Claims. 1

This invention relates to a new and improved toy vehicle and, more particularly, to a toy vehicle carrying a simulated cement or concrete mixer.

The primary object of the invention is to provide a toy vehicle having a simulated rotary cement or concrete mixer mounted thereon, the rotation of the mixer being accomplished simultaneously with the rotation of the rear wheels and axle of the vehicle.

A further object of the invention is the provision of a toy vehicle of the character indicated having a rotatable mixer carrying a plurality of circumferential, radially extending teeth engageable with a worm gear fixed to the rear axle of the vehicle in order to actuate the rotatable mixer upon drawing or pushing the vehicle along the ground. Another object of the invention is the provision of a, toy vehicle having a simulated rotatabe mixer associated therewith in such a manner as to permit rapid assembly without the use of pivot pins, screws or the like, the mixer housing being provided with a pair of depending, slotted bearing lugs insertable over a pair of corresponding laterally projecting lugs on the 'vehicle chassis.

An additional object of the invention is the provision of a toy vehicle having a simulated rotatable mixer tiltably mounted thereupon, the tilting of the mixer housing being accomplished by means of a lever or crank pivoted to the vehicle chassis and having a portion disposed externally of said chassis.

The foregoing objects as well as additional obgiects and advantages of the invention will be readily apparent in the course of the following detailed description taken in connection with the accompanying drawings which illustrate a preferred embodiment of the invention, and wherein:

Fig. 1 is a side elevation of a toy vehicle embodying the features of the invention;

Fig. 2 is a bottom plan view of the toy vehicle;

Fig. 3 is a side elevational view, partly in section, showing the simulated rotary mixer tilted about its pivot by means of a crank or lever sefll ed to the vehicle chassis;

Fig. 4 is a sectional view taken along line 44 of-Fig. l;

ll ig. 5 is a fragmentary detail view showing the manner of pivotally mounting the simulated rota fi mixer on the toy vehicle chassis. ;The toy vehicle may be fabricated from any :witable material; preferably a synthetic resin I and comprises a body l0 having a cab portion H, 2. preferably elongated, rectangular chassis, v portion l2 extending rearwardly of said cab portion, front wheels I3 fixed to and rotatablewith front axle l4 and rear wheels l5 fixed to and rotatable with rear axle l6.

Chassis I2 is preferably formed integrally with cab portion II and isdefined by a pair of spaced longitudinal sides I! anda transverse rear end l8. Depending from sides ll adjacent rear end i8 is a pair of vertically slotted suspension lugs IQ for rotatably retaining rear axle Hi. When the material of the toy vehicle is a thermoplastic resin, as is the case in the preferred embodiment of the invention, the rear axle is may be secured rotatably withinslotted suspension lugs I9 by constricting or swaging inwardly the material at the mouth of said lugs after the axle has been disposed therewithin and while the material is still deformable or plastic. Similarly, front axle [4 maybe rotatably housed within a pair of for-Q ward suspension lugs 20 depending from cab portion H (see Fig. 2). j

Transverse rear end member l8 of. chassis 12 is formed with a pair of late ally proiecting, semicircular pivot lugs 2|, each preferably pre-., senting a rounded upper bearing surface in order to titably support a housing 22 carrying a simulated rotatable mixer 23 in a manner to be fully described hereinbelow. Hous ng. 22 preferably com rises a rectangular base having a pair of longitudinal side members, a pair of trans verse members 25, an upri ht front end 25 and an upright rear end 21. Frontend .26 and rear end 21 preferably have reduced annular. bearing portions or shoulders 26:; and 27a respectively in order to rotatably retain therebetween the hollow cylindrical body 2 simulating a cement or concrete mixer.

'If desired, cylindrical mixer may be further suspended on an axial shaft 28secured between front end 26 and rear end 2! and passing through anraxial aperture 29 in a pair of intersecting diametral struts 3D integral with said mixer. In order to further insure anti-frictional rotation of mixer 23a a freely rotatable disc3l of slightly less diameter than the inner diameter of said mixer may be disp'osedon. shaft 28, as clearly showninFig.3.

Housing 22 carrying mixer 23 may be mounted upon chassis l2 by means ofa pair of bearing lugs 32 formed with a circular inner bearingqflg and a constricted slot 32b to allow insertion of each of said bearing lugs over a respective'lateral Divot lug 2| Of L2; The cooperation be} tween circular bearing surface 32a of bearing lugs 32 and the rounded upper bearing surface of semicircular pivot lugs 2| permits the easy assembling and tilting of mixer 23. The tilting action may be accomplished by means of a doublecrank lever 33, having an external handle portion 33a, pivotally secured to chassis 12 and normally extending longitudinally between sides l1 thereof and beneath mixer housing 22. mixer housing may be formed with an integral Y-shaped support 34 (see Fig. 2) or similar structure against which the transverse portion of lever 33 will slidably abut to tilt mixer 23 about pivot lugs 2! as clearly shown in 3. transverse member 25 of mixer housing '22 preferably carries an integral depending catch 35 having a locking recess 35a for releasably engaging lever 33 and holding said housing in tilted position.

Means are provided for accomplishing the rotation of simulated cylindrical 'mixer 23 as the my vehicle is drawn or pushed along a, su port in; surface. For this purpose a worm gear 36 is fixed centrally to and rotatable with rear axle i8 and cylindrical mixer 23 is formed with a plurality of integral circumferential. radially extendteeth 37 which are censeeut'i vei engaged by said worm g ar asrear axle it and rear wheels is are caused to rotate by pushing the toy vehiole along the ground It is thus ap arent that a toy vehicle having a 'tiltable housing carrying a rotatable simulated mixer has been provided; the rotation of the mixer being actuated in a direct and extremely "simple manner by 'ir'ieans of a worm gear fixed to the rear axle and rotatable therewith, said worm gear consecutivelyen'gaging a series of ciroiimferential, radially extending teeth formed integrally on the outerfsurface of said simulated cylindrical mixera 'It has been empirically determined that rotation of the mixer is best effected by means of a flexible, floating engagement between worm gear 36 and mixer teeth 37 exemplified in the preferred embodiment of the invention by the slotted suspens'ien lugs 13 for the rear axle i=5.
