Abstract
Description
L'invention est relative à un pêne demi-tour réversible de serrure à mortaiser ou en applique.The invention relates to a reversible latch bolt lock in mortise or apply.
Dans les serrures à mortaiser ou en applique, le pêne demi-tour est agencé de manière à être retourné de 180° autour de son axe de déplacement pour pouvoir coopérer normalement avec une gâche, que la porte s'ouvre à droite ou à gauche.In mortise locks or wall, the latch is arranged to be turned 180 ° around its axis of movement to be able to cooperate normally with a strike, that the door opens right or left.
Dans les serrures actuelles, le retournement du pêne demi-tour nécessite de démonter au moins la couverture du coffre de la serrure avec le risque de permettre à certaines pièces de se déplacer sous l'action de ressorts divers, avec comme conséquence, d'augmenter la durée du remontage pour repositionner les pièces baladeuses entre coffre et couverture.In current locks, turning the latch bolt requires removing at least the cover of the lock box with the may allow certain parts to move under the action of springs various, with the consequence of increasing the duration of reassembly for reposition parts wandering between safe and coverage.
Le document FR 1 376 716 décrit une serrure dans laquelle le coffre et le couvercle de la serrure comportent, chacun et près de la têtière, une découpe en T couché composée d'une partie permettant la rotation du pêne et une partie formée par découpage et rabattement de pattes saillant dans le coffre et servant à l'appui du ressort chassant le pêne à l'extérieur. Pour amener le pêne en position de retournement, c'est-à-dire en coïncidence avec les découpes précitées, il faut dévisser et retirer une vis transversale formant butée de limitation de la course de rentrée du pêne.Document FR 1 376 716 describes a lock in which the box and the lock cover each comprise next to the face-plate, a coated T cut made up of a part allowing the rotation of the bolt and a portion formed by cutting and folding tabs projecting in the trunk and used to support the spring driving the bolt outside. To bring the bolt into the turning position, that is to say in coincidence with the aforementioned cutouts, unscrew and remove a transverse screw forming stop for limiting the bolt re-entry stroke.
Dans le document NL 30270, le pêne est en deux parties, et est donc composé d'un corps monté coulissant dans le coffre, et réagissant au fouillot et à un ressort de rappel, et d'une tête avec une tige cylindrique qui, équipée d'une languette élastique, est engagée dans un alésage du corps et est calée dans celui-ci par encliquetage d'un cran de la languette sur le bord d'une rainure ménagée de chaque côté du corps. Dans ce montage, c'est le cran de la languette élastique qui assure le calage en translation et le calage en rotation de la tête dans le corps du pêne. Le cran étant de petites dimensions et ne pouvant pas être surdimensionné, il en résulte qu'il est fragile et qu'une telle serrure peut très facilement être fracturée.In document NL 30270, the bolt is in two parts, and is therefore composed of a body mounted sliding in the trunk, and reacting to follower and a return spring, and a head with a cylindrical rod which, equipped with an elastic tongue, is engaged in a bore of the body and is wedged into it by snapping a notch of the tongue on the edge a groove on each side of the body. In this montage, it is the notch of the resilient tongue which provides the timing and translational stalling rotating the head in the body of the bolt. The notch being small dimensions and cannot be oversized, it results in it being fragile and that such a lock can easily be broken.
La présente invention a pour objet de remédier à ces inconvénients en fournissant un pêne demi-tour dont la réversibilité ne nécessite aucun démontage de la serrure, en réduisant ainsi le temps nécessaire à cette opération, en supprimant le risque de perte de pièce et cela sans affecter l'invulnérabilité de la serrure. The object of the present invention is to remedy these drawbacks by providing a latch bolt whose reversibility requires no disassembly of the lock, thereby reducing the time required for this operation, eliminating the risk of losing a part without affecting the invulnerability of the lock.
