Description

[Technical field]

[0001] The present invention relates to an umbrella, and more particularly to a disassembled umbrella. [Background technology]

[0002] Umbrellas that can be disassembled and assembled are known. For example, Patent Document 1 discloses a disassembly and assembly-free umbrella consisting of a center rod, a top wheel, a ferrule, a bottom wheel, ribs with locking projections at the top wheel side end, ribs with locking projections at the bottom wheel side end, and an umbrella base. In this disassembly and assembly-free umbrella, the top wheel has a rib locking groove into which the locking projections at the ends of the ribs are inserted from above with the ferrule side facing up to lock the ribs including the support ends from below so that they can rotate freely, and a rib slip-out prevention part that can be screwed in and detached to rotatably close the ribs including the ends above the rib locking groove to prevent the rib ends from slipping out of the rib locking groove. The lower wheel has a rib locking groove into which the locking protrusions on the ends of the ribs are inserted from above when the ferrule is placed with the ferrule tip facing down, thereby locking the ribs including the support ends from below so that they can rotate freely, and a rib slip-out prevention part that can be screwed in and detached to rotatably cover the ribs including their ends above the rib locking groove to prevent the rib ends from slipping out of the rib locking groove. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2019-129904 A Summary of the Invention [Problem to be solved by the invention]

[0004] If an umbrella can be disassembled and reassembled, even if some parts are damaged, you can replace them yourself. Therefore, such umbrellas can be used for a long time, which contributes to reducing the number of umbrellas that are discarded, and also meets the Sustainable Development Goals (SDGs).

[0005] In Patent Document 1, a circular runner surrounding the center rod has multiple rib locking grooves arranged at equal intervals along its circumferential surface. When attaching multiple ribs to the runner, first, each end of the multiple ribs is inserted into each of the multiple rib locking grooves. Then, the multiple rib locking grooves are covered with a circular rib removal prevention part. Through these steps, each end of the multiple ribs is rotatably fixed to each of the multiple rib locking grooves, and the multiple ribs are attached to the runner. On the other hand, when removing the multiple ribs from the runner, the attachment steps can be carried out in reverse.

[0006] When the bone engaging grooves are covered with the bone retaining prevention part, the bone retaining prevention part is fixed to the runner by a screw mechanism. That is, the runner has a male screw structure, the bone retaining prevention part has a female screw structure, and the two are screwed together to fix the bone retaining prevention part to the runner.

[0007] Therefore, when attaching and detaching multiple ribs to and from the wheel, it is necessary to rotate the rib removal prevention part in a specified direction to connect the screw part, and to rotate it in the opposite direction to the specified direction to remove the screw part. This can make the attachment and detachment work complicated. Therefore, there is room for improvement in the structure for attaching and detaching multiple ribs to and from the wheel.

[0008] In addition, in Patent Document 1, the center of the umbrella fabric is sandwiched between the top wheel and the ferrule, and multiple ribs are engaged with multiple tips connected to the ends of the umbrella fabric, thereby fixing the umbrella fabric to the umbrella. In other words, the umbrella fabric is not fixed to the ribs by sewing or gluing.

[0009] Therefore, when the umbrella is closed, there is a possibility that the umbrella fabric may separate from the ribs between the ferrule and the tip. If this happens, even if the belt to prevent the umbrella from opening is fastened, the umbrella fabric between the ferrule and the tip may bulge outward and get caught on something outside, causing it to tear or get damaged. However, if the umbrella fabric is fixed to the ribs between the ferrule and the tip by sewing or gluing, it may become difficult to attach and detach the umbrella fabric from the ribs. Therefore, there is room for improvement in the structure for attaching and detaching the umbrella fabric to the ribs between the ferrule and the tip.

[0010] The object of the present invention is to provide an umbrella that can be disassembled and assembled, in which a plurality of ribs can be easily attached and detached to the runner. Another object of the present invention is to provide an umbrella that can be disassembled and assembled, in which the umbrella fabric can be easily attached and detached to the ribs between the ferrule and the tip. [Means for solving the problem]

[0011] One embodiment of the umbrella of the present invention is a disassemblable umbrella having a center rod, a ferrule, a top wheel, a bottom wheel, multiple ribs, multiple dowels, multiple ribs, and an umbrella material, each of the multiple ribs having a rib engagement protrusion at one end, the bottom wheel having a main body member, a bottom wheel auxiliary member provided on the underside of the main body member, and a connecting and fixing member that fixes the connection between the main body member and the bottom wheel auxiliary member, the main body member having a plurality of rib engagement grooves provided on its upper end into which the multiple rib engagement protrusions of the multiple ribs can be inserted from below, the bottom wheel auxiliary member can be connected so that its upper end overlaps the lower end of the main body member, and the connecting and fixing member is detachable from the bottom wheel.

[0012] Another aspect of the umbrella of the present invention is a disassemblable umbrella comprising a center pole, a ferrule, a top wheel, a bottom wheel, multiple ribs, multiple dowels, multiple support ribs, and umbrella fabric, and further comprising umbrella fabric side locking members attached to portions of the umbrella fabric facing each of the multiple dowels, each of the multiple dowels having a dowel side locking portion facing the umbrella fabric, and the umbrella fabric can be attached and detached from the ribs by locking or unlocking the dowel side locking portion and the umbrella fabric side locking member. Effect of the Invention

[0013] According to the present invention, it is possible to provide an umbrella that can be disassembled and assembled, in which a plurality of ribs can be easily attached and detached to and from the wheel. Also, according to the present invention, it is possible to provide an umbrella that can be disassembled and assembled, in which the umbrella fabric can be easily attached and detached to and from the ribs between the ferrule and the tip.

[Figure 6] FIG. 2 is a perspective view showing an example of the configuration of a dowel of an umbrella according to an embodiment. [Figure 7] 1 is a perspective view showing an example of the configuration of an umbrella fabric side fastening member of an umbrella according to an embodiment. FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] The present disclosure specifically relates to the following aspects: [Aspect 1] said runner main body member includes a plurality of rib engagement grooves provided on an upper end thereof and into which the plurality of rib engagement protrusions of said plurality of ribs can be inserted from below; said runner auxiliary member is connectable to said runner main body member such that its upper end overlaps with a lower end of said runner auxiliary member; and said connecting and fixing member is detachable from said runner main body member.

[0016] The umbrella of this embodiment has the above-mentioned structure. Therefore, the ribs can be easily attached to and detached from the wheel by the following steps. The process of removing the ribs from the runner includes first removing the connecting and fixing member from the runner. This releases the connection between the runner main body and the runner auxiliary member. Next, the runner auxiliary member is moved downward to remove it from the runner main body member. This means that the runner auxiliary member no longer covers the rib locking grooves of the runner, allowing the rib locking projections of the ribs inserted into the rib locking grooves to be removed downward. On the other hand, the process of attaching the ribs to the runner includes first inserting the rib locking projections of the ribs into the rib locking grooves of the runner, and connecting the upper end of the runner auxiliary member to the lower end of the runner main body member. This allows the rib locking grooves of the runner to be covered with the runner auxiliary member. Next, a connecting and fixing member is attached to the runner. This fixes the connection between the runner main body member and the runner auxiliary member. At this time, since the rib locking grooves are covered with the runner auxiliary member, it is possible to prevent the rib locking projections inserted into the rib locking grooves from coming off downward.

[0017] [Aspect 2] The umbrella of embodiment 1, wherein the runner main body member includes a main body side hole portion provided in a lower portion and penetrating toward the center rod, the runner auxiliary member includes an auxiliary side hole portion provided in an upper portion and penetrating toward the center rod, and the connecting and fixing member includes an extension portion that is inserted from one of the main body side hole portion and the auxiliary side hole portion to the other when the runner main body member and the runner auxiliary member are connected and the main body side hole portion and the auxiliary side hole portion overlap to fix the connection.

[0018] The umbrella of this embodiment has the above-mentioned configuration. Therefore, when removing the connecting and fixing member of the runner in the process of removing the ribs from the runner, the extension part of the connecting and fixing member that extended into the main body side hole part and the auxiliary side hole part is pulled out from the main body side hole part and the auxiliary side hole part. This makes it possible to easily release the connection between the runner main body part and the runner auxiliary part. On the other hand, in the process of attaching the ribs to the runner, after connecting the upper end of the runner auxiliary part to the lower end of the runner main part, when attaching the connecting and fixing part to the runner auxiliary part, the extensions of the connecting and fixing part are inserted through the main body side hole and the auxiliary side hole, thereby easily fixing the connection between the runner main part and the runner auxiliary part.

[0019] [Aspect 3] The umbrella of aspect 2, wherein the connecting and fixing member further includes a pair of connecting and fixing member main bodies extending along the outer peripheral surface of the wheel auxiliary member, and an elastic portion connecting one ends of the pair of connecting and fixing member main bodies, and the extension portion is located at the other end of at least one of the pair of connecting and fixing member main bodies and extends toward the center pole.

[0020] The umbrella of this embodiment has the above-mentioned configuration, so that in the process of removing the ribs from the runner, by mainly deforming the elastic member so as to move the pair of connecting and fixing member bodies away from each other, the extension parts that extended into the main body side hole and the auxiliary side hole can be more easily pulled out from the main body side hole and the auxiliary side hole. On the other hand, in the process of attaching the ribs to the runner, after connecting the upper end of the runner auxiliary member to the lower end of the runner main body member, the connecting and fixing members are positioned on the outer peripheral surface of the runner auxiliary member while mainly deforming the elastic member so that the pair of connecting and fixing member bodies move away from each other, thereby making it easier to insert the extension portions of the connecting and fixing members into the main body side hole portion and the auxiliary side hole portion.

[0021] [Aspect 4] The umbrella described in aspect 3, wherein each of the multiple ribs has a rib engagement protrusion at one end, the ferrule has a cover portion and a tapered protrusion extending from the cover portion, the runner has a plurality of rib engagement grooves provided at an upper end portion into which the multiple rib engagement protrusions of the multiple ribs can be inserted from above, and an insertion portion provided on the upper surface of the upper end portion into which the protrusions are inserted to connect the ferrules, the elastic portion connects one ends of the pair of connecting and fixing member bodies while forming a gap between it and the outer peripheral surface of the runner auxiliary member, and the protrusion can be inserted into the gap formed between the elastic portion and the outer peripheral surface of the runner auxiliary member.

[0022] The umbrella of this embodiment has the above-mentioned structure. Therefore, the ribs can be easily attached to and detached from the upper wheel by the following steps. The process of removing the ribs from the wheel includes removing the ferrule from the wheel body, so that the rib locking grooves of the wheel are no longer covered by the ferrule covers, allowing the rib locking projections of the ribs inserted into the rib locking grooves to be removed upward. Meanwhile, the process of attaching the ribs to the wheel includes inserting the rib locking projections of the ribs into the rib locking grooves of the wheel. Then, the ferrule and the ferrule are joined by inserting the projections of the ferrule into the joining holes of the wheel body. This attaches the ferrule to the wheel. At this time, the rib locking grooves are covered with the ferrule lids, so that the rib locking projections inserted into the rib locking grooves are prevented from coming off upward. In addition, the umbrella of this embodiment has the above-mentioned configuration. Therefore, in the process of removing the ribs from the wheel, the tip of the removed ferrule protrusion can be inserted into the gap formed between the elastic part of the wheel and the outer circumferential surface of the wheel auxiliary member, thereby deforming the elastic part. This causes the pair of connecting and fixing member bodies to deform away from each other, making it easier to pull out the extension parts inserted in the main body side hole and the auxiliary side hole from the main body side hole and the auxiliary side hole.

[0023] [Aspect 5] The umbrella described in aspect 1 or 2 further comprises an umbrella fabric side locking member attached to a position opposite each of the plurality of dowels on the umbrella fabric, each of the plurality of dowels having a dowel side locking portion at a portion opposite the umbrella fabric side locking member, and the umbrella fabric is attached and detached from the ribs by engaging or disengaging the dowel side locking portion and the umbrella fabric side locking member.

[0024] The umbrella of this embodiment has the above-mentioned structure. Therefore, the ribs can be easily attached and detached from the lower wheel, the ribs can be easily attached and detached from the upper wheel, and the umbrella fabric can be easily attached and detached from the ribs between the ferrule and the tip by the following steps. The process of removing the umbrella fabric from the dowel involves disengaging (unlocking) the umbrella fabric side fastening member of the umbrella fabric from the dowel side fastening portion of the dowel while fixing the dowel, thereby allowing the umbrella fabric (umbrella fabric side fastening member) to be removed from the dowel (dowel side fastening portion). The process of attaching the umbrella fabric to the dowel involves fixing the dowel while engaging (locking) the umbrella fabric side locking member of the umbrella fabric with the dowel side locking portion of the dowel. This allows the umbrella fabric (umbrella fabric side locking member) to be attached to the dowel (dowel side locking portion).

[0025] [Aspect 6] A disassemblyable umbrella comprising a center rod, a ferrule, a top wheel, a bottom wheel, multiple ribs, multiple dowels, multiple support ribs, and an umbrella fabric, further comprising umbrella fabric side locking members attached to portions of the umbrella fabric facing each of the multiple dowels, each of the multiple dowels having a dowel side locking portion facing the umbrella fabric, and the dowel side locking portion and the umbrella fabric side locking member lock or unlock to attach and detach the umbrella fabric to and from the ribs.

[0026] The umbrella of this embodiment has the above-mentioned structure. Therefore, the umbrella fabric can be easily attached to and detached from the ribs between the ferrule and the tip by the following steps. The process of removing the umbrella fabric from the dowel involves disengaging (unlocking) the umbrella fabric side fastening member of the umbrella fabric from the dowel side fastening portion of the dowel while fixing the dowel, thereby allowing the umbrella fabric (umbrella fabric side fastening member) to be removed from the dowel (dowel side fastening portion). The process of attaching the umbrella fabric to the dowel involves fixing the dowel while engaging (locking) the umbrella fabric side locking member of the umbrella fabric with the dowel side locking portion of the dowel. This allows the umbrella fabric (umbrella fabric side locking member) to be attached to the dowel (dowel side locking portion).

