Description

"IMPROVEMENT IN WORKSTATION FOR PERSONAL COMPUTER"

The present invention refers to an improvement developed in workstation intended to support personal computer, as desktop, notebook or laptop, which is equipped with means for adjustment of the height, inclination and the distance from the user to the computer.

The office tables, also known as desks, were, historically, conceived for the act of writing, where their dimensions have been defined to meet the ergonomic demands of this type of movement. More recently, with the advent of the personal computers, these tables underwent some modifications for the purpose of supporting the keyboard at an adequate height. Initially, auxiliary tables were designed with trimmed pads for support only of the keyboard and equipped with devices for the height adjustment. More recently tables with lower pad were designed for a better adaptation to the ideal height of the keyboard and of the act of writing or with small sliding pads, positioned under the main pad, for support only of the keyboard.

However, these known furnitures still present the following inconveniences:

- they do not present possibility of adjustment of the inclination of the keyboard pad;

- they are not adequate for the support of notebooks and laptops;

- they have large dimensions, which are not adequate to small spaces like residential quarters and rooms;

- the positioning of the notebook directly over the table, on top of the legs or on other inadequate places, provokes inadequate posture of the cervical column, which can cause repetitive effort lesions (REL) and/or lumbar pains, aggravated by the long period that the user stays operating the computer.

It is, therefore, the objective of the present invention an improved workstation that enables to maintain the notebook or alike in an adequate position for the sight and for the movement of the wrists in typing, minimizing the harmful effect to the cervical column. This is achieved through a furniture that includes a central column that supports an articulated arm with adjustment in the height and in the inclination of the support pad of the notebook. A pad for the mouse is set on the articulated arm, accompanied with the adjustment of the distance and enabling even its rotation. A support arm of an auxiliary table fixed on the central column completes the workstation.

The workstation of the invention presents the following advantages over the other known furnitures for support of personal computers:

- it has means for adjustment of the height, inclination and distance from the support of the notebook, meeting the anthropometric diversities;

- the mouse support is linked to the support arm of the support of the notebook, accompanied with its movements, aside from even allowing an adjustment in its rotation;

- it is light, of reduced dimensions and totally dismountable, allowing its transport with ease;

- it can be used independently or, due to its reduced dimensions, associated to a conventional table, acting as table specific for the notebook; - it has an auxiliary table and support for accessories, increasing its versatility.

These and other advantages of the present invention will become more evident through the following detailed description, which is based on the enclosed designs, listed below, which illustrate a preferential concretization of the workstation, which must not be considered limiting to the invention: Figure 1 - perspective of the workstation improved by the invention;

Figures 1 to 7 illustrate the improvement developed in workstation that includes a central column (1) that is supported inferiorly by three horizontal legs (2) with shoes at the end (3). At intermediate height of the column (1) a fixed lower ring (4) is positioned. From an intermediate ring (5) extends an arm (7) that supports a pad (8), which serves as auxiliary table. From the upper ring (6) a horizontal arm (9) is projected, in whose extremity a second arm segment (10) is articulated that supports a pad for notebook (11). On the arm (9) the support (12) of a mouse pad (13) rests. Preferably, the mouse pad (13) is fixed on its support (12) through a vertical pin (14), allowing its rotation, such that it accompanies the angle adjustment of the notebook pad (11).

Also preferably, the arm segment (10) has two orthogonal beams

(15) with a horizontal axle (16), where a support (17) reclines jointly with the pad (11 ), thus allowing the inclination of the notebook.

One of the extremities of the axle (16) can present a rapid coupling system (18) that allows the immediate release of the support (17) for rotation on the beams of the arm (15). A vertical rod with upper fold (19) slides on the arm (7) of the auxiliary table (8), which can be used for hanging accessories, such as penholders, block pads and mobile phones, among others.

The intermediate (5) and upper (6) rings can rotate on the central column (1) supported by the fixed ring (4), allowing an angular movement of the auxiliary table (8) and of the arm (9), bringing with it the pad of the notebook (11) and of the mouse (13).

