[0025] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

[0026] FIG. 1 is a perspective view of a functional complex desk system according to the first embodiment of the present invention. FIG. 2 is a view showing FIG. 1 at another angle. FIGS. 3 and 4 are a front view and a side view of FIG. 1, respectively. FIG. 5 is a control block diagram of the functional complex desk system of FIG. 1.

[0027] Referring to the drawings, the functional complex desk system 1 according to an embodiment of the present invention may track an optimal position suitable for a body condition or sitting posture of a user to automatically arrange a monitor 56 or main table 57, so that various work environments including study can be optimally implemented.

[0028] Referring to the drawings, the functional complex desk system 1 according to an embodiment of the present invention may include a system common base 10, an electromotive chair assembly 20, a side table assembly 30 and a monitor-equipped multi-joint table device 40.

[0029] Except for the side table assembly 30, the electromotive chair assembly 20 and the monitor-equipped multi-joint table device 40 are adjusted to various angles, that is, to the angle desired by the user, and particularly, automatically adjusted, so that the user can study, work, or play games in various postures in various environments. Accordingly, the convenience in use is highly improved.

[0030] The system common base commonly supports the electromotive chair assembly 20, the side table assembly 30, and the monitor-equipped multi-joint table device 40. In other words, the electromotive chair assembly 20, the side table assembly 30, and the monitor-equipped multi-joint table device 40 are mounted on the system common base 10, thereby being integrated into one body. In this case, the system can be kept compact and advantageous for moving.

[0031] The electromotive chair assembly 20 is mounted on one side of the system common base 10, and defines a seat for a user of the system of the present invention. The electromotive chair assembly 20 may have an angle arbitrarily varied by a chair button 21 therebelow. A massage function may be added to the electromotive chair assembly 20.

[0032] The side table assembly 30 refers to a structure arranged in a side region of the electromotive chair assembly 20 and coupled to the system common base 10. While the electromotive chair assembly 20 and the monitor-equipped multi-joint table device 40 are electromotive driven, the side table assembly 30 may be formed as a fixed structure.

[0033] The monitor-equipped multi-joint table device 40 refers to a type of articulated robot provided with a monitor 56 and a main table 57 disposed under the monitor 56 and movably supporting the monitor 56 and the main table 57. The monitor-equipped multi-joint table device 40 refers to a device arranged in a front region of the electromotive chair assembly 20 and coupled to the system common base 10.

[0034] In other words, the monitor-equipped multi-joint table device 40 is a set of robot, other than a simple table structure, is provided with the monitor 56 and the main table 57, and allows the monitor 56 and the main table 57 to be moved to a desired angle and position. Accordingly, the monitor 56 and the main table 57 are allowed to be automatically placed in an optimal position for the user sitting on the electromotive chair assembly 20.

[0035] For the reference, the monitor 56 may be a computer-built-in all-in-one monitor. In addition, the main table 57 may be mounted thereon with a keyboard, a mouse and the like for operating a computer. Reading books or taking notes is also available on the main table 57.

[0036] In the embodiment, the monitor-equipped multi-joint table device 40 may be disposed separately from the electromotive chair assembly 20 so as to prevent the shaking of the electromotive chair assembly 20 from being transferred to the monitor-equipped multi-joint table device 40. In other words, even when the user shakes a body while sitting on the electromotive chair assembly 20, the vibration is not transferred to the monitor-equipped multi-joint table device 40.

[0037] In addition, a user position tracking unit 81 and a system controller 70 are provided so that the monitor 56 and the main table 57 are automatically disposed in the optimal position for the user sitting on the electromotive chair assembly 20.

[0038] The user position tracking unit 81 serves to track an optimal position suitable for a body condition or posture of the user sitting on the electromotive chair assembly 20.

[0039] The above user position tracking unit 81 is provided in the monitor-equipped multi-joint table device 40, may be recognized through a sensor for tracking a face or eyes of the user in real time to measure an optimal distance of the user and transmitting the detected signal to the system controller 70 in real time, such as various distance measuring sensors using laser, infrared rays, ultrasonic wave and the like and a 3D scanning sensor.

[0040] In addition to the user position tracking unit 81, a voice recognition input unit 82 for inputting a voice signal for the operation of the monitor-equipped multi-joint table device 40 and connected to the system controller 70 may be further mounted.

[0041] The system controller 70 automatically controls the operation of the monitor-equipped multi-joint table device 40, such that the monitor 56 and the main table 57 are disposed in the optimal position according to a changed posture of the user based on the tracking signal of the user position tracking unit 81.

[0042] In particular, in the embodiment, the system controller 70 tracks the posture of the user through a predetermined real-time face-recognition or eye-tracking algorithm, and automatically controls the operation of the monitor-equipped multi-joint table device 40 according to the changed posture only when the same posture is maintained for a predetermined period of time. Regarding the operation of the operation of the monitor-equipped multi-joint table device 40 changed in real time, the posture of the user may be changed by a simple movement of the body or changed for other movements. When applied in real time, it may be changed to an unwanted angle or lead to an accident while moving.

[0043] The system controller 70 performing the above roles may include a central processing unit (CPU) 71, a memory 72, and a support circuit 73.

[0044] In the embodiment, the central processing unit 71 may be one of various computer processors industrially applicable to automatically control the operation of the monitor-equipped multi-joint table device 40 such that the monitor 56 and the main table 57 are disposed in the optimal position according to a changed posture of the user based on the tracking signal of the user position tracking unit 81.

