating. In the handheld power tool system according to the invention, it is also provided that the spray device comprises a container for a liquid medium, a nozzle and an extractor, and in particular a fan. Such spray devices place great demands on the energy storage device and require good cooling of the energy storage device. In the handheld power tool system according to the invention, it is also provided that the cage is dimensioned in such a way thatthat the cage's base is level with the bottom of the container when the container is mounted. This significantly increases the sprayer's stability and ensures stability both when the container is full and when it is empty.

[0013] Furthermore, in the spray device or the handheld power tool system, each of the U-shaped webs, together with a side wall of the cage roof, forms a circumferentially closed frame through which the left opening and the right opening are formed, respectively. The U-shaped web and the side wall of the roof are formed in particular as a single piece. Such a construction offers multi-sided protection with minimal material expenditure and is easily implemented using injection molding technology.

[0014] The sprayer or handheld power tool system is also provided with a rear cheek of the cage roof and a rear leg of the left U-shaped curved web and a rear leg of the right U-shaped curved web defining a rear archway through which the rear opening of the cage is formed. This archway provides an ergonomically advantageous way of inserting and removing the energy storage unit from the interior of the cage. The insertion movement creates mechanical and electrical contact between the energy storage unit and the sprayer coupling. The mechanical contact also includes a mechanical locking of the energy storage unit to the coupling, ensuring that it is held securely.

[0015] Furthermore, the spray device or the handheld power tool system is provided with a front cheek of the cage roof and a front leg of the left U-shaped curved web and a front leg of the right U-shaped curved web defining a front archway through which the front opening of the cage is formed. Such a design avoids the formation of a transverse web, so that the energy storage device is directly accessible to the ambient air even in a transition area where a front end face of the energy storage device merges into a base surface of the energy storage device.

[0016] It is also provided in the sprayer or the hand tool system that the coupling is designed in a plate-like manner. This allows the coupling to be easily integrated into the roof of the cage, so that weight can be saved by forming part of the roof.

[0017] Furthermore, it is intended that the sprayer be designed as a paint sprayer, preferably as an HVLP paint sprayer or an airless paint sprayer. Due to the high continuous power requirements, the energy storage devices provided for such sprayers generate a large amount of heat that must be dissipated.

[0018] Furthermore, it is provided in the spray device or the handheld power tool system that the U-shaped bent webs are each designed as a 2-component plastic component, which comprise a tough and impact-resistant plastic part and a rubber-like plastic part, wherein the tough and impact-resistant plastic part creates the connection to the roof of the cage and wherein a foot area is formed by the rubber-like plastic part. This ensures, on the one hand, optimal protection of the energy storage device, for example if the spray device falls down, and on the other hand, stability is increased when the spray device is put down.

[0019] The sprayer or handheld power tool system is provided with at least one through-hole in the cage roof between the handle and the left and right side panels, the front and rear panels, and the rear panel, leading into the interior of the cage. This additionally enables cooling of a ceiling surface of the energy storage unit installed in the sprayer using ambient air, while simultaneously reducing the weight of the sprayer.

[0020] Furthermore, the sprayer or handheld power tool system is designed with the energy storage device as an electrical energy storage device, particularly as an accumulator. This design allows for a wide range of standardized accumulators to be available.

[0021] Finally, it is provided in the spray device or the hand-held power tool system that the or one of the energy storage devices is accommodated in the interior of the cage in a coupled state in such a way that the U-shaped webs protrude forwards and backwards over the housing of the coupled energy storage device into the space.

[0022] This cage provides even more comprehensive protection for the energy storage unit. Furthermore, it improves the sprayer's stability.

[0023] Further details of the invention are described in the drawing using schematically illustrated embodiments.

[0024] This shows: Figure 1: a side view of a hand-held power tool system according to the invention, which comprises a spray device; Figure 2: a perspective detailed view of the Figure 1known spray device in the area of ​​the cage; Figure 3: a view rotated approximately 180° around a vertical axis of the representation of the Figure 2 and Figure 4: a side view from the right of the Figure 1 shown sprayer in the cage area.

