Abstract

A portable hollow stackable road-marker consists of a light upper portion (2) and a heavy (e.g concrete-filled) base portion (1), the base portion having a lower peripheral margin (5) of axially convex shape, so that if the marker is knocked over it will return to an upright position. The base portion is apertured, so as to permit like markers to be stacked one upon another. <IMAGE>

Description

SPECIFICATION Portable road-marker This invention relates to portable road-markers that are, for example, used to mark temporary lane closures on the motorways, road works, temporary no parking areas etc.
Known forms of portable road-marker consist of a hollow conic or pyramidal moulding of plastics or rubber material with a surrounding base flange; these markers are reasonably light, so as not to damage a vehicle if hit, and ar stackable, one marker nesting within the other. One form of marker is known to have a sleeve of light reflective material over the body.
A drawback of these known markers is that they are easily knocked down, thereby obscuring the attached markings, and sometimes concealing the markings from the road user.
It is an object of this invention to provide a self-righting road-marker.
According to the present invention, a portable road-marker comprises an upper portion and a base portion wherein the marker is hollow, the base portion is heavier than the upper portion, so that the marker has a low centre of gravity, the base portion has a lower peripheral margin of axially convex shape, so that if the marker is knocked over it will return to an upright position, and the base portion is apertured to as to permit like markers to be stacked one upon another.
The advantage of such a self-righting roadmarker is that when knocked over it will return to an upright position and continue to perform its warning or indicative function.
In a preferred embodiment of the invention the base portion is formed from an inner wall and an outer axially convex wall.
The present invention is shown by way of example in the accompanying drawings wherein; Figure 1 is a part-sectional side elevation of a road-marker in accordance with the invention; Figure 2 is a similar elevation of an alternative road-marker in accordance with the invention; Figure 3 is a perspective view of a pyramidal road-marker in accordance with the invention; and Figure 4 is a side elevation of a stacked pair of road-markers in accordance with the invention.
As shown from Figs. 1 to 3, a portable selfrighting road-marker comprises a base portion 1 and an upper portion 2, 3.
The base portion 1 is of heavy construction for example moulded polyethylene, sand filled and plugged after forming. In the embodiments shown in Figs. 1 to 2 the base portion has an inner frusto-conical wall 4 and an outer axially convex wall 5 about an axial hole 5a. The hollow 6 formed between these walls may be filled if desired with concrete or some other heavy material to further weight the base.
The upper portion 2, 3 is of light construction for example blow-moulded polyethylene with a light-weight filler 2 or aluminium alloy frame constructon 3 with a sheet metal sleeve 8 attached. The upper portion 2, 3 can carry a sign 7, or a lamp (not shown). Handholds 9 are provided for ease of handling.
The marker shown in Fig. 3 is generally similar to the markers of Figs. 1 and 2 except that the square cross-section of the marker helps to prevent rotation about the longitudinal axis of the marker when it is knocked over and thereby tends to ensure that on its return to an upright position it has substantially the same orientation as it had prior to being knocked over.
Fig. 4 shows a pair of stacked road-markers according to the invention.
All of the road-markers shown in Figs. 1 to 4 are self-righting due to the axially convex form of the lower peripheral margin of their bases in combination with their low centres of gravity. In the illustrated embodiments the axially convex lower peripheral margins are rounded, but could be for example faceted or ribbed.
1. A portable road-marker comprising an upper portion and a base portion wherein the marker is hollow, the base portion is heavier than the upper portion, so that the marker has a low centre of gravity, the base portion has a lower peripheral margin of axially convex shape, so that if the marker is knocked over it will return to an upright position, and the base portion is apertured, so as to permit like markers to be stacked one upon another.
2. A road-marker as claimed in claim 1, wherein the base portion is formed from an inner wall and an outer axially convex wall.
3. A road-marker as claimed in claim 2, wherein the base portion is formed of a moulded, plastics material having a heavyweight filler.
4. A road-marker as claimed in claim 2 or claim 3, wherein the base portion has an inner frusto-conical wall and an outer axially convex wall about an axial hole.
5. A road-marker as claimed in any of claims 2 to 4, wherein that hollow formed by the inner and outer walls is filled with heavy material.
6. A road-marker as claimed in any of the claims 1 to 5 wherein the axially convex lower peripheral margins of the base portions are rounded, or faceted, or ribbed.
7. A road-marker as claimed in any of the preceeding claims, wherein the upper portion is of a light construction.
8. A road-marker as claimed in claim 7,
