Description

REGISTRATION FOR ROAD WITH ARTICULATED COVER ON A FRAME DESCRIPTION OF THE INVENTION The object of the present invention is essentially to provide a road or similar register which essentially comprises a frame embedded in the road to emerge with it and on which a stopper is hingedly mounted. Road registers of various types have already been proposed, among which must be mentioned those that comprise a frame or armor in the form of a quadrilateral on which are articulated complementary triangular plates in the shape of a right triangle that constitute the plug that allows the sealing of the opening constituted by the frame. However, in these known road records with triangular or even non-triangular plates that constitute the stopper, the plates are generally heavy and difficult to lift and, furthermore, these are hinged on two opposite sides of the frame, which makes it uncomfortable or even difficult to access the frame, ie the introduction of material, such as pipes or cables, into the REF: 24823 trench or the hole in the road whose opening is delimited by the frame. Thus, the present invention aims to remedy these drawbacks by proposing a road registration where opening and closing with the lid are particularly facilitated, and that, in the open position of the lid, a decoupling is ensured and thus a easy and immediate access to the ditch or hole in the road, through the frame, without being disturbed, under any circumstances, by the open lid. For this purpose, the invention has for its purpose a road registration comprising a frame in the form of a quadrilateral on which are articulated complementary triangular plates in the shape of a right triangle, which constitute the cap for closing or closing the frame, characterized in that said plates triangular are articulated on two or three adjacent sides of the frame, in open position of the plates, to leave a free access to the frame on two sides or a side respectively. As it is understood, the free access to the frame will be clearly facilitated by the fact that two adjacent sides of the frame will be devoid of articulated plates.

According to another characteristic, the register of this invention comprises two triangular plates, respectively articulated by one of its straight sides on two adjacent sides of the frame. According to another characteristic, the register of this invention comprises four triangular plates, namely two plates respectively articulated by one of their straight sides, on two opposite sides of the frame, and two other plates juxtaposed with one of their straight sides, and articulated on its other side straight on one of the other two opposite sides of the frame. According to yet another feature of the invention, each triangular plate articulated on the frame, except one, is provided with at least one protruding leg cooperating with the lower part of an adjacent plate. It will even be specified here that the triangular plate, which does not include the aforesaid leg, is provided with a system for blocking or crossing this plate on the frame. As it is already understood, due to the presence of the mentioned legs, the blocking of the plate alone, not including the leg, will allow the blocking of all the others. But other advantages and features of the invention will appear better in the following detailed description, and refers to the accompanying drawings, given only by way of example, in which: Figure 1 is a top plan view of a frame with a lid constituted by two triangular plates according to this invention, illustrated in closed position; Figure 2 is a very schematic and perspective view of the road record of Figure 1, shown in the open position; Figure 3 is a top plan view of a road record with a lid of four triangular plates, according to another embodiment; Figure 4 is a very schematic and perspective view showing the road record of Figure 3, in the open position; figures 5 and 6 illustrate, in partial section, the articulation of a plate on the frame, this articulation being represented for a closed position of the cover (figure 5), and for an open position thereof (figure 6); Y Figures 7 and 8 illustrate in section, respectively in locked and unlocked position, the bolt associated with one of the plates of the lid.

