Invention Title: Safety guard apparatus
The invention is described in the following statement:
This invention relates to a safety guard apparatus. Depending on the particular embodiment, the apparatus may be suitable for serving the function of a safety rail, hand rail, or the like, for the roof of a portable or temporary building.
Portable buildings are used on construction sites, usually as offices, or for other staffing purposes, such as accommodation, lunch rooms, sick bays, and so on. These buildings are typically transported to the sites on trucks and moved from the trucks into the positions there they will be used, by cranes or similar lifting equipment.
To facilitate such transport and loading and unloading of these buildings, they need to be of a suitably small size. Typical dimensions are in order of 12 m in length by 3 m in width.
On larger construction sites, it is common to join a number of portable buildings together to form a single larger building. The joint between each pair of adjacent buildings where they abut each other needs to be suitably sealed and waterproofed to minimize or prevent the leaking or penetration of water such as rain water, into the buildings. This typically involves applying flashing to the sides and roofs of the two adjacent buildings. This, in turn, requires one or more worker to stand on the roof to carry out such work.
Such buildings have typically included anchor rings attached to the roofs for the securing of workers by attachment of safety harnesses to the rings, to minimise risks of the workers falling from the roofs.
However, safety standards may require more stringent safety measures. For example, in New South Wales, Australia, the rules essentially require that such safety harnesses may only be used if there is no other way to protect workers from falling. Thus, apart from the limited circumstances when there is no other way to provide such protection, what is often required is to provide scaffolding around the buildings, on which workers can stand when applying the flashing and when later removing it after a project is completed and it is desired to remove the buildings from the site.
The erecting of such scaffolding is extremely time-consuming and involves additional costs, and therefore is usually undesirable, especially for smaller projects.
Another option is to use elevated platform vehicles. However, these usually require sufficient space to be available for the vehicles to be driven into position adjacent the buildings, and for the ground surface to be level. These requirements are often not met and therefore, the use of such vehicles is often not feasible. Even in cases where the vehicles can be used, the guard rails of the protected boxes of the platforms of the vehicles typically result in small, awkward spaces in which workers must stand when carrying out the required work.
It is an object of the present invention to overcome or ameliorate disadvantages of the prior art or to provide a useful alternative thereto.

(Continues on Page 7)
Figure 4 is a schematic detailed view of the encircled portion A in Figure 1;
Figure 5 is a schematic detailed view of the encircled portion B in Figure 1; and
Figure 6 is a schematic detailed view of flashing applied at the joint between two building units forming the building of Figure 1.
Referring to the drawings, there is shown in building 10 in the form of a portable shed. The building 10 consists of a number of individual building units 10.1 which are juxtaposed with each other. Each building unit 10.1 has front and rear walls 12 and at least one sidewall 14. At the joints 10.2 between building units 10.1 where they abut each other, the side walls 14 are removed, so that the building units open (lead) into one another.
Each building unit 10.1 and hence the building 10 as a whole has a roof 16. In addition, each building unit 10.1 has connector components 18 in the form of lifting lugs near the lower extremity of the building. These are for the attachment of crane hooks (not shown) for lifting the building units 10.1 to move them from one location to another, for example from a ground surface onto a truck for transport, or vice versa.
In this example, each building unit 10.1 is equipped with air-conditioning units 20 which protrude through the front and rear walls 12, and windows 22 which open out through those same walls, the windows having window frames 22.1 which stand proud of those walls.
The building units 10.1 are equipped with gutters 24 for channelling rainwater running off the roofs 16.
There is provided a safety guard apparatus 30, which includes guard components 32, upper end portions of which constitute safety barrier portions 34 (see Figures 1 and 2), as described further, below.
The guard components 32 are shown in Figure 1 in a partially erected condition, and the following description is in relation to that condition except where otherwise mentioned.
As best seen in Figure 2, each guard component 32 includes two upright members 32.1, and two cross members 32.2 which interconnect the upright members.
