When the umbrella 11 is stored in the case 101, it covers the other part of the umbrella 11 that cannot be stored in the case 101. The other end of the storage bag 201 is open and is used to take the folded umbrella 11 in and out.

Description

[Technical Field]

[0001] The present disclosure relates to a folding umbrella. [Background technology]

[0002] 2. Description of the Related Art Folding umbrellas (sometimes abbreviated as "umbrellas" as appropriate throughout this specification) that can be stored in a case are known.

[0003] For example, the folding umbrella disclosed in Patent Document 1 has an external shape similar to a beverage bottle. The cylindrical part is the case, and the part at one end of the case that narrows in diameter and resembles a spout is the umbrella handle (see [Perspective View] in Document 1). When the handle is pulled out of the case, the umbrella, which has been stored in a folded state, is pulled out, and the umbrella fabric can be opened and used as an umbrella (see [Reference Figures 1] to [Reference Figure 3] in Document 1).

[0004] This type of folding umbrella is also described, for example, in Patent Document 2. This folding umbrella has a cylindrical case (storage case (13)), and a member attached to the opening serves as the umbrella handle (grip handle (14)) (see paragraphs 0014-0016 and figures 1-4 of Patent Document 2). When the handle is pulled out of the case, the umbrella (folding umbrella body 12), which has been stored in a folded state, is pulled out, and the umbrella fabric (umbrella cloth (16)) can be opened and used as an umbrella.

[0005] The folding umbrella disclosed in Patent Document 3 differs from Patent Documents 1 and 2 in that the case itself serves as the umbrella handle (grip handle (1)). This folding umbrella has a central pole (fixed shaft (5)) fixed to the bottom of the cylindrical case, and the umbrella can be stored in the case in a folded state by pushing the movable shaft (4) into the fixed shaft (5).

[0006] The ferrule of the umbrella (2) is used as a lid for the case (see Reference 3, page 2, lines 7-20, Figures 1-4).

[0007] The folding umbrella described in Patent Document 4 has the same structure as that of Patent Document 3. The difference is that the case has a sliding double structure (rotating handle part (22) and sliding handle part (23)), and when used as an umbrella handle, the sliding handle part (23) is slid to overlap the rotating handle part (22). [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Design Registration No. 1338845 [Patent Document 2] Utility Model Registration No. 3191401 [Patent Document 3] Japanese Utility Model Application Publication No. 51-7156 [Patent Document 4] Utility Model Registration No. 3232727 Summary of the Invention [Problem to be solved by the invention]

[0009] The folding umbrellas described in Patent Documents 1 and 2 require the user to carry the case when using the umbrella. Of course, it is conceivable that the user may leave the case at home and continue to use the folding umbrella in an open state, but this would halve the role of the folding umbrella and is not realistic.

[0010] In contrast, in the case of the folding umbrella described in Patent Document 3, the case is used as the umbrella handle, freeing the user from the hassle of having to carry a case that has lost its intended use.

[0011] However, even when folded, the case must be long enough to store the umbrella, which makes it long. For this reason, when used as an umbrella handle, it tends to be too long (see Figure 1 of Patent Document 3), which makes it difficult to use from both a physical perspective of ease of handling and a psychological perspective of visual discomfort.

[0012] Improvement is desired.

[0013] In the folding umbrella described in Patent Document 4, when the umbrella is in use, the sliding handle portion (23) which is the case overlaps with the rotating handle portion (22), so that the overall length of the case can be shortened.

[0014] However, this increases the diameter of the case used as the handle, making it difficult to grip, and the drawbacks to usability cannot be eliminated, both from the physical aspect of ease of handling and from the psychological aspect of visual discomfort.

[0015] Moreover, the folding umbrella described in Patent Document 4 has a double structure of a rotating handle portion (22) and a sliding handle portion (23), which also leads to a complicated structure.

[0016] Improvement is desired.

