BACKGROUND OF THE INVENTION

1. Field of Invention
The present invention relates to a furniture structure for placing an electronic device, and more particularly, to a furniture structure for placing an electronic device that allows a user to operate the electronic device when the user's hands naturally drop down.
2. Related Art
Nowadays, people are rich, and enjoy the high-quality life. However, diseases do not become diminished as the progress of the times; instead, people are suffering from more diseases. Besides diseases caused by bacteria, a new term “disease of civilization” has been put forward in recent years, which is caused by the change of life styles and habits. Especially, as computers are used at anytime and anywhere, when the user uses the computer for a long time with a wrong posture, the muscles and joints are contracted and compressed for a long time, and as time passes by, pathological changes occurs for these muscles and joints, and sometimes even deformation of the joints may occur. For example, when operating a computer, the mouse is an indispensable device, which is always placed on a table. As shown in FIG. 1, a hand 100 of the user must be put on a table 150, with a palm 110 holding a mouse 130 to operate the mouse 130. However, this motion of the hand makes the scapula to move upwards, extend outwards, and hang at a high position, the shoulder joint to flex and extend outwards, the forearm to hang forwards, the wrist to extend, and the finger joints to extend outwards and flex. Therefore, this motion makes the muscles of the neck, shoulder, upper back, and arms to be contracted. If the motion is kept for a long time, the aforementioned muscles become tired and rigid, and thus causing arthritis and inflammation of the muscles.
Hence, if the mouse is used on a desk, a table, a computer table, or a keyboard shelf, the hand in operation makes the scapula to move upwards, extend forwards, and rotate upwards, the shoulder joint to flex and extend outwards, the elbow joint to flex, the forearm to rotate forwards, the wrist joint to extend, the metacarpophalangeal joints of the fingers to extend, the distal interphalangeal joints of the fingers to flex, the fingers to extend outwards, the metacarpophalangeal joint and the interphalangeal joint of the thumb to flex, and the thumb to adduct, so as to complete the entire motion. That is, to complete the motion, the brain must give a command and the nerves must transmit signals, so as to simultaneously control the major or other minor muscles participating in the motion to contract, such as trapezius, levator scapula (to make the scapula to move upwards), serratus anterior (to make the scapula to extend outwards and rotate upwards), deltoid, coracobrachialis, supraspinatus (to make the shoulder joint to flex), biceps brachii, brachialis, brachioradialis (to make the elbow joint to flex), pronator teres, pronator quadratus (to make the forearm to rotate forwards), the extensor carpi radialis longus, extensor carpi radialis brevis (to make the wrist joint to extend), extensor digitorum, extensor digitorum longus, intrinsic extensor digiti minimi (to make the metacarpophalangeal joints of the fingers to extend), dorsal interossei (in the hand), abductor digiti minimi (makes the finger to extend outwards),flexor pollicis brevis, flexor pollicis longus (to make the metacarpophalangeal joint and the interphalangeal joint of the thumb to flex), and adductor pollicis (to make the thumb to adduct), and to control the antagonists to relax.
An ordinary person often operates the computer continuously for scores of minutes or even several hours. As time elapses, the aforementioned muscle groups are overused, and become tired and rigid, which lead to the problems of neck rigidity, upper back pain, interscapular pain, pain of shoulder, elbow, and wrist joints, radial styloiditis (De Quervain's disease), and carpal tunnel syndrome. However, the user has to maintain the same posture and repeat the operation continuously as required by the environment and type of the work, and thus, the symptoms of sores and pains cannot be eliminated even after various treatments. Currently, many auxiliary tools for mice are available on market, such as various mouse pads, which are disposed with high supporting cushions close to a position where the wrist joint is placed. The cushions even have different shapes, such that when the user operates the mouse, the angle for the wrist joint to extend naturally is enlarged. Thus, the problems of wrist joint pain, radial styloiditis, and carpal tunnel syndrome are avoided. However, this kind of mouse pad is also placed on a table, and the scapula, shoulder, elbow, wrist, and a part of the finger joints have to exert forces, thus, the muscles participating in the motions are still continuously kept in the contracted state. From the anatomical point of view, the distal and local muscles cannot be truly relaxed, if the proximal muscles are not relaxed. Therefore, this mouse pad structure cannot fully relax the entire skeletons, joints, and muscular system of the user's upper body, which does not really solve the problems.
