Generally, a refrigerator is a device capable of storing various foods for a long time by a refrigeration cycle using a refrigerant. In general, a refrigerator is a freezer for preserving foods that require long-term storage in a frozen state, and unlike the freezer, a refrigerator can be stored for a short time without freezing. It is divided into a fridge for storing food to maintain freshness without spoiling. Classically, the refrigerator has a freezer compartment at the upper side of the refrigerator, and a refrigerating chamber at the lower side of the refrigerator. In recent years, the larger refrigerator has a freezer compartment on the left side of the refrigerator and a refrigerator compartment on the right side.

Such a refrigerator is equipped with a freezer compartment door through hinges at the upper and lower ends of the left end, and a refrigerator compartment door is mounted at the upper and lower ends of the right end. In addition, holders are mounted on the upper and lower portions of each door in order to conveniently open and freeze the doors of the freezer compartment and the refrigerating compartment, and handles in the shape of handles or rods are formed between the upper and lower holders.

However, such a conventional refrigerator has to put down an object and open the door again when the object is put in or out of an object by both weights when the door is opened or closed by itself when the object is stored or removed after the door is opened. There is a problem of taking the inconvenience. This phenomenon occurs particularly badly, even when the refrigerator is not installed completely flat, but only slightly inclined, which causes inconvenience to the use of the refrigerator. That is, in order to secure the sealing force of the refrigerator, it is common to lower the rear part of the refrigerator, so that it operates in the direction of closing its own weight within a predetermined angle and in the direction of opening more than that. This is a problem.

The present invention is to overcome the problems of all refrigerators installed in a conventional manner, an object of the present invention is to stop the opening of the door at a predetermined angle, thereby preventing the door from opening or closing itself by its own weight SUMMARY OF THE INVENTION An object of the present invention is to provide an opening angle stop device for a door for a closed mechanism.

In order to achieve the above object, the present invention is characterized in that in the opening angle stop device of the door for a closed mechanism, the door is stopped after opening the predetermined angle, so that the opening angle does not move under a certain force.

Here, the stopper member may have a groove having a predetermined depth in the door, and the groove may be moved up and down, and may be provided with a fixed shaft coupled to and separated from the fixing groove of the fixing plate.

In addition, the fixed shaft may be further interposed with a spring to allow the fixed shaft to move up and down elastically.

In addition, the door may be further provided with a separation prevention plate so that the fixed shaft is not separated to the outside.

In addition, a plurality of fixing grooves formed in the fixing plate may have a predetermined angle.

As described above, the present invention has the advantage that the door is fixed by the stopper after the door of the sealing mechanism is opened at a predetermined angle, so that the door is not opened or closed by its own weight and is convenient in use.

Furthermore, the present invention has the advantage that even if the closing mechanism is installed in a position that is not completely flat, since the door is fixed without moving in an open state at an angle, the position of the closing mechanism does not need to be exactly horizontal.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings such that those skilled in the art may easily implement the present invention.

1 is a front view showing a refrigerator to which the present invention is applied.

As shown, for example, the refrigerator 100 is equipped with a freezer compartment door 110 on the left side, and a refrigerator compartment door 120 on the right side. In addition, the freezing compartment door 110 is rotatably coupled to the freezer compartment body (not shown) by interposing the upper hinge 130 on one side, the refrigerating compartment door 120 also includes an upper hinge 140 on one side of the refrigerating compartment body ( (Not shown) is rotatably coupled. Of course, each door is hinged to the lower portion is coupled to each body, but this is not the gist of the present invention will be omitted. In addition, the freezer door 110 has holders 111 and 112 mounted at upper and lower ends thereof, respectively, and a handle or a substantially rod-shaped rotation that is recessed between the holders 111 and 112 so as not to protrude to the surface. Possible handle 113 is mounted. Furthermore, holders 121 and 122 are mounted on the upper and lower ends of the refrigerating chamber door 120, respectively, and a rotatable handle 123 having a substantially rod shape is mounted between the holders 121 and 122. On the other hand, the lower cover 150 is provided below the respective doors 110 and 120. Such, the refrigerator 100 is only one form for understanding the present invention, the door opening angle stop device according to the present invention can be used in various sealing mechanisms.

Fig. 2A is a partial plan sectional view showing the opening angle stop device of the door for a closed mechanism according to the present invention, and Fig. 2B is a sectional view taken along the line 2b-2b in Fig. 2A. Here, the opening angle stop device is described with an example mounted on the refrigerating chamber body 170 and the refrigerating chamber door 120, it can be applied to any door that can be automatically closed as well as the freezer body and the freezer door. .

As shown, the opening angle stop device of the door for a closed mechanism according to the present invention includes a hinge 140, a rotating shaft 161, a fixing plate 162, and a stopper member 164.

One side of the hinge 140 is fixed to the refrigerator body 170, and the other side of the hinge 140 extends a predetermined length toward the door 120.

The rotating shaft 161 is rotatably coupled to one side of the refrigerator door 120, the other side is fixed to the hinge 140. Accordingly, the door 120 may be rotated by a predetermined angle about the rotation shaft 161 to be opened at a predetermined angle from the refrigerator body 170.

