Description

The present invention relates to a limiting scissors for one in one Frame, turn, tilt and turn or tilt sash, consisting of at least from a pair of limiting scissors at one end in a guide part and at their other end in a fixed scissor-type bearing block each pivotable is mounted, the guide member being longitudinally displaceable in a guide groove is guided and has a braking device.

Limiting scissors for a rotating, tilting or arranged in a frame Tilt-and-turn blades are known as such. They serve to limit the rotation or Tilt range, so generally the pivoting movement of the wing in question, mostly 90 °.

Such limiting scissors - also known as folding scissors - is for one in a frame arranged turn, turn-tilt or tilt-turn sash from the DE 44 07 245 became known.

The known limiting scissors have bearing eyes at their ends, each on a pivot pin of the scissor bearings are pivotally mounted. A first hinge pin is each part of a frame side and a second hinge pin part of the wing side Scissor bearing. The position of the scissor stay is determined using a template set up and then for the purpose of pre-assembly by hammering into the frame anchored, with a cutting edge attached to the underside of the scissor bearing cuts in the casement or frame. Then the anchorage takes place Scissor stay using screws to be screwed into the frame or window frame.

The known folding shear is made in two parts, the two telescopic parts each have a curved groove in which a holding pin slidably slides. The Curve groove also has notches in which the retaining pins when passing through the Intervene in the curve groove and achieve a braking effect.

In the known folding shears, on the one hand, the assembly is cumbersome and time-consuming and on the other hand, by driving the scissor stay into the frame and Window frames slightly damaged. The local damage can be caused by climatic influence lead to unnoticed erosion of the frame. The erosion can undetected affect the strength of the screw connection so that it can solve suddenly. In addition, they are expensive to transport Take security measures and pay special attention to small parts dedicate, as these are easily lost on the construction site.

Another limiting shear is under the designation WSS-Tilt-wing and Limiting scissors from Wilhelm Schlechtendahl & Sons on the market. This Limiting scissors are on the frame side in a clampable in the frame profile Frame block pivotally mounted, the limiting scissors with the Frame block is firmly connected. On the sash frame side is a guide piece in one Guide groove guided longitudinally, the limiting scissors with a bearing pivotably mounted on a pivot pin located on the guide piece connected and held by means of a locking plate. The guide piece points on the side opposite the pivot pin, i.e. the back, one of a tensioning screw that can be tensioned, axially developing tensioning arch, depending on Tension exerts a braking effect in the guide groove. One in the guide groove clampable stop limits the displacement of the guide piece and determines thus the swivel range of the window sash.

Furthermore, the present invention relates to a guide part for a limiting shear, that in a frame or turn, turn-tilt or tilt-turn sash is arranged, consisting of at least one pair of limiting scissors on one End in the guide part and the other end in a pair of scissor bearings is pivotally articulated, the guide part in a guide groove is guided longitudinally and has a braking device.

Limiting scissors are known, on the one hand, to be fixed and pivotable, on the other hand pivotable on a guide part, and this in turn in a guide groove to be arranged in a longitudinally displaceable manner. It is also known to brake the so-called Assign the guide part, which means that the guide part passes too quickly Avoid guiding groove and thus swinging out the window or door leaf. However, the adjustment of the components and in particular the limiting scissors is problematic itself, as can be seen from DE 44 07 245, the one for this special device.

Another limiting scissors are known from EP 0 538 586 a base plate attached to the frame is mounted so that it can be moved and adjusted, whereby the window sash in the installed state according to the requirements can be adjusted slightly.

As mentioned at the beginning, the large number of components involved requires one accordingly high storage and assembly costs. Manufacturing is also expensive and the stock of the components is accordingly extensive. The binding of Measured against the value of the components, resources are disproportionately high.

Burglary security must also be taken into account. The well-known limiting scissors are often only able to withstand a break-in attempt to a limited extent, because of the cramped space the securing means more or less easily accessible are not too difficult to install the limit rail and thus time consuming to design.

To fasten the frame in the masonry, the wings are on site Frame usually to separate, or at least unhook the boundary scissors to to enable a fitting installation. This requires a considerable amount Assembly workload. There is also a latent risk of injury because heavy when removing and / or installing the sash from or into the frame Crushing of the hands or fingers in particular can be caused.

Part of a pair of limiting scissors for one arranged in a frame Turn, turn-tilt or tilt-turn sash is often a brake device Guide part, which is pivotally articulated at the end of the limiting scissors and in a guide groove is longitudinally displaceable. At the other end is the boundary scissors swivel-articulated in a scissor hinge bracket.

