Description

CONSTRUCTION SAFETY SYSTEM
FIELD OF THE INVENTION

The present invention relates to a construction safety system, and more particularly, relates to construction safety system for installation on the peak of a sloped roof to reduce the likelihood of falling from the sloped roof during construction and/or repairs.

BACKGROUND OF THE INVENTION
Construction safety is an important part of any construction job, particularly when serious injury or death may result when insufficient efforts are made to reduce the risks to a construction worker. When working at a height off of the ground, for example, when building or shingling a sloped roof, it is important to have safety systems and tools which are easy to install, easy to use, and easy to uninstall, and which significantly reduce the likelihood that a construction worker working on the roof will fall from the roof and be injured, or killed.

United States Design Patent No. 254,534 (Glynn et. al) discloses a device which is designed to be nailed over the peak of a sloped roof, providing an anchor point for the attachment of a safety rope. However, while installing and/or uninstalling this device, the worker installing or uninstalling this device needs to be physically present on the roof (to nail the device to the roof, or to un-nail it from the roof when finished) remains unprotected from a fall during the installation and/or deinstallation processes. Furthermore, as this device is nailed to the roof, the device needs to be physically removed from the roof when finished, thereby potentially damaging the roof, or alternatively, hiding the device by shingling over it, a less than satisfactory solution.
It is desirable to have a safety device and system that reduces the likelihood that a construction worker working on the roof will fall from the roof and be injured, or killed, that is easy to install, easy to use, and easy to uninstall, that does not leave the worker unprotected during installation and uninstallation, and that does not damage the roof and can be fully removed from the roof when the work has been completed.

Another object of the present invention is to provide a safety device and system that is easy to install on a roof, easy to use, and easy to uninstall from the roof when the work is completed.
Another object of the present invention is to provide a safety device and system that does not leave the worker unprotected during installation and uninstallation of the safety device and system.

Another object of the present invention is to provide a safety device and system that does not damage the roof and can be fully removed from the roof when the work has been completed.
According to one aspect of the present invention, there is provided a construction safety device for temporarily mounting on two opposing surfaces of a peaked roof, comprising, a first arm adapted to contact a first surface of the roof and adapted to receive a first length of tie-down rope, a second arm in pivotable engagement with the first arm, adapted to contact a second surface of the roof and adapted to securely receive a safety line and a second length of tie-down rope, a third arm, in pivotable engagement with the first arm adapted to securely receive a length of release rope means for releasable engagement of the third arm from the second arm; wherein when the third arm is engaged with the second arm, the first arm, second arm and third arm form a bracket for mounting on the roof of the building and being securable thereto by the lengths of tie-down rope and securely supporting the safety line, and wherein the release rope is pulled, the third arm is disengaged from the second arm, allowing the first arm to pivot relative to the second arm and allowing the bracket to be dismounted from the roof.

An advantage of the present invention is that it provides a a safety device and system that reduces the likelihood that a construction worker working on a roof will fall from the roof and be injured, or killed.

Page 2 of 7 A further advantage of the present invention is that it provides a safety device and system that is easy to install on a roof, easy to use, and easy to uninstall from the roof when the work is completed.

In a preferred embodiment of the present invention, as illustrated in Figures 1, 2 and 3, a safety bracket, generally shown as 2, is provided, and adapted for temporary installation straddling a peak of a sloped roof 3, having, in a preferred embodiment, a first arm 4, preferably made of a length of angle aluminum as illustrated in Figure 4A (for example, the length being up to a meter or more in length, it being understood that alternative materials and material configurations may alternatively used as would be understood by a person skilled in the art), the first arm 4 having a lower hole 6 therein, adapted to securely and temporarily receive a length of tie-down rope 8 or a shackle (not shown) or other similar device to which the tie-down rope 8A is securely attached as illustrated in Figure 2, which tie-down rope 8A is to be secured to the ground or building to provide a tie-down for the bracket as more fully described herein.

