Definitions

  • the present invention relates to a closure device for sliding leaves.
  • closure devices which comprise engagement elements that protrude from the front abutment edge to engage respective slots of the front edge of a complementary leaf or the doorjamb. After engaging the openings, said elements, by means of a cremone-bolt mechanism, are made to slide so as to engage the slots and retain the leaf in the closed position.
  • the aim of the present invention is to provide a device whose structure is such that it obviates the above drawbacks, i.e., it is capable of engaging automatically also when the engagement elements are not aligned with the respective engagement slots.
  • an object of the present invention is to provide a device which is structurally simple and flexible in use so that it can be applied to the various sliding leaves that are currently commercially available.
  • a closure device for a sliding leaf which comprises a cremone-bolt actuation system provided with at least one traction element for actuating a respective rod which is slidingly guided in a seat of the front edge of said leaf and is provided with at least one engagement element, said cremone-bolt actuation system being suitable to actuate the engagement of said element in a respective slot of an abutment post of said front edge, characterized in that it comprises a block which is connected to said rod and has an engagement seat for said traction element and a contrast element which is actuated by elastic means against said traction element in order to elastically retain said traction element in said seat, said seat being shaped so as to allow movements of said block with respect to said traction element when said rod is actuated in contrast with said elastic means.
  • the reference numeral 1 designates a profiled element that constitutes the front post of a conventional sliding leaf, the rest of which is not shown.
  • the profiled element 1 comprises two flat and mutually parallel walls 2 and 3 which are mutually connected by two transverse ribs 4 and 5 which form a longitudinal cavity 6.
  • the front edges of the post 1 converge and are internally provided with two mutually opposite ridges 7 and 8 which form a longitudinal seat 9 together with the rib 5.
  • a rod 10 having a flattened cross-section is slidingly guided in the seat 9, and engagement elements 11 are rigidly coupled to said rod; only one of said engagement elements is shown in Figure 1.
  • Each element is constituted by a flat plate which is perpendicular to the plane of the rod and lies along the centerline of the post.
  • Each flat plate 11 comprises a T-shaped head 12 provided with two axial and mutually opposite teeth 13 and 14 which form respective undercuts 15 and 16.
  • the tooth 13 has a chamfer 17 which forms, together with the undercut 15, an angle of approximately 45°.
  • the illustrated example assumes that the leaf engagement position is reached when the rod 10 is actuated in the direction A and that engagement is provided only by the tooth 13 and by the corresponding undercut 15.
  • the tooth 14 and the corresponding undercut 16 are ineffective in the illustrated example and are used if engagement must occur by moving the rod in the direction B, which is the opposite of A.
  • the tooth 13 is meant to engage a slot 18 of the post 19 against which the leaf is pushed.
  • the slot 18 is constituted by an undercut formed by a tooth 20 of a body 21 which is fixed frontally to the post 19.
  • the tooth 20 also has a chamfer 22 which is suitable to cooperate, as will become apparent hereinafter, with the chamfer 17 of the tooth 13.
  • the movement of the rod 10 in the directions A-B and therefore the engagement between the post 1 and the post 19 is determined by an actuation system of the cremone-bolt type, which is associated on an outer face of the profiled element 1 and is generally designated by the reference numeral 23.
  • Said actuation system 23 comprises a bracket 24 which is fixed to the rib 5 of the profiled element 11 by screws 25 and supports a box-like base 26 which accommodates an actuation mechanism which can be operated by means of an external lever 27 which, through adapted transmission means, moves in the direction A-B a traction flap or traction element 28 which protrudes into the longitudinal cavity 6.
  • the details of the cremone-bolt actuation system are not shown in the drawing since they are not pertinent to the present invention and in any case have a conventional structure.
  • the traction element 28 transmits the movement to the rod 10 by means of a connecting element which comprises a prism-shaped block 29, which joins the traction element 28 to the rod 10 through a slot 30 of the rib 5 of the profiled element 1 which is elongated so as to allow the sliding of the block 29.
  • the prism-shaped block 29, see particularly Figure 3 is fixed by means of two screws 31 to the rod 10, and a seat 32 is formed therein; the provision of said seat forms two end protrusions 33 and 34 on which screws 35 fix a bridge 36 which closes the seat 32.
  • the seat 32 has two flat and mutually opposite faces 37 in which, along approximately half of their length, grooves 38 are provided which are parallel to each other and to the rod 10 and form a step 39.
  • the grooves 38 act as a guide for a contrast element which is constituted by a pusher 40 on which two springs 41 act; said springs are interposed between said pusher and the protrusion 33.
  • the pusher 40 has, on two opposite edges, ridges whose cross-section is complementary to the cross-section of the grooves 38 and keep it guided during any mutual sliding movements of the step 39 on one side and of the protrusion 33 on the opposite side.
  • the seat 32 is meant to be engaged, in the position in which the actuation system 23 is mounted on the profiled element 1, by the traction flap 28 which, by means of the springs 41, is kept against the protrusion 34 by the pusher 40.
  • the described device works as follows. By actuating the lever-operated actuation system 23, the rod 10 is made to slide in the longitudinal seat 9 so that, when the leaf abuts against the post 19, the tooth 13 can engage the slot 18. The leaf is thus locked shut by means of the engagement produced by the mutual coupling of the teeth 13 and 20.
  • the tooth 13 disengages from the slot 18, allowing to open the leaf. Accordingly, in normal leaf closure and opening operations the device works in a fully conventional manner.
  • the described invention perfectly achieves the intended aim and object.
  • the yielding of the rod 10 during closure, allowed by the springs 41 prevents the engagement teeth 13 and 20 from being subjected, by striking each other, to deformations which would compromise the perfect operation of the leaf to the point of preventing its closure and opening.
  • the yielding of the rod 10 with respect to the traction element 24, produced by the springs 41 ensures automatic closure of the leaf, i.e., closure without having to operate the cremone-bolt actuation system.
  • Figures 4 and 5 illustrate a different embodiment in which the components that are identical or correspond functionally to those of the embodiment of Figures 1-3 are designated by the same reference numerals.
  • the block 29 is provided with lateral fins 42 by means of which it is guided in a slot 43 of the profiled element 1, and the rod 10 is composed of a pair of strips 44 and 45 rigidly coupled to a pair of pivots 46 and 47 which protrude from the block 29.
