Description

Dispositif de fermeture automatique de porte, installé
au sol.
Automatic door closing device, installed
on the ground.

La présente invention concerne un dispositif de ferme ture automatique de porte, installé au sol, et comportant un bloc de fermeture monté dans un boîtier muni d'un couvercle. The present invention relates to an automatic door closing device, installed on the ground, and comprising a closing block mounted in a housing provided with a cover.

Il est connu de souder, sur le fond du boîtier d'un -dis- positif de ce genre, des équerres métalliques avec des trous taraudés. Ces trous taraudés reçoivent des vis par lesquelles le bloc de fermeture est fixé au boîtier. Mais les équerres s'oxydent facilement, surtout en raison de l'humidité qui pénètre inévitablement dans le boîtier et peut se rassembler au fond sous forme d'eau, par exemple lors du lavage du sol. It is known to weld, on the bottom of the case of a device of this kind, metal brackets with tapped holes. These tapped holes receive screws by which the closure block is fixed to the housing. However, the brackets oxidize easily, especially due to the humidity which inevitably enters the housing and can collect at the bottom in the form of water, for example when washing the floor.

L'invention a donc pour objet de réaliser la fixation du bloc de fermeture dans le boîtier de manière qu'elle soit protégée de l'oxydation. The object of the invention is therefore to secure the closure block in the housing so that it is protected from oxidation.

Dans un dispositif de fermeture automatique de porte selon l'invention, ce résultat est obtenu par le fait que des blocs de fixation sont montés sur le fond du boîtier par de-s vis vissées par le bas à travers le fond du boîtier, les blocs comportant des trous taraudés dans lesquels des vis de fixation du bloc de fermeture sont vissées par le haut. In an automatic door closing device according to the invention, this result is obtained by the fact that fixing blocks are mounted on the bottom of the case by screws screwed from below through the bottom of the case, the blocks having tapped holes into which fastening screws for the closure block are screwed from above.

La matière des blocs de fixation peut être choisie à volonté et il en est de même pour les vis qui traversent le fond du boîtier et qui sont vissées par le bas. Il est donc possible de choisir des matières qui sont économiques et insensibles à la corrosion, particulièrement à l'oxydation. The material of the fixing blocks can be chosen at will and it is the same for the screws which pass through the bottom of the housing and which are screwed from below. It is therefore possible to choose materials which are economical and insensitive to corrosion, particularly to oxidation.

Pour permettre d'utiliser un bloc de fermeture qui n'est pas destiné à être fixé sur le fond du boîtier, mais sur ses parois laterales par des croisillons, le dispositif de fermeture automatique de porte selon L'invention comporte des tôles de fixation qui sont vissées sur le bloc de fermeture par le haut,et comportent des épaulements destinés à être fixés sur des blocs de fixation. Les épaulements peuvent comporter des trous dans lesquels passent les vis de fixation par lesquelles le bloc de fermeture est fixé au boîtier. To allow the use of a closure block which is not intended to be fixed to the bottom of the housing, but to its lateral walls by cross bars, the automatic door closing device according to the invention comprises fixing plates which are screwed onto the closure block from above, and have shoulders intended to be fixed to fixing blocks. The shoulders may include holes through which the fixing screws pass through which the closure block is fixed to the housing.

Mais de préférence, la fixation est assurée par des pattes qui sont serrées contre les épaulements. But preferably, the fixing is ensured by lugs which are tight against the shoulders.

Pour éviter le fléchissement des épaulements, les tôles de fixation comportent de préférence des parties replies au-dessous des épaulements et qui s'appuient sur le bloc cle fermeture. To avoid deflection of the shoulders, the mounting plates preferably have folded portions below the shoulders and which rest on the locking key block.

I'our permettre le réglage de la hauteur du bloc de fermeture dans le boîtier sans augmenter l'encombrement, il convient de fixer au moins l'une des tôles de fixation sur le bloc de fermeture par des douilles filetées que traversent des vis de réglage de hauteur s'appuyant sur le fond du boîtier. To allow the adjustment of the height of the closure block in the housing without increasing the size, it is advisable to fix at least one of the fixing plates on the closure block by threaded sockets through which adjusting screws pass high resting on the bottom of the case.

Les pattes précitées sont réalisées de préférence de manière à être fixées sur les blocs de fixation au fond du boîtier et que le bloc de fermeture puisse être déplacé dans le boîtier par rapport à ses pattes pour l'adapter aux conditions particulières. The aforementioned tabs are preferably made so as to be fixed on the fixing blocks at the bottom of the housing and that the closure block can be moved in the housing relative to its legs to adapt it to the particular conditions.

Pour que la plaque de recouvrement du boîtier soit toujours fixée en alignement avec ce dernier, et non avec le bloc de fermeture, il est préférable que le-s trous tarau dés,destinés à recevoir les vis de fixation de la plaque de recouvrement, soient prévus sur les pattes qui sont fixées au boîtier. So that the cover plate of the housing is always fixed in alignment with the latter, and not with the closing block, it is preferable that the tarau dice holes, intended to receive the fixing screws of the cover plate, are provided on the legs which are fixed to the housing.

