Abstract

A spraying device includes a tool body, a handle, and an energy store. The tool body is carried by way of the handle and one end of the handle, on the opposite side to the tool body, includes a coupling for mechanically and electrically coupling an energy store. A cage is connected to the coupling incorporated in a top of the cage. The cage includes two webs curved in a U shape arranged opposite one another and are each connected to the top of the cage. In a coupled state, the energy store is received in an interior space of the cage in such a way that the two webs each protrude downward beyond a housing of the coupled energy store and into the space. The energy store is assigned a lower opening, a left-hand opening, a right-hand opening, a front opening and a rear opening of the cage.

First claim

The invention claimed is:

1 . A spraying device comprising
a tool body, a handle, and an energy store, wherein the tool body is carried by way of the handle and wherein one end of the handle, on an opposite side to the tool body, comprises a coupling for mechanically and electrically coupling the energy store, wherein the spraying device comprises a cage, wherein the cage is connected to the coupling in such a way that the coupling is incorporated in a top of the cage, wherein the cage comprises two webs curved in a U shape, wherein the two webs curved in the U shape are arranged opposite one another and are each connected to the top of the cage, wherein, in a coupled state, the energy store is received in an interior space of the cage in such a way that the two webs each protrude downward beyond a housing of the coupled energy store and into the space, and a lower opening, a left-hand opening, a right-hand opening, a front opening and a rear opening of the cage is allocated to the energy store.

2 . The spraying device as claimed in claim 1 , wherein each web, of the two webs curved in the U shape, forms, together with a lateral piece of the top of the cage, a frame which is closed around an entire periphery and which forms the left-hand opening and the right-hand opening, respectively.

3 . The spraying device as claimed in claim 1 , wherein a back piece of the top of the cage and a rear leg of at least one web of the two webs and a rear leg of at least one web of the two webs delimit a rear arch, which forms the rear opening of the cage.

4 . The spraying device as claimed in claim 3 , wherein an end piece of the top of the cage and a front leg of at least one web of the two webs and a front leg of at least one web of the two webs delimit a front arch, which forms the front opening of the cage.

5 . The spraying device as claimed in claim 4 , wherein the top of the cage, between the handle and a left-hand lateral piece and a right-hand lateral piece and the end piece and the back piece, comprises at least one through-opening leading into the interior space of the cage.

6 . The spraying device as claimed in claim 1 , wherein the spraying device is in the form of a HVLP paint spraying device or an airless paint spraying device.

7 . The spraying device as claimed in claim 1 , wherein the spraying device comprises a container for a fluid medium, a nozzle and a trigger.

8 . The spraying device as claimed in claim 7 , wherein a height of the cage is dimensioned such that, when a container is mounted, a standing surface of the cage lies in a common plane with a bottom of the container.

9 . The spraying device as claimed in claim 1 , wherein the two webs curved in the U shape are each in the form of a 2-component plastics element which comprises a tough and impact-resistant plastics part and plastics part, wherein a connection to the top of the cage is produced by the tough and impact-resistant plastics part and wherein a base region is formed by the plastics part.

10 . The spraying device as claimed in claim 1 , wherein the energy store is in the form of an electrical energy store.

11 . The spraying device as claimed in claim 1 , wherein, in a coupled state, the energy store or one of the energy stores is received in the interior space of the cage in such a way that each web of the two webs each protrude forward and rearward, respectively, beyond the housing of the coupled energy store and into the space.

12 . A handheld power tool system comprising a spraying device, a first energy store and a second energy store, wherein the first energy store is larger than the second energy store,
wherein the spraying device comprises a tool body and a handle, wherein the tool body is carried by way of the handle, wherein one end of the handle, on an opposite side to the tool body, comprises a coupling for mechanically and electrically coupling one of the energy stores, wherein the first energy store has a first cuboidal housing with a first width, a first height and a first depth and wherein the second energy store has a second cuboidal housing with a second width, a second height and a second depth, wherein the spraying device comprises a cage, wherein the cage is connected to the coupling in such a way that the coupling is incorporated in a top of the cage, wherein the cage comprises two webs curved in a U shape, wherein the two webs curved in the U shape are arranged opposite one another and are each connected to the top of the cage, wherein, in a coupled state, a respective energy store, of the first energy store or the second energy store, is received in the cage in such a way that the two webs curved in the U shape each protrude downward beyond the respective cuboidal housing of the respective energy store and into a space, and a lower opening, a left-hand opening, a right-hand opening, a front opening and a rear opening of the cage is allocated to the respective energy store, wherein an interior space of the cage is dimensioned such that the interior space can receive each of the first energy store or the second energy store alternatively.

13 . The handheld power tool system of claim 12 , wherein each web, of the two webs curved in the U shape, forms, together with a lateral piece of the top of the cage, a frame which is closed around an entire periphery and which forms the left-hand opening and the right-hand opening, respectively.

14 . The handheld power tool system of claim 12 , wherein a back piece of the top of the cage and a rear leg of at least one web of the two webs and a rear leg of at least one web of the two webs delimit a rear arch, which forms the rear opening of the cage.

15 . The handheld power tool system of claim 14 , wherein an end piece of the top of the cage and a front leg of at least one web of the two webs and a front leg of at least one web of the two webs delimit a front arch, which forms the front opening of the cage.

16 . The handheld power tool system of claim 15 , wherein the top of the cage, between the handle and a left-hand lateral piece and a right-hand lateral piece and the end piece and the back piece, comprises at least one through-opening leading into the interior space of the cage.

17 . The handheld power tool system of claim 12 , wherein the two webs curved in the U shape are each in the form of a 2-component plastics element which comprises a tough and impact-resistant plastics part and a-rubber like plastics part, wherein a connection to the top of the cage is produced by the tough and impact-resistant plastics part and wherein a base region is formed by the plastics part.

18 . The handheld power tool system of claim 12 , wherein the energy store is in the form of an electrical energy store.
