[0001] MOVABLE OBJECT ASSISTANCE DEVICE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assistance device for a movable body that assists in the operation of various movable bodies.

There is known an assisting device for a movable body which performs forced movement using a pushing-out mechanism in order to assisting the operation of the movable body such as a sliding door or an eavesdropper. In this assisting device of the movable body, a keeper is provided on the door frame side and a contact member capable of engaging with the keeper is provided on the sliding door side. The abutment body is slidable in the standby position and the retracted position, and is connected to a tension coil spring as a push-up mechanism. The abutment body has, for example, a resin-made engaging portion at a tip end, and the engaging portion is engageable and disengageable with the keeper.

When the sliding door is in the open position where the door is not closed, the abutment body is held in the standby position in the state in which the tension coil spring is stretched to the greatest extent. When the operator moves the sliding door to the closing position from the opening position, the abutment body hits the keeper in the middle, thereby catching the keeper. At the same time, the holding at the standby position is released and the abutment body is pulled by the tension coil spring with the keeper catching and moved toward the retracted position. Therefore, the sliding doors of the moving dimensions are forcibly moved.

When the sliding door is in the closed position, the abutting body is in a state of compressing the tension coil spring. When the operator moves the sliding door toward the opening position from the closed position, the sliding door is moved while pulling the tension coil spring. Upon reaching the predetermined position, the abutment body opens the keeper, and is held at the standby position again.

A partition plate 25 is provided at the center of the rear portion of the housing 21 in the Z direction and an upper chamber 25a and a lower chamber 25b on the upper side are formed. One end side of the upper chamber 25a is opened and the latch base 31 is accommodated between the side walls 21a and 21a sandwiching the upper chamber 25a. In each drawing, a part of the housing 21 is cut out to show a cross section for the sake of explanation of the internal structure.

On one end side of the side walls 21a, 21a of the housing 21, a slit 27 (guide path) is provided. The slit 27 has a main guide path 27a extending along the X axis to reach a standby position (first position) and a retracted position (second position), and a main guide path 27a extending from the front end And an escape path 27c branched from the retracted position of the rear portion of the main guide path 27a and curved downward and forward is formed continuously As shown in FIG.

The atmosphere path 27b follows an arc-shaped trajectory T2 about the first axis portion 32b in a state where the latch 22 is in the first position, and in the engagement and disengagement operation, (32d) along the arc-shaped trajectory (T2). The retracting passage 27c overlaps the groove 31b forming the locus T2 of the arcuate shape of the support piece 31c and forms a path for guiding the first shaft portion along the arc locus at the retracting operation.

The slit (27) is rotatably coupled to a second shaft portion (32d) formed at the front end of the latch (22). The first shaft portion 32b is rotatably and slidably engaged with the second shaft portion 32d of the slit 27 at a position rearward of the second shaft portion 32d. The projection 31a of the latch base 31 is slidably engaged with the main guide path 27a of the slit 27. [

A connecting portion 21b for fixing the end portion of the tension coil spring 41 to the housing 21 is formed in the lower chamber 25b of the housing 21. [ The connecting portion 21b is, for example, a shaft-shaped member extending between the side walls 21a and 21a. The other end of the tension coil spring 41 is mounted on the connecting portion 21b.

3 to 7, the latch 22 includes a latch base 31 (base), a cam 32 rotatably connected to the distal end of the latch base 31, And a regulating slider 33 (regulating member) for regulating the regulating member 33. The regulating slider 33 is movably supported between the side walls 21a and 21a in the housing 21 in the X-axis direction.

The latch base 31 has a protruding portion 31a which is elongated in the X direction. The latch base 31 is slidably held in the X direction between the pair of side walls 21a and 21a forming the upper chamber 25a of the housing 21 by engagement of the protrusion 31a with the slit 27 do. The latch base 31 is provided at its distal end with a support piece 31c having a groove 31b which overlaps with the retraction passage 27c and forms an arc-shaped locus.

The cam 32 has a pair of first shaft portions 32b having axial centers C1 along the Y direction and projecting in the Y direction. The first shaft portion 32b is inserted into the slit 27 and the groove 31b to be rotatable and movably coupled within the slit 27. [

As shown in Fig. 7, the cam 32 is rotatably provided around the first shaft portion 32b in the first rotation direction R1 and the second rotation direction R2 opposite thereto. The cam 32 has a catcher 32a, a nipping piece 32c, a regulating protrusion 32g (regulating engagement portion), a push-fit portion 32e, And a pair of second shaft portions 32d.

The catcher 32a has a pair of hooks 32f provided on the tip end side of the cam 32 and projecting in the R1 direction. The hooks 32f are respectively provided on both sides in the Y direction and have a triangular plate-shaped member.

The nipping pieces 32c are protruded upward from the rear portion of the cam 32. [ The engaging piece 32c is disposed on the rear side of the pressure-receiving portion 33b in a state of engagement with the striker 10 and has a trapezoidal space between the engaging piece 32c and the hook 32f, So as to be sandwiched between them.

The regulating protrusion 32g protrudes on both sides in the width direction at the rear end of the cam 32 and is slidably engaged along the guide surface 33e of the regulating slider 33. [ The regulating protrusion 32g is guided along the guide surface 33e of the regulating slider 33 so as to regulate the position and posture of the cam 32 to control the turning operation.

The pair of second shaft portions 32d are formed in the catcher 32a and have an axis C2 along the Y direction and protrude in the Y direction and are movably coupled in the slit 27. [

The push-out portion 32e is provided at the lower portion of the cam 32 and is positioned rearward and further below the second shaft portion 32d. The push-out portion 32e is disposed at the lower portion of the housing 21, and one end of the tension coil spring 41 is connected. And the push-out portion 32e is always pulled in the pull-in direction by the tension coil spring 41.

The restricting slider 33 includes a slide projection 33a slidably engaged with the guide groove 31e of the latch base 31, a pressure-receiving portion 33b pressed against the striker 10, A regulating guide portion 33c for regulating the position of the regulating protrusion 32g of the first and second regulating members 32 and 32 and a recessed portion into which the regulating protrusion 32g of the regulating protrusion 32g can enter.

The restricting slider 33 is disposed between the pair of support pieces 31a of the latch base 31 and is engaged with the latch base 31 in the X direction As shown in Fig.

The pressure-receiving portion 33b is disposed at the upper portion of the front end of the regulating slider 33 and abuts against the pressing surface 12a of the striker 10 by the movement of the sliding door M and is pressed in the drawing-in direction. The pressure-receiving portion 33b is provided with a cushioning material 33f made of an elastic material such as rubber or the like, and has a buffering function when abutting against the striker 10. [

The concave portion is formed behind the pressure-receiving portion 33b. So that the nipping pieces 32c can enter the concave portion. The holding piece 32c is disposed on the rear side of the pressure receiving portion 33b and the pressure receiving portion 33b and the engaging projection 12 are arranged side by side in a space in a trapezoidal shape between the hook 32f and the holding piece 32c So that it is sandwiched.

The regulating guide portion 33c is constituted by the lower edge of the regulating slider 33 and constitutes a guide surface 33e along a predetermined locus T1 (first locus). The guide surface 33e has a predetermined curved shape and has a locus T2 in which the second shaft portion 32d is moved in the atmosphere path 27b of the guide path 27 and a locus T2 of the locus of the tip of the hook 32f The engagement and disengagement operations are set to be gentle and smoothly performed in the relationship with the contact surface T3. The position of the regulating projection 32g is regulated along the locus T1 to regulate the position and posture of the cam 32 to control the turning operation of the cam 32. [

As an example of the condition of the locus T1, the regulating protrusion 32g is guided along the locus T1 so that the locus T3 of the tip of the cam 32 (hook) is formed along the outer shape of the striker 10, and is set so that the clearance between the cam 32 and the striker 10 is always minimized. Further, when the second shaft portion 32d moves along T2, the rotation of the cam 32 is prevented so that the cam 32 is not vigorously rotated at the curved apex portion, which is likely to rapidly rotate due to the force of the tension spring 41 And is set to a condition for operating at a low speed in accordance with the movement of the sliding door M. The engaging portion 12 of the striker 10 is disposed in the space between the hook 32f and the nipping piece 32c and is engaged without any clearance before the regulating force is relaxed so that the engaging action is gradually performed to alleviate the restricting force The braking force of the braking mechanism 24 is generated before the time point.

The push-up mechanism 23 is constituted by a tension coil spring 41 as a first pushing means. The tension coil spring 41 is disposed in the lower portion of the housing 21 such that the axial direction thereof follows the sliding direction. One end of the tension coil spring 41 is connected to the pushing portion 32e of the lower portion of the latch 22 and the other end is connected to the connecting portion 21b of the housing 21. [ The tension coil spring 41 has a function of holding the latch 22 in the waiting state by pushing it in the pulling direction and holding it in the atmosphere path 27b and a function of holding the latch 22 in the main guide path 27a And a function of pushing the latch 22 in the second rotating direction R2.

