An example of a panel assembly will now be described in more detail with reference to Figures 1A through 1C.

In this example, panel assembly 100 includes a panel 110 that can be positioned within the opening. The opening can be in any suitable form depending on the application. In one example, the opening is defined by wall 102, such as forming part of a family home or other building, and thus may include a garage door opening, a window opening, or the like, with the panel acting as a door, window, or the like. Alternatively, however, the opening may be within the enclosure, with the panel as a wall panel, or the like.

The panel 110 includes a plurality of locking members 111, 112 that are spaced apart from each other along at least a portion of the length of the panel and adjacent the opposite longitudinal edges of the panel. In the present example, the locking members 111, 112 are disposed on the front face and the rear faces 110.1, 110.2 of the panel 110. However, while it is generally preferred to arrange, as described in more detail below, this is only the purpose of this example and is not required.

The panel assembly 100 also includes guides 130 extending along either side of the opening 101, each guide 130 including at least one locking flange 131, 132, two shown in this example. The locking flanges 131, 132 extend along at least a portion of the length of the guide 130, wherein the panel 110 is received in the guide 130 in use such that the locking members 111, 112 selectively engage the flanges 131, 132, thereby limiting the edge of the panel The lateral movement.

In particular, this arrangement prevents lateral movement of the panel relative to the guide 130 The movement, which in turn prevents the panel from being disengaged from the guide 130, such as under application of a load to the surface of the panel. Thereby, it can act as a wind lock operation, preventing the panel 110 from being unhooked by the guide 130 under wind load, while also providing a safety function to prevent the panel from being opened or removed due to pressure applied to the panel surface.

The locking members are generally spaced apart from one another along the length of the opposing longitudinal edges of the panel such that the panel is secured to the guide along at least a majority of its length, thereby providing maximum locking. In the case where the panel is a roller door, the maximum degree of locking is when the door is in its fully extended position, which in turn corresponds to the situation in which the load acting on the door is maximized due to the increased exposed area of the door.

In one example, panel 110 is a continuous panel of continuous sheet metal or other similar material having locking members created by dimples, grooves, push-outs, and slits in the panel material. This makes the locking mechanism easy to manufacture, for example during roll forming of the panel, making it possible to achieve a very inexpensive windlock arrangement. Furthermore, this can be done with lightweight materials. This makes the arrangement suitable for use in various situations and is particularly suitable for roller door assemblies that are used manually or with low power motors, so that the arrangement can be used in the home, but not before.

Several further features will now be described.

In the present example, the front and rear locking members 111, 112 extend outwardly from the front and rear faces 110.1, 110.2 of the panel, in which case the front and rear flanges 131, 132 are configured to guide. A portion of the piece to engage the front and rear locking members 111, 112, respectively. Although the use of the front and rear locking members 111, 112, and the respective front and rear flanges 131, 132 are not required, it should be understood that this can significantly enhance the strength of the locking effect. This in turn may allow for a sufficient degree of locking with a lightweight material such as aluminum, making the panel assembly particularly suitable for use in a home environment, although other materials such as steel or the like may be used. However, as mentioned above, this is not required and the lock The stationary member can optionally be provided by only one face, such as only the front or rear face, in which case only a single corresponding flange 131, 132 is provided on the guide 130.

In one example, each of the guide members 130 includes a channel 133 that includes front and rear faces 133.1, 133.2 having front and rear flanges 131, 132 extending inwardly from the front and rear faces. Although any suitable arrangement can be used.

Panel 110 generally includes a contoured profile that defines peaks and valleys, and the locking members extend outwardly from at least one of the peaks and valleys. For example, the front locking member 111 will extend outwardly from the peak of the front face while the rear locking member 112 will extend outwardly from the valley of the front face (corresponding to the peak of the back face), thereby making the front and back The distance between the tips of the locking members 111, 112 is maximized, which in turn maximizes the strength of the locking mechanism.

In one example, the peaks can have a different width than the valleys. But this is not required, and different sizes of peaks can be used, especially for larger peaks on the front side, which can have many benefits. For example, where it forms part of the roller door assembly, this allows the panel to roll more easily via having a narrower valley inside the roller. In addition, larger peaks on the front face are useful for accommodating locking mechanisms, or the like, as well as being more visually appealing.

