Description

The invention relates to a carriage according to the preamble of claim 1 as well as on a building window or a building window door according to the preamble Claim 18.

So-called parallel sliding tilt doors or windows are known, for example for Residential spaces used to maximize the opening width for the open door or for the open window without the open door or window sash disturbing into the building space. Opening the closed window or the closed door takes place in such a way that the Wing initially substantially perpendicular to the door or window level from the opening of the frame moves to the inside of the building, i. issued and subsequently moved parallel to the door or window level. Closing then takes place in reverse way. For ventilation, these doors or windows can also be tilted become.

To the movements and furthermore also the locking of the wing at the stick or To enable frame, so-called Parallelschiebe- and tilt fittings known (DE 32 34 677 A1, EP 0 201 717 B1 or DE 299 07 975 U1). These Fittings have additional to other functional elements (eg. Locking elements) u.a. a carriage on the lower part of the respective wing, i. on the lower horizontal or horizontal bar of the Sash is attached. Known carriages consist essentially of each two carriage elements, the bearing elements or bearing housings respectively one end of this lower spar of the sash, i. in the area of wing-closing and opening side are mounted. To the opening movement of the wing allow is on the respective bearing housing a stay arm with one end hinged, hinged at the other end with a running shoe connected, for the parallel sliding movement of the wing in a running rail having engaging track and carriage rollers.

It is also known in these carriages (DE 32 34 677 A1, EP 0 201 717 B1) that Running shoes of the two carriage elements or their housing by a parallel to the running rail extending connecting rod to connect.

Known is a Parallelschiebebeschlag with two each at one end of a lower, horizontal Holmes a sliding door fixed carriage, the over Carriage rollers cooperate with a running rail (EP-A-0 222 995). Of the Carriage at one end of the spar comprises two carriage elements, of which a Lauwagenelement lastaufnehmend and this via a stay with a Bearing for the attachment of the carriage element at the lower horizontal rail of Wing is connected. Another, adjacent carriage element, which only one has only carriage roller and exclusively for controlling the movement of the Wing is used when closing is via a link in Running rail longitudinal direction of the adjacent load-bearing carriage element slidably guided and articulated via a joint or control lever with the Extension arm of the load-bearing carriage element connected.

Especially with multiple glazing, as usual today and because of Thermal protection regulations are also prescribed, have large wings considerable weight, which of the carriage or its roles on the Guide rail must be transferred. For the sake of a possible low-noise operation and to avoid wear on the track rail These roles are usually made of plastic, often made of glass fiber reinforced Plastic (eg polyamide). With increasing sash weight come such Rollers very fast to the limit of their capacity.

Finally, it is also known (DE 200 03 168 U1), in a carriage in the field of two ends of the lower horizontal spar of the casement two in each case To provide carriage elements, namely in each case an outer first carriage element and adjacent to this an additional, relative to the door center further inside attached second carriage element. All carriage elements are each with bearings attached to the lower horizontal spar of the sash and have a running shoe that articulates with the associated via a pop-up Warehouse is connected. Between the two second carriage elements is a Provided link in the form of a connecting rod.

The object of the invention is to show a carriage, which at high Functional safety is also suitable for increased sash weights. To solve this Task is designed a carriage according to claim 1. One Building window or a building window door with such a parallel sliding tilt fitting are formed according to claim 18.

The carriage according to the invention has in addition to the usual provided two outer carriage elements ("first carriage elements) at least one further carriage element ("second" carriage element), which regardless of the first two carriage elements with their own warehouse or Bearing housing can be fastened to the sash and at least one extension arm has its own running shoe with the carriage rollers.

In the embodiment of the invention, each running shoe has two Carriage rollers on, so that a uniform load of these carriage rollers each Running shoe is guaranteed.

The carriage is designed so that each outer first Carriage element is adjacent at least a second carriage element, so that the support of the respective wing substantially on the two sides of this Wing (wing opening and closing side) takes place, and there, where the Multiple glazing over the prescribed by guidelines blocking on the Sash frame supported.

Further advantages of the carriage according to the invention are u. a. in that at least for the outer carriage elements on conventional elements can be used, so no complete redesign is necessary. It already existing parts can be widely used, even for the inner carriage elements. In a modular design are with the Invention using standardized parts carriages with only two Carriage elements, but also carriages for higher load with more than two Carriage elements possible.

In the figures, 1 is generally a building door, namely for example a Balcony or terrace door, which u.a. a stick or frame 2 with a fixed field 3 with glazing and with a movable wing 4 with Sash 5 and with glazing has. The wing 4 is with a Parallel sliding tilt fitting around a lower horizontal, parallel to the wing plane lying axis tiltable and in a direction perpendicular to the plane of the window frame second extending axis out of the frame out or expelled and im issued state parallel to the plane of the frame displaced, namely such that the fully open wing 4 is arranged in front of the fixed field 3.

An integral part of the parallel sliding and tilt fitting is the on lower horizontal spar 5 'of the sash 5 provided carriage, in the Figures 1 - 12 in general with 6 and in Figures 13 - 15 in another possible embodiment is generally designated 6a.

The carriage 6 consists of several carriage parts or elements which in the Figures 1 - 12 are denoted by 7, 8, 9 and 10, from the outer Carriage element 7 in the area of the wing-closing side, from the outer Carriage element 8 in the area of the wing opening side, from the farther inside lying additional or inner carriage element 9, which is the vertical Central axis M of the wing 4 toward the carriage element 7 as flush as possible connects, as well as from the inner carriage element 10, which to the central axis M offset as closely as possible to the carriage element 8 connects.

Apart from minor differences, the carriage elements 7 and 8 and the carriage elements 9 and 10 each mirrored to the vertical Center axis M formed so that it is sufficient below, the carriage elements. 7 and 8 to describe.

For example, as shown in FIGS. 1 and 5, the outer carriage element is comprised 7 from the angular in the illustrated embodiment bearing housing 11, which forms by its angular shape, the two legs 12 and 13, with which the Bearing housing 11 in a suitable manner, for example by screwing on the lower horizontal spar 5 '(leg 12) or on the adjacent vertical Holm 5 "of the sash frame 5 is fixed, on the inside of the wing. 4 On the leg 12 is by means of a hinge 14, the one end of a stay arm 15 to an axis parallel to the axis of the vertical bars 5 "or parallel to Center axis M articulated. The other end of the Ausstellarmes 15 is by means of a Joint 16 about an axis parallel to the axis of the joint 14 on a housing 17th a running shoe 18 hinged. In the elongated housing 17 are two Carriage rollers 19 in a line one behind the other, i. in the longitudinal direction L offset from one another in each case freely rotatably mounted about an axis perpendicular to Axis of the joint 16 and perpendicular to the longitudinal direction L is L. Like the figure 4 is at the outer side provided at the closing or control side Carriage element 7 nor an additional control lever 20 is provided in the essentially serves the wing 4 in the issued state at least as long Lock until the wing 4 is moved when closing in a position in which then the final closing by moving the wing 4 into the pole frame 2 can be done perpendicular to the wing plane. The control lever 20 is shown in the illustrated Embodiment at its one end by means of a hinge 21 on the extension arm 15 hinged, wherein the axis of the joint 21 parallel to the axis of the joints 14 and 16 is arranged. At the other end, the control lever 20, for example, from a pin formed guiding or locking element 22, which in an L-shaped Control cam 23 slides. This is formed on the top of the housing 17, and Although such that the control cam 23 has a longer, in the longitudinal direction L of the Running shoe 18 extending first portion and at the center of the running shoe 18th closer end also still a second, perpendicular or transverse to the longitudinal axis L. forms extending control section.

4 shows the wing 4 in the issued, by the control lever 20th locked position. The locking element 22 engages in the aforementioned second Section of the cam 23 and is by a on the control lever 20th acting spring element 24 biased in this locking position. At the Closing of the wing 4 is then by a fixed stop 25, the locking element 22 unlocked, so that the wing 4 for final closing in the floor frame second can be moved perpendicular to the wing plane and the locking element 22 here slides in the first section of the control cam 23.

As stated above, the carriage element 8 is mirror-inverted to Carriage element 7 made, but does not have the control lever 20.

The carriage element 7 is associated with a further carriage element 9, which Although adjoins the carriage element 7, but opposite to the central axis M offset and therefore referred to as "inner" carriage element 9. The Carriage element 9 consists of the bearing housing 26, which in the illustrated Embodiment of the bearing housing 11 is carried out similarly, but the Leg 13 is omitted, i. the bearing housing 26 is suitably only on lower spar 5 'of the sash frame 5 attached.

On the housing 26 in turn the extension arm 15 is articulated by means of the joint 14, at its other end by means of the hinge 16 on the housing 27 of the running shoe 28th is articulated, wherein the joints 14 and 16 perpendicular to the longitudinal extent L of Running shoe 28 and parallel to the longitudinal extent of the vertical bars 5 "of the Sash 5 or parallel to the central axis M lie. In the housing 27, which in the Detail is shown in Figures 7 - 11 are again in the longitudinal direction L. offset from each other and in a line two carriage rollers 19 freely rotatable stored, in each case about an axis perpendicular to the longitudinal axis L and perpendicular to the axes of the joints 14 and 16.

The housing 28 is at both ends with a coupling portion or Coupling piece 29 made, which one open to the respective end Mounting sleeve with bore 30 forms, in each case one end of a Connecting rod in the manner described in more detail below Clamping can be anchored. Each coupling piece 29 has two for this purpose radial threaded bores 31 (Figures 8 and 9), namely for clamping screws 32nd (eg Figures 5, 6 and 12). The arrangement is further made such that the axes the holes 30 are coaxially with each other and parallel to the longitudinal axis L.

The housing 17, not shown in detail in the figures, is similar to the housing 27, but has only one end, i. on which the running shoe 28th adjacent end of the coupling piece 29 corresponding coupling piece 29 ' with a hole 30 corresponding hole and with threads for Clamping screws. The training is such that when mounted carriage 6 the axis of the coupling piece 29 'and its bore coaxially with the axes the holes 30 of the coupling pieces 29 on the housing 27 is.

Also, the running shoe housing 17 of the carriage 8 has of course at his inside, i. the central axis M end facing such Coupling piece 29 '.

As the figure 4, but also the figure 12 show, the running shoes 18 and 28 of the Carriage elements 7 and 9 or 8 and 10 respectively using the Couplings 29 and 29 'via a shorter connecting rod 33 with each other connected, in such a way that the two joints 14 on the bearing housings 11 and 26 and the two joints 16 on the running shoe housings 17 and 27 with their axes form the vertices of a Gelenkparallelogramms and thus the Ausstellarme 15 of the carriage elements 7 and 9 or 8 and 10 respectively parallel to each other are arranged.

About the coupling pieces 29 on the central axis M side facing the Running shoe housing 27 are the two running shoes 28 of the inside Carriage elements 9 and 10 via a connecting rod 34 of greater length connected with each other.

When mounted in this form carriage 28 are the carriage or Laufschuhrollen 19 all running shoes 18 and 28 in a line in the direction of Longitudinal axis L provided consecutively and engage in a common Running rail 35, which in the region of the lower horizontal Holmes Stock frame 2 or at a local threshold profile is provided. About the Connecting rods 33 and 34 are thus the running shoes 18 and 28 substantially rigidly connected to a running shoe unit, at the on the Austellarme 15th and the bearing housings 11 and 26 of the wings 4 is held. By use each of two running shoes 18 and 27 on both sides of the sash 5 becomes reduces the load on the individual carriage or running roller 19, so that Also high sash weights reliably from the carriage 6 on the track rail 35th be transmitted.

To improve the rigid connection between the two inner Carriage elements 9 and 10 and to avoid a possible lateral Dodge the longer connecting rod 34 is at this at least one Support member 36 is provided, in the illustrated embodiment, approximately in the center of the connecting rod 34. This support element is designed as a slider and slides in the track rail 35. By the support member 36 is a lateral Dodge the connecting rod 34 avoided. This will cause the function, in particular, the precision of the movement of the carriage 6 essential improved, as the adherence to a defined distance between the inner Running shoes 28 is ensured via the connecting rod 34.

Of course, along the connecting rod 34 also several such, with the running rail 35 cooperating support or sliding elements and / or others cooperating with the running rail 35, a lateral deflection of the Guide rod 34 preventing elements may be provided. Also, the Connecting rod 34, for example, as a corresponding, with the running rail 35th co-operating profile over the entire length or at least on one part their length be executed.

It was assumed above that the running shoes 18 and 28 of the Carriage elements 7 and 9 or 8 and 10 via a connecting rod 33rd connected to each other. Of course, other connections conceivable. In a simplified embodiment can continue on the Connecting rod 33 are omitted, as via the connecting rod 34 and the attached to the sash 5 bearing housing 26, the axes of the joints 14 and 16th the inner carriage elements 9 and 10, a defined articulated parallelogram form. Likewise, it is basically conceivable to the longer connecting rod 34 dispense and only the running shoes 18 and 28 on the connecting rods 33rd to connect with each other.

Basically, there is the possibility of the housing 27 in such a way that it both be used for the carriage element 9, as well as for the carriage element 10 can. The housing 27 is for this example, at least in terms of storage the carriage rollers 19 and with respect to the coupling pieces or sections 29 and their distances from the axis of the bearing 16 'for the joint 16 symmetrical to a this axis of the bearing 16 'enclosing and perpendicular to the longitudinal axis L. oriented transverse plane QE formed.

The carriage 6 is particularly suitable for wings 4, in which the sash 5 is made of a wooden or plastic profile. With 37 is still a holder denoted in the middle or approximately in the middle of the spar 5 'attached thereto is and for additional support a not shown, in particular the Bearing housing 11 and 26 staking aperture is used.

FIGS. 13-15 show, as a further possible embodiment, the carriage 6a, in particular for wing 4 with a sash 5 made of a metal profile is determined. The carriage 6a differs from the carriage 6 substantially in that, instead of the bearing housings 11 and 26, bearing housings 11a and 26a are used, which conform to the shape and special requirements etc. of a Sash 5 are adapted from a metal profile. Thus, the bearing housing 11a outer carriage elements 7a and 8a not designed as an angle piece, as in particular, the figure 13 shows. The outer carriage elements 7a and 8a in turn have the hinged over the stay arm 15 running shoe 18, the its inner end with the coupling piece 29 'is provided. The two inside carriage elements 9a and 10a, of which the carriage element 9a is shown in detail in Figure 14 and of which the carriage element 10a relative to the median plane M mirrored to the carriage element 9a executed is, have at their hinged on the extension arm 15 running shoes 28 turn both ends a coupling piece 29 so that in the prescribed manner the tie rods 33 and 34 connect the running shoes 18 and 28 is possible.

The bearing housing 11, 26, 11 a, 26 a and / or the extension arm 15 and / or the Running shoe housing 17, 27 are made for example as die cast metal parts.
