Abstract

PURPOSE:To make it possible to open and close more smoothly by engaging a control gear body provided with a two-way engagement clutch with a wheel drive gear or the like capable of moving a sliding door which is installed to a rail in a suspended state and protecting a clutch from being affected by the load of a door. CONSTITUTION:A control gear body 9, which incorporates a two-way engagement clutch mechanism 12 capable of halting temporarily a movable body 1 at an arbitrary position and preventing its reverse mobile motion within a specified torque, is engaged with a gear body 8 which drives a wheel 6 which suspends the movable body 1 of a heavy sliding door or a door. The whole load of the movable body 1 installed on a rail in a suspended state is received with the wheel 6 in such a fashion that no entire load of the movable body may be applied on the clutch mechanism 12 of the control gear body 9. This construction makes it possible to keep not only the movable body 1 in an engaged state at an arbitrary position, but also open and close more smoothly.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bidirectional locking clutch mechanism capable of temporarily stopping the movement of a movable body such as a heavy sliding door or door at an arbitrary position and preventing the movement in the opposite direction within a predetermined torque. The present invention relates to a control device incorporated in a movable body.

[0002]

2. Description of the Related Art Conventionally, movable movable bodies, for example, sliding doors used for entrances and exits of general houses, offices, warehouses, etc., are mounted so that a door roller can be rotatably moved on a rail provided along the opening / closing direction of the sliding door. The structure is such that the sliding door can be operated smoothly. However, for example, due to the rail being slightly inclined, the door roller may naturally rotate and move in the closing direction or the opening direction during the opening / closing operation of the sliding door. In order to solve this, the applicant of the present invention first disclosed in Japanese Patent Laid-Open No.
As disclosed in Japanese Laid-Open Patent Publication No. 17693, a sliding door having a bidirectional locking clutch mechanism incorporated in a door roller that can temporarily stop the sliding door at an arbitrary position during opening / closing operation and prevent movement in the reverse direction within a predetermined torque is developed. However, the predetermined effect could be achieved.

[0003]

However, in this prior art, since the bidirectional locking clutch mechanism is incorporated in the door roller traveling on the rail, it must be incorporated in a limited door roller. Especially, when it is installed in a heavy sliding door, the bearing portion may not be durable and may be buckled. Therefore, the present invention has been made in view of the above-mentioned problems of the conventional technology and the prior art, and is made in order to solve this problem, and a movable body such as a heavy sliding door and a door can be completely moved, An object of the present invention is to provide a controller for a rotating member equipped with a two-way locking clutch mechanism that is robust and has excellent durability so that it can be reliably stopped at any position even during its operation.

[0004]

As a means for solving the above problems, the present invention rotatably pivotally mounts a rotating member on a movable body and enables rotation of a control gear body incorporating a bidirectional locking clutch mechanism. The control gear body is engaged with the gear formed on the outer ring portion of the rotary member, and the bidirectional locking clutch mechanism in the control gear body temporarily stops the movable body that is movable via the rotary member at an arbitrary position. However, the movement in the opposite direction is controlled so as to be blocked within a predetermined torque.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention shown in the drawings will be described in detail below. 1 to 6 show a first embodiment of the present invention implemented in a large and heavy sliding door that opens and closes an entrance / exit. A sliding door 1 formed of a large and heavy movable body is mounted on a rail C which is installed on the upper wall portion B of the doorway A by a door roller 3 attached thereto so as to be gradually inclined toward the closing direction. It is rotatably suspended and can be opened and closed. A door wheel 3 as a rotating member has a main shaft 4 fixed to a mounting bracket 2 mounted on an upper frame of a sliding door 1, and a main shaft 4 is rotatably mounted with an outer ring body 6 via a ball bearing bearing 5 and attached to an outer ring body 6. A rail engaging groove 7 that engages with the rail C is formed, and gear portions 8 are formed on both sides of the rail engaging groove 7. In the control gear body 9, a bidirectional locking clutch mechanism 12 is incorporated between a support shaft 10 and an outer ring gear part 11 to rotatably control the outer ring gear part 11 so that the outer ring gear part 11 is a gear part of the door roller 3. 8
The support shaft 10 is fixed to the mounting bracket 2 of the sliding door 1 so as to mesh with. The bidirectional locking clutch mechanism 12 is basically the same as the bidirectional locking clutch disclosed in Japanese Patent Laid-Open No. 4-17693 of the above-mentioned prior art,
This will be described in more detail. As shown in FIGS. 4 to 6, the bidirectional locking clutch mechanism 12 is used for the outer ring gear unit 1
1, a control plate 14, a rotation holding body 15, a receiving ring 1 around the support shaft 10 in an inner cylindrical body 13 which is non-rotatably fitted.
6, members including roller pins 17 and elastic wires 18 are incorporated. The outer ring gear unit 11 has a wall surface 11a on one side.
Thus, the other side is formed into a cylindrical shape having an opening 11b. Then, the support shaft 10 is inserted into the through hole 11c formed in the wall surface 11a, and the support shaft 10 is inserted into the bearing ring 21 fitted in the fitting recess 11d formed on the outer peripheral surface thereof. The inner cylindrical body 13 is
One side is a wall surface 13a, and the other side is formed in a cylindrical shape having an opening 13b. The wall surface 13a is provided with a through hole 13c through which the support shaft 10 is inserted. The bearing ring 21 fitted to the support shaft 10 cannot rotate the inner cylindrical body 13 into the outer ring gear portion 11 via the washer 22. To fit. The control plate 14 is formed in a substantially annular shape in which a through hole 14a for inserting the support shaft 10 is formed, and concave grooves 14b are cut out at predetermined positions on the inner peripheral surface of the through hole 14a, that is, three positions in this embodiment. ing. The recessed groove 14b has the shallowest portion 14c at the center and the retreat groove portions 14d and 14d are formed in a substantially shape such that both sides thereof are deep. The outer peripheral portion is also made of a thin plate material in which a substantially circular arc-shaped floating notch 14e is formed toward the concave groove 14b. On both sides, they are non-rotatably fitted in the inner cylindrical body 13 so as to sandwich them. The rotary holder 15 has a through hole 15a formed in the center thereof for inserting the support shaft 10, and an inner peripheral surface of the through hole 15a corresponding to the concave groove 14a of the control plate 14.
A holding groove 15b for supporting a roller pin narrower than the concave groove 14a is formed at a position, and a wire rod fitting groove 15c for inserting the elastic wire rod 18 at a position corresponding to the holding groove 45b is formed on the outer peripheral portion. It has been cut out. The receiving ring 16 is fitted into the rotation holding body 15 and is fitted together with the rotation holding body 15 in the inner cylindrical body 13 so as to be rotatable. The roller pin 17 is
It is inserted over the outer peripheral surface of the support shaft 10, the concave groove 14b of the control plate 14, and the space portion formed in the holding groove 15b of the rotary holding body 15. The elastic wire rod 18 is inserted into the free cutout portion 14e of the control plate 14 and the wire rod fitting groove 15c of the rotation holding body 15, and one end thereof is inserted into a small hole 13d formed in the wall surface 13a of the inner cylindrical body 13. Then, the other end is inserted and locked in a small hole 19b formed in a holding plate 19 tightly fitted into the opening 13b of the inner cylindrical body 13 in a non-rotatable manner. Then, the support shaft 10 is passed through the through hole 19a of the pressing plate 19, and the bearing ring 21 is fitted to the support shaft 10 via the washer 22. 20 b, and the support shaft 10 is inserted into the through hole 20 a formed in the bearing cover plate 20 to insert the bearing cover plate 20 into the opening 11 b of the outer ring gear 11.
The two-way locking clutch mechanism 12 is assembled by tightly fitting.

