[Industrial applications]

 This invention temporarily stops the traveling of a moving body such as a heavy sliding door installed in a hospital, office, library, housing for the elderly, warehouse, etc., or a carrier to move in the opposite direction within a predetermined torque. The present invention relates to a traveling control device capable of being blocked.

[0002]

[Prior art]

Conventionally, sliding doors used for entrances and exits in hospitals, offices, libraries, housing for the elderly, warehouses, etc. It is a structure that can operate. However, for example, due to the rail being slightly inclined, the door roller may naturally rotate in the closing direction or the opening direction during the opening / closing operation of the sliding door. To solve this, the present applicant has previously Hei 4-1769 8 temporarily stops sliding door reverse predetermined torque movement at any position in the middle of the opening and closing as disclosed in 3 JP By developing a sliding door that incorporates a bidirectional locking clutch mechanism that can be stopped within the door roller, we were able to achieve the desired effect.

[0003]

[Problems to be solved by the device]

 However, in this prior art, since the bidirectional locking clutch mechanism is incorporated in the door carriage traveling on the rail, it has to be incorporated in a limited door carriage, and particularly in a heavy sliding door. If it is inserted, the bearing part may not be durable and may buckle. Moreover, when a person goes in and out, it is enough to open the sliding door slightly, but even then the sliding door stops at the open position, so there is the trouble of having to perform the closing operation each time. On the other hand, when a wheelchair or luggage carrier goes in and out, it is more convenient to open the sliding door wide and stop it. Therefore, the present invention has been made in order to solve the problems of the above-mentioned conventional technology and the prior art, and is to form a control section in the traveling path of a moving body such as a heavy sliding door or door. This provides a robust and durable travel control device for a moving body that temporarily and reliably stops the moving body at any position within that section, and blocks movement in the opposite direction within a predetermined torque. The purpose is to do.

[0004]

[Means for Solving the Problems]

 As a means for solving this, the present invention causes a door wheel or a traveling wheel attached to a moving body to travel on a traveling path and urges the moving body to a state in which it is pulled back to one end side, so that the moving body and the traveling path are separated from each other. A rack gear and a pinion gear are attached to one side and a pinion gear to the other side separately from the door wheels or traveling wheels, and a control section is formed by the meshing of both gears.A two-way locking clutch mechanism is directly incorporated in the pinion gear to provide the above control section. The movable body can be temporarily stopped at an arbitrary position inside and is movable in the forward direction, but the movement in the reverse direction can be prevented within a predetermined torque.

Is assembled.

With such a configuration, when the sliding door 5 is moved from the closed state to the opening direction, the door roller 8 attached to the sliding door 5 rotates on the rail 3 and the sliding door 5 freely travels in the free section S. Therefore, when a normal adult goes in and out, since the rail 3 of the open sliding door 5 is slightly inclined toward the closing direction, the sliding door 5 automatically runs in the closing direction to close the sliding door 5. It is possible to close the doorway 1 without performing the above. In the case of carrying in a wheelchair, luggage, etc., when the sliding door 5 is moved in the opening direction so as to open widely, the door roller 8 attached to this rotates on the rail 3 and is fixed to one of the mounting brackets 7. The gear portion 11 of the pinion gear 9 meshes with the rack gear 4 mounted on the lower surface side of the rail 3 and rotates in the control section L. As a result, the pinion gear 9 rotates counterclockwise as shown in FIG. 3, and the bidirectional locking clutch mechanism 12 incorporated therein is operated. In accordance with this, as shown in FIG. 4, the control plate 14 in the inner cylindrical body 13 is rotated in the counterclockwise direction, so that the roller pin located in the locked state at the central shallowest portion 14c of the concave groove 14b formed therein. As shown in FIG. 5, 17 moves to the retreat groove portion 14d on the right side, but at that time, the elastic wire 18 bends in the clockwise direction against the elasticity by the rotation of the pinion gear 9. This is because the center portion of the elastic wire rod 18 is inserted and held in the wire rod fitting groove 15c of the rotation holding body 15, while the inner cylinder body 13 and the holding plate 19 that hold both ends are pinion gears. When the roller pin 17 is rotated in the counterclockwise direction, the roller pin 17 is bent in an arcuate shape against its elasticity. As long as the pinion gear 9 continues to rotate in the counterclockwise direction, it moves to the evacuation groove portion 14d on the right side and maintains the free state. As a result, the bidirectional locking clutch 12 is unlocked with respect to the support shaft 10 and can freely rotate around the support shaft 10 together with the gear portion 11, so that the sliding door 5 can be easily opened in the opening direction. You can move. When the sliding door 5 is completely opened or the opening operation is stopped halfway, the rail 3 is inclined in the closing direction, so that the sliding door 5 is given a predetermined torque in the closing direction, and the door roller 8 is Contrary to the above, it tries to rotate in the counterclockwise direction, but with this a clockwise rotational force acts on the pinion gear 9 meshing with the rack gear 4, and the bidirectional locking clutch mechanism incorporated in the gear portion 11 is engaged. 12, the control plate 14 in the inner cylindrical body 13 rotates in the clockwise direction in accordance therewith, so that 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 that is moving tends to move in the direction of the shallowest portion 14c in the center of the concave groove 14b, and at the same time, the elastic restoring force of the elastic wire 18 curved in a bow shape causes the rotation holding body 15 to rotate counterclockwise. It also acts on the central shallowest part 14 Is pushed back stop pinion gear 9 becomes engaged state as shown in FIG. 5, this stop the rotation of the door rollers 8 meshing. As a result, the sliding door 5 does not return in the closing direction and is opened at the fully open position or an arbitrary stop position, and the sliding door 5 is easily closed even if an unexpected external force such as vibration is applied. Since it does not happen, it is possible to safely access the wheelchair and luggage. Further, if a wheelchair, luggage, etc. pass through the doorway 1 from this state, if a torque greater than a predetermined value is applied to the sliding door 5 in the closing direction, the pinion gear 9 meshed with the rack gear 4 rotates clockwise. As a result, the bidirectional locking clutch mechanism 12 is actuated, and accordingly the control plate 14 in the inner cylindrical body 13 rotates clockwise, so that the central shallowest portion 14c of the concave groove 14b of the control plate 14 as shown in FIG. The roller pin 17, which is pushed back to and is in the locked state, moves to the withdrawal groove portion 14d on the left side and keeps the free state. As a result, the bidirectional locking clutch 12 is unlocked with respect to the support shaft 10, and can freely rotate around the support shaft 10 together with the gear portion 11, so that the sliding door 5 moves in the closing direction lightly. As the vehicle travels, the pinion gear 9 disengages from the rack gear 4 and enters the free section S from the control section L, so the sliding door 5 travels in the closing direction due to the inclination of the rail 3, so the operation of closing the sliding door 5 to the end must be performed. The doorway 1 can be surely closed automatically without the need to perform it.

