Description
` -C~21 44554 Vertical Travel Door This invention concerns a vertical travel door that opens from the closed position by moving downwards into an underground trench. The door moves up and down two vertical posts located at each side, and is raised and lowered by a vertical travel drive mechanism.
Such vertical travel doors have so far been equipped with hydraulic piston lifting mechanisms, where the hydraulic piston mechanism is accommodated under the floor, and lifts the door structure from below, as shown by AT-B 382 201 or US-A 4 922 655. The door structure is guided by underground posts arranged to the side of the door panel where required. This means that when the door is raised in the closed position it is actually not very safe or stable.
Despite the fact that the door is not particularly rigid it needs a relatively large space underground to accommodate the vertical travel drive mechanism and door guides, meaning that such vertical travel doors have been implemented only where small dimensions are concerned, and have in practice proved hardly worth installing.
This invention is therefore designed to overcome the above problem by providing a door of the type mentioned at the beginning, featuring a more straighfforward and space-saving construction that is both more stable and has a multitude of applications.
CA21 $4554 The invention solves the problem by using side-mounted guides that reach over the entire path the door travels while opening and closing. The side-mounted guides are linked at the top and bottom by cross braces that are joined to the door frame. The lifting mechanism is located in the vicinity of the top cross brace and the door is suspended on chains or spindles that run down the vertical guide posts. The door frame ensures that the door structure is bothrigid and stable, especially in the closed position where the door panel is supported securely. Another feature is the lifting mechanism which has been taken out of its previous underground location, and is now located up in the vicinity of the top cross brace, so that the door is easier to operate due to it now being suspended, and in addition the narrower slot in the floor is quite sufficient to accommodate the vertical travel guides, the lower cross brace (if required) and the door panel when lowered. To install the door it is necessary only to excavate a narrow trench in the floor, just wide enough to be able to bring in the foundation with support frame and carry out the foundation lining work, thusenabling this design to save on both labor and space at the same time as providing a stable, self-supporting construction which significantly widens the range of implementation and applications of this type of vertical travel door.
This door can then be implemented not just as an outside door for workshops and garages etc., but also as a wall element used as part of a conservatory, pavilion or other building, that can be lowered into the ground when required.
The door panels can be made of a variety of materials to suit the application inquestion, e.g. they can comprise a framework into which different panels can be fitted, made of glass or insulation elements etc.
CA21 4~554 A variety of different lifting mechanisms can be implemented. A hydraulic cylinder can be mounted on the underside of the top cross brace for example, linked with the top edge of the door. A more practical system however is a vertical travel drive mechanism involving a spindle drive system where the spindles are connected to the door via anti-twist nuts so that the spindles can be driven by a simple electric motor (or hydraulic or pneumatic unit), also providing a self-locking door suspension system.
Another type of vertical travel drive mechanism with certain advantages is a chain-driven system where the door is suspended from a drive shaft which runs on bearings within the recesses of the vertical guide posts. The sprockets from which the chain is suspended are located at the top end of the vertical guide posts. This drive system can be set with precision and adjusted to on-site conditions with ease. Because the same drive shaft operates the chains on both sides of the door, uniform vertical travel is ensured.
A particularly favorable configuration is achieved by installing an additional idler sprocket on each side of the door so that the chains - which are anchored to the door frame at one end by an adjustable, spring-loaded restraint - run down over the idler sprocket (that takes the weight of the door) before going upto the drive sprocket so that a pulley effect is achieved. The pulley system enables the door to be moved with precision and with the minimum of force.
If a malfunction or damage were to occur to the door drive mechanism, the door is fitted with a safety brake to prevent it falling, possibly causing a dangerous situation. The door panel is fitted with at least one safety brake near its bottom edge. The safety brake comprises a spring-loaded lever that, when activated, applies a brake pad to the vertical guide post.
The lever is operated by a trigger linked to the door panel suspension which prevents the brake being applied so long a force is acting on it. Providing the weight of the door panel is acting on the door panel suspension the trigger holds the safety brake lever in the open position. If the door suspension no longer has a force acting on it (e.g. because a chain has broken etc.) the trigger is activated and the spring-loaded lever applies the brake to the vertical guide post, braking the fall of the door panel. If the door panel is raised via the door panel suspension the trigger acts on the brake lever again, releasing the brake.
In order to ensure exact tracking and prevent the door from moving back and forth within the vertical guide posts, the door panel is fitted with lateral support elements which are adjustable and engage with the runners in the vertical guide posts. Due to the fact that the lateral support elements are adjustable, the door panel moves easily and yet with precision along the vertical guide postrunners. The lateral support elements can take the form of rollers or glide blocks etc. and additional sets can be implemented at each end of the door panel if required.
So that large surface areas of door panels or walls can be handled, two or more door panels can be arranged side by side if a shared vertical guide post is inserted between them. This enables a vertical travel door or wall (in the case of greenhouses or conservatories for example) to be made up of several segments, each of which can be operated separately if required.