Since it is constructed in this way, the sliding door 1
When the door roller 3 is moved in the opening direction, the rail engaging groove 7 of the outer ring body 6 rotates clockwise on the rail C as shown in FIG. The sliding door 1 receives the entire weight of the sliding door 1 via the bearing 5 and operates robustly and smoothly, so that the sliding door 1 can travel lightly. At the same time, the outer ring body 6 of the door roller 3 has its gear portion 8
Engage with the control gear body 9, the control gear body 9 is rotated counterclockwise as shown in FIG. As a result, the bidirectional locking clutch mechanism 12 incorporated in the outer ring gear portion 11 operates, and accordingly, as shown in FIG.
Since the control plate 14 in 3 is rotated counterclockwise, the roller pin 17 positioned in the central shallowest portion 14c of the concave groove 14b formed in the control plate 14 is located on the right side as shown in FIG. The elastic wire 18 moves to the retreat groove portion 14d at that time.
Is curved in the clockwise direction against the elasticity by the rotation of the control gear body 9. The center portion of the elastic wire rod 18 is inserted and held in the wire rod fitting groove 15c of the rotary holding body 15, while the inner cylinder body 13 and the holding plate 19 which hold both ends are controlled by the control gear. When the body 9 is rotated counterclockwise, it is curved in an arcuate shape against its elasticity, so that the roller pin 17 is always kept in the state in which the counterclockwise elastic force acts on the rotation holding body 15. As long as the control gear body 9 continues to rotate in the counterclockwise direction, it moves to the evacuation groove portion 14d on the right side and keeps the free state, whereby the bidirectional locking clutch 12 becomes the non-locking state with respect to the support shaft 10. The periphery of the support shaft 10 can be freely rotated together with the outer ring gear portion 11, and the sliding door 1 can be moved in the opening direction lightly. When the sliding door 1 is completely opened or the opening operation is stopped halfway, the rail C is inclined in the closing direction, so that the sliding door 1 is given a predetermined torque in the closing direction, and the door roller 3 is Contrary to the above, since it tries to rotate in the counterclockwise direction, a clockwise rotational force acts on the control gear body 9 which interlocks with this, and the bidirectional locking clutch mechanism 12 incorporated in the outer ring gear portion 11 is engaged.
The control plate 14 in the inner cylindrical body 13 rotates in the clockwise direction in response to this, and as shown in FIG. 5, the control plate 14 is positioned in the free groove 14d on the right side of the concave groove 14b of the control plate 14 in the free state. The roller pin 17 tries to move in the direction of the central shallowest portion 14c of the concave groove 14b, and at the same time, the elastic restoring force of the elastic wire 18 curved in an arc also causes the rotation holding body 15 to rotate in the counterclockwise direction. Then, the control gear body 9 is pushed back to the central shallowest portion 14c to be in the locked state as shown in FIG. 4, and the control gear body 9 is stopped, and the rotation of the door roller 3 meshing with the control gear body 9 is stopped. As a result, the sliding door 1 does not return in the closing direction and is in an open state at the fully open position or an arbitrary stop position, and the sliding door 1 is easily closed even if an unexpected external force such as vibration is applied. There is no such thing. Further, when a torque of a predetermined value or more is applied in this state in the closing direction, the control gear body 9 is passed through the door roller 3.
Rotates in the clockwise direction and the bidirectional locking clutch mechanism 12 operates, and accordingly, the control plate 14 in the inner cylindrical body 13 rotates in the clockwise direction, so that as shown in FIG. The roller pin 17 pushed back to the central shallowest portion 14c and in the locked state moves to the retracted groove portion 14d on the left side to keep the free state, whereby the two-way locking clutch 12 with respect to the support shaft 10. In the non-locking state, the periphery of the support shaft 10 can freely rotate together with the outer ring gear portion 11, and the sliding door 1 can travel in the closing direction lightly. After closing, the two-way locking clutch mechanism 12 causes the roller pin 17 to have the shallowest portion 14c at the center of the roller pin 14b by only applying a slight torque in the opening direction, which is the reverse of the above.
Since it is locked at, the stopping force will be applied. Therefore, even if an unexpected external force such as vibration is applied in the opening direction, the sliding door 1 will not be easily opened. It is needless to say that when the sliding door is opened against the stopping force, the position of the roller pin 17 is moved to the retracting groove portion 14d position and the opening operation can be performed again if a torque to release the stopping force is applied. Yes.

