Abstract

Claims (37)

1 . An assembly ( 1 ) comprising:

a component body ( 2 ); and

a fastening body ( 3 ) for fastening the component body ( 2 );

wherein the component body ( 2 ) is connectable to the fastening body ( 3 ) via a bayonet closure ( 4 ) of the assembly ( 1 );

wherein the bayonet closure ( 4 ) comprises:

a bayonet projection ( 5 ); and

a bayonet groove ( 6 ), the bayonet projection ( 5 ) being guided in and along the bayonet groove ( 6 );

wherein the bayonet groove ( 6 ) comprises:

an introduction portion ( 60 ), the bayonet projection ( 5 ) being introducible into the bayonet groove ( 6 ) in an introduction direction (E) via the introduction portion ( 60 );

a function portion ( 61 ) extending laterally with respect to the introduction direction (E) away from the introduction portion ( 60 ) and opening at a distal end thereof in a locking portion ( 62 ) for securing the bayonet projection ( 5 ) in a locking position;

a blocking portion ( 63 ) connecting the function portion ( 61 ) to the introduction portion ( 60 ); and

a pocket portion ( 64 ) extending between the blocking portion ( 63 ) and the locking portion ( 62 ) away from the function portion ( 61 ) counter to the introduction direction (E), the bayonet projection ( 5 ) being at least partially receivable in the pocket portion ( 64 ) in a holding position;

wherein the assembly ( 1 ) further comprises a blocking element ( 7 ) selectively positionable in a blocking position in the blocking portion ( 63 ) in order to block a passage for the bayonet projection ( 5 ) in the bayonet groove ( 6 ) between the insertion portion ( 60 ) and the functional portion ( 61 ); and

wherein the assembly ( 1 ) is configured such that the blocking portion ( 63 ) is at least partially exposed in the holding position so as to position the blocking element ( 7 ) in the blocking portion ( 63 );

wherein the assembly ( 1 ) is a luminaire, and the component body ( 2 ) comprises or is a luminaire housing;

wherein the luminaire housing comprises a light source.

2 . The assembly ( 1 ) according to claim 1 , wherein the component body ( 2 ) comprises the bayonet projection ( 5 ) and wherein the fastening body ( 3 ) comprises the bayonet groove ( 6 ).

3 . The assembly ( 1 ) according to claim 1 , wherein in the holding position, the blocking element ( 7 ) is movable selectively between the blocking position and a release position, wherein the blocking element ( 7 ) in the release position releases the passage for the bayonet projection ( 5 ) in the bayonet groove ( 6 ) between the insertion portion ( 60 ) and the functional portion ( 61 ).

4 . The assembly ( 1 ) according to claim 3 , wherein the blocking element ( 7 ) comprises or is a screw ( 70 ).

5 . The assembly ( 1 ) according to claim 4 , wherein the screw is movable between the blocking position and the release position by a screwing movement of the screw.

6 . The assembly ( 1 ) according to claim 3 , wherein the blocking element ( 7 ) has a pressure piece ( 71 ) with a movable pressure part ( 72 ), wherein the pressure part ( 72 ) is preloaded into the blocking position by a compression spring in order to block the passage for the bayonet projection ( 5 ) in the bayonet groove ( 6 ) between the introduction portion ( 60 ) and the function portion ( 61 ).

7 . The assembly ( 1 ) according to claim 6 , wherein the pressure piece ( 71 ) is configured such that the pressure part ( 72 ) is selectively transferrable from the blocking position into the release position counter to the preload of the compression spring.

8 . The assembly ( 1 ) according to claim 1 , wherein the component body ( 2 ) at least partially or completely receives the fastening body ( 3 ) in the locking position.

9 . The assembly ( 1 ) according to claim 1 , wherein the bayonet groove ( 6 ) is completely covered in the locking position.

10 . The assembly ( 1 ) according to claim 1 , wherein the blocking portion ( 63 ) is configured according to a first option or a second option, or both, wherein:

in the first option, the blocking portion ( 63 ) branches off from an end of the insertion portion ( 60 ) that is opposite an insertion opening ( 66 ) for the bayonet projection ( 5 ) into the bayonet groove ( 6 ); and

in the second option, the blocking portion ( 63 ) branches off from an end of the introduction portion ( 60 ) that is distal with respect to the introduction direction (E).

11 . The assembly ( 1 ) according to claim 1 , wherein the function portion ( 61 ) tapers toward the locking portion ( 62 ).

12 . The assembly ( 1 ) according to claim 1 , wherein the function portion ( 61 ) comprises a run-on slope ( 65 ) pointing in the introduction direction (E) and inclined toward the locking portion ( 62 ) in the introduction direction (E).

13 . The assembly ( 1 ) according to claim 1 , wherein the component body ( 2 ) and the fastening body ( 3 ) each have contact faces ( 21 , 31 ) directed toward one another with respect to the introduction direction (E), wherein the bayonet closure ( 4 ) is configured such that the contact faces ( 21 , 31 ) are pressed against one another in the locking position.

14 . The assembly ( 1 ) according to claim 1 , wherein the bayonet projection ( 5 ) has a round or angular cross-section, when viewed in its projection direction.

15 . The assembly ( 1 ) according to claim 1 , further comprising a plurality of respective bayonet closures, wherein the plurality of respective bayonet closures includes the bayonet closure ( 4 ).

16 . The assembly ( 1 ) according to claim 1 , wherein a basic shape or contour of the assembly ( 1 ) is angular or round when viewed in the insertion direction (E).

17 . The assembly ( 1 ) according to claim 15 , wherein the assembly ( 1 ) is further configured according to a first option or a second option, or both, wherein:

in the first option, at least one bayonet closure in the plurality of respective bayonet closures is positioned on each of two opposite sides of the assembly ( 1 ); and

in the second option, the plurality of respective bayonet closures is distributed along a circle.

18 . The assembly ( 1 ) according to claim 1 , wherein the fastening body ( 3 ) comprises mounting structures ( 30 ) for fastening the component body ( 2 ) connected thereto via the bayonet closure ( 4 ) to a mounting surface (M).
