Japanese Utility Model Publication No. 5-78877 JP 2004-100225 A

  In the structure of Patent Document 1, the lid is opened and closed by an automatic opening / closing device, and can be opened manually by a manual automatic switching mechanism, which is convenient, but an automatic switching device, a drive motor, and an automatic manual switching mechanism are provided. Since it is equipped, it becomes expensive and there is a problem such as an increase in weight. On the other hand, the easy closer mechanism exemplified in Patent Document 2 is designed to eliminate the annoyance of having to push hard to overcome the reaction force of the vehicle body side seal member when the lid is fully closed. Has been adopted.

  That is, in an ordinary vehicle, on the assumption that the lid is manually opened and closed, an easy closer mechanism that automatically retracts from a little before the fully closed position to the fully closed position as exemplified in Patent Document 2 is adopted, The urging means biases in the opening direction to assist the opening operation, or the braking means brakes so as not to rotate rapidly in the closing direction with a load.

  For this reason, in the lid closing operation, there is a possibility that a finger or the like may be pinched between the opening edge of the vehicle body side when the lid is rotated from the open to the closing direction because the lid is rotated by grasping with the hand. . This is because, for example, even if the lid is equipped with an easy closer mechanism, the retraction is started slightly before full closure, that is, when the finger does not enter the gap with the opening edge on the vehicle body side, This is because even when the brake is operated by the means and operated in the closing direction, the braking force becomes weaker as it approaches the fully closed state.

  Therefore, an object of the present invention is to improve the opening / closing operability by pulling the moving body from the middle with a relatively simple pull-in mechanism, or to perform a bridge until it is pulled in with the easy closer mechanism. It is possible to eliminate the possibility of pinching.

  In order to achieve the above-described object, the present invention uses a biasing force of a biasing means to move a movable body that is rotatably attached to a main body via a hinge device from the first position to the second position of the main body. In the retracting mechanism of the rotating moving body, a housing provided on the main body side, a slider that is slidably disposed on the housing and slid by the urging force of the urging means, and the slider A pull-in unit having a locking means that locks against the biasing force of the biasing means, a swinging arm that is rotated in synchronization with the rotation of the movable body, and the movable body at the first position. And connecting the swing arm and the slider when reached, and a direction changing and connecting means for releasing the locking of the locking means, and when the movable body is rotated to the first position, Front through direction change and connection means To release the engagement of the locking means, is characterized in that rotates to a second position with the sliding of said slider by said biasing means.

In the above moving body retracting mechanism, the first position is any of the fully open position, the fully closed position, and the intermediate position, and the second position is any of the fully closed position, the fully open position, and any intermediate position different from the intermediate position. It is. More preferably, it is embodied as follows.
(1) The swing arm is fixed to a hinge arm constituting the hinge device or a pivot shaft of the hinge arm (claim 2).
(2) It has a braking means which is arranged in the housing and brakes the rotational speed of the moving body via the slider (Claim 3).
(3) An easy closer mechanism that is a vehicular lid that opens and closes the opening of the main body, and is retracted from a position just before the fully closing the opening to a fully closed position. And the second position is set to a position at which the lid is started to be pulled in the fully closed direction by the easy closer mechanism.

  According to the first aspect of the present invention, the pull-in mechanism is constituted by the pull-in unit, the swing arm and the direction changing / connecting means, and when the moving body is rotated to the first position, the direction change is connected to the swing arm. The locking means is unlocked from the slider via the cum connecting means, and is rotated to the second position via the slider slid by the biasing force of the biasing means. For this reason, the retracting mechanism is suitable when the moving body is a rotating lid, and is simple and does not require a power source such as a motor. Can provide.

  According to the second aspect of the present invention, the swing arm is fixed to the rotation shaft (support pin or the like) of the link as in the embodiment, or the front side of the rod-shaped hinge of FIG. 8 is pivotally supported by the vehicle body side bracket. By fixing to the pivot shown in the figure, the lid side output portion can be easily secured, and the degree of freedom can be given to the installation location of the retracting unit only by changing the entire arm size.

  In the invention of claim 3, the moving body is pulled in by the urging force of the slider and the urging means. At that time, the moving body is pulled in at a low speed braked by the braking means, so that a high-class feeling can be given. In this case, the retracting unit can be made compact by using the piston damper as the braking means as in the embodiment and arranging the piston damper on the inner diameter side of the coil spring as the urging means.

