DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to an improved display unit and an arrangement of this display unit in premises furnished with an opening.
It applies in particular to shelves in shops selling for example flowers, sweets, clothes, etc.
BACKGROUND OF THE INVENTION
Conventionally, the shelves are placed outside, in front of the shop. When the shop closes, the shelves have to be stored at the back of the shop, this requiring daily laborious manhandling of the display units and merchandise placed thereon.
SUMMARY OF THE INVENTION
The aim of the invention is in particular to do away with the laborious manhandling related to the erecting and laying out of the shelves, and to do so by proposing a display unit which provides for the very flexible display of the merchandise during shop opening periods and storage of this merchandise during periods when the shop is closed while still displaying them commercially through a window.
For this purpose the subject of the invention is a display unit characterized in that it comprises a main chassis fitted articulated about a shaft with horizontal axis, furnished with at least one shelf carried by a horizontal spindle fitted pivoting about its axis to two uprights of the main chassis, means for the movement of the main chassis between a position of confined floor space and a display position, and means for stabilizing the angular position of each shelf independently of the position of the main chassis.
According to characteristics of various embodiments of the invention: axis, and the means for the angular stabilization of each shelf comprise means for coupling the corresponding shelf-carrying spindle with the articulation shaft; of coupling with the articulation shaft comprise at least one chain or belt for coupling two wheels, one secured to the shelf-carrying spindle and the other to the articulation shaft; shelf-carrying spindle, comprising two vertically and horizontally mutually offset shelves; this chassis about its articulation shaft; furnished with a first end fitted pivoting about an axis parallel to the articulation shaft and with a second end fitted sliding in a glideway secured to the main chassis; the vertical movement of the articulation shaft, these means being coupled with the swinging means; least one component with nut secured to the articulation shaft cooperating by screwing with a vertical threaded drive rod; of the uprights of the main chassis, each frame carrying a swing arm whose sliding end is furnished with an articulated pad cooperating with a glideway-forming member secured to a corresponding upright of the main chassis, a threaded drive rod cooperating by screwing with a component with nut secured to a corresponding end of the articulation shaft, means for coupling the swing arm and the threaded drive rod, the threaded drive rods of the frames being coupled to at least one drive motor or to manual drive means; least one set of linkages delimiting an articulated parallelogram including two first parallel sides, one of which is fixed and the other of which is secured to the articulation shaft while being movable by the pivoting of the other two parallel sides of the parallelogram; of the uprights of the main chassis, each frame carrying a swing arm whose sliding end is furnished with an articulated pad cooperating with a glideway-forming member secured to a corresponding upright of the main chassis, a set of linkages forming an articulated parallelogram whose mobile aide parallel to the fixed side is secured to a corresponding end of the articulation shaft, means for coupling the swing arm and a pivoting side of the parallelogram, the swing arms of the frames being coupled to at least one drive motor or to manual drive means; of the main chassis and of its loading during its movements; comprise a spring leaf, located in each of the frames, furnished with a first fixed end and with a second end sliding along the corresponding swing arm while being pressed elastically against the latter; articulation shaft towards its topm
