Description

The present invention relates to a limiting scissors for one in one Cover frame arranged turn, turn-tilt or tilt-turn wing, consisting at least from a pair of limiting scissors, which at one end in one Guide part and at its other end in a stationary The scissor-type bearing block is pivotally articulated, the guide part is guided in a longitudinally displaceable groove and also has a guide part a braking device together with a handling unit and a semi-finished product such guide part.

Limiting scissors for a rotating, Tilt and turn blades are known as such. They serve the Limitation of the turning or tilting range, i.e. generally the swivel movement of the wing in question, usually at 90 °.

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

The known limiting scissors has bearing eyes at their ends, which are each pivotally mounted on a pivot pin of the scissor bearing. On first hinge pin is part of a frame side and a second Hinge pin part of the wing-side scissor stay. The position of the scissor stay are set up using a template and then for the purpose of Pre-anchored by hammering into the frame, one on the Underside of the cutting edge attached cutting edge in the wing or Frame cuts in. Then the anchorage takes place Scissor stay using screws to be screwed into the frame or window frame.

The known folding scissors is made in two parts, the two telescopic parts each have a curved groove, each in a retaining pin slidably slides. The curve groove also has notches in which the Engage holding pins as the curve groove runs through and a braking effect achieve.

In the known folding shears, on the one hand, the assembly is cumbersome and time consuming and on the other hand, by turning the scissor bearings into Window frames and window frames slightly damaged. The local Damage can lead to unnoticed erosion due to climatic influences of the frame. The erosion can undetect the strength of the Impair the screw connection in such a way that it can come loose suddenly. In addition, complex security measures are required for transport and pay special attention to the small parts, because 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 in the frame profile in the frame frame clampable frame block pivotally mounted, the limits tongue scissors is firmly connected to the frame block. On the casement side is a Guide piece in a guide groove guided longitudinally, the  Limiting scissors with a bearing on one on the guide piece located pivot pin pivotally connected and by means of a Locking plate is held. The guide piece points to the Trunnion opposite side, i.e. the back, one of a Clamping screw can be clamped on an axially developing clamping arch, depending on the Tension exerts a braking effect in the guide groove. One in the guide groove clampable stop limits the displacement of the guide piece and thus determines the swivel range of the window sash.

Furthermore, the present invention relates to a guide part for a Limiting scissors that in a frame or turn, tilt or turn Tilt-and-turn sash is arranged, consisting of at least one limitation shear the one end in the guide part and the other end in a scissor-type bearing block is pivotally mounted, the Guide part is guided in a longitudinally displaceable groove and one Has braking device.

It is known that the scissors on the one hand can be pivoted and fixed on the other hand pivotable on a guide part and this in turn in one To arrange the guide groove in a longitudinally displaceable manner. It is also known. Brakes to assign the guide part, the hasty passing of the Guide part of the guide groove and thus pivoting the window or Avoid the door wing. However, the adjustment of the components and is problematic in particular the limiting scissors themselves, as is the case with DE 44 07 245 can be seen, which provides a special device for this.

Another limiting scissors have become known from EP 0 538 586, which can be moved and adjusted on a base plate attached to the frame is stored, whereby the window sash in the installed state Can be adjusted slightly according to requirements.

As mentioned at the beginning, the large number of components involved require one correspondingly high expenditure in warehousing and assembly. That too is  It is expensive to manufacture and consequently the components must be stored accordingly extensive. The commitment of resources is measured by the value of the components disproportionately high.

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

To fasten the frame in the masonry are the on site Sash from the frame usually to separate, or at least the limits Unclip tongue scissors to enable a fitting installation. This requires a considerable amount of work during assembly. There is also latent Significant risk of injury because the wing is removed and / or installed severe crushing, especially of the hands, in or into the frame or fingers can be caused.

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 limiting scissors Verbin Has means with which it by a latching connection with the Scissor bearing block can be connected in a receptacle assigned to it.

The latching connection of the boundary scissors from the ineffective Positioning out with the stationary scissor bracket allows one Particularly quick and easy to handle assembly. The period during the parts of which are unsecured and pose a risk of injury is open limited to a minimum. Immediately after connecting is the one in question Limiting scissors secured. The assembly is uncomplicated and also from  less experienced people feasible. After all, there are none for assembly special devices required. The solves in a surprisingly simple way Object according to the invention several, related tasks.

