One or a plurality of first (137 Figure 4) and second end walls are displaced from the first and second planes. The protrusions allow a range of column widths to be accommodated. The outer wall of the protector may comprise a convex wall portion and the protrusions may be spaced apart from each other. Also claimed is a protector comprising a curved wall portion and an end portion that occupies a plane parallel to the plane of a second inner wall portion. A system of protectors comprising outer parts forming a continuous non-circular cylindrical curve and first and second sets of projections capable of engagement, with the first set forming an angle in the range of 90º-180º with the second set, is also claimed.

Description

COLUMN PROTECTOR

Field of the Invention [0001] The present invention relates to protectors for structural members.

Background of the Invention [0002] The present disclosure relates to column protectors for protecting upright columns or posts, for example as found in sheds, commercial buildings, warehouses or the like. Typically in a commercial building such as a large shed, an industrial or commercial warehouse or the like there are columns or posts present, usually in the form of an “Η”, T, square shaped or round beam, girder or joist. Such upright or vertical posts or columns can be used to support roof structures, floor structures, platforms, mezzanine floors, or may comprise rack legs of warehouse rack systems.

[0003] A known problem encountered in commercial buildings where mechanical handling equipment (MHE) or vehicles are present is that there may occur collisions between the handling equipment or vehicles which may damage upright columns or posts which are holding up roof structures, platforms, mezzanine floors or racking systems. Particularly in the case of warehouse rack systems, upright legs if damaged can lead to collapse of the racking. Warehouse racking systems may contain several tons of items stored and the damage of a single upright leg along a length of racking may lead to collapse of the whole length of racking. Due to the close proximity between adjacent rows of racking, the collapse of one row of racking can lead to a domino effect which knocks over adjacent rows of racking. Collapses in racking systems can be highly dangerous and may crush warehouse personnel in the vicinity. In some cases, where the racking systems store flammable liquids there may be bursting of containers, spillage of liquids and subsequent fire or explosion.

[0004] Prior art column protectors having a substantially circular cylindrical outer shape are known in which a pair of such column protectors may be placed

-2around the base of a column to protect a lower length of the column nearest a floor. These column protectors typically have a dowel and plug type engagement between two such column protectors, in which a set of typically circular cylindrical plugs arranged horizontally on a first side of a first column protector engage a set of corresponding opposite circular cylindrical horizontally arranged holes or apertures on a second side of a second column protector. This known type of column protector therefore only accommodates a single aperture size between two such column protectors engage together, which means that a range of such column protectors must be produced to match a range of different width columns.

Detailed Description of the Embodiments [0044] There will now be described by way of example a specific mode contemplated by the inventors. In the following description numerous specific details are set forth in order to provide a thorough understanding. It will be apparent however, to one skilled in the art, that the present invention may be practiced without limitation to these specific details. In other instances, well known methods and structures have not been described in detail so as not to unnecessarily obscure the description.

[0045] In this specification, each technical feature of any embodiment may be incorporated in any other embodiment disclosed herein, unless the context specifically denotes otherwise.

[0046] In this specification the embodiments are referred to in a coordinate space comprising three spatial lines X,Y and Z. The three lines are orthogonal to each other, each line comprising two directions being 180° opposite to each other. In the general case the X and Y lines need not be horizontal and the Z line need not be vertical, but preferably where a direction of travel is referred to as being in an X or Y direction then such direction will lie in a horizontal plane. Similarly where a movement is referred to in a Z direction, such direction of movement will be in a substantially vertical plane.

[0047] In this specification, the terms column” and “post” are used interchangeably to mean the same thing. Normally, a column or post would be arranged upright, and typically be positioned substantially vertically. However the terms “column” or “post” as used herein are broad enough to encompass elongate members which are arranged with their main length direction at an angle to

-12vertical, for example 45° to vertical, for example in the case of a cross beam or crossmember, or at 90° to vertical, i.e. substantially horizontally, in the case of a barrier. Where a protector is referred to as a “column protector” it will be understood by the skilled person that the protector could equally be used for protecting a post, beam, barrier corner piece or other component, whether structural or not, which may be subject to accidental damage from collision from vehicles, mechanical handling equipment or the like.

[0048] Referring to Figures 1 to 7 herein there is shown schematically in perspective view from above and one side a pair of individual column protector devices 100 each according to a first specific embodiment.

[0049] Each column protector comprises an elongate central body portion 102; a first side 103; a second side 104; a front wall section 105 extending between said first and second sides; a rear wall section 106 extending between said first and second sides and being spaced apart from said front section; a first end 107 and a second end 108, said first and second ends being opposite each other and each being located between said first and second sides, and between said front and rear wall sections.

[0050] The front wall section 105 comprises a substantially part cylindrical convex outer surface 109 which extends across said body between the first and second sides. The rear wall section comprises a substantially overall concave inner wall surface 110 which extends across said body between said first and second sides. The first side 103 has a first set of finger like projections or protrusions 111 - 114. The second side 104 has a second set of finger - like projections or protrusions 115-118.

[0051] The first set of finger - like projections or protrusions 111 - 114 extend from the body 102 in a first direction, and the second set of finger - like protrusions 115-118 extend from the body 102 in a second direction, the first and second directions being substantially orthogonal to each other.

-13[0052] The inner surface 110 comprises first and second inner faces 119, 120 which lie respectively along first and second planes, arranged substantially orthogonally to each other, said first inner face 119 extending along said first set of finger - like protrusions, and said second inner face 120 extending along said second set of finger-like protrusions. The outer surface 109 comprises a substantially a non-circular part cylindrical portion extending around said body, around said first set of protrusions 111 - 114 and around said second set of protrusions 115-118.

[0053] On the first side, the first finger - like protrusions are interleaved with a first set of gaps 121 - 124 which separate adjacent ones of the first finger like protrusions. On the second side there are provided a second set of gaps 125

- 128 which are interleveed between the second set of finger- like protrusions and which separate adjacent ones of the second set of finger - like protrusions.

[0054] In use, a plurality of said column protectors may be used to surround a post, column, beam or barrier in order to protect the post, column, beam or barrier from impact from passing vehicles, mechanical handling equipment or the like. A pair of said column protectors may be arranged surrounding a substantially square or upright column or post so as to substantially fully surround said column or post. In use, the first set of finger like protrusions 111

- 118 of a first column protector engage in a second set of gaps 125 - 128 between a second set of finger-like protrusions 115 - 118 of a second column protector, and a second set of finger-like protrusions 115 - 118 of said first column protector 100 engage in use in a set of first gaps 121 - 124 between individual protrusions of a first set of finger-like protrusions 111 - 114 of the second column protector such that the first and second column protectors engage each other to form a central passage there-through which substantially encloses around said column or post.

[0055] Referring to figure 2 herein, there is illustrated schematically first and second column protectors of the first embodiment engage together in a maximum compacted configuration in which the combined column protectors occupy a minimum external volume. In the maximum compacting configuration,

-14the first protrusions 111 - 114 of a first column protector substantially fully occupy the voids or gaps between and/adjacent the second protrusions 115 - 118 of said second column protector, and similarly, the second protrusions 115-118 of said first column protector substantially fully occupy the gaps or voids between the first protrusions 111 - 114 of the second column protector.

[0056] As in the maximum expanded engaged condition as shown in figure 1 herein, in the maximum compacting engaged condition, the two column protectors can be secured together by passing a band or strap around the two channelled recesses which are formed into the outer surfaces of the column protectors.

[0057] Referring to Figure 3 herein, there is illustrated schematically two identical column protectors which are fully disengaged from each other, that is, which are separated from each other having no touching contact between them, and no overlap of fingers between them.

[0058] Referring to Figure 4 herein, there is shown in view from one end, a single column protector. The view corresponds to a view from underneath of the column protector 100 shown on the right hand side of Figures 1,2 or 3 herein, or equivalently a view from above the column protector shown on the left-hand side of Figures 1,2 or 3 herein.

[0059] In the embodiment shown, the outer suface 109 as viewed from one end in a direction along a main length axis of the column protector comprises a substantially part - cylindrical central section 400 extending over an arc of around 80°, which follows a sine, cosine, elliptical or arched curve; at the first side there is a first portion 401 of the outer surface 109 which is substantially planar having its plane in a direction parallel ot the main length direction of the column protector. Each protrusion of the first set of protrusions comprises a part of the substantially planar surface 401. Between the curved central portion 400 and the first substantially planar surface 401 each protrusion of the first set has a second curved part - cylindrical surface 402 having a smaller radius of curvature than the approximate radius of curvature of the curved central section 400. On an opposite

-15side of the first substantially planar surfaces 401 to the first part-cylindrical curved surfaces 402, each first protrusion has a third part-cylindrical curved portion 403. The third part cylindrical curved surfaces 403 are adjacent to a fourth part cylindrical curved surface 404.

