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 generic term Claim 18.

So-called parallel sliding tilt doors or windows are known, for example for Living spaces are used to open the largest possible opening for the to achieve open door or for the open window without the open door or Window sash interferes with the building. Opening the closed window or door is done in such a way that the Sash initially essentially perpendicular to the door or window plane from the opening of the frame to the inside of the building, i.e. issued and then is moved parallel to the door or window level. The closing then takes place in vice versa. These doors or windows can also be tilted for ventilation become.

To the movements and also the locking of the wing on the stick or To enable blind frames are so-called parallel sliding and tilt fittings known (DE 32 34 677 A1, EP 0 201 717 B1 or DE 299 07 975 U1). This Fittings have additional functional elements (e.g. Locking elements) etc. a carriage on the bottom of the respective wing, i.e. at the lower horizontal or horizontal spar of the Casement is attached. Known carriages consist essentially of each two carriage elements, each with bearing elements or bearing housings one end of this lower spar of the casement, i.e. in the area of the wing closing and opening side are mounted. To the opening movement of the wing enable, is an extension arm on the respective bearing housing with one end pivoted, the other end articulated with a running shoe is connected, for the parallel sliding movement of the wing in a track engaging track and carriage rollers.

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

Especially with multiple glazing, as is common today and because of Thermal protection regulations are also prescribed, have large-area wings considerable weight, which from the carriage or its rollers on the Guide rail must be transferred. For the sake of one if possible low-noise operation and to avoid wear on the running rail These roles are usually made of plastic, often made of glass fiber reinforced Plastic (e.g. polyamide). With increasing wing weight such come Rollers very quickly to the limit of their resilience.

The object of the invention is to show a carriage that also for increased Wing weights is suitable. A carriage is appropriate for solving this task formed the claim 1. A building window or a building window door with such a parallel sliding tilt fitting are according to the Claim 18 trained

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 independent of the first two carriage elements with its own warehouse or Bearing housing is attachable to the casement and on at least one extension arm has its own running shoe with the roller wheels.

In the embodiment according to the invention, each running shoe again preferably has two Carriage rollers on, so that an even load on these carriage rollers each Running shoe is guaranteed.

The carriage is preferably designed such that each outer first Carriage element is adjacent to at least a second carriage element, so that the support of the respective wing essentially on both sides of this Wing (wing opening and closing side) takes place where the Multiple glazing over the block prescribed on guidelines on the Supports the sash.

Other advantages of the carriage according to the invention exist u. a. in that at least for the outer carriage elements on conventional elements can be used, so no completely new construction is necessary. It Existing parts can largely be used, including for the inner carriage elements. In a modular training are with Invention using standardized parts carriage with only two Carriage elements, but also carriages for higher loads with more than two Carriage elements possible.

1 in the figures is generally a building door, namely, for example, one Designated balcony or patio door, which among other things a stick or frame 2 with a fixed field 3 with glazing and with a movable wing 4 with Has sash 5 and with glazing. The wing 4 is with a Parallel slide and tilt fitting around a lower horizontal, parallel to the sash level horizontal axis tiltable and in a perpendicular to the plane of the frame 2 extending axis out of the frame or movable and in the issued state can be moved parallel to the plane of the frame, namely such that the fully open wing 4 is arranged in front of the fixed field 3.

An essential part of the parallel sliding and tilting fitting is the am lower horizontal spar 5 'of the sash 5 provided carriage which in the Figures 1-12 generally with 6 and in Figures 13-15 with another possible embodiment is generally designated 6a.

The carriage 6 consists of several carriage parts or elements which in the Figures 1-12 are designated 7, 8, 9 and 10, namely from the outside 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 which further inside lying additional or inner carriage element 9, which for vertical The central axis M of the wing 4 is offset against the carriage element 7 as flush as possible connects, and from the inner carriage element 10, which to the central axis M offset connected to the carriage element 8 as flush as possible.

Apart from minor differences, the carriage elements are 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 7th and 8 to describe.

As shown for example in Figures 1 and 5, there is the outer carriage element 7 from the angular bearing housing 11 in the illustrated embodiment, which through its angular shape forms 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 Spar 5 "of the sash 5 is attached, on the inside of the sash 4th On the leg 12 is by means of a hinge 14 one end of an arm 15 around an axis parallel to the axis of the vertical bars 5 "or parallel to Center axis M articulated. The other end of the extension arm 15 is by means of a Hinge 16 about an axis parallel to the axis of hinge 14 on a housing 17th a running shoe 18 articulated. In the elongated housing 17 there are two Carriage rollers 19 in a line, i.e. in the longitudinal direction of the running shoe L offset from each other freely rotatable about an axis that is perpendicular to Axis of the joint 16 and perpendicular to the longitudinal direction L of the running shoe. Like the figure 4 shows, is on the outer provided on the closing or control side Carriage element 7 an additional control lever 20 is provided, which in essentially serves to keep the wing 4 in the issued state at least as long lock until the wing 4 is moved into a position when closing, in which the final closing by moving the wing 4 into the frame 2 perpendicular to the wing plane. The control lever 20 is shown in the Embodiment at one end by means of a joint 21 on the extension arm 15 hinged, 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 has an example of a pin formed guide or locking element 22, which in an L-shaped Control cam 23 slides. This is formed on the top of the housing 17, and in such a way that the control curve 23 a longer, in the longitudinal direction L of Running shoe 18 extending first portion and at the middle of the running shoe 18th closer end also a second, perpendicular or transverse to the longitudinal axis L. trending control section forms.

FIG. 4 shows the wing 4 in the issued position by the control lever 20 locked position. The locking element 22 engages in the aforementioned second Section of the control cam 23 and is by a on the control lever 20th acting spring element 24 biased in this locking position. At the Closing the wing 4 is then by a fixed stop 25, the locking element 22 unlocked so that the wing 4 in the stick frame 2 for final closing can be moved perpendicular to the wing plane and the locking element 22 here slides in the first section of the control curve 23.

