Description

Opening and closing device with lock

Technical sector

The present invention relates to an opening and closing apparatus with locking, which allows opening and closing movements and locking in a completely closed position of sliding doors of sliding separation type, mounted in a housing in a way with movement reciprocal.

State of the art

As a conventional example of an opening and closing apparatus with locking, which allows opening and closing movements and locking in a completely closed position of sliding doors, mounted in a housing in a manner with reciprocating movement, is an opening and closing apparatus. sliding door closure described as a second embodiment in patent document 1 (Japanese patent application published without examining No. 2000-142392). With the provision of patent document 1, two sliding doors are arranged as opening and closing doors of the sliding separation type that are coupled by a rack and pinion mechanism, and rail movement elements that suspend the sliding doors and a A linear motor frame for opening / closing of sliding doors is coupled by means of a damping element damping element that includes a damping spring. The sliding doors move in closing directions by driving the linear motor frame, and even when the sliding doors reach a completely closed position, the frame is further operated to stretch the spring of the damping element. Then, a metal pressure element, arranged at a front end of the frame, moves a sliding cam device to slide against a return spring, and since a cam follower that descends in accompaniment also causes a retention lock to descend , the retention lock is retained in a hole provided in a rack and pinion mechanism rack, thereby locking the sliding doors in the fully closed position.

With this arrangement, although a linear motor drive force is normally assigned to drive the opening and closing of the sliding doors by means of the damping spring of the damping element, when the sliding doors reach the fully closed position, the driving force of the linear motor is assigned to the sliding cam device and the blocking is carried out by means of the retention lock. Therefore, the driving force of a single linear motor (actuator) is used both for the opening / closing drive and for the blocking operation, providing the advantage that the arrangement can be simplified.

Object of the invention

In the provision of patent document 1, zippers are arranged above and below a pinion gear and the pair of left and right sliding doors are respectively coupled to the zippers to open and close the sliding doors of the sliding separation type, and By limiting a rack on one side, the sliding door on the other side is limited by the pinion gear. Therefore there is a problem that when the pinion gear or a rack is broken, the lock of the other door is disengaged. Although the pinion and rack gear can be manufactured robustly, this leads to increased installation space, increased cost and other problems.

In the arrangement of patent document 1, the damping element, which is a mechanism that switchably allocates the driving force of the linear motor to the opening / closing drive of the sliding doors and to the pressure movement of the sliding cam device , is arranged to move slidably along with the sliding doors. Therefore, the overall arrangement is complex, it is necessary to guarantee a space for the movement of the damping element, and a simple and compact arrangement cannot be made for the sliding door opening and closing locking device.

Also because the sliding cam device is moved by pressure to stretch the damping spring of the damping element in the fully closed position of the sliding doors, when, for example, a load is applied (a resistance against the closing of the sliding doors) by wind pressure, etc., to the doors immediately before reaching the fully closed position, the damping spring is stretched before the sliding doors reach the fully closed position. Consequently, the metal pressure element at the front end of the frame moves the sliding cam device by pressure at a stage that is too early, causing the retention lock to descend without the positions of the retention lock and the hole in the zipper correspond, and can therefore cause a breakage of the retention lock or the hole or limit the sliding doors before reaching the fully closed position (in the open state).

In addition, when, in the closed, locked state, of the sliding doors, the linear motor loses its driving force due to a malfunction of the linear motor, power supply failure due to a power outage, or other circumstance, Since the frame and the metal pressure element are then pulled in the direction of releasing the pressure of the sliding cam device and the sliding cam device is also forced back by the return spring, the retention lock is raised together With the cam follower and the lock is released. This means that a closed lock is unintentionally released with a malfunction or failure of the power supply. In a case where the sliding doors are used as side doors of a rail vehicle, this means that the doors open before the vehicle stops and is therefore also unfavorable in terms of safety.

In a case where the damping spring is made strong to prevent the retention lock from falling too early even when some load acts on the sliding doors, given that the force, acting in the direction of release of the lock when the driving force of the linear motor is lost due to a failure of the power supply, etc., it also becomes strong, the probability of unintentional unlocking also increases. That is, the two issues described above are in a relationship of mutual conflict and there is still a need to propose a provision that resolves both issues simultaneously at a satisfactory level.

The present invention has been carried out in view of the above circumstances, and an object thereof is to provide an opening and closing apparatus with locking with a simple and compact arrangement that allows to securely lock sliding doors of the sliding separation type. and allow the opening / closing and closing of the sliding doors with a single actuator.

The present invention relates to an opening and closing apparatus with locking, which allows opening and closing and locking movements to be carried out in a completely closed position of sliding doors of sliding separation type, mounted in a housing in a manner with reciprocal movement . To achieve the above object, an opening and closing apparatus with lock according to the present invention has the aspects described below. That is to say, the opening and closing apparatus with lock according to the present invention has any of the following aspects individually or combined in a suitable manner.

To achieve the above object, a first aspect of an opening and closing apparatus with locking according to the present invention is that the opening and closing apparatus with locking includes: a rack and pinion mechanism, which has a pair of zippers, mounted respectively in a pair of sliding doors of sliding separation type that can move reciprocally with respect to a housing, and a pinion engaged with the pair of zippers; an actuator, which functions as a source of opening / closing of the sliding doors; a locking mechanism mounted in the housing and which allows the pair of sliding doors to be locked in a completely closed position by limiting the respective movements of locking elements that are respectively fixed to the respective sliding doors of the pair of sliding doors; a switching mechanism for switching the locking mechanism between a locked state and an unlocked state; and a planetary gear mechanism, which has an input part, into which a driving force of the actuator is introduced, a first output part, which allows the driving force to be emitted to the pinion, and a second output part, which allows the actuation force to be emitted to the switching mechanism; and when the sliding doors are in the fully closed position, the driving force is emitted from the second output part towards the switching mechanism.

With the above arrangement, since the movements of the blocking elements, which are respectively fixed to the respective sliding doors of the pair of sliding doors, are respectively limited by the locking mechanism, each of the pair of sliding doors can be independently locked. Therefore, even when the rack and pinion mechanism malfunctions, the state in which the movements of both sliding doors are locked can be maintained. On the contrary, when the rack and pinion mechanism operates normally, although the blocking of one of the sliding doors is released due to malfunction, etc., since the sliding door is coupled to the other sliding door by means of the rack mechanism and pinion, as long as the blocking of the other sliding door is effective, the sliding door can be kept in the locked state. Therefore, sliding doors of the sliding separation type can be locked more securely.

Also with this arrangement, the power of the actuator is assigned by the planetary gear mechanism to drive the pinion of the rack and pinion mechanism on one side and to operate the switching mechanism on the other side. Since the arrangement for the transmission (allocation) of power from the actuator is thus housed in a compact space, the structure can be simplified and an opening and closing apparatus with compact locking can be provided.

In addition, since the driving force from the actuator is assigned using not a damping spring as in patent document 1 but a planetary gear mechanism, although the driving force is lost due to the malfunction of the actuator, etc., in the state in which the doors

sliders are locked in the closed position, a force is not applied in a direction of release of the lock to the switching mechanism, etc., and unintentional unlocking is prevented.

A second aspect of the opening and closing apparatus with locking according to the present invention is that the switching mechanism has a switching element that allows switching the locking mechanism between the locked state and the unlocked state moving according to the actuation of the second part of exit, and the locking mechanism is arranged so that the movement of the switching element is prevented when the sliding doors are in positions other than the fully closed position and the movement of the switching element is allowed when the sliding doors are in the position completely closed.

With this arrangement, since the movement of the switching element is prevented when the sliding doors are in positions other than the completely closed position, the blocking operation is performed when the sliding doors have reached the completely closed position safely. That is to say, the blocking operation is prevented at a time that is too early in the operation of the sliding doors in closing directions, and thus the breakage of the locking mechanism and the limitation of the sliding doors are prevented. before reaching the fully closed position.

