Definitions
- the present invention relates to a door for a refrigerator, particularly for a refrigerator of the cupboard type, provided with profiled elements for releasably securing a shaped inner door or "counterpanel” to its inner surface.
- the inner side of the door of an appliance of this type is provided with a peripherally extending sealing gasket and an inner door panel shaped to support bottles, containers or other goods to be refrigerated.
- sealing gasket and the inner door panel are releasably secured to the door so that they can be substituted in case of damage.
- One solution for so securing the gasket and inner door panel provides for the gasket to be fitted onto the edges of the inner door panel which is then secured to the body of the door by means of screws.
- This solution permits the inner door panel to be mounted in an automatized operation by simple pressure, and if so required to be dismounted by resiliently bending the retaining lips apart.
- the retaining force of the resilient lips may sometimes be surmounted by the inertial forces exerted on the door as it is closed by the inner door panel and the goods supported thereby, so that the inner door panel may strike the door frame of the refrigerator with a sometimes considerable force.
- the retaining lips are subjected to fatigue after extended use so as to loose their initial resiliency, or that they are irreparably damaged on dismounting of the inner door panel.
- edge portions of the inner door panel as well as the resilient retaining lips have to be designed with an abundant thickness so as to prevent one or the other from yielding to the strains and stresses acting thereon.
- Another object of the invention is the provision of a door of the type defined above which permits an inner door panel to be releasably, and thus replaceably, mounted thereon without the use of additional fastener elements such as screws, fastener strips and the like.
- a door for a refrigerator particularly a refrigerator of the cupboard-type for domestic use, comprising a panel formed of foamed plastics material and enclosed between an outer lining sheet and an inner cover sheet and provided at its inner surface with a peripheral moulding embedded in said panel and formed with respectve seats for releasably retaining the foot portion of a sealing gasket and an edge portion of an inner door panel, said door being characterized in that said seat for releasably retaining said inner door panel in said moulding is of V-shaped cross-sectional configuration having its open side partially closed by a ledge, and in that said inner door panel is formed with rim portions projecting towards the interior of the door and located adjacent the fastening edge portions of the inner door panel, said rim portions being likewise bent into a V-shaped configuration for snap-engagement with said V-shaped seat of said moulding, so that said inner door panel is clampingly mounted on said door by constraining said rim portions between the inner edge of said ledge and the inner
- Shown in fig. 1 is across-sectional view of a part of a vertical door 5 of a cupboard-type refrigerator, comprising in a per se known manner an outer sheet metal liner 6 and an inner covering sheet 7 made for instance of cardboard, a foamed plastics material 8 being injected therebetween for thermal insulation and mechanical rigidific- ation of the overall structure.
- Adjacent the inner peripheral border of door 5 insulating panel 8 carries an arrangement of mouldings 9 embedded therein and bonded to one another so as to form a substantially rectangular frame adapted to resiliently receive and releasably retain a foot portion 10 of a sealing gasket 11 and a rim portion 12 of an inner door panel 13 formed of a plastics material in a configuration permitting it to support bottels and other food containers.
- each moulding 9 has a horizontal outer lip 14 partially overlapping sheet metal liner 6, and a vertical inner lip 15 projecting above inner covering sheet 7 of door 5.
- Adjacent outer lip 14 in the direction towards inner lip 15 moulding 9 is formed with a first recess 16 forming a seat for foot portion 10 of gasket 11, and adjacent thereto with a second recess 17 forming a seat for rim portion 12 of inner door panel 13.
- Seat 17 is of V-shaped cross-sectional configuration, with its open side partially closed by a ledge 18 defining a restricted entrance for receiving and retaining rim portion 12 of inner door panel 13.
- Edge portion 12 itself is likewise bent backwards into a V-shaped configuration conforming to that of seat 17 and having a suitably dimensioned outer leg 19 for engaging the lower surface of ledge 18 from within seat 17.
- the inner door panel 13 may be mounted by simply exerting pressure on its peripheral border region.
- the backfolded rim portion 12 of inner door panel 13 is introduced into the restricted entrance of seat 17 while being guided by upstanding lip 15, until outer leg 19 has passed ledge 18 and is restored to its relaxed configuration as shown in figs. 1 and 2, so as to engage the lower surface of ledge 18 from within seat 17.
- the region for the storage of foods is usually bordered by shelves or ridges projecting towards the interior of door 5 and formed of an outer web 20 extending from the junction between the door and the inner door panel substantially at right angles to the plane of the door, a narrow end face 21 parallel to the plane of door 5, and an inner web 22 connected to the bottom wall 23 of the inner door panel.
- outer web 20, inner web 22 and end face 21 are configured to create a biasing force between the point of support of inner door panel 13 on inner covering sheet 7 of door 5 and the point of engagement between outer leg 19 of rim portion 12 and the inner surface of ledge 18, whereby webs 20, 22 and end face 21 are always kept under tension so as to ensure a sufficiently rigid engagement of inner door panel 13 below ledge 18 of moulding 9.
- inner door panel 13 may in fact be carried out by pulling it away from the remainder of door 5 with sufficient force to bend or straighten outer leg 19 of rim portion 12 so as to release it from engagement with ledge 18 of moulding 9.
- inner door panel 13 may be formed with suitable gripping portions.
- the profile of the inner door panel Adjacent the lower corners of the door the profile of the inner door panel is shaped in the manner shown in fig. 3, so that the weight of the inner door panel does not rest on the outer leg 19 of the lower rim portion, as this would lead to a reduced stability of the connection and a continual and undesirable load on this outer leg portion.
- the lower end portion of inner door panel 13 adjacent the corners of the door is formed with a planar rim 24 abutting the edge 25 of ledge 18, so that the weight of the inner door panel and any goods carried thereby rests on ledge 18 which is sufficiently strong for this purpose. In this manner the mounting of the inner door panel on the door is stabilized.
- the invention enables the inner door panel 13 to be mounted on door 5 by a simple process not necessitating any manual operations and thus capable of being carried out in a fully automatic manner so as to facilitate the overall assembly operation.
- a further advantage of at least similar importance results from the fact that the resilient elements required for mounting the inner door panel on the door are exclusively associated with the former, so that it may be replaced without having to replace the entire door.
