Definitions

  • the invention relates to a turning device in connection with a lift door comprising several horizontal lamellas hinged together on top of each other, and track wheels arranged at outermost hinges of the lamellas and at the lower edge of the door designated to move along a track arranged on both sides of the door, each track comprising a vertical part attached to a vertical part of a frame of the door, a horizontal part located substantially at a height of the upper edge of the door, and a curved part connecting the vertical and horizontal parts.
  • Such doors are commonly used as garage doors.
  • a common problem with the laminated lift doors has been the large additional vertical space needed in addition to the height of a door to enable the uppermost lamella to turn in a normal operating situation.
  • lowering kits whose operation is based on double tracks are available but they must be separately ordered.
  • a common feature of these lowering kits is that they are expensive while the necessary additional space still remains large. All this makes the laminated doors more difficult to sell compared to other door types, particularly when many garages have a problematically low ceiling.
  • Fl 91986 discloses a turning device comprising a lever arm element attached to a door and arranged with a bearing in connection with a hinge between two uppermost lamellas coaxially with a track wheel located at the same point, and a mechanical control element immovably arranged in connection with a vertical part of a door frame or a track and arranged to be connected over a predetermined distance with the lever arm element when being close to the beginning of an opening position and the end of a closing position of the door, and a force arm connected between the lever arm element and a fixing arm of the uppermost track wheel, whereby when the door is opened, the mechanical control element turns the lever arm element which, in turn, via the force arm, forces the uppermost track wheel and the uppermost lamella closer to each other, thus causing the uppermost lamella to turn.
  • the lever arm element comprises a toothed wheel and a lever arm unturnably attached in connection with the same, an end of the lever arm being pivotally mounted at the lower end of the
  • the operating principle of the structure described above is the mechanical control of the upper lamella implemented by the uppermost track wheel and forced by the relative movement of the door and the frame structure at the beginning of the lifting movement and at the end of the closing movement of the door.
  • the turning device forces the upper lamella to turn as soon as the lifting movement has started, and when the door is closed, to take the same path as when the door was opened, now only in a reverse direction.
  • An object of the present invention is to improve the prior art turning device based on the above-described mechanical control.
  • the object is achieved by a mechanical control device of the invention, which is characterized in that the turning device to be arranged at least on one side of the door comprises:
  • the turning device of the invention is an entirely independent device which is easy to attach by its frame to the edge of the lamella.
  • the device is also safe since the toothed wheel/mechanical control system is located high up in connection with the horizontal section of the track, which means that it is not dangerous for the user. Furthermore, the device is less expensive and lighter to use.
  • Figure 1 shows a laminated lift door comprising four horizontal lamellas 1 on top of each other and hinged together by hinges 2, and track wheels 3 arranged in connection with outermost hinges 2 of the lamellas 1 and close to the lower edge of the door on the same vertical planes as track wheels 3 located at the outermost hinges 2.
  • the door also comprises uppermost track wheels 3a but they are parts of turning devices to be described below, wherein the door will not be provided with the uppermost track wheels 3a controlling the turning of the upper lamella 1 until in connection with the installation of the turning devices.
  • the track wheels 3 are designated to move along a track 4 provided on both sides of the door, each track comprising a vertical part 4a attached to a vertical part 5 of a door frame or the like, a horizontal part 4b located substantially at a height of an upper edge of the door and attached to a ceiling of a garage or the like, and a curved part connecting the vertical and horizontal parts 4a and 4b.
  • the turning device comprises a vertical frame 5 to be attached to the edge of the uppermost lamella; an articulated arm 6 comprising two articulated arm parts 8 and 9 pivotally mounted to each other by a folding joint 7 such that the parts 8 and 9 are allowed to fold around the joint 7 in one direction towards each other, a first articulated arm part 8 being pivotally mounted to the frame 5 by a first frame joint 10; a turning arm 11 whose one end is pivotally mounted by a second frame joint 12 at a distance in the frame 5 underneath the pivoted mounting point (the frame joint 10) of the first articulated arm part while a second end is pivotally mounted in the same axle 19 as a second articulated arm part 9, rotatably with respect to the second articulated arm part 9; a toothed wheel element 13 unturnably attached with respect to the second articulated arm part 9 but turnably attached with respect to the turning arm 11; an uppermost track wheel 3a designated to move along a track 4 and attached to the same axle as the toothed wheel element 13; and a mechanical control element 14 attached to
  • the frame 5 is provided with strengthening fastener lugs 5a to be arranged in an edge of the lamella 1, which is often slack.