The fixing plate 162 has a shape in which two disks are in contact with each other. The fixing plate 162 is a circumference of the rotation shaft 161 and is coupled to the hinge 140. In addition, the fixing plate 162 is formed with at least one fixing groove 163 on the surface facing the door 120. Three fixing grooves 163 are formed in the drawing, but it is natural that a larger number or a smaller number may be appropriately formed. In the drawing, the fixing groove 163 may be formed at 0 °, 45 °, and 90 ° about the rotation shaft 161. Accordingly, it can be seen that the door 120 coupled to the hinge 140 and the rotation shaft 161 can be fixed and stopped at 0 °, 45 ° and 90 °, respectively, about the rotation shaft 161. Of course, such an angle is only one example, it is obvious that the ordinary expert in the art that the angle can be variously changed according to the position of the fixing groove 163 is only a design change within the protection scope of the present invention.

The stopper member 164 is installed on the door 120, and serves to allow the opening angle of the door 120 to be stopped and fixed at 0 °, 45 ° and 90 °, respectively, as described above. That is, the stopper member 164 is installed in the fixing groove 163 of the fixing plate 162 so as to be coupled and separated. In more detail, the stopper member 164 includes a recess 164a and a fixed shaft 164b. That is, the stopper member 164 is formed with a groove 164a having a predetermined depth in the door 120, and the groove 164a is provided with a fixed shaft 164b coupled to move up and down. Of course, the upper end of the fixing shaft 164b is coupled to and detachable from the fixing groove 163 of the fixing plate 162. Furthermore, a spring 164c may be further interposed in the fixing shaft 164b as the groove 164a to move the fixing shaft 164b up and down elastically. The portion indicated by hatching in the drawing means the current position of the fixed shaft 164b of the stopper member 164. In the figure, the door 120 is in a sealed state, that is, a state of 0 °.

On the other hand, on the surface of the outer door 120 of the groove 164a, a separation prevention plate 165 may be further installed to prevent the fixed shaft 164b from being separated outward.

3A and 3B are partial sectional sectional views showing an operating state of the opening angle stop device of the door for a closed mechanism according to the present invention. Referring to the drawings, the operation state of the present invention will be described. In this case, the user opens the refrigerating compartment door 120 of the refrigerator as an example.

First, when the user pulls the handle 123 of the door 120 in the outward direction, the door 120 is opened at an angle about the rotation shaft 161. At this time, the fixed shaft 164b mounted on the stopper member 164 slides along the surface of the fixed plate 162. Of course, at this time, each time the fixed shaft 164b passes through the fixing groove 163 of the fixing plate 162, a certain sound may be generated, and by this sound, the user fixes the fixing shaft 164b of the fixing plate 162. It can be seen whether it is coupled to or separated from the groove 163.

For example, if the user releases the door 120 at an angle of approximately 45 ° as in FIG. 3A or at an angle of approximately 90 ° as in FIG. 3B, the opening of the door 120 stops exactly at that angle. In particular, if the time when the user stops opening the door 120 is coupled to the fixing groove 164 formed on the fixing plate 162, the fixing shaft 164b mounted on the stopper member 164, the door 120 of the refrigerator ) Doesn't move until you apply some force. In the figure, the fixed shaft 164b is indicated by hatching.

Furthermore, the spring 164c is coupled to the lower portion of the fixing shaft 164b of the stopper member 164, so that the fixing shaft 164b is fixed to the fixing plate 162 by elastic force of the spring 164c. It is in a state of being strongly pushed toward the groove 163. Thus, the opening angle of the door 120 is stopped and maintained even more stably.

Therefore, the door 120 does not open or close itself by its own weight, and the door 120 does not open or close even if it is not installed horizontally.

Of course, when the user applies the external force to the door 120 to close the door 120 or move at a different opening angle, the fixed shaft 164b of the stopper member 164 compresses the spring 164c and at the same time, the fixed plate By sliding with the surface of 162, the door 120 is moved as desired by the user.

In addition, although the stopper member 164 is shown as a spherical body integral with the tip portion, it is possible to reduce the frictional resistance during contact with the fixing plate 163 by incorporating a ball, such as with a ballpoint pen attached to the tip portion, such deformation Even if it is clear that the technical spirit of the present invention as it is, it does not depart from the protection scope of the present invention.

As described above, according to the present invention, the door is fixed by the stopper after the door of the sealing mechanism is opened at a predetermined angle, so that the door is not opened or closed by its own weight, thereby providing a convenient effect on use.

Moreover, even if the sealing mechanism is installed in a position where the sealing mechanism is not completely flat, the door is fixed without moving in an open state at an angle, so that the position of the sealing mechanism does not need to be exactly leveled.

What has been described above is only one embodiment for carrying out the opening angle stop device for the door for a closed mechanism according to the present invention, the present invention is not limited to the above-described embodiment, as claimed in the following claims As described above, any person having ordinary knowledge in the field of the present invention without departing from the gist of the present invention will have the technical spirit of the present invention to the extent that various modifications can be made.
