Description

P34023NLOOYGR Title: Rotatable traffic sign system.
The present invention relates to a rotatable traffic sign system. More specifically the present invention relates to a traffic sign of the type comprising a rod with a traffic sign board mounted thereon. The traffic sign board may display for example detour information, direction information, route information, a speed instruction — like maximum speed or advisable speed - an overtaking prohibition, or any other type of traffic information which is commonly used along a road. In general traffic signs may be static or dynamic. An example of a dynamic road sign is a so called matrix board, in general arranged above a road, onto which information is displayed which can be changed when required. A static traffic sign is a traffic sign displaying information which cannot be changed. In case of for example road works, temporary traffic signs of the static type are frequently used which may display information, directions and/or instructions. Whether or not these temporary traffic signs are valid may depend on circumstances, for example whether or not the road workers are working or resting, whether or not it is rush hour, or any other circumstances. Depending on these circumstances the information displayed on the board is changed between visible to the road user or invisible to the road user, and vice versa. Temporary traffic signs are not only used in relation to road works. Temporary traffic signs are for example also used in relation to events, like concerts, in relation to accidents, as well as for other occasions. Also then it is frequently required to change the information displayed between visible and invisible, or vice versa. Changing the information displayed by a static road sign between visible and invisible is basically done in two manners. The first manner is covering the information displayed by a bag pulled over the board or any other cover placed in front of the information. An example of this is the road sign disclosed in NL-2.011.689. Here the road sign board has two halves, one of the halves being pivotable between an open position showing the information on both halves and a closed position folded up on the other half to hide the information of both halves. The second manner is turning the road sign board away from the road user (out of his field of vision) or in the field of vision of the user. This is in general done manually by turning the board between a visible position transverse to the road with the information facing
-2- the road user and an invisible position parallel to the road with the information facing away from the road, and vice versa. JP3208674U shows an automated version of such a road sign. The invention relates to a temporary static traffic sign using the second manner.
The traffic sign system of JP3208674U has a column inserted into the ground or fixed to the ground. This column is provided with a lower bracket and an upper bracket to support a rod carrying the traffic sign board. The rod is provided at, viewed transverse to the length axis of the column, a distance from the column and parallel to the column. At the lower end of the rod a motor is provided. This motor is attached on the one hand onto the lower bracket and on the other hand to the lower end of the rod. When the motor is rotated, the rod turns around its length axis and consequently the road sign board is turned the same angle as the motor rotates. This construction is heavy, complicated and not very practical in use.
The present invention has as its object to provide an alternative traffic sign system which may be used as a temporary, static traffic sign. A further object of the invention is to provide a traffic sign system allowing the information displayed to be turned into and out of the vision of the road user. A still further object of the invention is to provide such a traffic sign system, which overcomes one or more of the above mentioned disadvantages.
According to a first aspect of the invention, this object is achieved by providing a rotatable traffic sign system, comprising: - a rotating device, comprising a first housing part, a second housing part, and an electric motor having a stator and a rotor rotatable around a rotation axis, - a traffic sign board, - an upper rod, having an upper part carrying the traffic sign board and a length axis, and - a lower rod having a length axis, wherein the first housing part is attached — or configured for attachment - to one of either the upper end of the lower rod or the lower end of the upper rod, whilst the second housing part is attached — or configured for attachment - to the other one of either the upper end of the lower rod or the lower end of the upper rod, such that the length axis of the lower rod and length axis of the upper rod are both aligned with rotation axis, wherein the rotating device is configured to rotate, upon actuation of the electric motor, the first housing part with respect to the second housing part, and wherein the stator is fixed with respect to the first housing part and the rotating device is configured such that the rotor is rotatable with respect to both the first housing part and the second housing part.
