Description

The present invention relates to an inner block for a sliding door and a sliding door device using the inner block.

The running rail for the sliding door may be provided with a door stop to block the sliding door at any position, or a catch to hold the sliding door in any position.

A known component used in this type of application is a stopper (Patent Document 1) equipped with an elastic retaining member (catch) that elastically contacts the circumferential surface of the hoist to hold the hoist in the open or closed position.

Japanese Patent Application Publication No. 9-189168

The stopper in Patent Document 1 has the drawback of being time-consuming to assemble, as the main elastic piece and the secondary elastic piece must be fastened to the fixing parts with screws when in use.

The present invention was made in light of these circumstances, and its goal is to provide an inner block that requires less assembly time than conventional stoppers, and a sliding door device that uses this inner block.

[Inner block]
The inner block of the present invention is an inner block that is installed within a rail along which a sliding door hoist runs, and includes a door stop body against which the sliding door abuts and a sliding door holder that holds the sliding door. The door stop body has an abutment surface that abuts the hoist and a door stop body-side locking portion that locks the sliding door holder, and the sliding door holder has a holder-side locking portion that locks with the door stop body-side locking portion and a catch portion that locks with the hoist, and is configured so that when the sliding door holder is placed on the door stop body, the door stop body-side locking portion and the holder-side locking portion lock together, preventing the sliding door holder from coming loose in the vertical direction without the use of a stopper.

[Sliding door device]
The sliding door device of the present invention is a sliding door device comprising a sliding door equipped with a hoist unit on the top of the sliding door, a rail along which the hoist of the hoist unit equipped on the sliding door runs, and an inner block fixed within the rail, with the inner block of the present invention mounted within the rail.

The inner block and sliding door device of the present invention can be assembled simply by engaging the retainer-side locking portion with the door stopper-side locking portion, making assembly less time-consuming than conventional stoppers.

(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 ease of explanation, in the following description, the sliding door D is used as a 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.

The inner block 50 of the present invention is installed within the rail R on which the hoist 41 (Fig. 2(b)) for the 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.

The door stop body 10 is the component against which the sliding door D abuts. As shown in Figure 1(b), the door stop body 10 in this embodiment is a square block, and includes a first mounting portion 11 on which the sliding door holder 20 rests, 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.

The door stop body 10 is provided with door stop body side locking portions 14 that lock the sliding door holder 20. In this embodiment, the door stop body side locking portions 14 include peripheral locking portions 14a provided on the left and right peripheral surfaces of the second mounting portion 12, and rear locking portions 14b provided on the rear sides of the two support posts 13.

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

The two support pillars 13 are spaced apart. This space is wide enough to accommodate the catch portion 22b (described below) 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.

The door stop body 10 has a flat contact surface 16 against which the sliding door D contacts. Although not shown in the figure, the contact surface 16 can also be provided with a cushioning material such as a rubber pad or silicone pad. 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.

The sliding door holder 20 is a component that holds the sliding door D at any position within the rail R. As shown in Figure 1(b), the sliding door holder 20 in this embodiment is a U-shaped component in side view, integrally formed with a lower structure 21 that rests on the first mounting section 11 and an upper structure 22 that rests on the second mounting section 12.

In this embodiment, the lower structure 21 has two locking arms 21a spaced apart. The two locking arms 21a are sized and shaped so that they can be placed on the first mounting 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.

The upper structural portion 22 has an insertion hole 22a that penetrates through the thickness of the wall. 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 peripheral surface after passing through.

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

In this embodiment, when the sliding door holder 20 is placed on the door stop body 10, the door stop body side locking portion 14 and the holder side locking portion 21b are locked together, preventing the sliding door holder 20 from coming loose in the vertical direction without the need for fasteners such as setscrews. Furthermore, the catch portion 22b of the sliding door holder 20 held by the door stop body 10 moves up and down (rotates toward and away from the hoist 41) when locked into the locking recess 41a.

The inner block 50 in this embodiment is fixed to 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 a 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 top surface of the rail R.

The inner block 50 configured as described above has the external appearance shown in Figures 3(a) to (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).

(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).

When using the door stop body 10 alone, the door stop body 10 can be fixed to the rail R by inserting and screwing the screw 30 into the lower side of the screw hole 15 of the door stop body 10 and pressing the tip of the screw 30 against the top surface of the rail R.

The configuration of the inner block 50 described in this embodiment is an 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.

(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-described embodiment is used will be taken as an example. Since the inner block 50 has already been described, its description will be omitted here.

As an example, the sliding door device 60 shown in Figure 5 comprises a sliding door D with a hoist unit 40 attached to the top, a rail R along which the sliding door D runs, and an inner block 50 attached (fixed) to the rail R. The sliding door D, hoist unit 40, and rail R can be either existing or new.

As an example, the hoist unit 40 shown in Figures 6(a) and (b) was previously developed by the present applicant, 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.

In this embodiment of the hoist unit 40, 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 with a sliding door holder that holds the sliding door D by pressing down on the upper side of the wheel, or a sliding door holder that holds the sliding door D by clamping the connecting shaft.

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 top surface of the hoist 41, so the sliding door D can be held in any position.

(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.

The inner block 50 can also be installed on both the trailing and leading sides of the rail R. Additionally, the inner block 50 can be installed within the upper rail R of the sliding door D, or it can be installed on the lower rail R of the sliding door D. In this case, the design can be modified so that it can be installed on the lower rail R.

The configuration of the sliding door device 60 described in this embodiment is an 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, as long as the gist of the device is not changed.

(operation)
Finally, the operation of the sliding door device 60 using the inner block 50 of the present invention will be described below. 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.

When closing the sliding door D while it is held by the catch portion 22b of the inner block 50, if the sliding door D is moved in the closing direction (direction of the X arrow in the figure) from the state shown in Figure 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 Figure 7(b). If the sliding door D is moved further in the same direction from this state, the locking protrusion 22c will disengage from the locking recess 41a, as shown in Figure 7(c), and the sliding door D will be released and can be moved to the fully open position.

On the other hand, when closing the sliding door D in an open state, as shown in Figure 8(a), when the door edge of the sliding door D reaches the position of the inner block 50, the sliding door D is moved in the closing direction (direction of the Y arrow in the figure), and as shown in Figure 8(b), the hoist 41 abuts against the catch portion 22b, causing the catch portion 22b to rotate and be pushed upward. If the sliding door D is then moved further in the same direction, the end face of the door edge of the sliding door D abuts against the abutment surface 16 and stops, as shown in Figure 8(c), and the locking protrusion 22c of the catch portion 22b fits into the locking recess 41a, holding the sliding door D in the specified position.

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.
