[0011] (Embodiment of the inner block) An example of an embodiment of the inner block 50 of the present invention will be described with reference to the drawings. For the sake of convenience, in the following description, the upper side will be referred to as "up," the lower side as "down," the leading edge as "front," the trailing edge as "rear," the left side in the direction of closing the sliding door as "left," and the right side as "right."

[0012] The inner block 50 of the present invention is used by being installed within the rail R on which the suspension roller 41 (Figure 2(b)) for the sliding door D (Figure 5) runs. As an example, the inner block 50 shown in Figures 1(a) and 1(b) comprises a door stopper 10 and a sliding door holder 20. As shown in Figures 2(a) and 2(b), the door stopper 10 is installed (fixed) to the rail R with screws 30.

[0013] The door stopper 10 is a member that the sliding door D abuts against. As shown in Figure 1(b), the door stopper 10 in this embodiment is a rectangular block and includes a first mounting portion 11 on which the sliding door holder 20 rests, a second mounting portion 12 that is one level higher than the first mounting portion 11, and two support columns 13 that protrude upward from the second mounting portion 12.

[0014] The doorstop body 10 is provided with a doorstop body side locking portion 14 for locking the sliding door holding body 20. In this embodiment, as the doorstop body side locking portion 14, it includes a circumferential surface locking portion 14a provided on the left and right circumferential surfaces of the second placement portion 12, and a back surface locking portion 14b provided on the back side of the two support pillars 13.

[0015] The first placement portion 11 and the second placement portion 12 are provided with screw holes 15 penetrating in the thickness direction (vertical direction). These screw holes 15 are for inserting screws 30 used when fixing the doorstop body 10 within the rail R.

[0016] The two support pillars 13 are provided at intervals. This interval is set to a width that can accommodate the catch portion 22b (described later) of the sliding door holding body 20. The support pillar 13 of this embodiment is triangular prism-shaped in plan view, and a curved concave portion is formed on the inner surface of each support pillar 13.

[0017] The doorstop body 10 is provided with a flat contact surface 16 against which the sliding door D abuts. Although not shown in the figure, a cushioning material such as a rubber pad or a silicon pad can be provided on the contact surface 16. By providing the cushioning material, effects such as alleviating the impact sound between the sliding door D and the doorstop body 10 and preventing damage to the doorstop body 10 can be expected.

[0018] The sliding door holding body 20 is a member that holds the sliding door D at an arbitrary position within the rail R. As shown in FIG. 1(b), the sliding door holding body 20 of this embodiment is a U-shaped member in side view in which a lower structure portion 21 placed on the first placement portion 11 and an upper structure portion 22 placed on the second placement portion 12 are integrally formed.

[0019] The lower structure portion 21 of this embodiment includes two locking arms 21a arranged at intervals. The two locking arms 21a are sized and shaped to be placed on the first placement portion 11, and at the tip of the free end of both locking arms 21a, a holding body side locking portion 21b for locking to the back surface locking portion 14b is provided.

[0020] The upper structure 22 is provided with an insertion hole 22a that penetrates in the thickness direction. This insertion hole 22a is a through hole for passing a screw 30 through, and is sized so that the screw 30 does not come into contact with the inner circumferential surface after passing through.

[0021] A catch portion 22b that protrudes forward is provided on the free end side of the upper structure portion 22. The catch portion 22b is provided with a triangular locking projection 22c in side view. This locking projection 22c is the part that locks into a locking recess 41a formed on the suspension wheel 41, which is a component of the suspension wheel unit 40 (Figure 6(a)(b)).

[0022] In this embodiment, with the sliding door holder 20 placed on the door stopper 10, the locking portion 14 on the door stopper side and the locking portion 21b on the holder side are locked together, thereby preventing the sliding door holder 20 from coming off in the vertical direction without the use of fasteners such as set screws. The catch portion 22b of the sliding door holder 20 held by the door stopper 10 is designed to move up and down (rotate in a direction approaching the suspension wheel 41 and in a direction away from the suspension wheel 41) when it is locked into the locking recess 41a.

[0023] In this embodiment, the inner block 50 is used by being fixed within the rail R on which the suspension wheel 41, which is equipped on the sliding door D, travels. Specifically, the inner block 50 is fixed to the rail R by inserting a screw 30 from below into the screw hole 15 of the door stop 10 on which the sliding door holder 20 is placed and screwing it in, and pressing the tip of the screw 30 against the upper surface of the rail R.

[0024] The inner block 50, configured as described above, has the external appearance shown in Figures 3(a) to 3(f). Figure 3(a) is a front view of the inner block 50 of Figure 1(a), Figure 3(b) is a rear view of Figure 1(a), Figure 3(c) is a left side view of Figure 1(a), Figure 3(d) is a right side view of Figure 1(a), Figure 3(e) is a top view of Figure 1(a), and Figure 3(f) is a bottom view of Figure 1(a).

