Definitions

• the present invention relates to a refrigerator, comprising a body which defines an interior space, a door, on the inner side facing the inside latching means are arranged, a door rack with counter-latching means, a Raststoffan extract in a corresponding formation of latching means and counter-latching means for stepwise height adjustment of the door compartment in several Detent positions, as well as an unlocking means for releasing a current detent position of the door compartment.
• a generic refrigerator is described in DE 85 17 976 U1.
• the refrigerator door described therein has on the inside of height-adjustable arranged storage container, which are arranged removably between protruding from the inside of the door vertical bars on rack-like notches.
• the in their rear area with laterally projecting claws hooked into a groove in the flanks of the spars storage container can be adjusted in height according to stepwise on its rear side locking lugs of the pitch of the notches.
• the refrigerator door should be easy to produce on the one hand and on the other hand, a slight adjustment of the altitude of the storage container arranged on its inside are possible.
• the resilient arms are formed in DE 92 04 742 U1, which are latched into recesses and must be solved by means of a button.
• resilient or spring-mounted arms are mounted on the side parts of the Abstell anyer, which are provided with latchable in locking recesses or latched on knob-like elevations counter-locking parts.
• the refrigerator door is provided with recesses or elevations on which can then snap at any height, the side parts of the storage container. By pressing the buttons they can be disengaged from the current position and locked at desired locations other height.
• the disadvantage here is that even with unactuated buttons the resilient Arms can slide out of the recesses when a high load force acts on the counter-locking parts.
• the object of the invention is to provide a refrigeration device, in which a height adjustment of the door compartment is reliably prevented when the unlocking means unactuated.
• the door racks can interlock with latching strips of the refrigerator door, with locking means being provided which hold the door racks in the current position on the latching strip.
• the locking means according to the invention or also referred to as unlocking serve to lock the counter-locking means in their locking positions, so that the counter-locking means can not slip out of the locking means even at high forces acting on them. This is particularly important if the contours of locking means and counter-locking means are designed such that no self-locking can occur.
• a bolt which can be set in the displacement of the counter-latching means, or the Rasnase, so that the counter-locking means, or the Rasnase can not be undesirably pushed out of the latching means or the latching niche.
• the bolt is in un-engaged unlocking in its locked position, i. only when the door racks to be adjusted intentionally, the actuating means of the unlocking means are to be pressed, so that the latch release the adjustment of the counter-locking means, or the Rasnasen and the door racks can be moved.
• the counter-locking means therefore has a bolt which, when the unlocking means are not actuated, can be moved between a locked position and a release position. Position lying adjustment of the counter-locking means is set and prevents movement of the locking lug out of the detent niche out.
• the counter-locking means according to the invention can be integrally formed and stored in a housing.
• This separate housing of the counter-locking means may have a first opening through which protrudes the locking lug and having a second opening, in particular a lower second opening through which an actuating means of the unlocking means protrudes.
• the actuating means forms a control button for releasing the locking latch.
• the locking lug remains in the locked position due to a resilient bias, i.
• the Rasnase initially remains in the detention niche. By moving up or down the door compartment, a force is generated which pushes the lawn nose out of the latching niche. Due to an example. Arc-shaped or wedge-shaped contour, the Rasnase is pushed out of the detent niche when it slides along a latching web between two rhinos along. When you skip a locking bar is generated by re-snapping the locking lug in the new detent niche due to the elastic bias a clearly audible clicking sound. This clacking sound gives the user an acoustic indication of the adjustment movement of the door compartment that has taken place and the renewed secure locking of the locking means arrangement. By the pressed back into the housing locking lug the locking means assembly is released for a short time and the door rack can be optionally offset one step down or up.
• the actuating means pivots out of the housing by means of spring bias only again when the latch is back in the locked position.
• the release position of the locking lug is a shaft which is connected to the locking lug against pivoting back of the bolt in the adjustment of the counter-locking means.
