Abstract
The present invention relates to means and methods for tensioning duck or canvas. In particular, the present invention provides a tensioning system wherein a canvas can be tensioned dynamically along one or two sides of a frame. The present invention also further provides a method for dynamic tensioning of a canvas on one or two sides of a frame.
Claims21
A single-sided tensioning system for the dynamic tensioning of at least one canvas provided on one side of a frame, which is assembled substantially from four or more frame profiles, the tensioning system comprising:
- a frame profile comprising a back wall with an upright central part and two upright side walls, which extend in the lateral direction of the frame;
- wherein the frame profile is provided with at least one stop;
- a guide provided with a fastener configured to fasten a canvas;
- wherein the guide is mounted movably in the lateral direction in the frame profile between the central part and a side wall of the two upright side walls;
- a locking element comprising a coupler and a blocking piece;
- wherein the coupler is configured to couple the locking element to the central part;
- a tensioner configured for dynamic tensioning of the canvas fastened to the guide;
- wherein the tensioner is configured in at least one of the following configurations:
- the tensioner is tensioned between the stop and guide to tension the guide dynamically in the central direction of the frame, the blocking piece configured to block a movement of the guide in at least one direction, and
- the tensioner is tensioned between the blocking piece and guide to tension the guide dynamically in the central direction of the frame, the stop configured to block a movement of the guide in at least one direction;
- wherein at least one of the locking element and the blocking piece is configured to remove said blocking of the guide displacement relative to the frame profile so that the canvas fastened to the guide is tensioned dynamically over the side wall of the frame profile by the tensioner.
A double-sided tensioning system for the dynamic tensioning of at least two canvases provided on either side of a frame, which is assembled substantially from four or more frame profiles, the tensioning system comprising:
- a frame profile comprising a back wall with an upright central part and two upright side walls, which extend in the lateral direction of the frame;
- wherein the frame profile is provided with at least one stop on either side;
- at least two guides, each provided with a fastener configured to fasten a different canvas;
- wherein each guide is mounted movably in the lateral direction in the frame profile-between the central part and a different side wall of the two upright side walls;
- a locking element comprising a coupler and at least two blocking pieces provided on either side of the locking element;
- wherein the coupler is configured to couple the locking element to the central part;
- at least two tensioners configured for dynamic tensioning of the canvases fastened to the at least two guides;
- wherein each of the at least two tensioners is configured in at least one of the following configurations:
- the tensioner is tensioned between a respective stop and guide to tension the guide dynamically in the central direction of the frame, each of the at least two blocking pieces configured to block a movement of a respective guide in at least one direction, and
- the tensioner is tensioned between a respective blocking piece and guide to tension the guide dynamically in the central direction of the frame, each of the stops configured to block a movement of a respective guide in at least one direction;
- wherein at least one of the locking element and the blocking pieces is configured to remove said blocking of the guides by displacement relative to the frame profile so that the canvases fastened to the at least two guides are tensioned dynamically over the different side walls of the frame profile.
