Patent ID: 7624958

Claim:
Fastening block for mounting objects having a mounting rod on a profiled rail ( 12 ) having an at least approximately rectangular cross section, said block comprising: (a) a housing part ( 14 ) with at least one housing-attached first claw ( 26 ), which is intended for overlapping the profiled rail ( 12 ) in such a manner that the housing part ( 14 ) with application surfaces which are parallel to the profiled rail ( 12 ) is applied against at least two surfaces of the profiled rail ( 12 ), (b) an L-shaped movable clamp part ( 28 ) having a first L leg ( 30 ) mounted within the housing part ( 14 ) in a manner so it can be swiveled about a first axis ( 32 ) which is parallel to the application surfaces and it is prestressed in a clamping position, further the movable clamp part comprises a second L leg ( 34 ), said first L leg ( 30 ) and said second L leg ( 34 ) together forming a second claw wherein the second claw is adapted to be applied to the other end of the profiled rail opposed from the first claw, (c) a clamp device ( 40 , 46 , 72 ) in the housing part, the clamp device is mounted on the first leg for clamping and stopping the clamp part ( 28 ) in the clamping position, wherein the clamp device comprises an actuation projection, a pull rod, and a clamping screw, (d) the actuation projection ( 36 ) which is oriented radially to the first axis ( 32 ) and connected to the first L leg ( 30 ) of the clamp part ( 28 ), (e) the pull rod ( 40 ) which is coupled to the actuation projection in a manner so it can be swiveled about a second axis ( 38 ) which is parallel to the first axis ( 32 ), wherein said pull rod extends approximately parallel to the second L leg ( 34 ), (f) the clamping screw ( 72 ), which is coupled to the clamp device to apply tension on the pull rod ( 40 ) to lock the movable clamp part in one position and the clamping screw is movable directly or indirectly on the housing part ( 14 ), said clamping screw ( 72 ) provided with a handle ( 70 ) engaging therein, (g) a clamping sleeve ( 46 ), mounted to the pull rod to guide the pull rod ( 40 ) in a manner which allows it to shift axially in a housing guide ( 48 ) which is coaxial to the pull rod axis, (h) a perforation ( 58 ) in the clamping sleeve which is oriented perpendicularly to an axis of the clamping sleeve, in a section of the clamping sleeve ( 46 ) which extends axially at least partially out of the housing part ( 14 ), (i) the clamping sleeve ( 46 ) further having an axially external end with a coaxial threaded bore ( 68 ) which intersects the perforation ( 58 ).
