Abstract
There is described a guide that allows sliding of foldable/unfoldable horizontal screens guaranteeing the rigidity required.
Description
- The present invention relates to the field of sliding screens.
- For closing doors or window there are often used screens consisting essentially of a frame (which is fitted to the opening to be protected by means of appropriate fastening means, optionally removable) and of a curtain capable of sliding from one side to the other of the frame through appropriate tension and return means present in or on this frame, closing the opening.
- A typical example of screens of this type are insect screens in which the curtain consists of a fabric (or similar material) with a very dense weave which is thus capable of preventing insects from entering through the door or window to which the screen is fitted.
- Sliding of the curtain can take place either vertically (from the top downward and vice versa) or horizontally (from right to left or vice versa), normally the curtain is pleated in a manner such as to minimize the overall dimension in the closing step. Recently, "foldable/unfoldable" horizontal sliding screens of the aforesaid type have become available, in which the frame consists of two parallel uprights joined to each other through two flexible rails which in closed position are housed inside one of the two uprights positioned side by side, while in open position they consist of the other two sides of the frame; the curtain is connected to the uprights with two of its parallel sides while the other two sides can slide in the groove of the rails.
- Said flexible rails consist of a plurality of rigid bodies placed in sequence one behind the other and in which one rigid body partially overlaps the adjacent body; said rigid bodies are capable of rotating partially with respect to one another, being endowed of a pin placed in the front part capable of engaging in a respective slot arranged in the back part of each rigid body in a manner such as to allow said partial upward or downward rotation of two adjacent bodies (see, for example,
EP 999335 - This solution is very practical as it permits the curtain to be kept correctly tensioned without requiring to install fixed guides and/or rails, which would get in the way when the screen is retracted; however, they have the drawback of not being sufficiently rigid and therefore are not completely satisfactory.
- The present invention relates to a horizontally sliding screen in which the sliding guide remains rigid during the step to open or close the screen.

-
Fig. 1 schematically shows a guide according to the invention. -
Fig. 2 shows in particular a unit constituting the guide according toFig. 1 . -
Fig. 3 shows the operation of freeing the units forming the guide. - The present invention overcomes the aforesaid problems through a sliding guide for horizontal sliding screens consisting of a plurality of rigid bodies presenting engaging means that permit reciprocal engaging and locking.
- As can be seen in
Fig. 1 , a guide according to the invention consists of a plurality of rigid bodies 11 which present an engaging means that allows at least partial reciprocal rotation thereof, and a second engaging means which, when active, blocks any movement between said rigid bodies. - Said rigid bodies (see
Fig. 2 ) consist of twoparallel walls 14, the front and back of which is essentially round, saidwalls 14 being joined between each other by a plane 15 perpendicular to said walls. - Each of the two
walls 14 is formed by twosurfaces 16, 17 joined between each other by a concave step 18; therefore, two portions of surface will be nearer to each other and two more removed from each other (according to the height of the step 18). - The surfaces 16 (the ones nearer to each other) present a
circular bulge 19 and one of said surfaces 16 also has aportion 20 capable of elastically moving towards the inside, under the action of a suitable pushing means, and endowed of apin 21 placed ahead the circular bulge (19). - The surfaces 17 (those more removed from each other) present a
circular hole 22 capable of engaging pivoting with thecircular bulge 19 of the adjacent rigid body 11, and thesurface 17 placed on the same side of the surface 16 presenting thepin 21 also has asecond hole 23 capable of engaging in a fixed manner with thepin 21 of the adjacent rigid body and therefore capable of preventing (when inserted) any movement between the rigid bodies; moreover, thissurface 17 also presents an external wing 17' capable of sliding for a length along the step 18. The plane 15 of each rigid body 11 presents astep 24, placed in correspondence of the step 18, on which rests the plane 15 of the adjacent rigid body 11. - As can be seen from
Fig. 1 , the rigid bodies 11 thus interlock in each other reciprocally engaging thebulges 19 and thepins 21 of the one respectively with theholes - This forms a rigid chain which, when in tension, cannot bend either upwards or downwards and which therefore forms an ideal rail for vertical support of the curtain of the screen. Said chain can instead bend when the
engaging pin 21 is made free, permitting partial reciprocal rotation of two adjacentrigid bodies 21 around thebulges 19. - For this purpose, on the frame that houses and encloses the closed screen, close to the point of entrance/exit of the chain, a
fixed thickness 25 will be present, capable of acting laterally on thepin 21, making it free from the correspondingengaging hole 23, due to the elasticity of theportion 20 with respect to the rest of the surface 16, and permitting bending of the chain; once the pushing action of thethickness 25 ceases, theportion 20 will return to the initial position, engaging thepin 21 once again with thecorresponding hole 23. - It is noted in this regard that the presence of the step 18 and of the wing 17' permits rotation of the rigid bodies in only one direction and therefore bending of the chain in its entirety only to one side which offers a further guarantee of rigidity for the screen.
- Operation of the guide according to the invention is self evident: by pulling the free upright of the screen towards the outside (or pushing it towards the inside), the chain can respectively exit from or enter the upright that houses it due to the disengaging of the
thickness 25 from the various rigid bodies 11 which can thus rotate permitting bending of the chain at the point of entrance/exit of the upright that houses it; once the rigid bodies 11 have moved past the point of thethickness 25 they can once again engage with each other, guaranteeing the chain the rigidity required.
