Description

Technical Field

[0001] The invention relates to a folding umbrella, in particular to a folding umbrella quick-folding assembly and a quick-folding folding umbrella. Background Art

[0002] Umbrellas are essential daily necessities in our daily lives, providing shade and protection from rain. Folding umbrellas are small in size, easy to carry, and easy to keep clean, and are favored by the majority of users. However, when a folding umbrella is stored after use, the umbrella surface will become soft between the supporting frames of the foldable frame, causing the umbrella surface to show disorderly folds. Such an umbrella surface is difficult to be tied up with a limited length of straps. Even if it is barely tied, it becomes very bulging and cannot be put into the umbrella cover for storage. In order to store it in the umbrella cover, the umbrella surface must be manually folded so that the umbrella surface is folded according to the regular folds, and then it can be smoothly put into the umbrella cover after winding and binding to form a tight and regular shape. This arrangement process is very time-consuming on the one hand, and on the other hand, if it is after rain, it is easy to dirty people's hands, which causes great trouble for users to fold and store umbrellas.

[0003] Since it is difficult to form a straight and regular folded state after folding and is difficult to store, some people who are pressed for time or have no 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. Summary of the invention

[0010] As a further improvement of the present invention, the lower fixing plate also includes a support plate, and the two support plates are distributed on both sides of the other end of the V-shaped elastic strip. The two support plates can be folded with the other end of the V-shaped elastic strip as a crease. The support plates are located on both sides of the other end of the V-shaped elastic strip and have a set hardness, and the support plates can be curled and deformed by external force.

[0011] As a further improvement of the present invention, the two support sheets form an integrally formed V-shaped elastic sheet, and the two support sheets can elastically swing relative to each other along the vertically extending folds to change the angle between the two, and the folding direction of the support sheets is opposite to the folding direction of the upper fixed sheet, and the other end of the V-shaped elastic strip is fixedly connected to the vertically extending fold part on the support sheet of the V-shaped elastic sheet structure by an integral molding manner or a split assembly manner.

[0030] In order to more clearly understand the technical content of the present invention, the following embodiments are specifically described in detail, the purpose of which is only to better understand the content of the present invention but not to limit the scope of protection of the present invention. The components in the structure of the embodiment drawings are not scaled according to normal proportions, so they do not represent the actual relative sizes of the structures in the embodiments.

[0031] Embodiment: A folding umbrella quick-folding assembly comprises an upper fixing plate 1 and a lower fixing plate, which are arranged to extend in the circumferential direction of an umbrella surface 5 in the horizontal direction and in the radial direction of the umbrella surface 5 in the vertical direction. Both ends of the upper fixing plate 1 can be folded along a vertically extending crease. The lower fixing plate is located on one vertical side of the upper fixing plate 1. The lower fixing plate and the upper fixing plate can be folded along a horizontally extending crease or a 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 sheet and the upper fixing sheet 1 are in a folded state with the fold or gap extending laterally therebetween as the center plane. At this time, the lower fixing sheet can be folded with the inner side or outer side surface of the upper fixing sheet 1 to form a folding angle of 0 to 90 degrees as needed. When in use, the upper fixing sheet 1 and the lower fixing sheet are attached to the umbrella surface 5 of the folding umbrella, the lower fixing sheet is attached to the first circle 51 (the outermost circle) of the folding umbrella, and the upper fixing sheet 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 sheet 1 and the lower fixing sheet are unfolded by the pulling force of the umbrella surface 5. After the umbrella is folded, the lower fixing sheet automatically folds under the action of its own elastic force, so that the umbrella surface 5 is folded synchronously with the lower fixing sheet. 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 gather toward the umbrella handle in the vertical direction, so that the folding umbrella can be folded 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 are automatically folded and folded flat after the umbrellas are folded. They can be directly fixed and flattened on 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 the 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 sides. There is an elastic force between the two side walls of the V-shaped elastic sheet that 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 be curled and deformed by 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 two states of folding and overlapping and flattening. In the absence of external force, the V-shaped elastic sheet as the upper fixing sheet 1 is in a folded state with the vertically extending fold as the center plane. When the V-shaped elastic sheet 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 conducive to the part of the umbrella surface with the upper fixing sheet attached to it automatically folding 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 sheet 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 fixedly mounted on the two ends of the torsion spring, the C-shaped elastic buckle and the V-shaped elastic buckle for elastic swinging, respectively, so that the upper fixing sheet 1 can automatically swing and fold elastically after the umbrella is folded. In addition, two sheets arranged at intervals or a flexible crease is formed in the middle of the two sheets, and 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 sheet may not have the elastic swing and folding function, and it only supports 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 sheet, which is more conducive to the umbrella surface being folded and flat in an orderly manner according to rules. The above structures are equivalent replacement structures that can be easily thought of by technicians in this field based on the present application, and all belong to the protection scope of the present application.

