Description

The present invention relates to a device for the circulation path comprising a support frame and an end element, such as a cover or cover, mounted pivotally mounted on the frame.

The invention applies in particular to a road registration opening.

A device of this type is known according to which the end element is mounted pivotally mounted on the frame along an edge of the end element at least by an articulation hinge between a closing position in which the element of The finish is inscribed on a peripheral flange of the frame to be applied at least partially on an upper face of a frame seat recess and an opening position in which the end element is straightened to access the opening of the frame. Said device is known from EP 0681066 A1.

The closing element can occupy either a straightened opening position substantially perpendicular to the plane of the frame and in which the closing element is locked to prevent it from accidentally tilting to its closing position of the frame, or an opening position substantially overturned to 110 degrees with respect to the plane of the frame.

However, the articulation hinge and the means that allow the closing element to be locked in its substantially vertical straightened position or kept in its opening position turned substantially at 110 degrees has an extremely complex and expensive structure.

The present invention aims to avoid the above drawbacks of the devices for known traffic lanes.

To this end, according to the invention, the device for circulation paths comprising a support frame and at least one end element, such as a cover or cover, mounted pivotally mounted on the frame along an edge of the element of closing by means of at least one articulation hinge between a closing position in which the closing element is inscribed in a peripheral flange of the frame to be applied at least partially on an upper face of a frame seat recess and a opening position in which the closing element is straightened, is characterized in that the articulation hinge comprises a cylindrical axis substantially parallel to the corresponding flange of the frame and which crosses openings of articulation hinge rings comprising two integral hinge rings a the upper face of the frame recess and whose openings are oblong holes substantially perpendicular to the r drip and two hinge rings integral to the inner face of the end element, so that the cylindrical axis can move freely in the oblong holes of the hinge rings of the recess during the tilting of the end element between its closing positions and frame opening.

Advantageously, the openings of the hinge rings of the end element are oblong holes substantially parallel to the internal face of the end element.

Preferably, the end element has two parallel notches that cross the thickness of the end element leading to the edge of the end element perpendicular to it and each notch is located in the same plane as a hinge ring of the recess, and has a width greater than the thickness of the corresponding hinge ring and a height, from the edge of the end element, greater than the height of a recess hinge ring.

In the closing position of the closing element, the two hinge rings of the recess are inserted respectively in the two notches.

The closing element may be locked in its straightened opening position, supported substantially perpendicular to the latter and between the two hinge rings of the recess and the corresponding flange of the frame by the upper edges of the two butt notches respectively on these two hinge rings and in this straightened position of the end element, the articulation shaft is supported by gravity on the lower ends of the two oblong holes of the recess hinge rings.

The closing element can be locked in its straightened opening position substantially 110 ° in support on the frame flange by its edge part supported under the butt joint axis on the upper ends of the oblong holes of the two hinge rings of recess

The articulation axis is immobilized in translation with respect to the articulation hinge rings.

Preferably, the axis of articulation is immobilized in translation, on the one hand,

by a clip in the form of a clamp that surrounds a part of the end of this axis in the

proximity of one of the hinge rings of the closing element adjacent to one of the two hinge rings of the recess between which the hinge ring of the closing element is located, and on the other hand, on the opposite end of the axis of joint inserted into a blind hole of the other hinge ring of the end element adjacent to the other hinge ring of the recess outside the latter.

Each recess hinge ring has a maximum width equal to the recess width.

The hinge rings of the recess and the end element are each constituted by a substantially parallelepiped block of relatively small thickness that extends perpendicularly to the recess and the end element.

The hinge rings are arranged relative to each other according to a very small play in a direction parallel to the corresponding wall of the flange.

Each auction element consists of a rectangular panel.

With reference to the figures, the reference 1 designates a device for a roadway that forms a road inspection opening comprising a support frame 2 intended to be sealed on the floor and at least one closing or closing element 3 , such as a cover or cover, mounted articulated with tilting on the frame

2.

Figures 1 and 2 show the presence of three auction elements 3 mounted articulated on the frame 2, but of course the circulation device can comprise a different number of these.

Preferably, each closing element 3 is constituted by a rectangular panel mounted articulated with tilting on the frame 2 along an edge 4 of the closing element 3 by an articulation hinge 5 between a closing position of the corresponding opening of the frame 2 in which the panel 3 is inscribed in a corresponding peripheral flange 6 of the frame 2 to be applied at least partially on an upper face 7a of a seat recess 7 of the frame 2 and an opening position of the frame 2 in which the Plate 3 is enraged.

In the closed position of the frame 2, each end panel 3 is applied on the upper face 7a of the seat recess 7 by its four corners and which comprise cast iron pins that protrude from the internal face of the plate 8 and are provided with anti-noise rubber washers 10 that come to rest on the upper face 7a of the seat recess 7.

In this closed position of each panel 3, the outer face of the plate 8 of this panel is level with the upper edge of the peripheral flange 6.

Each closing panel 3 can occupy two straightened opening positions, an opening position substantially perpendicular to the seat recess 7 in which the plate 3 is locked to prevent it from accidentally tilting to its closing position and an opening position substantially overturned to 110 degrees with respect to the plane of the opening edge of the frame 2 and in which the panel 3 is supported on the corresponding wall of the peripheral flange 6 of the frame 2.

In the sealing position of the frame 2, the closing panels 3 are juxtaposed with respect to each other and in the same plane. The plate 8 of each panel 3 has a relatively small thickness and is

stiffened by ribs 9 integral to the inside of the plate 8.

One of the end panels 3 is provided with a latch 11 with latch 12 that cooperates with a lock 13 of the frame 2 so that in a locked position of this panel to the frame 2, the other panels 3 are also immobilized in their closed position in frame 2, as it is known.

