According to the International Patent Classification (IPC), the symbols are:

Technical Issue

How to solve the technical issue concerning movability of a desktop computer by joining its basic components (the tower, monitor, keyboard and mouse) with the construction enabling use of the computer in sitting, standing and lying position.

BACKGROUND ART

Movable ergonomic carrier for desktop computers enables the user to choose between using the computer while sitting, standing or lying down, as well as simply relocating the computer in the room or from one room to another.

Known solutions dealing with this technical issue are those by company Ergoquest from the United States of America.

Near the top of the 185 cm high column, which is fastened to the pedestal with 4 castors in the shape of the Cyrillic letter P (Π), and particularly in the middle of the bracket joining together two parallel brackets, there is the joint which is followed by double joints, so called the mount arm, which can be rotated around a horizontal and vertical line. Near the top of the mount arm there is the monitor fastening and the extension ending with the surface fastened to it for holding the keyboard and mouse. Thus, monitor, keyboard and mouse are carried by the same joint. The shortcoming of this solution is that the position of the monitor, in terms of height and distance from the user, also determines the position of the keyboard and mouse and vice versa.

There is another variant of the solution where the keyboard and mouse are on the special mount arm located in the middle or the top of the main column bearing the mount arm of the monitor. Common shortcomings of both first and second option are as follows:1. Dependence to use the special, ergonomic chair. Since the use of keyboard and mouse requires the surface underneath to be stable, so as to prevent its vertical movement during use, and in these cases the surface is fastened to the mount arm which is both vertically and horizontally rotatable, the stability of the surface needs to be provided somehow. The author solved this problem by also envisaging as the mandatory accessory of the carrier, the ergonomic chair with arm rests on which the surface for the keyboard and mouse rests. The ergonomic chair is electrically powered and can be placed in seating and lying position. It is positioned between parallel brackets making the pedestal, so that its flank is parallel to the transverse bracket joining the parallel brackets.2. The keyboard and mouse cannot be used in standing position due to a lack of stable surface.3. The computer tower stands on the transverse bracket of the pedestal so that the user of the computer in the ergonomic chair is not adequately distant, especially in lying position, from negative electromagnetic radiation emanating from certain components placed in the tower.4. The dimensions of the carrier itself. The parallel brackets of the pedestal have sufficient length to provide stability to the entire carrier because the column itself is quite high. However, that makes use of the carrier without the ergonomic chair, on a common bed, difficult as it makes too much distance between the carrier column and the bed. Furthermore, it also makes using the carrier difficult at ordinary table or desk. The desk would have to be placed between the parallel brackets of the pedestal so that one of the brackets would interfere with placing and using chair.Although positioned on castors, the carrier is not easily moved in the room or from one room to another due to its size, especially if a desktop computer is placed on it. Furthermore, when the computer is out of use and when it needs to be put out of the way, the carrier still takes up a lot of space.Certain elements of the carrier have such size that even when the carrier is disassembled in order to be packed and transported, it still takes up a lot of space.5. The price of one of the carriers together with the ergonomic chair is 10 to 15 times greater than the production price of the invention.

DISCLOSURE OF INVENTION

The invention represents metal construction enabling the user to choose between using the computer while sitting, standing or lying down and particularly in sitting and lying position using any type of chair or bed, without making it necessary to use special ergonomic chairs or beds which pose a condition for efficient use of the carriers described in the Technical State. Furthermore, it enables the user to relocate the computer inside the room or from one room to another in a quick and simple way.

The advantage of the invention is in its construction because joints with pipe carriers of the keyboard and mouse can only be rotated around a horizontal but not vertical line, thus providing stability necessary for their efficient use in whatever position the user may be. Furthermore, there can also be adjusted the height of the bars carrying joints which include the pipe carriers of the monitor, keyboard and mouse so they are not always extended maximally, but only when it is necessary. Furthermore, they can also be drawn out, i.e. made further from the flank of the pedestal to the specific length of the two flank castors being on the same side. They will be drawn out only as far as it is necessary to provide stability to the entire carrier but not always all the way out. Because of the places of the pipe carriers of the monitor, keyboard and mouse, which are always in the front of the pedestal, to the right or left of the tower front, the invention may be placed so that the user, whether he be sitting, standing or lying down, is at safe distance from harmful electromagnetic radiation emitted by certain components inside the computer tower.

