Description

[Technical field]

[0001] The present invention relates to an umbrella, and more particularly to an umbrella having a distinctive handle provided at the end of the shaft. [Background technology]

[0002] A known conventional umbrella is that disclosed in Non-Patent Document 1. The umbrella disclosed in this document needs to be held in one hand when carrying the umbrella in a folded state. [Prior art documents] [Non-patent literature]

[0003] [Non-Patent Document 1] Internet URL (https: / / ja.wikipedia.org / wiki / %E5%82%98) Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the conventional umbrella disclosed in the above-mentioned Non-Patent Document 1, when carrying luggage in a folded state, one hand is occupied by the umbrella. Therefore, when the user operates a smartphone while holding luggage in both hands or while holding onto a strap on a bus or train, there is no suitable place to temporarily place the umbrella, and the umbrella becomes an obstacle. In particular, when it comes to smartphones, people are often seen looking at their smartphones while standing on trains, etc., and nowadays, smartphones are indispensable in any environment.

[0005] The present invention was made in consideration of such problems, and its purpose is to provide an umbrella that does not get in the way when carried in a folded state, allowing both hands to be used for other purposes. [Means for solving the problem]

[0006] In order to solve the above problems, according to the present invention, an umbrella is provided which comprises a rib portion which supports the fabric, a shaft portion which supports the rib portion so that it can be opened and closed, and a handle portion which is provided at the tip of the shaft portion, wherein the handle portion comprises a grip portion which extends along the shaft portion, an extension portion which is provided continuous with the grip portion and which extends and contracts linearly in a direction different from the extension direction of the grip portion, and a hook portion which is provided continuous with the extension portion and whose distance from the grip portion changes as the extension portion of the extension portion expands and contracts.

[0007] With this configuration, when carrying the umbrella in a folded state and both hands are full, the extendable part of the handle can be extended to hang the umbrella on the shoulder, leaving both hands free for other purposes and allowing the umbrella to be carried without getting in the way.

[0008] The present invention can be applied in various ways. The following application examples can be implemented in appropriate combination. For example, the telescopic portion may include an intermediate portion having a hollow portion with one end connected to at least one of the grip portion and the hook portion and the other end opened, and an extension portion that is accommodated in the hollow portion so as to be able to appear and disappear through the opening of the intermediate portion.

[0009] The extendable portion is extendable by connecting one end of the intermediate portion to at least one of the grip portion and the hook portion. Three extendable configurations will be described below.

[0010] In a first configuration, the telescopic section may include an intermediate section having a hollow section with one end connected to the grip section and the other end opened, and an extension section accommodated in the hollow section through the opening of the intermediate section so as to be able to appear and disappear. With this configuration, the hook section and the extension section of the handle section are integrated, and the telescopic section can be telescopically extended and retracted linearly from the opening. Therefore, the hook section of the handle section can move in the telescopic direction.

[0011] In a second configuration, the telescopic section may include an intermediate section having a hollow section with one end connected to the hook section and the other end opened, and an extension section accommodated in the hollow section through the opening of the intermediate section so as to be able to appear and disappear. With this configuration, the grip section and the extension section of the handle section are integrated, and the telescopic section can be extended and retracted linearly from the opening. Thus, the hook section and the intermediate section are integrated in the handle section and can move in the telescopic direction.

[0012] As a third configuration, the telescopic section may include an approximately half of the intermediate section, one end of which is connected to the hook section and the grip section and the other end of which is separated approximately at the center and has a hollow section with an opening, and an extension section that is accommodated in the hollow section so as to be able to appear and disappear through the opening of the intermediate section. With this configuration, the grip section of the handle section and the extension section of the approximately half of the intermediate section, and the hook section and the extension section of the approximately half of the intermediate section are connected, and the telescopic section can be linearly telescopically extended and retracted from the opening. Thus, the hook section and the approximately half of the intermediate section are integrated in the handle section and can move in the telescopic direction.

[0013] In addition, the handle portion is substantially J-shaped, and the telescopic portion may be telescopic in an arc other than a straight line, as long as it is telescopic. Note that the preferred drawings and embodiments of the present invention are described with respect to the first configuration. Since the telescopic portion is a component having substantially the same functional configuration, the duplicated description of the second and third configurations will be omitted.

[0014] In addition, a plurality of the extension parts may be provided overlapping in the radial direction, and the plurality of extension parts may be configured to protrude sequentially from the opening of the intermediate part. With this configuration, the length by which the extension part expands and contracts can be changed significantly depending on the number of the protruding extension parts, so that it is possible to deal with any thickness of the shoulder.

[0015] A magnet part may be provided at the other end of the intermediate part, and a steel part provided in the extension part may be attracted to the magnet part so that the extension part is maintained in a state where it protrudes from the intermediate part or is stored in the intermediate part. With this configuration, the extension part is maintained in a state where it protrudes from the intermediate part, so that the extension part does not inadvertently appear or disappear from the intermediate part. Furthermore, when the extension part is pulled out, it can be pulled out instantly because of its fixation with the magnet part.

[0016] Furthermore, a fixing means may be provided for fixing the extension portion to the intermediate portion at a position where the extension portion is extended and retracted to an arbitrary length.

[0017] The fixing means may include a moving knob provided on the extension portion and operable to move the extension portion in the protruding and retracting directions, a guide portion provided on the intermediate portion and guiding the movement of the moving knob, and a locking portion provided on the guide portion and locking the moving knob. With this configuration, the extension portion can be easily moved and locked by the moving knob, the guide portion, and the locking portion.

[0018] The fixing means may further comprise a rotary knob provided on the extension portion, capable of controlling the movement of the extension portion in the protruding and retracting direction and capable of restricting the movement of the extension portion by a rotating operation, and a guide portion provided on the intermediate portion for guiding the movement of the rotary knob. With this configuration, the extension portion can be easily moved and locked by the rotary knob and the guide portion.

[0019] The fixing means may be configured to include a female screw hole formed continuously from one end of the hollow portion to the opening at the other end, and a male screw formed on the outer periphery of the extension portion and screwed into the female screw hole. With this configuration, the extension portion can be extended and retracted from the middle portion and engaged simply by rotating the extension portion, making the configuration and operation of the telescopic portion easy. Effect of the Invention

[0020] According to the present invention, when carrying an umbrella in a folded state, when carrying luggage with both hands, or when you want to operate your smartphone while standing and holding on to a strap on a bus or train, the handle of the umbrella can be expanded and widened to hang the umbrella on your shoulder, allowing you to use both hands for other purposes and providing a convenient umbrella that does not get in the way. Other effects of the present invention will be described in the following description of the embodiment of the invention. [Brief description of the drawings]

[0022] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this specification and the drawings, components having substantially the same functional configurations are designated by the same reference numerals, and redundant description will be omitted.

[0023] (First embodiment) The umbrella 100 of the first embodiment will be described with reference to Fig. 1 and Fig. 2. First, the overall configuration of the umbrella 100 will be described with reference to Fig. 1 and Fig. 2. Fig. 1 is a diagram showing the configuration of the umbrella 100. Fig. 2 is a diagram for explaining the configuration when the extension section 140 is extended.

[0024] 1 and 2, the umbrella 100 comprises a rib that supports the fabric, a shaft 110 that supports the rib so that it can be opened and closed, and a handle 120 provided at the tip of the shaft 110, and the handle 120 comprises a grip 130 that extends along the shaft 110, an expandable part 140 that is connected to the grip 130 and expands and contracts linearly in a direction different from the extension direction of the grip 130, and a hook 150 that is connected to the expandable part 140 and the distance between the grip 130 and the hook 150 changes as the expandable part 140 expands and contracts. Each component will be described in detail below.

[0025] The fabric and ribs not shown in FIG. 1, and the shaft portion 110 partially shown in FIG. 1, can be configured in the same way as the fabric, ribs, and shaft of a typical umbrella, so detailed explanations will be omitted here.

[0026] (Handle part 120) 1, the handle portion 120 is configured to include a grip portion 130 extending along the shaft portion 110, an expandable portion 140 connected to the grip portion 130 and linearly expanding and contracting in a direction different from the extension direction of the grip portion 130, and a hook portion 150 connected to the expandable portion 140 and changing the distance between the grip portion 130 and the hook portion 150 due to the expansion and contraction of the expandable portion 140. The material of the handle portion 120 can be a general one, but any usable material such as a resin material or a stainless steel material may be used.

[0027] (Grip 130) Grip portion 130 is a portion that a user generally holds with his / her hand when using umbrella 100. Grip portion 130 is disposed so as to extend along shaft portion 110, as shown in Fig. 1, and is a long portion having one end connected to the tip of shaft portion 110. An expandable portion 140 extends from the other end of grip portion 130 in a substantially vertical direction and is formed integrally with grip portion 130.