[0025] In the Figure 1A side view of a handheld power tool system 1 according to the invention is shown. The handheld power tool system 1 comprises a spray device 2, which is partially shown only with dashed lines, as well as a first energy storage device 101 and a second energy storage device 201. The spray device 2 comprises a machine body 3 and a handle 4. The machine body 3 is carried by the handle 4, and the handle 4 comprises a coupling 5 for the mechanical and electrical coupling of one of the two energy storage devices 101, 201, wherein the coupling 5 is located opposite the end of the machine body 3. The first energy storage device 101 is designed as a large energy storage device and has a first cuboid-like housing 102 with a maximum first width B102 (see Figure 4), a maximum first height H102 and a maximum first depth T102. The second energy storage device 201 is designed as a small energy storage device and has a second cuboid-like housing 202 with a maximum second width B202, a maximum second height H202 and a maximum second depth T202. Furthermore, the spray device 2 comprises a cage 51. The cage 51 is connected to the coupling 5 in such a way that the coupling 5 is integrated into a roof 52 of the cage 51. The cage 51 comprises two U-shaped webs 53, 54, wherein the U-shaped webs 53, 54 are arranged opposite one another and are each connected to the roof 52 of the cage 51. In the illustration of the Figure 1The first energy storage device 101 is shown in a state coupled to the coupling 5 and is accommodated in the cage 51 in such a way that the U-shaped webs 52, 53 protrude forwards - in the direction of arrow x' -, backwards - in the direction of arrow x - and downwards - in the direction of arrow y' - beyond the housing 102 of the first energy storage device 101 into the space R surrounding the spray device 2 and the first energy storage device 101. Thus, in the coupled state, the first energy storage device 101 is assigned a lower opening 55, a left opening 56, a right opening 57, a front opening 58 and a rear opening 59 of the cage 51. An interior space 60 of the cuboid cage 51 is dimensioned such that it can alternatively accommodate either of the two energy storage devices 101, 201.

[0026] In the perspective views of the Figures 2 and 3 are perspective detailed views of the Figure 1shown spray device 2 in the area of ​​the cage 51, wherein in the interior 60 of the cage 51 none of the energy storage devices is shown or in the Figure 2 only one edge of the energy storage device 101 is indicated by a dash-dotted line.

[0027] In the Figure 4 is a side view of the Figure 1 shown spray device 2, which is only shown in the area of ​​the cage 51. In this view, both energy storage devices 101, 201 are indicated by dash-dotted lines.

[0028] In the Figure 1The first energy storage device 101, which is designed as an accumulator 103, is shown schematically twice. The first energy storage device 101 is shown schematically by a thick contour line KL101 in a position inserted into the interior 60 of the cage 51. This thick contour line KL101 is to be understood only as a schematic representation of the position of the first energy storage device 101. The first energy storage device 101 is arranged in this position between the left U-shaped web 53 and the right U-shaped web 54 under the roof 52 (see in particular also Figures 2 and 3 ). The first energy storage device 101 is also schematically illustrated by a dashed line SL101 in a second position outside the cage 51. This indicates its retrievability from the interior 60 of the cage 51.

[0029] Furthermore, for alternative use, the second energy storage 201 is in the Figure 1shown schematically. This is also designed as an accumulator 203 and can be inserted into the interior 60 of the cage 51 instead of the first energy storage device 101 shown with the thick contour line KL101.

[0030] From the overview of the Figures 1 to 3 It can be seen that each of the U-shaped webs 53, 54, together with a side cheek 52a or 52b of the roof 52 of the cage 51, forms a circumferentially closed left frame 61 or right frame 62. Here, the left opening 56 is formed by the left frame 61, and the right opening 57 is formed by the right frame 62. Here, the U-shaped web 53 or 54 is formed in one piece with the side cheek 52a or 52b of the roof 52.

