Abstract: A screen extending frame including cut grooves formed from an inner side to an outer side thereof, or from the outer side to the inner side, or in both directions of joints of the screen extending frame, which is constituted by connecting four frame members in a rectangle shape. The cut grooves enable the joints to deform. The four frame members are individual bodies that are joined by comer members, and connecting portions are inclined with respect to the longitudinal direction of the frame members. Gaps are created in the connections. Elastic elements can be placed at the connections of the four frame members. Alternatively, the joint portions are orthogonal to the longitudinal direction, and elastic elements are placed at the joints.

The cut grooves enable the joints to deform. The four frame members are individual bodies that are joined by corner members, and connecting portions are inclined with respect to the longitudinal direction of the frame members. Gaps are created in the connections. Elastic elements can be placed at the connections of the four frame members. Alternatively, the joint portions are orthogonal to the longitudinal direction, and elastic elements are placed at the joints.

Abstract: A screen extending frame in which a screen attached thereto is not distorted even when a screen extending jig is removed therefrom for storage or transportation is provided. Cut grooves are formed from the inner side to the outer side of, or from the outer side to the inner side of the direction, or in both directions of couplings of the screen extending frame constituted by connecting four frame members in a rectangle shape by means of welding, or the like, and the cut grooves enable the couplings to deform. The four frame members constituting the screen extending frame, which are individual bodies, join by corner members, and connecting portions are inclined with respect to the longitudinal direction of the frame members, thereby gaps are created in the connections. Alternatively, elastic elements are placed at the connections of the four frame members constituting the screen extending frame.

Abstract: An extension tool is provided for stretching a sheet-shaped material over its entirety with minimal adjusting portions and uniform tension. Four corner members are disposed along with four frame members for forming a rectangular frame. Four rods are disposed so as to pass through the four frame members and allow the sides and corners to move towards and away from each other for adjusting the size of the frame. One set of corner members are located on the diagonals and are provided with a moving mechanism for moving the rods along the sides of the rectangle. The extension tool for tensioning the material further comprises a transmission mechanism for converting the movement of a rod in a first side of the rectangle between first corner pairs into a reversing and approaching movement of a second rod in a second side of the frame between second corner pairs.

Abstract: The present invention relates to a screen for screen printing. More particularly, structure of the screen can have different types of mesh or sheets joined together. The present invention also relates to a method of detachably spreading a screen to a screen frame.

Abstract: An extension tool of a sheet-shaped material comprising, in order to stretch a sheet-shaped material over its entirety at minimum adjusting portions and with a uniform tension, four corner members disposed at locations corresponding to the four corners of a rectangle, four frames disposed at locations corresponding to the sides of the rectangle and supported at the opposite ends thereof by the corner members so as to be movable in the directions of the sides, and four rods disposed so as to pass through the four frames respectively. One set of corner members located on the diagonals of the rectangle are respectively provided with moving mechanism for moving the rods along the sides of the rectangle.
