Foot-operated hydraulic power source for emergency hydraulic tools

A foot-operated and readily portable hydraulic power source for supplying hydraulic fluid pressure to hydraulic tools, said power source comprising:

• a generally planar base member;
• a hydraulic pump fixedly mounted relative to said base member, said hydraulic pump including a hydraulic piston in sealing engagement with a hydraulic cylinder, said hydraulic cylinder adapted to contain hydraulic fluid, said hydraulic piston adapted to create hydraulic pressure by movement of said hydraulic piston against said hydraulic fluid;
• hydraulic fluid reservoir means for storing a suitable volume of hydraulic fluid, said hydraulic fluid reservoir means including means for securing said reservoir means about a portion of an operator's torso;
• a fluid conduit to supply the hydraulic fluid from said reservoir means to said hydraulic pump;
• another fluid conduit to deliver the hydraulic pressure from said hydraulic pump to a hydraulic tool;
• foot-engaging means for retaining an operator's foot therein, said base member and said foot-engaging means being hingedly secured at ends thereof opposite to said hydraulic pump for pivotable movement of said foot-engaging means relative to said base member, said foot-engaging means comprising a planar foot-engaging member of shorter dimension than said base member and in generally overlying relationship therewith, a heel engaging portion attached to the foot-engaging member near one end thereof, an arm projecting outwardly and rearwardly from the heel engaging portion for operative attachment to said hydraulic piston, and means for securing the operator's foot relative to said foot-engaging member;
• resilient biasing means disposed between said base member and said foot-engaging means for urging said foot-engaging means away from said base means;
• and
• retainer means extending between said base member and said foot-engaging means for limiting the displacement of said foot-engaging means from said base member by said biasing means.

A portable foot-operated hydraulic power source for supplying hydraulic fluid pressure to hydraulic tools, said hydraulic power source comprising:

• base means;
• pump means fixedly mounted relative to said base means, said pump means including a hydraulic piston in sealing engagement with a hydraulic cylinder, said hydraulic cylinder adapted to contain hydraulic fluid, said hydraulic piston adapted to create hydraulic pressure by movement of said hydraulic piston against said hydraulic fluid;
• fluid conduit means to deliver the hydraulic pressure from said pump means to a hydraulic tool;
• foot-engaging means for retaining an operator's foot therein, said foot-engaging means being movable relative to said base means and operatively connected to said hydraulic piston for movement thereof to create hydraulic pressure;
• said pump means being mounted at one end of said base means, and said foot-engaging means comprising a planar foot-engaging member of shorter dimension than said base means and in generally overlying relationship therewith, a heel engaging portion attached to the foot-engaging member near one end thereof, an arm projecting outwardly and rearwardly from the heel engaging portion for operative attachment to said hydraulic piston, and means for securing the operator's foot relative to said foot-engaging member.
