DETAILED DESCRIPTION OF THE INVENTION

[0018] [1] An embodiment of the present invention will be described with reference to the drawings.

[0019] All of the drawings relate to an umbrella bag U for a folding umbrella as an example of an embodiment of the present invention.

[0020] The umbrella pouch U comprises a tubular structure Ts having a tubular portion T and a pair of leaf spring bodies S of equal length for forming a spring mouthpiece portion.

[0021] (1) Cylindrical part

[0022] The tubular portion T of this umbrella bag U is made mainly of a water-repellent fabric material that is a flexible sheet-like material, and has a vertically long rectangular bag shape when viewed from the front.

[0023] One end in the longitudinal direction of the bag-shaped portion, which is the tubular portion T, is an openable / closable opening T1, and the other end is a closed portion.

[0024] The right long side and the bottom short side of the tubular portion T, which is a vertically long rectangular bag when viewed from the front, can be opened and closed by a linear fastener F.

[0025] When the linear fastener F is closed, the tubular portion T (bag-like portion) is formed into a bag-like shape with an opening T1 at one end, and by opening the linear fastener F, the tubular portion T (bag-like portion) can be opened in a substantially flat shape from the opening T1 at one end in the longitudinal direction to the lower end, thereby deforming the tubular portion T. By closing the linear fastener F again, the tubular portion T (bag-like portion) can be restored to its original shape.

[0026] (2) A spring mouthpiece and a retaining hole made of a plate spring

[0027] (2-1) The opening T1 at the upper end of the tubular portion T is made up of a retaining hole forming portion P sewn to the opening end, which is the upper end of the main bag-shaped portion T2 that constitutes the portion other than the opening T1.

[0028] The retaining hole forming portion P is sewn from a water-repellent cloth-like material and has a string-like shape with a retaining hole Pa formed therein in advance. The length of the retaining hole forming portion P is formed to be approximately one-sixth longer than the overall circumferential length (in the direction perpendicular to the cylindrical axis) of the upper end opening T1 of the main bag-shaped portion T2, with one end of the retaining hole Pa being a closed closed end P1 and the other end being an open insertion / removal opening P2. A tab P3 is provided on the outer circumferential side of the insertion / removal opening P2, protruding short in the circumferential direction.

[0029] The retaining hole forming portion P has a closed end P1 where the retaining hole Pa is closed, which is located at the right end of the front surface at the upper end of the main bag-shaped portion T2, and extends along the upper edge of the front surface of the main bag-shaped portion T2 to the left end, then around to the back side and from the left end of the back surface to the right end, so that the lower part of the retaining hole forming portion P and the upper end of the main bag-shaped portion T2 are sewn together so that the closed end P1 extends almost completely around the circumferential direction of the upper end opening T1 of the main bag-shaped portion T2.

[0030] Of the retaining hole forming portion P, about one-sixth of the portion on the insertion / removal opening P2 side of the retaining hole Pa constitutes an extension portion Pr that extends away from the tubular portion T (main bag-shaped portion T2) at the right end of the back surface. When the extension portion Pr is bent toward the front side of the retaining hole forming portion P, hook-and-loop fasteners V that can be joined and released to each other are provided on the inner surface portion of the opposing extension portion Pr and the outer surface portion of the retaining hole forming portion P.

[0031] (2-2) A pair of substantially identical (and therefore equal in length) stainless steel plate leaf springs S for forming the spring mouthpiece are removably housed in the retaining hole Pa. The length of each leaf spring S corresponds to half the circumference of the cylindrical portion T (in the direction perpendicular to the cylindrical axis).

[0032] (2-3) A pair of leaf spring bodies S accommodated in the retaining hole portion Pa are connected at one end of one leaf spring body S and one end of the other leaf spring body S by a hinge-like connecting portion Sh so that they can rotate relative to each other around a predetermined rotation axis, and the other ends of both leaf spring bodies S are both free ends S1.

[0033] (2-4) A pair of leaf springs S can be inserted into and removed from the retaining hole Pa in one direction through the insertion / removal opening P2 at the tip of the extension Pr, from the free end S1 of one leaf spring S, via the hinge-like connecting portion Sh of both leaf springs S, to the free end S1 of the other leaf spring S. The insertion direction and the removal direction are opposite. If the leaf spring S has a protrusion on either the front or back of the free end S1 or another position, the protrusion can be used to insert and remove the pair of leaf springs S from outside the retaining hole Pa.

[0034] When a pair of leaf springs S are inserted up to the closed end P1 of the retaining hole Pa, the free end S1 of one leaf spring S is located at the closed end P1, and the one leaf spring S is located at the front portion of the retaining hole Pa. The hinge-shaped connecting portion Sh is located at the left end of the retaining hole Pa. The other leaf spring S is located at the rear portion of the retaining hole Pa, and its free end S1 is located near the base end Pr1 of the extension portion Pr of the retaining hole-forming portion P, which is the right end of the rear side of the retaining hole Pa. Neither leaf spring S is present at the extension portion Pr of the retaining hole-forming portion P.