Elle concerne plus particulièrement les serrures comprenant un coffre en forme de boíte ouverte, lié ou non à une plaque têtière, et dont l'ouverture est fermée par un couvercle, un fouillot monté libre en rotation autour d'un axe transversal dans des paliers respectifs du coffre et de la couverture, et un pêne demi-tour à rappel par ressort monté coulissant dans le coffre, entre une position en saillie du coffre, une position d'effacement dans le coffre, et une position de retournement dans laquelle il peut être pivoté par rotation dans des découpes en T ménagées dans le coffre et le couvercle, la tête de ce pêne présentant, en section transversale, une forme générale quadrangulaire circulant dans un guidage de même forme découpée dans la plaque têtière ou dans le coffre, et étant solidaire a) d'un corps et d'une queue coulissants dans le coffre, b) d'une collerette coopérant avec le fouillot et avec un ressort de rappel, et c) d'un moyen de butée limitant la course de rentrée du pêne dans le coffre.It relates more particularly to locks comprising a chest in the shape of an open box, whether or not linked to a faceplate, and of which the opening is closed by a cover, a follower mounted free to rotate around a transverse axis in respective bearings of the trunk and the cover, and a spring return latch bolt slidably mounted in the trunk between a position protruding from the trunk, an erasure position in the trunk, and a turning position in which it can be pivoted by rotation in T-shaped cutouts in the trunk and lid, the head of this bolt having, in cross section, a general shape quadrangular circulating in a guide of the same shape cut in the faceplate or in the trunk, and being integral a) with a body and a tail sliding in the trunk, b) a flange cooperating with the follower and with a return spring, and c) a stop means limiting the return stroke of the bolts in the trunk.
Dans la serrure selon l'invention, le corps du pêne est monolithique avec sa tête, sa queue et une languette, élastiquement déformable, disposée longitudinalement contre ce corps et dont l'extrémité libre, opposée à la tête du pêne, constitue moyen de butée limitant la course de rentrée du pêne dans le coffre, en coopérant avec le fond de la découpe correspondante dans laquelle elle est disposée, cette languette étant déformable élastiquement de façon que, pour l'opération de retournement, son extrémité libre puisse être plaquée contre le corps pour passer sous la paroi contre laquelle elle vient normalement en butée, pour, d'une part, augmenter la course de rentrée du pêne, et d'autre part, permettre à la tête de ce pêne d'échapper du guidage en forme et de venir en totalité dans la zone des découpes, du coffre et du couvercle, où cette tête peut être retournée de 180° avec le corps.In the lock according to the invention, the body of the bolt is monolithic with its head, its tail and a tongue, elastically deformable, disposed longitudinally against this body and whose free end, opposite the head of the bolt constitutes stop means limiting the collapse stroke of the bolt in the chest, cooperating with the bottom of the corresponding cut in which it is arranged, this tongue being elastically deformable so that, for the turning operation, its free end can be pressed against the body to pass under the wall against which it is normally into abutment, on the one hand, increase the collapse stroke bolt and on the other hand, allow the head of this bolt to escape from the shaped guide and come completely into the cutout, trunk and lid area, where this head can be turned through 180 ° with the body.
Avec cet agencement, lorsque la serrure n'est pas encore mise en place sur la porte, le retournement du pêne demi-tour s'effectue très aisément en appuyant transversalement sur la languette pour amener son extrémité libre au-dessous du niveau de la paroi contre laquelle elle vient en butée, puis en appuyant sur la tête du pêne pour provoquer son recul dans le coffre jusqu'à ce que sa tête échappe de la découpe de guidage ménagée dans la têtière ou la paroi du coffre.With this arrangement, when the lock is not yet in use Place on the door, flipping the latch is done very easily pressing transversely on the tongue to bring its free end below the level of the wall against which it abuts, then in pressing the head of the bolt to cause its decline in the trunk until that his head escapes from the guide cutout made in the headrest or the trunk wall.
A partir de là, et tout en maintenant le pêne poussé, il suffit de le faire pivoter de 180° dans les découpes ménagées à cet effet, dans le coffre et dans le couvercle du coffre. Dès que cette rotation est terminée et que la tête revient en coïncidence avec sa forme de guidage ménagée dans la têtière ou la paroi du coffre, le relâchement de ce pêne permet à ses moyens de rappel de le ramener automatiquement dans sa position de fonctionnement, en permettant à sa languette de reprendre élastiquement sa position pour constituer une butée limitant la rentrée du pêne dans le coffre.From there, and while holding the latch pushed, simply the rotate through 180 ° into the cutouts provided for this purpose in the boot and in the trunk lid. As soon as this rotation is complete and the head back into coincidence with the guide shape formed in the headrest or the trunk wall, the release of this bolt allows its return means to return automatically in its operating position, in allowing its tongue to resiliently return to its position for constitute a stop limiting the retraction of the bolt in the trunk.
Il ressort de ce qui précède que cette opération s'effectue très rapidement, sans qu'il soit nécessaire de démonter l'un quelconque des composants de la serrure.It follows from the above that this is done very quickly, without the need to disassemble any of the components of the lock.