[0017] The object of the present disclosure is to obtain a folding umbrella that is comfortable to use. [Means for solving the problem]

[0018] One aspect of a folding umbrella comprises a foldable umbrella, a case that is open on one side and has the tip of the umbrella's center pole fixed to the inner bottom, and that stores part of the umbrella in a folded state, and a flexible umbrella bag that is attached to the opening of the case and that covers the other part of the umbrella that is not stored in the case when the umbrella is stored in the case, and the case is used as a handle for the umbrella. [Effects of the Invention]

[0019] A folding umbrella with a good usability can be obtained. [Brief explanation of the drawings]

Variations

[0022] 1. Appearance The present embodiment will be described with reference to the drawings. In this embodiment, the case 101 and the bag 201 are integrated together, and a folding umbrella 11 can be stored inside the case 101 and the bag 201.

[0023] (1) External appearance As shown in FIGS. 1 to 8, the case 101 has a cylindrical shape with an opening 111 on one side, and a bag 201 is attached to the opening 111 (see FIG. 7).

[0024] As shown in Figure 9, the case 101 also serves as the handle 32 of the umbrella 11, and is used as the handle 32 when the umbrella 11 is in use. The case 101 fixes the tip of the shaft 31 of the umbrella 11 to the inner bottom, and stores part of the umbrella 11 in a folded state (see Figure 8).

[0025] Case 101 is made of, for example, resin, and is given a shape in which the diameter increases toward opening 111. The end of case 101 opposite opening 111 has a curved surface shape.

[0026] The common bag 201 is a bag-like structure with an open bottom made by sewing a flexible material, such as cloth, and is attached to the opening 111 of the case 101. When the umbrella 11 is folded and stored in the case 101, the common bag 201 covers the other part of the umbrella 11 that cannot be stored in the case 101.

[0027] The bag 201 has at one end an open fixed end 211 that is attached and fixed to the case 101, and at the other end an open end 212 that is open for inserting and removing the umbrella 11. The open end 212 is provided with a slit 213 that widens the opening area to make it easier to insert and remove the folded umbrella 11.

[0028] A drawstring 214 is embedded around the opening end 212 of the bag 201. The drawstring 214 is passed through a space created at the edge of the opening end 212 by folding the fabric inward at the opening end 212 and sewing it in. Both ends of this space are open at the slits 213. The drawstring 214 passed through the space has both ends exposed to the outside at the slits 213. Both ends of the drawstring 214 are joined to end rings 321, which will be described later, and form an endless shape (hereinafter referred to as "endless shape").

[0029] The endless drawstring 214 can be held by hand and the cloth located at the opening end 212 can be squeezed up, thereby narrowing the opening of the opening end 212.

[0030] As shown in Figures 1 to 5(A) and (B), the drawstring 214 is provided with a fastener 301 for fastening the narrowed open end 212. The fastener 301 has a combined structure of a slider 311 slidably attached to the drawstring 214 and an end ring 321 fixed to the end of the drawstring 214.

[0031] The slider 311 is a cylindrical member made of resin, for example, and has two through holes 312 on its side surface. These through holes 312 each penetrate the side surface of the slider 311 from a first position to a second position, and are open at the first and second positions. Because of its endless shape, the drawstring 214, which branches into two and is exposed from the slit 213, is passed through each of the two through holes 312, maintaining its endless shape.

[0032] The inner diameter of the through-hole 312 is set to a degree that generates a certain amount of friction between it and the drawstring 214. Here, "a certain amount of size" means that when the drawstring 214 has tightened the opening of the opening end 212 of the bag 201 and the slider 311 is slid up to the opening end 212, the slider 311 does not slide easily relative to the drawstring 214 and can function as a stopper.

[0033] As described above, the end ring 321 is embedded around the open end 212 of the bag 201, branches into two branches from the slit 213, and is exposed to the outside. Each end joins the ends of the drawstring 214 that is passed through the through-holes 312 of the slider 311, giving the drawstring 214 an endless shape. The end ring 321 has a ring shape with a portion of its circumference missing. The size of the end ring 321 is determined so that it can be hooked onto a finger.

