snowboard body b 2 includes an upper surface 81 and a lower surface 82 . the upper surface 81 and the lower surface 82 can be generally flat . however , opposite ends 83 , 84 of the snowboard can be curved upwardly in conventional manner . in the snowboard a 1 , the snowboard bindings b 1 are attached to the upper surface 81 . specifically , each binding frame 1 of the snowboard bindings b 1 is attached to the upper surface 81 via the base plate 3 . for this purpose , in the illustrated example , each base plate 3 of the snowboard bindings b 1 is attached to the upper surface 81 by a plurality of attaching members ( not shown ) in a conventional manner . the operation of the snowboard a 1 and the snowboard bindings b 1 should be readily apparent to a person of skill in the art from the foregoing description and the drawings . however , an example use of the snowboard bindings b 1 is briefly explained below . with the buckle mechanisms 42 , 52 initially disconnected from the hooks 426 , 526 , the user moves the assemblies 40 , 50 out of the way and steps into the binding frames 1 . when the user &# 39 ; s boots are properly positioned in the binding frames 1 , the user pulls the assemblies 40 , 50 over the boots and pivots the levers 421 c , 521 c upward to the position shown in fig1 . at the same time , the engagement portions 424 c , 524 c are positioned near the binding hooks 426 , 526 . referring to fig1 , the engagement portions 424 c , 524 c are then maneuvered behind the receiving parts 426 c , 526 c . the levers 421 c , 521 c are then rotated toward the closed position . as the levers 421 c , 521 c are rotated , they pull the traction elements 421 e , 521 e which in turn pull the engagement members 424 , 524 so that the engagement portions 424 c , 524 c gradually become locked behind the receiving parts 426 c , 526 c of the binding hooks 426 , 526 . the levers 421 c , 521 c continue to be rotated until they are fully closed ( shown in fig2 - 4 and 6 ) and the engagement members 424 , 524 are locked to the binding hooks 426 , 526 . removal works in an opposite manner , with the levers 421 c , 52 c manually rotated to the open position shown in fig1 which frees the engagement portions 424 c , 524 c from the receiving parts 426 c , 526 c . the described bindings permit connection of the engagement members to the binding hooks using one hand instead of requiring both hands . in addition , the described bindings have only two straps on each binding instead of four straps . further , the user can pre - adjust the straps 43 , 53 and the traction elements 421 e , 521 e to obtain the desired tightness . thereafter , each time that the user fastens the bindings , the same level of tightness can be achieved without requiring the user to adjust each time the user connects to the bindings . further , because the engagement members are received by the receiving part of the binding hooks , ice and snow are prevented from building up in the binding hooks . further , the binding hooks are non - rotatably attached to the binding frame . as a result , the snowboard a 1 can respond instantly to the rider &# 39 ; s movement ( for example when ollieing and spinning or applying nose or tail pressure ) and extra delay of the movement of the snowboard a 1 that can be caused by pivotally mounted straps can be prevented . fig1 is a front perspective view showing a snowboard binding according to another embodiment . the snowboard binding shown in fig1 is different from the snowboard binding shown in fig4 in that a puck or circular disk 34 is mounted on the base plate 3 . other structures in the snowboard binding in fig1 are the same as the foregoing embodiment in fig1 - 14 . the puck 34 shown in fig1 is a circular plate and can be used for adjusting an angle of the binding frame 1 on the snowboard body . for example , once the user loosens screws ( not shown ) that fix the puck 34 to the snowboard body , the user can rotate the binding frame 1 relative to the puck 34 . once the desired angle of the binding frame 1 is achieved , the user then tightens the screws of the puck 34 which clamps the base plate 3 and fixes the position of the binding frame 1 . the construction and operation of a binding frame with a puck - like disc permitting adjustment of the binding frame is known in the art . the examples disclosed in this application are to be considered in all respects as illustrative and not limitative . the scope of the invention is indicated by the appended claims rather than by the foregoing description ; and all changes which come within the meaning and range of equivalency of the claims are intended to be embraced therein .
