DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for supporting a movable deck of a ship for supporting a deck used in a hold of a cargo ship or the like at a predetermined height.

[0002]

2. Description of the Related Art FIG. 20 shows a cross section of a cargo ship. The middle deck 102 installed in the hold 101 is represented by a solid line. In some cargo ships, the height position at which the middle deck 102 is installed in the hold 101 is determined in only one step, and the height position cannot be changed. In addition, the cargo is efficiently incorporated into the hold 101. For this reason, there is a type in which the height position can be changed. In FIG. 20, in addition to the middle deck 102 represented by a solid line, the middle deck 102 is also represented by a two-dot chain line, but this indicates a height position at which the middle deck 102 can be installed in the hold 101. It is of. In the hold 101, three height positions are set, and the middle deck 10 is located at the most appropriate height position among them according to the size of the cargo.
2 is supported.

[0003] As a conventional middle deck support device for supporting the middle deck at such a height position, for example, a structure shown in FIG. 21 is known. In the middle deck support device of FIG. 21, a recess 108 is provided in the hold wall surface 103. The arm member 104 is pivotally supported inside the recess 108. This arm member 104
Has a protruding state in which the tip end protrudes from the recess 108,
It is rotatably supported between the storage state stored in the recess 108 and the storage state. An operation cable 120 for storage is attached to a side surface of the arm member 104. By pulling the operation cable 120 for storage, the arm member 104 is pulled.
Is rotated so that the tip of the arm member 104 rises, and the arm member 104 is in the retracted state. A two-dot chain line in the figure represents the arm member 104 in the retracted state. When the storage operation cable 120 is loosened, the arm member 104 is rotated by its own weight so that the distal end thereof is lowered, and becomes in a protruding state. Middle deck 10
The lower end of the peripheral edge of the arm member 104 is in the protruding state.
, Whereby the middle deck 102 is supported at the height of the recess 108 in the hold 101. In addition,
In order to restrict the rotation range of the arm member 104,
08, two stoppers 109 are provided. The upper end of the storage operation cable 120 is connected to a driving device (not shown).

In this type of prior art, a container is supported by an arm member protruding from the hold side. For example, Japanese Patent Publication No. 61-32199, Japanese Patent Application Laid-Open No. 62-20789, and Showa 61-10069
There is one described in Japanese Patent No.

[0005] As another conventional technique, Japanese Utility Model Publication No.
There is one such as described in JP-A-41034. In this method, a car deck of a car carrier is raised and lowered by a lift car, and a height position supported in the hull is switched. In this conventional technique, a support arm is projected from a peripheral portion of a car deck, and the support arm is mounted on a support table at a predetermined height of a frame provided in a hull. As a result, the car deck is supported at the height of the support base. The support arm slides between a protruding position protruding from the periphery of the car deck and a storage position stored inside from the periphery of the car deck. Hydraulic cylinder,
A rack and pinion mechanism is used on the car deck side. Also, to change the height position of the car deck,
That is, a lift car is used for raising and lowering as described above.

[0006]

However, in the first of the above-mentioned prior arts, if the number of steps at the height position is increased, a corresponding number of intermediate deck support devices are required. For this reason, in the hold 101 in which multiple height positions are set, a large number of middle deck support devices are required.

[0007] For example, consider a case where one hold 101 is provided with 20 middle decks 102 and the installation height positions are provided in three steps. Assuming that the four corners of the quadrangular middle deck 102 are supported by the support devices, a total of 240 support devices are required in this case. Also, in response to this, the arm member 10
The same number of driving devices for projecting and storing 4 are required. Furthermore, if the arm members 104 are locked in the state of being stored in the concave portions 108, the same number of locking devices are required. In addition, a large amount of labor is required for the operation of projecting and storing the arm member 104, the operation of the driving device is complicated, and many operators are required.

[0008] Thus, each of the many support devices,
Incorporation into the hull requires a great deal of effort. For this reason, usually, a method is adopted in which a wall portion provided with a plurality of recesses 108 provided with a supporting device is unitized and manufactured as a part of the hull structure, and this is fitted into the hull structure. However, even if this method is adopted, much labor is required, and the operation of the driving device is still complicated.

