Definitions
- the subject of the present invention is a locking device for an access hatch underground galleries and civil engineering works, especially those of telephone networks, that said hatch is made up of one or more leaves.
- the bolted hatches have the downside that the bolts are likely to rust and seize, making it difficult for them opening and closing.
- the device for locking a hatch access to galleries and underground civil engineering works consisting of at least one leaf, is characterized in that on the one hand, a so-called service leaf, is equipped with a lock which can be operated from the outside by means of a key, and that on the other hand said service leaf and the one or more other leaves, called slave leaves, include means who, in association with the other slave leaves or with the frame of the structure, allow the connection said slave leaves between themselves or in the frame, so that the removal of said slave leaves cannot be performed, on the one hand only after unlocking and removal of said service leaf, and on the other hand only after sliding relative of at least one slave leaf relative to the frame dormant, so that said means separate anchor points provided on the frame.
- the sleeping frame has in its edges longitudinal engravings or horizontal stops intended to receive locking fingers arranged laterally on each of the leaves, welded to their face lower.
- a leaf is installed by sliding horizontal of said leaf on the bottom of the frame rebate until its locking fingers borrow inclines leading to the engravings, or else they fit under the horizontal stops, according to the architecture of the frame.
- the leaves slaves are provided on their undersides along a edge, on the one hand, of two known type spring locks, whose bolts can be inserted into strikes performed under the frame, and on the other hand beaten dish projecting outwards, the edge which is opposite comprising at least two anchoring fingers arranged on its underside, perpendicular to said edge.
- the anchor fingers of a leaf, slave or service are blocked under the battered plates of the slave leaves neighbors, those of the extreme leaf taking place in strikes made under the frame.
- a third embodiment when the leaves of a hatch are made in two shaped parts approximately triangular, to each of the two parts of a leaf are welded, on its underside, at least two anchor fingers, one under the edge intended to be placed on the frame sleeping in order to be inserted under a stop horizontal welded to said frame, the other under the edge in diagonal of said part and intended to take place under the corresponding edge of the second part.
- the two parts of a leaf slave are similar, therefore interchangeable, as are two slave leaves.
- the service door has a similar part to those of the slave leaves, and another fitted with a Commander lock, in addition to the exit from a bolt, the exit from the side adjacent to that comprising said bolt, with a finger lock entering into a strike made in the sleeping.
- a hatch locking device includes a frame 1 in the bottom 10 of the rebate from which are inclined planes 11 leading to engravings 12.
- the sleeping frame 1 is intended to receive two slave leaves 2 and a service leaf 3.
- the leaves slaves 2 each have two undersides locking fingers 20 arranged near their edges in contact with the frame and substantially diagonally one compared to each other.
- Service leaf 3 has on its edge outside, arranged on its underside, a lock 30 of known type, and along its opposite edge two fingers anchor 31.
- the closure of the structure is carried out in a first step by sliding the slave leaf 2 at the end on the bottom 10 of the rebate of the frame 1 until the locking fingers 20 take the inclined planes 11 and fit into the engravings 12.
- the slave leaf 2 next and the service leaf 3 are positioned on the frame of frame 1 in the same way, then lock 30 is locked.
- each slave leaf 2 has spring latches on the one hand 21, of known type, arranged near its most edge close to service leaf 3, whose bolts 22 can be engaged in strikes 13 practiced under the frame 1, on the other hand anchor fingers 23 arranged under its opposite edge, and on the other hand still under its edge comprising the latches 21, a battue plate 24, welded to the end of the said edge and overflowing from it towards outside.
- Service leaf 3 has fingers anchor 32 under the edge opposite to that comprising a lock 30.
- the closure of the structure is carried out in a first step by sliding the slave leaf 2 at the end on the rebate 10 of the frame 1, until the anchor fingers 23 engage in strikes 14 formed under the frame 1, then the bolts 22 of the locks 21 are engaged in strikes 13.
- the following slave leaf 2 is then placed on the frame of the frame 1 and by sliding the anchor fingers 23 are engaged under the battue plate 24 of the slave leaf 2 end, then locks 21 are operated and the service leaf 3 is put in place, blocking the assembly.
- the half-slab 33 of the service leaf 3 comprises a lock 30 which, in addition to the operation of a bolt 35, allows the operation of a locking finger 36 positioned perpendicular to the bolt 35, on an edge adjacent to that comprising said bolt 35.
- the half-slabs 25, 26 and 34 each have under their diagonal edge an anchoring finger, respectively 27, 28 and 37 placed under the adjacent half-slab, 26, 25 and 33 respectively, in order to prevent its uprising.
- the half-slabs 34, 25 and 26, which are identical, are secured to the frame, not shown, by fingers 38 which each insert under a stopper horizontal 15 as shown in Figure 1a.
- the slave leaves are interchangeable, this which facilitates their replacement in the event of deterioration, and further facilitates the closure of access to the structure.