Pour permettre de fixer sans difficulté des pattes sur les blocs de fixation, ces pattes sont de préférence fixées sur les blocs par des vis vissées par le haut, comportant des têtes polygonales d'une dimension axiale supérieure à leur diamètre. Ces vis peuvent être mises en place en les prenant par leur tête polygonale, et en utilisant ensuite une clé. Etant donné que,lorsque les vis sont mises en place, les têtes polygonales sont encastrées, il est préférable que leur surface frontale comporte une fente de prise pour un tournevis. To allow the legs to be fixed without difficulty on the fixing blocks, these legs are preferably fixed to the blocks by screws screwed from above, comprising polygonal heads with an axial dimension greater than their diameter. These screws can be installed by taking them by their polygonal head, and then using a wrench. Since, when the screws are installed, the polygonal heads are recessed, it is preferable that their front surface has a socket for a screwdriver.

Le dispositif de fermeture automatique de porte, installée au sol, comporte un bloc de fermeture 2 fixé dans un boîtier 6 muni d'une plaque de recouvrement 4. The automatic door closing device, installed on the floor, comprises a closing block 2 fixed in a housing 6 provided with a cover plate 4.

Des blocs de fixation 12, 14, 16 sont fixés au fond 8 du boîtier 6 par des vis 10, vissées par le bas et traversant le fond 8; ces blocs comportent des trous taraudés 18 destinés à des vis 20 de fixation du bloc de fermeture 2, qui y sont vissées par le haut. Le bloc de fixation 12 comporte deux de ces trous taraudés 18, 22 qui peuvent être utilisés au choix. Fixing blocks 12, 14, 16 are fixed to the bottom 8 of the housing 6 by screws 10, screwed from below and passing through the bottom 8; these blocks have tapped holes 18 intended for screws 20 for fixing the closure block 2, which are screwed therein from above. The fixing block 12 comprises two of these tapped holes 18, 22 which can be used as desired.

Des tôles de fixation 24, 26 sont vissées par le haut sur le bloc de fermeture 2 et elles comportent des épaulements 28, 30 qui doivent être fixés sur les blocs de fixation 12, 14 et 16. Fastening plates 24, 26 are screwed from above onto the closure block 2 and they have shoulders 28, 30 which must be fixed to the fastening blocks 12, 14 and 16.

Au-dessous des épaulements 28, 30, les tôles de fixation 24, 26 comportent des parties repliées 32, 34 qui s' appuient contre le bloc de fermeture 2. Below the shoulders 28, 30, the fixing plates 24, 26 have folded parts 32, 34 which bear against the closure block 2.

La te le de fixation 26 est fixée sur le bloc de fer meture 2 par des douilles filetées 36 dans lesquelles pas sent des vis 30 de réglage de hauteur s'appuyant sur le fond 8 du boîtier 6. The mounting bracket 26 is fixed to the block of iron meture 2 by threaded bushings 36 in which not feel height-adjusting screws 30 resting on the bottom 8 of the housing 6.

Le bloc de fermeture 2 est fixé sur les blocs de fixation 12, 14, 16 par des pattes 4o, 42 par rapport auxquelles les épaulements 28, 30, et par conséquent le bloc de fermeture 2, peuvent être déplacés dans le boîtier 6. The closing block 2 is fixed on the fixing blocks 12, 14, 16 by lugs 4o, 42 with respect to which the shoulders 28, 30, and consequently the closing block 2, can be moved in the housing 6.

Les pattes 40, 42 portent des pièces taraudées 44 destinées à recevoir des vis de fixation 46 de la plaque de recouvrement 4.  The legs 40, 42 carry threaded parts 44 intended to receive fixing screws 46 of the cover plate 4.

Les pattes 4Q, 42 sont fixées sur les blocs de fixation 12, 14 et 16 par des vis vissées par le haut et qui comportent des têtes polygonales 48 dont la longueur est supérieure à leur diamètre. Leurs faces avant comportent des fentes 50 destinées à recevoir un tournevis. The legs 4Q, 42 are fixed to the fixing blocks 12, 14 and 16 by screws screwed from above and which include polygonal heads 48 whose length is greater than their diameter. Their front faces have slots 50 intended to receive a screwdriver.

Le mode de réalisation de la Figure 4 diffère de celui de la pagure I par le fait que le bloc de fixation 12 se prolonge sur toute la largeur du boîtier 6 et qu'il est fixé par des extrémités sur le fond 8 par des rivets qui traversent le fond. Ces rivets 59 sont formés aux extrémités de petits tubes 54 qui traversent le bloc de fixation 12 ct dont la partie supérieure comporte des trous taraudés dans lesqucls doivent être vissées les vis 46. Des pièces taraudées 44 de la figure 1 ne sont donc plus nécessaires. The embodiment of Figure 4 differs from that of page I by the fact that the fixing block 12 extends over the entire width of the housing 6 and that it is fixed by ends to the bottom 8 by rivets which cross the bottom. These rivets 59 are formed at the ends of small tubes 54 which pass through the fixing block 12 ct, the upper part of which has tapped holes in which the screws 46 must be screwed. Tapped parts 44 of FIG. 1 are therefore no longer necessary.

Comme il va de soi, et comme il résulte d'ailleurs déjà de ce qui précède, l'invention ne se limite nullement ceux de ses modes d'application et de réalisation qui ont été plus particulièrement envisagés ; elle en embrasse, au contraire, toutes les variantes.  As is obvious, and as already follows from the above, the invention is in no way limited to those of its modes of application and embodiments which have been more particularly envisaged; on the contrary, it embraces all its variants.