• the bolt may be provided on a lifting lever-shaped unlocking means, which is mounted by pressing an actuating means or the control knob from a locking position in a release position pivotally mounted on the counter-locking means.
• the unlocking means may be pivotally mounted in the housing.
• the actuating means has the control knob.
• the control knob may be integrally formed with the lever. The lever acts upon actuation of the control knob, so that the latch can be pressed out of the latching niche of the latching means and into the housing.
• the latching niches can be provided on a latching means arrangement which has at least one strip-like latching means with a plurality of latching niches arranged one above the other.
• Each counter-locking means may be formed in a housing, which may be attached, for example, by means of a Schnapprastitati on the door racks. It may be a releasable snap connection.
• two counter-locking means are provided at each door rack. And on two opposite sides of the door compartment, preferably mounted on a rear side of the door compartment. Due to the separate design of the counter-locking means in a housing identical and thus variant-reduced counter-locking means can be used for a variety of differently designed door racks. It can be used on the same refrigeration device also different door racks, since the locking means assembly is always identical.
• the counter-locking means may comprise a base plate with a stub axle, on which the lifting device is pivotally mounted.
• the base plate can be a part of the housing, for example, the base plate can be formed by a rear wall of the housing.
• the unlocking means may be formed as a two-armed lever.
• the unlocking means may comprise a first lever arm having a lever length different from a second lever arm.
• the shorter lever arm can form the bolt.
• the longer lever arm can be limited in its mobility at least on one side by a stop, in particular by a web and / or a rib.
• the locking lug can be mounted displaceably spring biased in a linearly movable guide in the locking position.
• the guide can be provided on the base plate or on the housing. Preferably, the guide is formed integrally with the base plate.
• a loop-shaped spring portion may be provided, which is connected to the pivotable unlocking means.
• the loop-shaped spring portion causes a resilient bias of the unlocking in its locking position and at the same time a resilient bias of the latch in its locked position.
• the loop-shaped spring portion may be supported for generating a spring bias in the locking position both for the pivotable unlocking means, as well as the displaceably mounted locking lug on an abutment of the base plate.
• the abutment can be formed by a side wall of the base plate.
• the loop-shaped spring portion may have an extension, by which the spring portion is supported on a side wall of the base plate.
• the detent may be formed together with the unlocking and the loop-shaped spring portion as a one-piece component. Due to the loop-shaped spring section, which connects the latching lug with the unlocking means and the latch, a number of components of reduced latching means arrangement is created.
• the latching lug may have a latching cam and a shaft and the shaft may be guided linearly on the baseplate both on two opposite first guide surfaces of the latching cam and on two opposite second guide surfaces of the shaft.
• the detent may have a spring portion for generating a biasing force.
• the latch should assume a basic position in which it engages in the latching niche and thus is in the locked position.
• the latching lug can be biased by the spring portion in the locking position. In this preloaded locking position of the spring portion is preferably at a stop of the base plate. This also ensures that after a release of the unlocking the counter-locking means always automatically moved back into the locking position.
• the spring portion may be formed by an elastic finger whose free end is, for example, supported on an inner wall or a projection of the housing.
• the shaft may be formed to form an end stop surface for the release position of the locking lug with a smaller width than the locking cam.
• the detent may be formed together with the unlocking means and the loop-shaped spring portion as a one-piece component, in particular as a plastic injection molded part.
• the forces occurring such as holding forces on the locking lug, actuating forces on the latching lug or spring clamping forces on the unlocking means can be transmitted reliably over the component.
• the base plate for limiting a maximum pivot angle for the unlocking means comprise a web.
• the web thereby limits the maximum bending that can occur on the spring section and thus causes a limitation of the internal stresses in the spring section.
• the spring section can not be bent beyond its load limit. This measure prevents unwanted violent breakage of Entriegelungsstoffs so that the life of the counter-locking means is guaranteed.
