Definitions
- the disclosure relates generally to toe board systems for use with scaffolds and other items containing elevated platforms. More specifically, the disclosure is directed to adjustable toe boards having telescoping members.
- scaffolds are commonly used to elevate workers and materials as needed for a variety of tasks, such as construction, repair, and maintenance of structures, bridges, refineries, and the like.
- scaffolds are comprised of a framework support having poles, legs, or uprights to allow for elevation of one or more platforms or scaffold decks.
- the scaffolds have generally tubular shaped, e.g., round or square in cross section, vertical members, such as scaffold posts or poles, located at points located along the perimeter of the platforms.
- the sizes of the vertical members varies with each scaffold structure and may vary depending on the manufacture of the scaffold system to be used.
- the invention allows for near universal coupling of a toe board, whether adjustable or not, with the variously sized vertical members through the new and unique shape of the wedge pin that is used in the disclosed wedge connector.
- Toe boards are routinely utilized along the outermost edge of the various platforms situated in scaffolds to provide a barrier around the edge of the platform that will prevent the accidental rolling off or knocking off of tools, equipment, or other materials therefrom.
- the toe boards may also aid in preventing the workers from slipping at the platform's outermost edge.
- the sizing of the platforms varies; therefore, differing lengths of toe boards may be utilized. Adjustable toe boards allow for application to a multitude of lengths of platforms to provide the desired coverage thereof.
- the instant invention may be provided in any number of varying adjustable lengths to accommodate the various platform sizing.
- An exemplary embodiment of the invention includes a locking mechanism for use with the adjustable toe board to retain the toe board in its retracted position when necessary for transport, storage, or when the size of the portion of the platform the toe board will be used in requires the toe board to be in its fully collapsible state.
- the locking mechanism may be comprised of a self-contained latching member that is capable of automatic locking when the adjustable toe board is moved into its substantially retracted position.
- the locking mechanism may also be comprised of either a fixed or movable locking pin.
- the latching member may be removably attached to the toe board such that the latching member may be removed when replacement or repair of same is desired or necessary. This repair and/or replacement of the latching member may be accomplished on site either when the toe board is installed and in use or when the toe board is not in use. This ability for individual removal of the respective latching members allows for limited to no downtime when repairs or replacements of latching members are needed thereby allowing the job to proceed on schedule.
- an adjustable toe board is provided.
- the disclosed toe board is telescopic so that it may expand to accommodate a variety of platform lengths.
- Embodiments of the toe boards may be provided to be adjustable from about 60.96 cm (24′′) to 96.52 cm (38′′); from about 96.52 cm (38′′) to 167.64 cm (66′′), from about 167.64 cm (66′′) to 304.8 cm (120′′), or in any other range as desired or needed to fit any platform. While the range of adjustability may vary, the toe board may be used in its substantially retracted position as well depending on the dimensions of the subject platform.

- the resilient member 42 is capable of being compressed such that the space 152 between its opposing arms is reduced yet it is also capable of returning to its original form once the compression of the resilient member 42 is released, i.e., the resilient member 42 is capable of being spring loaded.
- the resilient member 42 has respective opposing ends on its opposing arms: a stop end 120 and a retaining member engagement end 122 .
- the base 118 of the resilient member 42 from which the opposing arms extend from, is disposed intermediate the stop end 120 and the retaining member engagement end 122 .
- the resilient member 42 is disposed within the cavity 35 of the latching member body 28 , wherein the base 118 of the resilient member 42 abuts the innermost interior wall 112 of the cavity 35 .
- the stop end 120 of the resilient member 42 abuts the internal protrusion 32 such that the positioning of the base 118 against the innermost interior wall 112 and the positioning of the stop end 120 against the internal protrusion 32 act to retain the resilient member 42 in position within the cavity 35 , whether the resilient member 42 is under pressure and in a compressed state or not.
- the width of the resilient member 42 is generally equal to the width of the cavity 35 proximate the internal protrusion 32 . While the width of the resilient member 42 is preferably the same as or slightly smaller than the width of the corresponding section of the cavity 35 , the width of the resilient member 42 may be uniform along the length of the resilient member 42 or may vary along the length of the resilient member 42 . Alternatively, the width of the resilient member 42 may not be the same or may be slightly smaller than the width of the corresponding section of the cavity 35 .
- Alternative embodiments of the resilient member 42 include coiled springs, barrel type springs, and other now known or later discovered spring or spring-like materials.
- a purpose of the resilient member 42 is to cause the retaining member 134 to extend at least partially through the aperture 38 of the latching member body 28 .
- a further purpose of the resilient member 42 is to compress in order to allow the retaining member 134 to be depressed by either a user, the locking plate 90 , or otherwise (see FIG. 6 C ).
- a further purpose of the resilient member 42 is to return to its un-compressed state once the compressive pressure on the resilient member 42 is removed and to act on the retaining member 134 by moving the retaining member 134 into its uncompressed position (see FIG. 6 B ). Therefore, the resilient member 42 may be as depicted in the exemplary embodiment or may be any type of resilient member 42 with spring-like resiliency that can perform the stated functions.
- the function of the retaining member 134 is to allow the locking aperture 160 of the locking plate 90 to temporarily place the retaining member 134 in a compressed state to allow a portion of the latching member 20 , proximate the retaining member 134 , to be inserted through the locking aperture 160 on the locking plate 90 .
- the retaining member 134 will then move to its uncompressed position once the pressure exerted on it by the locking plate 90 is released through the completion of the movement of the locking plate 90 over the retaining member 134 .
- the retaining end 135 of the retaining member 134 will extend out of the aperture 38 of the latching member 20 when in the retaining member's 134 uncompressed position thereby preventing the unintentional dislodgment of the latching member 20 from the locking plate 90 until a user unlocks the adjustable toe board 10 and extends it.
- pressure is applied to the striking plate 40 of the latching member 20 to press same down thereby compressing the resilient member 42 and moving the retaining member 134 from its un-compressed position to its compressed position whereby the retaining end 135 is lowered into the aperture 38 .
- the lowering of the retaining end 135 at least partially into the aperture 38 allows enough clearance for the locking aperture 160 of the locking plate 90 to slide over the retaining member 134 thereby allowing the adjustable toe board 10 to be unlocked and extended as needed.
- the depicted retaining end 135 of the retaining member 134 extends through and outside of the aperture 38 of the latching member body 28 .
- the retaining member engagement end 122 of the resilient member 42 is positioned within the cavity 35 proximate the front edge 148 of the aperture 38 .
- the retaining member 134 is movable between a compressed position ( FIG. 6 C ) and a non-compressed position ( FIG. 6 B ).
- the retaining member 134 is held in its substantially non-compressed position by the force placed upon it by the retaining member engagement end 122 of the resilient member 42 .
- the retaining member 134 extends along a portion of the aperture 38 proximate the retaining member engagement end 122 of the resilient member 42 wherein the retaining member engagement end 122 makes contact with the underside 72 of the retaining member 134 thereby exerting pressure on the retaining member 134 and positioning its cavity engagement surface 130 close to or against a portion of the striking plate engagement surface 48 of the aperture 38 .
- the retaining end 135 of the retaining member 134 extends through and out of the aperture 38 such that a portion of the retaining member 134 is extending outside of the interior of the latching member body 28 .
- the amount of the retaining member 134 that extends outside of the latching member body 28 is dependent on the corresponding locking aperture 160 of the locking plate 90 that will be utilized with the latching member 20 .
