- the first pin member 30 is fixed to the internal surface 13c of the furniture door 13 by means of a fixing plate 28 (see figures 4 , 5 and 6 ) and extends from the surface 13c towards the recess 18 of the refrigerator door 5; during doors rotation, the first pin member 30 is designed to slide horizontally through an elongated slot 24 of wall 20 to which it is slidingly coupled by means of a wheel 29.

- the soft/self closing device 17 operates as follows.
- the slide 22 When the doors 5, 13 are closed, the slide 22 is in the first stop position and in the engagement condition ( figures 7a-7c ), wherein it is coupled with the first pin member 30. In this condition, the spring 23 is not tensioned (or slightly tensioned) and the damper 25 is ineffective.
- the linear displacement of one door with respect to the other causes the sliding movement of the first pin member 30 in the slot 24 and, as the pin member 30 mates with the engagement portion 32a of slide 22, a corresponding dragging movement of slide 22 along the guide 21.
- the slide 22 slides horizontally, as the second pin member 33 and the protruding members 32b both engage the first portion 21a of slide 21,
- the soft/self closing device 17 works in the first operating mode, wherein the damper 25 and the spring 23 are active between the first and the second door 5,13.
- a connection chain between furniture door 13 and refrigerator door 5 is in fact established through pin member 30 carried by furniture door 13, slide 22 mated with pin member 30, damper 25 and spring 23 both connected with slide 22, and elongated body 19 carried by refrigerator door 5.
- the soft/self closing device 17 keeps working in the first operating mode.
- the spring 23 pulls back the slide 22 towards the first stop position, and the slide 22 drags the first pin member 30 in this movement. Accordingly, the doors 5, 13 are forced back to the closed position.
- the damper 25 applies its damping action on the slide 22 thanks to the force applied by the shaft 27 on the push member 31. Therefore, the combined action of the spring 23 and damper 25 accomplishes a self and soft closing action.
- the damping action is applied also if the user, instead of leaving the doors 5, 13 free to move, pushes the doors 5, 13 to close them. In this case, the pushing action of the user simply adds to the self closing action performed by the spring 23.
- the above effect is avoided thanks to the mechanism that switches, during door opening, the soft/self closing device 17 from the first operating mode to the second operating mode when the limit value of the opening angle ⁇ is reached.
- this switching mechanism deactivates the spring 23, so that in the second operating mode not only a further rotation of the doors 5, 13 (and thus a further displacement of one door with respect to the other) cannot cause further tensioning of the spring 23, but also the spring 23 has no more action on the furniture doors 13.
- the damper 25 is no more operative_ as from the above limit value of opening angle ⁇ , since in the second operating condition of the soft/self closing device 17 the slide 22 is disengaged from the first pin member 30 and rests in the second stop position.
- the above disclosed connection chain between the two doors is interrupted by the disengagement of the pin 30 from the slide 22.
- the engagement member 32 rotates (counter-clockwise in the representation of figure 8a ) and the two protruding members 32b move into the second portion 21b of guide 21, where they abut against the wall 21c.
- the soft/self closing device 17 is in the second operating condition, wherein the first pin member 30 is disengaged from slide 22 and can then move freely (direction B in figure 6 during door opening) along slot 24 ( figure 6 , figures 9a-9c ).
- the doors 5, 13 can freely move without any elastic pulling-back action or damping action.
- the soft/self closing device 17 works in the second operating mode, in which both the spring 23 and the damper 25 are inactive, until the limit value is reached. Then, the soft/self closing device 17 switches back from the second operating mode to the first operating mode, by the re-activation of the spring 23 and the damper 25. Accordingly, the spring 23 restarts applying a force on the doors 5, 13 tending to close them, and the damper 25 restarts applying a damping effect to smooth door closing. In other words, door closing with soft/self closing effect is performed as above outlined.
- the first pin member 30 initially moves freely along slot 24, and no self/soft closing action is applied to the doors 5,13.
