[0009] An embodiment of the suspension bridge type play equipment 80 according to the present invention will be described with reference to the drawings. Here, FIG. 1 is an overall view of the suspension bridge type play equipment 80 according to the present invention. Also, FIG. 2 is a view explaining the abutment 30 and the play area 40 of the suspension bridge type play equipment 80. Also, FIG. 3(a) is a top view showing the intermediate deck 50 of the suspension bridge type play equipment 80, FIG. 3(b) is a side view, and FIG. 3(c) is a front view. Here, an example in which the intermediate part is the intermediate deck 50 is basically described, but it is not necessary to use the intermediate deck 50 as the intermediate part, and the intermediate part may be a simple bar or frame, or may be composed of only the floor frame 52. Here, an example in which the suspension bridge type play equipment 80 according to the present invention is constructed by bridging both sides of a valley is described, but the present invention is not limited to this example, and may be installed in any place, such as a river, a valley, a coastal quay, both sides of a lake, a valley, a cliff, a cave, etc. Also, it may be installed between artificial structures such as dams, buildings, steel towers, etc. Furthermore, the play area 40 of the suspension bridge type play equipment 80 according to the present invention is assumed to be located at an elevation of approximately 2 m or more above the ground surface, but is not limited to a particular elevation and may be located above the water surface, etc.

[0010] First, as shown in Figures 1 and 2, the suspension bridge-type play equipment 80 of the present invention has abutment sections 30 located at both ends and fixed to the ground, main ropes 10 suspended between these abutment sections 30, safety ropes 12 also suspended between the abutment sections 30, a number of intermediate sections (intermediate decks 50) fixed to the main ropes 10 and dividing the space between the abutment sections 30 into a number of play areas 40, and scaffolding members 42 installed in the play areas 40 to provide footholds for players.

[0011] The abutment 30 holds the suspension bridge body made up of the play area 40, and has, for example, a main tower 32 fixed to the ground, and a stage 34 which serves as the start and finish points of the suspension bridge-type play equipment 80. When fixing the abutment 30 (main tower 32) to the ground, it is preferable to have, for example, anchorages 36 connected to piles driven into the ground. When the suspension bridge-type play equipment 80 is installed on an artificial structure such as a building or steel tower, this structure will also serve as the abutment 30.

[0012] As described above, the main rope 10 and the safety rope 12 are stretched between the abutments 30. The main rope 10 is a main wire that stretches between the abutments 30 and suspends the suspension bridge body as the play area 40, and the middle part is also fixed to the main rope 10. The safety rope 12 prevents the player from falling to the ground if he steps off the scaffolding member 42, and is connected to the player and the fixed safety hooks 24a, 24b in a movable state. Since the suspension bridge type play equipment 80 according to the present invention allows players to pass each other in the middle part, multiple safety ropes 12 may be stretched. It is also preferable to stretch a staff safety rope 12a between the abutments 30 separately for use by staff in the event of a player becoming unable to move in the middle of the suspension bridge type play equipment 80 or in an emergency. Furthermore, wind-resistant ropes 14 may be installed to reduce the swaying of the suspension bridge body due to wind, auxiliary ropes 16 that support the intermediate deck 50 (middle section) together with the main ropes 10, and cross ropes 18 that act as a visual fence for players.

[0013] Next, the middle section of the suspension bridge type play equipment 80 according to the present invention will be described. The middle section divides the suspension bridge body between the abutments 30 into multiple play zones 40, and basically the type, spacing, arrangement, difficulty, etc. of the scaffolding members 42 change before and after this middle section. In addition, it is preferable that the middle section be an intermediate deck 50 equipped with a floor frame 52 having a predetermined area, vertical frames 54 extending upward from the left and right sides of this floor frame 52, and a roof frame 56 connecting the upper ends of these vertical frames 54.

[0014] In the case where the intermediate portion is the intermediate deck 50, it is preferable to fix the wind-resistant ropes 14 to the left and right of the floor frame 52, fix the main ropes 10 and the cross ropes 18 to the left and right vertical frames 54, respectively, and fix the safety ropes 12, the staff safety ropes 12a, and the auxiliary ropes 16 to the roof frame 56. By fixing the safety ropes 12 to the intermediate deck 50 (intermediate portion), this fixed portion functions as a stopper 25 that inhibits the movement of the safety hooks 24a and 24b. For this reason, the player needs to replace the safety hooks 24a and 24b at the position of this stopper 25. Therefore, a dedicated locking tool 26 required for replacing the safety hooks 24a and 24b is installed on the safety rope 12 beyond the stopper 25. In the configuration where the intermediate portion is the intermediate deck 50, the stability of the intermediate deck 50 is improved by connecting the auxiliary ropes 16, and the presence of the roof frame 56 can give the player a sense of psychological security. Furthermore, by providing a fence member 54a such as a net or fence between the front and rear vertical frames 54, players can feel more secure and the intermediate deck 50 can function as a rest area or observation space for players. Also, players can easily pass each other on the intermediate deck 50.

