Description

The present invention relates to a pivot door of the type comprising at at least one leaf on which two rods are mounted in parallel by means of rods. The invention applies in particular to a metal door intended to be mounted on a ship or infrastructure ashore.

Metal ship doors are generally designed to be watertight in relation to the frames on which they are respectively mounted. For this reason, provision has been made to provide these doors with locking in the closed position which are such that said doors can remain closed even in the event of accidental overpressure, so as to avoid water ingress or air in the corresponding rooms.

European patent document EP-B-552 505 presents a system for lock which is supposed to reliably seal a door ship. According to a preferred embodiment which is described in this document in relationship with Fig. 3, this locking system is notably characterized by a high number of latches (six in number in the example shown), so that effectively guarantee the aforementioned locking. These latches are designed to come in stop against internal walls of the frame on which the door is mounted.

Said system essentially consists of two mounted rods vertically on a door leaf by means of said latches, which are respectively pivotally mounted on said leaf and articulated on each rod. These two rods are connected together and at their upper and lower ends in look by two horizontal arms, on which other latches are articulated. Each arm is connected by its ends to the corresponding ends of said rods, this by means of two articulated links on the rods. As for each rod, it is pivotally mounted on said leaf.

A control handle intended to move, via a link to which it is connected, said rods and, therefore, rotate said latches around of their respective pivots so as to disengage them from said frame, is mounted in link with the rod furthest from the leaf joints.

A major drawback of such a locking system lies in the complexity of its manufacturing process.

The object of the present invention is to remedy this drawback, by proposing a pivoting door of the type comprising at least one leaf on which are two rods mounted in parallel by connecting rods, at least one of which of them forms a latch for locking said door in the closed position, said rods being pivotally mounted on said leaf and on said rods, which has security guarantees in the locked position, while being maneuverable without involving the exercise of a significant effort.

To this end, a door according to the invention is characterized in that said rods are connected together at their ends two by two opposite by two connecting rods, each of which is pivotally mounted, on the one hand, on said leaf and, on the other hand, on two ends opposite said rods.

According to another characteristic of the invention, at least one of said connecting rods is provided to constitute a locking means in position of closing said door.

According to another characteristic of the invention, each rod has two end parts bent on the same side of said rod and intended to be mounted by pivots on said connecting rods, said pivots being mounted in a diametrically opposite manner with respect to the fixing pivots of the said connecting rods on said or each leaf.

According to an exemplary embodiment of the invention, at least one of said rods is also provided to constitute, by one of its ends, a means locking in the closed position of said door.

According to another characteristic of the invention, a control handle pivotally mounted, on the one hand, on the pivot for fixing to the leaf of one of the latches, which is articulated on the rod adjacent to the pivoting edge of said leaf and, on the other part, on the pivot of articulation of said latch to said rod, is provided for control the lifting of a control rod to which it is articulated between said pivots, so as to move said rod in the pivoting direction of said handle and the other rod in an opposite direction, via said connecting rods, and thus rotate the latches relative to said leaf.

According to an alternative embodiment of the invention, said door comprises two leaves, one of which is provided with at least one latch rod and designed to come into abutment against an element of the other leaf, in the position of locking of said leaves.

Fig. 6 is a partial sectional view along the plane VI-VI of FIG. 5 of a door according to said second mode, and

Fig. 7 is a detail and front view of the members provided for controlling said door according to a second embodiment in the open and closed position.

As shown in FIG. 1, door 1 according to a first mode of embodiment of the invention is intended to be mounted on a frame 2 by hinges 3. The door 1 essentially consists of a leaf 4 and means 5 mounted on said leaf 4 and provided for locking the door 1 in the locked position in the frame 2.

The locking means 5 comprise two vertical rods 6 and 7 movable and identical which are mounted on leaf 4 by means of first and second latches 8, 8 'and 9, 9'. As can be seen in the detail view of FIG. 2 the locking means 5 are contained in a plane parallel to the plane of the leaf 4.

The locking means 5 also include members 10 provided for control the passage of latches 8, 8 'and 9, 9' from a locking position (shown in Fig. 1) in an unlocked position (shown in Fig. 4), or vice versa. These members 10 are connected to the rod 6 which is furthest from said hinges 3.

The latches 8, 8 'and 9, 9' are pivotally mounted relative to the leaf 4, and they are each designed to come into abutment against a sloping part 2 'of a housing internal 11 to said frame 2 (the slope of this part 2 'is formed in the direction door vertical 1).

