DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] An umbrella U according to an embodiment of the present invention will be described with reference to Figs. For the sake of convenience, when explaining the directions, the umbrella U is used as a reference in use, with the ferrule 8 side shown in Fig. 1 being the top and the handle 9 side being the bottom. Also, parts with the same configuration are given the same reference numerals and their explanations are omitted.

[0012] <Overall structure of the umbrella> As shown in FIG. 1, the umbrella U is mainly composed of a center pole 1, a top wheel 2, a bottom wheel 3, a plurality of (e.g., eight) ribs 4, a plurality of (e.g., eight) ribs 5, a umbrella cloth 6, a tip 7, a ferrule 8, and a handle 9. In FIG. 1, a part of the umbrella cloth 6 is omitted so that the top wheel 2 and the bottom wheel 3 can be seen. The center pole 1, the top wheel 2, the bottom wheel 3, the ribs 4, the ribs 5, the umbrella cloth 6, the tip 7, the ferrule 8, and the handle 9 are made of resin (synthetic resin), and can be separated (disassembled) when the umbrella U is disposed of. In this way, the components used in the umbrella U can be easily assembled and easily disassembled for recycling. In addition, the center rod 1, upper wheel 2, lower wheel 3, tip 7 and handle 9 are made from environmentally friendly bioplastics (biomass plastic (non-biodegradable), biodegradable plastic (derived from fossil resources), biomass plastic and biodegradable plastic, etc.). The number of ribs 4 and ribs 5 may be changed as appropriate. In the following, an example in which there are eight ribs 4 and ribs 5 will be described.

[0013] <Middle pole> The center rod 1 shown in Figure 1 is a core rod that is placed on the axial center line of the umbrella U. The center rod 1 has a two-layer structure, with the inner layer made of glass fiber or carbon fiber and the outer layer made of resin. A top wheel 2 is attached to the upper end of the center rod 1, and a bottom wheel 3 is attached to the center of the center rod 1 so that it can slide freely. A handle 9 is attached to the lower end of the center rod 1.

[0014] <Upper Wheel> As shown in Figure 1 or 2, a rib 4 and a ferrule 8 are attached to the upper wheel 2. The upper wheel 2 is made of a tubular member, fitted onto the upper end of the center rod 1, and fixed to the center rod 1 by a pin 20 that passes through the upper wheel 2 and the center rod 1. As shown in Figure 2, the upper wheel 2 is integrally formed with a flange portion 21, a rib support portion 22, an upper tube portion 23, an insertion portion 24, a cylindrical portion 25, and a male thread portion 26.

[0015] <Flange> As shown in Fig. 3, the flange 21 is a portion that supports the periphery of the screw insertion hole 6a formed in the center of the umbrella cloth 6 and the top paper 61 from below. The flange 21 is formed in a circular flat plate shape in a plan view. A rib support portion 22 is formed below the flange 21, and a male screw portion 26 is formed above the flange 21.

[0016] <Main rib support part> 2, the rib support part 22 is a part that supports the multiple ribs 4 in a removable and rotatable manner. The rib support part 22 is formed in a substantially circular thick plate shape in a plan view. The rib support part 22 includes a circular thick plate part 22a, an engagement groove 22b, and a shaft support part 22c.

[0017] 2 to 5, the circular thick plate portion 22a is a thick, flat plate-like portion having a circular shape in a plan view, which is formed below the flange portion 21. An engagement groove 22b and a shaft support portion 22c are formed in the circular thick plate portion 22a.

[0018] As shown in Fig. 2, the engagement grooves 22b are grooves formed on the outer peripheral surface of the circular thick plate portion 22a, and extend in the vertical direction (see Figs. 5 and 8). The upper ends of the engagement grooves 22b are closed by the flange portion 21. On the other hand, the lower ends of the engagement grooves 22b are open. As shown in Fig. 8, the number of engagement grooves 22b is the same as the number of ribs 4 (eight), and the eight engagement grooves 22b are formed radially on the outer periphery of the upper wheel 2 in a plan view.

[0019] 2, one end of the rib 4 is connected to the pivot support portion 22c. The pivot support portion 22c is made of a horizontal shaft formed in the upper portion of each of the engagement grooves 22b.

[0020] <Upper cylinder part> 2, the upper tube portion 23 is formed in a cylindrical shape, and is attached to the upper end portion of the center rod 1. The upper tube portion 23 is formed on the lower side of the rib support portion 22. In other words, the upper tube portion 23 extends from the lower surface of the rib support portion 22 toward the lower wheel 3.

[0021] <Insertion part and engagement part> 6A and 6B, the insertion portion 24 is a portion that is inserted into the upper end of the lower wheel 3, and is made of a cylinder with a smaller diameter than the outer diameter of the upper cylindrical portion 23. The insertion portion 24 is formed on the lower side of the upper cylindrical portion 23. An engaging portion 2a is protruded from the lower end of the insertion portion 24 and is formed so as to be able to engage and disengage with the upper end of the lower wheel 3 (an engaged portion 3a, which will be described later). The engagement portion 2a comprises a protrusion 24a formed in a ring shape on the outer periphery of the insertion portion 24, a ring-shaped locking groove 24b provided adjacent to the upper side of the protrusion 24a, and a pair of tongue-shaped protrusions 24c (see Figure 2) protruding downward from the lower end of the cylindrical insertion portion 24. The convex portion 24a is a protrusion that engages with the concave portion 31a to maintain the umbrella U in the open position when the lower wheel 3 is pushed upward (in the direction of the arrow a) to open the umbrella U (see Figure 1), as shown in Figure 6B. The locking groove 24b is an annular groove that engages with the locking protrusion 31c to maintain the umbrella U in the open position when the lower roller 3 is pushed upward (in the direction of arrow a) to open the umbrella U (see Figure 1). The protruding piece 24c is a guide that makes it easier for the lower roller 3 to fit loosely into the small diameter insertion portion 24 when the lower roller 3 is pushed upward (in the direction of arrow a) to open the umbrella U.

