Description

The invention relates to a rotary bolt lock with pulling device, consisting of a lock housing that has a socket opening at an outer end and has a rotary bolt at its other, inner end, and that with one End by a breakthrough in adapted to the outer cross section of the housing a wall, such as door leaf, can be pushed through and fixed, with a first, for outer end open to the housing axis coaxial bearing area for one Socket wrench pick-up head, and with one at the first storage area subsequent second open towards the opposite end of the housing Storage area for a rotary bolt bearing, rotatable in the housing area and axially displaceable bolt drive foot, between socket wrench holder and rotary latch a coupling device is provided, the Closure with a cam pin-cam track device for rotation and / or Axial displacement of the rotary bolt with respect to the housing when the Socket wrench holder is provided and between socket wrench holder and rotary latch an angularly limited freewheel is made possible.

State of the art:

Such a rotary latch lock is already known, see DE 35 04 691 C2.

Furthermore, the similarly designed closure arrangement according to the DE 35 02 418 C2 referenced.

US Pat. No. 2,269,264 is also of interest.

All three known closures worked in such a way that when actuated to Lock the bolt or sash first turned to the door closing position becomes, which usually means a rotation by 90 °, whereupon with further rotation a pulling movement of the actuating handle takes place, in which the bolt in the direction of the rear surface is pulled so as to have a pressing force between, for example, the To reach the door and the door frame. This combined rotation and Axial movement is achieved by cam pin-cam track devices, which at the DE 35 02 418 C2 is arranged in the handle lever area, while in DE 35 04 691 is shifted into the interior of the lock housing, in the form of a between the lock housing on the one hand and the shaft carrying the bolt on the other hand, arranged sleeve, in the axially and obliquely extending slots are arranged, in which the ends of a cam pin slide, which as a cross pin in the shaft carrying the bolt is held. This is missing in US Pat. No. 2,269,264 Housing, instead is an actuating shaft 21 with an actuating head 22 in a holding plate riveted to a flap 13 which can be suspended in a frame 10 15 rotatably held. The holding plate 15 forms stops 18 and guides 16 for a bolt (sash) 23 by a socket provided with cam tracks 28 24 is worn. The end facing away from the actuating head 22 Actuating shaft 21 carries in cam tracks 28 sliding cam pins 28, under the Pressure of a spiral spring 29 arranged between the holding plate 15 and the bar 23.

A disadvantage of the prior art is the complicated structure, which leads to increased Manufacturing costs and cumbersome assembly work leads. So includes for example the closure according to DE 35 04 691 C2, see Fig. 2, a with Flanged lock housing, which with two screws (alternatively with one Union nut) can be mounted in a wall, one by a snap ring in the Socket wrench holding head, one rotatable and slidably mounted bolt drive foot carrying the rotary bolt, the Latch is fixed on this foot by means of two nuts, a pin which is passed through the Foot is passed transversely and with its ends in the cam tracks one complicated to be produced separately by punching sleeve is in turn arranged within the housing and rotatable with the receiving head is coupled. Finally, there is a compression spring that follows the shaft presses on the outside, i.e. to the open position.

This means that the arrangement of ten known from DE 35 04 691 C2 there are sometimes complicated parts to manufacture.

The closure known from US-PS 2,269,264 takes up a lot of space, is against Pollution unprotected because there is no housing, and the attachment of the Holding plate on the flap requires laborious riveting.

The object of the invention is to provide a rotary bolt closure at the beginning mentioned type, which consists of significantly fewer and easier to manufacture parts, is cheaper to manufacture and easier to assemble.

