The invention relates to a window or a door according to the preamble of claim 1.
WO 93/18261 A1 discloses a sliding door whose rollers can be pivoted about the axis of a running rail. This prevents the transfer of very high sash loads. The fittings of the sliding door cannot be arranged flexibly.
DE 77 00 410 U1 discloses a sliding door having a sash that can be detached from a fixed frame of the sliding door. To detach the sash, the sash is pivoted over a carriage on the sliding door. In order to transfer the load on the sash, solid bushings must be provided due to the leverage required to pivot the sash. A flexible arrangement of the fittings of the sliding door is not possible.
Carriages with a sash part that can be fixed to a sash and a roller part that can be moved in a straight line to the sash part are known from DE 10 2012 213 786 B3 and EP 2 829 679 B1.
EP 3 431 692 B1 discloses a generic door. A control arm (“support means 22”) of this door can only be moved in one direction. This means that one sash of the door can only be moved with little control relative to a fixed frame of the door. Furthermore, the door fittings cannot be arranged flexibly.
It is therefore an object of the invention to provide a window or a door whose sash is precisely guided in a structurally simple manner and whose fittings can be flexibly arranged on different sash profiles in order to allow for individually constructed windows or doors.
This object is achieved according to the invention by a window or a door according to claim 1. The dependent claims reflect preferred developments.
The object according to the invention is thus achieved by a window or a door having:
The window or door is characterized by a high degree of flexibility and can be implemented with a wide variety of sash sizes and sash profiles. Furthermore, the linear movements of the roller part in combination with the positively controlled slot on both sides guarantee a particularly precise movement of the sash from or to the fixed frame.
The terms “above,” “below,” “horizontal,” “vertical,” and the like refer to the assembled state of the window in a building.
In a particularly preferred embodiment of the window or door, the control arm is arranged on a horizontal sash beam. The control arm is preferably supported on the fixed frame horizontally and/or perpendicular to the main plane of the fixed frame. A plurality, in particular, any number, of control arms can be arranged on a horizontal sash beam. The multiple control arms can be designed to be identical.
Preferably, the control arm has the slot and the drive rod has the pin guided in the slot. This allows the drive rod to be made the same width throughout, which further simplifies the construction of the window or door.
The slot defines a recess, preferably in the form of a through-recess. The slot can completely enclose the recess.
The control flanks extend in particular, on both sides of the movement path of the pin in the slot.
The roller part can have an additional roller to enable the carriage to run more smoothly and to transfer a greater load.
The sash may have a handle for operating the drive rod. The movement of the handle can be transmitted to the drive rod by a gear of the sash.
Further preferably, the first groove is formed with the drive rod on the underside of the sash.
Any threshold that may be present is considered part of the fixed frame.
In a particularly preferred embodiment of the invention, the control arm is connected to the roller part by means of a connector. The connector enables positive control of the roller part via the drive rod, so that the sash is guided in a particularly controlled and precise manner.
The connector can be cranked and/or angled.
Particularly preferably, the connector is designed to transmit both compressive forces and tensile forces between the roller part and the control arm.
The connector may have a hinge. The connector preferably has multiple hinges.
The hinge can be designed in the form of a stiff-back chain for transmitting compressive and tensile forces.
The connector may comprise multiple tab-shaped elements connected via one or more hinges.
In a further preferred embodiment of the connector, it has an adjustment option so that the ends of the connector, which are arranged on the control arm or roller part, can be adjusted vertically and/or horizontally relative to one another. This allows the control arm and carriage to be arranged particularly flexibly on different profiles for sashes or fixed frames.
The connector may be designed to have multiple parts. Two parts of the connector can be locked together in different positions, either detachably or non-detachably. Two parts of the connector can be pluggable and/or clipped. Two parts of the connector can be connected in a form-fitting manner. The parts that can be locked together in different positions can be made of spring steel.
The connector can have multiple through-recesses for variably receiving of a pin for adjusting the connector.