[0028] (Extendable part 140) The extendable section 140 is a section that extends and retracts at the middle section 141 in order to hang the hook section 150 of the handle section 120 on the shoulder. As shown in Fig. 1 and Fig. 2, the extendable section 140 is configured to include the middle section 141, one end of which is connected to the grip section 130 and the other end of which is provided with a hollow section 141b with an opening 141a, and a first extension section 142 and a second extension section 143 that are housed in the hollow section 141b so as to be able to appear and disappear through the opening 141a of the middle section 141. The material of the extension section may be any usable material, such as a resin material or a stainless steel material.

[0029] As shown in Figs. 1 and 2, the intermediate portion 141 is an elongated portion disposed between the grip portion 130 and the hook portion 150. The intermediate portion 141 is configured with a hollow portion 141b having one end connected to the grip portion 130 and the other end with an opening 141a. The hollow portion 141b is formed from the opening 141a of the intermediate portion 141 to the vicinity of the grip portion 130, but if the intermediate portion 141 is extended in a substantially T-shape in the opposite direction to the grip portion, the stretchable portion 140 can be formed to the vicinity of the end of this extension portion. In this case, the length of the extension portion can be further extended. The shape of the intermediate portion 141 and the hollow portion 141b can be designed arbitrarily, whether it is a circular or polygonal cross section.

[0030] As shown in Figures 1 and 2, the first extension portion 142 and the second extension portion 143 are arranged so as to overlap each other in the radial direction, and the first extension portion 142 and the second extension portion 143 are configured so as to protrude sequentially from the opening 141a of the intermediate portion 141.

[0031] The first extension 142 is configured in a tubular shape having approximately the same length as the hollow portion 141b, and is slidably fitted into the hollow portion 141b. The first extension 142 is prevented from slipping out of the hollow portion 141b, and is prevented from falling off from the intermediate portion 141. The prevention of the first extension 142 from slipping out of the hollow portion 141b can be designed arbitrarily by a well-known method. For example, rubber or the like may be provided on the outer periphery of the rear end portion, which is the end portion of the first extension 142 on the grip portion 130 side, to prevent slipping out by friction.

[0032] The second extension portion 143 is configured to have substantially the same shape as the inner circumference of the first extension portion 142, is configured to be rod-shaped with substantially the same length, and is slidably fitted into the first extension portion 142. When the vicinity of the rear end portion, which is the end portion on the grip portion 130 side of the second extension portion 143, is pulled out to the vicinity of the front end portion, which is the end portion on the opening 141a side of the first extension portion 142, the first extension portion 142 is configured to be pulled out in conjunction with the second extension portion 143. Note that the extension portion of the expandable portion 140 may be composed of only the first extension portion 142.

[0033] (Hook part 150) The hook portion 150 is normally hook-shaped for hanging on the arm, etc., but when the stretchable portion 140 of the middle portion 141 is stretched and hung on the shoulder, it prevents the bag from falling off the shoulder. As shown in Figs. 1 and 2, the hook portion 150 is provided at the front end of the second extension portion 143. The hook portion 150 has at least a portion that is provided in parallel with the opposite side of the grip portion 130, and when the stretchable portion 140 is placed on the shoulder, the shoulder is pinched between the hook portion 150 and the grip portion 130, thereby restricting movement in the front-rear direction.

[0034] In this embodiment, hook portion 150 is a straight member, but it may be a curved member, and furthermore, by making it an elastically deformable member and deforming it in the extension direction of expandable portion 140, the width of the portion placed on the shoulder can be made equal to or greater than the width of expandable portion 140, or it can be made to fit the shape of the shoulder. The configuration for elastically deforming hook portion 150 can be arbitrarily designed by a well-known method, for example, by covering a bendable iron or aluminum wire core with a rubber material or the like, by combining ABS and aluminum alloy, by using a flexible pipe, or the like.

[0035] In order to prevent the stretchable portion 140 and the hook portion 150 from slipping off the shoulder, it is preferable that they are covered with a non-slip material. For example, even if the stretchable portion 140 and the hook portion 150 are not securely attached to the shoulder, the non-slip covered portion of the tip of the hook portion 150 or a part of the non-slip covered portion of the stretchable portion 140 only comes into contact with the shoulder, and this has the effect of preventing slipping off the shoulder. Examples of non-slip materials include rubber materials, silicone materials, polyurethane materials, acrylic elastic materials, non-slip elastic resin materials, etc., but are not limited to these as long as they have an anti-slip effect and can be used.

