Description

- 1 -

  The invention relates to a door fitting for a farmhouse door, consisting of a

  both upper and lower leaf, comprising, for each leaf, a

  cremone or espagnolette-lock having an actuating rod actuated indi-

  vidually. This invention will find its application, more particularly, in the

  building hardware sector.

  There are already known fittings adapted to farm doors consisting of two leaves separate and articulated around the same vertical axis. Thus, these fittings generally consist of two distinct parts, one of which is a cremone or espagnolette-lock applied to the upper leaf, the other part,

  secured to the lower leaf, being formed by a simple lock. In fact, this

  the provision imposes a separate command of the espagnolette or espagnolette lock and the lock to obtain the opening of the two leaves of the door. Indeed, the operation of the cremone or espagnolette-lock of the upper leaf does not affect

  the lower flap, the latter being considered, in this case, as part of

integral part of the sleeping frame.

  Consequently, the drawbacks of this type of known fitting essentially lie in the multiple manipulations that it is necessary to perform when opening and closing the doors of the door.

farmer.

  In order to reduce the number of these manipulations,

  composed of two cremones or espagnolettes-locks applied, respectively

  on the upper leaf and the lower leaf of said farm door. Cha-

  one of these cremones or espagnolettes-locks comprises at least one rod of

  one or more locking elements capable of

  peach with caches arranged on the sleeping frame. This or these rods

  are actuated via a mechanism housed in a housing

  and on which the user acts by means of a control handle.

  The peculiarity of this type of hardware is that at the junction of the two leaves of the door fermière, a rod of maneuvering the cremone or espagnolette-lock of the upper leaf cooperates with a rod of

  maneuver of the cremone or espagnolette-lock of the lower wing. More precise-

  this upper leaf of the upper leaf has at its lower end a hook in which the upper end curved with

  the operating rod located on the lower battoant.

  It is important to note that the cooperation of the maneuver rods

  is effective only in the locking position of the farmhouse door. Thus, this

  the configuration allows, under a single action on the handle of

  handle of the cremone or espagnolette-lock superior to obtain, simultaneously, the

  unlocking the two leaves of the door. However, such an activity

  the destruction of the link connecting the operating rods of the upper and lower drums and leads them to disassociate. As a result, the user is obliged to manipulate these two

  during the opening and closing of the farm gate.

  Furthermore, in case the upper leaf is in the unlocked position and, unlike the lower leaf locked, it is essential to proceed, initially, to unlock the latter. Then, the two leaves are brought in the same vertical plane in order to obtain the cooperation of their

  respective operating rods before closing and locking the iron door.

  Mière. This locking is carried out under these conditions by the action of

  ger on the control handle of the upper cremone or espagnolette-lock.

  It is undeniable that this type of known hardware only partially

  the problem of the multiple manipulations which it is necessary to carry out

  during the opening and closing of a farmer's door. However, this incon-

  This is all the more embarrassing because it causes a deterioration

  Pide of the rods of maneuver and the mechanism of the cremones or cremonesserrures

  because of frequent errors in the order of execution of

  Locking and unlocking.

  The present invention aims to remedy all the disadvantages

  aforementioned goods by proposing a door handle fitting whose order

  and handling are particularly convenient and rational.

  For this purpose, the invention relates to a fitting for a farm gate, formed

  an upper leaf and a lower wing, comprising, for each bat-

  both a cremone or espagnolette-lock having an actuating rod action-

  individually characterized by the fact that it includes means of

  elastic return link provided, on the one hand, with means for automatically switching on

  the operating rods of the cremones or espagnolettes-locks

  locking the upper leaf and, on the other hand, means for desolating

  dariser said said maneuvering rods by action on the espagnolette or espagnolette-ser-

of the lower wing.

  The advantages achieved by this invention consist, essen-

  that the elastic return connection means

  to hold in cooperation the operating rods, respectively, of the inner flap

  lower and upper leaf after unlocking the latter. It is pos-

  Thus, 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 espagnolette or espagnolette-lock of the lower leaf that the we dissociate this

  last compared to the upper leaf.

  On the other hand, the two doors of the farm gate were separated

  during a previous manipulation, the self-locking means

  can be used to reconstitute the connection of the operating rod of the

  lower flap with that of the upper flap by a simple action of ver-

  rusting of the espagnolette or lock-lock located on the latter.

  It is a fact that such a fitting, according to the invention, is

  ease and therefore increased longevity due to a considerable reduction in

  risk of false maneuver.

  Other objects and advantages of the present invention will become apparent during

  of the following description given as a non-restrictive example and accompanied by

  of drawings in which: - Figure 1 is an elevational view of the fitting, according to the invention, the resilient return connection means being arranged in a housing of which a

with elastic return.