The task is solved in that a cross section of the socket head round shaft that extends beyond the bolt drive foot and on the protruding end with a cross hole for receiving a cam pin is provided, and that from the side facing away from the housing of the bolt Cam track is formed, on which the cam pin is guided against spring force, and that the outer circumference of the bolt drive foot has a non-circular cross-section has and in a likewise non-round cross-section breakthrough in a first section of the second bearing area axially displaceable and in one second section of the second storage area is rotatable to a limited extent. Such The arrangement has significantly fewer parts, for example only six parts cheaper to manufacture and easier to assemble. The cam track is outside and can be injection molded in simple injection molds. The through the Storage area sections is particularly simple coupling device compared to e.g. the arrangement in the US-PS 2,269,264 smaller and is protected in Casing. The rotatability is preferably limited to approximately 90 °.

It is advantageous if the non-round cross section of the bolt drive foot in Cross section represents a parallelogram with rounded corners.

The non-circular cross section of the breakthrough in the second section of the second Storage area can consist of two opposite circular sections that through two mutually parallel side walls or through in the lumen of the Breakthrough penetrating nose areas are interconnected.

With regard to the housing, it is favorable if the housing is or partition is divided into the first and second storage areas, which Partition has a circular breakthrough for the passage of the shaft, which from Socket wrench pick-up head penetrates the bolt drive foot. To this This avoids the use of a snap ring.

According to yet another further development, the Socket wrench holder with a rear ring shoulder on the partition.

In the second storage area, a spiral compression spring is supported on the one hand Partition, on the other hand on the end face of the bolt drive foot.

It is particularly favorable if the rotary latch forms a reinforcement wall that the Circularly surrounds the cam track and the cam pin slides out prevented. Then there is no need to fix the cam pin by means of a press fit Disassembly, as well as assembly, made it much easier.

The rotary latch can form a constriction directed towards the housing, which Introduce the tongue of the rotating latch including the assembled housing, i.e. the Completely assembled closure through an opening in a thin wall (and if necessary pushing on a union nut). This is also a Feature that significantly facilitates assembly, since already assembled Quarter-turn locks can be mounted in a thin wall.

Such a rotary latch is particularly advantageous if the Rotary bolt lock consists of a lock housing, which on one, outer end has a flange, and that with its other inner end through a breakthrough adapted to the outer cross section of the housing in a thin wall, such as door leaf, until the flange abuts the wall can be pushed through and by means of a union nut, plug spring or the like in this position is attachable.

Alternatively, a rotary bolt lock is also conceivable, which has a lock housing has, at the other (inner) end a flange or mounting boss has, and with its other (outer) end by one to the External cross section of the housing adapted breakthrough in a thick wall, such as Door leaf or flap until the flange or shoulder comes into contact can be pushed through and in this position by means of retaining washers and / or screws is definable.

According to yet another embodiment of the invention, the rotary latch can be close have a free end of a thread for receiving a set screw whose Head forms an adjustable rotary bolt contact surface. This enables an additional Depth and contact pressure setting.

According to a still further embodiment of the invention, the rotary bolt closure comprises a to the housing or frame or the like Grip area for the rotary latch forms. Such a rotary latch lock can be advantageously in the free space between, for example, the frame and the door fold accommodate.

The bolt receiving part preferably forms two diametrically opposite one another Behind grips. This has the advantage that the rotary latch has a gag shape can, as is provided according to another embodiment of the invention, which advantageously allows that when closing the door this lever-like After 90 ° rotation, the locking bolt is tilted into the one attached to the frame Latch receiving part sets and the door z. B. aligns in height. After a The lever-like locking part or tongue becomes a further 90 ° rotation dressed.

The big advantage compared to conventional twist locks, where with the rotational movement of the bolt ("sash") in the closed position also the Pull-out movement in the direction of the axis of rotation takes place (e.g. by chamfering the Ramp surfaces of the bolt, see e.g. B. the step tongue according to catalog page 1-2000 the catalog of the company DIRAK from 1996 or according to EP 0058931) and thereby the door leaf perpendicular to the door frame due to frictional forces is shifted to the axis of rotation and warped, the exact alignment is already at Start of the closing process.