[0035] In this state, by bending the extension portion Pr toward the front side of the retaining hole forming portion P and joining the extension portion Pr to the front side of the retaining hole forming portion P with a hook-and-loop fastener V, the pair of leaf spring bodies S are prevented from slipping out of the insertion / removal opening portion P2 and being exposed to the outside, and the free ends S1 of the pair of leaf spring bodies S are held adjacent to each other (without connecting the free ends S1 to each other), and the pair of leaf spring bodies S can form a spring nozzle-shaped portion.

[0036] 3 and 4, the linear fastener F is opened to open the cylindrical portion T (bag-shaped portion) from an opening T1 at one end in the longitudinal direction to the middle portion in the longitudinal direction, making the cylindrical portion T (bag-shaped portion) substantially flat, and the retaining hole Pa is made linear or gently curved, allowing the pair of leaf springs S to be smoothly inserted and removed from the retaining hole Pa. The cylindrical portion T (bag-shaped portion) can be formed by closing the linear fastener F with the pair of leaf springs S housed in the retaining hole Pa.

[0037] (2-5) When a pair of leaf springs S constitute a spring nozzle-shaped portion as described above, as shown in FIG. 9, in a state where the pair of leaf springs S (while supported by fingers N) is not substantially subjected to external force, the corresponding surfaces of one leaf spring S and the other leaf spring S are maintained in a state where they sandwich the inner portions of the cloth-like material that constitutes the retaining hole Pa (along the front and back of the same plane), and the tubular portion T is maintained in a closed state at the opening T1 at one end of the tubular portion T. By clamping and pressing the hinge-like connecting portion Sh, which connects the pair of leaf springs, and the free ends S1 of both leaf springs S held adjacent to each other with fingers N in the longitudinal direction of the leaf springs S, as shown in FIG. 10, both leaf springs S can be bent outward from each other to open the opening T1 of the tubular portion T where the retaining hole Pa is located.

[0038] The pair of leaf spring bodies S can be removed from the insertion / removal opening P2 by releasing the connection between the extension portion Pr and the outer peripheral surface of the tubular portion T using the hook-and-loop fastener V and separating the extension portion Pr from the outer peripheral surface of the tubular portion T. The knob portion P3 can be used to release the connection between the extension portion Pr and the tubular portion T using the hook-and-loop fastener V.

[0039] By removing the pair of leaf spring bodies S from the retaining hole portion Pa, it is possible to, for example, wash or clean the tubular structural portion Ts or an item including the tubular structural portion Ts, or dry the inside or the entirety of the item, and then by inserting the pair of leaf spring bodies S through the retaining hole portion Pa to restore the tubular portion T (bag-shaped portion), the pair of leaf spring bodies S can be made to function as a spring nozzle-shaped portion, allowing the tubular structural portion Ts to be used.

[0040] (3) Umbrella bag

[0041] This umbrella bag U, including the retaining hole forming portion P, is water-repellent, allowing it to store an umbrella wet with rainwater and to maintain the functionality of the pair of leaf spring bodies S stored in the retaining hole portion Pa by preventing them from getting wet.In addition, approximately 80% of the area on one side of the inside, in the short direction toward the line zipper F, is provided with water-absorbing pile L, which can absorb as much moisture as possible that may accompany the items stored inside.

[0042] In addition, a hanging or detachable string C is attached to the part along the linear zipper F on one side of the umbrella bag U, so that it can be attached to or detached from a handbag or bag, worn over the shoulder, or hung in a suitable location.

[0043] The string C is a flat string that is provided on the front side of the tubular portion T (bag-shaped portion) slightly inside from the long side T3 having the linear fastener F, so as to extend substantially along the longitudinal axis of the tubular portion T.

[0044] The base end of the string C is bent so as to be approximately perpendicular to the longitudinal axis direction of the tubular portion T, and the bent end C1 is sewn to a portion near the long side T3 in the lower half of the longitudinal direction of the tubular portion T. A holding piece C2 protrudes from the middle of the string C so as to be approximately perpendicular to the longitudinal axis direction of the tubular portion T, and the tip of the holding piece C2 is sewn to a portion near the long side T3 in the upper half of the longitudinal direction of the tubular portion T. As a result, a loop portion along the long side T3 is formed by the portion near the long side T3 of the tubular portion T, the bent end C1 sewn to the portion near the long side T3, the tip of the holding piece C2, and the string C.

[0045] Additionally, a fixed portion C3, which is closer to the tip than the middle portion of the string C, is sewn to the vicinity of the opening T1 of the tubular portion T. The tip portion of the string C is a free end provided with one of the snap buttons B, and can form a loop portion by joining it to the other snap button B provided between the holding piece C2 and the fixed portion C3 of the string C.

[0046] Therefore, as shown in Figure 11, a hanging ring portion can be formed outside the vertical axis direction of the opening T1, and the bag can be hung at one point on the handle G1 of the bag G, or as shown in Figure 12, the loop portion along the long side T3 formed by the folded end C1, the tip of the holding piece C2, and the string C can be hung horizontally on the handle G1 of the bag G.

