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

ROTOR DEVICE FOR A SYSTEM OF BUILDER'S HARDWARE}

The present invention relates to a rotor device for a builder's hardware system according to the preambles of claims 1 and 12.

In the state-of-the-art system described in EP 0 574594 of a fitting member configured for mounting in two intersecting holes of a space closing element such as a door or window, the assembly pre-mounted at the door or window element in the shop is accurately and quickly. In other words, it can prove to be very advantageous to be able to install in 1 minute. The spring biased latch bolt can be retracted by moving an operating element such as a handle or knob to open the door or window. Through the rotor fixed to the handle to rotate with the handle, the movement of the force applied to the handle will pass through the bridge included therein. The gripping portion eccentrically supported in the casing has a pivotable inclined lever shape having two arms of different lengths and is movable in a direction opposite to the direction of the rotor. Short arms typically contact the mating surfaces of the bridge portions, while long arms can be engaged by connecting projections at the rear or inner ends of the latch bolts. When the handle is released, all elements will return to their original position under compression spring force.

Such a builder's fitting system can be fastened by closing the rotor in a sleeve shaped support using a push bar or the like that is rotatably disposed along the handle axis and can be repositioned. However, handles fastened in this manner cannot be pivoted. Since the propensity of the user expects to be pivotable even with the fastened assembly, attempts to operate can easily result in the structure being subjected to heavy loads.

Moreover, experience has shown that, contrary to the known forms described above, a fitting member is required which is adapted to the field mounting of a cylindrical locking device suitable for the owning system and, if necessary, suitable for exchange.

The main object of the present invention is to overcome these disadvantages in addition to other disadvantages and to improve the builder fitting system of the type described above by economic means of reliable and robust design in such a way that simple fastening is ensured and the user's propensity is allowed. . In addition, the elements and element groups can be harmonized and simply replaced with existing fitting systems. An additional object is to achieve a fairly robust attachment of the fitting system when mounted.

The basic features of the invention are described in claim 1. The configuration is the object of protection of claims 2 to 12.

A rotor device for a builder's hardware system configured to mount in two intersecting holes of a space closure element such as a door, window, etc., wherein a sleeve for guiding the latch bolt can be screwed for the operation of a spring biased latch bolt. A rotor comprising at least one handle connected to the rotor to be driven and rotated in two-arm grip means capable of being axially rigidly supported in the cylindrical casing and pivotable in a direction opposite to the rotor receiving a return spring load; In an apparatus, the present invention provides a drive connection selectively actuated or released by a coupling means between a rotor and a gripper means having an arm to engage or disengage the gripping pins according to claim 1. The shape-fitting force applied between the rotor and the gripping means can thus be mechanically interrupted as necessary. The design cost for this device is small. Since the required space is small, it can be favorably employed in the fitting assembly.

The design of claim 2 wherein the gripping pin is radially movable and a design in which the gripping pin is selectively driven in connection with the two-arm gripping means has proven advantageous. In fact, these micro devices cost very little machine cost. In addition, according to claim 3, it would be advantageous if the gripping pin was to be raised or lowered by forced co-rotation of the coupling wing with respect to the rotor bridge. Thus, the gripping pins are functionally matched to the conventional mating surfaces but against the latter fixed shape or position, the gripping pins can be avoided to move.

Further unique features are defined in claims 4-11. The eccentrically positioned bar is connected with two couplings for co-rotation but can be released axially and easily accommodated in tight spaces. The handle is always pivotable in the usual way even during the fastening operation, the gripping pin achieves the lower fastening state parallel to the axis of rotation while not fastening, and the upper part is released because of the connection of the wing side surface.

12. The rotor device of claim 12, wherein the casing is secured under multiple tensions to the rotor securely inserted into a door or window, preferably axially screwing a screwable rosette onto an associated external thread, respectively, and latching bolts within the casing. The sleeve is received by screwing radially, the casing having an external screw protruding on one side and arranged in mirror symmetry and oppositely tapped to screw into a single rosette each for a shape-fitting engagement with a door or window lamp. Have

Other features, features and advantages of the invention will be apparent from the embodiments described with reference to the claims and the following figures.

3 is an exploded perspective view of the coupling means.

4A-4D are front views of the rotor device in various positions.

