Encapsulating Post Base

BACKGROUND OF THE INVENTION

[0001]This invention relates to a one-piece, rigid connector for connecting an upright supported member to a supporting structure, in particular a connector for attaching a structural post to a concrete foundation or footing. The connector has particular utility in building gazebos, trellises, pergolas and other outdoor shade structures where the post should be attached to the foundation, and the structure itself provides some lateral resistance bracing for the post.

[0002]There are a number of such patents to connectors for attaching uprights to their pads or foundations to resist lateral and overturning loads.

[0003]U.S. Pat. No. 4,096,677 teaches a rigid connector for connecting a supported structural member to a supporting structural member where the connector is partially embedded in the foundation or concrete footing.

[0004]U.S. Pat. No. 5,333,435 teaches a connector for connecting a supported structural member to a supporting structural member where the connector is not embedded in, but rather rests upon the supporting structural member or foundation.

[0005]U.S. Pat. No. 5,568,909 teaches a connector for connecting a supported structural member to a supporting structural member where the connector fully encompasses the post or supported member and the connector is bolted to the ground with a threaded member.

[0006]U.S. Pat. No. 11,072,940 teaches a connection where the post is fully encapsulated by the connector and the connector is partially embedded in the foundation.

[0007]US Design Patent D610,717 teaches a post base that fully encapsulates the post it connects to the supporting structural member. The connector is formed with outwardly directed bottom flanges which receive threaded fasteners that are driven into the foundation or pad.

[0008]The present invention finds particular use when the designer has decided that they do not want to embed the base of the posts in the ground or the foundation, and similarly do not want to embed the connector in the foundation. Although, the present invention can also be used to connect a post or supported member that is partially embedded in the foundation or supporting member to the supporting member.

SUMMARY OF THE INVENTION

[0009]The present invention provides a one-piece, sheet metal connector that connects a supported member or post to a supporting member to resist upload and overturning forces that is economical to produce and easy to install.

[0010]The present invention allows the base of the post or supported member to rest on the top of the concrete foundation or footing.

[0011]The present invention also provides a connector that encapsulates the post to help resist lateral loading.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0023]As shown in FIG. 1, the present invention is a connection made with a connector 1 that connects to a supported structural member or post 2. The post or supported structural member 2 has a base 3, a front face 4, a back face 5, and first and second side faces 6 and 7. The base 3, front face 4, back face 5 and the first and second side faces 6 and 7 are preferably substantially planar.

[0024]The connector 1 connects the supported structural member 2 to a supporting structural member 8. The supporting structure 8 is typically, at least partially embedded in the ground and made from concrete. The supporting structure 8 is typically a foundation, footing or pad. The supporting structural member could also be partially built from wooden structural members such as deck or floor platform. Decks and floor platforms are typically attached to a concrete foundation or footing set below them. The supporting structure 8 has a support surface 9 that is generally flat.

[0025]The connector 1 is preferably made by taking a piece of sheet steel and using cold-forming processes to cut, punch, bend and shape the sheet member into a final three-dimensional form.

[0026]The connector 1 has a front member 14 and a back member 15. The front member 14 is a substantially planar member. When the connector 1 is used in the connection at least a portion of the front member 14 is in registration with the front face 4 of the post 2. The connector 1 also has a first side member 16 connected to the front member 14, and the first side member 16 extends from the front member 14 at an angle thereto. Preferably the first side member 16 extends from the front member 14 at an orthogonal angle such that the first side member 16 has a at least a portion that partially interfaces with the first side face 6 of a post 2 made with four side faces set at orthogonal angles to each other. The first side member 16 connects to the back member 15. When the connection is formed, the first back member 15 has a portion that at least partially interfaces with the back face 5 of the post 2. The connector 1 also has second side member 17 connected to the back member 13, and the second side member 17 extends from the back member 15 at an angle thereto. Preferably the second side member 17 extends from the back member 15 at an orthogonal angle such that the second side member 17 has a portion that at least partially interfaces with the second side face 7 of a post 2 made with four side faces set at orthogonal angles to each other that is sized to be closely received between both the first and second side members 16 and 17 of the connector 1 and the front and back member 14 and 15 of the connector 1. The first and second side members 16 and 17 are preferably substantially planar members.

The connector 1 also has a first foot flange 26 connected to the first side member 26 and disposed at an angle thereto. Preferably the first foot flange 26 is disposed at an orthogonal angle to the first side member 16 and extends away from the post 2. The connector 1 also has a second foot flange 27 connected to the second side member 17 and disposed at an angle thereto.

When the connector 1 has been formed into its final shape, the free side edge 80 is disposed adjacent to or in close association with the second side bend 36 along the second side edge 37 of the second side member 17. Preferably, the bottom edge 42 of the front member 14 starts at the free side edge 80 and extends most of the width of the front member 14 until it meets with an upwardly extending notch 81 in the material that makes up the front member 14 and the stand-off member 70. The front member 14 also has a lower edge 82 that extends from the first side bend 30 to the notch 81. The lower edge 82 of the front member 14 is preferably placed at a similar height as the bottom edges 44, 46, 48 and 50 of the back member 15, the first and second side members 16 and 17 and the overlapping flange 18.

The openings 94 in the front member 14 and the overlapping flange 18 overlap each other such they will receive the same fastenings 90 through both openings 94. The openings 94 in the front member 14 are preferably formed as enlarged slots to allow for some play between the front member 14 and the overlapping flange 18 when the connection is formed. The other openings are formed as round openings.

[0041]The foot member 25, 26, 27, and 28 are also preferably formed with a plurality of openings 96.
