Description

The invention relates to a return spring device for door or window fittings according to the preamble of claim 1 and a door or window fitting according to claim 31.

Door locks usually have a spring loaded latch which is operable via door handles. The latter are usually rotatably mounted as components of a fitting on both sides of a door leaf in a stop body and connected via a square pin axially and rotationally fixed to each other. The square pin penetrates positively a lock nut, which is held within the door lock of a lock spring in an initial position. After pressing the door handle, the case is withdrawn and returned to its original position after releasing the handle. The same applies to the lock nut and the associated handle. If at least one of these handles is designed according to a button shape, then the force of the lock spring is usually sufficient to bring about the return of the door handle to its initial position. Angled handles or levers, which are often made of specific heavy material such as brass or steel, however, are often not fully raised due to their own weight in the rest position or the starting position and held in this position, especially if the lock spring after prolonged use already fatigued or too weakly dimensioned.

It has therefore equipped fittings with additional return springs, which should bring the handle in its initial position. DE 20 2004 012 051 U1 describes, for example, such a pusher arrangement. This has at least one attachable to a door and equipped with a bearing opening, for example, designed as a rosette, mounting element. A pusher which can be fixed axially thereon with a separate locking element has a guide neck section, which is rotatably received in a bearing bush against the action of a return spring. The latter accommodates both the square pin and the return spring. For the determination of the bearing bush, a lid is provided, which is latched by means of lugs with the mounting element. The problem here is that such a return spring arrangement is not universally applicable, but can be used either only for right versions or only for left-hand versions of a fitting, moreover, the operating angle of the handle is limited. Another disadvantage is the complex construction, which increases both the manufacturing costs and the assembly costs.

DE 100 52 495 A1 discloses a fastening device for a window and / or door handle, consisting of a flush-mounted bearing base with at least one opening and a bearing bush for receiving an axially fixed and rotatably mounted handle neck. The bearing bush is rotatably connected to the bearing base. It also has a locking device which has a spring-loaded locking means in the form of a locking ring for the storage and determination of the handle neck. The latter is manually movable against a compression spring in the direction of the bearing base, wherein the compression spring is also designed as a torsion spring to bring the door handle back to its horizontal position after releasing. For this purpose, a non-rotatably mounted on the handle neck drive plate is provided, which must be performed during assembly of the fitting with an angled driver pin between the unwound spring ends of the compression and torsion spring. This is not only very expensive, it also requires a certain amount of skill to bring the drive pin in the assembly of the handle neck exactly between the spring ends can. In addition, this structure is extremely complex and therefore expensive to manufacture. A pre-assembly of the return spring means is not possible. The operating angle of the handle is limited.

The aim of the invention is to avoid these and other disadvantages of the prior art and to provide a return spring means, which is constructed inexpensively by simple means and as simple as reliable to handle. The device should also be universally applicable and deliverable as a preassembled unit, although larger operating angles should be feasible. Another object of the invention is to provide a door fitting which is simple in construction and inexpensive to manufacture. The aim is also a rational installation and easy handling.

Main features of the invention are set forth in the characterizing part of claim 1 and claim 31. Embodiments are the subject of claims 2 to 30 and 32 to 42.

In a Rückholfedereinrichtung for door or window fittings, with a rotatably mounted in a housing against a restoring force driver element having a central axis to a rotational axis a square recess for receiving a square pin rotatably connected to at least one rotatably or pivotally mounted handle of the fitting, wherein the restoring force is generated by a spring element, the invention provides that the housing has a housing shell, which is provided for receiving the driver element and the spring element with a central recess, that the housing shell radially adjacent to the recess has two recesses between which a stop element for the spring element is formed, and that the driver element has a Mitnehmersteg for the spring element, the latter having two spring ends which are formed such that they lie on both sides of the Mitnehmerstegs and on both sides of the Ansc hlagelements engage in each case one of the recesses in the housing shell.

