Christmas tree with storage table

Abstract

The invention relates to the technical field of simulated Christmas trees, in particular to a Christmas tree with a storage table. According to the Christmas tree with the storage table, the technical problem that in the prior art, a Christmas tree with a storage structure is prone to toppling is solved. A Christmas tree with a storage table comprises a base. The tree trunk is arranged on the base; and a storage assembly. When the weight of objects in the storage rack is not uniform, and the acting force borne by the tree trunk is not balanced, the heavy storage rack can overcome the elastic acting force of the first elastic piece and move in the direction close to the rotating shaft. Meanwhile, through the action of the linkage assembly, the other storage rack can be pushed to move in the direction away from the rotating shaft. By means of the displacement mechanism, the length of the force arm between the heavy storage rack and the rotating shaft is smaller than the length of the force arm between the other storage rack and the rotating shaft, so that balance of a tree trunk is kept or stress non-uniformity is reduced, and the Christmas tree is effectively prevented from toppling over.

Description

Technical Field

[0001] This invention relates to the field of simulated Christmas tree technology, and more particularly to a Christmas tree with a shelf. Background Technology

[0002] Artificial Christmas trees are a type of decorative item, usually used to create a festive atmosphere during holidays.

[0003] Artificial Christmas trees typically consist of a trunk and a base. The trunk is set on the base, and decorations such as branches and leaves are installed on the trunk. In practice, artificial Christmas trees are usually only used during holidays. To increase the functionality of artificial Christmas trees, existing technology has developed a type with a storage compartment. Users can place items in the compartment, giving the tree both decorative and storage functions. While this type of artificial Christmas tree has multiple functions, the presence of the storage compartment makes it prone to tipping over when the weight of the items inside is uneven. In particular, when the relative force is uneven, it usually tipes over directly without prompting the user to adjust the placement of items in the compartment.

[0004] Therefore, existing Christmas trees with storage structures have the technical problem of being prone to tipping over. Summary of the Invention

[0005] The present invention provides a Christmas tree with a shelf, which solves the technical problem that Christmas trees with shelf structures in the prior art are prone to tipping over.

[0006] Some implementation schemes for solving the above-mentioned technical problems include:

[0007] A Christmas tree with a stand, including a base;

[0008] A tree trunk, which is disposed on the base;

[0009] The tree trunk includes at least two storage components, which are evenly distributed vertically along the trunk and decorate it to form the trunk of a Christmas tree.

[0010] Each of the storage components includes a storage rack symmetrically arranged on the tree trunk. The storage rack is slidably connected to the tree trunk in a vertical direction. A first elastic element supporting the storage rack is provided between the storage rack and the tree trunk. A linkage component that keeps the tree trunk balanced is provided between two oppositely arranged storage racks.

[0011] When two oppositely positioned shelves exert different forces on the tree trunk due to their different weights, causing an imbalance in the forces acting on the tree trunk, the tree trunk tilts around the axis of rotation. The heavier shelf overcomes the elastic force of the first elastic element and displaces closer to the axis of rotation. Simultaneously, the linkage component pushes the other shelf to displace further away from the axis of rotation, making the lever arm length between the heavier shelf and the axis of rotation smaller than that between the other shelf and the axis of rotation. Furthermore, by making the lever arm lengths between the two oppositely positioned shelves and the axis of rotation different, the tree trunk is kept in balance or the unevenness of the forces is reduced.

[0012] Preferably, the base is slidably connected to a counterweight, and the tree trunk is provided with a push rod that pushes the counterweight to move. When the tree trunk tilts around the rotation axis, the push rod pushes the counterweight to move in the opposite direction to the tilting direction of the tree trunk, so as to prevent or slow down the tree trunk from falling over.

[0013] Preferably, the tree trunk is a hollow structure, and the tree trunk is provided with a groove that runs through the side wall of the tree trunk. The linkage component includes a slider disposed on the shelf and cooperating with the groove. The linkage component also includes a rack disposed on the slider. The rack is located inside the tree trunk. The linkage component also includes a gear rotatably connected to the tree trunk. The gear is located between the racks of two oppositely disposed shelves.

