It has dynamic links 56R and 56L, and a player suspending means 52 installed in the suspension lower portion 50 to hold the player.

Further, the track pipe 10 according to the present invention has a substantially circular cross section as shown in FIG. 2, and its diameter is about 10 cm to 15 cm. It is preferable that the track pipes 10 are connected to each other by the flange portion 18. However, in the present invention, the upper pulley 34 and the lower pulley 44 provided in the main body 40 abut on the upper and lower sides of the track pipe 10 and slide. Therefore, it is preferable that the flange portion 18 is provided in the left-right direction so as not to interfere with the sliding of the upper pulley 34 and the lower pulley 44. A guide plate 12 having a predetermined height parallel to the axis of the track pipe 10 is fixed above the track pipe 10 over the entire line. Further, for example, suspension plates 14 are fixed to the guide plate 12 at predetermined intervals, and the track pipe 10 is fixed to the holding rail 16 via the suspension plate 14. Then, by fixing the holding rail 16 to a support (not shown) erected from the ground or the like, a sliding track of the sliding playset 80 is constructed. It should be noted that the gliding track is provided with a gradient as a whole, and curves, ups and downs of a predetermined head, and the like are formed. Further, it is preferable that the track pipe 10 has a loop shape by connecting the start point and the end point. Then, the sliding portion 82 is slid from the highest point to the lowest point by gravitational acceleration, with the vicinity of the highest point on the sliding track as the start point and the vicinity of the lowest point as the stop point (end point). The sliding portion 82 is pulled up from the lowest point (end point) to the highest point (start point) by human power or a predetermined power.

Next, the sliding portion 82 of the sliding playset 80 according to the present invention will be described. Here, FIG. 3A is a front view of the sliding portion 82, FIG. 3B is a side view, FIG. 3C is a top view, and FIG. 3D is a bottom view. .. First, the main body 40 of the sliding portion 82 includes an arm plate 30, and the arm plate 30 has left and right arms 32L and 32R extending so as to hold the track pipe 10. Then, as shown in FIG. 1, the guide plate 12 is located in the gap between the arms 32L and 32R. Therefore, the arm plate 30 has an arc shape or a U shape having a gap at the upper part for passing the guide plate 12. When the track pipe 10 is connected by a flange portion 18 projecting in the left-right direction, it is preferable that the inner side surfaces of the arms 32L and 32R have a horizontally long shape or an elliptical shape in which the flange portion 18 does not contact.

Further, a pair of upper pulleys 34 are provided on the front sides of the left and right arms 32L and 32R, and a pair of lower pulleys 44 are provided on the lower portion of the arm plate 30. Then, the left and right upper pulleys 34 are installed with the guide plate 12 sandwiched therein and tilted at a predetermined angle toward the axial direction of the track pipe 10. Further, the lower pulley 44 is installed together with the upper pulley 34 at a predetermined angle toward the axial direction of the track pipe 10 so as to sandwich the track pipe 10 from below. It is preferable that the wheels of the upper pulley 34 have an arcuate peripheral surface so that they can rotate while abutting on both the guide plate 12 and the track pipe 10. Further, it is preferable to use the wheels of the upper pulley 34 and the lower pulley 44 made of synthetic resin, which have less vibration during sliding. As a result, the upper pulley 34 rotates while sandwiching the guide plate 12 and abutting on the upper side of the track pipe 10, and the lower pulley 44 rotates while abutting on the lower side of the track pipe 10. As a result, the sliding portion 82 (main body portion 40) is held at the four points of the upper pulley 34 and the lower pulley 44, and slides along the track pipe 10. As for the configuration of the upper pulley 34 and the lower pulley 44, two sets are connected as shown in FIGS. 3 (b) to 3 (d), and the track pipe 10 is sandwiched between the two pairs of upper pulley 34 and the lower pulley 44, respectively. It is preferable to do so from the viewpoint of gliding stability.

Further, the suspension lower portion 50 constituting the sliding portion 82 includes left and right arms 50R and 50L for holding the player suspension means 52. It is preferable to provide a cushioning member 57 at a predetermined portion of the hanging lower portion 50 to alleviate the impact when the hanging lower portion 50 and the main body portion 40 collide with each other. Then, the main body portion 40 and the suspension lower portion 50 are connected via the left and right swing links 56R and 56L. At this time, the connection between the main body 40 and the swing links 56R and 56L and the connection between the swing links 56R and 56L and the suspension lower portion 50 are rotatably connected via the swing shaft 54. As a result, the main body portion 40 and the suspension lower portion 50 are oscillatingly connected to each other via the oscillating links 56R and 56L, respectively.

Further, as the player suspending means 52 for suspending the player, any body harness or the like that can hold the player may be used. Further, if the track pipe 10 is installed at a relatively low place and there is no problem in safety, a hanging bar or the like may be used for the player suspending means 52. Here, an example in which a body harness is used as the player suspending means 52 is illustrated.

Further, a deceleration zone is provided at a predetermined position of the sliding track, for example, immediately before the stop point or in a region where the sliding speed of the sliding portion 82 becomes excessive. Here, the deceleration mechanism 60 used in the deceleration zone is shown in FIG. 4 (a) is a front view of the deceleration mechanism 60, and FIG. 4 (b) is a view of the deceleration mechanism 60 as viewed from the X direction in FIG. 4 (a). In addition, in FIG. 4B, the illustration of the fixing plate 68 is partially omitted.

