Technical field

The present invention relates to a module for transferring rotational motion to an openable and closable element, such as a door leaf, and a system comprising a module.

Background

In order to automate or otherwise assist with operation of openable and closable elements, such as door leaves or gates, actuators are used. Normally, the actuator is an opener or a closer, i.e. it is either adapted to apply power in order to move an element from a default position, such as a closed position, or apply power and/or release power in order to move an element to a default position. An actuator referred to as an opener is commonly designed to move a door leaf from and to a closed position and is hence commonly designed to open and close a door leaf. When used for opening and/or closing a door leaf, the actuator is often placed above the door leaf.

Among existing prior art solutions, US 5680674, NL 54742, DE 297503, GB 1207843 and EP 2900890 may be mentioned.

A common problem when designing such a system is that the desired torque varies with the opening angle of e.g. the door leaf. It may, for example, be necessary for a door leaf closer to apply a large torque for small opening angles in order to properly move the door leaf into a latched position. Vice versa, it may be necessary for a door leaf opener to apply a higher torque at small opening angles in order to move the door leaf from such a latched position. Although there exist some solutions aimed at this problem, they are often bulky, sensitive to damage and sabotage, not protected from weather and fouling, and aesthetically unpleasing. As such, there is a need for a module for transferring rotational motion which exhibits.

Summary

An object of the present invention is therefore to overcome the above problems, and to provide a solution that at least to some extent improve upon the prior art. This, and other objects, which will become apparent in the following, is accomplished by the module for transferring rotational motion to an openable and closable element defined in the accompanying claims.

Another object is to provide such a module which is compact.

Another object is to provide such a module which is protected from weather and fouling.

Another object is to provide such a module which is less time consuming to install.

Another object is to provide such a module which is less exposed to outside access, such that it is not easily damaged or sabotaged.

In a first aspect of the present invention, a module for transferring rotational motion to an openable and closable element, such as a door leaf, is provided, the module being configured to be mechanically connected to an actuator, the module comprising: a profile element housing; a link arm system at least partially arranged in the profile element housing, the link arm system comprising a first link arm, a second link arm, wherein the second link arm, at a first end portion thereof, is rotatably connected to a first end portion of the first link arm, and a third link arm configured to be mechanically connected to the actuator, wherein the third link arm is rotatably connected to a second end portion of the second link arm by means of a link arm pin around which the second link arm is configured to rotate such that motion of the third link arm is translated to a composite rotational and linear motion of the second link arm, wherein the link arm pin is provided with least one sliding element configured to slide along a straight interior track of the profile element housing, the straight interior track being defined by at least one inner surface of the profile element housing and configured to guide the at least one sliding element and the associated second end portion of the second link arm along a linear path; a rotation pin pivotably hinged to the profile element housing about an axis of rotation, the rotation pin being at least partially arranged within the profile element housing and, wherein an end portion of the rotation pin is accessible from an outside of the profile element housing and configured to be mechanically connected to the openable and closable element, wherein the rotation pin is attached to a second end portion of the first link arm in a torsionally fixed manner; and wherein the link arm system is configured such that motion of the third link arm rotatably connected to the second end portion of the second link arm, via the first link arm and the second link arm, is translated to rotational motion of the rotation pin, thereby enabling a rotation of an associated openable and closable element.

An openable and closable element is to be understood as an element which comprises a principal axis of rotation and which participates in directing flow, allowing passage of a thing or a person etc. For example, an openable and closable element may be, but is not limited to, a door leaf, a window, a gate or a bar.

A composite rotational and linear motion is to be understood as a motion that has both a rotational and linear component. As such, when the third link arm moves, e.g. through a linear motion, the second link arm will move in both a rotational and linear fashion. Hereby, the distance over which the third link arm may perform work on the second link arm, and this the first link arm and the rotation pin, is increased.

A sliding element may e.g. be a sliding block. A sliding block may e.g. have a shape complementary to the interior track. A sliding block may further be made of a low friction material, or may comprise a layer of low friction material such that the layer of low friction material is arranged against the interior track.

A sliding element may alternatively be a wheel. A sliding element may alternatively include a pair of wheels. The wheels may be arranged on a common axis. The link arm pin may act as a common axis for the wheels. The wheels may hence be arranged on opposite sides of the third link arm on the rotation pin.

