Description

  The present invention relates to a sliding play equipment that slides on a snow surface, a turf surface or the like.

  An example of a sliding playground equipment that slides on a slope by the player's own weight is a snowboard that slides on a snow surface. Conventionally used snowboards are composed of a single plate formed in an oval shape in plan view, and the lower surface of the plate is used as a sliding surface and the upper surface is used as a boarding surface on which a player rides. The player can make left and right turns by transmitting weight shift to the board (see Japanese Patent Application Laid-Open No. 2004-160095).

However, since most snowboards are made of a single plate and have a substantially oval shape in plan view, the feeling that the player receives from the snow surface, the sliding comfort, etc., are not much different. In addition, since only one board is interposed between the snow surface and the player's foot, the impact on the player's foot from the snow surface was very large.
The present invention was made to solve such a problem, and is a play equipment that slides on a slope such as a turf surface or a sand surface, not limited to a snow surface, and alleviates the physical burden on the player, It is an object of the present invention to provide a sliding playground equipment that can obtain a sliding feeling different from conventional sliding playground equipment and a blade that is suitable for reducing impact.

A sliding plate having a first edge at the outer end and sliding on the slope; an upper plate positioned above the sliding plate; a nose plate connecting one end of the sliding plate and one end of the upper plate; It consists of a tail plate that connects the other end of the sliding plate and the other end of the upper plate, and has a substantially cylindrical shape.

  According to this invention, the nose plate and the tail plate function as a cushion because the nose plate and the tail plate are connected to each other with the nose plate and the tail plate. , Can reduce the impact on the player's feet. In addition, by reducing the impact received on the player's feet, it is possible to obtain a different sliding comfort and feel than before.

  Moreover, this invention may have a 1st side curve in the said outer side edge part.

  According to this invention, by forming the first side curve at the outer end portion of the sliding board, the first edge having the curve that is disposed at the outer end portion captures the sliding surface, so that the turn is smoothly performed. Can do.

  Further, the present invention provides a projecting portion that projects outward from the outer end portion of the sliding plate, and a second side that is formed at the outer end portion of the projecting portion and has a curvature larger than the curvature of the first side curve. A blade having a curve and a second edge disposed at the outer end of the protrusion may be brought into contact with the upper surface of the sliding plate.

According to this invention, a braid | blade has a protrusion part provided with the 2nd edge located further outside rather than the 1st edge provided in the outer side edge part of the sliding board. Since the blade is in contact with the upper surface of the sliding board, when the player moves the body weight, the sliding board and the blade are tilted, and the second edge disposed on the protruding portion catches the sliding surface. Since a second side curve having a larger curvature than the first side curve of the sliding board is disposed at the outer end portion of the protruding portion, a sharper turn can be performed. Since the first edge or the second edge can be properly used depending on the movement of the player's weight, a variety of turns can be performed.
In the present invention, a blade refers to a plate that guides a turn by contacting a sliding surface.

  Further, the present invention includes two blades disposed obliquely with respect to the longitudinal axis of the sliding plate so as to exhibit a substantially X shape in plan view, and the blade is brought into contact with the upper surface of the sliding plate. A contact portion, a curved portion provided on the front end plate side and the rear end plate side, and a fixing portion fixed to the lower surface of the upper plate.

Here, in the description of the present invention, it is assumed that the left foot comes to the traveling direction side.
According to this invention, the two blades provided with the curved portions on the nose plate side and the tail plate side are disposed obliquely with respect to the longitudinal axis direction of the sliding plate so as to exhibit an X shape in plan view. That is, one blade is disposed from the left toe side to the right foot heel side. The other blade is disposed from the left heel side to the right foot toe side. Thus, for example, when the weight is moved to the left foot toe side, the space between the fixing portion and the contact portion on the left foot toe side is compressed, and the reaction between the fixing portion and the contact portion on the heel side of the right foot is released. The That is, the weight of the player can be smoothly moved by the elasticity of the blade.
Further, since the curved portion of the blade serves as a cushion, the impact received on the player's feet can be further reduced.

