EP1711672B1 - Hinge for mounting in an opening - Google Patents

Abstract

A hinge has at least one hinge part which can be mounted in an opening in a thin wall such as a sheet-metal cabinet door, a head part, such as a flange or hinge leaf, which overlaps the rim of the opening of the thin wall on its (outer) side, and a body part which proceeds from the head part and can be pushed through the opening in the thin wall, and a holding part which is carried by the body part, supported on the other (rear) side of the thin wall, and is separate from the body part. The holding part is formed by holding elements which project in a flexible manner from the body part in the direction of its outer surface and whose free end has an inclined surface for supporting the body part on the rim or edge of the opening without play.

Description

Background of the invention

The invention relates to a hinge which has at least one hinged part which can be mounted in an aperture in a thin wall, such as a metal door, with a head part covering the edge of the thin wall breakthrough on one (outer) side thereof, such as a flange or hinge leaf, and one of the head part outgoing, through the opening in the thin wall slidable body part, and with a supported by the body part, on the other (rear) side of the thin wall supporting, separate from the body part holding part.

Brief description of the prior art

Such a hinge is already out of the EP 0223871 A1 known. In the prior art, the holding part consists of a pin 20 which is passed through corresponding holes of a hinge part and holds this hinge part in the corner of a control panel made of sheet metal. This type of assembly has the advantage that it allows for relatively thin sheets a stable attachment of the door leaf to a door frame, which is often not the case with pure screw hinges.

Disadvantage, however, is that the hinge is only suitable for very specific sheet thicknesses, deviating sheet thicknesses lead to a game or to a possible mounting. The pen can also be lost as a loose part

In addition, the installation is still somewhat cumbersome, in particular both sides of the door panel must be accessible.

Object of the invention

The object of the invention is to further improve the known arrangement, in particular with regard to the simplification of the assembly and a possible automatic adaptation to different sheet thicknesses of the thin wall. In addition, if possible loose parts should be avoided.

Certain existing in the prior art advantages should be retained if possible, so the inaccessibility of the hinge attachment with the cabinet closed, on the other hand, the solubility of the open cabinet, at least using a tool.

solutions

The object is achieved according to the invention in that the holding part is formed by retaining elements which project resiliently from the body part in the direction of its outer surface and whose free end has an inclined surface for play-free support of the body part on the edge or edge of the opening in the thin wall.

By this measure, a large part of the tasks which the invention has already met is already fulfilled. In particular, the assembly is greatly simplified, on the other hand, even very thin sheet can be kept safe. Different sheet thicknesses, if they do not exceed certain ranges, are kept free of play. Loose parts are usually not required.

Such a clip-like attachment is not yet known for the hinge in the form shown here. Known is a Klipsbefestigung for quick assembly of a closure housing, wherein on the U.S. Patent 5,435,159 is referenced. There, such a closure housing is arranged, for example in a round opening in a thin wall. The intended for a Vorreiberverschluß housing comprises a to be arranged on the one outer side of the thin wall, the outer edge of the breakthrough overlapping headboard, namely a flange, from which a breakthrough protruding in the mounted position fuselage, projecting from the direction of its outer surface resilient tongue elements at the free end an inclined surface for backlash-free support of the body on the frame of the breakthrough another, inner side of the thin wall. The disadvantage here is that the holding force of the integral with the body part holding or tongue elements is dependent on the spring tension, which depends on the plastic material used and therefore can not be made arbitrarily large. In hinge application but very large forces must often be absorbed, so that this type of Klipsbefestigung can not be easily transferred to a hinge part.

From the EP 0258491 is a similar construction known as from the U.S. Patent 5,435,159 with which a lock cylinder by means of the locking cylinder receiving, retaining tongues forming plastic housing in thin-walled doors, drawers od. Like. Can be fastened. By sloping surfaces at the ends of the tongue a desired adaptability to commonly occurring variations of the components to be locked is achieved. In column 9 of the document is also described that the resilient tongues after mounting the lock cylinder in the housing can not dodge to the inside. A disadvantage of this prior art that a very specific construction, namely a round housing with inserted therein lock cylinder, must be provided to allow this locking of the tongues after assembly. Again, the transfer of this tongue attachment to a hinge does not seem to be obvious.

