[0001]

[Industrial applications]

 The present invention relates to swings, and in particular to swings for young children.

[0002]

[Prior art]

 A single-seat swing installed in a conventional nursery or amusement park has a structure in which a wooden or hard synthetic resin seat plate is suspended from the lower ends of two metal chains. Chain mounting holes are provided on the left and right of the seat plate. More recently, there have been the following prior art disclosure technologies regarding swings. Japanese Unexamined Patent Publication No. Hei 2-203887 "Playing device and safety structure for playing device" This invention is characterized in that this chain is extended under load by using a chain embedded in an elastic polymer material. It is a game device. [Patent Document 1] Japanese Patent Laid-Open No. 5-84361 "Blanco" This invention is a swing having a structure in which a rope penetrates through the center of a substantially U-shaped seat plate that forms a stool horizontal portion and is suspended. This is a device of the applicant of the present invention, which has a structure in which a rope is inserted through a central hole of the rubber tube and a suspension is used as a rubber tube for the seat.

[0003]

[Problems to be solved by the device]

 The conventional swing described above has the following problems other than the invention of the applicant. Swing play equipment swing is a metal chain that has problems with materials that are corroded or rusted, and parts such as seat plates made of hard material may cause injury if it hits a person. There was a problem that fear could not be avoided. Swinging causes swinging and rocking back and forth, which causes unpredictable movements of infants, etc.When a hard iron chain or a seat plate collides with or touches an infant's body, unexpected movements may occur. There was a risk of an accident. In addition, since the lateral width of the seat plate is designed to be considerably wider than the waist width of the infant as in the above invention, there is a risk of skidding on the seat plate and the risk of rollover. Further, in the configuration in which the horizontal portion is provided on the seat plate, a large load is applied to the bending portion of the rope, and that portion may be weakened. It is preferable for the swing to be designed individually according to the body shape, age, and grip strength of the user, such as the shape and feel of the part to be gripped by hand, the softness and width of the seated part, the height, and the weight. However, since it is a playground equipment that is often installed in public places, it cannot be individually handled due to its nature, but at least the infants are required to have a proper and safe swing.

[0004]

[Means for Solving the Problems]

 The present invention addresses and solves this demand, and is a swing in which both ends of a rope are hung and suspended in a substantially U-shape, and a sitting portion is formed in the intermediate hanging portion of the swing. The rope is a flexible synthetic resin rope, the seat is a flexible body that can be bent to a predetermined extent, and the rope passes through the middle of the seat or the seat is placed. It provides a characteristic swing.

The stool is a flexible body that is curved to a predetermined extent and has a convex and concave surface, through holes on the left and right, and thin flexible ridges on the periphery. A structure in which the waist part is loosely fitted and placed around the back side, or a coil coil made of rubber or a string made of the same material as the rope (bracket) is braided or the coil is wound to a predetermined limit. It is a flexible body that can be bent.

The predetermined limit of the bending of the sitting portion is limited to a material so that the sitting portion is bent into a circle having a diameter equal to the distance between the left and right ropes.

[0007]

【Example】

 FIG. 1 is a partial sectional perspective view showing an embodiment of a swing according to the present invention. In the swing of FIG. 1 shown in the embodiment, the hooks 2 at both ends of one rope 1 are hung on a beam (not shown) and suspended in a substantially U-shape, and a waist portion 3 is provided at the intermediate hanging part. The formed swing, the rope 1 is a flexible synthetic resin rope, the seat portion 3 is a flexible body that can be bent to a predetermined limit, and the rope 1 is mounted by loosely mounting the seat portion 3. Shows a swing. The rope 1 is made of a flexible material, and a rope shape is preferable because it is easy to grip. For example, a rope made of a synthetic resin fiber such as the trademark "Cremona rope" is woven. The rope 1 may be covered with a heat-shrinkable tube for prevention of dirt and reinforcement.

The seating portion 3 is formed with irregularities 31 for preventing slippage on the front surface, through holes 32 and 33 are provided on the left and right sides, and thin and flexible ridges 34 are provided on the periphery, and a loading groove for the rope 1 is provided on the back surface. It is a soft body which is provided with 35 and is bendable to a predetermined limit. The rope 1 passes through the through-holes 32 and 33 of the stool 3 and goes around the back side and fits in the loading groove 35, that is, the stool 3 is loosely mounted. The groove 35 on the back surface of the seat portion 3 is for stably inserting the rope 1 and preventing the rope 1 from slipping. The design of this groove 35 can be changed to a horizontal through hole, but if it is a through hole, there are problems such as the trouble of mounting the rope 1, the difficulty of checking the back surface condition, and the difficulty of draining water. Further, since there is a problem in loose fitting of the seat portion 3, the groove has been improved to be open.