[0047] (4) A spring mouthpiece and a retaining hole formed of a spring hinge

[0048] As shown in Fig. 13, the spring hinge body H serving as the mouthpiece component has a pair of arms Ha and Hb made of synthetic resin that can rotate relative to each other around a hinge rotation axis, and an elastic biasing member K (kick spring) that elastically biases the pair of arms Ha and Hb. The pair of substantially identical spring hinge bodies constitutes the spring mouthpiece.

[0049] The distal end portions of the arm portions Ha and Hb are elongated plate-like portions having a constant width in the direction of the hinge-like rotation axis.

[0050] The arm portions Ha and Hb have, at their respective base ends, pivotal connecting portions Ha2 and Hb2 for connecting them so that they can pivot relative to each other around a hinge pivot axis, and the shaft portion Hs passes through the hinge-like pivot axis of the pivotal connecting portions Ha2 and Hb2.

[0051] (4-1) The opening I1 of the tubular portion I constituting the umbrella pouch U shown in Figure 14 is made up of a holding hole forming portion J. The holding hole Ja formed in the holding hole forming portion J is made up of a pair of semi-circular portions and extends approximately around the circumference of the tubular portion I. Each of the pair of semi-circular portions has an outer opening J1 in the center of the circumference.

[0052] (4-2) Each spring hinge body H can be removably held by the pair of arm portions Ha and Hb in the retaining hole portions Ja on both sides of both outer openings J1, with the pivot connecting portions Ha2 and Hb2, through which the shaft portion Hs passes, positioned at the outer opening J1 and with the hinge pivot axis aligned approximately in the axial direction of the cylindrical portion I. The pair of arm portions Ha and Hb can be attached to and detached from the retaining hole portions Ja on both sides of the outer opening J1, for example, by positioning the pair of arm portions Ha and Hb so that predetermined portions Ha1 and Hb1 form an angle of, for example, 20 to 40 degrees with each other, positioning both sides of the outer opening J1 in the retaining hole forming portion J in a position corresponding to that angle, and inserting and detaching the arm portions Ha and Hb into and from the retaining hole portions Ja on both sides.

[0053] The pair of arm portions Ha and Hb in each of the pair of spring hinge-like bodies have both ends which are the free ends of the pair of arm portions Ha and Hb, and when held in the retaining hole portion Ja, the two free ends of one spring hinge-like body H are adjacent to the two free ends of the other spring hinge-like body H, thereby forming a spring mouthpiece-like portion that can open and close the tubular portion I.

[0054] The pair of arm portions Ha·Hb of the spring hinge body H held in the holding hole portion Ja are as follows: As shown in FIG. 13(a), predetermined portions Ha1 and Hb1 of both arm portions Ha and Hb on the inner side relative to the tubular portion I (the side that closes the tubular portion I when the spring hinge-like body H closes the tubular portion I as a spring mouthpiece-like portion) are aligned along the front or back of the same plane (a plane parallel to the hinge-like rotation axis), thereby allowing the tubular portion I to be closed between the predetermined portions Ha1 and Hb1 of the other spring hinge-like body H that are aligned along the front or back of the same plane; As shown in Figure 13(b), the inner specific portions Ha1 and Hb1 of both arm-like portions Ha and Hb form an angle of less than 180 degrees with each other, so that they can rotate relative to each other between a state in which they can open the tubular portion I together with the other spring-hinge-like body H.

[0055] (4-3) The elastic biasing member K in each spring hinge-like body H elastically biases the pair of arm-like portions Ha and Hb held in the retaining hole portion Ja so that, when the predetermined portions Ha1 and Hb1 of the pair of arm-like portions Ha and Hb form an angle with each other of, for example, 50 degrees to 90 degrees or more and less than 180 degrees, thereby opening the tubular portion I, each predetermined portion Ha1 and Hb1 is able to close the tubular portion I along the same plane.

[0056] (4-4) When the spring mouth-shaped portion formed by both spring hinge-shaped bodies H is in a closed state, by clamping one adjacent free end of both spring hinge-shaped bodies H against the other adjacent free end as shown in Fig. 14, the pivotal connecting portions Ha2 and Hb2 of both spring hinge-shaped bodies H open outward toward each other, and the inner angles between the predetermined portions Ha1 and Hb1 of a pair of arm-shaped portions Ha and Hb of each spring hinge-shaped body H become smaller than 180 degrees, thereby opening the spring mouth-shaped portion and opening the opening I1 of the tubular portion I. By releasing the clamping pressure, the biasing force of each elastic biasing member K of both spring hinge-shaped bodies H closes the spring mouth-shaped portion so that the predetermined portions Ha1 and Hb1 are all along the same plane, and the tubular portion I returns to its closed state.

[0057] [2] The embodiments of the present invention will be further described, including embodiments other than those described above.

[0058] The cylindrical structure of the present invention has a cylindrical portion and a pair of elastically bendable mouthpiece constituents for constituting a spring mouthpiece.

[0059] (1) Cylindrical part

[0060] (1-1) The tubular portion of the present invention is mainly made of a flexible material. The tubular portion may be, for example, bag-shaped as a whole or may constitute a part of a bag-shaped body.

