A luggage securing system according to an embodiment of the present invention will be described with reference to a securing system ST of an example. The lash holding system ST includes a container 1 for transportation, lashing rails 3a to 3d, and a lashing belt 5. Hereinafter, the lashing rails 3a to 3d are simply referred to as rails 3a to 3d.
First, with reference to FIG.1 and FIG.2, schematic structure of the container 1 is demonstrated. FIG. 1 is a perspective view showing a transport vehicle 51 on which a container 1 is mounted. The front, rear, left, and right directions define the forward direction of the transport vehicle 51 as the front. Front and rear, left and right and top and bottom correspond to width, depth and height, respectively. FIG. 2 is a schematic cross-sectional view of the container 1 at the position S2-S2 in FIG.

The transport vehicle 51 includes a vehicle body 52, a container 1 installed in a loading platform portion behind the vehicle body 52, and a refrigeration apparatus that maintains the internal temperature of the container 1 at a desired temperature. The refrigeration apparatus includes a condenser unit 53, a plurality of evaporator units (not shown), a compressor, and the like.
The container 1 includes a front wall 1a, a left side wall 1b, a right side wall 1c, a top wall 1d, and a floor wall 1e having heat insulating properties, and is formed in a rectangular parallelepiped box shape.
The container 1 includes an opening / closing door 1fa and an opening / closing door 1fb (illustrated by a two-dot chain line) that are attached to the rear end portions of the left side wall 1b and the right side wall 1c and have heat insulation properties as shown by an arrow Da.
As a result, the container 1 is formed in a box shape whose rear surface can be opened and closed by the opening and closing doors 1fa and 1fb. With the opening and closing doors 1fa and 1fb being closed, the cargo compartment M can be moved by heat from the outside. Is sufficiently blocked. Therefore, the front wall 1a becomes a back wall when viewed from the opening side.
In the container 1, a partition wall 2 extending in the front / rear / up / down direction is manually detachable by a well-known structure at the center in the width direction of the cargo compartment M. In FIG.1 and FIG.2, the state to which the partition wall 2 was attached is shown.

The loading chamber M is divided into two loading chambers, a left loading chamber M1 and a right loading chamber M2, which are sufficiently blocked from each other by attaching the partition wall 2.
The evaporator unit (not shown) is suspended from the top wall 1b inside each of the cargo compartments M1, M2. The cargo compartment M1 and the cargo compartment M2 can be maintained independently of each other in a state in which the doors 1fa and 1fb are closed by the capacitor unit 53, each evaporator unit, a compressor, and the like. For example, the cargo compartment M1 can be used as a freezer compartment, and the cargo compartment M2 can be used as a refrigerator compartment having a temperature higher than that of the cargo compartment M1.
The internal law of the container 1 is determined within a limited range to some extent because it is mounted on a transport vehicle. In the internal method, the width W is about 2300 mm, the height H is about 2440 mm, and the depth L is about 9500 mm. The width W1 of the luggage compartment M1 and the width W2 of the luggage compartment M2 are each about 1100 mm. The partition wall 2 is formed with a width (thickness) of 100 mm, for example.

In the cargo compartment M1, the container 1 is installed in the lower part of the inner surface 1b1 of the left side wall 1b so as to extend in the direction (front-rear direction) in which the rail 3a is separated from and in contact with the front wall 1a. Moreover, the rail 3b is extended and installed in the direction (front-back direction) which is separated from the front wall 1a in the position which approached the partition wall 2 side of the inner surface 1d1 of the top wall 1d.
On the other hand, in the luggage compartment M2, a rail 3c extends in the front-rear direction at the lower portion of the inner surface 1c1 of the right side wall 1c. Moreover, the rail 3d is extended and installed in the position close | similar to the partition wall 2 side of the inner surface 1d1 of the top wall 1d. The rails 3a and 3c are installed in parallel with the floor surface 1e1 of the floor wall 1e, for example. The rail 3b and the rail 3d are installed in parallel with, for example, the inner surface 1b1 of the left side wall 1b and the inner surface 1c1 of the right side wall 1c.

The rails 3a to 3d are rail-shaped members in which a plurality of rectangular engagement holes are arranged in parallel at a predetermined pitch, and commercially available products can be used. An engagement fitting attached to the end portion of the lashing belt can be engaged with each engagement hole. Further, the length of the rails 3a to 3d is set to a length that is substantially close to the depth L of the luggage compartment M. For example, it is 9000 mm.
A lashing belt 5 can be attached to the rails 3a to 3d. The tying belt 5 includes a connecting belt 6 and a tightening belt 7, and the connecting belt 6 and the tightening belt 7 are connected by an attaching / detaching portion 67 to form a single tying belt 5 in use.

