Description

Technical Field

[0001] The invention belongs to the technical field of artificial Christmas trees, and in particular relates to a simulated Christmas tree and a preparation process thereof. Background Art

[0002] Christmas trees, as a must-have Christmas decoration in Europe and the United States, are often placed in homes, courtyards, commercial streets and other places before Christmas.

[0003] In recent years, artificial Christmas trees have become the mainstream in the market, replacing real ones made from coniferous trees. Artificial Christmas trees are widely popular among consumers because they meet environmental requirements and can be reused.

[0004] However, the degree of simulation of current artificial Christmas trees is limited, especially at the trunk and branch ends. To improve production efficiency, existing products use thin wire wrapped around the outside of the rod to simulate the trunk's shape. While this molding efficiency is high, the appearance differs significantly from that of a real trunk and branches. To further enhance the similarity, other methods include gluing particles, spraying paint, or attaching bionic bark to the outer surface of the trunk material to achieve an appearance similar to that of a real tree. However, the actual simulation is poor, and the long drying time for the glue and paint limits production capacity. Summary of the Invention

[0005] In order to address the deficiencies of the prior art, the present invention provides an artificial Christmas tree and a preparation process. By providing a cutting protrusion and a cutting cavity, the first fixing portion of the first branch is inserted into the gap, and then the first fixing portion is bonded and fixed between the first rubber and the top trunk by fixing glue, thereby achieving a more realistic appearance and better quality and texture while ensuring a simple and stable structure and streamlined overall production process.

[0006] The technical effects to be achieved by the present invention are achieved through the following technical aspects:

[0019] The tree branch support has an open umbrella-like structure and includes an umbrella support with a supporting space; and

[0020] The second branch comprises a second branch rod and needles extending outward from the second branch rod, wherein the second branch rod has a second fixing portion at one end away from the needles;

[0021] The branch support is fixed to the middle of the second kit; the branch support includes a rotating shaft, which passes through the umbrella holder and the second fixing part to rotate the second branch in the supporting space.

[0022] In some implementations, in the vertical direction, a first plug-in is provided at the bottom of the top kit, and a second plug-in matching the first plug-in is provided at the top of the second kit. The first plug-in is plugged into the second plug-in to make the top kit and the second kit plugged and fixed.

[0023] In some implementations, a cross-section of the first plug-in and the second plug-in in the plugging direction is polygonal or circular.

[0024] In some implementations, the second branch is further provided with a fourth rubber sheet, and the fourth rubber sheet is provided between the second fixing portion and the needle closest to the second fixing portion.

[0025] In some implementations, one end of the fourth rubber sheet close to the second fixing portion is located in the supporting space.

[0026] In a second aspect, the present invention provides a preparation process for making the above-mentioned artificial Christmas tree, including a method for preparing the top kit;

[0041] In summary, the present invention has at least the following benefits:

[0042] 1. The artificial Christmas tree provided by the present invention secures the first branch by inserting the first fixing portion into the socket and into the gap. Fixing glue then fills the cutting cavity and part of the gap. When solidified, the first fixing glue adheres between the first rubber sheet and the top trunk, also securing the first rubber sheet and the top trunk. Its simple and stable structure, combined with prefabricated first branches, facilitates streamlined production.

[0043] 2. The artificial Christmas tree provided by the present invention simulates tree bark through the first rubber sheet, and because the insertion hole is inclined toward the top, after the first fixing part is inserted into the insertion hole, the first branch is fixed in a state of being inclined to the top trunk and extending toward the top; secondly, the cutting protrusion is set on the periphery of the first rubber sheet, and the first branch is inserted into the cutting protrusion. After the fixing glue is filled, the appearance of the first fixing part is closer to the growth form of real tree branches in reality. Compared with existing artificial Christmas trees, the appearance is more realistic and the quality texture is better.

[0044] 3. The preparation process provided by the present invention uses a cutting tool to randomly cut out incisions and turn outward to form insertion holes and insertion cavities, thereby improving the molding quality and making the production of the artificial Christmas tree more efficient.

[0065] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0066] Example 1:

[0067] See also Figure 1-Figure 2 The present invention provides an artificial Christmas tree 100 that imitates a real pine or cypress tree. The artificial Christmas tree 100 includes a top assembly 1 disposed on the top.

[0068] Specifically, the top assembly 1 comprises a top trunk 11, a first rubber cover 12, and first branches 14. The top trunk 11 is a vertically arranged rod-shaped structure, providing support and orientation for the entire top assembly 1. The rod can be solid or tubular, and can be made of wood, plastic, or metal, depending on the actual situation. In this embodiment, the top trunk 11 is a metal tubular member to achieve both reduced weight for transportation and a high load-bearing capacity.

[0069] The first rubber sheet 12 elastically wraps around the outside of the top trunk 11. Its outer surface can be patterned to mimic the grain of a coniferous tree trunk, while a gap 13 is formed between its inner surface and the top trunk 11. The outer periphery of the first rubber sheet 12 is provided with a protruding insert 121 and a cavity 122 disposed within the protruding insert 121. To achieve a realistic design, the protruding insert is typically integrally molded into the first rubber sheet 12.

[0070] The first branch 14 includes a first branch rod 141 and needles 143 extending outward from the first branch rod 141. The needles 143 are integrally formed by an injection molding mold. The first branch 14 can be formed by injection molding the needles 143 integrally at one end of the first branch 14, or each needle 143 can be completed independently and then fixed to the first branch 14 in an outwardly extending form by bonding. In order to imitate the growth of branches, the needles 143 generally cover most of the first branch 14 and extend obliquely in the same direction. On the side opposite to the extension direction of the needles 143, the first branch rod 141 is provided with a first fixing portion 142.

[0071] More specifically, the top of the cutting protrusion 121 facing the vertical direction X is provided with an inclined socket 123, the socket 123, the cutting cavity 122 and the gap 13 are connected, and the first fixing part 142 enters the gap 13 through the socket 123 to achieve basic fixation of the first branch 14. The first fixing part 142 is often made of a soft material that can be shaped. When the first fixing part 142 is inserted into the gap 13, it bends and deforms along the direction of the top trunk 11. The top kit 1 includes a fixing glue 15, which bonds and fixes the first fixing part 142 between the first rubber 12 and the top trunk 11. At the same time, the fixing glue 15 also fixes and bonds the first rubber 12 and the top trunk 11, thereby strengthening the firmness of the connection between the two.

[0072] In practical applications, the first rubber cover 12 can be produced using an injection molding process. Both the first branches 14 and the first rubber cover 12 can be fabricated before the top assembly 1 is assembled, meeting the modular and streamlined production line requirements. This avoids the need for multiple intervening processes that could impact overall production efficiency. Furthermore, the top assembly 1 of the artificial Christmas tree 100 exhibits a simple structure, stable connections, and ease of assembly.

[0073] In terms of texture, the first rubber sheet 12 can achieve a visual and tactile effect similar to tree bark when it is formed, and the gap 13 can be filled with glue or other materials, and then the outer side of the first rubber sheet 12 can be shaped to enhance the overall tactile feel of the tree trunk. Of course, if the gap 13 is not filled for weight reasons, the appearance can also achieve a near-realistic effect. The socket 123 is tilted toward the top. After the first fixing portion 142 is inserted into the socket 123, the first branch 14 is fixed in a state of tilting toward the top of the top trunk 11. The cutting protrusion 121 is set on the periphery of the first rubber sheet 12, and the first fixing portion 142 is wrapped by the cutting protrusion 121. The appearance is closer to the growth form of the branches of coniferous trees in reality. The first fixing portion 142 grows out from the side like a "trunk". Compared with existing artificial Christmas trees, under the premise of simple and stable structure and mass production, the appearance is more realistic and the quality texture is better.

[0074] In some embodiments, the protruding insert 121 need not be formed during the production of the first rubber sheet 12. Instead, it is formed during the assembly process by cutting and everting the first rubber sheet 12 at an angle toward the top trunk 11, with the top portion thereof facing the vertical direction X. Due to the randomness inherent in the manual cutting and everting process, the "growth state" of the top assembly 1 of each assembled artificial Christmas tree 100 varies, more closely resembling a naturally grown Christmas tree. Furthermore, the protruding insert 121 formed by cutting and everting, in addition to being cost-effective, also features a tighter connection between the first fixing portion 142 and the protruding insert 121 due to the certain elasticity of the first rubber sheet 12, more closely resembling the growth pattern of a branch, thereby enhancing the simulated texture.

[0075] In a further embodiment, the first branch 14 includes a second rubber sheet 144, which is wrapped around and fixed to the periphery of the first fixing portion 142. Figure 1-Figure 2 Based on Figure 3 The second rubber sheet 144 is similar to the first rubber sheet 12, imitating the outer texture of the branch. After being inserted into the first fixing portion 142, it is bonded with glue or a heat-shrinkable material and fixed to the outside of the first fixing portion 142. To ensure a continuous texture and a realistic visual effect, one end of the second rubber sheet 144 is placed in the insertion cavity 122 and abuts the inner wall of the insertion protrusion 121.