Alternatively or additionally, the connector may have an adjustment option at one end or at both ends. The connection of the connector to the control arm and/or the roller part may have an adjustment option.
In order to divert forces for detaching the sash from the fixed frame and for pulling the sash towards the fixed frame into the fixed frame, a support part can be arranged or formed on the control arm which is supported directly on the fixed frame, in particular, not on the running rail. The support part is preferably in the form of a roller and/or is finger-shaped. The roller can be mounted, in particular, with a roller bearing, to facilitate the detachment the sash from or the pulling of the sash towards the fixed frame. The support part preferably extends perpendicular to the main plane of the control arm.
The carriage can have a projection on both longitudinal sides of the running rail to prevent the carriage from derailing in the event of heavy sash loads transverse to the main plane of the sash or fixed frame. These projections are particularly advantageous if no support part is used.
The control arm can be pivotally mounted on the sash. Preferably, the control arm is pivotally mounted on a faceplate of the sash.
The roller part can be arranged and/or aligned parallel to the first groove. Preferably, the carriage is arranged parallel to the first groove.
The sash can have a second groove which runs at least in sections, in particular, predominantly, preferably completely, parallel to the first groove, wherein the carriage is arranged in the second groove. The second groove preferably runs at least along the underside of the sash.
The carriage can be arranged flush with the control arm on the sash in order to achieve a particularly space-saving arrangement of the carriage.
The window or door may have an additional carriage which is arranged next to the carriage in relation to the extension of the drive rod. The additional carriage may have a roller part with a roller. The roller part of the additional carriage can be coupled to the roller part of the carriage. The additional carriage can be constructed identically to the carriage.
Alternatively or additionally, a carriage can have multiple roller parts. The roller parts can be arranged next to one another with respect to the extension of the drive rod.
One or more roller parts can be coupled to the control arm by a connector and thus be positively controlled.
In addition to the features described here, the sash may have, on its upper side, an upper side drive rod in an upper side groove of the sash and an upper side control arm which is movable by the upper side drive rod, wherein the upper side control arm is supported directly or indirectly on the fixed frame in order to convey both forces for detaching the sash from the fixed frame and forces for pulling the sash towards the fixed frame from the sash to the fixed frame. Multiple, in particular, any number of, upper side control arms can be arranged on the upper side of the sash.
The first groove is preferably formed circumferentially, so that the upper side groove represents a portion of the first groove.
The upper side drive rod can be designed to be identical to, or a mirror image of, the drive rod. Alternatively or additionally, the upper side control arm can be designed to be identical to, or a mirror image of, the control arm.
The upper side control arm can be supported on the fixed frame via an upper side support part. The upper side support part can be constructed identically to the support part. Preferably, the upper side support part is in the form of a roller and/or is finger shaped.
In an independent aspect of the invention, the invention further relates to a fitting arrangement with a carriage with a roller that is movable on a running rail, the carriage having a sash part that can be mounted on a sash of a window or door and a roller part having the roller, wherein the roller part is movable transversely, in particular, perpendicularly, to the running rail in a straight line relative to the sash part in order to move the sash towards a fixed frame of the window or door or away from the fixed frame, wherein the fitting arrangement has an actuatable drive rod that can be guided in a first groove of the sash, the fitting arrangement having a control arm that can be supported directly or indirectly on the fixed frame, wherein the fitting arrangement has a slot on the control arm and a pin guided in the slot on the drive rod and/or a slot on the drive rod and a pin guided in the slot on the control arm, the slot having control flanks on both sides in its longitudinal direction, so that a displacement of the pin in the slot in a first direction can cause the sash to be detached from the fixed frame in a positively controlled manner and a displacement of the pin in the slot in the second direction opposite to the first direction can cause the sash to be pulled towards the fixed frame in a positively controlled manner.
The fitting arrangement can have all the features and variants described here for the window or door.