[0034] A coupling portion 313 is provided on the back side of the slider 311 (see FIGS. 2, 3(B), 4(A)(B), and 5(A)(B)). The coupling portion 313 has a shape that allows the end ring 321 to be fitted in and maintained in that state. More specifically, the outer edge of the back side of the slider 311 has a diameter slightly larger than the inner diameter of the end ring 321, and the outer periphery of the slider 311 has a dimension that is equal to or smaller than the inner diameter of the end ring 321. This allows the coupling portion 313 to change from a state in which the end ring 321 is detached (see FIG. 5(A)) to a state in which the end ring 321 is fitted in (see FIG. 5(B)).

[0035] 5(B), when the end ring 321 is fitted into the connecting portion 313 of the slider 311, the drawstring 214, which maintains an endless shape, forms a loop (hereinafter referred to as a "loop shape"). At this time, the two drawstrings 214 that have passed through the two through-holes 312 of the slider 311 connect the slider 311 and the end ring 321 in a loop shape.

[0036] In this embodiment, the state in which the end ring 321 is fitted into the connecting portion 313 of the slider 311 is called a "loop connection." The state in which the two drawstrings 214 connect the slider 311 and the end ring 321 in a loop shape is called a "loop."

[0037] The end ring 321 fitted into the connecting portion 313 of the slider 311 catches on the outer edge of the back surface of the slider 311, maintaining the loop connection. The fitting force of the slider 311 to the connecting portion 313, i.e., the connecting force of the loop connection, is set to a strength that can maintain the folding umbrella in that state when the umbrella is passed through the loop and hooked onto a bag strap or harness (neither of which are shown).

[0038] On the other hand, the connecting strength of the loop connection is set to such an extent that the two can be easily separated by manually turning over the slider 311 from the connecting portion 313.

[0039] (2) Structure for attaching the bag to the case 6, a fixing ring 131 is attached to the opening 111 of the case 101. The fixing ring 131 has the same diameter as the case 101.

[0040] As shown in Figure 7, the end of case 101 on the opening 111 side is stepped, with a diameter reduced by the thickness of fixing ring 131. Fixing ring 131 is detachably attached to this stepped portion with a reduced diameter. An outer peripheral ridge 112 is provided along the circumferential direction on the outer peripheral surface of the stepped portion of case 101, and an inner peripheral groove 132 is provided along the circumferential direction on the inner peripheral surface of fixing ring 131. Fixing ring 131 is fixed to case 101 by fitting inner peripheral groove 132 into outer peripheral ridge 112.

[0041] At this time, the fixing force of fixing ring 131 to case 101 is set to a degree that the two do not easily separate without using, for example, a sharp tool.

[0042] The common bag 201 is attached to the case 101 by positioning the fixed end 211 at the stepped portion of the case 101 where the diameter is reduced, inserting the fixing ring 131 through the open end 212 provided with the fastener 301, and fitting the fixing ring 131 into the stepped portion. At this time, the fixed end 211 of the common bag 201 is sandwiched between the case 101 and the fixing ring 131, and is fixed so that it will not easily come off.

[0043] (3) Inside the case As shown in FIG. 8, the inside of the case 101 is hollow and can accommodate the umbrella 11 in a folded state.

[0044] A rib 121 having a cross-shaped horizontal cross section is provided on the inner bottom of the case 101, and a rod support fitting 122 is embedded in the center of the cross. The rod support fitting 122 has an insertion hole 123 extending vertically. The insertion hole 123 receives the tip of the rod 31 of the umbrella 11 and holds the rod 31 in place.

[0045] As one example, an adhesive can be used to fix the center rod support fitting 122 to the case 101. As another example, if the case 101 is made of resin, the center rod support fitting 122 may be insert-molded into the case 101.

