Description

TROLLEY ARRANGEMENT FOR LIFTING SLIDING DOORS OR WINDOWS

The invention relates to a carriage arrangement for hard-to-lift and movable wings of a window or a door according to the preamble of claim 1.

It is already known from the prior art, for example from EP 1298272 A2, to design fittings for lifting-sliding doors or windows, each with at least two carriages. To open and close the door or window sash of such a door or such a window, it is necessary to raise or lower this wing. For this purpose, the carriage lifting means which between a carriage element of the relevant carriage, which carriage element with rails on the frame

having cooperating rollers, and act in addition to a bearing which is fixed to the wing, and which cause in a displacement of the carriage elements relative to their bearings in the carriage longitudinal direction corresponding to a lifting curve, the raising and lowering of the wing.

The carriage elements of the various carriages of a fitting are connected to one another via a coupling rod, so that all carriage elements for raising and lowering the wing are moved in the same direction.

Especially with multiple glazing, as they are customary today and also prescribed because of the heat protection regulations, have large area

Wing a considerable weight, which must be transferred from the carriage or its roles on the track.

For reasons of quietest possible operation and to avoid wear on the track these rollers are usually made of plastic, often made of glass fiber reinforced plastic (eg polyamide). With increasing sash weight such rollers come very quickly to the limit of their capacity. For this reason, fittings such as those known from the prior art of EP 1298272 A2, according to the weight of the wing with more than two carriages trained. For this purpose, the carriages are arranged one behind the other and coupled with connecting rods.

Although the aforementioned embodiment carries the higher sash weight, but they require a large amount of space, require a high assembly cost and are very expensive. In addition, the effect is limited by the number of other roles, as a result of the long series of consecutive with

Connecting rods connected carriages and by dimensional inaccuracies of the door or the window, and by the running rail and the carriage itself not all roles can transfer the heavy weight on the track, since the rigid bearing of the carriage can not compensate for the dimensional inaccuracies and so the contact with the track is missing , which continues to weigh on the roles and can shorten the life. The invention is therefore based on the object to show a carriage assembly, which is also suitable for increased sash weights with high reliability and are covered with the least possible component complexity with simple installation all possible variants of a liftable and movable wing.

The solution of this problem is achieved by the means of the characterizing part of claim 1 and claim 13.

The carriage arrangement according to the invention can be mounted in a simple manner to the correspondingly required position and can be due to the low component cost and very space-saving continue, as in the conventional manner completely hidden at the lower horizontal wing spar attach. In this case, the carriage assembly and the carriage itself forms an integral unit that adapts to the circumstances, in particular the fitting groove of the movable wing. Another advantage of the illustrated and described embodiment of the carriage assembly is also that the carriages each have two pairs of rollers with two roles, so that increases the number of roles from the conventional number on the wing of a total of four roles on eight roles. Furthermore, the pendulum bearing of the pairs of rollers over the rollers compensates for any dimensional inaccuracies, so that the weight of the wing on the frame evenly distributed on all roles individually and transmits to the arranged on the frame rail, which is It also has an advantageous positive effect on the runnability. By maintaining the installation position of the front carriage and the rear

Carriage with support of the wing essentially on the two end sides of this wing, also by the multiple glazing over the guidelines prescribed blockage is worn.

Further advantageous embodiments will become apparent from the claims 2 to 13.

An expedient, because simple and inexpensive production of

Carriage arrangement is ensured when the pairs of rollers are configured symmetrically and identically formed in the carriage can be mounted. By using the same components of the pair of rollers in the front carriage and rear carriage, the assembly is also easier as a test

different variants deleted.

A simple assembly and a zweckerfüllende complete load bearing of the wing on the carriage is achieved in that arranged on a central axis of the pair of rollers pendulum bearing by a roller carrier arranged on the bore and a rotatable with the bore and on

Roller bearing element attached pin is formed. With the arrangement of the fulcrum on the central axis of the roller carrier inaccuracies between the rollers and the track can be compensated automatically.

