Abstract
A quick change PVC pipe connection system (10) comprises a pipe (12) having a pair of opposite spaced apertures (14) extending through one end (16). A fitting (18) has a flange (20) with a pair of opposite spaced orifices (22) extending through the flange (20). A pair of pins (24) are provided. A facility (26) within the pipe (12) is for forcing each pin (24) through one aperture (14) in the pipe (12) and into one orifice (22) in the flange (20) of the fitting (18), when the end (16) of the pipe (12) is inserted into the flange (20) of the fitting (18), so as to retain the pipe (12) to the fitting (18).
Claims17
A quick change PVC pipe connection system comprising:
- a) a pipe having a pair of opposite spaced apertures extending through one end;
- b) a fitting having a flange with a pair of opposite spaced orifices extending through said flange;
- c) a pair of pins;
- d) a torsion wire spring within said pipe for forcing each said pin through one said aperture in said pipe and into one said orifice in said flange of said fitting, when said end of said pipe is inserted into said flange of said fitting, so as to retain said pipe to said fitting;
- and
- e) means for sealing the connection between said pipe and said fitting, so that a fluid can pass between said pipe and said fitting without a leakage therefrom.
A quick change PVC pipe connection system comprising:
- a) a pipe having a pair of opposite spaced apertures extending through one end;
- b) a fitting having a flange with a pair of opposite spaced orifices extending through said flange;
- c) a pair of pins:
- d) a torsion wire spring within said pipe for forcing each said pin through one said aperture in said pipe and into one said orifice in said flange of said fitting, when said end of said pipe is inserted into said flange of said fitting, so as to retain said pipe to said fitting, said torsion wire spring having:
- i) a coiled portion
- ii) a pair of arms, in which each said arm extends from one side of said coiled portion;
- and
- iii) means for connecting a distal free end of each said arm to one said pin;
- and
- e) means for releasing both of said pins from said orifices in said flange of said fitting, so that said end of said pipe can be removed from said flange of said fitting, wherein said releasing means includes:
- i) each of said pins having a top hole therein;
- and
- ii) a disassembly tool being a generally V-shaped heavy duty flexible wire having right angle bent ends, whereby when said tool is squeezed said bent ends can engage with said top holes in said pins to push said pins out of said orifices in said flange of said fitting.
A quick change PVC pipe connection system comprising:
- a) a pipe having a pair of opposite spaced apertures extending through one end;
- b) a fitting having a flange with a pair of opposite spaced orifices extending through said flange;
- c) a pair of pins;
- d) a torsion wire spring within said pipe for forcing each said pin through one said aperture in said pipe and into one said orifice in said flange of said fitting, when said end of said pipe is inserted into said flange of said fitting, so as to retain said pipe to said fitting, said torsion wire spring having:
- i) a coiled portion
- ii) a pair of arms, in which each said arm extends from one side of said coiled portion;
- and
- iii) means for connecting a distal free end of each said arm to one said pin, each said connecting means including:
- a rivet extending from a bottom end of said pin;
- and a loop formed on said distal free end of said arm, whereby said loop extends about said rivet to hold said pin thereto;
- and
- e) means for releasing both of said pins from said orifices in said flange of said fitting, so that said end of said pipe can be removed from said flange of said fitting, wherein said releasing means includes:
- i) each of said pins having a top hole therein;
- and
- ii) a disassembly tool being a generally V-shaped heavy duty flexible wire having right angle bent ends, whereby when said tool is squeezed said bent ends can engage with said top holes in said pins to push said pins out of said orifices in said flange of said fitting.