  • the frame 5 is bolted both to the edge and on top of the lamella 1, the structure becomes sturdy and the installation distance of the device is right in a lateral direction of the lamella 1.
  • both articulated arm parts 8 and 9 can be adjusted.
  • the parts 8 and 9 comprise two telescopically adjustable parts 8a, 8b and 9a, 9b which can at any given time be immovably locked with respect to each other by screws 15 and 16.
  • the inner parts 8b and 9b are provided with designations 8c and 9c.
  • each articulated arm part 8 and 9 should be subjected to equal adjustments in order for the lever relations not to change. This possibility to adjust is necessary since the distances between the lamella 1 and the track 4 may slightly change.
  • An outermost tooth 13a of the track wheel element 13 is elongated to enable interaction with the mechanical control element 14 to start smoothly as soon as the door is being closed.
  • the outermost tooth 13a also interacts with a locking device 17, which will be described in the following in connection with Figures 7 and 8 and which, when the door is opened, locks the turning device into a particular position with respect to the upper lamella 1 and, when the door is closed, releases the turning device from the locking.
  • a locking and releasing lever 18 of the locking device 17 is arranged close to the elongated tooth 13a which is arranged in the same axle 19 as the turning arm 11, articulated arm part 9, toothed wheel element 13 and the uppermost track wheel 3a.
  • the lever 18 comprises a fixing sleeve 18a to be arranged around the axle 19 whereby the lever 18 is attached to the axle 19 by a fixing pin 20.
  • the fixing sleeve 18a is provided with transverse openings 18b such that the lever 18 is allowed to turn a restricted distance around the axle 19.
  • the lever 18 is also stretched into an extreme position at the front of the elongated tooth 13a by a string 21 arranged between the lever 18 and the toothed wheel element 13, which means that a clutch 18c in the sleeve is against a locking pin 22 fixedly arranged in the frame 5.
  • a string 21 arranged between the lever 18 and the toothed wheel element 13, which means that a clutch 18c in the sleeve is against a locking pin 22 fixedly arranged in the frame 5.
  • the turning device locks, preventing the upper lamella 1 from moving with respect to the turning device.
  • the locking of the upper lamella 1 is important in a door equipped e.g. with an opener (not shown in the drawings) since the operating arm of the opener uses the door by pulling and pushing the upper lamella 1. If the door is opened with vigour, the door may start bouncing and the lamellas 1 may come into contact with the ceiling if there is little space above the horizontal section 4b of the track 4.
  • the mechanical control element 14 shown in Figures 9 and 10 comprises a "chainlike" part 14a curved in a similar manner to that of the curved section 4c of the track 4 and provided with transverse pins 14c located at a distance from each other and designated to interact with the teeth of the toothed wheel element 13.
  • the part 14a is attached to a side of the track section 4c by a frame part 14d fixedly connected thereto.
  • the part 14 d is provided with elongated mounting holes 14e to enable the part 14d to be mounted adjustably.
  • the frame part 14d comprises spikes 14f to determine the correct vertical position of the mechanical control element 14 when they are pressed into the track section 4c.
  • the operation of the turning device is shown step by step in Figures 11a to 11c.
  • the mechanical control device 14 forces the toothed wheel element 13 to turn around its axle 19. Since the articulated arm part 9 is unturnably attached to the same axle, the articulated arm parts 8 and 9 also start folding with respect to each other, in which case the uppermost track wheel 3a and the upper lamella 1 also start to draw closer to each other, i.e. the upper lamella 1 turns.
  • the door is closed, which means that the articulated arm parts 8 and 9 are in a horizontal position and the track wheel element 13 comes into contact with the foremost part of the mechanical control element 14.
