Description

Swing that moves using a pulley {SWING USING PULLEY}

One embodiment of the present invention relates to a swing that moves using a pulley.

In existing swings, it is common for one person to sit on the swing and have another person push the swing or ride alone by kicking the floor with their feet. If you ride with someone else pushing you, you can ride comfortably without putting in any effort, but there are times when there is no one around, and riding alone can be difficult for the elderly.

Therefore, the purpose of this invention is to provide a swing that even the elderly and infirm can ride comfortably by themselves and with little effort.

The purpose of one embodiment of the present invention is to provide a swing that can be moved using a pulley.

A swing that moves using a pulley according to an embodiment of the present invention to achieve the above object includes a seat 110 on which the user sits; A crossbar (120) from which the swing hangs; A support bar 130 supporting the cross bar 120 from the ground; A vertical bar 140 connecting the pedestal 110 to the cross bar 120; A footrest 150 that can be pushed by the user; A slide on which the footrest 150 is fixed and can be moved forward and backward by being slide-coupled with the seat 110; A scaffold pulley (172) fixed to the scaffold (150); Vertical pulleys (174a, 174b) located on the vertical column (140); A support sheave 176 located on the support 130; And a rope 180 that is fixed at both ends to the vertical pole 140 and sequentially connects the scaffold sheave 172, the vertical sheave 174a, 174b, and the support sheave 176.

Preferably, a protrusion 210 protrudes from the footrest 150 to the side; And it may further include a guide portion 220 having a 'ㄷ' shape, fixed to the seat 110, and having a groove 222 through which the protrusion 210 can move.

A swing that moves using a pulley according to an embodiment of the present invention uses a footrest and a pulley so that the user can easily move the swing with little effort.

Figure 2a is a perspective view illustrating a swing that moves using a pulley according to another embodiment of the present invention, and Figure 2b is a side view.

Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the attached drawings.

Figure 1a is a perspective view illustrating a swing that moves using a pulley according to an embodiment of the present invention.

Referring to Figure 1a, the swing 100 that moves using a pulley according to an embodiment of the present invention includes a seat 110, a crossbar 120, a support 130, a vertical bar 140, a footrest 150, and a slide ( 160), a foot sheave 172, a longitudinal sheave 174a, 174b, a support sheave 176, and a rope 180.

The pedestal 110 is a place where the user sits and may further include a separate chair 112 at the top.

The crossbar 120 is a component on which the swing hangs, and is generally extended horizontally at the top of the pedestal 110.

The support bar 130 is erected vertically on the ground and serves to support the cross bar 120.

The vertical bar 140 is connected to the pedestal 110 and can swing back and forth while hanging on the crossbar 120 through a structure such as an axial coupling.

The footrest 150 can be pushed by the user. It can be positioned at the front end of the seat 110 and pushed with the foot, or it can be positioned at a height similar to the user's chest and pushed with the hand.

The slide 160 is fixed by being connected to the footrest 150 and can be moved back and forth by being slide-combined with the seat 110. When the user pushes the footrest 150 forward, the slide moves forward.

The sheave may be composed of a scaffold sheave 172 fixed to the scaffold 150, a vertical sheave 174a, 174b located on the stile 140, and a support sheave 176 located on the support 130. The rope 180 is sequentially connected in the following order: (172) → vertical sheave (174a, 174b) → support sheave (176) to move the swing. However, it is possible to operate only one vertical pulley, but as shown in Figure 1a, it is also possible to operate two vertical pulleys as an upper vertical pulley (174b) and a lower vertical pulley (174a).

Figure 1b is a side view illustrating the operation method of a swing that moves using a pulley according to an embodiment of the present invention.

When the user sits on the seat 110 and pushes the footrest 150, the footpeg pulley 172 and slide 160 coupled with the footrest also move and pull the rope 180, and the vertical bar 140 and the crossbar 120 Due to the axial connection, the swing moves overall to the upper front. And when the user takes his or her foot off the footrest 150, the swing moves back again due to potential energy, and the footrest 150 and the slide 160 also move backward again. Through this process, the user can move the swing by himself.

Figure 2a is a perspective view showing a swing that moves using a pulley according to another embodiment of the present invention, and Figure 2b is a side view.

Referring to FIGS. 2A and 2B, a swing 100 that moves using a pulley according to another embodiment of the present invention includes a seat 110, a crossbar 120, a support 130, a vertical bar 140, a footrest 150, It includes a slide 160, a foot sheave 172, a stile sheave 174a, 174b, a support sheave 176, a rope 180, a protrusion 210, and a guide portion 220. Here, only the protrusion 210 and the guide portion 220 will be described, and descriptions of the remaining components described in FIG. 1A will be omitted. However, in this embodiment, the footrest 150 is coupled to the slide 160 so that it can rotate partially.

The protrusion 210 is configured to protrude from the footrest 150 to the side.

The guide part 220 has a wide 'ㄷ' shaped plate shape and is fixed to the seat 110. The groove 222 is recessed so that the protrusion 210 can move through it. When the protrusion 210 moves along the groove 222, the footrest 150 also moves according to the shape of the groove 222, and at this time, the user's ankle exercises. The manufacturer may arbitrarily form the shape of the groove 222 so that the user can exercise the ankle in a specific motion while moving the footrest 150. For example, when the footrest moves back and forth in the shape of the groove 222 shown in Figure 2b, the protrusion 210 moves up and down and the part on which the user's foot rests partially rotates to help the user's ankle movement.