When hinge according to the invention, in which the body part and the holding part are two separate parts, not injected as one piece of plastic as in the two last-mentioned pamphlets, results in a much greater load capacity, as required, a not so strong plastic material that splash easily can be combined with a stronger material, such as metal, so that the desired strength of the hinge is achieved by appropriate choice of material.

According to one embodiment of the invention, two diametrically opposed holding elements are provided, act on the pressure elements such as spring devices, in particular a two holding elements common coil spring or two coil springs or wedge devices, such as conical screws. Since the run-on slopes of the holding elements can be provided with different angles and the spring means can be provided with freely selectable spring force, the locking force can be adapted to the respective task and is not dependent on the plastic material.

In the prior art, the locking force is highly dependent on the material properties of the plastic used, unless you use a pen, but in turn makes the assembly in an undesirable manner complicated, especially since a blind assembly is not possible, which can be provided according to the invention.

According to yet another further development of the hinge, the retaining elements are at a distance from the rear surface of the thin wall, about a plane parallel to the plane of the thin wall axis limited rotatably arranged lever. This embodiment increases the holding force at the same spring strength.

Alternatively, the holding elements are at a distance to the rear surface of the thin wall about an axis perpendicular to this surface limited rotatably mounted lever. Thus, four breakpoints can be achieved with two levers simultaneously and thus also serves to increase the holding force with unchanged spring tension.

According to yet another embodiment of the invention, the holding elements in a parallel to the plane of the thin wall, rectangular in cross-section cylinder slidably mounted carriage, which are held by a latching between themselves or in the cylinder hook device against compression spring force. The advantage of this design lies in the relatively low height on the rear side of the door panel. A similar construction results when the holding elements of a parallel to the plane of the thin wall, rectangular in cross-section Cylinders slidably mounted slide of rigid material, such as metal, which are held by a pinning device arranged between them against compression spring force. This is a particularly sustainable hinge arrangement.

The cylinder may have a part partition or undercut or breakthrough edge on which the carriage can be axially supported with a shoulder or hook. This shows the variability of the construction according to the invention, which is advantageous.

A reduction of the construction is possible if, according to an embodiment of the invention, the holding element has an opening which receives a helical compression spring with at least a portion of its diameter.

In the breakthrough protrusions can protrude to hold the spring element radially.

In particular, the holding elements can be formed by two adjacent flat metal pieces, each having an opening, which two openings together form a space which accommodates a helical compression spring with at least a portion of its diameter. With the construction, a favorable pre-assembly can be made possible, in which these three parts are held together by the spring, that they can be handled separately from the remaining part of the hinge. This also applies if the holding elements are formed by two adjoining metal pieces which form mutually facing projections / recesses which limit the axial sliding movement relative to each other. Here is the added advantage of the Bewegungswegbegrenzung without further action on the cylinder.

According to one embodiment of this construction, the holding elements of two juxtaposed plastic or metal pieces are formed, which form mutually facing projections / recesses, with a rotatable tool or Key are engaged in such a way that upon rotation of the tool or key, the plastic or metal pieces are moved against each other against the spring force. This makes it possible to withdraw the two effective holding elements here without great finger effort, thereby releasing the hinge part from the opening of the thin wall as needed. Since this is possible only with a specific tool that is not available to everyone, this also represents a favorable safety aspect. As already mentioned, another advantage can be achieved in that the holding elements are formed by a piece of metal or two adjacent pieces of metal, the one or the other is jointly held by a spring / such that these three parts form a stable, manageable unit.