[0014] Preferably, the rack has an arc-shaped cross-section, and the side of the rack closest to the inner wall of the tree trunk contacts the inner wall of the tree trunk, while the gear simultaneously meshes with the racks of the two oppositely arranged shelves.

[0015] Preferably, the gear is mounted on the tree trunk via a shaft, and a rolling bearing is provided between the gear and the shaft.

[0016] Preferably, the shelf is provided with a storage slot, and the storage slot is provided with a partition that divides the storage slot into an inner area and an outer area. The partition and the shelf are an integral structure.

[0017] Preferably, the first elastic element is a spring, one end of the first elastic element is fixed to the slider, and the other end of the first elastic element is fixed to the bottom wall of the groove.

[0018] Preferably, the shelf includes a guide wall, which is an integral part of the shelf, and the guide wall cooperates with the rack to guide the shelf.

[0019] Preferably, the tree trunk is rotatably connected to the base via a connector. The connector includes an upper half fixed to the tree trunk and a lower half fixed to the base. The upper half and the lower half are rotatably connected. A second elastic element is provided between the upper half and the lower half to keep the upper half and the lower half in a coaxial state. The upper half is provided with a limiting shoulder that limits the rotation angle of the upper half relative to the lower half. The limiting shoulder limits the rotation angle of the upper half relative to the lower half by interfering with the lower half.

[0020] Preferably, the lower half is provided with a through hole, the push rod extends out of the through hole and corresponds to the counterweight, the counterweight is provided with a sliding groove, and the base is provided with a slider that cooperates with the sliding groove.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] When the weight of items within the shelves is uneven, causing an imbalance in the forces acting on the tree trunk, the heavier shelf will overcome the elastic force of the first elastic element and shift towards the axis of rotation. Simultaneously, through the linkage mechanism, the other shelf will be pushed away from the axis of rotation. This displacement mechanism ensures that the lever arm between the heavier shelf and the axis of rotation is less than that between the other shelf and the axis of rotation, thus maintaining the balance of the tree trunk or reducing the unevenness of force, effectively preventing the Christmas tree from tipping over.

[0023] The varying height of the shelves serves as a visual cue, drawing the user's attention to uneven weight distribution among items. This prompts the user to adjust the placement of items within the shelves to maintain the Christmas tree's stability and aesthetic appeal. This design not only preserves the Christmas tree's decorative function but also, through the addition of storage components, gives it the ability to hold items.

[0024] During the holidays, this artificial Christmas tree can both enhance the festive atmosphere and serve as a small shelf, increasing its practicality and versatility. The design of the first elastic element and linkage components enhances the structural stability of the Christmas tree, allowing it to remain balanced while bearing items of varying weights.

[0037] The specific embodiments shown below are intended to describe various configurations of the subject matter of the invention and are not intended to represent the only configuration in which the subject matter of the invention can be practiced. The specific embodiments include particular details intended to provide a thorough understanding of the subject matter of the invention. However, it will be clear and apparent to those skilled in the art that the subject matter of the invention is not limited to the specific details shown herein and can be practiced without these specific details.

[0038] Understandably, in this document, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another, and are not intended to expressly or imply any actual relationship or order between these entities or operations.

[0039] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0040] Reference Figures 1 to 7 As shown, a Christmas tree with a stand includes a base 1;

[0041] Tree trunk 2, which is disposed on the base 1;

[0042] The tree trunk 2 is decorated with a storage component 3, which consists of at least two components and is evenly distributed vertically. The storage component 3 decorates the tree trunk 2 to form the trunk of a Christmas tree.

[0043] Each of the storage components 3 includes a storage rack 31 symmetrically arranged on the tree trunk 2. The storage rack 31 is slidably connected to the tree trunk 2 in the vertical direction. A first elastic element 311 supporting the storage rack 31 is provided between the storage rack 31 and the tree trunk 2. A linkage component 32 that keeps the tree trunk 2 balanced is provided between two oppositely arranged storage racks 31.