[0045] The memory 72 is connected to the central processing unit 71. The memory 72, which serves as a computer-readable recording medium, may be installed locally or remotely, and may be, for example, at least one readily available memory such as a random access memory (RAM), ROM, a floppy disk, hard disk, or any form of digital storage.

[0046] The support circuit 73 is combined with the central processing unit 71 to support the typical operation of the processor. The support circuit 73 may include a power supply, a clock circuit, an input/output circuit, a subsystem, and the like.

[0047] In the embodiment, the system controller 70 automatically controls the operation of the monitor-equipped multi-joint table device 40 such that the monitor 56 and the main table 57 are disposed in the optimal position according to a changed posture of the user based on the tracking signal of the user position tracking unit 81, in which the series of control processes and the like may be stored in the memory 72. Typically, software routines may be stored in the memory 72. In addition, the software routines may be stored or executed by another central processing unit (not shown).

[0048] Although the process according to the present invention has been described as being executed by the software routines, at least some of the processes of the present invention may be performed by hardware. As the above description, the processes of the present invention may be implemented in software executed on a computer system, implemented in hardware such as an integrated circuit, or implemented by a combination of software and hardware.

[0049] According to the embodiment acting as the above-described configuration, an optimal position suitable for a body condition or sitting posture of a user may be tracked to automatically arrange a monitor 56 or main table 57, so that various work environments including study can be optimally implemented.

[0050] In particular, in the present embodiment, the individual adjustment function of each joint part constituting the monitor-equipped multi-joint table device 40 is configured to allow positions of the monitor 56 or the main table 57 to correspond to all customized conditions of the user. In addition, each joint part may be basically set by the user face recognition and automatic distance adjustment function. If necessary, the user may individually fine-tune each joint by using a corresponding control button to set the position to an optimized posture of the user, and the optimized setting values may be stored through an input button having a memory function. The memory function is useful when multiple users are present, and it is advantageous in that specific setting values may be stored in the memory according to each individual preference and then used via command buttons if necessary.

[0051] FIG. 6 is a perspective view of a functional complex desk system according to the second embodiment of the present invention. FIG. 7 is an operation state diagram of FIG. 6. FIGS. 8 to 10 are side views showing each process of the operation state of the functional complex desk system of FIG. 6. FIG. 11 is a control block diagram of the functional complex desk system of FIG. 6.

[0052] Referring to the drawings, the functional complex desk system 100 according to an embodiment of the present invention may also include a system common base 110, an electromotive chair assembly 120, a side table assembly 130 and a monitor-equipped multi-joint table device 140.

[0053] In particular, except for the side table assembly 130, since the electromotive chair assembly 120 and the monitor-equipped multi-joint table device 140 are adjusted to various angles, that is, to the angle desired by the user, so that the user can study, work, or play games in various postures in various environments. Accordingly, the convenience in use is highly improved.

[0054] The system common base 110 commonly supports the electromotive chair assembly 120, the side table assembly 130, and the monitor-equipped multi-joint table device 140.

[0055] In other words, the electromotive chair assembly 120, the side table assembly 130, and the monitor-equipped multi-joint table device 140 are mounted on the system common base 110, thereby being integrated into one body. In this case, the system can be kept compact and advantageous for moving.

[0056] The electromotive chair assembly 120 is mounted on one side of the system common base 110, and defines a seat for a user of the system of the present invention.

[0057] The electromotive chair assembly 120 may include: an electromotive chair body 123 having a seat plate 121 and a backrest 122; an electromotive foot support 124 connected to the electromotive chair body 123 to support feet and legs; a chair-mounted driving unit 125 provided on the system common base 110 to support the electromotive chair body 123 and drive the electromotive chair body 123 and the electromotive foot support 124. The operation of the chair-mounted driving unit 125 may be controlled by a system controller 170 described later.

[0058] As the above description, since the electromotive chair body 123 and the electromotive foot support 124 may be operated, that is, rotated due to the electromotive structure of the chair-mounted driving unit 125, the sitting position may be adjusted to several angles. Further, the electromotive chair assembly 120 may be used even in an almost lying position.

[0059] For the reference, although not shown in the drawing, a massage function may be added to the electromotive chair body 123 and the electromotive foot support 124. In this case, the electromotive chair assembly 120 may be a complex device having an added massage function beyond the concept of a chair only.

[0060] The side table assembly 130 refers to a structure arranged in a side region of the electromotive chair assembly 120 and coupled to the system common base 110.

[0061] While the electromotive chair assembly 120 and the monitor-equipped multi-joint table device 140 are electromotive driven, the side table assembly 130 is formed as a fixed structure.

[0062] The side table assembly 130 may include a side table 131, and a plurality of side bridges 132 having an upper part supporting the side table 131 and a lower part fixed to the system common base 110.

Due to the action of the third actuator 154, the third rotating arm 152 may be relatively rotated with respect to the second rotating arm 147 about the third 151 as an axial center.

[0074] Due to the above structures, that is, the action of the first actuator 145, the second actuator 149 and the third actuator 154, each of the first rotating arm 143, the second rotating arm 147, and the third rotating arm 152 may be relatively rotated with respect to the fixed mount 141 fixed in position, and accordingly, the monitor 156 and the main table 157 may be rotated to a desired angle.

[0075] In addition, in the embodiment, the functional complex desk system 100 is provided with an input panel 160 and a system controller 170 for controlling the system.

[0076] The input panel 160 has a plurality of function buttons 161 so as to operate the electromotive chair assembly 120 and the monitor-equipped multi-joint table device 140 at various angles and positions as shown in FIGS. 6 to 10 or not shown therein.
