Description

TECHNICAL FIELD The present invention relates primarily to multi-tier bunks installed on ships.

Conventionally, the living quarters of ships have been equipped with three-tiered berths (Patent Document 1). In recent years, as living quarters have become more comfortable and ships have become more labor-saving, two-tier bunks have become mainstream. On the other hand, the missions of ships are diversifying, and the number of crew members is expected to temporarily increase depending on the assigned mission. In other words, when a specific mission is assigned, a temporary crew is scheduled to be on board in addition to the specific crew. Therefore, there is a demand for a multi-tiered bed that can be normally used as a two-tiered bed and can be changed to a three-tiered bed if necessary.

Utility Model Publication No. 4-249

A three-tier bed requires three sets of bed frames, while a two-tier bed requires two sets of bed frames. Therefore, when using a conventional three-tiered bed as a two-tiered bed, it is necessary to remove one set of unnecessary bed frames and store them in another location. This requires work space and storage space. That is, there is a problem in that a space is required to pull out, transport, and store a set of unnecessary bed frames. Securing such space on a ship with limited capacity is not easy.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a multi-tiered bed that can change its shape and does not require work space and storage space accompanying the shape change. .

In order to achieve the above object, the multi-tiered bed according to the present invention includes a plurality of bed frames arranged vertically apart from each other, and a bed frame arranged at the four corners of the bed frame and fixed at the installation location. It has four leg members that support the frame. The bed frame includes support metal fittings bolted to the bed frame at the four corners thereof, and receiving metal fittings fixed to each of the four leg members to lock the support metal fittings. In each of the leg members, the receiving hardware is arranged at a plurality of locations having different heights as measured from the installation location, and the number of receiving hardware provided in each of the leg members is greater than the number of bed frames.

The multi-tiered bed may include a plurality of bed frames that are locked to the leg members via support hardware and receiving hardware, and a single bed frame that is fixed to a specific height of the leg members.

The multi-tier bed may include an upper bed frame and a middle bed frame that are locked to the leg members via support hardware and receiving hardware, and a lower bed frame that is fixed to a specific height of the leg members.

A multi-tiered bed has two sets of brackets that lock the upper bed frame at two positions, high or low, and two sets of brackets that lock the middle bed frame at two positions, high or low. It is also possible to have a set of

The multi-tiered bed may be one that can be changed by selecting between a form used as a two-tiered bed and a form used as a three-tiered bed.

The multi-tiered bed may include a bolt that is screwed into a female screw provided on the receiving metal fitting and is inserted into a through hole provided in the supporting metal fitting to prevent the supporting metal fitting from falling off from the receiving metal fitting.

Since the multi-tiered bunk according to the present invention does not require work space and storage space due to a change in form, it can be installed in the living quarters of a ship where space is limited. Work to change the configuration can be carried out in living quarters where space is limited.

Hereinafter, the structure and operation of the multi-tiered bed according to the embodiment of the present invention will be explained in detail with reference to the drawings. In addition, in each drawing, the same or equivalent parts are given the same reference numerals.

FIG. 1 is a perspective view showing the outer shape of a multi-tiered bed 1 according to an embodiment of the present disclosure. As shown in FIG. 1, the multi-tiered bed 1 includes four leg members 2 fixed at an installation location, an upper bed frame 3, a middle bed frame 4, and a lower bed frame 5, which are arranged vertically apart from each other. It is equipped with A mattress and bedding (not shown) are placed on the upper bed frame 3, the middle bed frame 4, and the lower bed frame 5. In addition, below, the upper bed frame 3, the middle bed frame 4, and the lower bed frame 5 may be collectively referred to as "bed frames 3, 4, and 5." Further, as shown in FIG. 1, in this embodiment, the leg member 2 is made of angle iron, and the bed frames 3, 4, and 5 are arranged on the inner corner side of the angle iron.

As shown in FIG. 1, the four leg members 2 are arranged at the four corners of the bed frames 3, 4, and 5, and the bed frames 3, 4, and 5 are supported by the four leg members 2. The lower bed frame 5 is fixed at a specific height of the leg members 2. The upper bed frame 3 and the middle bed frame 4 are respectively locked to the leg members 2 at either a high position or a low position. Further, receiving hardware 6 is fixed to the leg member 2 at a total of four locking positions: a high position and a low position of the upper bed frame 3, and a high position and a low position of the middle bed frame 4. Support hardware, which will be described later, is inserted into the receiving hardware 6, and the upper bed frame 3 and middle bed frame 4 are locked to the leg members 2 via the support hardware.

Note that FIG. 1 shows a state in which the multi-tiered bed 1 is used as a two-tiered bed, and the upper bed frame 3 and the middle bed frame 4 are locked to the leg members 2 at their respective low positions. Further, safety fences 7 and 8 are attached to the upper bed frame 3 and the middle bed frame 4. Safety fences 7 and 8 have been removed from the lower bed frame 5.

