JP3309989B2 - Ascending folding door - Google Patents

Abstract

The invention concerns a lifting folding door (3), containing: two primarily vertically extending rails (4), arranged each on one side of the opening (2) to be closed by the door (3); a number of panels (8) hinged together, each of them guided by both rails; guiding means (6) connected at the top of each of the rails for guiding the panels such that, when moving upward, they are folded together in zigzag fashion by means of their hinge connections (12, 13) in primarily horizontal direction above the rails; operating means for driving at least one of the panels in vertical direction, in which the guiding means are designed for gradually deflecting the panels in horizontal direction, starting from the vertical movement. As a result of these steps, a purely vertical movement is gradually converted into a movement of a horizontal component, so that the dynamic forces acting on the respective elements are less, and therefore the speed can be significantly increased.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a flip-top door. The ascending folding door comprises a plurality of panels joined by hinges and two main vertically extending rails,
Rails are arranged on both sides of the opening closed by the door to guide the panels. It further comprises a plurality of guide rails arranged next to each vertically extending panel. The guide rails extend to the side of the top of each rail that extends vertically to guide the panel. Therefore, when the panel is moved upward, it is folded in a substantially horizontal zigzag shape. The panel comprises a first guide element for guiding the panel in a vertically extending rail and a plurality of second guide elements for guiding the panel in the guide rail. The plurality of second guide elements are equal in number to the guide rails. The rail is adapted to determine lateral movement and rotation of the panel.

Such a lift door is known from U.S. Pat. No. 3,618,656. This known folding door comprises two pairs of panels. A guide roller is rotatably connected to the panel. The guide rollers form a second guide element and guide the panel through respective guide passages. The guide passage is formed by a groove. Due to the rotatably connected guide rollers, the door can be raised from an extended position to a folded position without undue stress on the door actuator.

It is an object of the present invention to provide another ascending folding door that can be opened and closed at high speed.

This object is achieved according to the invention by a rising folding door of the type described above which features a second guide element securely mounted on the panel.

The second guide element itself, which is positively connected to the panel of the folding door, is, for example, an Australian patent AU-B-20968 /
Known from 92. However, Australian patent AU-B-20968 / 92 has only one pair of guide rails for all second guide elements, i.e. all panels,
And a lift door of the type in which the guide rail is not adapted for determining the lateral movement and rotation of the panel. Besides that, U.S. Pat. No. 3,618,656 does not disclose the use of a second guide element which is securely connected to a lift door of the type of the subject of U.S. Pat. No. 3,618,656.

In order to prevent the second guide element from following the wrong guide rail, the flip-up door of the invention preferably selectively guides each second guide element to the corresponding guide rail. Selection means.

The present invention will be described with reference to the accompanying drawings.

It is a modification of the embodiment shown in FIG.

FIG. 1 shows a wall 1 with an opening 2
Is closed by the flip-up door of the present invention.
The whole of the ascending folding door is indicated by 3. The ascending folding door has two rails 4, 5, each of which is arranged on the side of the opening 2. Plate-like guide means 6, 7 with suitable grooves are arranged at the top of each rail 4, 5, respectively. The ascending folding door further has a panel 8 shown in broken lines in FIG. As shown in FIG. 1, when the door is open, the panel 8 includes the guiding means 6,
Folded together between seven.

Guide means 6, 7, also indicated by broken lines, for protecting the folded panel 8 are mounted in the assembly unit 9. This assembly unit is connected to the wall 1 at the side 10. FIG. 1 further shows a method of mounting the unit. This method will be described later.

FIG. 2 illustrates the first embodiment of the present invention in detail.

FIG. 2 shows the rail 4 as viewed from the opening 2 and the guiding means 6 arranged on the rail 4. Tracks of the type of groove 11 are arranged on the rail 4. The pins connected to the panel 8 are guided in the grooves 11.

In this particular embodiment, the door has six panels 8, each door being zigzag-foldable, having an outer hinge 12 on one side and being joined to an inner hinge 13 on the inside. Have been. Inner and outer hinges 12, 13 so that when the door is folded, the outer hinge remains outside the door and the inner hinge moves inside the door.
Is arranged. The outer hinges 12 are each connected to a pin guided by a groove 11. Outer hinge 12
Have a corresponding pin on the other side. The pins are guided by rails located on the outside sides of the open door, with corresponding grooves formed in the rails.

Of course, it is also possible to apply the invention to doors with different numbers of panels, for example 4, 8, 10 or 12 panels. It is also possible to apply the invention to an odd number of panels, for example 5 or 7 panels. However, in this case, a greater number of panels must be guided.

Each pair of panels 8 joined by an inner hinge 13 has an upper panel 8 with guide pins 18, 19, 20 which also extend into the groove 11. I have. As the panel moves up, each pin 18, 1
9, 20 must bend and move for good folding. Therefore, the plate-shaped guide means 6 is
It has deviated trajectories like 15,16,17. Of course, the danger that exists is that the pins connected to the outer hinges 12 move upward in the deflection grooves 15, 16, 17 and the guide pins
There is a risk that the pins will move into the wrong deflection groove, as the 18, 19, 20 will continue to follow the main trajectory of the type of extension of the groove 11.

Therefore, groove 11, the main track, is the outer hinge
Like the pins connected to 12, they are wider. The width of the deflection grooves 15, 16, 17 is reduced to prevent a wide pin from entering the deflection grooves. This is illustrated in FIG.
It is clear from Similarly, the deflection grooves 15, 16, 17 are
It is narrower. The same applies to pins 18, 19 and 20. Pins 18, 19 and 20 are on the outer hinge
It is narrower than the guide pin connected to 12. Furthermore, deflection grooves
15, 16, 17 are deeper than the groove 11 at the position where the guide means is arranged. Since each pin is always guided through the groove 11, the groove 11 in the rails 3, 4 is of course the same depth as the groove 17. As a result of the different depths, the pin 18 is guided in the groove 17 as it moves upward, followed by the pin 19 in the groove 16 and the pin 20 in the groove 15.

Obviously, the extension of the groove 11 is shallower than the groove 15, so that only the deep pins are retained by the groove 15 after the deepest groove 15 is deflected. The same applies to other deviating orbits. Importantly, in the present invention, the deflection grooves 15, 16, 17 are gradually deflected, and the dynamic deflection force is small even when moving at high speed. Therefore, the device is suitable for high speed.

In this embodiment, the pins 18, 19, and 20 are arranged on the panel 8. Of course, it is also possible to connect a pin to the innermost hinge 13. Further, different methods are possible. That is, the pins connected to the inner hinge 12 and the guide pins 18, 19, 20 can be arranged in a fork-like structure and guided along the guide path.
Again, it is possible to vary the thickness and / or depth.

In the embodiments described above, the pins 18, 19, 20 are always arranged on the top panel of each pair. Of course, it is also possible to couple the pin to the bottom panel or to couple the pin to the inner hinge 13. This can be applied to other embodiments.

FIG. 4 shows a particularly suitable embodiment for high speed, where each pin has a dedicated guideway. The inner hinge 13 of the present embodiment is connected to pins 20, 19, 18, respectively,
Each pin moves in the separated grooves 23, 22, and 21, respectively. The separated grooves 23, 22, 21 are formed to perform necessary functions. Again, the important thing is that groove 21,
22 and 23 are gradually deflected, so that the moving speed of the door can be increased. In FIG. 4, each pair of panels has a different width. Of course, the width of the panels can be the same. When the guide means is arranged as in FIG. 4, the guide pins are connected to the panel.

Further, in the case of the embodiment shown in FIG. 4, the grooves 21, 22, 23 are
On the lower side it faces outwards, so that panel 8
Is biased to an outer closed position in contact with a seal (not shown).

