Abstract
Description
- The present invention generally finds application in the field of heat and sound insulating devices for doors and windows, and particularly relates to a seal for door or window leaves.
- The invention also relates to a sealing device for door and window leaves which incorporates such seal.
- Seals are known to be used in door and window leaves for closing off any gap occurring between the leaf and either the floor or the threshold.
- Particularly, insulating seals are generally adapted to be applied to the upper and/or lower edges of the leaf.
- Thus, for example, these seals are typically applied to the lower edges of the doors to prevent the passage of air through the gap and enhance heat and sound insulation in the environment.
- Furthermore, insulating seals are often designed to interact with appropriate actuator means which are adapted to cause vertical translation thereof, as the leaf is opened and closed.
- Particularly, these actuator means keep the seal away from the floor as the leaf is opened and cause the seal to contact the floor when the leaf is closed.
- A strong need in the art is that of providing seals for door and window leaves that ensure high insulation even when they have to close off gaps with irregular or indented profiles.
- For this purpose, seals for door or window leaves have been provided, whose sealing edge is specially designed to fit the irregularities in the floor or the threshold.
- For example,
EP1905938 discloses an insulating seal for doors comprising a rail that is designed to fit into a longitudinal channel formed in the lower edge of the door, and a longitudinal sealing member held within the rail, and adapted to close off the gap between the floor and the door edge. - Particularly, the sealing member is flexible and has one or more continuous downwardly extending lip projections with respective free end edges designed to contact the floor or the threshold.
- The relatively small thickness of the lip projections allows the end edge to fit the profile of the floor or the threshold even when the latter are uneven or irregular.
- While this arrangement considerably improves the sealing action of the seal, it still suffers from certain drawbacks.
- Particularly, a first drawback of this arrangement is that the continuous end edge of the lip projection cannot fully conform to the profile of any type of floor or threshold.
- Thus, the sealing effect of the lip projection is considerably reduced when the floor profiles to be insulated comprise tile joints extending to great lengths, of having particularly deep concavities or convexities.
- A further drawback of this arrangement is that extended use of the seal may lead to a permanent alteration of the shape of the lip projections.
- This occurs because the end edge of the latter tends to conform to the profile of the irregularities of the floor or the threshold, thereby affecting the sealing action of the seal.
- Also, not last serious drawback of this arrangement is that the sealing member can be hardly removed from the rail, whereby no quick replacement thereof is possible, in case of wear or damage to the lip projections.
- The object of the present invention is to obviate the above drawbacks, by providing a seal for door and window leaves that is highly efficient and relatively cost-effective.
- A particular object of the present invention is to provide a seal for door and window leaves that has high insulation and soundproofing properties irrespective of floor or threshold conformations.
- A further object of the present invention is to provide a seal for door and window leaves that provides high and substantially consistent efficiency.
- Another object of the present invention is to provide a seal for door and window leaves that is easily replaceable when worn or damaged.
- These and other objects, as better explained hereinafter, are fulfilled by a seal for doors and windows, particularly for hinged doors, sliding doors, windows or frames, comprising a profile made of a flexible material, which is designed to be applied to the lower edge of a door or window leaf, said profile having an elongate connecting portion with a longitudinal axis from which at least one lower lip projection extends to interact with the floor or the threshold of the leaf.
- The seal is characterized in that said at least one lip projection has a plurality of substantially transverse cuts uniformly arranged along the entire longitudinal extent of the projection, and defining a plurality of independent flexible segments, which are adapted to allow the seal to fit the irregularities of the floor or the threshold with low friction.
- These features will provide a weather and sound proofing seal for door and window leaves that allows insulation of gaps formed with irregular or uneven floors or thresholds and maintains a high degree of insulation even after a relatively great number of cycles of use.
- In a further aspect, the invention relates to a sealing device for door and window leaves as defined in
claim 10. - Advantageous embodiments of the invention are obtained in accordance with the dependent claims.
- Further features and advantages of the invention will be more apparent upon reading of the detailed description of a few preferred, non-exclusive embodiments of a seal and a sealing device for door and window seals according to the invention, which is described as a non-limiting example with the help of the annexed drawings, in which:

- Namely, the seal 1 may be advantageously applied to an end edge B of a leaf A of a door or window S, to provide a sealing effect at a gap F with the floor P or a threshold that may have shape irregularities, due to the presence of joints K between tiles T, or flatness or tilt errors.
- Furthermore, the seal 1 may be used to provide insulation and lateral protection in sliding doors Z or may be alternatively used to provide a sealing action on windows or other frames.

lip projection 4 has a plurality of substantiallytransverse cuts 5 uniformly arranged along the entirelongitudinal extent 14 of theprojection 4, thereby defining a plurality ofindependent lip segments 6, which are adapted to impart greater flexibility to the seal 1 and to allow it to fit the irregularities of the floor P or the threshold with low friction. - Due to this feature, each
segment 6 may be elastically deformed in the vertical direction to fit the local profile of the floor P or the threshold, independently of the other profiles. Conveniently, thelip projections 4 may have equallongitudinal extents 14. - The
cuts 5, as best shown in the figures, may be substantially vertical and perpendicular to the longitudinal axis L. - Furthermore, the
cuts 5 may be longitudinally arranged with a substantially constant pitch p, to definesegments 6 having substantially equal longitudinal extents. - For example, the
cuts 5 may be arranged with a pitch p ranging from 1 mm to 10 mm, preferably of about 3 mm. - Conveniently, as best shown in the figures, the
cuts 5 may have an extent w corresponding to part of the maximum height h of thelip projection 4 and theflexible segments 6 may be connected together at the remaining part of the maximum height h of at least onelip projection 4. - Furthermore, cuts 5 may have equal transverse extents w.

cuts 5 may be arranged with a variable pitch p and have different transverse extents w to definesegments 6 of different sizes. - Conveniently, as best shown in
FIGS. 4 and 5 , theelongate body 3 may comprise a centraltubular body 7 whosebottom face 8 is designed to contact the floor P or the threshold. - Also, the seal 1 may have a pair of lip projections, referenced 4, 4' in the figures, extending downwards from the sides of the central
tubular body 7. - Each
lip projection 4, 4' may have a respective plurality ofindependent segments 6 which are designed to contact the floor P or threshold. - Thus, the seal 1 will provide an overall sealing action, resulting from the superimposed sealing actions of the
tubular body 7 and each of thelip projections 4, 4' on the floor P or threshold. - Advantageously, the
tubular body 7 may have a plurality of additional substantially transverse cuts 9, not shown, similar to those of thelip projections 4, 4'. - Cuts 9 are adapted to define a plurality of independent longitudinal
tubular portions 10 in thetubular body 7, for helping the tubular body to fit the irregularities of the floor P or the threshold. - Particularly, the
tubular portions 10 may undergo differentiated vertical compression to fit the irregularities and inclinations in the floor P or the threshold. - Conveniently, as best shown in
FIGS. 2 and 3 , the seal 1 may comprise a plurality of substantiallyparallel lip projections 4, extending downwards from the connectingportion 3. - The
lip projections 4 may be composed of respective pluralities oflip segments 6, adapted to contact the floor P or threshold. - Here, the overall sealing action of the seal 1 results from the sum of the sealing actions of the
individual lip projections 4 on the floor P or threshold. - Conveniently, as shown in
FIG. 7 , thelip projections 4 may have differentiated heights f for selective thereof with the floor P or threshold, upon downward translation of the seal 1, occurring as the leaf A is being closed. - Conveniently, as shown in
FIGS 8a to 9b , thecorresponding cuts 5 of theindividual lip projections 4 may lie on substantially vertical and longitudinally staggered planes n. - Namely, as shown in
FIG. 8a , thecuts 5 may lie on planes n perpendicular to the longitudinal axis L. - Such arrangement of the cuts, as schematically shown in
FIG. 8b , provides respective sequences ofsegments 13 aligned in respective horizontal directions X, perpendicular to the longitudinal axis L. - Alternatively, as shown in
FIG. 9a , thecuts 5 may lie on planes π perpendicular to the longitudinal axis L, such that thelip segments 6 of theindividual projections 4 may be arranged in staggered relationship to respective horizontal directions X perpendicular to the longitudinal axis L, as schematically shown inFIG. 9b . - Furthermore, as shown in
FIG. 10a , thecuts 5 may lie on planes ψ that are substantially vertical and inclined to the longitudinal axis L, at a predetermined inclination angle α. - Such arrangement of the
cuts 5, as schematically shown inFIG. 10b , providesrespective sequences 13 ofsegments 6 aligned in respective directions Y inclined to the longitudinal axis L at said inclination angle α. - In a further aspect, the invention also relates to a
sealing device 14 for leaves A of doors and windows S, as best shown inFIGS. 11 and 12 , comprising anelongate support 15, which is adapted to fit into a channel C formed in the lower edge B of the leaf A. - The

