    Detailed description of the invention
  • The object of this invention is a locking system for a pergola-type canopy, which by means of two mechanical parts and with a simple movement enables the canopy to be locked in the position wherein the two mechanical parts converge, it likewise enables the position of the canopy to be unlocked without any additional element.
  • A pergola-type canopy is formed by a fabric (1), joined at one end to a fixed point and at the opposite end joined to a transverse end member (2), such that the transverse end member (2) moves guided on two parallel lateral guides (3) from the fixed point towards the end of the lateral guides (3) opposite from the fixed point, extending the fabric (1) in this movement. In order to prevent the fabric (1) from folding in an undesired movement of the transverse end member (2), the pergola-type canopy requires a mechanism which locks the position of the transverse end member (2) in a point of the lateral guides (3).
  • The system object of the invention comprises in the preferred embodiment two tilting parts (4) in the transverse end member (2), in correspondence with the portions of the transverse end member (2) which are in contact with the lateral guides (3). Each tilting part (4) is joined to the transverse end member (2) by means of a joint (5) which enables the free rotation of the tilting part (4) with respect to the transverse end member (2); furthermore, the tilting part (4) has a certain length (L) which is important for the operations of the system object of the invention.
  • In the preferred embodiment of the invention, the tilting part (4) makes up a first component (6) which, in addition to the tilting part (4) and the joint (5), has a fastening part (7) for fastening to the transverse end member (2) which incorporates the joint (5) and joins the tilting part (4) to the transverse end member (2). The joint (5), as explained previously, enables the free movement of said tilting part (4) around the joint (5) itself with respect to the transverse end member (2), thus the tilting part (4) has a free end (8) and an articulated end (9).
  • The tilting part (4) is a part that is fastened to the joint (5), and the movement thereof depends either on the force of gravity or on an elastic means (not shown in any figure) to which the mentioned tilting part (4) is fastened.
  • The system object of the invention comprises, in each lateral guide (3) of the pergola-type canopy, at least one housing (10). In the preferred embodiment of the invention, the housing (10) is a part fastened to each lateral guide (3), however it could be that each lateral guide (3) has a housing (10) incorporated in the lateral guide (3) itself. The housing (10) comprises two inclined planes (11, 12) which converge making up a stop (13). The two inclined planes (11, 12) of the housing (10) are divided in a first inclined plane (11) that is approximately horizontal and a second inclined plane (12) that is approximately vertical. The first inclined plane (11) is longer than the second inclined plane (12), so that the first inclined plane (11) can guide the tilting part (4) towards the stop (13) when the tilting part (4) rotates around the joint (5) having passed the end of the second inclined plane (12).
  • Thus, the housing (10) is configured to, if desired, house in the stop (13) the free end (8) of the tilting part (4) preventing a movement of the transverse end member (2) towards the fixed point of the canopy, as explained later in this specification, and to enable a free movement of the transverse end member (2) towards the fixed point of the canopy, if that is what is desired, performing a movement of the transverse end member (2) on the lateral guides (3) and without needing any additional components.
  • In order to finish defining the system object of the invention, it is necessary to define that between the joint (5) and the housing (10), specifically between the joint (5) and the end of the first inclined plane (11) there is a distance (d) that is less than the length (L) of the tilting part (4).
  • The locking of the canopy is performed according to the following sequence of movements:
    • the transverse end member (2) moves on the lateral guides (3) moving away from the fixed point of the canopy until it passes the second inclined plane (12), at which point the free end (8) of the tilting part (4) falls on the first inclined plane (11),
    • the transverse end member (2) moves in the direction towards the fixed point of the canopy, such that the free end (8) of the tilting part (4) stays pinned in the stop (13) of the housing (10), thereby preventing the movement of the transverse end member (2) and the canopy therefore staying pinned in that position.
  • To unlock the canopy, the following sequence of movements is performed:
    • the transverse end member (2) is moved away from the fixed point until the tilting part (4) moves out of the housing (10) by the effects of gravity or by the effects of an elastic means,
    • the transverse end member (2) is moved towards the fixed point of the canopy, such that the tilting part (4), in the movement of the transverse end member (2) towards the fixed point of the canopy, makes contact with the end of the first inclined plane (11), but such that the free end (8) of the tilting part (4) does not point towards the stop (13), this is achieved by the effects of the relationship between the distance (d) between the joint (5) and the end of the first inclined plane (11) and the length (L) of the tilting part (4).
  • In order to protect the housing (10) and improve the operation of the system object of the invention, guiding the movement of the tilting part (4) in the interaction thereof with the housing (10), the system object of the invention comprises a protective plate (14) which covers the inclined planes (11, 12) and the stop (13) and contributes to the pinning of the free end (8) of the tilting part (4) in the stop (13) itself.
  • The invention is not intended to be limited to the specific embodiment described in this document. Those skilled in the art may develop other embodiments in light of the description made herein. As such, the scope of the invention is defined by the following claims.
