Definitions

  • the present invention generally relates to the technical field of accessories for shading curtains, and it particularly relates to an edge pad to be mounted on the slats of a venetian blind.
  • the invention also relates to a kit for transporting and storing one or more of such pads, as well as a slat which includes an edge pad.
  • Venetian blinds which consist of a plurality of slats mutually movable between an inoperative position, in which they are mutually packed, and an operative position, in which they are mutually spaced apart, are known.
  • An example of such venetian blinds is known from the Patent CH384185A .
  • the slats are generally provided with pads at one of the edges, so as to absorb the vibrations between the adjacent slats for example due to rushes of wind or impacts. More precisely, each slat is provided with an edge longitudinal slot into which the pad is inserted.
  • Such pads generally include a portion for coupling to the longitudinal slot of the slat and a working portion made of soft material protruding from the slot to remain facing the edge portion of the slat and carry out the function mentioned above.
  • the displacement between the inoperative and operative positions mentioned above includes a step for mutual sliding between two adjacent slats, wherein the edge portion of a slat slides for a predetermined section on the surface of the slat of the adjacent edge.
  • German utility model DE8317650U1 discloses a slat which rotates without translating. When closed, the slats are in contact at the relative pad.
  • An object of the present invention is to at least partly overcome the aforementioned drawbacks, by providing an edge pad for a slat of a venetian blind that is highly efficient and cost-effective.
  • Another object of the invention is to provide an edge pad for a slat of a venetian blind that limits to the maximum or entirely eliminates the vibrations between the slats upon the sliding between them.
  • Another object of the present invention is to provide an edge pad for a slat of a venetian blind that is simple and cost-effective to produce.
  • Another object of the present invention is to provide a kit that allows a simple, practical and cost-effective displacement, storage and transportation of edge pads for venetian blinds.
  • an edge pad for a slat of a venetian blind and by a transportation and storage kit as described, illustrated and/or claimed herein.
  • an edge pad 1 for the slats L of a venetian blind T is an edge pad 1 for the slats L of a venetian blind T.
  • the venetian blind T consists of a plurality of slats L, possibly made of metal material, which can be displaced between an inoperative position, for example shown in FIG. 1 , and several operative positions, for example shown in FIGS. 2, 3A and 3B .
  • one or more slats are spaced from the previous and/or subsequent slat, so that the front and rear edge areas B', B" of each spaced slat are distal from the corresponding front and rear edge areas B', B" of the previous and/or subsequent slat.
  • FIGS. 3A and 3B define the fully open configuration and with the maximum overall dimensions of the venetian blind T, while FIG. 2 defines an intermediate configuration between the fully closed and open configuration.
  • the venetian blind T upon opening the venetian blind T, the latter passes from the inoperative position ( FIG. 1 ) in which it is fully closed to the intermediate operative position of FIG. 2 , in which the edge area B' of the slat L slides for a predetermined section on the surface S of the adjacent slat L'.
  • the sliding direction of the edge area B' of the slat L may be substantially perpendicular to the longitudinal axis X defined by the pad 1, better explained hereinafter.
  • the edge pad 1 may have an extended shape along an axis X, and be suitable to be mounted in a longitudinal slot C arranged at the edge portions B' and/or B", and it may comprise a portion 10 for coupling for the longitudinal slot C, a working portion 20 and a connection position 30 interposed between them.
  • a portion 10 for coupling for the longitudinal slot C a working portion 20 and a connection position 30 interposed between them.
  • the latte may be absent without departing from the scope of protection of the attached claims.
  • the coupling portion 10 may preferably be counter-shaped with respect to the longitudinal slot C.
  • the working portion 20 may protrude from the longitudinal slot C to remain facing the edge portion B of the slat L, so as to slide on the surface S upon opening and / or closing of the venetian blind T and absorb the possible impact of the slat L with the previous and/or subsequent slats, for example due to rushes of wind or impacts, and/or act as soundproof means and/or maximise the shading effect of the venetian blind T.
  • the working portion 20 may consist of a first zone 21 e and a second zone 22, whose functions will be clearer hereinafter.
  • the zones 21, 22 may be mutually positioned between each other and configured so that only the first zone 21 comes into contact with the surface S of the adjacent slat L' upon the sliding mentioned above.
  • the zones 21, 22 may be mutually positioned between each other and configured so that upon closing the venetian blind T, the second zone 22 remains facing the adjacent slat L' only after the sliding of the first zone 21 on the surface S of the latter.
