Technical Field

The present disclosure relates to a wall panel connection device, and especially to wall panel connection device for mounting a wall accessory to a wall panel system, and method of mounting a wall accessory to a wall panel system.

Background

The exterior of buildings may be provided with arrangements of wall panels. The flat surface of the building is thereby provided with arrangements and solutions for mounting wall panels. The mounted wall panels may be designed to provide important facade functions such as thermal insulation, acoustic insulation, or improved weather resistance. Additionally, the wall panels may be designed to provide an aesthetic impression.

In many solutions, the wall panel system comprises structural rails fastened to the surface of the building, and wherein the wall panels are fastened to the rails by for example screws, nails or bolts. The structural rails may be prefabricated with threads so as to engage the screws or bolts used to fasten the wall panel to the structural rails. The structural rails may be specifically configured to engage a certain type of wall panel with a certain type of bolt or screw which facilitates installation of the wall panel against the structural rail.

A problem with a building exterior covered with such wall panel system arises when an accessory is needed to be arranged to the building, since the accessory typically needs to be anchored in the building. It may be difficult to reach the building surface behind the wall panel system, and the wall panels may not be of a material or having a surface that is suitable for anchoring accessories.

Consequently, there is a need for a solution to the above identified problem when there is a need to anchor an accessory to a building having a wall panel system. Summary

It is an object of the present invention to provide an improved solution that alleviates the mentioned drawbacks with present devices. Furthermore, it is an object to provide a device and method for anchoring an accessory to a wall panel system.

The invention is defined by the appended independent claims, with embodiments being set forth in the appended dependent claims, in the following description and in the drawings.

According to a first aspect of the invention, a wall panel connection device is provided, the wall panel connection device comprising at least one insertion member configured to be inserted into at least one opening in a wall panel mounting rail; and a protruding portion comprising at least one protruding member connected to the at least one insertion member, the protruding portion configured to, when in use, extend away from said wall panel mounting rail. The protruding portion comprises an accessory anchor receiving opening, and the at least one insertion member and/or the at least one protruding member is moveable between an insertion position in which the wall panel connection device is insertable into the at least one opening in the wall panel mounting rail, and a fixed position in which the wall panel connection device is fixed to the wall panel mounting rail.

The wall panel mounting rail may be part of a wall panel system, in which wall panel mounting rails are arranged to a surface of a building, and wall panels are arranged to the wall panel mounting rails. Besides the wall panels arranged to the wall panel mounting rails, there may be a need to attached other accessories to the building via the wall panel system, temporarily or long-term. Such accessory may be a scaffold, a sign or additional wall panels of some kind. The present invention provides a device for receiving such accessory anchor for arranging the accessory to the wall panel mounting rail. The wall panel mounting rail may be arranged in a horizontal manner. Alternatively, the wall panel mounting rail may be arranged in a vertical manner.

The wall panel mounting rail may comprise at least one opening for receiving the wall panel connection device. The at least one insertion member may be inserted into the opening of the wall panel mounting rail. The at least one insertion member and/or the at least one protruding member may be moveable between the insertion position and the fixed position. The insertion position may be a position wherein the components of the wall panel connection device is arranged to enable or facilitate insertion of the wall panel connection device into the opening of the wall panel mounting rail. The fixed position may be a position wherein the components of the wall panel connection device is arranged to enable fixation of the wall panel connection device to the wall panel mounting rail.

By providing a wall panel connection device that may be easily arranged to a wall panel mounting rail for receiving an accessory anchor, a reliable and secure connection between the accessory and the wall panel system may be provided. The connection between the accessory and the wall panel system may further not be dependent on being arranged before any wall panels are arranged to the wall panel mounting rails, or be dependent on an attachment to the wall panels itself. Instead, a high degree of freedom in connecting the accessory to the building via the wall panel system at any time, when the need occurs, may be provided.

When in use in the fixed position, the wall panel connecting device may be locked to the wall panel mounting rail at least in a direction perpendicular to a front surface of the wall panel mounting rail. Further when in use in the fixed position, the wall panel mounting device may be lock to the wall panel mounting rail in a direction in parallel to the plane of the front surface of the wall panel mounting rail, which direction may be the direction in which gravity acts. Hence, the wall panel connection device may in the fixed position to a wall panel mounting rail be secured from being removed in said directions.

