Description
RAILWAY PLATFORM SAFETY GUARD ASSEMBLY
This invention relates to various aspects of a safety guard for providing protection at the edge of a railway platform. In particular, this invention relates to a safety guard assembly for connection to the edge of a railway platform in the form of a plurality of safety guard members, and also to an individual safety guard member for use in such an assembly.
The necessity to carry out maintenance or repair work on a railway platform presents various safety issues. It is important to ensure that such work can be carried out without risk of injury to personnel (workers or passers-by). Such issues include the need to ensure accidental access past the platform edge is restricted, to prevent falls, to make sure that contact between passing trains, road rail plant and personnel is not easily possible and to minimise as far as possible any risk of electrocution as a result of falling overhead lines due to the safety guard assembly being constructed from a non-conductive material.
At present such work is usually carried out during the night with the railway declared out of use, in order to cause the least disruption to train passengers, and the minimal amount of financial loss to the train operators. Various types of constructional safety barrier exist but these are not suitable for use on a railway platform edge.
For obvious safety purposes, metallic structures on railway platforms (e.g. waiting shelters, lighting columns etc.) must be electrically bonded in order to reduce the risk of an electric shock, should one of the railway overhead lines snap (touch potential). Many existing safety barriers are formed from metal, thus, if
-2used on a railway platform, would also require an electrical bond to control the risk of electrocution. The need for such bonding increases assembly complexity, time and cost. Safety barriers formed from plastics material are available but these are generally free-standing and non-rigid so need to be weighed down with sandbags or otherwise secured to reduce the risk of movement due to the wind or due to a personnel fall. As a result, regulations stipulate that such barriers are not allowed nearer than 1.5m - 2.5m from the platform edge, depending on line speed and height of barriers, which reduces the working space and can serve as a trip hazard.
Safety barriers which are designed temporarily to connect to the edge of a platform on a construction site also exist, but these are generally time consuming to install, requiring various holes to be drilled to secure the barrier to the platform thus also damaging the asset it gets fixed to. Again, so as to have the required strength properties, such barriers also tend to be formed from metal and have to be electrically bonded. Additionally, the connection of these barriers with the platform edge of a railway, as opposed to another type of construction site, would cause contact with passing trains or other road rail vehicles so this type of safety barrier is not suitable for such use.
It is a principle aim of the present invention to provide apparatus which can be releasably connected to a platform edge with speed and relative ease and which addresses at least some of the issues discussed above.
According to a first aspect of this invention, there is provided a railway platform safety guard assembly comprising a plurality of safety guard members, each member independently configured for connection to the edge of a railway
-3platform in a spaced relationship relative to other members, and one or more barrier elements configured to connect to members so as to extend therebetween, each member comprising an elongate bar arranged to extend upwardly from the platform surface adjacent an edge and having support means for the connection of the one or more barrier elements; and a releasable fixing mechanism secured to the elongate bar and arranged to clamp around the edge of the platform.
The safety guard members can be individually connected to a platform edge and then once they are installed the barrier elements can be secured thereto. This ensures that the installation of the safety guard assembly can be carried out in a methodical and non-cumbersome manner. Additionally, as discussed in more detail below, the releasable clamping mechanism requires no drilling of holes or other constructional action in order to connect to the edge of the platform. This not only saves time but also greatly simplifies the installation process and also the making-good processes.
The one or more barrier elements preferably serve to restrict access past the railway edge and any form of barrier that serves this purpose would be suitable. The barrier element may comprise one or more panels or bars arranged to form a fence type barrier. In a preferred arrangement, the barrier element comprises one or more rails arranged to extend horizontally between safety guard members. The one or more rails may be sized to extend between two or more than two safety guard members. The spaced relationship between adjacent safety guard members is variable and may depend on the size of the platform to be worked and or the size of the or each barrier element.
-4The support means preferably includes some form of fixing or fixings to enable one, or more than one, barrier element to be supported thereby. The support means may comprise at least one bracket. The bracket may comprise one or more channel configured to support a rail extending between safety guard members.
The assembly of this aspect of the invention must comprise at least two safety guard members to support a barrier element and thus serve the function of providing an access barrier.
