Abstract:
Joint for the angular connection of a pair of hollow profile members ( 50 ) having an angular configuration corresponding to the angle of the assembled profile members ( 50 ) and comprising a slide base portion ( 2, 2′, 2 ″), a sheet metal portion ( 1, 1 ′) superimposed thereupon and a bolt ( 5 ) passing through the sheet metal portion ( 1, 1 ′) and screwed into a nut ( 4 ) mounted onto the base portion ( 2, 2′, 2 ″), wherein tightening of bolt ( 5 ) pushes upwardly extending surfaces on either side of portion ( 1, 1 ′) whereby their sharp edges indent the walls of the hollow profile members being connected. The indentation and efficient angular connection of the hollow profile members is enhanced through: a) forming of the sharp edges of the sheet metal to align an aberrant edge thereof in an indentation appropriate direction, b) appropriately orienting the sheet metal portion ( 1, 1 ′) to comply with a set of predetermined geometrical parameters and c) selectively employing varying embodiments of the slide base portion to obtain rapprochement of the points of indentation of the walls being indented.

Claim (Index 10):
Method of use of the joint of the above  claim 1  for the angular connection of hollow profile members ( 50 ) intended to form door/window profile frames and the like, the method comprising the following steps:\n a. Cutting the edges of the hollow profile members ( 50 ) adapted to being angularly connected at an angle having half the value of an intended angle of connection thereof, a plane of symmetry (xx\u2032) passing through the plane of matching contact of said hollow profile members ( 50 ) being connected, and drilling of a hole ( 51 a,b ) comprising a first half hole ( 51 a ) being located centrally along the edge of a chamber ( 53 a ) of a first one of the hollow profile members ( 50 ) being connected and a second half hole ( 51 b ) being located centrally along the edge of a chamber ( 53 b ) of a second one of the hollow profile members ( 50 ) being connected, wherein said hole ( 51 a,b ) is adapted to receiving a key ( 51 ) used for tightening a bolt ( 5 ) provided along said plane of symmetry (xx\u2032); \n b. Selecting a slide base portion ( 2 ) or ( 2 \u2032) with or without an additional base raising member ( 3 ) appropriately corresponding to the width of the chambers ( 53 a ,  53 b ) of the hollow profile members being connected or of a base portion ( 2 \u2033) in combination with a sheet metal portion ( 1 ) or ( 1 \u2032) and performing assembly of the joint through driving of the bolt ( 5 ) through a through hole ( 10 a) of the sheet metal portion ( 1 ) or ( 1 \u2032) and screwing the same into the nut ( 4 ) mounted onto the slide base portion; \n c. Introduction of a first half of the assembled joint into the chamber ( 53 a ) of the first one of the hollow profile members ( 50 ) being connected; \n d. Bringing the chamber ( 53 b ) of the second one of the hollow profile members ( 50 ) being connected into matching contact with chamber ( 53 a ) of the first one of the hollow profile members ( 50 ) being connected and inserting the second half of the assembled joint that projects outwardly from chamber ( 53 a ) into the chamber ( 53 b ), whereby a matching contact of said first and second hollow profile members ( 50 ) is obtained and the hole ( 51 a,b ) is being formed through abutment of matching half holes ( 51 a ) and ( 51 b); \n e. Inserting the key ( 51 ) through the hole ( 51 a,b ) and rotation thereof for screwing the bolt ( 5 ) into the nut ( 4 ) until said upwardly bent parts ( 13 ) of the sheet metal mobile portion ( 1 ) or said upwardly bent parts ( 13 - 14 - 15 ) of the sheet metal portion ( 1 \u2032) impact and indent the walls of chambers ( 53 a ,  53 b ) thereby providing a firm connection of the hollow profile members ( 50 ) and alignment of the joint due to its symmetrical arrangement on either side of the plane of symmetry (xx\u2032).