Each first latch 8, 8 ', or connecting latch, is pivotally mounted by relative to leaf 4 by means of a pivot 12 fixed to said leaf 4. The there are two connecting latches 8 and 8 ', and they are mounted respectively proximity of the upper edge and the lower edge of the leaf 4, in the longitudinal axis of symmetry of the latter. Each link latch 8, 8 'has, in two of its ends, two oblong holes 13 and 14 of linear shape which are located at equal distance from the fixed pivot 12, and which are diametrically opposite in the direction of their length relative to said pivot 12.

Each rod 6, 7 has at each of its ends a pivot 15, 16 which is movable relative to leaf 4 and which is mounted in one of the oblong holes 13, 14.

The two connecting latches 8 and 8 ′ are thus provided for connecting the two rods 6 and 7.

Each link latch 8, 8 'has a third end 17 which is intended to engage in the corresponding housing 11. As can be seen from the Fig. 1, the ends 13, 14 and 17 of each latch 8, 8 'give it substantially a form of λ whose apex is formed by said end 13.

Each second latch 9, 9 'is pivotally mounted relative to the leaf 4 by via a pivot 18, 19, 20 fixed on said leaf 4. Each rod 6 (respectively 7) is articulated on the same number of second latches 9 (respectively 9 '), by pivots 21, 22 and 23 movable relative to the leaf 4. As can be seen in Fig. 1, each fixed pivot 18, 19, 20 is mounted between the longitudinal edge 24, 25 of the leaf 4 and the rod 6, 7 which is mounted adjacent to said edge 24, 25.

Each second latch 9, 9 'has a unique shape, and it is for example consisting, on the one hand, of a first linear part 26 intended to be crossed by one of the movable pivots 21, 22 and 23 and, on the other hand, of a second part also linear 27 intended to be crossed by one of the fixed pivots 18, 19 and 20 and forming a obtuse angle with the previous one.

In this embodiment, the major part 28 of each rod 6, 7, or middle part, has a linear shape and is intended to be found vertically mounted. Each rod 6, 7 further comprises two end parts linear and identical 29 which diverge from each other on the same side of said central part 28 and which terminate in said movable pivots 15 and 16.

In the example of FIG. 1, each rod 6, 7 is articulated on three seconds latches 9, 9 ', by means of said movable pivots 21, 22 and 23 which are respectively mounted in the middle and at the two ends of said middle part 28. As for the fixed pivots 18, 19 and 20 mounted opposite the same rod 6, 7, they are aligned in a vertical direction.

As can be seen in Fig. 1, the movable pivots 21, 22 and 23 and the fixed pivots 18, 19 and 20 relating to the same rod 6, 7 constitute the vertices of a deformable parallelogram. One of the long sides of this attached parallelogram said fixed pivots 18, 19 and 20, and it is itself fixed relative to leaf 4.

The control members 10 of the rods 6 and 7 are shown in detail in Figs. 2 and 3.

They have a handle 30 in the form of a sleeve which is mounted pivotable relative to leaf 4 by means of fixed pivot 18 which is adjacent to the rod 6. The handle 30 is further mounted on the movable pivot 21 passing through the midpoint of the rod 6 via an oblong hole 31 (see Fig. 2) of which said handle 30 is provided.

As can be seen in Fig. 2, said oblong hole 31 has a shape of an arc of a circle which is centered on the fixed pivot 18 forming the axis of rotation of said handle 30. The latter, the rod 6 and the median latch 9 relative to the latter are thus all three mounted on said movable pivot 21. In the locked position of door 1 illustrated in FIG. 2, the upper end of the oblong hole 31 is located at contact of said pivot 21.

Referring to Fig 2, the handle 30 has a bent portion 32 which is intended to be crossed by said pivots 18 and 21.

In addition, said control members 10 comprise a link 33 which is pivotally mounted, at one of its ends, on said handle 30 via a pivot 34 mounted on the handle 30 between said central pivots 18 and 21. The connecting rod 33 is connected at its other end to the rod 6 by means of a pivot 35 which comprises said rod 6. The pivot 35 is mounted above said central pivot 21 and, in this exemplary embodiment, the distance which separates it from the latter is substantially equal to a third of the distance provided between said central pivot 21 of said upper pivot 22.

As shown in FIG. 3, the means 5 provided for blocking the door 1 in the locking position, as just described, are mounted on the leaf 4 on the same side of it. From the handle 30 which is the most distant from the plane containing the leaf 4 and up to the latter, are successively mounted on said handle 30 the link 33 via the pivot 34, the median latch 9 via the pivots 18 and 21, and the rod 6 via said movable pivot 21.

The handle 30 is extended on the other side of the leaf 4 by another handle 36, which is mounted on said fixed pivot 18 via an angle bend right which it has.

There is shown in FIG. 3 a seal 37 which is mounted on the periphery of one side of the leaf 4 and which is intended to come against the frame 2 of the door 1, when the latter is controlled in the locking position illustrated by the Fig. 3.

It will be noted that the inclination of the above-mentioned sloping parts 2 ′ which are respectively provided for receiving in abutment said latches 8, 8 ', 9 and 9' is provided to allow the tightening of the door 1 by crushing said seal 37, when said door 1 is locked in the closed position.

It will also be noted that this tightening of the door 1 in the closed position is made possible by a slight translation of the door 1 in its hinges 3, this in a direction perpendicular to the plane of the frame 2 and in the direction of the compression of said seal 37.

The door 1 according to this first embodiment of the invention operates from the following way.

When it is desired to pass it from the locking position of FIG. 1 to the unlocking position shown in FIG. 4, the handle 30 (or the other handle 36, depending on whether one is on one side or the other of the door 1) up around the fixed pivot 18, so that the lower end of the hole oblong 31 of the handle 30 comes into contact with the movable pivot 21, which is mounted integral with said handle 30.

This pivoting of the handle 30 around the pivot 18 has the effect of displacing upward the lower pivot 34 and, therefore, the upper pivot 35 of the rod 33. This results in an uplift of the rod 6 according to a movement of vertical translation, as shown in FIG. 4.

The lifting of the rod 6 simultaneously causes the pivoting of the three latches 9 in the direction of arrow A (Fig. 1 and 2), around their respective axes constituted by the three pivots 18, 19 and 20. This triple pivoting results in release, opposite the rod 6, the second part 27 of each latch 9 of the part steep 2 'of the door frame 2 against which it abutted, inside the housing 11 corresponding. This release of the latches 9 adjacent to the rod 6 is shown in Fig. 4.

The above-mentioned lifting of the rod 6 also has the effect. to raise simultaneously the end of the upper link latch 8 to which it is connected, by the upward force exerted by the pivot 15 of the rod 6 on the upper edge of the oblong hole 13 constituting said end.

This lifting of the end 13 of the connecting latch 8 is accompanied by a lowering in proportion to the opposite end 14 of said latch 8. This lowering results in releasing the third end 17 of the latch 8 from the housing 11. The pivoting movement of the latch 8 around the fixed pivot 12 is illustrated by the arrow B of Fig. 1.

We can see in Figs. 1 and 4 as the pivot 15 which is integral with the rod 6 passes from a first position (Fig. 1) where it is between the two ends of the hole oblong 13, at a second position where it abuts against the end of said hole 13 which is furthest from the fixed pivot 12 (Fig. 4). In the same way, the pivot 16 which is integral with the rod 7 passes from a first intermediate position between the ends of the oblong hole 14, at a second position where it abuts against the end of said hole 14 furthest from the pivot 12.

This pivoting of the latch 8 generates a lowering of the rod 7 according to a substantially vertical direction from a height identical to the lifting height of the rod 6. This results in a pivoting of the three latches 9 'to which the rod 7 in the direction of arrow C (Fig. 1), so that the second part 27 of each latch 9 'emerges from the housing 11 provided to receive it.

The aforementioned lifting of the rod 6 and the concomitant lowering of the rod 7 have the effect of rotating the lower connecting latch 8 'in the direction of arrow D (Fig. 1), by the upward and downward forces respectively exerted by the pivots 15 and 16 on the oblong holes 13 and 14 of said latch 8 '. This pivoting results in releasing said third end 17 of latch 8 'from corresponding housing 11.

As for the upper latch 8, we see in FIG. 4 that the pivots lower 15 and 16 occupy extreme positions in the oblong holes 13 and 14 8 'lower latch.

Consequently, it results from the upward actuation of the handle 30 that all latches 8, 8 'and 9, 9' of door 1 occupy a position which is such that said door 1 can be opened. To do this, a pushing force is exerted on the handle 30 (or pulling on the other handle 36) while holding the latter in raised position.

