In addition, according to the present invention, since the chair provided with the hanging portion is foldable, the chair can be compactly stored when not in use.

Hereinafter, the basic configuration of the present invention will be described with reference to FIGS. 1 and 2, taking a wooden chair as an example.

FIG. 1 is a perspective view, and FIG. 2 is a side view depicting a side view of the usage state.
1 and 2, reference numeral 1 denotes a rear leg. In the rear leg 1, a pair of left and right legs 11, 12 are formed in parallel and integrally using a linear member, and are linear in a side view as shown in FIG. Here, the term “linear” means not only a correct straight line but also a state extending substantially linearly.

The rear leg portion 1 has a hanging portion 2 at a height position where both hands can reach when a person sits on a seat portion which can be described later, in this example, a height position where both hands reach above the head. doing.
The hanging portion 2 is a horizontal member that can be gripped by a hand between upper ends of the upper and lower ends of a pair of parallel left and right leg portions 11 and 12 that are integrally formed. The entire rear leg 1 is formed into a U-shape with the hanging part 2 and the pair of left and right legs 11, 12.

Reference numeral 3 denotes a front leg portion. A pair of parallel left and right leg portions 31 and 32, which are integrally formed, are also formed in parallel and integrally using a linear member, as shown in FIG. Become.
In the front leg portion 3 shown in this embodiment, a backrest portion 4 is horizontally arranged so as to be spanned between the upper end portions of a pair of left and right leg portions 31, 32, as can be seen from the perspective view of FIG. The back portion 2 and the pair of left and right legs 31 and 32 have the entire front leg 1 turned down, and the U-shape is integrated by connecting the lower ends of the legs 31 and 32 in series. Further, in this case, if the backrest portion 4 is provided as described above, the front leg portion 3 has a square shape (not shown).

The front leg portion 3 configured as described above is pivotally mounted between the left and right leg portions 11 and 12 of the rear rear leg portion 1 via the rotation shaft 33 so that the upper end side of the front leg portion 3 is rotatable. In addition, the thickness in the front-rear direction of the front leg portion 3 and the thickness in the front-rear direction of the rear leg portion 1 are overlapped in a side view.
As described above, at least the thickness in the front-rear direction of the front leg 3 and the thickness in the front-rear direction of the rear leg 1 are formed so as to overlap at least partially in side view, that is, not used. It is possible to reduce the overall thickness of the front leg portion 3 and the rear leg portion 1 in the front-rear direction at the time, and it is possible to realize compactness during storage.

The illustrated front leg portion 3 has a length from the pivot shaft 33 to the lower end, ie, the ground contact end (hereinafter also referred to as the leg length of the front leg portion 3), and the length from the pivot shaft 33 of the rear leg portion 1 to the lower end, ie, the ground contact end. It is formed longer (hereinafter also referred to as the leg length of the rear leg 1), and is configured such that the rear leg 1 is in a vertical state when used as a chair.
However, the present invention is not limited to this, and when the rear leg 1 is set in a vertical state (the vertical state is not limited to an accurate vertical but includes a substantially vertical state, that is, a so-called standing state), You may comprise the leg length of the front leg part 3 shorter than the leg length of the rear leg part 1 so that a lower end may become the length which does not contact | connect, ie, the length which leaves | separates from a contact surface. With this configuration, the side view of the rear leg portion 1 and the front leg portion 3 is a “person” shape when used as a chair, but the lower end (grounding end) of the rear leg portion 1 is grounded. By tilting the rear leg portion 1 forward, it is possible to swing it out by moving the hand to the front side, preferably naturally or lightly.

Reference numeral 5 denotes a leg opening degree regulating means for defining a maximum leg opening limit between the front leg portion 3 and the rear leg portion 1, and a leg between the left leg 31 of the front leg portion 3 and the left leg 11 of the rear leg portion 1. And between the right leg 32 of the front leg 3 and the right leg 12 of the rear leg 1. As the leg opening degree restricting means, an appropriate cord band having a predetermined length with both end sides fixed to the material leg portion (not shown) may be used, and one end side of the long member may be rotated with one leg. It is also possible to use means (not shown) that is movable and that engages and disengages the engaging recess on the other end side with the other locking projection.

