Description

[Detailed Description of the Invention] The object of the present invention is to obtain an opening/closing door, mainly a sliding door, whose door roller can be easily replaced and whose position can be easily adjusted up and down or left and right.

In this invention, a base frame with a vertical inner groove is fixed to the bottom of the opening/closing door, screw rods are loosely attached to the support, and grips that hold both sides of the position adjustment body are screwed onto the screw rods so that they can be moved up and down. Then, the door wheel is removably mounted on the position adjustment body using a pressure plate, and the supporting body thus constructed is inserted into the inner groove and held, and the door wheel is made to protrude from the required position at the bottom of the base frame. This is an opening/closing door in which the door roller is configured to be able to roll on a rail, and an embodiment thereof will be described below with reference to the drawings. Reference numeral 1 designates a base frame having an inner groove 2 vertically provided therein, and an inwardly bent portion 1 at the upper part of the base frame 1.
a, 1a are arranged opposite to each other, and a gap 3 is provided between them in which the protruding part of the support body is inserted, and the inner groove 2 communicates with the outside through the gap 3, and extends outward to the bent parts 1a, 1a. Insertion grooves 4, 4 are provided oppositely, and an extension portion is provided below the base frame 1, and inwardly bent portions 1b, 1b are provided oppositely, and a gap 5 for door roller insertion is provided between them. will be established. In addition, door roller insertion holes 6 are transparently provided at required locations on the bottom wall 1c of the inner groove 2. 7 is a support body provided with a protrusion 7a. Reference numeral 8 denotes grippers, two of which are placed on the support 7 at a required interval, and the base part of the gripper 8 is fixed to the support 7 with screws 9, with the bifurcated parts of each gripper 8 facing both sides. Set up accordingly. The upper and lower ends of a screw rod 10 are loosely attached to the bifurcated portion of each gripper 8, respectively. Reference numeral 11 denotes a position adjustment body, whose both ends are inserted into the bifurcated portions of the gripper 8 and screwed into the screw rods 10, respectively. Front and rear edges of position adjustment body 11 (in Fig. 6)
is bent upward to provide rising edges 11a, 11a. Further, a door roller insertion hole 12 is transparently provided in the center part. Reference numeral 13 denotes a support frame insertion groove for the door roller, which is carved in the position adjustment body 11 so as to face opposite to the door roller insertion hole 12. Reference numeral 14 denotes a pressure plate, which has elongated holes 15 for position adjustment, and screws 16 are inserted into the holes and screwed into the position adjustment body 11 to fix the pressure plate 14 in place. Note that the pressure plate 14 is housed within the rising edges 11a, 11a of the position adjustment body 11, and its rotation is restricted. The door roller 17 has a door roller insertion hole 12
A door wheel 17 is inserted into the interior and one half thereof is exposed to the outside.
The support frame of the door roller that protrudes to the left and right (as shown in FIG. 5) is arranged between the position adjustment body 11 and the holding plate 14, and the disposed portions are fitted into the fitting grooves 13, and the screws 16 is screwed in to tighten the pressing plate 14 and press and fix the support frame of the door roller. Then, the support 7 thus constructed is inserted into the inner groove 2, and the protruding portion 7a is inserted into the gap 3 to closely close the gap 3, and one half of the door roller 17 is in communication with the door roller. It is inserted into or out of the gap 5 through the insertion holes 12 and 6. Note that the door roller 17 is usually attached to the position adjustment body 11 from the outside of the base frame 1 after the support body 7 is inserted into the inner groove 2 as described above. It goes without saying that the door roller fitting holes 12 and 6 should be formed to have a width that allows this. In addition, the entire bottom wall 1c, or
The support body 7 may be configured to be able to be inserted into the inner groove 2 even after the door roller 17 is attached to the position adjustment body 11 by taking a partial removal means or the like. Reference numeral 18 denotes a door main body, and the top surface of the base frame 1 is brought into contact with the bottom surface of the door main body. Reference numeral 19 is a connecting plate, located at the front and rear of the door body 18 and the base frame 1 (in Fig. 1).
The bent portions 19a provided on the connecting plate 19 are inserted into the insertion grooves 4, 4, and the screws 20 are used to tighten the connecting plate 19.
is fixed to the door body 18, and the door body 18 and the base frame 1 are connected. It goes without saying that the door body 18 and the base frame 1 may be fixed together by other general fixing means (for example, with screws, etc.). Reference numeral 21 denotes an abutment plate that abuts both sides of the base frame 1 and has screws 22 and 23.
are fixed to the door main body 18 and the protruding portion 7a. In addition, the base frame 1 and the support body 7 are usually one each for one door body 18, but the position adjustment body 1
1 is usually on both sides of one support 7, or
If necessary, install them between both sides, and install door roller 1.
7, two, or several if necessary, are used for one door body 18. In addition, Fig. 4,
FIG. 5 is proportionally larger than FIGS. 2 and 3.

The operation of the present invention will be explained based on the above-mentioned embodiments. When the screw rod 10 is rotated, the position adjustment body 11 is raised or lowered according to the direction of rotation. This allows the vertical position of the door roller 17 to be adjusted. Spiral nail 1
6, remove the pressure plate 14, remove the door roller 17 from the support frame fitting groove 13 (remove the old door roller 17), replace it with another (new) door roller 17, and arrange the pressure plate 14 as described above. Then screw the screw 16 into the pressing plate 1.
4 is fixed again to hold the door roller 17. A portion of the door roller 17 is normally exposed to the outside through the gap 5 for insertion of the door roller. Since the holding plate 14 is fixed by inserting a screw 16 into the elongated hole 15, it can be moved left and right within the width of the elongated hole 15, and its horizontal position can be adjusted as necessary. do. The opening/closing door of the present invention is normally used as a sliding door by general means, but it can also be used as a Western-style lifting door.

Since the present invention is as described above, when the door roller becomes old and loses its smoothness in use, it can be easily replaced even by an amateur or a person, and the base frame, support, position adjustment body, and other bases can be easily replaced. All the fixtures installed in the frame are usually made of metal, so they do not get damaged even if they are replaced many times, and the door wheel is frequently replaced to ensure that the door always opens and closes smoothly The position of the door roller can be easily adjusted to fit the door into the rail, and the door can be easily fitted into the rail, making it possible to cope with wear of the rail, thereby significantly increasing the service life of the door. have