According to a second, but closely related aspect of the invention there is also provided a railway platform safety guard member for connection to the edge of a railway platform, the member comprising an elongate bar arranged to extend upwardly from the platform surface adjacent an edge and having support means for the connection of one or more barrier elements to be supported thereby; and a releasable fixing mechanism secured to the elongate bar and arranged to clamp around the edge of the platform.
It will be appreciated that the railway platform safety guard member as discussed herein is the same as each safety guard member discussed as part of the safety guard assembly. As such, references to the safety guard member shall be construed as referring to both the independent member per se and as part of the overall assembly.
The term “adjacent” when used with respect to the position relative to the platform edge should be interpreted as meaning any position of the elongate bar which allows the releasable fixing mechanism to clamp around the edge of the platform. At a practical level the elongate member will need to be sufficiently
-5close to the edge to prevent undue or excessive obstruction on the platform surface but also not too close to the edge so as to cause obstruction to passing trains etc. Preferably the distance between the elongate bar and the platform edge will be less than 410mm
Preferably the safety guard member and or at least part of the member or assembly (where applicable) is formed from non-conductive material. The releasable fixing mechanism may be formed from metal, such as aluminium to ensure rigidity. When the safety guard member is part of a safety guard assembly, as discussed above, the entire assembly may be formed from non-conductive material. The material must have sufficient rigidity and strength to withstand the effects of stormy weather and also an accidental personnel fall. In a preferred arrangement, the material is pultruded Glass Reinforced Plastic (GRP).
The releasable fixing mechanism is preferably configured to enable the safety guard member to be clamped to the platform edge quickly and with relative ease. The fixing mechanism may provide an interference fit with the platform edge. Such an arrangement may require the mechanism to be specifically sized and/or formed from a resiliently flexible material to conform to the correct shape to ensure frictional engagement. More preferably, the fixing mechanism is arranged to be clamped by progressive tightening of the mechanism around a platform edge.
The fixing mechanism may comprise a base having a surface configured to engage the platform surface, adjacent the platform edge, and a retaining member connected to the base and arranged to move relative thereto so as to
-6secure a platform edge therebetween. This provides adaptability and enables the fixing mechanism to connect to a wide range of platforms of different sizes.
To provide increased stability to the safety guard member, the base is either formed from or includes a planar flange and the surface configured to engage the platform surface is provided on or extended by the planar flange. This will provide a larger surface area for forces acting on the base to be distributed. In this way, the risk of damage to the base, as a result of tightening of the fixing mechanism, is reduced.
An arm may be provided to connect the base to the retaining member. The arm may be integral to the base or may be fixed thereto during manufacture or assembly. Preferably, the arm is arranged to extend downwardly relative to the platform surface, remote from the elongate bar. In this arrangement, the arm ideally extends perpendicularly from the base. In this configuration, a return member may be arranged to extend from the arm, generally parallel to the platform surface, such that the base, at least part of the arm, and the return member together form a profile that is generally U-shaped in cross-section. The return member may be integral to the arm or may be fixed thereto during manufacture. Such a shape will normally correspond to the general shape of a platform edge and this should minimise any protrusion of the safety member beyond the platform edge. This configuration should avoid the possibility of contact between the safety guard member and a passing train or other road rail plant. The devices of the invention ideally do not extend very much beyond the platform so that passing trains or road rail plant are not obstructed and may continue to pass even during maintenance work. Advantageously, the retaining
-7 member may comprise a screw-threaded bar and the return member may have a correspondingly screw-threaded bore in which the bar is threadingly engaged. Preferably, the screw threads should be relatively coarse and ideally in the form of helical splines in order for relative rotation of the bar to cause quick axial displacement of the bar within the bore.
Preferably, the screw threaded bar includes an engagement plate at a first end thereof configured to engage the underside of the platform edge. The screw threaded bar may include a handle at or adjacent the second end thereof to facilitate rotational movement of the bar relative to the base. The co-operating screw threads provided on the retaining member and the bore of the return member are preferably configured so that the bar is moved axially relative to the bore on rotation of the handle, thus causing the engagement plate to move towards and engage the underside of the platform. In this way, the platform edge may selectively be clamped between the planar flange of the base and the engagement plate of the bar.