[0036] The configuration of the umbrella 100 has been described above. Next, the operation of the umbrella 100 will be described with reference to Figs. 1 and 2 again. When the umbrella 100 is put up, held in the hand, or stored, the extending portion 140 can be retracted as shown in Fig. 1. To retract the extending portion 140, the first extension portion 142 and the second extension portion 143 are stored in the hollow portion 141b of the middle portion 141. In this state, the extending portion 140 can be used as a normal handle in its shortest state.

[0037] When carrying the umbrella 100, in addition to holding the handle portion 120 in the hand, the expandable portion 140 can be extended and hung on the shoulder. When carrying the umbrella 100 hung on the shoulder, as shown in FIG. 2, first, the second extension portion 143 is pulled out from the middle portion 141 through the opening 141a. When the rear end portion of the second extension portion 143 is pulled out to the front end portion of the first extension portion 142, the first extension portion 142 is pulled out in conjunction with the second extension portion 143. In this way, the expandable portion 140 can be extended, so that the expandable portion 140 and the hook portion 150 can be hung on the shoulder.

[0038] The length to which the stretchable portion 140 is extended can be changed by adjusting the amount by which the first stretchable portion 142 and the second stretchable portion 143 are pulled out from the intermediate portion 141. The length of the stretchable portion 140 can be adjusted, for example, by pulling out only the second stretchable portion 143 from the intermediate portion 141, or by adjusting the amount by which the first stretchable portion 142 and the second stretchable portion 143 are pulled out.

[0039] (Effects of the First Embodiment) As described above, according to this embodiment, when carrying umbrella 100 in a folded state, the extension section 140 can be extended and hung over the shoulder, allowing both hands to be used for other purposes and allowing the umbrella 100 to be carried without getting in the way.

[0040] Furthermore, by making the first extension portion 142 and the second extension portion 143 retractably housed in the hollow portion 141b via the opening 141a of the middle portion 141, the extension portion 140 can be extended and retracted linearly.

[0041] In addition, the length by which the stretchable portion 140 stretches can be greatly changed depending on the number by which the first extension portion 142 and the second extension portion 143 protrude, making it possible to accommodate any thickness of the shoulder.

[0042] Furthermore, by providing a hook portion 150 at the tip of the stretchable portion 140, it is possible to prevent the stretchable portion 140 from slipping off the shoulder.

[0043] Second embodiment The umbrella 200 of the second embodiment will be described with reference to Figs. 3 and 4. Fig. 3 is a diagram showing the configuration of the umbrella 200. Fig. 4 is a diagram for explaining the configuration when the extension section 240 is extended. Note that in this embodiment, the configuration of the extension section 240 is different from that of the first embodiment, and the following description will focus on the differences from the first embodiment. The same reference symbols may be used to omit redundant description of the components that can be configured in the same way as the first embodiment, such as the shaft section 110 and the grip section 130.

[0044] As shown in Figures 3 and 4, the umbrella 200 has an expandable section 240 that is composed of an intermediate section 241 and an extension section 242. The intermediate section 241 has a magnet section 244 at the other end. The magnet section 244 has an insertion hole 244a through which the extension section 242 described below can be inserted. Since the insertion hole 244a is smaller than the opening 241a of the intermediate section 241, the edge of the magnet section 244 is exposed to the space near the periphery of the opening 241a. The magnet section 244 may be provided over the entire other end of the intermediate section 241, or may be provided over only a portion of the other end.

[0045] 3 and 4, the extension 242 is configured to have a thickness that does not contact the hollow portion 241b. A first steel portion 245, a second steel portion 246, and a third steel portion 247 that slidably fit into the hollow portion 241b are provided near the rear end, at the rear end, and at the front end of the extension 242. When the extension 242 protrudes from the middle portion 241, the first steel portion 245 is attracted to the magnet portion 244 to maintain the protruding state of the extension 242. When the extension 242 is completely accommodated in the hollow portion 241b, the third steel portion 247 is attracted to the magnet portion 244 to maintain the accommodated state.

[0046] In this embodiment, the first steel part 245 and the third steel part 247 may be magnet parts. The second steel part 246 is provided so that the part remaining in the hollow part 241b when the first steel part 245 and the magnet part 244 are attracted to each other prevents the extension part 242 from tilting, and is made of steel in this embodiment, but the material is not limited to steel.

