Description

[Technical field]

[0001] This invention relates to a functional health chair that stimulates the acupressure points of traditional Chinese medicine and promotes health. [Background technology]

[0002] The basic function of a chair is to support the upper body of a seated person while resting and working. Chairs generally consist of a hip and lumbar support assembly, which may include springs, cushions or pads that rest on the springs. When using a chair, a seated person generally adopts two characteristic postures, including a lean-back resting posture and a lean-forward working posture.

[0003] A chair must be able to deform appropriately to accommodate these two specific postures that a seated person assumes, and support the body of the seated person. Many chairs have been introduced that can hold the upper body of a seated person in a comfortable and good posture during rest. Chairs are equipped with backrests, but most of these backrests are not adjustable, which can lead to fatigue when seated for long periods of time, and can cause problems such as pinched nerves in the lumbar vertebrae and spinal deformity. Therefore, research into functional chairs that can solve these problems is required.

[0004] A conventional chair seat body (1) has a seat portion (3) and a back portion (4), and a leg member (2) has a front leg (12) that is aligned with the seat portion (3) of the chair seat body (1) and a floor frame (13) that is aligned with the back portion (4). The front leg (12) of the leg member (2) is pivotally attached to the seat portion (3) by a pivot (15). This allows the leg member (2) to rotate between a folded position aligned with the chair seat body (1) and an unfolded position in which the front leg (12) stands upright below the seat portion (3) and the floor frame (13) stands along the floor surface. In the unfolded position, a rear leg (9) is pivotally attached (19) to the floor frame (13) so as to be positioned in an upright state. The tip of the rear leg (9) engages with an engagement portion (20) of the seat body (1) in the unfolded position. When the leg members are in the extended position, the chair becomes a chair with legs, and when they are in the folded position, the chair becomes a seat. This is disclosed in the following patent document. [Patent Document 1] Patent Publication No. JP11-113680 [Patent Document 2] Design Registration Gazette Design Registration No. 1684500

[0005] An example of the patent document 1 is shown in the explanatory diagram of Figure 4. That is, one end of the rear leg (9) is pivotally attached (28) to the seat part (3) of the chair seat main body (1), and a guide shaft (29) provided at the other end of the rear leg is adapted to engage with an engagement part (30) such as an engagement groove provided in the floor frame (13) of the leg member (2). Also, a guide groove (31) is provided in the floor frame (13) of the leg member (2) to guide the guide shaft (29) provided at the other end of the rear leg (9), and this guides the movement of the rear leg when the leg member (2) moves between the folded position and the unfolded position. This is because the chair seat is made of a material that does not undergo plastic deformation. DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0006] In response to the deficiencies and shortcomings of the prior art, the purpose of the present invention is to maximize the effect of acupressure on the lumbar vertebrae of a seated person while efficiently supporting the back when the seated person sits on a functional health chair. 1) For this purpose, acupressure is given using protrusions that correspond to the acupuncture points of traditional Chinese medicine on the buttocks and lower back of the human body. 2) Since the occupant can sit on the functional health chair and perform stretching exercises, the mechanical strength of the chair must be suitable for this purpose. 3) It has a structure and function that contributes to the "prevention of spinal canal stenosis." 4) It has a structure and functions that contribute to "Yin Yoga stretching." [Means for solving the problem]

[0007] In order to solve these problems, the present inventor has come up with the following invention. 1) In the functional health chair, the locations of the acupressure points in traditional Chinese medicine are clearly defined, and protrusions corresponding to those acupressure points are provided. 2) In order to ensure the mechanical strength of the functional health chair, the materials used are nylon synthetic resin and polyester fabric, and the mechanical compressive strength is increased to over 380 kg through injection molding. 3) The structure of the functional health chair contributes to the prevention of spinal canal stenosis, and in order to fulfill its function, it has an S-shaped structure that corresponds to the anatomical and ergonomic aspects of the spine. 4) The functional health chair has a structure that contributes to "Yin Yoga stretching" and a shape that corresponds to it in order to demonstrate its functions. 5) Regarding the functional health chair, the individual components of the structure are as follows: In one aspect of the present invention, the functional health chair of the present invention includes a first plate portion that accommodates the buttocks and thighs when the occupant is seated on the chair, a second plate portion that accommodates the waist and back when the occupant is seated on the chair, and a connecting portion that connects the first plate portion and the second plate portion, and the second plate portion can be formed with a shiatsu portion that comes into close contact with the waist when the occupant is seated on the chair.

[0008] In other words, the lower end of the acupressure part is connected to the connecting part, the upper end and side ends of the acupressure part are spaced apart from the second plate part, and the acupressure part is formed in one area at the central position of the second plate part, thereby providing the function of applying pressure and support to the lower back.

[0009] In one embodiment of the present invention, when the occupant sits on the chair and leans his / her back against the second plate portion, the second plate portion and the shiatsu portion are deformed with an elastic force, and the second plate portion and the shiatsu portion can have different restoring forces from each other.

[0010] The acupressure section has elasticity and is deformed to fit the occupant's lower back when the occupant sits on the chair, and includes a plurality of protrusions to further enhance the effect of acupressure on the lower back.

[0011] When the occupant sits on the chair and leans their body back, the front of the first plate portion drops downward due to the occupant's load (own weight), and the shiatsu portion can provide the shiatsu effect to the lower back with a stronger restoring force than the other parts of the second plate portion. Effect of the Invention

[0012] According to the present invention, when a person sits on a functional health chair, the effect of acupressure on the lumbar vertebrae of the person sitting on the chair can be maximized while efficiently supporting the back. 1) In the functional health chair, the locations of the acupressure points in traditional Chinese medicine are clearly defined, and protrusions corresponding to those acupressure points are provided, thereby enabling the effects of acupressure to be obtained. 2) In order to ensure the mechanical strength of the functional health chair, nylon synthetic resin and polyester fabric are used, and the mechanical compressive strength is increased to 380 kg or more through injection molding, allowing the seated person to safely perform back-arching stretching exercises on the functional health chair. 3) The structure of the functional health chair contributes to the prevention of spinal canal stenosis, and in order to fulfill its function, the S-shaped structure is designed to correspond to the anatomical and ergonomic aspects of the spine, making it possible to correct the spine to an S-shaped structure. 4) The functional health chair has a structure that contributes to "Yin Yoga stretching" and its functions, and is shaped accordingly to accommodate stretching exercises. 5) The functional health chair has a chair structure, so it can be used on a sofa, on the floor, outdoors, on a bench without a backrest, or in the driver's seat of a car.

FIG. 4 shows an embodiment of the chair seat made of a non-flexible material as described in Patent Document 1 (left image), and an embodiment of the chair as described in Patent Document 2 (right image), in which the seat can be slid forward by the user and, at the same time, the backrest becomes less inclined as the seat slides forward. FIG. 5 shows the strength test state of the functional health chair of the present invention. FIG. 6 is an explanatory diagram of the functional health chair of the present invention, which contributes to "prevention of spinal canal stenosis." FIG. 7 is an explanatory diagram of the functional health chair of the present invention that contributes to “Yin Yoga Stretch”. FIG. 8 is an explanatory diagram of the "stretching exercise" of the functional health chair of the present invention.

[0015] Referring to FIG. 1, reference numeral (710) indicates a state in which a person is not seated on the functional health chair (100), and reference numeral (720) indicates a state in which a person is seated on the functional health chair (100). As in the case of reference number (710), before the occupant sits on the functional health chair (100), acupressure portion (140) including a protrusion (145) protrudes forward from the peripheral surface of the second plate portion (130). As in the case of reference number (720), when a person sits on the functional health chair (100) and presses his / her body against the back, the connecting part (120) and the second plate part (130) are elastically deformed. When a person sits on the functional health chair (100), the front of the first plate part (110) moves downward due to the weight of the person, and the connecting part (120) and the second plate part (130) formed integrally with the first plate part (110) are in close contact with the user's waist and back while providing a certain elastic force. The second plate part (130) may have a shape curved forward in the longitudinal direction, and due to this shape, the second plate part (130) has a shape that can support the curved waist part and the back part by leaning backward when the person sits on the functional health chair (100), so that the waist part and other parts of the person are closely supported by the second plate part (130). As shown in FIG. 1A, the second plate portion 130 is configured to protrude forward from the connecting portion 120. As shown in FIG. 1B, the second plate portion 130 is configured to be pushed forward and curved so as to closely support the waist and back of the seated person when the seated person sits down. Referring to the drawing in FIG. 2, it can be clearly understood that the acupressure points in the buttocks and lower back of the human body in Oriental medicine are distributed symmetrically on the left and right sides with the spine as the center. 3, the functional health chair 100 is specifically shown as a functional health chair equipped with a shiatsu section 140. The functional health chair 100 has a first plate section 110, a second plate section 130, and a connecting section 120 that connects the first plate section 110 and the second plate section 130. The first plate portion 110 accommodates the buttocks and thighs of a seated person when seated on the functional health chair 100, and the second plate portion 130 accommodates the waist and back of a seated person when seated on the functional health chair 100. The first plate portion 110, the second plate portion 130, and the connecting portion 120 are integrally formed.

