Abstract

The present invention relates to a rack hinge for mounting a hinge that the door is fixed in the middle position when the door is opened in the desired position among the products having a bottom up door, such as kimchi refrigerator.

In general, when opening and closing the bottom swing door, a hinge is attached to the end of the door, and most hinges are pressed by the force of a simple spring, so that a large amount of force is applied when the door is mounted on the door frame. It's easy to bring damage.

The present invention is designed to solve the existing inconveniences when opening and closing the door, to suppress the deformation of the door frame due to the strong spring force, and to maximize the point that can prevent the safety accident caused by the sudden change of the door. will be.

Description

Door hinge {DOOR HINGE}

The present invention relates to a hinge device that can rotate and open and close the flow member with respect to the fixed member, in particular to support the door to open and close the product of the bottom opening door can be useful when you want to stop the door in the middle Hinge device.

In particular, kimchi refrigerator is a product that is used by many housewives, the opening and closing operation of the door should be made smoothly. Kimchi refrigerators with bottom-up doors open and close the doors by their own weight due to the weight of the door.

When you open the door, you have to overcome the weight of the door, and when you close the door, the door descends at high speed due to its own weight.

Most housewives who use Kimchi refrigerator need to stop the door in the desired middle position because the door is taken out or put in with the door open in the middle to minimize the leakage of cold air.

For this reason, there is a problem to use as a hinge device of a simple structure that is common to appliances having a bottom up door.

The present invention, in view of the above, as well as the Kimchi Refrigerator as well as opening and closing the door of the product having a bottom opening door opening structure to open and close the desired angle to continue to work stably, the door is suddenly opened or closed The aim is to prevent accidents and to improve work efficiency.

It is still another object of the present invention to provide a hinge device that can stop the door in an intermediate open state, so that the device can be used more conveniently.

Fixing pin diagram for fixing the gear block of the hinge device according to an embodiment of the present invention, Figure 7 is sandwiched between the main body side hinge bracket and the door side hinge bracket assembly of the hinge device according to an embodiment of the present invention Figure shows the figure showing the slip ring.

1 and 2, the hinge device according to the present invention, the door side hinge bracket, the body side hinge bracket, gear block, spring, hinge hole shaft, gear block fixing pin, spring guide shaft do

The housing is formed by the main body side hinge bracket (1), the door side hinge bracket (6), the gear block 10 is assembled by Figs. 3, 4, 5 and 6, 7, It is not necessarily limited to.

According to the top view of FIG. 1, the main body side hinge bracket 1 is coupled by the hinge hole 2 by the door side hinge bracket 6 and the hinge hole shaft 8. In addition, when fixing to the main body of the body is fixed to the main body of the body using the wing hole (3) and the lower hole (4) of the hinge bracket (1) side. The door side hinge bracket 6 is fixed to the frame of the door by the hole 18 according to the guide hole 19. The spring 20 is held in position by the spring guide shaft 17 and maintains a constant elasticity. In addition, the spring 20 serves to push the gear block 10 with a constant force. The spring guide hole 5 is configured to move the spring guide shaft 17 having one end 13 fixed to the gear block 10.

As shown in the front view of FIG. 2, the door-side hinge bracket 6 rotates and rotates about the hinge hole shaft 8, and the gear 9 of the door-side hinge bracket is the gear 11 of the gear block 10. Contact with The door side hinge bracket 6 rotates about the hinge hole shaft 8, and engages with the gear 11 of the gear block 10 and slides in response to the movement of the door hinge hinge 6. Will have At this time, when the door-side bracket gear 9 crosses the gear 11 of the gear block 10, the gear block 10 is pushed backward by the height of the gear 11 and then the door-side hinge bracket gear ( When 9) slips and crosses the gear 11 mountain of the gear block 10, the gear block 10 is pushed up again by the force of the spring 20. The gear 11 of the gear block 10 is composed of a plurality of and the door side hinge Bracket gear 9 slides the gear 11 of the gear block 10, when the user opens the door, the door side hinge When the gear 9 of the bracket 6 is engaged between the gears 11 of the gear block 10, the spring 20 is configured to be stopped at an intermediate position by a force that the spring 20 pushes up. Therefore, the door can be stably stopped at an intermediate position, so that the user can increase convenience and prevent the user from being injured by the sudden change of the position of the door.

3 shows a plan view of the door side hinge brackets. According to this figure, the hinge hole shaft 8 is fitted into the hinge hole 2, and is fixed and mounted by the hole 3 and the hole 4 when it is mounted to the apparatus main body of the kimchi refrigerator.

One end of the spring guide shaft 17 is fixed to the hole 13 of the gear block 10 and is fitted into the hole 5 of the hinge bracket 1 of the main body.

4 shows a front view of the door side hinge bracket 6.

The door side hinge bracket 6 is assembled by being fitted into the hinge hole 2 of the main body side hinge bracket 1 by the hinge hole shaft 8. At this time, in order to minimize friction between the main body side hinge bracket (1) and the door side hinge bracket (1) and to soften when the door side hinge bracket (6) moves, the door ring hinge bracket (6) Assemble with the hinge brackets (1) on the main body by inserting them on both sides.

The gear 9 of the door-side hinge bracket 6 consists of only one gear mountain and its tip is slightly rounded so that it can slide smoothly while rubbing against the gear 11 of the gear block 10. .

5 shows a front view of the gear block 10.

The gear 11 of the gear block 10 includes a plurality of gears 11 as shown in FIG. 5, and the gear block 10 has a hinge block bracket on the main body by a gear block fixing pin 15 in the hole 14. 1), and after the washer 21 is inserted, the gear block 10 is finally fixed to the body-side hinge bracket 1 by the snap ring 22.

As described above, the hinge device according to the present invention is very useful because it can cope with the weight of the door by adjusting the elasticity of the spring when the gear of the door-side hinge bracket and the gear of the gear block are engaged. In addition, if the operation stops in the middle of the opening or closing of the door, the door stops in place. In other words, the opening degree of the door can be adjusted in several stages according to the number of gears of the gear block, and stable and fixed in the middle position without shaking, so that food can be easily taken out or stored in the open state.

In addition, the hinge device according to the present invention, even when the door is opened or closed, even when the hinge device of the same size exerts a great force according to the elasticity of the spring can be easily applied according to the weight of the door is very useful.

As described above, according to the present invention, it is possible to easily open and close the door of the device having not only a Kimchi refrigerator but also a upward swing door, so that the door opening and closing operation can be facilitated, thereby increasing the reliability and recognition of the product. have.

In addition, according to the present invention, since the intermediate stop of the door can be performed in several stages, the convenience of use can be achieved for all products having the upward swing door.

The kimchi refrigerator has been representatively described to illustrate the principle of the present invention, but the present invention is not limited to the configuration and operation as shown and described. Therefore, all appropriate changes, modifications, and equivalents should be considered to be within the scope of the present invention.
