Abstract
For many years windows and doors have been fitted to building frames with packers, to
avoid having to adjust frames to suit the finished size of a pre-assembled door or window.
Making individual packers is time consuming, and assembling packers from sets of thin
5 packers can be difficult or wasteful of materials. The present invention seeks to solve this
problem using complimentary shaped wedged packers that can be assembled with ease,
and which can be adjusted with equal ease to produce a desired packer size. The design
also allows any excess size to be quickly removed. Details in the design of the
construction packer assemblies of the present invention provide for incremental thickness
10 adjustment and an assembly that remains assembled during thickness adjustment. The
design also reduces any chance of packers slipping after the door or window has been
installed.

Construction Packers and Construction Packer Assemblies
This invention relates to construction packers, and in particular, but not exclusively to construction packers and packer assemblies for use in house construction when fitting windows and doors.
When fitting windows and doors to the frame of a house or similar building, there is generally a requirement to install packers between the opening in the framework of the house and the frame of the doorway or window.
The size and shape of door and window modules are generally dimensionally accurate, and rectangular in shape. The openings formed in building frames are typically not quite so accurate. For this reason the openings are constructed a little larger than the door or window module that is to be fitted into the opening, and packers are used to make up the difference.
Packers have a number of additional uses in the building trade, for example, packing kitchen cabinets to make them level, packing out a pre-nailed frame to make it vertical, etc.
The size of the packers required will almost always vary. And the thickness of the packers must be carefully adjusted or chosen by the installer to ensure that the window or door module is fitted snugly and plumb, or to suit whatever application the packer is being used in.
The production of the packers, or the adjustment and fitting of the packers, can be a time consuming task. The task often involves a trial fit of the window or door, taking measurements at various locations around the window or door frame, then removing the window or door, then making or assembling packers, and then fitting the door or window into the opening with the packers. Nails or screws are fitting through the door or window
207057AU 8 Nov 2022_DESCRIPTIONCLEAN AMD.DOC from and the packers to hold the packers securely, and to secure the door or window in place.
Sets of packers of various sizes are available, but these can be time consuming and fiddly to assemble to the required thickness, and are often cumbersome to install, and are not easily adjusted during the fitment process. Also, the sets usually result in significant wastage of product as a significant proportion of each set often ends up as scrap.
During the installation process it is not uncommon for a packer to fall out while other packers are being fastened in place.
Also, it is not uncommon to need to adjust the thickness of one or more of the packers, or to fit some of them after fitting the door or window into the opening. This can lead to the misplacement, or tearing, of waterproof membranes or tapes that are fitted to the openings of the building framework.
Wooden packers or wedges have been used in the past, but these are prone to rotting if properly treated timber is not used.
In summary, the production, or fitting of packers in the construction industry is often time consuming or difficult, results in significant wastage, results in damaged waterproofing membranes, or rotten packers over a period of time. There has to be a better way.

With reference to Figures 1 to 6, a construction packer assembly (11) according to the present invention will now be described. The construction packer assemblies (11) have been designed for use in the construction of buildings, and particularly for use in fitting window modules and door frames to openings in the structure or frames of buildings. The construction packer assemblies (11) can also be used in a variety of other applications, for example in helping to get kitchen modules level, or to straighten or re-align a part of the building structure.
The construction packer assembly (11) comprises a first member (13) and a second member (15). Both are configured for use together, and together they form the packer assembly (11) which has an adjustable thickness. A feature of the construction packer assembly (11) is that its thickness can be adjusted in-situ. The packer, or the window or door frame, etc, no longer needs to be removed to make adjustments.
207057AU 8 Nov 2022_DESCRIPTIONCLEAN AMD.DOC
The first member (13) and the second member (15) are each made of a plastics material, and the second member (15) is approximately twice as long as the first member (13). Both the first member (13) and the second member (15) have provisions in the form of holes (16) for passing a mechanical fastener such as a nail or screw through them to fix them in place. In this example, the first member (13) has a single hole (16) and the second member (15) has two holes (16).
