Description

[01] The present invention relates to a receptacle for a spirit level, straight edge tool or other hand tool. Background of the Invention

[02] A spirit level is an everyday item and designed to indicate whether a surface is horizontal or vertical. A spirit level typically includes a curved glass vial filled with a liquid (such as alcohol). The position of an air bubble in the liquid in the vial determines whether or not the surface is perfectly level. In the building trade, particularly in construction, spirit levels are an essential tool. They are typically provided in the form of a robust elongated stick containing at least one of the curved glass vials. A problem with spirit levels is that they can be expensive, cumbersome and bulky. When temporarily not in use at a worksite, spirit levels are typically leant up against walls, placed on the ground or on another surface (which may unstable or uneven). Where a spirit level is placed can lead to accidents or damage at the worksite and / or damage or breakage to the spirit level (particularly the glass vial). There have been multiple occasions where this has occurred, for example, a spirit level placed against a painted wall which has slipped and damaged the wall, a spirit level placed on a surface where it has been knocked off breaking a glass window and a spirit level being bumped, hitting and injuring a tradesman. Another problem is that sometimes tradesmen forget where they placed the spirit level or place it in a place which not readily accessible, for example, a vehicle parked off-site. Many of these problems also apply to straight edge tools and other hand tools.

[03] It would be desirable to provide a device which allows a spirit level, straight edge tool or other hand tool to be temporarily housed at a worksite while it is in use and enabling it to be readily accessible, or provide a suitable alternative.

[16] The present invention relates to a receptacle in which at least a portion of a spirit level, straight edge tool or other hand tool is seated.

[17] In one or more embodiments the spirit level is suitably any spirit level used in the building and / or construction industry such as an i-beam (girder) level, box beam level, torpedo level or scaffold level. In one or more embodiments the straight edge tool is a ruler, block plane or square and suitably similar in size to a spirit level but typically longer. In one or more embodiments the other hand tool is one or more of an awl, broom, chisel, file, gimlet, hammer, knifes, mallet, pincers, pliers, punch, rake, rasp, ratchet, screwdriver, saw, scissors, snip, spanner, or wrench or other suitable tool such as any tool with a seatable portion. In one or more embodiments the spirit level or straightedge tool suitably has a rectangular cross-section, although the receptacle can be modified to accommodate any spirit level..

[18] The receptacle suitably includes a body having a base and an upper surface, the upper surface including an opening for receiving the spirit level and providing access to an internal space provided in the body for seating at least a portion of the spirit level. The body is a semi sphere or dome shape. In one or more embodiments the body is suitably weighted towards the base. In one or more embodiments the body includes a solid base. In one or more embodiments approximately 40 to 60 percent or more (for example 40,45,50, 55 or 60 percent) of the total weight of the receptacle is distributed at the base to ensure stability. In one or more embodiments the body suitably includes a rebated handle. In one or more embodiments the rebated handle includes lip defining a recessed -2- 09 01 25 portion suitably for accommodating a finger or thumb. In or more embodiments the base includes a substantially flat portion (suitably for resting or sitting flat on a level surface), although the base can be designed so that it will sit on a non-flat surface if required. The receptacle body, suitably the base, includes one or more recesses or mounts for seating or mounting one or more wheels, typically a roller wheel. Provision of at least one wheel in the receptacle body / base suitably enables the receptacle (containing or not containing the spirit level) to be rocked onto the wheel(s) and moved within and outside the worksite.

[19] The opening and / or internal space has a shape complementary to the spirit level to be seated. For example suitably the opening has a shape which substantially matches a cross-section of the portion of the spirit level to be seated in the receptacle. In one or more embodiments the opening is suitably rectangular in shape. In one or more embodiments the internal space is suitably a channel or passageway. Suitably the internal space has a shape which substantially matches the portion of the spirit level to be seated in the receptacle. In one or more embodiments the internal space has a rectangular shape. In one or more embodiments the opening in the upper surface is located opposite the base and the channel or passageway is directed substantially vertically from the opening towards the base (it will be appreciated that the channel or passageway could also be angled from the opening if desired - particularly if the opening is not centred in the upper surface). The opening to the internal space is provided with a threaded rod and stop end which can be manipulated (suitably by turning) to close the gap in the opening, the stop end suitably abutting against the spirit level / straight edge tool and suitably thereby keeping the spirit level / straight edge tool as upright as possible.

[20] In one or more embodiments the receptacle may be made from any suitable material including clay, glass, rubber, elastomers, metal, plastic (including photopolymers, thermoplastics or thermosetting polymers) or a blend thereof. In one or more embodiment the receptacle may be provided with a coloured exterior coating (for example fluoro yellow paint) for visibility. In one embodiment the receptacle is prepared by injection moulding or 3D printing.

[21] The invention will now be described in non-limiting examples with reference to the drawings. Like reference numerals are used throughout the drawings to depict like or similar elements of the receptacle.

