Description

The invention relates to a securing device for securing a handle rotatably received with a pusher neck approach according to the preamble of claim 1. The invention further relates to a fitting with a securing device according to the preamble of claim 10th

Such safety devices and fittings, especially for doors and windows, are well known.

From the DE 10 2006 047 702 A1 For example, a door fitting is known. The door fitting comprises a base fitting, which in particular comprises a base rosette, and is suitable for mounting on a door leaf. Further, the door fitting comprises a Unterrosette for supporting a door handle which is rotatably engageable with the base fitting, arranged between the base fitting and the Unterrosette return mechanism for pushing the door handle and a cover rosette to protect the base fitting and to provide a decor function. Here, a trained for repeated opening detent spring for latching fixation of the door handle is rotatably received in the base fitting. Next, a recess is formed in the lower rosette for access from the front to the detent spring. In addition, the detent spring with a standard tool, especially with a screwdriver, to open from the front. The structure of this fitting is complex with relatively many items that require a high assembly cost.

Next is from the EP 0 406 566 B1 a rotary handle, in particular a window handle, known. The rotary handle comprises at the bottom a shoulder with a bead having handle neck and a subsequent to the latter above handle main body. Further, the rotary handle comprises a penetrated by screw holes stop plate, which has a central sleeve for guiding the rotatable and axially fixed to it attachable handle neck, which is provided with a square hole for the positive reception of a square actuator. The handle neck approach is resiliently latched by plugging into the socket on or in it both in the circumferential and in the axial direction. Also, this structure is relatively complex with many individual functional units that require a high assembly cost. In addition, such a rotary handle usually has no reset or hold-up mechanism for a handle.

It is an object of the present invention to provide a security device and a fitting, which allow a simpler structure. In particular, it is an object to accomplish a functional integration of a plurality of functional units, so that a modular-like fitting can be realized, which is mountable on site and allows fittings with low heights.

The above and other objects are achieved by a safety device according to claim 1 and a fitting according to claim 10. Advantageous developments of the invention are specified in the dependent claims.

The invention includes the technical teaching that in a securing device for securing a rotatably received with a handle neck approach pusher for fitting in an axial direction and in a circumferential direction, in particular for a rosette device of a door and / or window fitting, holding-up means in the securing device are integrally formed to hold the pusher in a raised position when installed and to reset the pusher after an actuation of the pusher in the hold-high position.

The securing device comprises means for axial and in a circumferential direction non-rotatable securing a pusher neck. The axial direction is the direction in which the pusher is inserted into the rosette device, that is, the direction of the axis about which the pusher is pivotable. The circumferential direction is corresponding to the direction of rotation, in which the pusher is pivoted. The pusher neck is axially and rotationally secured by simply plugging into the securing device, wherein at least a part of the means for securing yield during insertion elastically and then act accordingly with a restoring force against withdrawal of the pusher. The fuse can be positively, force and / or friction or cohesive, preferably at least one fuse is positively in one direction.

The high holding means are designed so that they are always anxious to bring the pusher in its hold-up position, that is in the installed state in its unactuated position, even against the weight of the pusher. For this purpose, the high holding means preferably comprise at least one spring unit, more precisely a spring-storage unit which applies a restoring force in order to position the pusher in a corresponding manner. The holding (or resetting) takes place counter to a rotational or actuation direction of the pusher, so that the pusher after its operation in the unactuated or hold-high position, z. B. in a horizontal position, remains or is reset. Upon actuation of the pusher, the high-holding means are clamped accordingly, so that after the actuation of the reset of the pusher takes place. In contrast to prior art devices according to the present invention, the high holding means are in the securing device (or vice versa) integrated, that is, the securing device and the high-holding means form a coupled, directly operatively connected unit. In this case, at least one component or a component is designed such that it is a component of both the securing device and the high-holding means.

In one embodiment, it is provided that the securing device has at least one axial securing device and at least one circumferential securing device, wherein the retaining means are integrated in the circumferential securing device. That is, the securing device, more precisely the circumferential securing and the high holding means, have at least one common component. Accordingly, the high-holding means and the circumferential securing are coupled to one another via the at least one common component.

