    Improved safety gutter device
    The present invention relates to a gutter device formed in the ground and intended for housing including electrical cables.
    Such a device currently comprises an elongated chute of substantially U-shaped cross section buried in the ground and a plurality of juxtaposed slabs for closing the chute, resting by their side edges on rabbets or shoulders of the side walls of the chute.
    Such a device can be installed along a railway track to house in the trunking power supply cables or any other electrical network including telecommunication, which chute may have a length of several hundred meters. Generally, one of the slabs juxtaposed to an adjacent slab comprises a through passage made in a portion of its edge transverse to the longitudinal direction of the chute and which is intended for the passage of the fingers of one hand to remove the slab of the chute in the case, for example, of maintenance operations.
    The chute and the closing slabs thereof are most often made of reinforced concrete.
    However, the chute of such a gutter device is closed by simple removable slabs, thus leaving all freedom of action to acts of vandalism on the electrical cables they are supposed to protect.
    Thus, malicious people can remove a closure slab at one end of the elongated chute and cut electrical cables and remove a closure slab at the opposite end of this chute to cut the electrical cables to remove by pulling a long cable length in order to recover the copper of these cables.
    The present invention aims to overcome the above drawbacks by providing a gutter device adapted to receive a securing preventing the opening of slabs and thus theft of electrical cables housed in this device. For this purpose, according to the invention, the gutter device formed in the ground and intended for the housing especially of electric cables, comprising an elongated chute of substantially U-shaped cross-section and at least two juxtaposed closure slabs resting by their edges. lateral on rabbets of the side walls of the chute, is characterized in that it comprises a bolt assembly interposed between the two juxtaposed slabs and can occupy a locking position of the two juxtaposed slabs to prevent their relative lifting.
    Preferably, the latch assembly comprises a lower jaw portion disposed beneath the lower faces of the two juxtaposed slabs extending on either side of the juxtaposed edges of the two slabs, an upper plate secured to the lower jaw portion parallel to that and arranged above the upper face of the end portion of one of the two slabs juxtaposed so as to house this end portion between the upper plate and the lower jaw portion in a relatively small clearance, an upper jaw portion disposed above the upper face of the end portion of the other of the two juxtaposed slabs and a locking member connecting the two jaw portions to each other through a formed passageway through the end portion of the other of the two slabs juxtaposed and maneuverable manually to rap approach the two jaw parts to enclose between them the end portion of the other of the two slabs and prevent their relative lifting.
    Preferably, the upper plate is integral with the lower jaw portion by means of a support leg housed in the passage of the end portion of the other of the two juxtaposed slabs and the locking member comprises a screw through a hole in the upper jaw portion perpendicularly thereto, the support leg and a nut rotatably secured to the support leg.
    Advantageously, the locking screw passes through a groove of the support foot which extends transversely between the juxtaposed edges of the two slabs and the nut is immobilized in rotation during the tightening of the locking screw in two parallel rabbets of the support foot located under the groove parallel thereto, the upper jaw portion assembly, locking screw and nut being movable in guided translation along the groove prior to screwing the locking screw to position the upper jaw portion relative to the end portion of the other two slabs juxtaposed depending on the game that may exist between the two juxtaposed edges of the two slabs.
    Preferably, the passage of the end portion of the other of the two juxtaposed slabs has an elongated U-shape whose connecting edge of the two parallel edges is rectilinear and the upper jaw portion comprises an underlying tenon traversed by the locking screw, housed, in the clamping position of the locking screw, in a conjugate recess of the upper plate and the support leg and resting on two lateral shoulders of the recess arranged above the groove, the tenon being connected to the upper jaw portion by a shoulder brought into abutment on the straight edge of the passage before tightening the locking screw.
    Provision is made to make the locking screw non-removable and which comprises a washer or an indestructible nut integral with the free end of the locking screw.
    The movable upper jaw portion is a U-shaped plate between the legs of which is partially housed the upper plate of rectangular shape in the clamping position of the locking member.
    The lower jaw portion is a substantially rectangular plate extending along its length perpendicular to the juxtaposed edges of the two slabs. The lock assembly is brought to its locking position by introducing it into the U-shaped passageway parallel to the rectilinear edge of this passage and then rotating this assembly to bring it perpendicularly to the juxtaposed edges so as to engage the end portions. two slabs juxtaposed on the one hand between the upper plate and the lower jaw part and on the other hand between the two upper and lower jaw parts. The invention also relates to a device forming a latch for locking end-to-end two slabs juxtaposed closure of an elongated chute of a gutter formed in the ground and which is characterized in that it comprises a one-piece assembly comprising two parallel plates upper and lower connected to each other by a support leg, the upper plate and a portion of the lower plate extending on the same side. . support foot, and another upper plate connected to the one-piece assembly via a screw anchored to the support foot perpendicular to the two upper plates, the other upper plate being disposed above the remaining portion of the lower plate parallel to the latter, the screw being manually operable in a direction allowing the approximation of the other of the other upper plate and the lower plate.
    Preferably, the support foot comprises a groove parallel to the lower plate and through which is engaged the screw anchored to a nut that can be immobilized in rotation in two side grooves of the support foot parallel to the lower plate and located in below the groove. The other upper plate comprises an underlying stud traversed by the screw, engaged in a conjugate recess of the support foot and can bear against two lateral shoulders at the bottom of the recess.
    This recess opens through an end portion of the upper plate secured to the lower plate.
    The distance separating the upper plate and the lower plate is slightly greater than the thickness of each slab. The other upper plate has a generally U-shaped in which can engage an end homeland of the upper plate secured to the lower plate when the other upper plate and the lower plate grip under the clamping action of the screw an end portion of a slab. The invention will be better understood, and other objects, characteristics, details and advantages thereof will appear more clearly in the explanatory description which will follow with reference to the accompanying drawings given solely by way of example illustrating an embodiment. of the invention and in which: - Figure 1 is a perspective view of a portion of a gutter device closed by two slabs juxtaposed according to the prior art; - Figure 2 is a perspective view of the gutter device of Figure 1 provided with a lock assembly of the invention locking end to end two slabs juxtaposed; Figure 3 is an exploded perspective view of the latch assembly of the invention; Figure 4 is a perspective view of the latch assembly of Figure 3 in assembled position; - Figure 5 is a top view along the arrow V of the figure. 4; - Figure 6 is a sectional view along the line VI-VI of Figure 5; - Figure 7 is a top view along arrow VII of Figure 2; - Figure 8 is a sectional view along the line VIII-VIII of Figure 7; Fig. 9 is an enlarged view of the circled portion IX of Fig. 8; - Figure 10 is a perspective view similar to that of Figure 2 and showing the step of inserting the lock assembly of the invention between two slabs juxtaposed; Fig. 11 is a perspective view similar to that of Fig. 10 and showing the latch assembly of the invention in an intermediate position before being moved to its position of Fig. 2; - Figure 12 is a sectional view similar to that of Figure 8 and showing the latch assembly at its locking position between the two slabs juxtaposed without clearance between them; FIG. 13 is an enlarged view of the circled portion XIII of FIG. 12; - Figure 14 is a top view similar to that of Figure 7 and showing the latch assembly at its locking position of the two slabs juxtaposed with clearance between them; - Figure 15 is a sectional view along the line XV-XV of Figure 14; and - Figure 16 is an enlarged view of the circled portion XVI of Figure 15.
    Figure 1 shows only a portion of a gutter device of the prior art, comprising an elongate chute 1 having a substantially U-shaped cross section and consisting of two elements joined end to end 1a, 1b.
    The trough 1 is intended to be buried in the ground and is closed by two juxtaposed slabs 2,3 resting by their lateral edges on rabbets or shoulders 4 of the vertical side walls 5 of the trough 1. The slabs 2,3 are thus juxtaposed in a relationship of contiguity and alignment having their upper faces 2a, 3a located substantially in the same horizontal plane. . .
    In fact, the gutter device is constituted by a greater number of end-to-end elements of the elongated chute and juxtaposed slabs closing the chute. For example, the slender chute 1 may extend for several hundred meters along a railway line and electrical cables may be housed in the chute along it. However, the chute 1 may be intended to house other elements, such as for example water supply pipes, optical fibers in other applications.
    The chute 1 and the juxtaposed slabs 2,3 of the gutter device are preferably made of reinforced concrete, but each slab can be made of cast iron when the gutter is used in vehicular traffic conditions.
    The two slabs 2,3 are juxtaposed by their respective edges 2b, 3b extending transversely to the side walls 5 of the trough 1 so that these edges are in intimate contact with each other or separated from one another. other with play, as will be seen later. At least one of the two slabs 2,3, for example the slab 3, has a passage 6 formed through the end portion of this slab. This passage has a substantially U-shaped opening on part of the transverse edge 3b of the slab 3 and whose straight edge 6a connecting the parallel side edges 6b extends parallel to the transverse edge 3b and recessed thereof.
    The passage 6 is thus shaped to allow the introduction, in juxtaposed position of the two slabs 2,3, fingers of a hand of a person to lift the slab 2 or the slab 3 and remove it from the chute 1 in order to access to electrical cables during maintenance operations.
    Of course, for a chute having a very large number of closure slabs, one of the slabs of each pair of slabs juxtaposed has a passage 6 as shown in Figure 1.
    As explained above, the chute 1 being closed by simple removable slabs 2,3, malicious people have full freedom of action to indulge in acts of vandalism by cutting long lengths of electrical cables housed in the chute after removing slabs from one end to the other of the chute. The invention proposes a technical solution to solve this problem.
    According to the invention, a lock assembly 7 is interposed between two juxtaposed slabs 2, 3 and can occupy a locking position of the two juxtaposed slabs shown in particular in FIGS. 12 and 13 and to which the two juxtaposed slabs can not be raised. one compared to the other.
    The various constituent components of the lock assembly of the invention will be described first with reference to FIGS. 3 to 6.
    Thus, the assembly or locking device 7 comprises a one-piece assembly 8 comprising a so-called lower plate 9 intended to form a lower jaw and a so-called upper plate 10 secured in parallel to each other by a support leg 11 ' extending transversely between the two plates 9,10.
    The upper plate 10 and a portion 9a of the lower plate 9 extend on the same side of the support leg 11, the lower plate 9 having a longer portion 9b extending from the support leg 11 to the opposite of the upper plate 10.
    The two plates 9,10 have a generally rectangular shape with the lower plate 9 of a width less than that of the upper plate 10. This prevents the assembly from falling into the chute during the introduction.
    The support leg 11 comprises a substantially flat wall 12 integral with the lower plate 9 and a barrel body 13 projecting from the wall 12 above the portion 9b of the lower plate 9, the body 13 being connected to the part end of the upper wall 10 below it.
    The body 13 has an internal groove 14 extending from the wall 12 parallel to the top of the portion 9b of the lower plate 9 and which ends opposite the wall 12 by two end walls bent in turn. facing each other 15 of the body 13 to form abutment walls.
    The body 13 further comprises two lateral grooves 16 extending parallel below the groove 14 opposite the portion 9b of the lower plate 9.
    The body 13 also comprises above the groove 14 a recess 17 opening through the end portion of the upper plate 10 projecting from the wall 12 above the portion 9b of the lower plate 9. .. ........................... The recess 17 has in section in a plane parallel to the upper plate 10 a substantially U-shaped elongate and the bottom of this recess is constituted by two lateral shoulders 18 extending parallel just above the groove 14.
    The one-piece assembly 8 is preferably made of rigid metal, such as stainless steel or spheroidal cast iron. The latch assembly 7 also includes a second rigid top plate 19 of generally rectangular shape and having a substantially U-shaped internal cutout opening on one of the longitudinal sides of the top plate 19.
    The upper plate 19 comprises a pin 21 provided with a central bore 22 and which is connected to the rectilinear edge 23 connecting the two parallel edges 24 of the blank 20 and substantially in the middle thereof through a wall of greater thickness 25 having a shoulder 26 extending under the upper plate 19 parallel to the rectilinear edge 23.
    Thus, the tenon 21 is underlying the upper plate 19, that is to say that it is below the lower face of this plate projecting into the cutout 20 from the middle of the edge rectilinear 23 of this cut.
    The upper plate 19 and the pin 21 are made of rigid material, preferably stainless steel. The lock assembly 7 further comprises a locking screw 27 engaging, in assembled position of the upper plate 19 to the one-piece assembly 8 through the bore 22 of the pin 21 housed in the recess 17, the groove 14 and a preferably square nut 28 can be immobilized in rotation in the two side rabbets 16, thus connecting the upper plate 19 to the one-piece assembly 8. The screw 27 thus extends perpendicularly to the upper plate 19 .
