State of the art

A not yet optimal pull-turn-latch closure is already known from the catalog pages 62, 63 and 67 of the catalog "Southco Compression Latches" from Southco. In the known closure according to the catalog page 62, the attachment takes place by means of a union nut from the front, according to catalog page 63, however, with a mother from behind and catalog page 67 by means of two rivets or two screws on the sheet.
A disadvantage of this prior art, on the one hand, that the assembly is very cumbersome. In addition, by vibration, the nuts or screws can be solved, which fall into the circuit and significantly reduce the reliability or reliability contained therein circuits. In addition, over the entire axial path of the tongue in the housing, the tongue in the open and in the closed position can be brought, ie, it is also a malfunction possible.
Since in the above prior art to pull out the drawer or the drawer or to open the door or flap even handles are to be attached, which are screwed in accordance with the prior art, this risk of loosening screws increases even further.

Furthermore, be on the US 3,146,010 A (DELLITH). This document discloses (the references in parenthesis refer to this document) a pull-turn-latch closure for mounting in a breakthrough in a thin wall, with an externally threaded shaft rotatably but axially non-displaceably mounted in the closure housing ), on which a bolt (36) provided with a suitable threaded bore is guided in such a way that, as indicated at the beginning, it performs an axial translational movement during rotation. Further, D4 discloses an axially slotted sleeve (48) having a flange (42) at one end, which has a mark (46) and is rotatably supported on the head portion of the housing, which sleeve engages a spring Flange of the sleeve with a spring-facing edge region, the spring and the outer end of the shaft is supported against the spring force, and the slot of the sleeve is penetrated by the bolt (see FIG. 2 ) and its rotary motion on the sleeve and thus transmits to the flange.

Object of the invention

The object of the invention is to provide a closure, on the one hand Avoiding incorrect operations and guarantees a higher level of operational reliability, in which no fasteners can be lost, and on the other hand allows a much simpler installation, for example by simply clipping in spring-loaded holding elements.

solutions

The above-mentioned object of Fehluerungsvermeidung is essentially solved in that the shaft is provided with an external thread on which external thread of the threaded hole provided with a bolt is guided, that an axially slotted, provided with a flange at one end sleeve engages around the spring which flange has a mark such as a cut or aperture and is otherwise rotatably supported on the head portion of the housing, and in that the flange of the sleeve with a spring facing edge portion supports the spring and the outer end of the shaft against the spring force the slot of the sleeve is penetrated by the bolt and transmits its rotational movement on the sleeve and thus on the flange, that the mark is aligned on the flange of the sleeve to the slot, that the housing also carries a mark, which in conjunction with the mark on Flange of the sleeve certain rotational positions of the Riege ls, in particular its e.g. 90 degrees offset end positions (latch in open and closed position) indicates, and that the mark on the flange of the sleeve is a cut or breakthrough, and that the mark on the housing is a color point so mounted that in one position (eg open position) of the bolt the incision or breakthrough the view eg releases a red color point, in the second position (e.g., the 90 degree closed position) e.g. the view of a green color point.

These features allow the user to take into account the position of the bolt in the operation, which helps to avoid incorrect operation. The avoidance of incorrect operation, on the other hand, also increases operational safety.

The operability is facilitated by the fact that according to the invention, the mark aligned with the flange of the sleeve to this slot (and thus to the bolt), because then, for example, can be controlled at several simultaneously operated closures, whether all bars are in the desired position (open or closed).

This is particularly true because the housing according to the invention also carries a marking which, in conjunction with the marking on the flange of the sleeve, determines certain rotational positions of the bolt, in particular its e.g. 90 degrees offset end positions (bolt in open and closed position), indicating.

Moreover, according to the invention, since the mark on the flange of the sleeve is a cut or breakthrough, and the mark on the housing is a color dot applied in such a way that in one position (e.g., open position) of the lock the cut or breakthrough looks at e.g. releases a red color point, in the second position (e.g., the 90 degree closed position) e.g. looking at a green color point, the control is particularly easy.

The operability is further facilitated if the flange of the sleeve according to a further development forms a projection / recess, which cooperates to the Drehwegbegrenzung with a return / projection on the housing.

The head part can form a handle (claim 4). This eliminates the need to provide a handle or finger grip to z. B. take off a drawer.

