Conventional swings have a structure in which a chain, etc. is suspended from a support frame, and a board is suspended horizontally at the bottom end of the two chains.The user sits on this board, holds the chain with both hands, and stretches both legs. The swing was designed to use bending and stretching and shifting the center of gravity. In the case of this type of conventional swing, you have to use both arms to firmly grasp the chain so that you don't fall off, and the role of both arms is to hold the weight It only served as a fulcrum to support the movement of the swing, and did not actively contribute to the movement of the swing.

The purpose of this invention is to be able to hold the swing safely without relying on the strength of the arms, and to also be able to use the strength of the free arms to row the swing. To provide a completely new and safe swing that allows one to fully enjoy swinging.

Hereinafter, the present invention will be explained in detail with reference to embodiments shown in the drawings.

FIGS. 1 to 3 illustrate an embodiment of the present invention, and the swing, which is designated as a whole by reference numeral 1 in the figures, is composed of a support frame 2 and a swing frame 3.

In the case of this embodiment, the support frame 2 is integrally formed from a metal pipe or the like in an elongated U-shape with an open bottom end, and the horizontal part 4 at the top end is connected horizontally via mounting fittings 5, 5. It is rotatably supported on a horizontally suspended frame 6.

A reinforcing plate 8 is provided in the middle of the support frame 2 to connect the left and right arms 7, 7.
Care has been taken to ensure that the distance between them does not widen. 2
The lower ends of the arms 7, 7 are gently curved toward the front, and a grip 9 is provided at the tip.

Grip 9 near the open end of the two arms 7, 7,
A support shaft 10 is horizontally suspended between the base ends of the curved portions 7a, 7a which curve in nine directions, and is rotatably supported by the arms 7, 7.

A frame 11 made of metal or the like and forming the swing frame 3 extends integrally with the support shaft 10 from behind both ends of the support shaft 10 . The frame 11 is integrally made of a metal pipe and has a substantially U-shaped shape with an open front when viewed from the side, a seat 12 is provided at the lower end, and a backrest 13 is horizontally suspended in the middle.

On the other hand, a pair of brackets 10a, 10a are protruded from the lower end side of both ends of the support shaft 10, and shafts 10b, 10a are provided on the brackets 10a, 10a.
The protection frame 14 hangs down rotatably via b. The protective frame 14 is formed from a metal pipe or the like into a substantially U-shape, and a locking member 15 is attached to the lower end thereof.

The locking member 15 is fixed to the lower end of the protective frame 14 as shown in FIGS. The lever 18 is rotatably supported via a shaft, and the lever 18 is provided with a hook 19. Then, the lever 18 is attached to a locking fitting 20 that is bent upward and fixed to the distal end side of the seat 12 of the frame 11 of the swing frame 3.
By rotating upward from the state shown in FIG. 2 to the state shown in FIG. 3, the hook 19 can be locked to the locking fitting 20, and the protective frame 14 can be fixed.

Next, a method of using this embodiment configured as above will be explained.

The user first releases the locking member 15 and then locks the protective frame 14 into the brackets 10a, 10a.
The user rotates the seat 12 forward about the shafts 10b, 10b, positions the body between the protective frame 14 and the frame 11, and sits down on the seat 12. In this state, place the locking metal fitting 20 between the legs, rotate it to the front of the seat 12, pull the open protective frame 14 toward you, and hook the hook 19 of the locking member 15 to the locking member 20. By rotating the lever 18 upward, it is locked against the frame 11. In this state, the user grasps the grips 9 at the tips of the arms 7, 7 from the outside of the protective frame 14 with his left and right hands, as shown in FIG.

At this time, the tips of the left and right arms 7, 7 become a curved part 7a and extend in front of the user, so
The user can hold the grip 9 with both left and right hands extended forward.

In this state, if the hand gripping the grip 9 is tightened and pulled, the swing frame 3 will swing around the support shaft 10, and the user's body will begin to swing. The vibration of the swing frame 3 is transmitted to the instruction frame 2, which is integrated with it.
The instruction frame 2 begins a large pendulum movement with respect to the frame 6 together with the swing frame 3 on which the user is placed.

In this way, the user can use the force of his/her arms to row the swing, but the front part is protected by the protective frame 14, the rear part is supported by the backrest 13, and the user's Since the left and right hands are fixed to the grip 9, there is a certain sense of stability and it is completely safe, allowing the user to swing freely and enjoy the variety of swings.