The accessory anchor to be received in the accessory anchor receiving opening may be a hook, a catch, a snaplink, a screw, a bolt, a sprint or the like, configured to connect the accessory to the wall panel connection device. In some embodiments, the wall panel connection device may be locked in the fixed position by arrangement of an accessory anchor and/or an accessory to the wall panel connection device. The wall panel connection device may be locked in the fixed position when the accessory anchor is arranged in the at least one accessory anchor receiving opening.

In some embodiments, the at least one insertion member may comprise a groove configured to engage with the wall panel mounting rail when moved from the insertion position towards the fixed position. The groove may engage with an edge of the at least one opening of the wall panel mounting rail. When the groove engages with the wall panel mounting rail, the wall panel connection device may be fixed to the wall panel mounting rail in at least one, two, three or four directions.

In some embodiments, the at least one insertion member may comprise a first insertion member and a second insertion member, and the first and second insertion members may be moveable relative to each other. Each of the first and second insertion member may be configured to, when in use in the fixed position, engage with the wall panel mounting rail to fix the wall panel connection device to the wall panel mounting rail. Both the first and the second insertion member may comprise a groove, each configured to engage with the wall panel mounting rail. Each groove may engage with an edge of an opening of the wall panel mounting rail. The groove of the first insertion member may engage with an edge of one opening of the wall panel mounting rail, and the groove of the second insertion member may engage with a different edge of the same opening, or an edge of a different opening of the wall panel mounting rail.

In some embodiments, the first and second insertion members may be moveable relative to each other between the insertion position and the fixed position. By being moveable relative to each other it may be meant that when being moved from the insertion position to the fixed position, at least one of the first and second insertion member is being moved relative to the other insertion member. One of the insertion members, e.g. the second insertion member, may, when the wall panel connection device is moved from the insertion position towards the fixed position, be static relative to the wall panel mounting rail, and the other (first) insertion member may be moved relative to the second insertion member, and relative to the wall panel mounting rail. In one embodiment, both insertion members move relative to the wall panel mounting rail when being moved towards the fixed position. The relative movement between the two insertion members may be a linear movement or a rotational movement. When moving relative to each other towards the fixed position, at least one of the insertion members may be moved into engagement with the wall panel mounting rail, which engagement may provide that the wall panel connection device may be prevented from being moved relative to the wall panel mounting rail in at least one, two, three or four directions. In some embodiments, the protruding portion may comprise a first protruding member and a second protruding member, and wherein the first protruding member is moveable relative to the second protruding member when moving the wall panel connection device between the insertion position and the fixed position. The first and second protruding members may be configured such that the relative movement between the two protruding members may cause the relative movement between the two insertion members. This may further cause the wall panel connection device to move between the insertion position and the fixed position. The wall panel connection device may comprise a first part and a second part, wherein the first part may comprise the first insertion member and the first protruding member, and the second part may comprise the second insertion member and the second protruding member. The two parts may be moveable relative to each other. The movement of the two parts relative each other may provide the movement of the wall panel connection device between the insertion position and the fixed position.

In some embodiments, the at least one protruding member may be integrally formed with at least one of said at least one insertion member. When the wall panel connection device comprises a first and second insertion member and a first and second protruding member, the first protruding member may be integrally formed with the first insertion member and/or the second protruding member may be integrally formed with the second insertion member. A solid connection between the respective protruding and insertion members may thereby be provided. Further, any movement between respective protruding members may be directly transferred to the respective insertion members.

In some embodiments, the first and second insertion members may be moveable relative to each other by means of operation of the at least one protruding member. The at least one protruding member may be operable to move at least one insertion member such that the moved insertion member moves relative to the other insertion member. In an embodiment wherein the wall panel connection device comprises a first and second insertion member and a first and second protruding member, either one or both of the protruding members may be operated to cause movement of either one or both of the insertion members. In one embodiment, the first protruding member is operated to move the first insertion member. In one embodiment, the first and the second protruding members are operated to move the first and second insertion members. The first protruding member may be operated to move the first insertion member, and the second protruding member may be operated to move the second insertion member.

In some embodiments, the at least one insertion portion may comprise a first insertion member and a second insertion member, and the protruding portion may comprise a first protruding member and a second protruding member, and the first insertion member may be integrally formed with the first protruding member and the second insertion member may be integrally formed with the second protruding member. The wall panel connection device may comprise a first part and a second part, wherein the first part may comprise the first insertion member and the first protruding member, and the second part may comprise the second insertion member and the second protruding member. Further, the two members in the respective parts may be integrally formed, or at least in direct connection and fixed to each other. The two parts may be moveable relative to each other. The movement of the two parts relative each other may provide the movement of the wall panel connection device between the insertion position and the fixed position. The two parts may in some embodiments be identically shaped, or mirror copies of each other. When in the fixed position, the two parts may be in contact with each other. Alternatively, when being moved towards the fixed position, the two parts may move towards each other, but when in the fixed position, the two parts may be distanced from each other.

