Definitions

  • the invention relates to a fitting for a farm gate, formed by an upper leaf and a lower leaf, comprising, for each leaf, a cremone bolt or cremone bolt provided with an individually actuated operating rod, of the type according to the preamble. of claim 1.
  • This invention will find its application, more particularly, in the field of building hardware.
  • Fittings are already known which are suitable for farm doors consisting of two separate leaves and articulated around the same vertical axis.
  • these fittings generally consist of two separate parts, one of which is a cremone bolt or lock bolt applied to the upper leaf, the other part, integral with the lower leaf, being formed by a simple lock.
  • this arrangement requires a separate control of the lever or lever-lock and the lock to obtain the opening of the two leaves of the door.
  • the operation of the bolt or lever-lock of the upper leaf does not affect the lower leaf, the latter being considered, in this case, as an integral part of the frame.
  • fittings have been designed composed of two cremones or cremones-locks applied, respectively, to the upper leaf and the lower leaf of said farm gate.
  • Each of these bolts or bolts-locks comprises at least one operating rod carrying one or more locking elements capable of cooperating with strikes arranged on the frame. This or these operating rods are actuated by means of a mechanism housed in a housing and on which the user acts using a control handle.
  • this type of fitting is that at the junction of the two leaves of the farm door, a rod of actuation of the lever or lever-lock of the upper leaf cooperates with a rod of operation of the lever or lever-lock of the lower leaf. More specifically, this operating rod of the upper leaf has at its lower end a hook in which engages the upper curved end of the operating rod located on the lower leaf.
  • the present invention aims to remedy these drawbacks.
  • the invention as characterized in the claims resolves the problem and consists of a fitting for a farm gate, formed by an upper leaf and a lower leaf, comprising, for each leaf, a cremone bolt or locking bolt provided with an actuating rod actuated individually, this fitting comprising connecting means between the upper leaf and the lower leaf with elastic return provided, on the one hand, with means for automatically engaging the rods for operating the bolts or bolts-locks when the upper leaf is locked and, on the other hand, means for separating said operating rods by action on the lever or lever-lock of the lower leaf.
  • the advantages obtained thanks to this invention consist, essentially, in that the elastic return connection means make it possible to maintain in cooperation the operating rods, respectively, of the lower leaf and the upper leaf after unlocking of the latter. It is thus possible to control the opening and closing of the farm gate as an opening composed of a single leaf. In fact, it is only by acting on the cremone bolt or cremone bolt of the lower leaf that the latter is separated from the upper leaf.
  • the automatic engagement means make it possible to reconstitute the connection of the operating rod of the lower leaf with that of the upper leaf. by a simple locking action of the lever or lever-lock located on the latter.
  • the fitting 1, represented in FIG. 1 and constituting the object of the present invention, is more particularly, intended for use in the context of a farm gate 2 composed of an upper leaf 3 and a lower leaf 4
  • this fitting comprises, for each of these leaves 3, 4 a cremone bolt or cremone bolt 5, 6 provided with a mechanism 9 capable of actuating at least one operating rod 7, 8.
  • these operating rods 7, 8 are housed in the front edge 12, 13 of the upper leaf 3 and lower leaf 4 respectively, and slide behind head plates 14, 15. These generally have one or more openings through which emerge locking elements integral with said operating rods 7, 8.
  • locking elements may consist of rollers intended to cooperate with the strikes arranged on the sleeping frame.
  • the fitting 1 comprises elastic return connection means 16 ensuring the cooperation of the operating rod 7 of the cremone bolt or locking bolt 5 situated on the upper leaf 3 with the corresponding operating rod 8 to the bolt or bolt lock 6 of the lower leaf 4.
  • elastic return connection means 16 consists in authorizing the unlocking or locking of the two leaves 3, 4 of the farm door 2 by a simple action on one or other of the bolts or bolts-locks 5, 6 and, in particular, on that located on the upper leaf 3.
  • the elastic return connection means 16 are housed in a housing 17 (shown in more detail in Figures 2 and 3) secured to the lower end 18 of the headrest 14.
  • This housing 17 has a section in the shape of a "U" open laterally and composed of two wings 19, 20, vertical and parallel, interconnected by a vertical flank 21 constituting the bottom of said housing 17.
  • the wings 19, 20 have on their front edge 22 a series of tongues 23 intended for crimping the housing 17 of the headrest 14.
  • the elastic return connection means 16 are constituted by a lever 24 pivotally mounted on a horizontal axis 25. This is held by a rider 26 attached to the internal face 27 and to the lower end 28 of the rod. operation 7.
