DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS
(24) The cabinet 2 as illustrated is provided for a laundry appliance, in this example a laundry washing machine, and comprises a housing 10, a front panel (or front wall) 12 and a bracket element (or: bridging element, transversal element or bar) 14.
(25) The housing 10 includes two vertical side walls 10A, 10B, a vertical rear wall 10C and a bottom part 10D. For example, the side walls 10A and 10B, the rear wall 10C and the bottom part 10D of the housing 10 are connected to each other by screws or other fastening elements.
(26) The bracket element 14 connects both side walls 10A and 10B in an upper front region in a transversal horizontal direction thereby providing for and increasing the stiffness of the cabinet 2 in the front.
(27) In the embodiments of
(28) For example, the bracket element 14 has an elongated, preferably substantially flat, form of a bracket or a bar or sheet or the like with two relatively short end portions 36A and 36B which are connected with the relative long horizontal middle part (or: central portion) 36D through a relatively short step-like or bent or S- shaped intermediate or transition portion and are basically parallel to the middle part 36D and, in the mounted state, displaced downwards with respect to the middle part 36D.
(29) Preferably, the bracket element 14 is made of a metal sheet, for example with extruding portions produced by stamping, punching and/or bending. In this example, said metal sheet has a thickness of about 0.6 to 1.5 mm, for example 1.2 mm in case of a separate bracket element 14 and 0.7 mm in case of an integral bracket element 14. Also the side walls 10A and 10B and/or the front panel 12 are preferably made of metal sheet, but can also be made of a plastics material.
(30) The end portion 36A of the bracket element 14 is connected from above to a corresponding connecting portion 136A positioned on a connection bar (or: connection flange, connection bend) 101A at the inner side of the side wall 10A, i.e. the side facing the other side wall 10B, whereas the other end portion 36A of the bracket element 14 is connected from above to a corresponding connecting portion 136B positioned on a connection bar 101B at the inner side of the side wall 10B, i.e. the side facing the other side wall 10A.
(31) Each connection bar 101A and 101B at each side wall 10A and 10B has an upper substantially flat and horizontal surface as a resting (or: bearing) surface for at least a part of the corresponding end portion 36A or 36B of the bracket element 14 and at least two screw holes 22 and 26, matching in the mounted state with a respective screw hole 31 and 33 in the end portion 36A or 36B of the bracket element 14 to insert and rotate a fixing screw 38 from above vertically in each pair of overlapping or matching screw holes 22 and 31 and 26 and 33 as parts of the connecting portion 136A or 136B. Preferably also a third screw hole 24 and/or a slot 28 (to be explained later) are provided in each connecting portion 136A or 136B (see
(32) Each connection bar 101A and 101B or its resting surface 102A and 102B is displaced downward or placed deeper than the upper edge 100A and 100B of the side wall 10A and 10B by a vertical distance or depth t (see
(33) The front panel (or: front wall) 12 covers, for example as seen from the front in a horizontal projection, completely the front side of the housing 10 and for example the front faces (or: front sides) 112A and 112B of the two side walls 10A and 10B. The front panel 12 for example at least abuts with or extends further outwardly than the housing 10 or the side walls 10A and 10B in lateral and vertical directions.
(34) Preferably the front panel 12, in the mounted state as shown in
(35) In the front panel 12 a drawer opening 121 for arranging a drawer 221 for detergents etc. (
(36) In the embodiments shown in
(37) In
(38) In the embodiments of
(39) As can be seen best in
(40) The bracket element 14 is placed, with its respective end portions 36A and 36B on top of the connecting flaps 12A and 12B in its front portion and directly onto the resting surface 102A and 102B in a subsequent further backward portion in such a way or until the screw hole 31 of the bracket element 14 overlaps with the screw hole 18 of the connecting flap 12B (or: 12A) underneath and with the screw hole 22 of the connecting portion 136B (or 136A) yet further underneath and the screw hole 33 of the bracket element 14 overlaps with the screw hole 26 of the connecting portion 136B (or 136A) underneath. In this way there is, as can be seen best in
(41) In order to provide for intermediate space for the connecting flap 12A or 12B in between the end portion 36A or 36B of the bracket element 14 and the connection bar 101A or 101B of the side wall 10A or 10B and, at the same time, to allow for direct contact behind the connecting flap 12A or 12B there is a transition or step 35 in the lower surface of the end portion 36A or 36B compensating for the different heights required.
(42) Further, the bracket element 14 includes a protruding hook 32 at each front portion, for example in the end portions 36A or 36B or intermediate portions towards the middle part 36C, for prepositioning the bracket element 14 and the front panel 12 with each other by hooking the hooks 32 into corresponding receiving sections, for example flanges or openings, at the rear side or inner wall of the front panel 12.
(43) Also the front panel 12, at its inner wall 12D and between the connecting flaps 12A and 12B is provided with a horizontal connecting flange 12C which is supported by a supporting surface 36C of the middle part 36D of the bracket element 14. Preferably, the flange 12C has several e.g. three, screw holes 125 matching with screw holes 145 in the supporting surface 36C for additional fixing by screws (not shown).
