Abstract

A builders' template tool having four arms 2,4,6,8 interconnected to define a four-sided figure, the arms being connected so to move relative to each other. An extension arm 10 is included, and arms 2 and 4 include as connection which allows rotational adjustment only between arms 2 and 4.

Description

BUILDERS' TOOL The present invention relates to a builders' tool. More
especially the invention relates to a builders' tool for cutting bricks and tiles to specific angles.
It is common during construction of a building for a builder to require bricks that have been cut to a non-standard size and shape. For example, architectural features such as archways and circular patterns in patios require the use of a large number of bricks each cut into an ***.: identical trapezoidal shape. The standard way of cutting a brick to a nonstandard shape requires a builder to measure where the new brick intersects with edges of existing bricks, to rule a line corresponding to the new edge, and to cut the new brick to the desired shape and size using a bolster and hammer. This process can be extremely time-consuming and repetitive, particularly when a large number of non-standard bricks are.. : required.
The applicant's earlier Patent No. 2334783 discloses a builders' template for use with cutting bricks. Whilst the invention disclosed in the patent has proven successful it suffers from certain limitations, most notably in the tasks the tool can perform.
The present invention sets out to provide a unique versatile builder's tool that can perform a variety of functions inter al/a enabling bricks and tiles to be cut efficiently and accurately to desired angles and shapes.
In one aspect, the invention provides a tool comprising four arms, interconnected to define a four-sided figure, a connection between two of the four arms enabling only rotational adjustment between the two connected arms, a connection between two of the four arms enabling only translational adjustment between the two respective arms and the other two connections between the arms enabling both rotational and translational adjustment of the respective connected arms.
Preferably, the tool comprises at least one extension arm is connected to at least one of the four arms of the tool to provide an extension to the arm to which it is connected.
Preferably at least one curved arm is connected between two arms of the tool, the curved arm carrying a graduated scale from which the angle or orientation between said two arms can be calculated. Preferably still, two vertically juxtaposed curved arms are provided, the arms being slidable with respect to each other to reveal the scale.
Preferably, adjustment is enabled by nut and bolt arrangements. *.. * * S ** S
Preferably the bolts are able to slide along an elongate slot formed in one or more of the arms concerned.
The invention will now be described by way of example with reference to the accompanying diagrammatic drawings, in which:- Figure 1 is schematic plan view of a builders' tool constructed in accordance with the present invention Figure 2 is a perspective view of the tool of Figure 1 without an extension arm connected thereto; Figure 3 is a perspective view of one arm of the tool of Figures 1 and 2; Figure 4 is a perspective view of a connecting disc of the tool of Figures 1 and 2; Figure 5 is a perspective view of a further connecting disc of the tool of Figures 1 and 2; Figure 6 is a perspective view from below of a tightening member of the tool of Figures 1 and 2; Figure 7 is a side view of the tightening member of Figure 7; *.....

Figure 10 is a perspective view of an angle indicator of the tool of Figures 1 and 2.
Referring first to Figures 1 and 2, the illustrated builders' tool comprises five arms 2, 4, 6, 8 and 10. Each arm is formed from a lightweight flexible but strong material such as, for example, glassfilled nylon. Other suitable plastics material or metallic material, for example, aluminium or steel may alternatively be used.
The arms 2,4,6,8,10 are interconnected to define a four-sided figure.
By way of example, a suitable width of each arm is 25 mm and a suitable thickness is 8 mm. As can be seen from Figure 3, each arm has bevelled sides for aesthetic appeal and also for increased strength.
Each arm is formed with a longitudinal slot 2a, 4a, 6a, 8a and lOa respectively.
Each arm 2, 4, 6, 8, 10 carries a graduated scale alongside the slots 2a, 4a, 6a, 8a, iDa, calibrated for example in standard units or fractions of standard brick dimensions, or both. The scale is preferably laser engraved or etched into the arm material to withstand wear and tear in site conditions. Each arm 2, 4, 6, 8, 10 is preferably coloured yellow, as tends to be standard in the building trade, with a dark scale. Clearly, however, any other colour for the arms or the scale may be used.

