Abstract

A toy building element which is adapted to be interengaged with a similar or identical building element comprising a hollow rectangular box which has an exterior top face with a plurality of rows of a plurality of equally spaced cylindrical projections which extend above the top face and which are provided with boxes having diameters which are the same as cylindrical pin elements which project in an opposite direction from an interior face within the box. The diameter of the pin elements is substantially equal to the spacing between adjacent cylindrical projections of adjacent rows. This makes it possible to interengage the cylindrical pin of one building element between the cylindrical projections of another building element or to engage the pins into the bores of the cylindrical projections.

TOY CONSTRUCTION SYSTEMS This invention concerns improvements in toy construction systems, through which important structural and practical advantages are gained.

Among the many toy construction systems known in the prior art, particular attention should be paid to those comprising hollow pieces open on one of their bases and provided, internally and externally, with protuberances intended to fit mutually to form toy constructions by coupling different types of pieces.

On the basis of this known principle, several variations and improvements have been made to achieve more satisfactory results, by providing new dimensional relations, different arrangements and positioning of protuberances, and changes in their number and shape.

The main purpose of this invention is to improve upon these features of construction systems by providing new types of pieces allowing for a wider range of .positional variations, thus increasing the number of toy constructions possible, which is not easy to accomplish with the systems known so far.

For a better understanding of the invention, drawings are attached showing practical applications, which are provided only by way of example. In the drawings:

FIG. 1 is a top view of one of the pieces made according to the invention.

FIG. 2 is a bottom view of the piece shown in FIG. 1.

FIG. 3 is a lengthwise section of the same piece, along line III-III of FIG. 1.

FIGS. 4 to 7 illustrate four cases of relative positions obtainable with two adjacent pieces (one of six and another of two external protuberances), as seen transversely.

FIGS. 8 to 11 illustrate a further four positional combination (using the same pieces), as seen in a lengthwise or end-to-end coupling.

FIGS. 12 and 13 are respectively a top view and a side view of a modification of the pieces of the toy construction system, that allows for a much greater variety in coupling.

FIGS. 14 and 15 illustrate partially new types of coupling, as seen transversely and lengthwise respectively.

As shown in the drawings, the improvements in toy construction systems provided by the invention are based upon the provision of basic pieces in the form of hollow boxes 1, open at their base, and having a top exterior face with a plurality of cylindrical projections or external protuberances 2, of a diameter D as well as internal protuberances 3, of a diameter D,, the ratio between these diameters being preferably 1:3, although there may be any other suitable ratio between said diameters.

It is an essential requirement that the external protuberances 2 have a central hole or cavity 4, of a diameter equal to that of the internal protuberances 3, so that concentric coupling may take place between both types of protuberances.

The external protuberances 2 are arranged in lengthwise rows f and transversal columns c, the figures attached being illustrative of a general case in which there are two rows f, and f and three columns 0,, c and The arrangement of the internal protuberances 3 is in the form of alternate rows, where distance L (FIG. 2) between any two protuberances, both considered lengthwise and transversely, equals'l 2 where l is the diagonal distance between said protuberances.

The number of internal protuberances is related to the number of external protuberances by the following formula:

where f and c are respectively rows and columns of external protuberances, their product f.c corresponding therefore to the total number of said protuberances.

It is also essential that the width of the internal cavity of the basic pieces 1, in order to facilitate coupling, is determined by the following formula:

where D and D, are respectively the diameters of external and internal protuberances.

In the specific case illustrated in the drawings, where the ratio between the diameters of protuberances is 1:3, general formula above becomes reduced to:

According to this formula, whenever f equals 1, as is the case with the simplest basic piece, m =D and thus in this particular case the width of the cavity in the piece coincides with the diameter of the external protuberances, this type of simple piece having no internal protuberance whatever.

In the same formula, whenever f 2, m 20,; D,, and therefore there is one single internal protuberance.

It should be mentioned that in order to reinforce the internal protuberances 3, these may be arranged between lengthwise partitions 5 and transversal partitions 5', running from wall to wall inside the basic element 1. However, it should also be mentioned that whenever such reinforcement is not required, the internal partitions may be done without.

Optionally, the toy construction system of the invention may also comprise pieces such as those illustrated in FIGS. 12 and 13, the characteristic feature of which is that radial cuttings or notches 6 are provided in the external protuberances 2, or alternatively there is a reduction in height of the lateral walls of piece 1, so that by combining these special pieces with standard or basic pieces 1, the arrangements illustrated in FIGS. 14 and 15 become obtainable, there being no obstacle against external protuberances coinciding with the lower edge of the side walls of the pieces coupled together.

Thus, coupling between pieces may take three basic forms, namely: external protuberances 2 between internal protuberances 3 (FIG. 11); external protuberances 2 between internal protuberances 3 and the side walls of the basic element 1 (FIGS. 4, 5 and 8); and direct concentric coupling of protuberances (FIGS. 6,7 9 and 10). Further, there is an optional additional type of coupling if external protuberances coincide with the the walls of the basic element (FIGS. 14 and 15).

It will be easily understood that the coupling possibilities illustrated in FIGS. 4 to 7, 8 to 11 and 14 to 15 may be greatly increased, as these basic positions repeat themselves indefinitely from left to right and from top to bottom.

Apart from the basic couplings described above, and owing to the particular structure of the pieces in the toy construction system of the invention, still a further type of coupling may be achieved by opposing pieces to each other by their hollow open bases, this being possible because the internal protuberances of every piece fit the inside walls of the opposing piece, permitting in this way that toy constructions grow in two opposite senses.
