Description

[Technical field]

[0001] The present invention relates to a shoe drying tool that can be used in a self-supporting state and can support shoes in a floating state. [Background technology]

[0002] Conventionally, there are shoe drying tools that are used for the purpose of drying wet athletic shoes after washing, wet boots after water sports, etc. As such shoe drying tools, hanger-type ones that are hung on a clothesline or the like are widely known (see Patent Document 1). The shoe drying tool described in Patent Document 1 has a hook that is hung on a clothesline or the like and two arm-shaped members that extend upward, and by inserting these arm-shaped members into the inside of the shoe, it becomes easy for air to enter the inside of the shoe, and the shoe opening faces downward, making it easy for moisture inside to escape. Although such hanger-type ones can be hung in a sunny or well-ventilated place, they cannot be used in a place where there is no object to hang the hook.

[0003] In contrast, there are shoe drying tools that can stand on the ground or floor (see, for example, Patent Document 2). The shoe drying tool described in Patent Document 2 has a support base that is roughly cross-shaped in plan view and stands on the ground or floor, a pole that stands up from the support base, and a shoe hanger that is fixed around the pole and extends upward, and is designed so that the inside of the shoes are inserted into the shoe hanger.

[0004] [Patent Document 1] Unexamined Utility Model Publication No. 59-157670 (Page 3, Figure 1) [Patent Document 2] JP-A-4-15094 (page 2, figure 1) Summary of the Invention [Problem to be solved by the invention]

[0005] The shoe drying tool as described in Patent Document 2 can be used even in places where there is no object to hang the hooks on, since it can stand on the ground or floor. In addition, the shoe racks that support the shoes extend radially from the support poles, and the shoes are spaced apart to improve ventilation and allow for effective drying. Since such a shoe drying tool tends to get in the way of people passing by when not in use, it is preferable to store it in a place where it will not get in the way. However, since it has the shoe racks that extend radially as described above, in order to make the shoe drying tool stable and stand on its own, the support base has a sturdy structure that is roughly cross-shaped in plan view, which poses the problem of requiring a large space for storage.

[0006] The present invention has been made in consideration of such problems, and has as its object to provide a shoe drying tool that can be stored compactly when not in use. [Means for solving the problem]

[0007] In order to solve the above problems, the shoe drying tool of the present invention comprises: A shoe drying tool that can be used in a self-supporting state and can support shoes in a floating state, The shoe rack has a base and at least three rod members arranged at a distance from each other around the periphery of the base, on which shoes can be hung; The rod member is characterized in that a central portion in the up-down direction is pivotally supported on the base portion. According to this feature, by tilting the rod members in the same direction relative to the base, the lower ends of the rod members are separated from each other, and these lower ends become legs that contact the floor or ground. Then, the rod members lean on the upper parts of the rod members adjacent to them in the tilting direction, and further tilting is restricted, so that the upper ends can be sufficiently separated from each other and deployed, and shoes supported by each rod member can be effectively dried. In addition, by converging the rod members so that they are aligned in parallel, the shoe drying tool can be transformed into a slim rod shape, which can be stored compactly when not in use and is highly portable.

[0008] The base portion is characterized in that it forms a regular polygon in a plan view, and the rod members are pivotally attached in parallel to each side surface. According to this feature, the rod members can be evenly distributed around the base, and by opposing the base and the rod members in parallel, a sufficient contact area is ensured, thereby dispersing the stress applied to the pivot points between the rod members and the base, thereby preventing damage.

[0009] The base portion is elongated, and its upper end portion in the longitudinal direction extends to at least the upper end portion of the rod member. This feature makes it easy to grasp the upper end of the base and to deploy or converge the rod member.

[0010] The base portion is characterized by having a hook portion provided at an upper end portion in the longitudinal direction. According to this feature, in addition to being able to stand it on the floor, shoes can be hung and dried by hanging it from a clothesline or the like using the hook part.

