Abstract

The motor-powered articulated mechanism, to open/close a fanlight window or flap, has a longitudinal housing (1) to accommodate a drive and the articulated mechanism. A grip (40,40a) which is opened for release of its hold in or around a pin (Z), installed in the gap (12) between the window pane and the frame, acts on an opening/closing rod (49) for the window. The grip assembly is near the housing, and projects from it. The operation is through a wall nut on a spindle. A coupling is between the nut and a push member, to allow rotation (R) of the nut against the push member. The push member has an arm (40) to operate the rod at the window for the opening or closing movement.

Description

The invention relates to a scissor assembly according to a of independent claims 1, 2 and / or 3. Such Scissor arrangements have a folding scissors for actuation of wings, especially fanlight wings that are not easy on accessible places must be operated, i.e. opened and must be closed.

Motorized scissors are not unknown as such, for example described in DE-B 197 28 713 (W. Hautau) . and EP-A 710 759 (W. Hautau) mentioned therein . Two arms are connected to one another in an articulated manner, an electromotive drive being placed in the housing of one arm, which enables the opening movement and the closing movement of the two scissor arms. In order to allow a tilting movement or compensating inclination movement of the scissor arms relative to one another, that is to say perpendicular to the plane of the scissor arms, multi-section scissors are used which have sufficient play in the joints or can be pivoted about an axis of actuation. Such multi-section scissors usually have three articulation points, one of the main scissor arm, one of a control arm and one of an actuating element, one of the points being displaced in the longitudinal direction by an actuating rod and the other joints and the scissor arms being adjusted in accordance with this movement.

It is an object of the invention to propose a compact arrangement of motor-operated scissors that is easy to assemble. It should also have a low design, be cost-saving and have the possibility of achieving an additional locking or even locking of the wing via a linkage which is provided on the actuated wing, without an actuating handle on the wing of this actuating linkage used for locking purposes in the longitudinal direction shifts.

This is achieved with at least one of the independent ones Claims 1, 2 and / or 3 or 13 or 18.

The scissor arrangement has a locking arrangement (as an engagement arrangement) so that they in the course of the housing length is arranged, emerges from the housing and is shaped such that it can intervene in the rebate area. The scissor assembly, the is held and stored in the housing, is laterally, especially above the wing at such a distance from Folding space arranged that the locking arrangement in the Folding space between the frame and sash with one arm is able to intervene and thereby one during its longitudinal movement Can capture control pin and operate in the longitudinal direction. at an opening of the wing is first the pin of the Arrangement by the motorized operation of the scissors in the initial idle stroke actuated to then at the Opening movement of the wing to release the pin. In the The closing movement is reversed. First the pin is gripped when closing and then in the course of the Idle stroke (of the scissors) in the longitudinal direction for locking (on Wing) moved.

The locking or additional locking is via the Actuating or locking linkage (also locking linkage called) reached, there usually provided pin in lock pockets on the frame with a bolt position intervention.

A first locking can be done by the scissors arrangement itself can be achieved with the traction the wing to the Frame presses. However, this first locking is usually sufficient with regard to the required closing force or Not uniformity along the length of the wing being operated off, so that an additional lock on the locking linkage and arranged along the length of the wing Locking pin helps.

If corner drives are used, the locking linkage can be used also extend around the corner of the wing, so that also in the vertical rebate plugs can be provided that of the scissor assembly over that described Intervention arrangement, starting from the case bottom over the Closure linkage are operated.

The motor and the hinge brackets of the hinge points of at least an opening scissors and a spindle rod are in one common housing arranged (claim 2). In the course of The spindle rod is continuous in the housing, so it does not require any Coupling pieces and is therefore easy to assemble. The assembly on the frame is done by fixing the housing with the Motor and scissors at the same time, with a few simple steps and few screws the exact placement and a good one Alignment of the hardware stay in the housing is possible becomes.

Due to the combination of a longitudinal stroke movement for the pin of the actuating linkage and an opening movement of the Scissor arms that tilt or tilt slightly Allowing lowering of the wing when opening is allowed a compensation device is provided, the rotational movement of the the scissors-driving walking limb allowed without the Additional locking in its position perpendicular to the frame change. The scissors are actuated via the Traveling mother, the same traveling mother over a (circumferential) loose coupling with the one reaching out of the housing Locking arrangement is coupled (claim 3.13).

