A gate hinge pin and strap assembly for attachment to a wooden post for supporting a gate including a J-bolt or threaded L-bolt with a metal strap affixed to the bolt between the threads and cylindrical neck portion. A bendable metal strap extends on each side of the J-bolt or threaded L-bolt. The L-shaped rod is threaded into the post until the metal strap contacts the post. Then each bolt of the metal bracket is bent around the post and screws or lag bolts are threaded through the holes and into the post to help secure the hinge to the post and to provide added support for the gate.

In one example, an apparatus includes a blow molded structure with one or more parting lines. The blow molded structure includes a body portion that is an integral part of the blow molded structure, and a pin that is integral with the body portion, and a portion of the pin is spaced apart from the body portion of the blow molded structure so that a space is defined between the portion of the pin and the body portion.

A hinge element for a large domestic appliance contains a main body as well as a functional body which includes a plastic material. Accordingly, the main body and the functional body are connected to one another non-releasably. Ideally, a large domestic appliance, in particular a large domestic refrigerator, contains a housing in which a receiving space is formed. The domestic appliance has a closure element by which the receiving space can be closed, and the hinge element hingedly attaches the closure element to the housing.

The present invention is directed to a 4-bar kinematic link component and method for forming the 4-bar kinematic link using a single rotary molding tool. The invention eliminates the need to form individual components of the bracket from several different tools, which will then requires additional assembly steps. The 4-bar kinematic link is formed from two different materials each having a different in mold shrinkage value. This allows for hinge pins to be formed through a base component in a way that will prevent sticking of the components together thereby allowing the parts to have it relative to one another using the hinge pin. The final component is a 4-bar kinematic link that can be used as a 4 bar link mechanism for providing motion.

Systems and methods of co-printing a unitary hinge are provided. The unitary hinge may be co-printed using an additive manufacturing process. The unitary hinge includes a hinge pin that is substantially cylindrical in shape. The unitary hinge also includes a knuckle which surrounds a portion of the hinge pin and is configured to be manipulated about the hinge pin. The hinge pin is fabricated in situ with the knuckle such that further assembly is unnecessary. The unitary hinge may also include retention mechanism to retain the hinge within the knuckle without substantially restricting the knuckle from being rotated about the hinge pin. The unitary hinge may further be configured with a fluid port which may, for example, be used to provide a lubricant to an area between the hinge pin and the knuckle or to vacuum powder material or debris from the area.

A hinge pin that allows for clean and convenient internal lubrication of associated door hinge assemblies, including: a head, a body, and a tip; wherein the head includes a fluid reservoir, and a fluid input aperture; wherein the body includes a first end, a second end, wherein the first end and the second end define a length therebetween, at least one fluid output aperture, a primary bore, and a secondary bore; and wherein the primary and secondary bores are positioned between the fluid input aperture and the at least one fluid output aperture, and define a pathway for fluid flow therebetween.

A method of manufacturing a door hinge, which can improve productivity by applying both metal injection molding and additive manufacturing is disclosed. The method includes: preparing a first mixture of a first metal powder and a first binder, and a second mixture of a second metal powder and a second binder; molding the first mixture into a first body including a first connection member having a first pinhole; molding the first mixture into a second body including a second connection member having a second pinhole to communicate with the first pinhole; arranging the first body and the second body to align the first pinhole and the second pinhole along an axis to form a cavity; forming a pin member with the second mixture in the cavity by adding up droplets of the second mixture in the cavity; and sintering the first body, the second body, and the pin member.

A method of manufacturing a door hinge, which can improve productivity by applying both metal injection molding and additive manufacturing is disclosed. The door hinge includes: a first body configured to include at least one first connection member in which a first pinhole is formed; a second body configured to include at least one second connection member in which a second pinhole communicating with the first pinhole is formed; and a pin member configured to be added and filled in a cavity formed by communicating the first pinhole of the first body and the second pinhole of the second body with each other so that the first body and the second body are foldably connected to each other.
