Below, an example of an embodiment of an assembled chair according to the present disclosure will be described in detail with reference to Figures 1 to 12.

Figure 1 is a perspective view of the draining device 1 in use. Figure 2 is a plan view of the draining device 1 shown in Figure 1. Figure 3 is a front view of the draining device 1 shown in Figure 1, in which of a pair of fittings 2 described later, an outer tube fitting 212 is shown at the front and an inner tube fitting 211 is shown at the back. The draining device 1 of the present invention can be in a use state in which dishes and the like can be placed as shown in Figures 1 to 3, and in a storage state suitable for storage as shown in Figures 10 and 11, which will be described later.

The draining device 1 according to the present disclosure includes a pair of mounting fixtures 2 and a number 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, and the mounting fixtures 2 are bent, allowing the device to be freely switched between a use state and a storage state.

Next, we will further explain each component of the water draining device 1.

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

The mounting fixture 2 has a plurality of mounting portions 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 portions 21 each have a recess 21a into which the tip of the tubular member 3 is inserted. When the draining device 1 is deployed in a usable state as shown in Figs. 1 to 3, the plurality of mounting portions 21 are aligned in the first extension direction d1. The mounting fixture 2 also has a connection portion 22 that connects the plurality of mounting portions 21 together. When the draining device 1 is deployed in a usable state as shown in Figs. 1 to 3, the mounting portions 21 and the connection portions 22 are aligned alternately in the first extension direction d1, and the mounting portions 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 portions 21 and eight connection portions 22.

The constituent material of each mounting fixture 2 will now 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 Figures 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 that allows the two mounting portions 21 located on either side of the connection portion 22 to come into contact with each other by bending the connection portion 22. The flexible material used as the material for the mounting fixture 2 is, for example, a flexible material such as silicone rubber.

At least one of the pair of mounting fixtures 2 is fitted with a hanging part 23 for suspending the draining device 1. In the example shown in Figures 1 to 3, the hanging part 23 is fitted to the inner pipe mounting fixture 211, and the hanging part 23 is not fitted to the outer pipe mounting fixture 212. Although not shown, the hanging part 23 may be fitted to the outer pipe mounting fixture 212, and the hanging part 23 may not be fitted to the inner pipe mounting fixture 211. Also, the hanging part 23 may be fitted to both the outer pipe mounting fixture 212 and the inner pipe mounting fixture 211.

The hanging part 23 is a part that can be hung on a hook or the like provided on the wall of a house 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 Figures 1 to 3, the hanging part 23 is an arc-shaped part that is connected to the mounting part 21 at both ends. As one example, the hanging part 23 is molded integrally with the mounting part 21 and the connection part 22 of the mounting fixture 2.

Next, the tubular member 3 will be described. As described above, the water draining device 1 comprises 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 the mounting portions 21 of the mounting fixtures 2. As shown in Figures 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.

When the draining device 1 is deployed in a usable state, the first extension direction d1 in which the attachment 2 extends and the 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 Figures 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, wet items can be drained by placing them on the multiple tubular members 3.

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 at least a portion of the inner tube 32 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 to change the dimensions of the water draining device 1 in the second extension direction d2.

As shown in FIG. 2, the outer tube 31 of the tubular member 3 has an axis L1 that extends through the center of the outer tube 31. The inner tube 32 of the tubular member 3 has an axis L2 that extends through the center of the inner tube 32, and the axis L1 and the axis L2 extend collinearly along the second extension direction d2.

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 part that prevents the inner tube 32 from slipping out of the outer tube 31. As an example, the slip-out prevention part 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 engages 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.

When at least one of the multiple tubular members 3 is provided with a slip-out prevention portion in this manner, 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. The inner tube 32 may also 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 dimensions of the draining device 1 in the second extension direction d2 in the usage state can be adjusted. This allows, for example, when placing the draining device 1 on a sink, the dimensions of the draining device 1 in the second extension direction d2 to be adjusted to match the size of the sink.

The tubular member 3 has a strength sufficient to withstand the weight of a wet object 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.