In a further embodiment it is provided that the high-holding means comprise a prestressable spring unit and a holding-up device, wherein in the assembled state, the spring unit acts biased on the holding-up device. The operation of the pusher takes place in a rotational or circumferential direction. Accordingly, the holding means act in or counter to the circumferential direction to reset the pusher. That is, the spring unit is biased in the direction of rotation of the pusher. Accordingly, the spring unit acts in the prestressed state against the direction of rotation to reset the pusher. The spring unit can be any spring unit. Preferably, the spring unit comprises at least one compression spring, more precisely a spiral compression spring. The spiral compression spring acts radially to the circumferential or rotational direction. The force exerted by the spring force is deflected and / or transmitted via the hold-up device in order to produce an effect in the direction of rotation. This transfer or deflection preferably takes place via a slide element with bevelled surfaces. The surfaces are at an angle not equal to 0 °, 90 °, 180 °, 270 ° and / or 360 ° to the effective direction of the spring. Preferably, the surfaces and the effective direction of the spring form an angle of about 30 ° to 60 °, in particular about 45 °. Preferably, the spring unit comprises a plurality of springs, in particular four springs, which act on the slide element, preferably on two slide elements, each having at least one, preferably two inclined surfaces.

Therefore, an embodiment provides that the holding-up device comprises at least one movable slide element, which moves against the bias of the spring unit when the push-button is actuated. Preferably, two opposite, opposite acting slide elements are provided. The slide elements each have two inclined surfaces in relation to the effective direction of the spring units and are V-shaped to each other. For interaction with the spring units, the slide elements on receiving openings for the spring units, so that they are securable at least in one direction. For a corresponding bias of the spring units, the spring units are axially tensioned by the slider elements and an opposite component, for example, a housing, a tab or the like. The slider elements move toward each other or away from each other upon actuation of the pusher and the return in opposite directions.

The integrated design of safety device and holding means is realized, in particular via a disc. Therefore, it is provided in a preferred embodiment that the circumferential securing comprises a substantially form-fitting and / or backlash the trigger neck approach in an opening in the circumferential direction securing receiving disc, which cooperates with the slider element. The disk is externally formed on its periphery substantially complementary to the slider elements, that is, cooperating with the surfaces of the slider elements. Inside, the disc is circumferentially complementary to formed a pusher neck. The formation of the corresponding contours is not rotationally symmetrical in both cases. Due to the non-rotationally symmetrical formation, in particular in cooperation with the trigger neck, an essentially positive, preferably also play-free connection is realized. When the trigger is turned, the disc follows this (rotary) movement. In this case, the sliding elements in engagement with the disc are pressed against the force of the spring unit to the outside. About the slopes of the slider elements, the rotational force is deflected into a radial force and / or transferred, which biases the spring units. After the end of the operation, that is at a maximum rotation of about 45 ° and releasing the handle causes the tension of the spring units, more specifically the restoring force of the spring units that the slide elements move towards each other in the direction of the disc and the disc on the deflection by the sloping surfaces is moved back to their original position.

In order to realize this interaction, it is provided in one embodiment that the slide element at least partially surrounds the disc, in order to effect the transmission of force from the handle-operable disc to the slide element prestressed via the spring unit and vice versa.

This cooperation is preferably realized in that the disc has circumferentially at least one projection or a projection region, which is surrounded by a corresponding recess of the slider element contacting to effect a power transmission. The recess defines the inclined surfaces of the slider element. The projection (-sbereich) of the disc is formed corresponding to the recess of the slide element. The slider element and the disc are thus engaged with each other.

A further embodiment provides that the axial securing device has at least one movable retaining element and at least one prestressable spring unit acting on the retaining element, which in the operational state presses the retaining element radially to the axial direction. Upon insertion of a pusher, the holding element is moved radially away from the pusher against the force of the spring unit, so that a slight insertion of the pusher can be realized. When the pusher is pushed in, the restoring force of the spring unit acts on the retaining element, which in turn acts against the pusher and prevents it from being pulled out axially.

In one embodiment, it is provided that the holding element at one end opposite to the spring unit has a projection which is designed for an axial securing for engagement in the circumferential groove of the pusher neck approach. In this way, a positive engagement of the pusher is realized. About the snap can be realized in addition to the axial securing and an axial stop, so that the pusher can only be inserted by a predefined amount, namely exactly to the snap. After latching a rotation of the pusher is possible because the projection of the holding element engages in the circumferential or at least partially circumferential groove, which allows a rotational movement, more precisely a pivoting movement. Over the length of the at least partially circumferential groove can also realize a stop for the rotational movement of the pusher. There may be provided a plurality of holding elements and / or a plurality of projections which engage correspondingly in a plurality of partially circumferential grooves or a circumferential groove over the entire circumference.

The invention further includes the technical teaching that in a fitting, in particular a door and / or window fitting, a pusher with a circumferential groove having pusher neck approach and a rosette device for rotatably receiving the pusher on the Pusher neck approach are included, wherein the rosette device comprises the securing device according to the invention.

The fitting, in particular the door fitting, is fastened to a (door) wing in order to move it and make it lockable or lockable. For this purpose, the fitting, inter alia, a pusher and means for attaching the pusher to the door, for example, a rosette device, on.

In order to receive and secure the pusher, which is designed, for example, as a rotatable or pivotable lever, in the rosette device, the pusher has a pusher neck (neck) with the circumferentially extending groove or a plurality of grooves. Next, the pusher neck (neck) on flats or surfaces, so that a non-rotationally symmetrical (outer) contour of the handle neck neck is realized. The pusher neck is inserted into a complementary opening of the rosette device, wherein the securing device secures the pusher neck axially and rotationally fixed in the rosette device. For this purpose, an axial lock engages at least partially in the circumferential groove. Due to the complementary contours of the pusher neck and the corresponding opening an essentially positive rotationally fixed connection is realized.

The pusher can be easily plugged into the opening on site and is secured by the securing device according to the invention. In this case, the securing device causes a circumferentially rotationally fixed and axial securing of the pusher in / on the rosette device. By the integrated holding means the pusher is always kept in an operative position, the hold-up position, or brought into this after actuation.

In order to release the pusher from the rosette device, the rosette device has a corresponding access or breakthrough. The access is designed as an opening, which realizes a passage to at least one of the spring units. The access can be acted upon against the bias of the corresponding spring unit, so as to realize a release of the pusher.

In order not to adversely affect the overall visual impression of the fitting, the access can be covered by means of a covering rosette from the outside.

Due to the integrated design, it is possible to realize a fitting with a low overall height. In one embodiment, the height of the rosette device measured from the door leaf in a vertical (i.e., normal) direction thereto is less than 12 mm. In particular, the overall height is in the range of greater than or equal to 7 mm to less than or equal to 12 mm, more preferably greater than or equal to 8 mm to less than 11 mm, and preferably approximately 9 mm.

By means of the securing device according to the invention with the retaining means integrated in the securing means, this low structural height can be realized. For this purpose, it is preferred that the pusher neck approach at least partially has a non-rotationally symmetric region and the opening of the disc has a complementary, the corresponding portion of the pusher neck approach receiving area to effect a substantially positive circumferential securing the pusher. In this case, the complementary regions are formed so that a possible backlash-free recording of the trigger neck approach is ensured in the opening.

The retaining means integrated in the safety device preferably comprise two slide elements, which are arranged opposite one another are. These interact with the help of spring units such as compression springs with the disc having the opening.

The pusher has a in its rest position horizontally extending pusher body and a vertically extending from the rosette body pusher neck, which is angled at 90 ° to the pusher body is aligned.

The rosette body according to a first embodiment of the arrangement of the rosette device on an elongated shape with an extension direction which extends 90 ° to the horizontal. The direction of movement of the holding elements and the slide elements and the longitudinal direction of the spring unit are arranged in the extension direction of the rosette body.

According to a second embodiment, the arrangement of the rosette device is designed as a shield body of a fitting and in particular as a long plate or as a short plate with an elongated extension. It can be provided that the extension direction of the executed as a shield body of a fitting rosette body is rotated by 90 ° to the horizontal, wherein the direction of movement of the holding elements and the slider elements and the longitudinal direction of the spring unit in the horizontal. Consequently, this second embodiment of the holding means and the securing means corresponds to a 90 ° relative to the first embodiment rotated arrangement.

It is further provided that two apertures are provided in the shield body through which access to the spring units is made possible with a tool, said apertures are arranged in a horizontal arrangement adjacent to the passage opening for receiving the pusher in the shield body. This arrangement is necessary because the shield body has two passages for passing a respective mounting bushing wherein at least one passage is disposed vertically below the passage opening, and wherein the distance between the passage opening and the passage has a dimension of 15mm to 25mm, preferably 20mm to 23mm, and more preferably 21.5mm.

