Definitions
- the present invention relates to the field of doors or windows and more precisely it relates to a sealing member for sliding elements, such as doors, windows, panels of closets, etc. of the type capable of moving between a closed configuration and an open configuration.
- Sliding doors or windows generally refer to a variety of types of doors, windows and similar items comprising one or more panels that slidingly engage on a rectangular fixed frame parallel to each other.
- the fixed frame is formed by a profiles bar from whose perimeter protruding guides extend towards the inside.
- the panels which are also obtained by profiles elements, engage with the guides by means of grooves or longitudinal housings provided on their outer perimeter. More precisely, the guides provided on two opposite sides of the frame have a function of rail for the panels and a sealing function, whereas the guide provided on the other two opposite sides of the frame have a function of abutment and a sealing function.
- sealing elements and rolling elements are provided, for example bearings, whereas in the other housings sealing elements and abutment elements are provided, for example cushioning flexible material.
- sealing elements and abutment elements are provided, for example cushioning flexible material.
- the sliding elements can be mounted in the housings of the panels to engage with on the side faces of the guide or, vice-versa, they can be mounted on the side faces of the guide to engage with the inner walls of the housings of the panels.
- the guide can be made on the sliding panels instead of the fixed frame, which provides in turn grooves or housing, interchanging the respective functions.
- sealing sliding elements strips of textile fibres are used, like felt, or bristles are used, known in the field as brush sealing members.
- Brush sealing members 120 tend to deform with the use.
- their alternated movement within profiles 141 and 142 causes an alternate bending of the bristles 122 against the guide 145 or an oblique permanent bending thereof, (see figure 2 ) that with time causes a permanent deformation with high reduction of the sealing properties and require, also in this case, to be changed.
- sealing sliding elements used up to now do not provide an airtight, a water and acoustic insulation.
- sealing member for sliding elements, such as doors, windows, sliding panels, according to the invention, with improved features versus airtight, water and acoustic insulation, said sealing member being connected to a support surface of a door or window and sliding in use against a sealing surface of said door or window, said support surface and said sealing surface slidingly engaging with each other having said sealing member sandwiched between them, whose characteristic is that it comprises:
- a sliding element such as a door, window, sliding panel
- a sealing member with improved features versus airtight, water and acoustic insulation
- said sealing member being connected to a support surface of said door or window and sliding in use against a sealing surface of said door or window, said support surface and said sealing surface slidingly engaging with each other having said sealing member arranged between them, whose main feature is that said sealing member comprises:
- the support surface can be determined on a first profile and the sealing surface on a second profile, said first and second profile slidingly engaging with each other.
- the sealing surface can be made on the first profile at a guiding head and the support surface at the second profile, said second profile comprising a housing where said guiding head slidingly engages, between said guiding head and said housing being arranged said sealing member.
- the support surface is made on the first profile at a guiding head and the sealing surface is made on the second profile, said second profile comprising a housing where said guiding head slidingly engages.
- the support surface can be made at a first panel, for example of a door or window a piece of furniture, and the sealing surface at a second panel, said first and said second panel sliding relative to each other.
- the support surface is made at a fixed frame of a door or window, said sealing surface being arranged on an element that slides with respect to said fixed frame.
- the sealing surface is made on the fixed frame and the support surface is arranged on an element that slides with respect to said fixed frame.
- the profile of flexible material has a projection adapted to snap engage with a groove made on said support surface.
- the profile of flexible material is constrained to the support surface by a adhesive surface, for example an adhesive tape, a layer of glue, etc.
- the flexible material is selected from the group comprised of:
- the material with a low friction coefficient is selected from the group comprised of:
- the profile of flexible material is obtained through an extrusion process.
- the layer with a low friction coefficient having also a high resistance against the wear, is made by a electrostatic deposit process of a plurality of fibres of a material with a low friction coefficient on a substrate.
- said substrate is connected to said flexible material by gluing, heat pressing, rolling, coextrusion, etc.
- the layer with a low friction coefficient is made by a electrostatic deposit process of a plurality of fibres of a material with a low friction coefficient directly on the profile of flexible material.
- the layer with a low friction coefficient is obtained by arranging a layer of varnish having a low friction coefficient on the profile of flexible material. Said layer being applied by a spraying, rolling, coextrusion step.
- a first exemplary embodiment is shown of a structure of sliding element 1, for example a door, a window, a sliding panel of a piece of furniture, to which a sealing member according to the invention can be applied.
- the sliding door or window 1 of figure 3 comprises a support surface 11 made on a fixed frame 25 and a sealing surface 12 made on a door 15 slidingly mounted on the fixed frame 25. More in detail, between the support surface 11 of frame 15 and the sealing surface 12 of door 25 sealing member 20 is arranged. It comprises a profile of flexible material 21, for example an extruded profile of EPDM, coupled to a coating layer made of a material with a low friction coefficient 22, for example less than 0.5.
- the coating layer 22 can be obtained by an electrostatic deposit process of a plurality of fibres of a material with a low friction coefficient, for example polyamide, on a substrate.
- the coating layer 22 can be obtained by arranging a layer of varnish characterized by a low friction coefficient on the profile of flexible material 21.
- the profile of flexible material 21 can be indifferently connected to frame 15, as shown in figure 3 , or alternatively, to door 25.
- the sealing member 20 remains still on frame 15, door 25 slides and the layer of material with a low friction coefficient 22 moves against the surface 12 of door 25.
- the sealing member 20 is connected to door 25 and when sliding the layer of material with a low friction coefficient 22 slides against surface 11 of frame 15.
- the sealing member 20 thus obtained, of which in figures from 6 to 8 some possible exemplary embodiments are shown, allows to limit the friction when surfaces 11 and 12, among which it is arranged, slide on each other and to make, furthermore, a high airtight and insulation to water, in addition to a good acoustic insulation.
- sealing member 20 is shown in figure 4 .
- support surface 12 is arranged on a profile 30 slidingly coupled to a profile 40.
- the latter has a guiding head 45 at which the sealing surface 11 is made.
- profile 30 comprises a housing 35 in which the guiding head 45 slidingly engages.
- the sealing member 20 is arranged between surfaces 11 and 12. It can have, for example, a mushroom-like shape, as shown in the cross sectional view of figure 5 , for being equipped with a base 27 engaged at a groove 31 of profile 30, and a head 24 protruding from the support surface 11 and coupled to the layer of low friction coefficient material 22.
- sealing member 20 can be connected to the guiding head 45 by a adhesive layer 23 ( figure 9 ).
- the support surface 11 is made on the guiding head 45, and sealing surface 12 defines the housing 35 of the profile 30 coupled slidingly with head 45.
- a support surface 11 can be made at a first panel 51, for example of a closet 50, and the other sealing surface 12 at a second panel 52 that slides with respect to panel 51.
- the panels 51 and 52 for example can be arranged sliding between a couple of uprights 53 and 54 of closet 50. Even in this case the use of the sealing member 20 reduces the friction between the two panels 51 and 52 when they slide relative to each other.
