Description

TITLE: A kit for a barrier system This invention relates to temporary barricades or barrier systems which may be erected and dismantled as desired or necessary. More specifically, the present invention relates to a (portable) barrier kit as well as a temporary barrier (system) erectable therefrom. A
barrier system, erectable from the kit, may be used for temporarily barricading dangerous areas such as elevated floor side edges, holes, openings, etc.

A barrier system of the present invention (including a kit therefore) may by way of example be exploited in relation to building construction sites. However, a barrier system of the present invention (including a kit therefore) may be used in relation to other environmental contexts where a barrier is desired; e.g. in any area where a barricade may be sought for example to prevent entry into unauthorized or dangerous areas.

In the (building) construction industry some type of barrier or barrier system is invariably needed to prevent people as well as objects from entering a danger zone and in particular from falling from dangerous heights. Thus, for example, during the construction of a multi-floor building, it is common to first put in place the floors, ceilings and intermediate support pillars or posts interconnecting the floors and ceilings;
stairwells, elevator shafts, etc. are also put in place. Thereafter the outer and inner side walls for the floors are put in place. However, the period during which floor sidewalls are not yet in place represents a particularly dangerous time, since there is an ever present risk that people may accidentally pass over unguarded floor side edges or through floor openings and fall to their injury or even death. There is also an ever present risk that objects may also accidentally pass (e.g. be kicked) over unguarded floor side edges or through floor openings and fall below risking injury or even death to unwary persons below.

Barriers are known which comprise some type of rigid fencing (e.g. rigid rails) components. The various components of such known rigid barriers are relatively heavy and bulky. Such known types of rigid barriers thus present transportation and storage challenges as well as challenges related to the erection and removal thereof with respect to a given worksite. For example, since the rigid components of such known rigid barriers are heavy and bulky there is a significant storage space requirement as well as transportation requirement (i.e. to and from a worksite). Examples of rigid barriers with rigid rail members may be seen in US patent nos. 6,015,139; 6,336,623; and 7,338,033.
Barriers are also known which comprise some type of flexible fencing (e.g.
flexible rail) components. Examples of barriers with flexible rail members may be seen in US
patent nos. 3,880,405 (strap rail); 4,480,819 (cable rail); and 6,336,623 (cable rail).

Barriers are further known which comprise some type of flexible fencing (e.g.
rail) components which include means for subjecting the flexible rail component to tension.
Examples of barriers with tensioned flexible rail members may be seen in US
patent nos.
406,642; 997,725; and 6,053,281.

A portable barricade is in particular disclosed in US patent application no.

published under US 20080173854. The portable barricade has a plurality of horizontally extending straps. The horizontally extending straps are attached to the provided support poles. The horizontally extending straps may be set to a desired tension between terminal support poles by a disclosed tension producing ratchet device(s). The barricade also has a plurality of vertical straps which are disposed between and interconnect the horizontal straps.

However, a problem with respect to known barriers or barricades having strap-rail members (i.e. flexible elongated members) is that (even under tension) such a strap-rail member in the region spanning between terminal structural support members may undesirably sag or more significantly be displaced downwardly under the weight of a person or heavy object. Such downward displacement can effectively defeat the barrier function of the strap-rail member and lead to undesired injury, spill over, etc. It would be advantageous to have a barrier system which could attenuate or avoid such intermediate sagging of the strap-rail member.

A further problem with respect to known barriers is that rail support structures are provided by the barrier system itsel It would be advantageous to be able to have a barrier system that could exploit the in-situ support columns or posts presently available as rail support structures (i.e. in particular as terminal anchor element(s)).

Accordingly it would be advantageous to have a barrier system which may be relatively easily erected and thereafter dismantled; which can attenuate intermediate strap-rail member sag; and/or which may exploit in situ posts (or columns), walls and the like as (e.g. terminal) support members for the barrier.

It would be advantageous to have means for automatic or controlled disposition of the strap-rail member at a(predetermined) height relative to an underlying support structure (e.g. floor, ground etc.) as may be required to conform to safety regulations.

It is further well known in the art that safety barriers typically have to conform to certain government safety regulations, and even regulations maintained by owners of properties or structures.

It would be advantageous to have a removeable barrier system which is easy to erect and dismantle and which may be configured to comply with government guidelines for barriers or barricade systems.

Thus the present invention, as described herein, relates not only to a (removeable or temporary) barrier system itself but also to a kit for the construction of such a (removeable or temporary) barrier system. In other words, a barrier system as described herein may be erected and dismantled as desired or necessary.

A barrier system as described herein may, for example, be designed as a safety barrier meeting government regulations for the prevention of damage to equipment as well as injuries to persons.

It to be understood herein that the terms "strap means", "strap member" and the like refer to an elongated object of pliant material which has sufficient flexibility so as to be able to be rolled or coiled up and includes without limitation such objects in the form of a web, strap, band, strip, ribbon, rope, line, cable, chain or the like. It is further to be understood herein that any "strap means", "strap member" and the like may (keeping in mind the purpose thereof) be of any (suitable) metallic, plastic, composite material, as well as any combinations thereof. Thus for example a strap member may be manufactured of woven type material and may, for example, have a form similar to a seat belt.
Any such woven type of material is of course to be formed so as to provide the elongated object with characteristics lending itself to the prevention of persons and/or objects such as equipment from passing therethrough.

It is to be understood herein that the expression "height support member" as used in relation to a "strap member", a "strap anchor segment", and the like, refers to a member which is rigid as defined herein.

Thus it is in particular to be understood that as used herein the word "rigid"
characterizes an element, member, component, segment, etc. as at least being able to resist deformation thereof (i.e. compression, bowing or otherwise) when subjected to compressive forces as well as bending forces in the context of the use to which a strap support element (of the barrier as herein described) is to be put - i.e. in order to resist vertically downward displacement of the strap member - including but not limited to being incapable of bending.

Thus in accordance with the present invention, a height support member of a strap-support component is for example to be understood as being resistant to compression and/or bending.

It is to be understood herein that the expression "predetermined height level"
includes not only a specific height (e.g. above a support such as the ground, a floor or other equivalent surface) but a height range as well. For example, the expression "predetermined height level" includes a height which is equivalent to a desired or necessary height above for example a floor; in other words, this expression includes any height (e.g.
range) which for all intents and purposes is acceptable, keeping in mind the purposes of a desired or necessary barrier system.

It is further to be understood that as used herein the expression "pillar member" is to be understood as comprising any type of vertically extending (e.g. existing) support whatsoever whether free standing or disposed between horizontal structural and/or floor members (e.g. pillar, column, piling, post, and the like).
Furthermore as described herein a (tensioned) length of strap member may span the distance between "terminal" pillars which may optionally be further separated by one or more intermediate pillars so that any elevation support elements may not only be disposed between terminal pillars but also be associated with (i.e. attached to) intermediate pillars.

Additionally, unless otherwise indicated or dictated by the context of the following description of the present invention, it is to be understood that a kit or barrier system may be exploited by having recourse to tensioning (i.e. ratcheting) devices which may be commercially available; see also the above mentioned patent documents for particular examples of tensioning (i.e. ratchet) type devices.

Thus in accordance with an aspect, the present invention relates to a barrier kit for the construction of a removable barrier system wherein said barrier system comprises an anchor component fixed to an underlying support structure, said kit comprising a barrier component, said barrier component comprising a removable strap-rail component said removable strap-rail component comprising strap means, anchor attachment means configured for the releasable attachment of a length (i.e. span or section) of the strap means to said anchor component, and tensioning means for releasable tensioning of said length (i.e. span) of said strap means when said length (i.e. span) of the strap means is attached to said anchor component by said anchor attachment means said kit further comprising height stabilization means for releasably maintaining the strap means at a predetermined height level relative to (i.e. above) said underlying support structure at one or more predetermined points along the tensioned length (i.e.
span) of said strap means when said strap means is tensioned by said tensioning means.

In accordance with the present invention a span height stabilization means may for example comprise clamp means. The clamp means may take any suitable form in mind the purpose thereof as described herein. The clamp means may for example comprise a first clamp member, a second clamp member, and clamp adjustment means for displacement of the first and second clamp members relative to each other for engagement and disengagement of said strap means therebetween.
In accordance with another particular aspect the present invention provides a barrier kit for the construction of a removable barrier system wherein said barrier system comprises an anchor component comprising two or more anchor elements fixed to an underlying support structure, said kit comprising a barrier component, said barrier component comprising a removable strap-rail component and a removable strap-support component, said removable strap-rail component comprising a strap member, a first anchor attachment member, and a second anchor attachment member, said anchor attachment members being configured for the releasable attachment of a length (i.e. span) of the strap member to said anchor component, said removable strap-rail component further comprising tensioning means for releasable tensioning of said length (i.e. span) of strap member when said length of strap member is attached to said anchor component by said first and second anchor attachment members wherein said removable strap-support component comprises at least one elevation support element comprising a height support member (or segment) and a releasable strap engagement member connected to said height support member, said height support member comprising a ground engagement element for engagement with said underlying support structure, and wherein said releasable strap engagement member and said height support member are configured such that said releasable strap engagement member is disposed to releasably maintain said length of strap member at a first predetermined height level relative to said underlying support structure when said length of strap member is tensioned by said tensioning means.

In accordance with the present invention an anchor component may take any form whatsoever keeping in mind the purpose thereof as described herein. An anchor component may for example comprise in situ components of a (building) structure (e.g. a wall type structure). An anchor component may for example comprise in-situ (floor) support columns/posts) fixed to the underlying support structure of a building. For example, the anchor component may comprise anchor elements wherein one (or more) of the anchor elements comprises a (e.g. in situ) pillar member. Thus in accordance with the present invention when one (or more) of the anchor elements comprises a pillar member, there may also be provided means for releasable attachment of at least one of said span support elements to a respective pillar member. In any event, the anchor component as mentioned above may take any form whatsoever keeping in mind the purpose thereof as described herein, i.e. to provide an anchor for tensioning purposes.

