Locking and regulation device for panels and slabs

Abstract

A locking and regulation device for preferably made of glass panels and slabs ( 12 ) comprises a U-shaped extruded profile ( 10 ), inferiorly fixed, via locking means ( 11 ), to a reference surface ( 15 ) and which houses, within the central seat ( 14 ) of the U, at least one of said panels or slabs ( 12 ); wherein within said central seat ( 14 ), between the plate ( 12 ) and the extruded profile ( 10 ), is inserted at least a shaped sleeve ( 13 ), which is tapered at the upper end of said seat ( 14 ) which is flanked by and in contact with said panel ( 12 ). In particular, between the tapered portion ( 13 A, 13 B) of said sleeve ( 13 ) and at least one inner wall of said extruded profile ( 10 ), is inserted a wedge ( 16 ), fixed to a respective adjusting screw ( 17 ) arranged in a direction perpendicular to said reference surface ( 15 ) and passing through the wedge ( 16 ) and the sleeve ( 13 ).

1 . A locking and regulation device for preferably made of glass panels and slabs ( 12 ), comprises a U-shaped extruded profile ( 10 ), inferiorly fixable, via locking means ( 11 ), to a reference surface ( 15 ) and which houses, within said U central seat ( 14 ), at least one of said panels or slabs ( 12 ), wherein, within said central seat ( 14 ), between said at least one plate ( 12 ) and said extruded profile ( 10 ), is inserted at least a shaped sleeve ( 13 ), which almost completely fills said seat ( 14 ) in correspondence with a lower part of said seat ( 14 ) and which is tapered at the upper end of said seat ( 14 ), so as to form at least a tapered portion ( 13 A,  13 B) which is flanked by and in contact with said panel ( 12 ), characterized by the fact that, between said at least one tapered portion ( 13 A,  13 B) of said sleeve ( 13 ) and at least one inner wall of said extruded profile ( 10 ), is inserted at least one wedge ( 16 ), connected to a respective adjusting screw ( 17 ), arranged in a direction perpendicular to said reference surface ( 15 ) and passing through said wedge ( 16 ) in correspondence of said upper part of said seat ( 14 ) and coupled to said sleeve ( 13 ) at said lower part of said seat ( 14 ). 
     
     
         2 . Locking and regulation device according to  claim 1 , characterized in that said adjustment screw ( 17 ) connects said wedge ( 16 ) to a lower portion of said sleeve ( 13 ) by fixing means ( 18 ), said wedge ( 16 ) being spaced by said lower portion of said sleeve ( 13 ). 
     
     
         3 . Locking and regulation device according to  claim 1 , characterized in that at least an upper portion of said adjustment screw ( 17 ) is constrained to said wedge ( 16 ) by means of an abutment ( 19 ) which fits in a suitable seat or recess ( 20 ) of said sleeve ( 16 ). 
     
     
         4 . Locking and regulation device according to  claim 1 , characterized in that said adjustment screw ( 17 ) is provided with a head ( 21 ), accessible from the outside of said profile ( 10 ), to make an adjustment of inclination of said plate ( 12 ). 
     
     
         5 . Locking and regulation device according to  claim 4 , characterized in that said head ( 21 ) of the adjusting screw ( 17 ) is incorporated within said wedge ( 16 ). 
     
     
         6 . Locking and regulation device according to  claim 1 , characterized in that said sleeve ( 13 ) is U-shaped and houses centrally said panel or plate ( 12 ). 
     
     
         7 . Locking and regulation device according to  claim 1 , characterized in that said sleeve ( 13 ) and said wedge ( 16 ) are made of resilient and/or yielding material, while said extruded profile ( 10 ) is made in steel and/or aluminum. 
     
     
         8 . Locking and regulation device as to  claim 1 , characterized in that said adjustment causes a displacement in the vertical direction (K) of said wedge ( 16 ), whose slanted wall is thus forced to slide on a respective slanted wall of said at least one tapered portion ( 13 A,  13 B) of said sleeve ( 13 ). 
     
     
         9 . Locking and regulation device according to  claim 1 , characterized in that said at least one plate ( 12 ) rests directly, at a lower end thereof, on said extruded profile ( 10 ) and said sleeve ( 13 ) is made up by two symmetrical pieces, placed on one side and the other of said plate ( 12 ) and maintained in position within said central seat ( 14 ) via a first tooth ( 23 ), formed on a lower portion of said sleeve ( 13 ), which engages on a second tooth ( 24 ) formed on said extruded profile ( 10 ), which can hold said lower portion of each sleeve ( 13 ) during said adjustment.
