Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to doors, gates, and other closures, and particularly to a receptacle for a gate drop rod that provides an in-ground receptacle for a gate drop rod that is used to secure the center of a double gate when closed.

2. Description of the Related Art

Double-hinged gates, i.e., two gate panels having opposite hinge posts and meeting at a common centerline when closed, are commonly installed across driveways and the like at many businesses, government installations, public parks and recreational areas, manufacturing plants, farms and ranches, and even some residences. Such gates will still swing through a significant arc even when closed and secured together at their common center, unless some means is provided to prevent this movement. This is generally accomplished by means of a “drop rod,” i.e., a vertical rod that passes through two or more retaining hasps attached to one of the gate panels to engage a receptacle in the ground. The second gate secures to the first gate, to prevent movement of both gate panels.

Oftentimes the receptacle provided for the drop rod is no more than an afterthought, and may be formed merely by driving the end of the drop rod into the ground to a depth of an inch or so. While this may be acceptable for a short term, such a makeshift anchor point is rapidly worn away and/or filled with debris, and must be reformed. In other instances, a length of metal pipe may be driven into the ground to serve as a receptacle for the drop rod. Again, such a receptacle may work acceptably for a relatively short period of time, but a short length of pipe of relatively narrow diameter is quick to fill with debris, thereby plugging the hole. Moreover, the installation of such a blind hole, i.e., having no drainage means, tends to trap water in the receptacle. This causes the lower end of the drop rod to rust away over a period of time. If sufficient water is present to fill the hole and that water freezes, it can be a major task to chip the frozen ice away in order to install the drop rod or remove an installed drop rod.

Japanese Patent No. 2007/198,063, published Aug. 9, 2007 shows a receptacle for a drop bar formed by an inner cylinder having a male threaded portion at its lower end that threads into the internally threaded lower portion of an outer cylinder so that the inner cylinder can be removed.

None of the above inventions or patents, taken singly or in combination, shows the present invention as claimed. Thus, a receptacle for a gate drop rod solving the aforementioned problems is desired.

SUMMARY OF THE INVENTION

The receptacle for a gate drop rod is formed of a relatively large plastic canister that is buried in the ground at the site of the drop rod installation. The canister has an open center and bottom for drainage. One or more screened openings may be provided in the lower sides of the canister, if so desired. A plastic cover is secured over the top of the canister, and at least threaded opening is formed through the cover. Preferably, two such openings are formed to provide for drop rods of different diameters. A threaded plastic fitting is installed in the passage to be used, and an end of a length of plastic pipe is threaded into the fitting. Alternatively, the pipe may be threaded directly into the opening in the cover. The unused passage is plugged. In either case, the pipe extends above the cover and the canister.

The hole in the ground into which the canister is placed is lined with relatively large gravel or stones for good drainage. The larger stones are placed about halfway up the side of the canister, with smaller gravel preferably being used for the remainder of the fill. The top of the canister is preferably positioned about two inches below grade. The pipe defining the passage for the drop rod is aligned with the desired location of the rod when the gates are closed. Concrete is poured over the top of the canister to a depth sufficient to provide a level grade with the surrounding surface, with only the plastic pipe of the drop rod receptacle extending to grade at the upper surface of the concrete. Some means of preventing the concrete from adhering to the pipe is preferable (e.g., wax paper or plastic wrap, etc., surrounding the pipe) in order to allow the pipe to be removed and a replacement installed should it become necessary in the future. Preferably, a larger diameter disc of contrasting visibility to the surrounding surface is installed over the upper end of the pipe, to facilitate finding the drop rod receptacle in the dark or in conditions of poor light.

These and other features of the present invention will become readily apparent upon further review of the following specification and drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The receptacle for a gate drop rod comprises various embodiments of an in-ground receptacle for a gate drop rod as conventionally used to secure double gates and the like in the closed position. The receptacle includes sufficient drainage and interior volume to assure that it will not become filled with water or debris and thus limit the insertion of the gate drop rod therein.

