When the first and second leg assemblies are essentially perpendicular to the platform 12, the apparatus 10 is in a use state and the user is able to stand on the platform 12 and be supported by the first and second leg assemblies, as shown in FIG. 1. When the apparatus 10 is in the use state, the user is able to pick up the apparatus 10 by the handle 2 with only one of the hands without tipping the apparatus 10.

[0029] The present invention pertains to a method for a user with hands to stand on an apparatus 10. The method comprises the steps of placing the apparatus 10 that is in a use state in a desired location. The apparatus 10 comprises a platform 12 having a first end 14 and a second end 16 and a handle 2; a first leg assembly 20 rotatably attached to the platform 12 in proximity to the first end 14, a second kg assembly 22 attentively attached to the platform 12 in proximity to the second end 16, when the first and second leg assemblies are essentially in parallel with the platform 12, the apparatus 10 is in a folded state, when the first and on leg assemblies are essentially perpendicular to the platform 12, the apparatus 10 is in a use state and the user is able to stand on the platform 12 and be supported by the first and second leg assemblies, when the apparatus 10 is in the use state, the user is able to pick up the apparatus 10 by the handle 2 with only one of the hands without tipping the apparatus 10. There is the step of placing an object 57 on the platform 12. There is the step of grabbing the handle 2 in the platform 12 while the apparatus 10 is in the use state. There is the step of lifting the apparatus 10 by the handle 2 with one hand by the user while the user's other hand is free so the apparatus 10 does not tip and the object does not come off the platform 12. There is the step of placing the apparatus 10 back down on to ground with the object still on the platform 12.

[0030] Each handle 2 insert has a first flange 60 and a second flange 62 that forms an angle, preferably about 90, as shown in FIGS. 7 and 8, with the first flange 60. Essentially, the first flange 60 and second flange 62 together form an L shape. The second flange 62 has holes 5 that align with holes 5 in a support bar 6, as shown in FIGS. 4 and 5. The support bar 6 extends along, the centerline 30 of the platform 12 and is attached to the bottom 38 of the platform 12. Each end of the support bar 6 rests on a lip;4 of an end flange 66 at each end of the platform 12. By resting on a lip 64 of an end flange 66 at each end of the platform 12, the support bar 6 is supported by the leg assemblies which extend down from the end flanges 66. The support bar 6 provides support and strength to the platform 12. In addition, there are pluralities of crossbars 68 that extend across the width of the platform 12 and are attached to the bottom 38 of the platform 12 and to the support bar 6, through which they extend. The end of each crossbar is on the lip 64 of a side flange 70 of the platform 12 on each long side of the platform 12. The crossbars 68 add even further strength and support to the platform 12.

[0031] The first flange 60 has a first section 72 that extends from the second flange 62 and a second section 74 that has an oval shaped opening, as shown in FIGS. 7 and 8 that fits into and corresponds with the oval shaped opening in the platform 12 of the slot. The oval shaped opening in the second section 74 has a ridge 76 extending from the surface of the second section 74, along the perimeter of the oval shaped opening. A hinge 78 at each corner of the platform 12 attaches the leg assemblies to the platform 12.

[0032] FIG. 1 shows a perspective view of a work platform 12 with the legs 52, 54 extended and ready for use. The legs 52, 54 are designed to fold up under the platform 12 to allow for convenient storage of the work platform 12 when not in use. One possible form of handle 2 is shown.

[0033] FIG. 2 shows a top view of the work platform 12, with dimensions regarding the slot positions relative to each other and the platform. The handle 2 is formed by having slots 24, 26 in the work platform decking 57. The slots are located in the center of the work platform 12 above its center of gravity. These slots are sized to conform to the dimensions of a user's fingers. The slots are symmetric so as to be for use with either hand.

[0034] FIG. 3 shows a close up view of the handle 2 construction details. Handle inserts 44, 46 are located in the slots. These inserts ensure that any potentially rough edges remaining after slots are formed in the work platform 12 decking are covered up. These inserts also provide a deeper gripping surface for the comfort of the user. The inserts could be made of molded plastic.