As mentioned the present invention further relates to a barrier system itself.
Thus in accordance with another aspect the present invention provides a removeable barrier system comprising an anchor component and a barrier component, said anchor component comprising two or more anchor elements fixed to an underlying support structure, one or more of said anchor elements comprising a pillar member, said barrier component comprising a removable strap-rail component and a removable strap-support component, said removable strap-rail component comprising a strap member, a first anchor attachment member, and a second anchor attachment member, said anchor attachment members releasably attaching a length (i.e. span) of the strap member to said anchor component, said removable strap-rail component further comprising tensioning means releasably tensioning said length (i.e. span) of strap member attached to said anchor component by said first and second anchor attachment members wherein said removable strap-support component comprises at least one elevation support element comprising a height support member and a releasable strap engagement member connected to said height support member, said height support member comprising a ground engagement element engaging said underlying support structure, and wherein said releasable strap engagement member and said height support member are configured such that said releasable strap engagement member is disposed to releasably maintain said tensioned length of strap member at a first predetermined height level relative to said underlying support structure at a predetermined point along the tensioned length of said strap member.

It is to be understood herein that in accordance with the present invention, an elevation support element may be configured so as to maintain a strap member at any desired or necessary height level; for example a height level determined by an individual site or by government regulation.

In accordance with the present invention a barrier component may as desired or necessary comprise one or more strap-rail components exploited in association with one or more common elevation support elements.

Thus in accordance with the present invention a barrier component may comprise a further (i.e. second) removeable strap-rail component as defined herein, said further strap-rail component being a second strap-rail component comprising a respective tensioning means for releasable tensioning of a respective length (i.e. span) of the respective strap member thereof when said length of said respective strap member is attached to said anchor component by respective first and second anchor attachment members of said second strap rail component, wherein said elevation support element of the removable strap-support component comprises an additional (i.e. second) releasable strap engagement member, and wherein said additional releasable strap engagement member and said height support member are configured such that said additional releasable strap engagement member is disposed to releasably maintain the respective length of the strap member of the second strap-rail component at a second predetermined height-level below said first predetermined height-level when said respective length of strap member is tensioned by the respective tensioning means of said second strap rail component.
In accordance with the present invention the second strap-rail component may be a toe-strap rail component, and the additional releasable strap engagement member and said height support member may be configured such that said additional releasable strap engagement member is disposed to releasably maintain the respective length of the strap member of the toe-strap rail component at a second predetermined height-level below said first predetermined height-level and adjacent said underlying support structure.

In accordance with the present invention a barrier system may be based on one or more barrier components. Thus in accordance with the present invention a barrier system may for example be based on three of the barrier components, wherein one of said barrier components is a top-rail barrier component, another of said barrier components is a toe-rail barrier component and the remaining barrier component is a mid-rail barrier component, wherein the elevation support element of the top-rail barrier component comprises a releasable top-rail strap engagement member, the releasable top-rail strap engagement member and the height support member of the top-rail barrier component being configured such that the releasable top-rail strap engagement member of the top-rail barrier component is disposed to releasably-maintain the strap member of the top-rail barrier component at said first predetermined height-level, wherein the elevation support element of the mid-rail barrier component comprises a releasable mid-rail strap engagement member, the releasable mid-rail strap engagement member and the height support member of the mid-rail barrier component being configured such that the releasable mid-rail strap engagement member of the mid-rail barrier component is disposed to releasably maintain the strap member of the mid-rail barrier component at a second predetermined height-level, said second predetermined height-level being below said first predetermined height-level, wherein the elevation support element of the toe-rail barrier component comprises a releasable toe-rail strap engagement member, the releasable toe-rail strap engagement member and the height support member of the toe-rail barrier component being configured such that the releasable toe-rail strap engagement member of the toe-rail barrier component is disposed to releasably maintain the strap member of the toe-rail barrier component at a third predetermined height-level, said third predetermined height level being below said second predetermined height-level and adjacent said underlying support structure.

In accordance with the present invention, as desired or as necessary, a barrier system may exploit or be based on the exploitation of a common elevation support element (i.e. one or more such elements) which defines the elevation support element of each of the top-rail, mid-rail and toe-rail barrier components.

In accordance with the present invention a ground engagement member may take any form whatsoever keeping in mind its purpose as described herein. A ground engagement element may simply be configured for abutting (i.e. unfixed) engagement with the underlying support structure; alternatively a ground engagement element may be configured for being releasably fixed (in any suitable manner, e.g. be provided with a foot member boltable ) to an underlying support structure. However, abutting engagement is an advantageous structure since it facilitates minimal installation and dismantling steps.
In accordance with the present invention, a releasable strap engagement member for a (e.g. at least the top-rail) barrier component may comprise clamp means, said clamp means comprising a first clamp member, a second clamp member, and clamp adjustment means for displacement of the first and second clamp members relative to each other for engagement and disengagement of said strap member there between. In accordance with the present invention, a height support member may define one of such clamp members.
In accordance with the present invention an anchor component may, for example, (i.e. in relation to a strap-rail component) comprise one or two terminal anchor elements and optionally as desired or as necessary one or more intermediate anchor elements disposed between terminal anchor elements. A length of strap member may be tensioned between respective terminal anchor elements (which may be the same or different) to which the length strap member is attached by the respective anchor attachment members;
i.e. if two or more strap members are exploited the terminal anchor elements may be the same or different.

In accordance with the present invention each of the anchor attachment members may be configured (in any (suitable) manner whatsoever) for the releasable attachment of the (tensioned) length of strap member to a respective anchor element (which may be a terminal anchor element). A height location means may also be provided for releasable maintenance of the length of strap member at a first predetermined height level at least adjacent to (e.g. at) said respective terminal anchor element. The height location means may take any desired or necessary form. Such height location means may, for example, take the form of an elevation support element as described herein.

As mentioned an anchor element may comprise a pillar member. Thus in accordance with the resent invention each of the anchor attachment members may be releasably attach a (tensioned) length of strap member to an anchor element which is a terminal anchor element comprising a pillar member; wherein said anchor component may comprise two of said terminal anchor elements; wherein each of said anchor attachment members may comprise a strap anchor segment defining a girdle element about said pillar member; and wherein each of said anchor attachment members may comprise a strap attachment element attaching said girdle element to the strap member. A girdle element may for example take the form of a loop, noose, ring, eye, or the like which is disposable about a pillar member or the like for embracing/surrounding/encircle/girdle engagement of the pillar member or the like.

In accordance with the present invention a strap member may comprise the strap anchor segment of one or both anchor attachment members. Alternatively, a strap anchor segment of one or both anchor attachment members may be separate from the respective strap member.

In accordance with the present invention a barrier system may exploit an anchor component which may comprise two of the above mentioned terminal anchor elements, and wherein the removable strap-support component may further comprise two terminal support elements, wherein each of said terminal support elements comprises a terminal height support member for a respective strap anchor segment, each terminal height support member comprising a ground engagement element for engagement with said underlying support structure, wherein each of said terminal support elements further comprises a strap anchor segment engagement means connected to a respective terminal height support member, wherein a respective strap anchor segment engagement means and a respective terminal height support member are configured such that said respective strap anchor segment engagement means is disposed to releasably maintain the girdle element at said first predetermined height level above said underlying support structure.

In accordance with the present invention each of the terminal support elements may comprise means for releasable immobilization thereof to a respective terminal anchor element. As mentioned the strap anchor segment of each of said anchor attachment members may be separate from the strap member.

In accordance with the present invention a barrier system may, as mentioned, in addition to terminal anchor elements (i.e. which may be the same as or different for each barrier component) may exploit an anchor component which may further comprise one or more intermediate anchor elements comprising a respective pillar member. A barrier system may also further comprise means for releasable immobilization of at least one of said elevation support elements to the respective pillar member of one or more of said intermediate anchor elements.

In accordance with the present invention an anchor component may comprise two spaced apart terminal anchor elements, each of said terminal anchor elements (which may be defined by a separate respective anchor element) being fixed to the underlying support structure and wherein each anchor attachment member is configured for the releasable attachment of the strap member to a respective terminal anchor element. For this configuration an elevation support element(s) may be disposed independently between the terminal anchor elements.

In accordance with the present invention an anchor component may as desired or necessary further comprise one or more intermediate anchor elements disposed between the terminal anchor elements and wherein height location means may be provided for releasable maintenance of a strap member at a first (or other) predetermined height level adjacent to or at said terminal as well as at the intermediate anchor elements. For this configuration an elevation support element(s) may be disposed independently between the terminal anchor elements and the intermediate anchor elements as well as between intermediate anchor elements as the case may be.

Although two terminal anchor elements may be a usual configuration, an anchor component may comprise two or more spaced apart anchor elements but wherein the terminal anchor elements are defined by a common anchor element fixed to the underlying support structure (i.e. the terminal anchor elements are a shared (i.e.
common) anchor element).

As mentioned above the present invention may exploit a releasable strap engagement member (for the elevation support element of a strap-support component) which may comprise a clamp structure as mentioned herein. However, a releasable strap engagement member may take any desired or necessary form keeping in mind the function thereof.

A releasable strap engagement member may if desired comprise a closed loop such as a closed U-shaped member which is described below; however such a closed loop allows only for a longitudinal freedom of movement of a strap member through the strap aperture thereof. Thus a strap member would have to be longitudinally threaded thru the closed loop prior to anchoring of the strap member(s) to for example a pillar member as well as prior to tensioning of the strap member(s).

On the other hand, a releasable strap engagement member may if desired comprise a loop element which may be split by a strap opening (as described herein) which may allow for a second degree of freedom of movement of a strap member i.e. allow for lateral engagement of a strap member already attached to an anchor element or even if the strap member is already tensioned.

For example, a releasable strap engagement member may comprise grip means which may generally comprise a loop element. The loop element may define an aperture for (longitudinally) receiving the strap member but may also be split by a straight or by a convoluted lateral strap opening (i.e. slot, passageway, etc.) for lateral displacement of a strap member into and out of the aperture.

If the loop element is a convoluted lateral strap opening (i.e. slot, passageway, etc. ), the loop element and the strap opening may be configured such that lateral displacement of the strap member out of the loop aperture thru such a convoluted strap opening is inhibited (e.g. when the strap member is under tension). For this type of structure the loop element and said convoluted strap opening may be configured for sideways threading of the strap member through the convoluted the strap opening into and out of the aperture; in other words for this type of grip means, the strap member in un-tensioned state is to be deformed relative to the tensioned state thereof and in the deformed state may be passed into or out of the aperture defined by the loop element. The convoluted opening is however, configured such that when the strap member is in a tensioned state the convoluted nature of the lateral strap opening inhibits lateral or sideways displacement of the strap member out of the aperture of the loop element.

As mentioned the loop element may also be split by a straight lateral strap opening (i.e.
slot, passageway, etc.). An example embodiment of this type of grip means may take the form of simple U-shaped member. The open mouth of such U-shaped member may be disposed so at face upwardly when a strap member, under (horizontal) tension, is disposed in the aperture thereof. Such a grip means may rely on the tension of the strap member to maintain the strap member in the aperture of the loop element. If desired however, the elevated support element may be associated with lock means (e.g.
a padlock type mechanism) for closing off the mouth of the U-shaped member during use.
However, for example in the case of a toe-rail strap member the mouth of the U-shaped member may be disposed so as to face downwardly such that the U-shaped mouth is adjacent the underlying support structure, i.e. when a strap member, is under (horizontal) tension, the underlying support structure essentially block off the mouth of the U-shaped opening.

Alternatively a releasable strap engagement member may comprise grip means, the grip means comprising a loop element defining an aperture for receiving the strap member, said loop element being split by a strap opening dimensioned/configured for passage of the strap member through said strap opening into and out of said aperture, said grip means further comprising a closure means displaceable between an open position and a closed position, said loop element and closure means being configured for inhibiting displacement of the strap member out of said aperture thru said strap opening when the closure means is in said closed position, and said loop element and said closure means being configured such that when said closure means is in said open position, said strap opening is unobstructed by the closure means with respect to passage of the strap member thru said strap opening.

In particular, a releasable strap engagement member may comprise grip means wherein the grip means comprises a loop element defining an aperture for receiving the strap member, said loop element being split by a strap opening dimensioned/configured for lateral passage of the strap member through said strap opening into and out of said aperture, said grip means further comprising a lock swing arm mounted to the loop element for pivotal displacement between an open position within said aperture and a closed position, said lock swing arm being biased in said closed position, said loop element and said swing arm being configured for inhibiting displacement of the strap member out of said aperture thru said strap opening when the swing arm is in said closed position, and said loop element and said swing arm being configured such that when said swing arm is in said open position, said strap opening is unobstructed by the swing arm with respect to passage of the strap member thru said strap opening.

As an additional example a releasable strap engagement member may comprise grip means which may comprise a[displaceable] (i.e. slider) first grip element and a second grip element, said second grip element and said first grip elements being configured such that said first grip element is (e.g. Linearly) displaceable relative to said second element between a strap lock-in position and a strap release position wherein, when said first grip element is in said strap lock-in position, said second grip element and said first grip element define a closed loop element, said closed loop element defining an aperture for receiving the strap member, said closed loop element being configured for inhibiting sideways (radial) (i.e. lateral and vertical) displacement (passage) of the strap member out of the aperture defined thereby, wherein, when said first grip element is in said strap release position, said second grip element and said first grip element define an open loop element, said open loop element defining a respective strap aperture and being split by a strap opening dimensioned/configured for sideways displacement (passage) of the strap member through said strap opening into and out of said respective strap aperture, In accordance with an additional example a releasable strap engagement member means may comprise grip means which comprises a first slider grip element and a second grip element, said second grip element and said first slider grip elements being configured such that said first slider grip element is linearly displaceable relative to said second element between a strap lock-in position and a strap release position wherein, when said first slider grip element is in said strap lock-in position, said second grip element and said first slider grip element define a closed loop element, said closed loop element defining an aperture for receiving the strap member, said closed loop element being configured for inhibiting sideways (radial) (i.e.
lateral and vertical) displacement of the strap member out of the aperture defined thereby, wherein, when said first slider grip element is in said strap release position, said second grip element and said first slider grip element define an open loop element, said open loop element defining a respective strap aperture and being split by a strap opening dimensioned/configured for passage of the strap member through said strap opening into and out of said respective strap aperture.

In accordance with the present invention the above mentioned additional releasable strap engagement member may comprise grip means, said grip means comprising a loop element defining an aperture for receiving the strap member, said loop element being split by a strap opening configured for unobstructed sidewise/lateral passage of the strap member through said strap opening into and out of said aperture, said loop element and said strap opening being configured such that said strap opening is disposed for cooperation with the underlying support structure for inhibiting displacement of the strap member out of said aperture thru said strap opening.
Thus in accordance with the present invention the above mentioned a releasable strap engagement member of a common strap stabilizer support element for a toe-rail barrier component may comprise grip means, said grip means comprising a loop element defining an aperture for receiving the strap member, said loop element being split by a strap opening configured for unobstructed sidewise/lateral passage of the strap member through said strap opening into and out of said aperture, said loop element and said strap opening being configured such that said strap opening is disposed for cooperation with the underlying support structure for inhibiting displacement of the strap member out of said aperture thru said strap opening.
In accordance with the present invention, each releasable strap engagement member of a common elevation support element may comprises grip means, said grip means comprising a loop element defining an aperture for receiving the strap member, said loop element being split by a [straight/convoluted] strap opening (i.e. slot, passageway, etc. ), said loop element and said strap opening being configured such that displacement of the strap member out of said aperture thru said strap opening is inhibited, said loop element and said strap opening being configured for sideways threading of the strap member through said strap opening into and out of said aperture.

releasably bolted to an anchor wall and connected to top, mid and toe-rail strap members by carabiner type connectors.

In the following, unless indicated to the contrary or dictated from the context, common reference designations are used to designate common or similar elements.

Turning to figs. 1 and 2, these figures illustrate in schematic fashion the problem related to undesired displacement (i.e. vertical) of a tensioned strap (rail) member.

Fig. 1 and 2 illustrate (a length of) a strap member 1 which is (horizontally) tensioned (above a floor 2 or other similar type of support) in the direction of the horizontally outwardly pointing arrows 5 and 7. The ends of the strap member 1 are not shown but are each suitably anchored to a respective terminal anchor means such as for example a pillar or post member(s) or even a wall member(s) by suitable connectors, fasteners, etc.
Similarly the tensioning device for subjecting the (length of the) strap member 1 spanning the distance between the terminal anchor elements is not shown; the tensioning device may, for example, be any (known) tensioning device such as for example a device(s) as described in US published patent application no. US 20080173854 mentioned above or in any of the other above mentioned US patent documents.

Fig. 1 shows the tensioned length of strap member 1 in a vertically unstressed disposition wherein the length of strap member 1 shows no vertical deflection.
On the other hand, fig. 2 shows the tensioned length of strap member 1 of fig.
1 in a vertically stressed disposition wherein the length of strap member 1 shows vertical deflection in the direction of the deflection arrow 9, i.e. downwardly towards the floor 2.
Such deflection may be induced for example by the weight of a person being applied in unrestrained fashion to the length (of tensioned) strap member 1 in the direction of the deflection arrow. In the absence of some means to inhibit such deflection, the deflection may be significant enough to result in the person being able to undesirably pass over the strap member.

Referring to fig. 3, this figure illustrates in general fashion (by way of example only) an aspect of the present invention, namely a strap-support component which comprises an elevation support element indicated generally by reference numeral 11. The elevation support element 11 comprises a height support member 13 and a releasable strap engagement member 15. As may be seen the height support member 13 extends vertically in relation to the floor. The (length of) strap member 17 is under tension (see arrows 19 and 21) as in the case for strap member 1 of figs. 1 and 2. The height support member 13 has a ground engagement element 23 which in the embodiment shown is able to simply sit on or abut the floor 2 (e.g. is not fixed to the floor). The releasable strap engagement member 15 has the form of a closed loop which is defined by a closed U-shaped member. The closed loop defines a strap opening (for horizontally) receiving the strap member 17 in longitudinal (i.e. lengthwise) fashion, i.e. the strap member is longitudinally threaded thru the closed loop before the strap member is attached to the anchor structures (not shown) and before the strap member is tensioned. The closed loop is connected to the height support member 13 (e.g. by welds, bolts, and the like) and is disposed such that, with the ground engagement element 23 sitting on the floor, the strap member 17 is able to be maintained at a predetermined height leve125 relative to the floor in the face of a downward stress indicated by the arrow 27. As shown the predetermined height level 25 is indicated as being between the floor 2 and the underside of the tensioned (length of) strap member 17; the predetermined height level could of course be taken from the top side of the tensioned strap member 17 or some point between the bottom and top sides of the length of tensioned strap member 17.
The height support member 13 may be of a compression and/or bend resistant material (e.g. a metal such as aluminum, of a plastic material, etc.) such that it is able to provide a counterforce (indicated by arrow 29) to the downward stress indicated by arrow 27.

The closed loop defined by the closed U-shaped member inhibits (horizontal as well as vertical) lateral (or sidewise) displacement of the strap member 17 out of the strap opening (relative to the height support member); on the other hand horizontal (longitudinal) displacement of the strap member (in the direction of its length) through the strap opening is not inhibited by the structure of the closed loop. Other example embodiments of loop structures will be described below which while also inhibiting such lateral (or sidewise) displacement may allow for (manual) lateral displacement (i.e.
manipulation) of the strap member into or out of the strap opening.

If desired or necessary the ground engagement element 23 may, for example, comprise (i.e. be provided with or be releasably engageble with) a stabilizer member.
The stabilizer member may, for example, take the form of a foot member which may, for example, comprise a plate (not shown) or a counter weight such as shown for example in US patent no. 7,338,033. A plate may for example be provided with a relatively large undersurface which may abut the floor surface. Such a foot member may be provided when it is desired or necessary for augmenting vertical stability of the height support member, i.e. to inhibit the height support member from a tendency to (laterally) pivot or rotate about the longitudinal axis of the strap member 17. The foot member may for example have a (seating) cavity for releasable engagement with the tip end of the ground engagement member or element.

Fig. 4 illustrates an example barrier system having two barrier components, each barrier component comprising a respective independent elevation support element designated generally by the reference numerals 31 and 33. Each of the elevation support elements 31 and 33 has a respective height support member 35 or 37. Each of the elevation support elements 31 and 33 also has a respective releasable strap engagement member 39 or 41. As may be seen the elevation support members 35 and 37 extend vertically in relation to the floor 2. As in the case of the (length of the) strap member 1 of figs. 1 and 2, both of the (lengths of the) strap members 43 and 45 of fig. 4 are shown as being tensioned as indicated by the respective pairs of arrows 47 and 49 and 51 and 53. As shown upper strap member 43 may, for example, be part of a top-rail component (i.e. be a top-rail strap member) and the lower strap member 45 may be part of a lower-rail component (i.e. be a mid-rail strap member). Accordingly, as may also be appreciated the height support member (33, 35) of each elevation support element (31, 33) in conjunction with a respective closed loop attached thereto, may maintain a respective strap member 43 or 45 at a respective predetermined height level above the floor 2, namely a respective first upper height level 55 and a respective second lower height level 57 below the first height level.