- the retaining end 135 of the retaining member 134 extends outside of the latching member body 28 enough such that the locking aperture 160 of the locking plate 90 will fit over the outer diameter of the latching body member 28 and over the retaining member 134 when resilient member 42 is in its compressed state and the retaining member 134 while it is in its compressed position yet the diameter of the locking aperture 160 of the locking plate 90 will be too small to fit over the retaining member 134 when it is in is un-compressed position such that the retaining member 134 will retain the adjustable toe board 10 in its substantially retracted position until the latching member 20 is purposely unlatched from the locking plate 90 .
- the engagement between the striking plate engagement surface 48 of the latching member body 28 and the cavity engagement surface 130 of the retaining member 134 when the resilient member 42 is installed and acting on the retaining member 134 will prevent the striking plate 40 from sliding out of the cavity 35 .
- the engagement of the two surfaces 48 , 130 also allows for the pivoting of the striking plate 40 when the retaining member 134 is moved to its compressed position and when the pressure on the retaining member 134 is released and it returns to its uncompressed position.
- the retaining member engagement end 122 may be slightly curved upward such that the tip 126 of the end 122 may engage at least a part of the underside 72 of the retaining member 134 to bias the retaining member 134 into its uncompressed position.
- the cavity engagement surface 130 depicted has four adjacent planes of varying angles that together create two notches 70 .
- the cavity engagement surface 130 may have any number of geometries and/or notches.
- the purpose of the engagement striking plate engagement surface 48 and the cavity engagement surface 130 is to allow for the interaction between the two surfaces 48 and 130 in order to maintain the striking plate 40 and its retaining member 134 in position within the cavity 35 .
- the width of the striking plate 78 is generally uniform; however, the striking plate 78 may have varying widths throughout in alternative embodiments.
- the striking plate is at least partially retained within a portion of the cavity 35 by its placement in relation to the striking plate engagement surface 48 and the resilient member 42 .
- the cavity engagement surface 130 of the striking plate 40 sits intermediate the retaining member 134 and the striking end 40 .
- the depicted exemplary embodiment of the striking plate 78 is of a single construction having all three sections: the striking end 40 , the cavity engagement surface 130 , and the retaining member 134 . It is understood that the striking end 40 , the cavity engagement surface 130 , and/or the retaining member 134 may alternatively be independent components retained independently in relation to the quick release latching member 20 or in any number of varying combinations.
- the striking end 40 , cavity engagement surface 130 , and retaining member 134 may be in alternative arrangements, such as having a single component comprised of both the retaining member 134 and the cavity engagement surface 130 , wherein the striking end 40 is formed out of the latching member body 28 itself.
- the referenced striking plate 78 would be formed from the retaining member 134 and the cavity engagement surface 130 , wherein the striking end 40 would be formed as part of the latching member body 28 .
- the striking end 40 may be an independent component, while the referenced striking plate 78 would be formed by the retaining member 134 and the cavity engagement surface 130 .
- a further alternative embodiment may not contain a striking end 40 .
- the striking end 40 has a tip 136 .
- the tip 136 is the leading edge of the striking end 40 that extends out of the cavity opening 36 of the latching member body 28 and away from the cavity 35 .
- the tip 136 is shaped such that it will easily pass through the aperture of the locking plate 90 .
- the tip 136 may form an acute angle.
- An exemplary acute angle is seventy-four degrees, though other angels may be utilized. While a tip 136 is not necessary for the present invention, when it is present it will be of a smaller size in relation to the portion of the striking end 40 proximate the cavity opening 36 whether the tip 136 it is shaped at an acute angle 108 or otherwise.
- the preferred embodiment of the tip 132 has a smaller surface area than at least a portion of the rest of the striking end 40 .
- the tip 132 will have a smaller surface area than the area of the striking end 40 adjacent to the tip 132 .
- the base 142 of the striking end 40 is located proximate the cavity engagement surface 130 .
- the base 142 is positioned outside of the cavity 35 and at least a portion of the base 142 is larger than the diameter of the cavity 35 such that at least a portion of the base 142 will not fit inside the cavity 35 .
- This sizing of the base 142 prevents full insertion of the striking end 40 into the cavity 35 . This sizing will further aid in the construction of the latching members 20 by allowing for proper positioning of the striking plate 78 inside the cavity 35 .
- An open spacing 144 is maintained between the base 142 section of the striking end 40 proximate the cavity opening 36 .
- This open spacing 144 allows for at least some movement of the striking end 40 in relation to the cavity opening 36 .
- the movement within at least a portion of the open spacing 144 by the striking end 40 may be in response to the application of downward pressure on the retaining member 134 or pressure on the striking plate 40 .
- the open spacing 144 may not be present in the alternative embodiments that utilize a striking end 40 that is formed from the latching member body 28 or that is otherwise fixedly connected to the latching member body 28 , such as by welding or bolting. Further, the open spacing 144 may not be present in alternative embodiments that contain a striking end 40 that is not part of the striking plate 78 , or that is otherwise not coupled to the retaining member 134 .
- the retaining member 134 of the striking plate 78 is positioned distal the tip 136 .
- the retaining member 134 is sized to at least partially extend through the latching member aperture 38 of the latching member body 28 .
- the latching member aperture 38 is sized to allow for downward movement of the retaining member 134 when it is depressed either by a user, the walls of the aperture on the locking plate 90 , or by any other means.
- the retaining member 134 has a front portion 133 that faces the direction of the cavity opening 36 , and a back portion 135 that faces the retaining nut 154 . Both the front 133 and back 135 portions extend out beyond the outer surface of the latching member body 28 .
- the front edge 148 of the aperture 38 is located proximate the front portion 133 of the retaining member 134 .
- the positioning of the retaining member 134 against the front edge 148 of the latching member body aperture 38 by the resilient member 42 allows the retaining member back portion 135 to remain extended away from the outer surface of the latching member body 28 such that it will act as a barrier preventing the latching member 20 from releasing from the locking plate 90 .
- the barrier created by the retaining member 134 thereby effectively retains or locks the adjustable toe board 90 in its substantially retracted position.
- the retaining member 134 is positioned at an ascending vertical angel in relation to the axis of the latching member body 28 such that it is cantilevered at the front edge 148 of the latching member aperture 38 and extends backward and upward away from the striking end 40 and towards the retaining nut 154 .
- the positioning of the retaining member 134 in combination with the latching member body 28 creates a larger surface area around this area of the latching member body 28 in relation to the outer surface of the adjacent section of the latching member body 28 .
- This larger surface area begins at the location of retaining member 134 proximate the front edge 148 of the latching member aperture 38 and increases along a part of the length of the retaining member 134 along the aperture 38 in the direction of the retaining nut 154 .
- any type of spring lock or latching mechanism may be utilized in some or all of the latching members, whether now know or later developed.
- the latching member is retained on the outer toe board 60 through attachment to the latching member anchor 88 .
- the latching member anchor 88 contained an aperture extending therethrough.
- a nut 156 is threaded onto the threaded end 34 of the latching member body 28 .
- the threaded end 34 of the latching member body is inserted into the aperture of the latching member anchor 88 and a retaining nut 154 is fastened onto the threaded end 34 of the latching member body that is extending out of the aperture of the latching member anchor 88 .
- the latching member 20 is then removably attached to the latching member anchor 88 .
- the latching member may be welded or otherwise permanently attached to the outer toe board 60 .
- any now known or later discovered method for retaining the latching member 20 onto the outer toe board 60 may be utilized.
- the retaining member 134 is a locking pin 157 that is capable of extending through a locking aperture 160 to couple the outer toe board 60 and the inner toe board 62 together in the substantially closed position utilizing a hooked latching member 20 that is attached to the outer toe board 60 .
- the locking pin 157 is a part of the latching member 20 , whereby movement of at least part of the latching member 20 will move the locking pin 157 .
- the inner board upright portion 136 has a locking aperture 160 extending therethrough, capable of accepting at least a portion of the locking pin 157 therein. Once the locking pin 157 is inserted into the locking aperture 160 , the latching member 20 will allow for removal of the locking pin 157 from the locking aperture 160 to allow the inner toe board 62 and the outer toe board 60 to move in relation to each other.
- the latching member 20 in FIGS. 8 A and 8 B is a curved portion 158 resembling a hook 158 .
- This shape allows any number of tools, ropes, straps, fingers or any similar devices to be utilized to pull the curved portion 158 thereby causing the locking pin 157 to move out of the locking aperture 160 which will release the outer toe board 60 and the inner toe board 62 from their coupling.

- the locking pin 157 extends through the locking aperture 160 and locks the adjustable toe board 10 in the substantially retracted position.
- the user pushes on the locking pin 157 thereby inserting enough of it into the spring lock latching member 20 to release the locking of the outer toe board 60 and inner toe board 62 to allow their free movement in relation to each other.
- the exemplary connecting member 100 is a wedge system 200 having a wedge pin capable of near universal use with the majority of scaffolds in use, and a fork 202 .
- An exemplary fork 202 is generally U-shaped having two legs extending from opposite sides of its midpoint: a first fork leg 206 and a second fork leg 208 .

- the wedge pin 200 is inserted into the fork 202 at its smaller end 214 through the second fork leg aperture 212 .
- the wedge pin 200 then has a wedge stop 216 , such as a rivet, installed at its smaller end 214 to prevent movement of the wedge pin through the second fork leg aperture 212 thereby retaining the wedge pin 200 in the fork 202 .
- the wedge stop 216 is insertable through the second fork leg aperture 212 due to its increased width in relation to the first fork leg aperture 210 .

Abstract
An adjustable toe board that is capable of adjustment to a number of varying lengths to accommodate various platform sizing. An exemplary embodiment of the invention includes a locking mechanism for use with the adjustable toe board to retain the toe board in its retracted position when necessary for transport, storage, or when the size of the portion of the platform the toe board will be used in requires the toe board to be in its fully collapsible state. A uniquely shaped wedge pin may be utilized to accommodate various sizes of posts when connecting a non-adjustable or an adjustable toe board to scaffolds and the like.
Description
- This application is a continuation of U.S. non-provisional application Ser. No. 15/955,680 filed on Apr. 17, 2018, which is incorporated herein by reference as if reproduced in full below.
- Not applicable.
- The disclosure relates generally to toe board systems for use with scaffolds and other items containing elevated platforms. More specifically, the disclosure is directed to adjustable toe boards having telescoping members.
- Scaffolds are commonly used to elevate workers and materials as needed for a variety of tasks, such as construction, repair, and maintenance of structures, bridges, refineries, and the like. There are many types of scaffolds, such as suspended scaffolding and supported scaffolds, such as tube and coupler, pole, mobile, frame and brace, cuplock and the like. Generally, scaffolds are comprised of a framework support having poles, legs, or uprights to allow for elevation of one or more platforms or scaffold decks. The scaffolds have generally tubular shaped, e.g., round or square in cross section, vertical members, such as scaffold posts or poles, located at points located along the perimeter of the platforms. The sizes of the vertical members varies with each scaffold structure and may vary depending on the manufacture of the scaffold system to be used. The invention allows for near universal coupling of a toe board, whether adjustable or not, with the variously sized vertical members through the new and unique shape of the wedge pin that is used in the disclosed wedge connector.
- Toe boards are routinely utilized along the outermost edge of the various platforms situated in scaffolds to provide a barrier around the edge of the platform that will prevent the accidental rolling off or knocking off of tools, equipment, or other materials therefrom. The toe boards may also aid in preventing the workers from slipping at the platform's outermost edge.
- The sizing of the platforms varies; therefore, differing lengths of toe boards may be utilized. Adjustable toe boards allow for application to a multitude of lengths of platforms to provide the desired coverage thereof. The instant invention may be provided in any number of varying adjustable lengths to accommodate the various platform sizing.
- An exemplary embodiment of the invention includes a locking mechanism for use with the adjustable toe board to retain the toe board in its retracted position when necessary for transport, storage, or when the size of the portion of the platform the toe board will be used in requires the toe board to be in its fully collapsible state. The locking mechanism may be comprised of a self-contained latching member that is capable of automatic locking when the adjustable toe board is moved into its substantially retracted position. The locking mechanism may also be comprised of either a fixed or movable locking pin.
- The latching member may be removably attached to the toe board such that the latching member may be removed when replacement or repair of same is desired or necessary. This repair and/or replacement of the latching member may be accomplished on site either when the toe board is installed and in use or when the toe board is not in use. This ability for individual removal of the respective latching members allows for limited to no downtime when repairs or replacements of latching members are needed thereby allowing the job to proceed on schedule.
- Various embodiments of an adjustable toe board are provided. The disclosed toe board is telescopic so that it may expand to accommodate a variety of platform lengths. Embodiments of the toe boards may be provided to be adjustable from about 60.96 cm (24″) to 96.52 cm (38″); from about 96.52 cm (38″) to 167.64 cm (66″), from about 167.64 cm (66″) to 304.8 cm (120″), or in any other range as desired or needed to fit any platform. While the range of adjustability may vary, the toe board may be used in its substantially retracted position as well depending on the dimensions of the subject platform.

