Detailed Description of the Invention

Figures 1 and 2 show a movable shelf system (100) comprising a base frame (200) having a plurality of shelves (300) on which products and goods are placed, and can be integrated to refrigerators especially. The invention comprises rail frame (201 ) comprising rail slots (202) having rotation line (600) that allows movements of shelves (300) and returning said shelves (300) from the starting point to the same starting point, a plurality of shelves (300) moving on said rail slots (202) by means of wheels (301 ), and a drive group (400) allowing movement of said shelves (300) on said rail slots (202) via automatic or manual impact.

The drive group (400) used in the system comprises a servo motor (401 ). Figure 4 shows a transmission component (402), by which the drive generated by means of said motor (401 ) is transferred. This transmission component (402) is preferably a chain, belt, timing belt, or reducer. The invention comprises a main drive gear (403), to which the motion is transferred by means of said transmission component (402). On the other hand, it comprises a main motion transmitter (404) connected to the drive gear (403) and extending from the central point of the drive gear (403) to the region close to the top peak point (T) of the frame structure, along hi distance. Yet, this main motion transmitter (404) preferably comprises a chain, belt, or timing belt. A product inlet direction (304) of the shelves (300) is formed on the side of the base frame (200) facing the outer edge (500).

As can be seen in Figure 3, a free moving gear (405) is connected to the main motion transmitter (404) and positioned from the central point of the drive gear (403) to the region close to the top peak point (T) of the frame structure, along hi distance. Yet, in Figure 5, a plurality of connection arms (406) are shown, one end of which is connected to the main motion transmitter (404), while the other end is connected to the shelves (300). Said connection arms (406) have a triangular shape, in which the single connection point (4061 ) is connected to the shelves (300) and the double connection point (4062) is connected to the main motion transmitter (404). Said single connection point (4061 ) has a free rotating bearing (4063). A plurality of wheels (301 ) is formed at the outer edge surfaces

(302) of said shelves (300). The invention also comprises a motion extension

(303) providing an operating distance between the outer edge surface (302) of said shelves (300) and the rail frame (201 ). The rail frame (201 ) comprises radiused surfaces (203) with rounded four corners extending in a rectangular form from the base (Z) on which they are positioned.

The way of operation of the movable shelf system (1 00) is as follows. The first drive impact is formed by means of the motor (401 ) fixed on the base frame structure. This drive impact can preferably be guided via a manual lever, electric switch, remote control, or touch screen. The initial drive impact coming from the motor (401 ) is transmitted to the main drive gear (403) via a belt and pulley type transmission component (402). The rotational motion is transmitted to the main motion transmitter (404) by means of the drive gear (403). The main motion transmitter (404) is preferably a chain, and a plurality of connection arms (406) are mounted on this chain. The other end of the connection arms (406) is connected to the shelves (300). With the rotation of the main motion transmitter (404), the connection arms (406) found thereon also rotate, and thus rotate the shelves (300) to which they are connected, in a-direction or b-direction. This rotational motion operates with the logic of a Ferris wheel. Advancement of the shelves (300) on a line and within desired limits is ensured by means of wheels (301 ) and rail frame (201 ) and rail slots (202) in which the wheels (301 ) are guided. By means of placement of each wheel (301 ) in the rail slot (202), their movement is restricted within these limits along the rail frame (201 ) line.

Figure 7 shows a two-dimensional view of the bearing shaft (4064) positioned among the drive groups (400). The drive gear (403) is configured at both side areas of the movable shelf system (100). They are fixed by means of a bearing shaft (4064) in order to ensure rigid bearing and centering between both drive gears (403).
