The upper claw shaft 12 is connected to the f section connecting rod 8.
' are respectively linked to the lower claw shafts 12' via the intermediate link 9, and a spring 1] is stretched downward from the lower link 8'.
Rotate the operating disk 6 into the handle 4 to open the upper and lower claw shafts 12, 12.
``(r) An operating bin 17 is provided for pulling the device into the interior,
A claw shaft locking mechanism 24 is provided in the frame facing the intermediate connecting rod 9, and a shaft piece 18 with a roller is provided protruding from the back side, and the hollow long frame 31
A long inner frame 33 with an arbitrary number of bolts 32 protruding from one side of the door body 30 is formed. Receptacles 34 with which the upper claw shaft 12 engages are provided protrudingly on both sides of the upper front end of the body 1, and receivers 34' with which the lower claw shaft 12' engages are protruded from both sides of the lower front end. Interior long frame 33.3
The plate piece 35.35'i is designed to be stabbed at the front end position of both sides of the box 1 with which the roller-equipped shaft piece 18 protruding from the back surface of the plate 35.35'i comes into contact.

Next, the effects of the present invention will be explained with reference to embodiment figures.

The double door device of the first embodiment shown in FIGS.
5.25', and when opening to the right using the handle 4 on the right side, hold the handle 4 and operation pin 17 and pull the operation pin 17 upwards, and it will slide. The plate 14 rises, and the engaging member 13 of the sliding plate 14 raises the pin 7' on the right side of the actuating disk 6, while the actuating disk 6 rotates counterclockwise, and the claw shafts 12, 12 at the upper and lower ends rotate. ' is disengaged from the upper pawl hole 27 and the lower pawl receiver 28, and the hollow door body 2 has the upper and lower pawls 1M+12 of the left pawl shaft mechanism 25'.

The opening is centered at 12'. When the operating disc 6 rotates counterclockwise, the lower connecting rod 8' and the intermediate connecting rod 9,
9' rises while resisting the elasticity of the spring 11, and the model protrusion 23 protruding from the intermediate link 9 presses the locking piece 21 of the pawl shaft locking mechanism 24 to a position above the lower position of the locking piece 21. The model protrusion 23 is locked on the upper surface of the locking piece 21, and the return elasticity of the spring 11 prevents the intermediate link 9 from descending, thus preventing the operating disc 6 from rotating in the opposite direction. This locks the reverse operation of the upper and lower pawl shafts 12, 12'. When the hollow door body 2 opened to the right is closed again, the roller-equipped shaft piece 18 protruding toward the back of the claw shaft locking mechanism 24 comes into contact with the front edge of the case 1 and is pressed. The long plate 19 and the locking piece 21 protruding from the roller shaft piece 18 slide against the elasticity of the spring 22,
The lock by the locking piece 21 of the model projection 23 is released, and the return elasticity of the spring 11 is acting downward on the lower connecting rod 8'1. The intermediate connecting rods 9 and 9' operate downward, the operating disc 6 simultaneously rotates clockwise while being pulled by the lower connecting rod 8', and the upper connecting lever 8 operates upward, and the two-jaw shafts 12 and 12 ' is a member that slides vertically and engages with the opposing upper claw hole 27 and lower claw receiver 28. Also, the left handle 4'
When opening to the left with
The hollow door body 2 is opened centering on the upper and lower pawl shafts 12, 12''!z of the right pawl shaft mechanism 25, and the hollow door body 2 can be easily opened in both directions.

11 to 16 show a double door device according to the second embodiment. After removing the handle and hinge for single opening of the hollow door body 30 of a ready-made refrigerator, the double door device is shown as in the second embodiment. A long internal claw shaft frame 33.33'' containing a claw shaft mechanism is attached to both sides of the hollow door body 30 with bolts 32 protruding from the sides, and is vertically opposed to the long internal claw shaft frame 33.33'. The upper claw shaft 12 is fitted to both sides of the upper front end of the box 29, and the lower claw shaft 12' is fitted to both sides of the lower front end of the case 29. , 34' are provided protrudingly, and plate pieces 35, 35' that press the roller-attached shaft piece 18 protruding from the rear side of the inner long frame 33, 33' of the claw shaft are attached to the front ends of both sides of the case 29. In the double-opening device of the second embodiment, the handle 4 of the right pawl shaft interior elongated frame 33 and the operating pin 17 are held together to open the hollow door body 30 in both directions. 17 upward, the internal actuating disk 6 rotates counterclockwise and the upper and lower pawl shafts 12.12
' is disengaged from the receiving metal fittings 34, 34', and opens to the right around the upper and lower claw shafts 12, 12' of the left claw shaft internal long frame 33', and the disengaged upper and lower claw shafts 12, 12 ' is held by the pawl shaft locking mechanism 24, and when the hollow door body 30 is closed, the roller-equipped shaft piece 18 is pushed by the plate piece 35 and the pawl shaft locking mechanism 24 is released, and the upper and lower pawl shafts 12, 12' are held by the spring. The operating disk 6 rotates clockwise due to the return elasticity of 11, and slides again to release the receiving bracket 34.3.
4'. Left side claw shaft inner long frame 33'
Similarly, the handle 4 can be used to open the door to the left.

As mentioned above, in the present invention, a left and right claw shaft mechanism is provided inside the door of a refrigerator or other face piece so that it can be opened both left and right, and a ready-made door body is improved so that it can be opened both left and right. This improves convenience when opening and closing the door body, and the structure of the pawl shaft mechanism is simple, and the door body can be opened in both directions efficiently without any malfunction. It has various remarkable effects.