The rotated arrangement is necessary because in an arrangement of the two passages for carrying out a respective mounting bushing in the direction of movement of the holding elements and the slider elements and the longitudinal direction of the spring unit, a spatial distribution of the passages on the one hand and an arrangement of the securing device with the support means on the other hand would not be possible. As a result, the possibility is provided to maintain the Führungsmaß between the through hole for receiving the pusher and the passages for the mounting bushes of 21.5mm, and on the other hand to integrate in any embodiment of the shield body of a fitting as a long shield or short shield the securing device with the high holding means.

Further measures improving the invention are specified in the dependent claims or will become apparent from the following description of an embodiment of the invention, which is shown schematically in the figures. All features and / or advantages resulting from the claims, the description or the drawings, including design details, spatial arrangements and method steps, can be essential to the invention, both individually and in the most diverse combinations.

Fig. 1 shows a perspective view of a pusher 1 before insertion into a rosette device 2. The pusher 1 is designed as a door handle, more precisely as a tubular door handle and has a pusher body 3 and a pusher neck 4. The pusher body 3 and the pusher neck 4 are arranged at an angle to each other, which in the present case is about 90 °. Along the pusher neck 4 extends approximately centrally a rotary axis or pivot axis, not shown, about which the pusher 1 is rotatable or pivotable for actuation after insertion into the rosette device 2. At the end of the pusher neck 4 arranged opposite the pusher body 3, the pusher neck 4 has a pusher neck lug 5, which is designed to be received in the rosette device 2. The pusher neck 5 is formed substantially cylindrical or annular cylindrical, wherein two surfaces 6 (only one of which is visible) flattened formed thereon, so that a non-rotationally symmetrical (outer) contour of the pusher neck approach 5 is realized. In addition, the pusher neck lug 5 has a circumferential groove 7. With the pusher neck approach 5, the pusher 1 is received in the rosette device 2.

For this purpose, the rosette device 2 has a corresponding securing device 8, which in more detail in Fig. 2 is described.

Fig. 2 shows enlarged a section of Fig. 1 , In this section, the area of the pusher neck approach 5 and the rosette device 2 shown enlarged. The rosette device 2 has the securing device 8 for receiving the pusher neck attachment 5. The securing device 8 comprises an axial securing 9 and a circumferential securing 10.

The axial securing 9 secures the pusher 1 against axial release in the direction of the pivot axis. For this purpose, the axial securing device 9 has a plurality of projections 11 which can be latched into the circumferential groove 7 of the pusher neck attachment 5 and which are described in greater detail below.

The circumferential securing 10 secures the pusher 1 rotationally fixed in the rosette device 2, so that rotation of the pusher 1 relative to the receiving part of the circumferential securing 10 is prevented. For this purpose, the circumferential securing device 10 has a disk 12 described in more detail below with an opening 13. The opening 13 is complementary to the pusher neck 5, more precisely formed the outer contour of the pusher neck approach 5, that is, with a substantially circular opening cross-section which is formed flattened corresponding to the surfaces 6 of the pusher neck approach 5. Thus, the opening 13 also has a non-rotationally symmetrical cross-section, like the corresponding pusher neck lug 5. The presser neck lug 5 can thus be received in a rotationally fixed manner in the opening 13 in a form-fitting and play-free manner.

The detailed structure of the handle-rosette device arrangement is in Fig. 3 described.

Fig. 3 shows in perspective an exploded view of the rosette device 2 with the safety device 8 from above. The rosette device 2 comprises a rosette body 14, which acts as a housing for the rosette device 2. The rosette body 14 is formed substantially parallelepiped-shaped, wherein this approximately centrally a cylindrical passage opening 15 has. At the ends considered in the longitudinal direction, the rosette body 14 has correspondingly formed end regions 16, which are designed to receive further components. The two end portions 16 are formed in the illustrated embodiment mirror-symmetrical to each other. Each end portion 16 has a recess 17 which is substantially circular in shape, the axes of the recesses 17 are arranged parallel to the central axis of the through hole 15 and in the longitudinal direction in alignment therewith. The recesses 17 are each designed to receive a corresponding mounting bushing 18 for attachment to a door leaf, not shown. The mounting sockets 18 can be received so that they shoot approximately flush with a corresponding surface of the rosette body 14.

