FIELD OF THE INVENTION
The invention relates generally to hinge mounting blocks and particularly to adjustable hinge mounting blocks.
BACKGROUND OF THE INVENTION
In some cases, such as in a submarine, structural posts are welded between the floors and ceilings. The areas between the posts are called “bays” and may be used to install electronic and other equipment. Doors may be mounted between the structural posts to protect the equipment and sometimes to create an air tight seal. These bays may be cooled by heat exchangers and thus, it is important to keep bays cool and not allow cool air to escape out of the bays.
A hinge block, such as one illustrated in FIG. 1, has been used to mount two doors on a single structural post. This method works well only if all the structural posts are “true” or orthogonal with respect to the floors and ceilings and simultaneously parallel to each other. If there is even a slight misalignment between two posts, installation of two doors on two bays, between three structural posts becomes difficult and laborious. Adjusting each door then requires extra labor and force which may result in damage to the hardware as well as to the doors themselves, which may become warped. Alternatives are desired.
SUMMARY OF THE INVENTION
According to an aspect of the present invention, an adjustable hinge block includes first and second complementary members each defining therein a first and a second slit respectively. The first and second members are adapted to mate with each other such that the first and second slits at least partially align with each other to define a third slit. The hinge block further includes first and second wing members protruding from the first and second members respectively such that the first and second wing members lie on opposite sides of the third slit when the first and second members mate with each other. Each of the first and second wing members defines therein a first aperture and a second aperture respectively. The adjustable hinge block also includes first and second side members, each defining therein a third and a fourth aperture respectively, such that the third and fourth apertures are adapted to align with the first and second apertures of the first and second wing members respectively.
According to an aspect of the invention, a method of installing two doors on a structural member includes a step of mounting an adjustable hinge block on the structural member. The adjustable hinge block includes first and second members, each defining therein first and second slits respectively. The first and second members are adapted to mate with each other such that the first and second slits at least partially align with each other to define a third slit. The adjustable hinge block further includes first and second wing members protruding from the first and second members respectively such that the wing members lie on opposite sides of the third slit when the first and second members mate with each other. Each of the first and second wing members defines therein a first and a second aperture respectively. The method then includes a step of connecting the first and second complementary members to the structural member using a fastener, which fastener passes through the third slit. The method includes the step of connecting the first and second side members to the first and second members using a fastener. The first and second side members are adapted to provide symmetrical and asymmetrical connections with respect to the first and second complementary members. The method further includes the step of connecting a door to each of the first and second side members using a fastener.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
The invention and its various embodiments can now be better understood by turning to the following detailed description of the exemplary embodiments which are presented as illustrated examples of the invention defined in the claims. It is expressly understood that the invention as defined by the claims may be broader than the illustrated embodiments described below. It is to be understood that the figures and descriptions of the present invention have been simplified to illustrate elements that are relevant for a clear understanding of the present invention, while eliminating, for purposes of clarity, many other elements found in typical hinge mounting blocks. However, because such elements are well known in the art, and because they do not facilitate a better understanding of the present invention, a discussion of such elements is not provided herein. The disclosure herein is directed to all such variations and modifications known to those skilled in the art.
Referring initially to FIG. 1, a front view of a prior art hinge block 100 is illustrated. Hinge block 100 includes a machined block 110, generally made of metal. A longitudinal slit 120 is formed generally in the central part of block 110. A series of apertures 130 are made in each corner of block 110. Apertures 130 are adapted to receive fasteners. Hinge pins (not shown) and door closure hardware (not shown) are mounted to hinge block 100 using fasteners (not shown).
Referring now to FIG. 2, a prior art method of mounting two doors 220 on a single structural post 210 using hinge block 100 is described. Occasionally, each door 220 will be connected to both the structural posts 210 on either side of door 220. It will be appreciated by one of ordinary skill in the art that a slight misalignment between first post 210 and first door 220 will make the alignment of first door 220 and second post 210 difficult and such misalignment will propagate and even amplify as subsequent doors 220 are sequentially connected to subsequent posts 210.
Referring now to FIG. 3, a pair 300 of complementary hinge block members 310a, 310b is illustrated. Each member 310a, 310b has a generally planar structure 315a, 315b and a projection 317a, 317b generally perpendicular to structure 315a, 315b, respectively. In an exemplary embodiment, structure 315a, 315b is generally rectangular in shape. Other shapes are also possible. Each planar structure 315a, 315b has a longitudinal slit 320a, 320b respectively defined therein. The term “longitudinal” denotes a shape that has a high length to width ratio. In an exemplary embodiment, slits 320a, 320b has beveled edges. Projections 317a, 317b have generally half the width of structures 315a, 315b. Each member 310a, 310b has a wing member 330a, 330b projecting generally orthogonally from structures 315a, 315b, respectively. In the illustrated embodiment, wing members 330a, 330b are generally square in shape; however, other shapes are also possible. Each wing member 330a, 330b has through apertures 340 defined therein. In the illustrated embodiment, each wing member 330a, 330b has two (2) apertures 340 each. In other embodiments, wing members 330a, 330b may have more or less than two (2) apertures. Apertures 340 are adapted to receive fasteners such as screws and bolts. Apertures 340 may or may not have internal threads (not shown) for engaging with fasteners (not shown). Members 310a, 310b are adapted to mate with each other such that structure 315a is in sliding contact with projection 310b and structure 315b is in sliding contact with projection 310a. When members 310a, 310b mate with each other, slits 320a, 320b at least partially align with each other to define a single slit 520 (of FIG. 5).