In addition, the guard apparatus 30 includes attachment components 36 near the bottom of the guard apparatus. Each attachment component 36 includes a first portion in the form of an upwardly open channel 38, and a second portion 40. The channel 38 includes separate channel portions 38.1 (separate lengths of channel - see Figure 2) secured to the respective building units 10.1, with small gaps 38.2 between the channel portions.
In a preferred embodiment, each second portion 40 is in the form of alength of box iron, with a cut-out portion 40.1, which is adapted to accommodate a respective connector component 18 of a building unit 10.1.
Each piece of box iron 40 is secured to the respective connector component 18 by means of a bolt 41.
Each channel portion 38.1 is connected to two corresponding pieces of box iron 40 by means of hinges 42. Each hinge 42 includes an upper hinge plate 42.1, which is secured to the channel, a lower hinge plate 42.2 which is secured to the box iron, and a hinge pin 42.3 which rotatably connects the upper and lower hinge plates to each other.
Each upright member 32.1 of each guard component 32 is provided with a wheel 46, mounted to a remainder of the respective upright member by means of an axle 48. The wheels 46 are adapted to roll along the insides of the channels 38.
In addition, on each of the upright members 32.1 of one of the two guard components 32, there are provided guide components in the form of an upper and a lower pulley wheel 50, while each of the upright members 32.1 of the other guard component is provided with an upper and a lower connection lug 52.
On each upright member 32.1, there is provided a respective stop component 56 (as best seen in Figure 5) which includes aleg 58 attached to, and extending from, the respective upright member, a stop plate 60 fixed to the leg, and an elongate slider plate 62, attached to the respective stop plate so as to be slidable along the stop plate.
Attached to each box iron 40 of the attachment component 36, immediately adjacent to the corresponding hinge 42, is a stop bracket 66, having a lower wall 66.1 which is bolted to the box iron, and a stop wall 66.2, extending upwardly from the lower wall.
Securement elements in the form of cables 68 are attached to the upper and lower lugs 52 of each upright member 32.1 of the relevant guard component 32. The cables 68 extend over the roof 16, and then partially around the corresponding pulley wheels 50 on the upright members 32.1 of the opposite guard component, before extending downwardly along the respective upright members 32.1 on which the pulley wheels 50 are mounted.
The cables 68 then extend into tighteners in the form of releasable ratchet winches 70 also mounted to the respective upright members 32.1 on which the pulley wheels 50 are mounted. The cables 68 can be of any suitable material such as synthetic rope or steel. While the winches 70 are hand operable, in other embodiments, they may be motorised.
Each winch 70 is provided with a rotatable handle 72.
The assembly and use of the safety guard apparatus 30 in relation to a building 10 will now be described.
As is common on construction sites, a number of portable building units 10.1 are positioned so as to be juxtaposed with each other to form a unitary building 10. Such a building is often used as office space or for other staff purposes for those working on the construction site. It will, however, be appreciated that the invention is not limited to use on a construction site, but may be used in other suitable locations, in especially, but not only, in an outdoor environment.
In order to prevent or minimise the ingress of rainwater into the building 10 when the building units 10.1 are assembled, it is necessary to apply flashing to the front and rear walls 12 and roof 16 of the building units 10.1, at the joints 10.2 between the building units as shown in Figure 6.
According to one example, the flashing includes a rubber sheet S and plastic angle fillets F for establishing seals between the sheets and roofs 16 of the building units 10.1, and which are secured by nails N or other suitable connectors.
Historically, this has required that workers climb up onto the roofs in order to carry out such work, with the inherent risk of the workers falling from the roofs, and injuring themselves.
According to the present invention, the guard apparatus 30 is secured to the building 10 by attaching the attachment components 36 of the guard apparatus 32 to the existing connector components 18 of the individual building units 10.1.
These are useful locations at which to attach the guard apparatus 30 because, typically, these locations of the building units 10.1 are of sufficient strength to allow lifting of the building units by means of cranes or other equipment, which is hooked, or otherwise attached, to the connector components 18.
