[0013] Hereinafter, an example of an embodiment of an assembly chair according to the present disclosure will be described in detail with reference to FIGS.

[0014] Fig. 1 is a perspective view showing the draining device 1 in use. Fig. 2 is a plan view showing the draining device 1 shown in Fig. 1. Fig. 3 is a front view showing the draining device 1 shown in Fig. 1, in which of a pair of fittings 2 described later, an outer pipe fitting 212 is shown at the front and an inner pipe fitting 211 is shown at the back. The draining device 1 according to the present invention can be in a use state in which tableware and the like can be placed as shown in Figs. 1 to 3, and in a storage state suitable for storage as shown in Figs. 10 and 11, which will be described later.

[0015] The draining device 1 according to the present disclosure includes a pair of mounting fixtures 2 and a plurality of tubular members 3 fixed to the pair of mounting fixtures 2 and extending between the pair of mounting fixtures 2. In the present disclosure, the mounting fixtures 2 are made of a flexible material and are bendable. The tubular members 3 include an outer tube 31 and an inner tube 32 nested within the outer tube 31. The inner tube 32 is slid relative to the outer tube 31 to change the length of the tubular members 3, thereby bending the mounting fixtures 2, allowing the device to be freely switched between a use state and a storage state.

[0016] Next, each component of the water drainer 1 will be further described.

[0017] First, the mounting fixture 2 will be described. As described above, the draining device 1 is provided with a pair of mounting fixtures 2 that extend in an elongated shape. In the example shown in Figs. 1 to 3, the mounting fixtures 2 extend in a first extension direction d1 when the draining device 1 is in use. One of the pair of mounting fixtures 2 is an inner pipe mounting fixture 211 to which the inner pipe 32 of the tubular member 3 is attached. The other of the pair of mounting fixtures 2 is an outer pipe mounting fixture 212 to which the outer pipe 31 of the tubular member 3 is attached.

[0018] The mounting fixture 2 has a plurality of mounting parts 21 to which the tips of the tubular members 3 are attached. In the example shown in Figs. 1 to 3, the plurality of mounting parts 21 each have a recess 21a into which the tips of the tubular members 3 are inserted. When the draining device 1 is deployed in a usage state as shown in Figs. 1 to 3, the plurality of mounting parts 21 are aligned in the first extension direction d1. The mounting fixture 2 also has a connection part 22 that connects the plurality of mounting parts 21 together. When the draining device 1 is deployed in a usage state as shown in Figs. 1 to 3, the mounting parts 21 and the connection parts 22 are aligned alternately in the first extension direction d1, and the mounting parts 21 are aligned at equal intervals in the first extension direction d1. In the example shown in Figs. 1 to 3, each of the pair of mounting fixtures 2 has nine mounting parts 21 and eight connection parts 22.

[0019] The constituent material of each mounting fixture 2 will be described. Each mounting fixture 2 is made of a flexible material and is bendable. In other words, each mounting fixture 2 is made of a flexible material that is flexible enough to be bendable. The mounting fixture 2 shown in Figs. 1 to 3 has a smaller thickness at the connection portion 22 than at the mounting portion 21. For this reason, the mounting fixture 2 is bendable at the connection portion 22. As an example, the connection portion 22 has a flexibility to such an extent that the two mounting portions 21 located on both sides of the connection portion 22 can be brought into contact with each other by bending the connection portion 22. The flexible material used as the material of the mounting fixture 2 is, for example, a flexible material such as silicone rubber.

[0020] Moreover, a hanging part 23 for suspending the draining device 1 is attached to at least one of the pair of mounting fixtures 2. In the example shown in Figs. 1 to 3, the hanging part 23 is attached to the inner pipe mounting fixture 211, and the hanging part 23 is not attached to the outer pipe mounting fixture 212. Although not shown, the hanging part 23 may be attached to the outer pipe mounting fixture 212, and the hanging part 23 may not be attached to the inner pipe mounting fixture 211. Moreover, the hanging part 23 may be attached to both the outer pipe mounting fixture 212 and the inner pipe mounting fixture 211.

