This invention relates to a multi-season ski sled for use in skiing and sledding. The ski sled of this in¬ vention is not used for conventional skiing where one's feet are fixed to runners that are free to move with re¬ lation to each other, forward and backward, apart and together, and in any combination of these movements. The termxnology "skiing" in this disclosure refers to the use of a runner for sliding over the snow or the use of runners in fixed parallel or tandem relationship, or both tandem and parallel relationship, and in which the feet are not fixed to a runner or to runners.

Disclosure of Invention

The object of this invention is to provide a multi- season ski sled that can όe used for skiing or sledding. Detachably mounted wheel assemblies convert the ski sled for scooting use. The ski sled is made up of one ski mem¬ ber or several ski members. Each ski member is identical and interchangeable with another and coupling means allow two or more ski members to be formed and assembled into a rigid train of two or more ski members in tandem rela¬ tionship, or two or more ski members to be formed and assembled into rigid side-by-side relationship, or for

a combination of ski members to be formed in both tandem and side-by-side relationships. Similarly, such detacha¬ bly mounted wheel assemblies allow the ski members in tandem relationship to be converted for scooting use, the ski members in side-by-side relationship to be con¬ verted for scooting use, and, likewise, the ski members in both tandem and side-by-side relationships to be con¬ verted for scooting use. Brief Description of Drawings This object and other objects of the invention should be discerned and appreciated by reference to the draw¬ ings, wherein like reference numerals refer to similar parts throughout the several views, in which:

Fig. 1 is a side view of the ski sled with two ski members shown assembled in tandem relationship; Fig. 2 is a partial top view showing coupling means; Fig. 3 is a top view of the ski sled with wheel assemblies mounted thereon; Fig. 4 is a front view of the ski sled; Fig. 5 is a side, view of a ski member; Fig. 6 is a top view of the ski sled with two ski members shown assembled in side-by-side relationship; and Fig. 7 is a front view of the ski sled with two ski members shown assembled in side-by-side relationship. Best Mode for Carrying Out the Invention In Fig. 1 of the drawings, reference numeral 1 gener¬ ally refers to the ski sled invention shown assembled in tandem relationship. Ski sled 1 has two identical and interchangeable ski members 3 of plastic or other suit¬ able material. Ski member 3 has a single, elongated, rel- atively narrow runner 5 having an upwardly curved tip or toe 7, a flat main portion 9 and a terminating heel portion 11.

Upstanding from the lateral sides of runner 5 are toe brackets 13 having two sets of aligned holes and up- standing from the lateral sides of runner 5 are heel brackets 15 having two sets of aligned holes. As shown in Figs. 2 and 3, the toe brackets 13 fit within the heel brackets 15 and are rigidly joined together by bolts 17 inserted through such aligned holes and secured by nuts

19 engaged and tightened upon the threaded ends of bolts 17.

Each ski member 3 has a seat assembly 21 comprising a collar 23, upstanding from the bight portion of main portion 9, which complementally receives a tongue 25 de¬ pending from a hollow, tubular post 27 which is removably fixed thereto by a bolt 29 inserted through aligned holes in the tongue 25 and tubular post 27, and secured by a wing nut 31 engaged and tightened upon the threaded end of bolt 29.

A flat seat 33, with upstanding lateral hand holds 35 in fixed relationship therewith, has fixed thereto in depending relationship a post collar 37 which comple¬ mentally receives a shaft 39 in fixed relationship via a bolt 41 inserted through aligned holes in the post col¬ lar 37 and shaft 39, and secured by a wing nut 43 engaged and tightened upon the threaded end of bolt 41.

Elongated vertical guide slots 45 in tubular post 27 receive a cross pin 47 fixedly carried in transverse relationship on the bottom shouldered portion 49 of shaft 39 by interference fit through a transverse hole in shoul¬ dered portion 49.

A compression spring 51 operatively disposed between the bottom of hollow, tubular post 27 and shouldered por- tion 49, functions as a shock absorber to absorb and at¬ tenuate the impacts transmitted when runner 5 hits a bump. Cross pins 53, in transverse relationship with tubu¬ lar post 27 and extending outwardly therefrom, function as foot rests upon which a rider places his feet. Wheel assemblies 35 may be utilized with the toe and heel brackets 13 and 15 to convert a ski member 3 for use for scooting, or may be utilized with such toe and heel brackets 13 and 15 of ski sled 1, assembled in its tandem relationship, to convert same to scooting use. Each wheel assembly 55 comprises a shaft 57, two spac¬ er washers 59, two wheels 61, two washers 63 and two cot¬ ter pins 65.

For scooting use of a ski member 3, one shaft 57, two spacer washers 59, two wheels 61, two washers 63 and

two cotter pins 65 would be assembled with respect to one of the aligned holes in each of the toe and heel brackets 13 and 15, as shown in Fig. 6.

For scooting use of a ski sled assembled of two ski members 3 assembled in tandem relationship, three wheel assemblies 55 would be employed and assembled as shown in Fig. 3.

In Fig. 6 of the drawings, two ski members 3 are shown assembled in side-by-side relationship. Such assem- bly. is accomplished by a sleeve 67 which complementally receives therein opposed cross pins 53. Fixed relation¬ ship of the sleeve 67 and cross pins 53 is effected via bolts 69 inserted through aligned holes in the sleeve 67 and cross pins 53, and secured in rigid relationship by wing nuts 71 engaged and tightened upon the threaded ends of the bolts 69.

From the description of the assembly of the two ski members 3 in tandem relationship, it should be self- evident that three or more ski members 3 can be assembled in tandem relationship. From the description of the as¬ sembly of two ski members 3 in side-by-side relationship, it should be self-evident that three or more ski members 3 can be assembled in side-by-side relationship. And from the descriptions of the assemblies of the ski members 3 in their tandem and side-by-side relationships, the assembly of the ski members 3 in the combination of tan¬ dem and side-by-side relationships should be self-evident. To utilize the ski member 3, a rider simply sits on the seat 33, grasps the hand holds 35, propels himself forward and appropriately places his feet on foot rests 53. The same operation would be followed in unison when riders are utilizing the ski sled 1 of ski members 3 as¬ sembled in tandem, side-by-side, or combination relation¬ ships.