  Fig. 8 is a plan view of the jumper shown in Fig. 7.

  - Figure 9 shows the axis on which is pivoted the lever pre-

  city. The fitting 1, shown in FIG. 1 and constituting the subject of the present invention, is particularly intended for use in the

  frame of a farm gate 2 composed of an upper leaf 3 and a bat-

  so lower 4. Thus, this fitting comprises, for each of these leaves

  3.4 a espagnolette or espagnolette-lock 5.6 equipped with a mechanism 9 capable of ac-

  at least one operating rod 7.8.

  According to the embodiment represented in the different figures,

  these 7,8 maneuvering rods are housed in the front 12,13 respectively-

  3 and lower flap 4, and slide behind headrests 14,15. These generally have one or more openings through which emerge integral locking elements of said operating rods 7,8. By way of example, such locking elements may consist of rollers intended to cooperate with the strikes arranged

on the sleeping frame.

  According to one characteristic of the invention, the fitting 1 comprises means

  elastic return link 16 ensuring the cooperation of the control rod.

  7 of the cremone or espagnolette-lock 5 located on the upper leaf 3 with the operating rod 8 corresponding to the espagnolette or espagnolette 6 lock

  4. In fact, one of the interests of these means of liaison with

  resilient pel 16 is to authorize the: unlocking or locking of the two leafs 3,4 of the farm gate 2 by a simple action on one or the other of the espagnolette or espagnolette-locks 5,6 and, in particular, on that located

on the upper wing 3.

  As can be seen in FIG. 1, the elastic return linkage means

  16 are housed in a housing 17 (shown in more detail in the FIGS.

  2 and 3) secured to the lower end 18 of the headrest 14. This housing 17 has a section "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. Note that the wings 19,20 pre-

  feel on their edge before 22 a series of tongues 23 intended for crimping

  wise of the housing 17 on the headrest 14.

  Preferably, the resilient return link 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 inner face 27 and at the end

  lower section 28 of the operating rod 7.

  More precisely, the jumper 26, as represented in FIGS. 7 and 8, consists of a flat plate 29, preferably metal, cut and then folded,

  on its sides 30,31 so as to define two parallel wings in the form of an eye-

  let 32,33. In the latter, openings 34 are fitted to the dia-

  meter of the axis 25 and allowing the passage and the maintenance of it. In addition

  their, between the parallel wings 32,33 of the jumper 26, is inserted the middle portion 35 of the lever 24, the latter having a bore 36 traversed by the axis

  25. Preferably, said lever 24 is formed of two branches 37,38 se-

  tending, respectively, above and below its pivot axis. More

  exactly, the lower branch 38 has at its free end 39 a hook

  chet 40 for cooperating with the curved upper end 41 of the trin-

  operating lever 8 of the lower wing 4.

  In fact, the lower leg 38 of the lever 24, provided with its hook 40, serves to ensure the connection between the operating rods 7,8 of the

  cremones or espagnolettes-locks 5,6 respectively located on the upper leaf

  3 and the lower leaf 4 of the farm door 2.

  As for the upper branch 37 of the lever 24, the latter is subjected to resilient means 42 tending to move it away from the operating rod 7 and to push it against the vertical side 21 of the housing 17. The lower branch 38 and,

  in particular, the hook 40 are thus kept in the active position and susceptible

  to cooperate with the curved end 41 of the operating rod 8

férieure.

  Accordingly, by acting on the control handle of the espagnolette or espagnolette-lock 5 located on the upper leaf 3, the movement applied to the operating rod 7 is reflected directly on the operating rod 8 of the espagnolette or espagnolette-lock 6 of the lower wing 4. Because of this

  provision, it is possible to control, by a single operation, the lock

  simultaneous unlocking and unlocking of the upper 3 and lower 4 leaf of a

  farm gate2. The latter, reacting under these conditions as a standard

single-handed.

  It should be noted that during these maneuvers, the resilient return link means 16 move in their housing 17, the latter being fixed

  immovably on the headrest 14. Advantageously, this displacement is guiding

  die through the axis 25 on which pivots the lever 24 and whose ends 43,44 slide in oblong slots 45 machined in the

  parallel and vertical wings 19,20 of said housing 17.

  In addition, the axis 25 has at its ends 43,44 a recess 46,47

  to define a shoulder 48,49 for cooperating with the inner face

  dull of said wings 19,20. This feature avoids the unexpected release of the axis 25 of the housing 17. In addition, the length 50 of this axis 25 is defined so that after mounting, its ends 43,44 do not emerge wings 19,20

  and are substantially flush with the outer face 51 of the latter.