[0044] If two oppositely positioned shelves 31 exert different forces on the tree trunk 2 due to their different weights, causing an imbalance in the forces acting on the tree trunk 2, the tree trunk 2 will tilt around the rotation axis. The heavier shelf 31 will overcome the elastic force of the first elastic element 311 and move closer to the rotation axis. At the same time, the linkage assembly 32 will push the other shelf 31 to move away from the rotation axis, so that the lever arm length between the heavier shelf 31 and the rotation axis is less than the lever arm length between the other shelf 31 and the rotation axis. Furthermore, by making the lever arm lengths between the two oppositely positioned shelves 31 and the rotation axis different, the tree trunk 2 is kept in balance or the unevenness of the force is reduced.

[0045] Reference Figure 2 As shown, it is understandable that when an item is placed in one of the shelves 31, although the tree trunk 2 is subjected to uneven force, it will not tip over due to the support of the base 1; it will only have a tendency to tip over. That is, although the tree trunk 2 will not tip over immediately after the force becomes uneven, it already has a tendency to tip over. When an item is placed on the shelf 31 that already contains an item, it may cause the tree trunk 2 to tip over directly.

[0046] Therefore, by sliding the shelf 31 to the tree trunk 2, the shelf 31, on which items are placed, moves downward under the action of gravity, overcoming the elastic force of the first elastic element 311. On the one hand, the height difference between the two oppositely positioned shelves 31 prompts the user to place items on other shelves 31, preventing the tree trunk 2 from tipping over due to items being concentrated on one shelf 31. On the other hand, when the shelf 31 moves downward, the linkage component 32 causes the other shelf 31 opposite to it to move upward. The shelf 31 that moves upward under the action of gravity acts as a counterweight, preventing the tree trunk 2 from tipping over.

[0047] Because the two shelves 31 are set at different heights, the heavier shelf 31 has a shorter lever arm to the rotation axis, and thus exerts a smaller rotational force on the tree trunk 2. Conversely, the heavier shelf 31 has a longer lever arm to the rotation axis, and thus exerts a greater rotational force on the tree trunk 2. This causes the rotational force exerted by the heavier shelf 31 on the tree trunk 2 to cancel out or reduce the force exerted by the lighter shelf 31 on the branches, thereby preventing the tree trunk 2 from tipping over.

[0048] In practice, due to the linkage component 32, the tree trunk 2 will not fall directly. Instead, it will first issue a warning through the height difference between the two shelves 31. The tree trunk 2 will only fall when the items on the heavier shelf 31 cause it to tilt. This effectively prevents the tree trunk 2 from falling and improves the stability of the Christmas tree.

[0049] In some embodiments, the base 1 is slidably connected to a counterweight 11, and the tree trunk 2 is provided with a push rod 21 that pushes the counterweight 11 to move. When the tree trunk 2 tilts around the rotation axis, the push rod 21 pushes the counterweight 11 to move in the opposite direction to the tilting direction of the tree trunk 2, so as to prevent or slow down the tree trunk 2 from tipping over.

[0050] Understandably, Christmas trees typically tip over quickly, and the trunk 2 and items placed on the shelf 31 are easily damaged. Therefore, by setting up a counterweight 11 and a push rod 21, when the trunk 2 tilts relative to the base 1, the counterweight 11 is pushed to move, increasing the lever arm between the counterweight 11 and the rotation axis. This allows the counterweight 11 to apply a greater force, preventing the Christmas tree from tilting or slowing its tipping speed, thereby further optimizing the stability of the Christmas tree.

[0051] In some embodiments, the number of counterweights 11 is not limited and can be configured reasonably as needed.

[0052] Reference Figures 1 to 7As shown, in some embodiments, the tree trunk 2 is a hollow structure, and the tree trunk 2 is provided with a groove 22 that penetrates the side wall of the tree trunk 2. The linkage component 32 includes a slider 312 disposed on the shelf 31 and cooperating with the groove 22. The linkage component 32 also includes a rack 313 disposed on the slider 312. The rack 313 is located inside the tree trunk 2. The linkage component 32 also includes a gear 321 rotatably connected to the tree trunk 2. The gear 321 is located between the racks 313 of the two shelves 31 disposed opposite to each other.

[0053] Understandably, the rack 313, slider 312, and shelf 31 can be an integrated structure to improve the stability of the Christmas tree. The trunk 2 can be made of a split structure, with the various parts of the Christmas tree fixed together by welding to facilitate the assembly of the trunk 2 and the shelf 31.

