Description

Delineating Means for a Pathway and/or Road and a Method of Use Thereof This invention relates to delineating means for a pathway and/or road and a method of use thereof.

Although the following description refers almost exclusively to cyck lane delineating means for defining and/or separating a cyck path or lane from a vehicle lane on a road, it wifl be appreciated by persons skilled in the art that the present invention could be used to delineate any pathway, roadway, highway and/or the like on which a vehicle, bicycle, user transportation device and/or pedestrian may travel in use.

Cyclists are particularly vulnerable to traffic related accidents, which can often be fatal, due to the proximity in which vehicles travel with respect to cyclists on a road. In an attempt to overcome this problem, many roads are provided with clear designated cycle lanes for sole use by cyclists. However, these cycle lanes are typically only defined by painted markings on the road and since there is no physical barrier separating the cycle lane from the vehicle lane, it is often the case that vehicles drive and/or drift into these cycle lanes, thereby still posing a significant accident risk to cyclists. In some instances, in an attempt to overcome this problem, cycle paths have been provided, which are either clearly delineated from the roadway using concrete islands or curbing, or which are moved onto a pedestrian walkway to share with the pedestrians. In the former case, this requires a permanent change to the road layout, thereby incurring significant cost, time to fit the delineation means and/or the like. In the latter case, delineation of the pathway into a pedestrian section and a cycle section is still typically undertaken by painting markings onto the pathway and such markings are often ignored by pedestrians and/or cyclists, thereby posing a potential accident risk to both the cyclists and pedestrians. It will be appreciated that other user transportation devices, such as roller skates and the like pose similar problems and there is therefore a need for delineation means that allows the separation of one form of vehicle or user from another form of vehick or user on a pathway or roadway.

Tt is known to provide delineation devices that are formed from rubber or p'astic rather than concrete in an attempt to overcome some of the abovementioned problems. One example is a curb device formed from rubber that is joined in an end to end arrangement to form an elongate curb arrangement to delineate different sections of a roadway. Cylindrica' channe's are provided on the rear of the curb device to allow attachment of the device to a roadway in use. Part of a front surface of the curb device has an angled planar surface. Ihis curb device is designed to form an island arrangement which is then in-filled with concrete, thereby making it a permanent structure. As such, it suffers from many of the abovementioned problems. In addition, it is often the case that the front surface of the curb device facing the bike lane is of such a height to create a step such that a cyclist can actually crash into the same or clip the same when cycling, thereby posing an accident risk in its own right to the cyclist. This could lead to a cyclist falling off their bicycle into a vehicle lane, thereby increasing the accident risk to a cyclist.

It is therefore an aim of the present invention to provide delineation means for use on a road\vay, pathway and/or the like that overcomes the abovementioned problems.

It is a further aim of the present invention to provide a method of using delineation means for use on a roadway, pathway and/or the like that overcomes the abovementioned problems.

According to a first aspect of the present invention there is provided delineation means for use on a pathway or roadway for dividing the pathway or roadway into sections, said delineation means including a body portion having at kast a basc for ocation on a ground or floor surface in use, a front wafl, a rear wall, and a top surface or edge, and wherein at least part of an outcr surface of thc front wafl is substantiafly concave or inward'y curved in shape at, adjacent to, or towards at kast the base or a base edge thereof.

By providing at least a lower section of the front wall of the delineation means at, adjacent to or towards the base, that is substantially or wholly concave or inwardly curved in shape, this provides a relatively smooth transition or gentle change in angle of surface from the ground or floor surface Ofl which the delineation means is used to a top surface or edge of the delineation means, thereby removing or reducing the likelihood of a road or path user, such as a cyclist for example, from hitting an edge of the dclineation means and having an accident.

This is in contrast to prior art devices that typically provide or define a step or upright planar surface on a front wall of a delineation device that could result in a road or path user, such as a cyclist from hitting the same and falling off.

The sections of the pathway or roadway at least partially separated by the delineation means can have different uses, be of different dimensions and/or thc like.