[0047] 3 and 4, the third steel part 247 is disposed around the hook part 250 where the extension part 242 is connected. When the extension part 242 is completely housed in the hollow part 241b, the third steel part 247 is attracted to the magnet part 244, so that the hook part 250 is fixed to the tip of the middle part 241.

[0048] The configuration of the umbrella 200 has been described above. Next, the operation of the umbrella 200 will be described with reference to Figures 3 and 4 again. To retract the telescopic part 240, the extension part 242 is housed in the hollow part 241b of the middle part 241 as shown in Figure 3. At this time, the third steel part 247 of the hook part 250 is attracted to the magnet part 244 and maintains this state. Therefore, the extension part 242 does not accidentally protrude from the middle part 241.

[0049] To extend the telescopic portion 240, the extension portion 242 is pulled out from the middle portion 241 through the insertion hole 244a of the magnet portion 244 as shown in FIG. 4. At this time, the first steel portion 245 and the second steel portion 246 of the extension portion 242 slide in contact with the hollow portion 241b, so that the extension portion 242 is prevented from tilting and is smoothly pulled out. When the first steel portion 245 of the extension portion 242 abuts against the magnet portion 244, the first steel portion 245 and the magnet portion 244 are attracted to each other, and the extension portion 242 is restricted from being pulled out further. In this way, the extension portion 242 maintains the pulled-out state. By extending the telescopic portion 240 in this way, the umbrella 100 can be hung on the shoulder and both hands can be used for other purposes.

[0050] (Effects of the second embodiment) As described above, according to this embodiment, the magnet portion 244 of the intermediate portion 241 is attracted to the first steel portion 245 of the extension portion 242, and the extension portion 242 is maintained in a protruding state from the intermediate portion 241, so that the extension portion 242 does not inadvertently appear or disappear from the intermediate portion 241.

[0051] In addition, the magnet portion 244 of the middle portion 241 is attracted to the first steel portion 245 of the hook portion 250, so that the hook portion 250 does not easily come off from the middle portion 241 when the extendable portion 240 is retracted. Therefore, when the umbrella 200 is put up, the shape of the handle portion 220 can be maintained, making it easy to use.

[0052] (Third embodiment) The umbrella 300 of the third embodiment will be described with reference to Figs. 5 and 6. Fig. 5 is a diagram showing the configuration of the umbrella 300. Fig. 5 is a diagram for explaining the configuration of the extension section 340. Fig. 6 is a diagram for explaining the configuration when the extension section 340 is extended. Note that in this embodiment, the configuration of the extension section 340 is different from that of the first embodiment, and the following description will focus on the differences from the first embodiment. For parts that can be configured in the same way as the first embodiment, such as the shaft section 110 and the grip section 130, the same reference symbols may be used to omit repeated explanations.

[0053] 5 and 6, the umbrella 300 of this embodiment is provided with a fixing means 343 capable of fixing the extension part 342 to the middle part 341 at a position where the extension part 342 is extended and retracted to an arbitrary length. The fixing means 343 is provided with a moving knob 344 provided on the extension part 342 and capable of operating the movement of the extension part 342 in the extending and retracting direction, a guide part 345 provided on the middle part 341 and guiding the movement of the moving knob 344, and a locking part 346 provided on the guide part 345 and locking the moving knob 344.

[0054] As shown in Figs. 5 and 6, the movable knob 344 is provided near the rear end of the extension portion 342 and protrudes above the intermediate portion 341 via the guide portion 345. The movable knob 344 is configured to be wider than the guide portion 345, and is restricted from entering the hollow portion 341b from the guide portion 345. A locked portion 344a made of a convex leaf spring that engages with the locking portion 346 is formed between the movable knob 344 and the extension portion 342. When the upper surface of the movable knob 344 is pressed with a finger in the moving direction, the locked portion 344a is depressed when it hits the sawtooth portion of the locking portion 346, and moves past the locking portion 346 and along the guide portion 345.

[0055] 5 and 6, the guide portion 345 is an opening extending from one end of the upper portion of the intermediate portion 341 toward the other end so as to communicate with the hollow portion 341b. The moving knob 344 is disposed on the upper portion of the guide portion 345 and guides the movement of the moving knob 344 along the guide portion 345.

