DETAILED DESCRIPTION OF THE INVENTION
[0040] In this context, a width direction of the shelf assembly, the shelf panel and the drawer correspond to a direction of a first horizontal axis x in FIG. 2.
[0041] In this context, a depth direction of the shelf assembly, the shelf panel and the drawer correspond to a direction of a second horizontal axis z in FIG. 2.
[0042] In this context, a vertical direction of the shelf assembly, the shelf panel and the drawer correspond to a direction of a vertical axis y in FIG. 2.
[0043] Referring now to the figures of the drawings in detail and first, particularly, to FIG. 1 thereof, it is seen that the present invention proposes a shelf assembly 100 for a cooling device 1 having a storage compartment 70 with an inner liner 71. The storage compartment 70 has a compartment storage space in which the foodstuffs and the shelf assemblies are provided. The inner liner 71 forms the inner walls of the cooling device 1 facing the compartment storage space. Those inner walls are sidewalls, a top wall, a bottom wall and a rear wall. The present invention as depicted in FIG. 2 and FIG. 3 presents the shelf assembly 100 of a cooling device 1 including a shelf panel 61, a pair of attachment devices 62 disposed in a parallel spaced relation, and a movable drawer 60 defining a storage cavity. There is a main frame 63 connected to a front side of the shelf panel 61. As can be seen in FIG. 2, the main frame 63 has two U-shaped channels. One of the U-shaped channels receives a front edge of the shelf panel 61. The other U-shaped channel receives a front end of a carrier bracket 30. On the other hand, the shelf panel 61 is provided with mutual bracket structures 50 for attaching the movable drawer 60 to the shelf panel 61. In a possible embodiment of the invention, each of the bracket structures 50 includes a connection bracket 14 for fixing the shelf assembly 100 to the inner liner 71, the carrier bracket 30 being formed with more than one engagement portion 31 laterally spaced one to another and a fixing bracket 10 connected to a lower surface of the shelf panel 61 facing the storage cavity, having more than one receiving recess 12 so as to receive the corresponding engagement portions 31. The fixing bracket 10 has a flat surface for bonding the fixing bracket 10 to a lower surface of the shelf panel 61 facing the fixing bracket 10, by an adhesive member which is not shown.
[0044] In a possible embodiment as shown in FIGS. 2 and 3, the drawer 60 is movable between a closed position in which the drawer 60 is completely inserted into a storage compartment 70 and an open position in which the drawer 60 is at least partially pulled out of the storage compartment 70 when in use. In other words, the drawer 60 can be slidably moved between the closed position in which the shelf panel 61 entirely covers an access opening of the drawer 60 and the open position in which the storage cavity can be accessible from outside of the drawer 60. The two attachment devices 62 are provided on the mutual walls of the drawer 60. Each of the attachment devices 62 attach to the corresponding carrier bracket 30.
[0045] As can be seen in FIGS. 4 and 10, the fixing bracket 10 further includes a longitudinal protrusion 39 which provides a retaining groove 11 provided along the fixing bracket 10 for at least partly receiving the carrier bracket 30. The retaining groove 11 has a substantially C-shaped cross-section. The fixing bracket 10 includes a suspension slot 13. As seen in FIG. 8, an inclined front wall 312 of the carrier bracket 30 is positioned into the suspension slot 13 in such a way that an inclined rear wall 313 rests against the circumferential walls of the suspension slot 13. Thus, the stability of the carrier bracket 30 is ensured.
[0046] As depicted in FIG. 6 and FIG. 9, the guiding channel 38 is equipped with more than one contact region 35 in the vicinity of a lateral surface of the drawer 60. Yet another feature of the contact region 35 is that it is constructed as a series of edge protrusions that extend along a first horizontal axis x of the shelf assembly 100.
[0047] FIG. 7 illustrates an exemplary embodiment of the invention disclosing more than one reinforcement rib 33 adjacent to a locking ramp 32. Each of the reinforcement ribs 33 have a substantially triangle cross-section, which provides structural strength and durability between an upper wall 40 and a bottom wall 41 of the carrier bracket 30. When the drawer 60 is pulled and brought to the open position, the center of gravity of the carrier bracket 30 shifts towards the front thereof. The reinforcement ribs 33 exemplified in FIG. 12 are disposed on the upper wall 40 so as to provide a shelf assembly 100 that is capable of withstanding conditions in which the drawer 60 remains extended and the load is unequally distributed.
[0048] As depicted in FIG. 11, the carrier bracket 30 is attached to the fixing bracket 10 as follows: Initially, the longitudinal protrusion 39 of the carrier bracket 30 is inserted into the retaining groove 11. Thereafter, the engagement portion 31 of the carrier bracket 30, which is a flexible member, is pushed towards the fixing bracket 10 and attaches into the receiving recess 12 provided on an upper part of the fixing bracket 10.
