Description

(1) Further details and advantages result from the following embodiment described with reference to the Figures. The Figures show:

(2) FIGS. 1A-1D: a refrigerator and freezer unit in accordance with the invention with protection against tilting; and

(3) FIGS. 2A-2D: the corresponding unit in its end position without protection against tilting.

(4) The unit shown in the Figures is generally marked by the reference numeral 1. It is a built-in refrigerator unit, i.e. a unit that is to be placed in an installation niche of a kitchen and is to be secured there.

(5) It comprises a body 2 that surrounds a cooled inner space 3. The body 2 furthermore has a base 4 beneath the cooled inner space 3 and the machine space and the ventilation apparatus among others are located therein. A door leaf 5 to close the inner space 3 is connected in an articulated manner in front of the front-side opening of the inner space 3 at the body 2 and is pivotable about the vertical axis A. Pockets are attached to the inner side of the door 5 to form an additional storage area for refrigerated goods.

(6) The unit 1 comprises four rollers 6, two front rollers and two rear rollers, at the bottom of the unit body 2, i.e. at the lower side of the base 4. These rollers 6 define the corner points of a rectangular footprint of the unit 1. The unit 1 can be pushed along the floor on the rollers 6 before its installation into the niche provided for this purpose. It can be recognized that the normal footprint does not extend up to the plane B of the opening toward the inner space 3 and by no means up to the front plane C of the closed door 5. There is therefore a risk that the unit 1 will tilt to the front on a comparatively small influence of force. This applies all the more on an unintended opening of the door. The width of the door 5 is within the same magnitude as the depth of the unit 1 and the door has a not insignificant weight due to the door pockets, the heat insulation, etc. The center of gravity of the unit 1 is therefore displaced on an opening of the door at least to close to the front edge of the footprint defined by the rollers 6.

(7) Four adjustable feet 7, two front adjustable feet and two rear adjustable feet, are furthermore attached to the bottom of the unit body 2, i.e. to the lower side of the base 4, in addition to the rollers 6. All four adjustable feet 7 each have a platform 8 and a threaded bar 9 by which the platform 8 (cf. FIG. 2C) is connected to the body 2. The threaded bars 9 are received in bores at the body 2, with the bores having an internal thread such that the adjustable feet 7 can be moved in and out by a rotary movement.

(8) The rollers 6 are preferably also vertically adjustable.

(9) The adjustable feet 7 are retracted in the state of the unit 1 before the installation at the final installation site, i.e. in the state shown in FIG. 1A, so that a displacement of the unit 1 on the rollers 6 is not impeded. The adjustable feet 7 are only extended by rotation when the unit 1 is to be fixed at the installation site and replace the rollers 6 as floor-contacting parts. The footprint is thereby extended and the risk of tilting is reduced or removed. Depending on the situation, the unit 1 can additionally be fixed by an installation bracket, for example, at the installation location.

(10) To prevent tilting of the unit 1 when the adjustable feet 7 have not yet been extended and the footprint of the unit 1 is defined by the rollers 6 (as in FIGS. 1A-1D), protection against tilting is provided in the form of two L-shaped section rails 10 that are clamped between the platforms 8 of the front adjustable feet 7 (in the installed state) and the bottom of the unit body 2 or of the base 4. To be able to clamp the rails 10 in a stable manner between the adjustable feet 7 and the bottom of the body 2, an elongated hole 12 open to the margin is provided at the rear side of the rails 10.

(11) Starting from the front adjustable feet 7, the rails 10 extend to the front in a straight manner, with the end point 11 of the rails 10 being disposed in front of the plane B of the unit opening and approximately at the level of the frontal plane C of the closed door 5 (cf. FIG. 1B). The rails 10 are located at the level of the retracted adjustable feet 7 so that they do not contact the floor. A displacement of the unit 1 on the rollers 6 is thus not impeded. The rails 10 only extend close to the floor so that the tilt movement is immediately taken up by the rails 10 in the event of a tilting of the body 2 to the front, for example after an unintended door opening. The tilting point is thus displaced from the front rollers 6 to the front end 11 of the rails 10. The profiled L-shaped design of the rails 10 provides them with the required stability so that they do not bend on a tilting of the unit 1, but remain straight and can prevent a tilting over of the unit.

(12) On the installation of the unit 1 at the final installation site and on the moving out of the adjustable feet 7, the clamping connection with the rails 10 is released, as is shown in FIGS. 2A-2D that show the unit in different perspectives. The rails can then simply be removed without a further workstep being required. In comparison with the state in FIGS. 1A-1D, the adjustable feet 7 are moved out, with the case being covered by the invention that all the adjustable feet having been moved or rotated outward by the same amount or also to different extents.

(13) In the representations in accordance with FIGS. 1A-1D, the protection against tilting is secured, i.e. fixed, by a clamping connection with the adjustable feet 7. This is not the case in the arrangements in accordance with FIGS. 2A-2D. Since the adjustable feet 7 have been moved out, the clamping connection is dispensed with and the security against tilting or the rails can simply be removed.

(14) The protection against tilting is preferably present ex works and up to the final installation at the customer's.

(15) The protection against tilting is preferably only removed after the installation of the unit, e.g. into a kitchen niche, or after the securing of the unit by an installation bracket (wall, floor, . . . ).

(16) The protection against tilting does not necessarily have to cooperate with the adjustable foot or feet.

(17) It is also conceivable (alternatively or additionally) that the protection against tilting is arranged at the unit by means of a separate fastening, such as by a screw connection. It can also be pushed into the unit or into a holder at the unit.

(18) An (additional) roller can be attached to the protection against tilting to protect the floor or a runner can be attached.

(19) The protection against tilting can have an L section or any other desired shape.