In addition, a lot of labor is required for manufacturing, and the manufacturing cost increases. Furthermore, much labor is required for maintenance.

In the second prior art described above, a hydraulic cylinder and a rack and pinion mechanism are used as mechanisms for sliding the support arm from the projecting position to the storage position or from the storage position to the projection position. , And a lift car is used for raising and lowering the car deck. As described above, complicated or large-scale mechanisms and power are used, so that the operation is complicated and the manufacturing cost is increased, as in the above-mentioned first prior art. In addition, much labor is required for maintenance.

The object of the invention according to the present application is to provide a movable middle deck support device for a marine vessel which can reduce the manufacturing cost and the labor required for maintenance and operation of the drive device in view of the conventional problems. To provide.

[0012]

According to the present invention, arm members are provided on both sides of a middle deck for engaging with concave portions provided in a hold. And this arm member has a tip end portion projecting horizontally from the periphery of the middle deck,
The tip is rotatably supported between a stored state stored inside the periphery of the middle deck. Further, the center of gravity of the arm member is located near the center axis at the time of rotation. That is, the center of gravity of the arm member is substantially balanced about the central axis at the time of rotation.

[0013] With this configuration, a small driving force is required to move the arm member from the retracted state to the protruded state or from the protruded state to the retracted state. Further, since the arm members are provided on the middle deck side, when the height positions at which the middle deck is installed in the hold are provided in a plurality of stages, the number of support devices can be significantly reduced.

[0014]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a view showing an example of a movable middle deck support device for a ship according to the present invention. FIG.
FIG. 1A shows a state in which the arm member 4 is engaged with the recess 8, FIG.
(B) shows a state in which the engagement of the arm member 4 with the concave portion 8 is released.

First, the concept of a movable deck supporting device for a ship according to the present invention will be described with reference to FIG. In FIG. 1, reference numeral 1 denotes a hold of a cargo ship or the like, 3 denotes a hold wall surface, and 8 denotes a recess provided in the hold wall surface 3. 2 is this hold 1
A middle deck to be supported at a predetermined height position in the inside.

As shown in FIG. 1, the middle deck 2 has an arm member 4 which is rotatably supported by a shaft member 5 near the periphery of the middle deck 2. . The shaft member 5 is provided so as to penetrate the arm member 4. When the arm member 4 rotates, the shaft member 5 rotates integrally therewith. Although not shown in FIG. 1, the shaft member 5 is supported by a bearing provided on the middle deck 2.

The arm member 4 is formed in a substantially axially symmetrical shape, and the center of gravity is substantially balanced around the center of the shaft member 5. That is, the center of gravity of the arm member 4 shown in FIG. 1 is located near the center of the shaft member 5.

In FIG. 1 (a), the arm member 4 is in a protruding state in which the tip portion protrudes from the periphery of the middle deck 2 in the horizontal direction. The distal end of the arm member 4 is engaged with the concave portion 8 of the hold wall surface 3. FIG.
In FIG. 1B, the arm member 4 is in a state of being rotated about 90 degrees counterclockwise from the state of FIG. 1A. Then, the arm member 4 is in a stored state in which the tip portion is stored inside the peripheral edge of the middle deck 2. At this time, the arm member 4
Is disengaged from the recess 8. The rotatable range of the arm member 4 is restricted to a range of about 90 degrees by the stopper 10 provided on the middle deck 2 and the peripheral member 7 that borders the peripheral edge of the middle deck 2. Stopper 10
Is provided so that the rear end of the arm member 4 in the protruding state can be supported from below. The peripheral member 7 is
It is provided so as to extend downward from the peripheral edge of the upper surface of the middle deck 2. The receiving seat 9 in the recess 8 is provided on the hold wall surface 3 side. The portion of the arm member 4 that contacts the seat 9 is provided with an oilless metal 1 to reduce frictional resistance.
1 is affixed.