[0021] The hanging part 23 is a part that can be hung on a hook or the like provided on the wall of a house, for example, to hang the draining device 1 on the wall of the house. The shape of the hanging part 23 is not particularly limited as long as it can be hung on a hook or the like. In the example shown in Figs. 1 to 3, the hanging part 23 is an arc-shaped part connected to the mounting part 21 at both ends. As an example, the hanging part 23 is integrally formed with the mounting part 21 and the connection part 22 of the mounting tool 2.

[0022] Next, the tubular member 3 will be described. As described above, the water draining device 1 includes a pair of mounting fixtures 2 and a plurality of tubular members 3 fixed to the pair of mounting fixtures 2 and extending between the pair of mounting fixtures 2. The tubular members 3 are fixed to the mounting fixtures 2 by attaching the tips of the tubular members 3 to mounting portions 21 of the mounting fixtures 2. As shown in Figs. 1 and 2, the plurality of tubular members 3 are arranged parallel to one another, and each tubular member 3 extends along the second extension direction d2.

[0023] When the draining device 1 is deployed in a usable state, a first extension direction d1 in which the mounting fixture 2 extends and a second extension direction d2 in which the tubular member 3 extends are perpendicular to each other. When the draining device 1 is deployed in a usable state as shown in Figs. 1 and 2, the multiple tubular members 3 are arranged at equal intervals. In this case, the draining device 1 includes nine tubular members 3. With the draining device 1 in a usable state, water can be drained from wet items by placing them on the multiple tubular members 3.

[0024] As described above, each tubular member 3 includes an outer tube 31 and an inner tube 32 nested within the outer tube 31. The inner tube 32 is slidable relative to the outer tube 31 while maintaining a state in which at least a portion of the inner tube 32 is housed within the outer tube 31. By sliding the inner tube 32 relative to the outer tube 31, the length of the tubular member 3 can be changed, and by changing the length of the tubular member 3, the inner tube 32 can be pulled out from the outer tube 31, thereby changing the dimension of the water draining device 1 in the second extension direction d2.

[0025] 2, the outer tube 31 of the tubular member 3 has an axis L1 extending through the center of the outer tube 31. Moreover, the inner tube 32 of the tubular member 3 has an axis L2 extending through the center of the inner tube 32, and the axis L1 and the axis L2 extend collinearly along the second extension direction d2.

[0026] In the draining device 1 according to this embodiment, at least one of the multiple tubular members 3 is provided with a slip-out prevention portion that prevents the inner tube 32 from slipping out of the outer tube 31. As an example, the slip-out prevention portion has a protrusion provided on the outer surface of the inner tube 32 and a protrusion provided on the inner surface of the outer tube 31. In this case, when the inner tube 32 is pulled out of the outer tube 31 by more than a certain length, the protrusion provided on the outer surface of the inner tube 32 is engaged with the protrusion provided on the inner surface of the outer tube 31. This prevents the inner tube 32 from slipping out of the outer tube 31.

[0027] In this way, when at least one of the multiple tubular members 3 is provided with a slip-out prevention portion, the inner tube 32 may be pulled out from the outer tube 31 to the limit at which the inner tube 32 cannot be pulled out from the outer tube 31 due to the slip-out prevention portion. Also, the inner tube 32 may be used without being pulled out from the outer tube 31 to the limit. By adjusting the length by which the inner tube 32 is pulled out from the outer tube 31, the dimension of the draining device 1 in the second extension direction d2 in the used state can be adjusted. This allows, for example, when placing the draining device 1 on a sink, the dimension of the draining device 1 in the second extension direction d2 to be adjusted to match the size of the sink.

