Description

 The present invention relates to the locking of doors, gates, windows, French windows, shutters, etc.

with two leaves.

 More specifically, the invention relates to a keeper adapted to cooperate with a stop member, such as a bolt bolt, for locking doors, shutters, etc. with two leaves.

In the following, we will call
- "primary leaf", that of the two leaves which is adapted to be immobilized by means cooperating, on the one hand, with said leaf and, on the other hand, with the structure (floor and ceiling, frame, etc.) relative to which said leaf pivots, and
- "secondary leaf", the other leaf which is adapted to be immobilized by means cooperating, on the one hand, with said leaf and, on the other hand, with said primary leaf and / or with the structure with respect to which pivots said secondary leaf.

A lock is generally provided on one of the leaves and, opposite, one left on the other leaf
In the closed position, the edge of the said leaves, opposite their respective pivot axis, is placed essentially along a line which will be called the closing line ". It is understood that this line can in fact be a fairly wide area (rebate junction, wolf's mouth, overlap, doucine, etc ...).

 Doors with two leaves are the easiest to fracture, because it is easy to slide a weighing tool (crowbar) between the leaves and - by spreading the leaves - to extract the bolt from the strike. Garage doors are often with two doors and garages frequently communicating with the house through an ordinary door r it is often by attacking the garage door that criminals gain access to the house.

 Patio doors and double-leaf shutters are equally vulnerable.

 To remedy this situation, it is possible to provide the internal faces of the flaps and doors full of supports in which a safety bar is slid, largely straddling the closing line.

These safety bars, if they are generally effective, have several major drawbacks
- they are heavy to handle
- they are bulky when deposited
- their weight and length quickly make their installation binding, so that after a certain time, they remain deposited when they should be in use
- but above all, they can only be installed from the inside, which does not solve the problem of the last pair of shutters, or the door of a room which would be the only access.

 The object of the present invention is to remedy these various drawbacks and, to do this, it proposes a special structure keeper.

 More specifically, the keeper according to the invention is characterized in that it comprises two elements, one of which is permanently fixed to one of the leaves and the other of which is removable, one of these elements being a female element, the cavity has at least one access opening and the other element being a male element, the geometry and the dimensions of the section of said cavity and that of said male element allowing them to fit together such that a part, called "junction", of one of the elements is received in, or receives, the other, while the non-received, or non-receiving part, called "protruding", largely overflows beyond the closing line and into that one of the elements has a recess adapted to receive said movable stop member.

 In one embodiment of the invention, it is the female element which is adapted to be fixed permanently to one of the leaves it is therefore the male element which is removable and the recess is made in said male element.

 Depending on the arrangement adopted for the permanently fixed element, the "projecting" part and the "projecting" part of the removable element may be one and the same thing, or the projecting part may represent only a portion of the part protruding.

 According to a first aspect of the invention, said female element is permanently fixed to the primary leaf, said movable stop member is a bolt bolt, which bolt equips the secondary leaf, and the recess adapted to receive said bolt is made in the so-called "overflowing" part of the male element.

 Thanks to this structure, the same result is obtained as using a safety bar, but using a removable element (the male element) which is much smaller, therefore lighter, easier to handle. and of comparatively negligible size and which, moreover, allows locking both from the inside, using the lock operating wheel, as from the outside, using a key cooperating with the barrel of the bolt passing through the secondary leaf.

 In practice, the male and female elements of the keeper have a rectangular parallelepiped section.

 In a preferred embodiment of the invention, the projecting part of the male element is of a section greater than the junction part, thus determining a shoulder adapted to abut against the edge of the opening of access of the female element, when the male element is threaded there.

 The male element can take different forms to allow, in particular, different orientations of the lock, or complementary assemblies.

 Thus, the male element may be generally rectilinear, or have an L-shaped configuration in which case said protruding part is formed at least by one of the branches of the L, or have a T-shaped configuration in which case said protruding part is formed at least by the transverse branch of T.

 The recess of the projecting part, adapted to receive the bolt of the bolt, is of substantially rectangular cross section corresponding, apart from the operating clearance, to that of the bolt and this recess close to being a blind or through hole.

 When the male element is straight and the female element is mounted horizontally on the primary leaf, the recess is oriented so that it is adapted to receive a bolt moving vertically.

 To use at the same time, a female element mounted horizontally on the primary leaf and a latch mounted in such a way that its bolt moves horizontally, we will use a male element in the shape of L or T, which serve as "converters" of direction .

 It is obvious that one can also mount the female element vertically on the primary leaf and use a male L-shaped element and a bolt with vertical displacement.