- Referring to
FIGS. 1A, 1B, 2A, 2B, 3A, 3B, 3C, 3D, 4A, 4B, 4C, 4D and 5 , an exemplaryadjustable toe board 10 is shown with an exemplary embodiment of a locking mechanism 52. Theadjustable toe board 10 is generally comprised of aninner toe board 62, anouter toe board 60, a plurality of connectingmembers 100 and a locking mechanism 52. Theinner toe board 62 is at least partially retained along theouter toe board 60, wherein theinner toe board 62 and theouter toe board 60 are moveable in relation to each other. Each of theinner toe board 62 and theouter toe board 60 have at least one connectingmember 100 affixed thereon, wherein the connectingmembers 100 connect to either of the other toe boards (adjustable or not) and/or a portion of thescaffold 98, such as at thescaffold post 102. - Referring to
FIGS. 1A, 1B, 3A, 3B, 3C, 3D and 5 , theouter toe board 60 is an elongated generally L-shaped member having an outer boardupright portion 66 and anouter board base 64 extending therefrom. Theouter board base 64 may be integrally formed from the same piece of material as the outer boardupright portion 66 and may be permanently affixed to the outer boardupright portion 66 though welding or some other means, or may be removably affixed to the outer boardupright portion 66 through the use of fasteners, such as screws, tabs and slots, brackets, or rivets. The depictedouter toe board 60 has theouter board base 64 integrally formed from the same piece of material as the outer boardupright portion 66. - The
outer toe board 60 has an outer boardupper edge 21 extending along its unattached upper edge and an outer boardouter edge 23 extending along its unattached outer edge. More specifically, the outer boardupper edge 21 extends longitudinally along the length of the unattached upper edge of theupright portion 66, distal theouter board base 64. The outer boardouter edge 23 extends longitudinally along the length of theouter board base 64, distal the outer boardupright portion 66. The outer boardupright portion 66 and theouter board base 64 share a longitudinally extending outer board combinededge 22 along the length of theouter toe board 60 where the outer boardupright portion 66 and theouter board base 64 meet. - The
outer toe board 60 has an outer boardfirst side 24 and an outer boardsecond side 25. The outer boardfirst side 24 extends the length of the perimeter of the side of theouter toe board 60 between the outer boardupper edge 21 and outer boardouter edge 23, with the outer boardfirst side 24 being inclusive of the portion of the outer boardupper edge 21 and outer boardouter edge 23 adjacent thereto along the subject side of theouter toe board 60. The outer boardsecond side 25 extends the length of the perimeter of the side of theouter toe board 60 between the outer boardupper edge 21 and the outer boardouter edge 23, the outer boardsecond side 25 being distal the outer boardfirst side 24, with the outer boardsecond side 25 being inclusive of the portion of the outer boardupper edge 21 and outer boardouter edge 23 adjacent thereto along the subject side of theouter toe board 60. - Referring to
FIG. 3D , theouter toe board 60 comprises at least two retainingchannels 14. Anupright channel 16 is formed along at least a portion of the outer boardupper edge 21 extending along at least a portion of theinterior surface 56 of theouter toe board 60. The depicted exemplary embodiment shows theupright channel 16 extending the entire length of the outer boardupper edge 21 and shows theupright channel 16 extending along the entire length of theinterior surface 56 of theouter toe board 60 proximate the outer boardupper edge 21. In alternative embodiments, theupright channel 16 may be discontinuous along its length and/or may end prior to reaching one or more to the outer toe board's 60sides - A
base channel 18 is formed along at least a portion of the outer boardouter edge 23 extending along at least a portion of the outer boardinterior surface 56. The depicted exemplary embodiment shows thebase channel 18 extending the entire length of the outer boardouter edge 23 and shows thebase channel 18 extending along the entire length of theinterior surface 56 of theouter toe board 60 proximate the outer boardouter edge 23. In alternative embodiments, thebase channel 18 may be discontinuous along its length and/or may end prior to reaching one or more to the outer toe board's 60sides - The
upright channel 16 and/orbase channel 18 may be formed integrally from the same piece of material as theouter toe board 60 as is shown inFIG. 3D . Alternatively, any or all of the retainingchannels 14 may be permanently affixed to theouter toe board 60 though welding or some other means of fusing the retaining channel(s) 14 thereto. In a further alternative, the retainingchannels 14 may be removably affixed to theouter toe board 60 through the use of fasteners, such as screws, tabs and slots, brackets, or rivets. - The retaining
channels 14 are utilized to retain theinner toe board 62 in proximity to theouter toe board 60 such that theadjustable toe board 10 may be adjusted in length by movement of theinner toe board 62 in relation to theouter toe board 60 along thechannels 14. - In the exemplary embodiment depicted in
FIGS. 3A, 3C, 3D and 5 , the outer boardupright portion 66 contains aprotrusion 68 intermediate the outer boardupper edge 21 and the outer board combinededge 22. Theprotrusion 68 extends inward towards the outer boardouter edge 23. The exemplary embodiment of theprotrusion 68 extends along the entire length of theouter toe board 60. In alternative embodiments, theprotrusion 68 may not extend the entire length of theouter toe board 60. In alternative embodiments, theprotrusion 68 extends partially along the length of theouter toe board 60 proximate itssecond side 25 where the connectingmember 100 is coupled to theouter toe board 60. Theprotrusion 68 provides some space for limited movement of the connectingmember 100 along the connectingmember anchor 124. Alternatively, theouter toe board 60 does not have aprotrusion 68. - An
access point 84 is formed as an orifice extending through a section of the outer boardupright portion 66 proximate outer boardsecond side 25. Theaccess point 84 allows access for attachment of thelimit hook 30 onto theinner toe board 62 when theinner toe board 62 is installed in thechannels 14 and theadjustable toe board 10 is in a substantially retracted position. The fastening means, such as screws or bolts, that are used to attach thelimit hook 30 to theinner toe board 62 may be installed through theaccess point 84 to fasten thelimit hook 30 thereon. - The
limit plate 32 is fastened proximate the outer boardupper edge 21 and theupright channel 16 of theouter toe board 60. An engagement member 50 of thelimit plate 32 extends away from the outer boardupper edge 21 and towards the outer board combinededge 22. The engagement member 50 is positioned so that it will engage thelimit hook 30, that is installed on theinner toe board 62, in order to prevent the uncoupling of theouter toe board 60 and theinner toe board 62. The engagement member 50 prevents the uncoupling by providing a fixed member that thelimit hook 30 can hook onto when thelimit plate 32 andlimit hook 30 are in close proximity to each other, which occurs when theadjustable toe board 10 is in a substantially expanded position (as shown inFIG. 5 ). The action between the engagement member 50 of thelimit plate 32 and thelimit hook 30 prevents theinner toe board 62 from slipping out of the retainingchannels 14 and disengaging from theouter toe board 60. - A latching
member 20 is affixed to theexterior surface 57 of theouter toe board 60 proximate the outer board combinededge 22. The latchingmember 20 is positioned proximate thefirst side 24 of theouter toe board 60. A latchingmember anchor 88 is connected to theexterior surface 57 of theouter toe board 60 proximate the outer board combinededge 22. The exemplarylatching member anchor 88 is L-shaped wherein its base portion is attached to theouter toe board 60 and its upper section is extending upward away from theouter toe board 60. The upper section of the latchingmember anchor 88 contains an aperture extending therethrough which allows for coupling of the latchingmember anchor 88 with the latchingmember 20 to retain the latchingmember 20 onto theouter toe board 60. At least a portion of the latchingmember 20 is installed in the latchingmember anchor 88 such that the latchingmember 20 is effectively affixed to theouter toe board 60 with thestriking plate 40 of the latchingmember 20 facing towards thefirst side 24 of theouter toe board 60. Alternatively, any now known or later discovered means may be utilized to couple the latchingmember 20 to theouter toe board 60. - A latching