The upper ring (6) can present a screw (20) that allows its setting at any height, no longer needing to be rested on the fixed ring (4). Figures 8 to 13 illustrate a second evolution of the workstation that also includes a central column (1) where a fixed lower ring (4) is positioned, an intermediate ring (5) and an upper ring (6). From the intermediate ring (5) extends an arm (7) that supports an auxiliary table pad (8). From the upper ring (6) a horizontal arm (9) is projected, in whose extremity a second arm segment (10) is to be linked that supports a pad for notebook (11). A vertical rod with upper fold (19) slides vertically in the arm (7) of the auxiliary table (8) that is to be useful for hanging accessories, such as penholders, block pad and mobile phone, among others.

A first evolution of the workstation consists in the fact that the column (1) comes to present, besides the three horizontal legs (2), a fourth leg (2^J), which are all equipped with wheels at the ends (3'). Over the fourth leg (2') an item holder is set (20).

A second evolution of the workstation is that the arm segment (10) has two orthogonal beams (15) with coaxial horizontal screws (16'), where a support (17) reclines, which is common to the pad (11), intended for the inclination of the notebook. One of the screws (16') presents a rapid coupling system (18) that allows the immediate release of the support (17) for rotation on the orthogonal beams (15) of the arm (10). On the opposite screw (16') a support (12') is fixed in whose extremity the mouse table (13) is positioned. The mouse table (13) is can be rotated on the support (12') through a screw with handle (14').

Figures 14 to 18 illustrate a second constructive variant of the workstation that also includes a central column (1) where a ring (6") is positioned from which a horizontal arm is projected, however long, straight and unarticulated (9') that supports a pad for the notebook (11). The column (1) presents three horizontal legs (2) that are equipped with wheels at the end (3"). On a lower horizontal support (21) positioned together at the base of the column (1) an item holder (20) is fixed. A second column (22), of reduced diameter, is laid out in a parallel way and next to the column (1) and is intended to limit the rotation of the arm (9"), whose ring (6") presents stop pins (23). Without this limiter, in case the arm (9") is able to rotate 180°, the workstation could become unstable. At the extremity of the long arm (9") there is a handle (24) that releases the rotation of the notebook pad (11). The rotation of this handle (24) also makes a screw (25) to advance that provokes the inclination of the notebook pad (11 ).

Figures 19 to 24 illustrate a third variant of the workstation, with special application for desktop computers. This workstation also includes a central column (1) where a fixed lower ring (4) is positioned, an intermediate ring (5) and an upper ring (6). From the intermediate ring (5) an arm (7"') extends, however straight, which supports an auxiliary table pad (8). From the upper ring (6) a horizontal arm (9) is projected, in whose extremity a second arm segment (10) is to be linked, followed by a third arm segment (10'") that supports a long pad (11'") for keyboard and mouse.

Also in this variant, the column (1) comes to present, besides the three horizontal legs (2), a fourth leg (2'"), where all are equipped with wheels at the end (3'"). Over the fourth leg (2'") a CPU compartment (20'") is fixed.

Further in this variant, the segment of the extreme arm (10'") has two orthogonal beams (15) with coaxial horizontal screws (16'"), where a support (17) reclines, for inclination of the pad (11'"). One of the screws (16'") presents a rapid coupling system (18) that allows the immediate release of the support (17) for rotation of the beams of the arm (15).

On the column (1) a fourth ring (26) is prepared with a horizontal arm (9'"), where two arm segments (10'") are to be linked, in whose extreme a "U" support (27) is joined. Underneath the upper ring (6) and the fourth ring (26) fixed rings (4'") are positioned for safety of the workstation.

The support (28) of the LCD monitor is linked, according to a horizontal axle, on the "U" support (27), through screws (29). The "U" support (27), in turn, rotates, also according to a horizontal axle (30), however orthogonal to the other axle, in the arm segment (10'"), causing the position adjustment of the LCD monitor to be obtained according to two degrees of freedom, namely, rotation and inclination.

Figures 25 to 30 illustrate a fourth constructive variant of the workstation that also includes a central column (1) where a ring (6") is positioned from which a horizontal arm is projected, however long, straight and unarticulated (9") that support a pad for notebook (11). The column (1) presents three horizontal legs (2) that are equipped with wheels at the end (3"). A slot (31) is executed at the column (1) and is intended to impede the rotation of the arm (9"), whose ring (6") presents a screw (23'). At the extremity of the long arm (9") a trellis is positioned formed by two supports (32) in whose interior acts a sphere (33) linked to the pad (11) that allows its spatial inclination. A handle (34) drives a screw that releases the rotation of the sphere (33) and the inclination of the notebook pad (11).
