DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-caster type door, wherein one side in a frontage direction at an opening of a gate or a building is rotatably supported by a vertical surface (a portal or a wall) of the opening. The present invention relates to a device that is mounted with the other side protruding inside the opening frontage.

[0002]

2. Description of the Related Art A door having a large size, for example, in the direction of the frontage of a gate, such as a folding door, has a large load applied to a vertical rail on the hanging side. The load on the vertical rail on the suspension side and the load on the hinge supporting the door are reduced. However, if the approach portion of the base surface on which the gate is disposed is finished with unevenness using various tile materials, block materials, or the like, the resistance applied to the casters increases, and the door cannot be opened and closed smoothly.

[0003] Therefore, when the casters are removed, the door is easily broken by its own weight, and the durability of the door is remarkably reduced. In particular, the joint between the vertical bar and the horizontal bar on the door, the hinge supporting the door, and the hanging-side vertical bar are easily damaged. 57-1
No.71096, No. 59-26198, No. 59
No. 47098 proposes a gate in which a butt plate is overlapped at an abutting portion of an end surface of a horizontal rail at the inner surface of a vertical rail on a suspension side to reinforce a joint between the vertical and horizontal rails. It is not sufficient for relatively large and heavy doors that are large in the direction of the frontage and that are attached to gates or building openings.

[0004]

SUMMARY OF THE INVENTION The present invention provides a door that is large and heavy in the direction of the frontage of an opening in a gate or a building, and is sturdy and hard to break. As a result, a caster is not required. Another object is to provide a durable door.

[0005]

SUMMARY OF THE INVENTION The present invention relates to a door that is hung on a vertical surface of an opening and that projects toward the frontage of the opening. The door has a door frame body in which a hanging-side vertical rail, a door stop-side vertical rail opposed thereto and upper and lower horizontal rails are assembled in a square shape. In the door frame, the hanging side vertical rail and the upper and lower horizontal rails abut the end face of the horizontal rail on the inner wall of the frame of the hanging side vertical rail, and reinforce the inner surface of the inner circumferential side wall of the hanging side vertical rail. The backing plate is polymerized and fixed.

The reinforcing plate has a first reinforcing rib elongated in the up-down direction with the flat plate portion, a second reinforcing rib in a direction substantially intersecting with the first reinforcing rib, and an annular third reinforcing rib .

[0007]

The reinforcing backing plate reinforces the connection between the hanging side vertical rail and the upper and lower horizontal rails of the door frame, and suppresses the deformation of the connecting part. The first reinforcing rib and the third reinforcing rib in the reinforcing patch plate suppress the bending of the hanging side vertical rail in the door frame body in the vertical direction. The second reinforcing rib and the third reinforcing rib in the reinforcing patch plate suppress the bending of the hanging side vertical rail in the door frame in the width direction (inside and outside of the opening).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 and 2, a gate 1 is a folding door 4 on which a hanging door 2 and a door stop 3 are pivotally attached so as to be freely foldable.
And an opening / closing door 8 and a gate post 7. The frontage between the gate posts 7 is an opening with the facing surface of the gate post 7 as an upright surface. In the folding door 4, the hanging side vertical bar 5 of the hanging door 2 is hinged to one of the gate posts 7 via a hinge 6 so as to be openable and closable. The opening / closing door 8 is a single piece, and is attached to the other gate post 7 '. Note that no casters are attached to the lower ends of the folding door 4 and the opening / closing door 8.

The hanging door 2 of the folding door 4 has a hanging side vertical bar 5 having a hollow cross section and a door stop side vertical bar 9 opposed thereto.
A shielding plate 12 is attached to the inner periphery of a door frame 2A in which upper and lower horizontal rails 10 and 11 are assembled in a square shape, and the hanging side vertical rail 5 is a door stop side vertical rail 9 and horizontal rails 10 and 11. It is formed to have a higher wall thickness.

Fitting pieces 13a, 13b are provided at both ends of the facing surfaces of the hanging-side vertical rail 5 and the door stop-side vertical rail 9 in the expected direction toward the inner periphery, and both ends of the horizontal rails 10, 11 are fitted. Piece 13a,
13b. Further, in the inner circumference of the hanging side vertical rail 5 and the door stop side vertical rail 9, the reinforcing abutment plate 14 is superimposed on the inner surface of the frame inner peripheral side wall 2 a with which the end faces of the horizontal rails 10 and 11 abut. As shown in the figure, the end faces of the horizontal rails 10 and 11, the side walls of the hanging side vertical rail 5 and the door stop side vertical rail 9 and the reinforcing plate 14 are joined by a fixing tool 15 such as a tapping screw.

The door stop door 3 of the folding door 4 has a door frame 3A in which a hanging side vertical bar 16, a door stop side vertical bar 17, and upper and lower horizontal bars 18, 19 each having a hollow cross section are assembled in a square shape.
A shield plate 12 ′ is attached to the inner periphery of the door, and its hanging side vertical rail 16 and the door stop side vertical rail 9 of the hanging door 2 are folded hinge 31.
It is pivotally attached by a foldable. A door stop 20 which comes into contact with the door stop side vertical bar 17 ′ of the door 8 when the gate 1 is closed is attached to the door stop side vertical bar 17 along the height direction. A lock device 21 that detachably engages with the contact side vertical bar 17 ′ is provided, and a handle 22 for operating the lock device 21 is provided.

