On the bottom side of the seat plate and the middle plate, a hanging piece and a horizontal piece extending horizontally from the lower part of the hanging piece are provided. And an upper restricting member having a substantially L-shape, and on the top surface side of the middle plate and the bottom plate, an upright piece and a horizontal portion from the top of the upright piece The horizontal restricting member has a lower restricting member that has a substantially inverted L shape from the horizontal piece. The horizontal piece is formed long in the same direction as the guide groove, and the upper restricting member and the lower restricting member include the seat plate and the middle restricting member. A position that is attached to each of the plate and the bottom plate via an elastic member, and extends to a position where the hanging piece of the upper restricting member and the standing piece of the lower restricting member overlap each other with a space left and right, and the horizontal pieces can be engaged with each other The auxiliary spheres are slidable with the auxiliary spheres interposed between the horizontal pieces, and the auxiliary spheres are urged by the elastic members in the direction in which the upper restricting member and the lower restricting member are separated vertically. It is characterized by being always slidably contacted.

The invention according to claim 2 of the present invention includes a seat plate, an intermediate plate, and a bottom plate that are three-tiered vertically, and the seat plate and the intermediate plate have an upper support on the bottom surface side, and the intermediate plate and the bottom plate. Has a lower support at a position facing the upper support on the top surface side, and the upper support and the lower support between the seat plate and the middle plate extend in either the front-rear direction or the left-right direction. The guide groove is provided, and the support body and the lower support body between the middle plate and the seat plate are provided with a guide groove extending in a direction orthogonal to the upper support body and the lower support body between the seat plate and the middle plate. A sphere is interposed between them, and is freely slidable.An upper restricting member is provided on the bottom surface side of the seat plate and the intermediate plate, and a lower restricting member is provided on the top surface side of the intermediate plate and the bottom plate. The upper regulating member has a hanging piece, and the lower regulating member has an upright piece, and the hanging piece of the upper regulating member and the upstanding piece of the lower regulating member are It extends to the position where it overlaps with a gap on the left and right, one of the hanging piece and the standing piece has a horizontal piece that is long in the same direction as the guide groove, and the other has a roller that rotates the horizontal axis The horizontal piece is characterized in that the horizontal piece and the roller can be engaged with each other and are in a position spaced apart from each other in the vertical direction, and the roller can run along the horizontal piece.

  The invention according to claim 3 of the present invention has a biasing member between the seat plate, the middle plate and the bottom plate to return the sliding seat plate and middle plate to a position aligned with the bottom plate. Features.

  In the invention according to claim 4 of the present invention, the upper restricting member and the lower restricting member are such that the horizontal pieces of the upper restricting members and further the lower restricting members protrude outwardly, and protrude toward the upper side of the horizontal piece. A stopper having a locking member is provided on the upper surface of the middle plate and the bottom plate, respectively, and the locking member is urged in the protruding direction by the urging member.

  According to the first and second aspects of the present invention, when the seat plate and the middle plate are in the initial position, the urging force that can be pulled lightly toward each plate by the elastic member is applied to the upper regulating member and the lower regulating member. By providing the member, the auxiliary sphere is slidably contacted between both horizontal pieces. In addition, when the user swings his / her upper / lower / left / right side, if the top and bottom are three layers, the distance of the seat plate from the bottom plate becomes longer and the user's load slightly causes the seat plate and the middle plate to move slightly. Since the upper regulating member and the lower supporting member are attracted to the auxiliary sphere side due to the inclination, the auxiliary sphere slides smoothly without applying a strong pressure contact force from both horizontal pieces by extending and following the elastic member. As a result, the seat plate and the middle plate slide smoothly even when returning to the original position (center) where the seat plate and the seat plate are aligned vertically, so that various shakes combining the mutual movement of the seat plate and the middle plate are smoother. Therefore, even a user who has relatively little physical strength, such as an elderly person, a child, or a handicapped person, can obtain an exercise effect more easily.

