a rotatable cam cooperating with said channel adapted to releasably clamp said shielding panel to said channel; a lower frame adapted to be anchored to the ground extending upwardly towards a pair of spaced apart stringers, said channel comprising a U-shaped cross-section disposed between said stringers, said lower frame comprising a bottom plate adapted to be anchored to the ground with a plurality of spaced apart up-standing posts, each of said posts comprising a lower end connected to said bottom plate and an upper end connected to said stringers; and a flat plate disposed between said stringers, said channel and said upper end of said posts connected to said flat plate. ### Claim 2 (depends on 1) The dasher board assembly of claim 1, wherein said flat plate is welded to said stringers, said channel and said upper ends of said posts. ### Claim 3 (depends on 2) The dasher board assembly of claim 2, wherein said channel comprises a first leg and a second leg, and wherein said first leg is welded to one of said stringers, and said second leg is displaceable and adapted to be contacted by said rotatable cam. ### Claim 4 (depends on 3) The dasher board assembly of claim 3, wherein said rotatable cam is pinned to a bolt and comprises a cam head. ### Claim 5 (depends on 4) The dasher board assembly of claim 4, wherein said cam head is comprised of plastic. ### Claim 6 (depends on 5) The dasher board assembly of claim 5, wherein said rotatable cam comprises an aluminum pipe. ### Claim 7 (depends on 6) The dasher board assembly of claim 6, comprising a sill to prevent access to said rotatable cam. ### Claim 8 (depends on 1) The dasher board assembly of claim 1, wherein said shielding panel further comprises tempered glass. ### Claim 9 A dasher board assembly comprising: (a) a lower frame comprising (i) a bottom plate adapted to be anchored to the ground; (ii) a pair of spaced apart stringers at an upper end of said lower frame, said stringers comprising an upper and lower surface; (iii) a plurality of upstanding posts, each comprising a lower end connected to said bottom plate and an upper end connected to said lower surface of a respective stringer; (b) a U-shaped channel disposed between said stringers, said U-shaped channel comprising a first leg connected to one of said stringers and a second movable leg spaced from said other stringer; (c) a shielding panel adapted to be releasably secured to said U-shaped channel; (d) a rotatable cam disposed between said second leg of said U-shaped channel and said other stringer for cooperating with said second leg of said U-shaped channel to releasably clamp said shielding panel between said first and second legs; and (e) a sill connected to said upper surface of said stringers to prevent access to said rotatable cam, said rotatable cam is pinned to a bolt and comprises a cam head. ### Claim 10 (depends on 9) The dasher board assembly of claim 9, comprising a flat plate secured to said bottom surface of said stringers, said flat plate comprising an aperture adapted for receiving said rotatable cam. ### Claim 11 (depends on 10) The dasher board assembly of claim 10, further comprising a cam bracket secured to said other stringer, said cam bracket comprising an aperture for receiving a rotatable shaft, said rotatable shaft comprising said rotatable cam at one end thereof. ### Claim 12 (depends on 11) The dasher board assembly of claim 11, wherein said lower frame further comprises a pair of side plates at each side of said dasher board assembly, welded to said stringers and said bottom plate. ### Claim 13 (depends on 12) The dasher board assembly of claim 12, further comprising a plurality of frames connected in side by side fashion to define an athletic enclosure. ### Claim 14 (depends on 13) The dasher board assembly of claim 13, wherein said side plates of said plurality of frames are connected in side by side fashion. ### Claim 15 (depends on 9) The dasher board assembly of claim 9, wherein said shielding panel further comprises tempered glass.
