The ladder section 20 is comprised of a plurality of rungs 22 stretching across the gap 24 between vertical supports 26, 28. The ends of the rungs 22 may be curved or otherwise shaped to conform to the geometry of the exterior of the vertical supports 26, 28 to seamlessly attach thereto. The rungs 22 may be welded onto the vertical supports 26, 28 or otherwise coupled thereto either permanently or removably. The uppermost rung 22 and the lowermost rung 22 may be of a different shape than the remaining rungs 22 as the uppermost rung 22 and the lowermost rung 22 may be of the same shape and material as the vertical supports 26, 28.
Some of the rungs 22, may consist of three elongated sides. With two of the elongate sides flanking the third and being connected thereto. Wherein the three elongated sides when connected together define a space within the interior of the sides.
Some of the vertical supports 26, 28 extend past the lowest rung 22 and to the floor to support the scaffold end section 16 on the ground. It is not necessary for all of the vertical supports 26, 28 to extend to the ground. As shown, the middle vertical support 28 does not extend all the way down to the ground but ends at its connection to the lowermost rung 22. In alternative embodiments both vertical supports 26, 28 for the ladder section 20 may extend to the ground.
In some embodiments one or more of the rungs 22 may have anti-slip properties 32. A variety of anti-slip properties 32 may be utilized such as the depicted anti-slip tape 32a positioned on the top rung 22 in the depicted embodiment or, as is depicted on the center rungs 22, protrusions 32b extending from the rungs 22 may be utilized. The protrusions 32b may be integrally formed along the rung 22 or may be externally placed there. The protrusions 32b may be continuous along the surface of the rung 22 or may be discontinuous. The protrusions 32b may form a straight line or they may not form a straight line. The anti-slip properties 32 may be uniform along all the rungs 22 of the ladder section 20 or, as is depicted in
The leg section 40 is comprised of a vertical support 30 and one or more horizontal connectors 42. The vertical support 30 extends to the floor to support this side of the end section 16. Two horizontal connectors 42 are positioned along the length of the vertical support 30. The first horizontal connector 42 is positioned proximate the lower end of the vertical support 30, and the second horizontal connector 42 is positioned proximate the upper end of the vertical support 30. The number of horizontal connectors 42 depends on the number of horizontal extension coupling members 38 that will be utilized with the end section 16 as the horizontal extension coupling members 38 connect the leg section 40 through the horizontal connectors 42 to the ladder section 20. In the depicted exemplary embodiment, the horizonal connectors 42 consist of a protrusion 44 having a male connector 46 extending therefrom. The depicted protrusion 44 is tubular however any geometry may be used as long as it is compatible with the male connector 46 that is coupled with it.
The horizontal extension coupling members 38 consists of an extension member 48 having a female connecting end 50 and an opposite male connecting end 52. The male connecting end 52 comprises a coupling pin 64 extending from the extension member 48. The coupling pins 64 follow the geometry of the extension member 48 and insert inside a portion of the extension member 48. A portion of the coupling pin 64 is contained within a portion of the extension member 48 by pinching a portion of the extension member 48 into the coupling pin 64 or by any other type of fastening whether now known or later discovered.
The extension member 48 will be of varying lengths depending on the desired width of the end sections 16, 18. Exemplary embodiments showing exemplary differing lengths are included in
In the depicted embodiment, the uppermost rung 22 and the lowermost rung 22 of the ladder section 20 have female connecting ends 34 located proximate its middle vertical section 28. The rungs 22 along the ladder section 20 may be of different compositions such that the top and bottom rungs 22 may be tubular to more easily accept the connector 52 of the extension member 48. The top and bottom rungs 22 may also be of any other geometry so long as the geometry of the connecting end 34 will accept the corresponding connecting end 52 of the extension member 48, or the leg section 40 when directly coupling.
To assemble the end section 16, each horizonal extension coupling member 38 is installed between the ladder section 20 and the leg section 40 by coupling the respective male and female connection ends 50, 42 and 34, 52. Fasteners 54 are then secured to each connection 50, 42 and 34, 52 to secure same.
