Definitions

  • the present invention relates to a locking mechanism used for household appliances, particularly for refrigerators.
  • the locking mechanisms of the household appliances do not function property due to various reasons such as the differences in measurements that may occur during the manufacturing and assembly stages of the cabin and its4oor, or due to the effect of the working environment on the mechanism. Furthermore, a movable handle to be attached to said mechanism is required for the opening/closing of these mechanisms. Additionally, as these locking mechanisms consist of numerous parts, their production and service are quite difficult.
  • a latch on the door passes through a "U" shaped clips protruding outwards from the cabin frame, in order to close the door.
  • Said locking mechanism is controlled by means of a handle.
  • French Patent No. 2367176 a locking mechanism based on the fact that a latch on the door engages to another latch provided on the cabin frame* is described. In this mechanism a sufficient volume for the lateral extension of the latch and additional parts for transferring the movement of the handle to the latch are required.
  • the French Patent No. 2538517 describes a locking mechanism for the freezer compartment, where a latch moved by a handle engages to a datch provided on the frame.
  • the object of the present invention is to realize a locking mechanism comprising a small number of parts, thus occupying less space, which is simple and easy to produce, to mount and to perform the service-after-production, and which does not have to be controlled by an additional part such as a handle, that provides the opening/closing of the door easily without being effected by the differences in measurements that may occur during the manufacturing and assembly stages of the cabin and its door and by the working environment.
  • Figure 1 is the perspective view of a household appliance with a locking mechanism.
  • Figure 2 is the exploded view of the locking mechanism.
  • Figure 3 is the three dimensional view of the latch.
  • Figure 4 is the-dimensional view of the locking protrusion

  • Figure 5b is the perspective view of the latch recess
  • Figure 6 is the profile view of the locking protrusion placed on the cabin
  • Figure 7a is the schematic view of the latch and the locking protrusion before locking is started
  • Figure 7b is the schematic view showing the movement just before locking, when the latch is engaged to the locking protrusion and is brought to a jump-over point.
  • Figure 7c is the schematic view showing the latch when it is released from the locking protrusion and brought to a locking position.
  • Figure 8 is the perspective view of a household appHance with an alternative embodiment of the locking mechanism according to the present invention.
  • Figure 9a is the schematic view of an alternative embodiment of the locking mechanism according to the present inventi n showing the latch and the locking protrusion before locking is started.

  • Figure 9c is the schematic view of an alternative embodiment of the locking mechanism according to the present invention, showing the latch when it is released from the locking protrusion and entered to a locking position.
  • Figure 10 is the perspective view of an alternative embodiment of the locking mechamsm according to the present invention.
  • the household appliances, preferably refrigerators comprise a cabin (I) constituting the device; a door (2) to provide the use of the inner cabin (1) by the user; one or more compartments (3) for the most efficient use of the inner cabin (1) volu ⁇ ie; and an inner door (4) for opening/closing pf the said compartment (3) according to using purposes. Opening/closing of the door (2) and/or inner door (4) is provided by a locking mechanism (6).
  • said locking mechanism. (6) is only used for the opening closing of the inner door (4).
  • One or more fixed handles (5) are provided on the inner door (4), which are independent of the locking mechanism and which are used by the user by being pulled or pushed for opening or closing the inner door (4).
  • Said locking mechanism (6) comprises a latch-recess (8) placed on the inner door (4), a locking protrusion (12) fixed on the cabin (1) so that it faces the latch-recess (8) and a latch (7) made of elastic material, linear or purvilmear, preferably in a "S" form functioning as a spring, placed in the latch-recess (8).
  • Said latch-recess (8) is provided with a clasping recess (13) to attach the latch (7).
  • the latch (7) is provided, at one end, with a clasping protrusion (14) placed in the clasping recess (13) and with a locking catch (10) that provides opening/closing by moving on the locking protrusion (12); and comprises one or more twists (9) preferably in "S" shape, that provide the operation of the locking mechanism (6) by functioning as a spring between the said latch (10) and the clasping protrusion (14) due to their resilient structure; and a locking extension (11) with such a length that when it is placed in the latch recess (8) it remains outside said recess (8) and when the inner do ⁇ r (4) is closed, it comes over the locking protrusion (12), so tat it enables the locking catch (10) to move over the locking protrusion (12) while closing the inner door (4) by leaving it outside the latch recess (8).
  • the locking catch (10) is in the form of a triangularprism. While engaging the latch (7) to the latch-recess (8), the clasping protrusion (14) fits into the clasping recess (13), latch (7) being pushed from the locking catch (10) towards the clasping protrusion (14), is compressed due to its twists (9) and thus its dimensions are minimized so that it is pushed and fitted into the lateh- recess (8) and is released after being fitted into its recess (8) so that its escape from the latch-recess ⁇ 8) is prevented due to its released and thus extended twists (9).
  • the locking catch (10) starts to advance towards the jump over point on the curvilinear rear surface of the locking protrusion (12).
  • the locking protrusion (12) pushes the catch (tO) upwards until it reaches said jump-over point and thus compresses the latch (7).
  • the locking catch (10) thatpassed over the jump-over point slips over the locking protrusion (12) as the compressed latch (7) pushes it, and is released from the locking protrusion (12); thus the inner door (4) is opened.
  • the latch (7) is fitted into a latch-recess (8) formed on the cabin, and a locking protrusion (12) formed on the inner door (4) as opposing the latch recess (8) is fixed:
  • a latch-recess (8) is not used, a flexible, linear latch (7) having spring properties, preferably in a "L" form, one end of which is attached and the other end being free, and opposing said latch (7) a locking protrusion (12) that provides the opening/closing by passing from oiie side of the latch (7) to the other side is used.
  • the locking mechanism (6) locks the inner door (4) to the cabin (1) properly without being effected by the measurement differences that may originate due to production and/or assembly faults.
  • the locking mechanism (6) operating independently of the handle (5) can easily open or close when the door (4) is actuated and meanwhile the application of undesired forces on the inner door (4) and body is avoided. Furthermore, said locking mechanism (6) occupies a small space in the inner volume of the device. With this invention, a simple locking mechanism (6) with a small number of components, which is easy to produce, to assemble and perform the service procedure, has been realized.