member aperture 86 is formed along a section of the outer boardupright portion 66 proximate the outer boardfirst side 24 and the outer board combinededge 22. The latchingmember aperture 86 extends from thefirst side 24 of theouter toe board 60 to a position intermediate thefirst side 24 of theouter toe board 60 and the installation site of the latchingmember anchor 88. The latchingmember aperture 86 is formed to allow the lockingplate 90 that is installed on theinner toe board 62 to interact with the latchingmember 20, wherein during the interaction between the lockingplate 90 and latching member 20 a portion of the lockingplate 90 may enter the latching member aperture 86 (as seen inFIGS. 1B and 2A ). - Referring to
FIGS. 1A, 1B, 4A, 4B, 4C and 4D , theinner toe board 62 is an elongated generally L-shaped member having an inner boardupright portion 136 and aninner board base 138 extending therefrom. Theinner board base 138 may be integrally formed from the same piece of material as the inner boardupright portion 136 and may be permanently affixed to the inner boardupright portion 136 though welding or some other means, or may be removable affixed to the inner boardupright portion 136 through the use of fasteners, such as screws, tabs and slots, brackets, or rivets. The depictedinner toe board 62 has theinner board base 138 integrally formed from the same piece of material as the inner boardupright portion 136. - The
inner toe board 62 has an inner boardupper edge 126 extending along its unattached upper edge and an inner boardouter edge 128 extending along its unattached outer edge. More specifically, the inner boardupper edger 126 extends longitudinally along the length of the unattached upper edge of the inner boardupright portion 136, distal theinner board base 138. The inner boardouter edge 128 extends longitudinally along the length of theinner board base 138, distal the inner boardupright portion 136. The inner boardupright portion 136 and theinner board base 138 share a longitudinally extending inner board combinededge 127 along the length of theinner toe board 62 where the inner boardupright portion 136 and theinner board base 138 meet. - The
inner toe board 62 has an inner boardfirst side 80 and an inner boardsecond side 82. The inner boardfirst side 80 extends the length of the perimeter of the side of theinner toe board 62 between the inner boardupper edge 126 and the inner boardouter edge 128, with the inner boardfirst side 80 being inclusive of the portion of the inner boardupper edge 126 and inner boardouter edge 128 adjacent thereto along the subject side of theinner toe board 62. The inner boardsecond side 82 extends the length of the perimeter of the side of theinner toe board 62 between the inner boardupper edge 126 and the inner boardouter edge 128, the inner boardsecond side 82 being distal the inner boardfirst side 80, with the inner boardsecond side 82 being inclusive of the portion of the inner boardupper edge 126 and inner boardouter edge 128 adjacent thereto along the subject side of theinner toe board 62. - In the exemplary embodiment depicted, the inner board
upright portion 136 contains aprotrusion 70 intermediate the inner boardupper edge 126 and the inner board combinededge 127. Theinner board protrusion 70 is shaped to fit around theouter board protrusion 68 when theinner toe board 62 andouter toe board 60 are coupled. Theprotrusion 70 extends inward towards the inner boardouter edge 128. The exemplary embodiment of theprotrusion 70 extends along the entire length of theinner toe board 62. In alternative embodiments, theprotrusion 70 may not extend the entire length of theinner toe board 62. In alternative embodiments, theprotrusion 70 extends partially along the length of theinner toe board 62 proximate itsfirst side 80 where the connectingmember 100 is coupled to theinner toe board 62. Theprotrusion 70 provides some space for limited movement of the connectingmember 100 along the connectingmember anchor 125. Alternatively, theinner toe board 62 does not have aprotrusion 70. - When coupled, the inner board
upper edge 126 is slid into theupright channel 16 of theouter toe board 60 and the inner boardouter edge 128 is slid into thebase channel 18 so that theinner toe board 62 may be installed onto theouter toe board 60. Theinner toe board 62 is movable in relation to theouter toe board 62 along the retainingchannels 14 between a substantially retracted position (shown inFIGS. 2 and 2A ) and a substantially extended position (shown inFIGS. 3 and 3A ). Theadjustable toe board 10 may be retained in its substantially retracted position, its substantially extended position, or any position therebetween when installed on a scaffold as needed. - The
limit hook 30 is fastened proximate the inner boardupper edge 126 and the inner boardsecond side 82 at the limithook installation location 140. When theinner toe board 62 is first installed on theadjustable toe board 10, once the inner boardupper edge 126 and the inner boardouter edge 128 are aligned with, and placed in, the retainingchannels 14, and theinner toe board 62 is positioned in its substantially retracted position in relation to theouter toe board 60, then thelimit hook 30 may then be fastened onto theinner toe board 62 through use of theaccess point 84 on theouter toe board 60. - The
limit hook 30 is shown as installed at the limithook installation location 140 inFIGS. 2A and 3A . Thelimit hook 30 has a hooking portion extending from theinterior surface 58 of theinner toe board 62 for connecting with and hooking onto the engagement member 50 of thelimit plate 32. The interaction between the engagement member 50 of thelimit plate 32 and thelimit hook 30, as seen inFIG. 5 , prevents the uncoupling of theinner toe board 62 from theouter toe board 60 when theadjustable toe board 10 is in its substantially extended position. - A locking
plate 90 is attached to theinner toe board 62 proximate the inner board combinededge 127 and the inner boardfirst side 80. The lockingplate 90 is L-shaped wherein its base is attached to theexterior surface 59 of theinner toe board 62, and its upper section is extending upward away from theinner toe board 62. The upper section of the lockingplate 90 contains a locking aperture 106 extending therethrough which allows for coupling of the latchingmember 20 with the lockingplate 90 to retain theadjustable toe board 10 in its substantially retracted position. At least a portion of the lockingplate 90 may extend within the latchingmember aperture 86 on theouter toe board 60 when theadjustable toe board 10 is in its substantially retracted position. - Referring to
FIGS. 6, 6A, 6B, 6C, 7A and 7B , an exemplary embodiment of the self-contained latchingmember 20 is shown. The latchingmember 20 comprises a latchingmember body 28 that is generally cylindrical in shape having a retainingend 94 and anopposite anchoring end 96. The latchingmember body 28 has acavity opening 36 at its retainingend 94 from which aninternal cavity 35 extends at least partially within the interior of the latchingmember body 28, wherein thecavity 35 ends at its innermostinterior wall 112. A threadedsurface 34 extends along at least a portion of the outer surface of the latchingmember body 28 proximate its anchoringend 96. - An
internal protrusion 46 protrudes into thecavity 35 of the latchingmember body 28 intermediate thecavity opening 36 and the innermostinterior wall 112. Theinternal protrusion 46 may be formed by placing enough pressure on the outside surface of the latchingmember body 28 to create adepression 44 along a portion of its outer surface, which will bend the material thereby causing theinternal protrusion 46. Alternatively, theinternal protrusion 46 may be formed by any now known or later discovered means. - The latching
member body 28 has anaperture 38 extending along at least a portion of its outer surface. Theaperture 38 extends through a sidewall of the latchingmember body 28 thereby creating a passage from the exterior of the latchingmember body 28 into itscavity 35. Theaperture 38 is positioned opposite theinternal protrusion 46. Thefront edge 148 of theaperture 38 is disposed proximate the retainingend 94 of the latchingmember body 28. Thefront edge 148 of theaperture 38 and the cavity sidewall intermediate thefront edge 148 and thecavity opening 36 define acavity engagement surface 48 for engaging portions of thestriking plate 78 and the retainingmember 134. - While a generally cylindrical latching
member body 28 is disclosed in the depicted exemplary embodiments, this shape is not a strict requirement. Alternative exemplary embodiments of the latchingmember body 28 may be cuboidal or prismed shaped, or of any other geometry that allows for the retainment of at least a portion of a retainingmember 134 and/or astriking plate 78 along a side of the latchingmember body 28 for releasably retaining theadjustable toe board 10 in its substantially retracted position. - A