[0046] As an example, adhesive can be used to secure the center pole 31 of the umbrella 11 to the insertion hole 123 of the center pole support bracket 122. As another example, a method called press-fitting can be used. A combination of press-fitting and adhesive can also be used. As yet another example, a female thread can be provided in the insertion hole 123 and a male thread can be provided in the center pole 31 of the umbrella 11, and they can be fastened together with screws. A combination of screw-fastening and adhesive can also be used.

[0047] 2. Umbrella (1) Overview As shown in Figures 9 and 10, the umbrella 11 has a skeletal structure 12 in which the ribs 51 are arranged to open and close radially relative to the center rod 31. The ribs 51 are divided into three parts: a base rib 51A, a middle rib 51B, and a tip rib 51C. The base rib 51A, the middle rib 51B, and the tip rib 51C are foldable and open radially. This allows the umbrella 11 to be folded in three stages.

[0048] 11 and 12, the umbrella 11 is also provided with ribs 52. The ribs 52 are connected to the base ribs 51A and play a role in the opening and closing movement of the ribs 51.

[0049] An umbrella material 71 is attached to the ribs 51 (main rib 51A, middle rib 51B, tip rib 51C). Details of the umbrella material 71 will be described later.

[0050] The skeletal structure 12 has five sets of ribs 51 (main rib 51A, middle rib 51B, tip rib 51C) and support ribs 52, and the ribs 53 made up of these ribs 51 and support ribs 52 are divided into five parts. The spaces between adjacent ribs 53 are spaces 54. The spaces 54 are also divided into five parts.

[0051] (2) Center rod As shown in Figures 9 and 10, the center rod 31 is a pipe-shaped metal member with a handle 32 (case 101) at one end that can be held by the user and a corresponding end that is connected to the ribs 51. The center rod 31 is divided into three tubes in a nested arrangement: a large tube 31a, a medium tube 31b, and a small tube 31c. The large tube 31a is the tube located on the handle 32 side and has the largest diameter. The diameters of the tubes decrease in order from the middle tube 31b to the small tube 31c that connects to the base rib 51A. The large tube 31b is slidably housed in the large tube 31a, and the small tube 31c is slidably housed in the medium tube 31b, forming a nested structure.

[0052] (3) Opening and closing structure As shown in Figures 10 to 12, the center rod 31 has a top roller 33 at the end of the small tube 31c, and the main ribs 51A are rotatably attached to the top roller 33. The five main ribs 51A rotate from a position roughly parallel to the center rod 31 to a position nearly perpendicular to the center rod 31, thereby opening and closing the umbrella 11. The opening and closing of the main ribs 51A is achieved by the bottom roller 34 and the five support ribs 52.

[0053] The lower pulley 34 is a pipe-shaped member slidably attached to the outer periphery of the small tube 31c. The ribs 52 are rotatably attached at one end to the lower pulley 34 and at the opposite end to a position midway along the main rib 51A. When the lower pulley 34 is slid along the small tube 31c toward the upper pulley 33, the ribs 52 push the main rib 51A in the opening direction, thereby promoting the opening of the umbrella 11. Conversely, when the lower pulley 34 is slid along the small tube 31c toward the handle 32, the ribs 52 pull the main rib 51A in the closing direction, thereby promoting the closing of the umbrella 11.

[0054] The small tube 31c of the center rod 31 is provided with a spring 35 that is retractable and biased in a protruding direction. The runner 34 climbs over the spring 35 as it slides until the five base ribs 51A are in the open position, and after climbing over the spring 35, the spring 35 restricts its movement toward the handle 32. This keeps the umbrella 11 open. To close the umbrella 11 in this state, the spring 35 is pushed in, releasing the spring 35 from restricting the movement of the runner 34. With the restriction on movement released, the runner 34 slides toward the handle 32, allowing the umbrella 11 to close.

