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 tum 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 of household appliances is especially appliicable for its incorporation into automatic washing machines, allowing the easy and fast assembly and disassembly of the door with regard to its tum spindle.
BACKGROUND OF THE INVENTION.
[0005] Conventionally, for the hinged fastening of the doors of automatic washing machines there are a pair of parallel pieces that are endowed of an angular reduce bigger than 180° in which a cylindrical stud, which will act as a tum spindle, will be lodged, so that the tubular body that is joined to the door and that is crossed by the spindle remains between the cited pair of pieces, for finally having respective strips that fix, in a gyratory way, the spindle with regard to the pieces where it is placed so that the cited strips stay fixed through some screws.
[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 accede easily to realize all the 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 of household appliances doors is described, which is preferably destined for its incorporation into automatic washing machines. This device is made up of the union of a pair of bodies that coincide with the frame like a circular crown of the closing door and with its backing frame on the front chassis of the apparatus in its closing, so that both bodies have the fastening means strickly speaking.
[0009] The interlocked body of the apparatus chassis on which the door frame is backed and closes it, is formed by a frame like circular crown and with U-shaped general section, which has a whole of strengthenings between its wings so that these stay frontally opened.
[0010] For the materialization of the gyratory fastening of the door, the fastening means of the frame that is joined to the apparatus chassis are defined by a pair of strengthenings that are placed between the wings with U-shaped outline so that the same have some respective faced aligned holes, so that one of the cited strengthenings presents a bevel on its corresponding hole.
[0011] The fastening means of the frame of the closing door are formed by a pair of axial L-shaped projections, with their free wing to the outside, whose extreme presents an adittion of thickness in relationship to whose extemal lateral sides present respective projections, being fixed one of the projection while the other extreme is moving because it is placed into a hole and affected by the action of a spring.
[0012] In the gyratory assembly of the apparatus door, the pair of axial L-shaped projectings of its door stay between the pair of strengthenings of the frame with U-shaped frame of the apparatus, staying the respective projections of the extemal sides of the axial L-shaped projectings of the door frame into the corresponding aligned holes of the pair of strengthenings belonging to the U-shaped outline that is joined to the front part of the apparatus.
[0013] 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.
[0014] 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.
[0015] 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.
[0016] 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.
[0017] 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.
[0018] 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 extemal 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 tum spindles.
[0019] 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 extemal 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.
[0020] On the contrary, the body (3) of the frontal apparatus chassis, that is backed to the door (2) and closes 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).
[0021] 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).
[0022] 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).
[0023] 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.