Pressing the handle of the fitting, the driving element of the return spring device is rotated in the housing over the square pin. In this case, the driver pin deflects on the driver element of one of the spring ends, which can move within the respective associated recess in the circumferential direction, while the other end of the spring element is supported on the stationary stop element in the housing. If you let go of the handle, this returns due to the force acting on the driver spring or restoring force back to its original position. The recesses can be dimensioned almost arbitrarily due to the simple geometry, so that with the device according to the invention in comparison to conventional constructions even larger operating angle can be realized easily.

Due to the substantially symmetrical position of the recesses on both sides of the stop element and the rotatable in both directions driver element in the housing you can perform the handle movement in the other direction, so that the return spring means can be easily used for both right and left hand grips; it is universally usable. The return spring device is thereby formed by the housing, the driver element and the spring element - thus only a few components. It therefore has a very simple and clear structure with simple geometry that is rational and therefore inexpensive to produce. All components can also be quickly and easily assembled into a unit, which ensures easy installation.

The central recess in the housing shell is substantially circular, so that it forms a bearing for both the driver element and, if necessary, for the handle of the fitting.

The recesses adjacent to the recess are preferably arcuate and coaxial with the recess, so that the spring ends engaging therein can move freely over the entire operating angle. This is limited in the circumferential direction only by the stop surfaces for the driver element and / or for the spring ends of the spring element, i. By appropriate choice of the arc length of the recesses can be realized in a simple manner different operating angle. constructive changes or even additional components are not required.

The preferably integrally formed with the housing shell stop element forms - as well as the arcuate recesses - a bow or ring section. It is limited in the circumferential direction of the stop surfaces of the recesses, so that the protruding into the recesses ends of the spring element can be supported in both directions of actuation of the stop element.

An advantageous development of the invention provides that the central recess of the housing is provided on the edge side with a step, wherein this forms a support surface for the driver element. The latter is provided for this purpose with two radially projecting tabs which rest slidably on the step of the recess of the housing. The driver element is thus always smoothly and reliably stored without complex bearing elements are necessary.

Also, the Mitnehmersteg the driver element forms a bow or ring portion, wherein the center angle of the stop element in the housing and the center angle of the Mitnehmerstegs on the driver element are preferably the same size.

The entrainment element is in its home or rest position, the Mitnehmersteg is preferably immediately adjacent to the stop element of the housing shell. Both together form a symmetrical circular sector with substantially straight side surfaces. At these, the spring ends of the spring element can always support reliable. The latter can be operated via the handle, the square pin and the driving element at any time in both directions by the Mitnehmersteg each entrains a spring end, while the other end of the spring remains on the stationary stop element. The spring element is stretched and leads - after releasing the handle - the driver element and with this the handle back to its original position. The handle of the fitting is thus always reliably brought back into its mostly horizontal starting position, regardless of the state of a possibly existing lock spring.

For storage and guidance of the spring element, the driver element has a neck portion, wherein the driver web and the neck portion are radially spaced, so that the spring element can be arranged therebetween.

The housing has a substantially cylindrical outer surface. This can - depending on the installation situation - be flattened laterally, at least in sections, in order, for example, to be laterally flattened. to be able to accommodate the return spring unit in a narrow door plate.

A further embodiment of the invention provides that the outer surface of the housing carries or forms radially protruding latching projections in order to be able to define, for example, a separate shield or rosette cover. This is e.g. then expedient if the housing is or forms a stop element for the fitting. It can then be fixed to a stop surface for fitting, with screw holes being formed in the housing for this purpose. To prevent rotation one can provide the housing in the area of the screw holes with cams, which engage in corresponding blind holes in the stop surface, usually a door leaf.

The invention further provides that the central recess of the housing forms a bearing opening for the handle of the fitting. It may be advantageous if the bearing opening is limited by a neck portion. The handle, in particular the handle neck, thus finds an always safe and wobble-free guidance.

In a further design of the return spring means, the housing has a cover. This is preferably positive and / or positive fit with the Housing shell connectable, in particular clamped and / or latched. Through the cover both the driver element and the spring element are secured in the housing, unless the driver element is fixed axially in the housing shell. In this case, the cover would be unnecessary.

