DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE ART
This invention relates to sheet stretchers for stretching a sheet or a construction used on the site of constructing, taking down, or repairing a building or the like or at the painting site, or a sheet for the prevention of paint scattering, or a sheet for advertisement displays used in outdoor advertisements, and also relates to sheets to be stretched by such sheet stretchers and attachment adjusters for attaching such sheet stretchers to a frame of the scaffolding.
Besides, this invention relates to sheet assemblies which are used on a construction site, or on a painting site, of constructing, taking down, or repairing a building, or at an outdoor advertisement as well as sheet removal preventers used in the sheet assemblies.
BACKGROUND ART
For example, on a construction site, a scaffolding is set up around a building and a sheet is stretched around the scaffolding. Conventionally, in such sheet stretching, unit sheets or a sheet and a scaffolding are connected by rope or wire being passed sequentially through eyelets provided in the respective sheets.
The workability of stretching sheets with the rope passed through the eyelets as described above is extremely low, and much time is spent. The connection by the rope is not so satisfactory because unit sheets with eyelets must be prepared and unit sheets themselves cannot help being expensive. These problems arise similarly in sheets which are put up at a painting site or sheets for advertisement display used at tile outdoor advertisement and the like.
In view of the above, it is an object of the present invention to provide an sheet stretcher which is capable of stretching a sheet very easily, a sheet to be stretched by the stretcher as well as an attachment adjuster which is capable of adjusting the position of connection of the sheet stretcher to a scaffolding or the like.
DISCLOSURE OF THE INVENTION
According to the present invention, the above object is achieved by a sheet stretcher having a first hole for slidably receiving an expanded portion formed at an edge of a sheet and a first slit continuous to tile first hole and through which the edge of the sheet continuous to the expanded portion is insertable.
Furthermore, according to the present invention, the above object is achieved by a sheet stretcher having a second hole formed opposite to the first slit for slidably receiving an expanded portion of an attachment adjuster having an attachment plate continuous to the expanded portion or a further expanded portion formed at an edge of a further sheet; and a second slit formed continuous to the second hole and formed opposite to the first slit and through which the attachment plate of the attachment adjuster or the edge of the further sheet formed continuous to the further expanded portion is insertable.
According to the present invention, the above object is achieved by an attachment adjuster for attaching to a frame a sheet stretcher having a first hole for slidably receiving an expanded portion formed at an edge of a sheet; a first slit continuous to the first hole and through which the edge of the sheet formed continuous to the expanded portion is insertable; a second hole formed opposite to the first hole; a second slit continuous to the second hole and-formed opposite to the first slit, the adjuster comprising an expanded portion to be received slidably in the second hole and an attachment plate continuous to the expanded portion and extendible through the second slit.
According to the present invention, the above object is also achieved by 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