Such a guide part is subject to a high level as a moving component Wear. On the other hand, it is essential for the proper functioning of the Limiting scissors of crucial importance. With the aforementioned known guide part, the braking effect by a bridge-like Bending section of the bottom of the slide sliding in the guide groove and pointing inwards Guide part on the one hand and by support on the boundary scissors facing Surface of the guide groove on the other hand causes. The material load is included comparatively high. A break in the bending section leads to immediate and sustainable dysfunction. The area of the The guide groove exerts great influence on the guide part. Nicks, ridges and the like scrape on the guide part and can drastically impair the braking effect.

The object of the invention is therefore to provide a pair of limiting scissors has low component expenditure, is easy to transport and simple to assemble and is safe to use.

This task is in a boundary scissors according to the preamble of Claim 1 solved in that the braking device at least one Has wedge flank functional means (expansion wedge), which together with the Guide part in an ineffective starting position cohesively with the guide part Connected, integral component forms, the functional means (expanding wedge) by means of a Actuator from the integral material connection (connecting webs) from the guide part can be separated by force and transferred into a functional position in which the Wedge flank with at least one congruent ramp surface of the guide part in Operational connection occurs for the purpose of generating a variably adjustable with the actuator Braking effect in the guide groove.

Here, the material bond is preferably embodied by so-called film hinges. Such a thing Guide part is characterized primarily by the fact that it injection molding is easily manufactured as a bulk and preferably the Braking effect on the cheeks of the guide groove. This makes the material of the Guide part largely protected from scraping edges and the like Braking effect almost constant over a long period of time. Installation as such is very simple, since no special parts of the brake in the pre-assembly Groove or the guide piece are to be introduced, but only the guide piece in the Guide groove is to be used.

According to a further feature of the invention, the actuator is used as a train effective force both the functional means (expansion wedge) from the integral material bond - in particular in the form of film hinges or the like as well as adjustable with the actuator. As a result, the Assembly by means of the actuator on the one hand separating the expanding wedge and at the same time on others the braking effect can be permanently adjusted in one operation.

According to the invention, the actuator extends essentially in the longitudinal direction, supported at one end and arranged to penetrate the guide part, whereby on the other hand, the limiting scissors are pivotally mounted.

This can be achieved by the relative orientation of the functional means on the guide part Install the actuator in a simple way.

The actuator is advantageous according to a further feature of the invention in the form of a Set screw formed which the guide part in the longitudinal direction in a the guide part penetrating hole. The set screw is above External thread with an internal thread of the functional means (expansion wedge) in unloaded Engagement, the expanding wedge with the guide part preferably over to the internal thread symmetrically arranged cohesive connecting webs is integrally connected. The set screw rests unloaded with a collar, preferably the screw head externally on the guide part, first by screwing in the set screw their covenant is in operative connection with the guide part. When screwing in further the functional means are separated from the connecting webs and the functional means (Spreader wedge) finally transferred into a functional position generating a braking effect. The guide part designed in this way is particularly easy to assemble.

It is particularly advantageous for pre-assembly if after another feature of the invention, the guide member and the boundary scissors with each other are connected to a handling unit. As a result, the handling unit in the guide groove are securely received and secured with a stop. For this purpose, the stop preferably has at least one claw which the limiting scissors attacks in the area of the mushroom head pin and so the handling unit fixed. In this way it can be avoided that the limiting scissors when Unsecured transportation is damaged as the casement and window frame often be transported separately to the building.

Another advantage is that the limiting scissors Has connecting means with which they by a latching connection with the Scissor bearing block can be connected in a receptacle assigned to it.

The latching connection of the limiting scissors from the inactive position out with the fixedly arranged scissor bearing block allows a special quick and safe installation. The period during which parts are unsecured and pose a risk of injury to a minimum. The limiting scissors in question are secured immediately after connection. The Assembly is straightforward and can also be carried out by less experienced people. Finally, no special devices are required for assembly. On Surprisingly simple, the object according to the invention solves several related tasks. In addition to the low-cost production and stockpiling also improves security as the latching connection of is hardly accessible from the outside.

In Fig. 1 is an arrangement 10 of a rotary wing 11 in the swung open state shown opening on the right or left. The rotating wings 11 are each via hinge bearings 12 connected to a frame 13.

Limiting scissors 14 are clearly visible, which at one end 15 in one Guide part 16 and at their other end 17 in a scissor bracket 18 each is pivotally mounted. The guide part 16 is longitudinally displaceable in a guide groove 19 guided. Its range of motion is in the open direction 20 of the wing 11 limited by a stop 21. With the stop 21, the opening angle - usually to 90 ° - fixed. The scissor bearing bracket 18 is in a groove 22 of the frame 13 stationary in the area of the hinge bearing 12.

