The trend today is towards ski bindings with mechanical heel units in place of cable bindings which have been popular for so many years. Testing devices now available are not suitable for checking these bindings. The patent application describes two basic devices which will check these new bindings. One is adapted exclusively for checking ski bindings and the other serves an additional function as a boot press and carrier.，下面是Ski and boot relative force indicators专利的具体信息内容。
1. A device for indicating the force required to separate a boot from a ski when harnessed thereto, essentially at the toe of the boot in a direction transversely relative to said ski, including, in combination, load moving means in the form of a load bearing arm, one end of which is offset and is bearable against said boot, device setting means pivotally connected to said device and coacting with said load moving means for positioning and holding said device against said ski, an effort applying resilient arm, said load bearing arm being pivotally mounted at the end opposite said offset end and adaptable for positioning at two approximately diagonally opposite positions, one position being for engaging said boot with said offset end from the left side and the other position for engaging said boot from the right side, positioning means for positioning said arm in said two positions, a rigid indicator rod which is fixed to said device to lie parallel with said resilient arm, and a measuring scale adjacent said rod whereon the deflection of said resilient arm relative to said rod may be read.
2. The device of claim 1 which, in addition, includes booth lifting lever means, one end providing fulcrum means and the other boot reaction means, which are insertable between said boot and said ski from either side of said boot, and which exert a lifting force on said boot by levering action, said fulcrum bearing on said ski underneath said boot, said boot lifting lever means being fixed rigidly to said device at the end at which said resilient arm is fixed to project laterally from said resilient arm such that the planes of action of said resilient arm and said boot lifting lever means are approximately parallel but offset from each other.
3. The device of claim 1 which, in addition, includes boot lifting lever means, one end providing fulcrum means and the other boot reaction means, which are insertable between said boot and said ski from either side of said boot, and which exert a lifting force on said boot by a levering action, said fulcrum bearing on said ski underneath said boot, said boot lifting lever means being pivotally fastened to said load bearing arm such that said boot lifting lever means may be positioned laterally with respect to said resilient arm such that the planes of action of said resilient arm and said boot lifting lever means are approximately parallel but offset from each other.
4. A device for measuring the force required to separate a boot from a ski when harnessed thereto by the application of a force underneath said boot, said device including a resilient arm wherewith effort may be applied, boot lifting lever means, one end providing fulcrum means and the other boot reaction means, which is attached to said resilient arm at one end thereof to project laterally therefrom such that the planes of action of said resilient arm and said boot lifting lever means are approximately parallel but offset from each other, said boot lifting lever means being applicable between said boot and said ski to exert a levering action, said fulcrum bearing on said ski underneath said boot, said device having indicating means coacting with said resilient arm for indicating said force when effort iS applied to said resilient arm.
5. A device comprising the combination with a holder for at least one ski boot, of means for indicating the force required to separate a boot from a ski when harnessed thereto, said device comprising a substantially flat supporting structure against which a ski boot may be secured via clamps on said supporting structure, an effort applying resilient arm one end of which is connected to one end of said supporting structure, boot lifting lever means, one end providing fulcrum means and the other boot reaction means, projecting laterally from said end of said supporting structure such that the planes of action of said boot lifting lever means and said resilient arm are parallel but offset from each other, said boot lifting lever means being applicable between said boot and said ski to exert a levering action, said fulcrum bearing on said ski underneath said boot when said device is placed alongside said boot, said device having indicating means coacting with said effort applying resilient arm for indicating said force when effort is applied to said resilient arm.
