Lock box equipped with an anti-panic plate and a European type half cylinder.

The invention belongs to the field of locksmithing.

The present invention relates more precisely to a lock box equipped with an anti-panic plate.

In a certain number of professional premises, the regulation imposes, for security reasons, that the lock boxes installed on the doors of these premises are equipped with an anti-panic plate. An anti-panic plate of this type is a plate or a lever that allows the door to be opened, without having to maneuver the lock with a key.

A particular example of application refers to electrical or semi-private transformer stations or stations that are premises connected to the electricity grid, in particular high voltage, and contain devices that allow modifying and generally lowering the voltage of the electric current with a view to distribution to

end users

The access doors to these transformer stations are equipped with lock boxes, so that it is possible to lock them to prevent entry to any unauthorized person and avoid accidents due to

electrocution.

The maintenance operations involved in these transformer stations have the key and can enter. However, to the extent that they are not authorized EDF agents, the regulation requires that the lock boxes be equipped with an anti-panic plate on the inside of the premises so that in case of an accident, in particular burns in the hands, the maintenance operator can open the door from the Interior, simply pushing the plate with the body and without having to manipulate a key.

These lockable boxes with plates whose cylinder (or cylinder) is of the round cylinder type are already known in the state of the art.

A lock box of this type is for example known from FR 1 280 695 A.

As a reminder, remember now that the cylinder is the device that allows you to move the lock latch thanks to a key.

This type of cylinder is very specific, only a few manufacturers sell it and therefore it is expensive. In addition, in case of loss of a key, its renewal is also expensive and complex. A door maneuver mechanism of the anti-panic type with a European type cylinder is known from WO 02/25041 A1.

An object of the invention is to provide an alternative to a lock box equipped with a plate.

To this end, the invention relates to a lock box equipped with an anti-panic plate.

According to the Invention, this lock box comprises a cabinet, sealed by a cover called "cover", a latch body mounted inside the cabinet so that it can slide axially therein, and a European type half cylinder , this latch body comprising a bottom, two longitudinal sides and is terminated at one of its ends by a rear partition and at its other end by a latch, being a spring, called a "latch spring", mounted between the rear partition of the cabinet and the rear partition of the latch body, this spring permanently tending to move the latch body into an active position, in which the latch protrudes from the closet, each of the two longitudinal sides of said latch body being pierced by a opening, these two coaxial openings and the bottom of the latch body being perforated by a recess arranged near these two openings, said half cylinder being of European type mounted transversely to said box and positioned transversely to said emptying, so that when operated by a key, its blade can be introduced into one or other of these openings and cause the axial displacement of the latch body, against the force exerted by said latch spring, until it is taken to a passive position, in which the latch is inside the cabinet.

According to other advantageous and non-limiting characteristics of the invention, considered alone or in combination:

- said anti-panic plate comprises a handle equipped with a pusher and with an L-piece, said L-piece comprising an inclined ramp and a stop stop, this handle being pivotally mounted at one of its ends with respect to said cabinet, being a spring, called "plate spring" mounted between this handle and the outer face of the bottom of said cabinet, the latch body comprises a stud fixed between its two longitudinal sides, perpendicularly to these, permanently extending the plate spring to separate said closet handle, so that said anti plate

The cabinet 3 will be described in more detail below, referring to Figures 3 and 8.

The cabinet 3 comprises a rectangular bottom 30 or palastro, bordered on its four sides by partitions that extend at a right angle at a small height, namely two longitudinal partitions 31 and 32, a rear partition 33 and an opposite front partition 34 or "head".

The blade 30 has a medium longitudinal axis X-X1.

The head 34 has in its central part a rectangular recess 341, through which the end of the latch 5 can be displaced in translation. Two recesses 342, 343 are made on either side of the recess 341. They extend parallel to the flange of head 34. Your paper will be explained below.

The blade 30 is further perforated by a groove 300 and a bean-shaped hole 301, aligned along the longitudinal axis X-X ', the hole 301 being closer to the head 34.

The plate 30 is also perforated, for example in its four corners, by holes 302 that allow its assembly with the cover 4.

The longitudinal partitions 31 and 32 are perforated, near the rear partition 33, by a hole 311, respectively 321 that allows the fixing of the cover 4 by means of screws (visible only in figures 8 to 10) and near the head 34, by two holes 312, 313, respectively 322, 323.

