。The above patent application is similar to a part of the embodiment of the present application, and to explain it using the embodiment of the present application, in a storage having a top opening door (2) that opens and closes the top opening of the main body with a hinge device (3). , the door (2) has a gasket (28) that comes into contact with the periphery of the opening, and the hinge device includes a sliding shaft (13) that protrudes parallel to the hinge shaft (6) that is the center of rotation of the door; A sliding groove (15) is provided in which the sliding shaft reciprocates as the door rotates, and the sliding groove has an outer diameter equal to or slightly larger than the outer diameter of the sliding shaft in the closed position and the fully open position of the door. The wall is large and elastically deforms between the two positions due to the strong acting force accompanying the reciprocating movement of the sliding shaft. The difference from the embodiment of the present application is that the hinge hole (14) is circular and the circular hinge shaft (6) is inserted without any play.

係である貯蔵庫の扉開閉装置である。The means includes a storage having a top-opening door (2) that opens and closes the top opening of the main body (1) with a hinge device (3);
The door has a gasket that comes into contact with the periphery of the opening, and the hinge device has a hinge hole (14) that is the center of rotation of the door.
A sliding shaft (13) protruding parallel to the hinge shaft (6) inserted into the door, and a sliding groove (15) in which the sliding shaft reciprocates as the door rotates are provided. Between the closed position and the fully open position of the door, the groove forms a wall that is elastically deformed by the strong acting force accompanying the reciprocating movement of the sliding shaft, and the groove has a wall that is elastically deformed by the strong acting force accompanying the reciprocating movement of the sliding shaft, and the groove has a wall that is elastically deformed by the strong acting force accompanying the reciprocating movement of the sliding shaft. The relationship between one end of the sliding groove is such that when the door reaches just before the closed position from the open position, the door falls slightly toward the main body to achieve sufficient contact of the gasket with the main body. This is a related storage door opening/closing device.

), when the opening/closing operation is stopped, the sliding shaft (13) will hold the sliding groove (15) in a state where it is elastically deformed at the contact part, so the door (2) will not move in place. It stops at When the door is further moved, the sliding shaft moves while elastically deforming the sliding groove. When closing the door (2), the resistance between the sliding shaft and the sliding groove is sufficiently large, so the hinge shaft is positioned at the lower end of the hinge hole, and the door (2) rotates with it slightly lifted upwards. .For this reason, the gasket on the hinge side moves away from the main body, and the gasket does not cause large twisting due to the closing operation of the door.And when the door approaches the closing position, the resistance of the sliding shaft due to the sliding groove suddenly increases. As the gasket lowers, it will fall slightly toward the main body, allowing the gasket to come into close contact with the main body.

防止の作用をする。Relationship of hinge hole (14) to hinge shaft (6) and sliding groove (15) to sliding shirt (13)
The relationship is that when 5 (2) rotates and reaches the position immediately before closing, where the door is fully opened from the open position, the door (2) falls slightly toward the main body (1) and the back side of the door (2) This is a loose relationship that achieves sufficient abutment of the gasket (28), which is annularly attached to the peripheral edge, against the main body (1). This will be explained in more detail. The hinge hole (14) is the door (2)
is a long hole that extends in the vertical direction when in the closed state, and the hinge shaft (6) can easily move up and down within the long hole. In addition, the size of the starting end (16) is such that when the sliding shaft (13) enters the starting end (16) of the sliding groove (15), the side (29> on the hinge device side of the door (2) can move downward slightly). The door outer panel (12) has front, rear, left and right side walls and flanges (25) formed by bending steel plates, and notches (25) are formed at the left and right corners of the front wall.
19) and (20) are each covered with a corner cap (21). The corner cap (21) is a molded product made of soft synthetic resin, and has an elastic pawl (22) that is elastically deformed and inserted into the cutout portions (19) and (20), and is engaged with the periphery of the cutout portion.
, flanges (23) and (24) that come into contact with the front and left and right side surfaces of the door outer panel (12), and a flange (26) that comes into contact with the upper surface of the door outer panel (12) and the lower surface of the lower bent flange (25). (
27) are integrally formed. The door (2) is the door outer panel (1
2) The back side space is filled with foam insulation material by foaming on site and adhered to maintain strength. After this foaming, the door inner plate (18)
Attach the gasket (28) to the periphery. Since the hinge caps (7) are attached to the left and right rear ends of the door outer panel (12), they also act as reinforcing materials at the corners between the left and right side walls and the rear wall of the door outer panel (12). ) to prevent twisting.

