Patent Application

The present invention generally relates to hinges for connection of two solid objects for movement about a fixed axis with respect to each other, and more particularly to a foldable hinge assembly having an integral living hinge for assembly to the door in a flat configuration.
While it is unclear as to when hinges were invented, numerous types of hinges are currently known in the art. In ancient times hinges were used to make massive objects, such as protective gates, moveable. These hinges were typically not available to the average homeowner, but they still provided them with the benefit of protection if their home was positioned behind the heavy hinged gate.
Through the centuries, hinges have been constructed from various types of metals including brass, bronze, iron and steel. They have also been constructed in various specialized configurations.
Currently, hinges provide us with security for our homes, convenience within our homes, and strength to move objects we normally could not move. Hinges are included in our doors, windows, cabinets, appliances and the like, which add convenience to our everyday lives.
While hinges have become ubiquitous in our everyday lives, there remains a need for new hinges that offer new applications and ease of use features in order to achieve acceptance by the end user. These hinges should be easily and quickly assembled using minimal hardware and requiring a minimal number of tools. Further, the hinges should not require excessive strength to assemble or include numerous component parts requiring assembly. Moreover, the hinge must assemble together in such a way so as not to detract from the aesthetic appearance of the assembled hinge.
Thus, the present invention provides a foldable hinge assembly which overcomes the disadvantages of prior art hinges. The foldable hinge assembly of the present invention not only provides for relative ease of assembly and few component parts, it also permits assembly without the need to remove a door from its frame.
Briefly, the invention involves a hinge construction. The hinge construction includes a pair of contoured wing members connected at one end with a living hinge, each wing member including a portion of a hinge barrel. The wings are constructed to be folded around a hinge pin so that the hinge barrel is formed while positioning the wings in a generally parallel relationship with respect to each other. A portion of a wall or door jamb can then be positioned between or adjacent to the wings. Fasteners can then be secured through the wings to fix the assembly, whereby the hinge pin is free to rotate within the barrel created by the folded wings.
Accordingly, it is an objective of the present invention to provide a foldable hinge assembly.
It is a further objective of the present invention to provide a foldable hinge assembly which forms a hinge barrel upon folding.
It is yet a further objective of the present invention to provide a foldable hinge assembly having a living hinge connecting the wing members of the hinge.
It is another objective of the present invention to provide a foldable hinge assembly including alignment bosses for aligning the wing members.
It is another objective of the present invention to provide a foldable hinge assembly that includes a plurality of internal radially extending ribs.
Other objectives and advantages of this invention will become apparent from the following description taken in conjunction with the accompanying drawings wherein are set forth, by way of illustration and example, certain embodiments of this invention. The drawings constitute a part of this specification and include exemplary embodiments of the present invention and illustrate various objects and features thereof.

Any drawings contained herein constitute a part of this specification and include exemplary embodiments of the present invention and illustrate various objects and features thereof.
While the present invention is susceptible of embodiment in various forms, there is shown in the drawings and will hereinafter be described a presently preferred embodiment with the understanding that the present disclosure is to be considered an exemplification of the invention and is not intended to limit the invention to the specific embodiments illustrated.
Referring generally to
Referring to
The hinge barrel 16 is sized and shaped to cooperate with a hinge pin 12 (
The U-shaped portion 28 generally includes an inner surface 40 which cooperates with the hinge pin 12 to maintain axial alignment between the two statically and dynamically. In at least one embodiment, the inner surface of the U-shaped portion of the first wing member includes a plurality of inwardly extending ribs 42. An innermost surface of the ribs 42 is sized to cooperate with an outer surface of the hinge pin. The ribs may be arranged in any manner that is suitable to the wear and load characteristics of the assembly. For example, the ribs may extend transversely, in axial alignment with the hinge pin, radially about the internal surface of the U-shaped portion, or any suitable combination. The ribs provide several advantages: they reduce weight and material requirements, and add strength to the wing member, while reducing friction to the assembly.
Still referring to
The second wing member 19 includes a second outwardly extending flange 46; the second flange is generally constructed and arranged to align with the first flange 30 when the foldable hinge assembly 100 is in the closed position (
