- The present invention relates to a laundry machine (1) such as a laundry washing or washing/drying machine comprising a water tub, a rotary drum, in which the laundry is to be placed and an electric motor rotating the drum. The laundry machine (1) has a front door (3) installed on a front wall (2) of the machine. The front wall (2) attached to a main body covered with an upper cover (5) comprises a control display (4) to enable programming of the laundry machine (1).
- The front door (3) of the laundry machine (1) comprising an inner lid (7), an outer lid (9) and an intermediary lid (8) attached thereinbetween provides access into the drum by way of operating a handle (16). The front door (3) is installed on the front wall (2) of the machine by a hinge portion (6) so as to ensure rotation of the front door (3) to effect locking and unlocking. The handle (16) on the other hand comprising external and interior handle portions (10, 11) operates so as to either release a locking mechanism or provides positioning of a respective hook (13) in the engaging state.
- The front door (3) opening mechanism typically functions in the manner that the handle (16) is operable to lock or unlock the front door (3). The mounting of the external handle portion (11) to the interior handle portion (10) is accomplished by way of coupling the two parts in the manner that a hook (13) rotating around a hook pin (15) in association with a hook spring (14) is operatively installable.
- The interior handle portion (10) connects to the intermediary lid (8) by means of several connection elements. The rotational movement of the interior handle portion (10) around a handle pin (12) passing through respective connection openings of the interior handle portion (10) attached to the intermediary lid (8) provides rotation of the handle (16) during opening and closing of the front door (3).
- The handle (16) effectuating opening and closing of the front door (3) is assembled by way of slidingly fitting tab connections between interior and external handle portions (10, 11) of the front door (3) as will be delineated below.
- The external handle portion (11) connects to the interior handle portion (10) that is in mechanical communication with the intermediary lid (8) through respective connection elements. The external handle portion (11) comprises a two-staged structure, namely a first level (33) and a second level (34), the latter forming a raised surface portion with respect to the first level (33). The components positioned on both levels of the external handle portion (11) engage with the corresponding stages of the interior handle portion (10) also having respective first level and second levels (33, 34), thereby ensuring a rigid assembly of the handle (16).
- A pair of alignment units (25) of the external handle portion (11) situated as rectangular blocks with open-sided divisions forming consecutive U-form structures communicates with the first and second level (33, 34). The alignment units (25) assist in centering of the external handle portion (11) to provide engagement with the corresponding connection elements of the interior handle portion (10).
- The alignment units (25) slide relative to a pair of guideway portions (28) of the interior handle portion (10) cooperatively aligning the two parts, while a plurality of resting portions (26) of the external handle portion (11) in the form of raised linear elements fit to the interior handle portion (10). The divisions of the alignment units (25) correspond to the structural level differences of the guideway portion (28) to provide a reciprocally interconnected network of elements allowing linear movement of the external handle portion (11) relative to the interior handle portion (10).
- Resting portions (26) are formed as linearly extending raised surface elements in parallel with the guideway portion (28) at the first level (33) of the interior handle portion (10). Additional resting portions (26) between two latching members (23) as well as those between the alignment units enables accurate alignment of the two handle parts relative to each other during the mounting of the external handle portion (11) such that all other parts sequentially engage with each other by the advancement of the external handle portion (11) in the radial direction of the front door (3) towards the interior handle portion's (10) linear edge.
- By the advancement of the external handle portion (11), a linear engagement portion (21) thereof slides into a fastener strip (22) of the interior handle portion (10), the engagement portion (21) being arranged adjacent to the linear edge of the interior handle portion (10). The engagement portion (21) is a raised longitudinal L-cross-section extension proximate the linear edge of the first level (33) extending perpendicular to the alignment units (25). The engagement portion (21) is structured to fit into the interior handle portion's (10) fastener strip (22) in a continuous manner.
- A pair of latching members (23) is situated on the center of the second level (34) of the external handle portion (11) proximate the semi-circular edge thereof and neighboring the resting portions (26). The L-cross-section structures of the latching members (23) engage with latching enclosures (24) of the interior handle portion (10) providing fixation of the external handle portion (11) during the advancement thereof in a mounting direction (35) perpendicular to the engagement portion (21) or the fastener strip (22).
