Play apparatus and elastic mechanism

Abstract

A slide play apparatus for sliding not only on the surface of snow but also on the surfaces of lawn and sand. The slide play apparatus cushions an impact from a sliding surface to a player and is excellent in operability. The play apparatus ( 1 ) includes a body part ( 2 ) having a generally cylindrical shape and including a lower board ( 7 ) which contacts with the sliding surface, an upper board ( 6 ) positioned over the lower board ( 7 ), a nose plate ( 8 ) which connects one end of the lower board ( 7 ) with that of the upper board ( 6 ), and a tail plate ( 9 ) which connects the other end of the lower board ( 7 ) with that of the upper board ( 6 ), and a blade part ( 3 ) which is provided inside the body part ( 2 ) and made of a pair of blades arranged obliquely with respect to a longitudinal direction axis of the lower board ( 7 ) so as to present a substantially X-shape in a plan view, wherein each blade is a sheet-like elastic member, and has contact parts contacted with an upper surface of the lower board ( 6 ), curved parts provided on a side of the nose plate ( 8 ) and on that of the tail plate ( 9 ), and fixation parts fixed to a lower surface of the upper board ( 6 ).

1 . A play apparatus comprising:
 a body part presenting a substantially tubular shape and having a lower board configured to be contacted with a sliding surface, an upper board configured to be positioned over the lower board, a nose plate configured to connect one end of the lower board and one end of the upper board, and a tail plate configured to connect the other end of the lower board and the other end of the upper board; and   a blade part consisting of a pair of blades configured to be provided inside the body part and to be obliquely arranged with respect to a longitudinal direction axis of the lower board so as to present a substantially X-shape in a plan view thereof, wherein each of the blades is a sheet-like elastic member, the blade comprising:   contact parts configured to be contacted with an upper surface of the lower board;   curved parts configured to be provided on a side of the nose plate and on a side of the tail plate, respectively; and   fixation parts configured to be fixed to a lower surface of the upper board.   
     
     
         2 . The play apparatus according to  claim 1  further comprising:
 handle mechanism units having handle parts configured to be vertically provided on the side of the nose plate of the upper board and to be gripped by a player; and   a seat mechanism unit configured to be provided on the side of the tail plate of the upper board and to be seated by the player.   
     
     
         3 . The play apparatus according to  claim 2  further comprising:
 a base shaft part configured to be projectingly provided from an edge of the upper board in an outer width direction;   push plates configured to be attached rotatably with respect to the base shaft part; and   brake parts configured to brake the play apparatus by a player pushing a lower end of the lower board against the sliding surface.   
     
     
         4 . The play apparatus according to  claim 3 , wherein the brake parts comprise coil springs configured to be wound around the base shaft part, one ends of the coil springs are configured to abut with the upper board, and the other ends of the coil springs are configured to abut with reverse sides of the push plates. 
     
     
         5 . The play apparatus according to  claim 2  comprising:
 the seat mechanism unit having the seat part, a base part configured to be installed at the upper board, and a hinge part configured to connect the side of the nose plate of the seat part and the side of the nose plate of the base part;   a stopper part having a hollow pipe part configured to be extendedly provided in a width direction of the upper board below the seat part, a contact part configured to be formed slantingly to the side of the tail plate from an end of a shaft part inserted in the hollow pipe toward the sliding surface, and an abutting part configured to be extendedly provided from an end of the shaft part and configured to abut with the seat part; and   a coil spring configured to be wound around the hollow pipe, and whose one end is configured to abut with a reverse side of the seat part and the other end is configured to hold the stopper part,   wherein when the player sits on the seat part, the abutting part turns around the shaft part and the contact part is separated from the sliding surface, and   wherein when the player is away from the seat part, the contact part contacts the sliding surface by a reaction force of the coil spring.   
     
     
         6 . The play apparatus according to  claim 4 , wherein a protrusion strip protrudingly provided under the seat part and a depression depressingly provided at the base part are engaged with each other. 
     
     
         7 . The play apparatus according to  claim 1  further comprising a drive mechanism unit having, at a part of the lower board, caterpillars configured to be contacted with the sliding surface. 
     
     
         8 . The play apparatus according to  claim 1 , wherein tires configured to be contacted with a the running sliding surface are attached to the blades. 
     
     
         9 . The play apparatus according to  claim 1 , wherein a width of the lower board is narrower than that of the upper board. 
     
     
         10 . An elastic mechanism provided inside and between a lower board and an upper board positioned over the lower board, and consisting of a pair of blades arranged obliquely with respect to a longitudinal direction axis of the lower board so as to present a substantially X-shape in a plan view thereof, each of the blades being a sheet-like elastic member and the mechanism comprising:
 contact parts configured to be contacted with an upper surface of the lower board;   curved parts configured to be provided on both sides of the contact part; and   fixation parts configured to be fixed to a lower surface of the upper board.