The braking mechanism 24 includes a piston damper 50 provided in an upper chamber 25a of the housing 21. [ The piston damper 50 includes a cylinder 51 in which a fluid is enclosed and a piston reciprocating on the slide axis X of the latch 22 in the cylinder 51 and a piston rod 52). The end of the piston rod 52 is fixed to the housing 21 and the outer end of the cylinder 51 opposed to the piston is connected to the rear end of the latch 22. [

The braking mechanism 24 applies a resistance force against the press-fitting and the tensioning operation of the cylinder 51 or the piston rod 52 by operating the fluid opposing the fluid in the cylinder 51 to the operation of the piston housed in the cylinder 51 Thereby braking the slide operation of the latch 22 with respect to the housing 21. [ As a fluid to be sealed in the cylinder 51, a viscous fluid such as silicone oil is typically used, but the present invention is not limited thereto, and a gas may be used.

Hereinafter, the operation of the assist device 1 according to the present embodiment will be described with reference to Figs. 8A to 10D.

In the first state in which the sliding door M does not reach the striker 10 as shown in Figs. 1 and 8A, the second shaft portion 32d of the latch 22 is moved to the atmosphere path 27b And is retained by being pulled by the tension coil spring 41. The latch 22 is held at the standby position of the end of the housing 21. [

The first operation from the first state to the second state will be described. When the sliding door M reaches the first predetermined position as shown in Fig. 8 by moving the sliding door M toward the left door stop F1 from the first state, The slider 33 is brought into contact with the striker 10. Then, the striker 10 presses the pressure-receiving portion 33b backward, and the regulating slider 33 is pushed rearward (right side in Fig. 8). The regulating slider 33 is moved rearward and the regulating protrusion 32g of the cam 32 is gradually moved backward and downward along the guide surface 33e of the regulating slider 33, The cam 32 is rotated in the direction R1.

At this time, as shown in Figs. 10A to 10D, the restricting projection 32g engaged with the guide surface 33e is guided along the predetermined trajectory T1 rearward and downward. The locus T1 of the guide surface 33e is set so that the rapid rotation of the cam 32 is suppressed in the vicinity of the second shaft portion 32d passing the bent apex of the slit 27, .

An example of the condition of the locus T1 is set such that the movement locus T3 of the tip of the cam 32 enters the first engagement concave portion 12b along the shape of the engaging projection 12 to reduce the clearance . The regulating force by the guide surface 33e is set to be insufficient until the second shaft portion 32d enters the main guide path 27a from the atmosphere path 27b and the second shaft portion 32d is set to the atmosphere path 27b To the main guide path 27a, the regulating force is relaxed. Under such a condition, since the engaging portion 12 of the striker 10 is already disposed in the space between the hook 32f and the holding piece 32c at the time when the restraining force is relaxed, there is no clearance and no collision occurs , And the impact sound can also be reduced. At the time when the restricting force is relaxed, the bending portion, which is likely to be rotated rapidly due to the force of the tension spring 41, has already passed and reaches the straight main guide path 27a, and the operation of the braking mechanism 24 is started Since the braking force is generated, the operation is performed smoothly and gradually.

8, the hook 32f at the tip of the cam 32 is engaged with the striker 10, and the striker 10 is caught by the latch 22. As a result, At the same time that the cam 32 is rotated in the R1 direction and the lower second shaft portion 32d is moved upward and reaches the position where it enters the main guide path 27a, the holding on the atmosphere path 27b is released , And is movable along the slide axis X which is the center line of the main guide path 27a.

8, the latch 22 is relatively moved to the right with respect to the housing 21 and the sliding door M by the restoring force of the tension coil spring 41, and is relatively moved to the retracted position. The sliding door M and the housing 21 are forced to move relative to the door frame F and the striker 10 relatively to one side in the sliding direction. At this time, resistance force is applied by the braking mechanism 24, and the sliding door M is automatically moved in a closing direction while being fully charged.

Next, the second operation from the second state shown in Figs. 2 and 8 to the first state will be described. In this second operation, as opposed to the first operation, the operation is performed in the order of FIG. 8 (d), (c), (b), and (a). When the sliding door M is moved to the right from the second state in which the sliding door M is completely moved to the left end position, the latch 22 is pressed against the urging force of the tension coil spring 41 The sliding door M is moved to the right side while the striker 10 is caught while relatively moving toward the one end side with respect to the sliding door M and the housing 21 (Fig. 8). At this time, since the rear end of the latch 22 is connected to the piston rod 52 of the piston damper 50, the resistance of the fluid in the cylinder 51 is received while moving the piston.