Relative movement of the bar allows for fine adjustment of the clamping connection of the mechanism around the platform edge. In a preferred enhanced configuration, it would be advantageous also to provide course adjustment of the connection in order to facilitate quick release of the safety guard member from the platform edge. To achieve this, the return member is preferably arranged to connect to the arm and to be movable linearly relative thereto. The arm and the return member may include cooperating releasable fixing means selectively to secure their relative positions. The releasable fixing means comprises a pin provided by the return member and a corresponding opening defined in the arm
-8in which the pin is engaged to retain the position of the return member relative to the arm. The pin may be carried by the return member, for example by a chain. Preferably, a series of openings are defined along the length of the arm for selective engagement of the pin to retain the return member in position.
The elongate bar may comprise a first section, which, once installed, extends upwardly from the platform surface and a second section extending from the first section and arranged alongside and parallel to the platform surface. The first and second sections may be integrally formed or secured together. The intersect between the first and second section may be curved and/or may include a right-angled corner. The base and the second section of the elongate bar may be configured releasably to connect together during installation to make such installation simpler. The base and second section may include cooperating members which engage to provide a connection. Such a connection may be a telescopic engagement of one of the base and second section within the other of the base and second section. The base may comprise a hollow or solid bar and the second section of the elongate bar may be configured telescopically to engage within the hollow or solid bar.
Alternatively, the base may further comprise a connector for securing the elongate bar thereto. The connector may serve also as support means and may comprise at least one slot, configured to support a board panel extending between safety guard members adjacent the platform surface. In this arrangement, the connector preferably has a holefor telescopically receiving the end of the elongate bar, adjacent the platform surface.
-9According to a third aspect of this invention there is provided a railway platform safety guard assembly as hereinbefore described comprising two safety guard members as hereinbefore described, each member independently configured for connection to the edge of a railway platform in a spaced relationship relative to the other member, and one or more barrier elements configured to connect to both members so as to extend therebetween.
By way of example only, an embodiment of this invention will now be described in detail, reference being made to the accompanying drawings in which:Figure 1 is a perspective view of an assembled but uninstalled first embodiment of safety guard member of the present invention;
Figure 2 is a perspective view of the uninstalled first embodiment of safety guard member of the present invention shown partially separated;
Figure 3 is a perspective view of a second embodiment of safety guard member of the present invention;
Figure 4 is a perspective view of the second embodiment of safety guard member of Figure 3 installed on a platform edge;
Figure 5 is a detailed view of the retaining member of the safety guard member of Figure 3; and
Figure 6 is a perspective view of the underside of an assembled safety guard member of the present invention installed on a platform edge.
Figures 1 and 2 relate to a first embodiment of safety guard member whereas figures 3 to 5 relate to a second embodiment of safety member. These
-10two embodiments share some common features and so the same reference numbers will be used to represent such common parts.
Each of the figures show a part of a railway platform safety assembly, comprising a safety guard member 10, 40 which is configured for connection to the edge 11 of a railway platform 12. Each member 10, 40 includes a tubular elongate bar 13, 41 having a generally square cross-sectional profile.
As best seen in Figures 2 and 3, the safety guard members 10, 40 of both embodiments are formed in two inter-engageable parts in the form of the elongate bar 13, 41 and a releasable fixing mechanism 25, 42. The releasable fixing mechanism 25, 42 includes a base 15, 43 which is similar in shape and form to the elongate bar 13, 41.
A generally rectangular planar flange 16 is secured to the underside of the base 15, 43 of the fixing mechanism 14, 42 and this is arranged to contact the surface 17 of the platform when the safety guard member 10, 40 is installed. This facilitates the distribution of forces (especially lateral ones) across the planar flange 16 to ensure a strong, secure and robust connection.
The releasable fixing mechanism 14, 42 is arranged to clamp around the edge 11 of the platform 12. An arm 18, 44 is integrally formed with the base 15, 43 and this extends perpendicularly from the base 15, 43 in a downward orientation so as to abut the edge 11 of the platform 12, when installed. A return member 19, 45 extends from the arm 18, 44 at or towards the end remote from and parallel to the base 15, 43. The base 15, 43 and the arm 18, 44 with the return member 19, 45 together form a generally U-shaped configuration, which is
-11 designed to extend around the edge 11 of a platform 12. The return member 19, 45 includes a threaded bore 20, as will be discussed in more detail below.
