Abstract

The cover consists of a surrounding frame (5) and a hinged lid (7). The hinge is equipped with a cam (29) which interacts with a counter-cam (22) on the frame to align the adjacent edges of the lid and frame when the lid is closed. The lid and frame also have interacting lateral guide surfaces, and the lid has an anti-lift pin (30) on each side adjacent to its hinge to prevent its hinge end from lifting when closed.

Description

The present invention relates to a road system of the type comprising a first part forming a support frame, and a second part removable forming a crowning element, articulated tilting on the frame along a hinge bank by at least one hinge.

The invention is particularly applicable to mouths absorption for curbs, and will be described below in the context of this app.

The object of the invention is to reconcile a great ease of molding of parts with, in position closure of the crowning element, the presence a minimum space between the hinge edge of this element and the adjacent hinge edge of the frame. This last property makes it possible to avoid the creation, along the articulation bank, of a cavity able to trap a female shoe heel and clogged with gravel and sand. We understand that such clogging makes the opening operation difficult and does not guarantee the opening angle, clearly greater than 90 °, which is necessary for the stability of the crowning element in the open position maximum.

To this end, the subject of the invention is a road system of the aforementioned type, characterized in that the hinge comprises a cam integral with one of the two parts and a cam follower integral with the other part, this cam and this cam follower being adapted to cooperate together so as to bring said edge of the hinge edge adjacent to the frame when of the closing movement of the crowning element.

The road system 1 shown in Figure 1 is an absorption mouth installed on the edge sidewalk, at the border between sidewalk 2 and a floor 3. It consists of four main rooms made of ductile iron, each moldable without core except of its locking members, described below. These four parts are a support frame 4, a extension 5 and two crowning elements which can be opened by tilting: a grid 6 and a pad or slab 7. The device also comprises three adjustment members 8 height of the extension, each consisting of a bolt 9 and three nut washer sets 10. The frame 4 has two parts, namely a support lower 11, embedded in the roadway, and a support upper 12, embedded in the edge of the sidewalk.

The riser 5 is arranged above the support 12. As seen in Figure 3, it has in plan, a general U-shape, with, at the end free from each branch and in the middle of the soul, a boss perforated 13, which is superimposed on a perforated boss analog 14 of support 12.

To set up the extension, we take into sandwich each boss 13 between the head of a bolt 9 and an assembly 10, and the underlying boss 14 between two sets 10. The degree of tightening of the nuts of the two sets 10 lower allows the adjustment of the height and height of the riser.

Extension 5 (Figures 3, 5, 6 and 7) includes internally, over most of its circumference, a horizontal flange 15 for supporting the buffer, in the form of strip, which runs along a peripheral bank 16 projecting towards the top. The bank 16 has a middle portion 16A, the along the core of the U, and two lateral parts 16B. In each inner corner of the U, this collar forms a widened range 17 of roughly square shape, which presents a through rectangular opening 18 in its corner outside. A horizontal plate 19 is provided at plumb and above opening 18. One of the two plates 19 present, in its edge adjacent to the shore 16A, a slot 20 with edges parallel to this bank, from inside the U.

The edge of each beach 17 which is at the opposite of bank 16A also covers its entire length a projection 21 directed upwards. The part of this projection which is not adjacent to the opening 18 has a ramp 22 on the bank 16A side inclined downwards and towards this bank and whose generators are horizontal.

Buffer 7 (Figures 2, 4 and 7) has essentially a plane veil 23 of general shape rectangular, with a notch on each side rectangular 24 open laterally and on the bank 25 of articulation. Under the veil 23 a rib protrudes 26 and two elastic snap-in fingers 27, adapted to snap into reliefs 28 of the enhances (Figure 3).

The thickness e of the edges of the tampon (Figure 4) is slightly less than the width l of the slot 20 (Figure 6). The largest width L1 of the buffer (Figure 2) is equal, to within a clearance, to the distance which separates the two lateral edges 16B of the extension, while its smallest width L2 (Figure 2) is equal, to a clearance close, at distance D (Figure 3) which separates the facing edges of the two plates 19.

Under the veil 23, in the area of small width L2, protrude two hinge elements, namely, for each of them, a circular sector 29 with an axis parallel to the bank 25 and a pin 30, roughly cylindrical , also of axis parallel to this bank. The sectors 29 are both coaxial and contained in planes perpendicular to the bank 25, and the pins 30 are coaxial with one another and project outwards on the corresponding sectors 29. The outer wall of one of the two sectors (the upper sector in FIG. 2) is coplanar with that of the corresponding edge of the pad, while the outer wall of the other sector 29 is set back a small distance, typically of the order of a centimeter, relative to the outer wall of the corresponding edge of the tampon. However, the pin 30 associated with the latter sector 29 is longer than the other by the same distance, so that the two pins 30 protrude laterally by the same length l 1 relative to the web 23 (Figure 2).

To put the tampon in place on the raises, we have its web 23 in a vertical plane, and it is inclined, in this plane, towards slot 20. Its bank can then enter this slot while the pawn 30 adjacent is placed under plate 19. When the shore of the buffer abuts at the bottom of the slot 20, it is possible to straighten the buffer, while maintaining the sail in the same vertical plane, and thus bring the other pin 30 below the level of the other plate 19.

At the end of this turnaround, bank 25 is resting on the flange 15 of the core of the U, and pushes the pad sideways to penetrate the second aforementioned pawn 30 (the top pawn in Figure 2) under the corresponding plate 19. Sectors 29 are not then not in contact with the ramps 22 of the riser.

To close the buffer, it is tilted around its bank 25. This movement brings the sectors 29 into contact with the ramps 22, then, because of their profiles, the cooperation of these members progressively pushes the bank 25 towards the adjacent bank 16A of the enhancement. In the closed position, locked by the members 27-28, as shown schematically in Figure 8, there is thus a minimum clearance along the edge 25, and the only substantial space between the buffer and the extension is formed by the slot 20, whose area may be of the order of cm ² . The risks of fouling and trapping of the heels of female shoes are therefore eliminated.

It should be noted that during the entire movement closing, the notches 24 cooperate with the edge inside of the plates 19 for laterally guiding the buffer. It is the same when you open the tampon at more than 90 °: in this case, the top of the web 23 cooperates with the upper edge of the bank 16A, and the pins 30 advance under the plates 19 until they stop against the projections 21 for a buffer opening of 110 to 120 °, giving it a stable opening position maximum. There is no risk of the buffer closing unexpectedly.

The presence of the pins 30 allows on the one hand to set the maximum opening position of the buffer, as explained above, on the other hand to avoid any extraction untimely of this room. Indeed, to extract the tampon, it must be placed with its vertical veil 23, then perform the complex movements in reverse described above for its installation on the riser.

Grid 6 is articulated in the same way on the lower support 11 of the frame. The directions of openness of this grid and the buffer are indicated by arrows F6 and F7 in Figure 1.
