Description

[0001] The described invention relates to a closure device for road installation, which includes a supporting frame and a covering element, such as a closure or cover, connected to the frame by an articulated connection.

[0002] The device is specially designed for installation on road inspection openings (manholes).

[0003] A similar device is known, in which the cover element is connected to one edge of the frame by at least one joint - a sarco, and around which it rotates in the range of a closed position, in which the cover element fits into the circumferential edge of the frame and at least partially rests on the upper surface on the support groove of the frame, and an open position in which the cover element is in a raised position and allows access to the opening of the frame. Such a device is described in patent document EP 06811066 Al.

[0004] The cover element can occupy either an open position that is approximately perpendicular to the plane of the frame and in which the cover element is blocked to prevent it from returning to the closed position around the axis of the joint connection, or an open position that is significantly inclined at an angle of 110 degrees in relation to the plane of the frame.

[0005] However, the joint connection - the hinge and the mechanisms that enable the blocking of the covering element in a raised vertical position, that is, keeping it in an inclined open position at an angle of 110 degrees. they are extremely complex structures and very expensive.

[0006] The described invention aims to eliminate the disadvantages of constructions known up to now.

[0007] For this purpose, the invention provides that, in the device of the entrance opening which consists of a supporting frame and at least one cover element, such as a closure or a cover, which is connected by at least one hinged connection (sark) and mounted so as to rotate along one side of the cover element, from a closed position in which the cover element fits into the circumferential edge of the frame and at least partially rests on the upper surface of the frame groove, to an open position in which the cover element it is in a raised position, so that it is in the joint connection

(hinge) is installed by one cylindrical shaft parallel to the corresponding edge of the frame and which passes through the openings of the joint connection, through two openings located on the upper side of the edge groove of the frame, which are oblong and placed vertically in relation to the edge groove, and two openings located on the inside of the cover element, so that the cylindrical shaft can move freely in the oblong openings of the hinge when moving the cover element from the closed to the open position.

[0008] Also. the hinge openings located on the cover element are also elongated and parallel to the inner surface of the cover element.

[0009] Preferably, the covering element should have two parallel cuts across the thickness of the covering element, which end at the edge of the covering element and perpendicular to it, and so that each cut is located in the same plane with the opening of the joint connection (hinge) on the edge groove, with a width that is greater than the thickness of the corresponding opening of the hinge and a height, measured from the edge of the covering element, that is greater than the height of the opening of the hinge on groove.

[0010] In the closed position of the cover element, both openings of the hinge placed on the groove fit into the notches on the cover element.

[0011] The cover element can be blocked in the raised - open position, when it is located perpendicular to the groove of the frame. and by resting on the groove over the two hinge openings on the groove and the corresponding edge of the frame and the upper edges of the cut when the said two hinge openings reach the end of their travel in them, and in that raised position of the cover element, the axis of the joint link under the effect of the force of gravity rests on the lower edges of the hinge openings placed on the edge groove of the frame.

[0012] The cover element can be blocked in the open position at an angle of 110° by resting the edge of the frame, and that part of the edge that is below the axis of the hinged connection, on the upper parts of the oblong openings of the hinged connection located on the edge groove of the frame. [0013JThe translational movement of the hinge axis relative to the hinge openings is not possible.

[0014] The translational movement of the joint shaft is preferably prevented by placing, on one side of the shaft, one safety clip in the form of a pincer that includes the end of the shaft near one of the joint openings placed on the cover element next to one of the two joint openings on the edge groove of the frame, between which the joint opening of the cover element lies, while the opposite side of the shaft enters the blind hole of the second joint opening located next to the second opening of the joint connections on the edge groove. and from its external side.

[0015] Each joint opening located on the edge groove is of a width less or at most equal to the width of the edge groove itself.

[0016] The openings of the joint connection of the edge groove and the covering element are made in the form of a plate in the shape of a parallelepiped. of relatively small thickness, placed perpendicular to the edge groove and to the covering element.

[0017] The openings of the hinged connection are placed relative to each other with a very small gap in the direction parallel to the corresponding edge surface.

[0018J Each of the covering elements is made in the form of a rectangular plate.