The cover has a central recess which rotatably receives the driver. The latter can be provided for this purpose with an additional edge or a projection which engages rotatably in the recess. The driver element is thereby additionally or alternatively rotatably mounted in the housing. In order to ensure a low overall height, close the cover and the driver element flush with each other.

The spring element is preferably a torsion spring or a spiral spring, which lays with one or more turns around the neck portion of the driver element. The spring ends of the spring element extend radially to the axis of rotation of the driver element, so that they can always reliably abut the stop element of the housing and the driver pin of the driver element.

In order to provide a compact and easy-to-install return spring device, it is advantageous if the spring element has a depth in the axial direction, which is preferably smaller than the axial depth of the central recess in the housing shell. The depth of the spring element is determined essentially by the thickness of the spring element material used and the number of windings or windings. Measured in the axial direction, however, the depth of the spring element is always smaller than that provided for receiving the spring element depth of the recess, so that both the spring element and the driver element do not protrude beyond the end face of the housing shell.

The depth of the Mitnehmerstegs of the driver element in the axial direction is dimensioned so that it corresponds approximately to the depth of the spring element. That is to say the carrier web has a depth with which it always reliably detects both ends of the spring element.

Preferably, the spring is mounted biased, ie the spring ends cross each other and are characterized by bias on the stop element and the driving pin on. To adapt to different handle weights you can bring the spring element but also without bias. Constructive changes are not necessary.

To further reduce the assembly costs, the housing, the driver element and the spring element form a preassembled unit. These can be due to their simple geometry not only cost-effective manufacture, but also easily add automated. The housing, the driver element and the spring element are also all symmetrical, so that the return spring unit is not only used on both sides, but can also be installed in any position. Mounting and operating errors are thereby reliably avoided.

A door fitting for which independent protection is claimed is provided with a return spring device according to the invention, wherein at least one handle is rotatably or pivotably mounted on or in a stop element. The return spring device receives in its driving element on the square pin of the fitting, so that upon actuation of the handle, the driver element is rotated. The spring element in the housing of the return spring device is tensioned. If you let go of the handle, the driver element and the coupled handle - regardless of the state of a lock spring - always reliably moved by the spring element back to the starting position.

In order to ensure a permanently reliable storage of the handle, a guide ring is provided between this and the stop element. This serves as a plain bearing. He is preferably rotatably connected to the stop element.

A further development provides that the guide ring with the housing of the return spring means is non-positively and / or positively connected. The latter is thus fastened to the stop element and at the same time held against rotation, which is particularly advantageous if the stop element is a door plate. It is expedient if the housing of the return spring device can be inserted into the door plate. The return spring means is completely covered by the shield and is not visible to the outside, which has a favorable effect on the appearance of the fitting.

Another embodiment provides that the guide ring is integral with the housing of the return spring means. This is advantageous in particular when the stop element is a rosette and when the stop element is formed by the housing of the return spring device. This results in a particularly compact design. To cover the housing of the return spring means is on the Stop element a cover can be fixed, which is preferably latched to the radially issued locking projections on the housing.

The in Fig. 1 generally designated 70 fitting is designed as a door fitting. He has a handle 72 which is rotatably mounted with a handle neck 71 in a stop member 74. The latter, for example, has the form of a narrow door plate which is fixed by means of screws (not shown) to a door leaf (also not shown). To accommodate the screws 74 holes 73 are provided in the door plate.

Between the handle 72 and the door plate 74 sits a guide ring 75 with a bearing opening 25 for the handle neck 71. The ring 75 is inserted in a circular recess 76 in the door plate 74 and fixed by means of circumferentially arranged locking springs 85 therein. He also carries circumferentially radially flared projections 77 which engage in anti-rotation in corresponding recesses 79 in the edge of the recess 76. In the handle neck 71 of the handle 72 frontally a square pin 80 is rotatably inserted, which is axially secured by a grub screw 82. The square pin 80 engages through a back in the door plate 74 used Rückholfedereinrichtung 10 in a (not shown) Schloßnuß a lock in the door leaf.

