This invention relates to a set of brackets for constructing a wooden gate.
Corner gate brackets can be used to frame right angle joints between structural members of a gate at each of four corners. Such gate brackets are meant to provide a reliable guide for the positioning of the structural members to assist the do-it-yourself handy man. In addition, corner gate brackets are meant to minimize or eliminate the distortion of the gate structure over time.
Gate brackets are typically made of metal so as to resist bending and to ensure a rigid structure. Typically, a gate bracket comprises elongate flat metal members arranged in perpendicular relationship so as to guide the formation of a right angle between the pieces of structural lumber which are made to abut the elongate members. An example of such a system is disclosed in Boroviak, U.S. Pat. No. 6,896,244.
Parallel elongate flat metal members may be provided in a spaced relationship for bracketing structural lumber on two opposed sides and to provide a perpendicular arrangement of such elongate members. Such a system is disclosed in Cosgrove, U.S. Design Patent No. D410,835. In Cosgrove, each pair of parallel elongate flat metal members form a U-shape and the two U-shaped pairs are welded together to form the overall bracket.
To provide structural rigidity for gate brackets, typically either a brace member is provided, as in Boroviak, or relatively thick metal members are provided, as in Cosgrove. In Boroviak, the diagonal brace member is welded to each of the perpendicular elongate metal members, which are in turn welded together at the intersection.
It is an object of the present invention to provide a structural gate bracket that serves to effectively frame a right angle between structural pieces, such as 2×4 pieces of lumber, while maintaining the structural relationship of the joint, over time, and at the same time not providing undue weight to the gate bracket, avoiding overly thick metal elements or excessive welding.
This and other objects of the invention will be better understood with reference to the detailed description of the invention which follows.
According to the invention, there is provided a web extending in a plane. A first pair of perpendicular elongate portions are provided normal to the plane of the web, preferably along two edges of the web. A second pair of perpendicular elongate portions are provided normal to the plane of the web in spaced parallel relationship to the first pair.
In another aspect of the invention, each pair of elongate portions comprises flanges of said web.
In a further aspect, an opening is provided in said web member between the first and second pairs of elongate portions.
In a further aspect, the opening extends between a first pair of parallel first and second members and between a second pair of parallel first and second members thereby defining a substantially L-shaped opening.
In another aspect, the invention comprises a web extending in perpendicular directions in a plane, said web including a first flange extending normal to said plane parallel to a first one of said directions, a second flange extending normal to said plane parallel to a second one of said directions in an end-to-end perpendicular, abutting relationship to said first flange. The web has an outer perimeter, an opening extending in generally perpendicular directions within said perimeter, a third flange normal to said plane along an edge of said opening and in spaced relationship to said first flange and a fourth flange normal to said plane along an edge of said opening and in spaced relationship to said second flange.
In another aspect, the invention comprises a method of forming a gate bracket comprising:
The foregoing was intended as a broad summary only and of only some of the aspects of the invention. It was not intended to define the limits or requirements of the invention. Other aspects of the invention will be appreciated by reference to the detailed description of the invention and to the claims.
The invention will be described by reference to the detailed description of the invention and to the drawings thereof in which:
Throughout the following description specific details are set out to provide a more thorough understanding of the invention. However, the invention may be practiced without these particulars. In other instances, well known elements have not been shown or described in detail to avoid unnecessarily obscuring the present invention. Accordingly, the description and drawings are to be regarded in an illustrative, rather than a restrictive, sense.
Referring to
Web 12 has a generally L-shaped opening 18 that extends in perpendicular directions parallel to directions 14 and 16. Opening 18 is spaced inwardly from the perimeter 20 of the web 12.
A first flange 22 extends normal to the plane of the web 12 along a perimetral edge 24 of web 12, parallel to direction 14. A second flange 26 extends normal to the plane of the web 12 along a perimetral edge 28 of web 12, parallel to direction 16. First 22 and second 26 flanges are in abutting perpendicular relationship to one another.
A third flange 30 extends normal to the plane of the web 12 along an edge 32 of opening 18. Third flange 30 extends parallel to first flange 22 and in spaced relationship therewith.
A fourth flange 34 extends normal to the plane of the web 12 along an edge 36 of opening 18. Third 30 and fourth 34 flanges are in abutting perpendicular relationship to one another.
The spacing between first 22 and third 30 flanges is selected so as to correspond to the dimensions of structural pieces (such as lumber, plastic or metal), to be used in the gate system, as is the spacing between second 26 and fourth 34 flanges.
One end of each of the third and fourth flanges may optionally be further bent away from opening 18 as at 38, 40 in order to provide additional structure rigidity to the flanges.
A hinge 42 may be provided on selected brackets according to whether the bracket will be used on the hinge side of the gate to be constructed.
One advantage of the first embodiment of the invention is that the entire structure, save for the attachment of a hinge, may be formed from a single flat sheet of materials, as will be described by reference to
There is first provided a web 12 as shown in
An elongated rectangular portion 30 is bent from the plane of the web so as to be normal to it and an elongated rectangular portion 34 is bent from the plane of the web so as to be normal to it to form flanges 30 and 34.
Short end portions 29, 31 of flanges 30, 34 may then be bent along lines 33, 35 so as to be normal to flanges 30, 34 to provide structural rigidity to flanges 30, 34.
An elongated rectangular portion 22 along edge 25 of web 12 is bent so as to form a flange 22 that is normal to the plane of the web 12. An elongated rectangular portion 26 along edge 27 of web 12 is bent so as to form a flange 26 that is normal to the plane of the web 12. Once bent, flanges 22 and 26 are in abutting perpendicular relationship and flanges 30, 34 are in abutting perpendicular relationship, as seen in

A fourth embodiment 80 is shown in
In a method of assembly of a gate or door, four brackets as described above, may be used in the construction of a gate. Two brackets placed on adjacent corners may have hinges, whereas the two other brackets may not have hinges. Structural pieces, such as lumber, plastic or metal members may be used in the assembly of the gate. Typically four structural pieces of lumber (or equivalent) will be used to create a gate frame in a square or rectangular formation. Gate face structural members, such as 2×4 pieces of lumber, can then be secured to the gate frame to complete the gate. As understood in the art, the face structural members could be attached to one side of the gate frame, on both sides, or having face structural members in an alternating pattern with structural members secured to opposing sides of the gate frame.
Many other variations or additional features can be practiced in accordance with this invention. For example, a structural brace 66 could be added between flanges 30 and 34. The structural brace would help maintain the structural integrity of the corner of the gate. The structural brace could be placed at any suitable angle, such as 45 degrees from each of flanges 30 and 34.
Portions 64 of web 12 could be punched out, cut out, or otherwise removed from the structure without departing from the scope of the invention. Cutting out portions 64 of web 12 could be of any desired shape and location and would reduce the amount of material, such as metal, and reduce the weight of the gate bracket.
In certain embodiments, reinforcing lines 62 could be used to add structural integrity to the metal. Reinforcing lines 62 could be depressions formed on one side of the metal, with a corresponding protrusion on the opposite side of the metal. To maximize effectiveness of the reinforcing lines 62, the lines may be linear. Reinforcing lines 62 could be added to web 12 or flanges 30 and 31.
It will be appreciated by those skilled in the art that the first and second embodiments have been described above in some detail but that certain modifications may be practiced without departing from the principles of the invention.