In the preferred embodiment of the present invention, a second arm 20 is provided preferably made of a length of angle aluminum as illustrated in Figure 4B (for example, the length being up to a meter or more in length, it being understood that alternative materials and material configurations may alternatively used as would be understood by a person skilled in the art), the second arm 20 having a lower hole 22 therein, adapted to securely and temporarily receive a second length of tie-down rope 8B or a shackle (not shown) or other similar device to which the second rope 24 is securely attached as illustrated in Figure 2, which tie down rope 8B is to be secured to the ground or building to provide a tie-down for the bracket as more fully described herein. An additional lower hole 23 is provided into which hole a safety line 62 is inserted, to be used by the worker as needed (for example, to be attached to a safety harness or other fall arrest device in a manner known to a person skilled in the art).
In the preferred embodiment of the present invention, a third arm 40 is provided preferably made of a length of flat aluminum bar as illustrated in Figure 4C (for example, the length being up to a meter or more in length, it being understood that alternative materials and material configurations may alternatively used as would be understood by a person skilled in the art), the third arm 40 having an outer hole 42 therein, adapted to securely and temporarily receive a length of release rope 44 or a shackle (not shown) or other similar device to which the release rope 44 is securely attached as illustrated in Figure 2, which release rope is available to the worker as a release line Page 4 of 7 as more fully described herein. In the preferred embodiment of the present invention, the third arm 40 has a series of openings 50 therein adapted to receive a bolt or pin 52 which has been bolted or otherwise securely fastened (by means of a nut 53, for example) to the second arm, which bolt or pin 52 preferably has an enlarged head 54, an embodiment of which bolt or pin 52 is illustrated in Figure 4D, which illustrates a magnified view of one end of the second arm illustrated in Figure 4B.

In the preferred embodiment of the present invention, the first arm 4 is securely and pivotably engaged with the second arm 20, preferably by way of corresponding holes 30 and 32 respectively in the first arm and second arm, through which holes 30 and 32 a pivot bolt 28 or other similar device is securely positioned, to allow the first arm and second arm to pivot relative to one another (as illustrated by the arrow 25 in Figure 3) so that the bracket can be adapted for use on roofs of a wide range of different pitches. In this embodiment of the present invention, the first arm 4 is also securely and pivotably engaged with the third arm 40, preferably by way of corresponding holes 46 and 48 respectively in the first arm and third arm, through which holes 46 and 48 a pivot bolt 50 or other similar device is securely positioned, to allow the first arm and third arm to pivot relative to one another (as illustrated by the arrow 53 in Figure 3) so that the bracket can be engaged and released as hereinafter described.

Prior to installing the bracket of the present invention on a roof, tie-down ropes are attached to the first and second arms, a release line is attached to the third arm and a safety line 62 is attached to the additional lower hole 23 in the second arm. Also prior to installing the bracket on the roof, the angle between the first arm and second arm is adjusted (by pivoting the first arm about the pivot bolt 28 relative to the second arm) to correspond to the relative angle of the corresponding surfaces of the roof onto which the device is to be positioned, and thereafter locking this angle into place by inserting the bolt or pin 52 into the appropriate opening 50 in the third arm (it being understood that in an alternative embodiment of the present invention, the adjustment and securement of the angle between the first arm and second arm can be done after the bracket is temporarily positioned on the peak of the roof and prior to final positioning thereon). Thereafter, the device of the present invention is positioned at the highest point on the roof (preferably by throwing one end of one of the tie-down ropes over the peak of the roof and down the other side (with or without the use of a piece of extension twine as needed) and Page 5 of 7 thereafter pulling this rope from the other side until the bracket is positioned at the roof's peak), the first and second arms extending over the top of and downwardly on opposite sides of the roof, straddling the peak. The tie-down ropes attached to the first and second arms are thereafter secured to the ground or building to securely position the bracket in location on the roof. The safety line 62 may then be attached to the worker or the worker's harness in a conventional manner, the length of the safety line being adjustable relative to the worker or the worker's harness in a conventional manner to secure the worker relative to the bracket and the roof. When the bracket is no longer needed, it may be removed from the roof, by gentling tugging on the release line to rotate the third arm so that the bolt or pin 52 is no longer engaged with the opening 50, allowing the bracket to be removed from the roof by disconnecting one of the tie-down ropes on one side of the roof, and in a controlled manner releasing that tie-down rope in step wise fashion, while allowing the bracket to be pulled down the other side of the roof by way of the tie-down rope on that other side of the roof until the bracket safely reaches the ground on that other side of the roof.
The present invention has been described herein with regard to preferred embodiments. However, it will be obvious to persons skilled in the art that a number of variations and modifications can be made without departing from the scope of the invention as described herein.