According to yet another embodiment (claim 5) may be stored in the head part of a drive for rotating the shaft, preferably in the form of a knob and / or a receptacle for a socket or for a plug-in tool, such as Phillips screwdrivers.

The free end of the body part may form at least one projection (claim 6), the / as a stop / stops for the rotational movement of the rotary bolt represents / represent (claim 6).

It may be favorable (claim 7), if the one stop for the rotary movement of the rotary bolt from the fuselage part, the other of a suitably arranged edge of a breakthrough in a bend or approach of the thin wall is formed, wherein the breakthrough is preferably rectangular or L- is shaped.

As already mentioned, the thin wall is preferably formed by a drawer, door or flap in a control cabinet.

Detailed description of the invention

The in the Fig. 1 to 16B illustrated train turn-bolt closures are not embodiments of the invention, but examples of the holding means to be used with the subject invention.

In Fig. 1 is an exploded view of a train turn-lock closure 10 for mounting in an opening 12 in a thin wall 14, in particular for the tension of drawers or drawers in cabinets 16, is shown. The pull-turn-latch closure 10 comprises a in a non-round opening, for example here in a rectangular opening 12 in a thin wall, as here the front surface of a drawer or drawer 14 fixable housing 18, a rotatable in the housing 18, but axially non-displaceably mounted, provided with external thread 22 shaft 20 to which a threaded hole 24 provided with a bolt 26 in the housing 18 upon rotation of the shaft by means of tools or hand, see the fluted operation knob 28, which still has a cross recess 30 for on its front surface Receiving a corresponding Phillips tool has. The bolt 24 is guided during rotation of the shaft such that it performs in the lying at the outer end of the shaft 20 stop position at least 90 degrees comprehensive rotational movement with the shaft in the lying away from the stop position position under guidance in a formed in the housing axial slot for the bolt during rotational movement of the shaft performs an axial translational movement along the axis of the shaft 20, wherein the bolt 26 is under compressive load of a shaft 20 embracing compression spring 32. This pressure force generates a friction between the external thread 22 of the shaft 20 on the one hand and the internal thread of the opening 24 of the bolt 26 on the other hand, so that a rotational movement of the shaft by means of, for example, the manual operation 28 leads to a pivoting of the bolt 26, as long as the bolt in its rotational movement is limited and a shaft rotation occurs. The limitation may be due to parts the housing, such as by the projections of the wall 34, which allow the latch 26 a path of movement (rotation) of approximately 90 degrees, see reference numeral 38 in Fig. 5E , There are also formed by the housing 18 two stop surfaces 34 and 38 can be seen, to create the side surfaces 40, 42 of the bolt 26 in the end position respectively. Once the latch has reached one of the two stop surfaces, further rotation of the shaft 20 by means of a knob 28 or the like. To an axial displacement of the bolt 26 on the shaft 20, thus slipping so z. B. from the outermost position on the shaft 20 away from this position and in the direction of the wall plane in the thin wall 14 in which the closure is mounted. When, for example, clockwise rotation of the knob 28 moves according to Fig. 2 the latch or the tongue 26 along the abutment surface 38, wherein the latch 26 in one of the wall 44, a fold of the drawer front panel 14, see Fig. 2 , formed rectangular breakthrough 48 can be swung. Subsequently, the bolt 26 moves along the axis 74 of the bore 24 of the bolt 26, wherein finally the latch 26 impinges on the lower end of the local slot 50 and upon further actuation of the closure the slot 14 according to Fig. 2 pulls upwards and deeper into the cabinet while pushing the drawer or drawer 14 inside the housing 16 inward and puts under tension. In this case, the last piece of translational movement of the bolt 26 is guided not only by the side wall 38, but in addition by a prismatic shape of the housing, which is adapted to the outer contour of the bolt 26 and ensures that upon reaching this area a rotational movement no longer but only one movement according to the rotational tolerance of perhaps 1 to 2 percent. This case is in the Figs. 5B, 5F and 5G shown.

The mounted within a thin wall position of the closure, for example, in the Fig. 3, 4 and 5 to recognize.