The fixing mechanism 14, 42 includes a screw threaded bar 21 which is configured to cooperate with the corresponding threaded bore 20 in the return member 19, 45 so as to move axially relative to the bore 20. The screw threaded bar 21 is provided with an engagement plate 22 at one end and a handle 23 at the opposed end, remote from the base 15, 43. Engagement plate 22 has a planar face 24 arranged to engage the underside platform surface 17 adjacent the platform edge 11.
In the first embodiment shown in Figures 1 and 2, the elongate bar 13 includes a first section 25 which is arranged to extend upwardly from the surface 17 of a railway platform 12, when installed. The bar 13 adjacent the platform surface 17 is curved and includes an integrally formed second section 26 which is arranged to extend alongside the platform surface 17 adjacent the edge 11. In this arrangement, the base 15 of the fixing mechanism 14 is designed telescopically to engage with the second section 26 of the elongate bar 13 and so is hollow and is slightly larger to facilitate receipt of the second section 26 therein.
In the second embodiment of Figure 3 to 6, a connector 46 is configured to be placed against the platform surface 17 and is either fixed to or integrally formed with the base 43 of the fixing mechanism 42. The connector 46 has a generally triangular profile in cross section and defines an opening 47 at the uppermost end in which the lower end of the elongate bar 41 is mounted. The connector 46 also defines a slot on the outer periphery to engage a panel barrier
29. A series of openings 48 are defined through the length of the elongate bar 41, each configured to receive a rail barrier element.
The arm 44 of this second embodiment is generally cylindrical and includes a series of circular apertures 52 along the length. The return member 45 of this embodiment is generally rectangular in cross section and includes a channel 49 therethough in which the arm 44 is located. The return member 45 is configured to move along the arm 44. A chain 50 connects a pin 51 to the return member 45. The pin 51 is engagable in the circular apertures 52 of the arm 44 to hold the return member 45 in position relative to the arm 44, as best seen in Figure 5.
In both the first and second embodiments two pairs of brackets 31 are provided on the elongate bar 13, 41 part-way along and spaced from each other. Each pair of brackets 31 is defined by two circular channels 30 immediately adjacent each other and defining clips. As illustrated in Figure 3, in addition to the openings 48 defined through the length of the elongate bar 41 in the second embodiment, a barrier rail 28 may be supported in one or each channel 30. Thus, the second embodiment of safety guard member includes two different means for connection of a barrier rail. These may be used as alternatives or in combination. Such a barrier rail is arranged to be supported by at least two safety guard members 10, 40 in order to form a safety guard assembly 33 which prevents access to the platform edge 11.
The safety guard assembly 10, 40 is installed firstly by securing the releasable fixing mechanism 14, 42 around the edge 11 of the platform 12. This is achieved by ensuring that the planar flange 16 of the base 15, 43 engages the
-13platform surface 17 and that the arm 18, 44 extends adjacent the platform edge
11. Installation of the guard member of the second embodiment involves an additional step of aligning the return member 45 by sliding it along the arm 44 so that the pin 51 can then be inserted into the highest possible opening 52 in the arm 44. For the safety guard members 10, 40 of both embodiments, to clamp the fixing mechanism 14, 42 to the edge 11, the handle 23 of the screw threaded bar 21 is rotated to cause the bar 21 to move relative to the return member 19, 45 of the arm 18, 44 so that the engagement plate 22 engages the underside of the platform 27. The handle 23 is rotated until a secure clamping connection is provided.
For the first embodiment of safety guard member 10, the second section 26 of the elongate bar 13 is then inserted into the hollow base 15 to provide an installed safety guard member 10. For the second embodiment of safety guard member 40, the elongate bar 41 is inserted into the opening 47 provided in the top of the connector 46. When more than one safety member 10, 40 is installed, one or more barrier rails 28 may be clipped into the circular channels 30 of the brackets 31 provided on the elongate bar 13, 41 and/or may be guided through the openings 48 in the bar 41 to provide a safety guard assembly 22. A panel 29 may be located within the slot 32 on the side of the connector 46.
The safety guard member 10, 40 and assembly 33 of the present invention ensure that a barrier may be erected quickly and safely and enables work to be carried out without disruption to train travel or at inconvenient times. The provision of a non-conductive but structurally resilient material negates the need for additional electrical bonding, thus saving effort, time and money.