Figure 3 illustrates a first arm 2 of the tool. This arm 2 has a circular aperture 12 formed near one end 13. A second arm 4 is connected to the first arm 2 via a first connecting member 14a which is described later in detail. S... * S *5*S
The connecting member 14a extends through the slot 4a of the *: second arm 4 and the aperture 12 of the first arm 2 thereby to allow only rotational adjustment of first and second arms 2, 4 with respect to each other.
A third arm 6 is connected to the first arm 2 to one side of the first connecting member 14a. The arms 2, 6 are connected together via a second connecting member 14b which extends through the slot 2a of the first arm 2 and the slot 6a of the third arm 6. Such connection allows both rotational and translational adjustment of the first and third arms 2, 6 with respect to each other.
Respective ends of a fourth arm 8 are connected to the second arm 4 and the third arm 6 respectively via third and fourth connecting members 14c, 14d. The third connecting member 14c extend through the slot 8a of the fourth arm 8 and the slot 4a the second arm 4. Such connection allows both rotational and translational adjustment of the second and fourth arms 4, 8 with respect to each other.
The fourth connecting member 14d extends through the slot 8a of the fourth arm 8 and the slot 6a of the third arm 6, and through a first connecting disc 16 (see Figure 4) located between the third and fourth arms 6, 8 at the connection point. The disc 16 is shaped to prevent rotational adjustment of the third and fourth arms 6, 8 with respect to each other. Thus, the overall connection allows only translational adjustment of the third and fourth arms 6, 8 with respect to each other.
In other words, the third and fourths arms 6, 8 always remain at right angles to one another. * ** *
A fifth arm 10 is connected to the second arm 4 via a fifth connecting member 14e which extends through the slot lOa of the fifth S..
arm 10 and the slot 4a of the second arm 4, and through a second connecting disc 18 (see Figure 5) located between the second and fifth *: arms 4, 10 at the connection point. The disc 18 is shaped to prevent rotational adjustment of the second and fifth arms 4, 10 with respect to each other. Thus, the overall connection allows only translational adjustment of the second and fifth arms 4, 10 with respect to each other.
In other words, the second and fifth arms 4, 10 always lie along the same longitudinal axis such that the fifth arm 10 acts as an extension to the second arm 4 if required.
Further arms can be connected to any of the arms of the tool in the same manner to extend the size and therefore the potential use of the tool.
The first connecting disc 16 is illustrated in Figure 4. This disc comprises a flat circular base 20 having a first protrusion 22 mounted or otherwise formed on the top surface of the base 20. The protrusion 22 is rectangular in shape and extends laterally from the centre of the base 20 to a point beyond its circumference. The width of the protrusion 22 corresponds to the width of the slot 8c of the fourth arm 8. During construction the disc 16 is located underneath the arm 8 (between the arm 8 and the third arm 6) whereby the protrusion extends upwardly into the slot 8c. The disc 16 is therefore able to slide along the length of the slot 8c.
Mounted or otherwise formed on the opposite surface of the base is a second protrusion 24. This protrusion 24 is also rectangular in shape and extends laterally from the centre of the base 20 to a point I.....
beyond its circumference, perpendicularly to the first protrusion 22. The width of the protrusion 24 corresponds to the width of the slot 6c of the third arm 6. During construction the disc 16 is located above the arm 6..
(between the arm 6 and the fourth arm 8) whereby the protrusion 22 extends downwardly into the slot 6c. The disc 16 is therefore able to slide along the length of the slot 6c. S... * . . S. *
The presence of the disc 16 prevents rotational movement of the third and fourth arms 6, 8 with respect to each other while allowing translational movement of the arms with respect to each other in either direction.
The second connecting disc 18 is illustrated in Figure 5. This disc comprises a flat circular base 26 having a first protrusion 28 mounted or otherwise formed on the top surface of the base 26. The protrusion 28 is rectangular in shape and extends laterally from the centre of the base 26 to a point beyond its circumference. The width of the protrusion 28 corresponds to the width of the slot 4c of the second arm 4. During construction, the disc 18 is located underneath the arm 4 (between the arm 4 and the fifth arm 10) whereby the protrusion 28 extends upwardly into the slot 4c. The disc 18 is therefore able to slide along the length of the slot 4c.
Mounted or otherwise formed on the opposite surface of the base 26 is a second protrusion 30. This protrusion 30 is also rectangular in shape and extends laterally from the centre of the base to a point beyond its circumference, along the same longitudinal axis as the first protrusion 28. The width of the protrusion 30 corresponds to the width of the slot lOc of the fifth arm 10. During construction, the disc 18 is located above the arm 10 (between the arm 10 and the second arm 4) whereby the protrusion extends downwardly into the slot lOc. The disc 18 is therefore able to slide along the length of the slot lOc. *

