Description

DETAILED DESCRIPTION OF THE INVENTION The present invention aims to provide a special hinge device that is capable of operating a hinge-operated opening/closing door and a second sliding door.

An embodiment of the present invention will be described below with reference to the drawings.

First, FIG. 1 is a perspective view of a refrigerator using the hinge device of the present invention in an open hinge state, and FIG. 2 is a perspective view of the refrigerator in a sliding state with a sliding door. This will be explained mainly using the perspective view of FIG.

A first member 5, 5' attached to a fixed frame on the upper periphery of the refrigerator main body 1, and opening/closing doors 3, 4 that serve as a lid of the refrigerator main body 1.
The second member attached to 6. ff, and the first members 5, 5' and the second members 6, 6'
are mutually pivotable, and the first members 5, 5'
is fixed to the pivot shaft 7, and the second member 6. a cylinder body 8 with a C-shaped cross section that fits into the pivot shaft 7; At the same time, this segment 8. A groove 10 for locking in the rotational direction is provided at the joint 8. It can be fitted into the groove 10 of the
Further, locking pieces 11, 11' that fit into the open portions 91g of the joints 8, 8' and are movable in the axial direction as indicated by the arrow X are fixed to the pivot shaft 7. ' is the cylindrical body 8. When the pivot 7 is located in the open part 9, 9' of the
The first member fixed to 5. The fixed portion of the cylindrical body fits into the opening 9, and is formed to a size that passes through the opening 9, so that the groove 10, 1σ of the cylindrical body 8° and the locking piece 11° of the pivot shaft 7 are formed. 11' corresponds to the first member 5° and the second member 6. ff is capable of a hinge operation, and also has an open portion 9.ff of the cylinder bodies 8, 8'. When the locking piece 11 of the pivot shaft 7 is located at ff, the second member 6
．． σ can be moved in the axial direction.

In such a configuration, when each opening/closing door 3, 4 is simply opened/closed by the hinge as shown in FIG. 1, the locking piece IL11'
The opening/closing door 3 corresponds to each cut groove 10.10'.
, 4 are opened and closed, the cylindrical bodies 8 and 8' rotate about the pivot 7 as shown by the arrow Y, thereby performing a hinge operation.

In addition, as shown in FIG. 2, in order to slide one of the opening and closing doors 3 along the opening surface of the refrigerator body 1 in a sliding door manner, with the opening and closing door 3 closed in this way, the locking piece 11 It is only necessary to set it so that it is located in the open part 9 of the cylinder body 8.

With this position, the cylindrical body 8 can be moved in the axial direction with respect to the pivot shaft 7.

That is, the second member 6 and the cylinder 8 move in the axial direction with respect to the pivot 7 together with the pulling operation of the opening/closing door 3, and at this time, the second member 6 and the cylinder 8 move in the axial direction with respect to the pivot 7.
The member 5 passes through the opening 9 and this axial movement can be carried out until the ring 12 abuts the first member 5.

In this way, by using this hinge device, it is possible not only to open and close the door, but also to operate it like a sliding door.
This can be applied to special specification refrigerators such as the one shown in the figure that require double-sided operation.

In this embodiment, one of the doors is moved in the axial direction, but if necessary, the door 4 can be moved in the axial direction following the axial movement of the door 3.

Furthermore, if the first member 5' is made to have the same structure as the other first member 5 so that it can pass through between the openings, the opening/closing door 4 can be independently slid in that direction. can.

In addition, in this embodiment, a long shaft shared by the two opening/closing doors 3 and 4 is used, but it is of course possible to have a structure in which one pivot and one segment correspond to one opening/closing door. be.

As described in detail above, this invention consists of a first member attached to a fixed frame and a second member attached to an opening/closing door.

In a hinge device in which the two members pivot relative to each other, one of the two members is fixed to a pivot shaft, the other member is fixed to a cylindrical body with a C-shaped cross section that fits into the pivot shaft, and A groove for axial locking is provided in the body, and a locking piece that can be fitted over the cylinder body and movable in the axial direction at the open portion of the joint body is fixed to the pivot shaft, and the locking piece is fixed to the shaft. is in the open part of the cylinder, the member fixed to the pivot corresponds to the open part and is configured to have a size that passes through the hole, and the locking piece is in the position corresponding to the groove. Both members have a hinge action and are configured to be able to move in the axial direction when the locking piece is located in the open part of the cylinder, so the sliding door 2 can be moved in conjunction with the hinge action opening/closing door. Therefore, it can be used as a hinge device for opening/closing doors that require such special specifications.

Claims (1)

[Scope of Claims] 1. A hinge device consisting of a first member 5 attached to a fixed frame and a second member 6 attached to an opening/closing door, both members 5.6 pivoting relative to each other. The first member 5 is defined by a pivot shaft 7, the second member 6 is fixed to a cylinder body 8 having a C-shaped cross section and fitted onto the pivot shaft 7, and a groove 10 for rotational locking is provided in the cylinder body 8. A locking piece 11 that can be fitted into the groove 10 of the cylinder body 8 and can be fitted into the open part 9 of the cylinder body 8 to move in the axial direction is fixed to the pivot shaft 7. When the stopper 11 is located in the opening 9 of the cylinder 8, the fixed portion of the first member 5 fixed to the pivot 7 fits into the opening 9 and is large enough to pass through the opening 9. By forming the groove 10 of the cylindrical body 8. The first member 5 and the second member 6 can be hinged at positions where the locking pieces 11 of the pivot shaft 7 correspond, and the locking pieces 11 of the pivot shaft 7 are attached to the open portion 9 of the cylinder body 8. The hinge device is characterized in that the second member 6 is movable in the axial direction when the second member 6 is positioned.
