Abstract

An artificial Christmas tree for quick folding and display comprises a hollow trunk having reinforced ribs integrally formed along the inner wall within the hollow section and it is erected and mounted on a base support, with a plurality of forked branch-coupling members fitted around various places of the trunk at predetermined levels. Each of the forked branch-coupling members includes a lock ring fitted around the trunk, a lower branch ring coupled with the lock ring, a fastening ring engaged with the upper end of the lock ring, an upper branch ring coupled with both the lower branch ring and the fastening ring, which can be turned for making the adjustment, and a pivotable joint pivotally connected to the upper branches for accommodating the twigs, which can be folded against the trunk for storage or rapidly unfolded for display through pivotal turning of the pivotable joint.

Claims

1. An artificial Christmas tree for quick folding and display having a detachable base support and a tree-top cluster and twigs for display, comprising in combination;

a hollow trunk with reinforced ribs integrally formed along the inner wall of said hollow trunk;

a plurality of forked branch-coupling members fitted around said trunk at predetermined levels; and

straight joint means pivotally connected to said forked branch-coupling members for supporting the twigs, so that, by moving said forked branch-coupling members around said trunk, display patterns of said tree can be easily adjusted, and, by pivoting said joint means, said twigs may be folded against said trunk for easy storage and packing;

each said forked branch-coupling members comprising a lock ring having an annular flange and thread means at one end thereof;

a lower branch ring having at least one strut socket formed at the upper end and obliquely extending outwardly therefrom disposed around said trunk with the lower end abutting against the annular flange of said lock ring;

a fastening ring having an axial opening thereof fitted around said trunk with the lower and abutting against the upper end of said lock ring; and

an upper branch ring having at least one strut socket formed at the lower portion and obliquely extending outwardly therefrom corresponding to the positions of the strut socket of said lower branch ring; and

thread means provided in the lower end fitted aroung said trunk by engaging the lower portion in the inner rim of said lower branch ring and being connected to said lock ring through cooperating thread means, so that, by turning said lock ring, said branch-coupling members can easily be moved around said trunk for adjusting the display pattern of said tree as may be desired.

2. An artificial Christmas tree as claimed in claim 1, wherein said strut socket of said lower branch ring has an axial sliding slot formed therein and a flute provided at the lower end communicating with said sliding slot.

3. An artificial Christmas tree as claimed in claim 1, wherein said strut socket of said upper branch ring has an axial open slot formed therein and a notch provided at the lower end communicating with said open slot.

4. An artificial Christmas tree as claimed in claim 1, 2, or 3, wherein said strut socket of said upper branch ring corresponds to the strut socket of said lower branch ring for defining a retaining socket and a mounting socket thereat.

5. An artificial Christmas tree as claimed in claim 4, wherein said straight joint means comprises;

a joint body;

an elongated socket axially formed in said joint body for receiving the twigs thereof; and

a pivotal rod-like axle integrally provided at one end thereof and movably connected to said mounting socket defined by said lower branch ring and said upper branch ring so as to be folded against said trunk during storage and rotated therefrom for display.
