Description

A semiautomatic hanger-type interlocking three door}

The present invention relates to a semi-automatic hanger-type three-linked door, and more particularly, the first to third doors are suspended and linked to the guide rail frame body of the upper door frame, and the door is manufactured and installed to be fixed to the guide rail frame body of the door. The work is done quickly and firmly, and the door opening and closing operation is smooth and noiseless in that it prevents shaking in the forward and backward direction applied to the door, such as wind pressure, by the stable support of the upper and lower parts according to the sliding movement of the door. The present invention relates to a semi-automatic hanger-type three-interlock door that can have reliability and automatically closes when a door is opened by installing a door closer on a door frame to enhance user convenience.

In general, compared to a two-door structure, because of the advantage of being able to use a wider entrance, three doors are interlocked by a sliding method, that is, the second and third doors are interlocked in succession by the opening and closing operation of the first door, so that the first and second doors are Three interlocking doors that open and close have been conventionally used.

The operation principle of such a three-interlocked door is that the first door and the third door are connected to a belt wound around a pulley installed on both sides of the upper second door in the middle by a connecting member, and the third door is installed in a state in which the movement is fixed, When opening and closing the first door, the second door is moved to the side of the third door to be opened or moved to the side of the first door in conjunction with the first door to be closed.

Patent Literature 1 to Patent Literature 4 have been disclosed as examples of technologies related to these three interlocking doors.

Patent Document 1 discloses a case where the thickness of the first door, the second door, and the third door is different, or the gap between the first door, the second door, and the third door ( Opening and closing that can be used even when the thickness or gap is different in order to solve the problem of having to make and exchange the transmission body or interlocking body for doors separately, that is, the transmission body or interlocking body for door cannot be used in common when the interlocking body for door is different. A sieve interlock has been proposed.

However, Patent Document 1 has a problem in that noise is generated by the sliding part when opening and closing the door body, and a problem in that noise is generated by the sliding hole part for common use with door bodies of different thicknesses, and the door interlocking device There is a problem in that the configuration of the complex increases the production cost and manufacturing cost.

Patent Document 2 forms a continuous gear portion on the outer surface of the traction belt installed in a closed loop through pulleys installed at both ends of the second door, and racks on the first door and the second door in correspondence with the gear portion ) is installed so that the traction belt is moved by the engagement of the gear unit and the rack to interlock each door, or the guide roller assembled on the upper part of the first to third doors, which are heavy chains, is attached to each groove of the upper rail. By sliding the lower rail by the roller in the positioned state, the guide roller on the upper part simply has a function of slide movement, so the weight is concentrated on the lower rail and the roller by each door, which is a weight according to long-term use, so that the roller There is a disadvantage of increased noise generation due to abrasion and a short service life.

Patent Document 3 maintains the movement of each door stably by minimizing the clearance tolerance in which each door moves on the upper rail when the middle door, the front door, and the rear door move in the longitudinal direction of the upper rail, respectively. Interlocking devices for three interlocking doors have been proposed to prevent the generation of noise as much as possible, but each door, which is a heavy chain, has the disadvantage of concentrating on the lower rail. The disadvantages of the same noise and shaking as in Patent Documents 1 and 2 due to long-term use due to long-term use because it is not a structure that can prevent it, and the disadvantage of the short life of the lower roller due to the pressing of the heavy chain door remain.

Patent Document 4 is a semi-automatic interlocking door system, in which the door can be freely separated from the door frame without any structural change, and the door is configured to receive only horizontal movement force from the door interlocking device to open the door. A semi-automatic interlocking door system with a new structure that can be opened and closed with very light force has been proposed, but the slide movement is guided with each roller inserted into the rail groove of the upper guide panel, so that the support according to the sliding movement of the heavy body door is reduced. There is a disadvantage in that weight is concentrated on the lower rail and noise is generated, as well as vibration caused by gap noise between the roller provided on the upper part of the first to third doors and the rail groove of the upper guide panel due to long-term use.