As noted above, the locking member can be defined in any suitable manner, but is preferably defined by deformation of the panel, such as during a portion of the roll forming process. More preferably, the deformation does not create an opening or discontinuity in the panel material such that the deformation provides a continuous surface. This is done to avoid creating sharp edges that are detrimental to the installation of the panel and subsequent conditions, such as the locking member projecting outwardly from the guide. The rim may also be a locking member for grasping the edge of, for example, a guide or flange, or other locking member, when the panel is rolled up.

The panel may also include a reinforcing member positioned between at least some of the locking members and the edges of the panel. It can provide additional strength, and in particular it can prevent deformation of the panel along the edge of the panel under load, which in turn leads to failure of the locking member. Reinforced components can be any What is the appropriate form, but in one example, it includes a channel or ridge that extends generally parallel to the edge of the panel. This allows the reinforcing member to be deformed by the deformation of the panel, for example during roll forming or the like, so that this deformation can be achieved at the same time when the locking member is caused. The presence of the passage or ridge ensures that the force generated by the action of the locking member on the guide can be dissipated along the edge of the panel and not concentrated at individual locations on the edge of the panel, which in turn can result in deformation of the panel material, and thus Causes failure of the collapse and locking members.

In one example, panel 110 includes at least one sideband that extends along at least a portion of the opposite longitudinal edges of panel 110. More typically, the panel 110 includes a first and second strip mounted on the front face and the rear face. In general, the sidebands will typically be at least partially elastic and their action can be used to absorb impacts, thereby maintaining a quiet operation of the door under windy conditions.

The guide generally includes a passage for receiving the side strap and the locking member, and wherein the sideband gap between the side strap and the passage is smaller than a locking member gap between the locking member and the passage and a flange gap between the panel and the passage flange At least one of them. To achieve this, each of the guides can include a first channel portion of the locking member that receives the panel and a second channel portion that receives the sideband of the panel, wherein the second channel portion is narrower than the first channel portion. This ensures that when the panel is under lateral load, the sidebands can be brought into contact with the guide before contacting the panel or locking member, thereby minimizing noise.

In one example, the side straps may extend a greater distance outwardly from the door than the locking members 111, such that the side straps may protrude upwardly within the range of the locking members. This can be used to ensure that the locking members 111, 112 do not abut or impact the inner face of the guide, which in addition to the flanges 131, 132, etc., can in turn cause slamming and other undue noise. Therefore, the sidebands can minimize noise generated by wind or other loads applied to the panel 110. This also prevents the locking members from damaging each other when the panel is rolled up, such as in the case of a roller door.

Additionally, the side straps can provide a low friction surface against the inner surface of the guide to promote the rise and fall of the panel. Thus, the sidebands can be formed from any suitable material, and in one example, can be formed from polymeric materials, brush strips, or the like.

In one example, the panel is a continuous panel, although this is not necessary, and alternatively it may use a louver panel.

In one example, the panel assembly is part of a roller door assembly that can be a curtain that is moveable between a retracted position and an extended position, wherein the curtain can cover the opening when in the extended position.

In this case, the door assembly 100 can also include a drive assembly 120 that moves the panel 110 between a retracted position and an extended position. The drive assembly can be any form of drive assembly that can include, for example, a linear actuator, such as a garage door drive, or a roller assembly and associated drive, as will be described in more detail below. In one example, the drive assembly includes a roller assembly and a drive for rotating the roller assembly, although other arrangements can be used. However, this is not necessary, and alternatively, the door can typically be operated manually by raising or lowering through the panel.

An example of a door assembly will now be described with reference to Figures 2A and 2B.

In this example, it shows additional detail of an exemplary drive assembly 120. In the present example, the drive assembly 120 includes a roller assembly that includes a mounting barrel 221 coupled to a shaft 222 that is rotatably supported by a mounting bracket 223 that is coupled to the wall 102. One of the brackets 223 also supports a driver 224 that is coupled to the shaft 222 via a transmission member, such as a belt or chain 225 and a sprocket arrangement. In use, motor 224 rotates shaft 222 to cause corresponding rotation of mounting barrel 221 and to move curtain 110 between extended and retracted positions, as will be appreciated by those skilled in the art. It will also be understood by those skilled in the art that the motor can be omitted and the door curtain can be raised or lowered manually. In this case, a spring can be used to offset the shaft 222, Thereby the weight of the curtain 110 is counteracted, making it easier to raise or lower the curtain, as will be appreciated by those skilled in the art.

However, any suitable drive assembly can be used, while in another example, the motor can be integrated within the shaft, as will be appreciated by those skilled in the art.

