Description
Background of the Invention
1. Field of the Invention
This invention relates to a block assembly and devices made from the block assembly, and more particularly to a block assembly providing plane blocks with coupling concave (recessed) portions and joint blocks with coupling convex (protruding) portions which are successively coupled to each other to assemble not only a planar body but also a three-dimensional solid body, and devices such as a chandelier or an ornament prepared from the block assembly.
2. Description of the Prior Art
There are many toys that include building blocks for making an unlimited number of items. Some of the toys merely provide toy bricks that are secured together to form various objects. Toys of the brick type cannot provide numerous shapes and devices, however, due to the limitations imposed by the building blocks and the fact that such building blocks can only be connected to one another in limited ways.
Erector sets offer more flexibility then do brick-based toys, but they are also subject to limitations because screws and nuts are required to join together the toy beams and girders that serve as the building blocks. Moreover, such toys have connections limited to only a few degrees of freedom; this restricts the variety of objects that can be made therefrom.
Still other toys, such as the well-known "LEGGO" (trademark) toy, are free of screws and nuts but offer limited degrees of freedom in constructing various articles or devices. Moreover, the "snap"-type connectors provided therewith provide a relatively weak interconnection.
Another common shortcoming of the known devices is that any article or device made therefrom is forever an assembled device, i.e., there are no suitable means for converting such article into a permanent device or work of art.
What is needed, then, is a construction toy having building blocks with unique coupling means to increase the number of degrees of freedom available to the user thereof. A need also exists for a means whereby completed articles made of up individual building blocks could be converted into a permanent one piece device.
However, in view of the prior art at the time the present invention was made, it was not obvious to those of ordinary skill in this art how such a device could be provided.
Summary of the Invention
The longstanding but heretofore unfulfilled need for a building block toy having increased degrees of freedom, improved interconnecting means, and means for preserving articles made thereby is now met by a system that provides two basic building blocks of unique configuration and structural qualities.
The first basic building block is called hereinafter a "plane" block and the second type of block is referred to hereinafter as a "joint" block. Joint blocks have protruding coupling means and plane blocks have recesses formed therein to receive said protruding coupling means.
More particularly, each plane block has formed therein at least one coupling recess in the form of a slot-like recess disposed along the center of at least one side thereof.
Each joint block includes at least one coupling protrusion projecting outwardly from at least one side thereof. A pincer-like pair of pinch members are formed in the tip of each coupling protrusion; said pinch members are adapted to frictionally grasp a coupling recess formed in a plane block.
The building blocks are preferably formed of a synthetic resin selected from the group of resins including acrylic resin, styrene resin, ABS resin, or other suitable resin. After an article has been constructed by assembling together the building blocks in a preselected pattern, the article is preserved by immersing it for a preselected time in a bath of methyl ethyl ketone, toluene, or other suitable solvent. The solvent "melts" the resin and seals the interstitial spaces between the structural parts of the article. The resulting one piece article is removed from the bath and used as desired.
It is therefore understood that an important object of this invention is to advance the art of building block-related toys.
Another object is to provide a means whereby the toys made of building blocks may be preserved as integral devices.
These and other important objects, features, and advantages of the invention will become apparent as this description proceeds.
The invention accordingly comprises the features of construction, combination of elements and arrangement of parts that will be exemplified in the construction hereinafter set forth, and the scope of the invention will be indicated in the claims.