FIG. 5 shows a device for selecting a pin by means of a switch of the type "point" or switch element. This embodiment has a track of the type of a groove 24, which exclusively guides the pins 18, 19, 20 connected to the panel 8 or the inner hinge 13. The pin connected to the outer hinge 12 moves along a groove not shown in the drawing. Again, there are deflection tracks of the type of deflection grooves 25, 26 and 27, respectively. At the position where the deflection groove 25 branches off from the main groove 24, the switch element 28
Are arranged. When the switch element is held in the position shown in the drawing, the moving pin follows the main groove. When the deflecting element 28 is located at the other position, the pin follows the deflecting groove, shown as deflecting groove 25. To operate the arrangement, a mechanism with a cam 30 is used. The cam 30 is arranged in a deflection groove 26 located above the unique deflection groove 25,
It is connected to the deflection element 28 by a lever device 31. Spring for holding the deflection element 28 in the normal position shown in the drawing
There are 32 mo. That is, whenever the pin moves within the deflection element, one of the cams is activated. The deflecting element is therefore moved from a groove located below the deflecting position. Obviously, even in the case of a sharp deflection as shown in the present embodiment, the operation is smoothly performed according to the present invention. The drawing schematically illustrates this principle.

The fourth embodiment shown in FIG. 6 differs in the type of the selection mechanism. The groove 11 of the present embodiment has no branch. Furthermore, the inner hinge has no individual guide elements or the guide pins are not connected to the panel 8 near the inner hinge 13. Alternatively, the upper portion of the groove 11 has an enlarged portion 37, and the upper panel of each pair of panels 8 has a cam 38 at the position of the outer hinge 12.
Is joined to. That is, the cam 38 that rotates about the hinge 12 is securely connected to the lower panel 8 of the pair of panels to which the outer hinge 12 is connected.

In addition, between each pair of panels 8 is arranged a tension spring, which is schematically indicated by reference numeral 39 in the drawing.

FIG. 7 shows an enlarged detail of a unique cam structure. FIG.
As shown in the figure, the cam 38 has an annular portion 40 at the end of the head,
The enlarged portion 37 also has an annular portion 41. The annular portions 40 and 41 allow the cam 38 to rotate easily within the enlarged portion 37.

Furthermore, this embodiment has a lifting mechanism of the type of a cord 42, which is connected at its lower end to the lower end of the lowermost panel 8 and to the uppermost panel 8 Is guided by a guide pulley 43 located above
It is wound on a winding drum 44. Winding drum 44
Is operated, for example, by an electric motor. Obviously, such a lifting mechanism also exists in the embodiments described above. Of course, other lifting mechanisms could be used instead of this lifting mechanism, such as, for example, an annular chain or a manual lifting mechanism. Of course, this lifting mechanism is also applicable to all embodiments.

In the embodiment shown in FIG. 6, the cord 42 is not connected to a hinge. However, it is also possible to guide the cord 42 in a zigzag manner around the hinges 13 and 12, in which case the cord can exert an individual folding force and the tension spring 39 can be eliminated.

When the lower end of the cord 42 moves upward, the lower end of the lowermost panel 8 is pulled upward, and the other panel, which is the panel 8 in this embodiment, follows. Cam38
Cannot rotate because it is enclosed in the groove 11, and the lower three pairs of panels are not folded. As a result, the uppermost pair of panels 8 is always folded.

As shown in FIG. 6, this process continues until the upper pair of panels is fully folded and the uppermost cam 38 is within the uppermost enlarged portion 37. Subsequently, as the only possibility, the next upper pair of panels 8 is folded. Subsequently, the next upper cam 38 reaches the enlarged portion, and the next pair of panels is folded. This process continues, depending on the number of panels used, until all panels have been folded and the situation shown in FIG.

A tension spring 39 is arranged between each pair of panels to enhance the folding action. Of course,
It is also possible to omit the pair of tension springs 39.

Of course, it is also possible to combine the widened cams of FIGS. 6 and 7 with other embodiments. By spreading the cam, it is possible to prevent the outside of the panel from bending in the guide.

As in the embodiment described above, it is also possible to guide the code in a zigzag manner.

An embodiment that is substantially identical to the embodiment of FIG. 2 is shown in FIG. 8 differs from the embodiment of FIG. 8 in that the deflection groove has an enlarged portion indicated by 48 at the position where the deflection groove deviates from the groove 11. The purpose of these enlargements is to deflect the pins and panels progressively more than in the embodiment described above by means of FIG. In this embodiment,
A tension spring 39 is arranged between each pair of panels. As a result, the pin and the panel follow the deflection groove, and the pin and the panel are folded together. In order to guide the pins into the appropriate grooves by means of these forces directed towards the deflection grooves, the depth of each groove is reversed as in FIG. Thus, groove 15 is the shallowest in the embodiment of FIG. 8, groove 16 is somewhat deeper than groove 15, and groove 17 is the deepest. Of course, the main groove 11 is deepest, so that the pins connected to the outer hinge 12 are prevented from moving into the deflection groove. As shown in the embodiment of FIG. 2, these pins can be thickened.

