DETAILED DESCRIPTION

[0021] Before describing several exemplary embodiments of the disclosure, it is to be understood that the disclosure is not limited to the details of construction or process steps set forth in the following description. The disclosure is capable of other embodiments and of being practiced or being carried out in various ways.

[0022] The term horizontal as used herein is defined as a plane parallel to the plane or surface of a floor, a deck or a deck of a boat, regardless of its orientation. The term vertical refers to a direction perpendicular to the horizontal as just defined. The term non-horizontal includes planes that are at 20 degrees to 120 degrees from a horizontal plane, including, but not limited to vertical. The phrases side mount and side mounted refer to a table leg that is affixed to a non-horizontal surface of a room, a deck, a vehicle, a boat or a motorhome. For example, a side mounted or socket retainer is not affixed to the deck or gunwale of a boat but instead is affixed to a sidewall surface of a boat such as a wall, a coaming or other non-horizontal surface. Terms, such as above, below, bottom, top, side (as in sidewall), higher, lower, upper, over, and under, are defined with respect to the horizontal surface as shown in the figures.

[0023] The term on indicates that there is direct contact between elements. The term directly on indicates that there is direct contact between elements with no intervening elements.

[0024] Referring now to FIGS. 2-13 in one or more embodiments, a hinge assembly 100 comprises an a first portion 102 comprising a central bore 120, a middle portion 104 comprising a central bore 122, and a second portion 106 comprising a central bore 124. The hinge assembly 100 and each of the first portion 102, the middle portion 104, and a hinge rod 108, which is configured to be received within the central bores 120, 122, and 124 each define a length L. The hinge assembly 100 further comprises the hinge rod 108, which is configured to be received within each of the central bores 120, 122 and 124.

[0025] The second portion 106, the middle portion 104 and the first portion 102 are configured to be mounted to the hinge rod 108 through the central bore 124 of the second portion 106, the central bore 122 of the middle portion 204 and the central bore 120 of the first portion 102. The central bore 124 of the second portion, the central bore 122 of the middle portion 104 and the central bore 120 of the upper first are each configured to receive the hinge rod 108, so that the first portion 102 and the middle portion 104 rotate freely around the hinge rod 108. In some embodiments, the second portion 106 is affixed to the hinge rod 108, for example, by a set screw (not shown).

[0026] The middle portion 104 comprises middle portion elongate fingers 110 and middle portion elongate grooves 112. The middle portion elongate fingers 110 are separated by the middle portion elongate grooves 112. The middle portion elongate fingers 110 and middle portion elongate grooves extend along a length L of the middle portion 104. The first portion 102 comprises first portion elongate fingers 114 separated by first portion elongate grooves 116. In some embodiments, the orientation of the first portion 102 and the second portion 106 are reversed. Stated another way, the orientation of the assembly 100 may be rotated 180 degrees about an x-y plane so that the first portion 102 is positioned beneath the middle portion 104. The first portion elongate grooves 116 in some embodiments are complementary to the middle portion 104 elongate fingers 110. Likewise, in some embodiments, the first portion elongate fingers 114 are complementary to the middle portion elongate grooves 112. As used herein, complementary refers to the fingers of one part fitting within the grooves of the other part.

[0027] Accordingly, in the embodiment shown, the middle portion 104 includes the elongate fingers 110 extending upwardly separated by the elongate grooves 112, and the first portion 102 is an upper portion and comprises the complementary elongate grooves 116 separated by first portion elongate fingers 114 that fit within the middle portion elongate grooves 112. Therefore, in the embodiments shown, the hinge assembly 100 is oriented so that the first portion 102 is located above the middle portion and the second portion 106 is located below the middle portion. However, this orientation can be reversed so that hinge assembly 100 is oriented so that the first portion 102 is located below the middle portion 104 and the second portion 106 is located above the middle portion.

[0028] The complementary elongate grooves 116, as shown in FIG. 4 have a taper T defining an angle with respect to a tangent that intersects with a perpendicular line 113 that is perpendicular to a bottom surface 115 of the first portion 102. The elongate fingers 110 have a similar taper T (now shown) to the taper T of the complementary elongate grooves 116. It will be appreciated that this taper T on the complementary elongate grooves 116 and the elongate fingers 110 are configured so that when a gate 150 (shown in FIG. 13) is mounted to the hinge assembly 100, the complementary elongate grooves 116 bottom out in the elongate fingers 110 for a snug and firm fit that prevents the hinge assembly 100 and the gate from rattling.

