Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an in-body partitioning device for partitioning a body of a refrigerator car or the like with a movable partition.

[Background Art] The cooling temperature required for transporting dairy products, frozen foods, meats, and the like differs for each article. Therefore, in order to partition each article having a different cooling temperature or to change the partition volume in accordance with the transport amount, a rubber plate or the like is fixed to the outer periphery of the partition movable in the body, and the rubber plate is fixed. Some are always in close contact with the inner wall of the body.

Further, as disclosed in Japanese Patent Publication No. 41-22209, a groove having a bottom is formed around the partition wall, and a flexible bullet tube is flexibly inserted into the groove having the bottom to prevent air from being filled. There is a gap between the bullet tube and the inner surface of the body to facilitate the movement of the partition wall. The bullet tube filled with air has an inner peripheral surface that strongly presses the bottomed groove and an outer peripheral surface that is the inner surface of the body. Press
In some cases, the inside of the body is partitioned in a sealed manner.

However, if a rubber plate or the like is strongly pressed against the inner surface of the body, the frictional resistance between the seal member and the inner surface of the body when moving the bulkhead increases, which may hinder the movement of the bulkhead. there were. For this reason, in order to easily move the partition wall, there has been a problem that the hermeticity must be sacrificed to some extent.

Further, the one disclosed in the above publication requires an air supply means such as a compressor or an air pump for filling the bulleted tube with air, which causes an increase in cost and increases the weight of the vehicle. There was a problem.

The present invention has been made in view of the above problems,
An object of the present invention is to provide a partitioning device in a body such as a refrigerating vehicle that can easily move a partition that partitions the inside of the body.

`` Means for solving the problem''A partitioning device in a body such as a freezing vehicle of the present invention for solving the above-described problem is a partitioning device in a body that partitions a body such as a freezing vehicle with a movable partition. A corner member disposed in each corner of the partition wall and movable in a diagonal direction of the partition wall; and a corner member provided at an end of four sides of the partition wall, and a space between adjacent ends is closed by the corner member. A support member that moves in a direction orthogonal to the four sides of the partition wall in conjunction with the corner member, and is supported by the corner members and the support members, and is stretched around the partition wall. An endless weather strip that can be extended and retracted, and a link mechanism that causes the corner members to move in the diagonal direction.

[Operation] In the body partitioning device for a refrigerator car or the like according to the present invention having the above-described configuration, the corner member for closing the end between the adjacent support members by operating the link mechanism is projected diagonally from each corner of the partition wall. Then, in conjunction with this, each support member provided on the end face of each of the four sides of the partition moves outward in a direction orthogonal to each side to increase the area of the partition toward four directions. Since the endless weatherstrip is supported by the corner member and the support member, the weatherstrip is pressed against the corners and the inner surface of the body to partition the inside of the body into a substantially hermetic shape. Further, when the corner member is pulled in the diagonal direction by operating the link mechanism, the respective support members move together and the area of the partition wall is reduced, and the weather strip is separated from the inner surface of the body.
