Apparatus For Preventing Birds Accessing a Habitable Part of a Structure

Abstract

Apparatus ( 2 ) for preventing buds ( 4 ) accessing a habitable part ( 6 ) of a structure ( 8 ), which apparatus ( 2 ) comprises barrier means ( 10 ) for preventing the birds ( 4 ) accessing the habitable part ( 6 ) of the structure ( 8 ), and securing means ( 12 ) for securing the barrier means ( 10 ) to the structure ( 8 ), characterised in that the barrier means ( 10 ) comprises a plurality of barrier bars ( 14 ) which are arranged side by side, a first connecting bar (16) which is connected to a first part ( 18 ) of the barrier bars ( 14 ), and a second connecting bar ( 20 ) which is connected to a second part ( 22 ) of the barrier bars ( 14 ), the barrier bars ( 14 ) being such that they are spaced apart by a distance which prevents the birds ( 4 ) getting between the barrier bars ( 14 ), the barrier bars ( 14 ) being such that in use they extend both vertically and inwardly towards the structure ( 8 ) in order to be ale to extend over and cover the width of the habitable part ( 6 ) of the structure ( 8 ), and the barrier bars ( 14 ) being such that in use they extend vertically sufficiently steeply to prevent the birds ( 4 ) remaining on the barrier bars ( 14 ).

1 . Apparatus for preventing birds accessing a habitable part of a structure, which apparatus comprises barrier means for preventing the birds accessing the habitable part of the structure, and securing means for securing the barrier means to the structure, characterized in that the barrier means comprises a plurality of barrier bars which are arranged side by side, a first connecting bar which is connected to a first part of the barrier bars, and a second connecting bar which is connected to a second part of the barrier bars, the barrier bars being such that they are spaced apart by a distance which prevents the birds getting between the barrier bars, the barrier bars being such that in use they extend both vertically and inwardly towards the structure in order to be able to extend over and cover the width of the habitable part of the structure, and the barrier bars being such that in use they extend vertically sufficiently steeply to prevent the birds remaining on the barrier bars. 
     
     
         2 . Apparatus according to  claim 1  in which the barrier bars are of a small cross sectional size in order to make it difficult for birds to perch on the barrier bars. 
     
     
         3 . Apparatus according to  claim 1  in which the barrier bars are each cranked to form a sloping portion which slopes at an angle which is less than 90° but which causes the sloping portion to slope too steeply for the birds to remain on the sloping portion. 
     
     
         4 . Apparatus according to  claim 3  in which the barrier bars are each cranked to form the sloping portion and a vertical portion, the sloping portion extending from the firs connecting bar downwardly to the vertical portion, and the vertical portion extending downwardly towards the second connecting bar. 
     
     
         5 . Apparatus according to  claim 4  in which the vertical portion extends into a horizontal portion which is connected to the second connecting bar. 
     
     
         6 . Apparatus according to  claim 1  in which the barrier bars are spaced apart by a distance of 10-100 mm. 
     
     
         7 . Apparatus according to  claim 1  in which the barrier bars are welded to the first and second connecting bars. 
     
     
         8 . Apparatus according to  claim 1  in which the securing means secures the barrier means to the structure such that the barrier means is able to be moved for maintenance purposes. 
     
     
         9 . Apparatus according to  claim 8  in which the securing means secures to the habitable part of the structure. 
     
     
         10 . Apparatus according to  claim 9  in which the securing means is a clamp. 
     
     
         11 . Apparatus according to  claim 8  in which the securing means secures to a part of the structure other than the habitable part. 
     
     
         12 . Apparatus according to  claim 11  in which the securing means is a pivotable securing means so that the barrier means is able to be pivoted between a closed position for preventing the birds accessing the habitable part of the structure, and an open position for permitting access for maintenance purposes. 
     
     
         13 . Apparatus according to  claim 1  and including auxiliary securing means for securing the apparatus in position in the event of a failure of part of the structure. 
     
     
         14 . Apparatus according to  claim 13  in which the auxiliary securing means comprises a cable. 
     
     
         15 . Apparatus according to  claim 1  and including a spacer material on a face of the second connecting bar that is adjacent the structure, the spacer material being such as to prevent any long term adverse chemical reaction between the material of the second connecting bar and the material of the structure. 
     
     
         16 . A structure when provided with apparatus according  claim 1 .