Dans une forme d'exécution de l'invention, un épaulement, formé entre le corps et la queue du pêne, est en retrait de l'extrémité libre de la languette pour constituer, en coopérant avec le fond des découpes, un second moyen de butée limitant la course de rentrée du pêne dans sa phase de retournement.In one embodiment of the invention, a shoulder, formed between the body and tail of the bolt, is set back from the free end of the tongue to form, by cooperating with the bottom of the cutouts, a second stop means limiting the retraction stroke of the bolt during its turnaround.
Avantageusement, la queue du pêne comporte un alésage axial débouchant qui, dans la phase de retournement du pêne et lorsque que ce dernier est en position rentrée, coopère avec un doigt du boítier pour guider la rotation de retournement de ce pêne.Advantageously, the tail of the bolt has an axial bore opening which, in the phase of turning the bolt and when it last is in the retracted position, cooperates with a finger of the housing to guide the turning rotation of this bolt.
Ces moyens de guidage, qui entrent en action dès que le pêne affleure la têtière, garantissent d'une part, le positionnement longitudinal du pêne et, d'autre part, son guidage en rotation dans la phase de retournement.These guide means, which come into action as soon as the bolt is flush with the headrest, guarantee on the one hand, the longitudinal positioning of the bolt and, on the other hand, its guiding in rotation in the turning phase.
D'autres caractéristiques et avantages ressortiront de la description
qui suit en référence au dessin schématique annexé représentant, à titre
d'exemple, une forme d'exécution du pêne demi-tour selon l'invention dans le
cas de son application à une serrure à mortaiser.
Cette serrure est composée d'un coffre 2, en tôle emboutie et en
forme de boíte ouverte, d'un couvercle 3 obturant l'ouverture de la boíte
précitée, d'un pêne 4 et d'une têtière 5.This lock consists of a
Comme le montre plus en détails la figure 2, le pêne 4 est
monolithique et est composé d'une tête prismatique 4a, d'un corps 4b, d'une
queue 4c. Dans la forme d'exécution représentée, le corps 4b et la queue 4c
sont de forme générale cylindrique, mais de diamètres différents, le corps étant
plus gros que la queue. La tête 4a présente, en section transversale une forme
quadrangulaire, délimitée entre deux faces planes parallèles 6 et 7, et deux
faces concaves 8 et 9. La têtière 5 est traversée par une découpe de guidage
10 dont la forme est complémentaire de celle de la tête 4a, de manière à en
assurer le guidage quelle que soit la position d'utilisation de cette tête. La figure
4 montre que l'épaisseur E1 de la tête 4a est supérieure à l'épaisseur E de
l'ensemble du boítier de serrure.As shown in more detail in Figure 2, the
Le corps 4b du pêne a une dimension transversale, et en l'occurrence un diamètre D2 dont la valeur est sensiblement égale à celle de l'épaisseur E de l'ensemble du boítier de serrure.The body 4b of the bolt has a transverse dimension, and in the occurrence of a diameter D2 whose value is substantially equal to that of the thickness E of the entire lock case.
Pour permettre les mouvements du pêne, la paroi 2a du coffre 2 et
la paroi 3a du couvercle 3, sont chacune munie d'une découpe 11a, 11b dont
la hauteur permet la rotation du pêne. Cette découpe est prolongée par une
découpe 12a, 12b de moindre hauteur pour le passage du corps du pêne. Ces
deux découpes forment une découpe en T couché.To allow the bolt movements, the wall 2a of the
Le corps 4b du pêne 4 est solidaire du pied d'une languette
longitudinale 13 dont l'extrémité libre est tournée à l'opposé de la tête 4a du
pêne. Cette languette est délimitée dans le corps 4b par une fente 14 qui est
parallèle aux deux faces planes 6 et 7 délimitant la tête 4a du pêne.The body 4b of the
Comme le montre les figures 1, 3 et 4, la languette 13 peut, circuler
dans la découpe 12a ou 12b et, par exemple, dans celle 12b à la figure 3.As shown in Figures 1, 3 and 4, the
Dans la forme d'exécution représentée, un épaulement 15 est
formé entre le corps 4b et la queue 4c du pêne. Cet épaulement est en retrait
de l'extrémité libre de la languette 13, pour constituer une butée utilisable
pendant la phase de retournement. In the embodiment shown, a
Il faut ici préciser que l'ensemble du pêne 4 tel que représenté peut
être réalisé par usinage traditionnel, mais aussi par frittage selon le procédé
MIM.It should be noted here that the
La queue 4c du pêne est solidaire d'une collerette 16 dont l'une des
faces diamétrales coopère avec le nez 17a d'un fouillot 17, monté libre en
rotation dans des paliers du coffre 2 et du couvercle 3, tandis que son autre
face diamétrale sert d'appui à un ressort 18. Ce dernier prend appui, par son
autre extrémité, sur une patte 19, formée par défoncement de la paroi 2a du
coffre 2. Cette patte 19 est contrecoudée pour former un doigt 20 qui est
sensiblement disposé dans l'axe longitudinal du pêne, et qui est destiné à
pénétrer dans un alésage axial borgne 22 débouchant de l'extrémité libre de la
queue du pêne.4c the tail of the bolt is secured to a
Enfin, comme montré plus particulièrement à la figure 3, de la paroi
2a du coffre 2 font saillies deux pattes 23 qui, disposées de part et d'autre du
corps 4b du pêne, participent à son guidage en translation longitudinale.Finally, as shown more particularly in Figure 3, the wall
2a of the
Lorsque la serrure est montée sur une porte et que la porte est
ouverte, le pêne demi-tour est dans la position montrée aux figures 1 et 3,
position dans laquelle sa tête 4a fait saillie de la têtière 5, son corps 4b est
entièrement disposé dans les découpes 11a, 11b et 12a, 12b, sa languette 13
est éloignée du fond 120a ou 120b de la découpe 12a ou 12b et sa queue 4c
est disposée entre les parois 2a et 3a du boítier.When the lock is mounted on a door and the door is
open, the latch bolt is in the position shown in Figures 1 and 3,
position in which its head 4a projects from the
Lorsque la porte est fermée, le contact de la tête 4a du pêne avec
la gâche provoque le recul de celui-ci à l'intérieur du boítier en comprimant le
ressort 18. Pour ouvrir la porte, l'actionnement du fouillot 17 dans le sens de la
flèche 21 à la figure 3 provoque, par appui de son nez 17a sur la collerette 16,
le déplacement de l'ensemble du pêne dans le sens de la flèche 31 jusqu'à une
position de butée, montrée à la figure 4, dans laquelle, d'une part, la languette
13 vient en appui sur le fond 120a ou 120b de la découpe 12a ou 12b dans
laquelle elle se meut, et d'autre part, la face en bout de la tête 4a du pêne est
en retrait par rapport à la face extérieure de la têtière 5. On notera que, dans
cette position, l'alésage 22 de la queue du pêne est déjà engagé sur le doigt 20
du coffre 2.When the door is closed, the contact of the bolt head 4a with
the strike caused the decline of the latter within the housing compressing the
Pour procéder au retournement du pêne, il suffit, après l'avoir
amené dans une position proche de celle représentée à la figure 4, d'exercer
sur l'extrémité libre de sa languette 13, un effort radial la déformant
élastiquement en permettant à cette extrémité de passer sous la paroi 3a
contre laquelle elle venait jusqu'alors en butée. Dans cette position de la
languette montrée à la figure 5, le pêne peut être poussé davantage à
l'intérieur du boítier, de manière que la face en bout de sa tête 4a échappe du
profil de guidage 10 ménagé dans la têtière 5. Quand le pêne est dans cette
position, et comme montré à la figure 6, il est très aisé de procéder à son
retournement manuel en le faisant pivoter de 180°. Ce retournement est
d'autant plus aisé que, durant cette rotation, le pêne est guidé, d'une part, près
de sa tête par les deux pattes 23, et d'autre part, à l'extrémité de sa queue 4c,
par le doigt 20 qui forme axe de rotation en coopérant avec la paroi de
l'alésage borgne 22.To turn the latch, you just have to
brought into a position close to that shown in Figure 4, to exercise
on the free end of its
La figure 5 montre que l'engagement de la queue 4c du pêne dans
le boítier est limité par butée de l'épaulement 15 de son corps 4b contre le bord
120a de la découpe 12a ménagée dans la paroi 2a du coffre, et ceci, afin d'une
part, de limiter la compression du ressort 18, et d'autre part, d'éviter le
coincement de la languette 13 sous la paroi 3a de la couverture 3.FIG. 5 shows that the engagement of the tail 4c of the bolt in
the housing is limited by abutment of the
Lorsque le pêne a effectué une rotation de 180°, et que sa tête 4a
est en coïncidence avec sa forme de guidage 10, il est relâché afin que, sous
l'action de son ressort 18, il reprenne sa position de fonctionnement. Ce
déplacement, dans le sens de la flèche 32 de figure 5, permet à l'extrémité libre
de la languette 13 d'échapper de dessous la paroi 3a et, par élasticité, de
reprendre sa position initiale et dans la découpe 12a du coffre 2.When the bolt has rotated 180 °, and its head 4a
is coincident with the shape of