In one embodiment the front wall is typically arranged so as to facc or be directly adjaccnt the SCCtiOfl of thc road or pathway which is to be used by a pedestrian, a cyclist, a relatively smaller vehicle compared to a vehicle that may use the section of the roadway or pathway facing the rear wall, and/or which is opposite to the rear wall that faces a major roadway section.

in one embodiment the rear wall is typically arranged to face or be directly adjacent a road or a section of the pathway or road that a vehicle, such as a car, lorry, motor bike, motorised vehicle, relatively large vehicle and/or the like may use in use.

Preferab'y the substantiaUy concave or inwardiy curved part of the front wall runs from a front and/or base edge of the delineation means towards a front and/or top edge of the delineation means.

Preferably the front and/or base edge of the front wall is of such a depth/height or is flush, substantially or almost flush, or relatively flush with the ground or floor surface on which the delineation means is used with respect to the size of the vehicle wheel, bike wheel, transportation wheel, pedestrians foot and/or the like with which the delineation means is trying to reduce the likelihood of accident or impact therewith. For example, the depth or height of the front/base edge is 2cm or less, and preferably 1cm or less.

In one embodiment an upper part of the front wall of the delineation means is convex, substantially convex or outwardly curved in shape. The upper part in one example is between midway of the front wall and an upper edge of the front wall adjacent the top surface or edge.

In one embodiment a lower part of the front wall of the delineation means is concave, substantially concave, or inwardly curved in shape and an upper part of the front wall of the delineation means is convex, substantially convex or outwardly curved in shape. Thus, in this embodiment, at least part of an outer surface of the front wall is convex, substantially convex or outwardly curved in shape at, adjacent to, or towards the top surface or edge. The convex portion typically prevents a user from travelling too high up the front wail, such as for example on a bicyde.

Preferably a relatively smooth transition is provided between the tower concave or inwardly curved part of the front waU and the upper convex or outwardly curved part of the front waif This avoids the provision of any upright, shoulder or step portion on the front wall which may result in a road or path user, such as a cyclist, from impacting the same and having an accident.

The curvature of the lower concave section of the front wall typically provides a gradual change in gradient and can be at an approximate angle of 0-45 degrees adjacent the lowermost edge of the front wall. In one example, the gradient change of the convex section of an upper section of the front wall is approximately 0-45 degrees.

In one embodiment at least part of the rear wall of the delineation means is vertical, substantially vertically arranged, upright or at a relatively steep angle with respect to the horizontal axis or base of the delineation means. This allows a clear step arrangement to be formed or associated with the rear surface of the delineation means in relation to a wheel of a vehicle, thereby preventing, or at least reducing the likelihood of, a vehicle wheel from travelling over the delineation means in use.

Preferably the steep angle or angle of the rear wall is between 45-90 degrees with respect to a horizontal axis or a base of the device. (3

In one embodiment the delineation means has one or more end walls. The end walls can be substantially vertical, perpendicular or upright with respect to the base of the delineation means.

This allows adjacent delineation means to be provided end to end in an abutting or spaced apart r&ationship. Afternativ&y, one or more end wafls can be shaped in a simflar manner to the front \vall. This allows an end wall of the delineation means to offer the same advantages as the front wall in terms of providing a gentle non-step Hke gradient. iAdternatively still, one or more end walls can have a convex curvature.

Preferably attachment means are provided on or associated with the delineation means to allo\v the delineation means to be attached or detachably attached to a ground or surface in use.

Ihe attachment means could include any or any combination of one or more apertures, channels, recesses, slots, adhesive, welding, inter-engaging members, screws, nut and bolts, and/or the like.

In one embodiment the attachment means are provided on or associated with a front wall of the delineation means. For example, one or more channels can be defined in the delineation means to have an opening in the base and/or in the front wall.

This can allow one or more bolts and/or the like to be passed through the channels for attachment to a ground surface in use.

In one embodiment the attachment means are provided on or associated with a top surface or edge of the delineation means.

In one embodiment a plurality of attachment means are provided on or are associated with the delineation means and each of said attachment means is provided a spaced distance apart on the body portion of the delineation means.

Preferably cover means are provided on or associated with the attachment means so as to prevent dirt, debris, water, snow and/or the like from getting into the same. The cover means in one cxampe can indude one or more caps, movab'y mounted or removabk caps that fit over the openings of one or more channels in use.

Tn one embodiment the delineation means is formed from a single piece of material. For example the delineation means could be molded or cut out from a rubber material, wooden material, metal material, plastic material, and/or the like.

Aiternatively, the delineation means coffid be formed from any or any combination of rubber, wood, metal, plastic, concrete, aggregate and/or the like. The material can be recycled material in one example, such as for example recycled rubber. This significantly reduces the cost of forming the device and makes the device more environmentally friendly.

Preferably the delineation means is formed from a substantially solid piece of material or material. however, the body portion of the delineation means could be hollow or have hollow sections (i.e. have one or more cavities) therein if required.

In one example, an opening of the hollow or cavity section or sections is defined in the base or faces towards the surface on which the device is located in use. Preferably at least rhe edges defining the hollow or cavity opening has a degree of flexibility to allow the device to be used on uneven surfaces.

Preferably one or more of the materials used to form the delineation means has a degree of flexibility to the same. This allows the delineation means to be used on uneven surfaces and/or the like.

In one embodiment light reflective material or means is provided on or associated with one or more walls, edges or surfaces of the delineation means, thereby increasing the visibihty of the same to a user.

In one embodiment one or more indents, recesses, troughs, protrusions and/or the like can be provided on or associated with the deilneation means to create a rumble strip, portion or area to alert a user of the fact that they have strayed onto the delineation means.

PreferaHy the rumble strip, portion or area is provided on or associated with at least a front wall of the delineation means.

In one embodiment one or more recesses and/or rumble strips, portions or areas extend from a top edge, attachment means and/or an opening of a channel in the front wall of the delineation means towards the base of the delineation means.

In one embodiment a recess, hollow or cavity is defined in the base of the delineation means. The recess, hollow or cavity is formed such that it allows the delineation means to be used on an uneven surface in use. For example, the recess, hollow or cavity can be formed such that the edges of the base defining the same have a degree of flexibility and can move outwardly as the device is being secured to a ground surface in use.

Preferably the hollow, cavity or recess is substantially hemispherical in shape or in the shape of a clam shell, with the opening of the clam shell or hemisphere facing the ground surface in use.

In one embodiment the delineation means is approximately 300mm wide or deep and approximately 125mm in height.

However the dimensions can be any suitable dimensions to perform the function of separating one or more road or path users from one or more other road or path users.

In one embodiment the front base edge (i.e. the edge between the front wafl and the base) is curved, outwardly curved, convex or substantiaUy curved in shape. For example, when the delineation device is viewed in plan from above, the front/base edge is convex in shape. this provides the device with a substantially hemispherical appearance.

In one embodiment the front base edge between the front wall and the base is linear, substantially linear or straight. In this example, when the delineation device is viewed in plan from above, the device has a substantially rectangular or square shape.

In one embodiment the delineation device is symmetrical or substantially symmetrical, such as for example, about a longitudinal axis of the device, about a transverse axis of the device and/or the like.

In one embodiment the delineation device is asymmetrical or substantially asymmetrical, such as for example, about a longitudinal axis of the device, about a transverse axis of the device and/or the like.

In one embodiment the delineation device is flat, planar and/or substantially flat and planar along a top surface thereof.

According to a second aspect of the present invention there is provided a method of using delineation means. The method could include the steps of placing a base of the device on a road or pathway that is to be divided into sections in use.

Preferably the longitudinal axis of the device is arranged substantiafly paraflel to a ongitudina axis of kngth of the road or pathway which is to be divided into sections in use.

Tn one embodiment the delineation means is a cyck delineation means or device for delineating a cycle way from a pedestrian area, a vehicle lane and/ or the like in use.

