The self-closing sliding door device 100 according to this embodiment is capable of self-closing an upper suspension type sliding door device whose upper part is suspended by a runner member and whose lower part is guided, and the self-closing sliding door unit 150 drives the sliding door. Unit.
[0040]
The self-closing sliding door device 100 is mainly composed of a sliding door 1, a self-closing sliding door unit 150, an upper rail 2, a runner member 3, and a lower guide 6.
[0041]
The self-closing sliding door unit 150 is attached between the upper end surface 11 and the upper collar surface U of the sliding door 1 and is for self-closing the sliding door 1 from the open position to the closed position, and is fixed to the rail 2. It consists of a rack sheet 4 and a drive unit 5.
[0042]
The rack seat 4 is in the form of a sheet and extends along the outer side 22 of the running surface 21 of the rail 2, and at the same time the surface extends from a substantially central position A1 when the sliding door 1 is fully closed to at least an intermediate portion A in the length direction of the rail 2. The gear mechanism 41 has a gear surface 41 and is combined with the gear mechanism 51 to rotate the gear mechanism 51. A double-sided sheet is laid on the back surface 42 of the rack sheet 4, and the rack sheet 4 is fixed to the outer side 22 of the running surface 21 of the rail 2. The rack sheet 4 may be fixed with screws or an adhesive.
[0043]
The drive unit 5 has a gear mechanism 51 that is engaged with the gear surface 41 of the rack seat 4, and is embedded in the upper end surface of the substantially center of the door plate in the opening / closing direction of the sliding door 1. The drive unit 5 includes a drive mechanism 52 that applies a drive force to the gear mechanism 51 from the release position of the sliding door 1 toward the closed position.
The drive unit 5 is surrounded by a housing 53 attached to the upper end surface 11. Therefore, the gear mechanism 51 is built in the housing 53 and rotates as the sliding door 1 is opened.
[0044]
The drive mechanism 52 includes a spring mechanism 52 a that accumulates a spring force by rotation and a damper 52 b that adjusts the release of the spring force of the spring mechanism 52 a. The drive mechanism 52 is built in the housing 53 and built in the drive unit 5. . A spring is usually used as the spring mechanism 52a. However, the spring mechanism 52a is not limited to a spring, and any mechanism that accumulates a spring force by rotation may be used.
[0045]
The housing 53 is formed in a narrow width that can be embedded in the upper end surface 11 of the sliding door 1, is located on the gear mechanism 51 side, and a washer 531 extends from the housing 53.
[0046]
The rail 2 is provided with a pair of running surfaces 22 that are fixed to the upper collar surface U or the like and are opposed to each other in a substantially L shape below, and the rack seat 4 extends along the outer side 22 of the running surface 21 of the rail 2. Is provided. The rail 2 may be provided in a carved rail groove.
[0047]
The sliding door 1 is a top-hanging type sliding door, and an insertion hole 12 for incorporating the drive unit 5 is dug into the upper end surface 11 at the substantially center of the door plate in the opening / closing direction of the sliding door 1.
[0048]
The runner member 3 travels on the traveling surface 21 of the rail 2, and two runner members 3 are provided on the upper end surface 11 of the sliding door 1 to suspend the sliding door 1. Further, the lower guide 6 is fixed to the floor surface F in the vicinity of the door bottom 13 of the sliding door 1 and engages with a guide groove 61 in the lower part of the sliding door to prevent the sliding door 1 from swinging.
[0049]
The attachment of the self-closing sliding door device 100 having the above configuration will be described below.
[0050]
First, the sliding door 1 is removed leaving the runner member 3 in the rail 2 from the existing sliding door. Then, along the outer side 22 of the running surface 21 of the rail 2, the rack seat 4 is fixed from the substantially central position A1 when the sliding door 1 is fully closed to at least the middle portion A in the length direction of the rail 2 (up to the A1 position). Let
[0051]
Then, the sliding door 1 to which the self-closing sliding door unit 150 is attached in advance is brought close, and the gear mechanism 51 of the drive unit 5 is attached to the gear surface 41 of the rack seat 4 while meshing. Here, the mounting position of the sliding door 1 is set to a fully closed state, and when the driving mechanism 52 of the driving unit 5, that is, the spring mechanism 52 a opens the sliding door 1, the spring force can be accumulated by rotation.
[0052]
Further, when the meshing of the gear surface 41 of the rack seat 4 and the gear of the gear mechanism 51 is insufficient with the sliding door 1 attached (less meshing or too tight meshing), the vertical adjustment mechanism of the runner member 3 23, adjustment is performed so that optimum meshing is possible.
[0053]
In addition, since the drive unit 5 has a structure that can be retrofitted by adding an existing sliding door, the existing sliding door is remodeled (the insertion hole 12 is dug) and the drive unit 5 is attached. It is also possible.
[0054]
Next, the operation of the self-closing sliding door device 100 and the self-closing sliding door unit 150 will be described below.
[0055]
When the sliding door 1 is moved from the release position toward the closed position, the gear mechanism 51 of the drive unit 5 engages with the gear surface 41 of the rack seat 4 fixed to the rail 2 in synchronization with the movement of the sliding door 1 and rotates. To do.
The rotation of the gear mechanism 51 is transmitted to the drive mechanism 52, and the spring force is accumulated in the spring mechanism 52a. Specifically, the spring of the spring mechanism 52a is wound. Note that the maximum spring force is accumulated at the position where the sliding door 1 is in the previous state. At this time, the drive unit 5 moves from the position A1 in the fully closed state of the sliding door 1 to the position A2 in the fully open state. A stopper (not shown) is provided so that the drive unit 5 cannot move any more when the drive unit 5 reaches the position A2, so that the drive mechanism 52 does not disengage from the rack seat 4.

