Adjustable safety rail barricade for roofs
A post support assembly for an adjustable safety rail barricade is comprised of a universal flat attachment base plate to which a post is secured. The post support has a post connector pivotally connected to a guide bracket. The post connector has an open top end to receive a post therein in a detachably securable fashion. The flat attachment base plate has a pair of opposed side connecting arms disposed on opposed sides of a central connecting arm. At least two spaced-apart incline slots are provided in the side and central connecting arms and are all inclined in a common direction and at a common angle and have a lower open end. The inclined slots in the side connecting arms are spaced apart at predetermined distance. Preferably, but not exclusively, the post support is for a safety rail barricade to be used by roofers.
The present invention relates to a post support assembly for an adjustable safety rail barricade, particularly, but not exclusively, for use by roofers and connected along edges of a roof to provide safety to people working on the roof.
BACKGROUND ARTBarricades of all sorts and particularly rail barricades are well known in the art and these have many uses whereby to restrict entry into particular areas or to provide protection about dangerous spaces such as elevated spaces, namely roofs of tall buildings, observatory platforms, etc. Many of these structures are bulky, difficult to transport, expensive to fabricate and often non stable thereby not offering proper protection. For people working on roofs, such as roofing material installers or roof repair personnel, it is often required that these people be provided with harnesses which are tied with ropes and this makes it difficult for this personnel to displace themselves freely when working on such elevated structures. The harnesses and ropes also provide obstacles to the worker and are often the cause of injury. Therefore, there is a need to provide a safety barricade which is easy to erect, safe, lightweight and easily displaceable.
SUMMARY OF THE INVENTIONIt is a feature of the present invention to provide a post support assembly for an adjustable safety rail barricade which provides the above-mentioned needs and which overcomes several disadvantages of known prior art safety rail barricades.
Another feature of the present invention is to provide a post support assembly for an adjustable safety rail barricade which can be installed along peripheral edges of roofs or elevated platforms.
Another feature of the present invention is to provide a post support assembly for an adjustable safety rail barricade which is lightweight, easy to erect and which is easily displaceable in short periods of time and which provides safety to people working on such elevated surfaces.
Another feature of the present invention is to provide a post support assembly for an adjustable safety rail barricade for use by roofers or other people having to work on elevated surface areas and wherein the post support assembly is adjustable to different pitches of these surfaces.
According to the above features, from a broad aspect, the present invention provides a post support assembly for an adjustable safety rail barricade. The post support assembly is comprised of a universal flat attachment base plate. A post support assembly is secured to the flat attachment base plate. The post support assembly has a post connector pivotally connected to a guide bracket. The post connector has an open top end to receive a post therein. Means is provided to detachably secure the post in the open top end. The flat attachment base plate has a pair of opposed side connecting arms disposed on opposed sides of a central connecting arm. At least two spaced-apart incline slots are provided in each of the side and central connecting arms and are all inclined at a common angle and extend is a common direction. The slots have a lower open end. The inclined slots in the side connecting arms are spaced apart at predetermined distance.
A preferred embodiment of the present invention will now be described with reference to the accompanying drawings in which
Referring now to the drawings and more particularly to

As better seen in
Referring again to
As shown in
As herein shown the post support assembly 11 is connected to the central connecting arm 41 in the apex area with the pair of guide flanges 30 and 30′ extending from the apex area and along a portion of the central connecting arm 41. These guide flanges are welded to the central arm.
As also shown more clearly in
With particular reference now to
It is pointed out that when the attachment base plate 20 is secured to the other side edge 12′ of the pitched roof 13 that the side connecting arm 40′ is the one connected to the roof sheeting. Accordingly to disconnect the base plate 20 an impact has to be applied in the same direction of arrow 55 but this time it extends outwardly of the roof outer side edge 12′ instead of inwardly as shown in
As shown in
Referring now to
As shown in
It is within the ambit of the present invention to cover any obvious modifications over the preferred embodiments described herein, provided such modifications fall within the scope of the appended claims.
