[0016]

Next, a specific example of an embodiment of an entertainment vehicle according to the present invention will be described with reference to the drawings. FIG. 1 is a schematic view showing an embodiment of an entertainment vehicle according to the present invention. The entertainment vehicle 1 includes a departure platform 2, an arrival platform 3, a support cable 4, a pulley 5, and the like. .

The departure table 2 and the arrival table 3 are respectively provided on a mountain surface or the like, and the departure table 2 exists at a position higher than the arrival table 3. The departure table 2 is a place where the occupant mounts a support harness 6 as a support member connected to the pulley 5 and starts moving along the support cable 4. On the other hand, the arrival platform 3 is a place where the occupant finishes moving along the support cable 4 and removes the attached support harness 6.

The support cable 4 is arranged so as to connect the departure table 2 and the arrival table 3, and both ends thereof are fixed to a support frame 4 a on the start table 2 side and a support frame 4 b on the arrival table 3 side. Then, the pulley 5 moves along the support line 4, and the occupant also moves from the departure platform 2 to the arrival platform 3 with this movement.

The pulley 5 is detachably attached to the support cable 4 and moves along the support cable 4. Since the pulley 5 is connected to the support harness 6 worn by the occupant, the occupant also moves along the rope 4 together with the pulley 5. As will be described in detail below, the pulley 5 is configured to be easily detachable from the support 4 and to be able to adjust the moving speed with respect to the support 4.

Next, with reference to FIGS. 2 and 3, the structure of the pulley 5, which is a characteristic part of the recreational vehicle according to the present invention, will be described in detail. The pulley 5 is mounted on the support cable 4 and moves while rotating on the support cable 4, a frame 52 supporting the pulley 51 from both sides, and a pulley 51 inserted into the center of the pulley 51. , A shaft 53 functioning as a rotating shaft of the pulley 51, and a spring 58 for adjusting the moving speed of the pulley 51 with respect to the support line 4.

The pulley 51 is formed in a disk shape having a groove, receives the support 4 in the groove, and rotates and moves on the support 4 in the direction of arrow X in FIG. The material of the pulley 51 is selected from hard plastic, aluminum alloy, and steel. However, when the distance between the departure stage 2 and the arrival stage 3 is long, the pulley 51 is made of steel in consideration of the life of the pulley 51. Is preferred.

The pulley 51 is configured to rotate around a shaft 53 inserted into the center opening. An annular dry metal 54 is mounted on the center of the pulley 51 to prevent the pulley 51 and the shaft 53 from being worn.

An eccentric bolt insertion hole 53a is formed in the shaft 53, and an eccentric bolt 55 is inserted into the eccentric bolt insertion hole 53a. Further, the eccentric bolt 55 penetrates through the side surface of the frame 52 and is fixed to the frame 52. Therefore, since the shaft 53 is supported eccentrically about the eccentric bolt 55, the pulley 51 rotating about the shaft 53 also rotates eccentrically about the eccentric bolt 55. The reason for adopting such a configuration will be described later.

As shown in FIG. 2, the frame 52 supporting the eccentric bolt 55 includes two side plates 52a and 52b located on both left and right sides of the pulley 51, and a connecting portion 52c for connecting the both side plates at an upper portion thereof. It consists of.

A plurality of washers 56 are placed on the connecting portion 52c, and a spring 58 is fixed between the washer 56 and a spring holding bolt 57 as clearly shown in FIG. In this embodiment, three washers 56 are provided.

The spring 58 is formed in a plate shape having a curved portion 58 a, one end of which is fixed to the connecting portion 52 c via the washer 56 as described above, and the other end of which contacts the circumferential surface 51 d of the pulley 51. At the same time, the circumferential surface 51d is urged toward the center of the pulley 51, and the relative speed of the pulley 5 with respect to the support line 4 is adjusted by friction between the pulley 51 and the pulley 51.

As described above, the reason why the plural pieces are provided is to adjust the friction force between the spring 58 and the pulley 51 by adjusting the number of washers 56. That is, the smaller the number of washers 56, the greater the urging force of the spring 58 against the pulley 51, and the greater the frictional force between the two, thereby reducing the relative speed of the pulley 5 with respect to the support line 4.

A harness connecting portion 60 is provided below the frame 52 integrally with the frame 52. The harness connecting portion 60 is provided with three mounting holes 60a. A so-called carabiner as an annular mounting member (not shown) of the support harness 6 is mounted on any of the mounting holes 60a, and the support harness 6 and the pulley 5 are connected. The reason why a plurality of the mounting holes 60a are provided will be described later.

As shown in FIG. 2, a rubber plate 61 is adhered and fixed to the inner surface of the harness connection portion 60. As will be described later, when the harness connection portion 60 is closed, two harness connection portions are provided. 60 functions so as not to form a gap.

As shown in FIGS. 4 and 5, a side surface 52 a of the frame 52 is provided with a protrusion 62 protruding from the side surface 52 a, and a lower portion 52 a ′ of the side surface 52 a including the harness connection portion 60 is As clearly shown in FIG. 4, the edge is cut off from the upper part of the side surface 52a, and the lower part 52a 'is also provided with a projection 63.

