Abstract
Abstract The invention relates to a device for connecting the plug-in base ( 5 ) of a side-mounting luminaire to a carrier tube ( 3 ), in particular to the tube ( 3 ) of a luminaire mast, it being possible for the plug-in base ( 5 ) of the side-mounting luminaire to be connected to the carrier tube ( 3 ) and to be fixed to the carrier tube ( 3 ) by means of a securing element ( 15 ) which can be inserted into the side-mounting luminaire from the outside inward, and it being possible for the securing element ( 15 ) to be pressed against an abutment which effects clamping. The securing element ( 15 ) cooperates with a clamping device ( 10 ) which, when the securing element ( 15 ) is inserted into the tube interior ( 12 ), converts the clamping force directed away from said element into the tube interior ( 12 ) into a clamping force directed outward from the tube interior ( 12 ), the clamping device ( 10 ) pressing a clamping member ( 11 b ) against the inner wall ( 17 ) of the carrier tube ( 3 ), which wall acts as the abutment ( 16 ).

A device for connecting the plug-in base ( 5 ) of a side-mounting luminaire to a carrier tube ( 3 ), in particular to the tube ( 3 ) of a luminaire mast, it being possible for the plug-in base ( 5 ) of the side-mounting luminaire to be connected to the carrier tube ( 3 ) and to be fixed to the carrier tube ( 3 ) by means of a securing element ( 15 ) that can be inserted into the side-mounting luminaire from the outside inward, and it being possible for the securing element ( 15 ) to be pressed against an abutment which effects clamping, characterized in that the securing element ( 15 ) cooperates with a clamping device ( 10 ) which, when the securing element ( 15 ) is inserted into the tube interior ( 12 ), converts the clamping force directed away from said element into the tube interior ( 12 ) into a clamping force directed outward from the tube interior ( 12 ), the clamping device ( 10 ) pressing a clamping member ( 11 b ) against the inner wall ( 17 ) of the carrier tube ( 3 ), which wall ( 17 ) serves as the abutment ( 15 ).
Claim 3
Dependent Claim
100 words
A device as claimed in claim 1 , characterized in that the clamping device ( 10 ) comprises a rocker arm ( 11 ) which is pivotably mounted in the plug-in base ( 5 ) such that the securing element ( 15 ) pressing from the outside inward against a first rocker arm end ( 11 a ) swivels the rocker arm ( 11 ) and presses the other rocker arm end ( 11 b ) from the inside outward against the inner wall ( 17 ) forming the abutment ( 16 ) of the carrier tube ( 3 ).
Claim 4
Dependent Claim
40 words
A device as claimed in claim 1 , characterized in that the securing element ( 15 ) to be actuated from the outside inward is a setscrew which is known per se and which is provided on the side-mounting luminaire.
Claim 5
Dependent Claim
39 words
A device as claimed in claim 1 , characterized in that the plug-in base ( 5 ) of the side-mounting luminaire can be plugged directly into an open end ( 4 ) of the carrier tube ( 3 ).
Claim 6
Dependent Claim
76 words
A device as claimed in claim 1 , characterized in that the portion of the plug-in base ( 5 ) plugged into the open end ( 4 ) of the carrier tube ( 3 ) is provided on its outside ( 7 ) with contact ridges ( 8 ) which extend in its longitudinal direction and, upon being plugged into the carrier tube ( 3 ), fit closely against the inner wall ( 17 ) thereof.
Claim 7
Dependent Claim
48 words
A device as claimed in claim 1 , characterized in that the outside diameter of a luminaire tube ( 6 ) which belongs to the side-mounting luminaire and which the plug-in base ( 5 ) adjoins corresponds to the outside diameter of the carrier tube ( 3 ).