5A and 5B are enlarged front views of the modified rotor device in the unlocked and locked positions.

The component parts of the fitting assembly 10 are shown in FIG. The design generally corresponds to the design of the locking system described in WO 93/25788 A1. The latch bolt 15 is loaded by a compression spring 16 and guided into a sleeve 18 insertable into a longitudinal hole (not shown) of the door. The rotor 40 connected to the fitting handle 20 can be installed in an intersecting transverse hole, the main function of which is to engage the spring bolt-loaded latch bolt 15 through the coupling protrusion 19 when the handle is operated. To retreat.

According to the invention, the force applied to the handle 20 will be transmitted to the rotor 40 coupled to rotate therewith and act on the pin 201 inside the rotor 40. The short arm 54 of the grip 50 provides a support on the pin. The gripping portion rotates in the opposite direction of the rotor 40 and engages the long arm 52 and the coupling protrusion 19. Upon release of the handle 20, all the component parts return to their original position under the force of the compression spring 16. The spring 34 is received in or in the rotor 40 divided horizontally by the symmetrical center plane. The rotor can thus be inserted axially into the casing 30 which is also mirror symmetrical and has suitable openings 35 on both sides. The side portion 48 of the rotor 40 includes a rotation stop 47 and a bayonet lug 49. A corresponding bayonet recess 123 is provided in the inner end face 191 of the handle 20.

The casing 30 is generally cylindrical and has external threads 214 on both ends. The gripping portion 50, ie the punched sheet metal element, is pivotally mounted to a pivot bolt 53 which is parallel and eccentric to the axis of the casing 30, and is rearwardly extended as a long arm 52. The short arm 54 with 51 is bent from the rear portion 51 for the side having a hole for the pivot bolt 53.                 

The handle 20, which is connected to rotate with the axially bolted rotor 40, has either a rotary trunnion 207 (at the top right of FIG. 1) or a cylinder lock 208 (at the bottom left of FIG. 1). A handle throat hole 209 that can be inserted axially.

Each of these elements has an axial parallel tongue 230 that engages the coupling means 200, the structure of which is shown in FIG. 3. Coupling means 200 comprise two coupling portions 202 each having a wing portion 216 and an outer square bolt 221. The outer square bolt 221 includes a tomographic portion 219 that interacts with the protrusion 222 of the core 217 that houses the centering stud 224 of the coupling portion 202 in the shaft hole 223. Both coupling portions 202 are connected to co-rotate by bars 206, in particular square bolts. A gripping pin 201 that is radially movable within the extension hole 210 is provided to frictionally engage the gripping portion 50. In the released state of the fitting system shown in FIGS. 2A, 4A and 5A, a gripping pin 201 having a preferably cylindrical cross section will be placed on the outer circumferential surface of the wing portion 216 of the coupling portion 202. They are countersink with respect to the end face of the rotor 40 and are mirror symmetric. When handle 20 is actuated, grip 50 retracts through short arm 54 (FIG. 4B) such that long arm 52 of grip portion retracts latch bolt 15 through coupling protrusion 19. Pivot is possible.

Sides of the fan-shaped reinsertion 205 of the coupling portion 202 protruded axially on both sides of the rotor 40 and co-rotated by a square bar 206 so that they always move together in a cooperative position. Form a solid rotational stop for the wing side 204. The actuating means 207, 208 extending through the handle neck hole 209 of the handle 20 may be engaged with the outward tip of the coupling portion 202, respectively.                 

From the original position shown in Fig. 2a, the rotation of the coupling means 200 from the original position of Figs. 2b, 4c and 5b follows the extension hole 210 of the rotor 40 with the gripping pin parallel to the axis of rotation. The two radial supports are removed from below the gripping pin 201 to fall. When the handle 20 is now actuated, the pin 201 will reach within the cavity (see FIG. 4D), thereby leaving the grip 50 and the latch bolt 15 in their original positions. Thus, in contrast to the prior art, the assembly can be blocked even though the handle 20 can be pivoted.

When the coupling means 200 is rotated 90 ° in the opposite direction, the wing side 204 raises the gripping pin 201 to return to the upper original position on the periphery of the coupling wing 216 (FIG. 2A). . The pin 201 then reengages with the short arm 54 of the grip 50, and when the handle 20 is actuated, the latch bolt 15 will retract.

