DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a partition wall for partitioning a luggage compartment of a freezer or refrigerated car into at least two or more parts at any position in the front-rear direction.

[0002]

2. Description of the Related Art Conventionally, a luggage compartment of a freezer or refrigerated car is divided at an arbitrary position in the front-rear direction by using an intermediate partition wall, and the luggage compartment is partitioned according to the use like a freezer compartment, a refrigeration compartment, or a room temperature compartment. It can also determine the position of the partition according to the amount of load.By installing such a partition wall, the luggage compartment can be used efficiently, the transportation efficiency can be increased and the refrigerated or refrigerated vehicle can be economically used. Operation is being performed.

[0003] This kind of partition wall has a heat insulating property for blocking heat flow through the wall, a robust property that does not easily break even when it hits a load, a handleability that can be detached at any position in the longitudinal direction of the load compartment, and a ceiling of the load compartment. It is also required to have a sealing property that can follow irregularities on both sides.

[0004]

However, at present, there is no partition wall that satisfies all of the above-mentioned characteristics. For example, in order to make the heat insulation excellent and to reduce the weight to improve the handling,
One that forms a partition wall with urethane foam has been proposed (see Japanese Utility Model Laid-Open No. 5-64142). However, urethane foam has low strength, and is fragile, for example, when it collapses, it is easily damaged, and it is difficult to attach and fix the handle for opening and closing, so it is necessary to increase the thickness. There is a problem with sex. In order to improve the ease of handling, a curtain type has been proposed (see Japanese Patent Application Laid-Open No. Hei 9-207648). is there.

[0005] In order to increase the strength of
For example, a partition wall filled with urethane foam between aluminum molds is also used. However, since a metal mold is used, it is heavy and cannot be attached or detached or transported by itself, and there is a problem in handleability.

Also, in order to improve the sealing property of
A seal mechanism which is expandable and contractible on the outer periphery of the partition wall, for example, a rubber rod-like seal member attached to a slide rod which can protrude outward (see Japanese Utility Model Application Laid-Open No. 63-188489);
There is also proposed a tire tube-shaped one which is stretched left, right, up and down by air filling. However, as in the operation of the slide bar and the filling with air, the time required for installing the partition wall is required, and there is a problem in the ease of handling. Further, as disclosed in Japanese Utility Model Registration No. 3017734, there has been proposed a device in which the outer periphery of the partition wall and the inner surface of the luggage compartment are fitted with irregularities. And the luggage compartment cannot be partitioned at an arbitrary position in the front-rear direction, resulting in poor handleability.

[0007] In view of the above-mentioned current situation of partition walls, an object of the present invention is to provide a partition wall for a refrigerating car or a refrigerated car, which has both heat insulating property, robustness, handleability, and sealing property. And

[0008]

According to a first aspect of the present invention, there is provided a hollow resin having a synthetic resin foam plate and a plurality of parallel ribs attached to both surfaces of the synthetic resin foam plate. A partition wall for a refrigerating car or a refrigerated car, comprising a plate and a flexible sealing member provided at a necessary portion around the synthetic resin foam plate.

The above-mentioned synthetic resin foam plate provides high heat insulating properties due to the low thermal conductivity based on the foam structure. The hollow resin plate having a large number of parallel ribs stuck on both sides of the synthetic resin foam plate has strength while being lightweight based on the rib structure, and also has high heat insulation due to an air layer between the ribs. Therefore, the synthetic resin foam plate and the hollow resin plates on both sides thereof can provide a structure having high heat insulation, high strength, and light weight as a whole. In addition, a flexible sealing material in a suitable position around the outer periphery of the synthetic resin foam plate follows irregularities of the luggage compartment wall, suppresses generation of unnecessary gaps, improves sealing performance, and improves the sealing performance of the partition wall. By operating the handle provided at the, the seal is exerted by a simple operation of pushing the partition wall into the appropriate place in the luggage compartment.

The seal member is preferably provided at a portion where the both sides of the luggage compartment wall and the ceiling surface are in contact with each other, but a portion where the seal member is in contact with the floor surface is not necessarily required. Further, the laminated plate composed of the synthetic resin foam plate and the hollow resin plates on both sides thereof does not need to be a single plate, but may be two or more connected so as to be folded. Further, a protective skin may be provided on the surface of the laminate as required, or a hard synthetic resin foam plate for protection may be attached to the outer periphery of the laminate. Also, for members exposed on the surface, such as the outer skin of the laminate,
A process of kneading one or more of an antibacterial agent and a fungicide can be applied to prevent the growth of various bacteria.

The invention of claim 2 is characterized in that the ribs of the hollow resin plate adhered to one of the two surfaces and the ribs of the hollow resin plate adhered to the other surface of the two surfaces. It is a partition wall for refrigeration vehicles or refrigeration vehicles of Claim 1 which crosses.

Since the direction of the ribs of one hollow resin body and the direction of the ribs of the other hollow resin plate intersect, the strength of the laminated plate composed of the synthetic resin foam plate and the hollow resin plates on both surfaces thereof is further increased. growing. The preferred mode of intersection is orthogonal such that one rib is transverse and the other rib is longitudinal.

According to a third aspect of the present invention, the seal member has a flexible synthetic resin foam material disposed around the periphery and an elastic cloth covering the synthetic resin foam material. A partition wall for a refrigerating car or a refrigerated car according to claim 1 or 2.