[0011] The rod members consist of four rods, and one of the two sets of rod members facing each other across the base has a width dimension smaller than the width dimension of the base, while the other set of rod members has a wide portion having a width dimension larger than the width dimension of the base. According to this feature, in the collapsed state, the rod members of one set are sandwiched between the rod members of the other set extending from both sides of the base, thereby preventing them from accidentally rotating in the deployment direction.

[0012] The rod member of the other set has a rod-shaped portion and a tip portion connected to the upper end of the rod-shaped portion so as to be rotatable in the horizontal direction, and the tip portion has a bifurcated structure. According to this feature, the tip of the forked structure can grip the ankle portion of the shoe body, and the opening is supported facing diagonally downward outward, which makes it easier for air to enter the inside of the shoe and allows moisture to be efficiently expelled from the opening, allowing the shoe to dry efficiently.

[0014] The shoe drying tool according to the present invention will be described below with reference to the following examples. EXAMPLES

[0015] A shoe drying tool according to a first embodiment will be described with reference to Figs.

[0016] Shoe drying devices are used for the purpose of drying wet sneakers after washing, wet surf boots after water sports, etc., and the shoe drying device of this embodiment has a structure that is particularly useful for drying surf boots.

[0017] As shown in FIG. 1, the shoe drying tool 1 is mainly composed of a base 2 and four rod members 3A to 3D that are arranged around the periphery of the base 2 and spaced apart from each other in the circumferential direction.

[0018] The base 2 has a long rod-shaped portion 4 and a hook 5 provided at one end (upper end) in the longitudinal direction of the rod-shaped portion 4. As shown in Fig. 2, the rod-shaped portion 4 is made of synthetic resin and has a substantially rectangular shape in a plan view having four side surfaces 41A to 41D. The corners where adjacent side surfaces intersect are rounded and chamfered. The hook 5 is pivotally attached to a recess (not shown) formed in the upper end 4a of the rod-shaped portion 4, and is connected to the rod-shaped portion 4 so as to be rotatable in the horizontal direction and undetachable in the axial direction.

[0019] The rod-shaped portion 4 has a connection portion 40 at the other end (lower end) in the longitudinal direction to which the rod members 3A to 3D described above are connected. Recesses 42, which will be described in detail later, are formed on each of the side surfaces 41A to 41D of the rod-shaped portion 4 that constitute the connection portion 40. In addition, protrusions 43 are provided on either side of the recesses 42 in the longitudinal direction (up-down direction) of the rod-shaped portion 4. The recesses 42 are located at the center of the side surfaces of the rod-shaped portion 4 in the width direction.

[0020] 2(a), the upper and lower protrusions 43, 43 have the same shape and form a hexagon in side view. The upper and lower protrusions 43, 43 are disposed at the same distance from the recess 42 in the longitudinal direction of the rod-shaped portion 4, and the protrusion 43, recess 42, and protrusion 43 are linearly arranged along the longitudinal direction of the rod-shaped portion 4. The upper and lower protrusions 43, 43 are also disposed in the same phase so that the sides (side surfaces 43a) of the hexagon are parallel to each other.

[0021] As shown in Figure 3, rod members 3A to 3D, rod member 3A and rod member 3C, and rod member 3B and rod member 3D, have the same shape, and rod member 3A and rod member 3C are arranged opposite each other with base 2 in between, and similarly rod member 3B and rod member 3D are arranged opposite each other with base 2 in between.

[0022] Next, rod member 3B will be described with reference to Fig. 4. Rod member 3D has the same shape as rod member 3B, so a description thereof will be omitted here. Rod member 3B is made of synthetic resin and is formed in a long, generally rectangular shape, with outwardly protruding rounds at upper end 31a and lower end 31b.