The recess 8 is provided in the hold wall surface 3 as shown in FIG. A receiving seat 9 is provided at the bottom, and guides 12 are provided on both sides of the receiving seat 9. Although not shown in FIG. 1, the recesses 8 are provided in a plurality of stages in the vertical direction of the hold wall surface 3. The middle deck 2 is supported at the most appropriate position among the height positions of the concave portions 8 provided in the plurality of stages in consideration of the load loaded in the hold.

As described above, since the center of gravity of the arm member 4 is substantially balanced around the center of the shaft member 5, and the center of gravity is located near the center of the shaft member 5, the middle deck 2 is not shown in FIG.
When the arm member 4 is in a relative height position relationship with the concave portion 8 as shown in FIG. 4B, the arm member 4 can be rotated from the retracted state to the projected state or from the projected state to the retracted state with a small driving force. it can.

The movable deck supporting device is provided not on the hold wall surface 3 but on the deck 2 side. Therefore, the number of movable middle deck support devices does not change regardless of the height position set. Therefore, when the height position is set in multiple stages, compared to the conventional middle deck support device,
The operation labor of the drive device, the production cost, the maintenance labor and the like can be greatly reduced.

Further, since there is no need to provide the arm member 4 or the like inside the concave portion 8, the structure of the concave portion 8 is simplified. For this reason, the depth dimension of the recess 8 can be reduced, and the hold 1 can be widened accordingly.

Next, the middle deck 2 supported at a certain height position is moved up and down to the vicinity of another height position, and the arm member 4 of the movable middle deck support device is projected at the height position after the lifting. A procedure for supporting the middle deck 2 at the height position after the lifting and lowering of the hold wall surface 3 will be described with reference to FIGS. 1 (a) and 1 (b).

On the wall surface 3 of the hold, there are two recesses 8 in the vertical direction.
Shall be provided. The height position of the upper recess 8 is referred to as height position A, and the height position of the lower recess 8 is referred to as height position B. A cargo ship or the like is usually provided with a crane used for loading cargo or the like. In this embodiment, this crane is used to raise and lower the middle deck 2 to a predetermined height position. For example, in FIG.
The middle deck 2b has a wire 30 suspended from the crane tip.
In this state, the middle deck 2 is lifted and lowered.

First, as shown in FIG. 1A, the middle deck 2 supported at the height position A in a state where the seat 9 and the oilless metal 11 are in contact with each other is slightly raised by a crane. The relative positional relationship between the middle deck 2 and the recess 8 at the height position A when slightly raised in this manner is shown in FIG.
The positional relationship is as shown in FIG. With this positional relationship, there is no obstacle in rotating the protruding arm member 4 until the arm member 4 enters the retracted state. Then, while maintaining this positional relationship, the arm member 4 is rotated from the protruding state to the retracted state.

Then, while the arm member 4 is kept in the retracted state, the middle deck 2 is moved to the height position B by a crane this time.
Up and down to a slightly higher position than

While the crane is moving up and down, the arm member 4 of the middle deck support device is in the retracted state. When the middle deck 2 moves to a position slightly higher than the height position B, the ascent / descent is temporarily stopped there. Height position B
The position slightly above is a position where the positional relationship between the middle deck 2 and the concave portion 8 at the height position B is, for example, as shown in FIG. 1B. In this position, there is no obstacle in rotating the arm member 4 from the retracted state to the projected state. Then, the arm member 4 is rotated so that the arm member 4 is in the protruding state at this position.

Further, while slightly lowering the middle deck 2 while maintaining this protruding state, the state shown in FIG.
That is, the oilless metal 1 attached to the arm member 4
1 and the receiving seat 9 of the recess 8 come into contact with each other, and the middle deck 2 is supported at the height position B.

Next, holding means for holding the arm member 4 in the protruding state and the retracted state will be described with reference to FIGS.

FIGS. 2 and 3 show an example of such a holding means. FIG. 2A is a view of the arm member 4 to which the weight 13 is added as viewed from the center axis direction of the shaft member 5, and FIG. 2B is a view of the arm member 4 as viewed from the weight 13 side. It is. Here, by positioning the center of gravity of the arm member 4 within a predetermined range, the arm member 4 is held in a protruding state or a stored state.
Here, the predetermined range refers to the side of the middle deck 2 with respect to the center axis when the arm member 4 is in the protruding state.
Is in the retracted state, the range is closer to the concave portion 8 than the central axis.