In some embodiments, each of the first and second protruding members may comprise an accessory anchor receiving opening, wherein the respective openings are configured to, when in the fixed position, be aligned. The two protruding members may be moveable relative each other when moving between the insertion position and the fixed position. The two protruding members may in the fixed position at least partly abut each other, for instance by laying as two layers against each other. Each protruding member may comprise an accessory anchor receiving opening. When in the fixed position, the two protruding members may have moved into a position wherein the two accessory anchor receiving openings are aligned. An accessory anchor may thereby be inserted into the accessory anchor receiving opening such that it extends through both protruding members. The two protruding members, and thereby the entire wall panel connection device, may thereby be locked in the fixed position.

In some embodiments, the first and second insertion members may be configured to be inserted into different respective openings in the wall mounting rail and moved towards each other into respective engagement with the wall panel mounting rail when moved towards the fixed position. Each insertion member may be provided with a hook shape or a groove, or the like, in order to engage with the wall panel mounting rail. When in the insertion position, each insertion member may extend into the respective opening without engagement with the wall panel mounting rail. When moving towards the fixed position, the shape of the insertion members provide respective engagement with the wall panel mounting rail. The engagement between the insertion members and the wall panel mounting rail may locks the wall panel connecting device to the wall panel mounting rail at least in a direction perpendicular to a front surface of the wall panel mounting rail. The engagement between the insertion members and the wall panel mounting rail may further lock the wall panel connecting device to the wall panel mounting rail in a direction in parallel to the plane of the front surface of the wall panel mounting rail, which direction may be the direction in which gravity acts.

In some embodiments, the first and second protruding members may each comprise at least one sprint receiving opening configured to, in the fixed position, be aligned such that a sprint received through both sprint receiving openings fixes the wall panel connection device in the fixed position. The two protruding members may be moveable relative each other when moving between the insertion position and the fixed position. The two protruding members may in the fixed position at least partly abut each other, for instance by laying as two layers against each other. Each protruding member may comprise a sprint receiving opening. When in the fixed position, the two protruding members may have moved into a position wherein the two sprint receiving openings are aligned. A sprint may thereby be inserted into the sprint receiving opening such that it extends through both protruding members. The two protruding members, and thereby the entire wall panel connection device, may thereby be locked in the fixed position. The sprint receiving openings may be provided in addition to the accessory anchor receiving opening. The sprint receiving openings may provide a function for locking the wall panel connecting device in the fixed position by arranging a sprint therein. The spring may be formed as a spring cotter pin.

In some embodiments, the wall panel connecting element may further comprise a spring configured to spring bias the at least one insertion member and/or the at least one protruding member towards the fixed position. When spring biased towards the fixed position, the spring may provide a function of locking the wall panel connecting device in the fixed position. In order to remove the wall panel connecting device from an engagement with the wall panel mounting rail, or to introduce the wall panel connecting device into the opening of the wall panel mounting rail, the spring force needs to be overcome. When in the insertion position, the spring may be compressed. When the force counteracting the spring force is released, the spring acts on the insertion member and/or the protruding member to move towards the fixed position.

In some embodiments, the at least one insertion member may comprise a first insertion member and a second insertion member moveable relative to each other between the insertion position and the fixed position, the protruding portion may comprise a first protruding member and a second protruding member, wherein the first insertion member may be connected to the first protruding member and the second insertion member may be connected to the second protruding member, and wherein the spring is configured to act on the first and second protruding members. By being connected it may be meant that the respective insertion and protruding members are integrally formed, directly connected to be moveably fixed relative each other, or connected such that movement of one of the members is directly transferred to the other of the members. The wall panel connecting device may be described as comprising two parts, wherein a first part comprises the first insertion member and the first protruding member, and a second part comprises the second insertion member and the second protruding member, the two parts being moveable relative to each other. In one embodiment, the two parts may be arranged in a scissor arrangement relative to each other. The two parts may rotate relative each other in the scissor arrangement around a rotation point provided by a rotation axis. The spring may act on the respective protruding members. The spring may be arranged between the two protruding members, biasing the protruding members to move away from each other. The scissor arrangement thereby provides that the two protruding members biased to move away from each other also biases the insertion members to move away from each other. When in use on a wall panel mounting rail, the insertion members being biased to move away from each other may provide that each insertion member, in the fixed position, may engage with a side edge of the opening in the wall panel mounting rail. Each insertion member may have an end portion for instance formed as a shoulder, hook or similar that may be configured to abut a back surface of the wall panel mounting rail. When removing the wall panel connection device from the wall panel mounting rail, the spring may be compressed such that the insertion members move towards each other, and releases their engagement with the wall panel mounting rail.

