My invention has for its object a toy assuming the general shape of a truck or the like vehicle body and containing at least detachably the running gear that the child handling the toy will subsequently secure in its operative position on the body of the vehicle.
According to a main object of my invention, the toy has a running gear including at least one axle, wheels and members for holding the wheels in position on the axle, said wheel-holding members having at least one central perforation adapted to register with the cross-section of the axle and carrying connecting parts adapted to engage the corresponding wheels whereby the child may use said wheel-holding members for mounting the wheels perpendicularly to the axle.
I have illustrated by way of example in accompanying drawings two preferred embodiments of my invention. In said drawings:
Fig. 1 is a perspective view of a toy in the shape of a truck, the running gear being mounted in its operative position;
Fig. 2 is a perspective view of the body of the truck laid sideways with its terminal flaps in their open position;
Fig. 3 illustrates the rear end of the body with the corresponding flaps;
Fig. 4 is a partial view of an axle carrying a wheel;
Fig. 5 shows a wheel-holding member;
Figs. 6 and '7 are perspective views of a wheelholding member intended for use in a second embodiment of m invention.
The cardboard toy illustrated in Fig. 1 assumes the shape of a truck body provided at its front end with a cover the upper part of which is sloping and is constituted by a flap I closing the truck body. This flap I carries along its free edge and on its inner surface an adhesive strip 2, whereby said flap is secured to the lower closing flap 4 when the truck body is mounted on its wheels to form a complete toy truck. The body is also provided at its front and to either side thereof with two pairs of lateral flaps 5 and 6.
During the formation of the truck out of the blank sheet including the above mentioned flaps, the two lower flaps 6 are folded over each other perpendicularly to the side walls of the body after which the lower flap 4 is closed over said superposed fisps 6, the oblique extension 4 of said lower flap then engaging the gap between the side walls of the package forming the body ,of the truck so as to prevent said walls from meeting each other, which would make the truck body collapse. This being done, the upper lateral flaps 5 are folded over each other on the outside of the above mentioned extension 4' and in contact therewith. Lastly, the large front flap or cover I is folded over the system including the folded flaps 5 and over the lower section of the lower flap 4, the adhesive strip 2 on said large flap I being glued to said lower section of the flap 4.
The flaps l, 5 and 6 form the normal opening and closing means for the truck which is intended to serve for, packaging goods. At the rear end of the truck body are located two lateral flaps or panels 8 and 9, an inner panel [0 formmg an extension ofthe bottom ll of the body and lastly an outer cover or flap 12 the outer edge of which extends in the shape of a folded lug l3 adapted to be glued to the bottom of the body so as to close the latter.
On the bottom ll of the body are drawn four trapezoids IS the large bases of which are parallel to the sides of the truck body. The trapezoids define the cutting end folding lines along which the child may form lugs ll folded at underneath the bottom of the body and provided with stiffening edges at l8. The sidewalls of the body are to be out along arcuate lines 19 that are surrounded by drawn lines simulating the mudguards. The child will provide in each lug I! a circular perforation 20 along a previously drawn and embossed line whereby a system of two opposite lugs I! is provided, the perforations 20 in which form associated bearings for the prismatic axle to be described hereinafter.
Turning to Fig. 3, it is apparent that the inner lateral flap 8 is provided with two series of four dotted lines 22 arranged in equidistant parallel relationship, and between the medial lines of each series is drawn an equilateral triangle 23. The flap 8 is to be out along the outer lines of each series of lines 22 so as to produce two flat strips that it is sufficient to fold twice along the medial lines 22 so that the opposite edges of the strips come into contact, this providing two prismatic axles the cross-sections of which assume the shape of an equilateral triangle as illustrated in Fig. 4. The lines 22 form the ridges of the assembled prism designated by the reference number 24 in Fig. 4.
To obtain more resistant axles, it is possible to provide series of five or more equidistant parallel lines 22, which allows obtaining a double thickness for one or more of the lateral surfaces defining the hollow prismatic axle.
Four equal circumferences 26 drawn on the lower flap l0 and partly cut out before use, correspond to the external outlines of the truck wheels. An equilateral triangle'Zl is drawn at the centre of each circumference 26 and defines the central perforation that is to be executed in the wheel to allow the latter to be mounted over the prismatic axle 24 the triangular cross-section of which fits inside said perforation.
The second lateral rear flap 9 (Fig. 3) carries,
r 28 fitted over the axle'24.
polygonal outline of the axis, the wheels 26 the folding of the lugs H.
3 when folded onto a plane surface, the outline of the wheel-holding members 28 one of which is shown separate in Fig. 5. Said wheel-holding member 28 the general shape of which is triangular, is provided with acentral perforation 29 adapted to correspond with the triangular cross-section of the prismatic axle 24. The sides of the central triangular part of the member 28 are associated with lugs 38 that may be folded obliquely with reference tothe plane of the central part and that include each a tenon 3| adapted to engage a slot 32 in the wheel 28 (Fig. 4). The wheels 25 are thus held in planes perpendicular to the axis of the axle 24 through their triangular perforations 2'! and through the bearings provided by the wheel-holding members By reason of the revolve in unison with the latter which is in its turn guided in its rotation inside the circular perforations 28 forming bearings in the lugs 17.
The wheels 26 and the members 28 are fitted over the ends of the axle 24 previously inserted in the lugs 17, until the triangular bases of the members 28 abut against the bearings i? if said members 28 are mounted on the inside of the Wheels.
' bottom H of the body is provided with projections 50 as shown in Fig. 2 that are out out before These projections acting as stops prevent the projecting parts of the tenons 3! on the wheel-holding members proalready be cut out partly and held temporarily in position by bridge members that are easily severed when required.
Inthe second embodiment illustrated in Figs. 6
a and '7, the wheel-holding member includes an outer disc 35 perforated at 35 to match the crosssection of the axle, three connecting lugs 3? adapted each to engage a slot in the corresponding wheel 26 and a transverse bearing element 38.
This latter element is constituted by a fourth lug that is longer than the first three lugs and that is bent at its ends 39 and 33 so as to lie in register with the inner surface of the wheel and to form a further bearing element provided with a perforation 41 adapted to carry the axle 24 with some friction.
When the running gear is completely mounted, each bearing element 38 serves for suitably spacing the bearing lug H with reference to the actual wheel 26, the disc 35 located on the outside of the wheel assuming substantially the appearance of a Wheel hub cap.
Instead of being constituted by a fourth lug on the disc 35, the transverse bearing element 38 may constitute an independent twice folded member provided with terminal lugs engaging slots formed in the wheel.