As stated above, the carriage element 8 is a mirror image of the Carriage element 7 manufactured, but does not have the control lever 20.

Another carriage element 9 is assigned to the carriage element 7, which connects to the carriage element 7, but opposite this to the central axis M offset and is therefore referred to as the "inner" carriage element 9. The Carriage element 9 consists of the bearing housing 26, which is shown in the Embodiment is similar to the bearing housing 11, but the Leg 13 is omitted, i.e. the bearing housing 26 is only in a suitable manner lower spar 5 'of the sash 5 attached.

The extension arm 15 is in turn articulated on the housing 26 by means of the joint 14, at its other end by means of the joint 16 on the housing 27 of the running shoe 28 is articulated, the joints 14 and 16 perpendicular to the longitudinal extension L of the Running shoe 28 and parallel to the longitudinal extension of the vertical bars 5 "of Casement 5 or parallel to the central axis M. In the housing 27, which in Detail shown in Figures 7-11 are again in the longitudinal direction L. offset against each other and two carriage rollers 19 freely rotatable in a line stored, each around 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 section or Coupling piece 29 made, which is an open to the respective end Fastening sleeve with bore 30 forms one end in each Connecting rod in the manner described in more detail below Clamping can be anchored. For this purpose, each coupling piece 29 has two radial threaded bores 31 (FIGS. 8 and 9), specifically for clamping screws 32 (e.g. Figures 5, 6 and 12). The arrangement is still such that the axes of the bores 30 lie coaxially with one another and parallel to the longitudinal axis L.

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

The running shoe housing 17 of the carriage 8 naturally also has its own inside, i.e. the center axis M facing such an end Coupling piece 29 '.

As FIG. 4, but also FIG. 12 show, the running shoes 18 and 28 are the Carriage elements 7 and 9 or 8 and 10 each using the Coupling pieces 29 and 29 'with each other via a shorter connecting rod 33 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 corner points of a joint parallelogram and thus also the extension arms 15 of the carriage elements 7 and 9 or 8 and 10 each parallel to each other are arranged.

About the coupling pieces 29 on the side facing the central axis M of 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.

In the carriage 28 assembled in this form, the carriage or Running shoe rollers 19 of all running shoes 18 and 28 in a line in the direction of Longitudinal axis L are provided in succession and engage in a common one Track 35, which in the region of the lower horizontal spar of Floor frame 2 or is provided on a threshold profile there. About the Connecting rods 33 and 34 are essentially the running shoes 18 and 28 rigidly connected to one another to form a running shoe unit on which the extension arms 15 and the bearing housing 11 and 26 of the wing 4 is held. By using it of two running shoes 18 and 27 on both sides of the sash 5 the load on the individual carriage or running shoe rollers 19 is reduced, so that Even high sash weights reliably from the carriage 6 to the running rail 35 be transmitted.

To improve the rigid connection between the two inner ones Carriage elements 9 and 10 and to avoid a possible lateral Evasion of the longer connecting rod 34 is at least one on this Support element 36 provided, in the embodiment shown approximately in the middle of the connecting rod 34. This support element is designed as a slider and slides in the track 35. Through the support member 36 is a side Avoiding the connecting rod 34 avoided. This will make the function especially the precision of the movement of the carriage 6 is essential improved since maintaining a defined distance between the inner Running shoes 28 is ensured via the connecting rod 34.

Of course, several such, supporting or sliding elements interacting with the running rail 35 and / or others interacting with the running rail 35, a lateral evasion of the Guide rod 34 preventing elements may be provided. It can also Connecting rod 34, for example as a corresponding one, with the running rail 35 interacting profile along the entire length or at least on a part their length.

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 33 are interconnected. Other connections are of course also possible conceivable. In a simplified version, the Connecting rod 33 are dispensed with, because of the connecting rod 34 and the on the casement 5, the bearing housing 26 fastens the axes of the joints 14 and 16 of the inner carriage elements 9 and 10 a defined articulated parallelogram form. It is also basically conceivable to approach the longer connecting rod 34 dispense with and only the running shoes 18 and 28 via the connecting rods 33 connect with each other.

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

The carriage 6 is particularly suitable for sash 4, in which the sash 5 is made from a wooden or plastic profile. At 37 there is still a holder referred to, which is attached in the middle or approximately in the middle of the spar 5 ' is and for additional support of a not shown, especially the Bearing housing 11 and 26 staking aperture is used.

FIGS. 13-15 show the carriage 6a as a further possible embodiment, which in particular for sash 4 with a sash 5 made of a metal profile is determined. The carriage 6a differs from the carriage 6 essentially characterized in that instead of the bearing housing 11 and 26 bearing housing 11a and 26a are used that conform to the shape and special requirements, etc. Casement 5 are adapted from a metal profile. So is the bearing housing 11a outer carriage elements 7a and 8a not designed as an elbow, such as 13 also shows in particular. The outer carriage elements 7a and 8a in turn have the running shoe 18 articulated via the deployment arm 15, which is attached to its inner end is provided with the coupling piece 29 '. The two internal carriage elements 9a and 10a, of which the carriage element 9a 14 is shown in detail and of which the carriage element 10a based on the center plane M mirror image of the carriage element 9a has, in turn, their running shoes 28 articulated via the extension arm 15 at each end a coupling piece 29, so that in the prescribed manner the connecting rods 33 and 34 connect the running shoes 18 and 28 is possible.

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

The invention has been described above using exemplary embodiments. It understands is aware that numerous changes and modifications are possible without thereby leaving the inventive concept on which the invention is based.