[0025] (Other embodiments of the inner block) In the above embodiment, the case in which the door stopper 10 and the sliding door holder 20 are used simultaneously is given as an example. However, the inner block 50 of the above embodiment can also be used with the door stopper 10 alone, with the sliding door holder 20 removed, as shown in Figures 4(a) and 4(b).

[0026] Even when using the door stopper 10 alone, the door stopper 10 can be fixed to the rail R by inserting a screw 30 from the bottom of the screw hole 15 of the door stopper 10 and screwing it in, and pressing the tip of the screw 30 against the upper surface of the rail R.

[0027] The configuration of the inner block 50 described in this embodiment is just one example, and the configuration of the inner block 50 of the present invention is not limited to the configuration of the above embodiment. The inner block 50 of the present invention can be modified by omitting, replacing, adding, or otherwise altering its configuration without changing its essence.

[0028] (Embodiment of a sliding door device) Next, an example of the sliding door device 60 of the present invention will be described. Here, we will use the case in which the inner block 50 of the above embodiment is used as an example. Since the inner block 50 has already been described, its description will be omitted here.

[0029] As an example, the sliding door device 60 shown in Figure 5 comprises a sliding door D equipped with a suspension unit 40 at its top, a rail R on which the sliding door D travels, and an inner block 50 installed (fixed) within the rail R. Existing or new sliding door D, suspension unit 40, and rail R can be used.

[0030] As an example, the suspension traction unit 40 shown in Figures 6(a) and 6(b) was previously developed by the applicant and, as shown in Figures 6(a) and 6(b), comprises a suspension traction unit 41, a case 42, an anti-bouncing device 43, an up-and-down position adjuster 44, a left-and-right position adjuster 45, a connector 46, a retaining device 47, a front cover 48, and a case holder 49.

[0031] In the suspension unit 40 of this embodiment, since the anti-bouncing device 43 is located in front of the connector 46, a sliding door holder of the type that holds the sliding door D by pressing on the upper side of the wheel, or a sliding door holder of the type that holds the sliding door D by sandwiching the connecting shaft, cannot hold the sliding door D at an arbitrary position.

[0032] In contrast, the inner block 50 of this embodiment holds the sliding door D by engaging the locking projection 22c of the catch portion 22b with the locking recess 41a formed on the upper surface of the suspension wheel 41, so that the sliding door D can be held in any position.

[0033] (Other embodiments of sliding door devices) In the above embodiment, the inner block 50 is provided as an example at the rear end of the rail R, but in the sliding door device 60 of the present invention, the inner block 50 can also be provided at the leading end of the rail R. In this case, the closed sliding door D can be held by the catch part 22b, preventing the sliding door D from opening unintentionally.

[0034] Furthermore, the inner block 50 can be installed on both the trailing and leading ends of the rail R. In addition, the inner block 50 may be installed in the upper rail R of the sliding door D, or it may be installed in the lower rail R of the sliding door D. In this case, the design can be modified to allow installation in the lower rail R.

[0035] The configuration of the sliding door device 60 described in this embodiment is just one example, and the configuration of the sliding door device 60 of the present invention is not limited to the configuration of the above embodiment. The sliding door device 60 of the present invention can be modified by omitting, replacing, adding, or otherwise altering its configuration without changing its essence.

[0036] (operation) Finally, the operation of the sliding door device 60 using the inner block 50 of the present invention will be described. Here, the explanation will be divided into two cases: when closing the sliding door D while it is held by the catch portion 22b of the inner block 50, and when opening the closed sliding door D and holding it with the catch portion 22b.

[0037] When closing the sliding door D, which is held in place by the catch portion 22b of the inner block 50, moving the sliding door D in the closing direction (direction of the X arrow in the figure) from the state shown in Figure 7(a) causes the locking projection 22c to contact the inner surface of the locking recess 41a and rotate, pushing it upward, as shown in Figure 7(b). Moving the sliding door D further in the same direction from that state causes the locking projection 22c to disengage from the locking recess 41a, as shown in Figure 7(c), releasing the sliding door D from being held and allowing it to be moved to the fully open position.

[0038] On the other hand, when closing the open sliding door D, as shown in Figure 8(a), when the sliding door D is moved in the closing direction (direction of the Y arrow in the figure) from the state where the leading edge of the sliding door D reaches the position of the inner block 50, the suspension wheel 41 comes into contact with the catch part 22b as shown in Figure 8(b), causing the catch part 22b to rotate and be pushed upward. If the sliding door D is moved further in the same direction from that state, as shown in Figure 8(c), the leading edge end face of the sliding door D abuts against the contact surface 16 and stops, and the locking projection 22c of the catch part 22b fits into the locking recess 41a, holding the sliding door D in the predetermined position. [Industrial applicability]

[0039] The inner block 50 of the present invention can be used as an inner block 50 with or without a catch for various sliding doors. The sliding door device 60 of the present invention can be used in various places where sliding doors are installed, including detached houses and apartment buildings. [Explanation of Symbols]
