Description

[0001] The invention relates to a carriage for moving a sash of a window or a door, with a base provided for connection to the sash, with a bearing unit for supporting rollers and with an adjusting device having a link guide for height adjustment between the base and the bearing unit, wherein the link guide has a link arranged inclined to the intended sliding direction and a pin arranged on the opposite component and supported in the link.

[0002] For the carriages of sashes, such as sliding doors, height adjustment, and thus the vertical adjustment of the sash, is important to enable the installer to make the correct adjustment during installation. A possible readjustment via the adjustment mechanism is also necessary if the sash settles after installation. This adjustment is crucial for ensuring optimal sealing of the window or door and ease of use.

[0003] A carriage of the type mentioned above is known, for example, from WO 2022 / 037905 A1. In this carriage, a roller part has a height-adjustable roller upper part. The height adjustment of the roller upper part relative to a roller holder is achieved by an adjusting element that can be moved using an adjusting screw. The adjusting element is supported by at least one adjusting element bevel on a pendulum axis of the roller holder and on the roller upper part. The pendulum axis is designed as a pin that can be inserted separately into the roller holder.

[0004] EP 2 881 530 A1 discloses a sliding window with a roller unit in which a pin is attached to a connecting piece. The pin penetrates a slotted guide and a vertical guide and has a radial widening at its free end. Therefore, the pin must be connected to the connecting piece as a separate component at the end of the roller unit assembly through the slotted guide and the vertical guide.

[0005] A disadvantage of the current state-of-the-art technology is that installation is very complex. Furthermore, a pin that must be inserted separately can become displaced during operation of the carriage due to vibration or friction, thus leading to carriage failure.

[0006] The invention is based on the problem of developing a carriage of the type mentioned at the beginning in such a way that it is particularly easy to assemble and has a high level of reliability.

[0007] This problem is solved according to the invention in that the pin forms a structural unit with the bearing unit or the base.

[0008] This design eliminates the need for a pin as a separate component. This makes assembly of the carriage particularly easy. Furthermore, the pin's structural integrity with the bearing unit or base body prevents it from becoming loose during operation. This ensures the carriage's high reliability and exceptional stability.

[0009] The pin could, for example, be pressed into the adjacent component. However, according to another advantageous embodiment of the invention, it contributes to further reducing the manufacturing costs of the carriage if the pin is manufactured in one piece with the bearing unit or the base.

[0010] According to another advantageous development of the invention, the carriage is particularly simple in design if the bearing unit comprises a bearing body supporting the rollers and a guide body containing the link, and if the position of the bearing body relative to the guide body is adjustable by the adjustment device. This design allows the bearing body and guide body to be manufactured with a high degree of stability for the respective different tasks.

[0011] According to another advantageous development of the invention, the stability of the bearing unit is further increased if the bearing body has a vertical elongated hole in which the pin is guided.

[0012] According to another advantageous development of the invention, the stability of the bearing unit is further increased if the guide body has elongated holes arranged in the sliding direction for accommodating the bearing axles of the rollers. This design supports the weight of the wing directly above the guide body on the bearing axles of the rollers.

[0013] According to another advantageous development of the invention, the guide body is designed to be particularly simple in construction if the guide body has two guide plates arranged in parallel and if the guide plates are connected to one another via a cross element.

[0014] According to another advantageous development of the invention, the adjusting device is particularly simple in design if the transverse element has a thread for an adjusting screw of the adjusting device which is supported on the bearing body.

[0015] According to another advantageous development of the invention, the bearing body is designed to be particularly simple in construction if the bearing body has two bearing plates arranged in parallel, if the bearing plates are connected to one another via a support element and if the adjusting screw of the adjusting device is supported on the support element.

[0016] According to another advantageous development of the invention, the carriage can be easily adapted to different wings if the base has a base body intended for screwing to the wing and an adjusting body connected to the slotted guide.

[0017] According to another advantageous development of the invention, the carriage is particularly simple in construction if the pin is manufactured in one piece with the adjusting body.

[0018] According to another advantageous development of the invention, a lateral offset of the carriage can be easily compensated for if the base body has a guide for the adjusting body arranged transversely to the intended sliding direction. When installed, the guide allows horizontal displacement of the adjusting body relative to the base body, transversely to the sliding direction. Furthermore, this ensures particularly high stability of the connection between the base body and the adjusting body.

[0019] To move the sash, after unlocking it, it must first be set aside from the frame. After moving, the sash must be pulled back against the frame, sealing it, and locked. According to another advantageous development of the invention, the setting aside and pulling of the sash relative to the frame can be easily coupled with the locking and unlocking if a control pin is arranged on a coupling rod intended for connection to a drive rod fitting of the window or door, and if the control pin engages a setting guide of the actuating body.

[0020] According to another advantageous development of the invention, a basic adjustment of the adjusting body relative to the base body is particularly simple if the control pin is designed to be eccentrically adjustable in the setting gate of the adjusting body.

[0021] According to another advantageous embodiment of the invention, transverse forces arising during operation of the carriage assembly transverse to the sliding direction can be easily supported if the bearing unit has a sliding body on a side facing away from the rollers for lateral support on a guide rail. Preferably, the bearing unit also supports a brush extending into the guide rail.

[0022] According to another advantageous development of the invention, it contributes to further increasing stability if the sliding body connects the bearing plates of the bearing body to one another.

[0023] According to another advantageous development of the invention, it contributes to reducing friction when adjusting the adjusting body if sliding elements are arranged between the base body and the adjusting body.

[0024] The invention permits numerous embodiments. To further clarify its basic principle, one of them is shown in the drawing and is described below.
