Definitions

  • the present invention relates to the technical field of closing systems, and in particular it relates to a system for the damped closing of a sliding door or door leaf, in particular a glass sliding door or door leaf of a refrigerator cabinet.
  • the invention relates to a refrigerator cabinet on which this system is mounted.
  • document US2016324335A1 discloses one of these systems, which includes magnetic damping means and a counterweight suitable to promote the return of the sliding door leaf or door to the closed position once opened.
  • a further disadvantage lies in the fact that in case of minimum openings of the sliding door leaf or door, like it often happens in a supermarket when the customer opens the refrigerator cabinet to pick the product closest thereto, the closing weight force could be insufficient to ensure the complete closure of the sliding door leaf or door.
  • the object of the present invention is to overcome the drawbacks outlined above by providing a system for the damped closing of a sliding door or door leaf that is highly effective and relatively cost-effective.
  • a further object of the present invention is to provide a system for the damped closing of a sliding door or door leaf with minimum overall dimensions.
  • a further object of the present invention is to provide a system for the damped closing of a sliding door or door leaf with high aesthetic appeal.
  • a further object of the present invention is to provide a system for the damped closing of a sliding door or door leaf capable of always guaranteeing the return of the sliding door leaf or door to the closed position, even in case of minimum opening.
  • a further object of the present invention is to provide a system for the damped closing of a sliding door or door leaf that is easy to assemble.
  • the stationary support structure may be a refrigerator cabinet F, for example as illustrated in FIG. 1 , a vertical refrigerator cabinet of the type present in supermarkets or the like or, as illustrated in FIG. 4 or 5 , a horizontal well refrigerator.
  • the stationary support structure may be a frame T or a cover C of the refrigerator F.
  • the opening P may be an access compartment in the refrigerator cabinet F.
  • the opening P is defined by a substantially vertical or horizontal plane, and one or more door leaves or panels 10, generally configured as an insulated glazing or a flat or curved monolithic sheet, slide in this sliding plane to close or open the opening P.
  • the door leaf or panel 10 may be generally rectangular-shaped with a pair of substantially horizontal edges 11, 11' and a pair of substantially vertical edges 12, 12'.
  • One of the substantially horizontal edges 11, 11', and preferably the upper one 11, may be inserted into an element 20 suitable to guide the sliding of the door leaf 10 by means of appropriate sliding wheels 13.
  • the stationary support structure of the system 1 may consist of the sliding element 20, which in turn may be fixed to the refrigerator F.
  • the guide element 20 may have at least one guide wall 22 of the sliding wheels 13.
  • the guide element 20 may be a single or double capsized generally U-shaped rail with a bottom wall 21, two facing side walls 22, 22' and an opening 23 opposite to the bottom wall 21.
  • the bottom wall 21 and the two facing side walls 22, 22' may define the inner surface of the guide rail 20.
  • the guide element 20 may be arranged above or below the door leaf or panel 10, and therefore the bottom wall 21 may be upper or lower with respect to the door leaf or panel 10, without departing from the scope of protection of the attached claims.
  • the guide element may be shaped to form a U or a capsized U.
  • the guide element 20 may provide for a guide wall 22 and an abutment wall 21, while in the embodiment of FIGS. 5a and 5b the guide element 20 may provide for a horizontal guide wall 22.
  • a transmission pulley 14 and the main body 15 of a damping device 40 may be fixed to the upper edge 11 of the door leaf or panel 10. Both the transmission pulley 14 and the damping device 40 may slide integrally joined with the door leaf or panel 10.
  • the transmission pulley 14 may be idle, so as not to exert any braking action on the elastic cord 30.
  • both the transmission pulley 14 and the damping device 40 may be positioned in any manner.
  • the transmission pulley 14 and the damping device 40 may be positioned in any manner.
  • FIGS. 5a and 5b are both fixed to the stationary support structure C.
  • Means for the elastic return of the door leaf or panel 10 from the open position towards the closed position, for example once opened manually by a user, may also be provided for.
  • These elastic return means may comprise or consist of one or more elongated elastic elements 30, for example a rope, a cord or elastic band.
  • the elongated elastic element may be of any type and it may vary in number without departing from the scope of protection of the attached claims.
  • the end 31 of the elastic cord 30 may be fixed to the guide element 20, for example to the wall 21 or 22, while the opposite end 32 may be fixed to the door leaf or panel 10 through the damping device 40. More particularly, the end 32 of the elastic cord 30 may be fixed to the main body 15 of the damping device 40, which is in turn fixed to the upper edge 11 of the door leaf or panel 10.
  • the elastic cord 30 may have an intermediate portion 33 engaged in the pulley 14.
  • the aforementioned configuration allows the elastic cord 30 to return the door leaf or panel 10 towards the closed position once opened.
  • the point for fixing the end 31 to the guide element 20 and the point for fixing the transmission pulley 14 to the edge 11 may be positioned on opposite sides with respect to the substantially perpendicular median plane IIIb - IIIb passing through the door leaf or panel 10 and the guide element 20, while the point for fixing the end 32 to the edge 11 may be interposed therebetween.
  • any damping means not necessarily the device 40, may be provided for.
  • the end 32 may be connected to the door leaf or panel 10 in any position and in any manner, directly or indirectly for example by means of a plate or eyelet integrally joined with the door leaf or panel 10.
  • the system 1 may include the damping device 40, which - during the sliding thereof integrally joined with the door leaf or panel 10 - is designed to interact with an activation pin 41 internally fixed to the guide element 20 so as to be selectively activated when the door leaf or panel 10 is in proximity of the closed position.
  • no braking means shall act on the elastic cord 30 before the interaction of the damping device 40 with the activation pin 41, so that the interaction between the latter occurs with a force sufficient to activate the damping device 40 properly.
  • damping device 40 and the activation pin 41 may be equivalently fixed respectively to the stationary support structure and to the door leaf or panel 10 without departing from the scope of protection of the attached claims.
  • the device 40 is per se known in the industry by the name "soft close”, and it may have a generally plate-like main body 15, that is defining a plane, with an abutment element 42 designed to selectively interact with the activation pin 41 to move from an inoperative position, that it takes for example when the door leaf or panel 10 is in the open position, to an operative position, that it takes for example upon interacting with the pin 41.
  • FIG. 6a illustrates the closed position of the door leaf or panel 10 with the abutment element 42 in operative position
  • FIG. 6b illustrates the closing movement of the door leaf or panel 10, with the abutment element 42 in inoperative position just before interacting with the activation pin 41.
  • the abutment element 42 may be a tooth or similar element suitable to impact against the activation pin 41 during the sliding of the main body 15.
  • the abutment element 42 may be connected with a damper 43, for example a gas damper, consisting of a jacket 44 and a stem 45.
  • a damper 43 for example a gas damper, consisting of a jacket 44 and a stem 45.
  • the activation element 42 may also be connected with a traction spring 46. Furthermore, in a per se known manner, during the movement thereof, the activation element 42 may be guided in a curved guide element 47.
  • the activation pin 41 may be interposed between the fixing point of the end 31 and the damping device 40.
  • the generally plate-like main body 15 of the device 40 may be fixed to the edge 11 of the door leaf or panel 10, by means of a C-shaped bracket, parallel to the edge 11, also substantially flat.
  • the generally plate-like main body 15 will be substantially perpendicular to the side walls 22, 22' and substantially parallel to the bottom wall 21.
  • the damped closing system described above actually has minimum overall dimensions, and it is entirely contained inside the guide element 20.
