Description

Technical Field

[0001] The present invention belongs to the field of umbrella accessories, and particularly relates to a protective structure for an umbrella nest. Background Art

[0002] Umbrellas are a commonly used daily necessity for people. Currently, most of the umbrellas sold on the market use iron or aluminum alloy as the umbrella frame. Among them, the umbrella ribs need to be inserted into the umbrella nest to form a support structure, and the umbrella nest and the umbrella ribs are bound together with iron wire. To ensure that the umbrella ribs have sufficient rotation space during the opening and closing processes of the umbrella, when the connecting section of the umbrella ribs and the umbrella nest is in the closed state, the umbrella ribs are usually partially exposed outside the umbrella nest, forming sharp protrusions, which are extremely easy to abrade or puncture the umbrella cloth or the umbrella ribs; although the existing umbrellas perform passivation treatment on the protruding part of the umbrella ribs, the problem still cannot be completely solved, and the umbrella cloth is still damaged or the umbrella ribs are damaged during transportation or after long-term use; especially under the impetus of the demand for smaller-sized umbrellas, the requirement for the closing tightness of the umbrella is higher, and the frequency of customer complaints caused by such abrasion and puncture is also increasing, seriously affecting the customer experience.

[0003] To solve this problem, when the existing commercially available umbrellas leave the factory, soft materials such as elastic cotton or cloth are manually padded at the joint of the umbrella ribs and the umbrella nest. This method has the following disadvantages: First, it increases the labor cost of umbrella manufacturing; second, during daily use, the elastic cotton or cloth is easily detached and cannot form long-term protection, so it usually only plays a protective role during transportation and will be discarded after reaching the destination. The discarded protective material becomes waste, which does not conform to the environmental protection concept; third, after the protective material is removed or detached, the joint of the umbrella ribs and the umbrella nest is exposed, and the iron wire interface used to bind the umbrella ribs is also correspondingly exposed outside (some umbrella products will set a protective sleeve outside the iron wire interface, but there is still a problem that the protective sleeve is easily detached), lacking effective and long-term protection, the product quality is easily damaged and there are potential safety hazards such as scratches during use; especially when the products are sold to countries with higher requirements for product safety and environmental protection such as Japan, the United Kingdom, and the United States, the aforementioned disadvantage two results in the export products not meeting the environmental protection standards, constituting a restriction on product exports, and the aforementioned disadvantage three results in the export products not meeting the quality or safety standards, becoming the main reason for mass returns of products. Summary of the Invention

[0004] To solve the situation that the joint of the umbrella ribs and the umbrella nest in the closed state of the existing umbrellas is prone to abrading or puncturing the umbrella cloth or the umbrella ribs, the present invention proposes a protective structure for an umbrella nest, which has the characteristics of simple structure, long-term protection, and controllable manufacturing cost.

[0005] The present invention is realized through the following technical solutions:

[0006] The present invention provides a protective structure for an umbrella nest, which includes a lower umbrella nest and an elastic protective sleeve. The lower umbrella nest includes a nest body and an extension section. A fixing structure for preventing the elastic protective sleeve from sliding down is provided on the extension section. The elastic protective sleeve is sleeved outside the nest body, and a necking section for cooperating with the fixing structure is provided at the lower end of the elastic protective sleeve.

[0007] Based on the above technical solution, by sleeving an elastic protective sleeve outside the lower umbrella nest and cooperatively arranging an anti-sliding fixing structure on the lower end of the protective sleeve and the extension section of the lower umbrella nest, when the umbrella is opened, it does not interfere with the outward expansion of the umbrella ribs and the protective sleeve does not slide downwards. When the umbrella is closed, the joint part of the umbrella ribs and the nest body is completely wrapped in the protective sleeve, separated from the umbrella cloth and other umbrella ribs, achieving an effective protection effect.

[0008] Further, the extension section is externally threaded and connected with a sleeve to form the fixing structure. The necking section of the elastic protective sleeve is clamped to the lower end of the nest body through the sleeve. This structure has good installation characteristics and facilitates the simplification of the processing technology.

[0009] Further, a necking groove is opened at the connection between the extension section and the nest body. This structure does not require additional components, can be integrally formed during the production of the lower nest body, and saves part of the material usage.

[0010] Further, a limiting structure is convexly provided below the nest body on the extension section to form the fixing structure. This structure does not require additional components, can be integrally formed during the production of the lower umbrella nest, and can be directly modified on the original production mold of the lower umbrella nest, with a relatively low modification cost.

[0011] Preferably, the limiting structure is a ring-shaped protrusion provided on the extension section.

[0012] Preferably, the limiting structure is a plurality of positioning protrusions or positioning bumps arranged circumferentially around the extension section.

[0013] Further, the necking section is formed by the inward extension of the lower end of the elastic protective sleeve, and the necking section is embedded in the fixing structure. This structure realizes the effect of preventing the elastic protective sleeve from sliding down by the inward contraction of the lower end of the elastic protective sleeve and its embedding in the necking groove for limiting.

[0014] Further, the necking section of the elastic protective sleeve is formed by the downward extension of the elastic protective sleeve. The inner diameter of the necking section is slightly larger than the outer diameter of the extension section. The necking section is sleeved on the extension section, and the necking section is wrapped in the sleeve to form the limitation of the elastic protective sleeve.

[0015] Furthermore, the necking section of the elastic protective cover extends downward from the elastic protective cover. The inner diameter of the necking section is slightly larger than the outer diameter of the extension section. The necking section is sleeved on the extension section, and the necking section is arranged to wrap the limiting structure. This structure wraps the limiting structure of the lower umbrella nest through the necking section. The necking section is pushed open outward and generates an inward contraction force under the action of elastic force, thereby achieving the effect of preventing the elastic protective cover from sliding down.

[0016] Furthermore, the material of the elastic protective cover is silicone, which has good softness and wear resistance, or the material of the elastic protective cover is a heat-shrinkable elastic material such as PE or silicone rubber. This material can enlarge the size of the elastic protective cover before processing, facilitate reducing the processing difficulty, and enable the processed elastic protective cover to have better fit and aesthetics with the lower umbrella nest, and also facilitate the miniaturized storage of the umbrella.

[0017] Beneficial Effects

[0018] One of the above technical solutions has the following advantages or beneficial effects:

[0019] 1) By sleeving an elastic protective cover on the lower umbrella nest and cooperatively arranging an anti-slip fixing structure on the lower end of the protective cover and the extension section of the lower umbrella nest, it does not interfere with the outward expansion of the umbrella ribs when the umbrella is opened and the protective cover does not slide downward. When the umbrella is closed, the joint part of the umbrella ribs and the nest body is completely wrapped in the protective cover, separated from the umbrella cloth and other umbrella ribs, achieving an effective protection effect, especially for multi-fold umbrellas and umbrellas pursuing miniaturization, the effect is more significant.

[0020] 2) By setting the necking section of the elastic protective cover as an inward-extending circle and fixing it in cooperation with the necking groove, sleeve or limiting structure on the lower umbrella nest, the structure is simple, the anti-slip effect is good, and it has good processability.

[0027] The present invention will be further described in detail below in conjunction with embodiments, but the implementation modes of the present invention are not limited thereto.

[0028] Embodiment 1

[0029] This embodiment proposes a protective structure for an umbrella nest, including a lower umbrella nest 100 and an elastic protective sleeve 200. The lower umbrella nest 100 includes a nest body 101 and an extension section 102. A fixing structure 10 for preventing the elastic protective sleeve 200 from sliding down is provided on the extension section 102. The elastic protective sleeve 200 is sleeved outside the nest body 101. A necking section 20 cooperating with the fixing structure 10 is provided at the lower end of the elastic protective sleeve 200. The inner diameter of the necking section 20 can be between the outer diameter of the extension section 102 and the outer diameter of the nest body 101 to improve the convenience of manufacturing, or the inner diameter of the necking section 20 can also be smaller than the outer diameter of the extension section 102 to increase the adhesion of the elastic protective sleeve 200 on the umbrella nest. The elastic protective sleeve 200 is made of a silicone material with good softness and wear resistance.