A further exemplary panel assembly will now be described with reference to Figures 3A through 3F. In the present example, the reference number is increased by 200 to be used to indicate similar features as those shown in Figs. 1A to 1C.

In the present example, panel 310 includes front and rear locking members 311, 312 positioned on adjacent opposing edges of panel 310. Sidebands 315 are also mounted on each of the opposing edges as shown. In the present example, panel 310 includes peaks 313 and valleys 314 that extend laterally across panel 310, with front locking members 311 projecting outwardly from peaks 313 and rear locking members 312 projecting outwardly from valleys 314. As previously mentioned, this maximizes the lateral spacing between the tips of the front and rear locking members 311, 312, maximizing the strength of the locking effect provided.

As shown in Figure 3E, the locking members 311, 312 project from the face of the panel 310 a length h that is less than the extent of the sidebands 315 such that the sidebands 315 protrude a distance e above the locking members. This ensures that the front to back movement of the panel occurs and the sideband 315 will collide with the guide 330, thereby minimizing the noise generated. This also prevents the locking members from damaging each other when the panels are rolled up, for example as part of a roller door assembly.

As also shown in this example, the stationary locking members 311, 312 (i.e., when the panels are unloaded) typically exit the flanges 331, 332 of the guide 330 a distance d such that at least some lateral movement of the panel ends, The locking members 311, 312 can be adjusted before engaging the respective flanges 331, 332. This helps minimize the noise generated by the application of force to the panel and also helps prevent blockage of the door during use. In one example, the distance d is greater than 5 mm and less than 40 mm, preferably less than 30 mm, the exact distance of which depends on various factors, such as The expected load of the board, the strength of the panel, the intended application, and so on.

As further shown in Figure 3F, the sidebands 315 can be mounted in a variety of different ways. In the present example, the sideband 315 includes a front sideband 315.1 that generally conforms to the front face 310.1 of the panel such that the front sideband 315.1 can follow the peaks and valleys 313, 314 of the panel. Conversely, the trailing side strips 315.2 extend substantially in a straight manner across the rear face 310.2 such that the trailing side strips 315.2 extend between the valleys, which are separated from the underside of the peaks 313. The side straps can be joined in any suitable manner, such as via stitching, riveting, adhesive, or any other suitable fastener.

It should be understood that the above arrangement can be used with the construction of various panels and the exemplary cross-sectional corrugation profile as shown in FIG.

Further, various different guide shapes as shown in FIGS. 5A to 5C can also be used. In the example of Figure 5A, the flange is bent inwardly toward the guide to maximize the retention provided by the flange, while in the example of Figure 5C, a restriction can be provided to prevent the guide from being loaded on the panel. Open under. This function can be accomplished via the formation of a flange, or alternatively via the use of other components, bumps or the like.

It should be understood from the above that in a particular example, the panel is a door panel that forms part of the door assembly. However, this is not intended to be limiting, and in practice the panel may be any form of panel member such as a window, fence, security display panel, or the like.

A further exemplary panel assembly will now be described with reference to Figures 6A through 6C. In the present example, the label addition 300 is used to represent features similar to those shown in Figures 3A through 3D.

In the present example, panel 610 includes front and rear locking members 611, 612 that are actually positioned on adjacent opposing edges of panel 610, in this case only one edge is shown. In this example, panel 610 includes a peak that extends laterally across panel 610. 613 and valley 614, the front locking member 611 projects outwardly from the peak 613 and the rear locking member 612 projects outwardly from the valley 614. As previously mentioned, this maximizes the lateral spacing between the tips of the front locking members 611 and the rear locking members 612, and also maximizes the strength of the locking effect provided.

The front and rear side straps 615.1, 615.2 are mounted on the respective opposite edges, as shown, which are typically formed by stitching the side straps 615.1, 615.2 to the peaks 613, the front sidebands extending generally linearly and bridging the valleys. 614, while the rear sideband 615.2 follows the contour of the back of the panel. This is merely an exemplary purpose and allows for the minimization of the amount of sideband material while simplifying the fixed arrangement, although it will be appreciated that any suitable arrangement may be used.

In this example, reinforcing members 617, 618 are provided between the locking members 611, 612 and respective sides of the panel 610. The reinforcing members are in the form of channels and/or ridges that allow the force F (generated by wind loads or other similar forces) generated along the peaks of the locking members to be dissipated along the length of the edge of the panel rather than concentrating Specific parts on the panel, reducing the possibility of panel failure.

