Pipe joint unit

A pipe joint unit for interconnection with a pair of pipes comprising:

• a body member having an opening with a longitudinal axis extending from one end to the other end of the body member, the opening being of a size to slidingly extend over an end and an outer diameter of the pipes, the body member including a pair of approximately rectangular apertures on either side of the body member extending into the opening and aligned to provide axes between matching apertures that are nonparallel with the longitudinal axis of the opening;
• sealing means positioned within the opening and between the respective axes of the apertures and of a configuration to sealingly contact the end of the pipes;
• and
• a pair of elongated key members configured to lit within the respective apertures and extend through the body member and a portion of the opening, wherein the key members have a substantially rectangular configuration compatible in size with the approximately rectangular apertures with a raised securing rib extending diagonally along their length, the location of the apertures and the size of the key members cause the respective key members to deform any pipes of approximately the size of an inner diameter of the opening mounted within the body member, while the diagonal arrangement of the raised securing rib forces the pipes in a progressively tighter sealing contact with the sealing means, wherein the key members will secure the pipe joint unit to the pipes, and the sealing member will seal the pipes.

A pipe joint unit for interconnection with a pair of pipes comprising:

• a body member having an opening with a longitudinal axis extending from one end to the other end of the body member, the opening being of a size to slidingly extend over an end and an outer circumference of the respective pipes, the body member including a pair of approximately rectangular apertures on either side of the body member extending interiorly through a portion of the body member and into the opening and aligned to provide axes between matching apertures that are nonparallel with the longitudinal axis of the opening;
• first sealing means positioned within the opening and between the respective axes of the apertures and of a configuration to sealingly contact the respective ends of the pipes when they are abutted against the first sealing means;
• second sealing means positioned within the body member and extending about respective outer circumferences of the pipes to sealingly contact the respective outer circumferences of the pipes when they are abutted against the first sealing means;
• and
• a pair of elongated key members configured to fit within the respective apertures and to extend through the body member and a portion of the opening wherein the key members are independent of each other and have a substantially rectangular cross-section configuration compatible in size with the approximately rectangular apertures of the body member with a raised securing rib projecting from the rectangular cross-section and extending along a length of each key member, the securing rib has a tapered portion adjacent one end of the respective key members, each key member has an enlarged striking surface at the other end, which is axially aligned with the securing rib, the location of the apertures and the size of the key members cause the respective securing ribs to deform any pipes of approximately the size of an inner diameter of the opening mounted within the body member, the securing rib is forced against the pipe by the corresponding rectangular aperture when a force is exerted against the striking surface on the key member to secure the pipe joint unit to the pipes, while the first and second sealing means will seal the connected pipes.

• core means positioned within the opening and between the respective axes of the apertures and of a configuration to contact and support the respective ends of the pipes when they are abutted against the core means;
• first sealing means positioned within the body member and extending about respective outer circumferences of the pipes to sealingly contact the respective outer circumferences of the pipes when they are abutted against the core means;
• and
• a pair of elongated key members configured to fit within the respective apertures and to extend through the body member and a portion of the opening wherein the key members are independent of each other and have a substantially rectangular cross-section configuration compatible in size with the approximately rectangular apertures of the body member with a raised securing rib projecting from the rectangular cross-section and extending along a length of each key member, the securing rib has a tapered portion adjacent one end of the respective key members, each key member has an enlarged striking surface at the other end, which is axially aligned with the securing rib, the location of the apertures and the size of the key members cause the respective securing ribs to deform any pipes of approximately the size of an inner diameter of the opening mounted within the body member, the securing rib is forced against the pipe by the corresponding rectangular aperture when a force is exerted against the striking surface on the key member to secure the pipe joint unit to the pipes, while the first sealing means will seal the connected pipes.

A pipe joint unit for interconnection with a pair of pipes, each having a tapered portion at a respective end, comprising:

• a body member having an opening with a longitudinal axis extending from one end to the other end of the body member, the opening being of a size to slidingly extend over an end and an outer circumference of the respective pipes, the body member including a pair of approximately rectangular apertures on either side of the body member extending interiorly through a portion of the body member and into the opening and aligned to provide axes between matching apertures that are nonparallel with the longitudinal axis of the opening;
• sealing means positioned within the opening and between the respective axes of the apertures and of a configuration to sealingly contact the respective tapered ends of the pipes when they are abutted against the sealing means;
• and
• a pair of elongated key members configured to fit within the respective apertures and to extend through the body member and a portion of the opening wherein the key members are independent of each other and have a substantially rectangular cross-section configuration compatible in size with the approximately rectangular apertures of the body member with a raised securing rib projecting from the rectangular cross-section and extending diagonally along a length of each key member, each key member has an enlarged striking surface at one end, the location of the apertures and the size of the key members cause the respective diagonal securing ribs to deform any pipes of approximately the size of an inner diameter of the opening mounted within the body member, the securing rib is forced against the pipe by the corresponding rectangular aperture when a force is exerted against the striking surface on the key member to secure the pipe joint unit to the pipes, while the diagonal arrangement of the raised securing ribs forces the pipes in a progressively tighter sealing contact with the sealing means, wherein the key members will secure the pipe joint unit to the pipes, and the sealing means will seal the pipes.