[0031] A rear cheek 52c of the roof 52 of the cage 51 and a rear leg 53b of the left U-shaped curved web 53 and a rear leg 54b of the right U-shaped curved web 54 form a rear archway 63 through which the rear opening 59 of the cage 51 is formed (see in particular Figure 4 ). Through this archway 63 it is ergonomically advantageous to, for example, insert the first energy storage device 101, which is located in the Figure 1represented by the contour line KL101, from the interior 60 of the cage 51 in the direction of arrow x. During withdrawal, a mechanical and electrical contact existing between the first energy storage device 101 and the coupling 5 is removed, wherein beforehand a locking device (not shown) via which the first energy storage device 101 is connected to the coupling 5 and / or the roof 52 is released. The release of this locking device preferably takes place in a conventional manner by means of a release button (not shown) arranged on a rear end face 105 of the first energy storage device 101, which is preferably actuated with the thumb. When withdrawing the first energy storage device 101, the remaining fingers rest in the region of the front opening 58 on a front end face 104 of the first energy storage device 101, wherein the palm of the hand lies opposite a bottom surface 107 of the first energy storage device 101 (see in particular Figure 1 ). Inserting one of the energy storage devices 101, 201 takes place in the reverse order, whereby the energy storage devices 101, 201 always have a cover surface 106 or 206 on a bottom side 52f (see Figure 4 ) of the roof 52 to ensure mechanical and electrical contact with the coupling 5.

[0032] By means of a front cheek 52d (see Figure 3) of the roof 52 of the cage 51 and a front leg 53a of the left U-shaped curved web 53 and a front leg 54a of the right U-shaped curved web 54, a front archway 64 is formed, which forms the front opening 58 of the cage 51. Accordingly, the front opening 58 and the lower opening 55 merge into one another without forming a transverse web. Thus, the first energy storage device 101 can be cooled unhindered by the ambient air in the space R, even in a transition region in which its front end surface 104 merges into its bottom surface 107. For explanation, Figure 2 a dash-dotted line indicates a lower front edge UVK101 of the first energy storage device 101, at which its front end face 104 merges into its bottom face 107 (compare Figures 1 and 2 ).

[0033] The coupling 5 of the spray device 2 is plate-like in the form of a coupling plate 6, which is centrally integrated into the roof 52 of the cage 51 in such a way that the roof 52 surrounds the coupling plate 6 (see in particular Figures 2 to 4 ).

[0034] As can be seen from the Figures 1 to 3 As can be seen, the spray device 2 is designed as a spray device 7. Specifically, the spray device 2 is designed as a paint spray device 8 in the manner of an HVLP paint spray device 9, which comprises a container 10 for a liquid medium (not shown), a nozzle 11 and an extractor 12, and in particular a fan 13 integrated into the machine body 3. The fan 13 comprises an electric motor which, by means of its fan wheel or other technology, generates an air stream which is used to spray paint from the container 10.

[0035] According to a statement included in the presentation of the Figure 3In the exemplary embodiment, it is also provided that the roof 52 of the cage 51 comprises two through openings 67, 68 leading into the interior 60 of the cage 51 for additional cooling of the energy storage device between the handle 4 and the rear cheek 52c.

[0036] The cage 51 is dimensioned in its height H51 such that a base 69 of the cage 51 with the container 10 mounted lies on a common plane E with a bottom 10a of the container 10 (see Figures 1 and 4 ).

[0037] Furthermore, a clear height of HL60 (see Figure 4 in conjunction with Figure 1) of the interior 60 of the cage 51 is dimensioned such that the interior 60 can accommodate both a small energy storage device 201, the housing 202 of which has a maximum height H202, and a large energy storage device 101, the housing 102 of which has a maximum height H102, such that between a standing plane SE defined by the standing surface 69 and a floor surface 107 or 207 of the housing 102, 202 of the energy storage device 101 or 201 there is a ventilation duct 70 sufficient for heat dissipation through the ambient air of the room R. As a result, the energy storage device 101 or 201 can also be cooled on its floor surface 107 or 207 by the ambient air of the room R when the spray device 2 is placed on a table or the like at the end of operation.

[0038] For all variants of the sprayer or handheld power tool system, the cage is structurally designed as a carriage, with the left connecting leg forming a left skid and the right connecting leg forming a right skid. The roof of the cage forms a transport surface for the carriage, to which the handle is mounted or with which the handle is integrally formed. The energy storage unit used to supply energy is housed between the skids and the transport surface. Energy storage units of various sizes can be used.

[0039] For all design variants, the U-shaped bent webs can also include additional struts, e.g. for further stiffening, so that the left opening and / or the right opening are divided.

[0040] A further embodiment provides that the left U-shaped bent web and the right U-shaped bent web are each connected to the roof of the cage only with the front leg or only with the rear leg, wherein it is particularly provided that only the front leg is connected to the roof of the cage and the rear leg ends freely in the space.