[0049] FIG. 13 represents an assembled state of the carrier bracket 30 and the fixing bracket 10. The carrier bracket 30 is provided with an abutment member 34 formed at a first end 43 of the upper wall 40. The distal end of the fixing bracket 10 towards the connection bracket 14 abuts against the abutment member 34 wherein the abutment member 34 and the connection bracket 14 are located at the opposite ends of the shelf assembly 100, when the carrier bracket 30 is attached to the fixing bracket 10. The abutment member 34 acts a damper on any probable vibrations of the fixing bracket 10 while the drawer 60 is pulled out of the of the cooling device 1. The abutment member 34 has a thickness that is substantially equal to that of the fixing bracket 10. Upon securing the carrier bracket 30 to the fixing bracket 10 an integrated structure is provided, which is endowed by the abutment member 34. Moreover, this integration ensures that the load carried by the shelf panel 61 in the z-direction is equally distributed. Hence, the homogeneity of the shelf assembly 100 and the smoothness of the contact surface of the shelf panels 61 are both guaranteed.
[0050] Referring to FIG. 14 and FIG. 15, a cross-sectional view of the shelf assembly 100 taken along section lines A-A and B-B illustrates the connection between the drawer 60, engagement portion 31 and fixing bracket 10. The engagement portion 31 is attached to the fixing bracket 10 with snap fit connections.
[0051] Referring to FIG. 16, the attachment devices 62 are directed in the guiding channel 38 by only partially contacting due to the inclined configuration of the guiding channel 38. Accordingly, the contact between the distal end of the guiding channel 38 that faces the drawer 60 and the attachment devices 62 is diminished to the minimum level. The first point of contact of the drawer 60 with the guiding channel 38 coincides with an orthogonal projection of the retaining groove 11 on a plane enclosing the guiding channel 38. If the guiding channel 38 were not formed as an inclined plane, the drawer 60 would be able to be located at the distal end of the guiding channel 38. In this circumstance, more load would be applied to this connection area as a result of the moment formed there, causing the inclined rear wall 313 of the engagement portion 31 to disengage from a latching portion 121 of the receiving recess 12.
[0052] It is clear from the explanations above that the inclined plane of the guiding channel 38 results in the shelf assembly 100 being more durable and long-lasting.
[0053] Referring to FIG. 13, a stopping hook 36 to be coupled to a lateral surface of the drawer 60 is disposed on the bottom wall 41 of the carrier bracket 30. Moreover, the stopping hook 36 extends at least partly into an interior volume of the drawer 60. The stopping hook 36 limits the drawer 60 from coming out accidentally and prevents disengaging.
[0054] As can be seen most clearly from FIG. 16, the longitudinal protrusion 39 of the carrier bracket 30 is attached to the retaining groove 11 and the attachment between the longitudinal protrusion 39 and the retaining groove 11 prevents an up and down oscillating movement of the shelf panel 61.
[0055] Referring to FIG. 5, the engagement portions 31 are respectively inserted into a corresponding opening 123 disposed on the fixing bracket 10 and the latching portion 121 disposed on fixing bracket 10. The attachment between the engagement portion 31 and the latching portion 121 serves to lessen the lateral movement of the drawer 60.
[0056] Referring to FIG. 8, the engagement portion 31 has the inclined front wall 312 corresponding to the suspension slot 13 disposed on the fixing bracket 10, the inclined rear wall 313 facing the receiving recess 12, a seating protrusion 314 and a tilting recess 311 adjacent to the seating protrusion 314. When the inclined front wall 312 is inserted into the suspension slot 13, the inclined rear wall 313 fits into the receiving recess 12. Accordingly, the movement of the engagement portion 31 is restricted by the peripheral walls of the receiving recess 12. Moreover, the inclined front wall 312 and the inclined rear wall 313 are disposed in the shape of a hook. The tilting recess 311 is configured to allow for a predefined angle of tilt of the engagement portion 31. The engagement portion 31 features a snap-fit structure that allows the carrier bracket 30 to be joined to the fixing bracket 10, while the tilting recess 311 facilitates installation and provides greater flexibility in the case of heavy loading. FIG. 17 depicts a lateral view of the shelf assembly 100 including a drawer 60 and a connection bracket 14. An enlarged view of the detail E taken from FIG. 17 shows the connection between the storage compartment 70 and the carrier bracket 30. Moreover, FIG. 18 depicts that the seating protrusions 314 fit into the corresponding recesses formed on the fixing bracket 10.
[0057] As can be further seen from the exemplary embodiment depicted in FIG. 10, a plurality of retaining protrusions 37 facing the guiding channel 38 are provided, each of which extends perpendicularly to a movement plane where the drawer 60 is pulled away from the cooling device.
