| (54) | Pivoted bridge drainer |
| (57) The drainer consists of four main parts: of a plate (9), a pot (10), a frame (22)
with corner bevels, and of a grate (2). In the plate (9) which has a rectangular shape
and is equipped with a drain opening (14) the rectangular pot (10) is located which
has a circular hole (20) amidst to clamp a dirt pan (21). In the pot (10) a frame
(22) is situated in which a grate (2) is embedded the shape of which equals that of
said frame (22). The rips (7) of said grate (2) are shortened in the middle part on
both ends and on one shorter side of said grate (2) the rip (7) is equipped with a
lock (27) which engages in the cavity (6) in said frame (22). On the second shortened
side of said grate (2) the rip (7) is equipped with pivot hinges (23) in which circular
profiles are made to insert the bar (24) durably by means of which said grate (2)
is joined to the frame (22) on the basis of a pivot hinge (33). On the outer rims
of the pot (10) there is a flange (15) with drain holes (16) and round the circular
opening (14) of the plate (9) a shoulder (3) of the flange is shaped. In horizontal direction the rotation of the permanently joined assembly of the grate (2) and the frame (22) is limited by the maximum extent of ± 15° and the transversal and/or longitudinal displacements of said assembly equal 60 mm at most. The corner bevels of the frame (22) are formed so that they abut on the longer internal wall of the pot (10) with the assembly being regulated to maximun rotation limit of 15°. |
Technical Field
[0001] The invention concerns a pivoted bridge drainer which is one of the ensembles of devices used to drain off the bridges.
State of the Prior Art
[0002] Until now, the solution of vertical rectification of a bridge drainer is known i.e. by making use of equalizing rectification frames which are 10, 15, or 20 mm high, according to the Czech application of invention PV 1955 - 3162.
[0003] Further, the solution of drainer locking up is known in which there are locks in both boundary rips, with said locks engaging in cavities in a frame. Disadvantageously the grate can spring out off the frame easily e.g. if several vehicles are passing over one after another.
[0004] In this device the grate tilting out is not solved and therefore the grate must always be taken out by elevating and located on near-by ground.
[0005] In hitherto known solutions the drainer position could not be regulated after inaccurate embedding or for prospective building modifications. This was due to invariable position of an embedded grate with a frame.
Disclosure of the Invention
[0006] A pivoted bridge drainer consisting of basic parts i.e. of a trough, a pot, a frame with corner bevels, and of a grate.
[0007] The essence of the invention consists therein that a rectangular trough is equipped with a drain opening and in said plate a rectangular pot is located which has a circular hole amidst to clamp a dirt pan. In the pot a frame with corner bevels is placed in which a grate is embedded. Its shape equals that of the frame with the grate rips being shortened at both ends in the middle part of the grate. On one shorter grate side the rip is equipped with a lock which engages in a cavity in the frame whereas on the second shorter grate side the rip is equipped with pivot hinges. In these, circular profiles are made to insert a bar persistently by means of which the grate is joined durably to the frame on the basis of a pivot hinge. On outer rims of the pot there is a flange with drain holes and the flange shoulder is shaped round the drain opening.
[0008] Further, the essence consists therein that the persistently joined assembly of the grate with the frame can rotate in maximum extent of ± 15° in horizontal direction.
[0009] The persistently joined assembly of the grate with the frame can be shifted by 60 mm at most in transversal and/or longitudinal directions. The corner bevels of the frame can be shaped so that they abut on the longer internal pot wall when the assembly is being regulated to the maximum rotation limit of 15°.
[0010] Advantageously, the pot and the frame with the grate are designed so that the frame with the grate can be rotated horizontally and bilaterally up to ± 15° in the pot. The transversal and longitudinal position rectification is limited by the rotation extent i.e. there can be maximum shift of 60 mm.
[0011] The pivoted bridge drainer can be used advantageously in cases where an adjacent kerbstone changes its direction with respect to the longitudinal axis of the carrying structure.
[0012] The device can be used to advantage where the kerbstone edge direction is intended to be changed in future. The proposed device design enables to change the transversal, longitudinal, rotary, or even vertical positions of bridge drainer i.e. if necessary.
Survey of Figures
[0013] In Fig. 1 there is a cross section of the device, in Fig. 2 the ground plan of the device is represented with indication of plan rotation of the grate with the frame.
[0014] In Fig. 3 there is a grate ground plan, in Fig. 4 there is a ground plan of the frame with corner bevels and in the Fig 5 there is a pot ground plan. In the Fig. 6 the pivot hinge detail is represented.
Example on the Invention Embodiment
[0015] The pivoted bridge drainer consists of four main parts: of the plate 9, the pot 10, the frame 22 with corner bevels, and of the grate 2. In the rectangular trough 9 there is a drain opening 14 in which the rectangular pot 10 is located which has a circular hole 20 in its centre. Here the dirt pan 21 for led-off water is located.
[0016] In the pot 10 the frame 22 is situated in which the grate 2 is embedded. The peripheral shape of the grate 2 equals the shape of the frame 22 whereas the rips 7 of the grate 2 are shortened on both ends in the central part. On one of the shorter sides of the grate 2 the rip 7 is equipped with a lock 27 which engages in a cavity 6 made in the frame 22.
[0017] On the second shorter side of the grate 2 the rip 7 is equipped with pivot hinges 23 in which circular profiles are made to insert the bar 24 persistently. In this way the grate 2 is joined durably to the frame 22 on the basis of the pivot hinge 33 and therefore the tilting-out function of said grate is ensured simultaneously.
[0018] On the outer rims of the pot 10 a flange 15 is shaped in which there are drain holes 16. Round the drain opening 14 of the plate 9 the shoulder 3 of the flange is shaped.
[0019] In the ground plan the durably joined assembly of the grate 2 with the frame 22 can be rotated in maximum extent of ± 15°.
[0020] The device can be shifted by 60 mm at most in transversal and/or longitudinal directions with limitation by the rotation magnitude. Therefore, the corner bevels of the frame 22 are shaped so that with the assembly being rotated to the maximum limit of 15°, the corner bevels abut the longer inside wall of the pot 10.
Applicability in the Industry
[0021] The solution according to the invention can be applied for all bridge structure types including directly passed roadways or walkways and railway bridges.