  Reference numeral 6 denotes a seat. The seat portion 6 is linear in the front-rear direction in a side view, and in this embodiment, the thickness thereof is equal to or at least smaller than the thickness of the front leg portion 3 in the front-rear direction. A pivot shaft 61 is pivotally mounted between the left and right legs 31 and 32 of the front leg portion 3. Since the seat portion 6 is supported on the front leg portion 6 only by the rotation shaft 61, it is necessary to sit in a balanced manner so that the position of the heel portion is kept balanced in the front-rear direction when seated.

  However, when the seat portion 3 is arranged so as to be rotatable in this way, when the user wants to extend the spine while sitting, the arm portion is placed on the seat surface with both hands raised and the hanging portion 2 held. If you move it forward while floating the buttocks in the manner of sliding, the seat part 3 will move forward without tilting without resistance. ) Can be easily performed in a state of dropping, and if the buttock is moved backward in the manner of sliding on the seat surface in the hanging state, the seat portion 3 returns to the horizontal state without resistance. The seated state can be returned to the sitting state.

In other words, according to the chair of this embodiment, it is possible to easily perform a hanging motion at any time while sitting down, for example, when feeling tired at any time during desk work, and work immediately. You can continue. In addition, the extension of the back muscles in the hanging state is much more effective than the back extension in which both hands are pushed out because the weight of most of the upper body is applied.

Further, since the seat portion 6 is formed to have a thickness equal to or at least smaller than the thickness of the front leg portion 3 in the front-rear direction, when the seat portion 6 and the front and rear leg portions 1, 3 are folded in a vertical state, Since the folding thickness overlaps with the rear leg 1, the storage space can be accommodated in the space of the rear leg 1 itself, and the compactness can be realized in the minimum space.
Further, since the seat portion 6 can be accommodated in the front leg portion 3 and the front leg portion 3 can be accommodated in the rear leg portion 1, it is convenient for transportation, storage or packaging.

Further, the seat portion 6 has a rotating shaft 61, that is, the front side of the seating portion 61 of the seat portion 6 is heavier than the rear side in the front-rear direction of the seat portion 6, and the front side hangs downward in a free state. By configuring the seat portion 6 so as to be in a vertical state, the seat portion 6 is always urged to rotate so that the front end side is positioned vertically downward. The seat can be easily and quickly seated simply by moving it backwards in the manner of sliding on the seating surface.

Also, when extending the spine while sitting on the hanging part 2, the seat part 6 tilts forward simply by lifting the buttocks from the seating surface. There is no need to make it.
Further, when the seat 6 is not seated, the seat 6 naturally becomes vertical, so that the front end of the seat 6 protruding forward in the horizontal state does not exist. Space can be reduced.

Further, when the chair itself is removed and stored, the rear leg 2 or the hanging part 2 is lifted lightly, or the rear leg 1 is tilted rearward while the rear leg 2 is installed. As a result, the seat portion 6 together with the front leg portion 3 is naturally brought into a vertical state, so that it is possible to easily perform even elderly people and powerless women without requiring a force for folding the chair.

As shown in the drawing, the seat portion 6 of this embodiment is substantially U-shaped from the rear side to the front side so that a rotational bias is always applied so that the front end side is positioned vertically downward. The rear portion of the seat portion 6 is reduced in weight by forming a notch portion 62, and an edge portion 63 is formed in the notch portion 62 in which the rear portion of the collar portion is fitted and caught in the state of sitting on the seat portion 6. Has been.
As described above, by providing the edge 63 to which a part of the collar is hooked, the user can be seated stably by appropriately selecting the position of the collar on the seating surface. Since the seat portion 6 can be easily rotated in any of the front and rear directions by the action of the buttocks using this, a hanging health chair with good operability can be provided without using a hand.

  In the above description, the front leg portion 3 and the seat portion 6 are both pivotally mounted in a freely rotating state. However, the present invention is not limited to this. You may keep it.

The hanging health chair according to the present invention can be used not only for home use, but also as a chair for office work or production work site, and can be easily seated at any time without any special space. Moreover, since the hanging exercise effective for health and relaxation can be performed, the fatigue of the body caused by sitting for a long time can be eliminated, and the productivity can be remarkably improved.
