[0023] Effects of the Invention

[0024] The hairdressing and beauty chair of the present invention comprises a chair body, a cover, a shampooing basin and a connecting part, wherein the chair body comprises a seat, a backrest and a frame part supporting the seat and the backrest; the cover surrounds the side and rear of the chair body, and the rear side is opened and closed; the shampooing basin is placed on the head of the operator; the connecting part connects the shampooing basin and the chair body; the shampooing basin changes to a storage state arranged below the seat or an operation state arranged behind the backrest. That is, the shampooing basin is connected to the chair body via the connecting part, and is in a storage state when not in use, but changes to an operation state when in use. In the storage state, since the shampooing basin is stored below the seat and covered by the cover, the shampooing basin cannot be seen from the periphery of the hairdressing and beauty chair. On the other hand, in the operation state, since the shampooing basin is arranged behind the backrest and the head of the operator is placed, the operation can be performed. Therefore, the shampooing basin can be quickly prepared when needed, and the shampooing basin can be excluded from the operator's field of vision when not needed.

[0025] In the hairdressing and beauty chair of the present invention, the connecting part is a link mechanism that displaces the shampoo bowl in a certain posture. That is, the shampoo bowl is changed into a storage state or an operation state by maintaining the hemispherical upward posture on which the operator's head is placed by the link mechanism. Therefore, water drops attached to the inner surface of the shampoo bowl will not overflow, and there is no need to disassemble the drain pipe every time the state is changed.

[0026] The barbershop chair of the present invention has a four-bar linkage mechanism, which has two link parts, which are connected to the chair body as fixed ends and to the shampooing basin as free ends. Therefore, the shampooing basin can reciprocate between the bottom of the seat and the back of the backrest while maintaining a certain posture.

[0027] The hairdressing chair of the present invention can change the height of the shampoo bowl in the above-mentioned operation state. With this structure, the height of the shampoo bowl can be finely adjusted to a height that is easy to operate in the operation state according to the operator's physical condition.

[0028] The hairdressing and beauty chair of the present invention includes a plurality of postures with different heights of the shampoo bowl as the operating state. Therefore, the shampoo bowl can be set in advance at a height suitable for operation, and can be automatically moved to the set height.

[0029] In the hairdressing and beauty chair of the present invention, when in operation, the height of the shampoo bowl is changed as fine adjustment, and the change amount of the shampoo bowl moving forward and backward is less than the change amount of the height of the shampoo bowl in the fine adjustment. With this structure, fine adjustment can be made to a height that is easy for the operator to operate.

[0030] The hairdressing and beauty chair of the present invention has a driving unit for operating the link mechanism. Therefore, the link mechanism is automatically operated by the driving unit.

[0031] In the hairdressing and beauty chair of the present invention, the rear side of the cover changes to the storage state or the operation state only when it is opened to a greater degree than a predetermined opening, thereby preventing damage caused by interference between the rear side of the cover and the shampoo bowl.

[0032] In the hairdressing and beauty chair of the present invention, the shampooing basin has a neck support for placing the neck of the operator, and the neck support is deformed and accommodated inside the shampooing basin. That is, even if the neck support is large and becomes an obstacle to the storage state, the neck support does not hinder the storage state by being accommodated inside the shampooing basin.

[0033] In the hairdressing and beauty chair of the present invention, the neck support has a baffle portion that is higher than the side wall portion of the shampooing bowl, and the baffle portion is deformed together with the neck support and accommodated inside the shampooing bowl. That is, the neck support has a baffle portion for preventing hot water from rebounding and splashing outside the shampooing bowl. In this case, even if the baffle portion is large in size and becomes an obstacle to the storage state, the baffle portion does not hinder the storage state by being accommodated inside the shampooing bowl.

[0034] In the hairdressing and beauty chair of the present invention, the supply of hot water to the shampooing basin in the storage state is automatically stopped. The drain pipe is also deformed in accordance with the change of the storage state or the operation state. At this time, since the drain pipe in the storage state extends toward a position higher than the drain port of the shampooing basin, the hot water is not drained when the hot water is continuously supplied, and the hot water overflows. Therefore, by detecting the storage state and automatically stopping the supply of hot water, the hot water overflow can be prevented.

[0035] The hairdressing chair of the present invention has a hair dryer above the shampoo bowl in the stored state. That is, in the stored state, the shampoo bowl is difficult to be exposed to the outside air because it is surrounded by the cover, so the shampoo bowl is not easy to dry, but the shampoo bowl can be dried by the hair dryer.

