Definitions

  • the present invention relates to a door bearing with a support arm for attachment to a door frame and a bearing pin for insertion into a bore in a door, the door bearing being intended in particular for use on doors of refrigeration appliances, and to a method for mounting a door, in particular with this Door storage is feasible.
  • the doors of refrigeration appliances and their bearings are generally designed in such a way that they are suitable for hanging a door with either a right or left stop without the need to replace parts. This enables the manufacturer of the refrigeration devices, doors and bearings to be manufactured in a uniform manner, a decision regarding the position of the door stop only having to be made by the user when the refrigeration device is installed and, if necessary, can also be subsequently revised there.
  • Conventional door mounts generally include a metal support arm, e.g. can be punched out of a strong sheet metal, and to which a likewise metallic, cylindrical bearing journal is welded.
  • a metal support arm e.g. can be punched out of a strong sheet metal, and to which a likewise metallic, cylindrical bearing journal is welded.
  • you will generally first attach the lower support bearing to the door frame of the refrigerator, put the door over the bearing journal of the lower door bearing with a hole provided for this purpose, and the bearing journal into a corresponding hole in the upper one Insert the edge of the door and finally attach the upper door bearing to the door frame. If the door is tilted in the meantime during this procedure, this can damage the lower door bearing and in particular the lower hole in the door.
  • the assembly of the door or the change of the door stop is therefore not easy for inexperienced people to carry out and involves risks.
  • the object of the present invention is to provide a door bearing of the type specified at the outset or an assembly method with which even inexperienced persons can easily assemble a door or change its stop.
  • the object is achieved in that the support arm has a bore for the positive reception of a base portion of the bearing pin, and that the base portion and the arm are equipped with locking elements for hooking the bearing pin on the support arm.
  • a door bearing constructed in this way initially only allows the support arms to be attached to the door frame for mounting the door. As soon as this has been done, a person can hold the door in a suitable position between the support arms, so that the bearing pins can be pushed through the holes in the door bearings into the holes in the door and locked in place on the bearing pins.
  • Pushing in and locking the bearing pins only takes a short time, so that the risk of the door tipping unintentionally is relatively low during this time.
  • the journals can be pushed in while the door is held against the door frame, while in the conventional method described above the door generally has to be held in the open position in order to keep the access necessary for fastening the upper door bearing on the door frame free.
  • a first embodiment of the door bearing provides that the latching elements comprise an edge on the support arm and a flexible clamp with a leg that can be spread from the base section when the base section is inserted into the bore of the support arm and that carries a nose for engaging behind the edge.
  • the support arm and the leg are preferably shaped such that a tool for releasing the nose from the edge between the leg and the support arm can be inserted.
  • the latching elements comprise at least one cutout in the bore and at least one leg of the base section which can be bent toward the axis of the bore when the base section is inserted into the bore of the support arm and which carries a nose for engaging in the cutout.
  • the recess extends only over part of the circumference of the bore, and that the base section is rotatable in the bore in order to remove the nose from the To displace recess. That is, by rotating the base section, the latching between it and the support arm is released, and the support arm and bearing journal can be separated from one another.
  • the base section preferably has a recess at one end facing away from the bearing journal for the form-fitting reception of a turning tool such as a screwdriver, an Allen key or the like.
  • the bearing journal and the base section can advantageously be formed in one piece from a plastic material, in particular a fiber-reinforced plastic material.
  • a plastic material in particular a fiber-reinforced plastic material.
  • the bearing journal it is also entirely possible for the bearing journal to be made of metal and the base section to be made of the plastic material, and for the two to be firmly joined together to form a single part.
  • the support arm can be formed from a plastic material, in particular a fiber-reinforced plastic material.
  • a roller bearing is preferably arranged to support the door around the bearing journal.
  • this roller bearing is expediently an axial bearing.
  • a barrel storage facility is preferred due to its low overall height.
  • such a rolling bearing is constructed from two rings which can be rotated relative to one another with the aid of rolling bodies arranged between them.
  • a ramp-shaped ring section is assigned to each rolling element.
  • Such a design of the rings means that the axial expansion of the roller bearing increases and the door is raised as the door rotates. This effect can be used to exert a restoring force on the door in the direction of its closed state.
  • the number of rolling elements in such a bearing is preferably limited to not more than three. This enables the door bearing to rotate freely by almost 120 °.
  • the rings can have at least one depression for each rolling element, in which the rolling elements engage at the same time, and which thus define a latching position of the door.
  • means for restricting the freedom of rotation such as a mechanical stop, are expediently provided.
  • the roller bearing is expediently designed as a radial bearing, in particular as a needle bearing.
  • the door bearing can also be equipped with a closing body which can be moved by a spring and which can be brought into or out of an engagement position with a counter body by rotating the door, the engagement position fixing the locking position of the door and outside of the engaged position, the door is freely rotatable.
  • a guide for the movement of the closing body is preferably firmly connected to a ring of the rolling bearing.
  • the ring and the guide can be connected to form a housing which essentially closes off the bearing from the outside.
  • the support arm can be provided with a protruding stop for fixing its position on the door frame.
  • the closing body it is expedient for the closing body to be arranged on a side of the stop facing away from the door frame.
  • the counter body is removed from the bearing journal as far as possible on the support arm, so that the closing body and the counter body can exert a relatively large torque on the door given the shape and strength of the spring.

  • the support arm 3 has the shape of an inverted U-profile over the major part of its length; with a massive head section 5 through which a bore 6 extends vertically.
  • a stop 4 which projects to the sides and upwards, is formed on the inverted U-shaped section of the support arm 3 and defines the depth to which the support arm 3 can be inserted into the opening of the housing.
  • a bearing journal 7 is received in a form-fitting manner in the bore 6.
  • the bearing pin 7 is composed of a pin 8 projecting upward above the support arm 3 and a base section 9.
  • the base section 9 is constructed from a cylindrical section 10, the diameter of which is somewhat larger than that of the pin 8, and a bracket 11 which initially extends horizontally from the cylindrical section 10 and then merges into a vertical leg 12 with a nose 13 formed thereon and facing towards the cylindrical section 10.
  • the bracket 11, in particular its leg 12, is flexible in itself, so that when the bearing pin 7 is inserted from below into the bore 6, the nose 13 can first be elastically spread outwards, in order to then when the bearing pin 7 reaches its end position in the Bore 6 reached to engage behind an edge 14 formed at the head end 5 of the support arm 3 (see FIG. 2) and to hook the bearing journal 7 so firmly.
  • An inclined surface 15 formed at the head end 5 of the support arm 3 is provided in order to facilitate the insertion of a tool, such as a screwdriver, between the head end 5 and the clamp 12 and thereby to detach the nose 13 from the edge 14 again. When this has been done, it is possible to pull the bearing pin 7 down out of the bore 6 and then unhook the door 2.

Between the two legs 32, a recess 41 is formed in the cylindrical section 30, which is provided here for receiving an Allen key with a hexagonal cross section. However, the recess could also be designed to accommodate other types of screwdrivers, for example as a simple slot or as a cross slot. The meaning of this measure becomes clear when looking at FIG. 5, which shows a top view of the support arm 23 with the bearing pin 27 inserted into the bore 26.

If the rolling elements 48 are located on these flat sections 52 when the door is open, no restoring force acts on the door 2, and the state of the maximum door opening is therefore stable.