 The T-shaped element adds to the functions of the generally rectilinear element, in addition to converting the bolt's direction of attack, that of a double support on either side of the recess, which is practiced in the area of junction of the two bars of the T.

 In another embodiment of the invention, the so-called "projecting" part of the male element is between two junction parts adapted to be received, each in the cavity of a female element.

 In practice, the female element is secured to the primary leaf by at least one screw passing through its cavity right through and a slot is formed in the free end of the junction part of the male element, said slot being adapted to receive said screw.

 The principle of the invention can also be applied in another way for quick and simple locking from the inside.

 According to the invention, a keeper of the aforementioned type is used which cooperates, not with a bolt bolt as a movable stop member, but with a pin or a padlock ring. In this case, the female element is fixed permanently to the secondary leaf and the recess of the male element adapted to receive said pin or said ring takes the form of a through hole made in the junction part, which hole is likely to come in alignment with two coaxial holes made in the female element.

The invention will be better understood on reading the detailed description below made with reference to the accompanying drawings in which

FIG. 1 represents a fifth embodiment of the male element according to the invention intended for the application illustrated in FIG. 9, and
- Figure it is a vertical sectional view showing an alternative implementation of the principle illustrated in Figures 9 and 18.

 If we refer to Figure 1, we see two leaves l and 2, for example, mounted flaps pivoting respectively along the axes x, x 'and, y'. The left leaf, in the figure, is shown closed and locked in this position, for example, using a latch 3 cooperating with a recess 4 made in the masonry 5. The leaf l is said to be "primary" and leaf 2 "secondary". In the closed position, the edges of the flaps 6 and 7 parallel and opposite to their respective pivot axis x, x 'and y, y' come together along the closing line z, z '.

 According to the invention, the primary leaf l is permanently provided with a female strike element 8 and a male strike element 9, while the secondary leaf is provided with a conventional lock lO which, in the case of Figure l is oriented so that its bolt it moves vertically.

 As best seen in Figure 2, the female element 8 consists of a section of rectangular parallelepiped tube, which is secured to the leaf l using a flange 12 fixed to said leaf by screws 13 and / or through bolts 14a, 14b. In all cases, the tightening nut is obviously located on the inside of the leaves when they are closed, to avoid unscrewing from the outside.

 The female element 8 determines a cavity 15 open at one end (access opening 16) and closed at its other end by a plug, not shown.

 It appears from FIG. 3 that the male element has two main parts, one and the other, of generally rectangular parallelepipedal section but one of which, 17, is of slightly smaller section than the other, 18, so that their junction defines a shoulder 19. The section of the part 17 is, apart from the necessary sliding clearance, identical to that of the female element 8, while the thickness of the shoulder 19 may correspond to that of the wall of the tube from which the female element 8 is formed. It follows, with respect to the coupling of the male and female elements, that the part 17 is said to be "junction" and that the part 18 is said to be " protruding "over its entire length L.

 As can be seen, the free end of the part 17 has a slot 2, the bottom 21 of which is orthogonal to the longitudinal axis w, w 'of the male element 9. It is understood that the location of the fixing bolt 14a of the female element 8, on the one hand, and the length of the slot 2 and of the joining part 17 on the other hand, are calculated so that, when the male element 9 is threaded into the female element 8 , the slot 2 receives said screw 14a and the shoulder 19 abuts against the edge of the access opening 16 of the female element 8. In this situation, the projecting part 18 of the male element 9 projects over a length l beyond the closing line z, z ′, and this part of length 1 is said to be "overhanging" part 22. In the embodiment of FIGS. 1 to 4, the protruding part 18 and the protruding part 22 merge (L = l) because the edge 16 of the female element 8 merges with the closing line z-z '. I1 is not the same in the embodiment of Figure 10 where the projecting portion 22d is only a fraction of the projecting portion 18d.

 In the projecting part 22 of the male element 9, a recess or passage 23 is formed, the rectangular section of which corresponds, to the operating clearance, to that of the bolt 11 of the lock.

 If we refer to FIG. 4, we can clearly see the cooperation of the female element 8, the male element 9 and the latch 1.

 The lock 1 comprises a thumb wheel 24 which makes it possible to implement the system according to the invention from inside the room equipped with the shutters. On the other face of the shutter leaf 2 is flush with the end of the barrel of the lock which can therefore be actuated from outside the room.

As indicated above, in the embodiment of Figures 1 and 4, the latch 1 is oriented so that its bolt is movable vertically. Naturally, the lock could just as easily be mounted on the leaf 2 so that its bolt It attacks the male element 9 from above rather than doing it from below.