[0055] (4) Folding structure

[0056] (a) Folding an umbrella As shown in Figure 11, when umbrella 11 is opened, base rib 51A rotates away from center rod 31, middle rib 51B rotates away from base rib 51A, and tip rib 51C rotates away from middle rib 51B. As a result, base rib 51A and middle rib 51B are positioned almost on the same line, and tip rib 51C is positioned at an obtuse angle from that line, and umbrella 11 is opened (see Figure 10).

[0057] In the process of closing the umbrella 11, the base rib 51A rotates toward the handle 32 to approach the center rod 31, the middle rib 51B rotates in the opposite direction to the handle 32 to approach the base rib 51A, and the tip rib 51C rotates toward the handle 32 to approach the middle rib 51B. This causes the umbrella 11 to fold (see Figure 12).

[0058] As shown in Figure 12, when the umbrella 11 is closed, the ribs 51, consisting of the base rib 51A, middle rib 51B, and tip rib 51C, are approximately parallel to the center rod 31, and the umbrella 11 is in a folded state. In Figure 12, the ribs 53 are drawn slightly open to avoid the three ribs 51 and the support ribs 52 overlapping and becoming invisible, but in reality, the ribs 53 are closed until they are approximately parallel to the center rod 31.

[0059] (b) Interlocking mechanism The umbrella 11 of this embodiment is equipped with an interlocking mechanism IM as a structure that realizes the folding operation of the umbrella 11. The interlocking mechanism IM is linked to the opening and closing operation of sliding the lower wheel 34 relative to the center rod 31, and opens and closes each of the five ribs 53 branching out in the radial direction so that they can be folded radially.

[0060] The interlocking mechanism IM will be described with reference to FIGS.

[0061] A receiving dowel 55 is provided at the connection between the main rib 51A and the support rib 52, a main dowel 56 is provided at the connection between the main rib 51A and the middle rib 51B, and a tip dowel 57 is provided at the connection between the middle rib 51B and the tip rib 51C.

[0062] The receiving dowel 55 has a connected body 55a provided in the middle part of the original rib 51A and a connecting body 55b provided at the tip part of the bridge rib 52. The connecting body 55b is connected to the connected body 55a so as to be rotatable around an axis perpendicular to the axial direction of the center rod 31, thereby rotatably connecting the original rib 51A and the bridge rib 52.

[0063] The base dowel 56 includes a connected body 56a provided at the rear end of the middle rib 51B and a connecting body 56b provided at the front end of the base rib 51A. The connecting body 56b is connected to the connected body 56a rotatably around an axis perpendicular to the axial direction of the center rod 31, thereby rotatably connecting the base rib 51A and the middle rib 51B.

[0064] The tip dowel 57 includes a connected body 57a provided at the rear end of the tip rib 51C and a connecting body 57b provided at the tip end of the middle rib 51B. The connecting body 57b is connected to the connected body 57a rotatably around an axis perpendicular to the axial direction of the center rod 31, thereby rotatably connecting the middle rib 51B and the tip rib 51C.

[0065] The receiving dowel 55 has a first hole A1 formed in the connecting body 55b. The base dowel 56 has a second hole A2 formed in the connected body 56a. The first hole A1 is formed at a position on the bridge rib 52 slightly closer to the base than the connecting position of the connecting body 55b to the connected body 55a. The second hole A2 is formed at the end of the intermediate rib 51B on the base side of the intermediate rib 51B, away from the connecting position of the connecting body 56b to the connected body 56a.

[0066] A spring 58 is stretched between the first hole A1 and the second hole A2. The spring 58 is a wire-like member made of a metal and having elasticity.

[0067] The base spring 58 rotates the middle rib 51B in response to the rotation of the base rib 51A. More specifically, when the base rib 51A is opened, the base spring 58 pulls the base portion of the middle rib 51B at the position of the second hole A2, causing the middle rib 51B to rotate in the opening direction. When the base rib 51A is closed, the base spring 58 pushes the base portion of the middle rib 51B at the position of the second hole A2, causing the middle rib 51B to rotate in the closing direction.

