SUNSHADE BLADE

Description

[0001] The present invention relates to a sunshade blade in a system of constraint and articulation of the blades.

[0002] Sunshades with packable and adjustable blades are known, the ends of which are connected to the blade holders of the movement mechanisms inserted inside vertical lateral guides.

[0003] Said blade holders consist of a C-shaped support whose folded ends are inserted into the hinges of articulation of the blades, said C-shaped supports being integral with a pin whose other end is provided with a plate affected by a substantially rectangular hole.

[0004] However, these known systems for attaching the blade holders to the blades have the drawback of a large bulk in the thickness of the blades, so that the total packing of the blades involves a high loss of light with large-sized sunshades (about 39 cm for compartments with a height of 2.7 m of inter-plane).

[0005] WO 2016103123 A1 describes sunshade apparatus (1) comprising at least one slat having a guide integral therewith and extending along a longitudinal direction of the slat; at least one movement element configured to be coupled to one end of the slat; a locking element slidably coupled to the guide of the slat, to be movable along the longitudinal direction between a deactivated position, where it does not interfere with the movement element , and an active position, where it is at least partly superposed on the movement element to lock it relative to the slat; an elastic structure for applying a force perpendicular to a contact surface between the slat and the movement element when the locking element is at the active position.

[0006] The object of the invention is to eliminate these drawbacks and to provide a fastening system for the blade holders which has a reduced thickness so as to be able to reduce the overall dimensions of the packed blades of the sunshade.

[0007] This object is achieved according to the invention with a system of constraint and articulation of the blades in sunshade with packable blades as described in claim 1.

[0008] The present invention is further clarified hereinafter in a preferred embodiment shown purely by way of example and non-limiting with reference to the attached drawing tables in which:

[0009] As can be seen from the figures, the constraint and articulation system of the sunshade blades in packable blades substantially comprises a plurality of elements 2, 2' in zamak to form two hinges 4.

[0010] In particular, the elements 2 are articulated by a brass eyelet 6, while the elements 2' are articulated to each other by means of steel or plastic pegs 8 which also engage in a hole 10 provided at the end of a wing 12 of a zamak blade holder 14 and in a sleeve 16 present at the other end of the wing 18 of the blade holder 14.

[0011] The blade holder 14 has a cross shape and is formed by a cylindrical sleeve 20 to which a substantially quadrangular plate 22 is integral with a slot 24 and two reliefs 26.

[0012] The system comprises a blade 28 in aluminum with a thickness between 0.7 mm and 1.20 mm, formed by a central body 30 slightly curved which extends into two lateral fins 32 folded towards the bottom and rolled up at the ends 34.

[0013] The central body 30 presents a slot 36 whose dimensions correspond to the dimensions of the slot 24 and two further slots 38 whose dimensions correspond to those of the reliefs 26.

[0014] The elements 2, 2', the blades holder 14, the plate 22, the central body 30 and the clip 42 have a height of less than 7 mm.

[0015] The connection between the central body 30 of the blade 28 and the blade holder 16 is obtained by inserting the reliefs 26 of the central body 30 in the slots 38 of the blade 28 and subsequently inserting a clip 40 with curved appendages 42 which snap into undercut slots 36. A slide 50 made of thermoplastic material sliding along a vertical slot 52 provided is snapped onto the cylindrical sleeve 20 in a cylindrical seat 48 in the case 54 housing the hinge. The slide 50 has, in correspondence with two surfaces, two vertical appendages 56 facing downwards which, when the runner is superimposed in contact with the lower runner, is engaged in corresponding seats 58 of the underlying runner.

[0016] From what has been said it is clear that the constraint and articulation system of the blades in packable blade holders with folding blades allows, thanks to the materials used and the heights of the elements 2, 2', blade holders 14, plate 22, central body 30 and clips 42 which have height of less than 7 mm to reduce the overall dimensions of the packed blades of the sunshade.

[0017] Moreover, thanks to the presence of the two reliefs 26 which are inserted in the two slots 38, the constraint system has a greater torsional rigidity.
