DRIVE FOR A DEVICE FOR CLEANING _ OF REFLECTORS_

The invention relates to a drive for a device for keeping the reflector of a light reflection device for road traffic signs, in particular road guide posts clean, with a changing device for changing dirty ones. Protective or reflective surfaces against corresponding clean surfaces.

In a device of this type known from DE-OS 22 OS 316, a transparent film strip is drawn over the reflection surface and transported further by an electric drive motor if the strip section arranged in front of the reflector is contaminated, so that a new strip section then reaches the functional position in front of the reflector . As a further alternative, a spring motor is proposed for the drive in this laid-open publication. In both cases, you have to intervene from time to time to keep the drive working - with the electric motor, the i

Battery must be replaced and the spring motor must be wound up.

In the case of road traffic signs, which, as is the case especially with road bollards, are widely distributed along the roads, such maintenance work is expensive because the maintenance personnel must travel long distances.

1 year

i] “2 - A AC 060 j I] It is therefore an object of the invention to design a drive of the type mentioned in the introduction in such a way that it does not require such regular maintenance interventions.

'The invention is characterized in that a pendulum motor fed by external ij / air blasts is provided, which has a baffle element attached to the bottom of a vertical pendulum arm, which is positioned against j the passing wind and which with its flapping movements via a stepping switch! ^ direction drives an output element.

The invention makes use of the air blasts which are always to be expected at the place of use and which are caused by vehicles passing by, in order to obtain the drive energy. It takes advantage of the fact that for the changing device, the. yes only has to perform an alternating cycle at larger intervals, a very low energy is required, which can also be applied by a relatively small baffle element with stepping device, even if this is not hit by the air blasts op-ij timal.

| It is also advantageous that such a pendulum motor has only a few and also only mechanical parts, which are also only slightly moved in this application, and can be produced reliably with little effort, so that it can be repaired for years with simple design can be expected.

i]

A design that is built on simply and reliably! can be and aerodynamically has a favorable efficiency is the subject of claim 2.

i; i i: j: With the output element of the pendulum motor, you can directly drive j changing device. This has the advantage that the changeover device is driven as a function of the density of the traffic flowing past, because with dense traffic; In the time unit, more air blows act on the damming element 1 i j than in thin traffic. But instead you can also; .-vH- ·.

• I

- 3 - A 40 060 drive a mechanical accumulator with the pendulum motor, for example a spring accumulator or a gravity accumulator, and from there then call up the drive for an alternating cycle of the changing device from time to time, as is the subject matter of claims 4 and 5; then you have the previously collected energy available for each alternating cycle.

The invention can be used in connection with film strips which are drawn past a reflector as a protective layer, as in the previously mentioned prior publication, or in strips consisting of reflective material, the sections of which, if necessary, come into functional position. However, it is preferred to use the drive in conjunction with stacks of protective plates or reflection plates, which are replaced individually by the change mechanism, as is the subject of claim 6.

The invention will now be explained in more detail with reference to the accompanying drawing.

: The road guide post generally designated 1 according to FIG. 1 | v has a tubular, closed plastic housing with an approximately triangular cross-section. This road guide post is mounted upright next to the carriageway on a road with the side of the road facing the viewer of FIG. 1 facing. Towards the direction of travel, right-hand traffic! provided a rectangular reflector 2, which is arranged behind a rectangular opening 3, while in the direction of travel two further, circular reflectors 4 and 5 arranged one above the other, which are arranged behind corresponding circular openings 6 and 7. The reflectors

• I

- 5 - A 40 060 2, 4 and 5 are formed by the reflecting surface of reflecting plates which are automatically replaced by a changing device which is not visible in the interior of the pile 1 in FIG. In the lower area of the pile, a nozzle 69 is provided which extends transversely through the pile, the two nozzle openings of which, when the pile is in the upright position, are directed towards the gusts of wind by passing vehicles, so that air vortices or air blasts 74 endeavor in one direction or the other through the nozzle 69 pour through hindu chzus.

Figure 2 shows a pendulum motor 31, the pendulum arm 72 drives a stepping device 32. 10 designates a baffle element designed as a baffle plate, which is arranged at the free end of the pendulum arm 72 and is arranged transversely to the axis 75 of the nozzle 69 in the free cross section of this nozzle. The pendulum arm 72 extends vertically and is pivotally mounted in a housing-mounted pendulum bearing 73 with its other, upper end articulated at the rear end of a pump plunger 14. The two nozzle openings 67, 68 are retracted, so that the nozzle cross-section narrows or constricts somewhat from both sides towards the center. The pendulum arm 72 is passed through a passage 70 and extends inside the pile 1, in which the other parts of the pendulum motor 31 are also arranged.

As a result of the air blasts of passing vehicles, the pendulum arm 72 oscillates back and forth in the direction of the double arrow 71 and causes the pump plunger 14, which is guided in a longitudinally movable manner in a housing-mounted slide bearing 13, to move back and forth in the direction of the double arrow 11. The pump plunger 14 is elastic and has a tooth 15 at its free end with which it engages in the toothing 17 of a gear wheel 16 rotatably mounted on the housing. In the toothing of the gear 16 engages a spring-loaded, housing-fixed locking tooth 18, which serves as a backflow protection. In the event of a - 6 - A 40 060 "" I pumping movement of the pump plunger 14 downward, it grips the I. Detent tooth 18, if the amplitude is sufficient, the next

Tooth of the toothing 17, due to its elasticity,! As indicated by dashed lines, Rann jumps over the next | next tooth of the toothing 17. The toothed wheel 16 is prevented from turning back against the arrow direction 1 $ by the locking tooth 18. The next time the pump tappet 14 moves upward, the toothed wheel 16 moves in the direction of arrow 19 and thereby the ratchet tooth 18 overcomes the next tooth of the toothing 17, and because of its elasticity, as indicated by dashed lines, it briefly withdraws.