[0061] The tubular portion can change shape between a state in which the inner surface portion of at least approximately half the circumference of the openable portion (e.g., the front portion) and the inner surface portion of the remaining approximately half the circumference (e.g., the back portion) are joined together to be closed, and a state in which the two inner surface portions are open to each other.

[0062] The flexible material that mainly constitutes the tubular portion may be a cloth-like material such as various woven fabrics or other flexible sheet-like materials.

[0063] (1-2) One end of the cylindrical portion (one end in the axial direction of the cylindrical portion) is an opening. The other end of the cylindrical portion can be, for example, a closed portion, an opening, or a portion connected to another structure.

[0064] (2) Retaining hole in the cylindrical part

[0065] The cylindrical portion has a holding hole portion at the opening at the one end or at another position along the circumferential direction of the cylindrical portion.

[0066] The retaining hole portion can be, for example, one that extends almost completely around the circumference of the cylindrical portion, one that extends almost completely around the circumference of the cylindrical portion with one end extending (for example, extending about one-sixth of the circumference), or one that consists of a pair of semi-circular portions.

[0067] For example, the retaining hole may be provided in a predetermined approximate half-circumferential portion and in the remaining approximate half-circumferential portion, and the retaining hole may be continuous across the predetermined approximate half-circumferential portion and the remaining approximate half-circumferential portion or divided into two or more portions, or may be continuous across the predetermined approximate half-circumferential portion and the remaining approximate half-circumferential portion or divided into two or more portions.

[0068] The retaining hole portion can be formed, for example, by attaching a retaining hole forming portion made of a flexible material or the like to a required position in the tubular portion, either non-detachably (by sewing, etc.) or detachably (by a linear fastener or other detachable material, for example).In addition, the retaining hole portion can also be formed using a flexible material (part of the flexible material that constitutes the tubular portion) that is integral with the flexible material that constitutes the tubular portion.

[0069] The retaining hole forming portion may be one in which the retaining hole is pre-formed, or one in which the retaining hole is formed by attaching the flexible material constituting the tubular portion to a required position in an irremovable or detachable manner by sewing or the like.

[0070] (3) Spring mouthpiece

[0071] (3-1) A pair of elastically bendable nozzle-shaped components (for example, a pair of leaf spring bodies of equal length, preferably substantially identical leaf spring bodies, or a pair of spring hinge-shaped bodies, or a leaf spring body and a spring hinge-shaped body) for forming a spring nozzle-shaped part are detachably held in the holding hole portion.

[0072] It is preferable that the retaining hole portion has a cross-sectional shape that is not easily deformed, for example, so that the spring plate that constitutes the retaining leaf spring, or the surface of the arm portion of the spring hinge body that closes the tubular portion, is accommodated along the inner surface of the tubular portion, or is easily accommodated in this manner.

[0073] Furthermore, in order to maintain the functionality of the pair of nozzle-shaped components held by the holding hole portion, it is desirable that the pair of nozzle-shaped components held by the holding hole portion be used in a state where they are kept as free from water as possible, for example, in a state where they are prevented from being exposed to the outside.

[0074] (3-2) One of the pair of nozzle-shaped portion constituents can be detachably held in a holding hole portion provided in a predetermined approximately half-circumferential portion in the circumferential direction of the tubular portion, and the other of the pair of nozzle-shaped portion constituents can be detachably held in a holding hole portion provided in the remaining approximately half-circumferential portion.

[0075] The pair of mouthpiece components held in the holding hole portion in this manner are One end of one nozzle-shaped component and one end of the other nozzle-shaped component are connected to each other so as to be rotatable about a predetermined rotation axis, and the other ends of both nozzle-shaped components are both free ends, and a spring nozzle-shaped component is formed that can open and close the tubular component when the free ends are adjacent to each other (directly or indirectly). Or, Both ends of the two nozzle-shaped components are free ends, and a spring nozzle-shaped component is formed that can open and close the cylindrical component in a state in which both free ends of one nozzle-shaped component are adjacent (directly or indirectly) to both free ends of the other nozzle-shaped component. It can be said that:

[0076] In either case, by applying a clamping pressure to the connected or adjacent both ends of both nozzle-shaped components by a force directed toward the other end, both nozzle-shaped components are bent outward from the tubular portion (usually, for example, so that the part between both end portions of the nozzle-shaped component protrudes outward, approximately perpendicular to the axial direction of the tube), thereby opening the tubular portion, and by releasing the clamping pressure, both nozzle-shaped components are elastically restored to their original position, and the tubular portion is closed.

[0077] When held in the retaining hole, the pair of nozzle-shaped components can be in a state in which they can close the tubular portion by moving along the front and back of the same plane, or in a state in which they can bend outward from the tubular portion to open it.

[0078] (4) Leaf spring body

[0079] The leaf spring as the base-shaped part constituent is made of a plate material having spring properties. The plate material constituting the leaf spring is usually a thin, vertically elongated rectangular plate, and is generally made of a metal such as iron or stainless steel, but is not limited to metal.

[0080] (4-1) When the nozzle-shaped portion constituent is a leaf spring body, a pair of leaf spring bodies accommodated in the retaining hole portion are connected at one end of one leaf spring body and one end of the other leaf spring body (for example, by a hinge-like connecting portion) so that they can rotate relative to each other around a predetermined rotation axis, and the other ends of both leaf spring bodies can both be free ends.

[0081] (4-2) The holding hole portion may have insertion / removal openings (for example, at one or two locations in the holding hole portion) for inserting and removing the pair of leaf springs in one direction from the free end of one leaf spring, via the connecting portion of the two leaf springs, to the free end of the other leaf spring. The insertion direction and the removal direction may be opposite (for example, when there is one insertion / removal opening portion), or may be the same direction (for example, when there are two insertion / removal opening portions).

[0082] (4-3) The pair of leaf spring bodies accommodated in the holding hole can form a spring mouthpiece by being held with the free ends adjacent to each other (without connecting the free ends to each other).

[0083] When a pair of leaf spring bodies constitute the spring mouthpiece portion in this manner, in a state in which no external force is substantially applied to the pair of leaf spring bodies, the corresponding surfaces of one leaf spring body and the other leaf spring body of the pair of leaf spring bodies maintain a state in which they sandwich the inner portions of the flexible sheet-like material that constitutes the retaining hole, and the cylindrical portion is maintained in a closed state at that portion (for example, an opening at one end of the cylindrical portion), By clamping the connection point (e.g., hinge-shaped connection portion) between the pair of leaf spring bodies and the free ends of both leaf spring bodies held adjacent to each other in the longitudinal direction of the leaf spring bodies, both leaf spring bodies can be bent outward from each other, opening the portion of the tubular portion where the retaining hole portion is located (e.g., the opening portion).

[0084] (4-4) In order to insert and hold the pair of leaf spring bodies in the retaining hole portion, the pair of leaf spring bodies held in the retaining hole portion can constitute a spring nozzle-shaped portion, and the pair of leaf spring bodies can be removed from the retaining hole portion, the tubular structure portion of the present invention can hold the free end of one leaf spring body inserted in the retaining hole portion and the free end of the other leaf spring body in a state where they are adjacent to each other (and can prevent the pair of leaf spring bodies from being removed from the retaining hole portion), and can have an adjacent retaining portion that can release the holding to remove the pair of leaf spring bodies from the retaining hole portion.

[0085] An example of such an adjacent holding portion is one that can releasably hold the portion of the tubular portion where the free end of one leaf spring body is located and the portion of the tubular portion where the free end of the other leaf spring body is located, with both free ends adjacent to each other, when the pair of leaf spring bodies are housed in the holding hole portion, preferably one that can block the insertion / removal opening portion when in the holding state and opens the insertion / removal opening portion when the holding state is released.

[0086] A more specific example of the adjacent holding portion is one that, when a pair of leaf springs are housed in the holding hole, detachably connects the outer periphery of the free end of one of the tubular leaf springs to the outer periphery of the free end and its adjacent portion of the other leaf spring, thereby holding the two free ends adjacent to each other. In this case, an example of the adjacent holding portion is one in which one end portion is fixedly connected to the outer periphery of the free end of one of the tubular leaf springs (or detachably connected by a detachable member such as a hook-and-loop fastener), and the other end portion is detachably attached to the outer periphery of the free end and its adjacent portion of the other leaf spring (by a detachable member such as a hook-and-loop fastener).

[0087] Examples of such adjacent holding portions include: When the retaining hole extends substantially around the entire circumference of the cylindrical portion with one end extending (for example, extending approximately one-sixth of the circumference), an extension of the retaining hole forming portion that constitutes the extended portion of the retaining hole (by accommodating a pair of leaf springs via the extension, and bending the extension at its base with the accommodated pair of leaf springs not positioned in the extension, the pair of leaf springs can be used while almost completely preventing exposure to the outside); Or, When the retaining hole portion extends almost around the entire circumference of the tubular portion, examples include a retaining portion that does not form a retaining hole portion (which can be used while preventing the pair of leaf spring bodies from being exposed to the outside to a considerable extent), and a portion of which is connected to the outer periphery of the retaining hole portion at one end (or can be attached and detached using a detachable material such as a hook-and-loop fastener).

[0088] Such an extension portion or retaining portion, etc., is preferably capable of blocking the insertion / removal opening portion when removably connected to the outer periphery of the free end of the other leaf spring body and its nearby portion of the tubular portion.

[0089] Another specific example is one in which, when a pair of leaf spring bodies are housed in a retaining hole, the portion of the tubular portion where the free end of one leaf spring body is located and the portion where the free end of the other leaf spring body is located can be connected by a connecting body (e.g., a wire fastener) that can be releasably connected (preferably, one that can block the insertion / removal opening when connected by the connecting body).

[0090] (4-5) The ends connected to each other so as to be rotatable about the predetermined rotation axis are preferably rotatable to an extent necessary for opening and closing between an open state and a nearly closed state when both leaf spring bodies are fitted together as a spring nozzle-shaped portion, and are rotatable to an extent that they can be inserted in one direction from the free end of one leaf spring body to the free end of the other leaf spring body with respect to the retaining hole portion and removed in one direction, as described above, and the two leaf spring bodies are preferably rotatable relative to each other by 180 degrees or more.

