Abstract
A first structural member having a portion beveled at an angle of 45.degree. which includes a mortise in the form of a generally cylindrical groove is joined to a second structural member having a portion beveled at an angle of 45.degree. which includes a tenon in the form of a generally cylindrical rib, with the beveled portions in an abutting relationship by a joint formed by the rib being snugly fitted in the groove. The members may be joined at a straight angle or at a right angle, and may be employed for producing modular structural frames; articles of furniture; modular toy constructions; wall attachments; flooring boards and other arrangements wherein the flexibility of straight angle and right angle permutations of interlocking members of standardized elongated configurations are utilized.
Claims6
An article of manufacture, comprising:
- first and second members, said first member having a portion beveled at an angle of 45.degree., said second member having a portion beveled at an angle of 45.degree., said beveled portion of the first member including a recessed portion, said recessed portion including a cylindrical rib which extends outwardly beyond the plane of the beveled portion of the first member, said beveled portion of the second member including a projecting portion, said projecting portion including an open cylindrical groove which extends inwardly beyond the plane of the beveled portion of the second member, said first and second members being joined together at the beveled portions by a joint of said rib being fitted in said groove.
An article of manufacture, comprising:
- a member having first and second opposite ends having beveled portions at an angle of 45.degree., said beveled portion of the first end extending in a direction opposite to the beveled portion of the second end to form long and short sides on said member, said beveled portion of said first end including a recessed portion, said recessed portion including a cylindrical rib which extends outwardly beyond the plane of the beveled portion of the first end, said beveled portion of said second end including a projecting portion, said projecting portion including a cylindrical open groove which extends inwardly from the plane of the beveled portion of said second end, said cylindrical rib and cylindrical groove being sized whereby the cylindrical rib snugly fits within the cylindrical groove of another such member.
