Definitions

• the present invention relates to a door mounting bracket for the rotatable suspension of a door of a cabinet-type household appliance, in particular a refrigerator or freezer.
• Conventional door mounting brackets of this type comprise a support arm to be fastened to the housing of the household appliance, which carries at one end a substantially vertically projecting pin.
• the pin is intended to be inserted into a hole in the door and thus to define a vertical pivot axis for the door.
• this pin is a solid metal pin which is inserted into a bore in the likewise metallic support arm and is welded or riveted therein.
• the door suspended from such a door mounting bracket can reach a considerable weight if it is, for example, a refrigerator door with refrigerated goods racks, which are generally fastened to the inside of the door, which are filled with comparatively heavy refrigerated goods such as beverage bottles.
• a refrigerator door with refrigerated goods racks which are generally fastened to the inside of the door, which are filled with comparatively heavy refrigerated goods such as beverage bottles.
• the housings of such refrigeration devices tend to become ever lighter, since for the manufacture of the housing walls increasingly heavy metal sheets are replaced by lightweight plastics and the refrigeration machines can be built increasingly smaller and thus lighter. If the housing of such a refrigerator is only slightly loaded, but the door is full, this development can, in extreme cases, result in the stability of the device being endangered and the device tending to tip over when the door is opened.
• the door bearing bracket according to the invention can be provided in a particularly simple manner with a height-adjustable foot in that the pin part of this foot is accommodated in a cavity of the bearing journal. This feature frees the need to provide a corresponding cavity in the housing of the refrigerator itself, which simplifies the manufacture of the housing.
• the manufacture of the door bearing bracket is also simplified in that the pin part of the foot also serves as a support for the bearing journal.
• the static load-bearing capacity of the foot allows the bearing pins slid onto it to be less statically demanding, e.g. made of plastic.
• the height adjustability of the foot is achieved in a simple manner with the aid of a threaded bore of the support arm aligned with the bearing journal and a thread of the pin part engaging into the hollow space of the bearing journal through this threaded bore of the support arm.
• the cavity of the bearing pin receives the pin section in the radial direction essentially without play. Because the pin part is at least essentially free of play to match the cavity of the bearing pin, the door can also be mounted precisely and without play.
• the threaded bore is preferably formed in a protruding neck of the support arm. This enables the formation of a thread of sufficient length for a high load-bearing capacity of the foot, even if the material of the support arm does not have a thickness corresponding to this length.
• the projecting neck is molded in one piece from the material of the support arm, e.g. formed in the manner of a thread passage.
• the bearing pin is connected to the support arm via a plug-in shoe which can be pushed onto an end section of the support arm and can be locked thereon.
• This plug-in shoe which preferably consists of a solid plastic material, at the same time allows a visually appealing covering of the end section of the Support arm, so that there is no need for complex surface treatment, painting or the like of the support arm. If the support arm is provided with the nozzle mentioned above, this can also serve as a locking point for a tongue of the plug-in shoe.
• the plug-in shoe and the bearing pin are preferably formed in one piece from plastic.
• the invention also relates to a household appliance which has at least one door bearing bracket as defined above.
• Figure 1 is a perspective view of a door bracket according to the invention with support arm, bearing pin and adjustable foot.
• FIG. 2 shows a perspective view of the lower region of a refrigeration device housing with a bearing journal mounted thereon;
• Figure 3 shows the same door bearing bracket with the omission of the bearing pin.
• Figure 4 shows the door bearing bracket with the bearing journal shown in section.
• Figure 5 is a perspective view of the door bracket from below, with the foot omitted.
• Fig. 6 is a perspective view of an upper door bracket according to the invention.
• FIG. 1 shows an overall view of a lower door bearing bracket according to the invention. It is constructed from a support arm 1 bent from strong sheet steel, a plug-in shoe 2 made of plastic, which is attached to one end of the support arm, from which a bearing pin 3 protrudes vertically upwards, which is provided to engage in a corresponding bearing bore on the underside of a door.
• a height-adjustable foot 4 of which only a hexagonal base section, which is supported on the installation level, can be seen in the figure, projects downward from the support arm 1.
• the support arm 1 has an approximately U-shaped cross section, as a result of which the support arm 1 is given a high degree of flexural rigidity by the two U-profile legs 19.
• An end section of the support arm 1 opposite the plug-in shoe 2 is shaped into a short, narrow tongue 6, which also has a high degree of flexural rigidity due to an impressed depression 8.
• the tongue 6 is provided for positive insertion into an eyelet 20 of a refrigerator housing.
• Fig. 2 is a perspective view of the lower portion of a refrigerator housing, illustrating the attachment of the door bracket to the housing.
• a hole 7 formed approximately centrally on the support arm 1 is provided to receive a screw with which the support arm 1 is screwed onto the housing from below. For the fixed mounting of the support arm, it is therefore sufficient to first insert its tongue 6 into the eyelet of the housing and then to screw it tight through the bore 7.
• the bearing pin 3 engages in the already mentioned bearing bore on the oblique underside of a door 21; the flattened end of the bearing journal 3 bears the weight of the door 21.
• FIG. 3 is a view of the door bearing angle in the same perspective as FIG. 1, but with the plug-in shoe 2 and the bearing journal 3 connected to it omitted in order to be able to show the foot 4 more completely.
• a pin section 9 projecting vertically upward from the base section 5 is provided with an external thread which engages with an internal thread of a bore 10 in the support arm 1 and via which the weight of the refrigerator is transferred to the base 4. By turning the foot 4, the height of the support arm 1 can be adjusted over a standing area.
• Fig. 4 is again a perspective view of the door bracket angle in the same perspective as Figs. 1 and 2, in which, however, the plug-in shoe 2 and the bearing pin 3 are shown cut open in the longitudinal direction of the support arm 1.
• the bearing pin 3 which is formed in one piece with the plug-in shoe 2 has a cavity 12 which is open at the bottom and into which the pin section 9 engages.
• the outside diameter of the pin section 9 corresponds to the inside diameter of the cavity 12 with a small tolerance.
• the bearing journal 3 thus prevents the pin section from tilting unintentionally. Section 9 and thus protects the thread of the pin portion 9 and the bore 10 from damage.
• the essentially play-free application of the bearing pin 3 to the pin section 9 also creates the prerequisite for a play-free mounting of the door 21 on the bearing pin 3.
• Fig. 5 shows a perspective view of the door bracket from below, with the foot 4 is omitted.
• the bore 10 of the support arm 1 is extended on the underside thereof by a connecting piece 13 which is formed from the material of the support arm 1 by the thinning out of an originally smaller bore.
• This nozzle 13 has a double function.
• it allows the internal thread of the bore 7 to be made considerably longer than it corresponds to the actual material thickness of the support arm 1, so that the foot 4 can be loaded with high weight without risk of damaging the thread, and on the other hand it serves as a detent stop for a flexible tongue 14 of the plug-in shoe 2 and keeps it fixed on the support arm 1, even if the pin section 9 of the foot does not engage in its cavity.
• the starting point of the tongue 14 is a bridge 15, which connects two side flanks of the plug-in shoe 2 below the support arm 1 to one another and thus increases the rigidity of the plug-in shoe and its resilience due to tilting moments acting on the bearing journal 3.
• the idea of fastening the bearing journal to the support arm with the aid of a plug-in shoe can also be transferred to the upper door bearing bracket of a refrigerator door.
• a support arm 1 ′ with a tongue 16 and a base section 17 angled from the tongue 16, in which a plurality of bores for screwing to a refrigerator unit housing are formed.
• the plug-in shoe 2 ' has a closed top and bottom;
