BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a drawer / refrigerator door of the present invention will be described below with reference to FIGS. 1 to 8.

(Embodiment 1) 2 is a refrigerator door, which is axially supported on the front surface of the refrigerator body 1 and is openably and closably mounted, and is composed of upper and lower door frame members 3, a door panel 4, and a heat insulating material 5. ing.

Reference numeral 6 denotes a handle having a horizontally extending grip portion 7 on the open side of the refrigerator door 2 so that the handle 6 can be moved back and forth when the refrigerator door 2 is opened.

First, a method of attaching the handle 6 of the refrigerator door of the present invention to the refrigerator door 2 side will be described.

A pin 9 protruding from the shaft plate 8 is inserted into a part of the handle 6, and one end of the pin 9 is inserted into an insertion hole portion 12 of a bearing plate 11 attached to the refrigerator door 2 side by a bearing plate attaching screw 10. The handle 6 is attached to the refrigerator door 2 side by inserting the shaft plate attaching screw 13.

Next, the opening / closing operation of the refrigerator door handle according to the present invention will be described. The handle 6 attached by the above-described method can be grasped from the three directions of the upper and lower sides and the non-fixed direction, and the refrigerator door 2 can be opened and closed. At that time, by using the pin 9 of the shaft plate 8 as a fulcrum 13 'and pulling the handle 6 toward the front, the other handle end portion 14' is moved to the outer case 1.
By pushing 4 the door opening force can be reduced.

With the above construction, the door can be grasped from three directions, that is, the upper and lower directions and the non-fixed direction, and it has an excellent degree of freedom in actual use. Further, the handle 6 is movable and the outer box 14 is pushed, whereby the door opening force is It is light and easy to clean.

Further, the repulsion member 15 is inserted into the pin 9 from the shaft plate 8 inside the handle 6, the end portion is brought into contact with the spring insertion hole 16 of the handle 6, and the other end is brought into contact with the shaft plate 8. This has the effect of returning the position of the handle 6 to the normal position after the door is opened.

In addition, the handle portion 6 which is frequently touched by hands is used in a refrigerator for storing food by subjecting the handle 6 to an antibacterial treatment by adding an antibacterial material.
It has the effect of maintaining cleanliness by antibacterial action.

Further, by providing the grip portion 7 of the handle 6 with a satin finish and providing the grip portion 7 with fine irregularities 17, there is the effect of eliminating the slipping of the hand when the door is opened and closed and improving the operability.

Next, 18 is a drawer refrigerator door,
It is composed of upper and lower drawer door frame members 19, a door panel 4 and a heat insulating material 5, and is attached to the front surface of the refrigerator body 1 so as to be drawn out. At the center of the drawer / refrigerator door 18, a handle portion 20, a horizontal pin insertion hole 21, a drawer handle 23 having a movable plate push pin 22, and a convex shape 2
4 and a movable plate cover 26 that covers the movable plate 25. The horizontal pin insertion hole 21 of the drawer handle 23 and the pin insertion hole 27 of the drawer door frame member 19,
By inserting the horizontal pin 28, the horizontal pin 28 is fulcrum 13 '.
As the pull-out handle 23 is pulled toward the front, the movable plate push pin 22 rotates, and the convex shape 24 of the movable plate 25 is pushed and moved, so that the end 28 ′ of the movable plate pushes the outer box 14. The door opening force can be reduced by utilizing the lever principle.

Further, a pull-out repulsive member 29 is inserted into the horizontal pin 28 inside the pull-out handle 23 so that the end portion is the convex shape 24 portion of the movable plate 25 and the other end portion is the pull-out door frame member 19. By bringing them into contact with each other, the position of the drawer handle 23 can be returned to the normal position after the door is opened and closed.

[0021]

As described above, the handle of the refrigerator door according to the present invention has the above-mentioned structure so that the handle is movably attached, and when the refrigerator door is opened, the handle is actuated and pushes the outer box, so that the door opening force is increased. It is possible to provide a drawer / refrigerator door that is light and has good operability.