The degree of bending of the seat 3 needs to have a predetermined bending limit. It is not too flexible and certain limits are important for safety. The elastic material is limited and the structure is devised so that the bending degree is up to the shape of a circle having a diameter between the left and right ropes 1. The material can be selected from synthetic rubber material, elastic polymer material, elastic synthetic resin mixed with nylon fiber, etc., and the structure is as follows. It is achieved by forming. Further, in order to maintain this bending degree, the thick portion 11 is formed so that the seat portion 3 does not rise in the middle of the lower portion of the rope 1. The thick part 11 is braided with a cord made of the same material as the rope 1 to make it thicker. Further, the stopper 12 is formed on the seat 3 with a cord made of the same material as the rope 1.

Next, a second embodiment shown in FIG. 2 will be described. Basically, like the first embodiment, it is a swing in which a hanging member 2 provided at both ends of one rope 1 is hung in a substantially U shape, and three sitting portions are formed in the intermediate hanging portion. The rope 1 is a flexible synthetic resin rope, and the seat portion 3 is a coiled portion 40 of a thick rubber cord or a coiled portion 40 of a cord made of the same material as the rope 1 so as to be a thick portion and can be bent to a predetermined limit. It is a soft body. Although not shown, the thick portion of the coil winding 40 may be double wound to form a thicker portion. When coiled around a curved intermediate hanging part, the upper surface side (the part to sit on) is narrow, so a solid surface is formed on the upper surface and it stabilizes. Since the rope 1 loosely penetrates through the middle (inside the coil) of the sitting portion 3 having the above-mentioned structure, the coil winding fits to the waist by falling sideways depending on the load of the waist. It should be noted that the end of the coil winding 40 is gradually thinly wound toward the end so that the connection does not feel uncomfortable.

Next, a third embodiment shown in FIG. 3 will be described. In the embodiment shown in FIG. 3, a rope 41 made of the same material as that of the rope 1 is woven into the intermediate hanging portion of the rope 1 while maintaining a bendability of a predetermined limit to form a thick portion 41. In this braiding, the narrowest width at the bottom of the hanging part (width around the buttocks) is knitted thick and hard, and as it goes upward and leftward, it is knitted loosely and thinly to obtain the desired bendability. The method of knitting is called ball sliding, and the rope 1 is twisted in the opposite direction and a string is passed through the gap, so that it can be firmly integrated.

The above is merely an example, and the present invention is not limited to these. Further, although not shown, it is possible to freely change the design of the contour shape of the seat, the material of the rope, and the details.

The swing according to the present invention having such a configuration is particularly suitable as a play equipment at an early childhood education site such as a nursery school, and is used by hanging the hook 2 on a beam as in the past. The swing is hung and the infant swings freely and gets on and off, but since the rope 1 is rope-shaped, it is easy to hold and is safe to hit, and the seat 3 is a soft body, so it is a little rough. It has a structure that will not hurt even if you shake it. Moreover, since the seat 3 does not have any metal or plate embedded therein, there is no danger of exposing the hard body. Since the stool section 3 is flexible, even if a lightweight infant rides on a small butt, the stool section 3 will be deformed into the shape of the butt, and will fit and be stable. In addition, since the stool portion 3 has a bending limit, even when the user stands and stands on his / her feet, the feet are not caught in the rope 1.

[0014]

[Effect of device]

 The swing according to the present invention having the above configuration and operation has the following unique technical effects. Since the stool is a soft body that fits the waist of the infant, it is possible to prevent the infant from slipping off or being injured by hitting it. The combination of the stool and the rope is a combination of simply passing the rope through the stool without using bolts or nuts, so it is easy to manufacture. With this configuration, it is easy to assemble in the field, and the risk of breakdown and damage is extremely low. Since one rope passes under the seat, there is no distortion or twist of each rope unlike the conventional two ropes, and the shaking is orderly. Since the rope bends and the load is applied to the entire rope, there is no load on the part that bends, so overall durability is excellent. The number of parts is small and the manufacturing cost can be reduced, which is economical. As described above, the swing of the present invention is a very useful and safe playground equipment for infants, and has extremely high practical value.