[0027] [Aspect 7] The umbrella of aspect 6, wherein the dowel side fastening portion is a female fastening portion, and the umbrella fabric side fastening member is a male fastening portion.

[0028] In this umbrella, if the dowel-side locking part is a male locking part, the male part (protruding part) of the locking part may get caught on the umbrella fabric that is in contact with the dowel, and may damage or tear the umbrella fabric. Therefore, in this umbrella, the dowel-side locking part is a female locking part. This makes it easier to attach and detach the umbrella fabric from the ribs while making it less likely to damage the umbrella fabric.

[0029] [Aspect 8] The umbrella of aspect 6 or 7, wherein the dowel side locking portion has a space provided inside the dowel and an opening penetrating from the surface of the dowel into the space, wherein in the opening, an opening first length in a first direction is longer than an opening second length in a second direction perpendicular to the first direction, and in the space, the space first length and the space second length in the first direction and second directions are longer than the opening first length, and the umbrella fabric side locking member includes a joint that is rotatably joined to the umbrella fabric and an elongated portion connected to the joint, and the longitudinal length of the elongated portion is shorter than the opening first length and longer than the opening second length.

[0030] The umbrella of this embodiment has the above-mentioned structure. Therefore, the umbrella fabric can be more easily attached to and detached from the ribs between the ferrule and the tip by the following steps. The process of removing the umbrella fabric from the dowel of the rib involves fixing the dowel of the rib while pinching the joint of the umbrella fabric side fastening member and rotating it by an appropriate angle to align the longitudinal direction of the elongated part of the umbrella fabric side fastening member with the first direction of the opening of the dowel side fastening part. Then, the elongated part whose longitudinal length is shorter than the first opening length is pulled out from the opening. This allows the umbrella fabric (umbrella fabric side fastening member) to be removed from the dowel of the rib (dowel side fastening part). The process of attaching the umbrella fabric to the dowel of the rib involves pinching the joint of the umbrella fabric side locking member and rotating it by an appropriate angle while fixing the dowel of the rib, so that the longitudinal direction of the slender part of the umbrella fabric side locking member coincides with the first direction of the opening of the dowel side locking part. Next, the slender part, whose longitudinal length is shorter than the first length of the opening, is inserted into the opening. Then, the joint is rotated again by an appropriate angle to shift the longitudinal direction of the slender part of the umbrella fabric side locking member from the first direction of the opening of the dowel side locking part, so that the slender part cannot be pulled out of the opening. This allows the umbrella fabric (umbrella fabric side locking member) to be attached to the dowel of the rib (dowel side locking part).

[0031] [Aspect 9] The umbrella of aspect 6 or 7, wherein each of the multiple ribs has a rib engagement protrusion at one end, and the runner comprises a runner main body member, a runner auxiliary member provided on the underside of the runner main body member and connectable so that its upper end overlaps with the lower end of the runner main body member, and a connecting and fixing member detachable from the runner and fixing the connection between the runner main body member and the runner auxiliary member.

[0032] The umbrella of this embodiment has the above-mentioned structure. Therefore, the umbrella fabric can be easily attached to and detached from the ribs between the ferrule and the tip, and the ribs can be easily attached to and detached from the wheel by the following steps. The process of removing the ribs from the runner includes first removing the connecting and fixing member from the runner. This releases the connection between the runner main body and the runner auxiliary member. Next, the runner auxiliary member is moved downward to remove it from the runner main body member. This means that the runner auxiliary member no longer covers the rib locking grooves of the runner, allowing the rib locking projections of the ribs inserted into the rib locking grooves to be removed downward. On the other hand, the process of attaching the ribs to the runner includes first inserting the rib locking projections of the ribs into the rib locking grooves of the runner, and connecting the upper end of the runner auxiliary member to the lower end of the runner main body member. This allows the rib locking grooves of the runner to be covered with the runner auxiliary member. Next, a connecting and fixing member is attached to the runner. This fixes the connection between the runner main body member and the runner auxiliary member. At this time, since the rib locking grooves are covered with the runner auxiliary member, it is possible to prevent the rib locking projections inserted into the rib locking grooves from coming off downward.

[0033] [Aspect 10] 7. The umbrella of claim 1 or 6, wherein the umbrella is a folding umbrella.

[0034] A folding umbrella requires a process of folding from an open state and opening from a folded state before and after use, so there is a high possibility that parts will break compared to a normal umbrella. Therefore, the umbrella of this embodiment is a folding umbrella, but as described above, the runner or the dowel has a specific configuration. This allows multiple ribs to be easily attached and detached to the runner, or allows the umbrella fabric to be easily attached and detached to the rib between the ferrule and the tip.

[0035] The disassembled umbrella 1 according to the embodiment will be described below with reference to the drawings. However, the umbrella 1 of the present invention is not limited to the configuration of the embodiment described below, and can be appropriately combined with other technologies, substituted, modified, etc., within the scope of the purpose and intent of the present invention. The type of umbrella 1 is not particularly limited, and it may be a folding umbrella.

[0036] First, the overall structure of the umbrella 1 will be described. FIG. 1 is a schematic diagram showing an example of the structure of a disassembled umbrella 1 according to an embodiment. The umbrella 1 includes a center pole 2, a ferrule 3, a top wheel 4, a bottom wheel 5, a plurality of ribs 6, a plurality of dowels 7, a plurality of support ribs 8, and an umbrella material 9. In this embodiment, the umbrella material side locking member 10, an upper stopper 11, a tip 12, a lower stopper 13, a ball stopper 14, and a handle 15 are further included. In the umbrella 1, the "vertical direction V" is the same direction as the central axis of the center pole 2, the "circumferential direction H" is the direction along the circumferential surface of a cylinder perpendicular to the vertical direction V and having the same central axis as the center pole 2, and the "radial direction R" is the direction of the diameter of a cylinder perpendicular to the vertical direction V and having the same central axis as the center pole 2. The "planar view" refers to viewing an object from above the vertical direction V. The up / upper side of the up-down direction V is the direction / side from the hand tip 15 to the ferrule 3, and the down / lower side is the direction / side from the ferrule 3 to the hand tip 15. "Side view" refers to viewing an object from the outside in the radial direction R. The inner / inner side of the radial direction R is the direction / side relatively facing the center rod 2 (its central axis), and the outer / outer side is the direction / side relatively facing away from the center rod 2 (its central axis). These directions apply not only to the umbrella 1 as a whole, but also to each component of the umbrella 1.

[0037] Of the above-mentioned components of the umbrella 1, there are no particular limitations on the configurations of the center rod 2, multiple ribs 6, multiple support ribs 8, umbrella fabric 9, upper flap 11, tip 12, lower flap 13, ball retainer 14, and handle 15, and conventionally known configurations can be used.

