1. Field of Invention
This invention relates to opening and closing of doors, windows, gates, signs, or objects that would require a hinge movement.
2. Prior Art
All doors, windows, and gates, most use hinges. Door hinges are usually concealed butt hinges, that only allow the door to swing as it also protrudes, making the access area smaller, by the thickness of the door. Surface mounted hinges, that can be offset allow more walk through area. Also wheel chair clearance.
You hardly see butt hinges or making them attractive is out. Surface mounted hinges that are eye catching, add beauty, plus sales appeal.
Objects and Advantages
A hinge is required in the operation of all doors, gates, some windows, and some signs that open, shut, or have some movement. They are easier to install, adding much mor beauty. The function is to open wider by offsetting the hinges.
The body of the hinge can be made from flat sheet steel. By cutting or stamping a punch press is normally used in production. The pin housing is also formed with use of a punch press—a machine built for this purpose. For smaller applications, you can machine cut this outline of the bodies. The pin section housing may be manually cut and then welded to the hinge body to form the pin body. The pin is made from round stock to fit the pin body.
There is almost no end to designs off these surface mounted hinges. All shown (page 3) of the front view by turning them over will reverse the image. Offset hinge exhibit A (page 3) may also be reversed for doors that swing either way.
Hinges of steel construction usually cut or stamped, can also be torch cut, and machine formed, or punch press formed to hold a pin that two outer sections pivot on—giving it the hinge effect. The offset hinge may be made with one body being wider than the other so that it may be offset and still have the ability to be fastened to background material that will hold the screws. So sometimes #13 and #14 body parts will be wider.
Operation of Invention
Being a hinge only has one moving part as one half is normally secured.
Hinges that bend or swing in the middle are hinges, but decorative hinges have sales appeal. Surface mounted hinges are applicable, as they may be offset, another invention.
Surface mounted hinges are much easier to install, does not require the education of a carpenter, or the working skill of countersinking, measuring, and chiseling.
