## Background
CROSS REFERENCE TO RELATED APPLICATION
This application is a continuation-in-part of International Application No. PCT/AU2015/000115, filed Feb. 27, 2015, which claims the benefit of Australian Patent Application No. 2014900789 filed on Mar. 7, 2014, the disclosures of which are incorporated herein in their entirety by reference.


TECHNICAL FIELD
The present invention relates to tools fastening or loosing nuts.
The invention has been devised particularly, although not necessarily solely, in relation to a wrench and socket for fastening or loosing nuts. More particularly, the invention relates to a basin wrench and socket.
BACKGROUND ART
The following discussion of the background art is intended to facilitate an understanding of the present invention only. The discussion is not an acknowledgement or admission that any of the material referred to is or was part of the common general knowledge as at the priority date of the application.
Replacing an old faucet is typically a cumbersome and time consuming task. This is particularly true in view that locking nuts that hold the old faucet to the basin need to be removed. Removal of the nuts can be cumbersome and time consuming because typically the basin nuts are frozen to the thread of the faucets due to corrosion or mineral buildup from years of water seepage.
Moreover, removal of the basin nuts can also be cumbersome because the nuts are located in areas of reduced space located in the lower portion of the basin. These areas of reduced space are formed due the bowl or bowls that are formed in the basins for holding of liquids for washing purpose.
Furthermore, in particular removal of spouts (see FIG. 5b) from basins can be a greater challenge than removing, for example, pillar taps. This is because typically water mixers include piping located below the nut to be removed. This piping restricts accessing the nut with conventional tools. Tools have been designed to remove basin nuts under these particular circumstances. For example, adjustable basin wrenches are available. However these wrenches are typically too bulky and; thus, in most cases these tools cannot be used.
It is against this background that the present invention has been developed.

DESCRIPTION OF EMBODIMENT(S)
FIGS. 1 to 4 show a first arrangement of a tool 10 in accordance with an embodiment of the invention. The tool 10 is adapted to loosen or fasten connector nuts 40 located in areas of reduced space. The tool 10 is particularly useful because it allows manipulating basin nuts 40 located between the lower portion of the basing and piping that provides water to the faucets that are attached to the basin via the nut 40—see FIGS. 5a and 5b and FIGS. 7a to 7e. 
FIG. 1 shows a side view of the tool 10. The tool 10 comprises a body 12. The body 12 comprises a distal section 14 (the first section) and a proximal section 16 (the second section). The distal section 14 and the proximal section 16 are joined together via two centre sections 18 (the third section) opposite with respect to each other to define clearances 24a and 24b (the first clearances)—see for example 24b. The width of each centre section 18 defines the size of the clearances 24a and 24b. As will be explained at a later stage, the particular size of the clearances 24a and 24b facilitates fastening and loosening of the nuts 40.
The fact that the distal section 14 is separated from the proximal section 16 defines a clearance 20 (the second clearance) between the distal and proximal section 14 and 16. The clearance 20 is adapted to receive the piping 28. As will be explained with reference to the method of operation of the tool 10, the clearance 20 allows rotation of the tool 10 during application of the torque to the connector nut 40 for loosening or fastening of the connector nut 40. In an arrangement, the clearance 20 may be about between 34 mm to 54 mm long.
Referring now to FIGS. 2a and 2b and FIGS. 3a and 3b, in the particular arrangement shown in the figures, the distal section 14 comprises a plurality of gripping means 22. The gripping means 22 are arranged in an opposite relationship with respect to each other to allow releasably grabbing a connector nut 40.
Referring in particular to FIGS. 2a and 3a, each gripping means 22 are configured for releasably grabbing a connector nut 40. In the particular arrangement shown in the figures each gripping means 22 comprises a centre section 50 and two side sections 52 and 54. The side sections 52 and 54 extend diagonally outward from the centre section 50 defining a substantially U-shaped section—see FIG. 3a. This particular arrangement of the gripping means 22 is adapted to receive connector nuts 40 of a variety of different configurations such as, for example, hexagonal shaped nuts 40. In alternative arrangements of the present embodiments the gripping means 22 may be configured in such a manner that other type of nuts may be fastened or loosened with help of the present tool 10.
