Automated screen printing pallet and retaining frame assembly

A garment retaining frame adapted for use with a conventional screen printing pallet comprising, in combination;

• a) a supporting base including a forwardly extending pallet having a generally horizontal planar upper surface, a rear end, a forward end defining a loading position for receiving a layer of material in a generally planar condition and including a peripheral edge surrounding said planar upper surface;
• b) a retaining frame member having a central opening and conformed to receive the peripheral edge of said pallet in a close-fitting relationship to frictionally engage and secure a layer of material between said frame and the peripheral edge of said pallet;
• c) and mounting means movably connecting said frame to said supporting base between a raised open position free of engagement with said pallet and a closed position wherein side portions of said frame are disposed in said close-fitting relationship with the peripheral edge of said pallet;
• said mounting means including a first hinge rearwardly disposed relative to said pallet for rotating said frame about a generally horizontally disposed axis and a second hinge having a generally horizontal axis of rotation disposed adjacent to said forward end of said pallet and formed by the cooperative engagement of a forwardly disposed surface of said retaining frame and a portion of the forward end of said pallet during a selected portion of travel of said retaining frame between said open and closed positions;
• said first hinge being movably mounted along a selected path of travel between a first position permitting said retaining frame to rotate through a first selected arc and a second position vertically and horizontally spaced from said first position to permit said frame to be moved in a horizontal and vertical direction relative to said pallet and to be rotated about said second hinge axis through a second selected arc during travel between said open and closed positions.

A garment retaining frame adapted for use with a conventional screen printing pallet and screen printing apparatus comprising, in combination;

• a) a supporting base including a forwardly extending pallet having a generally horizontal planar upper surface, a forward end defining a loading position for receiving a layer of material in a generally planar condition and a peripheral edge surrounding said upper surface;
• b) a retaining frame having a central opening and conformed to receive the peripheral edge of said pallet in a close-fitting relationship to frictionally engage and secure a layer of material between said frame and the peripheral edge of said pallet;
• said retaining frame movably mounted to said supporting base about a first hinge for rotation about a generally horizontal axis and a second hinge for rotation about a horizontal axis spaced vertically and horizontally from said first hinge to define first and second different arcs of travel of said retaining frame between an open position with said retaining frame raised above and non-engaging said pallet and a closed position with vertically disposed side portions of said retaining frame disposed in said close-fitting relationship with the peripheral edge of said pallet;
• an arm having a forward end fixed to said frame and an opposing end extending rearwardly of said pallet, said opposing end movably mounted to said supporting base between a raised position defining said first hinge and a lowered position horizontally displaced relative to said raised position.

The combination of a screen printing pallet and retaining frame comprising:

• a) a supporting base;
• b) a pallet fixed to said base including a outwardly extending, horizontally disposed planar surface for receiving a flexible material for printing and having a peripheral edge surrounding said planar surface;
• c) a retaining frame having a central opening and an inner surface conformed to receive the peripheral edge of said pallet in close-fitting relationship to frictionally engage a layer of material disposed between said inner surface of said retaining frame and said peripheral edge of said pallet, a rearward end of said retaining frame being movably mounted to said base for travel between a raised and lowered position including being pivoted about a first horizontal hinge axis in said raised position and horizontally displaced in said lowered position relative to its raised position, a forward edge of said frame being selectively pivotable about a second horizontal hinge axis formed at or near a forwardly disposed edge of said pallet by a cooperative engagement between said forward edge of said frame and said pallet during a selected portion of a path of travel of said frame between a fully open position defined when said retaining frame is raised in non-engaging relationship above said pallet and a fully closed position defined when said inner surface of said retaining frame is disposed in said close-fitting relationship with the peripheral edge of said pallet;
• and
• d) means for applying a force operable on said retaining frame at a point located between said first and second hinge axes to cause said retaining frame to move between said open and closed positions.