ΐ Î The gear 16 is rotated in the direction of arrow 19 by the pendulum movements of the dam member 10. For the sake of clarity, the individual I teeth of the toothing 17 are drawn relatively large; the toothing 17 is actually considerably finer.

The gear wheel 16 drives a bevel gear 53, which in turn, as explained in more detail in the text relating to FIGS. 5 and 6 below, drives the changing device 41. The bevel gear is locked against rotation on the shaft 20 and is against the Kraftwir-; Kung a return spring 33 axially displaceable in the position indicated by dashed lines in] Figure 3. By pushing back the bevel gear 53, this can be disengaged from the changing device 41.

In the block diagram shown in FIG. 4, 21 denotes a baffle element corresponding to the baffle element 10, which drives a step switching device 22, corresponding to the step switching device 32. The output element of the indexing device 22, which corresponds to the shaft 20 from FIG. 2, is designated by 23 and drives a mechanical | see memory 24, for example a spring memory or one

Gravity storage, so pulls a spring or lifts a weight. The energy thus stored in the memory 24 drives an output element 25 which acts on a clutch 26. This clutch 26 is normally in the blocking position, in which the output element 25 and thus the accumulator 24 are held. The clutch 26 can be switched to a drive position in which the output element 25 drives the output element 27 of the clutch 26, which in turn drives a feed element 28 for driving a changing device, for example the changing device 41. The clutch 26 is controlled by a button 29, which is preferably time-controlled and is pulled up by the output element 23. Instead of a time-controlled push-button, an event-controlled push-button can also be provided, for example a push-button that triggers a push-button operation by a contamination sensor due to the contamination measured on the reflector.

The button 29 switches the clutch 26 with its button signal for a change stroke of the controlled changing device into the functional position, so that the changing device, driven by the energy stored in the memory 24, carries out a changing cycle.

According to FIGS. 5 and 6, the road guide post is designated 40 and the changing device is generally designated 41. The changing device 41 is loaded with two stacks 42 and 43 of clean reflection plates. The foremost reflection plate 44 of the stack 42 is in the functional position behind the two superimposed openings 45, 46 and the foremost reflection plate 47 of the stack 43 is in the functional position behind the rectangular opening 48. The openings 45, 46 are removed; - 8 - A 40 060 ι * »i i i speak about the openings 6 and 7 from Figure 1 and the; »Breakthrough 48 corresponds to breakthrough 3 from FIG. 1

Reflection plates have aligned threaded holes and are screwed with them in stacks onto a threaded shaft 50, 51 arranged with a horizontal axis. The two threaded shafts 50, 51 are overhung in a rotating manner in a bearing part 52 fastened to the pile 40 'j' and are over

Bevel gears 53 »54 and the bevel gear 55 rotated by the pendulum motor i 31, with a sense of rotation such that ι due to the threaded screw connection, the reflection plates themselves; forward to breakthroughs 45 and 46 because of. The step switching device 32 is accommodated in the housing 56. The other parts of the pendulum motor 31 are not shown in Figures 5 and 6 aer overview.

The reflection plates lie laterally on a sliding wall 34 or 35 which serves as an anti-rotation device and is fastened to the road guide post 40.

| The foremost, functional position of the reflective plate 44 or 47 then passes with a further feed over the end of the threaded shaft into a discharge position in which, as shown for the reflection plate 58, it can slide down under the force of gravity II and via a deflector 59 in a in the lower part of the

Pile located container 60 is passed. The 3 reflection layers of the reflection plates are on each side, because the side of the plates facing the openings

In the exemplary embodiment according to FIGS. 5 and 6, the reflection plate located foremost in the stack 42 or 43 is in the functional position and is reflected. In modification, as will now be explained with reference to FIG. 7, the -. Leave the foremost reflection plate inoperative and drop it into a functional position in which it is caught. In FIG. 7, the pile is denoted by 66, which has an opening 61, behind which the reflection plate 62 in the functional position is located with its reflection layer facing outwards. The reflection plate 62 is supported on a movable holding element 63, which belongs to the changing device and is connected with a functional arm 64 to the changing device, not shown in FIG. 7, accommodated in a housing corresponding to the housing 56. On the function arm 64 there is also an upwardly angled leaf spring 65 which presses the reflection plate 62 from behind against the edges of the opening 61. During the change process, the holding element 63 is withdrawn so that the reflection plate 62 can fall off and, as in FIG. 5, it reaches a collecting container corresponding to the collecting container 60. At the same time, the previously located reflection plate is released from the stack located above it, which is formed and moved in accordance with the stack 42 from FIG. 5, falls down and is caught there in the functional position by the holding element 63 which has now been moved forward again. The openings at the height of the stack corresponding to the openings 45 ″ and 46 are not provided in the exemplary embodiment according to FIG. 7, but the opening 61 is provided for this purpose. The exemplary embodiment according to FIG. 7 can be carried out with one stack or with two stacks, correspondingly as in FIG 5 and 6. The same provision is then made for the second stack, not shown, in that the foremost reflecting plate is thrown out of the stack, gets into the functional position, is held there and only then gets into the collecting container .
