Definitions

• This invention relates to a sunshade apparatus and to a method of assembling a sunshade slat.
• shade apparatus may identify a Venetian blind, that is to say, an apparatus provided with horizontal slats which can be oriented horizontally. Venetian blinds can be retracted by lifting and stacking the slats.
• Sunshade apparatuses which are provided with a plurality of sunshade slats which, in use, are designed to screen a room from sunlight so as to allow controlling the amount of light entering the room where the sunshade apparatus is installed.
• the sunshade slats are movable simultaneously by means of a slat connecting mechanism forming part of the sunshade apparatus.
• the connecting mechanism comprises a plurality of slat movement elements each of which is, in use, integrally coupled to one end of a slat.
• These sunshade apparatuses are also provided with a pair of opposite lateral guides which house and guide the movement elements: more specifically, these apparatuses comprise a first lateral guide, with which first movement elements are associated, and a second lateral guide, opposite to the first, with which second movement elements are associated.
• each slat is thus fixed, at a first end of it, to a first movement element which is slidably associated with the first guide and, at a second end of it, to a second movement element which is slidably associated with the second guide.
• each slat is bilaterally coupled to the connecting mechanism so that it can be moved and oriented.
• a need which is particularly strongly felt in the sector concerned is that of having a sunshade slat which can be fixed very quickly and easily to the elements of the connecting mechanism and which, at the same time, allows the connecting mechanism to guarantee a particularly high degree of robustness for the apparatus.
• a sunshade slat comprises a guide which is integral with the slat and which extends in the longitudinal direction thereof.
• the system by which the slat is connected to the connecting mechanism comprises a first locking element by which the slat is locked to the first movement element and a second locking element by which the slat is locked to the second movement element.
• the first locking element and the second locking element are slidably coupled to the guide so as to be movable along the longitudinal direction between a position of non-interference with the respective movement element and a coupling position where it is locked to the respective movement element.
• This connecting system although it allows connecting the slats quickly by means of a relatively simple solution, is not flexible. In effect, the locking elements of this solution cannot be coupled or adapted to be coupled to different types of movement elements and are not therefore applicable to sunshade apparatuses of all kinds (that is, to sunshade apparatuses having movement elements of a different kind).
• this fixing method does not guarantee a very good degree of robustness, in use, thus limiting the reliability of the system.
• the slat is subject to vibrations which make the sunshade apparatus noisy, for example in the case of wind or during opening and closing of the sunshade.
• sunshade apparatuses and related systems for locking the slats to the slat movement elements are provided in the following patent documents: US4444242A, WO201 1/099078A1 , US8201609B1 and WO2010/010542 A2.
• sunshade apparatuses involve time-consuming and awkward procedures both for assembly and, when necessary, removal of the slats. Moreover, these sunshade apparatuses, too, are subject to unwanted vibrations of the slats relative to the slat mounting structure.
• the aim of this invention is to overcome the above mentioned disadvantages of the prior art by providing a system for connecting a slat to a connecting mechanism of a sunshade apparatus and a method for its use.
• this invention has for an aim to provide a system for connecting a slat to a connecting mechanism of a sunshade apparatus and a method for its use which are particularly simple and flexible.
• a further aim of the invention is to provide a system for connecting a slat to a connecting mechanism of a sunshade apparatus and a method for its use which are particularly robust and reliable.
• the sunshade apparatus comprises at least one slat having a guide integral therewith and extending along a longitudinal direction of the slat.
• the sunshade apparatus comprises at least one movement element configured to be coupled to one end of the slat and one 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.
• the guide is elongated along the longitudinal direction.
• the locking element is operatively connected to the guide of the slat, to hang on the slat and to slide freely along the guide along the longitudinal direction.
• the guide of the slat comprises at least one track oriented along the longitudinal direction.
• the slat comprises a first track and a second track.
• said at least one track has L-shaped profile.
• the locking element has a profile which is shaped to match the profile of the movement element.
• the locking element has one or more engagement portions for connecting to said at least one track of the guide of the slat.