In this embodiment, the water draining device 1 further includes a locking member 4. The locking member 4 has an inner tube fixing portion 41 fixed to the inner tube 32 of one tubular member, and a locking portion 43 connected via a connecting portion 42 extending from the inner tube fixing portion 41 in the lateral direction of the tubular member 3 to lock the other tubular member. In the example shown in Figures 1 to 3, the first tubular member 3a located outermost in the first extension direction d1 among the multiple tubular members 3 is the one tubular member to which the inner tube fixing portion 41 is fixed. Also, in the example shown in Figures 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 locked to the locking portion 43.

Figure 4 is a perspective view showing the locking member 4. Figure 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 Figure 4, the inner tube fixing part 41 has a cylindrical shape. The inner tube 32 of the first tubular member 3a passes through the inner tube fixing part 41, which has a cylindrical shape, and the inner tube fixing part 41 is fixed to the inner tube 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 tube fixing part 41.

The inner tube fixing portion 41 shown in Figures 1 to 4 is fixed to the inner tube 32 so as to be slidable along the second extension direction d2. Although not shown, the inner tube fixing portion 41 may have a structure that does not allow it to slide relative to the inner tube 32.

The locking member 4 also has a connecting portion 42 that extends from the inner tube 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.

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.

The locking portion 43 has a shape that can clamp the tubular member 3. In the example shown in FIG. 4, the locking portion 43 has a cylindrical shape with a portion of the cylindrical shape missing. The second tubular member 3b is inserted into the locking portion 43, which has a cylindrical shape with a portion of the cylindrical shape missing, and the locking portion 43 can clamp the second tubular member 3b, thereby locking the second tubular member 3b.

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.

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.

Figure 4 shows the axis L1 of the outer tube 31 of the second tubular member 3b that is engaged with the first engaging portion 431. Also, Figure 4 shows the axis L2 of the inner tube 32 of the second tubular member 3b that is engaged with the second engaging portion 432.

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 to the first locking portion 431 and the axis L2 of the inner tube 32 locked to 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.

Figure 5 is an enlarged view of the portion where the locking portion 43 locks the second tubular member 3b in the water draining device 1 deployed in the use state shown in Figures 1 to 3. In Figure 5, for the inner pipe attachment 211, only the attachment portion 21 to which the first tubular member 3a is fixed, the attachment portion 21 to which the second tubular member 3b is fixed, and the connection portion 22 that connects these attachments 2 are shown, and other portions are omitted. In the example shown in Figure 5, the locking portion 43 is in contact with the inner pipe attachment 211. In addition, 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.

The draining device 1 according to this embodiment further includes an auxiliary locking member 5. The auxiliary locking member 5 has an outer tube fixing portion 51 fixed to the outer tube 31 of the first tubular member 3a, and an auxiliary locking portion 53 that is 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 Figures 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 Figures 1 and 2, the auxiliary locking portion 53 locks the second tubular member 3b, which is located next to the first tubular member 3a in the first extension direction d1, among the multiple tubular members 3.

Figure 6 is a perspective view showing the auxiliary locking member 5. In Figure 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 Figures 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 prevents it from sliding relative to the outer tube 31.

The connecting portion 52 of the auxiliary locking member 5 extends laterally from the outer tube fixing portion 51 to the tubular member 3.

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 that can hold 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 portion missing. The inner diameter w3 of the auxiliary locking portion 53 is determined so that the auxiliary locking portion 53 can hold the outer tube 31. The auxiliary locking portion 53 can lock the second tubular member 3b by inserting the outer tube 31 of the second tubular member 3b into the auxiliary locking portion 53, which has a cylindrical shape with a portion missing, and holding the outer tube 31 of the second tubular member 3b with the auxiliary locking portion 53.

Next, we will explain the operation of this embodiment with such a configuration.

(Effect of state of use)
First, the operation of the draining device 1 in use as shown in Figures 1 to 3 will be described. As described above, in the draining device 1 in use as shown in Figures 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 draining device 1 by pulling 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 draining device 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 water from the wet items.

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 use. However, the arrangement of the locking portion 43 in use is not limited to this. As shown in FIG. 7, the locking portion 43 in use may lock the tubular member 3 at the boundary portion 33 that straddles the inner pipe 32 and the outer pipe 31 of the tubular member 3. In this case, the inner pipe fixing portion 41 of the locking member 4 is slid along the second extension direction d2 relative to the inner pipe 32 to adjust the position of the locking member 4 relative to the second tubular member 3b. This moves the locking portion 43 to the boundary portion 33 that straddles the inner pipe 32 and the outer pipe 31 of the tubular member 3. Then, the locking portion 43 locks the tubular member 3 at this boundary portion 33.