  Moreover, this invention may provide a bearing tool in the location where the said sliding board, the said blade, and the said blades contact.

  According to this invention, since the friction which arises in the sliding board and blade which contact can be reduced, a blade can be slid smoothly.

  In the present invention, an elastic body may be interposed between the sliding plate and the upper plate.

  According to this invention, since the cushioning property of the sliding plate and the upper plate is enhanced by interposing the elastic body between the sliding plate and the upper plate, it can flexibly cope with the vertical load received by the sliding plate and the upper plate. be able to.

  Moreover, this invention may make the width | variety of the said sliding board narrower than the width | variety of the said boarding board.

  According to this invention, the frictional resistance with the running surface is reduced, the running speed can be increased, and the range in which the body weight is transmitted is reduced, so that the turn can be easily performed.

  Further, the present invention is two blades disposed obliquely with respect to the longitudinal axis of the sliding plate so as to exhibit a substantially X shape in plan view between the sliding plate and the upper plate positioned above the sliding plate. A contact portion that contacts the upper surface of the sliding plate, a curved portion provided at both ends of the contact portion, and a fixing portion that fixes both ends of the blade to the lower surface of the upper plate, and an outer end of the sliding plate Protruding portions that protrude outward from the portions are provided.

  According to this invention, since the blade is interposed with the curved portion between the sliding plate and the upper plate, the impact applied to the sliding plate and the upper plate can be reduced.

  According to the present invention, in a sliding playground equipment that slides not only on a snow surface but also on a turf surface, a sand surface, etc., the burden on a player's foot is eased and a sliding feeling different from that of a conventional sliding playground equipment is obtained. Can do.

That is, when the weight of the player P acts perpendicularly to the sliding board 7, the second edges 45 a and 45 c disposed on the blade 3 do not come into contact with the sliding surface S. The entire surface can touch the running surface and slide straight.
As shown in FIG. 13, when the player P moves his / her weight to the left foot along the traveling direction, the space between the upper plate 6 on the left foot side and the sliding plate 7 is compressed (arrow 55) and the blade 3 Due to the reaction, the space between the upper plate 6 on the right foot side and the sliding plate 7 is opened (arrow 56), so that the weight can be moved smoothly.

(When making a turn)
As shown in FIG. 14, the sliding play equipment 1 according to the present embodiment allows the player P to move his / her weight and bring the first edge 14 or the second edge 45 into contact with the sliding surface S (bite in). Is to do.

Here, a case where the player P turns to the right with respect to the traveling direction will be described (in the direction of arrow 62 in FIG. 16).
When the player P moves his / her weight to the front side of the left foot (toe side), the space between the upper plate 6 and the sliding plate 7 on the front side of the left foot (toe side) is compressed as shown in FIG. 57) and the rear side (heel side) of the upper plate 6 and the sliding plate 7 are released (arrow 58), and the sliding play equipment 1 is inclined by γ ° as a whole and the first edge 14a captures the sliding surface S.
At this time, the protrusion 43a of the upper blade 3a is pushed out in the body weight movement direction, so that the second edge 45a bites into the sliding surface S and can be turned more sharply.