• the locking element has a profile which is shaped to be coupled to the guide (in particular to said at least one track), preferably through the engagement portions.
• the sunshade apparatus comprises an elastic structure, having a first configuration of non-interference with the movement element and a second configuration where it operates on the movement element to apply a force perpendicular to a contact surface between the slat and the movement element.
• the elastic structure is configured to move to the second configuration when the locking element is in the active position.
• the elastic structure allows coupling the movement element securely to the slat, preventing the movement element from moving relative to the slat in a direction perpendicular to a contact surface between the slat and the movement element. It should be noted that this solution allows reducing vibrations.
• the locking element is provided with at least one guide engagement portion configured to be coupled to the guide in such a way that the locking element can slide along the guide in the longitudinal direction.
• the locking element comprises a base and a pair of side walls (that is, a first side wall and a second side wall).
• the locking element comprises a first and a second side wall provided with portions for engaging the slat guide.
• the locking element is elastically deformable between a first configuration and a second configuration, to form the elastic structure.
• the locking element is made of a resilient material and is configured to bend about the longitudinal direction.
• the first and second side walls of the locking element are elastically deformable to allow the base of the slat to be positioned in a first position, when the locking element is in the deactivated position, and a second position, when the locking element is in the active position, where the base at the second position is at a greater distance from the slat than it is at the first position.
• the slat comprises a first track and a second track, integral with the slat and having L-shaped profiles (or hook-shaped profiles).
• the first and second tracks define the guide.
• each of the first and second tracks comprises an L-shaped profile (or hook-shaped profile) extending from a rear face of the slat.
• the hook-shaped profiles of the first and second tracks are opposite and outward-facing.
• the hook-shaped profiles of the first and second tracks are opposite and inward-facing.
• the first side wall of the locking element comprises a first ledge and the second side wall comprises a second ledge.
• each ledge defines, with the respective side wall, a profile having the shape of an upturned L. These upturned L-shaped profiles are thus configured for coupling to the L-shaped profiles of the first and second tracks.
• the locking element is C-shaped for coupling to the guide.
• the locking element is omega-shaped for coupling to the guide.
• the movement element comprises a connecting pin and a head configured to be coupled to the slat.
• the head of the movement element has a trapezoidal cross section.
• a first contact surface of the movement element delimited by a minor base of the trapezoidal cross section is in contact with the rear face of the slat.
• the locking element comprises a front part and a rear part. The front part faces towards an end of the slat where the locking element couples the slat to a movement element.
• the front part has a flared portion defining a guide for facilitating insertion of the movement element into the locking element.
• the locking element can be coupled to the movement element by interference.
• the flared portion is in contact with the movement element. More specifically, if the movement element has a trapezoidal cross section, the locking element at the active position touches a second surface of the movement element, delimited by a major base of the trapezoidal cross section so as to press the movement element against the rear face of the slat and to cancel out vibrations by preventing the rear face from moving in the perpendicular direction.
• the locking element is configured to house the movement element securely between its side walls and base (substantially without slack).
• the locking element has a profile which is shaped to match the profile of the movement element and to be coupled to the guide by means of the engagement portions.
• the base thus defines an abutment wall for the movement element.
• the elastic structure comprises a wedge- shaped elastic element, operatively interposed between the movement element and the locking element positioned at the active position, for generating the force in a direction perpendicular to a contact surface between the slat and the movement element.
• the wedge is in the shape of a U and has at least a first bent end which constitutes an abutment by which the elastic element is stopped on the movement element so that when the wedge is inserted, the wedge is prevented from moving lengthways further towards the end of the slat.
• a method for assembling a sunshade slat in a sunshade apparatus having at least one movement element and one locking element to removably connect the slat to the movement element.
• the method comprises the following steps:
• the movement of the locking element into the active position generates an elastic force perpendicular to a contact surface between the slat and the movement element.
• the movement of the locking element into the active position comprises inserting the movement element into the locking element by interference and elastically deforming the locking element.
• the method comprises a further step of interposing a wedge-shaped elastic element between the movement element and the locking element to generate the elastic force perpendicular to a contact surface between the slat and the movement element.
