Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a do-it-yourself assembly construction piece, and more particularly to an assembly construction piece that can be selectively combined to build various objects.

2. Description of Related Art

Do-it-yourself (DIY) assemblies in accordance with the prior art usually have a specific configuration, and the pieces for a specific assembly cannot be used to build other objects. For example, a shelf assembly is composed of multiple long straight rods with multiple threaded holes and is assembled by screwing screws into the threaded holes to combine the rods together. Therefore, angles between two rods and configuration of the shelf assembly are constant and cannot be changed. When the shelf assembly is not used, the rods are virtually impossible to form other assemblies.

The present invention has arisen to mitigate or obviate the disadvantages of conventional DIY modules.

SUMMARY OF THE INVENTION

The main objective of the present invention is to provide do-it-yourself assembly construction pieces that can be selectively combined to form various objects.

Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.

Another one of the single plane multiple point connecting pieces has four connecting portions (72) formed respectively at four ends of the body (70b).

With reference to FIG. 8, an eighth embodiment of the do-it-yourself assembly construction piece is an adjustable connecting piece and has a straight body (80), one connecting portion (82) and an elongated hole (88). The straight body (80) has two ends. The connecting portion (82) is formed at one end of the body (80), and the elongated hole (88) is defined through the body (80) near the other end, is countersunk and has a bore diameter (not numbered). The bore diameter of the elongated hole (88) is the same as the through hole (822) in the connecting portion (82). A fastener slidably passes through the elongated hole (88) to connect the adjustable connecting piece to an adjacent connecting piece.

With reference to FIG. 9, a ninth embodiment of the do-it-yourself assembly construction piece is a pivoting connecting piece that has two bodies (90) and two connecting portions (92). Each body (90) has two ends (not numbered). Two of the ends are connected pivotally to each other. A connecting portion (92) is formed at the other end of each body (90).

With reference to FIGS. 10A and 10B, a tenth group of the do-it-yourself assembly construction pieces has multiple orthogonal corner pieces. Each orthogonal corner piece has an L-shaped body (100a, 100b) and at least three connecting portions (102). The L-shaped body (100a, 100b) has multiple ends (not numbered), and the connecting portions (102) are formed respectively on the ends of the L-shaped body (100a, 100b).

Another one of the orthogonal connecting pieces has four connecting portions (102) are formed respectively on and extending respectively from ends of the body (100b).

With reference to FIGS. 11A and 11B, an eleventh group of the do-it-yourself assembly construction pieces has multiple acute three-axis corner pieces with flat abutting faces. The acute three-axis corner pieces are similar respectively to the orthogonal corner pieces having an L-shaped body (110a, 110b) and multiple connecting portions (112) but further have a flat abutting face (114) formed at an included angle on the L-shaped body. One of the three-axis corner pieces has three connecting portions (112) formed respectively on and extending from corresponding ends of the body (110a). Another one of the three-axis corner pieces has four connecting portions (112) formed respectively on and extending from ends of the body (110b).

With reference to FIG. 12, a twelfth embodiment of the do-it-yourself assembly construction piece is an offset linear piece that has a long body (120) and two connecting portions (not numbered). The long body (120) has two ends (not numbered) that are bent in different directions and are parallel to each other.

With reference to FIG. 13, a thirteenth embodiment of the do-it-yourself assembly construction piece is a flat curved corner piece that has a curved body (not numbered) and two connecting portions (not numbered). The curved body is curved transversely and subtends an arc of 60°, 90°, 120° or any number of degrees evenly divisible into 360°.

When the assembly construction pieces are assembled, two connecting portions of adjacent assembly construction pieces overlap to align the through holes. Then, a fastener is passed through and secured in the through holes. Preferably, the fastener is composed of a flat-head rod and a sleeve nut. The concave face on the body of one assembly construction piece mates with the convex distal edge of an adjacent assembly construction piece to make the adjacent assembly construction pieces adjustable in angle and in position. Therefore, the assembled objects have more variety.

With reference to FIGS. 14 to 17, numerous objects can be constructed using multiple assembly construction pieces. Examples of objects constructed from the assembly construction pieces include a chair, a stool, a shelf frame and a bike-rack.

With reference to FIG. 18, any of the assembly construction pieces can be implemented with an anti-rotation device (180) comprising a toothed through hole (184), a flat-head bolt (187) and a sleeve nut (186). The toothed through hole (184) is formed by forming teeth on an inner surface of the through hole in the connecting portion (182). The sleeve nut (186) has a toothed outer surface (188) corresponding to and engaging the toothed through holes (184) on adjacent assembly construction pieces. The flat-head bolt (187) screws into the sleeve nut (186) to hold the sleeve nut (186) in the toothed through holes (184) and keep the adjacent assembly construction pieces from rotating.

The do-it-yourself assembly construction pieces as described can be used to make various objects limited only by a user's imagination. Furthermore, the assembly construction pieces can be detached and reused again to construct other objects.

Although the invention has been explained in relation to its preferred embodiment, many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
