ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention is in the field of building systems, and more particularly, pertains to a plurality of interconnecting members which secure in a rigid and stable manner without the use of fasteners, adhesives, or the like, which are easily assembled and disassembled without the need for tools. Building system members can be made in any number of sizes and scales allowing building systems to create life size playhouses, utility sheds, bins and various other toy and play scale structures. The building systems are designed to be safely and easily used by adults and children alike.
SUMMARY OF THE INVENTION
The general purpose of the present invention are building systems which do not require the use of fasteners, adhesives, or tools.
According to one embodiment of the present invention, there is provided a plurality of intermediate members, having upper and lower beveled portions, four notches, a tongue joint, a groove joint, larger inbound shoulders and smaller outbound shoulders. There are also provided upper and lower members which are constructed using the same principles as the intermediate portions with many like features.
One significant aspect and feature of the present invention are the various means of interlocking member ends in ways that create rigid and sturdy structures.
Another significant aspect and feature of the present invention are the various means of interlocking member edges for added stability.
A further significant aspect and feature of the present invention is smaller outbound shoulders than inbound shoulder which prevents damage during assembly and disassembly.
An additional significant aspect and feature of the present invention are the unlimited structure configurations using the building systems.
Still another significant aspect and feature of the present invention is the ability to use wood, plastic or metal in construction.
Yet another significant aspect and feature of the present invention are building systems which requires no tools for assembling. Components are reuseable to create other structures.
Having thus described embodiments of the present invention, it is the principal object of the present invention to provide a building system which requires no fasteners or adhesives for securation.
One object of the present invention is to provide a building system which is easy to assembly by adults and children.
Another object of the present invention is to provide a portable building system.
A further object of the present invention is to provide a building system which requires no tools for construction.
An additional object of the present invention is to provide building systems which are easy to breakdown, transport, and store. Compact storage for components that can build relatively large and stable structures.
Still another object of the present invention is to provide building systems which create useful structures such as, but not limited to retail displays, playhouses, shipping boxes, and camping cabins. User-friendly, intuitive, as easy as play for a child.
Other objects of the present invention and many of the attendant advantages of the present invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings, in which like reference numerals designate like parts throughout the figures thereof and wherein:
