Definitions

  • the invention relates to a refrigerator and / or freezer with a drawer or a drawer for holding refrigerated and / or frozen goods.
  • a refrigerator and / or freezer in its interior which serves to hold refrigerated and / or frozen goods, usually includes a number of mostly horizontal storage and storage areas, a number of drawers or drawers, storage compartments arranged in the appliance door and a door rack for bottles or similar goods.
  • the drawer or drawer which is usually arranged in a part separated from the rest of the refrigerator and / or freezer compartment, is usually located on the bottom of the device. Because an inspection of the drawer or the drawer due to an upper cover surface usually served with refrigerated goods or due to a non-transparent cover surface, such as. B. the door rack, it is difficult to see which refrigerated goods are currently stored in the drawer or drawer. Due to the comparatively low arrangement of the drawer or drawer, the filling and removal of refrigerated goods is also comparatively difficult.
  • the invention is therefore based on the object of specifying a refrigerator and / or freezer with a drawer or a drawer which is particularly easily accessible.
  • the drawer or drawer is particularly easy to access if it is extended with a tilting movement.
  • a technically particularly inexpensive and easily realizable embodiment with regard to the automatic extension is given when a spring mechanism is tensioned when the drawer or drawer is closed.
  • the mechanical energy stored in the spring is used to open the opening / closing mechanism for the extension movement of the drawer or drawer.
  • a particularly simple and practical storage of the drawer or drawer results if the relevant storage is provided on a slide rail.
  • the automatic extension movement is damped, preferably by a silicone gear brake.
  • a particularly simple opening / closing mechanism is obtained when the mechanism is triggered by a brief pressure movement in the direction of entry. This pressure movement is comparable to pressing a switch and is therefore particularly unproblematic with regard to triggering.
  • a particularly good use of the space available for shelves on the appliance door results if the drawer or drawer is arranged below a door rack on the appliance door.
  • Fig. 1 shows a front view of a section of a door 2 for a cooling device not shown here.
  • the lower part is shown in the detail this door 2, which has a door rack 4 and a drawer 6 arranged under the door rack 4.
  • the door rack 4 has elongated side walls 8, which are designed to accommodate a slide rail 10, a silicone gear brake 12 and a securing bolt 14 on both sides.
  • a toothed / slide rail 16 is injection molded on both sides of the drawer 6 and a bolt 18 is fixedly mounted in a hole receptacle (not shown) on the drawer 6.
  • a stop 20 is injection molded onto the slide rail 10 in the front part. This stop 20, in conjunction with the bolt 18, prevents the drawer 6 from being completely pulled out, the travel path for the drawer 6 being limited at the same time, as shown in FIG. 2.
  • the toothed / slide rail 16 molded onto the drawer 6 does not have teeth 22 in the rear area, but is designed to be smooth there. This area serves to transmit power to the safety pin 14. When the drawer 6 is in the extended state - as shown in FIG. 2 - it is supported on the safety pin 14, preventing the drawer 6 from tipping out completely.
  • the securing bolt 14 is fixedly mounted on the side wall 8 of the door rack 4.
  • the securing bolt 14 is necessary because the drawer 6 also performs a downward tilting movement when it is extended, so that an intervention in the drawer in the extended state is particularly user-friendly. This tilting movement is achieved by the circular rail-shaped slide rail 10 and the tooth / slide rail 16 which are opposite to it.
  • FIG. 3 shows the side view according to FIG. 2 with the drawer 6 pushed in.
  • the drawer actually Covering side wall 8 and the parts arranged therein on the side wall 8 and on the drawer 6 are indicated by dashed lines and have not been provided with reference numerals here for reasons of clarity.
  • the automatic pulling out of the drawer 6 is brought about by a slight pressure movement of the drawer 6 against the rear wall of the door rack 4 (cf. arrow 22).
  • a latching hook 24 arranged on the rear part of the drawer 6 presses against a pressure plate 26 in an opening / closing mechanism 28. Because of this pressure pulse, the opening / closing mechanism 28 is actuated, which leads to the latching flanks 30 of the mechanism 28 Release locking hook 24.
  • the drawer 6 moves out automatically with the aid of the relaxation movement of an expansion spring 32.
  • the spreading spring 32 is shown in Fig. 3, and is there in the tensioned state because the drawer 6 is in the retracted state.
  • the spreading spring 32 is fixed in a receptacle 34 on the door rack 4 and movably on the drawer 6 by means of a roller 36.
  • opening and closing the spreading spring 32 is guided laterally between ribs 38 by means of the roller 36.
  • The. Ribs 38 are molded onto the drawer 6.
  • the opening speed of the drawer 6, caused by the spring force of the spreading spring 32, is delayed by the silicone gear brake 12.
  • the delay is caused by the engagement of a gear 42 with the tooth / slide rail 16 through which the entire drawer is guided.
  • FIG. 4 shows the closing and opening of the opening / closing mechanism 28 on the basis of three positions a), b) and c).
  • the drawer is closed against the force of the spreading spring 32.
  • the drawer 6 is locked in the course of the closing movement by a pushing movement of the drawer 6 and thus of the latching hook 24 against the door rack 4, the latching hook 24 being inserted into the opening / closing mechanism 28 becomes.
  • the latching flanks 30 also slide into the opening / closing mechanism 28 and, with the undercuts provided on the latching flanks 30, lock the latching hook 24 in the end position, which is shown in b).
  • Position b) shows the state during the closing process immediately shortly before the latching hook 24 touches the pressure plate 26.
  • Position c) shows the state shortly after a brief pressure movement of the drawer 6 in the direction of insertion 22.
  • the latching flanks 30 then move out of the opening / Closing mechanism 28 out and release the locking hook 24 and thus the drawer 6, which automatically moves out against the direction of arrow 22 by the spring force of the spring 32.
  • the opening / closing mechanism 28 is fixedly mounted in a receptacle 40 with undercuts 44 on the door rack 4.
  • the principle described here of arranging the drawer 6 below the door rack 4 in a refrigerator door 2 can of course also be applied to other drawers or drawers arranged in the interior of the refrigerator. It is also possible to equip drawers or drawers of freezers with such a mechanism.
