Description

The present invention relates to a cremone bolt, in particular intended for truck, container or other doors.

However, although more particularly intended for such applications, the present invention may also be used, in general, in all sectors of economic activity in which it is desired to be able to close and / or open doors, windows and / or others.

Currently, in the field of truck or container doors, it is known to use cremones, subject to said doors, consisting of an actuating rod terminated at its ends of bolts cooperating with strikes provided above and in - below said doors, at the level in which they are mounted.

In order to facilitate their design and manufacture, the bolts and strikes located above and below the doors are generally of the same size.

However, in order to simplify loading, the upper part of the frames is now of an increasingly low height, thus forcing to reduce the dimensions of the keeper and the bolt located above the doors, which is incompatible with the cremones currently known, except to modify their characteristics in an identical manner both in their upper part and in their lower part, at the risk of altering, in particular, their robustness.

The object of the present invention is to provide a cremone bolt which overcomes the above drawbacks and can be used to close and / or open doors mounted in frames of different dimensions below and above said doors.

Another object of the present invention is to provide a cremone bolt which has a high robustness and ensures satisfactory locking.

Another object of the present invention is to provide a cremone bolt comprising an upper lock and a lower lock, connected by an actuating rod, which makes it possible to prevent only one of the two locks is in the stop position, and this in order not to risk twisting their actuating rod.

Another object of the present invention is to provide a cremone bolt, in particular intended for the doors of a truck, container or the like, which makes it possible to make up for the slight angular offset which may appear between the doors of the body of the said trucks, containers or the like, when the latter are not parked and / or stored horizontally.

Another object of the present invention is to provide a cremone bolt whose manipulations can be carried out with a minimum of effort.

Other objects and advantages of the present invention will appear during the description which follows which is given only for information and which is not intended to limit it.

The present invention relates to a cremone bolt, in particular intended for truck, container or other doors, comprising an upper lock and a lower lock, connected by an actuating rod, said locks each consisting of a bolt, subject to said rod , cooperating with a keeper, characterized in that said lower and upper latches have different dimensions along the longitudinal axis of the rod while their dimensions are substantially identical in the directions orthogonal to said axis.

The present invention relates to a cremone bolt, in particular intended for truck, container or other doors.

However, although more particularly intended for such applications, the present invention may also be used, in general, in all areas of economic activity in which it is desired to be able to actuate doors, windows or the like.

As shown in FIG. 1, a cremone bolt 1 according to the invention comprises an upper lock 2 and a lower lock 3, connected by an actuating rod 4. Said locks 2, 3, each consist of a bolt 5, 6, subject to said rod 4, cooperating with a keeper 7, 8.

In the rest of the text, the terms “upper” and “lower” will moreover be used to qualify the elements of the locks upper 2 and lower 3 respectively.

According to the particular example of application illustrated, such cremone bolts 1 can be fitted, in particular, the rear face 9 of a truck or container. Said rear face 9 consists, for example, of a door 10, comprising two leaves 11, movable in rotation around the vertical uprights 12 of a frame 13 further comprising an upper cross member 14 and a lower cross member 15.

A cremone bolt 1 is provided, in particular, on each of the leaves 11 and cooperates with them, for example, by means of flanges 16. Said upper 2 and lower 3 locks are, for example, respectively at the level of the upper cross member 14 and of the lower cross member 15 said strikes 7 , 8 being subject to the latter and the actuating rod 4 constituting an axis of articulation common to said upper bolts 5 and lower 6.

As illustrated by the following figures, according to the invention, said upper 2 and lower 3 locks have different dimensions along the longitudinal axis 17 of the rod 4 while their dimensions are substantially identical in the directions orthogonal to said axis 17.

Such a cremone bolt can thus be fitted, for example, with doors comprising a frame whose upper crossmember is of a more limited height than the lower crossmember in order to facilitate loading.

Indeed, in the case of truck or container doors, said upper cross member generally extends from the ceiling of said truck or container to its floor and therefore reduces the opening surface defined by the leaves of the door. This is why it is now sought to reduce the dimensions of said upper cross member and of the elements added to this level.

If one refers more precisely to FIG. 2 where the position of the longitudinal axis 17 of the actuating rod 4 in the closed position is shown fictitiously, it can thus be seen that the size, identified h _gs , of the upper latch 2 in the direction of the longitudinal axis 17 is, for example, reduced compared to the size, marked h _gi , of the lower latch 3 in the same direction.

By way of nonlimiting example, one can use upper 2 and lower 3 locks whose respective dimensions h _gs and h _gi will be approximately 40 and 55 mm.

However, as mentioned above, the dimensions of the upper 2 and lower 3 locks remain substantially identical in the directions orthogonal to said longitudinal axis 17. Thus, for example, the thickness, marked e _ps , of the upper bolt 5 is substantially equal to the thickness, marked e _pi , of the lower bolt 6, in particular at the level of the axis of articulation of said bolts.

Similarly, the distance, marked I _ps , between the distal end of the upper bolt 5 and the longitudinal axis 17 of the rod 4 is substantially equal to the distance, marked I _pi , separating the distal end of the lower bolt 6 at said longitudinal axis 17.

Thanks to such characteristics, the cremone bolt according to the invention can be used on a truck having a frame provided with an upper cross member of reduced height, while retaining sufficient mechanical strength properties. It also ensures the introduction of the upper bolt 5 in the upper keeper 7, and this avoiding having to make tedious adjustments at the time of assembly.

