Embodiments of this invention relate to brackets, cross-brace members, tools, and decking members for modular platform systems (e.g. as used on construction sites).
There have been significant recent developments in relation to the design of modular platform (or decking) systems. Such systems provide a surface on which users can safely walk and work during the construction of buildings, for example.
For example, WO2013/054143 teaches the provision of a modular platform system, wherein upright posts have slots arranged around each post which are each configured to receive a downwardly projecting fin of a decking member. A decking member may, therefore, be supported by four such posts with a fin at each corner of the decking member received in a slot on a respective post.
Such modular platform systems allow for quick, simple, and safe platforms to be readily build and re-configured. The modular form of the systems allows many different platform configurations to be built with only a small number of different parts.
As described in WO2013/054143 cross-braces may be provided between the upright posts to improve the rigidity of the resulting platform. Providing cross-braces which attach securely to the upright posts can, however, be problematic. Similarly, a cross-brace is another part of the system which serves only one function (i.e. a cross-bracing function).
There is also a desire to provide more versatile and secure mechanisms for allowing slots (or members defining the slots) to be provided at multiple different locations along a length of an upright post.
Embodiments seek to alleviate one or more problems associated with the prior art.

Embodiments are described, by way of example only, with reference to the accompanying drawings, in which:
Embodiments may include a modular platform system 1 (see
The modular platform system 1 could take a number of different forms and some of these forms are described briefly herein, by way of example. The module platform system 1 could equally be a system generally as described in WO2013/054143 in some embodiments.
The modular platform system 1 may include one or more decking members 11. The or each decking member 11 may be formed from a rectangular or square frame 111 (see
The decking surface member 112 may be in the form of a grid structure, for example, and the decking surface member 112 may extend over a central space framed by the frame 111. In some embodiments, one or more peripheral edges of the decking surface member 112 are supported by the frame 111 and may be secured thereto (e.g. welded, soldered, clipped, adhered, bolted, or riveted). In some embodiments, the decking surface member 112 may be formed from multiple parts which collectively form the decking surface member 112 (the parts may or may not be interconnected to each other).
In some embodiments, one or more beams 113 (see
Accordingly, the or each decking member 11 may be a modular decking member 11 which may be provided as a single element of the modular platform system 1. The parts of the or each decking member 11 may be secured to each other to allow the decking member 11 to be used as a single item.
In some embodiments, the frame 111 includes a plurality of frame members 111a which may frame a space (i.e. may circumscribe a space) as described herein. In some embodiments, there are four frame members 111a arranged in two opposing pairs (with a longitudinal axis of each frame member 111a of one pair being substantially perpendicular to a longitudinal axis of each frame member 111a of another pair).
In some embodiments, the or each frame member 111a may define a recess 111b (see
The or each recess 111b may be configured to receive at least part of a beam 113 (see
In some embodiments, the or each recess 111b includes a lip 111c and this lip 111c may be located at an entrance of the recess 111b (which inwardly faces the framed space in some embodiments). The lip 111c may, therefore, at least partially define an entrance of the recess 111b.
The or each recess 111b may extend along substantially an entire length of the frame member 111a and may be open at one or both ends of the frame member 111a. The lip 111c may be a longitudinal lip 111c and may extend along substantially an entire length of the recess 111b and so, in some embodiments, of the frame member 111a. In normal use (i.e. in the usual operational orientation of the decking member 11) the lip 111c may project upwardly.
The or each beam 113 may include a hook portion 113a (see
The head of the hook portion 113a may be sized and/or shaped such that it cannot pass into the recess 111b of a frame member 111a past the lip 111c. As such, in some embodiments, the frame member 111a has at least one open end to the recess 111b and end (or ends) of the beam 113 (or beams 113) may be slid into the frame member 111a by aligning the opening of the hook portion 113a with the lip 113c at the open end of the recess and moving that end of the beam 113 along a length of the frame member 111a. Engagement of the hook portion 113a (e.g. of the opening thereof) and the lip 111c may prevent or substantially inhibit movement of the beam 113 out of frame member 111a (e.g. by movement of the beam 113 in a direction parallel with its longitudinal axis). The engagement may also keep the beam 113 generally perpendicular to the frame member 111a.
As mentioned, the same engagement configuration may be used at both ends of each beam 113 (in relation to respective ones of an opposing pair of frame members 111a) and multiple beams 113 may be attached to the same frame member(s) 111a in this manner. The position of the or each beam 113 along a length of the frame member(s) 111a may be secured by welding, soldering, adhering, clipping, or by bolting or riveting, for example).
The or each frame member 111a (or at least the frame member(s) 111a defining a recess 111b) may be formed from box section material.
With one or more beams 113 fitted to a first pair of opposing frame members 111a, for example, the frame 11 may be formed by securing a second pair of opposing frame members 111a to the first pair. In doing so, one or more open ends of the first pair may be at least partially covered or otherwise blocked (e.g. to inhibit removal of a beam 113 therefrom if such a beam 113 is not secured in position along the length of the relevant frame member(s) 111a).
In some embodiments, one or more diagonal beams 114 may be provided as part of the decking member 11. The or each diagonal beam 114 may extend between two respective diagonally opposing corners of the frame 111.
The or each diagonal beam 114 may be secured to the frame 111 (e.g. by welding, soldering, adhering, clipping, riveting, or bolting, for example). In some embodiments, the or each diagonal beam 114 is secured at its ends to respective end plates 115 (see
In some embodiments, the or each end plate 115 may provide the mechanism by which the frame members 111a are attached to each other (i.e. the attachment may be via one or more end plates 115). The or each end plate 115 may be a corner plate, therefore, and may be generally triangular in shape. The or each end plate 115 may be generally in the form of a right-angled triangular plate (although, as depicted, for example, the right-angled corner may have a cut-out, which may be a square cut-out). The or each end plate 115 may include two sides generally perpendicular with respect to each other and a diagonal side. The or each end plate 115 may be positioned such that a plane of the end plate 115 is generally parallel with the decking surface member 112. In some embodiments, the decking surface member 112 is provided on a first (upper) side of the decking member 11 and the end plate 115 is provided on a second (lower) side of the decking member 11. The two perpendicular sides of the or each end plate 115 may be attached to frame members 111a and the diagonal side may generally face (and extend across part of) the framed space. An end of one of the or each diagonal beams 114 may be attached to the diagonal side of the end plate 115.
There may be an end plate 115 provided at each corner of the decking member 11. The or each end plate 115 may be referred to, therefore, as a corner plate, for example (the terms are synonymous herein).
There may be two diagonal beams 114 in some embodiments and these may be joined in the middles thereof to form a cross, for example.
Therefore, in some embodiments, the diagonal beams 114 may be attached to the frame members 111a by the end plates 115 and the end plates 115 may be used to attach (or help to attach) the frame members 111a together.
The resulting structure has been found to be simple to manufacture and yet rigid and strong.
The corners of the decking member 11 may include cut-outs (e.g. between two ends of adjacent frame members 111a and/or in the end plates 115) and this may enable a closer fit, for example, with a support member 12 of the modular platform system 1.
The decking member 11 may include one or more fins 116 (or tine, or blade) and may include a fin 116 (i.e. at least one) at or towards each corner thereof.
The decking member 11 may, therefore, include at least four fins 116.
The or each fin 116 may extend generally perpendicular to a plane of the decking surface member 112 and may taper as it extends away from the decking surface member 112. The or each fin 116 may be located on an opposing side of the frame 111 to the decking surface member 112. The or each fin 116 may be attached to a respective one of the one or more end plates 115. In some embodiments, the or each fin 116 is integrally formed with a respective end plate 115. In some embodiments, the or each fin 116 extends from one of the two perpendicular sides of a respective end plate 115. In some embodiments, a plane of the fin 116 is generally parallel with a longitudinal axis of an adjacent frame member 111a. Therefore, it may be said that, in some embodiments, each frame member 111a is associated with at least one fin 116 and, in some embodiments, with a single fin 116. Around the perimeter of the decking member 11, there may be a single fin 116 at each corner of the decking member 11 and that fin 116 may be perpendicular to the two adjacent fins 116 around the decking member (and parallel to a fin 116 diagonally opposite). The or each fin 116 may equally be said to be associated with each end plate 115.
The or each fin 116 may extend generally perpendicular to a main plane of the end plate 115 with which it is associated, for example. In some embodiments, the fin 116 is integrally formed with its associated end plate 115 and may be a part which is bent into position. In other embodiments, the fin 116 may be welded, soldered, riveted, bolted, adhered, or otherwise secured to the end plate 115.
The integration of the fin 116 with the end plate 115 (rather than a frame member 111a), again, provides for simpler construction.
In some embodiments one or more (or all) corners of the decking member 11 (i.e. at the intersections of the frame members 111a) may be supported by a corner piece 117—see
Some embodiments may include a bracket 2 (see
The bracket 2 may, therefore, be configured to mate with the support member 12.
The support member 12 may be an elongate member (e.g. of square or rectangular box section) which is configured, in normal use in the modular platform system 1, to be upright (i.e. substantially vertical).
In some embodiments, the support member 12 may have a ground engaging end at which a foot plate is located. In some embodiments, the support member 12 may be configured to be fitted to another support member 12 (e.g. as an extension of the other support member 12, which may be in the form of a handrail support member, for example).
The support member 12 may be formed from box section material and may have a square or rectangular cross-section, for example. The support member 12 may be formed from a wall defining an internal space (i.e. may be tubular). The support member 12 may be elongate.
As mentioned, one end (a lower end in normal use) of the support member 12 may be configured to be secured to a foot plate (of the system 1) which may include a ground engaging plate 13 with a collar extending therefrom which is configured to receive or be received by the aforementioned end (i.e. a first end) of the support member 12.
The support member 12 (see
The first end configuration of the support member 12 may include a part 12a with a smaller external cross-section than another part (e.g. a main part) of the support member 12. The first end configuration 12a may be configured so as to be received within, for example, an internal space defined by the second end of another such support member 12—such that support members 12 may be coupled end-on-end (i.e. stacked). In some versions, a connection member 6 may be used for this purpose—see herein.
In some embodiments, the support member 12 may carry (i.e. support) one or more slot members 121, each of which is configured to receive a fin (which may be a fin 116 of a decking member 11 as described herein). In some embodiments, a plurality of such slot members 121 is provided around the support member 12 at substantially the same point along the length thereof. In some embodiments, one such slot member 121 is provided on each of a plurality of sides of the support member 12 (of which there may be four). The or each slot member 121 may be provided at or towards the second end of the support member 12.
The support member 12 may define one or more securing locations for the bracket 2. There may be a plurality of such securing locations provided along a length of the support member 12 and there may be one or more securing locations provided on more than one side (e.g. all sides) of the support member 12.
The or each securing location may include a plurality of apertures 122 defined through the wall of the support member 12. In some embodiments, each aperture 122 is defined through an entire thickness of the wall of the support member 12.
The apertures 122 may include one or more hook apertures 122a and may include one or more catch apertures 122b. The or each hook aperture 122a may be configured to receive a hook of the bracket 2 and the or each catch aperture 122b (if provided) is configured to receive a catch pin of the bracket 2 (if provided)—as described herein.
The securing locations are described in more detail with reference to the configuration of the bracket 2.
The bracket 2 may include one or more hooks (i.e. attachment hooks) 21 each of which is configured to engage the support member 12. The or each hook 21 is configured to be received by a hook aperture 122a of the support member 12. In some embodiments, more than one hook 21 of the same bracket 2 is received by the same hook aperture 122a of the support member 12. In this respect, we refer—for example—to
In some versions, there may be more than two hook apertures 122a provided (each of which is configured to receive both adjacent hooks 21 of a respective pair of adjacent hooks 21). The two or more hook apertures 122a may be provided on one (i.e. the same) side of the support member 12. The two or more hook apertures 122a may provide, therefore, an array of hook apertures 122a. In the depicted examples of
In instances in which a securing location has more than two hook apertures 122a, different ones of the hook apertures 122a may be used to secure the bracket 2 at different locations.
So, for example, there may be an upper or first hook aperture 122a and a middle or second hook aperture 122a and a lower or third hook aperture 122a. The lower or third hook aperture 122a may be configured to receive both hooks 21 of a first (e.g. lower) pair of adjacent hooks 21 of a bracket 2. The middle or second hook aperture 122a may be configured to receive both hooks 21 of a second (e.g. upper) pair of adjacent hooks 21 of the bracket 2.
Likewise, however, the bracket 2 may be secured such that the middle or second hook aperture 122a may be configured to receive both hooks 21 of the first (e.g. lower) pair of adjacent hooks 21 of the bracket 2. The top or first hook aperture 122a may be configured to receive both hooks 21 of the second (e.g. upper) pair of adjacent hooks 21 of the bracket 2.
Accordingly, the bracket 2 may be secured in a plurality of different locations along the length of the support member 12 in some versions and, in some versions, this may be achieved with using the same securing location (which may be one of several securing locations along the length of the support member 12).
This may be useful, for example, for fine-tuning of the height of a particular bracket 2. This may also be useful to enable the use of different configurations of decking member 11 and/or handrail 5. For example,
In some examples (see
The bracket 2 may define a slot 23 for receipt of, for example, a fin (which may be a fin 116 of a decking member 11 or may be a fin (of similar form) of a beam). The slot 23 may be defined by a plurality of walls of the bracket 2 and the bracket 2 may be formed from a sheet of material bent to provide the walls. The or each hook 21 may also be formed from the sheet of material. The sheet of material may be around 2 mm thick and may be a metal (such as steel).
The walls of the bracket 2 may, therefore, include two opposing side walls which may define a depth (i.e. height) of the bracket 2 and a width of the bracket 2. The two opposing side walls may provide the bracket 2 with a generally u-shaped cross-section and this can be seen, for example, in
The side walls may likewise define a depth of the slot and a width of the slot. The width of the slot may taper towards a first end of the bracket 2 (which is a lower end with the bracket 2 in its normal orientation in use, the second end being the upper end in the same orientation).
The first and second ends of the bracket 2 may be open ends (allowing access to the slot). The depth of the bracket 2 may be larger than the width of the bracket 2 (at its widest point). The depth of the bracket 2 may be larger than the thickness of the bracket 2.
The or each hook 21 may be provided at a rear of the bracket 2 and a further wall may be provided at a front of the bracket 2. The further wall may connect the two side walls and may define a thickness of the bracket 2 (i.e. a distance between the two side walls) and so a thickness of the slot 23. The further wall may, due to the tapering of the slot, be angled with respect to an opposing edge of the bracket 2. The further wall may be generally perpendicular to the side walls (e.g. see
The walls of the bracket 2 may form a u-shaped cross-section (with the slot being within the u-shape). Therefore, the rear of the slot may be open.
The or each hook 21 may extend rearward from the side walls and may be planar with the side walls.
The or each hook 21 may include a hook head 21a and a hook gap 21b (defined at least in part by the hook head 21a). In some embodiments, the hook gap 21b is defined between the hook head 21a and one of the side walls (e.g. between the hook head 21a and a rear edge of that side wall). A hook neck may connect the hook head 21a to the side wall or, in some versions, the hook neck may be considered to be part of the side wall or hook head 21a.
The hook gap 21b may include a wide mouth portion and a narrow inner portion (as in
The hook head 21a is configured to be received by a hook aperture 122a of the support member 12 and the hook gap 21b is then configured to receive part of the wall of the support member 12 to retain the bracket 2 on the support member 12.
In some embodiments there may be multiple hooks 21 provided in one or more pairs of hooks 21. These may be an upper pair and may also include a lower pair of hooks 21. The upper pair may be located towards the second end of the bracket 2 and the lower pair may be located towards the first end of the bracket 2, for example. Each hook 21 of a pair of hooks 21 may extend rearward from a different side wall of the bracket 2 and each hook 21 of a pair of hooks 21 may be at substantially the same height with respect to the side wall.
Accordingly, the hook apertures 122a of the apertures 122 of the support member 12 may be arranged (i.e. provided) in pairs—corresponding with the hooks 21 of the bracket 2. In other words, the hook apertures 122a in two-by-two grouping. However, this need not be the case and, indeed, two adjacent hooks 21 may be received by one hook aperture 122a in some versions (and so hook apertures 122a may be provided in a one-by-two (or more) array).
In some versions, whilst hook apertures 122a have been described as individual apertures, it may be that a single aperture is provided which defines two (or more) hook apertures 122a. In other words, the support member 12 may define an aperture which includes a plurality of hook aperture parts, each of which acts as a hook aperture 122a as described herein. In other words, two or more hook apertures 122a (which may be hook apertures 122a of the same securing location) may be interconnected apertures (e.g. joined together to form one multi-part aperture). This need not, however, be the case and each hook aperture 122a described herein may be a separate (e.g. distinct) aperture 122a.
The hook apertures 122a may, therefore, in some examples, include upper and lower pairs of apertures, for example. In some embodiments, the hook apertures 122a are provided in groups of four, with each group of four including a first pair and a second pair located at different points along the length of the support member 12 (but closer to each other than to any other hook apertures 122a). There may be an upper group of four hook apertures 122a and a lower group of four apertures 122a, for example. In some such embodiments, the upper pair of hooks 21 of the bracket 2 may be received by the first (i.e. uppermost) pair of the upper group of four hook apertures 122a and the lower pair of hooks 21 of the bracket 2 may be received by the second (i.e. lowermost) pair of the lower group of four hook apertures 122a or, in some versions, by the first (i.e. uppermost) pair of the lower group of four hook apertures 122a. Other configurations of hook apertures 122a may be provided. For example, hook apertures 122a may be provided as a generally equally spaced array of hook apertures 122a along a length of the support member 12.
The bracket 2 may further include a catch mechanism 22 (this may be provided in versions with each single hook 21 received by a single hook aperture 122a, or in relation to versions in which more than one hook 21 is received by the same hook aperture 122a). The catch mechanism 22 may include a catch member 22a and a barrel 22b. The barrel 22b may be mounted to one of the side walls of the bracket 2, for example. The barrel 22b may be mounted in a fixed position with respect to the side wall of the bracket 2. The barrel 22b may be configured to receive the catch member 22a and to guide movement of the catch member 22a between a retracted and an extended position relative to the barrel 22b. The catch mechanism 22 may include a resilient biasing arrangement (not shown) such as a spring (which may be a helical spring) configured to bias the catch member 22a into the extended position with respect to the barrel 22b.
The catch member 22a may have a first end which is located towards the rear of the bracket 2 and a second end which is located towards a front of the bracket 2.
The extended position of the catch member 22a may be such that it projects more rearward than it does when in the retracted position.
The second end of the catch member 22a may, therefore, include a handle or handle section to enable the catch member 22a to be pulled (e.g. manually) into or towards the retracted position (i.e. forward with respect to the bracket 2).
The catch mechanism 22 may be configured such that, with the catch member 22a in the extended position and the or each hook 21 engaging the support member, the catch member 22a is received, in part, by a catch aperture 122b of the support member 12. The catch aperture 122b is, therefore, positioned to enable the receipt of the catch member 22a in this manner. With the catch member 22a in the retracted position, however, the catch member 22b may be drawn clear of the catch aperture 122b.
In some embodiments, the catch mechanism 22 and so the catch member 22a is located between the two pairs of hooks 21 (in embodiments in which two pairs of hooks 21 are provided) and may be closer to the upper pair than the lower pair, for example.
The catch barrel 22b may be, for example, welded or otherwise secured to the side wall of the bracket 2.
Accordingly, the bracket 2 may be secured to the support member 12 in a releasable manner, with the catch mechanism 22 hindering or substantially preventing accidental removal of the bracket 2 from the support member 12. The bracket 2 may be so secured, in some embodiments, at a plurality of different locations along a length of the support member 12.
In some versions there may be no catch mechanism 22.
In some versions, the or each hook aperture 122a includes a narrow part (which may be an upper part) and a wide part (which may be a lower part)—upper and lower being in relation to the position with the support member 12 in its normal in use configuration.
A distance between outer surfaces of the or each bracket 2 is a thickness of the bracket 2. In
The wide part of the or each hook aperture 122a may be wider than or substantially the same as the thickness of the bracket 2. This wide part is, for example, indicated in
The or each hook aperture 122a may be sized to receive the hook head 21a of a bracket 2 therethrough and, in some versions, two such hook heads 21a from an adjacent pair of hook heads 21a. The or each hook aperture 122a may have a height which is, therefore, larger than a height of the hook head 21a or heads 21a to be received therethrough. The height of the wide part of the or each hook aperture 122a may, however, be smaller than the height of the hook head 21a or heads 21a, such that at least part of the hook head 21a or heads 21a must be received through the narrow part of that hook aperture 122a. Accordingly, in some versions, in order to fit the bracket 2 to the support member 12 the thickness of the bracket 2 needs to be reduced to the width of the narrow part of the or each hook aperture 122a. This may be achieved, for example, by resiliently flexing the side walls of the bracket 2 towards each other (i.e. by pressing the side walls of the bracket 2 towards each other). This may be achieved, for example, by applying a clamping force to the bracket 2. In such a manner the bracket 2 may be fitted to the support member 12 with hook heads 21a of a pair of adjacent hooks 21 passing through a hook aperture 122a. The clamping force on the bracket 2 may then be released. This may cause the side walls of the bracket 2 to return, resiliently, to substantially their original position (or to a position dictated by the hook aperture 122a which received them).
If this clamping force is removed with a wall of the support member 12 received by the hook gap 21b and an edge of that wall engaging the bracket 2 (e.g. with the edge of the wall of the support member 12 engaging the hook neck), then the height of the wide part of the hook aperture 122a and the thickness of the bracket 2 (i.e. the distance between the outer surfaces of the side walls) being greater than the width of the narrow part of the hook aperture 122a, is such that the bracket 2 is substantially prevented from being removed from the support member 12 without re-applying the aforementioned clamping force to reduce that thickness resiliently such that the hook heads 21a can pass through, at least partially, the narrow part of the hook aperture 122a.
The neck portion of the or each hook 21 may have a size substantially equal to or less than the height of the wide part of the hook aperture 122a, for example.
This may, therefore, enable the bracket 2 to be securely fitted to the support member 12 without the need for a catch mechanism 22 (although one may also be provided).
The bracket 2 of
Removal of the bracket 2 from the support member 12 can be achieved by the reverse process (e.g. the application of the clamping force to reduce the thickness of the bracket 2, resiliently, to enable its removal at least partially through the narrow part of the hook aperture 122a).
Whilst some versions use one hook aperture 122a to receive two hooks 21 of a pair of adjacent hooks 21, and to be secured in place by virtue of the narrow part of the hook aperture 122a substantially preventing removal of the hooks 21, it is also possible for the same effect to be achieved using two hook apertures 122a—each configured to receive a respective one of the pair of hooks 21. In such versions, the wide and narrow parts of the hook aperture 122a are effectively defined by the distance between the respective outer side edges of the two hook apertures 122a.
Accordingly, in some versions, there may be at least one hook aperture 122a configured to receive a pair of adjacent hooks 21. The at least one hook aperture 122a may include a first outer side edge and a second outer side edge (which may be edges of the same aperture 122a or different but adjacent apertures 122a). The first and second outer side edges may define a wide part and a narrow part, as described above and may be opposing edges.
The clamping force required to reduce the thickness of the bracket 2 sufficiently to enable its secure fitting to the support member 12 as described may be applied using a tool 4 (a version of which is depicted in
In some versions, with reference to the bracket 2 in
The or each hook aperture 122a may, therefore, be sized to receive the hook head 21a of a bracket 2 therethrough and, in some versions, two such hook heads 21a from an adjacent pair of hook heads 21a. The or each hook aperture 122a may have a height which is, therefore, larger than a height of the hook head 21a or heads 21a to be received therethrough.
The bracket 2 in some such versions may include a threaded aperture 24. The threaded aperture 24 may be provided in one of the side walls of the bracket 2 and may be located towards one end (e.g. the first end (which may be the lower end in normal use)). The threaded aperture 24 may be provided, for example, by the attachment (e.g. through welding) of a nut to a first tab which extends from the bracket 2 (e.g. from one of the side walls of the bracket 2). The threaded aperture 24 may, therefore, be defined by a first of the side walls of the bracket 2 and/or by a female threaded member (such as the nut) attached thereto. The threaded aperture 24 is configured to receive a male threaded member 25 (such as a bolt) therethrough (which is correspondingly threaded with respect to the threaded aperture 24), with rotation of the male threaded member 25 within the threaded aperture controlling the degree of extension of the male threaded member 25 with respect to the first of the side walls. A part of an opposing side wall (e.g. a second side wall) of the bracket 2 may face the threaded aperture 24. This part may be a tab thereof (e.g. a second tab), which may extend from one end of the bracket (e.g. the first end (which may be the lower end in normal use)). Accordingly, when the male threaded member 25 is extended sufficiently (e.g. by rotation with respect to the bracket 2) it will abut the part of the opposing side wall. Continued extension of the male threaded member 25 (e.g. by rotation with respect to the bracket 2) will cause the first and second side walls to move apart. This will, therefore, increase the thickness of the bracket 2.
Accordingly, in some versions, in order to fit the bracket 2 to the support member 12, the bracket 2 may be fitted to the support member 12 with hook heads 21a of a pair of adjacent hooks 21 passing through a hook aperture 122a. The bracket 2 may be manoeuvred such that the adjacent hooks 21 are located in the wider part of the hook aperture 122a. The thickness of the bracket 2 may then be increased (using the threaded aperture 24 and male threaded member 25) such that the thickness exceeds the width of the narrow part. The height of the hook head 21a may be larger, in some such versions, than a height of the wide part of the hook aperture 122a and so the bracket 2 may then be trapped and so inhibited from removal. In some versions, the thickness of the bracket 2 may be increased such that the side walls about the edges of support member 12 defining the hook aperture 122a and this may help to brace the bracket 2 (e.g. inhibiting rotational movement of the bracket 2 with respect to the support member 12).
Removal of the bracket 2 from the support member 12 may entail the rotation of the male threaded member 25 to retract it with respect to the threaded aperture 24 and so reduce the thickness of the bracket 2 to enable removal through the narrow (and wide) parts of the hook aperture 122a. As will be appreciated, the bracket 2 may be configured to return, resiliently, to it narrower thickness.
This may, therefore, again enable the bracket 2 to be securely fitted to the support member 12 without the need for a catch mechanism 22 (although one may also be provided).
As will be understood, in some versions, therefore, the bracket 2 (and, in particular, the side walls thereof) may be flexed (resiliently) outwardly to secure the bracket 2 to the support member 12, inhibiting or substantially preventing its removal. As described, some other examples may require the inward flexing (resiliently) of the bracket 2 (and, in particular, the side walls thereof) to fit the bracket 2 to the support member 12. This flexing may be flexing about the further wall of the bracket 2 to move the side walls towards (in the case of inward flexing) or away (in the case of outward flexing) from each other. This flexing is resilient in that the side walls are biased towards a neutral state (from which position the side walls are moved with respect to each other). As will be understood, this movement may be rotational movement about the further wall and each side wall may rotate about a respective axis defined by the juncture between that side wall and the further wall. Accordingly, the movement of one side wall with respect to the may be movement of distal ends of the side walls with respect to each other (the distal ends being remote from the further wall). In other words, the movement may be movement of the hooks 21 in each pair, if provided, away and towards each other (i.e. with respect to each other).
In some versions, the side walls of the bracket 2 may include apertures 26 therethrough (see
In some versions, therefore, one or more support members 12 may be provided with each support member 12 including one or more securing locations along a length thereof. In some versions there are a plurality of support members 12 which are substantially identical. The or each support member 12 may be provided in a kit with one or more other components, in any combination, described herein.
The or each securing location may include, for example, a plurality of hook apertures 122a, with each hook aperture 122a configured to receive one or more hooks 21 of the bracket 2. In some versions, each hook aperture 122a is configured to receive two hooks 21 (although this need not be the case). There may be securing locations provided on multiple sides of the support member 12 at the same distance along the length thereof. In the case of a support member 12 with a square cross-section, for example, there may be one such securing location on each of the four sides thereof at the same distance along the length (i.e. distance from an end).
The support member 12, for example of
In some versions, the support member 12 may be a handrail support member 12 and an example is depicted in
The support member 12 in the form of a handrail support member 12 may be fitted to the end of a support member 12 which is in the form of a leg member. To achieve this a connection member 6 (or spigot) may be provided. Examples of the connection member 6 are shown in
The connection member 6 may include a first elongate plate 61 to which may be mounted second and third elongate plates 62,63. The first, second and third elongate plates 61,62,63 may be mounted such that their longitudinal axes are all generally parallel with each other but with the second and third elongate plates 62,63 perpendicular to the first elongate plate 61. The first, second, and third 61,62,63 elongate plates may, therefore, form a connection member 6 with a cross-shaped cross-section (and the second and third elongate plates 62,63 may be located generally halfway across a width of the first elongate plate 61). The first elongate plate 61 may be longer than the second and third elongate plates 62,63. At one or both ends, the first elongate plate 61 may, therefore, extend beyond the second and third elongate plates 62,63 (which may be generally aligned with each other and may be of substantially the same length). The second and third elongate plates 62,62 may be welded to the first elongate plate 61.
The connection member 6 may be inserted into an upper end of the support member 12 which is in the form of a leg member and into the lower end of the support member 12 which is in the form of a handrail support member—see
The connection member 6 may define at least one aperture 611 which may be defined by an end of the first elongate member 61 (e.g. the end which extends beyond the second and third elongate members 62,63). A pin, bolt, or other member, may be passed through, for example, an aperture (such as the further aperture 123) in the support member 12 (which may be the support member 12 in the form of a leg member) and through one of the at least one aperture 611 of the connection member 6 to secure the two pieces together. In some versions, see
The cross-shape of the connection member 6 may help to reduce the risk of interference with any brackets 2 connected (or to be connected) with the support member 12. The upper support member 12 (e.g. the handrail support member 12) may be slotted on to the end of the connection member 6 and may be held in place by gravity or one or more pins, bolts or other members. In some versions, there may be a slot 124 or aperture 124a defined in the support member 12 (e.g. the handrail support member 12) towards one end thereof (e.g. the lower end) which enables welding and/or visual inspection of the connection member 6 within the support member 12 (e.g. within the handrail support member 12). In some versions the slot 124 or aperture 124a is used to secure a kick plate to the support member 12 (using a bolt or the like).
A thickness of the first and/or second and/or third elongate plate 61,62,63 may be less than the distance between two adjacent hooks 21 of the bracket 2 (such that the elongate plate 61,62,63 can pass therebetween when the bracket 2 is connected to the support member 12). This can be seen in
In some versions, the connection member 6 may include a collar 64 which may be located around at least part of the first elongate member 61, and/or the second elongate member 62, and/or the third elongate member 63. The collar 64 may be of the same external cross-sectional shape as an internal cross-sectional shape of the support member 12—e.g. a square cross-section. The collar 64 may be configured, in some versions, to slide into the support member 12 but in some versions may be configured to abut the end of the support member 12. In the former case, the collar 64 may aid the alignment of the connection member 6 within the support member 12 and in the latter case the collar 64 may allow the connection member 6 to sit atop a support member 12 without necessarily requiring the use of a pin or the like through the aperture 611.
In some versions, with
In some such versions, the lower end of the tubular insert section 65 (i.e. the end which is located along the length of the connection member 6) may include one or more cut-outs (which may be generally rectangular in shape). The or each cut-out may provide access to the space around at least part of the first, second, and/or third elongate member 61,62,63. As described, the hooks 21 may pass either side of the first, second, and/or third elongate members 61,62,63 when the connection member 6 is fitted to a support member 12 and one or more brackets 2 are also fitted to the support member 12. Therefore, the or each cut-out may permit an uppermost of the hook apertures 122a (or more than one uppermost hook aperture 122a) to be used to fit a bracket 2 when a connection member 6 is fitted to the support member 12 (as the tubular insert section 65 may otherwise block this in some versions).
The collar 64 may be provided around at least part of the tubular insert section 65, for example. The collar 64 may be provided between the or each cut-out and an end of the tubular insert section 65 (which may be the end of which is also the end of the connection member 6).
The tubular insert section 65 may define one or more pin apertures 651. In some versions, each side of the tubular insert section 65 defines at least one pin aperture 651. The or each pin aperture 651 may be located towards the end of the tubular insert section 65 which may be the end of which is also the end of the connection member 6. In some instances, therefore, this is a position above the collar 64 (with the connection member 6 in its normal in use orientation).
The tubular insert section 65 may be at least partially received by an end of a support member 12, which may then about the collar 64. As described, the other end of the connection member 6 may be at least partially received by another support member 12, which may abut the collar 64. The receipt of the tubular insert section 65 and other end of the connection member 6 by support members 12 may be telescopic receipt, for example. The collar 64 may, therefore, be sandwiched between the two support members 12 on the ends of the connection member 6. The tubular insert section 65 may provide a relatively close fit with the support member 12 to restrict unwanted lateral movement between the two. One or more pins may be used to secure the connection member 6 to either or both support member 12—e.g. using the aperture(s) 611, pin aperture(s) 651, slot(s) 124 or aperture(s) 124a, and/or further aperture(s) 123.
In some versions, the connection member 6 may be secured to the support member 12 in an irremovable manner (e.g. to form the first end configuration 12a). The connection member 6 may be secured to the support member 12 by welding, for example.
In some embodiments, brackets 2 may be connected to opposing ends of a diagonal cross-brace member 3. The diagonal cross-brace member 3 may be elongate and may be formed from box section material, for example. The diagonal cross-brace member 3 may be welded, for example, to two brackets 2 (one at either end thereof). The connection may be a diagonal connection such that, with one of the two brackets 2 connected to a first support member 12 and the other of the two brackets 2 connected to a second support member 12 (the two support members having offset longitudinal axes—i.e. being horizontally spaced apart), the diagonal cross-brace member 3 extends diagonally between the two support members 12.
The hooks 21 of the brackets 2 have been found to be particularly good as forces applied to the bracket 2 are normally downward (e.g. gravity) and this keeps the hooks 21 engaged. The receipt of the fin 116 in the slot of the bracket 2, particularly a tapering fin 116 and slot, also drive (under gravity) parts into engagement. The open ended slot of some embodiments means that the bracket 2 can be used with different lengths of fin 116 and/or that the bracket 2 (excluding the catch mechanism 22) can be readily manufactured from sheet material.
Various of the figures include dimensions and these are given in mm. The dimensions given are by way of example only and should be viewed as just one version of what is depicted in those figures—i.e. the figures should also be viewed as being representative of versions with different dimensions but the same features.
In some embodiments, the provision of the hooks 21 as extensions of the side wall material makes for simpler and cheaper manufacturing.
Similarly, the use of end plates 115 and/or hook portions 113a in the construction of the decking members 11 simplifies the construction without compromising the strength of the decking member 11.
Some versions provide multiple different options of the securing of brackets 2, legacy brackets 7 and handrails 5 to the support members 12. This provides a number of options and allows existing or old stock of equipment to be used (e.g. from earlier system versions).
The components of the modular platform system 1 may each be formed from metal and that metal may be steel.
References hereinto upper, lower, uppermost, lowermost, top and bottom, and other orientation dependent descriptions, are in terms of the normal in use orientation of the element concerned.
In some versions, there is a method provided of using the above described versions of the technology in the manners described (e.g. to fit or remove a bracket 2 from a support member 12 and/or to fit a decking member 11 and/or handrail 5).