FIG. 7 and FIG. 8 show a second embodiment mounted on a truck for carrying luggage. The luggage transporting trolley 30 of a heavy moving body has traveling wheels 31 rotatably and pivotally mounted on the four corners of the lower surface thereof, and a rack gear 32 forming a control section L is attached to the center thereof. On the other hand, a rail groove 34 is provided on the floor surface 33 side to form a slightly inclined traveling path on which the traveling wheels 31 can rotate, and a pinion gear 35 is provided between the traveling paths. Are arranged. A bidirectional locking clutch mechanism 38 is incorporated in the pinion gear 35 between a support shaft 36 and a gear portion 37 to rotatably control the gear portion 37, and the support shaft 36 is erected on the floor surface 33. The gear portion 37 is fixed to the mounting bracket 39, and the gear portion 37 is disengageably engaged with the rack gear 32 attached to the carriage 30. The bidirectional locking clutch mechanism 38 is similar to that of the first embodiment.

With such a configuration, the luggage carrier 30 travels along the rail groove 34 by the traveling wheels 31, but when the carrier 30 reaches the pinion gear 35, the luggage carrier 30 is attached thereto. When the carriage 30 is engaged with the rack gear 32 that is engaged and the traveling of the carriage 30 is temporarily stopped during the engaged control section L, the bidirectional locking clutch mechanism 38 incorporated in the pinion gear 35 is used in the first embodiment. It operates in the same manner as the above and becomes locked and is locked when it receives a rotational force in the reverse direction. Therefore, for example, when the traveling road is formed on an inclined surface, the carriage 30 is held in a stopped state without going backward. Even if an inadvertent external force such as vibration is applied, it will not move delusionally. However, since the carriage 30 can continue to move in the traveling direction, the carriage 30 can safely travel on the inclined surface of the traveling path. Further, in this state, when a torque greater than a predetermined value is applied to the carriage 30 in the reverse direction, the bidirectional locking clutch mechanism 38 becomes free in the reverse direction, so that the carriage 30 can be freely reversed.

The control section by the rack gear in the first embodiment may be provided in the entire traveling section. Further, the pinion gears in the second embodiment are not limited to one location, but may be provided at a plurality of locations on the traveling path or the entire traveling section may be used as the control section.

[Effect of the invention]

 As described above in detail with respect to the embodiments, the present invention allows the door roller or the traveling wheels mounted on the moving body to travel along the running path, and urges the moving body to return to the one end side. A rack gear and a pinion gear that meshes with the rack gear are attached to the traveling path separately from the door wheels or traveling wheels to form a control section, and the gear has a function to control traveling of the moving body in both directions. Since the locking clutch mechanism is incorporated, the weight of the moving body is not directly applied to the bidirectional locking clutch mechanism, and the bidirectional locking clutch mechanism operates smoothly when moving the moving body. In areas other than the control section, in a free state, the moving body can be pulled back to the one end side to move along the traveling path, and can automatically return to the initial moving state. In addition, in the control section, the moving body is temporarily stopped at an arbitrary position, and the moving body is urged to be pulled back to one end side, so that the moving body is surely prevented from moving in the opposite direction indefinitely. It is possible to prevent the occurrence of an injury or an accident by the mobile body going backwards carelessly. (EN) Provided is a traveling control device for a moving body, which exerts an excellent effect such that the lock of the bidirectional locking clutch mechanism is released when a torque more than a predetermined value is applied and the moving body can be moved freely. Is something that can be done.
