Definitions

  • the present invention relates to the field of mechanisms for actuating sliding parts of pieces of furniture or fixtures, such as, for example, furniture doors, wardrobes, walk-in closet doors or drawers.
  • the present invention relates to a braking device of the opening or closing movement of a sliding part of a piece of furniture or fixture.
  • the invention further relates to a piece of furniture comprising a braking device according to the present invention.
  • each of these sliding parts is actuated by the use of one or more trolleys fixed to the part itself and provided with actuating wheels.
  • the latter allow the movement of the trolleys along guides/rails arranged on the top or bottom surface of the wardrobe or fixture according to the cases. Such a movement of the trolleys thus translates into an actuation of the sliding part.
  • the actuation of the sliding part is limited between two limit stop positions defined by appropriate stop members.
  • such an actuation is clearly accompanied by the need to brake/slow down the sliding part when it approaches one of the limit stop positions. Otherwise, a collision of the sliding part against the limit stop could indeed cause damage to the latter.
  • the possible stress produced in case of collision between the sliding part and the limit stops may also damage the actuating trolleys of the sliding part and in some conditions even the guides/rails on which the trolley themselves run.
  • braking devices which allow to slow down the sliding part during both the opening and closing movement.
  • An example of such braking devices includes a containment box inside which two opposed braking devices are arranged, each of which adapted to brake one of the movements of the sliding part of the furniture or of the fixture with which the braking device is associated.
  • Each braking device is of the viscous fluid type and has a hub directly meshing with a rack made integral with the containment box.
  • each braking device is associated with a slider which is guided by the containment box and is associated with an end of one or more of the helical springs having the opposite end associated with the other slider. Both sliders comprise a hook, which interacts with a fixed member of the piece of furniture or the fixture to block the respective slider.
  • This braking device has several limits, the first of which is identified in the presence of two braking means of the viscous fluid rotation type. Indeed, while being relatively effective from the functional point of view, this solution is a critical factor from the economic point of view, given the high cost of devices of this type. Furthermore, the presence of two braking devices constitutes a constraint also in dimensional terms because it necessarily imposes a given length of the rack, i.e. of the box with which the rack is integral. With this regard, it is noted that also the position of the helical springs, intermediate between the two sliders, is a critical factor for the dimensions of the containment box because it necessarily imposes a rather considerable minimum distance between the two sliders.
  • a first object of the present invention to provide a braking device which is made with a relatively low number of components, which are easy to assemble.
  • Another object of the present invention is to provide a braking device which is functionally versatile, i.e. can be used for a high number of applications.
  • a not last object of the present invention is to provide a braking device which is reliable and easy to make at competitive costs.
  • a braking device for the opening and closing movement of a sliding part of a piece of furniture or fixture according to claim 1.
  • the braking device according to the invention comprises:
  • first and second sliders comprising a first sliding body and a second sliding body, respectively, sliding within the box along a sliding direction, said first slider and said second slider comprising a first locking/unlocking member and a second locking/unlocking member, respectively, outside the containment box.
  • the device according to the invention further comprises a rack integral with the first slider and a rotating braking member housed in a first seat defined by the second slider, such a rotating braking member comprises a pinion portion engaged with the rack.
  • the braking device also comprises at least a first constant- intensity spring operatively connecting the first slider to the second slider.
  • the braking device according to the invention comprises an advantageously low number of components which increase its reliability while limiting manufacturing costs at the same time.
  • the mechanism advantageously contemplates a single rotating braking member in viscous fluid.
  • the device is particularly compact and thus extremely versatile from the functional point of view. It is noted, for example, that a device according to the invention being of longitudinal extension of approximately 340 mm may be used to actuate both doors with longitudinal extensions greater than 800 mm, thus very big, and doors of approximately 350 mm in size, thus relatively small. The range of possible applications is thus advantageously wide.

  • figure 3 is a second exploded view of a second view point of the device in figure 1 ;
  • figure 4 is a second perspective view of the device in figure 1 ;
  • FIG. 5 is a view of a door of a piece of furniture, in a closing position, to which the braking device according to the invention is applied;
  • FIG. 6 is a front view of the braking device associated to the door in figure 5 in a characteristic configuration of the closing position of the door itself;
  • FIG. 7 is a view of the door of the piece of furniture in figure 5 during the transition of the same from a closing position to an opening position;

  • the device 1 is particularly suitable for braking/damping the opening and closing movement of a door of a piece of furniture or of a door of a walk-in closet.

