(129) The FIG. 1a)-1c) show in a front, side and top view a first embodiment of a clamping and holding device 10 for connecting a profile 12 such as a square profile on a second profile 14 such as a T profile preferably hanging from a ceiling (not shown) and running transversely to the first profile. A left image half of the figures shows the clamping and holding device 10 in an assembled state and a right image half of the figures shows the clamping and holding device 10 in a pre-assembled state.

(130) The holding device 10 comprises a clamp 16 shown in the FIG. 2a)-2f) in different views in partial section. The clamp 16 comprises two shanks 18, 20 that can be adjusted to one another and that can be fixed by end sections 22, 24 to an upper, preferably square ceiling-side section 26 of the second profile 14. Preferably rectangular recesses 28, 30 are provided in the shanks 18, 20 in which recesses the square profile is received in the longitudinal direction.

(131) According to the invention the clamping and holding device 10 comprises a closing sheet 32, 33 that cooperates with the shanks 18, 20. The closing sheet 32 is shown in the FIG. 3a)-3e) in a first embodiment in different views. Stops 34, 36, 38, 40 are provided on the closing sheet 32 along which the shanks 18, 20 can be moved by a screw element 42 such as a threaded pin running vertically or substantially vertically. The screw element 42 is received in a section 43 connecting the shanks 18, 20 and located in a threading 45 and the screw element runs substantially parallel to the shanks 18, 20.

(132) Sections 44, 46, 48, 50 project from the shanks 18, 20 and cooperate with the stops 34, 36, 38, 40 and cross the shanks 18, 20 pivot towards one another for a positive connection with the section 26 of the second profile during the rotation of the screw element 42 against the first profile 12.

(133) In the pre-assembled state (right image half of the FIGS. 1a)-1c)) the first profile 12 extends through the recesses 28, 30 of the clamp 16. The closing sheet 32 is received in the recesses 28, 30 of the shanks 18, 20 and is arranged between the first profile 12 and the section 26 of the second profile 14.

(134) In this state the projecting sections 44, 46, 48, 50 do not yet rest on the stops 34, 36, 38, 40 and the shanks 18, 20 have a straight course.

(135) The clamp 16 moves in the direction of the arrow 54 by rotating the threaded pin 42 in the threading 45, wherein the projecting sections 44, 46, 48, 50 of the shanks 18, 20 are loaded with force against the stops 34, 36, 38, 40 of the closing sheet with the consequence that at least the lower sections of the shanks 18, 20 pivot toward one another in order to enter into a positive connection with the section 26. In this position the first profile 12 is loaded via the threaded pin 42 against the closing sheet 32 with force, while the second profile 14 with the section 26 is positively grasped by the ends 22, 24 of the shanks 18, 20 and rests loaded with force against the closing sheet 32.

(136) Consequently, a vertical movement (rotation of the threaded pin 42) in the direction of the arrow 54 is converted into a horizontal movement (pivoting of the shanks 18, 20) in order to make possible the positive connection of the shanks with the section 26.

(137) In order that the closing sheet 32 is fixed in a pre-manufactured state of the holding device 10, i.e., when the closing sheet 32 extends through the recesses 28, 30 of the shanks 18, 20 and therefore a simple insertion and/or simple handling is ensured, it is provided that stud-shaped projections 56, 58, 60, 62 start from the shank in order to fix and limit the closing sheet 32 in an area between an upper, ramp-like edge of the projecting sections 44, 46, 48, 50 and the stud -shaped projections 56, 58, 60, 62.

(138) FIGS. 4a) to 4e) show the closing sheet 33 in a second embodiment in different views, wherein the same features are provided with the same reference numerals.

(139) The closing sheet 33 differs from the first embodiment of the closing sheet 32 in that two opposite webs 65, 67 extend parallel to or substantially parallel to the stops 34, 36, 38, 40 along a center line 63 of the closing sheet, as a result of which a support width for the section 26 of the T profile bar 14 is enlarged. This simplifies the assembly of the clamping device since the clamping device can be reliably placed in the pre-assembled state along the center line 63 onto the ceiling-side section 26 of the T profile 14.

(140) The FIGS. 5a) to 5c) show a second embodiment of a clamping device 64 with which the first profile 12 can be connected at a distance to the second profile 14.

(141) The clamping device 64 comprises a clamp 66 that is shown in partial sections in the FIGS. 6a) to 6f) in different views. The clamp 66 comprises two shanks 68, 70 that can be adjusted relative to one another and that can be fixed by in sections 72, 74 to the upper, ceiling-side section 26 of the second profile 14. Preferably rectangular recesses 76, 78 are provided in the shanks 68, 70 in which recesses the square profile is received in the longitudinal direction.