A further preferred embodiment provides that the pin has a shoulder, which spaced the roller bearing elements transversely to a carriage longitudinal axis of the carriage in a predetermined position, so that the

Roller pairs are freely movably guided between the roller bearing elements and the roller bearing elements are freely movably positioned in the fitting groove. The arranged on the pin paragraph determines depending on its width, the smooth rotational movement of the pairs of rollers and the free movement of the carriage within the fitting, bringing a reliable functionality of

Carriage assembly is achieved.

In order to achieve a particularly good running property and low wear with high stability of the pairs of rollers, the shoulder is designed as a sliding bearing element, and preferably made of a plastic material, wherein the paragraph forms a virtually play-free unit in connection with the pin. According to a further preferred embodiment of the present invention, the roller carrier is made of a material produced by injection molding, a stamped and bent part or an extruded profile. All variants shown are suitable for the absorption of high weights and can

manufacturing technology are simple and inexpensive to manufacture. Furthermore, the roller carrier forms a simple and stable support for the rollers.

In order to provide a particularly compact structure, the front carriage, which is the wing side with the actuating linkage and the actuator closest, preferably integrally formed with the corner deflection, wherein the housing arranged in a longitudinal extent of the fitting groove and the

Has fitting groove directed flat portion which extends with transition into the vertical fitting groove and the deflecting components of the corner drive movably receives by projecting webs. Due to the integral structure of the

Trolley with the corner drive, reduce the assembly work of the fitting. In addition, a stop edge for the carriage in the horizontal direction has been created by the corner deflection, so that so that the

Reduce attack times. In addition, find the items of the corner drive from existing components of the operating fitting your use, which affects the manufacturing costs and also the installation costs in an advantageous manner, since the same assembly tools can be used.

A further preferred embodiment provides that the flat portion in the region of a pair of rollers, which is closest to the corner deflection, a

Section has, in which engage the rollers. Through the cut the carriage can be executed in integral construction with the corner drive without changing the height of the component, which would have required a change in the depth of the fitting groove.

In order to obtain as much support surface for the carriage at the bottom of the fitting for receiving holes for attachment via fasteners and for support of the wing by the carriage, which is arranged at the top of the carriage flat portion of the housing and a flat portion of the housing in cross-section the dimensions trained the fitting person. At the same time, the flat portion of the front carriage and the flat portion of the rear carriage the total width of the carriage, with all other components of the Carriage, however, and are thus narrower compared to the width of the fitting groove to avoid unnecessary noise when moving and to ensure smooth operation of the carriage. A secure operation of the wing element, in particular when lifting and when moving horizontally relative to the frame is also achieved in that the front carriage is arranged at the open end facing the rear carriage and the rear carriage at the open end to the front carriage a coupling element, which frictionally receives the connecting rod. By maintaining the same position of the front carriage and the rear carriage and connection through the connecting rod, the wing can be raised and lowered evenly controlled by the actuator, with the male wing weight distributed to the two carriages. Since the fitting groove is an essential criterion of the outer design of the wing with respect to the dimensions in depth and width, and a tendency can be seen in the reduction of the material of the wing and the frame of the window or door and in the increase of the glass surface According to a further advantageous embodiment of the present invention, the housing of the front and rear carriage on the side directed to the Beschaltungsut a fixing pin, which engages in each case a bore of the lower horizontal wing spar at the upper bottom of the fitting groove and the two carriages

Fixing screws find the insert in the wing.

A further preferred embodiment provides that the fixing pin is preferably a dowel pin. The tension pin fits into the on the wing of the lower horizontal

Wing spar arranged at the bottom of the fitting groove holes form fit.

By choosing the tension pin the carriages are held almost free of play in a prefixed position and kept in a secure manner in the horizontal direction or the direction of movement of the wing. Due to the design, higher

Sash weights are added and savings in the number of others

Fasteners are made and / or the fasteners are reduced in size and length. In addition, the invention relates to a method for assembling a carriage assembly for hard-to-raise and moving wings of a window or door, consisting of a front carriage, via a coupling element with one end of a connecting rod and with the coupling element of a rear carriage of the other end of the connecting rod frictionally to support the wing a pair of carriages educate is to connect. For this purpose, the front and the rear carriage each have a housing, wherein on each side of the housing to the carriage longitudinal direction a pair of rollers is arranged.

The pair of rollers consists of a roller carrier and at this at a distance in each case from the central axis of the roller carrier, two pendulum mounted rollers. With assembly of the carriage assembly in the wing, is to position the position on the respective housings of the carriage on the

Embodiments find their application.

For simplicity, only the use of the

Carriage assembly described in a liftable but preferably movable wing 2 of a window or a door and shown in Fig. 1, although the invention is also suitable for a lift-slide-tilt windows or doors. In a fixed frame 35, a wing 2 in the direction of arrow 36 can be raised and then slidably disposed in the direction of arrow 37, wherein the arrow 37 symbolizes the direction of opening. The lifting takes place in a known manner by means of a handle formed as an actuating member 6, which is pivoted here in the direction of the arrow 38 of the rotational movement. The rotational movement is transmitted to a drive rod 5 in particular via an actuating linkage 4 of known type. The mounting rod 4 is also in a known manner via a lower

Eckumlenkung 7 coupled with a front carriage 1. A connecting rod 10 leads to a second or rear carriage 1 ^' . If about one

Rotary movement 38 of the actuator 6, the drive rod 5 in the direction of the arrow 39 of the sliding direction is thus shifted upwards, this causes a

Displacement of the carriage 1, 1 ^' relative to the lower end of the wing also a sliding direction of the arrow 40, wherein the wing 2 is raised simultaneously. Between two roller bearing elements 17, 18 of the carriage 1 and 19, 20 of the carriage 1 ^' , a lifting roller 41 is used, which together with a lifting cam 42 of the movable wing 2 forms a lifting device 12. The lifting cam 42 simultaneously represents the upper limit of a guide slot 43 of a lower horizontal spar of the movable wing 2 anmontierten housing 1 1, 1 1 ^' in Fig. The curvature of the guide slot 43 and the course of the lift cam 42 is selected so that the movable wing 2 - starting from the closed position - is raised during the rotational movement 38 of the actuating member 6. As a result, the fitting runs, which position at the same time the displacement position of movable wing 2, on the lifting roller 41 adjacent part of the lifting cam 42 is relatively flat to the horizontal or to the longitudinal axis of the running rail 3 in a not shown opposite to the arrow 40 movable opening position. If the wing 2 from the open position in the direction of arrow 40 in the

Shut the locked position and then the actuator 6 opposite to the arrow 38 as shown in Fig. 1 shown closure position, automatically lowers the wing 2 and not shown on the vertical wing spar arranged locking members engage in the arranged on the vertical Rahmenholm frame closure parts. In the closed position of the wing 2 is sealed at its lower end, for example via two in the lower cross member not shown in the figures recessed sealing strips against the fixed frame 35, said sealing strips are often pressed against horizontal leg of a running rail 3 sealing. Other upper sealing strips also not shown are pressed against the lowered wing 2 at the associated profile end of an upper guide rail. Corresponding sealing strips are also located on the vertical bars. If the wing 2 is initially only raised, that is moved at its level, the lower and upper sealing strips are released.

At high dead weight of the wing 2, which, for example, by larger-sized sash dimensions, two known carriage, each with two rollers are not suitable to accommodate the sash weight. Carriage assemblies with four carriages coupled to each other by respective connecting rods are known on a window or a door. The aforementioned

Although the design reduces the higher sash weight, but it requires a lot of space, requires a high assembly cost and is very

costly. In addition, the effect is limited by the number of other roles, as a result of the long series of consecutive with

Connecting rods connected carriages and by dimensional inaccuracies of the door or window, and the track and the carriage itself not all roles can transfer the heavy weight on the track, since the rigid bearing of the carriage can not compensate for the dimensional inaccuracies and so the contact of individual rollers to the track is missing, which is also at the expense of the roles and can shorten the life. To remedy this deficiency, but at the same time all

Embodiments of FIG. 5 to be provided with an increased leaf weight, the carriage assembly forms by a front coupled carriage 1 and by means of a connecting rod 10 coupled rear carriage 1 ^' to