  In the invention of claim 4, since the moving body is pulled in from the middle of opening by the retracting mechanism of the present invention as in the embodiment, the fully closed position is still pulled in by the easy closer mechanism, so that the finger or the like mentioned in the problem The possibility of pinching can be reliably eliminated. As a result, the present invention can improve usability and safety.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows an application example of the present invention, FIGS. 2 and 3 show an example of the structure of a retracting mechanism, and FIGS. In the following description, the application example, mechanism features, and operation will be described in detail in the order. 4 to 7, reference numeral 44 in each (b) is a convex portion projecting on both sides of the rear side of the rotary lever, and although it does not appear in the drawing on the drawing, the relationship with the escape hole 33 on the slider side. This is shown for easy understanding. Of course, the convex portion 44 can be constituted by a shaft similar to the shaft 46 on the front side, and in this case, it appears as shown in the figure. Further, each drawing-in unit 2 of (a) shows a schematic positional relationship between the hinge device 8 and the convex portions 31b and 32b (slider) and the convex portion 54 (striker). For this reason, details such as the stopper 37 are omitted.

(Application example) Here, an application example of a retracting mechanism, a hinge device, and an easy closer mechanism will be described. The retracting mechanism 1 shown in FIG. 1 is incorporated in the retracting unit 2 including a slider 3, an urging spring S and a locking means 4, a swing arm 17 on the hinge device 8 side to be described later, and the retracting unit 2. A direction changing and connecting means 5 for operatively connecting the arm 17 and the slider 3 of the retracting unit 2 is provided, and a vehicle lid 7 such as a trunk lid attached to the vehicle body 6 via a hinge device 8 is opened. From the middle of the rotation operation in the closing direction (first position) to a position slightly before full closing (second position). That is, the vehicular lid 7 is supported at the front edge via the left and right hinge devices 8 and 8 with respect to the front side corresponding part of the vehicle body side opening 6a such as a trunk room, and the fully open position where the opening 6a is exposed to the maximum. When manually rotating from the first position to the first position, the retracting mechanism 1 rotates using the biasing force of the biasing spring S from the first position to the second position, and then the lid swing end side and the opening are opened. An easy closer mechanism 9 provided between the rear corresponding portion of the portion 6a is automatically retracted to the fully closed position.

  Here, in FIG. 1, reference signs a to e indicate opening positions of the lid 7. Position a is the fully open position of lid 7 (110 degree rotation), position b is midway position of lid 7 (65 degree rotation), position c is midway position of lid 7 (30 degree rotation), and position d is lid 7. The e position is a standby position (1 degree rotation) where the lid 7 starts to be pulled in the fully closed direction by the easy closer mechanism 9. In this example, the first position corresponds to the d position, and the second position corresponds to the e position that is the standby position of the easy closer mechanism 9.

  Moreover, as shown in FIG. 1 and FIG. 4A, the hinge devices 8 on both sides are of a type called a four-link structure, and are fixed bracket 10, movable bracket 11, fixed bracket 10 and movable. The front link 12 and the rear link 13 are interposed between the bracket 11 and the bracket 11. Among these, the fixing bracket 10 is mounted on the vehicle body 6 side in a substantially horizontal state with a bolt or the like. The movable bracket 11 is attached in the front-rear direction on the inner surface side of the base end of the lid 7. The fixed bracket 10 and the movable bracket 11 are pivotally connected to each other via support pins 14a and 14b on both ends by a rear link 13 disposed on the rear side of the vehicle body and a front link disposed on the front side of the vehicle body. 12 is rotatably connected via support pins 15 and 16 on both ends. In this hinge device 8, the basic structure described above is the same as the conventional one, but the support pin 15 that connects the lower end of the front link 12 and the front end of the fixed bracket 10 is changed.

