Description

Ergonomic functional table with adjustable height and angle

Technical Field

The present invention relates to an ergonomic functional table that can be adjusted in height and angle, and more particularly, to a functional table that a user can adjust an upper plate of the table to a desired height and angle.

Background

In general, a table used in a home, a school, and an office is generally formed of an upper plate, which is generally formed of a firm wooden material, and a bracket, which stably supports the upper plate, and is used by placing various items such as books, desktops, telephones, documents, office supplies, and the like on the upper plate.

On the other hand, in the case of conventional tables, since the specifications are approximately fixed, in the case of tables used by children at home in a long-term environment, tables having a height that does not match the body condition of the children are often used, and the use of tables that do not match the body condition involves a risk of a habit that the children form an unfavorable posture in the long-term environment, and there is an increasing demand for body condition-customized tables for children that deviate from the standardized tables.

In order to solve the problems of the standardized table, korean patent laid-open publication No. 10-1564363 (2015, 10/23) discloses a table having a structure for adjusting the height and angle of an upper plate, wherein lifting units are provided inside both sides of a leg of the table, and the lifting units on both sides are configured to be operated in conjunction with each other, so that convenience in use and a stable lifting effect can be obtained, i.e., when anyone easily adjusts the lever from one side, the upper plate can be lifted and lowered by the operation of the conjunction.

However, in the above-described conventional art, since the angle and height adjusting means are separately formed and the adjusting handles are located at different portions from each other, it is difficult for a user to accurately adjust a desired height and angle.

Further, in order to adjust the height, the lever needs to be rotated repeatedly, and in order to sufficiently fix the angle adjustment, a large force is required to press the lever, which causes a problem that it is difficult for young children to operate.

Referring to fig. 8 and 9, the operation of the angle adjusting unit 300 is examined. First, fig. 8 and 9 illustrate the right angle adjustment unit 300 of the functional table 500, and the left angle adjustment unit 300 operates on the same principle.

Fig. 8 shows a state before the angle of the upper plate is adjusted, in which the cam link 322 is parallel to the angle adjustment lever 311b, the other end of the connection shaft 3223 presses the cam bush 3232 in a direction in which the elastic pressing portion 323 is compressed, and the elastic pressing portion 323 is pressed against the inclined bracket 321 and functions as a stopper, thereby fixing the main upper plate 111.

In the above state, when the user pulls the angle adjustment lever 312b forward, one end of the cam link 3221 rotates in the forward direction according to the principle of leverage about the rotation pin, and one end of the cam link 3221 is connected to the angle adjustment lever 312 b.

At this time, the other end portion of the connection link 3222 connected to the cam link 3221 is formed to be curved to function as a cam, and when the cam link 3221 is rotated, the other end portion of the connection link 3223 moves the cam bush 3232 in a direction in which the elastic pressing portion 323 is loosened in conjunction with the rotation, thereby loosening the elastic pressing portion 323.

As described above, when the elastic pressing portion 323 is loosened, the tilt bracket 321 is slidably tilted as the elastic bracket pressing the tilt bracket 321 is loosened, and the tilt bracket 321 can adjust the angle of the main upper plate 111 using the cam shaft 324 penetrating into the bracket hole as a rotation shaft.

On the other hand, although not shown in the drawings, the angle adjusting means 300 can adjust the angle by rotating the main upper plate 111 in the front-rear direction with respect to the horizontal rotation axis as described above, and can also adjust the position of the main upper plate 111 at various angles by rotating the main upper plate 111 in the left-right direction with respect to the plumb direction rotation axis. Therefore, the angle adjusting unit 300 may adjust the main upper plate 111 to various angles by applying a multi-axis movable rotary joint or the like, unlike the angle adjusting unit 320.

The height adjusting unit 400 functions to adjust the height of the main upper plate 111, and includes a horizontal support bar 410 and a height adjusting part 420. The horizontal support rods 410 are fixedly coupled to the inner sides of the pair of first links 221 having opposite ends. The horizontal support bar 410 may be a hollow tube, but any structure may be used as long as the above object can be achieved by the preferred embodiment.

One side of the height adjusting part 420 is rotatably coupled to a support rod coupling part 411, the support rod coupling part 411 is coupled to a central part of the horizontal support rod 410, and the other side of the height adjusting part 420 is fixedly coupled to the back panel 120 of the table main body 100 through a coupling part 430. The height adjusting part 420 moves the horizontal support rod 410 in the vertical direction by stretching and contracting, and the upper plate part 110 moves in the vertical direction as the horizontal support rod 410 moves in the vertical direction, thereby adjusting the height.

For example, the height adjusting part 420 is basically in a contracted state at ordinary times, the main upper plate 111 is fixed at a predetermined height, and when a user pulls the height adjusting rod 312a provided at the lower portion of the front surface of the main upper plate 111 forward, the wire 313b having one end connected to the height adjusting rod 312a is pulled forward in conjunction with the operation direction of the height adjusting rod 312a, and the wire 313b having the other side connected to the height adjusting part 420 loosens the tension of the height adjusting part 420, so that the height of the main upper plate 111 can be adjusted.

The height adjusting part 420 may be an elastic member that is compressed or stretched according to a change in height of the upper plate part 110, but any structure may be used as long as the above object can be achieved by the preferred embodiment.

On the other hand, although not shown, the height adjusting part 420 includes a height fixing part which is fixed after the upper plate part 110 is installed at a height required by a user, and various structures such as a locking part of a known gas spring and a locking pin can be applied to the height fixing part, and detailed description thereof will be omitted.

On the other hand, although not shown in the drawings, the functional table 500 may further include a bookcase and an illumination unit provided above the upper plate portion 110, and the illumination unit may be provided in the bookcase to improve a learning atmosphere of a user. The lighting unit adjusts color temperature in three steps as follows, corresponding to the learning fields of users such as the language field, the search field, and the creative field: 5000K color temperature for assisting memory improvement, 6500K color temperature for assisting logic ability improvement, and 3500K color temperature for assisting imagination stimulation.

In addition, when the main upper plate 111 is lowered downward, the functional table 500 may be provided with a front cover in a space between the main upper plate 111 and the auxiliary upper plate 112 on the front surface of the user, so that a photograph or a note may be attached through the front cover, thereby improving space utilization.

According to the above, the functional table 500 can adjust the height and angle of the table independently and variously according to the physical condition of the user and the kind of work activities through the angle adjusting unit 300 and the height adjusting unit 400 by ergonomics, and thus can be adjusted to various forms including various heights and angles according to the selection of the user, and the operation for adjusting the heights and angles is simple and convenient.

While the present invention has been described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
