System for vertically adjusting a shelf

Abstract

The present invention refers to a system for vertically adjusting a shelf, such as in refrigerating appliances, cabinets, lockers and similar, said shelf comprises horizontal support members ( 10, 11 ) arranged perpendicularly to vertical guides ( 1, 2 ) where they can be vertically adjusted, and a deposit plate ( 12 ), a drawer or similar, being attached to said horizontal support members ( 10, 11 ).
