INVENTOR ROBERT W. PATCH United States Patent 3,091,888 TOY TRUCK Robert W. Patch, 4118 Woodbine St., Chevy Chase, Md. Filed June 11, 1962, Ser. No. 201,628 14 Claims. (Cl. 4617) The present invention relates to toy trucks, more particularly of the type that may be readily assembled and disassembled by a child.

Accordingly, it is an object of the present invention to provide improvements in toy trucks that can be readily assembled and disassembled by a child.

Another object of the present invention is the provision of a toy truck that is convertible from one type of truck to another type of truck using only the same parts for each type of truck,

Finally, it is an object of the present invention to provide a toy truck that will be relatively simple and inexpensive to manufacture, easy to assemble and disassemble and to convert from one type of a truck to another, and rugged and durable in use.

Other objects and advantages will become apparent from a consideration of the following description, taken in connection with the accompanying drawings, in which:

FIGURE 1 is an exploded perspective assembly view of a toy truck according to the present invention with p the truck body removed;

FIGURE 2 is a view similar to FIGURE 1 but with the truck body in place and the cab removed;

FIGURE 3 is an elevational view of the toy truck of the present invention in the form of a dump truck with the dump body raised;

FIGURE 4 is a view similar to FIGURE 3 but showing the toy truck of the invention in the form of a closed van truck;

FIGURE 5 is an enlarged view in cross section of a portion of FIGURE 3; and

FIGURE 6 is an enlarged view in cross section of a portion of FIGURE 4.

Referring now to the drawings in greater detail, and first to FIGURE 1 thereof, there is shown a toy truck having a chassis 1 comprised of a flat bottom 3 in the form of a plate having side members in the form of upwardly extending side edges or sills 5. Side sills 5 are interconnected at their forward ends by a front edge or end sill 7 that extends upwardly from bottom 3. A pair of axially aligned openings 9 extend through each of sills 5. Bottom 3 extends to the rear and terminates in a rear edge 11; but side sills 5 extend rearwardly beyond rear edge 11 and terminate in cantilevered rear ends. Bottom 3 thus extends between and rigidly interconnects side sills 5 except at the rear ends of sills 5.

A drivers cab 13 is removably mounted on the front of chassis 1 between side sills 5 and behind front end sill 7. Preferably, cab 13 is in contact with sills 5 and 7. Cab 13 has a closed top 15 and an open bottom and four lateral sides 17. The three front sides are provided with windows 19 that open through sides 17 into the empty interior of cab v13.

Cab 13 is also provided with a pair of aligned recesses in the form of openings 21 through the opposite lateral sides 1-7 thereof. Openings 21 are spaced between the front and rear sides 17 of cab 13 and above the bottom edge of cab 13. Openings 9 and 21 are in registry with each other when cab 13 rests on bottom 3 in contact with sills 5 and 7. The truck has removable front wheels 23 that are supported on axles 25 that pass through openings through the wheels and through the aligned openings 9 and 21 on each side of the truck. Axle 25 has an enlarged head 27 that limits inward movement of axle 25 and that provides a thumb piece for pushing axle 25 through openings 9 and 21. Preferably, wheels 23 are loose on axles 25 but axles 25 have a snug frictional fit with openings 9 and 21.

Referring now to FIGURE 2, the truck is seen to include .a truck body 29. In the orientation of truck body 29 shown in FIGURE 2, the top of the truck body is open and the bottom 31 is closed. In this arrangement, the truck is an open-topped dump truck. The truck body includes side walls 33 and

end walls

35 and 37. In the orientation of FIGURE 2, end wall 35 is the rear end wall and is mounted by a hinge 39 at its lower edge on the rear edge of bottom 31. End wall 35 is thus mounted for vertical swinging movement about a horizontal axis at the lower rear of the truck body when the truck body is positioned as in FIGURE 2. Spring friction clips 41 carried by the upper outer corners of end wall 35 engage yieldably with the upper rear inner corners of side walls 33 releasably to retain end wall 35 closed.