Next, the end portions 16 each have a slot 19 for a corresponding holding element 20, which is presently designed as a retaining clip. The holding element 20 can be inserted at least partially into the rosette body 14 through the slot 19, so that a projection or a plurality of projections 21 of the holding element 20 project into the passage opening 15. In this case, the holding element 20 is guided in each case in the slot 19.

Furthermore, the rosette body 14 at the end portions 16 in the longitudinal direction extending lateral holes 22 for receiving spring units 23, which are presently designed as helical compression springs, on. The bores 22 extend substantially parallel to the slot 19.

At the central passage opening 15, a guide lug 24 is formed, which can be covered by an attachable cover ring 25.

To the rosette body 14 is in the Fig. 3 from below a rosette base 26 attachable. This has, viewed at its two ends in the longitudinal direction, four angled lugs 27, which lie opposite the end regions 16 during assembly.

Also in the middle, the rosette lower part 26 has a central through-bore 28, which in the assembled state is formed concentrically with the through-opening 15. In this through hole 28, a corresponding guide bush 29 can be used.

The retaining elements 20 with the projections 21 together with a respective spring unit, not shown here form the axial securing 9. The circumferential securing 10 and the high holding means 33 are in Fig. 4 described.

Fig. 4 shows in perspective an exploded view of the rosette device 2 with the safety device 8 from below. For a better overview, not all parts of the Fig. 3 listed again. Fig. 4 shows the rosette base 26 and the rosette body 14. The rosette body 14 has in the direction of rosette base 26 a receptacle 30 for the circumferential securing 10. In addition, 14 receiving chambers 31 are formed for the spring unit 32 in the rosette body, which cooperate with the holding elements 20 of the axial securing 9. The spring units 32 are designed as leaf springs, which can be used in the wing profile-like receiving chambers 31. In Fig. 4 are also the spring units 23, which are formed as a spiral compression spring, inserted into the corresponding holes 22.

In the circumferential securing 10 high holding means 33 are integrated. The circumferential securing 10 and the high holding means 33 comprise the spring units 23, at least one, in the present case two, slide elements 34, and the disk 12 with the passage opening 13 the integrated holding means 33 is inserted into the receptacle 30 and thus sandwiched between the rosette body 14 and the rosette base 26. The receptacle 30 and the arrangement of disc 12 and the two slide elements 34 are matched to each other, in the present case in the assembled state approximately cuboid. The slide elements 34 have on their sides in the longitudinal direction, that is in front of the head, receiving openings 35 for the spring units 23 which project through the holes 22 project into these receiving openings 35. In order to produce a bias of the spring units 23, limit the tabs 27, the spring units 23 in the assembled state, so that the spring units 23 between slide member 34 and tab 27 are biased in the bore 22.

The slide elements 34 are formed in the plan view approximately V-shaped. The disk 12 is approximately square in plan view. In the assembled state, the disc 12 and the slide elements 34 are formed so that the disc 12 projects with one corner in the recess of the V-shaped recess of the slide elements 34. When assembled, this results in the plan view of an approximately rectangular shape of disc 12 and slide elements 34th

By the biased spring units 23, the sliding elements 34 are pressed together, thus keeping the disc 12 in position. The passage opening 13 of the disc 12 is formed corresponding to the handle neck neck 5, that is, the through hole 13 receives the handle neck neck 5 substantially positive fit and backlash. By the biasing force of the spring units 23, which is transmitted to the disc, the pusher 1 is held up by the disc 12 in its unactuated position or returned to its unactuated position.

Upon actuation of the pusher 1, which is secured against rotation in the disc 12, the disc 12 is rotated. Here, the two slide elements 34 are pushed apart against the force of the spring units 23. If the operation is canceled, the restoring force of the spring units 23, the pusher 1 via the power transmission by means of slide elements 34 and disc 12 back into its hold-up position.