[0038] Fig. 2 shows an example of the configuration of the ferrule 3 of the umbrella 1 according to the embodiment, with Fig. 2(a) being a top view and Fig. 2(b) being a front view. The ferrule 3 is a jig that fixes the center of the umbrella material 9 to the wheel 4 and prevents the multiple ribs 6 installed on the wheel 4 from coming off the wheel 4. The ferrule 3 has a lid portion 3a provided on the upper side in the vertical direction V and a protruding portion 3b provided on the lower side.

[0039] The lid portion 3a has, for example, a substantially disk shape. However, the shape of the lid portion 3a is not limited to this example, and may have any other shape, such as a substantially conical shape, a substantially truncated conical shape, a substantially spindle shape, or a substantially spherical shape.

[0040] The protrusion 3b extends downward on the lower surface of the lid 3a in the vertical direction V and has a tapered shape. In this embodiment, the upper part of the protrusion 3b in the vertical direction V is cylindrical with a smaller radius than the lid 3a, has a screw thread on its outer circumferential surface, and functions as a male screw, and the lower part is conical and pointed downward.

[0041] 3 is a perspective view showing an example of the configuration of the upper wheel 4 of the umbrella 1 according to the embodiment. The upper wheel 4 is a jig located at the upper end of the center pole 2 in the vertical direction V, which rotatably holds one end of the multiple ribs 6 and clamps and fixes the center of the umbrella material 9 together with the ferrule 3. The upper wheel 4 has an upper part 4c provided on the upper side in the vertical direction V, and a lower part 4d provided on the lower side.

[0042] The upper portion 4c has a generally circular plate or cylindrical shape. The lower portion 4d has a generally circular plate or cylindrical shape with a smaller diameter than the upper portion 4c, and has a recess 4f with a circular cross section provided on the lower side into which the center rod 2 is inserted. The upper portion 4c, the lower portion 4d, and the recess are coaxial with each other (they are coaxial). The upper wheel 4 has a plurality of rib engagement grooves 4a provided in the upper portion 4c (the upper end portion of the upper wheel 4) and an insertion portion 4b provided on the upper surface of the upper portion 4c (the upper end portion of the upper wheel 4).

[0043] The rib locking grooves 4a are formed at intervals along the outer circumferential surface of the upper portion 4c (along the circumferential direction H) in the same number as the ribs 6. Each rib locking groove 4a is a groove into which a rib locking protrusion (not shown) provided at one end of each of the ribs 6 can be inserted from above in the up-down direction V. Each rib locking groove 4a rotatably holds the rib locking protrusion of each rib 6 inserted therein.

[0044] The insertion portion 4b is formed at the center of the upper surface of the upper portion 4c. It is a hole into which the protrusion 3b of the ferrule 3 can be inserted. The protrusion 3b is inserted into the insertion portion 4b and coupled, so that the ferrule 3 is coupled to the upper wheel 4. There is no particular limitation on the manner in which the insertion portion 4b and the protrusion 3b are coupled, but examples of the coupling structure include a coupling structure in which the protrusion 3b is coupled to the insertion portion 4b, a locking structure in which the protrusion 3b is locked, and a screwing structure in which the protrusion 3b is screwed. In this embodiment, the insertion portion 4b has a circular cross section, and its inner peripheral surface is threaded to function as a female screw. Therefore, the portion of the protrusion 3b that functions as a male screw and the portion of the insertion portion 4b that functions as a female screw are screwed together and coupled.

[0045] Here, to fix the ribs 6 to the top wheel 4, first, the rib locking protrusions of the ribs 6 are inserted into the rib locking grooves 4a. Next, the umbrella fabric 9 is placed over the top wheel 4, and the protruding parts 3b of the ferrules 3 are inserted into the insertion parts 4b of the top wheel 4, so that the ferrules 3 are joined to the top wheel 4. As a result, the rib locking grooves 4a are covered with the cover parts 3a. This allows the rib locking protrusions of the ribs 6 to be confined in the rib locking grooves 4a while still being able to rotate freely. In other words, the rib locking protrusions can be prevented from slipping out of the rib locking grooves 4a, and the ribs 6 can be fixed to the top wheel 4. When removing the ribs 6 from the top wheel 4, the above steps are carried out in reverse.

[0046] When fixing the rib 6 to the wheel 4, the protruding part 3b of the ferrule 3 is inserted into a hole (not shown) in the center of the umbrella base 9, and the ferrule 3 is joined to the wheel 4, thereby clamping the umbrella base 9 between the wheel 4 and the ferrule 3, thereby fixing the position of the umbrella base 9.

[0047] 4 and 5 are perspective views showing an example of the configuration of the runner 5 of the umbrella 1 according to the embodiment. Fig. 4 shows the runner main body member 5-1 and the runner auxiliary member 5-2 (described later), and Fig. 5 shows the connecting and fixing member 5-3 (described later). The runner 5 is a jig that surrounds a part of the outer circumferential surface of the center rod 2, is held on the outer circumferential surface in a vertical direction V so as to be slidable thereon, and holds one end of a plurality of ribs 8 rotatably. The runner 5 includes a runner main body member 5-1 located above the runner 5 in the vertical direction V, a runner auxiliary member 5-2 provided below the runner main body member 5-1 in the vertical direction V, and a connecting and fixing member 5-3 that fixes the connection between the runner main body member 5-1 and the runner auxiliary member 5-2.

[0048] With reference to Fig. 4, the runner main body member 5-1 includes an upper main body portion 5-1c provided on the upper side in the vertical direction V, and a lower main body portion 5-1d provided on the lower side. The upper main body portion 5-1c has a generally circular plate or cylindrical shape. The lower main body portion 5-1d has a generally circular plate or cylindrical shape with a smaller diameter than the upper main body portion 5-1c. The upper main body portion 5-1c and the lower main body portion 5-1d have a through hole 5-1f with a circular cross section into which the center rod 2 is inserted. The central axes of the upper main body portion 5-1c, the lower main body portion 5-1d, and the through hole 5-1f overlap (are coaxial).

[0049] The runner main body member 5-1 includes a plurality of rib engagement grooves 5-1a provided in the upper body portion 5-1c (the upper end portion of the runner main body member 5-1), and a body side hole 5-1e provided in the lower body portion 5-1d (the lower portion of the runner main body member 5-1) that penetrates from its outer circumferential surface toward the center rod 2. There may be one or more body side holes 5-1e. In this embodiment, there are two, provided on opposite sides of the center rod 2.

[0050] The multiple rib locking grooves 5-1a are formed at intervals along the outer circumferential surface of the main body upper portion 5-1c (along the circumferential direction H) in the same number as the multiple ribs 8. Each rib locking groove 5-1a is a groove into which a rib locking protrusion (not shown) provided at one end of each of the multiple ribs 8 can be inserted from below in the up-down direction V. Each rib locking groove 5-1a rotatably holds the rib locking protrusion of each rib 8 inserted therein.

