Radio controlled hydraulic disc brake for in-line skates

Abstract

One handheld radio controlled transmitter communicates with an electrical circuit board on each skate. The electrical circuit controls one battery powered dc motor linear actuator driven hydraulic pump. The hydraulic pressure created from the hydraulic pump is directly related to how much electrical current is consumed by the dc motor. The electrical current is monitored and the dc motor will move forward creating hydraulic pressure or move in reverse removing pressure. The hydraulic pressure depends on how far down or up the transmitter button is pressed. The hydraulic pump is connected to a lead screw and master piston. The hydraulic fluid travels from the master cylinder through tubing to a pair of slave cylinders on each wheel. The slave cylinders press against the disc brake pads, which press against the in-line wheel hub when the skater needs to slow or stop.

I claim:  
     
         1 . A in-line skate braking system comprising of: 
 Skate chassis that house wheels, boots, radio controlled hydraulic pumps, oil lines, air bleeder, quick release compression spring return disc brake pads, dust covers.    radio controlled handheld transmitter    
     
     
         2 . As in  claim 1  one radio controlled handheld transmitter that communicates with a radio receiver and dc motor controller electronic circuit on each skate.  
     
     
         3 . As in  claim 1  each skate has one hydraulic pump consisting electronic control circuits, one battery powered dc motor and planetary gear driven linear actuator with the lead screw connected to a master piston.  
     
     
         4 . As in  claim 1  when the hydraulic pump is activated, oil travels down thru oil lines, which connect in series a pair of slave pistons and disc brake pads located on opposite sides of each skate wheel. 
 the disc brake pads apply pressure to the wheel-hub slowing skater.  
 
     
     
         5 . As in  claim 1  when the braking system is un-activated a pair of compression return springs connected to each disc brake pad pull the disc brake pad away from the wheel relieving pressure applied to the wheel hub.  
     
     
         6 . As in  claim 1  each skates radio controlled hydraulic pump electronic circuits recognizes how far down the transmitter control button is compressed and will turn the dc motor clock wise and monitor the dc motors current.  
     
     
         7 . As in  claim 1  the further down the transmitter button is compressed, the more current is applied to the dc motor; thus applying more braking force.  
     
     
         8 . As in  claim 1  each skates radio controlled hydraulic pump electronic circuits recognizes how much the transmitter control button is released and will turn the dc motor counter clock wise and monitor the dc motors current.  
     
     
         9 . As in  claim 1  the further up the transmitter button is released, the less current applied to the dc motor; thus applying less braking force.  
     
     
         10 . As in  claim 1  each disc brake pad has a dust cover, keeping dust from disc brake pads and slave pistons.  
     
     
         11 . As in  claim 1  each compression return spring has a quick release pin for easy removal of each disc brake pad.  
     
     
         12 . As in  claim 1  the hydraulic pump is removable for easy access to fill up master cylinder with hydraulic fluid.