Because of the smaller size of its constituent elements, the invention can be easily disassembled and packed for transport. It is lighter, takes up less space, and its rectangular pedestal and rectangular frame make it easy to move inside the room or from one room to another.

BEST MODE FOR CARRYING OUT OF THE INVENTION

The invention is a construction made of the following types of metal elements:

Pipes, bars, L-profiles, boxes, guides and fastening elements (bolts). In addition to them, there are also 4 castors, plywood as the pedestal for the mouse and the weight of flat bar rectangular frame filled with concrete.

The pedestal83of the invention is rectangular, its shorter sides being 30 cm long each and longer sides being 48 long each. The shorter sides are made of boxes1and2each being 30 cm long, 4 cm high and 4.5 cm wide. Their inside dimensions are: 30 cm long, 3.2 cm high and 4.2 cm wide each. The longer sides3and4are made of L-profile each being 39 cm long, 4 cm high and 4 cm wide. The sides are welded. The tops of each of the boxes1and2are open just on one side and particularly those that emerge on the same flank of the pedestal83, and so they have the boxes5and6drawn into them, each being 29 cm long, 3 cm high and 4 cm wide, whose upper top surfaces, each being 2 cm long and 4 cm wide, have welded flat bars each being 7.5 cm long and 4 cm wide, representing the carriers7and8of the castors, so that when the boxes5and6are fully drawn in the boxes1and2, the carriers7and8of the castors are aligned with the upper surface of the pedestal83. The castors9and10which are revolving, are fastened for the carriers7and8of the castors with the elements85and87for fastening. The box6is fastened in the appropriate position with the element11for fastening. The box5is fastened in the same way. On the opposite flank of the pedestal83, the carriers12and13of the castors each 7.5 cm long and 4 cm wide are welded to the ends of the pedestal83perpendicularly with their shorter sides and so they are aligned with the upper edge of the pedestal83. The castors14and15which are revolving are fastened to the carriers12and13of the castors with the elements84and86for fastening. The upper surface of the pedestal83has two flat bars27and28welded, each being 22 cm long and 4 cm wide. The flat bar27is welded to the side of the box1and in front and back part to the L-profiles3and4. The other flat bar28is laterally welded to the box2, while its front and back are welded to the L-profiles3and4.

At the front part of the pedestal83, places16and17are welded to mount the weight, each being 3 cm long, 2 cm wide and 4 mm high, and those same places are also in the back of the pedestal83. The weight18, dimensions: 30 cm×16 cm×4 cm, weighing 5 kg is aligned with the pedestal83when mounted to it. Its purpose is to provide further stability to the movable ergonomic carrier of the desktop computer and serve as the pedestal to which the sockets of extension cable are fastened, providing the computer with power.

The upper surface of the pedestal83has one 4 cm long sleeve19,20,21,22in all four corners. They have pipes23,24,25,26, each being 48 cm long, pulled into them and fastened with the elements29,30,31,32for fastening. The pipe tops23,24,25,26have, in the length of their sleeve, pulled onto them rectangular frame33consisting of pipes, two of which are 38 cm long and the other two 25 cm long, whose ends are welded to four sleeves34,35,36,37, each being 3 cm long. The frame is fastened to the pipes through the elements38,39,40,41for fastening, but these elements go through the pipes and only on one side.