Instead of the pinning device or in a further development of the pinning device, a fixing pin or fixing plug or fixing screw can be provided for fixing the retaining elements after mounting the hinge part in the opening.

A construction in which the head part has a return in the region of the holding elements, proves to be advantageous in that it also bumps the edges of the breakthrough are harmless if they are not too large. If the edges are bulged only slightly, the contact surface is increased, so that larger forces can be absorbed.

The holding elements can also be formed by a suitably bent leaf spring. According to a development, the leaf spring can be inserted in a radially extending cavity formed by the body part. The cavity may form a slot or recess into which a projection / recess of the spring snaps into place in the working position. On the other hand, the leaf spring may be held by a cap screw screwed into a threaded bore formed by the body part. Alternatively, however, the leaf spring can be dotted on a surface formed by the body part (welded) or glued.

An alternative arises when the hinge part has an opening like the thin wall and the holding part and the body part have their own headboard. Incidentally, the head part and the body part can also be two parts which are screwed together, or else also glued to one another or otherwise non-detachably or detachably connected parts.

It may be advantageous to arrange several holding elements in the axial direction of the hinge next to each other. On the other hand, it is also possible, a second hinge part, which is pivotally connected to the first hinge part, to give an analogous structure, as the first hinge part has him. As occasion demands, it may be favorable if a second hinge part pivotally connected to the first hinge part has a different structure with respect to its attachment to a frame, such as a door frame, or to a door leaf, than the first hinge part. Thus, the second hinge part could be welded to the frame or door leaf. On the other hand, the second hinge part could be bolted to the frame or door leaf. Yet another alternative is to glue the second hinge part to the frame or door leaf. Finally, it is also possible to attach the second hinge part to the frame or door leaf by means of a clamping pin, as in the prior art.

Best ways of carrying out the invention

1A, 1B, 1C and 1D show, in various views, a hinge 10 constructed according to the invention, with at least one in an opening 12, which is rectangular here, see, for example, FIG. 2, in a thin wall 14, such as a metal door 14 mountable hinge member 16 and another hinge member 18 which is pivotally connected to the first hinge part by means of a hinge pin 20 and may be attached to a door frame 20, see Fig. 1A. The respective hinge part 16 or 18 mountable on the metal door 14 (as well as on the frame 22) comprises a head part 28 covering the edge 24 of the opening 12 in the thin wall 14 or 22 on its one (outer) side 26, such as flange or here leaf of a hinge, and extending from the head part 28, through the opening 12 in the thin wall 14 therethrough fuselage body portion 30, and supported by the body portion, on the other (rear) side 32 supporting, separate from the body portion 30 holding part 34, wherein the holding part 34 is formed by holding elements 36, which holding member 36 of the body portion 30 in the direction of its outer surface resiliently protrudes and whose free end an inclined surface 38 play-free support of the body portion 30 on the edge or the edge 40 of the opening 12 in the thin Wall 14 (or 22). Because of the symmetry of the forces, it is favorable that, for example according to FIG. 4B, two holding elements 36-1 and 36-2 arranged diametrically opposite each other are provided, acting on the spring devices 42, for example a common one to the two holding elements 36-1 and 36-2 Spiral spring 42 or a respective spiral spring 42-1, 42-2 act in the sense that the holding elements 36 are urged in the direction of the edge 40 of the opening 12. As shown in Fig. 4B, the holding elements 36-1, 36-2 at a distance A to the (rear) surface 32 of the thin wall 14 about an axis 46 parallel to the plane of the thin wall 14 disposed lever 44 may be. The angle of rotation of the lever 44 is limited by stop means 48, while in Fig. 4B, the holding elements 36 at a distance A to the (rear) surface of the thin wall limited to axis 46 are rotatably arranged.

As shown in Fig. 3A, the arrangement of the holding members 136-1, 136-2 such that they are arranged as sliders 52 arranged axially displaceably in a plane parallel to the plane of the thin wall 14 or 22 and rectangular in cross-section cylinders 52, which carriages 56 by a latching between themselves or in the cylinder 50 hook device 54 against compression spring force of the spring 42nd 3B, with the hooks 54, or in FIG.