FIG. 3 is a plan view showing the connecting belt 6. The connecting belt 6 includes a belt base portion 6a, an engagement fitting 6b attached to one end side of the belt base portion 6a, and a connecting member 6c attached to the other end side. The belt base 6a has a length La of, for example, 250 mm. The engagement metal fitting 6b is a metal fitting that can be engaged with and disengaged from the rectangular engagement hole of the rail 3b, and the connecting member 6c is an annular member called, for example, a delta ring.
FIG. 4 is a plan view showing the tightening belt 7. The fastening belt 7 has a fixed side belt portion 7a and an adjustment side belt portion 7c connected to one end side of the fixed side belt portion 7a via a buckle 7b. An engagement fitting 7d is attached to the other end side of the fixed side belt portion 7a. A connecting member 7e is attached to the end of the adjustment side belt portion 7c.
The engagement fitting 7d is a fitting that can be engaged with and disengaged from the engagement hole of the rail 3a, and the connecting member 7e is a hook member called a narrow hook, for example, and can be engaged with and disengaged from the connecting member 6c. . That is, the fastening belt 7 is provided with an attaching / detaching portion 67 including a connecting member 6c and an engagement fitting 7d at an intermediate portion thereof, and can be divided.

  The buckle 7b is, for example, a ratchet buckle, and includes a tightening portion (not shown) that tightens the adjustment side belt portion 7c by a ratchet mechanism. That is, the amount of tightening (tightening length) can be adjusted by tightening between the buckle 7b of the adjustment side belt portion 7c and the connecting member 7e by the buckle 7b. For example, the length of the fixed side belt portion 7a is constant at 0.5 m, and the length between the buckle 7b and the connecting member 7e of the adjustment side belt portion 7c can be adjusted to be short by tightening with the buckle 7b (the longest length). For example 4m).

  The container 1 can hold and hold a load using the lashing belt 5 (hereinafter also referred to as lash holding) in the luggage compartments M1 and M2. In this lash-holding, the lashing belt 5 is pressed against the inner surface of the container 1 by holding and tightening the lashing belt 5 without wrapping it around the luggage. Since the securing method is common to the cargo compartment M1 and the cargo compartment M2, a method of fixing the luggage N1, N2 in the cargo compartment M1 will be described with reference to FIGS.

The luggage N1, N2 is, for example, a rectangular parallelepiped (including a cube), and has a height that is lower than the inner height of the luggage compartment M1 so that a space is formed between the top surfaces N1e, N2e and the inner surface 1d1 of the top wall 1d when loaded. Is set.
When the inner height H of the cargo compartment M1 is 2440 mm as described above, the maximum height of the loads N1 and N2 is about 2000 mm in the loaded state.
In the following description, the height Hn1 of the luggage N1, N2 is 2000 mm, and the luggage N1 has a width Wn1 shorter than the distance W1a from the inner surface 1b1 of the left side wall 1b to the rail 3b attached to the inner surface 1d1 of the top wall 1d. Each securing procedure will be described assuming that the baggage N2 is a narrow baggage, the baggage N2 is a thick baggage whose width Wn2 (see FIG. 8) is longer than the distance W1a.

(In the case of luggage N1) FIGS. 5 to 7 show a state in which a narrow luggage N1 is placed in the luggage compartment M1 in a posture parallel to the left side wall 1b.
First, the operator attaches the connecting belt 6 by engaging the engagement fitting 6b with the rail 3b of the top wall 1d. As a result, the connecting belt 6 is in a state of hanging from the rail 3b as shown by a two-dot chain line in FIG. The lower end of the connecting belt 6 is located above the top surface N1e of the luggage N1. A part of the rail 3b where the engagement fitting 6b is attached is referred to as an attachment part T1. As shown in FIG. 6, the position P1 in the front-rear direction of the attachment site T1 is more forward than the position P2 in the front-rear direction of the rear surface N1a of the load N1 when the load N1 is brought into contact with the inner surface 1a1 of the front wall 1a. And

Next, the worker extends the fastening belt 7 sufficiently long and engages the engagement fitting 7d with the engagement hole of the rail 3a provided on the left side wall 1b. As a result, the fastening belt 7 is attached to the rail 3a. A part where the engagement fitting 7d is attached in the rail 3a is referred to as an attachment part T2.
The position P3 in the front-rear direction of the attachment site T2 is located behind the position P2 in the front-rear direction of the rear surface N1a when the load N1 is brought into contact with the inner surface 1a1 of the front wall 1a (FIG. 6).

