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 arrangement for a system ironwork.

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

In a modern hardware system according to the EP0574594 that can be mounted on two cross drills of a constructive element of room closure - a door, a window or similar - it has been shown that it is especially advantageous that a factory-assembled hardware module can be installed shortly time, for example in less than 1 min, exactly in the element of Door or window. When operating a drive element, for example a handle, a button or similar, a trigger loaded by a spring, so that the door or the window can be opened. The flow of force is produced starting from the handle, through a rotor joined in a non-rotational way with it, towards a bridge contained in East. A drag housed eccentrically in the housing is configured as a rotating lever with two different arms length; it moves in the opposite direction to the rotor. Shortest arm conventionally rests on a bridge contact surface, while the long arm is in gear with appendages of coupling at the rear end (inside). When you release the handle, all components move to their initial positions under the pressure spring action.

This type of hardware systems can be closed in such a way that the rotor is locked in its housing in the form of bushing, for example with a pin arranged on the axis of the handle, which can be operated by translation or by movement Rotary The handle closed in this way, however, is not can turn Since the user starts from the turning capacity, even of closed systems, when trying to operate them they can heavy loads frequently occur that must be absorbed for the construction

In addition, it has been shown that there is a need of being able to mount in the fittings of this type closing cylinders suitable for closing devices and, if necessary, replaceable, which with the systems mentioned so far was not possible.

An important objective of the invention is to overcome these and other inconveniences of the state of the art and improve a hardware system of the type mentioned with economic means and clear form from the constructive point of view, and with a design stable, so that the possibility of a comfortable closure taking into account the habits of the users. Also, the components and modules must be compatible with the existing hardware systems and be able to be replaced so simple. In addition, an especially fixed seat of the mounted hardware system.

The essential features of the invention they appear in claim 1. Some configurations are subject of claims 2 to 12.

In a rotor arrangement for a system of hardware that can be mounted on two holes, which intersect horizontally, from a door, from a window or similar, presenting at least one handle non-rotatably connected with the rotor, with a drive joint with a two-wheel drive arms that can be operated by a spring loaded trigger rotate in the opposite direction to the movement of the damped rotor by a recovery spring, and with a substantially cylindrical housing which houses the rotor axially fixed and in which you can screw a bushing transversely to the rotor shaft carries the trigger, the invention provides, according to claim 1, that the drive joint between the rotor and the drive can optionally established or canceled by means of a coupling, the dragger having an arm that can be engaged in gear or out of gear with a drive pin. That is, according to the need, the flow of force acting in drag between the rotor and the drag can be optionally interrupted mechanically. The constructive expense of this provision is low; thanks to the little space required, the hardware module.

It is advantageous to configure the claim 2, according to which the drive pin can be attached radially mobile and optionally with the drag carried out with two arms. The disposition extraordinarily space saving requires an expense especially low constructive. It is also advantageous that the drag pin according to claim 3 can be raised and lower with respect to the rotor shaft, namely by a turn obligatorily simultaneous wings of each piece of coupling The operation of the drag pin corresponds to the conventional contact surface, but contrary to the Rigid shape or position of this can give.

Other convenient configurations are indicated in claims 4 to 11. The eccentric arrangement of a rod that joins the two coupling parts rigidly to the turn, but axially separable, allows a good accommodation even In a small space. During closing, the drive pin it can arrive parallel to the axis of rotation in a position of lower closure, while during opening it returns to a upper position of release by surface attack lateral wings. Therefore, each handle is swivel of the usual way.

The rotor arrangement according to claim 12 is characterized in that the housing inserted together with the rotor in the door or window can be anchored in it while multi-wired, preferably by screwing axial of a threaded rosette on antagonistic outer threads assigned and by screwing the trigger bushing into the Case. In this way, a triple cable tie is achieved and therefore an extraordinarily fixed seat that permanently resists high requests.

Other features, details and advantages of the invention result from the claims and from the following description of embodiments with the help of the drawing. They show:

Figures 2a and 2b an inclined view of a rotor arrangement in open and closed position,

Figure 3 an inclined developed view of a coupling,

Figures 4a to 4d front views of a rotor arrangement in different positions and

Figures 5a and 5b enlarged front views of a modified rotor arrangement, in the open position and closed.