A carrying board under a table for placing the keyboard and the mouse is also available on market in this field, which can be drawn out from the table. When a user sits in front of the table to operate the computer, the carrying board is drawn out to above the legs. Thus, the height of the palms and elbows is lowered, and the contracted state of the aforementioned muscles is relieved. However, the height of the carrying board is not low enough to allow the palms or arms to naturally drop down, so the elbow, wrist, and a part of the finger joints have to exert forces, which makes the muscles of these parts continuously maintain in the contracted state. After a long use of the keyboard and mouse, diseases of the elbow, wrist, and a part of the finger joints occur. Therefore, the carrying board also does not really solve the problems.

SUMMARY OF THE INVENTION

In view of the above problem, an object of the present invention is to provide an article of furniture for placing an electronic device. The furniture for placing an electronic device provides a support board, which allows a user to control the electronic device with the hand at a position where the hand naturally drop down, such that the user's arm has a natural dropping motion, and muscles and joints are kept in a relaxed state. Thus, the ergonomic requirements are met, and the user's hands can operate the electronic device for a long time without making the hand hurt.
Therefore, to achieve the aforementioned object, the present invention provides an article of furniture for placing an electronic device, which provides a carrying board for placing the electronic device at the position of palms where a user's hands naturally drops down, such that the user operates the electronic device with the hand at the position where the hand naturally drops down. The present invention provides a plurality of embodiments to achieve the above object.
Therefore, as for a user who must operate an electronic device with the same posture for a long time, the present invention guides the user to naturally drop down the shoulders and keep the elbows higher than the wrists when operating the electronic device. When a user operates an electronic device, whether in a sitting posture or a standing posture, if the arms are kept at a normal physiological position, i.e., the shoulders and elbows naturally drop down, and the wrists are lower than the elbow joints, the user only needs to flex the thumb and adduct the thumb, and flex the finger tips to operate the electronic device. Thus, the motions for the scapulas, shoulders, elbows, wrists, and a part of the finger joints to exert forces are omitted, so that the muscles that are originally participated in the motions when the hands are raised are no longer continuously kept in the contracted state as the hands naturally drop down. Thus, the risks of neck rigidity, pain of the upper back, pains of the shoulder, elbow, and wrist joints, De Quervain's disease, and even carpal tunnel syndrome are relatively avoided.
However, it is known that a lot of money is spent on the treatment of musculoskeletal pains all over the world, and if certain surgeries and long-time recovery are taken into consideration, the cost will be even unimaginable. Therefore, the present invention allows a user who has to maintain the same posture for a long time to change the method of operating the electronic device in an ergonomic manner, so as to relieve the diseases of joints and muscles caused by wrong postures. Thus, the present invention helps users to maintain the health and eliminate the sores and pains, and helps employers to enhance the employees' working efficiency and thereby creating more benefits. As for the features and examples of the present invention, the preferred embodiment will be illustrated below in detail with reference to the drawings.
Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to an article of furniture for placing an electronic device, which includes a furniture component and a support board. The support board is disposed on the furniture component (e.g., a desk or a chair), and located at a position where the user's hands naturally drop down. Thus, when the user operates the electronic device on the support board, the arms naturally drop down, so as to operate the electronic device in a posture that satisfies the ergonomic principle. Therefore, the problems of pains of wrist joints, elbow joints, or shoulder joints, and sores and pains of the muscles caused by contracted arm muscles due to the arms being placed on the table for a long time are avoided. Therefore, the correct posture for operating the electronic device is to maintain the arms to naturally drop down, which enables the muscles of the upper body and the arm muscles to not exert forces, such that shoulder joints, elbow joints, scapulas, and wrist joints are kept relaxed. When the user uses a mouse, the clicking operations can be achieved only through muscles of fingers, and the use of other muscles of the arms is substantially reduced. As computers are extensively used nowadays, and a mouse is often used when operating the computer, the mouse is taken as an example to illustrate the present invention in this embodiment. Therefore, the present invention provides an article of furniture for placing an electronic device, which provides a support surface for placing a mouse at a position where the user's hand naturally drops down when the user is sitting or standing, so as to enable the user to operate the mouse with the hand naturally dropping down. The present invention provides a plurality of embodiments to achieve the object. FIGS. 2, 3A, and 3B are respectively a combined view, an unfolded stereogram of a support board, and a folded schematic view of a support board according to the present invention. Referring to FIGS. 2, 3A, and 3B, a fixing board 300 and a carrying board 310 are both board bodies. The fixing board 300 is fixed on the furniture component, which is a table 390 in this embodiment, and the carrying board 310 is used for placing a mouse 930, such that the mouse 930 is operated on the carrying board 310. Furthermore, the support board in this embodiment is still folded, which is convenient for the storage, as shown in FIG. 3B. A connecting rod 330 is used to connect the fixing board 300 with the carrying board 310. One end of the connecting rod 330 is pivoted on one side of the fixing board 300, and the other end of the connecting rod 330 is pivoted on one side of the carrying board 310, such that the fixing board 300 and the carrying board 310 can be folded together for storage, or can be unfolded relative to each other for being used. Moreover, to maintain the open state when the fixing board 300 and the carrying board 310 are unfolded relative to each other, a first supporting rod 350 and a second supporting rod 360 are used. One end of the first supporting rod 350 is movably snapped on the fixing board 310, and the other end is pivoted on the connecting rod 330, so that the connecting rod 330 and the fixing board 300 are supported at a certain angle. One end of the second supporting rod 360 is movably snapped to the carrying board 310, and the other end is pivoted on the connecting rod 330, so that the connecting rod 330 and the carrying board 310 are also supported at a certain angle. Therefore, the fixing board 300 and the carrying board 310 are maintained at an open state through the first supporting rod 350 and the second supporting rod 360, so that when the user holds the mouse 930 with a palm 910, the mouse 930 is placed on the carrying board 310 for being operated, and at this time, an arm 900 and the palm 910 are maintained to be naturally dropped down.
