Description

  The present invention relates to a swing seat chair that can swing a seat portion back and forth around a rear end portion of a seat portion on which a user is seated, and more specifically, for example, a user's legs and hips at rest. The present invention relates to a swing seat chair capable of preventing economy syndrome by swinging a seat portion and a back plate portion by bending and stretching and performing strength training such as abdominal muscles.

  As a conventional swing seat chair, a rocking chair is widely known. A rocking chair usually has an elongated bow-shaped curved plate attached to the lower ends of a pair of left and right legs, and the rocking chair swings back and forth through the curved plate as the user's center of gravity moves. . Therefore, when the user sits on the rocking chair, the rocking chair swings back and forth through the curved plate, and a relaxing time can be spent. Patent Documents 1 and 2 disclose chairs having a function similar to a rocking chair using a spring.

  Patent Document 1 discloses a rocking chair having a training function. The rocking chair is attached to the upper surface of a fixed board having leg legs fixed on both sides and has the same shape as the fixed board, and is attached to both sides of the rotary board and is configured to be movable forward and backward. A pair of left and right leg rests, a pair of left and right leg rests connected to the ends of the pair of leg rests via an angle adjusting ratchet mechanism, and the pair of leg rests. An adjustable footrest plate, a frame body provided on the upper surface of the rotating board, a seat with a required backrest attached to the upper surface of the frame body, and this frame body in all directions of east, west, south, and north A coil spring that is supported in a swingable manner, and the user can sit down and perform rodeo exercises through the coil spring to improve physical fitness and blood circulation, so that the ankle, knee, waist, etc. Muscle strength Can the sake of (paragraph [0010], [0011]) is a. Therefore, this rocking chair was developed mainly for training as the name of the invention shows.

  Patent Document 2 discloses a swinging chair that swings like a rocking chair. The swing chair includes a seat portion, a receiving portion that receives the seat portion, a convex portion provided on one of the seat portion and the receiving portion, and a seat portion that is evenly arranged in the front, rear, left, and right around the convex portion. And an elastic body that connects the receiving portion, and the seat portion swings in that direction when the upper body is tilted in either direction while the user is sitting. This swinging chair swings smoothly in either direction, so there is no burden on the user's buttocks and lower back, and comfort can be obtained, and at the same time, body movement and weight compression can be reduced to reduce congestion and back pain. It is said that it is effective in prevention ([Effect] on page 1).

  However, in the rocking chair described in Patent Document 1, since the coil spring is self-supporting, when the user sits on the rocking chair, the seat body and the backrest move in either direction due to the movement of the center of gravity of the body on the seat body. It swings and the seating posture is unstable. In addition, this rocking chair has a footrest heel and a footrest heel connected via an angle-adjusting ratchet mechanism so that the body can bend and stretch by placing a foot on a footrest plate built for the footrest for training purposes. Therefore, the structure of the rocking chair itself is complicated and tends to be expensive in cost. The swing chair described in Patent Document 2 is simpler in structure than the rocking chair described in Patent Document 1, and thus is less expensive than the rocking chair described in Patent Document 1. Since the portion and the receiving portion are connected by a plurality of elastic bodies arranged symmetrically in the front, rear, left and right around the convex portion, the elastic bodies arranged symmetrically with each other, regardless of the direction in which the seat is inclined, Since the elasticity acts in the direction of canceling out the elasticity of the muscles, the elasticity during the strength training of the abdominal muscles and the like cannot be expected so much, and the seat portion is in any direction as in the rocking chair described in Patent Document 1. However, there is a problem that the posture is not stable because it swings.

  The present invention has been made to solve the above-mentioned problems, and can be manufactured at a low cost with a very simple structure. Also, when a user, particularly an elderly person, sits for a long time and relaxes, the left and right are Legs and hips can bend and stretch in a stable posture without sticking, economy syndrome can be prevented by bending and stretching the legs, and strength training such as abdominal muscles can be performed and flexion of the hips can be developed An object of the present invention is to provide a rocking chair that can be used.

The swing seat chair according to claim 1 of the present invention includes a seat portion, a back plate portion connected to a rear end portion of the seat portion, and a support body that supports the seat portion and the back plate portion. A pair of elongate first bundles arranged and fixed vertically on both left and right side surfaces of the rear end of the seat, and a pair of left and right armrests fixed to the upper ends of the pair of first bundles, respectively. The pair of first bundles are slidably connected to the left and right sides of the support body, and the seat portion and the back are arranged with the rear end side of the seat portion as an axis through the pair of first bundles. A swing seat chair having a support shaft that supports the plate portion and the armrest portion so that the plate portion and the armrest portion can swing back and forth on the support body, and a second bundle that is bent downward is formed in front of the armrest portion.

It is principal part sectional drawing which shows these. It is a conceptual diagram which shows the side surface of the state which uses the rocking | fluctuation seat chair shown in FIG.