According to the invention, each articulation hinge 5 comprises a cylindrical axis 14 substantially parallel to the corresponding wall of the peripheral flange 6 of the frame 2 and which crosses articulation hinge rings 15, 16 comprising two hinge rings 15 integral with the face upper 7a of the corresponding recess part 7 and two hinge rings 16 integral to the internal face of the plate 8 of the closing panel 3.

The two hinge rings 15 of the recess 7 respectively comprise two oblong holes 17 which cross according to their thickness the hinge rings 15 and which are substantially perpendicular to the recess 7.

The two hinge rings 16 of the cover plate 3 comprise two holes that may be constituted by oblong holes 18 substantially parallel to the inner face of the plate 8 of the panel 3. The oblong hole 18 of one of the hinge rings 16 , located between the two hinge rings 15 of the recess 7 adjacent to one of these two hinge rings 15, crosses in its thickness the hinge ring 16. The other hinge ring 16 arranged adjacent to the other hinge ring 15 on the outside of the latter has its oblong hole 18 blind.

The articulation shaft 14 passes through the oblong holes 17 of the two hinge rings 15 of the recess 7 and the oblong hole 18 of the hinge ring 16 located between the two hinge rings 15. Furthermore, the end part of the articulation shaft 14 it is inserted in the blind oblong hole 18 of the other hinge ring 16 of the panel 3 to immobilize in one direction the articulation axis 14 with respect to the hinge rings 15, 16.

The translational immobilization of the articulation axis 14 in the opposite direction is carried out by a clip-shaped clip 19, more visible in Figure 5, which surrounds the end part of the axis 14 at the level of the face of the hinge ring 16 with through blind hole 18 and opposite the face of this hinge ring adjacent to that of the hinge ring 15 of the recess 7.

The hinge rings 15, 16 are arranged relatively one with respect to the others so that they only allow a very small play to remain according to the longitudinal direction of the articulation hinge 5 parallel to the corresponding wall of the peripheral flange 6 of the frame 2.

Thus, during tilting of the closing panel 3 between its two sealing and opening positions of the frame 2, the articulation shaft 14 can move freely in the oblong holes 17 of the two hinge rings 15 of the recess 7. Said of another mode, this axis is mounted floatingly on the hinge rings 15 of the recess 7.

Each of the hinge rings 15, 16 is constituted by a substantially parallelepipedic block of relatively small thickness such that the hinge rings 15 extend perpendicularly to the upper face of the recess 7 and the two hinge rings 16 extend perpendicularly of the internal face of the plate 8 of the closing panel 3.

In addition, each recess hinge ring 15 has a maximum width equal to the width of the recess 7 so that it does not overflow from this recess.

Each closing panel 3 has two parallel notches 20 that cross the thickness of the plate 8 of the panel 3 leading to the edge 4 of this panel perpendicular to the edge.

Each notch, generally rectangular in shape, is located in the same plane as a corresponding hinge ring 15 of the recess 7 and has a width greater than the thickness of the corresponding hinge ring 15. Furthermore, each notch 20 has a height, from the edge 4 of the closing panel 3, greater than the height of the corresponding hinge ring 15 of the recess 7.

Figures 1 and 2 show that in the closed position of each closing panel 3 in the frame 2, the two hinge rings 15 of the recess 7 are respectively inserted in the two notches 20 of the panel without protruding outside the latter.

Figure 3 shows that the closing panel 13 is locked in its straightened position perpendicular to the recess 7 on which the panel 3 is supported by its edge 4. In this position, the lower part of the closing panel 3 is locked between the two hinge rings 15 of the recess 7 and the corresponding vertical wall of the peripheral flange 6 of the frame 2 by the upper edges of the two notches 20 butt respectively on the two hinge rings 15 because the height of the two notches 20 from of the recess 7 is less than the height of the corresponding hinge rings 15. In this way, the closing panel 3 cannot accidentally swing from its vertical position to its closed position of the frame 2. To allow this tilting, it is necessary to lift the closing panel 13 for releasing the notches 20 of the corresponding hinge rings 15 and then tilting the panel 3 to its frame closing position

2.

In addition, in the vertical straightened position of the closing panel 3 in which the oblong holes 17 of the hinge rings 15 and 18 of the hinge rings 16 are aligned with respect to each other vertically with respect to the recess 7, the axis of articulation 14 is supported by gravity on the lower ends of at least the oblong holes 17 of the hinge rings 15 and, where appropriate, of the oblong holes 18 of the hinge rings 16.

FIG. 4 shows the closing panel 3 which is locked in its position turned substantially at 110 degrees in support on the corresponding wall of the peripheral flange 6 of the frame 2 by its edge part 4 supported under the articulation axis 14 butt on the upper ends of the oblong holes 17 of the two hinge rings 15 of the recess 7. Thus, it is the articulation shaft 14 and the hinge rings 15 of the recess 7 of the articulation hinge which retain the end plate 13 in its position overturned substantially at 110 degrees outside frame 2. Figure 4 shows that in this position the two hinge rings 15 are partly inserted through their respective notches. To bring the closing panel 3 to its closed position of the frame 2 from the overturned position of Figure 4, it is sufficient to lift the panel 3 to place it in a position substantially perpendicular to the recess 7, and then swing it towards its position of closing of the frame 2. It should be noted that the end plate 3 can be brought to its substantially vertical position of Figure 3 from its overturned position of Figure 4 to prevent the return of the panel 3 to its closed position of the frame 2 .

The device of the invention allows, by an extremely simple conception of an articulation hinge between an end element and a roadway opening support frame, the end element can be tilted from its frame closing position to a position of opening of this frame, either substantially vertical in which the closing element is locked to prevent it from returning to its closing position, or turned substantially at 110 degrees on the corresponding wall of the peripheral flange of the frame.
