Gliding playground equipment and blade

Technical field

[0001] The present invention relates to a sliding playground equipment that slides on a snow surface, a turf surface or the like.

Background art

[0002] As a sliding playground equipment that slides on a slope by the player's own weight, a snowboard that slides on a snow surface can be mentioned. Conventionally used snowboards consist of a single plate formed in a substantially 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 a left or right turn by transmitting weight shift to the board (see Japanese Patent Laid-Open No. 2004-160095).

Disclosure of the invention

Problems to be solved by the invention

[0003] However, since most snowboards also have a single plate strength and have a substantially oval shape in plan view, the feeling that the player receives on the snow surface, the feeling of sliding, etc. are not much different. It was. Also, since there was only one board between the snow surface and the player's foot, the impact on the snow surface player's foot was very large.

The present invention has been made to solve the problem of power, and is a play equipment that slides on slopes such as turf, sand, etc., not only on the snow surface, and reduces the physical burden on the player. At the same time, it is an object of the present invention to provide a sliding playground equipment capable of obtaining a sliding feeling different from that of a conventional sliding playground equipment and a blade suitable for mitigating impact.

Means for solving the problem

[0004] 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.

[0005] According to such an invention, the nose plate and the tail plate are used as the cushion because the nose plate and the tail plate are connected to the upper plate located above the planing plate, which is formed in a substantially cylindrical shape. It can alleviate the impact on the player's feet. Also By mitigating the impact on the player's foot, it is possible to obtain a different sliding feeling and insect sensation than before.

[0006] Further, the present invention may have a first side curve at the outer end.

[0007] According to the powerful invention, the first side curve is formed at the outer end portion of the sliding plate, so that the first edge having the curve catches the running surface smoothly. You can make turns.

[0008] In addition, the present invention is a second projecting portion projecting outward from the outer end portion of the sliding plate and a second projecting portion formed on the outer end portion of the projecting portion and having a curvature force larger than the curvature of the first side curve. A blade having a side 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 board.

[0009] According to the powerful invention, the blade has a protrusion having a second edge positioned further outward than the first edge provided at the outer end of the sliding plate. Since the blade is in contact with the upper surface of the sliding board, when the player moves the 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 force than the first side curve of the sliding plate is disposed at the outer end portion of the protruding portion, a sharper turn can be performed. The first edge or the second edge can be used properly depending on the movement of the player's weight, making it possible to make a turn rich in nature.

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 impact, and also guides the turn by contacting the sliding surface.

[0010] 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 nose plate side and the tail plate side, and a fixing portion fixed to the lower surface of the upper plate.

[0011] 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 blade forces having 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 foot toe side to the right foot heel side. Also 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 In other words, the player's weight can be moved smoothly by the elasticity of the blade.

In addition, since the curved part of the blade acts as a cushion, the impact received by the player's feet can be further mitigated.

[0012] 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, the blade, and the blade intersect each other.

[0013] According to the powerful invention, it is possible to reduce friction generated when the sliding plate, the blade, and the blades come into contact with each other, so that the blade can be smoothly slid.

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

[0015] According to the powerful invention, by providing an elastic body between the sliding plate and the upper plate, the cushioning properties of the sliding plate and the upper plate are enhanced. It can respond flexibly.

[0016] In the present invention, the width of the sliding surface may be narrower than the width of the riding surface.

[0017] According to the powerful invention, the frictional resistance with 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.

[0018] In the present invention, the upper plate may be formed with a recessed portion that is recessed toward the sliding plate.

[0019] According to the powerful invention, the height position of the player's foot can be lowered, so it is easy to get on and off the sliding play 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.

[0020] 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 between the sliding plate and the upper plate positioned 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 both ends of the blade to the lower surface of the upper plate, and is provided on the outer side of the sliding plate. From the end Is also provided with a protruding portion protruding outward.

[0021] According to the powerful invention, the blade is interposed with the curved portion between the sliding plate and the upper plate, so that the impact applied to the sliding plate and the upper plate can be reduced.

[0022] According to the present invention, in a sliding playground equipment that slides not only on the snow surface but also on the turf surface, sand surface, etc., the burden on the player's foot is alleviated and slipping different from conventional sliding playground equipment is possible. Can get the ground.