-3. According to a second aspect of the invention, this object is achieved by providing a rotating device configured to be arranged between an upper rod carrying a traffic sign and a lower rod aligned with the upper rod; wherein the rotating device comprises: — a first housing part, — a second housing part, and — an electric motor having a stator and a rotor rotatable around a rotation axis; wherein the stator is fixed with respect to the first housing part and the rotor is rotatable with respect to both the first housing part and the second housing part; wherein the first housing part is configured for attachment to one of either the upper end of the lower rod or the lower end of the upper rod, whilst the second housing part is configured for attachment to the other one of either the upper end of the lower rod or the lower end of the upper rod, such that the length axis of the lower rod and length axis of the upper rod are both aligned with rotation axis; and wherein the rotating device is configured to rotate, upon actuation of the electric motor, the first housing part with respect to the second housing part.
Because the rotating device is configured to rotate the rotor, when the motor is actuated, with respect the first housing part as well as the second housing part, the traffic sign system can be constructed as ‘one’ slim elongate rod system with the rotating device in between an upper rod and a lower rod. When installed along a road, the traffic sign system according to the invention may project like a straight single rod in a cantilevered manner from the ground. A column parallel to and overlapping with the rod carrying the road sign board, like is used in JP3208674U, is not required. The slim elongate rod system of the traffic sign system according to the invention, further allows storage of multiple traffic sign systems according to the invention in the back of a truck - like is the case with conventional, not-motorized systems only consisting of a single rod and traffic sign board — without hooking up of the traffic sign systems with each other. The rotating device according to the second aspect allows conventional, not-motorized single rod traffic sign systems to be used. A conventional, not-motorized single rod traffic sign system can simply be retrofitted with a rotating device according to the second aspect by either cutting the conventional single rod into two parts or providing an additional rod part and mounting the rotating device according to the invention in between these two rods. According to an embodiment of the first and second aspect of the invention, the rotating device may be configured to rotate the rotor, when the motor is actuated, through a first angle (around the rotation axis) with respect to the first housing part and through a second angle (around the rotation axis) with respect to the second housing part, wherein the first
-4- angle is different from the second angle.
In this embodiment, the first angle may be larger than the second angle, like at least 10x as large.
According to a further embodiment of the first aspect of the invention, the lower end of the lower rod is configured for insertion into or attachment to the ground.
A so called ground pot may be used.
A ground pot is a device allowing easy mounting of vertical elongate objects, like rods, columns, beams into or to the ground.
A ground pot comprises basically a receiving part with an opening configured to receive the lower end of the elongate object and a mounting part to be anchored to the ground.
The mounting part may be a pointed part to be pierced into the ground or a flange with bolt passages for bolting the ground pot onto the ground.
According to another further embodiment of the first and second aspect of the invention, the rotator is provided with a first screw thread, and the rotating device further comprises a translation member provided with a second screw thread mating with the first screw thread, wherein the translation member is configured to be, upon rotation of the rotor with respect to the translation member: — with respect to the second housing part, not rotatable around the rotation axis, — with respect to the first housing part, rotatable around the rotation axis through an angle which may be smaller than the angle through which the rotor is rotated relative to the translation member, and — with respect to both the first housing part and the second housing part, translationally movable along the rotation axis.
The translation member thus is prevented from rotation with respect to the second housing so that when the translation member rotates with respect to the first housing part, the second housing part rotates to the first housing part as well through the same angle as the translation member does with respect to the first housing part.
The angle of rotation of the translation member with respect to the first housing may be smaller than the angle through which the rotor is rotated with respect to the first housing when actuating the translation member by rotating the rotor.
Rotation of the rotor is transferred for one part - which may be the largest part - in translation of the translation member and for another part - which may be the smallest part - in rotation of the translation member.
According to still another further embodiment of the first and second aspect of the invention, the rotating device may be provided with at least one rail, such as one rail with a helical rail section and a runner, the rail and runner being configured to engage each other whilst allowing the runner to slide along the rail, wherein the pitch angle of the helical rail section is
-5. larger than the pitch angle of the mating first and second screw thread. The at least one rail may be one rail with a helical rail section and a runner, but may also be two or three rails each with a helical rail section and each with a runner, although in case of multiple rails also a single common runner is possible within the scope of the invention. With this further embodiment of the first and second aspect: e the helical rail section may, viewed in circumferential direction around the rotation axis, extend over a range of 80° to 190°, such as about 90° or about 180°; and/or e the rail (or each rail) may have a straight section at both ends of the helical section, the straight sections being parallel to the rotation axis; and/or e the rail {or each rail) may be a slit and the runner a pin extending radially with respect to the rotation axis, which pin may for example have a circular cross-section; and/or + the at least one rail may be part of one of either the translation member or the first housing part, whilst the runner is part of the other one of either the translation member or the first housing part. When the helical rail section extends over about 90°, the road sign board can be rotated to and fro between a position transverse to the road and parallel to the road. When the rail helical section extends over about 180°, the road sign board may be flipped between a position showing the front side of the road sign board to the road users and a position showing the back side of the road sign board to the road users. In this latter case the front side and back side may both be provided with information, but different information on each side. Straight sections at the end of the helical rail sections, provide a lock preventing rotation of the road sign board due to forces, like wind forces, acting on the road sign board. This lock relieves the motor from forces acting on the road sign board.
The rail may be a slit and the runner a pin projecting into the slit. But this may also be the other way around, the rail being a rib and the runner a slotted part engaging around he rib. Further, the rail may be provided on the translation member and the runner may be provided on the first housing part or, the other way around, the rail may be provided on the first housing part and the runner may be provided on the translation member.
-6- According to still another further embodiment of the first and second aspect of the invention, the rotor may comprises a spindle, and the first screw thread may be an external screw thread provided on the spindle.
According to still another further embodiment of the first and second aspect of the invention, the translation member may be cylindrical with a bore, and the second screw thread may be an internal screw thread provided in the bore.
According to still another further embodiment of the first and second aspect of the invention, either the rail or the runner is provided on the cylindrical outer surface of the translational member.
According to still another further embodiment of the first and second aspect of the invention, the rotating device may further comprises a channel extending coincident with the rotation axis and a projection extending coincident with the rotation axis and projecting into the channel, wherein the channel and projection have an about same non-circular cross-section and are configured to allow the projection to move back and forth in the channel, and wherein the channel is provided in one of either the translation member or the second housing part, whilst the projection is provided on the other one of either the translation member or the second housing part.
According to still another further embodiment of the first and second aspect of the invention, the first housing part and second housing part may have a cylindrical shape.
As will be evident, the motor of the rotatable traffic sign system may be operated from a distance. For this purpose, it may be wired or wireless connected to a control unit allowing an operator to rotate the traffic sign board from short or large distance, without it being required to go to walk or drive to each traffic sign system in order to rotate it at location.
The invention will now be further elucidated with reference to the drawings showing an embodiment of the invention. In these drawings: — figure 1 shows a general view of a rotatable traffic sign system according to the invention; — figure 2 shows a general view of a rotating device according to the invention, which can be used in the rotatable traffic sign system of figure 1; — figure 3 shows an exploded view of the rotating device according to figure 2, figure 3A being an exploded view in cross section and figure 3B being a normal exploded;
-7- — figure 4 shows the rotating device according to figures 2 and 3 in three positions, figure 4A showing a first extreme position, figure 4C showing a second extreme position and figure 4B showing in intermediate position in between the first and second extreme position.
Referring to figure 1, a rotatable traffic sign system 1 according to the invention comprises a traffic sign board 3 onto which information 4 is displayed, an upper rod 5 carrying the traffic sign board 3, a lower rod 6, a ground pot 7, and a rotating device 10 according to the invention, which rotating device 10 is shown in perspective view in figure 2. The ground pot 7 comprises a receiving part 8 and a mounting part 9. The receiving part 8 is provided with an opening configured to receive the lower end of the lower rod 6. The mounting part 9 is in this example a pointed part having a star shaped cross-section with 3 or 4 ray member transverse to the vertical length axis.
