The invention relates to the field of structural bracing and in particular gate brackets for use in building a door for a gate.
When building a structure such as a gate door, different structural members are brought together and fastened into position at joints. This has led to the proliferation of many different designs and constructions of structural joints. Whether the joint is constructed using temporary measures such as screws or a more permanent one such as welding or gluing, the end result is the connection of two structural elements at a joint.
Depending on the type of joint, different limitations prevail. These include lack of strength and difficulty of construction. For the most part, temporary joints tend to be weaker than the permanent ones, but are easier to make.
This has led to the development of hardware brackets for joining and retaining wood pieces or other structural members at joints. For example, U.S. Design Pat. No. 410,835 discloses a set of two U-shaped elements that are welded together such that they are perpendicular to one another. A hinge is welded across the joint between the two U-shaped elements. While the gate bracket taught in the '835 design patent is easy to use and provides rigidity to the joints, it suffers from several drawbacks. Locating the hinge across the joint between the elements requires careful welding first of the elements in order to ensure a flat surface upon which to attach the hinge, and of the hinge itself. In addition, because each element comprises a three-sided bracket within which to place a wood piece, a substantial amount of metal is used in this design.
Canadian Industrial Design No. 83050 discloses first and second straight elongated flat rectangular members at right angles to one another. A rectangular hinge is attached at right angles to the end of a short extension of the first member. An additional cross-brace member extending between the rectangular members provides additional support. But because the hinge is connected edge-wise to the end of one of the rectangular members, its connection is a weak one and of limited strength. The hinge requires very careful welding in order to ensure that it is attached perpendicular to the brace member and may be damaged should it inadvertently come into contact with another object. In addition, apart from the weld, the hinge is supported only by direct connection with the lumber used to frame the gate.
Accordingly, a need exists for an improved joint bracket construction providing ease in construction and high strength and which overcomes the defects noted above.
According to the present invention there is provided a connector or gate bracket for rigidly joining two adjacent structural members at a joint comprising a flat elongated first member having a first and a second ends, a flat elongated second member extending in one direction from, and perpendicular to, the first member, from the first end of the first member, a flat elongated third member extending from the first member in spaced parallel relationship with the second member, and an angular cross brace extending between the first and the third members.
In another aspect, the cross brace defines a 45 degree angle in relation to the first member and in relation to the third member.
In yet another aspect of the invention, the connector further comprises a hinge secured to the second member in face to face relationship. The hinge may be secured to the second member by welding.
In yet another aspect of the invention, the cross brace is secured to the first member between the second end of the first member and the third member and is secured to the third member between a free end of the third member and the first member.
In yet a further aspect, a plurality of holes are located in each of the first, second and third members.
In yet another aspect, the second and third members are the same length.
In yet another aspect, the first member is longer than the second and third members.
In yet another aspect, the second member is spaced from the third member a distance equal to a standard width of cut lumber.
Other aspects of the invention will be appreciated by reference to the detailed description of the preferred embodiment and to the claims that follow.
These and other features of the invention will become more apparent from the following description in which reference is made to the appended drawings and wherein:
The preferred embodiment of a set of gate brackets 10 is illustrated in
A set of four connectors such as gate brackets 12, 14, 16, 18 may be used to join structural elements, such as lumber pieces 2 shown in phantom, so as to form a frame for a door or the like. Bracket 12 is a mirror image of bracket 14, while bracket 18 is a mirror image of bracket 16.
As shown in
A method of using the brackets 12, 14, 16, 18 in association with 2×4 lumber to build a gate door will now be described. Top and bottom 2×4's are cut one inch shorter than the width of the proposed gate opening. Elongated first members 20 are attached to the 2×4's with suitable fasteners, preferably screws, inserted through holes 28. The top and bottom 2×4's are positioned so that second members 22 extend past the ends of the respective 2×4's as shown in
Left and right 2×4's are cut to an appropriate length to define the height of the gate door. The left and right 2×4's are positioned within the spaces between second and third members of the respective brackets. The space between the second and third members 22, 24 is selected to snugly accommodate the lumber 2. Once again, suitable fasteners are inserted through holes 28 and 32 in order to attach the left and right 2×4's to the brackets: Further lumber may then be connected to the top, bottom, left and right 2×4's to complete the gate door. Hinges 30 are attached, preferably by screws to a structural member of a fence in order to connect the gate door to the fence.
It will be appreciated by those skilled in the art that the preferred and alternative embodiments have been described in some detail but that certain modifications may be practiced without departing from the principles of the invention.
This application is a continuation of U.S. application Ser. No. 10/265,226 filed Oct. 7, 2002, entitled GATE BRACKET.