[0035] The upper fixing plate 1 is provided with a U-shaped notch 11 extending vertically, and 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 less than the vertical length of the upper fixing plate 1. When in use, the setting of the U-shaped notch 11 can reduce the length of the middle bend, thereby avoiding the influence on the vertical fold 53 of the umbrella surface 5, and making the umbrella surface 5 fold and fit tightly after the folding umbrella is folded as much as possible, so that the diameter of the umbrella after bundling is as small as possible, and the depth of the U-shaped notch 11 can be designed according to actual conditions, ensuring that it has sufficient elastic force so that the two side walls of the upper fixing plate 1 can pull the umbrella surface 5 to fold flat, and at the same time reduce the thickness of the folding root of the umbrella surface 5. When the upper fixing plate does not have elastic rebound to realize the automatic folding function, the upper fixing plate can also be two separate pieces, and a gap extending in the vertical direction is formed between the two, and this gap serves as the fold extending in the vertical direction 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, and 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 two states of folding and overlapping and flattening, 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 pieces or linear materials with a certain hardness in cooperation with a torsion spring, a C-shaped elastic buckle and a V-shaped elastic buckle. The two narrow pieces or linear materials are respectively fixed and mounted on the two ends of the torsion spring, the C-shaped elastic buckle and the V-shaped elastic buckle for elastic swinging, so that the lower fixing plate can be automatically elastically swung and folded after the umbrella is folded. In addition, the V-shaped elastic strip can also be formed by forming a flexible fold or an interval between two narrow pieces or two wires, and the two narrow pieces or wires are fixedly connected to the two ends of the spring or elastic rope, and the two narrow pieces or wires are pulled by the spring or elastic rope to swing and fold relative to each other. Such structures are equivalent replacement structures that can be easily thought of by technicians in this field based on the present application, and they all belong to the protection scope of the present application.

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

[0039] The lower fixing plate also includes a support plate 3, two support plates 3 are distributed on both sides of the other end of the V-shaped elastic strip 2, and the two support plates 3 can be folded with the other end of the V-shaped elastic strip 2 as a 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 by external force. The umbrella surface 5 on both sides of the V-shaped elastic strip 2 can be supported by the support plates 3, so that the umbrella surface 5 of the outer circle can maintain a flat folded state 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, which all belong to the protection scope of this application.

[0040] The two support sheets 3 form an integrally formed V-shaped elastic sheet, and the two support sheets 3 can relatively elastically swing along the vertically extending folds to change the angle between the two, and the folding direction of the support sheet 3 is opposite to the folding direction of the upper fixed sheet 1, and the other end of the V-shaped elastic strip 2 is fixedly connected with the folding part extending vertically on the support sheet 3 of the V-shaped elastic sheet structure by an integral forming method or a split assembly method. The support sheet 3 of this structure not only has a supporting function for the outer circle umbrella surface 5, but also has a function of driving the outer circle umbrella surface 5 to fold automatically, which can further improve the folding flatness of the umbrella surface 5 after the folding umbrella is folded. This structure makes the folding of multi-fold umbrellas such as three-fold umbrellas, four-fold umbrellas, and five-fold umbrellas smoother and more compact, and avoids the upper fixed sheet 1 elastically folding when the umbrella is folded. The force of pulling the outer circle umbrella surface 5 to fold synchronously is insufficient, resulting in the outer circle umbrella surface 5 not being flat enough.

[0041] The two support sheets 3 are respectively arranged on the two lateral sides of the other end of the V-shaped elastic strip 2, and the two support sheets 3 are arranged at intervals on the two lateral sides of the other end of the V-shaped elastic strip 2, or the two support sheets 3 are connected to the two lateral sides of the other end of the V-shaped elastic strip 2 through a flexible structure. The support sheets 3 of this structure mainly support the umbrella surface 5, so that the outer circle of the umbrella surface 5 on the umbrella surface 5 remains flat after the umbrella is folded, and the two support sheets 3 can also be elastically folded according to torsion springs, V-shaped buckles, C-shaped buckles, tension springs, elastic ropes, etc.

[0042] The upper fixing plate 1 and the lower fixing plate are provided with an adhesive layer or a welding agent layer on the same side surface, and a release film 4 is pasted on the surface of the adhesive layer or the welding agent layer. The above structure allows the folding umbrella quick-closing assembly to be packaged and sold separately. When in use, it is only necessary to tear off the release film 4 and paste it flat on the surface of the umbrella 5 of an ordinary folding umbrella. The folding umbrella quick-closing assembly and the umbrella 5 can be directly pasted and fixed by the adhesive layer, or fixed by welding with the welding agent layer, or fixed by other methods.

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

[0044] It is best for the upper fixing plate 1 to cover the second circle 52 area of ​​the folding umbrella as much as possible. A gap is formed between adjacent upper fixing plates 1 that is opposite to the ribs 6 on the umbrella surface 5. The vertical fold 53 in the middle of the upper fixing plate 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 transverse edge of the upper fixing plate 1 and the transverse 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 folds, and at the same time ensure that the umbrella surface 5 is flat after folding. The lower fixing plate 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 plate is aligned with the vertical fold 53 in the middle of the adjacent ribs 6 of the first circle 51 on the umbrella surface 5. The supporting plate 3 of the lower fixing plate 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 detailed descriptions 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, which shall fall within the protection scope of the present invention.
