The present invention relates to apparatus for interconnecting wooden members to other wooden members or to concrete.
BACKGROUND
The prior art has seen a number of issued patents and publications relating to bracket devices for interconnecting various structural members, U.S. Pat. No. 7,788,785 to Platt for Method of Connecting a Fence Rail to a Fence Post Using a Rail Clip Assembly and U.S. Pat. No. 10,100,508 to Fox for Rafter Bracket and published U.S. Patent Application No. 2013/0292624 by Bergman for Apparatus and Method for Connecting a Rail or Structural Member to a Post or Other Member are illustrative of such prior art. While these and many other such connection devices have their advantages, it is the primary object of the present invention to provide a modified bracket that will simplify and improve the efficiency of connecting the bottom of a post to a base, such as a concrete footer. The versatility of the present invention also provides increased simplicity in interconnecting wooden structural members.

DETAILED DESCRIPTION OF THE INVENTION
Referring first to FIG. 1, the modified bracket of the present invention is referred to generally by reference numeral 2. An L shaped rigid bracket 4 is illustrated as having an elongated arm 6 and a short arm 8 that are mutually perpendicular. A pair of rigid flanges 10 and 12 are interconnected, as by welding, for example, along their straight edges forming a V shaped structure 15. The welded interconnection of the flanges 10 and 12 forms the base of the V structure. The base of the V structure is welded or otherwise fixedly attached to the upstanding arm 6 of the bracket 4, the attachment being along the longitudinal mid-line of the bracket arm.
The first terminal ends 16 and 18 of the flanges 10 and 12 are straight and are co-planar and are fixedly attached, by welding or other means, to the horizontally disposed arm 8 of the bracket 4.
The second terminal ends 22 and 24 of the flanges 10 and 12 are curvilinear in shape developing into straight longitudinal edges 26 and 28 of the respective flanges 10 and 12.
FIGS. 7-9 illustrate how the modified L shaped bracket 2 anchors a post 30 to a concrete base 32. The horizontally disposed arm 8 of the bracket 4 is attached to the concrete base with bolts 33 that are placed through apertures in the arm 8 and into the concrete base.
Starting at the end of the post that is to be anchored to the concrete base, a first angular mortice 35 is sawed into the flat side of the post, the mortice having a length equal to the length of the V shaped structure 15. A second similar mortice 37 is angularly sawed into the same flat side and positioned so that the open side of the second mortice unites with the open side of the first mortice. The angle between the two mortice channels is the same angle as exists between the flanges 10 and 12 of the V shaped structure 15.
The flanges 10 and 12 are slid into the tight fitting mortice channels until the end of the post is flush against the bolts that anchor the arm 8 of the bracket 4 to the concrete base. Preferably, the mortice channels are filed with epoxy or glue to improve the bond between the post and the flanges. With the post in the proper position on the bracket 4, the elongated arm 6 is bolted or screwed into the side of the post having the mortice channels.
FIGS. 10 and 11 illustrate how the modified bracket 2 can be used to interconnect wooden members, such as a wooden beam 50 and 52, forming the side of a deck structure, and vertical posts 40 that support a handrail. The elongated arm 6 of the L shaped bracket 2 is attached to the structural beam 50, 52 by screws or bolts through apertures in the arm. A post 40 having mortices 47 and 45 is attached to the bracket 2 by inserting the second terminal ends 22 and 24 of the flanges 10 and 12 of the bracket into the respective mortices 47 and 45 and sliding the post down onto the bracket so that the bottom surface of the post is flush against the short arm 8 of the bracket, as seen in FIG. 11. A screw 42 is passed through an aperture in the arm 8 and into the bottom of the post to secure the post vertically on the bracket 2.