(44) In the embodiments according to
(45) As illustrated in
(46) A second fixing screw (not shown) can be screwed or inserted and rotated through the two overlapping screw holes 33 and 26 to directly fix the bracket element 14 to the side walls 12A and 12B to provide for a four point connection with higher rigidity.
(47) The screws, for example screws 38, can be self-cutting, i.e. their thread portions 38B cut their own counter-threads into a collar provided around the screw hole 22.
(48) Instead of screws other fastening elements can be provided, which for example provide for a fixing movement in the vertical fixing direction FD, for instance rivets or snapping elements, as long as they provide for a sufficient fixing force.
(49) As the fixing direction FD is vertical and from above, for example along the direction of gravity, against a horizontal counter or resting surface, the connection is very stable at the fixing points and easy to assemble, as the weight of the front panel 12 is carried and as enough space during the assembly is provided for the fixing operation even in this case of a high front panel 12 jutting out at the top. Furthermore the screws or other fastening elements can be elegantly hidden from sight.
(50) However, due to the vertical fixing direction FD the fixing movement itself cannot provide for a horizontal pulling force for pulling the front panel 12 towards the housing 10, for example against the front faces 112A and 112B, in order to avoid gaps due to tolerances and disturbing rattling noises as a result of that.
(51) Therefore, in addition, a pulling or positioning device is provided for exerting a pulling force F pulling the front panel 12 towards the housing 10, for example towards or against the front faces 112A and 112B of the side walls 10A and 10B.
(52) If there is, as shown e.g. in
(53) A preferred embodiment of such pulling or positioning device is illustrated in
(54) The longitudinal axes of the pulling slots 20 and 28 and the pulling flaps 30 each extend, preferably in all embodiments, horizontally and perpendicular to a front plane of the front panel 12 and/or parallel to the side walls 10A and 10B and their upper edges 100A and 100B or wall planes and/or along the longitudinal directions of the horizontal bars 101A and 101B in order to allow for a pulling action in that direction, which corresponds to the pulling direction PD. A rear inner wall of each slot 20 in the inward direction or pulling direction PD is designated by 200.
(55) Now each pulling flap 30 protruding downwards from each horizontal end portion 36 of the bracket element 14 is flat and slightly thinner than the slots 20 and 28 so that it can be inserted into the slots 20 and 28. Furthermore, each pulling flap 30 has a vertical front edge 301 and a vertical rear edge 302 which is shorter than the front edge 301 and ends in a convexly curved guiding or sliding edge 300, e.g. a rounded corner. The front edge 301 preferably ends in a rounded positioning aid edge 303 being the furthest downward part of the flap 30. The guiding or sliding edge 300 preferably is connected with the positioning aid edge 303 by a straight horizontal edge.
(56) During assembly the pulling flap 30 enters first with its positioning aid edge 303 the two slots 28 and 20 and then the sliding edge 300 comes into contact with the upper surface of the connecting flap 12B next to the rear inner wall 200 of the slot 20. The distance between the rear edge 302 of the flap 30 and the rear inner wall 200 of the slot 20 is designated by d2 and is preferably greater than the distance d1, i.e. d2>d1 (
(57) The screw 38 being screwed in the fixing direction FD exerts a vertical fixing force downward in the fixing direction FD onto the end portion 36A or 36B of the bracket element 14 which, conducted or transferred through the bottom wall 131, presses or forces the pulling flap 30 further into the pulling slot 20 wherein the curved guiding or sliding edge 300 rolls or slides over the upper edge of the rear inner wall 200 and the flap 30 glides or slides or moves into the slot 20 so that the rear edge 302 of the flap 30 eventually rests against the rear inner wall 200 at the inside of the slot 20 (
(58) This results in a pulling movement in the pulling direction PD of the connecting flap 12A or 12B with respect to the pulling flap 30 and thus the connecting flap 12A or 12B exerts a pulling force F onto the front panel 12 which first closes the gap of the distance d1 to the side wall 10A or 10B or its front face 112A or 112B and then results in a residual pulling force F which is a result of elastic deformation within the connecting flap 12A or 12B and the front panel 12 by the distance d2d1. The residual or remaining pulling force F or pressure of the front panel 12 against the housing 10, e.g. the front faces 112A and 112B, reduces the problem of rattling significantly. The screw hole 18 in the connecting flap 12A or 12B is big enough to allow the latter to be moved relative to the screw 38 by the distance d2 in the pulling direction PD.
(59) The screw 38 is then screwed or turned further into the screw hole 22 to finish its fixing movement in the fixing direction FD until, in a final fixing position of the screw 38, the end portion 36A or 36B is in contact and pressed onto the connecting flap 12A or 12B and the connecting flap 12A or 12B onto the resting surface 102A or 102 (
(60) The flap 30 and the slot 20 constitute examples for pulling elements of the pulling device. In an embodiment not shown, the flap 30 and slots 20 and 28 can also be arranged in reverse order or exchanged at the parts. Also pulling elements with bigger and/or more complex sliding and resting surfaces than just edges 300 and 302 etc. can be provided. Other pulling elements for transforming the vertical fixing movement into a horizontal pulling force or also movement are possible, such as a gear, for example toothed gear.
