Definitions

  • the present invention relates to an appliance, whether or not a household appliance, equipped with an access door to the interior of the appliance, the hinge or pivot hinge of which is horizontal, that is to say of which the opening / closing direction is from top to bottom or, more rarely, from bottom to top.
  • the door of the device to be integrated is necessarily coated with a covering panel, which is made of wood, solid or not, or of another material, and the weight of which varies according to the nature of the material adopted for the covering as well as its thickness, for given overall dimensions; whereas, in cases 1) and 2), there is no requirement to dress the door.
  • a covering panel which is made of wood, solid or not, or of another material, and the weight of which varies according to the nature of the material adopted for the covering as well as its thickness, for given overall dimensions; whereas, in cases 1) and 2), there is no requirement to dress the door.
  • the solution adopted by the technicians in the matter for balancing the weight of the door of apparatuses of type 1) or 2), that is to say in free installation or built-in, is relatively simple, because the weight of the door is determined once and for all, due to the absence of dressing: in this case, a simple spring creating a return torque, relative to the pivot axis is sufficient, this spring being incorporated in the thickness of the door, which is produced in the form of a hollow panel, often metallic, and arranged at the two lateral ends of the door.
  • auxiliary return springs which, unlike the two springs main mentioned above, include a device for adjusting their tension to take account of the variable nature of the covering panel depending in particular on the nature of the material used for the panel and its thickness, with equal overall dimensions.
  • This adjustment device normally includes, at one of its ends, a screw (or threaded rod), which is accessible from the outside and the degree of penetration of which in a nut is adjustable, precisely by screwing, so as to vary the degree of tension of the corresponding auxiliary return spring, as a function of the effective weight of the dressed door.
  • This adjusting screw and the corresponding nut are arranged on the front face or on the top of the device and are covered by an appropriate cover making it possible to satisfy aesthetic requirements.
  • the object of the present invention is therefore to provide an apparatus equipped with a door with a horizontal pivot axis and with a device for balancing the weight of the door in a half-open position, in particular corresponding to a primer for opening the door, which meets the needs of the practice better than the apparatuses of the same type, and aiming at the same goal, previously known, in particular in that it makes it possible to modify a pose initially free or embedded in an integrated installation, or vice versa, either during the manufacturing or at the time of installation or at a later time of change of destination of the installation of the device, while allowing adaptation to the case of devices whose ribs are normally occupied by organs necessary for the operation of these devices.
  • the door is produced in the form of a hollow panel equipped with a removable access plate inside this panel, and in that the return and balancing spring of the door is arranged in the thickness of the hollow panel forming the aforementioned door.
  • the device for balancing the weight of the door comprises two return and balancing springs arranged in the thickness of the hollow door panel, each at a lateral end thereof, so as to avoid the twisting of the door which would result from an asymmetrical location of the balancing device with respect to a vertical plane of symmetry of the door.
  • the means for fixing the second end of the spring (s) consists of a bar, which is arranged, -as this (these) spring (s) -, in the thickness of the hollow panel forming the aforementioned door, parallel to this panel, and which is mounted, by its ends, in the lateral faces of the box of the apparatus.
  • the fixing bar is mounted in the lateral faces of the free box to rotate under the action of the pivoting of the door around its axis, that is to say of the energizing of the return and balancing spring (s) to avoid any risk of the spring (s) coming loose and, above all, generating an annoying noise during the door opening / closing.
  • the spring the return and balancing spring of the door cooperates with at least one second spring, a first end of which is fixed to the hollow panel forming the aforementioned door, whereas a second end is also fixed to the fixing bar of the second end of the first spring, the second spring being intended for balancing the weight of the hollow panel forming the aforementioned door, devoid of the panel full of cladding, while the first spring equipped with tension adjustment means is intended for balancing the additional weight of the covering panel.
  • the second spring and / or the first return and balancing spring are / is removable.