[0022] <Cylindrical part> As shown in Fig. 3, the cylindrical portion 25 is a cylindrical portion that protrudes upward from the flange portion 21. The cylindrical portion 25 is inserted into the screw insertion hole 6a of the umbrella cloth 6, the screw insertion hole 61a of the top paper 61, the screw insertion hole 83a of the seal portion 83 of the ferrule 8, and the screw insertion hole 81b of the ferrule body 81. The cylindrical portion 25 has a center rod insertion hole (not shown) into which the upper end of the center rod 1 is inserted. A pin installation hole 25a that leads to the center rod insertion hole (not shown) is formed in the cylindrical portion 25. A pin 20 for fixing the center rod 1 to the upper wheel 2 is fitted into the pin installation hole 25a.

[0023] <Pin> As shown in Fig. 3, the pin 20 is a fixing device that removably fixes the upper wheel 2 to the center rod 1. The pin 20 is made of, for example, a rod-shaped member made of resin. The pin 20 installed in the pin installation hole 25a can be pushed out of the upper wheel 2 by pressing it with a tool or the like. By pushing the pin 20 out of the upper wheel 2, the upper wheel 2 can be removed from the center rod 1 and disassembled.

[0024] <Male thread> The male threaded portion 26 is formed to protrude upward from the flange portion 21 via the cylindrical portion 25. The ferrule 8 is attached to the male threaded portion 26.

[0025] <<Lower Wheel>> As shown in Figure 1 or 2, a rib 5 is attached to the lower wheel 3. The lower wheel 3 is composed of a tubular member slidably fitted on the center rod 1 between the upper wheel 2 and the handle 9. As shown in Figure 2, the lower wheel 3 is formed with a lower tube portion 31, a rib support portion 32, a gripping tube portion 33, and a retraction prevention portion 34.

[0026] <Lower cylinder part> As shown in Fig. 2, the lower tube portion 31 is a portion for detachably connecting the lower wheel 3 to the upper wheel 2, and is formed on the upper side of the rib support portion 32. That is, the lower tube portion 31 extends from the upper surface of the rib support portion 32 toward the upper wheel 2. As shown in Fig. 6A and Fig. 6B, the lower tube portion 31 is formed in a cylindrical shape, and an engaged portion 3a is formed on the inside of the upper end portion of the lower tube portion 31 with which the engaging portion 2a of the upper wheel 2 engages to hold the umbrella U in an open state. When the engaging portion 2a of the upper turntable 2 engages with the engaged portion 3a of the lower turntable 3, the length L1 from the lower surface of the rib support portion 22 to the upper surface of the rib support portion 32 shown in Fig. 1 is, for example, 12 cm. The length L1 is the sum of the length L11 from the lower surface of the rib support portion 22 to the lower end of the upper tube portion 23 and the length L12 from the upper surface of the rib support portion 32 to the upper end of the lower tube portion 31 shown in Fig. 2. The length L2 (see FIG. 1) from the center of the hooking portion 52b of the rib 5 to the center of the hooking portion 53b is, for example, 27 cm. As shown in FIG. 1, when the umbrella U is open, the rib opening angle θ3 from the outer circumferential surface of the lower tube portion 31 to the rib 5 with the rib support portion 32 as the center is, for example, 70 degrees.

[0027] 6A and 6B, the engaged portion 3a is a portion that engages with the engaging portion 2a of the insertion portion 24 when the lower roller 3 is pushed up toward the upper roller 2 to open the umbrella U. The engaged portion 3a includes a recess (annular groove) 31a, a large diameter portion 31b, a locking protrusion 31c, a vertical groove 31d, a protruding piece engaging portion 31e, and a rotation suppressing portion 31f. The recess 31a is a portion with which the protrusion 24a of the upper wheel 2 is detachably engaged. The recess 31a is composed of a groove formed in an annular shape on the inner wall of the lower tube portion 31. On the upper side of the recess 31a, a large diameter portion 31b, a locking protrusion 31c, and multiple vertical grooves 31d are formed. The large diameter portion 31b is the portion into which the insertion portion 24 of the upper wheel 2 is first inserted when the lower wheel 3 is pushed up toward the upper wheel 2 to open the umbrella U. The large diameter portion 31b is formed to have a larger diameter than the recess 31a and the protruding piece engaging portion 31e so that the engaging portion 2a can easily fit into the engaged portion 3a when the lower wheel 3 is pushed up toward the upper wheel 2. The large diameter portion 31b is formed on the inner edge of the opening of the lower tube portion 31. The locking protrusion 31c is an annular protrusion that engages with the locking groove 24b with a snap sound when the lower wheel 3 is pushed up toward the upper wheel 2 and the umbrella U is opened. The vertical groove 31d is a notched groove that allows adjustment of the pressing force when the convex portion 24a (engaging portion 2a) is pushed into the large diameter portion 31b to engage it, and the pulling force when it is released, and also allows the opening of the lower tube portion 31 to be easily elastically deformed so that it can be attached and detached with a relatively small force. A plurality of vertical grooves 31d (for example, four grooves) are formed at appropriate intervals in the circumferential direction along the axial center line of the lower wheel 3, from the opening end of the lower tube portion 31 to the axial center of the large diameter portion 31b. According to this configuration, by forming the vertical groove 31d on the engaged portion 3a (concave portion 31a), the pushing force and pulling force required to engage with and disengage from the engaging portion 2a (convex portion 24a) can be reduced, thereby improving durability and making the engaging portion less susceptible to wear. The protruding piece engaging portion 31e is the portion into which the protruding piece 24c fits when the lower wheel 3 is pushed up toward the upper wheel 2 and the engaged portion 3a is fitted onto the engaging portion 2a. 6A and 6B, a rotation suppressing portion 31f (see FIG. 18) that suppresses rotation of the protruding piece 24c (see FIG. 2 and FIG. 17) of the upper wheel 2 is formed on the inner peripheral surface of the lower cylinder portion 31 of the lower wheel 3. The rotation suppressing portion 31f is made of a plurality of protrusions that, when the upper wheel 2 rotates relative to the lower wheel 3, the protruding piece 24c comes into contact with the rotation suppressing portion 31f to suppress rotation of the upper wheel 2.