The holes 312 and 322 are coaxial and allow the passage of an element (not shown in the figures) for fixing the half cylinder 6.

Finally, holes 313 and 323, also coaxial, allow the passage of a pivot shaft of the handle 7 with respect to the cabinet 3.

The cover 4 will be described in more detail below, with reference to Figure 4.

It is composed of a sheet of small thickness of generally rectangular shape and has two longitudinal edges 41, respectively 42 and two shorter edges, namely a rear edge 43 and a leading edge 44.

The cover 4 has an average longitudinal axis X1-X'1.

The cover 4 has a notch or cut 441, rectangular in shape that leads to the height of the leading edge 44. The leading edge 44 is clipped so that it has two small tongues 442 and 443, on either side of the cut 441. When the cover 4 is assembled with the cabinet 3, these tabs 442, 443 are respectively received in the recesses 342 and 343 of the head 34. In addition, the cutout 441 is in front of the recess 341.

The cover 4 also has several holes 402, preferably one in each of its four angles. When the cover 4 is assembled with the assembly 3, these holes 402 allow the passage of fixing elements, such as screws (not shown in the figures). They are placed in front of holes 302 of cabinet 3.

The face 40 of the palette 4 is called "internal face" since it is located in front of the interior of the cabinet 3 when the pallet 4 and this arm are in the assembled position.

The longitudinal edges 41 and 42 of the blade 4 are equipped, near the rear edge 43, with a wing 410, respectively 420, constituted by a rectangular shaped sheet portion folded at a right angle to the inner face 40. These two wings 410, 420 are each perforated by a hole 411, respectively 421.

The distance between the two outer faces of the wings 410 and 420 is slightly less than the distance between the inner faces of the longitudinal partitions 31 and 32 of the cabinet 3, so that these wings 410, 420 can be inserted inside of the cabinet 3 when the latter is assembled with the pallet 4. In this assembly position, the holes 311, 411, 321 and 421 are aligned and allow the assembly by means of two screws 315, 325, visible only in Figures 8 to 10, and of nuts not shown in the figures.

The cover 4 is perforated by a groove 400 and a hole 401 in the form of beans, aligned along the axis X1-X'1. Holes 301 and 401 are coaxial when cover 4 and cabinet 3 are assembled. In this position, axes X-X 'and X1-X'1 are parallel.

The cover 4 has a C-cut between the two wings 410 and 420, symmetrical with respect to the axis X1-X'1. The sheet is folded at right angles to the inner face 40, so that a rectangular opening 403 is defined, bordered by a leg 404 perpendicular to the plane of the cover 4 and perpendicular to the wings 410, 420. Its paper will be described. below.

Finally, a reinforcement 45 is applied by welding on the inner face 40 of the cover. This reinforcement 45 is made from a rectangular sheet metal sheet, folded twice so that it has a U-section with right angles. Therefore, it has a central area 450 and two lateral wings 451 and 452, each perforated by a hole 453, respectively 454.

The two wings 451, 452 extend to either side of the oblong part of the bean-shaped hole 401.

The reinforcement 45 allows to maintain a constant distance between the cabinet 3 and the cover 4, when these two elements are assembled, and also serves to fix the half cylinder 6 as will be described below.

The latch 5 will now be described in more detail, referring to figures 6 and 7.

This piece has been obtained from a sheet with a substantially rectangular shape whose longitudinal sides are much longer than the transverse sides, this sheet having been folded longitudinally twice, so that it has a U-shaped cross section with right angles .

This latch 5 thus presents a bottom 50 and two longitudinal sides 51, 52.

It has a longitudinal axis X2-X'2.

The latch body 5 is closed at its rear end by a rear partition 53 that extends perpendicularly to the bottom 50 and to both sides 51 and 52, and which is slightly retracted with respect to the rear free ends of these sides 51 and 52. A small cylindrical column 530 is fixed, for example by screwing, perpendicularly to this rear partition 53, so that it protrudes out of the latch body 5.

The front end 54 of the latch body 5 is preferably inclined in a bevel, so that it forms a latch known to the person skilled in the art with the designation of "half-turn latch".