longitudinal lip projections 4 in substantially uniformly staggered arrangement, as shown inFIG. 11 , or may comprise atubular body 7 and a pair oflop projections 4, 4', as shown inFIG. 12 . - Conveniently, the
elongate support 15 may be substantially U-shaped, to define aninner housing 16 for the seal 1. - The latter comprises a substantially longitudinal
elongate connecting portion 3, which has a pair oftransverse arms ends inner wall 21 of thecompartment 16 and easier friction fit of the seal 1 therewith. - Conveniently, the
device 14 may comprise actuator means 22, which are located within thesupport 15 and act upon the seal 1 to cause vertical translation t thereof, and compression of thelip projection 4 against the floor P or threshold. - Particularly, the actuator means 22 may be designed to cause vertical translation t of the seal from an inoperative position at least partially retracted in the
compartment 16 to an operative position at least partially projecting from thecompartment 16. - In the inoperative position the

inner edge 25 of theinterface element 23 or with theupper wall 26 of the seal to cause translation t thereof between the inoperative position and the operating position. - The seal 1 may be stably connected with the
interface element 23 through appropriate mutual coupling means 27. - Particularly, the mutual coupling means 27 may be of interlocking type and may comprise a
first coupling member 28 formed in the connectingportion 3 of the seal 1 and asecond coupling member 29, whose shape is substantially complementary to that of thefirst coupling member 28, formed in theouter edge 24 of theinterface element 23. - The presence of interlocking means 27 will afford very quick and simple removal or replacement of the seal 1 of the
device 14. - Conveniently, as best shown in
FIG. 13 , at least one seal of the invention, preferably a pair of seals 1, 1' may be applied to the side leaves A, A' of a sliding door Z for lateral protection thereof and for providing weather proofing and improving heat and sound insulation in the environment. - Particularly, the seals 1, 1' may have a specially shaped connecting
portion 3, 3', which is designed to slidably fit into dedicated channels C, C' formed on the mutually facing edges of the leaves A, A'. - Conveniently, the
lip portions 4 of the seals 1, 1' may extend in longitudinal directions L, L' substantially orthogonal to the sliding direction R of the door Z. - The above disclosure clearly shows that the invention fulfills the intended objects and particularly meets the requirement of providing a seal and a sealing device affording a high weatherproofing effect regardless of the type of floor or threshold.
- The seal and sealing device of this invention are susceptible to a number of changes or variants, within the inventive concept disclosed in the annexed claims. All the details thereof may be replaced by other technically equivalent parts, and the materials may vary depending on different needs, without departure from the scope of the invention.
- While the seal and the device have been described with particular reference to the accompanying figures, the numerals are only used for the sake of a better intelligibility of the invention and shall not be intended to limit the claimed scope in any manner.