- the limit value of the opening angle ⁇ is reached, the first pin member 30 is received into seat 32d of engagement member 32 and re-engages with slide 22.
- the first pin member 30 applies an eccentric (with respect to axis 34) action on the engagement member 32, tending to rotate it clockwise (in the representation of figure 8a ).
- the parts can be inverted, so that the soft/self closing device 17 can ananged on the furniture door 13, and the pin member 30 arranged on the refrigerator door 5.
- the way of operating would be exactly the same.
- the elastic member 23 could be any type of device, also different from a spring, suitable to apply an axial elastic force.
- the damper 25 could be different from the one disclosed, and could be of any type suitable to apply an axial damping action.
- reciprocal position between spring 23 and damper 25 could be different from the one disclosed, as far as the two devices are able to apply the requested forces on the doors.
- the coupling device could have a different mechanism for engaging/disengaging the components of the two doors at the predetermined doors opening angle, provided that for angles lower than the limit value the elastic member is active to allow self closing of the doors and the damper is active to allow soft closing of the doors, and for angles higher than the limit value at least the elastic member is deactivated.

Abstract
A built-in household appliance assembly, comprising a household appliance (2) and a piece of furniture (10) housing the household appliance, the household appliance and the piece of furniture having respective doors (5, 13) connected in a sliding way with each other so that they can jointly rotate, around respective axes (7, 14), between a closed position where they are substantially parallel to a reference plane, and an open position where they form substantially a same rotation angle (α) with the reference plane and they allow access to an internal compartment (6) of the household appliance; the assembly further comprises a coupling device (17) arranged between the doors, which comprises an elastic member (23) and a damper (25), and has a first operating mode when the rotation angle is between 0° and a limit value and a second operating mode when the rotation angle is greater than the limit value; wherein in the first operating mode the elastic member is active to allow self closing of the doors and the damper is active to allow soft closing of the doors, and in the second operating mode at least the elastic member is deactivated.
Description
- The present invention relates to a sliding door system for built-in refrigerator having a soft/self closing device applied.
- As it is known built-in refrigerators are enclosed in a piece of furniture that copies the external shape of the refrigerator (normally the shape is a parallelepiped) and that is provided with a front door for having access to the inner parts of the refrigerator.
- The front doors are applied according to two different techniques, i.e. the so called "door on door" technique and "sliding door" technique.
- In the first case ("door on door") the door of the piece of furniture is directly applied onto the door of the refrigerator and both doors are turning around the same pivots; in other words, there is a single pivot axis for both doors.
- In the second case ("sliding door") the door of the refrigerator pivots on the body of the refrigerator and the door of the piece of furniture pivots on the piece of furniture; the pivoting axes are parallel but are spaced one with inspect to the other. A consequence of the latter system is that during doors opening/closing one door slides with respect to the other. Doors are in fact connected one with respect to the other by a connecting element that keeps the two doors approximately parallel and facing, and at the same time permits sliding between doors.
- In the "door on door" solution, a "soft closing" arrangement comprising a damper and a spring system is typically added in order to "smooth" the final movement of the door when closing.
- In the "sliding door" solution the soft closing remains an open issue as it is not clear how a damper and spring system could be used, due to the particular complexity of the door coupling structure. It should in particular be avoided that the spring could cause an undesired closure of the door when the door is at the maximum aperture.
- It is thus an object of the present invention to create a system that permits soft/self closing in "sliding door systems" without causing an unwanted closure of the door, unless the door is only slightly opened.
- The above scope is obtained by the present invention thanks to the provision of a soft/self closing device disposed between the refrigerator door and the furniture door and operating based on the value of angle that the doors form with respect to a reference plane; in a first operating mode, operated for angles lower than a limit value, the soft/self closing device applies a soft and self closing action on the two doors, while in a second operating mode, operated for angles over the limit value, the soft/self closing device does not apply any action on the doors (at least, not a self closing action). Therefore, during doors opening, when the limit angle is reached the soft/self closing device is deactivated and, during doors closing, when the limit angle is reached the soft/self closing device is reactivated.