In particular, in addition to the cost-effective production and stocking, the Security improved because the locking connection is hardly accessible from the outside is.

A feature of the invention is advantageously the connecting means from one Mushroom-headed cone formed with the limiting scissors at one end is firmly connected, at its other end a run-up slope and in the area the run-up bevel has an undercut, the mushroom pin in the receptacle with the undercut axially lockable and in the Recording is pivotally mounted. This is a particularly simple one Production with high functional safety.

It is advantageous according to a further feature of the invention that the recording at least one spring element is assigned that the latching connection automatically causes, whereby the limiting scissors according to the Requirements of different sizes and weights can be easily adapted and no additional devices and the like are required during installation.

According to the invention, the spring member is on his one end pivotable and tied with respect to the axial degree of freedom and is tied up at its other end with respect to two degrees of freedom, the receptacle for the mushroom head pin is approximately in the middle of the spring member is arranged. This makes assembly considerably easier, while at the same time secure connection of mushroom head peg and intake is achieved.

According to a further feature of the invention, the spring member has on its pivotable end at least one adjusting means, preferably in the form of an interior hexagon or the like. This is also the assembly or disassembly relieved, because the automatically locking connection of limiting scissors and Scissor hinge bracket can be released with the appropriate tool.  

The spring member advantageously has a bearing journal which is connected to a Snap connection is provided, the bearing journal in a bearing bore the scissor bracket is pivotally mounted and the snap connection Bearing pin fixed in an axial direction, which is the manufacture as well as the Assembly further simplified.

Preferably, the spring member has at least one spacer, which is when latching insertion of the connecting means against a wall of the Groove supports. This ensures without additional funds that when later connecting the mushroom head pin to the scissor bearing block locking connection is established safely.

According to a further feature of the invention, the spring member is in the groove in used state of the scissor bracket inaccessible from the outside houses, which makes manipulation difficult.

The spring member advantageously has one, in particular in the region of the receptacle square cross-section. This makes a good spring technology Material utilization causes. Optionally, the spring element also points in the area the receptacle parallel to the bearing pin at least one hollow Rounding up the locking connection by expanding the The effective area is reinforced.

The scissor-type bearing block essentially has a further feature of Invention an elongated shape and is preferably in with a holding member the groove of the frame can be determined by means of a tendon.

The scissor bearing block advantageously has a symmetrical shape, with the Holding member is arranged centrally. This further relieves the stock because the scissor bracket is suitable for both left and right hinges.  

The holding member also has means for two-axis shackling of the spring member on, which are easy to form, in particular in the form of lugs on the holding member.

According to a further feature of the invention, the spring member is in the longitudinal direction of the scissor-type bearing pedestal, where there is a preference shows that the spring property not only affects the material, but also according to the length that can be freely selected in this case. It follows get a better elastic property.

It is particularly advantageous that the spring member in the loading direction Limiting scissors are located and the mushroom pin in the Scissor hinge bracket is added. This will make an additional one sustainable Hold the pressure scissors on the locking Connection achieved, whereby the pressure is distributed over a larger attack surface can and thus reduces a compressive stress.

Part of a pair of limiting scissors for one in a frame ordered turn, turn-tilt or tilt-turn sash is often a one Guide device having a braking device, which at the end of the limit tongue scissors pivotally articulated and longitudinally in a guide groove is guided. At the other end, the limiting scissors are swiveled 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. At the beginning mentioned, known guide part, the braking effect by a bridge-like bending section of the sliding in the guide groove, inward pointing bottom of the guide part on the one hand and by supporting the Limiting scissors facing surfaces of the guide groove on the other hand causes. The material load is comparatively high. A break of the Bending section leads to immediate and lasting malfunction. The the Limiting scissors facing surface of the guide groove exerts on the  Leadership part of great influence. Notches, ridges and the like scrape on the Guide part and can drastically affect the braking effect.

Another object of the invention is therefore a guide part in particular for the specified scissors to create that at little effort in terms of production, storage and installation Has the highest level of functional reliability.