According to FIGS. 5A, 5B and 5C, the holding elements 236 shown there are limitedly rotatable about a lever 586 which is rotatably arranged so as to be limited to the thin wall 214.

The cylinder 50 may also have a part partition or undercut or breakthrough edge 60 on which the carriage may be axially supported with a shoulder or hook. Thus, FIG. 8A shows a hinge member 316 having a body portion 330 in which carriages 352 can retract against the force of a spring 342 through the edges of the aperture upon insertion due to chamfer 62, see FIG. 8A, until the edge reaches the clamping surface 64 has, in which position the spring 342 presses the two fasteners 352 against the edges of the opening and the hinge part 316 with the thin wall 14 firmly connects. So that the holding elements 352 can not be lost in an opening before assembly, they hook each other by hooks 354, see FIG. 8C. Nevertheless, they are possible to avoid each other when inserting and to obtain the position shown in FIG. 8B. Fig. 8D shows that in the extended state, the central layer is secured by a fixing plug, also, the fixing plug 66 will prevent removal of the hinge, that the holding members 352 can not be pushed back into the cylindrical housing, see Fig. 8D. The holding element shown in Fig. 8F, 8G and 8H as a single part also shows the space 368 for the compression spring 342. A return path 70 receives the tip of the fixing plug 66 and allows the holding elements only a limited lifting movement. Another recess 72 allows a sliding side by side of the two mutually movable holding elements.

Fig. 7C shows in a sectional view a thin wall 14 made of sheet metal, in which areas of the breakthrough edges are bulged due to heavy load. In this case, it is favorable if the head part in the region of the holding elements has a recess 74, into which the bulged edge regions 24 can be received. This allows, by pushing the holding member 36 continues a backlash-free attachment.

FIG. 9A shows an end view and FIG. 9B shows a side view of a hinge part 434, which is composed of four adjacent pairs of holding elements. The construction is similar to that of FIGS. 4A, 4B, but a common axis 446 is provided for supporting the opposing support members 436. The axle pin 446 is held by three posts 74, with a post receiving a corrugated surface of the axle pin end in compression.

The holding elements 436 have at their end a projection 76 which leads in conjunction with a recess in the head part 428 to a Drehwegbegrenzung due to the spring force 242. The particular advantage here is also that the head part 428 and the body part, formed by the supports 74, also can be easily sprayed, although here a groove 78 is provided for a seal that would normally require sliding devices with injection tools.

The hinge shown in Fig. 1 comprises a second hinge part 18 which is pivotally connected to the first hinge part 16, and has a different construction as the first hinge part 16. On the other hand, Fig. 5A shows a second hinge part 218 which is pivotally connected to the first hinge part 214, but with respect to its attachment to a frame, such as door frame 222 or on a door leaf has a different structure than the first hinge part, here welded to it is. The second hinge part can also be screwed to the frame or on the door leaf, see Fig. 2A. Alternatively, however, the second hinge part can also be glued to the frame or on the door leaf. Finally, an attachment of the second hinge part on the frame or door leaf by means of a clamping pin, as in the prior art, possible.

10, a door 14 is pivotally connected to a frame part 22 via a hinge 10, wherein the two hinge parts are held by means of holding elements 36 respectively in the frame 27 and door leaf 14.

For symmetry reasons, it is favorable to provide the other side of the cabinet with corresponding openings, these openings serve there for the attachment of a rod locking element. In the embodiment according to FIGS. 11A, 11B, 11C, 11D, the holding elements 536 are formed by two adjoining metal pieces or plastic pieces. They form mutually facing projections / recesses, such that with a rotatable tool or key 82, the two holding elements 536-1, 536-2 retracted by rotating the tool 82 against the force of the spring 542 and thereby dismantling the hinge of the door panel 514 can be. The structure is suitably made so that the lever 82 automatically remains in the open position, so that all hinges can be brought into the open position simultaneously with multiple hinges and so all hinges are simultaneously deductible from the door leaf.

