Description

Technical Field

[0001] The utility model relates to a folding umbrella, in particular to a folding umbrella quick-folding component and a quick-folding folding umbrella. Background Art

[0002] Umbrellas are essential daily necessities, providing shade and protection from the rain. Folding umbrellas are popular among users for their compact size, ease of portability, and ease of keeping the umbrella surface clean. However, when folding umbrellas, they become loose between the support frames of the foldable frame, resulting in a chaotic, wrinkled appearance. This makes it difficult to secure the umbrella with the limited length of the straps. Even if they are secured, the umbrella becomes bulging and cannot be stored in the umbrella case. To secure the umbrella in the case, the umbrella surface must be manually creased to fold it along regular creases. Then, it must be wound and tied to form a tight, regular shape before it can be easily stored in the case. This crease-finishing process is time-consuming and, especially after rain, can easily stain hands, causing significant trouble for users trying to fold and store the umbrella.

[0003] Since it is difficult to form a straight and regular folded state after folding and difficult to store, some people who are pressed for time or lack patience are forced to leave the umbrella in a loose state without any binding. This can easily cause damage to the foldable frame, and can also easily cause the umbrella to be contaminated and damaged, and also affect carrying it outside. Utility Model Content

[0030] In order to more clearly understand the technical content of the present invention, the following embodiments are provided for detailed explanation. Their purpose is only to better understand the content of the present invention and not to limit the scope of protection of the present invention. The components in the structures of the embodiment drawings are not scaled according to the normal proportion and therefore do not represent the actual relative sizes of the various structures in the embodiment.

[0031] Embodiment: A folding umbrella quick-folding assembly includes an upper fixing plate 1 and a lower fixing plate, which are arranged to extend horizontally along the circumferential direction of the umbrella surface 5 and vertically along the radial direction of the umbrella surface 5. The two ends of the upper fixing plate 1 can be folded along the vertically extending creases. The lower fixing plate is located on one side of the upper fixing plate 1 vertically. The lower fixing plate and the upper fixing plate can be folded along the horizontally extending crease or the horizontally extending gap formed therebetween, and there is an elastic force between the lower fixing plate and the upper fixing plate 1 that causes them to approach each other in one direction to form a folded state.

[0032] In the absence of external force, the lower fixing piece and the upper fixing piece 1 are in a folded state with the transversely extending crease or gap between them as the center surface. At this time, the lower fixing piece can form a folding angle of 0 to 90 degrees with the inner side or outer side surface of the upper fixing piece 1 as needed. When in use, the upper fixing piece 1 and the lower fixing piece are attached to the umbrella surface 5 of the folding umbrella, the lower fixing piece is attached to the first circle 51 (the outermost circle) of the folding umbrella, and the upper fixing piece 1 is attached to the second circle 52 (the circle adjacent to the outermost circle) of the folding umbrella. When the folding umbrella is opened, the upper fixing piece 1 and the lower fixing piece are unfolded by the pulling force of the umbrella surface 5. After the umbrella is folded, the lower fixing piece automatically folds under the action of its own elastic force, so that the umbrella surface 5 is folded synchronously with the lower fixing piece. At the same time, the upper fixing piece 1 makes the umbrella surface 5 fold flat in the horizontal direction, and the lower fixing piece makes the outermost circle of the folding umbrella automatically retract vertically toward the umbrella handle, thereby making the folding umbrella fold quickly and synchronously in the horizontal and vertical directions. After folding, the fabric of the umbrella surface 5 is flat and fits well, and can be directly tied and stored. This structure can be applicable to various multi-fold umbrellas such as two-fold, three-fold, four-fold, and five-fold umbrellas, ensuring that folding umbrellas of various specifications automatically fold and fold flat after folding. It can be directly fixed and flatly attached to the umbrella surface 5 during the production of the folding umbrella to form a quick-folding folding umbrella, and can also be sold separately for consumers to modify existing ordinary folding umbrellas, so that ordinary folding umbrellas have the effects of quick folding and smooth folding, avoiding the waste of ordinary umbrellas and reducing the economic burden of consumers.

[0033] The upper fixing plate 1 is an integrally formed V-shaped elastic sheet, and the two side walls of the V-shaped elastic sheet can swing elastically relative to each other to change the angle between the two. There is an elastic force between the two side walls of the V-shaped elastic sheet of the upper fixing plate, which are relatively close to each other in one direction to form a folded state. The side walls of the V-shaped elastic sheet of the upper fixing plate 1 have a set hardness and can produce curling deformation under the action of external force.

