Abstract

The invention provides a door leaf opening and closing device which does not need a hinge to constrain the door leaf to make the door leaf move in a fixed manner, and can open the door leaf while pushing the door leaf out toward the front of the frame body. The door opening and closing device of the present invention has an opening and closing device main body 64 installed on the frame body 61, an installation part 65 installed on the door leaf 62, and is rotatably arranged on the opening and closing device main body 64, and the opening and closing device 62 is applied to the door leaf 62 by means of the installation part 65. The arm 66 for force in at least one of the closing directions, the slider 71 provided on the opening and closing device main body 64 so as to be slidable in one direction, the force adding units 72a to 72c for applying force to the slider 71 in one direction, Transmit the additional force of the additional force units 72a to 72c to the transmission mechanism 70 of the arm 66 and the door leaf constraint link 67; the door leaf constraint link 67 is rotatably coupled to the arm 66 and is coupled at At the same time, it is rotatably coupled to the mounting part 65 and slidably coupled to the opening and closing device main body 64 .

Description

technical field [0001] The present invention relates to a door opening and closing device that facilitates the opening and closing operation of a door (including a window; the same applies hereinafter). Background technique [0002] As a door opening and closing device that facilitates the opening and closing of the door, the applicant has proposed Figure 16 Shown door opening and closing device (referring to patent document 1). Such as Figure 16 As shown, the door leaf 2 is rotatably coupled to the frame body 1 via the hinge 3 around a horizontal axis. The closer the opening angle of the door leaf 2 is to 90 degrees, the greater the moment caused by the self-weight of the door leaf 2, and the greater the force required to open the door leaf 2. The door opening and closing device 4 generates a force for assisting the opening and closing of the door 2 in order to facilitate the manual opening and closing of the door. [0003] The door opening and closing device 4 includes...