In the embodiment according to FIGS. 11E and 11F, the tool is provided with a pinion 84, which engage in corresponding toothings 86 of the two holding elements 636-1, 636-2 and also upon rotation of the tool with the pinion 84 retracting the two Holding elements is made possible in the housing, so as to pull the housing from the opening in the thin wall.

This opening is possible from the side of the hinge, so from outside the door leaf area, you can also solve his blind assembly again.

In contrast, in the embodiment according to FIGS. 12A, 12B, 12C, a solution with tool is provided from the inside.

The 45 ° inclined surface 127 of the holding elements 736, see in particular FIGS. 12C and 12G, causes them to be urged by the spring pressure of the spring 742 outward in the direction of the channel walls 129, which creates friction in the channel and the holding elements may already be sufficiently fixed by this friction, so that the recognizable in Fig. 12A fixing stopper 131 is not needed. If the plug 131 for securing the holding elements 736 is not required, the plug 131 does not need to be removed if the release key 133 is to be inserted through the opening 135 in the manhole cover 137 into the return area 139 formed by the two holding elements 736. When the key 133 is then turned counterclockwise as shown in Fig. 12A, the key pushes its wings 141 against the end surface 143 of the recess portion 139, thereby displacing the retainer 736 into the channel until the position shown in Fig. 12I is reached Time the key is turned 90 ° and holds itself. Then, the entire unit shown in FIG. 12A can be withdrawn from the aperture shown in FIG. 12D in the thin wall 714, including possibly other hinge elements which have also been brought into the retracted position with a corresponding key.

In the embodiment according to FIGS. 12J, K, L, M, N, O, P, the holding element used is a flat piece of metal, which has an opening 84 for receiving the spring 42, and two opposing projections 86, which adjoin the spring 842 record this secure, so that here is a handle unit of holding element and spring is given.

This unit can be received in the correspondingly shaped opening 88 in the body part 38, see FIG. 12K, the recess 90 provided for the spring is shorter than the corresponding recess 92 for the holding element 836, whereby the spring 842 receives a contact surface, if the Retaining element 836 is pushed in the position shown in FIG. 12J.

If you bring a nub 94 at the end of the recess 90 for the spring, the spring can hold there and is prevented from falling out of the holding member 836 with the spring 842. Similarly configured is the embodiment according to FIGS. 18A, 18B, 18C, wherein the fastening element in FIG. 18D and the spring in FIG. 18E as firmly assembled parts are shown in Fig. 18F and 18G. Supporting projections are provided in FIG. 18H, wherein, in addition, for reasons of stability, the retaining element has a shape deviating from the flat shape, see FIG. 18I.

In the embodiment of FIGS. 19A, 19B, 19C, two springs are provided, each of which is inserted laterally into the associated holding element 36. The other half of the spring element is received by the body part 1030. Fig. 19A shows the special feature that in the case of very thin wall material reinforcing plates 94, 96 are provided on both sides, which are clamped by the holding elements and thus also hold the thin door leaf 1014 and support.

In the embodiment of FIGS. 19D, E, F, G and H, two adjacent pieces of metal 136 are provided, which are held together by a spring 1144 so that these three parts form a stable handle unit, ie handled separately and if necessary then can be inserted into a corresponding recess in the body part 1130, as can be seen in Fig. 19E.

By here nubs 1192 can also be achieved here that the construction holds in position.

As shown in Fig. 19H, the two metal parts are strengthened so that they can accommodate the spring as a whole.

An embodiment is shown in FIGS. 13A, 13B and 13C, in which the holding part 1234 is fastened to the head part 1228 by means of spot welding 94. In FIGS. 13E, 13D, a suitably designed leaf spring as a holding member is spot-welded to the body part 328, see the welding points 1398.

