The present invention relates to a carrying system for facilitating change of furniture position lowered down during movement and lifted up after the movement is completed.

Background of the Invention

Users have great difficulty when they want to relocate large and heavy furniture that are often used in living spaces such as homes or offices or clean under thereof. Although there are quite a lot of wheeled products today, they are rarely preferred yet in furniture sector. In furniture wherein use of wheel (caster) is preferred, wheels are generally installed to furniture legs fixedly and furniture stand on wheels rather than on their own feet. And this this leads to a disruption in aesthetic appearance of furniture. Therefore, there is need for a carrying system with a wheel which both does not spoil aesthetic appearance of furniture and provides ease of carriage during their movement from one place to another.

The Chinese Utility Model document no. CN205082904, an application in the state of the art, discloses a desk with hidden movable wheel. The desk comprises a desktop and at least one table leg installed below the desktop. The lower extreme of the table leg is a hollow tubular (with circular or rectangular cross-section) structure. The inner chamber of the table leg is coaxially placed to a slider that is slidable upwards and downwards along the axis of the table leg. The lower extreme of the slider is installed to a wheel. When the table is to be moved over the floor, movement is easily achieved without scratching the floor and breaking the table legs by means of the wheel. The wheel is pulled upwards by means of the slider and it is completely hidden inside the table leg when the table is not moved. A rotating shaft is placed perpendicular to the axis of the table leg. A cam is located at the end of the rotating shaft remaining within the table and a handle is located at the outer end thereof. Upon the handle is rotated, the rotating shaft makes a rotational motion and moves the cam slider downwards. In the groove located at the inner side of table leg, the tab on the side wall of the slider moves slidably and this structure also prevents the motion from going beyond a certain distance as well. The said table leg enables easy movement on the wheel during the table movement and after the movement is completed, it ensures that the table stands on the floor on the table leg by hiding the wheel.

The Korean Patent document no. KR100925837, an application in the state of the art, discloses a furniture which offers easy movement by changing the position of the wheel it has. Therefore, the furniture comprises a body, a wheel unit, a spring and a drive unit. The drive unit comprises a drive motor, a drive gear and a movable shelf bar. The drive motor rotates the drive gear to move the movable shelf bar in the horizontal direction and this movement enables the wheel to contact the floor by pushing the wheel assembly section down. When it is desired to relocate the furniture, the wheel contacts the floor and movement is provided on the wheels upon the furniture legs rise from the floor. However it is not disclosed in this document that the circular motion is transferred in the same way and thereby the motor can provide mobility by connecting directly to the wheels without the need for other elements such as screws and bolts when required.

- at least one wheel retaining element (3) which retains the wheel (2) from its center;

- at least one inner part (4) which is in association with the wheel retaining element (3) from its upper part, and which is one of the elements enabling upward and downward movement of the wheel (2);

- at least one outer part (5) which enables position change of the wheel (2) in vertical direction by sliding upwards and downwards outside the inner part (4), and which is installed to the furniture;

- at least one sliding element (6) which is installed to the inner surface of the outer part (5), and which ensures that upward and downward movement is performed by minimum friction;

- at least one first motion transmission element (7) which enables upward and downward of the inner part (4) inside the outer part (5) by rotational motion;

- at least one deflector box (8) which is installed onto the outer part (5), and which contains the deflection elements; and

- at least one power supply (9) which supplies the power providing motion to the deflector boxes (8).

The wheel (2) included in the inventive carrying system (1) is a material in the form of cylinder cross-section moved downstream in order to contact the floor in the event that the furniture is relocated. The wheel (2) is hidden inside the furniture legs in order not to spoil the appearance of the furniture by means of the upward movement of the inner part (4) and thus it is ensured that the furniture stands on its own feet, when the relocation process of the furniture is over. The wheel (2) can be selected in appropriate dimensions according to the weight of the furniture to be relocated. The wheel (2) is made of a material whose surface can rotate comfortably on the floor since it offers the convenience of moving furniture from one place to another by rotating.