The term delineation means refers to any device that can act as a delineating or separation means for separating one or more vehicles, objects, users, transportation means and/or the like from one or more other vehicles, objects, users, transportation means and/or the like.

The delineation means can be quickly and easily fitted and/or removed, is inexpensive to produce and fit. No excavation of an existing road surface needs to be made in order to fit the device in use. Furthermore, the device can be removed from an existing road surface where it has been used without requiring repair of the road surface.

An embodiment of the present invention will now be described with reference to the accompanying figures, wherein: Figures ia-id show a front perspective view, a rear perspective view, a front view and a top view of a delineation device according to one embodiment respectively; Figure 2 is a cross sectional view taken through the delineation device in figures la-id; Figure 3 is a front perspective view of the delineation device with car tvres to show how the device works; Figure 4 illustrates the angle difference of the rear wall relative to the height of the delineation device; Figres 5a-5e show an end view, a front view, a top plan view, a front perspective view and a rear perspective view of a deilneation device according to one embodiment of the present invention respectivdy; Figure 6 shows three examples of delineation devices according to further embodiments of the present invention; and Figures 7a-7d show a perspective view, a front view, a top plan view and an end view respectively of a delineation device according to a yet further embodiment of the present invention.

Referring to figures 1-4, there is illustrated a delineation device 2 according to an embodiment of the present invention. Ihe delineation device in this example is used on a roadway to separate a cycle lane from a vehicle lane to provide improved safety for cyclists travelling on the cycle lane. The delineation device is designed to prevent motorists from straying from the vehicle lane into the cycle lane and to reduce the likelihood of a cyclist impacting the delineation device and falling off Ihe delineation device 2 has a front wall 4, a rear wall 6, a top edge or surface 8, base 10 and end walls 12. In accordance with the present invention, the front wall 4 has a concave section 14 adjacent the lowermost front edge 16. In addition, a convex portion 18 is provided on front wall 4 adjacent top edge 8. Ihe front wall 4 is shaped so as to provide a smooth transition between the convex portion 18 and the concave portion 14.

Rear wall 6 is provided substantially perpendicular to the base 10 or is provided at a small acute angle to the vertical so as to define a steep slope or step portion. Ihe gradient of the rear wall 6 can change between the base 10 and the top edge 8 and, in the illustrated example, a section 22 adjacent lowermost rear edge 20 is perpendicular or substantially perpendicular with respect to base 10. A section 24 between lowermost rear edge 20 and top edge 8 is provided at a small acute angle to the vertical so as to provide a steep angled s'ope.

Attachment means in the form of a plurality of channds are defined between front wall 4 and base 10 with openings 26 of each channd defined in base 10 (not shown) and front wall 4. In use, bolts or other suitable attachment means are placed through the channels to allow the device 2 to be bolted to the road surface in use in a required position. A cover or cap can be provided for ocation over the openings 26 of the channds so as to prevent water, debris, rubbish and/or the like from entering the channels.

Rumble strips or lines 28 ate provided on front wall 4 and extend from channel openings 26 downwardly to lowermost edge 16. In the illustrated example, a pair of rumble lines diverge outwardly and downwardly from each other from each channel opening 26 so as to provide spaced apart nimble lines 28 on the front wall. The section of the front wall 30 between each rumble line pair 28 is typically recessed with respect to the surrounding front wall section 14 so as to allow a cyclist riding over front wall section 14 to feel a clear demarcation or sensation as their bike wheel travels between the raised front wall section 14 and the recessed front wall section 30.

However, the degree of recess is such so that the wall 32 between the recessed front wall section 30 and the surrounding front wall section 14 does not form a step sufficient to result in damage to a bike wheel or cause a cyclist to fall off their bike. It is to be noted that the recessed front wall section 30 is also concave in shape. Ihe angle of curvature can be the same or different to that of the surrounding front wall section 14.

