(First Embodiment)

Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. A slider support device 12 is provided in the panel lower frame 11, and a support shaft 12a protrudes from the support device 12 below the lower frame 11 and is formed of synthetic resin below the support shaft 12a. The slider 13 is attached so as to be rotatable in the axial direction. The support shaft 12a is supported by the support device 12 so as to be rotatable in a horizontal direction and protrude and retract in a vertical direction. Accordingly, the slider 13 is supported so as to be rotatable in the horizontal direction with respect to the panel and rotatable along the rail. The support device 12 and the slider 13 are provided at the center in the width direction of each panel as in the conventional example shown in FIG.

The slider 13 is engaged with a lower rail 14 that is exposed and mounted on the floor F, and is movable along the lower rail 14. As shown in FIGS. 2 (a)-(c), a first engaging portion 15a-15d and second engaging portions 16a, 16b are formed below the slider 13 as an engaging means. ing. The first engaging portions 15a to 15d are disposed on both sides in the front-rear direction of the slider 13, and the second engaging portions 16a and 16b are disposed therebetween. This Here, the front-back direction refers to the moving direction of the slider 13 (longitudinal direction in FIG. 2A), and hereinafter, the left-right direction in FIG. 2A is defined as the width direction of the slider 13.

The first engaging portions 15a to 15d include engaging ends 15e to 15h whose positions near the lower ends protrude outward in the width direction of the slider 13. A first upper slope 17a-17d as a slope is formed at the upper part of the engagement end 15e-15h, and a lower slope 18a-18d as a slope at the lower part of the engagement end 15e-15h. Each is formed.

[0024] In the width direction of the slider 13, a slit 19 is formed inside the first engagement portions 15a to 15d so as to face upward. The first engaging portions 15a to 15d can be elastically deformed in the width direction of the slider 13 by forming the slit 19.

[0025] The lower ends of the second engaging portions 16a and 16b are formed so as to slightly protrude below the first engaging portions 15a to 15d. The positions near the lower ends of the second engaging portions 16a and 16b protrude on both sides in the width direction of the slider 13. Further, the second engaging portions 16a and 16b are set such that the outer ends are located inside the front ends of the first engaging portions 15a to 15d in the width direction of the slider 13. I have. A second upper slope 20a-20d is formed above each end!

As shown in FIGS. 1 and 3 (a)-(c), the lower rail 14 is provided with the first engaging portions 15a and 15d and the second engaging portions 16a and 16b so as to be movable. Two locking grooves 21a and 21b for supporting are formed. The lower rail 14 is formed of an extruded aluminum material and is exposed and attached on the floor surface F. And it is formed so that the height from the floor F is about 3 mm.

[0027] On both sides of the locking grooves 21a, 21b, rail slopes 22a-22d facing each other are formed. The rail slopes 22a-22d are formed obliquely downward so as to face the first upper slopes 17a-17d and the second upper slopes 20a-20d.

[0028] The locking grooves 21a and 21b thus formed are formed narrower as approaching upward, and open ends 14a to 14d are formed at the upper ends thereof. The distance between the opening end 14a and the opening end 14b is set substantially equal to the width of the lower end of the second engaging portion 16a, and the distance between the opening end 14c and the opening end 14d is the second engagement. The width is set substantially equal to the width of the lower end of the portion 16b. Also, the distance between the opening end 14a and the opening end 14d is determined by the distance between the engagement end 15e and the engagement end 1d. It is set smaller than the interval between the engaging end 5h and the interval between the engaging end 15g (see FIG. 2 (a)) and the engaging end 15h.

Next, the operation of the slider 13 and the lower rail 14 configured as described above will be described. As shown in FIG. 3 (a), when attaching the slider 13 to the lower rail 14, first, the slider 13 is set so that the second engagement portions 16a, 16b are directly above the locking grooves 21a, 21b. Position the. At this time, at both ends in the width direction of the slider 13, the engagement ends 15e to 15h protrude outside the opening end 14a or the opening end 14d. Therefore, the lower slopes 18a-18d (see FIG. 2 (b)) abut on the lower rail 14.

When the slider 13 is pressed downward from the state shown in FIG. 3A, as shown in FIG. 3B, the first engagement portion 15a—15d is moved to the lower slope 18a. — The slider 13 is moved downward while being elastically deformed gradually along the width of the slider 13 along 18d.

When the slider 13 is moved further downward from the state shown in FIG. 3 (b), the distance between the two rail slopes 22a-22d gradually increases, so that the first engagement portions 15a-15d As shown in FIG. 3 (c), the original state, that is, the engagement ends 15e to 15h return to the outside of the opening end 14a or the opening end 14d, and the assembly of the slider 13 is completed.

When the slider 13 assembled to the lower rail 14 in this manner is inclined to one side by receiving a force in the width direction, as shown in FIG. 4, for example, the first upper slopes 17a, 17c and the The second upper slope 20a approaches the rail slope 22a. At this time, the first upper slopes 17b and 17d and the second upper slope 20d no longer engage with the rail slope 22d, but the second upper slope 20c engages with the rail slope 22c. Therefore, even if a lateral force acts on the slider 13, the slider 13 can be reliably prevented from coming off the lower rail 14.

When the slider 13 is to be removed from the lower rail 14, the slider 13 is lifted upward so that the engagement ends 15e—15h are moved upward as shown in FIG. 3 (b). The first engagement portions 15a to 15d are guided upward along the slopes 17a to 17d, and are moved upward while being elastically deformed to the inside in the width direction of the slider 13.

Then, the slider 13 is removed from the lower rail 14 by further pulling the slider 13 upward from the state shown in FIG. 3 (b). Slider 13 and 13 configured as above With the lower rail 14, the following effects can be obtained.

The engagement between the Oa-20d and the slopes 22a-22d prevents the slider 13 from being disengaged from the lower spring 14 force.

(3) By elastically deforming the first engaging portions 15 a-15 d inward in the width direction of the slider 13, the slider 1 is moved from above the lower rail 14 or toward above the lower rail 14.

3 can be attached or detached. Therefore, it is possible to improve the workability of assembling the slider 13 without having to engage the slider 13 from the end of the lower rail 14.

(4) Since the first engaging portions 15a-15d are formed with the lower slopes 18a-18d, the first engaging portions 15a-15d can be easily formed along the lower slopes 18a-18d. Since the slider 13 can be elastically deformed, the slider 13 can be easily attached to the lower rail 14.

[0038] (5) The slider 13 is configured such that the first engaging portions 15a and 15c and the second engaging portion 16a are engaged with one of the locking grooves 21a of the lower rail formed by the two sections. The first engaging portions 15b and 15d and the second engaging portion 16b are engaged with the locking groove 2 lb. Therefore, even when the slider 13 is inclined by receiving a force in the width direction, the first engagement portions 15a to 15d engaging with the both locking grooves 21a and 21b surely remove the slider 13 from the lower rail 14. Can be prevented

(6) When the slider 13 moves upward, the engagement ends 15e-15h are formed at positions where they engage with the open ends 14a-14d. Therefore, it is possible to prevent the slider 13 from easily coming off.