When the different constituent elements of the lock box 1 are assembled, the half-turn latch 54 protrudes out of the box by the emptying 341 of the head and moves when the closing of the door takes place to automatically engage in the solidarity lock to the door frame, thus guaranteeing its immobilization.

This latch 54 could also be a sleeping latch with a rectangular section, but which does not guarantee automatic closing.

The bottom 50 is not solid in the entire length of the latch body 5. It has, in its central part, approximately one third of its length, a rectangular recess 55.

The rear part of the bottom 50, which extends from the rear partition 53, has a longitudinal groove 58 leading to the recess 55.

Finally, the longitudinal sides 51 and 52 of the latch body 5 are perforated by a hole 511, respectively 521 and by an opening 512, respectively 522.

Holes 511 and 521 are circular, coaxial and perpendicular to the X2-X'2 axis.

The openings 512 and 522 are also coaxial and symmetrical with respect to the axis X2-X'2. They have a square portion that extends in the direction of the half-spindle 54 by an oblong-shaped portion.

As can be seen in Figures 8 to 10, the holes 511 and 521 allow the fixing of a stud 56 that extends perpendicularly to the longitudinal axis X2-X'2 of the latch body 5.

On the other hand, when the latch body 5 is inserted into the cabinet 3, a spring 57, for example a helical spring called "latch spring" is mounted and maintained between the rear side 33 of the cabinet 3 and the small column 530 around of which it is fixed. This spring 57 is visible only in Figures 1 and 8. It permanently tends to move the latch body 5 in the "active" position where the half-tooth 54 is outside the cabinet 3, as shown in Figure 8. In this position , the face of the rear partition 53 opposite to that carried by the small column 530 comes to rest against the leg 404.

Finally, sides 51 and 52 have a step 513 near the front end 54 (semi-spike),

respectively 523. When the latch body 5 is mounted in the box, the notch 441 of the cover 4 serves

to guide it and also serves as a rear end stop of the latch body 5. The steps 513, 523 run against the bottom of the notch 441.

The lock box according to the invention is equipped with a device 6, known to the person skilled in the art with the name of "European semi-cylinder", and which, thanks to a key, allows axially displacing the half-spindle 54 to remove it from the lock. And open the door.

The "European" designation corresponds to a bean-shaped cylinder. The name "semi-cylinder" designates the fact that the lock can only be operated by only one side of the door, in this case by the outer side of the door.

The half cylinder 6 is mounted inside the box 1 so that it crosses the hole 401 of the cover 4, the

emptying 55 of the latch body 5, and finally it emerges at the height of the bean-shaped hole 301 of the cabinet 3.

It is held in position by a screw (not shown in the figures) mounted so that it either crosses the hole 322, the oblong part of the hole 522, the hole 454 of the reinforcement 45 of the cover and penetrates into the base of the semi-cylinder 6 , or through hole 312, the oblong part of hole 512, hole 453 and penetrate the base of half cylinder 6.

The European semi-cylinder 6 has a hole 61 for inserting the key, which allows a rotor 62 to be dragged inside a stator not visible in the figures. The rotation of this rotor 62 causes, in a manner known to the person skilled in the art, the displacement of a drag finger 63 or "pallet".

The semi-cylinder 6 is disposed within the latch body 5 so that the rotation of the key drives the positioning of the blade 63 inside the square part of the opening 512 or of the opening 522 depending on the direction of rotation of the key and , therefore, when the rotation continues, the backward movement of the latch body 5, against the force exerted by the spring 57, until the half-spindle 54 is retracted, in the passive position shown in Figure 9. This axial displacement It is carried out along the X2-X'2 axis.

It should be noted that the oblong portions of the openings 512 and 522 allow axial displacement of the latch body 5 despite the presence of the fixing screws of the half cylinder 6.

Conversely, the rotation of the key in the other direction makes it possible to return the blade in the alignment of the axis X2-X'2, then acting the spring 57 again to move the latch 5 in the active door locking position.

The lock box 1 according to the invention is also equipped with an anti-panic plate 2 whose structure and operation will now be explained in more detail.

The plate holder 7 will now be described, referring to Figure 2.

This handle comprises a central portion 70, rectangular in shape and, approximately half its length, two triangular side wings 71, 72 extending perpendicularly to said central portion 70.