Best ways of carrying out the invention :

1 and FIG. 17 show a rotary bolt closure 10 in an axial sectional view, 110 with a traction device to be explained in more detail, the Twist lock closure consists of a closure housing 12, 112, which on its one end has a flange 14, 114 and the other end and from further devices emerging from this end, namely the rotary latch 18, 118, through a to the outer cross section of the housing (e.g. around each with Flats offset by 90 °, as can be seen, for example, in FIG. 4B) adapted opening in a wall, such as door leaf 20 or wall lock flap 120 insertable and by means of a union nut 22, plug spring, cap screws 125 (as in the prior art), retaining springs protruding from the housing wall, or similar facilities can be determined in this position. In the case of FIG. 1 illustrated embodiment, see also FIG. 4B, a union nut 22nd used, which is applied to an on the outer surface of the housing 12 External thread 24 is screwed on. To secure the housing against rotation within the Wall 20, the housing has at least one flat 26, which with a corresponding tendon-like narrowing of the associated breakthrough in the Wall 20 works together and so a rotation lock of the housing within the Breakthrough. Appropriately, four are each at 90 ° to each other staggered flats 26 are provided so that the housing 12 in four To be able to install positions rotated by 90 °. Accordingly, even then the breakthrough in the wall 20 such four tendon-like constrictions exhibit.

4A, or FIGS. 10C and 10D, the housing 12, 112 each has an axial Sectional view of the housing, one open to the flange 14, 114, to Housing axis coaxially arranged bearing area 28, 128, in which the Recording head 30, 130 (see also Fig. 5 and 12A, 12B) for receiving a Actuation of how socket wrench 32 fits. At this first storage area 28, 128 in the Housing 12, 112 connects to a second storage area 34, 134, the one that Rotary latches 18, 118 carrying and axially displaceable in the housing area mounted bolt drive foot 36, 136 receives.

From the head 30, 130 a shaft 38, 138 with a round cross-section originates through a corresponding round bore 140 in one of the two bearing areas 34, 134 and 28, 128 separating partition 42, 142 and then through a Appropriate bore 44, 144 in the bolt drive foot 36, 136 passes through and on forms a transverse opening 46, 146 at its end through which a cam pin 48, 148 is stuck through with its ends on a (duplicate) Cam track 50, 150 supports the on the outward-facing surface around the Bore 44, 144 of the rotary latch 18, 118 is formed around. The bolt drive foot 36, 136 has a non-circular peripheral surface 52, 152, which according to FIG. 3B consists of a Parallelogram, i. H. from two mutually parallel surfaces 54, 56 and 58, 60 exists, which form an angle 62 other than 90 °, and their Connection corners are rounded, which cross-section in one of the storage area 34, 134 formed non-round opening 35, 135 not rotatable, but only axially 9A, 9C, and in one of the end wall 64, 164 of the The rear end 61, 161 of the housing 12, 112 formed opening 66, 166 in this way fits that in this position of the foot 36, 136 in the housing 12, 112, see 9C and 9E, a rotation of z. B. 90 ° is made possible. To this end the opening 66, 166 could consist of a circular opening divided by two tendon-like constrictions 68 is narrowed. 4C and 10B show another Embodiment in which the cross section of the peripheral surface 152 is slightly different, namely is designed wider at the longer ends, correspondingly is the shape of the Breakthrough 166 is essentially a circular shape, with two opposing cam-like projections 167 on which the cross section 152 in the two by 90 ° end positions lying apart.

This shape enables the housing 12, 112 at its end 64, 164, the Bolt drive foot in its position shown in FIGS. 9C, 9E between housing 12, 112 and tongue 18, 118 a rotational movement of 90 °, between one Position, as shown in Fig. 1 or Fig. 17, and a perpendicular thereto Position of the rotary latch 18, 118.