  That is, the support pin 15 is configured to allow the swing arm 17 to rotate in synchronization with the lid 7 and protrudes from the large-diameter head 15a as schematically shown in FIG. For example, the shaft portion includes a head-side engagement shaft portion 15 b that is inserted and locked in an engagement hole provided at the lower end of the front link 12, and a fitting hole provided in the front end of the fixed bracket 10. It has a fitting shaft portion 15 c inserted through the member M and an engagement shaft portion 15 d inserted and locked in an engagement hole 17 a provided at the upper end of the swing arm 17. The cylindrical member M is provided with a front flange portion, is rotatably fitted to the fitting shaft portion 15c, and is engaged with a groove portion provided around the fitting shaft portion 15c. The lateral shift is prevented by the stopper C. The front flange portion of the cylindrical member M maintains a gap between the front ring 12 fixed to the engagement shaft portion 15b and the fixed bracket 10 fitted to the engagement shaft portion 15c. In other words, the support pin 15 has the engagement shaft portion 15b inserted and locked with respect to the lower end side engagement hole of the front link 12 and rotated integrally with the front link 12, and the fitting shaft portion 15c Through the front end side fitting hole of the fixed bracket 10 and the engaging shaft portion 15d is inserted and locked to the upper end side engaging hole 17a of the swing arm 17 so that the swing arm 17 is integrated. Make it pivotable.

  The easy closer mechanism 9 is provided between the lid 7 and the corresponding portion of the opening 6a, and automatically retracts from a little before the lid 7 reaches the fully closed position (position e in FIG. 1) to the fully closed position. Is. In this example, since it is the same as that of Patent Document 2, details are omitted. However, the latch mechanism 18 provided inside the rocking end of the lid 7 and the latch mechanism provided in the rear corresponding portion of the vehicle body side opening 6a. 18 and a closer device 19 having a striker engaged with and disengaged from 18 and an actuator for driving the striker. Of course, as the easy closer mechanism 9, the closer device 19 may be provided on the lid 7 side, and the latch mechanism 18 may be provided on the rear corresponding portion of the opening 6a.

(Mechanism Features) Here, the retracting unit 2 and the direction changing / connecting means 5 constituting the retracting mechanism 1 will be described. First, the retracting unit 2 is slidably disposed in the housing 20 and slidable by the biasing force of the biasing spring S, and the slider 3 resists the biasing force of the biasing spring S. The slider 3 is provided with at least the locking means 4 for locking and the brake piston damper 60 and is slid by the biasing force of the biasing spring S as a pulling force. Further, the direction changing / connecting means 5 includes a turning lever 40 constituting the locking means 4, a striker 50, a cam 56 and a torsion spring S1, and when the lid 7 reaches the first position. The swing arm 17 and the slider 3 are coupled to each other, and the locking of the locking means 4 is released.

  Details of the pull-in unit 2 are as follows. As shown in FIGS. 3 and 4, the housing 20 has a rectangular solid body that is elongated in the front-rear direction, the main body has a substantially U-shaped cross section, and the lower surface extends horizontally in the front-rear direction to slide the slider 3 and the striker 50. A guide section 22 having a concave cross section for guiding is provided, and a lower guide groove 23 that extends horizontally on the lower and front sides and guides the sliding of the slider 3 and the striker 50 on both side surfaces 21 and a cam located on the front upper side. 56, a front guide groove 25 for guiding the swinging of 56, a rear guide groove 26 which is positioned on the rear upper side to guide the sliding of the rotary lever 40 and which constitutes the locking means 4, and is positioned approximately in the middle of the front and rear. Thus, a pair of engagement holes 20a opened at the upper and lower portions sandwiching the lower guide groove 23 are provided. Here, the front guide groove 25 includes a straight groove portion 25a extending horizontally in the front-rear direction and an arc groove portion 25b extending downward from the front side of the straight groove portion 25a. The rear guide groove 26 includes a linear groove portion 26a that extends horizontally in the front-rear direction and a locking groove portion 26b that extends downward at a right angle from the front side of the linear groove portion 26a. Although the drawing is partially simplified, the front side of the straight groove portion 26a (upper side of the locking groove portion 26b) is formed as an inclined surface, and the rear end surface of the locking groove portion 26b is arcuate, that is, the rotating lever 40 is The convex portion 44 is formed in an arc shape when the shaft 46 is rotated about the fulcrum. The upper and lower pieces 37a of the stopper 37 are inserted into the engagement hole 20a. That is, the stopper 37 forms a locking portion for the spring member corresponding to the upper and lower piece portions 37 a in the housing 20 by inserting the upper and lower piece portions 37 a into the respective engagement holes 20 a facing the both side surfaces 21.