The central portion 70 has several fixing holes 700, preferably one in each of its four angles, and in its middle part, two closer holes 701.

In addition, the sheet that constitutes the handle 7 has been cut in the central area of this handle according to a C-cut, and the sheet has been folded, so that it forms a rectangular recess 703 and a tongue 702 that extends in a plane parallel to wings 71 and 72.

The lower tip of the triangle of each wing 71, 72 is also perforated by a hole 710, respectively 720.

The inclined edge of the triangle of each wing 71, 72 preferably has a semicircle shaped recess bearing the reference 711, respectively 721, these recesses facilitating the passage of the assembly screws of the semi-cylinder 6 and the cabinet 3.

As can be seen in Figure 1, the pusher 8 is formed from a sheet of substantially rectangular shape much longer than wide. This sheet is folded along its two longitudinal edges in such a way that it has a central portion 80 and two lateral wings 81 and 82 of low height.

It is perforated at its front end by holes 800, preferably four, arranged in the four corners of a rectangle so that they are located in front of the holes 700 of the handle 7, when these two elements are assembled. This assembly is carried out, for example, by screws 801 and nuts not

represented in the figures.

The piece in L 9 has two wings 90 and 91 that are perpendicular to each other. The wing 90 has a rectangular shape and is perforated by two holes 900. These holes are spaced the same distance as the holes 701 of the handle 7.

The L-piece 9 is mounted on the handle 7, so that the wing 90 comes into contact with the inner face of the handle 7 and that the holes 900 are aligned with the holes 701. Thus, both parts are assembled by means of Rivets that pass through these two holes. Once assembled, the wing 91 therefore extends perpendicularly to the plane of the central portion 70 of the handle 7.

The wing 91 has a substantially rectangular area 910, adjacent to the wing 90, which extends into an area 911 in the form of an isosceles triangle of which one of the two equal sides is located in the extension of the rectangular area 910. The triangular area 911 It is extended by a hook 912.

The flank of the base of the isosceles triangle 911 constitutes an inclined ramp 913.

The flank 914 of the hook 912 which is located in the extension of the inclined ramp 913 constitutes a stop stop.

The inclined ramp 913 and the flanking edge 914 are spaced at an angle a of a value between 125 and 140 °, preferably close to 135 °.

The plate 2 is mounted on the cabinet 3 so that it can pivot angularly around an axis materialized only in Figures 8 to 10 by the dashed line YY 'and passing through the holes 710, 313, 323 and 720. That Pivot mounting can be secured for example by screws and nuts.

In addition, a spring 73 called "plate spring" (for example a helical spring) is positioned between the handle 7 and the cabinet 3 so that one of its ends is fixed to the tongue 702 and the other is received from behind the recess 300, the latter also authorizing the passage of the piece in L 9. That spring 73 permanently tends to separate the handle, and therefore the pusher 8, from the cabinet 3.

In addition, when the plate 2 and the lock box 1 are assembled and at rest, the shaft 56 is housed at the intersection between the stop 914 and the inclined ramp 913 (see Figure 8). The slot 58 allows the passage of the wing 91.

The pivot axis Y-Y1 is perpendicular to the axes X-X1, X1-X1 and X2-X'2.

When the operator cannot use the key (for example because he is injured), he rests with the body on the pusher 8, against the force exerted by the spring 73, which causes the pivoting of the piece in L 9. The inclined ramp 913 then rests on the stud 56 and moves it backwards, against the force exerted by the spring 57, until the latch body 5 is brought in its passive position represented in figure 10. In this position, the half-spindle 54 is in the retracted position and the door can be opened. The reverse movement is performed as soon as the operator releases the pressure on the plate 2 and the latch body returns to the active position represented in Figure 8.

The device according to the invention allows a more commonly extended and easily replaceable European semi-cylinder to be used in case of loss of the key. Furthermore, since this semi-cylinder is symmetrical with respect to the box 1, the device according to the invention can be mounted indifferently on a door that opens to the right or to the left. This allows to optimize production and reduce costs since a single model is manufactured.

Finally, the centered position of the inclined ramp 913 and of the stud 56 with respect to the latch body 5 guarantees a homogeneous distribution of the forces.