[0056] 5 and 6, the locking portion 346 is formed continuously in a sawtooth shape over substantially the entire length of one side of the guide portion 345. Since the locked portion 344a of the movable knob 344 can be engaged at any position of the locking portion 346, the extension portion 342 can be fixed to the intermediate portion 341 at a position where it is extended and retracted to any length.

[0057] The configuration of the umbrella 300 has been described above. Next, the operation of the umbrella 300 will be described with reference to Figs. 5 and 6 again. To retract the telescopic part 340, as shown in Fig. 5, the movable knob 344 is moved to one end of the guide part 345, and the extension part 342 is housed in the hollow part 341b of the middle part 341. At this time, the locked part 344a on the back side engages with the locking part 346, so the movement of the movable knob 344 is restricted. Therefore, the telescopic part 340 maintains its retracted state.

[0058] To extend the extendable portion 240, as shown in Fig. 6, the movable knob 344 is pressed and moved to the other end of the guide portion 345. Then, the extension portion 342 is pulled out from the opening 341a together with the movable knob 344. When the movable knob 344 is moved to any position, the locking portion 346 and the locked portion 344a are locked at that position, so that the extension portion 342 is held at any protruding position.

[0059] (Effects of the third embodiment) As described above, according to this embodiment, the fixing means 343 capable of fixing the extension portion 342 to the intermediate portion 341 at a position where the extension portion 342 is extended and retracted to any length is provided, which is convenient to use.

[0060] Furthermore, the movement and engagement of the extension portion 342 can be easily controlled by the movement knob 344, the guide portion 345, and the engagement portion 346.

[0061] (Fourth embodiment) The umbrella 400 of the fourth embodiment will be described with reference to Figs. 7 and 8. Fig. 7 shows the configuration of the umbrella 400, where (a) is a plan view, (b) is a front view, and (c) is a cross-sectional view of the vicinity of the rotating knob 444. Fig. 8 shows the configuration when the extension part 440 is extended, where (a) is a plan view, and (b) is a front view. Note that in this embodiment, the configuration of the extension part 440 is different from that of the first embodiment, and the differences from the first embodiment will be mainly described. For parts that can be configured in the same way as the first embodiment, such as the shaft part 110 and the grip part 130, the same reference symbols may be used to omit repeated explanations.

[0062] 7 and 8, the umbrella 400 of this embodiment is provided with a fixing means 443 on the extension part 440, which can fix the extension part 442 to the middle part 441 at a position where the extension part 442 is extended and retracted to an arbitrary length. The fixing means 443 is provided on the extension part 442 and is capable of operating the movement of the extension part 442 in the extending and retracting direction, and is configured to include a rotating knob 444 that can regulate the movement of the extension part 442 by rotating it, and a guide part 445 that is provided on the middle part 441 and guides the movement of the rotating knob 444.

[0063] As shown in Figs. 7 and 8, the rotating knob 444 has a male screw portion 444a protruding in the axial direction. The male screw portion 444a is inserted into the hollow portion 441b from the outside of the intermediate portion 441 via the guide portion 445, and is screwed into a female screw hole 442a provided near the rear end of the extension portion 442. The rotating knob 444 protrudes above the intermediate portion 441 and can be rotated. By rotating the rotating knob 444 in one direction, the extension portion 442, which is prevented from rotating, is pressed against the wall of the hollow portion 441b, and the movement of the extension portion 442 is restricted. In addition, by rotating the rotating knob 444 in the other direction, the extension portion 442 moves in a direction away from the wall of the hollow portion 441b.

[0064] 7 and 8, the guide portion 445 is an opening extending from one end of the upper portion of the intermediate portion 441 toward the other end so as to communicate with the hollow portion 441b. The width of the guide portion 445 is configured to be slightly larger than the diameter of the male screw portion 444a. The other end of the guide portion 445 is formed with a portion for preventing the movement of the extension portion 442.

[0065] The configuration of the umbrella 400 has been described above. Next, the operation of the umbrella 400 will be described with reference to FIG. 7 and FIG. 8 again. To retract the telescopic portion 440, as shown in FIG. 7, the rotating knob 444 is rotated in the other direction to move the extension portion 442 away from the wall of the hollow portion 441b, making the extension portion 442 movable. After that, the rotating knob 444 is moved to one end of the guide portion 445 to accommodate the extension portion 442 in the hollow portion 441b. After that, the rotating knob 444 is rotated in one direction to press the extension portion 442 against the wall of the hollow portion 441b, restricting the movement of the extension portion 442. Thus, the telescopic portion 440 is held in a retracted state.