The wheel retaining element (3) included in the inventive carrying system (1) is a installed to the outer surface of the inner part (4) facing the floor. The wheel retaining element (3) establishes connection with the wheel (2) by passing through the hole in its center and grips the wheel. The wheel retaining element (3) is moved upwards by means of the inner part (4) so as to be hidden inside the furniture after the movement.

The inner part (4) included in the inventive carrying system (1) ensures that the wheel (2) is moved downwards when to be used by sliding inside the outer part (5). At the same time, the inner part (4) is moved upwards by sliding inside the outer part (5) after use of the wheel (2) is completed and it is hidden inside the furniture.

The outer part (5) included in the inventive carrying system (1) allows installation to comer points where furniture legs are located. The outer part (5) remains fixed during use of the wheel (2) and it does not extend out of the furniture by moving downwards. The outer part (5) creates sliding surface to the inner part (4) during upward and downward movement of the wheel (2).

The sliding element (6) included in the inventive carrying system (1) has a structure containing balls that roll between inner and outer rings. In a preferred embodiment of the invention, the sliding element (6) is a bearing. The sliding element (6) minimizes the motion that is obtained by the power supply (9) in the inner surface of the outer part (5) and received by transfer, to be subjected to friction loss.

In a preferred embodiment of the invention, the first motion transmission element (7) included in the inventive carrying system (1) has a structure in the form of cylinder and with gears on its outer surface. The first motion transmission element (7) contacts the sliding element (6) over its cylinder structure and the inner part (4) from under thereof. The first motion transmission element (7) enables the inner part (4) to be moved upwards and downwards as a result of the rotational motion transmitted to if by means of the gear structure.

The deflector box (8) included in the inventive carrying system (1) is used for moving a plurality of wheels (2) of a furniture upwards and downwards by the power supplied from a single power supply (9). The deflector box (8) has elements that convert the power supplied by the power source (9) into motion and change the direction of the movement. The deflector box (8) is installed preferably such that it is close to feet of the furniture. The motion transfer element (81) and the second motion transmission element (82) operate synchronously with each other inside the deflector box (8). The deflector box (8) can transmit the power received from the power supply to each wheel (2) separately by means of the element (81 and 82) included in it. The second motion transmission element (82) included in the deflector box (8) is in connection with the power source (9) and the motion transfer element (81). The second motion transmission element (82) converts the power it receives from the power source (9) into circular motion and transmits it to the motion transfer element (81). In a preferred embodiment, the second motion transmission element (82) is a shaft. The motion transfer element (81) is in connection with the second motion transmission element (82) and the sliding element (6). In a preferred embodiment, the motion transfer element (81) is a bevel gear. The motion transfer element (81) changes direction of the circular motion received from the second motion transmission element (82) and transmits it to the sliding element (6) preferably by changing it 90°.

The power supply (9) included in the inventive carrying system (1) provides the necessary power for obtaining circular motion by connecting to the deflector boxes (8) and for the wheel (2) -that are connected to the deflector boxes (8)- to contact the floor and return by going down during the furniture movement, and for the furniture to stand on its own feet by lifting up after the furniture movement is completed. The power supply (9) is preferably a DC motor. In a preferred embodiment, the power supply (9) can also enable the movement of the wheel (2) by connecting to the first motion transmission element (7) directly. The power supply (9) can be controlled by means of a software and it allows to perform relocation without touching the furniture.

The fact that it can mobilize all wheels (2) of furniture with a plurality of wheels (2) by means of the power source (9) provided from a single point, furniture can be relocated without touching it by adding a software to the system and the continuity of use of the wheel (2) is ensured upon the power supply (9) connects to the first motion transmission element (7) directly in the event that the deflector box (8) and the elements (81 and 82) in thereof are removed from the system as well because each element it has provides circular motion are the advantages of the inventive carrying system (1).

Within these basic concepts; it is possible to develop various embodiments of the inventive carrying system (1); the invention cannot be limited to examples disclosed herein and it is essentially according to claims.