However, it is also possible to guide the pins connected to the outer hinge into separate rails. A configuration similar to that of FIG. 4 is possible, but as can be appreciated, grooves 21, 22 and
23 are integrated.

The embodiment shown in FIG. 9 corresponds in many respects to the embodiment shown in FIG. 4, except that the guide pins 18, 19, 20 have guide wheels 48, 49, 50, respectively. Furthermore, the guide pins are connected to the panel 8 by arms 51, 52, 53, respectively. The guide wheels are separated grooves 21,
Good guidance in 22, 23 is ensured, so that a low friction movement is possible. Guide pins arranged on the outside
12 further has a guide wheel 54. A further difference of this embodiment is that an odd number of panels 8 are used, and the top side of the top panel is folded inwards.

Moreover, other panels, such as a single upper panel, can also have guide wheels. All grooves have a shape that matches the shape of groove 21.

FIG. 10 shows the structure of the panel in more detail. Each panel 8 is formed by a sandwich-like structure having an inner wall 55 and an outer wall 56, wherein the inner wall 55 and the outer wall
A filling material 57 in the form of plastic foam is arranged between the filling material 57 and the filling material 57. At the bottom, the panel is contoured 58
And as a single unit in the inner wall, for example by snap rivets, screw connections, or by welding or gluing, as shown in the figures. Each panel is also closed at its upper end by a similar outer portion 58. Therefore, in this embodiment, it is possible to form the entire panel by extrusion. However, this is not an essential application of the present invention. Of course, after extrusion, the panels must be filled with foam. For good closure between the panels when the door is closed, a rubber profile 59 with projections 60 is used, the projections 60 fitting exactly into the respective profile 58. For this purpose, the profile 58 has a saw-tooth 61. Therefore, it is also possible to use the outer portion 59 in other ways. Again, the outer portion 59 can be coupled to one of the outer portions 58, for example, by vulcanization or bonding of rubber. Therefore, a good seal in a closed situation can be achieved.

To join the panels together, hinges 62 are used,
One piece of hinge 62 is connected to profile 58 by screw 63. The outer portion 59 is partially cut at the position of the hinge. This ensures that no additional space has to be provided for the hinge, and that a good seal is achieved by the closing profile having a portion of one edge 64.

FIG. 11 shows the apparatus of the above-described embodiment as viewed from the outside. Of course, in the present embodiment, a plurality of panels are used, but the upper end of the uppermost panel and the lower end of the lowermost panel are configured to be folded inward. For this purpose, an additional guide rail 65 extending directly below is provided. This is shown in FIG. 12 as a whole. It should be noted that the embodiments shown in the figures are also applicable to odd panels. Therefore, the upper panel is provided with additional guide pins guided by guide elements 21
Has 51. This can further limit the height of the upper panel. Furthermore, of course, an additional arm 66 with an additional guide pin 67 is mounted.

In embodiments not shown, guide wheels 48, 49,
A ball is used instead of 50. The effect is that the sphere can rotate in any direction and the friction in contact with the side and bottom of the rail can be minimized. Of course, balls are difficult to install. Theoretically, it is also possible to use V-shaped rails, in which the spheres make uniform contact at two points. This simplifies the problem of supporting the sphere.

FIG. 13 shows a detailed view of a device for preventing the tilting of the panel of the ascending folding door. This arrangement is formed by arms 68, which are hinged 69 to the panel 8
Is joined to one of the A bush 70 is coupled to the arm, in which pin 71 is axially biased by a spring. The pin 71 is connected to a fork 72, and a shaft 73 is arranged through an outer end of the fork. A wheel 74 is mounted on the shaft 73. The wheel 74 rotates against the wall of one of the grooves 21, 22 or 23 or rotates in the main groove 11.
At each corner, each panel 8 can be provided with such a device. However, if the panels are interconnected, then only two such devices need to be placed on each panel. The arm 68 is securely connected to the panel 8, or the arm 68 and the arm 51, 52 or 53
It is also possible to combine any one of the above.