That is, when the player P moves his / her weight to the left foot front side (toe side), the space between the left foot front side fixing portion 31 and the left foot front side contact portion 32 is compressed, and as a reaction thereof, the right foot rear side fixing portion 34 and the right foot side The space between the rear contact portions 35 is opened (see FIG. 6). At this time, the left foot front side fixing portion 31 and the right foot rear side fixing portion 34 of the upper layer blade 3 a are fixed to the lower surface of the upper plate 6, but the left foot front side contact portion 32 and the right foot rear side contact portion 35 are fixed to the sliding plate 7. Since the player 43 is only in contact with the upper surface of the player P, the protrusion 43a slides as the player P moves in weight.
Then, as shown in FIG. 15, when the space between the left foot front side fixing portion 31 and the left foot front side contact portion 32 (see FIG. 6) of the upper layer blade 3a is compressed, the upper layer blade 3a is provided in the rubbed portion La. It rotates in the direction of arrow 60 due to the twist. Since the upper layer blade 3a is fixed at both ends by the left foot front side fixing portion 31 and the right foot rear side fixing portion 34, the protruding portion 43a slides on the upper surface of the sliding board 7 and is pushed out in the weight moving direction (arrow 61). . Thereby, as shown to (a) of FIG. 14, the 2nd edge 45a with which the protrusion part 43a was equipped bites into the sliding surface S. As shown in FIG.

  At this time, the upper layer blade 3a, the lower layer blade 3b, and the ball bearings 5 and 5 in the central portion C slide toward the rear side (heel side). That is, in the stationary state, as shown in FIG. 9, the centers of the upper layer blade 3a, the lower layer blade 3b, and the ball bearings 5 and 5 substantially overlap with the center portion C. However, when the player P moves his / her weight to the front side (toe side) of the left foot, the upper layer blade 3a, the lower layer blade 3b, and the ball bearings 5 and 5 slide to the right side in FIG.

  Further, as shown in FIG. 16, when the weight is moved to the front side of the left foot (toe side), a load is also applied to the toe side of the right foot, so the space between the right foot front side fixing portion 40 and the right foot front side contact portion 41 is compressed. (Arrow 59). Since the weight of the player P rests on the left foot front side, the space between the left foot front side fixing portion 31 and the left foot front side contact portion 32 is compressed rather than between the right foot front side fixing portion 40 and the right foot front side contact portion 41. . The protrusion 43d slides with the movement of the player P and is pushed toward the sliding surface S by the substantially same action as the above 43a, so that the second edge 45d bites into the sliding surface S (arrow 63). ).

As a result, the second edge 45a disposed on the projecting portion 43a, the first edge 14a disposed on the sliding plate 7 and the second edge 45d disposed on the projecting portion 43d catch the sliding surface. Further, since the protrusions 43a and 43d having the second edges 45a and 45d are provided with a second side curve r (see FIG. 7) having a radius smaller than the first side curve R of the sliding surface 7, the player P can make a sharper turn.
Further, since the protrusions 43a and 43d are pushed out in the direction of the sliding surface S along with the weight shift, the second edges 45a and 45d are not repelled by the impact of the sliding surface S during the turn, so that the sliding surface Can continue to contact S.
Further, when the player P moves his weight to the front side (toe side) of the right foot while applying a turn in the direction of the arrow 62 (when a large load is applied), the edge 45d disposed on the projecting portion 43d is moved to the sliding surface. In order to further penetrate into S, a sharp turn can be made and braking can be performed.

If it is desired to turn in the opposite direction, as shown in FIG. 14 (b), the weight can be moved to the rear side of the left foot (the heel side of the left foot) and turned.
Further, the same operation can be performed even when the weight is moved to the right foot front side (toe side) and the right foot rear side (heel side).

  Further, since the player P can use the first edge 14 or the second edge 45 properly by changing the weight of the player P, the player P can make a variety of turns.

  When the player P moves his / her weight to the front side of the left foot (toe side of the left foot), the space between the front upper plate 6 and the sliding plate 7 is compressed (arrow 57) as shown in FIG. 14 (a). At the same time, the rear (heel side) upper plate 6 and the sliding plate 7 are opened (arrow 58). At this time, as shown in FIG. 6, the blade 3 is arranged in a substantially X shape in plan view, so that the space between the left foot front side fixing portion 31 and the left foot front side contact portion 32 is compressed, and the reaction thereof is The space between the right foot rear side fixing portion 34 and the right foot rear side contact portion 35 is opened, and weight movement can be smoothly performed in the oblique direction of the longitudinal axis.

  According to the sliding play equipment 1 according to the present embodiment, the main body 2 is formed in a substantially cylindrical shape, and the sliding plate 7 and the upper plate 6 positioned above the sliding plate 7 are connected by the nose plate 8 and the tail plate 9. By doing so, the nose plate 8 and the tail plate 9 serve as cushions, so that the impact received on the foot of the player P can be reduced. Further, since the impact received on the foot of the player P is alleviated, it is possible to obtain a sliding feeling and feel different from those of the conventional art.

  Moreover, since the 1st side curve R is formed in the outer side edge part 13 of the sliding board 7, since the 1st edge 14 catches the sliding surface S along this 1st side curve R, the sliding game equipment 1 is smooth. You can make a turn.

  Further, the blade 3 has a protruding portion 43 having a second edge 45 positioned further outward than the first edge 14 provided at the outer end portion 13 of the sliding plate 7. When the player P moves the weight of the blade 3, the blade 3 slides in the weight moving direction, and the second edge 45 disposed on the protruding portion 43 captures the sliding surface S. Since the second side curve r having a larger curvature than the first side curve R of the sliding plate 7 is disposed at the outer end 44 of the protrusion 43, a sharper turn can be performed.

  In addition, since the sliding play equipment 1 is provided with two blades 3a and 3b obliquely with respect to the longitudinal axis X of the sliding board 7 so as to exhibit an X shape in plan view, for example, on the front side of the left foot (toe side). When the body weight is applied, the space between the left foot front side fixing portion 31 and the left foot front side contact portion 32 is compressed, and as a reaction, the space between the right foot rear side fixing portion 34 and the right foot rear side contact portion 35 is opened. The weight can be moved smoothly. Further, since the blade 3 also has a curved portion, the cushioning property can be further enhanced.

  Moreover, since the sliding game machine 1 has the ball bearing 5, it can reduce the friction which arises in the sliding board 7 and the blade 3 which contact, and can make the blade 3 slide smoothly.

  Further, the sliding play equipment 1 has the cushioning property between the upper plate 6 and the sliding plate 7 by interposing the spring 4 between the upper plate 6 and the sliding plate 7. It is possible to flexibly cope with the vertical load received.

  Further, since the width of the sliding plate 7 is narrower than the width of the upper plate 6, the frictional resistance with the sliding surface 7 is reduced, the sliding speed is increased, and the movable range of the weight movement is reduced, so that the turn can be easily performed. It can be carried out.

  As mentioned above, although embodiment concerning this invention was described in detail with reference to drawings, this invention is not limited to this, In the range which does not deviate from the meaning of this invention, it can change suitably.

The leg portion 76 (76a to 76d) extends from the central portion W so as to exhibit a substantially X shape in plan view.

The blade 73 has curved portions 78 (78a to 78d) formed by curving the foot portion 76, and the distal end portions 77 (77a to 77d) of the foot portion 76 are fixed to the lower surface of the upper plate 79. . As shown in FIG. 17B, the blade 73 is provided with a protruding portion 85 (85 a to 85 d) that protrudes outward from the outer end portion 83 (dotted line portion) of the sliding plate 82. Further, the outer end 86 (86a to 86d) of the protrusion 85 has a second side curve r having a radius smaller than the radius of the first side curve R provided on the outer end 83 of the sliding plate 82. . In addition, second edges 84 (84a to 84d) are provided at outer end portions 86 (86a to 86d) of the protruding portion 85.
As shown in FIG. 18A, the foot portion 76b and the foot portion 76d of the blade 73 in the KK cross section of FIG. 17B are formed in a substantially mountain shape. Further, as shown in FIG. 18B, the foot portion 76b and the foot portion 76d are horizontal at a portion where the foot portions 76b and 76d are in contact with the upper surface of the sliding plate 82.
Note that the manufacturing method and operation are substantially the same as those in the first embodiment, and thus are omitted.

  According to the second embodiment, the foot 73 extends from the central portion W so that the blade 73 has an X shape in plan view. That is, since the blade 73 is formed from a single plate, there is no height between the blades unlike the upper layer blade 3a and the lower layer blade 3b of the first embodiment. Therefore, the operation | work which rubs the leg parts 76a-76d of the braid | blade 73 equally becomes easy.

<Third embodiment>
In the first embodiment and the second embodiment, the foot of the player P is fixed so as to be substantially perpendicular to the longitudinal direction of the sliding playground equipment 1, 71, but the present invention is not limited to this. For example, as shown in FIG. 19, one foot of the player P may be fixed to each of the sliding playground equipment 90, 90. At that time, the toes of the player P are fixed so as to be parallel to the longitudinal direction of the sliding play equipment 1.
In this embodiment, the sliding play equipment 90 includes a main body 93 having an upper plate 91 and a sliding plate 92, a blade 94, a spring 95, and a bearing (not shown). The width of the upper plate 91 and the sliding plate 92 is slightly wider than the width of the player P's foot. The length of the sliding play equipment 90 in the longitudinal direction is shorter than that of the above-described sliding play equipment 1 and is about 100 cm. The foot of the player P is fixed substantially above the spring 95.

A box-like body or the like suitable for placing the vehicle may be installed and used in substantially the same form as the sled. Such a case will be described with reference to FIG. 16. When a player rides on a box-like body (not shown) installed on the upper plate 6 and moves his / her weight, the operation is substantially the same as in this embodiment. The sliding play equipment 1 can be operated.

  Further, an object (including a person) may be placed on the box-like body and pulled from the nose plate 8 side (see FIG. 1). For example, when towing from the arrow 62 side in FIG. 16, the load of the object placed on the box-like body acts on the blade 3 according to the towing direction or the change of the sliding surface S. Thereby, since the blade 3 slides and the second edge 45a in the pulling direction captures the sliding surface S, the sliding play equipment 1 can smoothly follow the pulling direction. Moreover, since the sliding playground equipment 1 is provided with the protrusion part 43, it can prevent the fall by sudden operation.

  Moreover, the sliding playground equipment according to the present invention may be configured by only the main body 2 (see FIG. 2B), for example. Thereby, since the sliding playground equipment becomes light by reducing the members constituting the sliding playground equipment as much as possible, it is possible to adapt to air-based games.

  The present invention relates to a sliding play equipment that slides on a snow surface, a turf surface or the like.

An example of a sliding playground equipment that slides on a slope by the player's own weight is a snowboard that slides on a snow surface. Conventionally used snowboards are composed of a single plate formed in an oval shape in plan view, and the lower surface of the plate is used as a sliding surface and the upper surface is used as a boarding surface on which a player rides. The player can make left and right turns by transmitting weight shift to the board.
JP 2004-160095 A

However, since most snowboards are made of a single plate and have a substantially oval shape in plan view, the feeling that the player receives from the snow surface, the sliding comfort, etc., are not much different. In addition, since only one board is interposed between the snow surface and the player's foot, the impact on the player's foot from the snow surface was very large.

As a result, the player can obtain a different sliding feeling than before. Further, since the blades are arranged so as to have a substantially X shape in a plan view, the player can move the weight smoothly.

Moreover, it is preferable that the lower layer blade and the upper layer blade respectively have a pair of projecting portions formed to project outward from the outer end portion of the sliding plate at the contact portion .

According to this structure, since the protrusion part of a braid | blade protrudes outside rather than the outer side edge part of a sliding board, a protrusion part can be made to contact a sliding surface by a player's weight shift. Thereby, the turn can be guided not only by the sliding plate but also by the blade.

Moreover, it is preferable that the bearing is interposed in the position where the said sliding board and the said lower layer blade cross | intersect.