[0076] In other embodiments, to further enhance the tree trunk's simulated texture and effect, the first rubber sheet 12 is formed from a soft, elastic material such as rubber, plastic, or silicone. This allows for a visual and tactile appearance closer to that of a real coniferous tree trunk. Furthermore, to simulate the growth of the tree trunk, the outer diameter of the first rubber sheet 12 decreases gradually from bottom to top in the vertical direction X.

[0077] Furthermore, the outer surface of the first rubber sheet 12 has a simulated bark-like texture. In order to make the first rubber sheet 12 feel firmer, a filling rubber 131 and a filling piece 132 are provided in the gap 13, or only one of the filling rubber 131 and the filling piece 132 is provided. In this embodiment, Figure 4 As shown, the filling piece 132 and the filling glue 131 are both provided so that the first rubber skin 12 has a moderate touch feeling of softness and hardness. The filling piece 132 can be a plastic rod or a rubber rod, etc., and the filling glue 131 feels soft after solidification, close to the texture of a tree trunk.

[0078] In some embodiments, because the overall height of the desired Christmas tree is relatively low, only the top member 1 is sufficient. In this case, the bottom of the top member 1 is left sufficiently long to be inserted into a fixed tree pot or bracket. The first branches 14 or needles 143 can also be glued and fixed to the top of the top member 1 to cover the exposed portion of the top trunk 11.

[0079] In summary, the artificial Christmas tree provided by the present invention secures the first branch by inserting the first fixing portion into the insertion hole and into the gap. Fixing glue then fills the cutting cavity and part of the gap. When solidified, the first fixing glue adheres between the first rubber sheet and the top trunk, also securing the first rubber sheet and the top trunk. Its simple and stable structure, combined with prefabricated first branches, facilitates streamlined production.

[0080] Secondly, the first rubber sheet simulates the bark of the tree, and since the socket is tilted toward the top, after the first fixing part is inserted into the socket, the first branch is fixed in a state of being tilted to the top trunk and extending toward the top; secondly, the cutting protrusion is set on the periphery of the first rubber sheet, and the first branch is inserted into the cutting protrusion. After the fixing glue is filled, the appearance of the first fixing part is closer to the growth form of real tree branches in reality. Compared with the existing artificial Christmas trees, the appearance is more realistic and the quality texture is better.

[0081] Example 2:

[0082] This embodiment is a further structural expansion based on the artificial Christmas tree 100 described in Example 1. Figures 1-4 Refer to the basis Figure 5-Figure 8. What is different between this embodiment and Example 1 is that the artificial Christmas tree 100 described in this embodiment also includes a second kit 2 that is plugged into the top kit 1. The second kit 2 includes a second trunk 21, a third rubber 22, a branch support 23 and a second branch 24. The second trunk 21 is the same as the top trunk 11, and both are vertically arranged in a rod-shaped structure. The second trunk 21 is plugged and fixed to the bottom of the top kit 1 at the top in the vertical direction X. The third rubber 22 is similar to the first rubber 12 in function and style, and is sleeved and fixed to the outer surface of the second trunk 21. In this embodiment, the third rubber 22 is directly attached and fixed to the outer surface of the second trunk 21, and no gap 13 or similar structure is provided to improve assembly efficiency.

[0083] The branch support 23 has an open umbrella-like structure, comprising a main body 234 and a support 231 extending outward from the main body 234. The support 231 defines a support space 232. The second branch 24 is similar in structure to the first branch 14, comprising a second branch 241 and needles 143 extending outward from the second branch 241. A second fixing portion 242 is defined at the end of the second branch 241 away from the needles 143.

[0084] Specifically, the branch support 23 is fixed to the middle of the second set 2. In this embodiment, the main body 234 of the branch support 23 is a tubular structure, which passes through and is tightly attached to the outside of the third rubber 22. The branch support 23 is fixed to the middle of the second set 2 by pressing or nailing the main body 234. In other embodiments, such as Figure 9 As shown, multiple sections of second trunks 21 and third rubber sheets 22 are provided in the same second kit 2 , and the branch supports 23 are inserted between the two second trunks 21 in a nested manner.

