ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to furniture hinges, and more particularly, to a hinge cup for mounting a hinge on a door of a furniture article, such as a desk of cabinet, which allows for an increased angular range of opening of the door relative to the door mounting frame of the furniture article.
BACKGROUND OF THE INVENTION
In the cabinetry industry, a typical construction feature, for example, in cabinets which are provided with doors, is a face frame on which the door is supported and hinged. The face frame members are affixed, for example, to an opening in the cabinet, and a pair of concealed hinges are affixed to an edge of one of the face frame members and the door.
A customary mounting method of affixing the concealed hinge to the face frame member utilizes a hinge mounting plate which is positioned on an edge of the face frame member and fastened to the face frame member with one or more fasteners, such as fastening screws, inserted through one or more openings in the mounting plate and into, for example, one or more corresponding pre-drilled holes in the face frame member. Alternatively, the face frame may be omitted entirely, for example, in frameless cabinets, and the hinge plate may be affixed directly to an edge of a cabinet wall member in a substantially similar way.
After mounting one hinge arm to the face frame member or cabinet wall member as described above, the hinge arm is often pivotally connected to a hinge cup which is received in a recess in the rear face of the door member, in an appropriate position to allow functional hanging of the door relative to the face frame or cabinet wall member. Such “hinge cups” are known in the art, and are disclosed, for example, in U.S. Pat. No. 5,604,956 to Grass. Such hinge cups provide a structure for pivotally connecting the hinge arm to a door member, as well as providing a recess for receiving a hinge arm when the installed door is in the closed position. Angled hinge arms may provide a certain increase in the angle of opening possible for doors using this type of hinge.
It is sometimes desirable that the angular range of opening of door be increased even further than that provided by angled hinge arms pivotally attached to conventional hinge cups. Applications which call for increased angular opening may include the installation of doors for corner cabinets, e.g. where such doors are hung as two parts hinged together.
Accordingly, it is one object of the present invention to provide a hinge cup having a structure allowing hinged doors to function with an increased angular range of opening.
SUMMARY OF THE INVENTION
It is a feature and advantage of the present invention to provide a hinge cup which is inexpensive to make, easy to use, and which enables, for example, concealed, edge-mounted type hinges to provide an increased angular range of opening for doors, such as cabinet doors.
To achieve the stated and other features, advantages and objects of the present invention, an embodiment of the present invention relates to a hinge providing increased angular opening, wherein the hinge comprises a hinge cup and a hinge arm, and the hinge cup further comprises an attachment point located proximal to a side of the hinge cup and adapted to pivotally secure the hinge arm to the hinge cup; and wherein the side of the hinge cup defines a cut-way positioned to receive the hinge arm when the hinge arm is in an open position.
Additional objects, advantages and novel features of the present invention will be set forth in part in the description which follows, and in part will become more apparent to those skilled in the art upon examination of the following or may be learned by practice of the invention.
