Abstract
A sheet stretcher (7) comprises a base (7a), which has a hole (17) for slidably receiving an expanded portion (5) formed at an edge of a sheet (2), a slit (18) communicating with the hole (17) and through which the end portion (11) of the sheet (2) continuous to its expanded portion (5) is insertable, a hole (19) for slidably receiving a further expanded portion (5) formed at an edge of a further sheet (2), a slit (20) communicating with the hole (19) through which the end portion (11) of the further sheet (2) continuous to the further expanded portion (5) is insertable.
Claims8
An attachment adjuster for attaching a sheet stretcher to a frame, the stretcher comprising a base and connecting means formed at the base to connect the base with a frame for stretching a sheet, the base including a first hole for slidably receiving an expanded portion formed at an edge of the sheet;
- a first slit communicating with the first hole and through which the edge of the sheet formed continuous to the expanded portion is insertable;
- a second hole for slidably receiving a further expanded portion formed at an edge of a further sheet;
- a second slit communicating with the second hole and through which the edge of the further sheet continuous to the further expanded portion is insertable;
- a third hole;
- and a third slit communicating with the third hole;
- the attachment adjuster having an expanded portion to be slidably received in the third hole and a plate portion integral with the expanded portion so as to be extendible through the third slit.
A sheet stretcher comprising a base having at one end thereof a first hole for slidably receiving an expanded portion formed at an edge of a sheet, and a first slit in communication with the first hole and through which the edge of the sheet continuous to the expanded portion is insertable;
- and having at another end thereof a second hole for slidably receiving a further expanded portion formed at an edge of a further sheet, and a second slit in communication with the second hole and through which the edge of the further sheet continuous to the further expanded portion is insertable, the base having a substantial rectangular shape in cross-section thereof and having a slot into which a string-like member for connecting the sheet stretcher with a frame is insertable, the slot being disposed at a central portion of the base between the first and second holes, and passing through the base.
A sheet stretcher comprising a base and connecting means formed at the base to connect the base with a frame for stretching a sheet, the base having a first hole for slidably receiving an expanded portion formed at the edge of the sheet;
- a first slit communicating with the first hole and through which the edge of the sheet formed continuous to the expanded portion is insertable;
- a second hole for slidably receiving a further expanded portion formed at an edge of a further sheet;
- and a second slit communicating with the second hole and through which the edge of the further sheet continuous to the further expanded portion is insertable, the connecting means having a third hole formed in the base;
- and a third slit formed in the base so as to communicate with the third hole and said stretcher further comprising an attachment adjuster having an expanded portion to be slidably received in the third hole;
- and a plate portion integral with the expanded portion and insertable through the third slit.
A sheet stretcher comprising a base having at one end thereof a first hole for slidably receiving an expanded portion formed at an edge of a sheet, and a first slit in communication with the first hole and through which the edge of the sheet continuous to the expanded portion is insertable;
- and having at another end thereof a second hole for slidably receiving a further expanded portion formed at an edge of a further sheet, and a second slit in communication with the second hole and through which the edge of the further sheet continuous to the further expanded portion is insertable, the base having a slot into which a string-like member for connecting the sheet stretcher with a frame is insertable, the slot being disposed between the first and second holes, and passing through the base.
