EP1144780B1 - Rotor arrangement for an armature arrangement - Google Patents

Abstract

The invention relates to an armature arrangement (10) which can be mounted in bores of a door which horizontally meet, a window or the like and which has handles (20) which are non-rotatably linked to a rotor (40). A two-armed catch (50) acts upon a rotor bridge (45). Said catch can be swiveled in opposite direction to the movement of the rotor (40) to actuate a spring-biased latch (15). Said rotor is operated by a recuperator spring and is mounted in an axially stable manner in a housing (30). The driving connection between the rotor (40) and the catch (50) can be optionally established or disestablished by means of a coupling device (200). The coupling device is actuated by a handle (olive turning handle 207, 208) which can be engaged with the rotor (40). A short catch-arm (54) effects coupling or decoupling by means of a driving pin (201) which can be lifted and lowered in relation to the rotor bridge (45) by turning wings (216) of each coupling half (202). The two coupling halves (202) are connected via a rod (206) in a non-rotatable but axially releasable manner. Said rod can be displaced on a 90 DEG curve within the rotor (40) which guides the driving pin (201) in aligned slots (210) in a radially movable manner. A handle core (217) can be axially engaged with a recess (222) of a coupling half (202).

Description

The present invention relates to a rotor arrangement for a fitting system according to the preamble of claim 1.

In a modern fitting system according to EP 0 574 594, which intersect in two Drilling of a room closure component - a door, a window or the like. - Is mountable, it has proven to be particularly advantageous that a factory Preassembled fitting assembly in a short time, e.g. from less than 1 min the door or window element can be struck. By operating a handle, about a handle, button or the like, a spring-loaded trap is withdrawn, so that the door or window can be opened. The power flow starts from Handle over a rotatably connected rotor to one contained therein Bridge. A driver mounted eccentrically in the housing is a pivotable lever trained with two arms of different lengths; it is moved in the opposite direction to the rotor. The shorter arm is traditionally supported on a contact surface of the bridge, while the long arm engages with coupling extensions at the rear (inner) end of the trap stands. When the handle is released, all components move under the influence of compression springs back to their starting positions.

Such fitting systems can be completed by the rotor in its sleeve-shaped Storage is locked, for example with one arranged in the handle axis Slider that can be actuated translationally or by rotation. The handle closed in this way, however, cannot be pivoted. Because now the user behavior it can assume that even closed systems can be swiveled when trying to actuate it can easily come to a heavy load from the construction must be caught.

It has also been shown that there is a need for such fittings Locking system-compatible and possibly interchangeable locking cylinders on site to be able to assemble what was previously not possible with the systems mentioned.

It is an important object of the invention to overcome these and other disadvantages of the prior art Overcoming technology and a fitting system of the type mentioned with economic To improve means and constructively clear, stable design so that Convenient lockability ensured and the user habits account is worn. Components and groups with existing hardware systems should also be compatible or easily replaceable. Furthermore, one becomes special the tight fit of the assembled fitting system is aimed for.

Essential features of the invention are specified in claim 1. refinements are the subject of claims 2 to 12.

In a rotor arrangement for a fitting system that crosses in two horizontally Drilling a door, a window or the like. is mountable and at least has a handle rotatably connected to a rotor, with a drive connection to a two-armed driver, which is used to actuate a spring-loaded latch is pivotable in opposite directions to the movement of the return spring rotor, and with an axially fixed, essentially cylindrical housing in which a sleeve leading the trap can be screwed in transversely to the rotor axis Invention according to claim 1 before that the drive connection between the rotor and Carrier is selectively producible or can be canceled, the Driver has an arm that can be brought into or out of engagement with a driver pin is. If necessary, the positive form-fit between the rotor and the driver can be effective Power flow can optionally be interrupted mechanically. The constructive The effort for this arrangement is small; thanks to its small footprint, it can also be used fit well in the fitting assembly.

The design of claim 2, according to which the driver pin, proves to be advantageous radially movable and optionally drive-connectable with the two-arm driver is. The extremely space-saving arrangement requires particularly low design effort. It is also favorable if the driver pin according to Claim 3 can be raised and lowered with respect to the rotor axis, namely by inevitable simultaneous rotation of wings of each coupling part. Therefore corresponds to the Driver pin functionally of the conventional contact surface, but it can be in In contrast to their rigid shape or position, avoid.