As can be seen in particular from FIG. 2, the guide part 16 is in the guide groove 19 of the wing 11 when opening, and moved away from the stop 21 when closing.

The assignment of the scissor bracket 18 and the guide part 16 can also Conversely, that is, in such a way that the scissor-type bearing block 18 the rotary wing 11th and the guide part 16 is assigned to the frame 13.

Referring to Figs. 3 to 5 is subsequently that in the groove 22 of the frame 13 fixed scissor bracket 18 explained. The scissor bearing bracket 18 has a substantially symmetrical, elongated shape and is centered arranged holding member 30 in the groove 22 of the frame 13 by means of a tendon 31 ascertainable. The tendon 31 is transverse to the longitudinal axis of the scissor bracket 18 in with respect to the groove 22 at an inclination angle α inclined. The groove 22 facing side of the tendon 31 has a fixing tip 32 by a Pressure cone 33 is followed, the flank angle β largely the helix angle α corresponds. If the tendon 31 functions in the form of a grub screw, it unfolds first the fixing tip 32 has a holding effect. This is for the quick assembly of great advantage since the groove 22 as such is not unnecessarily damaged. Is the one you want Position reached, the tendon 31 occurs completely in a groove with the groove 22 in operative connection, in that the pressure cone 33 is in a wall 23 of the groove 22 creates a slight depression 34 and creates a semi-positive connection creates, as shown in FIGS. 5a and 5b.

The holding member 30 rests in the center of a recess 35 in the scissor-type bearing block 18 its distal ends each have a stepped bearing bore 36 in which a a snap connection 37 provided bearing pin 38 of a spring member 40 engages. The spring member 40 is aligned in the longitudinal direction of the scissor-type bearing block 18. In addition, the spring member 40 is at its one with respect to the scissor bracket 18 End pivotally mounted and in the axial direction by means of the snap connection 37 the bearing bore 36 fixed. At its other end, the spring member 40 is in the Retaining member 30 molded lugs 39 as a means for two-axis shackling of the spring member 40 held.

A receptacle 41 is arranged approximately centrally to the spring member 40, which essentially has a square cross section. The spring member 40 engages between the lugs 39 a, the spring member 40 crossing the receptacle 41 partially overlapping. At in the Groove 22 inserted scissor bracket 18 is the spring member 40 as such from the outside inaccessible.

In Figs. 6 to 8 is the interaction of limiting scissors 14 and Scissor bracket 18 shown. With the limiting scissors 14 is at its other end 17 a mushroom head pin 45, which is a connecting means to the Scissor bracket 18 forms. The mushroom head pin 45 has a run-on slope 46 which is followed by an undercut 47. Is the limiting scissors 14 with the Scissor bracket 18 after installing sash 11 and frame 13 in the To connect masonry, the mushroom pin 45 is pressed into the receptacle 41, wherein the spring member 40 from the run-up slope 46 in the bearing bore 36 of the Scissor bracket pivoting 18 deflects around finally in the undercut 47 to engage in a latching manner, whereby an axial fixation can be pivoted at the same time stored connection 50 can be effected.

The spring member 40 has spacing means 42 arranged on both sides of the receptacle 41 Form of pin-shaped, rounded approaches, which change when the Support mushroom pin 45 in the receptacle 41 on the inner wall 23 of the groove 22 and avoid deflection in the axial direction of the spring member 40.

The limiting scissors 14 is thus via a connecting means with which they are made from a ineffective position by means of a latching connection 50 with the Scissor-type bearing block 18 in the receptacle 41 assigned to it connectable according to the installation needs. Several can do this Spring members 40 are assigned to the limiting scissors 14 in the direction of loading lie, which cause the latching connection 50 and the limiting scissors 14th to back up. Furthermore, the spring member 40 is hollow in the region of the receptacle 41 curved, arranged parallel to the bearing pin 38 rounding 43 which allows the spring member 40 to engage deeper in the undercut 47 and a larger one Locking resilience enabled. As shown in Figs. 3, 6, 7 and 9 can be seen hollow curved curve 43 symmetrically attached to the spring member 40 so that it can be used both for the left and for the right spring member 40.

At the pivotable end, that is, the bearing pin 38 of the spring member 40, this has a centrally arranged adjusting means in the form of a hexagon socket 44 or the like; see. Fig. 3, 6, 7, 9 and 10a. This is the latching connection 50 of Limiting scissors 14 and scissor bearing block 18 releasable by a corresponding Tool 46 is used and the spring member 40 from the undercut 47 is pivoted, whereby the mushroom head pin 45 is detachable from the receptacle 41; see. Fig. 10b and 10c. By special design of the actuating means 45 and the associated one Tool 48 can achieve a high level of resistance to accidental loosening become.