  Further, the front end opening of the main body is closed by the front member 27, the rear end opening is closed by the rear member 28, and the upper opening is closed by the upper surface member 29 except for the front portion. It becomes a container with a predetermined rigidity that is substantially closed except for the front portion. The rear member 28 is attached with a fixture 38 for fixing a rod 62 of a piston damper 60, which will be described later, and an adjuster 39 for adjusting the backward sliding position of the slider 3. In a state where the fixing member 38 is attached to the rear member 28, a cylindrical portion 38a for attaching the tip of the rod 62 protrudes forward in the housing. In this case, although the drawing is simplified, in actuality, the fixture 38 is positioned and arranged on the inner surface of the rear member 28 and is fixed from the outside with a screw or the like. The adjustment tool 39 is constituted by, for example, a bolt, and adjusts the rear sliding position of the slider 3 by a protruding amount screwed into the housing 20 via a nut portion attached to a corresponding portion of the rear member 28. is there. The upper surface member 29 has a window 29a that is open on both sides and an opening 29b that is largely lacking in the front portion. The window 29 a is a part that escapes from the rear guide groove 26, and also has a function of easily bending and deforming when the upper surface member 29 is incorporated into the housing 20. The opening 29b is a place that prevents the cam 56 from swinging and the swing arm 17 from entering. In this example, the housing 20, the front member 27, and the rear member 28 are press products such as metal plates, and the top member 29 is a resin molded product. However, the material is arbitrary. Further, the upper surface member 29 is formed of a metal plate or the like as necessary to give rigidity, or a reinforcing plate or the like is attached together with the upper surface member 29.

  The slider 3 integrally forms a cylindrical portion 30 that is long in the front-rear direction and a substantially plate-shaped front leg portion 31 and a rear leg portion 32 that are provided on the lower surface of the cylindrical portion 30 and protrude downward from the front-rear end. The cylindrical part 30 is formed in a cavity from the front end opening to the front and rear substantially middle part, is located on both sides, and is close to the front end side with a vertical escape hole 33 provided slightly opposite the rear part from the front end side. It has a shaft hole 34 that is provided at a location and penetrates in the width direction. The front and rear leg portions 31 and 32 are circular holes 31a and 32a provided in the center and penetrating front and rear, convex portions 31b and 32b provided on both side surfaces, and a convex portion 31c provided on the lower surface. , 32c.

  The protective cylinder 47 is attached to the slider 3 while being held in the circular hole 31 a of the front leg portion 31 and the circular hole 32 a of the rear leg portion 32. That is, the protective cylinder material 47 has a cylindrical portion that protrudes from the lower half of the mounting plate portion 47 a and penetrates in the front-rear direction, and the cylindrical portion connects the mounting plate portion 47 a to the outer end surface of the rear leg portion 32. It is held in the front circular hole 31a and the rear circular hole 32a in the mounted state. From this state, the slider 3 is put in the housing 20, and the convex portions 31 b and 32 b are fitted into the respective lower guide grooves 23, and the convex portions 31 c and 32 c are fitted into the aforementioned guide portion 22. Thus, the housing 20 is incorporated so as to be slidable back and forth. Further, before and after that, the piston damper 60 and the biasing spring S are incorporated in the housing 20. The biasing spring S and the piston damper 60 are general-purpose products.

  Among them, the urging spring S is a coil-shaped spring material, and is attached so as to be wound around the outer periphery of the cylindrical portion of the protective cylinder material 47 when the protective cylinder material 47 is attached to the slider 3. Then, as shown in FIG. 7, the urging spring S has a rear end locked to the inner end surface of the rear leg portion 32 and a front end locked to the upper and lower piece portions 37 a of the stopper 37 attached to the housing 20. The urging force is stored when the slider 3 is slid forward. On the other hand, the piston damper 60 includes a cylinder 61 and a rod 62 that gently protrudes and retracts in the cylinder 61, and the cylinder 61 can be gently driven with respect to the rod 62 fixed via the fixture 38. (See JP-A-2005-188893 etc.).