Next, the operator connects the connecting member 7 e of the fastening belt 7 and the connecting member 6 c of the connecting belt 6 to form one lashing belt 5. And the adjustment side belt part 7c is tightened with the buckle 7b. At that time, the adjustment side belt portion 7c is tightened in a state where it is hung on the upper and lower ridgeline N1b which is the boundary ridgeline between the rear surface N1a and the right side surface N1c of the load N1. The vertical ridgeline N1b is the ridgeline farthest from both the left side wall 1b and the front wall 1a.
At this time, as shown in FIG. 5, since the position of the attachment portion T1 in the left-right direction is on the right side of the position of the right side surface N1c of the luggage N1, the fastening belt 7 is vertically ridged with respect to the luggage N1. It can be multiplied only by N1b.

  Next, the operator tightens the adjustment side belt portion 7c with an appropriate tightening force by the buckle 7b. This state is referred to as a secured holding state of the load N1, and a portion of the vertical ridge line N1b where the adjustment side belt portion 7c is applied is defined as a belt hooking portion K1.

In the rear view of FIG. 5, with the luggage N1 being held in a secured state, the belt is hooked on a virtual line segment LN1 that connects the attachment portion T1 of the top wall 1d of the lashing belt 5 and the attachment portion T2 of the left side wall 1b. The part K1 is in the region on the opposite side (right side) of the left side wall 1b.
Further, in the top view of FIG. 6, with respect to the virtual line segment LN2 that connects the attachment site T1 on the top wall 1d of the lashing belt 5 and the attachment site T2 on the left side wall 1b in the state of holding the luggage N1 in a lashing state. The belt hooking portion K1 is in a region on the opposite side (rear side) of the front wall 1a.
Thereby, the load N1 is pressed against both the inner surface 1b1 of the left side wall 1b and the inner surface 1a1 of the front wall 1a by tightening the lashing belt 5 in the lashing holding state. That is, the luggage N1 is pressed against the two wall surfaces and held.

(In the case of luggage N2) FIGS. 8 to 10 show a state in which a thick luggage N2 is placed in the luggage compartment M1 in a posture parallel to the left side wall 1b.
First, as in the case of the luggage N1, the worker attaches the connecting belt 6 by engaging the engagement fitting 6b with the rail 3b of the top wall 1d. Thus, the lower end of the connecting belt 6 is above the top surface of the luggage N2.
The position P1 in the front-rear direction of the attachment site T1 is forward of the position P2 in the front-rear direction of the rear surface N2a of the load N2 when the load N2 is brought into contact with the inner surface 1a1 of the front wall 1a.

  Next, the operator extends the fastening belt 7 sufficiently long and engages the engagement fitting 7d with the engagement hole of the rail 3a provided on the left side wall 1b. As a result, the fastening belt 7 is attached to the rail 3a at the attachment portion T2. The position P3 in the front-rear direction of the attachment site T2 is located behind the position P2 in the front-rear direction of the rear surface N2a of the luggage N2 (FIG. 9).

Next, the operator connects the connecting member 7 e of the fastening belt 7 and the connecting member 6 c of the connecting belt 6 to form one lashing belt 5. And the adjustment side belt part 7c is tightened with the buckle 7b. At that time, the adjustment side belt portion 7c includes a vertical ridge line N2b which is a boundary ridge line between the rear surface N2a and the right side surface N2d of the luggage N2, and a front and rear ridge line N2c which is a boundary ridge line between the right side surface N2d and the top surface N2e of the luggage N2. , And tighten it in the state A portion of the adjustment side belt portion 7c between the upper and lower ridge lines N2b and the front and rear ridge lines N2c comes into contact with the right side surface N2d of the load N2 on the surface. The vertical ridgeline N2b is the ridgeline farthest from both the left side wall 1b and the front wall 1a.
At this time, as shown in FIG. 8, since the position of the attachment portion T1 in the left-right direction is on the left side of the position of the right side surface N2d of the luggage N2, the tightening belt 7 is connected to the luggage N2 in the front-rear ridgeline. N2c, right side surface N2d, and vertical ridgeline N2b can be applied and hung.