[0051] The wheel auxiliary member 5-2 includes an auxiliary upper portion 5-2c provided at the upper end in the vertical direction V, and an auxiliary lower portion 5-2d provided below the auxiliary upper portion 5-2c. The auxiliary upper portion 5-2c has a generally circular plate or cylindrical shape. The auxiliary lower portion 5-2d has a portion having a generally circular plate or cylindrical shape with a smaller diameter than the auxiliary upper portion 5-2c, and a portion below the portion. The auxiliary upper portion 5-2c and the auxiliary lower portion 5-2d have a through hole 5-2f having a circular cross section into which the center rod 2 is inserted. The central axes of the auxiliary upper portion 5-2c, the auxiliary lower portion 5-2d, and the through hole 5-2f overlap (they are coaxial).

[0052] The runner auxiliary member 5-2 can be connected so that its upper end (the upper part of the auxiliary upper part 5-2c and the auxiliary lower part 5-2d) overlaps with the lower end (the main body lower part 5-1d) of the runner main body member 5-1. In this embodiment, the upper parts of the auxiliary upper part 5-2c and the auxiliary lower part 5-2d are located on the outside, and the main body lower part 5-1d is located on the inside, and the auxiliary upper part 5-2c and the auxiliary lower part 5-2d are connected so that their upper parts overlap the outside of the main body lower part 5-1d. However, the main body lower part 5-1d may be connected so that it overlaps the outside of the upper parts of the auxiliary upper part 5-2c and the auxiliary lower part 5-2d (in this case, the connecting and fixing member 5-3 is connected to the main body lower part 5-1d instead of the auxiliary lower part 5-2d).

[0053] The runner auxiliary member 5-2 is provided in the auxiliary lower portion 5-2d (the upper portion of the runner auxiliary member 5-2) and includes auxiliary side holes 5-2e that penetrate from its outer circumferential surface toward the center rod 2. There may be one or more auxiliary side holes 5-2e, as long as the number is the same as the number of main body side holes 5-1e. In this embodiment, there are two auxiliary side holes, which are provided on opposite sides of the center rod 2. The auxiliary side holes 5-2e are formed at positions that overlap with the main body side holes 5-1e in the radial direction R when the runner main body member 5-1 and the runner auxiliary member 5-2 are connected.

[0054] 5, the connecting and fixing member 5-3 is detachable from the runner 5 (the runner auxiliary member 5-2). In this embodiment, the connecting and fixing member 5-3 includes an extension portion 5-3a, a pair of connecting and fixing member bodies 5-3b, and an elastic portion 5-3c.

[0055] The pair of connecting and fixing member bodies 5-3b extend along the outer peripheral surface of the runner auxiliary member 5-2 when the connecting and fixing member 5-3 is attached to the runner auxiliary member 5-2 (the upper part of the auxiliary lower portion 5-2d).

[0056] The elastic portion 5-3c connects one end of the pair of connecting and fixing member bodies 5-3b to each other. In this embodiment, the elastic portion 5-3c connects one end of the pair of connecting and fixing member bodies 5-3b to each other while forming a gap 5-3d between the elastic portion 5-3c and the outer peripheral surface of the runner auxiliary member 5-2 (the portion above the auxiliary lower portion 5-2d). The protruding portion 3b of the ferrule 3 can be inserted into the gap 5-3d formed between the elastic portion 5-3c and the outer peripheral surface of the runner auxiliary member 5-2 (the portion above the auxiliary lower portion 5-2d).

[0057] The extension portion 5-3a is located at the other end of at least one of the pair of connecting and fixing member bodies 5-3b, and extends (in the radial direction R) toward the center rod 2. In this embodiment, the extension portion 5-3a is located at the other end of both of the pair of connecting and fixing member bodies 5-3b. That is, two extension portions 5-3a are formed.

[0058] The connecting and fixing member 5-3 fixes the runner main body member 5-1 and the runner auxiliary member 5-2 as follows. First, the runner main body member 5-1 and the runner auxiliary member 5-2 are connected to each other so that the main body side hole portion 5-1e and the auxiliary side hole portion 5-2e overlap (in the radial direction R). Next, the pair of connecting and fixing member bodies 5-3b are arranged on the upper part of the auxiliary lower part 5-2d along its outer circumferential surface while the other ends of the pair of connecting and fixing member bodies 5-3b are spaced apart from each other. As a result, the extension portion 5-3a of the other end portion of the pair of connecting and fixing member bodies 5-3b is inserted from the auxiliary side hole portion 5-2e side into the auxiliary side hole portion 5-2e and the main body side hole portion 5-1e. As a result, the connection between the runner main body member 5-1 and the runner auxiliary member 5-2 is fixed. Note that this is the case where the auxiliary upper part 5-2c is positioned on the outside and the main body lower part 5-1d is positioned on the inside, but when the main body lower part 5-1d is positioned on the outside and the auxiliary upper part 5-2c is positioned on the inside, the extension part 5-3a is inserted from the main body side hole part 5-1e side.

[0059] Here, to fix the ribs 8 to the runner 5, first, the rib locking protrusions of the ribs 8 are inserted into the rib locking grooves 5-1a of the runner main body member 5-1. Next, the upper end of the runner auxiliary member 5-2 (the upper part of the auxiliary upper part 5-2c and the auxiliary lower part 5-2d) is connected so as to overlap with the lower end of the runner main body member 5-1 (the main body lower part 5-1d). Then, the extension part 5-3a of the connecting and fixing member 5-3 is inserted into the auxiliary side hole part 5-2e and the main body side hole part 5-1e, thereby fixing the connection between the runner auxiliary member 5-2 and the runner main body member 5-1. As a result, the rib locking grooves 5-1a can be covered with the auxiliary upper part 5-2c. This allows the rib locking protrusions of the ribs 8 to be confined in the rib locking grooves 5-1a while maintaining a rotatable state. In other words, the rib engaging projection can be prevented from slipping out of the rib engaging groove 5-1a, and the rib 8 can be fixed to the runner 5.

[0060] On the other hand, when removing the ribs 8 from the runner 5, first, the ferrule 3 is removed from the upper wheel 4. Next, the protruding portion 3b of the ferrule 3 is pushed into the gap 5-3d formed between the elastic portion 5-3c of the connecting and fixing member 5-3 and the outer circumferential surface of the runner auxiliary member 5-2 (the portion above the auxiliary lower portion 5-2d). As a result, the elastic portion 5-3c is pushed outward in the radial direction R and separated from the runner auxiliary member 5-2, and the extension portion 5-3a is pulled out from the auxiliary side hole portion 5-2e and the main body side hole portion 5-1e. That is, the connecting and fixing member 5-3 is removed from the runner auxiliary member 5-2. This releases the connection between the runner auxiliary member 5-2 and the runner main body member 5-1. Next, the upper end of the runner auxiliary member 5-2 (the upper parts of the auxiliary upper portion 5-2c and the auxiliary lower portion 5-2d) is separated from the lower end of the runner main body member 5-1 (the lower body portion 5-1d). Then, the rib locking projection of the rib 8 is removed from the rib locking groove 5-1a of the runner main body member 5-1. When removing the connecting and fixing member 5-3 from the runner auxiliary member 5-2, another elongated member may be used instead of the ferrule tip 3, or if the elastic portion 5-3c is sufficiently large, the hand may be used.

