• An arrangement 1 in accordance with the present invention is eminently suited to being used in conjunction with a door, but can also be used in conjunction with other covering elements which are so arranged as to be capable of closing an opening 2 and of being opened, which arrangement consists of a moving door leaf 3, etc., which is so arranged as to be capable of being formed to adopt the desired path of the door and of being guided at the respective lateral edges 3A and 3B of the door by means of guide grooves 4, 5 which extend along said path.
• the door leaf 3 appropriately consists of a number of door leaf elements
• Guide grooves 4 running essentially vertically along the door opening 2, situated on the respective Lateral edges 3A, 3B of the door, and attached to the end face of the deer, etc., are so arranged as to be attached in a previously disclosed fashion to guide grooves 5 formed into a folded shape.
• each of said guide grooves 5 is folded in such a way that it extends in the form of a spiral essentially along its respective mounting surface 8A, 9A and preferably along a mutually identical plane.
• the spiral-shaped guide grooves 5 can be attached to the end surfaces 8A, 9A of two end walls 8, 9 of a door arrangement 1 executed in the form of a door cassette 10, which end walls are held at a relative distance from one another and face one another.
• the aforementioned end walls 8, 9 can be connected to one another via at least upper braces 11, 12, and preferably also via lower braces 13, 14, which extend across the door leaf 3 and its desired path, and which are capable of being attached via screwed connections 15 to flanges 16 on the end walls 8, 9 executed in the form of plates.
• the door leaf 3 can be supported between said two end walls 8, 9, so as to form a unit which can be ready assembled at the factory where the door is manufactured, and which can be installed easily at the desired location in a door opening 2.
• the door cassette 10 also consists of balancing springs 20 of a previously disclosed kind for the door, extending appropriately between a central attachment 17, for example, and lateral wall attachments 18, 19, in order to facilitate actuation of the door leaf 3 as it is opened and closed. Said balance spring arrangement 21, which previously had to be lifted up to the intended installation position above the door opening, can now also be incorporated into said cassette unit 10, as will be appreciated from the drawings.
• a cable drum 23, 24 attached to a spring rotating shaft 22 and situated at the outer end of each spring can be attached by each of its door cables 25 to the door leaf 3, appropriately to the outermost door leaf element 3 1 of the large number of door leaf elements 3 1 -3 n arranged in a row.
• the cable drums 23, 24 are thus mounted rigidly in relation to the spring-rotating shaft 22, whereas the springs 20 are ridigly attached at their ends 20A, 20B to a wall attachment 18 and 19 and to the shaft 22.
• the two cable drums 23, 24 can exhibit cable attachments 26 and can be provided with cable grooves 27 which extend in the form of a spiral around the periphery of said cable drum. Said cable drums 23, 24 are so adapted as to compensate for the irregular extension of the spiral guide groove, which varies due to the fact that, amongst other things, the guide groove 5 can be transformed from the groove parts 5 1 , 5 2 , 5 3 , 5 4 with essentially straight form, which can also be connected to one another by means of groove curves 5 5 , into a curved groove section 5 6 .
• each cable drum 23, 24 which are appropriately executed in mirror image of one another, exhibiting a diameter which, over that part of the cable drum on which the cable 25 is so arranged as to Lie, varies over the width of the cable drum, appropriately in such a way that each cable drum 23, 24 exhibits a reducing width in a direction away from its respective sides 23A, 24A and 23B, 24B, towards its central area 23C, 24C, in which central area 23C, 24C, which is situated at a distance from said sides 23A, 23B; 24A, 24B, the width once more increases.
• Said cable drum arrangement enables the torque to remain constant for the whole of the period during which the door leaf 3 is actuated in such a way as to open, for example.
• the power requirement varies, in actual fact, depending on the length and form of the guide groove 5.
• the balancing spring arrangement 21 influences the door leaf 3 in a previously disclosed fashion, so that the power requirement also does not have to be so great.
• the door leaf 3 can also be made to be driven indirectly, for example in the case of door with a large height, via the spring-rotating shaft 22 by means of a door mechanism or hand winch. In this case the movement of the door leaf in both directions should be capable of being regulated, variations in the door cables 25 should be capable of being absorbed, and adjustment of their effective length should be capable of being made.