[0085] Continue reading Figure 5-Figure 8 The branch support 23 includes a rotating shaft 233, which passes through the umbrella support 231 and the second fixing portion 242, and rotates the second branch 24 to be set in the supporting space 232. In this embodiment, the second fixing portion 242 is significantly different from the first fixing portion 142. It is bent and surrounded to form a hole, and the rotating shaft 233 passes through the hole to achieve the rotational fixation of the second fixing portion 242. Similarly, the umbrella support 231 also has a corresponding hole for the rotating shaft 233 to pass through, so as to achieve the above-mentioned connection effect. The rotating shaft 233 can be a standard component such as a rivet, screw, stud, etc., and in this embodiment, it is a rivet. The second fixing portion 242 can also be provided with a hole by perforation.

[0086] The umbrella holder 231 and the main body 234 have a certain angle, so that the second branch 24 has a certain inclination angle with the second trunk 21 in the supporting space 232, simulating the growth pattern of branches and needles.

[0087] For taller artificial Christmas trees, using only the top kit 1 to create the entire tree, while realistic, increases the manufacturing difficulty as the height increases. Therefore, the second kit 2 addresses this issue. By pre-installing the second branches 24 on the branch supports 23 and then securing the branch supports 23 to the outer surface of the third rubber sheet 22, the overall manufacturing process is significantly simplified and production efficiency is improved. Alternatively, the branch supports 23 can be installed in the middle of the second kit 2 first, followed by the second branches 24. The specific order of installation depends on the actual situation.

[0088] By adding more needles 143 and increasing the length of the second branch 241, the second branches 24 can meet the shaping requirements of the Christmas tree's lower end. Furthermore, the second fixing portion 242 is rotatably mounted on the umbrella holder 231. When packaging the product or storing it for customer needs, the second branches 24 can be flipped toward the second trunk 21 to reduce their size and be packaged together with the top assembly 1. In this embodiment, because the support space 232 is tilted upward, gravity can disperse the second branches 24 without the need for a supporting mechanism, making operation simple and easy.

[0089] In some embodiments, in the vertical direction X, a first plug-in 16 is provided at the bottom of the top assembly 1, and a second plug-in 25 is provided at the top of the second assembly 2, which matches the first plug-in 16. The first plug-in 16 and the second plug-in 25 are plugged together to secure the top assembly 1 and the second assembly 2. The first plug-in 16 can be a convex or concave member, while the second assembly 2 is configured as a concave or convex member that matches the first plug-in 16. In this embodiment, the first plug-in 16 is a convex member that is adhesively fixed to the bottom of the top assembly 1, and the second plug-in 25 is inserted into the bottom inner side of the second trunk 21 to achieve better concealment. The plug-in connection between the first plug-in 16 and the second plug-in 25 simplifies the splicing and fixing process of the artificial Christmas tree 100.

[0090] Specifically, the cross section of the first plug-in 16 and the second plug-in 25 in the plugging direction is polygonal, such as a quadrilateral, a hexagon, a trapezoid, etc., or the cross section is circular.

[0091] In other embodiments, in order to improve the degree of simulation of the second set 2, the second branch 24 is further provided with a fourth rubber 243, and the fourth rubber 243 is sleeved between the second fixing portion 242 and the needle 143 closest to the second fixing portion 242. As a result, the entire transition from the second trunk 21 to the second branch 241 is more natural. At the same time, since the fourth rubber 243 is the same as the second rubber 144, it does not require additional equipment, and while ensuring the simulation effect, it does not increase the production line investment. More specifically, the end of the fourth rubber 243 close to the second fixing portion 242 is located in the supporting space 232. This creates a continuity between the third rubber 22 and the fourth rubber 243, reducing the abruptness of the branch support 23.

[0092] With the addition of the second kit, the artificial Christmas tree can be made taller and larger without sacrificing the simulation effect, meeting the modularization and production line requirements of mass production and limiting the cost increase. It also facilitates packaging and storage, reducing transportation costs.

[0093] Of course, for a larger artificial Christmas tree 100, multiple second sets 2 can also be added for plug-in connection.

[0094] Example 3:

[0095] This embodiment provides a preparation process for making the artificial Christmas tree 100 in Example 2. The preparation process includes a preparation method of the top kit 1.

[0096] It should be noted that before assembling the top kit 1, the first rubber sheet 12 and the first branch 14 need to be prepared first. The specific molding method of the first rubber sheet 12 and the first branch 14 has been described in Example 1 and will not be repeated here.