  • the first locking/unlocking member 1 1 is coupled to the first sliding body 41 by means of first coupling means which define a first rotation axis X1 for the same first member 1 1 with respect to the first sliding body 41 .
  • first coupling means are defined by a peg-shaped portion 81 of the first locking/unlocking member 1 1 and a seat 81 ' defined by the first sliding body 41 in which the peg-shaped portion 81 is inserted.
  • the first locking/unlocking member 1 1 comprises a first shaped portion 13 adapted to be coupled/uncoupled to a first striker 91 integral with the piece of furniture 8 with which the door 9 is associated.
  • the first locking/unlocking member 1 1 further comprises a first guiding pin 31 sliding within a guiding groove 3 defined on the outer side of the second surface 62 of the main body 51 of the containment box 5.
  • a guiding groove 3 (visible in figure 3) comprises a straight central section 3' and two end curved sections 3", 3"' which are developed from the straight section 3' so as to be reciprocally opposite.
  • the sliding of the first guiding pin 31 in the straight section 3' is characteristic of a locking condition of the first member 1 1 to the first striker 91 , i.e. a locking condition of the first slider 10 to the piece of furniture 8.

  • the structure of the second locking/unlocking member 21 is substantially equivalent to that of the first locking/unlocking member 11. Therefore, the second coupling means are equivalent to the above-described first coupling means and comprise a second peg-shaped portion 82 of the second locking/unlocking member 21 and a seat 82' defined by the second sliding body 42 in which such a second peg-shaped portion 82 is inserted.
  • the second locking/unlocking member 21 comprises a second shaped portion 23 adapted to be coupled/uncoupled to/from a second striker 92 integral with the piece of furniture 8 with which the door 9 is associated.
  • the second locking/unlocking member 21 comprises a second guiding pin 32 sliding inside the above-defined guiding groove 3.
  • the sliding of the second pin 32 in the straight section 3' is characteristic of a locking condition of the second member 21 , i.e. a locking condition of the second slider 20 to the piece of furniture 8.

  • the first spring 71 is charged with elastic energy because the end 71 remains integral with the first slider 10.
  • the first spring 71 is extended in the sliding direction X outside the second seat 35 in a position above the second sliding body 42 of the second slider 20 (see figure 3) to be connected to the connecting end 77 in a position above the first sliding body 41 .
  • a constant-intensity spring like the one illustrated and described above makes the device 1 particularly reliable from the functional point of view and also extremely compact.
  • the second seat 35 could be defined by the first slider 10. In this case, the connecting end of the spring would remain connected to the second sliding body 42 of the second slider 20.

  • the use of two springs 71 , 72 is particularly advantageous as it allows to contain the overall dimensions of the braking device 1. Indeed, with the total required force being equal, the transversal and longitudinal dimensions of the two springs 71 , 72 can be reduced in the case in which the use of one spring only is provided.
  • a connecting end 77' of the second spring 72 is connected to the first sliding body 41 of the first slider 10 in a position adjacent to the above-indicated connecting end 77 of the first spring 71.
  • the connection of the connecting ends 77, 77' of the springs 71 , 72 can be made by means of any fastening member 73 suited to the purpose.
  • the first sliding body 41 of the first slider 10 comprises a first resting portion 46 intended to rest on the inner side of the second surface 62 of the first body 51.
  • the expression "inner side” indicates the side of the second surface 63 facing the inner volume of the containment box 5.
  • the first sliding body 41 also comprises a first guiding portion 47, which emerges from the containment box 5 in a position adjacent to the outer side of the second surface 62 of the main body 51 , as shown in figure 4.
  • Such a first guiding portion 47 increases the movement stability of the first sliding body 41 of the first slider 10, thus allowing it to maintain a portion essentially vertical with respect to the second surface 62 thus preventing it from tipping or in all cases reducing the instability which could derive from the presence of the longitudinal opening 4.
  • the first sliding body 41 indeed rests with the first resting portion 46 on the inner side of the second surface 62 and by effect of the first guiding portion 47 rests stably adjacent to the edge 62' of the second surface 62 of the main body 51.
  • Such an edge 62' substantially guides the sliding in longitudinal direction X of the first sliding body 41.
  • the second sliding body 42 of the second slider 20 comprises a second resting portion 46' intended to rest on the upper side of the second surface 62 of the main body 51 of the containment box 5 in manner similar to that provided for the first slider 10.
  • the second sliding body 42 also comprises a second guiding portion 47' (indicated in figure 4), which emerges outside the containment box 5 in a position adjacent to the outer side of the second surface 62.