A third aspect of the opening and closing apparatus with locking according to the present invention is that the locking mechanism includes a link mechanism, deformable to a rectilinear state and to a flexed state according to the movement of the switching element, and a retention mechanism of link, which retains the link mechanism in the flexed state when the sliding doors are in positions other than the fully closed position, and when the sliding doors are in the fully closed position, the link mechanism deforms to the rectilinear state and from that mode limits the movement of the locking elements fixed to the sliding doors.

With this arrangement, the movements of the sliding doors can be locked in the completely closed position by placing the link mechanism in the rectilinear state, and since in positions other than the completely closed position the link mechanism is maintained in the flexed state by means of the link retention mechanism, the blocking operation is performed after the sliding doors have reached the fully closed position. Therefore, the locking mechanism can be formed in a compact manner because it is operated using the linking mechanism and a stable drive can be performed because the locking mechanism is mechanically actuated.

A fourth aspect of the opening and closing apparatus with locking according to the present invention is that each blocking element is constituted by a locking bolt, fixed to the sliding door to extend in a vertical direction, the link retention mechanism is constituted by a couple of engaging elements, rotatably installed near both ends of the linkage mechanism and each having a first engaging part, which engages with the locking bolt in the fully closed position, and a second engaging part, which engages with one end of the linkage mechanism in the rectilinear state in the fully closed position, and the engagement elements impede the movement of the switching element preventing the transition of the linkage mechanism to the rectilinear state when the sliding doors are in different positions of the fully closed position, and allow the movement of the switching element when driven by the locking bolts to rotate to positions that allow the coupling of the ends of the link mechanism with the second engagement parts during the movement of the sliding doors in the closing directions.

With this arrangement, in the fully closed position, the hooking elements engage with the locking bolts. Then, by extending the link mechanism to the rectilinear state, the engagement elements engage with the ends of the link mechanism and are limited in terms of rotational movement. The locking bolts are thus limited in terms of movement in the state of being engaged with the engagement elements. Therefore, by means of the engagement elements, the transition of the link mechanism to the rectilinear state in positions other than the completely closed position can be prevented and the movement of the locking bolts in the completely closed position can be limited. Therefore, the number of parts necessary to form the locking mechanism can be made small and a more compact locking mechanism can be arranged.

A fifth aspect of the opening and closing apparatus with locking according to the present invention is that the switching element is constituted by a sliding sliding element that allows sliding movement in a direction with respect to the locking mechanism and having a part of grooved in a curved manner as in a lower surface, the link mechanism operates within a plane parallel to the lower surface of the sliding slide element and has a coupling bolt, arranged at a coupling point, inserted in the groove part, and the link mechanism is deformed to the rectilinear state and to the flexed state by means of the coupling bolt that moves along the groove part.

With this arrangement, the linkage mechanism can be deformed to the rectilinear state and to the flexed state by moving the blocking sliding element in one direction without interposing another element between the

Sliding lock element and link mechanism. Therefore, the installation space of the locking mechanism can be made small.

A sixth aspect of the opening and closing apparatus with locking according to the present invention is that the linking mechanism can deform to the rectilinear state and to the flexed state within a horizontal plane.

With this arrangement, when the sliding doors reach the fully closed position, the sliding doors can be locked by operating the switching mechanism and deforming the link mechanism to the rectilinear state within the horizontal plane. Since the locking mechanism therefore places the sliding doors in the locked state using the linking mechanism that operates within the horizontal plane, the installation space of the locking mechanism can be made small in the height direction.

A seventh aspect of the lock opening and closing apparatus according to the present invention is that the link mechanism has a link part, rotatably fixed to the housing, and a movement of one end of the link mechanism is limited by a notch of rectilinear guide provided in the accommodation.

With this arrangement, by rotatingly fixing the link part which is a part of the link mechanism to the housing, the position of the link mechanism with respect to the housing can be fixed without obstructing the operation of the link mechanism. The movement of the end of the link mechanism can be limited to a straight line by the guide notch of the housing, and therefore a link mechanism that can be deformed to the rectilinear state and to the bent state can be deformed by a simple arrangement.

An eighth aspect of the opening and closing apparatus with locking according to the present invention is that each locking element is constituted by a locking bolt, fixed to the sliding door so that it extends in a vertical direction, and the locking mechanism includes furthermore a coupling element, rotatably installed within a horizontal plane near one end of the linkage mechanism and having a first coupling part, which engages with a locking bolt in the fully closed position, and a second part of engagement, which engages with the end of the link mechanism in the rectilinear state in the fully closed position.

With this arrangement, by extending the locking bolt in the vertical direction from the sliding door, the locking mechanism operating within the horizontal plane can be easily engaged with the locking bolt. Since in the fully closed position, the movement of the locking bolt can be limited by limiting the rotation of the engagement element by the end of the link mechanism in the rectilinear state, the direction in which the link mechanism extends to the rectilinear state can set to any direction that allows the limitation of the rotation of the coupling element. Therefore, for example, a design can easily be made to prevent a force, which deforms the link mechanism from the rectilinear state into the bent state in the locked state, from the engagement element, and the locked state can be maintained from most reliable way.

A ninth aspect of the opening and closing apparatus with locking according to the present invention is that the switching mechanism has a switching element, which can be moved within a horizontal plane according to the drive of the second output part, and the link mechanism. it can be deformed to the rectilinear state and to the flexed state by the movement of a coupling bolt, arranged at a coupling point of the link mechanism, according to the movement of the switching element.

With this arrangement, since the switching element can move within a horizontal plane, the installation space can be made small in the height direction. In addition, the switching element can switch the state of the link mechanism by using the coupling bolt that constitutes the link mechanism, and therefore a simple arrangement can be made with a small number of parts.

A tenth aspect of the opening and closing apparatus with locking according to the present invention is that the switching element is a sliding sliding element that allows sliding movement in a direction within a horizontal plane according to the actuation of the second output part and having a groove portion curved in a lower surface, a coupling bolt, disposed at a coupling point of the linkage mechanism, is inserted into the slot portion, and the linkage mechanism may deform to the rectilinear state and to the flexed state by means of the coupling bolt, arranged at the coupling point of the linkage mechanism, which moves along the groove part according to the movement of the sliding sliding element.

With this arrangement, the movement of the link mechanism can be limited by using the groove portion on the lower surface of the sliding slide element that allows sliding movement within the horizontal plane. Since the groove part has a curved shape, an arrangement that guides the coupling bolt in a direction that differs from the direction of movement of the sliding slide element can be made more easily.

A thirteenth aspect of the opening and closing apparatus with locking according to the present invention is that the opening and closing apparatus with locking further includes: an elastic element; and a collision detection unit, arranged in the housing and which stops actuator actuation when a deformation amount of the elastic element reaches a predetermined deformation amount during a closing operation of the sliding doors; and the second output part is allowed to emit the actuator driving force to the elastic element.

With this arrangement, if during the operation of closing the sliding doors (during the movement of the sliding doors from a fully open position to the fully closed position), a sliding resistance of the sliding doors is less than a predetermined sliding resistance, Since the rotation of the second output part is suppressed by an elastic force of the elastic element, the actuator driving force is transmitted from the first output unit to the pinion and the operation of closing the sliding doors is performed. During the closing operation of the sliding door, a passenger gets caught or a sliding door collides with a passenger, a force not less than the normal sliding resistance is applied to a sliding door, and if the predetermined sliding resistance is exceeded , the second outlet part rotates against the elastic force of the elastic element and the elastic element undergoes elastic deformation. When this amount of elastic deformation reaches a predetermined amount, actuator actuation is stopped by the collision detection unit. Since the collision detection unit is arranged in the housing just like the actuator, the door hitch and the collision during the closing operation of the sliding door can be detected without complicating the wiring. With this arrangement, collision detection is allowed regardless of whether the sliding doors are accelerating or decelerating and collision detection can be performed throughout the entire range of movement of the sliding doors.

A twelfth aspect of the opening and closing apparatus with locking according to the present invention is that the elastic element is disposed between the second outlet part and the switching element.

With this arrangement, the output of the second output part can be used to drive the switching element to switch the locking mechanism and cause a force to act on the elastic element at the same time. Therefore, for example, while in a case where the elastic element is installed in another position, the driving force of the second output part in the switching of the locking mechanism is assigned between the elastic element, installed in the another position, and the switching element, when the elastic element is installed between the second output part and the switching element, the force applied to the elastic element is also actuated on the switching element, thereby allowing detection Collision and blocking operation are performed efficiently.

A thirteenth aspect of the opening and closing apparatus with locking according to the present invention is that the collision detection unit is constituted by a limit switch that stops actuator actuation after detecting that a rotation angle of the second output part is has returned not less than a predetermined angle of rotation.

With this arrangement, the limit switch detects the angle of rotation of the second output part, which rotates in correspondence with the deformation of the elastic element, to stop actuator actuation. Therefore, the collision detection unit can be arranged with a simple arrangement.

A fourteenth aspect of the opening and closing apparatus with locking according to the present invention is that the elastic element is arranged to balance with a sliding resistance when the sliding doors are performing a normal closing operation.

With this arrangement, "performing a normal closing operation" refers to a state in which a force that obstructs the operation of the sliding doors is not acting from the outside, and since an elastic force is made that is balanced with The displacement resistance during this normal closing operation acts on the second outlet part by means of the elastic element, the elastic force that is caused to act by the elastic element is made to be smaller. Therefore, the elastic element can be installed in an easily deformable state. Since this makes the elastic element more easily deformable by increasing the sliding resistance of the sliding doors, a higher sensitivity detection is allowed. Also in this case, an impact applied from a sliding door to a collision object can be significantly relaxed in a collision process.

Detailed description of the invention

A better way of carrying out the present invention will now be described with reference to the drawings. Figure 1 is a front view of an embodiment, in which an opening and closing apparatus with lock is installed in an opening / closing door of a vehicle. Figure 2 is a front view of main parts of an arrangement of the opening and closing apparatus with lock in an unlocked state. Figure 3 is a schematic view of an arrangement of a locking mechanism, shown in Figure 2, seen from a bottom side of the locking mechanism (from a direction indicated by an arrow (X) in Figure 2). Figure 4 is a front view of main parts of the arrangement of the opening and closing apparatus with locking in a locked state. Figure 5 is a schematic view of the locking mechanism, shown in Figure 4, seen from the bottom side of the locking mechanism (from a direction indicated by an arrow (X) in Figure 4). Figure 6 is a schematic partial sectional view of the locking mechanism and a sliding sliding element seen in a direction of movement of the blocking sliding element (from a direction indicated by an arrow (Y) in Figure 4). In Figure 6, a planetary gear mechanism is located on one side (C1), and the sliding doors are located on one side (C2).

The vehicle opening and closing door (1), shown in Figure 1, is arranged as a door that allows opening and closing an opening formed in a side wall of a railway vehicle or other vehicle and has a pair of doors ( 11A and 11B) left and right sliders of slip separation type. The two sliding doors (11A and 11B) are arranged in a way that allows reciprocal movement along a rail

(2) guide installed horizontally above the opening. More specifically, suspension elements (3A and 3B) are fixed to respective upper edges of the sliding doors (11A and 11B), and door rollers (4) are axially rotatably supported on each of the elements (3A and 3B ) of suspension. Each door roller (4) can roll along the guide rail (2).

The vehicle opening and closing door (1) is arranged to open and close and to automatically lock so that it does not open unintentionally in a closed state by means of the lock-open and close apparatus according to the embodiment of the present invention. It is dangerous for a door of a rail vehicle or other vehicle to open while the vehicle is in motion and a door of this type is required to lock securely so that it does not open unintentionally during travel.

Details will now be described. A plate-like base (5) is fixed to an upper part (upper side of the opening) of the side wall (housing) of the vehicle, and two zippers (7A and 7B) are supported on a support

(6) Zip fastened to the base (5). The zippers (7A and 7B) are arranged being longitudinal directions thereof horizontally aligned (parallel to the guide rail (2)), and are supported by sliding supports (8) in a manner that allows sliding in the longitudinal directions ( horizontal directions).

The two zippers (7A and 7B) are arranged in parallel with each other forming an appropriate interval in an up / down direction and are arranged so that teeth thereof are facing each other. A pinion (9) is rotatably arranged to simultaneously engage the teeth of both of the two zippers (7A and 7B). The pinion (9) is arranged in a position that is a central position in a left / right direction above the opening of the opening and closing door (1) and is a position that is sandwiched above and below by the two zippers (7A and 7B).

Arm elements (13A and 13B) are installed respectively at the ends of the two zippers (7A and 7B). The arm elements (13A and 13B) are respectively fixed to the suspension elements (3A and 3B) by coupling elements (15a and 15b). The ends of the zippers (7A and 7B) are respectively coupled to the corresponding sliding doors (11A and 11B) by means of the arm elements (13A and 13B). A rack and pinion mechanism (10) consists of the zippers (7A and 7B) and the pinion (9), and the two sliding doors (11A and 11B) are operated to open and close by means of the rack mechanism (10) and pinion. By coupling the left and right sliding doors (11A and 11B) together, the rack and pinion mechanism (10) also serves a function of performing the symmetrical opening and closing of the sliding doors (11A and 11B).

As shown in Figures 2 and 4, the locking bolts (14A and 14B) (locking elements), which extend vertically upwards, are respectively fixed to the pair of arm elements (13A and 13B). The movement of the pair of sliding doors (11A and 11B) is blocked by limiting the locking bolts (14A and 14B) by means of a locking mechanism (60) to be described later.

The planetary gear mechanism (20) is supported on the base (5) (see Figures 2 and 4). The mechanism

(twenty)

 The planetary gear has a central gear (21), axially supported in a rotating manner, planetary gears (24), arranged in plurality on an outer circumference of the central gear (21) and which are allowed to undergo rotation and revolution while engaged with the central gear (21), an internal gear (22) (first exit part), which has internal teeth that engage with the planetary gears (24) on an outer side of the planetary gears (24) , and a carrier (23) (second output part), which rotatably supports the planetary gears (24). The three components of the gear

(twenty-one)

 central, the internal gear (22) and the carrier (23) are located along the same axial line and are arranged to rotate respectively with respect to each other. The axial line of these three components also corresponds to an axial line of the pinion of the rack and pinion mechanism (10).

An output shaft of an electric motor of direct drive type (actuator), omitted from the illustration and which is allowed to rotate in a direct and reverse direction, is coupled to the central gear (21). The coupling can be achieved by a suitable speed reducing mechanism. A main unit part of the electric motor is fixed to the side wall of the vehicle. The internal gear (22) is coupled to the pinion (9) of the rack and pinion mechanism (10) by means of a bolt not shown, etc. In addition, the carrier (23) is coupled to a traction element (70) for pulling a blocking slide element (33) to switch the blocking mechanism (60) described below between a locked state and An unlocked state.

The traction element (70) and the sliding slide element (33) are installed in a manner that allows reciprocal movement in one direction along a guide shaft (72), fixed with respect to the base (5) and extending parallel to the zippers (7A and 7B), and constitute a switching mechanism for switching the locking mechanism. The traction element (70) is coupled to the carrier (23) to be able to move in the direction according to the rotation of the carrier (23). A spring (71) torsional torque limiter (elastic element) in the form of a helical spring is disposed between the traction element (70) and the sliding sliding element (33). The torque-limiting spring (71) causes an elastic force to act on the traction element (70) and the sliding sliding element (33) to push the traction element (70) against the sliding element (33) of blocking. That is, the torque limiting spring (71) is arranged to suppress the relative movement of the traction element (70) with respect to the blocking sliding element (33).

