Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an improved Christmas tree, and its purpose is to make it easy to assemble and disassemble, to be convenient for transportation and storage, to prevent the branches from sagging due to the weight, and to prevent external damage. , it eliminates the drawbacks such as the egg shape collapsing due to sideways movement when attaching decorations, and can be assembled into beautiful branches, and it can also be used as a decorative electric light for the tree.
This is a great way to provide a Christmas tree in large quantities and at a low cost, with its branches not deformed even when other decorations are attached.

Conventionally, regarding Christmas trees, improvements have been made to the stand on which the tree is erected, in other words, the mounting structure of the tree's branch rods themselves has been improved, and more recently, tools, i.e., trunks, have been improved to insert the branches of the tree. A device was devised and proposed in which a device is formed into a tubular shape of metal 9 synthetic resin, into which the branches are inserted, and a device is inserted at appropriate intervals along with a spacing tube to maintain the spacing, and tree branches are inserted into this device. For example, the Actual Public Notice of 1939
Publication No. 7-7855, Publication No. 7856 of Showa 57, and Publication No. 12959 of Showa 57, etc. are the examples.

The above-mentioned publications allow insertion tubes for tree branches to be formed in a radial manner on the device to attach a large number of tree branches. The present invention is similar in that a large number of tree branches are inserted into one device, but the inserted tree is prevented from leaning downward or rotating due to its weight, and thus achieves the above-mentioned purpose. It is in.

Hereinafter, a more detailed explanation will be given with reference to the attached drawings.
Figure 1 is a front view of the entire Christmas tree, 8 is the entire Christmas tree (hereinafter simply referred to as the tree), B is the branch rod, with metal 2 in the center, synthetic resin tube 1, and spacer tubes 2 on the outer periphery. At the same time, the tree insertion tool B is sequentially inserted, and the tree 3 is inserted into the insertion tool B, and C is a support stand. This support C
The legs 4 are made of synthetic resin and are curved radially and inwardly into an arcuate shape, and when a large number of trees 3 are inserted into the insertion tool B, the insertion WA 4a of the support tube 1 on the upper surface is depressed downward by the weight of the whole. The structure is such that pressure is applied to the strut tube 1 to firmly clamp the strut tube 1 and prevent the strut tube 10 from rotating or being pulled out.

Next, as shown in FIGS. 2 to 5, the insertion device B for the tree 3 is formed using a mold using a synthetic resin material.
The insertion tool B shown in the figure has an insertion hole 6 that is inserted into the support pipe 1 in the center of the cylinder 5, and an insertion hole 7 of the tree 3 is inserted upward 7a with a fixed interval on the outer periphery of the insertion hole 6. is wide and narrow at the bottom, and an upwardly inclined surface 7b is formed approximately in the middle to make it easier to insert the branch rod 3a of the tree 30. In addition, a protruding piece 8 is provided at the upper end of the insertion hole 6 just above the insertion hole 7, as shown in FIG. This prevents the branch rod 3a of No. 3 from rotating or moving laterally inward. 9 is a protruding strip on the inner periphery of the insertion hole 6.

Next, the insertion tool Ba shown in FIGS. 4 and 5 is another embodiment of the insertion tool B, which has a fitting hole 6 formed in the center of the cylindrical body 5 and an upper opening of the fitting hole 6 of the cylindrical body 5. The connecting piece 10 expands outward in the
Following this, the insertion cylinder 11 of the branch rod 3a of the tree 3 is formed into one body by expanding the upper end outward. The lower end of this cylindrical body 11 is formed into a vertical cylinder 11a, and the center hole 12a is also formed to match this to form a dogleg-shaped center hole 12, 12&, and the center hole 12a of the vertical cylinder 11a is formed on the outside. When the tree 30 branch rod 3a is inserted by forming one side thicker and having a hole diameter equal to the diameter of the branch rod 3a of the tree 3, it will rotate and be removed, and the whole will turn upward and sag downward. prevent. Also, vertical cylinder 11. A protruding piece 13 is formed on the inner circumferential surface of a, and two receiving protrusions 14 are formed at intervals on the outer circumferential surface of the segment body 5. When the branch rod 3a of the tree 3 is inserted, the outer circumferential The protruding piece 13 of the vertical ft+ 11a enters between the receiving protruding pieces 14 to prevent horizontal vibration of the insertion f*11 (see Fig. 5), and the outer surface has reinforcing protruding pieces extending over both cylinders. 15 is formed and reinforced to prevent deformation of the insertion tube.

Since the present invention is constructed as described above, the insertion tool for inserting the tree is inserted into the spacer tube at appropriate intervals depending on the length of the support tube, and especially when a tree made of synthetic resin is inserted, the support base is inserted into the support tube. Because the weight of the upper insertion tube bends downward, the outer periphery of the support tube receives pressure and is strongly clamped, preventing it from being pulled out or swaying laterally.
In addition, one side of the insertion hole of the insertion device has an upwardly sloping surface, and the other side is entirely sloped, making it easy to insert.The insertion hole is also curved in a dogleg shape, so it can be inserted naturally after insertion. It is difficult to remove and does not move inward or outward, so the tree can be maintained in its inserted state and will not be deformed due to changing the shape of the tree, making a good-looking Christmas tree.Furthermore, it is easy to disassemble and assemble. It has many advantages, including great convenience in terms of disassembly, storage, and transportation.