The housing 10 further comprises, in a breakthrough mounted position, a head portion or flange 12 covering the outer edge of the aperture 12, from which a body portion 54 projecting through the aperture 12 extends, of which Fuselage part in the direction of its outer surfaces resilient retaining elements 56 project, which form a contact surface or contact line or point 56 for play-free support of the body portion 54 on the edge or the edge 58 of the opening 12.

When housing 118 according to Fig. 13 is provided in the associated body part 154 at the narrow ends of the rectangular housing each have a retaining slot 60, in which a leaf spring 62, see the different views of Figs. 15A to 15C , can be inserted with its hook portion 64 such that the other end, the folded portion 66, extends into a formed behind the flange 152 recess 68 and there interacts with the edge of the associated aperture, while the housing holds in the breakthrough like a clip.

According to Fig. 1 holding elements are provided, which are limited by spring force of a coil spring 70 limited in the body portion 54 slidably mounted pushers 72 can be formed. In the housing 54 is, as in Fig. 1 recognizable, provided a the thrust member 72 receiving slot, which also has a recess for the coil spring 70, which is received by the rest of a suitable breakthrough in the thrust element 72. The thrust element 72 also forms a holding surface 58 which has such an angle with respect to the direction of movement that results in a self-locking of the thrust element 72 at its bearing slot, when after insertion of the housing 18 in the rectangular opening of a thin wall, the thrust element springs back and thereby the upper side of the pusher presses against the narrow side of the pusher passage in the housing 18.

If the housing is not yet mounted, the spiral spring ensures that the retaining element 72 can not move out of the housing by providing a nose in the housing which holds the spring, and thus also the thrust element 72.

In order to obtain a narrow construction, it is provided that the body part in the has substantially rectangular cross-section and extending from two opposite sides of the rectangle in each case at least one holding element, such. B. Fig. 1 lets recognize. There are two or four times (see Fig. 7 ) provided with respect to the shaft axis 274 symmetrically arranged holding elements 270. If opposing holding elements 272, 273 are used, they form a group and on both sides of the length is in each case a group arranged, see Fig. 7 ,

The headboard forms according to Fig. 7 a finger or handle 76, so that a special handle for pulling out of the drawer or drawer is no longer required. Inside the handle is according to Fig. 7 Also, the drive for rotating the shaft 220 is provided, preferably in the form of a knob 228 with corrugation and / or with a receptacle 230 for a socket or plug-in tool, such as Phillips 9. Again, the body part forms at its free end at least one projection that / which serves as a stop / stops for the rotary movement of the rotary latch.

Between the corrugated head 228 and the externally threaded shaft 220 is a bearing member 278, which may be integrally molded with plastic from the two aforementioned parts and which is rotatably receivable in a bearing bore 280. Between bearing circumference 278 and head 228 is an annular shoulder 282, which in the assembled state, see Fig. 8 , abuts a shoulder surface 284 of the housing 218 so that the pressure of the spring 232, which acts on a latch 226 and tries to pull it outward, can be absorbed. The latch 226 is as already described on the externally threaded shaft 220 by means of internal thread by rotating the shaft 220 axially displaceable. The outer position is determined by a retaining washer 286, which can be plugged onto the reduced diameter end 288 of the shaft 220, see also Fig. 9 ,

The housing 218 forms a further inner contact surface or round shoulder 90, see Fig. 5C , which serves as a contact surface for another disc 292, at which the Spring 232 can be supported with its one end, while the other end can be supported on the annular surface surrounding the threaded bore of the bolt 226.

In Fig. 16B is an axial sectional view and in Fig. 16A to recognize a side view of a shape in which the holding elements represent lever 356, which are limited to a thin wall 314 spaced parallel to the axis 398 pivotally mounted against the force of a spring 356.