With respect to the figures, a frame 1 is observed capable of delimiting an opening made, for example, on a road, this frame having the shape of a quadrilateral on which are articulated complementary triangular plates in the shape of a right triangle, which constitute the cover of sealing of the frame 1. According to the embodiment illustrated by figures 1 and 2, two triangular plates 2, 3 in the form of a right triangle and capable of being juxtaposed, in their closed position, are hinged on the frame 1 by their hypotenuse 4. According to an essential characteristic of the invention, the two triangular plates 2 and 3 are articulated on two adjacent sides the, Ib of the frame 1. More precisely, the plate 2 is articulated by two articulations 2a on the side of the frame 1, just as the plate 3 is articulated by two joints 3a on the side Ib of the frame 1, adjacent to the side la. As can clearly be seen in figure 2, when the triangular plates 2 and 3 are open, a very easy access is made to the trench where the opening is delimited by the frame 1, since the adjacent sides le and Id will be advantageously decoupled. It is even observed in FIG. 2 that one of the triangular plates, namely the plate 2 according to the example shown, includes a leg 5 projecting from this plate, and capable of cooperating with the lower part, that is to say the face 3c of the plate 3 that includes a bolt 6, which is well observed in figures 7 and 8, and which allows the steel to be rolled or blocked on the frame 1. It is therefore understood that, starting from the open position of the visible register in the 2, it is convenient to close this register, first lowering the plate 2 on the frame 1, and then the plate 3 that taking support on the leg 5 of the plate 2 stems the latter, after which the bolt 6 is activated. of the plate 3 to finally lock the cover constituted by the plates 2 and 3 on the frame 1. It will be noted here that the plate 3 does not include the protruding plate 5. In the embodiment illustrated by figures 3 and 4, the frame 1 which is advantageously a m single-block arc that comes from casting, all like frame 1 in the embodiment described above, has a rectangular shape and not substantially square, like that which is the previous case. On this frame 1 four triangular plates 10, 11, 12, 13 on three adjacent sides Id, la and Ib of the frame 1 are articulated. More precisely, the plates 10 and 13 are articulated respectively thanks to the articulations 10a, 13a and by one of its straight sides on two opposite sides Id, Ib of frame 1, these two sides constituting Id, Ib the small sides of the rectangle forming said frame. The other two plates 11, 12 are each articulated by the hinges 12a, on their other straight side, on one of the other two opposite sides of the frame 1, the sides of which are the large sides of the frame. rectangle that forms said frame. It is clearly seen in Figure 3 that the triangular plates 10 and 11 are capable of being juxtaposed by their hypotenuses 14 just as the plates 12 and 13 can be juxtaposed by their hypotenuses 15, while the plates 11 and 12 articulated on a same side of frame 1, can be juxtaposed by a straight side 16. As can be seen very well in figure 4, the plates 10, 11 and 12 are each provided with a protruding leg 5, while the plate 13, which does not have it, is on the contrary provided with a bolt 6. In this way, according to the same principle as previously explained with reference to figures 1 and 2, starting from the open position visible on figure 4, to close the record just described, will descend successively and in order, plates 10, 11 and 12 that will auto-close thanks to the legs 5. The plate 13 is then lowered and locked on the frame 1, which also allows the locking of the other plates 10, 11 and 12. In this way, the closing procedure of the registration is carried out successively lowering the plates 10, 11, 12 and 13 in the opposite direction to that of the clock hands, while the procedure of opening the record will be carried out in the opposite direction, that is to say unlocking or removing the bolt and first opening the pla ca 13, then successively opening and in order plates 12, 11 and 10. In this regard, it will be noted that the procedure of opening successive plates in one direction, and closing these plates in the other direction will be advantageously of a nature to facilitate the operations on the work for a worker, even not dragged, and who is facing a plurality of plates to open or close. Returning to figure 4, it is observed that in the open position, an important decoupling is made at the large side of the rectangle that forms the frame, in such a way that the access of the hole or the trench and the deposit of material to through the frame, it will be particularly easy and fast. The articulation of the triangular plates in the form of a right triangle on the frame 1, which is the plates of the embodiment of figure 1 or of the variant of figure 2, is of a type known per se, and will be briefly described with respect to FIGS. 5 and 6. Each plate, for example, the plate 2 is provided with an ear or the like 20 receiving a shaft 21 integral with the frame 1. The ear 20 includes a spout 22 which, in the open position of the plate 2 (figure 6) can be housed in a recess or similar 23 provided in the frame 1. In this way, starting from the closed position of the plate 2 visible in figure 5, to open this plate, it is made to pivot according to the direction of the arrow F and the peak 22 is received in the hollow 23, which keeps the plate 2 positively in the open position. To close the plate 2, a slight lifting of this plate will be carried out, in order to uncouple the spout 2 from the recess 23, and this will then be lowered against the frame according to a direction inverse to that of the arrow F. It has been shown in FIG. the feet or the like belonging to the plate 2 and allowing the support of this plate in closed position on the frame 1. The locking system associated with the single plate of the frame 1, which does not include the leg, will also be described succinctly. projection 5, that is to say the plate 3 visible on the figures 1 and 2 or the plate 13 visible on the figures 3 and 4. In the figures 7 and 8, it is observed that the bolt 6 associated with the aforementioned plate, for example the plate 3, essentially comprises a rotor 30 rotatably mounted on the plate 3 and aided by a spring 31. To this rotor 30 is associated a latch or the like 32 which can cooperate with a rib 33 of the frame 1. Starting from the visible fastened position in the 7, it will be sufficient, with the help of a key 34, to cause the rotor 30 to undergo a rotation of a quarter turn, for example to uncouple the latch 32 from the frame 1, and thus perform the locking of the plate 3, as shown in FIG. it observes very well in figure 8. Of course, the invention is not nullly limited to the described and illustrated embodiments that have been given by way of example. It is so that the triangular plates in the shape of a right triangle could constitute a different number from that described, with the proviso that these plates are articulated only on certain adjacent sides of the frame, in order to be uncoupled in the open position of the register, on the other side or the other adjacent sides of the frame. This invention thus comprises all the technical equivalents of the means described, as well as their combination, if these fall within the scope of the following claims.It is noted that in relation to this date, the best method known by the applicant to carry out the aforementioned invention, is the conventional one for the manufacture of the objects to which it relates. Having described the invention as above, property is claimed as contained in the following:
