Figure 1 shows the road inspection device such as a door marked with the General position 2. Road inspection unit 2 shown in the projection from the top. Road inspection unit 2 contains a frame 4 polygonal shape, in particular, square or rectangular in shape, at least one blank in this case, the two caps 6.

Rama 4 restricts the opening 10 access, for example, to the underground telecommunications. Rama 4 contains the outer side of the E and the inner side of the I.

Rama 4 forms a plane With a frame that is parallel to the plane of figure 1, in which there is an opening 10 (figure 2). Rama 4 contains a base 12, located in parallel to The plane of C-frame and the wall of 14, passing essentially perpendicular to the plane of C-frame. Thus, a wall 14 limits on the merits of a polygonal surface, which essentially has a square cross section.

Through the frame 4 passes to the Central axis, X-X, perpendicular to the plane of C-frame. In the future, the expression «in the radial direction» and «in the circumferential direction» should be considered in relation to the Central axis of the X-X.

Blind stopper 6 contains a shut-off plate 20, made with the possibility of at least partial closing of the opening 10 and situated in the plane of p-P closing. Shut-off plate 20 contains the outer surface of 22 closing and the inner surface of 24 closing.

Inspection hatch 2 additionally includes a box 30, screw 32 and nut 34 (see figure 4).

Inspection hatch 2 contains at least one hinge 36, made with the possibility of angular displacement plugs 6 about Rama 4 between open position and closed position.

Closed position shown in figures 1-4 and 11. In the closed position blind stopper 6, at least partially overlaps the opening 10, and the plane of the R-R shut-off plate 20 is parallel to The plane of C-frame. In the open position plane R-R-closing shut-off plate 20 is essentially perpendicular to the plane of C-frame. In the open position plug can move between two open the provisions, that is, between the free open position (see figure 14), and lock the open position. In a free open position blind stopper 6 can move between this position and closed position. In locked open position blind stopper 6 cannot move on in its closed position. In the same locked open position plug can lean back in the extreme open (see fig.15), which shut-off plate 20 moves more than 90° relative to its closed position and, for example, leans 110 degrees.

As shown in figure 2-4, hinge 36 contains the first Cam 38C frames as well as the first 38T stub. The first Cam 38C frame has a surface of 40 Cam, made in the form of the cylinder with section in the form of an arc of a circle. This surface is 40 Cam has a concave shape and smoothly integrated with the inner surface of the wall 14. The first Cam 38C frame is completely located within the volume bounded by a wall of 14, and stands out from the wall 14 with the component directed radially to the X-axis X.

Surface 40 Cam contributes to a slight wear hinge during use, and facilitates the passage of 38T plugs into the start time of closing.

First 38T stub is located adjacent to stop hob 20 and forms the edge of the bracket 6. First 38T stub is of the surface of 42 , made in the form of the form of parts of the cylinder-shaped convex profile. This surface 42 forms, for example, the angular sector from about 5 degrees to 15 degrees. First 38T plugs seamlessly integrated with the outer surface of 22 shut-off plate 20.

The first Cam 38C frame and the first 38T stub implemented with the possibility of interaction in the first angular range and shut-off plate 20. This first angular range and extends from the open position, if necessary, taking into account the gap order of 5 degrees, to the locked position and is about 60 degrees to 90 degrees. In all of this angular range and both surfaces 40 Cam and 42 adjoin to each other.

Preferably, as shown in fig.12, the first corner of the range and limited, on the one hand, the open position plugs 6 and, on the other hand, the closed position plugs 6 about Rama 4, forming thus the angle of approximately 90°, if necessary, taking into account gap of about 5 degrees.

As shown in figure 1, when blind stopper 6 is in its closed position, the first 38T is fully enclosed volume bounded by a wall of 14.

Hinge 36 additionally contains the second Cam 44 frame, and the second 44T stub. The second Cam 44 frame is based on 12 frame and passes inside the volume bounded by a wall of 14. The second Cam 44 frame and 44T stub implemented with the possibility of interaction exclusively in the second angular range β plugs 6 about Rama 4, consistent with the provisions of the shut-off plate 20, located between the open and closed positions. In particular, the second angle range β limited to the closed position plate 20 and first intermediate inclined position (see fig.12). This is the first intermediate position corresponds to the slope of plate 20, preferably from 40 degrees to 50 degrees relative to the locked position and, in particular, the slope at a 45-degree, as shown in fig.12. Thus, the angular range of p has a length of 40 degrees to 50 degrees, starting from the closed position.

The angular range of beta and angular range and overlap by at least 10 degrees.

Blind stopper 6 is equipped ledge 46, established perpendicularly to the plane of p-P plate. The second 44T stub has a surface formed by the angle of the projection 46.

The second Cam 44 frame contains the first part of the surface of 48 Cam, as well as the second part of the 49 surface of the Cam. The first part of the surface of 48 Cam is essentially flat and runs parallel to The plane of C-frame. The second part of the 49 surface Cam too is flat and tilted relative to the first part of the surface of 48 Cam. The first part of the surface of 48 Cam interacts with the second 44T stub exclusively in the first partial angular range (1, held from the closed position until the second intermediate position, which differs from the first intermediate position. The first partial angular range 1 corresponds to the angle between the plane of p-P and a plane, constituting about 0o to 15 degrees. The second part of the 49 the Cam surface interacts with the second 44T stub exclusively in the second partial angular range 2, different from the first partial angular range (1, which together make up the second angle range?. Thus, this partial angle range (2 concluded between 15 degrees and 40 degrees -50 degrees and, in particular, between 15 degrees and 45 degrees as shown in fig.12.

Thus, between the closed position (figure 11) and the second intermediate position, that is, in the first partial angular range (1, simultaneously, on the one hand, the first part of the surface of 48 Cam interacts with the surface second 44T stub, and, on the other hand, the first Cam 38C frame interacts with the surface of 42 first 38T stub. Between the second intermediate position and the first intermediate position (fig.12), i.e. in the second partial angular range 2 surface second 44T stub is adjacent to the second part of 49 the Cam surface, and simultaneously surface 42 first 38T stub adjacent to the surface of 40 Cam first Cam 38C frame. The slope of the second part of the 49 surface Cam facilitates the passage on the surface of the second 44T stub during the closing plugs.

Hinge 36 additionally contains third Cam 144 frame and third 144 stub. These third Cam 144 frame and 144 stub interact exclusively in the third angular range γ plugs 6 relative to the frame 4. This third angle range γ entirely outside of the second angular range?. It is limited, on the one hand, the first inclined intermediate position, limiting the second angle range?, and, on the other hand, the open position caps, if necessary, subject to clearance in the order of several degrees. Therefore, the angular range of γ is about 40 degrees to 50 degrees and, in particular, extends 45 degrees, as shown in fig.12. Thus, the angular range of γ and angular range α overlap by at least 40 degrees. In this example of the angular ranges α and gamma overlap each other by approximately 45 degrees.

In this case, the third Cam 144 frame formed surface 146 Cam is located on a ledge 62, and the third 144 stub formed surface 148 formed by the bottom surface of the stub and, in particular, excavation 64 (see below).

According to the invention, cover and frame interacts simultaneously with two pairs of Cam and in a large angular range, preferably components, at least 60° and in this case, reaching 90°, if necessary, considering the above, a possible backlash.

In addition, sunroof 2 anchor 50, made with the possibility of plug-retaining 6 about Rama 4 in the closed position stub and in the direction perpendicular to The plane of C-frame. Preferably supporting 50 contain the first part of the surface of 48 Cam and the free end of the ledge 46. The free end of the ledge 46 adjacent to the first part of the surface of 48 Cam closed plugs 6. Contact between the free end of the ledge 46 and the first part of the surface of 48 Cam is a superficial contact. Preferably, at least from the side of the hinge reference means 50 formed the first part of the surface of 48 Cam and the free end of the ledge 46. Reference position between shutter and frame on the opposite side of the hinge is provided ledge same ledge 46, under the cover, which relies on a horizontal surface, similar to a part of the 48 frame surface.

For this ledge 46 contains flat face surface of 52 parallel to the plane R-R closing, providing stable support stub on the frame.