Referring to figures 3A and 3B, the rotating device according to the invention has a first housing part 11, a second housing part 12 and an electric motor 13. The electric motor may be connected to a battery 31. The electric motor has a stator 14 and a rotor 15. The stator 14 is fixed with respect to the first housing 11, i.e. it is immovable with respect to the first housing, so that when the motor 13 is actuated to operate, the rotor 15 will rotate around its rotation axis 16. The first housing part 11 is configured for attachment to the upper end of the lower rod 6. This can be done for example by inserting the free end 17 of the first housing into the upper end of the lower rod or by inserting the upper end of the lower rod into the free end of the first housing part 11, and fixing the first housing part 11 to the lower rod 6 such that rotation of the first housing part 11 with respect to the lower rod 6 is prevented. The second housing part 12 is configured for attachment to the lower end of the upper rod 5. This can be done for example by inserting the free end 18 of the first housing into the lower end of the upper rod 5 — as is shown in figures 3A and 3B - or by inserting the lower end of the upper rod into the free end of the second housing part 12, and fixing the second housing part 12 to the upper rod 5 such that rotation of the second housing part 12 with respect to the upper rod 5 is prevented.
The rotor is via the member 19 connected to the second housing part 12 in a manner such that the member 19 cannot rotate with respect to the second housing part 12 around the rotation axis. This ensures that rotation of the member 19 caused by rotation of the rotor is
-8- transferred into rotation of the second housing part (and the rod and road sign board mounted on the second housing part). So the second housing part can rotate around the rotation axis with respect to the first housing part. Further, the rotating device is configured such that the rotator can rotate with respect to both the first housing part as well as the second housing part. This allows the rotation angle of the second housing part to be different from the rotation angle of the rotor. According to the embodiment shown in figures 3 and 4, rotation of the second housing part 12 when the member 19 rotates is achieved by means of a projection 20 having, transverse to the rotation axis 16, a non-circular cross section, such as a square or hexagonal cross section. This projection 20 is received in sliding manner in a channel 21 formed in the member 19. Rotation of the second housing part 12 when the member 19 rotates may however also be achieved in different manner.
In the embodiments of figures 3-4, the rotor is provided with a spindle with external screw thread 22 which cooperates with internal screw thread 24 provided in a bore 23 in the member 19. This causes the member 19 to function as a translation member 19 when the motor is actuated to rotate the rotor. The translation member can translate forth and back along the rotating axis 16. Due to the projection 20 being slidable in the channel 21, it is prevented that the motor has to lift the upper rod and traffic sign board when rotating the rotor.
In order to guide the translation member 19 when moving back and forth along the rotation axis 16, a bearing bush 30 is provided, which may for example be from nylon.
The translation member 19 is in the embodiment of figures 3 and 4 provided with a rail in the form of a slit 25 formed in the outer surface of the translation member 19. In the embodiment of figures 3 and 4, 3 said rails are provided, but one rail or more rails like three rails is also possible. This rail 25 has a helical rail section 26. The rail further has a runner 27 which is movable along the length of the rail. This runner 27 is mounted to the first housing part and may be a radial pin 27 projecting into the slit 25. When the translation member is moved in the length direction of the rotation axis 16, this runner will cause the translation member 19 rotate around the rotation axis. This in turn will cause the second housing part 12 to rotate correspondingly with respect to the rotation axis. As the pitch angle of the helical rail section is larger than the pitch angle of the mating internal and external screw thread 22, 24, the rotation of the second housing part 12 with respect to the first housing part 11 will be smaller than the rotation of the rotor 15 with respect to the first housing part 11.
-9- The rail 25 has at both ends of the helical rail section 26 a straight rail section 28 which is parallel to the rotation axis. These straight rail sections 28 allow the translation member 19 to move anly parallel to the rotation axis without any rotation and define each an end position of the second housing part 12 with respect to the first housing part 11. In these end positions, the runner 27 lies in the straight rail sections 28. When in one of the end positions a force is applied onto the traffic sign board to rotate the board around the vertical axis, which force may result from wind, the force is absorbed by the runner in the respective straight rail section so that the motor will not feel this force.
Figure 4A shows the rotating device according to the invention in a first end position, in which the translating member 19 lies close to the motor 13. Figure 4C shows the rotating device according to the invention in a second end position, in which the translating member 19 lies at a larger distance from the motor 13. Both in figure 4A and figure 4C, the runner 27 is located at a straight rail section 28. Figure 4B shows the rotating device in an intermediate position, in which the runner 27 is located at the helical rail section.
