Safety device for treadmills

Abstract

A safety device of a treadmill comprise a belt wrapped on user's body and having a cable with an engaging pad connected thereto. The engaging pad includes a first terminal electrically connected to a circuit of the control panel of the treadmill and a second terminal in the control panel. A magnet is received in the engaging pad and attracts a magnetically conductive member in the control panel so as to position the engaging pad. A piece movably extends through a through hole in the magnetically conductive member and a positioning hole defined through the control panel, and is pressed by the engaging pad. A switch is located in the control panel and the piece pushed an arm of the switch. The piece moves upward to release the arm of the switch to shut off the treadmill when the user falls and pulls the engaging pad away from the control panel.

1 . A safety device of a treadmill which includes a base with a running belt and a control panel connected to a top of an upright portion connected to the base, the safety device comprising: 
 a belt;    an engaging pad connected to a distal end of the cable and including a body with a magnet connected thereto, a first box connected to the body and electrically connected to the cable, the engaging pad movably connected to the control panel;    a second box adapted to be received in the control panel of the treadmill and removably and electrically connected to the first box, the second box electrically connected to a circuit of the control panel;    a magnetically conductive member adapted to be located at the control panel and being attracted by the magnet, a through hole defined through the magnetically conductive member and a piece movably extending through the through hole of the magnetically conductive member and adapted to extend through a positioning hole defined through the control panel, the piece being pressed by the body, and    a switch adapted to be located in the control panel and the piece pushed an arm of the switch.    
   
   
       2 . The device as claimed in  claim 1 , wherein the belt includes a control part electrically connected to the cable.  
   
   
       3 . The device as claimed in  claim 1 , wherein the body has two ridges extending in parallel from a top thereof and the first box is clamped between the two ridges.  
   
   
       4 . The device as claimed in  claim 1 , wherein the first box includes a plurality of first contact points extending through first apertures defined through a wall of the first box, the second box including a plurality of second contact points, a plurality of slots defined through the body and the first and second contact points being in contact with each other via the slots.  
   
   
       5 . The device as claimed in  claim 1 , wherein a cover is mounted to the body and has a ridge extending from a top thereof.  
   
   
       6 . The devices as claimed in  claim 1  further comprising two pulse detection pads connected to an inside of the belt.  
   
   
       7 . A safety device of a treadmill which includes a base with a running belt and a control panel connected to a top of an upright portion connected to the base, the safety device comprising: 
 a belt;    an engaging pad connected to a distal end of the cable and including a body with a magnet connected thereto, a first terminal connected to the body and electrically connected to the cable, the engaging pad movably connected to the control panel;    a second terminal adapted to be received in the control panel of the treadmill and being electrically connected to the first terminal, the second terminal adapted to be connected to a circuit of the control panel;    a magnetically conductive member adapted to be located at the control panel and being attracted by the magnet, a through hole defined through the magnetically conductive member and a piece movably extending through the hole of the magnetically conductive member and adapted to extend through a positioning hole defined through the control panel, the piece being pressed by the body, and    a switch adapted to be located in the control panel and the piece pushed an arm of the switch.    
   
   
       8 . The device as claimed in  claim 7 , wherein the belt includes a control part electrically connected to the cable.  
   
   
       9 . The devices as claimed in  claim 7  further comprising two pulse detection pads connected to an inside of the belt.
