Description
INTRODUCTION

Hinges are used to move pivoting elements, such as windows and doors, between a closed position and a selected open position. Often, however, the moved window or door (commonly referred to as a panel), may continue to pivot to a different position due to a skewed panel or panel frame (i.e., a window frame or door frame) or other structural condition. Additionally, the panel may also move when acted upon inadvertently by an outside force, such as a gust of wind or a pet brushing against the panel. To minimize further pivoting, a hinged panel may be partially secured by casement hardware (in the case of a window) or a door stop (in the case of a door). These pivot limiting devices may be unsightly or require additional hardware.

DETAILED DESCRIPTION


FIGS. 1 and 2 depict a positionable hinge 10. The hinge 10 includes two sections 100, 200. In the depicted embodiment, the first section 100 is an upper section and the second section 200 is a lower section. Each section 100, 200, includes a leaf 102, 202 and a hinge barrel 104, 204. Each leaf 102, 202 defines one or more openings 106, 206. In the depicted embodiment, the openings 106 in the first leaf 102 may be used to moveably secure the leaf 102 within an adjustable hinge receiver R. The openings 206 may be used to secure the leaf 202 to a respective panel or jamb with screws, bolts, or other fasteners. Additional elements of an adjustable hinge, such as that depicted in FIG. 2, are described in U.S. Published Patent Application No. 2010/0242227, the disclosure of which is hereby incorporated by reference herein in its entirety. A pin 12 pivotably secures the two sections 100, 200, at their respective hinge barrels 104, 204. The pin 12 is substantially aligned with the pivot axis A formed by each hinge barrel 104, 204. The pin 12 may include a cap 14 to prevent fall-out of the pin 12, or locking caps may be used with a capless pin to secure the pin in place to prevent fall-out or back-out thereof. Each barrel 104, 204 may also include a bushing 108, 208 located at the barrel interface I. The second bushing 208 may include a keyway 208c configured to mate with a slot 204b on the second barrel 204. A similar keyway is located on the first bushing 108. This configuration aids in aligning the projections 110 and indentations 112 described below. The barrel interface I comprises opposed textured mating surfaces, whether or not bushings are utilized, to hold the hinge in a desired position.



FIG. 3 depicts a bushing system B that may be utilized in the positionable hinge described herein. In the depicted embodiment, the first bushing 108 includes a plurality of projections 110 that project substantially outward from an interface surface 112. The side 112a of the bushing opposite the interface surface 112 contacts an end surface 104a of the first barrel 104. Corresponding indentations 210 defined by the interface surface 212 are present on the second bushing 208. Additionally, the side 212a of the bushing opposite the interface surface 212 contacts an end surface 204a of the second barrel 204. The indentations 210 may be configured to substantially match the three-dimensional shape profile of the projections 110, or may simply be openings or gaps formed in the interface surface 212 to receive the projections 110. In certain embodiments, the projections and indentations may be formed directly in the end surfaces 104a, 204a of the respective barrels 104, 204 and no bushings may be utilized. This may increase friction as the hinge is pivoted, but may be acceptable for hinges that are utilized for pivoting of lightweight panels and/or those hinges that are formed of appropriate materials.



FIGS. 4-6 depict various embodiments of bushing systems may be utilized in a barrel interface I. The elements of the embodiment depicted in FIG. 4 are described above. FIG. 5 depicts bushings 108a, 208a, each having a serrated interface surface 112a, 212a. FIG. 6 depicts bushings 108b, 208b, each having a crenellated interface surface 112b, 212b. In these two embodiments, the interface surfaces of both bushings each form substantially similar or matching opposed textured mating surfaces. Again, as described above, any of the opposed textured surfaces may be formed directly in opposed surfaces of the barrels, if no bushings are used. In another embodiment, depicted in FIG. 4, first bushing 108 includes a number of bores 114 that each include a spring 114a. In this embodiment, interface surface 112 may be discrete from the first bushing 108. The projections 110 in this case may be ball bearings or similar elements that are biased into an projected position by the spring 114a located thereunder. The interface surface 112 may then be secured to the first bushing 108 to hold these spring-loaded projections 110 in position, allowing only for substantially vertical movement thereof. The interface surface 112 may be secured to the first bushing 108 with an interference fit or adhesive. Such a spring-loaded embodiment may provide additional holding force which may be desirable for certain applications. In another embodiment, a substantially circular leaf spring may be installed in a race within the first bushing 108 to bias a number of projections 110.