A motor of the blower 69 (not shown) is installed on the top of the bottom frame 38. In addition, a lifting unit for lifting the seat 3 and an actuator 24 for lowering or raising the backrest 5 are also installed.

[0076] Next, the guide rail portion 39 will be described. Figure 7~Figure 9As shown, the pair of left and right guide rails 39 face the guided portion 21 of the shampoo bowl 12, and slide through the guided portion 21 to stabilize the movement of the four-bar linkage 44 and the track of the shampoo bowl 12. The guide rail 39 extends in the front-to-back direction at the lower part of the outer frame 36, and gradually becomes higher from the rear to the front, in other words, gradually becomes lower from the front to the rear. The guide rail 39 has a first protrusion 40 at the front end; a first inclined portion 41 inclined downward as it moves from the first protrusion 40 toward the rear; a flat portion 42 extending toward the rear from the first inclined portion 41; and a second inclined portion 43 inclined downward as it moves from the flat portion 42 toward the rear.

[0077] Next, the operation of the four-bar linkage 44 will be described with reference to the drawings. Figure 10~Figure 13 In order to explain the operation of the four-bar linkage 44 and the track of the shampoo bowl 12, the four-bar linkage 44 is briefly shown with components omitted appropriately. In addition, since the operation of each left and right four-bar linkage 44 is the same, only the operation of the left four-bar linkage 44 shown in these figures will be described below.

[0078] like Fig.10 As shown, in the storage state, the shampoo basin 12 is arranged below the seat 3 and stored in the storage chamber 8. If the driving unit 68 is working, the left second link portion 62 is pushed backward, and the left second link portion 62 (at Fig.10 The left first link portion 57 follows the left second link portion 62 and rotates the left first fixed joint 59 as the rotation axis (in the counterclockwise direction). Fig.10 Since the left first link portion 57 and the left second link portion 62 are both curved in a convex arc shape, a U shape, or a V shape toward the front, the track of the shampoo bowl 12 connecting the left first free end portion 60 and the left second free end portion 65 moves approximately horizontally backward and comes out of the storage chamber 8. When or after coming out of the storage chamber 8, the shampoo bowl 12 moves while drawing an arc upward and obliquely backward, such as Fig.11 and 12 As shown, the operation state is reached. At this time, the shampoo bowl 12 is displaced while maintaining the hemispherical face-up posture. In the operation state, when the operator lies on the chair body 2 with the backrest 5 in the down position, the shampoo bowl 12 is arranged at a position where the head is placed on the shampoo bowl 12. The operation state includes a plurality of postures with different heights of the shampoo bowl 12, for example, a height suitable for the operator to sit on a stool or the like and perform the operation unchanged (hereinafter referred to as "seat operation") (see Fig.11 ), height suitable for the operator to stand up and perform operations without changing position (hereinafter referred to as "standing operation") (refer to Fig.12), etc. They are all pre-set and automatically shifted.

[0079] like Fig.13 As shown, the shampoo bowl 12 is further displaced up and down by the operation of the driving unit 68 in either the seated operation or the standing operation, and the height of the shampoo bowl 12 is finely adjusted. At this time, the amount of change of the shampoo bowl 12 is less than the height. Therefore, the shampoo bowl 12 is displaced substantially vertically while maintaining the same posture.

[0080] Next, the operation of the guide rail portion 39 will be described based on the drawings. Figure 14~Figure 17 3 shows a state in which the guided portion 21 of the shampoo bowl 12 slides relative to the guide rail portion 39 during the process of changing from the stored state to the operating state.

[0081] like Fig.14 As shown in FIG. 1 , in the storage state, the guided portion 21 of the shampooing basin 12 abuts against the first protrusion 40 of the guide rail portion 39 and sits on the first inclined portion 41. If the left and right four-bar linkages 44 work, then Fig.15 As shown in FIG. 1 , the guided portion 21 slides on the first inclined portion 41, and at the same time, the shampoo bowl 12 moves backward. If the shampoo bowl 12 moves further, Fig.16 As shown, the guided portion 21 slides on the flat portion 42, as shown in FIG. Fig.17 As shown, the guided portion 21 leaves the flat portion 42 and comes out of the storage chamber 8. Figure 14~Figure 17 As shown, during the entire process from the storage state to the exit of the shampoo bowl 12 from the storage chamber 8, the guided portion 21 continues to contact the entire area of ​​the guide rail portion 39. In addition, when changing from the operating state to the storage state, the guided portion 21 continues to contact the entire area of ​​the guide rail portion 39 in the reverse order to the above.