The pipes23and24have the bars42and43pulled into them, each being 2.2 cm in diameter. They are the same length as the pipes, but have the lower parts of the joints44and45welded to their tops, as the extensions. The bars23and24can be vertically pulled in and out to the length of the pipes in which they are placed and fastened in appropriate position with the elements38and39for fastening. The upper part of the joint44has the bar46, being 2.2 cm in diameter and 30 cm long, welded to it at the angle of 45° up to the place where it is angled and is further perpendicular to the bar42. In the length of 20 cm, the bar46is pulled into the pipe47being 27 long, the end of which has the lower part of the joint48welded to it perpendicularly. The pipe47is fastened to the bar46with the element49for fastening. The upper part of the joint48has one end of the pipe50perpendicularly welded to it. The length of the pipe50is 33 cm. The pipe50has on the other end pulled into it to the length of 10 cm, one arm of the bar51bent perpendicularly, while the other arm to the length of 11 cm goes into the so called the mount52arm. The bar51is fastened to the mount52arm with the element53for fastening. The mount52arm is designed to have the computer monitor fastened to it which allows monitor rotation around a horizontal and vertical line as well as circular motion. Furthermore, it also provides height adjustment of the monitor in the range of 0° to 90°.

The upper half of the joint45has one end of the pipe53welded to it perpendicularly. The pipe53is 36 cm long. The other end of the pipe53is welded, also perpendicularly, to the lower part of the joint54. The upper part of the joint54has one end of the pipe55welded to it. The pipe55is 33 cm long. The other end of the pipe55has pulled into it the bar56, 2.2 cm in diameter and 5 cm long. The top of the bar56has the lower part of the joint57perpendicularly welded to it. The bar56is fastened to the pipe55with the element58for fastening. The upper half of the joint57has sleeve59, 4 cm long, welded to it. The sleeve59is perpendicularly welded to the top of the upper half of the joint57in the middle of its body. The sleeve59has pipe60pulled through it, which is fastened to it with the element61for fastening. The pipe60is pulled through two more sleeves62and63, each being 3 cm long, which have welded to them the guides64and65of the keyboard carrier, each being 8 cm long and 3 cm wide. The sleeves62and63with the guides64and65of the keyboard carrier are fastened to the pipe60with the elements66and67for fastening. The guides64and65of the keyboard carrier have pulled into them the keyboard68and69carriers, each being 18 cm long, plus the curved lower ends being 1 cm long and 2.5 cm wide. The keyboard68and69carriers are fastened to the guides64and65of the keyboard carrier with the elements70and71for fastening. The upper ends of the keyboard68and69carriers have pulled onto them the elements72and73for the keyboard fastening, each being 2 cm long and 3 cm wide, and their parts 3 cm long and 2 cm wide which are perpendicular and whose purpose is to rest on the keyboard. The elements72and73for the keyboard fastening are fastened to the carriers68and69of the keyboard with the elements74and75for fastening. The other end of the pipe60has the bar76pulled into it. The bar76is 20 cm long and 1.6 cm in diameter. The bar has perpendicularly welded to it the top of the pipe77, 11.5 cm in length with the outer diameter being 1.6 cm and inner being 1.3 cm. The bar76is fastened to the pipe60it goes into with the element78for fastening. The bar79bearing the pedestal for the mouse, being 11.5 cm long and 1.2 cm in diameter is pulled into the pipe77. The bar79is fastened to the pipe77with the element for fastening81.

Everything, except for the pipe60, which ½″ and the pipe77, is ¾″. The joints44,45,48,54,57enable rotation of the elements fastened to them, but only around a horizontal line.

The computer tower is placed on the pedestal83which consists of the boxes1and2and L-profiles3and4and between the pipes23,24,25,26so that its rear part could be turned to the weight18. The boxes5and6to which are welded the carriers7and8bearing the castors9and10, need to be sufficiently pulled out from the boxes1and2so that the castors9and10should each be 15 cm away from the boxes1and2, thereby providing the full stability of the movable ergonomic carrier of the monitor weighing up to 5 kg and particularly when the monitor, keyboard and mouse are at the maximum distance from the computer tower. The monitor can be placed on the mount52arm and fastened with bolts. The keyboard is placed to the keyboard68and69carriers so that its lower edge fits the curved parts of the keyboard68and69carriers. That can be achieved regardless of the shape of the lower keyboard edge since the keyboard68and69carriers can be independently pulled out of the guides64and65of the keyboard carrier up to a certain length and fastened in the suitable position. To the upper ends of the keyboard68and69carrier, the elements72and73for the keyboard fastening lean to the upper edge of the keyboard and are fastened with the elements74and75for fastening. That secures the keyboard stability. The mouse is placed in its pedestal80the edges of which in the front part are mildly lifted in order to keep the mouse from falling from the pedestal80when it is out of use.