  • the braking device 1 is connected to the door 9 in an intermediate position between the two trolleys 85.
  • a first striker 91 in the form of a peg is located in a first longitudinal position adjacent to the rails 92 for interacting with the first locking/unlocking member 1 1 of the first slider 10.
  • a second striker 92 in the form of a peg is arranged in a second longitudinal position distanced from the first striker 91 by a predetermined longitudinal length L.
  • the second peg-shaped striker 92 is inserted in the second shaped portion 23 of the second locking/unlocking member 21 of the second slider 20 so as to lock the slider 29 itself to the piece of furniture 8.
  • Figure 6 allows to observe the position assumed by the various internal components of the containment box 5 of the braking device 1 in the closing position. As shown in this configuration, the two sliders 10, 20 are in a position close to the first side 64 of the box 5 and at an extremely short distance with respect to the longitudinal extension L1 of the containment box 5. Such a close position may be advantageously reached by virtue of the position assumed by the springs 71 ,72 with respect to the sliders 10,20 which does not limits its reciprocal approach. It is indeed noted that in the closing position the pinion portion 18' of the braking member 18 meshes with the rack 15 in a position substantially adjacent to the first sliding body 41 of the first slider 10.
  • the constant- intensity springs 71 ,72 are in a substantially resting condition. Furthermore, the first guiding pin 31 of the first locking/unlocking member 1 1 is inserted in the first curved end section 3' of the guiding groove 3. This in fact make the first slider 10 integral with the containment box 5. The second pin 32 of the second locking/unlocking member 21 is instead inserted in the straight section 3' of the same guiding groove 3. Such a condition in fact makes the containment box 5 (and thus the first slider 10) free to slide with respect to the second slider 20, which is locked instead by the second striker 92 to the piece of furniture 8.
  • the loading of the springs 71 ,72 is completed when following the sliding of the containment box 5, the second pin 32 integrates with the second end section 3"' of the groove 3, the shape of which determines a movement of the second pin 32 which translates into a rotation of the second locking/unlocking member 21 about the second rotation axis X2. Such a rotation unlocks the shaped second part 23 of the second locking/unlocking member 21 from the second striker 92, thus releasing the second slider 20 from the piece of furniture 8.
  • Figures 7 and 8 illustrate the braking device 1 after the second slider 20 has been released from the piece of furniture 8.
  • the two sliders 10, 20 are both restrained to the containment box 5 and have the maximum reachable reciprocal distance.
  • the pinion portion 18' of the braking member 18 meshes with the rack 15 in proximity of the end part of the same, i.e. at the maximum distance from the first sliding body 41 of the first slider 40. It is noted that the springs 71 ,72 of the braking device 1 are both loaded to the maximum.
  • the braking device 1 assumes the configuration shown in figures 9 and 10. It is noted that the two sliders 10, 20 assume a minimum distance again similarly to the relative configuration in figures 5 and 6. In this case, however, the two sliders 10, 20 assume a position inside the containment box 5 close to the second side 64' of the first body 51 .
  • the operation of the device during the closing step of the door 9 is essentially similar to that described above related to the opening.
  • the closing of the door 9 occurs by exerting, for example, a force in the direction indicated by arrow F2 in figure 9.
  • the first slider 10 is locked to the piece of furniture 8 by means of the first striker 91 which improves the movement thereof by interacting with the first locking/unlocking member 1 1 .
  • the containment box 5 and the second slider 20 move with respect to the first slider 10, loading the springs 71 , 72 until the configuration related to figures 7 and 8 in which both sliders 10, 20 are integral with the box 5 is reached.
  • the device according to the present invention is extremely compact and formed by a low number of components which are easy to assemble to one another.
  • the braking device according to the invention is also reliable and functionally very versatile by virtue of the limited longitudinal dimension which allows the use thereof in a wide number of applications.
  • the braking device thus devised is susceptible to a number of changes and variants all within the scope of the inventive concept; furthermore, all details may be replaced by other technically equivalent ones.
