Description

GUIDING MEMBER FOR A DOOR OPERATOR SYSTEM

TECHNICAL FIELD

The present invention relates to a guiding member for a door operator system. The guiding member is configured to facilitate guiding of a door of the door operator system when the door is moved between an open and closed position.

The present invention also relates to a guiding arrangement comprising such a guiding member.

The present invention also relates to a door operator system comprising such a guiding member.

BACKGROUND

In order to facilitate high speed closing of opening, door operator systems with doors being configured to be operated at high speed are provided. One of the most used principals to operate a rigid exterior high-speed door of a door operator system is a spiral door system. Such a door comprises a plurality of interconnected sections so as to allow change of direction of the door. Such a door may e.g. comprise a curtain made of a plurality of rigid slats that are connected by rigid hinges. The door curtain moves on both sides in vertical side tracks.

Over lintel the track change to a spiral contour so that the movement of the door changes from a vertical movement into a spiral movement. To open the door the door curtain is lifted or pulled on both sides upwards into the spiral track and downwards out of the spiral track into the closed position. The door operator system comprises a guiding arrangement comprising rollers arranged in connection to the hinges of the door sections, said rollers being configured to run in a U-tracks of said side tracks. By thus utilizing roller, low friction of the guiding arrangement is facilitated and thereby high-speed movement of the door.

The width of the inside U-track needs to be wider than the roller diameter too ensures that the rollers do not clamp. On the other hand, the gap between the U-track and the roller should not be too wide to reduce noise.

Such spiral-U-tracks are expensive to produce. Moreover, rollers are subjected to a lot of wear. Depending on if the roller touches one or the other of the inner U-track surfaces the roller turns right hand or left hand. If the door curtain shakes or works under changing pressure/wind direction the rollers switch, touching the surfaces of the U-track and have to abruptly change turning direction.

Once the door sections are moving in the overhead spiral track, the rollers run in the upper tracks on the inner U-track-surface and on the lower track on the outer U-track-surface, creating wear and noises. This means many rollers switch a few times their rotating direction. It is important that the rollers do run on a defined lane in the U-track and that the door sections are not allowed to move more than a few millimetres to right hand or left hand.

DE 20 2018 101 842 U1 discloses a guiding arrangement comprising a protruding spiral track and guide member comprising roller pairs, said guide members being arranged in connection to hinges between the door sections of the door, wherein the rollers of the respective roller pairs are configured to run on opposite sides of the protruding track in order to prevent changing the rotating direction of the rollers. Thus, utilizing pairs of rollers instead of single rollers increase costs, and the rollers may still be subjected to wear, and result in undesired noises. There is thus a need to provide a guiding member for a door operator system which may provide high speed door movement, which is cost-efficient, facilitates low noise operation, and low wear during guiding of the door.

OBJECT OF THE INVENTION

An object of the present invention is to provide a guiding member for a door of a door operator system, which guiding member facilitates high speed door movement, low noise during operation, low wear, and is cost-efficient.

Another object of the present invention is to provide a guiding arrangement comprising such a guiding member.

When said guiding member is guidingly engaged to a protruding track member, said sliding element is configured to slidingly engage with one of said opposite sides and said roller member is configured to rollingly engage with the other of said opposite sides of said protruding track member.

By providing such a guiding member with a sliding element and opposite roller member configured to guidingly engage with a single protruding track member, a guiding member, for a door operator system, with low friction and low wear is facilitated. Further, a guiding member, configured to guidingly engage with a single protruding track member, which is cost-efficient is facilitated. Further, a guiding member for a door operator system which, during door movement, facilitates low noise is provided. Further, a guiding member, for a door operator system, which facilitates high speed door movement is provided. By thus providing a guiding member with a combination of sliding element and roller member, a cost-efficient guiding arrangement including single protruding track members, with low friction and low wear during operation, i.e. during door movement.

