The invention relates generally to fencing, gates, and gate hardware, and more particularly to a system for adjusting gates.
There are many known types of gates. They vary across a wide spectrum of forms, shapes, sizes, etc. Nevertheless, a standard gate will generally be rectangular in shape and have two primary vertical components (a hinge side and a latch side) and two primary horizontal components (an upper edge and a lower edge). The hinge side is usually attached by one or more hinges to a fence, building, vertical post, etc. (hereafter, a “hinge post”). The hinges allow the gate to swing in an arc relative to the hinge post, usually through approximately ninety degrees of travel (although often up to one hundred and eighty degrees or more).
Opposite the hinge side is the latch side of the gate. As its name implies, the latch side usually has some type of latch attached thereto that allows the gate to be secured in a closed position. The latch side of a standard gate closes against or in proximity to an upright post or similar vertical surface (hereafter, a “latch post”). When properly installed, a uniform gap is left between the latch side of the gate and the upright latch post so that the gate can open and close easily without some portion of the latch side rubbing or catching on some portion of the latch post. This gap is called a latch post gap.
Running horizontally between the hinge side and the latch side (and generally perpendicular thereto) are the upper and lowers edges of the gate. These components form the main structure of the gate and determine the overall length of the gate. Together, the two edges and two sides form the rectangular shape that defines most standard gates. Such gates can be commonly found, for example, on fences surrounding residential properties. Of course, there are many other shapes and forms for gates and the present invention is applicable to many more types than just a standard gate.
Regardless of the particular type of gate, there is one more or less ubiquitous problem that any given gate will, almost invariably, suffer eventually: gate sag. Gate sag usually occurs because of the force of gravity acting on the gate. As gravity slowly pulls down the latch side, the hinge side usually stays generally in place because it is attached to a supporting structure by the hinges. Thus, the rectangle that previously defined the shape of the gate becomes deformed as the angles between the sides and the edges are forced out of ninety degrees. As the latch side continues to be drawn downwards by gravity, the latch post gap narrows and one portion (usually the upper end) of the latch side begins to contact the latch post. Over time, the contact can be become quite extreme, such that the gate is difficult to open and almost impossible to close, as the latch side no longer fits inside the latch post.
A number of devices are known in the art that attempt to address this problem. One common device uses a support wire that extends from the top of the hinge post across to the latch side of the gate. The support wire is under tension such that the latch side is supported and should not sag, in theory, under the affects of gravity. However, not only does the support wire often fail to completely forestall gate sag, it also disrupts the aesthetic appearance and look of the gate. Additionally, it can be extremely difficult to retro-fit an existing gate with a support wire once the gate begins to sag. Another device known in the art uses an adjustable tension gate bracket (see U.S. Pat. No. 6,751,906 to Bass). This device suffers from similar deficiencies as the support wire mentioned above. Other external support structures, such as the chain device disclosed by Harris in U.S. Pat. No. 4,468,888, are also known but suffer similar problems.
Thus, there remains a need for a gate adjustment system that can prevent, correct, or otherwise mitigate gate sag and can reduce the force or effort necessary to close a gate which has already sagged.
One embodiment of the present invention is a gate adjustment system comprising a bull-nose glide, a flat glide, a plurality of spacers, a gap size gauge, and a gap adjustment wedge. The two glides are attached to the latch post and the latch side of the gate opposite one another. Either glide can be attached to either location, but it is preferable to attach the bull-nose glide to the latch side of the gate. A preferred attachment location is near the top of the latch side, preferably above the latch itself. The glides are positioned so that as the gate is shut, the bull-nose portion of the bull-nose glide impacts the rounded edge of the flat glide. The two curved surfaces allow the impact force to be spread out and cause the gate to be lifted and pushed back towards the hinge side and into alignment.
The gap adjustment wedge is used during the initial installation procedure. With the gate closed, the gap adjustment wedge is positioned between the top of the latch side and the latch post—the gate can be lifted and the gap adjustment wedge pushed deeper into the gate gap until the gap is uniform from the top to the bottom. Once a uniform gap measurement is achieved, the gap size gauge should be employed. This device is placed within the gap and is used to compare the size of the gap compared to a plurality of known measurements. In another embodiment, other means of measuring the gap can be used.
Before removing the gap adjustment wedge, a straight, horizontal line can be drawn across both the latch side and the latch post in order to indicate the desired location for installation of the glides. The wedge can be removed and the gate at least partially opened so that the inner surfaces of both the latch side and latch post can be accessed for installation of the glides. Either glide can be installed on either the latch post or the latch side. Installation involves securing the glides to the latch post and latch side so that the rounded bull-nose of the bull-nose glide impacts the rounded edge of the flat glide as the gate is swung shut. As the two rounded surfaces come together, they slide over one another and cause the gate to be lifted and pushed such that the latch side fits within the gate opening and a constant latch post gap is produced. As the gate comes to rest in the appropriate position, the two glides are resting against one another. If the latch post gap that was previously measured is larger than the width of the two glides then one or more spacers can be placed between the glide(s) and the latch post/latch side during installation, as necessary.
