Definitions

  • the present invention concerns to the field of manufacturing of hinged or sliding fixtures and relates to a draft stopper device to be mounted on doors of various types, as well as to a method for manufacturing said device.
  • a solution to these known drawbacks of the present state of the art consists in the use of a small step on the floor which acts as a bottom stop for the door. It is possible to mount on the step or on the corresponding bottom edge of the door a strip of elastic material which ensures the absence of gaps and prevents the penetration of air drafts and noise.
  • the main drawback of this solution is that the step on the floor, although small, may constitute an obstacle when passing through the doorway and may be dangerous if not seen.
  • a further drawback of this solution consists in the fact that this step may be unaesthetic and visually unattractive.
  • EP-A-0940551 describes a constructional example of an alternative solution.
  • a flexible element is mounted on the bottom edge of the door so that it remains in contact with the floor and closes the gap between the door and the floor.
  • This flexible element may consist of a brush.
  • a drawback of this solution is that the flexible element, since it always rubs along the floor, is prone to get dirty and wear out quickly and therefore lose its effectiveness.
  • the force of contact between the flexible element and the floor must be limited so as not to be troublesome during opening and closing of the door.
  • EP-A-0916802 and EP-A-0915226 An alternative solution is described in EP-A-0916802 and EP-A-0915226.
  • a fixed profile with a U-shaped cross-section is secured onto the bottom edge of the door and a movable profile with a U-shaped cross-section is placed inside it.
  • the movable profile is retained by a recall spring inside the door and at a certain distance from the floor.
  • a mechanism causes the movable profile to come out from the bottom edge of the door and come into contact with the floor, thereby preventing the passage of air and noise.
  • a first drawback of this device consists in the fact that the movable profile has an open cross-section which is less rigid than a closed cross-section. In order to remedy this lack of rigidity due to the shape of the profile, it is advisable to use a rigid material.
  • a rigid material, such as metal is more costly than a material, such as plastic, having inferior mechanical properties.
  • a third drawback is associated with the fact that the force requires to actuate the mechanism and cause the movable profile to come out of its seat increases considerably with an increase in the movement imparted to the profile. As a result, particularly in the case of sliding doors, the sliding force required to close the door could cause it to spring back instead of remaining locked in position.
  • a fourth problem of this device may arise when the movable profile is in the lowered position in contact with the floor.
  • the draft stopper device may become less effective owing to the play present between the movable profile and the fixed profile. Undesirable air drafts and sound waves may pass through owing to this internal play in the device.
  • a main object of the present invention is that of eliminating the abovementioned drawbacks by providing a draft stopper device suitable for hinged or sliding doors and windows.
  • a general object is that of providing a draft stopper device which is effective and, at the same time, inexpensive to produce.
  • a particular object is that of providing a draft stopper device which prevents air from passing between the bottom edge of a door and the floor and is able to increase the overall acoustic insulating capacity of the door in the closed configuration.
  • a particular object is that of providing a draft stopper device which is easy to operate and does not create any obstacle to the movement of the door on which it is mounted nor any difficulty during closing.
  • a further particular object is that of providing a draft stopper device whose operating characteristics remain unchanged, without any appreciable reduction in performance.
  • a draft stopper device particularly for hinged or sliding doors and similar fixtures, comprising a first elongated fixed profile with a cross-section substantially in the form of an overturned U, which can be secured to the bottom edge of a door, a second movable profile inserted inside said fixed profile with a limited degree of transverse movement with respect thereto, fastening means able to connect together said fixed profile and said movable profile and limit said transverse movement, automatic actuating means able to move said movable profile away from said fixed profile and bring it into contact with the floor when the door is in the closed position, elastic opposing means for moving said movable profile towards said fixed profile when the door is in the open position, characterized in that at least said movable profile is made entirely of plastic material and has a box-shaped portion with a closed cross-section for increasing its flexural and torsional rigidity.
  • the draft stopper device according to the invention is able to improve the overall acoustic insulation provided by the door in the closed configuration and facilitate the movement of the door on which it is mounted, while maintaining substantially unchanged operating characteristics, without any appreciable reduction in performance.
  • a draft stopper device is shown according to the invention, denoted in its entirety by the reference number 1, which may be mounted on the bottom edge of a fixture of the type consisting of a hinged or sliding door or window.
  • the device 1 essentially comprises a fixed, elongated, profile 2 with a cross-section substantially in the form of an overturned U and with a longitudinal axis L, which can be secured to the bottom edge B of the door P and inside which a movable profile 3 is slidably inserted, with the possibility of a limited transverse movement with respect to the fixed profile 2.
  • the movable profile 3 is operatively coupled to the fixed profile 2 by means of suitable fastening means - denoted overall by 4 and 5 - which are able to limit the abovementioned relative transverse movement.
  • the fastening means 4, 5 may consist of pair of arms 6, 7, each having one end 8, 9 hinged with the movable profile 3 and the other end 10, 11 joined to the fixed profile 2.
  • the arms 6, 7 are slightly inclined with respect to the longitudinal direction of said profiles at angles of inclination ⁇ , ⁇ which are substantially equal and opposite.
  • the ends 10, 11 of the arms 6, 7 are joined to the fixed profile 2 by means of respective rotatable supports 12, 13 which have an elongated shape and consist of profiled portions with a suitable cross-section, which can be inserted into a counter-shaped longitudinal seat 14 of the fixed profile 2.
  • Elastic opposing means are provided for moving the movable profile 3 towards the fixed profile 2 when the door P is in the open position.
  • these opposition means may consist of a pair of extension springs 15, 16 having a first end 17, 18 fixed to each of the arms 6, 7 and the other end 19, 20 fastened to a respective rotatable support 12, 13.
  • Automatic actuating means denoted overall by the reference number 21, are also envisaged, said means being able to operate the movable profile 3 so as to move it transversely away from the fixed profile 2 and bring it into contact with the floor T when the door P is in the closed position.
  • the movable profile 3 is made entirely of plastic material and has a box-shaped portion 22 with a closed cross-section so as to increase its flexural and torsional rigidity.
  • the closed cross-section comprises a pair of side walls 23, 24 which are joined together by transverse walls 25, 26.