The deceleration mechanism 60 shown in FIG. 4 includes a pair of left and right brake rollers 62 that are installed so as to sandwich the guide plate 12 and face the side of the track pipe 10, a bearing portion 64 that rotatably holds the brake rollers 62, and a brake. It has an elastic member 66 that urges the roller 62 to the side of the track pipe 10, and a fixing plate 68 that fixes them to the holding rail 16. Further, a brake plate 67 is installed at a position facing the brake roller 62 of the main body 40, and when the sliding portion 82 passes through the deceleration zone, the brake roller 62 comes into contact with the brake plate 67 and presses the main body 40. The sliding portion 82 is decelerated. The number of deceleration mechanisms 60 to be installed is set according to the required deceleration rate.

Next, the operation of the sliding playset 80 according to the present invention will be described. First, the track pipe 10 is fixed to, for example, a column standing on the ground or the like via a holding rail 16 and a suspension plate 14. Further, the sliding portion 82 is attached to the track pipe 10. To install the sliding portion 82, a guide plate 12 is inserted between the left and right upper pulleys 34 of the main body portion 40, and the track pipe 10 is inserted so as to be held at four points of the left and right upper pulley 34 and the lower pulley 44. .. As a result, the sliding portion 82 (main body portion 40) can slide while the upper pulley 34 and the lower pulley 44 sandwich the track pipe 10 above and below.

Then, at the time of the game, the sliding portion 82 is first positioned at the starting point near the uppermost point of the track pipe 10. The starting point is assumed to be about 5m to 10m above the ground. Further, for example, a gate stopper 20 as shown in FIG. 5 may be provided at this starting point. The gate stopper 20 includes a fixing plate 24 fixed to the holding rail 16 or the suspension plate 14, a gate arm 22 located on the left and right of the track pipe 10 and rotatably installed with respect to the fixing plate 24, and left and right gates. A stopper shaft 26 for connecting the arm 22 and contacting the guide plate 12 or the suspension plate 14 to limit the rotation of the gate arm 22, and a stopper roller 28 provided on the front side of the gate arm 22 and in contact with the main body 40. ,have. The stopper roller 28 is preferably made of a flexible material such as rubber so as to reduce the impact of the main body 40 at the time of collision.

The gate stopper 20 is normally in a closed state in which the gate arm 22 is lowered and the stopper shaft 26 is in contact with the guide plate 12 or the suspension plate 14. Then, in this state, the gate arm 22 cannot pass because it blocks the path of the sliding portion 82 (main body portion 40), and the front surface of the main body portion 40 comes into contact with the stopper roller 28 and stops. Then, in this standby state, for example, a staff member fixes the player to the player suspending means 52.

When the player is fixed to the player suspending means 52, the clerk then pushes back the main body portion 40 (sliding portion 82) by a predetermined distance and then pushes the gate arm 22 back as shown by the broken line in FIG. 5A. Rotate upward and lift. As a result, the gate arm 22 is opened and there are no obstacles on the sliding track. Then, the clerk releases the sliding portion 82 in this state, and the sliding portion 82 slides toward the lowest point by the action of gravitational acceleration. Further, in the curved portion of the sliding track or the like, the suspension lower portion 50 and the player suspending means 52 are shaken laterally by centrifugal force or the like, and the player can perform a powerful gliding.

Here, for example, when the suspension lower portion 50 is connected by one swing link, the swing angle becomes large as shown in FIG. 6B, which may be dangerous. In this respect, in the sliding playset 80 according to the present invention, by connecting the suspension lower portion 50 with the left and right swing links 56R and 56L, the swing angle is limited as shown in FIG. 6A, and the safety of the player is achieved. Can be improved.

Further, at the time of this curve or the like, the left and right upper pulleys 34 installed with the guide plate 12 sandwiched between them prevent the main body 40 from rotating (with the track pipe 10 as the axis). As a result, the posture of the main body 40 with respect to the track pipe 10 is maintained, and safe and smooth sliding becomes possible.

Further, when the sliding portion 82 passes through the deceleration zone, the brake roller 62 of the deceleration mechanism 60 presses the brake plate 67 of the main body portion 40 to increase the contact resistance. As a result, the sliding portion 82 moderately decelerates, and safe sliding becomes possible.

As described above, in the sliding plaything 80 according to the present invention, the upper slide 34 is installed so as to sandwich the guide plate 12 fixed above the track pipe 10, and the track pipe 10 is vertically oriented together with the lower left and right lower slides 44. Hold it from and slide. Then, on a curve or the like, the upper pulley 34 in contact with the guide plate 12 prevents the main body 40 from rotating. As a result, the posture of the main body 40 with respect to the track pipe 10 is appropriately maintained, and safe and smooth sliding is possible. Further, in the sliding playset 80 according to the present invention, the hanging lower portion 50 is connected by the left and right swing links 56R and 56L. Therefore, the swing angle of the hanging lower portion 50 is limited, and the safety of the player can be improved.

The configuration of the sliding playset 80, the track pipe 10, the main body 40, the hanging lower portion 50, the player suspending means 52, etc. shown in this example is an example, and the shape, dimensions, mechanism, design, etc. of each part are described in the present invention.