[0054] In some embodiments, the rack 313 has an arc-shaped cross-section, and the side of the rack 313 closest to the inner wall of the tree trunk 2 contacts the inner wall of the tree trunk 2. The gear 321 simultaneously meshes with the racks 313 of the two oppositely arranged shelves 31.

[0055] That is, the rack 313 is in surface contact with the inner wall of the tree trunk 2, and the rack 313 has a guiding function for the shelf 31.

[0056] In some embodiments, the gear 321 is mounted on the tree trunk 2 via a shaft 322, and a rolling bearing is provided between the gear 321 and the shaft 322. The shaft 322 may also be mounted on the tree trunk 2 in other ways.

[0057] In some embodiments, the shelf 31 is provided with a storage slot 314, and a partition 315 is provided in the storage slot 314 to divide the storage slot 314 into an inner area and an outer area. The partition 315 and the shelf 31 are an integral structure.

[0058] Items should generally be placed in the inner area, closer to the tree trunk 2, to reduce the force exerted on the tree trunk 2.

[0059] In some embodiments, the shelf 31 may be provided with decorative features, such as artificial leaves, light strips, etc., to make the Christmas tree more beautiful.

[0060] In some embodiments, the first elastic element 311 is a spring, one end of the first elastic element 311 is fixed to the slider 312, and the other end of the first elastic element 311 is fixed to the bottom wall of the groove 22.

[0061] The first elastic element 311 can be fixed by welding.

[0062] In some embodiments, the shelf 31 includes a guide wall 316, which is an integral structure with the shelf 31. The guide wall 316 cooperates with the rack 313 to guide the shelf 31.

[0063] The guide wall 316 and the rack 313 are both used to guide the shelf 31, which improves the displacement accuracy of the shelf 31.

[0064] Reference Figures 1 to 7 As shown, in some embodiments, the tree trunk 2 is rotatably connected to the base 1 via a connector 23. The connector 23 includes an upper half 231 fixed to the tree trunk 2 and a lower half 232 fixed to the base 1. The upper half 231 and the lower half 232 are rotatably connected. A second elastic element 233 is provided between the upper half 231 and the lower half 232 to keep the upper half 231 and the lower half 232 in a coaxial state. The upper half 231 is provided with a limiting shoulder 2311 that limits the rotation angle of the upper half 231 relative to the lower half 232. The limiting shoulder 2311 limits the rotation angle of the upper half 231 relative to the lower half 232 by interfering with the lower half 232.

[0065] The upper part 231 may include a spherical part, and the lower part 232 may include a spherical groove. The spherical part and the spherical groove are engaged. The depth of the spherical groove is greater than the radius of the spherical groove to prevent the spherical part from separating from the spherical groove.

[0066] Typically, the rotation angle of the upper half 231 relative to the lower half 232 is very small; it is sufficient to tilt the tree trunk 2 to provide a visual indication. Therefore, the second elastic element 233 should have a relatively large elastic force to keep the tree trunk 2 in a vertical position.

[0067] In some embodiments, the lower half 232 is provided with a through hole, the push rod 21 extends out of the through hole and corresponds to the counterweight 11, the counterweight 11 is provided with a sliding groove 22, and the base 1 is provided with a slider 312 that cooperates with the sliding groove 22.

[0068] In some embodiments, the push rod 21 may be provided with a contact ball that contacts the counterweight 11. The contact ball ensures that the push rod 21 and the counterweight 11 are in point contact, reducing the friction between the counterweight 11 and the push rod 21. The push rod 21 may be located in the upper part 231.

[0069] The technical solution of the present invention and its corresponding details have been described above. It is understood that the above description is only some implementation schemes of the technical solution of the present invention, and some details may be omitted in the specific implementation.

[0070] Furthermore, in some embodiments of the above invention, multiple embodiments may be combined; however, due to space limitations, all such combinations will not be listed here. Those skilled in the art can freely combine and implement the above embodiments according to their needs to obtain a better application experience.

[0071] When implementing the subject matter of this invention, those skilled in the art can obtain other detailed configurations or drawings based on the subject matter and drawings. Obviously, these details are still within the scope of the subject matter of this invention without departing from it.