Said first and second protruding track members and said first and second set of guiding members provides a guiding arrangement, wherein said guiding member is configured to be comprised in such a guiding arrangement, i.e. be comprised in said set of guiding members of such a guiding arrangement. According to an aspect of the present disclosure, the sliding element of the guiding member, when the guiding member is connected to a door and being guidingly engaged to a protruding track member, has a width having a main direction of extension corresponding to the longitudinal extension of the protruding track member. According to an aspect of the present disclosure, the guiding member, when connected to a door and being guidingly engaged to a protruding track member, has a length having a main direction of extension corresponding to the transversal extension of the door. According to an aspect of the present disclosure, the guiding member, when connected to a door and being slidingly engaged to a protruding track member, is configured to be arranged and transversely extend in its length direction between a door side of the door and a frame section. The guiding member according to the present disclosure is intended to guidingly engage with protruding track member having a protruding direction which is transversal, i.e. configured to extend in the transversal direction from a frame section towards the opening. According to an aspect of the present disclosure, for said guiding arrangement for which the guiding member is intended, said first protruding track member is configured to be arranged in connection to said first frame section at said first side so that it protrudes transversely towards said second frame section, and said second protruding track member is configured to be arranged in connection to said second frame section at said opposite second side so that it protrudes transversely towards said first frame section and hence said first protruding track member.

According to an embodiment of the guiding member, said sliding element has an inner side configured to face one of said opposite sides of said protruding track member, said inner side comprising at least one sliding surface configured to slidingly engage with that side of said opposite sides of said protruding track member. Hereby efficient sliding for efficient guiding along the protruding track member by means of said guiding member is facilitated, so as to facilitate efficient door movement.

According to an embodiment of the guiding member, said roller member is rotatably arranged about a roll axis, said roller member having a radial outer side configured to rollingly engage with one of said opposite sides of said protruding track member. Hereby efficient rolling for efficient guiding along the protruding track member by means of said guiding member is facilitated, so as to facilitate efficient door movement.

According to an embodiment of the guiding member, said guiding member has a connection configuration for facilitating connection of said guiding member to said door so that said sliding element, when said guiding member is connected to said door and guidingly engaged to said protruding track member, is allowed to pivot about a guide axis so as to facilitate guiding said door through a curved track of said protruding track member during door movement. According to an aspect of the present disclosure, said connection configuration has an axial extension corresponding to the guide axis. Hereby efficient guiding, by means of said guiding member being guidingly engaged to a protruding track member, both through guiding in connection to a straight track of said single protruding track member and in connection to a curved track of said single protruding track member, such as a spiral track, is facilitated.

According to an embodiment of the guiding member, the extension of said guide axis about which said sliding element is configured to be pivotable and the extension of said roll axis about which said roller member is rotatable are configured to be essentially parallel to the protruding direction of said protruding track member. Hereby efficient guiding, by means of said guiding member being guidingly engaged to a protruding track member, with low friction and low wear is facilitated. According to an embodiment of the guiding member, the closest distance between the inner side of said sliding element and said radial outer side of said roller member is greater than a thickness of said protruding track member. Hereby robust, easy and efficient guiding, by means of said guiding member comprising said sliding element, is facilitated both during straight, e.g. vertical guiding and during curved, e.g. spiral, guiding during door movement.

According to an embodiment of the guiding member, said at least one sliding surface of said sliding element and/or said radial outer side of said roller member has a convex configuration. Hereby the risk of clamping during door movement may be efficiently reduced. According to an aspect of the present disclosure, said at least one sliding surface of said sliding element has an arced shape, running in the length direction of said sliding element of said guiding member. According to an aspect of the present disclosure, said radial outer side of said roller member of said guiding member has an arced shape, running in the transversal direction, i.e. parallel to the length direction of said sliding element.

Hereby robust, easy and efficient guiding, by means of said guiding member comprising said sliding element, is facilitated both during straight, e.g. vertical guiding and during curved, e.g. spiral, guiding during door movement.