Truck body 29 has a pair of aligned recesses in the form of first openings 43 through opposite side walls 33. Openings 43 are not only spaced a distance x from the rear ends of side walls 33 but also are adjacent but spaced above bottom 31 in the orientation shown in FIGURE 2. Truck body 29 is also provided with recesses in the form of second openings 45 therethrough that are aligned with each other and extend through opposite side walls 33 and are spaced a distance y from front end wall 37 and are adjacent but spaced below the upper edge which marks the open top of the truck body in the orientation shown in FIGURE 2. The vertical distances by which

openings

43 and 45 are spaced respectively above the lower edge and below the upper edge of the side walls 33 are the same; but the distances x and y by which

openings

43 and 45 are spaced from

end walls

35 and 37 respectively are different from each other. Distance y is substantially longer than distance x.

Adjacent their rear ends, side sills 5 are provided with first openingsg 47 therethrough, the openings 47 being aligned with each other on opposite sides of chassis 1. Sills 5 are also provided with second openings 49 therethrough that are aligned with each other on opposite sides of chassis 1.

Openings 47 are to the rear of openings 49 a distance equal to the difference in lengths x and y. Openings 47 are spaced above the plane of the upper surface of bottom 3 a distance equal to the distance 'by which openings 43 are spaced above the lower edge of side walls 33 as seen in FIGURE 2; and openings 49 are spaced above bottom 3 a distance equal to the distance by which openings 45 are spaced below the upper edge of side walls 33. The distances by which

openings

43 and 45 are vertically spaced from their adjacent horizontal edges of side walls 33 are not necessarily equal, but in each case they are less than the height of side sills 5.

An important feature of the invention is the relationship between the position of rear edge 11 of bottom 3 and

openings

47 and 49. In the illustrated embodiment, openings 47 are to the rear of the vertical plane that includes edge 11, while openings 49 are disposed forwardly of that vertical plane, for .a purpose that will shortly appear.

The truck also has rear wheels 51 detachably mounted on the chassis by means of axles 53 having enlarged heads 55 that serve as thumb pieces as described in connection with the front Wheel axles.

Another very important feature of the invention is that axles 53 are insertable through rear wheels 51 and selectively through

openings

47 and 43; or when truck body 29 is turned upside down and end for end, axles 53 are insertable through rear wheels 51 and

openings

49 and 45. In the first case, as indicated in FIGURE 3, the truck 3 body is in the position of FIGURE 2 and the truck serves as a dump truck. The truck body can swing about aligned axles 53 into the position shown in FIGURE 3. Because openings 47 are to the rear of rear edge 11 of bottom 3, there is no interference between the closed bottom 31 of the truck body and the bottom 3 of the chassis. This relationship is best seen in FIGURE 5, in which it can "be clearly seen that'the location of openings 47 to the rear of edge 11 is desirable as permitting clockwise swinging movement of bottom 31 as seen in FIGURE 5 without interference with bottom 3. Axles 53 should be snug in openings 47 and loose in openings 43, or snug in openings 43 and loose in openings 47.

By contrast, when the truck body is turned upside down and endfor end as seen in FIGURE 4, then the open or free edges of side walls 33, seen at the bottom of side walls 33 in FIGURE 6, interfere with the bottom 3 and do not permit clockwise swinging movement of the truck body. This is because the axles 53 are then inserted through wheels 51 and through openings 49, which are disposed forwardly of openings 47. Axles 53 can then be snug both in openings 49 and in openings 45.

The important relationship of

openings

47 and 49 is thus seen to be that they be spaced apart along sills 5. Preferably, openings 47 are behind edge 11; but of course openings 47 can be moved forward of their illustrated position by moving openings 43 closer to bottom 31 or to end wall 35 or both. Thus,

openings

47 and 49 are so related to bottom 3 and especially rear edge 11 thereof that bot-torn 3 prevents substantial swinging of body 29 in FIGURE 4 but permits it in FIGURE 3. However, as best seen in FIGURE 5, bottom 3 with-its rear edge 11 performs the further function of preventing excessive swinging'movement of truck body 29 relative to the chassis; and in the illustrated preferred form, the center of gravity of truck body 29 is behind the vertical plane of axles 53 in FIGURES 3 and 5 when bottom 31 contacts edge 11, so that the full dump position (not shown) of the truck body is an equilibrium position. a

It is also to be noted in connection with FIGURE 4 that when the truck body thus forms a closed van, the swingable end wall 35 is disposed at the front, quite close behindcab 13, and binge 39 is at the upper forward corner of the truck body. End wall 35 is thus efliectively kept closed, because its free edge adjacent spring clips 41 is at the lower forward corner of the truck body, which is hidden between sills 5 and behind cab 13.

It should also be noted-that the positioning of openings '43 and 45- on the truck body diiferent distances x and y from their adjacent end walls, coupled'with the provision that

openings

47 and 49 be spaced apart lengthwise of sills 5 a distance equal to the differences between distances x and y, assures that the truck body will assume about the same position lengthwise of the chassis in either of its alternate positions.

Furthermore, it is to be noted that front end sill 7 not only serves as a means for interconnecting and bracing the inwardly extendingsleeves or sockets thatwould thus project into the interior of truck body 29 would detract from the attractiveness of the toy. Therefore, it is preferred that the material of the truck be relatively thick such as fiberboard or Wood. It is also possible to provide "plates (not shown) secured to theinner sides of the cab andtruck'body

adjacent openings

21, 43 and 45 to close those openings and leave sockets with closed inner ends, and so to proportion the length of axles 25. and 53 that when the axles are pushed in to their respective assemblies, those plates will con-tact and stop the inner ends of the axles before

heads

27 or 55 press'wheels' 23 or 51 so tightly against sills 5 that the wheels cannot freely turn.

The term recesses as used in this application and the appended claims thus covers openings through the cab or truck body, or openings that-are closed by plates or the like, or sleeves whether they are open or closed at their inner ends, among otherconstructions.

In use, the person playing with the toy truck may pull out or replacethe axles 25 and thereby assemble and disassemble the frontend of the truck with its removable wheels 23 and cab 13, or he may pull out and replace the rear wheel axles 53, turning the truck body upside down and end for end selectively to make the truck a closed van truck or a dump truck, with the selection of

appropriate openings

47 or 49 in registry with

openings

43 or 45 depending on which position the truck body is in. When in dump truck position, the person playing with it may also swing the truck body up and down as indicated in FIGURE 3 and may pull open and close the door provided by rear wall 35. In this 'Way, the truck may be'made into several different kinds of trucks by use of exactly the same pieces in each case.

From a consideration of the foregoing disclosure, it

-will be obvious that all of the initially recited objects of 'the rear of the rear'edge of the bottom, a truck body, rear wheels on the truck, and axle means on which the rear wheels are mounted, the axle means mounting the truck body on the side edges for vertical swinging movement side sills 5 so that they cannot be broken by outward and downward twisting, but also serves as a simulated bumper as seen in FIGURES 3 and 4. Similarly, heads 27 and 55 not only serve as thumb pieces but also simulate hubcaps.

It will also be appreciated that the toy truck of the present invention can be made of a variety of materials. Preferably, the materials should be of a thickness such that the axial extent of the

openings

9, 47 and 49 on the sills, taken with the

openings

21, 43 or 45 in registry therewith, should be suflicient to give good support for the truck on the cantilevered pins provided by

axles

25 and 53 through

wheels

23 and 51. If the device is made of thin sheet metal, for example, then the axial extent of

openings

9 and 21, and 47 or 49 and 43 or 45, should be increased by providing inwardly extending sleeves (not shown) about

openings

21, 43 and 45; but this provision is less preferred than using suflioiently thick material, for

about a horizontal axis disposed to the rear of the rear edge of the bottom.