Road inspection unit 2 also contains tools for 60 retention, made with the possibility of blocking plugs 6 about Rama 4 and lock the progressive movement in The plane of C-frame when blind stopper 6 is in the closed position (see figure 3 and 11).

These funds 60 retention contain ledge 62, still connected with a frame 4, and dredging of 64 done in the internal surface of 24 closing plugs 6. In the closed position plugs 6 ledge 62 comes into 64 and restricts the movement of plugs 6 in the plane of P-P In particular, these funds hold 60 restrict the movement plugs 6 relative to the frame in the direction of forward movement seeking to postpone the stub 6 from 14 wall, connected with a hinge, and prevent, in particular, the contact plugs on the other plug or with the side of the frame 4, which is the opposite of a hinge 36. These funds 60 retention play an important role, in particular in the case when a blind stopper 6 is connected to the frame 4 through Jack, acting on the cover 6 in the direction from the wall 14, associated with hinge 36.

In addition, sunroof 2 contains tools 70 lock, made with the possibility of determining the position of the opening plugs 6 relative to the frame 4. These funds 70 locks allow stub 6 move relative to the frame between the free open position (figure 14), in which the stub 6 can be moved from its open position in its closed position, and locked open position in which blind stopper 6 cannot lean back into the closed position.

This means 70 lock contain neckline 72, located between the first Cam 38C frame and lug 62 (see figure 11 and 12). Neckline 72 limits resistant surface 74, adjacent with the tab 62, and resistant surface 76, adjacent to the first Cam 38C frame. Funds 70 lock contain the relevant resistant surface 78 (see fig.12)located on the stub 6. When blind stopper 6 is the neckline 72 and when it move in its closed position, resistant surface 78 pressed against the hard surface of 74, preventing stub.

In addition, the outer surface of 22 plugs 6 contains deepening 79, made with the possibility of at least partial hours in him hard surface 76, allowing, thus, stub 6 achieve far open position in which blind stopper forms an angle of about 110 degrees relative to its closed position (fig.15).

Preferably frame 4 does not include counter-bevel in the direction perpendicular to The plane of C-frame. Similarly, blind stopper 6 does not contain in the direction perpendicular to the plane of the R-R closing.

Plug 6 is executed from pig-iron. Preferably at least one 38T, 44T, 144 and preferably all are in the form of a single detail and, in particular, at the same time with blank 6.

Plug 6 above road checking device can be disconnected from the frame 4 any of its closed position through a gradual move the caps in the direction perpendicular to its plane of p-P, any of its open position through a gradual move the caps in the direction essentially parallel to the plane of P-P Installation of plugs 6 on Rama 4 you can also perform when blind stopper 6 is in a horizontal or vertical position.

Preferably frame 4 and plug 6 can be used in conjunction with not shown Jack lifting, made with the possibility of turning the cover 6 in its open position. To ensure the attachment of the Jack on the frame 4 is an insert 30. Box 30 fixed on the frame 4 by hanging 62 and the first Cam 38C frame (see figure 3-6). Box contains 30 ledge 80, runs parallel to the protrusion of 62. Ledge 80 bridge contains 82, next to a ledge 62 in the assembled state. This bridge 82 forms a surface plug-retaining 6 relative to the frame during phases of opening and closing plugs, when Jack strive to push the door to the side of the frame, located opposite the hinge. For this stub contains thorn 84 (see figure 9), which nestles on the bridge 82, by limiting the movement of plugs 6 to the side of the frame 4, which is the opposite of a hinge 36. In addition, considering that spike 84 comes between the ledges 62 and 80 during movements opening and closing plugs 6, it also provides direction plugs 6 during her rotation, limiting, in particular, move plugs 6 in the direction parallel to the wall 14, associated with hinge 36. In addition to restrict the movement of plugs 6, when she is in the closed position, in which the thorn 84 is not between the tabs 62 and 80, preferably in the cone 6 perform an additional pin 85. This additional thorn 85 shifted thorn 84 and in the closed position rests on the side of the ledge 62, located opposite inserting 30.

In addition, the box contains 30 mounting hole 86 intended for attaching the Jack.

Box 30 also contains surface 90 retention (see figure 10), done in keeping insert 30 relative to the frame 4 in the direction perpendicular to The plane of C-frame and directed outside.