[0023] The rod member 3B has peripheral walls 32 along the outer edges on the front and back sides in the thickness direction, and has a ribbed structure with a flat plate portion 33 in the center in the thickness direction. A rotating shaft 34 is formed on the back surface 33a of the flat plate portion 33, which is pivotally attached to a recess 42 formed in the connection portion 40 of the rod-shaped portion 4. As a result, the rod member 3B is connected to the connection portion 40 of the rod-shaped portion 4 so as to be swingable and undetachable. The rotating shaft 34 is disposed in the center in the width direction of the rod member 3B. The rod member 3B is attached so that the flat plate portion 33 faces the side surface 41B of the rod-shaped portion 4, and the peripheral wall 32 and the side surface 41B are close to each other.

[0024] Next, rod member 3A will be described with reference to Fig. 5. Rod member 3C has the same shape as rod member 3A, so its description will be omitted here. Rod member 3A is composed of a rod-shaped portion 35 and a tip portion 36 pivotally attached to one end (upper end) of rod member 35 so as to be rotatable in the horizontal direction.

[0025] The rod-shaped portion 35 has peripheral walls 32 along the outer edges on both the front and back sides in the thickness direction, and a ribbed structure with a flat plate portion 33 in the center in the thickness direction. The rod-shaped portion 35 is made of synthetic resin and is formed in a long, roughly rectangular shape, with an outwardly protruding round at the lower end portion 31b. The rod-shaped portion 35 of the rod member 3A is attached so that the flat plate portion 33 faces the side surface 41A of the rod-shaped portion 4 of the base 2, and so that the peripheral wall 32 and the side surface 41A are close to each other.

[0026] A rotating shaft 34 is formed on the back surface 33a of the flat plate portion 33 of the rod-shaped portion 35, and is pivotally attached to a recess 42 formed in the connecting portion 40 of the rod-shaped portion 4. As a result, the rod member 3A is connected to the connecting portion 40 of the rod-shaped portion 4 so as to be swingable and undetachable. The rotating shaft 34 is disposed in the center of the rod member 3A in the width direction.

[0027] In addition, the peripheral wall 32 constituting the upper end of the rod-shaped portion 35 is formed to have a greater wall thickness than the other portions, and a recess 37 is formed in this peripheral wall which opens at the upper end in the axial direction, and a rotating shaft 38 formed at the lower end of the tip portion 36 is pivotally attached to this recess 37.

[0028] The tip portion 36 has a bifurcated structure that is open from the tip to the center in the longitudinal direction, and the entire portion, including the two extension portions 39 that make up the bifurcated structure, has peripheral walls 32' along the outer edges on the front and back sides in the thickness direction, and a ribbed structure with a flat portion 33' in the center in the thickness direction.

[0029] The width dimension L1 of the end of the tip portion 36 on the rod-shaped portion 35 side is approximately the same as that on the rod-shaped portion 35 side, and the width dimension gradually increases from there toward the center in the longitudinal direction, reaching a maximum near the base of the bifurcated extension portion 39. The width dimension L2 of the wide portion 36c having this maximum width dimension is naturally larger than the width dimension L1 and is also larger than the width dimension L3 of the base portion 2 (see FIG. 2(b)).

[0030] As shown in Figure 3, rod member 3A is arranged on side 41A of base 2, rod member 3B is arranged on side 41B, rod member 3C is arranged on side 41C, and rod member 3C is arranged on side 41C so that the back surfaces of flat plate portion 33 (33') face each other, and each is pivotally mounted so as to be rotatable.

[0031] 3, width dimension L4 of rod member 3B is slightly smaller than width dimension L5 of side surface 41B of base 2. Width dimension L1 of the end of tip 36 of rod member 3A on the rod-shaped portion 35 side and width dimension L1' of rod portion 35 (see FIG. 5) are approximately the same as width dimension L4 of rod member 3B and slightly smaller than width dimension L6 of side surface 41A of base 2. Width dimension L4 of rod member 3B may be the same as width dimension L5 of side surface 41B of base 2, and width dimension L1' of rod portion 35 of rod member 3A may be the same as width dimension L6 of side surface 41A of base 2.

[0032] Width dimension L2 of wide portion 36c, which is the maximum width of tip portion 36 of rod member 3A, is larger than width dimension L6 on the side surface 41A side of base portion 2, and when rod members 3A to 3D converge (see FIG. 3), rod members 3B and 3D are sandwiched between tip portion 36 of rod member 3A and tip portion 36 of rod member 3C. In addition, the dimension from the bottom end of rod member 3B to the center of rotation shaft 34 is the same as the dimension from the bottom end of rod member 3A to the center of rotation shaft 34.

[0033] Next, an example of a method of using the shoe drying tool 1 will be described with reference to Fig. 1 and Figs. 6 to 10. When not in use, the shoe drying tool 1 can be folded into a rod shape with all of the rod members 3A to 3D parallel to the base 2 as shown in Fig. 6.

[0034] The dimension L7 from the upper end of rod member 3B to the center of the rotating shaft 34 (see Figure 4(b)) and the dimension L8 from the upper end of rod member 3A to the center of the rotating shaft 34 (see Figure 5(b)) are the same as the dimension L9 from the center of the recess 42 in the base 2 to the upper end 4a of the rod-shaped portion 4 (see Figure 2(a)).In the converged state shown in Figure 6, the upper end 4a of the rod-shaped portion 4 is aligned with the upper ends 31a of the rod members 3A to 3D, which not only improves the aesthetic appearance but also prevents the tips of the rod members 3A and 3C from protruding, thereby preventing them from being caught and damaged when carried.

[0035] In this way, in the collapsed state, the rod members 3A-3D and the base 2 are aligned in parallel, and the shoe drying tool 1 is transformed into a slim rod shape, allowing it to be stored compactly when not in use. It is also slender and easy to grip, making it highly portable. In addition, the shoe drying tool 1 can be made to stand stably on its own by appropriately inserting the lower parts of the rod members 3A-3D into uneven ground such as a sandy beach, since the lower parts of the rod members 3A-3D below the rotation axis 34 form legs that come into contact with the ground.

[0036] In addition, in the converged state, rod members 3B and 3D are sandwiched between the tip 36 of rod member 3A and the tip 36 of rod member 3C, so that the rotation of rod members 3B and 3D about rotation axis 34 is restricted by rod members 3A and 3C, effectively preventing them from suddenly deforming into the unfolded state.

[0037] FIG. 1 is a diagram showing the shoe drying tool 1 in an unfolded state and standing on a floor surface F. First, the procedure for unfolding the shoe drying tool 1 will be described. The rod members 3A to 3D are rotated about the rotation shaft 34 in the same direction when viewed from the side. Here, they are rotated counterclockwise, but they may be rotated clockwise. Then, the tip portions 36 of the rod members 3A and 3C are rotated 90 degrees horizontally relative to the rod-shaped portion 35.

[0038] Figure 7 is a top view of the shoe drying device 1 in an unfolded state. As shown in Figures 1 and 7, the part above the rotation axis 34 of rod member 3A is leaning below the rotation axis 34 of rod member 3B, the part above the rotation axis 34 of rod member 3B is leaning below the rotation axis 34 of rod member 3C, the part above the rotation axis 34 of rod member 3C is leaning below the rotation axis 34 of rod member 3D, and the part above the rotation axis 34 of rod member 3D is leaning below the rotation axis 34 of rod member 3A.

[0039] Fig. 8 is a diagram showing a state in which rod member 3C is rotated counterclockwise around rotation shaft 34, and for convenience of explanation, rod member 3A is not shown. As shown in Fig. 8, protrusions 43, 43 formed on connection portion 40 of base 2 are arranged in a hollowed-out space surrounded by peripheral walls 32, 32 facing each other in the width direction of rod member 3B and flat plate portion 33, or in a hollowed-out space surrounded by peripheral walls 32, 32 facing each other in the width direction of rod-shaped portion 35 of rod member 3C and flat plate portion 33.

