2 Claims.V (C1. 280-11.13)

Other objects of the present invention are to provide a skihaving a high degree of flexibility, which is of simple construction, inexpensive to manufacture and ecient in operation.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection n with the accompanying drawing, in which Fig. 1 is a top plan view of a ski construction according to the present invention.

Fig. 2 is a longitudinal sectional view taken through the ski and on line 2-2 of Fig. 1.

Fig. 3 is a top plan view of a modified form of the invention.

Fig. 4 is a longitudinal sectional view of the ski shown in Fig. 3 and taken on line 4-4 thereof. v

Referring now particularlyv to Figs. 1 and 2, l0 and Il respectively represent upper and lower plates which are turned up at their forward ends as indicated at l2 and I3 respectively. Bottom plate I I has a small member I4 secured to its top face and into this member there is extended a 2 connected to the bottom plate 22 and from this member there extends outwardly bolts 28 for receiving the foot plate of the ski. The plate 24 has tapered front and rear ends as indicated at 3| and 32. The rubber is formed to receive the tapered ends of the plate 24 and extend along the opposite sides thereof. The rubber 23 accordv ingly extends along the tapered portions to the opposite sides thereof as well as over the top and bottom of the same.

While various changes may be made in the Vdetail construction, it shall be understood that such changes shall be within the spirit and scope of the presentJ invention as dened by the appended claims.

` I claim:

l1. In a ski, a top plate, and a bottom plate spaced from said top plate, a rubber strip extending longitudinally through the ski, said strip plurality of bolts I5 to which the top construc- Y tion or foot plate, not shown, may be connected.

Between the plates l0 and Il there extends a long rubber strip I6 having an opening I1, the strip I6 being cemented or otherwise secured to the plates I0 and Il. As the ski is flexed, the rubber will be stretched and tend to pull the ski to its original shape when the pressure is released.

Referring now particularly to Figs. 3 and 4, there is provided top and bottom plates 2| and 22 between which there is extended a rubber element 23 having a rigid plate 24 embedded in the same. The rubber will accordingly extend on the opposite top and'bottom sides of the plate 24 as indicated at 25 and 26. These portions of the rubber will be stretched as the ski is flexed and will cause the ski to assume its original shape when the pressure is released.y -A member 211s being interposed between said plates and secured thereto, and a stiifening plate embedded in said strip, the longitudinal axis of said plate and the longitudinal axis of said strip being coincident, said plate being of less length than said strip ard having its ends spaced from the ends of said s rip.

2. In a ski, a top plate, and a bottom plate spaced from said top plate, a rubber strip extending longitudinally through the ski, said strip being interposed between said plates and secured thereto, a stiffening plate embedded in said strip, the longitudinal axis ofsaid plate and the longitudinal axis of said strip being coincident, said plate being of less length than said strip and having its ends spaced from the ends of said strip, said stiffening plate having tapered ends, and said rubber strip extending along the side of said tapered ends of the stiffening plate.

EVERETT M. HUNT.