Further expedient refinements are specified in claims 4 to 11. The eccentric arrangement of a rod that rigidly twists the two coupling parts, but axially detachable, allows good accommodation even in confined spaces. When locked, the driver pin can be rotated parallel to a lower locking position arrive while opening again by attacking the wing side surfaces comes into an upper release position. Every grip remains in the usual way Way swiveling.

The rotor arrangement of claim 12 is characterized in that the rotor housings inserted into the door or window with multiple bracing can be anchored, preferably by axially screwing on a screw rosette assigned, counter-rotating external thread and by radially screwing in the Trap sleeve in the housing. A triple bracing is achieved and thus an extraordinarily tight fit, which can also withstand heavy use over the long term has grown.

1 shows the components of a fitting unit 10. Their structure corresponds generally a fitting system described in WO 93/25788 A1. A trap 15 is loaded by a compression spring 16 and guided in a trap sleeve 18 which in a Longitudinal bore of a door (not shown) can be used. In one of these crossing cross hole, a rotor 40 can be installed, which handles with fitting 20 is connected. The main function is to operate the withdraw spring-loaded latch 15 on coupling extensions 19.

According to the invention, the flow of force from the handle 20 takes place via the handle with it rotatably rigidly connected rotor 40 to a pin 201 located therein, on which a can support short arm 54 of a driver 50, which is opposite to rotor 40 rotates and engages the coupling extensions 19 with a long arm 52. To Release the handle 20, all components move under the influence of Compression springs 16, 34 return to their starting positions. The springs 34 are on or in Rotor 40 housed. This is divided in its central plane of symmetry and thus axially insertable into a likewise mirror-symmetrical housing 30, which too has openings 35 on both sides for this purpose. Cheeks 48 of the rotor 40 are with Rotary stops 47 and bayonet attachments 49 are provided. On inner end faces 191 of Handles 20 have matching bayonet recesses 123.

The housing 30 is generally cylindrical in shape. It is with at both ends External threads 214 provided. Eccentric to the axis of the housing 30 and parallel to it a bearing pin 53 is available. A driver 50 can be pivoted on it attached, namely a sheet metal stamped part with a back 51, which down as long arm 52 continues and of which short arms in the form of cheeks 54 with holes are angled for the bearing pin 53.

With the axially screwed rotor 40 handles 20 are rotatably connected, the handle neck holes 209, in each of which a rotating arch 207 (FIG. 1 right above) or a locking cylinder 208 (Fig. 1 bottom left) can be used axially.

Such an element is each provided with an axially parallel tongue 230, which with a clutch 200 cooperates. Their structure is shown in FIG. 3. she has two coupling parts 202, each with a wing 216 and an outer square 221 exhibit. The latter has a step 219 with a protrusion 222 of a core 217 interacts, which in an axial bore 223 a centering pin 224 of the clutch 202 records. The two coupling parts 202 are non-rotatably connected by a rod 206, which is in particular a square pin. For the frictional connection to the driver 50 a driver pin 201 which is radially movable in elongated holes 210 is provided. At the 2a, 4a and 5a, the incomplete fitting system rests in cross section preferably circular cylindrical driver pin 201 on the circumference of the wing 216 of the coupling parts 202, which sunk mirror-symmetrically in the rotor end faces are arranged. It can be pivoted via the short arms 54 of the driver 50 (Fig. 4b) so that its long arm 52 over the coupling extensions 19 when actuated by the handle causes the retraction of the trap 15.

Fan-shaped depressions 205 form solid rotary stops on the side for the wing side surfaces 204 of the coupling parts 202 projecting axially on both sides from the rotor 40. These are rotatably connected to each other by the square pin 206, so that they both always rotate inevitably and congruently. On the outside Ends of the coupling parts 202 are the turning handles 207 and 208 through the handle neck holes 209 of the handles 20 can be coupled.

Starting from the switching state according to FIG. 2a, the clutch 200 rotates 2b, 4c and 5b the driver pin 201 its two radial support. As a result, it falls in the two aligned slots 210 of the rotor 40 parallel to its axis of rotation downwards. With handle actuation the pin 201 now engages in the void (Fig. 4d), whereby the driver 50 and the Trap 15 remain in their starting positions. The hardware system is in this Position locked, but in contrast to the prior art allows pivoting the handles 20.