The first member (13) and the second member (15) each have a first face and a second face. The first face (17) of the first member (13) is the face shown in Figure 3d, and this face (17) defines a first plane (19). The first face (21) of the second member (15) is that shown in Figure 4a, and this face (21) defines a second plane (23). When the construction packer assembly (11) is assembled, the first plane (19) is substantially parallel to the second plane (23).
The second face (25) of the first member (13) is the face shown in Figure 3a, and this face (25) has engagement features that are configured to engage with complimentary engagement features of the second face (27) of the second member (15). The engagement features engage in such a manner that the first member (13) is prevented from moving relative to the second member (15) in a first or sideways direction (29) which is substantially parallel to the first plane (19), while allowing movement of the first member (13) relative to the second member (15) in a second or longitudinal direction (31). The first direction (29) is substantially at right angles to the second direction (31).
It can be seen in the Figures that the first member (13) and the second member (15) are each substantially wedge shaped members. When assembled, a thin end (33) of the second member (15) can be placed substantially over a thick end (35) of the first member (13), and the two members (13) and (15) are pressed together. Then, movement of the first member (13) relative to the second member (15) in the second direction (31) provides the thickness adjustment of the construction packer assembly (11).
In this example, the complimentary engagement features include a number of tongues (37) that are sized to have an interference fit with a number of complimentary grooves (39) on the second faces (25) and (27). A slight interference fit between the first and the second members (13) and (15) is beneficial in that the two members are held together
207057AU 8 Nov 2022_DESCRIPTIONCLEAN AMD.DOC during the installation process. For example, the first members (13) can be nailed or screwed to the opening for a window as shown in Figure 6, and then the second members (15) can be fitted to, and engaged with, the first members (13) and they will hold together while the window is fitted into the opening.
The interference fit can be used to hold the assembly (11) together during installation, and the engaged tongues (37) and grooves (39) prevent sideways movement of the second members (15) relative to the first members (13) during thickness adjustment and during the life of the building in which the assemblies (11) are fitted.
In this example the tongue and groove arrangement also includes features or detents configured to facilitate incremental adjustments of the location of the second packer (15) relative to the first packer (13) in the second direction (31). These features are in the form of complimentary fine wave or rib formations (41) - refer to Figures 4b and 4c. The wave formations (41) are formed on the outer face of each tongue (37) and on the inner face of each groove (39). The crests of the wave formations (41) run transversely across each outer face of a tongue (37) and each inner face of a groove (39).
When the second member (15) is pushed onto the first member (13), the complimentary wave formations (41) engage. When under pressure, for example when the assembly (11) is in-situ, and adjusted to bear against a window or door frame, the engaged wave formations (41) will help to hold the second member (15) relative to the first member (13) and to prevent slippage in the second direction (31). During installation the wave formations allow controlled, detented or incremental movement of the second member (15) relative to the first member (13).
In this example, the angle of each shallow wedge shape is approximately three to four degrees, or to be more precise is approximately 3.3 degrees. The pitch of the wave formations or detents (41) is approximately one millimetre and the depth of each wave is approximately 0.3 millimetres. A single incremental movement of the second member (15) relative to the first member (13), that is movement in the second direction by the pitch of one wave formation (one millimetre), will give a 0.071 millimetre change in the thickness of the assembly (11).
207057AU 8 Nov 2022_DESCRIPTIONCLEAN AMD.DOC
It can be seen in Figure 3d that the first face (17) of thefirst member (13) has a first contact surface (43) lying in the first plane (19). Similarly, in Figure 4a it can be seen that the first face (21) of the second member (15) has a number of second contact surfaces (45) all lying in the second plane (23). The first face (17) and (21) of each first and second member, or at least the contact surfaces (43) and (45), are configured to bear against either a part of the structure of a building or an item being fitted to the structure of the building.
