STORAGE HOUSE
Document Type and Number:
Japanese Patent JP2020024050
Kind Code:
A
Abstract:
To provide a storage house equipped with a door opening structure which requires the small total costs as compared with a conventional door opening structure, and can largely open a door to a half-opening position suitable for taking in/out food products.SOLUTION: A door opening structure is composed of a motor 20, a driving arm 21, a door opening lever 22, a start switch 23, and a control portion 24. The door opening lever 22 is rockably supported by a case body 1 between an operation stand-by posture and a kick-out posture. When the start switch 23 is turned on, the control portion 24 stars the motor 20 to rotation-drive the driving arm 21, and the rotating operation is transmitted to the door opening lever 22 by a transmission body 54 and a delay spring 55. During a half rotation of the driving arm 21, the door opening lever 22 is received by a receiving portion 25 of a door 3, so that the delay spring 55 gradually accumulates power. The spring force of the delay spring 55 exceeds magnetic absorbing force of a door packing 18, the door opening lever 22 is rapidly switched to the kick-out posture to forcibly open the door 3 toward a half-opening position.SELECTED DRAWING: Figure 1