Further, the fact that the distal section 14 comprises a plurality of gripping means 22 that are opposite with respect to each other defines a plurality of first clearances 24a and 24b—see FIG. 3. As will be explained with reference to the method of operation of the tool 10, the first clearances 24 allows piping 28 to be located adjacent to the proximal section 16—see FIG. 5.
Further, the centre section 18 comprises a plurality of supports 26a and 26b. Each support 26 joins one of the gripping means 22 of the distal section 14 to the proximal section 16. In the particular arrangement shown in the figures, the supports 26 are of a reduced width with respect to the gripping means 22. As will be explained with reference to the method of operation of the tool 10, the reduced width of the supports 26 facilitates turning of the tool during manipulation (for example, loosening or fastening) of the nut.
We refer now to FIGS. 2b and 3b. 
It was mentioned that the tool 10 comprises a proximal section 16 to which the distal section 14 of the tool 10 is joined via the centre section 18. This proximal section 16 is adapted to receive torque for delivery to the distal section 14 during fastening or loosing of the nut 40. In a particular arrangement, the proximal section 16 comprises a first end 32 and a second end 34. The first end 32 is attached to the centre section 18 to which the distal section 14 is attached. The second end 34 is adapted for attachment of a tool to apply torque to the proximal section 16. As shown, in FIG. 2b, the second end 34 comprises an opening 30 adapted to receive, for example, a square fitting 56 (see FIGS. 6a and 6b) that is attached to a tool such as a handle or ratchet. In this manner, torque may be applied to the tool 10 for either loosening or fastening a nut 40 such as a basin nut 40.
As an example, FIGS. 6a and 6b shows a tool 10 in accordance with a particular arrangement. In this particular arrangement, the tool 10 comprises a T-handle 36 attached thereto. The T-handle 36 may be of variable size and/or may include a plurality of bars pivotally attached to each other defining elbows to orient the handle 36 at different angles with respect to the longitudinal axis of the tool 10.
In an alternative arrangement, the tool 10 may be configured as a socket. The first end 32 of the socket is adapted to receive the distal section 14 of the tool 10 and the second end 34 is adapted to receive the square fitting 56 to allow releasably attaching the previously described T-handle 36. The socket may be adapted to receive a square fitting of a wrench such as, for example, a ratchet.
FIG. 5a shows the tool 10 in use. In this arrangement, the tool 10 is used for loosening or fastening of a nut 40 that attaches a faucet 42 to a countertop 44. As shown in FIG. 5b, the nut 40 is located between the countertop 44 and the piping 28. As can be appreciated from FIG. 5b, the piping 40 hinders accessing the nut 40 by a conventional tool, such as a conventional socket which are typically used for applying torque to nuts.
We refer now to FIGS. 7a to 7e. 
In operation, as shown in FIG. 7b the tool 10 is approached towards the lower portion of the counter top 44 such that the nut 40 may be located between the gripping means 22—see FIG. 7d. The nut 40 can be located between the gripping means 22 because the distal section 14 comprises the clearances 24 that allows the piping 28 to traverse the distal section 14 of the tool 10 to locate the piping 28 adjacent the first end 32 of the tool 10. At this stage, the user may apply torque to the nut 40 for either fastening or loosening of the nut 40 during attachment or detachment from the countertop 44. The tool 10 is able to rotate and thus applying the torque to the nut 40 due to fact that the centre section 18 is of a reduced width with respect to the gripping means 22 defining the clearances 24.
Referring to FIG. 7e, the nut 40 may be fastened or loosened by continually applying torque to the nut 40 using the tool 10. This is accomplished by (1) attaching the tool 10 to the nut 40 and turning the tool 10 until the centre sections 18 reaches the tubing 28 (see FIG. 7e), and (2) releasing the tool 10 from the nut 40 as shown in FIG. 7e and repeating step (1). For fastening or loosening the nut 40, these two steps may be continuously repeated until the nut 40 has been fastened or loosened.
We refer now back to FIG. 2. The particular arrangement shown in these figures show a plurality of ribs 60 spaced apart with respect to each other. The ribs 60 extend from the distal section 14 to the proximal section 16 of the tool 10. It is particularly advantageous that the toll comprises the ribs 60. This is because one of the advantages of the inclusion of the ribs 60 is that it reinforces the centre section 18. In this manner, the centre section 18 may be of relative small width.
Furthermore, it was mentioned earlier that the fact that the centre section 18 may be of a reduced width with respect to the gripping means 22 provides a plurality of clearances 24a and 24b. The size of the clearance 24a and 24b will determine the amount that the tool 10 may be turned during fastening or loosening of the nut 40. In accordance with the present embodiment of the invention, the width of the centre section 18 of a particular tool (in accordance with the present embodiment of the invention) may differ with respect to each other; in this manner, different tools 10 may be used for different faucets 42 differing in the type of tubing or the tubing arrangement located below the countertop 44.
In a particular arrangement, each centre section 18 has a width of about between 9.6 to 15.5 mm defining the two first clearances 24.
In a particular arrangement, the two first clearances have a size of about 26.1 mm to about 32.4 mm.
In other arrangements, the two first clearances taper as they extend from the first section to the second section, their size being between about 26.1 to 32.4 mm at the first section and reducing to 24.6 to 30.6 mm at the second section.
In a particular arrangement, the distance between the distal section 14 and the proximal section 16 (that define the second clearance 20) has a length between about 34 mm to 54 mm.
Furthermore, the above described arrangement of the tool 10 is configured for use in connection to conventional nuts such as hexagonal nuts. However, the tool 10 may be configured to accept connector nuts 40 of varied configurations and sizes.
For example, in a second arrangement of the tool 10 may be configured for receiving a faucet stem retention nut 66 of the type having wings 68 to facilitate rotation as shown in FIG. 9a. 
FIG. 8 shows this particular second arrangement of the tool 10. As shown in FIG. 8, the tool 10 in accordance the second arrangement comprises an indentation 62 extending into the distal end 14 of the tool 10. The indentation 62 is adapted to receive the wings 68—see FIG. 9b. 
Modifications and variations as would be apparent to a skilled addressee are deemed to be within the scope of the present invention.
Further, it should be appreciated that the scope of the invention is not limited to the scope of the embodiments disclosed. By way of example, the arrangement of the figures shows the plurality of gripping means 22 defining a hexagonal head adapted to apply torque to a hexagonal nut. However, the distal section may be configured to define any of shape so as to receive any type of nut.
Moreover, the centre section 18 has been described as having a particular fixed length. However, alternative arrangement of the tool 10, may include centre sections 18 of different fixed lengths. In a further particular arrangement, the centre section 18 of a particular tool may be adapted for varying is particular length.
In an arrangement, a particular embodiment of the invention may provide a kit comprising a plurality of sockets having heads of different shapes so as to loosen or fasten different type of nuts. For example, in an alternative arrangement of the present embodiment of the invention may include a double hex design such as a 12 pointed socket. In a particular arrangement, two of the points may be removed to allow a greater range of rotary movement during fastening or loosening of the nut 40.
Also, the sockets included in the kit may include centre sections 18 of different lengths and different width. This kit is particular useful because it allows handling a plurality of different configurations of faucets and nuts attached to different type of countertops 44.
In further embodiment of the invention there may be provided a tool 10 wherein the length of the centre section 18 may be variable to accommodate the various requirements depending on the type of applications for which the tool 10 is to be used.
Furthermore, the distal section 14 may be releasably attached to the proximal section 16. For example, in a the particular arrangement, the toll 10 may incorporate proximal sections that are adapted to releasably attaching the centre section so as to releasably attaching the distal section 14 to the proximal section 16.
Throughout the specification and claims, unless the context requires otherwise, the word “comprise” or variations such as “comprises” or “comprising”, will be understood to imply the inclusion of a stated integer or group of integers but not the exclusion of any other integer or group of integers.