[0035] FIG. 4 shows the underside of the work platform 12 and details of how the inserts 44, 46 might be attached. Holes 5 in the inserts and the central support hat 6 allow for the use of screws or pop rivets, etc.

[0036] FIGS. 9-1 1 are overhead, side and underneath views, respectively, of a handle insert with dimensions of a preferred embodiment. The dimensions of the insert may me changed depending on the loads and size of the apparatus 10.

[0037] For use, the apparatus 10 is carried by the user to a desired location, where the user unfolds each leg assembly until each leg assembly extends essentially perpendicularly from the platform 12, and is now in the use state. The operation of the binges and the leg assemblies is well known with work platforms.

[0038] The user will then stand on the work platform 12 in conduct whatever actions are necessary. When the user desires to move the work platform 12 to another location, but does not want to have to fold the work platform 12 up to the folded state, and wants to have use of a hand to be free to hold an object while the user lifts and moves the work platform 12 in the use state, the user with one hand inserts a sum in the first slot 24 and the four fingers in the second slot 26 and grabs the portion of the platform 12 that is disposed between the first slot 24 and the second slot 26. This effectively acts as a handle 2 for the user to then lift the work platform 12 while it is in a use state, and move the work platform 12 to another location without the work platform 12 tipping. The work platform 12 would not tip since the handle 2 is in the center of the platform 12, and by lifting up the platform 12 basically straight up, with the weight of the platform 12 evenly distributed around the handle 2, there is no unbalanced side that would otherwise cause the platform 12 to tip as it is left and. This way, objects on the work platform 12, such as paint cans, or hands with putty or oils, can stay in place on the work platform 12 while it is being moved, without having to be removed from the platform 12 are closed up.

[0039] It can be seen that the disclosed handle 2 satisfies the need for a means by which a user can grasp, lift, and move a work platform 12 with one hand while maintaining the work platform 12 in an upright position.

[0040] The handle 2 described is only one of many possible ways to accomplish the goals of this invention. Various other possible means could include having straps or handles similar to those used on brief eases or suit cases which are attached to the deck of the work platform 12. These handles could be made to stow flush with the upper surface of the work platform 12 when not needed. The apparatus provides means for a user to pick up a work platform with one hand while allowing the work platform to remain in a generally level orientation.

[0041] The apparatus 10 may be a Werner AP-30 work platform, modified to include a handle 2, which has a duty rating or 1 and able to support at least 250 pounds of load. The apparatus 10 can support greater loads, such as at least 500 pounds if so desired, with the platform and leg assemblies made thicker in material to support the increased load.

[0042] In an alternative view, as shown in FIGS. 12-15, the handle 2 alternatively is a strap 89 that is attached to the platform 12 at its middle 28 in a longitudinal relationship with the centerline 33 and at the balance point 91 of the apparatus 10. The strap 89 has an elongate portion 93 in spaced relationship with the platform 12 which a user grabs to lift the apparatus 10, and opposing connection portions 95 which extend down from the elongate portion 93 of the strap 89 and wrap around the center decking 97 of the platform 12 to attach the strap 89 to the platform 12. The opposing connection portions 95 split and form a loop around the center decking 97 to attach the strap 89 to the platform 12. By being positioned at the bellows 91 along the centerline 33, when the apparatus 10 is lifted by the strap 89, the platform 12 should not tip, but remain level. The strap 89 is between 0.5 inches thick and 3 inches thick and can be made out of cloth, plastic or metal. The elongate portion 93 can have chamfered or rounded edges so it is comfortable for the user to grab and limits any rubbing, cutting or pressure points to the user's hand.

[0043] Although the invention has been described in detail in the foregoing embodiments for the purpose of illustration, it is to be understood that such detail is solely for that purpose and that variations can be made therein by those skilled in the art without departing from the spirit and scope of the invention except as it may be described by the following claims.