[0029] In some embodiments, the first portion 102 and the second portion 106 are fixedly mounted to the hinge rod 108 and the middle portion 104 is slidably mounted to the hinge rod 108. In some embodiments, the elongate fingers 110 of the middle portion 104, and the complementary elongate grooves 116 interlock with each other creating a complementary pair when the hinge assembly 100 is in a fixed position under a force of gravity.

[0030] In some embodiments (not shown), the complementary elongate grooves 116 are on a middle portion 104, and the elongate fingers 110 are on one of the first portion 102, which interlock with each other creating a complementary finger/groove pair when the hinge is in a fixed position under a force of gravity. The interlocking of the finger/groove pair is under a force of gravity according to one or more embodiments, and no additional biasing by a spring, or any other force is required to secure the hinge assembly in place.

[0031] In some embodiments, there are least 2 and less than 10 complementary finger/groove pairs. In other embodiments, there are from 2-3, 2-4, 2-5, 2-6, 2-7 or 2-8 finger/groove pairs.

[0032] In some embodiments, the taper T is in a range of from 1 to 15 degrees, 1 to 14 degrees, 1 to 13 degrees, 1 to 12 degrees, 1 to 11 degrees, 1 to 10 degrees, 1 degree to 9 degrees, 1 to 8 degrees, 1 to 7 degrees, 1 to 6 degrees, 1 to 5 degrees, 1 to 4 degrees or 1 to 3 degrees. In specific embodiments, the taper T is in a range of from 2 to 12 degrees, 2 to 11 degrees, 2 to 10 degrees, 2 to 9 degrees, 2 to 8 degrees, 2 to 7 degrees, 2 to 6 degrees, 2 to 5 degrees, 2 to 4 degrees, 2 to 3 degrees, 5 to 12 degrees, 5 to 11 degrees, 5 to 10 degrees, 5 to 9 degrees, 8 to 12 degrees, 8 to 11 degrees or 8 to 10 degrees. When the taper is too large, the interlock of fingers and complementary elongate grooves may not be optimal, which can cause the hinge to rattle because the fingers fit too loosely within the complementary elongate grooves. In one or more embodiments, the taper of the elongate grooves 112 of the middle portion 104 is equal to the taper T of the elongate fingers 114 of the first portion 102. Similarly, the taper T of the elongate fingers 110 of the middle portion 104 is equal to the taper T of the elongate grooves 116 of the first portion 102.

[0033] In one or more embodiments elongate fingers 110 have a length to width aspect ratio in a range of from 2.5:1 to 10:1, for example 2.5:1 to 9:1, 2.5:1 to 8:1, 2.5:1 to 7:1, 2.5:1 to 6:1, 2.5:1 to 5:1, 2.5:1 to 4:1 or 2.5:1 to 3:1. The length to width is optimized to provide a stable and snug fit and interlock of the elongate fingers 110 and the complementary elongate grooves 116. In one or more embodiments, the first portion, the middle portion and the third portion comprise solid cast metal material.

[0034] In some embodiments the middle portion further comprises polymeric bushings, an upper bushing 118a and a lower bushing 118b. The polymeric bushings of some embodiments is made from bronze metal, paraformaldehyde (sold under the name Delrin) or nylon. In some embodiments, the polymeric bushings are fitted within pockets 121a and 121b shown in FIG. 9.

[0035] Referring now to FIG. 13, a gate assembly is shown as comprising the hinge assembly 100 as shown and described herein according to one or more embodiments and affixed to a gate 150, wherein the gate is secured to at least one of the first portion 102, the middle portion 104, and the second portion 106 of the hinge assembly. In some embodiments, the gate is secured to the first portion 102. In some embodiments, the gate is secured to the second portion 106. In some embodiments, the gate is secured to the middle portion 104. In the non-limiting embodiment shown, the middle portion 104 is affixed to a mounting fixture, which is configured to be mounted to a member defining an opening, for example, a stud of a building structure, a fence post, a wall or any other suitable structure. It will be understood that the embodiment in FIG. 13 showing the gate 150 is just one example of a barrier to entry. In other embodiments, the barrier to entry can be a door of structure, a cabinet door for a cabinet that is used in a building or a vehicle.

[0036] The gate 150 can be secured by suitable bolts, screws, tack weld or any other suitable securement method. The various components of the hinge assembly other that the bushings may be made from a suitable metal such as aluminum or stainless steel.