The return spring means 10 is provided to bring the handle 72 always reliable after its operation in its horizontal starting position. It is designed as a preassembled unit and is composed of a housing 20, a driver element 40 and a spring element 50.

The housing 20 has a housing shell 21 and a rear-mounted cover member 27 in the form of a lid, which has substantially the same outer contour as the housing shell 21 and is provided with pins 39. The latter engage non-positively and / or frictionally engaged in corresponding holes or recesses 59 in the housing shell 21, so that a fast-to-install and permanently secure connection is ensured.

In the housing shell 21, a central circular recess 22 is formed for rotatably receiving the driver element 40 and the spring element 50. Radially adjacent to the recess 22, two arcuate recesses 30, 34 are introduced in the housing shell 21, which are bounded in the circumferential direction U respectively by end surfaces 31, 32 and 35, 36. In the middle between the recesses 30, 34, a stop element 26 is formed for the spring element 50, which also forms a bow or ring section. It can be seen that the recesses 30, 34 coaxial with the recess 22 and symmetrical to the stop element 26, wherein the end surface 31 of the recess 30 and the end surface 35 of the recess 34 at the same time form the boundary surfaces of the stop element 26 (see also Fig. 5 ). The arc length of the recesses 30, 34 is selected so that the angular distance between the end surfaces 31, 32 and 35, 36, for example, 60 °, which is readily possible due to the simple geometry of the housing shell 21.

On the side facing the door plate 74, the recess 22 in the housing 20 forms an opening 58 which corresponds in diameter to the recess 79 in the door plate 74. If the return spring device 10 is inserted back into the door plate 74, the guide ring 75 engages positively and / or positively with its detent springs 85 into the opening 58 and thus into the housing 20, so that the return spring device 10 is firmly connected to the door plate 74 , Recesses 57 introduced on the edge side in the opening 58 receive the radially protruded projections 77 of the guide ring 75, so that the housing 20 is also secured against rotation in the door plate 74.

The housing 20 has a substantially cylindrical outer surface 28. However, this is in the embodiment of Fig. 1 and 2 Flattened laterally, so that the return spring means 10 - as shown - can also be used in narrower door plates 74 and is always completely covered by these. The lateral flattening of the housing 20 also serves as rotation in the door plate 74. In order to fix the return spring 10 additionally or alternatively on the door leaf, at least two Schraubbohrungen 23 are introduced in the housing 20 at the edge, both the housing shell 21 and the cover 27th push through.

This in Fig. 6 Carrier element 40 shown in detail is rotatably supported in the recess 20 in the housing 20 against the restoring force of the spring element 50. It has a substantially circular disc basic shape and centric to the rotation axis A a square recess 42, which serves for the rotationally fixed coupling with the square spindle 80. Laterally projecting in the radial direction, the drive plate 40 has two diametrically opposite tabs 43, which are supported in a sliding manner in the axial direction on the housing shell 21. Its recess 22 is provided on the edge side with a substantially annular step 24, on which the tabs 43 slidably rest. The latter are in the axial direction offset from an edge step 45. With this, the driver element 40 is rotatably seated in a central recess 37 in the cover 27. This thus forms a pivot bearing for the driver element 40, via the between the annular step 24 and the cover 27 slidably guided tabs 43 is axially secured. In order to ensure a low overall height, close the cover member 27 and the driver element 40 flush with each other.

As Fig. 2 This web 44 forms - as well as the stop element 26 and the adjacent recesses 30, 34 in the housing 20 - a bow or ring portion whose center angle β the center angle α of the Stop element 26 corresponds (see Fig. 5 and 6 ). The stop element 26 and the entraining web 44 thus form mutually adjacent an annular circular sector, wherein the Mitnehmersteg 44, the side surfaces 31, 35 of the stop member 26 and the recesses 30, 34 continues radially to the axis of rotation A.

Coaxially to the axis of rotation A, the driver element 40 has a neck portion 46, wherein the driving web 44 and the neck portion 46 for receiving the spring element 50 are radially spaced.

