Description

[Detailed Description of the Invention] The present invention relates to an improvement in the support structure for the branches of a synthetic resin Christmas tree.

In recent years, many Christmas trees made of synthetic resin have come on the market, but buyers have to assemble them by inserting branches into the trunk, which requires time and effort to assemble and disassemble after use. It was inconvenient. For this reason, a foldable imitation Christmas tree was devised (Jikko Sho 58-11266).
(No.), the shaft attachment part is fragile and there are problems with strength, so it has not been commercialized at present. Moreover, in this case, since the pivoting part is small, even if one of the branches breaks, the entire tree must be replaced, which is uneconomical.

The present invention has been devised to overcome these drawbacks.

The embodiments will be described in detail below based on the drawings.

Reference numeral 1 is a support leg, and a support column 2 is erected in the center.
Reference numeral 3 denotes a trunk body having a central hole so that it can be inserted into the support column 2, and an arbitrary number of branch body holding parts 4 each having a U-shaped cross section are provided diagonally upward or downward on the outer circumferential side surface. . The base of the branch body holding part 4 is raised and a pin hole 5 is provided approximately at the center thereof.

Reference numeral 6 denotes a branch body whose base end 7 is expanded into a flat shape and has a pin hole 8 in its center.

Reference numeral 9 denotes a split pin, which is inserted and fixed into matching pin holes 5 and 8 of the branch body 6 and the branch body holding portion 4.

Since the present invention has the above-described configuration, the following actions and effects can be expected.

After inserting an arbitrary number of trunk bodies 3 into the pillars 2, the base ends 7 of branch bodies 6 of arbitrary shapes are clamped to the branch body holding parts 4 of the trunk body 3, and then pivoted with split pins 9 to form a box. Even when packing, the branch body 6 can be made smaller by folding around the split pin 9, and the purchaser can also remove the split pin 9 and replace it with a branch body 6 of any shape. Therefore, after use, the branches can be folded up and packed in a box without being disassembled, which not only makes it extremely easy to organize after use, but also makes it easy to replace the branches. . In addition, the branch body holding portion 4 has a cross section U
Since it is shaped like a letter, the branch body 6 fits into the pin, making the branch body 6 stable, and since no excessive force is applied to the pin, it is possible to prevent the branch body from wobbling. Furthermore, since the proximal end of the branch body, which is subjected to the most force and has the highest degree of damage, is expanded into a flat shape, the strength is increased and the commercial value is increased.

Note that if the upper part of the branch body holding part 4 is narrowed, the base end part 7 of the branch body 6 will be stabilized, and eccentricity of the pin 9 can be prevented. In addition, the main branch 6a of the branch body 6 is connected to the wire 1.
If the branches 6 are made of soft synthetic resin as bones, the branches 6 can be bent freely, so that the tree shape can be changed to the purchaser's preference.

As mentioned above, this invention allows the purchaser to pack the box without assembling or disassembling it, so it won't get in the way after Christmas, and the branches can be replaced freely, so it can be packaged to suit your taste. You can also make ivy trees.