Hereinafter, an embodiment of the swing seat chair of the present invention will be described with reference to FIGS.
For example, as shown in FIGS. 1 and 2, the swing seat chair 10 of this embodiment includes a seat portion 11 on which a user sits, and a back plate portion 12 having a lower end portion connected to a rear end portion of the seat portion 11. And a rectangular support 13 that supports the seat 11 and the back plate 12 and a left and right side surface of the rear end of the seat 11 connected to each other via a fixture (for example, a screw member) 14 in the vertical direction. The pair of fixed first elongated bundles 15 (see FIG. 4B), the pair of left and right armrests 16 fixed to the upper ends of the pair of first bundles 15, respectively, and the pair of first bundles 15 is slidably connected to the left and right side surfaces of the support 13, and the seat 11, the back plate 12 and the armrest 16 are connected to the seat 11 via the pair of first bundles 15. And a support shaft 17 (see FIG. 4B) that swings back and forth around the rear end portion. Further, a second bundle 16A bent downward as shown in FIGS. 1 to 3 is provided in front of the armrest portion 16, and the side shapes of the armrest portion 16 and the second bundle 16A are formed in an approximately L shape. ing.

  As shown in FIG. 1, FIG. 2 and FIG. 4 (a), the support 13 is formed as a rectangular surface whose front surface is perpendicular to the floor surface and whose back surface forms an acute angle with the floor surface. Is formed. The bottom surface of the support body 13 is deeper than the top surface, and the seat portion 11 and the back plate portion 12 are stabilized against swinging in the front-rear direction by stably supporting the seat portion 11 and the like. A pair of first elastic bodies 18 that impart elasticity to the front end portion of the seat portion 11 are provided on the left and right sides of the front end portion of the upper surface of the support body 13. As shown in FIG. 4A, the first elastic body 18 has a coil spring 18A and a columnar rubber 18B fitted into the upper end of the coil spring 18A. The rubber 18B has a height that does not significantly affect the elasticity of the coil spring 18A. As shown in FIG. 4A, the lower end of the coil spring 18A is fixed to the upper surface of the support 13 through a fastener 18C. The elastic body 18 is in contact with the lower surface of the seat portion 11 by the rubber 18B, elastically lifts the front end portion of the seat portion 11 from the support body 13, and the front end portion of the seat portion 11 is lifted from the rear end portion and inclined. It is in a state. The elasticity of the first elastic body 18 can be adjusted by appropriately selecting the magnitude of the elasticity of the coil spring 18A as necessary. Needless to say, the first elastic body 1 may be one in which the rubber 18B is omitted.

  As another elastic body 18, for example, a guide rod hanging from the lower surface of the seat portion 11 is provided inside the coil spring 18 A, and a hole through which the guide rod passes is provided on the upper surface of the support body 13. The coil spring 18 </ b> A may expand and contract between the seat 11 and the support body 13 along with the swing, and the guide rod may move up and down the hole of the support body 13. In this way, the coil spring 18A can be stably expanded and contracted according to the support rod. The first elastic body 18 is not limited to the above-described one, and a material having elasticity such as an air spring can be widely used. Moreover, although the case where the 1st elastic body 18 was each provided in the upper surface of the support body 13 on either side was demonstrated, you may provide only one in the width direction center of the support body 13, and the width direction A plurality of them may be provided. The elasticity acting between the seat portion 11 and the support body 13 can also be set by appropriately adjusting the number of the first elastic bodies 18 as necessary.

  Moreover, as shown in each figure, the 2nd elastic body 19 interposed between a floor surface is also provided in the lower end surface of the 1st bundle | flux 16A on either side, respectively. The second elastic body 19 is configured according to the first elastic body 18. Therefore, when the user sits on the swing seat chair 10 and bends forward, the seat 11 swings forward against the elasticity of the first and second elastic bodies 18 and 19, so The muscle strength is trained by the elasticity of the first and second elastic bodies 18 and 19.

  The first elastic body 18 and the second elastic body 19 are more preferable for strength training of the legs and hips as the elasticity is stronger. However, if at least one of these elastic bodies 18 and 19 is present, the required strength training can be performed. it can. Since the first and second elastic bodies 18 and 19 can appropriately set the elasticity as necessary, the necessary elasticity can be achieved by at least one of the elastic bodies 18 and 19. If the elastic body is one of the first and second elastic bodies 18 and 19, the elastic bodies 18 and 19 tend to be enlarged depending on the elasticity. In this case, the first and second elastic bodies 18 and 19 can share elasticity.

  Moreover, the 1st bundle 15 and the 2nd bundle 16A are connected through the elongate connection board 20 by each lower end, as shown in FIGS. 1-3. The connecting plate 20 is formed as a straight horizontal plate, and the rear end protrudes rearward of the first bundle 15. Reinforcing plates 21 are provided at the rear end of the armrest 16 and the rear end of the connecting plate 20 so as to be inclined with respect to the connecting plate 20. The reinforcing plate 21 serves as a reinforcing member when the swing seat 10 swings rearward and the rear end of the connecting plate 20 contacts the floor surface. An elastic member (for example, rubber) 22 is attached to the lower surface of the rear end portion of the connecting plate 20.