The cam track 50, 150 clearly recognizable in FIGS. 3C and 11E, 11F has one highest point 70, 170, which can also be seen in broken lines in FIG. 4, in which Position of the cross section 48 on the one hand strikes an edge 72, 172 and therefore further movement along the cam wall is prevented, on the other hand in one small trough, so as to have a stable rest position, such that a movement from this position, namely in the direction of arrow 74 a certain one Initial force is required before the pin 48, 148 along the cam curve 50, 150, moves down, for example by a stroke of z. B. 6.5 mm until its deepest Position is reached in which the pin has reached a stop surface 76, 176, wherein the two stop positions 72, 172 and 76, 176 the pin preferably one Allow 90 ° rotation.

A spiral compression spring 80, 180 arranged in the second bearing area 34, 134 supports depends on the one hand on the intermediate wall 42, 142 of the housing 12, 112, on the other hand presses it against the end face 82 of the bolt drive foot 36, 136, which in turn the rotary bolt 18, 118 with its cam track 50, 150 against the transverse pin 48, 148 suppressed.

The arrangement therefore works as follows: starting from the one shown in FIG. 17 shown closed position of the twist lock is first the key 32 is inserted into the receiving head 30, 130 and the key 32 then rotated counterclockwise. After overcoming a little resistance (Lifting the cam pin 48, 148 from the one in FIGS. 3A and 11F, for example recognizable small trough), d. H. Moving the tongue 18, 118 against the force of the Spring 80, 180 by about 0.5 mm then slides down the cam or the pin 48, 148 along the arrow direction 74 until reaching the Anchor point 76, 176, during which movement due to the pressure of the Spring 80 of the bolt 18 to the outside by the stroke of, for example, 6 mm moves without being able to turn inside the housing. Only in the z. B. 18 recognizable position, the cam or the pin 48, 148 which abuts the edge 76, the bolt 18, 118 rotating with and thus rotates the bolt drive foot 36, 136 from the z. B. recognizable in Fig. 4B a stop position in a 90 ° shifted, second stop position. The rotary bolt is now in a position 90 ° with respect to FIG. 1 moved and around the stroke of z. B. 6 mm raised, dashed position, which is designated in Fig. 1 with 11. The closing process takes place in the reverse Direction, d. that is, it is rotated clockwise, initially after rotation the position of the bolt drive foot 36 shown in FIG. 4B is reached by 90 °, whereby further rotation of the bolt drive foot is prevented by the housing becomes. By hitting the edges 52 and 152 on the corresponding Breakthrough walls of the breakthrough arranged in the end wall 64 in the housing 12 the rotary bolt 18 can no longer rotate with its bolt drive foot, so that with further rotation of the actuating key only the shaft 38 remains keep turning, d. that is, the pin 48 at the top of this shaft 38 against the Arrow direction 74 slidably moves from a lowest point to a highest point while sliding the bolt 18 along the cam surface by the stroke presses down until the rotary latch 18 shown in solid line in Fig. 1 Has reached position. In this position, the bolt 18, 118 presses against one of for example, a cabinet housing 21, 121 formed rear engaging surface 23, 123 and thus holds the door leaf 20, 120 in an adjacent to the door frame 21, 121 closed position.

The advantage of this mode of operation is that the rotary movement of the bolt 18 takes place as long as there is no contact with the rear grip 23, or as long as this contact is still loose. The bolt is only tightened when the closed position is reached and thus the final sealing (contact is under pressure).

It should also be added that a wall 84, 184 of the rotary latch 18, 118 that the in Fig. 1 and 17 recognizable cam track 50, 150 encloses in a circle, see also Fig. 3C and Fig. 8, so that the pin can be inserted loosely in the transverse bore 46, 146 without that there is a risk that it will fall out. Around the pin for initial assembly It is only necessary to introduce the rotary latch 18 via that shown in FIG. 2 Position against the force of the spring 80 by a stroke 86 of 4 mm, for example press further so that the bore 46 comes free from the wall 84 and the pin 48 can be inserted. This position is not in normal operation reached so that a backup of the pin in its during normal operation Bore 46 is guaranteed. 8, the stroke dimension is reduced by Arrangement of a depression 119 which in the upper end face of the wall 184 at a Suitable location is arranged and the pin 148 in that shown in Fig. 8 Contribution allowed.