Referring now to FIG. 4, a side member 400 according to an embodiment of the invention is illustrated. Side member 400 has an upper surface 410 and a lower surface 420. An indentation 430 is formed in the lower surface 420. Indentation 430 is generally dimensioned to mate with wing member 330a or 330b. Side member 400 has through apertures 440 defined therein, which apertures 440 open in indentation 430. Apertures 440 are adapted to mate with apertures 340, but are wider than apertures 340. In an exemplary embodiment, apertures 440 are generally oval along the width of side member 400, whereas apertures 340 are generally circular. In an exemplary embodiment, apertures 440 have beveled edges. In the illustrated embodiment, side member 400 has two (2) apertures 440. In other embodiments, apertures 440 may be more or less than two (2) in number, generally but not necessarily being the same in number as apertures 340 in each of wing members 330a, 330b. Side member 400 also has other through apertures 450 defined therein on either side of apertures 440. Apertures 450 may or may not be of the same size and are adapted to receive various fasteners such as screws and bolts. Apertures 450 may or may not have internal threads (not shown) for engaging with fasteners (not shown). In the illustrated embodiment, apertures 450 are in clusters of three (3), generally in a triangular pattern. In other embodiments, apertures 450 may have different pattern and be more or less than three (3) in number. In an exemplary embodiment, side member 400 has a length generally equal to that of members 310a, 310b. In another embodiment, side member 400 may have a length shorter or longer than that of members 310a, 310b.
Referring now to FIG. 5, an assembled hinge block 500 according to an embodiment of the invention is illustrated. Complementary members 310a, 310b mate with each other to form a single slit 520. In the illustrated embodiment, member 310a is illustrated slightly offset in longitudinal direction with respect to member 310b to illustrate the concept of adjustment in a longitudinal direction available in the exemplary adjustable hinge block 500 of the present invention. Arrows 530 illustrate a direction in which a certain flexibility or degree of adjustment is available for arranging members 310a, 310b relative to each other. Two side members 400a, 400b are positioned in each side of slit 520, such that apertures 440 generally align with apertures 340 of wing members 330a, 330b respectively. Indentations 430 (of FIG. 4) of side members 400a, 400b align and mate with wing members 330a, 330b respectively. Apertures 440 are generally wider than apertures 340 generally in a direction transverse to longitudinal slit 520. Because of extra width of apertures 340, a certain flexibility or degree of adjustment is available in the direction shown by arrows 540. Slight angular adjustment may also be made as shown by arrows 550 because apertures 440 are slightly bigger than apertures 340. FIG. 6 illustrates an isometric view of the assembled adjustable hinge block of FIG. 5.
Referring now to FIGS. 7A-7B, a drop behind shim 700 as per an embodiment of the invention is illustrated. Shim 700 has a generally thin planar metal base 710. Two planar prongs 720, 730 extend from base 710 and define a gap 750. An angular projection 740 projects from base 740, angling away from the plane of base 710 and prongs 720, 730.
Referring now to FIG. 8, a method of using drop behind shim 700 is illustrated. Shim 700 may be used for leveling hinge block 500 mounted on a structural post (not shown). Occasionally, the need to level block 500 may be realized after fasteners 810 have been installed to mount block 500 to a structural post. Shim 700 with two prongs 710, 720 (of FIG. 7) facilitates such leveling without having to remove fasteners 810. Shim 700 may be inserted in a slight gap between block 500 and a structural post (not shown) such that prongs 710, 720 each slide on each side of fasteners 810.
Referring now to FIG. 9, a method of installing two doors 220a, 220b to a single structural post 210b using an exemplary embodiment of adjustable hinge block 500 is illustrated. The term “door” includes, by way of example only and not limited to, any structural element that is movable barrier for opening and closing an entranceway, cupboard, cabinet, or the like, commonly turning on hinges. Complementary members 310a, 310b are mated with each other and combinedly mounted to structural post 210b using fasteners 910. Fasteners 910 pass through longitudinal slit 520. Members 310a, 310b may be adjusted slightly in a longitudinal direction based on the height requirement of doors 220a, 220b. Side members 400a, 400b are mounted to wing members 330a, 330b (of FIG. 5), respectively, using fasteners 920.
A hinge pin 930 is used to mount door 220b to structural post 210b via hinge block 500. Hinge pin 930 is mounted to side member 400a using fasteners (not shown). Hinge pin 930 allows door 220b to open and close. Door 220a, on other hand, is locked to structural post 210b using an L-bracket 940. L-bracket 940 is mounted to block 500 using fasteners 950. Fastener 950 may, by way of example only, a thumbscrew. L-bracket 940 is installed on door 220a using fasteners 960.
If there is a slight misalignment resulting from mounting (not shown) of door 220a to post 210a, adjustable hinge block 500 may be adjusted to mount door 220a to post 210a, without propagating the misalignment to the mounting of door 220b to post 210b. If there is no misalignment between posts 210a, 210b, 210c and doors 220a, 220b, side members 400a, 400b will be symmetrical with respect to complementary members 310a, 310b. If there is some misalignment, side members 400a, 400b will be asymmetrically connected with respect to complementary members 310a, 310b and thus compensate for the misalignment.
Although the present invention has been set forth in terms of the exemplary embodiments described herein, it is to be understood that such disclosure is purely illustrative and is not to be interpreted as limiting. Consequently, without departing from the spirit and scope of the invention, various alterations, modifications, and/or alternative applications of the invention will, no doubt, be suggested to those skilled in the art after having read the preceding disclosure. Accordingly, it is intended that the present invention be interpreted as encompassing all alterations, modifications, or alternative applications as fall within the true spirit and scope of the invention.
