EP0263737B1 - Keyless combination lock with coded dials and bolt dogging means - Google Patents

Description

The present invention relates to a keyless device for closing and opening a pivoting, sliding or tilting door according to the preamble of the claim.

• - pour sortir du local, il est nécessaire d'effectuer un code intérieur, le dispositif ne présente pas de système rapide de deverrouillage de l'intérieur ou, s'il existe, il n'est pas précisé.
• - Une clé peut être nécessaire pour ouvrir la porte, ce qui est contradictoire d'un système à code où seul celui-ci doit permettre l'accès a un local.
• - Lorsqu'on arrive de l'extérieur face au dispositif verrouillé, la pièce 34 qui dépasse du bouton 20 semble fragile (le schéma étant agrandi) et risque fortmenet d'être soumise au vandalisme.
• - Le changement de code très aisé à effectuer peut devenir un inconvénient; dans l'état actuel du schéma fig. 2, n'importe quelle personne se trouvant à l'intérieur peut tourner un des boutons codés (par exemple, un enfant peut tourner les boutons codés de l'intérieur et ainsi brouiller le code extérieur) modifiant donc la position du créneau correspondant ce qui modifie le code à effectuer de l'extérieur pour entrer.
• - Le dernier point à soulever concerne le décodage de ce dispositif. Comme l'indique le schéma 2 et la revendication 1, chaque cylindre 26 ou 56, 58, 60 possèdent un seul créneau. Toute personne peut ouvrir le dispositif de la manière qui suit:

Such a device, known from document US-A 4 220 023 has the following drawbacks:

• - to leave the room, it is necessary to carry out an interior code, the device does not have a quick unlocking system from the inside or, if it exists, it is not specified.
• - A key may be necessary to open the door, which is contradictory to a code system where only this must allow access to a room.
• - When you arrive from the outside facing the locked device, the part 34 which protrudes from the button 20 seems fragile (the diagram being enlarged) and is likely to be subject to vandalism.
• - The very easy code change can become a drawback; in the current state of the diagram fig. 2, any person inside can turn one of the coded buttons (for example, a child can turn the coded buttons from the inside and thus scramble the outside code) thus modifying the position of the corresponding slot which modifies the code to be carried out from outside to enter.
• - The last point to raise concerns the decoding of this device. As shown in Figure 2 and claim 1, each cylinder 26 or 56, 58, 60 has a single slot. Anyone can open the device in the following ways:

• - Il n'est pas mentionné ni dans les textes ni dans le schémas comment la personne agit sur le système pour déverrouiller et sortir de l'intérieur.

By pushing the button 34 this pushes the bar 37 in the direction of the arrow 38 until contacting the protrusions 44, 46 and 48 with the corresponding cylinders 56, 58 and 60. At this time by turning the buttons 18 , 20 and 22 we detect the clearance between each cylinder 26 and each protuberance 42. While still pressing the button 34, we can then go to the next number for a button (18 for example), if the clearance seems identical, this n is not the correct code number, when the button is positioned on its correct code we will have in addition to the usual game, the game which corresponds to the width of the slot (for example slot 64 and protuberance (44) and so on for each button.

• - It is not mentioned in the texts or in the diagrams how the person acts on the system to unlock and exit from the inside.

The present invention which is the subject of the patent application makes it possible to eliminate these drawbacks by providing a device of the type mentioned, characterized in that on the outside of the door, this device is composed of the following elements; the coding buttons have a through hole and blind holes, these holes being disposed at equal distance from the axis of rotation of the coding button considered, the angular position of the through hole relative to the mark on the button (area A) determining the code of the latter, a female puller movable axially and perpendicular to the plane of the door is placed on the outer face of the door and located in the center of the coded buttons, so that the axes of the coding buttons are located on a circle having for center the axis of the zipper, this zipper having studs, each of which can penetrate either into the blind hole or into the through hole of each coding buttons, according to the angular positions of the latter, and in that on the other side of the door (interior) the device comprises either an interior coded system comprising a male interior pull tab, the end of which fits in when necessary ideally of the female pull tab, the two coded interior and exterior systems being identical, that is to say a finger movable axially and perpendicular to the plane of the door by an internal screw nut system, this finger normally being housed in the recess of the female pull tab this in crossing the bolt and opposing the movement of the bolt as long as this finger or the interior zipper is engaged with the exterior zipper, the handle or the control button of the bolt being released when the end of the interior zipper or the finger n 'is more engaged with the recess of the outer pull, which occurs when the studs penetrate into the through holes of the coding buttons as a result of the correct positioning of the coding buttons.

• La première sous forme d'un boitier renfermant le mécanisme et pouvant s'appliquer sur la surface de la porte à l'intérieur du local, environ à mi-hauteur, à gauche comme à droite.

This device, very simple to use, will be very robust and very difficult to decode. It can be conceived in several ways:

• The first in the form of a box containing the mechanism and which can be applied to the surface of the door inside the room, about halfway up, on the left and on the right.

The second can be accommodated in the thickness of the door, only the length of the turning of the coded buttons 1 and the pull tab 2 or 6 differs.

• L'un sans mécanisme codé mais, avec verrou fig. 4, 5 et 6 (verrou: pièces 10, 12, 13, 14).

For these two cases, the opening and closing (with blocking of the door will be carried out from the outside as from the inside but, characterized on the inside by two different operating principles:

• One without coded mechanism but, with lock fig. 4, 5 and 6 (lock: parts 10, 12, 13, 14).

The other with coded mechanism fig. 7 and 8.

• - Une plaque avant gravée 19, elle est appliquée extérieurement contre la porte et fixée à l'aide de goujons soudés à l'arrière de cette plaque; elle comporte des gravures (autour de chaque roulette) à la manière d'une horloge, pour positionner chaque roulette 1, fig. 1, zone A
• - Une plaque 20 située entre 19 et la porte, cette plaque est traitée antipercement, fig. 4
• - Un bouton central ou tirette 2, fig. 1, 2. Cette pièce permet le blocage (ou le déblocage) de la plaque mobile 10 (ou pène) fig. 1, 2, 4, 5, 6
• - des boutons codés 1 situés à la périphérie de la tirette 2, fig. 1, 2, 3, 4, 5, 6, 7

In this case, the interior code and the exterior code can be identical, they can be changed by the user. The particularly advantageous developments of the device according to the invention are the subject of the dependent claims. One form of the invention is described by way of nonlimiting example with reference to the appended drawings, in which are distinguished:

• - An engraved front plate 19, it is applied externally against the door and fixed using studs welded to the rear of this plate; it includes engravings (around each caster) in the manner of a clock, to position each caster 1, fig. 1, zone A
• - A plate 20 located between 19 and the door, this plate is treated with anti-drilling, fig. 4
• - A central button or pull tab 2, fig. 1, 2. This part allows the blocking (or unblocking) of the movable plate 10 (or bolt) fig. 1, 2, 4, 5, 6
• - coded buttons 1 located at the periphery of the pull tab 2, fig. 1, 2, 3, 4, 5, 6, 7

• - une poignée 15, fig. 1, 2, 3, actionnant le pène (10 fig. 4, 5, 6 ou pène 7 et 8, Fig. 7, 8) latèralement (à gauche ou à droite) par l'intermédiaire d'une biellette 16, fig. 3 mais, le pène pouvant être déplacé par un autre système du genre crémaillère ou autre. Le pène peut aussi actionner divers points d'ancrage en haut, en bas et latéralement. Fig. 2. Cette figure 2 représente le dispositif (ou la serrure sans clef) appliqué sur la porte coté intérieur, laissant apparaitre le pène et le départ des tringles en haut et en bas.

Their number may vary, in this case there are 5. In the case of 4 or 6 buttons, some usi swimming would be facilitated, the number of combinations varying enormously.

• - a handle 15, fig. 1, 2, 3, actuating the bolt (10 fig. 4, 5, 6 or bolt 7 and 8, Fig. 7, 8) laterally (left or right) by means of a link 16, fig. 3 but, the bolt can be moved by another system of the rack or other type. The bolt can also activate various anchor points at the top, bottom and laterally. Fig. 2. This figure 2 represents the device (or the keyless lock) applied to the interior side door, revealing the bolt and the start of the rods at the top and bottom.

Figure 3 (interior view of the device) gives an overview of the position of the coded buttons; with a hole opening by button corresponding to the five studs 3 of the pull tab (since there are five reoulettes 1). The other torus of each roulette, being non-opening, serving as lures. There is also a link 16.

Figure 4 is a section showing the locking system (and unlocking) of the bolt 10, without coded mechanism inside the room.

• ^* Afficher le code personnel et secret à l'aide des boutons 1 (ainsi chaque trou de chaque roulette se trouve en face d'un des goujons de la tirette 2)
• ^* Tirer vers soi la tirette 2 (voir fig. 5)
• ^* Tourner la poignée 15 jusqu'à butée
• ^* Pousser la porte et entrer.