じないような大きさになっている。In the above configuration, the door (2> is the hinge shaft (6)
When the sliding shaft (13) is rotated around the hinge hole (14) and closed, the sliding shaft (13) is located at the starting end (16) of the sliding groove (15). When the door (2) is fully opened, the sliding shaft (13) is located at the end (17) of the sliding groove (15). When the door (2) is fully open, the sliding shaft (13) is located at the end (17) of the sliding groove (15). ), the end (17) also acts as a stop. Between fully opening and fully opening the door (2), the sliding shaft (13) receives a strong frictional force from the wall of the sliding groove (15) as the door (2) opens and closes. If the door (2) is stopped halfway, the door (2) is held in that state.At the end (17) and start end (16), a sliding groove (15) is formed by the sliding shaft (13) in order to prevent the hinge cap (7) from deteriorating. ) is so large that little or no elastic deformation occurs.

り又は破損したりしないことになる。In the above-mentioned operation, a particularly important point is when the door (2) is rotated from the open position to the closed position. That is, the fifth
When the door (2) is fully open as shown in the figure, the sliding shaft (13)
is located at the terminal end (17) of the sliding groove (15), and the hinge shaft (6) is close to the - end (upper end when viewed with the door closed) of the hinge hole (14). From this state, the door (
2) When rotated in the closing direction, the sliding shaft (13)
The frictional resistance between the sliding groove (15) and the hinge shaft (6)
The sliding shaft (13) is sufficiently larger than the frictional resistance between the door (2) and the hinge hole (14) during the closing operation.
When the hinge shaft (6) is rotated slightly to move to the other end of the hinge hole (14) (the lower end when the door is closed), and the door (2) is further rotated in the closing direction, the sixth
It will be in the state shown in the figure. When the door (2) is further closed from this state and just before reaching the closed position shown by the two-dot chain line in Fig. 7 (this state is shown by the solid line position in the same figure), the sliding shaft (13) slides. As the sliding shaft (13) begins to enter the starting end (16) of the groove (15), the large frictional resistance of the sliding shaft (13) that had been received by the sliding groove (15) decreases rapidly, and the door (2) (1), so that the gasket (28) is in close contact with the main body (1), and in this state, the hinge shaft (6) is located at the other end, that is, the upper end, of the hinge hole (14), and the sliding shaft ( 13) is located within the starting end (16) of the sliding groove (15).As is clear from the above operation, in the solid line state in Fig. 7, the hinge shaft (6
) is located at the lower end of the hinge hole (14), and the side (29) on the hinge device (3) side of the door (2>) is in the dimensional relationship of the long hole of the hinge hole (14>) with respect to the main body (1). As a result, the gasket (28) is in a state slightly floating from the main body (1) or in a state in which it is in slight contact with the main body (1).For this reason, when the door (2) is closed, The gasket (28) will not get caught on the upper end of the body (1) and become twisted or damaged.

半開したときの状態を示している。As shown by the two-dot chain line in Figure 7, the door (2) is moved from the closed state to the
), the sliding shaft (13) immediately enters the narrow part of the sliding groove (15) and the door (2) is opened while receiving strong frictional resistance as described above. This shows the state when the door is approximately half open.

らない。When opening the door (2), if the hinge shaft (6) is located at the upper end of the hinge hole (14), the gasket (2)
8) is not pressed. Since the gasket (28) twists and remains in that state for a long time when the door (2) is closed, twisting when opening the door (2) does not pose much of a problem.

Therefore, if the door is stopped midway through opening or closing, the door can be maintained in that state, improving operability. Furthermore, since no springs are used, the structure is simple, and the structure can be easily assembled. Furthermore, when the door moves from the open position to the closed position, the gasket is rubbed strongly by the main body and the door is moved slightly upwards relative to the main body so that the gasket does not twist. The gasket will not close and cause a seal failure, and the gasket will not be deformed or damaged due to twisting.
