Nov. 25, 1958 G. r-1\v.\RETrcJ STRUCTURAL TOY AND MODEL BUILDING SET Filed Aug. 12, 1952 FIG. 4.

United States Patent O STRUCTURAL TOY AND MODEL BUILDING SET GianniFavaretto, Bergamo, Italy Application August 12, 1952, Serial No. 303,849

Claims priority, application Italy August 14, 1951 9 claims. (c1. t6-16.)

This invention relates to devices comprising a set of structural elements adapted to be connected together 4by means of projections on and sockets in said elements, in order to build toys and models. 4

A chief object of this invention is to provide elements of very light weight, capable of rm reciprocal connection by engagement over the widest possible surface with respect to the cross section of the elements.

According to this invention a set of structural elements for building toys and models, comprises prismatic hollow blocks provided with at least one projection on one side, adapted to penetrate into the bore in the adjacent element, said projection being hollow and of square section.

The invention shall be described with reference to the accompanying drawing, wherein:

Figure l is a perspective view of a single element;

Figures 2 and 3 are a longitudinal section and perspective view, respectively, of a double element;

Figure 4 is a perspective view of a triple corner element;

Figure 5 is a perspective view of a double auxiliary element;

Figure 6 shows a modification of Figure 3;

Figure 7 shows a modification of Figure 1;

Figure 8 shows a modification of Figure 7 with a lateral extension;

Figure 9 is a perspective view of a simple auxiliary element having two lateral extensions;

Figure 10 is a perspective view of an element according to Figure l, having two lateral extensions;

Figure 1l shows a modification of Figure 9;

Figure 12 is a perspective view of an element according to Figure 3, provided with two lateral extensions;

Figure 13 is a perspective view showing a corner structure built by means of elements according to Figure 3;

Figure 14 is a perspective view of a corner structure built by means of modifications of the elements shown in Figures l, 3 and 4;

Figures 15 and 16 are plan views showing two courses of elements for building a T-structure;

Figure 17 is a sectional view showing a structure composed of the previously illustrated elements;

Figure 18 is a vertical section showing a box and cover;

Figure 19 is a part sectional view of a panel.

The fundamental structural element shown in Figure l consists of a block B of prismatic shape, formed with an inner bore of square section, open towards the outside at two opposed block faces. At one of the open faces the block B is formed with a hollow extension A of square section, smaller in height than the block B and of a cross sectional area such as to permit a tight iit into the bore inthe block B of an adjacent element of the set.

The double element shown in Figures 2 and 3 comprises a block B formed with two -bores with parallel axes and two corresponding hollow projections A.

The triple corner element shown in Figure 4 comprises a block B' formed with three bores having parallel axes and three corresponding hollow projections A' of square section.

"ice

The auxiliary element shown in Figure 5 is similar to the element shown in Figure 3, but is deprived of projec-v tions A. lts bottom can be closed, if desired.

The elements shown in Figures 6 and 7 are similar to those shown in Figures l and 3, but are formed with a wall C greater in thickness which permits of building panels provided with protruding portions.

The elements shown in Figures 8 to l2 serve for connecting in the various directions further similar contiguous elements and are formed for this purpose with projections D of U-section, extending perpendicular to the common axis of the bores in the block B and projection A.

Figure 13 clearly shows the manner of building by means of elements of the type shown in Figure 3 only, walls, for instance of building models, with staggered joints between the elements. Figure 14 shows the manner of forming re-entering portions in the walls by utilizing elements formed with walls C of greater thickness.

Figures l5 and 16 show the manner of connecting the elements in the second course with staggered joints by utilizing elements of the type referred to by 4 in Figure 16.

In Figure 17, 5 denotes the element shown in Figure 5. It will be obvious that, since its projections A are shorter than the height of the element B, two projections A can be iitted from opposite sides into one and the same element 5.

The box shown in Figure 18 comprises a base panel obtained from elements as shown in Figures 1 and 5, lower edges obtained from elements 12 as shown in Figure 12, side walls obtained from elements according to Figure 1 and an inner bead on said side walls obtained by fitting elements 6 according to Figure 6. The cover abutting said bead is formed from elements according to Figure l, elements 3 according to Figure 3 and an element 5 which is utilized as a handle for the cover.

In Figure 19, D denotes a wire or band -serving for additionally connecting together the elements as shown in Figure 2 to form a panel.

From the preceding description it will be understood that, the bore in the block B being wide enough to leave only a lateral block wall of small thickness, the block is extremely light in weight-with respect to blocks proposed heretofore. Moreover, the square cross sectional shape of the hollow projections A prevents reciprocal rotation of the interlocked elements.

The above described elements are conveniently made by injection moulding from plastic material and can be of any desired color, transparent or translucid.

They can be employed for building a large variety of structures for use either as toys, architectural models or the like.

What I claim is:
