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 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 an 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 is a projecting portion that projects outward from the outer end portion of the sliding plate, and a second side curve 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 provided with 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, the blade refers to a plate that is interposed between the sliding plate and the upper plate and serves as a cushion that absorbs an impact and guides the turn by contacting the sliding surface.

  The present invention also 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 in contact with the upper surface of the sliding plate. And a curved portion provided on the nose plate side and the tail 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.

  In the present invention, a support portion that reduces friction between the sliding plate, the blade, and the blade may be provided at a location where the sliding plate intersects with the blade and the blade.

  According to this invention, since the friction which arises when a sliding board, a braid | blade, and braid | blades contact can be reduced, a braid | 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.

  In the present invention, the width of the sliding surface may be narrower than the width of the riding surface.

  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.

  Moreover, you may form the recessed part which became depressed toward the sliding board in the upper board in this invention.

  According to this invention, since the height position of the player's foot can be lowered, it is easy to get on and off the sliding playground equipment. In addition, since the distance from the player's foot to the sliding board is shortened, it becomes easier to transmit the player's weight shift to the sliding board, and it is possible to slide more smoothly.

  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 located above the sliding plate, A contact portion that is in contact with the upper surface of the sliding plate, a curved portion provided at both ends of the contact portion, and a fixing portion that fixes the both ends of the blade to the lower surface of the upper plate, than the outer end portion of the sliding plate. A protruding portion that protrudes outward is 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.

Next, the operation state of the sliding playground equipment 1 will be described. In addition, in description of 1st embodiment, the case where it slides on a snow surface (piste) is demonstrated.
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 first embodiment, it is assumed that the left foot faces the traveling direction of the running surface.
In the description of the first embodiment, the compression means that the upper plate 6 moves when the player P moves his / her weight when the weight of the player P is acting perpendicularly to the sliding plate 7. And the distance between the sliding plate 7 (the distance between the fixed portion and the contact portion) is shorter than that in 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 first embodiment moves the weight of the player P and causes the first edge 14 or the second edge 45 to come into contact with the sliding surface S. It is what makes a turn.

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 playground equipment 1 has an angle 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 support portions 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 support portions 5 and 5 substantially overlap the center portion C. However, when the player P moves the weight to the front side of the left foot (toe side), the upper layer blade 3a, the lower layer blade 3b, and the support portions 5 and 5 slide so as to be pushed out to the heel side.

  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). ).

From the above, the second edge 45a disposed on the protrusion 43a, the first edge 14a disposed on the sliding plate 7, and the second edge 45d disposed on the protrusion 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 as the player P moves in weight, the second edges 45a and 45d are not repelled by the impact of the sliding surface S during the turn. , Can continue to contact the sliding surface 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 first 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 connecting, 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 support part 5, the friction which arises in the sliding board 7 and the braid | blade 3 which touches can be reduced, and the braid | blade 3 can be slid 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.

  Moreover, since the width of the sliding board 7 is narrower than the width of the upper board 6, the frictional resistance with the sliding board 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.

<Fourth embodiment>
As shown in FIG. 20, the sliding play equipment 110 according to the fourth embodiment is different from the other embodiments in the structure of the upper plate 116 and the structure of the support portion 130.
As shown in FIGS. 20A and 20C, the upper plate 116 according to the sliding play apparatus 110 is formed with recesses 120 and 120 spaced from the central portion C at substantially equal intervals. As shown in FIG. 20C, the recess 120 is formed by recessing a part of the upper plate 116 toward the sliding plate 117 side. The bottom surface of the recess 120 is formed flat, and the foot of the player P is fixed via the foot fixing tool T.

  By providing the recess 120 in the upper plate 116 in this way, the height position of the player P's foot can be lowered, so that it is easy to get on and off the sliding play equipment 110. In addition, since the distance from the foot of the player P to the sliding board 117 is shortened, it becomes easier to transmit the weight movement of the player P to the sliding board 117, and it is possible to slide more smoothly. Note that, in the central portion C of the upper plate 116, as shown in FIG. 20B, both ends of the upper plate 116 may be curved downward.

  In the fourth embodiment, as shown in FIG. 20C, the height of the upper plate 116 in the central portion C is higher than the bottom surface of the recess 120, but is not limited thereto. It is not something. For example, one concave portion 120 may be formed, and the center portion C and the bottom surface of the concave portion 120 may be formed at the same position. The shape of the recess 120 may be other shapes.

As shown in FIG. 20B and FIG. 21A, the support portion 130 according to the fourth embodiment penetrates through a through hole 131 formed in the lower layer blade 113b, and includes the sliding plate 117 and the upper layer blade. It is installed between 113a.
The support unit 130 includes a rotating body 132 installed in contact with the top and bottom, a rotating shaft 133 inserted through the rotating body 132, a T-shaped metal fitting 134 through which the rotating shaft 133 is inserted, a T-shaped metal fitting 134, and a lower blade. 113b which joins 113b.

