At the lower end of the sliding door, there is formed a concave portion obtained by digging the crosspiece, and the door wheel is mounted in the concave portion so as to be slidable in a direction parallel to its axial direction. That is, the door roller is provided movably in a direction parallel to its axial direction, in other words, in a direction (left-right direction) orthogonal to the opening and closing direction of the sliding door when attached to the lower end of the sliding door. Thereby, the positional relationship between the door roller and the sliding door can be adjusted in the left-right direction.

The sliding door is fitted in a sill groove formed in a sill of a frame body that accommodates the sliding door so that the sliding door can be opened and closed, and the position of the sliding door is regulated. As a result, the sliding doors pass each other (in the case of the sliding type) or the sliding doors and the frame body (in the case of the single sliding type), so that the clearance can be adjusted.

Further, even if the predetermined sliding clearance is widened or narrowed due to warpage of the sliding door, the sliding door is relatively moved in the left-right direction according to the above-mentioned procedure, so that the sliding clearance is set to a predetermined value. It is easy to readjust.

FIGS. 1 to 7 show a sliding door structure according to an embodiment of the present invention. This sliding door structure consists of threshold 1 and gate 2
The inside of a frame 4 composed of a pair of right and left vertical frames 3 and 3 is provided in an opening, and sliding doors 5 and 5 are provided in the frame 4 so as to be openable and closable.

A pair of parallel sill grooves 6, 6 are formed in the sill 1 to guide the running of a door wheel mounted on the lower ends of the sliding doors 5, 5. Similarly, a pair of parallel ditch grooves (not shown) are also formed in the duck gate 2, and accommodate the upper end portions of the sliding doors 5 and 5 and function as guide grooves when the sliding doors are opened and closed.

In FIG. 2, although slightly exaggerated, the clearance 7 between the sliding doors 5 is set to a very small dimension of about several millimeters in order to enhance the hermeticity of the room when the sliding doors are closed. Is set to

The door swing metal fittings 10 attached to the lower ends of the sliding doors 5 and 5 can be slid and adjusted in a direction parallel to the axial direction of the sliding doors 5, in other words, in a horizontal direction orthogonal to the opening and closing direction of the sliding doors 5 and 5 in the mounted state. FIG. 3 to FIG. 7 show examples of the configuration.

The door roller bracket 10 has an outer case 11 having at least a lower end opened, and a width having at least a lower end opened and a width smaller than the inner width of the outer case. An inner case 23 is housed with a directional clearance, and a door wheel 30 is rotatably housed in the inner case so as to be substantially close in the width direction and rotatable.

The outer case 11 has a pair of side plates 12, 12 arranged with a predetermined width and inner dimensions, an upper plate 13 connecting the upper ends of the side plates and extending in the front-rear direction, and a rear end of the side plates. Is formed in a substantially U-shaped cross section from the back plate 14 connecting the two.

The side plates 12, 12 have vertical guide grooves 15, 15 cut out substantially vertically upward from the lower ends thereof. In addition, 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 provided with a screw hole 2 for attaching the door roller fitting 10 to the lower end of the sliding door 5 with a screw (not shown).
1 and 21 are formed.

The back plate 14 is formed with a horizontally long through hole 22 through which the vertical adjustment bolt 18 penetrates (FIG. 5).

On the other hand, the inner case 23 has a pair of side plates 24 arranged at intervals so as to provide an interval between the side plates 12, 12 of the outer case 11, that is, a width outside dimension smaller than the width inside dimension of the outer case 11. 24, an upper plate 25 connecting the upper ends of the side plates, and a back plate 26 connecting the rear ends of the side plates, are formed in a substantially U-shaped cross section.

The side plates 24, 24 have inclined guide grooves 27, 27 which are cut out obliquely rearward from the lower ends thereof.

The back plate 26 is formed with a screw hole 29 for screwing the tip of the vertical adjustment bolt 18 that passes through the horizontally long through hole 22 of the outer case back plate 14 (FIG. 6).

In the above configuration, the inner case 23 is housed in the side plates 12 of the outer case 11 and
And the vertical guide groove 15 are overlapped with each other.
1 is inserted, and the door roller 30 is attached. The inner case 23 is attached to the side plate 1 of the outer case 11 in a state where the door shaft 31 of the door roller 30 is bridged over the inclined guide groove 27 of the inner case 23.
It may be housed in 2, 12.