However, according to the embodiment shown, said bolts 5; 6 are in the form of a spout 18, 19 each provided with a longitudinal axis 20, 21, substantially perpendicular to said longitudinal axis 17 of the rod 4, and a transverse axis 22, 23, substantially perpendicular to said longitudinal axis 17 of the rod 4 and to said longitudinal axis 20, 21 of said bolts 5, 6.

In known manner, said spout 18, 19 comprises a body 24, 25, the orthogonal projection of which on the plane defined by the longitudinal axis 17 of the rod 4 and the longitudinal axis 20, 21 of said bolts 5, 6, said plane V, has a substantially trapezoidal isosceles shape symmetrical with respect to said longitudinal axis 20, 21 of said bolts 5, 6. Said beaks 18, 19, are further provided, for example, at their distal end, with a nose 26, 27 round.

In order to facilitate the introduction of said bolts 5, 6 into said strikes 7, 8 and / or to allow the taking up of any play, the angles, marked α _ps and α _pi , between the sides of the trapezoid formed by said projection orthogonal to the plane V of the body 24, 25 of said spouts 18, 19 are substantially identical on the bolt 5 of the upper bolt 2 and on the bolt 6 of the lower bolt 3. The same reduction ratio is not thus uniformly adopted in order to pass dimensions, along the longitudinal axis 17 of the rod actuation 4, from the lower latch 3 to the lower latch 2.

FIG. 8 illustrates, more particularly the corresponding shape of the beak 18, 19 of the upper 5 and lower 6 bolts 6. It can thus be seen, as mentioned above, that the angles α _pi and α _ps are equal as are their longitudinal dimensions I _ls and I _li .

It can also be seen that the orthogonal projection of the noses 26, 27 of said spouts 18, 19, on the plane V, has a greater curvature on the bolt 5 of the upper bolt 2 than on the lower bolt 6.

However, we can use, for example, bolts 5, 6 whose bodies 24, 25 are formed of a truncated cone of substantially elliptical section, extended by noses 26, 27 rounded, tangent to said truncated cone.

In this case, the conservation of the same angle α _pi and α _ps between the upper bolt and the lower bolt causes, in particular, a modification of their taper, the section of the beak 18 of the upper bolt 5 being substantially more round than the section of the lower bolt beak 6.

By way of nonlimiting example, it is possible to choose angles α _pi and α _ps between the sides of the trapezoids formed by the orthogonal projection of the bodies 24, 25 of the spouts 18, 19 on the plane V of approximately 30 °. The length between the distal end of said bolts 5, 6 and the longitudinal axis 17 of the rod 4 may in turn be, in particular, 49 mm.

However, if we refer again to Figures 2 to 4, according to the illustrated embodiment, said strikes 7, 8 consist, in particular, of a flange 28, 29, subject to a sole 30, 31. As previously mentioned, according to the invention, the lengths I _bs and I _{bf of} said flanges 28, 29 along the longitudinal axis 36, 37 of said strikes 7, 8 are identical as well as the distances I _as and I _af between the proximal end said upper flanges 28 and lower 29, on the one hand, and said axis 17 on the other hand.

Similarly, as shown in FIGS. 2 and 4, the thickness e _ss of the sole 30 of the upper strike 7 and the thickness e _si of the sole 31 of the lower strike 8 are identical as well as the dimensions, respectively marked e _bs and e _bi , flanges 28, 29 of upper strike 7 and lower 8, in the same direction.

According to the illustrated embodiment, said bolts 5, 6 closely match the inside contour of the flange 28, 29 of said strikes 7, 8 in the closed position. Thus, as for said bolts 5, 6, the orthogonal projection on the plane V of the sides of the flanges 28 of the upper strike 7 and of the sides of the flange 29 of the lower strike 8 being, in particular, respectively inclined towards one other at an angle marked α _gs and α _gi , said angles α _gi and α _gs are, for example, equal and identical to the angles α _pi and α _ps .

As shown, said strikes 7, 8 comprise, possibly, in addition, a boss 32, 33 able to cooperate with a groove 34, 35 provided at the rear of said bolts 5, 6, the angular dimensions in the plane V, in particular identified α _bone and α _oi of the boss 32 of the keeper 7 of the upper lock 2 and of the boss 33 of the keeper 8 of the lower lock 3 being, for example, substantially identical, and this also in the vicinity of said plane V, in the planes parallel to this last.

By plane V, it is necessary here to understand the plane defined by the longitudinal axis 17 of the actuating rod 4 and the longitudinal axis 36, 37 of the keepers 7, 8, of the upper 2 and lower 3 locks, corresponding to said longitudinal axis 20, 21 of the bolts 5, 6 with closure.

The simultaneous cooperation of said bosses 32, 33 and said grooves 34, 35 makes it possible, in particular, to facilitate the introduction of the bolts 5, 6 into the keepers 7, 8.

That said, the cremone bolt according to the invention further comprises, optionally, a handle 38 in the extension of the bolt 6 of the lower lock 3, said handle 38 and said bolt 6 of the lower lock 3 being diametrically opposite with respect to the rod 4.

As shown in FIGS. 2 and 5, said handle 38 has, in particular, slots 39, 40, able to cooperate with a locking member, not shown, and / or a tongue 41, capable of allowing padlocking of said handle 38, provided at said striker 8 of the lower lock 3.

Furthermore, the bolts 5, 6 also have, optionally, shoulders 42, 43, capable of cooperating with said flanges 28, 29 and delimiting their insertion into the latter.

Naturally, other implementations, within the reach of those skilled in the art, could have been envisaged without departing from the scope of the present invention.