[0015] The area between the abutment 30 and the intermediate deck 50 and between the intermediate decks 50 are defined as the play area 40, and the scaffolding members 42 are provided therein. The method of installing the scaffolding members 42 in the present invention is roughly divided into three methods. The most common method among these is to span the floor cables 44 between the intermediate decks 50 (and between the abutment 30 and the intermediate deck 50) and install the scaffolding members 42 on the floor cables 44. In this case, floor cable connection parts 53 are provided at the front and rear of the floor frame 52 and on the suspension bridge side of the stage 34 of the abutment 30, and the floor cable 44 is spanned between the floor cable connection parts 53. The suspension bridge type play equipment 80 according to the present invention allows the type, order, arrangement, etc. of the scaffolding members 42 to be changed in order to prevent players from getting bored. Therefore, it is preferable to provide a plurality of floor cable connection parts 53 so as to accommodate various scaffolding members 42 and their arrangements. In addition, five examples of floor cable connection parts 53 are shown here.

[0016] A second method of installing the scaffolding members 42 is to install the scaffolding members 42 directly on the floor rope connection parts 53. In this method as well, the presence of multiple floor rope connection parts 53 allows for a wider variety of arrangements for the scaffolding members 42. A third method is to hold the scaffolding members 42 using the main ropes 10. In this case, the floor ropes 44 are not required during play, but these configurations are preferably provided since they can be used as a scaffold for workers when attaching and detaching the scaffolding members 42 to the main ropes 10.

[0017] Next, the scaffolding members 42 and floor ropes 44 constituting the play area 40 will be described. Here, Fig. 4 and Fig. 5 are diagrams showing an example of the scaffolding members 42 of the suspension bridge type play equipment 80. Note that in Fig. 4 and Fig. 5, configurations that are not related to the description of the scaffolding members 42 are omitted from the illustration.

[0018] First, as a basic scaffolding member 42, there is a plate material 42a stretched between two floor cables 44 as shown in Fig. 4(a). The interval between the plate materials 42a may be changed, or three or more floor cables 44 may be stretched to change the arrangement of the plate materials 42a in the left-right direction as shown in Fig. 4(b). In addition, as shown in Fig. 4(c), the plate materials 42a may be of various shapes, or instead of the plate materials 42a, logs or bellows tubes made of synthetic resin with an axis may be used. Furthermore, as shown in Fig. 4(d), a scaffolding net 42b may be used.

[0019] Another example of the scaffolding member 42 is a single-bridge-like scaffolding in which a cross beam 42c' is laid between floor ropes 44 and a long rod member 42c as the scaffolding member 42 is laid vertically between the cross beams 42c' as shown in Fig. 4(e). The long rod member 42c may be laid diagonally or multiple members may be used. The long rod member 42c may also be a log, a bellows tube, or a curved or bent rod.

[0020] As an example of installing the scaffolding member 42 directly on the floor-rope connection part 53, for example, as shown in Figures 5(a), (b), and (c), a scaffolding member 42 may be made by suspending a scaffolding rope 42d, a belt-shaped net 42e, a synthetic resin fiber belt 42f such as a suling, or a rope directly on the floor-rope connection part 53. As an example of holding the scaffolding member 42 with the main ropes 10, for example, as shown in Figure 5(d), a rope 42g may be slackly slackened and stretched between the main ropes 10 to make the scaffolding member 42, or as shown in Figure 5(e), a scaffolding member 42h may be hung from the main ropes 10.

[0021] As described above, the floor ropes 44 and the scaffolding members 42 of the suspension bridge type play equipment 80 according to the present invention are replaceable, and after a certain period of time, the scaffolding members 42 are replaced to change the type and order of the play areas 40 and the arrangement of the scaffolding members 42. At this time, it is also possible to change the position and number of the floor ropes 44 as necessary. This prevents players from getting bored with the suspension bridge type play equipment 80 according to the present invention, allowing them to enjoy it for a long period of time.

