Abstract

A shelf for a showcase in which a roller unit is formed with holding grooves on both sides of a bottom surface of a U-shaped roller plate. Fixing frames coupled with the roller plate include a bottom part, formed with a vertical rib to be fitted into the holding groove of the roller plate, and a vertical wall surrounding an outside of the roller plate and formed with a horizontal rib closing opened parts of fitting grooves of the roller plate, so that the fixing frames are mounted on both sides of the roller plate of the roller unit in pair correspondingly to each other. The vertical walls are formed with screw-coupling holes at front and rear ends in accordance with screw holes punched at both side walls of the end caps so as to be integrally coupled together by coupling screws.

Claims

1. A shelf for a showcase comprising a roller unit including a U-shaped roller plate having both side walls provided with a plurality of fitting grooves, to which mounting shafts protruded at both side ends of rollers are rotatably inserted;

fixing frames coupled with the roller plate by closing opening parts of the fitting grooves for preventing deviation of the rollers after the rollers are fitted into the roller unit; and

end caps fitted to front and rear ends of the fixing frames, characterized in that;

the roller unit is provided with holding grooves on both sides of a bottom surface of the roller plate, and each of the fixing frames includes a bottom part formed with a vertical rib to be fitted into the holding groove of the roller plate, and a vertical wall surrounding an outside of the roller plate and formed with a horizontal rib closing the opened parts of the fitting grooves of the roller plate, so that the fixing frames are mounted on both sides of the roller plate of the roller unit in pair, wherein the vertical walls are provided with screw-coupling holes at front and rear ends to be coupled with screw holes formed on both side walls of the end caps by screws.

2. The shelf as claimed in claim 1, wherein the vertical wall of any one of the fixing frames is provided with holding protrusions at upper and lower parts thereof, and the vertical wall of an adjacent fixing frame is provided with fitting protrusions to be fitted with the holding protrusions, so that the holding protrusions and the fitting protrusions are coupled with each other horizontally.

3. The shelf as claimed in claim 1, wherein a connection frame includes a bottom part having vertical ribs formed on both sides to be fitted into the holding grooves of first and second roller plates of roller units, and a vertical wall formed in the center of the bottom part for surrounding adjacent outsides of the first and second roller plates and having a horizontal rib for closing opened parts of fitting grooves of the first and second roller plates, so as to align two to six roller units in connection, the fixing frames are mounted to exposed outsides of the first roller plate and a final roller plate, and the end caps to be mounted at the front and rear ends are formed with holding grooves and inserting grooves so that the connection frame is fitted into the end caps and fixed to the end caps.

4. The shelf as claimed in claim 3, wherein one roller unit may be used alone as a single unit or two, three, or six roller units can be used as a single unit depending on use of the fixing frames alone or in combination with the connection frames, wherein the end caps are separately formed so as to be mounted on the front and rear ends.

5. The shelf as claimed in claim 2, wherein a connection frame includes a bottom part having vertical ribs formed on both sides to be fitted into the holding grooves of first and second roller plates of roller units, and a vertical wall formed in the center of the bottom part for surrounding adjacent outsides of the first and second roller plates and having a horizontal rib for closing opened parts of fitting grooves of the first and second roller plates, so as to align two to six roller units in connection, the fixing frames are mounted to exposed outsides of the first roller plate and a final roller plate, and the end caps to be mounted at the front and rear ends are formed with holding grooves and inserting grooves so that the connection frame is fitted into the end caps and fixed to the end caps.

6. The shelf as claimed in claim 5, wherein one roller unit may be used alone as a single unit or two, three, or six roller units can be used as a single unit depending on use of the fixing frames alone or in combination with the connection frames, wherein the end caps are separately formed so as to be mounted on the front and rear ends.