  Next, the operator tightens the adjustment side belt portion 7c with an appropriate tightening force by the buckle 7b. This state is referred to as the holding state of the load N2, and the portion of the upper and lower ridgeline N2b where the adjustment side belt portion 7c is applied is defined as a belt application portion K2, and the adjustment side belt portion 7c of the front and rear ridgeline N2c is applied. Let the site | part currently set | formed be the belt hooking site | part K3.

In the rear view of FIG. 8, with the luggage N2 held in a lashed state, a belt is applied to a virtual line segment LN3 that connects the attachment site T1 on the top wall 1d of the lashing belt 5 and the attachment site T2 on the left side wall 1b. The part K2 and the belt hooking part K3 are in the region on the opposite side (right side) of the left side wall 1b. In addition, in the top view of FIG. 9, with respect to the imaginary line segment LN4 that connects the attachment site T1 on the top wall 1d of the lashing belt 5 and the attachment site T2 on the left side wall 1b in the state where the luggage N2 is secured. The belt hooking portion K2 and the belt hooking portion K3 are in a region on the opposite side (rear side) of the front wall 1a.
Thereby, the load N2 is pressed against both the inner surface 1b1 of the left side wall 1b and the inner surface 1a1 of the front wall 1a by tightening the lashing belt 5 in the lashing holding state. That is, the luggage N2 is pressed against the two wall surfaces and held.

In this way, the container 1 can hold the loads N1 and N2 against the two wall surfaces orthogonally connected to the cargo compartment M1 using the lashing belt 5. As a result, the loads N1 and N2 can be more stably held. The same applies to the luggage compartment M2.
Moreover, it is not necessary to prepare a mounting table on which a load is placed and to provide a guide structure between the mounting table and the side wall. Therefore, the stable holding of the loads N1 and N2 is possible with a simple container structure.

  Even when the luggage compartment M is used in one room without the partition wall 2 attached, the luggage N1 and N2 are secured by the lashing belt 5 spanned between one of the rails 3a and 3c and one of the rails 3b and 3d. Can be secured and secured. An example is shown in FIG.

  FIG. 11 shows a state in which luggage N3 and N4 wider than the luggage N2 are secured and held in one luggage compartment M using the securing belt 5 as an example of a securing method. The luggage N4 is wider than the luggage N3, and the vertical ridge line N3a at the right rear end of the luggage N3 is indicated by a one-dot chain line. The left-right position of the top / bottom ridge line N3a of the luggage N3 is between the rail 3b and the rail 3d, and the left-right position of the top / bottom ridge line N4a at the right rear end of the luggage N4 is located to the right of the rail 3d. .

For the load N3, a connecting belt 6 indicated by a two-dot chain line is attached to the rail 3d in front of the rear surface N3c of the load N3. Then, the engagement fitting 7d in the fastening belt 7 indicated by the two-dot chain line is attached to the rear of the rail 3a from the rear surface N3c, and the fastening belt 7 is connected to the connecting belt 6 so that one tie is secured. The belt 5 is used. Thereafter, the adjustment side belt portion 7c is fastened by the buckle 7b in a state where the adjustment side belt portion 7c is applied to the vertical ridge line N3a at one place of the belt hooking portion K5. As a result, the load N3 is secured. The method for securing the load N3 is the same as the method for securing the load N1, except that the width of the load is different. That is, the luggage N3 is pressed against and held by the two wall surfaces of the front wall 1a and the left side wall 1b.
For the load N4, the connecting belt 6 indicated by a solid line is attached to the rail 3d in front of the rear surface N4c of the load N4. Then, the engagement fitting 7d in the fastening belt 7 indicated by the solid line is attached to the rear side of the rear surface N4c with respect to the rail 3a, the fastening belt 7 is connected to the connecting belt 6, and one lashing belt and To do. Thereafter, the adjustment side belt portion 7c is fastened by the buckle 7b in a state where the adjustment side belt portion 7c is applied to the belt hooking portion K6 in the right rear upper and lower ridgeline N4a and the belt hooking portion K7 in the upper right front and rear ridgeline N4b. As a result, the load N4 is secured. The method for securing the load N4 is the same as the method for securing the load N2, except that the width of the load is different. That is, the luggage N4 is pressed against and held by the two wall surfaces of the front wall 1a and the left wall 1b.
In fixing the luggage N3 and N4, the rail 3b may be used instead of the rail 3d for the rail of the top wall 1d.

