  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a perspective view of a cabinet equipped with a flat sliding door. This cabinet is used as, for example, a storage cabinet installed in a narrow space. A flat sliding door composed of two sliding doors 2 and 3 is provided at the front edge of the front opening of the cabinet. It is hold | maintained between 20 and is mounted | worn so that driving | running | working is possible.

  The main body of the sliding doors 2 and 3 is formed of, for example, plywood, and grips 2 a and 3 a are provided at outer ends of the sliding doors 2 and 3. Further, a lower sliding member 6 and a lower sliding pin 7 are attached to the lower ends of the sliding doors 2 and 3 so as to protrude downward. 2 and 3 show the left sliding door 2, and the lower sliding member 6 is attached to the lower end of the right end, and the lower sliding pin 7 extends from the center to the lower end of the left side. It is attached. Although the illustration of the right sliding door 3 is omitted, the right sliding door 3 is formed symmetrically with the left sliding door 2, and the lower sliding member 6 is attached to the lower end of the left end of the sliding door 3. A pin 7 is attached to a lower end portion on the right side from the center.

  As shown in FIG. 4, the lower sliding member 6 has a substantially oval sliding portion 62 secured to a lower portion of a substantially L-shaped mounting portion 61 with a fixing screw 64 and a nut 65 via a spacer 63. It is formed with attached. A plurality of spacers 63 are formed from an oval thin synthetic resin plate, and the height position of the sliding portion 62 can be adjusted by changing the number of overlapping spacers 63. The sliding part 62 has a substantially oval planar shape and is formed with a convex curved surface at the bottom thereof, and smoothly slides by engaging loosely with an upper rail groove 11 of the lower rail 10 described later. It is formed as follows. The contact portion between the mounting portion 61 and the sliding portion 62 is formed with a concave and convex fitting portion, and the fitting portion is fitted together so that both are fitted.

Is formed. The sliding pin 72 is insert-molded into a substantially bullet shape with a synthetic resin using a sleeve 72a threaded with a female screw on the inside, and is screwed into a screw portion of a fixing bolt 74 projecting on the mounting portion 71 side. . The sliding pin 72 having a substantially hemispherical portion at the tip can smoothly slide in the lower rail groove 12 of the lower rail 10 described later.

  The sliding pin 72 is fitted in the center of the mounting portion 71 and is fixed by screwing the sleeve 72a into the screw portion of the fixing bolt 74, while the number of washer-shaped spacers 73 inserted into the base portion of the screw portion is set. By changing, the height position of the sliding pin 72 of the lower sliding pin 7 can be adjusted. The length of the sliding pin 72 is shorter than a sliding pin 92 of the upper sliding pin 9 described later, for example, 8 mm, and the spacer 73 is formed in a washer shape made of synthetic resin having a thickness of 1 mm, for example. The spacer 73 is interposed at the base of the moving pin 72 so that the height of the lower sliding pin 7 can be adjusted to 8 mm + α. The spacer 73 is inserted into the fixing bolt 74 while adjusting the number of inserted sheets, and the sliding pin 72 is fixed to the mounting portion 71.

  The length of the sliding pin 72 of the lower sliding pin 7 is, for example, 8 mm as described above, and is shorter than the length of the sliding pin 92 of the upper sliding pin 9 (for example, 11 mm). The lower rail groove 12 of the lower rail 10 with which the sliding pin 72 of the lower sliding pin 7 engages is shallower than the depth of the upper rail groove 21 of the upper rail 20 with which the sliding pin 92 of the upper sliding pin 9 engages. This is because it is formed. As shown in FIGS. 22 and 23, the auxiliary rails 19a and 19b are fitted into the lower rail groove 12 to reduce the depth of the rail groove, thereby deteriorating the appearance of the lower rail 10 and foreign matters in the rail groove. To prevent falling. On the other hand, the length of the sliding pin 92 of the upper sliding pin 9 is formed to be longer, for example, 11 mm as will be described later, and this sliding pin 92 engages with the deeper upper rail groove 21 of the upper rail 20 to slide. It travels dynamically to prevent the sliding doors from coming off and to make them run stably. As shown in FIG. 5, mounting holes 71 for screwing the sliding doors 2 and 3 in the thickness direction and the vertical direction of the plywood body are formed in the mounting portion 71 of the lower sliding pin 7, respectively.

The mounting portion 61 of the lower sliding member 6 and the mounting portion 81 of the upper sliding member 8 can have the same shape, and therefore the same parts can be used together. In FIG. 6, the spacer as described above is not interposed between the mounting portion 81 and the sliding portion 82, but the upper sliding member 8 also has a height between the mounting portion 81 and the sliding portion 82. An adjustment spacer can be inserted.

  As shown in FIG. 7, the upper sliding pin 9 has a substantially cylindrical sliding pin 92 fastened and fixed by a fixing bolt 94 through a spacer 93 on top of a substantially L-shaped mounting portion 91. Is formed. Similar to the sliding pin 72, the sliding pin 92 is insert-molded into a substantially bullet shape with a synthetic resin using a sleeve 92a threaded with an internal thread as an insert. The groove 21 is loosely engaged and can slide. The sliding pin 92 is fitted in the center of the mounting portion 91 and is fixed by screwing the sleeve 92 a into the threaded portion of the fixing bolt 94. Further, the height position of the sliding pin 92 can be adjusted by changing the number of overlapping spacers 93 inserted into the base portion of the fixing bolt 94.

  The length of the sliding pin 92 of the upper sliding pin 9 is set to a length necessary for stably sliding the sliding door, for example, 11 mm. From the length of the sliding pin 72 of the lower sliding pin 7 It is formed long. For example, a synthetic resin spacer 93 having a thickness of 1 mm is interposed at the base of the sliding pin 92 so that the height of the upper sliding pin 9 can be adjusted to 11 mm + α. The sliding pin 92 engages in an upper rail groove 21 having a sufficient depth of the upper rail 20 described later, and can smoothly and stably slide in the upper rail groove 21. Further, similarly to the above, the attachment portion 91 is provided with attachment holes for screwing the sliding doors 2 and 3 in the thickness direction and the vertical direction of the plywood body.