A bolt insertion hole through which an opening / closing bolt 64 can be inserted is formed in each of the protruding portions 62 and 63. The side surface 52a and the lower portion 52a 'are formed by the opening / closing bolt 64 inserted through the insertion hole. It is connected rotatably. As a result, when the pulley 5 is used, as shown in FIG. 2, the lower portion 52a 'is positioned with respect to the side surface 52a so that the distal ends of the left and right harness connection portions 60 are closed. In this case, the opening / closing bolt 64 is loosened, and the lower portion 52a ′ is rotated in the direction indicated by the two-dot chain line in FIG.

Next, the eccentric structure of the pulley 5 will be described mainly with reference to FIGS. A ring-shaped carabiner (not shown) as a connecting member for connecting the pulley 5 of the support harness 6 for supporting the occupant to the pulley 5 in the state of FIG. 5 and the passenger are integrated.

Here, a case where the carabiner is attached to the center hole of the attachment hole 60a will be described. When the carabiner is mounted in the center hole of the mounting hole 60a, the weight of the occupant and the support harness 6 is applied to the mounting hole 60a via the carabiner as a force of F1 as shown in FIG. Then, since the pulley 51 and the shaft 53 are supported by the frame 52 via the eccentric bolt 55, a straight line connecting the center of the eccentric bolt 55 and the action point F1 in the central hole of the mounting hole 60a to 2 The pulley 51 moves so that the direction becomes parallel to the vertical direction, and the state shown in FIG. 6 is obtained.

When the pulley 5 moves in the lower right direction along the support cable 4 in the state shown in FIG. 6, the eccentric bolt 55 keeps the position shown in FIG. 51 rotates around the eccentric bolt 55 via the shaft 53, but since the eccentric bolt 55 and the pulley 51 are eccentric, the pulley 51 moves on the support line 4 while rotating eccentrically. . One of the purposes configured in this way is to absorb the upward and downward swings of the traveling support line 4 by the pulley 5 and to adjust the brake strength by the spring 58.

That is, as shown in FIG. 7, if the mounting position of the carabiner is a hole on the right side of the mounting hole 60a, the gravity F2 of the occupant and the support harness 6 is applied to the hole on the right side. Then, since the pulley 51 and the shaft 53 are supported by the frame 52 via the eccentric bolt 55, the entire frame 52 is inclined rightward, and the center of the eccentric bolt 55 and the mounting hole 60a are The pulley 51 moves so that the straight line connecting the action points of F2 in the center hole to 2 is parallel to the vertical direction, and the state shown in FIG. 7 is obtained.

Then, the dimension H 2 of FIG. 6, which determines the strength of the elastic force of the spring 58, is longer than the dimension H 1 of the same portion in FIG. 6, and the elastic force of the spring 58, that is, the attachment to the pulley 51. Since the power is weakened and the frictional force therebetween is reduced, the relative speed of the pulley 5 with respect to the support line 4 is increased.

On the other hand, if the mounting position of the carabiner is a hole on the left side of the mounting hole 60a as shown in FIG. 8, the gravity F3 of the occupant and the support harness 6 is applied to the hole on the left side. Then, for the same reason as described above, the entire frame 52 is tilted leftward, and the straight line connecting the center of the eccentric bolt 55 and the action point of F3 in the center hole of the mounting hole 60a is parallel to the vertical direction. The pulley 51 moves so as to be as shown in FIG.

Then, the dimension H3 of FIG. 6, which determines the strength of the elastic force of the spring 58, is shorter than the dimension H1 of the same part in FIG. Since the urging force increases and the frictional force between the two increases, the relative speed of the pulley 5 with respect to the support line 4 decreases.

As described above, by changing the mounting position of the carabiner in the mounting hole 60 a of the harness connection portion 60, the displacement of the spring 58 changes, and the frictional force between the spring 58 and the pulley 51 changes. The relative speed of the pulley 5 with respect to the support line 4 changes. Therefore, when it is desired to change the relative speed of the pulley 5 with respect to the support cable 4 in consideration of the passenger's weight, the wind direction of the difference in the use of the recreational vehicle 1, and the humidity, etc. This can be accommodated by the mounting position of the carabiner.

Next, a description will be given of an operation in which the occupant performs recreational movement using the recreational vehicle 1. First, on the departure table 2, the passenger wears the support harness 6 by himself or with the help of an assistant. Here, if necessary, the urging force of the support cable 4 by the spring 58 is adjusted as described above, and the speed between the support cable 4 and the pulley 5 is adjusted. Then, the support harness 6 worn by the occupant is connected to the pulley 5 to prepare for the start of movement.

When the occupant starts moving as if jumping down from the end of the departure table 2, the occupant descends along with the pulley 5 along the support cable 4 by gravity. Then, the passenger continues to descend along the rope 4, and finally completes the descending at the arrival platform 3, and the passenger removes the support harness 6 by himself or with the help of an assistant to complete the movement. To

After the movement is completed, the pulley 5 is detached from the support cable 4 and transferred to the departure table 2 to prepare for the next use. By preparing a plurality of pulleys 5, it is possible to use the entertainment vehicles without lowering the operating rate.