This object is achieved in that the braking device has a functional means (spreading wedge) having at least one wedge flank, that together with the guide part in an ineffective starting position integrally connected to the guide member forms an integral member, wherein the functional means (expanding wedge) by means of an actuator from the integral Material connection (connecting webs) from the guide part by means of force separable (predetermined breaking point) and can be converted into a functional position in which the Wedge flank with at least one congruent ramp surface of the guide part in Active connection occurs in order to generate a variable with the actuator adjustable braking effect in the guide groove. Here is the material connection preferably embodied by so-called film hinges. Such a guide part is particularly characterized in that it is injection molded as Bulk is easy to manufacture and preferably the braking effect on the Cheeks of the guide groove. As a result, the material of the guide part largely protected from scraping edges and the like and the braking effect Can be kept almost constant over a long period of time. The installation as such is very easy, since no special parts of the brake fit into the groove during pre-assembly or to introduce the guide piece, 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 (spreading wedge) the integral material bond - in particular in the form of film hinges or the like executed - releasable and adjustable with the actuator, the braking effect. As a result, on the one hand, the expansion wedge is used for assembly by means of the actuator  Separating and at the same time the braking effect in one operation permanently adjustable.

According to the invention the actuator is substantially in the longitudinal direction extending, supporting at one end and penetrating the guide part arranged, the limiting scissors pivotally mounted on the other is recorded.

The relative orientation of the functional means on the guide part allows assemble the actuator in a simple way.

According to a further feature of the invention, the actuator is advantageously in shape formed a set screw that the guide part in the longitudinal direction in a Penetrating through the guide part. Here is the set screw via an external thread with an internal thread of the functional means (expansion wedge) in unloaded engagement, with the expanding wedge preferred with the guide part wise cohesive Ver arranged symmetrically to the internal thread connecting webs is integrally connected. The set screw rests with no load Collar, preferably the screw head on the outside of the guide part, with First screw in the set screw with its collar with the guide part enters into active connection. When screwing in further, the functional agent is removed from the Separating webs and the functional means (spreading wedge) finally transferred to 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 according to the invention, the guide part and the limiting scissors are connected to one another to form a handling unit. This allows the Handling unit can be safely accommodated in the guide groove and with secured against a stop. The stop preferably has this at least one claw, which the limiting scissors in the area of Attacks the mushroom head pin and fixes the handling unit. In this way can be avoided that the limiting scissors during unsecured transport  is damaged because the sash and frame often separate from the building be transported.

A semi-finished product for an in is technically advantageous according to the invention a guide groove of a frame or a turn, turn-tilt or Tilt-and-turn wing longitudinally displaceable guide part for connection with a limiting scissors that at one end in the guide part and at the other end is pivotally articulated in a scissor hinge bracket, wherein the guide member has functional means of a braking device when the functional means of the braking device by means of at least one Connecting web to the guide part in an integral material connection is assigned, the connecting web being at least one predetermined breaking point has for later separation and transfer of the functional means in a functional position generating a braking effect. Such a semi-finished product allows a significant reduction in the manufacturing process, in particular when it is manufactured as an injection molding part.

It is preferably made of a polymer that easily has the properties in the the desired way of influencing additives can be added.

The guide part advantageously has a shape symmetrical to the longitudinal axis. The functional means according to a further feature of the Invention essentially as an expanding wedge with at least one wedge flank and a longitudinally oriented internal thread. The guide part has a largely aligned with the internal thread, the guide part in Longitudinal penetrating hole on. The guide part itself points at least one, in particular internal, congruent to the wedge flank Ramp area on.

The present invention thus combines the requirement according to the task easier manufacturing and warehousing with simple and inexpensive On-site installation. In addition, the inventive design of the Guide part the use of guide grooves with a low profile as well  the use of so-called Euro slots (10 to 14 mm) and reduces the effort Components.

In particular, the force application of the scissors to the brake remains in the essentially constant, so that a uniform over a long period Braking effect can be achieved.

The invention is based on a more or less schematic illustrated embodiment explained in more detail. The same components are included each designated the same reference number.

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

A pair of limiting scissors 14 can be clearly seen, each of which is mounted at its one end 15 in a guide part 16 and at its other end 17 in a scissor-type bearing block 18 in a pivotable manner. The guide part 16 is guided in a longitudinally displaceable manner in a guide groove 19 . Its range of motion is limited in the open direction 20 of the wing 11 by a stop 21 . With the stop 21 , the opening angle - usually 90 ° - is determined. The scissor-type bearing block 18 is arranged in a fixed manner in a groove 22 of the frame 13 in the area of the hinge bearing 12 .

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

The assignment of the scissor-type bearing block 18 and the guide part 16 can also be carried out in reverse, that is, such that the scissor-type bearing block 18 is assigned to the rotating wing 11 and the guide part 16 to the frame 13 .