[0091] Furthermore, when the spring nozzle-shaped portion is configured as described above, the free ends of the pair of leaf spring bodies are held adjacent to each other in a state where they can rotate to the extent necessary to open and close between an almost closed state and an open state, with both leaf spring bodies coming together as the spring nozzle-shaped portion.

[0092] (4-6) At the opening or other position of the cylindrical portion, the retaining hole portion extending approximately one circumference or more along the circumferential direction of the cylindrical portion has an insertion / removal opening portion for inserting and removing one of the pair of leaf spring bodies from its free end and an insertion / removal opening portion for inserting and removing the other leaf spring body from its free end, which are adjacent to each other (the retaining holes may be separated or continuous at the insertion depth when the pair of leaf spring bodies are inserted, respectively), The plate spring may have a connection point holding portion that can hold the vicinity of the connection point of the two plate spring bodies in the two insertion / removal openings and can release the holding so as to remove the pair of plate spring bodies from the holding hole portion.

[0093] The connection point holding portion can be, for example, a connecting piece that does not form a holding hole portion and is partially attached to the outer periphery of one of the insertion / removal openings (or can be attached and detached by a detachable material such as a hook-and-loop fastener), and is connected to a detachable portion of the outer periphery of the tubular portion on the outer periphery of the other insertion / removal opening by a detachable material (preferably a hook-and-loop fastener), so that the vicinity of the connection point of both leaf spring bodies can be held in both insertion / removal openings, and the connection between the connecting piece and the detachable portion can be released to release the holding portion so as to remove the pair of leaf spring bodies from the holding hole portion.

[0094] The pair of leaf spring bodies inserted into the holding hole portion in this manner and held in the insertion / removal opening portions near the connection points of the two leaf spring bodies by the connection point holding portion constitute a spring nozzle-like portion that opens and closes the tubular portion.

[0095] The connection point holding portion can function to maintain the free ends of the pair of leaf spring bodies adjacent to each other, ensure that both free ends reach a predetermined position, and hold both leaf spring bodies in that state.

[0096] Furthermore, to ensure that the free ends of a pair of leaf spring bodies inserted into the retaining hole can be maintained adjacent to each other, an adjacent holding reinforcement section (for example, a reinforced section that allows the free ends to be adjacent to each other while being securely held, and to rotate by the required angle approximately around a predetermined rotation axis) can be provided near the location of the two free ends in the retaining hole in the cylindrical section, if necessary.

[0097] (5) Spring hinge-like body

[0098] The spring hinge-like body as the mouthpiece-like part component has a pair of arms that can rotate relative to each other around a predetermined hinge-like rotation axis, and an elastic biasing member that elastically biases the pair of arms. At least the tip end portion of each arm is, for example, an elongated plate-like part, particularly an elongated plate-like part with a constant width in the direction of the hinge-like rotation axis, and is made of, for example, but not limited to, a synthetic resin. The pair of spring hinge-like bodies constitute the spring mouthpiece-like part.

[0099] (5-1) The retaining hole may be made up of a pair of semi-circular portions (each of which may be connected at its end), each of which may have an outer opening at its circumferential center (opening toward the outer periphery of the retaining hole, such as perpendicularly outward relative to the circumferential direction).

[0100] The spring hinge body can be removably held in the holding hole by the pair of arm portions. For example, the pair of spring hinge bodies can be positioned in the outer opening with the hinge rotation axis of each body aligned substantially in the axial direction of the cylinder (perpendicular to the circumferential direction), and the pair of arm portions of each spring hinge body can be held in the semicircular portions on both sides of the outer opening.

[0101] (5-2) When the pair of arm-like portions are held in the retaining hole portion, at least certain parts of the arm-like portions on the inside of the tubular portion (the side that closes the tubular portion when the spring hinge-like body closes the tubular portion as a spring mouthpiece-like portion) can rotate relative to each other between a state in which the tubular portion can be closed by both of them moving along the same plane (for example, a plane parallel to the hinge-like rotation axis), and a state in which the spring hinge-like bodies can bend outward from the tubular portion and form an angle of less than 180 degrees with each other (the insides of the arm-like portions) to open the tubular portion.

[0102] (5-3) The pair of spring hinge-like bodies can be configured so that both ends of each body are the free ends of a pair of arm-like portions, and the two free ends of one spring hinge-like body are adjacent to the two free ends of the other spring hinge-like body (it is preferable that the free ends do not come into direct contact with each other within the retaining hole portion, but the free ends can also come into contact with each other), thereby forming a spring nozzle-like portion that can open and close the tubular portion.