[0022] Next, the safety hooks 24a, 24b will be described with reference to Fig. 6. The safety hooks 24a, 24b used in the present invention are connected to the safety belt 20 via, for example, a strap portion 26, and the safety belt 20 is fixed to the player's body. It is preferable to use a well-known body harness or the like that holds the player's entire body as the safety belt 20. The strap portion 26 suitable for the present invention has a connection portion in the approximate center, and the connection portion and the safety belt 20 are fixed by a well-known connection member such as a carabiner, and the strap portion 26 has safety hooks 24a, 24b on both ends.

[0023] Next, the locking mechanism of the safety hooks 24a, 24b suitable for the present invention will be described. First, the locking mechanism suitable for the present invention has a latch member 27 that closes the opening of the safety hooks 24a, 24b and inserts and removes the wire (safety cord 12), a trigger 21 that releases the locked state of the latch member 27 under specific conditions, and a dedicated locking tool 26 fixed to the wire side (safety cord 12).

[0024] Next, the operation of the safety hooks 24a, 24b and the locking mechanism suitable for the present invention will be described. First, the locking mechanism suitable for the present invention allows the unlocking operation of any one of the safety hooks 24a, 24b only when both safety hooks 24a, 24b are in a locked state. Specifically, while the player is pulling the trigger 21 of one of the safety hooks 24a, 24b, the latch member 27 of the safety hook 24a, 24b whose trigger 21 is being pulled is unlocked, and the latch member 27 can be rotated. Then, for example, as shown in the safety hook 24b in FIG. 6, when the safety hooks 24a, 24b are pulled out of the safety hook 12 while pulling the trigger 21 in a state where the safety hook 24a, 24b is passing through the safety hooks 24a, 24b, the latch member 27 closing the opening rotates, and the safety hook 12 is pulled out of the safety hooks 24a, 24b, as shown in the safety hook 24a in FIG. 6. The rotated latch member 27 closes the openings of the safety hooks 24a and 24b in the rotated state, locking them and putting them into a standby state. This standby state cannot be locked unless the latch member 27 is rotated to a specified position using a dedicated locking tool 26. Also, when one safety hook 24a is in the standby state, the trigger 21 of the other safety hook 24b cannot be operated, and the latch member 27 of the other safety hook 24b cannot be unlocked by any operation. Therefore, when one safety hook 24a is in the standby state and the safety rope 12 is detached, the other safety hook 24b cannot be detached from the safety rope 12, and therefore the safety rope 12 is always passed through one of the safety hooks 24a and 24b. This ensures the safety of the players.

[0025] The latch member 27 in the standby state (safety hook 24a in FIG. 6) rotates only in a manner that draws the locking jig 26 into the hook. Therefore, by fixing the safety cord 12 in a state in which it is passed through the inside of the cylindrical locking jig 26, the latch member 27 in the standby state draws the safety cord 12 together with the locking jig 26 into the safety hooks 24a and 24b, and as a result, the safety cord 12 can be passed through the safety hooks 24a and 24b. The latch member 27 rotated by the locking jig 26 closes the openings of the safety hooks 24a and 24b and is locked in this state to enter a locked state (safety hook 24b in FIG. 6). As a result, both the safety hooks 24a and 24b are in a locked state, and the other safety hooks 24b and 24a can be unlocked.

[0026] Next, a method of using the suspension bridge type playground equipment 80 according to the present invention will be described. First, the safety belt 20 is fixed to the player's body. The strap part 26 having two safety hooks 24a and 24b is connected to the safety belt 20. Next, the latch member 27 of one safety hook 24a in a standby state is positioned on the locking jig 26 fixed to the safety rope 12 at the starting point, and the safety rope 12 together with the locking jig 26 is pushed into the safety hook 24a. At this time, the latch member 27 is unlocked by, for example, magnetism, an electric signal, or physical engagement with the locking jig 26, and becomes rotatable, and rotates while pulling the safety rope 12 together with the locking jig 26 into the safety hook 24a. As a result, the safety rope 12 is passed through one safety hook 24a, and the latch member 27 closes and locks the opening of the safety hook 24a, and the safety hook 24a is in a locked state. Then, one safety hook 24a through which the safety rope 12 has passed is moved from the position of the locking jig 26 for the replacement operation of the next safety hook 24b. Next, the trigger 21 of the other safety hook 24b is pulled to unlock the latch member 27, while the latch member 27 is rotated by the player's finger or the like only at the start to put it into a standby state. Similarly, the latch member 27 of the other safety hook 24b is positioned in the locking jig 26, and the safety rope 12 together with the locking jig 26 is pulled into the safety hook 24b. As a result, the safety rope 12 is passed through the other safety hook 24b, and the latch member 27 closes the opening of the safety hook 24b, locking it and putting it into a locked state. As a result, the safety rope 12 passes through both the safety hooks 24a and 24b, and both are in a locked state.