With the first and second parts of the wall panel connecting device in a scissor arrangement, the accessory anchor receiving opening may be in the protruding portion between the rotation point and the insertion members. The insertion of an accessory anchor may thereby prevent the wall panel connection device from moving to the insertion position, preventing the wall panel connection device from being removed from engagement with a wall panel mounting rail.

In some embodiments, the protruding portion may further comprise a connection member comprising the accessory anchor receiving opening, the first and second protruding members being moveable relative to the connection member. The connection element may be formed as a housing at least partly enclosing the protruding members. The accessory anchor receiving opening may be provided in said connection element. End portions of the two protruding members may extend out through a first end side of the connection member. End portions of the two insertion members may extend out through a second end side of the connection member. The first and second end sides may be opposite of each other, and may be open. The connection member may be formed of a top side, a bottom side and two longitudinal side portions. The top side and the bottom side may be connected to each other by said two longitudinal side portions. Each longitudinal side portion may extend between the first and second end sides. The two longitudinal side portions may each have a bent shape following the scissor arrangement of the two parts of the wall panel connection device. In some embodiments, the second insertion member may be a fixed insertion member configured to, when in use, be inserted into the opening of the wall panel mounting rail and to abut a back surface of the wall panel mounting rail, and the first insertion member may be a moveable insertion member configured to, when in use, be inserted into the opening of the wall panel mounting rail and moveable to the fixed position to abut said back surface of the wall panel mounting rail. In the insertion position, the first insertion member may not be in contact with the back surface of the wall panel mounting rail. The first insertion member may be moveable relative to the second insertion member. The first insertion member may further be moveable relative to at least one of the first and second protruding members, and/or relative to the wall panel mounting rail when inserted into the opening. The second insertion member may be fixed relative to at least one of the first and second protruding members, and/or relative to the wall panel mounting rail when inserted into the opening.

In some embodiments, the second protruding member is a fixed protruding member configured to, when the wall panel connection device is arranged to the wall panel mounting rail, abut a front surface, opposite said back surface, of the wall panel mounting rail. The second protruding member may further be fixed relative to the second insertion member. The second insertion member and the second protruding member may, when arranged to the wall panel mounting rail, either in the insertion position or in the fixed position, abut respective opposite sides of the wall panel mounting rail.

In some embodiments, the first protruding member may be moveable to move the first insertion member between the insertion position and the fixed position. The first protruding member may be operable, rotatably and/or axially, to move the first insertion member. After insertion into the opening of the wall panel mounting rail, the first insertion member, being moveable relative to at least the second insertion member, may be operated by moving the first protruding member.

In some embodiments, the first protruding member may be connected to the first insertion member via a shaft, and the first insertion member, when being moved towards the fixed position, may rotate around said shaft and move axially along said shaft. The first protruding member may be operated to move the first insertion member both rotatably and axially into the fixed position. When in the fixed position, an end portion of the first insertion member may abut the back surface of the wall panel mounting rail, thereby locking the wall panel connection device to the wall panel mounting rail. The shaft may be a threaded shaft, and the first insertion member may receive the shaft in a threaded opening, providing a threaded engagement between the first insertion member and the shaft. The first protruding member may be rotationally and axially fixed relative to the shaft. Rotation of the first protruding member may cause both rotational and axial movement of the first insertion member, depending on the orientation of the first insertion member. Without any further influence from other components, a rotation of the first protruding member may cause a rotation of the first insertion member. If the first insertion member is in contact with the back side of the wall panel mounting rail, a rotation of the first protruding member may cause an axial movement of the first insertion member towards the back side of the wall panel mounting rail, by means of the threaded shaft. In an alternative embodiment, the axial movement of the first insertion member may be provided by a spring biasing the first insertion member towards the back surface of the wall panel mounting rail, and the rotational movement of the first insertion member may be provided by rotation of the first protruding member.

In some embodiments, the at least one protruding member extends in a plane perpendicular to a plane in which the at least one insertion member extends. The plane in which the at least one protruding member extends may, when in use, be substantially in parallel to a front surface of the wall panel mounting rail.
