Description

The present invention relates primarily to multi-level bunks installed on ships.

Conventionally, a three-level bed has been installed in the accommodation area of a ship (Patent Document 1). In recent years, along with the demand for comfort in the living quarters, labor-saving on ships has progressed, so two-level bunks are becoming mainstream. On the other hand, ships are diversifying their missions, and it is planned that the number of crew members will temporarily increase depending on the missions assigned. In other words, when a specific mission was assigned, it was scheduled to have a temporary crew on board in addition to the original crew. Therefore, there is a demand for a multi-level bed that is normally used as a two-level bed and that can be changed to a three-level bed as needed.

Japanese Utility Model Laid-Open No. 4-249

A three-tier bed requires three sets of bed frames, while a two-tier bed only requires two sets of bed frames. Therefore, when using a conventional three-level bed as a two-level bed, it is necessary to remove a set of bed frames that are no longer needed and store them in another location. And you need work space and storage space for that. In other words, there is the problem that a set of bed frames that are no longer needed must be pulled out, transported, and stored. It is not easy to secure such a space in a ship with limited capacity.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a multi-level bed whose configuration can be changed and which does not require work space and storage space for changing the configuration. .

It is a figure shown along time series.

When removing the support hardware 9 from the receiving hardware 6, first, the bolt 10 (not shown in FIG. 7) is removed. Then, as shown in FIG. 7(A), the bolt 11 is loosened and the support hardware 9 is slid in the direction indicated by the arrow in FIG. 7(A) to the position shown in FIG. 7(B). After that, the support hardware 9 is rotated clockwise around the bolt 11, that is, in the direction indicated by the arrow in FIG. 7(B) by 90°. As a result, as shown in FIG. 7(C), the support hardware 9 is removed from the receiving hardware 6, and the upper bed frame 3 can be moved vertically.

Finally, the procedure for changing the configuration of the multi-level bed 1 will be described with reference to FIGS. 8(A) to 8(D). 8A to 8D are cross-sectional views showing the multi-bed 1 cut along the plane indicated by line II in FIG. FIG. 10 is a diagram showing a procedure for moving from 1 to a high position in chronological order.

The multi-level bed 1 shown in FIG. 8(A) is in a state of being used as a two-level bed. The upper bed frame 3 and the middle bed frame 4 are locked at their respective low positions. That is, the upper bed frame 3 is locked to the leg members 2 via the second receiving hardware 6 from the top. The middle bed frame 4 is locked to the leg member 2 via a bracket 6 arranged at the bottom.

In this state, the bolts 10 fixing the receiving metal fittings 6 to the supporting metal fittings 9 are removed, and the nuts 12 (not shown in FIG. 8) fixing the upper bed frame 3 to the receiving metal fittings 6 are loosened, and the above-described procedure is carried out. , the support hardware 9 is removed from the receiving hardware 6 . As a result, the locked state of the upper bed frame 3 is released. When the locked state of the upper bed frame 3 is released, the upper bed frame 3 can be moved upward as shown in FIG. 8(B).

If the upper bed frame 3 is moved from the position shown in FIG. 8A to the position shown in FIG. Therefore, the head-side end of the upper bed frame 3 is made slightly higher or slightly lower than the foot-side end, that is, the upper bed frame 3 is tilted slightly, and the upper bed frame 3 is placed as shown in FIG. It is moved from the position shown in (A) to the position shown in FIG. 8(B).

After that, the support metal fittings 9 attached to the upper bed frame 3 are inserted into the receiving metal fittings 6 arranged at the highest position in the leg members 2, and the nuts 12 (not shown in FIG. 8) and the bolts 10 are tightened. As shown in (C), the upper bed frame 3 is locked at the high position. Through the above process, the movement of the upper bed frame 3 from the low position to the high position is completed.

Through a similar procedure, the middle bed frame 4 can be moved from the low position to the high position. That is, the middle bed frame 4, which has been locked to the leg member 2 via the metal fitting 6 arranged at the lowest position, is moved to the leg member via the metal fitting 6 arranged second from the bottom. 2 can be locked. Then, as shown in FIG. 8(D), by attaching a safety fence 7 (not shown in FIG. 8) and a safety fence 8 to the lower bed frame 5, the multi-level bed 1 can be changed from the configuration shown in FIGS. The bed 1 is modified to be used as a three-tier bed.

Further, by performing the operations in the reverse order of the above, the multi-level bed 1 can be changed from being used as a three-level bed to being used as a two-level bed. The above operation is performed by a total of three workers: two workers who temporarily hold the upper bed frame 3 or the middle bed frame 4 and raise and lower it, and one worker who attaches and detaches the support hardware 9. is enough. In addition, since the time for the worker to hold the upper bed frame 3 or the middle bed frame 4 or the time to raise and lower it is short, the physical burden on the worker is small. Also, no special machines or instruments are required for the above operations.

In the above work, the upper bed frame 3 or the middle bed frame 4 is moved within the space formed between the four leg members 2, so a large work space is not required. When the multi-level bed 1 is used as a two-level bed, that is, even when the lower bed frame 5 is not used, the lower bed frame 5 is not removed, so there is no need to prepare a space for storing the lower bed frame 5.例文帳に追加

As described above, the multi-level bed 1 according to the present embodiment does not require work space and storage space due to the change in configuration. Therefore, it can be installed in a ship's accommodation area where space is limited, and can be easily changed within the accommodation area.

However, the technical scope of the present invention is not limited by the above embodiments. The present invention can be freely modified or improved within the scope of the technical idea described in the claims.

For example, in the above embodiment, the multi-level bed 1 that can be used as a two-level bed or a three-level bed was illustrated, but the technical scope of the present invention is not limited to a multi-level bed that can be used as a two-level bed or a three-level bed. . For example, the multi-level bed according to the present invention may be a multi-level bed that can be configured between a 4-level bed, a 3-level bed, or a 2-level bed.

Although the lower bed frame 5 is directly fixed to the leg members 2 in the above embodiment, the lower bed frame 5 is not limited to being directly fixed to the leg members 2 . Like the upper bed frame 3 and the middle bed frame 4, the lower bed frame 5 may be locked to the leg members 2 via the receiving metal fittings 6 and the support metal fittings 9.

In the present embodiment, the leg members 2 are made of angle steel, but the present invention is not limited to having leg members made of angle steel. The leg members may be members of other shapes, such as circular tubes or rectangular tubes.

In the above, an example is shown in which the bolt 10 is provided to prevent the support metal fitting 9 from falling off from the receiving metal fitting 6, but the bolt 10 is an optional component. In other words, the multi-level bed according to the present invention may not have screw elements corresponding to the bolts 10 . Moreover, the multi-level bed according to the present invention may be provided with a drop-off preventing member instead of the bolt 10 .

The features of the appearance of the multi-level bed 1 shown in the above embodiment are merely examples. The appearance of the multi-level bed according to the present invention can be freely changed within the scope of the technical idea described in the claims.