Then, the horizontally long through hole 2 of the outer case back plate 14 is formed.
2 is screwed into the screw hole 29 of the inner case back plate 26, and the fixing member 19 is fitted through the mounting hole 20 of the outer case side plate 12 to fit the outer case back. By holding the vertical adjustment bolt 18 from the inside of the plate 14, the stored state where the inner case 23 is stored in the outer case 11 is secured.

The door roller fitting 10 penetrates into a recess (not shown) obtained by digging a bar at the lower end of the sliding door 5, and is provided in a front-rear extension of the upper plate 13 of the outer case 11. A fixing screw (not shown) is screwed into the screw holes 21 and 21 from below to be fixed.

The vertical adjustment of the sliding door 5 is performed by the vertical adjustment bolt 1.
8 is performed through the rotation operation. That is, when the vertical adjustment bolt 18 is tightened in the tightening direction (clockwise),
The inner case 23 moves in the direction approaching the outer case 14 (the back plate 14,
26 in the direction in which they approach each other. Thereby, the opening for supporting the door axle 31 formed by overlapping the vertical guide groove 15 and the inclined guide groove 27 is moved downward from the position in FIG. 3, and the door wheel 30 is moved to the outer case 11 and the inner case 2.
The protrusion length protruding from the lower edge of the third member 3 is increased. Therefore,
The sliding door 5 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 5 can be moved downward.

Since the through hole 22 penetrating the vertical adjustment bolt 18 is formed in the outer case back plate 14 to be horizontally long, the positional relationship between the vertical adjustment bolt 18 and the inner case back plate 26 (thereby, the sliding door) 5 height is determined)
It is permissible to perform the left and right adjustment of the sliding door while maintaining the condition.

If necessary, a spring may be inserted between the outer case back plate 14 on which the vertical adjustment bolts 18 are mounted and the inner case back plate 26.

The left and right adjustment bolts 32 are threaded through screw holes 34 provided in the back plate 14 of the outer case 11 and
Of the inner case back plate 26 is bent into an L-shape in a direction perpendicular to the axial direction of the inner case back plate 26, and the rotating arm 33 is integrated therewith. It is configured to have the same.

In order to perform left-right adjustment in the door roller bracket 10, the rotation arm 33 of the left-right adjustment bolt 32 is brought into contact with any one of the left and right inner case side plates 24, and is rotated in a direction to further press the side plate 24. Manipulate.

For example, the left / right adjustment bolt 32 is further rotated clockwise in the figure from the state of FIG. 7 in which the tip of the rotating arm 33 is in contact with one side plate 24a of the inner case 23. Accordingly, the inner case 23 moves in a direction approaching the corresponding one of the side plates 12a of the outer case 11. That is, since the inner case 23 moves in the left-right direction relatively to the outer case 11 and the door wheel 30 moves accordingly, the position of the sliding door 5 is moved in a direction orthogonal to the opening and closing direction (left-right direction). And the clearance 7 (FIG. 2) can be adjusted. The length of the rotating arm 33 is set according to the required left and right adjustment allowance. In order to allow the inner case 23 to move relative to the outer case 11 in the left and right direction, a through hole 35 through which the shaft of the left and right adjustment bolt 32 is inserted is formed in the inner case back plate 26 to be horizontally long.

When such a left-right adjustment bolt 32 is used, the tip of the rotating arm 33 is always fixed to the inner case side plate 24.
It is preferable to secure a state of being in contact with the inside of a. For example, the outer case side plate 12a and the inner case side plate 2
4a between the inner case side plate 24
It is preferable to always urge a to the right in FIG.

[0045]

According to the present invention, the sliding door can be moved in the left-right direction when it is attached to the lower end of the sliding door. Therefore, the sliding door can be adjusted in the left-right direction with respect to the sliding door fitted in the sill groove and restricted in position. can do. Thereby, it is easy to set the clearance between the sliding doors or between the sliding door and the frame at an optimal minimum value, and it is possible to improve the indoor airtightness.

Further, even when the sliding door is warped or deformed due to the distortion of the house and the threshold, etc., as a result, the clearance is widened or narrowed by a predetermined distance, the door wheel remains attached to the sliding door. Thus, the passing clearance can be easily readjusted to a predetermined value, and damage to the sliding door can be prevented.