According to an embodiment of the guiding member, said inner side of said sliding element comprises a central recess arranged centrally relative to the width of said sliding element and extending in the main direction of extension of the length of the sliding element, said extension, when said guiding member is guidingly engaged to said protruding track member, corresponding to the protruding direction of said protruding track member, said central recess being configured to provide a distance to the side of said opposite sides of said protruding track member towards which said inner side is facing, which is greater than the distance between said sliding surface and said side of said opposite sides. Hereby the width of the sliding element of the guiding member, and hence the extension of the sliding element in the direction along the protruding track member, may be extended and still facilitate curved, e.g. spiral, guiding during door movement, thus facilitating a more stable guiding of said door. The longitudinal extension of said protruding track member is orthogonal to the protruding extension of said protruding track member.

According to an embodiment of the guiding member, said connection configuration of said guiding member is configured so that, when connected to said door, said guide axis has an extension essentially parallel to the main direction of extension of the length of said sliding element and centrally relative to the width of said sliding element. Hereby robust, easy and efficient guiding, by means of said guiding member comprising said sliding element and roller member, is facilitated both during straight, e.g. vertical guiding and during curved, e.g. spiral, guiding during door movement. Such a guiding member may be connected to the door in two ways, i.e. either so that the roller member rolls against the outer side, i.e. the side facing outwardly in the curved/spiral track of the protruding track member, and the sliding element slides against the opposite inner side of said protruding track member, or so that the roller member rolls against the inner side and the sliding element slides against the outer side of said protruding track member.

According to an embodiment of the guiding member, said connection configuration of said guiding member is configured so that, when connected to said door, said guide axis has an extension essentially parallel to the main direction of extension of the length of said sliding element and closer to one of the end sides of the sliding element relative to the width of said sliding element. Hereby robust, easy and efficient guiding, by means of said guiding member comprising said sliding element and roller member, is facilitated both during straight, e.g. vertical guiding and during curved, e.g. spiral, guiding during door movement. Hereby roller member and sliding element may be arranged so that the shortest distance between a sliding surface of said sliding element and the radial outer side of said roller member is smaller, which facilitate further reducing noises during door movement, i.e. when said guiding member is guidingly engaged to and moves along said protruding track member.

According to an embodiment of the guiding member, said guiding member, when connected to said door and guidingly engaged to said protruding track member, is configured so that said guide axis and said roll axis, configured to extend parallel the protruding direction of said protruding track member at a distance from each other, are extending so that an imaginary plane formed by the distance between said guide axis and roll axis is extending orthogonal relative to the main direction of extension of the width of said sliding element and orthogonal to the main direction of extension of the length of said sliding element. Hereby robust, easy and efficient guiding, by means of said guiding member comprising said sliding element and roller member, is facilitated both during straight, e.g. vertical guiding and during curved, e.g. spiral, guiding during door movement.

According to an embodiment of the guiding member, said connection configuration of said guiding member is configured so that said guide axis, when said guiding member is guidingly engaged to said protruding track member, is configured to extend essentially in line with the protruding direction of said protruding track member.

According to an embodiment of the guiding member, said connection configuration of said guiding member is configured so that, when said guiding member is configured to be connected to said door, said guide axis and said roll axis are coaxially arranged so that said sliding element and said roller member are rotatable about an axis having the same axial extension, wherein said sliding element and said roller member are arranged so that they are allowed to rotate relative to each other. Hereby robust, easy and efficient guiding, by means of said guiding member comprising said sliding element and roller member, is facilitated both during straight, e.g. vertical guiding and during curved, e.g. spiral, guiding during door movement. Hereby stiffer fixation of said roller member is facilitated.

According to an embodiment of the guiding member, said guiding member comprises a support member, configured to support said sliding element, wherein said support member is configured to be pivotably connected to said door about said guide axis for allowing pivoting of said sliding element about said guide axis. Hereby robust, easy and efficient guiding, by means of said guiding member comprising said sliding element and roller member, is facilitated both during straight, e.g. vertical guiding and during curved, e.g. spiral, guiding during door movement. Hereby a robust configuration for said sliding element is facilitated.

