Extendable drip edge

Abstract

The present invention relates to the building structures and more particularly to the drip edge or water leakage guard strip above or below the objects mounted on or into building walls. Such drip edge inhibits the infiltration of water into the building by providing a path for the potentially infiltrating water away from the surface of the building. It is plastic piece with numbered protrusions and guide members. It is easily mountable by nailing between the interior sheathing and the exterior siding wall on the top or on the bottom of the objects mounted on or into the building wall.

1 . Extendable drip edge, adaptable to be positioned above or below objects mounted on or into the building wall, said drip edge included: 
 a base member having a horizontally extendable surface    a vertical wall projecting upwardly from a rear edge of the said base member    protrusions and guide members situated from a back edge to the front edge of said base member    a step of the said base member extending outwardly, obtaining type of interlocking connection of the part from another identical drip edge    a step of the said vertical wall extending outwardly obtaining overlapping type of coupling of the part from another identical drip edge    
   
   
       2 . The extendable drip edge of  claim 1 , wherein the base member sloping downwardly and said base having an essentially rectangular shape  
   
   
       3 . The extendable drip edge of  claim 2 , wherein the base member and the vertical wall form a sloped angle with one another  
   
   
       4 . The extendable drip edge of  claim 1 , wherein a vertical wall extending upwardly from said base member and said wall being provided with openings adaptable to use attachment means for securing to or into a building wall, above or below an object  
   
   
       5 . The extendable drip edge of  claim 4 , wherein a vertical wall has a step extended from its rear end side  
   
   
       6 . The extendable drip edge of  claim 5 , wherein a wall has a peg in an end corner  
   
   
       7 . The extendable drip edge of  claim 6 , wherein a wall has corner side opening to receive peg from another drip edge  
   
   
       8 . The extendable drip edge of  claim 7 , wherein wall has a half round or round peg placed on the end of the opening  
   
   
       9 . The extendable drip edge of  claim 4 , wherein a vertical wall has a step extended from its front end side  
   
   
       10 . The extendable drip edge of  claim 2 , wherein a base member has right end side step  
   
   
       11 . The extendable drip edge of  claim 1 , wherein said upwardly formed protrusions and guide members are disposed on said upper surface on base member on proper distance  
   
   
       12 . The extendable drip edge of  claim 11 , wherein said protrusion and guide member numbers corresponds to the length of the drip edge that can be presented in inches, mm or the like  
   
   
       13 . The extendable drip edge of  claim 12 , wherein said protrusions are presented with at least two types on the base member  
   
   
       14 . The extendable drip edge of  claim 11 , wherein said guide members are presented with at least two types of mating shapes  
   
   
       15 . The extendable drip edge of  claim 12 , wherein one type of protrusions is with straight guide grooves on its rear surface  
   
   
       16 . The extendable drip edge of  claim 12 , wherein second type of protrusions has continuously the same profile along the length of the base member  
   
   
       17 . The extendable drip edge of  claim 14 , wherein projecting portion formed of the wall of the guide member of one extendable drip edge unit is guided from the recessed portion formed on the wall of the guiding groove of second extendable drip edge  
   
   
       18 . The extendable drip edge of  claim 13 , wherein rear surface of the first and second type of protrusions are continuously flat  
   
   
       19 . The extendable drip edge of  claim 13 , wherein shapes of said guide members and straight guide grooves can be different  
   
   
       20 . The extendable drip edge of  claim 17 , wherein strong and reliable engagement between two identical drip edges can be reached with different mating profiles of said guide members and straight guide grooves  
   
   
       21 . The extendable drip edge of  claim 20 , wherein type of overlapping engagement is for extension of the length of the drip edge to match the width of the mounted object  
   
   
       22 . The extendable drip edge of  claim 1 , wherein said edge is adaptable to be positioned above or below objects such as small windows, orifices, junction boxes for electrical and telecommunication connection, receptacles or the like  
   
   
       23 . A method of connecting of the two drip edges comprises of the following steps providing at least one of overlapping members from the base and vertical wall to be connected from identical drip edges, a first projecting portion formed of the wall of the guide member is guided from the recessed portion formed of the guiding groove from the second overlapping member connectable with the first member, inserting the guide member of a base of one drip edge into the straight guide groove of the second member of a base of another drip edge in a direction at an angle to an assembling, wherein at least one guide member of drip edge is guided by at least one guide groove from second drip edge and make strong locking connection  
   
   
       24 . A method of connecting of  claim 23 , wherein disconnection of the strong lock connection is in the reverse way