When the arm member 4 is in the protruding state, the portion closer to the middle deck 2 than the center axis is the range indicated by oblique lines in FIG. When the arm member 4 is in the retracted state, the portion closer to the concave portion 8 than the center axis is the range shown by the oblique lines in FIG. 3B.

To form the arm member 4 such that the center of gravity of the arm member 4 is located in such a range, for example, as shown in FIG.
The weight 13 may be added to a predetermined position of the arm member 4 formed symmetrically with respect to the axis, or a predetermined portion may be cut out.

2 and 3, the center of gravity of the arm member 4 is located at the point indicated by the cross mark in FIG.
This cross mark is within the range of the oblique line in FIG.
3 (b).

FIG. 3A shows a state in which the arm member 4 is held in a protruding state in the movable middle deck support device having the arm member 4 configured as shown in FIG. Here, a stopper 10 provided on the middle deck 2 supports the arm member 4 which is about to rotate clockwise by the added weight 13.

FIG. 3B shows a state in which the arm member 4 is held in the retracted state in the movable middle deck support device having the arm member 4 configured as shown in FIG. Here, the arm member 4 tries to rotate in the counterclockwise direction by the added weight 13, but the peripheral member 7 provided on the peripheral portion of the middle deck 2 supports this. Thereby, the arm member 4 is held in the stored state.

In order to release these holding states, it is necessary to externally apply a moment sufficient to lift the position of the center of gravity indicated by the mark x and move it to the opposite side of the center axis.

FIG. 8 shows a specific shape of the cross section of the shaft member 5.
Shows a non-circular shape by providing a protruding portion 5 a on a part of the circumference of the shaft member 5. As a specific shape of the bearing hole 27 of the bearing portion 26 that supports the shaft member 5, in FIG.
a, and side portions 27b rising vertically from both ends of the bottom portion 27a. A corner portion formed by the bottom portion 27a and the side portion 27b constitutes a locking portion 27c.

The locking portion 27c and the protruding portion 5a are arranged so that the locking portion 27c and the protruding portion 5a are engaged when the arm member 4 is in the protruding state or the retracted state. Then, in the engaged state, the state is maintained by the weight of the arm member 4. Thus, the arm member 4 is held in the protruding state or the retracted state. In order to release this holding state, it is necessary to apply a predetermined moment to the arm member 4 from outside.

Next, various devices for rotating the arm member 4 will be described with reference to FIGS.

FIG. 9 shows a first embodiment of the device for rotating the arm member. Here, a configuration is shown in which the arm member 4 is provided with a lever 16 for rotating the arm member 4 between the projected state and the stored state.

As described above, the arm member 4 is substantially balanced in weight around the central axis during rotation, and its center of gravity is located near the central axis during rotation. Therefore, a large force is not required to rotate the arm member 4. Therefore, as shown in FIG. 9, the arm member 4 can be rotated by attaching the lever 16 to the end of the shaft member 5 and manually rotating the lever 16. The lever 16 and its surroundings are shown in FIG.
Is enlarged. FIG. 9 shows a configuration in which two shaft members 5 are connected by a connection shaft 28 and two arm members 4 can be rotated by operating one lever 16. As described above, the arm member 4 is moved from the retracted state to the projected state without using a large-scale mechanism dedicated to rotating the arm member 4.
Alternatively, the state can be shifted from the protruded state to the stored state.