[0068] The base dowel 56 has a third hole A3 formed in the connecting body 56b. The tip dowel 57 has a fourth hole A4 formed in the connected body 57a. The third hole A3 is formed in the base rib 51A, slightly closer to the base than the connecting position of the connecting body 56b to the connected body 56a. The fourth hole A4 is formed in the tip rib 51C, at the end of the base side of the tip rib 51C, away from the connecting position of the connecting body 57b to the connected body 57a.

[0069] A tip spring 59 is hung between the third hole A3 and the fourth hole A4. A hook 60 is attached to the center of the middle rib 51B, slightly toward the tip. The tip spring 59 is an elastic metal wire member that is hooked onto the hook 60 and held in place.

[0070] The tip spring 59 rotates the tip rib 51C in response to the rotation of the base rib 51A. More specifically, when the base rib 51A is opened, the tip spring 59 pulls the base of the tip rib 51C at the position of the fourth hole A4, causing the tip rib 51C to rotate in the opening direction. When the base rib 51A is closed, the tip spring 59 pushes the base of the tip rib 51C at the position of the fourth hole A4, causing the tip rib 51C to rotate in the closing direction.

[0071] (5) Wheel As shown in Figure 13, the runner 34 is a pipe-shaped member through which the center rod 31 passes. The runner 34 has three functions.

[0072] The first role is to rotatably hold the ribs 52. This role is played by the wheel portion 36 provided in the axial center of the lower wheel 34.

[0073] The turntable 36 has lower rib grooves 37 for inserting the base portions of the ribs 52, and lower wire grooves 39 for inserting lower wires 38 that pass through the base portions of the ribs 52 inserted into the lower rib grooves 37. The ribs 53 are divided into five sections, and five ribs 52 are provided, so there are five lower rib grooves 37. The five ribs 52 are inserted into the lower rib grooves 37, bundled together by the lower wires 38, and rotatably held in place.

[0074] The second role is to realize coupling and uncoupling by catching on the stopper 35. The lower wheel 34 has a stopper 40 that extends downward (toward the handle 32) from the wheel part 36. The second role is played by a stopper hole and an operation button 41 (not shown) provided in the stopper 40.

[0075] 13, when the runner 34 is slid upward (toward the upper wheel 33), the runner 34 passes over the stopper 35. At this time, the stopper 35 protrudes outward from a stopper hole provided in the stopper 40 and catches on the runner 34, restricting the sliding movement of the runner 34 downward (toward the handle 32).

[0076] In this state, the operation button 41 faces the lever 35. The operation button 41 is a member with elasticity that allows it to return to its initial position even when pressed. When the operation button 41 is pressed, the lever 35 is pushed into the center rod 31, and the connection with the runner 34 that was caused by the catch is released. With the connection with the lever 35 released, the runner 34 becomes able to slide downward (towards the handle 32).

[0077] The third role is to maintain a gap between the lower pulley 34 and the upper pulley 33 when the umbrella 11 is open, and to restrict the upper pulley 34 from sliding upward. This role is played by the spacer 42, which extends upward (toward the upper pulley 33) from the pulley portion 36. When the lower pulley 34 is restricted from sliding downward (toward the handle 32) by the latch 35, the spacer 42 faces the upper pulley 33 with a slight amount of play. This maintains a gap between the lower pulley 34 and the upper pulley 33, and restricts the upper pulley 34 from sliding upward.

[0078] (6) Wheel Throwing As shown in FIG. 13, the upper wheel 33 is fixed to the upper end of the center rod 31 and rotatably holds the base rib 51A.

[0079] The upper wheel 33 has an upper rib groove 43 for inserting the base portion of the main rib 51A, and an upper wire groove 45 for inserting an upper wire 44 that passes through the base portion of the main rib 51A inserted into the upper rib groove 43. The rib 53 is divided into five parts, and there are five main ribs 51A, so there are also five upper rib grooves 43. The five main ribs 51A are inserted into the upper rib grooves 43, bundled with the upper wire 44, and rotatably held.

