Description

[Detailed Description of the Invention] The present invention relates to a device for opening doors from the inside of pans, containers, etc.

As shown in Fig. 1, the normal door locking structure for pans, containers, etc. is such that the doors 3, 3 are rotatably attached to the left and right pillars 2, 2 of the door frame 1 via hinges 20, 20, etc. A lock rod 4 is rotatably attached to the outer surface of the door 3, cams 5 are provided at the upper and lower ends of the lock rod 4, and one end of the handle 6 is attached to the lock rod 4 at the upper and lower ends. Rotatably pivoted, door 3
, 3 are closed, the lock rod 4 is rotated by operating the handle 6, and the upper and lower end cams 5, 5 are removably engaged with the cam holders 7, 7 fixed to the upper and lower parts of the door frame 1. The handle 6 is individually secured by a handle latch portion 8 in order to lock the door and hold it in this state.

To open the doors 3, 3, remove the handle 6 from the handle latch part 8, rotate the handle 6, and engage the cams 5, 5 provided at the upper and lower ends of the lock rod 4 with the cam holder 7.7. , and pulled the handle 6 toward you to release it.

Therefore, the door 3.3 can only be opened from the outside, and it goes without saying that an accident could occur if the door is locked without realizing that someone is inside the pan, container, etc., especially at low temperatures. Lives are at risk when transporting refrigerated pans, containers, etc.

In view of the above circumstances, the present invention fixed the handle 6 with the handle latch part 8 in order to keep the door 3 locked, but the bracket of the handle latch part 8 was rotated outward from the inside of the door. By moving the handle, the handle 6 and the handle latch part 8 are disengaged, thereby making it possible to open the door 3 from the inside of the pan, container, etc.

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

FIG. 1 shows a state in which the door of a pan, container, etc. is locked.

FIG. 2 shows a view taken along the line A--A in FIG. FIG. 3 shows a view taken along the line B--B in FIG. 2.

FIG. 4 shows a state in which the handle and the bracket are disengaged.

The handle latch part 8 consists of a latch 9 that prevents the handle 6 from rotating upward, a support member 10 that prevents the handle 6 from rotating downward, and a bracket 11 that prevents the handle 6 from moving outward. This bracket 11 is pivotally connected to a shaft 14 provided between support members 13 and 13 fixed to both side edges of the washer 12.

The latch 9 is rotatably mounted around a bolt 15 via a washer 12.

A projection 18 having an inclined surface 17 is provided at the outer end of a support shaft 16 that rotatably passes through the door 3 and the washer 12.
To prevent the bracket 11 from rotating on the inclined surface 17 of
The lower end is supported as shown in FIG.

The inner end of the support shaft 18 is bent to form a rotary arm 19.

With the above structure, if the door is accidentally locked from the outside without noticing that someone is inside the pan or container, rotating the rotary arm from the inside will cause the protrusion 18 to rotate. The inclined surface 17 no longer supports the lower end of the bracket 11 and rotates outward as shown by the chain line in FIG. 2 and FIG. 4, the handle 6 moves outward, and the lock rod 4 By rotating, the cam 5 and the cam holder 7 are disengaged, and the door 3 can be opened from the inside.