Although the rumble strips are provided in the concave section 14 of the front wall 4 in the illustrated example, it will be appreciated that the rumble strips could extend into the convex section 18 of the front wall 4 if required. in

In the illustrated example, the openings 26 of the channels are provided in the convex section 18 adjacent the boundary between the convex section 18 and the concave section 14. However, it will be appreciated that the channel openings could be provided at any suitable location.

The dehneation device 2 can be formed from a sohd singk motild piece of material, such as for example, recycled rubber. The rubber material has a degree or resilience so as to aflow the device to be used on uneven ground.

A recess 34 can be defined in base 10 so as to increase the degree of flex of the base 10 when being attached to a road surface in use. The edges of the base defining recess 34 can move outwardly of each other to allow the base to be moved closer into contact \vith the road surface when fitted. In the iflustrated examp'e, the recess is substantially hemispherical in shape or clam shaped.

In use, a plurality of the delineation devices 2 are typically arranged in a line with an end 12 of one device adjacent to and substantially opposite an end 12 of an adjacent device 2. The devices 2 can be provided a spaced distance apart, as shown in figure 3, or the devices 2 can be provided in an end to end abutting relationship to provide an elongate curb like structure. The rear wall 6 of each device 2 is arranged so as to face the vehicle lane of the roadway. The steep slope defined by rear wall 6 provides a pronounced step such that a car or lorry wheel 36 is prevented from, or at least cannot easily, mount the device 2 and pass onto the front wall 4 of the device. 1he front vall 4 of each device 2 is arranged so as to face the cycle lane defined in the roadway. 1he gentle concave curvature of the lower section 14 of front wall 4 allows a cyclist to mount the lower section with their bike without causing the cyclist to fall off their bike. The gradient of the slope of the front wall 4 becomes steeper as it moves from the lower concave section 14 to the upper convex section 18, thereby preventing or making it difficult for a cyclist to travel higher up the front wall 4 towards top edge 8 and accidentally pass into the vehicle lane adjacent rear wall 6. The rumble strips defined between lines 28 on the front wall inform a cyclist as they travel over the same that they have accidentally moved onto the delineation device and that they need to move back into the cycle lane.

Ihe lowermost front edge 16 of front wall 4 is almost flush or is of such a depthwith the ground surface such that no significant step is formed between edge 16 and the roadway that may result in a cyclist falling off their bike if they impact the same.

End pieces could be provided adjacent ends 12 which have a similar s'ope to front wall 4 so that cyclists do not impact the end walls 12 and fall off their bikes.

Figure 4 illustrates two delineation devices; device A which is 125mm in height and device B which is 150mm in height.

Ihus, it will be appreciated that the delineation device of the present invention provides an improved safer means for separating a cycle lane from a vehicle lane on a roadway which allows both a vehicle driver and a cyclist to be informed safely of the delineation between the lanes.

Figures Sa-Se illustrates a further embodiment of a delineation device 102. The same reference numerals have been used to describe the same features as described above. In this embodiment, rather than the front edge 16 being linear or straight, the front edge 16 has a convex curvature between opposite end walls 12. In addition, the edge between the ends 12 and the top surface 8 are curved. lhe curvature of the front edge and the end edges increases the safety of the device by reducing any step like raises at the ends of the device so as to prevent a step being formed on both the front and the ends that may cause a cyclist to fall off their bike if they impact the same.

A reflective material 104 is located on an between the top surface 8, rear surface 6 and front surface 4 to increase the visibility of the device to a user.

The device in figures 5a-5e is typicaUy symmetrica' when viewed in plan view and a line of symmetry to taken centrally of the device and perpendicular to the longitudinal axis of the device, as shown by line 106. The device is asymmetrical when viewed along the ongitudinal axis of the device.

Figure 6 show's a perspective view of three different designs of delineator devices that fall within the scope of the present application.

Figures 7a-7d illustrates a yet further embodiment of the present invention in which delineation device 202 has a relatively flat or planar top surface 8, the front and rear surfaces 4, 6 has concave in curvature and the ends 12 has convex in curvature. The device is symmetrical about both the longitudinal axis and a central axis take perpendicular to the longitudinal axis.
