NISPERLY TOY TRUCK 4 Sheets-Sheet 4 .W n V Z V Filed Dec. 27, 1962 M a mm m TP N m5 1 R VN m m5 MM United States Patent 3,205,616 TOY TRUCK Walter E. Nisperly, Glen Dale, W. Va, assignor to Louis Marx dz Co., Inc, New York, N.Y., a corporation of New York Filed Dec. 27, 1962, Ser. No. 247,621 4 Claims. (Cl. 46-201) This invention relates generally to toy vehicles, such as trucks, capable of being steered by tilting and, more particularly, to novel means to cause the truck to return to a level position upon removal of the tilting pressure for normal straight-line travel.
Known toy vehicles of this type have several undesirable characteristics. lf tilting pressure is applied to the vehicle to put the vehicle into a turn, the vehicle will continue to describe that turn because there is no means to cause it to return to the level position upon release of the tilting pressure. Furthermore, these toy vehicles have proven very unstable. They will not continue in a straightforward motion properly because the dirigible axle Will keep tending to turn, thus causing the vehicle to turn in one direction or the other. If the toy vehicle happens to be of the truck variety, and there is an off-balance load within the truck body with the center of gravity to one side, the vehicle will tend to turn in the direction of the resultant tilt.
Accordingly, it is a broad object of the present invention to provide a tilting dirigible toy vehicle having an automatic leveling device which will normally keep the vehicle moving in a straight and level motion.
It is a further object of the present invention to provide a toy truck capable of being steered by means of tilting pressure applied on its cab, and which, when the pressure is removed, automatically levels itself.
It is a further object of the present invention to provide a toy truck of the character described which will be easy to move in a straight direction.
It is another object of the present invention to provide a toy truck which will have a tendency to automatically level itself when carrying an unbalanced load.
It is a general object of the present invention to provide an improved toy vehicle of the type mentioned, which is of simple structure and operation, and durable and reliable in use, and which can be economically manufactured and assembled for sale at a reasonable price.
Other objects of the present invention will become apparent upon reading the following specification and referring to the accompanying drawings which form material parts of this disclosure. The invention accordingly consists in the features of construction, combinations of elements, and arrangements of parts, which will be exemplified in the construction hereinafter described, and of which the scope will be indicated by the appended claims.
In the drawings:
FIG. 1 is a bottom perspective view of a toy vehicle embodying the present invention;
FIG. 2 is a partial bottom plan view illustrating the front and rear sections of the chassis;
FIG. 3 is a longitudinal sectional view taken along line 33 of FIG. 2;
FIGS. 4, 5 and 6 are transverse sectional views taken along the correspondingly numbered lines of FIG. 2;
FIG. 7 is a front elevational view, partially cut away and partially in section, showing a tilting force being applied to steer the vehicle;
FIG. 8 is a view corresponding to FIG. 6 showing the relative position of the transverse leaf spring and the rear axle during a turn;
FIG. 9 is a partial bottom plan view of the front axle 3,295,516 Patented Sept. 14, 1%65 and front section, showing the two extreme positions of the front axle for left and right turns; and
FIG. 10 is a sectional view taken on line 101t1 of FIG. 9.
Referring now to the drawings, and more particularly to FIG. 1, a toy vehicle, such as a truck 15, is illustrated as comprising a chassis, generally indicated at 20, a cab 16, supported upon chassis 20 and having a roof 17, and a body 18. Chassis 20 includes a main frame member 21 which extends substantially the full length of the truck, a front chassis section 30, and a rear chassis section 45. Rearwardly of cab 16, main frame member 21 is formed as an upwardly opening channel 22 having flanges 23. The forward portion of main frame 21 is substantially flat and terminates at its front end in what might be termed a transversely extending box girder 24, which may be continued as a front bumper 25, although this is optional. For a purpose to be described, main frame member 21 further is formed with a pair of laterally spaced elongated slots 26 having rims extending around the periphery thereof and formed as side flanges 27 rising from each end of each slot, to substantially the center portion thereof.