[0030] As Figure 1 shown, the necking section 20 is a circle formed by the inward extension of the lower end of the elastic protective sleeve 200. The fixing structure 10 is a sleeve 12 threadedly connected to the external thread of the extension section 102. The necking section 20 is clamped to the lower end of the nest body 101 by the sleeve 12 to prevent the elastic protective sleeve 200 from sliding down. Specifically, the fixing structure 10 is: the extension section 102 is provided with an external thread at a position at a certain distance from the lower end of the nest body 101 and is threadedly connected with a sleeve 12. An internal thread matching the external thread is opened in the sleeve 12. After the elastic protective sleeve 200 is sleeved on the lower umbrella nest 100, the necking section 20 wraps the lower end face of the nest body 101 and is clamped and fixed on the lower end face of the nest body 101 by the sleeve 12. This structure has good installation characteristics and relatively simple processing technology. As a feasible implementation mode, the necking section 20 can also be formed by the downward extension of the lower end of the elastic protective sleeve 200. The necking section 20 is sleeved on the extension section 102 and wrapped in the sleeve.

[0031] Embodiment 2

[0032] This embodiment proposes a protective structure for an umbrella nest, which is different from the previous embodiment in that:

[0033] As Figure 2As shown, the necking section 20 is a ring formed by the inward extension of the lower end of the elastic protective sleeve 200. The fixing structure 10 is a circular groove formed at the connection of the extension section 102 and the nest body 101. The necking section 20 also correspondingly extends more into the necking groove 11. This structure does not require additional components and can be integrally formed during the production of the lower nest body 101, saving some material usage.

[0034] Embodiment 3

[0035] This embodiment proposes a protective structure for an umbrella nest, which is different from the previous embodiments in that:

[0036] The fixing structure 10 is a limiting structure 13 protruding below the nest body 101 on the extension section 102. The limiting structure 13 is a circular protrusion provided on the extension section 102 or several positioning bumps or positioning points arranged circumferentially around the extension section 102. This structure does not require additional components and can be integrally formed during the production of the lower nest body 101, and can be directly modified using the original production mold of the lower umbrella nest 100, with a relatively low modification cost.

[0037] One implementation based on the above technical solution is: As Figure 3 shown, the necking section 20 is a ring formed by the inward extension of the lower end of the elastic protective sleeve 200. A circular groove is formed between the limiting structure 13 and the nest body 101, and the necking section 20 is embedded in the circular groove to form a limit.

[0038] Another implementation based on the above technical solution is: As Figure 4 shown, the necking section 20 of the elastic protective sleeve 200 is formed by the downward extension of the elastic protective sleeve 200. The necking section 20 is sleeved on the extension section 102 and wraps the limiting structure 13. This structure wraps the limiting structure 13 of the lower umbrella nest 100 through the necking section 20, and the necking section 20 is pushed outwards and generates an inward contraction force under the action of elastic force, thereby achieving the effect of preventing the elastic protective sleeve 200 from slipping down.

[0039] Embodiment 4

[0040] This embodiment proposes a protective structure for an umbrella nest, which is different from the previous embodiments in that:

[0041] The elastic protective sleeve 200 is made of heat-shrinkable elastic materials such as PE and silicone rubber. This material allows the elastic protective sleeve 200 to be appropriately enlarged in size during production so that the elastic protective sleeve 200 can be easily sleeved onto the lower umbrella nest 100, and the elastic protective sleeve 200 is tightly attached to the lower umbrella nest 100 through heat shrinkage, with better durability and aesthetics.

[0042] The above are only the preferred embodiments of the present invention, and do not impose any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the present invention.