If the coupling 200 is rotated in the opposite direction by 90 °, the wing side surfaces lift 204 the driver pin 201 back to its upper starting position, where it is on the circumference of the clutch wing 216 rests (Fig. 2a). The pin 201 stands again with the short arm 54 of the driver 50 in engagement, so that when the handle is actuated the trap 15 is withdrawn.

The handles (revolving 207 and lock cylinder 208) can be axially through the Push the handle neck holes 209 flush into the fitting unit 10, which can also happen on site. Through holes are on the handle tabs 230 211 provided that a fixing of the tongues 230 inside the Allow rotors 40, for which purpose countersunk screws 212 are provided (FIG. 1). Thereby are the handle core 217 via their projections 222 with the outer parts 221 of the Couplings 202 in operative connection.

In contrast to conventional comparable fitting systems, the unit 10 stable by multiple screw tension on a (not shown) door leaf struck. Two screw rosettes 213 (FIG. 1) serve this purpose, from both sides be screwed onto the counter-rotating external thread 214 of the housing 30, in the the sleeve 18 can be screwed in radially with a thread 37. All three screw connections introduce tensile stresses in different directions into the housing 30, thereby it is clamped securely and in the correct position on the door sash.

While the revolving arches 207 with an inner square longitudinal profile (see FIG. 2a) the outer square 221 of the coupling parts 202 are positively attachable Lock cylinder 208 a freewheel in the direction of rotation; on the non-operated door side they do not rotate when locked or unlocked on the opposite side of the door becomes. It can be seen from FIG. 3 that the frontal projection 222 of the core 217 does this is designed as a quarter circle sector. A central hole or an axial bore 223 in the core 217 receives the coupling-side centering pin 224. Both coupling parts 202 have a flat cross section 225 which is semicircular in shape axial engagement with the quarter circle sectors 222 of the cores 217 always the 90 ° swivel the clutch 200 allows. The wings 216 of the coupling parts 202 are on the Side surfaces of the recess 203 a rotary stop (Fig. 2a, 2b). Inside the coupling parts 202 continue in stages, with longitudinal groove-like locking grooves 228 (Fig. 3) can serve the locking in the 90 ° positions.

In the example of FIGS. 5a and 5b, an inclined surface 229 is supported inside the Rotor 40 from a leaf spring 226, which has a locking lug 227. This works with locking grooves 228 of the coupling part 202 together, so that the engagement both in the open Position (Fig. 5a) and in the locked position (Fig. 5b) is noticeable.

From Fig. 1 it can be seen that the driver 50 on the back 51 in the lower region Has punch window 215, which can be coupled to the coupling extensions 19 of the case 15, so that this is retracted or moved forward when the driver 50 is pivoted becomes. There are two punched windows next to each other for mounting on a rebate door provided, while a central punched window on a stump door is sufficient. The evasive movement the driver pin 201 can best be seen from FIGS. 4a to 4d and FIGS. 5a and 5b.

The rotor arrangement according to the invention allows the use of torsionally rigid handles, which can also be in the rotor position let swivel. It can be seen that a rotor arrangement for a fitting system 10, or the like in horizontally intersecting holes in a door, window. is mountable and basically has handles 20 connected to the rotor 40 in a rotationally fixed manner, has an optionally lowerable pin 201 on which a two-armed driver 50 attacks, in the opposite direction to the movement of the return spring, in a cylindrical Housing 30 axially fixed rotor 40 is pivotable to a spring-loaded Trap 15 to operate. The drive connection is through a coupling 200 between rotor 40 and driver 50 can either be manufactured or canceled. For the and locking is a handle that can be fixed on the rotor 40 (rotary links 207, 208). On short arm 54 of the driver 50 effects the coupling or uncoupling by means of the pin 201, which can be raised and lowered by rotating wings 216 of each coupling part 202 is. A rod 206 connects the two coupling parts 202 in a rotationally rigid but axially detachable manner. It sits off-center in a recess 220 and is on a 90 ° bend in the rotor 40 pivotable, the driver pin 201 radially movable in aligned slots 210 A handle core 217 can axially with a face projection 222 of a coupling part 202 can be engaged. The driver 50 is a Sheet metal stamped part with one or two punch windows 215 for hooking in the trap end 19. The housing 30 together with the inserted rotor 40 is on a door, a window or the like. Can be anchored under multiple tensile stress, especially by screwing in different clamping directions.