Furthermore, it should be pointed out that the latch 18 has a constriction 88 has its side facing the flange 14. To insert the 2 in an opening with a cross-sectional area according to the cross section of the housing 12, the tongue then does not need to be dismantled become.

In addition, there is a defined contact surface area 90 on the rear grip surface 23rd

Fig. 7 leaves an alternative in an exploded side view Recognize the embodiment of a rotary bolt lock 110 with a pulling device, wherein the twist lock closure 110 consists of a closure housing 112 which has a flange 114 at one end and with at the other end emerging further devices, namely the rotary latch 118 is equipped. Here too, the outer cross section of the housing is offset by 90 ° Flats 126 on, so four different by 90 ° to each other To enable assembly positions, as already described. When mounting in one thin wall can be attached in the same way as it is shown in FIG. 1, or alternatively, for a thick wall, as shown in FIG. 17. There is the housing with its flange 114 from behind through a Breakthrough opening 111 of a relatively thick wall 120 inserted so far that the front surface of the flange 114 preferably with the front wall surface of the Wall 120 is aligned. The housing is held by a nut 122 on the rear End of the housing 112, which in turn from one on the rear of the wall 120 in suitably attached plate 123 is held, e.g. B. likes the plate 123 Have approaches with openings through which screwed into the wall 120 Pass screws 125 through.

Alternatively, the nut 122 can be provided with lugs, the openings have passed through the fastening screws 125 or the like and so that the nut can be attached to the wall 120.

According to yet another alternative, see FIG. 18, the housing 212 is one provided at its rear end arranged flange 223, which in turn with Provide openings and screwed onto the wall 120 by means of screws 125 can be.

The housing shape used according to FIG. 7 is in detail in FIGS. 10A to 10D highlighted more clearly. This corresponds essentially to the embodiment 4C.

The form of an alternative latch construction shown in FIGS. 11A through 11D differs from the construction shown in FIGS. 3A to 3C in particular in that a threaded bore 119 near the end of the rotary latch 118 is provided, the threaded axis of which is parallel to the axis 175 of the rotary bolt, in which threaded bore 119 can be screwed in a cap screw 177, such that that the head of this cap screw works with a bearing surface 190 (FIG. 9A), such as 17 shows. The distance can be adjusted by turning this screw 177 Adjust 181 of the contact surface 190 to the flange contact surface 183, for example to take into account so different thicknesses of walls, or even desired Contact pressure. Lock nut 179 is used to fix this position 17, or 279 on the opposite side according to Fig. 18.

If the screw 177 is unscrewed completely, a contact surface 390 results.

Worth mentioning is an O-ring seal 183, which water or the housing 112, 212 makes it gastight.

In contrast to the depression 88 according to FIGS. 3A to 3C, there is a depression here 188 arranged on the opposite side of the tongue of the latch 118, and in the area of the drive shaft, but this serves the same purpose, namely the facilitated pushing a union nut 122 or the easier Insert the closure through a thin wall.