Due to the fact that the link arm system being at least partially arranged within a profile element housing, a module according to the first aspect of the present invention is compact and protected against weather and fouling. The module is further configured to directly transfer rotational motion through a rotation pin to an openable and closable element, and is thus easy to install in relation to the openable and closable element.

Further, the straight interior track being defined by at least one inner surface of the profile element housing entails that a more compact solution is provided. Furthermore, the fact that the interior track is straight generally result in a design which is less prone to undesired wear of the sliding element provided on the link arm pin as well as of the interior track since the sliding element is subjected to motion which naturally follows the straight extension of the interior track. Hence, a more robust and long-lived module may be provided.

The first link arm and the second link arm may have different lengths. Alternatively, the first link arm and the second link arm may have substantially the same length. The first link arm and the second link arm are preferably made of the same material. Alternatively, they are made of different materials.

The first link arm, the second link arm and the third link arm may have different lengths. Alternatively, the first link arm, the second link arm and the third link arm may have substantially the same length. The first link arm, the second link arm and the third link arm are preferably made of the same material. Alternatively, they are made of different materials.

The rotation pin may be entirely arranged within the profile element housing. The link arm system may be entirely arranged within the profile element housing.

The profile element housing may be made of metal. The profile element housing may be formed by an extrusion process. As such, the profile element housing may be made in one piece, and is thus easy to produce. Furthermore, such a module is generally easier to assemble.

The first link arm and the rotation pin may be integrally formed.

Hereby, the risk of the mechanical connection between the rotation pin and the firs link arm faulting is minimized. Furthermore, the link arm system is generally easier to produce.

The link arm system may be configured such that an instantaneous ratio of the motion of the second end portion of the second link arm and the rotational motion of the rotation pin varies depending on a rotation angle of the rotation pin about the axis of rotation.

Hereby, a non-linear relationship between motion of the second link arm and the rotation of the rotation pin may be provided. As such, a nonlinear relationship between the input force from an actuator, to which the second link arm is mechanically connected when in use, to the second link arm and the rotation of the rotation pin is provided. Thus, the module may e.g. be configured to apply a large torque to the openable and closable element at small rotation angles of the rotation pin and a smaller torque to the openable and closable element at large rotation angles of the rotation pin. For example, when the module is mechanically connected to a door leaf arranged in a door frame, the module may be configured to apply a large torque at small opening angles, i.e. when the door leaf makes a small angle in relation to the door frame, and a decreasing torque with larger opening angles.

The module may further comprise a bracket assembly attached to the end portion of the rotation pin in a torsionally fixed manner and configured to be fastened to the openable and closable element.

By mechanically connecting the module to an openable and closable element via a bracket assembly, a larger area of contact between the module and the openable and closable element may be achieved. As such, the force applied to the openable and closable element may be spread out over the element, and thus not damage it. Furthermore, the bracket assembly may increase the lever arm by which the module acts on the openable and closable element.

Furthermore, the bracket assembly may provide a mechanically strong link between the module and the openable and closable element.

The bracket assembly may preferably be made out of a strong and durable material, such as metal.

The bracket assembly may comprise a rotation arm and a fastening element; wherein the rotation arm being attached, at a first end portion thereof, to the end portion of the rotation pin in a torsionally fixed manner, wherein the fastening element being rotatable about the axis of rotation and configured to be fastened to the openable and closable element, and wherein a second end portion of the rotation arm may be connected to the fastening element.

Thus, the rotation arm of the bracket assembly may be configured to act on the openable and closable element via the fastening element of the bracket assembly. Hereby, a larger lever arm acting on the openable and closable element may be provided. Furthermore, a larger area of contact between the module and the openable and closable element may be achieved. As such, the force applied to the openable and closable element may be spread out over the element, and thus not damage it.

The second end portion of the rotation arm may be displaceably connected to the fastening element, such that an angle of a longitudinal extension of the rotation arm in relation to a longitudinal extension of the fastening element may be alterable.