The sliding sliding element (33) has, at its upper end, a mounting part (33a) and a mounting part (33b) that are separated by a predetermined interval in the direction of movement and are formed to be able to slide with respect to to the guide tree (72). The sliding slide element (33) also has a front surface part (33c), which extends downwardly from the mounting part (33a) and the mounting part (33b), and a lower surface part (33d) , formed to flex 90 degrees in a direction directed inwards from the surface of the paper in Figure 2 from a lower end of the front surface part (33c) (see Figures 3, 5 and 6). the traction element (70) is mounted on the guide shaft (72) between the mounting part (33a) and the mounting part (33b), and the torsion torque limiting spring (71) is mounted on the shaft (72) of a guide between the traction element (70) and the mounting part (33b) on a front end side in a blocking direction (direction indicated by an arrow (A1) in Figures 3 and 5; referred to as hereinafter "address (A1) of blocking") of the element (33) sliding lock. Since the torque-limiting spring (71) is mounted in a state of being compressed in an axial direction (an elastically deformed state), the tensile element (70) receives an impulse force directed towards the part (33a) assembly and a

end of the traction element (70) is thereby retained in a state of contact with the mounting part (33a).

As shown in Figures 3 and 5, the sliding slide element (33) has, in the lower surface part (33d), a groove (33e) (groove part) of curved shape. The slot (33e) includes a first part

(A) of hole, which extends parallel to the direction of movement, and a second part (B) of hole, formed to be continuous with the first part (A) of hole and gently bend in a direction substantially perpendicular to the direction of movement

The mechanism (60) for locking the opening / closing door (1) will now be described in detail. Figure 7 is a schematic partial sectional view of the locking mechanism (60) in the locked state seen from a horizontal direction. In Figure 7, the planetary gear mechanism is located on one side (C1), and the sliding doors are located on one side (C2). The locking mechanism (60) is a mechanism that operates within a horizontal plane and is installed to be adjacent to an upper side (planetary gear mechanism side (20)) of the lower surface portion (33d) of the element ( 33) Sliding lock and to be fixed in position with respect to the base (5) (see Figures 2 and 4).

As shown in Figures 3 and 5, the locking mechanism (60) is constituted by a link mechanism (61) that can deform to a rectilinear state and to a flexed state within a horizontal plane and a mechanism (65) Link retention that works within the horizontal plane. The link mechanism (61) is formed by coupling three links (62a, 62b and 62c). In a central part in its longitudinal direction, the central link (62a) is rotatably fixed with respect to the base (5) by a coupling bolt (63a). One end of the central link (62a) is coupled to one end of the link (62b) by means of a coupling bolt (63b). The other end of the central link (62a) is coupled to one end of the link (62c) by a guide coupling bolt (63c). The links (62b) and the link (62c) have bolts (63d and 63e) at ends on the sides opposite the coupling points with the link (62a).

As shown in Figures 3, 5 and 7, the bolts (63d and 63e), located at the ends of the link mechanism (61), have ends thereof respectively inserted in guide notches (80A and 80B) ( indicated by lines of a long line and two alternate shorts in figures 3 and 5), formed in a rectilinear manner and parallel to the direction of movement of the blocking element (33), and are installed in a manner that allows movement to along the notches (80A and 80B) guide. That is, the movements of the bolts (63d and 63e) are respectively limited by the guide notches (80A and 80B). The ends of the bolts (63d and 63e) that are inserted in the guide notches (80A and 80B) are formed as rollers (see Figure 7), allowing friction to be reduced with respect to the guide notches (80A and 80B) and gently perform the movements of the ends. The ends of the bolts (63d and 63e) on the side of the sliding slide element (33) are also formed as rollers (see Figure 7), allowing friction to be reduced during movements along element edges (66A and 66B ) hitch, which will be described below, and stabilize the blocking operation.

One end on the side of the sliding locking element (33) of the guide coupling bolt (63c) of the connecting mechanism (61) is formed as a roller and is inserted into the groove (33e) of the sliding element (33) of blocking. Therefore, the position of the guide coupling bolt (63c) is limited by the position of the locking slide element (33). Therefore, the linkage mechanism (61) can be switched between the rectilinear state and the flexed state by movement of the blocking sliding element (33).

The link retention mechanism (65) is constituted by a pair of coupling elements (66A and 66B), symmetrically installed with respect to the link mechanism (61) (with respect to the coupling bolt (63a)) in positions near the respective ends of the linkage mechanism (61) and in a manner that allows rotations within a horizontal plane, and a coupling spring (69), which couples the pair of engagement elements together. The coupling elements (66A and 66B) respectively have, in peripheral parts thereof, first parts (67A and 67B) of engagement and second parts (68A and 68B) of engagement, and axes (81A and 81B) of rotation of the coupling elements (66A and 66B) are fixedly installed in the base (5) (see figure 7). An expansion element (82) is fixed to the pair of rotating shafts (81A and 81B), and the coupling bolt (63a) to rotatably fix the central link (62a) of the link mechanism (61) is supported by the expansion element (82) (see Figures 2 and 4).

In a state in which an external force is not received by the link retention mechanism (65), the engagement elements (66A and 66B) receive a force from the coupling spring (69) and are retained in a state shown in Figure 3. In this state, the coupling elements (66A and 66B) limit, by their peripheral parts (parts indicated by the arrows (P2) in Figure 3), an extension movement of the link mechanism (61) to the rectilinear state. Therefore, when the link mechanism (61) is maintained in the flexed state by means of the engaging elements (66A and 66B), the movement of the blocking sliding element (33) in the blocking direction (A1) is limited by the slot (33e) and guide coupling bolt (63c).

Meanwhile, the engagement elements (66A and 66B) are formed to rotate, against the impulse force of the coupling spring (69), in directions (directions indicated by the arrows (R1) in Figure 3) that cause the second parts (68A and 68B) of engagement approach the link mechanism (61) when edges (parts indicated by (P1) in Figure 3) of the first parts (67A and 67B) of engagement are driven by the movement of the locking bolts (14A and 14B), respectively fixed with respect to the sliding doors (11A and 11B), in closing directions (directions indicated by the arrows (B1) in Figure 3; hereinafter referred to herein as " closing addresses (B1) ”). In a state in which the sliding doors (11A and 11B) are in a completely closed position, the locking bolts (14A and 14B) and the first engagement parts (67A and 67B) are engaged as shown in the figure 5, and the positions of the second engagement parts (68A and 68B) are positions that allow the engagement with the bolts (63d and 63e) arranged at the ends of the link mechanism (61). That is, the engagement elements (66A and 66B) enter a state of not limiting the deformation of the link mechanism (61). If at this point the blocking slide element (33) moves in the blocking direction (A1), the link mechanism (61) is made to pass from the flexed state to the rectilinear state when the connecting connection bolt (63c) moves. guided along the groove (33e). The bolts (63d and 63e), located at the ends of the linkage mechanism (61) are then engaged with the second engagement parts (68A and 68B) of the engagement elements (66A and 66B). In this way the rotations of the coupling elements (66A and 66B) are limited. Therefore, the movements of the locking bolts (14A and 14B) in opening directions (directions indicated by the arrows (B2) in Figures 3 and 5; hereinafter referred to as "opening directions (B2)") ) are limited by the first parts (67A and 67B) of hitch.

Opening / closing and locking operations of the sliding doors (11A and 11B) will now be described with reference to Figures 2 to 5. Figure 2 shows a way in which the sliding doors (11A and 11B) move in the closing directions (B1) and shows a state in which the locking mechanism (60) is unlocked. In this state, the locking bolts (14A and 14B) are in positions away from the locking mechanism (60) and the locking mechanism (60) is limited in the state shown in Figure 3.

In this unlocked state, the link mechanism (61) is in the flexed state and the rectilinear extension movement of the link mechanism (61) is limited by the engagement elements (66A and 66B). The movement of the blocking slide element (33) in the blocking direction (A1) is therefore limited by the guide coupling bolt (63c) of the link mechanism (61) and the groove (33e).

Therefore, while in the unlocked state of Figures 2 and 3, the central gear (21) of the mechanism

(20) planetary gear is driven by the electric motor, a driving force is transmitted to the pinion (9) by the internal gear (22) or is transmitted to elastically deform the torsion torque limiting spring (71) by the carrier (23) which rotates according to the revolution of the planetary gears (24).

