Description

Human body stretcher for chairs and beds {STRETCHING DEVICE FOR FURNITURE}

The present invention relates to a human body stretching device installed in the furniture body, such as chairs and beds.

Chairs and beds are one of the essential pieces of furniture for people's lives and are commonly used for people to sit or lie down and rest. However, when people sit or lie down for long periods of time, the spine on the back of a person is tired, resulting in discomfort or fatigue. Therefore, people generally try to stretch and activate the human body.

However, when people sit or lie in a chair, they cannot stretch their body significantly. Thus, people usually get up from chairs or beds and do light stretching exercises, which is inconvenient to exercise due to furniture such as chairs or beds.

In addition, although people can stimulate the spine of the back through light exercise (stretching), they do not have a clear effect on reducing spinal fatigue because the spine cannot be effectively recovered.

It is an object of the present invention to provide an apparatus for extending and contracting up and down in the backrest of a furniture body such as a chair and a bed to stretch the human body.

The furniture main body has a conduit and a coupling part in the operation direction of the human body stretching device, and the device is composed of a motor, an extension table, a handle and the like. The motor is mounted to the engaging portion of the furniture body, the expansion table is installed at a position corresponding to the back of the furniture body to operate in accordance with the operation of the motor. The upper part of the telescopic arm is connected with the handle through a connecting rod installed in the lower part of the handle, and the block portion of the upper part of the handle is connected to the upper part of the conduit.

Both sides of the handle is provided with a gripping portion which can be easily grasped by a person, and a control button is installed near the gripping portion to control the operation of the motor. When one of the control buttons is pressed, the motor is operated to move the telescopic stand, and the handle is moved upwards to gradually extend the back part of the human body holding the gripping portion, and when the other one of the control buttons is pressed, the motor rotates in the opposite direction and the handle Will perform the contracting operation.

1 and 2, the present invention is a human body stretching device 2 installed behind the furniture body 1, such as a chair, the connection portion 12 on the upper back 11 of the furniture body 1, such as a chair A coupling hole 141 is formed in the flange portion in the coupling portion 14 of the seat 13 below the conduit 121 in the coupling portion 12, and a pin is inserted into the coupling hole. Alternatively, the joint 211 and the motor 21 of the human body stretching device are mounted in a bolt-nut fastening manner.

The stand 16 is arrange | positioned at the side surface of the sheet | seat 13, and the support stand 161 is provided in the upper part of this stand. A tooth part 151 is provided at a lower part of the armrest 15 having one end coupled to the backrest 11 of the chair, and the tooth part is engaged with the support 161. By arbitrarily engaging one of the teeth of the teeth of the armrest 15 with the support, the user can easily sit or lie down by adjusting the angle of the backrest 11 connected to the armrest 15.

The human body stretching apparatus 2 is largely comprised of a motor 21, an expansion and contraction table 22, and a handle 23.

The motor 21 is mounted to the engaging portion 14 of the seat 13 of the furniture body 1 through the joint portion 211 installed at the lower portion thereof, and the expansion and contraction table 22 is moved as the motor 21 rotates. There is a stretch operation.

The stretch table 22 is mounted to the backrest 11 of the furniture body 1 in the vertical direction, and the upper portion of the stretch table 22 is connected to the connecting table 231 installed under the handle 23 through the coupling means 221. It is fixedly connected.

The connecting rod 231 installed vertically under the handle 23 is square to correspond to the shape of the conduit 121, and the connecting rod is inserted into the conduit 121 and coupled with the upper portion of the stretchable rod 22, thereby rotating. It doesn't work. The handle 23 is provided with a gripping portion 232 that can be held by a human hand on both sides thereof corresponding to the upper portion of the conduit 121. Control buttons 233 and 234 are installed near the gripping portion 232, and the forward and reverse directions of the motor 21 may be controlled by operating the control button connected to the motor 21 through a conductive wire.

Referring to FIGS. 3 to 5, the operation of the present invention will be described. A person sits in the furniture body 1 and lifts his arm to hold the grip portion 232 of the handle 23 by hand, and then the finger (preferably Thumb to rotate the motor 21 by pressing one of the control buttons 233 and 234.

When the motor 21 is rotated in the forward direction, the stretching table 22 is extended to move the handle 23 above the furniture body 1, thereby holding the grip portion 232 of the handle 23 by hand The effect of stretching the spine of the user can be seen. When the user presses the other one of the control buttons 233 and 234, the motor 21 is rotated in the opposite direction, so that the expansion and contraction table 22 is contracted, and the handle is moved downward to return to the original position.

Referring to FIG. 6 showing another use state of the embodiment of the present invention, the backrest 11 supports the teeth 151 and the support 161 of the stand 16 installed on the armrest 15 of the furniture body 1. When engaged so as to be rolled back relatively (for example, when engaged with the support at the teeth of the frontmost teeth of the teeth of the teeth), the user grasps the grip portion 232 of the handle 23 while the user is lying down and the control buttons 233, 234 ), The stretching operation of the handle 23 can be controlled. The present invention can be easily used both when sitting or lying down.

According to the present invention described above, when the user is sitting or lying on the furniture body for a long time, and the spine comes to feel tired or uncomfortable, the user can effectively stretch (stretch) the body through the human kidney device.
