Definitions
- the invention relates to occultation or separation devices for interior design.
- the invention thus relates for example to devices implementing at least one movable panel, for example a curtain, a vertical blind type "awning”, a vertical blind type “winder”, a blind band vertical type “Californian blind”, or a sliding panel on the rails fixed to the ceiling, wall or panel type "Japanese panel”, the panels included in these devices are generally free of any fixing in the lower part.
- Such panels are used to dress openings (windows, bay windows), to modulate spaces by being used as separating elements in a room, also to close storage spaces.
- the panels Due to their positioning, especially when used in front of bays or in part separation, the panels are very sensitive to drafts, be they curtains, boat blinds, roller blinds or Californian blinds, or even sliding panels, and especially if these panels have significant dimensions.
- each panel behaves like a sail and tends to "fly" and therefore to be printed movements that are often of such magnitude that, on the one hand, the continuity of the textile wall formed by the panel or panels is broken and that, on the other hand, the free end of the panel can be caused to hit fragile objects arranged in its vicinity, such as fixtures or dishes, and damage them.
- each panel with a weight bar in the lower portion of the panel, in order to produce on the panel a vertical traction force intended to oppose the horizontal thrust force. produced by the air flow on the panel.
- the invention particularly aims to overcome the disadvantages of the prior art.
- an object of the invention is to allow better prevention of inadvertent movements of panels due to drafts. 4. Presentation of the invention
- the invention relates to a device for concealing an embrasure including at least one movable panel capable of being placed in front of the doorway, characterized in that it also includes at least a ballast element disposed in the vicinity of a center of vane force of said panel.
- the inventors have adopted a new and inventive approach of transposing to the technical field of curtains and blinds elements of theory peculiar to the field of boating.
- the inventors have devised a theory according to which the panel could be likened to a sail having a center of sailing thrust.
- the term "thrust center” as used in the description refers to the point of application of drafts on the panel. In the field of sailing, the position of this point is not fixed and may depend on several variables, including the shape of the sail, its stability over time, the relative orientation of the wind, or the layout of the points of bet under tension of the sail.
- the position of the center of vault thrust is fixed and corresponds to that of the center of gravity of the movable panel.
- the center of vane force of a movable panel of rectangular shape is precisely positioned in the center of the panel.
- the invention is however not limited to a particular form of panel.
- a person skilled in the art will understand that according to other embodiments of the invention, implementing a panel of different shape (trapezoidal, triangular, etc.), the center of the vane force is positioned at the center of gravity of the sign.
- the work of the inventors has made it possible to show that a weighting element is near the center of velocity thrust, and more the effects produced by this means of neutralization of the thrust are important.
- the arrangement of the ballast element in the vicinity of the center of veiling force thus makes it possible to produce a significantly greater stabilizing effect than in the case where this element is removed from this point.
- the new approach adopted by the inventors thus makes it possible to maximize the efficiency of the weighting elements.
- the total volume of ballast elements necessary for the stabilization of the panel can therefore be reduced, taking into account the more judicious positioning of the latter, which has the additional advantage of making the panel easier to maneuver in sliding and / or in lifting.
- the panel is provided with at least two weighting elements, it will be advantageous to arrange them symmetrically vis-à-vis a center of vane force of said panel, so that the resultant effects produced by these symmetrical weighting elements are located in the immediate vicinity of the center of sailing force and thus produce a maximum effect.
- immediate proximity refers in metric terms to a distance of less than 0.05m, preferably less than 0.025m, preferably less than 0.01m.
- the weighting elements can take different forms and be made in different ways.
- at least one weighting element is made in a modular form allowing adjustment of the weight of said weighting element.
- the user of the device will be able to define the configuration of the weighting of the panel (s) as a function of the conditions of use of the concealment device, and to carry out by himself or an installer configuration.
- a modular ballast element may for example take the form of a plurality of ballast bars adapted to be slid into contiguous tunnels arranged in the panel, the number of bars actually slid into the tunnels determining the weight of the ballast element thus obtained.
- a modular ballast element will be formed by at least one pair of straight or corrugated bars, which will be carried out primarily in metals or alloys of high density, such as steel, brass, or secondarily aluminum alloy or in woods preferably with high density, which bars are intended to be arranged on either side of the panel and to be secured to one another, for example by means of magnets or screwing elements, or made integral with the panel itself, for example by gluing, the implementation of magnets being especially interesting because it offers the user a great flexibility of configuration .
- Such a mode of implementation is particularly advantageous for at least two titles.
- it offers a certain flexibility to the user or to an installer of the device as to where he has the ballast element, since no prior arrangement is required within the panel itself, and in particular no tunnel or hem, which also allows to limit the cost price of the panel.
- this mode of implementation provides an increased aesthetic pleasure, because, the bars of each pair being arranged on either side of the panel, the external appearance of this panel will be identical to its internal appearance, while the outer appearance of the panel is usually noticeably less neat than its interior appearance.
- At least one ballast element forms a strip or bar made of a material heavier than the material of the panel.
- said band will preferably extend, but not necessarily, in a substantially horizontal direction, in order to ensure in a simple manner a symmetry vis-à-vis the center of thrust.
- Such a weighting band may be rectilinear, but it may advantageously have a wavy shape.
- the weighting band has in the vertical direction a footprint on the panel which is larger than the width of the strip itself, which confers additional rigidity to the panel thus equipped. Moreover, at equal lengths, a band having a wavy shape will be heavier and occupy a larger overlap surface than a straight strip and thus produce a greater ballasting effect.
- the ballast strip is made of a flexible material.
- At least one weighting element is constituted by a row of integral weight of the panel.
- At least two adjacent weights are suspended from the panel by a flexible link, said adjacent suspended weights each including a magnetic element having a polarity opposite to that of the magnetic element of the adjacent weight , each link having a length greater than half the distance between the two adjacent weights.
- the panel is provided with at least one opening intended to allow an air passage through the panel from one side to another side of said panel.
- the opening may be unique, thus forming a kind of chimney, in which case it will advantageously be covered by a piece of fabric connected to the panel by fasteners to preserve the overall opacity of the panel.
- This piece of fabric may be made of the same material as that of the panel, but it may also be made of a material having a texture and / or a different color, in order to produce a particular aesthetic effect, even a weighting effect if it is made of a heavier material than that which composes the panel.
- a single aperture will preferably be disposed in the vicinity of the vane push center of the panel.
- the panel may comprise a plurality of openings forming at least one substantially horizontal row.
- the panel is provided with a ballast element consisting of a strip made of a material heavier than the material of the panel
- said strip advantageously include openings intended to allow air to pass through the panel from one side to another side of said panel.
- each opening may be surrounded by an eyelet made of a heavier material than the material of the panel.
- the openings incorporate in themselves weighting means and thus produce two complementary technical neutralization effects.
- at least two adjacent eyelets serve as attachments to flexible links each having a length greater than half the distance separating said adjacent openings.
- these will preferably be arranged symmetrically vis-à-vis a horizontal line on which is the center of veiling thrust, the openings forming these rows being they themselves arranged symmetrically vis-à-vis a vertical line on which is the center of thrust, so as to obtain a symmetry in both dimensions of the panel. 5.
