The present invention relates to the field of gate hinges, especially those made for use on wooden posts.
Gate hinges have been in use for hundreds of years. Gates historically have been made of wooden slats nailed or bolted together and therefore tend to be quite heavy. A wooden gate that is sixteen feet long and which is four and one half feet tall can weigh more than one hundred pounds. Such a gate causes a great deal of strain on a post and on the hinges which must support the weight of the post plus the stresses put on the gate when swinging open and closed.
Typical farm gate hinges and some garden or yard gate hinges include two parts, a looped member which is fastened with the loop near one vertical edge of the gate, and a threaded hinge pin wherein one leg is threaded into a wooden post and wherein the other leg extends either upward or downward and wherein the loop of the loop member is slipped down over the upward or downward extending leg of the threaded hinge pin, as shown in
The most stressful position for that portion of gate hinge which is directly connected to the post is that in which the gate is wide open. As shown in
U.S. Pat. No. 8,800,110 for GATE HINGE by Stephenson which issued on Aug. 12, 2014 teaches a hinge including an L-bolt which is threaded and held within a plate by a nut on either side of the plate and wherein the plate has holes through which lag bolts are driven into the wooden post.
U.S. Pat. No. 1,188,302 for GATE HINGE by Mohns which issued on May 20, 1916 teaches an L-bolt cast with a plate with screw holes and a threaded rod which pierces and is threaded into the wooden post, after which a bracket is attached to either side of the plate by hooks and is then bolted around the fence post.
As shown in the attached figures, the threaded shanke portion of the hinge pin is rotatably inserted into a horizontal hole drilled in the post. A gate usually swings on a pair of spaced apart aligned hinge pins comprising a threaded shank having a distal point and a neck extending to an upturned post comprising a smooth rod or pin post bent at a 90 degree angle with respect to the shaft wherein a horizontal loop or sleeve of a gate post pin receiver is mounted onto a gate and the loop or sleeve extending therefrom mounts onto the pin post and rests on a circumferential lip or shoulder formed above the 90 degree elbow.
Because the weight of the gate pulls on the top hinge and pin, it tends to pull from the post and over time become loose so that the hinge pin rotates and the sleeve supporting the gate slips off of the top pin.
The present invention utilizes a bendable support strap which is welded onto the post pin between the shank threads and the neck extending therefrom. The formable support strap comprises a generally flat bendable support strap of material welded onto the pin at a point where the threads of the shank stop. The strap must be flat in order to screw the hinge pin into the hole in the post until the straps abut the post, whereby the straps are bent around the post and nailed or screwed into the post on either side of the hinge pin providing lateral support to the pin and preventing rotation or twisting of same.
In accordance with the present invention, there is provided a two part gate hinge comprising, consisting of, or consisting essentially of a loop member and an Threaded hinge pin. The L-shaped member includes a long threaded leg about eight to twelve inches long, a 90 degree elbow, a short smooth leg about two and one half inches long, and a long rectangular metal strap about twelve to sixteen inches long, about one and one half to two inches wide and about one eighth to three sixteenths inch thick. The metal strap has a first hole formed therein in a center thereof sized to receive the threaded leg which passes through the first hole and is permanently fixed to the metal strap near the elbow about one and one half inches from the elbow at right angles with the metal strap. The threaded leg has threads formed thereon from the pointed free end to the junction of the threaded leg with the metal strap. The shorter leg of the Threaded hinge pin includes a flat metal washer permanently fixed near the elbow and about two inches from a free end of the shorter leg with a top surface of the washer perpendicular to the shorter leg. The metal strap has at least four holes formed therein, each of the four holes being within about one half inch of each corner. The metal strap is capable of being bent and formed around a partial circumferential surface of a fence post. The loop member comprises a long flat metallic rectangular member about eighteen inches long and about two inches wide, with one end turned back on itself, forming a loop capable of rotatably receiving the short leg or stud of the threaded hinge pin. The loop member has a plurality of holes formed therein for insertion of screws or bolts for fastening the loop member to a vertical edge of a gate.
It is an object of this invention to provide a two part gate hinge including a loop member which is attached to a vertical edge of the gate and an Hinge pin which is threaded into a post with and upward extending leg on which to slip the loop member, and wherein the Hinge pin includes a strap of metal which extend to the left and right of the threaded leg and which includes holes for inserting and threading of screws or lag bolts into the post to brace the Hinge pin from movement to the left or right.