[0080] (7) Materials and shapes of each part Of the ribs 53, the base rib 51A and the support ribs 52 are made of, for example, metal. The base rib 51A and the support ribs 52 have, for example, a flat plate-like cross section.

[0081] Of the ribs 53, the middle rib 51B and the tip rib 51C are made of resin or plastic, such as fiber-reinforced resin or fiber-reinforced plastic, and the middle rib 51B and the tip rib 51C have, for example, a round bar shape.

[0082] The receiving dowel 55, the base dowel 56, and the tip dowel 57 are molded from resin or plastic such as fiber reinforced resin or fiber reinforced plastic.

[0083] The upper wheel 33 and the lower wheel 34 are also molded from resin or plastic, such as fiber-reinforced resin or fiber-reinforced plastic.

[0084] (8) Umbrella fabric The material of the umbrella fabric 71 is, for example, nylon or polyester. More specifically, it is 100% nylon or 100% polyester.

[0085] The umbrella fabric 71 is attached to the ribs 51. The center part of the umbrella fabric 71 is fixed by being sandwiched between the top wheel 33 and the ferrule 46, and the end part of the umbrella fabric 71 is fixed by being tied with thread or the like to the tip 61 provided at the end of the leading rib 51C. The other parts are also fixed to the ribs 51 by being tied with thread or the like.

[0086] A name band 72 is attached to the umbrella fabric 71. When the umbrella 11 is closed and folded, the name band 72 secures the closed and folded umbrella ribs 53 together with the umbrella fabric 71, keeping it in the folded state.

[0087] 3. Effects (1) Using and storing umbrellas To use the umbrella 11, the following steps are performed.

[0088] As shown in FIG. 14, the fastener 301 is released to open the opening end 212 of the bag 201, and the bag 201 is turned up towards the case 101.

[0089] As shown in Figure 15, the center rod 31 is extended, that is, the center tube 31b and the small tube 31c are pulled out from the large tube 31a.

[0090] As shown in Figure 16, the name band 72 is released to free the skeletal structure 12, and the umbrella 11 is unfolded. To unfold the umbrella 11, the lower roller 34 is slid toward the upper roller 33 (see Figures 11 and 12). This causes the base rib 51A to be pushed by the support ribs 52 and rotate outward away from the center rod 31. At this time, due to the action of the interlocking mechanism IM, the middle rib 51B rotates inward away from the base rib 51A, and the tip rib 51C rotates outward away from the middle rib 51B. This opens the umbrella 11.

[0091] Before and after, the umbrella bag 201 that had been turned up toward the case 101 is returned to its original position and stored by pushing it into the case 101 through the opening 111 (see FIG. 16). This causes the umbrella 11 to be pulled out, and the umbrella bag 201 is stored in the empty case 101. At this time, the drawstring 214 and possibly the fastener 301 are also stored in the case 101.

[0092] To store the umbrella 11 again, the following steps are performed.

[0093] Closing the umbrella 11. To close the umbrella 11, slide the lower roller 34 away from the upper roller 33 (see Figures 11 and 12). This causes the base rib 51A to be pulled by the support ribs 52 and rotate inward toward the center rod 31. At this time, the interlocking mechanism IM causes the middle rib 51B to rotate outward toward the base rib 51A, and the tip rib 51C to rotate inward toward the middle rib 51B. As a result, the ribs 51 (base rib 51A, middle rib 51B, tip rib 51C) and support ribs 52 that make up the umbrella ribs 53 become approximately parallel to the center rod 31, and the umbrella 11 is folded.

[0094] As shown in FIG. 16, the folded umbrella 11 is gathered by rolling up the umbrella fabric 71 and fastening it with a name band 72 (see FIG. 15).

[0095] Before and after, the bag 201 stored in the case 101 is pulled out and turned up again toward the case 101 (see FIG. 15).