The fasteners 54 may consist of nuts and bolts (as shown in 8A, 8B, 9A, 9B, 10A, and 10B), bolts and wingnuts (as shown in
The depicted snap clip consists of a clip shell 90 and a rivet pin 92. The clip shell 90 is curved with an orifice 94 extending though the top, the orifice will accept a portion of the rivet pin 92. The clip shell has a wide opening 96 opposite its orifice 94. The clip shell 90 is shaped to extend around the connection locations where the extension members 48 connect to the leg section 40 and the ladder section 20. The rivet pin 92 is an elongated pin that fits in the corresponding orifices on the end section 16 with the upper end extending through the orifice 94 of the clip shell 90. The rivet pin 92 is secured to the clip shell 90 and the corresponding section of the end section 16. The rivet pin 92 keeps the clip shell 90 from having lateral movement and the various snap clips when installed fasten the ladder section 20, leg section 40, and horizontal extensions 38 together.

The cross-brace members 60 are coupled to two loose brace members 62 in order to form the full-sized cross brace which is then used to couple the first end section 16 to the second end section 18. The loose brace members 62 each have a length and each have a cross brace connecting end 106. The depicted loose brace members 62 have a male connector pin 108 extending from each’s cross-brace connecting end 106. The cross-brace members 60 each have a female connector 110 proximate each’s cross-brace connecting end 104. The members 60, 62 are connected by inserting the male connecting pin 108 of the loose brace member 62 into its corresponding female connecting end 110 of the elongated brace member 100, 102. The connectors may be switched wherein the male connecting end may extend from the elongated brace members 100, 102 and the loose brace members 62 may have the female connecting end. This is true of all such connectors in this disclosure, the male and female connectors of all the connectors disclosed herein may be switched in a way not expressly stated and it will still fall under the disclosure hereof.
The cross-brace members 60 and the loose brace members 62 are connected utilizing an internal spring rivet 116,
The depicted protrusions 124 shown in
This type of spring rivet or other types of pin springs or spring rivets may be used in a similar manner to connect any of the pieces discussed herein that have also been disclosed to connect through connection means such as nuts and bolts, spring clamps or otherwise. Similarly, the spring rivet 116 described here to attach the loose brace members 62 to the cross-brace members 60 may be replaced with other fastener methods, such as nuts and bolts or otherwise. In other words, the different fasteners are interchangeable as the situation allows.

The depicted latching member 70 comprises a body 72 and a connecting head 74. The connecting head 74 may be of various shapes, two examples of varying shapes are shown in
The latching member body 72 contains a slit 76 extending through a portion thereof. A retaining member 78 is movably attached to the latching member 70 at the latching member body slit 76. The retaining member 78 contains two orifices 80 extending therethrough, with the first orifice 80a acting to receive a rivet or other means for containing the retaining member 78 onto the latching member body 72. The second orifice 80b is shaped to allow it to accept a rivet or other connecting member therein yet still allow the retaining member 78 to freely move along the connecting member of the second orifice 80b and within the slit 76 without allowing for spinning of the retaining member 78 around the first orifice 80a. The second orifice 80b retains the retaining member 78 yet still allow it to move freely between a position wherein the body of the retaining member 78 is substantially within the body of the latching member body 72 to a position wherein at least a portion of the base 82 of the retaining member 72 extends out of the body 72, via the slit 76, of the latching member 70 such that same will act to increase the outer diameter of at least a portion of the latching member body 72.
The cross-brace members 60 have end section connecting ends 112 opposite the cross-brace connecting ends 104. The end section connecting ends112 of the cross-brace members 60 have an orifice 136 extending through each. Each orifice 136 passes over the corresponding latching member 72, moving the retaining member into its non-retaining position thereby allowing the end section connecting ends 112 of the cross-brace members 60 to removably couple to the end section 16, 18. Once the orifice 136 passes over the retaining member 78, the retaining member 78 moves into its retaining position as depicted in
The same procedure is used to attach the loose brace members 62 to the respective end sections 16, 18. The loose brace members 62 have end section connecting ends 114 opposite their respective cross-brace connecting ends 106. The loose brace members 62 have orifices 138 extending through a portion of each’s end section connecting ends 114. The orifices 138 are positioned over the latching member 70, specifically over the latching member body 72 which acts on the retaining member 78 moving it into the slit 76 allowing the orifice 138 to move over and then release the retaining member 78 once the loose brace member end section connection end 114 is located intermediate the retaining member 78 and the latching member head 74. The release of the retaining member 78 increases a portion of the outer diameter of the latching member 70 such that it is then greater than the inner diameter of the orifice 138 when the retaining member 78 is in its extended position (as shown in
