Problems solved by technology

However, such liftgates would be unsuitable for fast-moving operations
[0009] Moreover, since the spring members have to lift the dead weight of the vertical parts of the two guide rails during each opening movement, the spring members for returning the vertical parts are subject to severe wear
In this connection, the specific problem is that when the spring force drops, it is no longer possible to ensure that the connection to the lintel section can be obtained in a reliable fashion
As a result, the door leaf cannot be smoothly moved into the lintel portion, which then breaks the door leaf and causes problems in the operation of the lift door

Embodiment Construction

[0048] according to figure 1 In the figure, the lifting door 1 comprises a frame 2 with a guide rail 3 for the door leaf, but the guide rail 3 is not shown in this figure. figure 1 Shown is a view of the frame 2 on the left hand looking out from the door opening. In the following descriptions, in most cases, only the area on one side of the door will be discussed, while the other side of the door opening presents the frame settings including the guide rails, etc. formed according to the mirror image. The lift gate 1 also comprises a drive unit 4 comprising a motor 41 and a sealing device 5 .

[0049] The guide rail 3 comprises a web portion 31 which, in the practical example, has the form of a helix. When the lift door 1 is in the open state, the door leaf is received therein in the form of a contactless coil in the region of the door web. The guide rail 3 also comprises a vertical portion 32 in which the door leaf assumes the closed state of the lift door 1 . At the frame...

Abstract

The invention relates to a lifting door (1), comprising a movable door leaf (6) formed by slats (61) pivotably connected to each other and comprising building-mounted frames (2). Lateral guides (3) for the door leaf (6), which have a vertical section (32) and a lintel section (31), and frame sealing elements (51) of a sealing device (5) are arranged thereon. The frame sealing elements close a gap between the door leaf (6) and a section of the frames (2) facing the door opening when the lifting door (1) is closed. The vertical sections (32) of the guides (3) can be moved perpendicularly to the door leaf plane and are supported on the frames (2) in a stationary manner in the direction of motion of the door leaf (6; 6'), whereby the door leaf (6) can be pressed against the sealing device (5) in the direction of the outside of the door when the lifting door (1) is closed. The invention further relates to a frame (2), a guide (3), and a corresponding method. Thus an improved sealing effect between the door leaf (6) and the door opening can be created, wherein at the same time high reliability during operation is achieved and high motion speeds are enabled.

Description

technical field [0001] The present invention relates to lift doors comprising a movable door leaf and a building-mounted frame arranged on either side of the door opening, wherein the mutually facing transverse guides of the leaves are arranged at the frame, and each transverse guide Both comprise a vertical section and a lintel section, wherein the door leaf is formed by slats pivotally connected to each other, and the door leaf covers the door opening in the closed position, wherein the door leaf is guided by transverse rails so that when the lift door is in the open condition be accommodated in the lintel portion and, when the lift gate is in the closed position, be accommodated in the vertical portion of the guide rail, wherein the vertical portion of the guide rail is mounted on the frame for displacement, whereby, when the lift gate is in the closed position In this state, the door leaf can be displaced in a direction towards the outside of the door, and wherein the driv...