[0061] 6 is a perspective view showing an example of the configuration of the dowels of the umbrella 1 according to the embodiment. Each of the multiple dowels 7 is provided corresponding to each of the multiple ribs 6. The dowel 7 is located midway along the ribs 6, and is a jig that connects the ribs 6 to the ribs 8 while fixing the umbrella material 9. The dowel 7 includes a dowel-side locking portion 7a, rib connecting portions 7d and 7f, and a rib connecting portion 7e.

[0062] The dowel side locking portion 7a is provided in a portion facing the umbrella fabric, and can be locked with an umbrella fabric side locking member 10 (described later) attached to the umbrella fabric 9. In this embodiment, the dowel side locking portion 7a is a female locking portion, and has a space 7c provided inside the dowel 7, and an opening 7b that penetrates from the surface of the dowel 7 to the space 7c. Therefore, the space 7c is capable of receiving the umbrella fabric side locking member 10 through the opening 7b. However, the female locking portion refers to a structure in which the female locking portion and the male locking portion are locked by some means after the male locking portion is inserted.

[0063] Here, in the opening 7b, the opening first length in the first direction X1 in FIG. 6 is longer than the opening second length in the second direction X2 perpendicular to the first direction X1. That is, the opening 7b has a shape that is long in the first direction X1. Also, in the space 7c, the space first length and the space second length in the first direction X1 and the second direction are longer than the opening first length. Note that the first direction X1 and the second direction X2 are arbitrary directions, but in this embodiment, the first direction X1 is the longitudinal direction of the dowel 7.

[0064] The rib connecting portion 7f is rotatably connected to the tip side (or ferrule side) of the rib 6. The rib connecting portion 7d is rotatably connected to the ferrule side (or tip side) of the rib 6. The rib connecting portion 7e is rotatably connected to the rib 8.

[0065] 7 is a perspective view showing a configuration example of the umbrella fabric fastening member 10 of the umbrella 1 according to the embodiment. The umbrella fabric fastening member 10 is a jig that is attached to the portion of the umbrella fabric 9 facing each of the multiple dowels 7, and fixes the umbrella fabric 9 to the dowels 7. The umbrella fabric fastening member 10 has an elongated portion 10a and a joint portion 10b.

[0066] The elongated portion 10a is connected to the joint portion 10b and can be engaged with the dowel side engaging portion 7a. In this embodiment, the elongated portion 10a is a male-type engaging portion and has an elongated cylindrical shape. Therefore, the space 7c has a shape that is long in the longitudinal direction. The longitudinal length of the elongated portion 10a is shorter than the opening first length of the opening 7b in the first direction X1 and longer than the opening second length in the second direction X2.

[0067] The joint 10b has a ring-shaped structure, and the umbrella fabric side fastening member 10 can be attached to the umbrella fabric 9 by passing a member such as a string through the inside of the ring and joining the member such as the string to the umbrella fabric 9. Examples of such attachment methods include a method of passing a thread or the like through the ring of the joint 10b and sewing it to the umbrella fabric 9, or a method of joining a member such as a string that has been passed through the ring of the joint 10b to the umbrella fabric 9, and examples of such joining methods include adhesion with an adhesive or joining with a hook-and-loop fastener.

[0068] Here, when attaching the umbrella material 9 (umbrella material side locking member 10) to the dowel 7, the longitudinal direction of the elongated portion 10a of the umbrella material side locking member 10 is made substantially parallel to the first direction X1. This allows the elongated portion 10a to be inserted into the opening 7b of the dowel 7. Next, the elongated portion 10a is inserted into the space 7c through the opening 7b. Then, the elongated portion 10a is rotated by approximately 90° to be substantially parallel to the second direction X2. This allows the elongated portion 10a to be in a state where it cannot be pulled out of the opening 7b. As a result, the dowel side locking portion 7a and the umbrella material side locking member 10 can be locked together. That is, the umbrella material 9 (umbrella material side locking member 10) can be attached to the dowel 7. To remove the umbrella material 9 (umbrella material side locking member 10) from the dowel 7, the above steps are performed in reverse.

[0069] The materials used for each component of the umbrella 1 are not particularly limited, and can be appropriately selected from known materials that can be used for umbrellas.

[0070] The umbrella of this embodiment is a disassembled umbrella having a center rod 2, a ferrule 3, a top wheel 4, a bottom wheel 5, a plurality of ribs 6, a plurality of dowels 7, a plurality of ribs 8, and an umbrella base 9. Each of the plurality of ribs 8 has a rib engaging projection at one end. The bottom wheel 5 is made up of a bottom wheel main body member 5-1, a bottom wheel auxiliary member 5-2 provided below the bottom wheel main body member 5-1, and a bottom wheel auxiliary member 5-3 provided between the bottom wheel main body member 5-1 and the bottom wheel auxiliary member 5-4. -2, and a connecting and fixing member 5-3 that fixes the connection between the runner main body member 5-1 and the runner auxiliary member 5-2, the runner main body member 5-1 having a plurality of rib engagement groove portions 5-1a provided at its upper end portion and into which the plurality of rib engagement protrusions of the plurality of ribs 8 can be inserted from below, the runner auxiliary member 5-2 can be connected so that its upper end portion overlaps with the lower end portion of the runner main body member 5-1, and the connecting and fixing member 5-3 is detachable from the runner 5.

[0071] In this case, the ribs 8 can be easily attached to and detached from the runner 5 by the following steps. That is, in the step of removing the ribs 8 from the runner 5, first, the connecting and fixing member 5-3 is removed from the runner 5. This releases the connection between the runner main body member 5-1 and the runner auxiliary member 5-2. Next, the runner auxiliary member 5-2 is moved downward to remove it from the runner main body member 5-1. This means that the rib locking grooves 5-1a of the runner 5 are no longer covered by the runner auxiliary member 5-2, so that the rib locking protrusions of the ribs 8 inserted into the rib locking grooves 5-1a can be removed downward.

[0072] On the other hand, the process of attaching the ribs 8 to the runner 5 includes first inserting the rib locking protrusions of the ribs 8 into the rib locking grooves 5-1a of the runner 5, and connecting the upper end of the runner auxiliary member 5-2 to the lower end of the runner main body member 5-1. This allows the rib locking grooves 5-1a of the runner 5 to be covered with the runner auxiliary member 5-2. Next, the connecting and fixing member 5-3 is attached to the runner 5. This fixes the connection between the runner main body member 5-1 and the runner auxiliary member 5-2. At this time, the rib locking grooves 5-1a are covered with the runner auxiliary member 5-2, so that the rib locking protrusions inserted into the rib locking grooves 5-1a are prevented from coming off downward.

