Clamping device for connecting profile bars

A clamping device (10, 64, 118, 166, 192, 248, 298, 340) for connecting a first profile (12) such as a square profile to a second profile (14) such as a T profile that runs transversely to the first profile (12), comprising

• a clamp (16, 66, 120, 168, 194, 250, 300, 342) with two shanks (18, 20;
• 68, 70;
• 124, 126;
• 196, 198;
• 252, 254;
• 302, 304;
• 344, 346) that can be adjusted to one another and have a recess (28, 30;
• 76, 78, 200, 202;
• 256, 258;
• 48, 350) for receiving and fixing the first profile (12) and with an end section (22, 24;
• 204, 206;
• 260, 262;
• 310, 312;
• 352) for being fixed to a section (26) of the second profile, and comprising a screw element (42, 104, 154, 214, 270, 320, 360) for moving the shanks toward one another,
• characterized in that
• the clamping device (10, 64, 118, 166, 192, 248, 298, 340) comprises a closing sheet (32, 80, 122, 170;
• 208, 264, 304, 352) with stops (34, 36, 38, 40;
• 90, 92, 94, 96;
• 148;
• 180, 182;
• 212;
• 268;
• 318;
• 358), which closing sheet cooperates with the shanks (18, 20;
• 68, 70;
• 124, 126;
• 196, 198;
• 252, 254;
• 302, 304;
• 344, 346) of the clamps (16, 66, 120, 168, 194, 250, 300, 342), that the screw element (42, 104, 154, 214, 270, 320, 360) starts from a section connecting the shanks and can be supported against the first profile (12) for adjusting the shanks relative to the closing sheet, whereby sections (44, 46, 48, 50;
• 110, 112, 114, 116;
• 128, 130, 132, 134) projecting from the shanks (18, 20;
• 68, 70;
• 124, 126;
• 196, 198;
• 252, 254;
• 302, 304;
• 344, 346) cooperate with the stops and during the adjusting of the clamps (16, 66, 120, 168, 194, 250, 300, 342) the pivoting of the shanks (18, 20;
• 68, 70;
• 124, 126;
• 196, 198;
• 252, 254;
• 302, 304;
• 344, 346) onto one another brings about the positive connection of the end sections (22, 24;
• 204, 260, 262;
• 206;
• 310, 312;
• 352) to the section (26) of the second profile (14).