  According to the second aspect of the present invention, when the user swings, when the seat plate and the middle plate return from the maximum swing position to the original position, the roller that rotates horizontally rotates both the upper and lower restricting portions. The seat plate and the middle plate can be smoothly slid in the same manner as the health chair according to claim 1 by rolling while abutting between the horizontal pieces.

  According to the third aspect of the present invention, the seat plate and the middle plate return to the initial position where the bottom plate overlaps with the bottom plate after the user swings by the biasing member, so that the user's body is to be pulled back. Strength works to further enhance the exercise effect. In addition, it is easy for the next user to use, and design properties when not in use are also maintained.

  According to the invention described in claim 4 of the present invention, the locking member, the horizontal piece, and the horizontal piece are obtained by pulling out the locking member of the stopper to the outside of the seat plate, the middle plate, and the bottom plate against the biasing force of the biasing member. Is released, and if you release your finger from the locking member, it will return to its original position, so you can easily remove the middle plate from the bottom plate, and even the seat plate from the middle plate, like the elderly and infants Even those who are relatively weak can easily carry this health chair.

  A specific configuration of the health chair of the present invention will be described below based on the drawings.

  As shown in FIG. 1 (a), this health chair has a seat plate 1, a middle plate 2 and a bottom plate 3 on which a user sits, and is stacked in three stages up and down. The middle plate 2 is slidable in the left-right direction on the top surface side of the bottom plate 3.

Furthermore, the sliding of the middle plate 2 and the bottom plate 3 and the seat plate 1 and the middle plate 2 when the user sits on the health chair will be described.
First, between the seat plate 1 and the middle plate 2, as shown in FIG. 1 (b), a block-shaped upper support body 5 extending left and right is provided on the bottom surface side of the seat plate 1. In the part corresponding to the upper support 5, a lower support 6 having a block shape is provided. And the guide groove | channels 7 and 7 of a cross-sectional groove shape are provided in the lower end surface side of the lower support body 6a, and the upper end surface side of the upper support body 5, respectively, and also the spherical body 9 is between each guide groove 7 and 7. FIG. By interposing and rolling the spherical body 9, the seat plate 1 can slide in the left-right direction from the intermediate plate 2 when the collar portion H is placed. Further, the longitudinal ends of the upper support 5 and the lower support 6 are connected by a rubber belt 14, whereby the belt 14 allows a gap between the upper and lower supports 5, 6 to pass through the health chair. Therefore, when the seat plate 1 and the middle plate 2 are slid, it is possible to avoid the risk of pinching the fingers between the upper and lower supports 5 and 6.

As shown in FIGS. 2 (a) and 2 (b), the upper and lower supports 5 and 6 are disposed on the lower end surfaces of the seat plate 1 and the middle plate 2 with cushion members 13a and 13b interposed therebetween. The lower regulating members 11 are provided on the upper end surfaces of the middle plate 2 and the bottom plate 3, and the upper regulating member 10 is suspended substantially vertically from the lower end surfaces of the seat plate 1 and the middle plate 2. The hanging piece 10a and the horizontal piece 10b projecting in the substantially horizontal direction from the lower end of the hanging piece 10a form a substantially L shape. Next, the lower restricting members 11 and 11 are substantially formed from a standing piece 11a that stands substantially vertically from the upper end surfaces of the middle plate 2 and the bottom plate 3, and a horizontal piece 11b that protrudes substantially horizontally from the upper end of the standing piece 11a. Inverted L-shaped.
The upper restricting member 10 and the lower restricting member 11 are disposed at positions opposite to each other in the vertical direction of the lower end surface of the seat plate 1 and the upper end surface of the intermediate plate 2 and the lower end surface of the intermediate plate 2 and the upper end surface of the bottom plate 3. The horizontal pieces 10b and 11b are arranged at positions where the horizontal pieces 10b and 11b are stretched in the vertical direction, and a relatively hard resin auxiliary sphere 12 made of nylon resin is in contact between the horizontal pieces 10b and 11b. . Reference numeral 9a is a ball stop.