FIGS. 7 and 8 show a second embodiment implemented on a heavy door attached to the underfloor storage section. The door 30 made of a heavy movable body has a main shaft 3 on each side wall 30a.
1 is fixed by welding. The main shaft 31, which is a rotating member, is rotatably attached to mounting plates 33 and 34, which are fixed to both sides of a frame 32 attached to the upper end opening of the underfloor storage chamber D, to open and close the underfloor storage chamber D. A gear 31a is integrally fixed to the main shaft 31 pivotally attached to at least one mounting plate 33. In the control gear body 35, the bidirectional locking clutch mechanism 38 is incorporated between the support shaft 36 and the outer ring gear part 37, and the outer ring gear part 37.
Is rotatably controlled, and its support shaft 36 is fixed to the mounting plate 33. The bidirectional locking clutch mechanism 38 is similar to that of the first embodiment.

With this structure, in order to open the underfloor storage room D, when the door 30 is rotated in the opening direction around the main shaft 31, the main shaft 31 receives the entire weight of the door 30 and is robust. It operates smoothly, the door 30 can be rotated smoothly, and the gear 31a integral with the main shaft 31 meshes with the outer ring gear portion 37 of the control gear body 35.
The two-way locking clutch mechanism 38 incorporated between the door 30 and the door operates in the same manner as in the first embodiment, and the door 30 is freed.
Can be freely rotated in the opening direction and the door 3
0 can be rotated to the fully open position. However, if the operation in the opening direction is stopped midway, the bidirectional locking clutch mechanism 38 enters the locked state and is locked when it receives the rotational force in the reverse direction, so that the heavy weight of the door 30 opens the underfloor storage chamber D. The rotational force for closing the gear is transmitted from the gear 31a to the outer ring gear portion 37 of the control gear body 35 and acts on the bidirectional locking clutch mechanism 38. However, since the bidirectional locking clutch mechanism 38 is in the locked state, the reverse return direction. The rotational force of is blocked. As a result, the heavy door 30 does not close the opening of the underfloor storage chamber D by its own weight, and the door 30 does not easily close even when an open state is maintained and an unexpected external force such as vibration is applied. Therefore, the articles and the like in the underfloor storage room D can be put in and out with peace of mind. Furthermore, from this state, if a torque greater than a predetermined value is applied to the door 30 in the closing direction, the door 30
The rotational force acts from the gear 31a of the main shaft 31 to the outer ring gear portion 37 of the control gear body 35 meshing with the gear 31a, and the bidirectional locking clutch mechanism 38 incorporated between the main shaft 31 and the support shaft 36 is brought into a free state. . As a result, the door 30 can freely rotate in the closing direction, so that the door 30 can be installed in the underfloor storage chamber D.
Completely close the opening of the. Then, after closing, the bidirectional locking clutch mechanism 38, even if an unexpected external force such as vibration is applied in the opening direction due to the action of the stopping force by applying a slight torque in the opening direction, contrary to the above. The opening 30 does not easily open. Needless to say, when the door 30 is opened against the stopping force, it can be operated again in the opening direction by applying a torque to release the stopping force.

The present invention is not limited to the above-mentioned embodiment, and the control device can be attached to various rotary members such as the rotary shaft portion of the upper part of the swing door.

As described above in detail for the embodiments,
In this invention, the rotating function of the rotating member and the function of controlling the rotating operation of the rotating member are separated, and the rotating member and the control gear body incorporating the bidirectional locking clutch mechanism are shared. Therefore, the main axis of the hardened rotating member can directly support the total weight of the moving body, so even a heavy moving body can be firmly supported and has excellent durability without buckling or damage. It can be moved lightly. At the same time, since the bidirectional locking clutch mechanism is incorporated in the control gear meshed with this rotating member, no load is applied to the bidirectional locking clutch mechanism and the movable body is moved at the final position. It can be stopped reliably and can be held in a locked state at any position during its movement. Even if an unexpected external force is applied, the movable body does not easily move in the other direction, (EN) It is possible to provide a control device for a rotating member, which can exert an excellent effect such as durability due to wear because a bi-directional locking clutch mechanism having a large capacity can be mounted in addition to being able to reliably control the operation. it can.
