1 to 4, the fixed bar 130 may be erected on the base 101 and installed on the mounting plate 102, as shown in FIGS. 1 to 4, Or may be installed directly on the mounting plate 102 irrespective of the base 101 or mounted upright on the base 101 independent of the mounting plate 102 and in any case, It belongs to the scope.

In the shampoo electric chair according to an embodiment of the present invention, the seat 140 includes a seat body 140a on which a seat cushion 140 'is installed, and a seat back 140b protruding upward from a rear end of the seat body 140a. The backrest 150 includes a backrest body 150a on which a backrest cushion 150 'connected to a washstand (not shown) is installed, and a backrest body 150b protruding upward from a front end of the backrest body 150a And the backrest fastening part 140b and the seat fastening part 150b are connected to each other by the eleventh connection part 150b and the rear fastening part 150b formed forwardly at the lower end of the backrest body 150a, The rear end of the two horizontal operation links 182 is connected to the seat 140 and the backrest 150 by means of the ninth connecting pin P9, The leg support 160 is rotatably connected to the leg support 150c, The cushions 160 'are provided.

In the shampoo electric chair according to an embodiment of the present invention, the pedestal support link 170 may include a pedestal support link 170 having one end connected to the distal end of the fixed rod 130 to be rotatable by the second connection pin P2, And an upper support link 172 connected at the other end to the support bracket 162 so as to be rotatable by a fourth connection pin P4. The lower support link 171 One end of the other end supporting link 172 is rotatably connected by a third connecting pin P3 and the front end of the first horizontal operating link 181 is connected to the lower supporting link 171 of the pedestal And the operation of moving the lower support link 171 and the upper support link 172 of the pedestal base around the third connection pin P3 in accordance with the movement of the first horizontal operation link 181 forward and backward .

Accordingly, there is an advantage that the leg-rest 160 can be smoothly expanded and folded while supporting the leg-rest 160 firmly.

In the shampoo electric chair according to an embodiment of the present invention, a second seat bracket 142 is protruded downward from the first seat bracket 141 and spaced forward from the seat 140, The reinforcing link 130 is rotatably connected to the front end of the fixed bar 130 by a second connecting pin P2 and the other end is rotatably connected to the second seat bracket 142 by a seventh connecting pin P7. 190) are further included.

According to this, there is an advantage that the durability of the product can be improved because the sheet 140 can withstand a large load applied thereto without interfering with the lifting and lowering of the sheet.

In the shampoo electric chair according to an embodiment of the present invention, the rotary bar 120 is rotatably mounted on the pair of mounting plates 102 by a rotary shaft 103, A detent pin 104 provided on the pair of mounting plates 102 so as to be spaced apart from the rotating shaft 103 in parallel to the rotating shaft 103 and to be rotated in one direction or the other direction And further comprises guide grooves 123 which are formed in an arc shape on the rotary bar 120 and are extrapolated on the stop pins 104 to prevent the rotation of the rotary bar 120 (i.e., to set the maximum rotation angle) .

According to this, there is an advantage that the maximum rotation angle of the rotary arm can be set by a simple mechanical configuration without depending on the electric circuit configuration.

In the shampoo electric chair according to an embodiment of the present invention, the rotating rod base rotating means 111, 112 and 113 include an electric motor 111, a screw rod 112 which is installed in the electric motor 111, And a screw nut 113 which is engaged with the screw rod 112 and moves forward or backward along the screw rod 112 in accordance with rotation of the screw rod 112.

At this time, the lower end of the rotary bar 120 is connected to the screw nut 113 and rotates down when the screw nut 113 is advanced, and rotates upward when the screw nut 113 is retracted .

According to the above configuration, there is an advantage that the rotary bar 120 can be rotated quickly by a simple structure.

As shown in the figure, since the lower end of the rotary bar 120 is supported by the screw nut 113 and rotates about the rotary shaft 103, an advantage of being able to maintain a stable state without flowing before and after the upward movement of the seat 140 have.

The operation of the electric shampoo chair according to one embodiment of the present invention will now be described.

When the electric motor 111 rotates forward, the screw rod 112 is rotated forward and the screw nut 113 is moved back along the screw rod 112 in accordance with the rotation of the screw rod 112, .

As described above, when the rotary bar 120 rotates in one direction (counterclockwise), the seat 140 is raised and the first horizontal actuating link 181 and the second horizontal actuating link 182 are advanced.

That is, when the rotary bar 120 rotates in one direction (counterclockwise), the second horizontal actuating link 182 connected to the end is pulled forward and the first horizontal actuating link 181 connected to the center is advanced forward by pushing forward.

When the first horizontal operation link 181 is advanced as described above, the lower pedestal support link 171 and the pedestal upper support link 172 are expanded and the leg support 160 is unfolded (FIG. 2).

When the second horizontal operation link 182 advances, the backrest 150 is turned backward while being rotated counterclockwise in the same direction as the rotary bar 120 with the eleventh connection pin P11 as a rotation axis 2).

As described above, the seat 140 is lifted by one rotation of the rotary bar 120, and the backrest 150 is lifted backward, so that the legrest 160 can be unfolded.

At this time, as shown in FIG. 2, the left end of the guide groove 123 (referring to the direction of the view of FIG. 1) is caught by the stop pin 104 and the rotation of the rotating rod 120 is stopped, There is an advantage that the rotation of the rotary bar 120 can be stopped without implementing an electronic circuit.

The user performs a shampoo (hair washing) in a state in which the seat 140 is lifted and the backrest is turned and the leg-rest 160 is extended as shown in Fig. 2, and when the operation is completed, the seat 140 descends and is lifted The backrest is returned to its original position and the extended leg support 160 is folded downward. This is started by rotating the electric motor 111 in the reverse direction, and is a reverse process of the above-described operation.

When the electric motor 111 rotates in the reverse direction, the screw rod 112 rotates reversely and the screw rod 113 advances along the screw rod 112 according to the rotation of the screw rod 112, .

As described above, when the rotary bar 120 rotates in the other direction (clockwise), the seat 140 is lowered and the first horizontal operation link 181 and the second horizontal operation link 182 are reversed.

That is, when the rotary bar 120 rotates in the other direction (clockwise), the second horizontal operation link 182 connected to the end is pushed backward and the first horizontal operation link 181 connected to the central portion is pulled backward.

When the first horizontal operation link 181 is retracted as described above, the lower pedestal support link 171 and the pedestal upper support link 172 are folded to fold the leg support 160 (FIG. 1).

When the second horizontal operation link 182 is retracted, the backrest 150 is rotated forward in the clockwise direction in the same direction as the rotary bar 120 with the eleventh connection pin P11 as a rotation axis (FIG. 1) .

As described above, the seat 140 can be lowered and the backrest 150 and the leg-rest 160 can be erected by rotating the rotary bar 120 once.

At this time, the end of the right side of the guide groove 123 (relative to the direction of the view of FIG. 1) is caught by the stop pin 104, and the rotation of the rotating rod 120 is stopped.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or scope of the invention as defined in the appended claims. It is self-evident to those who have.

Therefore, the above-described embodiments are to be considered as illustrative rather than restrictive, and the present invention is not limited to the above description, but may be modified within the scope of the appended claims and equivalents thereof.
