Tilting board capable of adjusting angle of tilt

Abstract

A tilting board for a human being operated includes an operation plate, a base plate rotationally connected to the operation plate, a sliding rail fixed on the base plate, and an adjustment member. The sliding rail is fixed on the base plate and defines a plurality of pairs of opposite slots. One end of the adjustment member abuts against the operation plate and the other end of the adjustment member is positioned between one of the pairs of opposite slots. The degree of incline of the tilting board can be changed by moving the adjustment member from the pair of opposite slots to another one of the pairs of opposite slots.

         2 . The tilting board as claimed in  claim 1 , wherein the sliding rail comprises two opposite clamping pieces, the plurality of pairs of slots are arranged on the two opposite clamping pieces. 
     
     
         3 . The tilting board as claimed in  claim 2 , wherein the adjustment member defines a through hole perpendicular to the plurality of pairs of slots, an elastic member is received in the through hole, two clips respectively are positioned at two ends of the elastic member and partly received in the through hole, the end of the two clips being exposed the through hole are received in the pair of opposite slots, the two clips overcome the elastic force of the elastic member to move from the pair of slots to another one of the pairs of opposite slots. 
     
     
         4 . The tilting board as claimed in  claim 1 , wherein the sliding rail comprises a rail positioned between the plurality of pairs of opposite slots, the adjustment member is slidably positioned on the rail. 
     
     
         5 . The tilting board as claimed in  claim 4 , wherein one end of the adjustment member defines a sliding groove, the adjustment member is sleeve on the rail via the sliding groove, such that the adjustment member slide along the rail. 
     
     
         6 . The tilting board as claimed in  claim 4 , further comprising two restriction pins, the two restriction pins protruding from the base plate and positioned adjacent to two ends of rail, the adjustment member restricted to slide between the two restriction pins. 
     
     
         7 . The tilting board as claimed in  claim 4 , wherein two sides of the rail respectively defines a ditch along the lengthwise direction of the rail from one end to the opposite end, the adjustment member comprises two guiding portions opposite to each other, the two guiding portions are respectively received in the two ditches. 
     
     
         8 . The tilting board as claimed in  claim 1 , further comprising a magnet and a metal sheet, the magnet fixed on the said other end of the adjustment member, the metal sheet fixed on a surface of the operation plate adjacent to the adjustment member, the metal sheet positioned where the surface touches the magnet. 
     
     
         9 . The tilting board as claimed in  claim 1 , further comprising a handle, the handle protruding from the adjustment member. 
     
     
         10 . A tilting board comprising:
 an operation plate;   a base plate rotationally connected to the operation plate;   a sliding rail fixed on the base plate and comprising two clamping pieces, one of the two clamping pieces defining a plurality of slots; and   an adjustment member, one end of the adjustment member abutting against the operation plate, the other end of the adjustment member positioned between the two clamping pieces and partly received in one of the plurality of slots, and movable from the one slot to another slot.   
     
     
         11 . The tilting board as claimed in  claim 10 , wherein the other clamping piece defines a plurality of slots respectively opposite to the plurality of slots of the said one of the two clamping pieces, said the other end of the adjustment member is positioned between a pair of opposite slots. 
     
     
         12 . The tilting board as claimed in  claim 10 , wherein the adjustment member defines a through hole perpendicular to the plurality of pairs of slots, an elastic member is received in the through hole, a clip respectively is positioned at one end of the elastic member and partly received in the through hole, the end of the clip being exposed the through hole is received in one of the plurality of slots, the clip overcomes the elastic force of the elastic member to move from one slot to another slot. 
     
     
         13 . The tilting board as claimed in  claim 10 , wherein the sliding rail comprises a rail between the two clamping pieces, the adjustment member is slidably positioned on the rail. 
     
     
         14 . The tilting board as claimed in  claim 13 , wherein one end of the adjustment member defines a sliding groove, the adjustment member is sleeve on the rail via the sliding groove, such that the adjustment member slide along the rail. 
     
     
         15 . The tilting board as claimed in  claim 13 , further comprising two restriction pins, the two restriction pins protruding from the base plate and positioned adjacent to two ends of rail, the adjustment member restricted to slide between the two restriction pins. 
     
     
         16 . The tilting board as claimed in  claim 13 , wherein two sides of the rail respectively defines a ditch along the lengthwise direction of the rail from one end to the opposite end, the adjustment member comprises two guiding portions opposite to each other, the two guiding portions are respectively received in the two ditches. 
     
     
         17 . The tilting board as claimed in  claim 10 , further comprising a magnet and a metal sheet, the magnet fixed on the said other end of the adjustment member, the metal sheet fixed on a surface of the operation plate adjacent to the adjustment member, the metal sheet positioned where the surface touches the magnet.
