[0001] The present invention relates to a refrigerator, in particular a domestic refrigerator,
having an internal compartment with side walls, each side wall being provided with
molded parts for supporting at least one glass shelf.
[0002] A refrigerator of the above kind is disclosed by
EP 2606295 where the molded parts are grooves of the inner liner adapted to cooperate with support
rails on which the shelf can slide.
[0003] Such construction is quite complex since need at least three element on each side
of the shelf, i.e. the groove, the support rail and a shaped rail fixed to the shelf.
Moreover this solution is mainly focused on sliding shelves and not sliding drawers.
[0004] In the modern refrigerators there is the trend of allowing the user to arrange the
inner part of the refrigerator depending on his will. So he can decide to have simple
glass shelves or sliding drawers in the refrigerator cavity.
[0005] Object of the present invention is to provide a refrigerator in which the user can
easily pass from a cavity with shelves only to a cavity with shelves and drawers.
[0006] Another object is to provide the user with a good feedback during the use of the
drawers. The above objects are reached thanks to the feature listed in the appended
claims.
[0007] In particular, the present invention avoids the lateral wobbling of the drawer and
its vertical movement. In this way, during the use of the drawer, the customers feel
a precise extraction of the drawer, similar to the use of metal telescopic rails.
[0008] The basic concept of the present invention consists of two plastic elements inserted
at the glass shelf sides.
[0009] In the upper part of the plastic elements, some protrusions allow to block the sliding
movement of the drawer.
[0010] According to another feature, lateral parts of the plastic elements allow keeping
the glass shelf in the center of the compartment or cell.
[0011] According to another feature, in the front part of each shelf, two elastic ribs with
pins block the glass shelf on the cell, avoiding its movement during food items handling
or during pull out of the drawer. In addition, they compensate the unavoidable deformation
of the cabinet.
[0012] Plastic elements are made of POM to allow a better sliding of the drawer. In an alternative
solution, plastic elements may be made of cheaper plastic material (for instance PP)
with co-molded shaped protrusion of POM on which the drawer can slide.
[0013] Further advantages and features of the present invention will be clear from the detailed
description of one embodiment thereof, with reference to the attached drawings in
which:
- Figure 1 is a perspective view of a portion of a shelf according to the invention
immediately before its mounting on the side walls of the refrigerator compartment;
- Figure 2 is a perspective view of a portion of the shelf mounted on the side walls
of the compartment;
- Figure 3 is a partially sectioned view of what is shown in figure 2;
- Figure 4 is a perspective view of a sliding drawer mounted on the shelf, where the
side walls of the compartment have been removed for sake of clarity;
- Figure 5 is an enlarged view of a detail of figure 4,
- Figure 6 is a detail of a shelf viewed from the bottom thereof, and
- Figure 7 is a perspective view of a component according to the invention.
[0014] With reference to the drawings, a refrigerator R comprises an inner cavity C where
a plurality of glass shelves G is mounted. Each shelf G is provided, on parallel sides,
with plastic elements 10 having a C-shaped cross section mounted on edge 12 of the
shelf G. Each plastic element 10 may have a continuous C-shaped portion 11 a (as shown
in figure 7) or it can have a C-shaped slotted portion 11 b (as shown in figure 6),
both C-shaped portions 11 a, 11 b (continuous or slotted) having the same purpose
for mounting the plastic element 10 on the shelf.
[0015] The inner walls W of the compartment C present two molded parts 14 and 17 which may
be obtained by thermoforming the plastic inner liner, or by using components obtained
by injection molding and inserted in aperture of the liner in a foam tightly manner.
With the term molded parts we mean the above solutions, and any alternative solution
as well.
[0016] The front molded part 14 comprises a blind hole 14a for receiving a pin 16a of an
elastic portion 16 of the plastic element 10 which protrudes laterally and in the
front portion thereof. The detail of the mounted configuration is shown in figures
2 and 3, where the pin 16a is elastically inserted in the blind hole 14a.
[0017] The front portion of the plastic element 10 present a cross part 10a which avoids
any sliding of the glass shelf G toward the outside, while any backward movement of
the shelf G is prevented by a similar cross part 10b present in the rear portion of
the plastic element 10 (figure 5) or by the rear wall of the compartment.
[0018] On the upper side of each plastic element 10, with reference to the installed configuration
of the element, there are two series of protrusion 18 and 20. A first series of protrusions
are simple linear protrusions on which a bottom wall of a plastic drawer 22 can slide.
The protrusions of the second series are hook-shaped and are configured to cooperate
with side rails 24 of the bottom of the drawer 22 for avoiding any tilting movement
thereof. Moreover, each plastic element 10 is provided with a protrusion 26 on the
front part of the element which is shaped so as to guide the drawer 22 and its side
rails 24 in the initial mounting sliding movement of the drawer itself.
[0019] Each plastic element 10 is also provided with a side elastic tongue 28 which keeps
the glass shelf G in the center of the compartment.
[0020] From the above description it is clear how the mounting of the glass shelf G in the
inner compartment C is simple and safe, since the plastic element 10 are coupled with
two opposite side of the glass plate, and then the glass shelf G (including the glass
plate and the plastic element 10) is inserted elastically in the molded parts. If
the user wants to install a sliding drawer 22 in the space defined by two glass shelf
G, he has to simply insert the drawer on the glass shelf and in this coupling movement
he is helped by the shaped protrusion 26.
[0021] For avoiding the tilting movement when the drawer reaches its fully opened configuration,
the drawer 22 presents lateral protrusion 30 configured to cooperate with corresponding
protrusion (not shown) of the inner liner.
[0022] The series of protrusion 18 and 20, where the drawer 22 slides may be of a plastic
co-molded material different from the material of the plastic element and having a
lower friction coefficient; this may reduce the overall cost of the plastic elements
10.
