AUSTRALIA
Patents Act 1990 COMPLETE SPECIFICATION STANDARD PATENT Applicant(s): NEALE DE MALMANCHE Invention Title: A SAFETY SYSTEM AND APPARATUS FOR PEOPLE WORKING ON ELEVATED STRUCTURES The following statement is a full description of this invention, including the best method of performing it known to me/us:
*I
2 A SAFETY SYSTEM AND APPARATUS FOR PEOPLE WORKING ON ELEVATED STRUCTURES The present invention relates to a safety system and apparatus for limiting the distance a person may fall from a roof of a building.
It has long been recognized that people working on an elevated structure are at risk of falling and suffering serious injury or death. For example, people tiling the roof of a house or painting the facia boards around a house are at risk of loosing their footing and falling. In the past, there has been extensive emphasis placed on safe work practices in both industrial and residential work sites. A major component in safe work practices particularly when working on an elevated structure involves the use of safety systems and apparatuses.
One such apparatus that is currently known involves assembling a number of vertical posts around the edge of the roof of a building and bolting interconnecting upper S:o. and lower rails to the posts. When assembled, the device forms a temporary fence around the edge of the roof to prevent people from falling from the roof. However, this 25 type of device has the disadvantage of being both time consuming to assemble and expensive to hire for the duration of a particular job. A further disadvantage with this known apparatus is that it provides no protection or at best, only limited protection, to the person assembling 30 the device which is inherently dangerous as the task requires working close to the peripheral edge of the roof of a building. In any event, even when the apparatus is assembled, there is still a chance of a person falling *:ooo under, between or over the rails that form the temporary fence.
Moreover, the apparatus that has been previously disclosed H:\HeenF\Keep\PQ5669.doc 16/02/01 3 offers no protection against injury to a worker falling through roofing framework at a distance inside the peripheral edge of the roof. This is particularly a problem for workers who install or lay roofing material, such as corrugated iron or roofing tiles.
It is therefore an object of the present invention to provide an improved safety system and apparatus.
According to the present invention there is provided a safety system suitable for limiting the distance a person may fall from a building, the safety system including: a safety line connectable at one end to a person, an anchoring means connectable to an opposite end of the safety line, and a guiding device for the safety line, whereby, in use of the system, the guiding device is mounted to a building and positions the safety line at a location from which the person connected to the line will be suspended in the event that the person falls from the building, wherein the location and the length of the safety line are selected to limit the distance the person can 25 fall.
Preferably, the system further includes a mounting assembly for mounting the guiding device to a building.
30 According to the present invention there is also provided an apparatus for limiting the distance a person may fall from a building, the apparatus including: *goo a guiding device for a safety line, and a mounting assembly for mounting the guiding device to a building, H:\HelenF\Keep\PQ5669.doc 16/02/01 *1 4 whereby, in use of the apparatus, one end of the safety line is connected to the person and an opposite end of the safety line is connected to an anchoring means and the mounting means is able to mount the guiding device to a building and position the safety line at a location from which the person connected to the line will be suspended in the event that the person falls from the building, wherein the location and the length of the safety line are selected to limit the distance the person can fall.
The system and apparatus of the present invention is therefore able to be used to limit the distance a person can fall either through a roof or over the peripheral edge of a roof.

Preferably, the spacing member has an elongated shape and can be positioned to extend laterally across adjacent second support members for mounting to the adjacent second support members.
H:\He1en\Keep\PO5669.doc 16/02/01 7 According to an alternative embodiment of the present invention, the mounting assembly is suitable for mounting the guiding device to roofing framework typically used in industrial buildings and in particular, the mounting assembly is suitable for mounting the guiding device to steel beams. For example, the lower assembly is connectable to a first support member, such as a steel Ishaped beam and the upper assembly is connectable to two second support members, such a steel C-shaped purlins or battens. A steel C-shaped purlin or batten is normally supported by steel I-shaped beams. Roofing material, such as corrugated iron, can then be secured to the purlins or battens.
Preferably, the lower assembly includes: two clamping members that can be clamped to the first support member, and tie members that interconnect the clamping members and the guiding device, whereby in use, the clamping members are clamped to the first support member in locations such that the spacing between the clamping members and the guiding device is less than the length of the tie members, thereby enabling downward load from the guiding device to be transferred by 25 the tie members and the clamping members onto the first support member.
eooo* .The clamping members are configured to straddle and clamp onto flanges of the first support member. For example, in 30 the situation where the first support member is an I-shaped "-.beam, it is preferred that the clamping members are configured to straddle and clamp onto the lower flange of ~the I-shaped beam. It is also preferred that the lower and S• upper assemblies are spaced apart as far as possible relative to each other so as to provide maximum support for the guiding device.
H:\HeIenF\Keep\PQ5669.doc 16/02/01 8 Typically, the spacing between purlins varies between particular buildings. Therefore, in order for the upper assembly to be connectable to two second support members, such as two adjacent steel C-shaped purlins, it is preferred that the upper assembly is adjustable to enable the upper assembly to be connected to purlins of any commonly found spacing.
Preferably, the upper assembly includes: two clamping members that are able to be clamped to separate second support members, tie members that interconnect the clamping members and the guiding device, and an adjustment means that allows the tie member to be connected to the clamping member at a number of different positions relative to the second support member.