When formed as described above, when the user sits on the seat plate 1 and rocks, the seat plate 1 and the middle plate 2 are arranged between the upper and lower supports 5 and 6 interposed between the seat plate 1 and the middle plate 2. The seat plate 1 slides in the front-rear direction with the intermediate plate 2 as a base point with the sphere 9 therebetween. Further, the intermediate plate 2 and the bottom plate 3 slide in the left-right direction with the base plate 3 as a base point with the sphere 9 between the upper and lower supports 5 and 6 interposed between the intermediate plate 2 and the bottom plate 3 interposed therebetween. . As a result, the seat plate 1 swings in the front-rear direction of the middle plate 2 and the middle plate 2 swings in the left-right direction of the bottom plate 3. For example, as shown in FIGS. The board 1 can be swung in a variety of patterns that are combined in the front-rear and left-right directions.
When the seat plate 1 and the middle plate 2 are at the maximum slid position, as shown in FIGS. 2C and 2D, the auxiliary sphere 12 positioned between the upper restricting member 10 and the lower restricting member 11 is provided. By sliding freely in contact with the horizontal pieces 10b, 11b, even if the seat plate 1 is tilted by the load of the user and lifted from the intermediate plate 2, the auxiliary sphere 12 is interposed, thereby the seat plate 1 can be rocked without rattling.

  Further, a rubber cord 17 is stretched between the seat plate 1 and the middle plate 2 and between the middle plate 2 and the bottom plate 3, and one end of each of the rubber cords 17 and 17 is below the seat plate 1 and the middle plate 2. Lower supports 6, 6 fixed between two upper supports 5, 5 attached to the end face, and having the other ends of the rubber strings 17, 17 attached to the upper ends of the middle plate 2 and the bottom plate 3, respectively. It is fixed between. As a result, when the user stands up after sitting on the seat board 1 and swinging, the seat board 1 and the middle board 2 return to the original position by the urging force of the rubber cord 17, and the health chair is in a state before use, that is, The seat plate 1, the middle plate 2, and the bottom plate 3 overlap each other.

  Further, the basic configuration between the middle plate 2 and the bottom plate 3 is substantially the same as that between the seat plate 1 and the middle plate 2 described above. 6 and the upper and lower restricting members 10 and 11 are extending in the direction in which the groove directions of the guide grooves are orthogonal. 6A to 6D, the seat plate 1 swings in the front-rear direction of the intermediate plate 2 and the intermediate plate 2 swings in the left-right direction of the bottom plate 3, so that sliding A variety of movements depending on the combination of directions gives the user an efficient massage effect while sitting.

FIGS. 3A to 3D show another embodiment of the health chair of the present invention, and only the configuration different from the above embodiment will be described.

The upper restricting member 10 is arranged in a state where a clearance is provided with a slight gap from the upper end surface side of the horizontal piece 10b. In this way, as shown in FIGS. 3C and 3D, when the seat plate 1 and the middle plate 2 slide to the maximum position with the bottom plate 3 as the base point, the seat plate 1 and the middle plate 2 slide. Since the anti-sliding direction side is lifted when the direction side is lowered by the load, the roller 18 comes into contact with the upper end surface side of the horizontal piece 10b, rotates and travels following the sliding of the seat plate 1 and the intermediate plate 2. .
Further, in this embodiment, a film 19 having a smooth surface on one side is attached to a portion that contacts the roller 18 on the upper end surface of the horizontal piece 10b, and the resistance when the roller 18 travels can be made as small as possible. It is possible to reduce the collision sound when 18 is in contact.

Further, the health chair according to the present embodiment is provided with a stopper 16, and the stopper 16 is provided on the upper end surfaces of the intermediate plate 2 and the bottom plate 3 as shown in FIGS. 4 (a) and 4 (b).