[0073] In this embodiment, the runner main body member 5-1 includes a main body side hole portion 5-1e provided in its lower portion and penetrating toward the center rod 2 side, the runner auxiliary member 5-2 includes an auxiliary side hole portion 5-2e provided in its upper portion and penetrating toward the center rod 2 side, and the connecting and fixing member 5-3 may include an extension portion 5-3a that is inserted from one of the main body side hole portion 5-1e and the auxiliary side hole portion 5-2e to the other when the runner main body member 5-1 and the runner auxiliary member 5-2 are connected and the main body side hole portion 5-1e and the auxiliary side hole portion 5-2e overlap to fix the connection.

[0074] In this case, in the process of removing the ribs 8 from the runner 5, when removing the connecting and fixing member 5-3 of the runner 5, the extension portion 5-3a of the connecting and fixing member 5-3 that extended into the main body side hole portion 5-1e and the auxiliary side hole portion 5-2e is pulled out from the main body side hole portion 5-1e and the auxiliary side hole portion 5-2e. This makes it possible to easily release the connection between the runner main body member 5-1 and the runner auxiliary member 5-2. On the other hand, in the process of attaching the ribs 8 to the runner 5, after connecting the upper end portion of the runner auxiliary member 5-2 to the lower end portion of the runner main body member 5-1, when attaching the connecting and fixing member 5-3 to the runner auxiliary member 5-2, the extension portion 5-3a of the connecting and fixing member 5-3 is inserted and penetrated through the main body side hole portion 5-1e and the auxiliary side hole portion 5-2e. This makes it possible to easily fix the connection between the runner main body member 5-1 and the runner auxiliary member 5-2.

[0075] In this embodiment, the connecting and fixing member 5-3 further includes a pair of connecting and fixing member main bodies 5-3b extending along the outer peripheral surface of the wheel auxiliary member 5-2, and an elastic portion 5-3c connecting one ends of the pair of connecting and fixing member main bodies 5-3b, and the extension portion 5-3a may be located at the other end of at least one of the pair of connecting and fixing member main bodies 5-3b and extended toward the center rod 2.

[0076] In this case, in the process of removing the ribs 8 from the runner 5, by mainly deforming the elastic portion 5-3c so that the pair of connecting and fixing member main bodies 5-3b move away from each other, the extension portion 5-3a extending into the main body side hole portion 5-1e and the auxiliary side hole portion 5-2e can be more easily pulled out from the main body side hole portion 5-1e and the auxiliary side hole portion 5-2e. On the other hand, in the process of attaching the ribs 8 to the runner 5, after connecting the upper end portion of the runner auxiliary member 5-2 to the lower end portion of the runner main body member 5-1, by mainly deforming the elastic portion 5-3c so that the pair of connecting and fixing member main bodies 5-3b move away from each other, and then arranging the connecting and fixing member 5-3 on the outer circumferential surface of the runner auxiliary member 5-2, the extension portion 5-3a of the connecting and fixing member 5-3 can be more easily inserted into the main body side hole portion 5-1e and the auxiliary side hole portion 5-2e.

[0077] In this embodiment, each of the multiple ribs 6 has a rib engagement protrusion portion at one end, the ferrule 3 has a cover portion 3a and a tapered protrusion portion 3b extended from the cover portion 3a, the upper wheel 4 has a plurality of rib engagement groove portions 4a provided at the upper end portion into which the multiple rib engagement protrusion portions of the multiple ribs 6 can be inserted from above, and an insertion portion 4b provided on the upper surface of the upper end portion into which the protrusion portion 3b is inserted to connect the ferrule 3, and the elastic portion 5-3c connects one ends of the pair of connecting and fixing member main bodies 5-3b while forming a gap between it and the outer peripheral surface of the runner auxiliary member 5-2, and the protrusion portion 3b may be insertable into the gap formed between the elastic portion 5-3c and the outer peripheral surface of the runner auxiliary member 5-2.

[0078] In this case, the above-mentioned configuration is provided. Therefore, the ribs 6 can be easily attached to and detached from the wheel by the following steps. The step of removing the ribs 6 from the wheel 4 is to remove the ferrule 3 from the wheel main body. As a result, the rib locking grooves 4a of the wheel 4 are no longer covered by the lids 3a of the ferrule 3, so that the rib locking projections of the ribs 6 inserted into the rib locking grooves 4a can be removed upward.

[0079] Meanwhile, the process of attaching the ribs 6 to the upper wheel 4 involves inserting the multiple rib locking projections of the multiple ribs 6 into the multiple rib locking grooves 4a of the upper wheel 4. Then, the projections of the ferrules 3 are inserted into the joining holes of the upper wheel body to join the upper wheel 4 and the ferrules 3 together. In this way, the ferrules 4 are attached to the upper wheel 4. At this time, the multiple rib locking grooves 4a are covered with the lids 3a of the ferrules 3, so that the multiple rib locking projections inserted into the multiple rib locking grooves 4a are prevented from coming off upward.

[0080] The umbrella of this embodiment has the above-mentioned configuration. Therefore, in the process of removing the ribs 8 from the runner 5, the tip of the protruding portion 3b of the removed ferrule 3 can be inserted into the gap formed between the elastic portion 5-3c of the runner 5 and the outer circumferential surface of the runner auxiliary member 5-2, and the elastic portion 5-3c can be deformed. This allows the pair of connecting and fixing member bodies 5-3b to be deformed so as to move away from each other, and the extension portions 5-3a inserted into the main body side hole portion 5-1e and the auxiliary side hole portion 5-2e to be more easily pulled out from the main body side hole portion 5-1e and the auxiliary side hole portion 5-2e.

[0081] In this embodiment, the umbrella fabric 9 further includes an umbrella fabric side locking member 10 attached at a position opposite each of the multiple dowels 7, and each of the multiple dowels 7 has a dowel side locking portion 7a at a portion opposite the umbrella fabric side locking member 10, and the umbrella fabric 9 can be attached and detached to the ribs 6 by engaging or disengaging the dowel side locking portion 7a and the umbrella fabric side locking member 10.

[0082] In this case, the ribs 8 can be easily attached and detached to the lower wheel 5, the ribs 6 can be easily attached and detached to the upper wheel, and the umbrella material 9 can be easily attached and detached to and from the ribs 6 between the ferrule 3 and the tip by the following steps. The step of removing the umbrella material 9 from the dowel 7 of the ribs 6 is to disengage the umbrella material side fastening member 10 of the umbrella material 9 and the dowel side fastening portion 7a of the dowel 7 while fixing the dowel 7 of the ribs 6. This allows the umbrella material side fastening member 10 to be removed from the dowel side fastening portion 7a of the ribs 6. The step of attaching the umbrella material 9 to the dowel 7 of the ribs 6 is to engage the umbrella material side fastening member 10 of the umbrella material 9 and the dowel side fastening portion 7a of the dowel 7 while fixing the dowel 7 of the ribs 6. This allows the umbrella material side fastening member 10 to be attached to the dowel side fastening portion 7a of the ribs 6.