Since the fastening element typically is, when in use, fastened to the openable and closable element, and the rotation arm is acting on the fastening element. The effective lever arm acting on the openable and closable element may be altered by altering the angle between the rotation arm and the fastening element. Thereby, the torque and thus the characteristic of the rotational motion transferred from the module to the openable and closable element may be altered. The bracket assembly may further comprise an eccentric element and wherein the second end portion of the rotation arm is attached to the fastening element via the eccentric element such that the angle of the longitudinal extension of the rotation arm in relation to the longitudinal extension of the fastening element may be alterable by rotation of the eccentric element.

By providing an eccentric element which in practice connects the rotation arm to the fastening element, the angle between the rotation arm and the fastening element may be altered to some extent by rotating the eccentric element. Hence, the torque and thus the characteristic of the rotational motion transferred from the module to the openable and closable element may be altered in a simple but yet reliable manner. In this way the module may be adapted to a certain door having a certain characteristic.

The rotation of the eccentric element may be lockable by means of a locking member arranged in the eccentric element.

Hereby, the effective lever arm of the rotation arm acting on the fastening element may be locked or fixated.

The at least one inner surface of the profile element housing defining the track may be provided with a material having an increased wear resistance as compared to a wear resistance of the profile element housing.

Hereby, the longevity of the module may be increased.

According to a second aspect of the present invention, a system comprising a module according to the first aspect of the present invention is provided, the system comprising a frame and an openable and closable element, such as a door leaf, pivotably hinged in the frame about an element axis of rotation, the system further comprising at least one bracket assembly fixedly arranged on the openable and closable element so as to co-rotate with the openable and closable element about the element axis of rotation, wherein the module is mechanically connected to the openable and closable element via the bracket assembly. The technical effects and benefits discussed in relation to the first aspect applies mutatis mutandis to the third aspect and will consequently not be repeated to avoid undue repetition.

The module may be arranged in the frame, such that it is substantially flush with at least one outer surface of the frame.

Detailed description

In the following detailed description, some variants of the present inventive concept will be described. However, it is to be understood that features of the different variants are exchangeable between the variants and may be combined in different ways, unless anything is specifically indicated. Even though in the following description, numerous details are set forth to provide a more thorough understanding of the present invention, it will be apparent to one skilled in the art that the present invention may be practiced without these details. In other instances, well known constructions or functions are not described in detail, so as not to obscure the present invention.

Fig. 1 shows a module 1 according to the first aspect. The module 1 is configured for transferring rotational motion to an openable and closable element 10 (shown in Fig. 5). An openable and closable element may for example be a door leaf, a window, a gate or a bar. The module 1 is further configured to be mechanically connected to an actuator 4 (shown in Fig. 3). The actuator 4 is adapted to act on and transfer power to the module 1 . The actuator may be an opener or a closer common in the art. For example, the actuator device may be a closer comprising a spring assembly configured to be compressed from a first state to a second state during opening of an associated openable and closable element, and further configured to be decompressed from the second state to the first state, whereby an associated openable and closable element is closed. Alternatively, the actuator is an opener. An opener is described in detail in relation to Fig. 3.

The module 1 comprises a profile element housing 2 and a link arm system 3 adapted to be at least partially arranged in the profile element housing 2. The link arm system 3 comprises a first link arm 5 and a second link arm 7. The second link arm 7, at a first end portion 7A thereof, is rotatably connected to a first end portion 5A of the first link arm 5. The first link arm 5 and the second link arm 7 are rotatably connected with a first link arm pin 9. As such, the second link arm 7 may be rotated with regards to the first link arm 5 such that a relative angle a between the link arms 5, 7 may be varied. The link arm system further comprises a third link arm 11 configured to be mechanically connected to the actuator. The third link arm 11 is rotatably connected to the second end portion 7B of the second link arm 7 by means of a second link arm pin 13 around which the second link arm 7 is configured to rotate. As such, motion of the third link arm 11 is translated to a composite rotational and linear motion of the second link arm 7. Hereby, motion of the third link arm 11 along the profile element housing 2 is translated into a composite rotational and linear motion of the second link arm 7. The module 1 further comprises a rotation pin 15 having an axis of rotation RA. The rotation pin 15 is extended along the axis of rotation RA. The rotation pin 15 is configured to be mechanically connected to the openable and closable element 10. The rotation pin 15 is attached to a second end portion 5B of the first link arm 5 in a torsionally fixed manner. This means that any rotation of the second end portion 5B of the first link arm 5 will be directly transferred to the rotation pin 15, which in turn may transfer the rotation to an openable and closable element 10. The first link arm 5 and the rotation pin 15 may be integrally formed. The direction of rotation of the rotation pin 15 around the axis of rotation RA may be altered. The direction of rotation may e.g. be altered by arranging the third link arm 11 in the opposite direction than the direction depicted in Fig. 1. Furthermore, the through-hole 29 may be arranged on the opposite side of the profile element housing 2.