[0082] Next, the neck support member 70 will be described based on the drawings. Fig.18 and Fig.19 The shampoo basin 12 is shown in the figure when it enters the storage chamber 8. Fig.18 In the figure, the state in which the neck support member 70 can be used (hereinafter referred to as "use state") is indicated. Fig.19 70 is shown in a state where the neck support member 70 is deformed and accommodated in the shampoo bowl 12 (hereinafter referred to as the "unused state"). Fig. 20 The neck support 70 is only shown in the use state. Fig.21 Only the neck support member 70 in the non-use state is shown.

[0083] like Fig.18As shown, the neck support member 70 has a deformable neck support body 71 and a neck support recess 84 and a neck support protrusion 85 installed on the neck support body 71. The neck support recess 84 is concave in shape for placing the neck of the person being operated, and the neck support protrusion 85 is spherical in shape for placing the back of the head near the neck of the person being operated. The neck support member 70 has a baffle portion 86 installed on the neck support member 70 around the neck support member 70. The baffle portion 86 is connected to the left and right sides of the neck support recess 84 and is arranged on the left and right sides of the neck support body 71. The baffle portion 86 is higher than the side wall portion 14 of the shampoo bowl 12. The neck support body 71 and the baffle portion 86 stand up on the outside of the storage chamber 8 and are in use, but when entering the storage chamber 8, they are deformed by the operator or by abutting against the plate-like member 9, as shown in FIG. Fig.19 As shown, the hair washing bowl 12 is turned upside down and stored in an unused state.

[0084] like Fig. 20 and Fig.21 As shown, the neck placement body 71 is connected to three components, and the neck placement body 71 is deformed and changed in height by the linkage of the three components. The neck placement body 71 includes a base portion 72 mounted on the shampoo bowl 12; an intermediate rotating portion 75 connected to and supported by the base portion 72; and a neck support base 79 connected to and supported by the intermediate rotating portion 75. The base portion 72 includes a flat base plate portion 73 and a base shaft portion 74 protruding from the upper surface of both ends of the base plate portion 73. The intermediate rotating portion 75 includes a rod-shaped rotating base 76; a base side arm portion 77 protruding backward from both ends of the rotating base 76; and a neck support side arm portion 78 protruding upward from both ends of the rotating base 76. The neck support base 79 includes a rod-shaped first support base 80; a support base arm portion 83 protruding upward from both ends of the first support base 80; and a rod-shaped second support base 81 connected to the upper end of the support base arm portion 83. A support-side shaft portion 82 is formed on the outer side surface of the support base arm portion 83 .

[0085] The base side arm portion 77 of the intermediate rotating portion 75 is connected to the base shaft portion 74 of the base portion 72, and the neck support side arm portion 78 of the intermediate rotating portion 75 is connected to the support side shaft portion 82 of the neck support base portion 79. Therefore, the intermediate rotating portion 75 rotates with the base shaft portion 74 as the rotation axis, and the neck support base portion 79 rotates with the support side shaft portion 82 as the rotation axis. If the intermediate rotating portion 75 rotates, the neck support side arm portion 78 falls backward toward the inside of the shampoo bowl 12, and therefore, the neck support base portion 79 also falls backward toward the inside of the shampoo bowl 12 while rotating. If the neck support member 70 falls down, the baffle portion 86 also falls down with it. Therefore, if Fig.19 As shown, the neck rest 70 and the baffle portion 86 are lower than the side wall portion 14 of the shampoo bowl 12 .

[0086] Next, the control performed by the control unit is described. The control mainly includes non-interference control between the shampoo bowl 12 and the lower back door cover 32 (hereinafter referred to as "non-interference control"); position control between the shampoo bowl 12 and the backrest 5 (hereinafter referred to as "position control"); non-linkage control between the shampoo bowl 12 and the lifting and lowering of the seat 3 (hereinafter referred to as "non-linkage control"); water supply control to the shampoo bowl 12 (hereinafter referred to as "water supply control"); and drying control of the shampoo bowl 12 (hereinafter referred to as "drying control").

[0087] In the non-interference control, only when the lower rear door cover 32 is opened to a greater extent than a predetermined opening (see Fig.18 ) changes the state of the shampoo bowl 12. Here, the predetermined opening refers to the degree to which the displaced shampoo bowl 12 does not contact the lower back door cover 32. If the sensor detects that the lower back door cover 32 is closed and sends a signal to the control unit, the control unit does not operate the drive unit 68 of the four-bar linkage 44. If the sensor detects that the lower back door cover 32 is opened and exceeds the predetermined opening and sends a signal to the control unit, the control unit releases the restriction of the drive unit 68.