  However, it can be seen that such a provision creates certain

  mounting means of resilient return means 16. In particular, the engagement

  43,44 ends of the axis 25 in the oblong slots 45 may be particularly difficult, especially since this operation can be performed after mounting the axis 25 of the lever 24 on the rider 26

  integral with the operating rod 7. Thus, a method of mounting

  to cause the spacing of the wings 19,20 of the housing 17 to allow the

  passage of the axis25. However, this solution generates significant deformations

  of the casing 17 and the difficulties of assembling the latter on the head.

14.

  In order to solve these problems and eliminate any

  assembly, provision is made in the front edge 22 of the wings 19,20 of the housing 17 a

  horizontal section 55 leading to the upper end 56 oblong slots 45. This feature allows to engage, initially, the ends 43,44 of the axis 25 in the cutouts 55 to position, without much difficulty, to the

  right of oblong slots 45 in which they are slidable.

  The interest of a farm gate 2, consisting of two wings 3,4 is to allow the handling of these last individually. However,

  it is important that such a door can resume quickly, and without much

  of difficulty, the characteristics of a classic swing door. For this purpose, and according to one characteristic of the invention, the return link means

  16 have means 52 for automatically engaging the trimmers.

  maneuvers 7,8 cremones or lock bolts 5,6 when locked

the upper leaf 3.

  In fact, the function of these means 52 is to restore the link

  7,8 by means of a simple locking operation of the

  upper flap 3 while the lower flap 4 has previously been

  rust. This situation has been shown in FIG. 6. Thus, it can be seen that the operating rod 8 of the lower leaf 4 is in the lowered position.

corresponding to the lock.

  Furthermore, the curved end 41 of this operating rod 8 is de-

  25 of the lever 40 of the lever 24. In contrast, the operating rod 7 is

  in the raised position, the upper leaf being unlocked.

  According to a preferred embodiment, the means 52 for automatically switching on the operating rods 7, 8 are constituted by an end

  free cross 39, of the lower branch 38 of the lever 24 in the form of a rod 53.

  it is able to cause the withdrawal of said lower leg 38 to its passage in front of the curved end 41 of the control rod 8 when locking the espagnolette or espagnolette-lock 5. Figure 1 represents, in

  discontinuous lines, the position of the lever 24 during its erasure in front of the ex-

  curved end 41 of the operating rod 8. Due to the elastic means

  42, acting on the upper branch 37 of the lever 24, it always takes its active position at the end of the low stroke of the operating rod 7, the hook 40 cooperating, then, with the curved end 41 of

the operating rod 8.

  Advantageously, the resilient return link means 16 comprise, in addition, means 57 for disengaging the operating rods 7,8 from the espagnolettes or espagnolettes-locks 5,6 by action on the espagnolette or espagnolette-lock

  6 located on the lower leaf 4.

  In fact, the aim is, after unlocking the upper leaf

  3 and lower 4, to allow the disengagement of the curved end 41 of the operating rod 8 of elastic return link means 16 and,

  in particular, hook 40, this operation being carried out by a simple

  cremone or espagnolette lock 6 located on the lower leaf 4.

  For this purpose, the means 57 consist essentially of a

  an inverted "L" shaped cut 58 made on the front edge 22 and at the end

  lower portion 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. However, the length 60 of the vertical portion 61 of the cutout 58 is determined so that the only unlock action on. the cremone or

  espagnolette-lock 5 is not sufficient to position the curved section 62 of ladi-

  the operating rod 8 in agreement with the horizontal portion 63 of the cutout 58. As visible in Figure 4, showing the upper leaf 3 and the lower leaf 4 in the unlocked position, this curved section 62

  However, it is preferable that such manipulation is not reflected on the operating rod 7 of the blank.

  cremone or espagnolette-lock 5 of the upper wing 3.

  For this purpose, the means 57 are completed by a hook 40 associated with the lever 24 and allowing a vacuum stroke 64 of the operating ttingle 8 of the lower leaf 4 relative to the operating rod 7 of the upper leaf 3. In fact, 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.

  Thus, the action of the espagnolette or espagnolette lock 6 only affects this

  maneuvering rod 8 by conferring on it a displacement corresponding substantially

  to the empty stroke 64 aforesaid so as to allow the release of its curved end 41 of the housing 17 to finally disengage the wing

  lower 4 of the upper leaf 3.

  Preferably, the housing 17 and, in particular, the vertical wings 19, both have a cutout 58 allowing the reversibility of the fitting 1 and its use on a farm gate 2 opening to the right or

to the left.

  It is undeniable that such a fitting, according to the invention, provides

  a number of advantages compared to iron door fittings.
