FIELD OF THE INVENTIONThis disclosure generally relates to pipe systems, and more particularly, to a pipe connector and system therefor.
BACKGROUND OF THE INVENTIONIrrigation is the artificial application of water to the land and is often used in the growing of crops and maintaining landscapes. Subsurface irrigation systems are often preferred because they conceal the irrigation lines so as not to adversely affect the aesthetics of the property or real estate being irrigated. However, access to the irrigation lines in order to perform repairs is limited because the irrigation lines are located underground. In order to replace a part of the irrigation line, such as a valve or cracked piping, the ground typically needs to be dug up about 3-4 feet beyond and 3-4 feet behind the repair site. This is because the subsurface irrigation lines are only slightly maneuverable and usually are not flexible enough to be bent upwardly in order to properly connect the ends of the replacement parts to the ends of the pre-existing irrigation line. Furthermore, if the part that requires replacement is the irrigation valve, the irrigation valve may not only be underground, but it may also be housed within an irrigation box which makes the irrigation valve even harder to access.
SUMMARY OF THE INVENTIONThis summary is provided to introduce a selection of concepts in a simplified form that are further described below in the DESCRIPTION OF THE APPLICATION. This summary is not intended to identify key features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
In accordance with one embodiment of the present invention, a connector is disclosed. The connector comprises a male portion having a center channel passing therethrough and having a dovetail tenon; a female portion having a center channel passing therethrough and a dovetail mortise adapted to mate with the dovetail tenon; and a gasket positioned between the male portion and the female portion.
In accordance with another embodiment of the present invention, a connector for use in a pipe system is disclosed. The connector comprises a male portion comprising: a face; a tubular body extending perpendicularly from a rear surface of the face wherein the tubular body is adapted to connect the male portion to the pipe system; a dovetail tenon integral with a front surface of the face; and a center channel passing through the male portion; a female portion comprising: a face; a tubular body extending perpendicularly from a rear surface of the face wherein the tubular body is adapted to connect the female portion to the pipe system; a dovetail mortise recessed within a front surface of the face and adapted to mate with the dovetail tenon; a center channel passing through the female portion; and a circular gasket positioned between the male portion and the female portion.
In accordance with another embodiment of the present invention, a water pipe system is disclosed. The water pipe system water pipe system comprises piping; and at least one water pipe connector used to couple one pipe system component to another pipe system component, the pipe connector comprising: a male portion comprising: a face; a V-shaped dovetail tenon integral with a front surface of the face; a tubular body extending perpendicularly from a rear surface of the face, wherein the tubular body is adapted to couple the male portion to one pipe system component; and a center channel passing through the male portion; a female portion comprising: a face; a V-shaped dovetail mortise recessed within a front surface of the face and adapted to mate with the dovetail tenon; a tubular body extending perpendicularly from a rear surface of the face, wherein the tubular body is adapted to couple the female portion to the other system component; a center channel passing through the female portion; and a circular groove surrounding an opening of the center channel; and a circular gasket held within the circular groove.
In its simplest form, the pipe connector 10 may comprise a male portion 12 and a female portion 32. Referring to
As shown in
It should be clearly understood that the male portion 12 of the pipe connector 10 have more than two faces 14; for example, the male portion 12 may have three faces 14 arranged in a configuration so that it may function as a pipe T-intersection or it may have four faces 14 arranged in a cross-configuration so that it may function as a four-way pipe intersection. The male portion 12 of the pipe connector 10 may have any number of suitable faces 14 in any suitable configuration.

A=Radius of center channel
B=Width of the space between the perimeter of the opening on the face of the female portion and the outer perimeter of the circular groove)
C=O-ring size
D=Clearance for the O-ring
E=Width of Adjacent Side
Gage Point=A+B+C+D+E
Specifically, in the example provided above, the gage point 102 would be calculated as follows:
Gage Point=0.50 in.+0.100 in.+0.139 in.+0.050 in.+0.125 in.+0.914 in.
In order to determine the width of the adjacent side 53 to the angle α formed between the side surface 50 and the face 34 of the female portion 32 (the E variable in the equation above), one may consider the measurement of the opposite angle β from the angle α formed by the side surface 50 of the mortise 52 and the front surface 36 of the face 34 of the female portion 32 and also consider the thickness (depth) of the mortise 52. For example, where the mortise 52 has a thickness (depth) of 0.25 in. and where the side surface 50 of the mortise 52 forms a 45° angle α with the front surface 36 of the face 34 of the female portion 32, the opposite angle β would be 45° (assuming that the rounded edge/radii 51 of the side surface 50 forms, a 90° angle with the front surface 36 of the face 34 of the female portion 32). The width of the adjacent side 53 to the angle α formed between the side surface 50 and the face 34 of the female portion 32 (variable E) may be calculated according to the following formula where:
E=Width of the adjacent side to angle α
β=Opposite Angle
X=Thickness of the mortise
E=tan β×(½ X)
Specifically, in the example provided above, the width of the adjacent side 53 to the angle α formed between the side surface 50 and the face 34 of the female portion (variable E) would be calculated as follows:
E=tan 45°×½(0.25 in.)=0.125 in.
The gage point 102 for each of the side surfaces 50 of the female portion 32 would therefore be located 0.914 in. from the center point of the opening 40 of the center channel 48 and 0.125 inches down the side surface 50 of the mortise 52 (i.e. half the thickness/depth of the mortise 52). Once the gage point 102 for the female portion 32 has been determined, the same gage point 102 may be used for the male portion 12 having a tenon 30 with the same dimensions as the mortise 52. For example, the gage point 102 for the corresponding male portion 12 would be located 0.914 in. from the center point of the opening 20 of the center channel 26 and 0.125 inches high on the tenon 30 (i.e. half the thickness of the tenon 30).
As described herein, the pipe connector 10 of the present invention may be coupled to any point in a pipe system. As described herein, the pipe connector 10 may be coupled to any point of an irrigation system. For example, as shown in
A new irrigation valve 100 may then be fitted with two male portions 12 (see
As mentioned above, the pipe connector 10 of the present invention may be used to replace any faulty part of the irrigation line that may require replacement. The faulty part would be replaced as similarly described above, wherein the irrigation line is cut, a female portion 32 of the pipe connector 10 is coupled to each of the cut ends of the piping, a male portion 12 of the pipe connector 10 is coupled to each end of the replacement part, and the male portions 12 and corresponding female portions 32 are coupled together so that the tenons 30 of the male portions 12 engage the mortises 52 of the female portions 32 to form water-tight connections between the replacement part and the piping. In still another embodiment, the male portions 12 of the pipe connectors 10 may be integral to the connection points of the replacement part (e.g. check valve, four-way pipe intersection, pipe T-intersection, straight piping, etc.).