The link arm system 3 is thus configured such that motion of the second end portion 7B of the second link arm 7, via the first link arm 5, is translated to rotational motion of the rotation pin 15, thereby enabling a rotation of an associated openable and closable element 10. Hereby, the depicted link arm system 3 is configured such that an instantaneous ratio of the motion of the second end portion 7B of the second link arm 7 and the rotational motion of the rotation pin 15 varies depending on a rotation angle of the rotation pin 15 about the axis of rotation RA. Thus, a non-linear relationship between motion of the second link arm 7 and the rotation of the rotation pin 15 is provided. As such, a non-linear relationship between the input force from an actuator 4 (Fig. 3), to which the second link arm 7 is mechanically connected when in use, to the second link arm 7 and the rotation of the rotation pin 15 is provided. Thus, the module 1 may e.g. be configured to apply a large torque to the openable and closable element 10 at small rotation angles of the rotation pin 15 and a smaller torque to the openable and closable element 10 at large rotation angles of the rotation pin 15. For example, when the module is mechanically connected to a door leaf 10 arranged in a door frame 12 (see the system 8 in Fig. 5), the module 1 may be configured to apply a large torque at small opening angles, i.e. when the door leaf 10 makes a small angle in relation to the door frame 12, and a decreasing torque with larger opening angles.

The depicted link arm system 3 is in practice configured such that motion of the third link arm 11 , via the first link arm 5 and the second link arm 7, is translated to rotational motion of the rotation pin 15, thereby enabling a rotation of an associated openable and closable element 10.

A graph displaying the non-linear relationship of the module of Fig. 1 is shown in Fig. 2. The dotted line represents torque arm in a relative scale as a function of opening angle in degrees of the openable and closable element in relation to a default position. As such, 0 degree opening angle may entail a door leaf that is arranged in a door frame being in a closed position. As is visible, the torque arm is higher for small opening angles. A module according to the present inventive concept may thus provide a higher torque at small opening angles.

Returning to Fig. 1 , the profile element housing 2 is adapted to receive and support the link arm system 3 and the rotation pin 15. Hereby, second link arm pin 13 is provided with at least one sliding element 17. Here, the second link arm pin 13 is provided with a first and a second sliding element 17 in form of a wheels. The sliding element 17 is configured to slide along an interior track 19 of the profile element housing 2. The interior track 19 is defined by at least one inner surface 21 of the profile element housing 2. The at least one inner surface 21 further at least partially defines a first chamber 25 adapted to receive and support the third link arm 11 via the sliding elements 17 in form of wheels. Alternatively, a sliding element may be a sliding block. A sliding block may e.g. have a shape complementary to the interior track 19. A sliding block may further be made of a low friction material, or may comprise a layer of low friction material such that the layer of low friction material is arranged against the interior track 19. Here, the interior track 19 is a straight track arranged along a longitudinal extension of the profile element housing 2. The first and second sliding element 17 are thus configured to guide the linear motion of the third link arm 11 along the interior track 19, wherein the linear motion of the third link arm 11 is translated to a composite rotational and linear motion of the second link arm 7, which in turn is translated, via the first link arm 5, to rotational motion of the rotation pin 15. The at least one inner surface 21 of the profile element housing 2 defining the track 19 may be provided with a material having an increased wear resistance as compared to a wear resistance of the profile element housing 2.

The profile element housing further comprises a slit 23 connecting the first chamber 25 to a second chamber 27 of the profile element housing 2. The slit 23 allows for movement of the link arm system 3 when the link arm system 3 and the rotation pin 15 are arranged in the profile element housing 2.

