BACKGROUND OF THE INVENTION1. Field of the Invention
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 arranged perpendicularly to vertical guides where they can be vertically adjusted, and a deposit plate, a drawer or similar, being attached to said horizontal support members.
2. Description of the Related Art
The aforementioned system for vertically adjusting a shelf is known from international patent applications No. WO 2008/095775, WO 2008/095545 and WO 2006/120102. All the said known solutions have several drawbacks. The fact that a shelf, when raised and afterwards lowered, can freely fall is particularly outstanding. Furthermore, in order to adjust the shelf vertically it must be moved and rotated in several directions, representing a sever obstacle for a user. In addition to inaccurate vertical adjusting of the shelf, the embodiment of the system itself is rather technologically demanding and time consuming.
SUMMARY OF THE INVENTIONIt is the object of the present invention to create a system for vertically adjusting a shelf of the aforesaid kind with which said drawbacks of the known solutions will be remedied.
According to the invention, said object is solved by a shelf being fixed in a form-locking and friction-type manner in vertical guides by means of horizontal support members. Each said vertical guide, having a C-shaped cross-section, comprises a web formed with a plurality of through holes for passing the air, and a side arranged opposite to said web, said side being formed with folds facing each other. Preferably, the free end of at least one fold is formed with a gearing extending over the entire length of each said guide.
Furthermore, it is provided for according to the invention that each said horizontal support member is formed on the side cooperating with each of said guides with a flange-like extension, an oblong and relatively narrow tongue-like projection being associated thereto in longitudinal direction. The upper section of said projection is formed with a pair of vertically and horizontally spaced circular projections intended to mesh with said gearing of each guide. Thus, a form-locking connection between the guide and the horizontal support member being provided in this manner. Said friction-type connection between the guide and the horizontal support member is created in a manner that the surface of the flange-like extension facing the guide is pressed against each guide due to dead load of the shelf.
An embodiment of the invention will now be described with reference to the accompanying drawings without being limited thereto.
A system for vertically adjusting a shelf being described in details with reference to a cooling appliance comprises at least one, preferably two vertical guides 1, 2 being mutually spaced and formed in the cross-section as the letter C. Since said guides are preferably identical, only the first guide 1 is fully described in the foregoing and with reference to
To each of said guides 1, 2 there is attached by means of a form-locking connection and on the principle of a cantilever a slender support member 10, 11, said form-locking connection being fully described below, wherein said support member 10, 11 being relocatable in the longitudinal direction of said guides 1, 2 and a deposit plate 12 being superimposed on said support members 10, 11. Since both said support members are identical only the first support member 10 is fully described in the foregoing and with reference to
The shelf consisting of said support members 10, 11 and said deposit plate 12 is vertically adjusted in said vertical guides 1, 2 in a manner that it is lifted up at the end averted from said vertical guides 1, 2 so that it rotates about its centre of rotation which lies approximately in the horizontal axis of said slider 24. It is provided for in this manner that said circular projections 21, 22 unmesh the gearing 8, 9 due to which the shelf can be moved in height for the arbitrary number of teeth of the gearing 8, 9. The precision of the adjusting the shelf according to the invention depends on the size of the teeth of the gearing 8, 9, the pitch of said teeth and the diameter of said circular projections 21, 22. The system as described above provides for a form-locking fixing of the shelf. The shelf according to the invention is additionally fixed in a horizontal position in a manner that a surface 27 of the flange-like extension 18 facing the vertical guide 1, 2 is pressed, due to dead load of the shelf, against the vertical guide 1, 2 and, respectively, against a decorative profile 28 which optionally covers each vertical guide 1, 2. In this manner a friction-type blocking of the shelf is obtained.
