It includes. 1, a lock type gas spring 130 is disclosed as an example of the first height adjustment member, and a free type gas spring 140 is disclosed as an example of the second height adjustment member. In addition, various types of hydraulic / pneumatic cylinders may be suitable as height adjusting members.

In detail, the base plate 110 forms the base of the rehabilitation mechanism 100 that can adjust the height. The base plate 110 may have one or more base extensions 111 protruding toward the rehabilitation rod 120. In addition, the base extension 111 may be formed with one or more graduations 112 for length measurement.

A pair of rehabilitation rods 120 formed in parallel with each other is formed in the shape of a long bar (bar). Rehabilitation rods 120 may have one or more rehabilitation rod extensions 121 protruding toward the base plate 110. The rehabilitation rod extension 121 may further include a control member 122 capable of pressing the open pin 137 of the lock type gas spring 130 to be described later.

Here, the base extension 111 and the rehabilitation rod extension 121 may be formed in a hollow cylinder shape, respectively. Although the diameter of the base extension 111 is formed smaller than the diameter of the rehabilitation rod extension 121, the base extension 111 is drawn into the rehabilitation rod extension 121, but vice versa. It would also be possible if.

A lock type gas spring 130 or a free type gas spring 140 is formed in the base extension part 111 and the rehabilitation rod extension part 121 to form a base plate 110. Rehabilitation rods 120 may be connected. Here, one end of the lock type gas spring 130 or the free type gas spring 140 is coupled to the base extension 111 side, and the other end of the gas spring 140 is a rehabilitation rod. It can be coupled to the extension (121) side.

The lock type gas spring 130 will be described in more detail with reference to FIGS. 2 and 4 as follows.

The lock type gas spring 130 includes a cylinder 131, a piston 132 relatively reciprocating up and down inside the cylinder 131, and a piston rod 133 on which the piston 132 is mounted. do. In addition, the lock type gas spring 130 includes a gas sealing part 136 that seals the upper end of the cylinder 131, and the inside of the cylinder 131 is maintained at a predetermined pressure by the gas sealing part 136. maintain.

Meanwhile,

gas chambers

134 and 135 having a predetermined length are formed in the cylinder 131 sealed by the gas sealing unit 136, and a gas such as nitrogen is injected into the

gas chambers

134 and 135. In addition, the

gas chambers

134 and 135 are divided into the upper chamber 134 and the lower chamber 135 by the piston 132. In addition, the volume of the upper chamber 134 and the lower chamber 135 is changed by the vertical reciprocating motion of the piston 132. Here, the upper chamber 134 and the lower chamber 135 is maintained at a pressure higher than atmospheric pressure.

In addition, the lock type gas spring 130 includes an open pin 137 inserted through the center of the piston 132. The open pin 137 is connected to an operation lever (not shown), and the open pin 137 is configured to descend when the operation lever is pushed up or raised. Meanwhile, a valve pin 139 is formed at the center of the piston 132 to open and close gas, and an orifice 138 is formed at one side of the piston 132.

The operation of such a lock type gas spring is as follows. When the user presses the control member 122 connected with the open pin 137, the open pin 137 is pressed. When the open pin 137 is pressed downward, the valve pin 139 in contact with the open pin 137 is lowered. And, when the valve pin 139 is lowered, the gas stored in the upper chamber 134 is moved to the orifice 138 along the side of the valve pin 139. The air moved to the orifice 138 is moved to the lower chamber 135. Then, the volume of the lower chamber 135 is larger than the volume of the upper chamber 134 so that the piston 132 is relatively raised. Then, when the user removes the force applied to the adjustment button 160, the movement of the gas no longer proceeds. Thus, the gas spring is fixed at the height desired by the user.

The free type gas spring 140 will be described in more detail with reference to FIGS. 3 and 5 as follows.

The free type gas spring 140 includes a cylinder 141, a piston 142 relatively reciprocating up and down inside the cylinder 141, and a piston rod 143 on which the piston 142 is mounted. do. In addition, the gas spring 140 includes a gas sealing part 146 sealing the upper end of the cylinder 141, and the inside of the cylinder 141 is maintained at a constant pressure by the gas sealing part 146.

Meanwhile, gas chambers 144 and 145 having a predetermined length are formed in the cylinder 141 sealed by the gas sealing part 146, and gas such as nitrogen is injected into the gas chambers 144 and 145. The gas chambers 144 and 145 are divided into the upper chamber 144 and the lower chamber 145 by the piston 142. In addition, the volume of the upper chamber 144 and the lower chamber 145 is changed by the up and down movement of the piston 142. Here, the upper chamber 144 and the lower chamber 145 is maintained at a pressure higher than atmospheric pressure.

In addition, oil is injected into the gas chambers 144 and 145 in addition to nitrogen. The oil is lubricated in the piston operation, but also performs a damping role according to the drawing. Here, the principle of damping is due to the fact that the oil has a certain viscosity and operates quickly when the gas passes through the orifice hole of the piston, but slows when the oil passes. At this time, the effect of damping is determined by the amount of oil, viscosity and hole and piston operation of the orifice.

Such a free type gas spring 140 is impossible to adjust the position at any point, and has a property of being always tensioned. Because the nitrogen gas of high pressure is enclosed in the cylinder 141, and this nitrogen gas pressurizes the piston rod 143, the piston rod 143 always receives a repulsive force in an extension direction.

Hereinafter, the overall operation of the rehabilitation mechanism 100 capable of adjusting the height according to the first embodiment of the present invention will be described.

When the user presses the control member 122 capable of pressing the open pin 137 of the gas spring 130 in the state as shown in FIG. 1, and does not apply any force to the rehabilitation rod 120, the open pin 137. This is pressed and consequently the piston 132 rises relatively, thus increasing the overall length of the lock type gas spring 130. Then, as the overall length of the gas spring 130 is increased, the gas spring 130 pushes the rehabilitation rod 120 connected thereto, thereby raising the rehabilitation rod 120. Then, when the user removes the force applied to the control member 122, the movement of the gas no longer proceeds. Thus, the gas spring is fixed at the height desired by the user.

On the contrary, when the user presses the control member 122 that can press the open pin 137 of the gas spring 130 in the state as shown in FIG. 1, and presses the rehabilitation rod 120 downward, the open pin 137 is pressed and consequently the piston 132 is relatively lowered, thus reducing the overall length of the lock type gas spring 130. Then, as the overall length of the gas spring 130 is reduced, the gas spring 130 pulls down the rehabilitation rod 120 connected thereto, so that the rehabilitation rod 120 is lowered. Then, when the user removes the force applied to the control member 122, the movement of the gas no longer proceeds. Thus, the gas spring is fixed at the height desired by the user.

In this way, by dropping the