(142) According to the invention the clamping device 64 comprises a closing sheet 80, 81 that cooperates with the shanks 68, 70.

(143) The FIGS. 7a) to 7e) show a third embodiment of the closing sheet in different views. The closing sheet 80 is constructed to be substantially U-shaped with lateral shanks 84, 86 connected to one another by a section 88. The section 80 comprises stops 90, 92, 94, 96 that are formed by recesses in edge areas of the section.

(144) Edge-side ends 98, 100 of the shanks 84, 86 form a a first support that rests against a bottom of the first profile 12 while a bottom 102 of the section 88 forms a second stop that rests on an upper side of the section 26 of the second profile 14. The interval between the first profile 12 and the second profile 14 can be defined by the length of the shanks 84, 86.

(145) The clamp 66 can be moved by a vertically or substantially vertically running screw element 104 such as a threaded pin transversely to the longitudinal direction of the first profile 12 and relatively to the closing sheet 80. The screw element 90 is received in a section 106 in a threading 108 and connecting the shanks 68, 70 and runs substantially parallel to the shanks 68, 70.

(146) Sections 110, 112, 114, 116 project from the shanks 68, 70, cooperate with the stops 90, 92, 94, 96 and cause the shanks 68, 70 to pivot toward one another for a positive connection to the section 26 of the second profile during the rotation of the screw element 104 against the first profile 12.

(147) FIGS. 8a) to 8e) show the closing sheet 81 in different views in a fourth embodiment, wherein identical features are designated with identical reference numerals. The closing sheet 81 differs from the closing sheet 80 in that webs 119, 121 are arranged opposite one another along a center line 117 running parallel or substantially parallel to the stop surfaces 90, 92, 94, 96 in order to enlarge a support surface or support width of the closing clamp on the ceiling-side section 26 of the T profile 14.

(148) FIGS. 9a) to 9c) show a third embodiment of a clamping and holding device 118 with a third embodiment of a clamp 120 and a third embodiment of a closing sheet 122.

(149) FIGS. 10a) to 100 show the clamp 120 in different views, wherein the FIG. 10a) shows a front view in partial section, FIG. 10b) a side view sectioned along the section line B-B, FIG. 10c) a bottom view in partial section along the section line C-C, FIG. 10d) a top view and FIG. 10e) a lateral view from the left. FIG. 10f) shows a detail of a stud-shaped projection 60 for fixing the closing sheet.

(150) The clamp 120 differs from the clamp 16 according to FIG. 1 in that sections 128, 130, 132, 134 projecting from shanks 124, 126 do not project from an inner edge of recesses 136, 138 but rather from an outer edge 140, 142, 144, 146 of the shanks 124, 126.

(151) FIGS. 11a) to 11e) show different views of the closing sheet 122, wherein FIG. 11a) shows a front view, FIG. 11b) a side view from the left, FIG. 11c) a side view from the right in partial section along the section line A-A, FIG. 11d) a bottom view and FIG. 11e) a top view.

(152) The closing sheet comprises a recess 150 forming an inner frame 148 in which the clamp is received in such a manner that that it can move longitudinally. A rotary movement of a screw element 154 received in section 150 in a threading 152, which section connects the shanks, in the direction of the arrow 156 against the first profile caused a relative movement of the clamp against the closing sheet. As a result, the sections 128, 130, 132, 134 come in contact with their ramp-like edge with the inner frame 148 of the closing sheet. The inner frame 148 forms a stop, so that a furthermore adjustment of the clamp causes the shanks 124, 126 to move toward one another.

(153) The fifth embodiment of the closing sheet 122 is constructed with reinforcement ribs 158, 160, 162, 164 on its edge. The closing sheet 122 is preferably constructed as a shaped part, especially as a stamped part, wherein the reinforcement ribs 158, 160, 162, 164 are bent at a right angle out of the flat material.

(154) The FIGS. 12a) to 12c) show a front, side and top view of a fourth embodiment of a clamping device 166 with a fourth embodiment of a clamp 168 and a sixth embodiment of a closing sheet 170.

(155) FIGS. 13a) to 130 show the clamp 168 in different views, wherein FIG. 13a) shows a top view, FIG. 13b) a front view in partial section along the section line A-A according to FIG. 13a), FIG. 13c) a bottom view in partial section along the section line C-C according to FIG. 13b), FIG. 13d) a sectional view along section line B-B according to FIG. 13b) and FIG. 13e) a side view from the left. FIG. 13f) shows a detail of a stud-shaped projection 60 for fixing the closing sheet.