It is possible to insert the actuating means (each of the trunnion 207 and the cylinder lock 208) through the handle neck hole 209 so as to be flush with the handle and to axially insert into the fitting unit 10 in the assembly position. . The tongue 230 is coupled to the inside of the rotor 40 through a hole 211 allowing the fixing of the tongue 230 by the countersink screw bolt 212 (see FIG. 1). The protrusion 222 of the actuating core 217 is thus connected to interact with the exterior 221 of the coupling 202.

Unlike similar conventional fitting systems, unit 10 is firmly secured to door metal foil (not shown) by multiple screw tensions. To this end, the two threadable rosettes 213 (of FIG. 1) are provided with the oppositely tapped outer thread 214 of the casing 30 in which the sleeve 18 can be threaded radially by its screws 37. Screwed on both sides of the phase. These three screw engagements firmly clamp the front end of the door to the correct position by acting to introduce tensile stresses in various directions into the casing 30.

The trunnion 207 may be arranged to be shaped as a longitudinal axis inner rectangular appearance (see FIG. 2) on the outer square 221 of both coupling portions 202, while the cylinder lock 208 is in the direction of rotation. Will require idling. However, if the opposing door sides are locked or unlocked, they do not rotate. It can be seen from FIG. 3 that the opposing protrusions 222 of the core 217 are quadrant sector shaped. A shaft hole 223 or center hole in the core 217 serves to receive a centering stud 224 facing the coupling. Coupling portions 202 facing the body portion of the semi-circular cross section each have a flat surface 225 to axially engage the quadrant sector 222 of the core 217 so that the coupling 200 pivots. The wing portion 216 of the coupling portion 202 meets the rotation stop of the side of the recess 203 (FIGS. 2A and 2B). On the inner side, the coupling portion 202 cascades with a longitudinal pleat or stop groove 228 that serves to lock in the 90 ° position (see Figure 3).

5A and 5B, the inclined surface 229 inside the rotor 40 supports the leaf spring 226 having a locking lug 227 that interacts with the stop groove 228 of the coupling portion 202. .

As shown in FIG. 1, the lower region of the rear portion 51 of the grip portion 50 includes a punching hole 215 that engages with the hook protrusion 19 of the latch bolt 15 so that the grip portion 50 is formed. The latter retracts or advances when pivoted. Two adjacent punched holes are provided in the rabbit door, whereas for the flush door, one center punched hole will be provided. The disengagement or avoiding motion of the gripping pin 201 is well illustrated in FIGS. 4A-4D and FIGS. 5A and 5B.

The rotor device of the present invention allows the use of a handle that can be pivoted even when the rotor 40 is locked, although the handle is rigidly connected to rotation. The rotor device for the fitting system 10 may be mounted in horizontally intersecting holes of doors, windows, and the like, and includes a handle 20 that is non-rotatively linked to the rotor 40 and configured to be selectively repositioned. The pin 201 is stored. The pin 201 is coupled to the two-arm grip 50, which is axially defined and supported in the cylindrical casing 30 to actuate the spring biased latch bolt 15 and the return spring. It may be pivoted in a direction opposite to the movement of the loaded rotor 40. By the coupling means 200, the drive connection between the rotor 40 and the gripping portion 50 can be interrupted or connected as necessary. The actuation means (trunnion 207), which can be attached to the rotor 40, acts to be released and locked, respectively. The short arm 54 of the grip 50 provides engagement or separation as the pin 201 rises or falls as the wing 216 of both couplings 202 rotates. These two couplings 202 are connected via a rod 206 in a manner that is co-rotating or axially detachable. The rod 206 is eccentrically disposed in the recess 220 and can pivot about a 90 ° arc in the rotor 40 that guides the gripping pin 201 to radially move within the aligned extension hole 21. have. The actuating core 217 may be axially displaced to engage the opposite end protrusion 222 of the coupling portion 202. The grip 50 is a punched sheet metal element with one or two holes 215 for hooking to the latch bolt end. The casing 30 comprising the mounted rotor 40 can be fixed to a door or window or the like under multiple tensions, in particular by means of threaded engagement providing different tensile stress directions.
