Description

l5 20 25 30 35 522 669 2 band with a roller running against, for example, a person's fingers.

In order for the overhead sliding door to be easy and manageable to hoist up and lower, doors of this type are often provided with wires resiliently connected in a balance spring, which wires are preferably arranged symmetrically in engagement with the door leaf in a lower corner of said door leaf. The wires then follow the side edges of the door leaf vertically until they reach the balance spring.

A further problem with the prior art is that the guide rail, in which the door leaf is slidable, describes a curved path, the runners which are connected to the door leaf engage. The web is at the upper edge of the door opening, in which web is curved so that the door will be more flexible when it is opened and closed. In order for the upper section of the door leaf to still reach towards the upper part of the door opening, the runners which are connected to the upper part of this upper section from one direction are arranged in separate paths which lead this particular runner all the way to the upper side corner of the door opening. When the balance spring is relatively bulky, it is preferably arranged a little further in from the door opening in order to be free from outer walls, etc.

This in turn means that the runner holders carrying runners in the separate paths described above risk catching the traction means when the gate is close to its closed position due to the wire often breaking into the area which the runner and its holder must then pass .

This, of course, complicates the desired raising and lowering of the overhead sliding door. The user is then forced to release the wire from any runner device with his fingers in a step which, in accordance with the previously mentioned, entails an increased risk of squeezing.

SUMMARY OF THE INVENTION The object of the present invention is therefore to provide a roof sliding door device for minimizing the risk of crushing injuries occurring, in particular in connection with opening and closing of the door. Another object of the present invention is to provide a robust and secure high quality overhead sliding door.

A further object of the present invention is to provide a device at a overhead sliding door, which device means that the overhead sliding door can be opened and closed in a simple manner without hooking in traction means which run between the balance member and the lower part of the overhead sliding door on either side. of the overhead sliding door.

These objects are achieved according to the invention in that the device of the type indicated in the introduction is given the features which appear from the following claim 1.

Preferred embodiments are set out in the dependent claims 2-11.

The device according to the invention at a roof sliding door which has guide rails extending along the vertical sides of a door opening and a door leaf which is composed of a number of interconnected sections via horizontal folding paths which at the side edges of the door leaf carry runners which are guided along the guide rails , wherein the guide rails in their respective upper part merge into a bend and continue as a substantially horizontally arranged guide rail, and have at least one drive or balancing device which is connected to the door leaf via at least one traction member. The substantially horizontally arranged guide rail comprises two paths, a first path receiving a top runner arranged in the upper section of the door leaf, and a second path receiving the runners arranged in the other sections of the door leaf, the paths being arranged on each side of the traction member.

This solution offers many advantages, such as the risk of squeezing between, for example, the runners and the guide rail and between the side edge of any door leaf section and the guide rail in connection with, above all, opening and closing of the door. By means of this device according to the invention, free passage past the pulling means in connection with the closing position of the door leaf is allowed. Furthermore, the device according to the invention achieves a greater freedom in the choice of the stretch and position of the traction member in relation to the runners and the door construction. The invention allows the runners and the respective tracks in which the runners are set up to become substantially encapsulate without the slidability of the overhead sliding gate being made more difficult.

According to a particularly preferred embodiment of the invention, the runners are compared with the top runner in the opposite direction relative to their carriers and in relation to said top runners. By arranging the respective runners in this way, good encapsulation with a relatively simple profile is made possible. The device according to the invention preferably has a profile in which the webs are integrated. In the profile that acts as a guide rail, the runners are slidable back and forth. The profile is preferably arranged as a covering protection. This is to prevent external access of the tracks and runners, thereby reducing the risk of squeezing.

In addition, the integrated profile prevents dirt and debris from falling into the tracks of the guide rail and makes it difficult for the runners to move along the tracks.

Conveniently, the separate paths run in the substantially horizontally arranged guide rail parallel to each other. This means that the overhead sliding door is given a smooth and smooth operation when opening and closing. Preferably, the balancing device is arranged on the overhead sliding door in the form of a balancing spring in close proximity to the top of the door opening. Other variants of resilient attachment and means for deflecting the traction member are of course also conceivable and can be used to replace the balance spring in the embodiments of the invention described below. The current design of the door opening largely determines the possibility of finding sufficient space to place the balance spring in the desired location and enable the maximum opening height of the door to be achieved.

In accordance with one embodiment of the invention, tensioning means, resiliently connected to the balance spring, are provided at their other end in each side of the door leaf, preferably in its lower part. . Preferably, the traction members are of the linen type, chain type, belt type, or timing belt type.

According to an embodiment of the invention, the separate paths in the substantially horizontally arranged guide rail are arranged parallel to a lateral displacement relative to each other, which forms a horizontal distance in the area between the runners in the paths, seen substantially perpendicular to the paths. axial direction. By means of this device according to the invention, free passage past the pulling means in connection with the closing position of the door leaf is permitted.

This is achieved by said pulling means running in the formed area between said paths. In accordance with the invention, the runners comprise roller means. This ensures a smooth ride with low friction of the runners according to the invention. In an alternative embodiment of the invention, the runners comprise sliding means. Of course, the runners in an embodiment of the invention can also comprise both rollers and sliding means, which are preferably arranged at different places of the door leaf.

Of course, the above embodiments can be freely combined as well as the various steps of the process within the scope of the invention. It is also understood that a lifting device can be included in the overhead sliding door to provide lifting force, so that opening and closing are not perceived as heavy. This lifting device is suitably connected to a power supply of some kind. In one embodiment of the invention, the opening and closing method is automated and controllable from a control panel.