Once the attachment components 36 of the guard components 32 are secured to the connector components 18 of the building units 10.1, the guard components can be suitably positioned in relation to the attachment components. In order to achieve this, the channels 38 are positioned, by rotating them by means of the hinges 42, so that the open sides of the channels extend forwards or rearwards relative to, and away from, the building 10, preferably in a substantially horizontal direction, or a direction close to the horizontal.
The guard components 32 can then be placed in position relative to the channels 38 by disposing the wheels 46 within the channels. When the guard components 32 are positioned in this manner, they are in a released position, preferably lying prone, with the upper cross members 32.2 being supported on the ground or on supports (not shown) just above the ground.
This operation is carried out at the front and rear sides of the building 10.
Once the guard components 32 are positioned in this manner, one end of each of the cables 68 can be attached to a respective lug 52.
After attachment of the cables 68 in this manner, the opposite, free ends of the cables can be flung by a worker over the roof 16, from the side of the building 10 at which the lugs 52 are disposed, to the opposite side of the building. The free ends can then be passed by a worker around the corresponding pulley wheels 50, and then fed into the winches 70.
Once this occurs, it will be appreciated that rotation of the winch handles 72 will cause the cables 68 to be drawn into the winches 70, thereby decreasing the length of the cables 68 extending over the roof 16, and hence drawing the guard components 32 on the two sides of the building 10 towards each other.
Thus, the guard components 32 are lifted from the prone positions in which they were disposed when the wheels 46 were located within the channels 38, and towards the position as shown in Figure 1.
When the guard components 32 are moved towards the building 10, this causes the channels 38 to rotate by means of the hinges 42 in the direction of the arrows 38.2 (see Figure 1), so that the open sides of the channels face upwards.
Continued rotation of the winch handles 72 will cause the guard components 32 to move closer to each other, thereby drawing them towards the building 10, until the slider plates 62 of the stop components 56 abut against the relevant walls 12 of the building 10. The guard components 32 are then in their operational positions. The tension in the cables 68 causes rotational forces to be applied to the guard components 32 about the stop components 56, urging the wheels 46 outwards relative to the building 10. However, the side walls of the channels 38 retain the wheels 46 in the channels and thus also counter these rotational forces.
The building units 10.1 are of a type of building which is often constructed so as to be light in weight, and therefore not particularly sturdy. It is therefore important that the stop components 56 abut against relatively strong regions of the building 10, so as to prevent damage to the building that might occur due to the force of the cables 68 urging the guard components 32 towards each other. To achieve this, the slider plates 62 can be slid along the stop plates 60, until they are positioned so as to extend across, or in close proximity to, studs 10.3 in the walls 12 of the building units 10.1, as best seen in Figure 2.
It will be appreciated that in order to assemble the guard apparatus 30 and to move the guard components 32 into position as described above, there is typically no need for a worker to climb onto the roof 16 of the building 10.
As a result of the legs 58 of the stop components 56, the guard components 32 are sufficiently spaced from the front and rear walls 12 of the building 10 so as not to interfere with the gutters 24.
In addition, once the guard components 32 are in this erected position with the cables 68 urging the guard components towards the building 10 with the sliders 62 in firm engagement with the building, the safety barrier portions 34 of the guard components 30 - in particular the cross members 32.2 - serve as safety railings for the roof 16, to assist in minimising the chance of a worker who is standing on the roof, from falling from the roof, at the front and rear sides of the building.
The cables 68, under these conditions, will be held taught by the winches 70. Thus, when the cables 68 are spaced from the edges of the building 10 adjacent to the side walls 14, the cables will serve as an obstacle to minimise the chance of a worker on the roof 16 between the guard components 32 walking close to such an edge where the worker may have an increased risk of falling from the roof.