[0034] During the relative elastic swing of the two side walls of the V-shaped elastic sheet, the angle between the two side walls of the V-shaped elastic sheet changes between 0° and 180°, and then the two side walls of the V-shaped elastic sheet change between the folded and overlapped states and the flattened state. In the absence of external force, the V-shaped elastic sheet serving as the upper fixing sheet 1 is in a folded state with the vertically extending crease as the center plane. When the V-shaped elastic sheet serving as the upper fixing sheet 1 is in the folded state, the angle between its two side walls is 0° to 90°, and the best state is a flat state. This structure enables the upper fixing sheet itself to have an automatic elastic folding state, which is beneficial for the part of the umbrella surface with the upper fixing sheet to automatically fold in one direction after the umbrella is folded, so that the umbrella surface is folded together flatly. In addition to adopting the V-shaped spring structure, the upper fixing sheet 1 can also be two sheets with a certain hardness that can be curled and deformed by external force, and a torsion spring, C The C-shaped elastic buckle and the V-shaped elastic buckle cooperate, and the two sheets are respectively fixedly installed at the two ends of the torsion spring, the C-shaped elastic buckle and the V-shaped elastic buckle elastic swing, which can also realize the automatic elastic swing and folding of the upper fixing plate 1 after the umbrella is folded. In addition, the two sheets can be set at intervals or a flexible crease can be formed in the middle of the two sheets. The two sheets are fixedly connected to the two ends of the spring or elastic rope, and the two sheets are pulled by the spring or elastic rope to swing and fold relative to each other. Of course, the upper fixing plate may not have the elastic swing and folding function. It only plays a supporting role for the umbrella surface, so that the umbrella surface remains flat after the umbrella is folded. However, this method does not have the elastic folding function of the upper fixing plate, which is more conducive to the umbrella surface folding flat in an orderly manner according to rules. The above structures are equivalent replacement structures that can be easily thought of by those skilled in the art based on this application, and all fall within the scope of protection of this application.

[0035] The upper fixing plate 1 is provided with a vertically extending U-shaped notch 11. The U-shaped notch 11 is located at one end of the fold of the V-shaped elastic sheet facing away from the lower fixing plate, so that the length of the fold in the middle of the V-shaped elastic sheet is shorter than the vertical length of the upper fixing plate 1. During use, the provision of the U-shaped notch 11 can reduce the length of the middle bend, thereby avoiding any impact on the vertical fold 53 of the umbrella cover 5. This ensures that the umbrella cover 5 folds tightly after folding, and minimizes the diameter of the umbrella after bundling. The depth of the U-shaped notch 11 can be designed according to actual conditions to ensure sufficient elastic force to enable the two side walls of the upper fixing plate 1 to pull the umbrella cover 5 to fold flat, while also reducing the thickness of the folded base of the umbrella cover 5. When the upper fixing plate does not have elastic rebound to achieve automatic folding, the upper fixing plate can also be separated into two separate pieces, forming a vertically extending gap between the two pieces. This gap serves as the vertically extending fold between the two ends of the upper fixing plate.

[0036] The lower fixing plate includes a V-shaped elastic strip 2 with a set hardness. The two ends of the V-shaped elastic strip 2 can swing elastically relative to each other to change the angle between the two. One end of the V-shaped elastic strip 2 is fixedly connected to the fold portion extending vertically on the upper fixing plate 1 by integral molding or split assembly.

[0037] During the relative elastic swinging of the two side walls of the V-shaped elastic strip 2, the angle between the two sections of the V-shaped elastic strip 2 changes between 0° and 180°, and then the two side walls of the V-shaped elastic strip 2 change between the folded and overlapped states and the flattened state, that is, the lower fixing plate and the upper fixing plate 1 are folded and unfolded. The above-mentioned V-shaped elastic strip can be an integral structure, or it can be composed of two narrow plates or linear materials with a certain hardness in conjunction with a torsion spring, a C-shaped elastic clip and a V-shaped elastic clip. The two narrow plates or linear materials are respectively fixedly installed at the two ends of the torsion spring, the C-shaped elastic clip and the V-shaped elastic clip to elastically swing, so that the lower fixing plate can automatically swing and fold after the umbrella is folded. In addition, the V-shaped elastic strip can also be composed of two narrow plates or two wires with a flexible fold or interval formed in the middle. The two narrow plates or wires are fixedly connected to the two ends of the spring or elastic rope, and the two narrow plates or wires are pulled by the spring or elastic rope to swing and fold relative to each other. Such equivalent replacement structures are easily conceivable by those skilled in the art based on the present application and all fall within the scope of protection of the present application.

[0038] The vertically extending fold between the ends of the upper fixing plate 1 is a flat structure or an arc-shaped structure with a set width, and the cross-section of the V-shaped elastic strip 2 is a flat structure, an arc-shaped structure, or a cylindrical structure that matches the fold. The above structure facilitates the secure connection and positioning of the V-shaped elastic strip 2 and the fold between the ends of the upper fixing plate 1. The V-shaped elastic strip 2 and the fold between the ends of the upper fixing plate 1 can be fixed by bonding, welding, or an integrally formed structure, or can also be fixed by riveting. After seeing this application, those skilled in the art can design it according to their needs, and all of these fall within the scope of protection of this application.

[0039] The lower fixing plate also includes support plates 3. Two support plates 3 are distributed on both sides of the other end of the V-shaped elastic strip 2. The two support plates 3 can be folded with the other end of the V-shaped elastic strip 2 as the crease. The support plates 3 located on both sides of the other end of the V-shaped elastic strip 2 have a set hardness, and the support plates 3 can be curled and deformed when subjected to external forces. The support plates 3 can support the umbrella cover 5 on both sides of the V-shaped elastic strip 2, so that the outer umbrella cover 5 remains flat and folded after the umbrella is folded. The support plates 3 and the other end of the V-shaped elastic strip 2 can be fixed by bonding, welding, riveting, or integrally formed. After seeing this application, those skilled in the art can design according to their needs, and all of these fall within the scope of protection of this application.