[0083] In this embodiment, the umbrella is disassembled and comprises a center rod 2, a ferrule 3, a top wheel 4, a bottom wheel 5, a number of ribs 6, a number of dowels 7, a number of ribs 8, and an umbrella fabric 9, and further comprises an umbrella fabric side locking member 10 attached to a portion of the umbrella fabric 9 facing each of the plurality of dowels 7, and each of the plurality of dowels 7 has a dowel side locking portion 7a at a portion facing the umbrella fabric 9, and the dowel side locking portion 7a and the umbrella fabric side locking member 10 can be locked or unlocked to allow the umbrella fabric 9 to be attached and detached to the ribs 6.

[0084] In this case, the umbrella fabric 9 can be easily attached to and detached from the ribs 6 between the ferrule 3 and the tip by the following steps. The step of removing the umbrella fabric 9 from the dowel 7 of the ribs 6 involves fixing the dowel 7 of the ribs 6 while disengaging the umbrella fabric side fastening member 10 of the umbrella fabric 9 from the dowel side fastening portion 7a of the dowel 7. This allows the umbrella fabric side fastening member 10 to be removed from the dowel side fastening portion 7a of the ribs 6. The step of attaching the umbrella fabric 9 to the dowel 7 of the ribs 6 involves fixing the dowel 7 of the ribs 6 while engaging the umbrella fabric side fastening member 10 of the umbrella fabric 9 with the dowel side fastening portion 7a of the dowel 7. This allows the umbrella fabric side fastening member 10 to be attached to the dowel side fastening portion 7a of the ribs 6.

[0085] In this embodiment, the dowel side fastening portion 7a may be a female fastening portion, and the umbrella fabric side fastening member 10 may be a male fastening portion. If the dowel side locking portion 7a were a male locking portion, the male part (protruding part) of the locking portion would get caught on the umbrella material 9 that contacts the dowel 7, and there is a risk of damaging or tearing the umbrella material 9. Therefore, in this umbrella, the dowel side locking portion 7a is a female locking portion. This makes it easier to attach and detach the umbrella material 9 to and from the ribs 6 while making it more difficult to damage the umbrella material 9.

[0086] In this embodiment, the dowel side engagement portion 7a has a space 7c provided inside the dowel 7 and an opening 7b penetrating from the surface of the dowel 7 into the space 7c, and in the opening 7b, an opening first length in a first direction X1 is longer than an opening second length in a second direction X2 perpendicular to the first direction X1, and in the space 7c, the space first length and the space second length in the first direction X1 and the second direction X2 are longer than the opening first length, and the umbrella fabric side engagement member 10 includes a joint 10b rotatably joined to the umbrella fabric 9 and an elongated portion 10a connected to the joint 10b, and the longitudinal length of the elongated portion 10a may be shorter than the opening first length and longer than the opening second length.

[0087] In this case, the umbrella fabric 9 can be more easily attached to and detached from the ribs 6 between the ferrule 3 and the tip by the following process. The process of removing the umbrella fabric 9 from the dowel 7 of the ribs 6 involves fixing the dowel 7 of the ribs 6, pinching the joint 10b of the umbrella fabric side fastening member 10 and rotating it by an appropriate angle to align the longitudinal direction of the elongated portion 10a of the umbrella fabric side fastening member 10 with the first direction X1 of the opening 7b of the dowel side fastening portion 7a. Then, the elongated portion 10a, whose longitudinal length is shorter than the first opening length, is pulled out from the opening 7b. This allows the umbrella fabric side fastening member 10 to be removed from the dowel side fastening portion 7a of the ribs 6. The process of attaching the umbrella fabric 9 to the dowel 7 of the rib 6 involves pinching the joint 10b of the umbrella fabric side fastening member 10 and rotating it by an appropriate angle while fixing the dowel 7 of the rib 6, so that the longitudinal direction of the elongated portion 10a of the umbrella fabric side fastening member 10 coincides with the first direction X1 of the opening 7b of the dowel side fastening portion 7a. Next, the elongated portion 10a, whose longitudinal length is shorter than the first length of the opening, is inserted into the opening 7b. Then, the joint 10b is rotated again by an appropriate angle to shift the longitudinal direction of the elongated portion 10a of the umbrella fabric side fastening member 10 from the first direction X1 of the opening 7b of the dowel side fastening portion 7a, so that the elongated portion 10a cannot be pulled out of the opening 7b. This allows the umbrella fabric side fastening member 10 to be attached to the dowel side fastening portion 7a of the rib 6.

[0088] In this embodiment, each of the plurality of ribs 8 has a rib engaging projection at one end, The runner 5 may comprise a runner main body member 5-1, a runner auxiliary member 5-2 provided below the runner main body member 5-1 and connectable so that its upper end overlaps with the lower end of the runner main body member 5-1, and a connecting and fixing member 5-3 that is detachable from the runner 5 and fixes the connection between the runner main body member 5-1 and the runner auxiliary member 5-2.

[0089] In this case, the umbrella fabric 9 can be easily attached to and detached from the ribs 6 between the ferrule 3 and the tip, and the ribs 8 can be easily attached to and detached from the runner 5 by the following steps. To remove the ribs 8 from the runner 5, first remove the connecting and fixing member 5-3 from the runner 5. This releases the connection between the runner main body and the runner auxiliary. Next, move the runner auxiliary member 5-2 downward to remove it from the runner main body member 5-1. This means that the rib locking grooves 5-1a of the runner 5 are no longer covered by the runner auxiliary member 5-2, and the rib locking protrusions of the ribs 8 inserted into the rib locking grooves 5-1a can be removed downward. On the other hand, the process of attaching the ribs 8 to the runner 5 includes first inserting the rib locking protrusions of the ribs 8 into the rib locking grooves 5-1a of the runner 5, and connecting the upper end of the runner auxiliary member 5-2 to the lower end of the runner main body member 5-1. This allows the rib locking grooves 5-1a of the runner 5 to be covered with the runner auxiliary member 5-2. Next, the connecting and fixing member 5-3 is attached to the runner 5. This fixes the connection between the runner main body member 5-1 and the runner auxiliary member 5-2. At this time, the rib locking grooves 5-1a are covered with the runner auxiliary member 5-2, so that the rib locking protrusions inserted into the rib locking grooves 5-1a are prevented from coming off downward.

[0090] In this embodiment, the umbrella may be a folding umbrella. A folding umbrella requires a process of folding from an open state and opening from a folded state before and after use, so there is a higher possibility of parts breaking than with a normal umbrella. Therefore, the umbrella of this embodiment is a folding umbrella, but as described above, the runner 5 or the dowel 7 has a specific configuration. This allows the multiple ribs 8 to be easily attached and detached to the runner 5, or allows the umbrella fabric 9 to be easily attached and detached to the ribs 6 between the ferrule 3 and the tip.