The distance between the upright members 32.1 of each guard component 32 is less than the length of each of the building units 10.1. Therefore, in order for the safety guard apparatus 30 to be used in an effective manner to safeguard workers working on the roof 16 when applying flashing to the roof, it is necessary to move the guard components 32 into suitable positions along the length of the building so as to span the joints 10.2 between adjacent building units 10.1, where the flashing is to be applied. This movement is enabled by the wheels 46, which are free to roll along the channels 38.
In order to effect this, it is necessary to release the cables 68 somewhat from the winches 70 to provide some slack in the cables, so that the stop components 56 move away from the front and rear walls 12 of the building 10. The guard components 32 can be wheeled along the channels 38 by workers supporting the guard components at the front and rear sides of the building 10.
It will be noted that the air conditioning units 20 of the building units 10.1 project some distance from the front and rear walls 12. It is therefore necessary, when moving the guard components 32 past the air conditioning units 20, to provide sufficient slack in the cables 68 to allow the guard components to be moved sufficiently far apart from each other, so that they can move past the air conditioning units, as illustrated in Figure 1.
While the guard components 32 can be maintained in that position by means of workers standing at the front and rear sides of the building 10, the stop brackets 66 provide a means to limit the outward movement of the guard components 32 and hence provide a safety backup, in the event that, say, a worker allows a guard component to move too far from the building or loses grip of the guard component.
Once the guard components 32 have been moved past the air conditioning units 20 (or any other obstacle attached to the building 10), the cables 68 can once again be tightened so as to draw the guard components towards each other and the slider plates 62 into firm engagement with the front and rear walls 12 of the building, so that the safety barrier portions 34 can serve as guard rails, and so that the cables 68 can serve as safety cables, for the roof 16.
In this manner, the guard components 32 can be moved as required so as to be positioned adjacent each of the joints between respective building units 10.1 to allow workers to stand safely on the roofs 16, so as to apply the flashing. The gaps 38.2 between adjacent portions 38.1 of the channels 38 are sufficiently small that the wheels 46 and hence each guard component 32 can roll over those gaps effectively unimpeded, from one channel portion 38.1 to the next.
In order for the workers to climb onto the roofs, aladder can be used.
According to one preferred embodiment of the invention, each guard component 32 is provided with an external worker support basket (not shown) having a side access gate. Workers will be able to climb up to the baskets by means of ladders, to enter the baskets via the gates, and from that position, safely climb over the top cross member 32.2 of the relevant guard component, onto the roof 16.
When it is desired to remove the safety guard apparatus 30 from the building 10, the reverse procedure to that described above for assembling the apparatus can be used. This can be carried out, for example, when it is desired to move the building units 10.1 from the site, onto a truck, or elsewhere on the site.
The upright members 32.1 and cross members 32.2 each include hinges 80 along their lengths to enable rotation of the parts of each member on opposite sides of the respective hinge, relative to each other. In addition, the upright members 32.1 and cross members 32.2 each include suitable locking elements (not shown) having locking conditions for preventing such relative rotation, and released conditions for allowing such relative rotation. The locking elements may, for example, be in the form of rigid sleeves located on the respective upright or cross-members 32.1, 32.2 which are slidable relative to those members into locking conditions in which the sleeves extend over the hinges preventing the relative rotation between the portions of the respective members on opposite sides of the relevant hinges 80, and released conditions in which the sleeves are clear of the hinges.
As a result of the hinges 80, when the safety guard apparatus 30 is removed from a building 10, each of the guard components 32 may be folded into a compact form to facilitate storage and transport.
Although the invention is described above in relation to preferred embodiments, it will be appreciated by those skilled in the art that it is not limited to those embodiments, but may be embodied in many other forms.
For example, the attachment components 36 may be provided with elements other than box iron as described above in terms of the box iron 40.
In addition, embodiments of the invention may be suitable for the attachment components 36 to be connected to connection components on buildings 10 where these connection components are not constituted by pre-existing lifting lugs of the buildings. For instance, such connection components may be purpose-built features for the specific purpose of attaching a safety guard apparatus 30.