(156) FIGS. 14a) to 14e) show the closing sheet 170 in different views, wherein FIG. 14a) shows a front view, FIG. 14c) a side view along the section line A-A according to FIG. 14a), FIG. 14b) a side view from the left, FIG. 14e) a top view and FIG. 14d) a bottom view.

(157) The sixth embodiment of the closing sheet 170 is used if an interval is desired or required between the first profile 12 and the second profile 14, for example, if an adjustment in height is required between the first profile 12 and a suspended ceiling for fitting in a sprinkler system.

(158) The closing sheet 170 is constructed substantially in a U shape and comprises shanks 172, 174 connected to one another by a section 176. A recess 178 for forming an inner frame 180 is introduced in the section 176 by which frame stops 182, 184 are formed. The shanks 172, 174 are bent inwardly toward one another on their end side in order to form first supports 186, 188 that rest against a bottom of the first profile 12. A bottom 190 off the section 176 forms a second support that rests against an upper side of the section 26 of the second profile 14.

(159) A mounting and the clamping take place in a known manner, as has already been previously explained.

(160) FIGS. 15a) to 15c) show in front, side and top views a fifth embodiment of a clamping device 192 for connecting a first profile 12 to a second profile 14 running transversely to the first profile. The clamping device 192 comprises a clamp 194 with two shanks 196, 198 that can be adjusted relative to one another and each with a recess 200, 202 for receiving and fixing the first profile 12 and with an end section 204, 206 for fixing the clamp 194 to the section 26 of the second profile 14 (not shown in FIG. 15).

(161) The clamping device 192 furthermore comprises a closing sheet 280 that cooperates with the shanks 196, 198 of the clamp and that comprises stops 210 that cooperate with sections 212 projecting from the shanks 196, 198 upon a relative movement between the clamping device 194 and the clamp 208 in such a manner that the shanks are moved toward one another. In order to produce a relative movement between the shanks 196, 198 and the closing sheet 208, a screw element 214 is arranged in a section connecting the shanks 196, 198 which element can be supported against the first profile 12 so that a rotation of the screw element 214 crosses the shanks to move toward one another for a positive connection of the end sections 204, 206 to the section 26 of the second profile 14.

(162) The clamp 194 is shown in FIGS. 16a)-16g) in different views. The clamp 192 differs from the embodiments of the clamp 16 according to FIG. 2 and of the clamp 66 according to FIG. 6 in that the end sections 204, 206 resting on the section 26 of the second profile 14 comprise formations 216 on their edges that are preferably stamped longitudinally for stiffening the shanks 196, 198 against bending in the lower area.

(163) The stamped formations 216 extend parallel to side edges of the side sections 204, 206. The shown embodiment of the clamping device 192 is furthermore characterized in that perforations 218 are provided in edge sections of the shanks 196, 198 in a transitional area between the shanks 196, 198 and a section 217 connecting the shanks in order to achieve a purposeful weakening of material in the area of a bending line 220, which makes possible a simplified assembly.

(164) FIGS. 17a) to 17e) show the closing sheet 208 in different views. The closing sheet 208 comprises a base plate 220 in which the stops 210, which cooperate with the sections 212 projecting from the shanks 196, 198, are shaped as recesses, as is shown in the lower view (FIG. 17e).

(165) FIG. 17a shows a top view onto the closing sheet 208. The base plate 220 has transverse edges 222, 224 that run in the assembled state transversely to the longitudinal direction of the first profile 12 and comprises longitudinal edges 226, 228 running in the assembled state parallel to the longitudinal direction of the first profile 12. In order to prevent a lateral tilting away during the assembly of the closing sheet, it is provided that right-angle shanks 230, 232 and 234, 236 extend from opposing, lateral edge sections of the transverse edges 222, 224 which shanks have inner surfaces 238 that rest in the assembled state on an outside surface of the first profile in order to prevent a lateral tilting away, as is shown in FIG. 15b).

(166) According to FIG. 17c) the shanks 230, 232, 234, 236 are bent in such a manner that their ends have a distance K from each other that corresponds to a width K of the clamp 194 so that closing sheet 208 rests on the one hand by the inner surfaces 238 of the shanks 230, 232, 234, 236 on the profile 12 and on the other hand by the inner surfaces 240 of the bent ends 242 of the shanks 230, 232, 234, 236 on the clamp 194.

