LADDER SAFETY DEVICE

FIELD OF INVENTION

The present invention relates to a safety device for use with ladders, and in particular, but not exclusively, to a safety device for use with ladders used to access an elevated advertising billboard.

BACKGROUND OF INVENTION

1,adders are used in numerous applications where access to elevated positions is required. For example, ladders may be used to provide access to roofs, windows, gutters, elevated wall surfaces, ceilings, storage racking or shelving or the like. Various forms of ladder are available; a familiar form consisting of two elongate members aligned parallel to each other and joined together by a plurality of rungs or steps distributed along their lengths. In use, such a ladder may extend from the ground or other suitable surface and rest against an elevated object such as a wall, roof edge or window ledge or the like. There are various dangers, some potentially fatal, associated with using ladders, the most obvious being the possibility of a ladder slipping or collapsing when in use, resulting in a fall of a user. _ A

4; .

- One particular use of ladders is for access to billboards and the like which are used to display advertisements in the form of posters, placards or electronic displays, for example, and which may be secured to the sides of buildings or alternatively may be supported by dedicated frames or structures. Ladders may be utilised during the replacement or renewal of advertisements or during maintenance of the billboard or alternatively of any lighting units, for example, associated with the billboard. Due to the fact that most billboards are located in elevated positions and are relatively large, access usually requires the use of long ladders, and the worker may be tempted to stretch beyond the safe limits of the particular ladder being used to remove an old or hang a new advertisement, which may cause the ladder to topple.

To protect a worker from a possible fall when using a ladder, or to arrest a fall of a worker from a ladder, it is known in the art for the worker to be secured via a fixed connection to an anchor point located on the structure against which the ladder rests. In this way, if the ladder were to slip or if a worker should lose balance and fall from the ladder, the fall would be arrested by the fixed connection and anchor point. The fixed connection may be a lanyard or the like secured between a worker's safety harness and the anchor point.

41 a, ., , l,, : ..e While such a fixed connection may provide adequate protection for a worker in the event of a fall, the connection may restrict the movement afforded to the worker and may require the worker to constantly disconnect from one anchor point and reconnect to another anchor point every time the ladder is to be moved to a new location. Disconnecting and reconnecting to a fixed anchor point in this manner is not only time consuming, but requires that the worker lacks any form of protection from a fall for those periods where they are disconnected from the anchor. Furthermore, such fixed connections may, in some cases, only be set up when the worker has ascended the ladder to a specific height such that no protection is provided during the ascent and descent of the ladder.

It is an object of the present invention to provide a safety device and system which may be utilised with ladders and which obviates or at least mitigates the aforementioned and other problems with the prior art.

SUMMARY OF INVENTION

According to a first aspect of the present invention, there is provided a safety device for use with a ladder, said device comprising an elongate body which, in use, is located in proximity to and aligned relative .e a C .e.

DETAILED DESCRIPTION OF THE DRAWINGS

Reference is first made to Figure 1 in which there is shown a ladder safety device 10 located above a billboard 12. Billboards, such as that shown in Figure 1 display adverts and the like in the form of, for example, ... * e. 8 # *as.

8 8 a a 8 . . ' 868 a posters which are fixed using an adhesive paste, to the billboard, by a worker. Due to the fact that the billboard 12 is located in an elevated position and due to the large area of the billboard 12, a worker, in order to reach the entire surface of the billboard 12, may require the use a ladder. Additionally, maintenance of the billboard 12 and of any associated components such as a lighting rail 14 may require the use of a ladder. This may therefore expose a worker to the danger of a fall, for example by the ladder toppling or collapsing, or by the worker slipping or losing balance while on the ladder. The safety device 10 of the present invention is provided to offer protection to a worker when using a ladder, as discussed in detail below.

Reference is now made to Figure 2 in which there is shown a perspective view, from above, of a portion of the safety device 10. The device 10 includes an elongate body or guard rail 16 secured to a ladder support member or rail 18 by a plurality of brackets 20. The elongate guard rail 16 is laterally spaced from and aligned parallel with the ladder support rail 18, and the ends of each rail 16, 18 are secured by a linking element 21 (only one shown) to provide added support for the elongate guard rail 16 an improve the rigidity of the device 10. Mounted on the ladder support rail 18 are a number of protection elements 22 which are distributed . e e t. 8 along the length of the support rail 18 and extend laterally therefrom in a direction generally towards the elongate guard rail 16. The safety device 10 is secured to a wall 24 by way of an elongated bracket 26, wherein the elongated bracket 26 is fixed to the wall 24, and the safety device 10 is secured to the elongate bracket 26.