Note that during the aforementioned unlocking operation of door 1, the release of the latches 8, 8 ′, 9 and 9 ′ of the sloping portions 2 ′ results in the fact that the seal 37 ceases to be compressed between said door 1 and the frame 2. It results in a slight translational movement of the door 1 in its hinges in the direction of expansion of said joint 37.

When you want to move door 1 from the unlocking position of Fig. 4 in the locking position of FIG. 1, the handle 30 (or the handle 36) downwards relative to pivot 18, as shown in FIG. 1 by the arrow F, so that the upper end of the oblong hole 31 comes into contact of the pivot 21. This lowering of the handle 30 has the effect of lowering the pivot upper 35 of the rod 33 and, therefore, the rod 6. Unlike what has just been described concerning the actuation of door 1 in the position of unlocking, this lowering of the rod 6 is accompanied by a lifting rod 7 in the same proportion, and this results in a pivoting of the latches 8, 8 'and 9, 9' in opposite directions to those indicated by the arrows A, B, C and D.

In this first embodiment of the invention, it will be noted that each longitudinal rod 6 or 7 has two end parts 29 which are bent by relative to the rest of said rod 6 or 7 towards the other rod 7 or 6, such so that two adjacent end portions 29 belonging respectively to said rods 6 and 7 have their end pivots 15 and 16 which are mounted nearby immediate from each other. This makes it possible to use a single connection means of the type connecting rod such as the latch 8, 8 'mentioned above, which means is provided for connecting together said pivots 15 and 16 opposite.

According to an advantageous characteristic of the invention, said connecting means 8, 8 ′ is also provided for engaging against said steep part 2 ′ of the frame 2, in the manner of each latch 9, 9 '.

Note that the rods 6 and 7 can be easily moved one by relative to the other by actuation of the handle 30 (or 36), due to the moment of relatively reduced inertia which characterizes each connecting latch 8, 8 'and which facilitates the pivoting of these. Therefore, door 1 has the advantage of being able to be controlled in the locked and unlocked position by force exerted on the handle 30 (or 36) which is of reduced intensity.

For the following description of a second embodiment of the invention, we used numerical references increased by 200 for the designation elements having a structure identical or similar to that of the elements previously described.

A door 200 according to a second embodiment of the invention is shown in FIG. 5. It has two leaves 204a and 204b which are respectively pivotally mounted on the two uprights 202a and 202b of a frame 202 by joints 203. The door 200 also includes means 205 mounted on each leaf 204a, 204b and designed to lock the door 200 in position lock in the frame 202.

In the example of this third embodiment which is shown in the Fig. 5, the locking means 205 with which each leaf 204a, 204b is provided are contained in a plane parallel to that of said leaf 204a, 204b, and they comprise two rods 206 and 207 of different shapes. Rods 206 and 207 of the same leaf 204a, 204b are mounted on said leaf 204a, 204b parallel to the axis of the joints 203 thereof, by means of first and second latches 208, 208 ', 209, 209' of the aforementioned type and also of a third latch 250 which is different precedents.

As for the members 210 provided for controlling the passage of said latches 208, 208 ', 209, 209', 250 from a locking position to a unlocking, or vice versa, they are shown in detail in Figs. 6 and 7.

These members 210 are mounted on the rod 206 of each leaf 204a, 204b which is furthest from said joints 203. As can be seen in Figs. 6 and 7, the handle 230a, 230b and the link 233 of said control members 210 which are mounted on each leaf 204a, 204b have a structure identical to that of the same constituents of the control members 10, according to the first mode of production. They will therefore not be the subject of a particular description.

The rod 207 of a leaf 204a, 204b which is adjacent to the joints 203 of it has a structure similar to that of the rods 6 and 7 of the first mode of achievement. The middle part 228 of said rod 207 is connected to several second latches 209 ′ (also three in number in the example in FIG. 5). The upper and lower parts 229 which each extend said middle part 228 on the same side of the latter are respectively connected to the first latches 208 and 208 'by pivots 216.

For each leaf 204a, 204b, the rod 206 which is the farthest of said joints 203 has a middle part 251 similar to said part median 228. The rod 206 also comprises an upper part 252 and a lower part 253 which extend respectively upwards and downwards said middle part 251, on the same side of the latter.