For safety and accident p!evention reasons the top of the door panel isequipped with a safety bar which is fitted with pressure switches connected to the vertical travel drive mechanism. If, when the door panel moves from the open position and starts moving upwards towards the closed position, the safety bar touches an object or person the pressure switches immediateiy switch off the vertical travel drive, thereby preventing damage or injury.

Fig. 1 shows a partial section through the vertical travel door viewed from the side.
Fig. 2 shows section ll - ll from Fig. 1 enlarged.
Fig. 3 shows a partial section through a vertical travel door which has been modified to demonstrate one possible configuration, viewed from the slde.
Fig. 4 shows section IV - IV from Fig. 3.
Fig. 5 shows a horizontal section through another possible configuration.
With reference to Fig. 1, a vertical travel door (1 ) comprises a door frame (2)which is partially embedded in the ground (B) and partially protruding upwards, two vertical guide posts (3), an upper cross brace (4) and a lower cross brace (5), where required. The door panel (6) moves up and down between the two vertical guide posts (3). Door movements between the upper closed position and the underground open position are powered by the vertical travel drive mechanism (7).
The configuration shown in Fig. 1 and in Fig. 2 involves vertical travel drive mechanism (7) comprising a spindle drive (8) with a drive shaft (9) which turns within the upper cross brace (4). Bevel gears (10) act as a transmission to the spindles (11) which turn inside the vertical guide posts (3). Anti-twist nuts (12) connected to the door panel (6) move up or down the spindle (11 ) depending on which direction it is rotating. The door panel (6) is fitted with adjustable lateral support elements (13) which steady the door against the runners (14) of the vertical guide posts (3) and can be raised and lowered with ease by spindle drive (8).
-C~21 44554 The configuration shown in Fig. 3 and Fig. 4 involves vertical travel drive mechanism (7) comprising a chain drive (15) with a drive shaft (9) turning on bearings within top cross brace (4) on which sprockets (16) are mounted in the region of vertical guide posts (3) from which chains (17) are driven to move door panel (6). Each sprocket (16) is assigned an idler sprocket (18) which is connected to the suspension of door panel (6) and forms a pulley system (19) with sprocket (16) and chain (17). At one end the chain (17) is attached to an adjustable, spring-loaded restraint (20) on door panel frame (2). The chain runsfrom the restraint to idler sprocket (18), back up over sprocket (16), from which it hangs free inside vertical guide post (3). By rotating drive shaft (9) the sprockets (16) can be turned in one direction or the other so that the pulley system (19) moves the idler sprocket (18) up or down, moving the door panel (6) with it. The door panel (6) is guided by lateral support rollers (21 ) - or glide blocks - that move up and down the guide runners (22) mounted on the vertical guide posts in such a way that lateral support roller (23) can be adjusted to keep the door absolutely steady.
Door panel (6) is fitted with a safety brake (24) along its lower edge. A pivoting brake lever (25) is mounted at each end and has a brake block (26) which is applied to vertical guide post (3). The brake lever (25) is spring-loaded towards the braking position via spring (27). The door panel suspension point (28) -which is idler sprocket bearing (18) in this case - is mounted on trigger (29) that is fitted with an arm (39) that holds the brake lever (25) in the open position.Providing the weight of the door panel (6) acts on trigger (29) holding it against the stop (31 ) on the underside of the door, arm (30) holds brake lever (25) away from vertical guide post (3) and the brake is open. As soon as the suspension gives, counter-spring (27) can move the brake lever (25) against the trigger (29) so that brake pads (26) are forced against the vertical guide posts (3) and the door panel is held fast.
C~ 2 1 44554 As a safety feature the door panel (6) can be equipped with a safety bar (32) along its top edge. The safety bar is spring-loaded and is equipped with pressure switches (33) that are connected to the vertical travel drive mechanism '7? so that if the door is moving from the open position up to the closed position and safety bar (32) touches a person or object obstructing the path of the door the vertical travel drive mechanism is switched off immediately.
Instead of using a safety bar equipped with pressure switches, an electric eye system can be fitted to switch off the vertical travel drive mechanism if a person or object obstructs the path of the door panel.
Protection strip (34) along the vertical guide posts not only protects the guideand drive components, but also prevents the system being tampered with, which could be dangerous.
With door framework (2) and vertical travel drive mechanism (7) being located in the vicinity of the upper cross brace (4), this vertical travel door system provides a stable construction which is capable of bearing heavy door panels, and features a relatively narrow, space saving design which means that to install such a door only a narrow trench need be excavated to accept the foundation, the door frame construction and the lowered door panel. In addition the vertical travel door system has many applications. Apart from being used as a door it can also be implemented to take wall elements of a conservatory (or similar building) where, as shown in Fig. 5, a number of door panels (6) can be arranged next to each other when a shared vertical guide post (35) is inserted in between. The door framework then encompasses all the door segments, and each door panel can be configured to operate separately.
Such vertical travel doors have so far been equipped with hydraulic piston lifting mechanisms, where the hydraulic piston mechanism is accommodated under the floor, and lifts the door structure from below, as shown by AT-B 382 201 or US-A 4 922 655.

The door framework then encompasses all the door segments, and each door panel can be configured to operate separately.