Note that the two middle decks 2a, 2a, 2a in FIG.
b are adjacent to each other in the hold 1, and the operator 50 in the figure is on the other side of the middle deck 2 a that has already been supported at a predetermined height position with the arm member 4 protruding. The arm member 4 of the middle deck 2 b is about to be rotated by the lever 16. FIG. 10 is a diagram for more clearly showing the relative height positional relationship between the two middle decks 2a, 2b. As shown in FIG.
In this embodiment, the lever 16 is removable. Therefore, even when the two middle decks 2a and 2b are close to each other, the relative height of the two middle decks 2a and 2b is within a range in which the arm member 4 of the middle deck 2b can be engaged with the concave portion 8. If the position is kept at a certain level or more, the operation of the lever 16 for rotating the shaft member 5 of one middle deck 2b does not prevent the other middle deck 2a from operating. When the space between two adjacent middle decks 2a and 2b is sufficiently large, the shaft member 5
A non-detachable lever may be provided at the end of the. Although the right end of the middle deck 2 b is shown in FIG. 10, a similar structure is adopted at the left end of the middle deck 2 b, and the middle deck 2 b is supported by four arm members 4. In such a case, the two left and right connection shafts 28 are connected by a link, and the operation of one lever 16 causes the four arm members 4 to be connected.
May be rotated.

As apparent from FIG. 9,
The operator 50 moves the middle deck 2 up and down by a crane or the like.
The arm member 4 can be rotated using the lever 16 while confirming the relative height positional relationship between the b and the recess 8. As described above, the operator 50 checks the height position of the middle deck 2b near the recess 8 and the arm member 4
Can be performed.
On the other hand, in the prior art as shown in FIG.
Apart from those who check the height position of the near the recess 108,
A person who performs a rotating operation of the arm member 104 is required. In the present invention, the operator 50 who confirms the height position of the middle deck 2b near the concave portion 8 can perform the rotation operation of the arm member 4 only when the center of gravity of the arm member 4 is rotated. Because it is located near the central axis, a large driving force is not required for the turning operation, and therefore, the arm member 4 can be sufficiently turned by the manual operation of the lever 16.

FIG. 11 shows a second embodiment of the device for rotating the arm member 4. Here, a configuration in which a lever 17 is provided on the arm member 4 and a rope 18 is provided on the lever 17 is shown. This rope 18 is for remotely operating the lever 17. Here, ropes 18 are hung from both ends of a lever 17 provided at one end of the shaft member 5, and a handle 19 is provided at the lower end of each rope 18. The operator 50 is at the bottom of the hold 1 and operates the handle 19 to move the arm member 4.
Is performed.

In FIG. 11, the rope 1 is
8 hanging, but handle 1 placed on upper deck etc.
9, the rope 18 is hung, the lower end of the rope 18 is connected to the end of the lever 17 attached to the end of the shaft member 5, and the operator 50 uses the handle 19 to hold the rope 1.
The rotation operation of the arm member 4 may be performed by operating the lever 17 from above.

FIG. 12 shows a third embodiment of the device for rotating the arm member.

Here, two drums 31 a and 31 b are attached to the shaft member 5. These drums 31a and 31b rotate integrally with the arm member 4. A rope 32 is attached to both drums 31a and 31b.
a and 32b are wound, but the winding directions of the rope 32a and the rope 32b are different. That is,
A rope 32a is wound around the drum 31a on the left side in the drawing so as to be pulled out from the upper part of the drum 31a to the right side in the drawing (hereinafter, referred to as upper winding), and the drum 31b on the right side in the drawing is a drum. The rope 32b is wound so as to be pulled out from the lower part of the base 31b to the right side in the drawing (hereinafter, referred to as lower winding). Drum 31a
The rope 32a wound up from above is connected to the hook 33a hanging down from above, while the rope 32b wound down from around the drum 31b is connected to the hook 33b hanging down from above. The hooks 33a and 33b are connected to the rope 34
The ropes 34a and 34b are connected to winches (not shown) via a and 34b, respectively, and can be individually pulled by operating the winch. As the winch, for example, a dedicated small winch provided on a deck crane for suspending the middle deck 2 can be used. In this case, it is best to use an auto tension winch. In addition, instead of using a dedicated small winch, for example, a supplementary hoist usually attached to a large crane may be used in the auto tension mode. Further, the ropes 34a and 34b may be pulled by a manual operation of the operator 50 on the upper deck or the like without using a winch or an auxiliary winding.
In FIG. 12, by pulling the rope 34a, the arm member 4 is rotated clockwise as viewed from the left side in the figure, and by pulling the rope 34b, the arm member 4 is rotated counterclockwise. According to such a method, the operator 50 can perform the rotation operation of the arm member 4 without entering the hold 1.