The user adjusts the distance of the monitor from himself by grabbing the flanks of the monitor and rotating the bar46and the pipes47and50which include the joints44and48, and moving the monitor sideways where the castors9and10are located and thus adjust the distance by pulling closer or pushing away. When the user positions the monitor at the suitable distance, he can position the monitor vertically as it suits him That can be done in two ways. The first, by rotating the mount52arm vertically. The second, by pulling out the bar42to the suitable height and fixing it with the element38for fastening.

The user can adjust the distance of the keyboard and mouse from him by rotating the pipe53and55and the pipe60which feature the joints45,54,57by grabbing with the left hand the ball82, which is bolted to the top of the pipe60, and the pedestal of the mouse80with the right, pull the side where the castors9and10are located and thus regulate the distance by pulling it towards or away from himself. The keyboard height adjustment is carried out by pulling out the bar43to the suitable height and fix it with the element39for fastening. The angle adjustment of the keyboard to the user can be carried out horizontally and vertically. Horizontal adjustment can be done in two ways. The first way is to adjust the angle of the keyboard by rotating the pipe60in the sleeve59, and when it assumes the suitable angle, the pipe60is then fastened to the sleeve59with the element61for fastening. The second way is to adjust the keyboard angle by rotating the sleeves62and63around the pipe60, and when it assumes the suitable angle, the sleeves62and63are then fastened to the pipe60with the elements66and67for fastening. The keyboard angle can be vertically adjusted by rotating the bar56in the pipe55, and when it assumes the suitable angle the bar56is then fastened to the pipe55with the element58for fastening.

Angle adjustment of the mouse80pedestal may be carried out by rotating the bar76in the pipe60so that when the mouse80pedestal assumes the suitable angle, the bar76is fastened to the pipe60with the element78for fastening. The pedestal80of the mouse can be moved to the right to the length of up to 17 cm by pulling out the bar76. The height adjustment of the mouse80pedestal can be done by pulling out the bar79to which the mouse80pedestal is welded, which goes into the pipe77. If the user wants to use the computer in the sitting position, he needs to set the ergonomic carrier as shown in theFIG. 1, but the chair needs to be placed in front of the front tower and not sideways to the castors9and10. If the user wishes to use the computer in the standing position he needs to adjust the ergonomic carrier as shown in theFIG. 2, and he can stand in different positions in relation to the computer tower. If the user wants to use the computer in the lying position, he needs to adjust the ergonomic carrier as shown in theFIG. 3. The carrier needs to be placed to the side of the bed so that the flank of the computer tower is parallel to the bed at the distance of 50 cm. The bar46can rotate together with the pipes47and50and the mount52arm through the joints44and48so as to enable the monitor placed on the mount52arm to be over the bed. TheFIG. 3shows the mobile ergonomic carrier adjusted to enable the user to use the computer while lying, with the tower being to his left. If the user wishes to use the computer with the tower being to his right, he needs to transfer the bar42from the pipe23into the pipe25together with the bar46and the pipes47and50and the mount52arm to which it is connected with the joint44. The mount52arm must be rotated horizontally for 180° around the part of the bar51which goes into it and fix it with the element53for fastening. Then the user must transfer the bar43from the pipe24into the pipe26together with the pipes53,55and60with which it is connected with the joint45. The Sleeve59is to be fastened to the pipe60closer to the end with the mouse80pedestal. The weight18is then to be transferred to the opposite side and fastened in the places16and17.

INDUSTRIAL APPLICABILITY

The invention can be used by anyone who owns a desktop computer, whether for business, studying, internet surfing or gaming. When adjusted for the standing position, the invention may find application in places where the computer is suitable to be used in that position, such as presentations, lectures studies and medical practices etc.

It can also be used in offices by placing it to the left or right side of the desk and rotating the monitor, keyboard and mouse so as to position them over the desk. Furthermore, it can also be used by persons forced to spend time in the lying position due to handicap or injury, as well as garners because of the length of time they spend by the computer.
