Description
A SAW GUIDE DEVICE
Field of the Invention
The present invention relates to a saw guide' device, in particular a device for guiding a saw; more particularly but not exclusively a device for guiding a-sew during cutting of insulation board or'similar:
Background
Many societies across the world increasingly stipulate use of insulation material in building codes and the like.
There are' two main types of insulation, insulation boards and rolls of insulation 15 material, and both need to be cut to size and inserted into an area requiring insulation. *
Insulation boards are typically 'a rigid lightweight foam sandwiched between two covers. In order to provide an effective insulation barrier the boards are generally at 20 least 220mm deep.
CUtting insulation boards in particular can therefore be problematic, given such boards are typically'unwieldy; being large and deep and needinioutting into smaller or awkward or precise shapes.
It can be difficult to cut through a deep board and ensure that the cut is in the right location on the opposing side of the board and/or in a straight line.

It may be 10 envisaged that a stud may be put in a standard hole in the saw end, so as to prevent the sawblade returning through the slot -In some embodiments of the device the device comprises-a:coaxially telescopic body, allowing easy adjustment to suit length or width of the workpiece.
In some suCh embodiments of the device the deviae comprises a bipartite body, for example wherein one pan Slides in another part.
In some such embodiments of the device the device comprises a locking means for 20 telescoping of the body, such that the clamps may be clamped in place and the telescopic body does not compromise the climp. * In some embodiments of the device the body comprises a lacuna in one part adapted to allow passage of a Clamp in the second' Position; such that the retracted body may 25 be minimised Without compromise of the clamp Or damp position.
In some embodiments of the device the bodY is formed of flatpanels; allowing the device to be fit underneath a workpiece without Significant distention or displacement of the workpiece.
In some embodiments of the device the body is aluminium, being lightweight, rigid and inelastic.
In some embodiments of the device the clamps comprise a displaceable attachment 35 means to the body, so as to allow the clamp or clamps to be displaced, removed, replaced or otherwise customisable in positioning or style.
It may be envisaged that in some embodiments one the clamps may be permanently attached to the body, for example comprising a fixed brace or orthogonally extending member, against which the workpiece may be placed.
In some embodiments of the device the attachment means comprises a plurality of locations for attachment of the clamps on the body, so as to allow for adjustment of positioning between clamps to be accomplished via the clamps themselves. For example the clamps may be located in slider rails.
In some embodiments of the device the attachment means comprises threaded fixing, so as to allow tightening and loosening of the attachment with minimal difficulty and with more precision.
In some embodiments of the device the device comprises lateral extensions, for example of or from the body. Such extensions may be envisaged to provide a wider contact with and/or support of the workpiece than the narrow width of the elongate body, so as to allow larger workpieces and/or prevent tipping of the workpiece during cutting.
In some such embodiments of the device the extensions are pivoted to the body, so as to allow them to be retracted or stored when not in use.
According to a further aspect of the present invention there is provided a system of 25 cutting insulation boards using a device according to any of the preceding claims.

Detailed Description of Figures
With reference to the figures there is shown an embodiment of a saw guide device 99 generally comprising an elongate body 21,22 with a longitudinal slot 3 for sawing a workpiece, and one or more clamps 1, wherein the clamps are arranged to extend orthogonally from* the body, wherein the clamps are displaceable from a first proximate position to a second distal position, and whereih the clamp& are adapted to clamp the workpiece ends.
In the pictured embodiment the claims are displaceable through repositioning of the length of the body: In particular reference to the pictured embodiment the embodiment comprises a bipartite body, formed of two elongate planar parts 21,22, wherein an upper part 21 slides on a lower part 22, the upper part an inverted U shaped tray having a small flange parallel the upper face of the body, wherein the lower part of the body is thereby held in place whilst sliding.
The body has plastic caps 15,18 at either end to prevent dislocation of the sliding parts.
The upper part includes a locking means provided by gaps 5 for temporary receipt of 5 resilient tabs 6.
The resilient tabs 6 are sprung with a living hinge, so as to extend upwards from the top face of the lower part of the body 22, such that the tabs 6 fit into the gaps 5 as the upper part of the body 21 is slid over the lower part of the body 22.
The clamps 1 are attached to each of the parts of the body, using bolts 17 passing through fixing holes 7 near the distal ends of the slot, fixing into nuts 16.
The slot continues past the clamps, so as to allow sawing through the ends of the 15 workpiece or board.
The upper part of the body has a lacuna 10 adapted to allow passage of a clamp 1 in the second position, as shown in Figure 3.
* 20 The longitudinal slot extends along the whole body, passing through the upper part and the lower part.
The slot 3 finishes before the ends of the body, and is located offset the central line of the body. The clamp fixing holes 7 are located to the wider section of the body 25 aside the slot.
Two extensions 4 are located 'on the wider section of the body, each pivoted at a pivot 8 to the body. These pivots are located, as can be seen in the retracted body of the embodiment in the second position, as shown in Figure 3, proximate the clamp 30 fixing holes and intermediate the two clamps., The extensions comprise elongated flat members with radiused ends.
The upper part of the body and the lower part of the body are joined together at a 35 sliding joint 9, which is formed with two slider collars 12, extending inwards from the side edges of the body, bonded to the upper part of the body. The collars are formed in self-lubricating Nylon (RTM).
The lower part* 22 has end spacers 13,14, also formed in self-lubricating Nylon 5 (RTM), such that the lower part remains a fixed distance from the undereide of the top face of the upper part Of the body.
The invention has been described by way of examples only and it Will be appreciated that variation may be made to the above-mentioned embodiments without departing 10 from the scope of protection as defined by the claims:
