Description

Electric folding door system

The present invention relates to an electric folding door system, and more particularly, to an electric folding door system that allows a plurality of individual doors fastened to the drive screw installed inside the upper and lower guide rails to be stably opened and closed without tilting or twisting.

Generally speaking, the folding door is a folding door, which can be used as a replacement for the inner and outer walls of a building wall, and its durability is guaranteed in response to mechanical external force. Do.

In addition, the glass can be applied to the product to secure the field of view and its excellent design makes it an excellent folding door for interior use.

Such folding doors open more than 90% of the existing doors by more than 90% of existing doors in order to make valuable use of the space. It is a trend that is used as a doorway for houses and shopping malls.

The folding door is designed to open the door completely in a place where there is no space for opening the door completely outside the doorway of the wall, and constitutes an outer frame according to the shape of the door, and allows a plurality of single individual doors to be rotated with each other. It is coupled by a hinge hinge and hinged so that one end thereof rotates to one side of the doorway, the door is opened and closed while folding or folding the folding door composed of the connection of these individual doors in the direction of the doorway.

At this time, a groove-shaped guide rail horizontally installed on the outer surface and the bottom surface is formed on the outer frame forming the doorway, each of the individual doors are installed on the guide rail so that it can be moved to the left and right along Each of the upper and lower portions has a structure in which a movement guide roller including a roller positioned on a guide rail is formed.

However, such a conventional folding door structure has a disadvantage in that the user must push the side to one side while manually folding the individual doors manually.

In addition, the individual doors installed on the guide rails are spaced apart from the guide rails at a predetermined interval, so that there is a problem in that dust or foreign matters are introduced into the gaps without being completely soundproofed and windproof.

In addition, when the individual doors move along the guide rails, there is a problem that noise is generated by shaking left and right, and the individual doors are opened and closed by the user's power, so the opening and closing speeds of the individual doors are not constant. There was a problem that costs a lot.

The present invention was developed to solve various problems as follows. The purpose of the present invention is to stably open and close individual doors by moving the transfer gear to the left and right through a drive screw installed in the upper and lower guide rails without shaking. In order to provide an electric folding door system that blocks the tilting of the moving gear because the rotating shaft of the transfer gear is firmly supported to the upper and lower portions of the individual doors.

In order to achieve the above object, the present invention has a fixed frame consisting of upper and lower guide rails and left and right frames, and the upper and lower guide rails having an internal space, and fixed gears are installed at both ends. A rotating device including a drive screw, a power shaft connected to a motor to transfer power to the drive screw, and a gear having an insertion hole to penetrate the drive screw and exposed to the outside of the gear to be penetrated through the drive screw. It consists of a transfer gear formed with a fixture, a door portion consisting of a plurality of hinges that are installed to fold the individual door and the individual door fastened to the fixture of the transfer gear.

The present invention has various effects as follows.

First, there is an effect that the opening and closing of the individual door is stable by moving the transfer gear through the drive screw installed on the upper and lower guide rails.

Secondly, since the rotating shaft of the feed gear firmly supports the upper and lower surfaces of the individual gear, the individual door has the advantage of being stably made without shaking when folded.

A drive screw 20 having a fixed gear 21 and a rotating device 40 formed of a power shaft 41 connected to the motor 30 so as to transmit power to the drive screw 20, and a drive screw ( 20 and a transfer gear 50 having a gear body 52 having an insertion hole 51 and a fixture 53 fastened to an individual door while being exposed to the outside of the gear body 52 so as to penetrate therethrough. It is fastened to the fixture (53) of the) consists of a door portion 60 having an individual door 62 connected by a plurality of hinges (61).

The fixed frame 10 includes upper and lower guide rails 11 and 12 and left and right frames 15 and 16 fastened to both ends of the upper and lower guide rails 11 and 12.

The upper and lower guide rails 11 and 12 are formed in a rectangular bar shape having left and right openings while having a predetermined space therein, and fasten the closed cap 13 to both ends.

And in the center of the lower surface is formed a moving passage 14 in the longitudinal direction in which the fastener 53 of the transfer gear 50 can move.

The upper and lower guide rails 11 and 12 may be used by cutting their lengths as necessary.

The left and right frames (15) and (16) have a rectangular bar shape having internal spaces and fixedly install upper ends at both ends of the upper guide rails (11), and lower ends fixedly at both ends of the lower guide rails (12). do.

The rotating device 40 includes a drive screw 20 having fixed gears 21 fixed to both ends, and a power shaft 41 fastened vertically to one of the fixed gears 21 of the drive screw 20. And a motor 30 for transmitting power to the power shaft 41.

The drive screw 20 is a screw thread is formed on the outer surface and the fastener is formed on both ends. The fastener is fastened to the fastening hole of the stopper formed on the upper and lower guide rails.

In addition, fastening gears 21 are fastened to both ends of the drive screw 20.

As such, the drive screw 20 to which the fixing gear 21 is fastened is installed in the inner space of the upper and lower guide rails 11 and 12, and the fasteners of the drive screw 20 are upper and lower guide rails 11. It is fastened to the fastening hole of the stopper 13 formed in 12 to rotate.
