The upper opening / closing door 2 is formed of a heat-insulating member, and one end in the width direction is connected to the cool box main body 1 by a plurality of hinges 2a. In this case, the upper door 2
As shown in FIG. 4, is formed above the height H from the lower end of the cool box main body 1, that is, above the side wall 12 of the bed 11 of the vehicle 10. A lock member 2b having a well-known structure is attached to the other end in the width direction of the upper opening / closing door 2, and the locking member 2b locks and unlocks the upper opening / closing door 2 to / from the cold storage main body 1 by a predetermined operation. Has become.

The lower opening / closing door 3 is formed of a heat-insulating member, and one end in the width direction is connected to the cool box main body 1 by a plurality of hinges 3a. A lock member 3b equivalent to that described above is attached to the other end in the width direction of the lower opening / closing door 3.

A spacer 4 made of a material having low frictional resistance, such as a synthetic resin, is provided on a lower end surface of each of the doors 2 and 3 at the other end in the width direction. The spacer 4 on the side of the lower opening / closing door 3 is in contact with the upper end surface of the opening / closing door 3 and is in contact with the upper end surface of the front opening edge of the refrigerator compartment body 1. Each spacer 4 has an inclined surface 4b inclined downward toward the center in the front-rear direction on the front end side of the lower surface.
And each of the open / close doors 2 is provided by a plurality of screws 4a.
It is fixed to 3.

Further, a plurality of stoppers 5 are attached to one end side in the width direction of the upper opening / closing door 2 and the cool box main body 1, and each of the stoppers 5 is rotated when the upper opening / closing door 2 rotates to a predetermined rotation position in the opening direction. They come into contact with each other.

The in-vehicle cool box configured as above is
As shown in FIG. 4, it is mounted on a carrier 11 of a vehicle 10 composed of a small truck, and is fixed to the carrier 11 by a rope or a belt (not shown). In this case, the cold storage main body 1 is arranged with the front face facing the rear of the vehicle 11, and the product is put in and out of the cold storage main body 1 by opening and closing the upper opening / closing door 2 from the rear of the loading platform 11. That is, in the in-car cool box, for example, a product such as milk is stored in the cool box body 1, and the product is transported from a retail store or the like to a delivery destination while the product is kept cool in the cool box body 1. In this case, since the upper opening / closing door 2 of the cool box is formed above the rear side wall 12 of the vehicle 10, the upper opening / closing door 2 is placed with the front side of the cool box main body 1 close to the rear end of the vehicle 10. 2 can be opened and closed, and the product can be easily taken out at the delivery destination or the like. Furthermore, if the side wall 12 of the vehicle 10 is opened and both the opening and closing doors 2 and 3 are opened, it is possible to easily store goods in a retail store or the like.

When the doors 2 and 3 are closed, the spacer 4 on the upper door 2 abuts on the upper end surface of the lower door 3 and the spacer 4 on the lower door 3 is closed. Because it comes into contact with the upper end surface of the front opening edge of the main body 1,
Even when vibration or impact is applied during running of the vehicle, the doors 2 and 3 do not move up and down. In addition, in the cool box, for example, when closing the upper opening / closing door 2 from the open state, as shown in FIG.
When b contacts the upper edge of the lower door 3, the upper door 2 is guided upward by the inclined surface 4b as shown in FIG. In this case, it goes without saying that the spacer 4 on the side of the lower opening / closing door 3 also has the same function as described above. Further, as shown in FIG. 7, the upper opening / closing door 2 is rotated in the opening direction, and as shown in FIG. The stopper 5 comes into contact with each of the stoppers 5 on the side of the cold storage main body 1, and the rotation of the upper door 2 is restricted.

Since the spacer 4 is provided on the lower end surface of the cold storage body 1 and is in contact with the upper end surface of the front opening edge of the cool box main body 1, the opening and closing doors 2 and 3 move up and down even when vibrations or shocks are applied during running of the vehicle. Therefore, accidental unlocking of the lock members 2b, 3b due to such vibration or impact can be reliably prevented. Therefore, it is not necessary to use expensive lock members having high lock strength for the lock members 2b and 3b, and the cost can be reduced. In addition, since each spacer 4 is attached to the lower end surface of each opening / closing door 2, each spacer 4 is not easily seen from the outside, and it is possible to prevent the appearance from being deteriorated. In this case, since the spacer 4 on the side of the lower opening / closing door 3 does not exist on the side of the refrigerator box 1 when the door is opened, there is an advantage that the spacer 4 does not hinder the taking in and out of the product.

Each of the spacers 4 is provided with an inclined surface 4b which comes into contact with an upper edge of the lower opening / closing door 3 (or a front opening edge of the cool box main body 1), and the upper opening / closing door 2 (or the lower opening / closing door 3) is formed by the inclined surface 4b. ) Is guided upward when the door is closed, so that even when the upper door 2 (or the lower door 3) is partially bent, the closing operation of each of the doors 2 and 3 is always performed smoothly. Can be. In this case, since the spacer 4 is formed of a material having low frictional resistance, the closing operation of each of the doors 2 and 3 can be performed more smoothly.

Further, since the cool box is provided with the stopper 5 for restricting the opening of the upper opening / closing door 2 beyond a predetermined turning position, the turning operation which exceeds the opening limit of the upper opening / closing door 2 is prevented. Thus, it is possible to reliably prevent the lock member 2b from being damaged by such an operation.

In the above-described embodiment, the stoppers 4 are provided on both of the doors 2 and 3.
Since the door is not frequently opened and closed, the stopper 4 on the side of the lower opening / closing door 3 may be omitted as appropriate. In the above embodiment, the stopper 5 for the lower door 3 is omitted from the viewpoint of the frequency of opening and closing of the lower door 3.
Needless to say, a stopper may be provided.

FIGS. 9 and 10 show a second embodiment of the present invention, which is a modified example of the spacer provided on the upper door 2. FIG. That is, the spacer 6 shown in the figure has an inclined surface 6a inclined downward toward the center in the front-rear direction on the front end side and the rear end side of the lower surface, and the inclined surface 6a on the front end side is the rear surface of the lower opening / closing door 3. Contact the upper edge of the side, and the inclined surface 6 on the rear end side.
a contacts the upper edge of the lower opening / closing door 3 on the front side. Thus, when the upper opening / closing door 2 is closed with the lower opening / closing door 3 closed, similarly to the above-described embodiment, FIG.
As shown in FIG.
Is guided upward. When the lower opening / closing door 3 is closed with the upper opening / closing door 2 closed, or when the lower opening / closing door 3 is closed first from the state where both the opening / closing doors are opened, as shown in FIG. The upper opening / closing door 2 is guided upward by the inclined surface 6a on the side. Therefore, no matter which one of the doors 2 and 3 is opened and closed, each door 2 and 3 is opened and closed.
The closing operation of No. 3 can always be performed smoothly.

FIG. 11 and FIG. 12 show a third embodiment of the present invention, and the mounting position of the spacer is different from that of the third embodiment. That is, the spacer 7 shown in the figure has the same inclined surface 7a as the first embodiment on the upper surface on the front end side, and the upper end surface of the lower opening / closing door 3 as shown in FIG. It is attached to the upper end surface of the front opening edge of the cool box main body 1.

As a mounting example of a spacer other than the above-described embodiment, the spacer may be mounted on the lower end surface of the upper opening / closing door 2 and the upper end surface of the front opening edge of the cool box main body 1 or on the lower opening / closing door 3. You may make it attach to an end surface and a lower end surface, respectively.

[0026]

As described above, according to the insulated refrigerator according to the first and second aspects of the present invention, the opening / closing door does not move up and down even when vibration or impact is applied during running of the vehicle. Even if a lock member having a high lock strength is not used for the lock member of the door, accidental opening of the door can be reliably prevented. Further, when the spacer is attached to the lower end surface of the upper opening / closing door, the spacer is not easily seen from the outside, so that the appearance can be prevented from being deteriorated.

According to the insulated refrigerator according to claims 3 and 4, in addition to the effects of claim 1 or 2, the operation of closing the opening / closing door can always be performed smoothly, which is extremely advantageous in practical use. .

[0028] According to the in-vehicle cool box of claim 5,
In addition to the effects of claims 1, 2, 3 or 4, damage to the member that rotatably connects the door to the cold storage main body can be prevented because a rotation operation exceeding the opening limit of the door can be prevented. For example, when the front of the refrigerator compartment is mounted on the back of the vehicle with the front face facing backward, the opening and closing door can be prevented from opening wider than the side of the vehicle. It is safe because it does not come into contact with the pedestrians on the side of the vehicle.
