[0011] (Embodiment of 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 ease of explanation, in the following description, the sliding door D is used as the reference, and the upper side is referred to as the upper side, the lower side as the lower side, the door leading edge side as the front side, the door trailing edge side as the rear side, the left side in the sliding door closing direction as the left side, and the right side as the right side.

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

[0013] The door stop body 10 is a member against which the sliding door D abuts. As shown in Fig. 1(b), the door stop body 10 of this embodiment is in the shape of a square block, and includes a first mounting portion 11 on which the sliding door holder 20 is placed, a second mounting portion 12 that is one step higher than the first mounting portion 11, and two support posts 13 that protrude upward from the second mounting portion 12.

[0014] The door stop body 10 is provided with a door stop body side locking portion 14 that locks the sliding door holder 20. In this embodiment, the door stop body side locking portion 14 comprises peripheral surface locking portions 14a provided on the left and right peripheral surfaces of the second mounting portion 12, and rear surface locking portions 14b provided on the rear surfaces of the two support pillars 13.

[0015] The first mounting portion 11 and the second mounting portion 12 are provided with screw holes 15 that penetrate in the thickness direction (vertical direction). These screw holes 15 are for inserting screws 30 that are used to fix the door stop body 10 inside the rail R.

[0016] The two support pillars 13 are spaced apart from each other by a distance large enough to accommodate a catch portion 22b (described later) of the sliding door holder 20. In this embodiment, the support pillars 13 are triangular prisms in plan view, and a curved recess is formed on the inner surface of each support pillar 13.

[0017] The door stop body 10 is provided with a flat contact surface 16 against which the sliding door D comes into contact. Although not shown in the figure, a cushioning material such as a rubber pad or a silicone pad can be provided on the contact surface 16. By providing a cushioning material, it is expected that the impact noise between the sliding door D and the door stop body 10 can be reduced and damage to the door stop body 10 can be prevented.

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

[0019] The lower structure 21 of this embodiment has two locking arms 21a spaced apart from each other. The two locking arms 21a are sized and shaped so that they can be placed on the first placement section 11, and the free ends of both locking arms 21a are provided with holder-side locking sections 21b that lock onto the rear surface locking sections 14b.

[0020] An insertion hole 22a is provided in the upper structural portion 22, penetrating in the thickness direction. This insertion hole 22a is a through hole for passing a screw 30 therethrough, and is sized so that the screw 30 does not come into contact with the inner peripheral 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. A locking projection 22c that is triangular in side view is provided on the catch portion 22b. This locking projection 22c is a portion that locks into a locking recess 41a formed in a hoist 41, which is one component of the hoist unit 40 (FIGS. 6(a) and 6(b)).

[0022] In this embodiment, by engaging the door stop body side locking portion 14 with the holder side locking portion 21b while the sliding door holder 20 is placed on the door stop body 10, the sliding door holder 20 is prevented from coming off in the vertical direction without using any fasteners such as setscrews. Note that the catch portion 22b of the sliding door holder 20 held by the door stop body 10 moves up and down (rotates in the direction toward and away from the hoist 41) when it is engaged with the locking recess 41a.

[0023] The inner block 50 of this embodiment is used by being fixed inside the rail R along which the hoist 41 attached to the sliding door D runs. Specifically, the inner block 50 is fixed to the rail R by inserting and screwing the screw 30 from below into the screw hole 15 of the door stop body 10 on which the sliding door holder 20 is placed, 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 an external appearance as shown in Figures 3(a) to 3(f). Figure 3(a) is a front view of the inner block 50 in Figure 1(a), (b) is a rear view of (a), (c) is a left side view of (a), (d) is a right side view of (a), (e) is a plan view of (a), and (f) is a bottom view of (a).

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

[0026] Even when the door stop body 10 is used alone, the door stop body 10 can be fixed to the rail R by inserting and screwing a screw 30 from the underside of the screw hole 15 of the door stop body 10 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 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, such as by omitting, replacing, or adding components, as long as the gist of the inner block 50 is not changed.

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

[0029] As an example, a sliding door device 60 shown in Fig. 5 includes a sliding door D equipped with a hoist unit 40 on the top, a rail R along which the sliding door D runs, and an inner block 50 attached (fixed) to the inside of the rail R. The sliding door D, the hoist unit 40, and the rail R can be either existing or new.

[0030] As an example, the hoist unit 40 shown in Figures 6(a) and (b) was previously developed by the applicant of the present application, and as shown in Figures 6(a) and (b), it comprises a hoist 41, a case 42, a bounce prevention device 43, a vertical position adjustment device 44, a horizontal position adjustment device 45, a connecting device 46, a stopper 47, a front cover 48, and a case holder 49.

[0031] In the hoist unit 40 of this embodiment, the bounce prevention device 43 is located in front of the connecting device 46, so the sliding door D cannot be held in any position by a sliding door holder of the type that holds the sliding door D by pressing down on the upper side of the wheel, or a sliding door holder of the type that holds the sliding door D by clamping the connecting shaft.

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

[0033] (Other embodiments of the sliding door device) In the above embodiment, the case where the inner block 50 is provided at a position on the door trailing side of the rail R is taken as an example, but in the sliding door device 60 of the present invention, the inner block 50 can also be provided at a position on the door leading side of the rail R. In this case, by holding the closed sliding door D with the catch portion 22b, it is possible to prevent the sliding door D from opening unintentionally.

[0034] The inner block 50 can also be provided on both the trailing edge and leading edge of the rail R. In addition, the inner block 50 can be installed inside the rail R at the top of the sliding door D, or it can be installed on the rail R at the bottom of the sliding door D. In this case, the design can be modified so that it can be installed on the lower rail R.

[0035] The configuration of the sliding door device 60 described in this embodiment is 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, such as by omitting, replacing, or adding components, within the scope that does not change the gist of the invention.

[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 operation will be described separately for the case where the sliding door D is closed while being held by the catch portion 22b of the inner block 50, and the case where the sliding door D is opened while being closed and held by the catch portion 22b.

[0037] When closing the sliding door D held by the catch portion 22b of the inner block 50, if the sliding door D is moved in the closing direction (the direction of the X arrow in the figure) from the state shown in Fig. 7(a), the locking protrusion 22c will come into contact with the inner surface of the locking recess 41a, rotate, and be pushed upward, as shown in Fig. 7(b). If the sliding door D is further moved in the same direction from that state, the locking protrusion 22c will come out of the locking recess 41a, as shown in Fig. 7(c), and the holding of the sliding door D will be released, allowing it to be moved to the fully open position.

[0038] On the other hand, when closing the sliding door D in an open state, when the sliding door D is moved in the closing direction (direction of arrow Y in the figure) from a state in which the door tip side of the sliding door D has reached the position of the inner block 50 as shown in Fig. 8(a), the hoist 41 comes into contact with the catch portion 22b as shown in Fig. 8(b), causing the catch portion 22b to rotate and be pushed upward. When the sliding door D is further moved in the same direction from that state, the end face of the door tip side of the sliding door D hits the contact surface 16 and stops as shown in Fig. 8(c), and the locking protrusion 22c of the catch portion 22b fits into the locking recess 41a, holding the sliding door D in a 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 any location where a sliding door is installed, including detached houses and apartment buildings. [Explanation of symbols]
