The sled includes a first and second sled section integrally connected by a flexible plastic web acting as a hinge.
5 Claims, 7 Drawing Figures FOLDING SLED BACKGROUND OF THE INVENTION The present invention relates generally to a sled, and more particularly to a folding sled.
Numerous folding or collapsible sleds have heretofore been manufactured and sold. The vast majority, however, include complicated hardware which renders the folding operation cumbersome and substantially increases the weight of the sled. As such, the presently known folding sleds are unsuitable and impractical for use by small children for the sport of downhill sledding.
SUMMARY OF THE INVENTION In a principal aspect, the present invention comprises a unitary folding sled including a first and second sled section and a plastic hinge. The plastic hinge is a flexible, bendable web which integrally joins the first and second sled sections together.
It is thus an object of the present invention to provide a lightweight, readily manufactured and simply operated folding sled.
It is also object of the present invention to provide a collapsible sled wherein the sled sections are unitarily connected by a plastic hinge possessing a high degree of flexibility. regardless of temperature.
It is a further object of the present invention to provide a collapsible sled which is readily secured and locked in a folded or collapsed state.
These and other objects and advantages of the pres ent invention will become apparent in the following detailed description.

FIG. 5 is a cross-sectional view of the preferred em bodiment shown in FIG. 3 taken along 55',
FIG. 6 is a cross-sectional view of the preferred embodiment shown in FIG. 2 taken along 66; and
FIG. 7 is an enlarged, partial cross-sectional view of the preferred embodiment shown in FIG. 3 taken along 77.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to FIGS. l6, a preferred embodiment of the present invention is shown as a folding sled 2. The folding sled 2 is a unitary, molded plastic structure including a first, or forward, sled section 4, a second, or rear, sled section 6, and a plastic hinge 8. The plastic hinge 8 integrally joins the first and second sled sections 4, 6.
The first sled section 4 is hollow and includes a substantially flat, body-supporting portion II), a nose portion 12, and sidewall portions 14. As best shown in FIGS. I and 7, the first sled section 4 also includes a rearwardly and upwardly curved end portion 16 which smoothly and unitarily joins with the plastic hinge 8.
The body-supporting portion II) of the first sled sec tion 4 defines a series of longitudinal ribs 18 and grooves 20. The ribs 18 and grooves 20 extend the length of the body-supporting portion 10.
As best shown in FIG. 6, the nose portion I2 of the first sled section 4 defines a forwardly extending tip 22, having a forward edge 24, and an upwardly and forwardly curved neck 26, having an upper surface 28. The tip 22 includes an opening 30 which facilitates the transportation of the folding sled. That is, the tip 22 and opening 30 cooperatively define a carrying handle for the folding sled 2. A rope (not shown) can also be secured to the sled 2 through the opening 30.
The neck 26 includes a locking slot or groove 32 in the upper surface 28. The locking slot 32 is centrally located, i.e., equidistance from the sidewall portions 14. The significance of the locking slot 32 is discussed below.
Referring to FIGS. 4 and 5, the neck 26 also defines the origin ofa central sled runner 34. The runner 34 extends longitudinally along the underside 36 of the first sled member 4 from the neck 26 to the end portion I6. The runner 34, as shown, is centrally located between the sidewall portions I4.
The sidewall portions 14 of the first sled section 4 are slightly curved or bowed and extend substantially vertically from the edges of the body-supporting portion 10 and nose portion [2. The sidewall portions 14 incline upwardly from the end portion 16 to smoothly join the nose portion 12. The sidewall portions I4 include a pair of openings 38 which permit a user (not shown) to grasp the folding sled 2 during a sledding run.
More particularly. the sidewall portions 14 extend downwardly from the nose portion [2 and wrap around and under the body-supporting portion 10 to define a pair of outer sled runners 40, substantially parallel to the central sled runner 34. The outer sled runners 40 extend from the forward edge 24 of the tip 22 to the end portion 16 of the first sled member 4.
As best shown in FIGS. I and 6, each outer sled runner 36 includes an upwardly curved front end 42. The upturned ends 42 cause the folding sled 2 to ride upon the snow, rather than to cut through the snow, thereby decreasing the frictional drag.
The second sled section 6 includes various features which correspond to or cooperate with the previously identified and described features of the first sled section 4. These features of the second sled member 6 are identified below by the same numeral use in the description of the first sled member 4, plus 100.
As shown, the second sled member 6 is hollow and includes a substantially flat body-supporting portion III], which defines a series of longitudinal grooves 118 and ribs 120, sidewall portions I14 and an end portion 116. The longitudinal ribs 18, I18 and grooves 20, 120 of the first and second sled sections 4, 6, respectively, align and prevent the user of the folding sled 2 from transversely sliding on the body-supporting portions 10, during a sledding run. As shown in FIG. 7, the end portion 116 curves upwardly and unitarily joins the plastic hinge 8.
The second sled member 6 also includes an upwardly curved rear portion 44. The rear portion 44 defines a centrally located upwardly extending locking tab 46,
adapted to be received by the locking slot 32 as the first and second sled sections 4, 6 are folded together.
The sidewall portions 114 extend from the edges of the body-supporting portion 110 and rear portion 44. The sidewall portions 114 also incline upwardly from the end portion H6 to smoothly join the rear portion 44.
As shown, the sidewall portions 114 define, on the underside 136 of the second sled section 6, outer sled runners 140 which substantially align with the outer sled runners 40 of the first sled member 4. A central sled runner 134 also extends longitudinally along the underside 136 of the second sled member 6, substantially aligned with the central sled runner 34. The runners, I34, 140 smoothly terminate in the upwardly curved rear portion 44.
The runners 34, 36, I34, 136 decrease the surface contact between the folding sled 2 and the sledding surface or snow (not shown). Frictional drag is, therefore, also decreased, and the speed of the folding sled 2 is substantially over flat-bottomed sleds.
As shown in FIG. 7, the plastic hinge 8 is a thin plastic web. The plastic hinge 8 is substantially planar with the upper walls 48, 148 of the first and second sled sections 4, 6, respectively. As such, the first sled section 4, second sled section 6 and plastic hinge 8 present a substantially planar and continuous body-supporting surface for the user.
Preferably, the plastic hinge 8 is a synthetic plastic, such as polyethylene, polypropylene, polyurethane or polycarbonate, and possesses a high degree of flexibility, bendability and resiliency, irrespective of temperature. The plastic hinge 8 also includes an upwardly open groove 50 which extends the length of the plastic hinge 8, Le, the width of the folding sled 2. The groove 50 increases the flexibility of the plastic hinge 8. The plastic hinge 8 and groove 50 cooperatively permit the first and second sled members 4, 6 to be folded to gether from an open state, shown in FIG. 1, to a closed state, shown in FIG. 2.
In the closed state, the sidewall portions 14, H4 of the first and second sled sections 4, 6, respectively, substantially abut and the rear portion 44 of the second sled section 6 contacts the nose portion 12 of the first sled section 4 in the vicinity of the neck 26. As such, the locking tab 46 engages the locking slot 32 to detachably secure the first and second sled members 4, 6 together.
As indicated, the folding sled 2 is a unitary body, and thus, the first and second sled members 4, 6 are also a synthetic plastic. The hollow construction of the first and second sled members 4, 6 provides rigidity and also cushions" the user during a sledding run. That is, the lower walls 52, 152 of the first and second sled sections 4, 6, respectively, are flexible and will absorb small bumps, thereby providing a smoother ride than would otherwise be possible with a solid sled.