- The latching enclosures (24) are also L-shaped structures positioned adjacently to the guideway portions (28) in the form of an open-sided structure engagingly enclosing a latching member (23) therein. The L-cross-section forms of the latching member (23) and the latching enclosures (24) extend perpendicular to each other so that mating of the two parts ensures a fixed multi-axis engagement on the vertical axis as well as in the mounting direction (35), i.e. while the external handle portion (11) is slidably mounted with its linear edge being moved towards the linear edge of the interior handle portion (10).
- Further, a pair of fixation tabs (19) laterally situated on the inner face of the first level (33) of the external handle portion (11) engages with a fixation portion (18) of the interior handle portion (10). The fixation portion (18) of the interior handle portion (10) having a pair of vertical side-walls having inclined upper edges with respect to the surface of the interior handle portion (10) engages with a respective fixation tab (19) in the manner that the fixation tab (19) in the form of a vertical wall extending perpendicular to the mounting direction (35) is slid over the side-walls having inclined upper edges. When the fixation tab (19) is slid over the side-walls of the fixation portion (18), it rests on a release ridge (17) positioned adjacent to a receiving section (20) in the form of a cavity suitable for detaching the fixation tab (19) from the fixation portion (18) by way of using a suitable object such as screwdriver tip.
- The fixation tabs (19) are in the form of U-shaped structures having shorter arm portions and a larger base portion of the U-form being positioned in a way that the cavity of the U-form faces towards the engagement portion (21). Therefore an operator can use a suitable tool to force an engaged fixation tab (19) upwardly thanks to the arm portions of the U-form. The connection of the fixation tabs (19) with the fixation portions (18) provides a fixedly assembled structure on the mounting axis in both directions.

- In a further embodiment of the invention, a linear engagement portion (21) of the external handle portion (11) extending perpendicular to the mounting direction (35) is slidably engaged with a fastener strip (22) of the interior handle portion (10), the engagement portion (21) being arranged adjacent to a first edge of the interior handle portion (10).
- In a further embodiment of the invention, the engagement portion (21) is a raised longitudinal L-cross-section extension structured to fit into the interior handle portion's (10) fastener strip (22) in a continuous manner.
- In a further embodiment of the invention, the latching members (23) are situated on the second level (34) of the external handle portion (11) proximate a second edge thereof.
- In a further embodiment of the invention, the latching enclosures (24) are L-cross-section structures in the form of an open-sided structure engagingly enclosing a latching member (23) therein.
- In a further embodiment of the invention, the latching members (23) and the latching enclosures (24) have L-cross-section structures and the L-cross-section forms of the latching member (23) and the latching enclosure (24) extend perpendicular to each other.
- In a further embodiment of the invention, a pair of fixation tabs (19) situated on the inner face of the external handle portion (11) engages with fixation portions (18) of the interior handle portion (10), the fixation portions (18) having a pair of vertical side-walls having inclined upper edges with respect to the surface of the interior handle portion (10).
- In a further embodiment of the invention, the fixation tab (19) in the form of a vertical wall extending perpendicular to the mounting direction (35) is slid over the side-walls having inclined upper edges such that when the fixation tab (19) is slid over the side-walls of the fixation portion (18), it rests on a release ridge (17) positioned adjacent to a receiving section (20) in the form of a cavity.
- In a further embodiment of the invention, the fixation tabs (19) are in the form of U-shaped structures having shorter arm portions and a larger base portion of the U-form being positioned in a way that the cavity of the U-form faces towards the first edge.
- In a further embodiment of the invention, a pair of attachment housings (31) in the form of L-cross-section surface projections situated at the second level (34) of the external handle portion (11) laterally provides additional connection lines so as to cooperate with attachment portions (32) defined as corner portion structures of the interior handle portion (10) on the opposite edge corners of the fastener strip (22).
- The present invention therefore provides a handle structure allowing easy mounting and detaching so that rework operations may be performed advantageously quickly. Furthermore, once mounted, the components will not be subject to deformation over time or lose their fixation axes.
