Definitions

  • the present invention relates to a refrigerator, in particular a household refrigerator with a body and a door hinged to the carcass, which together define a storage compartment, and with a sliding in the body in the depth direction slide.
  • the user can hardly estimate the weight, and there is a risk that he will be surprised by the weight of the container at the moment when the container loses contact with the refrigerated goods carrier and he has to hold it alone slips out of his hand, or at least makes an involuntary movement, where there is a risk that the contents of the container is spilled.
  • Object of the present invention is to provide a refrigeration device, which allows a comfortable and safe handling of large and heavy food containers such as beverage crates, large-sized trays, trays, etc.
  • Refrigeration appliance is here understood to mean a domestic refrigeration appliance, that is to say a refrigeration appliance that is used for household management, such as, for example, a refrigerator or a refrigerated freezer combination.
  • a coupling mechanism between the carriage and the door is effective to the carriage in a refrigerator with a carcass and a door hinged to the carcass, which together define a storage compartment, and with a slide movable in the body in the depth direction to hold the door open at a position outside the storage compartment and with the door closed at a position within the storage compartment.
  • the carriage comes to a user automatically when opening the door, and stored on the carriage refrigerated goods can be lifted for removal upwards. This facilitates access to bottles in a box because they are generally accessible only from above.
  • a safe removal of heavy trays, trays or the like is possible because they do not have to be brought forward from the safe state on the slide, but can be lifted directly.
  • the coupling mechanism is preferably housed between a refrigerated goods carrier of the carriage and the bottom of the body. This ensures that movement of the coupling mechanism can not be hindered by refrigerated goods deposited on the carriage.
  • a telescopic extension carrying the carriage is also preferably mounted between the carriage and the floor of the carcass.
  • the carriage expediently comprises an intermediate piece which is mounted on the telescopic extension, and the coupling mechanism is housed in a gap between the intermediate piece and the refrigerated goods carrier.
  • the gap receiving it to a side wall of the body on which the door is hinged, open is expediently the gap receiving it to a side wall of the body on which the door is hinged, open.
  • the coupling mechanism and spacers separating the refrigerated goods from the intermediate piece are mounted.
  • the carriage in the storage compartment at two different, in the width direction of the body staggered positions can be mounted.
  • the carriage is always in those of the two positions, which is adjacent to the side wall facing away from the door hinge of the body.
  • the distance of the carriage to the hinge-side side wall is always greater than to the opposite, and the carriage can extend relatively far even at a small opening angle of the door.
  • the coupling mechanism has a growing with increasing opening of the door gear ratio between displacement of the carriage and rotation of the door.
  • the carriage moves only slowly or not at all, but faster at the end of the opening movement. Therefore, the carriage can start with an opening angle of the door of substantially less than 90 ° with the extension, without causing a collision with the door can.
  • Such a variable transmission ratio can be realized, in particular, with a coupling mechanism which comprises a rod connected to the carriage and to the door by a joint, wherein the door-side joint is behind an imaginary connecting line between the pivot axis of the door and the carriage-side joint when the door is closed ,
  • the door-side joint is expediently offset far from the door into the interior of the storage compartment; Preferably, with the door closed, it is located in the rear two-thirds and preferably in a central third of the storage compartment.
  • the carriage-side joint or the rod must be able to perform an evasive movement, so that the door-side joint a position in front of the connecting line can reach.
  • One possibility for this is to give the carriage a certain freedom of movement to the rear, to the rear wall of the body 1.
  • this solution has the disadvantage that volume of the storage compartment must be kept free to allow the evasive movement of the carriage, and consequently can not be used to accommodate refrigerated goods.
  • One solution which avoids this disadvantage is to provide at least one of the joints a play-containing coupling between the rod and the carriage or the door.
  • the play-containing coupling can be achieved, in particular, by virtue of the fact that at least one of the joints comprises a projection which can slide displaceably into a slot.
  • the hinge may comprise a roller engaging in the slot.
  • the carriage may in particular comprise a storage tray for receiving a crate.
  • it comprises a frame into which containers, in particular large-sized containers, can be latched in a form-fitting manner.
  • Fig. 1 schematically shows a section through a refrigerator according to the invention with a body 1, in which two storage compartments, a normal refrigerated compartment 2 and a basement compartment 3, are divided.
  • the basement compartment 3 occupies the lower third of the body 1. It has a flat bottom without step, since a compressor and a condenser for cooling the compartments 2, 3 are accommodated in a machine room of a base 4 of the apparatus. Both compartments 2, 3 have pivotable doors 5, 7.
  • two telescopic rails 8 are mounted, which carry a movable carriage 6 in the depth direction of the body 1.
  • the upper part of the carriage 6 is designed here as a flat storage tray 9.