- More in detail, the present invention relates to a built-in household appliance assembly, comprising a household appliance, such as a refrigerator or freezer, and a piece of furniture housing the household appliance, the household appliance and the piece of furniture having respective doors connected in a sliding way with each other so that they can jointly rotate, around respective axes, between a closed position where they are substantially parallel to a reference plane, and an open position where they form substantially a same rotation angle with the reference plane and they allow access to an internal compartment of the household appliance. The assembly comprises a coupling device arranged between the doors and comprising an elastic member and a damper, the coupling device having a first operating mode when the rotation angle is between 0° and a limit value, preferably comprised between 30° and 45°, and a second operating mode when the rotation angle is greater than the limit value. In the first operating mode the elastic member, which is preferably a spring, is active to allow self closing of the doors and the damper is active to allow soft closing of the doors, and in the second operating mode at least the elastic member is inactive.
- Preferably, in the second operating mode both the elastic member and the damper are inactive. In particular, the coupling device is preferably designed so that in the second operating mode the elastic member is disconnected from at least one of the doors.
- Moreover, during doors closing, when the limit value of rotation angle is reached the elastic member and the damper can be automatically reactivated.
- The coupling device may comprise a guide and a slide slidingly coupled to the guide, the guide being defined by a support body connected with a first one of said doors and the slide being designed to be selectively engaged with a second one of said doors.
- Preferably, when the limit angle is reached during door opening, the slide reaches an end position where it disengages from the second door.
- The elastic member may be coupled to the slide in such a way that when the slide moves towards said end position, the elastic member is progressively loaded.
- In a preferred embodiment, the slide is engaged with a coupling member rigidly fixed to the second door in the first operating mode and disengaged from said coupling member in the second operating mode.
- The slide may comprise an engagement member and a push member connected with each other, the engagement member being suitable to move between a first position where it engages with said coupling member and a second position where it is disengaged from said coupling member, and the push member being suitable to cooperate with a movable shaft of the damper.
- The engagement member and the push member may be hinged with each other, and the engagement member may be suitable to rotate with respect to the push member.
- The present invention also relates to an appliance suitable to form such an assembly, in particular an appliance suitable to be hosted in a piece of furniture and having a door configured to be connected in a sliding way with a door of the piece of furniture, so that the doors can jointly rotate around respective axes between a closed position where they are substantially parallel to a reference plane, and an open position where they form substantially a same rotation angle with respect to the reference plane and they allow access to an internal compartment of the appliance, According to the invention, the appliance comprises a coupling device to be arranged between the doors and comprising an elastic member and a damper, the coupling device having a first operating mode when the rotation angle is between 0° and a limit value and a second operating mode when the rotation angle is greater than the limit value; in the first operating mode, the clastic member is active to allow self closing of the doors and the damper is active to allow soft closing of the doors; in the second operating mode, at least the elastic member is inactive,
- Even though the present invention will be described with reference to a built-in refrigerator or freezer, the same can be applied to other types of built-in household appliances, for example an oven, for which the self/soft closing effect is desirable.
