DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described with reference to the drawings. 1 is a perspective view of a door structure showing an embodiment of the present invention, and FIG. 2 is a perspective view showing a state in which the door structure is shortened in a longitudinal direction. This door structure 1
Is provided with a base portion 10 as a long member having a U-shaped cross section with the release side facing upward, and is formed so that it can be inserted into the groove a (see FIG. 5) on the duck side A. The base portion 10 has a form in which it is divided into two parts at an intermediate portion in the longitudinal direction, but it is formed in a continuous continuous state by a connecting member 20 as a joint member for connecting the butt end portions side to form a nose. ing.

The connecting member 20 is formed of a rectangular columnar member having a rectangular cross section, and can be inserted into the base portion 10 having a U-shaped cross section. The outer shape of the central portion 20a of the connecting member 20 is formed thicker than the insertion portion 20b with respect to the base portion 10,
It has the same shape as the outer shape of the base portion 10. Base part 10
Can be inserted up to the central portion 20a of the connecting member 20, and the base portion 10 can be inserted into any position from both sides of the connecting member 20. Therefore, as shown in FIG. 2, the length of the entire base portion 10 can be adjusted by adjusting the insertion positions of the base portion 10 and the connecting member 20, and the base portion 10 can be adjusted according to the width of the sliding door. Since the length of the door can be determined, it can be applied to sliding doors having various widths.

Further, in this door structure 1, as shown in FIGS. 3 to 6, a brake device 30 is provided near the end of the base portion 10 opposite to the connecting member 20 side. Brake device 3
In No. 0, the first sliding contact member 31 made of a member having a large frictional resistance is provided inside the opposing wall of the base portion 10 having a U-shaped cross section, and the first sliding contact member 31 is mounted in the groove a on the side of the duck A. Two sliding contact members 32 are provided. The second sliding contact member 32 is slid in the groove a on the side of the Kamoi A, in the direction of closing the sliding door, and immediately before the sliding door is closed, the first sliding contact member 31 is placed.
The sliding door can be prevented from hitting a pillar or the like strongly by mounting the sliding door at a position where it can slide.

The second sliding contact member 32 is a member having a rectangular cross section which is slightly elongated in the moving direction of the sliding door, and both side surfaces slidingly contacting the first sliding contact member 31 are in a direction orthogonal to the moving direction. The movable plate 32a is movable. The movable plate 32a has a large friction coefficient on the outer surface side and is configured to generate frictional resistance by slidingly contacting the first sliding contact member 31. The inner surface of the movable plate 32a is formed to be slightly inclined in the moving direction, and the movable plates 32 on both sides are formed.
By arranging a symmetrically, the space between them is gradually narrowed in the longitudinal direction.

Then, between these movable plates 32a,
A spacer 34 for adjusting the width of the movable plate 32a is provided. The spacer 34 is in contact with the inside of the movable plate 32a, and by sliding the spacer 34 in the longitudinal direction y of the movable plate 32a, the outer width of both movable plates 32a can be adjusted. By changing the contact force with respect to the contact member 31, the frictional force generated between the contact member 31 and the second sliding contact member 32 can be adjusted.

Since this door structure 1 can be attached to a sliding door having a flat upper part on the side of the duck, the sliding door can have a simple structure and can be easily formed. The door structure 1 connects the base portion 10 to the connecting member 2
Since the connection is made with 0, it is possible to accommodate different sliding door widths. By sliding the base portion 10 in the longitudinal direction and adjusting the fitting length with the connecting member 20, it is possible to adjust according to the width of the sliding door,
The door neck 1 is fixed in a state where the end of the base 10 and the end of the sliding door are aligned with each other.

As shown in this embodiment, the connecting member 2
By providing 0 in the middle part of the sliding door, it is possible to construct a door structure by preparing two base parts 10 having the same shape, which contributes to improvement in productivity. The second sliding contact member 32 constituting the brake device 30 is mounted in a predetermined position near the pillar in the groove a on the side of the duck A. As the mounting position, it is preferable to operate the brake immediately before the sliding door is closed, but it can be mounted at an optimum position in consideration of the shape, weight, and other factors of the sliding door.

The braking force is adjusted by sliding a spacer 34 for adjusting the outer width of the movable plate 32a. By moving the spacer 34 to the side where the gap between the movable plates 32a is narrow, the outer width of the second sliding contact member 32 can be expanded, and the frictional force with the first sliding contact member 31 can be increased. Therefore, the braking force on the sliding door can be increased. On the contrary, by moving the spacer 34 to the side where the distance between the movable plates 32a is wide, the outer width of the second sliding contact member 32 can be reduced, and the first sliding contact member 31
The frictional force with can be weakened.

Therefore, by using the door structure 1, when the sliding door is closed, a braking force is exerted on the sliding door immediately before the closing so that the sliding door does not hit the pillar strongly. Therefore, the impact sound is not emitted from the sliding door, and the risk that the hand or the finger is caught between the sliding door and the pillar can be eliminated. In the above embodiment, the example in which the base portion 10 is divided into two and integrated by the connecting member 20 is shown. However, one of the base portions 10 can be inserted from the end portion of the other base portion 10, The total length can be configured to be adjustable. In this case, since the connecting member 20 is not necessary, the number of parts can be reduced.

The base portion 10 may be divided into three or more parts. In this case, the connecting member 20 may be provided for each divided portion. In this embodiment, it is possible to cope with a case where the width of the sliding door is long, and it is possible to shorten each base portion 10 to improve productivity and handleability. The sliding door can be made of aluminum or any other structure as long as it can be moved in the width direction of the sliding door in addition to wood.