In this example, the second member (15) includes multiple in the form of relatively deep slots running transversely across its width. In practice, second members (15) that are 130 to 150 millimetres long have been used, and they have nine to eleven lines of weakness (47). The lines of weakness (47) are ideally spaced about eight to twelve millimetres apart, and in the example shown are ten millimetres apart. The last forty millimetres of the thin end of the second member (15) does not have any lines of weakness. The lines of weakness (47) are configured to any allow excess length (49) of the second member (15) to be snapped off as shown in Figure 6.
When used, a number of the first members (13) will be installed onto the facing surfaces of the framing timbers defining a window or door opening. A sloping 'lead-in' face (51) at the thick end (35) of the first member (13) is helpful in guiding a forward edge of a window or door reveal (53) into the window or door opening. The sloping 'lead-in' face (51) is ideally at an angle of between twenty and fifty degrees to the first plane (19), and in the example show the angle is approximately twenty seven degrees.
The construction packer assembly (11) enables a new method to be employed when fitting an object such as a window or door frame to the structure of a building. The new method includes the steps of;
• fastening one or more first members (13) of the construction packer assembly (11) to the structure of the building,
* fitting the object into the structure of the building,
• engaging a second member (15) with the or each first member (13), and
207057AU 8 Nov 2022_DESCRIPTIONCLEAN AMD.DOC adjusting the thickness of the or each construction packer assembly (11) as required.
The step of adjusting the thickness of the or each construction packer assembly (11) generally involves pushing or tapping the second member to move the second member relative to the first member.
After the thickness adjustment, the method is generally completed by passing one or more mechanical fasteners (nails or screws) through the door or window reveal and the construction packer assembly (11), and into the building framework, to permanently fix the window or door. And then, any excess length (49) in any of the first or second members (13) or (15), can be broken off with a clout from a hammer, or by cutting with a sharp chisel.
Aspects of the present invention have been described by way of example only and it should be appreciated that modifications and additions may be made thereto without departing from the scope thereof.
The example described above refers to the assembly of a first member (13) and a second member (15). It is envisaged that in practice, the construction packer assembly (11) could alternatively comprise two first members (13), or two second members (15), mated together to suit a particular application.
In the example described herein, the assembly includes a number of features, that is, tongues and grooves, having an interference fit there-between. It is envisaged that in an alternative embodiment a single complimentary features could provide a single area of interference fit.
Similarly, the example described herein includes a number of complimentary tongues and grooves, and it is envisaged that even a single tongue and groove arrangement would suffice.
207057AU 8 Nov 2022DESCRIPTIONCLEAN AMD.DOC
In the example described herein, the first member (13) has one contact surface (43), and the second member (15) has a number of contact surfaces (45). It is envisaged that either member (13) or (15) could have one or more contact surfaces (43) and (45).
Also, in the example described herein, the incremental adjustment was facilitated by complimentary fine wave formations (41). It is envisaged that in an alternative embodiment the wave formations could be replaced by notched, zigzagged, or toothed formations, etc.
In the example described herein, only the second member includes multiple lines of weakness (47). It is envisaged that in an alternative embodiment, both members (13) and (15) could include multiple lines of weakness (47), or neither.
Throughout this specification the word "comprise" and variations of that word, such as "comprises" and "comprising", are not intended to exclude other additives, components, integers or steps.
Thus it can be seen that at least the preferred form of the invention provides a construction packer assembly which provides advantages over the prior art in one or more of the following areas;
• improved ease in making adjustments to packer thickness,
* improved ease in assembling and installing packers,
* reduction in time taken to fit a door frame or window,
• reduced chance of packer slippage during and after installation.
207057AU 8 Nov 2022_DESCRIPTIONCLEAN AMD.DOC
• less chance of damaging the window or door frame during fitment,
* less chance of damaging any waterproof membranes fitted to the opening where the window or door is being fitted,
* less wastage of packer material, and/or
• improved life or durability of the packer.