Referring to FIGS. 3 to 5 fixed in the groove 22 of the frame 13 arranged scissor bearing block 18 is explained below. The scissor-type bearing block 18 has an essentially symmetrical, elongated shape and can be fixed by means of a tensioning element 31 with a centrally arranged holding element 30 in the groove 22 of the frame 13 . The tendon 31 is arranged transversely to the longitudinal axis of the scissor bearing bracket 18 with respect to the groove 22 at an inclination angle α. The side of the tendon 31 facing the groove 22 has a fixing tip 32 which is followed by a pressure cone 33 , the flank angle β of which largely corresponds to the helix angle α. If the tendon 31 takes the form of a grub screw, the fixing tip 32 first has a holding effect. This is of great advantage for rapid assembly, since the groove 22 as such is not unnecessarily damaged. Once the desired position has been reached, in a second step the tensioning member 31 fully interacts with the groove 22 by the pressure cone 33 creating a slight depression 34 in a wall 23 of the groove 22 and thus creating a semi-positive connection, as shown in FIGS. 5a and 5b.

The holding member 30 rests centrally in a recess 35 of the scissor-type bearing block 18 , which has a stepped bearing bore 36 at its distal ends, in which a bearing pin 38 of a spring member 40 , which is provided with a snap connection 37 , 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 pivotally mounted at one end with respect to the scissor bearing bracket 18 and fixed in the axial direction in the bearing bore 36 by means of the snap connection 37 . At its other end, the spring member 40 is held in lugs 39 formed on the holding member 30 as a means for biaxially capturing the spring member 40 .

A receptacle 41 is arranged approximately in the middle of the spring member 40 , which essentially has a square cross section. The spring member 40 engages between the lugs 39 , the spring member 40 crossing the receptacle 41 partially overlapping. When the scissor bearing bracket 18 is inserted into the groove 22 , the spring member 40 is housed as such inaccessible from the outside.

In Figs. 6 to 8 the cooperation of limit shears 14 and scissor bearing block 18 is shown. With the limiting scissors 14 a mushroom head pin 45 is firmly connected at its other end 17 , which forms a connecting means to the scissor-type bearing block 18 . The mushroom head pin 45 has a run-on slope 46 , which is followed by an undercut 47 . If the limiting scissors 14 are to be connected to the scissor bearing bracket 18 after the installation of sash 11 and frame 13 in the masonry, the mushroom head pin 45 is pressed into the receptacle 41 , the spring member 40 being pivotally deflected by the run-up bevel 46 in the bearing bore 36 of the scissor bearing bracket 18 to finally engage in the undercut 47 in a latching manner, as a result of which an axial fixation can be effected while the connection 50 is pivotably mounted.

The spring member 40 has spacing means 42 arranged on both sides of the receptacle 41 in the form of pin-shaped, rounded lugs, which are supported on the inner wall 23 of the groove 22 when the mushroom head pin 45 is inserted into the receptacle 41 and prevent evasion in the axial direction of the spring member 40 .

The limiting scissors 14 can thus be connected in a functional manner according to the assembly requirements by means of a connecting means with which they can be connected from an inactive position by means of a latching connection 50 to the scissor-type bearing block 18 in the receptacle 41 assigned in this. For this purpose, a plurality of spring members 40 can also be assigned, which lie in the loading direction of the limiting scissors 14 , which cause the latching connection 50 and secure the limiting scissors 14 . Furthermore, the spring member 40 is provided in the region of the receptacle 41 with a hollow arch 43 , which is arranged parallel to the bearing journal 38 and which allows the spring member 40 to engage deeper in the undercut 47 and enables a greater latching capacity. As can be seen from FIGS. 3, 6, 7 and 9, the hollow curved rounding 43 is 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 to say the bearing journal 38 of the spring element 40 , the latter 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. Hereby verrastende compound 50 of limiting shears 14 and scissor bearing block 18 is detachably by a ent speaking tool 46 is inserted and the spring member 40 is pivoted from the rear Tailoring 47, whereby the mushroom-head pin 45 is detachable from the receptacle 41; see. Fig. 10b and 10c. Through a special design of the adjusting means 45 and the associated tool 48 , a high degree of resistance against unintentional loosening can be achieved.