resilient member 42 is retained within thecavity 35 of the latchingmember body 28. Theresilient member 42 shown is a curved strip of resilient material having aspace 152 extending between its opposing arms. Theresilient member 42 is capable of being compressed such that thespace 152 between its opposing arms is reduced yet it is also capable of returning to its original form once the compression of theresilient member 42 is released, i.e., theresilient member 42 is capable of being spring loaded. Theresilient member 42 has respective opposing ends on its opposing arms: astop end 120 and a retainingmember engagement end 122. Thebase 118 of theresilient member 42, from which the opposing arms extend from, is disposed intermediate thestop end 120 and the retainingmember engagement end 122. - The
resilient member 42 is disposed within thecavity 35 of the latchingmember body 28, wherein thebase 118 of theresilient member 42 abuts the innermostinterior wall 112 of thecavity 35. Thestop end 120 of theresilient member 42 abuts theinternal protrusion 32 such that the positioning of the base 118 against the innermostinterior wall 112 and the positioning of the stop end 120 against theinternal protrusion 32 act to retain theresilient member 42 in position within thecavity 35, whether theresilient member 42 is under pressure and in a compressed state or not. - The width of the
resilient member 42 is generally equal to the width of thecavity 35 proximate theinternal protrusion 32. While the width of theresilient member 42 is preferably the same as or slightly smaller than the width of the corresponding section of thecavity 35, the width of theresilient member 42 may be uniform along the length of theresilient member 42 or may vary along the length of theresilient member 42. Alternatively, the width of theresilient member 42 may not be the same or may be slightly smaller than the width of the corresponding section of thecavity 35. - Alternative embodiments of the
resilient member 42 include coiled springs, barrel type springs, and other now known or later discovered spring or spring-like materials. A purpose of theresilient member 42 is to cause the retainingmember 134 to extend at least partially through theaperture 38 of the latchingmember body 28. A further purpose of theresilient member 42 is to compress in order to allow the retainingmember 134 to be depressed by either a user, the lockingplate 90, or otherwise (seeFIG. 6C ). A further purpose of theresilient member 42 is to return to its un-compressed state once the compressive pressure on theresilient member 42 is removed and to act on the retainingmember 134 by moving the retainingmember 134 into its uncompressed position (seeFIG. 6B ). Therefore, theresilient member 42 may be as depicted in the exemplary embodiment or may be any type ofresilient member 42 with spring-like resiliency that can perform the stated functions. - A
striking plate 78 having two opposing ends, a retainingmember 134 and astriking end 40, is shown. While the depicted exemplary embodiment combines the retainingmember 134 andstriking end 40 on onesingle striking plate 78, this is not necessary as the retainingmember 134 may be a stand-alone component that is contained within theaperture 38 of the latchingmember body 28 by its engagement with theresilient member 42 and thecavity engagement surface 48, or otherwise, such that the retainingmember 134 will be positioned to perform the function of having a portion of same, the retaining end 104, extend through theaperture 38 yet be movable between a compressed position (as seen inFIG. 6C ) and a non-compressed position (as seen inFIG. 6B ) through the compression of theresilient member 42 or otherwise. The function of the retainingmember 134 is to allow the lockingaperture 160 of the lockingplate 90 to temporarily place the retainingmember 134 in a compressed state to allow a portion of the latchingmember 20, proximate the retainingmember 134, to be inserted through the lockingaperture 160 on the lockingplate 90. The retainingmember 134 will then move to its uncompressed position once the pressure exerted on it by the lockingplate 90 is released through the completion of the movement of the lockingplate 90 over the retainingmember 134. The retainingend 135 of the retainingmember 134 will extend out of theaperture 38 of the latchingmember 20 when in the retaining member's 134 uncompressed position thereby preventing the unintentional dislodgment of the latchingmember 20 from the lockingplate 90 until a user unlocks theadjustable toe board 10 and extends it. To release the locking mechanism 52 and expand theadjustable toe board 10, pressure is applied to thestriking plate 40 of the latchingmember 20 to press same down thereby compressing theresilient member 42 and moving the retainingmember 134 from its un-compressed position to its compressed position whereby the retainingend 135 is lowered into theaperture 38. The lowering of the retainingend 135 at least partially into theaperture 38 allows enough clearance for the lockingaperture 160 of the lockingplate 90 to slide over the retainingmember 134 thereby allowing theadjustable toe board 10 to be unlocked and extended as needed. - The depicted retaining
end 135 of the retainingmember 134 extends through and outside of theaperture 38 of the latchingmember body 28. The retainingmember engagement end 122 of theresilient member 42 is positioned within thecavity 35 proximate thefront edge 148 of theaperture 38. The retainingmember 134 is movable between a compressed position (FIG. 6C ) and a non-compressed position (FIG. 6B ). The retainingmember 134 is held in its substantially non-compressed position by the force placed upon it by the retainingmember engagement end 122 of theresilient member 42. The retainingmember 134 extends along a portion of theaperture 38 proximate the retainingmember engagement end 122 of theresilient member 42 wherein the retainingmember engagement end 122 makes contact with theunderside 72 of the retainingmember 134 thereby exerting pressure on the retainingmember 134 and positioning itscavity engagement surface 130 close to or against a portion of the strikingplate engagement surface 48 of theaperture 38. The retainingend 135 of the retainingmember 134 extends through and out of theaperture 38 such that a portion of the retainingmember 134 is extending outside of the interior of the latchingmember body 28. The amount of the retainingmember 134 that extends outside of the latchingmember body 28 is dependent on thecorresponding locking aperture 160 of the lockingplate 90 that will be utilized with the latchingmember 20. The retainingend 135 of the retainingmember 134 extends outside of the latchingmember body 28 enough such that the lockingaperture 160 of the lockingplate 90 will fit over the outer diameter of the latchingbody member 28 and over the retainingmember 134 whenresilient member 42 is in its compressed state and the retainingmember 134 while it is in its compressed position yet the diameter of the lockingaperture 160 of the lockingplate 90 will be too small to fit over the retainingmember 134 when it is in is un-compressed position such that the retainingmember 134 will retain theadjustable toe board 10 in its substantially retracted position until the latchingmember 20 is purposely unlatched from the lockingplate 90. - The engagement between the striking
plate engagement surface 48 of the latchingmember body 28 and thecavity engagement surface 130 of the retainingmember 134 when theresilient member 42 is installed and acting on the retainingmember 134 will prevent thestriking plate 40 from sliding out of thecavity 35. The engagement of the twosurfaces striking plate 40 when the retainingmember 134 is moved to its compressed position and when the pressure on the retainingmember 134 is released and it returns to its uncompressed position. - The retaining
member engagement end 122 may be slightly curved upward such that thetip 126 of theend 122 may engage at least a part of theunderside 72 of the retainingmember 134 to bias the retainingmember 134 into its uncompressed position. - The
cavity engagement surface 130 depicted has four adjacent planes of varying angles that together create twonotches 70. Of course, it is understood that thecavity engagement surface 130 may have any number of geometries and/or notches. The purpose of the engagement strikingplate engagement surface 48 and thecavity engagement surface 130 is to allow for the interaction between the twosurfaces striking plate 40 and its retainingmember 134 in position within thecavity 35. - In the exemplary embodiment shown, the width of the