[0088] In the position control, when the backrest 5 falls down (refer to Figure 5 ), the state change of the shampoo bowl 12 is limited. Specifically, if the sensor detects that the backrest 5 is in a fallen posture and the shampoo bowl 12 is in an operating state and sends a signal to the control unit, the control unit does not operate the driving unit 68 of the four-bar linkage 44. In the position control, when the shampoo bowl 12 is displacing, the backrest 5 does not move. Specifically, if the sensor detects that the shampoo bowl 12 is displaced and sends a signal to the control unit, the control unit does not operate the actuator 24. On the other hand, if the sensor detects that the shampoo bowl 12 is stopped and sends a signal to the control unit in the operating state, the control unit releases the restriction of the actuator 24. In the position control, the degree to which the backrest 5 is made to fall down is different in the operating state and the storage state. Specifically, the degree to which the backrest 5 falls down in the storage state is greater than the degree to which the backrest 5 falls down in the operating state. Therefore, the backrest 5 in the storage state is closer to horizontal than in the operating state. If the sensor detects that it is an operating state or a storage state and sends a signal to the control unit, the control unit selects the operating range of the actuator 24 according to the state.

[0089] In the non-linked control, when the shampoo bowl 12 is in the operating state (refer to Figure 5 ), limiting the lifting of the seat 3. Specifically, if the sensor detects that the lower back door cover 32 is opened beyond a prescribed opening and sends a signal to the control unit, the control unit limits the lifting unit.

[0090] In the water supply control, when the shampoo bowl 12 is in the storage state, the supply of hot water to the shampoo bowl 12 is automatically stopped. Here, the meaning of the water supply control is described based on the drawings. Fig. 22 The posture of the drain pipe 17 in the operating state is shown in Fig.23 The figure in the middle shows the posture of the drain pipe 17 in the stored state.

[0091] like Fig. 22 As shown in FIG. 1 , the drain pipe 17 is composed of a straight pipe 18 connected to the drain port 15 at the inner side of the shampoo bowl 12, a flexible pipe 19 connected to the straight pipe 18, and a return bend pipe 20 connected to the flexible pipe 19. In the operating state, the drain pipe 17 extends from the inner side of the shampoo bowl 12 toward the front and obliquely downward, so the hot water flows down and is discharged naturally. Fig.23 As shown, in the stored state, the drain pipe 17 extends to a position higher than the drain port 15 through the straight pipe 18 facing up and down and the flexible pipe 19 bending upward. Therefore, since it is not drained naturally, it is necessary to prevent overflow caused by forgetting to tighten the water stop valve 16.

[0092] Therefore, in the water supply control, when the sensor detects that the shampoo bowl 12 is in the storage state and sends a signal to the control unit, the control unit operates the electromagnetic valve, and the electromagnetic valve restricts the water supply.

[0093] In the drying control, when the shampoo bowl 12 is in the storage state, the hair dryer 69 (see Fig. 9 ) Dry the shampoo bowl 12 (refer to Figure 8 Specifically, in the storage state, when the fan of the hair dryer 69 is located above the shampoo bowl 12, if the sensor detects that the shampoo bowl 12 is in the storage state and sends a signal to the control unit, the control unit operates the motor of the hair dryer 69.

[0094] The hair cutting and beauty treatment chair 1 is constructed as described above. Next, the effects of the hair cutting and beauty treatment chair 1 will be described.

[0095] As described above, the hairdressing and beauty chair 1 includes the chair body 2; the cover 26 surrounding the left and right sides and the rear of the chair body 2; the shampooing basin 12 whose rear side is opened and closed to change to the storage state or the operation state; and the four-bar linkage 44 connecting the shampooing basin 12 and the chair body 2, wherein the cover 26 reaches the vicinity of the installation surface. In the storage state, the shampooing basin 12 is arranged below the seat 3, stored in the storage chamber 8, and covered by the cover 26, so that the shampooing basin 12 cannot be seen from the periphery of the hairdressing and beauty chair 1. On the other hand, in the operation state, when the operator lies on the chair body 2 with the backrest 5 in a fallen posture, the shampooing basin 12 can be arranged in a position where the head is placed on the shampooing basin 12 for operation. Therefore, the shampooing basin 12 can be quickly prepared when needed, and the shampooing basin 12 can be excluded from the operator's field of vision when it is not needed.