It should be noted that the spheres in the above paragraph perform exactly the same function.

FIG. 14 shows a different variant, in which supports of the type of a U-shaped element 75 are arranged in order to prevent the outside of the element from moving downward during folding of the element. These elements 75 are formed with recesses 76, which are rounded on the outside at their lower ends. Pins 77 are arranged at the top end of each odd-numbered element (counting from the top) to engage the recess. The pins engage the recesses, essentially preventing the front of the panel from moving downward. Furthermore, the pins perform a predetermined guiding action. Of course, panel pin 77
In the position, a suitable recess is formed in the panel.

In the present embodiment, the operation is improved by clamping the pin 77 in the concave portion 76. This is because a material having a large coefficient of friction, such as
Can be achieved by lining up in a row. More importantly, the pins 77 and elements 75 of each panel are located at different distances from the edge of the door opening, which results in the pins being located differently from the edge of the door opening. This prevents the pins of different panels from being obstructed by the elements 75 of the pins belonging to other panels.

If the number of panels is even, the upper panel is shorter than the remaining panels and the free end of the upper panel is not fixed by the cam. Therefore, it is possible to provide a specific guide groove in the guide means, in which the guide pin mounted on the associated panel is guided.

In the variant shown in FIG. 15, a sprocket 78 is arranged in the upper part 24 of the groove, which acts as a closing element or a movable switch. The sprocket 78 is adjustable in height and can be coupled to different deflection grooves at different locations.

Obviously, many other different mechanisms can be selected, and therefore it is also possible to electrically control the deflection elements 28, 29 of the embodiment shown for example in FIG. For this arrangement to be effective, the same guide rail 24 can be used to guide the pins arranged on the outer hinge. However, more importantly,
The deflection groove deflects progressively, so that the most possible action can be achieved. It will be appreciated that the selection mechanism also has a positioning function.

It is also possible to separate the selection function of the selection means from the guidance function. Thus, for example, it is also possible to use an orienting wheel, which can control the guide means in the form of a pin and select an appropriate deflection groove.

In the embodiments described above, opening and closing are hardly described, but opening and closing can be performed, for example, by a cable connected to the lowermost panel. In this embodiment, the cables are connected to the panel on both sides of the opening to be closed. However, it is also possible to use, for example, four cables. The four cables are connected in pairs to the lowermost panel on either side of the opening to be closed. One cable of the pair is coupled to the outside of the panel, and the other cable is coupled to the inside of the panel. The cables are subsequently connected to a panel located above. With this connection, the cable extending on the inside is connected to the hinge which is folded inward, and the cable extending on the outside is connected to the hinge which is folded outward.
The cables are each wound on a single drum or a pair of drums located on one side of the door. One of the cables must be guided over the door opening. With this configuration, the need for a through shaft can be eliminated.

Finally, referring again to FIG. 1, the assembly of the flip-up door of the present invention is described. For this purpose, the assembly unit 9 is arranged, for example, on a transport vehicle 35. The transport vehicle 35 has a carrier 36 that can be raised and rotated. The above-mentioned assembly unit 9 is disposed on the carrier 36, and the carrier 35
It is driven into the opening to be closed. Until the assembly unit 9 placed on the carrier reaches the correct position, the carrier 36
Is moved upward and rotated. Further, the carrier 36 is properly connected by the side 10 and a suitable connecting member. Subsequently, the individual rails 4, 5 are appropriately arranged and connected, and subsequently, after the application of the various actuating elements, the power supply is connected and the unit is placed in operation. Subsequently, the transport vehicle 35 is removed.

Instead of a liftable carrier, for example, a forklift truck can be used. Of course, other lifting mechanisms,
Or it is also possible to use a hoisting mechanism, for example a hoisting crane. The hoisting mechanism is provided with means for connecting the mounting unit by, for example, a level gauge.

Obviously, the proper movement of the heavy elements by the lifting platform allows a particularly convenient and beneficial connection.