When the support board is not used, the first supporting rod 350 and the second supporting rod 360 slide relative to the fixing board 300 and the carrying board 310 respectively, such that the fixing board 300 and the carrying board 310 are folded relative to each other, as shown in FIG. 3B.
To enable the first supporting rod 350 and the second supporting rod 360 to be movably snapped to the fixing board 300 and the carrying board 310 respectively, a trough 370 is arranged on one side of each of the fixing board 300 and the carrying board 310, and a plurality of notches 371 is further arranged on the peripheral edge of each of the troughs 370, such that one end of the first supporting rod 350 slides in the trough 370 of the fixing board 300, and it is snapped to one of the plurality of notches 371 at a certain position, so as to adjust the angle between the fixing board 300 and the connecting rod 330. Similarly, one end of the second supporting rod 360 also slides in the trough 370 of the carrying board 310, and it is snapped to one of the plurality of notches 371 at a certain position, so as to adjust the angle between the carrying board 310 and the connecting rod 330. Therefore, by adjusting the angle between the fixing board 300 and the connecting rod 330 and adjusting the angle between the carrying board 310 and the connecting rod 330, the height between the fixing board 300 and the carrying board 310 can be adjusted. Since the positions reached when different users' hands drop down are different in height, the height between the fixing board 300 and the carrying board 310 is adjusted, so as to cater to different users.
FIGS. 4 and 5 are respectively a schematic view of a second embodiment of the present invention and a schematic view of the support board. Referring to FIGS. 4 and 5, the support board of the furniture for placing an electronic device in this embodiment uses a box-shaped body 500 to be clamped to the furniture component. The furniture component can be a plate 570 of the table that is screwed to one side of the box-shaped body 500 with a bolt 510. The bolt 510 is fastened against the plate 570, such that the box-shaped body 500 is fixed to the plate 570. One end of a connecting rod 530 is connected to one side of the box-shaped body 500 where the bolt 510 is fastened, and the other end of the connecting rod 530 is connected to a carrying board 550. The carrying board 550 is also located at the position where the user's palm 910 naturally drops down, such that when the user holds the mouse 930 with the palm 910, the mouse 930 is placed on the carrying board 550 for being operated. Thus, the arm 900 and the palm 910 are kept to naturally drop down, which meets the ergonomic requirements, so as to avoid the hand from being hurt when using the mouse 930 for a long time.
FIG. 6 is a combined schematic view of a third embodiment of the present invention. Referring to FIG. 6, the furniture component is a desk 700. A support board 710 is pivoted on the desk 700, and the support board 710 is located at the position where the user's hands naturally drop down. When the user holds the mouse 930 with the palm 910, and the mouse 930 is placed on the support board 710 for being used, the user's arm 900 and palm 910 are in a posture that meets the ergonomic requirements. Therefore, though the user operates the mouse 930 for a long time, the hand or shoulder will not hurt. To receive the support board 710 into the desk 700, an accommodation chute 701 is disposed on a rotating path of the desk 700 relative to the support board 710, so as to receive the support board 710 into the accommodation chute 701. When the support board 710 is needed to be used, it is drawn out.
FIGS. 7A and 7B are respectively a combined schematic view of a fourth embodiment of the present invention and a top view of a chair. The furniture component is a chair 730, and a support board 750 is pivoted on the chair 730. The support board 750 is located at the position where the user's hands naturally drop down. When the user holds the mouse 930 with the palm 910, and the mouse 930 is placed on the support board for being used, the user's arm 900 and palm 910 are in a posture that meets the ergonomic requirements. Therefore, though the user operates the mouse 930 for a long time, the hand or shoulder will not hurt.
