Abstract

The invention relates to a locking device comprising two combs 10, placed opposite each other, which each slide inside one of the longitudinal members 3 of the frame 1 and which engage in the grooves made in the leaves of the covers 2. The movement of these combs is controlled by means whose power source is external and independent.

Description

Les chambres sous chaussées, particulièrement celles exploitées par les téiécommunications, reçoivent des appareillages vulnérables et coûteux. I1 est donc nécessaire, voir indispensable des les recouvrir par des couvercles inviolables. Chambers under pavement, particularly those operated by telecommunications, receive vulnerable and expensive equipment. It is therefore necessary, even essential, to cover them with tamper-evident covers.

Les trappes utilisées se composent d'un cadre, scellé sous chaussee, et de vantaux amovibles de préférence triangulés pour assurer leur stabilité au passage des véhicules.The hatches used consist of a frame, sealed under the carriageway, and removable leaves, preferably triangulated to ensure their stability when passing vehicles.

La présente invention décrit un système de verrouillage pour ces trappes à multivantaux qui interdit l'ouverture partielle ou totale de couvercles de l'extérieur. The present invention describes a locking system for these multi-level hatches which prohibits the partial or total opening of covers from the outside.

La description ci-après porte sur une trappe, à 3 vantaux, plus particulièrement utilisée par les télécommunications. La présente invention n'est pas limitative à ce matériel, mais adaptable à toute disposition en ligne quelqu'en soit le nombre et le type des couvercles. The description below relates to a hatch, with 3 leaves, more particularly used by telecommunications. The present invention is not limited to this material, but can be adapted to any online arrangement, whatever the number and type of covers.

La trappe se compose d'un cadre (I) et de 3 couvercles (2) composés chacun de 2 triangles reliés entre-eux mais non bloqués ou disposés isolément. Le cadre (I) comprend 2 longerons (3) en vis à vis reliés entre eux par 2 traverses d'extrémités (4 et 5). Les longerons sont à 2 niveaux, le niveau supérieur (6) sert de batée aw tampons et le niveau inférieur (7) de glissière aux verrous. A l'intérieur du compartiment (7) sont disposées, sous les appuis des tampons, des nervures verticales (8) non reliées a la table supérieure (9) et qui forment avec le dessous de la table (9) une glissière à l'intérieur de laquelle coulisse longitudinalement le peigne (10). The hatch consists of a frame (I) and 3 covers (2) each made up of 2 triangles linked together but not blocked or arranged in isolation. The frame (I) includes 2 side members (3) facing each other connected by 2 end crossmembers (4 and 5). The longitudinal members are on 2 levels, the upper level (6) serves as a pad awning and the lower level (7) as a slide for the latches. Inside the compartment (7) are arranged, under the supports of the buffers, vertical ribs (8) not connected to the upper table (9) and which form with the underside of the table (9) a slide at the inside of which the comb (10) slides longitudinally.

Le peigne (10) qui porte des dents (11) en surépaisseur
comble l'espace laissé libre entre le sommet des nervures (8) et la table (9) à l'endroit précis de l'application des couvercles (2) de sorte que les charges imprimées aux couvercles
soient réparties sur la semelle (12) du cadre et par après à
la maçonnerie. Les dents (11) du peigne sont saillantes''à
l'intérieur du cadre et sont disposées à proximité des joues de sécurité (13) des couvercles. Un peigne est disposé dans
chacun des longerons (3) du cadre, il peut coulisser longitudinalement de sorte que les dents (11), disposées à proximité des
joues de sécurité (13), s'engageant dans des rainures (143 pra
tiquées dans ces dernières.Chacun des peignes (10) est guidé
à l'une de ces extrémités, par une glissière (15) solidaire du
longeron (3), l'autre extrémité étant reliéeà la traverse (16)
qui les actionne ensemble, verrouillant ainsi chacun des éléments
des couvercles. La traverse (16) est elle-même actionnée par un vérin pneumatique à double effet (17) > par exemple, fixé sous
le tablier (18) en extrémité du cadre et uniquement accessible de par l'intérieur de la fosse. Le tablier (17) porte également
accessible de l'extérieur un trappillon (19) à charnière, bloquée par une vis (20) à tête spéciale en forme de triangle par exem ple qui occulte les alimentations du vérin dont la source est indépendante et extérieure.
The comb (10) which carries teeth (11) in excess thickness
fills the space left free between the top of the ribs (8) and the table (9) at the precise location of the application of the covers (2) so that the loads imprinted on the covers
are distributed over the sole (12) of the frame and thereafter
masonry. The teeth (11) of the comb are protruding ''
inside the frame and are arranged near the safety cheeks (13) of the covers. A comb is placed in
each of the frame members (3), it can slide longitudinally so that the teeth (11), arranged near the
safety cheeks (13), engaging in grooves (143 pra
each of the combs (10) is guided
at one of these ends, by a slide (15) integral with the
side member (3), the other end being connected to the crossmember (16)
which operates them together, thus locking each of the elements
covers. The crosspiece (16) is itself actuated by a double-acting pneumatic cylinder (17)> for example, fixed under
the apron (18) at the end of the frame and only accessible from the inside of the pit. The apron (17) also carries
accessible from the outside a hinged trap door (19), blocked by a screw (20) with a special head in the shape of a triangle, for example, which obscures the power supplies to the jack, the source of which is independent and external.

La manoeuvre de la trappe s'opère de la façon-suivante :
1 - ouverture du trappillon (18) pour permettre le branchement
de source d'énergie extérieur
2 - Ouverture des verrous par action du vérin (17) sur la traverse
(16) et sur les peignes (10).
The operation of the hatch operates as follows:
1 - opening the hatch (18) to allow connection
external energy source
2 - Opening of the latches by action of the jack (17) on the cross-member
(16) and on the combs (10).

Le déplacement des verrous (10) dégage les dents (11) des rainures (14) autorisant ainsi le soulèvement des couvercles et donc leur ouverture. The movement of the latches (10) releases the teeth (11) from the grooves (14) thus allowing the lids to be lifted and therefore opened.

La manoeuvre de fermeture s'opère de façon inverse,
c'est-à-dire : remise en place des couvercles, alimentation du vérin par l'orifice de fermeture, dégagement de la source d'éner-
gie et fermeture du trappillon (18). Les dents (11) des peignes
ont repris leur place à l'intérieur des rainures (14) et interdisent alors le soulèvement des couvercles.
The closing operation operates in reverse,
that is to say: replacing the covers, feeding the actuator through the closing orifice, releasing the power source
gie and closing of the trap door (18). The teeth (11) of the combs
have resumed their place inside the grooves (14) and then prohibit the lifting of the covers.

La disposition des dents (11) sur les peignes (10) est telle que les couvercles n1 ont pas de position préférentielle. The arrangement of the teeth (11) on the combs (10) is such that the covers do not have a preferred position.

Une variante de réalisation suivant la figure V consiste à remplacer l'un des peignes (10) par des crochets (21) s'engageant sous la table (9) du longeron. La traverse (16) est alors remplacée par un balancier (22) articulé sous le tablier (18) et commandant le déplacement du seul peigne restant. An alternative embodiment according to FIG. V consists in replacing one of the combs (10) with hooks (21) engaging under the table (9) of the spar. The crosspiece (16) is then replaced by a balance (22) articulated under the apron (18) and controlling the movement of the only remaining comb.

Une telle disposition oblige à une position préférentielle des couvercles.  Such an arrangement requires a preferential position of the covers.
