Abstract
A frame jamb marker includes a sliding panel for sliding on the side surface of the frame and a guiding panel perpendicularly extended from the sliding panel for sliding on the marking surface of the frame, wherein the guiding panel has a top stepping edge and a bottom stepping edge to define a top marking point and a bottom marking point at stepping corners at the top and bottom stepping edges respectively. The user is able to point a marker tool on the marking surface at one of the top and bottom marking points. When the sliding panel is slid on the side surface to drive the guiding panel sliding on the marking surface, the marker tool is guided to slidably mark on the marking surface to make a straight marking line thereon so as to precisely form the marking line parallel to the common edge of the frame.
Claims10
A frame jamb marker for a frame having a side surface perpendicularly extended from a marking surface along a common edge, wherein the frame jamb mark comprises:
- a sliding panel adapted for being slid on said side surface of said frame;
- and
- a guiding panel perpendicularly extended from said sliding panel along a common guiding edge for being driven to slide on said marking surface when said sliding panel is slid on said side surface, wherein said guiding panel has a top stepping edge at a topmost edge of said guiding panel, and a bottom stepping edge at a bottommost edge of said guiding panel defining at least a top marking point and at least a bottom marking point at stepping corners at said top and bottom stepping edges respectively, wherein said guiding panel comprises a first guiding portion and a second guiding portion having a length shorter than a length of said first guiding portion, wherein said top stepping edge has a first step portion defined at a top edge of said first guiding portion and a second step portion defined at a top edge of said second guiding portion, wherein said bottom stepping edge has a first step portion defined at a bottom edge of said first guiding portion and a second step portion defined at a bottom edge of said second guiding portion, wherein said second step portions of said top and bottom stepping edges are aligned with top and bottom edges of said sliding panel respectively,
- thereby, a user is able to point a marker tool on the marking surface at one of said top and bottom marking points, such that when said sliding panel is slid on said side surface of said frame to drive said guiding panel to slid on said marking surface, said marker tool is guided to slidably mark on said marking surface to make a straight marking line thereon so as to precisely form said marking line parallel to said common edge of said frame.
A frame jamb marker for a frame having a side surface perpendicularly extended from a marking surface along a common edge, wherein the frame jamb mark comprises:
- a sliding panel adapted for being slid on said side surface of said frame;
- and
- a guiding panel perpendicularly extended from said sliding panel along a common guiding edge for being driven to slide on said marking surface when said sliding panel is slid on said side surface, wherein said guiding panel has a top stepping edge at a topmost edge of said guiding panel, and a bottom stepping edge at a bottommost edge of said guiding panel defining a plurality of top marking points and a plurality of bottom marking points at stepping corners at said top and bottom stepping edges respectively, wherein said guiding panel has a plurality of guiding portions defining a plurality of portions of said top and bottom stepping edges, wherein each portion of said top and bottom stepping edges has a L-shaped configuration that said top and bottom marking points are formed at corners of said portions of said top and bottom stepping edges respectively, wherein each of said top stepping edges further has a plurality of step portions extended horizontally and parallel to a top edge of said sliding panel while said bottom stepping edges also has a plurality of step portions extended horizontally and parallel to a bottom edge of said sliding panel, wherein horizontal levels of said step portions of said top stepping edge is gradually elevating from said common guiding edge of said guiding panel to an outer edge thereof while horizontal levels of said step portions of said bottom stepping edge is gradually descending from said common guiding edge of said guiding panel to said outer edge thereof,
- thereby, a user is able to point a marker tool on the marking surface at one of said top and bottom marking points, such that when said sliding panel is slid on said side surface of said frame to drive said guiding panel to slid on said marking surface, said marker tool is guided to slidably mark on said marking surface to make a straight marking line thereon so as to precisely form said marking line parallel to said common edge of said frame.