    In order to make the connection between the upper plate 19 and the one-piece assembly 8 unmountable, a washer 29 is secured to the lower free end of the locking screw 27 which has a head 30 which can be manually operated through an appropriate key, not shown. For example, the cylindrical head 30 may comprise a flat part 31 then requiring a special key to operate the locking screw 27. Other means may be provided to make the locking screw 27 indestructible. For example, it is possible to use one. NYLSTOP type nut (registered trademark) mounted indestructible at the free end of this screw.
    Figures 4 to 6 show the above described components of the latch assembly 7 in the assembled position to each other. These figures, in particular FIG. 6, show that the locking screw 27 has its head 30 resting on the stud 21 while being embedded in the upper plate 19 and its threaded rod 32 passing through the groove 14 and having its end portion anchored to the nut 28 housed in the two side rabbets 16 in order to immobilize it in rotation, the pin 21 traversed by the threaded rod 32 of the locking screw 27 being shown not supported on the two lateral shoulders 18 of the bottom of the recess 17 in which is engaged this tenon.
    By this assembly, on the one hand the upper plate 19 can be brought closer, by screwing the locking screw 27 through the nut 28, the portion 9b of the lower plate 9 to form two parts of jaws as it is will see later and, on the other hand, the upper plate 19 can be moved in rectilinear guided translation relative to the one-piece assembly 8 by the rod 32 of the locking screw 27 can move along the groove 14 on a race going of the wall 12 at the end of the groove 14 to bear against the two abutment walls 15 of the body 13 preventing the locking screw 27 from escaping from the groove 14. At the assembled position of the assembly forming 7, the upper plate 19 is disposed above the portion 9b of the lower plate 9 parallel to the latter and the end portion of the upper wall 10 having the recess 17 is housed in the cutout 20 of the a upper plate 19 as is clear from Figures 4 to 6.
    The assembly of the latch assembly 7 between two adjacent slabs 2,3 to interlock them, i.e. to prevent their relative lifting, will be described with reference to FIGS. Figures 10 and 11.
    FIG. 10 shows that the lock assembly 7 assembled as shown in FIGS. 4 to 6 is first manually introduced through the passage 6 of the slab 3 by engaging the lower plate 9 in the passage parallel to its straight edge. 6a and at the juxtaposed edge 2b of the other slab 2 until the two upper plates 10 and 19 abut respectively on the two upper faces 2a and 2b of the two juxtaposed slabs 2,3, partly overlapping along these two juxtaposed edges 2b and 3b of these slabs as shown in Figure 11.
    Then, the latch assembly 7 is manually rotated 90 ° by considering FIG. 11 to bring it to the position shown in FIGS. 2, 7 to 9 and at which the upper plate 10 bears on the upper face 2a of FIG. the slab 2 extending perpendicular to the juxtaposed edges 2b, 3b and the other upper plate 19 is supported on the upper face 3a of the slab 3 with the straight edge 23 of the blank 20 extending parallel to the juxtaposed edges 2b , 3b slabs 2,3 and set back thereof. FIGS. 2, 7 to 9 also show that, for two slabs 2,3 joined together juxtaposed, that is to say without play, a part of the upper plate 19 is also resting on the upper face 2a of the slab 2 In addition, the upper plate 19 occupies a position relative to the one-piece assembly 8 to which the locking screw 27 is housed in the groove 14 in the immediate vicinity of the wall 12 of the support leg 11 and the shoulder 26 of the upper plate 19 is supported on the straight edge 6a of the passage 6 in which is housed the support leg 11.
    Figures 8 and 9 show further that the end portion of the slab 2 is disposed between the portion 9a of the lower plate 9 and the upper plate 10 while the end portion of the slab 3 is disposed between the part 9b of the lower plate 9 and the movable upper plate 19 with the locking screw 27 occupying its unlocked position to which its head 30 bears on the tenon 21 and the nut 28 occupies its lower position while remaining partly imprisoned between the two rabbets 16 of the body 13 to be immobilized in rotation. In addition, the lower plate 9 extends along its length perpendicular to the juxtaposed edges 2b, 3b under the slabs 2,3 and on either side of these two edges.
    FIGS. 8 and 9 also show that the distance d separating from one another the portion 9a of the lower plate 9 and the upper plate 10 is slightly greater than the thickness e of the slab 2 so as to leave a clearance relatively weakly related to the manufacturing tolerances of the slabs 2 and 3. Finally, in this unlocked position of the latch assembly 7 between the two juxtaposed slabs 2,3, the pin 21 is housed in the recess 17 without being supported on the two lateral shoulders 18 bottom of this recess.
