The disclosure relates to extension devices and more particularly pertains to a new extension device for measuring angles on a radiused corner. The device includes a base that is attachable to an anvil of a combination square to increase the width of the combination square. The device also includes a pair of plates that are attachable to the base, and which partially extend across the anvil, for attaching the base to the anvil.
The prior art relates to extension devices including a variety of combination squares for measuring various angles involved with construction. The prior art discloses a variety of extension devices that can insertably receive a framing square for retaining the framing square at a selected location on a member. In no instance does the prior art disclose a base that can slidably receive an anvil of a combination square and insertably receive a blade of the combination square.
An embodiment of the disclosure meets the needs presented above by generally comprising a base that has a blade slot extending therein to insertably receive a blade of a combination square. The base has a channel is integrated therein to receive an anvil of the combination square. The base has a width that is greater than the width of the anvil such that the base extends beyond a radius of a corner is measured with the combination square thereby enhancing accuracy of the combination square. A pair of plates is each of the plates is positionable on the base to retain the anvil of the combination square in the channel.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
The channel 20 is oriented to extend along a common axis with respect to the blade slot 14. The base 12 has a first end 40, a second end 42 and an outer surface 44 extending therebetween. The outer surface 44 has a top side 46 and a bottom side 48, and the base 12 is elongated between the first end 40 and the second end 42. The blade slot 14 extends from the first end 40 toward the second end 42, and the blade slot 14 is centrally positioned on the first end 40.
The channel 20 extends from the top side 46 toward the bottom side 48, and the channel 20 extends between the first end 40 and the second end 42. The channel 20 is centrally positioned between a first lateral edge 50 and a second lateral edge 52 of the base 12. The blade slot 14 is centrally positioned in the channel 20 and the channel 20 has a lower bounding surface 54. A bottom surface 56 of the anvil 22 of the combination square 18 rests on the lower bounding surface 54 such that the anvil 22 of the combination square 18 extends along a full length of the channel 20.
The blade slot 14 has a terminal end 58 and a leading edge 60 of the blade 16 of the combination square 18 is abutted against the terminal end 58. The top side 46 has a pair of first wells 62 each extending toward the bottom side 48, and the first wells 62 are spaced apart from each other and are distributed along the first lateral edge 50 of the base 12. The top side 46 has a pair of second wells 64 each extending toward the bottom side 48. The second wells 64 are spaced apart from each other and are distributed along the second lateral edge 52 of the base 12. Each of the first wells 62 and the second wells 64 has a bounding surface 66, and the bounding surface 66 is threaded.
A pair of plates 68 is provided and each of the plates 68 is positionable on the base 12. Each of the plates 68 extend partially over the channel 20 when the plates 68 are positioned on the base 12 to retain the anvil 22 of the combination square 18 in the channel 20. Each of the plates 68 has a lower surface 70 and an upper surface 72, and the lower surface 70 of each of the plates 68 rests against the top side 46 of the outer surface 44 of the base 12 when the plates 68 are positioned on the base 12. Each of the plates 68 covers a respective one of the pair of first wells 62 or the pair of second wells 64 when the plates 68 are positioned on the base 12.
A plurality of fasteners 74 is each extendable through a respective one of the plates 68 to engage the base 12 for attaching the plates 68 to the base 12. Each of the fasteners 74 has an outside surface 76 and the outside surface 76 of each of the fasteners 74 is threaded. Moreover, the outside surface 76 of each of the fasteners 74 threadably engages the bounding surface 66 of a respective one of the first wells 62 and the second wells 64. Each of the fasteners 74 may comprise a screw or other type of multiple use, mechanical fastener.
In use, the anvil 22 of the combination square 18 is positioned in the channel 20 and the blade 16 is positioned in the blade slot 14 such that the blade 16 abuts the terminal end 58 of the blade slot 14. Each of the plates 68 is positioned in the base 12 such that each of the plates 68 extends partially over the anvil 22. Each of the fasteners 74 is extended through the respective plate 68 to attach the respective plate 68 to the base 12. In this way the base 12 is attached to the combination square 18. As is most clearly shown in
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