Support of the wing 2 a pair of carriages. The essential elements of the carriage 1, 1 ^' each consist of a housing 1 1, 1 Γ for mounting by adjusting the position and attachment of the carriage 1, Γ in the fitting groove 9. Furthermore acts between the housing 1 1, 1 1 ^' after Fig. 3 shows a lifting device 12, wherein on each of the horizontal movement directed side of the housing 1 1, 1 Γ particularly well visible according to Fig. 2 and Fig. 3, a pair of rollers 13 is arranged, which consists of a roller carrier 14 and starting from the central axis

Carriage longitudinal direction of the roller carrier 14 from two pendulum mounted rollers 15, 1 6 is formed. For this purpose, the housing 1 1, 1 Γ and the pairs of rollers 13 are movable on roller bearing elements 17, 18; 19, 20 for example by a

Riveted or stored by dowel pins and form a structural unit of the respective carriage 1, 1 ^' .

According to Fig. 3 it can be seen that the pairs of rollers 13 of the carriage assembly designed symmetrically and identically constructed by using the same components in the carriages 1, 1 ^{'can be} installed. By using the same components of the pair of rollers 13 in the carriage 1 and carriage 1 ^' , the assembly is facilitated as a test of the choice of components of the pairs of rollers 13 fails. For complete load suspension of the wing 2 on the carriage 1, Γ is arranged according to Fig. 2 and Fig. 3 on a central axis 21 of the pair of rollers 13, a pendulum bearing. The pendulum bearing is characterized by a roller carrier 14 arranged on the bore 22 and a rotatable with the bore 22 and the roller bearing element 17, 18; 19, 20 fastened pin 23 is formed. Possible inaccuracies of the wing 2 to the frame 35 or between the rollers 15, 16 and the running rail 3 are automatically compensated by the arrangement of the fulcrum on the central axis 21 of the roller carrier 14.

It can be seen particularly clearly from FIG. 5 that the pin 23 has a shoulder 24 which holds the roller bearing elements 17, 18; 19, 20 across to one

Carriage longitudinal axis of the carriage 1, Γ spaced apart in a predetermined position, so that the pairs of rollers 13 freely movable between the Roller bearing elements 17, 1 8; 19, 20 are guided and the roller bearing elements 17, 18; 19, 20 are freely movable in the fitting groove 9 are positioned. The paragraph 24 determines depending on its width, the smooth rotational movement of the pairs of rollers 13 and the free movement of the carriage 1, 1 ^' within the fitting groove 9, whereby a reliable functionality of the carriage assembly is achieved.

To reduce the frictional resistance and to save another

Operations gear oils and the subsequent maintenance of components, the paragraph 24 is designed as a plain bearing element, and preferably from a

Made of plastic material, wherein the shoulder 24 in conjunction with the pin 23 forms a virtually play-free assembly.

The roller carriers 14 having according to FIG. 2 and FIG

Injection molding produced material, made of a stamped or bent part of an extruded profile. All variants shown are suitable for receiving high weights and manufacturing technology can be easily and inexpensively manufactured. Furthermore, the roller carriers 14 form a simple and stable receptacle for the rollers 15, 16.

The coupled with the actuating linkage 4 and the actuator 6 Eckumlenkung 7 forms with the front carriage 1 of FIG. 2 to 5 a one-piece unit. For this purpose, the housing 1 1 arranged in the longitudinal extent of the fitting groove 9 and directed to fitting groove 9 flat portion 25 which extends with transition into the vertical fitting groove 9 and the deflection of the corner 7 by movable webs 26 receives movable. Due to the integral structure of the carriage 1 with the corner 7, reduce the

Assembly work of the fitting. At the same time is created by the angled at a right angle flat portion 25 a stop edge for the carriage 1 in the horizontal direction and in the vertical direction, so that thus reduce the attack times. In addition, find the items of the corner 7 from existing components of the operating fitting your use, which advantageously the manufacturing cost but also possibly the

Installation costs influenced as conventional assembly tools can be used. In order not to belittle the selection for the use of rollers 15, 1 6 due to the freewheeling dimension of the outer diameter, has the flat portion 25 of the carriage 1 in the region of a pair of rollers, which the Eckumlenkung. 7 is closest, a cutout 27, in which the rollers 1 5, 16 engage. Through the cutout 27, the carriage 1 in integral construction with the corner drive 7 without changing the component height, which would have required a change in the fitting groove 9 in depth, are performed. For this purpose, reference is made to FIGS. 2 to 5, which on the one hand represents the one-piece construction of the carriage 1 and on the other hand shows the cutout 27 in engagement situation of the pair of rollers.