According to an embodiment of the guiding member, said support member comprises said connection configuration. Hereby a robust configuration with easy connection to said door for pivoting of said sliding element about said slide axis is facilitated.

With reference to fig. 8, said guiding member parts G1 , G2 may comprise a first guiding member part G1 comprising said first support portion 232 and said sliding element 210 supported by said first support portion 232, and a second guiding member part G2 comprising said second support portion 234 and said roller member 220 supported by said second support portion 234. The guiding member parts may be configured to be connected to each other by means of one or more joint members, e.g. screw members. The guiding member 200 described in e.g. fig. 9-13 may also be made of two guiding member parts. By thus providing a guiding member 200 made of two guiding parts as described, facilitates manufacturing and assembling of said guiding member 200.

According to an aspect of the present disclosure, as shown in fig. 5 and 6, said support member 230, not shown in fig. 5 and 6, and said sliding element 210 supported by said support member, constitute a first unit U1 , and said roller member 220 constitute a second unit U2 separate from said first unit.

According to an aspect of the present disclosure, as shown in fig. 5 and 6, said guiding member 200, when attached to said door 20, is configured so that said first unit U1 is configured to be pivotably connected to said door 20 about said guide axis X2 by means of said connection configuration C200, not shown in fig. 5 and 6. According to an aspect of the present disclosure, as shown in fig. 5 and 6, said guiding member 200, when attached to said door 20, is configured so that said first unit U1 is configured to be pivotably connected to said door 20 about said guide axis X2 by means of said connection configuration C200 comprised in said support member 230.

Further, according to an aspect of the present disclosure, as shown in fig. 5 and 6, said guide axis X2, when said guiding member 200 is guidingly engaged to said protruding track member 100, has an extension essentially parallel to the main direction of extension of the length of said sliding element 210, i.e. the protruding direction of said protruding track member 100, and centrally relative to the width W1 of said sliding element 210. Further, according to an aspect of the present disclosure, as shown in fig. 5 and 6, said guide axis X2, when said guiding member 200 is guidingly engaged to said protruding track member 100, is configured to extend essentially in line with the protruding direction of said protruding track member 100. Further, according to an aspect of the present disclosure, as shown in fig. 5 and 6, said second unit U2, i.e. said roller member 220 is configured to be connected to said door 20, e.g. via a hinge member 50, about said roll axis X3. According to an aspect said roller member 220 is configured to be fixedly connected to said door 20, e.g. fixedly connected to said hinge member 50, by means of a shaft so that said wheel 222 of said roller member 220 is allowed to rotate relative to said shaft about said roll axis X3.

Said second unit U2, i.e. said roller member 220, is here independent of said first unit U1 , i.e. said support member and sliding element 210 supported by said support member, so that, when said sliding member 200 is thus connected to said door 20, and said sliding element and hence the support member supporting said sliding element 210 is rotating about said slide axis X2, said roller member 220 is not affected by that rotation. Thus, the roll axis X3 is not rotatable about said slide axis X2. The roller member 220, being fixedly connected to said door 20, e.g. via said hinge member 50, is arranged so that it is roll ingly engaged with the outer side 21 Oo, of said protruding track member 100 so that it rotates about said roll axis X3 during door movement, independently of pivoting of said sliding element 210 about said slide axis X2.

By thus having said roller member 220 as a separate second unit U2 directly connected to said door 20, e.g. via a hinge member 50, and not connected to said door 20 via the support member of said guiding member 200, the difference D3 between the closest distance D2 between the inner side 21 Oi of said sliding element 210 and said radial outer side 220a of said roller member 200 and the thickness D1 of said protruding track member 100 may be reduced and still facilitate efficient guiding in the spiral track 120 of said protruding track member 100. The difference D3 is in fig. 5 and 6 illustrated as the gap between the outer side 100o of the protruding track member 100 and the radial outer side 220a of the roller member 220 when the inner side 21 Oi of said sliding element touches the inner side 10Oi of said protruding track member 100. The closest distance D2 between the inner side 21 Oi of said sliding element 210 and said radial outer side 220a of said roller member 200, refers to the distance when said inner side 21 Oi of said sliding element 210 touches the inner side 100i of said protruding track member 100. Said difference D3 corresponds to the distance D3 between said radial outer side 220a of said roller member 220 and the outer side 100o of said protruding track member 100.