In figure 1 the components of a hardware unit 10. Its structure generally corresponds to a hardware system described in WO93 / 25788A1. A trigger 15 is loaded by a pressure spring 16 and is guided in a trigger bushing 18 that can be inserted into a drill longitudinal (not shown) of a door. In a drill cross section that can be attached to a rotor 40 attached with handling elements 20 of the hardware. The main function consists of removing the trigger 15 loaded by a spring in coupling appendages 19 when the elements of driving.

According to the invention, the flow of forces is produced from the handle 20, through the attached rotor 40 of rigid torsional shape with it, on a pin 201 located in this one, on which a short arm 54 of a drag can be supported 50 that rotates in the opposite direction to rotor 40 attacking with one arm length 52 in the coupling appendages 19. After releasing the handle 20, all components move again under the action from pressure springs 16, 34 to their initial positions. The springs 34 are housed in or inside the rotor 40. This is transversely divided into its central symmetry plane, being able to therefore axially inserted into a housing 30 also inverse symmetric, which for this purpose has openings 35 to both sides. Side portions 48 of rotor 40 are provided with stops of turn 47 and bayonet appendages 49. On the front sides interiors 191 of the handles 20 there are bayonet cavities 123 corresponding.

The housing 30 generally has a cylindrical shape. At its two ends it is provided with outer threads 214. eccentric with respect to the axis of the housing 30 and in parallel there is a housing bolt 53 therein. swivels 50, specifically one piece stamped sheet metal with a spine 51 that down continues as long arm 52 and from which angular arms come out short arms in side side shape 54 with bolt holes accommodation 53.

With an axially threaded rotor 40 you can join non-rotating handles 20 with holes handle neck 209 in which it can be inserted respectively axially a rotary knob 207 (figure 1, top right) or a closing cylinder 208 (figure 1, bottom left).

An item of this type is provided respectively with an axially parallel tongue 230 acting in set with a coupling 200. Its structure is represented in Figure 3. It has two coupling parts 202 presenting respectively a wing 216 and an outer square 221. The latter it has a step 219 that acts in conjunction with a projection 222 of a core 217 receiving in an axial bore 223 a pin of centered 224 of coupling 202. The two coupling parts 202 are rigidly attached to the rotation by means of a rod 206 which is especially a square spike. For closing force towards the drag 50, a drag pin is provided  201 radially movable in oblong holes 210. In the system of fitting not closed according to figures 2a, 4a and 5a, the tang of drag 201 of preferably cylindrical cross section circular lies on the contour of the wings 216 of the pieces of coupling 202 that are embedded symmetrically to the reverse on the front surfaces of the rotor. Through the short arms 54 of the drag 50, this can be rotated (figure 4b), so that its long arm 52 causes, through of the coupling appendages 19, the removal of the trigger 15 to operate the handle.

Depressions 205 form twist stops solids for side surfaces 204 of the parts coupling 202 projecting axially on both sides of the rotor 40. These are joined together in a non-rotating manner by the spike square 206, so that the two always rotate compulsorily and congruently. At both ends of the coupling parts 202, facing out, the elements 207 or 208 rotary operating units can be coupled through the holes 209 in the neck of the handles 20.

Starting from the connection status according to the figure 2a, a rotation of the coupling 200 to the angular position according to the Figures 2b, 4c and 5b, take the drag pin 201 its two radial supports As a result, it falls down on both oblong holes 210 aligned with each other of rotor 40, in parallel to the axis of rotation of this one. When the handle is operated, pin 201 is moves in a vacuum (figure 4d), so that the drag 50 and the trigger 15 remain in their initial positions. In this position, the hardware system is closed, but unlike the State of the art allows the rotation of the handles 20.

If coupling 200 is rotated 90º in in the opposite direction, the lateral surfaces 204 of wings return to lift the drag pin 201 to its upper initial position where it rests on the contour of the coupling wings 216 (figure 2a). Then, pin 201 is again engaged with the short arm 54 of the drag 50 so that, when the handle, trigger 15 is removed.

