Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door metal fitting attached to a lower end portion of a sliding door in a door roller type sliding door structure provided in an opening of a house.

[0002]

2. Description of the Related Art A door-sliding sliding door structure is provided with a sill, a sill, and a four-sided frame consisting of a pair of left and right vertical frames in the opening. It is provided so as to be openable and closable along the door roller rail fitted in the sill groove. The door metal fitting is fixed by using a screw or the like to a recess formed by digging a crosspiece at the lower end of the sliding door.

[0003]

The sliding door is used in a single pulling or sliding structure, and the frame or sliding doors pass each other to be sealed, and in order to improve the sealing property, the sliding clearance is required. Is provided so as to be as small as possible.

Therefore, when the sliding door itself warps, the sliding door and the frame body or the sliding doors rub against each other, which damages the side surface of the sliding door.

In particular, with the recent depletion of wood, plywood, fiberboard, laminated veneer lumber, particle board, oriented strand board, stick board, etc. are used as base materials.
In many cases, each member is formed by using a laminated body in which a decorative paper, a synthetic resin sheet, a decorative veneer, and the like are laminated on the surface, and these members are combined to form a sliding door.

When rubbing due to warping occurs in the sliding door having such a structure as described above, unlike a sliding door made of a solid material, the damaged portion due to rubbing cannot be cut and repaired. Furthermore, once the conventional door metal fitting is fixed to the lower end of the sliding door, the positional relationship between the door metal fitting and the sliding door cannot be relatively moved in the left-right direction thereafter. Therefore, when the sliding door is warped, the only way to replace it is to replace the entire sliding door, which is a serious problem.

[0007]

The door metal fitting 10 has an outer case 11 which is open at least at the lower end and a width outer dimension which is also at least open at the lower end and smaller than the inner width of the outer case. The inner case 23 is housed with a directional clearance, and the door roller 30 is housed in the inner case so as to be rotatably in close contact with each other in the width direction.

The outer case 11 has a pair of side plates 12 and 12 arranged with a predetermined width inside dimension, an upper plate 13 connecting the upper end portions of the side plates and extending further in the front-rear direction, and a rear end portion of the side plate. And a back plate 14 that connects the two.

The side plates 12 and 12 have vertical guide grooves 15 and 15 which are formed by cutting out upward in a substantially vertical direction from their lower ends. Further, a through hole 17 into which a left and right adjusting bolt 16 described later is inserted is formed in one or both of the side plates 12, 12. Further, a mounting hole 20 for mounting a fixing member 19 for fixing a vertical adjustment bolt 18 described later is formed.

The upper plate 13 is formed with screw holes 21 and 21 for attaching the door metal fitting 10 to the lower end of a sliding door (not shown) with screws (not shown).

The back plate 14 is formed with a laterally long through hole 22 into which the vertical adjustment bolt 18 is inserted (FIG. 3).

On the other hand, the inner case 23 is provided with a pair of side plates 24, which are arranged with a space between the side plates 12, 12 of the outer case 11, that is, a width outer dimension smaller than the width inner dimension of the outer case 11, 24, an upper plate 25 connecting the upper end portions of the side plates, and a back plate 26 connecting the rear end portions of the side plates are formed into a substantially U-shaped cross section.

The side plates 24, 24 have inclined guide grooves 27, 27 cut out obliquely rearward from the lower ends thereof. In addition, a screw hole 28 into which the tip end portion of the left and right adjusting bolt 16 that penetrates the through hole 17 of the outer case side plate 12 is screwed is formed.

The back plate 26 is formed with a screw hole 29 into which the tip of the vertical adjustment bolt 18 which penetrates the laterally long through hole 22 of the outer case back plate 13 is screwed (FIG. 4).

In the above structure, the inner case 23 is housed in the side plates 12 of the outer case 11, and the inclined guide groove 27 is formed.
In the opening where the vertical guide groove 15 and the vertical guide groove 15 overlap, the door axle 3
The door roller 30 is attached so that 1 is inserted. With the door axle 31 of the door roller 30 spanning the inclined guide groove 27 of the inner case 23, the inner case 23 is attached to the side plate 1 of the outer case 11.
It may be housed in 2, 12.