• each cable 25 may be passed around guide pulleys 28, 29 before the cable 25 arrives at the appropriate cable drum 23, 24, in conjunction with which one of the guide pulleys 28, or some other suitable direction-changing device, can be supported by a sprung arm 30, as shown in Fig. 16, for example.
• a stop 31 Shown in said Fig. 16 is a stop 31 which can also operate with a spring effect in such a way as to damp the movement of the door leaf by interacting with a shock-absorber stop 31A on the door leaf.
• Groove attachment sections 5A and 5B projecting from the door cassette 10 are so arranged as to be attached by means of the connecting device 32 to each of the fixed, straight grooves 4 which extend along the path of movement of the door.
• So-called transport rollers 33 and 34 or similar guide devices which are capable of moving along said guide groove 4, and a transport track 35 capable of being connected to the upper end 4A of each fixed groove 4, which track is so arranged as to be connected only occasionally to the guide groove 4, a re so arranged as to be capable of being accommodated by said groove 4 and rails 54 as the door cassette 10 is raised into position in the upper part of the opening.
• Each transport roller 33, 34 is connected to a holder 35, 36, which can be attached by means of counter-washers to the end walls 8, 9 via bolts 37, 38 capable of being accommodated in, for example, slot-shaped holes 39, 40 in the end walls 8, 9.
• each end wall 8, 9 and across the path of the door leaf on the outside 8B, 9B of each end wall 8, 9 is a connecting groove 41, 42, which is so adapted as to be capable of accommodating a lifting shackle 44 capable of being connected to a lifting cable 43 and is free to move along each groove 41, 42.
• Each of said lifting cables 43 is attached to its own telpher 55, which can be attached via fastening devices 45 in a detachable fashion to lower lifting brackets 46 capable of being connected to the grooves 4 in the two lower corners of the door opening for the purpose of lifting the door casette 10 to the area of its point of installation in the upper part 2A of the door opening.
• the lifting cables 43 are passed around upper guide rollers 47, which are supported by upper lifting brackets 48 attached in a detachable fashion to the door frame in the two upper side corners of the door opening.
• the door cassette 10 is appropriately lifted up synchronously by means of said two telphers 55 into its intended installation position I, as shown in Fig. 8.
• a check is made beforehand to ensure that the transport rollers 33, 34 are in alignment with the lower open part 4B of each guide groove 4, so as to be accommodated by said fixed guide grooves 4 during lifting.
• braces 49 projecting downwards from the cassette can be attached to the cassette 10, as shown in Fig. 17, so as to interact with said groove attachment devices 32 at the respective end walls 8, 9 of the cassette, or to some other suitable fixed attachment point.
• a screw device 50 which is so arranged as to act between said braces 49 and devices 32, etc., is so arranged upon actuation as to cause the deer cassette 10 and the groove 4 to move relatively towards one another, so that the grooves 4, 5 can be attached permanently to one another after the aforementioned transport tracks 35 have been removed.
• the transport rollers 33, 34 can be removed from the cassette 10.
• Said door cassette 10 is then attached to the door posts 51 of the door via self-tapping screws 52 introduced through appropriate openings 53 in the end walls 8, 9, whereupon the lower and upper lifting brackets 46, 48 can be removed.
• the upper part of the cassette 10 can exhibit an inclined upper part 10A, as may be appreciated clearly from Fig. 16.
• said inclined part 10A can be raised close to a ceiling and then moved away from the ceiling at the top outer end of the cassette 10 as the cassette is drawn in by means of the screw devices 50.
• the door leaf 3 With the door installed, the door leaf 3 will be guided by the guide rollers 7 along the grooves 4, 5.
• the door leaf 3 is capable, thanks to the present invention, of being packed tightly, as shown in Fig. 15, into a form similar to that of a roll, which occupies little space over both its height and its width.
• the door also exhibits safety devices (not shown here) which are intended to ensure the reliable function of the door even in the event of cable fracture, etc.
