Description

Background of the invention

The invention relates to a compression closure, comprising a closure housing with a drive end and a driven end and with a rotatably mounted between these ends drive shaft having a drive means such as luff wrench or gear at the drive end of the housing, and which housing at the drive end an annular surface about the axis forms the drive shaft.

State of the art

Such a compression seal is from the EP 1 131 521 B1 already known, see for example the local there FIG. 1 ,

Object of the invention

The object of the invention is to provide a compression closure of the type mentioned, which provides a further alternative to the structure of the known closure.

solutions

The object is solved by the features of claim 1. The drive shaft at the output end of the housing carries a journal whose axis relative to the axis of the drive shaft has an angle of approximately 45 degrees, being mounted on the journal of the foot of a rotary latch, which foot forms a circular surface about the axis of the journal, which two annular surfaces frictionally or positively lock each other when the drive shaft is rotated.

The compression seal has the advantage of allowing a relatively large compression margin, depending on the length of the rotary latch.

According to one embodiment of the invention is based on the foot of a bolt which extends at an angle of approximately 45 degrees with respect to the plane of the annular surface of the foot.

According to another embodiment of the invention, the positive rolling is achieved by a toothing of the annular surfaces, preferably with the same number of teeth on the annular surfaces. The positive connection has the advantage of greater stability.

The housing may have different shapes, according to an embodiment of the invention, the housing is a rectangular lock case. In another embodiment, the housing is a substantially circular rotary latch housing. The free end of the rotary latch can form a tongue. Alternatively, the free end of the rotary latch can carry a caster, which is particularly advantageous here to produce the force required for the rotation of the bolt.

According to yet another embodiment, the free end of the rotary latch forms a spring-loaded part spherical surface.

According to yet another embodiment of the invention, the bearing pin is formed by a cap screw.

The bearing pin can also be formed by an integrally formed with the drive shaft approach with locking ring at the free end.

The lock case may guide a rack meshing with a gear which is rotationally rigidly connected to the drive shaft.

The rotary latch can have an adjusting joint between foot and ramp surface.

Finally, it is possible to make the rotary latch cranked between foot and ramp surface.

Best ways of carrying out the invention

Fig. 1A shows a compression closure 10, consisting of a closure housing 12 having a drive end 14 and a driven end 16 and with a rotatably mounted between these ends 14, 16 drive shaft 18, the drive end 14 of the housing 12 has a drive device 20, such as socket wrench or gear, wherein the housing 12 at the output end 16 forms an annular surface 22 about the axis 24 of the drive shaft 18. The drive shaft 18 carries at the output end 16 of the housing 12 has a bearing pin 26 which has an angle of approximately 45 degrees relative to the axis 24 of the drive shaft 18, wherein on the bearing pin 26 of the foot 30 of a rotary latch 32 is mounted, which foot 32 is a circular surface 34th forms around the axis 28 of the journal 26, which two annular surfaces 16, 34 frictionally or preferably, form-fitting rolling on each other when the drive shaft 18 is rotated. In the illustrated embodiment, the housing 12 is conventionally fixed with a screw in a door leaf 36, while the rotary latch 32 engages behind a frame 38. As can be seen, extending from the foot 30 is a latch 32, wherein the latch extends at an angle of approximately 45 degrees with respect to the plane of the annular surface of the foot 30. Due to these angular relationships, it changes the position of the bolt 32, in particular its axis 40. While in the in the Figs. 1A, 1B and 1C shown foot position, the axis 40 is parallel to the plane of the door leaf level 36 (angle 0 degrees), is at the half-open position in the Fig. 1D . 1E and 1F is shown, the angle has grown to about 45 degrees, whereby the cabinet door and cabinet frame can move away from each other.

Finally, in the presentation of the Fig. 1I to 1K reaches the angle of 90 degrees, whereby the door leaf completely free from the door frame.

During this rotation and pivoting movement of the bolt 32, the shaft 18 rotates by 180 degrees, which is exactly half a turn.

In all the illustrated embodiments, a positive unwinding is realized, by a toothing of the annular surfaces 18, 34, wherein preferably the two annular surfaces have the same diameter and the same number of teeth.

At the in Fig. 1A to 1K illustrated embodiments, the free end of the rotary latch 32 carries a caster 42, which has over the casserole the advantage of lower friction and thus contributes to ease of closure operation. The caster 42 is held with a locking ring 44. Likewise, the foot 30 is held on the bearing pin 26 with a locking ring 46 here. The construction is designed so that the closure can be secured by a cap nut 48, which is attachable along the latch and can be screwed onto a peripheral thread 50 of the housing, see Fig. 1A ,

A pin or a grub screw 52 serves as a stop for the movement of the foot and thus the bolt.

In the Fig. 2A to 2H Embodiments are shown in which the compression element is designed as an attachment to a conventional rotary latch. Otherwise the function is the same as already described.

In addition, in contrast to the previously described embodiment, in which the bearing pin 26 is formed by a integrally formed with the drive shaft 22 approach with locking ring at the free end, here a cap screw is provided which forms the bearing pin 126. In Fig. 2G the individual parts can be recognized, consisting of a conventional closure from which the tongue has been removed, see the reference numeral 54. Instead of the tongue, an adapter piece 56 is mounted by means of a countersunk screw 58 into which a drive shaft 118 can be inserted laterally. These components 56, 58 are rotatable for supporting the housing part 116.

In the embodiment according to the FIGS. 3A to 3E the drive shaft 218 carries at its lower end a gear which is mounted in the lock case, which meshes with the likewise mounted in the lock case 212, the movable rack 60. About the driver 62, the rack can drive a locking rod, not shown. Like in the Fig. 3A recognizable, the two parts of the lock housing 212 are held together by screws 64 and nuts 66 and also optionally attached to the door panel 236. The drive shaft 218 can be driven either by the rack 60 or by a socket wrench or by a pivot lever lock or the like, depending on the desired combination of fitting devices.

The screws 64 and the associated nut 66 are guided in openings 68, 70 of the lock case halves so that a certain adjustability is given in the direction of the rack, so that the zero position of the rotary latch can be adjusted with respect to the articulated on the rack locking bar. Larger adjustment options, in particular with regard to the firmness of the closure in the closed position can be realized if, according to the embodiment according to Fig. 4A to 4E the rotary latch 332 between foot 330 and ramp surface 342 has a hinge 72, consisting of two grooved or fluted surfaces 74, 76, which make it possible to clamp this setting after adjustment of the strains by means of a screw 78.

In order to obtain the load of the foot surface 330 exactly at the axial point, the rotary bolt 332 is cranked, see reference numeral 80.

In the embodiment according to Fig. 5A to 5H forms the free end of the rotary latch 432 a spring-loaded, reference numeral 82, part ball surface 84. This results in a self-adjusting H-measure, which is a measure of the pressurization of the seal 86 between door and frame.