[0097] Please Figures 1-9 Based on Figure 10-11 , the manufacturing method of the top kit 1 is as follows:

[0098] S1: Cut the top trunk 11 to the required length, put the first rubber sheet 12 on the outside of the top trunk 11, and fix the two at the top of the vertical direction X. Since the diameter of the top is small, it can be achieved by gluing or plastic heat shrink wrapping, such as Figure 10 As shown in a.

[0099] S2: Use the cutting tool 3 to cut the first rubber sheet 12 from the top to the bottom in the vertical direction X, obliquely toward the top trunk 11, until the cutting tool 3 enters the gap 13, forming an incision 124, as shown in FIG. Figure 10 As shown in b.

[0100] S3: After the cutting blade 3 forms the incision 124, do not remove the cutting blade 3 immediately. Instead, apply lateral force to the cutting blade 3 to turn the incision 124 outward, forming the protruding insert 121, and simultaneously forming the insertion hole 123 and the insertion cavity 122. At this point, the first rubber 12 at the upper end of the insertion cavity 122 can be pressed downward to create a larger insertion space.

[0101] S4: As Figure 10 As shown in FIG. 3 c , the first fixing portion 142 of the first branch 14 is inserted into the insertion hole 123 and enters the gap 13 . After the first fixing portion 142 abuts against the top trunk 11 , it bends and enters the gap 13 .

[0102] S5: See Figure 10d. Use a hot melt glue gun or glue injection tube to inject an appropriate amount of fixing glue 15 into the position of the insertion hole 123. After the fixing glue 15 solidifies, the first rubber 12, the first fixing part 142 and the top trunk 11 are bonded and fixed to each other.

[0103] S6: Repeat steps S2-S5 to complete the installation of other first branches 14 of the top kit 1.

[0104] The top kit completed through the above steps has improved molding quality, and each step is simple and easy to operate. Compared with existing mass-produced artificial Christmas trees, its production efficiency is higher.

[0105] In this embodiment, the preparation process also includes a preparation method for making any of the second kits 2 of Example 2.

[0106] Among them, in the vertical direction X, a first plug-in 16 is provided at the bottom of the top kit 1, and a second plug-in 25 matching the first plug-in 16 is provided at the top of the second kit 2. The first plug-in 16 and the second plug-in 25 are plugged in and matched, so that the top kit 1 and the second kit 2 are plugged and fixed.

[0107] It should be noted that the second trunk 21, the third rubber 22, the branch support 23 and the second branch 24 are the same as the first trunk and the first branch 14, and all need to be prepared in advance and ready for assembly. The preparation process of the artificial Christmas tree 100 specifically includes the following additional preparation methods:

[0108] S7: The first insert 16 is fixed to the bottom of the top cover 1. The fixing of the two can be achieved by adhesive or other methods. Of course, if the gap 13 needs to be filled, it needs to be filled into the gap 13 through the bottom of the top cover 1 before the first insert 16 is fixed.

[0109] S8: The third rubber sheet 22 is fitted and fixed to the outer surface of the second trunk 21 by adhesive or heat shrinking. The second plug-in 25 is fixed to the top of the second trunk 21 in a similar manner to the first plug-in 16.

[0110] S9: As Figure 11 As shown in FIG. 1 a , the second fixing portion 242 is disposed in the supporting space 232 , the shaft 233 passes through the umbrella holder 231 and the second fixing portion 242 , and both ends of the shaft 233 are clamped on the outside of the umbrella holder 231 .

[0111] S10: Repeat step S9 until Figure 11 As shown in b, all the supporting spaces 232 are installed with second branches 24.

[0112] S11; The branch bracket 23 having the second branch 24 is fixed to the middle of the second set 2, such as Figure 11 As shown in c.

[0113] S12: Figure 11 As shown in FIG. 5 , the first plug-in 16 and the second plug-in 25 are plugged and fixed together, completing the installation of the top kit 1 and the second kit 2.

[0114] In actual operation, steps S9-S10 can be performed in parallel with the entire process flow to improve production efficiency. If production volume is low or production capacity is limited, the branch support 23 can be pre-fixed to the center of the second assembly 2 before executing steps S9-S10 and omitting step S11. Due to the complexity of actual production conditions, the specific process flow may be adjusted. However, the overall assembly logic remains essentially the same and will not be repeated here.

[0115] In summary, the preparation process provided in this embodiment uses a cutting tool to randomly cut out incisions and turn them outward to form insertion holes and insertion cavities, which improves the molding quality and makes the production of the artificial Christmas tree more efficient.

[0116] The above description is merely an example and illustration of the structure of the present invention. Although the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the scope of the present invention, and such obvious alternatives are all within the scope of protection of the present invention.
