Description

SPECIFICATION Road barriers and road signs The invention relates to road barriers and road signs.

The invention provides a fastening device adapted to fasten a road barrer, a road sign, or the like to a kerb.

Preferably the fastening device comprises a clamp operable to grip a kerb and having means to mount a road barrier, road sign or the like.

The clamp may have a first portion which can be fixed relative to the kerb, and may have a second portion movabie relative to the first portion to abut against a face of the kerb to clamp the kerb between the first and second portions.

The first portion may be fixed relative to the kerb by abutting against another face of the kerb.

The first portion may comprise a first flange and the first flange may have teeth to assist in inserting the flange between the kerb and any adjacent surface material such as tarmac, and/or to cause the first flange to bite into the kerb slightly to improve grip. The first portion may comprise securing means which can be embedded in the kerb or in ground adjacent to the kerb. The securing means may be arranged for insertion through the fastening device and into the kerb or ground. The securing means may be insertable through the fastening device at each of at least two spaced-apart locations.

The securing means may comprise at least one pin. Preferably the securing means comprise at least two steel pins and preferably the pins are of high tensile steel. The second portion may comprise a screw-threaded member rotatable to move it towards and away from the first portion.

The screw-threaded member may be mounted in a second flange which is parallel to the first portion.

The screw-threaded member may have a swivel foot to engage the kerb.

The swivel foot may be toothed or otherwise formed to improve its grip on the kerb, for example, it may be provided with a hardened steel point.

The clamp preferably has at least one socket to receive a road sign or road barrier.

A socket may be attached to the screwthreaded member so that rotation of the socket operates the screw-threaded member.

A pair of sockets may be provided on the clamp, inclined to one another such that when the clamp is in position on a kerb, the sockets are inclined to the vertical to receive the legs of a road barrier or road sign, for example a road barrier or a road sign supported by an inverted Vframe.

The fastening device may include at least one locking device arranged to lock a road sign or road barrier in position in a socket.

The locking device may comprise a screwthreaded member which is screwable into the socket.

The fastening device may be provided with a screw-threaded aperture positioned so that screwing of the locking device into the screwthreaded aperture causes the locking device to abut against the upper surface of the kerb for use in forcing the fastening device off the kerb when it is desired to remove the fastening device.

The invention includes a road barrier or road sign in combination with a fastening device according to the invention.

By way of example, specific embodiments of the invention will now be described, with reference to the accompanying drawings, in which: Figure 1 is a side view of a first embodiment of fastening device according to the invention: Figure 2 is a plan view of the device shown in figure 1: Figure 3 is a view of one end of the device; Figure 4 is a view of the other end of the device; Figure 5 is a perspective view illustrating various uses of the device shown in Figures 1 to 4; Figure 6 is a side view of a second embodiment of fastening device according to the invention; and Figure 7 is a plan view of the device shown in Figure 6.

The device shown in Figures 1 to 5 comprises a channel-like member 10 providing a first flange 11, a second flange 12, and an interconnecting web 13.

The flange 11 has three teeth as best shown at 14 in Figure 4.

The flange 12 has a hole 1 5 therethrough and a nut 1 6 is welded adjacent to this hole to provide a bearing through which a screw-threaded rod 17 is screwed. Mounted at one end of this rod 1 7 is a swivel foot 18 having a toothed or serrated surface 1 9. Welded to the other end of the rod 17 is a socket in the form of a short length of box section 20. The box section 20 has a hole 21 therethrough and a nut 22 is welded adjacent to the hole to provide a bearing for a locking device in the form of a screw-threaded wing bolt 23.

The web 13 also has a hole 24 therethrough and a nut 25 is welded adjacent to this hole. The nut 25 is of a size suitable to receive the wing bolt 23.

Welded to the top of the web 10 is a fabricated metal construction which defines two sockets 26 and 27 which are inclined at 900 to one another, each being inclined at an angle of 450 to the upper surface of the web 13. Each socket is provided with a hole and an adjacent welded nut 28 to provide a bearing for a pair of additional wing bolts 29.

The device is for use with a kerb arrangement such as that shown in Figure 5 in which there will be a line of kerbstones 30 which project upwardly from the edge of a road surface 31, an adjacent paved or tarmac footpath 32 being flush with the upper face of the kerbstones.

To use the device the rod 1 7 is rotated in the anti-clockwise direction to draw the swivel foot 18 back against the flange 1 7. The device is then fitted over one of the kerbstones, the toothed flange 11 being hammered in between the kerbstone and the surface 32 of the footpath. The device is then in a position as shown in Figure 1 and the screw-threaded rod 1 7 is rotated in the clockwise direction, by means of the socket 20, to clamp the swivel foot 1 8 tight against the exposed vertical face of the kerbstone. The teeth 14 and toothed surface 1 9 assist in providing a secure grip on the kerbstone.