In Fig. 17 is an exploded view of an inventive turn-turn-latch closure 410 for mounting in a breakthrough 12 in a thin wall 414, in particular for clamping drawers or drawers in cabinets 416, is shown. The pull-and-turn latch 410 comprises a housing 418, lockable in the housing 418, in a non-circular aperture such as here in a rectangular aperture 12 in a thin wall, such as the front face of a drawer or drawer 414 but axially non-displaceably mounted, provided with external thread 422 shaft 420, to which a matching threaded hole 424 provided latch 426 in the housing 418 upon rotation of the shaft by means of tools or hand, see the screw head 428, on its front surface nor a Phillips 430 to Receiving a corresponding Phillips tool has. The latch 424 is guided upon rotation of the shaft such that it performs in the lying at the outer end of the shaft 420 stop position at least 90 degrees comprehensive rotational movement with the shaft in the lying away from the stop position position under guidance in a formed in the housing axial slot for the bolt during rotational movement of the shaft performs an axial translational movement along the axis of the shaft 420, wherein the bolt 426 is under pressure load of a shaft 420 embracing compression spring 432. This compressive force generates friction between the external thread 422 of the shaft 420 on the one hand and the internal thread of the opening 424 of the bolt 426 on the other hand, so that a rotational movement of the shaft by means of, for example, the operation 428 leads to a pivoting of the bolt 426, as long as the bolt is not limited in its rotational movement and a shaft rotation occurs. The limitation may be through parts of the housing, such as through the Projections of the wall 434, which allow the latch 426 a movement path (rotational path) of approximately 90 degrees, see Fig. 21B , There are also formed by the housing 418 two stop surfaces 434 and 438 can be seen, to which side surfaces 442, 444 of the bolt 426 create each in the end position. Once the latch has reached one of the two stop surfaces, further rotation of the shaft 420 by means of a screw head 28 or the like. To an axial displacement of the bolt 426 on the shaft 420, thus slips so z. B. from the outermost position on the shaft 420 away from this position and in the direction of the wall plane of the thin wall 414 in which the shutter is mounted. When, for example, clockwise rotation of the head 428 moves according to Fig. 19B the latch or tongue 426 along the stop surface 438, with the latch 426 in one of the wall 45, a fold of the drawer front panel 414, see Fig. 19B , formed rectangular breakthrough 48 can be swung. Subsequently, the bolt 426 moves along the axis 74 of the bore 424 of the bolt 426, wherein finally the latch 426 impinges on the lower end of the local slot 50 and upon further actuation of the closure of the insert 414 according to Fig. 19B pulls upwards and deeper into the cabinet while pushing the drawer or drawer 414 inside the housing 416 inward and puts under tension. In this case, the last part of the translational movement of the bolt 426 is guided not only by the side wall 438, but additionally by a prismatic shape of the housing, which is adapted to the outer contour of the bolt 426 and ensures that upon reaching this area a rotational movement is no longer but only one movement according to the rotational tolerance of perhaps 1 to 2 percent. This case is in the Figs. 21A to 21C shown.

The mounted within a thin wall position of the closure, for example, in the Fig. 18B and 19B to recognize.

Housing 410 further comprises, in a breakthrough mounted position, a head portion or flange 11 covering the outer edge of aperture 412, from which a body portion 454 extending through aperture 412 extends, resilient members 456, 472, extending from the body portion toward its outer surfaces. 473 project, which form a contact surface or contact line or contact point 458 for play-free support of the body part 454 on the edge or the edge of the opening 12.

In the embodiment according to Fig. 17 holding elements are provided, which are limited by spring force of a coil spring 470 limited in the body portion 454 slidably mounted pushers 472 can be formed. In the housing 454 is, as in Fig. 17 As can be seen, a slot receiving the thrust element 472 is provided, which also has a recess for the spiral spring 470, which is otherwise received by a suitable opening in the thrust element 472. The thrust element 472 forms the rest of a holding surface 57 which has such an angle with respect to the direction of movement that results in a self-locking of the thrust element 472 at its bearing slot, when after insertion of the housing 418 in the rectangular opening of a thin wall, the thrust element springs back and thereby presses the upper side of the pusher against the narrow side of the pusher channel in the housing 418.

If the housing is not yet mounted, the coil spring ensures that the support member 472 can not move out of the housing by a nose is provided in the housing, which holds the spring, and thus the pusher 472.

In order to obtain a narrow construction, it is provided that the body part has a substantially rectangular cross-section and extending from two opposite sides of the rectangle in each case at least one holding element, such. B. Fig. 17 recognize. In this case, the double (or quadruple) provided holding elements 472 are arranged symmetrically with respect to the shaft axis 74. If opposing holding elements 472, 773 are used, they form a group and on both sides of the length one group is arranged, not shown.

The head part can form a finger or handle, not shown, so that a special handle for pulling out of the drawer or drawer is no longer required.