At the end 15 of the limiting scissors opposite the scissor-type bearing block 18 14 - as indicated in Fig. 1 - the guide member 16 is pivotally mounted and in a guide groove 19 guided longitudinally. The guide part 16 also has a Brake device 60 as shown in FIG. 1.

The functionally not yet set state, ie an ineffective position 62 of the Guide part 16 is shown in more detail in FIG. 11. The guide member 16 is there with the Brake device 60 shown, wherein part of the brake device 60 in the form of a Expansion wedge 61, which is in the inactive position 62 cohesively via two film hinges 63 is connected to the guide part 16. The expanding wedge 61 is symmetrical arranged wedge flanks 64 and an internal thread 65 arranged between them. The guide member 16 is on the, the swivel mounting of the Limiting scissors 14 opposite one side, essentially in Longitudinally extending actuator in the form of an adjusting screw 67 with a External thread 68 in a bore 69 passing through the guide part 16 penetrated, which engages in the internal thread 65 of the expansion wedge 61 unloaded. As in 11 can be clearly seen, the adjusting screw 67 has a bore 69 overlapping screw head 70 with a collar 75, which by means of a tool 71 with appropriate training is movable.

Within the guide part 16 are congruent to the wedge flanks 64 of the expanding wedge 61 trained ramp surfaces 72 spaced, each of which bridge members 76 are assigned.

If, as indicated in FIG. 11, the adjusting screw 67 is made using the tool 71 screwed in, the screw head 70 first arrives with its collar 75 with the Outside 73 of the guide part 16 in contact. When turning the The screw 67 becomes the integral connections, i.e. the expansion wedge 61 with the guide part 16 connecting film hinges 63 by exceeding the Cut tensile strength at predetermined breaking points 91. In another script the Spreading wedge 61 in its functional position 74, in which the wedge flanks 64 with the ramp surfaces 72 of the guide part 16 come into operative connection. The desired braking effect is then set by means of the adjusting screw 67. Since the guide member 16 in the guide groove 19 runs with little play, only small stretches occur in the area of the ramp surfaces 72 which, on the one hand, is characterized by the elastic material properties of the a polymer existing guide part 16 can be compensated per se. On the other hand there is a further comfortable by appropriate training of the bridge members 76 Influencing the structural mechanical behavior of the guide part 16.

The actuator, embodied by the adjusting screw 67, effectively separates by means of a train force acting on the integral existing through the film hinges 63 Material connection at the predetermined breaking points 91, and also causes the variable by train Setting the braking effect.

As the fig. 11 and 12 show the guide part 16 and the limiting scissors 14 connected to one another to form a handling unit 80.

The handling unit 80 is with the wedge 61 in the inactive position 62 shown, wherein the tool 71 is set for adjustment. The clamping means 67 is not yet under power. The predetermined breaking points 91 are still intact.

In contrast, in FIG. 12 the handling unit 80 is effective in terms of braking technology Functional layer 74 shown. The predetermined breaking points 91 are due to the tensioning means 67 generated tractive force severed. The wedge flanks 64 of the expansion wedge 61 are with the Ramp surfaces 72 of the guide piece 16 in operative connection.

As can be seen from FIG. 13, the handling unit 80 is in the guide groove 19 of the Wing 11 recordable, with the loose end provided with the mushroom pin 45 with the stop 21 is secured as a transport lock. For this purpose, the stop 21 instructs a claw 82 on each end, which the limiting scissors 14 in the mushroom pin 45 and the handling unit 80 or the limiting scissors 14 securely fixed under elastic tension of the limiting scissors 14.

The stop 21 has a locking screw for fastening in the guide groove 19 83 on. 14 is an injection molding process, preferably made of a polymer producible semi-finished product 90 for a guide part 16 with two inside Connecting webs 63 in the integral material connection connected functional means in the form of Spreading wedge 61 shown for the braking device 60. Are clear on the Crosspieces 63 the predetermined breaking points 91 for later separation by means of tensile force to recognize. The functional means 61, embodied by the expanding wedge 61, has two Wedge flanks 64, which are formed congruently in the interior of the guide part 16 Ramp areas 72 are assigned.

The guide part 16, which is essentially symmetrical to the longitudinal axis, has on its one end of a transverse bore 92, which is used to later accommodate the limiting scissors 14 or the like. And at its other end a longitudinal bore 69. Aligned to the Longitudinal bore 69 is in the expanding wedge 61 embodying the functional means Internal thread 65 arranged for later receiving the actuator 67 with which the Spreading wedge 61 from the guide member 16 then by separating the connecting webs detachable and adjustable in the desired braking effect.
