Description

A DOOR OPERATOR SYSTEM

TECHNICAL FIELD

The present invention relates to a door operator system.

BACKGROUND

A door operator system for an overhead door typically comprises a door connected to a door frame and a drive unit arranged to move the door along the door frame between an open and closed position for opening and closing the opening. The door, which may be a sectional door, is typically used as a garage door or as an industrial door. The drive unit can further comprise a motor to move the door.

In conventional overhead sectional door an electric motor mounted above the door pulls up the door using wires attached to the door. Such an overhead sectional door often implements balancing springs to reduce the force required to open the door, which increases complexity and is cumbersome to install. Should there be a damage such as a broken wire on such a conventional overhead sectional door, mechanical devices are used to stop the door from falling.

To achieve a more efficient door operator system that reduces the complexity and the risks of the door operator system during operation, maintenance and installation, a door operator system with drive units mounted to the door so that they move with the door when the door is moved between the open and closed position has been developed. The door is moved by means of the drive units, the drive units comprising motors and driven transmission members configured to interplay with elongated transmission members, e.g. chains, extending on the respective side of the door. The drive units are powered by power units fixedly arranged on the respective side of the door, the respective power unit being connected to the respective drive unit by means of spiral cable device arranged externally relative to the frame section along which the door and hence the drive unit is moving in connection to opening and closing operation of the door. The external spiral cable device facilitates movement of the cable in connection to movement of the drive unit relative the power unit. However, such a spiral cable device may disturb the emergency stop of the door operator system. Further, such a spiral cable device needs to be exchanged when new functionality is to be added.

There is thus a need for a chain a door operator system with a cable device which facilitates door operation and maintenance in a safe and efficient way.

Fig. 1 schematically illustrates a perspective view and fig. 2 and 3 a front view of a door operator system S in which the inventive aspects of the present invention may be applied. The door operator system comprises a door frame 10, a drive arrangement D and a door 20. The door operator system S is arranged to be installed in an opening 0 defined by a wall and a floor/ground. The door 20 is connected to the door frame 10. The door operator system S is arranged to open and close the opening 0 by moving the door 20 between an open position P1 and a closed position P2. The door 20 is in the closed position P2 in fig. 1 and in the open position P1 in fig. 2. The open position may be a horizontal open position, which the door operator system in fig. 1 schematically illustrates, in the form of a planar horizontal position or an inclined horizontal position such as a vertical open position as illustrated in fig. 2. The closed position P2 may be a vertical closed position P2.

In the embodiment illustrated in e.g. fig. 1 , the door 20 is a sectional door 20 comprising a plurality of horizontal and interconnected sections 20a-e connected to the door frame 10. In one embodiment, the door is a garage door. In an alternative embodiment, the door is an industrial door. The door 20 is arranged to be moved along the door frame 10 between the closed position P2 and the open position P1 .

The door operator system schematically illustrated in fig. 1 is an up and over door operator system. An up and over door operator system is a system in which the door in the closed position P2 is arranged substantially vertical and in the open position P1 is arranged substantially horizontal and inside of the opening.

In an alternative embodiment, the door operator system may be a door operator system in which the door in the closed position P2 is arranged substantially vertical and in the open position P1 is arranged in an inclined position disposed between a substantially vertical and a substantially horizontal position. For example, the door may be arranged at a 45 ° angle from a horizontal position P1 in the open position P1 , as the skilled person recognizes however the door may be arranged at any angle disposed between the horizontal and vertical orientation of the door in the open position P1. The door may be arranged at an essentially vertical orientation in the open position P1 as illustrated in fig. 3.

The door frame 10 comprises a first frame section 12 at a first side I of the opening O and a second frame section 14 at a second side II of the opening O. The door frame 10 is connected to the wall and to the floor, i.e. the floor of the opening O. In one embodiment, illustrated in fig. 1 , the first frame section 12 comprises a substantially vertically extending part 12-1 and a substantially horizontally extending part 12-2. The second frame section 14 comprises a substantially vertically extending part 14-1 and a substantially horizontally extending part 14-2. The vertically extending part 12-1 , 14-1 and the horizontally extending part 12-2, 14-2 are connected to create a path for the door 20 to glide on and a track for the drive unit 30 to interact with.

Thus, each of the first frame section 12 and the second frame section 14 comprising a vertically extending part 12-1 , 14-1 , a horizontally extending part 12-2, 14-2 and a bent interconnecting part 12-3, 14-3. Worded differently, The first frame section 12 comprises a vertically extending part 12-1 , a horizontally extending part 12-2 and a bent interconnecting part 12-3. The bent interconnecting part 12-3 thus connects the vertically extending part 12-1 and the horizontally extending part 12-2 .Similarly, the second frame section 14 comprises a vertically extending part 14-1 , a horizontally extending part 14-2 and a bent interconnecting part 14-3. The bent interconnecting part 14-3 thus connects the vertically extending part 14-1 and the horizontally extending part 14-2.