[0028] By moving the lower wheel 3 upward along the center rod 1 and engaging the engaged portion 3a (concave portion 31a) with the engaging portion 2a (convex portion 24a) of the upper wheel 2, the umbrella U can be maintained in the open position as shown in Figure 1. In addition, when the umbrella U is in an open state, the lower wheel 3 can be moved downward along the center rod 1 to disengage the engaged portion 3a (concave portion 31a) from the engaging portion 2a (convex portion 24a) of the upper wheel 2, thereby closing the umbrella U.

[0029] <Bone support part> As shown in Fig. 2, the rib support portion 32 is a portion that removably and rotatably supports a plurality of ribs 5. The rib support portion 32 has a large diameter portion 32d of a substantially cylindrical shape formed on the lower side of the lower tube portion 31, and a small diameter portion 32e of a substantially cylindrical shape formed on the lower side of the large diameter portion 32d. An engagement groove 32a is formed in the small diameter portion 32e. A holding portion 32c is formed in the large diameter portion 32d. A pivot portion 32b is formed at the boundary between the large diameter portion 32d and the small diameter portion 32e.

[0030] The engagement groove 32a is a groove formed on the outer peripheral surface of the small diameter portion 32e, and extends in the vertical direction. The lower end of the engagement groove 32a is closed by the upper end of the gripping tube portion 33. Meanwhile, the upper end of the engagement groove 32a communicates with the holding portion 32c. As shown in Fig. 9, the number of the engagement grooves 32a is the same as the number of the ribs 5 (eight), and the eight engagement grooves 32a are formed radially on the outer peripheral portion of the lower wheel 3 in a plan view.

[0031] 2, one end of the rib 5 is connected to the pivot support portion 32b. The pivot support portion 32b is formed of a horizontal shaft.

[0032] As shown in Figs. 2 and 9, the holding portion 32c is a groove formed in the large diameter portion 32d and extends in the vertical direction. The lower end of the holding portion 32c is connected to the engagement groove 32a. On the other hand, the upper end of the holding portion 32c is open. The holding portion 32c can hold one end of the rib 5 (the lower turn engaging portion 53c described later). As shown in Figs. 4 and 9, the side wall of the holding portion 32c is formed in an arc shape in a plan view. The groove width of the holding portion 32c is maximum above the pivot support portion 32b. The opening width of the holding portion 32c on the outer peripheral surface of the large diameter portion 32d is smaller than the maximum groove width of the holding portion 32c and is formed to be equal to the outer diameter of the lower turn engaging portion 53c of the rib 5.

[0033] <Grip cylinder part> As shown in Fig. 1, the gripping tube 33 is a part used as a handle when opening and closing the umbrella U. That is, when the runner 3 is raised to open the umbrella U, and when the runner 3 is lowered to close the umbrella U, the gripping tube 33 is gripped to operate the runner 3. As shown in Figs. 2, 3, and 4, the gripping tube 33 is formed on the lower side of the rib support part 32. The gripping tube 33 is formed in a cylindrical shape, but is gradually tapered from the upper and lower ends to the center, making it easy to hold when raising and lowering the runner 3.

[0034] <Retraction prevention section> The pull-in prevention part 34 is a part for eliminating the gap between the center pole 1 and the lower wheel 3 when opening or closing the umbrella U, to prevent fingers from being pulled into the gap and being pinched between the center pole 1 and the lower wheel 3. The pull-in prevention part 34 is integrally formed of resin at the lower end of the gripping tube part 33. The pull-in prevention part 34 may be formed as a ring-shaped buffer member made of rubber or soft resin separately from the lower wheel 3 and attached to the lower end of the gripping tube part 33.

[0035] ≪Main bone≫ As shown in Fig. 1, the ribs 4 are rib members for stretching the umbrella cloth 6. The base end of the ribs 4 is supported on the upper part of the upper turntable 2. The ribs 4 are made of roughly rod-shaped members, which approach the center pole 1 when the umbrella U is closed and radiate out from the upper end of the center pole 1 when the umbrella U is opened. As shown in Fig. 2, the ribs 4 include a rib body 41, a center dowel 42, a top turntable hook 43, and a tip 7.

[0036] <Main rib body> As shown in Figure 1, the rib body 41 is a member that supports the umbrella cloth 6 from below when the umbrella U is opened. The rib body 41 is made of a rod-shaped member made of resin, glass fiber, or carbon. As shown in Figures 2 and 11, a top roller hanging hook 43 is attached to the base end of the rib body 41. A middle dowel 42 is attached to the center of the rib body 41, and a tip 7 is attached to the tip of the rib body 41.

[0037] <Middle dowel> 2, 11 or 12, the central dowel 42 is a member disposed at the connection portion between the rib 4 and the rib 5. The central dowel 42 is made of a resin member in which a cylindrical portion 42a, a hook shaft support portion 42b and a support piece 42c are integrally formed. The central dowel 42 can be removed from the rib body 41 and recycled.

[0038] As shown in FIGS. 11 and 12, the tubular portion 42a is a tubular portion that is fitted onto the rib main body 41. As shown in FIG. The hook shaft support portion 42b is a portion that rotatably and detachably supports the center dowel retaining hook 52 provided on the frame 5. The hook shaft support portion 42b is composed of a horizontal shaft that is installed between the two support pieces 42c. The support piece 42c protrudes toward the center rod 1 from the outer circumferential surface of the cylindrical portion 42a.

[0039] <Upper wheel hanging hook> As shown in Figure 2 or 11, the upper lath hook 43 is a member for connecting the rib 4 to the rib support part 22 of the upper lath 2. The upper lath hook 43 has a plate-shaped part 43a, a hooking part 43b, and a rib body connecting part 43c. The plate-shaped part 43a, the hooking part 43b, and the rib body connecting part 43c are integrally formed from resin. The upper lath hook 43 can be removed from the rib body 41 and recycled.

[0040] As shown in FIG. 2, FIG. 5 or FIG. 8, the plate-like portion 43a is a portion to be inserted into the engagement groove 22b. The hook 43b is a hook that is substantially C-shaped in side view and is rotatably hooked to the pivot 22c. The hook 43b hooked to the pivot 22c can rotate up and down. When the rib 4 rotates up and down, it rotates up and down around the pivot 22c, and the plate-shaped portion 43a is guided by the engagement groove 22b, which is a vertical groove, so that it is difficult for the hook 43b to rotate left and right. The angle θ1 at which the hook 43b can rotate is the angle from the position where the upper roller hook 43 abuts against the lower surface of the flange 21 to the position where it is along the upper tube portion 23, and is about 90 degrees. The rib main body connecting portion 43c is a cylindrical portion into which the end portion of the rib main body 41 is inserted.

[0041] ≪Bone≫ As shown in FIG. 1, the ribs 5 are bone members for connecting the center rod 1 and the ribs 4. The ribs 5 are arranged to extend radially from the lower wheel 3. The base end of the ribs 5 is connected to the rib support part 32 of the lower wheel 3, and the tip end of the ribs 5 is connected to the center dowel 42 of the ribs 4. The ribs 5 are made of a substantially rod-shaped member, and when the umbrella U is closed (when the lower wheel 3 is moved toward the handle 9), the ribs 4 approach the center rod 1 while drawing the ribs 4 toward it, and when the umbrella U is opened (when the lower wheel 3 is moved toward the ferrule 8), the ribs 5 extend radially from the center rod 1 and unfold the ribs 4. As shown in FIG. 2, the ribs 5 include a rib body 51, a center dowel hook 52 provided at the tip of the rib body 51, and a lower wheel hook 53 provided at the base end of the rib body 51.

[0042] <Bone body> 1 and 2, the rib body 51 is a member that supports the ribs 4 from below when the umbrella U is opened. The rib body 51 is made of resin, glass fiber, or carbon. A center dowel hook 52 is attached to the tip of the rib body 51, and a lower roller hook 53 is attached to the base end of the rib body 51.

[0043] <Medium dowel hook> The center dowel hook 52 is a member for connecting the rib 5 to the center dowel 42 of the rib 4. The center dowel hook 52 has a plate-shaped portion 52a, a hooking portion 52b, and a rib body connecting portion 52c. The plate-shaped portion 52a, the hooking portion 52b, and the rib body connecting portion 52c are integrally formed of resin. The center dowel hook 52 can be removed from the rib body 51 and recycled.

[0044] As shown in FIG. 2, FIG. 11 or FIG. 12, the plate-shaped portion 52a is a portion that is inserted between the pair of support pieces 42c. The hook portion 52b is a hook that is substantially C-shaped in side view and is rotatably hooked to the hook shaft support portion 42b. The hook portion 52b hooked to the hook shaft support portion 42b is rotatable in the vertical direction. When the frame 5 rotates up and down, it rotates up and down around the hook shaft support portion 42b, and the plate-shaped portion 53a is guided by the two support pieces 42c, so that it is difficult for the frame 5 to rotate left and right. The bone support body connecting portion 52c is a cylindrical portion into which the end portion of the bone support body 51 is inserted.

[0045] <Lower wheel hanging hook> The lower rung hook 53 is a member for rotatably connecting the frame 5 to the frame support portion 32 of the lower rung 3. Like the upper rung hook 43 and the center dowel hook 52, the lower rung hook 53 has a plate-shaped portion 53a, a hook portion 53b, and a lower rung engagement portion 53c. The plate-shaped portion 53a, the hook portion 53b, and the lower rung engagement portion 53c are integrally formed from resin. The lower rung hook 53 can be removed from the frame body 51 and recycled.

[0046] As shown in FIG. 2, FIG. 5 or FIG. 8, the plate-like portion 53a is a portion to be inserted into the engagement groove 32a. The hook 53b is a hook that is substantially C-shaped in side view and is rotatably hooked to the pivot 32b. The hook 53b hooked to the pivot 32b can rotate up and down. When the rib 5 rotates up and down, it rotates up and down around the pivot 32b, and the plate-shaped portion 53a is guided by the engagement groove 32a, which is a vertical groove, so that it is difficult for the hook 53b to rotate left and right. The angle θ2 at which the hook 53b can rotate is the angle from the position where the lower turn hook 53 of the rib 5 is along the lower tube portion 31 to the position where it faces diagonally upward from the rib support portion 32, and is about 70 degrees.

[0047] The lower wheel engaging portion 53c is a portion that fits into the holding portion 32c of the lower wheel 3 when the umbrella U is closed. The lower wheel engaging portion 53c has a cylindrical shape. An end of the rib body 51 is inserted into the lower wheel engaging portion 53c. As shown in FIG. 2, when the umbrella U is closed and the rib 5 is aligned with the lower tube portion 31, the lower wheel engaging portion 53c fits into the holding portion 32c and is held by the holding portion 32c, thereby maintaining the umbrella U in a closed state.

[0048] When the umbrella U is changed from a closed state to an open state (when the runner 3 is moved toward the ferrule 8), the runner engagement portion 53c is disengaged from the holding portion 32c. In other words, the runner engagement portion 53c is detachable from the holding portion 32c.

[0049] ≪Umbrella cloth≫ As shown in Fig. 1, the umbrella cloth 6 is a sheet member for protection from rain, sun, etc. The umbrella cloth 6 is placed on the ribs 4 and sewn to the ribs 4 at appropriate positions. The umbrella cloth 6 of this embodiment is formed in an octagonal shape in a plan view to correspond to the eight ribs 4. Tips 7 (see Fig. 11) are sewn to each of the corners of the outer periphery of the octagonal umbrella cloth 6. The umbrella cloth 6 is formed from environmentally friendly recycled polyester fabric (recycled PET bottle fabric).

[0050] ≪Top of dew≫ As shown in Figures 1, 2 and 11, the tip 7 is a member for holding the outer periphery of the umbrella cloth 6 to the tip of the ribs 4. The tip 7 is made of a resin cap having a cylindrical shape with a bottom, and the tip is formed into a semi-spherical shape to give it a rounded shape.

[0051] ≪Stonestone≫ As shown in Fig. 3, the ferrule 8 is a member attached to the tip of the umbrella U. The ferrule 8 comprises a ferrule body 81, an anti-slip portion 82, and a seal portion 83. The ferrule body 81 is made of, for example, resin, and the anti-slip portion 82 and the seal portion 83 are made of, for example, silicone or rubber.

[0052] <Feet body> The ferrule body 81 is a portion that forms the framework of the ferrule 8. The ferrule body 81 is formed with a female thread portion 81a, a screw insertion hole 81b, a slip-stop fitting portion 81c, and a seal fitting portion 81d. The female threaded portion 81a is a threaded portion that screws into the male threaded portion 26 of the upper wheel 2 to removably fix the ferrule 8 to the upper wheel 2. The screw insertion hole 81b is the portion into which the cylindrical portion 25 of the upper wheel 2 is inserted. The non-slip fitting portion 81c is a portion to which the non-slip portion 82 is fitted. The seal fitting portion 81d is a portion into which the seal portion 83 is fitted.

[0053] <Anti-slip part> The anti-slip portion 82 is disposed at the upper end of the umbrella U, and is a portion that functions as an anti-slip and cushioning material when the umbrella U in a closed state is struck against the ground. The anti-slip portion 82 has a spherical portion 82a that is disposed in a bulging state from the upper end of the ferrule body 81, and a fitting portion 82b that fits into the anti-slip fitting portion 81c. The anti-slip portion 82 is disposed at the upper end of the ferrule body 81. In this way, the tip of the umbrella U is rounded by the spherical portion 82a of the anti-slip portion 82 using a soft material such as silicon, so that it is not dangerous, has an anti-slip function, and does not rust.

[0054] <Sealing section> The seal part 83 is a part that functions to prevent rainwater from leaking under the umbrella cloth 6 through the screw insertion hole 61a of the top paper 61 and the screw insertion hole 6a of the umbrella cloth 6. In addition, since the seal part 83 is made of silicone or rubber, it also functions as a member to prevent the top paper 61 and umbrella cloth 6, which are arranged below the seal part 83, from slipping. The seal part 83 is located at the lower end of the ferrule body 81.

[0055] ≪Handle≫ The handle 9 shown in Fig. 1 is the part that a user holds when using the umbrella U. The handle 9 is made of a resin handle fitted onto the lower end of the center rod 1. The upper end of the handle 9 is formed with a female threaded portion (not shown) that screws into a male threaded portion (not shown) formed on the lower end of the center rod 1, and the handle 9 is fixed to the center rod 1 by screwing the female threaded portion into the male threaded portion of the center rod 1.

[0056] [Effect] Next, a method of assembling the umbrella U and its functions and effects will be described with reference to Figs.

[0057] When assembling umbrella U, as shown in Fig. 1, the male threaded portion (not shown) at the lower end of center rod 1 is screwed into the female threaded portion (not shown) at the upper end of handle 9. Center rod 1 is also inserted into lower wheel 3 and upper wheel 2. The upper end of center rod 1 is inserted into cylindrical portion 25 of upper wheel 2. Then, as shown in Fig. 3, pin 20 is inserted into pin installation hole 25a of cylindrical portion 25 to fix upper wheel 2 to center rod 1.

[0058] 2, the tubular portion 42a of the middle dowel 42 is fitted into the middle portion of the rib body 41, and the rib body connecting portion 43c of the upper turn hook 43 is fitted into the base end (upper end) of the rib body 41. Also, the rib body connecting portion 52c of the middle dowel hook 52 is fitted into the tip end (upper end) of the rib body 51 of the rib 5, and the lower turn engaging portion 53c of the lower turn hook 53 is fitted into the base end (lower end) of the rib body 51.

[0059] Next, the ribs 5 are connected to the ribs 4. Specifically, the hook portion 52b of the center dowel hooking hook 52 is hooked to the hook shaft support portion 42b of the center dowel 42. The ribs 4 and the ribs 5 can be attached with a single touch, making the attachment work easy and quick.