Description of Preferred Embodiments A preferred embodiment of the invention will be described in the following. The described exemplary embodiments are not to be construed as limiting but are given by way of example only.

Fig. 1 shows a substantially conventional overhead sliding door which consists of a door leaf denoted in its entirety by 1, which is divided into a number along mutually articulated joints 2 interconnected articulated door leaf sections 3. The number of door leaf sections depends on height - the one in the current door opening, for which the overhead sliding door is intended. At each of the vertical side edges of the door opening extends a vertical guide rail part 4. The door leaf sections 3 are connected to and guided by the guide rails via runners which are suitably located in the rails impellers mounted on shafts attached to the door leaf sections. The door weight is balanced by means of a balance spring 8. Denoted by 9 is a drive device for operating the door leaf between the open position of the assignment and the closed position, in which the latter position the door leaf covers the door opening in question (not shown in the drawing).

Figures 2a-2b schematically show how the guide rail 4 in which the door leaf 1 is slidable describes a curved path 10, in the upper edge of the door opening, in which path the runners 10 which are connected to the door leaf 1 engage. The track is curved to make the gate more flexible when it is opened and closed. In order for the uppermost section A of the door leaf 1 to still reach out towards the upper part of the door opening, the runners 10, which are connected to the upper part of this upper section A from one direction, are arranged in separate first paths in the substantially horizontal guide rail 6 which leads this particular top runner all the way to the respective upper side corner of the door opening. Figs. 2a-2b show in a simplified manner how this bearing works seen in a cross section in one of the two guide rails from the side. The balancing device 8 can be provided in several ways. The balancing device 8 In Figs. 2a and 2b, an alternative balancing device i is indicated, for example, may be designed as a linen drum. in the form of a dotted spring 33 which cooperates with the tension member 30 via a deflection member. Other variants of balance springs 8 which are not shown are also conceivable within the scope of the invention.

Preferably, the traction member 30 is arranged so that it intersects and crosses the path of the top runner when the door leaf is moved in the vicinity of its closed position. To illustrate this, Fig. 2a shows the location of the top runner in a first path in the guide rail 6 when the door opening is slightly open. Fig. 2b shows the location of the top runner in a first path in the guide rail 6 when the door opening is closed.

Fig. 3 shows a preferred embodiment of the invention in a cross section III-III. The substantially horizontal guide rail comprises two tracks, in which a top runner is arranged slidably in the axial direction of the guide rail 6, i.e. substantially perpendicular to the cross section of the figure.

Fig. 4 shows a preferred embodiment of the invention in a cross section IV-IV. The substantially horizontal guide rail comprises two tracks, in which a top runner 10 is arranged slidably in the axial direction of the guide rail 6, i.e. 4 substantially perpendicular to the cross section of the figure. In Fig. 1, the runners 10 in the second web according to a preferred embodiment of the invention have a lateral displacement relative to the top runner.

According to a preferred embodiment of the invention, the separate paths in the substantially horizontally arranged guide rail 6 are arranged parallel to a lateral displacement relative to each other, which forms a horizontal distance in the area between the runners 10 in the paths, which distance is indicated by an arrow in Figures 3 and 4 across the area between the runners 10 in the tracks. The device according to the invention allows free passage of the top runner in the first path past the traction member 30 in connection with the closing position of the door leaf. When the cross-sections in Figs. 3 and 4 are taken in an area where the pulling means, preferably in the form of a rope, is not arranged, the area indicated in the figure should primarily illustrate the clearance achieved by displacing the two paths in laterally in relationship to each other. This in combination with the runners 10 arranged in the other sections of the door leaf being supported by carrier 31, whose runners compared to the top runner are opposite relative to their carriers and in relation to said top runners, means that the top runner passes the traction member with a clearance in in the vicinity of its closing position in accordance with a preferred embodiment of the invention. This is achieved by said traction means running in the formed area between said paths. The traction member 30 is suitably guided through a hole in the guide rail 6 further to the balance spring 8. Preferably, the traction member is arranged to run abutment against the support portion 31 of the runner. In accordance with a preferred embodiment, the guide rail 6 is designed as an integrated profile 32 which holds the runners and their paths and at the same time encapsulate them with the aid of the door leaf side, so that the risk of squeezing is minimized.

In accordance with a preferred embodiment of the invention, Fig. 5 shows a cross section of the vertical guide rail 4 in which a runner 10 is arranged movably in relation to the extent of the web. The runner 10 is supported by a support portion 31 which in turn is arranged in a door leaf section. When the runner 10 is moved, the door leaf 1 is dragged into the movement in relation to the guide rail 4. Advantageously, the corresponding construction is used in the continued roof rail.

Fig. 6 is a preferred embodiment of an integrated profile which constitutes the substantially horizontal guide rail seen in perspective. The invention thus allows the profile according to one embodiment to be extruded, but can also be obtained according to an alternative embodiment by bending or roll-forming a blank. It is not considered to offer those skilled in the art any difficulty in selecting the right material, for the constituent components to provide the device according to the invention. The profile may be composed of several separate parts.

The invention has been described above in the form of exemplary embodiments with some suggestions for alternative embodiments, but the invention can of course also be varied in other ways within the scope of the appended claims without departing from the basic idea of the invention. Thus, of course, the device according to the invention can also be applied to gates of a different design than the one shown.
