Benefits of technology

[0025]According to the invention, it is possible to provide a play apparatus for sliding on not only a snow surface but also a lawn surface, a sand surface, and the like, which the apparatus cushions an impact to a player and is excellent in operability. Furthermore, it is possible to provide an elastic mechanism which cushions the impact.

Problems solved by technology

However, in a conventional snowboard and sleigh there exists only one board between a sliding surface and a player, and an impact received by her / him is very large.
Furthermore, because the conventional snowboard and sleigh consist of one board, there is a problem that: a player's weight movement (movement of center of gravity) is difficult to be transmitted to the board; and the snowboard and the sleigh are poor in operability.

first embodiment

[0074]As shown in FIGS. 1 and 2A to 2D, a first embodiment relating to a play apparatus 1 comprises: a body part 2 configured to present a substantially elliptical tubular shape; a blade 3 part configured to consist of an upper layer blade 3a and a lower layer blade 3b; a spring 4 configured to be provided between an upper board 6 and sliding board 7 of the body part 2; and support parts 5, 5 (see FIG. 2A) configured to be provided at a portion (center portion C) where the blade 3a and the blade 3b intersect.

[0075]As shown in FIGS. 1, 2A, and 2B, the body part 2 comprises the upper board 6 configured to be boarded by a player P, the sliding board 7 configured to be contacted with a sliding surface, a nose plate 8 configured to connect a left end of the upper board 6 and that of the sliding board 7, and a tail plate 9 configured to connect a right end of the upper board 6 and that of the sliding board 7. As shown in FIGS. 2A and 2B, the body part 2 presents a substantially elliptical...

second embodiment

[0148]In the first embodiment and the second embodiment, although the player P's feet are fixed to be substantially orthogonal to the longitudinal direction of the play apparatus 1, 71, the invention is not limited thereto. For example, as shown in FIG. 17, the player P's feet may also be fixed to play apparatuses 90, 90, respectively. At this time, the player P's feet are fixed to be parallel to longitudinal directions of the play apparatus 1.

[0149]In the second embodiment, the play apparatus 90 comprises a body part 93 having an upper board 91 and a sliding board 92, blades 94, a spring 95, and a support part (not shown). Widths of the upper board 91 and the sliding board 92 are formed slightly wider than those of the player P's feet. A length of the play apparatus 90 in a longitudinal direction thereof is formed to be shorter than that of the play apparatus 1 described above, and is about 100 cm. The player P's feet are fixed substantially over the spring 95.

[0150]In addition, be...

third embodiment

[0152]A play apparatus 110 relating to a third embodiment is different from the other embodiments, as shown in FIGS. 18A-18C, in a structure of an upper board 116 and that of a support part 130.

[0153]In the upper board 116 relating to the play apparatus 110, as shown in FIG. 18A and 18C, are formed depressions 120, 120 separated from the center portion C at a substantially equal interval. As shown in FIG. 18C, the depression 120 is formed by depressing a part of the upper board 116 toward a sliding board 117. A bottom face of the depression 120 is formed to be flat, and the player P's feet are fixed through the foot fasteners T.

[0154]Because height positions of the player P's feet can be lowered by thus providing the upper board 116 with the depressions 120, she / he easily gets on and off the play apparatus 110. Furthermore, because distances from the player P's feet to the sliding board 117 are short, it is easy to transmit a player P's weight movement to the sliding board 117, and ...

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).

Description

TECHNICAL FIELD[0001]The present invention relates to a play apparatus for sliding on surfaces of snow, a lawn, and the like.BACKGROUND ART[0002]As a play apparatus for sliding on a slant by a player's own weight, a snowboard and a sleigh for sliding on a surface of snow are mainly known. For example, a conventional snowboard consists of one board formed like a substantial ellipse in a plan view thereof a lower surface thereof is used as a sliding surface and an upper surface thereof is used as a boarding surface of a player. The player moves her / his weight (movement of center of gravity), thereby transmits a force to the board, and can make right and left turns, and the like (see Japanese Patent Laid-Open Publication No. 2004-160095).DISCLOSURE OF THE INVENTIONObject of the Invention [0003]However, in a conventional snowboard and sleigh there exists only one board between a sliding surface and a player, and an impact received by her / him is very large. Furthermore, because the conve...