Fig. 5 shows in perspective the pusher 1 and the rosette device 2 from a lateral perspective. The securing device 8 with the axial securing device 9 and the circumferential securing means 10 and the integrated holding-up means 33 is modularly assembled into a compact unit. This unit has a low overall height in the axial direction, which is in particular less than 12 mm, preferably less than or equal to 11 mm, more preferably less than or equal to 10 mm, and preferably approximately 9 mm. For protection and for a visually appealing appearance, a covering rosette 36 can be put over the compact structural unit. This surrounds the rest of the rosette device 2 and completes this. The cover rosette 36 has laterally two openings 37, in which locking elements 38 of the rosette device 2 can engage in order to realize a kind of clip closure. As a result, the cover rosette 36 is secured to the rosette device 2.

Fig. 6 shows in perspective a fitting 40 with a tool 41 during disassembly of the assembled fitting. For dismantling the cover rosette 36 is lifted from the rest rosette device 2. As a result, the rosette body 14 is accessible. The rosette body 14 has an opening 39 in the region of the spring units 32 designed as leaf springs, so that access to these spring units 32 can be realized. In this breakthrough 39 and 39 these breakthroughs can be intervened with the corresponding pliers-like tool 41 and the spring units 32 are pushed apart. As a result, the axial securing device 9 can be released and the pusher 1 axially pull out of the rosette device 2. Likewise, the tool 41 can be used for mounting the fitting.

• Im Gegensatz zu Beschlägen gemäß dem Stand der Technik, welche Bauhöhen von etwa 12 mm bis 15 mm aufweisen, ist es durch diese Erfindung möglich, alle Türdrückerformen bestehender Programme zu verwenden, ohne dass diese im Werk montiert werden müssen. Durch die vorliegende Erfindung weist der erfindungsgemäße Beschlag 40 eine festdrehbare Verbindung und eine Hochhaltevorspannung auf. Der erfindungsgemäße Beschlag 40 mit allen Funktionen weist nur noch eine Bauhöhe von Drücker 1 und Schlüsselrosette oder Rosetteneinrichtung 2 von etwa 9 mm auf. Durch eine Rastverbindung kann der Türdrücker 1 auf die Rosetteneinrichtung 2 montiert werden, indem der Türdrücker 1 in die Rosettenführung eingeführt wird und einrastet. Durch ein Federpaket 23 in der Rosettenunterkonstruktion 14,26 bzw. dem Rosettenkörper 14 wird der Drücker 1 in der Mittenstellung (Hochhalteposition) gehalten. Die Profiltürrosette bzw. die Rosetteneinrichtung 2 hat die Aufgabe, den Drücker 1 oder andere Gusstürdrücker fest drehbar zu lagern und diesen in einer waagerechten Position zu halten.

In summary, the following can be stated:

• In contrast to prior art fittings, which have construction heights of about 12 mm to 15 mm, this invention makes it possible to use all the door pusher molds of existing programs without having to factory-mount them. By the present invention, the fitting 40 according to the invention has a firmly rotatable connection and a holding-up bias. The fitting 40 according to the invention with all functions has only one height of pusher 1 and key rosette or rosette device 2 of about 9 mm. By a latching connection, the door handle 1 can be mounted on the rosette device 2 by the door handle 1 is inserted into the rosette guide and engages. By a spring assembly 23 in the rosette substructure 14,26 and the rosette body 14 of the pusher 1 is held in the middle position (high holding position). The profile door rosette or the rosette device 2 has the task, the pusher 1 or other Gusstürdrücker firmly rotatably store and keep this in a horizontal position.

The fixedly rotatable mounting is generated by the engagement of the groove groove or the groove 7 in the door handle guide or the presser neck lug 5 and the securing surfaces of the retaining clip or the retaining element 20.

The horizontal position of the pusher 1 is held by the fact that the surfaces 6 of the pusher guide 5 are pushed onto the driving surfaces of the holding plate 12.

The two retaining clips 20 are inserted into the slots 19 of the rosette base 14 until the locking surfaces 21 from the opening 15 in to emerge from the leadership. The retaining clip 20 is then secured by the leaf spring 32 is inserted into the spring chamber 31.

The guide bush 29 is pressed into the steel lower part 26.

The high-holding slide 34 and the retaining plate 12 are inserted into the rosette base 14. Then, the compression springs 23 are inserted into the holes 35 of the high-holding slide 34. The compression springs 23 are brought under bias and the steel base 26 is fitted so that the surfaces keep the compression springs 23 under bias. The surface of the slider engages under tension to the surface of the disc 12,
