This invention relates to the tensioning of sheet material such as PVC, canvas and other textiles for forming banners, signage, vehicle graphics and the like.
Many methods of tensioning sheet material have been proposed, some of which have employed rivets for attachment to a frame, while another has utilised rods in a peripheral hem of the sheet material for insertion into a complemental channel in the frame.
It is an object of the present invention to provide a very simple arrangement which is easy to use and which results in a firm anchor as well as an excellent aesthetic appearance.
According to the invention an assembly for the tensioning of sheet material in a frame includes a channel in the frame adapted to receive the sheet material and a flexible strip having formations which are a force-fit into the channel to hold the sheet material therein and which, on release expand against the sheet material for a positive anchorage.
In a preferred form of the invention the channel has an opening which is narrower than the channel and the strip has feet which engage under the opening when released from the step of force-fitting into the channel.
The strip may be made from a suitable polymeric material and which includes a portion insertable into the channel of the frame and a top portion which has a surface which is aesthetically chosen for the particular article involved.
An embodiment of the invention is described below with reference to the accompanying drawings, in which:
The strip 20—see
The sheet material is located over the frame and the strip is force-fitted into the channel to capture the sheet material 21 between the zone 22 and the channel. It may be necessary to use a mallet to effect the force-fit of the zone 22 into the channel. Once into the channel the zone 22 relaxes and engages the sheet material in the channel below the edges of the narrow opening thereof—see
The top surface 30 of the strip may be plain or patterned to suit the requirements. In
