OOASTING DEVICE.

Applintion filed March 20, 1985. Serial Io. 18,880.

To all whom it may concem:

Be it known that I, LOUIS Gonnsonmmr, a citizen of the United States, and a resident of Melrose Highlands, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Coasting Deconnection with the accompanying drawings is a specification, like characters on the drawings representing like parts.

My invention relates to vehicular or like devices for coasting on snow or ice and adapted for use alike by adults or children for amusement, competitive sports, or conve ance purposes.

the drawings illustrating by way of example certain embodiments of my invention:

Fig. 1 is a side elevation of a device em- 90 bogging one form of my invention;

g. 2 is a plan view thereof; Fig. 3 is a vertical section, on a larger scale, taken along the line 3, 3 of Fig. 1; Fig. 4 is a cross section, upon a still larger scale, taken upon the line of Fig. 1,

looking down;

' 1g. 5 1s a view similar to Fig. 1, showing a modified construction also embodying my invention;

Fig. 6 is a plan of the device of Fig. 5.

The coasting, sledding or like device or apparatus of my invention may be made in 1 various sizes ranging from those suitable for small children up to those for use by adults. Referrin more particularly to the drawings, an first to Figs. 1 to 4, the ,device there shown comprises a plurality of shoes, runners, or runner elements includinsgg front runner 1 and a rear runner 2.

front and rear runners may be identical in shape and size to facilitate manufacture thereof in quantity, but preferably the rear runner is somewhat longer than the one in front, affording a larger supporting area.

Said runners as illustrated have a skeelike formation including up-turned portions or toes 3, 3 at the front ends and desirably one or more longitudinal ribs 4, 4 upon their under surface, of general V-shape in cross section and serving to counteract side-slip of the device.

Said front and rear runners 1, 2, Figs. 1 and 2, are arranged in tandem, being connected by a suitable frame mounted thereon. Any strong and preferably light material may be employed in f rm g the frame, such as certain woods. or metals. Preferably, however, and as herein shown the frame is composed of a small plurality, of tubular metallic members or metal tubes,

in concavo-convex or X-like. relation, and

connected at substantially the central portions of their curves, as by-the bolt or r1vet 9. The construction and arrangement of the tubular frame members as shown and described afiords a frame of great strength and rigidity, and which is symmetrical and evenly balanced. Such construction enables the device easily to be carried as by grasping it adjacent the point of connection 9 of the longitudinal tie members. When there supported the weight of the device is substantiall equally distributed to the front and to t e rear. It will be noted that the front and rear posts 5 and 6 at their. lower portions are substantially continuations of the line of curvature of the lower arcuate member 8 or tangential thereto whereby the frame is given an arch-like form of maximum strength consistent with lightness.

Mounted on the frame is a suitable seat,

10 desirably resiliently supported, herein b means of the seat post 11 which extend downwardly within the upper end of the tubular rear 0st 6 and rests upon a coil spring 12 having a suitable bearing support within the tube, herein rovided by a crosspin 13. Movement of t e seat is limited in any suitable manner, as b means of the lon 'tudinal slot' 14 in t e rear post in which rides a pin 15 projecting radially from the seat post 11. Said seat is thus connected to the rear post but permitted to yield substantially vertically relatively thereto and at the same time is prevented from objectionable transverse or turning movement.

The runners or runner elements-are attached at the lower extremities of the front and rear posts respectively in any suitable manner but preferably in such we as to permit them to have a vertical roe g or pivoted movement, whereby the coasting deirregularities of the snow or ice. Accordingly there is secured upon the upper surface of each of the runners 1, 2 a lock or lug 16, seen in detail in Fig. 3, and adapted for pivotal attachment to the frame. Desirably the rear runner 2 is permitted only a vertical rocking movement relative to the frame. The rear post 6 is accordingly formed with a vertical, longitudinal slot at its lower extremity, within which the block 16 .of the rear runner is received. A pin or bearing 17 is passed transversely through said block and the rtions or cars on 881d st at opposite s1des of the slot. Said lock 16 is of a width substantially equal to that of the slot in the rear post so as to have a close, workin fit therein when pivoting about the pin 1 while said block and ears have sufiiclent longitudinal extent to prevent relative movement between them in a transverse or horizontal plane. The described construction is strong, simple and eflicient for the purpose inten The front I'llIlIlBl'. 1 is preferably mounted for substantiall universal pivoted or rocking movement, being movable not only vertically but also transversel for steerin purposes. As best seen in ig. 8, the bloc 16 of said front runner is pivotally secured, by means of a pin 18 and 1n a manner similar to that of the rear runner, between cars 19 at the lower end of a member 20 herein shown as a sleeve upon the u per end of which the front post 5 rests. aid member 20 is fast upon or formed integrally with the lower end of a steering post 21 being herein secured thereto as by means of pins 22, 22; see Fig. 3. Said steering extends upwardly throu h the tubular front post 5 and is adapts to turn relatively thereto about its longitudinal axis. At its u per end said steering post is provided w1th suitable manual control means, herein including a steering or handle bar 23 having the hand grips 24, 25.

Desirably the steerin movement of the front runner is limits to approximately 180 degrees, 90 de ees to either side of its normal, straight nt position. For this purpose any suitable means may be employed and herein I have shown a sto 26 WhlOh may be a. pin projecting radially m the steering post and adapted to brm up against the shoulders 27, 28 on the out post 5 at one or the opposite limits of the steering swing desired for the front runner. Said pin 26 also serves to hold the steerin post and front tubular post in assembl position when the device or vehicle is being carried.

To assist the operator in mounting the coaster a mounting step 29, Figs. 1 and 2, may be provided at the rear portion of the frame, while at a. convenient point at the front of the latter a suitable foot-red; 30

may be provided, to support the feet of the operator, when desired.

In Figs. 5 and 6 I have shown a ooasti device. also embodying my invention an which 1n all respects not otherwise mentloned may be the same as that of Figs. 1 to 4. As illustrated in Figs. 5 and 6 the device or apparatus is self-supporting, that tudinal tie member 8 joins it, there is se cured a cross bar 31. Upon the opposite ends of said cross bar are mounted runners 32, 33 which in detail may be the same as the rear runner 2 of Figs. 1 to 4. Said cross bar 31 desirably terminates at its 0 posite sides in portions 34, 35 extending su stantially at right angles to the plane of the runners, so as to permit free vertical rocking movement of the latter. Said cross bar may also serve as.a mounting step, in which case the ste 29 may be omitted. Obviously, if desire and within the scope of my invention, the front runner element may also be double, or other arrangement and number of runners emplo ed.

From the foregoing it w1ll be understood that the vehicle, coaster or winter-sports device embodg ing my invention comprises a pluralit 0 runner elements connected by a suitab e strong, light frame desirably supporting a seat for the operator or rider.

referably the runners are individually rockable vertically relative to the frame, while the front runner or runners are in addition capable of pivoted movement transversely of the frame, for steer' purposes, although in some instances, as m coasting upon prepared slides such (provision for steering need not be employe My invention is not limited to the specific embodiments thereof shown and described herein.

Claims:
