OBJECT OF THE INVENTION.
[0001] As is expressed in the title of the present descriptive report, the following invention
consists of a device for the hinged fastening of household appliances doors, which
is preferably useful for its adaptation to automatic washing machines, allowing the
door assembly in a simple and fast way and giving at the same time an appropiate stability
to the door, avoiding some plays.
[0002] In this way, a considerable reduction of workforce is gotten because the assembly
of the turn spindle of the conventional washing machines doors is a laborious task,
being also its disassembly very laborious with the added drawback of the inappropiate
stability of the door once it is disassembled and it has been assembled again, while
both the assembly and the disassembly of the new device of hinged fastening can be
carried out in a simple and fast way since the assembly is carried out through the
simple clip and the disassembly acting on a spring.
[0003] Thus, the device is based on the assembly between the body of the apparatus door
and the front structure of the chassis that closes the door, so that it is formed
by a pair of projections that are inserted into the respective orifices of the apparatus
structure, being one of these projections moving.
FIELD OF APLICATION.
[0004] The device for the hinged fastening for a household appliance door is especially
applicable for its incorporation to an automatic washing machine, allowing the easy
and quick assembly and disassembly of the door with regard to its turn spindle.
BACKGROUND OF THE INVENTION.
[0005] In DE 40 40 291 A1 for the hinged fastening of the door of an automatic washing machine
there is a pair of L-shaped and at least nearly axial projections fastened with the
front chassis of the household appliance and provided with wing parts parallel to
the front chassis. The wings are provided with a pair of holes corresponding one to
another on the same axis and holding a pivotally shaft which is, on the other side,
fastened with a frame part of the door by an axle box and a fixing plate screwed to
the frame.
[0006] This embodiment is very laborious, not only because of the manipulation that must
be realized of all the components that form it, but also because its assembly is very
difficult in view of the workman cannot realize easily all the necessary manipulations
of the elements, having to invest a lot of time in the cited task with the economic
repercussion that it causes.
[0007] In the other hand, the disassembly of the door of the automatic washing machine is
very laborious too, and besides once it has been disassembled and assembled again,
the door often acquires a slight resistance that can cause it does not close properly.
DESCRIPTION OF THE INVENTION.
[0008] In the present report, a device for the hinged fastening system for a household appliance
door is described, which utility is for the preferred incorporation to automatic washing
machines. This household appliance comprises a body that is joined to the front chassis
of the household appliance and is formed by a frame like a circular crown with a U-shaped
general section with strengthenings. The frame contains a door glass so that the frame
surrounds a front loading opening of the front chassis and the glass covers it while
the door is closed.
[0009] Therefor two adjacent strengthenings are provided with respective holes which are
faced and aligned and one of said strengthenings is provided with a bevel over the
hole. This matter is proper for easily mounting the door to the hing, when the projections
of the door frame has a flexible positioned pivot shaft.
[0010] The door comprises a frame that is provided with a pair of L-shaped axial projections
whose wings are free to the external side and the axial projections have an addition
of thickness in their free extreme and in relationship to its external lateral side.
[0011] The axial projections comprises respective hinge projections for the arrangement
within the holes, so that one of that hinge projections is fixed while the opposite
hinge projection is mounted movable in a housing and is forced by a spring.
[0012] Thus, during the door assembly the fixed projection will be inserted into the corresponding
hole of one of the strengthenings with U-shaped outline of the frame on which is backed
the door frame in its closing, while the second moving projection will be inserted
into the hole of the opposite strengthening, making its assembly easy because of the
sliding of the upper bevel to the socket hole.
[0013] The disassembly of the door will be obtained in a simple and fast way, only acting
with a tool on the moving projection for the compression of the spring that affects
it, until it can be extracted from the hole where it is inserted so that the door
can be liberated.
[0014] In order to complement the description which is made hereinafter and for the purpose
of providing a better understanding of its characteristics, the present descriptive
report is accompanied by a set of drawings, in whose figures the most significant
details of the invention described in the present report are represented in an illustrative
an not limitative way.
BRIEF DESCRIPTIONS OF THE DESIGNS.
[0015] Figure 1.- It shows a detailed perspective view of the backing bodies with the closing
means, where we can observe the pair of projections that will act like turn spindles
of the household appliance door when they are inserted into the corresponding holes
of the pair of strengthenings of the frame with U-shaped outline that is interlocked
to the apparatus. We also can observe that the door frame has been represented in
relationship to the side of backing on the interlocked frame to the apparatus that
has been represented in a frontal way.
[0016] Figure 2.- It shows a detailed section view of the assembly way of the door in the
frame which is interlocked to the frontal chassis of the household appliance, where
we can observe how the fixed projection is inserted into its corresponding hole and
the moving projection also will be inserted into its corresponding hole so that the
cited fulfilment is favoured by its sliding through the upper bevel to the fitting
hole.
DESCRIPTION OF A PREFERRED EMBODIMENT.
[0017] In view of the above cited figures and in accordance with the used numbering, we
can observe how the device (1) for the hinged fastening of household appliances doors
(2) to the body (3) of the apparatus chassis is made up of the installation of a pair
of axial L-shaped projectings (9) in the frame (4) of the door (2) with their free
wing to the external part, which has an external adittion of thickness. These projectings
are placed in relationship to the U-shaped outline (5) that is joined to the apparatus
chassis in relationship to a pair of strengthenings (6) that are endowed of the respective
holes (7) where will be inserted the respective projections (10) and (11), which will
act as turn spindles.
[0018] For that, the L-shaped axial projectings (9) of the frame (4) of the door (2), have
respective projections (10) and (11) in relationship to their external side, so that
the projection (10) is fixed while the projection (11) is moving because it is placed
in a housing that is affected by the action of a spring (12). Logically, the trip
of the cited moving projection to the external part is limited, avoiding its flight.
[0019] On the contrary, the body (3) of the frontal apparatus chassis, that is backed to
the door (2) and doses it, is formed by a general U-shaped outline (5) which has a
whole of strengthenings (6) between its wings so that two of the contiguous strengthenings
(6) have respective aligned holes (7) with regard to their faced sides, so that one
of the strengthenings (6) has an upper bevel (8) on the corresponding hole (7).
[0020] Likewise, for making the coupling connection of both bodies easy, the contiguous
strengthenings (6) can show both bevels (8) placed on their corresponding holes (7)
so that thus the assembly is made easy because the projections, that act as a spindle,
can slide through the corresponding bevels (8).
[0021] In this way, during the assembly of the door (2), the axial projectings (9) stay
between the pair of strengthenings (6), being the fixed projection (10) inserted into
the corresponding hole (7) of one of the strengthenings (6), while the moving projection
(11) will be inserted into the hole (7) of the opposite strengthening (6) so that
the cited embodiment makes easy the bevel (8) on which the projection (11) can slide
until it is inserted into the hole (7).
[0022] Thus, the assembly of the door (2) is done in a simple way so the amount of labour
decreases substantially. Besides, its disassembly also is carried out in a simple
way because we only have to act on the moving projection (11), through a conventional
tool, in a easy way for moving it until it can be took apart of its placement and
to take out the fixed projection next so that the door remains dismounted in all.
[0023] Besides, at the moment in which the door has been dismounted and mounted again, it
remains with equal stability without adquiring the minimum play so that it has a bigger
useful life with perfect conditions of stability and watertighness.