[0054] <Operation status>

Next, the operation state of the sliding playground equipment 1 will be described. For the explanation of the first embodiment! I will explain how to ski on the snow! As shown in Fig. 1, the sliding play equipment 1 has the foot fixing tool 上方, T fixed to the upper plate 6, and the player's P foot is fixed to T, and the player's own weight is applied to the slope (sliding surface). It slides on the running surface. 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 player P moves the weight when the weight of the player P is acting perpendicularly to the sliding board 7, and the player P moves the weight. This means that the distance between 6 and the sliding plate 7 (the distance between the fixed part and the contact part) is shorter than in the stationary state. The term “open” means that the distance between the upper plate 6 and the sliding plate 7 (the distance between the fixed portion and the contact portion) is longer than that in the stationary state.

[0055] (When sliding straight)

As shown in FIG. 12, the player P can slide straight by causing the weight of the player P to act perpendicularly to 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 contact the sliding surface S. The entire surface can come into contact with the sliding surface and slide straight.

As shown in FIG. 13, when the player P moves the weight to the left foot along the direction of travel, 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.

[0056] (When making a turn)

As shown in FIG. 14, in the sliding play equipment 1 according to the first embodiment, the player P moves his / her weight, and the first edge 14 or the second edge 45 is brought into contact with the sliding surface S (bite in). , To make turns.

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), as shown in FIG. 14 (a), the space between the upper plate 6 and the sliding plate 7 on the front side of the left foot (toe side) is compressed (arrow 5 7), the rear side (heel side) of the upper plate 6 and the sliding plate 7 is released (arrow 58), and the sliding game Tool 1 as a whole has an angle γ tilt first edge 14a catches the sliding surface S.

At this time, since the protrusion 43a of the upper layer blade 3a is pushed out in the body weight movement direction, the second edge 45a bites into the sliding surface S, and a more sharp turn can be made.

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 sticking is performed. The space between the portion 34 and the right foot rear contact portion 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 3a 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 connected to the sliding plate 7 Since the player 43 only touches the upper surface of the player P, the protrusion 43a slides as the player P moves in weight.

As shown in FIG. 15, when the space between the left foot front side fixing part 31 and the left foot front side contact part 32 (see FIG. 6) of the upper layer blade 3a is compressed, the upper layer blade 3a is provided in the rubbed part La. Rotates in the direction of arrow 60 due to twist. Since the upper blade 3a is fixed at both ends by the left foot front side fixing part 31 and the right foot rear side fixing part 34, the protrusion 43a slides on the upper surface of the sliding board 7 and is pushed out in the direction of weight movement (arrow 61). . Thereby, as shown in FIG. 14 (a), the second edge 45a provided in the protrusion 43a bites into the sliding surface S.

[0059] 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. 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 to the heel side.

[0060] Also, as shown in FIG. 16, when the weight is moved to the front side of the left foot (toe side), the load is also applied to the toe side of the right foot, so the right foot front side fixing portion 40 and the right foot front side contact portion 41 The space is compressed (arrow 59). Since player P's weight is exerted mainly on the left foot front side, the space between the left foot front sticking portion 31 and the left foot front contact portion 32 is compressed rather than between the right foot front sticking portion 40 and the right foot front contact portion 41. . The protrusion 43d slides with the movement of the player P and is pushed out toward the sliding surface S due to substantially the same action as 43a described above, so that the second edge 45d bites into the sliding surface S ( Arrow 63). [0061] As described 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 Capture. In addition, 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 scale of the sliding plate 7. Player P can make a sharper turn.

In addition, since the protrusions 43a and 43d are pushed out in the direction of the sliding surface S as the player P moves, the second edges 45a and 45d are hit by the impact of the sliding surface S during the turn. You can continue to touch the running surface S.

In addition, when player P makes a turn in the direction of arrow 62 and moves his weight to the front side (toe side) of the right foot (when a large load is applied), edge 45 5d arranged on protrusion 43d slides. To further penetrate surface S, you can make a sharp turn and brake.

[0062] 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 left foot heel side).

