The fitting device, here the swing lever lock, covers in the region of each breakthrough 12 respectively. 14 - one on the one, outer side 18 the thin wall 16 to be arranged, the outer edge 20 the breakthrough 12 respectively. 14 Covering headboard, here in the form of the pivot lever 22 receiving trough 24 , from which head or trough 24 a breakthrough 12 respectively. 14 in the mounted position each towering body part 26 emanates. From this body part 26 jump, like 1C represents, towards the outer surface 34 resilient tongues or holding elements 36 before, the free end of an inclined surface 38 for backlash-free support of the body part 26 . 28 on the edge or the edge 40 the breakthrough 12 respectively. 14 the other, inner side 42 the thin wall 16 having.

The from the headboard, here the hollow 24 , outgoing fuselage parts 28 . 32 point against any force of a spring 44 in the body part 26 movable holding elements 36 on, wherein these holding elements after their assembly in the body part by locking locking elements 46 . 48 being held. In the 1B It is shown that the locking elements are hooks hooking each other, wherein the material of these hooks expediently consists of polyamide, that is flexible enough to the linear insertion of the holding elements 36 in the body part 26 . 28 dodge sufficiently and be able to pass each other and spring back according to 1B hooked at the top and bottom, so that they are in the 1B position shown and so from the trough 24 outgoing fuselage parts 32 . 28 . 128 be securely held in the associated Rectangular breakthrough. This fuse can by appropriately strong spring devices 44 be designed so that under normal circumstances and operating conditions, the holding elements or Klipselemente 36 against the force of the spring 44 do not back off.

The closure comprises, as shown here, a behind a Türrahmenabkantung 50 laying forecasting tongue 52 , the two diametrically opposed holding elements 36 . 136 burdened differently. The on the tongue's side 52 in its rear grip position exerted pressure is for the most part of the holding element 36 opposite edge 20 the tipper trough is received while the retaining element 36 is little loaded, which is exactly the opposite on the opposite side, there is this holding element 136 most heavily loaded. To take account of this different load, it may be useful for the particularly stressed clip element 136 from Me tall and not plastic. Since at the same time the less heavily loaded retaining element 36 is made of plastic such as polyamide, this retaining element remains flexible and thus allows the resilient retraction during insertion and against each other locking the two holding elements 36 . 136 ,

While in the embodiment according to 1C the two locking parts 36 . 136 in a parallel to the door leaf plane, in cross-section ratchet cylinder slidably mounted carriage 56 are by a arranged between them latching hook device 46 . 38 against the force of two compression springs 24 , which are on a central wall 58 support, is held in the embodiment according to 3 the arrangement designed such that the holding elements 236 at a distance A to the door leaf level 16 around an axis parallel to the door leaf plane 60 rotatably arranged levers 236 are.

The two levers 236 are at their inner end respectively by a common strong compression spring 244 pushed outward.

By Klipseinrichtungen succeeds to mount the lever lock shown by simply pressing in two suitably designed rectangular openings in the thin wall, by the insertion in the direction of the trough axis 62 lying edges of both breakthroughs 14 . 12 the adjacent inclined surfaces of the holding elements 36 . 136 . 236 against the force of the spring 44 . 144 . 244 press inwards and after reaching the inclined surface 38 let jump back and thus set the trough in the door leaf.

With regard to the construction of the swivel lever closure should be mentioned that the conversion of the pivot lever to the right or left operation, the tongue can be provided with a rotatable cross stop, the at 64 is indicated. Also connected to the trough bar lock body with pinion and rods can be mounted and clipped, especially if the center bar 17 between the two breakthroughs 12 . 14 in the thin wall 16 is omitted and so creates an elongated opening that the breakthroughs 12 . 14 with, see 27 ,

Like from the 1A and 1B shows, the upper body part serves 26 from the hollow 14 protrudes, as a bearing for a drive shaft 66 , At the outside of the door leaf end of the hand lever 22 around an axis perpendicular to the door leaf plane 68 pivoted outward while the inner end of the shaft 66 with a square ends, on the tongue having a square opening 52 attached and by means of a fixing screw 72 is held.

To the bearing block for the shaft 66 closes above and / or below each holding element 28 . 128 at, wherein the holding elements and the bearing block together form the dimensions for the passage through the rectangular opening in the door leaf.

At the bottom of the trough is a receiving area 30 for one of the hand lever 22 outgoing cylinder lock interlocking part, with eccentric moved tongue or thumb 70 provided, behind a return area 74 by pressing a cylinder key 76 can be locked in the folded position.

In order to perform a folding movement and locking with the key removed, is in accordance with 2 alternatively a spring rear handle 174 provided, including the rotating tongue 170 could be mountable by Klipseinrichtungen torsionally rigid on the cylinder roller.