If the present invention is installed on a new gate or on a gate that has not yet begun to suffer from gate sag, the contact between the two glides will be minimal during the gate closing procedure. However, once closed, the glides will be in contact in order to take the stresses off of the hinges and the gate itself and thereby keep gate sag from developing. Therefore, a goal of the present invention is to forestall the development of gate sag in new or otherwise solid gates. Another goal of the present invention is to allow gates that have already begun to succumb to gate sag to be more easily closed and to forestall further deterioration.
The aforementioned and other features and objects of the present invention and the manner of attaining them will become more apparent and the invention itself will be best understood by reference to the following descriptions of a preferred embodiment and other embodiments taken in conjunction with the accompanying drawings, wherein:
Referring now to the drawings, exemplary embodiments of the invention are described below in the accompanying Figures. The following detailed description provides a comprehensive review of the drawings in order to provide a thorough understanding of, and an enabling description for, these embodiments. One having ordinary skill in the art will understand that the invention may be practiced without certain details. In other instances, well-known structures and functions have not been shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.
The bull-nose glide 110 has a curved, bull-nose portion 112 and a first mounting block portion 114. The broken-line rectangle labeled “112” surrounds and defines the curved, bull-nose portion 112. The curved, bull-nose portion 112 is shaped so as to distribute the impact forces when the gate is closed and redirect those forces into lifting and pushing the gate back into alignment rather than just having the latch side of the gate impact, and likely bounce off of, the latch post.
The approximately ninety degree angled portion of the bull-nose portion 112 is designed to wrap around the inside and back face of the latch side of a gate. Alternatively, the angled portion can be wrapped around the inside and front face of the latch post. In either case, the majority of the bull-nose portion 112 resides outside of the gate gap (i.e., the space between the latch side of the gate and the upright latch post) when the gate is closed.
The broken-line rectangle labeled “114” surrounds and defines the first mounting block portion 114 of the bull-nose glide 110. The first mounting block portion 114 is placed against either the inside of the latch post or the inside of the latch side and affixed thereto. When the gate is closed, the first mounting block portion 114 resides within the gate gap. Exemplary placement of the bull-nose glide 110 on a gate assembly can be seen in
Operating in concert with the bull-nose glide 110 is the flat glide 120. The flat glide 120 has a curved portion 122 and a second mounting block portion 124. The broken-line rectangle labeled “122” surrounds and defines the curved, portion 122. The curved portion 122 is shaped so as to distribute the impact forces when the gate is closed and redirect those forces into lifting and pushing the gate back into alignment rather than just having the latch side of the gate impact, and likely bounce off of, the latch post.
The broken-line rectangle labeled “124” surrounds and defines the second mounting block portion 124 of the flat glide 120. The second mounting block portion 124 is placed against either the inside of the latch post or the inside of the latch side and affixed thereto. Exemplary placement of the flat glide 120 on a gate assembly can be seen in

The curved portion 222 is shaped so as to distribute the impact forces when the gate is closed and redirect those forces into lifting and pushing the gate back into alignment rather than just having the latch side of the gate impact, and likely bounce off of, the latch post.
The broken-line rectangle labeled “224” surrounds and defines the second mounting block portion 224 of the flat glide 220. The second mounting block portion 224 is placed against either the inside of the latch post or the inside of the latch side and affixed thereto. Exemplary placement of the flat glide 220 on a gate assembly can be seen in

As illustrated in the embodiment in
In some installations, it is contemplated that the gap size may be less than one half inch. If this is the case, the posts, gate and/or hinges may need to be adjusted in order to increase the gap to one half inch or more. Alternatively, either or both of the latch side of the gate or the latch post can have material removed therefrom in order to accommodate the system components therebetween.
It is to be understood that the system can be embodied in various sizes having various dimensions besides those shown in the accompanying figures. For example, the system could be built for 2×4 gates, 4×4 gates, 2×6 gates, smaller gates, larger gates, etc. Furthermore, although
Installation of the system can be performed on older gates that have already experienced gate sag, those that may yet experience gate sage, new gates, etc. The system can be incorporated into new gate materials so that it is built into a gate as the gate is constructed or it can be added at a later time. The gate adjustment system components can be made out of a variety of materials and are not limited to any specific materials or group of materials. Possible examples of materials include, but are not limited to: injection molded plastic, high impact materials, impact resistant materials, low friction materials, outdoor application long-life materials (e.g., ozone resistant, high/low temperature-variation resistant, water resistant, UV resistant, etc.), materials having combinations of features, etc.