[0066] To extend the expandable portion 440, as shown in FIG. 8, the rotating knob 444 is rotated in the other direction to move the extension portion 442 away from the wall of the hollow portion 441b, making the extension portion 442 movable. Then, the rotating knob 444 is moved to the other end of the guide portion 445. Then, the extension portion 442 is pulled out from the opening 441a together with the rotating knob 444. After moving the rotating knob 444 to an arbitrary position, it is rotated in one direction to press the extension portion 442 against the wall of the hollow portion 441b, restricting the movement of the extension portion 442. Thus, the extension portion 442 is held at an arbitrary protruding position.

[0067] (Effects of the fourth embodiment) As described above, according to this embodiment, the extension portion 442 can be easily moved and locked by the rotating knob 444 and the guide portion 445.

[0068] Fifth embodiment The umbrella 500 of the fifth embodiment will be described with reference to Figs. 9 and 10. Fig. 9 is a diagram showing the configuration of the umbrella 500. Fig. 10 is a diagram for explaining the configuration when the extension section 540 is extended. Note that in this embodiment, the configuration of the extension section 540 is different from that of the first embodiment, and the following description will focus on the differences from the first embodiment. The same reference symbols may be used to omit redundant description of the components that can be configured in the same way as the first embodiment, such as the shaft section 110 and the grip section 130.

[0069] 9 and 10, in the umbrella 500 of this embodiment, the hollow portion 541b of the middle portion 541 is configured to have a female thread. In addition, the extension portion 542 is formed to have a male thread that screws into the hollow portion 541b. A hook portion 550 is provided at the front end of the extension portion 542.

[0070] The above describes the configuration of umbrella 500. Next, the operation of umbrella 500 will be described with reference to Figures 9 and 10 again. To retract stretchable portion 540, hook portion 550 is rotated in one direction to accommodate extension portion 542 in hollow portion 541b as shown in Figure 9. Thus, stretchable portion 540 is maintained in a retracted state.

[0071] To extend the stretchable portion 540, the hook portion 550 is rotated in the other direction as shown in FIG. 10. Then, the extension portion 542 moves in a direction protruding from the middle portion 541. When the rotation of the hook portion 550 is stopped after the extension portion 542 has been moved to a desired length, the movement of the extension portion 542 is restricted. Thus, the extension portion 542 is held at a desired protruding position. In addition, the extension portion 542 may be colored red from one end to a position about 3 cm in front in order to prevent it from slipping out of the opening when protruding. The colored portion makes it easier to grasp the position of the remaining extension portion 542.

[0072] Furthermore, at least the middle portion 541 may be made of a transparent material. By being able to see the extension portion 542, the position of the extension portion 542 can be easily grasped. Examples of the transparent material include polyethylene, silicone, FRP, polyurethane, polycarbonate, etc., but any usable material may be used, and there is no particular limitation. Other portions may also be made of a transparent material if usable. The above points are similar to other embodiments.

[0073] (Effects of the Fifth Embodiment) As described above, according to this embodiment, extension portion 542 can be caused to protrude from and be engaged with intermediate portion 541 simply by rotating extension portion 542, and therefore extension portion 540 is easy to configure and operate.

[0074] Although the preferred embodiment of the present invention has been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to such an example. It is clear that a person skilled in the art can think of various modified or altered examples within the scope of the claims, and it is understood that such examples also naturally belong to the technical scope of the present invention.

[0075] For example, in the first embodiment, the expandable portion 140 is configured to expand and contract in a direction approximately perpendicular to the circular direction of the grip portion 130, but the present invention is not limited to this example. Any design may be used as long as the expandable portion expands and contracts in a direction different from the extension direction of the grip portion. For example, the expandable portion may expand and contract diagonally downward or diagonally upward with respect to the extension direction of the grip portion. The same applies to the second to fifth embodiments.

[0076] In the first embodiment, the first extension portion 142 and the second extension portion 143 of the stretchable portion 140 are capable of appearing and disappearing from the hollow portion 141b of the middle portion 141, but the present invention is not limited to this example. For example, the extension portions may be disposed on the outer periphery of the middle portion and may appear and disappear from the outer periphery of the middle portion. The same applies to the second to fifth embodiments.

[0077] The above-described embodiments, applications, modifications, and the like can be implemented in any combination. [Explanation of symbols]