The width of the fitting groove 9 of the wing 2 at the lower horizontal wing spar 8 corresponds to the bearing surface of the top of the carriage 1, 1 ^' arranged flat portion 25 of the housing 1 1 and the flat portion 28 of the housing 1 1 ^' , which at the bottom of the fitting 9 are arranged flat for receiving holes for attachment via fastening means (see FIGS. 2 to 5). The flat portions 25 and 28 of the carriages 1, 1 ^' form the support of the wing 2. In the installed by the fitting groove 9 of the wing 2 concealed state of the carriage assembly of Fig. 1 and Fig. 4, all others are to the

Carriage 1, 1 ^' arranged components, however, and thus formed narrower relative to the width of the fitting groove 9. The arrangement of the movable components of the carriage 1, Γ on the longitudinal central axis, is determined by the width of the sections 25, 28, which in turn are oriented to the width of the fitting groove 9.

A safe operation of the wing element 2, in particular when lifting and when moving horizontally relative to the frame 35, is also achieved in that the carriage 1 at the carriage 1 ^' facing open end 29 and the carriage 1 ^' at the open end 30 to the carriage 1 and illustrated in Fig. 2 and Fig. 3, a coupling element 31 is arranged, which is the

Connecting rod 10 frictionally receives. With adherence to the same position of the carriage 1 and the carriage 1 ^' and connection through the

Connecting rod 10, the wing 2 can be controlled evenly over the

Actuator 6 are raised and lowered, with the

to be absorbed sash weight distributed on the carriages 1, 1 ^' .

Despite high sash weights and reduction of the material of the wing 2 and the frame 35 in view of the visible surface and the cross section due to better optics by enlarging the glass surface, which thus automatically includes a reduction in the dimensions of the fitting groove 9, the design of the carriage assembly according to the invention is suitable in the preceding window or door to be easily and easily mounted and actuated by Distribution of the wing load on the individual rollers 15, 16 to perform with smooth-running and low-wear rolling motion. For this purpose, according to FIG. 5, the housing 1 1, 1 Γ the carriage 1, Γ on the side facing the fitting groove 9 on the sections 25, 28 a fixing pin 32 which in a bore 33, 34 of the lower horizontal wing spar 8 am upper bottom of the fitting groove 9 engages and the carriages 1, 1 ^' positionally positioned. Due to the design, a high shear strength is achieved, so that shorter attachment means, for example

Fixing screws find the use in the wing 2. Likewise, the number of fastening screw of the carriage assembly decreases.

Furthermore, the fixing pin 32 is clearly recognizable from FIG. 3, preferably made of a roll pin. The dowel pin fits into a on the wing 2 of the lower horizontal wing spar 8 at the bottom of the fitting groove 9 arranged bore 33, 34 a form fit. By choosing the tension pin the carriages 1, nahezu in a prefixed position almost free of play and in horizontal

Direction and the direction of movement of the wing 2 held captive. But there are also other embodiments of fixing pins 32 conceivable.

In summary, there is a method for assembling a carriage assembly for hard-to-lift and movable wings 2 of a window or door, consisting of a front carriage 1, which has a coupling element 31 with one end of a connecting rod 10 and the coupling element 31 of a rear carriage ^' the other end of the connecting rod 10 frictionally to support the wing 2 a pair of carriages educating is to connect (see Fig. 2), wherein the carriage 1, 1 ^' each have a housing 1 1, 1 1 ^' , and on each side of the housing 1 1, 1 1 ^' to the carriage longitudinal direction a pair of rollers 13 is arranged, which is formed from a roller carrier 14 and two pendulum mounted rollers 15, 16, wherein the housing 1 1, Γ on the to a fitting groove 9 of a lower horizontal wing spar directed side each have a fixing pin 32, whereby by engaging the carriage assembly in the fitting groove 9 of FIG. 5 of the fixing pin 32 in a bore 33, 34 of the fitting groove 9 a position positioning for the carriages 1, 1 ^'is achieved.
