Shelf for display of goods

1. A goods display shelf comprising: a plurality of roller units, each roller unit having a plurality of rollers and a fixed frame; the fixed frames are interconnected to expand the width of the display shelf to enable more goods to be stored on the display shelf; end caps which are inserted into a tip portion and a terminal portion of each fixed frame; and

front and rear support frames into which the respective end caps are inserted, the front and rear frames each comprise an inserting groove that is adapted to receive a separation prevention plate which is used to prevent items from falling off the display shelf, wherein the fixed frames are classified into a planar-type fixed frame having a row of corresponding rollers without a guide plate, an “L”-type fixed frame having a row of corresponding rollers with a guide plate protruding integrally upward from a side thereof, and a “T”-type fixed frame having a guide plate protruding integrally upwardly from a center of thereof and a row of corresponding rollers on each side of the guide plate, wherein the guide plates used to divide the display shelf into compartments for storing items; hook holes being formed on an inner bottom of a tip portion and an inner bottom of a terminal portion of each of the “L”-, “T”-, and planar type fixed frames,

wherein the end caps are classified into first end caps, which are inserted into the respective tip portions and terminal portions of the “L”- and planar-type fixed frames, and second end caps, which are inserted into the respective tip portion and terminal portion of the “T”-type fixed frame,

a hook piece being formed on each of the first end caps and each of the second end caps such that the corresponding hook pieces are each inserted and hooked to the respective hook holes of the “L”-, “T”-, and planar-type fixed frames in a generally downward motion,

wherein hook bumps each having an inclined surface are formed on opposing sides of a bottom portion of each of the first end caps and hook bumps are formed on opposing sides of a bottom portion of each of the second end caps, wherein the hook bumps of each first end cap face each other, and the hook bumps of each second end cap face each other

wherein a “T”-shaped rail is formed on a horizontal part of each of the front and rear support frames such that the respective L″-, “T”-, and planar-type fixed frames are each mounted to the front and rear support frames by inserting the “T”-shaped rails of the front and rear support frames between the inclined surfaces of corresponding hook bumps of the respective first end caps and the respective second end caps in an interlocking manner.

2. The goods display shelf according to claim 1 , further comprising:

a rubber stopper inserted into corresponding inserting grooves of the first end caps and the second end caps.

3. The goods display shelf according to claim 1 , further comprising:

a separation device configured to separate the first end caps from the front and rear support frames, wherein the separation device comprises an inverted U-shaped support frame having grooves at a bottom portion thereof such that the inverted U-shaped support frame is seated on the “T”-shaped rail of each of the front and rear support frames,

tweezers comprising a fixed hook support and a mobile hook support on opposed inner sides of the inverted U-shaped support frame,

an operating part, which passes through a top center of the inverted U-shaped support frame and is connected to a top center of the tweezers at a bottom end in order to move the tweezers upwards or downwards, and

a spring having ends that are attached to the fixed hook support and the mobile hook support of the tweezers.