The coupling takes place via a sliding link, which is at the bottom of the Housing is guided (claim 6). The sliding link can be designed roof-shaped (claim 8), it being in a tendon-shaped recess of the traveling nut engages.

A relative swiveling of the traveling nut around its axis, in the the spindle rod is arranged, brings the tendon-shaped Recess with its flat bottom (claim 9) in relative positions to the roof-shaped training. The wedge-shaped surfaces lie either left or right in the end position near the level Floor and can be seen through their wedge bevels (which run flat) the maximum deflection stroke (the angular limit angle) of the Define traveling mother.

The engaging arrangement as a locking arrangement has angled Shape, for engaging in the rebate space between the flap of the wing and the frame on which the scissor assembly is firmly attachable (claim 7).

There can be two or more scissors in a common housing be arranged, a central drive is provided (Einfensterlösung). Here is a long spindle rod coupling element of the scissors. Can also be coupled via a tubular spacer that rotates one over the Spindle driven nut connects to the next nut which operates the next pair of scissors. The intermediate tube turns not for the longitudinal movement, but couples the thrust movement on the next - and also more - scissors (claim 18).

Likewise, two or more (spaced) single scissors sequentially coupled with a pipe (a profile), wherein the drive is only located in a pair of scissors (multi-window solution). Here the tube can be used as the traveling nuts of the several scissors Connect the thrust piece and insert it axially into the moving links his.

In order to couple the pipe as a profile to the respective traveling nut, (Axial) recesses can be provided in which the Tube is inserted or inserted with its end piece (Claim 19).

1 and 2 show a multi-section scissors in the open and closed state. An essentially rectangular scissor body 1 receives a drive unit 2 which actuates a spindle rod 3 in a rotating manner. The spindle rod 3 extends up to the scissor members, or the section in which the scissor assembly is placed. The housing 1 is designed continuously between the scissor section and the motor section. There is an assembly point 71, 70 at each of the two end sections.

The spindle rod engages with its spindle (its thread) the thread of a spindle nut 4, which is longitudinally displaceable in Housing 1 is arranged. You have the opportunity to take care of yourself certain angle to make a compensatory movement of the Scissor arms of the multi-section scissors when the To allow the wing (during its opening movement).

The spindle nut moves one via a connecting piece 31a Articulation point 31, at which an actuating member 5 is pivotally arranged is via a slot / pin connection (or several such connections) operated a control arm 6, wherein in an empty stroke path 61 is provided for the web guide. The Control handlebar is on a fixed, immovable Articulation point 32 articulated on a support frame 9 and engages at its other end to the extendable scissor arm 7, the on a further articulation piece 8 as a further trestle over a further joint 30 is articulated, the Joint piece 8, the traveling nut 4 and the articulation piece 9 along an axis 20, which runs in the spindle rod 3, placed are. The articulation piece 8 can be moved in the longitudinal direction, is therefore not coupled to the thread of the spindle rod. The Traveling nut 4 can only be moved when the spindle rod is turns, so its thread is in turning engagement. The Articulation point 32 on the support frame 9 is immovable.

If the spindle nut (the "traveling link") moves, move it the two inner links 5 and 6 move the second one Arm 7, guided through the scissor element 8 to the left in the closed position (cf. FIG. 2). The dash-dotted Line 7a shows the extendable arm 7 in the closed Position.

The extension arm has a wing coupling point 10, which is designated 10a in the closed position and which moves away from the frame B in the direction H perpendicular to the extent of the housing 1 in order to open the wing F. The wing coupling point 10 is attached to the wing F via a wing bracket 50, as shown in FIG .

During the closing movement or the opening movement can the scissor arm 7 in a released direction R and back move, pivoting about the axis 20. A slot 25 is at Housing 1 provided to the handlebars 5, 6 and associated articulation points 31, 32, 30 to a push-through gain. All three pivot points 30, 31, 32 can around Swivel axis 20 to a limited extent. Only the hinge point 32 keeps its longitudinally determined position during an opening movement and a closing movement. The articulation points 30 and 31 are along the axis 20 when the spindle rod 3 and a drive by the motor 2 longitudinally displaceable.

The closed state with the same reference numerals is in Figure 1 shown. The engine is located on the left here, runs via a coupling area to the spindle rod 3, which the Hiking nut 4 actuated.

