Description

[Technical Field]

[0001] The present invention relates to a swing whose seat always remains substantially horizontal. [Background technology]

[0002] A swing is a widely known playground equipment in which the left and right sides of the seat are suspended by wires or chains, etc., and swing back and forth around the upper end of the wires or chains as a fulcrum. Patent Document 1 below discloses an idea for a swing playground equipment that can be ridden in either an upright or reclined position. In recent years, swings similar to thrill rides, with the seat suspended from a high place, have also become a type of attraction. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3250248 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in conventional swings, the seat remains approximately perpendicular to the fulcrum. For this reason, in the case of a typical sitting-type swing, the player faces upward near the highest point in the front, and cannot appreciate the surrounding scenery unless they intentionally lower their head. Also, near the highest point in the rear, the player faces downward, and cannot appreciate the surrounding scenery unless they intentionally raise their head. This poses a problem, particularly for swings suspended from high places, in that the appeal of being at a high altitude cannot be fully utilized.

[0005] The present invention has been made in view of the above circumstances, and has as its object to provide a swing in which the seat portion always remains substantially horizontal when swinging. [Means for solving the problem]

DETAILED DESCRIPTION OF THE INVENTION

[0009] An embodiment of a swing 80 according to the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram showing the overall configuration of a swing 80 according to the present invention. FIG. 2 is an enlarged side view of the swing 80 according to the present invention at the rear position, FIG. 3 is an enlarged side view at the lowest position, and FIG. 4 is an enlarged side view at the frontmost position. FIG. 5 is an enlarged front view of the swing 80. FIG. 6 is a diagram explaining the positional relationship between the first shaft 32a, the second shaft 32b, and the third shaft 32c of the chair body 30. While the swing 80 is shown here as being applied to a thrill ride suspended from a high place, the present invention is not limited to this application and can also be applied to swings of a general height. Here, the term "side" refers to the left-right direction when the swing 80 swings forward and backward.

[0010] First, the swing 80 of the present invention shown in Figure 1 has a chair body 30 on which a player sits, a support part 20 from which the chair body 30 is suspended, and wires (first wire 40a, second wire 40b, third wire 40c) that connect the chair body 30 and the support part 20.

[0011] As shown in FIGS. 2 to 4, the chair body 30 has a seat portion 30a and a backrest portion 30b. First shafts 32a are provided on the left and right sides at the front of the seat portion 30a, facing laterally. Second shafts 32b are provided on the left and right sides at the bottom of the rear side of the seat portion 30a, facing laterally. Third shafts 32c are provided on the left and right sides at the rear of the backrest portion 30b, facing laterally. Furthermore, first support shafts 22a, second support shafts 22b, and third support shafts 22c are provided on the upper part of the support portion 20, facing laterally, in one-to-one correspondence with the first shafts 32a, second shafts 32b, and third shafts 32c. In addition, the positional relationship between the respective axes of the first support axis 22a, the second support axis 22b, and the third support axis 22c on the support portion 20 side (the respective fulcrums of the first wire 40a, the second wire 40b, and the third wire 40c described below) is the same as the positional relationship between the respective axes of the first axis 32a, the second axis 32b, and the third axis 32c on the chair body 30 side (the respective mass points of the first wire 40a, the second wire 40b, and the third wire 40c) when viewed from the side.

[0012] Next, the positional relationship between the respective axes of the first axis 32a, the second axis 32b, and the third axis 32c (the same applies to the positional relationship between the respective axes of the first support axis 22a, the second support axis 22b, and the third support axis 22c) will be described in more detail using FIG. 6 . Here, the axis of the first axis 32a is defined as point A, the axis of the second axis 32b is defined as point B, and the axis of the third axis 32c is defined as point C. The side connecting points A and B is defined as side AB, the side connecting points B and C is defined as side BC, the angle between the horizontal line and side AB is defined as θ, and the angle between the horizontal line and side CB is defined as θ'. Also, as shown in FIG. 1, the swing angle of the chair 30 is defined as φ. When the swing 80 swings by natural fall, the highest point reached by the chair 30 is equal to the starting point near the stage 10 shown in FIG. 1.

[0013] First, the positions of the first axis 32a, the second axis 32b, and the third axis 32c must be such that the angles θ, θ′ and the swing angle φ satisfy the following upper limits. θ<(90°-φ), θ'<(90°-φ)...(1) If this condition is not met, any of the wires 40a, 40b, 40c may interfere with any of the shafts 32a, 32b, 32c, 22a, 22b, 22c during swing, resulting in a safety problem. It is preferable that θ<(90°-φ-5°) and θ'<(90°-φ-5°).

[0014] Next, it is preferable from the viewpoint of strength that the first axis 32a, the second axis 32b, and the third axis 32c are located close to the chair body 30, i.e., the seat portion 30a and the backrest portion 30b. Therefore, it is preferable that the angle between the sides AB and CB, i.e., the angle ABC, be bent in the same direction as the chair body 30, as in the case of a general chair. The angle ABC is in the range of 90°≦130° (2). do.