According to such a configuration, it is possible to smoothly slide the portion where the sliding plate and the lower layer blade intersect .

Moreover, it is preferable that a bearing is interposed at a position where the lower layer blade and the upper layer blade intersect.

According to such a configuration, it is possible to smoothly slide the portion where the lower layer blade and the upper layer blade intersect.

Moreover, it is preferable that the width | variety of the said sliding board is narrower than the width | variety of the said upper board. According to this configuration, the frictional resistance between the sliding plate and the sliding surface is reduced, the sliding speed can be increased, and the range in which the body weight is transmitted is reduced, so that the turn can be easily performed.

Moreover, it is preferable that the radius of the side curve formed in the outer side edge part of the said protrusion part is smaller than the radius of the side curve formed in the outer side edge part of the said sliding board.

According to such a configuration, the outer end of the sliding plate or the outer end of the protruding portion can be brought into contact with the sliding surface by moving the weight of the player, so that a variety of turns can be performed.

Moreover, it is preferable that an elastic body is interposed between the upper layer blade and the upper plate. According to such a configuration, the cushioning property is further improved, so that it is possible to further absorb the impact received on the player's foot from the running surface.

Further, the present invention is interposed between a sliding plate that contacts the sliding surface and an upper plate located above the sliding plate, and the lower blade and the upper blade are crossed at the center of the sliding plate. The lower layer blade and the upper layer blade are formed by curving both ends of the plate-like member, and the upper end blade is formed at the one end side and the other end side. A pair of fixing portions fixed to the plate, a pair of contact portions that contact the sliding plate on the one end side and the other end side, and the fixing portion and the contact portion are connected, and the one end side and the other end are connected. And a pair of curved portions that are curved on the side.

According to such a configuration, since the curved portion formed on the blade serves as a cushion, it is possible to absorb an impact received on the player's foot from the running surface. Further, since the blades are arranged so as to have a substantially X shape in a plan view, the player can move the weight smoothly.

The manufacturing method described above is merely an example and does not limit the present invention.

<Operation status>
Next, the operation state of the sliding playground equipment 1 will be described. In the description of the present embodiment, a case of sliding on a snow surface (piste) will be described.
As shown in FIG. 1, the sliding play equipment 1 fixes the foot of the player P to the foot fixing devices T and T fixed to the upper plate 6, and slides by its own weight when facing the slope (sliding surface). It is a surface that slides. In the present embodiment, it is assumed that the left foot faces the traveling direction of the sliding surface.
In the description of the present embodiment, the compression means that the upper plate 6 and the sliding plate are moved when the player P moves the weight when the weight of the player P acts perpendicularly to the sliding plate 7. 7 distance (distance between the adhering portion and the contact portion) is shorter than the stationary state. Moreover, opening means that the distance (distance of a adhering part and a contact part) of the upper board 6 and the sliding board 7 becomes longer than a stationary state.

(When sliding straight)
As shown in FIG. 12, the player P can slide straight by causing the weight of the player P to act vertically on the sliding board 7. That is, when the weight of the player P acts perpendicularly to the sliding board 7, the second edges 45 a and 45 c disposed on the blade 3 do not come into contact with the sliding surface S. The entire surface can touch the running surface and slide straight.
As shown in FIG. 13, when the player P moves his / her weight to the left foot along the traveling direction, the space between the upper plate 6 on the left foot side and the sliding plate 7 is compressed (arrow 55) and the blade 3 Due to the reaction, the space between the upper plate 6 on the right foot side and the sliding plate 7 is opened (arrow 56), so that the weight can be moved smoothly.

(When making a turn)
As shown in FIG. 14, the sliding play equipment 1 according to the present embodiment allows the player P to move his / her weight and bring the first edge 14 or the second edge 45 into contact with the sliding surface S (bite in). Is to do.