Optionally, the body 18 may be a dump-type body and, for this purpose, be formed integral with or have secured thereto a bracket 19 which may be hinged between the flanges 23 of channel section 22 of main frame 21. The body 18 has its forward portion supported upon uprights 28 extending upwardly from adjacent the forward end of each flange 23.
The front chassis section 30 comprises a piece of sheet material, such as sheet metal, suitably cut and formed to shape. Section 30 has a top wall 31 which is flat so as to lie fiat against the main frame member 21, and top wall 31 is provided with a rectilinear front edge 32 adapted to abut against the box girder 24 of frame member 21. It is further formed with a rearwardly extending downwardly opening channel extension 33 having side flanges 34 substantially juxtaposed to the inner flanges 27 of the rim bounding the slots 26. The combination of the rectilinear front edge 32 engaging the box girder 24, with the channel section 33 fitting between the flanges 27 bounding the notches 26, serves to properly longitudinally align front chassis section 30 with the main frame 21 of the chassis, and such alignment is further facilitated by notches 36 adjacent the inner ends of the channel section 33. When thus properly positioned, the front chassis section 30 may be integrated with the main frame 21 by spot welding, brazing, riveting or any other suitable method.
Somewhat forwardly of the inner ends of the notches 26, an apertured ear or central plate 35 is bent centrally from the front chassis section 30 and serves as a pivoting mount for the dirigible front axle 11 which extends through the apertured ear. Section 30 is formed with a pair of side flanges or cam plates 37 which, in their forward portions extending rearwardly from front edge 32, are substantially parallel and of substantially uniform height. From a point somewhat in advance of the front wheels 14, the flanges 37 diverge outwardly to the transverse line extending through the aperture of ear 35, and then converge inwardly. The diverging and converging portions of the flanges 37 are longitudinally symmetrical relative to the axle 11 or the transverse line through the aperture of ear 35. The diverging portions of the flanges 37 increase in height, as indicated at 38, to a point somewhat forwardly of the ear 35, and then decrease in height, or slope upwardly, as indicated at 40, until the depth of the flanges is somewhat less than that ofthe forward portions thereof. The sloping portions provide cam surfaces engaged by the axle 11, as best seen, for example, in FIG 3. At the rearward ends of 4 ends 56 bent downwardly to extend through the slots 53, and these ends terminate in curved portions 55 which ride on the rear axle 13;
The rear axle 13 extendsthrough the slots 47 of the rearward cars 46 of chassis section 45, and is vertically movable in these slots while being restrained against disthe sloping portions 40, each flange 37 is formed with a forwardly and downwardly opening notch or hook portion generally indicated at 41.
It will be noted, particularly from FIG. 3, that at the points where the sloping edges 40 intersect the transverse line through the aperture of car 35, the height of the sloping portions 40 is substantially that of the uniform height of the forward portions of the flanges 37. In normal straight line travel of the truck, the axle 11 engages cams 40 at .about these points, as best seen in FIG. 3.
The aperture in the ear 35, which acts as a pivot for dirigibility of the axle 11, is somewhat larger than the axle so as to allow swinging of the axle in a substantially horizontal plane.
and the other end of the axle will correspondingly ride 'down its cam surface 40. Thus, by applying tilting pressure to either side of the cab 17, as indicated in FIG. 7, the end of the axle 11 on that side will ride upwardly and rearwardly along its cam surface 40 so as to turn the wheels toward that side to which pressure is applied. The other end of the axle will ride downwardly and forwardly of its cam surface'40. It should further be noted that the flanges 37, along substantially the entire length of the cam surfaces 40, are curved about radii which are substantially centered in the aperture of the ear 35.