  The rotating body 132 includes a first rotating body 132a positioned below and a second rotating body 132b positioned above, and is a hard rubber sphere having the same diameter. The first rotating body 132a has a lower end in contact with the sliding plate 117 and an upper end in contact with the second rotating body 132b. The second rotating body 132b has a lower end in contact with the first rotating body 132a and an upper end in contact with the upper layer blade 113a.

  The rotating shaft 133 includes a first rotating shaft 133a and a second rotating shaft 133b that are inserted through the centers of the first rotating body 132a and the second rotating body 132b, respectively. The axial directions of the first rotating shaft 133a and the second rotating shaft 133b are parallel to the longitudinal direction of the sliding play apparatus 110 and are formed horizontally. Both ends of the rotating shaft 133 are formed with thread grooves, and are fastened with nuts 133c.

  The T-shaped bracket 134 includes a pair of a first T-shaped bracket 134a and a second T-shaped bracket 134b. The T-shaped bracket 134 pivotally supports the rotating body 132 and is joined to the lower blade 113b via the joining portion 135. As shown in FIG. 22, the T-shaped metal fitting 134 includes a substrate portion 137 in which long holes 136 and 136 are formed, and an overhang portion 138 formed perpendicularly from the substrate portion 137. The long hole 136 has an oblong shape in cross section extending up and down, and is formed in the substrate portion 137 at two locations. The long hole 136 is inserted through the rotation shaft 133, and the rotation shaft 133 is formed to be movable up and down within the long hole 136. That is, the shaft diameter of the rotating shaft 133 is formed smaller than the hole width of the long hole 136, and the nuts 133 c installed at both ends of the rotating shaft 133 are fastened at positions separated from the substrate portion 137. . The overhanging portion 138 extends in parallel to the longitudinal direction of the sliding play equipment 110 and is joined to the lower blade 113b by the joining portion 135.

  As shown in FIG. 22, the joining portion 135 is a portion that joins the T-shaped metal fitting 134 and the lower layer blade 113b. In the joint portion 135, the absorbent material 140 is inserted into a communication hole that communicates with the overhang portion 138 and the lower blade 113 b, and is fastened with a bolt 142 and a nut 143 through a washer 141. The absorbent material 140 has a cylindrical shape having a hollow portion through which the bolt 142 is inserted, and has a central portion constricted inward. That is, both end sides of the absorbent material 140 are formed thicker than the central portion. As the absorbent material 140, for example, a known rubber bush is used. By using the absorbent material 140, the load acting on the support portion 130 is absorbed and the movement in the longitudinal direction is allowed. Moreover, since the both ends of the absorber 140 are formed thicker than the center part, it can respond flexibly with respect to the load which acts.

  According to the support portion 130, when the player P moves the body weight in the front-rear direction (toe side or heel side), the first rotating body 132a and the second rotating body 132b rotate while rotating around the rotating shaft 133. Therefore, the upper layer blade 113a and the lower layer blade 113b slide smoothly in the width direction. Further, since the absorbing material 140 is inserted, the load acting on the support portion 130 is absorbed, and the upper layer blade 113a and the lower layer blade 113b are allowed to move in the longitudinal direction. As a result, the second edge of the upper layer blade 113a and the lower layer blade 113b can be bitten into the sliding surface by moving the weight of the player P in the same manner as the sliding play equipment 1 according to the first embodiment, so that the turn is sharp. be able to.

  Here, if the rotating shaft 133 is fixed to the T-shaped metal fitting 134, the first rotating body 132a and the second rotating body 132b are worn, and a gap is formed between them, which may cause idling. is there. However, in the fourth embodiment, since the long hole 136 is formed, the rotating shaft 133 moves up and down in the long hole 136. Thereby, when the load of the player P acts on the upper plate 116, the first rotating body 132a and the second rotating body 132b are always in contact with each other, so that idling can be prevented.

  In addition, in 4th embodiment, although the above-mentioned support part 130 was used, another form may be sufficient. For example, the rotating body 132 is a sphere, but may be an elliptical sphere, for example. In addition, although the pair of metal fittings 134 is a pair of metal fittings, they may be integrally formed. Further, the shape and material of the absorbent material 140 may be appropriately set according to the play style of the player P. Further, in order to prevent wear between the long hole 136 and the rotating shaft 133, a cushioning material may be provided along the shape inside the long hole 136.

The embodiment according to the present invention has been described above. However, the present invention is not limited to this, and can be appropriately changed without departing from the spirit of the present invention. Moreover, the usage may be used not only for games but also for other usages.
In the first embodiment and the second embodiment, the sliding playground equipment 1 is used in substantially the same form as the snowboard. For example, an object or a person is placed on the upper plate 6 of the sliding playground equipment 1. A suitable box-like body may be installed and used in 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 the first 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.

  In addition, the sliding playground equipment according to the present invention may be configured by only the main body 2 without using the blade 3, the spring 4, and the support 5 (see FIG. 2B). 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.

  Further, in the description of the first embodiment, the sliding playground equipment according to the present invention has been described on the case of sliding on the snow surface, but is not limited to this, for example, turf surface, sand surface or water surface. Can also glide.

  In the description of the first embodiment, the blade 3 is used in the sliding play equipment 1, but the blade 3 is not limited to this and can be provided in another structure.