Next, the urging means for urging the arm member 4 so that it always projects will be described with reference to FIGS.

FIG. 13 shows a first embodiment of the urging means. FIG. 13A shows a case where the arm member 4 is in a state close to the stored state. FIG. 13B shows a case where the arm member 4 is in a protruding state.

The biasing means can be constituted, for example, by balancing the center of gravity of the arm member 4 such that the center of gravity of the arm member 4 is always located closer to the middle deck 2 than the center axis even in the protruding state and the retracted state. In order to form the balance of the center of gravity in this way, for example, a weight may be added to a predetermined position of the arm member 4 formed to be axially symmetric, or a notch 35 is provided at a predetermined portion of the arm member 4. You may do so. FIG. 13 shows the latter.

Since the notch 35 is provided, the center of gravity of the arm member 4 in FIG. 13 is located at the point indicated by the cross mark in the figure. In the state shown in FIG. 13A, the position of the mark x, that is, the position of the center of gravity, is larger than the center axis of the arm
In the range on the right side (the range indicated by oblique lines). FIG.
In the state of (b), the position of the mark “x” is larger than the center axis by
In the range on the right side (the range indicated by oblique lines). This allows
A moment always acts on the arm member 4 in the direction from the retracted state to the projected state, that is,
It will be urged to be in a protruding state. FIG.
As shown in (a), the arm member 4 keeps the state in which the tip of the arm member 4 is in contact with the hold wall surface 3 at a height position not facing the recess 8. At this time, the leading end of the arm member 4 remains in contact with the hold wall surface 3 and does not enter the completely retracted state because the arm member 4 is biased as described above. 13A, when the middle deck 2 in the state of FIG. 13A is moved to the height position where the arm member 4 faces the concave portion 8, the arm member 4 naturally projects. , And finally comes to a state as shown in FIG.

FIGS. 14 to 16 show a second embodiment of the urging means. FIG. 14 is a perspective view showing the second embodiment, FIG. 15 is a view for explaining the operation of the second embodiment, and FIG. 16 is a sectional view of the drum 36.

Here, the biasing means is constituted by an elastic member. One end of the elastic member is fixed to the middle deck 2 side, and the other end is fixed to the arm member 4 side. Then, the arm member 4 is urged to always be in a protruding state by the elastic force of the elastic member.

In FIG. 14, the drum 36 is provided rotatably with respect to the shaft member 5. A rope 38 is wound around the outer peripheral surface of the drum 36. The rope 38 is pulled out from the upper part of the drum 36 to the right side in the drawing, and a handle 39 is provided at an end thereof. A hook piece 40 is fixed to a predetermined position of the rope 38. The support 37 is fixed to the middle deck 2. As shown in FIG. 16, a mainspring 41 is provided inside the drum 36. One end of the mainspring 41 is fixed to the inner peripheral surface of the drum 36, and the other end is fixed to the surface of the shaft member 5.

Now, with the arm member 4 in the retracted state, the relative height position of the middle deck 2 with respect to the concave portion 8 is
Assume that it is as shown in FIG. Here, when the operator 50 pulls the handle 39 rightward in FIG. 14, the arm member 4 rotates to the protruding side, and the distal end portion thereof comes into contact with the hold wall surface 3 as shown in FIG. When the operator 50 further pulls the handle 39, the arm member 4 is biased by the mainspring 41 in the drum 36 in the direction from the retracted state to the projected state. Then, when the hook piece 40 is hooked on the support member 37, this biased state is maintained.

In order to urge the arm member 4 to be always in the protruding state, the position of the center of gravity of the arm member 4 is set within a predetermined range as shown in FIG.
In addition to using the mainspring 41 as shown in FIG. 7, various configurations can be adopted. For example,
A spring (such as a torsion spring) other than the mainspring can also be used.

When the arm member 4 is urged by the urging means as described above, the middle deck 2 supported at a certain height position is moved up and down to be supported at another height position. In addition, the following operation method can be adopted, which is convenient. This operation method will be described with reference to FIGS.