5 to 8 illustrate an embodiment of the present invention. In this embodiment, the support frame 2 consists of independent left and right arms 7, 7, and the upper end of each arm 7 is , is suspended from mounting fittings 5, 5 fixed to the frame 6 by means of an S-shaped fitting 21 via a gourd fitting 22. The middle portions of the left and right arms 7, 7 are kept parallel and integrated by a plurality of reinforcing frames 23 that intersect in an X-shape. In the case of the example shown in FIG. 1, the mounting structure of the support shaft 10 was directly rotatably supported on the arms 7, 7, but in the case of this embodiment, the structure is shown in FIG. It uses a similar structure.

That is, the support shaft 10 is formed from a metal pipe,
Metal bearings 10a are press-fitted into both ends, and a support plate 2 is placed on the arm 7 side from the outside.
The pin 25 to which 4 is fixed is inserted, and the support plate 24
is fixed to the arm 7 by spot welding or the like, and the support shaft 10 is supported by rotatably supporting the pin 25 on the metal bearing 10a.

Furthermore, the structure of the locking member 15 is also different. That is, since the lock member 15 has a substantially U-shaped frame 16 fixed to the lower end of the protective frame 14 as in the previous embodiment, a lock arm 26 forming a crankshaft is disposed between the open ends of the frame 16. horizontal part 26a of
is rotatably supported. The tip of the horizontal portion 26a is a hook 26b bent at a right angle.
The other end is a grip 26c. On the other hand, on the front end side of the seat 12, a protruding piece 27 is attached to the frame 11.
A long hole 27a is formed in the vertical direction in this projecting piece 27. The size and length of the elongated hole 27a are such that the hook 26b can be freely fitted in the vertical position.

Therefore, the protective frame 14 holds the seat 12 while keeping the grip 26c substantially vertical as shown in FIG.
After fitting the hook 26b into the elongated hole 27a, as shown in FIG.
If you turn c downward, the hook 26b will face upward,
It is locked to the protrusion 27 and therefore to the frame 11 and will not come off in a natural state.

This embodiment is different only in the structure of the support frame and the structure of the locking member, and its method of use is exactly the same as the embodiment shown in FIGS. 1 to 4, and the same effects can be expected.

9 and 10 show the frame 11 of the swing frame 3.
In the embodiment shown in FIG. 9, there is a U-shaped cross section on the back of the support shaft 10 rotatably supported between the left and right arms 7, 7. a bearing member 28 of a predetermined length having
is fixed, and the frame 11 is supported by the bearing member 28.

In addition, in the case of the embodiment shown in FIG.
A structure is adopted in which the frame 11 and the frame 11 are rotatably supported by a hinge 29.

Regardless of which structure is adopted, the swing frame 3 can be swingably attached to the left and right arms 7, 7.

11 to 13 illustrate other embodiments of the present invention, the overall structure of which is shown in the fifth embodiment.
It is completely similar to the embodiment shown in the figures, with the only difference being the locking member.

That is, as shown in FIGS. 12 and 13, a protruding piece 30 is provided at the lower end of the protective frame 14 to protrude toward the seat 12, and a notch 30a is provided at the upper end of the protruding piece 30. It is formed. A lock member 31 is provided at the tip of the frame 11 forming the seat 12. The locking member 31 consists of a base 32 fixed to the frame 11 side and a locking pin 33, and the locking pin 33 is constantly applied with a force in the direction of fitting into the base 32 by a spring (not shown). Further, an opening into which the protruding piece 30 can be fitted is formed in the front of the base 32. Therefore, by pulling the lock pin 33 upward against the spring pressure, and in the raised state, the protruding piece 30 is inserted into the base 32. When the lock pin 33 is fitted into the lock pin 30 and the lock pin 33 is released, the tip of the lock pin 33 is fitted into the notch 30a of the protrusion 30, and the protection frame 14 can be reliably locked.

Even if such a structure is adopted, it is possible to expect the same operation and effect as the embodiments shown in FIGS. 1 to 4.

As is clear from the above description, according to the present invention, the tips of a pair of arms that freely hang down from the swing frame are curved forward to form a grip, and the lower ends of these arms are The structure is such that a swinging frame is attached nearby and a removable protective frame is attached to the swinging frame, allowing people with walking disabilities to swing freely using the power of their arms. The user's body is stabilized by gripping the grip with his or her arm, and the protective frame securely holds the user's body from falling, providing a sense of stability and making it completely safe for both children and the elderly. Swings are available for use.