Next, when the hand is released from the sliding door 1, the sliding door 1 moves the gear mechanism 51 into the rack seat by the driving force (spring force accumulated in the spring mechanism 52 a) applied to the driving mechanism 52 from the open position toward the closed position. It rotates on 41 and comes to self-close. At that time, since the release of the spring force is adjusted by the damper 52b, the moving speed of the sliding door 1 is suppressed, and the sliding door 1 can move toward the closed position. An initial load is applied to the drive mechanism 52 at the closed position of the sliding door 1 so that the drive mechanism 52 can be surely self-closed.
[0057]
According to this embodiment (1), in the upper suspension type sliding door device, the sheet-like rack seat 4 is fixed to the surface of the rail 2 along the outer side of the upper rail 2, and the gear mechanism 51 is engaged with the rack. The drive unit 5 from which the protrusion is protruded is embedded in the upper end surface 11 of the door plate, and since the drive unit 52 has a built-in drive mechanism 52 for applying a drive force to the gear mechanism 51, the upper runner member 3 is affected. The rack seat 4 can be attached without any problems. Thus, the existing runner member 3 can be used as it is, and the upper end portion 11 of the sliding door 1 can be modified to make a self-closing sliding door, which can be an inexpensive self-closing sliding door device and a self-closing sliding door unit.
[0058]
Further, by remodeling the upper end surface of the sliding door and embedding the drive unit 5, it is possible to hide the gear mechanism 51 other than the protruding gear mechanism 51 and to obtain a self-closing type sliding door device and a self-closing sliding door unit that do not impair the appearance. It is done.
[0059]
5 to 6 show an embodiment (2) of the present invention.
[0060]
The self-closing sliding door device 200 according to this embodiment is configured such that a lower load type sliding door device whose lower portion is supported by a runner member and whose upper portion is guided can be self-closed. This is a drive unit. Therefore, although the support method of the sliding door 1 differs from Embodiment (1), the self-closing sliding door unit 150 can use the same thing.
[0061]
The self-closing type sliding door device 200 is mainly composed of a sliding door 1, a self-closing sliding door unit 150, an upper guide rail 202, and a lower runner member 203.

[0066]
7 to 8 show an embodiment (3) of the present invention.
[0067]
The self-closing sliding door device 300 in this embodiment is obtained by changing the gear mechanism 51 of the embodiment (2) to a friction wheel mechanism 351 and eliminating a rack.
[0068]
The friction wheel mechanism 351 is in direct contact with the inner lower surface 202a of the upper guide rail 202 to be frictionally engaged. Therefore, it is desirable to select a material having a high coefficient of friction between the guide rail 202 and the friction wheel mechanism 351. Alternatively, it is also effective to attach a liner that increases the coefficient of friction to the guide rail 202 and the friction surface 301 of the friction wheel mechanism 351.
[0069]
In order to transmit the driving force to the damper 52b by using the friction wheel mechanism 351, a small gear 351a for driving the damper 52b needs to be connected to the friction wheel mechanism 351.
[0070]
The drive unit 5 uses a spring mechanism 52a as the drive mechanism 52 shown in the embodiment (1).
[0071]

[0073]
FIG. 9 shows an embodiment (4) of the present invention.
[0074]
In this embodiment, the drive unit 5 of the embodiments (1) to (3) is changed.
[0075]
That is, the motor 52M is used as the drive mechanism 52. The motor 52M and the gear mechanism 51 are connected by a belt 54, and the gear mechanism 51 is driven. In this case, since the motor 52M can perform self-closing speed control, the damper 52b is omitted. In addition, a control mechanism (not shown) such as a simple microcomputer is provided. The motor 52M is fixed to the housing 53 by a pedestal 55.
[0076]
For example, when the drive mechanism 52 by the motor 52M is applied to the drive mechanism 52 of the embodiment (1), when the sliding door 1 is opened, the rotation speed of the gear mechanism 51 rotated is stored in the microcomputer and stored in the self-closing operation. The motor is rotated by the number of rotations, and the gear mechanism 51 moves on the rack seat 4 to move the sliding door 1 in the closing direction.
[0077]
According to this embodiment (4), in addition to the effects and effects similar to those of the embodiment (1), since the motor 52M is used as the drive mechanism 52, the damper 52b can be omitted. At the same time, self-closing speed control can be easily performed with a microcomputer or the like.

[0083]
According to the self-closing type sliding door device 400 of this embodiment, in the lower load type sliding door device, the sliding door self-closing unit 150 is attached to the lower portion, and the same operations and effects as in the embodiment (1) are exhibited. Therefore, the upper end surface of the sliding door 1 can be made free and another device can be incorporated.
[0084]
Although not shown, it is possible to attach the housing 53 of the drive unit 5 to the flange surface U of the sliding door 1. In this case, the mounting position of the housing 53 is on the door bottom 13 side, and the rack is mounted over substantially the entire width of the end surface of the sliding door 1. This form is possible in the upper part for the embodiments (2) and (3), and is possible in the lower part for the embodiments (1) and (4).
[0085]
Further, although common to the embodiments other than the embodiment (4), a bidirectional clutch (not shown) may be provided in addition to the damper 52b. This bi-directional clutch reverses the characteristics of the clutch when a force exceeding a certain level is applied. When the sliding door is stopped at a predetermined position, the bi-directional clutch can be operated and held at that position. .