FIG. 17 shows the arrangement of the recesses 8 provided vertically in three stages on the hold wall surface 3. What is indicated by the two-dot chain line at the height of C is the side surface shape of the middle deck 2 supported at the height of C.

FIG. 18 (a) shows the process of moving the middle deck 2 when moving the middle deck 2 supported at the E position to the D or C height position with arrows. Things.

FIG. 18 (b) shows the process of moving the middle deck 2 when moving the middle deck 2 supported at the height of C to the height of D or E by arrows. Things.

First, an operation procedure when the middle deck 2 supported at the height position E is shifted to the height position D and supported will be described. In this case, first, the middle deck 2 supported at the height position of E is lifted directly by a crane or the like. Then, while the arm member 4 keeps the protruding state, the tip end thereof separates from the bottom of the recess 8 at the height E and hits the ceiling of the recess 8. When the middle deck 2 is further raised, the arm member 4 starts rotating from the protruding state to the retracted state. Further raise the middle deck 2, and
When the arm member 4 reaches the intermediate height position between
Is kept in a state close to the retracted state, although its tip remains in contact with the hold wall surface 3. At this time, the leading end of the arm member 4 remains in contact with the hold wall surface 3 and does not enter the completely retracted state because the arm member 4 is biased as described above. Then, when the middle deck 2 is further raised to a position slightly higher than the height position of D, the tip of the arm member 4 becomes the concave portion 8 of D.
It starts to rotate in the direction of the protruding state in such a manner as to get inside. The pivoting is performed because the arm member 4 is biased as described above. When the arm member 4 is in a completely protruding state or a state close to this,
This time, the middle deck 2 is lowered. Then, the arm member 4
Is in a completely protruding state, and its tip end abuts against the bottom of the concave portion 8 of D, whereby the middle deck 2 is supported at the height of D.

In the same manner as the operation procedure for shifting the middle deck 2 supported at the height position E to the height position D and supporting it, as described above, the middle deck 2 is supported at the height position D. The middle deck 2 that has been moved to the height position C can be supported.

Next, an operation procedure in the case where the middle deck 2 supported at the height position C is shifted to the height position D and supported is described. In this case, first, the middle deck 2 supported at the height position of C is slightly raised by a crane or the like. Then, first, with the arm member 4 kept in the protruding state, the distal end thereof separates from the bottom of the concave portion 8 at the height of C and hits the ceiling of the concave portion 8. When the middle deck 2 is further raised, the arm member 4 starts rotating from the protruding state to the retracted state. When the middle deck 2 is further raised,
The arm member 4 is kept in a state close to the retracted state, although its tip end is kept in contact with the hold wall surface 3.
At this time, the distal end of the arm member 4 remains in contact with the hold wall surface 3 as described above. Next, while maintaining this height position, the horizontal coordinate position of the concave portion 8 and the arm member 4 are set.
The middle deck 2 is moved in the horizontal direction until the horizontal coordinate positions no longer match. Here, the horizontal direction is the horizontal direction in FIG. Then, the middle deck 2 is lowered to a height intermediate between the height position of C and the height position of D. In the course of this lowering, the arm member 4 once passes through the height position of C, but since the horizontal coordinate position of the concave portion 8 and the horizontal coordinate position of the arm member 4 do not match, the arm member 4 It does not rotate in such a manner that its tip enters the recess 8 of C. Next, the horizontal coordinate position of the concave portion 8 matches the horizontal coordinate position of the arm member 4 while maintaining this height position (a height position intermediate between the height position of C and the height position of D). Until
The middle deck 2 is moved in the horizontal direction. Next, when the middle deck 2 is lowered to a position slightly higher than the height position of D,
The arm member 4 starts rotating in the protruding state in such a manner that its tip end enters the concave portion 8 of D. When the middle deck 2 is further lowered, the arm member 4 is in a completely protruding state, and its tip end abuts against the bottom of the concave portion 8 of D, whereby the middle deck 2 is supported at the height position of D. You.