In Fig. 19, a still another rotary bolt lock 310 is in a side view recognize, consisting of a closure housing 312 with in already described Form a flange 314 at one end and one from its other End of the rotating latch 318, see the perspective view in 21A, the housing 312 in the manner already described by a to the External cross section of this housing adapted opening in a door leaf 320 preferably rotatably pluggable and here by means of the housing wall protruding integrally molded with the housing and made of plastic Holding springs 322 is set in this position. Complementary to the rotary latch 318 is on the cabinet housing or frame 321, preferably in the so-called Bending area between door leaf 320 and frame 321, a bolt receiving part 92 provided that the instead of a folded area of the cabinet housing Grip surface 322 for the rotary latch 318 forms. 19 and 21A leave, the bolt receiving part 92 has the shape of a bracket, the two ends have recessed openings for receiving fastening screws 94, with which the bolt receiving part 92 are attached to the cabinet housing 321 can, as shown in Fig. 21A. From the figure it is also clear that the Bolt receiving part has a cup shape, the cup base having a rectangular opening 96 with constricted corners, which is dimensioned so that a gag-like Rotary latch 318 in a position aligned with the longitudinal extent of the opening 36 can pass through with lateral play, as can be seen in FIG. 20A. Through the The width already mentioned is less than the length of this opening 96 Behind grip surfaces 323, behind the support surfaces 94 formed by the toggle 318 reach to the longitudinal direction when this gag from its shown in Fig. 20A the opening 96 aligned position brought into a position rotated by 90 ° as shown in Fig. 20B. This position is also shown in Fig. 21C.

By further actuation or further rotation through 90 ° is already described in the Way the toggle-type rotary latch is pulled into the housing 312, causing it from its position shown in Fig. 21C to the position shown in Fig. 21D arrives. During this movement process, the door leaf 320 is opened in the direction of pulled the door frame 321, and at the same time, that's the benefit of this Embodiment compared to the previously described embodiments, the Door leaf 320 aligned with the door frame 321, this alignment results in particular in the direction of the transverse extent of the opening 96 according to FIG. 21D, i.e. in the direction of the folds through the door leaf and door frame, because of this Directional travel only a protrusion of the gag foot 98 with little or no Play on the longitudinal edges 100 of the opening 96 when the gag is in its position shown in Fig. 20B. In the order shown in Fig. 20A In contrast, 90 ° rotated position remains play.

This alignment takes place in the direction of the fold of the door leaf or Door frame and is particularly important because in this direction z. B. as a result of Warping occurs. This is especially true for doors that are wider than are high and therefore warp particularly easily (small distance between the Hinges to each other, long lever arm of the door hinge point to the hinges).

The sequence of FIGS. 21A, 21B, 21C and 21D thus shows the closing process, starting in FIG. 21A with the pivoting of the door panel 320 onto the door frame 321 until the toggle-type rotary latch 318 still in the open position in FIG. 21B has penetrated the opening 96 of the bolt receiving part 92, whereupon with a Key, not shown here, first in the other two embodiments in a manner described in detail, the rotary latch 318 is rotated by 90 °, whereby it from the position shown in FIG. 21B to the position shown in FIG. 21C, during which process the door leaf 320 in the manner already described with respect to the door frame 321 in the direction parallel to the fold is aligned. By turning it another 90 °, the rotating latch is then released 318 pulled into its rotary bolt housing 312, whereby the door leaf 320 in Direction is pulled onto the door frame 321, causing the distance between these two parts reduced by about half as shown.

This spacing lock can serve to seal means, not shown to press against each other and thereby to seal the door.

The advantage of the arrangement according to FIGS. 21A, 21B, 21C and 21D is that the dead space between the folds and door frames can be used anyway. Because usually the seal at 102 between door leaf 320 and door frame 321 takes place, it also shows that here the closure is conveniently outside the sealed area of a cabinet is arranged so that no special Measures to seal itself must be taken. This also applies to the self-tapping screw 94 shown here because a self-cut thread is relatively tight. Alternatively, you can also use Fastening instead of the self-tapping screw 94 appropriate bolts with nuts and with sealing washers are used that enable sealing.

The embodiment shown in the figures is particularly favorable because it is particularly easy to install: the one to be fastened in the door leaf 320 The rotary latch component 312 only has to be clipped into the corresponding opening from the outside be while the component associated with the door frame 321 with two z. B. yourself even their thread-cutting screws can also be attached from the outside.