In supervision, an additional locking device as an angle piece 40 is closed recognize that with the spindle nut in a closer to is descriptively coupled. The reference numerals from Figure 1 correspond to those described above for Figure 2, so that they will not be discussed again here. noted should be to Figure 1 but that the handlebar 5 in the Sectional view is not shown, only a pivot point 31 the traveling nut 4 can be seen.

A coupling 40, which can be screwed to the spindle nut 4 and has a slot 40a which opens to the side, enables the locking or additional locking to be actuated. It takes place via the coupling point 40, Z, where Z is the pin of a locking linkage 49, as shown in FIG. 4 .

During the idle stroke 61 of the scissors by engagement lateral opening of the elbow 40 around the pin Z one releasable clutch reached, which allows longitudinal actuation, when the wing is closed. When opening, the Pin Z against the closing direction to the opening direction moves, with other locking pins on the linkage 49 the Release the lock and the sash when it starts to open of the scissor arm 7 is issued.

In the end positions, the system has a mechanical one internally Stop, and the motor is switched off off.

Screw fastenings 70, 71 are shown in FIGS. 2 and 3 and 1 seen. They are designed to be an additional one Alignment to the wing is possible, for which elongated holes in two Directions are provided.

Due to the compact design and the related structure of Motor and scissors significantly reduce the assembly time. The Components engine, scissors, scissor holder, linkage and coupling do not need to be assembled separately in a specific sequence and can be positioned, rather, by a single Positioning all components the correspondingly correct one relative position and the orientation to the wing and the wing bracket 50 are observed.

The engagement of the angular engaging piece 40 is for Locking in the closed position shown in Figure 3. It engages in the folding space 12 in the closed position. The Position before reaching into the pin Z or reaching around of the pin Z is illustrated in Figure 4. At a decreasing distance H moves the angular Intervention piece 40 with the traveling nut 4 so that it is correct aligned - when the wing F strikes the Frame B (at H = zero) the pin Z (at least one piece) engages and then during the idle stroke path 61 (corresponding to the recess in parallel to axis 20 in one of the links) a longitudinal movement x of the drive rod 49 triggers, which is arranged under a cover rail 49a.

The coupling of the angular locking piece to the pin Z is explained in a large enlargement in FIGS. 5 and 6 and 6a . The traveling nut 4 can be seen with the hinge point 31 on a formation 31a. Likewise, the axis 20. There is a loose coupling between the traveling nut 4 and the angle piece 40 protruding from the bottom of the housing 1, which can be seen in the section in FIG. A roof-shaped intermediate piece as a sliding member 41 is fixed (via a screw connection) to the angular locking piece 40. The roof-shaped member has a flat angle between 140 ° and 160 ° and engages in a tendon-shaped recess 4a. The traveling nut 4 can thus perform a limited pivoting about the axis 20 without the angle 40 having to take over this pivoting movement or pivoting through it. In the longitudinal direction, the coupling takes place via the axial edges of the recess 4a (above and below the paper plane of FIG. 6), in order to transmit a pushing movement to the angle piece 40 with its recess 40a for engagement in the pin Z on the drive rod 49. This close coupling shows Figure 5 in supervision.

The penetration of the angle piece 40 through the bottom of the housing 1 is explained in FIG. 7 . The bottom of the housing 1 is recessed approximately in the middle, a slot 1c being formed through which the connection point between the angle piece 40 and the sliding member 41 extends. The sliding piece 41 is guided in the housing, the remaining pieces 1b of the base taking over the guidance to the frame.

A cut-out 1a on the bottom of the housing ensures a possible passage of section 40b of the elbow between the housing and the frame, this side and beyond the maximum sliding path of the angle piece 40 a greater floor thickness of the housing is provided to the free space for the thickness of the elbow 40 in its section 40b to maintain its longitudinal motion. Section 40b projects so sideways out.

A clearance through the milling, perpendicular to the extension of the Soil 1b and the surface of the frame, is low that too large a pivoting of the angle piece 40 relative to the Frame or in relation to the remaining floor 1b is not allowed, what through the free (loose) coupling and the roof-shaped Forming the sliding piece 41 to the traveling nut 4 is reached.

The traveling nut 4 is at the other end with the handlebar linkage extension 31a provided, which fixes the articulation point 31. All other reference numerals of Figures 7 are also from the other figures recognizable, so that no closer to them to be received.