[0060] Next, the ribs 4 are connected to the upper turntable 2. Specifically, with the ribs 4 approximately perpendicular to the upper tube portion 23 (with the notched portion of the hook portion 43b of the upper turntable hooking hook 43 facing upward), the hook portion 43b is positioned below the pivot portion 22c of the upper turntable 2, and the pivot portion 22c is pushed into the hole of the hook portion 43b, thereby hooking the hook portion 43b to the pivot portion 22c. In the same manner, the hook portions 43b of the eight ribs 4 are hooked to the pivot portions 22c of the upper turntable 2. The ribs 4 can be attached to the upper turntable 2 with a single touch, making the installation easy and quick.

[0061] Next, the ribs 5 are connected to the lower wheel 3. With the ribs 5 approximately perpendicular to the lower tube portion 31 (with the notched portions of the hooks 53b of the lower wheel hooking hooks 53 facing downward), the hooks 53b are positioned above the pivot portions 32b of the upper wheel 2, and the pivot portions 32b are pressed into the holes in the hooks 53b to hook them to the pivot portions 32b. In the same manner, the hooks 53b of the eight ribs 5 are hooked to the pivot portions 32b of the lower wheel 3. The ribs 5 can be attached to the lower wheel 3 with a single touch, making the installation process easy and allowing for quick assembly.

[0062] Next, the cylindrical portion 25 is inserted through the screw insertion hole 6a of the umbrella cloth 6 and the screw insertion hole 61a of the top paper 61. After that, the male threaded portion 26 of the upper turntable 2 is screwed into the female threaded portion 81a of the ferrule 8, and the umbrella cloth 6 and the top paper 61 are sandwiched between the flange portion 21 of the upper turntable 2 and the seal portion 83 of the ferrule 8. Then, the seal portion 83 made of an elastic material comes into close contact with the upper surface of the top paper 61, and the periphery of the screw insertion hole 61a of the top paper 61 and the periphery of the screw insertion hole 6a of the umbrella cloth 6 are pressed against the upper surface of the flange portion 21. This makes it possible to prevent rainwater from leaking from the screw insertion hole 6a of the umbrella cloth 6 to the underside of the umbrella cloth 6.

[0063] Next, as shown in Figure 11, the umbrella cloth 6 is sewn to the ribs 4, and the tips 7 sewn to the eight corners of the outer periphery of the umbrella cloth 6 are fitted into the tips of the rib body 41. This completes the assembly of the umbrella U. Since the umbrella U does not have a retractable rod, spring material, wire, etc., the number of parts and the assembly man-hours are simpler than those of conventional umbrellas. In other words, the umbrella U can be easily assembled in a short time, which reduces costs.

[0064] Furthermore, when opening the umbrella U, as shown in Figure 2 or Figures 6A and 6B, the lower wheel 3 is pushed upward to engage the engaged portion 3a (recess 31a) with the engaging portion 2a (protrusion 24a) of the upper wheel 2, thereby maintaining the umbrella U in an open state. When the engaged portion 3a (recess 31a) engages with the engaging portion 2a (protrusion 24a), a sound is generated, allowing one to confirm that the umbrella U is maintained in an open state.

[0065] To close the umbrella U, as shown in Fig. 2 or 6A and 6B, the lower wheel 3 is pulled downward to separate the engaged portion 3a (recess 31a) from the engaging portion 2a (protrusion 24a) of the upper wheel 2, thereby closing the umbrella U. Furthermore, by lowering the lower wheel 3 downward, as shown in Fig. 2 or 9, the lower wheel engaging portion 53c of the rib 5 is pushed into the holding portion 32c of the lower wheel 3 to engage it, thereby maintaining the state in which the rib 5 is aligned with the center rod 1 (i.e., the umbrella U is closed). When the lower wheel engaging portion 53c is pushed into the holding portion 32c, a sound is generated, so it can be confirmed that the umbrella U is maintained in the closed state.

[0066] Furthermore, when disposing of or repairing the umbrella U, the assembled umbrella U can be easily disassembled. When disassembling the umbrella U, the tip 7 shown in Fig. 11 is removed from the rib body 11, the threads connecting the ribs 4 and the umbrella cloth 6 are removed, and the ferrule 8 shown in Fig. 3 is removed to remove the umbrella cloth 6 from the umbrella U.

[0067] Next, as shown in Fig. 2, the ribs 5 are removed from the ribs 4. That is, the hook portions 52b of the central dowel hooking hooks 52 of the ribs 5 are disengaged from the hook shaft support portions 42b of the central dowels 42 of the ribs 4. Next, the ribs 5 are removed from the lower rung 3. Specifically, with the ribs 5 held at a substantially right angle to the center rod 1, the ribs 5 are pulled upward to disengage the hook portions 53b from the shaft support portions 32b. After the ribs 5 are removed from the ribs 4, the ribs 4 are removed from the upper turntable 2. Specifically, while the ribs 4 are held at a substantially right angle to the center rod 1, the ribs 4 are pulled downward to separate the hook portions 43b from the pivot supports 22c.

[0068] Next, the upper wheel 2 and the lower wheel 3 are removed from the center rod 1 by pushing the pin 20 with a tool or the like to remove it from the pin installation hole 25a.

[0069] 1 relative to the center rod 1, the threaded portion (not shown) can be separated, and the handle 9 and center rod 1 can be separated. This allows all parts of the umbrella U to be disassembled. The disassembled parts are made of resin, silicon, rubber, or recycled PET bottle fabric, so they can all be recycled and will not corrode even if they get wet with rainwater, etc.

[0070] Thus, the present invention is an umbrella U comprising a center rod 1, an upper rung 2 attached to the upper end of the center rod 1, a lower rung 3 slidably attached to the center rod 1, ribs 4 attached to the upper rung 2, ribs 5 connecting the lower rung 3 and the ribs 4, and an umbrella cloth 6 attached to the ribs 4, as shown in Figures 1, 2, 5, 8 or 11, wherein the upper rung 2 is formed with a rib support part 22, and the rib 4 has an upper rung hanging hook 43 which is removably attached to the rib support part 22.

[0071] The umbrella U has a structure in which the upper roller hook 43 is hung on the rib support part 22, so that no wire is required to attach the ribs 4 to the upper roller 2, and the work of attaching the ribs 4 is facilitated. In addition, the upper roller hook 43 can be attached to the rib support part 22 without tools. This allows a significant reduction in the time required for attaching the rib members when manufacturing the umbrella U and for removing the rib members when disassembling the umbrella U for disposal, etc.

[0072] As shown in Figures 1, 2, 4, 9 and 11, umbrella U comprises a center rod 1, an upper rung 2 attached to the upper end of the center rod 1, a lower rung 3 slidably attached to the center rod 1, ribs 4 attached to the upper rung 2, ribs 5 connecting the lower rung 3 and the ribs 4, and an umbrella cloth 6 attached to the ribs 4. The lower rung 3 is formed with a rib support portion 32, and the ribs 5 have a lower rung hanging hook 53 that is removably attached to the rib support portion 32.

[0073] The umbrella U has a structure in which the rib support part 32 is hooked onto the lower wheel hook 53, so that no wire is required to attach the rib 5 to the lower wheel 3, making it easy to attach the rib 5. In addition, the lower roller hook 53 can be attached to the rib support part 32 without tools. This allows a significant reduction in the time required for the attachment of the rib members when manufacturing the umbrella U and for the removal of the rib members when disassembling the umbrella U for disposal, etc.

[0074] Also, as shown in Figures 2, 3, 5 and 8, the rib support portion 22 has an engagement groove 22b into which the tip of the upper roller hanging hook 43 is inserted, and a support portion 22c into which the upper roller hanging hook 43 is removably and rotatably engaged.

[0075] According to this configuration, the ribs 4 can be easily rotated in the up-down direction, but are difficult to rotate in the left-right direction, so that the umbrella U can be opened and closed smoothly.

[0076] Also, as shown in Figures 2, 4 and 9, the rib support portion 32 has an engagement groove 32a into which the tip of the lower wheel hanging hook 53 is inserted, and a support portion 32b into which the lower wheel hanging hook 53 is removably and rotatably engaged.

[0077] According to this configuration, the ribs 5 can easily rotate up and down, but cannot easily rotate left and right, so that the umbrella U can be opened and closed smoothly.

[0078] As shown in FIG. 2 or FIG. 11, the lower turntable hanging hook 53 has a lower turntable engaging portion 53c, and the rib support portion 32 has a holding portion 32c that detachably holds the lower turntable engaging portion 53c.

[0079] When the holding portion 32c of the rib support portion 32 holds the lower turntable engagement portion 53c of the rib 5, the umbrella U can be maintained in a closed state. In addition, this configuration does not require parts such as a retractor, so the number of parts, assembly steps, and assembly time can be reduced.

[0080] As shown in FIG. 2 or FIG. 11, the rib 4 has a center dowel 42, and the rib 5 has a center dowel retaining hook 52 that is removably attached to the center dowel 42.

[0081] The middle dowel hanging hook 52 can be attached to the middle dowel 42 of the rib 4 without tools. As a result, the ribs 4 and the ribs 5 can be easily connected when manufacturing the umbrella U, and the ribs 4 and the ribs 5 can be easily separated when disassembling the umbrella U for disposal, etc., thereby improving the workability of assembly and disassembly operations.

[0082] Also, as shown in Figures 2 and 11, the rib 4 has a rod-shaped rib body 41, and the middle dowel 42 has a tubular portion 42a into which the rib body 41 is inserted, and a hook support portion 42b that supports the middle dowel hanging hook 52 rotatably and removably.

[0083] According to this configuration, the middle dowel 42 can be attached by inserting the rib body 41 into the tubular portion 42a of the middle dowel 42, and when disassembling the umbrella U for disposal, etc., the middle dowel 42 can be easily removed by pulling the rib body 41 out of the tubular portion 42a. In addition, since the central dowel 42 has a hook pivot portion 42b that pivotally and detachably supports the central dowel retaining hook 52, the rib 5 can be easily attached to and detached from the rib 4.

[0084] [First Modification] The flexible joint J according to this embodiment has been described in detail above with reference to Figures 1 to 12. However, the present invention is not limited to this, and can be modified as appropriate without departing from the spirit of the present invention. For example, the configuration of the ferrule 8 may be changed as appropriate. Figure 13 is an exploded enlarged cross-sectional view showing a first modified example of the ferrule of the umbrella according to the embodiment of the present invention.

[0085] As in the ferrule 8A shown in Fig. 13, the anti-slip part 82A may be a part that covers the ferrule body 81A. The anti-slip part 82A has a spherical outer fitting part 82Aa that fits onto the hemispherical part 81Ad formed on the upper end of the ferrule body 81A, and a cylindrical part 82Ab that is inserted into the anti-slip fitting hole 81Ac.

[0086] In this case, the anti-slip portion 82A and the seal portion 83 are made of silicon or rubber, and are integrally formed with the resin ferrule body 81 by outsert molding or the like.

[0087] If there is a hemispherical spherical outer fitting portion 82Aa that covers the ferrule body 81A, the surface area of ​​the non-slip portion 82A is increased, so that the area of ​​the portion that performs the non-slip function can be made wider.