Regarding one of the leaves 204a, said middle part 251 of the rod 206 is connected to several rods 254 (three in number in this example) by a pivot median 221a and two end pivots 222a and 223a, respectively. Each link 254 is provided to guide the rod 206 in its movement, during actuation of the control members 210.

Regarding the other leaf 204b, said middle part 251 of the rod 206 is connected to several second latches 209 (three in number in this example) by pivots 221b, 222b and 223b which are mounted opposite the pivots 221a, 222a and 223a of leaf 204a. As can be seen in FIG. 6, each second latch 209 is intended to abut against a sloping part 204c integral with the other flying 204a.

As for the first embodiment, it will be noted that the inclination of this sloping part 204c allows the tightening of the door 200 in the position of closing, by crushing the seal 237 which surrounds said leaf 204b.

The upper part 252 of the rod 206 is intended, on the one hand, to be connected to said third latch 250 by a pivot 255 and, on the other hand, to be connected to the first upper latch 208 by a pivot 215. Said pivots 215 and 255 define a triangle with the upper pivot 222. The upper vertex of this triangle is constituted by the pivot 255, which is for example intended to evolve in a hole oblong curved 256 that comprises said part 252. As can be seen in FIG. 5 the curvature of the oblong hole 256 is directed towards a fixed pivot 257 with respect to which the latch 250 is provided to pivot.

The lower part 253 of the rod 206 consists of two arms 258 and 259 which extend downward said middle portion 251, respectively in the same direction and at an acute angle with respect to it, so that said arm 259 departs from the middle part 251 on the same side as said upper part 253. The arm 258 is provided to cooperate in the manner of a latch with a housing 211 door frame 202, while arm 259 is intended to be connected to the first latch lower 208 'by a pivot 215.

Also shown in Figs. 5 and 6 of the means 260 provided for ensuring mutual overlapping of the non-articulated edges 224 of the leaves 204a and 204b, so as to seal the door 200 in the closed position.

A door 200 according to this third embodiment of the invention works as follows.

When you want to unlock door 200, you first lift the handle 230a for leaf 204a, then the handle 230b for leaf 204b (see arrow O), so as to move the upper pivot 235 of each link 233 upwards. As with the first embodiment, this results in an uplift of each rod 6, which is accompanied by a lowering of each rod 7 by through each first latch 208, 208 '.

This displacement in the opposite direction of the rods 6 and 7 in a direction vertical has the effect of rotating the rods 254 of the leaf 204a, the second latches 209 and the third latch 250 of leaf 204b in the direction indicated by the arrows E. This movement also has the effect of rotating the first latches 208, 208 ′ of each leaf 204a, 204b in the direction indicated by the arrows F and G, respectively, as well as the second latches 209 'of said leaves 204a and 204b in the direction of the arrows H.

During these displacements of the rods 6 and 7 and of the latches 208, 208 ′, 209, 209 ', 250, the arm 258 of the lower part 253 relating to each rod 6 is gradually releases housing 211 provided to receive its end, due the lifting of said rod 6. In addition, each second latch 209 of the leaf 204b emerges from the shoulder 204c provided to receive it, due to its pivoting.

As for each third latch 250, it will be noted that the pivot 255 from which it is solidary evolves inside the oblong hole 256 when moving upwards each rod 6. This latch 250 and the other latches 208, 208 'and 209 are released also gradually housing 211 respectively provided to keep them in stop, and the door 200 is finally in the unlocked position.

To open the door 200, a pushing force is first exerted on the handle 230b of leaf 204b (or pull on the other handle 236b of the same beating 204b), while maintaining said handle 230b (or 236b) in the raised position. Then we push the handle 230a of the other leaf 204a (or we pull on the handle 236a) in the raised position. This opening sequence is imposed by covering the leaf 204a with the leaf 204b (see Fig. 6).

As for the first embodiment, it will be noted that a door 200 has the advantage of being able to be controlled in the locking position and unlocking by means of a force exerted on the control members 110 or 210 which is of reduced intensity, due to the relatively reduced moment of inertia which characterizes each connecting latch 208, 208 ′ and which facilitates the pivoting thereof.

It will also be noted that a door 1, 200 according to the present invention is not not limited to the exemplary embodiments which have just been described, but that it could include a different number of second latches 9, 9 ', 209, 209', in particular. Of more, the structure and shape of these, as well as those of the connecting latches 8, 8 ', 208, 208', could be the subject of other alternative embodiments.