The profile element housing 2 further comprises a through-hole 29 for receiving and supporting the rotation pin 15 such that the rotation pin 15 is pivotably hinged to the profile element housing 2 about the axis of rotation RA when the rotation pin 15 is arranged within the through-hole 29. An end portion 15A of the rotation pin is accessible from an outside of the profile element housing 2. The rotation pin 15 may have varied length. As such, the end portion 15A may be arranged below an outer surface 2A of the profile element housing 2 as seen in Fig. 1. Alternatively, the end portion 15A may be substantially flush with the outer surface 2A of the profile element housing 2. Alternatively, the end portion 15A may be arranged above the outer surface 2A of the profile element housing 2 as seen in Fig. 1 .

The end portion 15A of the rotation pin 15 further comprises a serrated surface 31 . The serrated surface 31 is e.g. configured to engage with a complementary serrated surface 33 of a bracket assembly 35 (shown in Fig. 4A and 4B).

Fig. 3 shows an exemplary module 1 when assembled and mechanically connected to an actuator 4. The actuator 4 is arranged within a longitudinal profile element 6. Here, the depicted actuator 4 is an opener. The opener may be configured to both open and close and openable and closable element. The opener 4 comprises an electric motor 14, a connection housing 16, an actuation screw and a spring assembly 18. The electrical motor 14 is configured to provide power to the connection housings 16, which in turn is configured to drive the actuation screw which provides linear motion to the spring assembly 18. The linear motion of the spring assembly 18 is in turn translated to the associated openable and closable element 10. As such, the electrical motor 14 is configured to transfer power to an associated openable and closable element 10 via the module 1.

Fig. 4A shows a bracket assembly 35 according to the present invention from a top view, whereas Fig. 4B shows the same bracket assembly 35 from a bottom view. The bracket assembly 35 is preferably made out of a strong material, such as metal. The bracket assembly further comprises a rotation arm 37 and a fastening element 39. The fastening element 39 is configured to be fastened to an openable and closable element.

The rotation arm 37 is configured to be attached, at a first end portion 37A thereof, to the end portion 15A of the rotation pin 15 in a torsionally fixed manner. To this end, the serrated surface 33 of a bracket assembly 35 is configured to engage with the serrated surface 31 of the rotation pin 15. Furthermore, a second end portion 37B of the rotation arm 37 is connected to the fastening element 39.

Here, the second end portion 37B of the rotation arm 37 is displaceably connected to the fastening element 39. As such, an angle [3 of a longitudinal extension LA1 of the rotation arm 37 in relation to a longitudinal extension LA2 of the fastening element 39 is alterable.

In Fig. 4A and 4B, the rotation arm 37 is displaceably connected to the fastening element 39 via an eccentric element 41 . The eccentric element 41 is arranged in a generally elliptical through-hole 43 such that movement of the eccentric element 41 is restricted by the elliptical through-hole 43. The elliptical through-hole 43 may have any other oblong shape. A position of the eccentric element 41 may as such be changed within the elliptical through- hole 43. The eccentric element 41 comprises a means for receiving a tool 45 adapted to receive a tool for changing the position of the eccentric element 41 . Here, the means 41 has a hexagonal shape, and is thus configured for receiving e.g. a hex key. By changing the position of the eccentric element 41 , the angle [3 of a longitudinal extension LA1 of the rotation arm 37 in relation to a longitudinal extension LA2 of the fastening element 39 is altered. The eccentric element 41 may further be lockable by means of a locking member 47 arranged in the eccentric element 41. As such, the position of the eccentric element 41 in the elliptical through-hole 43 may be fixed.

Returning to Fig. 2. The eccentric element 41 may further alter the effective opening angle of the openable and closable element, when it is in a closed position. The eccentric element 41 is e.g. configured to set the opening angle within an interval of 10 degrees. For example, arrangement of the eccentric element 41 may be set such that the resulting opening angle is -5 degrees, which results in an even larger torque arm, and thus resulting torque.

Fig. 5 shows a system 8 according to the second aspect of the present invention, comprising a module 1 attached to a longitudinal profile element 6. The longitudinal profile element houses an actuator 4 mechanically connected to the module 1 . The module 1 and the longitudinal profile element 6 are arranged in a door frame 12. The system 8 further comprising a bracket assembly 35 fixedly arranged on the openable and closable element 10 so as to co-rotate with the openable and closable element 10 about the element axis of rotation

In the claims, any reference signs placed between parentheses shall not be construed as limiting the claim.