Further, similarly to the hanging door 2, fitting pieces 13 a and 13 b are respectively provided at opposite ends of the facing surface of the hanging side vertical bar 16 and the door stopping side vertical bar 17 of the door stop door 3 in the expected direction. 3
, And both ends of the horizontal rails 18 and 19 are fitted between the fitting pieces 13a and 13b. Further, on the inner circumference of the hanging side vertical rail 16 and the door stop side vertical rail 17, the reinforcing abutment plate 14 is superimposed on the inner surface of the frame inner peripheral side wall 3 a with which the end faces of the horizontal rails 18 and 19 abut. End faces of 18, 19,
The side walls of the hanging-side vertical rail 16 and the door stop-side vertical rail 17 are joined to the reinforcing pad 14 by a fixing tool 15 such as a tapping screw.

The reinforcing abutment plate 14 is slightly narrower than the expected inner surface width of each of the vertical bars 5, 9, 16, 17 of the hanging door 2 and the door stop door 3, and the vertical dimensions of the horizontal bars 10, 11, 18, 19. It has a slightly larger band-shaped flat plate portion 23. In the flat plate portion 23,
As shown in FIGS. 4 to 6, first reinforcing ribs 24 along the vertical direction are formed on both side edges thereof by being bent to one surface side,
A second reinforcing rib 25 extending in the expected direction is formed near the upper and lower ends so as to protrude toward one surface side, and an annular third reinforcing rib 26 is formed at an intermediate portion by punching out toward one surface side. Further, a pair of left and right fixture insertion holes 27 are formed at both ends of the flat plate portion 23.

The hinge 6 is composed of an arm 29 and a spindle tube 30, and both are made of stainless steel, which has higher strength than a zinc alloy cast iron die-cast product which is a conventional general material. As shown in FIG. 1, the arm 29 is attached to the inside of the hollow case 28 attached to the upper and lower portions of the inner wall surface of the opening of the gate post 7 so that the position can be adjusted in the inside and outside directions and the frontage direction of the opening. A hinge shaft 6a is provided upright at the tip. The support tube 30 is protruded from the hanging side vertical bar 5 of the hanging door 2 in the direction of the gate post 7, and is rotatably fitted to the hinge shaft 6a. Thus, the hanging door 2 of the folding door 4 is supported on the gate post 7 so as to be freely opened and closed.

The structure and mounting structure of the opening / closing door 8 are substantially the same as those of the hanging door 2, but the door stop side vertical bar 17 'of the folding door 4 is in contact with the door stop side vertical bar 17 of the folding door 4. Is mounted along the height direction, and another lock device 21 ′ is provided which is detachably engaged with the lock device 21 of the door stop side vertical rail 17 of the folding door 4. If the weight of the opening / closing door 8 is light, it is not necessary to increase the thickness of the hanging-side vertical rail 5 '. In some cases, a folding door may be attached to the other gate post 7 'in place of the single door 8.

With the above construction, the folding door 4 is not provided with a caster for supporting its own weight, so that the own weight of the folding door 4 having a large width in the frontage direction is all with respect to the hanging side vertical rail 5 of the hanging door 2. It becomes a load, and also becomes a load on the hinge 6. However, the hanging side vertical rail 5 of the hanging door 2 is made thick and strong, and can withstand this load. Further, since the hinge 6 is made of stainless steel having higher strength than a normal hinge, the hinge 6 can sufficiently support its own weight.

Further, the vertical rail 5 and the horizontal rail 1 on the hanging side of the hanging door 2
A load is applied between 0 and 11 by its own weight so as to cause the inner peripheral surface of the hanging-side vertical bar 5 to bend in the vertical direction. The first reinforcing ribs 24 and the annular third reinforcing ribs 26 of the reinforcing plate 14 used by being superimposed on the inner surface of the bar 5 are received by the connecting portions between the horizontal bars 10 and 11 and the hanging-side vertical bar 5. In the vertical direction is suppressed. When the folding door 4 is opened and closed, the suspension side vertical rail 5 and the horizontal rail 1
Between 0 and 11, there may be a large load acting to curve the inner peripheral surface of the hanging-side vertical rail 5 in the width direction. This load is applied to the second reinforcing rib 25 of the reinforcing patch plate 14 and the second reinforcing rib 25. 3
And the bending of the suspension-side vertical rail 5 in this direction is suppressed.

The ridge-shaped second reinforcing ribs 25 are not exactly arranged in the expected direction (the width direction of the flat plate portion), but are formed to be slightly inclined and substantially intersect with the first reinforcing ribs 24. May be. The effect of suppressing bending is the same in the hanging-side vertical rail 16 of the door stop door 3.
As a result, the folding door 4 of the gate 1 can withstand long-term use without being broken without the casters. Note that the vertical rails 5 that form the door frame of the hanging door 2
9. If the materials and wall thickness of the horizontal rails 10 and 11 are sufficiently strong and the hinge 6 is a sufficiently strong door,
The durability of the gate 1 can be improved only by providing the reinforcing pad 14 and having the effect of suppressing bending.

The above is an embodiment, and the present invention is not limited to the illustrated specific configuration. The thickness of the hanging-side vertical rail 5 of the hanging door 2 depends on the weight of the folding door 4. In addition, the wall thickness of the hanging side vertical rail 16 of the door stop door 3 may be increased. Although the description has been made centering on the folding door 4 of the gate 1, the present invention is basically applicable to a single door having a large overhanging dimension from the elevation of the opening toward the frontage of the opening. . Such a door is not limited to a gate and includes a door for opening and closing an opening of a building. The gate can be a single door with a single door.

[0020]

According to the first aspect of the present invention, the first, second, and second reinforcing plates at the connecting portion between the hanging-side vertical beam and the horizontal beam are provided .
The reinforcing ribs of No. 3 support the weight of the door, suppressing the vertical bending and the widthwise bending of the hanging-side vertical rail, and increasing the strength at the joint between the hanging-side vertical rail and the horizontal rail. The durability is improved. Further, there is no need to support the lower end of the door with casters, and the door can be smoothly opened and closed at all times regardless of the state of the base surface on which the gate is mounted.