The striker 10 is moved away from the pressure-receiving portion 33b and the cam 32 is rotated about the first axis 32b by the restoring force of the tension coil spring 41 as shown in Fig. Lt; / RTI >

At this time, as shown in Fig. 10, the regulating protrusion 32g, which is engaged with the guide surface 33e, is guided along the predetermined trajectory T1 rearward and downward. The position of the regulating protrusion 32g is regulated along the locus T1 so that it is gradually moved by the regulating force. The locus T1 of the guide surface 33e is set so that the rapid rotation of the cam 32 is suppressed in the vicinity of the second shaft portion 32d passing the bent apex of the slit 27, . As an example of the condition of the locus T1, the regulating force by the guide surface 33e is set to be insufficient until the second shaft portion 32d passes from the main guide path 27a through the curved portion into the atmosphere path 27b And the regulating force is relaxed after the second shaft portion 32d passes through the curved portion and reaches a predetermined position in the atmosphere path 27b. Therefore, the operation at the time of the rotation is performed gradually and smoothly.

The engagement with the striker 10 is released by the restricted rotation. At the same time, the second shaft portion 32d reaches the standby position of the front end of the main guide path 27a, the second shaft portion 32d enters into the lower atmosphere path 27b and is returned again by the tension coil spring 41 And returns to the stand-by state held at the standby position. Thereafter, the movement of the sliding door M is released from the pushing force of the tension coil spring 41. Then, the striker 10 is released and returns to the first state shown in Fig.

Next, as a third operation, a return operation from the third state in which the latch 22 is moved to the retracted position without being engaged with the striker 10 due to, for example, a malfunction will be described.

9, when the sliding door M is moved in the first direction with respect to the supporting body from the third state in which the latch 22 is in the retracted position in the state in which the engagement with the striker 10 is released, A part of the cam 32 (here, the hook 32f) comes into contact with the striker 10 and is pushed backward as shown in Fig. With this pressing, the cam 32 is pivoted while being rotated in the R1 direction while the first shaft portion 32b is moved downward along the retraction path 27c with the second shaft portion 32d as the center. The upper end of the hook 32f of the catcher 32a is retracted downward from the passage of the striker 10 by this rocking motion so that the striker 10 can be passed over the hook 32f and moved along the X direction So that it can move in the pulling direction to a position where it can be engaged with the latch 22.

9, when the projecting portion 12c of the striker 10 overcomes the hook 32f, the cam 32 is rotated in the R2 direction by the restoring force of the tension coil spring 41, The striker 10 and the latch 22 are engaged by being inserted into the second engaging concave portion 12d. 9, in a state in which the striker 10 is caught by the latch 22, when the sliding door M is moved in the second direction (the direction away from the movement end position) in this engaged state, And is moved along the path 27a. Upon reaching the predetermined position, the engagement between the contact body and the keeper is released, and the contact state is returned to the first state in which the contact body is held at the standby position.

According to the present embodiment, it is possible to prevent the impact sound when the striker 10 and the latch 22 are engaged by interposing the restricting slider 33 that restricts the rotation of the cam 32. [ That is, by regulating the posture and the position of the cam 32 by the regulating guide portion 33c of the regulating slider 33, the clearance between the striker 10 and the cam 32 is kept to be minimum, The movement is followed by the operation of the sliding door M to make it difficult to generate a difference in moving speed between the striker 10 and the cam 32 so that the shock can be avoided and a smooth operation can be performed.

The present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the gist of the present invention. The specific configuration, material, etc. of each part are not limited to those illustrated in the above embodiments, and can be appropriately changed.

The restricting slider 33 is arranged to be slidable in the first direction and the second direction. However, in order to prevent wobbling, the restricting slider 33 is constantly pushed toward the striker 10 (forward) by using a compression coil spring or the like as the second pushing means .

In the above embodiment, the case where the assist unit 20 is provided on the side of the sliding door M serving as the movable body and the striker 10 is provided on the side of the door frame F as the supporting body is exemplified. However, The striker 10 may be provided on the movable body side and the assist unit 20 may be provided on the support body side. Although the striker 10 having a different structure is illustrated in the first embodiment and the second embodiment, the striker 10 is not limited to the striker 10, and for example, the combination may be changed.

In the above embodiment, the case where the movable body is the sliding door M is exemplified. However, the present invention can also be applied to other movable bodies such as a door door, a lift door, and the like.

In the present embodiment, a case has been exemplified in which the engagement recess portions 12b and 12d are provided for the normal use and the malfunction return, and the hook 32f is coupled to another position. However, the normal application and the malfunction return It may be combined at the same position in the application. In this case as well, it is oscillated in the retreating direction so that it can be retracted and recombined in the same manner as in the above embodiment.

Although the above embodiment has been described on the basis of one sliding door M, the present invention is also applicable to the case where two or more sliding doors M and the assist unit 20 are actually provided.

Further, the present invention can be realized by omitting some of the structural requirements of the above-described embodiment.

The entire contents of the specification, claims, drawings and summary of Japanese Patent Application No. 2011-280403 filed on December 21, 2011 are hereby incorporated herein by reference in their entirety and as a disclosure of the specification of the present invention .