Here, a case where the player P turns to the right with respect to the traveling direction will be described (in the direction of arrow 62 in FIG. 16).
When the player P moves his / her weight to the front side of the left foot (toe side), the space between the upper plate 6 and the sliding plate 7 on the front side of the left foot (toe side) is compressed as shown in FIG. 57) and the rear side (heel side) of the upper plate 6 and the sliding plate 7 are released (arrow 58), and the sliding play equipment 1 is inclined by γ ° as a whole and the first edge 14a captures the sliding surface S.
At this time, the protrusion 43a of the upper blade 3a is pushed out in the body weight movement direction, so that the second edge 45a bites into the sliding surface S and can be turned more sharply.

That is, when the player P moves his / her weight to the left foot front side (toe side), the space between the left foot front side fixing portion 31 and the left foot front side contact portion 32 is compressed, and as a reaction thereof, the right foot rear side fixing portion 34 and the right foot side The space between the rear contact portions 35 is opened (see FIG. 6). At this time, the left foot front side fixing portion 31 and the right foot rear side fixing portion 34 of the upper layer blade 3 a are fixed to the lower surface of the upper plate 6, but the left foot front side contact portion 32 and the right foot rear side contact portion 35 are fixed to the sliding plate 7. Since the player 43 is only in contact with the upper surface of the player P, the protrusion 43a slides as the player P moves in weight.
Then, as shown in FIG. 15, when the space between the left foot front side fixing portion 31 and the left foot front side contact portion 32 (see FIG. 6) of the upper layer blade 3a is compressed, the upper layer blade 3a is provided in the rubbed portion La. It rotates in the direction of arrow 60 due to the twist. Since the upper layer blade 3a is fixed at both ends by the left foot front side fixing portion 31 and the right foot rear side fixing portion 34, the protruding portion 43a slides on the upper surface of the sliding board 7 and is pushed out in the weight moving direction (arrow 61). . Thereby, as shown to (a) of FIG. 14, the 2nd edge 45a with which the protrusion part 43a was equipped bites into the sliding surface S. As shown in FIG.

At this time, the upper layer blade 3a, the lower layer blade 3b, and the ball bearings 5 and 5 in the central portion C slide toward the rear side (heel side). That is, in the stationary state, as shown in FIG. 9, the centers of the upper layer blade 3a, the lower layer blade 3b, and the ball bearings 5 and 5 substantially overlap with the center portion C. However, the player P is by moving the body weight left foot front side (toe side), the upper layer blade 3a, the lower layer blade 3b and the ball bearings 5, 5 slides to the left side toward the paper surface of FIG.

Further, as shown in FIG. 16, when the weight is moved to the front side of the left foot (toe side), a load is also applied to the toe side of the right foot, so the space between the right foot front side fixing portion 40 and the right foot front side contact portion 41 is compressed. (Arrow 59). Since the weight of the player P rests on the left foot front side, the space between the left foot front side fixing portion 31 and the left foot front side contact portion 32 is compressed rather than between the right foot front side fixing portion 40 and the right foot front side contact portion 41. . The protrusion 43d slides with the movement of the player P and is pushed out toward the sliding surface S by the substantially same action as the above-described protrusion 43a, so that the second edge 45d bites into the sliding surface S ( Arrow 63).

As a result, the second edge 45a disposed on the projecting portion 43a, the first edge 14a disposed on the sliding plate 7 and the second edge 45d disposed on the projecting portion 43d catch the sliding surface. Further, since the protrusions 43a and 43d having the second edges 45a and 45d are provided with a second side curve r (see FIG. 7) having a radius smaller than the first side curve R of the sliding plate 7, the player P can make a sharper turn.
Further, since the protrusions 43a and 43d are pushed out in the direction of the sliding surface S along with the weight shift, the second edges 45a and 45d are not repelled by the impact of the sliding surface S during the turn, so that the sliding surface Can continue to contact S.
Further, when the player P moves in the direction of the arrow 62 and moves his / her weight to the front side (toe side) of the right foot (when a large load is applied), the second edge 45d disposed on the protruding portion 43d is moved. Since it further bites into the sliding surface S, a sharp turn can be made and braking can be performed.