direction. I...
Figures 6 and 7 illustrate the connecting members 14a-e. Each **** connecting member comprises a nut part 32 and a bolt part (not shown). .. : The nut part 32 comprises a gripping surface 34 and a circular recess 36 with an internal thread for receiving the bolt part. A brass washer 38 surrounds the entrance to the recess 36. The gripping surface 34 is generally dome-shaped and has two concave indentations 40 to improve the ability for a use to grip and turn the nut part 32. The brass washer 38 further improves the connection between the nut part 32 and bolt part during use. The connecting members 14a-e connect respective arms together by placing the arms, and if required a connecting disc, between the nut part 32 and bolt part of the connecting member and turning the nut part 32 until the two arms are secured together at required positions along their slots.
The nut part 32 can be loosened from the bolt part by turning, to allow adjustment of the connecting point of the associated arms, whether it be through relative rotational movement, translational movement or both.
Figures 8 and 9 illustrate a spirit level 40 that can be attached to an arm of the tool to allow the user to ascertain whether the respective arm is horizontal or vertical during use.
The spirit level 40 has an outer casing 42 each end of which included a downwardly extending protrusion 44. The protrusions 44 are generally rectangular in shape and have a width that corresponds to the width of the slots 2a-lOa of the arms 2-10. The spirit level 40 can be attached to a generally horizontal arm of the tool, for example the fourth S..,..
arm 8, by pushing the protrusions 44 of the casing 42 into the slot 8a of the arm 8. Once attached, the spirit level 40 is able to inform the user of the tool whether or not the arm 8 is indeed horizontal and, by virtue of..
the connection between the fourth arm 8 and the third arm 6, whether the third arm 6 is vertical. * S S... S...
Each side of the casing 42 of the spirit level has an arm 46..
extending outwardly therefrom. Each arm 46 ends in a downwardly extending protrusion 46a, 46b, the widths of which also correspond to the width of the slots 2a-lOa of the arms 2-10. The spirit level 40 can therefore also be attached to a generally vertical arm of the tool, for example the second arm 4, by pushing the protrusions 46 of the casing 42 into the slot 4a of the arm 4. Once attached, the spirit level 40 is able to inform the user of the tool whether or not the arm 4 is vertical or at a required angle to the vertical.
Two spirit levels 40 could, of course, be used with the tool to determine horizontal and vertical orientation at the same time.
Alternatively, each arm may have its own spirit level attached thereto.
Referring now to Figure 10, a first arcuately curved arm 48 is connected via a sixth connecting member 14f to the first tool arm 2. A second similarly curved arm 50 overlies the first curved arm 48. The second curved arm is connected via a seventh connecting member 14g to the second tool arm 4.
Although not shown in Figure 10, the first curved arm 48 carries a graduated scale of angles which correspond to the relative orientation between the first and second tool arms 2, 4. During use, as the second arm 4 is pivoted away from the first arm 2, the second (top) curved arm slides along the first (bottom) curved arm 48 thereby revealing the angle of orientation displayed on the first curved arm 48. Similarly, as the first arm 2 is pivoted away from the second arm 4, the first curved S's.,.
arm 48 slides from under the second curved arm 50 to reveal the angle of orientation between the two arms.
S * i.
Once the two arms 2, 4 have been moved relative to each other to the desired angle, the first connecting member 14a is tightened to secure *4*5 the arms 2, 4 in that position. **** * S. *
On way to use the tool of the present invention will now be described. Measurements are made on a brick and checked carefully.
The tool is then laid over the brick with the connecting members 14a-g loosened and the arms 2-lOa positioned adjacent the newly cut edges of the brick. The connecting members 14a-g are then tightened, fixing the tool into the intended shape.
The tool is then lifted from the first brick and applied to an uncut brick. The tool is positioned over the brick in the same relative position and a marking implement such as a pencil is used to mark the necessary cuts on the surface of the brick. The brick is then cut in the normal way.
The ability to ensure that all the arms of the tool are capable of be positioned to precise angles and orientation allows the tool to be used as a template in many areas of building where such precise measurements and angles are crucial.
The above described embodiment has been given by way of example only, and the skilled reader will naturally appreciate that many variations could be made thereto without departing from the scope of the present invention. * I
