Abstract

An assembly upon which a user stands includes a platform. The assembly includes a first work stand and a second work stand. Each work stand has a front frame and a rear frame. The assembly includes a first plank adapter engaged with the first work stand. The first plank adapter has an attachment portion and a bar. The assembly includes a second plank adapter engaged with the second work stand. The platform rests on and is supported by the first and second plank adapters. The present invention pertains to a work stand for holding a platform upon which a user stands. A plank adapter that is engaged with a front frame of a work stand to hold a platform. A method for a user to stand above ground. A method for forming a work stand.

First claim

1 . An assembly upon which a user stands comprising:
a platform having a first hook and a second hook extending from a first end of the platform, and a third hook and a fourth hook extending from a second end of the platform, the second end of the platform in opposition with and spaced relation with the first end of the platform, the platform defining a plane on which the user stands; a first work stand; a second work stand, each work stand having a front frame and a rear frame, each frame having a first rail and a second rail in parallel and spaced relationship with the first rail, a front cross bar engaged with the first and second rails of the front frame, a rear cross bar engaged with the first and second rails of the rear frame, a first spreader engaged with the first rail of the front frame and the first rail of the rear frame, a second spreader engaged with the second rail of the front frame and the second rail of the rear frame, the front frame and the rear frame of each work stand forming an upside down V, the front frame's top engaged with the rear frame's top; a first plank adapter engaged with the first work stand; the first plank adapter has an attachment portion and a bar, the attachment portion engaged with the bar and the first work stand to hold the bar in spaced relationship with the first work stand, the first and second hooks on the first end of the platform engage with and rest on the bar to hold the platform in place on the bar; and a second plank adapter engaged with the second work stand, the second plank adapter having a bar on which the third and fourth hooks on the second side of the platform engage with and rest to hold the platform in place on the bar of the second work stand.

2 . The assembly of claim 1 wherein the bar has a first end and a second end, the attachment portion has a first flange engaged with the bar in proximity to the first end of the bar and to the first rail of the front frame of the first work stand, and the attachment portion has a second flange engaged with the bar in proximity to the second end of the bar into the second rail of the front frame of the first workstation.

3 . The assembly of claim 2 wherein the first flange is engaged with the outside of the first rail of the front frame of the first work stand, and the second flange is engaged with the outside of the second rail of the front frame of the first work stand.

4 . The assembly of claim 3 including fasteners that attach each flange to each flange's corresponding rail.

5 . The assembly of claim 4 wherein the first flange is attached with the fasteners in proximity to the top of the first rail of the first work stand and the second flange is attached with the fasteners in proximity to the top of the second rail of the first work stand.

6 . The assembly of claim 5 wherein the bar has at least a portion of its outer perimeter being curved to conform to the first hook and the second hook of the platform that rests upon the bar.

7 . The assembly of claim 6 wherein the first flange and the second flange each have an opening in which the bar of the first plank adapter is fixed.

8 . The assembly of claim 7 wherein the first flange and the second flange each have a cut out in which the top of the first frame of the first work stand fits.

9 . The assembly of claim 8 wherein the first flange and the second flange each have a first section through which the fasteners extend into the first rail and the second rail, respective, and a second section that has the opening in which the bar of the first plank adapter is fixed, the first section having three sides, the second section having essentially a half oval perimeter.

10 . A work stand for holding a platform upon which a user stands, the platform having a first hook and a second hook extending from a first end of the platform, and a third hook and a fourth hook extending from a second end of the platform which are supported by a second work stand, the second end of the platform in opposition with and spaced relation with the first end of the platform, the platform defining a plane on which the user stands, the first work stand comprising;
a front frame and a rear frame, each frame having a first rail and a second rail in parallel and spaced relationship with the first rail, a front cross bar engaged with the first and second rails of the front frame, a rear cross bar engaged with the first and second rails of the rear frame, a first spreader engaged with the first rail of the front frame and the first rail of the rear frame, a second spreader engaged with the second rail of the front frame and the second rail of the rear frame, the front frame and the rear frame forming an upside down V, the front frame's top engaged with the rear frame's top; and a first plank adapter engaged with the front frame; the first plank adapter has an attachment portion and a bar, the attachment portion engaged with the bar and the front frame to hold the bar in spaced relationship with the first work stand, the first and second hooks on the first end of the platform engage with and rest on the bar to hold the platform in place on the bar.

11 . A plank adapter that is engaged with a front frame of a work stand to hold a platform, the platform having a first hook and a second hook, the adapter comprising:
an attachment portion; and a bar, the attachment portion engaged with the bar and the front frame to hold the bar in spaced relationship with the first work stand, the first and second hooks on the platform engage with and rest on the bar to hold the platform in place on the bar.

12 . A method for a user to stand above ground comprising the steps of:
unfolding a first work stand having a first plank adaptor and placing the first work stand at a desired first location; unfolding a second work stand having a second plank adaptor and placing the second work stand at a desired second location; placing a first hook and a second hook of a platform on the plank adaptor of the first work stand; and placing a third hook and a fourth hook of the platform on the plank adaptor of the work stand so the platform is supported by the first and second work stands above ground, the first plank adapter engaged with a front frame of the first work stand; the first plank adapter has an attachment portion and a bar, the attachment portion engaged with the bar and the front frame to hold the bar in spaced relationship with the first work stand,. the second plank adapter engaged with a front frame of the second work stand; the second plank adapter has an attachment portion and a bar, the attachment portion engaged with the bar of the second work stand and the front frame of the second work stand to hold the bar of the second work stand in spaced relationship with the second work stand.

13 . The assembly of claim 1 wherein the bar has a first end and a second end, the attachment portion has a first flange engaged with the bar in proximity to the first end of the bar and engages with the top of the first work stand, and the attachment portion has a second flange engaged with the bar in proximity to the second end of the bar and the top of the first work stand.

14 . The assembly of claim 13 wherein the first flange has a first arm that rests on the top of the front frame, a second arm that rests on the top of the rear frame, a base that extends through a gap between the front frame and the rear frame and below the top of the front and rear frames, the bar engaged with the first flange between the first arm and the second arm and above the base; and the second flange has a first arm that rests on the top of the front frame,