  • the storage tray 9 has an edge length of at least 30 x 40 cm. Here it extends essentially over the entire depth of the basement compartment. 3
  • a coupling mechanism 11 engages on the one hand on the door 5 and on the other hand on the carriage 6 in order to move the carriage 6 coupled to the door 7, so that each time the door 7 is opened, the carriage 6 extends so far that when the door 7 is closed completely taken in the tray 3 carriage 6 is completely outside of the door opening angle of about 90 ° of the carriage 6 outside the basement compartment 3 and thus can be accessed freely from the top of a resting on the shelf 9 box 10 from above.
  • Fig. 2 illustrates the principle of the coupling mechanism 11 according to a first embodiment with reference to a horizontal section.
  • the - shown here closed - door 7 is posted on a right side wall 12 of the body 1. It carries at its lower edge a below the storage shelf 9 in the basement compartment 3 engaging rigid arm 13.
  • a coupling rod 14 is connected via a door-side hinge 15 with the arm 13 and a carriage-side joint 16 with the carriage 6 and the storage tray 9.
  • the hinge 16 comprises a pin which rotatably engages in a slot 17 of the carriage 6. In the presentation of the Fig. 2 the pin is located at a front end of the slot 17.
  • the axes of the two joints 15, 16 and a pivot axis 33 of the door 7 form a triangle which has an obtuse angle on the door-side joint 15.
  • the arrangement of the carriage 6 in the compartment 3 is asymmetric, between the side wall 12 and the carriage 6 is a wide gap 20.
  • This gap 20 is required, on the one hand a collision between the carriage 6 and the door 7 during opening and on the other hand, in spite of a protrusion 21 of the door 7 engaging in the compartment 3, which still partly covers the opening of the compartment 3 when the door 7 is open at 90 °, it is possible to fully extend the carriage 6.
  • the in the FIGS. 2 to 6 shown arrangement of the carriage 6 is therefore not suitable when the door 7 is mounted with left stop.
  • the two carriages 6 carrying telescopic rails 8 at the bottom of the basement compartment 3 are arranged mirror images of each other, and on the underside of the carriage 6 are two sets of mounting locations 22 for Fixing the telescopic rails 8 prepared, of which in the representation of Fig. 7 one is occupied by the telescopic rails 8 and the other, as dashed outlines drawn, is free.
  • the illustrated configuration corresponds to the placement of the carriage 6 in the case that the door 7 is mounted with right stop, as in the FIGS. 2 to 6 shown; in a door with left stop are the telescopic rails 8 to the in Fig. 7 free Assembly spaces 22. So comes the gap 20 in one case right, in the other to the left of the slide 6 to lie.
  • Fig. 8 shows the internal structure of the carriage 6 in an exploded view.
  • the storage tray 9 is connected to an identical plate-shaped intermediate piece 23 via elongated spacers 24, 25, which are arranged along a rear or lateral edge of the storage tray 9 and the intermediate piece 23.
  • the lateral spacer 25 is selectively mountable on one of two mounting locations 26, depending on the type of door stop.
  • the configuration shown is for a door with left stop.
  • Two slots 17 allow mounting of the arm 13 and the coupling rod 14 depending on the nature of the door stop in the shown or a mirror-image configuration.
  • Fig. 9 For clarity, in Fig. 9 with solid lines of the carriage 6 and the door 7 in a configuration with right stop, and shown as dash-dotted outline with left stop.
  • the placement of the telescopic rails 8 is the same in both cases; the carriage 6 is separated from the hinge of the door 7 bearing side wall respectively by the gap 20.
  • a simple storage tray 9 for the placement of a crate can be attached to the carriage 6 and a frame for receiving other types of refrigerated goods.
  • Fig. 10 shows such a structure with a frame 27 with two horizontal frames 28, which are shaped to receive a suspended from above container 29, for example of the type known as "Gastro-Norm" type.
  • Recesses 30 on the frame 28 forming struts allow a user to grab under a circumferential brim of the hinged container 29 and lift it so safe.
  • a side wall 34 of the frame extends here in the depth direction of the body 1 adjacent to the intermediate space 20.
  • FIG. 11 shows by means of one of the FIGS. 2 to 6 analogous section a second embodiment of a coupling mechanism between the door 7 and carriage 6.
  • a rigid arm 13 projects from the door 7 into the compartment 3, and a coupling rod 14 is connected to the arm 13 and the carriage 6 via joints 15, 16 connected.
  • the door-side hinge 15, which has a slot and a pin, which move in the initial phase of an opening movement of the door 7 against each other and thus allow an opening of the door 7 without simultaneous retreat of the carriage 6.
  • both joints 15, 16 of the coupling rod 14 are free of play, and instead the coupling rod 14 itself is divided into two telescopically mutually displaceable sections 31, 32 to allow a temporary compression of the coupling rod 14 at the beginning of an opening movement of the door 7.