When the loads N1 to N4 are low, the position where the connecting belt 6 is attached to the rail 3b (3d) of the top wall 1d may be appropriately shifted forward. FIG. 12 is a partial right side view for explaining this, and shows an example of the baggage N1 and the baggage N1A having a height lower than that of the baggage N1.
As shown in FIG. 12, the attachment position of the connecting belt 6 is set to the position of the attachment part T1A in front of the attachment part T1 when the luggage N1 is fixed, so that the spanning position of the lashing belt 5 is set. Can be lowered.
As a result, even with the baggage N1A having a height of n, the adjustment side belt portion 7c is applied to the belt hooking position K1a of the right rear upper and lower ridgeline N1Aa and tightened to tighten the baggage N1A as two wall surfaces. It is possible to press and hold against 1a and the left side wall 1b and stably hold it. The same applies to the holding of the baggage N2A, which is shorter than the baggage N2.

  The rail 3a and the rail 3c attached to the inner surface 1b1 of the left side wall 1b and the inner surface 1c1 of the right side wall 1c protrude from the inner surface 1b1 and the inner surface 1c1, respectively. In this case, strictly speaking, the loads N1 to N4 are pressed against the inner surface 1b1 or the inner surface 1c1 with respect to the rails 3a and 3c. However, the protruding amount of the rails 3a and 3c is negligible in actual lash holding work. Therefore, it can be considered that the loads N1 to N4 are substantially pressed against the inner surface 1b1 of the left side wall 1b and the inner surface 1c1 of the right side wall 1c. Of course, the rails 3a and 3c may be provided so as not to protrude from the inner surfaces 1b1 and 1c1.

With the partition wall 2 attached, if the left and right attachment positions of the rails 3a and 3c are too close to the left side wall 1b and the right side wall 1c, respectively, the tying belt 5 is applied when the load to be secured is wide. Is easy to come off.
Therefore, it is preferable that the left and right mounting positions of the rails 3a and 3c with respect to the inner surface 1d1 of the top wall 1d are closer to the partition wall 2 than the centers of the width W1 of the cargo compartment M1 and the width W2 of the cargo compartment M2. When the distance from the partition wall 2 of the rails 3a and 3c is a distance W3b and a distance W3d, respectively, as shown in FIG.
It is preferable that the distance W3b ≦ (width W1) / 2 and the distance W3d ≦ (width W2) / 2.
It is more preferable that the distance W3b ≦ (width W1) / 4 and the distance W3d ≦ (width W2) / 4.
Moreover, it is preferable that the height H3 from the floor surface 1e1 of the rails 3a and 3c of the left side wall 1b and the right side wall 1c shown in FIG. More preferably, it is about 1/4 or less.

  In the securing operation, the height Hk from the floor surface 1e1 of the belt hooking portion K1 with respect to the load N1 shown in FIG. 5 is the upper side 2 of the height Hn1 of the load N1 from the viewpoint of effectively preventing the fall. The range is preferably within the range of / 3, and most preferably about 1/2. The same applies to the packages N2 to N4, N1A, and N2A.

When the lashing belt 5 is attached to the container 1 in the lashing holding operation, the engagement fitting 7d of the tightening belt 7 is engaged with the rail 3a at a position behind the rear surfaces N1a and N2a of the loads N1 and N2. Further, the connecting member 7e is previously attached to the rail 3b of the top wall 1d and engaged with the connecting member 6c of the connecting belt 6 that hangs above the top surfaces N1e and N2e. Thus, the lashing belt 5 may be unified. Accordingly, the engaging portion can be visually recognized without interfering with or hiding the load, and the attaching operation is easy.
Further, the position where the top wall 1d is attached to the rail 3b can be moved back and forth in accordance with the height of the loads N1 and N2, so that the contact position on the loads N1 and N2 can be moved up and down.
Thereby, the lashing belt 5 can be applied to the loads N1 and N2 at the optimum position according to the height thereof. Therefore, it is highly versatile and can hold a highly stable lash.

The securing of the container 1 and the loads N1, N2, and N1A is not limited to the contents of the embodiments, and may be modified without departing from the gist of the present invention.
The transport vehicle 51 may be a so-called dry carton that does not include a refrigeration apparatus.
The container 1 is not limited to the one mounted on the transport vehicle 51. It may be transported by being mounted on a moving body such as a railroad, a ship, and an aircraft. The container 1 may not include a pair of opposing side walls (the left side wall and the right side wall in the embodiment). Specifically, it has a floor wall on which a load is placed, a first side wall, a top wall, and a second side wall (back wall) that is orthogonally connected to the first side wall. The rail should just be attached to each with a wall.