[22] With reference to Figure 1, one example of a receptacle 1 for seating a spirit level 2 is shown. The receptacle 1 is in the form of a cone having a body 3 (in this case conical), an upper surface 4 and a base 5. The base has a flat portion 5a enabling the user to place it on a flat surface. An opening 6 is provided in the upper surface 4 for receiving the spirit level 2 and providing access to an internal space (not shown) for seating at least a portion of the spirit level 2. The body 3 is tapered from the upper surface 4 to the base 5.

[23] Figure 2 shows a top view of the receptacle 1. The upper surface 4 includes a relatively flat portion 8 suitably having a diameter of about 140mm and in which the opening 6 is suitably centred. -3- 09 01 25 In this example, the spirit level 2 has a rectangular cross section so in order to accommodate the spirit level 2 the opening 6 is also rectangular in shape. Suitably the opening has dimensions of 68mm length and 33mm width so as to accommodate a standard commercially available spirit level 2. The opening 6 provides access to an internal space 7 which in this example is also suitably rectangular in shape having similar dimensions to the opening and forming a channel 7a. Suitably the channel has a depth of about 225mm. Note that in this Figure, the channel is not located in the position as shown. The channel 7a is directed vertically from the opening towards the base 5. The body 3 from the edge of the substantially flat portion 8 of the upper surface 4 to the base 5 suitably has a length from top to bottom of about 275mm. The base 5 suitably has a diameter of about 280mm. Suitably the total weight of the receptacle 1 is about 7 kilograms so that it has weight to accommodate large spirit levels as well as small spirit levels in the upright (or a substantially upright) position (see Figure 1).

[24] Figure 3 shows a cross sectional view of the receptacle 1. Suitably the receptacle 1 includes a rebated handle 9 for ease of carrying / lifting. The handle may be 100mm wide, 30mm long and 30mm deep. The body 3 includes a solid base suitably having a depth of about 50mm.

[25] It will be appreciated that the measurements referred to above can be varied. In one or more embodiments the dimensions may vary within the range (although dimensions outside these ranges could also be used other than for dimensions of the opening): diameter of the relatively flat portion - 100mm to 225mm; dimensions of the opening - 50mm to 100mm length and 20 to 50mm width; channel depth range - 200 to 400mm; length from the edge of the substantially flat portion to the base - 250 to 500mm; diameter of the base - 200 to 500mm; total weight of the receptacle - 2kgs to 15kgs; handle rebate range - 70mm to 120mm wide, 15mm to 40mm depth and height; and solid base depth - 10 to 150mm.

[26] Figures 4A, 4B and 4C show another example of a receptacle 1 for seating a spirit level. In this example the receptacle 1 is in the form of a dome having a semi spherical body 3, an upper surface 4 and a base 5. The base has a flat portion 5a enabling the user to place it on a flat surface. In this example the receptacle has a diameter of 280mm, a radius of curvature of about 140mm and a height from top to base of about 131mm (prior to applying the opening 6 -see Figure 4C), A rectangularly shaped centred opening 6 is provided in the upper surface 4 for receiving the spirit level 2 and providing access to a rectangularly shaped internal space 7 in the form of a channel 7a (shown in ghosting in Figure 4c) having similar dimensions to the opening 6 for seating at least a portion of a spirit level. In this example there is about 10mm between the bottom of the channel 7a and the base 5. Suitably the opening has dimensions of 70mm length and 32mm width so as to -4- 09 01 25 accommodate a standard commercially available spirit level 2. The channel 7a is directed vertically from the opening towards the base 5. In this example the body 3 includes a rebated handle 9 for ease of carrying / lifting and includes a lip 10 defining a recessed portion 11 (shown in ghosting in Figure 4B). Suitably the rebated handle is located about 70mm from the base and has a width of about 80mm, a height of about 30mm but an increased depth of about 80mm forming an about 16mm recessed portion defined by lip 10. The dimensions of the receptacle can vary as set out above suitably by a margin (plus or minus) 30%.

[27] In one or more embodiments the invention has the advantage that it can temporarily house or store a spirit level at a worksite safely but is easily and quickly accessible and is readily portable so that it can be easily moved within the worksite and from site to site. In this regard it is possible to place the receptacle right next to a working area. Further in one or more embodiments by using a bottom heavy design it is possible to keep the spirit level upright or substantially upright when not in use. Another advantage is that it can be easily stored in a tool box when taken offsite and the spirit level is easily locatable.

[28] Whilst this invention has been described with respect to building and construction industry where it may be used for example by carpenters, plasterers, brick layers, landscapers, the receptacle can be used for seating a spirit level in other industries where spirit levels are used, for example, DIY, agriculture and machine spare parts manufacture.

[29] From the foregoing, it will be observed that numerous modifications and variations can be effected without departing from the true spirit and scope of the novel concept of the present invention. It is to be understood that no limitation with respect to the specific example illustrated herein is intended or should be inferred. The disclosure is intended to cover, by the appended claims, all such modifications as fall within the scope of the claims. 30] Throughout this specification and the claims that follow, unless the context requires otherwise the words "comprise", "comprises", "comprising" will be understood to mean the inclusion of the stated integer, step or group of integers or steps but not the exclusion of any of other integer, step or group of integers or steps.
