[0007]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention comprises a seat plate part supported by legs at a constant height and a back support part, and the back support part is bent in an arc shape from the upper part toward the rear side, and the seat plate part is formed. There is provided a back stretching chair having a structure in which a locking part for locking the front part of the user's ankle is provided below the front part of the backrest.

[0008]

[Action]

 Since the present invention has the above-mentioned configuration, when the ankle is locked to the rear part of the locking part, the waist is placed on the seat plate, the back is pressed against the back support part, and the back is extended along the back support part. Even hard people can extend their legs sufficiently without lifting their legs.

【Example】

 In the first embodiment shown in FIGS. 1 to 3, 11 is a pair of left and right leg frames formed from a pipe or the like. This leg frame 11 is similarly connected by connecting left and right connecting frames 12 such as pipes, and a plurality of horizontal bars 13 made of wood or the like are arranged side by side on both leg frames 11, and both ends thereof are fixed. To form the seat plate 14.

Left and right back support frames 15 made of pipes and the like are provided at the upper rear ends of the two leg frames 11, and a plurality of horizontal bars 16 made of wood or the like are arranged in parallel at the front part thereof, and both ends thereof are fixed. Then, the back receiving portion 17 curved in an arc shape is formed rearward. Then, on the front portions of the left and right leg frames 11, a horizontal rod-shaped locking portion 18 made of a round pipe or the like is fixed at an appropriate height.

In the chair 19 described in the first embodiment, as shown in FIG. 3, the ankle 21 of the user 20 is locked to the rear portion of the locking portion 18, the waist is placed on the seat plate 14, and the back is held. By pressing it against the back support portion 17 and extending the back along the back support portion 17, even a person with a firm body can fully extend the body without lifting the legs.

In the chair 22 of the second embodiment shown in FIG. 4, the seat plate 24 is mounted on the left and right leg frames 25 in a floating manner by a plurality of springs 26, and the back support portion 27 is attached to the back portions of the rear portions of the both leg frames 25. A plurality of springs 29 are attached to the receiving frame 28 in a floating manner.

Then, vibrators 30 and 31 using an electric motor, an electromagnet or the like are fixed to the back surfaces of the seat plate 24 and the back receiving portion 27 to vibrate the seat plate 24 and the back receiving portion 27. Further, a horizontal bar-shaped locking portion 32 made of a round pipe or the like is fixed to the front portions of the left and right leg frames 25 at an appropriate height.

Also in the chair 22 according to the second embodiment, as in FIG. 3, the user's ankle is locked to the rear part of the locking part 32, the waist is placed on the seat plate 24, and the back is supported by the back support part 27. When the back plate 27 and the back support part 27 are vibrated by the vibrators 30 and 31, the back plate 27 and the back support part 27 are vibrated by the vibrators 30 and 31. It can be stretched, and vibration can relieve fatigue by relieving stiffness in the entire body.

In the first embodiment, the seat plate 14 and the back receiving portion 17 are shown to be composed of a plurality of horizontal bars, but this is only an example, and in addition, a plastic like the second embodiment is used. It is possible to use all the materials that are normally used for chairs, such as formed products such as boards, wood boards, and boards with cushions placed on cloth and leather.

[0016]

[Effect of device]