The operating elements (rotary knob 207 or closing cylinder 208) can be inserted axially in the unit of hardware 10, through the holes 209 of the handle neck, of flush shape with the handle, which can also be done in construction In the handle languages 230 are provided 211 step drills that allow tongue immobilization 230 inside the rotor 40, for which they are provided countersunk head screws 212 (figure 1). In this way, the 217 handle cores are in active action, through their projections 222, with the outer parts 221 of the couplings 202.

Unlike hardware systems conventional, comparable, the unit 10 is fixed, by means of a multi-threaded by screwing, to a door leaf (no represented). Two threaded rosettes 213 are used for this (figure 1) which are screwed from both sides on the external thread 214 housing antagonist 30, in which it can be screwed radially the bushing 18 with a thread 37. Each of the three threaded joints introduce tensile stresses of different directions in the housing 30, so that it is secured safe and in the correct position at the door.

While the rotary knobs 207 can be put with a longitudinal profile with inner square (see the Figure 2a) in drag on the outer square 221 of coupling parts 202, closing cylinders 208 they need a freewheel in the direction of rotation; is that on the side not operated the door does not rotate when it closes or opens in the opposite door side. Figure 3 shows that the projection 222 front of the core 217 is configured for this as a sector of quarter circle A central hole or an axial bore 223 in the core receives the centering pin 224 on the side of the coupling Both coupling parts 202 have a flattening 225 of semicircular cross section, which in the axial gear with quarter circle sectors 222 of the cores 217 always allows the 90º rotation of the coupling 200. The wings 216 of the coupling parts 202 are found in the side surfaces of cavity 203 a rotating stop (figure 2a, 2b). Inward, the coupling parts 202 continue from staggered shape, can serve retention slots 218 in shape of longitudinal grooves (figure 3) for interlocking in the 90º positions.

In the example of Figures 5a and 5b, in a oblique surface (229) inside the rotor 40 rests a crossbow 226 having a retention heel 227. This acts on set with retaining slots 218 of the piece of coupling 202, so that the interlocking is noticeable both in the open position (figure 5a) as in the closed position (figure 5b).

In figure 1 it is seen that the drag 50 has on the spine 51, in the lower area, stamped windows 215 that are can be coupled with the coupling appendages 19 of the trigger 15, so that in case of a turn of the drag 50 they are removed or move forward. For accommodation in a lace door two stamped windows are provided next to each other, while a flush stamped window is enough central. The deviation movement of the drive pin 201 it is best seen in figures 4a to 4d and in figures 5a and 5b.

The rotor arrangement according to the invention allows the use of rigid torsion handles that can be made also rotate in the closed position of the rotor. It looks like a rotor arrangement for a fitting system 10 that can be mount drills that cross horizontally from a door a window or similar and which generally has 20 handles attached non-rotating with rotor 40, it has a pin 201 which is it can optionally lower, in which it attacks a drag 50 of two arms that can be turned counterclockwise rotor movement 40 damped by recovery spring and housed axially fixed in a cylindrical housing 30, for actuate a trigger 15 loaded by a spring. Through a coupling 200, the drive joint between the rotor 40 and the Drag 50 can be set or canceled optionally. For opening and closing serves a handling element (rotary knob 207, 208). A short arm 54 of the drag 50 causes the coupling or decoupling via spike 201 that can be raised and lowered by turning the wings 216 of each coupling piece 202. The two coupling parts 202 are rigidly connected to the turn, but axially separable, by a rod 206. It is located off-center in a cavity 220 being able to rotate in an arc of 90º in the rotor 40 that carries the radially mobile drag pin 201 in oblong holes 210 aligned. A handling element core 217 can be engaged axially with a protrusion 222 of the front side of a piece of coupling 202. The drag 50 is a stamped sheet metal part with one or two stamped windows 215 to hook end 19 of the trigger. The housing 30 together with the inserted rotor 40 is it can anchor in a door, a window or similar under a tension traction manifold, that is, by means of threaded joints in Different senses of tension.