[0019] The invention will be easier to understand, and its other purposes, features, details and advantages will be more clearly expressed during the following description and explanation, which refers to the attached drawings and which are cited exclusively as an example showing one of the methods of application of the invention, where: Figure 1 shows a perspective view of the entrance opening device with a supporting frame and three

panels mounted with an articulated connection on the frame, in accordance with the description of the invention;

Figure 2 shows a view similar to Figure 1, with one of the panels from Figure 1 removed; Figure 3 shows an enlarged view of the lower part of the panel, which is shown raised in Figure 1

position :

Fig. 4 is a three-quarter perspective view, in which the panel from Fig. 1 is shown in

in an open position inclined at an angle of 110° in relation to the frame;

Fig. 5 is an enlarged view of the rounded part marked with V in Fig. 3; and Figure 6 shows an enlarged view of the circled part marked with VI in Figure 2.

[0020] If we look at the pictures, we will see that reference 1. refers to the cover element of the inspection opening (shaft) on the road, which consists of the supporting frame 2., which is installed and attached to the ground, and at least one element for covering or closing 3., such as the shutter or cover, which is attached to the frame 2 with an articulated connection.

[0021] Figures 1 and 2 show three cover elements 3 attached to the frame 2 with a hinged connection, however it is clear that there can be a different number of cover elements on the inspection opening device.

[0022] Each covering element 3. is, if possible. is made in the form of a rectangular plate, which is attached to the frame 2.. by means of a joint connection along side 4. of the cover element 3., on which the joint connection - hinge 5.. is mounted, and which enables the opening to the frame in 2. to be placed in a closed position, during which the panel 3. fits into the corresponding peripheral edge 6. of the frame 2., and at least partially rests on the upper surface 7a. edge groove 7. on the frame 2., or the open position of the opening on the frame 2. in which the plate 3. is in a raised position.

[0023] In the closed position of the frame 2, each of the cover panels 3 rests on the upper surface 7a. of the edge groove 7. on the frame 2. and that with all four corners where, on the inner side, on the shell 8., there are ribbed projections made of cast iron on which are mounted round rubber bands 10. intended for sound dampening, and which rest on the upper surface 7a. edge groove 7. on the frame 2.

[0024] In this closing position of each panel 3, the outer surface of the jacket 8 of the panel touches the outer edge of the peripheral groove 6.

[0025] Each of the cover plates 3. can be placed in two different raised (open) positions, namely the first position which is directly directed to the edge groove of the support 7. and in which the plate is blocked to prevent it from being accidentally folded into the closed position, and the second open position which is under an inclination of 110 degrees in relation to the plane of the opening of the frame 2. and in which the panel 3. rests on the corresponding surface of the peripheral groove 6. frame 2.

[0026] In the closed position of the frame 2, the cover panels 3 are next to each other and are in the same plane.

[0027] The shell 8 of the panel 3 is relatively thin, and therefore it is stiffened by rib reinforcements 9 attached to the inner side of the shell 8.

[0028] One of the end cover panels 3. is equipped with a lock 11. with a cut 12. which goes into the latch 13. on the frame 2. so that, when this panel is in a locked position in relation to the frame 2., the other cover panels 3. are also locked in their closed position in the frame 2., as expected.

[0029] The invention envisages that each joint connection - hinge 5. consists of one cylindrical axis 14. which is placed parallel to the corresponding surface of the peripheral groove 6. on the frame 2. and passes through the openings of the hinge 15. and 16.. which consist of two openings 15. attached to the upper surface 7a of the corresponding part of the edge groove 7. and two openings 16. attached to the inner side of the casing 8. of the cover panel 3.

[0030] Both openings of the hinge 15 on the edge groove 7 have two oblong holes 17 that pass through the width of the openings 15 and which are substantially perpendicular to the edge groove 7.

[0031] The hinge openings 16 of the cover plate 3 have two slits on them, that is, two oblong holes 18 that are parallel to the inner surface of the shell 8 of the panel 3. The oblong hole 18 of one of the hinge openings 16 is placed between the two hinge openings 15 on the edge groove 7 so that it is located next to one of the two hinge openings 15., passes through the entire thickness of the opening of the hinge 16. The oblong hole 18. on the second opening of the hinge 16., placed next to the second opening of the hinge 15. and on its outer side, is a tow.

[0032] The hinge shaft 14 passes through the oblong holes 17 of the hinge opening 15 on the edge groove 7 and through the oblong hole 18 of the hinge opening 16 located between the two hinge openings 15. In addition, the end of the hinge shaft 14 enters the tow oblong hole 18 of the second hinge opening 16 on panel 3, which prevents translational movement of the hinge shaft 14 in one direction relative to the hinge openings 15, 16. (0033) Preventing the translational movement of the hinge shaft 14 in the opposite direction is achieved by means of a safety ring in the form of a pincer 19, which is better seen in Figure 5.. and which includes the end of the hinge shaft 14. at the level of the front surface of the hinge opening 16. with the tow hole 18. and which is located against the front part of this hinge opening which is located next to the front surface of the hinge opening 15. on the groove 7.