Further advantages of the invention can be found in the description and the drawings. Likewise, according to the invention, the aforementioned features and those which are to be explained below can each be used individually or together in any desired combinations. The embodiments shown and described are not to be understood as an exhaustive list, but, rather, have an exemplary character for the description of the invention.
The sash 14 has a sash profile 18 on which a fitting arrangement 20 is installed. The fitting arrangement 20 allows the sash 14 to move relative to the fixed frame 12. The fitting arrangement 20 is provided at least on the underside of the sash 14, in the present case at least on the underside and the upper side of the sash 14.
A carriage 22 is provided for moving the sash 14 parallel to the central main plane 16. The carriage 22 has a sash part 24 and a roller part 26 with a roller 28. The roller 28 runs on a running rail 30 of the fixed frame 12.
The sash 14 can be locked to the fixed frame 12, in particular, to latching elements not shown here. For locking, the sash 14 can be moved transversely, in particular, perpendicularly, to the extension of the running rail 30 towards the fixed frame 12. To unlock the sash 14, the sash 14 can be moved (“detached”) from the fixed frame 12 transversely, in particular, perpendicularly, to the extension of the running rail 30 away from the fixed frame 12. To achieve this movement of the sash 14 transversely to the extension of the running rail 30, a control arm 32, in the present case a control arm 32 and an upper side control arm 34, is provided. The upper side control arm 34 can be constructed identically to or as a mirror image of the control arm 32. Preferably, two control arms and two upper side control arms are provided to evenly position the entire sash 14. Optionally, at least one additional control arm and/or one additional upper side control arm may be provided. Additional control arms/additional upper side control arms may be provided to press the sash 14 evenly and tightly against the fixed frame 12.
The control arm 32 is actuated by a drive rod 36. The drive rod 36 runs in a first groove 38 of the sash profile 18. The upper side control arm 34 is actuated by an upper side drive rod 40. Since the first groove 38 in the present case is formed circumferentially on the sash profile 18, the section of the first groove 38 on the upper side of the sash 14 represents an upper side groove 42.
The control arm 32 is supported on the fixed frame 12 by a support part 44. The support part 44 is supported directly on the fixed frame 12. It is designed in the form of a roller. The support part 44 can be guided in a guide groove 46 of the fixed frame 12. The support part 44 preferably extends transversely, in particular, perpendicularly to the main plane of the control arm 32.
The upper side control arm 34 is supported on the fixed frame 12 by an upper side support part 48. The upper side support part 48 is supported directly on the fixed frame 12. It is designed in the form of a roller. Preferably, the upper side support part 48 is constructed identically to the support part 44. The upper side support part 48 can be guided in an upper side guide groove 50 of the fixed frame 12.
The control arm 32 is still supported on the fixed frame 12 via the roller 28 on the running rail 30. For this purpose, the roller part 26 is connected to the control arm 32 via a connector 52.
If the drive rod 36 is moved with the pin 60 in a first direction 66, the control arm 32 pivots out in the direction of an arrow 68. This preferably corresponds to detaching the sash 14 (see
When viewing all the figures of the drawing in combination, the invention relates to a window or a door 10. The window or door 10 has a fixed frame 12 and a sash 14 movable relative to the fixed frame 12. The sash 14 is supported on a running rail 30 of the fixed frame 12 via at least one carriage 22 with respectively at least one roller 28. The sash 14 can be moved transversely, in particular, perpendicularly to the main plane 16 of the fixed frame 12 by a control arm 32, wherein a roller part 26 of the carriage 22 moves in a straight line with respect to a sash part 24 of the carriage 22. The control arm 32 is supported on the fixed frame 12 via the roller 28 of the roller part 26 and/or via a support part 44. The control arm 32 is preferably actuated by the longitudinal movement of a drive rod 36, wherein the movement is imparted via a pin 60 which is guided in a slot 62. The slot 62 guides the pin 60 on both sides with both control flanks 64a,b, except for the play necessary to move the pin 60 in the slot 62.