(167) Furthermore, other shanks 244, 246 extend from the longitudinal edges 226, 228 located oppositely that are constructed shorter in comparison to the shanks 230, 232, 234, 236 and are bent at a right angle to the baseplate 220 and run straight.

(168) The short, straight shanks 244, 246 serve for the inner support of the clamp 194 and prevent the clamp 194 from falling inward during assembly.

(169) FIGS. 18a) to 18c) show a front, side and top view of a sixth embodiment of a clamping device 248 for connecting the first profile 12 to the section 26 of the second profile 14, which section runs at a distance transversely to the first profile (not shown in FIG. 18). The clamping device 248 comprises a clamp 250 with two shanks 252, 254 that can be adjusted toward one another and each with a recess 256, 258 for receiving and fixing the first profile 12 and with an end section 260, 262 for being fixed to the section 26 of the second profile 14.

(170) Furthermore, the clamping device 248 comprises a closing sheet 264 that cooperates with the shanks 252, 254 of the clamp 250. The closing sheet 264 forms stops 266 that cooperate with sections 268 projecting substantially at a right angle from the shanks at a relative movement between the clamp 250 and the closing sheet 264 in such a manner that the shanks 250, 254 are moved toward one another.

(171) In order to produce a relative movement between the shanks 252, 254 and the closing sheet 264 the clamp 250 comprises a screw element 270 that can be supported against the first profile 12, so that the shanks 252, 254 are moved toward one another by rotating the screw element for a positive connection of the end sections 260, 262 to the section 26 of the second profile 14.

(172) The embodiment of the clamping device 248 shown in FIG. 18 differs from the embodiment of the clamping device 192 shown in FIG. 15 in that the section 26 of the second profile is arranged at a defined distance from the first profile.

(173) It is provided for the definition of the distance that the closing sheet 264 comprises two shanks 278, 280 starting from a base plate 272 along edges 274, 276 running transversely to the longitudinal extent of the profile 12 which shanks each form a stop 282, 284 on the upper side on which stop a bottom of the profile 12 can be supported. Furthermore it is provided for a simplified assembly that shank sections 286, 288, 290, 292 extend laterally over the stop 282, 284 and whose inner surfaces rest in the assembled state on an outer surface of the first profile 12 and form a guide in order to prevent a lateral tilting away of the closing sheet during assembly, as is shown in FIG. 18b).

(174) Furthermore, it is provided that shanks 294 are provided bent at a right angle along longitudinal edges of the base plate 272 for the inner support of the clamp 250 which prevents the clamp 250 from falling off during assembly.

(175) Details of the clamp 250 and of the closing sheet 264 are shown in the FIGS. 19a) to 19g) and 20a) to 20e).

(176) FIGS. 21a) to 21d) show an especially preferred embodiment of a clamping device 298 for connecting the first profile 12 to the second profile 14 running transversely to the first profile 12. The clamping device 298 comprises a clamp 300 with two shanks 302, 304 that can be adjusted to one another and with a recess 306, 308 for receiving and fixing the first profile 12. The shanks 302, 304 have an end section 310, 312 for fixing the section 26 of the second profile 14 against the first profile 12.

(177) The clamping device 298 furthermore comprises a closing sheet 314 that cooperates with the shanks 302, 304 of the clamp 300 and has stops 316 that cooperate with sections 318 projecting from the shanks and in the shape of material curvatures upon a relative movement between the clamp 300 and the closing sheet 314 in such a manner that the shanks are moved toward one another, as is shown in FIGS. 21c) and 21d). In order to produce a relative movement between the shanks 302, 304 and the closing sheet 314 a screw element 320 is arranged in a section connecting the shanks 302, 304 which element can be loaded with force against the first profile 12 so that the shanks 302, 304 can be moved transversely to the closing sheet 314 resting on a bottom of the first profile 12 by rotating the screw element. As a result of the relative movement the curvatures 318 come in contact with the stops 320 of the closing sheet 314 and bring about the movement of the shanks toward one another for a positive connection of the end sections 310, 312 to the section 26 of the second profile 14, as is shown in the end position in FIG. 21d). The end sections 310, 312 now lie substantially parallel to side walls of the section 26 of the second profile 14 in order to fix the latter.

(178) FIGS. 22a) to 22e) show the clamp 250 in different views. The clamp 250 is characterized in that, in contrast to the previously described embodiments of the clamp 16, 66, 120, 168, 194, the stops 318 are constructed as material curvatures or stampings in the shanks 302, 304 of the clamp 250. As a consequence, on the one hand a stiffening of the end sections 260, 262 of the shanks 302, 304 into the lower area is achieved and on the other hand a larger support surface of the projecting sections 318 against the stops 316 of the closing sheet 314 is achieved on which the projecting sections 318 slide during the closing. Since no recesses are produced in the inner area of the clamp the lateral guiding of the clamp on the profile is improved.