  • the jumper 26, as shown in Figures 7 and 8, consists of a flat 29, preferably metallic, cut then folded, on its sides 30, 31 so as to define two parallel wings in the form of eyelet 32, 33.
  • openings 34 adjusted to the diameter of the axis 25 and allowing the passage and maintenance thereof.
  • the middle part 35 of the lever 24 is inserted, the latter having a bore 36 crossed by the axis 25.
  • said lever 24 is formed of two branches 37, 38 extending respectively, above and below its pivot axis. More precisely, the lower branch 38 has at its free end 39 a hook 40 intended to cooperate with the curved upper end 41 of the operating rod 8 of the lower leaf 4.
  • the lower branch 38 of the lever 24, provided with its hook 40, has the function of ensuring the connection between the operating rods 7, 8 of the bolts and bolts-locks 5, 6 located respectively, on the upper leaf 3 and the lower leaf 4 of the farm gate 2.
  • the elastic return connection means 16 move in their housing 17, the latter being fixed immutable on the headrest 14.
  • this movement is guided through of the axis 25 on which the lever 24 pivots and whose ends 43, 44 slide in oblong slots 45 machined in the parallel and vertical wings 19, 20 of said housing 17.
  • the axis 25 has at its ends 43, 44 a recess 46, 47 making it possible to define a shoulder 48, 49 intended to cooperate with the internal face of said wings 19, 20. This feature prevents the axis from being released unexpectedly. 25 of the housing 17. Furthermore, the length 50 of this axis 25 is defined so that after mounting, its ends 43, 44 are substantially flush with the external face 51 of the wings 19, 20.
  • the advantage of a farm gate 2, composed of two leaves 3, 4 consists in authorizing the handling of the latter individually. However, it is important that such a door can quickly, and without great difficulty, resume the characteristics of a conventional swing door.
  • the elastic return connection means 16 comprise means 52 for automatically engaging the operating rods 7, 8 cremone bolts or locks 5, 6 when the upper leaf 3 is locked.
  • this operating rod 8 is released from the hook 40 of the lever 24.
  • the operating rod 7 is in the raised position, the upper leaf being unlocked.
  • the means 52 for automatically engaging the operating rods 7, 8 are constituted by a free end 39, of the lower branch 38 of the lever 24 in the form of a cam 53. This is able to cause the withdrawal of said lower branch 38 as it passes in front of the curved end 41 of the operating rod 8 when the cremone bolt or bolt lock is locked 5.
  • FIG. 1 shows, in broken lines, the position of the lever 24 when its erasure in front of the curved end 41 of the operating rod 8. Due to the elastic means 42, acting on the upper branch 37 of the lever 24, the latter systematically returns to its active position at the bottom end of the operating rod 7, the hook 40 cooperating, then, with the curved end 41 of the operating rod 8.
  • the elastic return connection means 16 also comprise means 57 for separating the operating rods 7, 8 of the bolts or bolts-locks 5, 6 by action on the bolt or bolt-lock 6 located by the lower leaf 4.
  • the aim sought after, after unlocking the upper leaf 3 and lower leaf 4 is to authorize the release of the curved end 41 of the operating rod 8 from the elastic return connection means 16 and, in particular, of the hook 40, this operation being carried out by a simple control of the lever or lever-lock 6 located on the lower leaf 4.
  • the means 57 consist substantially of an inverted "L" shaped cutout 58 produced on the front edge 22 and at the lower end 59 of at least one wing 19, 20 of the housing 17.
  • This cutout 58 is intended for the passage of the curved end 41 of the operating rod 8.
  • the length 60 of the vertical portion 61 of the cutout 58 is determined so that the only unlocking action on the cremone bolt or cremone bolt 5 is not sufficient to position the curved section 62 of said operating rod 8 in accordance with the horizontal portion 63 of this cutout 58.
  • this curved section 62 is placed immediately below the horizontal portion 63 of the cutout 58.
  • the means 57 are supplemented by a hook 40 associated with the lever 24 and allowing an idle stroke 64 of the operating rod 8 of the lower leaf 4 relative to the operating rod 7 of the upper leaf 3.
  • this vacuum stroke 64 is obtained due to an opening 65 of the hook 40 substantially greater than the thickness of the curved section 62 of the operating rod 8.
  • cremone bolt or lock-bolt 6 only affects this operating rod 8 by giving it a displacement corresponding substantially to the above-mentioned idle stroke 64 so as to allow the release of its curved end 41 from the housing 17 to finally separate the lower leaf 4 from the upper leaf 3.
  • the housing 17 and, in particular, the vertical wings 19, 20 both have a cutout 58 allowing the reversibility of the fitting 1 and its use on a farm door 2 with opening to the right or to the left.