The same operation can be performed by moving the weight to the front side of the right foot (toe side) and the back side of the right foot (heel side).

[0063] Further, the player P can use either the first edge 14 or the second edge 45 by changing the weight of the player P. Therefore, the player P can make a variety of turns.

[0064] Further, when the weight is moved to the player P force left foot front side (toe side of the left foot), as shown in FIG. 14 (a), the space between the front upper plate 6 and the sliding plate 7 is compressed (arrow At the same time, the rear (heel side) upper plate 6 and sliding plate 7 are opened (arrow 58). At this time, as shown in FIG. 6, since the blade 3 is arranged in an approximately X shape in plan view, 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 In addition, the space between the right foot rear side fixing portion 34 and the right foot rear side contact portion 35 is opened, and the weight shift can be smoothly performed with respect to 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 located above the sliding plate 7 are connected to the nose plate 8 and the tail. Connect with plate 9 Thus, since the nose plate 8 and the tail plate 9 serve as cushions, it is possible to mitigate the impact on the player's foot. In addition, by reducing the impact on player P's feet, it is possible to obtain a different sliding comfort and feel.

[0066] Further, in the sliding playground equipment 1, since the first side curve R is formed at the outer end portion 13 of the sliding board 7, the first edge 14 moves along the first side curve R along the sliding surface S. You can make a smooth turn to catch.

In addition, the blade 3 has a protrusion 43 having a second edge 45 positioned further outward than the first edge 14 provided at the outer end 13 of the sliding plate 7. When the player 1 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 protrusion 43 catches the sliding surface S. Since a 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 made. .

[0068] Further, since 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 weight is applied to the left foot front side (toe side), the space between the left foot front sticking portion 31 and the left foot front touching portion 32 is compressed, and as a reaction, the right foot rear sticking portion 34 and the right foot rear touching portion The space between 35 is open and player P can move weight smoothly. Further, since the blade 3 also has a curved portion, the cushioning property can be further improved.

[0069] Further, since the sliding playground equipment 1 has the support portion 5, the friction generated between the sliding plate 7 and the blade 3 that are in contact with each other can be reduced, and the blade 3 can be smoothly slid.

[0070] In addition, the sliding playground equipment 1 is provided with a spring 4 between the upper plate 6 and the sliding plate 7, so that the cushioning properties of the upper plate 6 and the sliding plate 7 are improved. It can flexibly cope with the vertical load that the plate 7 receives.

[0071] 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 plate 7 is reduced, the sliding speed is increased, and the movable range of weight movement is reduced. You can easily make turns.

The embodiments according to the present invention have been described in detail above with reference to the drawings. However, the present invention is not limited to the embodiments, and may be modified as appropriate without departing from the spirit of the present invention. Is possible.

[0078] <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. 20 (a) and 20 (c), the upper plate 116 of the sliding play apparatus 110 is formed with recesses 120, 120 in which the central portion C force is also spaced at substantially equal intervals. As shown in FIG. 20 (c), 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.

[0079] By providing the recess 120 in the upper plate 116 in this way, the height position of the foot of the player P can be lowered, and thus it is easy to get on and off the sliding play equipment 110. In addition, since the distance to the player's P power sliding board 117 is shortened, it becomes easier to transmit the weight shift of the player P to the sliding board 117, and the player can slide more smoothly. In the central portion C of the upper plate 116, both ends of the upper plate 116 should be curved downward as shown in FIG. 20 (b).

In the fourth embodiment, as shown in FIG. 20 (c), the height of the upper plate 116 in the central portion C is higher than the bottom surface of the recess 120. Limited It is not a thing. 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.

[0081] As shown in Fig. 20 (b) and Fig. 21 (a), the support portion 130 according to the fourth embodiment penetrates through a through hole 131 formed in the lower blade 113b, and the sliding plate Installed between 117 and upper blade 113a!

The support 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 bracket 134 through which the rotating shaft 133 is inserted, a T-shaped bracket 134, and a lower layer bracket. And a joint portion 135 for joining the node 113b.