Between the head 428 and the externally threaded shaft 420 is a bearing member 78 which may be molded integrally with the above two parts of plastic, and which is rotatably receivable in a bearing bore 80 of a sleeve 101, so that the pressure of the spring 432 that acts on the latch 426 and tries to pull it outward can be caught. The latch 426 is as already described on the externally threaded shaft 420 by means of internal thread by rotating the shaft 420 axially displaceable. The outer position is determined by a retaining washer 86, which can be snapped onto the reduced diameter end 88 of the shaft 420 and riveted by swaging the end 88, see also Fig. 18B ,

The sleeve 101, which is supported with its flange 103 on the edge 105 of the housing 418, thereby forming a further inner abutment surface or shoulder 107, on which the spring 432 can be supported with its one end, while the other end to the Threaded hole of the bolt 426 can support surrounding ring surface.

The sleeve 101 is provided with an axial slot 102 and at its end with a flange 103 and surrounds the spring 432, which flange 103 has a mark 104, such as a cut or breakthrough and rotatable on the edge 105 of the head portion of the housing 418 is held. The flange 103 of the sleeve 101 supports the spring 432 and the outer end 28 of the shaft 20 against the spring force 432 with an edge region 107 facing the spring 432. The slot 102 of the sleeve 101 is penetrated by the bolt 426, so that its rotational movement is transmitted to the sleeve 101 and thus on the flange 103 with this rotational movement indicative mark 104.

When the marker 104 on the flange 103 of the sleeve 101 is aligned with its slot 102, as in FIG Fig. 17 shown, the operation knows directly in which Direction of the bolt points, see Figs. 18A and 18B with the bolt in the open position and Figs. 19A and 19B in closed position

The housing 418 may also carry a mark which, in conjunction with the marking 104 on the flange 103 of the sleeve 101, will provide certain rotational positions of the bolt, in particular its e.g. 90 degrees offset end positions (bolt in open and closed position), could indicate.

If the marking on the flange 103 of the sleeve 101 is a recess 104 or breakthrough, and the marking on the housing 418 is a color point attached in such a way that in the one position (eg open position) of the bolt 426 (FIG. Figs. 18A, 18B ) the incision 104 or breakthrough releases the view of, for example, a red color spot 113 mounted on the housing 18, in the second position (eg the closed position offset by 90 degrees, Figs. 19A, 19B ) For example, the view of a green color point 111, the lock state is indicated by the green color, the unlocked state, however, by the red warning color.

The flange 103 of the sleeve 101 may form a projection / recess that could cooperate with the rotational travel limit with a recess / projection on the housing 18, not shown.

If one wants to dispense with the clip fastening, the housing could also be screwed (for example with a union nut) to the thin wall or even glued by means of adhesive, not shown.

Figs. 22A, 22B, 22C and 22D show the closure according to the invention from all four sides and can be seen in particular the riveted to the shaft end 88 Washer 86.

Figs. 23A, 23B, 23C are perspective views of the closure, Fig. 23A partially cut open.

Bolt 420, spring 432, tongue 426, disc 86 and sleeve 101 form a spring-loaded unit, the sleeve 101 is taken with external indicator 104 of the tongue 426 on the 90-degree path, thereby indicating the locking position.

Instead of the illustrated head shape of the shaft 420, e.g. also a knurled knob or a small gag find use.

Claims (8)

