The disclosure and prior art relates to vise bases and more particularly pertains to a new vise base for quickly installing a vise on any ferrous surface.
An embodiment of the disclosure meets the needs presented above by generally comprising a base having a top platform and a pair of side walls perpendicularly coupled to an underside of the top platform. The top platform has a pair of threaded mounting holes extending from a topside through the underside proximal a front edge and a rear edge. The mounting holes is configured to receive a pair of fasteners to fix a vise to the top platform. A magnet housing is coupled to the base and has a front side separated from a rear side, a top side separated from an open bottom side, and a right side separated from a left side forming an inner cavity. The left side and the right side are coupled to an inner face of the pair of side walls and extend from proximal the front edge to proximal the rear edge of the top platform. A magnet is coupled to the magnet housing and comprises a pair of ferrous blocks, a non-ferrous median, and a magnetic core. The pair of ferrous blocks is coupled to the left side and the right side and extends from the front side to the rear side and from the top side to the open bottom side within the inner cavity. The non-ferrous median is coupled to the pair of ferrous blocks and extends from the front side to the rear side and from the top side to proximal the open bottom side within the inner cavity between the pair of ferrous blocks. The magnet has a core aperture extending from the front side to the rear side fully through the non-ferrous median and partially into each of the pair of ferrous blocks. The magnetic core is coupled within the core aperture and extends from the front side to the rear side. The magnetic core has a positive hemisphere and a negative hemisphere and is rotatable such that a north pole of the positive hemisphere and a south pole of the negative hemisphere can be horizontally oriented within the pair of ferrous blocks in an engaged position or alternatively vertically oriented within the non-ferrous median in an alternate disengaged position. The magnetic core thus magnetizes the pair of ferrous blocks in the engaged position and alternatively demagnetizes the pair of ferrous blocks in the alternate disengaged position. A magnet rod is coupled to the magnetic core and extends through a rod aperture of the front side of the magnet housing. A handle is coupled to the magnet rod and is used to rotate the magnet rod and thus the magnetic core from the engaged position to the alternate disengaged position.
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
A magnet housing 36 is coupled to the base 12 and has a front side 38 separated from a rear side 40, a top side 42 separated from an open bottom side 44, and a right side 46 separated from a left side 48 forming an inner cavity 50. The left side 48 and the right side 46 are coupled to an inner face 52 of the pair of side walls and extend from proximal the front edge 28 to proximal the rear edge 30 of the top platform. Each of the left side 48 and the right side 46 have an outer bridge portion 53 coupled to the pair of side walls 16. The outer bridge portion 53 has a height less than an overall height of the right side 46 and the left side 48. The outer bridge portions 53 form a pair of wall channels 54 along a bottom edge of the pair of side walls 16. The top side 42 is pitched and has a flat central section 56 and a pair of angled side sections 58. The flat central section 55 is parallel to, and spaced from, the underside 18 of the top platform and is configured to give clearance for the pair of fasteners 32. The front side 38 and the rear side 40 are thus hexagonal.
A magnet 60 is coupled to the magnet housing 36 and comprises a pair of ferrous blocks 62, a non-ferrous median 64, and a magnetic core 66. The pair of ferrous blocks 62 is coupled to the left side 48 and the right side 46 and extends from the front side 38 to the rear side 40 and from the top side 42 to the open bottom side 44 within the inner cavity 50. The non-ferrous median 64 extends from the front side 38 to the rear side 40 and from the top side 42 to proximal the open bottom side 44 within the inner cavity 50 between the pair of ferrous blocks 62. A width of the non-ferrous median 64 is less than 30% of a width of the inner cavity 50 between the left side 48 and the right side 46. The magnet 60 has a lower channel 68 defined along a bottom face 70 of the non-ferrous median 64 between the pair of ferrous blocks 62. The lower channel 68 may accommodate a break in a surface. The magnet 60 has a core aperture 72 extending from the front side 38 to the rear side 40 fully through the non-ferrous median 64 and partially into each of the pair of ferrous blocks 62. A profile of the core aperture 72 has two arcs passing through the non-ferrous median 64 each between 50° and 70° and two arcs passing through the pair of ferrous blocks 62 each between 110° and 130°. The magnetic core 66 is rotatably coupled within the core aperture 72 and extends from the front side 38 to the rear side 40. The magnetic core 66 has a positive hemisphere 74 and a negative hemisphere 76 and is rotatable such that a north pole 78 of the positive hemisphere 74 and a south pole 80 of the negative hemisphere 76 can be horizontally oriented within the pair of ferrous blocks 62 in an engaged position (as shown in
A magnet rod 84 is coupled to the magnetic core 66 and extends through a rod aperture 86 of the front side of the magnet housing. A handle 88 is coupled to the magnet rod 84 and is used to rotate the magnet rod 84 and thus the magnetic core 66 from the engaged position to the alternate disengaged position. The handle 88 has a cylindrical hub 90 coupled around the magnet rod 84 and a handle arm 92 perpendicularly extending from the hub 90. The handle 88 has a grip 94 coupled to the handle arm 92 proximal a distal end 96 thereof. A pair of stop rods 98 is perpendicularly coupled to the front side 38 of the magnet housing to limit the range of motion of the handle arm 92. The pair of stop rods 98 may be separated by 90° relative a central axis of the magnet core 66 and the magnet rod 84 to stop the handle 88 when the magnet core 66 is in the engaged and disengaged positions. The pair of stop rods 98 have a length less than a length of the hub 90.
In use, apparatus 10 is placed on a ferrous surface 82 and the handle 88 is rotated to move the magnet core 66 to the engaged position. The vise 34 is then fixed to the top platform 14 with the fasteners 32 and the pair of mounting holes 24. When desired, the handle 88 is rotated to move the magnet core 66 back to the disengaged position to reposition the apparatus 10 and the vise 34.
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.
