Abstract

A modular platform system utilizing a number of components including a platform. The platform is configured so that each of the components may interchangeably connect to any side of the platform. The components include, for example, handrails and stairways, as well as other platforms. The platform and most of the components are formed from single, continuous pieces of metal.

Claims

1. A platform system comprising:

a horizontal platform structure configured to support a load imposed by a person standing or walking, said platform structure extending between a first end and a second end to define an axial direction;

a first support structure located at said first end of said horizontal platform structure such that said first end of said horizontal platform structure is elevated and supported by said first support structure;

a second support structure located at said second end of said horizontal platform structure such that said second end of said horizontal platform structure is elevated and supported by said second support structure;

said platform structure having at least two modular platforms each comprising a top surface and first, second, third, and fourth side surfaces that are planar, dimensionally consistent, and mutually interchangeable with each other, said side surfaces each comprising a respective side connection arrangement such that side connection arrangements of each of the first, second, third, and fourth side surfaces are functionally identical with each other;

a selected side surface of said first, second, third, and fourth side surfaces of a first modular platform of said at least two modular platforms being opposed to a selected side surface of said first, second, third, and fourth side surfaces of a second modular platform of said at least two modular platforms in an abutting relationship, said first and second modular platforms being interconnected using said respective side connection arrangement such that said selected side surface of said first modular platform and said selected side surface of said second modular platform engage one another to form a connecting structure and thereby support the load without a support structure under the connecting structure; and

said first modular platform and said second modular platform each having a respective one of first and second handrail structures removably connected to a respective side surface thereof via respective side connection arrangement that is adjacent to said selected side surface, such that the first and second handrail structures are situated in the axial direction of the horizontal platform structure but upright posts of the first and second handrail structures do not form part of the connecting structure between the first modular platform and the second modular platform.

2. The platform system of claim 1, wherein said side connection arrangements each comprise a plurality of apertures that align with corresponding apertures of another one of said side connection arrangements for receipt of elongate fasteners.

3. The platform system of claim 2, wherein said plurality of apertures of each side surface comprise a first pair of elongate slots and a second pair of elongate slots defined along said each side surface to allow insertion of said elongate fasteners at any position within the elongate slots.

4. The platform system of claim 3, wherein said elongate slots are substantially horizontal along said each side surface.

5. The platform system of claim 2, wherein said elongate fasteners are bolts each having a corresponding nut.

6. The platform system of claim 1, wherein said first support structure comprises a stairway having a bottom end and a top end, said top end being connected via said side connection arrangement of the respective side surface of said first modular platform that is opposite said selected side surface of said first modular platform.

7. The platform system of claim 6, wherein said second support structure comprises a vertical stand.

8. The platform system of claim 7, wherein said vertical stand has a rise substantially equal to that of said stairway.

9. The platform system of claim 1, wherein each said handrail structure comprises an inverted generally U-shaped outer rail, a horizontal midrail, and a horizontal toeboard.

10. The platform system of claim 9, wherein said generally U-shaped outer rail is constructed from a single, continuous piece of tubular metal.

11. The platform system of claim 1, wherein said platform structure has at least three modular platforms extending in the axial direction.

12. The platform system of claim 1, wherein said platform structure further has at least one modular platform connected to the respective side surface of one of said at least two modular platforms that is adjacent said selected side surface in a direction lateral to said axial direction.

13. The platform system of claim 1, comprising a stairway having a bottom end and a top end, said top end being connected via said respective side connection arrangement to the respective side surface of said first modular platform that is opposite said selected side surface of said first modular platform.