- The invention will be described with respect to the enclosed drawings wherein:

self closing device 17 is housed in arecess 18 of therefrigerator door 5 facing thefurniture door 13. Therecess 18 has a substantially rectangular shape, a constant depth, and is located on an exterior side of therefrigerator door 5. - Reference is now made to
figures 7a-7c ,8a-8c and9a-9c , which show (not in scale and according to different views) the soft/self closing device 17 in the first operating mode (doors closed or opened at an angle α lower than the limit value), in the instant of switching between the first and the second operating mode (doors opened at an angle α corresponding to the limit value), and in the second operating mode (doors opened at an angle α higher than the limit value), respectively, - The soft/
self closing device 17 comprises a rectangular supportingwall 20 and an elongatedhollow body 19 fixed to the supportingwall 20, or made of a single piece with it. - The
elongated body 19 is housed in therecess 18 and the supportingwall 20 is designed to close therecess 18, substantially on the plane of the doorinternal surface 5c. Theelongated body 19 and the supportingwall 20 are rigidly fixed to a base wall of therecess 18, and therefore to therefrigerator door 5, for example by means of screws (not shown). - As shown in
figure 7b , thehollow body 19 has a first and a secondlongitudinal portion lateral walls - In the first
longitudinal portion 19a of thehollow body 19, thehollow body 19 holds and houses thespring 23 and thedamper 25. Thedamper 25 has a longitudinal axis S, substantially perpendicular to pivoting axes 7, 14 (i.e. substantially horizontal), and thespring 23 is arranged below thedamper 25, side-by-side with it, with a central axis parallel to axis S. - The two
lateral walls longitudinal portion 19b of thehollow body 19, respectivelongitudinal slots 21, identical to each other and defining together a guide for a slidingmember 22 of device 17 (called simply "slide" in the following), better described later on. Theslots 21 are substantially L-shape and have respective longitudinalfirst portions 21a, defining the longer arm of the L and extending parallel to axis S, and asecond portion 21b, defining the shorter arm of the L and extending downwards from one end of thefirst portions 21a (the left end infigures 7a ,8a and9a ). - The sliding
member 22 is coupled to theguide 21 and is designed to slide back and forth along axis S between a first end position (figure 7a ) and a second end position (figures 8a and9a ). - The
spring 23 has afirst end 23a stably connected with aninternal wall 19e of theelongated body 19 in the firstlongitudinal portion 19a thereof, and asecond end 23b connected with theslide 22 in the secondlongitudinal portion 19b. - The
damper 25 comprises a tubularcylindrical body 26 stably connected, at anend 26a thereof, with abottom wall 19f of theelongated body 19, and a movable shaft 27 (seeFigures 8a and9a ) extending axially from thetubular body 26 and designed to act with itsfree end 27a on theslide 22. - As shown in
figure 10 , theslide 22 comprises apush member 31, suitable to cooperate with themovable shaft 27 of thedamper 25, and anengagement member 32, suitable to cooperate with thespring 23 and with afirst pin member 30 rigidly connected tofurniture door 13. In particular, thefirst pin member 30 is fixed to theinternal surface 13c of thefurniture door 13 by means of a fixing plate 28 (seefigures 4 ,5 and6 ) and extends from thesurface 13c towards therecess 18 of therefrigerator door 5; during doors rotation, thefirst pin member 30 is designed to slide horizontally through anelongated slot 24 ofwall 20 to which it is slidingly coupled by means of awheel 29. Theslot 24 extends parallel to thefirst portion 21a ofguide 21 and is located over the secondlongitudinal portion 19b of thehollow body 19. - The
push member 31 and theengagement member 32 are hinged with each other by means of asecond pin member 33, extending along anaxis 34 orthogonal to axis S and substantially horizontal. Thesecond pin member 33 engages, with its opposite ends, the twolongitudinal slots 21 of thehollow body 19, so as to allow the sliding coupling between theslide 22 and thehollow body 19. - The
push member 31 has a substantially planecontact surface 31a orthogonal to axis S, on which thefree end 27a ofshaft 27 abuts to apply the damping force ofdamper 25. - The
engagement member 32 is a substantially flat body extending on a vertical plane containing axis S, designed to pivot, at a first side thereof (the right side infigure 7a ), aboutaxis 34. Theengagement member 32 has three functional portions: - an
engagement portion 32a, at an upper part thereof, designed for engagement with thefirst pin member 30; - a locking
portion 32b, at a second side thereof (the left side infigure 7a ), formed by two laterally protruding elements and designed to engage with thefirst portion 21a ofguide 21 until the second end position ofguide 21 is reached, and then with a delimitingwall 21c of thesecond portion 21b ofguide 21; - a
spring coupling portion 32c; at a lower part thereof, to which thesecond end 23b ofspring 23 is rigidly fixed. - The
engagement portion 32a is forked, in particular like the head of a spanner, so as to define aseat 32d that can host thefirst pin member 30. - The two laterally protruding