  • the means for adjusting the tension of the return spring (s) and adjustable balancing (s) comprises a threaded rod, a first end of this rod being fixed to a second end of this adjustable spring by means of a strap, while a second end of this threaded rod is intended to receive a nut for adjusting the tension of this (or these) adjustable spring (s) (s), after having passed a stop of this nut secured to the door.
  • the second the second end of the threaded rod and the nut for adjusting the tension of the adjustable spring (s) for return and balancing corresponding (s) are accessible outside on the front of the device, where they are covered by a cover.
  • the device 10 of the aforementioned variant for balancing the weight of the door 20 of an (electro) household appliance 100 such as an oven, a dishwasher or the like (of which only the portions useful for understanding of the present invention are shown), it comprises a first and a second main spring (not shown) intended to create, in a manner known to technicians in the field, a return torque of the door 20, relative to its axis of horizontal pivoting 21, when the door is ajar: in this case, each main spring (the ends of which are fixed to the axis of rotation and to the door) is dimensioned so as to balance the torque - in the opposite direction - than the weight of the door 20 without covering exerts around the axis 21 and which would tend to make this door fall heavily downwards, under the action of its own weight, with the risk of damage to the latter, if the main return springs were absent.
  • each main spring (the ends of which are fixed to the axis of rotation and to the door) is dimensioned so as to balance the torque - in the opposite
  • the balancing of the additional weight corresponding to the covering panel is ensured by the two auxiliary return springs 30, one end 32 of which is fixed to the axis of rotation 21, while the other end 31 is connecting, for each of them, to a device 50 for adjusting the degree of tension of the corresponding auxiliary return spring 30.
  • This device 50 comprises a threaded rod 52, one end 54 of which is fixed (by means of a part which will be described below) to the end 31 of the auxiliary spring 30, while the other end 56 of this rod 52 (accessible from outside the device 100, on the front face) is screwed into a nut 55, after having passed a stop 53 of this nut 55, which stop is integral with the door 20: the metering or adjustment of the screwing stroke of the rod 52 inside this nut 55 also makes it possible to balance the weight of the covering panel, which varies according to the nature of the material used for its manufacture, as well as the thickness adopted for the panel, for given dimensions of overall dimensions of the latter.
  • each auxiliary return spring 30 is arranged, at each lateral end of the door 20, so as to be contained in a plane parallel to the plane of the door. In practice, this is achieved by providing each auxiliary return spring 30 in the thickness of the hollow door panel (normally metallic: this door panel is of course, different from the trim panel itself) defining the actual door of the device.
  • This arrangement has the advantage of allowing the transformation, at any time, of a device previously laid freely or in a built-in manner into a fitting device which can be integrated by application to the door panel of a covering panel chosen according to the decor adopted for other integrable appliances and furniture, without having to dismantle the whole box (not shown), as it was necessary to do in the prior art, when the auxiliary return springs were arranged in a parallel plane ( see Figures 1 and 2) to the side panels 41 and 42 of the box.
  • the arrangement according to the present invention has the additional advantage of being able to be applied to devices, such as dishwashers, the sides of which are necessarily occupied by hydraulic organs (not shown) for adjusting the volume of dishwashing water.
  • Adjustment of the tension of each of the two auxiliary return springs 30 is facilitated by connecting the end 54 of the threaded rod 52, of the corresponding adjustment device 50, to the end 31 of the spring by means of a strap. 51 which is well suited to incorporating the device 50 into the door panel to be dressed.
  • FIGS. 3a and 3b this can also be read in FIGS. 3a and 3b, provided that the balancing device 10 is considered to have only two adjustable springs 30 (in principle, only one spring is sufficient, but reasons for actuation symmetry lead to adopt two to avoid, in particular the twisting thereof under the action of a single spring arranged asymmetrically with respect to a vertical plane of symmetry of the door), that is to say, provided that the adjustable springs 30 illustrated in FIGS.
  • the latter is advantageously produced in the form of a hollow panel (not shown) equipped with a removable plate, in particular on the front face.
