Description

Interlocking door moving equipment

The present invention relates to an interlocking door transfer device, and more particularly, when one door of a plurality of doors is opened and closed, the other door is interlocked to open and close. The present invention relates to an interlocking door conveying device that prevents flow, makes the coupling of the interlocking belt firm, and greatly improves the assembling and installation properties.

In general, windows or entrance gates installed in the living room, balcony, company, school, or hospital of an apartment are installed in the form of sliding doors to open and close in the horizontal direction, and individual doors are opened and closed by hand for indoor temperature control or ventilation. do.

The conventional door consists of a pair of two doors inside the door frame, and one of the doors is pushed toward the other door to open, or one door is pulled from the other door to block the opened door.

However, when the door is pushed open, only half of the door frame space is opened by the other door that is not pushed. Therefore, if the open space of the door frame is small and you want to pass items larger than the open space, you inevitably remove the door from the door frame. There is a problem in that after all are separated, the article must be passed and the separated door must be connected to the door frame again.

Accordingly, in recent years, a middle door interlocking door consisting of a plurality of doors, that is, a fixed door fixed to the door frame, an intermediate door connected to the fixed door, and an operation door connected to the intermediate door, has been installed.

Such a middle door interlocking door has an advantage in that it is possible to use the door widely because the open access space can be expanded compared to a conventional door composed of two doors.

In other words, when the operating door of the three doors is pushed toward the fixed door, the intermediate door slides in the same direction as the operating door and is superimposed on the fixed door by sliding movement of the operating door. All the doors are overlapped to expand the open space and widen it.

Looking at the prior art, a detachable direction changeable interlocking door transfer device, which is a registered patent No. 10-1943161, has been devised, which is a first in which both sides, upper and lower surfaces are bent in a'H' shape in cross section. A frame, a pair of wing plates each moving along both sides of the first frame, a pair of fasteners inserted into upper surfaces of both ends of the first frame and forming a rotating body, and the first frame A pair of first pivot connectors that are coupled to the lower surfaces of both ends of and have at least one first through hole into which the pivot of the interlocking door is inserted, and a belt that is wound around the rotating body and connected to the pair of wing plates. It consists of wealth.

This prior art is to be disassembled and assembled in a detachable manner when the direction of the door is changed during the installation of the interlocking door so that the installation can be easily changed and the production cost can be reduced by using the same frame.

However, in the case of the prior art, since the belt part is connected to the wing plate, when the user closes the door excessively in the process of opening or closing the door, the interlocking door is quickly opened from the fixed door, causing a problem that the belt part is removed from the wing plate. Has become.

In addition, as the rail connector is fitted to the frame of the door, noise is generated in the process of sliding the protrusion of the frame when opening and closing the door, as well as the rail when opening and closing the door as the frame protrusion and the rail connector are not firmly inserted. There is a problem in that the door shakes or rattles due to the shaking or flow of the connector.

Patent Document 1: Korean Patent Registration No. 10-1943161 (registered on January 22, 2019) Patent Document 2: Korean Patent Registration No. 10-1164439 (registered on July 4, 2012)

In the present invention, the operating door and the interlocking door are slid to the side of the fixed door fixed to the door frame, so that when the access space is opened or the access space is closed due to the distance from the fixed door, the door is prevented from shaking and rattled flow, and the sliding is facilitated. The purpose is to provide an interlocking door transfer device that can prevent noise generation in advance, and can prevent the interlocking belt from being separated and separated when the door is operated by firmly fixing the interlocking belt, and greatly improves assembly and installation properties. There is this.

As a means for achieving the above object, the interlocking door transfer device of the present invention is slidably moved along the longitudinal direction of the door frame frame to which the fixed rail is fixed to the door frame and the fixed door is connected, and the operating door is connected.

The first guide roller body, the second guide roller body, the first guide roller body and the second guide roller body are wound at both ends, and a plurality of belt engagement portions are provided along the longitudinal direction of the outer surface, and the interlocking belt is fitted and fixed to the fixed rail. A first rail linkage tool that slides along the longitudinal direction of the rail and includes a first door frame frame connection part and a first door frame frame guide part at the top, and a first sliding linkage linking one side of the linkage belt and the first rail linkage tool. It is inserted into the operating rail and slides along the longitudinal direction of the operating rail, and connects the second rail linkage port having a second door frame frame connection part and a second door frame frame guide part provided at the top, and the other side of the linkage belt and the second rail linkage tool. In the interlocking door transfer device consisting of a second sliding linkage, the first rail linkage is provided with a first connecting fitting, and the first sliding linkage extends to one side of the first sliding linkage, and the first A first connection part provided with a first fitting space part of a long hole to be fitted into the connection fitting hole; A first belt connecting portion provided on the other side of the first sliding linkage and having a first mating contact surface provided on the inner surface to which one side of the linking belt is inserted and inserted into the inner side of the linking belt; First elastic fastening portions respectively provided on both sides of the outer surface of the first belt connection portion; A first interlocking belt having a first elastic fastening protrusion that is elastically fastened to each of the first elastic fastening parts by covering the upper part of the first belt connecting part to prevent one side of the interlocking belt drawn into the inner surface of the first belt connecting part from being separated from the upper side. It consists of being provided with a departure prevention part.

In the present invention, a fixed rail is connected to a fixed door and an interlocking door is connected to a door frame frame, and an interlocking rail connected to one side of the fixed rail and an operating door are connected, and an operating rail is connected to one side of the interlocking rail. The interlocking rail slides in the same direction as the operating rail when opening and closing the access space by sliding toward the fixed rail side, thereby reducing noise when the interlocking rail and the operating rail slide in the left and right directions with respect to the door frame frame. It can be minimized, and one side of the interlocking belt wound on the interlocking rail is firmly connected and fixed to the fixed rail, and the other side of the interlocking belt is firmly connected and fixed to the operating rail, so that the fixed rail or the operating rail is separated and separated from the interlocking belt during sliding operation. In addition, the interlocking rail and the operating rail are easily and easily slid to the fixed rail side to open the access space, and the interlocking rail and the operating rail slide easily and easily from the fixed rail to close the access space. Therefore, the opening and closing action for the access space can be made smoothly and easily, so the usability and convenience are greatly improved.