[0028] The tubular member 3 has a strength sufficient to withstand the weight of a wet object when the wet object is placed on the tubular member 3. The material of the tubular member 3 is, for example, stainless steel. The inner tube 32 and the outer tube 31 are, for example, stainless steel round bars.

[0029] In this embodiment, the water draining device 1 further includes a locking member 4. The locking member 4 has an inner pipe fixing part 41 fixed to the inner pipe 32 of one tubular member, and a locking part 43 connected via a connecting part 42 extending from the inner pipe fixing part 41 in the lateral direction of the tubular member 3 to lock another tubular member. In the example shown in Figs. 1 to 3, the first tubular member 3a located at the outermost position in the first extension direction d1 among the multiple tubular members 3 is the one tubular member to which the inner pipe fixing part 41 is fixed. In the example shown in Figs. 1 and 2, the second tubular member 3b adjacent to the first tubular member 3a among the multiple tubular members 3 is the other tubular member to be locked by the locking part 43.

[0030] Fig. 4 is a perspective view showing the locking member 4. Fig. 4 shows the first extension direction d1 and the second extension direction d2 when the locking member 4 is incorporated into the draining device 1 in use. In Fig. 4, the inner pipe fixing part 41 has a cylindrical shape. The inner pipe 32 of the first tubular member 3a passes through the inner pipe fixing part 41 having a cylindrical shape, and the inner pipe fixing part 41 is fixed to the inner pipe 32 of the first tubular member 3a. In this embodiment, the locking member 4 is rotatably fixed to the first tubular member 3a by the inner pipe fixing part 41.

[0031] 1 to 4 is fixed to be slidable relative to the inner pipe 32 along the second extension direction d2. Although not shown, the inner pipe fixing part 41 may have a structure that prevents it from sliding relative to the inner pipe 32.

[0032] Furthermore, the locking member 4 has a connecting portion 42 extending from the inner pipe fixing portion 41 in the lateral direction of the tubular member 3. In the example shown in Fig. 4, the connecting portion 42 extends in a direction perpendicular to the second extension direction d2.

[0033] The locking portion 43 locks the second tubular member 3b adjacent to the first tubular member 3a to which the inner pipe fixing portion 41 is fixed. By the locking portion 43 locking the second tubular member 3b, the positional relationship between the first tubular member 3a to which the inner pipe fixing portion 41 is fixed and the second tubular member 3b is determined.

[0034] The locking portion 43 has a shape that can hold the tubular member 3. In the example shown in Fig. 4, the locking portion 43 has a cylindrical shape with a part of it missing. The second tubular member 3b is inserted into the locking portion 43, which has a cylindrical shape with a part of it missing, and the locking portion 43 can lock the second tubular member 3b by holding the second tubular member 3b.

[0035] The locking portion 43 has a first locking portion 431 capable of locking the outer tube 31 of the second tubular member 3b, and a second locking portion 432 capable of locking the inner tube 32 of the second tubular member 3b. In the example shown in FIG. 4, the first locking portion 431 has a cylindrical shape with an inner diameter w1 and a part of the cylindrical shape with an inner diameter w2 and a part of the cylindrical shape with an inner diameter w2. The second locking portion 432 is located closer to the inner pipe attachment 211 than the first locking portion 431. The connecting portion 42 connects the inner pipe fixing portion 41 and the second locking portion 432 of the locking portion 43.

[0036] The inner diameter w1 of the first locking portion 431 is determined so that the first locking portion 431 can clamp the outer tube 31 of the second tubular member 3b. The inner diameter w2 of the second locking portion 432 is determined so that the second locking portion 432 can clamp the inner tube 32 of the second tubular member 3b. In the example shown in FIG. 4, the inner diameter w1 of the first locking portion 431 is larger than the inner diameter w2 of the second locking portion 432. This allows the first locking portion 431 to clamp the outer tube 31 of the second tubular member 3b, and the second locking portion 432 to clamp the inner tube 32 of the second tubular member 3b, which is thinner than the outer tube 31 of the second tubular member 3b.

[0037] Fig. 4 shows an axis L1 of the outer tube 31 of the second tubular member 3b locked to the first locking portion 431. Also, Fig. 4 shows an axis L2 of the inner tube 32 of the second tubular member 3b locked to the second locking portion 432.

[0038] Here, the first locking portion 431 and the second locking portion 432 extend coaxially. The first locking portion 431 and the second locking portion 432 "extending coaxially" means that, as shown in Fig. 4, the axis L1 of the outer tube 31 locked by the first locking portion 431 and the axis L2 of the inner tube 32 locked by the second locking portion 432 extend on the same straight line. This allows the first locking portion 431 to lock the outer tube 31 and the second locking portion 432 to lock the inner tube 32 at the same time when the locking portion 43 locks the tubular member 3 in which the axis L1 of the outer tube 31 and the axis L2 of the inner tube 32 coincide with each other.

[0039] FIG. 5 is an enlarged view of the portion where the locking portion 43 locks the second tubular member 3b in the draining device 1 deployed in the use state shown in FIGS. 1 to 3. In FIG. 5, only the mounting portion 21 to which the first tubular member 3a is fixed, the mounting portion 21 to which the second tubular member 3b is fixed, and the connection portion 22 connecting these mounting devices 2 are shown for the inner pipe mounting fixture 211, and the other portions are omitted. In the example shown in FIG. 5, the locking portion 43 contacts the inner pipe mounting fixture 211. Also, the second locking portion 432 of the locking portion 43 locks the inner pipe 32 of the second tubular member 3b. On the other hand, the first locking portion 431 of the locking portion 43 does not contact the second tubular member 3b and does not lock the second tubular member 3b.

[0040] The draining device 1 according to the present embodiment further includes an auxiliary locking member 5. The auxiliary locking member 5 includes an outer tube fixing portion 51 fixed to the outer tube 31 of the first tubular member 3a, and an auxiliary locking portion 53 connected to the outer tube fixing portion 51 via a connecting portion 52 extending laterally of the tubular member 3 to lock the second tubular member 3b. In the example shown in FIGS. 1 to 3, the outer tube fixing portion 51 of the auxiliary locking member 5 is fixed to the outer tube 31 of the first tubular member 3a having the inner tube 32 to which the inner tube fixing portion 41 of the locking member 4 is fixed. Although not shown, the outer tube fixing portion 51 of the auxiliary locking member 5 may be fixed to the outer tube 31 of a tubular member 3 other than the first tubular member 3a having the inner tube 32 to which the inner tube fixing portion 41 of the locking member 4 is fixed. In the example shown in Figs. 1 and 2, the auxiliary locking portion 53 locks the second tubular member 3b, which is located adjacent to the first tubular member 3a in the first extension direction d1, among the multiple tubular members 3.

[0041] Fig. 6 is a perspective view showing the auxiliary locking member 5. In Fig. 6, the directions marked with the symbols d1 and d2 refer to the first extension direction d1 and the second extension direction d2 when the auxiliary locking member 5 is incorporated into the draining device 1 in use. The shape of the outer tube fixing part 51 of the auxiliary locking member 5 is similar to the shape of the inner tube fixing part 41 of the locking member 4. The outer tube fixing part 51 shown in Figs. 1 to 3 and 6 can slide relative to the outer tube 31 along the second extension direction d2 in which the tubular member 3 extends. Although not shown, the outer tube fixing part 51 may have a structure that does not allow it to slide relative to the outer tube 31.

[0042] The connecting portion 52 of the auxiliary locking member 5 extends from the outer tube fixing portion 51 in the lateral direction of the tubular member 3 .

[0043] The auxiliary locking portion 53 is connected to the outer tube fixing portion 51 via the connecting portion 52. The auxiliary locking portion 53 has a shape capable of clamping the outer tube 31 of the tubular member 3. In the example shown in FIG. 6, the auxiliary locking portion 53 has a cylindrical shape with a part missing. The inner diameter w3 of the auxiliary locking portion 53 is determined so that the outer tube 31 can be clamped by the auxiliary locking portion 53. The outer tube 31 of the second tubular member 3b is inserted into the auxiliary locking portion 53 having a cylindrical shape with a part missing, and the auxiliary locking portion 53 clamps the outer tube 31 of the second tubular member 3b, whereby the auxiliary locking portion 53 can lock the second tubular member 3b.

[0044] Next, the operation of this embodiment having the above configuration will be described.

[0045] (Function of usage conditions) First, the operation of the drainer 1 in use as shown in Figs. 1 to 3 will be described. As described above, in the drainer 1 in use as shown in Figs. 1 to 3, the pair of mounting fixtures 2 extend in the first extension direction d1. The dimensions of the multiple tubular members 3 in the second extension direction d2 are adjusted to a length suitable for using the drainer 1 by drawing out the inner tube 32 from the outer tube 31. The engaging portion 43 of the locking member 4 and the auxiliary engaging portion 53 of the auxiliary locking member 5 engage the second tubular member 3b. The drainer 1 in use can be placed on a sink or the like, and wet items can be placed on the multiple tubular members 3 to drain the wet items.

[0046] 1 and 2 show an example in which the locking portion 43 is in contact with the inner pipe attachment 211 as an example of the use of the draining device 1 in the use state. However, the arrangement of the locking portion 43 in the use state is not limited to this. As shown in FIG. 7, the locking portion 43 in the use state may lock the tubular member 3 at the boundary portion 33 of the tubular member 3 that straddles the inner pipe 32 and the outer pipe 31. In this case, the position of the locking member 4 relative to the second tubular member 3b is adjusted by sliding the inner pipe fixing portion 41 of the locking member 4 relative to the inner pipe 32 along the second extension direction d2. Thereby, the locking portion 43 is moved to the boundary portion 33 of the tubular member 3 that straddles the inner pipe 32 and the outer pipe 31. Then, the locking portion 43 locks the tubular member 3 at this boundary portion 33.

[0047] (Storage state effect) Next, the operation of changing the drainer 1 from the usage state shown in Figures 1 to 3 or 7 to the storage state shown in Figures 11 and 12 will be described. First, the locking member 4 is rotated to disengage the engaging portion 43 from the second tubular member 3b. Then, the auxiliary locking member 5 is rotated to disengage the auxiliary engaging portion 53 from the second tubular member 3b.

[0048] Also, as shown in FIG. 7, when the engaging portion 43 engages the tubular member 3 at the boundary portion 33 spanning the inner tube 32 and the outer tube 31, the locking member 4 is slid relative to the first tubular member 3a until the locking member 4 comes into contact with the inner tube mounting fixture 211.

[0049] Next, the inner tube 32 is slid relative to the outer tube 31 to house the inner tube 32 within the outer tube 31, thereby shortening the dimension of each tubular member 3 in the second extension direction d2. As an example, the dimension of the tubular member 3 in the second extension direction d2 can be shortened until the inner pipe fixing portion 41 contacts both the outer tube 31 and the inner pipe attachment 211.

[0050] Next, the water draining device 1 is wound up. The water draining device 1 can be wound up around an axis parallel to the second stretching direction d2, for example, as shown in Figs. 8 and 9. In other words, the water draining device 1 is wound up so as to form a spiral when viewed from the side, as shown in Fig. 9. However, the manner in which the water draining device 1 is wound up is not limited to the manner shown in Figs. 8 and 9. For example, the entire water draining device 1 may be wound up, or only a part of the water draining device 1 may be wound up. Moreover, instead of being wound up, the water draining device 1 may be folded up so as to form a Z shape when viewed from the side.

[0051] Next, the locking member 4 is rotated to lock the tubular members 3 other than the first tubular member 3a by the locking portion 43. In addition, the auxiliary locking member 5 is rotated to lock the tubular members 3 other than the first tubular member 3a by the auxiliary locking portion 53. This allows the draining device 1 to be placed in the stored state shown in Figures 10 and 11.

[0052] As shown in Figs. 10 and 11, when the draining device 1 is in the stored state, the tubular member 3 locked by the locking portion 43 and the auxiliary locking portion 53 is determined by the overall shape of the draining device 1 when it is wound or folded, depending on the manner in which the draining device 1 is wound or folded. As an example, when the draining device 1 is in the stored state, the tubular member 3 locked by the locking portion 43 and the auxiliary locking portion 53 is determined so that the draining device 1 can easily maintain the stored state. In the example shown in Figs. 10 and 11, the locking portion 43 locks a third tubular member 3c different from the second tubular member 3b. In the stored state shown in Figs. 10 and 11, the first tubular member 3a is one tubular member to which the inner pipe fixing portion 41 is fixed, and the third tubular member 3c is another tubular member locked by the locking portion 43. The auxiliary locking portion 53 also locks the third tubular member 3c to which the locking portion 43 is locked.

[0053] Fig. 12 is an enlarged view showing a portion where the locking part 43 locks the third tubular member 3c in the drainer 1 in the stored state shown in Figs. 10 and 11. In the example shown in Fig. 12, the dimension of the third tubular member 3c in the second extension direction d2 is shortened by sliding the inner pipe 32 relative to the outer pipe 31. In this case, the inner pipe fixing part 41 contacts both the outer pipe 31 and the inner pipe attachment 211.

[0054] The draining device 1 in the stored state is hung with one of the pair of mounting fixtures 2 facing upward and the other facing downward by hanging the hanging part 23 on a hook or the like provided on the wall of the house. The draining device 1 in the stored state shown in Figures 10 and 11 is hung with the inner pipe mounting fixture 211 facing downward and the outer pipe mounting fixture 212 facing upward by hanging the hanging part 23 on a hook or the like provided on the wall of the house.

[0055] Next, a description will be given of how to return the drainer 1 in the stored state shown in Figures 10 and 11 to the usage state shown in Figures 1 to 3. The usage state basically follows the reverse procedure to the above-mentioned storage state.

[0056] First, in the drainer 1 in the stored state shown in Figures 10 and 11, the locking member 4 is rotated to release the engagement of the engagement portion 43 with the third tubular member 3c. Also, the auxiliary locking member 5 is rotated to release the engagement of the auxiliary engagement portion 53 with the third tubular member 3c.

[0057] Next, the water drainer 1 in the rolled up state is unfolded so that the pair of mounting fixtures 2 are stretched in the first stretching direction d1.

[0058] Next, the locking member 4 is rotated to lock the second tubular member 3b into the locking portion 43. Furthermore, the auxiliary locking member 5 is rotated to lock the second tubular member 3b into the auxiliary locking portion 53. This allows the draining device 1 to be in the usage state shown in Figures 1 to 3.

[0059] As described above, according to the present embodiment, the draining device 1 is stably maintained in the stored state in which the dimensions of the draining device 1 are reduced by the engagement of the engagement portion 43 of the locking member 4 with the tubular member 3 in the stored state. In particular, the draining device 1 is stably maintained in the wound-up state.

[0060] Here, the effect of the engaging portion 43 having the first engaging portion 431 and the second engaging portion 432 will be described in comparison with a comparative example. As a comparative example, consider a draining device 1 equipped with a locking member 4 in which the engaging portion 43 has a portion that engages the inner tube 32, but does not have a portion that engages the outer tube 31. Fig. 13 is an enlarged view of the draining device 1 of the comparative example in the stored state, showing the portion where the engaging portion 43 engages the tubular member 3.

