Definitions

  • the present invention relates to a refrigerator and / or freezer, in particular a refrigerator and / or freezer, with at least one interior and at least one lid, with which the interior is closable.
  • a refrigerator and / or freezer with the features of claim 1. Thereafter, it is provided that a refrigerator and / or freezer, in particular a refrigerator and / or freezer, is provided with at least one interior and with at least one lid, wherein the interior is closed with the lid. Further, at least one damping element is provided, which indirectly and / or directly delays the closing operation of the lid.
  • An indirect delay by the damping element may be that the damping element is not directly in engagement with the lid of the refrigerator and / or freezer, but rather that separate means are provided by means of which one or more damping element can be triggered. Equally well, however, it may be provided that one or more damping elements act directly, ie directly on the closing operation of the lid.
  • the refrigerator and / or freezer according to the invention has the advantage that a hard striking the lid and a possible possible damage to the lid or related components of the refrigerator and / or freezer can be avoided. Furthermore, the noise development is significantly reduced by the impact noise. Another important advantage is that the risk of injury by z. B. squeezing of fingers or limbs can be reduced because, for example, a damped closing action reduces the action of a closing lid on optionally located in the gap limbs. Furthermore, the soft closing of the sliding cover gives the user high quality and comfort.
  • the at least one damping element is integrated in the cover.
  • An integration in the lid allows a simple and highly accurate positioning and adjustment of the at least one damping element. Further, during assembly, the assembly consisting of covers with one or more damping elements can be mounted quickly and precisely.
  • the at least one cover is a sliding cover. It is possible that the lid lie in two mutually parallel planes.
  • the covers lie in an end position in a common plane, while in a second position, e.g. be pushed over each other in the open position by swinging a lid over the other lid. This can be done for example by means of appropriately trained guide rails. In principle, however, it is also possible for the lids to be displaceable relative to one another in two mutually parallel planes.
  • lids are arranged horizontally or approximately horizontally displaceable.
  • An advantageous embodiment further consists in that the lid has a self-closing function. This is particularly advantageous if the user wants to remove bulky items to be refrigerated, for example, with both hands the refrigerator and / or freezer and he no longer has to worry about the closing of the refrigerator and / or freezer after removal. Such a function also has the advantage that icing of the device is additionally prevented.
  • At least one cable pull or at least one lever is provided, which excites or triggers at least one damping element.
  • a damping element for example in the bottom region of the refrigerator and / or freezer, which indirectly delays the closing operation of at least one lid by means of at least one cable or at least one lever.
  • the damping element comprises return means, by means of which the damping element is traceable to a zero position or initial position of the damping element.
  • return means may for example consist of a mechanism which resets the damping element by means of gas pressure or a spring.
  • the restoring means returns the damper piston to its initial position, so that the piston rod is extended in order to have a damping effect.
  • the at least one damping element is integrated in the body of the device.
  • the damping elements may be mounted at a location where the lid abuts.
  • a cover frame is provided, wherein the cover frame is limited in the opening of the interior.
  • a cover frame is placed on the body of the refrigerator and / or freezer. This makes it possible to manufacture the body and cover frame with different tolerances, which cost advantages can be realized.
  • guide rails may be formed in the cover frame into which the cover is inserted and thereby displaceably guided.
  • the at least one damping element is integrated in the cover frame.
  • the damping element acts dampening away over a damped closing path of the cover, wherein the damped closing path is designed on the basis of the dimensions of human extremities.
  • the damping element is an oil damper and / or a combined oil gas pressure damper and / or a gas pressure damper.
  • the choice of the damping element of the three aforementioned damping systems depends on the required damping effect, but also on the permissible weight of the damper.
  • a further advantageous embodiment is that the lid has guides, by means of which the cover is guided displaceably in the cover frame and that the damping elements are respectively arranged in the guides to the side of the lid, which abuts with the cover frame.
  • the at least one damping element can have a damping effect over the entire opening path or partially along the opening path of the at least one cover.
  • damping elements in the region of one or both end positions of the at least one cover have a damping effect.
  • dampening effect the fact is taken into account that it can not only come when closing the lid to injuries, but also at a z. B. too impetuous opening the lid. Also here it can come to the crushing of extremities.
  • Fig. 1 shows a refrigerator and / or freezer according to the invention in one embodiment as a refrigerator and / or freezer 10.
  • the refrigerator and / or freezer 10 is carried out by means of rollers 16 which are mounted on the bottom side of the refrigerator and / or freezer 10, mobile , On the body of the refrigerator and / or freezer 10 while a cover 12 is placed by two lids 20 are guided displaceably.
  • the lid 20 are designed as two mutually displaceable lid 20, wherein the lid 20 are in the closed state of the refrigerator and / or freezer 10 next to each other.
  • the cover 20 are arranged horizontally displaceable.
  • the cover frame 12 and the lid 20 are designed curved so, the front edge of the cover frame 12 is lower than the rear edge of the cover frame 12.
  • FIG. 1 shown embodiment of a refrigerator and / or freezer 10 is an embodiment in which the lid 20 are each opened by moving the handle 22 to the center of the device 10.
  • the handles 22 are each outside the lid 20 and arranged on the side of the lid 20, which abuts with the cover frame 12 closing.
  • opening a lid 20 of this cover 20 is pushed over the closed at this time, each other cover 20 by means of a guide located in the cover 12 partially overlapping.
  • FIG. 2 is in a detail view the top, in Fig. 1 shown left edge of the cover 12 of the refrigerator and / or freezer 10 according to the invention shown. Also in Fig. 2 shown is the left cover 20, which has a glass pane 24 to allow 10 view of the interior 14 even when the refrigerator and / or freezer is closed. Out Fig. 2 can also be seen how the cover 20, shown here slightly open, even at a slight opening rises obliquely upward from the cover frame 12 to be pushed over the not shown here right cover 20 overlapping over.
  • Fig. 3 shows an outbreak representation of the left, rear upper corner of the refrigerator and / or freezer 10 according to the invention, wherein for better inspection, a part of the cover frame 12 has been cut out graphically.
  • a damping element 30 is disposed in a recess, which is designed in a preferred embodiment as a combined oil gas spring. It is equally conceivable that the damping element 30 is an oil damper or a gas pressure damper.
  • the damping element 30 is a damping cylinder which has return means designed as a gas spring, by means of which the damping element 30 can be returned to the starting position of the damping element.
  • the damping element 30 can be used immediately.
  • the initial position of the damping element 30 is defined by the extended damping cylinder of the damping element 30, the length of the damped closing path of the cover 20, which is designed such that the closing distance are in any case greater than the size of a child's hand.
  • Fig. 4 shows the same view as Fig. 3 but with the lid 20 slightly open, wherein the damping element 30 has already been moved into the starting position by means of its restoring means, not shown.
  • the damping cylinder of the damping element 30 strikes against the inner edge of the cover frame 12 and attenuates by the retraction into the damping piston of the damping element 30, the closing movement of the closing cover 20th
  • damping elements 30 are arranged symmetrically on the outside of the cover 20 or on the side of the cover 20, which abuts closing on the cover frame 12 during the closing process.
  • a damping element 30 is located longitudinally below the frame 24 carrying the disc of the cover 20 is in a recess to act during the closing operation damping against movement on the cover frame 12.