The support board 710 also can be received under the chair 730. When the support board 710 is not used, it is rotated to a position under the chair 730. When the support board 710 is needed to be used, it is pulled out again.
FIGS. 8A and 8B are respectively a combined schematic view and a side view of a fifth embodiment of the present invention. Referring to FIGS. 8A and 8B, a fixing member 800 is clamped on the furniture component. In this embodiment, the furniture component is a table 390, and the carrying board 310 is used to place the mouse 930, such that the mouse 930 is operated on the carrying board 310. In this embodiment, the support board is kept in a folded state, which is convenient for the storage, as shown in FIG. 8C. Therefore, the connecting rod 330 is required for connecting the fixing member 800 with the carrying board 310. One end of the connecting rod 330 is pivoted on one side of the fixing board 300, and the other end is pivoted on one side of the carrying board 310, such that the fixing board 300 and the carrying board 310 are folded relative to each other for storage, or they are unfolded relative to each other for being used. In addition, to maintain the open state of the fixing member 800 and the carrying board 310 when they are unfolded relative to each other, the first supporting rod 350 and the second supporting rod 360 are used. One end of the first supporting rod 350 is movably snapped to the fixing board 300, and the other end is pivoted on the connecting rod 330, such that the connecting rod 330 and the fixing board 300 are supported at a certain angle. One end of the second supporting rod 360 is movably snapped to the carrying board 310, and the other end is pivoted on the connecting rod 330, such that the connecting rod 330 and the carrying board 310 are also supported at a certain angle. Therefore, the fixing board 300 and the carrying board 310 maintain an open state through the first supporting rod 350 and the second supporting rod 360. When the user holds the mouse 930 with the palm 910, the mouse 930 is placed on the carrying board 310 for being operated, the arm 900 and the palm 910 are kept to naturally drop down.
When the support board is not used, the first supporting rod 350 and the second supporting rod 360 slide relative to the fixing board 300 and the carrying board 310 respectively, such that the fixing board 300 and the carrying board 310 are folded relative to each other, as shown in FIG. 8C.
To fix the fixing member 800 on the table 390, the fixing member 800 includes a first rod 810, a second rod 830, and a clamping piece 850. One end of the first rod 810 is pivoted on the connecting rod 330, and the second rod 830 extends from the end of the first rod 810 pivoted on the connecting rod. The clamping piece 850 is fixed to the second rod 830, which is formed by a piece bent into a horseshoe shape, so as to form a mutual clamping force. Therefore, the clamping piece 850 has an elastic force for clamping the table 390. To enhance the rigidity of the first rod 810 and the second rod 830, a plurality of reinforcing rods 870 are connected between the first rod 810 and the second rod 830. Two ends of each of the reinforcing rods 870 are connected to the first rod 810 and the second rod 830 respectively, so as to maintain the positions of the first rod 810 and the second rod 830, thereby preventing the deformation of the first rod 810 and the second rod 830 caused by external forces.
To enable the first supporting rod 350 and the second supporting rod 360 to be movably snapped to the fixing member 800 and the carrying board 310 respectively, the trough 370 is arranged on one side of each of the first rod 810 of the fixing member 800 and the carrying board 310, and a plurality of notches 371 is arranged on the peripheral edge of each of the troughs 370, such that one end of the first supporting rod 350 slides in the trough 370 of the fixing board 300, and it is snapped to one of the plurality of notches 371 at a certain position, so as to adjust the angle between the first rod 810 of the fixing member 800 and the connecting rod 330. Similarly, one end of the second supporting rod 360 also slides in the trough 370 of the carrying board 310, and it is snapped to one of the plurality of notches 371 at a certain position, so as to adjust the angle between the carrying board 310 and the connecting rod 330. Therefore, by adjusting the angle between the first rod 810 of the fixing member 800 and the connecting rod 330 and adjusting the angle between the carrying board 310 and the connecting rod 330, the height between the fixing member 800 and the carrying board 310 can be adjusted. Since the positions reached where different users' hands drop down are different in height, the height between the fixing member 800 and the carrying board 310 is adjusted, so as to cater to different users. Therefore, in the aforementioned embodiments, when operating the mouse, the user's hands are kept in a natural state, i.e., the state that both hands naturally drop down when the user is standing, and the mouse is operated when both hands naturally drop down. When the mouse is not moved, the clicking operations are achieved only through finger muscles, and the other parts are kept in the relaxed state. When the mouse is moved, only the muscles of the hands are slightly used, which will soon get relaxed again when the mouse is not moved. Thus, the hands will not be tired or hurt even if operating the mouse for a long time.
The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
