Definitions
- the present invention relates to a retractable road device that can be used, for example, for closing a manhole.
- FIG. 1 represents a known retractable road system bearing the reference 1 and comprising a guide frame 2 coming to be mounted on the concrete chimney 3 of a manhole to be closed and a guided frame 4 with a covering element, not shown, such as a buffer, the guided frame 4 being intended to cooperate with the guide frame 2 during assembly of the frame 4 to cover element on the look.
- the road device 1 is retractable in that, in the assembled state, the frame 4 with covering element, which must be substantially flush with the surface of the roadway, fits more or less deeply into the guide frame 2 as a function of the height of the reservation or rabbet 5 in which this set is housed and retained after filling the reservation 5 of a mix.
- the frames 2, 4, which each have a generally annular shape, are each provided with a cylindrical extension respectively 6, 7 from material, the extension 7 of the frame 4 extending, in the assembled state , in the extension 6 of the guide frame 2.
- This known road system has the disadvantage of requiring a relatively large depth of reservation, usually of about 310 mm, so that it can not be used in shallower chimney reservations, such as 130 mm. used to receive a single frame with a covering element.
- the object of the present invention is to overcome the above disadvantages of the known road system by proposing an upgradeable road device that can be adapted to different heights of chimney reservations in which it must be integrated.
- the retractable road device of the type comprising a frame of a covering element, such as a buffer, which can be housed in a reservation of a chimney of a look of roadway to closing, and a means that can cooperate with the frame to position the latter relative to the chimney so that in the assembled state, the frame is substantially flush with the surface of the roadway, is characterized in that the positioning means of the frame comprises a skirt attached to the frame, extending downwardly thereof and whose section of the outer peripheral surface corresponds to the free section of the opening of the chimney to allow the skirt to be housed in the opening of the chimney to a position relative to the latter.
- the skirt is removably fixed by snapping into a crown of the frame.
- the skirt comprises at least two radially outer pins that can snap elastically respectively into two retaining cavities formed in the ring of the frame.
- each lug is constituted by a curved free end of an elastically deformable tab cut in the wall of the skirt along a generatrix of this skirt.
- Each lug is located near the circular edge of the end portion of the skirt engaging in the crown of the frame. In the recessed position of the skirt in the crown of the frame, the circular edge of the skirt rests on the underside of an internal collar of the frame.
- the crown comprises, at its inlet opening, a frustoconical peripheral surface flaring downwards and allowing the pins to be elastically offset radially inside the skirt during the introduction of its end portion into the front crown. that they can be anchored elastically in the two retaining cavities of the crown.
- Each lug comes resiliently supported on a shoulder retaining the cavity in the recessed position of the skirt in the crown.
- the skirt is made of sheet steel and of generally cylindrical shape and has a predetermined height allowing a position adjustment of the frame relative to the chimney according to the height of the reservation.
- Figure 1 shows a longitudinal section of a retractable roadway device according to the prior art
- Figure 2 is a longitudinal sectional view showing a retractable road device according to the invention
- FIG. 3 is an enlarged partial side view along the arrow III of Figure 2;
- the retractable road device 10 comprises a frame 11 for receiving a covering element, not shown, such as a buffer or cover, and intended, for example, to come up on the concrete chimney 12 with a view of the road to be closed.
- a covering element not shown, such as a buffer or cover
- the frame 11 and its covering element are substantially flush with the surface of the roadway.
- the frame 11 has a relatively low height, for example about 100 mm and can be housed in a reservation 13 with a depth of about 120 mm to 230 mm as will be seen later.
- the frame 11 is mounted on a substantially cylindrical skirt 14 removably attached to the frame by snapping into a ring 15 so that the skirt 14 extends downwardly the frame 11 coaxially with it.
- the skirt 14 comprises in the present case four radially outer pins 16 which can snap elastically respectively into four retaining cavities 17 formed internally in the ring 15 of the frame 11.