In the area of the handlebar linkage extension 31a is (symmetrical arranged) a circumferentially limited Elevation 4b is provided, which is formed on the traveling nut. This has stepped shoulders on both sides with the following Purpose, the extensive pivoting movement of the traveling mother too limit.

Usually a traveling mother is not extensive pivoted out or stored to them only in the longitudinal direction with a spindle rod and a rotary movement (motor, Spindle rod, drive) in a longitudinal movement (opening movement, Scissor actuation or relocation). The Lowering movement of the wing F described above in a Exhibiting movement H, represented by the vector representation R in FIG. 3, the traveling nut 4 can be rotated slightly circumferentially, the extension 31a protrudes through the gap 25 and one Angular swivel movement of a few degrees (up to 10 ... 20 Degrees) allowed. Paragraphs 4b 'and 4b " allow the traveling nut to be supported on the inner contour or the inner surface of the housing to the forces on the Limit or limit spindle rod.

The slot 25 leads to the loss of guidance for the one side Traveling nut in a profiled housing. When the Extension 31a in the direction described above would Spindle 3 are loaded radially. So that there is this burden does not come, or the burden is kept within limits at an angular distance of between 40 ° to 50 ° from the plane, in which the extension 31 is located, step-shaped shoulders are provided. One of these paragraphs would suffice, but for one symmetrical solution, both paragraphs can be provided. With These paragraphs are supported by the traveling mother in one extensive movement on the inside of the profile.

From the sectional view of Figures 7 (right part) is the gap 25 previously described in FIG. 3 is clearly visible, through which the extension 31a of the walking member 4 engages as well the other hinge brackets 8 and 9, as previously described, wherein the hinge bracket 4 as a traveling nut, guided on the spindle 3, is trained.

The opposite gap 1c for reaching through the connection point between the angle piece 40 serving as an engagement arrangement and the sliding member 41, which connection is rigid, can be seen more clearly in FIG. 7a . FIG. 7b illustrates the intervention 41 / 4a from a different point of view.

A coupling piece as a profile tube can so on the traveling nut 4 be plugged on, as in Figure 6 by axially free-standing Openings 4f, which extend partially around the circumference, are shown. This Sliding piece is used to transmit a pushing movement of the Hiking link 4 to other hiking links, which are then not included operated by a spindle, but via the coupling piece.

This coupling tube can be in the long run extending housing extend to multiple scissors actuate. This coupling tube as a profile can also over an existing space between adjacent Scissors extend to one outside of the scissor housing (Axial) drive stroke conveyed by the rotary motion a spindle of only one traveling member in a scissor housing is initiated.

The coupling piece K, which is used schematically in FIG the end face of the traveling member 4 is outlined by a clamping device, represented by one in the thread guided screw 50 with a front tapered Mandrel shoulder 50a, held. To the described coupling tube not only to clamp, but also to hold on tight small mandrel shoulder 50a under pressure in the tube material of the Penetrate the coupling piece, so also axial forces to be able to transfer (positively). Other clamping devices are also possible. The described screw device with material-displacing mandrel is not the only one Possibility.

To guide the hiking link 4 in the housing profile are still the lateral guide portions 4c, 4d mentioned that are arranged opposite one another. They are in the shape of the Adapted traveling nut, allow their longitudinal movement and also whose pivoting movement, which was previously described, is limited by the shoulders 4 ', 4 "of the upper neck 4b near the Extension 31a. The recess 4a is opposite the extension 31a provided that receives the sliding member 41 and a loose Represents coupling to enable the limited Pivoting movement. The swiveling movement can be increased if the sliding member 41 is roof-shaped. In The sliding member 41 essentially engages in the longitudinal direction a perfect fit in the recess 4a, so that hardly, if not there is no game. The longitudinal movement of the traveling nut 4 can so their accuracy can be improved.

Section 40b as an arm of the angular Intervention arrangement 40, with arm 40b and perpendicular to it Recess 40a in the angled arm section, is in guided a recess 1a of the housing, which is a partial removal can be a wall of the housing profile 1. In addition is a Gap also provided here, which with 1c the penetration of a Screw arrangement allows to fix the Slider 41 on the arm. The remaining wall serves on both sides and as a sliding bearing for arm 40b and that Sliding member 41. The moving member 4 is inside the housing included and guided with bearings 4c, 4d.
