SUMMARY OF THE INVENTION
The present invention relates to an alternative configuration of adjustable base bracket for securing a scaffolding post on a roof.
According to the present invention there is provided an adjustable base bracket for roof scaffolding post which includes a base adapted to be secured to roof trusses having a width sufficient to span at least two roof trusses. The base has a leading edge intended to be positioned upslope on a pitched roof and a trailing edge.

The body has a first end oriented toward the leading edge of the base and a second end. The pivot axis is positioned at the first end of the body. A receptacle positioned on the body which is adapted to receive a scaffolding post.
These and other features of the invention will become more apparent from the following description in which reference is made to the appended drawings, the drawings are for the purpose of illustration only and are not intended to in any way limit the scope of the invention to the particular embodiment or embodiments shown, wherein:
3 0 FIGURE 1 is a top plan view of an adjustable base bracket constructed in accordance with the teachings of the present invention.
FIGURE 2 is a side elevation view of the adjustable base bracket illustrated in FIGURE 1 positioned for use on an angled surface.
FIGURE 3 is a side elevation view of the adjustable base bracket illustrated in FIGURE 1 positioned for use on a flat surface.

DETAILED DESCRIPTION OF THE PREFERRED EIdIBODIMENT
The preferred embodiment, an adjustable base bracket for a roof scaffolding post generally identified by reference numeral 10, will now be described with reference to FIGURES 1 through 4.
Structure and Relationship of Parts:
Referring to FIGURE 1, adjustable base bracket 10 includes a base 12 adapted to be secured to roof trusses by a series of nail receiving openings 14. Either nails or screws may be inserted into nail receiving openings 14. Base 12 is wider than it is long.
The width of base 12 is sufficient to span at least two roof trusses. Base 12 has a leading edge 16 intended to be positioned upslope on a pitched roof, and a trailing edge 18. Referring to FIGURE 2, an elongate body 20, which has a first end 24 oriented toward leading edge 16 of base 12 and a second end 26 is pivotally mounted to base 12 for pivotal movement about a substantially 2 0 horizontal pivot axis 22 which is positioned at first end 24 of body 20. A
support leg 28 is used to support body 20 in a selected pivotal position. Support leg 28 is pivotally mounted to, and depending, from second end 26 of body 20. There are a series of slotted support receivers 30 on base 12 for locking support leg 28 in a selected angular position. In the illustrated embodiment, support leg 28 is locked in the selected position by inserting a pin 29 into one of 2 5 the slotted support receivers 30. Refernng to FIGURE 4, pin 29 is attached to support leg 28 and is in the direction of the width of base 12. Referring again to FIGURE 2, there is also a receptacle 32 adapted to receive a scaffolding post positioned on body 20. In FIGURE 2, support leg 28 is locked in a position in a slotted support receiver 30 such that body 20 is horizontal and receptacle 32 is vertical, while base 12 is at an angle, and in FIGURE 3, 3 0 locking support leg is locked in a position in a slotted support receiver such that body 20 and base 12 are each in a horizontal position, with receptacle 32 in a perpendicular position in relation to the base, thereby facilitating use on a flat roof.
Operation:
'The use of adjustable base bracket 10 will now be discussed with reference to FIGURES 1 through 4. Adjustable base bracket is placed on a roof such that base 12 spans at least two roof trusses, and such that leading edge 16 is positioned upslope on a pitched roof, or if the roof is flat, in any convenient orientation. Base 12 is then secured by putting nails through nail receiving openings 14 and into the roof trusses. First end 24 of body 12 is then pivoted about horizontal pivot axis 22, and support leg 28 is pivoted about second end 26 of body 20. Support leg 28 is locked in a position by inserting pin 29 into one of the slotted support receivers 30 such that body 20 is horizontal and receptacle 32 is vertical. The slotted support receiver 30 that is chosen will depend upon the pitch of the roof.
Adjustable base bracket 10 is removed by removing the nails from nail receiving openings 14.
Advantages:
The present invention provides a number of advantages over the Cupp reference and the Goodwin et al reference:
- The base has a width that extends between two or more roof trusses and, therefore, provides a more secure mode of attachment to the roof.
- The body can be locked in a selected pivotal position, in order to place the receptacle 2 0 in a desired angular orientation. This is in contrast to the Cupp reference and the Goodwin et al reference in which the receptacles pivoted freely.
- Rapid adjustment is possible by merely repositioning the support leg in a different one of the series of slotted support receivers.
- The adjustable base bracket can also be used on a flat roof, as there is included an 2 5 adjustment that places the receptacle in an orientation perpendicular to the base.
In this patent document, the word "comprising" is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article "a" does not exclude the 3 0 possibility that more than one of the element is present, unless the context clearly requires that there be one and only one of the elements.
