Patented Sept-.' 25, 1934 SCREWLES S METlglfi CONSTRUCTIONALv Max 'Schmid, Nuremberg, Germany Application December 10, 1931, Serial No. 580,157

v In Germany November 8, 1931 1 Claim. (Cl. 46-35) Metal constructional sets are known, the base constructional material of which consists of perforated sheet metal strips which are to be fitted together by means of screws and nuts. Constructional elements made of resilient parts, such as spirals and the like are also known, which are connected by hinged or rigid joints. Such constructional sets are diflicult for a small child to manipulate and also too expensive to produce.

These objections are overcome'by the invention in asimple manner in that the constructional elements are made as small hollow bodies of rectangular, square or other shape, provided with bores and open on one side. These bodies can be fitted'togetherusing bolts and'discs to form allv kinds of rigid and movable'imitations of constructions of great dimension produced in the technical industries, or they can be simply -.threaded together and built up to form architectural. structures. The dimensions of the indi- Fig. 3 shows the different constructional elements placed the ones in the others and accommodated in a match box and the cover for the box in position for sliding reception therein, and

' Figs. 4 and 5 are detail sectional views taken respectively on lines 4-4-and 5-5 of Figure 2.

gether and building up these sheet-metal bodies 80 rigid and movable architectural and also movable structures can be imitated. In the case of the latter structures pins 0 are inserted through the bores b and fixed by means of discs d of any as suitable material (Fig. 1). i

As shown in Fig. 3, the diflerent'bodies are made in such dimensions that they can be placed the ones in the others and accommodated in the cover I of a match-box. The largest .constructional element 0 serves in this instance as the drawer for the cover 1. By this construction the constructional elements can be.employed as a gift and advertisement and also for demonstration and instruction. 1

I claim:--- 9 y A screwless metal constructional set, comprising in combination a box having the dimension of a match box and consisting of a cover and a metal drawer; said drawer having holes in its other to form sets and having holes in all the remainingsides, aplurality of wooden pins of a diameter equal to that of the holes in said drawer and in said elements, and a plurality of discs each having a bore equal to the diameter of said pins adapted to be slipped on to said pins, to secure the same in position in the holes in said bodies and said drawer, said drawer adapted to accommodate said sets of box shaped bodies, said pins and said discs and to be closed by said cover.
