With reference now to the drawings, and in particular to FIGS. 1 to 9 thereof, a new and improved saw table apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
FIG. 1 illustrates a prior art support table 1, wherein a first and second rectangular framework 2 and 3 respectively is pivotally mounted underlying a central support 5, with a wing member 4 pivotally mounted to the central support to support an extended work support surface. FIG. 2 illustrates a saw table 6, wherein a framework 7 is spaced from the table 6 by a gap 8, wherein the framework 7 is pivotal from a vertical to a horizontal orientation for support of elongate workpieces thereon.
More specifically, the saw table apparatus 10 of the instant invention essentially comprises a rigid table plate member 11, with spaced parallel ends, with a first wing plate 12 and a second wing plate 13 pivotally mounted to the opposed ends of the plate member 11 by a respective first and second elongate hinge 14 and 15. When the first and second wing plates 12 and 13 are in a horizontal position, as opposed to the vertical orientation as illustrated in FIG. 3, the wing plates define an aligned planar support surface in a manner as illustrated in FIG. 9 for example. A first, second, third, and fourth elongate leg member 16, 17, 18, and 19 respectively are directed downwardly from a bottom surface of the plate member 11 defining a trapezoidal parrallelepiped. The lower terminal ends of the leg members 16-19 include respective cylindrical feet defining a first, second, third, and fourth cylindrical foot 16a, 17a, 18a, and 19a of the respective leg members 16-19, wherein the cylindrical feet define a common support plane parallel to the top surface of the plate member 11. A first side rung 20 is directed between the first and third leg member, with a second side rung 21 fixedly mounted to and directed between the second and third leg members. A first end rung 22 is mounted between the first and second leg members and a second end rung 23 is fixedly mounted between the third and fourth leg members, wherein the rungs 20-23 define a single plan parallel to the top surface of the plate member 11 to effect stability, as well as defining a bearing surface for associated tube junction sleeves 24a and 25a respectively mounted to the respective first and second end rungs 22 and 23. The first tube junction sleeve 24a mounts a first tube 24 oriented orthogonally to the first end rung 22, while the second tube junction sleeve 25a mounts a second tube 25 orthogonally relative to the second end rung 23. The first and second tubes 24 and 25 telescopingly receive a respective first and second wing leg member slidably and frictionally therewithin, while a respective first and second fastener 26a and 27a directed through the first and second tubes 24 and 25 may be optionally employed to maintain the respective first and second wing leg members 26 and 27 in a desired orientation relative to the respective first and second tubes.
The first and second wing plates 12 and 13 respectively mount first and second wings rigidly to exterior side surfaces of the wing plates. The wings define a planar top surface, wherein the planar top surfaces are aligned relative to one another of the spaced wings, and are spaced above and parallel to the top surface of the plate member 11. The first wing mounted to the first wing plate 12 includes a first and second respective horizontal tube 28 and 29 fixedly mounted to and extending orthogonally from an exterior surface of the first wing plate 12 directed rearwardly thereof. A rotatable locking collet 36 is mounted at each rear terminal end of the first and second horizontal tubes 28 and 29 formed of an equal lineal length. The first and second horizontal tubes 28 and 29 slidably receive the legs of a first "U" shaped extension member 38 therewithin to provide effective lengthening or shortening of the wing defined by the first and second horizontal tubes and the first extension member 38 wherein, as illustrated, the first and second horizontal tubes 28 and 29 are arranged parallel to one another. A first brace 30 is mounted orthogonally between the first and second horizontal tubes 28 and 29 rotatably mounting a first leg member junction sleeve 32 formed to an upper terminal end of the first wing leg member 26 to permit relative rotation of the first leg member junction sleeve 32 during collapse of the first wing member and reception of the first wing leg member 26 within the first tube 24. Similarly, spaced parallel third and fourth horizontal tubes 33 and 34 of equal length are orthogonally fixedly mounted to a rear terminal face of the second wing plate 13, with the rotatable locking collets 36 mounted to rearward and free terminal ends of the third and fourth horizontal tubes, wherein the tubes through the collets receive the legs of the second "U" shaped extension member 37 therewithin to permit extension of the support surface of the second wing, as defined by the third and fourth horizontal tubes 33 and 34 and the second "U" shaped extension member 37. A second brace 35 rotatably mounts a second leg member junction sleeve 31 that in turn is fixedly mounted to an upper terminal end of the second wing leg member 27, for use in a manner as described relative to the first wing member.
Reference to FIGS. 6 and 6a illustrates that the elongate leg members 16-19 each include an upper terminal end formed with a fastener 41 that is directed through an adjusting plate 39 mounted orthogonally to each end of the plate member 11 to permit vertical adjustment of the leg members 16-19 individually through an elongate slot 40 oriented vertically relative to the top surface of the plate member 11 to permit vertical height adjustment of the leg members relative to the plate member 11.
FIG. 7 illustrates the use of a power miter saw head 42 mounted to a support base 47 that is received on the top surface of the plate member 11. Accordingly, a workpiece directed about a top surface of the side wing members, as illustrated in FIG. 7, permits the workpiece "W" to be directed past the power miter saw 42 and the associated blade 43. Understandably, the base 45, as illustrated, is of a height substantailly equal to the defined height of each of the wing plates 12 and 13.
FIG. 8 illustrates the use of a "U" shaped yoke 44, with a bottom leg of the yoke fixedly mounted to a bottom surface of the plate member 11, with an upper leg of the yoke arranged to and overlying the top surface of the plate member 11, wherein the top leg of the yoke slidably mounts a radial arm saw head member 43a operative through an associated power motor 42a for use of the organization as a radial arm saw device.
FIG. 9 illustrates the side wing members arranged in a second or vertical orientation relative to the table plate member 11 defining a single support surface, wherein the top surface of the plate member 11 is coextensive with the interior faces of the first and second wing plates 12 and 13.
