Abstract

A hinge assembly for artificial Christmas trees that allows for the collapse of the tree without danger of the hinge binding or pinching materials in contact with the hinge and which is well suited to fabrication by mass production techniques.

Claims

1. A hinge assembly for the connection of limbs to the trunk of an artificial tree comprising

a hollow cylindrical retaining collar having a central axis, connecting means to attached said collar to said trunk, a plurality of radial brackets having a first end attached to said collar and a second end surface, said bracket having parallel opposed sides attached to and extend outwardly from said collar and having a bracket aperture extending through said parallel opposed sides, with the axis of said bracket aperture being substantially orthogonal to the axis of said collar,

a plurality of arms for connecting said limbs to said brackets, each of said arms having a first portion forming a U-shaped channel of sufficient width to engage said second end of said brackets,

said first portion having co-axial apertures so located that when aligned with the bracket apertures will insure alignment between said arm and said bracket, said first portion further having a curved end surface, the major portion of which is convex but terminating in a concave segment said concave segment and said second end surface cooperating to form a divergent angle therebetween as said arm is moved in a downward direction,

a second portion adapted to hold said branch,

2. A hinge assembly for the connection of limbs to the trunk of an artificial tree as described in claim 1, wherein said brackets are U-shaped channels having both flat sides of said channel parallel to axis of said collar.

3. A hinge assembly as described in claim 1, wherein said pivoted means is a removable U-shaped rod with one substantially straight leg of said rod passing through said apertures of said arm and bracket and serving as the pivotal element for the hinge assembly, with a second leg passing over the exterior surface of said arm and having an inwardly bent portion between the said arm and the free end of said second leg, whereby the pressure of said second leg or said arm secures said U-shaped rod.

4. A hinge assembly as described in claim 1, wherein said connecting means is a metal tab forming an integral portion of said collar.