[0096] As shown in Figure 14, the center rod 31 is contracted so that the middle tube 31b and the small tube 31c overlap the large tube 31a.

[0097] The bag 201 that was turned up toward the case 101 is returned to its original position, and the remaining part of the umbrella 11 that cannot be stored in the case 101 is covered with the bag 201. The opening end 212 of the bag 201 is tightened with the drawstring 214, and the slider 311 is slid and fastened with the fastener 301, completing the process of storing the umbrella 11 (see Figures 1 to 5(A)).

[0098] (2) Basic effects According to this embodiment, the case 101 and the flexible bag 201 are integrated to store the umbrella 11, and the case 101 is used as the handle 32 of the umbrella 11.

[0099] Therefore, a case separate from the umbrella 11 is no longer necessary, and the user can be relieved from the hassle of having to carry such a case.

[0100] Because the case 101 can be used as the handle 32 of the umbrella 11, it is possible to prevent the case 101 from becoming longer or thicker. This improves the usability when using the case 101 as the handle 32, both from the physical aspect of ease of handling and from the psychological aspect of visual discomfort.

[0101] (3) Case shape (3-1) The case 101 has a cylindrical shape, and the diameter increases toward the opening 111 .

[0102] Therefore, the umbrella 11 fits comfortably in the hand when in use, providing a user with a good usability.

[0103] Another technical significance of the diameter increasing toward the opening 111 is that it makes it easier to store the umbrella bag 201 and other items when using the umbrella 11, thereby improving workability.

[0104] (3-2) The end of the case 101 opposite to the opening 111 is curved.

[0105] Therefore, when wearing the folding umbrella, it feels softer against the human body, so that even if the folding umbrella hits the user or someone else, for example, when riding on a crowded train, the user will not feel uncomfortable.

[0106] (4) Handling of the bag when not in use The bag 201 that covers the umbrella 11 when folded and stores the umbrella 11 together with the case 101 is made of a flexible material such as cloth, so that when the umbrella 11 is not in use, it can be stored in the empty case 101.

[0107] Therefore, the presence of the bag 201 does not impair the feeling of use of the umbrella 11, and a comfortable feeling of use can be provided to the user.

[0108] The drawstring 214 or fastener 301 is also stored in the case 101 together with the bag 201, which further improves comfort during use.

[0109] (5) Attaching the bag to the case According to this embodiment, the common bag 201 is attached to the case 101 by a simple structure in which the fixing ring 131 is fitted into the case 101.

[0110] Therefore, the structure can be simplified.

[0111] This also facilitates the attachment of the bag 201 to the case 101.

[0112] (6) Case material Since the case 101 is made of resin, the overall weight can be reduced.

[0113] (7) Fasteners The fastener 301 not only serves to keep the opening end 212 of the bag 201 closed, but also functions like a hook by fitting an end ring 321 into the connecting portion 313 to form a loop connection, and passing the loop through the bag strap or harness to hang the folding umbrella.

[0114] Therefore, it is possible to provide a variety of ways of using the device to users.

[0115] 4. Variations Various modifications and variations are possible in implementation.

[0116] In the above embodiment, the materials and shapes of the various parts are mentioned, but the present invention is not limited to these materials and shapes, and other materials and shapes may be used.

[0117] For example, the case 101 does not necessarily have to be made of resin, and may be made of metal such as aluminum or brass.

[0118] The bag 201 is not limited to being made of cloth either, and may be made of, for example, vinyl or other materials.

[0119] In this embodiment, a rod support bracket 122 is provided as a means for fixing the rod 31 of the umbrella 11 to the case 101, but if the case 101 is made of a hard material such as metal, it is not necessarily necessary to provide an independent part such as the rod support bracket 122. An insertion hole 123 may be provided directly in the case.

[0120] In this embodiment, the number of divisions and folds of the ribs 53 are shown, but these are merely examples. Needless to say, other numbers of divisions and folds may be used in practice.

[0121] Any other variations or modifications are permitted. [Explanation of symbols]