  The above-described locking means 4 includes a rotating lever 40 that is swingably assembled to the slider 3, that is, a convex portion 44 of the rotating lever 40 and a rear guide groove 26 on the housing 20 side. Among these, the rotation lever 40 is substantially T-shaped as shown in FIG. 3, and includes a horizontal piece 41, a vertical piece 42 projecting downward substantially in the middle of the horizontal piece 41, and a horizontal piece 41. A hook portion 43 that protrudes downward on the front side is integrally formed. The horizontal piece portion 41 has such a size that the rear side is inserted with a margin into the slider side cylinder portion 30 and is located on both sides and penetrates in the one-width direction slightly behind the vertical piece portion 42. It has the hole 45 and the convex part 44 which protrudes on the one side surface of the back. The vertical piece 42 has a through-hole 42a provided in the center and penetrating in the front-rear direction. The through hole 42 a is a hole having a hole diameter substantially the same as that of the circular hole 31 a of the front leg portion 31 and slidably inserted through the cylinder 61 of the piston damper 60. The hook portion 43 maintains a predetermined gap with the vertical piece portion 42.

  The rotating lever 40 described above has the convex portions 44 on both sides in the corresponding cylindrical portion side relief holes 33 in a state where the rear side portion of the horizontal piece portion 41 is inserted into the cylindrical portion front opening with respect to the slider side cylindrical portion 30. After loose-fitting, the shaft 46 is inserted into the one shaft hole 34 of the cylinder portion, the shaft hole 45 on the rotation lever side, and the other shaft hole 34 of the cylinder portion, so that the shaft 46 can be turned up and down with the shaft 46 as a fulcrum. Built-in swingable. In the state shown in FIG. 4, the pivot lever 40 engages with the engaging groove portion 26 b of the rear guide groove 26 from the lower position in the escape hole 33, so that the slider 3 moves to the biasing spring S. It is locked at the foremost position where the urging force is stored. As shown in FIGS. 6 and 7, when the rotation lever 40 is rotated clockwise with the shaft 46 as a fulcrum via the striker 50 or the like, the convex portion 44 moves to the upper position in the escape hole 33. As a result, the movement is released from the locking groove 26b of the rear guide groove 26 and the locking is released. The slider 3 is slid rearward by the urging force of the urging spring S together with the rotation lever 40 by releasing the locking.

   The direction changing / connecting means 5 includes a rotating lever 40, a striker 50, a cam 56 and a torsion spring S1, and when the lid 7 reaches the first position, the swing arm 17 and the striker 50 are connected to the cam 56. Or the like, or the striker 50 and the slider 3 are operatively connected via the hook portion 43 of the rotating lever 40 or the like, and the locking of the locking means 4 is released, that is, the locking groove 26b. The engagement or locking of the convex portion 44 of the rotation lever 40 with respect to can be released.

  Here, the striker 50 is substantially in the shape of a container disposed in the housing 20, and is provided on the lower surface side to be fitted with the guide portion 22 on the housing side, and on the rear side is provided with a rotating lever. A concave connecting hole 51 for engaging and disengaging the hook portion 43 on the side, a front space 52 provided on the front side of the connecting hole 51 so that the lower side of the cam 56 is swingably disposed, and provided on both side surfaces for width A shaft hole 53 penetrating in the direction and convex portions 54 provided in front of and behind the shaft hole 53 are provided. On the other hand, the cam 56 is provided with a linear cam groove 57 provided in the upper portion and extending downward from the upper end, a shaft hole 58 provided in the lower portion and penetrating in the plate width direction, and from the upper end. It has a mounting hole 59 provided on the front side at a slightly lower position and penetrating in the plate width direction.

  The above cam 56 is inserted into the one shaft hole 53 of the striker 50, the shaft hole 58 of the cam 56, and the other shaft hole 53 of the striker 50 with the lower portion inserted into the striker side space 52. By performing the retaining process, the striker 50 is assembled so as to be rotatable in the front-rear direction with the shaft 49 as a fulcrum. From this state, the striker 50 is inserted into the housing 20, the convex portion 50a on the lower surface is fitted into the guide portion 22 on the lower side of the housing, and the convex portions 54, 54 on both sides are below the both sides of the wing. By being fitted into the guide groove 23, the housing 20 is incorporated so as to be slidable back and forth. Further, the cam 56 is inserted (fitted) into the one-side front guide groove 25 of the housing 20 from the state where it is disposed in the housing 20 together with the striker 50, and is inserted (engaged) into the mounting hole 59 of the cam 56. ) And inserted into (fitted with) the front guide groove 25 on the other side of the housing 20 so as to be rotatable. In the above operation, the torsion spring S1 locks the base end portion on the shaft 49 side and the operating end portion on the shaft 48 as shown in FIG. For this reason, the cam 56 is held in the state of FIG. 4B by the urging force of the torsion spring S1, and is rotated counterclockwise (rotating against the urging force) with the shaft 49 as a fulcrum. At the same time, the rotation trajectory is regulated by the front guide groove 25 fitted to both ends of the shaft 48.