Figures 14A and 14B show a hinge in which the leaf spring 1436 is inserted into a radially extending cavity 100 formed by the body portion.

This cavity forms a slot 102 or a forward / backward jump, in which a projection or recess 104 of the spring 100 can lock this in position fixing.

In the hinge arrangement shown in FIGS. 15A, 15B, 15C and 15D, the leaf spring 1536 is held by a cap screw 108 screwed into a threaded bore 106 formed by the body portion 1530. For better guidance, a lid 111 may be provided which is U-shaped and engages with its leg ends in recesses 113 in the head part 1528, which recess 113 also form abutment surfaces 115 and 117 for the ends of the spring 1536.

16A, 16B, 16C and 16D, a hinge is shown in which the hinge part has an opening 119 like the thin wall 1614, wherein the holding part 1634 and the body part 1630 have their own head part 1628. The hinge part shown in Fig. 16D also has holes 145 for an alternative attachment by means of cap screws.

In the embodiment shown in FIGS. 17A, 17B and 17C, head portion 1738 and body portion 130 are two parts bolted together, with two screws 17108 being used. To increase the stability, the pairs of retaining elements 1736 are present in duplicate, and arranged symmetrically to the right and left of the screw 17108.

Also in the embodiment illustrated in FIGS. 20A-20L, the head portion 1828 and body portion 1830 are two different, bolted-together, 18107 components. The holding elements 1836 have a slot 121 through which the screw 18107 is guided and thereby limits the axial movement of the holding element 1836. The hinge forming head portion 1828 has a groove 123 for a circumferential ring seal 125.

In Fig. 21 is shown in a cross-sectional view, partially in section, a hinge part, which is not according to the invention, the holding elements 1936 are spread by a screw with conical foot 147. In the embodiment shown in Fig. 23, the head of Screw 149 conical and pushes the two holding elements 2136 apart.

Compared to a construction according to FIG. 22A, in which a spring spreads the two holding elements 2036, the conical screw embodiments have the disadvantage that when the sheet edges later buckle or buckle under load, the screw has to be tightened by hand. A spring automatically slides and compensates automatically.

The aperture in the thin wall need not necessarily be rectangular, as shown for example in FIG. He can also have any other shape, such as oval or round. A round embodiment can be seen in Fig. 22B, but must be provided for a rotation lock, which does not provide the round breakthrough shape in contrast to the rectangular breakthrough shape. Securing the first hinge part (eg, attached to the door) can be done, for example, by the second hinge part, if it is fixed firmly enough (eg on the frame), or by the arrangement of two, as can be seen in Fig. 22B spaced apart circular apertures 2012, or by additional molded on the hinge part pins 151 which prevent rotation, see Fig. 22C, if appropriate holes are present in the door leaf, which receive these pins.

On the other hand, Fig. 25A shows a conventional hinge for flush application. The two hinge parts are bolted to the door leaf 2314 and 2322 in the door frame. Since both hinge parts 2318, 2316 are screwed and the holes in the frame part 2318 are accessible only in the disassembled state of the hinge, the customer must install the hinge parts themselves on the cabinet and hitting the hinge pin 2320 or hold with retaining rings, which is very expensive for the customer. The solution according to FIG. 25B is better: the hinge part 2418 to be fastened to the frame 2422 can be clipped in as a pre-assembled hinge due to its equipment with a holding part 2234 according to the invention and then the hinge part 2416 to be connected to the door can be screwed to the door or also possibly clipping in.

Fig. 26 shows in a cross-sectional view a window frame 2514 with an elongated aperture 2512 in which a pressed aluminum profile hinge portion 2516, not in accordance with the invention, can be slid in to subsequently secure it with a T-shaped wedge element 2536. Since the press tool and production are simpler, the production is cheaper. Also, the eye for a pin 2520 can be left open and can be produced by pressing.
