BATTEN FIXING SYSTEM
In accordance with an aspect of the present invention, a batten fixing system includes a clip having an attachment to attach the clip to a surface so that a first side of the clip faces the surface, and having parallel spaced rails on a second, opposite side of the clip to the first side. The batten fixing system further includes an engagement profile provided on a batten, the engagement profile having spaced apart feet that are held in engagement under force by the parallel rails of the clip.
The invention relates to batten fixing systems.
BACKGROUND OF THE INVENTIONArchitectural decorative linings are becoming more widely used for external claddings and facades, as well as internal ceilings and feature walls. These linings can be in the form of linear timber or aluminium battens that are secured to the structure for aesthetic appeal. For example, spaced apart battens may be applied to a wall for purely aesthetic appeal, or they may form the structure of an external wall/divider to provide both an aesthetically appealing and functional structure. The fabrication and installation of these products can be difficult, which can impact the commerciality of the products and timeframes to get the product installed on the work site. For example, there is a higher demand in meeting architect specifications, such as concealment of the fixings and an aesthetic look, while providing a product that is relatively simple to install. Most commercial facades are designed and engineered on a project specific basis rather than being based on an efficient, pre-engineered, modular system.
It is in light of the complexity of the design, engineering, fabrication and installation of architectural decorative linings that the invention was conceived.
SUMMARY OF THE INVENTIONThe invention provides a batten fixing system comprising:
a clip having an attachment to attach the clip to a surface so that a first side of the clip faces the surface, and having parallel spaced rails on a second, opposite side of the clip to the first side; and
an engagement profile provided on a batten, the engagement profile having spaced apart feet that are held in engagement under force by the parallel rails of the clip.
It will be understood that the term batten includes items such as facade blades and fins.
The batten fixing system may also comprise a locking piece located on the clip to anchor one of the feet to the clip, preferably by setting the foot in compression. The locking piece may include a biasing member, such as an upstanding barb, that bears against one of the feet to force the foot into compressed engagement between one of the rails and the locking piece. The locking piece may be substantially rigid but may exhibit a small degree of resilience. The upstanding barb may cut into one of the feet to restrict relative movement between the clip and the engagement profile.
The clip may further have a protruding guide positioned near and biased towards one rail, the protruding guide defining a gap with the rail into which a foot can be guided and latched under bias from the guide. The protruding guide may include a curve that deflects to widen the gap and guide the foot into the gap.
The spacing between the feet, measured at a base of the feet, is defined by a section on the engagement profile that extends between the feet. The distance between outer extremities of the feet may be the same or larger than the distance between inner engagement surfaces on the rails. At least one of the feet or the rails may exhibit resilience. The feet may have underhooked ends that engage with overhooked ends on the rails.
By providing a resilient foot or rail the foot or rail can flex to allow assembly and to latch the underhooked/overhooked end of the corresponding foot/rail. If the feet are wider than the rails the feet may be held in place under compression between the rails.
The attachment on the clip may attach the clip to a track. The attachment may include the clip having flanges shaped to create a twist lock connection with the track.
The engagement profile may be formed with the batten frame. Alternatively, the engagement profile may be provided on an insert comprising a tenon extending from the engagement profile, where the tenon is adapted to be inserted and secured in a mortise of a batten.
The invention also provides a method of fixing a batten to a surface including: fixing a track to a surface; attaching a clip to the track; engaging a batten having an engagement profile on one side thereof to the clip by hooking a first foot of the engagement profile into engagement with a first rail of the clip, hinging the batten about the first foot and guiding a second foot of the engagement profile into engagement with a second rail of the clip so that the engagement profile is held in engagement under force by the clip.
The method may include fixing multiple tracks at spaced apart intervals, and fixing one or more clips to each track, wherein the clips are in line.
An embodiment, incorporating all aspects of the invention, will now be described by way of example only with reference to the accompanying drawings in which;
The engagement profile 40, which has a constant cross-sectional profile, can be integrally formed with the batten 50, as shown in
Alternatively, the engagement profile 40 may be a separate component that is connected or joined to the batten 50, as shown in