[0040] The two support sheets 3 are formed as an integrally formed V-shaped elastic sheet. The two support sheets 3 can elastically swing relative to each other along vertically extending folds to change the angle between them. The folding direction of the support sheets 3 is opposite to the folding direction of the upper fixing sheet 1. The other end of the V-shaped elastic strip 2 is fixedly connected to the vertically extending fold on the support sheet 3 of the V-shaped elastic sheet structure through an integral molding method or a separate assembly method. The support sheets 3 of this structure not only support the outer umbrella cover 5 but also drive the outer umbrella cover 5 to automatically fold, further improving the folding flatness of the umbrella cover 5 after the folding umbrella is folded. This structure makes multi-fold umbrellas such as three-fold umbrellas, four-fold umbrellas, and five-fold umbrellas fold more smoothly and compactly, and avoids the outer umbrella cover 5 being unevenly flat due to the upper fixing sheet 1's elastic folding force insufficient to pull the outer umbrella cover 5 to fold synchronously when the umbrella is folded.

[0041] Two support pieces 3 are provided on either side of the other end of the V-shaped elastic strip 2. The two support pieces 3 are spaced apart from the other side of the V-shaped elastic strip 2, or the two support pieces 3 are connected to the other side of the V-shaped elastic strip 2 via a flexible structure. The support pieces 3 of this structure primarily support the umbrella canopy 5, ensuring that the outer ring of the umbrella canopy 5 remains flat after the umbrella is folded. The two support pieces 3 can also be elastically folded using a torsion spring, a V-shaped buckle, a C-shaped buckle, a tension spring, an elastic cord, or the like.

[0042] The upper and lower fixing plates 1 and 2 are provided with an adhesive layer or solder layer on the same side, with a release film 4 attached to the adhesive layer or solder layer. This structure allows the quick-closing assembly of a folding umbrella to be packaged and sold separately. To use the assembly, simply remove the release film 4 and apply it flatly to the canopy 5 of a standard folding umbrella. The quick-closing assembly can be directly attached to the canopy 5 using the adhesive layer, welded to the canopy 5 using the solder layer, or secured by other means.

[0043] A quick-folding umbrella comprises a folding umbrella and a quick-folding assembly for the folding umbrella, wherein the umbrella surface 5 is divided into several annular areas by several transverse folds 54 extending along the circumferential direction of the umbrella surface 5, the annular area farthest from the center of the umbrella surface 5 is set as the first circle 51, and the annular area adjacent to the first circle 51 is set as the second circle 52, the lower fixing plate of the folding umbrella quick-folding assembly is fixed and flat on the surface of the first circle 51 of the folding umbrella surface 5, the upper fixing plate 1 is fixed and flat on the surface of the second circle 52 of the folding umbrella surface 5, and the vertically extending folds on the upper fixing plate 1 are aligned with the vertical folds 53 between adjacent ribs 6 on the folding umbrella surface 5, the transversely extending folds or transversely extending gaps formed between the lower fixing plate and the upper fixing plate 1 are aligned with the transverse folds 54 between adjacent ribs 6 on the folding umbrella surface 5, and the parts of the lower fixing plate located on both sides of the vertical folds 53 on the folding umbrella surface 5 can be folded along the vertical folds 53 synchronously with the umbrella surface 5.

[0044] It is best for the upper fixing piece 1 to cover the second circle 52 area of ​​the folding umbrella as much as possible, and a gap is formed between adjacent upper fixing pieces 1 that is opposite to the ribs 6 on the umbrella surface 5. The vertical fold 53 in the middle of the upper fixing piece 1 is just opposite to the vertical fold 53 between adjacent ribs 6 on the umbrella surface 5. There is a certain gap between the horizontal edge of the upper fixing piece 1 and the horizontal folds 54 on both sides of the second circle 52 of the umbrella surface 5. This can avoid affecting the smooth folding of the umbrella surface 5 along the folding folds, and at the same time ensure that the umbrella surface 5 is flat after folding. The lower fixing piece is correspondingly attached to the surface of the first circle 51 of the folding umbrella, and the V-shaped elastic strip 2 of the lower fixing piece is aligned with the vertical fold 53 in the middle of the adjacent ribs 6 in the first circle 51 of the umbrella surface 5. The supporting piece 3 of the lower fixing piece does not need to fill the first circle 51 area of ​​the umbrella surface 5 to prevent the radial dimension of the folding umbrella from increasing after being tied, so that the diameter of the folding umbrella is as small as possible after being folded and tied.

[0045] The above embodiments are a detailed description of the preferred embodiments of the present invention with reference to the accompanying drawings. Those skilled in the art may make various modifications or changes to the above embodiments without departing from the essence of the present invention, and all such modifications or changes fall within the scope of protection of the present invention.
