Folding stand for a portable crimping device
A folding stand adapted to be secured to the bottom wall of a portable crimping device which, in a folded position, is substantially flat against a wall portion thereof and, in an unfolded position, vertically raises the crimping device to a predetermined working height, the folding stand including a base portion, having a rear pivot axis, a mounting portion, having a front pivot axis, and a pair of elongated cross members for interconnecting the base and mounting portions, via oppositely directed fastening members, with opposed ends of the cross members being adapted to pivot, relative to the adjoining base and mounting members, between respective first and second stop point folding surfaces, in a folded position, and first and second stop point standing surfaces, in an unfolded position, the respective stop point folding and stop point standing surfaces being angularly spaced therebetween via first and second predetermined reflex angles.
1. A foldable stand for a portable crimping device, said foldable stand being adapted to be secured to a horizontal bottom wall surface of said crimping device, said foldable stand comprising in combination:
a. a base portion, including a pair of spaced, main chassis, longitudinal base members, interconnected, on first ends thereof, via a first transversely directed connecting portion and interconnected, inboard of second ends thereof, via a second transversely directed connecting portion, said base member second ends each having a horizontal coaxial first pivot aperture in a common first pivot axis, said second connecting portion including a pair of laterally separated, coplanar, first stop point folding areas and a circumferentially spaced pair of laterally separated, coplanar, first stop standing point areas;
b. a mounting portion, including a generally ring shaped body portion having a top surface, a bottom surface, a central aperture, a plurality of spaced through bores and a pair of aligned, spaced, attachment bosses, at opposite sides of a front end portion of said body portion, said attachment bosses each including a lateral, vertical attachment portion c. having an opposed, horizontal coaxial second pivot aperture in a common second pivot axis, parallel with said first pivot axis, each attachment boss including a second stop point folding area, in first common plane, and a circumferentially spaced second stop point standing area, in a second common plane;
c. a pair of elongated cross members, each having a top surface, a bottom surface and first and second ends having first and second through bores, respectively;
d. a first pair of oppositely directed fastening members for pivotally connecting said first ends of said cross members, via said first bores, with respective ones, of said base portion second ends, via said first pivot apertures, thereby permitting relative movement, between said base portion and said cross members, for a first predetermined reflex angle between said first stop point folding areas and said first stop point standing areas; and
e. a second pair of oppositely directed fastening members for pivotally connecting said second ends of said cross members, via said second bores, with respective ones, of said mounting portion attachment bosses, via said second pivot apertures, thereby permitting relative movement between said mounting portion and said cross members, for a second predetermined reflex angle between said second stop point folding areas and said second stop point standing areas.
2. The foldable stand of claim 1 , wherein said first predetermined reflex angle has an angular extent of about 315 degrees.
3. The foldable stand of claim 1 , wherein said second predetermined reflex angle has an angular extent of about 240 degrees.
4. The foldable stand of claim 1 , wherein, when said cross members abut said first and second stop point standing areas, respectively, said foldable stand is in an unfolded position.
5. The foldable stand of claim 4 , wherein said folding stand, in its unfolded position, utilizes the mass of said portable crimping device, acting via its center of gravity, through said first and second stop point standing areas, to retain said foldable stand in the unfolded position.
6. The foldable stand of claim 1 , wherein, when said cross members abut said first and second stop point folding areas, respectively, said foldable stand is in a folded position.
7. The foldable stand of claim 6 , wherein one of said mounting portion attachment bosses includes, in an outer end surface thereof, a further bore portion and said base portion first connecting portion includes a further through bore, said further bore and through bore being axially aligned when said foldable stand is in said folded position, with an additional fastening member, extending, through said further through bore into said further bore, being adapted to fixedly retain said base portion to said mounting portion, in said folded position, thus fixedly securing said folding stand, in its folded position, to said portable crimping device and being portable therewith.
8. The foldable stand of claim 7 , wherein, in said folded position of said folding stand, said folded stand adjoins a front surface portion of said portable crimping device.
9. The foldable stand of claim 7 , wherein said attachment boss further bore portion serves as retainer for said additional fastening member when said folding stand is in its unfolded position.
10. The foldable stand of claim 1 , wherein said bottom wall surface of said portable crimping device abuts the top surface of said mounting portion and is secured thereto, via a plurality of further fastening members, extending through said plurality of through bores, in the body portion of said mounting portion, into a plurality of aligned bores in said crimping device bottom wall surface.
11. The foldable stand of claim 1 , wherein said first and second pairs of fastening members take the form of stainless steel shoulder bolts.
12. The foldable stand of claim 1 , wherein said first transversely directed connecting portion includes an arced center portion that can serve as an operator handle during folding and unfolding of said foldable stand.
13. The foldable stand of claim 1 further including a parallel, auxiliary chassis, longitudinal base member, interconnected, on opposed ends thereof, via further transversely directed connecting portions, with one of said main chassis, longitudinal base members, inboard of the ends thereof.
14. The foldable stand of claim 13 , wherein the further connecting portions of said auxiliary chassis base member include a plurality of spaced through bores, said through bores being aligned with matching through bores in the base portion of a hydraulic pump normally mounted on a side surface of said portable crimping device, thereby permitting the mounting of said pump, via suitable fastening members, to said base portion.
15. The foldable stand of claim 13 , wherein the ends of bottom surfaces of said main and auxiliary chassis longitudinal base members are provided with respective foot portions, with the lowermost surface of each of said foot portions defining an area in a common plane, that, in turn, defines the footprint of said base portion.