The profiles of the projections and indentations used in the opposed textured mating surfaces may be any shape useful for holding the hinge in place, while still allowing movement of the hinge upon application of a sufficient force. Perspective views of various projections are depicted in FIGS. 7A-7H. In each figure, the projection 110 projects from the interface surface 112. Exemplary projection shapes include a spherical cap (FIG. 7A), as depicted also in FIGS. 1-4, a hemisphere (FIG. 7B), a pyramid (FIG. 7C), a cone (FIG. 7D), a cylinder (FIG. 7E), a frustum (FIG. 7F), a torus (FIG. 7G), and a prism (FIG. 7H). In sum, the projections may correspond to any portion of any geometric shape. Additionally, the projections may be any shape, not just the defined geometric shapes listed above. The mating indentations for each of these shapes may correspond directly to the projection shape. Alternatively, an indentation may be a channel formed radially in the bushing, or may be an indentation of any shape or size to accommodate the projection.


Any number of projections and indentations may be utilized in the opposed textured mating surfaces, depending on the application. In some embodiments, the number of projections may correspond directly to the number of indentations, or the number of indentations may exceed the number of projections. An equal number of projections and indentations may be desirable, however, for proper load balancing of the projections as they are rotated against the interface surface of the second bushing from a first position to a second position. In certain embodiments, a first bushing having a single projection may be used with a second bushing having multiple indentations. Additionally, the number of projections/indentations may also be limited by the size of the bushings or hinge barrels (if formed on the ends of the barrels themselves). Regardless of the number of projections and indentations utilized, a hinged panel utilizing the positionable hinge disclosed herein generally will be held in place as a projection engages with a corresponding indentation (or, in the case of the serrated and crenellated surfaces depicted in FIGS. 5 and 6, as those matching surfaces mate). The generally low profile of the textured surfaces, however, will allow the hinge to be pivoted if acted upon by a sufficient force. An applied force of sufficient magnitude will rotate the surfaces out of a mating position (causing slight axial movement of, in this case, the first hinge section relative to the second hinge section), until the surfaces reengage in a different position.


The materials utilized in the manufacture of the hinge 10 may be those typically utilized for hinge manufacture, e.g., zinc, steel, brass, stainless steel, etc. Material selection for most of the components may be based on the proposed use of the hinge 10. Appropriate materials may be selected for hinges used on particularly heavy door panels, as well as on hinges subject to certain environmental conditions (e.g., moisture, corrosive atmospheres, etc.). For particularly light-weight door panels (for example, cabinet door panels), molded plastic, such as PVC, polyethylene, etc., may be utilized for the various components. Nylon, acetal, TeflonĀ®, or combinations thereof may be utilized for the bushings to reduce friction, although other low-friction materials are contemplated. Threaded or press fit metal or nylon caps to secure the pin 12 in place also may be used.


The terms first, second, upper, lower, top, bottom, panel, jamb, etc., as used herein, are relative terms used for convenience of the reader and to differentiate various elements of the hinge 10 from each other. In general, unless otherwise noted, the terms are not meant to define or otherwise restrict location of any particular element. For example, the first hinge section 100 may be secured to the panel and the second hinge section 200 may be secured to the jamb, or vice-versa. Alternatively, the hinge 10 could be used with the barrels 104, 204, and pin 12 oriented horizontally. Additionally, either leaf may also form multiple barrels, if desired for a particular application. Such an application, however, would likely require additional spacing at the barrel interfaces to allow for axial movement of the barrels as the opposed textured mating surfaces engage and disengage. In such an embodiment, the specialized bushings described herein may be used on one barrel interface, with flexible bushings used between the remaining barrel interfaces, to allow for axial movement thereof.


While there have been described herein what are to be considered exemplary and preferred embodiments of the present technology, other modifications of the technology will become apparent to those skilled in the art from the teachings herein. The particular methods of manufacture and geometries disclosed herein are exemplary in nature and are not to be considered limiting. It is therefore desired to be secured in the appended claims all such modifications as fall within the spirit and scope of the technology. Accordingly, what is desired to be secured by Letters Patent is the technology as defined and differentiated in the following claims, and all equivalents.