(Operation in storage state)
Next, the operation of changing the draining device 1 from the use 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.

Also, as shown in FIG. 7, when the engaging portion 43 engages the tubular member 3 at the boundary portion 33 that straddles 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 attachment 211.

Next, the inner tube 32 is slid relative to the outer tube 31, and the inner tube 32 is housed within the outer tube 31, 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 tube fixing portion 41 contacts both the outer tube 31 and the inner tube attachment 211.

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 extension direction d2, for example, as shown in Figures 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 Figure 9. However, the manner in which the water draining device 1 is wound up is not limited to the manner shown in Figures 8 and 9. For example, the entire water draining device 1 may be wound up, or only a portion 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.

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

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 tube fixing portion 41 is fixed, and the third tubular member 3c is another tubular member locked by the locking portion 43. Additionally, the auxiliary locking portion 53 similarly locks the third tubular member 3c that is locked by the locking portion 43.

Figure 12 is an enlarged view of the portion where the locking portion 43 locks the third tubular member 3c in the draining device 1 in the stored state shown in Figures 10 and 11. In the example shown in Figure 12, the inner tube 32 is slid relative to the outer tube 31 to shorten the dimension of the third tubular member 3c in the second extension direction d2. In this case, the inner tube fixing portion 41 is in contact with both the outer tube 31 and the inner tube attachment 211.

When the draining device 1 is in the stored state, it 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. When the draining device 1 is in the stored state shown in Figures 10 and 11, it 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.

Next, we will describe 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 storage state described above.

First, in the draining device 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. In addition, the auxiliary locking member 5 is rotated to release the engagement of the auxiliary engagement portion 53 with the third tubular member 3c.

Next, the rolled-up draining device 1 is unfolded so that the pair of mounting fixtures 2 are extended in the first extension direction d1.

Next, the locking member 4 is rotated to lock the second tubular member 3b into the locking portion 43. The auxiliary locking member 5 is also 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.

As described above, according to this embodiment, the draining device 1 is stably maintained in a 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 a rolled-up state.

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

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 extension direction d2 is large. Here, if the dimension w4 of the locking portion 43 in the second extension direction d2 in the comparative example is increased, the dimension in the second extension direction d2 of the portion of the inner tube 32 that is not contained within the outer tube 31 in the stored state 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.

In contrast, according to the present embodiment, the locking portion 43 has a second locking portion 432 capable of locking the inner tube 32, and a 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.

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

In particular, by making the clamping force of the first locking portion 431 on the outer tube 31 strong enough when the first locking portion 431 locks the outer tube 31, and by making the clamping force of the second locking portion 432 on the inner tube 32 strong enough 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 the 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).

In addition, according to this embodiment, in the draining device 1, when in use, the engaging portion 43 of the locking member 4 engages the second tubular member 3b, so that the position of the locking member 4 relative to the tubular member 3 can be determined at a position that does not interfere with the use of the draining device 1.

In particular, by making the clamping force of the first locking portion 431 on 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 on 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 usage state, and sliding of the inner tube 32 relative to the outer tube 31 can be suppressed.

The draining device 1 according to this embodiment also includes an auxiliary locking member 5 in addition to the locking member 4. In the stored state, the locking portion 43 of the locking member 4 locks the tubular member 3, and the auxiliary locking portion 53 of the auxiliary locking member 5 locks the tubular member 3, so that the draining device 1 can be stably maintained in a stored state with reduced dimensions. In particular, the draining device 1 can be stably maintained in a rolled-up state.

In addition, in the draining device 1 according to this embodiment, when in use, the auxiliary locking portion 53 of the auxiliary locking member 5 locks the tubular member 3, so that the position of the auxiliary locking member 5 relative to the tubular member 3 can be set to a position that does not interfere with the use of the draining device 1.

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 that does not deviate from the conceptual idea and intent of the present invention derived from the contents defined in the claims and their equivalents.