Between the curved portion 400 and the second substantially planar surfaces 405, each second protrusion has a fifth curved part - cylindrical surface 406 having a smaller radius of curvature than the approximate radius of curvature of the curved central section 400. On an opposite side of the second substantially planar surfaces 405 to the fifth part-cylindrical curved surfaces 406, each second protrusion has a sixth part-cylindrical curved portion 407. Adjacent each sixth curved portion 407 is a seventh part cylindrical curved portion 408.

[0061] The rear or inner surface 110 of the column protector comprises the first and second inner faces 119,120 which are arranged substantially orthogonal to each other and which meet each other at a position midway between the first and second substantially planar surfaces 401, 405. The first inner face 119 extends along the first finger - like protrusions on the opposite side of those protrusions to the first substantially planar surfaces 401, the second part cylindrical curved surfaces 402, and the third part cylindrical curved surfaces 403.

[0062] The second inner face 120 extends along each of the second finger like protrusions on the rear of the column protector, on the opposite sides of the second finger like protrusions to the second substantially planar surfaces 405, the fifth part cylindrical curved surfaces 406, and the sixth part cylindrical curved surfaces 407, and is joined to the sixth part cylindrical curved surfaces by the seventh part cylindrical curved surfaces 408.

[0063] Between the first substantially planar face 119 and the first substantially planar outer surface 401, each first protrusion comprises a fourth part - cylindrical curved portion 404 having as it smallest radius, a radius of curvature

-16which is smaller than the radius of curvature of the second curved part - cylindrical surface 402.

[0086] A fifth segment arranged adjacent the second section in the main length direction along the first column protector comprises a portion of the main body 102, a portion of the second inner surface 120; a portion of the first inner wall

-20surface 119; a portion of the outer surface 109; a second end wall 138; and a single second fingerlike projection or protrusion 104.

[0087] A sixth segment 114 arranged adjacent the second section in the main length direction along the first column protector comprises a portion of the main body 102, a portion of the second inner wall surface 120; a portion of the first inner wall surface 119; a portion of the outer surface 109; a first end wall 137; and a single first fingerlike projection or protrusion 112.

[0088] A seventh segment arranged adjacent the second section in the main length direction along the first column protector comprises a portion of the main body 102, a portion of the second inner surface 120; a portion of the first inner surface 119; a portion of the outer surface 109; a second end wall 138; and a single second fingerlike projection or protrusion 104.

Modes of engagement - two column protectors [0090] In Figures, 2 and 8 herein, there is illustrated schematically two identical first embodiment column protectors which are in full engagement with each other, in which they are engaged with each other to a maximum extent. In this condition, the two column protectors are at their most compact, and would both fit into a rectangular box space of smallest volume.

[0091] When to first embodiment column protectors are in full engagement, a second inner surface 120 of one column protector abuts an upper end face 137 of the other column protector, and a lower second inner surface 120 of the other column protector abuts the upper end face 137 of the one column protector as shown in Figure 8 herein.

-21[0092] In end view as shown in Figure 8 herein, the combination of two column protectors provides an overall outer shape of a truncated ellipse, being a substantially elliptical shape having its ends of minimum radius of curvature truncated by a substantially straight line corresponding to the first and second substantially planar services 401,405 as hereinbefore described.

[0093] In the maximum compacted configuration shown in Figure 8 herein, in the main length axis direction, the overlap between the second fingers of one column protector, and the first fingers of the other column protector is maximised, and the overlap between the first fingers of the other column protector and the second fingers of the one column protector is also maximised. In the maximum compact configuration, the dimensions of a central channel 800 are at their minimum dimensions.

[0094] As shown in Figure 8 herein, when two first embodiment column protectors are engaged in a maximum compacted condition, the first finger projections of a first column protector substantially fully occupy the voids or gaps between the second fingers of the second column protector, and the first fingers of the second column protector substantially fully occupy the voids or gaps between the second fingers of the first column protector. Similarly, the second fingers of the second column protector substantially fully occupy the voids or gaps between the first fingers of the first column protector, and the second fingers of the first column protector substantially fully occupy the voids or gaps between the first fingers of the second column protector.