striking plate 78 is generally uniform; however, thestriking plate 78 may have varying widths throughout in alternative embodiments. The striking plate is at least partially retained within a portion of thecavity 35 by its placement in relation to the strikingplate engagement surface 48 and theresilient member 42. Thecavity engagement surface 130 of thestriking plate 40 sits intermediate the retainingmember 134 and thestriking end 40. The depicted exemplary embodiment of thestriking plate 78 is of a single construction having all three sections: thestriking end 40, thecavity engagement surface 130, and the retainingmember 134. It is understood that thestriking end 40, thecavity engagement surface 130, and/or the retainingmember 134 may alternatively be independent components retained independently in relation to the quickrelease latching member 20 or in any number of varying combinations. - Alternatively, the
striking end 40,cavity engagement surface 130, and retainingmember 134 may be in alternative arrangements, such as having a single component comprised of both the retainingmember 134 and thecavity engagement surface 130, wherein thestriking end 40 is formed out of the latchingmember body 28 itself. In this case the referencedstriking plate 78 would be formed from the retainingmember 134 and thecavity engagement surface 130, wherein thestriking end 40 would be formed as part of the latchingmember body 28. - Alternatively, the
striking end 40 may be an independent component, while the referencedstriking plate 78 would be formed by the retainingmember 134 and thecavity engagement surface 130. A further alternative embodiment may not contain astriking end 40. - The
striking end 40 has atip 136. Thetip 136 is the leading edge of thestriking end 40 that extends out of the cavity opening 36 of the latchingmember body 28 and away from thecavity 35. Thetip 136 is shaped such that it will easily pass through the aperture of the lockingplate 90. Thetip 136 may form an acute angle. An exemplary acute angle is seventy-four degrees, though other angels may be utilized. While atip 136 is not necessary for the present invention, when it is present it will be of a smaller size in relation to the portion of thestriking end 40 proximate thecavity opening 36 whether thetip 136 it is shaped at anacute angle 108 or otherwise. - Generally, the preferred embodiment of the
tip 132 has a smaller surface area than at least a portion of the rest of thestriking end 40. Typically, thetip 132 will have a smaller surface area than the area of thestriking end 40 adjacent to thetip 132. - The
base 142 of thestriking end 40 is located proximate thecavity engagement surface 130. Thebase 142 is positioned outside of thecavity 35 and at least a portion of thebase 142 is larger than the diameter of thecavity 35 such that at least a portion of the base 142 will not fit inside thecavity 35. This sizing of thebase 142 prevents full insertion of thestriking end 40 into thecavity 35. This sizing will further aid in the construction of the latchingmembers 20 by allowing for proper positioning of thestriking plate 78 inside thecavity 35. - An
open spacing 144 is maintained between the base 142 section of thestriking end 40 proximate thecavity opening 36. Thisopen spacing 144 allows for at least some movement of thestriking end 40 in relation to thecavity opening 36. The movement within at least a portion of theopen spacing 144 by thestriking end 40 may be in response to the application of downward pressure on the retainingmember 134 or pressure on thestriking plate 40. - The
open spacing 144 may not be present in the alternative embodiments that utilize astriking end 40 that is formed from the latchingmember body 28 or that is otherwise fixedly connected to the latchingmember body 28, such as by welding or bolting. Further, theopen spacing 144 may not be present in alternative embodiments that contain astriking end 40 that is not part of thestriking plate 78, or that is otherwise not coupled to the retainingmember 134. - The retaining
member 134 of thestriking plate 78 is positioned distal thetip 136. The retainingmember 134 is sized to at least partially extend through the latchingmember aperture 38 of the latchingmember body 28. The latchingmember aperture 38 is sized to allow for downward movement of the retainingmember 134 when it is depressed either by a user, the walls of the aperture on the lockingplate 90, or by any other means. - The retaining
member 134 has afront portion 133 that faces the direction of thecavity opening 36, and aback portion 135 that faces the retainingnut 154. Both the front 133 and back 135 portions extend out beyond the outer surface of the latchingmember body 28. Thefront edge 148 of theaperture 38 is located proximate thefront portion 133 of the retainingmember 134. The positioning of the retainingmember 134 against thefront edge 148 of the latchingmember body aperture 38 by theresilient member 42 allows the retaining member backportion 135 to remain extended away from the outer surface of the latchingmember body 28 such that it will act as a barrier preventing the latchingmember 20 from releasing from the lockingplate 90. The barrier created by the retainingmember 134 thereby effectively retains or locks theadjustable toe board 90 in its substantially retracted position. - The retaining
member 134 is positioned at an ascending vertical angel in relation to the axis of the latchingmember body 28 such that it is cantilevered at thefront edge 148 of the latchingmember aperture 38 and extends backward and upward away from thestriking end 40 and towards the retainingnut 154. The positioning of the retainingmember 134 in combination with the latchingmember body 28 creates a larger surface area around this area of the latchingmember body 28 in relation to the outer surface of the adjacent section of the latchingmember body 28. This larger surface area begins at the location of retainingmember 134 proximate thefront edge 148 of the latchingmember aperture 38 and increases along a part of the length of the retainingmember 134 along theaperture 38 in the direction of the retainingnut 154. - In alternative embodiments, any type of spring lock or latching mechanism, slam latch, Norfolk latch, Suffolk latch, toggle latch, other latching mechanism, and/or other self-contained retaining mechanism, may be utilized in some or all of the latching members, whether now know or later developed.
- The latching member is retained on the
outer toe board 60 through attachment to the latchingmember anchor 88. The latchingmember anchor 88 contained an aperture extending therethrough. Anut 156 is threaded onto the threadedend 34 of the latchingmember body 28. The threadedend 34 of the latching member body is inserted into the aperture of the latchingmember anchor 88 and a retainingnut 154 is fastened onto the threadedend 34 of the latching member body that is extending out of the aperture of the latchingmember anchor 88. The latchingmember 20 is then removably attached to the latchingmember anchor 88. - Alternatively, the latching member may be welded or otherwise permanently attached to the
outer toe board 60. Alternatively, any now known or later discovered method for retaining the latchingmember 20 onto theouter toe board 60 may be utilized. - Referring to
FIGS. 8A and 8B , alternatively, the retainingmember 134 is alocking pin 157 that is capable of extending through a lockingaperture 160 to couple theouter toe board 60 and theinner toe board 62 together in the substantially closed position utilizing a hooked latchingmember 20 that is attached to theouter toe board 60. Thelocking pin 157 is a part of the latchingmember 20, whereby movement of at least part of the latchingmember 20 will move thelocking pin 157. The inner boardupright portion 136 has a lockingaperture 160 extending therethrough, capable of accepting at least a portion of thelocking pin 157 therein. Once thelocking pin 157 is inserted into the lockingaperture 160, the latchingmember 20 will allow for removal of thelocking pin 157 from the lockingaperture 160 to allow theinner toe board 62 and theouter toe board 60 to move in relation to each other. - The latching
member 20 inFIGS. 8A and 8B is acurved portion 158 resembling ahook 158. This shape allows any number of tools, ropes, straps, fingers or any similar devices to be utilized to pull thecurved portion 158 thereby causing thelocking pin 157 to move out of the lockingaperture 160 which will release theouter toe board 60 and theinner toe board 62 from their coupling. Once theinner toe board 62 andouter toe board 60 are placed in the desired position in relation to each other, thefork assemblies 100 may be attached to the tubes of the scaffold to hold the toe board in place. - Alternatively, the latching
member 20 may be a springlock latching member 20, having anelongated body 159 attached to the outer boardupright portion 66 along a portion of theexterior surface 57 of theouter toe board 60. The springlock latching member 20 has alocking pin 157. Thelocking pin 157 may be retractable into at least a portion of the springlock latching member 20. The inner boardupright portion 136 has a lockingaperture 160 extending therethrough proximate the inner board combinededge 127 and the inner boardfirst side 80. When theadjustable toe board 10 is in its fully retracted position, the lockingpin 157 extends through the lockingaperture 160 and locks theadjustable toe board 10 in the substantially retracted position. To release, the user pushes on thelocking pin 157 thereby inserting enough of it into the springlock latching member 20 to release the locking of theouter toe board 60 andinner toe board 62 to allow their free movement in relation to each other. - Referring to
FIGS. 9, 9A, 9B, 10, 10A and 10B , exemplary connectingmembers 100 are shown. The exemplary connectingmember 100 is awedge system 200 having a wedge pin capable of near universal use with the majority of scaffolds in use, and afork 202. - An
exemplary fork 202 is generally U-shaped having two legs extending from opposite sides of its midpoint: afirst fork leg 206 and asecond fork leg 208. Thelegs fork leg aperture 210 and a secondfork leg aperture 212. - The first
fork leg aperture 210 is wider in width and shorter in length than the secondfork leg aperture 212. This is shown more clearly inFIG. 10B . Thewedge pin 200 is inserted into thefork 202 at itssmaller end 214 through the secondfork leg aperture 212. Thewedge pin 200 then has awedge stop 216, such as a rivet, installed at itssmaller end 214 to prevent movement of the wedge pin through the secondfork leg aperture 212 thereby retaining thewedge pin 200 in thefork 202. This aids in keeping thewedge pin 200 in close proximity to thefork 202 to make for quick and easy installation when needed on site without the need to search for wedge pins 200 for use. Thewedge stop 216 is insertable through the secondfork leg aperture 212 due to its increased width in relation to the firstfork leg aperture 210. Alternatively, thewedge pin 200 may not have awedge stop 216 installed thereon. - The
wedge pin 200 is a generally flat member that has asmaller end 214 and an oppositelarger end 218, and along its length, aninterior side 220 and an oppositeexterior side 222. Thewedge pin 200 has afirst side 219 and asecond side 215. Thewedge pin 200 also has afront surface 226 and a back surface 228. Theinterior side 220 of thewedge pin 200 is referring to its position in the interior of thefork 202 against theobject 102, such as a scaffold vertical member, being a post, pole, or the like, that the connectingmember 100 is coupled to. Theexterior side 222 of thewedge pin 200 is referring to its position facing outward away from the interior of the fork where theobject 102 will be positioned, therefore, being on the exterior of thewedge pin 200 in relation to theinterior side 220. - The
interior side 220 of thewedge pin 200 has a general slope inward from a position proximate thelarger end 218 of thewedge pin 200 along the length to a point proximate thesmaller end 214. At approximately the midpoint between thelarger end 218 and thesmaller end 214 of thewedge pin 200, along theinterior side 220, theinterior side 220 slopes outward 224 away from the interior of thewedge pin 200. The start point of the outward slope in relation to thefirst side 219 of thewedge pin 200 may be between 65 and 90 mm. Preferably the start point of the outward slope is between 70 mm and 80 mm, and more preferably the start point is between 72 mm and 78 mm. Theoutward slope 224 extends for a predetermined length, at which point the remaining length of theinterior side 220 begins to again gradually slope in towards thesmaller end 214 to a point proximate thesmaller end 214. Theoutward slope 224 creates abump 224 along the length of theinterior side 220. - The
exterior side 222 of thewedge pin 200 has seven distinct changes in slope along its length. The differences in slope along the length of thewedge pin 200 on theexterior side 222 allow for varying interactions of theexterior side 222 with the firstfork leg aperture 210 and the secondfork leg aperture 212 to retain a toe board to a variety of sized and shapedobjects 102. Proximate thelarger end 218 of thewedge pin 200, theexterior side 222 begins to extend toward thesmaller end 214 at a first gradual slope inward 231 toward the interior of thewedge pin 200. At a point between thelarger end 218 and the midpoint along the length of theexterior side 222, the slope increases causing a first more pronouncedinward slope 232 along a portion of theexterior side 222. The start point of the first more pronouncedinward slope 232 in relation to thefirst side 219 of thewedge pin 200 may be between 25 mm and 50 mm. Preferably the start point of the first more pronouncedinward slope 232 is between 30 mm and 45 mm, and more preferably between 35 mm and 40 mm. - The first more pronounced

exterior side 222 of thewedge pin 200 returns to a gradual inward slope towards thesmaller end 214, a second gradualinward slope 233. The second gradualinward slope 233 may extend the length of between 15 mm and 30 mm. Preferably the length of the second gradualinward slope 233 is between 18 mm and 25 mm, and more preferably the length is between 19 mm and 23 mm. - Thereafter, the

In relation to theexterior side 222 surface proximate to the start point of the first pronouncedoutward slope 234 and intermediate the second gradualinward slope 233 and the first pronounced outward slope 234 (“measure point”), the first pronouncedoutward slope 234 may be between 1 mm to 10 mm away from the measure point at its farthest point outward. Preferably, the first pronounced outward slope's 234 furthest point outward is between 1.5 mm and 5 mm, more preferably the furthest outward point is between 2.5 mm and 3.5 mm. - The first pronounced
outward slope 234 may extend the length of between 3 mm and 15 mm. Preferably the length of the first pronouncedoutward slope 234 is between 4.5 mm and 10 mm, and more preferably the length is between 5.5 mm and 8 mm. - The start point of the first pronounced

inward slope 235 may extend the length of between 15 mm and 50 mm. Preferably the length of the third gradualinward slope 235 is between 22 mm and 40 mm, and more preferably the length is between 25 mm and 35 mm. - Thereafter, the
exterior side 222 of thewedge pin 200 begins a second more pronouncedinward slope 236 towards the interior of thewedge pin 200 in the direction of thesmaller side 215. The start point of the second more pronouncedinward slope 236 in relation to thefirst side 219 of thewedge pin 200 may be between 85 mm and 115 mm. Preferably the start point of the second more pronouncedinward slope 236 is between 95 mm and 110 mm, and more preferably between 100 mm and 110 mm. - The second more pronounced

The start point of the fourth gradualinward slope 237 in relation to thefirst side 219 of thewedge pin 200 may be between 90 mm and 130 mm. Preferably the start point of the fourth gradualinward slope 237 is between 100 mm and 125 mm, and more preferably between 113 mm and 123 mm. - The fourth gradual
inward slope 237 may extend the length of between 10 mm and 40 mm. Preferably the length of the fourth gradualinward slope 237 is between 15 mm and 35 mm, and more preferably the length is between 23 mm and 33 mm. - The various gradual inward slopes referenced above may be insignificant slopes along the set length of the
exterior side 222 of the wedge pin 2000 whereby the effect is no real slope at all. - All ranges disclosed herein are inclusive of the respective outer limits listed.
- The
wedge pin 200 may include a laterally elongated portion at itslarger end 218 proximate itsfirst side 219 to aid in handling thewedge pin 200 by the user, as shown inFIG. 9 . Thesmaller end 215 may be rounded to aid in inserting thewedge pin 200 into thefork leg apertures - The

When installed on anobject 102, thewedge pin 200 is removed from the firstfork leg aperture 210 to allow for insertion around anobject 102. Once inserted on around theobject 102 thewedge pin 200 is reinserted into the firstfork leg aperture 210 along itssmaller end 214 and thewedge pin 200 is pushed until pressure is asserted onto theobject 102 and thewedge pin 200 is wedged into position, seeFIG. 12 . The various sections along thewedge pin 200 allow for better placement in relation thereto to allow for retaining thetoe board 10 onto a greater number ofobjects 102. - Referring to