  • the first zone 21 has the function of facilitating the sliding of the edge area B' of the slat L on the surface S of the adjacent slat L', while the second zone 22 has the function of absorbing the possible impact of the slat L with the previous and/or subsequent slats.
  • the second zone 22 may also act as soundproof means and/or maximise the shading effect of the venetian blind T. To this end, the second zone 22 may at least partially come into contact with the previous and/or subsequent slat.
  • the working portion 20 may consist of a substantially curved laminar element in which the first zone 21 is the front and the second zone 22 is rear.
  • the working portion 20 may have a first end edge 23 operatively connected with the coupling portion 10 through the connection portion 30 and a second vacant opposite end edge 24.
  • the first zone 21 may include the vacant edge 24, while the second zone 22 may include the edge 23 connected with the coupling portion 10.
  • the zones 21, 22 may have respective edges 25, 26 opposite to the edges 24, 23 in contact with each other, so that the zones 21, 22 are consecutive to each other.
  • the portions 10, 20 and, if present, 30 may be obtained by means of suitable materials.
  • the coupling portion 10 may be made of a thermoplastic polymeric material. If present, the connection portion 30 may be monolithic with the coupling portion 10 and made of the same material or different material.
  • the working portion 20 may be made of at least two materials.
  • the first zone 21 may be made of an anti-friction polymeric material, preferably a thermoplastic polymeric material may identical or not identical to that of the coupling portion 10 and, if need be, to that of the connection portion 30.
  • the second zone 22 may be made of an elastomeric or thermoplastic elastomeric material.
  • the material of the first zone 21 and possibly of the coupling portion 10 may preferably be a polyolefin, for example polypropylene, while the material of the second zone 22 may be a thermoplastic elastomer compatible therewith, for example a TPE-O.
  • appendages 28 may be made of the same material as the zone 22 or of a different elastomeric or thermoplastic elastomeric material.
  • appendages 28 may extend from the second zone 22 in any direction, for example below and/or above, without departing from the scope of protection of the attached claims.
  • the materials mentioned above may be coextruded, so as to obtain the working portion 20 through a single extrusion step.
  • the hardness of the anti-friction polymeric material of the first zone 21 may be greater than that of the elastomeric or thermoplastic elastomeric material of the second zone 22.
  • the elastomeric or thermoplastic elastomeric material of the second zone 22 may have a Shore A hardness comprised between 65 ShA and 90 ShA, while the anti-friction polymeric material of the first zone 21 may have a Shore D hardness comprised between 25 ShD and 60 ShD.
  • the hardness may be determined according to the known DIN EN ISO 868 standard.
  • the first zone 21 will facilitate the sliding of the edge area B' of the slat L on the surface S of the adjacent slat L', as shown in FIG. 6A , while the second zone 22 will absorb the possible impact of the slat L with the previous and/or subsequent slats, as shown in FIG. 6B .
  • the latter may come into contact with the surface S of the adjacent slat L' towards the end of the sliding of the first zone 21 thereon, so as to act as soundproof means and/or the shading effect of the venetian blind T.
  • At the first zone 21 there may be provided one or more projections extending outwards so as to come into contact with the surface S of the adjacent slat L' after the sliding step, so as to keep the slats L, L' spaced from each other.
  • kit 100 shown in FIG. 8 may be used in order to transport and store the edge pads 1.
  • Such kit may essentially include a plurality of reels 110 inserted into a rack 120, which is provided with removable stacking means 130, 131 of one or more identical racks.
  • One or more edge pads 1 with predetermined length, to be cut whenever required by the manufacturer of the venetian blinds T, may be wound around each reel 110.
  • the rack 120 may consist of metal tubular elements, may be suitable to be loaded on a truck and, once unloaded, suitable to be stacked with other similar.
  • the rack 120 may include one or more cradles 140 suitable to house a plurality of reels 110 arranged adjacent to each other along the axis thereof.
  • Each cradle 140 may define a storage plane designed to remain substantially parallel to axis of the reels 110 arranged side by side.
  • the storage plane may be defined by at least two profiles 141, 142, which may possibly be triangular-shaped in plan view.
  • the particular configuration of the rack 120 will allow to keep the reels in vertical position, that is with horizontal axis, and avoid stacking them with the vertical axis.
  • the rack 120 and the one or more reels 110 may be used for storing and transporting any pad, not necessarily the pad 1 having the characteristics described above, or of any elongated element.