[0096] The hairdressing and beauty chair 1 has the left and right four-bar linkages 44, and the shampoo bowl 12 changes between the storage state and the operation state while maintaining the hemispherical face-up posture by the left and right four-bar linkages 44. Therefore, water drops adhering to the inner surface of the shampoo bowl 12 will not overflow, and the drain pipe 17 and the like do not need to be removed and attached every time the state is changed.

[0097] In the hairdressing and beauty chair 1, as the operation states, a plurality of postures of different heights of the shampoo bowl 12 are pre-set, and a height suitable for seated operation and a height suitable for standing operation are pre-set. Therefore, the shampoo bowl 12 can be automatically displaced to the set height.

[0098] In the hairdressing and beauty chair 1, the height of the shampoo bowl 12 can be further adjusted by moving up and down in any operation position of the seat operation or the standing operation. Therefore, the height of the shampoo bowl 12 can be finely adjusted to a height that is easy to operate according to the operator's physical condition.

[0099] In the hair cutting and beauty treatment chair 1, each of the left and right four-bar linkages 44 automatically operates by the operation of the driving unit 68, so it is simple and convenient.

[0100] In the hairdressing and beauty chair 1, the state of the shampoo bowl 12 is changed by non-interference control only when the lower back door cover 32 is opened larger than a predetermined opening. Therefore, damage caused by interference between the lower back door cover 32 and the shampoo bowl 12 can be prevented.

[0101] In the hairdressing and beauty chair 1, the front part of the side wall part 14 of the shampoo bowl 12 is recessed, and the neck rest 70 is installed. When the neck rest 70 enters the storage chamber 8, it is tilted toward the inside of the shampoo bowl 12 by the operator or by abutting against the plate-shaped member 9, and is stored in an unused state. That is, even if the neck rest 70 is large in size and becomes an obstacle to the storage state, the neck rest 70 is stored inside the shampoo bowl 12 without hindering the storage state.

[0102] In the hair cutting and beauty treatment chair 1, the neck rest 70 has a baffle portion 86 surrounding the neck rest 70, and the baffle portion 86 is higher than the side wall portion 14 of the shampoo bowl 12. The baffle portion 86 prevents hot water from rebounding and splashing outside the shampoo bowl 12. In addition, even if the baffle portion 86 is large and becomes an obstacle to the storage state, the baffle portion 86 is stored inside the shampoo bowl 12 along with the neck rest 70, so that the storage state is not hindered.

[0103] In the hairdressing and beauty chair 1, the solenoid valve is connected to the water supply part for supplying hot water, and in order to prevent water overflow caused by forgetting to tighten the water stop valve 16 in the storage state, the supply of hot water to the shampooing basin 12 is automatically stopped by the solenoid valve as a water supply control in the storage state. Therefore, it is possible to prevent hot water from overflowing.

[0104] In the hairdressing and beauty chair 1, a hair dryer 69 for blowing air toward the storage chamber 8 is installed on the bottom frame portion 38. In order to dry the shampoo bowl 12 which is not easy to dry due to being surrounded by the cover portion 26, as a drying control, the hair dryer 69 is operated when the shampoo bowl 12 is in the storage state, so that the shampoo bowl 12 can be dried.

[0105] In addition, in other embodiments of the present invention, there is no driving unit, and the shampoo bowl is displaced manually.

[0106] In other embodiments, the driving unit that operates the four-bar linkage is, for example, a motor.

[0107] In other embodiments, the posture included in the operating state is one.

[0108] In other embodiments, the number of postures included in the operation state is three or more.

[0109] Other embodiments do not allow for adjustments in the operating state.

[0110] Other embodiments do not have a neck support.

[0111] Other embodiments have a neck support but no baffle portion.

[0112] In another embodiment, the neck rest and the baffle are lower than the side wall of the shampoo bowl.

[0113] In other embodiments, the control unit has any one or more of non-interference control, position control, non-linkage control, water supply control, and drying control.

[0114] In other embodiments, the control unit does not have non-interference control, position control, non-interlocking control, water supply control, or drying control.

[0115] In other embodiments, there is no blower.

[0116] In another embodiment, the hinge for opening and closing the lower rear door cover is the rear portion of the left side portion.

[0117] Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above embodiments. In addition, the present invention can be modified in various designs as long as it does not depart from the matters described in the claims.