In this case, the torque-limiting spring (71) drives the traction element (70), coupled to the carrier (23), to cause a predetermined elastic force, which suppresses the rotation of the carrier (23) according to the revolution of the planetary gears (24), act on the carrier (23) to balance with a sliding resistance during a normal closing operation of the sliding doors (11A and 11B). Therefore, while in the normal closing operation, the central gear (21) of the planetary gear mechanism (20) is driven by the electric motor, the planetary gears (24) only rotate and have no revolution, and therefore all The driving force of the central gear (21) is transmitted to the pinion (9) by the internal gear (22) and the sliding doors (11A and 11B) are actuated to open / close.

In addition, although the sliding doors (11A and 11B) move in the closing directions (B1), the engagement elements (66A and 66B) of the locking mechanism (60) that engage with the bolts (14A and 14B) of They receive the elastic force of the coupling spring (69), therefore they are retained in the state shown in figure 3, and do not rotate to the locked position (position shown in figure 5) until the doors (11A and 11B) sliders reach the fully closed position. Therefore, the locking mechanism (61) can be prevented from operating too soon before the sliding doors (11A and 11B) reach the fully closed position. Therefore, there is no malfunction of the locking mechanism (60) due to the collision of the locking bolts (14A and 14B) with the engagement elements (66A and 66B) that have been introduced in the locked positions.

When, during the closing operation of the sliding doors (11A and 11B), the sliding resistance of the sliding doors (11A and 11B) becomes significantly large because a passenger is hooked, etc., the carrier (23 ) rotates against the force of impulse due to the torque-limiting spring (71), the rotation of the carrier (23) is detected, and the rotation of the electric motor is temporarily stopped or another predetermined safety operation is performed as a consequence such as It will be described below.

Next, it should be considered that as a result of the operation of the central gear (21) in the closing direction of the sliding doors (11A and 11B), the sliding doors (11A and 11B) approach the fully closed position and the bolts ( 14A and 14B), which are fixed with respect to the sliding doors (11A and 11B), come into contact with the coupling elements (66A and 66B) (see Figure 3). When

drives the central gear (21) from this state to move the sliding doors (11A and 11B) additionally in the closing directions (B1), the locking bolts (14A and 14B) drive the engagement elements (66A and 66B) and they enter recesses of the first parts (67A and 67B) of engagement while the engagement elements (66A and 66B) are rotated in the directions of the arrows (R1) in Figure 3.

When the sliding doors (11A and 11B) reach the fully closed position, the engagement elements (66A and 66B) engage with the locking bolts (14A and 14B) in the first engagement parts (67A and 67B), and are It completes the transition to the locked position, in which the second engagement parts (68A and 68B) are confronted with the bolts (63d and 63e) located at the ends of the link mechanism (61). This allows the transition of the link mechanism (61) to the rectilinear state. Therefore, when the sliding doors (11A and 11B) move to the fully closed position, the sliding sliding element (33) is allowed, which is coupled by the guide coupling bolt (63c) and the groove (33e) to the mechanism

(61) link that is allowed to enter the rectilinear state, move in the blocking direction (A1). Accordingly, rotation of the carrier (23), coupled to the sliding slide element (33) by the torsional torque limiting spring (71) and the traction element (70) is allowed.

Meanwhile, after reaching the fully closed position, the sliding doors (11A and 11B) cannot move in the closing directions (B1). Therefore, rotation of the internal gear (22), coupled to the sliding doors (11A and 11B) by the rack and pinion mechanism (10), is also prevented. Therefore, the driving force of the central gear (21) that continues to rotate is now transmitted to the carrier (23) so that the carrier (23) rotates counterclockwise in Figure 2 and the sliding slide element (33) is moves in the blocking direction (A1) by means of the spring (71) torque limiter and the traction element (70). According to the movement of the blocking slide element (33) in the blocking direction (A1), the link mechanism (61) passes from the flexed state (the state shown in Figure 3) to the rectilinear state (the state shown in the figure 5). In the rectilinear state, the rotations of the engagement elements (66A and 66B) are limited by the bolts (63d and 63e) of the link mechanism (61). Therefore, movements of the locking bolts (14A and 14B) that are engaged with the first parts (67A and 67B) of engagement of the engagement elements (66A and 66B) are prevented. Therefore the movements of the sliding doors (11A and 11B) are blocked by the locking bolts (14A and 14B). A locking spring (73) that drives the mounting part (33a) of the locking element (33) in the blocking direction (A1) is installed in the guide shaft (72), and this prevents the element ( 33) Sliding lock in the locked position returns to the unlocked position and allows to keep the locked state more reliably.

Therefore, as illustrated by the deformation of the state shown in Figures 2 and 3 to the state shown in Figures 4 and 5, the locking mechanism (60) automatically switches to the locked state after moving the doors (11A and 11B ) sliding to the fully closed position, and thereby blocking the sliding doors (11A and 11B) as they are in the closed state. The lock that is coupled with the closing of the sliding doors (11A and 11B) can therefore be performed simply by driving the central gear (21) of the planetary gear mechanism (20) by a single actuator and the drive arrangement can be made to be simple.

In addition, in the locked state shown in Figures 4 and 5, the lock can be applied twice, that is, the lock limiting the rotations of the engagement elements (66A and 66B) by the mechanism (61) can be applied. linkage and blocking that limits the deformation of the link mechanism (61) from the rectilinear state to the flexed state by the sliding element (33). Therefore, for example, even when a state is entered in which no electric power is supplied to the electric motor due to a power outage or malfunction, etc., of a vehicle and the rotation of the output shaft is released ( the central gear (21)), the opening of the sliding doors (11A and 11B) is prevented extremely safely by means of the double locking arrangement. This means that even if there is a power outage, etc., in the vehicle, unintentional opening of sliding doors (11A and 11B) can be prevented due to wind pressure, etc.

To switch from the locked state described above to the unlocked state and to open the sliding doors (11A and 11B), simply operate the central gear (21) by means of the electric motor in the opposite direction to that of the closing process. In the locked state (figures 4 and 5), since the sliding doors (11A and 11B) are blocked by the coupling elements (66A and 66B), the rotation of the gear is prevented

(22)

 internal. In the meantime, movement of the blocking sliding element (33) in an unlocking direction (direction indicated by an arrow (A2) in Figures 3 and 5 is avoided, hereinafter referred to as "unlocking address (A2) ”) Simply by the impulse force of the locking spring (73). That is, in this state, if a driving force that opposes the impulse force of the locking spring (73) is transmitted to the blocking sliding element (33), the blocking sliding element (33) can move in the Unlocking address (A2). Therefore, when, from the locked state, the gear is operated

(twenty-one)

 central in the opposite direction to that of the closing process, all the driving force of the central gear (21) is transmitted to the carrier (23) and the sliding sliding element (33) is moved, by means of the traction element (70) , in the unlocking direction (A2) against the impulse force of the locking spring (73). According to this movement of the locking slide element (33) in the unlocking direction (A2), the guide coupling bolt (63c) of the linkage mechanism moves along the edge of the groove (33e) from the first

hole part (A) to the second hole part (B) and thus the link mechanism (61) passes from the rectilinear state to the flexed state. In this way the hooks of the second parts (68A and 68B) of engagement of the elements (66A and 66B) of engagement with the bolts (63d and 63e), located at the ends of the link mechanism (61) are released. Then, by means of the elastic tensile force of the coupling spring (69) that couples the pair of coupling elements (66A and 66B), the coupling elements (66A and 66B) receive a force that causes the first parts (67A and 67B) of hitch are directed outward (towards sides opposite the link mechanism (61)). That is, the engagement elements (66A and 66B) receive a force that rotates the elements in the directions (R2) in Figure 5. In this way, the locking bolts (14A and 14B) are allowed, which are in states engaged with the second parts (68A and 68B) of engagement, move in the opening directions (B2) and the blocking of the sliding doors (11A and 11B) is released.