[0016] The first plate portion 110 is a seat plate on which the thighs and buttocks of a seated person are placed or arranged, and has a shape in which the front part is slightly raised upward. Depending on the embodiment, the first plate portion 110 may be provided with a removable plate-shaped cushion 115. The first plate portion 110 is preferably in a dish shape with an arc degree of 6 to 8 degrees.

[0017] The second plate portion 130 is a back plate that is extended rearward from the connecting portion 120 and supports the waist and back of a seated person. The second plate portion 130 has an appropriate curvature for closely contacting the waist and back, and may be connected to the first plate portion 110 via the connecting portion 120. The second plate portion 130 may be formed to be curved forward in the longitudinal direction, for example.

[0018] The connecting part 120 is a portion where the buttocks of a seated person are positioned when the seated person sits on the functional health chair 100, and may be curved as shown in the figure. The connecting part 120 and the second plate part 130 may include a flexible material that provides elasticity. Depending on the embodiment, not only the connecting part 120 and the second plate part 130 but also the first plate part 110 may be made of a flexible material.

[0019] The second plate portion 130 is formed with a shiatsu section 140 that comes into close contact with the lumbar region of the seated person when the seated person sits on the functional health chair 100. For example, the shiatsu section 140 is formed in an area at the center position of the second plate portion 130, and provides the function of applying pressure to and supporting the lumbar region of the seated person. The shiatsu section 140 can be formed integrally with the second plate portion 130.

[0020] In one embodiment of the present invention, the lower end of the acupressure part 140 is connected to the connecting part 120, and the upper end and side end of the acupressure part 140 are spaced apart from the second plate part 130. The acupressure part 140 protrudes from the surface of the second plate part 130. Due to this structural feature, when a seated person sits on the functional health chair 100 and leans his / her back against the second plate part 130, the second plate part 130 and the acupressure part 140 are deformed with elastic force, and here, the second plate part 130 and the acupressure part 140 may have different restoring forces. Since the acupressure part 140 protrudes forward from the second plate part 130, when a seated person leans his / her back against the second plate part 130, a stronger force is applied to the waist, which is the part of the body in close contact with the acupressure part 140, than to the remaining part of the body in close contact with the second plate part 130. The acupressure unit 140 provides strong pressure and force, maximizing the acupressure effect on the lumbar spine of the seated person. In one embodiment, when the seated person sits on the functional health chair 100 and leans his / her body backward, the front of the first plate unit 110 drops downward due to the load (self-weight) of the seated person, and the acupressure unit 140 can provide the acupressure effect to the seated person's lower back with a stronger restoring force than other parts of the second plate unit 130.

[0021] The acupressure unit 140 includes a plurality of protrusions 145 for stimulating the lower back area of ​​the seated person when the seated person is seated on the functional health chair 100. Such protrusions 145 may be made of various materials. The protrusions 145 may be arranged at a predetermined interval in the longitudinal direction of the second plate 130, or may be arranged symmetrically on the left and right. Such protrusions 145 serve to further enhance the effect of the acupressure on the lower back of the functional health chair 100.

[0022] The protrusions 145 in Fig. 1 should be positioned according to Fig. 2, which is a diagram showing the locations of acupuncture points on the buttocks and lower back of the human body in traditional Chinese medicine. This is the most important requirement of the present invention. When a person sits on the functional health chair (100) and presses his / her body against the back, the acupressure portion (140) also has elasticity and can deform to fit the waist of the functional health chair. In one embodiment, the acupressure section (140) can provide acupressure effects to the waist area of ​​the seated person with a stronger restoring force than other parts of the second plate section (130). The protrusions (145) formed on the acupressure section (140) can maximize the acupressure effects. The functional health chair (100) in which the first plate section (110), the second plate section (130), the connecting section (120) and the acupressure section (140) are integrally formed can provide acupressure effects to the seated person based on the elasticity of the acupressure section (140), and the functional health chair allows the seated person to sit in a correct posture. In addition, when the seated person sits on the functional health chair (100), the second plate section (130) can be separated into left and right sides based on the acupressure section (140), and as a result, the second plate section (130) can effectively support the seated person's back area. Industrial Applicability

[0023] The functional health chair 100 as described above can efficiently provide the effect of shiatsu to the lumbar region through the shiatsu unit 140 formed integrally with the first plate unit 110 and the second plate unit 130 without a complicated structure or hinge means. The shiatsu unit 140 and other components are formed integrally, so that the process for manufacturing the functional health chair 100 can be simplified and the cost spent on manufacturing the functional health chair 100 can be reduced. In addition, the functional health chair 100 including the shiatsu unit 140 can provide the effect of preventing deformation of the lumbar spine, fatigue, and lower back pain when a seated person sits on the chair. The seated person can feel comfort without pain in the lumbar spine through the functional health chair 100 and can maintain a correct posture while sitting comfortably on the functional health chair 100 for a long time.