elements 32b forming the locking portion extend in opposite directions along an axis parallel toaxis 34 of thesecond pin member 33 and, as previously mentioned, are suitable to engage, like thesecond pin member 33, the twolongitudinal slots 21 of thehollow body 19, when theslide 22 is moving from the first to the second stop position, or vice versa. - The
slide 22 has two operating conditions: - an engagement condition, when the soft/
self closing device 17 is in the first operating mode, wherein both theprotruding elements 32b and thesecond pin member 33 engage thefirst portion 21a ofslots 21; in this condition, rotation of theengagement member 32 is impeded (which would be caused by the pulling action ofspring 23 on thespring coupling portion 32c, as better described below) and theengagement portion 32a is engaged with thefirst pin member 30; - a disengagement condition, when the soft/
self closing device 17 is in the second operating mode, wherein the protrudingelements 32b have left thefirst portion 21a ofslots 21 and theengagement member 32 has rotated by effect of the pulling action ofspring 23; in particular, the protrudingelements 32b are inside thesecond portion 21b ofslots 21 and abut againstwalls 21c, thus avoiding further rotation; in this condition, theengagement portion 32a is disengaged from thefirst pin member 30. - The
slide 22 is configured to slide alongguide 21 between the first stop position (figure 4 andfigures 7a-7c ), at the right end ofguide 21 in the representation offigure 7 , where it is in the engagement condition and where thespring 23 is not tensioned (or is tensioned to a small extent), and the second stop position (figures 5 ,6 ,8a-8c and9a-9c ) at the left end ofguide 21, where it is in the disengagement condition and where thespring 23 is tensioned. - The soft/
self closing device 17 operates as follows. - When the
doors slide 22 is in the first stop position and in the engagement condition (figures 7a-7c ), wherein it is coupled with thefirst pin member 30. In this condition, thespring 23 is not tensioned (or slightly tensioned) and thedamper 25 is ineffective. - As a user opens the doors 3,13 (by applying a pulling force to the
furniture door 13, which is transmitted to therefrigerator door 12 by the sliding connection device 16), the linear displacement of one door with respect to the other causes the sliding movement of thefirst pin member 30 in theslot 24 and, as thepin member 30 mates with theengagement portion 32a ofslide 22, a corresponding dragging movement ofslide 22 along theguide 21. In particular, theslide 22 slides horizontally, as thesecond pin member 33 and the protrudingmembers 32b both engage thefirst portion 21a ofslide 21, - During this movement of
slide 22, thespring 23 is progressively stretched and tensioned, while theshaft 27 of thedamper 25 simply follows this movement. In this phase (where the doors opening angle α is lower than the limit value), the soft/self closing device 17 works in the first operating mode, wherein thedamper 25 and thespring 23 are active between the first and thesecond door furniture door 13 andrefrigerator door 5 is in fact established throughpin member 30 carried byfurniture door 13, slide 22 mated withpin member 30,damper 25 andspring 23 both connected withslide 22, andelongated body 19 carried byrefrigerator door 5. - If the door opening is stopped before the limit value of angle α is reached, the soft/
self closing device 17 keeps working in the first operating mode. In this condition, if the user leaves thedoors spring 23 pulls back theslide 22 towards the first stop position, and theslide 22 drags thefirst pin member 30 in this movement. Accordingly, thedoors slide 22, thedamper 25 applies its damping action on theslide 22 thanks to the force applied by theshaft 27 on thepush member 31. Therefore, the combined action of thespring 23 anddamper 25 accomplishes a self and soft closing action. - The damping action is applied also if the user, instead of leaving the
doors doors spring 23. - When the
doors self closing device 17 would keep working in the first operating mode and the progressive spring loading would result in an excessive return force hampering further opening of the doors and tending to close them in a violent way. This would be unpleasant and potentially dangerous. - According to the present invention, the above effect is avoided thanks to the mechanism that switches, during door opening, the soft/
self closing device 17 from the first operating mode to the second operating mode when the limit value of the opening angle α is reached. In particular, this switching mechanism deactivates thespring 23, so that in the second operating mode not only a further rotation of thedoors 5, 13 (and thus a further displacement of one door with respect to the other) cannot cause further tensioning of thespring 23, but also thespring 23 has no more action on thefurniture doors 13. Advantageously, also thedamper 25 is no more operative_ as from the above limit value of opening angle α, since in the second operating condition of the soft/self closing device 17 theslide 22 is disengaged from thefirst pin member 30 and rests in the second stop position. In other words, the above disclosed connection chain between the two doors is interrupted by the disengagement of thepin 30 from theslide 22. - This switching mechanism works as follows.