The vertically extending parts 12-1 , 14-1 may be vertical parts 12-1 , 14-1 or inclined vertical parts 12-1 , 14-1 . Similarly, the horizontally extending parts 12- 2, 14-2 may horizontal parts 12-2, 14-2 or inclined horizontal parts 12-2, 14-2.

The door 20 is at a first side I moveably connected to the first frame section 12 and at a second side II moveably connected to the second frame section 14. In one embodiment, one or more of the plurality of sections 20a-e is connected to the first frame section 12 at said first side I and to the second frame section 14 at said second side II.

According to an aspect of the present disclosure, as illustrated e.g. in fig. 1 -3, said first frame section 12 has a first side 12a facing away from the opening O and an opposite second side 12b facing towards said opening O. According to an aspect of the present disclosure, as illustrated e.g. in fig. 1 -3, said second frame section 14 has a first side 14a facing away from the opening 0 and an opposite second side 12b facing towards said opening 0. The door operator system S comprises said drive arrangement D for operation of said door operator system. Said drive arrangement D comprises a drive unit 30 mounted on the door 20. Said drive unit 30 is arranged to move the door 20 between the closed position P2 and open position P1 . Said drive unit 30 is configured to be mounted on the door 20 so that it moves with the door when the door is moved between the open and closed position.

Said door operator system S further comprises an operation unit 100. Said operation unit 100 is configured to be fixedly arranged relative to the door 20 in connection to the first side I. Said operation unit 100 is according to an aspect of the present disclosure configured to be fixedly arranged at level between the lower level and upper level of said opening O in connection to said first side I.

Said door operator system S further comprises a cable arrangement 50 configured to be operably connected between the drive unit 30 and the operation unit 100. The fact that the drive unit 30 is connected to the door 20 and configured to move with the door when the door 20 is moved between the closed position P2 and open position P1 and the fact the said cable arrangement 50 at one end is operably connected to said thus movable drive unit 30 and at another end to said fixed operation unit 100, results in movement of the cable arrangement 50 in connection to door movement.

According to an aspect of the present disclosure, as schematically illustrated in fig. 1 -3, said first frame section 12 comprises a through hole 01 at said first side 12a, said through hole 01 being arranged to run through the first side 12a, wherein said cable arrangement is connected to said operation unit 100 via said through hole 01 .

Said cable arrangement 50 is described in more detail below, with reference to fig. 1 -3 and also fig. 5a-b and fig. 6a-c. Said drive unit 30 comprises at least one motor 32. Said at least one motor 32 is arranged to move the door 20 between the closed position P2 and open position P1 .

To allow for the driving of the door 20, the door operator system S further comprises an elongated transmission member 40 as schematically illustrated in fig. 1 , extending along the first side I of the opening 0. The elongated transmission member 40 may further extend along the first frame section 12. The drive unit 30 further comprises a driven transmission member 34 which is in driving connection with the motor 32.

The driven transmission member 34 is movably connected to the elongated transmission member 40 and arranged to interplay with said elongated transmission member 40 for driving the driven transmission member 34 along said elongated transmission member 40 by means of the elongated transmission member 40 at least partially wrapping around the driven transmission member 34. Thus, the elongated transmission member 40 is arranged to at least partially envelope said driven transmission member 34.

The elongated transmission member 40 does in comparison with a fixed rack provide a more cost-efficient solution both in terms of manufacturing and installation. Furthermore, the elongated transmission member allows for relative movement between the door 20 and the frame and does not require a high accuracy and proper aligning in the same manner as a fixed rack solution. The elongated transmission member may thus be arranged to allow for a degree of movement along a direction orthogonal to the first frame section 12.

Further, the elongated transmission member 40 enables a safer door operator system due to said elongated transmission member following and keeping the engagement with the driven transmission member, at least to some extent, even if the door is pushed away from the rail. In addition, the elongated transmission member is more silent and resistant to wear compared to a fix rack and less likely to malfunction due to pinching of external objects. The elongated transmission member 40 may be in the form of a bendable transmission member. The elongated transmission member 40 may be in the form of a suspended transmission member. It is noted that bendable in this context does not necessarily imply that said transmission member necessarily is flexible but only that it allows for wrapping around the driven transmission member. Accordingly, the transmission member 40 may be considered to be arranged to be in engagement with the driven transmission member 34 and provide for relative movement between the driven transmission member 34 and a direction of movement of the door 20 as defined by the frame 10. Worded differently said transmission member may be considered as a non-fix transmission member or a suspended transmission member. The elongated transmission member may accordingly be arranged to engage the driven transmission member independently of the frame.

