SYSTEM AND METHOD FOR A FRAME ASSEMBLY

摘要

A kit and method for assembling a frame supporting a stretched sheet includes a set of four stretcher bars, a set of braces, a stretching lever, and a sheet of material. A first stretcher bar can be initially attached to a first edge of the sheet. Remaining second, third, and fourth stretcher bars can be assembled with the first stretcher bar and corner braces to form a frame that rests upon the sheet. The stretching lever can be used to stretch the sheet between opposing stretcher bars just before the sheet is attached to a stretcher bar. The method of using a stretching lever as opposed to stretching pliers greatly reduces the time and difficulty of uniformly stretching the sheet.

主权项

1. A kit for assembling a frame with a stretched sheet comprising:
a sheet having an edge; a set of four stretcher bars including first, second, third, and fourth stretcher bars to be assembled end to end to form a frame whereby the first and third stretcher bars define opposite sides of the frame, each stretcher bar having a lower surface to be disposed upon the sheet during assembly and an opposing upper surface, the third stretcher bar defining a vertical surface that faces the first stretcher bar; a first stretching lever having opposing upper and lower edges, the lower edge to be placed against the vertical surface and the upper edge to be attached to the edge of the sheet whereby rotation of the upper edge toward the first stretcher bar tensions the sheet along a direction perpendicular to a major axis of the third stretcher bar.