Rear chassis section comprises a piece of sheet material, such as sheet metal, suitably bent to form a channel including a base 42 and flanges 43 providing rear axle supports. Base 42 is spot welded, brazed, riveted, or otherwise integrally secured to the frame or to the chassis 20, and particularly the channel portion 22 thereof;
The front ends of flanges 43 are increased in depth to form a pair of forward ears 44, and the rear ends of flanges 43 are increased in depth to form a pair of rearward ears 46. Each ear 44 or 46 is vertically slotted, as indicated at 47. Intermediate the forward cars 44, and transversely aligned therewith, an ear or tab 48 is bent out of the "base 42 and is formed with a downwardly opening slot 49. The upper or inner edge of slot 49 is somewhat below the upper or inner edges of the slots 47 in the forward ears 44. The central portion of intermediate axle 12 rests in the slot 49, and the end por tions of this axle extend through the slots 47 of the forward ears 44. 'Thus, axle 12 is able to tilt with re:
spect to the truck chassis, while being maintained in lateral alignment by the slots 47.
An important feature of the invention is the means for normally maintaining the truck level horizontally, and
for restoring it automatically to a level position when the truck has been tilted to steer the same, and after the tilting pressure has been released. As best seen in FIGS. 2, 3, 6 and 8, for this purpose base 45 is formed with a In such swinging, it will be noted that one end of the axle will ride up its cam surface 40 relatively shallow and transversely elongated offset portion 51 between the rearward cars 46 and aligned substantially with the slots in these ears. Intermediate its ends and at substantially the center line of the chassis 20 and the chassis section 45, off-set portion 51 is formed with a slot 52,'and slots 53 are formed in base 45 at either end of the off-set 51.
Off-set 51 seats a leaf spring generally indicated at 5%. Leaf spring 50 has a downwardly bent fold 54 atits center forming a bearing platewhich extends through the slot 52, and which thus serves, in cooperation with the slot 52, to center and properly position the spring 50 relative to the rear chassis member 45. Spring 50 has its placement. in a horizotnal plane. The rear axle 13 is normally biased toward the bottom ends of the slots 47 by means of the fingers 56 and, ends 55 of the leaf spring 5d, and upward movement of the rear axle 13 is limited by the center fold 54 of the spring 50. This center fold also acts as a pivot about which the rear axle 13 may rock in a vertical plane upon tilting of the truck. Normally, the rear axle is positioned slightly above the lower ends of the slots 47 and in engagement with the center fold 54.
To steer the truck, a tilting force is applied by a finger 57 (FIG. 7) on roof 17 of cab 16 over one of the wheels 14 of axle 11. The resulting force causes axle 11 to pivot and the end to which pressure is applied to ride upwardly along its cam surface 40 until it is stopped by abutment or hook 41. At this position, as shown in FIG. 10, the wheels will be turnecl in the direction (in this case for a left hand turn) to describe a turn.
As the front wheels are describing a turn, intermediate axle 12 willrock about slot 49 in ear 48 with guiding by slots 47 of ears 44.
A similar rocking motion will be described by axle 13. As seen in FIG. 8, the finger 56 of leaf spring 50 toward the side of the truck opposite to that being pressed deflect upwardly, and the other finger 56 will be deflected downwardly due to the resultant change of relative position of axle 13. This will result in'an increased reaction force being exerted against the depressed side of the truck.
When the force exerted by finger 57 is removed, leaf spring 50 will tend to cause truck 15 to resume its normal transversely level position. This in turn will cause axle 11 to resume its normal position parallel to the truck chassis, and will further cause axle 11 to assume a normal forward, straightdirection. It can also be seen that leaf spring 54) will always tend to maintain the axle 11 in a normal straight ahead position in the absence of any force on the cab. This will of course prevent axle 11 from riding along its cam surfaces 40 upon passing over any uneven surfaces in the'ground.
The leaf spring will also tend to right unbalanced loads 7 carried within the load body over the rear wheels, further permitting general straight forward motion in the absence of any directional force.
As can be seen from FIGS. 5 and 6, any relative vertical displacement, during straight and level travel, of axles Hand 13 can be easily accommodated, much in the manner of shock absorber constructions.
While aspecific embodiment of the invention has been shown and described in detail to illustrate the application of the principles of the invention, it will be understood that the invention may be embodied otherwise without departing from such principles.