The drive unit 30 is moveably connected to the elongated transmission member 40. Accordingly, drive unit 30 is connected to said elongated transmission member 40 so as to allow for relative movement between the door and the frame, whereby the drive unit 30 is fixed to the door 20. The drive unit 30 comprises at least one motor 32. The drive unit 30 is arranged to move the door 20 from the closed position to the open position. To provide power to the motor 32, the at least one motor 32 may be connected to at least one energy storage device, such as a battery, arranged to power the at least one motor 32.

In one embodiment, the drive unit 30 is arranged to move the door from the open position P1 to the closed position P2. In one embodiment, the door 20 is arranged to move from the open position P1 to the closed position P2 by means of the weight of the door 20. In one embodiment, the drive unit 30 is arranged to brake the door 20 when moving from the open position P1 to the closed position P2.

The elongated transmission member 40 may be biased. The biasing of the elongated transmission member 40 enables keeping of the tension of the resilient elongated member 40 at a suitable level and further compensates for wear and potential tolerance issues.

In one embodiment, the elongated transmission member 40 may be biased by means of a spring arrangement. A top end of the elongated transmission member 40 may be fixedly mounted and a bottom end of said elongated transmission member 40 may be spring-loaded. This allows for easier access for an operator performing service work involving the spring. In one embodiment, the top and bottom end of the elongated transmission member 40 is mounted to the frame, for example the first frame section 4.

Fig. 4 schematically illustrates a perspective view of a part of a door operator system with a drive unit 30 according to an aspect of the present disclosure.

In one embodiment, as illustrated in fig. 4, the door operator system further comprises at least one guide member R1 . The at least one guide member R1 is mounted to the door 20. The guide member R1 may be arranged to interplay with the elongated transmission member 40 for guiding the door 20 along the elongated transmission member 40 by means of the elongated transmission member 40 at least partially wrapping around the at least one guide member R1 . The guide member R1 thus moves the elongated transmission member 40 and guides the driven transmission member 34 in relation to said elongated transmission member 40 to properly align them. The guide member R1 may preferably be a rotatable guide member which may be mounted to the door 20 by means of a journaled connection. Thus, the elongated transmission member 40 may be arranged to at least partially envelope said guide member R1.

With reference to fig. 4, the elongated transmission member 40 may be arranged to wrap around and interplay with a portion of the driven transmission member 34 and a portion of the guide member R1. The portion of the driven transmission member 34 interplaying with the elongated transmission member 40 being opposite to the portion of the guide member R1 interplaying with said elongated transmission member 40. This achieves a larger interface between the driven transmission member, guide member and elongated transmission member, whereby a more stable door operator system which requires less torque to operate may be achieved.

In fig. 4, and end portion 54b of a cable device of said cable arrangement 50 is shown, connected to the drive unit 30.

The elongated transmission member 40 may be any conventional elongated transmission member 40 providing the required slack to compensate for horizontal or diagonal movement of the drive unit and/or door. The elongated transmission member may be a belt or a chain.

In one embodiment, the elongated transmission member 40 may be a belt. Thus, the guide member R1 and the driven transmission member 34 may be pulley elements arranged to interface with said belt. In one embodiment, the belt may be a cogged belt or a ribbed belt, whereby the guide member R1 and the driven transmission member 34 may be cogged wheels interfacing with the ribs of said cogged or ribbed belt.

The elongated transmission member 40 may also be a chain, which is depicted in fig. 4. The chain may be provided with slots for receiving cogs. Accordingly, the driven transmission member 34 may be a cogged wheel arranged to interplay with the chain, e.g. the slots of the chain. The driven transmission member 34 may be a sprocket. Further, the guide member R1 may be a cogged wheel arranged to interplay with the chain, e.g. the slots of the chain. The guide member R1 may be a sprocket. In one embodiment, the guide member R1 may be a ribbed wheel for interplaying with the chain. In one embodiment, the chain is a non-endless chain, e.g. a single chain only partially enveloping the guide member(s) and the driven transmission member(s).

In one embodiment, the door operator system further comprises a first set of guide rollers R2 and a second set of guide rollers R2, see e.g. fig. 2 and 3. The driven transmission member 34 and the elongated transmission member 40 have been left out from fig. 2 and 3 for facilitating illustrating said cable arrangement 50. Said first and second set of guide rollers are mounted to the door 20. The first set of guide rollers R2 are arranged to interplay with the first frame section 12 and the second set of guide rollers R2 are arranged to interplay with the second frame section 14. The guide rollers thus moves together with the door 20 in a guided manner along the trajectory formed by the frame, e.g. the first frame section 12 and the second frame section 14.

In one embodiment, the drive unit 30 is mounted to the bottommost section 20e of the door 20.

The guide roller R2 is according to an aspect mounted to the door 20 by means of a shaft R2s.

According to an aspect of the present disclosure, as schematically illustrated in fig. 1 , 2 and 3, the door operator system comprises a pair of elongated transmission members 40 to allow for a more stable movement pattern of the door 20. A first elongated transmission member 40 extends along the first side I of the opening O. The first elongated transmission member 40 may further extend along the first frame section 12.