1. A pull and turn bolt lock for mounting in an opening (12, 112) in a thin wall (14, 114, 214, 314, 414), in particular for bracing push-in units (14, 114, 214, 414), doors or flaps in control boxes (16, 216, 416), comprising a housing (18, 118, 218, 318, 418) which can be fixed in a non-round opening (12, 112) in a thin wall (14, 114, 214, 414), a shaft (20, 220, 420) which is borne rotatably in the housing (18, 118, 218, 418) but in an axially non-displaceable manner and which is provided with an external thread (22, 222, 422), on which shaft (20, 220, 420) a bolt (26, 226, 426), which is provided with a suitable thread, is guided under a pressure load by a spring (32, 232, 432), which encompasses the shaft (20, 220, 420), in the housing (18, 118, 218, 418) such that when the shaft (20, 220, 420) is rotated by means of a hand or a tool in the stop position on the outer end of the shaft (20, 220, 420) or when pressure is relieved, it realises a rotational movement comprising at least 90 degrees with the shaft (20, 220, 420), and, in the position remote from the stop position, when being axially guided, such as via an axial slot formed in the housing (20, 220, 420) for the bolt when the shaft (20, 220, 420) is rotated, a translational movement is realised in the axial direction, wherein the housing (18, 118, 218, 418) has a head piece which, in a mounted state, overlaps the outer rim of the opening (12, 112), such as flange (52, 152, 252, 352, 452), from which a body part (54, 154, 254, 354, 454), which projects through the opening (12, 112), extends integrally, wherein a sleeve (101), which is axially slotted (102) and provided with a flange (103) on one end, encompasses the spring (432), said flange (103) having a marking (104), such as a notch or opening, and, moreover, being rotatably held on the head piece of the housing (418), and wherein the flange (103) of the sleeve (101) supports, with a peripheral region facing the spring (432), the spring (432) and the outer end of the shaft (420) against the spring force, wherein the slot (102) of the sleeve (101) is gripped by the bolt (426) and transfers its rotational movement onto the sleeve (101) and thus onto its flange (103), such that the marking (104) on the flange (103) of the sleeve (101) is aligned with its slot (102), characterised in that the housing (418) also bears a marking (111, 113) which, in conjunction with the marking (104) on the flange (103) of the sleeve (101), indicates specific rotational positions of the bolt (426), in particular its end positions offset by 90 degrees (bolt in the open and in the closed position), for example, and in that the marking (104) on the flange (103) of the sleeve (101) is a notch or an opening, and in that the marking (111, 113) on the housing (418) is a colour dot applied such that in one position (e.g. open position) of the bolt (426) the notch or opening (104) enables the viewing, e.g. of a red colour dot, in the second position (e.g. the closed position offset by 90 degrees) e.g. the view of a green colour dot, characterised in that there protrude, from the body part (54, 154, 254, 354, 454) in the direction of its outer surface, resilient holding elements (56, 156, 256, 356, 450) which represent displaceably borne push elements (72) and a self-locking contact surface or contact line or contact point (58, 458) for supporting the body part (54, 154, 254, 354, 454) in a play-free manner on the rim or the edge (46, 146) of the opening (12, 212), and in that the body part (54, 154, 254, 454) has a substantially rectangular cross section and at least one holding element originates respectively from two opposing rectangular sides, and in that the holding elements (56, 156, 256, 456) are push elements (72) arranged symmetrically in relation to the axis (74, 274) of the shaft (20, 220, 420).
2. The pull and turn bolt lock according to Claim 1, characterised in that the flange (103) of the sleeve (101) forms a protrusion/recess, which works together with a recess/protrusion on the housing (418) to restrict the rotational path.
3. The pull and turn bolt lock according to any one of Claims 1 to 2, characterised in that the shaft (20, 420), which is provided with an external thread (22), has a head on its outer end in the form of a screw head (28, 428) with a crossed slot (30, 430) or a similar tool receptacle, or in the form of a knurled stud or in the form of a small lever.
4. The lock according to any one of Claims 1 to 3, characterised in that the head piece (52, 152, 252) forms a hand grip or finger grip (76).
5. The lock according to any one of Claims 1 to 4, characterised in that a drive (28, 228, 428, 30, 230, 430) for rotating the shaft (20, 220) is borne in the head piece (54, 254, 454), preferably in the form of a rotating knob (28, 228, 428) and/or a receptacle (30, 230, 430) for a socket wrench or insertion tool, such as crosshead screwdrivers.
6. The lock according to any one of Claims 1 to 5, characterised in that the free end of the body part (54, 154, 254, 454) forms at least one protrusion (34, 134, 434, 38, 138, 238, 438), which serves/serve as a stop/stops for the rotational movement of the turn bolt (26, 226, 426).
7. The lock according to any one of Claims 1 to 6, characterised in that one stop for the rotational movement of the turn bolt (26, 226, 426) is formed by the body part (54, 154, 254, 454), and the other stop is formed by a fittingly arranged edge of an opening (48, 248, 50, 250) in a bend or a shoulder of the thin wall (45), wherein the opening is preferably rectangular or L-shaped.
8. A use of a lock, according to any one of Claims 1 to 7, for a thin wall (14) of a push-in unit or for a drawer, door or flap in a control box.