As shown in fig. 4 each elevation support element and its corresponding height support member is distinct. Alternatively, the barrier system illustrated in fig. 4 may be adapted so as to exploit a common elevation support element which has a single or common height support member associated with two releasable strap engagement members disposed so as to be able to engage the two (horizontally offset) strap members.

Thus fig. 5 illustrates an alternate example embodiment which differs from that as shown in fig. 4 in that a single common height support member 59 is exploited to maintain the top-rail strap member 43 and the lower mid-rail strap member 45 at respective predetermined height levels. The common height support member 59 is associated with two releasable strap engagement members 61 and 63. The common height support member 59 has a ground engagement element 65 which in the embodiment shown also simple sits on or abuts the floor 2 (e.g. is not fixed to the floor). The dual engagement of both the upper and lower strap members connected to the common height support member 59 provides (vertical) stability to the vertically extending common height support member 59, i.e. the common height support member 59 is inhibited from a tendency to (laterally) pivot or rotate about the longitudinal axis of the (upper) strap member 43.

Thus it is to be appreciated that a barrier system as described herein may advantageously exploit common elevation support elements which may as desired or necessary have a single or common height support member associated with any desired or necessary number of releasable strap engagement members for engaging a plurality of horizontally offset strap members.

Referring to figs. 6 to 12, these figures show, in schematic fashion and by way of example only, various embodiments of barrier systems in accordance with the present invention.

The illustrated example barrier systems are shown as exploiting terminal pillar members (designated a) as terminal anchor elements and intermediate pillar members (designated (3) as intermediate anchor elements. Anchor pillar members (designated a/P) are also shown which serve as a terminal anchor element for one (length of) strap member and also function as an intermediate anchor element for another (length of) strap member.
The pillar members may for example be structural support members of a building or other similar covering structure; the pillar members may thus support and space apart a ceiling structural component from an underlying floor structural component. The ceiling structural component is not shown in the figs 6-12. Furthermore, the upper portions of the pillar members connected to the ceiling structural component are shown as being cut away in figs. 6 to 12.

For the figs. 6 to 12, the tensioning devices for subjecting the various (lengths of the) strap members spanning the distances between the respective terminal anchor elements (i.e. between pillar members which are designated a and/or designated a/(3) are indicated by a common reference numeral, namely 67. The tensioning devices 67 are shown as being on the inner sides of the pillar members, i.e. between the pillar members. A
tensioning device 67 may thus, as shown, be part of a tensioned length of a strap member.
Alternatively, a tensioning device 67 may be disposed so as to be outside the tensioned length i.e. on an opposite or outer side of a terminal pillar member. The tensioning devices 67 for barrier components may of course be the same or different.

Figs. 6 to 12, show elevation support elements which may as illustrated be span support elements, terminal support elements or both; the expression "elevation support element"
may thus sometimes be used below to refer to one or all of such support elements.

In particular figs. 6 to12 show span support elements for various (i.e.
tensioned lengths of) strap members. The span support elements are disposed to engage the strap members at any of various (predetermined) points along the tensioned lengths of the strap members; in other words, a span support element is disposed to engage a strap member at a point along the length of the strap member spanning the distance between the terminal anchor elements (i.e. between pillar members which are designated a and/or designated a/ (3).

As shown in figs. 6 to 12 span support elements may be freestanding span support elements, namely span support elements which are not associated with a pillar member i.e. are not attached or immobilized to a pillar member.

Span support elements are also shown in figs 6 to 12 which alternatively are attached span support elements, namely span support elements which are associated with a pillar member functioning as an intermediate pillar member. Such attached span support elements are thus attached or immobilized to a pillar member designated (3 or to a pillar member designated a/(3.

Terminal support elements are also shown in figs 6 to 12 which are also attached support elements, namely terminal support elements which are associated with a pillar member functioning as a terminal pillar member. Such terminal support elements are thus attached or immobilized to a pillar member designated a or to a pillar member designated a/(3.

Thus for figs. 6 to 12 as may be understood from the above:
a) Span support elements, which are freestanding and thus not attached or immobilized to a pillar member, are commonly designated with the reference numera169;

b) Span support elements which are attached or immobilized to an intermediate pillar member 0, are commonly designated with the reference numera171;

c) Terminal support elements which are attached or immobilized to a terminal pillar member designated a, are commonly designated with the reference numeral 73; and d) Elevation support elements which function both as a span support element and a terminal support element, and which are attached or immobilized to a pillar member a/ (3 are commonly designated with the reference numeral 75.

In accordance with the present invention although the elevation support elements (whether freestanding or immobilized) are for illustration purposes given the above respective common designations for figs 6 to 12, it is to be understood herein that the elevation support elements whether functioning as span support elements, terminal support elements or both, may each independently have the same or different configurations. Thus each of the span support elements, each of the terminal support elements, etc. as shown in figs. 6 to12 may in particular, for example, have a configuration which may be independently selected from among those such as shall be described below by way of example in relation to figures 13 to 53.

In the figs. 6 to12 the elevation support elements whether functioning as span support elements, terminal support elements or both, and comprising a height support member (commonly designated by the reference numeral 76) may have a releasable top-rail strap engagement member (commonly designated with the reference numera177) for releasably engaging a top-rail strap member commonly designated by the reference numeral78.

On the other hand, as the case may be, the elevation support elements whether functioning as span support elements, terminal support elements or both, and comprising a common height support member (commonly designated by the reference numera179) may also have a releasable toe-rail strap engagement member (commonly designated with the reference numeral 80) for releasably engaging a toe-rail strap member commonly designated by the reference numeral 82;
and/or a releasable mid-rail strap engagement member (commonly designated with the reference numeral 84) for releasably engaging a mid-rail strap member commonly designated by the reference numeral 86.

With reference to figs. 6 to 12, a top-rail strap engagement member 77 is connected or attached to the height support member or common height support member for maintaining a respective length of tensioned strap member at a top predetermined height level indicated by the double headed arrow commonly designated by the reference numeral 88.

With reference to figs. 10 and 11 a toe-rail strap engagement member 80 is connected or attached to the common height support members for maintaining a respective length of tensioned toe-rail strap member at a low predetermined height level indicated by the double headed arrow commonly designated by the reference numera190.

With reference to fig. 12 a mid-rail strap engagement member 84 is connected or attached to the common height support members for maintaining a respective length of tensioned mid-rail strap member 86 at a middle predetermined height level indicated by the double headed arrow commonly designated by the reference numeral 92.

As mentioned, as shown in figs 6 to 12, the elevation support elements (whether as a freestanding or immobilized), each comprise a respective height support member. In each case, the height support member 76 or the common height support member 79 has a ground engagement element which in the embodiments shown is simply able to sit on or abut the floor 2 (e.g. is not fixed to the floor).

In figs 6, and 8 tol2 the various lengths of the tensioned strap members is attached to a respective terminal pillar designated a or designated a/(3 by exploiting a girdle element disposed about the pillar member; the girdle elements are commonly identified in these figures by the reference numeral 94. The girdle elements 94 may be the same or different as desired or necessary. The girdle elements 94 may for example comprise a strap anchor segment and be attached to a respective strap member by a respective strap attachment element. Various examples of girdle elements and strap attachment techniques are described below.

In figs. 7, 8, 10, 11 and 12, immobilized elevation support elements (including terminal support elements) may be immobilized to respective pillar members designated a, designated 0 or designated a/ 0 by respective strap/ratchet type elements having strap members which may be tensioned about the pillar members using known ratchet techniques; the strap/ratchet type elements are commonly identified in these figures by the reference numeral 96. The strap/ratchet type elements 96 may be the same or different as desired or necessary. An example strap/ratchet element is described below.

Referring to fig 6, the illustrated barrier system has two terminal pillar members a. The strap member 78 tensioned between these two pillar members by the tensioning device 67 has a tensioned strap member length which is indicated by the parenthesis designated by reference numeral 100. Although the barrier system is shown with a single span support element 69 such a barrier system may have two or more of such span support elements;
an additional span support element is shown in dotted outline. The span support element 69 may for example be centrally disposed between the pillar members a. If two such span support elements are exploited they may be disposed as desired or necessary along the span of tensioned strap member (e.g. they may be equidistantly spaced from a respective pillar member a).

Referring to fig. 7, the illustrated barrier system has two intermediate pillar members (3.
The parenthesis (designated by reference numeral 102) as well as the strap member 78 has terminal dotted lines to indicate that the illustrated barrier system may comprise additional intermediate pillar members 0 along with associated elevation support elements. The terminal dotted lines of the parenthesis 102 and strap member 78 are also to be understood as being indicative that while the terminal anchor elements may take the form of pillar members, the terminal anchor elements may alternatively take any other desired or necessary form provided that the strap member 78 is attached thereto by suitable connector means. As may be appreciated the strap member 78 is tensioned between two terminal anchor elements (not shown) by a tensioning device 67 indicated in dotted outline such that the strap member 78 has a tensioned strap member length which is indicated by the above mentioned parenthesis 102.

Figure 8 illustrates a barrier system which is a combination of the systems shown in figures 6 and 7. Thus in fig 8, the illustrated barrier system has two terminal pillar members a and two intermediate pillar members 0. The strap member 78 which is tensioned between the two pillar members a by the tensioning device 67 has a tensioned strap member length which is indicated by the parenthesis designated by reference numeral 104. The barrier system is shown with a single span support element 69 disposed between pillar members; as may be appreciated such a barrier system may have additional span support elements disposed between pillar members. Furthermore as desired or necessary the barrier system may also include one or more elevation support elements disposed just adjacent the pillar members a as shown in dotted outline; these additional adjacent elevation support elements may be so disposed so as to maintain strap member adjacent the pillar members a at the above mentioned top predetermined height level 88 .

As an alternative to disposing elevation support elements just adjacent the pillar members a as shown in dotted outline in fig. 8, the terminal pillar members a may be associated with respective terminal support elements which are immobilized thereto as shown in figure 9 by respective girdle elements 94. As in the case of figure 6, the strap member tensioned between these two pillar members a by the tensioning device 67 has a tensioned strap member length which is indicated by the parenthesis designated by reference numeral 106.

Fig. 10 shows a modified version of the barrier system indicated in fig. 9.
The illustrated modified barrier system of fig. 10 has two barrier components one of which has the top-rail strap member 78 while the other has a toe-rail strap member 82. The illustrated barrier components however, share the same elevation support elements designated 69 and 73 which have a common height support member 79 for maintaining the top-rail strap member and the toe-rail strap member at respective predetermined height levels 88 and 90; as may be seen in the case of the toe-rail strap member, the second height level 90 is such that this strap member 82 is disposed adjacent the floor 2. An optional additional span support element is also shown in dotted outline. The strap members 78 and 82 which are each tensioned between the two pillar members a by respective tensioning devices 67, each have a tensioned strap member length which is indicated by the parenthesis designated by reference numeral 108.

Referring to Fig. 12, this figure illustrates a modified version of the barrier system indicated in figure 10. Thus in fig 12, the illustrated barrier system has two terminal pillar members a and two intermediate pillar members P. The illustrated modified barrier system of fig. 12 also has three barrier components one of which has the top-rail strap member 78, another of which has the toe-rail strap member 82 and the remaining of which has a mid-rail strap member 86. The illustrated barrier components however, share the same elevation support elements designated 69, 71 and 73 which have a common height support member 79 for maintaining the top-rail strap member 78, the toe-rail strap member 82 and the mid-rail strap member 86 at respective predetermined height levels 88, 90 and 92. Optional additional shared elevation support member(s) are also shown in dotted outline. The strap members 78, 82 and 86 which are tensioned between the two pillar members a by the respective tensioning devices 67, each have a tensioned strap member length which is indicated by the same parenthesis designated by reference numeral 110.

Referring now to fig. 11, this figure illustrates a modified version of the barrier system shown in fig. 12. The barrier system of figure 11 differs from the system shown in figure 12 in that the barrier system of fig. 11 does not exploit strap/ratchet type elements 96 to immobilize the elevation support elements 73 to the terminal pillar members;
the elevation support elements 73 are immobilized by the girdle elements 94 alone.
The barrier system of figure 11 also differs from the system shown in figure 12 in that the barrier system of fig. 11 only has a top-rail structure and a toe-rail structure. The barrier system of figure 11 additionally differs from the system shown in figure 12 in that there are four barrier components each of which comprises a respective tensioned strap member length. In other words, there are four tensioned strap member lengths.
The top rail structure is thus defined by the two (upper) tensioned strap member lengths designated by the two parenthesis indicated by reference numerals 112 and 114.
The toe rail structure is defined by the two (underlying) tensioned strap member lengths designated by the tow parenthesis indicated by reference numerals 116 and 118.
The illustrated barrier components, furthermore, share the same elevation support elements designated 69, 73 and 75 which have a common height support member 79 for maintaining the top-rail strap members 78 and the toe-rail strap members 82 at respective predetermined height levels 88 and 90. .

Referring to figs. 13 to 53, these figures illustrate various example embodiments of elevation support elements which may be used as an elevation support element having a common height support member. Thus the illustrated elevation support elements each have a respective common height support member (which for illustration purposed herein is designated by the same reference numeral 120. The common height support members 120 each includes a respective ground engagement element (which for illustration purposes herein is designated by the same reference numeral 122).

In the figs. 13 to 53 three respective releasable strap engagement members are attached to a respective common height support member 120. Thus in the figs. 13 to 53 for illustration purposes releasable top-rail strap engagement members are commonly designated by the reference numeral 124; releasable mid-rail strap engagement members are commonly designated by the reference numeral 126; and releasable toe-rail strap engagement members are commonly designated by the reference numeral 128. These releasable strap engagement members are each attached to, connected to, or part of a respective common height support member 120 for releasably engaging a respective top-rail, mid-rail and toe-rail strap member (commonly designated in these figs by the reference numerals 130, 132 and 134). These rail strap members 130, 132 and 134 are to be understood as being un-tensioned unless they are shown is association with opposed arrows indicative of tensioning thereof.

In accordance with the present invention a releasable strap engagement member for a elevation support element may take any desired or necessary form keeping in mind the function thereof. As mentioned above, the present invention may be exploited by having recourse to a releasable strap engagement member for the elevation support element which may, for example, take the form of a clamp structure.

Figs. 13 to 20 illustrate elevation support elements having a clamp type structure which is essentially the same for all three respective releasable strap engagement members 124, 126 and 128. Figs. 13 and 17 show the same type of elevation support elements except that the elevation support element of figs. 13 and 14 differs from that of fig. 15 in that the elevation support element of figs 13 and 14 is additionally associated with a padlock mechanism described below.

Referring in particular to figs. 16 and 17, each of the illustrated releasable clamp structures comprises a first clamp member 140 and a second clamp member 142;
the second clamp member 142, as may be seen, is defined by a portion of the structure of the common height support member 120 which is juxtaposed with the first clamp member 140. The first clamp member 140 is connected to the height support structure by a connector element and by an adjustable locking element.

The connector element comprises a bolt member 144 and a mating nut member 145 The stem 146 of the bolt member 144 is able to pass through aligned openings 147 and 148 so that the threaded end 149 of the bolt member 144 is seated into the interior thread of the nut member 145 just enough to provide for a default clearance 150 (i.e. a clearance space) between the first and second clamp members. The default clearance 150 is at least sufficient to allow a (tensioned) rail strap member to pass between the first and second clamp members when the adjustable locking element is in a loosened state, i.e.
for disposition of a strap member in and out of the space defined by the default clearance 150. The connector element is present to maintain this minimum connection between the first and second clamp members 140 and 142.

The adjustable locking element comprises an eye bolt member 154 and a nut like rivet member 158 which is machine pressed (in any known manner) to the height support member 120. The eye bolt member 154 has a threaded end 160 for screw engagement with the interior thread of the nut like member 158. The eye bolt member154 also has a stopper member 162 which is fixed to its stem just rearward of the threaded end 160 so that the threaded end 160 is exposed. The exposed threaded end 160 is sized to pass through an opening 164 (in the first clamp member 140) which is aligned with the opening 166 of the threaded interior of the nut like member 158 so that the threaded end 160 can screw engage the threaded interior of the nut like member 158.

As may be appreciated the exposed threaded end 160 of eye bolt member154 and the interior thread of the nut like member 158 are configured such that rotation of the threaded end 160 of the eye bolt into the nut like member (i.e. in a tightening rotational direction) will induce or cause the stopper member162 to bear down on the first clamp member 140. As the stopper member 162 bears down on the first clamp member 140, the first clamp member 140 is urged (i.e. is displaced) towards the second clamp member 142 which in turn reduces the clearance between the first and second clamp members relative to the mentioned default clearance 150. If a rail strap member is disposed between the first and second members it will eventually be squeezed or clamped between these two clamp members. A rail strap member so clamped may be released by rotation of the threaded end 160 of the eye bolt out of the nut like member 158 so that the above mentioned default clearance 150 is obtained.

In more general terms the first clamp member is displaceable relative to the second clamp member by (eye bolt) adjustment means configured for facilitating displacement of the first and second clamp members relative to each other for engagement and disengagement of a strap member there between.

If desired, a releasable strap engagement member 124 may be provided with suitable means for locking the two clamp members 140 and 142 together in place. As may be seen in figs. 13, 14 and 17 such a locking mechanism, may comprise openings 170 and 172 (see fig. 17) which are suitably provided in the first clamp member140 and the second clamp member 142 respectively. As may be seen from figs. 13 and 14 the openings 170 and 172 may be configured to receive the U-shaped shackle 174 of a padlock mechanism for locking the first and second clamp members together.
This type of locking mechanism may provide an extra security feature in that the tensioned strap member may, for example, not be undesirably tampered with i.e. disengaged from the clamp member. The padlock mechanism is of course installed once the releasable strap engagement member 124 engages a strap member.

Turning to figs. 18 and 19 these figure illustrate the engagement of an elevation support element of figs 13 to 17 with a tensioned top-rail strap member, a tensioned mid-rail strap member and a tensioned toe-rail strap member. In particular fig. 18 shows in general the process for engagement of the clamp type elevation support element of figs. 13 to 17 into engagement with the three tensioned strap members 130, 132 and 134. For such engagement it is of course understood that the clamp structures are disposed so as to provide the default clearance 150 for insertion of the rail strap members between the first and second clamp members. The tensioned rail strap members 130, 132 and 134 are inserted into respective clearance spaces 150 by positioning the elevation support element 120 as shown at an angle to the vertical. Once the strap members are manipulated into a respect clearance space 150 the elevation support element 120 is rotated to the vertical position shown in fig. 19. The adjustable locking element is then manipulated to clamp the strap members between respective clamp members. If desired or necessary an above mentioned padlock mechanism may then be added; see shown in fig. 20. For removal of the elevation support element the reverse process is followed.

Alternatively, as mentioned above, a releasable strap engagement member may comprise grip means which generally comprises a loop element.

Figs.21 to 27 show example embodiments of elevation support elements exploiting grip means comprising loop elements for the top, mid and toe releasable strap engagement members. Figs. 21 to 25 show the same type of elevation support elements except that the elevation support element of figs. 21 and 22 differs from that in figs. 24 and 25 in that the elevation support element of fig. 21 and 22 is additionally associated with a padlock mechanism described below.

Referring to figs. 24 and 25 as may be seen each of the exemplified grip means for the releasable strap engagement members 124, 126 and 128 comprises a respective loop element 180, 182 or 184 in the form a U-shaped member. The loop elements 180, and 184 each have a respective aperture 186, 188 or 190 for (longitudinally) receiving a respective rail strap member 130, 132 or 134. Each (U-shaped) loop element is also split by a respective straight lateral strap opening 192, 194 or 196 (i.e. open mouth) for lateral displacement of a (e.g. un-tensioned) strap member into and out of the aperture 186, 188 or 190 defined by the loop element. Referring to figs. 26 and 27 the (tensioned) rail strap members 130, 132 or 134 are shown longitudinally disposed and longitudinally seated in a respective aperture of a respective loop element.

Referring back to fig. 25, this figure is illustrative of the steps to longitudinally seat the rail strap members 130, 132 and 134 in respective apertures 186, 188 and 190.
For example the un-tensioned toe-rail strap member 134 may be seated first, followed by seating of the un-tensioned op-rail strap member 130 and the un-tensioned mid-rail strap member 132, In particular, for seating of the toe-rail strap member 134, the height support member 120 is vertically disposed as shown in fig. 25 so that the open mouth 196 of the respective (U-shaped) loop element is disposed so as to face downwardly. The (un-tensioned) toe-rail strap member 134 is then manipulated thru the respective open mouth 196 so as to be disposed in the respective aperture 190 and thereafter the open mouth 196 is disposed adjacent the underlying support structure, i.e. the open mouth 196 is thus (essentially) closed or blocked off by the floor 2.

On the other hand, with the height support member 120 being vertically disposed as shown in fig. 25, the respective open mouths 192 and 194 of the (U-shaped) loop elements are disposed so as to face upwardly for receiving respectively the (un-tensioned) top-rail strap member 130 and the (un-tensioned) mid-rail strap member 132. At this point, the respective (un-tensioned) strap members 130 and 132 are manipulated thru the respective open mouths 192 and 195 so as to be disposed in the respective apertures 186 and 188.

Once each strap member 130, 132 and 134 is seated in a respective aperture 186, 188 and 190 the strap members are each tensioned in place (see fig. 26). For removal of the elevation support element the reverse process is followed.

As may be appreciated once the rail strap members 130, 132 and 134 are tensioned in a respective aperture 186, 188 or 190, each respective grip means may rely on the (horizontal) tension of the strap members to maintain the strap members in the respective aperture of the respective loop element. However, if desired, the elevated support element may (as shown in fig. 26) be associated with a padlock type mechanism for closing off the mouth 192 of the uppermost (U-shaped) loop element during use, i.e. in a manner analogous to that as discussed above with respect to figs. 14 and 20).
Fig. 27 illustrates the elevation support element in place with no padlock mechanism.

As an alternative approach, a grip means may generally comprise a loop element which is split by a convoluted lateral strap opening (i.e. convoluted passageway) which provides for lateral access to the aperture of the loop element. For this type of example grip means, the loop element and associated convoluted strap opening are configured such that lateral displacement of a tensioned rail strap member out of the aperture thru the convoluted lateral strap opening is further inhibited by the disposition and configuration of the convoluted strap opening. The loop element and the convoluted strap opening are, however, configured for sideways (manual) threading of an un-tensioned rail strap member through the convoluted strap opening into and out of aperture of the loop element. Example embodiments of this type of grip means are shown in figs. 28 to 31.

Turning to figs. 28 to 31, these figures show an elevation support element exploiting the above mentioned type of constricted strap opening structure in relation to the top, mid and toe releasable strap engagement members 124, 126 and 128. Thus for the illustrated example elevation support element, the loop elements 202, 204 and 206 are each defined by respective pairs of spaced apart (i.e. offset) mirrored L-shaped brackets.
A space separating each of the L-shaped brackets (of such pairs of brackets) defines a respective convoluted strap opening 208, 210 and 212 (see fig. 29). The convoluted strap openings 208, 210 and 212 are each configured for sideways threading of a respective (un-tensioned) rail strap member through such convoluted strap opening into and out of the aperture of the respective loop elements 202, 204 and 206. In other words, for this type of grip means, a strap member in un-tensioned state is deformed relative to the tensioned state thereof and in the deformed state may be passed into or out of the aperture defined by the loop element. The convoluted opening strap openings 208, 210 and 212 are however, configured such that when a strap member is in a tensioned state, the convoluted nature of the convoluted strap opening contributes to the inhibition of lateral or sideways displacement of a rail strap member out of the aperture of a respective loop element. Figure 30 shows un-tensioned rail strap members 130, 132 and 134 being threaded sideways (i.e. laterally) through the convoluted opening into the aperture of the loop elements. Fig. 31 shows the rail strap members 130, 132 and 134 in a tensioned state longitudinally seated in the aperture defined by respective L-shaped brackets. For removal of the elevation support element the reverse process is followed.
In accordance with the present invention, an aperture defined by a loop element of a grip means may, for example, take a more slot like form. The loop element may be split by a strap opening for providing access to and from the slot like aperture which may also be slot like. Such slot like strap opening may be straight or it may be convoluted as desired or necessary. The height support member for these types of elevation support elements may have a T-like cross-section.

Figs 32 to 36 illustrate an alternate structure for an elevation support element which exploits a straight slot like lateral strap opening technique in relation to the top and mid releasable strap engagement members 124 and 126. As may be seen the loop element for each of the releasable strap engagement members 124, 126 and 128 defines a respective elongated slot aperture 220, 222 or 224. The top and mid elongated slot apertures 220 and 222 are each split by a respective straight inclined slot opening 226 or 228 for communication with the (interior of a) respective elongated slot aperture. On the other hand, in the case of the toe releasable strap engagement member 242, the grip means comprises a (U- shaped) loop element defining the elongated slot aperture 224 but wherein the mouth 229 thereof is disposed so as to face downwardly such that the mouth 229 is adjacent the underlying support structure, i.e. when the toe-rail strap member 134, is under (horizontal) tension, the underlying support structure essentially blocks or closes off the mouth 229 (see fig. 35).

If desired or necessary a padlock mechanism 230 (having a structure as described above) may be exploited; see fig. 32.

The height support member 120 of figs. 32 to 35 may be provided with web openings 232 and 234 for receiving the web of a pillar attachment mechanism such as shall be described below.

Turning to fig. 34, this figure illustrates the engagement of an elevation support element of fig. 33 (or 32) with an un-tensioned top-rail strap member 130, an un-tensioned mid-rail strap member 132 and an un-tensioned toe-rail strap member 134. In particular fig.
34 shows in general the sideways threading process for engagement of the elevation support element of fig. 33 into engagement with the three un-tensioned rail strap members 130, 132 and 134. For such engagement it is of course understood that the un-tensioned strap members 130, 132 and 134are manipulated (i.e. inserted) into respective elongated slot apertures 220, 222 or 224 either via an inclined slot opening 226 or 228 or via the mouth 229. Once the rail strap members are manipulated into respective elongated slot apertures and the elevation support element is vertically disposed the rail strap members 130, 132 and 134 are tensioned as seen in fig. 35. As shown in figure 36, an above mentioned padlock mechanism 230 may as desired also be exploited. For removal of the elevation support element the reverse process is followed.

Figs 37 to 40 illustrate an alternate structure for an elevation support element which exploits a convoluted slot like lateral strap opening technique in relation to top and mid releasable strap engagement members.

Apart from the convoluted slot openings, the elevation support element of figs. 37 to 40 has a structure analogous to the structure as shown in above figures 32 to 36.
Thus as may be seen the loop element for each of the releasable strap engagement members 124, 126 and 128 defines a respective elongated slot aperture 240, 242 or 244. The top and mid elongated slot apertures 240 and 242 are each split by a respective contorted slot opening 246 or 248 for communication with the (interior of a) respective elongated slot aperture. On the other hand, in the case of the toe releasable strap engagement member 128, the grip means comprises a (U- shaped) loop element defining the elongated slot aperture 244 but wherein the mouth 250 thereof is disposed so as to face downwardly such that the mouth 250 is adjacent the underlying support structure, i.e.
when the toe-rail strap member 134, is under (horizontal) tension, the underlying support structure (i.e.
floor 2) essentially closes or blocks off the mouth 250 (see fig. 35).

The height support member may be provided with web openings 260 and 262 for receiving the web of a pillar attachment mechanism such as shall be described below.
Turning to fig. 39, this figure illustrates the engagement of an elevation support element illustrated in figs. 38 and 39 with an un-tensioned top-rail strap member 130, an un-tensioned mid-rail strap member 132 and an un-tensioned toe-rail strap member 134. In particular fig. 39 shows in general the sideways threading process for engagement of the elevation support element of figs. 38 and 39 into engagement with the three un-tensioned rail strap members 130, 132 and 134. For such engagement it is of course understood that the un-tensioned strap members 130, 132 and 134 are manipulated (i.e.
inserted) into respective elongated slot apertures 240, 242 or 244 either via a convoluted slot opening 246 or 248 or via the mouth 250. Once the rail strap members are manipulated into respective elongated slot apertures and the elevation support element is vertically disposed the rail strap members 130, 132 and 134 are tensioned as seen in fig.
40. For removal of the elevation support element the reverse process is followed.

In accordance with the present invention a further alternative mechanism for a releasable strap engagement member may comprise grip means which has a loop element which defines a rail aperture for receiving a strap member and wherein the rail aperture may be accessed by a closeable lateral strap opening. Thus for this type of grip means, a loop element may be provide which may be (actively) split by a strap opening structure dimensioned/configured for passage of a rail strap member through the (closable) strap opening into and out of said aperture. In accordance with such further alternative structure, the grip means may comprise a closure means displaceable between an open position and a closed position. The loop element and the closure means may thus be configured for inhibiting displacement of the strap member out of the aid aperture thru the strap opening when the closure means is in said closed position, and be configured such that when said closure means is in said open position, the strap opening may be unobstructed by the closure means with respect to passage of the strap member thru the strap opening. In accordance with such further alternative structure, the grip means may be a slider type grip means. Such slider type grip means may comprise such closure means which is displaceable between an open position and a closed position.
Figs 41 to 49 illustrate the slider type structure for an elevation support element which exploits grip means having a closure means displaceable between an open position and a closed position in relation to the top and mid releasable strap engagement members 124 and 126. Figs 41 and 42 show respectively the open and closed configuration of this alternative embodiment. As may be seen from fig. 41, which shows an open configuration, the upper loop elements for the top and mid strap engagement members 124 and 126, are split by a respective strap opening 268 or 270. The strap openings 268 and 270 provide for rail strap member communication with the thus opened elongated slot aperture 272 or 274 as the case may be. However, referring to fig 42, which shows a closed configuration, the loop elements for the top and mid releasable strap engagement members 124 and 126 are in a closed elongated slot aperture configuration. On the other hand, in the case of the toe releasable strap engagement member 128 the grip means comprises a (U- shaped) loop element also defining an elongated aperture 276 but wherein the mouth 280 is disposed so as to face downwardly such that the mouth 280 is adjacent the underlying support structure, i.e. when a toe rail strap member, is under (horizontal) tension, the underlying support structure (i.e. floor 2) essentially blocks or closes off the mouth 280.

If desired or necessary an above mentioned padlock mechanism (e.g. see fig.
22) may be exploited; see figs. 47 to 49 which apart from the padlock mechanism illustrate the same elevation support element as shown in figs. 41 to 46 The elevation support element of figs. 47 and 48 have openings for receiving a padlock shackle.

Turning to fig. 43, this figure shows, in exploded view, the general structure of the exemplified elevation support element of figures 41 and 42. As may be seen the elevation support element is composed of three main members, namely two outer post members 290 and an inner slider member 292.

The two outer post members 290 each have the same structure which is similar to that of the elevation support element which is shown in side view if figure 24. Thus, as may be seen from fig. 43, each outer member 290, defines, for each of the top, mid and toe releasable strap engagement members 124, 126 and 128, an outer loop component which comprises a U-shaped member. The U-shaped members define respective elongated slots 292, 294 and 296.
The U-shaped members 290 of the outer post members for the top-rail strap member 130 and the mid-rail strap member 132 each have an open mouth 298 which is disposed so as to face upwardly. On the other hand, in the case of the toe-rail strap member 134, the mouth 300 of the lowest U- shaped member of each of the outer post members 290 is disposed so as to face downwardly. In other words, the mouth 300 of the lowest U-shaped member is to be disposed adjacent the underlying support structure, i.e. when a strap member, is under (horizontal) tension, the underlying support structure (i.e. floor 2) essentially close or blocks off the mouth 300 of this lowest U-shaped member.
The lowest U-shaped member thus has a structure similar to that for the elevation support element of figure 24.

The inner slider member 292 is configured and attached to slide up and down between the two outer post members 290. For this purpose, each of the outer post members 290 is provided with three attachment openings 304. These openings 304 are able to be aligned with an opposed corresponding attachment opening 304 of the other post member 290. On the other hand, the inner slider member 292 is provided with three equal length longitudinally extending (linear) motion travel slots 305 which may each be aligned with a respective pair of opposed attachment openings 304 of the outer post members 290.
The (threaded) stem of each bolt member 308 is able to pass through a pair of aligned attachment openings 304 as well as an intermediate respective aligned linear motion slot 305 such that the threaded end portion of the bolt stem may engage with a respective nut 309 for holding the outer post members 290 and the slider member 292 together as an assembly when the assembly is in either a closed or an open configuration (see figs 41 and 42). Furthermore, the engagement between the threaded stem of at least one such bolt 308 and its respective (locking) nut 309 is such that such nut 309 may be tightened onto the bolt stem so as to induce the nut 309 and bolt 308 to clamp (i.e.
lock) the outer post members 290 to the slider member 292 for maintaining the slider member 292 in a predetermined position; additionally such nut 309 may be loosened to release such clamping action so as to allow the slider member 292 to be displaced (i.e.
slide) between an open position and a closed position (see figs 41 and 42).
More generally, the assembled stems of bolts 308 and the motion slots 305 are so disposed such that the slider member 292 may be displaced longitudinally up and down within the limits of motion dictated by the length of at least one such motion slot 305, i.e.
when a locking nut 305 is in a loosened state. In conjunction with the motion slots 305, the inner slider member 292 is sized such that the lower end thereof will not impinge upon a toe rail strap member when the assembly is in a closed configuration.

Still referring to fig. 43 with respect to the open configuration of the assembly, the inner slider member 290 is also provided with an upper and a mid U-shaped member having respective elongated slots 312 and 314 provided with respective mouths 316 and which are each disposed so as to face downwardly.

Referring back to figs. 41 and 42, it is thus to be appreciated that in accordance with the illustrated embodiment the outer post members 290 and the inner slider member 292 are configured and interconnected such that the inner slider member 292 is linearly displaceable relative to the outer post members 290 between a strap lock-in position (i.e.
closed configuration) and a strap release position (i.e. open configuration).
Fig. 42 shows a strap lock-in position while fig. 41 shows a strap release position.

Referring to fig.41 when the slider member 292 is in the illustrated strap release position, the outer post members 290 and the inner slider member 292 define two upper opened loop elements, the opened loop elements each defining a respective strap aperture 272 and 274 which is split by a respective strap opening 268 and 272. The strap openings 268 and 272 are dimensioned/configured for passage of a rail strap member through such strap opening into and out of the respective strap aperture. Figs. 44 and 45 show the process of engagement of the (open configuration) elevation support element to tensioned rail strap members 130, 132 and 134; the engagement process is similar to the process for the clamp structure as seen aboOve (i.e. see fig. 18). The toe rail strap engagement member of the embodiment shown engages the toe rail member the same as for the elevation support element of fig 40.
Referring to fig. 42, when the slider member 292 is in the strap lock-in position, the outer post members 290 and the inner slider member 292 define closed loop elements, the closed loop elements defining the (closed) slot apertures 272 and 274 for engaging the respective rail strap members, the closed loop elements being configured for inhibiting sideways (radial) (i.e. lateral and vertical) displacement of a respective rail strap member out of a (closed) slot aperture 272 or 274. Fig. 46 shows the engagement of the elevation support element to tensioned strap members, the top and mid rail strap engagement members 124 and 126 being in the strap lock-in configuration therefore. The toe rail strap engagement member 128 of the embodiment shown still engages the toe rail member the same as for the elevation support element of fig 40.

Figs. 47 to 49 show the same height elevation support element as illustrated in previos fis 41 to 46 but which are also provided with shackle openings 320 and 321 to receive the shackle 325 of a padlock mechanism.

Referring to figures 50 to 53 these figs illustrate another example elevation support element wherein the releasable strap engagement members comprises grip means which take the same general form as the grip means of the elevation support elements as illustrated in fig. 24. Thus, the grip various means comprise loop elements 330, 332 and 334 in the form of U-shaped members. The loop elements 330, 332 and 334 each have an elongated aperture 336, 338 or 340 for (longitudinally) receiving a respective rail strap member. Each (U-shaped) loop element is also split by a respective straight lateral strap opening (i.e. open mouth) for lateral displacement of a (e.g. un-tensioned) rail strap member into and out of the elongated aperture 336, 338 or 340 defined by the loop element. The open mouth of such U-shaped member for the top-rail strap member and the mid-rail strap member is disposed so as to face upwardly when a rail strap member is disposed in the aperture thereof.

However, the illustrated grip means for the top-rail strap member and the mid-rail strap member further comprises a respective stopper member 350 or 352 and a respective spring biased lock swing arm 354 or 356. Each stopper member is mounted on one side of a respective open mouth while a respective spring biased lock swing arm is pivotally mounted to the other side of the respective open mouth.

Referring to figs. 52 and 53, the lock swing arms 354 and 356 are each able to pivot into a respective aperture 336 or 338 but are prevented from pivoting out of such apertures by the stopper member 350 or 352. For this example embodiment the lock swing arms and 356 are spring biased (in any suitable way) in a respective position wherein they each respectively abut a respective stopper member350 or 352 The lock swing arms 354 and 356 are each biased in a position wherein it closes off a respective open mouth (see fig. 53). The lock swing arms may however be urged (see fig. 52) to pivot to a position within a respective aperture wherein it no longer blocks off the respective open mouth. In other words, a lock swing arm is disposed for pivotal displacement between an open position within the respective aperture wherein the open mouth is unobstructed and a closed position wherein the lock swing arm abuts the stopper member and obstructs the respective open mouth. Thus a loop element, respective stopper member and respective lock swing arm are configured for inhibiting displacement of a rail strap member out of the respective aperture thru the strap opening (i.e. open mouth) when the lock swing arm is in the closed position, and are also configured such that when the lock swing arm is in the open position, the strap opening (i.e. open mouth) is unobstructed by the swing arm with respect to passage of the strap member thru the strap opening.

Referring to fig. 52, this figure shows the basic step for seating a rail strap member in the grip means aperture, namely by the pressing downward of the lock swing arm to slip the strap member into the aperture. Once the strap member is seated in the aperture, the lock swing arm is biased back to the closed position (see fig. 53 ) wherein the lock swing arm will impede lateral displacement of the strap member out of the aperture.
For the removal of the strap member the lock swing arm is first biased downwardly to free up the open mouth and the strap member is thereafter removed.
As mentioned above, each of the anchor attachment members may comprise a respective strap anchor segment for defining a girdle element for disposition about a(terminal) pillar member. Each of the anchor attachment members may further comprise a strap attachment element for attaching the girdle element to a strap member.

Turning to figs. 54 to 73, these figures illustrate various example embodiments of anchor attachment members for attachment of illustrated example strap members to (in situ) pillar type anchor elements. The embodiments have common features which are designated by common reference numerals.

Figs. 54 and 59 illustrate example strap member embodiments. The strap member embodiments shown in Figs. 54 and 59 each have two separate band parts, namely, band parts 365 and 366. As seen, the strap members also include a tensioning or ratchet device 367 able to interconnect the band parts 365 and 366. As may be understood the band part 366 is fixed at one end to the tensioning device 367 in any suitable way whereas the other band part 365 has an end which is able to be releasably fed into the ratchet mechanism of the tensioning device 367 so at to allow thereby the tensioning and un-tensioning of the strap member.

For the strap member embodiments shown in figs. 54 and 59, opposite ends of each of the illustrated example strap members include a strap anchor segment which is exploitable as part of the anchor attachment members which define the girdle elements for disposition about terminal (anchor) pillar members.

Referring to fig. 54 opposite ends of the illustrated strap member are provided with a respective carabiner type connector (i.e. a hook connector having spring gate member and which has a releasable connectivity structure analogous to that of the gated structure of the elevated support element shown in fig. 52). The carabiner type connectors are herein generally designated with the common reference numera1370. The carabiner type connectors 370 may be releasably connected (in known fashion) to ring connector elements 375 which are also provided to act as strap attachment elements.

As seen in fig. 55 a respective carabiner type connector 370 may be connected to a respective ring connector element 375 to form a girdle element 380 for disposition about a respective (terminal) pillar member. As may also be surmised, the illustrated strap member is connected to a terminal pillar member by pulling the carabiner type connector 370 around a terminal pillar member until it is able to quick connect (i.e.
hook) to the respective ring connector element 375 . With both ends of the strap member so connected to respective terminal pillar members the strap member may then be (releasably) tensioned in place by the tensioning device 367. A barrier system comprising the illustrated strap member may be dismantled by, inter alia, releasing the tension on the strap member and then decoupling the carabiner type connectors 370.
Example barrier systems exploiting the strap member illustrated in figs. 54 and 55 are illustrated in figs. 56 and 57.

Fig. 56 shows an example barrier system which exploits an elevation support element commonly designated hereinafter by the reference numeral 382; elevation support element 382 has the structure of the elevation support element as illustrated in fig. 13.
Fig. 56 also shows the girdle attachment of the strap member illustrated in figs. 54 and 55 to terminal pillar members using girdle elements 380 as seen in fig. 55.

Fig. 57 shows a modified barrier system similar to that shown in fig. 56 except that the barrier system exploits three elevation support elements commonly designated by the reference numeral 384; an elevation support element 384 has the structure of the elevation support element as illustrated in fig. 32. Two of the elevation support elements 382 shown in fig. 57 are immobilized to a respective terminal pillar member by a pair of respective tensionable ring connectors; these tensionable ring connectors are herein generally designated with the common reference numera1386.

Fig. 58 is an enlarged view of a tensionable ring connector 386. As may be seen in fig.
58 a tensionable connector ring 386 comprises a web element 390 one end 392 of which is fixed to a tensioning or ratchet device 394 and the other end of which may be (removeably) fed to or removed from the tensioning device 394 (in known manner). For the immobilization of an elevation support elements 384 to the terminal pillar members the free end of respective webs 390 is first fed through respective web opening g 232 and 234 of the respective elevation sup[port element 384 before being fed to the respective tensioning device 394. Thereafter each web 390 is tensioned to immobilize a respective elevation support element 384 to a respective terminal pillar member. The tensioning device 394 may have a configuration the same as or similar to the ratchet device used to tension a strap member as seen in fig. 54 and 55.

Turning to fig. 59 this figure illustrates an alternate strap member and anchor attachment mechanism. As seen, the opposite ends of the illustrated trap member are be provided with respective loops ends 400. As seen in fig. 60 and 61 the looped ends 400 may be looped within themselves in order to form a noose (i.e. a girdle element 402) for disposition about respective terminal pillar members. The illustrated strap member is as mentioned above connected to the tensioning device 367 in two parts, one of which is fixed to the tensioning device (in known manner) and the other releasable part is able to be releaseably fed to or removed from the tensioning device. As may be surmised, each part of the strap member may be looped about itself so as to form the above mentioned girdle element 402 girdle around a respective terminal pillar member. The releasable strap part 365 is then fed (i.e. connected ) to the tensioning device 367 in suitable (i.e.
known) manner. With both ends of the strap member so connected to respective terminal pillar members the strap member may then be tensioned in place. The barrier system may subsequently be dismantled by, inter alia, releasing the tension on the strap member and then decoupling the releasable strap part from the tensioning device followed by removal of the strap member parts from the terminal pillar members..
Fig. 62 shows an example barrier system which exploits the previously mentioned elevation support element 382. Fig. 62 also shows the attachment of the strap member to terminal pillar members using the girdle elements 402 seen in figs. 60 and 61 to The types of anchor attachment members shown in figs 54 to 62 are suitable for a single length of strap member to be attached to respective terminal pillar members.
However, if the single strap member is not long enough and it is desired to cascade or daisy chain two or more strap members using common terminal pillar members(s) a problem arises with respect to maintaining strap height level consistency. The nature of the anchor attachment mechanisms of figs 54 to 62 is such that strap members on opposite sides of a common terminal pillar member would be set at different heights. This may be seen from figs. 63 and 64 where strap members on opposite sides of the terminal pillar members are set at different height levels. As may be seen, if the same type of elevation support elements 384 are to be used then the height support elements on one side of a common terminal pillar member would be too short (as indicated by the arrows 410) and would not be able to touch the ground or floor.

Accordingly for (daisy) chaining strap members to common terminal pillar members, recourse may be had to an example strapping combination as shown in fig. 65, namely a combination which comprises a strap member and at least one anchor attachment member (two being shown). This type of anchor attachment member has the advantage that the (daisy) chained strap members may be independently tensioned or un-tensioned.

As may be seen the strap member has the form as shown in fig. 54 (but without ring connector elements 375). The anchor attachment members each have the form of the tensionable ring connector as shown in fig 58 (but are also provided with two connector rings commonly designated with the reference numera1412) . An anchor attachment member which is illustrated in fig. 66 is essentially the same as the tensionable connector ring as seen in fig. 58, i.e. the anchor attachment members of fig. 66 is releasably tensionable about a pillar member by passing the web 390 thru respective strap member apertures of the elevation support element. The ring connector elements 412 are provided to act as strap attachment elements for attaching respective strap members to the same or common terminal pillar member (i.e. by strap member carbiner type connectors 370).
Thus, as may be appreciated and referring to fig. 65, each of the anchor attachment members comprises a separate strap attachment segment (i.e. web 390 of fig.
66) associated with two attachment ring connectors 412 and a respective tensioning device 394. On the other hand, the example strap member illustrated in fig. 65 is (as mentioned above) provided at both ends with a respective quick clip element (i.e.
carabiner type fasteners 370) for connection to respective ring connectors.

The strap attachment segment 390 may be used to define a girdle element 414 about a respective terminal pillar member. Turning to fig. 67 this fig. illustrates three such girdle elements 414 for connection to respective strap members to define top, mid and toe strap-rails, i.e. a girdle element 414 may be exploited to attach two strap members to a common terminal pillar member on opposites sides of the common terminal pillar member. In fig. 67 the elevation support element is the above mentioned elevation support element 384. The girdle elements 414 are each (releasably) maintained at a predetermined height level by engagement of the web 390 thereof with a respective aperture 220, 222 and 224 of the elevation support element 384 (see fig. 32).

As an optional feature the elevation support element 384 is (also) immobilized to the terminal pillar by a pair of tensionable connector rings illustrated 386 (i.e see fig. 58).

For comparison, fig 68 shows the tensionable connector rings 386 being used to releasably immobilize an elevation support element 384 to an intermediate pillar member; the web 390 passing thru the web attachment openings 232 and 234 (see in particular fig. 32 for the web attachment openings 232 and 234) .

Thus, by exploiting anchor attachment members such as seen in fig. 65 it is possible to (daisy) chain a two or more lengths of strap members using a common terminal pillar while conserving a common height level on either side thereo The anchor attachment member(s) may as shown comprise a connector combination which may for example comprise at least one a ring connector 412. Alternatively, the anchor attachment member may have carabiner type connectors 370 while the ends of the strap member may have ring connectors 375. In any case, the connection of the anchor attachment member to the strap member may be modified in other (suitable) manner keeping in mind the desired result, namely a consistent height on both sides of a terminal pillar member.
Referring back to fig. 57, this figure shows a barrier system in accordance with the present invention with one rail strap member (i.e. top-rail strap member) as shown in fig.
55 and wherein above mentioned girdle elements 380 attach the strap member to terminal pillar members. The anchor attachment members comprise the previously mentioned quick clip connectors (i.e. carabiner type connectors 370) attached at both ends of the strap member and which are in turn hooked up to the previously mentioned ring connectors 375. The barrier system shown exploits the same type of elevation support member 384 as terminal elevation support elements and as a span elevation support element, namely, the elevation support element of figure 32. The terminal elevation support elements 384 are immobilized to both of the terminal pillar members by the strap attachment segment 386. The elevation supports elements 384 immobilized to the terminal pillars are also connected to the girdle elements 380 via apertures 220 (see fig.
32). Although not shown in fig, 57 the girdle elements 380 disposed about one or both of the terminal pillar members may as desired comprise an additional ring connector (for daisy) chaining of another similar strap member to the same terminal pillar.
Such secondary ring connectors are shown in dotted lines in fig. 55.

Figs. 69 to 73 illustrate barrier systems in accordance with the present invention which each have a top strap-rail. The systems exploit three in-situ pillar members, two of which are terminal pillar members and one of which is an intermediate pillar member.
The barrier systems exploit (terminal) elevation support elements 384 (as characterized above) which are immobilized to respective terminal pillar members by tensionable ring connectors 386; the systems also exploit an elevation support element 384 which is immobilized to a respective intermediate pillar member also by tensionable ring connectors 386. The terminal girdle elements 414, however, shown with a single (i.e.
not two) connector rings 412. The barrier systems are shown as exploiting a span (elevation) support element 382 or 384 (both as characterized above). Although the same style of elevation support elements are shown for immobilization to the terminal pillar members, the elevation support elements as shown may take any other form as shown herein. In other words in accordance with the present invention the elevation support elements may take the same or different style as desired or necessary.

Fig. 69 shows a barrier system with a top strap rail only. The system uses the elevation support element (designated previously with the reference numeral) 382 for the span elevation support elements and elevation support element (designated previously with the reference numeral 384) as terminal elevation support elements.

Fig. 70 shows a barrier system with a top and mid strap rail. The system also uses the elevation support element (designated previously with the reference numeral) 382 for the span elevation support elements and elevation support element (designated previously with the reference numeral 384) as terminal elevation support elements.

Fig.71 shows a barrier system with a top and toe strap rail. The system shown also uses the elevation support element (designated previously with the reference numeral) 382 for the span elevation support elements and elevation support element (designated previously with the reference numeral 384) as terminal elevation support elements.

Fig. 72 shows a barrier system with a top, mid and toe strap rail. The system again uses the elevation support element (designated previously with the reference numeral) 382 for the span elevation support elements and elevation support element (designated previously with the reference numeral 384) as terminal elevation support elements.

Fig. 73 shows a barrier system with a top, mid and toe strap rail such as illustrated in prior fig. 72 but which exploits a single type of elevation support element as both span and terminal support elements (i.e. an elevation support element 384); the barrier system also includes (daisy) chained strap members i.e. the terminal girdles have two ring connectors.
It is to be understood herein that structures other than those shown above by way of example may be exploited as strap members, as supports and/or anchors for barrier systems and for kits to make such barrier systems (keeping in mind the purposes herein).
For example, other types of structures may be used to anchor strap members for barrier system purposes. Figs. 74 to 76 thus illustrate an alternate form of anchor attachment member 500 which may be attached to a pillar member by tensionable ring connectors 386 or be (releasably) bolted to a wall structure 502 as shown in fig. 76; one bolt being designated 504. The anchor attachment mechanism shown exploits an alternate form of an elevation support element which is described above with respect to figs. 3 to 5, namely an elevation support element which exploits closed U-shaped members designated by the common reference numeral 510 in figs. 74 to 76. As seen from fig. 76 carabiner type connectors 370 may be used to connect the strap members to the alternate elevation support element shown in figs. 74 and 75.

As may be understood from the above, a kit for a barrier system herein may comprise any combination of the herein described elevation support elements, strap members as well as anchor attachment members for the erection of a temporary barrier system. A
kit in accordance with the present invention may also be used (i.e. configured) to be associated with any type of suitable or desired anchor component so as to erect a desired or necessary barrier system (e.g. a safety barrier system).