By thus having said roller member 220, i.e. second unit U2, as a separate second unit U2 directly connected to said door 20, e.g. via a hinge member 50, and not connected to said door 20 via the support member of said guiding member 200, and having the first unit U1 , i.e. the support member with the sliding element 210, separately connected to said door 20, e.g. via said hinge member 50, the distance D2 increases when the guiding member 200 thus connected to the door 20, during door movement from a closed to an open position, transfers from a guiding engagement with the straight track 110 of the protruding track member 100, as illustrated in fig. 5, to a guiding engagement with the spiral track 120, as illustrated in fig. 6. This is due to said connection of the guiding member 200 to the door 20, and due to the pivoting of said adjacent door sections 22, increasing the angle between said opposite long sides of said adjacent door section 22. Said distance D2 will hereby increase with decreased radius of the spiral track 120 during movement along the spiral track 120 of the protruding track member 100.

According to an aspect of the present disclosure, as shown in fig. 5 and 6, said guide axis X2 and said roll axis X3, configured to extend parallel the protruding direction of said protruding track member 100 at a distance from each other, are extending so that an imaginary plane P1 , formed by the distance between said guide axis X2 and roll axis X3 and the extension of said guide axis X2 and roll axis X3, is extending in an angle relative to an imaginary plane formed by the main direction of extension of the length of said sliding element 210 and the direction of extension orthogonal to the main direction of extension of the width W1 and the main direction of extension of the length of said sliding element 210. Thus, said plane P1 is extending in an angle relative to an imaginary plane formed by the protruding extension of the protruding track member 100 and the direction of extension orthogonal to the protruding extension of the protruding track member 100 and the longitudinal extension of the protruding track member 100.

According to an aspect of the present disclosure, as shown in fig. 5, there is a distance D6 between a long side 22c of one door section 22, here the lower door section 22, and the long side 22d of an adjacent door section 22, here an upper door section 22 in the vertical direction relative to the lower door section 22.

According to an aspect of the present disclosure, as shown in fig. 5, said slide axis X2 is arranged centrally between said adjacent door sections 22 so that an imaginary plane P2, formed by the extension of said slide axis X2 and the direction of extension orthogonal to the extension of said slide axis X2 and orthogonal to the longitudinal extension of the protruding track member 100, and hence orthogonal to the width W1 of said sliding element 210, is running centrally between and along said said long side 22c of the lower door section 22 and the long side 22d of the adjacent upper door section 22.

According to an aspect of the present disclosure, as shown in fig. 5, said roll axis X3 is arranged displaced between said adjacent door sections 22 so that an imaginary plane P3, formed by the extension of said roll axis X3 and the direction of extension orthogonal to the extension of said roll axis X3 and orthogonal to the longitudinal extension of the protruding track member 100, and hence orthogonal to the width W1 of said sliding element 210, is running displaced relative to said adjacent door sections 22, here along a portion of the upper door section along in the direction of extension of the long side of upper door section 22.

Hereby said imaginary plane P2 and said imaginary plane P3 are at a distance B from each other, said distance being associated with the displacement of said slide axis X2 relative to said roll axis X3.

According to an aspect of the present disclosure, as illustrated in e.g. fig. 8-13, said guiding member 200 has a connection configuration C200 for facilitating connection of said guiding member 200 to said door 20 so that said sliding element 210, when said guiding member 200 is connected to said door 20 and guidingly engaged to said protruding track member 100, is allowed to pivot about a guide axis X2 so as to facilitate guiding said door through a curved track 120 of said protruding track member 100 during door movement.