In the position shown in Figure 2, the movement of the locking slide element (33) in the unlocking direction (A2) is limited by the deformation limit of the locking spring (73). The limitation of the movement of the locking slide element (33) in the unlocking direction (A2) is not limited to the limitation by the deformation limit of the locking spring (73) and instead the limitation can be applied by contact of the carrier (23) and the base (5) in a predetermined position. In addition, the lengths of the guide notches (80A and 80B), into which the bolts (63d and 63e) of the link mechanism (61) are inserted, can be properly set so that the deformation of the mechanism (61) of The link is limited by the limitation of the movement of the bolts (63d and 63e) by means of the guide notches (80A and 80B) and the movement of the sliding element (33) is limited accordingly.

As a result of the limited movement of the blocking element (33) in the unlocking direction (A2), the driving force of the central gear (21) in the planetary gear mechanism (20) is now transmitted to the gear side (22) internal. The sliding doors (11A and 11B) are therefore operated in the opening directions (B2) by the rack and pinion mechanism (10). In this process, since the coupling elements (66A and 66B) receive a force that rotates the elements to the unlocked positions (force in the directions (R2) in Figure 5) from the coupling spring (69), the elements (66A and 66B) of engagement do not limit the movements of the locking bolts (14A and 14B) that are fixed with respect to the sliding doors (11A and 11B).

An arrangement in which the locking element and lever (33) not illustrated, arranged in a position accessible from inside or outside of the vehicle, are connected by means of a non-illustrated cable or other coupling element, can be provided to allow a person operates the lever in an emergency to move the sliding slide in the release direction to release the lock and then open the sliding doors (11A and 11B) manually. As a more simplified arrangement, the lever can be fixed directly to the sliding slide element (33).

A case will now be described in which the sliding resistance of at least one of any of the sliding doors (11A and 11B) becomes significantly large during the closing operation of the sliding doors (11A and 11B) (during movements of the sliding doors from the fully open position to the fully closed position) using figures 8 and 9. This corresponds, for example, to a case where a passenger is trapped by the sliding doors (11A and 11B) or a case in which a passenger collides with one of the sliding doors. Figure 8 is a schematic view of a state of the carrier (23) during a normal closing operation. Figure 9 is a schematic view of a state of the carrier (23) when the sliding resistance of a sliding door increases during the closing operation.

When the closing operation of the sliding doors (11A and 11B) is performing normally, that is, when both of the sliding doors (11A and 11B) are operating at the normal sliding resistance without obstruction of movement from the outside, the driving force of the central gear (21) is transmitted to the internal gear side (22) and the sliding doors (11A and 11B) are operated in the closing directions (B1) by the rack and pinion mechanism (10) such as described above. This is because, as mentioned above, the movement of the sliding slide element (33) is limited when the sliding doors (11A and 11B) are in positions other than the fully closed position. That is to say, the foregoing is due to the fact that the traction element (70), coupled to the carrier (23), is driven by the torque (71) torque limiter at the predetermined elastic force that can suppress the rotation of the carrier ( 23) in the state in which the movement of the blocking element (33) is limited. With the present embodiment, the elastic force that suppresses the rotation of the carrier (23) is caused to act on the carrier (23) by means of the traction element (70) to balance with the sliding resistance of the doors (11A and 11B) sliders That is, when during the closing operation, a force not less than the normal sliding resistance acts on the sliding door (11A or 11B), the carrier (23) can rotate to enter the state shown in Figure 9 while elastically deforms the torque-limiting spring (71) while keeping the position of the sliding element (33) fixed.

A permanent magnet (83) is fixed to an outer peripheral edge of the carrier (23), and a detection switch (84) (collision detection unit, limit switch), mounted on the base side (5), is arranged to be switched by the movement of the permanent magnet (83) according to the rotation of the carrier (23).

Specifically, the detection switch (84) is in the OFF state in the position of the carrier (23) during operation of the sliding doors (11A and 11B) at normal travel resistance. On the other hand, when the carrier (23) rotates a predetermined amount according to an increase in the sliding resistance of the sliding doors (11A and 11B), the detection switch (84) is set to the ON state (see). Figure 9). When the detection switch (84) is switched to the ON state, a signal that stops the drive to the electric motor is transmitted and the drive of the electric motor is stopped.

By the above description, when, during the closing operation of the sliding doors (11A and 11B), the sliding resistance in the closing directions (B1) of the sliding doors increases due to the fact that a passenger becomes engaged or one of the the sliding doors of the sliding separation type sliding doors collide with a passenger, etc., the electric motor drive can be stopped to relax the impact force applied to the passenger hooked by the sliding doors (11A and 11B), etc. The action taken when the detection switch (84) is set to the ON state (when the collision or the hitch is detected by the door) is not limited by the stopping of the electric motor drive and instead a control can be performed to reduce the drive output of the electric motor.

The arrangements are made so that when the sliding doors (11A and 11B) are in the fully closed position, the signal described above to stop the electric motor drive is not transmitted or the electric motor drive does not stop even if the signal. Therefore, the electric motor drive is not stopped during the movement operation of the blocking slide element (33) in the blocking direction (A1).

An arrangement is also possible in which, for example, a locked state detection sensor is provided which detects that the sliding doors are in a locked state and if after the detection signal is transmitted from the switch (84) of detection, a detection signal of the blocked state detection sensor is not transmitted within a predetermined time, it is determined that a collision has occurred

or a hitch by the door, etc., by sliding doors and the electric motor drive stops. In addition, for example, a deceleration sensor that detects the deceleration of the sliding doors in combination can be used. In this case, when the movement speeds of the sliding doors are high in the closing operation, a collision or a hitch can be determined by the door, etc., by detecting the rotation of the carrier by means of the detection switch (84), and When the sliding doors have approached the closed position and the movement speeds of the sliding doors have become slow, a collision or a hitch by the door, etc., can be detected by the deceleration sensor.

As described above, the locking and opening apparatus according to the present embodiment includes: the rack and pinion mechanism (10), which has the pair of zippers (7A and 7B), respectively mounted on the pair of doors ( 11A and 11B) sliding separation type sliders that can move reciprocally with respect to the housing (wall surface), and a pinion (9) engaged with the pair of zippers (7A and 7B); the electric motor, which functions as a source of opening / closing of the sliding doors (11A and 11B); the locking mechanism (60) mounted on the base (5) fixed to the housing and allowing the pair of sliding doors (11A and 11B) to be locked in the fully closed position by limiting the respective movements of the locking bolts (14A and 14B) which are respectively fixed to the respective sliding doors of the pair of sliding doors (11A and 11B); the blocking slide element (33) for switching the blocking mechanism (60) between the locked state and the unlocked state; and the planetary gear mechanism (20), which has the central gear (21), into which the driving force of the electric motor is introduced, the internal gear (22), which allows the driving force to be emitted to the pinion (9 ), and the carrier (23), which allows the actuation force to be emitted to the blocking element (33); and is arranged so that when the sliding doors (11A and 11B) are in the fully closed position, the driving force is emitted from the carrier (23) to the sliding sliding element (33).

With the previous arrangement, given that the movements of the locking bolts (14A and 14B), which are respectively fixed to the respective sliding doors of the pair of sliding doors (11A and 11B), are respectively limited by means of the mechanism (60) of lock, each of the pair of sliding doors (11A and 11B) can be locked independently. Therefore, even when the rack and pinion mechanism (10) malfunctions, the movements of both sliding doors (11A and 11B) can be maintained in the locked state. On the contrary, when the rack and pinion mechanism (10) operates normally, although the blocking of a sliding door (11A (11B)) is released due to malfunction, etc., since the door (11A (11B)) sliding is coupled to the other door (11B (11A)) sliding by means of the rack and pinion mechanism (10), provided that the blocking of the other sliding door (11B (11A)) is effective, the door (11A (11B) ) Slider can be kept in the locked state. Therefore, sliding doors (11A and 11B) of sliding separation type can be locked more securely.

Also with this arrangement, the power of the electric motor is assigned by means of the planetary gear mechanism (20) to drive the pinion (9) of the rack and pinion mechanism (10) on the one hand and to drive sliding element (33) of sliding lock by other side. Since the provision for the transmission (allocation) of power from the

electric motor is therefore housed in a compact space, the structure can be simplified and an opening and closing apparatus with compact locking can be provided.

