Description

The invention relates to a cremone bolt or locking bolt with associated control means for a farm gate formed by a upper wing and lower wing pivotally mounted, individually and around a vertical axis, on a frame dormant, said cremone bolt or bolt-lock recessed at the level of the upper leaf comprising at least one control housed in a box and designed to act on one or more operating rods extending above and below said housing, at the back of a headrest which is rendered integral with the latter, while said control means are designed to be mounted on the lower leaf.

The invention will find its application in the field of building hardware and concerns, more particularly, cremones or cremones-locks for farm door.

As is apparent from the above description, a door farmer is composed of a top leaf and a leaf lower pivotally mounted, individually and around a vertical axis, on a sleeping frame. It has the advantage of allow the opening, as the case may be, of the upper leaf or lower leaf alone, leaving the other leaf closed. It can, of course, behave like a conventional door, the two leaves are often likely to be joined relative to each other through means appropriate.

In fact, it is very common to equip, both the flying higher than the lower leaf, of a lever or lever-bolt, each with a housing on which is able to act the user by means of a key and, more usually by means of a button or control handle. Above or, as the case may be, below such a housing extends an operating rod intended to act on one or more locking elements such as a tilting bolt, a roller, even on the mechanism of an auxiliary box containing a deadbolt likely to be brought into a position of interlock to cooperate with a matching strike on the sleeping frame. Obviously, these cremones or locks must, in these conditions, be handled individually. Each of them has a particular configuration, depending on its application to the upper leaf or to the lower leaf. In effect, the bolt or bolt-lock of the upper leaf will have a configuration so that the housing and, therefore, the means controls, such as a handle for example, are easily accessible. In fact, this position of the handle or the like often at the level of an upper leaf that of a door or standard French window.

Contrary, the gearbox or lever-lock coming to equip the lower leaf is usually arranged along the front upright and as close as possible to the sleeper superior of the latter. In any case, the means of control of this cremone bolt or cremone bolt lower are placed very low forcing the user to bend down to get there.

We also know, from document FR-A-2 627 796, which describes the characteristics mentioned in the preamble to the claim 1, a fitting for farm gate also comprising, for each leaf, a cremone bolt or bolt lock with a rod individually actuated operation. This fitting includes still elastic return connection means provided with a part, means for automatically hooking them together rods for bolts or bolts-locks when locking of the upper leaf and, on the other hand, means for detach the said rods by action on the lever or cremone bolt of the lower leaf. In a way, it here, it is a fitting whose control of the lever or cremone bolt of the upper leaf ensures, simultaneously locking and unlocking both , the cremone bolt or bolt-lock of the upper leaf automatically cooperating with that of the lower leaf, especially when the latter are both closed on their Framework sleeping.

If this solution makes it easier to handle the door user-friendly, the fact remains that the design hardware, so bolts or bolts-locks coming from equipping each leaf is specific and requires specific manufacturing management. Likewise, the carpenter must have such fittings in stock, or even in different lengths, to be able to meet the demand of its clientele in terms of farm gate.

The present invention is intended to remedy the aforementioned drawbacks through a cremone bolt or bolt lock which, although applicable to a farm gate, adopts a configuration almost identical to a cremone bolt or lever-lock for classic door or French window comprising only one leaf.

In fact, instead of being obliged to keep cremones in stock or cremone bolts specific for such farm doors, the carpenter is given the opportunity to use elements of traditional locking fittings for identical results specific fittings for this purpose.

According to an advantageous embodiment of the present invention, the assembly, sections of operating rod and crosscut headrest, is designed to be recessed in rebate of the front upright of the lower leaf, the connection means of said section of intersected operating rod being designed to cooperate with a bevel gear extending, in part, from a part, in rebate of this amount before said lower leaf and, on the other hand, in the rebate of the upper crosspiece of this latest.

As is already apparent from this embodiment preferential of the invention, it provides the advantage of ability to use a traditional lever or lever which is distinguished only by the cutting zones identified on the part of the headrest and the rod extending below the housing. Then after cutting, we are in the presence, all first, a lever or bolt-lock scheduled to come equip the upper leaf and, moreover, a set, formed by a section of rod and headrest, which is suitable, himself, to take position in rebate of the amount before the beating lower and cooperate either directly with a locking bolt, for example, either with a bevel gear standard fact allowing to reject the means of control, likely to act on this intersected rod, along the upper cross member of the lower leaf.

Ultimately, through this invention the shoeing of a farm gate basically does not require resources distinct compared to those used for a door or more traditional window.

The present invention will be better understood on reading the detailed description to follow and attached drawings relating to exemplary embodiments.

Figure 7 shows the same bolt lock in elevation.

As shown in Figure 1 of the accompanying drawings, the present invention relates to the field of farm doors and to relates to a fitting for such a door 1.

More particularly, a farm gate 1 has a leaf upper 2 and a lower leaf 3 pivotally mounted, individually around a vertical axis 4A, on a frame standing 4. These leaves 2,3 are, therefore, able to be folded down independently on this sleeping frame 4 or, at otherwise it is it is possible to open either one or the other. In these conditions, they each comprise locking means precisely allowing them to be closed individually on said sleeping frame.

In fact, as can be seen in FIG. 2, the invention relates to a cremone bolt or bolt lock 5 applicable to such a farm door 1. This cremone bolt or cremone bolt 5 comprises at least one mechanism control housed in a housing 6 and provided capable of acting on one or operating rods 7.8 extending above and below it housing 6, at the rear of a headrest 9 with which this latest.

This cremone bolt or locking bolt 5 is very particularly provided to be recessed in a recessed recess groove, in particular in rebate 10.11 of the amount before 12.13 of these leaves 2.3. As for the maneuvering rod (s) 7.8, they come to act on locking elements 15,16 which can borrow different embodiments. So, such elements of locking 15,16 can be defined by simple rollers or pebbles, just like by tilting bolts, even by bolts frames taking position in auxiliary boxes 17,18 rendered secured to the headrest 9, on either side of the central box 6.

The user can intervene on the control mechanism that contains the latter via a handle or button order, or, if necessary, using a key.

According to the invention and as shown in Figure 2, said headrest 9 of this cremone bolt or locking bolt 5 comprises, more particularly on its front face 19, at least one cutting mark 20 in its portion 20A extending below the housing 6.

Furthermore, the operating rod 8 extending below said housing 6 is, on the one hand, provided capable of being subdivided by intersection in an area 21 substantially at the right of the reference mark cutout 20 of the headrest 9 and, on the other hand, comprises, in particular in said zone 21, connection means 22, such as a toothing 23 on one and / or the other of its side edges 24, designed capable of cooperate with connection means 25 of conjugate form associated, either directly to means 26 provided for actuating the section of maneuvering rod intersected 27, either by means of transmission 28 coming to connect said rod section 27 to such means 26.

Finally, starting from a bolt or bolt lock 5 of standard configuration, we carry out a first operation of cutting during which both the headrest 9 and the rod 8 are cut to the height of the cutting mark 20. Then, optionally, the rod section is cut to length 27 to be able to adjust this assembly 5A, section of headrest 9A and section of rod 27 intersected, compared to said means of command 26 with which it is brought to cooperate, directly or by means of transmission 28.

Thus, according to a preferred embodiment shown in the FIG. 3, this assembly 5A, sections of operating rod 27 and of cross-cut headrest 9A, is designed to be recessed in rebate 11 of the front upright 13 of the lower leaf 3. The connection means 22 of said section of intersected operating rod 27 are designed to cooperate with transmission means 28 in the form of a reference angle 29 extending partly, on the one hand, into rebate 11 of this upright 13 of said lower leaf 3 and, on the other hand, rebate 30 of the upper cross member 31 of the latter.

As can still be seen in FIG. 4, at this angle reference 29 are therefore associated the connection means of conjugate form 25 having such a section of section 32 of U-shaped section. This one delimits, therefore, a groove in which is able to take position the intersected end 33 of the rod section 27. This end 33 therefore has on its side edges 24 the teeth 23, to which reference was made above, and which are provided to cooperate with suitable teeth 34 on the internal side of the parallel walls of said section section 32 in "U".

In the rebate 30 of the upper cross member 31, the said bevel gear 29 cooperates with control means 26, shown under shape of a simple cremone bolt 26A in figure 3.

Such control means 26 may also arise, advantageously, in the form of a lock bolt 50, as illustrated in FIGS. 6 and 7. Such a locking bolt 50 is, here again, designed to be fitted into a fitting groove that includes in rebate 30 of the upper cross member 31 of the leaf lower 3. This locking bolt 50 is distinguished from a locking lever 26A traditional in that along the front face 51 of its headrest 52 is hinged mounted a lever 53 capable of acting, as the case may be directly or via a connecting rod 56, on the one or more rods 54, 55 extending under this headrest 52, for their communicate a movement in the direction of locking or unlocking. This lever 53 therefore comes to extend in the axial extension of said headrest 52 in the locked position allowing to close, also, the upper leaf 2 of the farm door 1. Unlike for unlocking, we come move it away from this position.

Obviously, there are many other embodiments than that shown by way of example in these figures 6 and 7 of a such bolt lock.

As for the remaining upper part of the cremone bolt or bolt lock 5, after recutting, it is housed in a groove rebate installation 10 of the front upright 12 of the leaf upper 2. Fixing means 35 are provided to guarantee the fixing against the joinery of the lower end cut 36.36A, respectively, of the headrest 9 and the operating rod 8 extending under the housing 6.

Advantageously, such fixing means 35 constitute, substantially, a rod exit guide 8, at the angle 37 of the upright before 12 and lower cross member 38 of this leaf upper 2. Under these conditions, this end 36A of said operating rod 8 is able, in the locking position of the cremone bolt or cremone bolt 5, to be projecting relative to to this lower cross 38, to cooperate with a strike 39 coming to equip the angle between the front upright 13 and the cross-member upper 31 of the lower leaf 3. Note that such a strike 39 may be constituted, in the presence of a bevel gear 29, by a simple opening in the horizontal branch 40 of the headrest 41 of this angle reference 29.

One can, of course, imagine a reverse construction of such locking means 42 capable of locking the leaf upper 2 on the lower leaf 3 when the farm door 1 is closed on its sleeping frame 4. In this case, it is the end of the vertical rod portion of this bevel gear 29 which is suitable for projecting from the upper cross member 31 of this lower leaf 3, this in the locking position of the control means 26, therefore of the bolt-lock, to come engage in a strike arranged in correspondence on the leaf higher 2.

These locking means 42 can still adopt many other embodiments. In particular, the cremone bolt 26A or the cremone bolt 50, corresponding to the control means 26 associated with the lower leaf 2, can, in known manner, act through its own rods 43,44; 54,55, on rollers 46 (visible in broken lines in Figure 3) which, in position locking, are provided to engage in strikes that comprises, under these conditions, the lower cross member 38 of the leaf higher 2.

Advantageously, the farm gate 1 also includes means 47 to temporarily secure the upper leaf 2 to the leaf lower 3, when these are folded in the same alignment vertical. This allows the two leaves to be manipulated simultaneously 2,3 and therefore facilitates total opening or even closing of this farm door 1. Such means 47 have been shown in Figure 6 as an example of production. One of the elements of these means therefore consists of automatic strike 48, also known to those skilled in the art, which comes to equip in rebate, that is to say the lower cross 38 upper leaf 2, i.e. the upper cross member 31 of the wing lower 3, while, conversely, the upper cross member 31 of this lower leaf 3 or the lower cross member 38 of the wing upper 2 receives, in rebate, a locking finger 49 provided for engage in this waste 48.