The spring element 50 is preferably a torsion spring or a spiral spring that lies around the neck section 46 of the driver element 40 with one or more windings. It also has two radially to the axis of rotation A angled spring ends 52, 53 which lie on both sides of the Mitnehmerstegs 44 and engage on both sides of the stop element 26 in each case a recess 30, 34 of the housing shell 21. The spring ends 52, 53 thus close the annular sector formed by the stop element 26 and the Mitnehmersteg 44, wherein the side surfaces 31, 35 of the stop element 26 and the recesses 30, 34 serve as abutment surfaces for the spring ends 52, 53.

By turning the handle 72 in the housing 20, the cam member 40 rotates in one direction, e.g. to the right, the end 52 of the spring 50 is deflected by the Mitnehmersteg 44 in the circumferential direction U to the right, while the other end 53 is supported on the stop surface 31 in the recess 30 and the stop element 26. The spring 50 is tensioned. If you let go of the handle 72, the spring 50 rotates the driver element 40 via the Mitnehmersteg 44 back to its original position in front of the stop element 26. The handle 72 is moved back over the square pin 80 in its horizontal position.

During the rotational movement of the handle 72, the spring end 52 moves in the arcuate recess 34 until it abuts against the second boundary surface 36. This therefore forms a stop both for the rotational movement of the driver element 40 and for the pivoting movement of the handle 72. Due to the relatively large arc length of the recess 34 and the angular distance of 60 ° between the abutment surfaces 35 and 36, the handle 72 - conventional fittings with return spring means - perform a relatively large pivoting movement.

Due to the symmetrical design of the return spring means 10, in particular the symmetrical design of the recesses 30, 34, one can rotate the driver element 40 via the handle 72 and the square pin 80 in the other direction to the left. In this case, the carrier web 44 moves the spring end 53 in the recess 30 to the left, while the spring end 52 is supported on the stop surface 35. The return spring device 10 can therefore be used universally both for a right as for a left-hand operation, without the need for another component or that it requires design changes.

If necessary, the pivoting angle of the driver element 40 within the housing 20 can also be adjusted to e.g. Limit 40 ° by the arc length of the recesses 30, 34 is chosen correspondingly smaller. Another alternative provides that not the spring ends 52, 53 on the boundary surfaces 32, 36 of the recesses 30, 34 come to rest, but for example, the tabs 43 of the driver 40. Also by the pivoting movement can be limited, so that for example the spring element 50th not overloaded.

Fig. 3 shows its another embodiment of a fitting 70 according to the invention with an alternative design of a Rückholfederelements invention 10. Its housing 20 forms here directly the stop element 74 in the form of a rosette which is fastened by means guided in holes 23 (not shown) screws on the door leaf. In order to ensure a permanently secure hold of the stop element 20, 74 on the door leaf, 23 cams 33 are formed in the region of the bores, which engage in corresponding holes (not shown) in the door leaf.

The handle 72 of the fitting 70 is rotatably mounted with its handle neck 71 in the stop element 74 and thus in the housing 20 of the return spring means 10. The central recess 22 of the housing 20 forms the bearing opening 25 for the handle neck 71, which is preferably bounded by a neck portion 38 (see Fig. 4 ). It can be seen that the neck portion 38 forms the guide ring 75, which is thus integral with the housing 20 of the return spring means 10. An anti-rotation is therefore not necessary here.

To cover the housing 20 to the outside visually, a cover 78 is provided, which is placed on the housing shell 21. To fix the cover 78, the substantially cylindrical outer surface 28 of the housing 20 bears radially protruding latching projections 29 which can be latched to the inner circumference of the cover 78 (not described in more detail). One recognizes in Fig. 5 in that the housing shell 21 is provided with curved oblong holes 49 in the region of the latching projections 29, so that the latching projections 29 are seated on spring webs 89 and can radially spring inwardly when the cover 78 is placed on the housing 20. The cover 78 has a central opening 88 which receives the neck portion 38 of the housing shell 21.

All of the claims, description and drawings resulting features and advantages, including structural details, spatial arrangements and process steps, can be essential to the invention both for themselves and in the most diverse combinations.