[0027] Next, the player enters the first play area 40 from the starting stage 34 and proceeds to the intermediate deck 50 (middle section) along the scaffolding members 42. At this time, the safety hooks 24a, 24b slide along the safety ropes 12 as the player moves. Then, when the player reaches the intermediate deck 50, the movement of the safety hooks 24a, 24b is prevented by the fixing device (stopper 25) between the safety rope 12 and the frame of the intermediate deck 50, and the player cannot proceed to the next play area 40.

[0028] For this reason, the player needs to replace the safety hooks 24a and 24b on the intermediate deck 50. This replacement operation involves the above-mentioned series of operations: detaching one safety hook 24a from the safety rope 12, passing the safety hook 24a through the safety rope 12 beyond the stopper 25 using the locking tool 26 located beyond the stopper 25, and then detaching the other safety hook 24b from the safety rope 12 and passing it through the safety rope 12 beyond the stopper 25 using the locking tool 26. This replacement operation causes the safety hooks 24a and 24b to pass through the previous safety rope 12 beyond the stopper 25. In this case, it is physically impossible for both safety hooks 24a and 24b to be released from the safety rope 12 at the same time, so the player can replace the safety hooks 24a and 24b without worrying about falling.

[0029] In addition, in conventional attractions such as suspension bridge type play equipment where players move by themselves, the safety hooks 24a, 24b are not replaced during the attraction. Therefore, if a player cannot proceed in the middle of the attraction, the following players using the same safety rope 12 as the player cannot pass the player, and a traffic jam occurs. In this respect, the suspension bridge type play equipment 80 according to the present invention allows the safety hooks 24a, 24b to be replaced on the intermediate deck 50, so that even players connected to the same safety rope 12 can pass other players or change their order on the intermediate deck 50. Furthermore, by making the floor frame 52 of the intermediate deck 50 to have a certain area, players can rest, enjoy the scenery, take photos, etc. on the intermediate deck 50 without worrying about the players behind them. This allows players to enjoy the attraction at their own pace without stress.

[0030] In this way, the player advances through the play area 40 by repeatedly changing the safety hooks 24a, 24b at the stoppers 25 provided at each intermediate deck 50. In this example, the play area 40 is a straight line, but multiple play areas 40 may be connected to the intermediate section (intermediate deck 50) to branch into multiple routes, and the player may select the route. In this case, the player can select the route by performing the above-mentioned changing operation on the locking jig 26 of the play area 40 he or she wants to advance through. Then, when the player advances through the play area 40 and reaches the stage 34 of the bridge abutment 30 at the goal point, the player removes the safety hooks 24a, 24b from the safety rope 12 at the goal point, for example, by using the locking jig 26 fixed to a wire with one end cut. Next, the player removes the safety belt 20 from his or her body to end the attraction.

[0031] As described above, the suspension bridge type play equipment 80 according to the present invention can give players a sense of fear as an attraction by mainly spanning the suspension bridge body at a high place and making the scaffolding members 42 difficult to walk on. Furthermore, the suspension bridge type play equipment 80 according to the present invention can divide the play area 40 at the middle part (middle deck 50) and change the type, order, arrangement, etc. of the scaffolding members 42. This prevents players from getting used to it or becoming bored, and allows players to enjoy it for a long period of time. Furthermore, the suspension bridge type play equipment 80 according to the present invention has a middle deck 50 (middle part) on the suspension bridge body, and the safety hooks 24a, 24b are replaced on this middle deck 50. During the replacement operation of the safety hooks 24a, 24b, players can overtake each other or change their order. This allows players to enjoy the attraction at their own pace without stress. Furthermore, players can take a rest, enjoy the scenery, take photos, etc. on the middle deck 50 without worrying about the players behind them.

[0032] In addition, the configurations, shapes, dimensions, mechanisms, designs, etc. of each part of the suspension bridge-type play equipment 80, abutment 30, intermediate deck 50, scaffolding members 42, 42a to 42h shown in this example are only examples, and the present invention can be modified and implemented within the scope that does not deviate from the gist of the present invention.