The sealing member is made of a flexible synthetic resin foam material,
Since it is a stretchable cloth enclosing the synthetic resin foam material, it follows irregularities on the inner wall of the cargo room and reliably seals a gap with the inner wall. The elasticity of the cloth needs to expand and contract at least in the direction along the outer periphery, but may also expand and contract in the direction perpendicular to the direction along the outer periphery. Such a cloth can be produced, for example, by selecting a knitting method and a yarn to be used.

According to a fourth aspect of the present invention, there is provided the partition wall according to the third aspect, wherein a waterproof layer made of a synthetic resin is provided on at least one surface of the cloth.

[0016] Since a waterproof layer made of a synthetic resin is provided on at least one surface of the stretchable cloth for enclosing the synthetic resin foam material of the seal member, infiltration of water into the seal member is prevented. Freight or refrigerated car luggage compartments are often cleaned. In particular, since a flexible synthetic resin foam has water absorption due to open cells, if it contains water, it freezes and loses flexibility, so that a waterproof layer is effective. If necessary, the outer surface of the cloth can be subjected to a water-repellent treatment to prevent the cloth from freezing. Further, the surface of the cloth can be subjected to an antibacterial treatment or a fungicide treatment to prevent the propagation of various bacteria.

According to a fifth aspect of the present invention, the foamed sheet of a synthetic resin is adhered to the surface of the hollow resin plate, and the synthetic resin sheet is further adhered to the surface. It is a partition wall for a freezing car or a refrigerator car. The surface of the hollow resin plate is made flexible and protected by the synthetic resin foam sheet and the synthetic resin sheet.

According to a sixth aspect of the present invention, a flexible synthetic resin sheet is adhered to one side of a butted portion of the two panels, the panel including the synthetic resin foam plate and the hollow resin plate. Claim 1 which can be folded in two
5. A partition wall for a refrigerating car or a refrigerated car according to any one of 5. Since the partition wall can be folded in two, it can be easily installed by being deployed at a predetermined position in the luggage compartment, and is not bulky when stored.

Then, a flexible synthetic resin sheet 17 such as a PVC tarpaulin is adhered to one surface of the butted portion of the panels A and B, and has a structure that can be folded in two in a hinge shape. When the partition wall 1 is stored in the luggage compartment wall, it is folded in two and stored along the inner wall. It can also be carried out of the luggage compartment and stored in a warehouse or the like. When partitioning the freezer compartment by the partition wall 1, the panel A,
B is unfolded and installed at an appropriate place on the interior wall of the luggage room to form one partition wall 1.

On the lower side of the panels A and B, since the weight of the partition wall 1 is added to the floor of the luggage compartment, a 10-fold polyethylene foam 18 having a small compression strain is adhered.
Further, even the one covered with the PVC sheet 19 can be sufficiently sealed. Therefore, the sealing member 6 having the flexible structure described with reference to FIG. 1 is provided around the upper side of the partition wall 1 and around both side surfaces after being developed. Since the seal member 6 is arranged in a state of being pressed against the wall of the luggage compartment, the partition wall 1 has a height and a width of 20 to 30 mm in advance of the inner size of the luggage compartment.
It is set to be 30 mm larger.

A handle 11 is provided on one side of each of the panels A and B.
Is attached. The handle 11 has both ends fixed to the panel surface with metal fittings so that the belt has a sufficient length. Since each of the panels A and B has a rigid polyethylene hollow resin body, the fitting can be fixed by a fastening member that reaches the polyethylene hollow resin body. Above and below the panels A and B on the side where the handle 11 is provided,
Two metal fittings 20 through which the fixing belt 12 can be inserted are fixed on each of the upper and lower sides, two on each side.

Next, the use state of the partition wall 1 having the above-described structure will be described with reference to FIG. FIG. 3 is a view of the luggage compartment 20 of the refrigerating car and the refrigerator car with the door 21 opened, as viewed from the rear. As shown in FIG.
A plurality of rails 23 are fixedly provided, and the rails 23 are provided with a large number of locking portions 24. The rail 23 is also called a lashing rail, and is provided for fixing one end of a belt for a fastener for fixing cargo in the luggage compartment. The rail 23 protrudes from the side wall 22 of the luggage compartment 20, and it is important that the partition wall 1 also exerts a sealing function on this portion.

When the partition wall 1 is installed, the handle 11 provided on the panels A and B is held at a predetermined position in the luggage compartment 20 by hand, and the sealing member 6 is pressed against the ceiling and the side walls of the luggage compartment.

EXAMPLES Further, the heat insulation performance when the partition wall according to the present invention is used in a luggage room will be described based on specific examples.
A freezer having a length of 1860 mm, a length of 2090 mm and a length of 6000 mm, which simulated a luggage compartment, was used. On both sides of this freezer, two upper and lower lashing rails installed on an actual truck bed are set. The partition wall 1 having the structure described with reference to FIG. 1 and FIG. The weight of the partition wall having a size corresponding to the above-mentioned freezer is about 19 kg, and the operator can easily install the partition wall alone. And the anterior chamber side is frozen at minus 25 ° C,
The temperature change with time on the rear chamber side was measured. The result is
As shown in FIG.

According to FIG. 4, the temperature of the rear chamber drops from the outside air temperature (22 to 24 ° C.) with the passage of time.
Even after 18 hours, the temperature was not negative at 5 ° C.
It can be seen from the temperature drop curve that the rear chamber side does not become negative until a considerable time has elapsed. During the time required for transporting a normal freezer truck, the rear room is kept at 0 ° C. or higher even if the front room is frozen. Therefore, it is possible to load luggage that should not freeze in the rear room. In the case of the conventional example in which urethane foam was filled between 75 mm thick aluminum molds, the temperature reached 0 ° C. after 12 hours.