[0015] In order to satisfy the above equations (1) and (2), θ and θ' must be acute angles, and when the first axis 32a is provided at the front side of the seat portion 30a, the second axis 32b is structurally located below the seat portion 30a in a side view, and the third axis 32c is located behind the backrest portion 30b.

[0016] Furthermore, in many general chairs, the backrest 30b is longer than the seat 30a. Therefore, when the length of the side AB is L1 and the length of the side BC is L2, the ratio of the length L1 to the length L2 is, as in the case of a general chair, It is preferable that the range is 1.5≦(L2 / L1)≦2.0.

[0017] Next, the relationship between the angles θ and θ' is expressed by the following equation (3): θ'=180°-θ-(angle ABC)...(3) Therefore, the angles θ and θ' must satisfy the above formulas (1) to (3), and The range is 25°≦θ≦45°, 25°≦θ'≦45° (4). do.

[0018] Here, the numerical values ​​of each part that are particularly suitable for the swing 80 according to the present invention are as follows: swing angle φ is 45°, angle θ is 30°≦θ≦35°, angle θ' is 35°≦θ'≦40°, angle ABC between sides AB and CB is 110°≦angle ABC≦120°, and the ratio of length L1 of side AB to length L2 of side BC is (L2 / L1)≈1.8.

[0019] A first wire 40a is connected between each of the left and right first shafts 32a and the first support shaft 22a so as to be rotatable relative to the first shaft 32a and the first support shaft 22a. A second wire 40b is connected between each of the left and right second shafts 32b and the second support shaft 22b so as to be rotatable relative to the second shaft 32b and the second support shaft 22b. A third wire 40c is connected between each of the left and right third shafts 32c and the third support shaft 22c so as to be rotatable relative to the third shaft 32c and the third support shaft 22c. Thus, the chair body 30 is suspended by a total of six wires: three pairs of left and right first wires 40a, second wires 40b, and third wires 40c. In order to prevent the chair body 30 from swaying sideways, it is preferable that the first wire 40a, the second wire 40b, and the third wire 40c have an inverted V shape in front view, with the support column 20 side (the first to third support column axes 22a to 22c side) being wider, as shown in Figure 5.

[0020] If the swing 80 according to the present invention is an attraction similar to a thrill ride, the support column 20 will be a tall building as shown in Fig. 1, the first to third support column axes 22a to 22c will be located at a high place, and a stage 10 will be provided for players to sit on the chair body 30. As shown in Fig. 5, the chair body 30 is preferably a bench so that multiple players can ride at once, and fall prevention devices 12 such as body harnesses and safety bars will be provided to prevent players from falling.

[0021] Next, the operation of the swing 80 according to the present invention will be described. Note that this description will be given assuming that the swing 80 is an attraction similar to a thrill ride. First, the chair 30, which is at the lowest point, is pulled up above the stage 10 by a towing rope (not shown) and hooked. Next, the stage 10 is moved forward, and the player is seated on the chair 30. Next, safety measures are taken by activating the fall prevention device 12, such as by closing the safety bar. Next, the stage 10 is moved backward to remove it from the swing path of the swing 80. Next, the hook of the chair 30 is released. As a result, the chair 30 falls naturally under its own weight and performs a swing motion about the first support shaft 22a, the second support shaft 22b, and the third support shaft 22c. In this case, the axes of the first, second, and third shafts 32a, 32b, and 32c on the chair body 30 are in the same position as the axes of the first to third support shafts 22a, 22b, and 22c that suspend them when viewed from the side. Therefore, if the seat 30a of the chair body 30 is configured to be approximately horizontal, the chair body 30 will rock while maintaining the same posture with the seat 30a always facing approximately horizontal, as shown in Figures 2, 3, and 4. This allows the player to always face forward and enjoy the surrounding scenery without having to raise or lower their head, even near the peak of the rocking motion. Furthermore, since the wires are out of sight when rocking forward, the sense of fear is even greater.

[0022] As described above, the swing 80 according to the present invention has three shafts, the first shaft 32a, the second shaft 32b, and the third shaft 32c, on the chair body 30, and the first support shaft 22a, the second support shaft 22b, and the third support shaft 22c on the support column 20, which correspond one-to-one to the first shaft 32a, the second shaft 32b, and the third shaft 32c. The relative positions of the axes of the first shaft 32a, the second shaft 32b, and the third support shaft 22c are the same as the relative positions of the axes of the first support shaft 22a, the second support shaft 22b, and the third support shaft 22c, when viewed from the side. This allows the chair body 30 to swing while always facing the same direction. Therefore, if the seat 30a is configured to be approximately horizontal, the chair body 30 will swing with the seat 30a always facing approximately horizontal, allowing the player to always face forward. This allows the player to enjoy the surrounding scenery even when near the highest point of the swing.

[0023] It should be noted that the configuration, shape, dimensions, mechanism, design, etc. of each part of the swing 80 shown in this example are merely examples, and the present invention can be implemented with modifications within the scope that does not deviate from the gist of the present invention.
