Abstract
A temporary cylindrical road bollard 1 for lane marking has a fitment portion comprising an annular groove 3 and a foot 4 having a chordal portion 5 removed. The foot 4 can be manipulated past lugs 8 and 9 in a recess 6 of a road stud housing 7. The bollard is then rotated so that remaining circular portions of the foot 4 will be positioned beneath the lugs 8 and 9 to retain the bollard in position. Chordal portions 5 may be cut away on both sides for ease of insertion of the bollard past the lugs and the groove 3 may incorporate stops limiting the extent of rotation of the bollard. <IMAGE>
Description
SPECIFICATION
Improvements relating to temporary road bollards
This invention is concerned with a bollard or delineator post which may be situated on a road to act as a traffic indicator, for example to close off a portion of a road.
It is an object of this invention to provide a temporary road bollard which may be fitted into the housing of a so-called "cats-eye" (Registerd Trademark), which normally incorporates a reflective device, and which is set into the road surface.
Accordingly, this invention provides a temporary road bollard adapted to fit within a housing having a recess with lugs projecting inwardly of two facing sides of the recess, but above the floor of the recess, the bollard comprising a cylindrical body having a fitment portion at one end incorporating a grooved portion leading to a foot part of generally circular form in a plane at right angles to the axis of the bollard and with one or two chordal portions removed, providing one or two linear edges enabling the foot to be lowered below the plane of the lugs by means of the or each linear edge sliding past one or other of the lugs such that, upon subsequent rotation of the bollard through a right angle, circular parts of the foot will lie below the lugs on both sides.
In the preferred embodiment a portion of the fitment part above the groove is shaped so as to contact the inner walls of the other two sides of the recess. This acts to reduce the amount of tipping of the bollard out of the vertical condition. For ease of insertion the foot part may have a chordal portion removed on both sides enabling the foot merely to be dropped past both lugs prior to rotation. Ideally the groove will incorporate stops limiting the extent of rotation of the bollard relative to the lugs. The cylindrical body could be so formed as to provide one or more projections towards the fitment portion and to act as stops for a sleeve slid over the bollard.
The invention may be performed in various ways and preferred embodiments thereof will now be described with reference to the accompanying drawing, in which:
Figure 1 is a side view of one form of temporary road bollard of this invention;
Figure 2 is a view of the bollard of Fig. 1 turned through 90 and positioned within a "cats-eye" housing;
Figure 3 is an underneath plan view of the bollard with the "cats-eye" shown in ghosted outline;
Figure 4 is an underneath plan view of an alternative form of road bollard of the invention;
Figure 5 is a side view of the bollard of Fig.
4; and
Figure 6 is a section on line VI-VI of Fig. 5.
The temporary road bollard shown in Figs.
1 to 3 of the drawings comprises a cylindrical body portion 1 leading to a fitment portion 2 provided with an annular groove 3 and a foot 4. As can be seen from Figs. 2 and 3, a chordal portion 5 of the foot is removed leaving an otherwise generally circular shape.
In use the fitment portion 2 of the bollard is lowered into the recess 6 of a "cats-eye" housing 7 and a tilting movement allows a circular part of the foot 4 to be positioned under the lugs 8 at one side of the recess 6 whilst the linear edge formed by the chordal portion 5 slides down past the lug 9 on the other side of the recess 6. When the bollard is rotated into the condition illustrated in Fig. 3 circular portions of the foot 4 are then located below the lugs 8 and 9 so that the bollard cannot be lifted out.
In a standard "cats-eye" (Registered Trade
Mark) housing the width of the recess 6 as shown in Fig. 2 is greater than the length of this recess so that the vertically extending wall of the part 10 of the fitment portion will touch the end walls 11 of the housing and thus reduce the amount of rocking of the bollard in the direction defined by the length of the recess 6. A further part 1 2 of the fitment portion 2 is tapered where it leads up to the main cylindrical part of the body 1. It will be noted that the cylindrical body 1 carries a pair of projections 1 3 which act to support a sleeve 1 4 slid over the bollard to a desired height.
In the alternative, and preferred, temporary road bollard shown in Figs. 4 to 6 a chordal portion 5 is removed from both sides of the foot 4 which allows the foot to be dropped directly into the recess 6 in the housing 7 without any tilting, the two edges formed by the chordal portions 5 sliding down past the lugs 8 and 9. The bollard will then be rotated so that the remaining circular portions 1 5 of the foot 4 locate beneath the lugs 8 and 9. As shown in Figs. 5 and 6 the circular groove 3 in this instance is formed with stops 1 6 which will locate against the lugs 8 and 9 and thus limit the extent of rotation of the bollard at a position where the remaining portions 1 5 of the foot 4 are securely positioned below the lugs 8 and 9.
1. A temporary road bollard adapted to fit within a housing having a recess with lugs projecting inwardly of two facing sides of the recess, but above the floor of the recess, the bollard comprising a cylindrical body having a fitment portion at one end incorporating a grooved portion leading to a foot part of generally circular form in a plane at right angles to the axis of the bollard and with one or two chordal portions removed, providing one or two linear edges enabling the foot to

Claims (6)
1. A temporary road bollard adapted to fit within a housing having a recess with lugs projecting inwardly of two facing sides of the recess, but above the floor of the recess, the bollard comprising a cylindrical body having a fitment portion at one end incorporating a grooved portion leading to a foot part of generally circular form in a plane at right angles to the axis of the bollard and with one or two chordal portions removed, providing one or two linear edges enabling the foot to be lowered below the plane of the lugs by means of the or each linear edge sliding past one or other of the lugs such that, upon subsequent rotation of the bollard through a right angle, circular parts of the foot will lie below the lugs on both sides.
2. A bollard according to claim 1, wherein a portion of the fitment part above the groove is shaped so as to contact the inner walls of the other two sides of the recess.
3. A bollard according to claim 1 or claim 2, wherein the foot part has a chordal portion removed on both sides enabling the foot to be dropped past both lugs prior to rotation.
4. A bollard according to any one of claims 1 to 3, wherein the cylindrical body incorporates one or more small projections towards the fitment portion end to act as stops for a sleeve slid over the bollard.
5. A bollard according to any one of claims 1 to 4, wherein the groove incorporates stops limiting the extent of rotation of the bollard relative to the lugs.
6. A temporary road bollard substantially as herein described with reference to the accompanying drawings.