[0088] [Second modified example] FIG. 14 is an enlarged exploded cross-sectional view showing a second modified example of the ferrule of the umbrella according to the embodiment of the present invention.

[0089] A ferrule 8B of a second modified example shown in FIG. 14 has an anti-slip and sealing portion 82B that is integrally formed from silicon or rubber.

[0090] The ferrule body 81B includes a female threaded portion 81a, a screw insertion hole 81b, a slip-proof fitting hole 81Bc, a hemispherical portion 81Bd, and a cylindrical portion 81Be. The outer periphery of the hemispherical portion 81Bd is formed in a substantially hemispherical shape. The cylindrical portion 81Be is formed in a cylindrical shape without any step from the outer periphery of the hemispherical portion 81Bd.

[0091] The anti-slip and sealing portion 82B is a silicone or rubber member formed to cover the entire ferrule body 81B, and is attached to the entire outer circumferential surface of the ferrule body 81B. The anti-slip and sealing portion 82B has an anti-slip portion 82Ba, a spherical portion 82Bb, a fitting portion 82Bc, a cylindrical portion 82Bd, and a sealing portion 82Be.

[0092] The non-slip portion 82Ba is a portion that functions as a non-slip portion. The non-slip portion 82Ba includes a spherical portion 82Bb and a fitting portion 82Bc. The spherical portion 82Bb is a portion whose outer circumferential surface is formed in a substantially hemispherical shape. The fitting portion 82Bc is a portion into which the non-slip fitting hole 81Bc of the ferrule body 81B is fitted, and is formed in a cylindrical shape protruding downward from the inner surface of the spherical portion 82Bb. The cylindrical portion 82Bd is a portion whose outer circumferential surface is formed in a columnar shape without any step from the hemispherical spherical portion 82Bb. The seal portion 82Be is a portion that is placed on the top paper 61 and performs a sealing function.

[0093] The ferrule 8B of the second modified example has an anti-slip and sealing portion 82B in which the anti-slip portion 82Ba and the sealing portion 82Be are integrally formed, and therefore the anti-slip and sealing portion 82B can be attached so as to cover the entire outer periphery of the ferrule body 81.

[0094] [Third Modification] Fig. 15 is a side view showing a third modified example of an umbrella according to an embodiment of the present invention. Fig. 16 is a view showing a third modified example of an umbrella according to an embodiment of the present invention, and is an exploded enlarged side view showing a top wheel and a bottom wheel. Fig. 17 is a view showing a third modified example of an umbrella according to an embodiment of the present invention, and is an enlarged perspective view showing a top wheel. Fig. 18 is a view showing a third modified example of an umbrella according to an embodiment of the present invention, and is an enlarged perspective view of a main part showing a bottom wheel.

[0095] As shown in Figures 15 and 16, the umbrella U1 has a length L3 from the lower surface of the rib support part 22 to the upper surface of the rib support part 32 when the engaging part 2a of the upper rung 2C is engaged with the engaged part 3a of the lower rung 3C, which may be, for example, 10.5 cm, which is 1.5 cm shorter than the length L1 (see Figure 1), and a length L4 from the center of the hooking part 52b of the rib 5 to the center of the hooking part 53b may be, for example, 26.1 cm, which is 0.9 cm shorter than the length L2 (see Figure 1) (see Figure 2). The length L3 is the sum of the length L31 from the lower surface of the rib support part 22 to the lower end of the upper tube part 23C shown in Figure 16 and the length L32 from the upper surface of the rib support part 32 to the upper end of the lower tube part 31C. By doing this, as shown in Figure 15, when the umbrella U1 is open, the rib opening angle θ4 from the outer peripheral surface of the lower tube portion 31C to the rib 5C centered on the rib support portion 32 is, for example, 85 degrees, which is larger than the rib opening angle θ3 (see Figure 1).

[0096] According to this configuration, the umbrella U1 shown in FIG. 15 is different from the umbrella U shown in FIG. 1 in that the length L3 from the underside of the rib support part 22 to the upper surface of the rib support part 32 is shorter than the length L1 (see FIG. 1), the length L4 from the center of the hanging part 52b of the rib 5C to the center of the hanging part 53b is shorter than the length L2 (see FIG. 1), and the rib opening angle θ4 from the outer peripheral surface of the lower tube part 31C centered on the rib support part 32 to the rib 5C is set to 85 degrees, thereby preventing the umbrella U1 from becoming open in a so-called ``opposite state to the normal open state of an umbrella'' when hit by a strong wind.

[0097] As shown in Figs. 16 and 17, a pin installation hole 25Ca for installing the pin 20 may be formed at the location where the male thread portion 26 is formed. In addition, the lower tube portion 31C of the lower wheel 3C shown in Figures 16 and 18 has a length L32 from the upper surface of the rib support portion 32 to the upper end of the lower tube portion 31C that is shorter than the length L12 from the upper surface of the rib support portion 32 to the upper end of the lower tube portion 31C shown in Figure 2, thereby improving its strength.

[0098] [Other variations] In the above embodiment, as an example of the center rod 1 shown in Fig. 1, a double-layer structure with the inner side made of glass fiber or carbon fiber and the outer side made of resin has been described, but the present invention is not limited to this. The center rod 1 may be made of a non-ferrous metal such as an aluminum alloy, or stainless steel.

[0099] In this way, the center pole 1 can be made of non-ferrous metals such as aluminum alloys or stainless steel, and still have corrosion resistance and strength. As described above, the components such as the center pole 1 used in the umbrella U can be easily assembled and disassembled, so even if the center pole 1 is made of non-ferrous metals or stainless steel, it can be recycled by smoothly separating the garbage.