[0061] In order for the locking portion 43 to stably lock the tubular member 3, it is preferable that the contact area between the locking portion 43 and the tubular member 3 when the locking portion 43 is locked to the tubular member 3 is large. For this purpose, it is preferable that the dimension of the locking portion 43 in the second stretching direction d2 is large. Here, if the dimension w4 of the locking portion 43 in the second stretching direction d2 in the comparative example is increased, the dimension of the portion of the inner tube 32 that is not accommodated in the outer tube 31 in the stored state in the second stretching direction d2 increases by the amount of the increase in the dimension w4 of the locking portion 43, making it difficult to shrink the tubular member 3.

[0062] In contrast, according to the present embodiment, the locking portion 43 has the second locking portion 432 capable of locking the inner tube 32, and also has the first locking portion 431 capable of locking the outer tube 31, so that the dimension w5 in the second extension direction d2 of the second locking portion 432 shown in Fig. 12 can be kept small. Therefore, the dimension in the second extension direction d2 of the inner tube 32 housed in the outer tube 31 in the stored state can be increased, and the tubular member 3 can be further compressed.

[0063] In addition, the draining device 1, whose engaging portion 43 has a first engaging portion 431 and a second engaging portion 432, has its stored state stably maintained by the locking member 4, especially when the draining device 1 in the stored state is hung by the hanging portion 23.

[0064] In particular, by making the force with which the first locking portion 431 pinches the outer tube 31 sufficiently strong when the first locking portion 431 locks the outer tube 31, and by making the force with which the second locking portion 432 pinches the inner tube 32 sufficiently strong when the second locking portion 432 locks the inner tube 32, the positional relationship between the inner tube 32 and the outer tube 31 can be determined via the locking portion 43 in the stored state, and sliding of the inner tube 32 relative to the outer tube 31 can be suppressed. In other words, even when the draining device 1 in the stored state is hung by the hanging portion 23, the inner tube 32 and the outer tube 31 are fixed by the locking member 4, so that the inner tube 32 located below will not drop relative to the outer tube 31 (see FIG. 10).

[0065] Furthermore, according to this embodiment, in the water draining device 1, when in use, the engaging portion 43 of the locking member 4 engages the second tubular member 3b, thereby enabling the position of the locking member 4 relative to the tubular member 3 to be determined at a position that does not interfere with the use of the water draining device 1.

[0066] In particular, by making the clamping force of the first locking portion 431 around the outer tube 31 sufficiently strong when the first locking portion 431 locks the outer tube 31, and by making the clamping force of the second locking portion 432 around the inner tube 32 sufficiently strong when the second locking portion 432 locks the inner tube 32, the positional relationship between the inner tube 32 and the outer tube 31 can be determined via the locking portion 43 when in use, and sliding of the inner tube 32 relative to the outer tube 31 can be suppressed.

[0067] Moreover, the draining device 1 according to this embodiment includes an auxiliary locking member 5 in addition to the locking member 4. In the stored state, the engaging portion 43 of the locking member 4 engages the tubular member 3, and the auxiliary engaging portion 53 of the auxiliary locking member 5 engages the tubular member 3, so that the draining device 1 can be stably maintained in the stored state with its reduced dimensions. In particular, the draining device 1 can be stably maintained in the rolled-up state.

[0068] Furthermore, in the water draining device 1 of this embodiment, when in use, the auxiliary engaging portion 53 of the auxiliary locking member 5 engages the tubular member 3, so that the position of the auxiliary locking member 5 relative to the tubular member 3 can be determined at a position that does not interfere with the use of the water draining device 1.

[0069] The aspects of the present invention are not limited to the above-described embodiment, but include various modifications that may be conceived by a person skilled in the art, and the effects of the present invention are not limited to the above-described contents. In other words, various additions, modifications, and partial deletions are possible within the scope of the conceptual idea and intent of the present invention derived from the contents defined in the claims and their equivalents.