[0040] When the rod member 3B is rotated counterclockwise around the rotation axis 34 of the protrusion 43, the peripheral walls 32, 32 facing in the width direction of the rod member 3B or the peripheral walls 32, 32 facing in the width direction of the rod member 3C come into contact with the side surfaces 43a of the upper and lower protrusions 43, respectively, thereby defining the rotation range of the rod member 3B or the rod member 3C. In this embodiment, the protrusion 43 is a regular hexagon, so that the outer angles are each 60 degrees, and the rod members 3B and 3C that come into contact with the side surfaces 43a can be inclined at a maximum of 30 degrees with respect to the base 2. The rod members 3B and 3C come into contact with the protrusion 43 when rotated counterclockwise or clockwise.

[0041] In this manner, the rod members 3A to 3D are each resting against the upper side of the rod member adjacent thereto in the inclined direction, so that the rotation range is restricted, and also the rotation range is restricted by contact with the protrusion 43.

[0042] 1, the shoe drying tool 1 in the unfolded state can be made to stand on the floor surface F by abutting the lower end portions 31b of the rod members 3A to 3D against the floor surface F. In this state, since the lower end portions 31b of the rod members 3A to 3D are in contact with the floor surface F, the clockwise rotation of these rod members 3A to 3D is restricted, and since the rod members 3A to 3D are leaning against the lower portion of the rotation shaft 34 of the adjacent rod members, the counterclockwise rotation is restricted.

[0043] 9, the shoe S is held and supported between the two extensions 39, 39 constituting the bifurcated structure of the tip end 36 of the rod members 3A, 3C. More specifically, it is preferable that the shoe body SB is held between the extensions 39, 39 with the sole SL of the shoe S facing the base 2 and the opening H facing diagonally downward outward.

[0044] In this embodiment, the shoes S are so-called surf boots, with the shoe body SB including the ankle part AK being made of a flexible material such as neoprene that is easily deformed, and the sole part SL being made of a material such as rubber that is less likely to deform than the shoe body SB. Also, compared to sneakers and the like, the shoe body SB has a certain length up to the opening H.

[0045] The tip portion 36 has a curved recess 36a at the base of the inner side of the extensions 39, 39, and the inner surface is generally U-shaped, and the shoe S with the shoe body SB gripped is pushed to the base of the extensions 39, 39 by its own weight while being guided between the extensions 39, 39, and the ankle portion AK is pressed against the curved recess 36a. As a result, the ankle portion AK is deformed to conform to the inner shape of the curved recess 36a, and the tubular portion T having the opening H at the tip expands so as to extend vertically (see FIG. 10(b)). Note that FIG. 10 is an image diagram showing a cross section of the portion of the tubular portion T sandwiched between the extensions 39, 39.

[0046] This allows air to easily get into the shoe S, and also allows moisture inside the shoe S to be easily guided through the ankle part AK, whose shape is stable when spread out along the curved recess 36a, to the opening H, allowing the moisture to be efficiently discharged and the shoe to be efficiently dried.

[0047] Furthermore, the distance between the extensions 39, 39 is smaller than that of the sole SL, and the extensions 39, 39 are aligned along the longitudinal direction of the sole SL, so that the contact area is large and the shoe S can be reliably supported when dropped.

[0048] In addition, the rod members 3A, 3C grip the area near the ankle portion AK, and the sole portion SL, which is made of a material that is not easily plastically deformed, is positioned above the extension portions 39, 39 to prevent it from slipping out from between these extension portions 39, 39.As a result, there is no risk of the rod members 3A, 3C coming into localized contact with a part of the shoe body portion SB, which is particularly flexible, causing the shoe S to lose its shape.

[0049] In addition, the tip portion 36 has a wide portion 36c having the widest dimension at the base of the extensions 39, 39 which receive the weight of the shoe S, thereby achieving miniaturization and weight reduction while ensuring structural strength in the minimum necessary areas.