[0095] The minimum dimension of the central channel 800 formed between a pair of the first embodiment column protectors is determined by the distance between the plane of the first end walls 137 and the plane of the second inner wall 120 of the same column protector, and by the distance between the plane of the second end walls 138 and the plane of the first inner wall 119 of that column protector. The distance between the plane of the first first end walls 137 and the plane of the second inner wall 120 determines the minimum extent to which two column protectors can be compacted in a first direction, and the distance between

-22the plane of the second set of end walls 138 and the first inner wall 119 determines the distance by which to column protectors can be compacted together in a second direction, orthogonal to the first direction.

[0096] Referring to Figures 1 and 9 herein, there is illustrated schematically in view from one end along a main length axis of each column protector, a pair of first embodiment column protectors which are arranged parallel to each other in a substantially minimum engagement configuration in which a central channel 800 between the two column protectors is substantially at a maximum dimension.

[0097] In the minimum engaged configuration, there is minimum overlap of area in a direction axially along the main length direction of the column protectors between the second fingerlike protrusions of one first embodiment column protector, and the first fingerlike protrusions of the other first embodiment column protector, and a minimum area overlap in the axial direction between the second finger-like protrusions of the other first embodiment column protector, and the second finger-like protrusions of the one first embodiment column protector.

[0098] Between the maximum and minimum compacted configurations as shown in Figures 8 and 9 herein, there are a continuously variable range of intermediate positions in which the first embodiment column protectors may be moved closer or further away from each other to accommodate a continuously variable range of channel dimensions 800 between the two first embodiment column protectors. To vary the channel dimension between the two first embodiment column protectors requires sliding the column protectors towards or away from each other in a direction parallel to the planes which are occupied by the first and second substantially planar regions 401, 405 of the column protectors. In other words, the column protectors are slid towards or away from each other in a direction parallel to the substantially flat outer facing sides 401, 405 of the combined pair of column protectors.

[0099] In Figures 1 and 9 herein, two identical column protectors are in partial engagement with each other, allowing a maximum channel therebetween, whilst the two column protectors are still engaged with each other around a central

-23column or post. In a system comprising two column protectors, the central channel in plan view is a square shape having continuously variable side dimensions between a maximum and minimum side width.

Modes of engagement - four column protectors [0100] In an alternative deployment, a set of four first embodiment column protectors as disclosed herein may be used to surround a single post, column or beam. In such a deployment, a central substantially square or rectangular shaped elongate aperture or channel formed between four column protectors may have larger width and depth dimensions, as each side of a square or rectangular aperture is defined by two column protector devices, rather than by a single column protector device as is the case where only two column protectors are used to surround said post, column or beam.

[0101] Referring to Figure 10 herein, there is shown a deployment comprising four protector devices 1000 - 1003 arranged around a central post, column or beam at a same upright length position along said post, column or beam, which are in full engagement with each other, in which they are engaged to a maximum extent.

[0102] A first set of protrusions 111 - 114 of a first column protector 1000 engage with a second set of protrusions 115 - 118 of a second column protector 1001; a first set of protrusions 111 -114 of said second column protector engage with a second set of protrusions 118 of a third column protector 1002; a first set of protrusions 111 - 114 of said third column protector engage with a second set of protrusions 115 - 118 of a fourth column protector 1003; and a first set of protrusions 111 -114 of said fourth column protector engage with a second set of protrusions 115 - 118 of said first column protector, in order to form a combined protection extending all the way around the post, column or beam.

[0103] In a maximum compacted configuration of four first embodiment column protectors as shown in Figure 10 herein, the seventh substantially cylindrical curved surface 408 of each second fingerlike protrusion contacts the

-24end faces 137 in the gaps or voids on the first side of the column protector, and similarly, the fourth substantially cylindrical curved surfaces 404 at the end of the first fingerlike protrusions abut against the upright end walls 138 between the second finger - like protrusions.

[0104] Referring to Figure 11 herein, there is illustrated schematically four identical column protectors which are in partial engagement with each other, allowing a substantially maximum channel space therebetween whilst the four column protectors are still engaged.

[0105] In the maximum expanded condition, first set of protrusions 111 114 of a first column protector 1000 engage with a second set of protrusions 115118 of a second column protector 1001; a first set of protrusions 111 -114 of said second column protector engage with a second set of protrusions 115 - 118 of a third column protector 1002; a first set of protrusions 111 - 114 of said third column protector engage with a second set of protrusions 115 - 118 of a fourth column protector 1003; and a first set of protrusions 111 - 114 of said fourth column protector engage with a second set of protrusions 115 - 118 of said first column protector, in order to form a combined protection extending all the way around the post, column or beam.