(Operation) As described above, the pull-in unit 2 is attached to the use location illustrated in FIG. 1 with the direction changing / connecting means 5 incorporated in the common housing 20. In that case, as a positioning reference, the position of the cam 56 constituting the direction changing and connecting means 5 is adjusted so that it can be operatively connected to the swing arm 17 described above. The swing arm 17 is rotated integrally with the support pin 15 and has a U-shaped opening 17b on the lower end side. A shaft 36 is provided in the opening 17b so as to cross the opening as shown in FIG.

  Next, an operation example of the above-described retracting mechanism 1 will be outlined with reference to FIGS. FIG. 4 shows a state in which the lid 7 is rotated in the closing direction from the fully open position (position a in FIG. 1) to an opening angle of about 65 degrees (position b in FIG. 1). In this state, the swing arm 17 is rotated clockwise through the front link 12 and the support pin 15 of the hinge device 8 in synchronization with the front link 12, and the shaft 36 on the lower end side of the cam groove 57 of the cam 56 is moved. Enter the entrance side.

  FIG. 5 shows a state in which the lid 7 is further rotated in the closing direction to an opening angle of about 30 degrees (position c in FIG. 1). In this process, the cam 56 is rotated in the vertical (standing) direction with the shaft 49 as a fulcrum (while the shaft 36 is moved to the back of the cam groove 57) by the rotation of the swing arm 17 (at the time of this rotation). After the shaft 48 is moved from the arc groove 25b to the linear groove 25a), the shaft 48 is further slid rearward together with the striker 50 as shown in FIG. In this case, the striker 50 hits the cylinder 61 (rear end face) of the piston damper 60 as shown in FIG. 5, and hits the vertical piece 42 of the rotating lever 40 while pushing the cylinder 61 rearward as shown in FIG. .

  Then, the rotation lever 40 is rotated clockwise around the shaft 46 by the stress received from the striker 50. As a result, the hook portion 43 engages with the connecting hole 51 of the striker 50, and the slider 3 and the striker 50 And the convex portion 44 moves to the upper side of the locking groove 26b and is unlocked (FIG. 6).

  Therefore, thereafter, as shown in FIG. 7, the slider 3 is accompanied by the guide action of the lower guide portion 22 and the convex portions 31c and 32c on the housing side, and the lower guide groove 23 and the convex portions 31b and 32b on the housing side. The striker 50 is slid rearward by the urging force of the urging spring S, and in conjunction with this sliding, the cam 56 is kept in a substantially vertical (stand-up) state and the straight groove portion 25a of the front guide groove 25 described above together with the striker 50. And the convex portion 54 are slid in the same direction. Thereby, the swing arm 17 is rotated clockwise through the operation connection between the shaft 36 and the cam groove 57 while the striker 50 and the cam 56 are slid rearward. This converts the linear motion on the striker 50 side into rotational motion via the cam 56 (cam groove 57) and the shaft 36. As a result, the lid 7 is automatically pulled from the position d in FIG. 1 to the position e in synchronization with the rotation of the swing arm 17.

  In the above automatic retraction process, when the slider 3 is slid by the urging force of the urging spring S together with the striker 50, the lid 7 is gently slid under the braking of the piston damper 60. When the lid 7 is pulled to the position e in FIG. 1, the lid 7 is automatically pulled to the fully closed position by the easy closer mechanism 9 thereafter.

  When the lid 7 is opened again, the lid 7 is unlocked and the lid 7 is pushed up in the opening direction as in the conventional case. Then, the lid 7 is rotated in the direction of the position a from the position e in FIG. In this case, in relation to the retracting unit 2, the urging force is stored in the urging spring S via the slider 3 until the lid 7 reaches the position d in FIG. 1, that is, the state in FIG. 6.