  As described above, the swing seat 10 of the present embodiment swings only in one direction in the front-rear direction, and thus repeats stable swinging in one direction. The user can get a sense of balance against swinging, and the user can feel relaxed and relaxed with a stable posture.

  Thus, a conventionally known tilt angle adjusting mechanism (not shown) is provided between the rear end of the seat portion 11 and the lower end of the back plate portion 12, and the seat is interposed via the tilt angle adjusting mechanism. The inclination angle between the portion 11 and the back plate portion 12 is appropriately adjusted. Moreover, the inside of the seat part 11 and the back plate part 12 is formed by a cushion material such as a spring or foamed urethane, and the user's buttocks and back are curved and formed so as to fit the seat part 11 and the back plate part 12. ing.

  The support body 13 is formed in a trapezoid shape whose back surface is inclined as described above. In the present embodiment, the support body 13 is formed as a storage box for storing small items. The support 13 includes a housing 13A and a drawer 13B that can be taken in and out of the housing 13A via a slide mechanism (not shown). The support 13 can be formed of wood such as plastic or plywood. Accordingly, the support 13 can be used as a storage box for storing small items such as personal items. Further, the support 13 is not necessarily formed in a box shape, and may be formed as a frame, for example.

  As shown in FIG. 4B, a pair of first bundles 15 are connected and fixed to the left and right side surfaces of the rear end portion of the seat portion 11 via two screws 14 on the upper and lower sides. 15 is attached to the support 13 via a support shaft 17 so as to be swingable. The support shaft 17 connects the first bundle 15 in a swingable manner to the side surface of the support 13 via a nut 17A. For example, a pair of left and right projections 11A are formed in a spherical shape at the rear end of the lower surface of the seat portion 11, and the seat portion 11 is in point contact with the upper surface of the support 13 via the pair of left and right projections 11A. Further, as shown in FIG. 4B, the front end of the seat 11 is levitated at the front front end of the support 13 via the pair of left and right first elastic bodies 18 and is elastically supported.

  Next, the case where the rocking | swivel seat chair 10 of this embodiment is used is demonstrated. When the user sits on the seat portion 11 of the swing seat chair 10 and sits down deeply on the swing seat chair 10, the buttocks and the back are placed in the seat portion 11 and the back plate portion 12, respectively, as shown in FIG. You can relax slowly for a long time by putting both feet on the floor and standing still.

  At this time, when you use your feet to stretch or shrink your back, push the floor with both feet, tilt your back backwards and stretch your legs, then apply the force to pull the floor with both feet and thighs When a force is applied to the front end portion of the seat portion 11 against the elasticity of the first and second elastic bodies 18 and 19, the seat portion 11 swings clockwise as indicated by an arrow in FIG. The second elastic bodies 18 and 19 are most compressed. At this time, repulsive forces from the first and second elastic bodies 18 and 19 act on the abdominal muscles and thigh muscles. Subsequently, when the floor surface is pushed with both feet and the body is stretched and the force of the thighs is released and the body is tilted backward, the first and second elastic bodies 18 and 19 are swung counterclockwise by the repulsive force. The back and abdominal muscles relax by moving.

  In this manner, the abdominal muscles, back muscles and leg muscles can be stretched and trained to train each muscle strength by bending the body back and forth using the legs and waists while the user is sitting on the rocking chair 10. In addition, such a back-and-forth bending and stretching movement provides a sense of balance and can prevent economy syndrome due to promoting blood flow in the legs. In particular, elderly people often sit down for a long time and tend to be short of exercise, but by using their legs to bend and stretch while sitting on the rocking chair 10, the muscle strength of the legs and hips is stimulated. Thus, it is possible to reinforce the decline in muscle strength and to prevent economy syndrome due to prolonged sitting. In addition, the user can maintain a sense of balance by swinging in one direction only in the front-rear direction of the swing seat 10.

  As described above, according to this embodiment, the first and second elastic bodies 18 and 19 are provided between the seat portion 11 of the swing seat 10 and the support body 13 and at the lower ends of the pair of left and right second bundles 16A. Since each of them is provided, the structure of the rocking chair 10 is extremely simple and can be manufactured at low cost, and in the case of a user, particularly an elderly person, when the user sits for a long time, the swinging chair 10 is left and right. Legs and hips can be bent and stretched in a stable posture without sticking, and muscle training such as abdominal muscles is performed in order to bend and stretch the legs and hips against the elasticity of the first and second elastic bodies 18 and 19 while sitting. In addition, the bending and stretching of the leg can promote the blood flow of the leg and prevent the economy syndrome.

  In addition, this invention is not restrict | limited at all to the said embodiment, Each component can be changed in design suitably as needed.