The rotating body 132 includes a first rotating body 132a positioned below and a second rotating body 1 32b positioned above, and each is a hard rubber sphere having the same diameter force. 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 rotary shaft 133a and the second rotary shaft 133b are parallel to the longitudinal direction of the sliding play apparatus 110 and are formed horizontally. Both ends of the rotary shaft 133 are formed with thread grooves and are fastened with nuts 133c.

[0084] 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. Yes. As shown in FIG. 22, the T-shaped metal fitting 134 has a substrate portion 137 in which long holes 136, 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 part 137 at two locations. The long hole 136 is passed through the rotary shaft 133, and the rotary shaft 133 is formed to be movable up and down in the long hole 136. That is, the shaft diameter of the rotating shaft 133 is formed to be smaller than the hole width of the long hole 136, and the nuts 133c installed at both ends of the rotating shaft 133 are fastened at positions separated from the substrate portion 137. ing. The overhanging portion 138 extends in parallel with the longitudinal direction of the sliding playground equipment 110. It is joined to the lower blade 113b by the joining part 135.

As shown in FIG. 22, the joining portion 135 is a portion that joins the T-shaped bracket 134 and the lower layer blade 113b. In the joining portion 135, an absorbent material 140 is threaded through 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 via 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 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 movement in the longitudinal direction is allowed. In addition, since both end sides of the absorbent material 140 are formed thicker than the central portion, it is possible to flexibly cope with the acting load.

[0086] According to the powerful support portion 130, when the player P moves the weight in the front-rear direction (toe side or heel side), the first rotating body 132a and the second rotating body 132b are in contact with each other while the rotating shaft 1 33 Therefore, the upper layer blade 113a and the lower layer blade 113b slide smoothly in the width direction. Further, since the absorbent material 140 is inserted, the load acting on the support portion 130 is absorbed, and the upper blade 113a and the lower blade 113b are allowed to move in the longitudinal direction. As a result, like the sliding play equipment 1 according to the first embodiment, the second edge of the upper blade 113a and the lower blade 113b can be caused to bite into the sliding surface by moving the weight of the player P. You can turn.

[0087] 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, causing the idle rotation. there's a possibility that. 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. As a result, 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.

[0088] In the fourth embodiment, the support portion 130 described above is used, but other forms may be used. For example, the rotating body 132 is a sphere, but may be an elliptical sphere, for example. The T-shaped metal fitting 134 is a pair of metal fittings, but may be integrally formed. Also suck The shape and material of the collecting material 140 may be appropriately set according to the play style of the player P. Further, in order to prevent wear of the long hole 136 and the rotating shaft 133, a cushioning material may be provided along the shape of the long hole 136.

As described above, the force described for the embodiment of the present invention is not limited to this, and can be appropriately changed without departing from the gist of the present invention. In addition, the usage may be used for other purposes than just games.

In the first embodiment and the second embodiment, the sliding play equipment 1 is used in substantially the same form as a snowboard. For example, an object or a person is placed on the upper plate 6 of the slide play equipment 1. A box-like body or the like suitable for placing the vehicle 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. Thus, the sliding playground equipment 1 can be operated.

[0090] Further, an object (including a person) may be placed on the box-shaped body and pulled by the nose plate 8 side (see Fig. 1). For example, when the force on the side of the arrow 62 in FIG. 16 is pulled, the load of the object placed on the box-like body acts on the blade 3 in accordance with the change in the pulling direction or the sliding surface S. As a result, the blade 3 slides and the second edge 45a in the pulling direction catches the sliding surface S, so that the sliding playground equipment 1 can smoothly follow the pulling direction. In addition, since the sliding playground equipment 1 includes the protruding portion 43, it is possible to prevent a fall due to a sudden operation.

[0091] In addition, the sliding play 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 (b) of Fig. 2). As a result, the sliding playground equipment can be reduced in weight by reducing the members constituting the sliding playground equipment as much as possible, and can be adapted to air-based games.

[0092] Further, the sliding playground equipment according to the present invention is not limited to the force described in the case of sliding on the snow surface in the description of the first embodiment. Surface or water surface can also be slid.

Further, the blade 3 is used in the sliding playground equipment 1 in the description of the first embodiment, but it is also possible to provide the blade 3 in another structure that is not limited to this.
