Description

Technical Field

[0001] This utility model relates to a component of an umbrella for everyday use, and in particular to an improved structure of a honeycomb that is connected to the umbrella ribs and is rotatable. Background Technology

[0002] Currently, there is a type of umbrella on the market with a rotating canopy. This involves a rotating ring-shaped section on the honeycomb pattern of the umbrella that connects to the ribs. When the canopy hits an object, it rotates. This rotating honeycomb design not only reduces the risk of injury from collisions but also adds dynamism and aesthetics. However, in this type of umbrella, the ring-shaped section still rotates during closing, and therefore the ribs also rotate. This makes rolling up the umbrella inconvenient, as the ribs and fabric rotate with the force applied by the user. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a rotating honeycomb that can prevent the ring part of the honeycomb from rotating when closing the umbrella, making it more convenient to close the umbrella.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is to design and manufacture a rotating honeycomb, including: an upper honeycomb installed on the top of the center rod of the umbrella, and a lower honeycomb slidably sleeved outside the center rod; the upper honeycomb includes an upper honeycomb body and an upper ring honeycomb portion rotatably installed on the upper honeycomb body, and the lower honeycomb includes a lower honeycomb body and a lower ring honeycomb portion rotatably installed on the lower honeycomb body; the upper ring honeycomb portion and the lower ring honeycomb portion are connected to the umbrella ribs; The inner wall of the lower ring nest is provided with a plurality of inwardly protruding inner protrusions along the circumference, and the top of the inner protrusions is inclined; an outer sleeve is slidably fitted onto the lower nest body, and the outer sleeve is provided with an outer protrusion close to the inner wall of the lower ring nest, and the bottom of the outer protrusion is inclined; When the umbrella is open, the outer and inner protrusions are staggered vertically, allowing the lower ring nest section to rotate relative to the lower nest body. When the outer sleeve is pulled down to close the umbrella, the outer protrusion moves down and inserts between two adjacent inner protrusions, preventing the lower ring nest section from rotating relative to the lower nest body.

[0005] The lower nest body has an outwardly protruding upper edge and a middle boss on its side wall. The lower ring nest is slidably fitted onto the middle boss, and the inner protrusion is located between the upper edge and the middle boss.

[0006] The outer sleeve is fitted under the central boss of the lower nest body. The top of the outer sleeve is provided with an upwardly extending insert. The insert passes upward through the through hole opened on the central boss. The outer protrusion is provided on the outer side wall of the insert.

[0007] The outer sleeve is provided with two radially opposite inserts and two external protrusions.

[0008] The top surface of the upper convex edge is a slope that gradually decreases outwards. The upper side wall of the lower nest body is provided with several vertical through grooves that extend to the top. The bottom surface of the inner protrusion is provided with a slope or an arc surface.

[0009] A bottom ring is fixedly fitted at the bottom of the lower nest body, and a spring is installed in the lower inner cavity of the outer sleeve. The bottom of the spring is supported by the bottom ring, and the top pushes the outer sleeve upward.

[0010] The lower nest is a push-pull type lower nest. A rotating buckle is rotatably installed at the buckle through hole opened on the side wall of the lower nest body. The inner wall of the outer sleeve has a raised step corresponding to the rotating buckle and a recess above the raised step that can accommodate the rotating buckle. Pushing the outer sleeve upward causes the convex step to rotate the rotating buckle inward; pulling the outer sleeve downward causes the rotating buckle to rotate outward to the recessed position under the push of the side wall of the middle rod.

[0011] The top of the inner protrusion and the bottom of the outer protrusion are sharp angles formed by two inclined surfaces.

[0012] The bottom center of the upper ring nest is provided with a downward-extending shaft post, and the lower part of the shaft post is provided with an outwardly protruding enlarged head with a larger diameter; the middle part of the upper nest body is provided with a vertical shaft hole, the upper part of the vertical shaft hole has a smaller inner diameter and the lower part has a larger inner diameter, and a variable step is formed at the junction of the upper and lower parts, and the enlarged head is stuck at the variable step.

[0013] Compared with the prior art, the rotating honeycomb of this utility model uses an inner protrusion on the inner wall of the lower ring honeycomb part and an outer protrusion on the outer sleeve to cooperate with each other. When the umbrella is open, the inner and outer protrusions are staggered vertically and will not affect the rotation of the lower ring honeycomb part and the umbrella ribs. When the outer sleeve is pulled down to close the umbrella, the outer protrusion will insert between the adjacent inner protrusions to prevent the lower ring honeycomb part and the umbrella ribs from rotating. Therefore, when the lower honeycomb is pulled down, the umbrella ribs will not be affected by rotation and the closing of the umbrella will be more convenient. Attached Figure Description

Detailed Implementation

[0015] The preferred embodiment shown in the accompanying drawings will be described in further detail below.