In order to connect the engagement profile 40 to the clip 20 one of the two feet 44, 45 is hooked into engagement with the hinging profile 24′ of the first rail 24. For example, the underhooked end 46 of the first foot 44 is positioned in the recess 27 (see
At this stage of connecting the engagement profile 40 to the clip 20 the batten 50 is at an angle to the clip 20 (as shown in
In other words, the first foot 44 is compressed between the locking piece 60 and the first rail 24 of the clip 20. At the same time, the upstanding barbs 64 cut into the ridge 49 of the first foot 44. The barbs 64 dig into the ridge 49 to anchor the foot resisting relative movement between the first foot 44 and the clip 20. At this stage of connecting the engagement profile 40 to the clip 20 the batten 50 is not yet perpendicular to the clip 20.
Still further rotation of the engagement profile 40 about the hinging profile 24′ guides the second foot 45 to latch into engagement with the second rail 25 of the clip 20 by flexing the second foot 45 so that the underhooked end 47 of the second foot 45 can pass the overhooked end 28 of the second rail 25. The second foot 45 is sufficiently resilient so that the underhooked end 47 of the second foot 45 is latched by the latch 29, thereby preventing the engagement profile 40 from rotating out of engagement with the clip 20 (i.e. through a latching force). In this position the underhooked ends 46, 47 of the feet 44, 45 engage with the overhooked ends 26, 27 of the rails 24, 25 and the batten 50 is perpendicular to the clip 20. The engagement profile 40 and the clip 20 are held in engagement by force (namely the compression force on the first foot 44 and the latching force on the second foot 45). The “rolling in” of the engagement profile 40 into the clip 20 allows for easy assembly of the batten fixing system 10.
The upstanding barbs 64 of the locking piece 60 resist relative sliding or slipping movement between the clip 20 and the engagement profile 40. For example, if the batten fixing system 10 is used for attaching a batten 50 vertically (see
The distance between the outer extremities of the feet 44, 45 may be larger than the distance between inner engagement surfaces on the rails 24, 25 (i.e. the hinging profile 24′ and the latching profile 25′). The feet 44, 45 of the engagement profile 40 may therefore be under compression when attached to the clip 20.
The clip 20 also has a protruding guide 70 positioned near and biased towards the second rail 25. The protruding guide 70 defines a gap between it and the second rail 25 into which the second foot 45 can be guided and latched under bias from the guide 70. The protruding guide 70 is curved and deflects to widen the gap and guide the second foot 45 into the gap as the engagement profile 40 is rotated into engagement.
The clip 20 is manufactured from a metal, such as aluminium. This allows the clip 20, which has a constant cross-sectional profile, to be extruded. A length of the clip extrusion can be formed and then cut to size to form several clips 20.
The clips also have a twist lock connection, such as bayonet type geometry, to assist in attaching clip to a surface, for example if the clip is to be attached to a track 80. The clip 20 is shaped to create the twist connection and has a first flange 74 and a second flange 76. The first flange 74 extends beyond the main body of the clip 20 in one direction and the second flange 76 extends beyond the main body of the clip 20 in an opposite direction. The first and second flanges 74, 76 have end surfaces 75, 77. The bayonet type geometry is formed by machining the extruded aluminium clips 20. The machining step may be carried out after the clips 20 have been cut to size. Alternatively, a single machining step can be used to cut the clips 20 to size and form the bayonet geometry. Standard machining, such as CNC milling, is used to form the bayonet type geometry.
Referring to
It will be understood that while the clip 20 has been described as being secured to the track 80 by rivets, it is possible to use any type of fastener or attachment means to secure the orientation of the clip 20. For example, screws, nuts and bolts or adhesives could be used to secure the orientation and position of the clip 20. For example, if the track is made from metal a tek screw could be used to secure the clip 20 to the track 80.
Once the clips 20 and tracks are installed the battens 50 can be easily attached to the clips via the engagement profile 40. If two or more tracks are used, the installation of the batten to the two in line clips 20 assists in keeping the clips in the correct orientation to engage the retaining arms 81, 82. The tracks may be attached to an existing wall. Alternatively the tracks 80 may be attached to a substructure that allows the attached battens to form a divider between two spaces. The tracks may be curved to fit curved walls or to create curved dividers. Due to the strength of the interaction between the bayonet type geometry of the clips 20 and the retaining arms 81, 82 of the track 80 it is possible to increase the spacing between the tracks 80. A strong connection is important in order to resist wind load and handle the weight of larger battens.
The clips 20 can be attached to the tracks 80 in a factory before they are transported to the final location for installation (i.e. for a pre-designed structure). This allows the quick and precise assembly of the battens 50 onto the clips 20 once the tracks 80 are installed. The modularity of the system allows workers at the factory to easily preassemble the clips 20 and tracks 80 to custom designs specified by the client (e.g. an architect).
For example, an architect can specify the size, shape and spacing of the battens to the designer. The designer then designs and manufactures the rails 80 and the battens 50, and attaches the clips 20 to the rails 80 before sending the rails 80 (with the mounted clips 20) and the battens 50 to the builder. The builder can then attach the rails 80 to an exterior or interior of the building (e.g., as shown in
Alternatively, the tracks 80, clips 20 and battens 50 can all be purchased separately and assembled on site to any desired set up.

The method of fixing a batten 50 to a surface includes: fixing a track 80 to a surface; attaching a clip 20 to the track 80; and engaging a batten 50 having an engagement profile 40 at an end thereof to the clip 20 by hooking a first foot 44 of the engagement profile 40 into engagement with a first rail 24 of the clip 20, hinging the batten 50 about the first foot 44 and guiding a second foot 45 of the engagement profile 40 into engagement with a second rail 25 of the clip 20 so that the engagement profile 40 is held in engagement under force by the clip 20.
The above steps do not need to proceed in the order identified above. For example, as described above, the clip 20 may be attached to the track 80 before the track is fixed to a surface.

The engagement profile 140 includes a section 148 extending between the feet 144, 145 to maintain the spacing between the feet 144, 145. Notably the spacing between the end of the feet 144, 145 and the root of the feet where they meet section 148 is greater than in the embodiment shown in
The batten fixing system 110 also has a locking piece 160 to set one of the feet 144, 145 in compression. The locking piece 160 is attached to the clip 120 as described above. The engagement profile 140 is attached to the clip 120 in the same manner as described above when referring to attaching engagement profile 40 to clip 20.
Each of the feet 144, 145 have underhooked ends 146, 147 and a ridge 149 at a lowermost part of each of the feet 144, 145. The engagement profile 140 is symmetrical, allowing it to be attached to the clip 20 in two orientations. In other words, the engagement profile 40 is reversible. The underhooked ends 146, 147 of the feet 144, 145 are wider than the space between the first and second rails 124, 125 so that the feet 144, 145 are held in place under compression between the rails 124, 125.
The first rail 124 and the second rail 125 of the clip 120 have different profiles. First rail 124 has a hinging profile formed by an overhooked end 126 that forms a recess 127. The second rail 125 has a latching profile formed by an overhooked end 128 that forms a latch 129. The latching area formed by the overhooked end 128 is greater than the latching area formed by the overhooked end 28 (shown in
Although engagement profile 140 is only shown connected to clip 120, the engagement profile 140 can also be used with clip 20. In addition, the engagement profile 40, whether integrated with the batten 50 (
Furthermore, the clips 20, 120 can be provided with variable spacings between the rails in order to accommodate batten engagement profiles of different widths. Referring specifically to

The batten 200 shown in
The attachment means is shown as a male and female connection, and more specifically as push-click system that allows a batten extension piece 210 or a nose piece 220 to be pushed directly into the batten 200. The batten has the female portion 202 of the push-click system. The extension pieces 210 have two attachment means, a male portion 212 at one end and a female portion 214 at the opposite end. This allows the extension pieces 210 to be stacked one on top of another to a desired depth. The extension pieces 210 can be supplied in different depths to suit the length and width of a base batten.
Referring to
The nose pieces 220 have a single attachment means, namely a male portion 221. A nose piece 220 may be attached to a base batten 200 or a batten extension piece 210 through the male portion 222. The nose piece can be formed as a flat end piece 228 or in various other shapes for aesthetic appeal as illustrated in
As shown in
The attachment means can also include an arm 204 that, once the male and female portions are connected, forms a hole for a screw. Referring to

It will be understood that multiple tracks 80 can be fixed at spaced apart intervals. A clip 20 can be fixed to each track with the two clips 20 being positioned in line with each other.
While the invention has been described as preferably having feet 44, 45 that locate between rails 24, 25, it is envisaged that the feet 44, 45 could be redesigned to locate on outer surfaces of the rails 24, 25 so that the feet 44, 45 are held in engagement under force by the first rail 24 and the second rail 25 of the clip 20. In other words, the rails 24, 25 of the clip can locate between the feet 44, 45 of the engagement profile.
Although the second foot 45 has been described herein as deforming to allow the underhooked end 47 of the second foot 45 to pass the overhooked end 28 of the second rail 25, the batten fixing system could still function if only at least one of the feet 44, 45 or the rails 24, 25 is flexible.
While the first foot 44 has been described as being compressed between the locking piece 60 and the first rail 24, the batten fixing system would function without the locking function. For example, the clip 20 or the foot 44 could be specifically shaped to allow the hinging action to function without the locking piece 60. Such a shape could, for example, include the foot ridge 49 being larger and shaped with an increasing radius to act as a cam against to allow the foot to hinge and then lock against overhooked end 26. In addition, for horizontally mounted ceiling battens the anti-slip functionality of the barbs 64 on the locking piece 60 provide a desired feature, rather than an essential feature.
It will be understood that while the upstanding elements on the locking piece have been described as barbs, the barbs could be any suitable structure, including tabs, that will assist in locking the engagement profile in position. For example, the locking piece may be made from a steel sheet that is pressed to form the barbs (protrusions) and the flanges 61, 62 (downwards extending elements).
The present batten fixing system provides a quick and simple to install pre-indexing system that can be formed according to architect design. The pre-engineered clips and interlocking engagement profile provide a system that unskilled persons can install with ease yet provide a professional, architectural appearance by way of the concealed fixings.
The battens, or blades, can also be made to an unlimited number of different designs, specifications and sequences that will in turn provide architects with an almost unlimited design palette.
While the batten fixing system has been described as being attached to an open building structure, such as a car park, it is envisaged that the batten fixing system can be used with any suitable building structure. For example, the batten fixing system can be used with an open or closed building structure. The batten fixing system can also be used with a multistory building.