[0034] The openings of hinges 15 and 16 are placed in relation to each other so that only a very small gap is left in the longitudinal direction of the joint connection - hinge 5, which is parallel to the corresponding surface of the peripheral groove 6 of frame 2.

[0035] In this way, when opening the cover panel 3 and moving from the closed to the open position of the frame 2, the hinge shaft 14 can move freely in the oblong holes 17 of both openings of the hinge 15 on the edge groove 7. In other words, the axle is "floating" in the openings of the hinge 15 of the edge groove 7.

Each of the hinge openings 15 and 16 is made in the form of mutually parallel plates of relatively small thickness, so that the hinge openings 15 are placed vertically on the upper part of the edge groove 7, and both hinge openings 16 are placed vertically on the inner side of the mantle 8 of the cover panel 3.

[0037] In addition, the width of each opening of the hinge 15 on the edge groove 7 is at most equal to the width of the edge groove 7, so that their edge does not cross the edge of the groove.

[0038] On each of the cover panels 3. there are two parallel cuts 20., which pass through the thickness of the shell 8. of the panel 3. and exit to the edge of the 4. panel, perpendicular to it.

[0039] Each of the cuts, which are generally rectangular in shape, is in the same plane with the corresponding opening of the hinge 15 on the edge groove 7 and is wider than the corresponding opening of the hinge 15. In addition, the height of each of the cuts 20, measured from the edge 4 of the cover panel 3, is greater than the height of the corresponding opening of the hinge 15 on the edge groove 7. Figures 1 and 2 show that in the closed position of the cover panel 3 in the frame 2, both openings of the hinge 15 on the edge groove 7 fit into the two cuts 20 on the panel and do not stand outside them. j0041jIn Figure 3, the representation of the cover panel 3. is blocked in a raised position perpendicular to the edge groove 7. on which the panel 3. rests with its edge 4. In this position, the lower part of the cover panel 3. is blocked between the two openings of the hinge 15. on the edge groove 7. and the corresponding vertical partition of the edge groove 6. of the frame 2., namely the upper sides of the two cuts 20. which at the end of the stroke rest on the two openings of the hinge 15. due to the fact that the height of both cuts 20., measured from the edge groove 7., is less than the height of the corresponding openings of the hinge 15. In this way, the cover panel 3. cannot accidentally return from the vertical position to the closed position on the frame 2. To enable this movement, it is necessary to raise the cover panel 3. in order to open the corresponding hinge openings 15. separated from cut 20., and only then fold the panel 3. into the closed position on the frame 2. j0042] In addition, in the raised, vertical position of the cover panel 3., in which the oblong holes 17. of the hinge opening 15. and 18. of the hinge opening 16. are aligned with each other and vertically with respect to the edge groove 7., the axis of the hinge 14. is supported by the force of gravity on the lower edges of at least the oblong holes 17. of the hinge opening 15. and, if necessary, oblong holes 18. of hinge openings 16.

[0043] Figure 4 shows the cover panel 3. blocked in an open inclined position at an angle of 110 degrees, in which it rests on the corresponding surface of the peripheral groove 6. on the frame 2., namely one part of the edge 4, which rests on the axis of the hinge 14., which again rests on the upper surfaces of the elongated holes 17. of both openings of the hinge 15. on the edge groove 7. In this way, the joint connection, i.e. its shaft 14. and the openings 15. on the edge groove 7., keep the cover plate 3. in the open position at an angle of 110 degrees in relation to the frame 2. In Figure 4. it can be seen that in this position the openings of the hinges 15. partially fit into the corresponding cuts. In order to return cover panel 3 from the open position shown in figure 4 to the closed position on frame 2, it is sufficient to raise panel 3 and place it in a position perpendicular to the edge groove 7, and then lower it to rotate around the joint connection to the closed position on frame 2. It should be noted that cover plate 3 can be placed from the inclined position shown in figure 4 to a vertical position as shown in figure 3., in order to prevent the panel 3. from returning to the closed position on the frame 2.

[0044] The innovative assembly enables, by means of an extremely simple joint connection of the cover element connected to the supporting frame of the opening on the road, the rotation of the cover element from a closed position on the frame to an open position, in which the cover element can occupy a vertical position in which it is blocked in order to prevent its return to the closed position, or an inclined position at an angle of 110 degrees in which it rests on the appropriate surface of the peripheral edge of the frame.
