COASTER WAGON WITH DISHED BODY FOR STOCKING Original Filed March 20, 1962 INVENTOR. ANTON/O p4S/N United States Patent 3,241,353 COASTER WAGON WITH DISHED BODY FOR STACKING Antonio Pasin, River Forest, Ill., assignor to Radio Steel & Mfg. Co., Chicago, Ill., a corporation of Illinois Continuation of application Ser. No. 181,006, Mar. 20, 1962. This application Jan. 6, 1965, Ser. No. 423,705 4 Claims. (Cl. 280-87.01)
This invention relates to coaster wagons and more particularly to a new and improved body construction for coaster wagons. This is a continuation of my copending application, Serial No. 181,006, filed March 20, 1962, and entitled: Coaster Wagon and now abandoned.
It is an object of this invention to produce a new and improved coaster wagon having a body construction which is free of sharp edges; having a body construction which is free of wrinkles in the corner portions; having a body construction which is capable of being stacked in telescoping relationship for maximum storage in minimum space, both in assembly and in shipment; which provides a new, novel and more attractive appearance and which is capable of manufacture in a simple and efficient manner, and it is a related object to produce a coaster wagon body of the type described having an improved edge construction which provides a smooth and wrinkle free corner construction.
These and other objects of this invention will hereinafter appear and, for purposes of illustration but not of limitation, an embodiment of the invention is shown in the accompanying drawing, in which:
FIGURE 1 is a side elevational view of a coaster wagon body embodying the features of this invention, with the wheels and handle portion illustrated in broken lines;
FIGURE 2 is a top plan view of the coaster wagon shown in FIG. 1;
FIGURE 3 is a sectional view taken along the line 3-3 of FIG. 2;
FIGURE 4 is an enlarged sectional view of the edge construction of the wagon body; and
FIGURE 5 is a perspective view which illustrates the stacking relationship made available in a wagon body of the type described.
Referring now to FIG. 1 of the drawing, illustration is made in broken lines of the wheels 10, the handle 12, turntable 14 and fork 16, all of which form conventional parts of a coaster wagon and therefore need not be more specifically defined.
The important concept of this invention resides in the construction of the steel body portion 20 of the wagon which is supported on the wheel axles by the Wheel braces 22. The body is formed of a single sheet of steel or other metal with a flat bottom wall 24 of rectangular shape and with end Walls 26 and side walls 28 which extend upwardly and outwardly from the outer edges of the bottom wall with a curvilinear fillet 30 in both whereby the upper edges of the side and end walls define a rectangular section of larger crosswise and lengthwise dimension than the bottom wall.
From the upper edge, the body portion is formed with a horizontally disposed outwardly extending flanged portion 32 and the free edge portion integral with the outer edge of the flange is rolled under the flange to define a loop 34 having its largest cross section at the outermost end with diminishing cross section as the free edge 36 extends inwardly and upwardly toward the underside of the flanged portion 32 thereby to define a smoothly looped curvilinear edge portion which is free of sharp edges, which is sufficiently well protected and confined to minimize entrapment of the dirt or other materials within the opening 38 defined between the looped end portion and the flange 32, which provides for an edge construction of high strength and stiffness, and which can be formed in a simple and easy manner without the wrinkling or creasing at the corners which are characteristic of a flat edge or a cylindrical edge construction.
The body design with a flat bottom wall 24 and outwardly and upwardly inclined side and end walls 28 provides for a dished body construction which enables a plurality of the body members to be telescoped one into the other for stacking, as illustrated in FIG. 5, whereby a considerably greater number of pre-formed bodies can be stored in a minimum of space thereby not only to facilitate manufacture but also materially to reduce the cost of storage and transportation when in a knocked-down position.
The wagon body is preferably also formed with curvilinear corner sections between the side and end walls with the corner sections increasing in radius from the bottom side to the top side. The rolled edge in the curvilinear corner portions can be formed without creases or wrinkles which are otherwise normally introduced when the edge is formed of a rounded cylindrical bead or sheet flat members.
The construction of the wagon body with side and end walls tapering upwardly and outwardly continuously from the edges of the bottom wall also functions to enhance the ease and comfort of the wagon in use, as well as to increase the capacity and apparent size of the coaster wagon. The height of the side and end walls is small by comparison with the length and width of the wagon, and the flair of the side and end walls outwardly and upwardly from the edges of the bottom wall gives to the coaster wagon the appearance of streamlining and of increased size without actual increase in the amount of material.
It will be understood that changes may be made in the details of construction, arrangement and operation without departing from the spirit of the invention, especially as defined in the following claims.
I claim:
1. A coaster wagon comprising a coaster wagon body, a pair of rear wheels mounted for rotational movement on the opposite ends of a rear axle, a pair of front wheels mounted for rotational movement on the opposite ends of a front axle, means mounting the rear portion of the wagon body on the rear axle, means pivotally mounting the forward end portion of the wagon body on the front axle for turning movement of the front axle about a horizontal axis relative to the wagon body, a fork connected to the front axle and a handle pivotally mounted on the fork for steering the wagon, said wagon body comprising a single piece of sheet metal drawn to shape with a horizontally disposed substantially rectangular flat bottom wall, end walls and side walls which extend upwardly and outwardly smoothly and without interruption from the edges of the bottom wall to define a substantially rectangularly shaped open top which is of larger crosswise and lengthwise dimension than the bottom wall, a flat horizontally disposed flange extending outwardly continuously from the upper edge of the side and end walls and an end portion contiguous with the outer edge of the flange and turned curvilinearly downwardly and inwardly smoothly and substantially without cracks or creases through an angle greater than but less than 225 and then extending in a straight line angularly inwardly and upwardly toward the underside of the flange to a point closely adjacent the side and end Walls to pro vide a rim portion that is of greater width than length and in which the corner portions between the bottom and (.9 the side and end walls are formed as curvilinear fillets and the corner portions between the end and side walls are of curvilinear shape with increasing radii from the lower end upwardly to the top.
2. A coaster wagon as claimed in claim 1 in which the body portion is formed of sheet metal of high strength and rigidity.
3. A coaster wagon as claimed in claim 1 in which the portion of the flange turned curvilinearly downwardly and inwardly extends at an angle within the range of 180 to 210 from the end of the flange.
4. A coaster wagon as claimed in claim 1 in which the curvilinearly shaped corner portions between the end and side walls are free of creases and cracks.