[0106] In a maximum expanded configuration of four first embodiment column protectors as shown in Figure 11 herein, the seventh substantially cylindrical curved surfaces 408 of each second finger - like protrusion is spaced apart from the end faces 137 in the gaps or voids on the first side of the column protector, and similarly, the fourth substantially cylindrical curved surfaces 404 at the end of the first fingerlike protrusions are spaced apart from the upright end walls 138 between the second finger - like protrusions.

[0107] In each of the above configurations, the channel which encloses the post, column, or beam comprises the rear inner faces 119, 120 which form a right angle as viewed in a direction along the main axis length of the column protector, and the remaining outer surfaces form a convex surface extending around the intersection of the right angle formed by the inner surfaces 119, 120.

-25[0108] The versatility of the column protectors to be able to enclose a channel using either a pair of column protectors, or four column protectors relies upon the features of the inner concave surface forming a substantially right angle, in combination with a convex outer surface which extends all the way round from the end of one substantially flat planar inner surface 119 to the other substantially flat planar inner surface 120, and the angled shape of the finger - like protrusions, which enables the flat sides401,405 of the finger like protrusions to present a face externally which is at an angle of 45° to the adjacent inner surfaces 119, 120 respectively.

[0109] The first finger-like protrusions of one column protector are capable of engaging with the second finger-like protrusions of another adjacent column protector at an angle of between 90° in the case of two column protectors surrounding a central channel, and 180° in the case of four column protectors surrounding a central channel.

[0110] A central channel 1020 formed between the four column protector devices has a variable dimension in both a first horizontal X direction and a second horizontal Y direction by varying the amount of overlap and inter engagement of the finger-like projections or protrusions of the four column protector devices.

[0111] To extend the width of the central channel 1020 in a first horizontal X direction, first and second column protectors 1000, 1001 are kept in close engagement such that the second set of projections of the second column protector are in maximum overlap with the first set of projections of the first column protector 1000, and the first set of protrusions of the third column protector 1002 are maintained in maximum overlap with the second set of protrusions 1009 of the fourth column protector 1003, whilst the first and second column protectors together are moved away from the third and fourth column protectors 1002, 1003 so that the overlap between the second protrusions of the third column protector 1002 and the overlap between the first protrusions 1010 of the fourth column protector 1003 and the second protrusions of the first column protector 1000 is

-26reduced between their maximum overlap extent and then minimum over extent. In this manner, the width of the central channel 1020 is continuously variable over a range of distances in the first X direction.

[0112] Similarly, to extend the depth of the central channel 1020 in a second horizontal Y direction, first and fourth column protectors 1000, 1003 are maintained in close configuration with maximum overlap of the second set of projections of the first column protector 1000 and the first set of protrusions of the fourth column protector 1003 having maximum overlap, similarly, the second and third column protectors 1001, 1002 are kept in close engagement with the first projections of the second column protector being in maximum overlap with the second projections of the third column protector 1002. By moving the first and fourth column protectors further away from the second and third column protectors 1001, 1002, the extent of overlap between the second set of fingerlike projections of the second column protector and the first set of protrusions of the first, column protector is varied between the maximum and minimum overlap; and similarly, the extent of overlap between the first set of protrusions of the third column protector 1002 and the second set of protrusions of the fourth, protector 1003 are also varied between the maximum and minimum extent of overlap with the result that the dimension of the central channel 1020 second Y direction can be vary between the maximum and minimum extent.

[0113] A set of four column protectors can therefore accommodate a range of posts, columns or beams having in plan view a maximum width in the X direction and the maximum depth in the Y direction as viewed in plan view, and the shape of the central channel between the column protectors can be square or rectangular.

Dimensions [0114] Three separate best modes have dimensions as follows. Dimensions given relate to two separate shells in combination arranged surrounding a post or upright column, as shown in plan view in Figure 8 herein.

-27Whether a particular best mode is appropriate for a particular column or post depends on the dimensions and location of the column or post.

Aperture width E2 (two column protectors fully engaged) [0115] In all embodiments, preferably the finger like protrusions are tapered slightly in the horizontal direction so that their distal ends are slightly thinner than their regions which are nearest the body. This assists the protectors engaging with each other, as the finger - like protrusions of one protector engage with the finger like protrusions fo an adjacent protector device.

[0116] Preferably the protrusions are tapered at and angle of around 1° to the direction orthogonal to the main length direction of the protector.

-30[0117] Referring to Figure 12 herein, there is illustrated schematically a pair of two second column protectors, each according to a second specific embodiment. Each second embodiment column protector comprises the same features as the other, the two column protectors being identical. The features of the second embodiment, protector are substantially the same as those of the first embodiment column protector except for the differences hereinafter described. The features of a single second embodiment column protector 1200 shall now be described.

[0118] Each column protector 1200 comprises a main central body 1201; a first side 1202; a second side 1203; an outer facing surface 1204; an inner facing surface 1205; a first end 1206; a second end 1207; a first set of projections 1208 1211 at the first side; a second set of projections 1214 - 1217 at the second side; a first set of gaps or voids 1218 - 1221 interspersed between the individual projections 1208 - 1211 of the first set of projections; and a second set of gaps or voids 1222 - 1225 interspersed between the individual ones of the second set of projections 1214-1217.

[0119] In the second column protector 1200 a projection 1217 of the second set 1214 -1217 which is nearest the first end 1206 extends slightly longer away from the central body than the remaining other second projections 12141216 of the second set. At the first side, a first projection 1208 of the first set of projections 1208 - 1211 which is nearest the second end 1207 extends outwardly a distance further than the extent of the remaining first projections 1209 - 1211 of the first set. Having two projections which are slightly longer than the other projections, one in the first set of projections and another in the second set of projections, allows for two of the column protectors to touch and support each other at their ends, by virtue of those longer projections touching the corresponding opposite faces of the opposite column protector, whilst the other remaining projections of the first and second sets of projections which are more central to the body engage in their corresponding voids or gaps in the opposite

-31column protector without the distal ends of the fingers touching their opposing surfaces on the opposite column protector.

[0120] Referring to Figure 13 herein, there is shown in a maximum compacted engagement, two of the second embodiment column protectors. The two second embodiment column protectors define a central channel therebetween into which a post or column may fit.

[0121] Two of the second column protectors may be fitted around a column or post and be able to accommodate a range of different post which, as shown in Figures 8 and 9 herein, in the same manner as the first embodiment column protector, and similarly as described herein before with respect to the first column protector.

[0122] The outer or front section comprises a substantially part cylindrical convex outer surface which extends across said body between the first and second sides. The rear section comprises a substantially overall concave inner surface which extends across said body between said first and second sides.

[0123] As shown in Figure 13 herein, when engaged in a maximum compacted condition, the first finger like projeections of one column protector occupy the voids or gaps between the second finger like projecitons of the other column protector, and the first finger like projections of the other column protector substantially occupy the voids or gaps between the second finger like projections of the one first column protector. Similarly, the second fingers of the second column protector substantially occupy the voids or gaps between the first fingers of the first column protector, and the second fingers of the first column protector occupy the voids or gaps between the first fingers of the second column protector.

[0124] However whereas the uppermost first finger-like projection, and the lowermost second fingerlike projection each substantially fully occupy the gaps or voids adjacent the finger-like projections of the opposite column protector, for the first and second fingerlike projections which are more central along the main axial

-32length of the column protector, these do not extend towards the end walls in the gaps or voids of the opposite column protector to as great an extent, and there is an air gap between the ends of the centrally located finger-like projections and the opposite sidewalls of the body of the other column protector.

[0125] Referring to Figures 14 to 20 herein there is shown a third column protector according to a third specific embodiment.

[0126] Referring to Figure 14 herein, there is illustrated schematically in perspective view from above and a rear, the third column protector 1400.

[0127] The third embodiment column protector comprises like-for-like features as the first embodiment column protector hereinbefore described, but with variations as described herein. The third embodiment column protector comprises an elongate central body portion 1401; a first side 1402; a second side 1403; a front section 1404 extending between said first and second sides; a rear section 1405 extending between said first and second sides and being spaced apart from said front section; a first end 1406 and a second end 1407, said first and second ends being opposite each other and each being located between said firs and secnd sides, and said front and rear sections.

[0128] The front section 1404 comprises a substantially part cylindrical convex outer surface 1408 which extends across said body between the first and second sides. The rear section 1405 comprises a substantially overall concave inner surface which extends across said body between said first and second sides. The concave inner surface of the rear section falls predominantly along two intersecting planes disposed at 90° to each other, a first said innner plane bounding section of the central body and a section of each first finger -like projection; and a second said inner plane bounding a second portion of said body and extending along and bounding each second finger -like protrusion.

[0129] On the first inner substantially planar surface, there are provided a first plurality of elongate slots or channels recessed into said inner substantially planar surface. Similarly, On the second inner substantially planar surface, there

-33are provided a plurality of elongate slots or channels 1409 - 1416 recessed into said otherwise substantially planar surface on the second inner face extending along the second finger-like protrusions.

[0130] On the first side 1402 there are provided a first set of finger - like protrusions or projections which are equidistantly spaced apart from each other in a direction along a main upright length axis between the first and second ends. In the third embodiment, on the first side there are four finger - like projections or protrusions which extend in a main direction along a first plane. All of the four first finger like projections are of the same shape as viewed in a direction from one end of the column protector.

[0131] On the second side 1403 there are provided a second set of fingerlike protrusions or projections which are equidistantly spaced apart from each other in an end direction along a main upright length axis of the third column protector, between the first and second ends. On the second side, there are four finger-like projections or protrusions which extend in a main direction along a second plane, the second plane being substantially orthogonal to the first plane with the overall effect that the first fingers extend in a direction outwardly away from the second fingers, with the first fingers pointing in a direction which is 90° to the direction in which the second fingers point. All of the second fingerlike projections have the same outer shape as each other as viewed in the main axial length direction.

[0132] On the first side, the first fingers or projections are arranged spaced apart from each other, each having a void or gap between itself and an adjacent first finger -like projection.

[0133] Similarly, on the second side, the second finger-like projections are arranged spaced apart from each other with a plurality of second gaps or voids, each first finger being adjacent to a void, so on each of its upper and lower surfaces, each first fingerlike projection has an adjacent void or gap. In the main length direction of the third embodiment column protector, the first fingers are alternated in position with the second fingers, so that in a same plane which is 90°

-34to the main length axis of the third column protector, a second finger on the second side lies on the same plane as a gap or void where there is an absence of a first finger on the first site. Similarly, in a plane bisecting a said first finger, said plane lying at 90° to the main axial length of the third column protector, on the second side of the column protector there is no second finger.

[0134] Referring to Figure 19 herein, there is illustrated schematically in view from one end the third embodiment protector device as shown in figures 14 to 18 herein. Each segment containing a second finger - like protrusion comprises on the rear of the protector, first inner substantially planar surface 1420; second inner substantially planar surface 1421; first curved outer surface 1401; first substantially planar outer surface 1422; second curved outer surface 1423; third curved outer surface 1424; fourth curved outer surface 1425, between said second inner substantially planar surface 1421 and first substantially planar outer surface 1422; and substantially planar end surface 1426 which extends between the first curved outer surface 1401 and the first substantially planar inner surface 1422.

[0135] Referring to Figure 20 herein, there is illustrated schematically in view from the other end, the third embodiment protector device as shown in figures 14 to 18 herein. Each segment containing a first finger-like protrusion is bounded by, on the rear of the protector, first inner substantially planar face 1420; second inner substantially planar face 1421; end wall 1426, which extends in a direction substantially parallel to said first substantially planar face 1420, and orthogonal to said second substantially planar inner face 1421; first convex curved outer surface 1401; fifth part cylindrical convex curved surface 1427; substantially planar outer face 1428; sixth part cylindrical convex curved outer surface 1429; and seventh part cylindrical convex outer curved surface 1430.

[0137] In use, a plurality of said third embodiment column protectors may be used to surround an upright post or column in order to protect the post or column from impact from passing vehicles, mechanical handling equipment or the like in the same manner as the first embodiment column protector as hereinbefore described.

[0138] Each column protector comprises main body having extending therefrom a first set of finger - like projections or protrusions on a first side of said body; a second set of finger - like protrusions on a second side of said body; an inner surface lying substantially along first and second planes arranged substantially orthogonal to each other, said first plane extending along said first set of fingerlike protrusions, and said second plane extending along said second set of finger-like protrusions; and an outer surface comprising substantially a noncircular part cylindrical portion extending around said body, around said first set of protrusions and around said second set of protrusions.