(179) Another differentiating feature that should be mentioned, especially regarding the embodiments of the clamps 16, 66 is that perforations 322 are introduced in the shanks 302, 304 in the area of the section connecting the shanks 302, 304 and bring about a purposeful material weakening of the shanks 302, 304. This achieves the advantage that during the closing of the clamp 250, i.e., during the moving toward one another of the shanks 302, 304 by the rotary movement of the screw element 320 less expenditure of force is required on account of the lesser bending tension. The result is an elastic and low plastic deformation of the shanks 302, 304 along a bending line 324 which avoids a lateral distortion of the clamp 250.

(180) Curvatures 326 are provided in a vertical direction above the projecting stampings 318. The closing sheet is fixed between the curvatures 326 and the stampings 318.

(181) Furthermore, a purposeful deformation and bending is made possible in the upper area of the shanks 302, 304 along the bending line 324 and with it the maintaining of the provided bending angle.

(182) Furthermore, FIG. 22b), 22d) show that the end sections 260, 262 of the shanks are bent outward at a defined angle before the assembly already so that after the closing the end sections 260, 262 run in parallel without a deformation resulting in the central area.

(183) FIG. 23a), 23e) show the closing sheet 314 in different views. The closing sheet 314 consists of a base plate 328 in whose longitudinal edges 330, 332 recesses are formed for forming the stops 316.

(184) FIG. 23c shows a sectional view along the section line A-A according to FIG. 23a), wherein the base plate 328 comprises two block-outs 338 bent in the direction of a vertical axis 336 that are bent at an angle of approximately 45 to a plane set by the base plate 328. A prismatic centering is formed by the two inwardly located block-outs 338, as a result of which the positioning, i.e., the lateral alignment of the clamp 250 on the profile bar is improved and in addition a clamping is achieved in the lower area after the closing of the clamp 250.

(185) FIG. 24 shows another variant of a clamping device 340 connecting the first profile 12 to the second profile 14 running transversely to the first profile, wherein the second profile 14 is arranged at a distance from the first profile 12. The clamping device 340 comprises a clamp 342 with two shanks 344, 346 that can pivot toward one another and each with a recess 348 for receiving and fixing the first profile 12. Furthermore, each of the shanks 340, 346 comprises an end section 350 for fixing the section 26 of the profile 14, as is shown in the FIGS. 24b) to 24d).

(186) Furthermore, the clamping device 340 comprises a closing sheet 352 cooperating with the shanks 344, 346 of the clamp, wherein stops 354 are formed on the closing sheet that cooperate with sections 356 projecting from the shanks 344, 346 and in the form of curvatures or stampings upon a relative movement between the clamp 342 and the closing sheet 352 in such a manner that the shanks are moved toward one another, as is shown in the FIGS. 24b) to 24d).

(187) In order to produce a relative movement between the clamp 342 and the closing sheet 352 a screw element 358 is arranged in a section connecting the shanks 344, 346 which can be loaded by force against the first profile by rotation so that a rotation of the screw element causes the shanks to move toward one another in order to form a positive connection of the end sections with the section 26 of the second profile 14.

(188) The clamp 342 is shown in FIGS. 25a) to 25e) in different views and substantially corresponds to the construction of the clamp 300 according to FIG. 22 with lengthened shanks 344, 346. Corresponding to the embodiment according to FIG. 22 the shanks 344, 346 also have recesses 362 for the purposeful material weakening of the shanks 344, 346 in order to bring about an elastic and low plastic deformation with a low expenditure of force of the shanks 344, 346 along the bending line 364.

(189) The closing sheet 354 is shown in FIGS. 26a) to 26f) in different views. Lateral shanks 368 extend starting from a base plate 366 whose height defines an interval of the section 26 of the second profile 14 from the first profile 12. The shanks 368 comprise a stop 370 on the end which stop rests on a bottom of the first profile 12 and/or can be supported against it. The shanks 368 together with the base plate 366 form a substantially U shape.

(190) FIG. 26a) shows a top view of the closing sheet 352, wherein recesses are formed in side edges 372 in order to form the stops 354. Furthermore, an inwardly directed curvature 374 is constructed substantially centrally in the base plate in order to reinforce the baseplate.
