DETAILED DESCRIPTION OF VARIOUS EMBODIMENTS

Further features and advantages will become more readily apparent from the following description of various embodiments as illustrated by way of examples only and in a non-limitative manner.

As used herein, the wording “and/or” is intended to represent an inclusive-or. That is, “X and/or Y” is intended to mean X or Y or both, for example. As a further example, “X, Y, and/or Z” is intended to mean X or Y or Z or any combination thereof.

It should be noted that the term “rectangular shape” means a shape of a rectangle defined as a quadrilateral with four right angles. The term “rectangular shape” also includes, but is not limited to, square shape. It should be understood that the four angles of the rectangle may each be smaller or larger than 90° by about 0 to about 15°.

The following examples are non-limitative.

Referring now to FIG. 3, shown therein is an example of a conventional scaffolding frame 300. For example, scaffolding frame 300 can be a Canadian standard scaffolding frame. The scaffolding frame 300 has a first and a second side posts 315 and 325, as well as a first scaffolding rod 310 and a second scaffolding rod 320. Such scaffolding frame 300 also has a third post 335 which connects the first scaffolding rod 310 with the second scaffolding rod 320. Inner rods 330 are typically coupled to the scaffolding frame 300 between one of the first and second side posts (315, 325) and the third side post 335, while the other portion of the scaffolding frame 300 has a scaffolding frame opening 305. The scaffolding frame opening 305 in FIG. 3 is defined by the first scaffolding rod 310, the second scaffolding rod 320, a first post 315, and the third post 335.

As shown at FIG. 3, the first scaffolding rod 310 may be positioned opposite the second scaffolding rod 320. For example, when used in the scaffolding system, the scaffolding frame 300 may be positioned so that the first scaffolding rod 310 may be positioned higher than the second scaffolding rod 320.

The inner rods 330 protect workers from falling (prevent falling of the workers from the scaffolding system). Additional scaffolding boards (not shown) can sit on the inner rods 330 of two scaffolding frames 300, thus providing additional storage for equipment or supplies. The inner rods 330 can also be used as a ladder.

Although workers can walk through the scaffolding frame opening 305, there may be a need to provide a barrier to protect workers from falling. It may be also necessary to have additional scaffolding boards sitting between two scaffolding frames 300. Such functionality may be needed on demand, while using standard scaffolding frames and the accessory may need to be easily removable.

It should be noted that other types of scaffolding frames can provide scaffolding frame openings, which may need to be filled, on demand, by an accessory that can protect the workers from falling from the scaffolding system or to provide support for additional scaffolding boards. For example, the scaffolding accessory as described herein can be used for this purpose.

Referring now to FIGS. 1, 2A and 2B, shown therein is a scaffolding accessory 100 in perspective view (FIG. 1), front view (FIG. 2A) and side view (FIG. 2B). The scaffolding accessory 100 comprises an accessory frame 120, a first pair 13 of first legs 130a, 130b, and a second pair 14 of second legs 140a, 140b.

In at least one embodiment, the accessory frame 120 has a rectangular shape. For example, the accessory frame 120 can have a square shape. The dimensions (height, width) and the ratio of height vs. width of the accessory frame 120 can vary depending on the dimensions of the scaffolding frame opening 305 so that the accessory frame 100 can be releasably secured inside the scaffolding frame opening 305.

For example, the accessory frame 120 can have four frame bars 121, 122, 123, 124. For example, the side frame bars 121 and 122 can be adjacent to posts 325, 335 that define the scaffolding opening 305 of the scaffolding frame 300. For example, the accessory frame 120 may be made by soldering together independent bars. For example, the frame bars (121, 122, 123, 124) may have rectangular or round cross-section.

Each first leg 130a, 130b is connected to the accessory frame 120 and has a first U-shaped member 134a, 134b. Each first leg 130a, 130b may also have a first pillar member 136a, 136b. For example, each U-shaped member 134a, 134b may be connected to the accessory frame 120 via a first pillar member 136a, 136b. In at least one embodiment, the first U-shaped members 134a, 134b are dimensioned to receive the first scaffolding rod 310, when the scaffolding accessory 100 is being secured to the scaffolding frame 300.

Shown therein is also the distance L between the curved portions 138 of the first U-shaped members 134a, 134b and the curved portions 148 of the second U-shaped members 144a, 144b.

The lengths of the two side portions 137, 139 of each of at least one of the second U-shaped members 134a, 134b may depend on the distance between the first scaffolding rod 310 and the second scaffolding rod 320, as well as on the lengths of the second U-shaped members 144a, 144b. The lengths of the two side portions 137, 139 of each of at least one of the second U-shaped members 134a, 134b may also depend on the distance L between the curved portions 138 of the first U-shaped members 134a, 134b and the curved portions 148 of the second U-shaped members 144a, 144b.

In at least one embodiment, the distance L between the curved portions 138 of the first U-shaped members 134a, 134b and the curved portions 148 of the second U-shaped members 144a, 144b may be chosen so that when the scaffolding is being installed on the scaffolding frame 300, the first U-shaped members 134a, 134b can receive the first scaffolding rod 310 so that the second U-shaped members 144a, 144b can be inserted and mounted on the second scaffolding rod 320. The lengths of the first U-shaped members 134a, 134b may be chosen so that when the scaffolding accessory 100 sits on the second scaffolding rod 320, at least some portions of the U-shaped members 134a and 134b can touch the first scaffolding rod 310, and the scaffolding accessory can be secured to the first scaffolding rod 310 by means of leg fasteners 185. The leg fasteners 185 may fasten the side portions 137, 139 of the first U-shaped members 134a, 134b through the leg bores 165 to secure the first legs 130a, 130b to the first scaffolding rod 310.

In at least one embodiment, the first U-shaped members 130a, 130b may be longer than the second U-shaped member 140a, 140b. For example, the length of the side portions 137, 139 may be at least two times greater than the diameter of the first scaffolding rod 310 or second scaffolding rod 320. For example, the length of side portions 137, 139 of at least one of the first U-shaped member 130a, 130b may be at least three times greater than the diameter of the first scaffolding rod 310 or the second scaffolding rod 320.

In at least one embodiment, two side portions 147 and 149 of each of the second U-shaped members 144a and 144b are dimensioned to at least partially embrace at least one portion of the second scaffolding rod 320 so that when installed, the scaffolding accessory 100 may be secured to the scaffolding frame 300 and cannot be shifted away from the second scaffolding rod 320.

For example, the curved portion 148 of the second U-shaped members 144a and 144b may be an arc with radius approximately equal to or larger than the radius of the second scaffolding rod 320. For example, the curved portion 138 of the first U-shaped members 134a and 134b may be an arc with radius approximately equal to or larger than the radius of the first scaffolding rod 320.

For example, referring to FIGS. 2A and 2B, L₁ may be, for example, approximately 7 ¼ inches, L may be, for example, approximately 40 ⅜ inches, L₂ may be, for example, approximately 2 ⅛ inches. For example, the width W of the accessory frame 120 may be approximately 27 ¾ inches. For example, the distance D between the side portions 137, 139 (and 147, 149) of the U-shaped members 134a, 134b, 144a, 144b may be approximately 2 ⅛ inches.

Referring now to FIG. 4, shown therein is the scaffolding accessory 100 releasably secured in the scaffolding frame 300. When the scaffolding accessory 100 is installed (releasably secured), the second U-shaped members 144a and 144b abut an inside portion 321 of the second scaffolding rod 320. This permits the scaffolding accessory 100 to sit on the second scaffolding rod 320.

According to at least one embodiment, to mount the scaffolding accessory 100 on to the scaffolding frame 300, the first U-shaped members 130a, 130b of the scaffolding accessory 100 can receive the first scaffolding rod 310 so that that the second U-shaped members 140a, 140b can be arranged to sit on the second scaffolding rod 320 and abut it.

In at least one embodiment, the first U-shaped members 134a, 134b define bores 165 that are dimensioned to receive leg fasteners 185 to releasably secure the accessory frame 100 to the first scaffolding rod 300. For example, the bores 165 may be located on the side portions 137 of the first U-shaped members 134a, 134b. The first U-shaped members 130a, 130b can then be secured to the first scaffolding rod 310 with leg fasteners 185.

To releasably secure the scaffolding accessory 100 to the scaffolding frame 300, the leg fasteners 185 can be used. For example, the leg fasteners 185 may be hitch pins with R-clips (bridge pins), nuts and bolts etc. Other types of fasteners can also be used.