- Each lug 16 may be constituted by a curved free end a lug 18 cut in the wall of the skirt along a generatrix thereof, the lug 16 being located near the circular edge of the end portion of the skirt 14 engaging in the crown 15 of the frame 11.
- Each tab 18 is elastically deformable radially to the skirt 14.
- the ring 15 of the frame 11 comprises at its entrance opening directed towards the bottom of the frame a frustoconical peripheral surface 15a flaring downwardly from the frame and allowing elastically radially to be withdrawn inside the skirt 14 the lugs 16. during the introduction of the corresponding end portion of the skirt 14 in the ring 15 before these lugs 16 can be anchored elastically in the respective holding cavities 17 of the ring 15.
- the curved end of each lug 16 is elastically resting on a shoulder or retaining lip 17a delimiting the lower part of the cavity 17.
- the circular edge of the skirt 14 located near the lugs 16 is in abutment on the lower face 19a of an inner collar 19 of the frame 11, this face being opposite the flange 17a to delimit circumferentially with the latter the cavity 17.
- the skirt 14 has its outer peripheral surface having a section corresponding to the free section of the opening of the chimney to allow the skirt 14 to be housed in this opening at a position relative to the chimney.
- the diameter d of the opening of the chimney 12 may be about 615 mm and the outer diameter of the skirt 14 may then be about 608 mm.
- the skirt 14 has a predetermined height such that once introduced into the opening of the sleeve 12, it allows a height adjustment of the frame 11 relative to the chimney according to the height of the reservation 13
- a skirt 14 with a height of approximately 140 mm allows adjustment in position of the frame 11 in the reservation 13 for heights of reservation 13 in the range that has just been defined.
- the skirt 14 is made from a steel sheet.
- the mounting of the skirt 14 to the frame 11 is very simple since it suffices to turn the frame 11 on the ground so that it has its crown 15 directed upwards and, after angular positioning of the skirt 14 relative to the ring 15, to push the skirt 14 into the ring 15 so that the free ends of the lugs 16 are spaced elastically radially inwardly of the skirt 14 by the frustoconical surface 15a until that the lugs 16 engage elastically respectively in the holding cavities 17. Then, the user returns the frame assembly 11 and skirt 14 to introduce the latter into the opening of the inspection chimney 12 to adjust it to its position relative such that the frame and its cap member is housed in the reservation 13 substantially flush with the surface of the roadway.
- the frame 11 provided with the skirt 14 is temporarily suspended in two parallel bars 20 (shown in phantom in FIG. 2) resting on the ground in order to maintain centrally the frame assembly 11, a crowning element. and skirt 14 in the reservation 13 and at a level such that the frame 11 and its crown element are substantially flush with the surface of the roadway, this suspension technique being known per se.
- the frame 11 and its cap element is then held in the reservation 13 by a mix introduced into the reservation and compacted according to the usual technique after removing the two suspension bars. It should be noted that the skirt 14 prevents the mix from falling into the opening of the chimney 12.
- the skirt 14 may comprise a number of lugs 16 different from four, at least two lugs 16 diametrically opposed being sufficient to retain the skirt 14 in the ring 15 of the frame 11.
- Figure 4 shows that the four lugs 16 are arranged symmetrically with respect to a longitudinal median plane 14 of the skirt with two lugs 16 closer to this plane than the other two.
- the four lugs 16 can simply be regularly spaced around the skirt 14.
- the skirt 14 remains fixed to the frame 11, it can be removed from this frame by disengaging the pins 16 from their respective holding cavities 17 to, for example, replace it with a other skirt in better condition.
- the device of the invention can be used to replace a different road device mounted in a reservation of a pre-existing chimney without having to break the concrete of this chimney to adapt the reservation to the device of the invention since it adapts of itself to any reservation whatever its height.
- the skirt may have a section other than circular, for example rectangular, or have a frustoconical shape.