In one example, the reinforcing members are oriented in opposite directions of the locking members, as exemplarily shown in Figure 6C, but alternatively they may be provided in the same direction as shown in Figure 6D. This has the added benefit of increasing the sidebands to ensure that the sidebands protrude beyond the extent of the locking member (i.e., the distance e in Figure 3E is greater than zero).

Exemplary guides are shown in Figures 7A and 7B, wherein the label addition 600 is used to represent features similar to those used in Figure 1C.

In these examples, guide 730 includes a channel 733 and front and rear flanges 731, 732. The guide also includes a surface 734 that allows the guide to be mounted to a wall or other surface, such as in a manner similar to that shown in Figure 1C.

In this example, the channel includes first and second channel portions 735, 736, which are indicated by dashed lines. The first channel portion 735 is wider than the second channel portion 736 to accommodate the panel 710 The range of locking members 711, 712. In this regard, the term "wider" refers to the distance between the front and rear channels 733.1, 733.2. As a result of this arrangement, the positions of the front and rear side bands 715.1, 715.2 are closer to the faces 733.1, 733.2 of the front and rear channels than the locking members 711, 712. This helps to ensure that the front and rear side bands 715.1, 715.2 can abut against the faces 733.1, 733.2 of the front and rear channels when loaded, while also limiting the range of front-to-back motion of the panel.

Additionally, the dimensions of the second channel member are such that even if the locking members 711, 712 are engaged with the flanges 731, 732, at least some of the front and rear side bands 715.1, 715.2 can remain in the second channel portion. Internally, the front to back movement of the panel is limited, which helps to prevent the locking members 711, 712 from being unhooked from the flanges 731, 732.

The guides 730 are typically formed by extrusion of aluminum, but alternatively steel or other suitable materials may be used. The examples of Figures 7A and 7B emphasize the construction in which various different guides can be used, and it should be understood that the arrangement shown is for illustrative purposes and not for purposes of limitation.

For example, the flanges 731, 732 can extend at least partially inwardly to assist in engaging the locking members 711, 712. In the illustrated example, the flanges 731, 732 are aligned with the locking members 711, 712, the position of which is a fixed distance from the edge of the panel 710. In this configuration, the lateral movement of the panel 710 can cause the locking members 711, 712 to engage the flanges 731, 732 at substantially the same time. However, this is not required and any of the locking members 711, 712 or flanges 731, 732 can be offset. This can be performed such that the front locking member 711 and the flange 731 are engaged first before the rear locking member 711 and the flange 732 are engaged, or vice versa. This can be used to provide additional locking strength when the panel is deformed inward or outward, and thus can be used to adjust the desired pressure differential on either side of the panel.

The guide of Figure 7A includes a plurality of voids to help reduce the volume and weight of the material Quantity while maintaining strength. Further, the support members, or support brackets, may be provided at different locations along the length of the guide. This can be performed to strengthen the guide, and in particular prevent the flanges 731, 732 from being pushed apart, which in turn can cause failure of the locking member.

The guide of Figure 7B includes a clip device 738 to allow it to engage a mounting bracket on the wall to facilitate installation, although any suitable mounting device can be used.

Thus, the arrangement described above can provide a panel that can be engaged with the guide to maintain the positioning of the panel, even under adverse lateral load conditions, such as during wind loading. The panel may be fabricated from a lightweight material such as aluminum, steel or the like, and may include an integrated loading member formed by deforming the panel, such as using roll forming techniques. This can result in the panel having a contour that includes corrugations, thereby increasing the strength of the panel, such as a portion of the same process of forming the locking member.

Further features can be provided, such as the sideband absorbing shock, ensuring smooth movement of the panel when the panel is used as a roller door, and a space for the panel when the panel is retracted into the winding configuration. The reinforcing members can be further integrated into the edge of the panel to further enhance the panel's resistance to lateral loads, which can also be formed by deformation of the panel, such that these can also be caused during the manufacturing process.

Throughout this specification and the appended claims, the word "comprise" and its variants such as "comprises" or "comprising" will be used unless the context requires otherwise. It is understood to imply the inclusion of the integer or set of integers or steps, but not the exclusion of any other integer or group of integers.

Those skilled in the art will appreciate that many variations and modifications will become apparent. All such changes and modifications that are obvious to those skilled in the art are considered to be within the broad spirit and scope of the present disclosure.