In addition, since the driving force from the electric motor is assigned using not a damping spring as in patent document 1 but a planetary gear mechanism (20), even if the driving force is lost due to engine malfunction electric, etc., in the state in which the sliding doors (11A and 11B) are locked in the closed position, a force is not applied in a direction of release of the lock to the sliding element (33) of the lock, etc., and unintentional unlocking is avoided.

In addition, the opening and closing apparatus with lock according to the present embodiment has the sliding slide element (33) which allows the locking mechanism (60) to be switched between the locked state and the unlocked state moving according to the carrier drive (23) . The locking mechanism (60) is arranged so that the movement of the sliding sliding element (33) is prevented when the sliding doors (11A and 11B) are in positions other than the fully closed position and the movement of the element (33) Sliding lock is allowed when the sliding doors (11A and 11B) are in the fully closed position.

With this arrangement, since the movement of the sliding sliding element (33) is avoided when the sliding doors (11A and 11B) are in positions other than the completely closed position, the blocking operation is performed when the doors (11A and 11B ) Sliders have reached the fully closed position safely. That is to say, the blocking operation is prevented at a time that is too early in the operation of the sliding doors (11A and 11B) in closing directions (B1), and in this way the breakage of the mechanism ( 60) Locking and limiting the sliding doors (11A and 11B) before reaching the fully closed position.

Also with the opening and closing apparatus with locking according to the present embodiment, the locking mechanism (60) includes the linking mechanism (61), which can deform to the rectilinear state and to the flexed state according to the movement of the sliding element (33) locking, and the link retention mechanism (65), which retains the link mechanism (61) in the flexed state when the sliding doors are in positions other than the fully closed position. With the locking mechanism (60), when the sliding doors (11A and 11B) are in the fully closed position, the link mechanism (61) deforms to the rectilinear state and thereby limits the movement of the bolts (14A and 14B) lock respectively fixed to the sliding doors (11A and 11B).

With this arrangement, the movements of the sliding doors (11A and 11B) can be locked in the completely closed position by placing the link mechanism (61) in the rectilinear state, and given that in positions other than the completely closed position the mechanism (61 ) The link is maintained in the flexed state by means of the link retention mechanism (65), the blocking operation is performed after the sliding doors (11A and 11B) have reached the fully closed position. Therefore, the locking mechanism (60) can be formed in a compact manner because it is operated using the link mechanism (61) and a stable drive can be performed because the locking mechanism (60) is mechanically actuated.

Also, the opening and closing apparatus with locking according to the present embodiment, has locking bolts (14A and 14B) that are fixed to the sliding doors (11A and 11B) to extend in vertical directions. The retention mechanism (65) is constituted by the pair of coupling elements (66A and 66B), which have the first coupling parts (67A and 67B), rotatably installed near the respective ends of the mechanism (61) of linkage and that engage with the locking bolts (14A and 14B) in the fully closed position, and the second engagement parts (68A and 68B), which engage with the ends of the link mechanism (61) in the rectilinear state in the fully closed position. The coupling elements (66A and 66B) prevent the movement of the blocking element (33) preventing the transition of the mechanism

(61) of connection to the rectilinear state when the sliding doors (11A and 11B) are in positions other than the completely closed position, and allow the movement of the blocking sliding element (33) when driven by the bolts (14A and 14B) of locking to rotate to positions that allow the coupling of the ends of the link mechanism (61) with the second parts (68A and 68B) of engagement during the movement of the sliding doors (11A and 11B) in the closing directions (B1) .

With this arrangement, in the fully closed position, the engagement elements (66A and 66B) are engaged with the locking bolts (14A and 14B). Then, by extending the link mechanism (61) to the rectilinear state, the engagement elements (66A and 66B) engage with the ends of the link mechanism (61) and are limited in terms of rotational movement. The locking bolts (14A and 14B) are thus limited in terms of movement in the state of being engaged with the engagement elements (66A and 66B). Therefore, by means of the coupling elements (66A and 66B), the transition of the link mechanism (61) to the rectilinear state in positions other than the completely closed position can be prevented and the movement of the bolts (14A and 14B) of lock in fully closed position. Therefore, the number of parts necessary to form the locking mechanism (60) can be made small and a more compact locking mechanism (60) can be arranged.

Also, the opening and closing apparatus with locking according to the present embodiment includes the sliding sliding element (33), which allows sliding movement in one direction with respect to the locking mechanism (60) and having a groove (33e) curved in the lower surface, the link mechanism (61) acts within a plane parallel to the bottom surface of the sliding slide element (33) and has the guide coupling bolt (63c), arranged at a point of coupling, inserted in the groove (33e), and the link mechanism (61) is deformed to the rectilinear state and to the flexed state by means of the guide coupling bolt (63c) that moves along the groove (33e).

With this arrangement, the link mechanism (61) can be deformed to the rectilinear state and to the flexed state by movement of the blocking sliding element (33) in one direction without interposing another element between the blocking sliding element (33) and the mechanism (61) link. Therefore, the installation space of the locking mechanism (60) can be made small.

The locking mechanism (60) has the link mechanism (61), which can be deformed to the rectilinear state and to the bent state within the horizontal plane, and by the link mechanism (61) that deforms to the rectilinear state when the doors ( 11A and 11B) sliders are in the fully closed position, the mechanism

(60)

 Locking engages with the locking bolts (14A and 14B) that are fixed to the sliding doors (11A and 11B) and enters the locked state.

With this arrangement, when the sliding doors (11A and 11B) reach the fully closed position, the sliding doors (11A and 11B) can be locked by operating the sliding element (33) locking mechanism and deforming the link mechanism (61) to the state rectilinear within the horizontal plane. Since the mechanism

(60)

 locking device therefore places the sliding doors (11A and 11B) in the locked state using the mechanism

(61)

 of linkage that works within the horizontal plane, the mechanism installation space can be made

(60)

 Lock is small in the height direction. Therefore, using the opening and closing apparatus with lock according to the present embodiment, the opening / closing and locking operations can be performed within a smaller installation space.

With the opening and closing apparatus with locking according to the present embodiment, the link mechanism (61) has the link (62a), rotatably fixed to the base (5), and the movements of the bolts (63d and 63e) at the ends of the link mechanism (61) they are limited by the rectilinear guide notches (80A and 80B) formed in the base (5).

With this arrangement, by rotatingly fixing the link part (62a) that is a part of the link mechanism (61) to the base (5), the position of the link mechanism (61) can be fixed with respect to the base ( 5) without obstructing the operation of the link mechanism (61). The movements of the bolts (63d and 63e) at the ends of the linkage mechanism (61) can be limited to straight lines by the notches (80A and 80B) of the base guide (5), and the linkage mechanism (61) which can be deformed to the rectilinear state and to the bent state can be deformed by a simple arrangement.

The opening and closing apparatus with locking according to the present embodiment has the locking bolts (14A and 14B) that are fixed to the sliding door so that they extend in vertical directions. The locking mechanism (60) includes coupling elements (66A and 66B), rotatably installed within a horizontal plane near the ends of the linking mechanism (61) and having the first coupling parts (67A and 67B) , which are engaged with the locking bolts (14A and 14B) in the fully closed position, and the second coupling part (68A and 68B), which is engaged with the bolts (63d and 63e) at the ends of the mechanism (61 ) in the rectilinear state in the fully closed position.

With this arrangement, by extending the locking bolts (14A and 14B) in the vertical directions from the sliding doors (11A and 11B), the locking mechanism (60) operating within the horizontal plane can be easily engaged with the bolts. (14A and 14B) lock. Since in the fully closed position, the movements of the locking bolts (14A and 14B) can be limited by limiting the rotations of the engagement elements (66A and 66B) by means of the bolts (63d and 63e) at the ends of the mechanism (61 ) of the link in the rectilinear state, the direction in which the link mechanism (61) extends to the rectilinear state can be fixed to any direction that allows the limitation of the rotation of the engagement elements (66A and 66B). As shown in Figure 5, with the present embodiment, the forces that receive the bolts (63d and 63e) at the ends of the link mechanism (61) due to the rotations of the engagement elements (66A and 66B) are perpendicular to the longitudinal directions of the guide notches (80A and 80B), in which the bolts (63d and 63e) can move, and the forces applied from the engagement elements (66A and 66B) are supported by the edges of the guide notches (80A and 80B). Therefore, these forces do not act to make the mechanism

(61) the link goes to the flexed state and therefore the locked state can be maintained more securely. Also in this case, the loads applied to the links (62b and 62c) become small and the malfunction, etc., of the link mechanism (61) can be suppressed.