FIG. 1 of the drawings provides a side elevation view in section of an exemplary gate drop rod receptacle installation in the ground or earth E. The receptacle 10 includes a relatively large canister 12, as commonly used to protect underground water shutoff valves and the like. The canister 12 has an open bottom 14 to allow complete drainage therefrom, the normally open top 16 being closed by a cover 18. The canister 12 may be frustopyramidal or frustoconical in shape, providing a broad base for the diffusion and drainage of water that may enter through the drop rod passage. Only a single screw or other fastener is shown securing the cover 18 to the upper rim or top 16 of the canister 12, as all of the components of the receptacle 10 assembly will be immovably secured relative to one another once they are installed in the ground and covered.

Additional drainage may be provided adjacent to the bottom 14 of the canister 12 by a drain cutout 20, with the opening of the drain cutout 20 preferably being covered by a reasonably large mesh screen 22 to allow for drainage while preventing the entrance of gravel and/or stone S into the canister 12 during installation of the receptacle. The screen 22 may be loosely secured over the outside of the drain cutout 20, e.g., tape, etc. prior to installing the receptacle 10 in the ground, as the pressure of the surrounding stone S will hold the screen 22 in place on the canister 12 after installation of the receptacle.

The cover 18 includes at least one, and preferably two, threaded openings formed therethrough. The two openings 24a and 24b are of different diameters from one another in order to allow the installation of different diameter drop rod pipes, e.g., pipe 26, therein, depending upon the diameter of the gate drop rod with which the receptacle 10 is to be used. In the example of FIG. 1, the smaller diameter first opening 24a has the end of a pipe 26 of corresponding diameter installed therein, with the opposite unused larger diameter opening 24b being closed by a cooperating cap or plug 28. The two openings 24a and 24b are preferably internally threaded. The cooperating pipe 26 and cap or plug 28 are each provided with cooperating external threads. For this purpose, the pipe 26 has a threaded stud extending from one end that either engages one of the openings 24a, 24b directly (as shown in FIG. 1), or engages a threaded adapter (as shown in FIG. 3) installed in the opening 24a, 24b, so that the body of the pipe 26 extends above the cover 18 and the canister 12, the canister 12 serving as a pier or base to support the pipe 26. While it is envisioned that both the pipe 26 and cap 28 are permanently installed, it may be necessary to remove and replace the pipe 26 after some prolonged period of use. Accordingly, the pipe 26 may be protected from contact with the surrounding concrete C during installation to allow it to be unthreaded from its passage 24a and a new pipe installed as a replacement, if necessary.

The pipe 26 serves as a closely fitting sleeve for the gate drop rod, thus greatly reducing lateral play of the drop rod within the drop rod pipe 26, The pipe 26 is completely open at both its upper and lower ends 30a and 30b, to allow any moisture, debris, etc. to drop completely through the pipe 26 and into the large interior volume of the canister 12 below. Water and other moisture dissipate through the open bottom of the canister 12, and into the underlying stone and gravel S, and thence into the ground or earth E below. The open upper end 30a of the pipe 26 is preferably positioned just above grade, with a high visibility guide 32, e.g., a disc of contrasting color and/or high reflectivity and/or phosphorescence, etc., being secured (e.g., interference fit) about the upper end 30a of the pipe 26 and in contact with the underlying surface.

The drop rod receptacle 10 is installed by first digging a hole at the desired location, with the hole being somewhat larger than the dimensions of the receptacle 12. Preferably, a relatively large or coarse grade of stone S is placed in the bottom of the hole to a depth on the order of a couple of inches, more or less, as desired. The canister 12 is then placed in the hole atop the layer of stone S therein, with the cover 18 and drop rod pipe 26 in place on the canister 12. The canister 12 may be adjusted slightly, as desired, to align the pipe 26 with the drop rod of the gate by swinging the gate to the desired position and lowering the drop rod to indicate the exact position required for the receptacle 10.

Once the exact position of the receptacle 10 has been set, more stone S is placed in the hole to surround the lower portion of the canister 12. A finer grade of gravel or stone S2 is then placed about the upper portion of the canister 12, generally about up to the cover 18. Normally, the cover 18 of the canister 12 is about two inches (more or less, as desired) below grade at this point. The area atop the canister cover 18 and surrounding gravel or stone S2 is then filled with concrete C, to bring the upper surface up to grade. The upper end 30a of the pipe 26 may be trimmed as needed at this point, leaving only a slight amount (e.g., ¼ A inch or so) extending above the surface of the concrete C. The high visibility disc 32 is then forced over the upper end 30a of the drop rod pipe 26, to complete the installation.

FIG. 2 provides an illustration of an exemplary completed installation. In this above-ground view, the only portions of the receptacle that are visible, are the upper end 30a of the drop rod pipe and the surrounding high visibility disc 32. The two gates G1 and G2 are shown closed in this view, with the drop rod D lowered into the drop rod pipe to secure the two gates in their closed positions.

FIG. 3 of the drawings is an illustration of all of the components of a kit for assembling and installing the receptacle 10. It will be understood that not all of the components will be installed in any given installation, but various components of different diameters are provided in the kit to allow the installer to choose the desired components according to the diameter of the gate drop rod for which the receptacle 10 is to be installed.

The kit for the gate drop rod receptacle 10 includes the canister 12 with its precut lower drain cutout 20 (one or more) and installed screen 22. The cover 18 is also included, with its two previously formed and threaded drop rod passages 24a and 24b. One or more fasteners 34 may be provided for securing the cover 18 to the upper rim or top 16 of the canister 12, although the cover 18 need only be secured to the canister 12 sufficiently to prevent its being dislodged during installation of the receptacle, i.e., the pour of concrete over the cover 18. Accordingly, two drop rod pipes 26a and 26b are provided with the kit. Each of the pipes has a threaded lower end cooperating with the corresponding opening 24a and 24b of the cover 18. It should be noted that the two pipes 26a, 26b shown in FIG. 2 may be provided in somewhat longer lengths to allow the receptacle to be buried more deeply, if so desired, with the unused portion of the installed pipe 26a or 26b being cut off after installation.

Alternatively, a pair of intermediate adapters or fittings, respectively 36a and 36b, may be provided in the kit if so desired. These adapters or fittings 36a and 36b are installed in the corresponding threaded openings 24a and 24b of the cover 18, and the pipe to be used, either the smaller diameter pipe 26a or the larger diameter pipe 26b, is installed in the corresponding adapter or fitting 36a or 36b, as desired. It will be noted that when an adapter 36a, 36b is used, the openings 24a, 24b need not be threaded, but may be smooth bore openings, and the adapters 36a, 36b may be secured to the cover 18 by PVC cement or the like, the adapters being internally threaded to receive the corresponding pipe 26a, 26b. The opposite unused opening 24a or 24b, or the adapter or fitting 24a or 34b installed therein, is closed by means of a corresponding cap or plug 28a or 28b. Finally, a pair of high visibility discs 32a and 32b are provided with the kit. The only difference between the two discs 32a, 32b is the size of the central passage therein, the disc 32a having a smaller passage for fitting tightly about the smaller diameter drop rod pipe 26a and the disc 32b having a larger diameter passage to fit tightly about the larger diameter pipe 26b.

Accordingly, the receptacle 10 for a gate drop rod greatly improves the operation of a gate drop rod in securing a gate so equipped. The drainage provided by the open bottomed canister 12, and its relatively large interior volume, likely assure proper drainage of water or other liquid that may pass through the drop rod pipe 26 for years after installation. Any minor debris, e.g., leaves, pine needles, dirt, etc., that falls through the pipe 26 will be collected within the large interior volume of the canister 12, with it again being likely that this will not pose a problem for many years after installation. Preferably the various components, i.e., the canister 12, top 18, pipes 26a and 26b, caps or plugs 28a and 28b, fittings 36a and 36b (if provided with the kit), and the discs 32a and 32b, are all formed of a durable plastic material in order to prevent corrosion from the moisture accompanying the in-ground installation of the receptacle. Accordingly, the receptacle 10 for a gate drop rod in its various embodiments will likely serve well for many years, and may outlast the gates and gate installation.