[0103] The elastic biasing member elastically biases the pair of arm portions held in the retaining holes so that, in a state in which the tubular portion can be opened by the predetermined portions of the pair of arm portions forming an angle of less than 180 degrees with respect to each other (for example, 50 degrees to 90 degrees or more but less than 180 degrees), at least the predetermined portions are all aligned along the same plane (a state in which the tubular portion can be closed).The spring hinge-like body may be such that, even if the predetermined portions of the pair of arm portions are elastically biased by the elastic biasing member to an open state in which the angle between them exceeds 180 degrees when not held in the retaining holes, as long as the pair of arm portions are held in the retaining holes in a state in which they can close the tubular portion.

[0104] An example of such an elastic biasing member is a so-called kick spring, which receives a torsional moment around the hinged rotation axis when an external force is applied to open the tubular portion, causing the angle between the specified parts of the arm portion to be less than 180 degrees, and when the external force is released, the angle between the specified parts opens to approximately 180 degrees or exceeds 180 degrees.

[0105] (5-4) The pair of spring hinge-like bodies can be configured such that the spring mouth-like portion is closed when the specified portions of the pair of arm-like portions of each of the pair of spring hinge-like bodies are both along the front and back of the same plane, and the spring mouth-like portion is opened when the angle between the specified portions of the pair of arm-like portions of each of the spring hinge-like bodies is reduced to less than 180 degrees inside the semi-circular portion.

[0106] The two free ends of one spring hinge-like body are adjacent to the two free ends of the other spring hinge-like body, respectively, and when the spring mouth-like portion formed by the two spring hinge-like bodies is in a closed state, by clamping one adjacent free end of the two spring hinge-like bodies and the other adjacent free end of the two spring hinge-like bodies in the longitudinal direction of the spring hinge-like bodies, the pivotal connecting portions of the two spring hinge-like bodies open outward from each other and the inner angles of the semi-circular portions of each specified portion of the pair of arm-like portions of each spring hinge-like body become smaller than 180 degrees, thereby opening the spring mouth-like portion.

[0107] (6) Detubularization and restoration

[0108] (6-1) It is preferable that the cylindrical portion is such that at least a portion of the cylindrical portion can be made non-cylindrical and restored (to a cylindrical shape) so that the retaining hole portion (the retaining hole portion spanning both approximately semicircular portions) can be made straight or gently curved (for example, a gently curved curve substantially along a plane perpendicular to the cylindrical axis when the cylindrical portion is in a cylindrical shape) from one end to the other end of the retaining hole portion when the insertion / removal opening portion is one end (so that the pair of nozzle-shaped portion constituents [e.g., leaf spring bodies] can be inserted and removed as smoothly as possible from the free end of one nozzle-shaped portion constituent to the free end of the other nozzle-shaped portion constituent).

[0109] By removing the pair of nozzle-shaped components (e.g., leaf spring bodies) from the retaining hole in this manner, it is possible to, for example, wash or clean the tubular structure or an item including the tubular structure, or dry the inside or the entire structure.The pair of nozzle-shaped components can then be inserted through the retaining hole to restore the tubular structure (to a cylindrical shape), allowing the pair of nozzle-shaped components to function as spring nozzle-shaped components and the tubular structure to be used.

[0110] (6-2) The non-cylindrical transformation and restoration of at least a part of the cylindrical portion is performed, for example, by (i) The entire or a part of the cylindrical portion, including the retaining hole portion and other portions, can be opened to a flat or nearly flat state and restored to its original state, or (ii) This can be achieved by opening only the retaining hole, or the retaining hole and the vicinity of the retaining hole in the axial direction of the cylinder, to a flat or nearly flat state and making it possible to restore the original shape.

[0111] (i) In order to make all or part of the tubular part, including the retaining hole part and other parts, openable and restoreable to a flat or nearly flat state, it is possible to make at least part or all of the tubular part in the axial direction of the tube openable and closeable parallel to or at an angle to the tube axis using a linear fastener or other opening / closing device.

[0112] In this case, the opening / closing device can also serve as a connecting body that can releasably connect the portion of the tubular portion where the free end of one of the nozzle-shaped portion constituents is located and the portion of the other nozzle-shaped portion constituent where the free end is located when a pair of nozzle-shaped portion constituents (e.g., leaf spring bodies) are housed in the retaining hole portion.

[0113] (ii) To open only the retaining hole portion, or the retaining hole portion and the vicinity of the retaining hole portion in the axial direction of the cylinder, to a flat or nearly flat state and restore it to its original state, In the case where the portion extending from the opening at one end of the cylindrical portion to the insertion / removal opening of the retaining hole portion can be opened by, for example, releasing the retention by the adjacent retaining portion, at least a portion of the cylindrical portion (for example, approximately half a circumference or more) can be opened and closed along the retaining hole portion or approximately parallel to the retaining hole portion on the side of the retaining hole portion opposite the opening at one end of the cylindrical portion using a line fastener or other opening / closing device, or If a portion of the retaining hole that includes the insertion / removal opening but does not reach the opening at one end of the tubular portion can be opened by, for example, releasing the hold of the adjacent retaining portion, at least a portion of the tubular portion (for example, approximately half a circumference or more) can be opened and closed along or approximately parallel to the retaining hole on the side of the retaining hole that faces the opening at one end of the tubular portion and on the opposite side from the opening using a line fastener or other opening / closing device.