[0050] In addition, the dimension from the upper end 31a of the rod members 3A, 3C to the bottom end of the curved recess 36a is approximately twice the distance from the bottom end of the curved recess 36a to the rotation axis 34, and since it is immediately apparent that the dimension from the upper end 31a to the bottom end of the curved recess 36a is relatively large, the user can be guided to position the ankle portion AK side, which is closer to the opening H, on the side of the curved recess 36a, rather than the toe side, which is farther from the opening H.

[0051] Furthermore, when the sole portion SL is placed downward, the shoe body portion SB held by the extension portions 39, 39 is highly flexible and deforms, causing the shoe S to fall off without getting caught between the extension portions 39, 39, so that the user can be guided to place the sole portion SL on top.

[0052] Furthermore, as shown in FIG. 7, the tip portion 36, which is rotated horizontally relative to the rod-shaped portion 35, is formed so that the curved recess 36a partially overlaps with the base portion 2 left and right (front and back) when viewed in a plane, so that the shoes S held by the extension portions 39, 39 are close to the base portion 2, which is the center of gravity of the shoe drying device 1, and even shoes S that have become wet and heavy can be stably supported.

[0053] In addition, since the rod members 3A, 3C with the shoes S hung on their upper ends 31a lean lower than the rotating shafts 34 of the adjacent rod members 3B, 3D, the counterclockwise rotation of the rotating shafts 34 of these rod members 3B, 3D is suppressed, and the unfolded state of the shoe drying device 1 is more firmly maintained.

[0054] Although not shown here, gloves can be hung on the upper ends 31a of the rod members 3B and 3D.

[0055] Furthermore, the shoe drying tool 1 can be suspended from a clothesline or the like using the hook 5 in either the collapsed state or the unfolded state. When suspended in the unfolded state, the rod members 3A to 3D are adapted to have their rotation range restricted by contact with the protrusions 43.

[0056] Furthermore, since the width dimension L2 of the widest portion 36c of the tip 36 of the rod members 3A and 3C is larger than the width dimension L1' of the rod-shaped portion 35, when the tip 36 is in the unfolded state facing the vertical direction, the wide portion 36c of the tip 36 interferes with the base 2, thereby restricting rotation in the convergence direction.

[0057] In addition, the base 2 forms a regular polygon when viewed in a plane, and the rod members 3A to 3D are pivotally attached parallel to each of the side surfaces 41A to 41D. By thus arranging the base 2 and the rod members 3A to 3D facing each other in parallel, a sufficient contact area is secured and the stress applied to the pivot points between the rod members 3A to 3D and the base 2 can be distributed, effectively preventing breakage.

[0058] Furthermore, since the base 2 is long and the upper end 4a in the longitudinal direction extends to the upper ends 31a of the rod members 3A to 3D, it is easy to grasp the upper portion of the base 2 and to unfold or converge the rod members 3A to 3D. EXAMPLES

[0059] Next, a shoe drying tool according to a second embodiment will be described with reference to Figures 11 and 12. Note that the same components as those in the first embodiment will be given the same reference numerals and duplicated descriptions will be omitted.

[0060] As shown in Fig. 11, the rotating shaft 34' of the rod members 3A' to 3D' (only the rotating shaft 34' of the rod member 3A is shown here) is pivotally attached to the receiving portion 142 of the base 2' in the second embodiment. The receiving portion 142 has a cylindrical portion 142a that protrudes outward and a recess 142b formed in the cylindrical portion 142a. The rotating shaft main body 34b of the rotating shaft 34' of the rod member 3A is inserted into the recess 142b, and the cylindrical portion 142a is loosely fitted into the annular groove 34b that surrounds the base portion of the rotating shaft 34' of the rod member 3A'.

[0061] Figure 12 shows how rod member 3C' is rotated counterclockwise around rotating shaft 34 (Figure 12(a) is at 0 degree position relative to base 2', (c) is at 30 degrees), and for ease of explanation, rod members 3A', 3B', and 3D' are not shown. As shown in Figure 12, protrusions 43A, 43B formed on base 2' are located within a hollowed-out space surrounded by peripheral walls 32, 32 facing each other in the width direction of rod member 3C' and arc-shaped peripheral walls 32A, 32B formed above and below along the outside of groove 34b surrounding the base of rotating shaft 34'.

[0062] In the hollowed-out space, the arc-shaped peripheral wall 32A and the peripheral wall 32 intersect with each other through an arc-shaped surface, and one of the left and right peripheral walls 32 has a protrusion 145A that bulges into the hollowed-out space. The arc-shaped peripheral wall 32A and the protrusion 145A are continuously formed as an arc with the same curvature radius, which is equal to the curvature radius of the circular protrusion 43A, and the intersection of the arc-shaped peripheral wall 32A and the protrusion 145A constitutes an engagement portion 144A where the protrusion 43A is engaged. In addition, an engagement portion 144B and a protrusion 145B are formed with a similar configuration.

[0063] As shown in the balloon in FIG. 12(a), the final point F on the inner side of the end of the protrusion 145A is formed at a position extending in the circumferential direction from a point E where a virtual line x along a radial direction connecting a boundary point D where the curvature radius and curvature direction of the locking portion 144A and the curvature direction of the peripheral wall 32A change and the curvature center O of the locking portion 144A intersects with the inner surface of the end of the protrusion 145A. In other words, in a convergent state in which the rod member 3C' is parallel to the base 2', the projection 43A located inside the locking portion 144A is restricted from moving in the counterclockwise direction by the protrusion 145A. In addition, the clockwise movement is also restricted by the locking portion 145A.

[0064] When the rod member 3C' is rotated counterclockwise relative to the base portion 2' from the state shown in FIG. 12(a), 12(b), convex portion 43A climbs over projection 145A and is disengaged from locking portion 144A. Since convex portion 43A and projection 145A are formed of synthetic resin integrally with rod member 3C' and base portion 2', respectively, they have some elasticity, and when rod member 3C' is rotated, convex portion 43A and projection 145A each elastically deform, allowing convex portion 43A to climb over projection 145A.

[0065] Next, when the rod member 3C' is further rotated counterclockwise relative to the base portion 2' from the state shown in Fig. 12(b), the convex portion 43B passes over the projection 145B and is locked by the locking portion 145B as shown in Fig. 12(c). In addition, the movement in the counterclockwise direction is also restricted by the locking portion 145B.

[0066] In this manner, by engaging the protrusions 43A with the locking portions 144A and the protrusions 43B with the locking portions 144B, the relative rotation of the rod members 3A' to 3D' with the base 2' in the collapsed and unfolded states is simply restricted, thereby enabling the collapsed and unfolded states to be maintained.

[0067] Although the embodiments and modified examples of the present invention have been described above with reference to the drawings, the specific configuration is not limited to these embodiments, and the present invention also includes modifications and additions that do not deviate from the gist of the present invention.

[0068] For example, the rotation restriction means for maintaining the deployed state of the rod members 3A to 3D is not limited to the configuration using the convex portion 43 as described above, but may use a high-friction material at the pivot point between the concave portion 42 and the rotating shaft 34, or may provide a temporary locking means that is elastically deformable.

[0069] Moreover, all four of the rod members 3A to 3D may have the same structure, or conversely, they may each have a different structure.

[0070] Furthermore, when the shoe drying tool 1 is used only in a free-standing state, the means for restricting the rotation of the rod members 3A to 3D by the protrusions 43 may be omitted.

[0071] Furthermore, the cross section of the base 2 is not limited to a square, but may be a circle.

[0072] Furthermore, the base 2 is not limited to a square as long as it forms a regular polygon in a plan view, but may be, for example, an equilateral triangle, in which case there will be three rod members.

[0073] Furthermore, since the tip portion 36 can rotate, it does not get in the way when in the converged state, but the tip portion 36 may be integral with the rod-shaped body so that its surface faces in the up and down directions when in the unfolded state.

[0074] Furthermore, the upper end 4a of the base 2 may protrude upward beyond the upper ends 31a of the rod members 3A to 3D. [Explanation of symbols]
