Description

Crack finishing unit for folding door "

The present invention relates to a gap finishing hole for preventing a gap between a door frame of upper and lower guide rails and door frames of a unit door constituting a folding door.

BACKGROUND OF THE INVENTION [0002] Generally, a folding door system is a type of door system that expands the open feeling and the field of view by providing a wide open area compared to a conventional rotary or sliding door, It is mainly used in commercial buildings for restaurants and the like considering space openness.

A typical folding door system includes a plurality of unit doors 10, a roller mechanism 20 for supporting the unit doors 10, and a hinge 22 for foldably connecting the unit doors 10, as shown in FIG.

Each unit door 10 includes a glass panel 12 and a door frame 14 that surrounds the outer edges of the glass panel 12. The roller mechanism 20 includes a door frame 14 And the hinge 22 is configured to connect between the door frames 14.

The upper guide rail 5 and the lower guide rail 5 '(the lower guide rail is buried under the floor and are indicated by dotted lines in the figure) are provided at the upper and lower ends of the portion forming the doorway of the building, Is linearly moved along the upper guide rail 5 and the lower guide rail 5 '.

The folding door according to the related art is opened and closed while the unit doors 10 are rotated and folded together while being conveyed along the upper and lower guide rails 5 and 5 'by the roller mechanism 20.

In the conventional folding door, there is a gap between the unit door 10 and the upper and lower guide rails 5 and 5 'due to the rotating folded structure of each unit door 10, A slight gap is formed between the door frames. As a result, the indoor air and the outside air communicate with each other through this gap, so that the heating efficiency is lowered in the winter and the cooling efficiency is lowered in the summer.

Therefore, the upper and lower ends of the door frame 14 of each unit door 10 are provided with the mohair 15 to block the gap between the door frame 14 and the upper and lower guide rails 5 and 5 ' A gap is blocked between the door frames 14 of the unit doors 10 by using a flexible strap (also called a wader strap) (not shown).

However, since the upper and lower hinges 22 attached to the door frame 14 of each unit door 10 are referred to as the upper and lower hinges 22, the blocking strap is not attached to the upper and lower portions of the upper and lower hinges 22, The gap remains between the door frame 14 of the first embodiment.

Therefore, according to the related art, there is a problem that the outside air flows into the room unnecessarily through the gap without the mohair 15, or the room air flows out to the outside.

The present invention has been conceived to solve the above problems of the prior art and it is an object of the present invention to provide a folding door which is capable of preventing a gap between door frames of a unit door and a gap between a door frame and a guide rail from being unnecessarily ventilated And to provide a gap finish for a folding door.

According to an aspect of the present invention, there is provided a gap finishing tool for a folding door, including: a vertical molding part having a block shape; a horizontal molding part having a block shape perpendicular to the vertical molding part; And a horizontal insert part provided on one side of the horizontal molding part.

Both side surfaces of the vertical insert portion and the horizontal insert portion are formed symmetrically with respect to each other, and a wedge jaw portion engaged with the engagement jaw inside the door frame of the unit door is formed.

As described above, according to the present invention, when the folding door is closed, the gap between the door frames of the unit door and the gap between the door frame and the guide rail are tightly blocked.

Accordingly, there is an advantage that the phenomenon that the cooling efficiency or the heating efficiency is lowered by the phenomenon that the indoor and outdoor are unnecessarily ventilated in the closed state of the folding door is positively prevented.

Hereinafter, specific details for implementing the present invention will be described in detail with reference to FIGS. 2 to 8 attached hereto.

As shown in FIG. 2, the gap finishing tool 30 for a folding door according to one embodiment of the present invention includes a block-shaped vertical molding part 32 and a horizontal A vertical insert part 34 provided on one side surface of the vertical molding part 32 and a horizontal insert part 35 provided on one side surface of the horizontal molding part 33.

On both sides of the vertical insert part 34 and the horizontal insert part 35, wedge jaws 341 and 351 formed in symmetrical directions are formed, respectively.

The vertical molding part 32 and the horizontal molding part 33 may be formed in various shapes. For example, the vertical molding part 32 and the horizontal molding part 33 may be formed in a hexahedron shape such as a square block .

3, the gap finishing tool 30 for a folding door according to an embodiment of the present invention as described above is configured such that the vertical insert portion 34 is formed on the vertical surface of the door frame 14 of the unit door 10 And the horizontal insert portions 35 are fitted to the upper and lower edges of the door frame 14 in such a manner that the horizontal insert portions 35 are fitted to the horizontal surfaces of the door frames 14 of the unit doors 10, respectively.

4, when the gap finishing tool 30 for the folding door is mounted on the door frame 14, the vertical molding part 32 covers the outer side of the vertical side of the edge of the door frame 14 And the horizontal molding part 33 surrounds the horizontal outer edge of the corner of the door frame 14. [

Therefore, according to the present invention, when the folding door is closed, the vertical molding part 32 is disposed in the gap between the door frames 14 of the unit doors adjacent to each other, thereby closing the gap between the door frames 14.

The horizontal molding part 33 blocks the gap between the door frame 14 and the upper guide rail 5 and the gap between the door frame 14 and the lower guide rail 5 '.

5, the wedge jaws formed on the horizontal insert part 35 and the vertical insert part 34 are caught by the engagement protrusions 141 on the inner side of the door frame 14, (Not shown).

Therefore, according to the present invention, the gap between the door frame 14 of the unit door and the door frame 14 or the gap between the door frame 14 of the unit door and the guide rails 5, 5 ' So that the phenomenon that indoor and outdoor are unnecessarily vented does not occur.

The gap finishing tool 40 or 40 'according to another embodiment of the present invention includes a vertical molding part 42' and a horizontal molding part 43 'perpendicular to the vertical molding part 42' A vertical insert part 44 'and a vertical insert part 44' provided on one side of the vertical molding parts 42 and 42 'and a side surface 43' of the horizontal molding parts 43 and 43 ' And horizontal insertion portions 45 and 45 'provided in the horizontal insertion portion (see FIG. 6).

The horizontal molding parts 43 and 43 'are formed in the shape of a hexahedron such as a square block, and only the vertical molding parts 42 and 42' are inclined at one side so that the cross- . &Lt; / RTI >

The vertical molding portions 42 and 42 'of the gap end portions 40 and 40' disposed adjacent to each other are formed such that the inclined shapes thereof are symmetrical to each other, so that when the folding door is closed, 40) 40 'are in surface-to-surface contact with the sloping surfaces of the vertical molding parts 42, 42'.

In another embodiment of the present invention, a pair of gap finishes 40 and 40 'adjacent to each other are opposite in the oblique direction of the vertical molding portions 42 and 42', and the other shapes are the same.

Therefore, according to another embodiment of the present invention, as shown in FIGS. 7 and 8, when the folding door is opened or closed, the vertical molding part 42 ) 42 'do not interfere with each other