Other objects, features, and advantages of the invention will be apparent with the following detailed description taken in conjunction with the accompanying drawings showing a preferred embodiment of the invention.
A better understanding of the present invention will be had upon reference to the following description in conjunction with the accompanying drawings in which like numerals refer to like parts throughout the views wherein:
The terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. As used herein, the singular forms “a,” “an,” and “the” may be intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms “comprises,” “comprising,” “including,” and “having,” are inclusive and therefore specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order discussed or illustrated, unless specifically identified as an order of performance. It is also to be understood that additional or alternative steps may be employed.
When an element or layer is referred to as being “on,” “engaged to,” “connected to,” or “coupled to” another element or layer, it may be directly on, engaged, connected or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly engaged to,” “directly connected to,” or “directly coupled to” another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
Although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as “first,” “second,” and other numerical terms when used herein do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example embodiments.
Spatially relative terms, such as “inner,” “outer,” “beneath,” “below,” “lower,” “above,” “upper,” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. Spatially relative terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the example term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
As used herein, the term “about” can be reasonably appreciated by a person skilled in the art to denote somewhat above or somewhat below the stated numerical value, to within a range of +10%.
The present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

As shown in the
As shown in the
The L-shaped threaded hinge pin member 10 includes a threaded leg 12, a long rectangular metal strap 14 affixed on the threaded leg near the elbow 16 at right angles with the threaded leg, elbow which is 90 degrees, and a shorter upturned arm or stud 20 which is about two and one half inches long. The L-shaped member may comprise a integral formed member hinge pin 60 typically including a pointed tip 61 extending from a threaded longitudinal body 62 having a short upturned cylindrical shaft or stud 20 extending therefrom at a right angle usually with an enlarged collar 63 portion separating the arm and threaded longitudinal body, whereby the collar provides a support surface for rotational movement of a gate hinge thereon. The proximate end of the threaded section may be welded to the strap or to a stationary threaded nut 65 affixed to the strap by welding or other means.
The L-shaped member may also comprise an “L-bolt” having threaded longitudinal body with a short cylindrical arm or stud extending therefrom at a right angle including at least one and preferably two threaded nuts with optional washers for tightening the threaded member after insertion into a bore hole of a post. The threaded leg may be threaded from the pointed end 11 all the way to the elbow 16 but is preferably threaded only to about where the junction of the threaded leg is with the metal strap. The shorter leg 20 of the threaded hinge pin includes an optional flat metal washer or a collar 18 affixed near the elbow 16 and about two inches from the free end of the shorter leg 20. The top surface of the washer 18 is perpendicular to the shorter leg 20. Preferably, the proximate stationary nut may be permanently affixed to the outer surface of a strap preventing rotation of the nut and strap.
After insertion a selected depth through a bore hole in a post the threaded longitudinal member maybe tightened to the post by rotating the stud or a second threaded nut 66 and optional washer in cooperative engagement with the distal end of the threaded shaft 12 whereby the stationary strap nut is held while the second nut is rotated tightening the hinge pin against the post.
The longitudinal strap 14 is composed of a bendable metal or plastic material having memory allowing the strap to be bent and curved around a post. It is necessary that the metal strap is formable around the curved surface of a fence post. The pointed end 11 of the threaded leg passes through a hole in the center of the long metal strap 14 which is then permanently attached to the threaded leg about one and one half to two inches from the elbow 16. There is a selected number of smaller attachment holes and preferably at least four holes in the strap 14. It is contemplated that spikes 13 may also protrude from the inner surface of the straps for cooperative engagement with the posts in order that the spikes may be driven into the posts to prevent rotation of the straps on the post.
The foregoing detailed description is given primarily for clearness of understanding and no unnecessary limitations are to be understood therefrom, for modification will become obvious to those skilled in the art upon reading this disclosure and may be made without departing from the spirit of the invention and scope of the appended claims. Accordingly, this invention is not intended to be limited by the specific exemplification presented herein above. Rather, what is intended to be covered is within the spirit and scope of the appended claims.
This application claims priority from U.S. Provisional Application Ser. No. 62/678,553 filed on May 31, 2018 and is incorporated by reference herein in its entirety.