- As shown in
figures 8a-8c , as theslide 22 approaches the second stop position, the twoprotrusions 32b of theengagement member 32 leave thefirst portion 21a ofguide 21, so that theengagement member 32 is no more impeded from rotating about theaxis 34 of thesecond pin member 33 under the action ofspring 23 and under the eccentric (with respect to axis 34) action of thefirst pin member 30. In other words, theslide 22 becomes unlocked. - Accordingly, the
engagement member 32 rotates (counter-clockwise in the representation offigure 8a ) and the two protrudingmembers 32b move into thesecond portion 21b ofguide 21, where they abut against thewall 21c. Now, with the slide in the second stop position, the soft/self closing device 17 is in the second operating condition, wherein thefirst pin member 30 is disengaged fromslide 22 and can then move freely (direction B infigure 6 during door opening) along slot 24 (figure 6 ,figures 9a-9c ). In this condition, for doors opening angle α over the limit value, thedoors - When closing the
doors self closing device 17 works in the second operating mode, in which both thespring 23 and thedamper 25 are inactive, until the limit value is reached. Then, the soft/self closing device 17 switches back from the second operating mode to the first operating mode, by the re-activation of thespring 23 and thedamper 25. Accordingly, thespring 23 restarts applying a force on thedoors damper 25 restarts applying a damping effect to smooth door closing. In other words, door closing with soft/self closing effect is performed as above outlined. - More in detail, during door closing starting from an opening angle α over the limit value, the
first pin member 30 initially moves freely alongslot 24, and no self/soft closing action is applied to thedoors first pin member 30 is received intoseat 32d ofengagement member 32 and re-engages withslide 22. By this engagement, thefirst pin member 30 applies an eccentric (with respect to axis 34) action on theengagement member 32, tending to rotate it clockwise (in the representation offigure 8a ). When, by effect of this rotation, the protrudingelements 32b leave thesecond portion 21b ofguide 21 and engage with thefirst portion 21a, theslide 22 can start sliding alongguide 21, subject to both pulling action of the spring 23 ("self closing" action) and damping action of damper 25 ("soft closing" action). - Therefore:
- when the doors opening angle α is higher than the limit value, the two
doors doors - when the doors opening angle α is higher than the limit value, the following additional actions are automatically applied between the two
doors doors connection device 16, to rotate them together towards the closed position; and a smoothing force (generated by the damper 25) acting opposite the retraction force to reduce its action. - The embodiment of the present invention previously described is only a possible example of application, and various modifications can be applied to it.
- For example, the parts can be inverted, so that the soft/
self closing device 17 can ananged on thefurniture door 13, and thepin member 30 arranged on therefrigerator door 5. The way of operating would be exactly the same. - The
elastic member 23 could be any type of device, also different from a spring, suitable to apply an axial elastic force. - Similarly, the
damper 25 could be different from the one disclosed, and could be of any type suitable to apply an axial damping action. - Also the reciprocal position between
spring 23 anddamper 25 could be different from the one disclosed, as far as the two devices are able to apply the requested forces on the doors. - Moreover, the coupling device could have a different mechanism for engaging/disengaging the components of the two doors at the predetermined doors opening angle, provided that for angles lower than the limit value the elastic member is active to allow self closing of the doors and the damper is active to allow soft closing of the doors, and for angles higher than the limit value at least the elastic member is deactivated.