[0114] (7) The tubular portion constituting the storage section for storing an umbrella bag that can hold a rain-soaked umbrella or other items that carry moisture is preferably waterproof at least from the inside to the outside, and is preferably provided with a water-absorbing material (e.g., water-absorbing pile) on the entire or part of the inside (e.g., the entire or part of one side) so that it can absorb as much moisture as possible that may accompany the stored items.

[0115] For example, in the case of an umbrella bag, the number of umbrellas that can be stored is usually one or up to two, but is not necessarily limited to these. The umbrellas that can be stored can be, for example, folding umbrellas or non-folding umbrellas (long umbrellas).

[0116] If the opening or other position of the tubular portion can be opened and closed by a spring-like portion, by providing a water-absorbing material (e.g., water-absorbing pile) on at least the whole or part (e.g., one side) of the inside or its vicinity (e.g., the inner or outer vicinity of the opening) that opens and closes by the spring-like portion, it is possible to prevent moisture accompanying an item such as a wet umbrella from leaking out when the item is stored in the tubular portion, and also to enable the user, when storing the item in the tubular portion, to slightly close the spring-like portion as necessary, thereby absorbing as much moisture as possible that may accompany the item.

[0117] The shape of the cylindrical portion is preferably a straight line, and can have a constant width or thickness from the opening at one end to the other end, but this is not necessarily limited to this, and it can also be, for example, tapered toward the other end.

[0118] The cylindrical portion may also be provided with a hanging string, a detachable string, a connecting ring, a hook, etc., for attaching or detaching it to a handbag or bag, for carrying it on the shoulder, or for hanging it at an appropriate location.

[0119] (8) The water-absorbing material may be, for example, a pile-shaped water-absorbing material made of the following pile-forming material, but is not limited thereto.

[0120] (8-1) This pile-forming body is of a generally cylindrical shape, and is made up of single fibers, preferably 0.03 to 3 denier, having poor water absorption, closely spaced radially from the axis of the pile-forming body and closely spaced axially, with the outer periphery of the generally cylindrical shape being formed by the tips of the single fibers.

[0121] The density of the single fibers in the pile-forming body increases from the surface toward the inside of the pile-forming body, and a strong liquid-absorbing force acts toward the inside of the pile-forming body due to capillary action, so the pile-shaped water-absorbing material can quickly absorb a relatively large amount of water (which may be water containing other components or other liquids) from the surface where the tips of the single fibers are located toward the inside of the pile-forming body.

[0122] The outer periphery of the pile-forming body that has absorbed water in this way has a low moisture content due to capillary action, and because this outer periphery is formed from the tips of single fibers that have poor water absorption, the area occupied by the fibers is relatively small and the fibers themselves remain non-wet. Therefore, the outer periphery that has absorbed water is likely to remain relatively dry.

[0123] An example of the pile-forming body is a pile-forming body having a base portion joined to a base fabric joined to the inside of an elongated bag-like body and a free tip portion, the tip portion of which has a generally convex curved surface formed by the tips of monofilaments serving as decorative threads densely arranged in a generally radial pattern from the tip of a core thread.

[0124] (8-2) Such a pile-forming body uses a mohair yarn, which is a number of decorative yarns (preferably 0.03 to 3 denier) with poor water absorption that are not twisted together and are held transversely to the core yarn at the middle of the decorative yarn, and two mohair yarns formed by folding the mohair yarn back are twisted together around the core yarn of each mohair yarn, and the twisted part forms a single mohair yarn with the folded back part as its tip, and the tip can be made to have a roughly convex curved shape due to the tips of the decorative single fibers that are closely spaced so as to radiate from the tip of the core yarn.

[0125] (8-3) The water absorption rate of a single fiber having poor water absorption can be, for example, 3% or less at 20°C and a relative humidity of 65%. Preferably, it is 2% or less, and more preferably 1% or less, at 20°C and a relative humidity of 65%. Such a single fiber can be made of, for example, a filament of polyester fiber, polypropylene fiber, polyethylene fiber, polyamide fiber, or the like, and if necessary, all or part of the single fiber can be subjected to a hydrophilization treatment using various surfactants or the like.

[0126] The fineness of the single fiber is preferably 0.03 to 3 denier, more preferably 0.03 to 1.5 denier, and can be 1.2 denier or less, 1 denier or less, or 0.8 denier or less.

[0127] In this case, the single fibers used as decorative threads can be, for example, about 10,000 to 250,000 fibers per 1 cm of axial length of the twisted portion (the number can be smaller or larger depending on the fineness of the single fibers. In the case of a 0.7 denier single fiber, for example, about 50,000 fibers per 1 cm of axial length of the twisted portion), closely spaced radially and in the axial direction around the axis of the twisted portion.

[0128] The core yarn may be, for example, a 10 to 300 denier monofilament yarn, a spun yarn, or a multifilament twisted yarn, but is not limited thereto. The heat-sealable yarn may also be used. The core yarn may be, for example, a polyester fiber, a polypropylene fiber, a polyethylene fiber, or a polyamide fiber, but is not limited thereto. [Explanation of symbols]
