PIPE CONNECTORS AND USES THEREOF

FIELD OF THE INVENTION

BACKGROUND OF THE INVENTION

The agriculture market and needs are constantly changing. Recent challenges are associated with the requirement to increase agriculture yields while decreasing consumption of natural resources and minimizing environmental damages. The water shortage prevailing in many countries as well as global warming and shortage in other resources yielded new attempts to provide innovative irrigation technologies that would be cost effective and efficient.

US patent application No. 2011/0220238 discloses joints for use in pipe systems carrying pressured fluids. The pipes provided with integrally formed male spigot end and a female socket end. Joints are made using the pipes provided with integral male and female ends. The joints are formed by inserting the male spigot of one pipe into the female socket of another pipe.

CN205534712 discloses an outlet connecting device comprising: a card bearing sleeve in communication with card quick connect conduit between the bearing sleeve and the snap-in card. US patent application No. 2006/0006643 discloses a connector having a frusto- conical front member and a recessed elongated cylindrical land with a plurality of barbs for coupling to a tube. The frusto -conical member includes a first barb that engages with the inner surface of the tube and the elongated cylindrical land defines a space that provides a sealing area which acts like a lock and traps the walls of the tube to aid in both the perfection of a seal between the tube and the connector and increases the pull-off resistance of the connector.

There is a need in novel agriculture irrigation devices and systems that would be user friendly, and allow an efficient, and cost-effective irrigation.

In one or more embodiments, the material used to manufacture the connectors comprise a polymeric material. Various types of polymeric materials are suitable, for example, the polymeric material may be polypropylene.

In one or more embodiments, the inner diameter of the herein disclosed connectors may be substantially constant along the entire length thereof. In an embodiment of the invention, the inner diameter may be variable presenting a reduced diameter towards first connector end or towards second connector end. The diameter in accordance with this embodiment, is continuously reduced along the length of the connectors towards first connector end or towards second connector end. The diameter in accordance with this embodiment, may be reduced along the length of the connectors towards first connector end or towards second connector end by up to about 30%. For example, up to about 25% or up to about 20%, up to about 15%, or up to about 10%. The inner diameter may thus present a conical shape with a cut-off end being first connector end or second connector end. In an exemplary embodiment, the inner diameter is reduced towards second end. In an exemplary embodiment, the inner diameter may be about 30 mm to about 90 mm. For example, about 40 mm to about 80 mm, about 40 mm to about 70 mm, about 40 mm to about 60 mm, or about 30 mm to about 60 mm. In one exemplary embodiment, the inner diameter may be about 48 mm, or about 50 mm, or about 55 mm.

In one or more embodiments, the outer diameter of first portion is substantially similar, or similar to the outer diameter of second portion. In one or more embodiments, the outer diameter of the herein disclosed connectors may be substantially constant along the entire length thereof. In an embodiment of the invention, the outer diameter may be variable presenting a reduced diameter towards first connector end or towards second connector end. The diameter in accordance with this embodiment, is continuously reduced along the length of the connectors towards first connector end or towards second connector end.

In an exemplary embodiment, the outer diameter may be about 30 mm to about 100 mm. For example, about 40 mm to about 90 mm, about 40 mm to about 80 mm, about 40 mm to about 70 mm, about 40 mm to about 60 mm, or about 30 mm to about 60 mm. In an exemplary embodiment, the outer diameter of the tube may be about 50 mm, or about 55 mm .

In an embodiment of the invention, first portion may have a length of about 30 mm to about 70 mm. For example, about 30 mm to about 60 mm, about 40 mm to about 55 mm, or about 45 mm to about 55 mm. In an embodiment of the invention, first portion has a length of about 50 mm. In an embodiment of the invention, first portion has a length of at least, or above about 30 mm. In an embodiment of the invention, first portion has a length of at least, or above about 35 mm, or at least, or above about 40, or at least, or above about 45 mm, or at least, or above about 50 mm. In one or more embodiment, first portion of the herein disclosed connectors includes a first slope which declines towards first connector end. First slope allows the coupling of the first portion and engagement thereof with a first irrigation device.

In one or more embodiment, second portion of the herein disclosed connectors includes a second slope which declines towards second connector end. Second slope allows the coupling of the second portion and engagement thereof with a second irrigation device.

The enabled engagement or coupling is thus safe preventing possible damages for the inner portion of the irrigation device(s). In one or more embodiments, the safe engagement means that no damage is caused to the irrigation device with which the herein disclosed connector is engaged with. For example, in cases where the irrigation device(s) include(s) seals (such as an O-ring) at the internal surface thereof, the slope prevents possible damages, such as dislocations and ruptures to the seals.

In one or more embodiments, the declined first and/or second slopes define(s) an angle of less than about 85° between the slope and a horizontal axis of the connector. For example, the angle is less than about 80°. For example, the angle is between about 20° and about 80°, between about 30° and about 70°, between about 30° and about 50°, or between about 40° and about 60°.

In one or more embodiments, the slope has a length of about 3 mm to about 10. For example, about 4 mm to about 8 mm, or about 5 mm to about 7 mm.