FIG. 2 is a front view of the multi-tiered bed 1 in a state where it is used as a two-tiered bed, that is, in the same state as shown in FIG. 1. As described above, in this state, the upper bed frame 3 and the middle bed frame 4 are locked at their respective low positions. In this case, a sufficient clearance above the upper bed frame 3 and the middle bed frame 4 is ensured. On the other hand, since the distance between the middle bed frame 4 and the lower bed frame 5 is close, the user cannot enter between the middle bed frame 4 and the lower bed frame 5.

FIG. 3 is a front view of the multi-tiered bed 1 in a state where it is used as a three-tiered bed. In this state, the upper bed frame 3 and the middle bed frame 4 are locked at their respective high positions. In this case, the clearance above the upper bed frame 3 and the middle bed frame 4 is smaller than that shown in FIG. 2, but the clearance necessary for the user to enter and exit is secured. On the other hand, since the distance between the middle bed frame 4 and the lower bed frame 5 is larger than that shown in FIG. 2, the user cannot fit between the middle bed frame 4 and the lower bed frame 5. I can do it. Further, when the multi-tiered bed 1 is used as a three-tiered bed, safety fences 7 and 8 are attached to the lower bed frame 5, as shown in FIG.

FIG. 4 is a cross-sectional view of the multi-tiered bed 1 taken along the plane indicated by line II in FIG. 2. As shown in FIG. As shown in FIG. 4, four receiving metal fittings 6 are fixed to each leg member 2. The upper bed frame 3 is locked to the leg member 2 via a receiving metal fitting 6 placed second from the top. The middle bed frame 4 is locked to the leg member 2 via a receiving metal fitting 6 disposed at the lowest position. The upper bed frame 3 and the middle bed frame 4 are also locked to two other leg members 2, which are not shown in FIG. 4, via metal fittings 6. That is, the upper bed frame 3 and the middle bed frame 4 are locked to the leg members 2 via the receiving hardware 6 at the four corners. Moreover, in the state shown in FIG. 4, the receiving metal fitting 6 placed at the highest position and the receiving metal fitting 6 placed second from the bottom are not used.

FIG. 5(A) is an enlarged view showing the periphery of the receiving metal fitting 6 located at the lower left of the upper bed frame 3 in FIG. FIG. 5(B) is a cross-sectional view showing the periphery of the receiving metal fitting 6 taken along the plane indicated by the line II--II in FIG. 5(A). 6(A) is a perspective view showing the outer shape of the receiving metal fitting 6, and FIG. 6(B) is a perspective view showing the outer shape of the supporting metal fitting 9 locked to the receiving metal fitting 6. FIG. 6(C) is a perspective view showing a state in which the support metal fitting 9 is attached to the receiving metal fitting 6.

The receiving metal fitting 6 is a member having an L-shaped cross section as shown in FIG. 5(B), and is fixed to the leg member 2 by welding. A gap is formed between the receiving hardware 6 and the leg member 2. Further, as shown in FIGS. 5(B) and 6(A), a caulking nut 6a is fixed to the receiving metal fitting 6.

As shown in FIGS. 5(A) and 5(B), a supporting metal fitting 9 is locked to the receiving metal fitting 6. As shown in FIGS. As shown in FIG. 6(B), the support hardware 9 includes a vertical surface material 9a and a horizontal surface material 9b coupled to the vertical surface material 9a. Further, a bracket 9c is provided between the vertical surface material 9a and the horizontal surface material 9b to reinforce the joint between the vertical surface material 9a and the horizontal surface material 9b. Furthermore, a long hole 9d is formed in the horizontal surface member 9b.

As shown in FIGS. 5(B) and 6(C), the vertical surface material 9a of the supporting hardware 9 is inserted into the gap formed between the receiving hardware 6 and the leg member 2. As shown in FIGS. Further, as shown in FIGS. 5A and 5B, the upper bed frame 3 is placed on the horizontal surface member 9b of the support hardware 9.

As shown in FIG. 5(B), a bolt 10 is screwed into a caulking nut 9a fixed to the receiving metal fitting 6. As shown in FIG. Further, the bolt 10 is inserted into a through hole 9e formed in the support hardware 9, and the tip of the bolt 10 is in contact with the leg member 2. With this configuration, the bolt 10 functions as a retainer to prevent the support metal fitting 9 from falling off from the receiving metal fitting 6.

A bolt hole (not shown) is formed in the upper bed frame 3, and a bolt 11 is inserted therethrough as shown in FIG. 5(A). Further, the bolt 11 is inserted into an elongated hole 9d (not shown in FIG. 5A) formed in the support hardware 9. As shown in FIG. 5(A), a nut 12 is screwed onto the tip of the bolt 11. By tightening the nuts 12, the upper bed frame 3 is fixed to the support hardware 9.

