Best Weαe the execution of the invention

Fig. 1 A shows in a perspective view from the front a screw cap 10, here in the form of a spiral twist lock, fixing a door, wall or cover 12, see Fig. 3A, to a frame or housing 14, comprising one in one on the door , Wall or cover 12 disposed aperture 16, see Fig. 2A floating mounted rotary actuator 18 of a rotary closure 10 which is receivable in a fastened to the frame or housing 14 Drehverschlussaufnahmeteil 20. The rotary closure receiving part 20 may be fastened to the frame or the housing by means of screws 22, for example.

The rotary drive 18 has a pinion 24 which meshes with a toothed rod 26 carried or formed by a toothing 28 such that upon rotation of the rotary drive 18, the rack 26 performs a pushing movement in the direction of the bar extension, and that of a pushing movement of the rack 26 of the Rotary drive 18 is rotated by the rack 26. As you can see, that is the rack 26 in several parts and consists of a bearing part 30 and / or at least one rod part 32 and coupling means 34 between the bearing part 30 and rod portion 32nd

The coupling devices 34, which consist here of an outgoing from the bearing part 30 pin 22 on which the rod part is plugged, makes it possible to provide different distances between a first rotary closure 10 and, for example, a second rotary closure 110 and thus a flexible adaptation to attachment points on the cabinet realize, for example, where the rotary closure receiving parts 20, 120 are arranged.

The rack 26 has an elongate slot 36, one elongate side 38 of which forms the serration 28 and whose length is selected such that the rotary drive 18 rotates 90 degrees or alternatively 180 degrees, while the pinion 24 moves from one end of the slot to the other Slit end rolls.

The rotary drive 18 has at its operating end a head with a receptacle 42 for a tool or rotary socket wrench, not shown, on, wherein the pinion 24 is spaced from the lower side 44 of the head 40, so that an annular groove 46 is formed.

The slot 36 may have a second elongated side 48 which is smooth, that has no teeth, and which forms an extension 50 in the central region of its longitudinal extension, which is a passage of the shaft portion 52 of the rotary drive 18, to which the pinion 24 is rotationally rigid pushed and can be held with a lock washer 54 allows. The two non-extended areas of the two sides of the slot are received by contrast of the annular groove and do not require the extension.

In order to achieve a particularly good guide on both sides of the slot, it is advantageous if the toothing of the slot 36 springs back. To reduce the frictional forces, it is favorable if the head 40 with its receptacle 42 runs in a sunk-in disk region 56.

The rotary closure according to the invention can be used particularly favorably if the rotary closure represents a spiral closure. The rotary spiral closure is shown in Fig.2B and provided without pinion. The spiral shutter consists of an actuator with an end 58 which has the shape of a spiral. In a disc-shaped bearing with depression of the head is mounted and the shaft passed through the opening 16 in the plate 12, wherein the operation with the spiral 58 is held axially by a locking ring 54. The receptacle 20 forms an inlet surface in a spiral shape, which receives the spiral 58 of the actuator and thereby attracts the door 12 to the frame and centered.

The spiral, provided for ^Λ A or V ₂ rotation rotary closures are arranged individually arranged, with the disadvantage that the closures must be operated individually. On the other hand, the arrangement according to the invention has the advantage that it can be used not only as a one-point closure, but also as a multi-point closure allows an application with high compressibility, this training consists of at least one closure and, if necessary, coupling elements of other closures. As required, the rotary movement (closing operation) is transmitted from coupling rod 32, pinion 24 and rod drive 18 to further closure points.

In this case, Fig. 2B illustrates an arrangement as a one-point closure, while Fig., 2A represents a multipoint closure arrangement, which is still expandable at the top and bottom.