If it is desired to turn in the opposite direction, as shown in FIG. 14 (b), the weight can be moved to the rear side of the left foot (the heel side of the left foot) and turned.
Further, the same operation can be performed even when the weight is moved to the right foot front side (toe side) and the right foot rear side (heel side).

Further, the player P is the movement acceleration of the weight of the player P, it is possible to selectively use the first edge 14 or second edge 45, it is possible to perform a turn rich Baraete I.

  When the player P moves his / her weight to the front side of the left foot (toe side of the left foot), the space between the front upper plate 6 and the sliding plate 7 is compressed (arrow 57) as shown in FIG. 14 (a). At the same time, the rear (heel side) upper plate 6 and the sliding plate 7 are opened (arrow 58). At this time, as shown in FIG. 6, the blade 3 is arranged in a substantially X shape in plan view, so that the space between the left foot front side fixing portion 31 and the left foot front side contact portion 32 is compressed, and the reaction thereof is The space between the right foot rear side fixing portion 34 and the right foot rear side contact portion 35 is opened, and weight movement can be smoothly performed in the oblique direction of the longitudinal axis.

  According to the sliding play equipment 1 according to the present embodiment, the main body 2 is formed in a substantially cylindrical shape, and the sliding plate 7 and the upper plate 6 positioned above the sliding plate 7 are connected by the nose plate 8 and the tail plate 9. By doing so, the nose plate 8 and the tail plate 9 serve as cushions, so that the impact received on the foot of the player P can be reduced. Further, since the impact received on the foot of the player P is alleviated, it is possible to obtain a sliding feeling and feel different from those of the conventional art.

  Moreover, since the 1st side curve R is formed in the outer side edge part 13 of the sliding board 7, since the 1st edge 14 catches the sliding surface S along this 1st side curve R, the sliding game equipment 1 is smooth. You can make a turn.

  Further, the blade 3 has a protruding portion 43 having a second edge 45 positioned further outward than the first edge 14 provided at the outer end portion 13 of the sliding plate 7. When the player P moves the weight of the blade 3, the blade 3 slides in the weight moving direction, and the second edge 45 disposed on the protruding portion 43 captures the sliding surface S. Since the second side curve r having a larger curvature than the first side curve R of the sliding plate 7 is disposed at the outer end 44 of the protrusion 43, a sharper turn can be performed.

In addition, the sliding play equipment 1 is provided with two upper layer blades 3a and lower layer blades 3b obliquely with respect to the longitudinal axis X of the sliding plate 7 so as to have an X shape in plan view. When the weight is applied to the side), the space between the left foot front side fixing portion 31 and the left foot front side contact portion 32 is compressed, and at the same time, the reaction between the right foot rear side fixing portion 34 and the right foot rear side contact portion 35 is opened. The player P can move the weight smoothly. Further, since the blade 3 also has a curved portion, the cushioning property can be further enhanced.

  Moreover, since the sliding game machine 1 has the ball bearing 5, it can reduce the friction which arises in the sliding board 7 and the blade 3 which contact, and can make the blade 3 slide smoothly.

  Further, the sliding play equipment 1 has the cushioning property between the upper plate 6 and the sliding plate 7 by interposing the spring 4 between the upper plate 6 and the sliding plate 7. It is possible to flexibly cope with the vertical load received.

Further, since the width of the sliding board 7 is narrower than the width of the upper board 6, the frictional resistance with the sliding surface S is reduced, the sliding speed is increased, and the movable range of the weight movement is reduced, so that the turn can be easily performed. It can be carried out.

  As mentioned above, although embodiment concerning this invention was described in detail with reference to drawings, this invention is not limited to this, In the range which does not deviate from the meaning of this invention, it can change suitably.
