Embodiment Construction

[0019] Such as figure 1 As shown, the hinge firstly comprises two fixing parts 1, 2, one of which is fixed on the door body (not shown). Such as figure 2 It can be clearly seen that the fixing parts 1 , 2 are drive-connected to each other via a lever. In the exemplary embodiment shown, the two articulation levers 4 , 5 are pivotably connected to the fastening part 1 by means of articulation points 7 , 8 at a distance from one another. At their free ends, the articulating levers 4 , 5 are connected by means of joints 9 , 10 to an articulated arm 3 , which is connected at their free ends by means of joints 11 , 12 to the fastening part 2 . The articulation lever 4 has an articulation point 21 in the central region, which is connected to an articulation lever 6 . At its free end, the articulated lever is rotatably connected to the fastening part 2 by means of a articulated joint 12 .

[0020] Depend on figure 2 It can be seen that the joint lever 5 is connected to a contro...

Abstract

Disclosed is a multilink hinge, especially for refrigerator doors, comprising articulated levers that are interconnected in a scissor-type manner. The parts (1, 2, 3, 4, 5, 6) forming the multilink hinge are covered by at least one lateral protective plate (15) as long as the same are in different positions relative to each other and form different intermediate spaces according to the open position of the hinge.

Description

technical field [0001] The invention relates to a multi-joint hinge, in particular to a multi-joint hinge for a freezer door, comprising joint levers connected to each other in a scissors manner. Background technique [0002] Many hinges of this type are known from the prior art, for example from patent GB 1066710 or US 5035026. [0003] These known hinges however have various disadvantages. [0004] Since very thick door bodies are used for thermal insulation especially in freezers, the hinges must have relatively long articulation levers in order to achieve the desired extension—away from the door body forward. As a result, gaps of different sizes are created between the articulation levers depending on the opening position, which gaps can increase or decrease during the door movement. There is a reduced risk of injury if, for example, a child inserts a finger into the gap. In this case, the scissor-like articulating lever acts like a cutting scissors. Contents of the...