The device can then be used in a variety of ways, for example as shown in Figure 5. A road sign 33 having a single vertical support post 34 may be supported in the roadway immediately adjacent to the kerb by inserting the foot of the post 34 into the socket 20 and tightening the wing bolt 23.

Alternatively, a road sign 35, supported on inverted V-frames 36 may be mounted in the roadway immediately adjacent to the kerb by inserting the two legs of one of the frames respectively into the two sockets 20 of a pair of devices according to the invention. The sockets 20 can be rotated until the axis of each socket is at the desired angle to the vertical.

If it is desired to support a road sign, such as that shown at 37 supported on inverted V-frames 38, on the footpath, then one of the legs of one of the frames 38 can be secured in the inclined socket 26 of one device according to the invention, and the other leg of the frame can be secured in the inclined socket 27 of another simliar device.

The devices according to the invention may be used to secure in position any piece of equipment which has a part capable of being fitted within the sockets 20, 26 or 27. The clamps may for example be used to secure in position parts of road barriers, in addition to road signs.

The device according to the invention is particularly suitable for securing in position temporary road signs, such as may be used at roadworks. Once the work is over, the signs can readily be removed by slackening the wing bolts and withdrawing the signs from the sockets. The devices themselves can then readily be removed from the kerb by slackening the swivel foot 18 by rotation of the threaded rod 17 whereupon each device can be lifted clear of the kerb. If the toothed flange 11 is firmly embedded in position, the wing bolt 23 can be screwed into the nut 25 to exert pressure on the top of the kerb and hence drive the web 1 3 upwardly, drawing the toothed flange 11 with it.

The length of the web 1 3 may be made adjustable, to suit different widths of kerb, for example kerbs having widths from 4" to 12".

Alternatively a set of different sized devices may be provided, there being a size of device to suit each size of kerb.

Turning to Figures 6 and 7, a second embodiment of fastening device comprises a generally H-shaped metal plate 40 having a platelike extension 41 which is bent at a right angle to form a downwardly-projecting flange 42.

Triangular gusset plates 43 are welded between extension 41 and flange 42 to keep the flange in position. A rib 44 is welded to plate 40 and extends longitudinally along the plate 40.

The flange 42 has a whole 45 therethrough and a nut 46 is welded adjacent to this hole to provide a bearing through which a screw-threaded rod 47 is screwed. Mounted at one end of rod 47 is a swivel foot 48 having a flange 49 and a hardened steel point 50. At the other end of rod 47 is-a. handle 51 with which the rod may be turned.

Welded to the top of extension 41 is a tubular socket 52. The socket has a hole 53 therethrough and a nut 54 is welded adjacent this hole to provide a bearing through which a screwthreaded rod 55 is screwed. One end of the rod 55 tapers to a point 56 and the other end is provided with a handle 57 for turning the rod.

Provided on the cross-piece of the H-shaped plate 40 are level pairs of holes 58 7-mm in diameter. The holes of each pair are provided either side of the rib 44. In use, two high tensile steel driving pins (not shown) 6-mm in diameter are positioned in one pair of the holes 58, as will be explained. Two holes 59 and a spring clip 60 are provided in the rib 44 so that the two driving pins can be securely stored when not in use.

The device is for use with a kerb arrangement such as that shown in Figure 5 in which there will be a line of kerbstones 30 which project upwardly from the edge of a rod surface 31, an adjacent paved or tarmac footpath 32 being flush with the upper face of the kerbstones.

To use the device, the rod 47 is rotated in the anti-clockwise direction to draw the swivel foot 48 back against the flange 42. The device is then placed across a kerbstone with the swivel foot adjacent the exposed vertical face of the kerb. A pair of holes 58 is then aligned with the joint between the kerb and the footpath and the two steel driving pins are hammered through the holes 58 to iie between the kerb and footpath.

Alternatively the pins may be driven into ground (e.g. tarmac) adjacent to the kerb.

Rod 47 is then rotated in the clockwise direction, by means of the handle 51 to clamp the swivel foot against the exposed vertical face of the kerbstone. The flange 49 and hardened steel point 50 assist in providing a secure grip on the kerbstone.

Rod 57 is rotated anti-clockwise out of the socket 52 and signpost (not shown) is inserted into the socket. The signpost is secured by turning the rod 57 clockwise until it firmly contacts the signpost in the socket 52.

The invention is not restricted to the details of the foregoing embodiments. Although the device is preferably made of metal, the device, may at least in part, be made of plastics material.