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

The functionally not yet set state, that is to say an ineffective position 62 of the guide part 16, is shown in more detail in FIG. 11. The guide part 16 is shown there with the braking device 60 , a part of the braking device 60 in the form of an expanding wedge 61 , which in the inactive position 62 is integrally connected to the guide part 16 via two film hinges 63 . The expanding wedge 61 has symmetrically arranged wedge flanks 64 and an internal thread 65 arranged between them. The guide part 16 is penetrated on the side opposite the pivotably articulated mounting of the limiting scissors 14 by a substantially longitudinally extending actuator in the form of an adjusting screw 67 with an external thread 68 in a bore 69 penetrating the guide part 16 , which into the internal thread 65 of the expanding wedge 61 engages unloaded. As can be clearly seen in FIG. 11, the adjusting screw 67 has a screw head 70 covering the bore 69 with a collar 75 which can be moved by means of a tool 71 with the appropriate design.

Ramp surfaces 72 , which are congruent to the wedge flanks 64 of the expanding wedge 61, are arranged within the guide part 16 , with bridge members 76 being assigned to each of them.

If, as indicated in FIG. 11, the set screw 67 is screwed in by means of the tool 71 , the screw head 70 with its collar 75 first comes into contact with the outside 73 of the guide part 16 . When the adjusting screw 67 is screwed in further, the integral connections, that is to say the film hinges 63 connecting the expansion wedge 61 to the guide part 16 , are severed at predetermined breaking points 91 by exceeding the tensile strength. In a further step, the expanding wedge 61 reaches its functional position 74 , in which the wedge flanks 64 come into operative connection with the ramp surfaces 72 of the guide part 16 . The desired braking effect is then set using the adjusting screw 67 . Since the guide part 16 runs in the guide groove 19 with little play, only small expansions occur in the area of the ramp surfaces 72 , which are compensated for by the elastic material properties of the guide part 16, which is generally made of a polymer. On the other hand, by appropriately designing the bridge members 76, there is a further comfortable influence on the structural mechanical behavior of the guide part 16 .

The actuator, embodied by the adjusting screw 67 , accordingly separates the force acting through the action of a force acting on the integral material connection formed by the film hinges 63 at the predetermined breaking points 91 , and likewise effects the variable adjustment of the braking effect by tension.

As shown in FIGS. 11 and 12 show, the guide member 16 and the scissor-type restricting 14 are interconnected to form a handling unit 80. The handling unit 80 is shown with the wedge 61 in the inactive position 62 , the tool 71 being set for adjustment. The tensioning means 67 has not yet been subjected to force. The predetermined breaking points 91 are still intact.

In contrast, FIG. 12 shows the handling unit 80 in the functional position 74 that is effective in terms of braking technology. The predetermined breaking points 91 are severed due to the tensile force generated by the tensioning means 67 . The wedge flanks 64 of the expansion wedge 61 are operatively connected to the ramp surfaces 72 of the guide piece 16 .

As can be seen from FIG. 13, the handling unit 80 can be accommodated in the guide groove 19 of the wing 11 , the loose end provided with the mushroom head pin 45 being secured with the stop 21 as a transport lock. For this purpose, the stop 21 has a claw 82 at each end, which engages around the limiting scissors 14 in the region of the mushroom-head pin 45 and securely fixes the handling unit 80 or the limiting scissors 14 under elastic tensioning of the limiting scissors 14 .

The stop 21 has a locking screw 83 for fastening in the guide groove 19 . In Fig. 14 a, preferably producible from a polymer by injection molding semi-finished product 90 is shown for a guide member 16 with connected in the interior of two connecting webs 63 in an integral material connection function means in the form of the expanding wedge 61 for the braking device 60. The predetermined breaking points 91 for later separation by means of tensile force can be clearly seen on the connecting webs 63 . The functional means 61 , embodied by the expanding wedge 61 , has two wedge flanks 64 , which are assigned congruent ramp surfaces 72 in the interior of the guide part 16 .

The substantially symmetrical to the longitudinal axis guide member 16 has at one end a transverse bore 92 , the later receiving the limiting scissors 14 or the like. And at its other end a longitudinal bore 69 . The internal thread 65 is arranged in alignment with the longitudinal bore 69 in the expansion wedge 61 embodying the functional means, for later accommodation of the actuator 67 , with which the expansion wedge 61 can then be separated from the guide part 16 by separating the connecting webs and can be adjusted in the desired braking effect.