In 4 and below, an embodiment is shown in which the clip fastening according to the invention is applied to a hinge. That's how it shows 4A and 4D a two-part hinge with the hinge parts 80 . 82 , wherein the lower, first hinge part 80 by means of the Klipselement described in connection with the pivot lever handle 228 on the door frame 250 is fixed while the second, upper hinge part 82 with the door leaf by means of the retaining element 232 connected, see 4D ,

The lower hinge part 80 and upper hinge part 82 are through a hinge pin 84 connected to each other in the lower hinge part 80 is firmly caulked while its upper end in a bore 86 of the upper hinge part 82 is received rotatably. Lower hinge part 80 is with a door frame 150 connected, by means of a Klipsbefestigung 228 while the upper hinge part 82 by means of clip fastening 232 a metal door 216 around the hinge axis of the hinge pin 84 keeps pivoting.

The in the door frame 250 or in the door leaf 216 required rectangular opening is, for example, in 13 represented and with the reference number 86 Mistake. Again, the Klipsbefestigung comprises a on the outer side of the thin wall or the frame 250 and the door panel device 216 to be arranged, the outer edge of the breakthrough 87 Covering headboard or hinge lobe 88 , one of which is the breakthrough 87 in the mounted position protruding hull part 228 emanates from the yielding in the direction of its outer surface holding or tongue elements 336 to spring up, whose free End an inclined surface 38 for backlash-free support of the body part 228 and therefore the hinge 80 on the edge of the breakthrough 86 the other, inner side of the thin wall 250 , is arranged. The same applies to the hinge part 82 and the door leaf 216 ,

For attachment of the hinge, a construction can be selected, as has already been described in connection with the pivot lever lock, or as they according to an embodiment of the 5A to 5C is selected. Instead of hooking hook here serves a pin according 6 as a lock. Two metal components according to 5A to 5C be in a rectangular guide channel according to 8B pushed in and by a bolt screwed from the outside according to 6 held in the retracted position, so that they can indeed move a short distance to each other, but can not fall out. This is achieved on the one hand by a return 90 , which is a career for half the pen width of the pen 92 results, and by the coil spring 320 on the one hand in an opening 94 of the part 336 supported, on the other hand on an intermediate wall 358 , The part 90 is formed so symmetrical that it according to the mounting option 8A and 8B allows.

In the 9A . 9B and 9C an embodiment for a hinge is shown in which the one hinge part on the door leaf 416 is welded while the other hinge part on the door frame 450 is held with a further embodiment of the clip fastening according to the invention. This consists of the door leaf level at a distance about an axis perpendicular to the door leaf axis rotatably arranged lever means 436 , which are pressed by spring means to the outside and then edge portions of a door leaf 450 take arranged rectangular opening.

The 10A and 10B show an embodiment in which the two are pressed apart by spring means holding elements are held by hooks to each other, between which an inclined wedge 94 is arranged. A similar construction shows 11 ,

In 12 is a round pen 294 provided, which holds two mutually displaceable, made of hard material such as metal parts in position.

In 13 is a rectangle breakthrough 87 illustrated how it is suitable for the embodiment described here, a lock. So could a hinge element, as in the 14A and 14B is shown in side view and end view, in this rectangular opening 87 be clipped. Otherwise, the structure is similar to that of 3 but this is an (upper) hinge part 282 is.

The 15A . 15B . 16 and 17 are representations of a fixture, in accordance with 15A upper part of a pivot lever, according to 15A lower part of a hinge part can be fixed in a rectangular opening of a thin wall. Here is a single spring provided, both holding elements 536 from the depressed Klipsstellung according to 17 in the clipped position according to 16 pushes when the component or the fitting is pressed into the mounting hole.

The two retaining elements 536 are in the 19A and 19B again as an item in two different views. The 18A and 18B show the associated item as hinges. It is important that here the hook of the retaining element 536 at a wall opening 96 supported. Instead of the above-described solution with central web and two springs, wherein the holding elements hold against each other, a solution is found here, with a spring and end opening in which hold the clip elements with hooks in the assembled state. In the in the 20 . 21 . 22 . 23A . 23B . 24A . 24B illustrated embodiment, which is designed similar to the embodiment according to the 15 to 19 , a lateral in the holding or guide channel is provided instead of the frontal opening. In both cases, the advantage is that you can do with only one spring.

The 16 . 20A and 26B show an embodiment in two different views, in which with the conical screw 98 two retaining elements 736 be pressed apart, resulting in a particularly large holding force, the screw head is located inside and a Blindbefestigung is not possible. But you could also tighten with a screw from the outside a conical nut, which would have the same effect, and also would allow a blind assembly.

25 shows a pivot lever with a, arranged at the bottom, known per se hook attachment, however, provided at the upper end holding elements according to the invention. As according to 25 At the lower end only small forces are effective, a hook attachment by means of hooks 100 while in the tongue area, 52 where the closing forces and the rotation of the hand lever cause greater forces to occur, the inventive device 836 is provided, it is one of the preceding embodiments, it is specifically the embodiment by means of conical screw.

On this way can be depending on the load, choose the optimal mounting method.