Also, the opening and closing apparatus with locking according to the present embodiment has the sliding sliding element (33) that can move within the horizontal plane according to the actuator of the carrier (23). The mechanism

(61) the link can be deformed to the rectilinear state and to the flexed state by the movement of the guide coupling bolt (63c), arranged at the coupling point of the link mechanism (61), according to the movement of the sliding element (33) lock

With this arrangement, since the sliding slide element (33) can move within the horizontal plane, the installation space can be made small in the height direction. In addition, the blocking slide element (33) can switch the state of the link mechanism (61) by using the guide coupling bolt (63c) that constitutes the link mechanism (61), and thus an arrangement can be made Simple with a small number of pieces.

Also, the opening and closing apparatus with locking according to the present embodiment has the sliding sliding element (33) which allows sliding movement in a direction within the horizontal plane according to the actuator of the carrier (23) and has the groove (33e ) in a curved way on the bottom surface. The guide coupling bolt (63c), disposed at a coupling point of the linkage mechanism (61), is inserted into the groove (33e), and the linkage mechanism (61) can deform to the rectilinear state and to the flexed state by means of the guide coupling bolt (63c), arranged at the coupling point of the linkage mechanism (61), which moves along the groove (33e) according to the movement of the blocking sliding element (33).

With this arrangement, the movement of the link mechanism (61) can be limited by using the groove (33e) on the lower surface of the sliding slide element (33) which allows sliding movement within the horizontal plane. Since the groove (33e) has a curved shape, an arrangement that guides the guiding coupling bolt (63c) in a direction that differs from the direction of movement of the blocking sliding element (33) can be made simple. With the present embodiment, the deformation of the mechanism

(61) of connection to the rectilinear state and the flexed state can be realized by means of the second orifice part (B) which extends in a curve in a direction that differs from the direction of movement of the blocking sliding element (33).

Also, the lock-open and close apparatus according to the present embodiment includes the torque-limiting spring (71) which causes the predetermined elastic force, which suppresses the rotation of the carrier (23) when the sliding resistance of the doors (11A and 11B) sliding is less than the predetermined sliding resistance, acting on the carrier (23) during the closing operation of the sliding doors (11A and 11B), and the detection switch (84) provided in the base (5) and stops the electric motor drive when the amount of deformation of the spring (71) torque limiter reaches a predetermined amount of deformation during the closing operation of the sliding doors (11A and 11B). In this case, the carrier (23) is allowed to emit the driving force of the electric motor to the torque (71) torque limiter.

With this arrangement, if during the closing operation of the sliding doors (11A and 11B) (during the movement of the sliding doors (11A and 11B) from the fully open position to the fully closed position), the sliding resistance of the sliding doors (11A and 11B) is less than the predetermined sliding resistance, since the rotation of the carrier (23) is suppressed by the elastic force of the torque limiting spring (71), the driving force of the electric motor is it transmits from the internal gear (22) to the pinion (9) and the closing operation of the sliding doors (11A and 11B) is performed. During the closing operation of the sliding doors (11A and 11B), a passenger gets caught or a sliding door (11A or 11B) collides with a passenger, a force not less than the normal sliding resistance is applied to the doors ( 11A and 11B) sliders, and if the predetermined displacement resistance is exceeded, the carrier (23) rotates against the elastic force of the torque (71) torque limiter and the torque (71) torque limiter undergoes a deformation elastic When the amount of elastic deformation reaches the predetermined amount, the electric motor drive is stopped by the detection switch (84). Since the detection switch (84) is arranged in the base (5), fixed to the housing side, such as the electric motor, a door hitch or collision can be detected during the closing operation of the sliding door without complicate the wiring. With this arrangement, collision detection is allowed regardless of whether the sliding doors (11A and 11B) are accelerating or decelerating and collision detection can be performed throughout the entire range of motion of the sliding doors (11A and 11B) .

Also, the opening and closing apparatus with locking according to the present embodiment has the sliding sliding element (33) that can switch the locking mechanism between the locked state and the unlocked state by movement. The torque limiter spring (71) is disposed between the carrier (23) and the element

(33) sliding slide.

With this arrangement, the output of the carrier (23) can be used to drive the blocking slide element (33) to switch the blocking mechanism (60) and cause a force to act on the torque limiting spring (71) to the Same time. Therefore, for example, in a case where the torque-limiting spring (71) is installed in another position, the driving force of the carrier (23) in the switching of the mechanism (60) of

Locking is assigned in parallel between the spring (71) torque limiter, which is installed in the other position, and the sliding element (33). The forces acting respectively on the respective components become small. However, by installing the torsional torque limiting spring (71) between the carrier (23) and the locking sliding element (33) as in the present embodiment, the force applied to the torque limiting spring (71) is also caused of torsion acting on the sliding element (33) in series lock, thus allowing collision detection and blocking operation to be carried out efficiently.

With the opening and closing apparatus with locking according to the present embodiment, the detection switch (84) is constituted by a limiting switch that stops the electric motor from driving after detecting that the angle of rotation of the carrier (23) has become non less than a predetermined rotation angle.

With this arrangement, the limit switch detects the angle of rotation of the carrier (23), which rotates in correspondence with the deformation of the torque limiting spring (71), to stop the drive of the electric motor. Therefore, the collision detection unit can be arranged with a simple arrangement.

Also with the opening and closing apparatus with locking according to the present embodiment, the torque-limiting spring (71) causes the predetermined elastic force, which suppresses the rotation of the carrier (23), to act on the carrier (23) for balance with the sliding resistance when the sliding doors (11A and 11B) are performing the normal closing operation.

"Performing a normal closing operation" refers to a state in which a force that obstructs the operation of the sliding doors (11A and 11B) is not acting from the outside, and the elastic force is made that is balanced with the travel resistance during this normal closing operation act on the carrier

(2. 3)

 by means of the spring (71) torque limiter. Therefore, the elastic force that is caused to act by means of the torque-limiting spring (71) is made to be smaller. Therefore, the torque limiting spring (71) can be installed in an easily deformable state. Since this makes the torque-limiting spring (71) more easily deformable by increasing the sliding resistance of the sliding doors (11A and 11B), a higher sensitivity detection is allowed. In addition, the arrangement uses the planetary gear mechanism and therefore when the sliding door (A or B) collides, because the force corresponding to the elastic force of the torque limiting spring (71) acts on the object of collision, causing The elastic force that is caused to act by means of the small torque limiting spring (71), the impact applied to the collision object from the sliding door (A or B) can be significantly relaxed.

That is, various variations are possible, such as the coupling of the central gear (21) to the pinion (9) and the coupling of the internal gear (22) to the electric motor, etc.

(2)

Although in the embodiment described above, the coupling between the sliding slide element and the link mechanism is constituted by the slot part, formed on the lower surface of the blocking slide element, and the coupling bolt of the link mechanism, the The present invention is not limited to this. For example, as shown by an unlocked state illustrated in Figure 10 and a locked state illustrated in Figure 11, a roller coupling bolt (33f) can be fixed to the bottom surface of the sliding slide element (33) and The central link of the link mechanism (61) can be arranged as a link (62a '), with a shape that can be rotated after being driven by the roller coupling bolt (33f) according to the movement of the blocking sliding element (33). Thus, the link mechanism (61) can be deformed to the flexed state and to the rectilinear state according to the movement of the blocking sliding element (33) as described with the embodiment.

(3)

 Although with the embodiment described above, the carrier and the sliding slide element are coupled with the traction element and the torsion-limiting spring interposed between means, instead the carrier can be directly coupled to the sliding sliding element.