The laterally long through hole 2 in the outer case back plate 14
2, the vertical adjustment bolt 18 is inserted, and the tip end thereof is screwed into the screw hole 29 of the inner case back plate 26, and further, the fixing member 19 is fitted from the mounting hole 20 of the outer case side plate 12 to the back of the outer case. By holding the vertical adjustment bolt 18 from the inside of the plate 14, the housed state in which the inner case 23 is housed in the outer case 11 is secured.

The door metal fitting 10 is inserted into a recess obtained by sculpting a crosspiece at the lower end of the sliding door, and the outer case 11
Screw holes 21 and 21 provided in the front and rear extending portions of the upper plate 13
A fixing screw (not shown) is screwed in from below to be fixed.

The left and right adjusting bolts 16 are inserted through the through holes 17 of the outer case side plate 12, and the tips thereof are inserted into the inner case side plate 2.
4 is screwed into the screw hole 28. When the left and right adjustment bolts 16 are tightened in the tightening direction (clockwise), the inner case 23 moves laterally in a direction approaching the outer case 11, and when rotated in the opposite direction, the inner case 23 moves laterally in a direction away from the outer case 11. .

In this way, by operating the left and right adjustment bolts 16, the inner case 23 moves laterally relative to the outer case 11 fixed to the lower end of the sliding door, and the door roller 30 also moves as the inner case 23 moves. Since it moves, the positional relationship between the sliding door and the door roller 30 attached to the lower end of the sliding door can be adjusted in the left-right direction.

That is, since the door roller 30 is inserted into the sill groove (not shown) of the sill in the frame body and its position is regulated, the position of the sliding door is moved in a direction orthogonal to the opening / closing direction by operating the left / right adjusting bolt 16. It can be moved (left and right), and the clearance between sliding doors is 7
Is set to an appropriate minimum value, and further, when the appropriate clearance is impaired due to warpage of the sliding door itself, readjustment can be easily performed.

The vertical adjustment of the sliding door is performed by the vertical adjustment bolt 18
It is performed through the rotating operation of. That is, when the vertical adjustment bolt 18 is tightened in the tightening direction (clockwise), the inner case 23 approaches the outer case 14 (the back plates 14, 2).
6 move toward each other). As a result, the opening for supporting the door roller shaft 31, which is formed by overlapping the vertical guide groove 15 and the inclined guide groove 27, moves below the position shown in FIG. 1, and the door roller 30 moves to the outer case 11 and the inner case 23.
The projecting length projecting from the lower end edge of is increased. Therefore, the sliding door can be moved to a higher position.

When the vertical adjustment bolt 18 is rotated in the opposite direction, the inner case 23 moves in a direction away from the outer case 14, and the position of the sliding door can be moved downward.

Since the through hole 22 penetrating the vertical adjustment bolt 18 is formed horizontally in the outer case back plate 14, the positional relationship between the vertical adjustment bolt 18 and the inner case back plate 26 is maintained. Therefore, it is allowed to perform the left-right adjustment of the sliding door by operating the left-right adjustment bolt 16 described above. That is, the vertical adjustment and the horizontal adjustment of the sliding door can be performed separately and independently.

If necessary, between the outer case side plate 12 and the inner case side plate 24 to which the left and right adjusting bolts 16 are attached, or the outer case back plate 1 to which the up and down adjusting bolts 18 are attached.
A spring may be fitted between 4 and the inner case back plate 26.

[0041]

Since the door metal fitting of the present invention is movable in the left-right direction relative to the sliding door when attached to the lower end portion of the sliding door, it is fitted in the sill groove and its position is regulated. The sliding door can be adjusted and moved in the left-right direction with respect to the door metal fitting. Accordingly, it is easy to set the passing clearance between the sliding doors or between the sliding doors and the frame body to an optimum minimum value, and it is possible to improve the airtightness of the room.

Further, even if the sliding door is warped or the sill or the kamoi is deformed due to the distortion of the house, and the predetermined crossing clearance is widened or narrowed, the door metal fitting is attached to the sliding door. Until then, the passing clearance can be easily readjusted to a predetermined value, and damage to the sliding door can be prevented.