[0016] like Figure 1 , Figure 2 and Figure 3 As shown, the rotating honeycomb of this invention includes an upper honeycomb 2 and a lower honeycomb 3. The upper honeycomb 2 is mounted on the top of the umbrella's central rod 1 and includes an upper honeycomb body 21 and an upper ring honeycomb portion 22 rotatably mounted on the upper honeycomb body 21. The lower honeycomb 3 is slidably sleeved on the outside of the central rod 1 and includes a lower honeycomb body 31 and a lower ring honeycomb portion 32 rotatably mounted on the lower honeycomb body 31. The umbrella rib 4 is connected to the upper ring honeycomb portion 22 and the lower ring honeycomb portion 32, so that when the upper ring honeycomb portion 22 and the lower ring honeycomb portion 32 are in a rotatable state, the umbrella rib 4 can also rotate accordingly.

[0017] Wherein, the upper nest 2 can adopt an existing rotating umbrella upper nest structure. In this embodiment, such as Figure 2 and Figure 6 As shown, the bottom center of the upper annular nest portion 22 is provided with a downwardly extending shaft post 221, and the lower part of the shaft post 221 is provided with an outwardly protruding enlarged head 222 with a larger diameter. The middle part of the upper nest body 21 is provided with a vertical shaft hole 211. The upper inner diameter of the vertical shaft hole 211 is smaller and the lower inner diameter is larger, forming a variable step position 212 at the junction of the upper and lower parts. In addition, the upper sidewall of the upper nest body 21 has several vertical slots 213, thus having the elasticity to retract inward or expand outward. The enlarged head 222 is squeezed into the vertical shaft hole 211 of the upper nest body 21 from top to bottom and finally locked at the variable step position 212, so that the upper annular nest portion 22 can rotate relative to the upper nest body 21.

[0018] In this embodiment, the lower nest 3 adopts a push-pull lower nest structure, such as... Figure 3As shown, the lower nest 3 includes: a lower nest body 31, a lower ring nest part 32 movably sleeved on the upper part of the lower nest body 31, an outer sleeve 33 slidably sleeved on the lower part of the lower nest body 31, a bottom ring 34, a spring 35, and a rotating buckle 36. The umbrella can be opened or closed by pushing or pulling the outer sleeve 33.

[0019] like Figure 5 As shown, the upper sidewall of the lower nest body 31 is provided with an outwardly protruding upper flange 311 and a middle flange 312 respectively. The lower nest body 31 has a square fastening through hole 314, a limiting protrusion 316 and a buckling through hole 315 on the front and rear sidewalls below the middle flange 312, respectively.

[0020] like Figure 4 As shown, the lower ring nest 32 is annular, and its exterior is provided with a concave-convex structure for connecting the umbrella ribs 4. The lower part of its inner wall is uniformly provided with a plurality of, for example, eight, inwardly protruding inner protrusions 321 along the circumference. The top of the inner protrusion 321 is set as a slope, preferably a pointed angle composed of two slopes.

[0021] like Figure 6 and Figure 7 As shown, the lower ring nest portion 32 is fitted onto the central boss 312 of the lower nest body 31, and the inner protrusion 321 is located between the upper protrusion 311 and the central boss 312, thereby allowing the lower ring nest portion 32 to rotate relative to the lower nest body 31. For ease of assembly, as... Figure 3 and Figure 5 As shown, the top surface of the upper convex edge 311 is a slope that gradually decreases outward, and the upper side wall of the lower nest body 31 is provided with several vertical through grooves 313 that extend to the top, thus having the elasticity to shrink inward or expand outward. The bottom surface of the inner protrusion 321 is set as a slope or an arc surface.

[0022] The outer sleeve 33 is fitted below the central protrusion 312 of the lower nest body 31, such as... Figure 3 The outer sleeve 33 has upwardly extending inserts 332 on both the left and right sides of its top. The top of the outer wall of each insert 332 has an outwardly protruding protrusion 331. The bottom of the protrusion 331 is set as an inclined surface, preferably a pointed angle composed of two inclined surfaces. The inserts 332 on the left and right sides pass upward through the through holes opened on the central boss 312, thereby allowing the outer sleeve 33 to slide up and down relative to the lower nest body 31.