    To lock the lock assembly 7 between the two juxtaposed slabs 2,3, the operator actuates the locking screw 27 with a key inserted on the head 30 of the screw in the direction of its screwing allowing the nut 28 immobilized in rotation between the two rabbets 16 of the body 13 to move along the locking screw. 27 to, the-high. . considering Figures 8 and 9 until it bears against the bottom of the rabbets 16 under the groove 14 so as to move upwardly the one-piece assembly 8 to the position shown in Figures 12 and 13 to which the plate lower 9 bears on the lower faces 2c, 3c of the juxtaposed slabs 2,3 and the upper plate 10 is offset relative to the upper face 2a of the slab 2 of the relatively small clearance defined between the two plates 9, 10 and the thickness of the slab 2. In addition, in the clamping or locking position of the locking screw 27 shown in FIGS. 12 and 13, the portion 9b of the lower plate 9 and the upper plate 19 enclose the part of end of the slab 3.
    It should be noted that the wall 12 of the support leg 11 is supported on the major part of the vertical edge 2b of the slab 2. Finally, at the locking position of the latch assembly 7, the end portion of the upper plate 10 is disposed in the cutout 20 of the upper plate 19.
    Thus, at the locking position of the latch assembly 7 between the two juxtaposed slabs 2,3, it is impossible for an unauthorized person to lift the two adjacent slabs 2,3 together, thus preventing access to the chute 1. The latch assembly 7 can also be installed between two juxtaposed slabs 2,3 having a clearance j between their respective two transverse edges 2b, 3b up to about 2 cm, as shown Figures 14 to 16.
    Thus, once the lock assembly 7 is installed between the two juxtaposed slabs 2,3 in the position shown in FIG. 2, because of the clearance j between the transverse edges 2b, 3b of the juxtaposed slabs 2,3, the The operator must manually move the upper plate 19 in translation relative to the one-piece assembly 8, whose wall 12 of the support leg 11 bears against the vertical part of the edge 2b of the slab 2 by guided sliding of the rod 32 of the locking screw 27 along the groove 14, which extends transversely to the two juxtaposed edges 2b, 3b of the slabs 2,3, to bring the shoulder 26 of the upper plate 19 bearing on the straight edge 6a of the passage 6 of the slab 3 as shown in Figures 15 and 16. These figures also show that the locking screw 27 is blocked by means of the nut 28 at its position to which the portion 9b of the lower plate 9 and the upper plate 19 constituen t, as for the situation shown in Figures 12 and 13, two jaw parts enclosing the end portion of the slab 3, the portion 9a of the lower plate. . 9 being held in support under the lower face 2c of the slab 2 by the locking action of the locking screw 27 with the upper plate 10 having the relatively small clearance with respect to the upper face 2a of. this slab.
    FIGS. 15 and 16 also show that the rod 32 of the locking screw 27 occupies its end position in the groove 14 resting on the two curved abutment walls 15 for a maximum play] between the transverse edges 2b, 3b of the juxtaposed slabs 2,3 of a maximum value, for example, 2 cm. However, it is understood that for games j less than the maximum play, the rod 32 of the locking screw 27 will occupy a position in the groove 14 intermediate between its two extreme positions shown in Figures 13 and 16. In addition, the part end of the upper plate 19 remains housed in the blank 20 of the upper plate 19 despite the game j.
    By providing a plurality of latch assemblies 7 between slabs juxtaposed with a plurality of juxtaposed slabs closing a chute of a gutter device extending over several hundred meters, unauthorized persons are prevented from lifting relative to each other. the others juxtaposed slabs and, consequently, to access the electrical cables housed in the chute 1 along the latter, especially since the assembly forming a lock disposed between two juxtaposed slabs closes in its locking position on passage of a person's hand between these two slabs. The lock assembly of the invention is of a relatively simple structure, can be easily put in place between two existing juxtaposed slabs of a gutter-free device without a particular tool other than a wrench of the locking screw. this set between the two slabs.
    In addition, this assembly can easily be removed from between the two juxtaposed slabs by loosening the locking screw and then rotating the latch assembly from its position shown in Figure 2 to its position shown in Figure 11 to which the assembly forming a latch can be disengaged from between the two slabs juxtaposed as shown in FIG.