 If one wishes to mount the lock so that its bolt is movable horizontally, one can use a male element as aue shown in Figures 5 or 6 where to designate the same characteristics we will use the same references as previously accompanied respectively by the letter a or the letter b.

In the embodiment of Figure 5, the male element 9a has a joining part 17a with its slot 2a, and an protruding part 18a, the latter having the shape of an L (reversed in the figure) The large branch of
L, possibly with all or part of the small branch of L, constitutes the projecting part 22a in which the passage 23a is formed for a bolt movable horizontally.

 In the embodiment of FIG. 6, the male element 9b comprises a joining part 17b with its a slot 2b, and an projecting part 18b, the latter having the shape of a T (lying in the figure) La transverse branch of the T, with possibly all or part of the middle branch of the T, constitutes the projecting part 22b in which the passage 23b is formed for a bolt which will also be movable horizontally. It is further provided in one of the end faces 25 of the crossbar 22b a threaded blind hole 26 adapted to receive a stud 27 which can serve as a hooking means for a tie rod, a cable, etc. anchored in masonry, to perfect the rigidity by extra precaution.

 FIG. 7 shows yet another possible embodiment for the male element which will be called 9c: this time, the protruding part 18c, with its passage 23c adapted to receive a bolt with vertical displacement, is provided, each of its ends of a junction part 17ct and 17c2. The junction part 17cri has a slot 2c, as before, but not the part 17c2. Such a male element 9c fulfills, in addition to the function of the male elements 9, 9a and 9b, that of an extension, as seen in FIG. 8.

 FIG. 8 shows this male element 9c, with its junction part 17ct able to cooperate with a female element 8 not shown, and with its passage 23c, able to cooperate with the bolt of a bolt 1 with vertical displacement. For its part, the junction part 17c2 can be received in one of the ends of a female extension module 28 of suitable section and of any length, module the other end of which can receive the junction part, for example 17b , of a male element, for example, in T 9b. The passage 23b provided in the male element 9b is, as before, able to receive the bolt of a latch 1 'with horizontal displacement. It is therefore understood that by combining the means according to the invention; one can, on the one hand, extend the projecting part of the male element and, on the other hand, counteract the burglary forces by having latches whose respective bolts act in different directions.

 Figures 9 and 1 illustrate another possibility of applying the invention. We see, in Figure 9 two leaves, id and 2d respectively, in the closed position. On the leaf 2d, a female element 8d is fixed by means of a through bolt 14d. A pair of coaxial holes 29 is made in the upper and lower walls of the female element 8d. FIG. 1 shows a male element 9d having a joining part 17d and a projecting part 18d defining between them a shoulder 19d. The joining part 17d has a through hole 3 which, when the male 9d and female 8d elements are coupled with the shoulder 19d abutted against the edge of the access opening 16d, is aligned with the holes 29.

The introduction of a pin in the holes 29 and the bore 3 blocks the male element 9d in the female element 8d, the projecting part 18d of the male element 9d opposing the spacing of the leaves id and 2d .

 As a variant to the assembly illustrated in FIGS. 9 and one can have recourse to the structure shown in FIG. 11. In this case, the female element 8e, instead of being formed from a section of tube at the walls closed as in the previous embodiments, consists of a tube whose wall opposite to that intended to be applied to the leaf 2e has as many cutouts 31 as there are screws 14e The diameter of the cutouts 31 is sufficient to allow passage a pipe wrench for screwing the nuts 32.

The female element 8e is covered with a U-shaped section 33 which has as many pairs of holes 34 as pairs of holes 29e in the female element 8e, said holes 34 being alignable with said holes 29e, therefore for a pair of 'between them with the 3rd hole of the junction part 17e of the male element. A ring 35 of canedas can be passed in each alignment of holes, and the padlock, once closed, not only blocks the male element in place but, prohibits the removal of the U-shaped profile 33 and therefore access to the nuts 32 .

 It is understood that the invention is not limited to the embodiments described and shown. In particular, instead of being screwed onto its leaf the female element could be welded there if this leaf is metallic or If a shield is interposed The same pair of leaves could be fitted with several strikes according to the invention cooperating with latches stepped, possibly acting in different directions.

 It is also understood that the element permanently fixed to its leaf could be a male element, instead of being a female element which in this case would be removable, the male element having, for example, a section similar to that of a railroad track and the female element being capable of marrying and sliding on said rail, with a part projecting / projecting beyond the closing line of the leaves.