The operation is simple. In this position, the bolt 10 is locked from the inside and from the outside. To open from the outside and enter, proceed as follows:

• ^* Display the personal and secret code using the buttons 1 (so each hole of each caster is in front of one of the studs of the zipper 2)
• ^* Pull the pull tab 2 towards you (see fig. 5)
• ^* Turn the handle 15 until it stops
• ^* Push the door and enter.

• - Tirer vers soi l'ensemble 12 fig. 6
• - Faire coulisser cet ensemble 12 et le pène 10 qui sont solidaires, dans le sens de la gâche, jusqu'à butée
• - Repousser la pièce 12 pour que son goujon se loge dans la tirette femelle 2
• - Pour maintenir cette pièce 12 en position, revisser l'écrou moleté 13 fig. 4.

Then push in the pull tab 2 and scramble the code before closing the door. To close from the inside, it suffices to unscrew the knurled nut 13 on the screw 14 which is itself locked on the bolt 10.

• - Pull the assembly 12 fig. 6
• - Slide this assembly 12 and the bolt 10 which are integral, in the direction of the strike, until stop
• - Push back the part 12 so that its stud is housed in the female pull tab 2
• - To keep this part 12 in position, screw the knurled nut 13 fig. 4.

• - Desserrer l'écrou moleté 1, 3
• - Tirer vers soi l'ensemble 12 pour dégager son goujon de la tirette femelle 2
• - coulisser l'ensemble 10, 12, 13, 14, fig. 4 jusqu'à une butée de manière à sortir le pène de la gâche du chambranle.
• - Repousser l'ensemble 12 de manière à loger son goujon dans une cavité de la plaque intermédiaire 11, fig. 5, zone B
• - ouvrir la porte et, de l'extérieur, pour fermer la porte; faire le code à l'aide des boutons codés
• - tirer vers soi la tirette femelle 2
• - tourner la poignée 15 pour faire glisser la plaque coulissante ou pène 10 dans la gache du chambranle
• - repousser la tirette 2 et brouiller le code en tournant les boutons 1 dans n'importe quel sens.

To leave the room, the operation is reversed, namely:

• - Loosen the knurled nut 1, 3
• - Pull the assembly 12 towards you to release its stud from the female pull tab 2
• - slide the assembly 10, 12, 13, 14, fig. 4 to a stop so as to take the bolt out of the door frame keeper.
• - Push back the assembly 12 so as to accommodate its stud in a cavity in the intermediate plate 11, fig. 5, zone B
• - open the door and, from the outside, to close the door; do the code using the coded buttons
• - pull the female pull tab 2 towards you
• - turn the handle 15 to slide the sliding plate or bolt 10 into the door frame keeper
• - push the pull tab 2 and scramble the code by turning the buttons 1 in any direction.

Figures 7 and 8 are sections revealing the locking mechanism (and unlocking) of the bolt with the coded device inside and outside the room. To open from the outside as from

• - faire le code à l'aide des boutons 1
• - tirer vers soi la tirette 6 (2 pour l'int.) pour la dégager de la tirette en vis à vis 2 (6 pour l'int.)
• - tourner la poignée pour faire coulisser le pène jusqu'à ce qu'il soit dégagé de la gache (ou jusqu'en butée); la porte s'ouvre alors librement.
• - enfoncer la tirette et, brouiller le code.

inside:

• - enter the code using buttons 1
• - pull the pull tab 6 (2 for the inside) towards you to disengage it from the facing pull tab 2 (6 for the inside)
• - turn the handle to slide the bolt until it is released from the strike (or until it stops); the door then opens freely.
• - push the pull tab and scramble the code.

• - tirer à soi la tirette 2 (ou 6 pour l'ext.) pour la dégager de la tirette en vis à vis 6 (2 pour l'ext.)
• - tourner la poignée pour faire coulisser le pène de manière à ce qu'il s'engage dans la gache jusqu'à une butée.
• - repousser la tirette 2 (ou 6) pour qu'elle s'engage dans le goujon de la tirette 2 (ou 6)
• - brouiller le code en tournant les boutons 1.

From inside (or outside if you went out) close the door; do the inside (or outside) code

• - pull the pull tab 2 (or 6 for the ext.) to release it from the pull tab opposite 6 (2 for the ext.)
• - turn the handle to slide the bolt so that it engages in the keeper until it stops.
• - push the pull tab 2 (or 6) so that it engages in the stud of the pull tab 2 (or 6)
• - scramble the code by turning the buttons 1.
