The present invention relates to a supplementary shelf assembly for a refrigerator. The supplementary shelf assembly of the present invention comprises a pair of support skirts mounted on a ceiling of a storage space and formed with at least two guide slots in front and rear ends thereof; at least two support links each of which includes a connection portion having a length relatively shorter than a distance between the support skirts, support guide portions extending perpendicular from both ends of the connection portion, respectively, and penetration portions extending outwardly and in parallel to the connection portions from ends of the support guide portions and penetrating the corresponding guide slots to be moved along the guide slots, respectively; and a supplementary shelf rotatably supported by the connection portions, and moved forward or rearward of the storage space and then elevated or lowered to be selectively located on a position near the ceiling of the storage space or on a position spaced apart by a predetermined interval from the ceiling of the storage space. According to the present invention, since a front and rear length of the supplementary shelf is equal to that of the main shelf, the storage space can be effectively utilized. Further, since the supplementary shelf is inadvertently swung due to a simple structure during its use, the supplementary shelf assembly can be simply manufactured and assembled. Furthermore, since the accommodation and withdrawal of the supplementary shelf is performed in regular manner, the operational reliability thereof can be improved and storage articles can be stably placed on the supplementary shelf.

What is claimed is: 1. A supplementary shelf assembly for a refrigerator, comprising: a pair of support skirts mounted on a ceiling of a storage space and formed with at least two guide slots in front and rear ends thereof; at least two support links each of which includes a connection portion having a length relatively shorter than a distance between the support skirts, support guide portions extending perpendicular from both ends of the connection portion, respectively, and penetration portions extending outwardly and in parallel to the connection portions from ends of the support guide portions and penetrating the corresponding guide slots to be moved along the guide slots, respectively; and a supplementary shelf rotatably supported by the connection portions, and moved forward or rearward of the storage space and then elevated or lowered to be selectively located on a position near the ceiling of the storage space or on a position spaced apart by a predetermined interval from the ceiling of the storage space, wherein the guide slots have elongated shapes to allow the penetration portions to move between forward and rearward positions along the support skits when the supplementary shelf is elevated relative to the ceiling of the storage space, and wherein movement of the penetration portions in the guide slots causes the supplementary shelf to move by a proportional distance relative to the support skirts, and wherein link holders to which the connection portions are rotationally received are formed on the bottom surface of the supplementary shelf, and swing-resistant ribs brought into close contact with both sides of each of the link holders to prevent the supplementary shelf from being swung in a right and left direction are provided on the connection portion. 2. The supplementary shelf assembly as claimed in claim 1, wherein the ceiling of the storage space on which the support skirts are mounted is a bottom surface of a main shelf by which a storage space is divided into upper and lower spaces. 3. The supplementary shelf assembly as claimed in claim 2, wherein the supplementary shelf is moved forward or rearward with respect to the main shelf by a length of the support guide portion to be accommodated at or withdrawn from a position just below the main shelf between the support skirts in a state where the supplementary shelf is elevated. 4. The supplementary shelf assembly as claimed in claim 1, comprising: wherein each of the support skirts includes: guide ribs formed lengthwise along upper ends of the guide slots to restrict a rotation range of the support guide portions and also to guide motions of the support guide portions; and support ribs formed lengthwise along lower ends of the guide slots to support the support guide portions and to guide the motions of support guide portions in a state where the supplementary shelf is accommodated at the position just below a main shelf. 5. The supplementary shelf assembly as claimed in claim 4, wherein a distance between the guide slots is equal to the length of the support guide portion. 6. The supplementary shelf assembly as claimed in claim 5, wherein each of the support ribs is formed with a catching projection on a front end thereof to prevent the penetration portion from being moved along the guide slot until the supplementary shelf is elevated and the rotation of the support guide portion is then limited by the guide rib. 7. The supplementary shelf assembly as claimed in claim 6, wherein stoppers for restricting the rotation range of the support guide portions are formed on the support skirts at positions in front of the front ends of the guide slots. 8. The supplementary shelf assembly as claimed in claim 1, wherein at least two link holders are provided on each of the connection portions. 9. The supplementary shelf assembly as claimed in claim 8, wherein the link holders are formed at positions near front and rear ends on the bottom surface of the supplementary shelf, and the rear link holders are spaced apart by at least the length of the support guide portion from the front link holders and from the rear end on the bottom surface of the supplementary shelf. 10. The supplementary shelf assembly as claimed in claim 1, wherein the guide slots have substantially a same elongated shape. 11. A supplementary shelf assembly for a refrigerator, comprising a pair of support skirts mounted on a ceiling of a storage space and formed with at least two guide slots in front and rear ends thereof; at least two support links each of which includes a connection portion having a length relatively shorter than a distance between the support skirts, support guide portions extending perpendicular from both ends of the connection portion, respectively, and penetration portions extending outwardly and in parallel to the connection portions from ends of the support guide portions and penetrating the corresponding guide slots to be moved along the guide slots, respectively; a supplementary shelf rotatably supported by the connection portions, and moved forward or rearward of the storage space and then elevated or lowered to be selectively located on a position near the ceiling of the storage space or on a position spaced apart by a predetermined interval from the ceiling of the storage space; and coupling links having both ends rotatably coupled to the support links to allow the support links to be moved together. 12. The supplementary shelf assembly as claimed in claim 11, wherein partially opened rings with insertion holes are formed at both ends of the coupling link, respectively, and the penetration portions penetrate the corresponding guide slots and fitted into the insertion holes rings, respectively, so that the support links and the coupling link can be rotationally connected with each other. 13. The supplementary shelf assembly as claimed in claim 12, wherein the insertion hole of the ring formed on one end of the coupling link is opened toward the end of the coupling link to be inclined at a predetermined angle with respect to a longitudinal axis of the coupling link, and the insertion hole of the ring formed on the other end of the coupling link is opened downward to be perpendicular to the longitudinal axis of the coupling link. 14. The supplementary shelf assembly as claimed in claim 13, wherein the predetermined angle is 45 degrees. 15. The supplementary shelf assembly as claimed in claim 14, wherein a distance between the connection portions connected to the supplementary shelf is relatively shorter than a distance between the insertion hole of the rings of the coupling link.