In this way, the upper bed frame 3 is locked to the leg member 2 via the receiving hardware 6 and the supporting hardware 9. Similarly, the upper bed frame 3 is locked to the leg members 2 at other corners as well. That is, the upper bed frame 3 is locked to the leg members 2 at the four corners via the receiving metal fittings 6 and the supporting metal fittings 9. Similarly, the middle bed frame 4 is also locked to the leg members 2 via the receiving metal fittings 6 and the supporting metal fittings 9.

Next, the procedure for removing the supporting hardware 9 from the receiving hardware 6 will be described with reference to FIGS. 7(A) to (C). 7(A) to (C) are arrow views of the supporting hardware 9 seen from the direction indicated by arrow P in FIG. 5(A), and show the steps for removing the supporting hardware 9 from the receiving hardware 6. FIG. 3 is a diagram shown in chronological order.

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

Finally, the procedure for changing the form of the multi-tiered bed 1 will be described with reference to FIGS. 8(A) to 8(D). 8(A) to (D) are cross-sectional views showing the multi-tiered bed 1 taken along the plane indicated by the line II in FIG. It is a figure which shows the procedure of moving from to a high position along a time series.

The multi-tiered bed 1 shown in FIG. 8(A) is in a state where it is used as a two-tiered 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 member 2 via the receiving metal fitting 6 placed second from the top. The middle bed frame 4 is locked to the leg member 2 via a receiving metal fitting 6 disposed at the lowest part.

In this state, remove the bolts 10 that fix the receiving hardware 6 to the supporting hardware 9, loosen the nuts 12 (not shown in FIG. 8) that fix the upper bed frame 3 to the receiving hardware 6, and perform the above-mentioned procedure. , 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).

Note that when the upper bed frame 3 is moved from the position shown in FIG. 8(A) to the position shown in FIG. 8(B) while keeping the upper bed frame 3 horizontal, the support metal fittings 9 interfere with the receiving metal fittings 6. Therefore, the end of the upper bed frame 3 on the head side is made slightly higher or lower than the end on the foot side, that is, the upper bed frame 3 is slightly tilted, and the upper bed frame 3 is adjusted as shown in FIG. It is moved from the position shown in (A) to the position shown in FIG. 8(B).

After that, the supporting metal fitting 9 attached to the upper bed frame 3 is inserted into the receiving metal fitting 6 arranged at the highest position in the leg member 2, and the nut 12 (not shown in FIG. 8) and the bolt 10 are tightened. As shown in (C), the upper bed frame 3 is locked at a 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 the same procedure, the middle bed frame 4 can be moved from the low position to the high position. In other words, the middle bed frame 4, which was locked to the leg member 2, is fixed to the leg member 2 via the receiving hardware 6 located at the lowest position, and the leg member 2 can be locked. As shown in FIG. 8(D), by attaching the safety fence 7 (not shown in FIG. 8) and the safety fence 8 to the lower bed frame 5, the multi-tiered bed 1 can be changed from the configuration shown in FIGS. Bed 1 is changed to a configuration in which it is used as a three-tiered bed.

Further, by performing the operations in the reverse order to the above, it is possible to change the multi-tiered bed 1 from a configuration in which it is used as a three-tiered bed to a configuration in which it is used as a two-tiered bed. In addition, the above operation was carried out by a total of three workers: two workers who temporarily held the upper bed frame 3 or middle bed frame 4 and raised and lowered it, and one worker who attached and removed the support hardware 9. It is enough if there is. Further, the time required for the worker to hold the upper bed frame 3 or the middle bed frame 4 or to raise and lower the bed frame 4 is short, so that the muscular burden on the worker is small. Further, no special machinery or equipment is required for the above work.

Furthermore, in the above work, the upper bed frame 3 or the middle bed frame 4 moves within the space formed between the four leg members 2, so a large work space is not required. Even when the multi-tiered bed 1 is used as a two-tiered bed, that is, 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.

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

For example, the multi-tiered bed according to the present invention may be a multi-tiered bed whose configuration can be changed between a four-tiered bed, a three-tiered bed, or a two-tiered bed.

In the above embodiment, it has been explained that the lower bed frame 5 is directly fixed to the leg members 2, but the lower bed frame 5 is not limited to being directly fixed to the leg members 2. Similarly to the upper bed frame 3 and the middle bed frame 4, the lower bed frame 5 may be locked to the leg member 2 via the receiving hardware 6 and the support hardware 9.

In this embodiment, the leg member 2 is made of angle iron, but the present invention is not limited to a leg member made of angle iron. The leg members may be constructed of members having other shapes, such as circular tubes or square tubes.

In the above example, the bolt 10 is provided in order to prevent the support metal fitting 9 from falling off the receiving metal fitting 6, but the bolt 10 is an optional component. That is, the multi-tiered bed according to the present invention may not include threaded elements corresponding to the bolts 10. Furthermore, the multi-tiered bed according to the present invention may be provided with a fall prevention member in place of the bolts 10.

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