-
FIG. 1 is a top view of a canvas stretcher according to an embodiment of the invention in an assembled configuration. -
FIG. 2 is a top view of the canvas stretcher in a partially dissembled configuration. -
FIG. 3 is a bottom view of the canvas stretcher. -
FIG. 4 is a side view of the canvas stretcher. - The invention is a canvas stretcher, as illustrated at 10 in the figures. The
canvas stretcher 10 generally includes afirst gripping mechanism 20, asecond gripping mechanism 22 and atension mechanism 24 that interconnects thefirst gripping mechanism 20 and thesecond gripping mechanism 22. - A unique feature of the
canvas stretcher 10 is that thefirst gripping mechanism 20 and thesecond gripping mechanism 22 are linked and pulled together so that a force on one of the gripping mechanisms also causes a force on the other gripping mechanism. This configuration enables the canvas stretched 10 of the present invention to be free-standing and reduces the number of force-generating stretching components used in prior art devices from two to one in the present invention. - To assist in evenly stretching canvas or other material using the
canvas stretcher 10, thefirst gripping mechanism 20 and thesecond gripping mechanism 22 may be selected with a length that is approximately the same as the length of the canvas or other material that is being stretched. Alternatively, it is possible for thecanvas stretcher 10 to be formed with a length that is less than the length of the canvas or other material that is being stretched and to use two ormore canvas stretchers 10 adjacent to each other. - The
first gripping mechanism 20 and thesecond gripping mechanism 22 may have a substantially similar configuration that generally includes alower plate 30 and anupper plate 32. Thelower plate 30 and theupper plate 32 may have an approximately equal length and may be substantially flat. - The
lower plate 30 and theupper plate 32 may be interconnected with at least oneattachment mechanism 40. To facilitate obtaining an approximately equal gripping ability along the length of thefirst gripping mechanism 20 and thesecond gripping mechanism 22, there may be a plurality ofattachment mechanisms 40 that are oriented in a spaced-apart configuration along thelower plate 30. - In one configuration, the
attachment mechanism 40 includes aknob 42 that is attached to a threaded stud (not shown) that extends from thelower plate 30. To enhance the ability to grip theknob 42, theknob 42 may include a textured surface such as at least oneextension 44 extending therefrom. - To facilitate gripping the
upper plate 32 with theattachment mechanism 40, theupper plate 32 may include at least oneslot 46 or aperture formed therein. The at least oneslot 46 is oriented on theupper plate 32 to generally correspond with the position of theattachment mechanisms 40 on thelower plate 30. - Using the at least one
slot 46 enables theattachment mechanisms 40 to be positioned in a partially engaged position prior to positioning the canvas or other material being stretched and then theupper plate 32 is slid into position over thelower plate 30 by moving theattachment mechanisms 40 to extend into theslots 46. This technique minimizes disturbance of the canvas or other material being stretched to thereby facilitate substantially even stretching of the canvas or other material. - The
tension mechanism 24 is adjustable to enable thecanvas stretcher 10 to be used in conjunction with canvas or other material having a variety of widths. Thetension mechanism 24 may include alock mechanism 50, anattachment plate 52 and abelt 54. - The
lock mechanism 50 may be attached to thelower plate 30 of thefirst gripping mechanism 20. Thelock mechanism 50 allows thebelt 54 to be positioned therein. Thelock mechanism 50 may be positionable in a locking configuration and a release configuration. When in the locking configuration, thelock mechanism 50 allows thebelt 54 to be tightened such as when stretching the canvas or other material. When in the release configuration, thelock mechanism 50 allows thebelt 54 to be loosened such as when done using thecanvas stretcher 10. Thelock mechanism 50 may operate using a ratcheting type system. - In an alternate configuration, the
canvas stretcher 10 includes at least twotension mechanisms 24 that are mounted at selected locations along thefirst gripping mechanism 20 and thesecond gripping mechanism 22. Using at least twotension mechanisms 24 enhances the ability to evenly stretch the canvas or other material when the canvas or other material has a relatively large width. - The
lock mechanism 50 may include ashaft 56, alocking arm 58 and ahandle 60. Thehandle 60 is operably attached to thelocking arm 58 to move thelocking arm 58 between the locking configuration and the release configuration. Thelocking arm 58 may be biased to the locking configuration. - The
attachment plate 52 may be attached to thelower plate 30 of thesecond gripping mechanism 22. Theattachment plate 52 may have anaperture 62 formed therein that is adapted to receive ahook 64 that is attached to thebelt 54 to facilitate interconnecting thelock mechanism 50 and theattachment plate 52 with thebelt 54. - In operation, the
lower plate 30 of the firstgripping mechanism 20 is placed over a first portion of canvas or other material that is to be stretched. Theupper plate 32 of the firstgripping mechanism 20 is positioned adjacent thelower plate 30 of the firstgripping mechanism 20 so that theattachment mechanisms 40 at least partially extend into the associatedslots 46. Theknobs 42 are then tightened to retain the canvas or other material being stretched in a fixed position with respect to the firstgripping mechanism 20. - The process is then repeated to attach a second portion of canvas or other material that is to be stretched to the second
gripping mechanism 22. Thereafter, the canvas or other material that is to be stretched is placed over a frame (not shown) so that the first portion and the second portion extend over opposite sides of the frame. - The
hook 64 is extended into theaperture 62 to attach the firstgripping mechanism 20 to the secondgripping mechanism 22 using thebelt 54. With thelock mechanism 50 in the locking configuration, thebelt 54 is tightened to stretch the canvas or other material over the frame. The stretched canvas or other material is then used such as by painting a portrait thereon. When done using thecanvas stretcher 10, thelock mechanism 50 is moved to the release configuration and thebelt 54 is loosened. - The
hook 64 is detached from theattachment plate 52 and theknobs 42 are loosened to separate theupper plates 32 from thelower plates 30 and thereby detach the firstgripping mechanism 20 and the secondgripping mechanism 22 from the canvas or other material that was stretched. - It is contemplated that features disclosed in this application, as well as those described in the above applications incorporated by reference, can be mixed and matched to suit particular circumstances. Various other modifications and changes will be apparent to those of ordinary skill.