Figure 3B illustrates an exploded view of the guiding device and mounting assembly from figure 3A.
Figure 4 is a side elevation of a lower assembly of the mounting assembly in figure 3.
H:\HelenF\Keep\PQ5669,doc 16/02/01 11 Figure 5 is a cross sectional view through the line a-a in figure 4.
Figure 6 is a side elevation of an upper assembly of the mounting assembly in figure 3.
As can be seen from the figures 1A to 2, the safety system of a first preferred embodiment of the present invention includes a guiding device a safety line an anchoring means and a mounting assembly The safety system is used for limiting the distance a person (42) may fall from a building.
The guiding device is in the form of an elongated steel tubing having an opening (40) at an upper end of the tubing, a lower opening (41) at a lower end of the tubing and an internal passageway through which the safety line is threaded.
The person (42) is connected to the safety line of the safety system via a safety harness (43).
o• The safety line is constituted by three different portions. The first portion interconnects the person's 25 safety harness (43) and a second portion of the safety line. The second portion is a length of chain which is threaded through the steel tubing The third portion interconnects the length of chain and the anchoring means It is possible for more than one of the first portion to be connected to the second portion at any one time, thereby enabling several people to use the system and apparatus 0:00. .simultaneously.
The first and second portions of the safety line include suitable means for selecting the length of the first and H:\He1enF\Keep\PQ5669.dOc 16/02/01 12 second portions so as to limit the distance a person may fall when suspended by the safety line. In particular, the first portion of the safety line includes suitable means for enabling the person to readily select the length of the first portion of the safety line while working on the building.
Figure 1A illustrates the guiding device mounted to a standard wooden housing truss at the apex of the roof line.
When a person losses their footing and either falls through the roof or over the edge of the roof, the person will be suspended by the safety line from the opening (40) at the upper end of the steel tubing.
As can be seen from the figures, the height of the opening defined by the steel tubing relative to the height from which the person falls is a factor in the distance by which the person may fall if their footing is lost. In the preferred arrangement illustrated, the opening (40) of the guiding device is approximately 1.7 meters above the apex of the roofing framework.
Figure 2 illustrates in greater detail the mounting of the guiding device to a ridge that extends between the apex S:i 25 of two adjacent rafters and ceiling joists of the building. Specifically, the guiding device is mounted by way of an upper assembly identified generally by reference numeral and a lower assembly identified generally by reference numeral The upper assembly supports an upper end of the guiding device in such a manner as to prevent lateral movement of 0:°0 the upper end of the guiding device. The upper assembly 0:006: includes a holding member in the form of a sleeve (19) slidably fitted over the steel tubing and a clamp for clamping the sleeve (19) to the ridge Extending from the side wall of the sleeve is a member which forms a U- H:\HeenF\Keep\PQ5669.doc 16/02/01 13 shaped formation with the sleeve which can be fitted over the ridge The U-shaped formation also includes a screw hole such that a screw (10) with a flattened end can be tightened against the ridge to clamp the upper assembly to the framework.
Located on the steel tubing below the upper assembly is a securing means in the form of a collar (11) having an adjustable tightening screw that passes through a wall of the collar and engages the guiding device, thereby allowing the location of the collar to be repositioned along the length of the guiding device. The collar is preferably positioned immediately below the upper assembly so as to prevent upward movement of the steel tubing through the sleeve (19).
The lower assembly includes a supporting means in the form of a support plate (13) suspended below one or more ceiling joists by a plurality of J-shaped bolts The support plate (13) prevents downward movement of the guiding device and distributes downward load to the ceiling joists through the J-shaped bolts. The lower assembly go further includes a locating means in the form of a sleeve (18) into which the steel tubing is located. Welded to .oooo opposed sides of the locating means are spacing members (17) having holes therein for receiving the J-shaped bolts (14) and thereby preventing lateral movement of the lower section of the steel tubing The support plate (13) has a hole to allow the chain to pass therethrough.
Illustrated in figure 2 are additional spacing members located either side of the spacing members The additional spacing members (20) assist in distributing load applied to the support plate (13) to various points along the ceiling joists. Whilst not illustrated in the figures, the spacing members (17, 20) are elongated and are positioned to extend laterally across adjacent ceiling H:\HelenF\Keep\P05669.doc 16/02/01 14 joists for mounting to the adjacent ceiling joists.
A further feature not illustrated in the figures is a disc that is welded to the inside surface of the sleeve (18) and abuts against the lower end of the steel tubing. Downward load is thereby transferred to the lower assembly via the disc. The disc also includes a hole to allow the chain to be threaded therethrough.
As can be seen in figure 2, the safety line includes a stopping means in the form of a large chain link having a diameter larger than the inside diameter of the steel tubing. Therefore, in the event that the anchoring means fails, the large chain link (15) is able to engage the steel tubing and/or the base plate to prevent the chain from being pulled upwardly out of the steel tubing.
Figure 2 also illustrates a supporting device in the form of a shear bolt (16) passing through opposed side walls of the steel tubing and a chain link. The shear bolt (16) S"supports the weight of a section of the safety line that depends downwardly from the shear bolt so that, in use, the "weight of the section of the safety line will not inhibit the mobility of the person attached to the safety line. In o the event that the person falls, the shear bolt is designed to shear on account of the person's weight tensioning the oooo• S"safety line.