[0023] like Figure 3 , Figure 6 and Figure 7As shown, the bottom ring 34 is annular, with a snap-fit ​​protrusion 341 on each of its front and rear inner walls. The bottom ring 34 is fitted over the bottom of the lower nest body 31 from bottom to top, and the two snap-fit ​​protrusions 341 respectively engage with the two snap-fit ​​through holes 315 on the side wall of the lower nest body 31, thereby fixing the bottom ring 34 to the bottom of the lower nest body 31. In order to enable the bottom ring 34 to be smoothly fitted onto the lower nest body 31, the top surface of the snap-fit ​​protrusion 341 is set as a slope, and the lower side wall of the lower nest body 31 has several vertical elongated slots 317, thus having the elasticity to retract inward or expand outward.

[0024] The spring 35 is installed in the cavity between the outer sleeve 33 and the lower nest body 31. The bottom of the spring 35 is supported by the bottom ring 34, and the top pushes the inner wall of the outer sleeve 33 upward. Thus, without external force, the outer sleeve 33 will be pushed upward to abut against the central boss 312. At this time, if Figure 6 As shown, the outer protrusion 331 and the inner protrusion 321 are staggered vertically, and the lower ring nest portion 32 can rotate relative to the lower nest body 31.

[0025] like Figure 3 and Figure 7 As shown, two rotating buckles 36 are provided, which are rotatably installed at the buckle through holes 314 opened on the front and rear side walls of the lower nest body 31 via rotating shafts. The cross-section of the rotating buckle 36 is approximately fan-shaped, with two mutually perpendicular planes and an arc surface connecting the two planes. The top of the inner wall of the outer sleeve 33 has a raised step 333 at the position corresponding to the rotating buckle 36, and a recess 334 is formed above the raised step 333 to accommodate the rotating buckle 36. The upper part of the side wall of the middle rod 1 has a positioning hole 11 at the position corresponding to the rotating buckle 36 for the rotating buckle 36 to enter so that the lower nest can be locked when the umbrella is opened.

[0026] Push the outer sleeve upwards to open the umbrella until it opens like this. Figure 6 and Figure 7 In the open umbrella position shown, the lower nest 3 moves upward until the position of the rotating buckle 36 is horizontally opposite to the positioning hole 11 on the side wall of the middle rod. The rotating buckle 36 is pushed inward by the protrusion 333 on the inner wall of the outer sleeve 33 and enters the positioning hole 11 until one plane of the rotating buckle 36 abuts against the bottom of the positioning hole 11 and the other plane abuts against the inner wall of the outer sleeve 33. The spring 35 pushes the outer sleeve 33 upward to prevent it from sliding down, thereby preventing the rotating buckle 36 from rotating outward and locking the lower nest 3 in the open umbrella position. At the same time, the outer protrusion 331 on the top of the insert 332 is offset vertically from the inner protrusion 321 on the inner wall of the lower ring nest 32, and the lower ring nest 32 and the umbrella rib 4 can rotate.

[0027] When pulling down the outer sleeve 33 to prepare to close the umbrella, as Figure 8 and Figure 9As shown, the rotating buckle 36 gradually rotates outward into the recess 334 due to the downward movement of the outer sleeve 33 and the contact with the bottom of the center rod positioning hole 11. At the same time, the outer protrusion 331 on the top of the insert 332 moves downward and inserts between two adjacent inner protrusions 321 on the inner wall of the lower ring nest 32. At this time, the lower ring nest 32 and the umbrella rib 4 cannot rotate, making the umbrella closing action smoother. The sharp angle design of the bottom of the outer protrusion 331 and the top of the inner protrusion 321 allows the outer protrusion 331 and the inner protrusion 321 to be offset by relative sliding on the inclined surface when the outer sleeve 33 moves downward.

[0028] When you continue to pull the outer sleeve 33 downwards until the lower nest 3 is completely away from the open umbrella position, as Figure 10 and Figure 11 As shown, when the rotating buckle 36 is in the open position, it rotates outward by approximately 90 degrees, and its outer part enters the recess 334. At this time, it is blocked by the side wall of the central rod 1, and the rotating buckle 36 cannot rotate inward. The outer sleeve 33 also cannot move upward due to the obstruction of the rotating buckle 36, so that the outer protrusion 331 and the inner protrusion 321 remain at the same horizontal position. As a result, the lower ring nest part 32 and the umbrella rib 4 cannot rotate. The limiting protrusion 316 protruding from the side wall of the lower nest body 31 at this time abuts against the inner wall of the outer sleeve 33, which can prevent the outer sleeve 33 from continuing to slide down and detaching from the lower nest body 31.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
