In Fig. 1 there is illustrated an assemblage of toy construction elements which simulates a wheeled vehicle provided With hoisting mechanism. The assemblageis typical of a number of arrangements which it is possible to construct with a plurality of the basic elements and sub- The number of assemblies and the types of construche. S n

In Figs. 2 and 3 of the drawings, there is illustrated a strip member ID which constitutes one of the basic elements of the invention. The member consists of a relatively fiat narrow strip portion H provided with spaced apertures l2 and end formations E3. The strip portion ll may be made solid, or provided with recesses. effecting a saving of material, or with reinforcing ribs, providing increased strength. The end formations 13 include a tubular portion l4 projecting upwardly from the top face of the strip portion H. The tubular portion 14 is provided with a socket forming bore [1 which is preferably the same diameter as the apertures 12' in the strip portion ii. Projecting from the opposite face of the strip portion II is a relatively short pin l8 which is of a cross-sectional. diameter which permits it to be loosely positioned in the socket H or in an aperture 12. The pin l8 and the socket H are adapted to cooperate to permit a plurality of the strip members Hi to be positioned. in connected relation with the. members either superimposed on each other or extended at any desired angle relative to each other. Each end formation [3 is: also. provided with relatively short laterally extending pin members. [9- which are duplicates of each other but extend in opposite directions edgewise of the strip member iii in substantially the. sameplane as the. strip portion ll. Each pin member t9 is. slotted on the. end at 2E2. and. provided with a circumferential shoulder 21 near the free end thereof. The pin members iii. are of a crosssecti'onal diameter slightly lessthan the diameter of the apertures l2 in the strip portion ll and the shoulder M is of slightly greater diameter. The end of the pins IS may be-resiliently compressed by means of the slot to permit the shoulder 2| to pass through an aperture l2.

In Figs. 4 and 5 a wheel 22 is illustrated which constitutes another basic element. The wheel 22- is designed to cooperate with the pin mem her as of'the strip member l8 and is provided with a central aperture or bore 2-3 which is ofs'lightly larger diameter than the cross-sectiona'l diameter of the pin member 59 but which is of a smaller diameter than the diameter of the shoulder 25 on the pin it so that the wheel may be forced over the shoulder 2| and into rotatable relation with the pin. The pin it forms an axle for the wheel 22 while the shoulder '21 prevents removal of the wheel 22 except by the application of sufficient force axially of the pin it to constrict tliesplit ends. of thepin lfi'and'. permit'the wheel to be forced outwardly over thev shoulder 2 I. The wheel 22 is prcvided'with projecting hub or shoulder portions 2'6 and 25 which extend outwardly somewhat of the face of the Wheel on" each side. The wheel 22 is preferably provided with an annular recess 2'5 which effects a saving of material without any appreciable reduction in strength. Circurnierentially spaced apertures 27 are also provided around the outer edge of the Another basic element of the toy is illustrated in Figs. 6 and 7. This element comprises. a solid rod member 238 having a cross-sectional diameter somewhat less than the diameter of the The conholes l2, I1 and 23 in the elements In and 22. The rod 28 may be furnished in any desired length or in a number of diilerent lengths for use in the toy.

A fiat plate-like member 29 is illustrated in Fig. 3 which constitutes the fourth basic element of the toy. The plate 29 may be any desired size. or it may be provided in any: number of different sizes: In the construction shown in Fig. 1 the plate 29 is approximately square and is used to form the base of the vehicle. Plate members may be provided having other shapes. In the illustrated form plate 23 is provided with a series of spaced holes 3% adjacent the outer edges. The corner holes at are preferably spaced from each other a distance corresponding to the space between the. pins 18 on the strip member ID. The holes 30 are of a diameter sufficient to loosely receive the pins l8. Any other arrangement of the holes 3i! for construction of special assemblages may, of: course, be provided.

The fifth basic element of the toy is illustrated; in Figs. 9 and 10 and comprises. a. tubular: memher 3 IV having a longitudinal slot. 32. The tubular; member 3i is preferably formed with an outside diameter slightly larger than the diameter. of the holes i2 and ll of the strip member: I0..The. slot. fizpermitsthe. tubular member 3.! to be resiliently constricted so that it maybe insertedin. tr e holes i? or it and'adiustably held therein; This. permits thecssemblage; ofv the elements: R1,. 22 and 29 in. various rigid andadiiustabl-erelae tionships.