As shown in the embodiment of Figure 2, the safety device further includes a plurality of spacer members 28 (only one shown) fixed to the ladder support rail 18, wherein these spacer members 28 are secured to the elongate bracket 26 by respective clamping brackets 30.

The safety device 10 is shown in use in Figure 3 of the drawings. As shown, the device 10 is located above a billboard 12 and a ladder 32 is positioned between the rails 16, 18, and is rested against the ladder support rail 18 between adjacent protection elements 22. Thus, if the ladder 32 is titled outward, unintentionally or otherwise, away from the billboard 12, the extent by which the ladder 32 may be displaced from the support rail 18 will be restricted by eventual contact with the elongate guard rail 16. Additionally, if the ladder is tilted or slides along the support rail 18, its displacement will be restricted by the protection elements 22. Thus, any movement of the ladder 32 once positioned with the safety device 10 will be restricted, . e. . . . . . . ..

consequently minimising the possibility of the ladder 32 tipping and possibly toppling over.

Referring to Figure 4, there is shown an perspective view of an end portion of the safety device 10, wherein an anchor 34 is provided secured to the elongate rail 16, wherein the anchor 34 provides a safety point to which a worker may attach when working at an elevated location.

A perspective view, from below, of a portion of the safety device 10 is shown in Figure 5. As shown, the elongate rail 16 defines a track 36 within which the anchor 34 is slidably mounted. Thus, the anchor 34 may be translated along the length of the elongate guard rail 16 by sliding along the track 36. A safety line inertia block assembly 38 is provided and is coupled to the anchor 34, wherein the inertia block assembly 38 houses a retractable safety line 40, to which safety line 40 a worker may secure a harness. The use of a retractable line 40 allows a worker to move relative to the anchor 34 and safety device 10 while any slack or redundant line is retracted into the inertia block assembly 38.

Additionally, the retractable safety line 40 and inertia block assembly 38 in combination with the fact that the anchor 34 is translatable along the length of the elongate guard rail 16, allows a worker relative freedom to undertake the required duties while remaining secured to the anchor 34. For example, a worker may descend a . . . . . . . . ...

ladder located between the elongate rail 16 and ladder support rail 18, move the ladder to a different location between the rails 16, 18, and ascend the ladder in its new position to continue the required activities, all while remaining secured to the safety line 40 and anchor 34.

The inertia block assembly 38 causes the retractable safety line 40 to be locked to prevent further extension of the line 40 in the event of a fall of a worker secured to the line. Thus, the inertia block assembly 38 will provide protection against and arrest a fall irrespective of how much safety line is extended from the inertia block assembly.

A cross-sectional view of the safety device 10 is shown in Figure 6. As shown, the elongate rail 16 is of a general box section defining a longitudinal slot 42 on the underside thereof for receiving a portion of the anchor 34. The anchor 34 is translatable along the length of the elongate rail 16 by way of a pair of rollers 44 which rollably engage an inner surface of the rail 16 on either side of the slot 42. In the embodiment shown, the anchor 34 is mounted on a shaft or spindle 46 extending between the rollers 44.

A preferred feature of the present invention is shown in Figure 7, wherein a portion of the safety device is located above a billboard 12. Located remote from . * . . e e e eve e e e e e e e e e e ee e e ee. e e.e e the safety device 10 is a safety line retention unit 48 to which unit 48 the retractable safety line 40, when extended from the inertia block assembly 38, is secured to maintain access to the safety line 40. Thus, the retention unit 48 is secured at a height which is safely accessible to a worker without requiring the use of a ladder, such that a worker may secure the retractable safety line 40 to a harness prior to ascending a ladder to carry out duties at a greater elevation.

It should be understood that the embodiments hereinbefore described are merely exemplary of the present invention and that various modifications may be made thereto without departing from the scope of the invention. For example, the safety device 10 shown in the drawings is used adjacent to a billboard 12 to provide a degree of safety when a worker accesses the billboard with a ladder. However, the safety device may be located in any elevated position where access by ladder is required for whatever reason. The safety device 10 may be secured directly to the billboard 12.

Additionally, a worker may attach a safety line directly to the anchor point, eliminating the inertia block assembly.
