Abstract
A press can include an upper platen, a lower platen, a support arm, and an adjuster. The support arm can be adapted to move the upper platen substantially parallel to the lower platen between an open position and a closed position. The adjuster can have a cam adapted to engage a surface of the support arm and to rotate between a first rotational position and a second rotational position relative to the support arm. Rotation of the cam from the first rotational position to the second rotational position can move the upper platen toward the lower platen.
Claims23
A heat press for applying a heat transfer to a material, comprising:
- an upper platen;
- a lower platen;
- a support arm coupled to the upper platen and configured to move the upper platen between an open position and a closed position relative to the lower platen, said support arm including a first link fixedly-positioned relative to the lower platen, a second link rotatably coupled to the first link, a third link rotatably coupled to the second link, and a fourth link rotatably coupled to the third link and the first link;
- a first pressure adjustment mechanism configured to facilitate adjustment of an amount of pressure applied between the lower platen and the upper platen when in the closed position;
- and
- a second pressure adjustment mechanism configured to facilitate adjustment of an amount of pressure applied between the lower platen and the upper platen when in the closed position;
- wherein the second pressure adjustment mechanism includes a cam configured to rotate between a first rotational position and a second rotational position to increase a distance between the second link and the fourth link along the third link, thereby increasing an amount of pressure between the lower platen and the upper platen when in the closed position.
A heat press for applying a heat transfer to a material, comprising:
- an upper platen;
- a lower platen;
- a support arm coupled to the upper platen and configured to move the upper platen between an open position and a closed position relative to the lower platen;
- a first pressure adjustment mechanism configured to facilitate adjustment of an amount of pressure applied between the lower platen and the upper platen when in the closed position through a continuous range of possible pressures;
- and
- a second pressure adjustment mechanism configured to facilitate adjustment of an amount of pressure applied between the lower platen and the upper platen when in the closed position, wherein the second pressure adjustment mechanism includes a cam configured to rotate between a first rotational position and a second rotational position.

- a lower platen;
- a support arm coupled to the upper platen and configured to move the upper platen between an open position and a closed position relative to the lower platen, said support arm including a first link fixedly-positioned relative to the lower platen, a second link rotatably coupled to the first link, a third link rotatably coupled to the second link, and a fourth link rotatably coupled to the third link and the first link;
- a first pressure adjustment mechanism configured to facilitate adjustment of an amount of pressure applied between the lower platen and the upper platen when in the closed position;
- and
- a second pressure adjustment mechanism configured to facilitate adjustment of an amount of pressure applied between the lower platen and the upper platen when in the closed position;
- wherein:
- the second pressure adjustment mechanism includes a cam configured to rotate between a first rotational position and a second rotational position;
- the cam includes a cylindrical cam body extending along a cam body axis, the cam body being coupled to a pivot shaft;
- the cam body is rotatably received in a cylindrical aperture in the second link, the cam body and cylindrical aperture are coaxial;
- the pivot shaft is rotatably received through an aperture in the third link;
- and
- rotation of the cam body within the cylindrical aperture in the second link causes the pivot shaft to pivot about the cam body axis.