The same applies to the case where the middle deck 2 supported at the height position C is shifted to the height position E and supported.
First, the middle deck 2 supported at the height position of C is slightly raised by a crane or the like. Then, first, while the arm member 4 keeps the protruding state, the distal end thereof separates from the bottom of the concave portion 8 at the height C and hits the ceiling of the concave portion 8. When the middle deck 2 is further raised, the arm member 4 starts rotating from the protruding state to the retracted state. When the middle deck 2 is further raised, the arm member 4 is maintained in a state close to the retracted state, although the tip end thereof is kept in contact with the hold wall surface 3. Next, while maintaining this height position, the middle deck 2 is moved in the horizontal direction until the horizontal coordinate position of the concave portion 8 and the horizontal coordinate position of the arm member 4 no longer match. Then, the middle deck 2 is lowered to a height intermediate between the height positions D and E. In the course of this lowering, the arm member 4 once passes through the height position of C and the height position of D, but the horizontal coordinate position of the concave portion 8 does not match the horizontal coordinate position of the arm member 4. Therefore, the arm member 4 does not rotate in such a manner that the tip of the arm member 4 enters the concave portion 8 of C or D. next,
While maintaining the intermediate height position between the height position of D and the height position of E, the middle deck 2 is moved until the horizontal coordinate position of the concave portion 8 matches the horizontal coordinate position of the arm member 4. When the arm member 4 is moved in the horizontal direction and the middle deck 2 is lowered, the arm member 4 starts rotating in the protruding state in such a manner that its tip end enters the concave portion 8 of E. When the middle deck 2 is further lowered, the arm member 4 is brought into a completely protruding state, and its tip end is brought into contact with the bottom of the concave portion 8 of E, whereby the middle deck 2 is supported at the height position of E. Is done.

As described above, when the urging force is applied to the arm member 4, the height position of the middle deck 2 can be changed without rotating the arm member 4.

When such a middle deck 2 is taken out of the hold 1, the middle deck 2 is higher than the hatch combing top 42 of the hold 1 with the biasing force applied to the arm member 4 as described above. When the arm member 4 is raised to the position, the arm member 4 is rotated by the urging so as to be in a protruding state. The middle deck 2 from which the arm member 4 has once protruded.
To be lowered into the hold 1 again, the arm member 4
Is caught on the hatch combing top 42,
It cannot be lowered into the hold 1. Therefore, hold 1
Before lowering the arm member 4, it is necessary to return the arm member 4 to a state close to the original storage state, but a certain amount of force is required to rotate the arm member 4 toward the storage side against the biasing direction. Therefore, labor is required. FIG. 19 shows a technique for eliminating this labor. Here, the U-shaped member 43 provided on the rear end of the arm member 4 is connected to the stopper pin 4 provided on the middle deck 2.
4 shows a device that hooks the arm member 4 to lock the arm member 4 in a state close to the retracted state. The stopper pin 44 is detachable from the middle deck 2. The method of using this device is described below.

When the middle deck 2 is to be raised to a position higher than the hatch combing top 42 of the hold, the stopper pins 44 are attached to the middle deck 2 in advance. FIG. 19A shows this state.

After that, even if the middle deck 2 is raised to a position higher than the hatch combing top 42, the U-shaped member 43 is caught by the stopper pin 44, and the arm member 4 remains locked in a state close to the retracted state. . FIG. 19B shows this state. Even if the middle deck 2 is lowered again from the state of FIG. 19B, the tip of the arm member 4 does not get caught on the hatch combing top 42, and the middle deck 2 can be lowered into the hold 1. Then, when the inner deck 2 descends into the hold 1 and becomes the state shown in FIG. 19A again, the stopper pin 44 is removed from the inner deck 2.

As described above, by providing the locking means for locking the arm member 4 urged in the direction from the retracted state to the protruding state at a predetermined position, the middle deck 2 is held in the hold 1. Labor saving can be achieved in the work of getting out of the vehicle from the outside or entering the hold 1.

When lowering the middle deck 2 raised to a position higher than the hatch combing top 42 into the hold 1, the tip of the arm member 4 must be inserted smoothly into the hold 1 as shown in FIG. It is effective to provide a metal member 45 having a semicircular cross section at the edge portion of the hatch combing top 42 as shown in b).
